Description
Technical Field
[0001] The utility model relates to the technical field of switch valve cores, in particular to a simple switch valve core. Background Art
[0002] The valve core is a key component in a valve, and it controls direction, pressure or flow rate through its own movement. Although the existing switch valve cores on the market have rich functions, they often have complex structures and high costs. Under different water pressure conditions, the operating force of the valve core will change significantly, which affects its applicability in different application scenarios. In addition, the existing valve cores are relatively large in size and can usually only be installed on faucets, and are not suitable for other components such as handles. Therefore, it is particularly important to develop a new type of switch valve core with a simple structure, low cost and suitable for a variety of operating environments. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a simple switch valve core.
[0004] To solve the above technical problems, the utility model provides the following technical solutions:
[0005] A simple switch valve core of the utility model includes an installation housing, characterized in that: an external thread is provided on the outer surface of the installation housing, a pressing block is sleeved on the upper end of the installation housing, a moving block is movably connected to the lower end of the pressing block, four first support ribs are provided at the lower end of the moving block, a groove body is provided inside the installation housing, and the four first support ribs respectively abut against the groove body. A moving rod is fixedly connected to the lower end of the moving block. A water flow guiding block is clamped at the lower end inside the installation housing. A support block is further provided between the water flow guiding block and the inner surface of the installation housing. The lower end of the moving rod sequentially passes through the support block and the water flow guiding block and is fixedly connected to a blocking block. A spring is installed between the upper surface of the support block and the moving block, and the spring is sleeved outside the moving rod.
[0006] As a preferred technical solution of the utility model, the groove body includes four buffer grooves and four valve closing grooves arranged at equal intervals. The four buffer grooves are all inclined, and the four first support ribs are in clearance fit with the four valve closing grooves respectively.
[0007] As a preferred technical solution of the utility model, the upper surfaces of the four first support ribs are all inclined and are respectively adapted to the four buffer grooves.
[0008] As a preferred technical solution of the present utility model, four second support ribs are equidistantly arranged on the outer side of the pressing block, and the four second support ribs always move in the corresponding valve closing grooves. A ring-shaped tooth body is arranged on the lower surface of the pressing block, and the ring-shaped tooth body is adapted to the upper surface of the first support rib.
[0009] As a preferred technical solution of the present utility model, a first sealing ring is connected to the outer surface of the installation housing.
[0010] As a preferred technical solution of the present utility model, a second sealing ring is connected between the installation housing and the water flow guiding block.
[0011] As a preferred technical solution of the present utility model, a third sealing ring is connected between the water flow guiding block and the moving rod.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] During use, when the pressing block is pressed for the first time and the valve core is in the initial closed position, both the second support rib and the first support rib are located in the corresponding valve closing grooves. When the pressing block is pressed again, the pressing block moves downward, driving the moving block and the first support rib to move downward. When the first support rib leaves the valve closing groove, the ring-shaped tooth body at the lower end of the pressing block will drive the upper surface of the first support rib to rotate a small angle. At this time, after the first support rib rotates a small angle, it immediately enters the buffer groove through the inclined shape of the corresponding buffer groove for limiting. At this time, the moving block is limited and moves downward by a certain distance relative to the initial position. Therefore, the moving rod will also be driven to move downward during the downward movement. After the moving rod moves downward, it drives the blocking block to disengage from the water flow guiding block. At this time, the valve core is in the open state, and water flows in through the lower end of the water flow guiding block and then flows out through the side surface of the water flow guiding block. Similarly, after the pressing block is pressed again, under the action of the spring elasticity, the first support rib returns to the valve closing groove, and the blocking block blocks the water flow guiding block, realizing the closing of the valve core. This simple type of switch valve core can achieve a quick state switch after pressing. Through the design of multiple sealing rings, the sealing performance is improved, and there will be no water overflow or leakage. The valve core is small in size and can be used in small faucets or different scenarios such as installing handles. This switch valve core has a simple structure, low cost and is applicable to a variety of operating environments. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0021] Such as Figures 1 - 3As shown in the figure, a simple switch valve core of the present utility model includes an installation housing 1. The outer surface of the installation housing 1 is provided with external threads, and the switch valve core can be installed on a faucet or a handle through the external threads. A first sealing ring 14 is connected to the outer surface of the installation housing 1 to improve the sealing performance of the outer wall of the valve core, making the water outlet more concentrated and preventing water leakage or overflow. A pressing block 2 is sleeved on the upper end of the installation housing 1. The lower end of the pressing block 2 is movably connected to a moving block 3. Pressing the pressing block 2 can drive the moving block 3 to move simultaneously. Four first supporting ribs 4 are arranged at the lower end of the moving block 3. A groove body 5 is provided inside the installation housing 1. In the initial state, the four first supporting ribs 4 are respectively in contact with the groove body 5. After pressing the pressing block 2, the four first supporting ribs 4 move in the groove body 5. A moving rod 6 is fixedly connected to the lower end of the moving block 3. A water flow guiding block 8 is clamped at the lower end inside the installation housing 1. A second sealing ring 15 is connected between the installation housing 1 and the water flow guiding block 8. Water enters the valve core through the lower end of the water flow guiding block 8 and then flows out through the side surface of the water flow guiding block 8. A supporting block 9 is also arranged between the water flow guiding block 8 and the inner surface of the installation housing 1. A third sealing ring 16 is connected between the water flow guiding block 8 and the moving rod 6. The third sealing ring 16 is located between the supporting block 9 and the water flow guiding block 8 at the same time, improving the overall sealing performance of the valve core. The lower end of the moving rod 6 sequentially passes through the supporting block 9 and the water flow guiding block 8 and is fixedly connected to a blocking block 7. A spring 10 is installed between the upper surface of the supporting block 9 and the moving block 3. The spring 10 is sleeved outside the moving rod 6.
