Description

Technical Field

[0001] The utility model belongs to the technical field of faucet valve cores, and particularly relates to a novel faucet valve core. Background Art

[0002] Faucet valve cores are widely used and have the function of controlling the on-off of water flow. The Chinese invention patent with the patent number CN200610026148.8 and the name of a faucet discloses a faucet. A valve core assembly and a valve core base are arranged on the valve seat of the faucet. The valve core base is provided with a first water inlet hole and a first water outlet hole. An adjusting handle is also arranged on the main faucet housing. The valve core assembly includes a fixed valve plate, a moving valve plate, a guide seat, a transmission seat and a rocker. A water groove is formed on the moving valve plate. The moving valve plate and the guide seat are buckled with each other. The fixed valve plate is provided with a second water inlet hole and a second water outlet hole. A blocking block is also arranged in the water groove of the moving valve plate. The blocking block divides the water groove into a water inlet groove and a water outlet groove. A water channel connecting the water inlet groove and the water outlet groove is formed above the water groove. The second water outlet hole of the fixed valve plate is arranged towards the direction close to the water outlet pipe. The valve core base is arranged in a matching manner with the fixed valve plate, and its first water outlet hole is aligned with the second water outlet hole close to the water outlet pipe. The water outlet groove of the moving valve plate is also arranged in a matching manner with the fixed valve plate at a position close to the water outlet pipe.

[0003] However, the above patent still has the following technical problems: 1. Since the above patent forms a valve rod for driving the moving valve plate through the mutual assembly between the guide seat, the transmission seat and the rocker, this form of design results in the overall structure of the valve rod being too complex and the connection relationship between each component not being tight enough, which is easy to be damaged after long-term use; 2. The connection relationship between the guide seat and the moving valve plate described in the above patent is only in a transmission connection by mutual buckling, and this connection relationship has poor stability; 3. The overall sealing performance is poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a novel faucet valve core to solve the above technical problems.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a novel faucet valve core, including a valve core housing. A valve rod, a moving valve plate, a fixed valve plate and a base are sequentially arranged in the valve core housing from top to bottom. A plurality of water passing holes are formed on the base. The valve rod includes a valve handle and a guide seat integrally connected with the valve handle. The valve rod is rotatably arranged in the valve core housing. One end of the valve handle far away from the guide seat extends out of the valve core housing. A water passing groove is formed on the moving valve plate. The moving valve plate is installed below the guide seat and drives the moving valve plate to rotate. The fixed valve plate is provided with a water inlet hole and a water outlet hole corresponding to the water passing holes. The fixed valve plate is installed in the middle of the base. Clamping mechanisms that cooperate with each other are respectively arranged on the edge of the fixed valve plate and the base.

[0006] Furthermore, the water overflow tank is a bone-shaped water overflow tank. The bone-shaped water overflow tank includes a middle narrow area and fan-shaped areas on both sides of the middle narrow area. Both the water inlet hole and the water outlet hole are fan-shaped in extension. When in the water-stop state, the water overflow tank, the water inlet hole, and the water outlet hole are misaligned, and water flow cannot enter the water overflow tank. When in the water-passing state, the water overflow tank, the water inlet hole, and the water outlet hole correspond to each other, and water flow flows into the water overflow tank from the water inlet hole and is discharged from the water outlet hole.

[0007] Furthermore, a first positioning groove is provided at one end of the movable valve plate away from the water overflow tank, and a clamping block is provided below the guide seat.

[0008] Furthermore, positioning notches are formed on both sides of the upper surface of the movable valve plate, and positioning blocks matching the positioning notches are provided on the guide seat. When the movable valve plate is installed below the guide seat, the clamping block extends into the first positioning groove, and the positioning block is clamped into the positioning notch.

[0009] Furthermore, the clamping mechanism includes a plurality of second positioning grooves formed on the outer surface of the fixed valve plate and a plurality of positioning columns provided on the base. A receiving chamber for placing the fixed valve plate is formed between the plurality of positioning columns. When the fixed valve plate is installed in the receiving chamber, the positioning columns are clamped in the second positioning grooves.

[0010] Furthermore, a plurality of bayonet openings are formed at the bottom of the valve core housing. A hook is provided on one side of the positioning column corresponding to the bayonet opening. A notch is provided below the valve core housing, and a limiting end matching the notch is provided on the upper surface of the base. When the base is fixed below the valve core housing, the hook is clamped into the bayonet opening, and the limiting end extends into the notch.

[0011] Furthermore, a plurality of valve core positioning columns for installing the valve core are provided on the lower surface of the base.

[0012] Furthermore, a plurality of grease grooves are formed on the upper surface of the fixed valve plate.

[0013] Furthermore, a first D-shaped sealing groove and a second D-shaped sealing groove are respectively formed at the upper and lower ends of the base, and a first D-shaped valve core ring and a second D-shaped valve core ring are respectively provided in the first D-shaped sealing groove and the second D-shaped sealing groove.

[0014] Furthermore, a plurality of small sealing rings are sleeved on the valve handle, a wear-resistant ring is sleeved on the upper end of the guide seat, and a large sealing ring is sleeved outside the valve core housing.

[0015] With the above technical solution, compared with the prior art, the utility model has the following beneficial effects: 1. By providing an integrated valve handle and guide seat, the valve stem structure is made simpler. Specifically, the valve handle is provided on the upper surface of the guide seat, one end of the valve handle extends out of the valve core housing, and the end surface of the guide seat away from the valve handle is connected to the moving valve plate and is used to drive the moving valve plate to rotate. The above method not only avoids the technical problem that the connection relationship between components in the prior art is not tight enough and is easily damaged, but also reduces the corresponding steps during the product assembly process, making the assembly faster and increasing the work efficiency during product assembly.

[0016] 2. By providing a clamping block and a positioning block at the lower end of the guide seat and providing a positioning notch and a first positioning groove corresponding to the positioning block and the clamping block respectively on the moving valve plate. Generally, two clamping blocks are provided. When the guide seat and the moving valve plate are connected, the two clamping blocks are respectively clamped on both sides of the first positioning groove, and at the same time, the positioning block will also be correspondingly buckled into the positioning notch. At this time, when the valve stem rotates, it will drive the lower guide seat to make corresponding movements. Furthermore, the guide seat drives the moving valve plate to rotate through the cooperation of the clamping block, the positioning block, the first positioning groove and the positioning notch. The above method not only realizes the transmission through the cooperation of the positioning notch and the positioning block, but also further adds the cooperation of the clamping block and the first positioning groove, making the connection relationship between the guide seat and the moving valve plate more stable and the transmission effect better.

[0017] 3. By providing a bone-shaped water passing groove at one end of the moving valve plate away from the first positioning groove, and providing fan-shaped water inlet holes and water outlet holes corresponding to the fan-shaped areas on both sides of the bone-shaped water passing groove on the fixed valve plate.
