[0054] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0055] The air treatment device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0056] Reference Figure 1-Figure 4 The air treatment device 100 according to the embodiment of the present invention comprises a housing 10 and an air treatment unit 20. The housing 10 forms a first air inlet 13, a first air outlet 14 and an operation port 17. The air treatment unit 20 is arranged in the housing 10 and comprises a humidification module 21 and an electric control component. A first fan component 22 may be arranged in the housing 10. The first fan component 22 may drive air to enter the housing 10 through the first air inlet 13, and after humidification treatment by the air treatment unit 20, the air flows out from the first air outlet 14 to realize the humidification function of the air treatment device 100. The operation port 17 is used for the water injection operation of the humidification module 21. The humidification module 21 may be directly injected with water at the position of the operation port 17. The operation is simple and convenient to use.

[0057] The first air inlet 13 may be connected to the indoor environment, or the first air inlet 13 may be connected to the outdoor environment.

[0058] The humidification module 21 includes a water tank 30, a water trough component 40, a humidification component 60 and a water injection component 50. The water trough component 40 has a water trough 41. The water tank 30 has a water supply channel 31 for supplying water to the water trough 41. A water supply valve 32 is provided in the water supply channel 31. The electronic control component is electrically connected to the water supply valve 32 to control the water supply valve 32 to connect or cut off the water supply channel 31. The humidification component 60 is provided in the water trough 41. The water tank 30 has a water replenishment hole 33. The water injection component 50 has a water injection chamber 51 and a water injection inlet 52 and a water injection outlet 53 connected to the water injection chamber 51. The humidifying component 60 in the water tank 41 can realize the humidification function of the air. The water tank 30 is used to supply water to the water tank 41 to ensure that there is sufficient water in the water tank 41 for humidifying the humidifying component 60. When the amount of water in the water tank 30 is insufficient to supply water to the water tank 41, that is, the water tank 30 needs to be filled with water, the water filling operation of the water tank 30 can be realized through the water filling component 50 at the position of the operating port 17. Therefore, there is no need to disassemble, transport and assemble the water tank 30, and the operation is simple and easy to use.

[0059] Optionally, the humidifying component 60 may include a wet film support 61 and a wet film 62 arranged on the wet film support 61 , and the lower end of the humidifying component 60 is arranged in the water tank 41 to ensure that the lower part of the wet film 62 is immersed in the water of the water tank 41 to achieve the humidification effect of the humidifying component 60 .

[0060] Optionally, the humidifying component 60 may include an atomizer, which is disposed in the water tank 41 , and the water in the water tank 41 is atomized by the atomizer to achieve the humidifying effect of the humidifying component 60 .

[0061] The electric control component is electrically connected to the water supply valve 32 to control the water supply valve 32 to conduct or cut off the water supply channel 31. When the water supply valve 32 conducts the water supply channel 31, the water in the water tank 30 can flow into the water tank 30 through the water supply channel 31. When the water supply valve 32 cuts off the water supply channel 31, the water in the water tank 30 cannot flow into the water tank 30. By setting the water supply valve 32 as an electric control valve and electrically connecting the electric control component to the water supply valve 32, the working state of the water supply valve 32 can be conveniently controlled, so that the water supply valve 32 can be conveniently controlled to conduct or cut off the water supply channel 31, and the water tank 30 can be conveniently controlled to supply water to the water tank 41 or stop supplying water.

[0062] For example, when it is necessary to humidify the indoor air, the electronic control component controls the water supply valve 32 to open the water supply channel 31, and the water tank 30 supplies water to the water tank 41 through the water supply channel 31; when it is not necessary to humidify the indoor air, the electronic control component controls the water supply valve 32 to cut off the water supply channel 31, and the water tank 30 stops supplying water to the water tank 41.

[0063] The water injection component 50 has a water injection position. In the water injection position, the water injection outlet 53 is connected to the water replenishment hole 33 and at least part of the water injection inlet 52 is exposed to the outside through the operation port 17. Through this arrangement, the water injection operation can be realized from the outside through the operation port 17, making the operation more convenient. When the water injection component 50 is in the water injection position, when the water tank 30 is injected with water, the water injection operation can be performed through the water injection inlet 52 exposed to the outside. The water injected by the water injection inlet 52 flows into the water injection cavity 51, and then flows into the water tank 30 through the water injection outlet 53 and the water replenishment hole 33, thereby realizing the water injection operation into the water tank 30. At this time, the electric control component controls the water supply valve 32, so that the water in the water tank 30 cannot flow into the water tank 41, thereby preventing the water in the water tank 41 from overflowing due to excessive water.

