[0056] Reference below Figure 1-Figure 18 A water supply module 100 of an air purification device 1000 according to an embodiment of the present invention is described.

[0057] A water supply module 100 of an air purification device 1000 according to an embodiment of the present invention comprises: a body 1, a drawer 2, an electrolysis unit 3 and a drive assembly 4. The body 1 defines a receiving chamber 11, and one side of the receiving chamber 11 has a pull-out opening 12. The drawer 2 is provided in the receiving chamber 11 so as to be pullable from the pull-out opening 12, and a working groove 21 is provided on the drawer 2.

[0058] like Fig.11 and Fig.15 The schematic diagram shown is that the drawer 2 is pulled out from the body 1, and the body 1 is provided with a receiving cavity 11 inside, and the structure can be accommodated inside the receiving cavity 11. The receiving cavity 11 is provided with a drawing opening 12, that is, an opening for the drawer 2 to be pulled out and pushed in.

[0059] In other words, the drawer 2 can be pulled out from the drawer opening 12 of the body 1, or pushed into the accommodating cavity 11 inside the body 1 from the drawer opening 12 to carry objects. Fig.11 As shown, a working tank 21 is provided on the drawer 2, and the working tank 21 can store objects, thereby realizing the storage function of the drawer 2. When in use, salt water can be directly placed in the working tank 21, or the working tank 21 can only contain clean water and the salt-containing object can be placed in the working tank 21 before each disinfection.

[0060] like Figure 2 , Figure 3 , Figure 5 , Figure 6 , Fig. 9 , Fig.15 and Fig.16 As shown, the electrolysis unit 3 is arranged on the body 1 to generate disinfectant water when electrolyzing the salt water. The salt water can be electrolyzed by the electrolysis unit 3, so that the salt water can generate disinfectant water with disinfectant effect by electrolysis. The electrolysis of the salt water can make the substances in the salt water form substances containing hypochlorous acid, so that the salt water can form water with disinfectant effect after electrolysis, that is, disinfectant water.

[0061] like Figure 2and Figure 3 As shown, the driving assembly 4 is arranged on the main body 1, and the driving assembly 4 is connected to the electrolytic unit 3. The driving assembly 4 drives the electrolytic unit 3 to move between the working position and the avoidance position. When in the working position, at least part of the electrolytic unit 3 is located in the working groove 21. When in the avoidance position, the electrolytic unit 3 is separated from the drawer 2, so that the drawer 2 moves outward over the electrolytic unit 3.

[0062] Specifically, the main body 1 is provided with an electrolysis unit 3 and a driving assembly 4, and the driving assembly 4 provides a driving force to the electrolysis unit 3, so that the electrolysis unit 3 can move between the working position and the avoidance position. The electrolysis unit 3 can move linearly or rotationally. The position movement of the electrolysis unit 3 can enable the electrolysis unit 3 to electrolyze the salt water to generate disinfectant water at the working position. Accordingly, when the electrolysis unit 3 is in the avoidance position, the electrolysis unit 3 avoids the drawer 2 to prevent the drawer 2 from interfering with the electrolysis unit 3 during the pulling process.

[0063] like Figure 2 , Figure 3 and Figure 6 As shown, the drawer 2 is located in the receiving chamber 11 inside the body 1, and the electrolysis unit 3 is located in the working position. The working tank 21 can store salt water, and when the electrolysis unit 3 is in the working position, it is at least partially immersed in the salt water, and can electrolyze the salt water in the working tank 21.

[0064] Combination Fig.14 and Fig.16 It is known that in Fig.15 FIG. 1 is a schematic diagram showing a structure in which the drawer 2 is pulled out from the body 1. Fig.14 , which is a diagram of the internal structure of the drawer 2 of the water supply module 100. When the drawer 2 needs to be pulled out from the inside of the body 1, the driving assembly 4 drives the electrolytic unit 3 to transfer, so that the electrolytic unit 3 is completely separated from the drawer 2. When the drawer 2 moves outward, the drawer opening 12 can be only partially pulled out, or the drawer opening 12 can be fully pulled out.

