[0015] Optionally, the solid water treatment chemical dosing device further includes a second sealing ring, the second sealing ring is arranged at the water inlet of the water tank and is in close contact with the chassis.

[0016] In a second aspect, the present invention provides an application method using the solid water treatment chemical dosing device, which includes the following steps:

[0017] Step S1, adding medicine

[0023] (1) In the solid water treatment chemical dosing device of the present invention, by correspondingly arranging a chemical dosing port on the chassis for each chemical storage tank, and rotating the chassis to enable the chemical dosing port to be communicated with the water inlet of the water tank arranged on the water treatment system pipeline, the problem of dosing in the sealed section of the water treatment system is solved; at the same time, the chemical storage tank is communicated with the water inlet of the water tank through the chemical dosing port, which is convenient for water to flow into the chemical storage tank to dissolve the solid water treatment chemical. After the chemical is dissolved, it then flows into the water to dose the chemical, solving the problem of incomplete dissolution of the solid water treatment chemical; by arranging a plurality of chemical storage tanks circumferentially on the chassis, it is convenient to add different dosages of solid water treatment chemicals into each chemical storage tank according to the water treatment requirements. At the same time, rotate the chassis and use the sliding end of the elastic sliding limit member to enter the limit groove to determine that the chemical dosing port corresponding to the required chemical storage tank is communicated with the water inlet on the water tank. By such operation, the requirements for different dosages of chemicals in multiple dosing cycles are met, greatly improving the dosing efficiency; the size of the chemical dosing port is not larger than the size of the solid water treatment chemical, preventing the chemical from flowing into the water tank in an undissolved state.

[0024] (2) By adopting the application method of the solid water treatment chemical dosing device of the present invention, the required dosage of solid water treatment chemical can be added into each chemical storage tank according to the water treatment requirements of the water treatment system; during the chemical dosing process, it is determined that the chemical dosing port corresponding to the required chemical storage tank is communicated with the water inlet by the sliding end of the elastic sliding limit member entering the limit groove. Specifically, when the sliding end enters the limit groove, it is relatively limited, and at the same time, the elastic member is relatively released from the previous compressed state; at this time, if the handle is rotated further, it will be relatively laborious. Therefore, the present invention can accurately judge whether the chemical dosing port corresponding to the required chemical storage tank is communicated with the water inlet by the force of rotating the handle, thereby realizing accurate chemical dosing. The application method has simple steps and is convenient to operate.

Water flows into the chemical storage tank 3 through the water inlet 1.3 to dissolve the solid water treatment chemicals. After the chemicals are dissolved, they flow into the water through the water inlet 1.3 to dose the chemicals;

[0050] During the process of dosing, the dosing port 2.1 corresponding to the required chemical storage tank 3 is determined to communicate with the water inlet 1.3 by the sliding end of the elastic sliding limiting member entering the limiting groove, and at this time, the rotation of the handle 7 is stopped. Specifically, when the sliding end (i.e., the small ball 5) enters the limiting groove, it is relatively limited, and at the same time, the elastic member 4 is relatively released from the previous compressed state; at this time, if the handle 7 is rotated continuously, it will be relatively laborious.
