Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of faucet accessories and relates to a faucet valve core structure. Background Technology
[0002] The current faucet has a built-in valve core that is linked to the faucet switch knob via a linkage. The valve core has a stud that connects to the inner wall of the faucet housing. Adjusting and turning the switch knob causes the stud and the valve core on the stud to rise and fall. The valve core blocks or opens the valve port inside the faucet, thereby achieving the purpose of turning the water on and off.
[0003] Currently, the sealing between the valve core and the valve port when the water is turned off is achieved by installing a sealing ring on the valve core. However, this sealing ring is prone to dislocation and falling off during the back-and-forth switching motion, affecting its use. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a novel valve core structure with a sealing element for use in faucets.
[0005] The purpose of this utility model can be achieved through the following technical solution: A faucet valve core structure, the faucet including a housing, a water outlet end and a water inlet end, the housing having a valve port connecting the water inlet and outlet ends, characterized in that the valve core structure includes a valve core component disposed inside the housing, a stud threaded to the housing, and a screw rod connected to the stud, the lower end of the valve core component having a conical truncated structure, and the lower end of the valve core component extending into the valve port and forming a seal with the housing, a sealing groove being provided inside the housing near the valve port, and a sealing element being inserted into the sealing groove, the outer ring of the sealing element having an outwardly protruding sealing lip, the inner ring of the sealing ring having multiple outwardly protruding sealing inner lips, the housing having an annular groove for the sealing outer lip to enter, multiple grooves for the sealing inner lips to enter being formed on the peripheral wall of the lower end of the valve core component, and a pressing element installed inside the housing at the upper end of the sealing element to prevent the sealing element from falling off.
[0006] In the aforementioned faucet valve core structure, the longitudinal section of the valve port is also a tapered structure.
[0007] In the aforementioned faucet valve core structure, the pressure member is connected to the housing by screws.
[0008] In one of the aforementioned faucet valve core structures, an adjusting handwheel connected to a screw is provided outside the housing.
[0009] Compared with existing technologies, the valve core structure of this faucet has the advantage of improving sealing stability, thereby improving sealing performance. Attached Figure Description
[0010] Figure 1This is a cross-sectional view of the valve core structure of this faucet.
[0011] Figure 2 yes Figure 1 Enlarged view of point A.
[0012] In the diagram, 1 is the housing; 2 is the outlet; 3 is the inlet; 4 is the valve port; 5 is the valve core; 6 is the stud; 7 is the screw; 8 is the seal; 9 is the outer sealing lip; 10 is the inner sealing lip; 11 is the groove; 12 is the pressing part; and 13 is the adjusting handwheel. Detailed Implementation
[0013] 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.
[0014] like Figure 1 , Figure 2 As shown, the faucet valve core structure includes a housing 1, an outlet end 2, and an inlet end 3. The housing 1 has a valve port 4 connecting the inlet and outlet ends 2. The valve core structure includes a valve core component 5 disposed inside the housing 1, a stud 6 threadedly connected to the housing 1, and a screw 7 connected to the stud 6. The lower end of the valve core component 5 has a truncated cone shape and extends into the valve port 4 to form a seal with the housing 1. A sealing groove is provided inside the housing 1 near the valve port 4, and a sealing element 8 is inserted into this groove. The outer ring of the sealing element 8 has a protruding sealing lip 9, and the inner ring of the sealing ring has multiple protruding sealing lips 10. The housing 1 has an annular groove for the outer sealing lip 9 to enter. The lower end of the valve core 5 has multiple grooves 11 formed on its peripheral wall for the inner sealing lip 10 to enter. Inside the housing 1, a pressing member 12 is installed at the upper end of the sealing member 8 to prevent the sealing member 8 from falling off. The pressing member 12 positions the sealing member 8 to prevent it from shifting or falling off. In addition, the sealing member 8 is made of silicone material. Therefore, when the valve core 5 blocks the valve port 4, the grooves 11 on the valve core 5 and the inner sealing lip 10 on the sealing member 8 form a corresponding connection seal to achieve high-efficiency sealing. In addition, the outer sealing lip 9 plays a certain role in positioning and sealing with the housing 1.
[0015] Preferably, the longitudinal section of valve port 4 is also a conical structure.
[0016] Preferably, the pressing member 12 is connected to the housing 1 by screws.
[0017] Preferably, the housing 1 is provided with an adjusting handwheel 13 connected to the screw 7.
[0018] 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.
[0019] Although this document frequently uses terms such as housing 1, outlet 2, inlet 3, valve port 4, valve core 5, stud 6, screw 7, seal 8, outer sealing lip 9, inner sealing lip 10, groove 11, pressing part 12, and adjusting handwheel 13, 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.
