Description

Technical Field

[0001] This invention relates to the field of portable water purifiers, and more specifically, to a filter self-cleaning structure for a portable water purifier based on dual self-powered systems. Background Technology

[0002] This outdoor water purifier manually purifies surface water such as river, lake, sea, rainwater, and groundwater into potable water. It utilizes replaceable pre-filter ultrafiltration membrane elements and reverse osmosis elements for multi-stage filtration, with a manual pump providing the necessary operating pressure. Because the reverse osmosis membrane requires appropriate pressure to operate, the manual pump, the core technology of this product, employs a patented dual-plunger structure to generate higher pressure and improve water output efficiency. Product advantages: lightweight, compact, and easy to carry. The patented dual-plunger manual pump is highly efficient, corrosion-resistant, and has a long lifespan. The unique button-type venting and draining design easily and quickly expels air from the pump, improving water lifting and output efficiency. It can operate normally both vertically and at an angle; convenient and flexible to carry and use. Both ultrafiltration and reverse osmosis membrane elements are the same size and can be replaced. The product is suitable for outdoor activities and drinking water supply in various emergency situations, such as wilderness survival, outdoor adventure and natural disasters. It can be equipped with large and small boats, yachts and life rafts on rivers and lakes to provide emergency drinking water. It can treat surface water and groundwater such as river and lake water, rainwater, and fishpond water.

[0003] When using a water purifier to purify wastewater, filtration is usually employed. In addition, due to the high requirements for water quality, a semi-permeable membrane is generally used for wastewater filtration. During the filtration process, a lot of impurities will adhere to the surface of the semi-permeable membrane. Since the semi-permeable membrane is made of flexible material, scraping it during cleaning will damage the semi-permeable membrane, thus preventing it from filtering.

[0004] Therefore, improvements are made to this, proposing a filter self-cleaning structure for a portable water purifier based on dual self-powered power supply. Summary of the Invention

[0005] The purpose of this invention is to address the problem of cleaning impurities adhering to the surface of semi-permeable membranes during the current wastewater filtration process.

[0006] To achieve the above-mentioned objectives, this invention provides a filter self-cleaning structure for a portable water purifier based on dual self-powered systems, thereby solving the aforementioned problems.

[0007] The application is as follows:

[0008] The system includes an outer shell, with a reverse osmosis filter one and a reverse osmosis filter two fixedly connected to the bottom surface of the inner shell. Each reverse osmosis filter one and reverse osmosis filter two includes a sleeve. A connecting block is connected to the lower surface of the sleeve, and a filter bucket is connected to the lower surface of the connecting block. A reverse osmosis bucket is fixedly connected to the inner wall of the filter bucket, and a baffle is fixedly connected to the inner wall of the reverse osmosis bucket. A sliding groove is provided between the reverse osmosis bucket and the baffle. A slider is slidably connected to the inner wall of the sliding groove. A spring is fixedly connected to one side of the slider, and a reverse osmosis plate one is fixedly connected to the other end of the spring. The reverse osmosis plate one includes a telescopic ring and a threaded ring on one side. The threaded ring is threadedly connected to the reverse osmosis bucket. A reverse osmosis plate two is rotatably connected to the reverse osmosis plate one near the spring surface. Both reverse osmosis plate one and reverse osmosis plate two are composed of a solid plate and a filter plate.

[0009] An electric telescopic rod is fixedly connected to the reverse osmosis plate away from the spring surface. A reduction motor is fixedly connected to the end of the electric telescopic rod away from the spring. A fixing ring is fixedly connected to the reverse osmosis tank away from the spring surface. The fixing ring is connected to the outlet.

[0010] The spring passes through the second reverse osmosis plate and is fixedly connected to the first reverse osmosis plate. Multiple casters are fixedly connected to the other side of the outer shell, and a pull rod is slidably connected to the outer shell away from the caster surface.

[0011] A rocker arm is provided near the pull rod surface of the outer casing. The rocker arm passes through the outer casing and is rotatably connected to the power generation component. The power generation component is located on the inner surface of the battery.

[0012] A solar panel is attached to the outer surface of the battery, and the solar panel is folded and installed on the outer surface of the battery.

[0013] As a preferred technical solution of this application, a pretreatment filter one, a pretreatment filter two, a post-filter and a self-cleaning filter are fixedly connected to the bottom surface of the outer shell.

[0014] As a preferred technical solution of this application, a lid is hinged to the upper surface of the outer shell, and indicator lights and operation buttons are respectively provided on the side of the outer shell. A solar interface and a USB interface are provided on the side of the outer shell away from the indicator lights.

[0015] As a preferred technical solution of this application, both the filter tank and the reverse osmosis tank contract from the side near the connecting block to the other end, and the contracted end is connected to the outlet.

