DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1: Reference Figure 1-5 , a direct drinking water purification module, comprising a shell 1, a water inlet pipe 101 and a water outlet pipe 102 are provided on the shell 1, and a multi-layer filter cake 103 is provided in the water outlet pipe 102, a first annular filter screen 2 and a second filter screen 3 are fixedly connected in the shell 1, the aperture of the filtering hole of the first filter screen 2 is larger than the aperture of the filtering hole of the second filter screen 3, a driven impeller 4 is rotatably installed in the first filter screen 2, a partition plate 5 is fixedly connected in the shell 1, the partition plate 5 abuts against the end surface of the second filter screen 3, a rotating block 6 is rotatably installed on the partition plate 5, a transmission shaft 7 is coaxially fixedly connected to the rotating block 6, the transmission shaft 7 is coaxially fixedly connected to the driven impeller 4, a guide wheel 8 is rotatably installed on the transmission shaft 7, a hose 9 is matched and installed on the guide wheel 8, both ends of the hose 9 pass through the rotating block 6 and slide in cooperation with the rotating block 6, and a first accommodating port 901 and a second accommodating port 902 are provided on the hose 9.

[0030] When the water purification module is in use, water is input into the shell 1 from the water inlet pipe 101. The water in the shell 1 is filtered by the first filter screen 2 and the second filter screen 3 and then input into the water outlet pipe 102. After the multi-layer filter cake 103 in the water outlet pipe 102 filters the water twice, the water is discharged after filtering.

[0031] The steps for water filtration are as follows:

[0032] First of all, since the mesh number of the first filter 2 is smaller than the mesh number of the second filter 3, the first filter 2 will first perform an initial screening on the water body to filter out large particles of impurities such as sand, gravel, rust fragments, etc. in the water body. The filtered impurities are located outside the first filter 2. When cleaning, you only need to open the cover on the top of the shell 1 to clean up the large particles of impurities outside the first filter 2.

[0033] Afterwards, the water body enters the second filter screen 3 . Since the mesh size of the second filter screen 3 is large, the water body can be finely screened. After being filtered by the second filter screen 3 , small particles of impurities and flocs in the water body will be filtered out by the second filter screen 3 .

[0034] Finally, the water enters the outlet pipe 102, in which a multi-layer filter cake 103 is arranged. The filter cake 103 is composed of a filter cotton layer, an activated carbon layer and a microporous filter membrane in sequence, which can adsorb and filter odors, pigments and bacteria in the water, thereby achieving the purpose of water purification.

[0035] In the process of filtering the water body by the second filter 3, the small particles and floccules filtered out of the water body will adhere to the inner wall of the second filter 3, affecting the filtering rate of the water body. Therefore, the cleaning method for the inside of the second filter 3 is as follows:

[0036] When water enters the second filter screen 3 from the first filter screen 2, the water will drive the impeller 4 to rotate. The rotation of the impeller 4 will drive the transmission shaft 7 and the rotating block 6 to rotate. During the rotation of the transmission shaft 7 and the rotating block 6, the hose 9 will be driven to rotate. The rotation of the hose 9 will drive the first receiving port 901 and the second receiving port 902 to rotate inside the second filter screen 3, thereby changing the opening direction of the first receiving port 901 and the second receiving port 902.

[0037] In addition, since the hose 9 is slidably matched with the rotating block 6 , both ends of the hose 9 can slide in the rotating block 6 , and when the hose 9 slides in the rotating block 6 , the height of the first accommodating opening 901 and the second accommodating opening 902 in the second filter 3 will be changed.

[0038] Therefore, the first receiving opening 901 and the second receiving opening 902 change their own heights during the rotation in the second filter screen 3 , so that the interior of the second filter screen 3 can be completely scanned.

[0039] When the first receiving port 901 and the second receiving port 902 are scanning the inside of the second filter 3, negative pressure is applied to both ends of the hose 9, and the first receiving port 901 and the second receiving port 902 will also generate negative pressure. Under the action of the negative pressure, the first receiving port 901 and the second receiving port 902 will suck the small particles and flocs inside the second filter 3, thereby cleaning the impurities attached to the inner wall of the second filter 3.

