[0066] Reference Fig. 9 According to some embodiments of the present invention, the water receiving tray 91 is located above the water tank part 40, and the lower end of the drain pipe 92 is the discharge end, which is located in the water receiving tank 81. Through this arrangement, it is convenient for the water in the water receiving tray 91 to flow into the water receiving tank 81 through the drain pipe 92. The discharge end of the drain pipe 92 is arranged in the water receiving tank 81, so that when the drain pipe 92 drains water to the water receiving tank 81, the discharged water will not leak from the discharge end to the outside of the water receiving tank 81, which can improve the safety of the whole machine to a certain extent.

[0067] Reference Figure 10-11 According to some embodiments of the present invention, the water receiving component 80 is connected to the water tank component 40. Through this arrangement, the installation and fixation of the water receiving component 80 and the water tank component 40 can be facilitated, and at the same time, the communication between the water receiving tank 81 and the humidification tank 41 can be facilitated.

[0068] Reference Figure 10-11 According to some embodiments of the present invention, the water receiving component 80 is integrally formed with the water tank component 40. The integrally formed water receiving component 80 and the water tank component 40 have better integrity and structural strength, and at the same time, can ensure the connection effect between the water receiving tank 81 and the humidification tank 41. In addition, the integrally formed part can simplify the production and assembly processes, and can improve production efficiency to a certain extent.

[0069] Reference Figure 10-11 According to some embodiments of the present invention, the water receiving component 80 is located on one side of the water tank component 40 in the horizontal direction. Through this arrangement, the water receiving tank 81 and the humidification tank 41 can be arranged in the horizontal direction, which can facilitate the mutual flow of water in the humidification tank 41 and the water receiving tank 81. At the same time, this arrangement method can facilitate the processing and assembly of the water receiving component 80 and the water tank component 40.

[0070] Reference Figure 10-11 According to some embodiments of the present invention, the water receiving component 80 is connected to the side wall of the water tank component 40, and the side wall of the water tank component 40 includes a common side wall 42, and the common side wall 42 is located between the water receiving tank 81 and the humidifying tank 41 and is formed with a connecting port 43, and the connecting port 43 connects the water receiving tank 81 and the humidifying tank 41. By providing the common side wall 42, the connection method of the water receiving component 80 and the humidifying component 60 is simple, which can facilitate the connection between the water receiving tank 81 and the humidifying tank 41, and the setting of the connecting structure is omitted. By providing the connecting port 43, when the amount of water in the humidifying tank 41 is too much, the water in the humidifying tank 41 enters the water receiving tank 81 through the connecting port 43, and the water from the water receiving tray 91 in the water receiving tank 81 can also enter the humidifying tank 41 through the connecting port 43.

[0071] Optionally, the lowest point of the communication port 43 may be slightly higher than the bottom wall of the humidification water tank 41 to ensure that there is a certain amount of water in the humidification water tank 41 to ensure the humidification effect of the humidification module 21 .

[0072] Reference Figure 10-11 According to some embodiments of the present invention, the water receiving component 80 is connected to an overflow pipe 82 and is formed with an overflow hole 83, and the overflow hole 83 connects the water receiving tank 81 and the overflow pipe 82. Through this arrangement, when the amount of water in the water receiving tank 81 is too much, the water in the water receiving tank 81 can flow out through the overflow pipe 82 at the overflow hole 83, thereby solving the problem of overflow of the water receiving tank 81 due to excessive water. In addition, when the amount of water in the humidification water tank 41 is too much, the water in the humidification water tank 41 will flow into the water receiving tank 81 and flow out through the overflow pipe 82 at the overflow hole, thereby solving the problem of overflow of the humidification water tank 41 due to excessive water, thereby improving the safety of the whole machine.

[0073] Optionally, the overflow pipe 82 may extend to the outdoors to discharge the water in the overflow pipe 82 to the outdoors.

