[0052] In some embodiments of this application, a mask 100 is provided. Figure 18 This is a structural diagram of a face mask 100, which has an air inlet 110. (Combined with...) Figure 1 The air inlet 110 is connected to the air purification device 200 via a connecting pipe (referred to as the first connecting pipe 510). The air purification device 200 is configured to filter air, and the filtered air flows into the air inlet 110 of the mask 100 through the first connecting pipe 510 for the user to breathe.

[0053] A windbreak is provided at the air inlet 110, such as a windbreak panel structure. The windbreak is configured to block the air flowing into the air inlet 110, preventing the airflow from blowing directly onto the user's face, which helps to improve the wearing comfort of the mask 100.

[0054] A one-way valve is installed at the air inlet 110 to prevent the air exhaled by the user inside the mask 100 from flowing back into the first connecting pipe 510.

[0055] The mask 100 is equipped with an air outlet 120 through which the user's exhaled air is discharged. A one-way valve is installed at the air outlet 120 to prevent unfiltered external air from flowing back into the mask 100.

[0056] The mask 100 of this application does not require an internal filter for filtering air. Instead, it uses an external air purification device 200 to filter and purify the air, thereby reducing the cost of the mask 100.

[0057] Commonly available face masks have three ports. The face mask 100 of this application is used in conjunction with the external air purification device 200. It does not require much structural modification to the existing face mask. Only one port needs to be sealed. Of the remaining two ports, one port is used as an air inlet 110 to connect to the first connecting pipe 510, and the other port is used as an air outlet 120.

[0058] In some embodiments of this application, reference is made to Figure 18The mask 100 is equipped with a megaphone 130. Users can communicate more easily through the megaphone 130 in noisy environments.

[0059] For example, the megaphone 130 is located at a closed interface, which optimizes the design of the existing mask structure, reduces research and development costs, and makes full use of the recessed space at the interface to facilitate the installation of the megaphone 130.

[0060] In some embodiments of this application, reference is made to Figure 18 The mask 100 is equipped with Bluetooth 140 for easy communication. For example, Bluetooth 140 is located at a closed interface, which optimizes the existing mask structure, reduces R&D costs, and makes full use of the recessed space at the interface to facilitate the installation of Bluetooth 140.

[0061] In some embodiments of this application, an air purification device 200 is provided, see reference to Figure 3 and Figure 5 , Figure 3 This is a structural diagram of an air purification device 200. Figure 5 This is a cross-sectional view of an air purification device 200. The air purification device 200 is configured to provide filtered air to the air inlet 110 of the mask 100, as shown in the figure. Figure 1 .

[0062] The air purifier 200 includes a housing 210, which forms the outer contour of the air purifier 200 and has an internal mounting cavity. An air inlet 213 is provided on the housing 210.

[0063] The air purification device 200 includes a filter module 220, which is detachably disposed in the mounting cavity and is configured to filter and purify the air flowing through it.

[0064] The air purification device 200 includes a fan 230 disposed within the mounting cavity, the fan 230 being configured to provide power for air circulation.

[0065] When in operation, the fan 230 starts, and the outside air flows through the air inlet 213 and the filter module 220 in sequence for filtration under the power of the fan 230. The filtered air is then supplied to the air inlet 110 of the mask 100 through the first connecting pipe 510.

[0066] By providing airflow power through the fan 230, the air purification device 200 has an air supply function, which helps to improve the comfort of users wearing masks and solves the problem of breathing difficulties when users wear masks for a long time in the prior art.

[0067] The air purifier 200 is used in conjunction with the mask 100. The air purifier 200 is small in size, can be carried around, and is easy to use.

[0068] The filter module 220 is detachable, allowing users to replace it with a suitable filter module 220 according to their air purification needs, thus expanding the applicability of the air purifier 200 to different environments. For example, the filter module 220 can remove dust, sterilize, deodorize, and dehumidify the air.

[0069] In some embodiments of this application, reference is made to Figure 3 and Figure 5 The housing 210 includes a first housing 211 and a second housing 212, which are detachably connected. An air inlet 213 is provided on the first housing 211 and / or the second housing 212, and the filter module 220 is configured to be installed and removed through the end openings of the first housing 211 and / or the second housing 212.

