Description

Technical Field

[0001] The utility model relates to a pre-filtering device for purifying water. Background Art

[0002] The pre-filters currently available on the market generally only achieve simple physical filtration and have a single function. Different water sources have different water quality conditions, which puts forward different requirements for pre-filters. Moreover, the uses of filtered water are different, such as drinking, watering flowers, washing clothes, etc., which also require some corresponding changes to the pre-filters. Obviously, the existing products on the market are difficult to meet the actual diversified needs. On the other hand, the existing pre-filters are inconvenient to disassemble, clean and maintain, the maintenance cost is high, and the water purification effect needs to be further improved. Summary of the invention

[0003] In view of the shortcomings existing in the above problems, the utility model provides a pre-water purification filter device.

[0004] To achieve the above-mentioned purpose, the utility model provides a pre-water purification filter device, comprising a first filter unit, a second filter unit and a pipe joint connecting the two to form an integral body, the first filter unit comprising a first cylinder, a first upper cover screwed on the first cylinder by a thread, and a first filter element arranged in the first cylinder, the second filter unit comprising a second cylinder, a second upper cover screwed on the second cylinder by a thread, and a second filter element arranged in the second cylinder, the first filter element comprising an upper filter and a lower filter that are plugged in, the upper filter comprising a filter body having a cavity, a pressure cover pressed on the filter body, fine filter holes are processed on the annular surface of the filter body, a water through hole is processed on the pressure cover, and the water through hole enables the cavity to be connected with the water inlet of the first upper cover;

[0005] When in use, water enters the cavity through the water inlet of the first upper cover and is fully in contact with the contents in the cavity before being filtered out through the filter body. Afterwards, the initially filtered water is secondary filtered by the lower filter and then sequentially passes through the water outlet of the first upper cover and the pipe joint to the second filter unit, and is filtered three times by the second filter element.

[0006] Furthermore, sealing gaskets are disposed at the joint surfaces between the first cylinder and the first upper cover, and between the second cylinder and the second upper cover.

[0007] Furthermore, an annular magnet is placed in the cavity.

[0008] Furthermore, the content stored in the cavity is activated carbon.

[0009] Furthermore, the filter body is made of stainless steel, and the lower filter and the second filter element are both ceramic filter elements.

[0010] Furthermore, the first cylinder and the second cylinder are made of transparent material.

[0011] The beneficial effects of the utility model compared with the prior art are:

[0012] 1. The cylinder body and the upper cover are threaded, which makes disassembly and maintenance convenient and has low maintenance cost.

[0013] 2. The device can perform three physical filtrations, with metal filters and ceramic filter elements for targeted impurity removal, and has a good filtration effect. The metal filter is made of stainless steel or other corrosion-resistant metals, which can effectively filter out larger particles and impurities. The ceramic filter element uses the microporous structure of ceramic materials to filter out smaller particles and impurities while maintaining the taste and nutrients of the water.

[0014] 3. Different water purifiers can be placed in the cavity of the upper filter as needed. Selection can be made based on the actual water source conditions to meet actual needs.

[0015] 4. A ring-shaped magnet is placed in the cavity of the upper filter, which can absorb and store more ferromagnetic impurities.

[0016] 5. The cylinder is made of transparent materials such as glass or transparent plastic, so the filter element loss can be seen visually with the naked eye. BRIEF DESCRIPTION OF THE DRAWINGS
