Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of valve cores, and in particular to a switch valve core with controllable water outlet time. Background Art
[0002] The current purely mechanical valve design only allows users to adjust the water flow rate through the valve, but does not have the function of controlling the total amount of water flowing through the valve at one time when a single press is made. That is to say, when the water pressure is constant, the time for the water to flow out after a single press of the valve core cannot be adjusted. This means that such valves cannot meet the use standards in application scenarios that require accurate measurement or allocation of specific amounts of water. Although electronic valves provide a solution that allows users to set and control the total outflow of water, they are usually more expensive and must rely on an external power source to operate, which may not be the most ideal choice in some environments, especially in situations where the power supply is limited or cost-sensitive. Therefore, for users who need precise water control but are limited by their budget, the existing valve options may not fully meet their needs.
[0003] Therefore, a switch valve core with controllable water outlet time is provided to solve the above problems. Utility Model Content
[0004] The utility model provides a switch valve core with controllable water outlet time, which solves the problem that the water outlet time cannot be adjusted. In the scene where accurate measurement or distribution of a specific amount of water is required, this type of valve cannot meet the requirements, and if an electronic valve is used, it depends on the power source and has high cost.
[0005] The technical solution of the utility model is as follows: it comprises a valve core housing, characterized in that a pressing block is arranged at the upper end of the valve core housing, a fixed sealing guide portion is arranged inside the valve core housing, a return spring 1 is arranged between the upper surface of the sealing guide portion and the pressing block, a moving rod is movably connected inside the pressing block, a piston 1 is fixedly arranged at the lower end of the moving rod passing through the sealing guide portion, a moving block is connected to the outer side of the piston 1, a return spring 2 is arranged between the upper surface of the moving block and the sealing guide portion, and a sealing block is fixedly arranged at the lower end of the moving block;
[0006] A water flow guide block is fixedly arranged on the lower surface of the sealing guide portion, and a fixing block is fixedly arranged on the lower end of the water flow guide block;
[0007] A water outlet is provided in the middle of the fixed block, the sealing block can be abutted against and connected to the upper surface of the water outlet, and a water inlet assembly is fixedly provided at the lower end of the valve core housing;
[0008] A threaded hole is provided inside the pressing block, and the pressing block is threadedly connected with a top screw through the threaded hole.
[0009] As a preferred technical solution of the utility model, the water inlet assembly includes a water inlet shell having a plurality of openings equidistantly arranged on the outer surface, a piston 2 is movably connected to the inner side of the water inlet shell, and a return spring 3 is provided between the upper surface of the piston 2 and the water flow guide block.
[0010] As a preferred technical solution of the utility model, a rectangular opening 1 for water to pass through is provided on the water inlet housing.
[0011] As a preferred technical solution of the utility model, the inner side wall of the moving block is provided with a second rectangular opening for water to pass through.
[0012] As a preferred technical solution of the utility model, two water inlets are provided at the lower end of the water flow guide block.
[0013] As a preferred technical solution of the utility model, the depth of the moving block is greater than the depth of the internal threaded hole of the pressing block.
