Description

Technical Field

[0001] The invention relates to the field of oxygen mask cleaning, in particular to a cleaning and drying device for aviation oxygen supply masks. Background Art

[0002] The oxygen mask used by pilots is an important piece of equipment. Its main function is to provide pilots with enough oxygen to ensure their safety when flying at high altitudes. In order to increase friction and improve air tightness, a layer of suede is glued to some oxygen masks. This design can effectively prevent oxygen leakage and ensure smooth breathing for pilots.

[0003] However, since pilots need to wear this oxygen mask for a long time, the sweat and oil stains on their faces will penetrate into the suede. If the mask is not cleaned in time for a long time, the suede of the mask will become sticky and yellow, and produce odor, which will not only affect the wearing comfort, but also may affect the health and safety of the pilots.

[0004] In addition, the suede and the mask body are connected together by gluing, which makes it very difficult to clean and maintain the mask. Users can only clean it with a manual brush, which is time-consuming and labor-intensive, and it is difficult to achieve the desired cleaning effect. If you choose to return the mask to the factory to replace the suede, the cycle will be relatively long, which will undoubtedly affect the normal use of the pilot. In view of this, we propose a cleaning and drying device for aviation oxygen supply masks. Summary of the invention

[0005] The object of the present invention is to provide a cleaning and drying device for aviation oxygen supply masks to solve the problems raised in the above background technology.

[0006] To achieve the above object, the present invention provides a cleaning and drying device for an aviation oxygen supply mask, comprising a shell, a water storage component is arranged inside the shell, an outer auxiliary component is arranged inside the water storage component, an inner auxiliary component is arranged inside the outer auxiliary component, and a disturbance component is arranged inside the inner auxiliary component, wherein:

[0007] When washing the mask, the water storage component is used to store water so that the water flows through the outer auxiliary component and mixes with the mask on the surface of the inner auxiliary component. The inner auxiliary component is used to rotate the mask inside the cavity formed by the sandwich of the outer auxiliary component and the inner auxiliary component, and the mask is rubbed against the inner side of the outer auxiliary component. When the inner auxiliary component drives the mask to rotate, it also drives the disturbance component to disturb and roll the mask, so that different parts of the mask rub against the outer auxiliary component.

[0008] During drying, the water storage component discharges the stored water flow, so that the mask and the water flow are separated between the outer auxiliary component and the inner auxiliary component, and the inner auxiliary component starts to rotate in the opposite direction to drive the mask to tumble in the interlayer cavity between the outer auxiliary component and the inner auxiliary component. At the same time, the disturbance component driven by the reverse rotation of the inner auxiliary component will squeeze the mask, forcing the mask to fit the outer auxiliary component, and the moisture contained in the mask is discharged through the squeezing effect. At the same time, the inner auxiliary component starts to heat up and dries the mask by blowing hot air.

[0009] As a further improvement of the present technical solution, the water storage assembly includes a water tank, the outer wall of the water tank is fixedly connected to the inner wall of the outer shell, and the side wall of the water tank is installed with a water inlet pipe. The water inlet pipe is used to introduce water into the water tank during the mask cleaning operation to clean the mask. A water outlet pipe is installed at the bottom of the water tank. The water outlet pipe is opened during the drying process to discharge the water in the water tank, thereby separating the mask from the water.

[0010] As a further improvement of the present technical solution, the external auxiliary component includes an outer frame, and the outer frame is enclosed to form a hexagon, the side walls of the outer frame are rotatably connected to the inner wall of the sink, the inner wall of the outer frame is fixedly connected to a plurality of plug rods, and the plurality of plug rods are spliced ​​horizontally and vertically to form a "well" shaped panel, and buckles are fixedly connected on both sides of the top of the outer frame, and the buckles are used to clamp the "well" shaped panel on the upper end of the outer frame.

[0011] As a further improvement of the technical solution, the inner auxiliary component includes a heating cylinder, and both side walls of the heating cylinder are fixedly connected to first rotating rods, and one end of the two first rotating rods away from the heating cylinder is fixedly connected to the inner wall of the outer frame.

