[0002] Negative ion water purification equipment is an advanced equipment that uses negative ion technology to purify water. Negative ions are negatively charged ions with strong redox and sterilization capabilities. Negative ion water purification equipment uses a negative ion generator to generate negative ions and dissolve them in water. Through chemical reactions with organic pollutants and microorganisms in the water, the purpose of purifying water is achieved.

[0003] In negative ion water purification equipment, a filter is usually set to filter impurities in the water.

DETAILED DESCRIPTION

[0040] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1:

[0042] refer to Figure 1-5A negative ion water purification device comprises a shell 1, an inlet pipe 101, and an outlet pipe 102. The inlet pipe 101 is arranged at the top of the shell 1. Filter chambers 103 are arranged on both sides of the shell 1. Each filter chamber 103 is provided with a filter screen 104. First diverter pipes 105 are arranged on both sides of the inlet pipe 101, and one end of the two first diverter pipes 105 is communicated with the inlet pipe 101, and the other end of each first diverter pipe 105 is communicated with the corresponding filter chamber 103. Each first diverter pipe 105 is provided with a sealing mechanism for sealing the inside thereof. An opening 106 is arranged at the top of the filter chamber 103, and a box door 107 is rotatably connected to the opening 106. A purification box 108 is arranged at the bottom of the shell 1, and a purification component for purifying water is arranged in the purification box 108.

[0043] By setting up two first diversion tubes 105 and a sealing mechanism for sealing the inside of the first diversion tubes 105, when the staff pours water into the water inlet pipe 101, the water will enter the corresponding filter chambers 103 through the first diversion tubes 105 on both sides. When the filter 104 needs to be cleaned, the first diversion tube 105 can be sealed by the sealing mechanism to prevent water from entering the filter chamber 103. At this time, the staff can open the box door 107 to clean the impurities on the surface of the filter 104, and the water can continue to work through the first diversion tube 105 on the other side, thereby improving the working efficiency of the negative ion water purification equipment.

[0044] refer to Figure 5 A water inlet 1081 is provided at the top of the purification box 108, and the purification components include an activated carbon plate 1082, a hollow ultrafiltration membrane 1083, a negative ion layer 1084, a negative ion generator 1085, and a reverse osmosis membrane layer 1086. The hollow ultrafiltration membrane 1083 is made of polyester material, and the reverse osmosis membrane layer 1086 is made of polytetrafluoroethylene. The activated carbon plate 1082 is arranged at the inner top of the purification box 108, the hollow ultrafiltration membrane 1083 is arranged at the bottom of the activated carbon plate 1082, the negative ion layer 1084 is arranged at the bottom of the hollow ultrafiltration membrane 1083, the negative ion generator 1085 is arranged inside the negative ion layer 1084, and the reverse osmosis membrane layer 1086 is arranged at the bottom of the negative ion layer 1084. The water outlet pipe 102 is arranged at the bottom of the purification box 108 and is connected to the inside of the purification box 108.

[0045] When the staff injects water into the water inlet pipe 101 through the water pump, the water will enter the corresponding filter chamber 103 through the first shunt pipes 105 on both sides, and the filter 104 will perform preliminary filtration on the particles in the water. Then, the water will enter the purification box 108 through the water inlet 1081 for final filtration. First, the water will pass through the activated carbon plate 1082 layer, and then pass through the hollow ultrafiltration membrane 1083 and the negative ion layer 1084 respectively. Under the action of the negative ion generator 1085, a large amount of negative ions will be generated, and the negative ions will react with water molecules to improve the water quality or purify the water. Finally, the water will enter the reverse osmosis membrane layer 1086 from the left channel of the negative ion layer 1084, and finally be discharged through the water outlet pipe 102. The reverse osmosis membrane layer 1086 is specifically responsible for removing bacteria and viruses in the water, thereby ensuring the purity of the water. In addition, when air is injected into the water inlet 1081, the negative ions can also purify the air.

