[0117] At present, the air treatment products on the market are diversified, however, the existing air treatment devices have single structure, the use mode is relatively single, and the user experience is poor.

[0118] In view of this, the air treatment device can be used alone, and is also suitable for being mounted in air conditioners, purifiers, air machines and other equipment. The air conditioner can be a split type air conditioner, such as a floor air conditioner, a wall-mounted air conditioner, or an integrated air conditioner, such as a window air conditioner, a mobile air conditioner, etc. The air treatment device can humidify, purify, and fragrance the air. The specific structure of the air treatment device is described in detail below.

[0119] Please refer to Figures 3 to 7 The air treatment device 100 includes a housing 1, a purification module 2, a humidification module 3, and a switch door mechanism 4. The housing 1 forms an air inlet 11, an air outlet 12, a purification air duct 13 and a humidification air duct 14 formed between the air inlet 11 and the air outlet 12. The purification module 2 is arranged in the purification air duct 13 to guide the airflow through the purification air duct 13 and purify it. The humidification module 3 is arranged in the humidification air duct 14 to guide the airflow through the humidification air duct 14 and humidify it. The switch door mechanism 4 is arranged in the housing 1. The switch door mechanism 4 selects to open at least one of the purification air duct 13 and the humidification air duct 14 to define the airflow introduced from the air inlet 11 to flow through the purification air duct 13 and / or the humidification air duct 14, and to be discharged through the air outlet 12.

[0120] In the technical solution provided by the present application, the housing 1 forms a purification air duct 13 and a humidification air duct 14. The purification module 2 is arranged in the purification air duct 13 to guide the airflow through the purification air duct 13 and purify it. The humidification module 3 is arranged in the humidification air duct 14 to guide the airflow through the humidification air duct 14 and humidify it. The switch door mechanism 4 selects to open at least one of the purification air duct 13 and the humidification air duct 14 to define the airflow introduced from the air inlet 11 to flow through the purification air duct 13 and / or the humidification air duct 14. When the airflow from the air inlet 11 is only introduced into the purification air duct 13, only the purification mode of the air treatment device 100 can be opened. When the airflow from the air inlet 11 is only introduced into the humidification air duct 14, only the humidification mode of the air treatment device 100 can be opened. When the airflow from the air inlet 11 is introduced into the purification air duct 13 and the humidification air duct 14 at the same time, the purification mode and the humidification mode of the air treatment device 100 can be opened at the same time. The use mode of the air treatment device 100 is more, which improves the user experience.

[0121] It should be noted that the purification air duct 13 and the humidification air duct 14 formed in the housing 1 can be two independent air ducts, two air ducts with partial overlap, or a shared air duct. The above embodiments are within the scope of the present application.

[0122] When the air flow flows through the purification air duct 13, the blocking of the purification air duct 13 can be realized by setting the switch structure in the purification air duct 13, and the blocking of the humidification air duct 14 can be realized by setting the switch structure in the humidification air duct 14. The blocking position can be any position on the air duct, and is not specifically limited.

[0123] In an embodiment, the purification air duct 13 is formed with a first gate 21, the humidification air duct 14 is formed with a second gate 31, and the switch door mechanism 4 includes a first switch door mechanism 4a for opening or closing the first gate 21 and a second switch door mechanism 4b for opening or closing the second gate 31. The switch door structure is set in the corresponding gate to realize the on-off of the respective air duct, and the opening and closing of the purification air duct 13 and the humidification air duct 14 are facilitated.

[0124] When considering that the purification air duct 13 and the humidification air duct 14 are associated, for example, there is an overlapping part, in order to enable the purification air duct 13 and the humidification air duct 14 to be controlled respectively, in an embodiment of the present application, the switch door mechanism 4 is set in the non-overlapping part of the purification air duct 13 and the humidification air duct 14 to realize independent control of the opening and closing.

