[0001] This application is a divisional application of the invention patent application with application number 202110451131.1 submitted to the China Patent Office, application date April 26, 2021, and the invention name is "A drug storage chamber for masks, pharmaceutical tablets and new masks". Technical Field

[0002] The present invention relates to the field of wearable respiratory protection products, in particular to a pharmaceutical tablet. Background Art

[0003] In the field of respiratory protection products, it is well known that different types of masks, such as medical masks, activated carbon adsorption masks, and N95 dust protection masks, are used to protect the human respiratory system. In the process of researching and implementing human respiratory protection, researchers have found that masks in the existing technology have at least the following problems: The protection principle of most masks is passive protection, that is, the mask structure uses layers of filtering materials to perform adsorption-type filtration on harmful substances such as germs, dust, PM2.5 in the air, but cannot provide active protection such as killing germs in the air.

[0004] In view of this, it is necessary to develop a pharmaceutical tablet to solve the above problems. Summary of the Invention

[0005] In order to overcome the problems existing in traditional masks, the technical problem to be solved by the present invention is to provide a pharmaceutical tablet that can effectively inactivate pathogens such as the currently prevalent influenza A H1N1 virus and GX_P2V coronavirus, thereby effectively inactivating pathogens while adsorbing and filtering harmful substances such as pathogens, dust, PM2.5 in the air. As for the pharmaceutical tablet, the present invention provides a pharmaceutical tablet to solve the above technical problems. The pharmaceutical tablet is placed in the drug storage chamber as described in any of the above items, so that its volatile components are emitted outward through the breathable mesh on the bottom wall, which can achieve the effect of inactivating viruses. In terms of mass percentage, the pharmaceutical tablet is made of the following raw materials: Menthol 5~40wt%; Borneol 5~25wt%; Camphor 8-15wt%; Eucalyptus oil 10~50wt%; Wintergreen oil 2~10wt%; Turpentine 5~10wt%; Clove oil 1~5wt%; Orange peel 1~3.5wt%; Bergamot 0.5~2.1wt%.

[0006] The technical solution in the above technical solution has the following advantages or beneficial effects: since the medicine tablets can be placed in the medicine storage chamber, the medicine tablets have a high antiviral activity rate against the currently popular influenza A H1N1 virus and GX_P2V coronavirus, and the emission flow rate of the volatile components of the medicine can be adjusted according to user needs by adjusting the air permeability of the breathable mesh, thereby adsorbing and filtering harmful substances such as bacteria, viruses, dust, PM2.5 in the air, while being able to actively and effectively inactivate bacteria and viruses by utilizing the volatiles of the medicine tablets in the medicine storage chamber. At the same time, the volatiles of the medicine tablets will enter the respiratory tract and oral cavity with breathing, effectively alleviating the symptoms of nasal congestion caused by rhinitis and colds, so that patients with rhinitis or colds wearing a mask with the medicine storage chamber can not only speed up the recovery of the symptoms, but also greatly reduce the chance of the above viruses being transmitted to others, while healthy users wearing it can greatly improve the virus prevention and control effect; in addition, the volatiles of the medicine tablets can have a refreshing effect, and remove the odor attached to the mask, thereby extending the service life of the mask.

DETAILED DESCRIPTION

[0008] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0009] In the drawings, the shapes and dimensions may be exaggerated for clarity, and the same reference numerals will be used throughout to designate the same or like components.

[0010] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the invention belongs. The words "first", "second" and similar terms used in the patent application specification and claims of the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one", "an" or "the" do not indicate a quantity limitation, but rather indicate the existence of at least one. Words such as "include" or "comprise" mean that the elements or objects appearing before "include" or "comprises" cover the elements or objects listed after "include" or "comprises" and their equivalents, and do not exclude other elements or objects. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0011] In the following description, words such as center, thickness, height, length, front, back, rear, left, right, top, bottom, upper, lower, etc. are defined relative to the structure shown in the drawings. In particular, "height" is equivalent to the dimension from top to bottom, "width" is equivalent to the dimension from left to right, and "depth" is equivalent to the dimension from front to back. They are relative concepts and may therefore change accordingly depending on their different positions and different usage states. Therefore, these or other directions should not be interpreted as restrictive terms.

[0012] Terms referring to attachment, coupling, and the like (eg, "connected" and "attached") refer to structures being fixed or attached to one another, directly or indirectly, through intermediate structures, as well as movable or rigid attachments or relationships, unless expressly stated otherwise.

