Enough drive the pull rod reciprocating, the current detection module and position switch are electrically connected with the control panel, described
Pull rod can trigger the position switch, and the current detection module is able to detect the load variation of the motor, the control
Plate can control the working condition of the motor according to the signal of the current detection module and position switch.
It in a preferred embodiment, further include having screw rod, the screw rod is connect with the pull rod screw, the electricity
Machine is able to drive the screw rod rotation.
In a preferred embodiment, the fixing end of the motor is connect with the housing into rotation, and the pull rod is straight
It connects and is rotatablely connected with the briquetting.
In a preferred embodiment, the position switch is travel switch or close switch.
In a preferred embodiment, the control panel includes the driving electricity for controlling chip and driving the motor
Road, the control chip are electrically connected with driving circuit, and the input terminal of the current detection module is electrically connected with driving circuit, described
The output end of current detection module is electrically connected with the control chip.
A kind of kitchen appliance includes above-mentioned locking device, further includes having cup body and cup lid, and the cup lid and cup body turn
Dynamic connection, the relatively described cup body of the shell are fixed, and the briquetting can be supported with the cup lid or cup body.
A kind of application method of kitchen appliance, includes the following steps,
10 motor of S is opened, and motor drives pull rod from initial position setting in motion；
For S20 before pull rod moves to first position point, current detection module detects the running current of motor, position
Switch is in first state；
S30 pull rod moves to first position point, at this point, position switch is in the second state, briquetting is supported with cup lid, electric current
Detection module detects that the locked rotor current of motor, control panel control motor stop working, pull rod stop motion；Alternatively, briquetting is not