[0074] Reference Figure 10-11 According to some embodiments of the present invention, when the liquid level in the water receiving tank 81 is higher than the preset height liquid level, the water in the water receiving tank 81 is discharged through the overflow hole 83, the water receiving component 80 is located on one side of the water tank component 40 along the horizontal direction, the water receiving tank 81 is connected to the humidifying tank 41 through the connecting port 43, and the bottom wall of the connecting port 43 is higher than the bottom wall of the humidifying tank 41 and lower than the preset height liquid level. Through this arrangement, when the liquid level in the water receiving tank 81 is higher than the preset height liquid level, the water in the water receiving tank 81 will flow out through the overflow pipe 82 at the overflow hole 83, which can solve the problem of overflow of the water receiving tank 81 due to excessive water. When there is too much water in the humidifying water tank 41, the water in the humidifying water tank 41 will flow into the water receiving tank 81 through the connecting port 43 until the liquid level in the water receiving tank 81 is higher than the preset height liquid level. Then, the water in the water receiving tank 81 will flow out through the overflow pipe 82 at the overflow hole 83, thereby solving the problem of overflow of the humidifying water tank 41 due to excessive water.

[0075] The bottom wall of the connecting hole is higher than the bottom wall of the humidifying water tank 41, which can ensure that there is a certain amount of water in the water receiving tank 81 to ensure the humidification effect of the humidifying module 21. The bottom wall of the connecting port 43 is lower than the preset height liquid level, so that the water in the water receiving tank 81 can flow into the humidifying water tank 41 through the connecting port 43, avoiding the water in the connecting tank from being directly discharged through the overflow hole 83, resulting in a waste of water resources.

[0076] Reference Figure 10-11According to some embodiments of the present invention, the bottom wall of the water receiving trough 81 is provided with an overflow boss 84, the overflow boss 84 is lower than the upper end surface of the water receiving trough 81, and an overflow hole 83 is formed on the upper surface of the overflow boss 84, the overflow hole 83 penetrates downwardly through the bottom wall of the water receiving trough 81, and the overflow pipe 82 is connected to the bottom of the water receiving component 80. By providing the overflow boss 84, the connection between the overflow hole 83 and the overflow pipe 82 can be facilitated, so that the structure of the overflow pipe 82 is simpler and the drainage effect is better. The upper end surface of the overflow boss 84 is the preset height liquid level. When the liquid level in the water receiving trough 81 is higher than the upper end surface of the overflow boss 84, the water in the water receiving trough 81 will flow out through the overflow pipe 82 at the overflow hole 83.

[0077] Optionally, the upper end surface of the overflow boss 84 is lower than the upper end surface of the water receiving tank 81, and can be higher than the lowest point of the communication port 43. When the liquid level in the water receiving tank 81 is lower than the lowest point of the communication port 43, the water in the water receiving tank 81 only flows in but does not flow out. The water in the water receiving tank 81 can be the water from the humidification tank 41 that flows in through the communication port 43 due to excess, can be the water discharged from the water receiving tray 91 through the drain pipe 92, or can be both the water flowing in from the humidification tank 41 and the water discharged from the water receiving tray 91.

[0078] When the liquid level in the water receiving tank 81 is higher than the lowest point of the communication port 43 , the water in the water receiving tank 81 can flow into the humidification tank 41 through the communication port 43 , so that the humidification component 60 can realize the humidification function.

[0079] When the liquid level in the water receiving tank 81 is higher than the upper surface of the overflow boss 84, that is, when the liquid level in the water receiving tank 81 is higher than the preset height liquid level, the water in the water receiving tank 81 will flow out through the overflow pipe 82 at the overflow hole 83, which can solve the problem of overflow of the water receiving tank 81 due to excessive water.