[0012] As a further improvement of the present technical solution, the disturbance assembly includes a second rotating rod, which is rotatably connected to the inner wall of the heating tube, and the outer wall of the second rotating rod is fixedly connected to a column gear, and the column gear is meshed with a tooth plate, the upper side of the tooth plate is fixedly connected to the disturbance rod, and the lower end of the disturbance rod is rotatably connected to the outer wall of the second rotating rod, and the upper end of the disturbance rod passes through the inner wall of the heating tube and is fixedly connected to an inclined plate.

[0013] As a further improvement of the technical solution, when the inclined plate is cleaning the mask, the heating cylinder rotates forwardly to drive the inclined plate to rotate inside its outer frame. At this time, the front of the inclined plate impacts the mask, causing a disturbance to the mask and interweaving the masks stacked together, thereby reducing the continued accumulation of masks and causing the masks to roll over.

[0014] As a further improvement of the technical solution, when the inclined plate is drying, the heating cylinder rotates in the opposite direction to drive the inclined plate to rotate inside its outer frame. At this time, the back side of the inclined plate squeezes the mask, exerts an extrusion effect on the mask, squeezes the mask against the inner wall of the outer frame, and discharges moisture from the mask.

[0015] As a further improvement of the present technical solution, a driving machine is installed on the lower side of the inner part of the outer shell, the output end of the driving machine is rotatably connected to a belt, the output end of the driving machine is connected to a driving rod through a belt transmission, the end of the driving rod away from the belt is transmission-connected to a rotating shaft, and the end of the rotating shaft away from the driving rod is fixedly connected to the outer wall of the outer frame.

[0016] As a further improvement of the technical solution, a dust cover is rotatably connected to the upper side of the shell, and an observation window is provided inside the dust cover for observing the working status during cleaning and drying.

[0017] As a further improvement of the technical solution, one end of the second rotating rod is rotatably connected to the first rotating rod and the inner wall of the rotating shaft, and a groove is provided at one end close to the rotating shaft, an opening is provided on the outer wall of the rotating shaft and an elastic block is clamped inside, a pull rod is abutted on the upper end of the elastic block, and the lower end of the pull rod abuts on the upper end of the elastic block, wherein:

[0018] The pulling rod is moved downward to squeeze the elastic block and insert the elastic block into the slot at one end of the second rotating rod, so that the rotation of the rotating shaft drives the second rotating rod to rotate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the cleaning and drying device for the aviation oxygen mask, a water storage component is provided to store water flow, so that the water flow can pass through the outer auxiliary component and mix with the mask on the surface of the inner auxiliary component. The main function of the inner auxiliary component is to ensure that the mask rotates in the cavity formed by the outer auxiliary component and the inner auxiliary component. In this process, the mask will fit tightly on the inner side of the outer auxiliary component, thereby generating friction. At the same time, as the inner auxiliary component drives the mask to rotate, the disturbance component will also work synchronously to disturb and roll the mask, so that different parts of the mask can generate friction with the outer auxiliary component, thereby improving the mixing effect. By continuously rolling and rubbing the mask, a strong vortex effect is generated by rotation. This physical action simulates the traditional hand washing and rubbing action, effectively loosens and removes dirt on the mask, replaces the traditional manual brush, saves cleaning time and improves cleaning efficiency.

[0021] 2. In the cleaning and drying device for the aviation oxygen mask, a water storage component is provided to discharge the accumulated water flow. This is to achieve effective separation of the mask and the water flow between the outer auxiliary component and the inner auxiliary component. Subsequently, the inner auxiliary component begins to rotate in the opposite direction, driving the mask to tumble in the interlayer cavity between the outer auxiliary component and the inner auxiliary component. At the same time, the disturbance component driven by the reversal of the inner auxiliary component will exert an extrusion effect on the mask to ensure that the mask fits tightly to the outer auxiliary component. Through this extrusion effect, the moisture contained in the mask can be effectively discharged. In addition, the inner auxiliary component simultaneously starts the heating function and uses the hot air blown out to dry the mask. After completing the cleaning process, the drying process is quickly carried out, which greatly shortens the time required for drying, improves the drying efficiency, and thus realizes the rapid reuse of the mask. This approach effectively solves the problem of inconvenience in cleaning and maintaining the mask, and significantly improves the timeliness and convenience of its use.

