Description

Hygiene mask {Hygienic mask}

The present invention relates to a method and apparatus for dispensing foreign substances in the mouth due to conversation or coughing at work in a service industry employee who faces a customer face to face with a customer including a foodservice business, The sanitary mask has been widely used in recent years as an application for preventing the dust from entering into the other party or food.

Employees and doctors of food service shops such as restaurants, butchers, and marts wear sanitary shields to prevent saliva, such as saliva discharged from the mouth, from contaminating the customer's body during conversation when contacting the customer. These shielding parts are made of an inexpensive disposable shielding material made of an inexpensive material such as nonwoven fabric in consideration of the convenience of wearing and the convenience of washing. However, since these products are manufactured mainly for air filtering performance, If you wear it, you will not be able to ventilate properly. As a result, it will cause fatigue when you use it for a long time due to the delay of carbon dioxide emission. Also, it avoids wearing hot and frustrating clothes. Especially, Further, the shielding portion interferes with communication with the customer and interferes with conversation, and the general nonwoven fabric shielding portion has many problems as a sanitary mask for shielding saliva from the mouth.

In order to solve such a problem, a transparent plastic sanitary mask using a transparent plastic mouth window has recently been developed and used in the food industry such as a mart or a restaurant. Patent No. 10-2011-0103985 Shielding portion "shows a technical structure in which the lid shielding film 30 formed of a transparent plastic film is tightly bonded to the shielding body 30 by the jaw support 20.

Unlike the conventional nonwoven fabric shielding unit, the clear plastic mouthshielding unit has a space for an air passage between the mouthwear film and the mouth to improve the fit feeling. The contact area between the shielding unit and the face is small, The transparent plastic sanitary mask has been widely used in the domestic market, such as Korea, Japan, Korea, Japan, Korea, Japan, etc. In recent years, It has become almost a necessity for employees engaged in customer service department of food service industry such as food store of department store, hotel, buffet, restaurant.

However, since the plastic transparent sanitary mask has disadvantages due to the increase in the number of users, there is an increasing demand for improvement by users. The present invention improves the problem of the conventional transparent plastic lid shielding, The shielding film does not interfere with the conversation, and the jaws and ears are comfortable at the time of conversation, and the ejected objects such as saliva are easily removed without being conspicuous.

As shown in FIG. 1, the conventional transparent sanitary mask includes a shielding frame 1 having a substantially semicircular curvature, a shielding frame 1 which is adhered to the shielding frame and shields foreign substances from the wearer's mouth (2), a jaw support base (3) attached to the shield frame to support the shield at the jaw, and a handle (4) attached to both ends of the shield frame to attach the shield frame to the face do.

First, the needles and foreign substances discharged from the mouth of the user at the time of the conversation appear to be dirty to the transparent lining film. Second, the lining film is made of PET or PC It is a plastic resin film of plastic, which is an obstacle to obstruct the sound waves, so it is inconvenient to use the shield to talk. Third, since the lid film can not transmit air at all, The transparent sanitary mask is severely moved during the conversation because the movement of the jaw is transmitted to the shield in the dialogue due to the fact that the transparent sanitary mask is fixed to the lower jaw part and the ear, .

First, when a user wears a shield and talks, the user's saliva and foreign substances in his or her mouth are discharged and attached to the lid film, Because it looks like spitting, it causes discomfort to the customer, and the wearer who wears it often wipes the liner film with the washer fluid and wash water gun. This is a very troublesome operation. These dried extrusions are removed well at first, but if the washings are repeated, the dirt will not stick to the liner film and will not be removed well, so the clear liner film will become dirty over time and will repeat every time I think the cleaning process is troublesome and annoying. Thereby avoiding the wear of the transparent sanitary mask.