[0080] Reference Figure 4-Figure 5 According to some embodiments of the present invention, the water tank 30 has a water supply channel 31 for supplying water to the humidification water tank 41, and a water supply valve 32 for opening and closing the water supply channel 31 is provided in the water supply channel 31. Through this arrangement, the water supply and water supply stop functions of the water tank 30 to the humidification water tank 41 can be realized. When the water supply valve 32 opens the water supply channel 31, the water in the water tank 30 can flow into the humidification water tank 41 through the water supply channel 31. When the water supply valve 32 closes the water supply channel 31, the water in the water tank 30 will stop flowing into the humidification water tank 41. If the water supply valve 32 fails and cannot cut off the water supply channel 31, the water in the water tank 30 will continuously flow into the humidification water tank 41, resulting in excessive water in the humidification water tank 41. The water in the humidification water tank 41 will flow into the water receiving tank 81 connected to it, and flow out through the overflow pipe 82 at the overflow hole 83, which can solve the problem of overflow of the humidification water tank 41 due to excessive water, thereby improving the safety of the whole machine.

By setting the first filter element 851, the second filter element 852 and the third filter element 853, the filter structure 85 can achieve three-layer filtration of the condensed water, which can greatly improve the water quality of the condensed water, thereby improving the purification and humidification effect of the condensed water used for humidification on the air.

The discharge end of the drain pipe 92 is arranged in the water receiving area 86 of the water receiving tank 81, so that the discharged water will not leak from the discharge end to the outside of the water receiving tank 81 during the process of the drain pipe 92 draining water to the water receiving tank 81. The side wall of the filtering area 87 away from the water receiving area 86 is formed with a connecting port 43 connected to the humidifying tank 41. The water in the water receiving area 86 passes through the filtering structure 85 of the filtering area 87, is filtered and purified, and then flows into the humidifying tank 41 through the connecting port 43 for humidifying the air, which can ensure the humidifying effect of the humidifying component 60 on the air. At the same time, by setting up the filter area 87 , sufficient operating space can be provided, so that the filter structure 85 can be repaired and replaced conveniently in the filter area 87 .

With this arrangement, when the liquid level in the water receiving tank 81 is higher than the preset height liquid level, the water in the water receiving tank 81 will flow out through the overflow pipe 82 at the overflow hole 83, which can solve the problem of overflow of the water receiving tank 81 due to excessive water. The drain pipe 92 and the overflow boss 84 are respectively located at the two ends along the second direction. This arrangement can make full use of the space of the water receiving area 86, making the spatial arrangement of the drain pipe 92 and the overflow boss 84 more reasonable, and at the same time, can make the flow path of condensed water in the water receiving area 86 smoother.

[0087] Reference Figure 1-Figure 7 According to some embodiments of the present invention, the housing 10 is formed with an operation port 17, the water tank 30 has a water supply hole 33, and the humidification module 21 includes a water injection component 50. The operation port 17 is used for the water injection operation of the humidification module 21, and water can be directly injected into the humidification module 21 at the position of the operation port 17 without disassembling and carrying the water tank 30, which is simple to operate and convenient to use.

[0088] The water injection component 50 has a water injection cavity 51, a water injection inlet 52 and a water injection outlet 53 connected to the water injection cavity 51. The water injection component 50 has a water injection position. At 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 amount of water in the water tank 30 is insufficient, the water injection component 50 is in the water injection position, and 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.

[0089] 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.

[0090] Reference Figure 1-Figure 7 According 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.

[0091] 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.

[0092] 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.

[0093] Reference Figure 1-Figure 7According 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.

[0094] Reference Figure 1-Figure 7 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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 .

[0100] Optionally, 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, and 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.

[0101] Reference Figure 1-Figure 7 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.

[0102] Optionally, the rotation angle of the water injection component 50 between the water injection position and the storage position is 30° to 90°. Through 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.

[0103] 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.

[0104] For example, refer to Figure 6-Figure 7In 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.

[0105] Reference Figure 1-Figure 7 According to some embodiments of the present invention, the water tank 30 has a water supply channel 31 for supplying water to the humidification water tank 41, and a water supply valve 32 for conducting and cutting off the water supply channel 31 is provided in the water supply channel 31. At the water filling position, the water supply valve 32 cuts off the water supply channel 31. Through this arrangement, the water supply and water supply stop functions of the water tank 30 to the humidification water tank 41 can be realized. When the water supply component is in the storage position, the water supply valve 32 cuts off the water supply channel 31, and the water in the water tank 30 stops flowing into the humidification water tank 41, avoiding the situation that the water in the water tank 30 keeps flowing into the humidification water tank 41 during the water filling process.

