Description

Technical Field

[0001] This utility model relates to the technical field of water purifiers, and in particular to a central tube with a flange to prevent deformation and leakage. Background Technology

[0002] With the improvement of people's living standards and increased emphasis on water quality safety, water purifiers have become essential equipment in many households and places. In the development of water purifiers, to meet users' needs for compact size and minimal space occupation while improving purification efficiency, composite filter technology has emerged and gained widespread application. Composite filters integrate multiple filter elements with different functions into one unit, effectively reducing the overall size of the water purifier and overcoming the drawbacks of traditional single-filter systems that result in bulky water purifiers.

[0003] During use, the central tube is prone to significant deformation due to its large surface area exposed to water pressure. This deformation not only affects the structural stability of the central tube itself but also increases the risk of leakage. Once a leak occurs, it will not only reduce the purification effect of the water purifier but may also damage the surrounding environment and even affect the user's normal use. Utility Model Content

[0004] In view of the above-mentioned problems of existing center tubes, the aim is to provide a center tube with a flange to prevent deformation and leakage.

[0005] The specific technical solution is as follows:

[0006] A central tube with a deformation-resistant and leakage-proof flange includes: a central tube body, wherein the central tube body has a flange structure, the flange structure includes a stepped portion extending radially inward from the inner wall of the central tube body and an extension portion extending axially to one side from the inner wall of the stepped portion, wherein the central tube body, the stepped portion and the extension portion are an integral structure.

[0007] As a further improvement and optimization of this solution, the inner wall of the extension portion facing away from the opening of the stepped portion is flared.

[0008] As a further improvement and optimization of this solution, the central tube body has several flow guide holes on the inner wall of the side of the stepped portion away from the extension portion.

[0009] As a further improvement and optimization of this solution, several of the flow guide holes are distributed on the periphery of the central tube body.

[0010] As a further improvement and optimization of this solution, the outer wall of the central tube body at the end away from the extension is rounded.

[0011] As a further improvement and optimization of this solution, the outer wall of the end of the central tube body away from the extension has a sealing groove.

[0012] As a further improvement and optimization of this solution, the sealing groove has two sections, which are spaced apart along the axial direction of the central tube body.

[0013] As a further improvement and optimization of this solution, the outer wall of the central tube is provided with several elongated grooves distributed circumferentially.

[0014] As a further improvement and optimization of this solution, several of the elongated grooves are located on the side of the stepped portion facing the extension portion.

[0015] As a further improvement and optimization of this solution, the length direction of each of the elongated grooves is parallel to the axial direction of the central tube.

[0016] The positive effects of the above technical solution compared with the existing technology are:

[0017] The integrated structure of the central tube body of this utility model enhances the overall strength and stability of the central tube, and the flange structure can effectively reduce the impact of the draft angle caused by the change in the length of the central tube on the internal seal.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0024] Figure 1 This is a schematic diagram of the structure of a central tube with an anti-deformation and leakage flange according to the present invention. Figure 2 This is a cross-sectional view of a flange with anti-deformation and leakage protection according to the present invention, as shown below. Figure 1-2 The diagram illustrates a preferred embodiment of a central tube with an anti-deformation and leakage flange, comprising: a central tube body 1, and a flange structure 2 within the central tube body 1. The flange structure 2 includes a stepped portion 21 extending radially inward from the inner wall of the central tube body, and an extension portion 22 extending axially to one side from the inner wall of the stepped portion 21. The central tube body 1, the stepped portion 21, and the extension portion 22 are integrally formed. This integral structure increases the overall strength and stability of the central tube, reduces gaps caused by loose component connections, thereby lowering the risk of leakage. Simultaneously, the flange structure 2 enhances the central tube's resistance to deformation, effectively addressing deformation issues caused by factors such as water pressure, and ensuring the performance stability of the central tube during long-term use.

[0025] Even better, the reduced flange area will reduce the water pressure it experiences during use, resulting in less deformation and a lower risk of leakage.

[0026] Furthermore, in a preferred embodiment, the inner wall of the extension 22 facing away from the opening of the stepped portion 21 is flared. The flared design allows water to flow more smoothly through the central pipe, reducing the impact force of the water flow on the extension 22, further reducing the possibility of the central pipe deforming due to water flow impact, thereby effectively preventing leakage.

[0027] Furthermore, as a preferred embodiment, the inner wall of the central tube body 1 on the side of the stepped portion 21 opposite to the extension portion 22 has a plurality of guide holes 11. The arrangement of the guide holes 11 can reasonably guide the water flow direction, making the water flow more evenly distributed in the central tube, avoiding damage to the central tube caused by excessive local water flow pressure, and at the same time helping to improve water purification efficiency.

[0028] Furthermore, as a preferred embodiment, a plurality of guide holes 11 are distributed on the periphery of the central tube body 1. The guide holes 11 distributed on the periphery can guide the water flow from multiple directions, so that the water flow forms a more uniform flow state in the central tube, further optimizing the water flow path, reducing the scouring of the inner wall of the central tube by the water flow, and reducing the risk of deformation and leakage.

[0029] Furthermore, as a preferred embodiment, the outer wall of the end of the central tube body 1 away from the extension 22 is rounded. The rounded corners make the installation of the central tube smoother, reduce friction and collisions with surrounding components, prevent damage to the central tube due to improper installation, and also help improve installation efficiency.

[0030] Furthermore, as a preferred embodiment, the outer wall of the end of the central tube body 1 furthest from the extension 22 has a sealing groove 12. The sealing groove 12 facilitates the installation of seals, effectively enhances the sealing performance between the central tube and surrounding components, prevents water leakage from the connection, and improves the sealing reliability of the entire composite filter element.

[0031] Furthermore, as a preferred embodiment, there are two sealing grooves 12, which are spaced apart along the axial direction of the central tube body 1. The two spaced sealing grooves 12 form a double sealing structure, which further improves the sealing effect. Even if one of the seals ages or is damaged, the other seal can still play a sealing role, greatly reducing the possibility of leakage and ensuring the normal operation of the water purifier.

[0032] Furthermore, as a preferred embodiment, the outer wall of the central tube is provided with a plurality of elongated grooves 13 distributed circumferentially. The arrangement of the elongated grooves 13 increases the surface area of ​​the outer wall of the central tube, which can enhance the friction and adhesion between the central tube and the surrounding medium (such as filter material) when the central tube is in contact with it, making the connection between the central tube and the filter element more stable, reducing the risk of separation between the central tube and the filter element due to water flow impact or vibration, and also helping to improve heat exchange efficiency (if a heat exchange process is involved).

[0033] Furthermore, as a preferred embodiment, several elongated grooves 13 are located on the side of the stepped portion 21 facing the extension portion 22. Positioning the elongated grooves 13 in this location can specifically enhance the structural strength of the transition area between the stepped portion 21 and the extension portion 22, while simultaneously increasing the contact area with the surrounding medium in this area, further improving the stability and connection reliability of this critical component, and effectively preventing deformation and leakage problems caused by stress concentration in this area.

[0034] Furthermore, as a preferred embodiment, the length direction of each elongated groove 13 is parallel to the axial direction of the central tube. The parallel axial arrangement of the elongated grooves 13 enables the central tube to better disperse stress when subjected to axial forces (such as water flow pressure, installation force, etc.), avoiding stress concentration in local areas, thereby reducing the deformation of the central tube caused by axial forces, further improving the structural stability and deformation resistance of the central tube, and ensuring the normal operation of the central tube under various working conditions.

[0035] 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.