Second, since the lipped film located in front of the user's mouth is made of PET or PC, it interferes with the transmission of sound waves and becomes an obstacle to reflect sound waves. Therefore, when the user uses a shielding part and talks, Since it is transmitted only by the diffraction of the sound, the transmission rate of the voice is lowered. In order to increase the voice transmission rate, it is necessary to raise the volume at the time of conversation, which causes a considerable physical burden to the user, which causes the user to slant the transparent sanitary mask at the time of conversation or to take it off altogether. If these things happen repeatedly, the user will not be able to use the transparent hygiene mask for the original purpose by wearing the transparent hygiene mask instead of wearing it in the mouth.

Third, since the mouth masking film of the transparent sanitary mask has a structure that is separated from the nose and the mouth to some extent, it blocks the breathing rather than the existing nonwoven fabric shielding but becomes an obstacle to completely block the flow of breathing air. The flow of breathing air is still unreliable. Particularly, due to the lining film, hot and humid exhaust air can not be discharged directly out of the shield, and it is kept in the shield, so that it is hot in summer and moisture penetrates into the mouth, and the lower part of the chin is always sweaty and damp, Therefore, many users at marts, etc. may cause the transparent hygiene mask to be removed or hang over the neck.

Fourthly, the transparent sanitary mask is firmly fixed to the lower jaw by the jaw support and jaw pads, and has a structure in which it is fixed firmly to the face by catching on the ear by the handles. However, when the wearer has a conversation, the lower jaw moves to the upper and lower sides, and at this time, the transparent hygiene mask fixed to the lower jaw moves to the upper, lower and left sides according to the movement of the lower jaw. In the case of users, such as a busy word-of-mouth function, transparent hygiene masks are often shaken, which often distracts the customer's eyes and confuses the customer.

On the other hand, whenever the wearer speaks, the change in the distance between the jaw and the ears causes repeated expansion and contraction of the earbuds, resulting in a change in the pressure applied to the ear, resulting in repeated irregular loads on the jaw muscles. Such a load increases the wearer's fatigue when the elasticity of the earbuds is small. In order to solve this problem, in the past, a method of keeping the elasticity of the hand as smooth as possible has been sought. However, the handles with soft elasticity can not withstand the weight and repeated load of the transparent sanitary mask easily, and they are easily stretched, or the elasticity is completely lost due to the repeated expansion and contraction. Therefore, a large number of users can use the transparent sanitary mask Causing the ear to hang.

In order to solve the problems of the prior art as described above, the present invention has been made in order to solve the problems of the prior art, Provides a sanitary mask that does not interfere with the conversation and comforts the chin and ears during conversation.

Specific details for carrying out the invention are described on the basis of practical examples. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept as defined by the appended claims. The present invention is not limited to the following embodiments.

(Example 1)

This embodiment is a sanitary mask. The sanitary mask means that the foreign matter discharged from the user is prevented from splashing out. Here, a foreign object refers to a substance discharged from a user, such as a saliva discharged from a user's mouth when a user coughs or talks. To prevent such foreign matter from splashing out, it means to prevent foreign matter from being polluted to external bodies such as the body and food of the others. As shown in FIG. 2, the sanitary mask according to the present embodiment includes a frame 10 and a shielding portion 20. In addition, the sanitary mask of the present embodiment may further include the breathable filter 30, the support portion 40, the contact portion 50, and the hook portion 60.

The frame (10) supports the shield (20). Accordingly, when the sanitary mask is worn, the shielding portion 20 is arranged to shield the user's face, thereby preventing the foreign matter discharged from the user from splashing to the outside.

The frame 10 preferably has excellent mechanical strength, durability and elasticity because it supports the ventilation filter 30, the support portion 40 and the contact portion 50 and the hook portion 60 as well as the shield portion 20 . In addition, the frame 10 is preferably made of resin such as ABS (acrylonitrile-butadiene-styrene) or PC (polycarbonate) excellent in mechanical porosity for mass productivity. The frame 10 has an approximately semicircular shape so as to surround the user's face in the jaw portion, and ergonomically forms a shape that fits the face.