[0065] According to the water supply module 100 of the air purification device 1000 of the embodiment of the present invention, by arranging the electrolysis unit 3 and the driving component 4 on the main body 1, the position of the electrolysis unit 3 can be adjusted by the driving component 4, that is, the position adjustment of the electrolysis unit 3 between the working position and the avoidance position can be achieved, so that the electrolysis unit 3 in the working position can be at least partially in the working tank 21, and the salt water can be electrolyzed to generate disinfectant water, and the electrolysis unit 3 in the avoidance position is completely separated from the drawer 2, preventing the drawer 2 from interfering with the electrolysis unit 3 when being pulled out, so that the drawer 2 is very convenient to clean.

[0066] Furthermore, the driving assembly 4 includes a first driving motor 41 disposed on the inner wall of the body 1, and the motor shaft of the first driving motor 41 is connected to the electrolysis unit 3. By connecting the motor shaft of the driving assembly 4 to the electrolysis unit 3, when the motor shaft rotates, the driving assembly 4 is driven to rotate, so that the electrolysis unit 3 can be switched between the working position and the avoidance position.

[0067] Specifically, the first drive motor 41 is a bidirectional rotating motor, that is, the first drive motor 41 can drive the electrolysis unit 3 to rotate forward and reverse, so as to drive the electrolysis unit 3 to switch between the working position and the avoidance position. In some solutions, the electrolysis unit 3 has no obstacles within the 360-degree rotation range, and in this case, the first drive motor 41 can also be a unidirectional rotating motor.

[0068] The operation of the first drive motor 41 can be controlled by directly setting the switch of the first drive motor 41. For example, a cleaning control component and a disinfection control component are provided on the body 1. When the cleaning control component is triggered, the first drive motor 41 drives the electrolysis unit 3 to convert toward the avoidance position. When the disinfection control component is triggered, the first drive motor 41 drives the electrolysis unit 3 to convert toward the working position. The operation of the first drive motor 41 can also be automatically controlled by the internal program of the air purification device 1000. For example, when the air purification device 1000 is turned on, the first drive motor 41 automatically converts the electrolysis unit 3 toward the working position; when the air purification device 1000 is turned off, the first drive motor 41 automatically converts the electrolysis unit 3 toward the avoidance position. In other schemes, the operation of the first drive motor 41 can be controlled by remote control or wirelessly, which is not limited here.

[0069] In an optional embodiment of the present invention, the connection between the electrolytic unit 3 and the motor shaft can be that the motor shaft is connected to the electrolytic unit 3 at an eccentric position, so that when the motor shaft rotates, the electrolytic unit 3 can rotate eccentrically, thereby effectively making the part of the electrolytic unit 3 at least partially located in the working tank 21 separate from the working tank 21.

[0070] Optionally, the rotation range of the first driving motor 41 is 90 degrees, and the rise and fall of the electrolysis unit 3 can be controlled within a smaller rotation range.

[0071] like Fig.11 and Fig.12 As shown, the drawer 2 is provided with a confluence groove 22 having a drain port and a first connecting port 221 . The confluence groove 22 is connected to the working groove 21 via the first connecting port 221 . The water supply module 100 also includes a first switch assembly 10 for controlling the on and off of the first connecting port 221 .

[0072] Specifically, Fig.11 and Fig.12As shown, a confluence groove 22 is provided on the drawer 2, and the confluence groove 22 has a drain port (not shown) and a first connecting port 221. After being connected with the working groove 21 through the first connecting port 221, the disinfectant water generated after electrolysis in the working groove 21 can flow into the confluence groove 22, and the disinfectant water entering the confluence groove 22 is discharged through the drain port.

