Description

Juice extractor

Technical Field

The invention relates to a juicer for juicing orange juice.

Background

An existing juice extractor, such as an orange juice extractor with a chinese patent number of 2009100380122, see the attached drawing 4 of the specification, a sleeve 14 is fixedly connected to a machine body 1, a screw 13 is in threaded connection with the sleeve 14, the sleeve is stationary, the screw rises along the sleeve by rotation, in order to ensure that an output shaft of a motor, the screw and an axial line of the sleeve coincide, the processing precision requirements of the screw and the sleeve are very high, the processing precision of the sleeve is particularly difficult, the sleeve can be shorter in length originally, and a nut is used for realizing the function of the juice extractor, so that the processing precision of the sleeve is facilitated, but if the sleeve is not long enough, the screw can shake, and in order to ensure that the screw does not shake, the sleeve needs to be as long as possible. The machining of the sleeve is thus limited to two difficulties.

The applicant also has an automatic juice extractor of chinese patent application No. 2016100547629, see fig. 6 of the specification, and in order to ensure that the screw 73, the screw hole 65 and the output shaft 93 are coaxial, the motor of the automatic juice extractor is stationary, the screw is forced to rotate and ascend relative to the screw hole by the rotation of the output shaft, and the use finds that the screw 73 is still clamped and does not ascend because the axes of the screw 73, the screw hole 65 and the output shaft 93 are hardly located on the same axial line.

The basic ideas of the two patent products are still in a blocking mode, firstly, nuts are not moved, the machining precision of each part is high as much as possible, the parts are ensured to be positioned on the same axis, and the parts are not found to be sold through practice inspection. And the screw rods of the two patent products stop several seconds after reaching the highest point and immediately descend, the screw rods cannot be controlled to idle after reaching the highest point, and food materials cannot be squeezed better during juicing, so that waste is caused.

Disclosure of Invention

Therefore, the invention aims to provide the juice extractor which adopts a dredging mode to allow the nut and the screw to deviate in a small radial range so as to reduce the processing difficulty of each part and can enable the screw to rise to the highest point for idling.

The object of the invention is thus achieved.

The utility model provides a juicer, includes casing, juice cup, bowl cover, goes up and presses the head, presses head, screw rod, motor down, goes up and presses the head and install in the bowl cover, and the screw rod top stretches into in the juice cup, presses the head down and installs on the screw rod top, and the juice cup is installed on the casing, and the motor is installed in the casing and reciprocates in the casing, and reduction gear is installed to the motor output, and the screw rod is connected with reduction gear's output, the screw rod periphery is equipped with the sleeve, has the nut activity to locate in the sleeve, but the nut can not sleeve relatively rotate, screw rod and nut screw-thread fit, and the nut top is equipped with the spring, and the nut below is equipped with down the spring, and it all is located the sleeve to go up the spring and the spring withstands the nut down.

The technical scheme can be further perfected as follows.

A gap is reserved between the inner wall of the sleeve and the outer wall of the nut.

The reduction gear is a planetary reduction gear.

The outer surface of the nut is in a non-circular shape, the cross section of the inner cavity of the sleeve is in a non-circular shape, and the shape of the nut is matched with that of the inner cavity of the sleeve.

The juice cup is provided with a juice outlet, and the juice cup and the machine shell are integrally inclined towards the juice outlet.

The axial leads of the screw and the motor are inclined and incline towards the juice outlet side.

The nut and the screw rod of the invention can shift in the sleeve in a small range, the screw rod can not be blocked, although the collision of the nut and the sleeve can generate sound, the noise problem can be solved by materials or adding a damping device (or damping oil) to the nut. The nut can ascend or descend along with the screw rod at the initial stage, is movably arranged in the sleeve, is convenient to process due to short length, is easy to control the inner diameter of the nut, and cannot be locked when in use due to the fact that the screw rod is allowed to swing. The screw rod can idle after rising to the highest point, and the juice is more thoroughly squeezed.

Fig. 2 is a schematic structural view of a sleeve, a screw, a motor and the like.

Detailed Description

The invention is further described in detail below with reference to the figures and examples.

The embodiment is combined with the attached drawing, the juice extractor comprises a machine shell 1, a juice cup 2, a cup cover 3, an upper squeezing head 4, a lower squeezing head 5, a screw rod 6 and a motor 7, wherein the upper squeezing head 4 is installed in the cup cover 3, the top end of the screw rod 6 extends into the juice cup 2, the lower squeezing head 3 is installed at the top end of the screw rod 6, the juice cup 2 is installed on the machine shell 1, the motor 7 is installed in the machine shell 1 and moves up and down in the machine shell, a planetary reduction gear 8 is installed at the output end of the motor 7, and the screw rod 6 is connected with the output end of the planetary reduction gear 8.