[0064] For example, when the water filling component 50 is in the water filling position, the electronic control component controls the water supply valve 32 to cut off the water supply channel 31, so that the water in the water tank 30 cannot flow into the water tank 41 through the water supply channel 31, thereby preventing the water in the water tank 41 from overflowing due to excessive water.

[0065] When the water injection component 50 is in the water injection position, at least part of the water injection inlet 52 is exposed to the outside through the operating port 17, that is, part of the structure of the water injection inlet 52 can be exposed to the outside through the operating port 17, or the entire water injection inlet 52 can be exposed to the outside through the operating port 17, so as to facilitate the water injection operation.

[0066] Optionally, when the water filling component 50 is in the water filling position and the water tank 30 is filled with water through the water filling inlet 52, the water level in the water tank 30 can be observed through the water filling inlet 52. When the amount of water in the water tank 30 is sufficient, the water filling operation is stopped.

[0067] Optionally, a water level gauge may be provided in the water tank 30, and the humidification module 21 may include an alarm. When the water level gauge detects that the liquid level in the water tank 30 reaches a set height, the alarm may sound an alarm to remind that the water injection operation may be stopped. When the water injection component 50 is in the water injection position, during the water injection operation of the water tank 30 through the water injection inlet 52, when the alarm sounds an alarm, the water injection operation may be stopped.

[0068] According to the air treatment device 100 of the embodiment of the present invention, when the water tank 30 of the air treatment device 100 is filled with water, water can be directly filled into the water tank 30 through the water filling component 50 at the position of the operation port 17, without the need to disassemble, carry and assemble the water tank 30, and the operation is simple and convenient. In addition, by controlling the water supply valve 32 through the electronic control component, the water tank 30 can be conveniently controlled to supply water to the water tank 41 or stop supplying water.

[0069] Reference Figure 3According to some embodiments of the present invention, at the water filling position, at least a portion of the water filling inlet 52 extends out of the housing 10 through the operation port 17. With this arrangement, when performing the water filling operation, there is enough space to fill water into the water filling inlet 52, and at the same time, the water filling operation can be performed from the outside of the housing 10 through the operation port 17, which is simple to operate and convenient to use.

[0070] At least part of the water injection inlet 52 extends out of the casing 10 through the operating port 17. Either a partial structure of the water injection inlet 52 extends out of the casing 10 through the operating port 17, or the entire water injection inlet 52 extends out of the casing 10 through the operating port 17 to facilitate the water injection operation.

[0071] Optionally, when the water injection component 50 is in the water injection position, the water injection inlet 52 is oriented upward and extends downwardly in a direction away from the housing 10. With this arrangement, the water injection inlet 52 is oriented upward, which can facilitate water injection at the water injection inlet 52, and the water injection inlet 52 extends downwardly in a direction away from the housing 10, so that the water injection inlet 52 can play a role in guiding flow, which can improve the water injection efficiency to a certain extent.

[0072] Reference Figure 1-Figure 4 According to some embodiments of the present invention, the water injection component 50 also has a storage position, and the water injection component 50 can move between the water injection position and the storage position. Through this arrangement, the position of the water injection component 50 can be adjusted according to the use needs. When the amount of water in the water tank 30 is insufficient, the water injection component 50 moves to the water injection position, and water is injected through the water injection inlet 52 of the water injection component 50. The water injected through the water injection inlet 52 flows into the water injection cavity 51, and then flows into the water tank 30 through the water injection outlet 53 and the water replenishment hole 33, so that water can be injected into the water tank 30. When the water injection operation is not required, the water injection component 50 can be moved to the storage position.

[0073] Reference Figure 1 According to some embodiments of the present invention, at the storage position, the water injection inlet 52 is hidden in the housing 10. After the water injection operation is completed, the water injection component 50 can be moved from the water injection position to the storage position, and the water injection inlet 52 is hidden in the housing 10. Through this arrangement, by hiding the water injection inlet 52 inside the housing 10, dust outside the housing 10 can be prevented from entering the interior of the air treatment device 100 through the water injection inlet 52.

[0074] Optionally, the water injection component 50 can be moved between the storage position and the water injection position manually, which can eliminate the need for a driving mechanism for driving the water injection component 50 to move, reduce the number of components, and save costs to a certain extent.

