The seasoning feeding pipe 1 includes a seasoning box 11, a feeding pump 12, and a feeding nozzle 13 connected in sequence by pipes. The feeding pipe cleaning device 2 includes:

[0040] A cleaning passage is provided on the cleaning passage, which is provided with a water storage box 21 and a first reversing valve 22. The first reversing valve 22 has at least three interfaces, which are respectively connected to the water storage box 21, the seasoning box 11 and the feeding pump 12 through pipes, forming a first cleaning passage 31 from the water storage box 21 through the first reversing valve 22, the feeding pump 12 to the feeding nozzle 13 in sequence, and a second cleaning passage 32 from the water storage box 21 through the first reversing valve 22, the feeding pump 12 and back to the first reversing valve 22 to the seasoning box 11 in sequence.

[0041] In some possible implementations, a water pump 23 and a water nozzle 24 are further provided on the cleaning passage 3 . The water pump 23 is connected to the water storage box 21 through a pipe, and the water nozzle 24 is connected to the water pump 23 through a pipe.

[0042] In some possible embodiments, a second reversing valve 25 is further provided on the cleaning passage 3, and the second reversing valve 25 has at least one interface connected to the first reversing valve 22 through a pipe and one interface connected to the water inlet 20 through a pipe, forming a third cleaning passage 33 from the water inlet 20 to the first reversing valve 22.

[0043] The first reversing valve 22 plays the role of selecting whether the first cleaning passage 31 or the second cleaning passage 32 is opened: when the interface of the first reversing valve 22 connected to the feeding pump 12 is opened and the interface connected to the seasoning box 11 is closed, the first cleaning passage 31 is opened and the second cleaning passage 32 is closed; otherwise, the first cleaning passage 31 is closed and the second cleaning passage 32 is opened.

[0044] In some possible implementations, a first one-way valve 26 is further provided between the water storage box 21 and the first reversing valve 22 .

[0046] In some possible implementations, a third one-way valve 28 is further provided between the first reversing valve 22 and the second reversing valve 25 .

[0047] Opening the first one-way valve 26 can enable the first cleaning passage 31 / the second cleaning passage 32 to obtain water from the water storage box 21; closing the first one-way valve 26 can open the third one-way valve 28, so that the first cleaning passage 31 / the second cleaning passage 32 can obtain water from the water inlet 20.

[0048] Opening the second one-way valve 27 allows the water spray head 24 to obtain water from the water storage box 21 ; closing the second one-way valve 27 allows the water spray head 24 to obtain water from the water inlet 20 .

[0049] Opening the third one-way valve 28 can open the third cleaning passage 33, and the first cleaning passage 31 / the second cleaning passage 32 can obtain water from the water inlet 20; closing the third one-way valve 28 can open the first one-way valve 26, so that the first cleaning passage 31 / the second cleaning passage 32 can obtain water from the water storage box 21.

[0050] In some possible implementations, the water inlet 20 is further provided with a three-way valve 29 that is connected to the second reversing valve 25 and the water storage box 21 through a pipeline.

[0051] In some possible implementations, the water nozzle 24 is connected to the water pump 23 via the second reversing valve 25 .

[0052] The second reversing valve 25 can not only select the water source from the water storage box 21 or the water inlet 20 to the water nozzle 24, but also can obtain the water source from the water inlet 20 to the third cleaning passage 33 or the water nozzle 24. Specifically, it only needs to control the corresponding interface to open and close other interfaces, which will not be repeated.

[0053] In some possible implementations, the first reversing valve 22 and / or the second reversing valve 25 is a normally closed two-position three-way solenoid valve. The three-way valve 29 is a normally closed solenoid valve.

[0054] In some possible implementations, an MCU control unit may be further included to control the automatic switching of the first cleaning passage 31 and the second cleaning passage 32. Furthermore, the MCU may also control the automatic switching of various control valves such as the third cleaning passage 33, the first one-way valve 26, the second one-way valve 27, the third one-way valve 28, or the three-way valve 29.
