[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1 - Figure 8This utility model provides an embodiment of a fully automatic backwashing water filter, including a water purifier housing 1, a top cover 4 disposed on the water purifier housing 1, a mounting assembly disposed on the water purifier housing 1, a bracket 5 fixedly connected to the water purifier housing 1, a connection port 21 fixedly connected to the water purifier housing 1, a first valve body 222 threadedly connected to the connection port 21, a first through hole 217 and a second through hole 218 formed on the first valve body 222, a second valve body 220 disposed inside the first valve body 222, an energy-absorbing pin 221 fixedly connected to the second valve body 220, and a pin fixedly connected to the first valve body 220. The following components are included: a limiting pin 219 inside the 222; an elbow 22 threaded into the connection port 21; a first tee connector 24 on one side of the elbow 22; a drain port 26 fixedly connected to the end of the first tee connector 24 away from the elbow 22; a first solenoid valve 25 fixedly connected to the drain port 26; a third tee connector 212 on one side of the first tee connector 24; a third solenoid valve 213 fixedly connected to the third tee connector 212; a water inlet 214 fixedly connected to the end of the third tee connector 212 away from the water purifier housing 1; a second tee connector 27 fixedly connected to the top cover 4; and a fixed... A purified water outlet 210 is connected to the end of the second three-way connector 27 furthest from the inlet 214. A second solenoid valve 28 is fixedly connected to the purified water outlet 210. The top cover 4 is installed on the water purifier housing 1 via an installation assembly. When the water purifier housing 1 is operating normally, the second valve body 220 moves upward with the water flow, closing the six second through holes 218 on the first valve body 222, creating a relatively flat space at the bottom of the water purifier housing 1. The dirt filtered out by the water purifier housing 1 will deposit at the bottom of the water purifier housing 1. Water flows into the inner cavity of the water purifier housing 1 through the first through hole 217. When backflushing is required, The first solenoid valve 25, the second solenoid valve 28, and the third solenoid valve 213 are simultaneously energized. The second valve body 220 moves downward with the water flow, and the six second through holes 218 on the first valve body 222 are opened. The previously deposited dirt is quickly discharged from the first through hole 217 and the second through hole 218 to the drain port 26 under the influence of the water flow, making the process simple and easily achieving water purification and sewage discharge. The installation component allows for the installation and removal of the top cover 4 and the water purifier housing 1, making it convenient to process the inner cavity of the water purifier housing 1, thereby improving the practicality and operational stability of the water purifier housing 1.

[0027] Please see Figure 2 - Figure 5In this embodiment, six first through holes 217 are provided, symmetrically distributed on the first valve body 222, and six second through holes 218 are provided, symmetrically distributed on the first valve body 222. The position of the second valve body 220 controls the sealing of the second through holes 218, thereby facilitating normal use and backflushing of the water purifier casing 1 and improving automation. The first valve body 222 has corresponding through holes at corresponding positions on the second valve body 220. The second valve body 220 is disposed inside the through holes of the first valve body 222, facilitating the sealing of the second valve body 222. The body 220 moves up and down inside the first valve body 222, making it easy to control according to the water flow and improving the practicality of the device. A second connecting pipe 211 is fixedly connected between the third three-way connector 212 and the second three-way connector 27. A rigid pipe 29 is fixedly connected to the bottom of the first through hole 217. The rigid pipe 29 is located inside the top cover 4 of the water purifier shell 1. A positioning net 223 is fixedly connected inside the water purifier shell 1. A filter cotton 224 is set on the positioning net 223. A filter barrel 216 is set inside the filter cotton 224. The first valve body 222 is set on the positioning net 222. At the lower part of 23, a third connecting pipe 215 is fixedly connected between the third tee connector 212 and the first tee connector 24. A first connecting pipe 23 is fixedly connected between the first tee connector 24 and the elbow 22. When the water purifier housing 1 is operating normally, the second valve body 220 moves upward with the water flow, sealing the six second through holes 218 on the first valve body 222, creating a relatively flat space at the bottom of the water purifier housing 1. The dirt filtered out by the water purifier housing 1 will accumulate at the bottom of the water purifier housing 1. Water flows into the inner cavity of the water purifier housing 1 through the first through hole 217. During backwashing, the first solenoid valve 25, the second solenoid valve 28, and the third solenoid valve 213 are simultaneously energized. The second valve body 220 moves downward with the water flow, and the six second through holes 218 on the first valve body 222 are opened. The previously deposited dirt is quickly discharged from the first through hole 217 and the second through hole 218 to the drain port 26 under the influence of the water flow. The filter cotton 224 has a matching groove at the corresponding position of the filter barrel 216. The filter barrel 216 is placed in the groove of the filter cotton 224, so that it positions and installs the filter barrel 216, improving the practicality of the filter barrel 216.

