Abstract

A pressure head with foaming function mounted onto a container with liquid substances includes a low-pressure suction force generator with a reducing port set into the discharge pipe of the pressure head, such that liquid already absorbed to the discharge pipe can flow through the guide port of the discharge pipe. The liquid is then collected and extruded from the reducing port, thus increasing the flow speed and reducing the pressure to generate a low-pressure suction force. An it guide port is arranged onto the discharge pipe and also located at a spacing with the reducing port. While the liquid is extruded from the reducing port to generate low-pressure suction force, air out of the discharge pipe is absorbed from the air guide port to the discharge pipe, such that an is mixed with liquid, making the liquid extruded from the discharge pipe foamed.

  • The present invention relates generally to a pressure head, and more particularly to an innovative one which is designed with foaming function.
  • Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
  • Sonic bottles or containers are commonly used to accommodate creamy liquids such as hand cleanser and shampoo. The opening of previous containers is often sealed by a cover to prevent leakage of liquid. Yet, a pressure head is designed to be installed at the opening of the container, allowing the users to easily fetch the liquid in the container without repetitively opening or closing the cover.
  • As for the common pressure head, the liquid is often pumped by a piston member from the tube of the pressure head, and the pressure head is not available with an additional function. So, when the liquid is extruded by the pressure head, the users have to rub it (e.g.: shampoo) manually such that it can be mixed with air to generate foam uniformly. It is thus learnt that the functionality of the traditional pressure head cannot meet diversified, user demands due to imperfect operability and applicability. Encountered with the competitions from similar pressure heads, there is a great concern on how to make a breakthrough progress for developing a novel pressure head structure to improve the competitiveness.
  • Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved, structure that can significantly improve the efficacy.
  • Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
    • BRIEF SUMMARY OF THE INVENTION
  • Based on the “pressure head with foaming function” of the present invention, the low-pressure suction force generator in the discharge pipe is mated with the air guide port, so that liquid is extruded from the reducing port of the low-pressure suction force generator. Meanwhile, air out of the discharge pipe is absorbed from the air guide port into the discharge pipe, such that air is mixed with liquid, making the liquid extruded from the discharge pipe in a foaming state. The present invention also has an additional foaming function. So, the extruded liquid is kept in a foaming state only if the user presses the pressing portion. As compared with prior art, the liquid in the present invention can generate foam without need of extra rubbing. In such a case, the liquid could be used more conveniently and smoothly. On the other hand, based on the design of the guide column formed in the discharge pipe, the liquid already absorbed to the discharge pipe can flow around the guide column for desired guide effect, thus improving substantially the ease-of-use and applicability to meet the user demands.
  • Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.

    •  DETAILED DESCRIPTION OF THE INVENTION
  • FIGS. 1-7 depict preferred embodiments of the pressure head of the present invention with foaming function, which, however, are provided for only explanatory objective. Said pressure head is mounted onto a container A with liquid substances (e.g.: band cleanser, shower gel, shampoo).
  • The pressure head includes a main body 10, comprising of a main tube body 12 with a piston member 11, a pressing portion 13 connected at top of the main tube body 12, and a liquid suction portion 14 connected at lower part of the main tube body 12. Of which, the liquid suction portion 14 is fitted with a pipette (e.g. arrow 05 in FIG. 1). The pressing portion 13 comprises of a discharge pipe 15 with guide ports 131A, 131B. When the pressing portion 13 is triggered for reciprocating motion, the piston member 11 absorbs liquid, in the container A from the liquid suction portion 14, and then the liquid accumulated in the pistol member 11 is absorbed into the discharge pipe 15. Here, the piston member 11 absorbs liquid in the same way as in prior art. Referring to FIG. 2, said guide port 131A can be directly formed into the discharge pipe 15, or referring to FIGS. 3, 4, a guide column 151 is formed in the discharge pipe 15, while said guide port 131B is formed between the guide column 151 and inner wall of the discharge pipe 15.
  • A low-pressure suction force generator 20 is annularly arranged at a preset location of the discharge pipe 15.
  • A reducing port 30 is formed onto the low-pressure suction force generator 20 in an axial penetration state. When liquid. (e.g.: arrow L1 in FIG. 7) is absorbed to the discharge pipe 15 through the guide port 131B, it is then collected and extruded from the reducing port 30 of low-pressure suction force generator, thus increasing the flow speed of liquid and reducing the pressure to venerate a low-pressure suction force.
  • At least an air guide port 50 is arranged at a preset location of the discharge pipe 15, and also located at a spacing with the reducing port 30 of the low-pressure suction force generator 20. While the liquid is extruded from the reducing port 30 to generate low-pressure suction force, air out of the discharge pipe 15 (e.g.: arrow L2 in FIG. 7) is absorbed from the air guide port 50 to the discharge pipe 15, such that air is mixed with liquid, making the liquid extruded from the discharge pipe 15 in a foaming state (shown by arrow L3 in FIG. 7).
  • Based upon the above-specified structural design, the present invention also has an additional foaming function. So, the extruded liquid is kept in a foaming state only if the user presses the pressing portion 13. As compared with prior art, the liquid of the present invention extruded from the pressure head can generate foam without need of extra rubbing. In such a case, the liquid could be used more uniformly, conveniently and smoothly, thus improving substantially the ease-of-use and practicability to meet the user demands.
  • Referring to FIGS. 4-6, the low-pressure suction force generator 70 of the present invention is sleeved into the discharge pipe 15, opposite to the guide column 151 at a spacing When the liquid is absorbed to the discharge pipe 15, it flows from the guide port 131B into the low-pressure suction force generator 20, where it is collected and extruded from the reducing port 30.
  • Referring also to FIGS. 3-6, the discharge pipe 15 comprises of an education tube 16 protruded from the pressing portion 13 and a supplementary tube fitting 17 mated with the education tube 16. Of which, said guide column 151 is formed into the supplementary tube fitting 17, and the air guide port 50 is opened on the periphery of the supplementary tube fitting 17. A mating portion 18 is set correspondingly to the periphery of the education tube 16 and the inner side of the supplementary tube fitting 17, so that the supplementary tube fitting 17 and the low-pressure suction force generator 20 are incorporated and connected to the education tube 16.
  • Referring also to FIG. 8, a guide wall 41 of predefined shape is formed at inner surface of the low-pressure suction force generator 20, such that the periphery of the guide column 151 could be mated with the guide wall 41 so as to guide the liquid already absorbed to the discharge pipe 15. Of which, a guide groove 42 of predefined shape is formed on the low-pressure suction force generator 20 adjacent to the end wall of the reducing port 30, such that liquid can be guided to the reducing port 30. In the preferred embodiment, the guide groove 42 is in a radiating state by taking the reducing port 30 as its axis, and the guide wall 41 is in a flat tangent plane state.
