Abstract
The invention discloses an air filter unit. An air conveying mechanism which is used for conveying air flowing in a filter cavity to an air outlet and a filter net which is used for filtering the air conveyed to the air outlet are arranged in the filter cavity of the air filter unit. When working, excess air flow power is provided by the air conveying mechanism, so that external air can automatically flow into the filter cavity without suction of a user; the air filtered through the filter net in the filter cavity flows into a nasal cavity after passing through the air outlet, later the air is sucked by the user, and then the air exhaled by the user is discharged from a vent hole, so that sucking resistance of the user is greatly reduced, and the crowd with weak respiratory function can breathe smoothly. Meanwhile, an endonasal socket which extends a nostril is adapted to the nostril of the user and closely fitted with the inner wall of the nostril, so that peripheral leakage is prevented, and air filtering effect is guaranteed; the nasal cavity is small, so that nasal and oral area of the user are not covered, and the air filter unit is comfortable to wear and beautiful.
Description
Technical field
The present invention relates to a kind of air filter, particularly a kind of air filter breathed.
Background technology
At present, people mainly adopt mouth mask to carry out the materials such as dust in filtered air, pollen, virus or bacterium, to improve the quality of the air sucking human body.And mouth mask is generally designed to the nose and the mouth that cover user, it exists following not enough: 1, cannot fit tightly between the edge of mouth mask and face, cause the leakage occurred between mouth mask and face peripherally, reduce the air filtration effect of mouth mask.2, mouth mask covers the face comprising mouth and nose, and wearing can be caused uncomfortable, and meanwhile, mouth mask outward appearance is unsatisfactory again, so a lot of people can refuse to wear face shield because it cannot be made satisfied for the comfort level of mouth mask and aesthetics.3, mouth mask has certain obstruction to air, needs to strengthen the dynamics of breathing during breathing, and for the more weak crowd (such as empty nose syndrome patients or bronchus patient) of respiratory function, and mouth mask then can cause it to breathe more difficult even appearance suffocating.
Summary of the invention
The object of the present invention is to provide a kind of effect of breathing better, and breathe air filter more smoothly.
A kind of air filter of the present invention, comprise body, body is provided with the filter chamber that can flow into for extraneous air, the gas outlet of filter chamber is led to by conduit and attached nasal cavity body, the gas transmission mechanism that the air flowed in it is transferred to gas outlet and the screen pack that the air transferring to gas outlet is filtered is provided with in filter chamber, attached nasal cavity body have exhaust outlet and at least one can stretch into nostril and enter nose socket with nostril is suitable mutually, by entering nose socket, nostril is communicated with attached nasal cavity body, exhaust ports has cover plate, cover plate is connected with the flexible member on attached nasal cavity body, when the gas pressure in attached nasal cavity body be less than or maintain an equal level the external gas pressure time, exhaust outlet is closed from outside by cover plate, when the gas pressure in attached nasal cavity body is greater than the external gas pressure, cover plate then pushed away from exhaust outlet.
Air filter of the present invention, the gas transmission mechanism that the air flowed in it is transferred to gas outlet and the screen pack that the air transferring to gas outlet is filtered is provided with in filter chamber, during work, extra gas mobilization dynamic is provided by gas transmission mechanism, make extraneous air user's air-breathing automatically need not can flow into filter chamber, and by after the filter screen filtration in filter chamber, flow to through gas outlet in attached nasal cavity body, for in user's suction body, the gas that user breathes out then flows out from exhaust outlet, significantly can reduce the resistance of user's air-breathing, the breathing of the crowd that the function that ensures respiration is more weak is smooth and easy.Meanwhile, the nose socket that enters stretching into nostril is fitted mutually with user nostril, fits tightly with nostril, there will not be the situation that circumference leaks, ensure air filtration effect, and can attached nasal cavity body be done less, the nose of user and oral area can not be covered, can ensure that wearing is comfortable and attractive in appearance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of body of the present invention.
Fig. 3 is the structural representation of attached nasal cavity body of the present invention.
Detailed description of the invention
As shown in Figures 1 to 3, described air filter, comprise body 1, body 1 is provided with the filter chamber 11 that can flow into for extraneous air, the gas outlet 12 of filter chamber 11 is led to by conduit 13 and attached nasal cavity body 6, the gas transmission mechanism 3 that the air flowed in it is transferred to gas outlet 12 and the screen pack 4 that the air transferring to gas outlet 12 is filtered is provided with in filter chamber 11, power is provided by this gas transmission mechanism, make extraneous air user's air-breathing need not can flow into filter chamber 11 from outside, and after filter screen 4 filters, flow to through gas outlet 12 in attached nasal cavity body 6, attached nasal cavity body 6 have exhaust outlet 61 and at least one can stretch into nostril and enter nose socket 62 with nostril is suitable mutually, by entering nose socket 62, nostril is communicated with attached nasal cavity body 6, there is cover plate 63 at exhaust outlet 61 place, described cover plate 63 can be made up of plastic cement, cover plate 63 is connected with the flexible member 7 on attached nasal cavity body 6, when the gas pressure in attached nasal cavity body 6 be less than or maintain an equal level the external gas pressure time when user does not exhale (gas transmission mechanism 3 do not work and), cover plate 63 can be closed from outside by exhaust outlet 61, prevent the air of filtered from entering attached nasal cavity body 6, and when the gas pressure in attached nasal cavity body 6 is greater than the external gas pressure (gas transmission mechanism 3 work or user exhale when), cover plate 63 pushed away from exhaust outlet 61, the gas that filtered air or user breathe out outwards flows out from the gap between cover plate 63 and exhaust outlet 61.When the present invention works, extra gas mobilization dynamic is provided by gas transmission mechanism 3, extraneous air is made user's air-breathing can need not automatically to flow into filter chamber 11, and after being filtered by the screen pack 4 in filter chamber 11, flow to through gas outlet 12 in attached nasal cavity body 6, in user's suction body, the gas that user breathes out then flows out from exhaust outlet 61, significantly can reduce the resistance of user's air-breathing, the breathing of the crowd that the function that ensures respiration is more weak is smooth and easy.Meanwhile, the nose socket 62 that enters stretching into nostril is fitted mutually with user nostril, fits tightly with nostril, there will not be the situation that circumference leaks, ensure air filtration effect, and can attached nasal cavity body 6 be done less, the nose of user and oral area can not be covered, can ensure that wearing is comfortable and attractive in appearance.
