TWM531291U - A breath mask with airflow bypass - Google Patents

Abstract

A breath mask with airflow bypass comprises a mask body covering the mouth and the nose of a user, a divider, a filter module, and a hanging unit. The divider, the masker, and the face of the user jointly define an upper air chamber and a lower air chamber separated from each other. The filter module includes a base unit connected to the outer surface of the mask body, and a filter unit detachably connected to the base unit and defining a chamber unit that includes divided nose-connecting room which is communicated with the upper air chamber through a nose air vent, and mouth-connecting room which is communicated with the lower air chamber through a mouth air vent. Hence, airflow can reach the mouth and the nose via separated paths, thereby preventing the disgusting exhalation and the spray breathed out from the mouth from reaching the nose, and obtaining more filtering area for the nose. The nose air vent has a valve allowing unidirectional airflow from the nose-connecting room to the upper air chamber.

Description

Breathing mask with shunt effect

The present invention relates to a respiratory mask, and more particularly to a respiratory mask having a shunting effect.

The existing air-purifying respiratory protection devices on the market include filter face breathing masks and mask type breathing masks, and do not include flat medical masks with poor adhesion. Their common shortcomings are: exhaling moist and hot gases, covering a large area and causing a sultry sensation; the bad breath exhaled by the mouth is confined within the hood, such as by talking or sneezing. The disadvantages are that, in terms of the filter face breathing apparatus, the wear tightness is slightly insufficient, and the use cost is high for the disposable type; in the case of the mask type breathing mask, the exhaled exhaust gas is limited to the inside of the cover body and the tidal volume is required to be vigorously breathed. When a high workload requires high volley, the wear is high and the outside air is difficult to leak into the high spirometry demand that cannot provide a high workload. The speech cannot be heard clearly, and the cumbersome and urgent discomfort is difficult. For a long time, there is trouble with cleaning and maintenance.

Take a clean air breathing apparatus as an example, mainly by adding an exhalation valve. Reduce the exhalation resistance and sultry feeling, and increase the willingness to use. This improvement has seen many similar products in the market. For example, the Republic of China Patent No. M490882 "Modification of Mask Structure" patent case, however, because it has the disadvantage of being contaminated by foam spray, it is often discarded before its filtration effect has been reduced to unbearable use; Air valves increase costs, making the same abandonment frequency more costly.

For the common shortcomings of the above-mentioned clean air breathing apparatus, there have been some new improvements, which are briefly described as follows: A mask structure with a transverse middle compartment, mainly providing two separate breathing spaces for the nose and the mouth, for example: Zhonghua The Patent Case No. M258752 of the Republic of China on the "mask structure with a compartment" claims that the bacteria generated by coughing can not be directly inhaled from the nose by means of a compartment device.

In another similar type, a flat mask is provided with a partitioning flexible strip which is curvedly placed between the nose and the mouth of the user to block the airflow generated by the nose and the mouth, for example, the Republic of China Patent No. M322822 The patent case for the "nose-nose-separated mask" or the patent case of the Republic of China Patent No. M477896 "mask structure with adjustable compartment" claims that it can adjust the position of the adhesive itself, can change the position against the face to increase comfort, and improve the aforementioned In case No. M258752, the fixed partition cannot adjust the position to accommodate the disadvantages of different users' faces.

These new cognitive masks have the disadvantages of unhygienic and uncomfortable communication in the mouth and nose chambers. Although the improvement is not bad, the market has not seen the related products, and it may be difficult to implement in its structure. There are two common disadvantages of the three, one of which is the addition of points. After the device is separated, the mask body is distorted and deformed, so that a larger gap is formed between the mask body and the face surface, and the leakage of pollutants from the gap is greatly reduced, and the protection efficiency is greatly reduced; the second is that the filter area is greatly reduced after the two halves are separated, causing breathing The impedance is increased and the breathing is laborious.

Another type of mask covers only the nose, and the activated carbon filter material is detachably disposed in the mounting hole on the mask. For example, the patent of the "Sports Mask" of the Republic of China Patent No. M469926 is mainly for the user to avoid during exercise. Inhaled dirty air and can achieve dryness on the cheeks. It can improve the disadvantages of sultry breathing protection. However, its filter material is directly placed on the nasal mask cup, and the filter material has only a small nostril size, and the filter area is too small, resulting in a disadvantage of large respiratory resistance.

For example, in the case of the Republic of China Patent Application No. 104110023, "A nasal mask-type respiratory protective device with a filtering sputum", the mask body covers only the nose, and has a filtering area with a large filtering area, which can be inserted and removed. The outer cover connected to the mask body improves the disadvantage that the filtration area is too small in the case of the above-mentioned No. M469926, and also improves the common disadvantage of the above-mentioned clean air breathing apparatus. However, this new type has a controversy, that is, the lack of protection of the mouth, although the protection of the mouth can be achieved by closing the mouth, but there is still doubt that the pollutants enter the mouth when speaking, there is still room for improvement.

