Compared with the prior art, the beneficial effects of the present invention are:

(1) When the wearer is sitting or standing still, the breathing is relatively gentle, and the oxygen demand is not very large. At this time, when the wearer inhales for the first time, a negative pressure is generated in the air inlet nasal obstruction sheath, and the air enters through the air inlet. The air enters the air inlet chamber and enters the bottom of the filter housing through the air guide channel. The gas is filtered through the filter layer and enters the top of the filter housing. Then a part of the filtered gas enters the air inlet nasal plug sheath and is inhaled through the traditional Chinese medicine box. In the human body, another part of the filtered gas enters the respirator through the corrugated hose 2. Since the human body needs less oxygen when sitting or standing still, at this time, the part of the gas entering the respirator can be continued according to the It is inhaled into the human body through the mouth to supply the remaining gas required by the human body, and another small part of the gas enters the power chamber through the corrugated hose and is discharged from the air outlet. When the required amount of oxygen is required, the gas entering the breathing mask can all enter the power chamber through the corrugated hose and be discharged through the air outlet. Compared with the existing ordinary masks, it is avoided that there is excess gas in the breathing mask. Causes the wearer to experience stuffiness and dampness.

(2) When the wearer exhales, it can only be exhaled through the mouth, and the gas exhaled by the wearer can only enter the power chamber through the corrugated hose 2, because the constriction located in the corrugated hose 1 gradually decreases , the air pressure from the port located in the power chamber of the corrugated hose increases and blows on the screw drive blade, so that the rotating shaft rotates, and the rotating shaft rotates at the same time to drive the intake fan located on the rotating shaft in the intake chamber to rotate, and the intake fan rotates. When rotating, the outside air enters the air intake chamber through the air inlet, and then enters the filter through the air guide channel for filtration, and replenishes the air in the air filter device.

Played the role of turning waste into treasure.

(3) When the wearer is walking or exercising, the breathing is more frequent, so the demand for oxygen supply also increases. When the wearer walks, the air intake fan is driven to rotate rapidly by the outside wind, so that a large amount of air passes through the air inlet and is in the air. Under the action of the intake fan, it enters the air filter device through the air guide channel. When the wearer inhales, a negative pressure is generated inside the filter housing, and under the combined action of the positive pressure of the intake fan, a large amount of gas enters the air filter device. After filtering, a part of the gas enters the human body directly through the air inlet nasal plug sheath, the other part enters the breathing mask through the corrugated hose 2, and is inhaled into the human body through the mouth, and a small part of the gas enters the power chamber through the corrugated hose 1 and enters the power chamber. Compared with the nasal air purifier used in the prior art, the air is discharged from the air outlet, which avoids the increase of the wearer's oxygen demand during the exercise process, which leads to the wearer's poor breathing and hypoxia.

(4) When the wearer is exhaling, positive pressure is generated in the nostrils, and the exhaled gas enters the breathing mask through the corrugated hose 20. Due to the positive pressure generated in the nostrils, the filtered air in the inhalation nasal obstruction protective cover Under the action of positive pressure, the gas stays in the air intake nasal congestion protective cover, and the wearer needs to inhale immediately after exhaling the gas, and the filtered gas located in the air intake nasal congestion protective cover is negative pressure generated by the wearer's inhalation Under the action, it immediately enters the nostrils for the wearer to absorb in time, avoiding the phenomenon of hypoxia.

(5) The edge of the breathing mask described in the present invention is provided with a sealing airbag ring, which plays a sealing role to prevent the outside world from entering the breathing mask and being absorbed by the wearer, and the outer wall of the top of the filter housing is provided with a sealing gasket , sealing the nostrils of the human body with a sealing gasket, preventing the unfiltered air from being directly inhaled into the human body from the nostrils of the human body, and improving the sealing performance of the whole device.

(6) In the present invention, the bottom end of the air inlet nasal obstruction sheath is provided with a traditional Chinese medicine box for holding traditional Chinese medicine dregs, and the temperature in the nostrils of the human body is used to preheat and heat the traditional Chinese medicine dregs, which can further improve the efficacy of the traditional Chinese medicine.

