Description

Technical Field

[0001] This utility model belongs to the field of filter technology, specifically a water dispenser filter that is easy to replace. Background Technology

[0002] Water dispenser filters are the core components of water dispensers, used to filter impurities and harmful substances in water, improve water quality, and ensure drinking water safety.

[0003] Filter cartridges effectively remove suspended solids, sediments, large particles, heavy metals, bacteria, viruses, and other harmful substances from water, effectively protecting drinking water safety. They also prevent the accumulation of impurities in the water from affecting other components, thus extending the lifespan of the water dispenser. However, after a certain period of use, impurities accumulate inside the filter cartridge, causing its filtration efficiency to deteriorate. In this case, the filter cartridge needs to be replaced promptly. Currently, replacing filter cartridges typically requires specialized disassembly and installation tools. Furthermore, if these tools are lost, the filter cartridge cannot be removed from the water dispenser, leading to inconvenience in the disassembly and installation process.

[0004] Therefore, this utility model provides a water dispenser filter element that is easy to replace. Utility Model Content

[0005] To overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a water dispenser filter element that is easy to replace is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The water dispenser filter element of this utility model that is easy to replace includes a cylinder cover, a guide rail fixedly connected to the side wall of the cylinder cover, a bidirectional lead screw rotatably connected inside the guide rail, a pair of sliders symmetrically threaded on the bidirectional lead screw, a clamp fixedly connected to the bottom of the slider, a cylinder body connected inside the cylinder cover, a pair of fixing rings fixedly connected to the side wall of the cylinder body, a reinforcing component and a connecting component provided on the side wall of the clamp, and a rotating component provided at the end of the bidirectional lead screw. Through the above structure, with the cooperation of the bidirectional lead screw, sliders and clamp, the connection and disassembly between the cylinder body and the cylinder cover can be completed by rotating the bidirectional lead screw, thereby improving the convenience of replacing the filter element inside the cylinder body and reducing the need for special tools to install and disassemble the cylinder body in the prior art, which leads to a more cumbersome and laborious process.

[0007] Preferably, the connecting component includes a fixing frame, which is fixedly connected to the side wall of the clamp, and an insert plate is fixedly connected to the other side wall of the clamp. The fixing frame and the insert plate are fixed by a fixing pin. With the above structure, the openings between the two clamps can be connected by the cooperation of the fixing frame, the insert plate and the fixing pin, thereby improving the tightness of the connection between the two clamps and thus improving the fixing effect on the cylinder.

[0008] Preferably, the top of the fixing ring is fixed with multiple upright plates, which are evenly distributed on the fixing ring. The bottom of the cylinder cover is provided with multiple insertion holes, and the upright plates are arranged corresponding to the insertion holes. Through the above structure, the upright plates can be inserted into the insertion holes to restrict the position of the cylinder body, reduce the occurrence of self-rotation of the cylinder body, and improve the stability of the cylinder body in the position of the cylinder cover.

[0009] Preferably, the reinforcing component includes a reinforcing strip disposed on the side wall of the clamp, and a plurality of uprights are provided on the reinforcing strip. The plurality of uprights are evenly distributed on the reinforcing strip. Through the above structure, the reinforcing strip and the uprights can improve the overall strength and rigidity of the clamp, so as to reduce the deformation and damage of the clamp during use.

[0010] Preferably, a retaining ring is fixedly connected to the top of the inner side of the cylinder cover, and a sealing ring is installed between the retaining ring and the inner side wall of the cylinder cover. Through the above structure, the retaining ring is inserted into the inside of the cylinder body and works with the sealing ring to seal the connection between the cylinder body and the cylinder cover, thereby improving the sealing performance of the connection between the cylinder body and the cylinder cover.

[0011] Preferably, the rotating assembly includes a turntable, which is fixed to the end of a bidirectional lead screw. The turntable has multiple anti-slip grooves on its sidewall. Through the above structure, the turntable can provide the operator with a position to apply force, and the anti-slip grooves can increase the friction when the operator holds the turntable, thereby improving the stability when rotating the turntable.

[0012] Preferably, the side wall of the cylinder cover is provided with multiple indicator marks, which are corresponding to the insertion holes. With the above structure, the one-to-one correspondence between the indicator marks and the insertion holes makes it easy for the operator to align the upright plate with the insertion holes, eliminating the need to observe the position of the insertion holes from the bottom of the cylinder cover, thus improving the convenience when installing the cylinder body.