[0073] A working tank 21 and a confluence tank 22 are provided on the drawer 2, wherein the working tank 21 is an electrolysis area, and the confluence tank 22 is a collection area for external water supply. Separating the electrolysis area from the external water supply area helps to flexibly set more usage modes according to needs. For example, clean water can be directly collected at the confluence tank 22, and the confluence tank 22 can avoid the working tank 21 when supplying clean water. For another example, the working tank 21 can provide an independent working space for the electrolysis unit 3, and the electrolysis unit 3 can be immersed in water and work continuously for a period of time to increase the content of disinfection components in the water. When the disinfection water reaches the required amount, the disinfection water is supplied to the confluence tank 22. For another example, when the water supply module 100 is turned off, the confluence tank 22 does not need to be supplied with water. At this time, the working tank 21 and the confluence tank 22 are disconnected, and water can exist in the working tank 21.

[0074] like Fig.12 As shown, a first switch assembly 10 is provided at the connection between the first communication port 221 and the working tank 21, and the first switch assembly 10 can connect or disconnect the connection between the first communication port 221 and the working tank 21. In this way, the action of the first switch assembly 10 can control the opening size of the first communication port 221, thereby controlling the water volume and water supply speed from the working tank 21 to the confluence tank 22.

[0075] Further, such as Figure 3 and Fig.13 As shown, the first switch assembly 10 includes: a first switch motor 101 and a first rotating door 102 . The first rotating door 102 is rotatably disposed at the first communication port 221 , and the rotating shaft of the first rotating door 102 is connected to the first switch motor 101 .

[0076] Specifically, the first switch motor 101 can rotate the first rotating door 102 so that the angle between the first rotating door 102 and the first communication port 221 forms a gap, so that the water in the working tank 21 can flow into the confluence tank 22 through the gap. Accordingly, when the first rotating door 102 is tightly fitted with the edge of the first communication port 221, the first communication port 221 can be closed, and the water in the working tank 21 cannot flow into the confluence tank 22.

[0077] By controlling the rotation angle of the first rotating door 102, the rate at which the brine in the working tank 21 flows into the confluence tank 22 can be controlled, thereby achieving the function of flow rate regulation.

[0078] Specifically, the first communication port 221 is provided on the first partition rib 241 between the working slot 21 and the confluence slot 22, and the first communication port 221 completely penetrates the first partition rib 241 upward. The rotation axis of the first rotating door 102 is provided in the first communication port 221, and the rotation axis of the first rotating door 102 is vertically arranged. The opposite two sides of the first rotating door 102 in the horizontal direction are respectively located at the opposite two sides of the first partition rib 241, so that when the first communication port 221 is closed, the opposite two sides of the first rotating door 102 are respectively attached to the opposite two sides of the first partition rib 241 after rotation.

[0079] More specifically, a sealing strip is provided on the first rotating door 102, and the sealing strip is a rubber strip, which not only has a good sealing effect, but also has excellent corrosion resistance.

[0080] Optionally, the first switch motor 101 is located above the first communication port 221 , so that the first switch motor 101 can be protected.

[0081] Further, such as Figure 3 and Fig.12 As shown, the first switch motor 101 is a magnetic levitation motor, the fixed part of the first switch motor 101 is installed on the body 1, the rotating part of the first switch motor 101 is connected to the first rotating door 102, and the first rotating door 102 is rotatably arranged on the drawer 2. Of course, the structure and working principle of the magnetic levitation motor are prior art and will not be described here.

[0082] Specifically, the fixed part and the rotating part of the first switch motor 101 can be combined and separated, the fixed part is equivalent to the stator of a conventional motor, and the rotating part is equivalent to the rotor of a conventional motor. When the drawer 2 is closed, the drawer 2 drives the rotating part to match the fixed part. At this time, the fixed part can drive the rotating part to rotate when powered, so that the rotating part can drive the first rotating door 102 to rotate. When the drawer 2 is opened, the rotating part is separated from the fixed part. At this time, the rotating part and the first rotating door 102 cannot be driven, and it is very safe to clean at this time.