[0075] Optionally, in the storage position, the water inlet 52 faces upward. When the water injection component 50 is in the storage position, the water injection inlet 52 is hidden in the housing 10 and faces upward. This arrangement can prevent the residual water in the water injection cavity 51 from flowing to other components in the housing 10 through the water injection inlet 52.

[0076] Optionally, in the storage position, the water injection component 50 blocks the operation port 17. When the water injection component 50 moves to the storage position, the water injection component 50 can block the injection operation port 17, thereby eliminating the need for an external storage structure of the housing 10, reducing the number of components and saving costs. At the same time, the operation process of the water injection component 50 is relatively simple.

[0077] Optionally, in the storage position, the water injection component 50 blocks the operation port 17, and the surface of the water injection component 50 exposed to the outside is the exposed surface 581, and the exposed surface 581 is flush with the outer surface of the housing 10 or the protrusion height of the exposed surface 581 from the outer surface of the housing 10 is less than 5 mm. When the water injection component 50 is in the storage position, the exposed surface 581 of the water injection component 50 is flush with the outer surface of the housing 10 or the protrusion height of the exposed surface 581 of the water injection component 50 from the outer surface of the housing 10 is less than 5 mm, which can ensure the flatness and integrity of the outer surface of the housing 10 to a certain extent, and can also make the structure of the whole machine compact and reduce the space occupied by the whole machine. At the same time, in the storage position, the exposed surface 581 of the water injection component 50 can also prevent the dust outside the housing 10 from entering the interior of the air treatment device 100 through the water injection inlet 52.

[0078] When the exposed surface 581 of the water injection component 50 is flush with the outer surface of the housing 10 , a certain operating gap can be set between the water injection component 50 and the inner wall of the operating port 17 to facilitate the operation of the water injection component 50 .

[0079] Reference Figure 1-Figure 5 According to some embodiments of the present invention, the water injection component 50 is rotatable between the water injection position and the storage position. When water needs to be injected into the water tank 30, the water injection component 50 is rotated to the water injection position. When the water injection is completed, the water injection component 50 is rotated to the storage position. The operation is simple and convenient.

[0080] For example, refer to Figure 7-Figure 8 In some embodiments of the present invention, the water injection component 50 can be rotatably connected to the inner wall of the casing 10, and a mounting protrusion 171 is provided on the inner wall of the casing 10, and a matching hole is formed on the mounting protrusion 171. The outer wall of the water injection component 50 is provided with a matching shaft 591, and the matching shaft 591 is rotatably passed through the matching hole, so that the water injection component 50 can be rotatably connected to the inner wall of the casing 10.

[0081] Reference Figure 1-Figure 5 According to some embodiments of the present invention, the rotation angle of the water injection component 50 between the water injection position and the storage position is 30° to 90°. With this arrangement, the rotation stroke of the water injection component 50 between the water injection position and the storage position can be relatively short, which is convenient for operation.

[0082] For example, the rotation angle of the water injection component 50 between the water injection position and the storage position is 40° to 60° to facilitate operation.

[0083] Reference Figure 7-Figure 8 According to some embodiments of the present invention, the electric control component is used to detect the position of the water injection component 50, and when the water injection component 50 is detected to be in the water injection position, the water supply valve 32 is controlled to cut off the water supply channel 31. By setting the electric control component, the function of detecting the position of the water injection component 50 can be achieved. When the electric control component detects that the water injection component 50 is in the water injection position, the water supply valve 32 is controlled to cut off the water channel, which can prevent the water in the water tank 30 from flowing into the water tank 41 during the water injection process, resulting in the overflow of the water tank 41 due to excessive water in the water tank 41.

[0084] Reference Figure 7-Figure 8 According to some embodiments of the present invention, the electric control component includes a position sensor 70 and a control module 71, the position sensor 70 is electrically connected to the control module 71, and the position sensor 70 is used to detect the position of the water injection component 50. Through this configuration, when the water tank 30 needs to be filled with water, the water injection component 50 moves to the water injection position, the position sensor 70 will detect the position of the water injection component 50, and convert the position signal into an electrical signal to transmit to the control module 71 electrically connected thereto, and the control module 71 will then transmit the electrical signal to the water supply valve 32, thereby controlling the water supply valve 32 to cut off the water supply channel 31, so as to prevent the water in the water tank 30 from flowing into the water tank 41 during the water injection process, resulting in the water tank 41 overflowing due to excessive water in the water tank 41.

