An integrated structure for a water purification tank with built-in filtration components

Abstract

This utility model relates to an integrated structure for a water purification tank with a built-in filter assembly. It includes a water purification tank body, a water inlet assembly, a filter bottle inserted into the inner wall of the water purification tank from top to bottom, a filter element embedded in the filter bottle, a bottle cap that seals with the top opening of the filter bottle, and a tank cap that seals the top opening of the water purification tank body. The filter bottle is inserted into the water purification tank, and a raw water filter port and a push pad are respectively provided on the outer wall. A sealing ring is provided on the end face of the raw water filter port. The filter bottle is open at the top and contains a filter element. The center of the filter element is the filtered area, and a purified water outlet is provided below the filtered area. This structure significantly reduces the space required for fixing the filter bottle and reduces the number of connectors and pipe connections. When installing or replacing the filter element, simply rotate the filter element to remove it. Raw water enters the post-activated carbon filter element through the side inlet and flows directly into the lower water purification tank after passing through the filter element. This simplifies the installation process. The filter element is integrated inside the water purification tank, and the filter element outlet flows directly into the water purification tank, saving space.

Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, specifically to an integrated structure for a water purifier tank with built-in filter components. Background Technology

[0002] With increasing health awareness and the maturation of water purifier technology, countertop water purifiers and heaters have entered the market and are gaining a growing market share, bringing great convenience to people's drinking water. To improve the intelligence and miniaturization of these integrated water purifiers, higher requirements have been placed on their reliability and size. In the context of intense competition in the small appliance market, water purifiers with comprehensive functions, stable quality, small size, and low cost will be more competitive. From a product design and development perspective, the water circuit structure of these products must also become simpler.

[0003] Traditional post-filter installation involves mounting a separate filter bottle onto a mounting base, with piping connected to the water tank. This design occupies significant space, making it difficult to meet the miniaturized needs of customers. If the space occupied by the filter unit could be saved and combined with the space within the water tank, the space required for piping and filtration would be greatly reduced, improving space utilization. Therefore, it is necessary to design a filtration assembly built into the water tank. Utility Model Content

[0004] The purpose of this invention is to propose a filter assembly built into a water purification tank. This assembly allows the water purification tank and filter bottle to be stacked together, and an activated carbon filter element is installed. The purified water, after passing through the filter element, can directly enter the water purification tank after passing through a post-filter element. This eliminates the need for a filter bottle shell, reduces the number of pipe connections between the filter bottle and its fixing base and the water purification tank, reduces potential leakage points, improves quality stability, avoids wasted space, and saves costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated structure for a water purification tank with a built-in filter assembly includes a water purification tank body, a water inlet assembly, a filter bottle filled from top to bottom into the inner wall of the water purification tank, a filter element built into the filter bottle, a bottle cap that seals with the top opening of the filter bottle, and a tank cover that seals the top opening of the water purification tank body.

[0007] The water purification tank has an inlet on its side wall and an outlet at its bottom. The inlet works with the inlet assembly to obtain raw water. The inner wall of the inlet has a sealing ring groove that fits snugly against the raw water filter port on the side wall of the filter bottle.

[0008] The water inlet assembly includes an inlet connector, an inlet pipe, and a booster pump. The booster pump pumps water into the inlet pipe, drawing raw water into the purified water tank. The inlet connector provides a sealed connection between the inlet pipe and the inlet.

[0009] The filter bottle is filled into the water purification tank, and a raw water filter port and a push pad are respectively provided on the outer side wall. The end face of the raw water filter port is provided with a sealing ring. The sealing ring is positioned and sealed tightly with the sealing ring groove. The push pad is radially aligned and tightly attached to the inner wall of the water purification tank, so that the overall structure of the filter bottle is coaxially arranged with the water purification tank. The filter bottle is open at the top and has a filter element inside. The center of the filter element is the filtered area. A purified water outlet is provided below the filtered area. The purified water outlet releases the filtered purified water into the purified water storage area below. The purified water is supplied to the outside for drinking through the water outlet at the bottom of the water purification tank.

[0010] Furthermore, the bottle cap is provided with a positioning handle at the top, and its outer peripheral sidewall is fitted to the inner wall of the filter bottle and screwed shut to ensure stable internal air and water pressure and prevent liquid leakage.

[0011] Furthermore, the tank cover includes a wrench at the upper end, a cover plate at the lower end, and an outer sealing ring. The outer sealing ring is provided with a sealing strip and fits snugly against the inner wall of the water tank for a tight seal.

[0012] Compared with the prior art, the present invention, by adopting the above technical solution, has the following technical effects:

[0013] 1. The integrated structure of the water tank with built-in filter components greatly reduces the space required for fixing the filter bottles and reduces the number of joints and pipe connections, making the water circuit simpler. The modular design allows for easy installation and replacement of the filter cartridge by simply rotating it out. Raw water enters the post-activated carbon filter cartridge through the side inlet and flows directly into the water tank below after passing through the filter cartridge, greatly simplifying the installation process and reducing installation difficulty.

[0014] 2. The traditional method of installing a post-filter cartridge involves installing a separate filter bottle onto a mounting base, which is then connected to the inside of the water tank via a pipe on the mounting base. This structure eliminates the mounting base and pipe, allowing water to enter directly through the side inlet, thus reducing the problem of missing or under-installed filters.

[0015] 3. The filter element is integrated inside the water purification tank, making it compact in size. The water from the filter element outlet flows directly into the water purification tank, saving space and featuring a compact structural design.

[0016] 4. This integrated water tank structure allows water to enter from the side inlet, unlike the traditional bottom inlet, so the length of the filter cartridge and filter bottle can be adjusted independently and is no longer restricted. Attached Figure Description
