Description

Technical Field

[0001] This invention relates to the field of water purifier technology, and in particular to a filter cartridge fixing system and method for a flip-top water purifier. Background Technology

[0002] Besides wall-mounted water purifiers, there are also countertop water purifiers on the market. These are designed for direct use by connecting the water source to the inlet, eliminating the need for drilling and making them more convenient. However, to maintain an aesthetically pleasing appearance, these countertop purifiers have a removable outer casing around the filter. During daily use, the casing covers the filter. To replace the filter, the casing is removed, and then the multiple filters are rotated sequentially to remove and replace the filter cartridge. This process requires opening the casing and repeating the rotation process. The process of removing multiple filters is cumbersome and increases labor costs. Even some water purifiers with optimized filter structures, which do not require rotating the filters and use snap-fit ​​connections, still require repeated operations to remove and install multiple filters. It is not possible to remove multiple filters simultaneously while opening the outer casing. In addition, after the filters are removed, a large amount of water remains inside. Since existing water purifiers do not have corresponding water removal structures, a large amount of water can easily spill onto the ground during the removal of filter cartridges, causing the ground to become dirty and requiring manual cleaning, which increases the labor intensity of filter cartridge replacement.

[0003] Therefore, it is necessary to provide a new flip-top water purifier filter cartridge fixing system and fixing method to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0061] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0062] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0063] Please see Figures 1 to 20This invention provides a flip-top water purifier filter cartridge fixing system, comprising a housing 1, connectors 2, connecting rods 3, sleeves 4, cover plates 5, and a synchronous fixing device 7. The housing 1 has an upper inner cavity 1a at its upper end and a lower inner cavity 1b at its lower end. Connectors 2 are equidistantly fixed to the side wall of the housing 1 between the upper inner cavity 1a and the lower inner cavity 1b. Connectors 2 have inlets 2a and outlets 2b, respectively. The inlets 2a and outlets 2b of two adjacent connectors 2 are connected via pipes 2c. An inlet pipe 2d is connected to the inlet 2a of one connector 2 on one side of the housing 1, and an outlet pipe 2e is connected to the outlet 2b of one connector 2 on the side of the housing 1 away from the inlet pipe 2d. The ends of both the inlet pipe 2d and the outlet pipe 2e are... The inlet 2a extends through the outer shell 1 to the outside of the outer shell 1. The lower end of the inlet 2a is inserted into the inner wall of the filter element 4a. The connecting rod 3 is located inside the lower inner cavity 1b, and support seats 3a are fixed at equal intervals on the outer wall of the connecting rod 3. The sleeve 4 is fixed on the inner wall of the support seat 3a, and the filter element 4a is inserted into the inner side of the sleeve 4. The bottom of the sleeve 4 has a drain outlet 4b, and the lower end of the drain outlet 4b extends through the support seat 3a to the bottom surface of the support seat 3a. The inlet pipe 2d on one end of the connector 2 is connected to the water source. The water source enters the inner side of the filter element 4a below the connector 2 at the end, and then enters the inner side of the sleeve 4 after being filtered by the filter element 4a. Then, it enters the adjacent connecting tube 2c through the outlet 2b on the connector 2 above the sleeve 4. The water flows through the inlet 2a of connector 2, where it passes through three filter elements 4a in sequence for filtration. Finally, the water flows out through the outlet pipe 2e on a connector 2 at the other end. The cover plate 5 is rotatably installed on the inner wall of the lower inner cavity 1b. The lower end of the cover plate 5 is snapped into the lower inner cavity 1b by a snap-fit ​​device 6. A rotating rod 11 is fixed to the upper end of the cover plate 5. Both ends of the rotating rod 11 are rotatably connected to the inner wall of the lower inner cavity 1b through bearings. The synchronous fixing device 7 consists of a synchronous rotating assembly 8 fixed to both ends of the connecting rod 3 and a synchronous lifting assembly 9 rotatably connected to both ends of the connecting rod 3 through bearings. It is used to synchronously drive the sleeve 4 to descend and flip when the cover plate 5 is opened. The water storage tank 14 is fixed to the bottom of the outer shell 1, and a drain pipe 14a is fixed to the lower end of the outer wall of the water storage tank 14. A first valve 14a1 is installed on the water pipe 14a. An exhaust chamber 14b is provided at the upper end of the outer wall of the water storage tank 14. A drainage device 15 is fixed to the bottom of the support base 3a, and its other end is connected to the water storage tank 14. It is used to drain water from the inside of the sleeve 4 when the sleeve 4 is disassembled. The drainage device 15 includes: a second valve 151 fixed to the bottom of the support base 3a; the second valve 151 consists of a valve body 151a and a valve handle 151b; the inlet end of the second valve 151 is connected to the drain outlet 4b; a connecting hose 152 is fixed to the outlet end of the second valve 151; the bottom of the connecting hose 152 penetrates the outer shell 1 and is connected to the water storage tank 14; and a valve opening bar 153 is fixed to the inner wall of the lower inner cavity 1b.The valve-closing bar 154 is fixed to the inner wall of the lower inner cavity 1b and is located directly above the valve-opening bar 153.

