Description

Technical Field

[0001] The utility model belongs to the technical field of breathing valves, and in particular relates to a novel portable breathing valve. Background Art

[0002] The mask in the prior art is a kind of sanitary and epidemic prevention product, which is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. In order to improve comfort, some masks are equipped with a breathing valve, which is a one-way valve. The positive pressure of the exhaust gas during exhalation blows the valve open to quickly expel the waste gas in the body and reduce the stuffiness when using the mask. The negative pressure during inhalation will automatically close the valve to avoid inhaling pollutants from the external environment.

[0003] A Chinese patent with application number CN202021238098.1 discloses a breathing valve, including a valve seat, a valve core and a valve cover. The valve cover is detachably connected to the valve seat, a breathing chamber is formed between the valve cover and the valve seat, and a first air vent and a second air vent connected to the breathing chamber are respectively provided on the valve cover and the valve seat, and the valve core is arranged in the breathing chamber; the valve core includes a valve core body and a limiting boss, the valve core body is a foldable and retractable tubular structure, one end of the valve core body is connected to the valve seat, and the other end of the valve core body is connected to the limiting boss, the limiting boss can be slidably arranged in the first air vent, and a sealing ring is arranged between the valve core body and the limiting boss.

[0004] The above technical solution solves the technical problems of poor opening and resetting of the valve sheet in the breathing valve and easy damage of the valve sheet. However, in actual application, since the breathing valve is a one-way valve, when the patient uses a mask with a breathing valve, it can appropriately increase comfort in a sterile environment or a solitary environment. However, when the patient carries a mask and is in a crowd, he or she must either replace it with a mask without a breathing valve. If it cannot be replaced, it is very easy to cause the spread of the virus, resulting in a lower scope of application when used for different groups of people or occasions.

[0005] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0029] The utility model will now be further described in detail with reference to the accompanying drawings.

[0030] See also Figure 1-6 As shown, in this embodiment, a new portable breathing valve is provided, including a breathing valve body 1 and a mounting seat 2, a mounting frame 17 that is slidably matched with the mounting seat 2 is fixedly connected to the lower side of the breathing valve body 1, two card slots 3 are provided on both sides of the mounting seat 2, and a card block 4 that matches the card slot 3 is fixedly connected to the inner wall of the mounting seat 2;

[0031] The mounting seat 2 is the same as the mounting hole of the breathing valve of the protective mask in the reference document;

[0032] A vent hole 5 is provided on the lower side of the mounting seat 2, a hollow plate 6 is fixedly connected to the lower side of the inner wall of the mounting seat 2, an adjustment plate 7 is slidably and elastically matched to the inner wall of the hollow plate 6, and a filter frame 8 matching the vent hole 5 is fixedly connected to one side of the adjustment plate 7;

[0033] A linkage mechanism 9 is installed on the lower side of the inner wall of the mounting seat 2 and on one side of the hollow plate 6 .

[0034] The application of one aspect of this embodiment is as follows: when in use, when a person who is not a virus carrier carries the mask, the mounting seat 2 is fixed in a predetermined vent hole on the mask, and then the mounting frame 17 is inserted into the mounting seat 2, so that the card block 4 is inserted into the card slot 3 to be fixed. After the mounting frame 17 enters the interior of the mounting seat 2, it will cause compression with one end of the seesaw 903 in the linkage mechanism 9, so that the other end of the seesaw 903 opens the filter frame 8, so that a connection is generated inside the card slot 3, and then breathing is promoted through the breathing valve body 1. The breathing valve body 1 can be a commonly used N95 mask breathing valve or a breathing valve with the same principle as that in the comparative document;

[0035] When a virus carrier uses it in a crowded environment, the breathing valve body 1 can be pulled out with force, so that the mounting frame 17 is pulled out from the inside of the mounting seat 2. After the breathing valve body 1 is separated as a whole, it can be directly put into a pocket for carrying due to its small size. After being pulled out, the mounting frame 17 is separated from the rocker 903, and the adjustment plate 7 and the filter frame 8 are pushed to seal the air hole 5 under the action of the reset spring 16. The filter frame 8 can be a circular frame with a filter cloth, and the cloth can be made of mask cloth material, which has the function of filtering viruses. When the filter frame 8 closes the air hole 5, the carrier's virus can be prevented from being discharged through the breathing valve, so that it can be adjusted according to the usage situation, thereby improving the scope of environmental applicability.

[0036] By setting the installation frame 17, the breathing valve body 1 and the mounting seat 2 can be assembled or disassembled. After disassembly, the internal sealing of the air vent 5 is achieved. After installation, the air vent 5 is separated by the filter frame 8 to increase air fluidity and facilitate the use of the breathing valve body 1. This allows the use of the breathing valve to be adjusted for different groups of people, thereby improving the scope of application to the environment.

[0037] The linkage mechanism 9 of this embodiment includes two lifting plates 901 fixedly connected to one side of the inner wall of the mounting base 2, a load-bearing rod 902 fixedly connected to the side close to the two lifting plates 901, and a seesaw 903 rotatably engaged on the load-bearing rod 902 and in contact with the bottom of the adjustment plate 7. One end of the seesaw 903 extends to the lower side of the adjustment plate 7. When the other side of the seesaw 903 is subjected to pressure, the lower side of the adjustment plate 7 will pry the adjustment plate 7 upwards, thereby opening the relationship between the filter frame 8 and the air vent 5.

[0038] A rubber ring 10 is fixedly connected to one side of the mounting base 2 of the present embodiment. The rubber ring 10 is provided with a plurality of ventilation holes 11. The rubber ring 10 improves the comfort of contact with the user's face and avoids clogging of the ventilation hole 5 due to close contact with the skin.

[0039] A detachable protective cover 12 is fixedly connected to one side of the breathing valve body 1 of the present embodiment. The detachable protective cover 12 and the breathing valve body 1 can be connected by snapping or screwing. The components inside the breathing valve body 1 can be cleaned by removing the detachable protective cover 12 for recycling, thereby saving costs.

[0040] A guide groove 13 is provided on one side of the inner wall of the mounting seat 2 of the present embodiment, and a guide block 14 is fixedly connected to the breathing valve body 1 and slidably cooperates with the guide groove 13. When assembling and installing to the mounting seat 2 and the breathing valve body 1, the guide block 14 is inserted into the direction of the guide groove 13 for guidance, so that the clamping block 4 and the clamping groove 3 can be quickly docked.

[0041] The inner wall of the hollow plate 6 of the present embodiment is fixedly connected with a limit rod 15 which cooperates with the adjustment plate 7. The adjustment plate 7 and the hollow plate 6 are provided with a return spring 16 which is sleeved on the limit rod 15. When the adjustment plate 7 moves up and down, the limit rod 15 is used to guide it to increase stability. The return spring 16 is used to reset the adjustment plate 7 when it is not subjected to external force. The card slot 3 and the card block 4 are carded together, and the carding force is greater than the elastic force of the return spring 16.

[0042] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