[0085] Reference Figure 7-Figure 8According to some embodiments of the present invention, the position sensor 70 includes a first sensor element 701 and a second sensor element 702. The first sensor element 701 is disposed on the water injection component 50, and the second sensor element 702 is disposed on the housing 10 and adjacent to the operation port 17. The spacing between the first sensor element 701 and the second sensor element 702 at the water injection position is a first spacing, and the spacing between the first sensor element 701 and the second sensor element 702 at the storage position is a second spacing, and the first spacing is different from the second spacing. The first sensor element 701 is disposed on the water injection component 50 and moves with the movement of the water injection component 50. The second sensor element 702 is disposed on the housing 10 and has a relatively fixed position. The water injection component 50 moves between the storage position and the water injection position, so that the spacing between the first sensor element 701 and the second sensor element 702 changes continuously with the movement of the water injection component 50.

[0086] When the water filling component 50 moves to the water filling position, the distance between the first sensor element 701 and the second sensor element 702 is the first distance. At this time, the position sensor 70 can detect that the water filling component 50 is in the water filling position, and convert this position signal into an electrical signal and transmit it to the control module 71 electrically connected thereto. The control module 71 then transmits the electrical signal to the water supply valve 32, thereby controlling the water supply valve 32 to cut off the water supply channel 31, so as to prevent the water in the water tank 30 from flowing into the water tank 41 during the water filling process, resulting in overflow of the water tank 41 due to excessive water in the water tank 41.

[0087] When the water injection component 50 moves to the storage position, the distance between the first sensor element 701 and the second sensor element 702 is the second distance. At this time, the position sensor 70 can detect that the water injection component 50 is in the storage position and convert the position signal into an electrical signal and transmit it to the control module 71 electrically connected thereto.

[0088] Through this arrangement, the structure of the position sensor 70 is simple, and the position signal of the water injection component 50 can be quickly detected, and the position signal of the water injection component 50 can be quickly fed back to the control module 71 electrically connected to the position sensor 70, thereby controlling the movement of the water injection valve.

[0089] Optionally, the first spacing is greater than the second spacing. During the movement of the water injection component 50 from the storage position to the water injection position, the first sensor element 701 provided at the water injection component 50 gradually moves away from the second sensor element 702 provided at the housing 10 as the water injection component 50 moves. When the water injection component 50 is at the water injection position, the spacing between the first sensor element 701 and the second sensor element 702 is the first spacing. During the movement of the water injection component 50 from the water injection position to the storage position, the first sensor element 701 provided at the storage position gradually moves closer to the second sensor element 702 provided at the housing 10 as the water injection component 50 moves. When the water injection component 50 is at the storage position, the spacing between the first sensor element 701 and the second sensor element 702 is the second spacing, so the first spacing is greater than the second spacing. Through this arrangement, the first spacing and the second spacing provide different position signals.

[0090] Optionally, one of the first sensing element 701 and the second sensing element 702 can be a transmitter and the other can be a receiver. The position sensor 70 can use a photoelectric or ultrasonic type. When the above-mentioned first spacing and the second spacing are different, the photoelectric signal or ultrasonic signal detected by the position sensor 70 is different, so as to facilitate the position sensor 70 to capture and detect the position signal.

[0091] Optionally, one of the first sensing element 701 and the second sensing element 702 is a Hall element and the other is a permanent magnet. When the first spacing and the second spacing are different, the magnetic field signals detected by the position sensor 70 are different, so as to facilitate the position sensor 70 to capture and detect the position signal.

[0092] Reference Figure 4-Figure 5 According to some embodiments of the present invention, when the water injection component 50 is in the storage position, the control module 71 controls the water supply valve 32 to conduct or cut off the water supply channel 31 according to the functional instruction, and the functional instruction includes a humidification start instruction and a humidification stop instruction. When the air treatment device 100 starts the humidification function, and the position sensor 70 detects that the water injection component 50 is in the water injection position, the control module 71 receives the humidification start instruction, and the control module 71 will conduct the water supply channel 31 according to the functional instruction and the electrical signal of the position sensor 70, so that the water in the water tank 30 continues to flow into the water tank 41 through the water supply channel 31 to ensure that there is enough water in the water tank 41 to complete the humidification function. When the air treatment device 100 stops the humidification function, the control module 71 receives the humidification stop instruction, and will cut off the water supply channel 31 according to the functional instruction, so that the water in the water tank 30 cannot flow into the water tank 41 through the water supply channel 31. After the water in the water tank 41 is consumed, the air treatment device 100 no longer humidifies the air.

