[0016] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0017] See Figure 1 To further elaborate on this application: A fluid condiment delivery pump, used for conveying fluid condiments, includes a pump body 10, a power assembly and a one-way assembly 20, and a rotor assembly 30 disposed within the pump body 10. The condiment is a fluid condiment, such as soy sauce, vinegar, cooking wine, or brine. Of course, this application can also be used to convey other media such as water and oil.

[0018] In this embodiment, the pump body 10 is provided with a discharge channel 120 and a feed channel 110 that connect to the rotor assembly 30. The discharge channel 120 is connected to a feeding pipe, which is used to add seasonings into the cooking machine; the feed channel 110 is provided with a suction pipe that connects to the seasoning bottle.

[0019] The discharge channel 120 includes a first channel 120A and a second channel 120B. The first channel 120A and the feed channel 110 form a first flow channel 40 for adding seasonings; the second channel 120B and the feed channel 110 form a second flow channel 50 for recirculation. The rotor assembly 30 is used to drive the flow of seasonings within the first flow channel 40 and the second flow channel 50.

[0020] The unidirectional components 20 are respectively disposed in the first flow channel 40 and the second flow channel 50, and are used to control the opening and closing of the first flow channel 40 and the second flow channel 50; the power component is used to drive the rotor assembly 30 to rotate in the correct direction. The power component may be an electric motor.

[0021] When the rotor assembly 30 rotates in the first direction (clockwise), the second flow channel 50 closes (the one-way component in the second flow channel closes it), and the rotor assembly 30 drives the seasoning to be discharged from the discharge channel 120 along the first flow channel 40. Specifically, the rotor assembly 30 generates negative pressure to draw the seasoning along the first flow channel 40 and convey it into the cooking machine for feeding.

[0022] When the rotor assembly 30 rotates in the second direction (counterclockwise), the first flow channel 40 closes (the one-way component within the first flow channel closes it), and the rotor assembly 30 drives the seasonings within it to flow back along the second flow channel 50. The seasonings in the extraction pipe, the feeding pipe, and the rotor assembly 30 all flow back into the seasoning bottle, preventing blockages caused by drying and avoiding spoilage due to prolonged contact with the external environment.

[0023] When in use, as the rotor assembly 30 rotates in the first direction, the seasoning is drawn in through the extraction pipe, transported from the first flow channel 40 to the feeding pipe for discharge, thus adding seasoning.

[0024] When not in use, when the rotor assembly 30 rotates in the second direction, the rotor assembly 30 drives the seasoning in the feeding pipe, the rotor assembly 30, the first flow channel 40, the second flow channel 50 and the extraction pipe to flow back into the seasoning bottle, thereby preventing the seasoning from remaining in the pump body 10 and the feeding pipe and extraction pipe.

[0025] Combination Figure 1 In this embodiment, the one-way component 20 includes a first one-way valve 20A disposed in the first flow channel 40 and a second one-way valve 20B disposed in the second flow channel 50. The first one-way valve 20A and the second one-way valve 20B are arranged in opposite directions. Under normal conditions, the first one-way valve and the second one-way valve 20B respectively close the first flow channel 40 and the second flow channel 50.

[0026] Both the first one-way valve 20A and the second one-way valve 20B include an elastic element 220 and a sealing body 210. The elastic element 220 is used to push the sealing body 210 to block the first flow channel 40 and / or the second flow channel 50. The sealing body 210 can be spherical, and the elastic element 220 can be a spring. In the normal state, the elastic element 220 pushes the sealing body to block the first flow channel 40 and the second flow channel 50. In the prior art CN213371321U, it can be seen that the height of the feeding head for adding seasoning is higher than the height of the pump. Thus, when the seasoning is added, the seasoning in the feeding head can easily flow back, which will affect the amount of seasoning added next time. Compared with the prior art, in this application, when the addition of seasoning is stopped, the first one-way valve 20A and the second one-way valve 20B can block the first flow channel 40 and the second flow channel 50, preventing the seasoning from flowing back, and thus enabling precise control of the amount of seasoning added next time.

[0027] To facilitate the installation and disassembly of the one-way component 20, an adapter 60 is detachably connected to the pump body 10. The discharge channel 120 is located within the adapter 60, and the one-way component 20 is located between the adapter 60 and the pump body 10. The one-way component 20 can be installed or replaced by disassembling the adapter 60.

[0028] The rotor assembly 30 forms a conveying channel for transporting seasonings, which connects the discharge channel 120 to the first flow channel 40 and the second flow channel 50, respectively. The rotor assembly 30 includes a first rotor 310 and a second rotor 320 eccentrically disposed within the first rotor 310. The power assembly is connected to the second rotor 320. The second rotor 320 divides the first rotor 310 into a first cavity 30A and a second cavity 30B. The feed channel 110 connects to the second cavity 30B, the discharge channel 120 connects to the first cavity 30A, and the conveying channel connects the first cavity 30A and the second cavity 30B, allowing seasonings to flow between the two cavities. The overall structure is compact, with low pressure pulsation and high precision.

[0029] When the rotor assembly 30 rotates clockwise, cavity 30A is a low-pressure cavity and cavity 30B is a high-pressure cavity. The seasoning is drawn into cavity 30A, compressed by the rotor assembly 30, and enters cavity 30B through the conveying channel, and is discharged from the first flow channel 40. When the rotor assembly 30 rotates counterclockwise, cavity 30A is a high-pressure cavity and cavity 30B is a low-pressure cavity. The seasoning flows back from the pump body 10 to the seasoning bottle.

[0030] It is understood that the flow rate pumped out by the second rotor 320 rotating once inside the first rotor 310 is fixed. The amount of rotation of the first rotor 310 driven by the second rotor 320 is controlled by the power component, thereby precisely controlling the amount of seasoning added.

[0031] In this embodiment, a first sealing element 70 is provided between the pump body 10 and the adapter 60 for abutting against the one-way component 20. The first sealing element 70 can be a sealing ring; under normal conditions, the elastic element 220 pushes the sealing body 210 against the first sealing element 70, thus further improving the sealing performance.

[0032] A second sealing element 80 is also provided between the pump body 10 and the adapter 60 to seal the pump body 10 and the adapter 60. The second sealing element 80 can be a sealing ring to prevent the seasoning from leaking out of the first flow channel 40 and the second flow channel 50.

[0033] In this embodiment, the power component is integrated on the pump body 10 and arranged coaxially with the rotor assembly 30. The power component drives the rotor assembly 30 to rotate through the drive shaft, which can reduce the overall volume.