[0083] Under this design, since the fixed part and the rotating part of the first switch motor 101 can be combined and disengaged, when the drawer 2 is pulled out to the pull-out opening 12, it will not be affected by the interference of the fixed part of the first switch motor 101, and the drawer 2 can even be completely removed from the main body 1.

[0084] Of course, in other solutions, the first switch motor 101 can also be set as a conventional motor, that is, the stator and rotor of the first switch motor 101 are inseparable. In this case, the first switch motor 101 can be installed on the drawer 2, and the connection line of the first switch motor 101 is set to have a certain redundant length.

[0085] In some specific embodiments, Fig.11 and Fig.13 As shown, a water storage tank 23 is provided on the drawer 2, and the water storage tank 23 is connected to the working tank 21 through a second communication port 231. The water storage tank 23 can store water, so that the water supply module 100 does not need to be frequently added with water when in use.

[0086] like Figure 3 and Fig.13 As shown, the water supply module 100 further includes a second switch assembly 20 for controlling the on and off of the second communication port 231, and the second switch assembly 20 includes: a second switch motor 201 and a second rotating door 202, the second rotating door 202 is rotatably arranged at the second communication port 231, and the rotating shaft of the second rotating door 202 is connected to the second switch motor 201. In this way, the action of the second switch motor 201 and the rotation angle of the second rotating door 202 can control the opening size of the second communication port 231, thereby controlling the amount of water flowing from the water storage tank 23 to the working tank 21 and the water supply speed.

[0087] Specifically, the second communication port 231 is provided on the second partition rib 242 between the working tank 21 and the water storage tank 23, and the second communication port 231 completely penetrates the second partition rib 242 upward. The rotation axis of the second rotating door 202 is provided in the second communication port 231, and the rotation axis of the second rotating door 202 is vertically arranged. The opposite two sides of the second rotating door 202 in the horizontal direction are respectively located at the opposite two sides of the second partition rib 242, so that when the second communication port 231 is closed, the opposite two sides of the second rotating door 202 are respectively attached to the opposite two sides of the second partition rib 242 after rotation.

[0088] More specifically, a sealing strip is provided on the second rotating door 202, and the sealing strip is a rubber strip, which not only has a good sealing effect, but also has excellent corrosion resistance.

[0089] Optionally, the second switch motor 201 is located above the second communication port 231 , so that the second switch motor 201 can be protected.

[0090] Further, such as Figure 3 and Fig.12 As shown, the second switch motor 201 is a magnetic suspension motor, the fixed part of the second switch motor 201 is installed on the body 1, the rotating part of the second switch motor 201 is connected to the second rotating door 202, and the second rotating door 202 is rotatably arranged on the drawer 2.

[0091] Specifically, the fixed part and the rotating part of the second switch motor 201 can be combined and disengaged. When the drawer 2 is closed, the drawer 2 drives the rotating part to match the fixed part. At this time, the fixed part can drive the rotating part to rotate when powered, so that the rotating part can drive the second rotating door 202 to rotate. When the drawer 2 is opened, the rotating part is separated from the fixed part. At this time, the rotating part and the second rotating door 202 cannot be driven, and it is very safe to clean at this time.

[0092] Of course, in other solutions, the second switch motor 201 can also be set as a conventional motor, that is, the stator and rotor of the second switch motor 201 are inseparable. In this case, the second switch motor 201 can be installed on the drawer 2, and the connecting wire of the second switch motor 201 is set to have a certain redundant length.

[0093] like Figure 2 , Figure 3 and Fig.11 As shown, the water supply module 100 of the air purification device 1000 also includes a water tank 232 arranged in the water storage tank 23. By arranging the water tank 232 in the water storage tank 23, the water storage capacity can be increased. The water tank 232 can store clean water or salt water. When the amount of salt water inside the working tank 21 is insufficient, the salt water in the water tank 232 can be used to supply water to the electrolysis unit 3 in the working tank 21, which can ensure the long-term stable operation of the electrolysis unit 3, thereby also improving the overall working time of the air purification device 1000. In some schemes, no salt is added to the working tank 21, and the water tank 232 only supplies clean water to the working tank 21. At this time, the electrolysis unit 3 does not need to work, and the working tank 21 supplies clean water to the confluence tank 22.