[0013] Example 1 Figures 1 to 14 Shows embodiment 1 of the present invention, combined with Figures 1 to 4 As shown in FIG. 2 , it can be seen that the drug storage chamber 2 for the mask includes: The receiving seat 21 includes a bottom wall 211 and a side wall 212. The side wall 212 is integrally connected to the bottom wall 211 on its periphery and extends upward from the periphery of the bottom wall 211 to surround and form an opening. The side wall extends above the bottom to form a receiving cavity 216 with an opening 2121. The sealing cover 201 has a shape and size that matches the opening 2121. When the sealing cover 201 is fitted onto the top of the opening 2121, the sealing cover 201 and the opening 2121 form a seal. The bottom wall 211 is provided with a breathable mesh penetrating the upper and lower surfaces thereof, and the breathable mesh is composed of a plurality of breathable holes arranged in a certain pattern; the accommodating cavity 216 is provided with an air baffle 23 rotatably connected to the bottom wall 211, and the air baffle 23 is provided with a diffuser mesh penetrating the upper and lower surfaces thereof, and the diffuser mesh is composed of a plurality of diffuser holes arranged in a certain pattern; the arrangement pattern of the diffuser holes is the same as the arrangement pattern of the breathable holes, so that when the air baffle 23 reciprocates relative to the bottom wall 211, the diffuser mesh can be opened when it is fully open (such as when it is fully open) according to the degree of alignment between the diffuser holes and the breathable holes. Figure 7 ) - Partially open (eg Figures 8 to 10 ) - Completely obscured (e.g. Figure 11 ) three states to switch back and forth, thereby adjusting the air permeability of the breathable mesh; the air baffle 23 is closely attached to the upper surface of the bottom wall 211, and the upper surface of the air baffle 23 is covered with a medicine sheet 24 ( Figures 7 to 11 In the figure, the solid part of the bottom wall 211 is represented by black filling, and the solid part of the air baffle 23 is represented by gray filling). Therefore, the volatilization flow rate of the medicine sheet 24 is different according to the different air permeability of the air mesh. From the perspective of the degree of opening of the air permeable mesh, the more open it is, the greater the volatilization flow rate of the medicine sheet 24.

[0014] In a preferred embodiment, the bottom wall 211 and the air baffle 23 are both disc-shaped, and the air baffle 23 is coaxially rotatably connected to the bottom wall 211 .

[0015] Reference Figure 6 The ventilation holes are arranged to consist of at least three levels of ventilation hole subsets surrounding the center of the bottom wall 211 from the inside to the outside. Each level of ventilation hole subset includes at least one pair of arc-shaped ventilation holes arranged oppositely. The radius and width of the ventilation holes in the same level are equal. Among them, the definition is: The vent subsets starting from the center of the bottom wall 211 and extending outward are the first-level vent subset, the second-level vent subset, the third-level vent subset, ..., the nth-level vent subset. Correspondingly, the inner radius and outer radius of the vents of the first-level vent subset are and The inner radius and outer radius of the second-level vent subset are and The inner radius and outer radius of the third-level vent subset are and ,…, the inner radius and outer radius of the n-th level vent subset are and The width of the vent holes in the first-level vent hole subset is , the width of the vent holes in the second-level vent hole subset is , the width of the vent holes in the third level vent hole subset is ,…, the width of the vent holes of the n-th level vent hole subset is , then: , where ; definition: The nth level vent subset is the high-level vent subset, and the n-1th level vent subset is the low-level vent subset. Then, a vent from the low-level vent subset is arranged between every two vents in the high-level vent subset. Figure 6 In the embodiment shown, the vent subsets are arranged in five levels from the inside to the outside, and each level of the vent subsets includes two vents at the level below. Figure 6 The first air hole subset includes two first air holes 2111 , the second air hole subset includes two second air holes 2112 , the third air hole subset includes two third air holes 2113 , the fourth air hole subset includes two fourth air holes 2114 , and the fifth air hole subset includes two fifth air holes 2115 .