At the center of the frame 10, as shown in FIG. 2, a pair of shield fixing projections 11 may be formed. This shield fixing protrusion 11 is inserted into the shield fixing hole 21 formed in the shield 20 and then inserted into the insertion groove 41 of the support 40 so that the frame 10 is shielded The portion 20 and the support portion 40 can be integrally fixed together.

As shown in Figs. 2 to 4, a pair of hooking grooves 15 may be provided at left and right ends of the frame 10, for example. The hook portion (60) is inserted and fixed in the hook groove (15). The insertion hole 16 may be formed in the hook groove 15 so as to be opened in the direction of the shielding portion fixing protrusion 11. It is possible to easily attach and detach the hooking part 60 to the hooking groove 15 through the insertion hole 16. In addition, the insertion hole 16 is formed to be thinner than the strap 65 constituting the latching portion 60, so that the latching strap 65 once inserted into the latching groove 15 can be prevented from being easily released.

A pair of shield side surface fixing projections 12 may be formed on the left and right sides of the insertion hole 16 of the frame 10. [ The side edge of the lower end of the shielding portion 20 is stably fixed to the frame 10 by engaging the frame engaging groove 25 formed at the side end of the lower end of the shielding portion 20 .

A filter side fixing protrusion 13 for fixing the side surface of the air-permeable filter may be formed between the shield side surface fixing protrusion 12 of the frame 10 and the shield fixing protrusion 11. The filter side surface fixing hole 33 formed in the air permeable filter 30 is coupled to the filter side surface fixing protrusion 13 so that the air permeable filter 30 can be firmly fixed to the frame 10. The filter side coupling hole 33 is formed to be narrow in the lower side and wider in the upper side, and is preferably formed to be difficult to be removed once it is inserted.

At the lower end of the frame 10, a structure reinforcing protrusion 19 projecting vertically rearward from the body of the frame 10 may be formed. It is preferable that the structure reinforcing projection 19 is made thin and light as the H-shaped steel so that appropriate strength and elasticity can be maintained while attaching various functional parts.

The shield 20 extends away from the user's face when the sanitary mask is worn and shields the user's face. As a result, foreign substances such as saliva discharged from the user can be prevented from splashing to the outside.

The shielding portion 20 is made of polycarbonate (PC) or poly (ethylene terephthalate) film so that it is thin and light and can secure transparency. Furthermore, the shielding portion 20 can improve the hygiene by applying antimicrobial treatment or anti-fog coating.

The shield 20 may be formed in a substantially semicircular or trapezoidal shape, for example, as shown in Fig.

As shown in FIG. 5 by way of example, the shielding portion 20 is provided with a ventilation portion 27 through which air to be breathed by the user can pass. Accordingly, when the sanitary mask is worn, the user's breathing air can smoothly communicate with the outside or the user's voice can be smoothly transmitted to the outside. When the user smoothly communicates with the outside from the inside of the sanitary mask, the moisture generated by the respiratory air can be prevented from being generated in the frame 10 or the shield 20, So that it is possible to prevent the user from feeling frustrated. In addition, the shielding portion 20 may be provided with a shielding portion fixing hole 21 or a frame engagement groove 25. The shield 20 can be firmly fixed to the frame 10 by the shield fixing holes 21 and the frame engagement grooves 25.

The ventilation portion 27 may include at least one through hole having a coarse size. For example, the ventilation part 27 may be formed of one through hole having a coarse size. In this case, the breath air of the user or the voice of the user can be communicated very smoothly to the outside. In this case, as shown in Fig. 5 as an example, the upper and lower portions of the center of the through-holes formed in an elliptic shape are excessively separated by providing the through-hole support portion 26 in the middle of the through hole to prevent the shape of the through hole from being distorted can do. When the through hole is small, it is not necessary to provide the through hole support portion 26.