[0064] This application eliminates the need for sequential opening of the cover plate 5 and disassembly of multiple sleeves 4 during use. Simply opening the cover plate 5 allows for simultaneous disassembly of multiple sleeves 4, and similarly, closing the cover plate 5 allows for simultaneous installation of multiple sleeves 4. This effectively reduces the number of steps required to disassemble the filter element 4a, saves manpower, and facilitates operation. Furthermore, the drainage structure of the sleeves 4 allows for the drainage of water inside the sleeves 4 during disassembly, preventing a large amount of water from spilling onto the ground during filter element 4a disassembly.

[0065] Sealing gaskets 10 are fixed on the middle and edge of the bottom of connector 2. The top of sleeve 4 and the top of filter element 4a are pressed against the bottom of a corresponding sealing gasket 10 to reduce the probability of leakage.

[0066] The inner wall of the support 3a is chamfered, which facilitates the insertion of the sleeve 4 into the inner side of the support 3a.

[0067] The synchronous rotation assembly 8 includes a flip plate 81, a first follower column 82, and a bending frame 83. The flip plate 81 is symmetrically fixed at both ends of the connecting rod 3. The first follower column 82 is rotatably connected to the end of the flip plate 81 away from the connecting rod 3 through a bearing. The bending frame 83 is symmetrically fixed on the inner wall of the lower end of the lower inner cavity 1b, and the first follower column 82 is inserted into the inner wall of the bending frame 83.

[0068] The synchronous lifting assembly 9 includes a lifting plate 91, a drive frame 92, a rotating shaft 93, a drive plate 94, a second follower column 95, a first synchronous pulley 96, a second synchronous pulley 97, and a third synchronous belt 98. The lifting plate 91 is symmetrically slidably connected to the inner walls on both sides of the lower inner cavity 1b, and the lower end of the lifting plate 91 is rotatably connected to the end of the connecting rod 3 through a bearing. The drive frame 92 is fixed to the upper end of the lifting plate 91. The rotating shaft 93 is symmetrically rotatably connected to the inner wall at the upper end of the lower inner cavity 1b through a bearing. The drive plate 94 is fixed to the end of the rotating shaft 93. The end of the drive plate 94 away from the rotating shaft 93 is rotatably connected to the second follower column 95 through a bearing. The end of the second follower column 95 is rotatably connected to the inner wall of the drive frame 92. The first synchronous pulley 96 is fixed to the end of the rotating shaft 93. The second synchronous pulley 97 is symmetrically fixed to both ends of the rotating rod 11, and the first synchronous pulley 96 and the second synchronous pulley 97 are connected by the third synchronous belt 98.