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 9 As shown, this embodiment provides a cleaning and drying device for an aviation oxygen supply mask, comprising a housing 101, a water storage component 200 is provided inside the housing 101, an outer auxiliary component 400 is provided inside the water storage component 200, an inner auxiliary component 300 is provided inside the outer auxiliary component 400, and a disturbance component 310 is provided inside the inner auxiliary component 300, wherein:

[0039] When washing the mask, the water storage component 200 is used to store water so that the water flows through the outer auxiliary component 400 and mixes with the mask on the surface of the inner auxiliary component 300. The inner auxiliary component 300 is used to rotate the mask inside the cavity formed by the sandwich between the outer auxiliary component 400 and the inner auxiliary component 300, and the mask is rubbed against the inner side of the outer auxiliary component 400. When the inner auxiliary component 300 drives the mask to rotate, it also drives the disturbance component 310 to disturb and roll the mask, so that different parts of the mask rub against the outer auxiliary component 400.

[0040] During drying, the water storage component 200 discharges the stored water flow, so that the mask between the outer auxiliary component 400 and the inner auxiliary component 300 is separated from the water flow, and the inner auxiliary component 300 starts to rotate in the opposite direction to drive the mask to tumble in the interlayer cavity between the outer auxiliary component 400 and the inner auxiliary component 300. At the same time, the disturbance component 310 driven by the reverse rotation of the inner auxiliary component 300 will squeeze the mask, forcing the mask to fit the outer auxiliary component 400, and the moisture contained in the mask is discharged through the squeezing effect. At the same time, the inner auxiliary component 300 starts to heat up and dries the mask by blowing hot air.

[0041] The present invention fully considers that when the pilot wears the oxygen mask for a long time, the sweat and oil stains on the face are easy to penetrate into the suede material. If the cleaning work is neglected for a long time, the suede will gradually become sticky, yellow, and emit odor, which not only significantly reduces the comfort of wearing, but also may pose a potential threat to the health and safety of the pilot. At the same time, since the suede is connected to the mask body by gluing, the cleaning and maintenance of the mask becomes extremely difficult. The traditional cleaning method mainly relies on a manual brush, which is not only time-consuming and labor-intensive, but also difficult to achieve the ideal cleaning effect. If the mask is returned to the factory to replace the suede part, it will face a long replacement cycle, which will undoubtedly cause inconvenience to the normal use of the pilot. Therefore, by setting a water storage component 200 to store water flow, the water flow can pass through the outer auxiliary component 400 and mix with the mask on the surface of the inner auxiliary component 300. The main function of the inner auxiliary component 300 is to ensure that the mask rotates in the cavity formed by the outer auxiliary component 400 and the inner auxiliary component 300. During this process, the mask will fit tightly against the inner side of the outer auxiliary component 400, thereby generating friction. At the same time, as the inner auxiliary component 300 drives the mask to rotate, the disturbance component 310 will also work synchronously to disturb and roll the mask, so that different parts of the mask can generate friction with the outer auxiliary component 400, thereby improving the mixing effect. By continuously rolling and rubbing the mask, and generating a strong vortex effect through rotation. This physical action simulates the traditional hand-washing rubbing action, effectively loosens and removes dirt on the mask, replaces the traditional manual brush, saves cleaning time and improves cleaning efficiency;

