Description

Technical Field

[0001] The utility model relates to the technical field of protective masks, and more specifically, to a moxibustion smoke-proof mask. Background Art

[0002] During moxibustion, a large amount of smoke is produced, which not only affects the surrounding environment but also poses a potential threat to the health of the practitioners. To address this issue, moxibustion smoke masks have emerged. However, traditional moxibustion smoke masks have many shortcomings in design and use.

[0003] Chinese patent publication number CN220877552U discloses a smoke mask comprising a mask body and a respiratory filter assembly. The respiratory filter assembly comprises a first filter layer and an activated carbon bag, the activated carbon bag being positioned between the porous sealing cover and the first filter layer, and a second filter layer being disposed within the externally threaded tube. The activated carbon bag, the first filter layer, and the second filter layer cooperate to purify the air. The externally threaded tube can be removed by fitting the internally threaded ring and the externally threaded tube, facilitating removal and replacement of the second filter layer. The porous sealing cover and the externally threaded tube then cooperate to facilitate removal and replacement of the activated carbon bag.

[0004] However, the activated carbon bag, the first filter layer and the second filter layer of the smoke mask are all directly arranged in the external threaded tube, and the movement of the second filter layer is restricted by setting a limit ring and a fixing ring. When removing the second filter layer, the fixing ring needs to be removed first. Since the first filter layer and the activated carbon bag are directly connected to the external threaded tube, it takes a lot of work to replace the first filter layer and the activated carbon bag, and there is still a problem of poor disassembly and assembly convenience. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a moxibustion smoke-proof mask in view of the above-mentioned defects of the prior art.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A moxibustion smoke-proof mask is constructed, comprising a mask body and a respiratory filter assembly arranged on the mask body, wherein the respiratory filter assembly comprises a filter tube detachably connected to the mask body and a plurality of mounting rings built into the filter tube, wherein the plurality of mounting rings are fitted together to form a flow channel, and an activated carbon filter bag, a first filter layer, and a second filter layer are respectively arranged in the plurality of mounting rings, which are located in the flow channel, and a cover plate is provided at the outer end of the filter tube, wherein the cover plate has a plurality of through holes communicating with the flow channel.

[0008] As an improvement of the moxibustion smoke mask, both ends of the filter tube respectively have a first threaded portion for cooperating with the mask body and a second threaded portion for cooperating with the cover plate.

[0009] As an improvement of the moxibustion smoke mask, a flexible layer is provided on the outer surface of the first threaded portion. After the first threaded portion is connected to the mask body, the flexible layer is in an extruded state.

[0010] As an improvement to the moxibustion smoke mask, an annular protrusion is provided on the inner side of the cover plate. When the cover plate is connected with the second threaded portion, the annular protrusion squeezes the mounting ring.

[0011] As an improvement to the moxibustion smoke mask, both side end faces of the mounting ring are provided with a sealing rubber layer.

[0012] As an improvement of the moxibustion smoke mask, a limiting strip is provided on the inner wall of the filter tube along the axial direction, and the outer wall of the mounting ring has a groove that cooperates with the limiting strip.

[0013] As an improvement of the moxibustion smoke-proof mask, the mask body is provided with an observation mirror, and the observation mirror has an anti-fog function.

[0014] As an improvement of the moxibustion smoke-proof mask, the mask body is provided with a flexible baffle, which is used to contact and fit with the face and nose bridge of a person.

[0015] As an improvement of the moxibustion smoke mask, the surface of the observation mirror is provided with an anti-fog coating.

[0016] As an improvement of the moxibustion smoke-proof mask, a glasses frame is detachably provided in the mask body, and the glasses frame is provided with lenses for aligning and matching with the human eye area.

