Description

Technical Field

[0001] The utility model mainly relates to the technical field of water purification filter elements, and in particular to a durable filter element for removing metal particles. Background Art

[0002] A water filter cartridge is a component used to purify water, typically found in water purifiers or filter pitchers. They are typically made of various materials, such as activated carbon, ceramic, and cellulose. They filter impurities, odors, harmful substances, and microorganisms from the water, providing cleaner, healthier drinking water. Different types of filters target different pollutants, such as heavy metals, residual chlorine, and bacteria and viruses.

[0003] In some areas, domestic water is transported through iron pipes. When the iron ions in the water come into contact with the metal surface inside the pipes, they react with oxygen to produce oxides, namely rust. If the groundwater used has a high iron content and the water quality is not adequately treated, long-term contact and accumulation with the water pipes will cause rust to appear inside the pipes. In order to ensure healthy water use, some families will use purification filters to preliminarily filter the tap water before use.

[0004] If there are too many rust metal particles in the water pipe, the accumulation of rust particles will accelerate the aging and damage of the filter element, increase the frequency of filter element replacement, and increase the cost of maintenance and replacement of the filter element; a large amount of rust particles may damage the structure of the filter element, causing the filter element to deform, rupture or damage, thereby affecting the service life and filtering effect of the filter element; a large amount of rust particles will clog the micropores of the filter element, reduce the flow of water, or even completely block the passage of water, causing the filter element to fail.

[0005] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 1. Technical problems to be solved by the utility model:

[0007] The utility model provides a durable filter element for removing metal particles, which is used to solve the technical problems existing in the above-mentioned background technology.

[0008] 2. Technical solution:

[0009] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a durable filter element for removing metal particles, including a filter cartridge, the top of which is detachably connected to a feed cover, the feed cover is provided with a water inlet pipe, the outside of the filter cartridge is slidably connected to a magnetic suction cartridge, the bottom of the filter cartridge is connected to a sealing cover, the top of the sealing cover is connected to a filter element, and an outlet pipe is provided in the middle of the bottom surface of the filter element to connect to the sealing cover. The filter element of this device adopts conventional technology, which will not be elaborated here. When this device is working, the water inlet pipe is connected to the water inlet end of the water pipe. After the tap water passes through the external space formed by the filter element and the filter cartridge, it enters the outlet pipe along the filter element for filtration and discharge. In this process, the external magnetic cylinder will adsorb magnetic metals such as iron filings on the inner wall of the filter cartridge. After using it for a period of time, the feed cover is opened and turned upside down, and the outer magnetic cylinder is pulled out. Under the action of gravity, the metal particles that have lost magnetic adsorption are discharged downward, and the feed cover can be sealed again. This device can adsorb magnetic substances in the water to the side wall of the filter cartridge, filter the magnetic metal, and increase the service life of the internal filter element. The metal removal operation is simple, practical and convenient.

[0010] Furthermore, the inside of the filter cartridge is slidably connected to an annular filter scraper, and the top of the annular filter scraper is connected to a concave support handle.

[0011] Furthermore, sliding blocks are symmetrically provided on the outside of the annular filter scraper, and sliding grooves are symmetrically provided inside the filter cylinder, and the sliding blocks are matched and connected to the sliding grooves.

[0012] Furthermore, the magnetic suction cylinder includes an annular cover, and arc-shaped magnets are bonded to the outside of the annular cover at intervals.

[0013] Furthermore, the inner side of the feed cover is provided with a thread, the outer side of the top of the filter cartridge is provided with a thread, and the feed cover is threadedly connected to the filter cartridge.

[0014] 3.Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0016] The utility model has a reasonable design and a compact overall structure. When used in areas with serious magnetic metal pollution, it is only necessary to open the feed cover and pull out the magnetic suction cylinder to clean the adsorbed magnetic impurities at regular intervals. The operation is simple and there is no need to replace the entire filter device due to the accumulation of magnetic metals. The utility model can well protect the internal filter element and increase its service life.

[0017] An annular filter scraper is provided to scrape off the magnetic metal adhering to the inner wall and improve the subsequent adsorption effect of the device.

[0018] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and are the same as the existing technology or can be implemented by using the existing technology, so they will not be described in detail here.

The filter element 6 of this device adopts conventional technology, which will not be elaborated here. When this device is working, the water inlet pipe 3 is connected to the water inlet end of the water pipe. After the tap water passes through the external space formed by the filter element 6 and the filter cartridge 1, it enters the water outlet pipe 7 along the filter element 6 for filtration and discharge. In this process, the external magnetic suction cylinder 4 will adsorb magnetic metals such as iron filings on the inner wall of the filter cartridge 1. After using it for a period of time, the feed cover 2 is opened and turned upside down, and the outer magnetic suction cylinder 4 is pulled out. Under the action of gravity, the metal particles that have lost magnetic adsorption are discharged downward, and the feed cover 2 can be sealed again. This device can adsorb magnetic substances in the water to the side wall of the filter cartridge 1, filter the magnetic metal, and increase the service life of the internal filter element 6. The metal removal operation is simple, practical and convenient.

[0029] The filter cartridge 1 is internally slidably connected to an annular filter scraper 11, and the top of the annular filter scraper 11 is connected to a concave support handle 12. Under the action of gravity, most of the magnetic metal will fall off, but some of the magnetic metal will stick to the inner wall of the filter cartridge 1.

[0030] The annular filter scraper 11 is symmetrically provided with a sliding block 13 on the outside, and the filter cartridge 1 is symmetrically provided with a sliding groove 14. The sliding block 13 is matched and connected to the sliding groove 14. The two cooperate with each other to ensure the scraping effect of the annular filter scraper 11. The annular filter scraper 11 tilts when moving in the filter cartridge 1.

[0031] The magnetic suction cylinder 4 includes an annular cover 41 , and arc-shaped magnets 42 are bonded to the outside of the annular cover 41 at intervals. The arc-shaped magnets 42 can effectively absorb the metal particles on the inner wall.

[0032] The inner side of the feed cover 2 is provided with a thread, and the outer side of the top of the filter cartridge 1 is provided with a thread. The feed cover 2 is threadedly connected to the filter cartridge 1, which is convenient for disassembly of the feed cover 2 and subsequent shaking off of the magnetic metal. After the feed cover 2 is disassembled, the magnetic suction cylinder 4 can slide out from this side.

[0033] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
