Description

Breathable ventilation sole with venturi effect

The present invention relates to a sole having a breathing ventilation effect, and more particularly to a breathing ventilating sole having a Venturi effect. Background technique

At present, various kinds of shoes with breathing and breathing function have appeared on the market. They all have a breathing and ventilation mechanism in the sole to make the shoes have a breathing and ventilation function. However, most of the breathable ventilation shoes of this structure are made of a separate airbag structure, which is easily damaged during actual use, and the structure thereof is relatively complicated. Therefore, a new structure has been explored. Respiratory ventilation shoes that replace the airbag structure.

With the continuous innovation of breathing and ventilation shoes, designers have developed a breathing ventilation shoe that applies the principles of fluid mechanics. For example, the sole disclosed in Chinese Patent Application No. 200710102098. 1 has a venturi-induced aeration effect. The sole of the structure is mainly provided for use by a motorcycle driver, and an airflow groove communicating with the outside atmosphere is provided in the sole. The air inlet of the air flow groove is disposed at the front end of the sole, and the air outlet of the air flow groove is disposed at both sides of the rear end of the sole. When the user wears the shoe to drive the motorcycle, the strong airflow impinging on the front end of the shoe flows in from the air inlet. The air flow groove is discharged from the rear air outlet, during which the air inlet high pressure area is formed at the front end of the air inlet, and the low air flow area is formed outside the rear air outlet, and a low pressure siphon force is formed in the low pressure area of the air flow to form a venturi in the area. The effect is that the airflow of the airflow groove in the sole is extracted, thereby achieving an induced ventilation effect on the airflow in the shoe. However, the actual use of the structural shoes and its use value is quite limited, mainly reflected in: (1) the shoe is only suitable for sports situations where the airflow forms a directional impact. If there is no impact airflow outside the shoe, the air outlet end of the shoe cannot Forming the Venturi effect, the inside of the shoe can not form its own active ventilation function; (2) The shoe is not suitable when the wearer walks, it is basically impossible to form the venturi induced ventilation of the outside atmosphere, the general walk It is impossible to form a strong airflow impact, and it is impossible to form a high pressure zone at the air inlet of the sole and a low pressure zone at the air outlet. Moreover, during the walking process, the foot swings back and forth, although the foot swings while walking. The strength is very large, and the high pressure zone formed by it is impossible to form. For example, in the high-pressure zone generated by the front end of the shoe when the motorcycle is driven by the airflow, the venturi induced by the shoe is very weak; (3) if the shoe is kept under induced ventilation, it cannot be in the dust storm, pollution, It is used in environments such as rainy days, snow, and small bacteria infections, which greatly reduces the environment in which the shoes are used.

For this reason, the actual use of the above-mentioned ventilating effect-inducing sole has greatly restricted the promotion and application of the product. The applicant believes that it is necessary to design a breathable sole that is more valuable to use. Summary of the invention

Description: The present invention is directed to a technical improvement made to the sole which is the portion of the shoe that contacts the ground and which is essential for all shoes. The primary function of the sole is to contact the ground while the wearer is walking to provide foot protection.

The invention will now be further described with reference to the accompanying drawings.