(7) The traditional Chinese medicine box in the present invention includes an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate are connected with a slot, so that the traditional Chinese medicine box can be quickly disassembled, thereby facilitating the replacement of traditional Chinese medicine residues. The end face and the lower end face of the lower cover are made of gauze. The gauze has good air permeability and will not block the filtered air, thereby avoiding affecting the wearer's normal breathing, and the diameter of the gauze mesh is smaller than the diameter of the traditional Chinese medicine residue, preventing wearing During the inhalation process, the medicinal residues pass through the traditional Chinese medicine box and are inhaled into the human body from the nostrils of the human body.

(8) In the present invention, the traditional Chinese medicine box is detachably connected to the air inlet nasal plug sheath, which facilitates the replacement of the traditional Chinese medicine box. The side wall of the lower cover plate is symmetrically provided with hanging ears, and the bottom end side wall of the air intake nasal plug sheath is along the side wall. Its length is provided with a fixing slot, and the bottom of the fixing slot is provided with a limit slot that matches the hanging ear. When the Chinese medicine box needs to be replaced, lift the Chinese medicine box to the inner top of the air inlet nasal plug sheath, so that the hanging ear is free from the limit. Pull up from the groove, and then stand up the Chinese medicine box by hand, and then the Chinese medicine box can be taken out from the air intake nasal obstruction sheath.

(9) The traditional Chinese medicine box in the present invention is detachably connected to the air inlet nasal obstruction sheath, so that different types of traditional Chinese medicine residues can be replaced according to the wearer's situation and needs. When the wearer wears it during the day, put the traditional Chinese medicine box into the The traditional Chinese medicine dregs made of burdock dregs, mint dregs, dendrobium dregs and honeysuckle dregs, after the purified air is absorbed by the body under the action of Chinese herbal dregs, it will clear the lungs, moisten the throat and refresh the wearer.