[0017] The beneficial effect of the present invention is that the activated carbon filter bag, the first filter layer, and the second filter layer are respectively arranged in three mounting rings, forming three independent parts. During installation, the three mounting rings need only be placed in the filter tube in sequence to complete the installation of the activated carbon filter bag, the first filter layer, and the second filter layer. When disassembly is required after long-term use, the filter tube can be removed from the mask body or the cover plate so that one end of the filter tube is open. The filter tube can then be tilted to remove the three mounting rings and replaced. Furthermore, when replacing, only the three mounting rings containing the activated carbon filter bag, the first filter layer, and the second filter layer need to be placed in the filter tube. While ensuring a good filtering effect, the steps for disassembling and assembling the activated carbon filter bag, the first filter layer, and the second filter layer are reduced, saving disassembly and assembly time and improving the ease of replacement.

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 4As shown, a moxibustion smoke-proof mask includes a mask body 1 and a respiratory filter assembly 2 arranged on the mask body 1. The respiratory filter assembly 2 includes a filter tube 21 detachably connected to the mask body 1 and a plurality of mounting rings 22 built into the filter tube 21. The plurality of mounting rings 22 are fitted together to form a flow channel 221, and an activated carbon filter bag 23, a first filter layer 24 and a second filter layer 25 are respectively arranged in the plurality of mounting rings 22, which are located in the flow channel 221. A cover plate 26 is provided at the outer end of the filter tube 21, and the cover plate 26 has a plurality of through holes 261 connected to the flow channel 221.

[0029] Specifically, the activated carbon filter bag 23 mainly absorbs harmful gases and odors from the smoke, while the first filter layer 24 and the second filter layer 25 further filter particulate matter and impurities in the air to ensure that the air breathed is cleaner. When the user breathes, the air enters the flow channel 221 through the through hole 261. After being filtered by the activated carbon filter bag 23, the first filter layer 24, and the second filter layer 25, the smoke and harmful gases generated during the moxibustion process are effectively filtered, and clean air is inhaled by the user. There are three mounting rings 22, and the activated carbon filter bag 23, the first filter layer 24, and the second filter layer 25 are respectively placed in the three mounting rings 22 to form three independent parts. During installation, simply place the three mounting rings 22 sequentially into the filter tube 21 to complete the installation of the activated carbon filter bag 23, the first filter layer 24, and the second filter layer 25. To disassemble the filter after extended use, simply remove the filter tube 21 from the mask body 1 or remove the cover plate 26 so that one end of the filter tube 21 is open. Then, tilt the filter tube 21 to remove the three mounting rings 22 for replacement. To replace the filter, simply place the three mounting rings 22 containing the activated carbon filter bag 23, the first filter layer 24, and the second filter layer 25 into the filter tube 21. This ensures a good filtration effect while reducing the number of steps required to disassemble and assemble the activated carbon filter bag 23, the first filter layer 24, and the second filter layer 25, saving time and simplifying replacement.

[0030] Elastic bands are provided on both sides of the mask body, which are connected and tied together by the elastic bands on both sides and fixed to the user's head. The outer ends of the elastic bands on both sides can be connected by Velcro.

[0031] Furthermore, the first filter layer 24 is mainly responsible for preliminary filtration. It uses materials that can effectively block large particles, such as polyester fibers or non-woven fabrics, to remove large particles and dust in the air; the second filter layer 25 is located after the first filter layer 24 and uses a finer filter material, which may be a HEPA filter (high-efficiency particulate filter), for further filtering tiny particles, bacteria and viruses, thereby improving the cleanliness of the air.

[0032] In other embodiments, the mounting ring 22 provided with the activated carbon filter bag 23, the mounting ring 22 provided with the first filter layer 24, and the mounting ring 22 provided with the second filter layer 25 can all be set as disposable items, which can be directly taken out and replaced after use, making the replacement of the activated carbon filter bag 23, the first filter layer 24, and the second filter layer 25 and the cleaning of the filter tube 21 easier.