[0042] At the same time, since the cleaned mask needs to be dried after cleaning to ensure that the pilot can put it into use quickly, a water storage component 200 is set to discharge the accumulated water flow during the drying process. This is to achieve effective separation of the mask and the water flow between the outer auxiliary component 400 and the inner auxiliary component 300. Subsequently, the inner auxiliary component 300 starts to rotate in the opposite direction, driving the mask to tumble in the interlayer cavity between the outer auxiliary component 400 and the inner auxiliary component 300. At the same time, the disturbance component 310 driven by the reverse rotation of the inner auxiliary component 300 will exert an extrusion effect on the mask to ensure that the mask fits tightly to the outer auxiliary component 400. Through this extrusion effect, the moisture contained in the mask can be effectively discharged. In addition, the inner auxiliary component 300 simultaneously starts the heating function and uses the hot air blown out to dry the mask. The drying process is quickly carried out after the cleaning process is completed, which greatly shortens the time required for drying, improves the drying efficiency, and thus realizes the rapid reuse of the mask. This approach effectively solves the problem of inconvenience in cleaning and maintaining the mask, and significantly improves the timeliness and convenience of its use.

[0043] Among them, the aviation oxygen mask in the prior art is provided with a communication device for communicating between the air and the ground. However, considering that the communication device is easily damaged when the aviation oxygen mask is cleaned and immersed in liquid for a long time, conventional means can be used (for example, before immersion, the electronic components in the mask are wrapped or sealed with professional waterproof sealing materials. These materials can be waterproof tapes, waterproof films or other polymer composite materials to ensure that water cannot penetrate into the electronic components, or a waterproof coating such as silica gel, epoxy resin, etc. is coated on the surface of the electronic components to form a protective layer to prevent water molecules from invading. This coating can be removed by chemical or physical means after cleaning without affecting the function of the electronic components) for waterproof protection. This is common knowledge of personnel in this technical field and will not be elaborated here.

[0044] On the basis of the above, the specific structure needs to be disclosed in detail:

[0045] First, the water storage component 200 is implemented to store water flow, so that the water flow can pass through the outer auxiliary component 400 and mix with the mask on the surface of the inner auxiliary component 300, such as Figure 3 As shown, the water storage component 200 includes a water tank 201, the outer wall of the water tank 201 is fixedly connected to the inner wall of the housing 101, and a water inlet pipe 202 is installed on the side wall of the water tank 201. The water inlet pipe 202 is used to introduce water flow into the water tank 201 during the mask cleaning operation to clean the mask. A water outlet pipe 203 is installed at the bottom of the water tank 201. The water outlet pipe 203 is opened during the drying process to discharge the water flow in the water tank 201, so that the mask is separated from the water flow, wherein:

[0046] The function of the water inlet pipe 202 is to accurately guide the water flow to the inside of the water tank 201, while the water tank 201 has the important function of storing the water flow introduced by the water inlet pipe 202 to ensure that the water flow inside the water tank 201 reaches a certain depth. On this basis, the outer auxiliary component 400 and the inner auxiliary component 300 can be completely immersed in the water inside the water tank 201 to meet the conditions required for their work. This design enables the immersion process to effectively soften and dissolve the stains and grease attached to the surface of the mask, thereby making these difficult-to-remove impurities easier to be washed away by the water flow. In addition, by combining the use of warm water and neutral detergent, it can fully penetrate deep into the mask fiber, thereby achieving a comprehensive cleaning of the inner and outer layers of the mask and achieving the ideal effect of deep cleaning. The function of the water outlet pipe 203 is to be responsible for opening after the cleaning process is completed to achieve the discharge of wastewater. Given that its installation position is located on the lower side of the water tank 201, the design makes full use of the effects of gravity and water pressure difference to ensure the effective discharge of wastewater. This not only separates the mask from the water flow, but also provides convenient conditions for the subsequent drying process, thereby improving the overall work efficiency and operational convenience;

[0047] Specifically, the staff first properly places the mask in the interlayer cavity between the outer auxiliary component 400 and the inner auxiliary component 300. Then, the water inlet pipe 202 is started, and the water inlet pipe 202 immediately injects water into the water tank 201 to start the cleaning operation. After the cleaning operation is completed, the water outlet pipe 203 is immediately started to completely discharge the water in the water tank 201. After the water flow is discharged, the drying operation is immediately started, thereby improving the overall work efficiency and operation convenience.

