Specifically, the washing machine of the invention comprises a box body, a tray arranged at the top of the box body and a base arranged at the bottom of the box body, the vibration switch device of the invention can be arranged on the box body, the tray or the base, of course, the vibration switch device can also be arranged on other structures of the washing machine, and a person skilled in the art can flexibly set the actual installation position of the vibration switch device in practical application as long as the on-off of the washing machine can be sensitively and accurately controlled through the vibration switch device. Of course, the washing machine may be a drum washing machine, a pulsator washing machine or other washing machines, and such changes in application types of the washing machine do not limit the scope of the present invention.
Specifically, the washing machine of the present invention includes a control circuit, and the vibration switch device of the present invention includes a collision body and an elastic member connected to the control circuit, and the elastic member is maintained in a closed state by an elastic force in a natural state to turn on the control circuit; when the vibration amplitude of the washing machine exceeds a set threshold, the colliding body collides with the elastic member to expand it and thus the control circuit is disconnected. In summary, the vibration amplitude of the washing machine can be directly fed back by setting the threshold value, and when the vibration amplitude is higher than the set threshold value, the collision body can be greatly deflected and collide with the elastic component to disconnect the control loop, so that the washing machine stops running. It should be noted that the natural state of the present invention refers to a state in which the washing machine is not operated and a state in which the vibration amplitude does not exceed a set threshold, and in this state, the collision body does not touch the elastic component due to the small vibration amplitude of the washing machine, that is, the normal operation of the washing machine is not affected. In addition, it should be noted that the control circuit may be a control system of the washing machine or a control circuit in the control system of the washing machine, and in short, a person skilled in the art can flexibly set the control circuit as long as the on/off of the washing machine can be directly controlled by controlling the on/off of the control circuit.