[0016] Since the arrangement rule of the air diffusion holes is the same as that of the air permeable holes, the air diffusion holes are arranged to be composed of at least three levels of air diffusion hole subsets surrounding the center of the air baffle 23 from the inside to the outside. Each level of the air diffusion hole subset includes at least one pair of arc-shaped air diffusion holes arranged oppositely. The radius and width of the air diffusion holes in the same level are equal. Among them, the definition is: The air diffusion hole subsets starting from the center of the air baffle 23 and extending outward are the first-level air diffusion hole subset, the second-level air diffusion hole subset, the third-level air diffusion hole subset, ..., the nth-level air diffusion hole subset. Correspondingly, the inner radius and outer radius of the air diffusion holes of the first-level air diffusion hole subset are respectively and The inner radius and outer radius of the second-level diffuser pore subset are and The inner radius and outer radius of the third-level diffuser pore subset are and ,…, the inner radius and outer radius of the diffusion holes of the nth-level diffusion hole subset are and The width of the first-stage diffuser pore subset is , the width of the second-stage diffuser pore subset is , the width of the third-level diffuser pore subset is ,…, the width of the diffusion holes of the n-th level diffusion hole subset is , then: , where ; definition: The nth level diffuser pore subset is the high-level diffuser pore subset, and the n-1th level diffuser pore subset is the low-level diffuser pore subset. Then, a diffuser pore from the low-level diffuser pore subset is arranged between every two diffusers in the high-level diffuser pore subset. Figure 5 In the embodiment shown, the air diffusion hole subsets are arranged in five levels from the inside to the outside, and each level of the air diffusion hole subsets includes two air diffusion holes at the level below. Figure 5 The first air diffusion hole subset includes two first air diffusion holes 231, the second air diffusion hole subset includes two second air diffusion holes 232, the third air diffusion hole subset includes two third air diffusion holes 233, the fourth air diffusion hole subset includes two fourth air diffusion holes 234, and the fifth air diffusion hole subset includes two fifth air diffusion holes 235. Furthermore, since the outer edge of the fifth air diffusion hole 235 is optional after mating with the accommodating seat 21, to simplify the manufacturing and assembly process, the outer edge of the fifth air diffusion hole 235 has been omitted and is represented by a dotted line to facilitate understanding.

[0017] Reference Figure 3 The accommodating cavity 216 is provided with an even number of limiting lugs 213, and the limiting lugs 213 are arranged to be composed of at least one limiting subset, each limiting subset includes a pair of limiting lugs 213 arranged symmetrically about the center of the bottom wall 211. Figure 3 In the illustrated embodiment, two limiting tabs 213 are provided and are symmetrically arranged about the center of the bottom wall 211 .

[0018] Furthermore, each of the limiting ear pieces 213 is fixed to the inner side of the side wall 212 and extends from the inner side of the side wall 212 toward the center of the bottom wall 211 in parallel with the side wall 212; the height of the limiting ear piece 213 from the bottom wall 211 is not less than the thickness of the air baffle 23, so that a limited gap is formed between the limiting ear piece 213 and the bottom wall 211; each of the limiting ear pieces 213 is aligned with a corresponding air hole of the highest-level air hole subset, and the width of each limiting ear piece 213 is not greater than the width of the air hole corresponding thereto, so that the projection of each limiting ear piece 213 on a corresponding air hole at least partially overlaps with the air hole in the radial direction.

[0019] Furthermore, the arc length of each limiting ear piece 213 is not less than the arc length of the corresponding air hole, so that when the air blocking piece blocks the air hole, the air blocking piece will not fail to seal the air hole due to lack of reaction force at the air hole.

[0020] Reference Figure 1 、 Figure 5 and Figure 7 The cam 232 is secured to the bottom of the base 211 by a spring 236 which engages with the cam 236 when the cam 232 is in engagement with the base 211.

[0021] Reference Figure 3 The outer periphery of the side wall 212 is integrally formed with a skirt 214. The skirt 214 extends radially outward from the outer periphery of the side wall 212. When the sealing cover 201 is fitted onto the top of the opening 2121, the bottom of the sealing cover 201 faces the upper end surface of the skirt 214. As the sealing cover 201 is gradually tightened onto the receiving seat 21, the sealing cover 201 can clamp the mask textile layer between the sealing cover 201 and the skirt 214 until the drug storage chamber 2 is firmly mounted on the mask textile layer.

[0022] Example 1 further discloses a pharmaceutical tablet 24, which is placed in the pharmaceutical storage chamber 2 for the mask as described above, so that its volatile components are emitted outward through the breathable mesh on the bottom wall 211. The pharmaceutical tablet 24 is made of the following raw materials, calculated by mass percentage: Menthol 30wt%; Borneol 15wt%; Camphor 10wt%; Eucalyptus oil 20wt%; Wintergreen oil 10wt%; Turpentine 5wt%; Clove oil 4.4wt%; Orange peel 3.5wt%; Bergamot 2.1wt%.

[0023] Example 1 also provides a new type of mask, referring to Figures 12 to 14The new mask includes a mask body 1, on the left and right sides of which the drug storage chamber 2 and the one-way valve 3 are fixedly installed, wherein the drug storage chamber 2 is provided with a grid hole on the inner side of the mask body 1, and the outer end of the drug storage chamber 2 is opened and the sealing cover 201 is installed by threaded fitting. The left and right wings of the mask body 1 are respectively fixedly connected with a fixing plate 6, and the fixing plate 6 is clamped and connected with an elastic band 4, one of the elastic bands 4 is slidably connected with a hook plate 5, and the inner side of the mask body 1 is covered with an inner support frame 7.

