Description

A toilet self-cleaning device

technical field

The utility model relates to a toilet self-cleaning device, in particular to a toilet cleaning agent that is automatically sucked into a water tank by the high-speed water flow when the toilet enters the water, so that the water in the water tank contains cleaning ingredients, and realizes disinfection and cleaning when the toilet is flushed. .

Background technique

Due to the growth of bacteria, the inner surface of the toilet will become dirty after three to five days of use and need to be cleaned. If manual cleaning is used every time, it not only needs manpower, but also consumes a large amount of toilet cleaner and water. For this reason, need a kind of not only can save manpower, but also the toilet self-cleaning device of energy-conserving resources on the market.

In order to save manpower and material resources, there are solid toilet cleaning agents such as toilet cleaning balls, toilet cleaning spirits, and cleaning balls on the market. When in use, it is put into the toilet water tank, and the external water film of the solid toilet cleaner is used to slowly infiltrate the detergent into the water, so that the water in the water tank contains cleaning ingredients, and the toilet is disinfected and cleaned when flushing. However, this method has several disadvantages: one is that when the frequency of use of the toilet is low, the concentration of the lavatory agent in the water tank is too high, and the water is very blue during flushing; The color of the water is only a little blue at the time, and the sterilization effect is poor; the second is that the toilet tank cover needs to be opened every time the fixed toilet cleaner is replaced, which is very troublesome, and the bottle cap of the water tank will be broken if you are not careful; When it is finished, the water film will be broken, and it will easily adhere to the inner wall of the toilet when it flows out. It needs to be rinsed with additional water. Sometimes the adhesion is too tight and needs to be removed manually. Combining these shortcomings, coupled with the uneven quality of solid toilet cleaners of various brands, the user experience is relatively poor, resulting in a low market penetration rate.

In order to eliminate the shortcomings of direct dosing of solid detergents, some utility models have been developed, such as: a toilet self-cleaning device (patent number CN201510060392.5), a toilet cleaner adding device (patent number CN201520566867.3) , a toilet cleaning device (patent number CN201320529001.6), etc. These devices only control the amount of cleaning agent added, or change the method of adding, but all have some disadvantages: the first is troublesome installation or debugging; the second is that after the cleaning agent is used up, it is still necessary to open the toilet tank cover to add; The manufacturing cost is relatively high; the fourth is that the device is relatively large, which occupies the volume of the water tank and reduces the amount of flushing water. It may be necessary to increase the number of flushing, but instead consumes water resources (the amount of flushing water in the current design is optimized for water saving. If the amount of flushing water If you reduce it too much, the toilet will not be flushed clean once).

In view of the above situation and usage requirements, the utility model designs a toilet self-cleaning device, which has no waste of toilet cleaning agent, is easy to install and use, and does not have too much or too small concentration of toilet cleaning agent, and does not need to open the toilet tank to add toilet cleaning agent The lid has advantages such as low manufacturing cost, is very suitable for toilet cleaning in various occasions, and can be widely promoted.