[0013] The beneficial effects of this utility model are as follows: 1. The water dispenser filter element of this utility model is easy to replace. With the cooperation of a two-way screw, a slider and a clamp, the connection and disassembly between the cylinder body and the cylinder cover can be completed by rotating the two-way screw, thereby improving the convenience of replacing the filter element inside the cylinder body. This reduces the need for special tools to install and disassemble the cylinder body in the prior art, which makes the process more cumbersome and laborious.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] like Figures 1 to 4As shown in the embodiment of this utility model, a replaceable water dispenser filter element includes a cap 1. A guide rail 11 is fixedly connected to the side wall of the cap 1. A bidirectional lead screw 12 is rotatably connected inside the guide rail 11. A pair of sliders 13 are symmetrically threaded onto the bidirectional lead screw 12. A clamp 14 is fixedly connected to the bottom of each slider 13. A cylinder body 15 is connected inside the cap 1. A pair of fixing rings 16 are fixedly connected to the side wall of the cylinder body 15. The side wall of the clamp 14 is provided with a reinforcing component and a connecting component. A rotating component is provided at the end of the bidirectional lead screw 12. During operation, the cylinder body 15 is inserted from the bottom of the cap 1, and then the bidirectional lead screw 12 is rotated by the rotating component. At this time, the bidirectional lead screw 12 will drive the pair of sliders 13 to slide in opposite directions inside the guide rail 11. When the bidirectional lead screw 12 rotates clockwise, it will cause the pair of sliders 13 to slide in opposite directions. The two clamps 14 move closer together, causing them to fit onto the cylinder body 15. At this time, the clamps 14 are positioned between the two fixing rings 16. When the filter element needs to be replaced, the double-acting screw 12 is rotated counterclockwise to move a pair of sliders 13 away from each other. This releases the clamps 14 from the cylinder body 15, allowing the cylinder body 15 to be moved downwards and removed from the cylinder cover 1. The filter element inside the cylinder body 15 can then be replaced. Through the above structure, the double-acting screw 12, sliders 13, and clamps 14 work together to connect and disconnect the cylinder body 15 from the cylinder cover 1 by rotating the double-acting screw 12. This improves the convenience of replacing the filter element inside the cylinder body 15 and reduces the need for special tools to install and remove the cylinder body 15, which is cumbersome and laborious in the prior art.

[0021] like Figure 4 As shown, the connecting assembly includes a fixing frame 2, which is fixed to the side wall of the clamp 14. An insert plate 21 is fixed to the side wall of the clamp 14 on the other side. The fixing frame 2 and the insert plate 21 are fixed together by a fixing pin 22. During operation, after the clamp 14 is fixed to the cylinder body 15, the insert plate 21 is inserted into the fixing frame 2. Then, the fixing pin 22 is inserted into the holes on the fixing frame 2 and the insert plate 21 to connect them. When disassembling the cylinder body 15, the fixing pin 22 is removed first, and the connection between the fixing frame 2 and the insert plate 21 is released. Through the above structure, the fixing frame 2, the insert plate 21, and the fixing pin 22 work together to connect the openings between the two clamps 14, thereby improving the tightness of the connection between the two clamps 14 and thus improving the fixing effect on the cylinder body 15.

[0022] like Figure 2 and Figure 3As shown, multiple upright plates 3 are fixedly connected to the top of the fixing ring 16. The multiple upright plates 3 are evenly distributed on the fixing ring 16. Multiple insertion holes 31 are opened at the bottom of the cylinder cover 1. The upright plates 3 are correspondingly arranged with the insertion holes 31. During operation, when the cylinder body 15 is inserted into the cylinder cover 1, the upright plate 3 at the top of the upper fixing ring 16 is aligned with the insertion hole 31 at the bottom of the cylinder cover 1. After the cylinder body 15 is inserted into the cylinder cover 1, it will drive the upright plate 3 to be inserted into the insertion hole 31. Through the above structure, the insertion of the upright plate 3 into the insertion hole 31 can restrict the position of the cylinder body 15, reduce the situation of the cylinder body 15 rotating on its own, and improve the stability of the position of the cylinder body 15 in the cylinder cover 1.