[0070] In other words, when the filter module 220 needs to be replaced, the first housing 211 and the second housing 212 can be separated first, and then the filter module 220 can be installed or removed, which facilitates the installation and removal of the filter module 220.

[0071] In some embodiments of this application, the filter module 220 includes a first filter element 221, which is detachably disposed within a first housing 211, and an air inlet 213 is provided on the first housing 211.

[0072] Specifically, the first filter element 221 is, for example, a HEPA filter element, which performs primary filtration of the air, filtering out dust and other particles in the air.

[0073] The first housing 211 has an open top, and the first filter element 221 is disposed at the open end of the first housing 211. After the first housing 211 is separated from the second housing 212, the first filter element 221 can be directly removed or inserted from the open top of the first housing 211.

[0074] The first filter element 221 is closely attached to the inner peripheral wall of the first housing 211. There is a certain distance between the first filter element 221 and the bottom wall of the first housing 211. An air intake chamber is formed between the first filter element 221 and the bottom wall of the first housing 211. The air inlet 213 is connected to the air intake chamber, and the air intake chamber plays the role of airflow buffer.

[0075] In some embodiments of this application, reference is made to Figures 5 to 7A limiting sleeve 280 is provided inside the first housing 211. The limiting sleeve 280 is a sleeve structure. An annular first limiting step 216 is provided on the inner peripheral wall of the first housing 211, and an annular second limiting step 281 is provided on the outer peripheral wall of the limiting sleeve 280. The limiting sleeve 280 is fitted onto the inner peripheral wall of the first housing 211. The bottom of the limiting sleeve 280 abuts against the first limiting step 216, and the second limiting step 281 abuts against the top of the first housing 211. In this way, the limiting sleeve 280 is fixedly installed on the first housing 211.

[0076] The inner peripheral wall of the limiting sleeve 280 is provided with an annular third limiting step 282. The first filter element 221 is disposed within the space enclosed by the limiting sleeve 280, and the bottom of the first filter element 221 abuts against the third limiting step 282. That is, the first filter element 221 is installed in the first housing 211 through the limiting sleeve 280.

[0077] In some embodiments of this application, reference is made to Figure 6 and Figure 7 The upper part of the limiting sleeve 280 extends upward from the first housing 211. A buckle 283 is provided on the outer peripheral wall of the limiting sleeve 280. Correspondingly, a groove is provided on the inner peripheral wall of the second housing 212. When the first housing 211 and the second housing 212 are mated, the upper part of the limiting sleeve 280 extends into the second housing 212. Then, the first housing 211 or the second housing 212 is screwed on, causing relative rotation between the first housing 211 and the second housing 212, so that the buckle 283 is screwed into the groove, thereby realizing the mating of the first housing 211 and the second housing 212.

[0078] In some embodiments of this application, the air purification device 200 further includes a locking part 290 disposed between the first housing 211 and the second housing 212 to achieve locking between the first housing 211 and the second housing 212.

[0079] Specifically, refer to Figure 6 A first gap 293 is formed between the limiting sleeve 280 and the first housing 211, and a second gap 294 is formed between the limiting sleeve 280 and the second housing 212. The locking part 290 includes a latch 291, which is disposed near the outer peripheral wall of the limiting sleeve 280. The lower end of the latch extends into the first gap 293, and the upper end extends into the second gap 294.

[0080] The locking part 290 also includes a spring 292, which is disposed between the locking buckle and the first housing 211. The spring 292 is configured to apply a force to the locking buckle so that the spring 292 tends to move toward the second housing 212.

[0081] In some embodiments of this application, the filter module 220 includes a second filter element 222, which is detachably disposed within the second housing 212. After the first housing 211 is separated from the second housing 212, the second filter element 222 can be removed or inserted through the bottom opening of the second housing 212.

[0082] In some embodiments of this application, the second filter element 222 is one or a combination of adsorption filter elements, sterilization filter elements, deodorization filter elements, dehumidification filter elements, dust removal filter elements, and high-efficiency activated carbon filter elements, to meet users' different purification needs for ambient air. The adsorption filter element can be an adsorption material such as molecular sieve or fiber.