[0040] Embodiment 2: Figure 3-8 As shown, a sewage chamber 17 is fixedly connected to the bottom of the shell 1, and a third filter screen 501 is provided on the partition 5 to connect the sewage chamber 17 with the second filter screen 3, and the aperture of the filter hole of the third filter screen 501 is smaller than the aperture of the filter hole of the second filter screen 3. A sealing cover 16 is rotatably installed on the sewage chamber 17, and the sealing cover 16 is connected to the rotating block 6 by a screw 15. The first bellows 23 and the second bellows 24 are fixedly connected to the sealing cover 16, one end of the hose 9 is connected to the first bellows 23, and the other end of the hose 9 is connected to the second bellows 24.

[0041] During the rotation of the rotating block 6 , the rotating block 6 will drive the sealing cover 16 to rotate synchronously through the screw 15 . During this process, the first bellows 23 and the second bellows 24 are driven to axially expand and contract to generate negative pressure at both end ports of the hose 9 .

[0042] like Figure 4 and Fig.12 As shown, an internal threaded tube 21 is fixedly connected to the end face of the first corrugated tube 23, a reciprocating screw 18 is rotatably mounted on the rotating block 6, the reciprocating screw 18 is threadedly fitted in the internal threaded tube 21, a driven gear 19 is fixedly connected to the reciprocating screw 18, a ring gear 20 is fixedly connected to the partition plate 5, and the driven gear 19 cooperates with the ring gear 20.

[0043] During the rotation of the rotating block 6, the reciprocating screw 18 is driven to revolve orbitally, and during the revolution of the reciprocating screw 18, the driven gear 19 is driven to revolve orbitally. Since the driven gear 19 is meshed with the ring gear 20, the driven gear 19 is driven by the ring gear 20 to rotate during the revolution of the driven gear 19. The rotation of the driven gear 19 drives the reciprocating screw 18 to rotate. During the rotation of the reciprocating screw 18, the internal threaded tube 21 is driven to perform linear reciprocating motion in the axial direction. The linear reciprocating motion of the internal threaded tube 21 drives the first corrugated tube 23 to extend and retract back and forth in the axial direction.

[0044] like Figure 3-4 As shown, a first drain pipe 231 is fixedly connected to the first bellows 23, a first valve plate 232 is hinged on the end surface of the first drain pipe 231 to control the opening and closing of the first drain pipe 231, and a second valve plate 233 is hinged inside the first bellows 23 to control the opening and closing of the port of the hose 9.

[0045] The first bellows 23 will increase or decrease the pressure inside the first bellows 23 during the axial expansion and contraction process, wherein:

[0046] When the pressure inside the first bellows 23 decreases, the second valve plate 233 opens under the pressure, and the first valve plate 232 closes the first sewage pipe 231; under the negative pressure inside the first bellows 23, the small particles and flocs in the second filter screen 3 are sucked into the first bellows 23 through the first receiving port 901 along with the water flow;

[0047] When the internal pressure of the first bellows 23 increases, the second valve plate 233 will close the port of the hose 9 under the action of pressure, and the first valve plate 232 will open under the action of pressure. Under the action of pressure, small particles of impurities and flocs contained in the first bellows 23 will be discharged into the sewage chamber 17 through the first sewage pipe 231.

[0048] like Figure 3-4 As shown, a compression spring 22 is provided on the rotating block 6 to apply axial elastic force to the second bellows 24, a second sewage pipe 241 is fixedly connected to the second sewage pipe 24, a third valve plate 242 is hinged on the second sewage pipe 241 to control the opening and closing of the second sewage pipe 241, and a fourth valve plate 243 is hinged in the second bellows 24 to control the opening and closing of the port of the hose 9.

[0049] During the process of the first bellows 23 expanding and contracting back and forth in the axial direction, a pulling force may be generated on the hose 9, and the pulling force is applied to the second bellows 24 through the hose 9. The elastic force applied by the compression spring 22 on the second bellows 24 is opposite to the pulling force applied by the hose 9. Therefore, under the action of both the pulling force of the hose 9 and the elastic force of the compression spring 22, the second bellows 24 will also expand and contract back and forth in the axial direction.

[0050] As mentioned above, the pressure inside the second bellows 24 increases or decreases during the axial expansion and contraction process of the second bellows 24, wherein:

[0051] When the pressure inside the second bellows 24 decreases, the fourth valve plate 243 opens under the pressure, and the third valve plate 242 closes the second sewage pipe 241; under the negative pressure inside the second bellows 24, the small particles and flocs in the second filter screen 3 are sucked into the second bellows 24 through the second receiving port 902 along with the water flow;

[0052] When the internal pressure of the second bellows 24 increases, the fourth valve plate 243 will close the port of the hose 9 under the action of pressure, and the third valve plate 242 will open under the action of pressure. Under the action of pressure, small particles of impurities and flocs contained in the second bellows 24 will be discharged into the sewage chamber 17 through the second sewage pipe 241.