[0046] Embodiment 2:

[0047] Based on the first embodiment, this embodiment refers to Figure 3-4 The sealing mechanism includes a sealing block 2, a sealing plate 201, and a cylinder 204 arranged on the side of the first shunt pipe 105. The sealing block 2 is arranged at the top of the shell 1. A sealing groove 202 is arranged inside the sealing block 2, and the sealing groove 202 is communicated with the inside of the first shunt pipe 105. The inner wall of the sealing groove 202 of the sealing plate 201 is slidably connected. The cylinder 204 is arranged at the top of the shell 1, and the output end of the cylinder 204 is fixedly connected to the sealing plate 201. Two fixing rings 913 are arranged inside the first shunt pipe 105. A fixing groove 203 is formed between the two fixing rings 913, and the position of the fixing groove 203 corresponds to the sealing plate 201. When the staff starts the cylinder 204, the output end of the cylinder 204 will drive the sealing plate 201 to move, and the sealing plate 201 will be slidably connected with the inner wall of the sealing groove 202 until the sealing plate 201 is extended to the inside of the fixing groove 203, and the bottom of the sealing plate 201 abuts against the bottom of the fixing groove 203.

[0048] When the sealing plate 201 seals the inside of the first shunt pipe 105, the fixed ring 913 is provided to form a support at the bottom of the sealing plate 201, thereby preventing uneven force on one side of the sealing plate 201 due to lack of support, thereby causing the sealing plate 201 to deform, and the service life of the sealing plate 201 can be improved. At the same time, the inner diameter of the fixed ring 913 on one side close to the top of the housing 1 is smaller than the inner diameter of the other fixed ring 913. A guide slope 914 is provided on the top of the fixed ring 913 on the side away from the top of the housing 1. In this way, when untreated water enters the inside of the first shunt pipe 105, the water will flow into the filter chamber 103 under the action of the guide slope 914. The difference in the inner diameters of the two fixed rings 913 can prevent water from accumulating in the fixed groove 203, thereby improving the working efficiency of the water purification equipment. The guide slope 914 provided can prevent water from accumulating on the top of the fixed ring 913, further improving the filtration efficiency of the purification equipment.

[0049] Sealing pads can be set on both sides of the sealing groove 202 to prevent water from flowing out through the sealing groove 202. The cylinder 204 has the characteristic of rapid response and can quickly realize the pushing action of the sealing plate 201. Even under high pressure, the sealing operation can be quickly completed to ensure the stable operation of the sealing mechanism. At the same time, compared with some complex sealing systems, through the simple linkage of the cylinder 204 and the sealing plate 201, the sealing effect is achieved effectively and simply, the structure is simplified, and it is beneficial to reduce the manufacturing cost and maintenance cost. The sealing plate 201 is slidably connected to the inner wall of the sealing groove 202 to ensure the sealing of the sealing groove 202 (it should be noted that under normal circumstances, the internal flow area of ​​the stop valve 301 is small. If the stop valve 301 is used to seal the inside of the first diverter pipe 105, it is more likely to be blocked under normal working conditions. Therefore, this embodiment preferably uses the cylinder 204 to push the sealing plate 201).

[0050] When the interior of the first diverter pipe 105 is sealed by the sealing plate 201, water will accumulate on the top of the sealing plate 201 and generate water pressure. When the water pressure reaches a certain level, the sealing plate 201 may be deformed. In order to avoid this situation, a diverter mechanism is provided on one side of the first diverter pipe 105. The diverter mechanism includes a second diverter pipe 3 and a stop valve 301. The second diverter pipe 3 is arranged on the side of the first diverter pipe 105, and one end is connected to the interior of the first diverter pipe 105. The second diverter pipe 3 is arranged on the top of the sealing plate 201, and the other end of the second diverter pipe 3 is connected to the filter chamber 103 connected to another first diverter pipe 105. The stop valve 301 is arranged on the second diverter pipe 3, and the other first diverter pipe 105 is provided with the same diverter mechanism. Under normal circumstances, the stop valve 301 is in a normally closed state. The stop valve 301 can open or close the second diverter pipe 3, thereby controlling the passage of water.

[0051] When the interior of the first diversion pipe 105 is sealed, the staff can open the stop valve 301, and the water accumulated on the sealing plate 201 will enter the filter chamber 103 on the other side through the second diversion pipe 3, thereby reducing the pressure on the top of the sealing plate 201 and increasing the service life of the sealing plate 201.

