[0028] Please refer specifically to Figure 1-6 , a food processor, comprising a base 1, a cup body 2, a sound insulation cover 3 and a water tank 4. The cup body 2 is installed on one side of the base 1, the sound insulation cover 3 is installed on the base 1 and covers the outside of the cup body 2 to play a role in sound insulation for the cup body 2, and the water tank 4 is installed on the other side of the base 1 to supply water to the cup body 2. Inside the cup body 2, there are provided a motor 5, a heating plate 6 and a cutter assembly 7. The motor shaft 501 of the motor 5 is a hollow structure, that is, the motor 5 is a hollow shaft motor 5. One end of the motor shaft 501 passes through the heating plate 6 and is connected to the cutter assembly 7 through a fastener 15. When the motor 5 operates, it drives the cutter assembly 7 to rotate, thereby cutting and crushing food ingredients.

[0029] The fastener 15 is provided with a through hole that penetrates the upper and lower end faces of the fastener 15, that is, the fastener 15 has a hollow structure at this position. The other end of the motor shaft 501 extends downward to the bottom of the cup body 2, and a rotary joint 8 is connected to this end of the motor shaft 501, that is, the rotary joint 8 is a hollow structure. The hollow shaft motor 5, the hollow fastener 15 and the hollow rotary joint 8 are all used for the water path; there is also a water path structure connected to the rotary joint 8.

[0030] In this embodiment, the rotary joint 8 can adopt a commercially available rotary joint 8. Specifically, the rotary joint 8 includes a rotary part 801 in the upper half and a fixed part 802 in the lower half. A bracket 14 is arranged outside the motor 5. The rotary part 801 is connected to the motor shaft 501 and can rotate together with the motor shaft 501. The fixed part 802 is fixedly installed on the bracket 14. The bracket 14 is in a [shape structure, and the fixed part 802 of the rotary joint 8 is fixed in the middle.

[0031] The waterway structure includes a water outlet valve 9, a water outlet mechanism 10, a water pump 11, a pipeline 12 and a connector 13. The water outlet valve 9 is installed at the bottom of the water tank 4. The water outlet mechanism 10 is installed in the base 1 and is located below the water outlet valve 9. The water outlet mechanism 10 is connected to the inlet end of the water pump 11. The water pump 11 is installed in the base 1. One end of the pipeline 12 is connected to the outlet end of the water pump 11, and the other end is connected to the connector 13. The connector 13 is of an L-shaped structure, and its two ends are respectively connected to the pipeline 12 and the rotary joint 8.

[0032] There is a water outlet hole 401 at the bottom of the water tank 4. The water outlet valve 9 is installed in the water outlet hole 401. The water outlet valve 9 includes a valve core 901, a return spring 902 and a sealing ring 903. The valve core 901 is installed in the water outlet hole 401. The return spring 902 is sleeved on the outer wall of the valve core 901. The sealing ring 903 is sleeved on the top of the valve core 901 and has a diameter larger than that of the water outlet hole 401. When the valve core 901 is not stressed, the return spring 902 is in a normal state, and the sealing ring 903 will block the water outlet hole 401 to prevent the water in the water tank 4 from flowing out. There is an installation groove 402 at the bottom of the water outlet hole 401. A part of the valve core 901 penetrates into the installation groove 402. The two ends of the return spring 902 respectively abut against the inner top surface of the installation groove 402 and the bottom surface of the valve core 901. There are several vertically extending flow channels 9011 on the outer wall of the valve core 901. The middle part of the valve core 901 is in an approximate cross-shaped column shape, so as to evenly divide the space inside the valve core 901 into four flow channels 9011, which can make the water outlet more uniform.

[0033] The water outlet mechanism 10 includes a housing 1001 and a jacking member 1002. The inner wall of the housing 1001 is closely attached to the outer wall of the installation groove 402. The jacking member 1002 is installed in the inner cavity of the housing 1001 and is located below the valve core 901. There are several water outlet ports 10021 on the jacking member 1002. There is a water outlet pipe 1210011 on the housing 1001. The water outlet pipe 1210011 is connected to the inner cavity of the housing 1001, and the other end is connected to the inlet end of the water pump 11.

[0034] The water outlet mechanism 10 and the water outlet valve 9 can be used in cooperation. The plug-in connection method of the water outlet mechanism 10 and the water outlet valve 9 is similar to that of a quick-connect joint. One is used as a male joint and the other is used as a female joint. The structure is small and compact, and quick disconnection and connection can be achieved. Specifically, when the water tank 4 is installed on the base 1, the water outlet mechanism 10 and the water outlet valve 9 cooperate. At this time, the ejector rod abuts against the lower end of the valve core 901, applying an upward external force to the valve core 901, driving the valve core 901 and the sealing ring 903 to move upward, and the return spring 902 is compressed to open the water outlet hole 401; when the water tank 4 is removed from the base 1, the return spring 902 resets, applying a downward reset force to the valve core 901 and the sealing ring 903, and the valve core 901 and the sealing ring 903 move downward to close the water outlet hole 401.

[0035] Preferably, the pipe 12 is a flexible hose, and the advantage of the flexible hose is that it can be bent freely, which is convenient for layout.

[0036] The present utility model is a food processor, and its working principle is described in conjunction with the accompanying drawings:

[0037] The water pump 11 works to pump the water in the water tank 4 into the cup body 2 from the water tank 4. The water flow direction is: water tank 4 → water outlet hole 401 → flow channel 9011 → installation cavity → water outlet 10021 → housing 1001 → water outlet pipe 1210011 → water pump 11 → pipe 12 → connector 13 → rotary joint 8 - motor shaft 501 - fastener 15 - cup body 2. During the water supply process, the water will pass through the motor 5. When passing through the motor 5, the water plays a role in water cooling, cooling the motor 5 body, and at the same time using water cooling to replace the original air cooling, playing a role in noise reduction.

[0038] The motor 5 works to drive the tool assembly 7 to rotate, thereby cutting and crushing the food ingredients, and at the same time heating through the heating plate to heat the mixture of food ingredients and water.

[0039] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
