[0002] In related technologies, the disinfection and humidification module in an air purification device includes a water tank, a water trough, and an electrolysis module located within the water trough. The water tank and the water trough are connected. During use, salt granules (sodium chloride) are added to the water trough, and water is poured into the trough through the water tank to form a brine solution (sodium chloride solution). The electrolysis module then electrolyzes the brine solution into a disinfectant solution (sodium hypochlorite solution), which is then blown out by a fan to humidify and disinfect the air. After completing the electrolytic disinfection process, the water trough needs to be cleaned promptly; otherwise, salt accumulation will increase the disinfectant concentration and bacteria will easily grow in the trough. In actual use, users have to clean the water trough every time they add water, resulting in frequent operation and reduced user satisfaction. Summary of the Invention

[0048] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0052] This invention proposes an air purification device 100.

[0053] Please refer to Figure 4 and Figure 8 In one embodiment of the present invention, the air purification device 100 includes a humidification module, which includes a water tank 11, an electrolysis module 12, a waste liquid tank 13, and a conveying assembly 14. The electrolysis module 12 is used to electrolyze the solution in the water tank 11; the waste liquid tank 13 is used to collect the waste liquid generated by the water tank 11; and the conveying assembly 14 is disposed between the water tank 11 and the waste liquid tank 13 to convey the waste liquid in the water tank 11 to the waste liquid tank 13.

[0054] The technical solution of this invention uses an electrolysis module 12 to electrolyze the solution in the water tank 11 to form a disinfectant solution for disinfection. After the disinfection operation is completed, the waste liquid in the water tank 11 is transported to the waste liquid tank 13 for collection via a conveying component 14. This avoids the accumulation of salt in the waste liquid in the water tank 11, which would increase the concentration of the disinfectant solution, and also prevents the growth of bacteria in the water tank 11. Users only need to empty the waste liquid in the waste liquid tank 13 periodically, eliminating the need to clean the water tank 11 before each disinfection, effectively reducing the frequency of cleaning the water tank 11 and improving user satisfaction.

[0055] Furthermore, such as Figure 2 As shown, the air purification device 100 also includes a water tank 15 and a liquid level sensor. The water tank 15 is located in the water tank 11 and is used to supply solution to the water tank 11. The liquid level sensor is used to detect the liquid level in the water tank 11 and sends a signal when the liquid level in the water tank 11 is lower than a preset value. The conveying component 14 starts the waste liquid conveying operation according to the signal.

[0056] Specifically, the water tank 15 is detachably installed inside the water tank 11, and the bottom of the water tank 15 has a liquid outlet opposite to the water tank 11. During disinfection operations, the water tank 15 continuously supplies solution to the water tank 11 through the liquid outlet, at which time the liquid level in the water tank 11 is at a relatively high level. The liquid level in the water tank 11 is detected in real time by a liquid level sensor. When the liquid level sensor detects that the liquid level in the water tank 11 is lower than a preset value, it indicates that the water tank 15 is in a state of low liquid and can no longer continuously supply solution to the water tank 11. At this time, the liquid level sensor sends a signal, and the conveying component 14 starts the waste liquid conveying operation according to the signal, thereby conveying the remaining waste liquid in the water tank 11 to the waste liquid tank 13. The liquid level sensor includes, but is not limited to, contact liquid level sensors or non-contact liquid level sensors for liquid level detection, such as capacitive liquid level sensors, float liquid level sensors, photoelectric liquid level sensors, etc. The water tank 15 can be used to store aqueous solutions. Salt particles are added to the water tank 11 beforehand. Water from the water tank 15 is poured into the water tank 11, and the salt particles dissolve to form a salt solution (e.g., sodium chloride solution). Then, under the action of the electrolysis module 12, it is electrolyzed into a disinfectant (e.g., sodium hypochlorite solution). Alternatively, the water tank 15 can also be used to store pre-prepared salt solutions. The salt solution in the water tank 15 is poured into the water tank 11, and then under the electrolysis action of the electrolysis module 12 in the water tank 11, a disinfectant is generated.

