[0031] like Figure 1 and Figure 2 As shown, this application provides a juicer 10, which includes a juicing head 100, a power unit 200, and a reset mechanism 300. The juicing head 100 has a drive shaft 110; the power unit 200 has a power shaft 210, which can mesh with the drive shaft 110. The power unit 200 can drive the juicing head 100 to rotate through the meshing between the power shaft 210 and the drive shaft 110. When the juicing head 100 is pressed, the drive shaft 110 can be driven to move towards the power shaft 210, so that the drive shaft 110 meshes with the power shaft 210. The reset mechanism 300 includes, but is not limited to, a spring 310. The reset mechanism 300 is used to provide a reset force to the juicing head 100 when the juicing head 100 is released, so as to drive the drive shaft 110 to move away from the power shaft 210, so that the drive shaft 110 separates from the power shaft 210.

[0032] The juicer 10 provided in this application, when the juicing head 100 is pressed, the drive shaft 110 of the juicing head 100 can be driven to move towards the power shaft 210 of the power unit 200, so that the drive shaft 110 and the power shaft 210 mesh. At this time, the power unit 200 can drive the juicing head 100 to rotate through the meshing transmission between the power shaft 210 and the drive shaft 110, so that the juicer 10 works. When the juicing head 100 is released, the reset mechanism 300 can provide a reset force to the juicing head 100 to drive the drive shaft 110 to move away from the power shaft 210, so that the drive shaft 110 and the power shaft 210 are separated, so that the juicer 10 stops. Therefore, this application realizes the jogging function of the juicer 10 by switching the meshing and disengaging states between the drive shaft 110 and the power shaft 210, ensuring the safety of the juicer 10 and avoiding accidental activation of the juicer 10, which could cause physical harm to the user.

[0033] In one embodiment, the power shaft 210 can be sleeved with the transmission shaft 110; specifically, in this embodiment, the power shaft 210 can be inserted into the transmission shaft 110, such as... Figure 2 As shown, specifically, one end of the drive shaft 110 is provided with a mating hole 111, and one end of the power shaft 210 can be inserted into the mating hole 111. It is understood that in other embodiments, the power shaft 210 can be sleeved on the outside of the drive shaft 110, as long as meshing transmission between the power shaft 210 and the drive shaft 110 can be achieved. Specifically, the power shaft 210 and the drive shaft 110 are coaxially arranged.

[0034] In one embodiment, the drive shaft 110 is provided with a first engaging portion, and the power shaft 210 is provided with a second engaging portion. The first engaging portion can engage with the second engaging portion. Specifically, one end of the drive shaft 110 is provided with a mating hole 111, the inner wall of the mating hole 111 is provided with the first engaging portion, and one end of the drive shaft 110 is provided with the second engaging portion. When one end of the drive shaft 110 is inserted into the mating hole 111, the second engaging portion engages with the first engaging portion.

[0035] In one embodiment, the first meshing portion includes at least four meshing surfaces disposed on the peripheral wall of the drive shaft 110, and the second meshing portion includes at least four meshing surfaces disposed on the peripheral wall of the power shaft 210. Each meshing surface of the first meshing portion can mesh with each meshing surface of the second meshing portion. This arrangement allows for more stable meshing of the drive shaft 110 and the power shaft 210, and also facilitates easier alignment of the drive shaft 110 and the power shaft 210. Thus, if the initial positions of the drive shaft 110 and the power shaft 210 are not suitable, alignment can be achieved by rotating the drive shaft 110 by a small angle. Specifically, the first meshing portion includes at least four meshing surfaces disposed on the inner wall of the mating hole 111 and distributed circumferentially, and the second meshing portion includes at least four meshing surfaces disposed at one end of the power shaft 210 and distributed circumferentially.

[0036] In an optional embodiment, the first meshing portion includes six meshing surfaces disposed on the peripheral wall of the drive shaft 110, and the second meshing portion includes six meshing surfaces disposed on the peripheral wall of the power shaft 210. Each meshing surface of the first meshing portion can mesh with each meshing surface of the second meshing portion. Specifically, the first meshing portion includes six meshing surfaces disposed on the inner wall of the mating hole 111 and distributed circumferentially, and the second meshing portion includes six meshing surfaces disposed at one end of the power shaft 210 and distributed circumferentially. That is, the first meshing portion is an internal hexagonal structure disposed at one end of the drive shaft 110, and the second meshing portion is an external hexagonal structure disposed at one end of the power shaft 210.

[0037] In one embodiment, in order to ensure stable meshing between the drive shaft 110 and the power shaft 210, when the juicing head 100 is pressed, the drive shaft 110 moves in a direction closer to the power shaft 210 with a stroke ≥0.3mm.

[0038] It is understandable that, since there is a certain meshing force between the drive shaft 110 and the power shaft 210, if the stroke of the reset mechanism 300 is too short, the drive shaft 110 and the power shaft 210 may not be able to separate. In order to ensure that the drive shaft 110 and the power shaft 210 can be separated by the reset force of the reset mechanism 300 when the juicing head 100 is in the released state, the maximum stroke of the reset mechanism 300 is ≥3mm.

