Embodiment 1

[0049] Such as figure 1 with figure 2 As shown, a filter element cleaning device 1 provided by an embodiment of the present invention includes a suction head assembly 12, a sliding mechanism 13, and a negative pressure generator 14. The suction head assembly 12 is connected to the negative pressure generator 14, and the sliding mechanism 13 drives the suction head assembly. 12 moves along the surface of the filter core 20 to absorb the attachments on the surface of the filter core 20.

[0050] Further, the sliding mechanism 13 includes a slide rail, a pulley 21 and a motor assembly, the pulley 21 is arranged in the slide rail, and the motor assembly drives the suction head assembly 22 to move along the surface of the filter element 20 through the slide rail and the pulley 21 .

[0051] Wherein, the slide rail includes a slide rail body, a starting end located at the starting point of the slide rail body, and a terminal end located at the end position of the slide rail body. Th...

Embodiment 2

[0059] Such as image 3 As shown, an air purifier 32 provided by an embodiment of the present invention includes a housing 33, a filter element 20 disposed in the housing 33, and the filter element cleaning device 1 provided in the first embodiment above. The filter element cleaning device 1 is used for suction Remove the attachments on the surface of the filter element 20. The air cleaner 32 also includes an air inlet opened on the surface of the casing 33 of the air cleaner 32 , and an air duct between the air inlet and the filter element 20 .

[0060] As a preferred solution, the position of the filter element cleaning device 1 is set according to the position between the air duct and the filter element 20, and the installation position of the filter element cleaning device 1 is located at a position where the air duct will not be blocked, wherein the filter element cleaning device 1 can be arranged at The front, top or bottom of the side to be cleaned in the filter elemen...

Embodiment 3

[0070] Such as Figure 5 As shown, the embodiment of the present invention provides a method for cleaning the filter element of an air purifier, which is a method for cleaning the attachments on the surface of the filter element through a filter element cleaning device placed inside the air purifier, including the following steps:

[0071] S1. Detect the thickness of the attachment on the surface of the filter element through the attachment thickness detection mechanism. When the thickness of the attachment exceeds the set threshold, start the negative pressure generator and the sliding mechanism, and / or send a prompt message for cleaning the attachment.

[0072] The general control part of the air purifier sends a detection command to the laser generator, and the laser generator controls the laser probe to emit light for detecting the thickness of the attachment under the drive of the detection command. After the light reaches the filter element, it is reflected back to the la...

Abstract

The invention provides an air purifier and its filter element cleaning device and method, and relates to the technical field of air purifiers, wherein, a filter element cleaning device includes a suction head assembly, a sliding mechanism and a negative pressure generator, and the suction head assembly is connected to a negative pressure generator. A pressure generator, the sliding mechanism drives the suction head assembly to move along the surface of the filter element, and absorbs the attachments on the surface of the filter element; an air purifier, including a shell, a filter element installed in the shell, and a filter element cleaning device, the filter element cleaning device is used for suction Remove the attachments on the surface of the filter element. The technical problem of inconvenient cleaning of filter element attachments existing in the air purifier in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to an air purifier and its filter element cleaning device and method. Background technique [0002] The air purifier mainly uses its internal suction motor to suck the external air into the body, and then filters the inhaled air through the built-in filter element, so that harmful substances such as dust and particulate matter in the air are adsorbed on the filter element. Surface, to ensure that the discharged air will no longer contain dust, particles and other harmful substances, in order to achieve the purpose of air purification. [0003] As the density and thickness of the substances adsorbed on the front of the filter element continue to accumulate, the filtration performance of the filter element will also weaken. In order to avoid the above situation, it is necessary to clean the filter element in time. [0004] At present, the cleaning of the filter element in the e...
