Detailed Description

In order to further describe the technical means and effects adopted by the present utility model for achieving the intended purpose, the following detailed description will refer to the specific implementation, structure, characteristics and effects according to the present utility model with reference to the accompanying drawings and preferred embodiments.

As shown in fig. 1 to 4, the present embodiment discloses a juice extractor.

Referring to fig. 1, a juice extractor includes a main machine 100 and a cup barrel 200, wherein the top of the cup barrel 200 is provided with a cup cover 500 for sealing; a juice extracting disc 300 is arranged in the cup barrel 200; the juice extracting tray 300 is driven by a driving motor 600 in the main body 100; a threaded pipe 400 is further arranged in the cup barrel 200, and the juice extracting disc 300 is in threaded connection with the threaded pipe 400; the driving motor 600 drives the juice extracting plate 300 to rotate, so that the juice extracting plate 300 rotates and moves up and down relative to the threaded pipe 400.

The above is the basic scheme of the utility model. After the main machine 100 is started, the driving motor 600 is started to drive the juice extracting disc 300 to rotate, the threaded pipe 400 and the inner wall of the cup barrel 200 are fixed, and then the juice extracting disc 300 rotates and moves up and down relative to the threaded pipe 400 under the action of threads. When juice is extracted, the juice extracting tray 300 moves upward, the space between the juice extracting tray 300 and the cup cover 500 is reduced, and the fruit on the juice extracting tray 300 is extruded to extract the juice. While the juice extracting tray 300 extracts the pulp while rotating.

Preferably, in this embodiment, the cap 500 is snap-connected to the upper end of the bowl 200.

Preferably, in this embodiment, the threaded pipe 400 has openings at the upper and lower ends, and an inner wall is provided with an internal thread b; the juice extracting plate 300 is disposed at the lower end opening of the threaded tube 400, and has an external thread a on the outer circumferential surface.

In this embodiment, the juice extracting plate 300 is located inside the threaded tube 400 and near the lower end opening of the threaded tube 400, and the moving path of the juice extracting plate 300 is also located inside the threaded tube 400.

Referring to fig. 2, in order to realize the driving function of the driving motor 600 on the juice extracting tray 300, a driving tube 700 is disposed in the main machine 100, and the driving tube 700 extends out of the main machine 100 to be connected to the juice extracting tray 300 in a limited manner; the output shaft 610 of the driving motor 600 is limited and arranged in the transmission pipe 700; the transmission pipe 700 can rotate under the drive of the driving motor 600 and can axially move relative to the output shaft 610.

The output shaft 610 of the driving motor 600 can only perform a rotational movement, and when the juice extracting plate 300 moves upward, it gradually gets out of the upper end of the output shaft 610 of the driving motor 600, making the juice extracting plate 300 unstable in rotation. The driving tube 700 is arranged, and the end part of the driving tube 700 is always connected with the juicing disc 300, so that the juicing disc 300 is ensured not to shake when rotating.

In order to realize spacing and stable connection between the transmission pipe 700 and the juice extracting disc 300, a spacing head 720 is arranged at the upper end of the transmission pipe 700, and the spacing head 720 is a polygonal cylinder; the circumferential surface of the limit head 720 is provided with a matching convex ring 721.

The bottom of the juice extracting tray 300 is provided with a connecting groove matched with the limit head 720 in shape, and the matching convex ring 721 is in interference fit with the connecting groove.

The coupling groove is provided at the center of the bottom of the juice extracting tray 300, and the stopper 720 is inserted into the coupling groove so that the juice extracting tray 300 rotates together with the rotation of the driving tube 700. The engagement collar 721 is in a transition engagement with the inner wall of the coupling groove such that the juice extracting plate 300 is tightly coupled to the driving tube 700 without a relative shaking.

Referring to fig. 3, in order to stably move the driving pipe 700 on the output shaft 610, an expanding pipe 710 is extended from the lower end of the driving pipe 700, and an inner diameter of the expanding pipe 710 is larger than an outer diameter of the output shaft 610 of the driving motor 600; a holding groove 711 is formed between the inner wall of the expansion pipe 710 and the output shaft 610, and an elastic holding member 800 is provided in the holding groove 711.

Preferably, the elastic supporting member 800 is a spring, and the lower end of the spring contacts the driving motor 600, and the upper end of the spring is located in the supporting groove 711 to contact the bottom of the groove, so as to support the driving tube 700 upward.

When the juice extracting plate 300 is positioned at the lowermost position, the driving tube 700 is also positioned at the lowermost position, and the spring is compressed on the driving motor 600; when the juice extracting plate 300 rotates and moves upwards under the action of the driving motor 600, the extrusion force of the juice extracting plate 300 received by the spring disappears, and the juice extracting plate gradually resets, and the driving pipe 700 is jacked up, so that the upper end of the driving pipe 700 is always connected to the juice extracting plate 300.

Referring to fig. 4, in order to avoid the juice extracting tray 300 from being separated from the gland due to the excessively long up-and-down moving path, a limit switch 900 is further provided in the present embodiment, and is provided in the main machine 100 for monitoring the position of the driving tube 700.

Preferably, the limit switches 900 are micro switches, and two limit switches are provided, and are disposed at the side of the transmission pipe 700 in an upper and lower position in the host 100, and can contact with the pipe expansion 710 at the lower end of the transmission pipe 700.

When the juicer is performing a juicing action, the drive pipe 700 moves up with the juicing disc 300. When the drive pipe 700 moves up to a designated position, i.e., the expander 710 contacts the upper limit switch 900, the limit switch 900 is triggered, and the main unit 100 sends a stop signal or a reverse rotation signal to the driving motor 600, the juice extracting plate 300 and the drive pipe 700 do not move up any more.

When the juicer performs a reset action, the juice tray 300 moves down and presses the driving tube 700 down. When the drive pipe 700 moves down to a designated position, that is, when the expander 710 contacts the lower limit switch 900, the limit switch 900 is triggered, and the main unit 100 sends a stop signal or a reverse rotation signal to the driving motor 600, the juice extracting tray 300 and the drive pipe 700 do not move down any more, and reach the lowest point.

The juice extracting tray 300 is a shell with an open upper end, a juice extracting tube 210 is arranged at the bottom of the cup barrel 200 in an outward extending manner, and the juice extracting tube 210 is communicated with the inner cavity of the cup barrel 200.

Preferably, in this embodiment, the juice outlet pipe 210 is provided with a sealing cover 1. The juice can flow out of the juice outlet pipe 210 by opening the sealing cap 1.

The present utility model is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present utility model.
