摘要： A foaming device comprises a valve body, a pump, and a self-suction spray head. The valve body comprises a water inlet port, a liquid inlet port, a mixing cavity, and a liquid outlet port. Each of the water inlet port, the liquid inlet port, and the liquid outlet port is in communication with the mixing cavity, and an input end of the pump is connected to the liquid outlet port to enable the mixing cavity to generate a negative pressure to suck water and foaming agent respectively from the water inlet port and the liquid inlet port for mixing. The self-suction spray head is connected to an output end of the pump, and the self-suction spray head comprises a first air inlet hole and a spray hole to enable mixed liquid to be mixed with air to produce foam to be sprayed out.

摘要： A toilet pan is provided with a water replenishing device for flush rim with silence function. The water replenishing device has independent drainage from the drainage of the cisterns. The water replenishing device includes a water storage box with a water inlet on top side and a drainage outlet on bottom side. The drainage outlet is connected to the waterway for flush rim. A lid is installed in the water storage box to open or close the drainage outlet. The water storage box is provided with a water storage area. A back flow channel has one end connected to the water inlet and the other end extending into the water storage area below or equal to the highest level of the water storage area. Such toilet makes less noise by eliminating water inlet noise.

摘要： A spray washing component for a smart toilet cover and an assembly method thereof are provided. The spray washing component includes a base, a nozzle, and a first motor. A sliding track is disposed on the base. The nozzle has a rack cooperating with the first motor. The first motor drives the nozzle to slide along the base. The first motor is installed at an end away from a jet of the nozzle and drives the nozzle to be displaced through a transmission structure. The transmission structure includes a driving gear, a dual transmission gear, and a conveyor belt. The driving gear is in anti-rotation cooperation with an output shaft of the first motor. The dual transmission gear respectively meshes with the conveyor belt and the rack on the nozzle. The spray washing component and the assembly method solve the large space occupation and insufficient aesthetics of the existing toilet.
