Description

Technical Field

[0001] The utility model relates to the technical field of water saving, in particular to a water saving control device. Background Art

[0002] Faucet is the popular name of water valve, which is used to control the size of water flow and has the effect of saving water. The replacement speed of faucets is very fast. Now more and more consumers buy faucets and consider them comprehensively from many aspects such as material, function, shape, and high efficiency and water saving.

[0003] Chinese patent announcement number CN220928044U discloses a water-saving control device, which includes a water pipe and a control box. The water pipe is connected to the inside of the control box. The surface of the water pipe is connected to a water flow sensor. The surface of the water pipe is connected to a solenoid valve located on the top of the water flow sensor. The right side of the inner wall of the control box is connected with an infrared sensor. By setting the water flow sensor and the solenoid valve, it is convenient for the user to adjust the water flow sensor through the controller. When the adjusted water flow is reached, the controller cuts off the power to the solenoid valve to avoid water outflow, solving the current problem of opening the water source when using the water source. The valve does not have the function of controlling the metering use of the water source, resulting in endless discharge of water when the user is busy with other things during the process of collecting water. The water source continues to discharge even when it overflows the water collecting container, thereby causing water waste. In order to achieve the effect of controlling water discharge, the above technology realizes the function of metering the use of water source through the cooperation of a controller, a water flow sensor and a solenoid valve, but the intelligent control method is highly dependent on electricity and is not suitable for large-scale promotion. In addition, the failure rate of electrical components is high, and there is a risk of leakage. For this reason, the utility model discloses a water-saving control device for solving the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model relates to a water-saving control device. When a button is pressed, the button pushes the center rod downward, driving the differential damping plate downward.

[0014] 2. The utility model provides a water-saving control device. When the button is pressed, the first damping hole is larger in size, which results in less resistance to the user's pressing and effortless operation. Under the elastic force of the spring, when the differential damping plate moves up and resets, the second damping hole is smaller in size, resulting in lower efficiency of the damping oil passing through. This causes the speed of the rack meshing transmission gear to rotate in the opposite direction to slow down, and the time for the valve stem to drive the intercepting plate to block the water flow is greatly extended. The user can use water in this neutral position without frequent operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the embodiments.

[0025] See also Figure 1-6 The utility model provides a water-saving control device, comprising a water supply pipe 1, a valve pipe 2 is fixedly sleeved on the top of the water supply pipe 1, and a water outlet pipe 3 is fixedly embedded on the upper side of the valve pipe 2;

[0026] Specifically, the water supply pipe 1 is connected to the tap water pipe to provide water pressure, and the water outlet pipe 3 is an elbow structure, which can guide the water to flow downward, making it convenient for users to use.

[0027] Furthermore, a valve blade 4 that can be opened and closed is provided in the valve pipe 2. The valve blade 4 includes a valve sleeve 41 located in the cylindrical cavity of the valve pipe 2. A valve stem 42 is fixedly sleeved in the middle of the valve sleeve 41. Both sides of the valve sleeve 41 are fixedly connected to a shutoff plate 43. The valve stem 42 is rotatably connected between the end faces of the valve pipe 2, and one end of the valve stem 42 extends into the control box 5. A first baffle 21 and a second baffle 22 are respectively fixed on the inner walls of both sides of the valve pipe 2. The first baffle 21 and the second baffle 22 can be respectively fitted with the two shutoff plates 43.

[0028] Specifically, the fit between the first baffle 21 and the second baffle 22 and the intercepting plate 43 helps to improve the sealing performance of the valve and prevent water from leaking from the gap when the valve is closed. It is worth noting that the outer side of the intercepting plate 43 is provided with a rubber sealing sleeve to enhance the anti-leakage ability.

[0029] Furthermore, a control box 5 is installed at one end of the valve tube 2, and a valve control assembly 6 is installed on the control box 5. The valve control assembly 6 maintains a transmission connection with the valve blade 4 to limit the opening time of the valve blade 4. The valve control assembly 6 includes a sealing chamber 61 fixed on the upper side of the control box 5, and the sealing chamber 61 is filled with damping oil. A differential damping plate 62 is slidably connected to the sealing chamber 61, and a center rod 63 is fixedly sleeved in the middle of the differential damping plate 62. The top of the center rod 63 passes through the sealing chamber 61 and is fixedly connected to a button 64. The bottom end of the center rod 63 extends into the control box 5, and the outside of the center rod 63 is located between the differential damping plate 62 and the sealing chamber 61, a spring 65 is sleeved between the bottom walls, the differential damping plate 62 is provided with a first damping hole 621 and a second damping hole 622, the upper opening of the first damping hole 621 and the lower opening of the second damping hole 622 are both provided with a sealing groove 623, one side of the sealing groove 623 is provided with a notch, and a rotating shaft 624 is rotatably connected between the inner walls on both sides of the notch, the outer side of the rotating shaft 624 is fixedly sleeved with a valve plate 625 that is compatible with the structure of the sealing groove 623, the outer side of the rotating shaft 624 and between the valve plate 625 and the notch are sleeved with a torsion spring 626, the two free ends of the torsion spring 626 are respectively fixedly connected to the adjacent valve plate 625 and the notch wall;

