Description

Technical Field

[0001] This invention belongs to the field of water purifier technology, specifically a water purifier with a quick-opening structure. Background Technology

[0002] Currently, the connection between the end cap and the cylinder of ultrafiltration water purifiers generally uses either screw flange connection or clamp connection, which are the mainstream technical solutions on the market. However, these connection methods have obvious drawbacks. The disassembly and assembly process requires special tools, is cumbersome, and requires a certain level of physical strength from the user. Users with less strength, such as women, often find it difficult to complete the disassembly and assembly independently. At the same time, screw flange connections require tightening multiple screws, and clamp connections also require considerable effort to tighten or loosen, resulting in a long overall disassembly and assembly time, causing inconvenience for users' daily maintenance such as filter replacement.

[0003] With the increasing popularity of water purifiers, users' demand for convenient equipment maintenance is growing. The time-consuming and labor-intensive problems of traditional connection structures are becoming more and more prominent, and they can no longer meet users' needs for efficient and easy equipment maintenance. There is an urgent need for a tool-free, labor-saving and quick end cap and cylinder connection structure to solve the above problems.

[0004] In the current technology, the connection between the end cap and the cylinder of a common ultrafiltration water purifier is either through screw flanges or through clamps. Tools are needed for installation, and it is laborious to disassemble and assemble. Women with less strength may not be able to complete the task. In particular, the screw flange connection has more screws and takes more time, which is not conducive to the subsequent replacement of the inlet filter cartridge. Summary of the Invention

[0005] The purpose of this invention is to provide a water purifier with a quick-opening structure in order to solve the problem of providing a water purifier with a quick-opening structure mentioned above.

[0006] The technical solution adopted in this invention is as follows: A water purifier with a quick-opening structure includes a cylinder, an mounting ring plate fixedly connected to the upper end of the cylinder, an end cap provided at the upper end of the mounting ring plate, and multiple lower claw pieces provided on the sides of the end cap and the sealing cap. The size of the lower claw pieces and the sealing cap are adapted to the size of the end cap. The other end of the lower claw piece is engaged with the lower end of the mounting ring plate. An upper claw piece is fixedly connected to the upper end of the lower claw piece, and a sliding column is fixedly connected to the upper end of the upper claw piece. Multiple lower claw pieces and upper claw pieces are evenly arranged at the upper end of the end cap.

[0007] The upper end of the end cap is rotatably connected to a large gear located in the middle of adjacent upper claw plates. The large gear has an internal guide groove, and the sliding column is located in the guide groove. A small gear is meshed with the side of the large gear, and a connecting rod is fixedly connected to the upper end of the small gear.

[0008] The upper end of the upper claw plate is provided with a pressure cap, the upper end of the pressure cap is snapped into a round cover plate, the upper end of the round cover plate is provided with a round handle, and the other end of the connecting rod passes through the pressure cap and the round cover plate and is fixedly connected to the round handle.

[0009] By adopting the above technical solution, the lower claw plate is used in conjunction with the upper claw plate to limit the position of the end cap on the upper end of the mounting ring plate, thereby fixing the end cap to the upper end of the cylinder, ensuring stable connection between structures, and facilitating subsequent operation.

[0010] The rotating handle drives the connecting rod, which in turn connects to a small gear, which in turn drives the large gear. When the large gear rotates, it causes the sliding post to move within the guide groove. This movement of the sliding post allows the upper claw plate to move radially, facilitating the installation and removal of the end cover. Rotating the handle clockwise moves the upper claw plate radially outward, unfolding the lower claw plate and its structure. The operator then places the end cover on top of the mounting ring plate and rotates the handle counterclockwise, moving the upper claw plate radially inward, causing the lower claw plate to engage with the side of the end cover and the mounting ring plate. The mechanism enables the locking and unlocking of the end cover and the mounting ring plate. A large and small gear allow the operator to easily open or close the structure by manually rotating a round handle. The lower claw plate engages with the side of the end cover and the mounting ring plate, securing the end cover in place and ensuring stability. This design facilitates quick and easy disassembly and installation of the end cover. The gear mechanism reduces the effort required for opening, making it easier for operators to control. This new quick-opening structure allows for easy and convenient opening of the end cover when changing filter cartridges, improving work efficiency.

[0011] In a preferred embodiment, an outer ring plate is provided at the upper end of the circular cover plate adjacent to the circular handle. A pressing post is slidably connected inside the outer ring plate. A lower connecting post is fixedly connected to the lower end of the pressing post. A working spring is provided at the lower end of the lower connecting post. A pressure cap is fixedly connected to the lower end of the working spring.