[0022] Further, the groove body 5 includes four buffer grooves 11 and four valve closing grooves 12 arranged at equal intervals. The four buffer grooves 11 are all inclined. The four first supporting ribs 4 are in clearance fit with the four valve closing grooves 11 respectively, that is to say, the four first supporting ribs 4 can move in the valve closing grooves 11. The upper surfaces of the four first supporting ribs 4 are all inclined and are respectively adapted to the four buffer grooves 11. Four second supporting ribs 13 are arranged at equal intervals on the outer side of the pressing block 2. The four second supporting ribs 13 always move in the corresponding valve closing grooves 12. A ring-shaped tooth body is arranged on the lower surface of the pressing block 2. The ring-shaped tooth body is adapted to the upper surface of the first supporting rib 4. When the valve core is in the initial position, both the second supporting rib 13 and the first supporting rib 4 are located in the corresponding valve closing grooves 11, and at this time the valve core is in the closed state. When the pressing block 2 is pressed, the pressing block 2 moves downward, driving the moving block 3 and the first supporting rib 4 to move downward. When the first supporting rib 4 leaves the valve closing groove 12, the ring-shaped tooth body at the lower end of the pressing block 2 will drive the upper surface of the first supporting rib 4 to rotate a small angle. And when the first supporting rib 4 rotates a small angle at this time, it immediately enters the buffer groove 11 through the inclination of the corresponding buffer groove 11 for limiting. At this time, the moving block 3 is limited and moves downward by a certain distance relative to the initial position. Therefore, the moving rod 6 will also be driven to move downward during the downward movement. After the moving rod 6 moves downward, it drives the blocking block 7 to separate from the water flow guiding block 8. At this time, the valve core is in the open state, and water flows in through the lower end of the water flow guiding block 8 and then flows out through the side surface of the water flow guiding block 8.
[0023] Specifically, when in use, when the pressing block 2 is pressed for the first time and the valve core is in the initial closed position, both the second support rib 13 and the first support rib 4 are located in the corresponding valve closing grooves 11. When the pressing block 2 is pressed again, the pressing block 2 moves downward, driving the moving block 3 and the first support rib 4 to move downward. When the first support rib 4 leaves the valve closing groove 12, the annular tooth-shaped body at the lower end of the pressing block 2 drives the upper surface of the first support rib 4 to rotate a small angle. At this time, after the first support rib 4 rotates a small angle, it immediately enters the buffer groove 11 through the inclined shape of the corresponding buffer groove 11 for limiting. At this time, the moving block 3 is limited and moves downward by a certain distance relative to the initial position. Therefore, the moving rod 6 will also be driven to move downward during the downward movement. After the moving rod 6 moves downward, it drives the blocking block 7 to disengage from the water flow guiding block 8. At this time, the valve core is in the open state, and water flows in through the lower end of the water flow guiding block 8 and then flows out through the side surface of the water flow guiding block 8. Similarly, after the pressing block 2 is pressed again, under the action of the elastic force of the spring 10, the first support rib 4 returns to the valve closing groove 12, and the blocking block 7 blocks the water flow guiding block 8 to achieve valve core closing. This simple type of switch valve core can achieve rapid state switching after pressing. Through the design of multiple sealing rings, the sealing performance is improved, and there will be no water overflow or leakage. The valve core is small in size and can be used in small faucets or installed in different scenarios such as handles. This switch valve core has a simple structure, low cost and is suitable for a variety of operating environments.
[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
