Description

Elastic key structure of handheld dust collector

Technical Field

The utility model relates to a dust catcher, especially an elastic button structure of hand-held type dust catcher.

Background

The button of the hand-held cleaner is generally arranged on the shell, and the button is pressed to be abutted against the switch on the control circuit board so as to realize the electric connection of the internal electric elements. However, in the existing key structure, if the key adopts a rubber structure, the installation can be realized directly by the pressing clamp of the shell and the control circuit board, but the problem of easy falling exists; or a layer of elastic cushion is arranged between the plastic key and the control circuit board to realize the support, and even the plastic key is additionally fixed with the circuit board, so the cost is relatively increased.

In order to overcome the defects of the prior art, the utility model provides an elastic button structure of a handheld dust collector.

The utility model provides a technical scheme that its technical problem adopted is:

an elastic key structure of a handheld dust collector comprises a dust collector shell, wherein the shell is provided with a through hole, a plastic key for controlling an internal circuit board to be switched on and switched off is embedded in the through hole, the plastic key comprises a main body matched with the through hole in shape, and a plurality of long arm parts are arranged on the periphery of the main body; the long arm part extends along the edge of the main body, and the tail end of the long arm part is provided with a mounting part fixedly connected with the inner wall of the shell.

Two long arm parts are respectively arranged at two ends of the main body, and the two long arm parts at the same end are respectively arranged along the edges of the left side and the right side of the main body in an extending mode.

The installation parts at the tail ends of the long arm parts are uniformly distributed relative to the periphery of the main body.

The mounting part is a clamping hole, and a convex column penetrating through the mounting part is arranged on the inner wall of the shell; the convex column is higher than the mounting part after being assembled, and the convex part A of the convex column is fixedly connected with the convex column A in a flattening or melting mode.

The shell includes the skeleton inner shell and decorates the shell, inside circuit board switch is located the skeleton inner shell, the installation of plastics button is fixed on decorating the shell inner wall.

The utility model has the advantages that: the plastic key has good elasticity and good pressing hand feeling by arranging the long arm part with the tail end serving as the mounting part on the edge of the key body; and long arm portion extends along button main part edge and sets up, and the inner space that occupies the dust catcher is little, and its deformation mainly is in the direction of luffing motion simultaneously, and the tensile requirement to long arm portion is few, and deformability is stronger, and the structure is more compact, assembles simple, with low costs.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is a schematic view of a hand-held vacuum cleaner according to the present invention;

FIG. 2 is an assembly view of the hand-held cleaner of the present invention;

fig. 3 is a schematic structural diagram of the present invention;

fig. 4 is an assembly schematic of the present invention.

Detailed Description

Referring to fig. 1 to 4, an elastic button structure of a handheld vacuum cleaner comprises a vacuum cleaner housing 1, wherein the housing 1 is provided with a through hole 11, and a plastic button 3 for controlling an internal circuit board switch 2 is embedded in the through hole 11.

The plastic key 3 comprises a main body 31 matched with the through hole 11 in shape, and a plurality of long arm parts 32 are arranged on the periphery of the main body 31; the long arm 32 extends along the edge of the main body 31, and the end of the long arm is provided with a mounting part 33 fixedly connected with the inner wall of the shell 1.

The utility model arranges the long arm part 32 with the end being the mounting part 33 at the edge of the key main body 31, so that the plastic key 3 has good elasticity and good pressing hand feeling; and long arm portion 32 extends along button main part 31 edge and sets up, and the inner space that occupies the dust catcher is little, and the structure is compacter, and its deformation mainly is in the direction of luffing motion simultaneously, and the tensile requirement to long arm portion is few, and deformability is stronger, assembles simple, with low costs.

Preferably, two long arm portions 32 are respectively disposed at two ends of the main body 31, the two long arm portions 32 at the same end are respectively arranged along the left and right side edges of the main body 31 in an extending manner, the two long arm portions are arranged in a symmetrical manner, and the mounting portions 33 at the ends of the long arm portions 32 are uniformly arranged relative to the periphery of the main body 31, so that when the plastic key 3 is pressed, the acting force transmitted to each long arm portion 32 is uniform, the elastic deformation of each long arm portion 32 is the same, the feedback to the key main body 31 is the same, and the pressing feeling is better.