[0057] Optionally, a valve assembly can be provided at the outlet of the water tank 15. When solution needs to be added to the water tank 11, the valve assembly opens the outlet of the water tank 15; when disinfection is complete, the valve assembly closes the outlet of the water tank 15. By controlling the opening and closing of the outlet of the water tank 15 through the valve assembly, the injection of solution into the water tank 15 into the water tank can be controlled in a timed and quantitative manner. Specifically, the valve assembly can be a manual control valve or an electric control valve, with an electric control valve being more preferred.

[0058] Optionally, the air purification device 100 also includes an alarm module electrically connected to a liquid level sensor. When the liquid level in the water tank 11 is lower than a preset value, the alarm module issues an alarm based on the signal from the liquid level sensor, reminding the user that the water tank 15 is low on liquid. The user can then refill the water tank 15 with solution and remove the waste liquid tank 13 to empty the waste liquid. Specifically, the alarm module may include a buzzer for emitting a light signal and / or an indicator light for emitting an audible signal to provide an alarm reminder to the user. Furthermore, to facilitate the user's removal of the water tank 15 and waste liquid tank 13, optionally, both the water tank 15 and waste liquid tank 13 are provided with handles. For example, in this embodiment, the water tank 15 has a handle on its top, and the waste liquid tank 13 has a handle on its side. Optionally, the water tank 15 also has a material inlet separate from the liquid outlet, through which materials (such as solid salt particles and water) can be easily added to the water tank 15 to prepare a salt solution. It is understood that in other embodiments, the material inlet can also be omitted, and the material can be directly added through the liquid outlet of the water tank 15.

[0059] Furthermore, such as Figure 9 As shown, the waste liquid tank 13 is located within the water tank 11. Specifically, in this embodiment, the water tank 11 has a recessed cavity that fits the bottom of the waste liquid tank 13. Placing the waste liquid tank 13 within this recessed cavity, the recessed cavity helps prevent the waste liquid tank 13 from moving left or right. Since the waste liquid tank 13 is located within the water tank 11, any overflowing waste liquid will still flow into the water tank 11, thus preventing the waste liquid from spilling outside the water tank 11 and preventing corrosion of other components of the air purification device 100.

[0060] Further, please refer to Figure 8 and Figure 10 In this embodiment, the conveying assembly 14 includes a first bracket 141, a pump body 142, and a power component 143. The pump body 142 is installed in the water tank 11 through the first bracket 141. The power component 143 is located on the outside of the water tank 11 and is correspondingly arranged with the pump body 142. The power component 143 and the pump body 142 transmit power through magnetic transmission.

[0061] Specifically, the first bracket 141 extends vertically, and its bottom is installed inside the water tank 11. The portion of the first bracket 141 located inside the water tank 11 has a mounting through hole for mounting the pump body 142. The water inlet end of the pump body 142 is accommodated within the mounting through hole, while the side of the pump body 142 facing away from the water inlet end is in close contact with the inner wall of the water tank 11. A power component 143 is located outside the water tank 11, corresponding to the pump body 142, and separated from the pump body 142 by the side wall of the water tank 11. Specifically, the power component 143 can be a water pump motor, and the power is transmitted magnetically between the water pump motor and the pump body 142 to ensure that the pump body 142 can extract waste liquid from the water tank 11 and transport it to the waste liquid tank 13. In this embodiment, by separating the power component 143 from the pump body 142, it is possible to prevent the high-concentration salt solution in the water tank 11 from corroding the power component 143, thereby extending its service life. Furthermore, since the water tank 11 and pump body 142 need to be removed for cleaning periodically, and the power component 143 typically requires an external power cord, separating the power component 143 from the pump body 142 prevents the external power cord from affecting the ease of removal of the pump body 142 and the water tank 11, thus facilitating cleaning by the user. Optionally, the surface of the first bracket 141 may be coated with an anti-corrosion coating to prevent corrosion from prolonged immersion in the water tank 11, thereby extending its service life.

[0062] Furthermore, such as Figure 7 As shown, the water tank 11 has a receiving cavity 111, and the first bracket 141 is detachably installed in the receiving cavity 111. The first bracket 141 and the water tank 11 are detachably connected by means including, but not limited to, plug-in, snap-fit, or fastener connections. In this embodiment, by making the first bracket 141 detachable from the water tank 11, it is easy to remove the first bracket 141 for cleaning, and it also facilitates the cleaning of the pump body 142 on the first bracket 141, effectively improving the cleaning convenience of the first bracket 141 and the pump body 142.

