Detailed Description

The technical solution of the present invention is further explained with reference to the accompanying drawings and specific embodiments.

Example one

As shown in fig. 1-3, the household purifier filter element with a cleaning mechanism provided by the utility model comprises an outer shell 1 and a sealing cover 2 in threaded connection with the outer shell 1, two clamping ring plates 3 are arranged inside the outer shell 1, a filter cartridge 5 and a filter membrane layer 6 are clamped between the two clamping ring plates 3, the filter membrane layer 6 is sleeved on the periphery of the filter cartridge 5, a bypass valve 12 is arranged on the right side of the clamping ring plate 3 on the right side, a three-way pipe 8 and a water outlet pipe 10 are connected to the sealing cover 2 in an intercommunicating manner, one end of the three-way pipe 8 is connected to the water outlet pipe 10 in an intercommunicating manner, the other end of the three-way pipe 8 is communicated with an external water inlet pipe 7, a valve a91 and a valve b92 are respectively arranged at two ends of the three-way pipe 8 far away from the water inlet pipe 7, and a valve c93 is arranged on the water outlet pipe 10.

In this embodiment: the outer wall intercommunication of shell body 1 is connected with blow off pipe 11, installs valve d94 on the blow off pipe 11, and under the state of automatic clearance, valve d94 is opened, and the interior sewage of shell body 1 can be followed blow off pipe 11 and discharged, and in practical application, blow off pipe 11 is connected with external waste water discharge pipe.

In a normal use state, the valve a91 and the valve c93 are opened, the valve d94 and the valve b92 are closed, so that the filter element can normally work, water passes through the three-way pipe 8 from the water inlet pipe 7 and the three-way pipe 8 to the outer shell 1, is filtered by the filter membrane layer 6 under the extrusion of water pressure, flows out of the middle part of the filter cartridge 5 and is finally discharged from the water outlet pipe 10 to achieve the filtering and purifying effect, when the filter membrane layer 6 is excessively blocked due to the accumulation of filtered impurities, the water pressure is increased, a small amount of water passes through the filter membrane layer 6, and a large amount of water is conveyed into the filter cartridge 5 through the bypass valve 12, so that the condition that the water cannot be discharged due to the blockage of the filter element is avoided, and the filter element is easily damaged; at this moment, the filter element needs to be cleaned, at this moment, the valve a91 and the valve c93 are closed, the valve d94 and the valve b92 are opened, water flows into the three-way pipe 8 from the water inlet pipe 7 and flows into the outer shell 1 from the water outlet pipe 10, then flows out from the inside of the filter cartridge 5, takes away impurities attached to the filter membrane layer 6, and finally is discharged from the sewage discharge pipe 11, so that the purpose of automatic cleaning is achieved, the trouble of replacing the filter element is omitted, and the use cost of a product is reduced.