[0053] To summarize, through the axial reciprocating telescopic motion of the first bellows 23 and the second bellows 24, the hose 9 can be driven to slide in the rotating block 6, so that the first accommodating port 901 and the second accommodating port 902 can move axially in the second filter 3 to complete the scanning work, and negative pressure can also be generated at both ends of the hose 9, so that small particles of impurities and flocs in the second filter 3 can be drawn into the sewage chamber 17 along with the water body. The water body drawn into the sewage chamber 17 can return to the second filter 3 through the third filter 501, and the small particles of impurities and flocs will be collected in the sewage chamber 17 to complete the cleaning work of the second filter 3 and prevent the small particles of impurities and flocs from adhering to the inner wall of the second filter 3 and causing the filter holes to be blocked.

[0054] Embodiment 3: Figure 7-10 As shown, a vibration structure is provided on the partition 5 to vibrate the second filter 3, and the vibration structure includes a plurality of guide rails 10, and the plurality of guide rails 10 are on the same circumference and fixed on the partition 5 at intervals, and a mounting frame 12 is fixedly connected to the rotating block 6, and a slide rod 13 is slidably matched on the mounting frame 12, and a vibration hammer 11 is fixedly connected to the slide rod 13, and a spring 14 is provided on the mounting frame 12 to apply elastic force to the vibration hammer 11, and the spring 14 is always in a compressed state, and the vibration hammer 11 is slidably matched with the guide rail 10.

[0055] During the rotation of the rotating block 6, the rotating block 6 will drive the vibration hammer 11 to rotate through the mounting frame 12 and the sliding rod 13. Under the elastic force of the spring 14, the vibration hammer 11 will rotate against the guide rail 10. When the vibration hammer 11 rotates to the gap between the two guide rails 10, the vibration hammer 11 will strike the second filter screen 3 under the elastic force of the spring 14, causing the second filter screen 3 to vibrate, so as to shake off the small particles and flocs attached to the inside of the second filter screen 3, thereby improving the cleaning quality.

[0056] Working principle and workflow:

[0057] When the water purification module is in use, water is input into the shell 1 from the water inlet pipe 101. The water in the shell 1 is filtered by the first filter screen 2 and the second filter screen 3 and then input into the water outlet pipe 102. After the multi-layer filter cake 103 in the water outlet pipe 102 filters the water twice, the water is discharged after filtering.

[0058] The steps for water filtration are as follows:

[0059] First of all, since the mesh number of the first filter 2 is smaller than the mesh number of the second filter 3, the first filter 2 will first perform an initial screening on the water body to filter out large particles of impurities such as sand, gravel, rust fragments, etc. in the water body. The filtered impurities are located outside the first filter 2. When cleaning, you only need to open the cover on the top of the shell 1 to clean up the large particles of impurities outside the first filter 2.

[0060] Afterwards, the water body enters the second filter screen 3 . Since the mesh size of the second filter screen 3 is large, the water body can be finely screened. After being filtered by the second filter screen 3 , small particles of impurities and flocs in the water body will be filtered out by the second filter screen 3 .

[0061] Finally, the water enters the outlet pipe 102, in which a multi-layer filter cake 103 is arranged. The filter cake 103 is composed of a filter cotton layer, an activated carbon layer and a microporous filter membrane in sequence, which can adsorb and filter odors, pigments and bacteria in the water, thereby achieving the purpose of water purification.

[0062] In the process of filtering the water body by the second filter 3, the small particles and floccules filtered out of the water body will adhere to the inner wall of the second filter 3, affecting the filtering rate of the water body. Therefore, the cleaning method for the inside of the second filter 3 is as follows:

[0063] When water enters the second filter screen 3 from the first filter screen 2, the water will drive the impeller 4 to rotate. The rotation of the impeller 4 will drive the transmission shaft 7 and the rotating block 6 to rotate. During the rotation of the transmission shaft 7 and the rotating block 6, the hose 9 will be driven to rotate. The rotation of the hose 9 will drive the first receiving port 901 and the second receiving port 902 to rotate inside the second filter screen 3, thereby changing the opening direction of the first receiving port 901 and the second receiving port 902.