[0063] Furthermore, please combine Figure 8 and Figure 10In this embodiment, the first bracket 141 is provided with a first positioning part 1411, and the water tank 11 is provided with a first mating part 112. The first positioning part 1411 and the first mating part 112 are positioned and engaged to restrict the movement of the first bracket 141 in the vertical plane. Specifically, when the first bracket 141 is installed from top to bottom in the receiving cavity 111 of the water tank 11, the first positioning part 1411 on the first bracket 141 and the first mating part 112 on the water tank 11 are positioned and engaged, thereby restricting the movement of the first bracket 141 in the vertical plane, ensuring that the first bracket 141 will not move in the up, down, left, and right directions, and ensuring the installation stability of the first bracket 141.

[0064] It should be noted that there are various positioning and engagement methods between the first positioning part 1411 of the first bracket 141 and the first mating part 112 of the water tank 11, including but not limited to snap-fit ​​positioning and engagement, plug-in positioning and engagement, etc. Furthermore, the installation positions of the first positioning part 1411 and the first mating part 112 can also be interchanged. For example, as... Figure 8 As shown, in this embodiment, the first support 141 is a long strip extending vertically, and the cross-section of the first support 141 is generally U-shaped. The first support 141 includes a support plate and two side plates disposed on opposite sides of the support plate in the width direction. The water tank 11 has a first side wall that is opposite to and spaced apart from the support plate. The pump body 142 is fixed to the side of the support plate near the first side wall, and the pump body 142 is located between the two side plates. The side of the support plate facing the first side wall is provided with a first positioning part 1411. The first positioning part 1411 includes an extension arm extending toward the first side wall and a bent plate that bends vertically from the end of the extension arm away from the support plate. The side of the bent plate near the first side wall is provided with a locking protrusion. The top surface of the first side wall is provided with a first mating part 112, and the first mating part 112 is provided with a locking groove that matches the locking protrusion. After the first bracket 141 is installed from top to bottom into the receiving cavity 111 of the water tank 11, the locking protrusion of the first positioning part 1411 engages with the locking groove of the first mating part 112, thereby limiting the movement of the first bracket 141 in four directions: top, bottom, left, and right. It is understood that in other embodiments, locking protrusions may be provided on the side wall of the water tank 11, and locking grooves may be provided on the first bracket 141, achieving the same limiting effect. All of these are within the scope of protection of this invention and will not be elaborated further here.

[0065] Furthermore, to enhance the structural strength of the first support 141, the first support 141 also includes reinforcing ribs, which connect the support plate and the side plate. Optionally, multiple reinforcing ribs are provided, and the multiple reinforcing ribs are arranged vertically at intervals within the cavity formed by the support plate and the side plate. For example, as... Figure 8As shown, in this embodiment, each reinforcing rib is generally U-shaped, with its two side sections connected to the side plates and its middle section connected to the support plate, giving the first bracket 141 high structural strength. Optionally, the first bracket 141 is a one-piece molded structure.

[0066] Furthermore, such as Figure 6 As shown, the inner wall of the water tank 11 is provided with a stop portion 113, which is used to horizontally restrict the first bracket 141 within the receiving cavity 111. Specifically, as... Figure 7 As shown, the water tank 11 has a second sidewall adjacent to the first sidewall. The inner surface of the second sidewall is provided with a stop portion 113, which is a vertically extending elongated strip. When the first support 141 is installed inside the water tank 11, the first sidewall and the stop portion 113 can restrict the horizontal movement of the first support 141, preventing it from moving back and forth. The horizontal and vertical directions can be referenced... Figure 10 As indicated by the middle arrow.

[0067] In the above embodiment, since the pump body 142 and the power component 143 are designed separately, and power is transmitted between them through magnetism, the fitting dimensions between them are required to be precise. The first positioning part 1411 and the first mating part 112 of the water tank 11 are positioned and fitted together, limiting the movement of the first support 141 in four directions: up, down, left, and right. Simultaneously, the inner wall of the water tank 11 is provided with a stop part 113 to limit the horizontal movement of the first support 141. This ensures that the first support 141 remains fixed in all directions (up, down, left, right, front, and back), thereby ensuring the fitting precision between the pump body 142 and the power component 143. This allows the power of the power component 143 to be precisely transmitted to the pump body 142 via magnetism, ensuring the operational stability of the pump body 142.