According to the embodiment shown in FIG. 1 to FIG. 2, the breathing ventilating sole having the venturi effect of the present invention comprises a sole body 1 whose bottom surface is directly in contact with the ground, and the upper surface is provided with an upper to constitute a shoe. The inner body of the sole body 1 is generally made of a wear resistant material and is generally composed of a heel portion 101, a bow portion and a forefoot portion. The present invention is directed to an improvement in the prior art in which a pipe 2 having a venturi effect is provided in the sole body 1, which pipe 2 must be structurally characterized by a venturi. The duct 2 includes an intake pipe 21, a throat 22, a siphon pipe 23, and an exhaust pipe 24 which are connected in series, and the exhaust pipe 24 communicates with an air outlet 3 provided at the heel portion 101 of the sole body 1. The inner diameter of the intake pipe 21 to the inner diameter of the throat 22 is reduced from large to small, and the inner diameter of the throat 22 to the inner diameter of the siphon 23 is expanded from small to large, and the intake pipe 21 and the throat The tube 22 and the siphon tube 23 are connected to form a venturi, as shown in Figs. 2-3 and 5-6, and Fig. 7 is a plan view of the duct 2 shown in Fig. 6. In a specific manufacturing process, the pipe 2 having the venturi effect disposed in the sole body 1 can be produced in the following three forms: (1) the pipe 2 is first made into a prefabricated pipe (ie, pre-formed) Tube device), the preformed tube member is inserted into the sole body 1 when the sole body 1 is molded, as shown in Fig. 1, Fig. 9-11; (2) the tube 2 having the venturi effect is evacuated in the form of a tube groove In the sole body 1, the tube groove is obtained by a certain manufacturing process when the sole body 1 is molded. As shown in FIG. 14, the figure cuts a portion of the sole at the position of the pipe 2 for clarity; 3) The pipe 1 is a pit 8 provided on the upper surface of the sole body 1, and the pit 8 is obtained according to the above-mentioned large-small-large inner pipe diameter requirement and the structure of the exhaust pipe 24, and the pit 8 is Formed by the curved groove structure, at the same time, the upper surface of the sole body 1 is provided with a sheet 9 which is airtightly pressed on the pit 8 to achieve the venturi effect, which satisfies the breathing of the sole body 1 Ventilation, as shown in Figure 15. In addition, in general, the exhaust pipe 24 may be provided with two, respectively disposed on both sides of the port of the siphon tube 23, and respectively communicate with the air outlet 3 on both sides of the heel portion 101 of the sole body 1; or, in order to make the siphon tube 23 better The siphon effect (Note: Since both exhaust pipes 24 are in communication with the outside, the vacuum effect of the siphon tube 23 is weakened, and the siphon effect of the siphon tube 23 is inevitably weakened), and the exhaust pipe 24 can be provided with a single one. The heel portion 101 of the sole body 1 opens an air outlet 3, and at the same time, avoids opening too many air outlets 3 in the heel portion 101 of the sole body 1 to affect the overall appearance of the sole, or closing one of the exhaust pipes 24 with a blockage. By operating one of the two exhaust pipes 24, the above-described effect of improving the siphon effect can also be achieved. The above-mentioned pipe 2 having a venturi effect, the intake port 211 of the intake pipe 21 absorbs the air in the sole of the shoe body 1 at the bottom of the sole body, and the airflow is discharged from the heel portion 101 of the sole body 1 through the above-described duct 2, during which the airflow A venturi effect occurs in the above-mentioned duct 2. When the user puts on the shoe with the sole of the present invention, due to the venturi effect, a negative pressure is generated in the siphon tube 23, and the airflow entering the intake pipe 21 and the throat 22 has a siphoning and air pulling action. Good realization of the breathing ventilation function of the sole.

As a further improvement of the above technical solution, the pipe 2 having the venturi effect is also the pipe 2 having the chimney effect, and the airflow flows through the pipe 2 formed by the connection of the intake pipe 21, the throat pipe 11, the siphon pipe 23 and the exhaust pipe 24 The chimney effect is generated, and after the airflow flows into the above-mentioned pipe 2, it is also subjected to the pumping effect of the chimney effect, thereby further improving the ventilation effect of the sole. The design or manufacture of the pipe 2 having the venturi effect as the pipe 2 having the chimney effect can be achieved in the following three ways: (1) For the above-mentioned pipe 2 having a chimney effect, the pipe 2 is along the intake pipe 21, the throat 22, the siphon 23 to the exhaust pipe 24 are sequentially inclined upwards, the structure is simple, and is convenient for production, as shown in Fig. 2-5. Meanwhile, the inclined design can be a ladder as shown in Fig. 2-5. Tilting upwards, it can also be inclined obliquely upwards. (2) extending the exhaust pipe 24 upward to form a chimney structure, and designing the exhaust pipe 24 as a chimney structure. Since the chimney itself has an upward siphoning effect on the gas, the sole can also have a better breathing and ventilation function. The air inlet pipe 21, the throat pipe 22 and the siphon pipe 23 are connected to form a venturi pipe which can be a horizontal straight pipe structure, and the air flow generates a venturi effect in the connection of the intake pipe 21, the throat pipe 11 and the siphon pipe 23, and then The exhaust pipe 24 of the chimney structure has a chimney effect, as shown in FIG. 8; or, while the exhaust pipe 24 is designed as a chimney structure, the intake pipe 21, the throat pipe 22, and the siphon pipe 23 are sequentially directed to the exhaust pipe 24 Tilting in the direction, making the pipe 2 with the venturi effect Venturi's siphoning effect with the chimney effect. (3) When the pipe 2 having the venturi effect is a horizontal straight pipe structure, as shown in Fig. 6-7, when the sole body 1 is molded, the pipe 2 of the straight pipe structure is arranged in the sole body 1 The trachea 24 is oriented obliquely upward.