[0094] In some embodiments, Fig.11 As shown, a first partition rib 241 and a second partition rib 242 are provided in the drawer 2, so that the cavity of the drawer 2 is divided into a working groove 21, a confluence groove 22 and a water storage groove 23. Specifically, the second partition rib 241 is substantially parallel to the drawer opening 12, and the length of the second partition rib 241 is substantially equal to the length of the drawer opening 12. Optionally, the first partition rib 241 is vertically connected to the second partition rib 242.

[0095] Specifically, the first communication port 221 is disposed on the first partition rib 241, and the second communication port 241 is disposed on the second partition rib 242. When the second communication port 241 is opened, the water storage tank 23 supplies water to the working tank 21; when the second communication port 221 is opened, the working tank 21 supplies water to the confluence tank 22.

[0096] In some solutions, the water storage tank 23 stores clean water, and a third connecting port (not shown) may be provided on the second partition rib 242, and the third connecting port is used to connect the water storage tank 23 and the confluence tank 22. The water supply module 100 further includes a third switch assembly for controlling the on-off of the third connecting port, so that when clean water is required, the third connecting port is opened. When disinfectant water is required, the first connecting port 221 is opened.

[0097] Furthermore, the main body 1 is provided with a crossbeam 13 above the drawer 2, and the crossbeam 13 can be used to fix each switch assembly. Figure 3In the embodiment, the fixing parts of the first switch motor 101 and the second switch motor 201 are installed on the crossbeam 13. Optionally, the crossbeam 13 is consistent with the shape of the partition ribs on the drawer 2, such as Figure 3 The center cross member 13 is formed in a T-shape.

[0098] In some specific embodiments, Figure 3 As shown, the water supply module 100 of the air purification device 1000 further includes: a float 6 and a magnetic induction switch 5 for sensing the water level in the working tank 21. Figure 6 and Figure 7 As shown, the float 6 is arranged in the working tank 21, and the float 6 can float, that is, when there is water in the working tank 21, the float 6 can float by buoyancy, that is, the float 6 can be at the liquid surface to display the liquid surface height. The magnetic induction switch 5 is arranged on the body 1 and corresponds to the float 6. Thus, through the cooperation between the float 6 and the magnetic induction switch 5, the magnetic induction switch 5 can sense the position of the float 6, so that the air purification device 1000 can effectively obtain the amount of water in the working tank 21, which is convenient for the operation of the air purification device 1000 and improves the intelligence of the air purification device 1000.

[0099] For example, the magnetic induction switch 5 is used to sense the lowest water level in the working tank 21. When the float 6 floats at the lowest water level, the first connecting port 221 is closed, the second connecting port 231 is opened, and the water storage tank 23 supplies water to the working tank 21 to ensure that the electrodes of the electrolytic unit 3 are immersed in water.

[0100] Of course, in order to realize a more intelligent operation of the water supply module 100, the water supply module 100 may also be provided with other water level detection components, for example, the specific water level in the working tank 21 may be detected to prevent the electrolysis unit 3 from being short-circuited due to excessive water in the working tank 21. The structures of these detection components may adopt water level detectors known in the prior art, which are not limited here.

[0101] In some embodiments, the water supply module 100 further includes a water pump (not shown), which is used to pump the water in the drawer out. Specifically, the water pump can be located in the confluence tank 22, and directly pump the required water out of the confluence tank 22. In some embodiments, the water pump directly pumps water from the working tank 21.