[0068] Further, please refer to Figure 8 and Figure 9The conveying assembly 14 further includes a water pipe 144, one end of which is connected to the output end of the pump body 142, and the other end of which is provided with a water outlet 145. The waste liquid tank 13 is provided with a recovery port 131 to recover the waste liquid output from the water outlet 145. Specifically, the inlet end of the water pipe 144 is connected to the output end of the pump body 144, and the outlet end of the water pipe 144 extends upward along the height direction of the first support 141, which provides support for the water pipe 144. When it is necessary to collect the waste liquid in the water tank 11, the power component 143 drives the pump body 142 to work. The pump body 142 draws out the waste liquid in the water tank 11 and conveys it upward along the water pipe 144 to the water outlet 145. Finally, it is output through the water outlet 145 and falls into the waste liquid tank 13 from the recovery port 131 for collection. Optionally, the waste liquid tank 13 is provided with a collection port 131 at its top, and the water outlet 145 is located above the collection port 131. Optionally, the water outlet 145 is inclined from top to bottom. By positioning the water outlet 145 above the waste liquid tank 13 and tilting it, the waste liquid tank 13 can completely collect the waste liquid output from the water outlet 145, and it is also convenient to remove the waste liquid tank 13 from the water tank 11.

[0069] Further, please refer to Figure 4 and Figure 5 The humidification module also includes a second bracket 16. One side of the second bracket 16 is provided with a accommodating cavity for accommodating the water tank 11 and the waste liquid tank 13, and an opening for the water tank 11 and the waste liquid tank 13 to be pulled out in the horizontal direction. The power component 143 is installed on the second bracket 16.

[0070] Specifically, the second bracket 16 can be fixedly installed inside the housing 20 of the air purifier 100 using fasteners (such as screws, bolts, etc.). The second bracket 16 can be made of sheet metal or plastic. Figure 6 As shown, the second bracket 16 includes a vertically placed partition, a top plate extending from the top of the partition to one side, and a side plate extending downward from one side of the top plate. The side plate is located above the second side wall of the water tank 11. The partition, top plate, and side plate together form an accommodating cavity. The second bracket 16 also includes a back plate connected to the side plate. The back plate is located outside the first side wall of the water tank 11, and the power component 143 is installed on the back plate by fasteners. When it is necessary to remove the water tank 11 and waste liquid tank 13 from the body of the air purifier 100, the water tank 11 and waste liquid tank 13 can simply be pulled out horizontally from the opening. The second bracket 16 not only serves to install the power component 143, but also acts as a partition to separate the water tank 11 from other components inside the air purifier 100. For example, the fan 19 of the air purifier 100 can be arranged on the side of the partition away from the water tank 11.

[0071] Furthermore, please combine Figure 8 and Figure 11 The second support 16 is provided with a second positioning part 161, and the water tank 11 is provided with a second mating part 114. The second positioning part 161 and the second mating part 114 are positioned and mated to restrict the movement of the second support 16 in the vertical plane. Specifically, in this embodiment, the second positioning part 161 is a protrusion extending toward the first wall surface of the water tank 11, and the second mating part 114 is a groove provided on the outer side of the first wall surface of the water tank 11. The protrusion is inserted into the groove, and the four walls of the groove limit the protrusion, thereby limiting the second support 16 in the four directions of up, down, left, and right, ensuring the fitting accuracy between the power component 143 and the pump body 142, while not affecting the extraction of the water tank 11 in the front-back direction. It can be understood that the positions of the second positioning part 161 and the second mating part 114 can be interchanged.

[0072] Furthermore, such as Figure 12 As shown, the humidification module also includes a third bracket 17 movably connected to the second bracket 16. The electrolysis module 12 is installed on the third bracket 17. The third bracket 17 has a first position and a second position relative to the second bracket 16. In the first position, the electrolysis module 12 is inserted into the water tank 11. In the second position, the electrolysis module 12 is separated from the water tank 11.