At the same time, in the specific design and manufacture of the sole, the sole body 1 is provided with a breathing airbag 4, and the structure of the breathing airbag 4 is familiar to those skilled in the art or can be known through the footwear literature, and will not be described in detail herein. Its internal structure. The airflow ejected from the jet port of the air lance 41 of the breathing airbag 4 serves as a source of air absorbed by the intake port 211 of the intake pipe 21, and the airflow ejected from the air bag 4 serves as a stable air source for the above-mentioned stationery urinal effect tube 2. , optimizes the breathing and ventilation function of the pipeline 2. For the structure of the breathing airbag 4 provided in the present invention, as an optimized design, the following two forms can be further improved: (1) The sole body 1 is provided with a wind block 5, and the wind block 5 is located at the air inlet pipe 21. In front of the intake port 211, the windward surface of the choke 5 is a pointed arc surface structure, similar to the wing structure of the aircraft. When the airflow ejected from the airbag 4 is blocked by the choke 5, a Venturi effect is generated. The back side of the choke column 5 forms a low pressure region, so that the intake port 211 of the intake pipe 21 adsorbs the injected airflow, and the intake amount of the intake port 211 of the intake pipe 21 can be increased, as shown in FIG. 12; 2) The port of the air tube 41 of the breathing air bag 4 is inserted into the air inlet pipe 21, and the gas sucked into the air bag 4 is directly injected into the air intake pipe 21, so that the air intake pipe 21 obtains a more stable air flow, as shown in Fig. 13. Show.

At the same time, the above-mentioned breathing ventilating sole having a Venturi effect can also be provided with a breathing air pump 6 in the sole body 1, the bottom surface of the sole body 1 is provided with an air guiding groove 7, an air outlet pipe 61 of the breathing air pump 6, and an air guiding groove 7 communicating and supplying air to the air guiding groove 7, the air guiding groove 7 is in communication with the air inlet pipe 21 of the pipe 1 having the venturi effect, and the breathing air pump 6 can first realize the breathing ventilation function of the shoe, and can also be the sole The bottom provides a sufficient air source, and is installed in the sole with the above-mentioned venturi tube 2, so that the sole can achieve secondary ventilation, and the ventilation effect of the sole can be improved. During this period, the structure of the breathing air pump 6 can be made by the structure of the shock absorbing and ventilating member described in the "damping ventilating shoe" patent which I have applied for, and at the same time, the air outlet pipe 61 of the breathing air pump 6 can be long or short. It depends on the airflow of the sole. When the breathing apparatus 6 is not required to be provided on the sole body, the air guiding groove 7 can be used as the air circulation of all the embodiments of the sole, and the arrangement of the air guiding groove 7 on the upper surface of the sole body 1 can be determined according to actual manufacturing needs.

When the sole of the present invention is actually used, the insole 11 should generally be placed on the upper surface thereof, and at the same time, the insole 11 opens the corresponding ventilation hole 12 and the air hole communicating with the air outlet 3 of the insole portion 101 of the insole body 1, The venting opening 12 serves as an air flow effect on the upper surface and the lower surface of the insole 11, so that a sufficient air supply is provided above and below the sole to ensure the breathing effect of the shoe, and at the same time, the insole 11 can prevent the footstep from directly pressing on the ventilating member. The fact that the ventilation member is crushed up also increases the comfort of the wearer's foot.

Fig. 11 is a schematic view showing the structure of a breathing air bag 4 and a breathing air pump 6 in the embodiment of the present invention, which can form a turbulent flow in the shoe, and the ventilation effect is better.

Figure 16 shows the use state of the embodiment of the present invention, which can be flexibly used on a variety of different shoes, so that the shoe has a fluid-mechanical effect of breathing ventilation, greatly improving the quality of use and wearing comfort of the shoe, the sole product Low cost and easy to popularize.

During the use of the present invention, when the wearer walks, since the forefoot and the heel alternately press or tap the forefoot portion and the heel portion 101 of the sole, the continuous pressing action causes another breath in the sole to generate another breath. The air source other than the airbag 4 or the breathing air pump 6, as a stable air source for the duct 2, also contributes to the venturi effect of the duct 2 and promotes the breathing ventilation effect of the sole.

Due to the venturi effect of the present invention, a negative pressure is generated in the siphon tube 23, and the airflow entering the intake pipe 21 and the throat pipe 11 is siphoned and extracted, thereby better achieving the breathing and ventilation function of the sole. Moreover, the present invention has a simple structure, and the above-mentioned duct 2 is only required to be provided on the sole, and can be flexibly applied to any different shoes, so that the shoes have a breathing and ventilation effect, and the quality and wearing comfort of the ordinary shoes are greatly improved. In addition, the sole of the present invention is used without any environmental restrictions. Since the venturi tube 2 itself has a siphoning and air pulling effect on the gas, as long as there is air at the bottom of the sole, the inside of the shoe has a breathing breath. Effect, the shoe equipped with the present invention, whether the user is exercising or walking, or even when the user is sitting still, the shoes worn by the user are still actively exerting their breathing and ventilation effects.