[0106] Reference Figure 1-Figure 7 According to some embodiments of the present invention, it further includes an electric control component, which 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. The electric control component is used to detect the position of the water injection component 50, and control the water supply valve 32 to cut off the water supply channel 31 when the water injection component 50 is detected to be in the water injection position. 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 will be controlled to cut off the water channel, which can avoid the situation that the water in the water tank 30 keeps flowing into the humidification tank 41 during the water injection process, resulting in the humidification tank 41 overflowing due to excessive water in the humidification tank 41. At the same time, the electric control component can control the water supply valve 32 to conduct or cut off the water supply channel 31, thereby controlling the water supply and stop of the water tank 30 to the humidification tank 41.

[0107] Optionally, 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 setting, 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 avoid the water in the water tank 30 from flowing into the humidification tank 41 during the water injection process, resulting in the humidification tank 41 overflowing due to excessive water in the humidification tank 41.

[0108] Optionally, 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, 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, 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, the position is relatively fixed, 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.

[0109] When the water injection component 50 moves to the water injection 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 injection component 50 is in the water injection 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 humidification water tank 41 during the water injection process, resulting in overflow of the humidification water tank 41 due to excessive water in the humidification water tank 41.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] Reference Figure 1-Figure 7 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 open 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 open 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 humidification tank 41 through the water supply channel 31, so as to ensure that there is enough water in the humidification tank 41 to complete the humidification function. When the air treatment device 100 stops the humidification function, the control module 71 receives the stop humidification instruction and will cut off the water supply channel 31 according to the function instruction, so that the water in the water tank 30 cannot flow into the humidification water tank 41 through the water supply channel 31. After the water in the humidification water tank 41 is consumed, the air treatment device 100 no longer humidifies the air.

[0116] Reference Figure 1-Figure 8 and Fig.12 According to some embodiments of the present invention, a water supply pipe 34 is connected to the water supply hole 33; wherein, in the water injection position, the water injection outlet 53 is butted against the water inlet end of the water supply pipe 34; in the storage position, the water injection outlet 53 is disengaged from the water inlet pipe. When the water injection component 50 is in 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 function of connection and diversion. When the water injection component 50 is in the storage position, the water outlet is disengaged from the water supply pipe 34, and the water injection outlet 53 is no longer connected to the water inlet end of the water supply pipe 34, which can prevent the residual water of the water injection component 50 from entering the water inlet pipe through the water injection outlet 53.

[0117] Optionally, a matching convex ring 55 is formed on the outer circumference of the water injection outlet 53, and 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 matches with and is 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 water can flow smoothly 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 water leakage at the connection.

[0118] Reference Figure 1-Figure 8 and Fig.12 According 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.

[0119] Optionally, 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, and the matching surface 56 is also formed with 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, and 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.

[0120] For example, in some optional embodiments of the present invention, referring to Fig.12 The water injection component 50 may include a main body 58 and a matching part 59. A water injection inlet 52 is formed on the top of the main body 58. The matching part 59 is connected to the side of the main body 58 away from the operation port 17. The matching part 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 part 59. 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.

[0121] Reference Figure 8 According to some embodiments of the present invention, an exhaust structure 35 is provided at the upper end of the water tank 30. 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.

[0122] Optionally, 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, thereby improving the safety of the whole machine to a certain extent.

[0123] Optionally, the water tank 30 is located above the humidification water tank 41, and 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 humidification water tank 41. The guide groove 36 has a diversion function. By providing the guide groove 36, the water dripping to the outer surface of the water tank 30 during water filling can flow into the humidification water tank 41 through the guide groove 36, which can reduce the waste of resources to a certain extent. At the same time, it can prevent the water dripping to the outer surface of the water tank 30 from flowing into other components inside the casing 10, such as the fan, and can improve the safety of the whole machine to a certain extent.