[0012] A side limiting plate is fixedly connected to the side of the round handle, and an inner connecting rod is fixedly connected to the side of the pressing column. A limiting post is fixedly connected to the other end of the inner connecting rod, and the other end of the limiting post passes through the round cover plate and is engaged in the slot provided in the side limiting plate.

[0013] The circular cover plate has multiple mounting holes inside, and the working dimensions of the mounting holes are adapted to the dimensions of the pressing column, connecting rod and limiting column, respectively. The working spring is made of a material that meets the standards.

[0014] By adopting the above technical solution, the setting of limiting posts and side limiting plates facilitates the installation of a child lock structure in the structure during operation, thereby preventing children from turning the round handle, increasing the connection stability of the structure, and benefiting subsequent operation.

[0015] The outer ring plate is positioned to support the pressing column. Pressing the pressing column compresses the working spring at the lower end of the connecting column, causing the pressing column to slide within the outer ring plate. An inner connecting rod then moves the position of the limiting column, displacing it downwards and allowing it to move out of the side limiting plate. This facilitates subsequent rotation of the round handle. During installation, when not under pressure, the working spring supports the pressing column, keeping it in its initial position. The inner connecting rod connects to the limiting column, causing it to engage in a slot within the side limiting plate. The structural working position is designed to meet expectations. Pressing the pressing column moves the limiting column, releasing its restriction on the round handle and allowing for easy rotation. A working spring made of standard materials facilitates the resetting of the pressing column, allowing for multiple adjustments and extending the structure for extended use.

[0016] In a preferred embodiment, the upper claw plate has a plurality of auxiliary grooves located adjacent to the sliding column, and the pressure cap has a plurality of internal through holes.

[0017] By adopting the above technical solution, the auxiliary groove is used in conjunction with the mounting screw. When fixing the pressure cap, it does not delay the movement of the upper claw plate, which facilitates the subsequent adjustment of the working position of the upper claw plate.

[0018] In a preferred embodiment, the upper end of the end cap is fixedly connected to a plurality of mounting screws inside the auxiliary groove. The working dimension of the auxiliary groove is larger than that of the mounting screws. The other end of the mounting screws is threaded through an inner through hole and connected to a nut.

[0019] By adopting the above technical solution, the mounting screw is designed to facilitate the installation of the pressure cap. The auxiliary groove passes through the inner through hole of the pressure cap and is threaded to connect the nut, so that the pressure cap is fixedly installed on the upper end of the end cap, which facilitates subsequent operations.

[0020] In a preferred embodiment, a base is fixedly connected to the lower end of the cylinder.

[0021] By adopting the above technical solution, the working position of the base supports the cylinder, ensuring the stability of the structure and facilitating subsequent operation.

[0022] In a preferred embodiment, an isolation plate is fixedly connected inside the cylinder, and a filter element assembly is disposed inside the cylinder at a position adjacent to the isolation plate.

[0023] By adopting the above technical solution, the isolation plate is designed to isolate the space inside the cylinder and work in conjunction with the filter cartridge assembly, so that the filtered water and the unfiltered water are separated, making it easier to collect the filtered water for subsequent use.

[0024] In a preferred embodiment, the filter element assembly is provided with a PVDF ultrafiltration membrane.

[0025] By adopting the above technical solutions, tiny impurities and other harmful substances in the water are removed through physical filtration, providing cleaner and safer drinking water. As a high-performance filter medium, PVDF ultrafiltration membrane 26 has very high mechanical strength and chemical stability, and can effectively filter large molecules such as particulate matter, suspended solids, and silt in the water, but does not filter small molecules such as dissolved salts and minerals in the water, thus preserving the natural mineral content of the water.

[0026] In a preferred embodiment, a metal filter screen is fixedly connected to the lower end of the filter element assembly, and a water inlet is provided on the side of the cylinder. The other end of the water inlet is connected to the lower end of the metal filter screen inside the cylinder.

[0027] By adopting the above technical solution, the water inlet transports the water to be purified to the lower end of the filter element assembly. The filter element assembly and its internal filtration layer filter the water. The metal filter screen removes large particles of impurities, reduces the burden on subsequent filtration layers, and facilitates long-term operation.

[0028] In a preferred embodiment, a water outlet is fixedly connected to the side of the cylinder opposite to the water inlet, and the other end of the water outlet is connected to the cylinder at a position adjacent to the isolation plate.

[0029] By adopting the above technical solution, the outlet is designed to facilitate the discharge of purified water from the equipment. By connecting the outlet to other structures, the purified water can be transported to other work areas, ensuring the normal operation of the equipment.

