Description

Technical Field

[0001] This utility model belongs to the field of faucet technology, and relates to a faucet valve core, and particularly to a novel faucet valve core. Background Technology

[0002] Currently, the valve core inside the faucet usually has a sealing structure between the temperature control handwheel and the housing. However, this sealing structure is relatively simple and is prone to wear during the rotation and adjustment of the temperature control handwheel, which affects the sealing performance. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel faucet valve core that improves sealing performance.

[0004] The objective of this utility model can be achieved through the following technical solution: A novel faucet valve core, comprising a housing and a handwheel assembly connected within the housing, characterized in that the housing is provided with an installation sleeve into which the bottom end of the handwheel assembly extends; a sealing structure is provided between the installation sleeve and the housing; a sealing groove is provided on the installation sleeve for positioning and installation of the sealing structure; the sealing structure includes an outer sealing ring and an inner sealing ring; the inner sealing ring is higher than the outer sealing ring; and the outer sealing ring and the inner sealing ring are integrally connected by a plurality of spaced sealing connecting ribs; a spacer groove is provided between two adjacent sealing connecting ribs; the sealing groove has a plurality of protrusions integral with the installation sleeve; and the plurality of protrusions correspond one-to-one with the plurality of spacer grooves; the sealing structure is positioned and installed in the sealing groove by the engagement of the protrusions with the spacer grooves; the inner sealing ring seals between the fixed sleeve and the inner wall A of the housing; and the outer sealing ring seals between the fixed sleeve and the inner wall B of the housing.

[0005] In the aforementioned novel faucet valve core, both the inner and outer sealing rings have waterproof chamfers at their ends.

[0006] Compared with existing technologies, this new type of faucet valve core has the advantages of preventing wear of the sealing ring and improving sealing performance. Attached Figure Description

[0007] Figure 1 This is a cross-sectional view of the new type of faucet valve core.

[0008] Figure 2 This is a 3D view of the installation kit.

[0009] Figure 3 It is a 3D diagram of the sealed structure.

[0010] In the diagram, 1 is the housing; 2 is the handwheel assembly; 3 is the mounting sleeve; 4 is the sealing groove; 5 is the outer sealing ring; 6 is the inner sealing ring; 7 is the sealing connecting rib; and 8 is the boss. Detailed Implementation

[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0012] like Figure 1 , Figure 2 , Figure 3 As shown, this novel faucet valve core includes a housing 1 and a handwheel assembly 2 connected within the housing 1. A mounting sleeve 3 is provided within the housing 1 for the bottom end of the handwheel assembly 2 to extend into. A sealing structure is provided between the mounting sleeve 3 and the housing 1. A sealing groove 4 is provided on the mounting sleeve 3 for positioning and mounting the sealing structure. The sealing structure includes an outer sealing ring 5 and an inner sealing ring 6, with the inner sealing ring 6 being higher than the outer sealing ring 5. The outer sealing ring 5 and the inner sealing ring 6 are integrally connected by several spaced-apart sealing connecting ribs 7. A spacer groove is provided between two adjacent sealing connecting ribs 7. The sealing groove 4 contains a groove that connects with the mounting sleeve 3. The system consists of several integrated bosses 8, each corresponding to a specific spacer groove. The sealing structure is positioned and installed within the sealing groove 4 through the engagement of the bosses 8 with the spacer grooves. The inner sealing ring 6 seals between the fixed sleeve and the inner wall A of the housing 1, while the outer sealing ring 5 seals between the fixed sleeve and the inner wall B of the housing 1. The sealing structure is supported and positioned through the engagement of the bosses 8 with the spacer grooves. Furthermore, the design of the sealing structure with its height difference effectively prevents water from entering the handwheel assembly 2, and the sealing structure will not wear out. The adjusting threads of the handwheel assembly 2 will also not rust due to contact with water.

[0013] Preferably, both the inner sealing ring 6 and the outer sealing ring 5 have waterproof chamfers at their ends.

[0014] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0015] Although this document frequently uses terms such as housing 1, handwheel assembly 2, mounting sleeve 3, sealing groove 4, sealing outer ring 5, sealing inner ring 6, sealing connecting rib 7, and boss 8, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
