Description

Technical Field

[0001] The present invention relates to the technical field of fluid control, and more specifically to a filter and a valve with a filter. Background Art

[0002] Generally, a filter is installed on the household water inlet pipeline of urban water supply. The filter can intercept large particle impurities such as rust, sediment, welding slag, and insect eggs in the water, and prevent these impurities from accumulating at the pipe elbows, pipe diameter changes, or some narrow parts after entering the pipeline, causing pipeline blockage and affecting the normal flow of water. However, the filter of the prior art has a simple structure and still has the following defects during use: 1. The filter can only filter large particle impurities in the water, and it is difficult to filter fine iron particles. If the mesh number of the filter screen is increased, the filter screen is easily blocked, affecting the water flow. 2. Larger particle impurities are filtered, but after being washed by the water flow and colliding with each other in the filter screen and the sedimentation tank, their particle size gradually becomes smaller and still enters the household through the filter screen. 3. The filtered impurities are collected inside the filter, and it is difficult for users to identify the accumulation of iron impurities inside, so they cannot be disassembled and cleaned in time. More residual iron impurities are harmful to human health and also damage the household water appliances. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a filter. A magnet is provided inside the filter, and the magnet can timely adsorb the iron components in the filtered impurities, effectively intercepting the leakage of fine iron impurity particles from the filter screen; it can remind users or managers to timely disassemble the sewage outlet of the filter and clean the internal impurities in time.

[0004] The technical solution of the present invention is to provide a filter, including a pipeline. The pipeline includes a first channel, a second channel, and a filtering channel. The filtering channel is arranged between the first channel and the second channel; the inlet of the filtering channel is connected to the outlet of the first channel, and the outlet of the filtering channel is connected to the inlet of the second channel; a filter screen is provided inside the filtering channel. The filtering channel is inclined, and a slideway is provided on the side wall at the lowest part of the filtering channel. A magnet is slidably fitted in the slideway, and a transparent area for observing the magnet in the slideway is provided on the side wall of the chute; when a certain amount of iron filings accumulates in the filtering cavity, it can attract the magnet to slide in the slideway.

[0005] After adopting the above structure, the filter of the present invention has the following advantages compared with the prior art: Since the filtering channels of the filter of the present invention are inclined, magnets are provided in the slideways at the lowest positions of the filtering channels, and iron filings entering the filtering channels will be attracted by the magnets and adsorbed at the lowest positions inside the filtering channels. In this way, both large and small iron filings will be adsorbed at the lowest positions inside the filtering channels, preventing small iron filings from flowing out of the filter screen.

[0006] The iron filings are adsorbed at the lowest positions inside the filtering channels and no longer move, and they will not collide with each other even under the scouring of water flow, preventing the particle size from gradually becoming smaller due to particle collisions and then passing through the filter screen into the indoor area.

[0007] In the initial state, due to the action of gravity, the magnets are at the lowest positions of the channels. When a certain amount of iron filings accumulates, the magnets will be attracted upward and slide inside the slideways. The positions of the magnets inside the slideways can be observed through the transparent areas, thereby determining the quantity of iron filings inside the filtering channels. When the user observes that the magnets are not at the lowest positions of the channels, the filter can be cleaned in a timely manner to prevent a large amount of residual iron impurities from harming human health and damaging indoor water-using appliances at the same time.

[0008] As an improvement, the inlet of the filtering channel is provided at the highest end of the filtering channel, and the outlet of the filtering channel is provided on the side wall of the filtering channel. After adopting this structure, the connection structure between the filtering channel and the first channel and the second channel can be set more reasonably, which is convenient for implementation.

[0009] As an improvement, the filter screen is of a cylindrical structure, and the inlet of the filtering channel is in communication with the inner cavity of the filter screen; the outlet of the filtering channel is located outside the filter screen, and the fluid flows in from the inlet of the filter screen channel, is filtered by the filter screen, and then flows out from the outlet of the filter screen channel. After adopting this structure, the filtering effect is better and the fluidity of the fluid is better.

