[0025] When in use, first install the valve filter on the pipeline, connect the water inlet pipe 102 and the water outlet pipe 101 to the pipeline respectively, then the water flows into the filter housing 1 through the water inlet pipe 102, and the water flow is adsorbed and filtered under the action of the activated carbon filter layer 104 inside the filter housing 1, and the filtered water flow is discharged through the water outlet pipe 101.

[0026] Furthermore, if Figure 2 As shown, a cleaning mechanism 2 is provided at the bottom of the filter housing 1, and the cleaning mechanism 2 consists of a cleaning component 201 and a sewage outlet 202. A sewage outlet 202 is opened at the bottom of the filter housing 1, and the sewage outlet 202 is located below the activated carbon filter layer 104. A cleaning component 201 is provided below the sewage outlet 202, and a collecting bucket 2011, a control valve 2012 and a sewage pipe 2013 are provided inside the cleaning component 201.

A sewage pipe 2013 is fixed at the bottom of the collecting bucket 2011, and a control valve 2012 is mounted on the surface of the sewage pipe 2013.

[0027] When in use, since the activated carbon filter layer 104 is an inclined structure, impurities attached to the surface of the activated carbon filter layer 104 can fall into the sewage outlet 202 under the action of gravity and fall into the collection bucket 2011. If impurities need to be cleaned, it is only necessary to open the control valve 2012 when the pipeline stops conducting water, so that the impurities inside the collection bucket 2011 can be discharged through the sewage pipe 2013, thereby making it easier for the valve filter to clean impurities.

[0028] Furthermore, if Figure 3 As shown, the filter housing 1 and the cover body 103 are detachably connected through the maintenance mechanism 3, and the interior of the maintenance mechanism 3 includes a slide bar 301, a maintenance component 302 and a slide groove 303. The surfaces of both sides of the activated carbon filter layer 104 are fixed with slide bars 301, and the inner walls on both sides of the filter housing 1 are provided with slide grooves 303. The slide grooves 303 and the slide bar 301 slide with each other. The filter housing 1 and the cover body 103 are detachably connected through the maintenance component 302. The maintenance component 302 consists of a fastening bolt 3021, a threaded hole 3022 and a sealing gasket 3023. The inner wall of the cover body 103 is adhered with a sealing gasket 3023, and the surface of the sealing gasket 3023 is tightly fitted with the surface of the filter housing 1. Threaded holes 3022 are provided on both sides at the top position of the filter housing 1, and fastening bolts 3021 are threadedly connected to both sides of the cover body 103. One side of the fastening bolt 3021 passes through the cover body 103 and is threadedly fastened with the threaded hole 3022.

[0029] When in use, the filter housing 1 and the cover body 103 can be sealed under the action of the sealing gasket 3023, and the filter housing 1 and the cover body 103 can be fixed under the threaded cooperation of the fastening bolt 3021 and the threaded hole 3022. If it is necessary to inspect or replace the activated carbon filter layer 104, the fastening bolt 3021 can be loosened when the pipeline stops conducting water, so that the fastening bolt 3021 is away from the threaded hole 3022, and then the cover body 103 is removed, and the filter housing 1 is opened for inspection. At the same time, the activated carbon filter layer 104 can be pulled out and taken out for replacement under the sliding cooperation of the slide bar 301 and the slide groove 303, so as to realize the function of easy maintenance of the valve filter.

[0030] Furthermore, if Figure 4As shown, a slow flow mechanism 4 is provided at one end of the water outlet pipe 101, and the slow flow mechanism 4 is composed of a slow flow component 401 and a fixed plate 402. One end of the water outlet pipe 101 is covered with a fixed plate 402, and the fixed plate 402 is detachably connected to the inner wall of the filter housing 1 by screws. The surface of the fixed plate 402 is provided with a slow flow component 401, and the interior of the slow flow component 401 includes a baffle 4011, a slow flow port 4012 and a baffle 4013. A baffle 4013 is fixed to one side of the fixed plate 402, and the structure of the baffle 4013 is an inclined structure. One end of the baffle 4013 is in contact with the surface of the activated carbon filter layer 104, and a slow flow port 4012 is opened at the bottom position of the fixed plate 402. One side of the slow flow port 4012 is covered with a baffle 4011, and one end of the baffle 4011 is rotatably connected to the surface of the fixed plate 402.

[0031] When in use, the slow flow outlet 4012 can be blocked by the action of the baffle 4011, and the water flow will impact the baffle 4011 after being filtered through the activated carbon filter layer 104, causing the baffle 4011 to rotate and open, allowing the water flow to be discharged through the slow flow outlet 4012. The slow flow outlet 4012 can slow down the time for water to flow into the outlet pipe 101, so that the water flow can fully contact the activated carbon filter layer 104. At the same time, under the action of the baffle 4013, the water flow on the top of the baffle 4013 can be intercepted, so that the water flow needs to pass through the bottom position of the activated carbon filter layer 104 and then be discharged through the slow flow outlet 4012, so that the water flow can fully contact the activated carbon filter layer 104, so as to realize the slow flow function of the valve filter on the water flow.

[0032] Working principle: When in use, first install the valve filter on the pipeline, connect the water inlet pipe 102 and the water outlet pipe 101 to the pipeline respectively, then the water flows into the filter housing 1 through the water inlet pipe 102, and the water flow is adsorbed and filtered under the action of the activated carbon filter layer 104 inside the filter housing 1, and the filtered water flow is discharged through the water outlet pipe 101.

[0033] Since the activated carbon filter layer 104 is an inclined structure, impurities attached to the surface of the activated carbon filter layer 104 can fall into the sewage outlet 202 under the action of gravity and fall into the collection bucket 2011. If impurities need to be cleaned, it is only necessary to open the control valve 2012 when the pipeline stops conducting water, so that the impurities in the collection bucket 2011 can be discharged through the sewage pipe 2013, thereby making it easier for the valve filter to clean impurities.

[0034] At this time, the slow flow outlet 4012 can be blocked by the action of the baffle 4011, and the water flow will impact the baffle 4011 after being filtered through the activated carbon filter layer 104, causing the baffle 4011 to rotate and open, allowing the water flow to be discharged through the slow flow outlet 4012. The slow flow outlet 4012 can slow down the time for water to flow into the outlet pipe 101, so that the water flow can fully contact with the activated carbon filter layer 104. At the same time, the water flow on the top of the baffle 4013 can be intercepted by the action of the baffle 4013, so that the water flow needs to pass through the bottom position of the activated carbon filter layer 104 and then be discharged through the slow flow outlet 4012, so that the water flow can fully contact with the activated carbon filter layer 104, so as to realize the slow flow function of the valve filter on the water flow, increase the contact time between the water flow and the activated carbon filter layer 104, and thus improve the filtering effect of the valve filter when in use.

[0035] At this time, the filter housing 1 and the cover body 103 can be sealed under the action of the sealing gasket 3023, and the filter housing 1 and the cover body 103 can be fixed under the threaded cooperation of the fastening bolt 3021 and the threaded hole 3022. If it is necessary to inspect or replace the activated carbon filter layer 104, the fastening bolt 3021 can be loosened when the pipeline stops conducting water, so that the fastening bolt 3021 is away from the threaded hole 3022, and then the cover body 103 is removed, and the filter housing 1 is opened for inspection. At the same time, the activated carbon filter layer 104 can be pulled out and the activated carbon filter layer 104 can be taken out for replacement under the sliding cooperation of the slide bar 301 and the slide groove 303, so as to realize the function of facilitating the inspection of the valve filter, thereby improving the convenience of the valve filter during inspection and finally completing the use of the valve filter.