[0093] Reference Figure 3 and Fig.11According to some embodiments of the present invention, an elastic protrusion 54 is provided on the outer surface of the water injection component 50, and in the storage position, the elastic protrusion 54 abuts against the inner wall of the operating port 17. When the water injection component 50 is in the storage position, the elastic protrusion 54 is in a compressed state and abuts against the inner wall of the operating port 17. The elastic protrusion 54 is fixed to the inner wall of the operating port 17 by friction, so that the water injection component 50 can be stably maintained in the storage position. When the water injection component 50 is in the water injection position, the elastic protrusion 54 is out of contact with the inner wall of the operating port 17, and the elastic protrusion 54 is reset from the compressed state. The elastic protrusion 54 can facilitate the fixation and movement of the water injection component 50, and at the same time, the structure is simple and easy to operate.

[0094] Reference Fig. 9 According to some embodiments of the present invention, an exhaust structure 35 is provided at the upper end of the water tank 30. By providing the exhaust structure 35, the air in the water tank 30 can be communicated with the air outside the water tank 30. When the water tank 30 is filled with water, the air in the water tank 30 can be discharged to the outside of the water tank 30 through the exhaust structure 35, thereby making the water filling process smoother and improving the water filling efficiency to a certain extent.

[0095] Reference Fig. 9 According to some embodiments of the present invention, at the water filling position, the upper end surface of the exhaust structure 35 is higher than the water filling outlet 53. During the water filling operation of the water tank 30, when the water in the water tank 30 is sufficient, the water filling is not stopped in time, resulting in too much water being filled into the water tank 30. The water in the water tank 30 will overflow from the water filling outlet 53 of the water filling component 50, but will not overflow from the upper end surface of the exhaust structure 35. Through this arrangement, it is possible to avoid the situation where the water in the water tank 30 overflows from the exhaust structure 35 when the water in the water tank 30 is filled with too much water, and the safety of the whole machine can be improved to a certain extent.

[0096] Reference Fig. 9 According to some embodiments of the present invention, the exhaust structure 35 includes an exhaust hole 351 and an exhaust pipe 352. The exhaust hole 351 is formed at the top of the water tank 30, and the exhaust pipe 352 extending upward is connected to the exhaust hole 351. By arranging the exhaust hole 351 at the top of the water tank 30, it can be convenient to connect with the exhaust pipe 352, and at the same time, it can be convenient for the air in the water tank 30 to be discharged through the exhaust hole 351, thereby facilitating the water filling process. The exhaust hole 351 is connected to the exhaust pipe 352 extending upward, and the upper end surface of the exhaust pipe 352 is higher than the water filling outlet 53, so that when the water in the water tank 30 is overfilled, it can overflow through the water filling outlet 53 of the water filling component 50, thereby avoiding the situation that the water in the water tank 30 overflows from the exhaust pipe 352, and improving the safety of the whole machine to a certain extent.

When the water injection component 50 is at the water injection position, the water injection outlet 53 of the water injection component 50 is butted against the water inlet end of the water supply pipe 34, so that the water of the water injection component 50 can enter the water tank 30 through the water supply pipe 34, and the water supply pipe 34 has the functions of connection and diversion.

[0098] Reference Fig. 9 and Fig.11 According to some embodiments of the present invention, a matching convex ring 55 is formed on the outer circumference of the water injection outlet 53. In the water injection position, the matching convex ring 55 is accommodated in the water inlet end of the water supply pipe 34. When the water injection component 50 is in the water injection position, the matching convex ring 55 is matched with and accommodated in the water inlet end of the water supply pipe 34, so that the water injection outlet 53 of the water injection component 50 is connected with the water supply pipe 34 and the water supply hole 33 of the water tank 30, ensuring that the water flow can smoothly flow from the water injection component 50 into the water tank 30. At the same time, the matching convex ring 55 can also play a certain sealing role, ensuring the connection effect of the connection between the water injection outlet 53 and the water supply pipe 34, and avoiding the occurrence of water leakage at the connection.