[0048] Secondly, the mask is rotated in the cavity formed by the sandwich of the outer auxiliary component 400 and the inner auxiliary component 300, and the mask is rubbed against the inner side of the outer auxiliary component 400, such as Figure 4 and Figure 5 As shown, the outer auxiliary component 400 includes an outer frame 401, and the outer frame 401 is enclosed to form a hexagon. The side wall of the outer frame 401 is rotatably connected to the inner wall of the water tank 201. The inner wall of the outer frame 401 is fixedly connected with a plurality of plug rods 402. The plurality of plug rods 402 are spliced ​​horizontally and vertically to form a "well" shaped panel. The top two sides of the outer frame 401 are fixedly connected with buckles 403, and the buckles 403 are used to clamp the "well" shaped panel at the upper end of the outer frame 401. A driving machine 406 is installed on the lower side of the inner part of the housing 101, and the output end of the driving machine 406 is rotated. The inner auxiliary component 300 includes a heating cylinder 301, and both side walls of the heating cylinder 301 are fixedly connected to first rotating rods 302, and both ends of the two first rotating rods 302 are fixedly connected to the inner wall of the outer frame 401, wherein:

[0049] During cleaning:

[0050] The outer frame 401 is used to support the insertion rod 402 for orderly horizontal and vertical overlap, thereby forming a "well"-shaped panel, so that the mask can rub against its inner wall, and the friction area is increased through the "well" shape. By increasing the friction area, the same force can act over a larger range, thereby removing stains and dirt more evenly and effectively, and is more conducive to the water flow inside the water tank 201 to freely enter the outer frame 401, thereby better mixing with the mask. The buckle 403 is designed to open the well-shaped panel at the upper end of the outer frame 401, so that the staff can easily place the mask into the outer frame 401. Subsequently, by firmly locking the buckle 403, it is possible to ensure that the connection between the tic-tac-toe panel and the outer frame 401 is more stable and reliable during the rotation of the outer frame 401, thereby improving the stability of the overall structure. The driver 406, as the core power source of the entire set of equipment, is responsible for providing stable and continuous power output to ensure the normal and efficient operation of the entire device. The belt 407, as a key transmission component, is responsible for accurately transmitting the power output by the driver 406 to the drive rod 404, thereby realizing the rotation of the drive rod 404, and the drive rod 404 is equipped with a meshing gear set at one end opposite to the rotating shaft 405, which is mainly used for power transmission. Under the push of the drive rod 404, the rotating shaft 405 rotates accordingly through the meshing transmission connection mechanism.

[0051] Since the rotating shaft 405 is fixedly connected to the outer wall of the outer frame 401, the rotation of the rotating shaft 405 will directly cause the outer frame 401 to rotate. The centrifugal force generated by this rotation process makes the mask fit tightly against the inner wall of the outer frame 401. Subsequently, through the rotation of the heating cylinder 301, the mask continues to rub against the inner wall of the outer frame 401. This friction process simulates the rubbing action of hand washing, effectively loosening and removing the dirt on the mask. This cleaning method abandons the traditional manual brush, which not only saves cleaning time, but also significantly improves cleaning efficiency;

[0052] In the drying working state:

[0053] The main function of the outer frame 401 is to support the insertion rods 402 and achieve orderly horizontal and vertical overlap, thereby constructing a panel shaped like a "well". This "well" panel is equivalent to a filter plate in function. With the continuous flipping during the drying process, friction is inevitable between the masks and between the masks and the outer wall of the heating cylinder 301, causing some loose fibers and dust to fall off. In order to effectively capture and collect these shed fibers and dust and prevent them from attaching to the mask again or diffusing into the air, we specially designed a lattice mesh structure so that it can play a good capture and collection role when the heating cylinder 301 heats and blows hot air to dry the mask;

