[0028] Referring to Figures 1 to 4 The liquid adding device 100 of the example embodiment of the present application is used to be connected with a washing machine (not shown), and the cleaning agent is diluted in the liquid adding device 100 and then enters the washing machine, so as to ensure uniform dispersion of the cleaning agent and improve the cleaning effect; at the same time, the cleaning agent is diluted in the water storage tank 11, so as to prevent the cleaning agent from condensing and causing blockage.

[0029] The liquid adding device 100 comprises a main machine 1 and a liquid storage barrel 2 assembled on the main machine 1. The liquid storage barrel 2 contains cleaning agent, including but not limited to laundry detergent, softener, and sterilizing liquid.

[0030] In some embodiments, a part of the liquid storage barrel 2 is exposed outside the main machine 1, so as to save the space of the main machine 1 and facilitate the miniaturization of the main machine 1.

[0031] In some embodiments, the liquid storage barrel 2 can be located inside the main machine 1.

[0032] In some embodiments, the liquid storage barrel 2 is detachable from the main machine 1. When the cleaning agent is used up, the cleaning agent can be replenished by replacing the liquid storage barrel 2. A part of the liquid storage barrel 2 is exposed outside the main machine 1, which is also convenient for replacing the liquid storage barrel 2.

[0033] In some embodiments, the liquid storage barrel 2 is not detachable from the main machine 1. The liquid storage barrel 2 is provided with a cover plate. The cleaning agent can be replenished by opening the cover plate.

[0034] The main machine 1 comprises a water storage tank 11, a water inlet pipe 12, and a communication pipe 13. The water inlet pipe 12 communicates an external water source with the water storage tank 11. Water flows into the water storage tank 11 through the water inlet pipe 12. The water storage tank 11 contains water. When the cleaning agent in the liquid storage barrel 2 enters the water storage tank 11, the cleaning agent is diluted.

[0035] The water storage tank 11 is provided with an opening (not shown). The cleaning agent in the liquid storage barrel 2 enters the water storage tank 11 through the opening.

[0036] The communication pipe 13 comprises a first interface 131, a second interface 132, and a third interface 133. The first interface 131 communicates with the water inlet pipe 12. The second interface 132 communicates with the water storage tank 11. The third interface 133 communicates with a washing machine. After the cleaning agent in the liquid storage barrel 2 is diluted in the water storage tank 11, the diluted cleaning agent enters the washing machine through the communication pipe 13, so as to prevent the problem of pipe blockage of the main machine 1 caused by the condensation of concentrated cleaning agent in the fluid pipe or the crystallization caused by the mixing of different cleaning agents.

[0037] The cleaning agent in the liquid storage barrel 2 enters the communication pipe 13. The water flowing through the water inlet pipe 12 enters the communication pipe 13 to flow into the washing machine at the same time as the diluted cleaning agent.

[0038] In some embodiments, the water inlet pipe 12 comprises a first water pipe 121, a second water pipe 122 and a third water pipe 123 connected in sequence.

[0041] The working principle of the Venturi tube is based on the Venturi effect and the law of conservation of energy. When the fluid passes through the convergent section of the Venturi tube, the flow rate increases and the static pressure decreases, thereby generating a pressure difference before and after the throat. This pressure difference is proportional to the flow rate of the fluid, and the flow rate of the fluid can be calculated by measuring this pressure difference. The Venturi tube includes a convergent section, a throat and a divergent section, and the changes of flow rate and pressure when the fluid passes through these sections are used to measure the flow rate.
