The positioning mechanism 3 includes a supporting component 31 and a rotating component 32. The supporting component 31 is located on the surface of the box body 1 and is connected to the filter screen 2. The supporting component 31 is used to control the annular filter screen 2 to maintain a vertical state and extend to the outside of the box body 1. The rotating component 32 is connected to the supporting component 31. The rotating component 32 controls the filter screen 2 to rotate in the inner cavity of the box body 1 by cooperating with the supporting component 31. The top of the box body 1 is provided with a positioning mechanism 3 that cooperates with the filter screen 2.

The filter screen 2 can efficiently filter impurities in the water, and the impurities will adhere to the surface of the filter screen 2. The rotating component 32 cooperates with the supporting component 31 to control the filter screen 2 to rotate in the inner cavity of the box body 1. When the filter screen 2 rotates, it can move synchronously with the attached impurities. When the filter screen 2 drives the impurities to move to the outside of the box body 1, the driving part 413 cooperates with the blowing part 412 to blow air from the inside of the filter screen 2 to the outside of the filter screen 2. When blowing, the impurities can be automatically blown to the outer wall of the filter screen 2 as a whole. The cleaning part 422 can automatically clean the impurities attached to the outer wall of the filter screen 2, and can further put the cleaned impurities into the collection box 421. The cleaned filter screen 2 continues to rotate to the inner cavity of the box body 1, and the filter screen 2 can continue to efficiently filter and purify the impurities in the water.

[0024] like Figure 1 , Figure 2 , Figure 3 As shown, as a preferred embodiment of the present invention, the support assembly 31 includes a plurality of sets of parallel distributed rotating rods 311 that are rotatably installed with two sets of vertical plates 7, a plurality of sets of parallel distributed bottom support rollers 312 are rotatably installed at the bottom of the box body 1, a top support roller 313 is fixedly installed on the surface of the rotating rod 311, and the filter screen 2 is sleeved between the bottom support roller 312 and the top support roller 313.

[0027] When in use, the first motor 324 drives a group of rotating rods 311 to rotate and then drives the synchronous gear plate 321 to rotate synchronously. Multiple groups of synchronous gear plates 321 cooperate with the synchronous belt 322 to drive multiple groups of rotating rods 311 to rotate, and the rotating rods 311 drive the top support roller 313 to rotate.

[0028] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the blowing part 412 includes blowing ports 4121 respectively opened at the top ends of the two opposite side walls of the blow tube 411, an air inlet hole 4122 is opened in the middle of the side wall of the blow tube 411, and a piston plate 4123 is slidably installed in the vertical direction inside the blow tube 411.

[0029] When in use, the driving unit 413 controls the piston plate 4123 to move back and forth in the vertical direction in the hair dryer 411. When the piston plate 4123 moves downward to below the air inlet hole 4122, the outside air flows into the hair dryer 411 through the air inlet hole 4122. When the piston plate 4123 moves upward, especially when the piston plate 4123 moves upward above the air inlet hole 4122, the piston plate 4123 squeezes the air in the hair dryer 411, and then the air in the hair dryer 411 can be blown to the outside of the hair dryer 411 through the blowing port 4121. The blowing port 4121 blows the high-pressure air toward the filter 2, which can conveniently blow impurities attached to the filter 2 to the outer wall of the filter 2, making it easier to clean it later.

The annular side wall of the fixed plate 4135 is provided with a ring gear 4137. A transmission column 4138 is rotatably installed between the two groups of vertical plates 7. The transmission column 4138 is located below the fixed plate 4135 and passes through the hair dryer 411. A transmission gear plate 4139 meshing with the ring gear 4137 is fixedly installed on the surface of the transmission column 4138. One end of the transmission column 4138 extends to the outside of the vertical plate 7 and is connected to the second motor 4130.

[0031] When in use, the second motor 4130 drives the transmission column 4138 to rotate, and the transmission column 4138 drives the transmission gear plate 4139 to rotate. The transmission gear plate 4139 engages with the gear ring 4137 for transmission, which can drive the fixed plate 4135 to rotate and then drive the clamping column 4136 to rotate synchronously. The clamping column 4136 and the clamping slot 4133 cooperate with each other to push the cross plate 4134 to reciprocate in the vertical direction. The cross plate 4134 and the connecting rod 4131 cooperate with each other to push the piston plate 4123 to reciprocate in the vertical direction in the inner cavity of the hair dryer 411.

[0033] The transmission column 4138 drives the main guide toothed disc 4224 to rotate, and the main guide toothed disc 4224 and the slave guide toothed disc 4223 are meshed and driven to drive the cleaning rod 4221 to rotate, and the cleaning rod 4221 drives the brush 4222 to rotate synchronously, and the rotating brush 4222 can efficiently clean the impurities attached to the outer wall of the filter screen 2. The cleaned impurities fall into the collection box 421.

Through the cooperation between the positioning groove 5 and the positioning block 6, the collection box 421 can be easily installed and removed on the surface of the box body 1.

[0035] The working principle of the present invention is: when in use, the water to be filtered and purified is transported to the inner cavity of the box body 1 through the water inlet pipe 11. When the water flows in the inner cavity of the box body 1, it will pass through the surface of the filter screen 2. The filter screen 2 can efficiently filter impurities in the water. The impurities will adhere to the surface of the filter screen 2. The first motor 324 drives a group of rotating rods 311 to rotate and then drives the synchronous gear plate 321 to rotate synchronously. Multiple groups of synchronous gear plates 321 and synchronous belts 322 cooperate with each other to drive multiple groups of rotating rods 311 to rotate. The rotating rods 311 drive the top support rollers 313 to rotate. The top support rollers 313 and the bottom support rollers 312 cooperate with each other to drive the filter screen 2 to rotate in the inner cavity of the box body 1.

[0036] When the filter screen 2 rotates, it can move synchronously with the attached impurities. When the filter screen 2 drives the impurities to move to the outside of the box body 1, the second motor 4130 drives the transmission column 4138 to rotate, and the transmission column 4138 drives the transmission gear plate 4139 to rotate. The transmission gear plate 4139 engages with the gear ring 4137 for transmission, which can drive the fixed plate 4135 to rotate and then drive the clamping column 4136 to rotate synchronously. The clamping column 4136 and the clamping groove 4133 cooperate with each other to push the cross plate 4134 to reciprocate in the vertical direction. The cross plate 4134 and the connecting rod 4131 cooperate with each other to push the piston plate 4123 to reciprocate in the vertical direction in the inner cavity of the hair dryer 411. When the piston plate 4123 moves downward to below the air inlet hole 4122, the outside air flows into the hair dryer 411 through the air inlet hole 4122. When the piston plate 4123 moves upward, especially when the piston plate 4123 moves upward above the air inlet hole 4122, the piston plate 4123 squeezes the air in the hair dryer 411, and then the air in the hair dryer 411 can be blown to the outside of the hair dryer 411 through the blowing port 4121. The blowing port 4121 blows the high-pressure air toward the filter 2, which can conveniently blow impurities attached to the filter 2 to the outer wall of the filter 2, making it easier to clean it later. The transmission column 4138 drives the main guide toothed disc 4224 to rotate, and the main guide toothed disc 4224 and the slave guide toothed disc 4223 are meshed and driven to drive the cleaning rod 4221 to rotate, and the cleaning rod 4221 drives the brush 4222 to rotate synchronously, and the rotating brush 4222 can efficiently clean the impurities attached to the outer wall of the filter screen 2.