[0054] Specifically, the staff first securely places the mask in the interlayer cavity between the outer auxiliary component 400 and the inner auxiliary component 300. Then, the water inlet pipe 202 is started to inject water into the water tank 201 to start the cleaning operation. Next, the driver 406 is started, and its output end begins to rotate, and drives the driving rod 404 to rotate through the transmission action of the belt 407. The rotation of the driving rod 404 further drives the rotation of the rotating shaft 405, thereby driving the outer frame 401 to rotate. The rotation of the outer frame 401 drives the first rotating rod 302 and the heating cylinder 301 to rotate, and the centrifugal force generated during the rotation process makes the mask fit tightly on the inner wall of the outer frame 401. After the mask is fitted, the continuous rotation of the heating cylinder 301 causes the mask to rub against the inner wall of the outer frame 401, simulating the action of hand washing and rubbing. This friction process effectively loosens and removes the dirt on the mask, achieving efficient cleaning of the mask. This cleaning method abandons the traditional manual brush cleaning method, which not only significantly saves cleaning time, but also improves cleaning efficiency. After completing the cleaning operation, the water outlet pipe 203 is immediately started to completely drain the water in the water tank 201. After the water flow is completely discharged, the drying process is immediately started. At this time, the output end of the driving machine 406 performs a reverse action, thereby driving the outer frame 401 and the heating cylinder 301 to rotate in the opposite direction. During this process, the heating cylinder 301 starts to heat and discharge hot air to dry the mask.

[0055] It is worth noting that the inner wall of the outer frame 401 is designed with a panel in the shape of a "well", which is consistent with the function of the filter plate. During the drying process, with the continuous flipping action, a certain amount of friction will inevitably occur between the masks and between the masks and the outer wall of the heating cylinder 301, which may cause some loose fibers and dust to fall off. These shed fibers and dust are thus captured and collected to prevent them from attaching to the mask surface again or diffusing into the surrounding air. This design not only improves the overall work efficiency, but also significantly enhances the convenience of operation.

[0056] Finally, the disturbance component 310 is required to disturb and roll the mask during cleaning, so that different parts of the mask rub against the external auxiliary component 400 and the disturbance component 310 will squeeze the mask during drying, forcing the mask to fit the external auxiliary component 400, and the moisture contained in the mask is discharged through squeezing. Figure 6 and Figure 8The second rotating rod 316 is rotatably connected to the inner wall of the heating cylinder 301, and the outer wall of the second rotating rod 316 is fixedly connected to the column gear 314, and the column gear 314 is meshed with a tooth plate 313, and the upper side of the tooth plate 313 is fixedly connected to the disturbance rod 311, and the lower end of the disturbance rod 311 is rotatably connected to the outer wall of the second rotating rod 316, and the upper end of the disturbance rod 311 passes through the inner wall of the heating cylinder 301 and is fixedly connected to the inclined plate 312. When the inclined plate 312 is cleaning the mask, the heating cylinder 301 rotates forwardly to drive the inclined plate 312 to rotate inside its outer frame 401. At this time, the front of the inclined plate 312 impacts the mask, which produces a disturbance effect on the mask and interweaves the masks piled together, thereby reducing the continued accumulation of masks and causing the masks to roll over. When drying, the heating cylinder 301 rotates in the opposite direction to drive the inclined plate 312 to rotate inside its outer frame 401. At this time, the back of the inclined plate 312 squeezes the mask, exerts a squeezing effect on the mask, squeezes the mask against the inner wall of the outer frame 401, and discharges moisture from the mask. One end of the second rotating rod 316 is rotatably connected to the first rotating rod 302 and the inner wall of the rotating shaft 405, and a groove is provided at one end close to the rotating shaft 405. An opening is provided on the outer wall of the rotating shaft 405 and an elastic block 317 is clamped inside. The upper end of the elastic block 317 abuts against the pulling rod 315, and the lower end of the pulling rod 315 abuts against the upper end of the elastic block 317. The pulling rod 315 squeezes the elastic block 317 by moving downward to insert the elastic block 317 into the clamping groove at one end of the second rotating rod 316, so that the rotating shaft 405 rotates to drive the second rotating rod 316 to rotate, wherein:

[0057] In the cleaning working state:

[0058] The heating cylinder 301 rotates forward, thereby driving the inclined plate 312 to perform circular motion inside the outer frame 401. During this process, the front of the inclined plate 312 directly hits the mask, causing a significant disturbance effect on the mask. At the same time, the inclined plate 312 effectively intersperses the accumulated masks, significantly reducing the further accumulation of the masks and causing the masks to tumble;

