Further, referring to fig. 5, in the present embodiment, the body assembly 100 further includes a control mechanism 5 disposed on the handle 1. The control mechanism 5 is coupled with a power supply (such as the battery pack 3 and/or an external power supply) and electric devices of the cleaning tool through a lead 6, and receives mechanical operation of a user to switch the state of the user, so that the working state of the cleaning tool is controlled.
Referring to fig. 6, specifically, the control mechanism 5 includes a control panel 51, a fixing base 52, a switch 53, and a push button 54.
The control board 51 is located in the accommodating cavity and is fixedly assembled to the housing 120, and includes a board body 510, a plurality of electronic components 511 arranged on the board body 510, and pin contacts 512. The board body 510 includes a main surface 5101 and a back surface 5102 which are oppositely disposed, and the main surface 5101 and the back surface 5102 are specifically two surfaces of the board body 510 having a large surface area; several electronic components 511 may be provided that are all different, all the same, or partially the same. In this embodiment, several electronic components 511 are disposed on main surface 5101, but in other embodiments, several electronic components 511 may also be disposed on back surface 5102.
The switch 53 includes a switch body 531, a pin 533 fixedly disposed on the switch body 531, and a movable member 532 movably disposed on the switch body 531. The number of the pins 533 is at least two, the pins 533 are corresponding to and matched with the pin contacts 512 one by one, and the pins 533 are electrically connected to the pin contacts 512; in this embodiment, pin contact 512 is configured as a receptacle into which pin 533 may be inserted and make an electrical contact connection.
The push button 54 is coupled to the movable member 532, and the push button 54 can receive a mechanical operation of a user, that is, the user can directly contact the push button 54 and operate the push button 54. When mechanical operation of a user is received, the push button 54 drives the movable member 532 to move, so as to switch the state of the switch 53, and further switch the working state of the cleaning tool.
The fixing seat 52 is assembled and connected with the plate body 510 through the mounting structure and assembled and connected with the switch body 531 through the fixing structure, thus, through the arrangement of the fixing seat 52, only the pin 533 is not used as a contact point between the switch 53 and the control plate 51, the contact point between the fixing seat 52 and the control plate 51 is increased, in the process of driving the movable piece 532 to move by the push button 54, the stress of the pin 533 is reduced or even not stressed due to the sharing of the fixing seat 52, the probability of damage to the switch 53 caused by bending or dislocation of the pin 533 is reduced, the structural stability of the switch 53 is improved, compared with the prior art, the auxiliary control plate and the lead do not need to be additionally arranged, and the limitation on the structural layout is low.
Wherein the push button 54 moves synchronously in the same direction as the movable member 532. Specifically, the movable member 532 reciprocates in the direction t (see arrow mark in fig. 6) relative to the switch body 531, and likewise, the push button 54 reciprocates in the direction t relative to the switch body 531.
In the present embodiment, the moving direction (i.e., direction t) of movable member 532/push button 54 is not parallel to main surface 5101 and is at an acute angle, and the movement of movable member 532/push button 54 has a vertical component perpendicular to main surface 5101 and a parallel component parallel to main surface 5101. Specifically, with reference to fig. 3-7, major surface 5101 is parallel to extension axis C and the left-right direction; the moving direction (i.e., direction t) of the movable member 532/push button 54 is parallel to the operation panel surface P and perpendicular to the left-right direction, so that the moving direction (i.e., direction t) of the movable member 532/push button 54 also has an acute angle β with the main surface 5101. In this case, by providing the fixing base 52, the protection of the pin 533 is further improved compared to the prior art, and the structural stability of the switch 53 is enhanced. Of course, in other embodiments, the moving direction (i.e. direction t) of movable member 532/push button 54 may also be parallel to main surface 5101, which corresponds to the specific embodiment with the vertical component of 0, and the technical solution of the present application is also applicable.
When the push button 54 moves the movable member 532, the mounting structure can prevent the fixed seat 52 from moving relative to the control board 51 along the direction of the parallel component, and the fixed structure can prevent the switch body 531 from moving relative to the fixed seat 52 along the direction of the parallel component. Thus, when the push button 54 moves, the switch body 531 can be prevented from sliding along the direction of the parallel component with respect to the control board 51, so as to further avoid the damage of the switch 53 caused by the bending or dislocation of the pins 533, and improve the structural stability of the switch 53.
Next, the mounting structure of the present embodiment will be described in detail with reference to fig. 5 to 7.
Specifically, the mounting structure includes a fixing clip 71 disposed on the fixing seat 52, and the fixing clip 71 includes a barb 711; when the fixing base 52 is assembled with the board body 510, the end of the fixing clip 71 extends from the main surface 5101 side to the back surface 5102 side beyond the board body 510, and the barb 711 contacts with the back surface 5102 to prevent the fixing base 52 from being vertically detached from the control board 51. Thus, the fixing seat 52 can be assembled and connected to the board body 510 through the fixing clip 71 on the one hand, and the fixing seat 52 can be prevented from being accidentally detached from the control board 51 through the abutting contact of the barb 711 and the back surface 5102 on the other hand.

Moreover, the distance between the bottom surface 5201 of the fixing seat 52 and the barb 711 is just equal to the thickness of the plate body 510; when the holder 52 is assembled to the board body 510, the bottom surface 5201 of the holder 52 contacts the main surface 5101, so that the holder 52 can be prevented from approaching the control board 51 vertically further.

The convex column 73 is in a frustum shape; when the fixing base 52 is assembled and connected to the board body 510, the protruding pillar 73 is inserted into the concave hole 74 in an interference manner, so as to prevent the fixing base 52 from approaching the control board 51 further vertically. Specifically, the protruding pillar 73 is in a truncated cone shape with a gradually increasing diameter, and extends away from the fixing base 52, but in other embodiments, the protruding pillar 73 may also be in a truncated pyramid shape.