[0010] As an improvement, inclined convex necks are provided on the side walls of the filtering channels. The convex necks are of a hollow structure, and the inner cavities of the convex necks are in communication with the inner cavities of the filtering channels; openings are provided at the lowest ends of the convex necks, and end caps are detachably connected to the openings; the slideways are provided inside the end caps. After adopting this structure, the inside of the filtering channels can be cleaned by removing the end caps, and both disassembly and cleaning are very convenient.

[0011] As an improvement, a chute is provided on one side of the end cap away from the convex neck, and a transparent cover is provided at the opening of the chute. The inner cavity of the chute and the inner cavity of the transparent cover form the slideway. After adopting this structure, the transparent cover is provided at the opening. That is, when the magnets are still inside the transparent cover, the internal iron filings have not reached the level that needs to be cleaned. When the magnets cannot be seen inside the transparent cover, the filtering channels need to be cleaned. The structure is simple and the indication effect is good.

[0012] As an improvement, a limiting groove is provided on the side wall at the opening of the sliding groove, and the end of the transparent cover is inserted into the limiting groove; a limiting step is provided on the outer side wall of the transparent cover, a compression nut is sleeved outside the transparent cover and the compression nut is connected to the end cover, and the limiting step abuts against the inner edge of the compression nut. After adopting this structure, the transparent cover is sleeved on the end cover through the compression nut, with a simple structure and convenient assembly.

[0013] As an improvement, an annular socket is provided at the inlet of the filtering channel, and one end of the filter net is sleeved outside the annular socket; an embedding groove is provided on the inner side of the end cover, and the other end of the filter net is inserted into the embedding groove; an impurity accommodating groove is further provided on the inner side of the end cover, and the impurity accommodating groove is located inside the embedding groove. After adopting this structure, both ends of the filter net are respectively sleeved on the annular socket and embedded in the embedding groove, which can effectively prevent impurities from slipping out of the connection parts at both ends of the filter net and entering the indoor pipeline.

[0014] As an improvement, a check valve assembly is provided in the filtering channel, and the check valve assembly includes a valve core and a return elastic member; a valve core seat is provided in the filtering channel, and one end of the valve core is slidably matched with the valve core seat; the return elastic member is installed between the valve core seat and the valve core, and the sealing end of the valve core abuts against the inlet of the filtering channel under the action of the return elastic member to seal the inlet of the filtering channel. After adopting this structure, the check valve and the filter are combined into one, saving costs and reducing leakage points; compared with the simple series structure between the check valve and the valve body in the prior art, this solution is an internal check structure, with convenient assembly, small flow loss, and low integrated manufacturing cost.

[0015] As an improvement, a guiding groove is provided on the valve core seat, one end of the valve core is slidably matched in the guiding groove, a first spring seat is provided at the opening of the guiding groove, a second spring seat is provided on the side wall of the valve core, the return elastic member is a return spring, one end of the return spring is sleeved on the first spring seat, and the other end of the return spring is sleeved on the second spring seat. After adopting this structure, the valve core installation structure is simple, the assembly is convenient, and the guiding groove plays a guiding role for the valve core.

[0016] Another technical problem to be solved by the present invention is to provide a valve with a filter. A magnet is provided in the filter of the valve, and the magnet can timely adsorb the iron components in the filtered impurities, effectively intercepting the leakage of finer iron impurity particles through the filter net; it can remind users or managers to timely disassemble the drain port of the filter and clean the internal impurities in time.

[0017] The technical solution of the present invention is to provide a valve with a filter, which includes a valve body and also includes a filter with the above structure. The second channel of the filter is connected to the inlet channel of the valve body.

[0018] After adopting the above structure, the valve with a filter of the present invention has the following advantages compared with the prior art: Since the valve of the present invention is equipped with a filter, the filter can filter out impurities and suck the iron filings at the lowest part of the filter channel, avoiding small iron filings from flowing out of the filter screen and also preventing the particles from colliding with each other and gradually becoming smaller and then entering the indoor through the filter screen. A magnet is arranged in the filter, which can remind the user to clean the impurities in the filter in time, avoid more residual iron impurities from harming human health and damaging the indoor water-using appliances at the same time.