[0023] like Figure 3 As shown, the reinforcing component includes a reinforcing strip 4, which is disposed on the side wall of the clamp 14. The reinforcing strip 4 is provided with multiple columns 41, which are evenly distributed on the reinforcing strip 4. During operation, when the clamp 14 deforms during use, the reinforcing strip 4 and the columns 41 are distributed horizontally and vertically on one side of the clamp 14 to support and reinforce the clamp 14. Through the above structure, the reinforcing strip 4 and the columns 41 can improve the overall strength and rigidity of the clamp 14, so as to reduce the deformation and damage of the clamp 14 during use.

[0024] like Figure 5 As shown, a retaining ring 5 is fixedly connected to the top of the inner side of the cylinder cover 1. A sealing ring 51 is installed between the retaining ring 5 and the inner wall of the cylinder cover 1. During operation, when the cylinder body 15 is inserted into the cylinder cover 1, the retaining ring 5 will contact the inner wall of the cylinder body 15. At this time, the top of the cylinder body 15 will just contact the retaining ring 5 between the retaining ring 5 and the cylinder cover 1. Through the above structure, the retaining ring 5 inserted inside the cylinder body 15, together with the sealing ring 51, seals the connection between the cylinder body 15 and the cylinder cover 1, thereby improving the sealing performance of the connection between the cylinder body 15 and the cylinder cover 1.

[0025] like Figure 4 As shown, the rotating assembly includes a turntable 6, which is fixed to the end of the bidirectional lead screw 12. The side wall of the turntable 6 is provided with multiple anti-slip grooves 61. During operation, the operator can hold the turntable 6 with their hand. When the turntable 6 is rotated, it will drive the bidirectional lead screw 12 to rotate simultaneously. Through the above structure, the turntable 6 can provide the operator with a position to apply force, and the anti-slip grooves 61 can increase the friction when the operator holds the turntable 6, thereby improving the stability when rotating the turntable 6.

[0026] like Figure 3 As shown, the side wall of the cylinder cover 1 is provided with multiple indicator marks 7, and the indicator marks 7 are correspondingly set with the insertion holes 31. Through the above structure, the one-to-one correspondence between the indicator marks 7 and the insertion holes 31 makes it easy for the operator to align the upright plate 3 with the insertion holes 31, so that it is no longer necessary to observe the position of the insertion holes 31 from the bottom of the cylinder cover 1, thus improving the convenience when installing the cylinder body 15.

[0027] Working principle: Insert the cylinder body 15 into the bottom of the cylinder cover 1, and then rotate the bidirectional screw 12 through the rotating assembly. At this time, the bidirectional screw 12 will drive a pair of sliders 13 to slide in opposite directions within the guide rail 11. When the bidirectional screw 12 rotates clockwise, the pair of sliders 13 will move closer together, thereby driving the two clamps 14 to be fitted onto the cylinder body 15. At this time, the clamps 14 are just located between the two fixing rings 16. When the filter element needs to be replaced, rotate the bidirectional screw 12 counterclockwise to drive the pair of sliders 13 away from each other. At this time, the clamps 14 will move away from each other, thus releasing the fixation on the cylinder body 15. Then, move the cylinder body 15 downwards to remove it from the cylinder cover 1. Then, replace the filter element inside the cylinder body 15. After the clamps 14 are fixed on the cylinder body 15, the insert plate 21 will be inserted into the fixing frame 2. Then, use the fixing pin 22 to insert the fixing plate 21 into the fixing frame 2. The fixed frame 2 and the insert plate 21 are connected by holes. When disassembling the cylinder body 15, the fixing pin 22 is removed first. At this time, the connection between the fixed frame 2 and the insert plate 21 will be released. When inserting the cylinder body 15 into the cylinder cover 1, the upright plate 3 at the top of the upper fixing ring 16 is aligned with the insertion hole 31 at the bottom of the cylinder cover 1. After the cylinder body 15 is inserted into the cylinder cover 1, the upright plate 3 will be inserted into the insertion hole 31. When the clamp 14 is deformed during use, the reinforcing strip 4 and the column 41 are distributed horizontally and vertically on one side of the clamp 14 to support and reinforce the clamp 14. When the cylinder body 15 is inserted into the cylinder cover 1, the retaining ring 5 will contact the inner wall of the cylinder body 15. At this time, the top of the cylinder body 15 will just contact the retaining ring 5 between the retaining ring 5 and the cylinder cover 1. The operator can hold the turntable 6 with his hand. When the turntable 6 is rotated, the bidirectional screw 12 will rotate at the same time.
