Method and device for automatically sterilizing and cleaning pedestal pan

Abstract

The invention provides a method and a device for automatically sterilizing and cleaning a pedestal pan. The method at least comprises the following steps of: providing the pedestal pan, an electric control device, a sensor, a switching valve, a front water pipe, an ozone device and a rear water pipe, wherein one part of the rear water pipe is higher than the ozone device, the electric control device is connected with the sensor, the ozone device and the switching valve, and the water flow is communicated with the ozone device and the rear water pipe through the switching valve and the front water pipe and reaches the pedestal pan when the switching valve is opened; when the sensor detects that a user is close to the pedestal pan, performing flushing of a first stage; when the sensor detects that the user leaves the pedestal pan, performing flushing of a second stage, wherein the ozone device generates ozone water to flush the pedestal pan; and finally, closing the switching valve by the electric control device in the predetermined time. Other agents are not needed in the device, and only a little ozone is dissipated to the air so that possible human body discomfort caused by gaseous ozone can be avoided.

Description

technical field [0001] The invention provides a toilet disinfection and deodorization system and method, especially refers to the use of ozone's sterilization and deodorization capabilities to maintain the cleanliness of the environment and individuals. Background technique [0002] Maintaining the cleanliness and sanitation of the bathroom and toilet environment is actually the basic requirement of modern people for the quality of living. In particular, various pathogens such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus, mold, pyogenic bacteria, white moss and mold often lurk in the toilet, which may cause various allergic diseases to toilet users. [0003] figure 1 A schematic showing an existing automatic flushing device. See figure 1 . An automatic flushing device used in a general bathroom and toilet may include an electric control device 102 , a sensor 104 , a switch valve 106 , a water source 108 , a urinal 110 and a power supply 114 . The electric...

Problems solved by technology

However, as can be seen from the device of this patent, the ozone device 1 produces ozone through pipelines such as the air inlet pipe 32, the ozone mixer 3, the water delivery pipe 31 and the immersion pump 2.

However, the mixing process of the patented water and ozone is very short, and most of the ozone is too late to dissolve and exists in the water in the form of bubbles. This gaseous ozone will be released into the ambient air in large quantities during the flushing process, causing serious damage to human health. threaten
