Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a faucet. Background Technology

[0002] For example, a bottom-opening flushing faucet with announcement number "CN201661756U" has a handle connected to the bottom of the faucet that can swing up and down. This faucet makes it easy to rinse the handle, has a simple structure, and is worth promoting. However, the above-mentioned faucet lacks a mechanical delayed-closing function. After the faucet is turned on, the user needs to manually turn it off, which is cumbersome and requires pressing the handle multiple times. This is especially inconvenient when both hands are occupied (such as when carrying a basin or holding a child), resulting in low practicality. In addition, if the user forgets to turn off the faucet after turning it on, water will be continuously wasted. Summary of the Invention

[0003] The purpose of this utility model is to solve the problem of faucets that lack mechanical delayed shut-off performance, requiring manual shut-off after being turned on, which is cumbersome and requires pressing the handle multiple times. This is especially inconvenient when both hands are occupied (such as when carrying a basin or holding a child), resulting in low practicality. Furthermore, if the user forgets to turn off the faucet after turning it on, it will lead to continuous water waste. Therefore, this utility model proposes a new type of faucet.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] Design a faucet including a pipe and a valve plate, wherein the inner wall of the pipe is fixedly connected to the valve plate, the inner wall of the valve plate is fitted with a ball valve, a handle is fixedly connected to the right side of the ball valve, and a delayed closing structure is provided in the middle of the outer wall of the pipe.

[0006] Preferably, the delayed closing structure includes a housing, the right side of the inner wall of the housing is rotatably connected to a first gear via a sealed bearing, the outer wall of the first gear is meshed with a second gear, the rotating shaft of the second gear is rotatably connected to the housing via a bearing, a torsion spring is provided at the left end of the rotating shaft of the second gear, the two ends of the torsion spring are fixedly connected to the housing and the second gear respectively, the upper end of the housing is fixedly connected to the liquid inlet, and the upper end of the liquid inlet is threadedly connected to the top cover.

[0007] Preferably, the end of the first gear rotating shaft is fixedly connected to the ball valve.

[0008] Preferably, the right side of the outer wall of the outer casing is fixedly connected to the pipe.

[0009] Preferably, the outer wall of the handle is rotatably connected to the pipe via a sealed bearing.

[0010] The faucet proposed in this utility model has the following advantages: Through a delayed-closing structure, the torsion spring rebounds and drives the second gear to reverse, which in turn drives the first gear to reverse. However, due to the gear ratio between the second and first gears, the ball valve slowly reverses and closes because of the damping effect of the silicone oil on the first and second gears. The torsion spring drives the second and first gears to rotate, and the reduced gear ratio between the second and first gears, combined with the damping effect of the silicone oil on the first and second gears, allows the ball valve and handle to slowly return to their original positions. This reduces the steps required for users to close the faucet when their hands are occupied, effectively improving practicality. At the same time, it can automatically close the faucet if the user forgets to turn it off, preventing continuous water waste. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-6 In this embodiment, a faucet includes a pipe 2 and a valve plate 4. The inner wall of the pipe 2 is fixedly connected to the valve plate 4, and the inner wall of the valve plate 4 is in contact with the ball valve 3. The valve plate 4 can ensure the relative sealing between the ball valve 3 and the pipe 2. A handle 5 is fixedly connected to the right side of the ball valve 3, and a delayed closing structure 1 is provided in the middle of the outer wall of the pipe 2.

[0020] The end of the rotating shaft of the first gear 104 is fixedly connected to the ball valve 3, the right side of the outer wall of the outer shell 101 is fixedly connected to the pipe 2, and the outer wall of the handle 5 is rotatably connected to the pipe 2 through a sealed bearing, so that the handle 5 can rotate inside the pipe 2 through the sealed bearing.

[0021] See attached document Figure 1-4 The delayed closing structure 1 includes a housing 101. The right side of the inner wall of the housing 101 is rotatably connected to the first gear 104 through a sealed bearing. The first gear 104 can rotate inside the housing 101 through the sealed bearing. The outer wall of the first gear 104 is meshed with the second gear 103. The rotating shaft of the second gear 103 is rotatably connected to the housing 101 through a bearing.

[0022] The second gear 103 can rotate within the housing 101 via a bearing. A torsion spring 102 is provided at the left end of the rotating shaft of the second gear 103. The elastic coefficient of the torsion spring 102 is determined according to actual needs and can meet the working requirements. The two ends of the torsion spring 102 are fixedly connected to the housing 101 and the second gear 103 respectively. The upper end of the housing 101 is fixedly connected to the liquid inlet 105, and the upper end of the liquid inlet 105 is threadedly connected to the top cover.

[0023] Working principle:

[0024] Delayed faucet shut-off operation:

[0025] When the faucet needs to be used, the faucet consists of pipe 2, valve plate 4, ball valve 3, and handle 5. First, turn the top cover on the inlet 105 outward to remove it, then fill the inner cavity of the right end of the outer shell 101 with silicone oil and turn the top cover back.

[0026] During use, turn handle 5 upwards. Handle 5 rotates inside pipe 2 through the sealed bearing, which in turn drives ball valve 3 to rotate upwards inside valve plate 3. When handle 5 is in the vertical position, the through hole of ball valve 3 is in the open water outlet state inside pipe 2. Turning handle 5 in the opposite direction horizontally can make the through hole in the middle of ball valve 3 abut against valve plate 4, thus blocking pipe 2.

[0027] When the ball valve 3 rotates upward, it drives the first gear 104 to rotate within the housing 101 via a sealed bearing. In turn, the first gear 104 drives the second gear 103 to rotate within the housing 101 via a bearing. The first gear 104 has 100 teeth and the second gear 103 has 50 teeth. One rotation of the first gear 104 will drive the second gear 103 to rotate twice, thus forming a gear ratio. The rotation of the second gear 103 will compress the torsion spring 102. When the user releases the handle, the torsion spring 102 rebounds, causing the second gear 103 to reverse, which in turn drives the first gear 104 to reverse.

[0028] However, due to the gear ratio reduction between the second gear 103 and the first gear 104, and the damping effect of the silicone oil on the first gear 104 and the second gear 103, the ball valve 3 slowly reverses and closes. The silicone oil in the inner cavity of the right end of the housing 101 has a certain viscous resistance to slow down the rotation speed of the first gear 104 and the second gear 103. The delay time can be controlled by adjusting the viscosity of the silicone oil (e.g., thin oil closes quickly, thick oil closes slowly). At the same time, the torsion spring 102 with an appropriate elastic coefficient can be selected to adjust the reverse speed of the first gear 104 and the second gear 103. This movement can reset the ball valve 3 and the handle 5, delaying the faucet's closure. In addition, after the user finishes using the faucet, they can also manually reset the handle 5 to close it, thereby releasing the energy of the torsion spring 102 without delaying the closure.

[0029] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