[0099] Reference Figure 1-Figure 4 , Fig. 9 and Fig.11 According to some embodiments of the present invention, the water injection component 50 also has a storage position, and the water injection component 50 is movable between the water injection position and the storage position. In the storage position, the water injection outlet 53 is disengaged from the water inlet pipe. The water injection component 50 is movable between the water injection position and the storage position, and the position of the water injection component 50 can be adjusted according to the use needs. When the amount of water in the water tank 30 is insufficient, the water injection component 50 moves to the water injection position, and water is injected through the water injection inlet 52 of the water injection component 50. The water injected through the water injection inlet 52 flows into the water injection cavity 51, and then flows into the water tank 30 through the water injection outlet 53 and the water replenishment hole 33, so that water can be injected into the water tank 30. When no water injection operation is required, the water injection component 50 can be moved to the storage position. When the water injection component 50 is in the storage position, the water injection outlet 53 is disengaged from the water replenishment pipe 34, and the water injection outlet 53 is no longer connected to the water inlet end of the water replenishment pipe 34, which can prevent the residual water in the water injection component 50 from entering the water inlet pipe through the water injection outlet 53.

[0100] Reference Fig. 9 and Fig.11According to some embodiments of the present invention, in the storage position, the water injection component 50 blocks the water inlet end of the water supply pipe 34. Through this arrangement, the sealing effect of the water injection component 50 and the water supply pipe 34 can be ensured. When the water injection component 50 is in the storage position, it can prevent the residual water in the water injection component 50 from entering the water inlet pipe through the water injection outlet 53. At the same time, it can prevent the dust outside the housing 10 from entering the inside of the housing 10 through the water injection component 50 and the water supply pipe 34.

[0101] Reference Figure 1-Figure 4 , Fig. 9 and Fig.11 According to some embodiments of the present invention, the water injection component 50 is rotatable between the water injection position and the storage position. The outer surface of the water injection component 50 includes a matching surface 56 extending in an arc shape. The water injection outlet 53 is formed on the matching surface 56. The matching surface 56 also forms a sealing protrusion 57. The sealing protrusion 57 is spaced apart from the water injection outlet 53 in the extending direction of the matching surface 56. In the storage position, the sealing protrusion 57 is accommodated in the water inlet end of the water supply pipe 34 to block the water inlet end of the water supply pipe 34. The matching surface 56 extending in an arc shape plays a role in guiding and avoiding the water inlet end of the water supply pipe 34, and can ensure the smoothness of the water injection component 50 when rotating between the water injection position and the storage position. A sealing protrusion 57 is formed on the mating surface 56. When the water injection component 50 is in the storage position, the sealing protrusion 57 cooperates with the water inlet end of the water supply pipe 34. The sealing protrusion 57 is accommodated in the water inlet end of the water supply pipe 34 to seal the water inlet end, thereby ensuring a sealing effect between the water inlet end of the water supply pipe 34 of the water tank 30 and the water injection component 50 when in the storage position, thereby preventing dust outside the casing 10 from entering the interior of the casing 10 through the water injection component 50 and the water supply pipe 34.

The water injection chamber 51 includes the water inlet chamber 511 and the water outlet chamber 512. The cross-sectional area of ​​the water inlet chamber 511 increases from bottom to top. Through this arrangement, the cross-sectional area of ​​the water inlet chamber 511 is larger at the outside of the housing 10, so there is enough operating space, which can facilitate the water injection operation. The cross-sectional area of ​​the water inlet chamber 511 is gradually reduced at the water inlet end close to the water supply pipe 34, which can ensure the diversion effect of the water injection chamber 51, optimize the flow path of water flow inside the water injection component 50, and improve the water injection efficiency.

The rotation angle of the water injection component 50 between the water injection position and the storage position is 30° to 90°. The water injection component 50 can be rotated according to usage needs. When water injection is required, the water injection component 50 is rotated to the water injection position. When the water injection operation is completed, the water injection component 50 is rotated to the storage position to block the operation port 17.

[0126] The electric control component is used to detect the position of the water injection component 50, and when it is detected that the water injection component 50 is in the water injection position, the water supply valve 32 is controlled to cut off the water supply channel 31. The electric control component includes a position sensor 70 and a control module 71. The control module 71 is located above the water tank 30 and close to the rear housing 11. The position sensor 70 is electrically connected to the control module 71. The position sensor 70 is used to detect the position of the water injection component 50. The position sensor 70 includes a first sensor element 701 and a second sensor element 702. The first sensor element 701 is provided at the water injection component 50, and the second sensor element 702 is provided at the housing 10 and adjacent to the operation port 17. The spacing between the first sensor element 701 and the second sensor element 702 at the water injection position is a first spacing, and the spacing between the first sensor element 701 and the second sensor element 702 at the storage position is a second spacing, and the first spacing is different from the second spacing. During the movement of the water injection component 50 from the storage position to the water injection position, the first sensor element 701 provided on the water injection component 50 gradually moves away from the second sensor element 702 provided on the housing 10 as the water injection component 50 moves. When the water injection component 50 is in the water injection position, the distance between the first sensor element 701 and the second sensor element 702 is the first distance. During the movement of the water injection component 50 from the water injection position to the storage position, the first sensor element 701 provided on the storage position gradually moves closer to the second sensor element 702 provided on the housing 10 as the water injection component 50 moves. When the water injection component 50 is in the storage position, the distance between the first sensor element 701 and the second sensor element 702 is the second distance, so the first distance is greater than the second distance.

