Description

Technical Field

[0001] The present invention relates to the technical field of toilet water channels, and in particular to an intelligent toilet water channel silver ion cleaning device. Background Art

[0002] As a core device in modern bathrooms, the cleanliness and antibacterial capabilities of the smart toilet's water system are directly related to the user's health experience. With consumers' increasing demands for bathroom cleanliness, especially concerns about the risk of cross-infection (such as E. coli and Staphylococcus aureus), traditional water system designs that rely solely on physical flushing or chemical disinfection are no longer able to meet these needs. For example, in humid environments, bacteria easily grow on the inner walls of water channels. Long-term contact with scale and microorganisms on components such as nozzles and pipes can lead to secondary contamination of the cleaning water and even cause skin or urinary tract infections.

[0003] As a broad-spectrum antibacterial agent, silver ions have gradually become an ideal choice for cleaning smart toilet water channels due to their non-antibiotic properties, long-term antibacterial ability and safety. By embedding silver ion materials in key water channel components (such as nozzles and pipes), continuous destruction of bacterial biofilms can be achieved, inhibiting microbial reproduction, while avoiding water pollution by chemical disinfectants. To this end, a smart toilet water channel silver ion cleaning device is now provided to solve the above problems. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) The smart toilet waterway silver ion cleaning device is designed with a spiral channel component, a silver ion chamber and a silver ion ceramic ball. A spiral diversion channel is set in the waterway, and the end is connected to a friction chamber containing a silver ion ceramic ball. When water flows through the spiral channel, centrifugal force is generated, which drives the ceramic ball to rotate at high speed, and the friction releases silver ions into the water. The greater the flow rate, the higher the friction intensity. The silver ion release amount is adaptively adjusted to avoid excessive waste. Fluid mechanics is used to achieve pure mechanical slow release, avoiding dependence on electricity or intelligent systems. In addition, the anti-wear positioning component is set. When the water flow pressure increases, the pin is compressed and retracted, and the contact pressure of the ceramic ball is reduced to avoid excessive wear. When the pressure decreases, the spring returns to increase the contact pressure to maintain the basic release amount. The honeycomb structure of the silver ion ceramic ball increases the specific surface area, and the rare earth element improves the wear resistance. The silver ion release cycle is extended to 6-8 months.

[0016] (2) The silver ion cleaning device for the water channel of the smart toilet can clean the surface of the silver ion ceramic ball through the setting of the self-cleaning module, so as to avoid the clogging of impurities adhering to the silver ion ceramic ball and affecting the efficiency and quality of silver ion release and water purification. The driving mode still relies on water flow, which reduces the manufacturing and operation costs and reduces the inspection and maintenance costs. In addition, the setting of the UV sterilization module uses UV to sterilize and disinfect the water channel and device components, further improving the water channel purification quality. At the same time, with the setting of the filter component, it can intercept and filter impurities in the water channel to prevent scale, which is conducive to promotion and use.