[0052] refer to Figure 5 , Figure 7-9 , both sides of the filter chamber 103 are provided with fixed plates 4, and the fixed plates 4 are in an "L"-shaped structure. Both sides of the filter screen 104 are provided with mounting frames 401, and each mounting frame 401 is provided with a fixed block 402 on the side away from the filter screen 104. The bottom of each fixed block 402 is respectively abutted against the corresponding fixed plate 4, and the width of the fixed block 402 is greater than the width of the fixed plate 4. The other two sides of the filter chamber 103 are provided with a slot 403, and the fixed block 402 is provided with a slide groove 404. Both sides of the slide groove 404 are provided with a block 405 that is engaged with the corresponding slot 403, and the block 405 is slidably connected to the inner wall of the slide groove 404. A connecting rod mechanism for disengaging each block 405 from the slot 403 is provided on the side of the box door 107 close to the filter chamber 103, and when the staff opens the box door 107, the connecting rod mechanism can also lift the fixed block 402 to the opening 106.

[0053] By engaging the block 405 with the slot 403, the impact of the water flow on the filter 104 can be reduced, and the shaking can be reduced, thereby improving the stability of the filter 104 during the water filtering process. Through the setting of the connecting rod 5 mechanism, when the staff opens the box door 107, the setting of the connecting rod 5 mechanism will automatically lift the filter 104 to the opening 106, so that the staff can clean the impurities on the filter 104 and the operation is convenient.

[0054] Specifically, the connecting rod mechanism includes a connecting rod 5, a third gear 501, a third rack 502, and a lifting plate 503. The third gear 501 is arranged in the slide groove 404 and is rotatably connected to the inside of the slide groove 404. Screws 504 are provided on both sides of the third gear 501, and the screws 504 on both sides are respectively threadedly connected to the corresponding clamping blocks 405. The screw 504 is fixedly connected to the third gear 501. A rotating block 5011 is fixedly connected to the inside of the slide groove 404. The rotating block 5011 is used to support the screw 504, and the screw 504 is rotatably connected to the rotating block 5011, and the clamping block 405 is slidably connected to the inner wall of the slide groove 404, and the third gear 501 is rotatably connected to the rotating block 5011.

[0055] The cross section of the block 405 and the slot 403 is in a square structure. The square-structured block 405 can increase the contact area with the slot 403, thereby improving the fixing effect. At the same time, the square-structured block 405 can contact the inner wall of the slide slot 404 to prevent the block 405 from radially rotating when the screw 504 rotates, thereby improving the stability of the movement of the block 405.

[0056] A lifting groove 505 is provided on the fixed block 402, one side of the third rack 502 is arranged in the lifting groove 505 and is slidably connected to the inner wall of the lifting groove 505, and the third rack 502 is meshed with the third gear 501, the lifting plate 503 is arranged at the bottom of the third rack 502, and is fixedly connected to the third rack 502, and abuts against the bottom of the fixed block 402, one end of the connecting rod 5 is rotatably connected to the box door 107, and the other end of the connecting rod 5 is rotatably connected to the top of the third rack 502.

[0057] When the staff opens the box door 107, the third rack 502 moves toward the opening 106. Since the third rack 502 is meshed with the third gear 501, the third gear 501 rotates, driving the screws 504 on both sides to rotate, so that the block 405 is separated from the slot 403; the pitch of the screw 504 can be selected to be large, so that the third gear 501 only needs to rotate a few circles, and the block 405 will be separated from the slot 403; at the same time, as the third rack 502 rises, the lifting plate 503 also rises; when the lifting plate 503 contacts the bottom of the fixed block 402, the lifting plate 503 Drive the fixed block 402 to move toward the opening 106, and then move the filter 104 to the opening 106. It should be noted here that the objects that need to be lifted include the fixed block 402, the mounting frame 401, and the filter 104. The gravity exerted on these objects in combination is greater than the resistance of the meshing of the third gear 501 and the third rack 502. Therefore, when the third rack 502 and the third gear 501 move, the fixed block 402 itself will be affected by gravity and remain motionless (a counterweight block 915 can be added to the top of the fixed block 402 to increase the weight of the fixed block 402 itself).