Accordingly, it is an object of the present invention to provide a respiratory mask having a shunting effect capable of isolating aversive components and mouth foam exhaled by the mouth.

Thus, the novel respiratory mask having a shunting effect is suitable for being worn on a person's face and isolating the mouth and the nose. The breathing mask comprises: a mask member, a partition member, a filter module, and a hanging order yuan.

The mask member surrounds the mouth and nose and includes an inner surface facing the face and an outer surface opposite the inner surface.

The partition member includes a partition plate having a shape of a plate and an edge connecting the inner surface of the mask member, the partition having an abutting portion formed at one end and in contact with the face between the mouth portion and the nose portion, the partition plate and the partition The mask member and the face jointly define a lower air chamber that is separated from the upper and lower portions and is opposite to the upper air chamber and the opposite air portion.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 1, 2 and 3, a first embodiment of the present invention has a shunting effect. The first embodiment is suitable for wearing on a person's face and isolating the mouth and the nose. The breathing mask comprises: a mask member 1. A partition 2, a valve unit 3, a filter module 4, and a hanging unit 5.

The mask member 1 surrounds the mouth portion and the nose portion, and includes an inner surface 11 facing the face, an outer surface 12 opposite to the inner surface 11, an upper ring portion 13 formed in the upper half, and formed under the nose portion 13 a half portion and a partition 11 defined by the partition member 2 The lower ring portion 15. The upper ring portion 13 has an exhaust port 131 extending through the inner surface 11 and the outer surface 12.

The partition member 2 includes a partition plate 21 formed of a plate and having an edge connected to the inner surface 11 of the mask member 1, a shutter 22 adjoining the partition plate 21 and extending downward, and a nose portion penetrating the partition plate 21 The vent 23 and a mouth vent 26 penetrating the shutter 22. The partition plate 21 has an abutting portion 211 formed at one end and in contact with the face between the mouth portion and the nose portion. The partition plate 21 separates the mask member 1 to form the upper ring portion 13 and the lower ring portion 15. The shutter 22 has an inner panel surface 221 facing the face, an outer panel surface 222 opposite to the inner panel surface 221, and an extension portion 223 adjacent to the abutting portion 211. In the present embodiment, the abutting portion 211 has an arcuate shape toward the face. The shutter 22 and its extension 223 are spaced apart from the partition 21 by a distance. The partition 21, the upper portion 13 of the mask member 1 and the face together define an upper air chamber 24 opposite to the nose, due to the partition between the partition member 1 and the side of the partition member 2 opposite the outer panel surface 222 The venting portion 14 is formed to disappear, so that the visor 22 is exposed, and the inner surface 221 of the visor 22 and the lower ring portion 15 and the face of the mask member 1 together define an opposite mouth portion and The upper air chamber 24 separates one lower air chamber 25 that is not in communication with each other. The outer surface 222 of the shutter 22 is part of the outer surface 12 of the ring portion 15 below the mask member 1.

The valve unit 3 includes a valve member 31 disposed on the ring portion 13 of the mask member 1 with respect to the exhaust port 131 and allowing only airflow from the upper air chamber 24 to the outside, and is disposed opposite to the nose vent 23 The partition 21 and only allows airflow from the mask member The other valve member 32 of the venting portion 14 of the 1 flows toward the upper plenum 24. The valve member 31 has a plurality of grids 311 formed on the exhaust port 131, and a diaphragm 312 covering the outer surface 12 of the mask member 1 and covering the exhaust port 131. The diaphragm 312 has a fixed portion 3121 fixed to the ring portion 13 of the mask member 1 or the grid 311, and a movable portion 3122 that can be pushed by the airflow to open the exhaust port 131. The valve member 32 has a plurality of grids 321 formed on the nasal vents 23, and a diaphragm 322 on the side of the partition 21 opposite the upper air chamber 24 and covering the nasal vents 23. The diaphragm 322 has a fixed portion 3221 fixed to the partition 21 or the grid 321 and a movable portion 3222 that can be pushed by the airflow to open the nasal vent 23.

The filter module 4 is coupled to the outer surface 12 of the mask member 1 and includes a base unit 41, a filter unit 43 removably coupled to the base unit 41 and defining a chamber unit 42, and A barrier 44.

In the present embodiment, the base unit 41 has a seat body 411, and an oral exhalation port 412 formed on one side of the seat body 411, and a detachable closure opposite the mouth exhalation port 412. A closure member 413.