[0127] When the water injection component 50 is in the storage position, the control module 71 controls the water supply valve 32 to cut off the water supply channel 31, and the water in the water tank 30 cannot flow into the water tank 41 through the water supply channel 31. When the water injection component 50 is in the storage position, the control module 71 controls the water supply valve 32 to open or cut off the water supply channel 31 according to the functional instruction. The functional instruction includes a humidification start instruction and a humidification stop instruction. When the functional instruction is a humidification start instruction, the control module 71 controls the water supply valve 32 to open the water supply channel 31, and the water in the water tank 30 flows into the water tank 41 through the water supply channel 31. When the functional instruction is to stop the humidification function, the control module 71 controls the water supply valve 32 to cut off the water supply channel 31, and the water in the water tank 30 will stop flowing into the water tank 41.

[0128] The outer surface of the water injection component 50 is provided with an elastic protrusion 54. In the storage position, the elastic protrusion 54 abuts against the inner wall of the operation port 17 and fixes the position of the water injection component 50 by friction. A matching protrusion 55 is formed on the outer periphery of the water injection outlet 53 of the water injection component 50. In the water injection position, the matching protrusion 55 is accommodated in the water inlet end of the water supply pipe 34. When the water injection component 50 rotates to the storage position, the water injection outlet 53 is disengaged from the water inlet pipe. When the water injection component 50 rotates to the water injection position, the water injection component 50 blocks the water inlet end of the water supply pipe 34. The outer surface of the water injection component 50 includes a matching surface 56 extending in an arc shape. The water injection outlet 53 is formed on the matching surface 56. The matching surface 56 also forms a sealing protrusion 57. The sealing protrusion 57 is spaced apart from the water injection outlet 53 in the extending direction of the matching surface 56. In the storage position, the sealing protrusion 57 is accommodated in the water inlet end of the water supply pipe 34 to block the water inlet end of the water supply pipe 34. The water injection component 50 includes a main body 58 and a matching portion 59. A water injection inlet 52 is formed at the top of the main body 58. The matching portion 59 is connected to the side of the main body 58 away from the operation port 17. The matching portion 59 is formed with a matching surface 56. A water inlet chamber 511 is formed in the main body 58. A water outlet chamber 512 connected to the water inlet chamber 511 is formed in the matching portion 59. The water injection chamber 51 includes a water inlet chamber 511 and a water outlet chamber 512. The cross-sectional area of ​​the water inlet chamber 511 increases from bottom to top.

[0129] The water tank 30 is located above the water tank 41 and below the control module 71. An exhaust structure 35 is provided at the upper end of the water tank 30. The exhaust structure 35 includes an exhaust hole 351 and an exhaust pipe 352. The exhaust port is formed at the middle of the top of the water tank 30. The exhaust pipe 352 is connected to the exhaust port, and the upper end surface of the exhaust pipe 352 is higher than the water injection outlet 53 of the water injection component 50. When water is added to the water tank 30, the water tank 30 can be exhausted through the exhaust hole 351 and the exhaust pipe 352 to ensure a smoother water addition process. The outer wall of the water tank 30 is provided with a guide groove 36, which is used to guide the water on the outer surface of the water tank 30 into the water tank 41. The guide groove 36 includes a collecting area 37 and a guide section 38. The collecting area 37 surrounds the outer peripheral side of the water replenishment hole 33. The guide section 38 is connected to the collecting area 37. The water replenishment hole 33 is located at the top of the water tank 30 and is located on the side close to the water injection component 50. The collecting area 37 surrounds the outer peripheral side of the water replenishment hole 33. The guide section 38 can be divided into a first guide section 381 and a second guide section 382. The second guide section 382, ​​the first guide section 381 is located at the top of the water tank 30 and extends to the edge near the water injection component 50, the second guide section 382 is located on the side of the water tank 30 and extends to the edge of the bottom of the water tank 30, the first guide section 381 is connected to the second guide section 382 at the edge near the water injection component 50, the water dripping to the top of the water tank 30 is collected in the collection area, and then flows into the water tank 41 below the water tank 30 through the first guide section 381 and the second guide section 382.