[0083] In some embodiments of this application, the second filter element 222 is an adsorption module, which achieves adsorption and filtration of the air flowing through it. After the adsorption module has been used for a period of time, it is removed and regenerated by the adsorption module desorption device 300, thus realizing the recycling of the adsorption module.

[0084] The adsorption module described above can be an adsorption material such as a molecular sieve or fiber.

[0085] In some embodiments of this application, reference is made to Figure 5 The fan 230 is installed inside the second housing 212 along the gas flow direction. The fan 230 is located downstream of the second filter element 222. The air outlet 231 of the fan 230 is connected to the air inlet 110 of the mask 100 through the first connecting pipe 510.

[0086] In other words, the second filter element 222 is installed in the lower part of the cavity of the second housing 212, and the fan 230 is installed in the upper part of the cavity of the second housing 212. The layout is reasonable and the structure is compact.

[0087] In some embodiments of this application, reference is made to Figure 3 The second housing 212 is a split structure, comprising a second housing 212Ⅰ and a second housing 212Ⅱ, which are detachably connected by screws, clips, or other means. The second filter element 222 is disposed within the second housing 212Ⅰ, and the fan 230 is disposed within the second housing 212Ⅱ.

[0088] When the second housing 212 adopts a split structure, the second housing 212Ⅰ can be flexibly selected to have an air inlet hole or not, depending on the type of the internal second filter element 222.

[0089] Figure 3 In this configuration, the second housing 212Ⅰ does not have an air inlet. For example, when the second filter element 222 is an adsorption module, the second housing 212Ⅰ adopts... Figure 3 The structure shown is without an air inlet hole.

[0090] Figure 4In the middle, the second housing 212Ⅰ has an air inlet vent 214. For example, when the second filter element 222 is a plate filter such as a HEPA filter, the second housing 212Ⅰ adopts... Figure 4 The structure shown has an air inlet hole 214.

[0091] In some embodiments of this application, reference is made to Figure 5 The air purifier 200 also includes a battery 240. The battery 240 is a rechargeable battery. The battery 240 is positioned above the fan 230 to make full use of space.

[0092] In some embodiments of this application, reference is made to Figure 5 The air purification device 200 also includes a controller 250, which is positioned above the battery 240 to make full use of space.

[0093] In some embodiments of this application, reference is made to Figure 3 An indicator light 260 is provided on the housing 210. For example, the indicator light 260 is located at the top of the housing 210. Since the controller 250 is located on top, the indicator light 260 is located at the top to facilitate connection with the controller 250.

[0094] Indicator light 260 is used as an alarm indicator light 260. For example, an air quality detection sensor is installed at the air outlet 231 of the air purifier 200. When the output air quality is detected to be substandard, the controller 250 controls indicator light 260 to light up, reminding the user to replace the filter module 220 in time.

[0095] In some embodiments of this application, reference is made to Figure 3 The air purifier 200 also includes an airflow adjustment button 270. The airflow adjustment button 270 is located on the top of the housing 210, near the controller 250, for easy connection to the controller 250. The airflow of the fan 230 can be adjusted using the airflow adjustment button 270 to meet different user needs.

[0096] In some embodiments of this application, the housing 210 is provided with a hook 215, which is configured to connect a rope to allow the air purifier 200 to be worn by a user for easy carrying. Hooks 215 are provided at the top and bottom of the housing 210, respectively.

[0097] In some embodiments of this application, the air purification device 200 is connected to the air inlet of the respiratory protective equipment via a first connecting pipe 510 to provide clean air to the user. For example, the respiratory protective equipment is... Figure 18 The mask shown is 100. Another example is a welding mask, which is a respiratory protective device.

[0098] In some embodiments of this application, an adsorption module desorption device 300 is provided, configured to desorb and regenerate an adsorption module 340. Figure 8 This is a structural diagram of an adsorption module desorption device 300. Figure 9 This is a cross-sectional view of the adsorption module desorption device 300. When the air purification device 200 described above uses the adsorption module 340, after the adsorption module 340 has been used for a period of time, it becomes saturated with adsorption. The adsorption module 340 is then removed, and the adsorption module desorption device 300 is used to desorb and regenerate the adsorption module 340, thereby realizing the recycling of the adsorption module 340.