The ventilation portion 27 may include a plurality of through holes having a small size although not shown in the figure. Accordingly, when the sanitary mask is worn, the user's breathing air can smoothly communicate with the outside, or the voice of the user can be smoothly transmitted to the outside. In addition, foreign matters such as saliva discharged from the mouth, So that it is possible to suppress splashing to the outside. In this case, each size of the fine holes can be made to be a very small diameter of 1 mm or less as long as the user's breathing or conversation can be smoothly performed by the entire fine holes.

The ventilation portion 27 may be formed by cutting a side portion of the shielding portion 20 that is coupled to the frame 10, though it is not shown in the figure. In this case, the ventilating portion 27 has a shape of a recess in the side portion of the shield 20 coupled to the frame 10, not the shape of the hole. Such concave portions may be formed in plural. The concave ventilation portion 27 forms the shape of the hole when it is combined with the frame 10. The ventilation portion 27 having a concave shape can be manufactured more easily than the ventilation portion 27 having the hole shape.

The ventilation part 27 may be formed at various positions of the shield 20 where the user's breathing or conversation can be smoothly performed. However, the ventilation part 27 may be formed at a position corresponding to the user's mouth or nose when the sanitary mask is worn The user's breathing and conversation can be induced more smoothly.

The shield fixing holes 21 may be formed at the lower end of the shield 20 in pairs. The shield fixing protrusion 11 of the frame 10 can be inserted into the shield fixing hole 21. This shielding fixing hole 21 enables the shielding portion 20 to be firmly fixed to the frame 10.

The frame engagement grooves 25 may be formed in pairs on the right and left ends of the shield 20, one by one. The shielding side surface fixing projections 12 of the frame 10 can be inserted into the frame engagement grooves 25. The frame 20 can be firmly fixed to the frame 10 by the frame engagement grooves 25.

The air-permeable filter 30 covers the ventilation portion 27 of the shield 20 and is capable of passing air therethrough. Accordingly, it is possible to prevent foreign substances discharged from the user from splashing through the ventilation part 27 when the sanitary mask is worn. Particularly, in the case where the ventilation portion 27 is large and the possibility that the foreign matter discharged from the user is likely to bounce out through the ventilation portion 27 is high, It is more effective to prevent foreign substances from the user from splashing out through the ventilation portion 27 while allowing the user's voice to be smoothly transmitted to the outside.

The air-permeable filter 30 may be made of a material capable of passing air such as a nonwoven fabric. Or the air-permeable filter 30 may be formed of a film having a plurality of fine holes formed therein, air-permeable paper, or the like. The air-permeable filter 30 is preferably made of a material having the highest air permeability as far as it does not allow foreign substances discharged from the user to pass therethrough.

The breathable filter 30 is preferably thin and light, having a strength to withstand the speed and force with which the user breathes air.

The air-permeable filter 30 may have a vent portion having a smaller size than the ventilation portion 27. Thus, the foreign substance of the user, which can be discharged to the outside through the ventilation part 27, can be prevented from being discharged to the outside.

The breathable filter 30 may be coupled to the frame 10 or the shield 20 to be replaceable. Thus, by replacing the air-permeable filter 30 contaminated with the user's foreign material with the clean air-permeable filter 30 according to the use for a long time, hygiene of the sanitary mask can be easily maintained. When the breathable filter 30 can be replaced as described above, the breathable filter 30 is made of a low-cost material, so that the breathable filter 30 contaminated can be replaced with a clean breathable filter 30 at low cost . Also, according to the use of the sanitary mask, foreign substances remaining in the sanitary mask can be easily removed.

The air-permeable filter 30 may have a size and shape to cover the ventilation portion 27. For example, the air-permeable filter 30 may be formed in a semicircular or trapezoidal shape so as to cover the ventilating portion 27. It is preferred that the breathable filter 30 be sized to cover the ventilation portion 27, but having a size smaller than the shielding portion 20 may be provided to the outside of the breathing air of the user, It is preferable not to disturb delivery.

