Among them, one of the pressing plate and the extrusion barrel is provided with a protrusion, and the other is provided with a notch matching the protrusion, and the protrusion is arranged in the notch.

[0008] The present application sets the pressing plate between the feed chamber and the juice extraction chamber, so that the juice extraction material can be squeezed after being cut by the cutting edge in the feed chamber, reducing the load on the motor and other juicer components due to the squeezing of large pieces of food, and on the other hand reducing the probability of the debris of the juice extraction material in the juice extraction chamber splashing out. At the same time, one of the pressing plate and the squeezing cylinder is provided with a protrusion, and the other is provided with a notch matching the protrusion, so that when the pressing plate is set on the squeezing cylinder, the installation and positioning effect is better, and the convenience of installation is improved.

[0009] In a preferred implementation of the juicer, the pressing plate includes a body and an outer peripheral edge arranged on the outer periphery of the body, the feed inlet is arranged on the body, and the protrusion or notch is arranged on the outer peripheral edge.

[0010] The present application provides a feed port on the main body of the pressing plate to facilitate the entry of the juicing material after cutting into the juicing chamber.

[0020] At least part of the projection of the second side surface of the feed port of the present application is an arc segment, so that when the cutting edge cuts the juicing material, the second side surface can limit the juicing material, thereby improving the cutting effect of the juicing material.

[0021] In a preferred implementation of the juice extractor, the upper surface of the pressing plate includes a transition surface, and the height of the transition surface gradually decreases along the rotation direction of the cutting edge.

[0022] In the present application, the upper surface of the pressure plate also includes a transition surface, and the height of the transition surface gradually decreases along the rotation direction of the cutting edge, thereby guiding the juicing material, facilitating the juicing material to enter the juicing chamber through the feed port, and improving the juicing efficiency.

On the other hand, the speed at which the juicing material enters the juicing chamber will not be too fast, thereby improving the cutting effect.

[0025] In a preferred implementation of the juice extractor, the outer peripheral surface of the pressing plate abuts against the inner wall of the feeding barrel.

[0026] In the present application, the outer peripheral surface of the pressure plate abuts against the inner wall of the feed barrel, and the pressure plate is limited in the horizontal direction by the inner wall of the feed barrel, thereby improving the stability of the pressure plate installation.

Figure 7 In a preferred implementation of the juice extractor 1, along the rotation direction Z of the cutting edge 32, the transition surface 333 has a starting end 3331 and an ending end 3332, and there is a height difference h between the starting end 3331 and the ending end 3332, which satisfies 0<h≤10mm.

[0098] It should be noted that, along the rotation direction Z of the cutting edge 32 , the transition surface 333 may have a starting end 3331 and an ending end 3332 , and the transition surface 333 may be connected to the first side surface 3312 at the ending end 3332 .

[0099] It should be noted that the height difference h between the starting end 3331 and the tail end 3332 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0100] It should be noted that the upper surface of the pressing plate 33 may be a plane and a transition surface 333. The plane is arranged along the horizontal direction X, and the plane may be connected to the second side surface 3313. The plane is connected to the starting end 3331 of the transition surface 333, and the height difference h between the starting end 3331 and the end 3332 may be the height difference between the end 3332 and the plane.

[0101] In the present application, the height difference between the starting end 3331 and the ending end 3332 of the transition surface 333 meets the above conditions, and can guide the juicing material, making it easier for the juicing material to enter the juicing chamber 21 through the feed port 3311, thereby improving the juicing efficiency. On the other hand, the speed at which the juicing material enters the juicing chamber 21 will not be too fast, thereby improving the cutting effect.

[0102] In a preferred implementation of the juice extractor 1 , the outer peripheral surface of the pressing plate 33 abuts against the inner wall of the feeding barrel 10 .

[0103] It should be noted that the feed cylinder 10 and the extrusion cylinder 20 can be connected by threads.

[0104] It should be noted that the inner diameter of the lower end of the feed cylinder 10 can be larger than the inner diameter of the upper end of the extrusion cylinder 20. When the feed cylinder 10 is connected to the extrusion cylinder 20, the lower end of the feed cylinder 10 can be sleeved on the upper end of the extrusion cylinder 20. At the same time, the pressing plate 33 is connected to the upper end of the extrusion cylinder 20, that is, the outer peripheral surface of the pressing plate 33 abuts against the inner wall of the feed cylinder 10.

[0105] In the present application, the outer peripheral surface of the pressing plate 33 abuts against the inner wall of the feed barrel 10 , and the pressing plate 33 is limited in the horizontal direction X by the inner wall of the feed barrel 10 , thereby improving the stability of the installation of the pressing plate 33 .

[0106] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