[0099] Since the air purifier 200 is portable and designed for use with the mask 100, its size is small, and the adsorption module 340 is correspondingly small as well. Currently, most desorption devices are designed for large industrial adsorption modules 340; there is no device specifically for desorption of small adsorption modules 340. Therefore, it is necessary to develop an adsorption module desorption device 300 suitable for this application scenario.

[0100] Reference Figure 8 and Figure 9 The adsorption module desorption device 300 includes an upper module 310. Figure 13 This is a structural diagram of the upper module 310. Figure 14 This is a cross-sectional view of the upper module 310. An air guide cavity 313 is provided inside the upper module 310, and a heating element 314 is provided within the air guide cavity 313. For example, the heating element 314 is a heating wire or a heating rod, used to heat the flowing air.

[0101] The adsorption module desorption device 300 includes a lower module 320. The lower module 320 has a placement seat 322 inside, which is configured to place the adsorption module 340. Figure 10 This is a structural diagram of the lower module 320 without the adsorption module 340 placed therein. Figure 11 This is a structural diagram of a lower module 320 in which an adsorption module 340 is placed. Figure 12 This is a cross-sectional view of the lower module 320.

[0102] The adsorption module desorption device 300 includes a lifting part 330, which is disposed between the upper module 310 and the lower module 320. The lifting part 330 is configured to drive the upper module 310 and the lower module 320 to move closer to or further away from each other. For example, the lifting part 330 drives the upper module 310 to rise or fall.

[0103] In this process, the gas is heated by the air guide cavity 313 and the heating part 314, and the heated gas flows through the adsorption module 340 to desorb the adsorption module 340.

[0104] Specifically, when desorption of the adsorption module 340 is required, the lifting unit 330 is first activated, driving the upper module 310 to rise, separating it from the lower module 320. The adsorption module 340 to be desorbed is then placed on the placement seat 322. Next, the lifting unit 330 drives the upper module 310 to descend, bringing it into contact with the lower module 320. The fan 230 and heating unit 314 are turned on, allowing external air to flow through the air guide cavity 313, through the heating unit 314, and then through the adsorption module 340, using hot air to desorb and regenerate the adsorption module 340. After the equipment has been running for a period of time, the heating unit 314 is turned off, and the fan 230 continues to run for a period of time to cool the adsorption module 340. Finally, the lifting unit 330 drives the upper module 310 to rise, removing the desorbed and regenerated adsorption module 340.

[0105] The adsorption module desorption device 300 has a split structure, with an upper module 310 containing an air guide cavity 313 and a heating element 314 for guiding and heating the gas. The lower module 320 houses the adsorption module 340, which is desorbed and regenerated using heated air. The upper module 310 is raised or lowered via a lifting element 330, facilitating the removal and insertion of the adsorption module 340.

[0106] Multiple adsorption modules 340 can be placed in the lower module 320 at the same time to achieve simultaneous desorption and regeneration of multiple adsorption modules 340.

[0107] In some embodiments of this application, reference is made to Figure 14 The air guide cavity 313 includes multiple sub-air guide cavities 3132, and a heating element 314 is provided in each sub-air guide cavity 3132. Specifically, the sub-air guide cavity 3132 has a cone-shaped structure that is narrow at the top and wide at the bottom, and the heating element 314 is located inside the sub-air guide cavity 3132.

[0108] Reference Figure 9 and Figure 12 The placement seat 322 is provided with multiple placement holes 323, which are connected vertically. The adsorption module 340 is placed on the placement holes 323. The multiple placement holes 323 are arranged one-to-one with multiple sub-air guide chambers 3132 so that the gas flowing out of the sub-air guide chambers 3132 flows through the corresponding adsorption module 340.

[0109] By setting multiple sub-air guide chambers 3132 and multiple placement holes 323 in a one-to-one correspondence, after the upper module 310 and the lower module 320 are closed, the air in any sub-air guide chamber 3132 can all flow through the corresponding adsorption module 340, so that each adsorption module 340 can achieve effective air desorption, and the heated air in the sub-air guide chamber 3132 can be effectively utilized, thereby improving the desorption efficiency of the adsorption module 340.

[0110] The heating element 314 is placed in the inner cavity of the sub-air guide cavity 3132 to effectively heat the air flowing through it and improve heating efficiency.

