Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a household ozone sterilization water purifier. Background Technology
[0002] According to the "Household Water Hygiene Survey Report" released by the Chinese Center for Disease Control and Prevention in 2023, microbial contamination of non-drinking water in households (such as washing vegetables, washing hands, and cleaning) is particularly prominent. In particular, the washing of raw meat and rinsing of cutting boards in the kitchen are prone to cross-contamination, and long-term use of traditional chemical disinfectants may induce allergic dermatitis. Therefore, sterilization treatment of domestic water is an urgent problem to be solved.
[0003] Currently, traditional household water purifiers only provide drinking water and cannot meet the sterilization needs of daily water use (such as washing fruits and vegetables, tableware, and washing hands). If ordinary ozone water purifiers are used in combination with RO systems, there are potential safety hazards such as ozone infiltration and pollution of the drinking water circuit and excessive bromate levels.
[0004] Therefore, we propose a household ozone sterilization water purifier to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a household ozone sterilization water purifier to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A household ozone sterilization water purifier includes a shell, a main inlet pipe, a direct drinking water branch, and a domestic water branch. The shell is divided into a pre-filter chamber, an RO membrane chamber, and an ozone chamber by horizontal and vertical partitions. The pre-filter chamber contains a PP cotton filter and a pre-activated carbon filter connected in sequence, and the main inlet pipe is connected to the inlet end of the PP cotton filter. The direct drinking water branch and the domestic water branch are connected to the outlet end of the pre-activated carbon filter via pipes and three-way valves. The direct drinking water branch includes a high-pressure pump, an RO membrane filter, and a post-activated carbon filter connected in sequence. A wastewater inlet pipe is connected to the RO membrane filter, and a direct drinking water inlet pipe is connected to the post-activated carbon filter. The domestic water branch includes a sterilization cartridge and an ozone generator, connected by a Venturi jet injector. The outlet end of the sterilization cartridge is also connected to the domestic water inlet.
[0008] In a further embodiment, the main inlet water pipe, wastewater pipe, drinking water pipe, and domestic water pipe all extend through the back plate of the housing.
[0009] In a further embodiment, a one-way valve is installed in the inlet pipe of the domestic water branch.
[0010] In a further embodiment, spiral guide vanes are evenly distributed circumferentially on the inner wall of the sterilization cylinder.
[0011] In a further embodiment, a concentration sensor is installed inside the water outlet pipe of the sterilization cartridge, and an intelligent controller is also installed inside the housing.
[0012] In a further embodiment, a safety secondary pipe is also installed on the external water supply pipe via an electromagnetic reversing valve, and the inner wall of the safety secondary pipe is coated with a nano-manganese dioxide catalyst.
[0013] In a further embodiment, the ozone generator is completely sealed within the ozone chamber, and the ozone chamber and the RO membrane chamber are completely independently sealed.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention features two independent water channels: a direct drinking water channel and a domestic water channel. The domestic water is treated with ozone to remove microorganisms, ensuring both safety and effectiveness. The direct drinking water undergoes deep RO purification, meeting national drinking water standards. Both channels are initially filtered through PP cotton and activated carbon, and the separate chamber design completely blocks ozone gas from penetrating into the RO channel, avoiding the risk of bromate contamination. Furthermore, the domestic water channel does not require a high-pressure pump or RO membrane, reducing energy consumption and filter replacement costs. Attached Figure Description

[0024] Please see Figure 1-4A household ozone sterilization water purifier includes a shell 1, a main inlet pipe 2, a direct drinking water branch line 7, and a domestic water branch line 8. The shell 1 is divided into a pre-filter chamber, an RO membrane chamber, and an ozone chamber by horizontal partitions 3 and vertical partitions 4. A PP cotton filter element 5 and a pre-activated carbon filter element 6 are installed in the pre-filter chamber and connected sequentially by pipes. The main inlet pipe 2 is connected to the inlet end of the PP cotton filter element 5. The direct drinking water branch line 7 and the domestic water branch line 8 are connected to the outlet end of the pre-activated carbon filter element 6 via pipes and three-way valves. The direct drinking water branch line 7 is installed in the RO membrane chamber. Inside the RO membrane chamber, the domestic water branch 8 is installed inside the ozone chamber. The pipes are sealed when they pass through the partition or outer shell to ensure that the ozone chamber and the RO membrane chamber are completely independent and sealed. The drinking water branch 7 includes a high-pressure pump 9, an RO membrane filter 10 and a post-activated carbon filter 11 connected in sequence through pipes. The RO membrane filter 10 is also connected to a wastewater external pipe 12, which is used to connect to an external waste discharge pipe. The post-activated carbon filter 11 is also connected to a drinking water external pipe 13, which is used to connect to an external drinking water faucet.
[0025] The domestic water branch line 8 includes a sterilization cylinder 14 and an ozone generator 15. A one-way valve 81 is installed in the inlet pipe of the domestic water branch line 8 to prevent the backflow of water mixed with ozone and contamination of the direct drinking water branch line 7. The ozone generator 15 is a high-voltage discharge generator that converts oxygen in the air into ozone. The sterilization cylinder 14 is connected to the branch pipe, and the output end of the ozone generator 15 is connected to the sterilization cylinder 14 through a Venturi jet injector 16. Specifically, the connection end between the Venturi jet injector 16 and the sterilization cylinder 14 is also equipped with an anti-backflow valve. To prevent liquid contamination of the ozone generator 15, ozone is introduced into the sterilization cylinder 14. Spiral guide vanes 141 are evenly distributed circumferentially on the inner wall of the sterilization cylinder 14 to form turbulence, which facilitates the mixing of water and ozone. The water outlet of the sterilization cylinder 14 is also connected to a domestic water external pipe 17, which is used to connect to a domestic water tap. Specifically, the main water inlet external pipe 2, the wastewater external pipe 12, the direct drinking water external pipe 13, and the domestic water external pipe 17 all protrude through the back plate of the housing 1, which facilitates their connection to other components.
[0026] To enhance safety, a concentration sensor 18 is installed inside the outlet pipe of the sterilization cartridge 14, and an intelligent controller 19 is also installed inside the housing 1. According to existing technology, the ozone output concentration range for the safe disinfection of domestic water is 0.5-2 mg / L. When the concentration sensor 18 detects that the ozone in the water is less than 0.5 mg / L, the intelligent controller 19 adjusts the power of the ozone generator 15 through a PID algorithm to ensure that the concentration remains stable within the safe and effective range of 0.5-2 mg / L. A safety secondary pipe 21 is also installed on the domestic water external connection 17 via an electromagnetic reversing valve 20. The other end of the safety secondary pipe 21 is connected to the outlet end of the domestic water external connection 17, and the inner wall of the safety secondary pipe 21 is coated with a nano-manganese dioxide catalyst. When the concentration sensor 18 detects that the ozone in the water is greater than 2.5 mg / L, the intelligent controller 19 controls the ozone generator 15 to shut off and simultaneously controls the electromagnetic reversing valve 20 to switch, allowing domestic water to flow through the safety secondary pipe 21. The nano-manganese dioxide catalyst can accelerate the decomposition of excess ozone.
