Toilet automatic cleaning device

The invention relates to a toilet automatic cleaning device, in particular to a toilet water tank for storing a liquid form of detergent, and mixing or distributing a part of the detergent into the toilet tank every time the toilet flushes. A dispenser in the body of the stored water.

Deodorizing devices or deodorizing methods commonly used in toilets in houses generally include two types. One is to install a ventilating fan on the ceiling or on the wall of the bathroom to discharge the odor to the outside. The second is to place a deodorant in the bathroom to deodorize the deodorant and the odor of the feces. Due to the thermal diffusion characteristics of the air, the odor generated by people after defecation will quickly spread to the entire space of the bathroom or even other spaces, and the odor generated by the sewage left by the toilet sewer will diffuse into the space at any time. Both of these deodorization methods can only work if the fecal odor spreads to a certain extent. Before they take effect, the user or other personnel have to endure the infestation of fecal odor for a period of time. Therefore, timely removal of fecal odor generated after defecation can reduce the odor infestation.

Adapted to this need, solid form toilet cleaners have appeared on the market. When in use, the solid detergent is placed in the toilet tank and allowed to slowly dissolve in the water. The fragrance dissolved in the water gives off an aromatic odor that neutralizes the odor of the stool. After the user has finished defecation, the water in the water tank is filled into the toilet, and a protective film formed on the inner wall of the toilet by the cleaning agent prevents the adhesion of dirt, urine, feces, etc. on the inner wall of the toilet, and maintains The effect of the toilet cleaning. At the same time, part of the water body remaining in the toilet contains the detergent, so that the urine and feces discharged into the toilet will be integrated into the water body in time, and the odor generated by the urine and the feces can be largely obtained. Timely neutralization greatly eases the degree of odor and disturbance.

However, since the solid detergent is in a continuous dissolution process after being placed in the toilet tank, until the dissolution is completed. Therefore, the solid detergent will be dissolved in a certain period of time regardless of whether the flushing action occurs during the dissolution period of the solid detergent. In other words, the number of flushes is independent of the service life of the detergent. When the toilet is not used for a long time, since the solid detergent is mostly in a liquid state after being dissolved for a long time, the content in the water body is high, and finally the amount of the detergent is excessively used, resulting in waste. On the other hand, when the toilet is used frequently, The flushing interval of the toilet is shortened, resulting in a low level of detergent in the water body, even down to a point where the effect is very weak, so that it is difficult to form a sufficient protective film on the inner wall of the toilet to prevent the dirt from adhering and the fragrance emitted. The smell is not enough to offset the smell of feces. Solid detergents are difficult to control the amount of each use during use, resulting in high and low concentrations of detergent in the toilet tank. When the concentration is low, the cleaning effect is poor, and when the concentration is high, unnecessary waste is formed.