[0016] As a preferred technical solution of this application, the output end of the pretreatment filter one is connected to the pretreatment filter two, the output end of the pretreatment filter two is connected to the post-filter, the output end of the post-filter is connected to the self-cleaning filter, and the output end of the self-cleaning filter is connected to the reverse osmosis filter one and the reverse osmosis filter two respectively.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] In the scheme of this application:

[0019] 1. When cleaning reverse osmosis plate one and reverse osmosis plate two, the geared motor can be turned on. After the geared motor is turned on, the electric telescopic rod will rotate, which will in turn rotate reverse osmosis plate one. During the rotation of reverse osmosis plate one, its core plate part will fit into the filter plate part of reverse osmosis plate two, thereby achieving a seal between reverse osmosis plate one and reverse osmosis plate two. Then the electric telescopic rod will retract, which will drive the spring and slider to slide. During the sliding process, the slider will drive the gas inside the slide groove to push, and the pushed gas will clean the flexible filter plate.

[0020] 2. During filtration, the wastewater undergoes primary pretreatment through pretreatment filter one, followed by secondary pretreatment through pretreatment filter two. After that, the wastewater enters the post-filter and self-cleaning filter for filtration, removing most of the impurities inside the wastewater. Finally, it enters reverse osmosis filter one and reverse osmosis filter two for osmosis filtration to achieve wastewater purification. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0038] As mentioned in the background section, during wastewater filtration, it is difficult to clean the impurities adhering to the surface of flexible semi-permeable membranes.

[0039] To address this technical problem, the present invention provides a filter self-cleaning structure for a portable water purifier based on dual self-powered power supply, which is used to clean the surface of a semi-permeable membrane during the filtration process.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] A self-cleaning structure for a portable water purifier based on dual self-powered systems specifically includes a housing 1. A reverse osmosis filter 101 and a reverse osmosis filter 102 are fixedly connected to the bottom surface of the housing 1. Both the reverse osmosis filter 101 and the reverse osmosis filter 102 include a sleeve 103. A connecting block 104 is connected to the lower surface of the sleeve 103, and a filter tank 105 is connected to the lower surface of the connecting block 104. A reverse osmosis tank 106 is fixedly connected to the inner wall of the filter tank 105, and a baffle 107 is fixedly connected to the inner wall of the reverse osmosis tank 106. A groove 108 is provided between the baffles 107. A slider 109 is slidably connected to the inner wall of the groove 108. A spring 110 is fixedly connected to one side of the slider 109. A reverse osmosis plate 111 is fixedly connected to the other end of the spring 110. The side of the reverse osmosis plate 111 includes a telescopic ring 112 and a threaded ring 113. The threaded ring 113 is threadedly connected to the reverse osmosis tank 106. A reverse osmosis plate 114 is rotatably connected to the reverse osmosis plate 111 near the surface of the spring 110. Both the reverse osmosis plate 111 and the reverse osmosis plate 114 are composed of a solid plate 115 and a filter plate 116.

[0044] An electric telescopic rod 201 is fixedly connected to the side of the reverse osmosis plate 111 away from the spring 110. A reduction motor 202 is fixedly connected to the end of the electric telescopic rod 201 away from the spring 110. A fixing ring 203 is fixedly connected to the side of the reverse osmosis tank 106 away from the spring 110. The fixing ring 203 is connected to the outlet.

[0045] Spring 110 passes through reverse osmosis plate 2 114 and is fixedly connected to reverse osmosis plate 111. Multiple casters 6 are fixedly connected to the other side of the outer shell 1. A pull rod 601 is slidably connected to the side of the outer shell 1 away from the casters 6.

[0046] A rocker arm 7 is provided on the surface of the outer casing 1 near the pull rod 601. The rocker arm 7 passes through the outer casing 1 and is rotatably connected to the power generation component. The power generation component is located on the inner surface of the battery 701.

[0047] A solar panel 8 is attached to the outer surface of the battery 701. The solar panel 8 is folded and installed on the outer surface of the battery 701.

[0048] When cleaning the reverse osmosis plate 111 and the reverse osmosis plate, the geared motor 202 can be turned on. After the geared motor 202 is turned on, it drives the electric telescopic rod 201 to rotate, which in turn drives the reverse osmosis plate 111 to rotate. During the rotation of the reverse osmosis plate 111, the solid plate 115 part of the reverse osmosis plate 114 and the filter plate 116 part are in contact, thereby achieving a seal between the reverse osmosis plate 111 and the reverse osmosis plate 114. Then the electric telescopic rod 201 retracts, which drives the spring 110 and the slider 109 to slide. During the sliding process, the slider 109 drives the gas inside the slide groove 108 to push, and the pushed gas cleans the flexible filter plate 116.

