Description

Power mechanism for juice extractor

Technical Field

The utility model relates to an electric appliance field, especially power unit technique for juice extractor.

Background

As disclosed in patent CN200910038012.2, the technology is to use an up-down driving mechanism to drive a rotary protrusion head to move towards a cap with a notch, so as to overcome the disadvantages of manual capping, however, the up-down driving mechanism technology adopted in the reference 1 is to move the whole driving power mechanism up and down, because the structure of the driving protrusion head to rotate and the up-down driving mechanism is complex and bulky, it needs to occupy a large moving space when moving up and down, resulting in a large volume of the whole orange machine, which is not only costly to manufacture, but also inconvenient to carry and use, and because the whole driving power mechanism with heavy weight needs to be driven to move up and down, a large amount of electric energy needs to be consumed, and at the same time, a large electric power is needed, and in addition, after the external thread of the rotating shaft is separated from the internal thread, the rotating shaft cannot obtain the support of the internal thread, when the juicing head is used for juicing, the stress is uneven, the uneven stress easily causes the swinging of the juicing head, the swinging rotating shaft can influence the transmission smoothness of the speed change mechanism, the juicing work is influenced, in addition, the swinging rotating shaft can easily cause damage to the internal thread, the swinging rotating shaft can also enable the external thread to be difficult to re-screw into the internal thread, in the prior art, after the external thread of the rotating shaft is separated from the internal thread, the rotating shaft is supported from bottom to top by utilizing a spring, and along with the upward movement of the rotating shaft, the elastic force of the spring is released, the force applied to the rotating shaft by the spring can be weakened, and the perfect juicing is influenced.

Disclosure of Invention

The invention aims to provide a power mechanism for a juice extractor, which has no moving space for specially arranging the power mechanism, simple structure, low manufacturing cost, no shaking caused by the rotation of a rotating shaft and perfect juice extraction process.

The utility model discloses a realize like this, the gearbox comprises a gearbox, connect the motor on the gearbox, the setting passes through the rotating member that speed change mechanism drove by the motor in the gearbox, a rotating shaft, the thread bush, the pivot includes the non-circular axle on upper portion, be located the screw rod of the lower part below the non-circular axle, the axle center hole of rotating member is the non-circular hole that matches with the non-circular axle, the non-circular axle is by the non-circular hole that up passes the rotating member down, in the screw rod screw thread of pivot wears into the thread bush, be provided with guide structure below the gearbox, the thread bush reciprocates along guide structure, be provided with the spring between thread bush and guide structure.

When the juicer works, the motor rotates through the rotating component driven by the speed change mechanism, the rotating component drives the rotating shaft to rotate, the screw rod of the rotating shaft moves up and down along the threaded sleeve, when the rotating shaft moves upwards and is stopped by the limiting structure after moving to a set height, if the rotating shaft drives the raised head provided with the half orange of the juicer to move upwards and prop against the cap with the notch, the rotating shaft which continuously rotates generates downward pressure on the threaded sleeve through the screw rod under the pressing of the notch of the cap, and when the pressure is greater than the elastic force of the spring, the threaded sleeve overcomes the elastic force of the spring and moves downwards along the guide structure, so that the rotating shaft can continuously rotate under the condition of keeping the position unchanged, and the raised head is driven to continuously squeeze the half orange until the motor stops working or performs reverse driving; when the motor is driven reversely, the rotating shaft drives the raised head to continue to rotate reversely in the original position, and the juicing work is continued until the threaded sleeve leans against the lower surface of the gear box and cannot move upwards.

The motor rotates through a rotating component driven by the speed change mechanism, the rotating component drives the rotating shaft to rotate, a screw rod of the rotating shaft rotates relative to the threaded sleeve, the screw rod moves up and down relative to the threaded sleeve, and therefore the rotating shaft moves up and down. The non-circular shaft on the upper part of the rotating shaft is matched with the non-circular hole of the rotating member, so that the rotating shaft can move up and down along the non-circular hole, and meanwhile, the rotating shaft cannot rotate relative to the rotating member, so that the rotating member can drive the rotating shaft to rotate, and thus, a special moving space for arranging a power mechanism is not needed in a machine body, and the machine body is simple in structure and low in manufacturing cost.

The up-and-down movement and the rotation of the rotating shaft are always carried out under the guiding and supporting of the threaded sleeve, so that the rotating shaft can not shake, and the situation that the thread is damaged or the threaded sleeve cannot be screwed in is avoided.

The juicing process can be completed perfectly only if the juicing head exerts larger force on half of the oranges as the juicing is closer to the orange peels of half of the oranges, which is determined by the juicing process, and in fact, the juicing process is not easy to complete perfectly because the juicing head in the prior art exerts smaller force on half of the oranges as the juicing head is closer to the orange peels of half of the oranges; adopt this patent application technique, because along with the pivot up removes, the direction of the plush copper of the juice extractor that makes the pivot drive leans on toward half orange, and the thread bush just more moves toward the spring direction, and the produced elasticity of spring after being compressed is just bigger, and the plush copper that makes the pivot drive is used in the pressure on half orange just bigger to guarantee to accomplish the process of squeezing the juice perfectly.

Compared with the prior art, the utility model, have need not to set up power unit's removal space specially, simple structure, low in manufacturing cost, pivot rotate can not rock, the perfect advantage of process of squeezing the juice.
