Description

Technical Field

[0001] The invention relates to the technical field of juicers. Background Art

[0002] An existing juicer includes a cup body, a cutter, a motor seat, a motor, a circuit board and a cover body. The cup body is provided with a motor seat at the top, and an axial hole is opened at the bottom of the motor seat. The motor is placed on the motor seat, and the motor shaft passes through the axial hole and extends into the cup body. The cutter is arranged on the motor shaft in the cup body. The circuit board is placed in the cover body, and the cover body is covered at the upper opening of the cup body. The circuit board is electrically connected to the motor. The juicer of the above structure has the following disadvantages: (1) When turning on the machine, the user presses (turns on) the motor control switch and the motor starts to work. However, if the cover body is not completely covered with the cup body, the motor control switch will still be turned on, and the high-speed rotating cutter is prone to safety hazards. Summary of the invention

[0003] The object of the present invention is to provide a juicer which is safe to use.

[0004] The object of the present invention is achieved in that:

[0005] A juicer, comprising a cup body, a cutter, a motor seat, a motor, a circuit board and a cover body, wherein the upper part of the cup body is provided with a motor seat, the bottom of the motor seat is provided with an axial hole, the motor is placed on the motor seat, the motor shaft passes through the axial hole and extends into the cup body, the cutter is arranged on the motor shaft in the cup body, and the feature is that it also comprises a motor positioning frame, the circuit board is fixed on the motor positioning frame and placed together on the motor seat, the upper part of the motor abuts against the motor positioning frame, the motor positioning frame is also provided with a touch switch component, and the A motor control switch is arranged on the circuit board, and the cover body is arranged on the upper opening of the motor seat, and the trigger switch element is against or close to the motor control switch. In this juicer, a trigger switch element is added to the motor positioning frame so that after the cover body is closed, the motor control switch and the trigger switch element are against each other, so that the normally open motor control switch is closed, the circuit board is powered on, and the motor works. If the cover body is not closed or not completely closed, the trigger switch element fails to trigger the motor control switch to operate. At this time, the circuit board is powered off and the motor does not work, thereby ensuring the safety of users.

[0006] The present invention can also be solved by the following technical measures:

[0007] Furthermore, the touch switch member is a long elastic strip, one end of which is connected to the motor positioning frame body and the other end is a free end, which is against or close to the motor control switch; the long elastic strip has good elasticity and is easy to deform to prevent damage to the motor control switch (such as a micro switch) due to excessive pressure.

[0008] Furthermore, the motor positioning frame is provided with a slot, one end of which extends the long elastic bar, and the other end of the long elastic bar is the free end; this solution is easy to implement, and the long elastic bar has better elasticity.

[0009] Furthermore, a touch column extends downward from the bottom of the free end, and a touch column groove is opened at a corresponding position on the motor seat, and the touch column is against or adjacent to the touch column groove; the touch column is conducive to the positioning of the touch switch component on the motor seat, and enables the touch switch component to touch the motor control switch.

[0010] Furthermore, a waterproof rubber sleeve is additionally provided between the trigger column and the trigger column groove to achieve a waterproof effect.

[0011] Furthermore, a sealing pad is provided at the bottom of the waterproof rubber sleeve, and the sealing pad can further enhance the waterproof effect.

[0012] Furthermore, a positioning groove is provided on the motor positioning frame, and the upper part of the motor is embedded in the positioning groove; the design of the positioning groove enables the motor positioning frame to also have the positioning function of the motor, thereby preventing the motor from generating large noise due to vibration when working.

[0013] Furthermore, a battery is included. The battery is pressed on the motor seat by the cover body, and the battery is electrically connected to the circuit board and the motor.

[0014] Furthermore, a battery is included. The motor positioning frame is provided with a battery clamp, and the battery is clamped in the battery clamp; the battery is fixed on the motor positioning frame, and the battery is electrically connected to the circuit board and the motor.

[0015] Furthermore, it also includes a spring, which is sleeved between the touch switch member and the motor control switch; the spring acts so that after the user closes the cover, the circuit board is pressed down, and the spring has a certain buffering force to prevent the motor control switch on the circuit board from quickly pressing down the touch switch member on the motor positioning frame, which may easily cause damage to the motor control switch; in addition, when the cover is opened or incompletely closed, the spring quickly pops up the circuit board, so that the motor control switch is quickly disconnected, preventing the cover from being opened or incompletely closed, and the motor can still rotate to work, thereby greatly improving the safety of its use.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) This juicer has a trigger switch component added to the motor positioning frame so that when the cover is closed, the motor control switch and the trigger switch component abut against each other, closing the normally open motor control switch, energizing the circuit board, and causing the motor to work. If the cover is not closed or not completely closed, the trigger switch component fails to trigger the motor control switch, and at this time, the circuit board is powered off and the motor does not work, thereby ensuring user safety.

[0018] (2) Furthermore, the trigger switch member is a long elastic strip, which has good elasticity and is easy to deform, so as to prevent the motor control switch (such as a micro switch) from being damaged due to excessive pressure; and a slot is provided on the motor positioning frame, one end of which extends the long elastic strip, and the other end of which is the free end; this solution is easy to implement, and the long elastic strip has better elasticity.

[0019] (3) In addition, a waterproof rubber sleeve is provided between the trigger column and the trigger column groove to achieve a waterproof effect; the sealing gasket can further enhance the waterproof effect.

[0020] (5) More preferably, the invention further comprises a spring, which is sleeved between the touch switch element and the motor control switch. As a result, after the user closes the cover, the circuit board is pressed down, and the spring has a certain buffering force, thereby preventing the motor control switch on the circuit board from quickly pressing down the touch switch element on the motor positioning frame, which may easily cause damage to the motor control switch. Furthermore, when the cover is opened or incompletely closed, the spring quickly pops up the circuit board, so that the motor control switch is quickly disconnected, thereby preventing the cover from being opened or incompletely closed, and the motor can still rotate and work, thereby greatly improving the safety of its use.