[0024] Furthermore, the hook plate 5 is made of plastic and is provided with a hook opening 501 .

[0025] Furthermore, the fixing plate 6 is made of plastic and includes a connecting portion 601, which is connected to the mask body 1 by hot melt welding. Clamping slits 602 are respectively provided on both sides of the connecting portion 601, and the two clamping slits 602 are interference fit to fix and clamp the two ends of the elastic band 4.

[0026] Furthermore, the inner support frame 7 is a mask-shaped hollow frame made of plastic.

[0027] Principle of Use: By opening the sealing cover 201, the medication tablet 24 can be placed into the medication storage chamber 2 and then tightening the sealing cover 201. When the mask is worn, the medication will emit an odor, thereby improving the odor environment inside the mask, making the mouth and nose more comfortable and helping to prevent and treat oral and nasal diseases. If the elastic band 4 is not the right length when wearing the mask, it can be adjusted by pulling the elastic band 4 appropriately to move it within the clamping gap 602. If the elastic band 4 breaks, it can be directly removed and replaced. When wearing, another elastic band 4 is hooked into the hook opening 501 through the hook plate 5. The two elastic bands 4 are connected and tightened around the head, thereby securing the mask body 1 to the mouth and nose. The inner support frame 7 supports the mask body 1 to prevent it from deforming and sticking to the face. The installed one-way valve 3 makes breathing easier and improves wearer comfort.

[0028] Example 2 The difference between Example 2 and Example 1 is that: The pharmaceutical tablet 24 is made of the following raw materials in terms of mass percentage: Menthol 40wt%; Borneol 5wt%; Camphor 8wt%; Eucalyptus oil 30wt%; Wintergreen oil 2wt%; Turpentine 10wt%; Clove oil 3.5wt%; Orange peel 1wt%; Bergamot 0.5wt%.

[0029] The difference between the disclosed new mask in Example 2 and that disclosed in Example 1 is that the drug storage chamber 2 is detachably mounted on the mask body 1; when the drug storage chamber 2 is mounted on the mask body 1, the breathable mesh is exposed toward the inner side of the mask body 1, and the sealing cover 201 is exposed toward the outer side of the mask body 1; wherein, the mask body 1 is foldable, cup-shaped or flat-plate type.

[0030] Furthermore, the left and right wings of the mask body 1 are respectively fixedly connected with fixing plates 6, and the fixing plates 6 are clamped and connected with elastic bands 4, and one of the elastic bands 4 is slidably connected with a hook plate 5 by a buckle.

[0031] Furthermore, the hook plate 5 is made of plastic and is provided with a hook opening 501 .

[0032] Furthermore, the fixing plate 6 is made of plastic and includes a connecting portion 601, which is connected to the mask body 1 by hot melt welding. Clamping slits 602 are respectively provided on both sides of the connecting portion 601, and the two clamping slits 602 are interference fit to fix and clamp the two ends of the elastic band 4.

[0033] Example 3 The difference between Example 3 and Example 1 is that: The pharmaceutical tablet 24 is made of the following raw materials in terms of mass percentage: Menthol 5wt%; Borneol 25wt%; Camphor 15wt%; Eucalyptus oil 40wt%; Wintergreen oil 6wt%; Turpentine 5wt%; Clove oil 1wt%; Orange peel 2wt%; Bergamot 1wt%.

[0034] Example 4 The difference between Example 4 and Example 1 is that: The toggle adjustment rod 236 is fitted into one of the air holes in the highest level air hole subset and exposed from the bottom of the bottom wall 211. The air hole fitted with the toggle adjustment rod 236 is defined as a guide hole. Figure 6 and Figure 7 In the embodiment shown, it can be seen that when the adjusting rod 236 is engaged with one of the fifth vent holes 2115, the fifth vent hole 2115 becomes a guide hole. Figure 6Two locking holes 2116 are formed at the circumferential end of the guide hole. The guide hole communicates with the locking holes 2116. The diameter of the locking holes 2116 is no larger than the diameter of the toggle adjustment rod 236. A guide section 2117 is formed between each locking hole 2116 and the guide hole. The guide section 2117 extends from the inner side of the guide hole and gradually rises toward the inner side of the guide hole, causing the diameter of the guide hole to gradually decrease from the raised section to the locking hole 2116. Therefore, when the toggle adjustment rod 236 rotates to one of the locking holes 2116, the rotation of the toggle adjustment rod 236 and the air baffle 23 is restricted by the locking holes 2116, preventing the air permeability of the air mesh from being uncertain due to the unstable position of the air baffle 23.
