Description

Micro-lip-pasting epidemic prevention mask

Technical Field

The utility model relates to the technical field of masks, in particular to a micro-lip-pasted anti-epidemic mask with an anti-epidemic filter cloth arranged on a waste gas exhaust outlet.

Background

Aiming at various problems of small effective filtering area, unsmooth ventilation, extremely low replacement rate of large waste gas in a cavity in front of a mouth and uncomfortable wearing commonly existing in epidemic prevention masks and dust masks in the current market, the inventor has already reported a patent of { micro lip mask pasting }, and relatively comprehensive problem solutions are correspondingly provided. However, there is still a problem that is not solved in this patent: the exhaust gas exhaled from the mouth of people is directly exhausted outside the filter cloth of the mask, and if infectious germs in the mouth of people spread everywhere, the infectious germs can cause mutual infection. If we want to clearly illustrate the ideal effect of the new design with epidemic prevention function in the newly filed patent document, we must go through the partial working principle of the micro-lip mask, and we will go on to further elucidate below, because the general mask with valve can not be changed into the mask with epidemic prevention function and comfortable wearing.

The wearing of the mask makes people feel uncomfortable, and the problems of uneasy inspiration or incomplete replacement are not solved fundamentally.

Epidemic prevention gauze masks and dust masks commonly used by people are simply divided into two types: a cloth-shaped mask and a mask with a larger cavity in front of the mouth. What are the advantages and disadvantages of these two types of masks?

A cloth-shaped mask, such as a medical mask, has the advantages of low production cost and convenience in carrying and storage, but is not tight in wearing and small in effective filtering area, so that the air suction or exhaust speed is low; the mask with the large cavity is arranged in front of the mouth, the effective filtering area is large, air suction and exhaust are easy, but the production cost is relatively high, and the more important problem is that the waste gas exhausted from the cavity in front of the mouth for a long time occupies the cavity in front of the mouth for a long time, and the waste gas replacement rate is seriously influenced.

Here, it is important to explain that the mask has a relatively large cavity in front of the mouth and an exhaust valve: people add an exhaust valve on a mask with a larger cavity in front of the mouth, aiming at discharging most of waste gas from the exhaust valve more smoothly. However, the effect is not good in practical use. The reason is that: the front of the mouth is provided with a large cavity, the exhaust valve is far away from the lips of people, and the exhaust valve is opened later only after the whole cavity is filled with the exhaust gas breathed by people and a certain positive pressure is formed in the cavity. Because the exhaust valve must be a normally closed valve, the valve plate needs to withstand a certain pressure before it can open. When the exhaust gas is exhausted, most of the compressed exhaust gas is exhausted by the mask filter cloth, and the positive pressure in the cavity is late, so that the effect of exhaust gas installation on accelerating exhaust gas exhaust is not obvious. Another problem to be explained is: if infectious germs are carried in the mouth of a person, the waste gas in the inner cavity of the mask is directly discharged out through the exhaust valve, and the germs can be diffused all around to infect each other.

In summary, no ideal mask which can realize easy suction and discharge, high exhaust gas replacement rate and comfortable wearing exists in the market so far, and no epidemic prevention mask which can isolate germs on the basis of the ideal mask exists. What is there a solution to the above problem? I made the following attempt.

Disclosure of Invention

The utility model aims at the technical problem and solves the technical problem by providing a micro-lip-sticking epidemic prevention mask with the following structure, which comprises a mask belt, a lip sticking edge, an exhaust guide pipe, mask filter cloth and adjusting screws, wherein the lip sticking edge is formed at one end of the exhaust guide pipe, the other end of the exhaust guide pipe is fixed on the mask filter cloth by the adjusting screws and is externally provided with an exhaust gas exhaust outlet, epidemic prevention filter cloth is arranged at the exhaust gas exhaust outlet, and the mounting position of the exhaust guide pipe is adjusted by the adjusting screws according to the approaching degree of the lip sticking edge and the lips when the mask is worn.

Furthermore, a sealing port and a one-way valve plate are arranged on the exhaust guide pipe to form one-way exhaust of the exhaled exhaust.

Optionally, the sealing port and the check valve plate are arranged in the exhaust gas guiding pipe in a matched manner.