[0069] When filter element 4a needs to be replaced, first cut off the water supply to prevent water from flowing into the entire device. Unlock the latching device 6 to release the lock between the lower end of the cover plate 5 and the lower inner cavity 1b. Then, flip the cover plate 5 upwards, causing the rotating rod 11 to rotate, which in turn causes the second synchronous pulley 97 to rotate. The third synchronous belt 98 then drives the first synchronous pulley 96 to rotate, which in turn drives the rotating shaft 93 to rotate. This, in turn, drives the drive plate 94 to rotate, which in turn drives the drive frame 92 to move downwards via the second follower column 95. This causes the lifting plate 91 to slide downwards, which in turn causes the connecting rod 3 to move downwards, thus separating the sleeve 4 from the connector 2. After the disassembly of sleeve 4 and connector 2 is completed, as connecting rod 3 continues to descend, when the first follower column 82 reaches the lower end of bending frame 83, it is guided by bending frame 83, causing the first follower column 82 to rotate around the axis of connecting rod 3. This drives the flip plate 81 to rotate, which in turn drives the connecting rod 3 to rotate. Consequently, sleeve 4 rotates to the outer side of the lower inner cavity 1b. Finally, after cover plate 5 is fully opened, sleeve 4 is in an inclined state. Due to the weight of connecting rod 3, support seat 3a, and sleeve 4, lifting plate 91 is protected at the lower end, thus keeping cover plate 5 open.

[0070] Furthermore, during the initial opening of the cover plate 5, as the connecting rod 3 moves downward, it is actuated by the valve opening bar 153, causing the valve handle 151b of the second valve 151 to rotate, thereby opening the second valve 151. Water inside the sleeve 4 then enters the connecting hose 152 through the drain port 4b and the second valve 151, and then flows into the water tank 14, thus emptying the water inside the sleeve 4. This prevents a large amount of water from spilling onto the ground when the filter element 4a is removed, ensuring a clean environment during filter element 4a replacement. After replacing the filter element 4a, the first valve 14a1 can be opened to drain the water inside the water tank 14 into a receiving container for disposal.

[0071] Then, the filter elements 4a inside the three sleeves 4 can be removed one by one and replaced with new filter elements 4a. After replacement, the cover plate 5 is closed by rotating it. When the cover plate 5 is rotated to reset, it drives the rotating shaft 93 to rotate, thereby causing the drive plate 94 to flip upward. This drives the drive frame 92 to move upward through the second follower column 95, thereby pulling the lifting plate 91 upward. Through the action of the bending frame 83 and the first follower column 82, the connecting rod 3 rotates to reset. Then, the sleeve 4 returns to the center. As the cover plate 5 continues to close and rotate, the sleeve 4 and filter element 4a move upward and press against the bottom of the connector 2. Finally, the locking device 6 positions the cover plate 5 closed, and the sleeve 4 and filter element 4a remain pressed against the bottom of the sealing gasket 10, completing the fixing of the filter element 4a.

[0072] Furthermore, at the end of the closing of the cover plate 5, when the connecting rod 3 finishes rotating and moves vertically upward, the valve handle 151b is finally blocked by the valve closing bar 154, which causes the valve handle 151b to rotate. Finally, after the connecting rod 3 is reset, the valve handle 151b rotates to close the second valve 151. It should be emphasized that the latching device 6 is existing technology and will not be described again.

[0073] A connecting sleeve 12 is symmetrically fixed on the inner wall of the lower inner cavity 1b. The lifting plate 91 is slidably connected to the inner wall of the connecting sleeve 12, so that the lifting plate 91 can slide smoothly up and down.

[0074] A handle 13 is fixed on the outer wall of the cover plate 5, which makes it easy for people to turn and open the cover plate 5.

[0075] The present invention also provides a method for fixing the filter element of a flip-top water purifier, wherein the filter element 4a is fixed using the above-mentioned flip-top water purifier filter element fixing system.

[0076] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