[0058] Referring to 10-12, in order to prevent the fixed block 402 from shifting while rising, a first limit groove 5012 is set on both sides of the filter chamber 103, and a first limit block 5013 is set on the top of the fixed block 402. One side of the first limit block 5013 is slidingly connected to the inner wall of the first limit groove 5012. The cross-sections of the first limit block 5013 and the first limit groove 5012 are both square structures. The square structure can prevent the first limit block 5013 from rotating in the first limit groove 5012, and can ensure that the first limit block 5013 always maintains the correct direction, thereby improving the stability of the movement of the fixed block 402.

[0059] In this embodiment, reference Figure 8 , Fig. 9 , Fig.17, the filter chamber 103 is provided with an extrusion groove 6 on one side opposite to each slot 403, and the extrusion groove 6 corresponds to the side of the filter screen 104, a plurality of first elastic members 601 are provided inside the extrusion groove 6, and one side of each first elastic member 601 is fixedly connected to the side of the extrusion groove 6 away from the filter screen 104, one end of each first elastic member 601 abuts against the side of the filter screen 104 through the extrusion plate 602, and one end of each first elastic member 601 is fixedly connected to the extrusion plate 602, and the first elastic member 601 is fixedly connected to the extrusion plate 602. The elastic member 601 is a cylindrical compression spring, the side of the filter screen 104 is in contact with the extrusion plate 602, the filter screen 104 and the mounting frame 401 are both slidably connected to the inner wall of the extrusion groove 6, a first sliding groove 603 is provided on the fixed block 402, a first sliding block 604 is provided at the bottom of the mounting frame 401, the first sliding block 604 is slidably connected to the inner wall of the first sliding groove 603, and a driving mechanism is provided at the bottom of the filter cavity 103 to enable the filter screen 104 and the mounting frame 401 to compress the first elastic member 601 back and forth.

[0060] When the filter 104 is impacted by water, the first elastic member 601 can absorb part of the vibration, thereby increasing the service life of the filter 104. The side of the filter 104 is connected to the plurality of first elastic members 601 through an extrusion plate 602, which can increase the contact area between the side of the filter 104 and the plurality of first elastic members 601, so that the force can be evenly distributed on the first elastic member 601 through the extrusion plate 602, thereby extending the service life of the first elastic member 601. At the same time, this connection method avoids the extrusion plate 602 from directly contacting the side of the filter 104, so that the filter 104 can move freely up and down.

[0061] Specifically, refer to Fig.11 , Fig.12 , Fig.16 , Fig.21 , guide plates 7 are provided on the opposite sides of the two fixed blocks 402, and the guide plates 7 are fixedly connected to the corresponding fixed blocks 402, and each guide plate 7 is arranged at the bottom of the corresponding fixed block 402, and a rotating groove 701 is provided on the side of the filter chamber 103 close to the first diversion pipe 105, and the rotating groove 701 is rotatably connected with a rotating disk 703 through a first rotating shaft 702, and the rotating disk 703 is fixedly connected to the first rotating shaft 702, and the first rotating shaft 702 is rotatably connected to the inner wall of the rotating groove 701, and a plurality of arc grooves 704 for receiving water are provided on the rotating disk 703, and the arc grooves 704 are circumferentially arranged with the rotating disk 703 as the center, and the rotating disk 703 is arranged between the two guide plates 7 and at the bottom of the two guide plates 7, and the rotating disk 703 drives the driving mechanism to move through the conveyor belt wheel group.

[0062] refer to Fig.14 , Fig.15 , Fig.16 , Fig.17 , Fig. 20The driving mechanism includes a first rack 8 and a first gear 801. The first rack 8 is arranged at the bottom of the first sliding block 604 and is fixedly connected to the first sliding block 604. The first gear 801 is rotatably connected to the inner wall of the filter chamber 103 through the second rotating shaft 802, and the first gear 801 is meshed with the first rack 8. The first gear 801 is provided with a plurality of through grooves 803 penetrating the first gear 801, and each through groove 803 is circumferentially arranged with the first gear 801 as the center. The first gear 801 is arranged at the bottom of the guide plate 7, and the second rotating shaft 802 is rotatably connected to the inner wall of the filter chamber 103, and the second rotating shaft 802 is linked to the conveyor belt wheel group.

