Description

Inner cavity deodorant toilet

Technical field:

The utility model relates to the technical field of sanitary ware, in particular to an inner cavity deodorizing toilet.

Background technique:

In order to get rid of the bad smell when going to the toilet in the existing bathroom, whether it is a squatting toilet pan or a sitting toilet, an exhaust fan is installed on the wall or ceiling of the bathroom, but the exhaust method of this exhaust fan cannot solve the problem of bad smell. Diffusion problem. Because the exhaust fan is installed on the wall or ceiling, the bad smell first diffuses from the toilet to the entire space of the bathroom, and then is exhausted by the exhaust fan. In this way, the bad smell first diffuses in the bathroom, affecting the cleanliness of the air. There are also essences placed in the bathroom, or air cleaners, but they cannot solve the problem of bad smell diffusion.

Chinese patent No. 200520067844.4 is a utility model patent, which discloses a deodorizing and leak-proof toilet, as shown in Fig. 1. Its main structure includes a toilet seat 101 and a water tank 102. The upper part of the toilet seat 101 is a hollow cavity structure. Also have several water outlet holes 103, a water inlet pipe 104 is connected between the water tank 102 and the upper inner cavity of the toilet seat 101, and a leak-proof water pipe 105 is also arranged inside the water tank 102, and the leak-proof water pipe 105 communicates with the water inlet pipe 104, and prevents The water inlet of the leaking pipe 105 is higher than the water inlet of the water inlet pipe 104, and the water inlet pipe 104 is provided with a three-way pipe 106 between the toilet seat 101 and the water tank 102, and the exhaust pipe 107 is connected with one of the ports of the three-way pipe 106. The water inlet pipe 104 communicates with the inner cavity of the upper part of the toilet seat 101, and the other end of the exhaust pipe 107 is connected to an exhaust fan 108. After the exhaust fan 108 is activated, the odor is discharged to the outside by the exhaust fan 108 through the outlet hole 103 and then through the exhaust pipe 107. Therefore, the odor generated when people go to the toilet will not permeate the toilet, and the effect of deodorization can be achieved. But, as shown in Figure 1, tee pipe 106 is positioned at the rear portion of toilet seat 101, and exhaust pipe 107 is positioned at the rear portion of water tank 102, and the installation space of exhaust pipe 107 must be reserved when toilet is installed, and can damage toilet The wall surface of the existing economical and applicable housing is limited. If a toilet with this structure is used, the floor area of the toilet will be increased, making the bathroom with a relatively small space appear narrower; moreover, the three-way Pipe 106 has been exposed in the wet toilet for a long time, and water leakage occurs at each joint of the three-way pipe 106, which affects the hygienic condition of the toilet.