Optionally, the closeout lip is provided at the end of the exhaust conduit proximate to the lip.

Optionally, the exhaust gas guide pipe is positioned in the middle of the mask filter cloth.

Compared with the existing mask with an exhaust valve in the market and the micro lip-sticking mask invented by the inventor, the micro lip-sticking epidemic prevention mask has the following advantages:

firstly, compared with the existing mask with an exhaust valve in the market: a large cavity is arranged in front of a mouth of a mask with an exhaust valve in the market, the exhaust valve is arranged at the front end of the cavity, and the exhaust valve is far away from the lips. When people exhale, the exhausted waste gas is filled in the cavity in front of the whole mouth immediately, and the exhaust valve opens to exhaust after a certain positive pressure is generated in the cavity. Because the gauze mask filter cloth is the material of ventilating, and the area is great, as long as there is little pressure gauze mask filter cloth just beginning to leak gas in the cavity, so, need form certain malleation in the cavity and just open the discharge valve and need a longer process, wait the discharge valve to open, the exhalation process has just ended, consequently, so installation discharge valve can not play the effect that is showing to the discharge of waste gas. This mask has two further disadvantages: because the whole front cavity of the mouth is filled with the waste gas, when people inhale, the waste gas in the cavity is firstly inhaled, the amount of fresh air really inhaled and filtered by the filter cloth of the mask is very small, and the replacement rate of the waste gas is very low; in addition, the exhaust valve, although it does little to replace the exhaust gas, has more or less always some exhaust gas to be directly discharged. If a person already carries the germs, the discharged germs spread all around to cause mutual infection. If a layer of epidemic prevention filter cloth is added at the outlet of the exhaust valve, the problem of germ diffusion can be solved, and the function of the exhaust valve for assisting exhaust gas replacement is almost completely lost because the air is not as short-cut as the air directly passes through the filter cloth of the mask. The utility model relates to a micro lip-attached epidemic prevention mask, which is mainly derived on the basis of the function of a micro lip-attached mask invented by the inventor, and epidemic prevention filter cloth can be added to prevent the transmission of germs only under the condition of the mask function of keeping the original pressure of exhaust and intensively discharging. The core principle is as follows: the exhaust gas exhaled by people must keep the original pressure to be discharged outside in a concentrated manner, so that the effect of complete replacement of the exhaust gas is realized, and the exhaust gas exhausted in a concentrated manner keeps the original pressure, so that the exhaust gas can be rapidly exhausted by the subsequently installed epidemic prevention filter cloth. The main structural characteristics of the micro-lip-pasting epidemic prevention mask are as follows: a sealing port and a one-way valve plate are arranged on the exhaust guide pipe to form one-way exhaust of exhaled exhaust; according to the characteristics that people have a slightly higher upper lip, the lips are opened and closed mainly by the movement of lower jaw tissues, the lips are slightly contracted when air is inhaled, the lips are slightly expanded when air is exhaled, and people can easily and naturally discharge exhaled air from the middle of the lips, the lip attaching edge of the end of the exhaust guide pipe is slightly attached to the lips by properly adjusting the adjusting screw, so that air inhaled by the respirator filter cloth and exhaust gas exhaled by the respirator are all intensively discharged from the exhaust guide pipe under the original pressure, the discharged exhaust gas is filtered by the epidemic prevention filter cloth, the external discharge of harmful bacteria is strictly avoided, and the ideal wearing effect that the exhaust gas is completely replaced, the pathogenic bacteria are inhaled particularly easily and the propagation is effectively controlled is realized.