The breathable filter 30 may be provided on the side facing the user of the shield 20. Accordingly, when the sanitary mask is worn by the user, even if the breathable filter 30 is subjected to a force directed toward the outside of the user due to respiration or conversation, it is separated from the shielding portion 20 by being supported by the shielding portion 20, It is possible to easily prevent deviations. However, the air-permeable filter 30 is not limited to this, and may be provided on the side of the shield 20 facing the outside of the user, if necessary.

The breathable filter 30 may be integrally or detachably coupled to the shield 20. Likewise, the breathable filter 30 can be integrally coupled to the frame 10 or detachably coupled thereto. For example, as shown in FIG. 6, a pair of filter binding portions 31 are formed at the center of the breathable filter 30, and by inserting the shielding portion fixing projections 11 of the frame 10 , The breathable filter 30 can be detachably coupled to the frame 10. At this time, the filter binding portion 31 may be in the form of a through-hole for completely passing the shielding fixing projections 11, or may be formed in a slot shape which can be easily fitted into the shielding portion fixing projections 11 by sliding them from top to bottom.

As shown in FIG. 6, a pair of filter side coupling holes 33 may be further formed on both sides of the breathable filter 30. Both side portions of the ventilation filter 30 can be firmly fixed to the frame 10 by fitting the filter side fixing projections 13 of the frame 10 to the filter side fitting holes 33. [ It is preferable that the filter side fixing protrusions 13 are formed so that the top side is wide and the bottom side is narrow so that it is difficult to be detached after being once inserted into the filter side coupling hole 33. [

The support portion 40 supports the frame 10 to the user when the sanitary mask is worn. Thus, when the sanitary mask is worn, the frame 10 can be stably supported by the user.

The supporting portion 40 may be made of a resin material such as ABS (acrylonitrile-butadiene-styrene) having excellent elasticity, rigidity and workability.

The support portion 40 includes a pair of fastening portions 40 projecting in parallel to the front side of the user so as to keep the frame 10 at a predetermined gap with respect to the user while being coupled to the frame 10, And a column 43 may be provided. However, the fixing post 43 may be composed of one or more than three. An insertion slot 41 is formed at the front end of the fixed post 43 so that the shield fixing protrusion 11 of the frame 10 is inserted. Whereby the frame 10 can be coupled to the fixing post 43 and can be arranged at a predetermined interval on the user's face surface when the sanitary mask is worn.

At the rear end of the fixing post 43, the upper receiving portion 44 is provided so as to extend in a direction crossing the fixing post 43, so that the upper portion of the user's jaw can be supported. A lower receiving portion 42 extending downward from the lower portion of the fixed column 43 to have a shape like a "J " is coupled to the lower receiving portion 44 to support the lower portion of the user's jaw.

The frame 10 can be arranged to be spaced apart from the user by the fixed post 43 and the upper and lower receiving portions 44 and 42 so that the frame 10 can be stably supported by the user. Furthermore, the shield 20 coupled to the frame 10 can likewise be arranged to maintain a predetermined distance from the user and at the same time be stably supported by the user. However, the fixing post 43 and the upper and lower receiving portions 44 and 42 are not limited thereto and may have various other configurations that can support the frame 10 to the user when the sanitary mask is worn.

The contact portion 50 is coupled to the support portion 40 so as to include a portion remote from the support portion 40 and is brought into contact with the wearer when the sanitary mask is worn. Thus, the support portion 40 can support the sanitary mask without directly contacting the user, thereby allowing the user to wear the sanitary mask smoothly, thereby greatly improving the wearing comfort. Even when the contact portion 50 moves in accordance with the movement of the jaw during the user's conversation, the movement of the contact portion 50 is canceled by the elasticity of the contact portion 50, so that the movement of the frame 10 and the shield 20 coupled to the contact portion 50 Is greatly reduced. Therefore, the unstable feeling due to the movement of the sanitary mask can be greatly reduced to the user who is talking to the user.

The contact portion 50 may be made of various materials, but it is preferable that the contact portion 50 is made of an elastic material such as rubber because it can enhance the feeling of wearing comfortably.

