Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an air purifier and a negative ion emission head self-cleaning structure applied to the air purifier. Background Art

[0002] At present, air purifiers are usually provided with negative ion generators for generating high concentrations of negative ions, which are released into the environment by the release beam at the end of the negative ion emission head, purifying the ambient air and improving the ambient air quality. However, since the release beam is arranged outside the shell, it is very easy to accumulate dust and seriously affect the release effect of negative ions. Therefore, those skilled in the art have designed a cleaning structure to regularly clean the release beam. For example, the Chinese patent with application number 202220911930.2 discloses a self-cleaning negative ion generator, in which the cleaning component includes a driving member and a cleaning member, and the cleaning member is arranged on the side of the release beam. The driving member can drive the cleaning member to sweep across the release beam, and then the release beam of the negative ion releaser is cleaned by the cleaning member. The disadvantage of this cleaning component is that: since the release beam is a brush-like structure composed of a number of conductive wires, first, when the cleaning member sweeps over the release beam for many times, it is easy to cause the release beam to deform, which is not conducive to the efficient release of negative ions; second, when the cleaning member sweeps over the release beam, its contact area with the release beam is small, causing the release beam to be unable to be effectively cleaned. Therefore, it is necessary to make improvements. Summary of the invention

The cleaning member 2 can be driven by the driving member 3 to drive the cleaning head 21 to sweep across the release beam 11.

[0025] like Figure 4 and Figure 5 The cleaning head 21 is a horizontally arranged long rod-shaped structure, and has a plurality of protrusions 22 arranged facing the release beam 11 on its side, and a recess 23 arranged facing the release beam 11 is formed between two adjacent protrusions 22.

[0026] In the above structure, the convex portion 22 and the concave portion 23 of the cleaning head 21 increase the contact area with the release beam 11 , thereby improving the cleaning effect on the release beam 11 .

[0027] like Figure 4 and Figure 5 Furthermore, the concave portion 23 of the present embodiment is an arc-shaped groove structure, and the convex portion 22 is an arc-shaped structure, so as to avoid physical damage to the release beam 11 during the contact process with the release beam 11.
