Embodiment 1

[0039] Such as Figures 1 to 11 A safety switch waterproof juice extractor shown includes a base 4, a motor, a safety switch and a stirring cup 5, the motor is located in the base 4, the bottom of the stirring cup 5 is provided with a socket 50, and the base 4 is provided with a socket 50 Cooperating slot 40, slot 40 is provided with groove 41, and safety switch is positioned at groove 41, and plug sleeve 50 is provided with the bump 51 that can promote safety switch when pressing down, and safety switch is connected with motor.

[0040] The position of the safety switch is in the groove 41 of the slot 40 of the base 4, the safety switch is not easy to be squeezed by fingers or sticks, and the staff avoids the threat caused by the opening of the motor, which greatly improves the safety.

[0041] Secondly, because the safety switch is located in the groove 41, there is and only when the protrusion 51 on the sleeve 50 of the stirring cup 5 is pressed into the groove 41 on the sl...

Embodiment 2

[0060] Such as Figure 12 and Figure 13 As shown, the difference between the present embodiment and the first embodiment is that the second contact part 110 is a metal ring with a slope, the slope of the metal ring faces the rear end of the movable contact 31, the convex part 310 is in the shape of a ring, and the movable contact 30 is a circular platform. shape.

[0061] The corresponding effects are as follows: firstly, the annular inclined surface of the metal ring forms a tapered surface, and the second contact portion 110 can increase the contact area with the convex portion 310, effectively avoiding poor contact and improving safety.

[0062] Secondly, the conical surface of the metal ring cooperates with the annular convex portion 310 to make the convex portion 310 concentric with the metal ring to ensure the concentricity of the two, so that the top of the contact can be accurately aligned with the arc-shaped contact portion of the first contact portion 100 1001, to...

Abstract

The invention discloses a juicer with a waterproof safety switch. The juicer is characterized in that the safety switch inside the juicer comprises a shell, a switch knob, an automatic isolation door structure and a main spring used for the switch knob; the switch knob comprises a movable contact; a convex part is arranged at the rear end of the movable contact; the shell is provided with a first cavity, a second cavity, a first connection terminal and a second connection terminal; the automatic isolation door structure comprises a drive-by-wire, a pulley block and an opening and closing door with a reset mechanism; when the switch knob is pressed, opening and closing of the opening and closing door can be controlled via the drive-by-wire and the pulley block; when the opening and closing door is tightly closed under the action of the reset mechanism, the first connection terminal in the first cavity can be closed to prevent water vapor from entering the first cavity and the first and second connection terminals are in a complete disconnect state; therefore the safety switch is waterproof, is not easy to age under the effect of damp and has high safety performance, and the service life of the safety switch is prolonged.

Description

technical field [0001] The invention relates to a juice extractor, which is a waterproof juice extractor with a safety switch. Background technique [0002] A juicer is a machine that can quickly squeeze fruits and vegetables into vegetable juice. [0003] The existing juice extractor includes a base, a motor and a stirring cup, the motor is arranged in the base, the opening of the base cooperates with the base of the stirring cup, when the stirring cup is placed at the opening of the base, a safety switch is arranged at the opening of the base, When the stirring cup is pressed down, the safety switch is turned on, and the motor can drive the stirring device in the stirring cup to crush the fruits and vegetables. [0004] However, when the juicer is in use, it is often necessary to add drinking water to the mixing cup for neutralization, so the safety switch is prone to water ingress during operation, causing the safety switch to fail, and there are hidden dangers. Conten...