[0030] Specifically, the sliding of the differential damping plate 62 in the sealed chamber 61 is affected by the damping oil. Press the button 64, and the button 64 pushes the center rod 63 downward, driving the differential damping plate 62 downward. Under the action of the upper and lower pressure difference of the differential damping plate 62, the valve plate 625 opposite the first damping hole 621 is opened, and the differential damping plate 62 can move downward smoothly. Conversely, release the button 64, and under the elastic force of the spring 65, the differential damping plate 62 moves upward. Under the action of the upper and lower pressure difference of the differential damping plate 62, the valve plate 625 opposite the second damping hole 622 is opened, and the differential damping plate 62 can move upward smoothly.

[0031] Furthermore, the first damping hole 621 and the second damping hole 622 are both arranged in a circular structure, and the diameter of the first damping hole 621 is larger than the diameter of the second damping hole 622;

[0032] Specifically, the diameters of the first damping hole 621 and the second damping hole 622 are different, which affects the speed at which the differential damping plate 62 moves up and down in the control box 5. The diameter of the first damping hole 621 is larger, so that the differential damping plate 62 moves down faster when the user presses the button 64, while the diameter of the second damping hole 622 is smaller, resulting in the differential damping plate 62 moving up slower under the elastic force of the spring 65. After releasing the button 64, the upward movement speed of the differential damping plate 62 slows down, thereby extending the opening time of the valve blade 4. The user can use water during this period without frequently operating the button 64, reducing the waste of water resources caused by forgetting to turn off the faucet or inadequate closing. It is worth noting that the size of the second damping hole 622 can determine the length of time the valve blade 4 is open.

[0033] Furthermore, a rectangular frame 66 is fixed to one end of the center rod 63 located in the control box 5, and a rack 67 is fixed to the inner wall of one side of the rectangular frame 66. The rack 67 is meshed with a gear 68, and the gear 68 is fixed to the end of the valve stem 42 located in the control box 5;

[0034] Specifically, the differential damping plate 62 moves downward, the rack 67 engages the transmission gear 68 to rotate, the gear 68 drives the valve stem 42 to rotate, and the valve stem 42 drives the intercepting plate 43 to switch to a state consistent with the direction of water flow, so that tap water can flow out smoothly. Conversely, the differential damping plate 62 moves upward, the rack 67 engages the transmission gear 68 to rotate in the opposite direction, and the valve stem 42 can drive the intercepting plate 43 to block the water flow.

[0035] Working principle:

[0036] When in use, the water supply pipe 1 is connected to the tap water pipe. When the user uses water, he presses the button 64, and the button 64 pushes the center rod 63 downward, driving the differential damping plate 62 downward. Under the action of the upper and lower pressure difference of the differential damping plate 62, the valve plate 625 opposite to the first damping hole 621 is opened, so that the differential damping plate 62 can move downward smoothly, the rack 67 engages the transmission gear 68 to rotate, and the gear 68 drives the valve stem 42 to rotate. The valve stem 42 drives the intercepting plate 43 to switch to a state consistent with the water flow direction, so that the tap water can flow out smoothly. Afterwards, under the elastic force of the spring 65 , the differential damping plate 62 moves upward. Under the action of the upper and lower pressure difference of the differential damping plate 62, the valve plate 625 opposite the second damping hole 622 is opened, so that the differential damping plate 62 can move upward smoothly. Since the flow rate of the second damping hole 622 is small, the upward movement speed of the differential damping plate 62 is extremely low, which in turn causes the rack 67 to engage with the transmission gear 68 to rotate in the opposite direction and slow down. The time that the valve stem 42 drives the intercepting plate 43 to block the water flow is greatly extended, and the user can use water in this neutral position, avoiding the waste of water resources caused by forgetting to turn off the faucet or incompletely closing it.
