[0002] In recent years, with the improvement of people's quality of life, people have become more aware of their health and demand higher air quality. This has led to a growing demand for filtration in air handling devices such as fans. Generally, filters are installed in the air flow path of fans and other air handling devices to pre-emptively remove impurities such as dust and lint, delivering clean, healthy air, which is highly sought after by consumers.

[0003] However, if the filter is not replaced in time, due to long-term use of the filter, the dust, lint and other impurities attached to the filter will reduce the air permeability of the fan and other air handling devices, thereby affecting the air volume and causing the pressure of the input air volume to increase. If the fan and other air handling devices operate in this state for a long time, the power of the motor and mainboard will increase, and continuous operation will damage the fan and other air handling devices.

[0075] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0076] The following combination Figures 1 to 13 , describing the embodiments of the present utility model.

[0077] According to an embodiment of the present utility model, an air treatment device is provided, including an air duct assembly 1, a filter 2, a cleaning member 3, a dust collecting assembly and a first power mechanism 5; the filter 2 is rotatably connected to the air duct assembly 1 and is located on the flow path of the air duct assembly 1; the cleaning member 3 is connected to the air duct assembly 1 and is in contact with the filter 2; the dust collecting assembly is arranged on the air duct assembly 1, for collecting dirt on the filter 2 cleaned by the cleaning member 3; the first power mechanism 5 includes a first power output end 51, which is connected to the filter 2.

[0078] The filter 2 is arranged on the circulation path of the air duct component 1, and can filter the air circulated by the air treatment device. It can filter out dust, lint and other impurities in the air in advance when blowing, and send out clean and healthy air; when cleaning the filter 2, the filter 2 rotates under the drive of the first power mechanism 5 to ensure that every part of the filter 2 can contact and rub with the cleaning member 3 to comprehensively clean the dust, lint and other impurities attached to the filter 2; the dust collecting component can collect the dirt dropped by the cleaning member 3 during the cleaning process of the filter 2, thereby achieving the purpose of cleaning the filter 2; ensuring that the filter 2 will not be attached with dust, lint and other impurities when used for a long time, ensuring the air permeability of air treatment devices such as fans, ensuring the air volume, avoiding damage to air treatment devices such as fans, and extending the service life of air treatment devices such as fans.

[0079] In the filter 2 cleaning device of the related art, a drive module is provided to drive the cleaning member 3 to move along the surface of the filter 2 to clean the filter 2. In order to collect the dirt that falls off during the cleaning of the filter 2 by the cleaning member 3, the dust collection assembly needs to move along with the cleaning member 3. In order to ensure the smooth movement of the cleaning member 3 and the dust collection assembly, a large space needs to be reserved for the cleaning member 3 and the dust collection assembly in the air conditioner, and the overall cleaning device is relatively complex. In this embodiment, since the filter 2 is connected to the first power output end 51 of the first power mechanism 5, the filter 2 can rotate and rub relative to the cleaning member 3 under the drive of the first power output end 51, ensuring that every position of the filter 2 can be cleaned by the cleaning member 3. The cleaning member 3 does not need to move along the surface of the filter 2 to effectively clean the filter 2, and the dust collection assembly does not need to move to collect the dirt that falls off during cleaning. The space occupied by the cleaning member 3 and the dust collection assembly in the air treatment device is significantly reduced, and the structure is relatively simple.

[0080] In one embodiment, the cleaning member 3 is rotatably connected to the air duct assembly 1 , and the rotation axis of the cleaning member 3 is perpendicular to the rotation axis of the filter 2 .

[0081] The rotation axis of the cleaning member 3 is arranged perpendicular to the rotation axis of the filter 2, so that the position of the cleaning member 3 relative to the air duct assembly 1 does not change, and it only rotates in the original position, avoiding that the cleaning member 3 takes up too much space, and the dust collecting assembly can collect the dirt dropped during the cleaning process without moving; and the cleaning member 3 is rotatably connected to the air duct assembly 1, and can also achieve rapid friction between the surface of the filter 2 and the cleaning member 3, thereby obtaining a better cleaning effect.

