Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a structure that prevents debris from triggering a vacuum cleaner switch. Background Art

[0002] A vacuum cleaner is used to absorb dust from surfaces. When you press the on / off button, it contacts a microswitch, which activates the suction motor via the control panel. The suction motor draws dust into the dust box. When the dust is removed, the return spring releases the on / off button, disengaging the microswitch and stopping the suction motor. If foreign matter touches the on / off button, it triggers the microswitch, keeping the suction motor in operation. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a structure for preventing debris from triggering the switch of a vacuum cleaner in view of the deficiencies in the prior art.

[0004] In order to solve the above technical problems, the present utility model adopts the following technical solutions.

[0005] A structure for preventing debris from triggering a vacuum cleaner switch, comprises a gun-type handle, a vacuum cleaner body, a microswitch, a return spring and a switch button; the vacuum cleaner body comprises a dust cup, a filter cover and a suction fan, the gun-type handle is provided with an air inlet channel connected to the dust cup, a battery and a control board are provided inside the gun-type handle, the microswitch, battery and suction fan are respectively connected to the control board, the gun-type handle comprises an annular handle and a support frame, the vacuum cleaner body is arranged on the support frame, one end of the switch button is rotatably connected to the inner side of the annular handle, and the other end is a freely movable end, one end of the return spring is connected to the inner side of the annular handle, and the other end is connected to the switch button, the microswitch is arranged in the annular handle and close to the switch button, the switch button contacts the microswitch under the action of external force, and a blocking piece is provided inside the annular handle, and the blocking piece is arranged on the lower side of the switch button to prevent debris from touching the switch button.

[0006] A preferred solution is that the support frame includes a front section and a rear section, the air inlet channel is arranged in the front section, and the battery and control board are arranged in the rear section.

[0007] A preferred solution is that a supporting plane is provided at the bottom of the annular handle.

[0008] A preferred solution is that the filter cover is arranged in the dust cup, the suction fan is connected to the dust cup, the suction fan is arranged on the rear side of the support frame, and the dust cup is arranged on the front side of the dust cup support frame.

[0009] The structure provided by the present invention for preventing debris from triggering the vacuum cleaner switch has at least the following beneficial effects: when an external force is applied, the switch button is pressed, causing it to contact the microswitch, and the microswitch, battery, and suction fan form a closed circuit with the control board. The control board controls the suction fan, which then sucks dust into the dust cup. When the external force is removed, the switch button rebounds under the action of the return spring, separating the switch button from the microswitch. The microswitch is now in the off state, and the suction fan does not operate. A baffle is provided on the lower side of the switch button to prevent debris from triggering the switch button, thereby preventing the suction fan from continuously operating due to external debris touching the switch button.