[0102] Specifically, the water pump can also be set to a rotatable structure, for example, the driving assembly 4 also includes a second driving motor (not shown) arranged on the inner wall of the body 1, and the motor shaft of the second driving motor is connected to the water pump to drive at least part of the water pump to extend into or withdraw from the drawer 2. That is, the water pump can also have a working position and an avoidance position. When it is in the working position, the water inlet of the water pump is immersed in the water in the drawer 2. When it is in the avoidance position, the water pump is completely separated from the drawer 2, and the drawer 2 can pass over the water pump when moving outward.

[0103] It should be added here that the clean water mentioned above can be purified water or tap water.

[0104] Reference below Figure 1-Figure 18 An air purification device 1000 according to an embodiment of the present invention is described.

[0105] An air purification device 1000 according to an embodiment of the present invention includes: a body 200, a humidification module 300, a water supply module 100 and a fan assembly 400. Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.16 As shown, the humidification module 300 is arranged on the machine body 200, and the electrolyzed disinfectant water can flow to the humidification module 300 through the humidification module 300 to be supplied for use in the subsequent disinfection steps. The water supply module 100 is arranged on the machine body 200, and the water supply module 100 is connected to the humidification module 300 to supply disinfectant water. That is, the salt water electrolyzed by the electrolysis unit 3, that is, the disinfectant water, is supplied to the humidification module 300 through the water supply module 100, so that the disinfectant water can act on the humidification module 300, which is convenient for subsequent use.

[0106] Specifically, the water supply module 100 may be disposed on the top of the machine body 200, so that the water in the water supply module 100 flows downward to the humidification module 300 by gravity, thereby reducing energy consumption.

[0107] Specifically, Fig.18 As shown, it is another embodiment of the present invention, the water supply module 100 can be arranged at the bottom of the body 200, and the water in the water supply module 100 can be pumped to the top of the humidification module 300 by a water pump, and a drawer can be used to collect water under the humidification module. Optionally, a water distribution tank is provided on the top of the humidification module 300, and the water supply module 100 pumps the water in the drawer 2 to the water distribution tank through a water pump.

[0108] The fan assembly 400 is used to drive air to flow through the humidification module 300, that is, the fan assembly 400 can be used to suck the external air, so that the external air flows through the humidification module 300 of the air purification device 1000, and is blown into the air from one side of the fan on the air purification device 1000, thereby blowing the disinfectant water on the humidification module 300 into the air through wind force, thereby achieving the disinfection of the external air. Thereby, the disinfection effect of the air purification device 1000 is achieved.

[0109] According to the air purification device 1000 of the embodiment of the present invention, the salt water electrolyzed by the electrolysis unit 3, that is, the disinfectant water is supplied to the humidification module 300 through the water supply module 100, and further cooperates with the fan assembly 400. When the external air is sucked through the humidification module 300 by the action of wind, the disinfectant water on the humidification module 300 is simultaneously blown into the external air, thereby achieving the disinfection effect on the external air. Therefore, the disinfection and sterilization of the external air can be achieved, and the overall structure is compact.

[0110] Specifically, the air purification device 1000 further includes: an environment detection component (not shown), which is used to detect the temperature and humidity of the environment in which the air purification device 1000 is located, and the water supply module 100 is electrically connected to the environment detection component and the fan assembly 400. In this way, the intelligent control of the water supply module 100 can be achieved by using environmental parameters and operating parameters of the fan assembly 400.

[0111] The opening and closing degree of the first switch assembly 10 and the second switch assembly 20 in the embodiment of the present invention can have the effect of controlling the flow rate of the salt water. Fig.17 As shown, the control of the opening and closing angles of the first rotating door 102 of the first switch assembly 10 and the opening and closing angles of the second rotating door 202 of the second switch assembly 20 needs to be coordinated with the rotation speed of the fan assembly 400, the temperature and humidity of the external environment, the magnetic induction switch 5 for sensing the water level, and the electrolysis time of the electrolysis unit 3 for the brine.