Secondly, compared with the { micro-lip mask } invented by the inventor: in short, the operating principle of the micro lip-attached mask is that all exhaust gas exhaled by people is directly blown into the lip-attached edge close to the lips, and a one-way valve plate is rapidly opened by utilizing strong airflow and is directly exhausted outside through an exhaust gas guide pipe, so that the problems of unsmooth inhalation and exhalation or low exhaust gas replacement rate in the existing mask are solved. However, the exhaled exhaust gas is directly discharged without being filtered, which leads to the diffusion and the transmission of germs, and the application range of the mask is greatly reduced, so that the mask is not suitable for medical use and epidemic prevention. At the same time we should see that: the airflow from such a mask can be maintained at its original pressure and is a concentrated discharge, a feature that is not available in all types of masks currently on the market. If we add a filter cover made of epidemic prevention filter cloth at the exhaust outlet of exhaust gas, the problem of poor epidemic prevention performance is not solved? Therefore, the inventor invents a micro-lip-sticking epidemic prevention mask. The mask does not need to change the main structure of the { micro-lip mask }, only a set of epidemic prevention filter cloth needs to be additionally arranged at the exhaust outlet of waste gas, the original excellent mask performance is improved, and an epidemic prevention function is added.

Detailed Description

So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the utility model, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention, and the described embodiments are merely a subset of the embodiments of the present invention, rather than a complete embodiment. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Fig. 1 is a schematic structural view showing an embodiment of the slight lip stick epidemic prevention mask of the present invention.

Referring to fig. 1, the mask belt 1 is formed on both sides of the mask filter cloth 6. The position of the exhaust gas guide pipe 5 of the middle structure of the mask filter cloth 6 is fixed by an adjusting screw 7. The sealing port 3 and the one-way valve plate 4 are arranged in the exhaust gas guide pipe 5 in a matching way. The pasting lip 2 is arranged at the end of the exhaust gas guide pipe 5 close to one end of the lip. The other end of the waste gas guide pipe 5 is a waste gas outlet 8. The periphery of the exhaust gas outlet 8 is tightly sealed by the epidemic prevention filter cloth 9.

In the specific implementation: if the sealing lip 3 is arranged at the end of the exhaust gas conducting pipe 5 close to the lips, the outer frame of the sealing lip 3 directly replaces the lip 2. The lip edge 2 is shaped like a circle, a square, an ellipse or the like with moderate size and is locally convex. The positions of the sealing port 3 and the one-way valve plate 4 are arranged or the end heads or the middle parts of the two ends of the waste gas guide pipe 5. The sealing port 3, the check valve plate 4, the adjusting screw 7 and the exhaust gas guide pipe 5 mounted on the mask filter cloth 6 can be produced as a single assembly for adapting to the corresponding type of mask filter cloth. The epidemic prevention filter cloth 9 is not limited by size and structural shape, and is convenient to store according to the conditions of no sight shielding, occupying less space and being attractive and elegant as possible on the premise of ensuring smooth exhaust.

When people wear the mask: after the mask belt 1 is hung, the periphery of the mask filter cloth 6 is enabled to be closely matched with the face of a person, then the adjusting screw 7 is adjusted to enable the lip attaching edge 2 to be slightly attached to the lips, the attaching force is based on the standard that the lips can be slightly changed to suck air, and most of waste gas can directly rush into the lip attaching edge 2 during normal exhalation.

When a person inhales air: because the sealing port 3 and the one-way valve plate 4 are a set of one-way valves, when people inhale air, the valves are in a closed state, and the air filtered by the mask filter cloth 6 can be easily inhaled into the mouths of people as long as the lips of people slightly change.

When a person exhales waste gas: as one part of the lip sticking edge 2 is stuck to the lips and the other part is extremely close to the lips, the lip can be slightly changed as long as people intentionally discharge waste gas from the lip sticking edge 2 when exhaling. If the lip is expanded to a large extent during exhalation, a small amount of waste gas is not directly centered in the pasting lip 2, and the strong air flow passing through the pasting lip 2 can generate negative pressure around the pasting lip 2, then the small amount of waste gas can be sucked into the pasting lip 2, and then the waste gas is flushed into the epidemic prevention filter cloth 9 from the waste gas guide pipe 5 through the waste gas discharge port 8 through the check valve plate 4. Because the airflow pressure is higher, the speed of the waste gas passing through the epidemic prevention filter cloth 9 is fast, and the exhaust speed is not influenced.

The utility model can be changed and modified in various ways, and is not limited to the specific structure of the above embodiments, such as the shape, size and installation position of the lip, the sealing port, the one-way valve plate and the exhaust gas guiding pipe. In summary, the scope of the utility model should also include such exchanges, substitutions and alterations as will be apparent to those skilled in the art.
