Description

Power supply conduction device of juicer

Technical Field

The utility model relates to a power switch on device of fruit juice mixer especially indicates that the upper cover does not establish before firm with the container opening cover, and its supply motor moving power can't switch on smoothly promptly, and then the user is unlikely to be because of the mistake touches other switches and the driving motor operation, causes the danger of rubbing sword wound and personnel, switches on the device for the power that possesses dual safety efficiency.

Background

The power starting switch and the rotating speed control switch of the conventional juicer are mostly arranged on an operation panel of the motor base, and the operation panel comprises various rotating speed control switches, power starting switches and the like; when the power starting switch is actuated to drive the motor to start to operate, if the upper cover is not firmly covered with the opening of the container, the defect that the juice is splashed out of the container due to the grinding rotation is easily caused; in addition, the mincing knife rotating at high speed inside the hollow container is dangerous to hurt (for example, a child curiously puts his hand into the container, or a user accidentally injures the mincing knife when adding the material to be minced).

Disclosure of Invention

For overcoming the drawback that the power supply of the conventional juicer is short of necessary safety, the main object of the utility model is to provide a power supply conduction device of the juicer which has dual safety functions and accords with industrial utilization.

The utility model provides a power supply conduction device of a juicer, which consists of a first conductive contact of a motor seat, a second conductive contact and a third conductive contact of a cutter fixing ring, a power line with a fourth conductive contact, a pressing piece and a conduction piece;

wherein,

the first conductive contact and the second conductive contact are jointed when the motor seat is embedded and fixed with the cutter fixing ring; the third conductive contact and the fourth conductive contact are jointed when the cutter fixing ring pressing cutter seat is screwed and positioned with the lower part of the hollow container; the power line is embedded in the wire embedding groove at the outer edge of the handle of the hollow container, the top end of the handle is concavely provided with an embedded groove for positioning the conductive switch, and the outer part of the handle is coated with a cover layer; the pressing piece is embedded and fixed on the bottom surface of the convex edge sheet of the upper cover.

In the power supply conduction device of the juicer, the pressing piece is a permanent magnet, and the conductive switch can be a magnetic reed switch.

The power supply conducting device of the juicer is embedded and wound on the power line on the outer edge of the handle of the hollow container and is directly formed inside the handle.

According to the power supply conduction device of the juicer adopting the technical scheme, the upper cover of the power supply conduction device is not firmly arranged with the opening cover of the container, and before the pressing piece is not jointed with the conduction piece, the power supply loop for driving the motor to operate is in an open circuit state, the grinding knife which is arranged in the hollow container and is linked through the motor to operate is positioned, before the upper cover is accurately arranged with the cover and the power supply loop is not conducted, the danger that personnel are injured due to the rotation of the grinding knife because various switches on the operation panel of the motor seat are touched by mistake is avoided, and the power supply conduction device of the juicer with double safety effects is provided.
