It will be appreciated that the devices are versatile, irrespective of their orientation in space.
Example 1
As shown in fig. 3, the embodiment of the application provides a dust cup bottom cover, which is generally used for the bottom of a dust cup, when part of dust in the dust cup needs to be cleaned, the dust cup bottom cover 1 is opened, and the dust in the dust cup can be cleaned out from the opening. The dust cup bottom cover 1 is provided with a bottom cover air channel 2 penetrating through the dust cup bottom cover 1, and considering that the main body of the existing handheld dust collector or portable dust collector adopts a design similar to a revolving body, the air inlet is generally coincident with the axis, and a separate bent air channel is arranged in the dust collector to bypass the dust cup bottom cover 1, the bottom cover air channel 2 penetrating through the dust cup bottom cover 1 can avoid excessive suction loss by shortening the air channel, and the larger suction force of the dust collector is ensured on the premise of not obviously reducing the volume of the dust cup; because the bottom cover air channel 2 passes through the dust cup bottom cover 1, the dust cup can be arranged more compactly, and the miniaturization or integration design of the dust collector is facilitated. The side edge of the dust cup bottom cover 1 is provided with a hinge part 3 and at least 1 clamping part 4, the hinge part 3 is used for being hinged with the dust cup body 6, so that the dust cup bottom cover 1 can be opened or closed, and the clamping part 4 is used for forming a locking structure with a pressing buckle on the dust cup body 6, so that the dust cup bottom cover 1 can still be kept in a closed state under the condition of receiving certain external force.

Illustratively, when the main body of the dust cup bottom cover 1 is circularly arranged, the position where the hinge part 3 is arranged and the position where the overlap positioning part 5 is arranged are circumferentially symmetrical about the axis of the dust cup bottom cover 1, i.e., the center of the circumference. This design can be that overlap joint location portion 5 keep away from hinge portion 3 as far as possible, because dust cup bottom 1 needs to rotate around hinge portion 3, if the two are too close to, overlap joint location portion 5 can influence the rotatory angle of dust cup bottom 1 around hinge portion 3, and then restricts the opening angle of dust cup bottom 1, is unfavorable for the inside dust of clearance dust cup.

In the embodiment of the application, the clamping part 4 is used for forming a pressing lock with a pressing buckle on the dust cup body 6 to lock the dust cup bottom cover 1 in a closed state.
Specifically, as shown in fig. 3, 1 clamping part 4 is provided, and the positions of the clamping parts 4 and the hinge part 3 are symmetrical with respect to the axis of the dust cup bottom cover 1, and the clamping parts 4 are provided at positions far from the hinge part 3, so that the dust cup bottom cover 1 can be stably locked.
Or, the clamping parts 4 are provided with at least 2, all the clamping parts 4 and the hinge parts 3 are uniformly distributed on the side edges of the dust cup bottom cover 1, so that the dust cup bottom cover 1 can be firmly locked everywhere, the acting force born by each clamping part 4 during locking is approximately equal, the fatigue damage of one clamping part 4 relative to other clamping parts 4 is avoided as much as possible, and all the clamping parts 4 can be independently unlocked or locked and/or simultaneously unlocked or locked according to actual needs. For example, 2 clamping portions 4 are provided, the circumferential angles corresponding to the clamping portions 4 and the circumferential angles corresponding to the clamping portions 4 and the hinge portion 3 are 120 °, 2 pressing buckles are provided in one-to-one correspondence with the clamping portions 4, and two pressing locks are simultaneously controlled to be unlocked or locked through one key.

S4, small particle dust and/or foreign matters in the second dust collecting space 14 directly enter the first dust collecting space 10;
s5, small particle dust and/or foreign matters entering the first dust collecting space 10 are separated from the first dust collecting space 10 from the bottom of the dust cup body 6 together with large particle dust and/or foreign matters of the first dust collecting space 10.
In order to ensure that the first dust collecting space 10 and the second dust collecting space 14 are independent of each other, it is necessary to detach the filter assembly, or to take out the second dust collecting space 14, or to provide a separate cleaning channel for the second dust collecting space 14, as is the case in the prior art. The method of the embodiment of the application does not need to disassemble the dust cup, and does not need to independently set an independent cleaning channel for the second dust collecting space 14, so that the whole process is simple to operate, the cleaning steps of the dust cup are simplified, the abrasion of each part in the dust cup caused by repeated installation and disassembly is relieved, and the possibility of bad dust collection effect of the dust collector and the like caused by the fact that the dust collection is not in place can be reduced.
The present application is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present application are intended to be included in the scope of the present application.