[0082] In a specific embodiment, the air treatment device can be provided with a separate drive mechanism for the cleaning member 3, so that the driving mechanism drives the cleaning member 3 to rotate, which can facilitate adjustment of both the rotation direction and the rotation speed of the cleaning member 3, so as to facilitate cleaning of filter screens 2 with different degrees of dirtiness. When the degree of dirtiness of the filter screen 2 is high, the driving mechanism can be set to adjust the rotation directions of the cleaning member 3 and the filter screen 2 to be opposite to each other, thereby increasing the friction between the cleaning member 3 and the filter screen 2 and improving the friction cleaning effect. When the degree of dirtiness of the filter screen 2 is low, the driving mechanism can be set to adjust the rotation directions of the cleaning member 3 and the filter screen 2 to be in the same direction, thereby reducing the friction between the cleaning member 3 and the filter screen 2 and reducing the friction cleaning effect. Specifically, when the rotation directions of the cleaning member 3 and the filter screen 2 are adjusted to be in the same direction, the cleaning member 3 and the filter screen 2 rotate at different speeds. Alternatively, when the degree of dirtiness of the filter screen 2 is low, the driving mechanism is not activated, and the cleaning member 3 rotates with the filter screen 2, which can also achieve a good cleaning effect. In this embodiment, the rotation directions of the cleaning member 3 and the filter screen 2 are opposite to each other, which means that the cleaning member 3 and the filter screen 2 move in opposite directions at the position where they contact each other. The rotation directions of the cleaning member 3 and the filter screen 2 are the same, which means that the cleaning member 3 and the filter screen 2 move in the same direction at the position where they contact each other.

[0083] Specifically, in another embodiment, the air treatment device does not provide a rotational driving force for the cleaning member 3. During the friction with the filter 2, the cleaning member 3 rotates along with the filter 2 driven by the filter 2, thereby reducing friction and reducing damage to the filter 2 and the cleaning member 3.

[0084] Specifically, in another embodiment, the air treatment device further includes a transmission assembly 6 , and the filter 2 and the cleaning element 3 are both connected to the first power output end 51 via the transmission assembly 6 .

[0085] The setting of the transmission assembly 6 can not only transmit the power of the first power output end 51 of the first power mechanism 5 to the filter 2 to drive the filter 2 to rotate, but also transmit the power of the first power output end 51 of the first power mechanism 5 to the cleaning member 3 to drive the cleaning member 3 to rotate, thereby simplifying the overall structure and reducing the occupied space.

[0090] In one embodiment, the filter screen 2 is annular, and the first driven gear 62 is connected to the inner ring of the filter screen 2 .

[0091] The filter screen 2 is annular, which facilitates connection with the first driven gear 62 and also facilitates engagement between the annular first driven gear 62 and the spur gear portion 611 . The filter screen 2 has a simple structure and occupies less space.

[0093] By setting the limiting protrusion 621 and the limiting groove 21, it can be ensured that the filter screen 2 and the first driven gear 62 are mutually limited in the circumferential direction, so that the filter screen 2 can rotate following the first driven gear 62, and avoid the filter screen 2 and the first driven gear 62 from being misaligned or moving relative to each other in the circumferential direction.

[0094] In a specific embodiment, the inner ring of the filter screen 2 is provided with a limiting groove 21, and the outer periphery of the first driven gear 62 is provided with a limiting protrusion 621, so as to ensure the thickness and strength of the first driven gear 62 in the radial direction.

[0095] Specifically, in another embodiment, the inner ring of the filter screen 2 is provided with a limiting protrusion 621 , and the outer periphery of the first driven gear 62 is provided with a limiting groove 21 .

[0096] Furthermore, the number of the limiting protrusions 621 and the limiting grooves 21 are the same, with at least two being provided, and are distributed at intervals along the circumferential direction, preferably evenly distributed.

[0097] In a preferred embodiment, four limiting protrusions 621 and four limiting grooves 21 are provided, and the four limiting protrusions 621 and the four limiting grooves 21 are evenly distributed along the circumferential direction.

[0098] Furthermore, the limiting groove 21 is a rectangular groove, and the shape of the limiting protrusion 621 matches the shape of the limiting groove 21.

The filter 2 is rotatably connected to the duct body 11, and the cleaning element 3 is rotatably connected to the rear screen 12.