[0028] Please see Figure 6 - Figure 8In this embodiment, the installation assembly includes a limiting frame 31 fixedly connected to the bottom of the top cover 4, a fixing bracket 32 ​​fixedly connected to the water purifier housing 1, a first pin 33 disposed inside the fixing bracket 32, a rotating block 34 disposed on the first pin 33, a threaded rod 35 fixedly connected to the rotating block 34, a washer 36 disposed on the threaded rod 35, a threaded block 37 threadedly connected to the threaded rod 35, a second pin 38 disposed on the first pin 33, a semi-circular block 39 slidably connected inside the second pin 38, a spring 310 fixedly connected between the semi-circular block 39 and the second pin 38, and a pull ring 311 movably connected inside the second pin 38. The threaded rod 35 is disposed inside the top cover 4. The installation assembly facilitates the installation and removal of the top cover 4 and the water purifier housing 1, making it easier to process the inner cavity of the water purifier housing 1 and improving the practicality of the water purifier housing 1. To improve the operational stability of the water purifier housing 1, the top cover 4 has a corresponding through groove at the position of the threaded rod 35. The threaded rod 35 is located inside the through groove of the top cover 4, making it easy to screw the threaded block 37 onto the threaded rod 35, thus installing the top cover 4 and the water purifier housing 1 and improving the stability of the installation. The second pin 38 has a corresponding round hole at the position of the semi-circular block 39. The semi-circular block 39 is slidably connected inside the round hole of the second pin 38, so that when the second pin 38 is inserted into the through hole of the first pin 33, the first pin 33 contacts the semi-circular block 39. The semi-circular block 39 is slidably moved into the groove of the second pin 38 by the arc surface, compressing the spring 310, so that the second pin 38 can pass through the first pin 33. When the semi-circular block 39 is not pressed, the compression spring 310 drives the semi-circular block 39 to return to its original position, thus limiting the first pin 33.

[0029] During operation, the first valve body 222 is screwed into the connection port 21 of the water purifier housing 1 to install it. The filter cartridge 216 is then placed inside the water purifier housing 1, positioned by the first valve body 222. The top cover 4 is then placed over the water purifier housing 1, positioned by the limiting frame 31. The rotating block 34 is fitted onto the first pin 33, which is then inserted into the through hole of the fixing bracket 32. The second pin 38 is then inserted into the through hole of the first pin 33 to limit its position. The angle of the top cover 4 is adjusted, and the threaded rod 35 is moved into the corresponding through groove of the top cover 4. Finally, the gasket 36 is fitted onto the threaded rod 35, and the threaded block 37 is screwed in to align the top cover 4 with the filter cartridge 32. The water purifier housing 1 is installed and fixed to improve its practicality. During normal operation, with the first solenoid valve 25, the second solenoid valve 28, and the third solenoid valve 213 all de-energized, water flows in from the inlet 214, through the third connecting pipe 215 and the first connecting pipe 23 into the inner cavity of the water purifier housing 1, and then out through the rigid pipe 29 from the purified water outlet 210. The energy-absorbing pin 221 on the second valve body 220 is impacted by the upward water flow, causing the second valve body 220 to move upward with the water flow, sealing the six second through holes 218 on the first valve body 222. This creates a relatively flat space at the bottom of the water purifier housing 1, where the filtered impurities accumulate. Water flows through the first through hole 217 into the inner cavity of the water purifier housing 1, rinsing the filter cartridge 216. Figure 4 As shown, the dirt storage space has been increased. When backwashing is required, the first solenoid valve 25, the second solenoid valve 28, and the third solenoid valve 213 are simultaneously energized. At this time, water flows in from the inlet 214, passes through the second connecting pipe 211 and the rigid pipe 29, and enters the inner cavity of the water purifier housing 1. Finally, it is discharged from the drain outlet 26 through the first connecting pipe 23. The energy-absorbing pin 221 on the second valve body 220 is impacted by the downward water flow inside the water purifier housing 1. As the water flows downward, the six second through holes 218 on the first valve body 222 are opened. The previously deposited dirt is quickly discharged from the first through hole 217 and the second through hole 218 to the drain port 26 under the influence of the water flow, as shown in Figure 5. The limiting pin 219 inside the first valve body 222 and the elbow 22 threadedly connected to the connection port 21 limit the second valve body 220, so that the second valve body 220 can move up and down, but will not detach from the first valve body 222.

[0030] By using time relays to control the power supply of the first solenoid valve 25, the second solenoid valve 28, and the third solenoid valve 213, the fully automatic water purification and reverse discharge process is achieved. The entire process can be automated, running on an hourly, daily, or weekly basis, depending on individual needs. No manual intervention is required throughout the process.

[0031] Through the above steps, when the water purifier housing 1 is operating normally, the second valve body 220 moves upward with the water flow, sealing the six second through holes 218 on the first valve body 222, so that a relatively flat space is formed at the bottom of the water purifier housing 1. The dirt filtered out by the water purifier housing 1 will be deposited at the bottom of the water purifier housing 1. The water flows into the inner cavity of the water purifier housing 1 through the first through hole 217. When backwashing is required, the first solenoid valve 25, the second solenoid valve 28 and the third solenoid valve 213 are energized at the same time. The second valve body 220 moves downward with the water flow, and the six second through holes 218 on the first valve body 222 are opened. The previously deposited dirt is quickly discharged from the first through hole 217 and the second through hole 218 to the drain port 26 under the influence of the water flow. This solves the problem that most water purifiers on the market basically require manual intervention to achieve backwashing, and some water purifiers, although they can backwash, do not clean thoroughly and some dirt remains.