[0059] In the drying working state:

[0060] The pull rod 15 exerts pressure on the elastic block 317 through the downward movement, so that it is smoothly inserted into the slot at one end of the second rotating rod 316. Through this operation, the rotating shaft 405 and the second rotating rod 316 are firmly connected. Therefore, when the rotating shaft 405 rotates, due to the connection relationship between it and the second rotating rod 316, it will synchronously drive the second rotating rod 316 to rotate, and the rotation of the second rotating rod 316 will further drive the column gear 314 to rotate. The column gear 314 causes the tooth plate 313 to move by meshing transmission. In the initial state, the tooth plate 313 is in a contracted state, but after the displacement occurs, the tooth plate 313 will extend. This extension process enables the tooth plate 313 to drive the disturbance rod 311 to move upward. Subsequently, the disturbance rod 311 pushes the inclined plate 312 to fit the inner wall of the outer frame 401 more closely, thereby enhancing the effect of the inclined plate 312 in squeezing the mask. Therefore, driven by the reverse rotation of the heating cylinder 301, the inclined plate 312 rotates inside its outer frame 401. During this process, the back of the inclined plate 312 is in close contact with the inner wall of the outer frame 401 and exerts a squeezing effect on the mask, thereby effectively squeezing the mask against the inner wall of the outer frame 401 to discharge moisture from the mask.

[0061] Specifically, when cleaning, the rotation of the outer frame 401 will drive the first rotating rod 302 and the heating cylinder 301 to perform circular motion synchronously. During the rotation process, due to the effect of centrifugal force, the mask is able to fit tightly on the inner wall of the outer frame 401. After the mask is fitted, the continuous rotation of the heating cylinder 301 will cause the mask to rub against the inner wall of the outer frame 401. At the same time, the front of the inclined plate 312 will directly collide with the mask, causing a significant disturbance to the mask. In addition, the inclined plate 312 effectively intersperses the accumulated masks, significantly reducing the further accumulation of the masks and causing the masks to tumble. This tumbling state causes different parts of the mask to rub against the external auxiliary component 400, thereby enhancing the cleaning effect of the mask. When drying, by pulling the pull rod 315, the pull rod 15 moves downward to squeeze the elastic block 317 and inserts the elastic block 317 into the slot at one end of the second rotating rod 316, so that the rotating shaft 405 rotates to drive the second rotating rod 316 to rotate. As the second rotating rod 316 rotates, the column gear 314 is driven to rotate. The column gear 314 causes the tooth plate 313 to move by meshing transmission. In the initial state, the tooth plate 313 is in a contracted state, but as the displacement occurs, the tooth plate 313 will extend. This extension process enables the tooth plate 313 to effectively drive the disturbance rod 311 to move upward. Subsequently, the disturbance rod 311 pushes the inclined plate 312 to fit more closely to the inner wall of the outer frame 401, thereby significantly enhancing the effect of the inclined plate 312 in squeezing the mask.

[0062] Then, the output end of the driving machine 406 performs a reverse action, thereby driving the outer frame 401 and the heating cylinder 301 to rotate in the opposite direction. During this process, the inclined plate 312 rotates inside its outer frame 401. It is worth noting that the back of the inclined plate 312 is in close contact with the inner wall of the outer frame 401 and exerts an effective squeezing effect on the mask. This squeezing process can effectively squeeze the mask against the inner wall of the outer frame 401, thereby effectively draining the moisture inside the mask. This design significantly reduces the time required for drying, thereby improving the drying efficiency.

[0063] In the final stage, in order to ensure the efficiency and accuracy of the cleaning and drying process, the staff can visually observe the working conditions. Therefore, a dust cover 102 is rotatably connected to the upper side of the shell 101. The dust cover 102 is used to ensure the sealing during cleaning and drying. An observation window 103 is provided inside the dust cover 102 for observing the working status during cleaning and drying.