[0111] Figure 10 The lower module 320 shown has six placement holes 323, which can simultaneously desorb and regenerate six adsorption modules 340. If the number of adsorption modules 340 to be desorbed by the user is less than the number of placement holes 323, then during desorption, a block is placed on the placement hole 323 where no adsorption module 340 is placed to prevent gas from flowing through the air guide cavity 3132 in that air path, and the heating part 314 in that air path is also turned off.

[0112] In some embodiments of this application, reference is made to Figure 14 The air guide cavity 313 also includes an air distribution cavity 3131, which is connected to multiple sub-air guide cavities 3132. The air distribution cavity 3131 is located upstream of the sub-air guide cavities 3132, and external gas flows through the air distribution cavity 3131 and the sub-air guide cavities 3132 in sequence.

[0113] The air distribution chamber 3131 plays a role in equalizing the flow. Under the action of the fan 230, the external gas first flows into the air distribution chamber 3131, and then flows from the air distribution chamber 3131 into multiple sub-air guide chambers 3132.

[0114] In some embodiments of this application, reference is made to Figure 8 and Figure 14 The upper module 310 includes an upper housing 311, on which an air inlet 315 is provided. The interior of the upper housing 311 is divided into an outer cavity 312 and an inner cavity by a partition. The air inlet 315 communicates with the outer cavity 312. The inner cavity is provided with an air distribution cavity 3131 and a sub-air guide cavity 3132. The air distribution cavity 3131 communicates with the outer cavity 312 through an air duct (not shown). A fan (not shown) is installed inside the air duct.

[0115] During desorption, under the action of the fan, external air flows into the outer cavity 312 through the air inlet 315, then into the air distribution cavity 3131 through the air duct, and then flows to the adsorption module 340 after being heated by the sub-air guide cavity 3132.

[0116] In some embodiments of this application, reference is made to Figure 14 The sub-air guide cavity 3132 has an opening with a perforated plate 316 on the side facing the adsorption module 340. The perforated plate 316 limits the adsorption module 340, preventing it from touching the heating part 314 upwards. At the same time, the perforated plate 316 also serves to equalize the airflow.

[0117] In some embodiments of this application, reference is made to Figure 12The lower module 320 includes a lower housing 321, an exhaust gas chamber 324 is provided inside the lower housing 321, and an exhaust gas outlet 325 connected to the exhaust gas chamber 324 is also provided on the lower housing 321. The exhaust gas after being desorbed by the adsorption module 340 flows into the exhaust gas chamber 324 and is then discharged through the exhaust gas outlet 325.

[0118] The waste gas chamber 324 is used to collect and discharge the desorbed waste gas in a centralized manner, which facilitates connection with the waste gas treatment device 400 for centralized treatment of the waste gas.

[0119] In some embodiments of this application, the top wall of the exhaust gas chamber 324 serves as a placement seat 322, and the placement seat 322 is provided with a plurality of placement holes 323. The adsorption module 340 is placed on the placement holes 323, and the placement holes 323 are connected to the exhaust gas chamber 324.

[0120] The exhaust gas chamber 324 serves both to collect exhaust gas and to house the adsorption module 340, integrating multiple functions and featuring a compact structure.

[0121] In some embodiments of this application, reference is made to Figure 11 The lifting part 330 is an electric lifting push rod, which includes a motor 331 and a push rod 332. The motor 331 is mounted on the upper module 310, and one end of the push rod 332 is connected to the motor 331 and the other end is connected to the lower module 320.

[0122] Two electric lifting push rods 332 are provided and arranged on the left and right sides of the upper module 310 to improve the reliability of the lifting movement of the upper module 310.

[0123] In some embodiments of this application, the lower housing 321 is provided with heat dissipation holes 326 for heat dissipation.

[0124] In some embodiments of this application, the lower housing 321 is provided with handle positions 327 on the left and right sides respectively, which facilitates hand-holding to carry the adsorption module desorption device 300.

[0125] In some embodiments of this application, a waste gas treatment device 400 is provided. Figure 15 and Figure 16 This is a structural diagram of the waste gas treatment device 400 viewed from different sides. Figure 17 This is a cross-sectional view of the waste gas treatment device 400.

