[0043] In the prior art, water needs to pass through a detergent box pre-mixed with different detergents to form a mixture of water and detergents before flowing into the washing tub. However, part of the mixture of water and detergents remains in the washing box, causing the detergent box to mold and affect health.

[0044] Combination Figures 1 to 5 As shown, the embodiment of the present application provides a detergent dispensing component 100, comprising:

[0045] A detergent box 110, wherein the detergent box 110 has a first chamber S1, a second chamber S2 and a third chamber S3 which are arranged at intervals;

[0046] a peristaltic pump 120, wherein the peristaltic pump 120 is configured to pump the first detergent in the first chamber S1 and the second detergent in the second chamber S2 into the third chamber S3;

[0047] A venturi tube 130, wherein the venturi tube 130 is connected to the third chamber S3;

[0048] The first pipe 140 and the second pipe 150 , wherein the first pipe 140 is used to connect to an external water source, and both ends of the venturi tube 130 are connected to the first pipe 140 and the second pipe 150 , respectively.

[0049] In the detergent dispensing assembly 100 proposed in the embodiment of the present application, different detergents in the first chamber S1 and the second chamber S2 of the detergent box 110 are pumped into the third chamber S3 for mixing by the peristaltic pump 120; water flows in the first pipe 140; when the water flows through the venturi tube 130, negative pressure is generated, and the mixed detergent (hereinafter referred to as the mixed detergent) is sucked from the third chamber S3 into the venturi tube 130, and after the water flows and the detergent are mixed, they enter the second pipe 150 to complete the dispensing of the mixed detergent; because water does not enter the first chamber S1, the second chamber S2 and the third chamber S3 in the detergent box 110, there is no mixture of water and detergent remaining in the first chamber S1, the second chamber S2 and the third chamber S3, which can improve the health of the user.

[0050] In addition, the water circuit and detergent supply circuit of the embodiment of the present application are relatively independent pipelines, which are simpler in route and lower in manufacturing cost than the double-layer detergent box 110 in the prior art. Moreover, the prior art also has the problem that the detergent box 110 with a drawer often leaks because the drawer is not closed properly. In the present application, there is no water in the detergent box 110 and the drawer does not need to be closed, so there is no problem of the detergent box 110 leaking. In addition, by using the peristaltic pump 120 to put the mixture of the detergent box 110 into the third chamber S3, the ratio and amount of the mixture can be set intelligently, thereby improving the intelligence of the washing equipment.

[0051] In the embodiment, the first chamber S1 and the second chamber S2 store different types of detergents respectively; for example, the first chamber S1 and the second chamber S2 store laundry detergent and softener respectively; the first chamber S1 and the second chamber S2 store laundry detergent and disinfectant respectively; the first chamber S1 and the second chamber S2 store softener and disinfectant respectively. In some embodiments, the detergent box 110 may also be provided with a fourth chamber, and the peristaltic pump 120 is configured to pump different detergents in the first chamber S1, the second chamber S2, and the fourth chamber into the third chamber S3 for mixing, for example, the first chamber S1, the second chamber S2, and the fourth chamber store laundry detergent, softener, and disinfectant respectively.

[0052] In the following embodiments, the first chamber S1 stores laundry detergent, and the second chamber S2 stores softener.

[0053] As an optional implementation of the above embodiment, Figure 4As shown, the venturi tube 130 includes a throat 131, and the throat 131 is connected to the detergent box 110; the throat 131 has a confluence channel S4, and the confluence channel S4 is connected to the third chamber S3. In the embodiment, when the throat 131 is connected to the detergent box 110 and the water flows through the throat 131 of the venturi tube 130, a negative pressure area will be generated, and the mixed detergent in the third chamber S3 will be sucked into the confluence channel S4 under the action of the negative pressure, and mixed with water, and then carried by the water to the second pipe 150.

[0054] As an optional implementation of the above embodiment, Figure 4 As shown, the venturi tube 130 further includes a water inlet end 132 and a water outlet end 133; the water inlet end 132, the throat 131 and the water outlet end 133 are sequentially connected along the water flow direction; the diameter of the throat 131 is smaller than the diameter of the water inlet end 132 and the diameter of the water outlet end 133; the water inlet end 132 is connected to the first pipe 140, and the water outlet end 133 is connected to the second pipe 150.
