Publication number: 20220389698Abstract: A smart deodorization device with a cover plate includes a reaction chamber having a reaction cavity; an air extraction unit, configured for extracting odor in or near a toilet pool into the reaction cavity; and a water supply unit, configured for supplying water to the reaction cavity. When working, the air extraction unit extracts the odor into the reaction cavity, and the odor is mixed with the water in the reaction cavity to be converted into purified gas and then discharged from the reaction cavity. By using the characteristic that ammonia molecules in the odor are easily soluble in water, the odor and water are mixed in the reaction cavity and then discharged to realize the gas purification. Thus, the device has obvious effects, simple structures, lower costs, and convenience to use without need of replacing filtering materials.Type: ApplicationFiled: August 6, 2020Publication date: December 8, 2022Applicant: XIAMEN R&T PLUMBING TECHNOLOGY CO., LTD.Inventors: Zhipeng LIU, Jian LIN, Zhaoxing LAN, Zhijun ZHONG

Patent number: 9790675Abstract: A double flow control mechanism of a soft touch drain valve and a double flow control method, includes a base, a float component and a starting component. The base is assembled with a valve body. The float component is has a flowing passage and can move relative to the base to open and close the drainage opening. The flowing passage connects the inside and the outside of the float chamber of the float component. The starting component controls the size of the flowing passage. The first starting switch can open a smaller flowing passage of the float component; the resultant force drains a first drainage volume of water. The second starting switch can open a larger flowing passage of the float component; the resultant force drains a second drainage volume of water.Type: GrantFiled: November 18, 2015Date of Patent: October 17, 2017Assignee: XIAMEN R&T PLUMBING TECHNOLOGY CO., LTD.Inventors: Haibin Chen, Rongyu Zhang, Zhijun Zhong, Ruiliang Chen

Patent number: 9709190Abstract: A height adjusting mechanism for an inlet valve includes a valve body, and inlet pipe, a retaining member and an actuator. The inlet pipe is sleeved in the valve body and connected to the valve body; the retaining member is assembled in the valve body; and the actuator can drive the retaining member to move to make the valve body fixed to the inlet pipe or moved relatively to the inlet pipe in the axial direction. The actuator drives the retaining member to move in order to let the valve body and the inlet pipe to be fixed or moved relatively to each other in the axial direction. There is no need to rotate the valve body during adjusting process, and the float won't affect the tank wall when the water valve body is rotating.Type: GrantFiled: March 6, 2013Date of Patent: July 18, 2017Assignee: XIAMEN R&T PLUMBING TECHNOLOGY CO., LTD.Inventors: Guiyang Huang, Zhijun Zhong, Bing Wang