[0049] An electric telescopic rod 201, fixedly connected to the reverse osmosis plate 111 away from the spring 110, is used to control the stretching of the reverse osmosis plate 111 to form a negative pressure. A reduction motor 202, fixedly connected to the end of the electric telescopic rod 201 away from the spring 110, is used to drive the electric telescopic rod 201 to rotate. During the rotation, the electric telescopic rod 201 drives the reverse osmosis plate 111 to rotate and forms a misalignment with the reverse osmosis plate 114 so that a sealed environment is formed between the reverse osmosis plate 111 and the reverse osmosis plate 114, so as to clean the reverse osmosis plate 111 and the reverse osmosis plate 114.

[0050] The bottom surface of the outer casing 1 is fixedly connected to a pretreatment filter 4, a pretreatment filter 401, a post-filter 402, and a self-cleaning filter 403.

[0051] The first treatment filter, which is fixedly connected to the bottom of the outer casing 1, is used for primary filtration of sewage. The second treatment filter is used for secondary filtration of the sewage filtered by the primary filter. The post-filter 402 and the self-cleaning filter 403 circulate and purify the clean water to filter out most of the impurities inside the sewage.

[0052] The upper surface of the outer casing 1 is hinged with a cover 5. The sides of the outer casing 1 are respectively provided with an indicator light 501 and an operation button 502. The side of the outer casing 1 away from the indicator light 501 is provided with a solar interface 503 and a USB interface 504.

[0053] The hinged cover 5 on the upper surface of the outer casing 1 is used to isolate the outer casing 1. The indicator light 501 on the side of the outer casing 1 is used to indicate the sewage purification process to the operator. The operation button 502 on the side of the outer casing 1 is used to control the operation of the filter components inside the outer casing 1. The solar interface 503 and USB interface 504 on the side of the outer casing 1 away from the indicator light 501 are used to connect to the power output interface to realize solar power supply.

[0054] Multiple casters 6 are fixedly connected to the other side of the outer casing 1, and a pull rod 601 is slidably connected to the side of the outer casing 1 away from the casters 6.

[0055] A rocker arm 7 is provided on the surface of the outer casing 1 near the pull rod 601. The rocker arm 7 passes through the outer casing 1 and is rotatably connected to the power generation component. The power generation component is located on the inner surface of the battery 701.

[0056] Multiple outward-facing wheels fixedly connected to the other side of the housing 1 are used to control the movement of the housing 1. When moving, the housing 1 can be pulled to move the device. A rocker arm 7 is provided on the side of the housing 1 near the pull rod 601 to operate the power generation component by hand, thereby realizing the power generation of the device.

[0057] A solar panel 8 is attached to the outer surface of the battery 701. The solar panel 8 is folded and installed on the outer surface of the battery 701.

[0058] The solar panel 8, which is attached to the outer surface of the battery 701, is used to absorb solar energy to generate electricity. The solar panel 8 is folded and installed on the outer surface of the battery 701 so that it can be quickly removed and generated electricity through solar energy.

[0059] Both the filter tank 105 and the reverse osmosis tank 106 contract from the end near the connecting block 104 to the other end, and the contracted end is connected to the outlet.

[0060] The filter tank 105 and the reverse osmosis tank 106 contract from the connecting block 104 to the other end to discharge sewage. The diameter of the contracted end is small, which results in a faster water discharge speed and accelerates the discharge of purified water.

[0061] The output of pretreatment filter 1 is connected to pretreatment filter 2 401, the output of pretreatment filter 2 401 is connected to post-filter 402, the output of post-filter 402 is connected to self-cleaning filter 403, and the output of self-cleaning filter 403 is connected to reverse osmosis filter 1 101 and reverse osmosis filter 2 102 respectively.

[0062] During filtration, wastewater undergoes primary pretreatment through pretreatment filter 4. The treated wastewater then enters pretreatment filter 401 for secondary treatment. After that, the wastewater enters post-filter 402 and self-cleaning filter 403 for filtration, removing most of the impurities inside the wastewater. Finally, it enters reverse osmosis filter 101 and reverse osmosis filter 102 for osmosis filtration to achieve wastewater purification.

[0063] The usage process of the filter self-cleaning structure of a portable water purifier based on dual self-powered power supply provided by this invention is as follows:

[0064] When cleaning the reverse osmosis plate 111 and the reverse osmosis plate, the geared motor 202 can be turned on. After the geared motor 202 is turned on, it drives the electric telescopic rod 201 to rotate, which in turn drives the reverse osmosis plate 111 to rotate. During the rotation of the reverse osmosis plate 111, the solid plate 115 part of the reverse osmosis plate 114 and the filter plate 116 part of the reverse osmosis plate 114 are in contact, thereby achieving a seal between the reverse osmosis plate 111 and the reverse osmosis plate 114. Then the electric telescopic rod 201 retracts, which drives the spring 110 and the slider 109 to slide. During the sliding process, the slider 109 drives the gas inside the slide groove 108 to push, and the pushed gas cleans the flexible filter plate 116.