In the present embodiment, the portion of the permeable portion 14 that is overlapped by the chamber unit 42 becomes part of the chamber unit 42.

In the present embodiment, the filter unit 43 has a filter member 431. The filter member 431 defines the chamber unit 42 together with the base body 411, and has a bracket 4311 detachably coupled to the base body 411, and is attached to the bracket 4311 and attached thereto. Airflow enters and exits a filter material 4312 of the chamber unit 42. The filter material 4312 can be a flat screen, or a pleated screen, or a foam filter, or a bag filter, or a multilayer or composite filter.

The barrier member 44 is formed between the seat body 411, the filter member 431 and the outer surface 12 of the lower ring portion 15 of the mask member 1, and the chamber unit 42 is partitioned to form a through-nozzle space 421 and a port space. 422. The nasal passage space 421 communicates with the upper air chamber 24 through the nasal vent 23 . The port space 422 communicates with the lower air chamber 25 through the port vent 26 and communicates with the port exhalation port 412.

The hanging unit 5 is disposed on the mask member 1 or the seat body 411 of the filter module 4. In the embodiment, the hanging unit 5 includes two straps 51 for positioning the mask member 1 In the face of people.

Referring to Figures 4, 5, and 6, when a person inhales a mouth or nose, an external airflow enters the chamber unit 42 through the filter material 4312 of the filter member 431. At this point, the airflow will be separated by the barriers 44 to form a two-way split.

One of the shunts flows from the nasal passage 421 toward the nasal vent 23 of the partition 2 and pushes the movable portion 3222 of the diaphragm 322 to move the movable portion 3222 of the diaphragm 322 away from the partition 21 The nose vent 23 is opened in a direction opposite to one side of the upper air chamber 24. Thereby, the inhaled airflow is passed through the nasal vent 23 into the upper plenum 24, providing the nasal inhalation required by the person.

When a person inhales through the nose, a negative pressure is generated in the upper air chamber 24, attracting The diaphragm 312 on the exhaust port 131 of the spacer 1 is in close contact to close the exhaust port 131. When there is no breathing airflow, the diaphragm 312 of the exhaust port 131 is elastically deformed to close the exhaust port 131.

Another shunt enters the lower plenum 25 from the vent vent 26 of the louver 22 of the partition 2 through the venting space 422, thereby providing the inhaled airflow to the mouth of the person. need.

When a person exhales through the nose, the exhaled airflow may be blocked by the partition 21 of the partition member 2, and the diaphragm 322 closing the nasal vent 23, so that the airflow cannot flow into the nasal passage space 421. It can only flow toward the exhaust port 131 of the mask member 1 and push the movable portion 3122 of the diaphragm 312 to move the movable portion 3122 of the diaphragm 312 away from the exhaust port 131 of the mask member 1, and The exhaust port 131 is opened. Thereby, the exhaled airflow is discharged through the exhaust port 131 to the upper air chamber 24.

When a person exhales through the mouth, the exhaled airflow enters the opening space 422 through the mouth vent 26 due to being blocked by the partition 21 and the shutter 22 of the partition 2, and is blocked by the barriers. In the case of 44, the outside of the filter medium 4312 is discharged. Thereby, the exhaled airflow is not communicated with the nasal passage space 421, and the aversive component and the mouth foam exhaled by the mouth are isolated.

It should be noted that during use, the mouthpieces 412 may also be opened and the mouthpieces 412 may be opened. At this time, the airflow exhaled by the mouth may pass through the mouthpiece 422 through the mouthpieces. 412 is directly discharged to the outside without passing through the filter 4312. Thereby, the arrangement of the oral exhalation ports 412 can greatly increase the amount of breathing by means of the nasal inhalation, and is suitable for a wearer who has a high amount of exercise or a large workload and needs a large amount of breathing. In addition, when the mouth exhalation port 412 is opened, the voice of the wearer can also be transmitted through the mouth exhalation port 412, thereby improving the clarity of the sound during communication, and since the mouth is still mostly Since the mask member 1 is surrounded by the partition member 2, the probability that dirty air enters the mouth portion during speaking can be greatly reduced.

Referring to Figure 7, the first embodiment further includes a detecting member 6. In the embodiment, the detecting member 6 is an elastically deformable material. The detecting member 6 is detachably coupled to the base 411 before the filter member 431 (see FIG. 4) is not coupled to the base 411. There may be two functions, one of which is to replace the filter member 431 and to close the ventilation at the position, and the other function is convex or concavely deformed by the air pressure difference.