[0073] Specifically, the third support 17 is used to fix the electrolysis module 12. The third support 17 and the second support 16 are connected by means of, but not limited to, sliding or rotating connections. For example, in this embodiment, the third support 17 and the second support 16 are slidably connected, allowing the third support 17 to slide between a first position and a second position; or, for example, the third support 17 and the second support 16 are rotatably connected, allowing the third support 17 to rotate between a first position and a second position. As long as the movement of the third support 17 can drive the electrolysis module 12 to be inserted into or removed from the water tank 11, no specific limitation is made here. When it is necessary to electrolyze the solution in the water tank 11, the third support 17 moves relative to the second support 16 to the first position, at which time the electrolysis module 12 is inserted into the water tank 11, thereby enabling normal electrolysis of the solution in the water tank 11. When the water tank 11 needs to be pulled out, the third bracket 17 moves to the second position relative to the second bracket 16. At this time, the electrolysis module 12 is separated from the water tank 11, so that it will not interfere with the extraction of the water tank 11 and ensure that the water tank 11 can be pulled out smoothly.

[0074] Furthermore, such as Figure 11As shown, the second bracket 16 has a receiving cavity on the side opposite to the accommodating cavity for accommodating the third bracket 17. The receiving cavity has an inlet and outlet 162 opposite to the water tank 11, and the electrolysis module 12 can extend into the water tank 11 from the inlet and outlet 162. Placing the third bracket 17 in the receiving cavity makes the assembly structure between the third bracket 17 and the second bracket 16 more compact and occupies less space.

[0075] Furthermore, the third bracket 17 is slidably mounted on the second bracket 16. The second bracket 16 is provided with a limiting part 163, and the third bracket 17 is provided with a toggle buckle 171. In the second position, the toggle buckle 171 is locked with the limiting part 163. Specifically, when it is necessary to pull out the water tank 11, the user only needs to move the toggle buckle 171 to move the third bracket 17 to the second position, and then lock the toggle buckle 171 with the limiting part 163 on the second bracket 16 to keep the third bracket 17 in the second position, so that the user can free up his hand to pull out the water tank 11.

[0076] Furthermore, such as Figure 11 As shown, the second bracket 16 has a vertically extending guide groove 164. The actuating buckle 171 is slidably inserted into the guide groove 164, and the limiting part 163 is located at the upper end of the guide groove 164. The sliding engagement between the guide groove 164 and the actuating buckle 171 guides the movement of the actuating buckle 171. When the actuating buckle 171 moves to the lower end of the guide groove 164, the guide groove 164 limits the movement of the actuating buckle 171, at which point the second bracket 16 remains in the first position, and the electrolysis module 12 can be inserted into the water tank 11. When the actuating buckle 171 is moved upwards along the guide groove 164 to the upper end of the guide groove 164, the actuating buckle 171 locks with the limiting part 163, at which point the second bracket 16 remains in the second position.

[0077] Furthermore, such as Figure 12 As shown, one of the third support 17 and the second support 16 is provided with a vertically extending groove 172, and the other is provided with a limiting post 165 that slides with the groove 172. The cooperation between the groove 172 and the limiting post 165 enables a sliding connection between the third support 17 and the second support 16, and at the same time, the groove 172 also guides the sliding of the third support 17.

[0078] For example, in this embodiment, the second bracket 16 is provided with a horizontally extending limiting post 165, and the third bracket 17 is provided with a vertically extending sliding groove 172. The limiting post 165 is inserted into the sliding groove 172, thereby realizing the sliding connection between the third bracket 17 and the second bracket 16. Of course, in other embodiments, the second bracket 16 may also be provided with a vertically extending sliding groove 172, and the third bracket 17 may be provided with a limiting post 165. In addition, the number of sliding grooves 172 can be set to one, two, or more according to actual needs. For example, in this embodiment, the third bracket 17 is provided with two sliding grooves 172 spaced apart in the width direction, and the two sliding grooves 172 are parallel to each other. Correspondingly, the second bracket 16 is provided with two limiting posts 165, and the limiting posts 165 are inserted one-to-one into the sliding grooves 172. In this way, the assembly stability of the second bracket 16 and the third bracket 17 can be guaranteed, and the sliding of the third bracket 17 can also be made smoother.

[0079] Furthermore, such as Figure 5 As shown, based on the above embodiment, the humidification module further includes a humidification membrane assembly 18 and a fan 19. The humidification membrane assembly 18 is disposed in the water tank 11, and the air inlet side of the fan 19 is disposed opposite to the humidification membrane assembly 18. The humidification membrane assembly 18 is used to adsorb the disinfectant generated by electrolysis in the water tank 11, and the fan 19 is used to blow out the disinfectant evaporated by the humidification membrane assembly 18 and humidify the ambient air.