[0014] The working principle and beneficial effects of the utility model are:
[0015] When the utility model is in use, the valve core is in a closed state, the sealing block is against the water outlet, the height of the top screw is adjusted, and then the pressing block is pressed, the top screw will support the upper end of the moving rod and drive it to move downward, so that the lower end of the moving rod will also drive the piston to reach a low point inside the moving block. If the pressing block is pressed continuously, the valve core will be in a closed state all the time. At the moment of releasing the pressing block, the pressing block is reset by the reset spring, the pressure applied by the top screw to the upper end of the moving rod disappears, the moving rod and the moving block are in a weightless state, and because the water pressure outside the moving block is greater than the water pressure inside the moving block, the moving block will move up quickly, thereby driving the sealing block to move up, and the water outlet is opened at this time, and the valve core is in an open state. State, after a period of time, due to the action of the reset spring 2, the moving block starts to move downward again, and the piston 2 will also be reset under the action of the reset spring 3. At the same time, the water flow continues to flow into the moving block. When the sealing block at the lower end of the moving block hits the water outlet again, the internal and external pressure difference of the moving block reaches equilibrium again. At this time, the valve core is in a closed state again. When the top screw is turned clockwise, the water outlet time will be increased; conversely, when the top screw is turned counterclockwise, the water outlet time will be reduced. Therefore, the valve core realizes the function of controlling the total amount of water flowing through the valve at a time when a single press is performed through a simple mechanical structure. The water outlet time of the valve core can be adjusted by adjusting the height of the top screw. The valve core can be used in application scenarios for accurately measuring or distributing a specific amount of water to set and control the water outlet time, save water, and has low cost and simple operation.

DETAILED DESCRIPTION
[0022] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example
[0024] like Figure 1-4As shown, the present embodiment proposes a switch valve core with controllable water outlet time, comprising a valve core housing 1, a pressing block 2 is arranged at the upper end of the valve core housing 1, a fixed sealing guide part 3 is arranged inside the valve core housing 1, a return spring 4 is arranged between the upper surface of the sealing guide part 3 and the pressing block 2, and the pressing block 2 can be reset by the return spring 4 after being pressed, a threaded hole is arranged inside the pressing block 2, and the pressing block 2 is threadedly connected with a top screw 18 through the threaded hole, and its height position inside the pressing block 2 can be adjusted by rotating the top screw 18 clockwise or counterclockwise, so as to control the movable stroke of the moving rod 5, and the moving rod 5 is movably connected inside the pressing block 2, and when the moving rod 5 is located at the bottom of the pressing block 2, the upward movement of the pressing block 2 will also drive the moving rod 5 to move upward, and the lower end of the moving rod 5 passes through the sealing guide part 3 and is fixedly provided with a piston 1 6. A moving block 7 is connected to the outer side of the piston 6, that is to say, the movement of the moving rod 5 will simultaneously drive the movement of the piston 6 and the moving block 7. The depth of the moving block 7 is greater than the depth of the internal threaded hole of the pressing block 2. This is to limit the piston 6 on the inner side of the moving block 7. A return spring 2 12 is provided between the upper surface of the moving block 7 and the sealing guide part 3. A sealing block 8 is fixedly provided at the lower end of the moving block 7. A water flow guide block 9 is fixedly provided on the lower surface of the sealing guide part 3. A fixed block 10 is fixedly provided at the lower end of the water flow guide block 9. A water outlet 11 is provided in the middle of the fixed block 10. The water entering the valve core is discharged through the water outlet 11, and the sealing block 8 can resist the upper surface connected to the water outlet 11, that is to say, the sealing block 8 can control whether the water outlet 11 discharges water. A water inlet assembly 13 is fixedly provided at the lower end of the valve core housing 1.
[0025] Furthermore, the water inlet assembly 13 includes a water inlet shell 14 having a plurality of openings equidistantly arranged on the outer surface, a piston 2 15 is movably connected to the inner side of the water inlet shell 14, a return spring 3 16 is provided between the upper surface of the piston 2 15 and the water flow guide block 9, a rectangular opening 17 for water to pass through is provided on the water inlet shell 14, a rectangular opening 2 19 for water to pass through is provided on the inner wall of the movable block 7, and two water inlets are provided at the lower end of the water flow guide block 9, and the water flows into the valve core through the rectangular opening 17 and the rectangular opening 2 19 in turn.