[0039] In one embodiment, the juicing head 100 is used to juice ingredients with peels, such as oranges. Specifically, the ingredients with peels are pressed against the juicing head 100 and juiced by rotating the juicing head 100. There is no need to peel the ingredients beforehand, making the operation convenient and the juicing efficiency high.

[0040] like Figure 3 As shown, in one embodiment, the juicing head 100 further includes a juicing head body 120 connected to the drive shaft 110. The cross-sectional area of ​​the juicing head body 120 increases from the end of the juicing head body 120 away from the drive shaft 110 to the end of the juicing head body 120 connected to the drive shaft 110, and the minimum cross-sectional area of ​​the juicing head body 120 is ≤10mm². 2 This is done to squeeze the ingredients as cleanly as possible and increase the juice yield.

[0041] In one embodiment, the juicing head body 120 is hemispherical or conical, and its shape matches the shape of the food with peel. With this configuration, by cutting a food with peel, such as an orange, in half and then placing the cut side of the food with peel facing the juicing head body 120, the juicing head body 120 can make close contact with the food with peel, thereby achieving effective juicing and significantly improving the juicing efficiency of the juicing head 100.

[0042] like Figure 3 As shown, in one embodiment, the surface of the juicing head body 120 is provided with longitudinally distributed scraper blades 130, and the number of scraper blades 130 is ≥2. Specifically, at least two scraper blades 130 are evenly distributed on the surface of the juicing head body 120. This arrangement allows the user to press the food with peel against the scraper blades 130, and juice is achieved by rotating the scraper blades 130. The operation is convenient and the juicing efficiency is high.

[0043] like Figure 1 and Figure 4As shown, in one embodiment, the juicer 10 further includes a juicing cup 400, a juicing head 100 rotatably disposed within the juicing cup 400, and the juicing head 100 is movable relative to the juicing cup 400 along the axial direction of the juicing head 100. At least a portion of the power shaft 210 extends into the juicing cup 400, and a reset mechanism 300 is disposed between the juicing head 100 and the juicing cup 400.

[0044] In one embodiment, the juicing cup 400 includes an upper cup body 410 and a lower cup body 420. The upper cup body 410 is disposed on the lower cup body 420 and the upper cup body 410 and the lower cup body 420 are coaxially arranged. The upper cup body 410 has a juicing chamber 411 and the lower cup body 420 has a juice collecting chamber 421. The bottom of the upper cup body 410 is provided with a through hole 430 connecting the juicing chamber 411 and the juice collecting chamber 421. The juice collecting chamber 421 is provided with a juice outlet 440 connected to the outside. The juicing head 100 is rotatably disposed in the juicing chamber 411, and the drive shaft 110 extends into the juice collecting chamber 421 through the bottom of the upper cup body 410. At least a portion of the power shaft 210 extends into the juice collecting chamber 421. Specifically, after the juicing head 100 in the juicing chamber 411 extracts juice from the food, the juice flows into and is stored in the juice collection chamber 421 through the through hole 430 and is discharged through the juice outlet 440. In one embodiment, to improve the juicing efficiency, there are two juice outlets 440, which are located on opposite sides of the juice collection chamber 421. In another embodiment, to improve the flow efficiency of the juice, the through hole 430 includes a central hole 431 and a plurality of edge holes 432 disposed around the central hole 431. The central hole 431 and the edge holes 432 are connected, allowing the juice in the juicing chamber 411 to flow into and be stored in the juice collection chamber 421 through the central hole 431 and the edge holes 432.

[0045] like Figure 3 As shown, in one embodiment, the juicing head 100 further includes a limiting portion 140, which is disposed on the outer side wall of the juicing head body 120. The limiting portion 140 is used to limit the movement of the juicing head 100 in its own axial direction, preventing the juicing head 100 from being moved out of the juicing chamber 411 due to excessive pressure from the user. Specifically, the limiting portion 140 can abut against the bottom wall of the juicing chamber 411 to limit the movement of the juicing head 100 in its own axial direction. Specifically, there are two limiting portions 140, which are disposed on opposite sides of the juicing head body 120.

[0046] like Figure 1 and Figure 2As shown, in one embodiment, a protrusion 450 is provided at the bottom of the upper cup body 410. The protrusion 450 is located at the middle of the bottom of the upper cup body 410, extends into the juice collection cavity 421, and extends towards the bottom end of the juice collection cavity 421. The drive shaft 110 passes through the protrusion 450. The reset mechanism 300 includes a spring 310, which is sleeved on the outside of the drive shaft 110 and abuts against the protrusion 450. Furthermore, to improve the strength of the upper cup body 410, a plurality of connecting ribs 433 are also provided at the bottom of the upper cup body 410. Each connecting rib 433 is connected between the protrusion 450 and the inner wall of the central hole 431, and the plurality of connecting ribs 433 are arranged at intervals along the circumference of the protrusion 450.

[0047] like Figure 1 As shown, in one embodiment, the juicer 10 further includes a housing 500, a juicing cup 400 mounted on the housing 500, a motor 220 of the power unit 200 disposed inside the housing 500, one end of a power shaft 210 connected to the motor 220, and the other end of the power shaft 210 extending into the juicing cup 400. Specifically, the lower cup body 420 is mounted on the housing 500, and the end of the power shaft 210 away from the motor 220 extends sequentially through the housing 500 and the lower cup body 420 into the juice collection chamber 421.