The contact portion 50 may have various shapes including a portion apart from the support portion 40. For example, the contact portion 50 may be configured such that both ends are coupled to the support 40 and portions other than both ends are spaced apart to maintain a predetermined spacing in the support 40, as illustratively shown in Figures 7 and 8, It can have the same band shape as that of the band. 9, the upper bearing portion 44 of the support portion 40, which is the portion to which the contact portion 50 is engaged, is in contact with the contact portion 50, For example, a shape extending concavely along the curve of the face of the user. At this time, the contact portions 50 to which the left and right ends of the upper receiving portion 44 are coupled to the left and right ends, respectively, may be arranged in a flat shape. However, the contact portion 50 is not limited to the portion apart from the support portion 50, and may include various other configurations. For example, as shown in FIG. 10, a portion of the support portion 40 facing the contact portion 50 may be formed flat and a portion of the contact portion 50 facing the support portion 40 may be recessed have. The contact portion 50 facing the support portion 40 and the portion of the support portion 40 where the contact portion 50 faces is not shown in the figure so that the contact portion 50 includes the portion away from the support portion 50. [ Or all of the portions of the support portion 40 facing the support portion 40 and the portions of the contact portion 50 facing the contact portion 50 are all formed to be flat, And both end portions of at least one of the portions may be convexly formed.

The contact portion 50 may be detachably coupled to the support portion 40. [ Thereby, only the contact portion 50 can be separated separately for cleaning after replacement for a long period of time or for replacement due to breakage. In addition, the contact portion 50 needs to be stably fixed to the support portion 40 so that unwanted separation does not occur during use of the sanitary mask. For this purpose, for example, a band locking protrusion 55 is provided in the contact portion 50 such that a band catching groove is formed at the left end and right end, respectively, as shown in FIG. 8, The contact portion 50 can be stably fixed to the support portion 40 by being fixed to the band fixing protrusions 45 and the band fixing grooves 46 formed corresponding to the left and right ends of the upper receiving portion 43, Can be combined. Here, the band fixing groove 46 prevents the fixed contact portion 50 from deviating in the vertical direction, and the band fixing protrusion 45 prevents the contact portion 50 from deviating in the left-right direction. The band fixing protrusions 45 and the band fixing grooves 46 may be positioned on the same side as the contact portions 50 on the left and right ends of the upper receiving portion 43 of the support portion 40, So that the band stopper 55 of the contact portion 50 can not easily escape from the band fixing groove 46. However, the contact portion 50 is not limited thereto, and may have various other configurations that can be detachably coupled to the support portion 40. [

As shown in FIG. 11 by way of example, the contact portion 50 may further include a cover 48 made of a nonwoven fabric or a cloth material so as to surround the outer circumferential surface thereof. Accordingly, even if the skin sensitive user such as an atopic patient uses it or is used in a place where sweat is frequently used, it is possible to prevent adverse effects on the skin caused by the contact portion 50 or to absorb sweat.

By the double cushioning by the support portion 40 and the contact portion 50 as described above, the feeling of wearing of the sanitary mask is excellent, the contact area of the sanitary mask and the user is minimized, and the contact surface is made of a human- And a hygiene mask capable of absorbing sweat can be provided.

As shown in Figs. 2 to 4, the hook portions 60 are each formed of a pair of hooks 15 fixed at both ends of the frame 10, It becomes a fixed role.

The hook portion 60 may have a strap stopper 61 that binds the strap 65 and the strap 65 together. The hooking straps 65 may be made of a string having elasticity, and both end portions of the hooking straps 65 are bound by a strap stopper 61. [ Whereby the hooking strap 65 forms a ring. The ring-shaped hook piece 65 is inserted into the hook groove 15 formed in the frame 10 and fitted into the insertion hole 16 of the frame 10. Thus, the hook portion 60 coupled to the frame 10 allows the user to wear the frame 10 and the shield 20 coupled thereto by being caught by the user's ear. However, this hooking portion 60 is not limited to this, and may have various other configurations that can fix the frame 10 to the user.

