Description

Technical Field

[0001] The utility model relates to a descaling and liquid adding box for an intelligent toilet. Background Art

[0002] The cleaning function of an intelligent toilet uses water heating technology, which easily causes precipitation of minerals such as calcium and magnesium in the water, and scale is formed over time. Scale not only affects the beauty of the toilet, but also blocks the nozzle or affects the water flow intensity, thus reducing the user experience. Therefore, some intelligent toilets are equipped with a descaling function to remove the scale attached to the internal pipes or nozzles, maintain the normal operation and optimal performance of the toilet, and also help to extend the service life of the toilet. Moreover, regularly removing scale can reduce the risk of equipment failure caused by scale accumulation, thus ensuring the long-term stable operation of the intelligent toilet. At present, when starting the descaling function of the intelligent toilets on the market, in addition to adding descaling liquid, it is necessary to press the operation switch at least twice. First, press the corresponding button to start the descaling function for draining water, then add the descaling liquid, and then press the corresponding button to start the descaling function for the second time for descaling, that is, the customer needs to press the corresponding descaling switch separately, which is likely to cause customers to neglect and increase inconvenient operations for customers.

[0014] Compared with the background technology, this technical solution has the following advantages:

[0015] 1. When the drawer cover is opened, the operating lever touches the micro switch, and the micro switch sends a command to start the water discharge function of the water tank to the intelligent toilet control system, emptying the water in the water tank. When the drawer cover is closed, the operating lever touches the micro switch again, and the micro switch sends a descaling function command to the intelligent toilet control system, thereby starting the descaling function of the intelligent toilet. Therefore, during the liquid adding process, the operating lever touches the micro switch as the drawer cover moves, enabling the intelligent toilet to start the descaling function. The operator does not need to operate the micro switch separately other than adding liquid, simplifying the descaling operation and avoiding the situation where the operator forgets to press the micro switch.

[0016] 2. The sealing ring can prevent the descaling liquid from leaking out along the gap between the box body and the drawer cover. Especially when two sealing rings are used, the two sealing rings are respectively located in front of and behind the liquid outlet in the initial state, and can prevent the liquid in the liquid outlet from flowing back reversely into the drawer cover.