[0126] Reference Figure 2 The waste gas treatment device 400 is connected to the waste gas outlet 325 of the adsorption module desorption device 300 via a pipeline (denoted as the second connecting pipeline 520) for centralized treatment of waste gas. The waste gas treatment device 400 is a catalytic combustion device.

[0127] Specifically, the waste gas treatment device 400 includes a housing 410. The housing 410 is provided with a waste gas inlet 411 and an exhaust port 412. The waste gas inlet 411 is connected to the waste gas outlet 325 of the adsorption module desorption device 300 through a second connecting pipe 520.

[0128] The exhaust gas treatment device 400 includes a heating chamber 420, which is disposed within the inner cavity of the outer casing 410. The heating chamber 420 is configured to heat the incoming exhaust gas. Specifically, the heating chamber 420 is connected to the exhaust gas inlet 411, and a heating element 421 is disposed within the heating chamber 420. The exhaust gas first flows into the heating chamber 420, where the heating element 421 heats it. In actual operation, the heating element 421 is first activated for preheating. Only when the heating element 421 reaches a set temperature, such as 300°C, does the exhaust gas begin to flow into the heating chamber 420. The heating element 421 is, for example, a heating rod.

[0129] The exhaust gas treatment device 400 includes a combustion chamber 430, which is connected to a heating chamber 420. A catalyst 431 is disposed within the combustion chamber 430 and configured to decompose the flowing exhaust gas. The combustion chamber 430 is connected to an exhaust port 412. After being heated in the heating chamber 420, the exhaust gas flows into the combustion chamber 430. The heated exhaust gas then passes through the catalyst 431, where a catalytic reaction occurs, converting the gas into carbon dioxide and water.

[0130] In some embodiments of this application, reference is made to Figure 16 The outer casing 410 is provided with a heat dissipation perforated plate 422. An installation chamber is provided on the end side of the heating chamber 420, and one end of the heating rod is located in the installation chamber. The heat dissipation perforated plate 422 serves as a side wall of the installation chamber to dissipate heat from the installation chamber.

[0131] In some embodiments of this application, the exhaust gas treatment device 400 further includes a control box. A cooling fan 440 is provided on the housing 410, and the cooling fan 440 is used to dissipate heat from the control box.

[0132] In some embodiments of this application, an air purification system is provided, with reference to... Figure 1 and Figure 2 This includes:

[0133] Mask 100, which has an air inlet 110 and an air outlet 120;

[0134] The air purifier 200 is equipped with an adsorption module 340 and a fan 230. The adsorption module 340 is configured to adsorb and filter the air flowing through it, and the fan 230 is configured to provide air circulation power. The air outlet 231 of the air purifier 200 is connected to the air inlet 110 of the mask 100 through a first connecting pipe 510. The air purifier 200 is configured to be portable.

[0135] The adsorption module desorption device 300 has multiple placement holes 323 for placing adsorption modules 340 inside. The adsorption module desorption device 300 is configured to desorb multiple adsorption modules 340 at the same time.

[0136] The waste gas treatment device 400 is connected to the waste gas outlet 325 of the adsorption module desorption device 300 via a second connecting pipe 520. The waste gas treatment device 400 is configured to centrally treat waste gas.

[0137] The air purification system of this application is suitable for environments containing volatile organic compounds (VOCs), bacteria, viruses, dust, welding fumes, or foul odors. When working in these environments, users wear a mask 100 and an air purification device 200 to ensure safe breathing. The air purification device 200 is equipped with a fan 230 to improve airflow and enhance the comfort of the mask 100, preventing breathing difficulties. The adsorption module 340 can be periodically desorbed and regenerated using a dedicated adsorption module desorption device 300, achieving recycling and reducing operating costs. The adsorption module desorption device 300 can simultaneously desorb multiple adsorption modules 340, improving desorption efficiency. The waste gas treatment device 400 is used in conjunction with the adsorption module desorption device 300 to achieve centralized treatment of waste gas, preventing environmental pollution.

[0138] Since the mask 100 and the air purifier 200 are worn on the body, and the air purifier 200 is small in size, the adsorption module 340 is also small in size. Therefore, the applicant has specifically developed an adsorption module desorption device 300 and an exhaust gas treatment device 400 to be used in conjunction with the air purifier 200, so as to improve the convenience of use for users and realize the whole process of air treatment.