(Example 2)

This embodiment relates to a sanitary mask. The sanitary mask of the present embodiment is characterized in that at least one ventilation part 111 is formed in the frame 110 for supporting the shielding part 120 so as to allow the user to breathe air. Accordingly, the flow of the user's breathing air or conversation voice is naturally guided to the outside, so that the user's breathing air or conversation voice can be smoothly communicated to the outside. The sanitary mask of the present embodiment may further include a breathable filter 130 in addition to the frame 110 and the shield 120 having the ventilation part 111 formed thereon.

When the ventilation part 111 is formed in the frame 110, the breathing air of the user or the conversation voice of the user can be more smoothly communicated to the outside through the frame 110 near the nose or mouth of the user.

In the frame 110, the ventilation part 111 can be formed in various sizes and numbers, but it is preferable that the ventilation part 111 is formed sufficiently large or sufficiently large. To this end, the frame 110 preferably increases its volume. For example, as shown in Figs. 13 and 14, the frame 110 can be formed to have a ventilation portion 111 at an increased vertical width by increasing its vertical width.

The ventilation part 111 may be variously formed on the frame 110. [ For example, as shown in FIGS. 13 and 14, the ventilating portion 111 may be formed by arranging a large-size ventilating portion 111 at the center of the frame 110 and centering the ventilating portion 111 toward the left and right The ventilation portion 111 having a small size can be arranged. As a result, the flow of the breathing air can smoothly communicate with the outside through the large ventilation part 111 of the central part close to the flow of the breathing air generated from the user's nose and mouth.

The shield 120 is coupled to the frame 110 to extend away from the user's face when the sanitary mask is worn, thereby shielding the user's face. The shielding portion 120 is coupled to the frame 110 so as not to block the ventilation portion 111 formed in the frame 110. For this purpose, it is preferable that the shielding part 120 is coupled to the upper part of the part where the ventilation part 111 of the frame 110 is formed.

The air-permeable filter 130 covers the ventilation part 111 formed in the frame 110 and prevents foreign substances generated during user's breathing or user's conversation from being discharged to the outside through the ventilation part 111 .

The air-permeable filter 130 is preferably arranged so as to cover the ventilation part 111 formed in the frame 110 and not cover the shielding part 120. This allows the breathable filter 130 not to obstruct the shield 120 so as not to interfere with the view through the shield 120.

The breathable filter 130 is preferably arranged on the face of the frame 110 facing the user so as to cover the ventilation part 111 of the frame 110. This makes it possible to prevent the breathable filter 130 from being detached from the frame 110 by the user's breathing air or conversation voice.

In addition, in the case of the sanitary mask of this embodiment, the same contents as those of the sanitary mask of the first embodiment are omitted.

(Example 3)

This embodiment relates to a sanitary mask. The sanitary mask of the present embodiment is characterized in that the shielding portion supported by the frame is made of a breathable material that allows air to breathe by the user. Accordingly, it is not necessary to provide a ventilation part that allows the user to breathe air separately through the frame or the shielding part, so that the breathing air or the conversation voice of the user can be smoothly communicated to the outside through the shielding part, The configuration of the second embodiment is simplified.

The shielding portion is made of a breathable material, but preferably has a predetermined rigidity so as to be supported by the shielding portion.

Preferably, the frame further includes at least one ventilation portion capable of passing air through which the user breathe. Accordingly, the breathing air or the conversation voice of the user can be communicated to the outside through the ventilation part of the frame as well as the shielding part of the breathable material, so that communication of the user's breathing air or conversation voice to the outside can be greatly improved.

More preferably, it may further comprise a ventilation filter covering at least one ventilation part formed in the frame. As a result, it is possible to prevent foreign matter, which is generated during user's breathing or user's conversation, from being discharged to the outside through the ventilation part of the frame.