[0063] The conveyor pulley group includes a first conveyor pulley 7021 and a second conveyor pulley 7022. A accommodating space 7023 is provided on one side of the filter chamber 103. The accommodating space 7023 and the rotating groove 701 are on the same side. The first rotating shaft 702 extends into the accommodating space 7023 and is rotatably connected to the side of the accommodating space 7023. The first conveyor pulley 7021 is arranged on one end of the first rotating shaft 702 in the accommodating space 7023 and is fixedly connected to the first rotating shaft 702. The second conveyor pulley 7022 is arranged on the second rotating shaft 802 and is fixedly connected to the second rotating shaft 802. The first conveyor pulley 7021 and the second conveyor pulley 7022 are connected by a conveyor belt 7024.

[0064] When the water flows into the filter chamber 103 through the first diversion pipe 105, the filter screen 104 will perform preliminary filtration on the water, and then the water will pass through the filter holes to the bottom of the filter screen 104. Under the action of the guide plate 7, a part of the water will flow into the arc groove 704 on the rotating disk 703. Due to the design of the arc groove 704, the water will move downward under the influence of gravity, so that the rotating disk 703 rotates clockwise, which is similar to the working principle of the waterwheel. The specific structure of the rotating disk 703 is referred to Fig.21When the rotating disk 703 rotates clockwise, it will drive the first rotating shaft 702 to rotate clockwise, and the first rotating shaft 702 will drive the first conveyor pulley 7021 to rotate clockwise, thereby driving the second conveyor pulley 7022 to rotate clockwise through the conveyor belt 7024, and the second conveyor pulley 7022 will drive the first gear 801 to rotate clockwise through the second rotating shaft 802. Since the first gear 801 is meshed with the first rack 8, the first gear 801 will drive the first sliding block 604 to slide and connect in the first sliding groove 603, so that the filter 104 is connected to the installation The side of the frame 401 squeezes the first elastic member 601 set on the right side. Since the first gear 801 is an incomplete gear, the first gear 801 will intermittently mesh with the first rack 8. When the first gear 801 meshes with the first rack 8, the filter 104 and the installation frame 401 will move in the direction of compressing the first elastic member 601. When the first gear 801 is not meshed with the first rack 8, the first elastic member 601 will restore its deformation and push the filter 104 and the installation frame 401 to the other side, so that the filter 104 can move back and forth in this reciprocating manner.

[0065] When the first elastic members 601 recover their deformation, the filter screen 104 and the mounting frame 401 may collide with the other side of the filter cavity 103 . Therefore, the same structure may be provided on the other side of the filter cavity 103 for buffering, thereby increasing the practical life of the filter screen 104 .

[0066] Moving the filter 104 back and forth can ensure that the water flow is evenly distributed on the surface of the filter 104, and can prevent pollutants from accumulating on the surface of the filter 104 to form blockages, thereby reducing the risk of blockages and improving the filtering effect. At the same time, the driving mechanism in this embodiment does not require an additional power source, which reduces the operating cost and maintenance cost of the equipment, improves the economic benefits of the equipment, and reduces energy consumption. The first gear 801 is set at the bottom of the guide plate 7 to prevent the water flow from corroding the first gear 801, thereby increasing the service life of the first gear 801.

[0067] When used for a long time, the first elastic member 601 will be subjected to repeated loading and releasing forces, which may cause the first elastic member 601 to undergo plastic deformation, that is, the shape or size of the first elastic member 601 will change, which may cause one side of the filter 104 to be embedded in the extrusion groove 6, thereby making it impossible for the filter 104 to be lifted. In order to avoid this situation, one side of the extrusion plate 602 is extended out of the extrusion groove 6, and the other side of the extrusion plate 602 is arranged in the extrusion groove 6, and one side of the extrusion plate 602 is abutted against the side of the filter 104. Extending one side of the extrusion plate 602 out of the extrusion groove 6 can allow the first elastic member 601 to undergo plastic deformation within a certain range, thereby improving the stability when lifting the filter 104.