[0064] The specific working principle is:

[0065] The staff first waterproofs the communication device built into the mask, and then securely places it in the interlayer cavity between the outer auxiliary component 400 and the inner auxiliary component 300 to ensure that it is firmly placed. Then, the water inlet pipe 202 is started to inject an appropriate amount of water into the water tank 201 to start the cleaning process. Next, the drive motor 406 is activated, and its output end begins to rotate steadily, and drives the drive rod 404 to rotate synchronously through the transmission mechanism of the belt 407. Under the drive of the drive rod 404, through the meshing transmission connection mechanism, the rotation of the drive rod 404 further drives the rotation of the shaft 405, thereby triggering the rotation of the outer frame 401.

[0066] The rotation of the outer frame 401 drives the first rotating rod 302 and the heating cylinder 301 to rotate. During the rotation, due to the centrifugal force, the mask is tightly attached to the inner wall of the outer frame 401. Subsequently, the continuous rotation of the heating cylinder 301 causes the mask to rub against the inner wall of the outer frame 401 to achieve a cleaning effect on the mask.

[0067] During the cleaning process, the rotation of the outer frame 401 drives the first rotating rod 302 and the heating cylinder 301 to move in a circular motion. At the same time, the front of the inclined plate 312 directly collides with the mask, causing a significant disturbance to the mask, which helps to enhance the cleaning effect. In addition, the inclined plate 312 also effectively intersperses the accumulated masks, reduces the accumulation of masks, and causes the masks to roll over.

[0068] This tumbling state causes friction between different parts of the mask and the external auxiliary component 400, thereby improving the cleaning effect and simulating the rubbing action of hand washing. Through this friction process, the dirt on the mask is effectively loosened and removed, achieving efficient cleaning of the mask. Compared with the traditional manual brush cleaning method, this cleaning method significantly saves cleaning time and improves cleaning efficiency, bringing significant improvements and enhancements to the cleaning work of the mask.

[0069] After the washing operation is completed, the water outlet pipe 203 is immediately started to completely drain the water in the water tank 201. After the water in the water tank 201 is completely drained, the drying process is immediately started. To ensure the smooth progress of the drying process, the pull rod 315 needs to be pulled. The pull rod 15 exerts pressure on the elastic block 317 through the downward movement, prompting it to smoothly insert into the slot at one end of the second rotating rod 316. Through this operation, the rotating shaft 405 and the second rotating rod 316 are firmly engaged. Therefore, when the rotating shaft 405 rotates, due to the engagement relationship between it and the second rotating rod 316, it will synchronously drive the second rotating rod 316 to rotate. As the second rotating rod 316 rotates, the column gear 314 meshed with it also rotates. The column gear 314 drives the tooth plate 313 to produce displacement through meshing transmission. In the initial state, the tooth plate 313 is in a contracted state, but as the displacement occurs, the tooth plate 313 will gradually extend. The extension of the tooth plate 313 effectively drives the disturbance rod 311 to move upward. Subsequently, the disturbance rod 311 pushes the inclined plate 312 to fit more closely to the inner wall of the outer frame 401, which significantly improves the effect of the inclined plate 312 in squeezing the mask.

[0070] During this process, the output end of the driving machine 406 performs a reverse action, thereby driving the outer frame 401 and the heating cylinder 301 to rotate in opposite directions. The heating cylinder 301 starts to heat and discharge hot air to dry the mask. At the same time, the inclined plate 312 rotates inside the outer frame 401, and its back surface is in close contact with the inner wall of the outer frame 401, exerting an effective squeezing effect on the mask to promote the discharge of moisture inside the mask. This design significantly shortens the drying time and improves the drying efficiency.

[0071] It is worth noting that the inner wall of the outer frame 401 is designed with a panel in a "well" shape, which complements the function of the filter plate. During the drying process, as the mask and the heating cylinder 301 are constantly turned over, friction may occur between the masks and between the mask and the outer wall of the heating cylinder 301, causing some loose fibers and dust to fall off. These shed fibers and dust are effectively captured and collected, thereby preventing them from attaching to the mask surface again or diffusing into the surrounding air. This design not only improves the overall work efficiency, but also significantly enhances the convenience of operation.