[0130] The side plate of the water tank component 40 is formed with an overflow hole 42 connected to the water tank 41, and an overflow pipe 43 is connected to the overflow hole 42. The overflow pipe 43 is used to discharge the water overflowing from the water tank 41. The overflow hole 42 is arranged on the side wall of the water tank component 40 and the lowest point of the overflow port is higher than the preset humidification liquid level in the water tank 41 to ensure that the liquid level in the water tank 41 is always not lower than the preset humidification liquid level, so that there is always enough water in the water tank 41 for humidification, thereby ensuring the humidification effect of the humidification module 21. When the drain valve fails and cannot be closed, it can ensure that the water continuously flowing into the water tank 41 from the water tank 30 can be discharged through the overflow pipe 43 at the overflow port.

[0131] The heat exchange and air supply unit 80 includes a heat exchanger component and a water receiving pan 81. The water receiving pan 81 is located below the heat exchanger component. A drain pipe 82 is connected to the water receiving pan 81. The overflow pipe 43 is connected and communicated with the drain pipe 82. The drain pipe 82 plays a diversion role. After the condensed water is collected in the water receiving pan 81, it flows out through the drain pipe 82. The overflow pipe 43 is communicated with the drain pipe 82. The drain pipe 82 is provided with a connecting branch pipe 83 for connecting with the overflow pipe 43. The connecting branch pipe 83 is arranged on the side wall of the drain pipe 82 and extends obliquely upward. The highest position of the connecting branch pipe 83 is lower than the lowest position of the overflow port. When the liquid level in the water tank 41 is higher than the overflow port, the excess water in the water tank 41 will flow into the drain pipe 82 through the overflow pipe 43 and then be discharged through the drain pipe 82.

[0132] When the air conditioner starts the humidification function, the air handling unit 20 is in working state, and the water injection component 50 rotates to the storage position. In this process, the first sensor element 701 placed in the storage position gradually approaches the second sensor element 702 set in the housing 10 with the movement of the water injection component 50, until the distance between the first sensor element 701 and the second sensor element 702 reaches the second spacing. At this time, the position sensor 70 can detect that the water injection component 50 is in the storage position through the second spacing position signal, and convert the second spacing position signal into an electrical signal to the control module 71 electrically connected thereto. The control module 71 receives the humidification start instruction and controls the water supply valve 32 to conduct the water supply channel 31, so that the water in the water tank 30 flows into the water tank 41 through the water supply channel 31. In the humidification state, the air passing through the first air inlet 13 passes through the lower air duct 23 and is humidified by the wet film 62 at the water tank 41, and the humidified air is released from the first air outlet 14 to complete the humidification function. When the air conditioner turns off the humidification function, the control module 71 receives the humidification shut-off instruction and controls the water supply valve 32 to cut off the water supply channel 31, and the water in the water tank 30 stops flowing into the water tank 41. After the water in the water tank 41 is consumed, the air treatment device 100 no longer humidifies the air.

[0133] When the amount of water in the water tank 30 is insufficient and the water tank 30 needs to be filled with water, the water filling component 50 is moved from the storage position to the water filling position, and the first sensor element 701 disposed on the water filling component 50 gradually moves away from the second sensor element 702 disposed on the casing 10 as the water filling component 50 moves, until the distance between the first sensor element 701 and the second sensor element 702 reaches a first spacing. At this time, the position sensor 70 can detect that the water filling component 50 is in the water filling position through the position signal of the first spacing, and convert the position signal of the first spacing into an electrical signal and transmit it to the control module 71 electrically connected thereto. The control module 71 will control the water filling valve to cut off the water supply channel 31 until the air conditioner starts the humidification function again. During this process, the water supply channel 31 is always in a cut-off state.

[0134] Through this arrangement, when the water tank 30 of the air treatment device 100 is filled with water, water can be directly filled into the water tank 30 through the water filling component 50 at the position of the operation port 17, without the need to disassemble, carry and assemble the water tank 30, which is simple to operate and convenient to use. At the same time, the electric control component can control the water supply valve 32, and can conveniently control the conduction or cutoff effect of the water supply channel 31.