The filtering channel 3 is inclined. The inlet 317 of the filtering channel is connected to the outlet of the first channel 1, and the outlet 318 of the filtering channel is connected to the inlet of the second channel 2. After the fluid enters from the first channel 1 and is filtered by the filtering channel 3, it then flows out from the second channel 2.

[0028] An inclined convex neck 301 is provided on the side wall of the filtering channel 3. The convex neck 301 is a hollow structure and is coaxial with the filtering channel 3. The inner cavity of the convex neck 301 communicates with the inner cavity of the filtering channel 3.

[0029] A filter net 303 is provided in the filtering channel 3. The filter net 303 is a cylindrical structure. A ring-shaped socket 304 is provided at the inlet 317 of the filtering channel, and one end of the filter net 303 is sleeved outside the ring-shaped socket 304. An embedding groove 305 is provided on the inner side of the end cover 302, and the other end of the filter net 303 is inserted into the embedding groove 305. An impurity accommodating groove 306 is also provided on the inner side of the end cover 302, and the impurity accommodating groove 306 is located inside the embedding groove 305. The inlet 317 of the filtering channel communicates with the inner cavity of the filter net 303; the outlet 318 of the filtering channel is located outside the filter net 303. The fluid flows into the filter net 303 from the inlet of the filter net 303 channel, is filtered by the filter net 303, and then flows out from the outlet of the filter net 303 channel.

[0030] On one side of the end cap 302 away from the convex neck 301, there is a sliding groove 307, that is, the sliding groove 307 is provided at the lowest part of the end cap 302. At the opening of the sliding groove 307, there is a transparent cover 308. The inner cavity of the sliding groove 307 and the inner cavity of the transparent cover 308 form a slideway, and the slideway is coaxial with the convex neck 301. A magnet 309 is slidably fitted in the slideway, and the magnet 309 is a strong magnet. The length of the slideway is greater than the length of the magnet 309. In the initial state, the lower end of the magnet 309 is accommodated in the transparent cover 308, and the lower end of the magnet 309 can be seen through the transparent cover 308. On the side wall at the opening of the sliding groove 307, there is a limiting groove 310, and the end of the transparent cover 308 is inserted into the limiting groove 310; on the outer side wall of the transparent cover 308, there is a limiting step 311. A compression nut 312 is sleeved outside the transparent cover 308 and the compression nut 312 is connected to the end cap 302, and the limiting step 311 abuts against the inner edge of the compression nut 312.

[0031] A check valve assembly is provided in the filter channel 3. The check valve assembly includes a valve core 4 and a return elastic member.

The return elastic member is a return spring 5. One end of the return spring 5 is sleeved on the first spring seat 315, and the other end of the return spring 5 is sleeved on the second spring seat 316. Under the action of the return spring 5, the sealing end of the valve core 4 abuts against the inlet 317 of the filter channel to seal the inlet 317 of the filter channel.

[0032] When the filter of the present application works, the fluid flows in from the first channel 1 and pushes the valve core 4 away, so that the inlet 317 of the filter channel is conducted. Then the fluid enters the filter net 303. After being filtered by the filter net 303, it is discharged from the outlet 318 of the filter channel and enters the second channel 2. The impurities filtered by the filter net 303 remain in the impurity accommodation groove 306, and the iron filings 6 are attracted by the magnet 309 and adsorbed on the inner wall of the impurity accommodation groove 306. When a certain amount of iron filings 6 accumulates in the impurity accommodation groove 306, the magnet 309 can be attracted to slide in the slideway, and the lower end of the magnet 309 will leave the transparent cover 308. The user can see that there is no magnet 309 in the transparent cover 308. At this time, the impurities in the filter can be cleaned, which plays a role in timely reminding the user to clean.