[0068] In the above-mentioned connecting rod mechanism, block 405 and slot 403, when the staff closes the box door 107, the block 405 will be engaged with the slot 403, and can also play a positioning role, positioning the side of the filter 104 just to the side of the extrusion plate 602, so that the driving mechanism can be used repeatedly, thereby improving practicality.

[0069] In this embodiment, reference Figure 5 , Figure 6 , Fig.13 , Fig.14 In order to reduce the impact of water flow on the filter screen 104, a guide chamber 9 is provided on the side of the filter chamber 103 close to the first diverter pipe 105. The guide chamber 9 is arranged at the top of the filter chamber 103, and the guide chamber 9 is communicated with the inside of the filter chamber 103. A guide slope 901 is provided at the bottom of the guide chamber 9. The guide slope 901 is inclined from the side close to the water inlet pipe 101 to the side of the filter screen 104. One end of the first diverter pipe 105 extends into the guide chamber 9. When the high-pressure water flow enters the guide chamber 9 through the first diverter pipe 105, the guide slope 901 will buffer the high-pressure water flow, thereby reducing the pressure of the water flow on the filter screen 104, thereby improving the service life of the filter screen 104.

[0070] In order to avoid impurities remaining on the guide slope 901, a scraper mechanism is provided in the guide chamber 9, and the scraper mechanism includes a scraper 902, a second elastic member 903, a traction rope 904, a tightening wheel 905, a ratchet 906, and a straight ratchet rack 907. The scraper 902 is arranged in the filter chamber 103 and is slidably connected to the inner wall of the filter chamber 103. Guide grooves 908 are provided on both sides of the filter chamber 103, and the height of the guide grooves 908 is higher than the guide slope 901. Guide blocks 909 are provided on both sides of the scraper 902, and the guide blocks 909 are slidably connected to the inner wall of the guide groove 908. One end of the second elastic member 903 is fixedly connected to the guide block 909, and the other end of the second elastic member 903 is fixedly connected to the side of the guide groove 908 away from the scraper 902.

[0071] A tightening groove 910 is provided on the side of the filter chamber 103 close to the first diversion pipe 105, and the ratchet 906 is rotatably connected to the inner wall of the tightening groove 910 through the third rotating shaft 911. The straight ratchet rack 907 is movably connected to the bottom of the fixed block 402 and meshes with the ratchet 906. The tightening wheel 905 is arranged on the third rotating shaft 911 and fixedly connected to the third rotating shaft 911. A traction groove 912 is provided on the side of the guide groove 908 away from the scraper 902, and the traction groove 912 is connected to the tightening groove 910. The traction rope 904 is arranged in the traction groove 912, one end of the traction rope 904 is fixedly connected to the scraper 902, and the other end of the traction rope 904 is fixedly connected to the tightening wheel 905, and the traction rope 904 is arranged in the second elastic member 903.

[0072] By making the height of the guide groove 908 higher than the guide slope 901 , water entering from the first diversion pipe 105 can be prevented from flowing into the tightening groove 910 through the guide groove 908 , thereby improving the filtering efficiency of the water purification device.

[0073] refer to Figure 17-19 A mounting block 4021 is provided on one side of the fixing block 402 close to the tightening groove 910, and a telescopic groove 4022 is provided on one side of the mounting block 4021 close to the tightening groove 910. A plurality of third elastic members 4023 are provided at the bottom of the telescopic groove 4022, one end of the plurality of elastic members is fixedly connected to the side of the telescopic groove 4022, and the other end is fixedly connected to the straight ratchet rack 907, and both sides of the straight ratchet rack 907 are slidingly connected to the inner wall of the telescopic groove 4022, and a through opening 4026 is provided at the bottom of the telescopic groove 4022 for the ratchet 906 to pass through, so that when the straight ratchet rack 907 rises, the ratchet 906 can pass through smoothly, and the first elastic member 601, the second elastic member 903 and the third elastic member 4023 are all cylindrical compression springs.