[0033] In some embodiments of the present application, the filter tube 21 has a first threaded portion 211 at each end for mating with the mask body 1 and a second threaded portion 212 for mating with the cover plate 26. Specifically, the first threaded portion 211 is located at one end of the filter tube 21 and is used to threadably connect with a corresponding portion of the mask body 1, thereby achieving a detachable connection between the filter tube 21 and the mask body 1. This threaded connection allows the user to easily remove the filter tube 21 from the mask body 1 for cleaning or replacement. The second threaded portion 212 is located at the other end of the filter tube 21 and is used to threadably connect with a corresponding portion of the cover plate 26, thereby achieving a detachable connection between the cover plate 26 and the filter tube 21. The user can access the interior of the filter tube 21 by removing the cover plate 26, thereby easily replacing the activated carbon filter bag 23, the first filter layer 24, and the second filter layer 25.

[0034] In some embodiments of the present application, a flexible layer 213 is provided on the outer surface of the first threaded portion 211. After the first threaded portion 211 is mated and connected to the mask body 1, the flexible layer 213 is in an extruded state. Specifically, when the first threaded portion 211 is mated and threadedly connected to the mask body 1, the flexible layer 213 is extruded and deformed upon contact with the mask body 1, thereby closely fitting the connection surface of the mask body 1. The flexible layer 213 has a certain degree of elasticity and resilience, and can fill the gap between the mask body 1 and the filter tube 21, reducing air leakage caused by the gap and maintaining a good filtering effect of the respiratory filter assembly 2. The material of the flexible layer 213 can be set to silicone, rubber, or soft plastic.

[0035] In some embodiments of the present application, the inner side of the cover plate 26 has an annular protrusion 262. When the cover plate 26 is mated with the second threaded portion 212, the annular protrusion 262 squeezes the mounting ring 22. Specifically, when the cover plate 26 is mated with the second threaded portion 212 of the filter tube 21, the annular protrusion 262 squeezes the mounting ring 22, causing the three mounting rings 22 to fit tightly within the filter tube 21 and be fixed in position, thereby preventing the mounting rings 22 from shaking during use; preventing unfiltered air from entering through the gaps between the mounting rings 22, ensuring the sealing between the mounting rings 22 and the filter tube 21 and the flow channel 221, so that air can be filtered through the flow channel 221 and accurately input into the mask body 1.

[0036] In some embodiments of the present application, both end surfaces of the mounting rings 22 are provided with a sealant layer. Specifically, the sealant layer utilizes its elasticity to form a tight seal between adjacent mounting rings 22. This not only fills the tiny gaps between the mounting rings 22, further preventing unfiltered air from entering through these gaps, but also reduces air leakage, ensuring that all air entering the flow channel 221 undergoes multiple layers of filtration. The sealant layer on both end surfaces of the mounting rings 22 enhances the seal between the mounting rings 22 and reduces leakage.

[0037] In some embodiments of the present application, a limit strip 214 is provided axially on the inner wall of the filter tube 21, and a groove 222 is provided on the outer wall of the mounting ring 22 to cooperate with the limit strip 214. Specifically, the limit strip 214 on the inner wall of the filter tube 21 serves as a guide and fixation mechanism, while the groove 222 on the outer wall of the mounting ring 22 closely cooperates with the limit strip 214. By inserting the limit strip 214 into the groove 222 on the outer wall of the mounting ring 22, the position of the mounting ring 22 within the filter tube 21 is ensured to be stable, allowing the mounting ring 22 to be precisely positioned and fixed within the filter tube 21, preventing displacement or rotation.

[0038] In some embodiments of the present application, the mask body 1 includes an observation mirror 3, which has an anti-fog function. Specifically, as part of the mask body 1, the observation mirror 3 ensures that the user can clearly see the external environment while isolating smoke and harmful gases from the outside of the mask, thereby protecting the user's eyes and respiratory tract. The anti-fog function of the observation mirror 3 prevents the user from experiencing discomfort due to fogging or the need for frequent wiping during prolonged use of the mask, thereby improving user comfort.