[0030] In a preferred embodiment, a drain outlet is provided on the side of the cylinder adjacent to the water inlet, and the other end of the drain outlet is located inside the cylinder adjacent to the water inlet. A sealing cap is provided on the side of the drain outlet.

[0031] By adopting the above technical solution, the other end of the sewage outlet is connected to the inside of the cylinder, which is used in conjunction with the equipment for sewage discharge operations. This facilitates the subsequent cleaning of impurities generated during the filtration operation inside the cylinder. The sealing cover ensures the sealing of the sewage outlet and ensures the stability of the structural connection.

[0032] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0033] In this invention, the lower claw plate is used in conjunction with the upper claw plate to restrict the position of the end cap on the upper end of the mounting ring plate, thereby fixing the end cap to the upper end of the cylinder, ensuring stable connection between the structures, and facilitating subsequent operation.

[0034] The rotating handle drives the connecting rod, which in turn connects to a small gear, which in turn drives the large gear. When the large gear rotates, it causes the sliding post to move within the guide groove. This movement of the sliding post allows the upper claw plate to move radially, facilitating the installation and removal of the end cover. Rotating the handle clockwise moves the upper claw plate radially outward, unfolding the lower claw plate and its structure. The operator then places the end cover on top of the mounting ring plate and rotates the handle counterclockwise, moving the upper claw plate radially inward, causing the lower claw plate to engage with the side of the end cover and the mounting ring plate. The mechanism enables the locking and unlocking of the end cover and the mounting ring plate. Through the large and small gears, the operator can easily open or close the structure by manually rotating the round handle. The lower claw plate easily engages with the side of the end cover and the mounting ring plate, thus fixing the end cover in place on the upper part of the mounting ring plate and ensuring its stability. This design facilitates quick disassembly and installation of the end cover. The gear mechanism reduces the force required for opening, making it easier for operators to control. With this new quick-opening structure, the end cover can be easily and conveniently opened when changing the filter element, improving work efficiency.

[0035] The setting of limiting posts and side limiting plates facilitates the installation of child locks during operation, thereby preventing children from turning the round handle, increasing the stability of the structure's connection, and benefiting subsequent operation.

[0036] The outer ring plate is positioned to support the pressing column. Pressing the pressing column compresses the working spring at the lower end of the connecting column, causing the pressing column to slide within the outer ring plate. An inner connecting rod then moves the position of the limiting column, displacing it downwards and allowing it to move out of the side limiting plate. This facilitates subsequent rotation of the round handle. During installation, when not under pressure, the working spring supports the pressing column, keeping it in its initial position. The inner connecting rod connects to the limiting column, causing it to engage in a slot within the side limiting plate. The structural working position is designed to meet expectations. Pressing the pressing column moves the limiting column, releasing its restriction on the round handle and allowing for easy rotation. A working spring made of standard materials facilitates the resetting of the pressing column, allowing for multiple adjustments and extending the structure for extended use.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example:

[0048] Reference Figure 1-3 , Figure 6 , Figure 8 A water purifier with a quick-opening structure includes a cylinder 1. An mounting ring plate 24 is fixedly connected to the upper end of the cylinder 1. An end cap 20 is provided at the upper end of the mounting ring plate 24. Multiple lower claw pieces 5 are provided on the sides of the end cap 20 and the sealing cap 14. The size of the lower claw pieces 5 and the sealing cap 14 are adapted to the size of the end cap 20. The other end of the lower claw pieces 5 is snapped into the lower end of the mounting ring plate 24. An upper claw piece 6 is fixedly connected to the upper end of the lower claw pieces 5. A sliding column 15 is fixedly connected to the upper end of the upper claw piece 6. Multiple lower claw pieces 5 and upper claw pieces 6 are evenly arranged at the upper end of the end cap 20.

[0049] The upper end of the end cap 20 is rotatably connected to a large gear 16 located in the middle of the adjacent upper claw plates 6. The large gear 16 has an internal guide groove 19, and the sliding column 15 is located in the guide groove 19. The side of the large gear 16 is meshed with a small gear 18, and the upper end of the small gear 18 is fixedly connected to a connecting rod 17.

[0050] The upper end of the upper claw plate 6 is provided with a pressure cap 12, the upper end of the pressure cap 12 is snapped into the round cover plate 9, the upper end of the round cover plate 9 is provided with a round handle 11, the other end of the connecting rod 17 passes through the pressure cap 12 and the round cover plate 9 and is fixedly connected to the round handle 11. The lower claw plate 5 is used in conjunction with the upper claw plate 6 to restrict the position of the end cap 20 at the upper end of the mounting ring plate 24, so that the end cap 20 is fixed at the upper end of the cylinder 1, ensuring the stable connection between the structures and facilitating subsequent operation.

