Description

Technical Field

[0001] This utility model relates to the field of valve body shaft technology, specifically an eccentric shaft that is oil-resistant, dirt-resistant, scale-resistant, impurity-proof, and waterproof. Background Technology

[0002] After prolonged use, traditional water valves accumulate a large amount of scale inside, especially at the connection between moving parts and the valve. Scale buildup can prevent the moving parts from moving properly, thus causing the water valve to malfunction.

[0003] For example, announcement number CN222121895U describes a scale prevention structure for a switching valve body, comprising: a water pump base shell, a rotating cylinder extending through the water pump base shell, the rotating cylinder protruding from the bottom of the water pump base shell, and an eccentric shaft rotatably disposed within the rotating cylinder; the eccentric shaft includes a sealing shaft and a rotating shaft, the sealing shaft being rotatably disposed within the rotating cylinder, a turntable connecting the bottom of the sealing shaft and the top of the rotating shaft, and a valve body rotatably sleeved on the rotating shaft; a rubber sleeve is wrapped around the turntable, the top of the rubber sleeve abutting against the bottom of the rotating shaft, and the bottom of the rubber sleeve fitting against the valve body;

[0004] The aforementioned specially structured rubber sleeve effectively prevents scale from adhering to the moving parts and connections of the water pump, thus maintaining the normal operation of the pump. It also helps resist wear and deformation caused by long-term use and water pressure changes, thereby improving the pump's durability and reliability. However, its shaft structure is a split structure, and a sealing disc is also installed between the drive shaft and the valve shaft. The three sets of structures are separate and fixedly connected to each other, which makes it easy for gaps to appear at the connection after long-term use. This weakens the pump's oil resistance, dirt resistance, scale resistance, impurity resistance, and waterproofing capabilities, affecting its use. Therefore, the market urgently needs to develop an eccentric shaft that is oil-resistant, dirt-resistant, scale-resistant, impurity-resistant, and waterproof to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide an eccentric shaft that is oil-resistant, dirt-resistant, scale-resistant, impurity-proof, and waterproof, in order to solve the problem mentioned in the background art that most of the current valve body shafts are split structures, and a sealing disc is also set between the drive shaft and the valve shaft. The three sets of structures are separate and fixedly connected to each other, which leads to gaps easily appearing at the connection after a long period of use, weakening the oil-resistant, dirt-resistant, scale-resistant, impurity-proof, and waterproof capabilities, thus affecting the use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an eccentric shaft that is oil-resistant, dirt-resistant, scale-resistant, impurity-proof, and waterproof, comprising a valve body bottom shell on which the eccentric shaft body is mounted, the eccentric shaft body comprising a drive shaft, a sheath, and a valve shaft, wherein the drive shaft and the valve shaft are both integrally formed with the drive shaft body, and the sheath is manufactured using an injection molding process.

[0007] Through the above technical solution, the traditional valve body's eccentric shaft is improved from a three-part structure to a one-piece structure, and the traditional rotary table structure is eliminated. The drive shaft, sheath, and valve shaft are directly manufactured by injection molding. The sheath is integrated with the eccentric shaft body, so there are no connection gaps in the overall structure. No gaps will appear after long-term use, thereby improving sealing performance, oil resistance, dirt resistance, scale resistance, impurity prevention, and waterproofing, and improving the performance.

[0008] In a preferred embodiment, the present invention can be further configured such that a connector is provided at the top of the drive shaft.

[0009] Through the above technical solution, the connector is used to connect the drive mechanism to drive the eccentric shaft to rotate.

[0010] In a preferred embodiment, the present invention can be further configured such that: a sealing groove is provided on the outer side of the drive shaft, and a sealing ring is provided on the inner side of the sealing groove.

[0011] The above technical solution utilizes sealing grooves and sealing rings to improve sealing performance.

[0012] In a preferred embodiment, the present invention can be further configured such that a shaft head is provided at the bottom of the valve shaft body.

[0013] The above technical solution uses the shaft head to fix the valve ball of the valve body.

[0014] In a preferred embodiment, the present invention can be further configured such that: the drive shaft of the eccentric shaft body is rotatably connected to the bottom shell of the valve body, and the sheath is disposed below the bottom shell of the valve body.

[0015] With the above technical solution, the drive shaft is installed inside the valve body bottom shell and sealed with a sealing ring. At the same time, the sheath will fit against the bottom of the valve body bottom shell, which also achieves the same sealing effect.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model improves the traditional valve body's eccentric shaft from a three-part structure into a single integrated structure, and eliminates the traditional rotary table structure. The drive shaft, sheath, and valve shaft are directly manufactured by injection molding, and the sheath is integrated with the eccentric shaft body. As a result, there are no gaps in the overall structure, and no gaps will appear after long-term use. This improves sealing performance, oil resistance, dirt resistance, scale resistance, and waterproofing, thereby enhancing the overall performance. Attached Figure Description