[0064] During the rotation of the rotating block 6, the reciprocating screw 18 is driven to revolve, and during the reciprocating screw 18 revolves, the driven gear 19 is driven to revolve. Since the driven gear 19 is meshed with the ring gear 20, the driven gear 19 is driven to rotate by the ring gear 20 during the reciprocating process. The self-rotation of the driven gear 19 drives the reciprocating screw 18 to rotate. During the self-rotation of the reciprocating screw 18, the internal threaded tube 21 is driven to reciprocate linearly in the axial direction. The linear reciprocating motion of the internal threaded tube 21 drives the first bellows 23 to extend and retract back and forth in the axial direction.

[0065] The first bellows 23 will increase or decrease the pressure inside the first bellows 23 during the axial expansion and contraction process, wherein:

[0066] When the pressure inside the first bellows 23 decreases, the second valve plate 233 opens under the pressure, and the first valve plate 232 closes the first sewage pipe 231; under the negative pressure inside the first bellows 23, the small particles and flocs in the second filter screen 3 are sucked into the first bellows 23 through the first receiving port 901 along with the water flow;

[0067] When the internal pressure of the first bellows 23 increases, the second valve plate 233 will close the port of the hose 9 under the action of pressure, and the first valve plate 232 will open under the action of pressure. Under the action of pressure, small particles of impurities and flocs contained in the first bellows 23 will be discharged into the sewage chamber 17 through the first sewage pipe 231.

[0068] During the process of the first bellows 23 expanding and contracting back and forth in the axial direction, a pulling force may be generated on the hose 9, and the pulling force is applied to the second bellows 24 through the hose 9. The elastic force applied by the compression spring 22 to the second bellows 24 is opposite to the pulling force applied by the hose 9. Therefore, under the action of both the pulling force of the hose 9 and the elastic force of the compression spring 22, the second bellows 24 will also expand and contract back and forth in the axial direction.

[0069] As mentioned above, the pressure inside the second bellows 24 increases or decreases during the axial expansion and contraction process of the second bellows 24, wherein:

[0070] When the pressure inside the second bellows 24 decreases, the fourth valve plate 243 opens under the pressure, and the third valve plate 242 closes the second sewage pipe 241; under the negative pressure inside the second bellows 24, the small particles and flocs in the second filter screen 3 are sucked into the second bellows 24 through the second receiving port 902 along with the water flow;

[0071] When the internal pressure of the second bellows 24 increases, the fourth valve plate 243 will close the port of the hose 9 under the action of pressure, and the third valve plate 242 will open under the action of pressure. Under the action of pressure, small particles of impurities and flocs contained in the second bellows 24 will be discharged into the sewage chamber 17 through the second sewage pipe 241.

[0072] Through the axial reciprocating telescopic motion of the first bellows 23 and the second bellows 24, the hose 9 can be driven to slide in the rotating block 6, so that the first accommodating port 901 and the second accommodating port 902 can move axially in the second filter 3 to complete the scanning work and generate negative pressure at both ends of the hose 9.

[0073] During the process of the first receiving port 901 and the second receiving port 902 scanning the inside of the second filter screen 3, negative pressure is applied to both ends of the hose 9, and the first receiving port 901 and the second receiving port 902 will also generate negative pressure. Under the action of the negative pressure, the first receiving port 901 and the second receiving port 902 will suck the small particles of impurities and flocs inside the second filter screen 3, thereby cleaning up the impurities attached to the inner wall of the second filter screen 3, so that the small particles of impurities and flocs in the second filter screen 3 can be sucked into the sewage chamber 17 along with the water body. The water body sucked into the sewage chamber 17 can return to the second filter screen 3 through the third filter screen 501, and the small particles of impurities and flocs will be collected in the sewage chamber 17 to complete the cleaning of the second filter screen 3 and prevent the filter holes from being blocked due to the attachment of small particles of impurities and flocs to the inner wall of the second filter screen 3.

[0074] During the rotation of the rotating block 6, the rotating block 6 will drive the vibration hammer 11 to rotate through the mounting frame 12 and the sliding rod 13. Under the elastic force of the spring 14, the vibration hammer 11 will rotate against the guide rail 10. When the vibration hammer 11 rotates to the gap between the two guide rails 10, the vibration hammer 11 will strike the second filter screen 3 under the elastic force of the spring 14, causing the second filter screen 3 to vibrate, so as to shake off the small particles and flocs attached to the inside of the second filter screen 3, thereby improving the cleaning quality.