[0080] Specifically, please combine Figure 9 The water tank 11 contains a first tank for placing the electrolysis module 12 and a second tank for placing the humidification membrane assembly 18. The first and second tanks are interconnected and extend in two different directions, giving the water tank 11 a general "L" shape. The first tank also contains two support seats for supporting the water tank 15. The two support seats are spaced apart. In use, the water tank 15 is placed on the support seats with its outlet facing downwards and located between the two support seats. The solution in the water tank 15 flows into the water tank 11 to a certain depth, submerging part of the electrolysis plates of the electrolysis module 12 and the humidification membrane assembly 18. At this time, the user activates the disinfection mode. The electrolysis module 12 operates for a certain period of time to electrolyze the solution in the water tank 11 to form disinfectant. The humidifying membrane assembly 18 absorbs the disinfectant in the water tank 11. The fan 19 directs the airflow to the air outlet 22 of the air purification device 100. During the airflow, the air passes through the humidifying membrane assembly 18, carrying away the disinfectant evaporated by the humidifying membrane assembly 18 with the airflow and blowing it out of the air outlet 22 into the room, thereby disinfecting the indoor air and object surfaces. The fan 19 may specifically include a duct shell and a fan wheel installed in the duct shell. The fan wheel may include, but is not limited to, a cross-flow fan wheel or a centrifugal fan wheel.

[0081] Specifically, the humidifying membrane assembly 18 includes a rotating wheel, an adsorption membrane, and a driving component. The adsorption membrane is disposed on the rotating wheel, and the driving component is driven to rotate the rotating wheel. The rotating wheel can be rotatably mounted in the water tank 11 via a bracket. The rotating wheel includes a wheel body and multiple spokes extending circumferentially from the center of the wheel body. The rotating wheel is placed vertically and can rotate around a horizontal axis. The bottom of the rotating wheel is located inside the water tank 11, and the adsorption membrane is fixed on the rotating wheel. The adsorption membrane can be made of a mesh membrane or a porous membrane with good hygroscopic properties. Optionally, the adsorption membrane adopts a mesh structure, which facilitates the rapid and smooth passage of airflow through the adsorption membrane, and the mesh structure facilitates the rapid evaporation of liquid on the adsorption membrane, thereby improving the humidification and disinfection efficiency. Optionally, the driving component is driven to rotate around the axis of the rotating wheel. The operation of the driving component drives the rotating wheel to rotate around the axis. One rotation of the rotating wheel can completely wet the adsorption membrane, ensuring that the adsorption membrane can quickly and fully wet the disinfectant, achieving a good adsorption effect, thereby improving the humidification and disinfection efficiency and increasing user satisfaction. For example, the driving component can be a drive motor, which is directly connected to one end of the rotating shaft of the wheel. The overall structure is simple and occupies little space. Of course, in other embodiments, power can also be transmitted between the driving component and the rotating wheel through a transmission assembly (such as a gear assembly or a timing belt).

[0082] During disinfection, the bottom of the adsorption membrane is immersed in the disinfectant solution in the water tank 11. The disinfectant solution spreads upwards along the adsorption membrane. Simultaneously, the drive mechanism rotates the rotating wheel, which in turn rotates the adsorption membrane, ensuring that different parts of the membrane are fully immersed and adsorb the disinfectant solution. The rotation of the wheel ensures rapid and uniform immersion, increasing the adsorption capacity and uniformity, thus improving adsorption efficiency. When airflow passes through the adsorption membrane, the rotating wheel accelerates the evaporation of the disinfectant solution. The airflow blows the evaporated disinfectant solution onto the room and object surfaces, humidifying and disinfecting the indoor environment and improving environmental comfort. Furthermore, after the humidification and disinfection operation is complete, the drive mechanism can continue to rotate the wheel for a certain period, allowing the adsorption membrane to continue adsorbing any remaining disinfectant solution in the water tank 11. This transfers and collects salts from the water tank 11 onto the adsorption membrane, further preventing salt accumulation and bacterial growth in the water tank 11, reducing the frequency of cleaning and improving user satisfaction. Because the adsorption membrane has a large adsorption area, it can accumulate a significant amount of salt, eliminating the need for frequent membrane replacement. Replacement is only required when the salt concentration on the membrane reaches a certain level. For example, users can replace the adsorption membrane every three to six months, significantly reducing the frequency of operation and further improving user satisfaction.

