Description

Technical Field

[0001] This utility model relates to the technical field of water purifiers, and in particular to an auxiliary fixing structure for a screw-in filter bottle in a water purifier. Background Technology

[0002] In existing water purifier equipment, screw-in filter bottles are a common type of filter bottle installation. They are screwed into the interface of the water circuit board by axial rotation, and the filter bottle is fixed to the water circuit board by the cooperation of the screw-in structure and the sealing ring.

[0003] However, this installation method has many limitations. On the one hand, the filter bottle can only be placed vertically during operation. If it is placed on its side, the weight of the filter bottle itself will cause the sealing ring in the interface to be subjected to force on one side, which will lead to the risk of water leakage. On the other hand, during long-term use, the screw-in filter bottle will be subjected to the impact of long-term switching between high and low pressure, which can easily cause clockwise rotation, causing the filter bottle to fall out of the interface and cause water leakage.

Figure 2 This is a top sectional view of an auxiliary fixing structure for a screw-in filter bottle in a water purifier according to the present invention. Figure 3 This is a schematic diagram of the vertical installation of a screw-in filter bottle auxiliary fixing structure for a water purifier according to the present invention. Figure 4 This is a schematic diagram of the horizontal installation of a screw-in filter bottle auxiliary fixing structure for a water purifier according to this utility model. Figure 1-4 The diagram illustrates a preferred embodiment of an auxiliary fixing structure for a screw-in filter bottle 2 in a water purifier. This structure is used to auxiliaryly fix the filter bottle 2, which has a screw-in water circuit board structure, to the main structure 3 of the water purifier. The structure includes at least one arcuate rib 1, at least one retaining ring 4, and at least one silicone gasket 5. The arcuate rib 1 is connected to the main structure 3 of the water purifier, and its inner arc surface matches the outer circumferential surface of the filter bottle 2. Both ends of the arcuate rib 1 have limiting portions 11, the minimum distance between the two limiting portions 11 matches the diameter of the filter bottle 2, and the two limiting portions 11 respectively limit and cooperate with the two sides of the filter bottle 2. The retaining ring 4 has a semi-arc structure and is positioned opposite the arcuate rib 1. The retaining ring 4 is detachably connected to the arcuate rib 1. The inner arc surface of the retaining ring 4 has several abutting ribs 42 along its circumferential direction, each abutting rib 42 abutting against the outer wall of the filter bottle 2. The silicone gasket 5 is disposed on the inner arc surface of the retaining ring 4 and elastically abuts against the outer wall of the filter bottle 2.

[0023] In this application, the cooperation between the arc rib 1 and the retaining ring 4 can support, limit and lock the waist position of the filter bottle 2, so that the circular interface between the filter bottle 2 and the water circuit board always remains concentric. Even if the filter bottle 2 is placed on its side, it can avoid the interface sealing ring being subjected to force on one side, reducing the risk of water leakage. The silicone gasket 5 elastically abuts against the outer wall of the filter bottle 2, which can prevent the filter bottle 2 from rotating out clockwise during long-term use. At the same time, the detachable retaining ring 4 is convenient for disassembly and assembly, which helps to improve the concentricity and sealing of the filter bottle 2 and the water circuit interface.

[0024] Furthermore, as a preferred embodiment, the silicone gasket 5 is an arc-shaped gasket that matches the outer circumferential surface of the filter bottle 2. The arc-shaped gasket's match with the outer circumferential surface of the filter bottle 2 allows for better contact with the filter bottle 2, providing uniform elastic resistance, further enhancing the fixation effect on the filter bottle 2, and reducing the risk of the filter bottle 2 rotating out.

[0025] Furthermore, as a preferred embodiment, the arc-shaped gasket is located at the center of the inner arc surface of the retaining ring 4. Positioning the arc-shaped gasket at the center of the inner arc surface of the retaining ring 4 allows for a more uniform distribution of the elastic resistance force on the filter bottle 2, ensuring the stability of the filter bottle 2 in all directions and improving the reliability of the fixing structure.