When in use: First, fix the breathing mask 1 on the mouth of the human body through the fixing belt 1 4. Since the bottom edge of the breathing mask 1 is provided with a sealing airbag ring 3, the mouth of the human body can be well sealed to prevent unfiltered air from the outside world. The air enters into the breathing mask 1, and at the same time, the two air intake nasal obstruction sheaths 2 are inserted into the nostrils of the human body, and the air intake nasal obstruction sheath 2 is fixed with the fixing belt 2 15, and the air supply mechanism is located on the human face. At the middle position, because the outer wall of the top end of the filter housing 12 is provided with a sealing gasket 22, the sealing gasket 22 blocks the edge of the nostril of the human body, thereby playing a sealing role, preventing the unfiltered air from entering the nostril of the human body for the human body to inhale, and After the two are fixed, when the wearer is sitting or standing still, the breathing is relatively gentle, and the oxygen demand is not much. At this time, when the wearer inhales for the first time, a negative pressure is generated in the air inlet nasal sheath 2, and the air passes through the air intake. The port 9 enters the intake chamber 5b, and enters the bottom of the filter housing 12 through the air guide channel 10. The gas is filtered by the filter layer 13 and enters the top of the filter housing 12, and then a part of the filtered gas enters the intake nasal congestion. The sheath 2 is inhaled into the human body through the traditional Chinese medicine box 16, and another part of the filtered gas enters the breathing mask 1 through the corrugated hose 20. Since the human body needs less oxygen when sitting or standing still, At this time, the part of the gas entering the respirator mask 1 can be inhaled into the human body through the mouth to supply the remaining gas required by the human body, and another small part of the gas enters the power chamber 5a through the corrugated hose-11 It is also discharged from the air outlet 8 (at this time, a small part of the gas will not blow the rotating shaft 7 to rotate), when the gas entered by the wearer through the nostrils has satisfied the amount of oxygen required by himself, the gas entering the breathing mask 1 can be completely It enters the power chamber 5a through the corrugated hose-11 and is discharged through the air outlet 8. The end of the air outlet 8 that communicates with the corrugated hose-11 and the air supply chamber 5 is symmetrically arranged about the rotating shaft 7 to avoid the breathing mask 1. There is excess gas in the wearer, which causes the wearer to suffocate. When the wearer exhales, it can only be exhaled through the mouth, and the gas exhaled by the wearer can only enter the power chamber 5a through the corrugated hose-11 Inside, because the constriction of the corrugated hose-11 is gradually reduced, the air pressure from the port of the corrugated hose-11 located in the power chamber 5a becomes larger and blows on the screw driving blade, so that the rotating shaft 7 rotates, and the rotating shaft 7 At the same time, it drives the intake fan located on the rotating shaft 7 in the intake chamber 5b to rotate. When the intake fan rotates, the outside air enters the intake chamber 5b through the intake port 9 and then enters through the air guide channel 10. It is filtered in the filter to replenish the gas in the air filter device. In the whole process, only the exhaust gas exhaled from the human mouth is used as the power source of the intake fan, and no electronic control equipment is required, which not only avoids the use of electricity for the intake fan The danger brought to the wearer by providing a power source, at the same time, the exhaust gas exhaled by the human body is turned into a power source, which plays the role of turning waste into treasure. When the wearer is walking or exercising, he breathes more frequently, so oxygen supply The demand for volume also increases, and when the wearer walks, The air intake fan is driven by the outside wind to rotate rapidly, so that a large amount of air passes through the air inlet 9 and enters the air filter device through the air guide channel 10 under the action of the air intake fan. When the wearer inhales, the filter housing 12 Negative pressure is generated inside and under the combined action of the positive pressure of the intake fan, a large amount of gas enters the air filter device after filtering, part of the gas directly enters the human body through the intake nasal plug sheath 2, and the other part enters through the corrugated hose 20. The breathing mask 1 is sucked into the human body through the mouth and a small part of the gas enters the power chamber 5a through the corrugated hose-11 and is discharged from the air outlet 8 to prevent the wearer from increasing the oxygen demand during exercise, which may cause the wearer The phenomenon of lack of oxygen occurs due to poor breathing. Similarly, when the wearer exhales, the gas exhaled by the wearer can only enter the power chamber 5a through the corrugated hose-11. It gradually decreases, so that the air pressure from the port of the corrugated hose 11 located in the power chamber 5a increases and blows on the screw drive blade, so that the rotating shaft 7 rotates, and the rotating shaft 7 rotates at the same time. The air intake fan on 7 rotates. When the air intake fan rotates, the outside air enters the air intake chamber 5b through the air inlet 9 and then enters the filter through the air guide channel 10. For replenishment, when the wearer exhales, positive pressure is generated in the nostrils, and the exhaled gas enters the respiratory mask 1 through the corrugated hose 2 20. Due to the positive pressure generated in the nostrils, the filter located in the air intake nasal congestion protective cover 2 The latter gas stays in the air intake nasal obstruction protective cover 2 under the action of positive pressure, and the wearer needs to inhale immediately after exhaling the gas, and the filtered gas located in the air intake nasal congestion protective cover 2 is inhaled by the wearer. The generated negative pressure immediately enters the nostrils for the wearer to absorb in time, avoiding the phenomenon of hypoxia. When the wearer wears it during the day, remove the air intake nasal plug sheath 2 from the filter housing 12, and then put the The Chinese medicine box 16 is lifted to the inner top of the air inlet nasal obstruction sheath 2, so that the hanging ears 17 are pulled up from the limiting groove 19, and then the Chinese medicine box 16 is erected by hand, so that the Chinese medicine box 16 can be removed from the air inlet nasal obstruction sheath. 2, put the Chinese medicine box 16 into the Chinese medicine dregs made of burdock dregs, mint dregs, dendrobium dregs and honeysuckle dregs, the wearer wears it during the day, and the purified air is in the air of the traditional Chinese medicine dregs. After being absorbed by the human body under the action, it will have the effect of clearing the lungs, moistening the throat and refreshing the mind. It can also be worn when the wearer is sleeping at night. At this time, it is only necessary to replace the traditional Chinese medicine residue in the traditional Chinese medicine box 16 with lavender. The traditional Chinese medicine slag mixed with the slag, the slag of night vine vine and the slag of Boziren can be used. When the wearer wears it at night, the purified air will be absorbed by the body under the action of the slag of the traditional Chinese medicine, which will nourish the wearer's mind and calm the nerves. For the function of sleep aid, since the traditional Chinese medicine box 16 is detachably connected to the air inlet nasal obstruction sheath 2, different types of traditional Chinese medicine residues can be replaced according to the wearer's needs.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it is still possible to modify the technical solutions described in the foregoing embodiments, or to perform equivalent replacements for some of the technical features.