[0083] Please refer to Figure 13 and Figure 14In one embodiment, the water tank 11 includes a first tank body 115 and a second tank body 116. The first tank body 115 is provided with an electrolysis chamber 1151 and a waste liquid extraction chamber 1152. The second tank body 116 is provided with an adsorption chamber 1161. The electrolysis chamber 1151 and the waste liquid extraction chamber 1152 are located on opposite sides of the adsorption chamber 1161. The electrolysis chamber 1151 and the adsorption chamber 1161 are connected through a first liquid passage 117. The adsorption chamber 1161 and the waste liquid extraction chamber 1152 are connected through a second liquid passage 118. The electrolysis module 12 is disposed in the electrolysis chamber 1151. The liquid inlet end of the conveying component 14 is disposed in the waste liquid extraction chamber 1152. The humidifying membrane component 18 is disposed in the adsorption chamber 1161.

[0084] Specifically, the extension directions of the first groove 115 and the second groove 116 intersect, and the extension directions of the first groove 115 and the second groove 116 may intersect perpendicularly or obliquely. For example, in this embodiment, the extension directions of the first groove 115 and the second groove 116 are substantially perpendicular. The first tank 115 is provided with a water tank placement area 1153 for placing the water supply tank 15 and a waste liquid tank placement area 1154 for placing the waste liquid tank 13. The water tank placement area 1153 and the waste liquid tank placement area 1154 are arranged side by side along the extension direction of the first tank 115. The water tank placement area 1153 is provided with a receiving cavity 1155 for accommodating the outlet of the water supply tank 15. The electrolysis cavity 1151 is located on the side of the water tank placement area 1153 near the second tank 116. The waste liquid extraction cavity 1152 is located on the side of the waste liquid tank placement area 1154 near the second tank 116. The electrolysis cavity 1151 and the waste liquid extraction cavity 1152 are separated by the second tank 116. The water tank 11 has a compact overall structure, reasonable layout, and occupies little space. During disinfection, a solution is injected into the electrolysis chamber 1151 through the water tank 15. The electrolysis module 12 electrolyzes the solution in the electrolysis chamber 1151 into a disinfectant. The disinfectant enters the adsorption chamber 1161 through the first liquid passage 117 and is humidified by the humidification membrane assembly 18. During the waste liquid extraction process, the residual solution in the electrolysis chamber 1151 enters the waste liquid extraction chamber 1152 sequentially through the first liquid passage 117, the adsorption chamber 1161, and the second liquid passage 118 (e.g., ...). Figure 14 (As indicated by the middle arrow), and then transported to the waste liquid tank 13 via the conveying assembly 14.

[0085] Further, please refer to Figure 1 and Figure 2Based on the above embodiments, the air purification device 100 further includes a housing 20, which has an air inlet 21, an air outlet 22, and an exhaust outlet 23. The water tank 11, the waste liquid tank 13, and the water tank 15 are all located inside the housing 20 and can be removed from the exhaust outlet 23. Specifically, the housing 20 constitutes the main body shape of the air purification device 100, and the housing 20 can be set as a square, cylindrical, or other irregular shape according to actual needs. The housing 20 can be a metal shell made of sheet metal or a plastic shell made of acrylic sheet. The housing 20 has an air inlet 21, an air outlet 22, and an exhaust outlet 23. The number of air inlets 21 and air outlets 22 can be set to one, two, or more. For example, in this embodiment, the housing 20 is generally square in shape. The housing 20 includes a panel and two side plates disposed on the left and right sides of the panel. The panel of the housing 20 is provided with an air outlet 22, and the left and right side plates of the housing 20 are respectively provided with air inlets 21. Grilles or filters can also be provided at the air inlets 21 and air outlets 22 to filter the incoming and outgoing air. The water tank 11 and the waste liquid tank 13 are located inside the housing 20 and can be pulled out from the extraction port 23, which facilitates the user to clean the water tank 11 and also facilitates the user to remove the waste liquid tank 13 to empty the waste liquid. In addition, the water tank 15 can also be removed from the extraction port 23 so that the user can add water or salt solution to the water tank 15.