[0074] When the staff pulls the fixed block 402 upward, the straight ratchet rack 907 arranged at the bottom of the fixed block 402 will engage with the ratchet 906 and drive the ratchet 906 to rotate counterclockwise, and the ratchet 906 will drive the tightening wheel 905 to rotate counterclockwise through the third rotating shaft 911. When the tightening wheel 905 rotates counterclockwise, the traction rope 904 will be wrapped around the surface of the tightening wheel 905 and reeled up. At the same time, the traction rope 904 will drive the scraper 902 to scrape off the impurities remaining on the guide slope 901 and leave the impurities on the surface of the filter screen 104, thereby facilitating cleaning by the staff. When the rack is disengaged from the ratchet 906, the second elastic member 903 will be reset, thereby resetting the scraper 902. The second diversion pipe 3 should extend between the scraper 902 and the filter chamber 103, so as to avoid the accumulation of impurities in the water flow behind the scraper 902, thereby reducing the cleaning dead corner of the scraper 902, thereby improving the scraping effect of the scraper 902.

[0075] When the fixed block 402 descends, since the straight ratchet rack 907 cannot engage with the ratchet wheel 906, the straight ratchet rack 907 will move in the direction of compressing the third elastic member 4023, so that the straight ratchet rack 907 can descend smoothly, and the block 405 driven by the connecting rod mechanism mentioned above can play a locking role to prevent the ratchet wheel 906 from being affected by the second elastic member 903 and driving the fixed block 402 to rise a certain distance, thereby improving the accuracy of the position of the fixed block 402 (it should be noted here that the gravity exerted on the fixed block 402 is greater than the elastic coefficient of the third elastic member 4023, so the fixed block 402 can abut against the fixed plate 4).

[0076] refer to Fig. 20In order to prevent the straight ratchet rack 907 from being offset during the movement, second limiting grooves 4024 are set on the upper and lower sides of the telescopic groove 4022, and second limiting blocks 4025 are set on the upper and lower sides of the straight ratchet rack 907, and each second limiting block 4025 is slidingly connected to the corresponding inner wall of the second limiting groove 4024. The second limiting blocks 4025 and the second limiting grooves 4024 can prevent the straight ratchet rack 907 from being misplaced or offset during the movement, thereby improving the stability of the movement of the straight ratchet rack 907, and at the same time, it can ensure that each third elastic member 4023 is subjected to uniform force, thereby increasing the service life of the third elastic member 4023.

[0077] Working principle:

[0078] 1. When the staff injects water into the water inlet pipe 101 through the water pump, the water will enter the corresponding diversion cavity 9 through the first diversion pipes 105 on both sides, and the water flow will fall into the filter cavity 103 under the influence of gravity and be preliminarily filtered through the filter screen 104.

[0079] 2. The water flow filtered by the filter screen 104 will be affected by the guide plates 7 on both sides of the bottom of the fixed block 402, and the water flow will be guided into the arc groove 704 on the rotating disk 703, so that the rotating disk 703 rotates clockwise. When the rotating disk 703 rotates clockwise, it will drive the first rotating shaft 702 to rotate clockwise, and the first rotating shaft 702 will drive the first transmission belt wheel 7021 to rotate clockwise, thereby driving the second transmission belt wheel 7022 to rotate clockwise through the transmission belt 7024, and the second transmission belt wheel will drive the first gear 801 to rotate clockwise through the second rotating shaft 802. Since the first gear 801 is meshed with the first rack 8, the first gear 801 will drive the first sliding block 604 to slide and connect in the first sliding groove 603, so as to achieve the desired effect. This causes the filter 104 and the side of the mounting frame 401 to squeeze the first elastic member 601 set on the right side. Since the first gear 801 is an incomplete gear, the first gear 801 will intermittently mesh with the first rack 8. When the first gear 801 meshes with the first rack 8, the filter 104 and the mounting frame 401 will move in the direction of compressing the first elastic member 601. When the first gear 801 is not meshed with the first rack 8, the first elastic member 601 will restore its deformation and push the filter 104 and the mounting frame 401 to the other side. The filter 104 can be moved back and forth in this reciprocating manner to avoid pollutants accumulating on the surface of the filter 104 to form blockages, thereby reducing the risk of blockages and improving the filtering effect.