[0026] Furthermore, in a preferred embodiment, the inner arc surface of the retaining ring 4 has two limiting ribs 43, and the two limiting ribs 43 and the inner arc surface of the retaining ring 4 form an installation groove, in which the silicone gasket 5 is disposed. By setting the limiting ribs 43 to form an installation groove to install the silicone gasket 5, the position of the silicone gasket 5 can be accurately fixed, preventing the silicone gasket 5 from shifting during use, ensuring that the silicone gasket 5 always effectively and elastically contacts the outer wall of the filter bottle 2, and improving the stability of the fixing structure.

[0027] Furthermore, as a preferred embodiment, each abutment rib 42 has an abutment arc surface at its end away from the inner arc surface of the retaining ring 4. The abutment arc surface matches the outer circumferential surface of the filter bottle 2. Matching the abutment arc surface at the end of the abutment rib 42 with the outer circumferential surface of the filter bottle 2 can increase the contact area between the abutment rib 42 and the outer wall of the filter bottle 2, making the abutment force more evenly distributed on the outer wall of the filter bottle 2, enhancing the fixing effect on the filter bottle 2, and reducing the possibility of the filter bottle 2 shaking and rotating.

[0028] Furthermore, in a preferred embodiment, each limiting part 11 has a mounting part 12 on its outer side, and each end of the retaining ring 4 has a fixing part 41 on its outer side. The two fixing parts 41 are connected to the two mounting parts 12 by screws 6. By using screws 6 to connect the mounting parts 12 and the fixing parts 41, the retaining ring 4 and the arc rib 1 can be detachably connected. This connection method is firm and reliable, and easy to disassemble and assemble, making it convenient to install, maintain and replace the filter bottle 2.

[0029] Of course, in some embodiments, the mounting part 12 and the fixing part 41 can also be detachably connected by a snap-fit ​​structure.

[0030] Furthermore, in a preferred embodiment, one end of the mounting part 12 has a threaded hole 112, and one end of the fixing part 41 has a positioning groove 411. One end of the mounting part 12 is positioned and engaged with the positioning groove 411, and the screw 6 passes through the other end of the fixing part 41 and is threaded into the threaded hole 112. The positioning groove 411 of the mounting part 12 and the positioning engagement of the fixing part 41 enable quick and accurate positioning of the retaining ring 4 and the arc rib 1 during installation, improving installation efficiency. The screw 6 passes through the fixing part 41 and is threaded into the threaded hole 112, ensuring the stability and reliability of the connection, and enabling the fixing structure to better withstand the weight of the filter bottle 2 and various external forces.

[0031] Furthermore, as a preferred embodiment, the other end of the fixing part 41 has an inner countersunk hole 412 communicating with the positioning groove 411, and the screw 6 is disposed in the inner countersunk hole 412. The setting of the inner countersunk hole 412 allows the head of the screw 6 to be hidden in the fixing part 41, avoiding the screw head protruding and interfering with other components. It also makes the appearance of the fixing structure neater and more beautiful, and to a certain extent protects the screw 6, preventing it from loosening due to external impact.

[0032] Furthermore, as a preferred embodiment, the threaded hole 112 is a blind hole. The blind hole design of the threaded hole 112 prevents impurities and moisture from entering the interior of the threaded hole 112, avoiding corrosion and damage to the screw 6 and the threads, extending the service life of the fixing structure, and ensuring the reliability of the connection.

[0033] Furthermore, as a preferred embodiment, two arc ribs 1 are provided, and the two arc ribs 1 are connected by a mounting part 12. Two retaining rings 4 are provided accordingly, and the two retaining rings 4 are connected by a fixing part 41. This can achieve simultaneous auxiliary fixing of two filter bottles 2. Of course, in some embodiments, in order to meet the auxiliary fixing requirements of multiple filter bottles 2, multiple arc ribs 1 and retaining rings 4 can be provided accordingly.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