[0112] In addition, sealing strips can be provided on both sides of the first revolving door 102 and the second revolving door 202, thereby further improving the sealing performance when the first revolving door 102 closes the first connecting port 221 and the working groove 21, and further improving the sealing performance when the second revolving door 202 closes the second connecting port 231 and the working groove 21.

[0113] The operation process of the air purification device 1000 according to the embodiment of the present invention is described in detail below in conjunction with the accompanying drawings: by pre-storing salt water in the water tank 232, the salt water in the water tank 232 can provide a continuous water supply to the electrolysis unit 3, thereby ensuring that the electrolysis unit 3 can work continuously for a long time.

[0114] After the electrolysis unit 3 electrolyzes the brine in the working tank 21, the electrolyzed brine generates disinfectant water containing hypochlorous acid. The disinfectant water flows from the working tank 21 through the confluence tank 22 and is transported to the humidification module 300 through the water supply module 100. At the same time, the disinfectant water can also automatically flow to the humidification module 300 through the action of gravity.

[0115] At this time, the fan assembly 400 is running, and the fan assembly 400 draws the external air, so that after the external air passes through the humidification module 300, the disinfectant water on the humidification module 300 is brought into the air by the action of wind, thereby achieving the disinfection effect on the air.

[0116] The brine in the water tank 232 flows into the working tank 21, that is, flows into the working tank 21 through the water storage tank 23, and needs to pass through the second connecting port 231 and the second rotating door 202. The second rotating door 202 is opened and rotated by the control of the second switch motor 201, so that the second rotating door 202 forms a gap with a certain angle at the first connecting port 221, thereby realizing the circulation of brine.

[0117] Correspondingly, the electrolyzed brine, i.e., the disinfectant water, needs to pass through the first rotating door 102 and the first connecting port 221 to flow into the confluence trough 22. The first rotating door 102 is rotated by the control of the first switch motor 101, thereby forming a gap at the first connecting port 221, so that the disinfectant water can flow from the working trough 21 into the confluence trough 22.

[0118] The first switch motor 101 can drive the first rotating door 102 to open and close by rotating, and the rotation angle of the first rotating door 102 can be adjusted, thereby controlling the speed and flow rate of the brine flowing from the working tank 21 to the confluence tank 22 .

[0119] Correspondingly, the second switch motor 201 can drive the second rotating door 202 to open and close by rotating, and the rotation angle of the second rotating door 202 can be adjusted, thereby controlling the speed and flow rate of the brine flowing from the water storage tank 23 to the working tank 21.

[0120] When the drawer 2 needs to be cleaned, the electrolytic unit 3 connected to the motor shaft of the first drive motor 41 can be rotated by rotating the first drive motor 41, and moved from the working position to the avoidance position, that is, at least part of the electrolytic unit 3 located in the working tank 21 is also separated from the working tank 21, so that when the drawer 2 is pulled out of the main body 1, there will be no interference with the electrolytic unit 3.

[0121] In the air purification device 1000 of the embodiment of the present invention, the water tank 232 and the drawer 2 are arranged on the top structure of the body 200, so as to solve the problem of interference between the drawer 2 and the electrolytic unit 3 during the process of removing the drawer 2.

[0122] At the same time, the brine in the water tank 232 needs to be drained after the electrolysis of the electrolysis unit 3 is completed, so as to prevent the salt concentration in the electrolysis unit 3 from being diluted by the newly injected brine. In addition, the brine in the electrolysis unit 3 needs to be electrolyzed before the disinfectant water is released. The released disinfectant water enters the humidification module 300, and the wind generated by the fan assembly 400400 passes through the surface of the humidification module 300 and releases the disinfectant water into the air, and the disinfectant water in the air can have a disinfecting and sterilizing effect.

[0123] In order to prevent excess water from leaking out after the disinfectant water passes through the two humidification modules 300, it is necessary to control the opening angle and time of the first rotating door 102 of the first switch module of the electrolysis unit 3 so that the disinfectant water can evaporate into the air after passing through the humidification module 300, wherein the humidification module 300 can be a hydrophobic filter layer.