[0051] The circular handle 11 drives the connecting rod 17 to rotate, which in turn drives the pinion 18 to rotate. The pinion 18 then drives the large gear 16 to rotate. When the large gear 16 rotates, it moves the sliding column 15 within the guide groove 19. This movement of the sliding column 15 allows the upper claw plate 6 to move radially, facilitating the installation and removal of the end cover 20. Rotating the circular handle 11 clockwise moves the upper claw plate 6 radially outward, unfolding the structure of the lower claw plate 5 and the upper claw plate 6. The operator then places the end cover 20 on the upper end of the mounting ring plate 24 and rotates the circular handle 11 counterclockwise, moving the upper claw plate 6 radially inward, causing the lower claw plate 5 to engage with the end cover 20 and the mounting ring plate 24. The side of plate 24 allows for locking and unlocking of the connection between end cover 20 and mounting ring plate 24. With the large gear 16 and small gear 18, operators can easily open or close the structure by manually rotating the round handle 11. The lower claw plate 5 is designed to easily engage with the side of end cover 20 and mounting ring plate 24, thus fixing the end cover 20 in position on the upper end of mounting ring plate 24 and ensuring its stability. This structure facilitates quick disassembly and installation of end cover 20. The gear mechanism reduces the force required for opening, making it easier for operators to control. This new quick-opening structure allows for easy and convenient opening of the end cover when changing filter elements, improving work efficiency.

[0052] Reference Figure 1-3 , Figure 5 An outer ring plate 7 is provided at the upper end of the round cover plate 9 adjacent to the round handle 11. A pressing post 8 is slidably connected inside the outer ring plate 7. A lower connecting post 31 is fixedly connected to the lower end of the pressing post 8. A working spring 32 is provided at the lower end of the lower connecting post 31. The lower end of the working spring 32 is fixedly connected to the pressure cover 12.

[0053] A side limiting plate 10 is fixedly connected to the side of the round handle 11, and an inner connecting rod 33 is fixedly connected to the side of the pressing column 8. The other end of the inner connecting rod 33 is fixedly connected to a limiting column 28, and the other end of the limiting column 28 passes through the round cover plate 9 and is engaged in the slot provided in the side limiting plate 10.

[0054] The round cover plate 9 has multiple mounting holes inside. The working size of the mounting holes is adapted to the size of the pressing post 8, the connecting rod 17 and the limiting post 28 respectively. The working spring 32 is made of standard materials. The limiting post 28 and the side limiting plate 10 facilitate the setting of a child lock structure in operation, thereby preventing children from turning the round handle 11, increasing the connection stability of the structure and facilitating subsequent operation.

[0055] By positioning the pressing post 8 on the outer ring plate 7, pressing the pressing post 8 compresses the working spring 32 at the lower end of the connecting post 31, causing the pressing post 8 to slide within the outer ring plate 7. This, in turn, causes the limiting post 28 to move downwards via the inner connecting rod 33, allowing it to move out of the side limiting plate 10. This facilitates the subsequent rotation of the round handle 11. During structural installation, when not under pressure, the working spring 32 supports the position of the pressing post 8, ensuring its proper functioning. In the initial position, the inner connecting rod 33 connects to the limiting post 28, so that the limiting post 28 is engaged in the slot in the side limiting plate 10. The working position setting of the structure meets the expected use. Subsequently, by pressing the pressing post 8, the position of the limiting post 28 is moved, thereby releasing the restriction of the limiting post 28 on the round handle 11, so that the operator can turn the round handle 11 for use. The working spring 32, which is made of standard materials, can easily drive the pressing post 8 to reset, so that the structure can be extended and retracted multiple times, which is beneficial for long-term operation.

[0056] Reference Figure 1-3 , Figure 6 The upper claw plate 6 has multiple auxiliary grooves 21 located adjacent to the sliding column 15. The pressure plate 12 has multiple internal through holes 29. The auxiliary grooves 21 are used in conjunction with the mounting screws 22. When fixing the pressure plate 12, the position movement of the upper claw plate 6 is not delayed, which facilitates the subsequent adjustment of the working position of the upper claw plate 6.

[0057] Reference Figure 1-3 , Figure 6-7 The upper end of the end cap 20 is located inside the auxiliary groove 21 and is fixedly connected to multiple mounting screws 22. The working size of the auxiliary groove 21 is larger than that of the mounting screws 22. The other end of the mounting screw 22 passes through the inner through hole 29 and is threaded with a nut 23. The mounting screw 22 is designed to facilitate the installation of the pressure cap 12. The pressure cap 12 is fixedly installed on the upper end of the end cap 20 by passing through the inner through hole 29 in the auxiliary groove 21 and threading with the nut 23, which facilitates subsequent operations.