[0080] 3. The water that has been initially filtered by the filter 104 will enter the purification box 108 through the water inlet 1081 for final filtration. First, the water will pass through the activated carbon plate 1082 layer, and then pass through the hollow ultrafiltration membrane 1083 and the negative ion layer 1084 respectively. Under the action of the negative ion generator 1085, a large amount of negative ions are generated, and the negative ions react with water molecules to improve the water quality or purify the water. Finally, the water will enter the reverse osmosis membrane layer 1086 from the left channel of the negative ion layer 1084, and finally be discharged through the outlet pipe 102. The reverse osmosis membrane layer 1086 is specifically responsible for removing bacteria and viruses in the water, thereby ensuring the purity of the water.

[0081] 4. When the staff needs to clean the impurities on the surface of the filter screen 104 , the cylinder 204 is first started, and the telescopic end of the cylinder 204 will drive the sealing plate 201 to seal the inside of the first diversion pipe 105 .

[0082] 5. Then open the stop valve 301 to allow the water accumulated on the sealing plate 201 to flow through the second diversion pipe 3 into the filter chamber 103 on the other side.

[0083] 6. Finally, the box door 107 is opened. Under the action of the connecting rod 5, the third rack 502 moves toward the direction of the opening 106. Since the third rack 502 is meshed with the third gear 501, the third gear 501 rotates, driving the screws 504 on both sides to rotate, so that the block 405 is disengaged from the slot 403.

[0084] At the same time, as the third rack 502 rises, the lifting plate 503 also rises accordingly; when the lifting plate 503 contacts the bottom of the fixing block 402 , the lifting plate 503 drives the fixing block 402 to move toward the opening 106 , thereby moving the filter screen 104 to the opening 106 .

[0085] 7. When the fixed block 402 rises, the straight ratchet rack 907 arranged at the bottom of the fixed block 402 will mesh with the ratchet wheel 906 and rotate counterclockwise, and the ratchet wheel 906 will drive the tightening wheel 905 to rotate counterclockwise through the third rotating shaft 911. When the tightening wheel 905 rotates, the traction rope 904 will be wound around the surface of the tightening wheel 905 and be wound up. At the same time, the traction rope 904 will drive the scraper 902 to scrape off the impurities remaining on the guide slope 901 and leave the impurities on the surface of the filter screen 104, so as to facilitate the cleaning of the staff. When the straight ratchet rack 907 is separated from the ratchet wheel 906, the second elastic member 903 will be reset, thereby bringing the scraper 902 to reset;

[0086] 8. When the staff has cleaned the impurities on the surface of the filter screen 104, they only need to lower the box door 107. Under the action of gravity, the fixed block 402 will always be in contact with the lifting plate 503 until the bottom of the fixed block 402 abuts against the fixed plate 4; when the fixed block 402 abuts against the fixed plate 4, the lifting plate 503 will no longer be in contact with the bottom of the fixed block 402, and at the same time, the third rack 502 will drive the third gear 501 to rotate clockwise, and the third gear 501 will drive the screws 504 on both sides to rotate clockwise, so that the card block 405 is inserted into the card slot 403, thereby achieving fixation. At the same time, when the fixed block 402 descends, since the straight ratchet rack 907 cannot engage with the ratchet wheel 906, the straight ratchet rack 907 will move in the direction of compressing the third elastic member 4023, so that the straight ratchet rack 907 can descend smoothly.

[0087] Embodiment three:

[0088] Based on Example 2, refer to Fig.15 In this example, in order to prevent the fixed block 402 from being in a relative position with the teeth on the first gear 801 when driving the first rack 8 at the bottom of the mounting frame 401 to descend, resulting in the fixed block 402 being unable to abut against the fixed plate 4, one end of the second rotating shaft 802 is extended to the outside of the shell 1 and is rotatably connected to the shell 1, and a rotating block 8021 is provided on the side of the second rotating shaft 802 away from the shell 1 for rotating the second rotating shaft 802, and a transparent observation window is provided on the side of the shell 1 close to the second rotating shaft 802, so that the staff can observe the meshing of the first rack 8 and the second rack. When the first rack 8 is relative to the teeth on the first gear 801, the staff can rotate the rotating block 8021 so that the first rack 8 can mesh with the first gear 801, so that the fixed block 402 can abut against the fixed plate 4, thereby improving practicality.

[0089] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
