CN203328493U - Juicer capable of preventing cutter from being jammed - Google Patents

Abstract

A juicer capable of preventing a cutter from being jammed comprises a base, a cup body and the cutter, wherein a motor is arranged inside the base, and an output shaft of the motor is connected with a cutter shaft in a transmission mode. The juicer capable of preventing the cutter from being jammed further comprises a connecting rod, wherein one end of the connecting rod fixes the cutter, a cavity where the connecting rod moves axially is formed in the upper end of the cutter shaft, and a reset mechanism enabling the connecting rod to reset is arranged in the cavity. According to the juicer, the cavity where the connecting rod used for fixing the cutter moves axially is formed in the cutter shaft, once the cutter is jammed by vegetable and fruit blocks when cutting vegetables and fruits, the connecting rod of the cutter moves downwards to provide a rotary space for the cutter in the axial direction, the cutter moves downwards, and the jamming problem is resolved. Meanwhile, the reset mechanism is arranged in the cavity, the cutter moves upwards to reset, and the cutter continues cutting vegetables and fruits in a rotating mode under the driving of the motor. Therefore, the juicer of the structure can automatically adjust the axial displacement of the cutter when cutting vegetables and fruits to prevent the cutter from being jammed and prevent the motor from being burned out.

Description

A kind of fruit juice mixer that prevents that cutter is stuck

Technical field

Along with rapid development of economy, the quickening day by day of rhythm of life, people are more and more not free to go to join into sports, the deficiency that amount of exercise is serious, and increasing people's build trend is fat, because obesity easily causes various diseases, seeking under healthy guiding, organic vegetables and fruits become the diet good merchantable brand in health of people life, and by vegetables and fruits squeezing the juice by fruit juice mixer, not only more convenient edible, and improved mouthfeel.

Common fruit juice mixer generally comprises support, motor, tool rest, cutter and cup.Tool rest is provided with cutter shaft, the upper end of cutter shaft directly is connected with cutter, lower end is connected with upper coupling piece, be provided with the lower coupling piece be connected with the motor power output shaft on support, upper coupling piece is connected with lower coupling piece, by motor, provides power drive cutter high-speed rotary to transfer the cutting vegetables and fruits and reaches the purpose of squeezing the juice.But; fruit juice mixer the cutting some hard fruit as processes such as fragrant plant pleasure, pears in; often occur that cutter is stuck; because cutter can't move in the axial direction; no matter how motor rotates also can't make cutter again rotate; make motor stopping if now cut away not in time power supply, also likely cause burning of motor.This kind of shortcoming of fruit juice mixer commonly used, cause people in the process that harder objuct is squeezed the juice, need to be at fruit juice mixer at one's side, once occur that the situation that cutter blocks just closes swap switch at once, then vegetables and fruits in cup are integrated.Therefore, the use inconvenience very of existing fruit juice mixer to people, need to be improved fruit juice mixer, and cutter can be moved in the axial direction, thus cutter automatically adjust, prevent the generation of cutter stuck phenomenon.

The utility model content

The utility model provides a kind of fruit juice mixer that prevents that cutter is stuck, solves the generation of existing fruit juice mixer stuck phenomenon, even makes the technical problem of burn-down of electric motor.

The utility model adopts following technical scheme:

A kind of fruit juice mixer that prevents that cutter is stuck, comprise support, cup and cutter, is provided with a motor in pedestal, and the output shaft of the motor cutter shaft that is in transmission connection, also comprise the connecting rod that an end is fixing by described cutter, and described connecting rod slidably is located on described cutter shaft.

Described cutter shaft upper end is provided with one for the axially movable chamber of described connecting rod, is provided with the resetting-mechanism that connecting rod is resetted in described chamber.

Described resetting-mechanism is preferably spring.

Particularly, described chamber is provided with an opening inserted for connecting rod, also be provided with the guide rail be arranged in parallel with described connecting rod on the sidewall of chamber, described connecting rod middle and lower part cross section is square, the fastener that described connecting rod bottom is provided with a horizontally set and moves up and down along described guide rail.

Described cavity bottom is provided with a described spring be sheathed on the fastener lower link, and wherein, the length of connecting rod of fastener lower end is less than spring length.

Sheathed described spring on the connecting rod on described fastener top, this spring upper end is held on the roof of described chamber.

The sheathed described spring of difference on the connecting rod of described fastener upper and lower part, wherein, the spring top on top is held on the roof of described chamber, and the spring top of bottom is held on the diapire of chamber.

From the above-mentioned description to the utility model structure, compared to the prior art, the utlity model has following advantage: the fruit juice mixer of this structure is provided with an axially movable chamber of connecting rod for fixed cutting tool at cutter shaft, once Tool in Cutting, by the vegetables and fruits block, blocked, the connecting rod of cutter moves down the space of creating in the axial direction rotation for cutter, cutter moves down the problem of blocking that solves, be provided with a resetting-mechanism in chamber simultaneously, cutter moves on again and returns to reset condition, cutter continues the rotary cutting vegetables and fruits under driven by motor, but therefore the fruit juice mixer of this structure in the displacement in the axial direction of when cutting automatic adjusting tool to prevent the generation of its stuck phenomenon, avoid burn-down of electric motor.
