Fig. 1 shows a schematic structural diagram of an impurity cleaning apparatus according to an embodiment of the present application.

Referring to fig. 1, the embodiment of the present application provides an impurity cleaning apparatus, which includes a bracket 1, an air extractor 2, and a cleaning assembly 3.

The holder 1 is for mounting to a target object, and the holder 1 has a first accommodation chamber 11 and a first opening 12 communicating with the first accommodation chamber 11. The target object may be a cabinet. Of course, other devices to be dedusted are also possible.

The air extraction device 2 comprises an air extraction opening 21 and an air outlet 22, the air extraction opening 21 is communicated with the first accommodating cavity 11 through the first opening 12, and the air extraction opening 21 is further provided with a filter bag 23 (see figure 4 in detail). Optionally, the air extraction device 2 is an air extractor. Optionally, the air extraction device 2 further comprises a dust container (not shown in the figures) connected to the extraction opening 21 and in which the filter bag 23 is housed. The filter bag 23 can be a net structure, fine particle impurities such as dust in the air pumped by the air pumping device 2 can enter the dust collector through the filter bag 23, and larger particle impurities are left in the filter bag 23, so as to prevent the impurities from blocking the pumping opening 21 and affecting the pumping function of the air pumping device 2.

The cleaning assembly 3 is connected with the support 1, the cleaning assembly 3 comprises a connecting rod 31, the connecting rod 31 is hollow inside and is communicated with the first accommodating cavity 11, a plurality of through holes (not shown in the figure) are formed in the outer wall of the connecting rod 31, the air extracting device 2 extracts air from the inside of the target object through the through holes, and impurities in the air are collected in the filter bag 23. The connecting rod 31 may be a circular rod with a hollow inside or a rod member of other shape, such as a square rod. Because the connecting rod 31 is provided with a plurality of through holes, when the air extracting device 2 starts to extract air, negative pressure can be formed on the peripheral side of the connecting rod 31, impurities such as dust in the target object can be absorbed into the first accommodating cavity 11 of the bracket 1 through the through holes by the negative pressure, and then the impurities are absorbed into the air extracting opening 21 through the first opening 12, and the impurities with larger particles in the air are filtered out through the filter bag 23.