[0124] Optionally, the water replenishment hole 33 is formed at the top of the water tank 30, and 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, and the guide section 38 is connected to the collecting area 37 and at least partially extends in the up-down direction. The water replenishment hole 33 is located at the top of the water tank 30, which can facilitate the connection between the water tank 30 and the water injection component 50. The collecting area 37 has a collection effect on the water dripping to the outer surface of the water tank 30 during the water injection process, and then flows into the humidification tank 41 through the guide section 38.

The first direction intersects with the second direction and is parallel to the horizontal direction.

[0137] The water injection component 50 has a storage position and a water injection position. When the water injection component 50 is in the water injection position, at least part of the water injection inlet 52 extends out of the casing 10 through the operating port 17. The operating port 17 is located on the right side of the lower panel 122. The water injection inlet 52 extends upward and tilted downward in a direction away from the casing 10.

[0138] The water injection component 50 can move between the water injection position and the storage position. When the water injection component 50 is in the storage position, the water injection inlet 52 is hidden in the housing 10. At this time, the water injection inlet 52 is facing upward in the housing 10 and blocks the operation port 17. The surface of the water injection component 50 exposed to the outside of the housing 10 is the exposed surface 581. The exposed surface 581 is flush with the outer surface of the housing 10 or the exposed surface 581 protrudes from the outer surface of the housing 10 by less than 5 mm. The water injection component 50 can rotate between the water injection position and the storage position. 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 the use 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.

[0139] 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.

[0140] 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.

[0141] 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 humidification 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 conduct 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 conduct the water supply channel 31, and the water in the water tank 30 flows into the humidification 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 humidification water tank 41.

[0142] 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.

[0143] The outer surface of the water injection component 50 includes a matching surface 56 extending in an arc shape, and 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. The top of the main body 58 is formed with a water injection inlet 52. 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 cavity 511 is formed in the main body 58. A water outlet cavity 512 communicating with the water inlet cavity 511 is formed in the matching portion 59. The water injection cavity 51 includes the water inlet cavity 511 and the water outlet cavity 512. The cross-sectional area of ​​the water inlet cavity 511 increases from bottom to top.

[0144] The water tank 30 is located above the humidification 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.

[0145] 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 to the humidification 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 humidification water tank 41 below the water tank 30 through the first guide section 381 and the second guide section 382.

[0146] 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 position signal of the second spacing, and convert the position signal of the second spacing into an electrical signal and transmit it 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 humidification 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 at the humidification 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 a command to turn off the humidification, 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 humidification tank 41. After the water in the humidification tank 41 is consumed, the air treatment device 100 no longer humidifies the air.

[0147] 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.

[0148] With 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.

[0149] The water tank 30 supplies water to the humidification water tank 41 to ensure that the humidification water tank 41 has sufficient water for humidification. The water receiving tank 81 is connected to the humidification water tank 41. When the water volume of the humidification water tank 41 is too much or the water supply valve 32 is damaged, the excess water in the humidification water tank 41 will flow into the water receiving tank 81 connected thereto, thereby solving the problem of overflow of the humidification water tank 41 due to excessive water volume and improving the safety of the whole machine.

[0150] At the same time, the condensed water generated by the heat exchanger components during the cooling or heating process can be gathered at the water receiving tray 91, and the water in the water receiving tray 91 can be drained to the water receiving tank 81 through the drain pipe 92. The water introduced into the water receiving tank 81 is purified and filtered by the filter structure 85, and then can flow into the humidification tank 41 connected to the water receiving tank 81 for humidification. Therefore, the air treatment device 100 can realize the recovery and reuse of condensed water to a certain extent. By using the water generated by the heat exchanger components during operation to humidify the air, the number of times the water tank 30 is filled can be reduced to a certain extent.

[0151] Through this arrangement, the condensed water generated by the heat exchanger components during the refrigeration process can be recovered through the water receiving tank 81 and flow into the humidification water tank 41 connected thereto, so that the air treatment device 100 can use the condensed water to humidify the air, thereby realizing the reuse of the condensed water, saving resources while also reducing the number of times the water tank 30 is filled with water.
