Description

Technical Field

[0001] This utility model relates to the field of water purifiers, specifically to a post-filter system and a water purifier. Background Technology

[0002] The post-filter cartridges of a water purifier contain various functional filters. Their function is to receive purified water from the water purifier and, according to user instructions, activate the corresponding functional filter cartridge to treat the purified water in a targeted manner, adding specific functions to the purified water. For example, a mineralizing filter cartridge can increase the mineral content of the water to meet the user's demand for mineral-rich drinking water; a weakly alkaline filter cartridge can improve the body's acid-base balance and has certain health benefits.

[0003] However, current water purifier post-filter cartridges have many problems. Firstly, the wide variety of functional filter cartridges results in extremely complex internal piping layouts. The cartridges are connected by pipes to distribute and transmit water. This complex network of pipes not only increases the overall size of the water purifier and hinders space utilization, but also poses a significant challenge to the rational arrangement of the piping. How to scientifically plan the piping layout within the limited internal space of a water purifier to ensure stable and efficient water flow and avoid problems such as water flow interference and blockages has become a pressing technical challenge.

[0004] Secondly, filter cartridges that have not been used for a long time are prone to bacterial growth and impurity accumulation. If not flushed in time, this will seriously affect the performance of the filter cartridge and thus reduce the quality of the water produced. However, existing flushing methods have drawbacks such as being cumbersome to operate and consuming a lot of water, making it difficult to meet users' needs for convenient and efficient flushing. Developing a simple, easy-to-implement, water-saving, and energy-efficient filter cartridge flushing method is the key to improving the performance of the post-filter cartridges in water purifiers.

[0005] In conclusion, it is necessary to improve the structural design and related technologies of the post-filter cartridge in water purifiers to solve the aforementioned technical problems. Utility Model Content

[0006] To address the above problems, this utility model provides the following technical solution:

[0007] This utility model provides a post-filter system for receiving purified water from a water purifier and outputting purified water with added specified functions. It is characterized by comprising a multi-port connector, a Y-type connector, and one or more functional filter cartridges. The multi-port connector has one inlet and multiple outlets. The inlet of the multi-port connector receives purified water from the water purifier. Each outlet of the multi-port connector is connected to the inlet of a Y-type connector. Each Y-type connector has two outlets connected to a functional filter cartridge. The Y-type connector uses a solenoid valve to control its inlet to connect to 0, 1, or 2 outlets. All functional filter cartridge outlets are connected to a main pipe, which is connected to a water supply port to provide purified water with added specified functions.

[0008] Furthermore, the functional filter element includes one or more of the following: weak alkali filter element, mineralized filter element, selenium-rich filter element, strontium-rich filter element, etc.

[0009] Furthermore, the main pipe is also connected to the wastewater tank, and a reversing valve is installed on the main pipe, allowing it to be connected to either the water supply outlet or the wastewater tank.

[0010] Furthermore, the reversing valve is a solenoid valve.

[0011] The present invention also provides a water purifier that uses the above-mentioned post-filter system to process the purified water in the water purifier into purified water with added specified functions.

[0012] Beneficial effects: The combination of multi-port connectors and Y-type connectors makes the pipeline of the post-filter system more compact, which is conducive to reducing the overall size; at the same time, a connection to the wastewater tank is set at the outlet of the post-filter system, which facilitates the rinsing of the designated functional filter elements in the post-filter system.

[0014] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] like Figure 1As shown, a post-filter system is used to receive purified water from a water purifier and output purified water with added specified functions. It includes a multi-port connector, a Y-type connector, and one or more functional filter cartridges, such as weakly alkaline filters, mineralizing filters, selenium-enriched filters, and strontium-enriched filters. The multi-port connector has one inlet and multiple outlets. The inlet of the multi-port connector receives purified water from the water purifier, and each outlet of the multi-port connector is connected to the inlet of a Y-type connector. Each Y-type connector has two outlets connected to a functional filter cartridge. The Y-type connector uses a solenoid valve to control its inlet to connect to 0, 1, or 2 outlets. All functional filter cartridge outlets are connected to a main pipe, which is connected to a water supply outlet to provide purified water with added specified functions. Through the cooperation of the multi-port connector, Y-type connector, and corresponding solenoid valves, any one or more functional filter cartridges can be selected according to user needs. In a further embodiment, the main pipe is also connected to a wastewater tank, and a solenoid valve is also provided on the main pipe, allowing the main pipe to be connected to either the water supply outlet or the wastewater tank. The system operates normally when the main pipe is connected to the water supply outlet. When the main pipe is connected to the wastewater tank, the designated functional filter cartridges can be flushed. Functional filter cartridges are prone to bacterial growth when not in use for extended periods. Therefore, when the outlet of the combined filter system is connected to the wastewater tank via a solenoid valve, the designated functional filter cartridges can be flushed.

[0016] The post-filter system described in this utility model is more suitable for use in water purifiers with limited internal space, such as hydrogen-rich water purifiers and electrolytic water purifiers, due to its reasonable and compact pipeline layout.

[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