[0058] Reference Figure 1-3 The lower end of the cylinder 1 is fixedly connected to the base 3, which supports the working position of the cylinder 1, ensuring the stability of the structure and facilitating subsequent operation.

[0059] Reference Figure 1-3 An isolation plate 30 is fixedly connected inside the cylinder 1. A filter element assembly 25 is arranged inside the cylinder 1 at a position adjacent to the isolation plate 30. The isolation plate 30 is arranged to isolate the space inside the cylinder 1. When used in conjunction with the filter element assembly 25, it separates the filtered water from the unfiltered water, making it easier to collect the filtered water for subsequent use.

[0060] Reference Figure 1-4 The filter element assembly 25 is equipped with a PVDF ultrafiltration membrane 26, which removes tiny impurities and other harmful substances from the water through physical filtration, providing cleaner and safer drinking water. As a high-performance filter medium, the PVDF ultrafiltration membrane 26 has very high mechanical strength and chemical stability, and can effectively filter large molecules such as particulate matter, suspended solids, and silt in the water, but does not filter small molecules such as dissolved salts and minerals in the water, thus retaining the natural mineral content of the water.

[0061] Reference Figure 1-4 A metal filter screen 27 is fixedly connected to the lower end of the filter element assembly 25. A water inlet 2 is provided on the side of the cylinder 1. The other end of the water inlet 2 is connected to the lower end of the metal filter screen 27 inside the cylinder 1. The water inlet 2 transports the water to be purified to the lower end of the filter element assembly 25. The water to be purified is filtered through the filter element assembly 25 and its internal filter layer. The metal filter screen 27 removes large particles of impurities, reduces the burden on the subsequent filter layer, and facilitates long-term operation.

[0062] Reference Figure 1-4 The side of the cylinder 1 is fixedly connected to the outlet 13 on the opposite side of the inlet 2. The other end of the outlet 13 is connected to the cylinder 1 at the position adjacent to the isolation plate 30. The outlet 13 is set to facilitate the discharge of purified water from the equipment. Through the outlet 13, other structures are connected to transport the purified water to other work areas to ensure the normal operation of the equipment.

[0063] Reference Figure 1-4 A drain port 4 is provided on the side of the cylinder 1, adjacent to the water inlet 2. The other end of the drain port 4 is located inside the cylinder 1, adjacent to the water inlet 2. A sealing cover 14 is provided on the side of the drain port 4. The other end of the drain port 4 is connected to the inside of the cylinder 1. It is used in conjunction with the equipment for sewage discharge operations, which facilitates the subsequent cleaning of impurities generated during the filtration operation inside the cylinder 1. The sealing cover 14 ensures the sealing of the drain port 4 and ensures the stability of the structural connection.

[0064] The implementation principle of the water purifier embodiment with a quick-opening structure of the present invention is as follows:

[0065] The lower claw plate 5 works in conjunction with the upper claw plate 6 to restrict the position of the end cap 20 on the upper end of the mounting ring plate 24, thereby fixing the end cap 20 to the upper end of the cylinder 1, ensuring stable connection between structures, and facilitating subsequent operations.

[0066] The circular handle 11 drives the connecting rod 17 to rotate, which in turn drives the pinion 18 to rotate. The pinion 18 then drives the large gear 16 to rotate. When the large gear 16 rotates, it moves the sliding column 15 within the guide groove 19. This movement of the sliding column 15 allows the upper claw plate 6 to move radially, facilitating the installation and removal of the end cover 20. Rotating the circular handle 11 clockwise moves the upper claw plate 6 radially outward, unfolding the structure of the lower claw plate 5 and the upper claw plate 6. The operator then places the end cover 20 on the upper end of the mounting ring plate 24 and rotates the circular handle 11 counterclockwise, moving the upper claw plate 6 radially inward, causing the lower claw plate 5 to engage with the end cover 20 and the mounting ring plate 24. The side of plate 24 allows for locking and unlocking of the connection between end cover 20 and mounting ring plate 24. With the large gear 16 and small gear 18, operators can easily open or close the structure by manually rotating the round handle 11. The lower claw plate 5 is designed to easily engage with the side of end cover 20 and mounting ring plate 24, thus fixing the end cover 20 in position on the upper end of mounting ring plate 24 and ensuring its stability. This structure facilitates quick disassembly and installation of end cover 20. The gear mechanism reduces the force required for opening, making it easier for operators to control. This new quick-opening structure allows for easy and convenient opening of the end cover when changing filter elements, improving work efficiency.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