When the wear-resistance detection is performed, the user wears the respiratory mask, combines the detecting member 6 with the body 411, and closes other vent holes such as the exhaust port 131 and the like. The wearer uses the exhalation to create a positive pressure, the inhalation to create a negative pressure, and the elastically deformable material property, so that the detecting member 6 can be concave when inhaling and protrude when exhaling, if concave or If the protrusion can last for a few seconds, it is determined that the respiratory mask passes the detection, and the wear is closed without air leakage, and vice versa, the wear does not close and the leakage occurs.

Referring to Figure 8, a second embodiment of the present invention is substantially the same as the first embodiment, with the following differences: The partition 2 omits the extension 223 of the shutter 22 as shown in FIG. The shutter 22 is directly connected to the partition 21 and extends downward. Thereby, the partition plate 21 can also be in contact with the face between the mouth portion and the nose portion by the abutting portion 211 at one end. And the partition 21, the upper ring portion 13 of the spacer 1 and the face jointly define an upper air chamber 24 opposite to the nose, the inner surface 221 of the shutter 22 and the lower ring portion 15 and the face of the spacer 1 A lower plenum 25 that is opposite the mouth and that is not in communication with the upper and lower separations of the upper plenum 24 is collectively defined. It should be noted that the nasal vent 23 may also be disposed in the upper ring portion 13 (not shown) to communicate the upper air chamber 24 and the nasal space 421.

The second split is directly passed through the filter material 72 of the mask member 7 and the filter portion 713 at the opposite position, and directly enters the front air chamber 27, and passes through the partition member 2 The nasal vent 23 enters the upper plenum 24 and also provides the nasal insufflation required by the person's nose, in such a way that the area filtered through is greatly increased to reduce the inspiratory impedance.

The third split flow is directly passed through the filter material 72 of the mask member 7 and the filter portion 713 at the opposite position, and directly enters the lower air chamber 24, thereby providing the mouth for the person to inhale.

When a person exhales through the nose, the exhaled airflow will be directly discharged from the opposite position of the filter portion 713 due to being blocked by the partition 21 of the partition member 2 and the valve unit 3, thereby exhaling the exhalation. The volume of the exhaust gas is greatly reduced to reduce the amount of respiratory tidal volume. When a person exhales through the mouth, the exhaled airflow is directly discharged from the opposite portion of the filter portion 713 to the outside due to being blocked by the partition 21 and the shutter 22 of the partition member 2. Thereby, the exhaled airflows are not connected to each other, and the aversive components and mouth foam exhaled by the mouth are isolated.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. With the special structural design of the new model, the respiratory airway between the nose and the mouth can be separated, the area of the exhaled gas covering the face can be reduced, and the feeling of stuffiness can be reduced, and the nose does not suck the gas or the mouth foam. The stench of the odor improves wear comfort.

2. The valve unit 3 is disposed on the nasal vent 23 adjacent to the upper air chamber 24 and the exhaust port 131, so that the gas can flow in one direction, and the exhaled gas is confined in the upper air chamber 24. In this way, it is possible to reduce the tidal volume and make the breathing more labor-saving than the general clean air breathing protection.

3. The filtering module 4 can enlarge the filtering area of the filtering unit 43 and distribute a larger filtering area by the blocking member 42 to the nose space 421 compared to the opening space 422 to make the nose breathe more. To save effort, this is not possible with the mask member 1 alone and without the filter module 4.

4. When the nasal vent 23 is disposed on the side of the partition 21 opposite to the upper air chamber 24, the diaphragm 322 can close the nasal vent 23 by gravity or a slight elastic deformation tension. Therefore, the user can open the nasal vent 23 by inhaling the negative pressure of the upper upper air chamber 24. This smaller diaphragm 322 is elastically deformable and can be more clearly distinguished from the larger tension when the nose vent 132 is disposed on the upper air chamber 24 side of the upper ring portion 13. By the elastic deformation of the small diaphragm 322, the user can inhale more effortlessly, and can also prevent the function of exhaling air through the nasal vent.

5. When the abutting portion 211 is in the shape of a curved plate, it has a large contact area with the face, and is comfortable to wear. When the abutting portion 211 constitutes the end edge of the partition 21 and the partition When the sheet 21 is in the shape of a flat plate, it has a small contact area with the face, and although it has a stinging feeling with respect to the arc-shaped abutting portion 211, it can still achieve the purpose of blocking and shunting.

6. By designing the mouth exhalation ports 412, the mouthpiece breathing of the nasal mouth can be performed, the breathing amount is greatly increased, and the sound can be transmitted through the mouth exhalation ports 412, and the sound of the communication is improved. Sharpness.

7. The new type of consumables only has the filter material 4312, and the filter material 4312 can be used in combination with different performance materials. Because the filter material 4312 is used at a lower cost, the present invention can be reused rather than discarded, and used for a long time. The cost is lower.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