[0039] In some embodiments of the present application, the mask body 1 is provided with a flexible stopper 11, which is used to contact and fit with the face and bridge of the nose of a person. Specifically, the flexible stopper 11 is made of a soft, flexible material so that it can closely fit the facial contours of different users, especially areas such as the bridge of the nose and the wings of the nose, effectively reducing the gap between the mask and the face. The close fit of the flexible stopper 11 to the face reduces or eliminates air leakage from the edge of the mask, thereby enhancing the sealing of the entire mask. This sealing is crucial for preventing smoke and harmful gases generated by moxibustion from entering the interior of the mask. In addition, when breathing, the exhaled water vapor and hot air are not easily leaked from the edge of the mask through the setting of the flexible stopper 11, reducing the amount of water vapor directly impacting the observation mirror 3, thereby achieving an anti-fog function. The material of the flexible stopper 11 can be set to silicone, sponge, memory foam, TPE (thermoplastic elastomer) or soft rubber.

[0040] In some embodiments of the present application, Figure 5 、 Figure 6 and Figure 7As shown, the mask body 1 also includes a heat dissipation assembly, which includes an intake fan 5 and an exhaust fan 6. A plurality of intake holes 7 and a plurality of exhaust holes 8 are provided in the mask body 1. The plurality of intake holes 7 are respectively distributed on both sides of the flexible baffle 11, and the plurality of exhaust holes 8 are also respectively distributed on both sides of the flexible baffle 11. The mask body 1 has an intake flow channel connecting the intake fan 5 with the intake holes 7, and an exhaust flow channel connecting the exhaust fan 6 with the exhaust holes 8. Specifically, there are two air inlet holes 7 and two exhaust holes 8. The two air inlet holes 7 are located on the upper and lower sides of the mask body 1, respectively, for delivering air to the eye area and the mouth and nose area. A filter component that can filter and purify air is removably installed inside the air inlet fan 5. The two exhaust holes 8 are located on the upper and lower sides of the mask body 1, respectively, for exhausting air from the eye area and the mouth and nose area. The cooperation between the air inlet fan 5 and the exhaust fan 6 can accelerate the air flow in the eye area and the mouth and nose area, reduce the user's sweating rate, and prevent sweat from flowing into the observation mirror 3 or the user's personal myopia glasses, causing fogging and making it difficult to observe. In addition, when the flexible barrier 11 is in contact with the user's face, it can separate the eye area and the mouth and nose area inside the mask body 1, preventing hot air from exhaled from flowing into the eye area, further preventing the problem of fogging, and facilitating long-term wear.

[0041] In some embodiments of the present application, an anti-fog coating is provided on the surface of the observation mirror 3. Specifically, the anti-fog coating is hydrophilic and has a certain microporous structure. It can absorb moisture in the air to form a very thin water film instead of forming water droplets. The anti-fog coating provided on the surface of the observation mirror 3 can effectively absorb and disperse water vapor through its special hydrophilicity and microporous structure, thereby reducing the formation of water droplets on the mirror surface. The observation mirror 3 can remain clear even in an environment with a large temperature difference or high humidity. Its effects include improving the clarity of the field of view, ensuring that the user can clearly observe the condition of the moxibustion skin during the moxibustion process; extending the clear field of view time of the observation mirror 3, improving the user experience; at the same time, it can also reduce the wear caused by frequent wiping and reduce maintenance costs.

[0042] In some embodiments of the present application, a glasses frame 4 is detachably provided in the mask body 1, and the glasses frame 4 is provided with a lens 401 for aligning and cooperating with the eye area of ​​a person. Specifically, the glasses frame 4 is provided to be detachable, and the user can choose whether to install the glasses frame 4 as needed; if necessary, it can be easily installed in the mask body 1; if not needed, it can be conveniently removed. The glasses frame 4 ensures that the lens 401 can be aligned and cooperating with the eye area of ​​a person, and the user maintains a clear line of sight when using the mask without worrying about obstructed vision or discomfort. The lens 401 provided on the glasses frame 4 can be an ordinary myopia lens 401, or it can be a lens 401 with specific functions, such as anti-fog, anti-scratch, anti-ultraviolet, etc. These lenses 401 can provide additional protection or convenience to meet the needs of different users.
