The grinding and boiling are usually done in the same cavity. That is, the soymilk machine first grinds beans or other ingredients and water in the cavity to form pulp, and then automatically starts the heating program to heat and boil the pulp in the cavity after the grinding is completed.

[0003] In order to improve the convenience of using soybean milk machines and enhance the market competitiveness of products, more and more manufacturers choose to add functions such as automatic water inlet, automatic beverage discharge and automatic cleaning to soybean milk machines, such as a soybean milk machine with a self-cleaning pulp cup disclosed in the utility model with publication number CN211484199U, an easy-to-clean soybean milk machine disclosed in the utility model with publication number CN114732301A, and a grinding soybean milk machine disclosed in the utility model with publication number CN205162780U. In order to achieve the above functions, it is often necessary to install a conduit, a solenoid valve for driving the conduit switch, and a driver for driving the conduit to adjust the direction, etc. in the soybean milk machine.

The two pipe clamps 5 are respectively hinged to the housing 4 and have positioning columns 51. The through hole 321 is not a circular hole and can make the two pipe clamps 5 clamp or release the hose section together when rotating. Among them, the two positioning columns 51 are respectively arranged close to the through hole 321.

The plug-in surfaces of the upper pipe 1 and the lower pipe 2 are provided with concave and convex edges.

[0035] The driving assembly 3 also includes a driving gear 31, a lower gear plate 33, a motor 34 and a transmission gear 35. The upper gear plate 32 and the lower gear plate 33 are coaxially fixed outside the upper tube 1 and the lower tube 2 respectively. The motor 34 indirectly drives the driving gear 31 located between the upper gear plate 32 and the lower gear plate 33 to rotate through the transmission gear 35. The driving gear 31 drives the upper gear plate 32 or the lower gear plate 33 to rotate separately through the clutch structure.

[0036] The central axes of the driving gear 31 and the upper gear plate 32 may intersect to form an angle, and the driving gear 31 and the lower gear plate 33 are coaxially arranged.

[0037] The clutch structure includes a protrusion 331, a ramp 431 and a stopper 432, wherein the protrusion 331 and the ramp 431 are respectively arranged on the lower gear plate 33 and the housing 4, and the lower gear plate 33 is meshed with the driving gear 31 when the protrusion 331 is located at the bottom of the ramp 431, and the lower gear plate 33 can drive the driving gear 31 to approach the upper gear plate 32 while the protrusion 331 goes uphill along the ramp 431, and the stopper 432 is located at the top of the ramp 431 and can prevent the lower gear plate 33 from continuing to mesh with the driving gear 31.

[0038] The shell 4 includes a base 41, an upper cover 42 and a lower cover 43.

[0039] A spring 6 is provided between the upper tube 1 and the driving gear 31 to press the driving gear 31 toward the lower toothed disc 33 .

[0040] Working process of this utility model:

[0041] Take the installation in a soymilk maker as an example, see Figure 1 After the motor 34 is started, on the one hand, the two pipe clamps 5 can clamp or loosen the hose section to achieve the cutting or conducting of the upper pipe 1, and on the other hand, the free end of the lower pipe 2 can be adjusted in direction to achieve the zoned discharge of different slurries.

[0042] For the driving assembly 3, the motor 34 can drive the driving gear 31 to rotate forward or reverse (such as Figure 1 As shown in Figure 2 , Figure 6 and Figure 7 As shown, initially, the driving gear 31 is pressed by the spring 6 and is at the bottom in the housing 4 and meshes with the lower toothed disc 33 (there is a gap between the driving gear 31 and the upper toothed disc 32). At this time, if the driving gear 31 rotates forward, the lower toothed disc 33 will rotate with the driving gear 31 on the one hand, and will slowly lift the driving gear 31 through the protrusion 331 gradually ascending along the slope 431 on the other hand. When the protrusion 331 is blocked by the stopper 432, the driving gear 31 will be disengaged from the lower toothed disc 33 on the one hand, and meshed with the upper toothed disc 32 on the other hand (that is, the driving gear 31 rotates to drive the upper toothed disc 32 to rotate, see Figure 8). Similarly, when the protrusion 331 moves down the slope 431, the driving gear 31 will gradually separate from the upper gear plate 32 and drive the lower gear plate 33 to rotate again (the driving gear 31 and the lower gear plate 33 are lowered as a whole).

[0043] For the working state switching of the upper tube, Figures 3 to 5 As shown, during the rotation of the upper toothed disc 32 , the two positioning posts 51 will move along the elliptical inner contour of the through hole 321 , thereby adjusting the spacing between the flat surfaces of the two pipe clamps 5 (the rotational movement of the upper toothed disc 32 is converted into the opening and closing movement of the two pipe clamps 5 ).

[0044] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