[0125] Specifically, the purification module 2 is formed with a purification passage 22 on the purification air duct 13, the purification passage 22 includes a first purification passage section 221 extending upward and downward and a second purification passage section 222 laterally communicating with the first purification passage section 221, the humidification module 3 is formed with a humidification passage 32 on the humidification air duct 14, the air outlet end of the humidification passage 32 communicates with the lower end of the first purification passage section 221 upward, the communication part of the second purification passage section 222 and the first purification passage section 221 forms the first gate 21, and the lower end opening of the first purification passage section 221 forms the second gate 31. In this way, the on-off of the humidification air duct 14 can be realized by only controlling the on-off of the humidification passage 32 in the humidification module 3, and the on-off of the purification air duct 13 can be realized by only controlling the on-off of the second purification passage section 222, facilitating the setting of the switch door mechanism 4.

[0126] Further, in an embodiment, the purification module 2 includes a purification mounting bracket 23, the purification passage 22 is formed in the purification mounting bracket 23, and the first switch door mechanism 4a and the second switch door mechanism 4b are both arranged on the purification mounting bracket 23. The first switch door mechanism 4a and the second switch door mechanism 4b are simultaneously mounted on the purification mounting bracket 23, the setting mode is simple, and the overall structure is simplified.

[0127] It should be noted that the purification channel 22 can form part of the purification air duct 13, and the rest of the purification air duct 13 is formed on the shell 1. Of course, the humidification channel 32 can form part of the humidification air duct 14, and the rest of the humidification air duct 14 is formed on the shell 1. Alternatively, the purification channel 22 can form the complete purification air duct 13, and the humidification channel 32 can form the complete humidification air duct 14. The above embodiments are within the protection scope of the present application.

[0128] The following embodiments are described by only considering that the purification air duct 13 and the humidification air duct 14 are independently controlled to be opened and closed by the switch door mechanism 4. In an embodiment, the purification channel 22 is formed in the purification module 2 and is located on the purification air duct 13. The first gate 21 is arranged in the purification channel 22. The first gate 21 is arranged in the purification module 2, which facilitates the arrangement of the first switch door mechanism 4a on the purification module 2. By opening and closing the first gate 21 in the purification module 2, the purification channel 22 can be opened and closed, and the purification air duct 13 can be opened and closed. In this way, the first switch door mechanism 4a is arranged.

[0129] Specifically, in an embodiment, please refer to Figures 7 to 9 and Figures 12 to 15 The opening of the first gate 21 is arranged towards the side wall of the shell 1.

[0130] The first driving device 42 drives the side opening and closing plate 41 to swing to open or close the first gate 21. A linear driving device can be used in cooperation with a linkage structure. In an embodiment, the purification module 2 includes a purification mounting bracket 23 fixed in the shell 1. The first driving device 42 includes a first driving motor 421 and a gear transmission structure 422. The first driving motor 421 is arranged on the purification mounting bracket 23.

The hinge end of the side opening and closing plate 41 is fixedly installed at the rotation center of the gear plate 4221. The rotational movement of the first driving motor 421 is transmitted to the swing of the gear plate 4221 through the gear transmission structure 422, thereby driving the rotation of the side opening and closing plate 41. The first driving motor 421 facilitates automatic control. The gear transmission structure 422 transmits torque, has good stability, and has a compact structure.

[0131] Further, the gear transmission structure 422 further includes a first driving gear 4222 sleeved on the first output shaft. The first driving gear 4222 is in meshing engagement with the toothed outer surface of the gear plate 4221. Of course, other transmission gears can be arranged between the first driving gear 4222 and the gear plate 4221. The number of transmission gears is not limited. By setting the precise transmission ratio between the first driving gear 4222 and the gear plate 4221, the opening degree of the first gate 21 opened and closed by the side opening and closing plate 41 can be accurately controlled, which has good effect.

[0132] In an embodiment, the purification channel 22 includes a first purification channel segment 221 extending upward and downward and a second purification channel segment 222 laterally communicating with the first purification channel segment 221. The first gate 21 is formed in the second purification channel segment 222. A plurality of second purification channel segments 222 are arranged along the circumference of the shell 1. A plurality of side opening and closing plates 41 are arranged to open or close the corresponding first gates 21. By arranging a plurality of second purification channel segments 222, the air treatment device 100 has a large air intake capacity.