[0026] When the utility model is in use, the valve core is in a closed state, and water flows through the water inlet housing 14 into the rectangular opening 17 and the rectangular opening 2 19 in turn, and finally fills the entire lower end of the sealing guide portion 3. Therefore, the water pressure inside the valve core pushes the piston 2 15 to move to the lowest point. At this time, the sealing block 8 is against the water outlet 11, and the height of the top screw 18 is adjusted. Then, the pressing block 2 is pressed, and the top screw 18 will support the upper end of the moving rod 5 and drive it to move downward, so that the lower end of the moving rod 5 will also drive the piston 1 6 to reach a low point on the inner side of the moving block 7. If the pressing block 2 is pressed continuously, the valve core will be in a closed state all the time, and the piston 1 6 will also remain at this low point. At the moment of releasing the pressing block 2, the pressing block 2 is reset by the reset spring 1 4, and the top screw 18 will be pressed. The pressure applied by the wire 18 to the upper end of the moving rod 5 disappears, and the moving rod 5 and the moving block 7 are in a weightless state. Since the water pressure outside the moving block 7 is greater than the water pressure inside it, the moving block 7 will move up quickly, thereby driving the sealing block 8 to move up. At this time, the water outlet 11 is opened, the valve core is in an open state, and water flows out quickly. At this time, the water flow will drive the piston 2 15 to move up. After a period of time, the moving block 7 starts to move downward again under the action of the reset spring 2 12, and the piston 2 15 will also be reset under the action of the reset spring 3 16. At the same time, the water flow also continuously flows into the moving block 7. When the sealing block 8 at the lower end of the moving block 7 hits the water outlet 11 again, the internal and external pressure difference of the moving block 7 reaches equilibrium again, and the valve core is in a closed state again.
[0027] When the top screw 18 is rotated clockwise, the top screw 18 moves downward inside the pressing block 2, that is, the downward movement of the top screw will reduce the activity height of the moving rod 5 in the pressing block 2, and the upper limit of the movement of the moving rod 5 will be reduced. Because the top screw 18 moves downward, the upper limit of the movement of the moving rod 5 will be reduced. Therefore, after pressing the pressing block 2, the lower end of the moving rod 5 will move to a lower height, so the moving rod 5 will drive the piston 16 to move to a lower height inside the moving block 7. According to the above working principle, since the piston 16 moves to a lower height inside the moving block 7, the reset distance of the moving block 7 will also increase at the same time, so the reset time will also increase. Therefore, when the top screw 18 is rotated clockwise, the water discharge time will be increased;
[0028] On the contrary, when the top screw 18 is rotated counterclockwise, it moves upward inside the pressing block 2, that is to say, the upward movement of the top screw will increase the activity height of the moving rod 5, and the upper limit of the movement of the moving rod 5 will increase. Therefore, after pressing the pressing block 2, the lower end of the moving rod 5 will only move downward a small distance, so the moving rod 5 will drive the piston 6 to move downward a small distance. According to the above working principle, since the piston 6 moves downward a small distance, the reset distance of the moving block 7 will also be smaller, so the reset time will also be reduced. Therefore, when the top screw 18 is rotated counterclockwise, the water outlet time will be reduced.
[0029] Therefore, the valve core realizes the function of controlling the total amount of water flowing through the valve at one time when a single press is performed through a simple mechanical structure. That is to say, under the condition of constant water pressure, the time of water discharge from the valve core can be adjusted by adjusting the height of the top screw 18 when the valve core is pressed once. The valve core can be used in application scenarios for accurately measuring or distributing a specific amount of water, such as in the faucet of a public toilet wash basin. By using the valve core, water can be saved by adjusting the best hand washing time. When a person presses the pressing block 2, no water will be discharged. Only when the user releases his hand will water be discharged, so as to achieve the purpose of saving water and save costs. For another example, when the toilet in a public toilet uses this valve core, a person sits on the toilet (or steps on it), which is equivalent to pressing on the pressing block 2. When the person wants to leave, he will release the pressing block 2, and the purpose of automatic flushing is achieved. Of course, the time of this flushing can also be adjusted. The valve core allows users to set and control the total outflow of water, and it is low in cost and simple to operate.
[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
