Detailed Description

The embodiment of the invention provides an external time delay faucet, which comprises a faucet body 1, a time delay device 2, a first gear 11, a rotating assembly, a water outlet tank 25 and a reset mechanism, as shown in figures 1-8. The tap body 1 is in threaded connection with the time delay device 2. The first gear 11 is fixedly welded with the handle of the faucet body 1. When the faucet is in operation, the first gear 11 can be rotated by rotating the faucet handle. The water inlet end of the tap body 1 is screwed into the water outlet end of the time delay device 2 through threads. The time delay device 2 is internally provided with a water inlet cavity 21 and a water outlet cavity 22 respectively. The outlet tank 25 is located in the outlet chamber 22. The outlet tank 25 receives water from the inlet chamber 21. The outlet tank 25 can slide up and down. A groove 23 is arranged above the water outlet cavity 22, and the rotating component is arranged in the groove 23. The lower end of the rotating component is connected with the water outlet tank 25, the rotating component is matched with the handle of the faucet body 1 through the first gear 11, and the rotating component can drive the water outlet tank 25 to move up and down. When the faucet is in operation, the faucet handle is rotated, the first gear 11 is rotated, and the first gear 11 drives the rotating assembly to rotate. When the water outlet tank 25 moves to the highest position, the water outlet of the device 2 is closed. When the water outlet tank 25 moves to the lowest position, the water outlet of the time delay device 2 is opened. The reset mechanism is arranged in the groove 23 and is connected with the rotating component, and the water inlet of the water outlet tank 25 is communicated with the water inlet cavity 21. The rotating component is matched with the reset mechanism. The water outlet tank 25 is lowered and then returns to the original position after a certain time, so as to achieve the effect of time delay. When the water faucet works, the rotating component rotates to drive the water outlet tank 25 to descend, and the water faucet discharges water. And then, the rotating assembly is slowly rotated by utilizing the reset mechanism, so that the water outlet tank 25 of the passage slowly rises, and the water tap is closed after the water outlet tank 25 returns to the original position.

The rotating assembly comprises a second gear 24, a third gear 3, a screw rod 4 and a ball 5. The second gear 24 is pivoted on the time delay device 2. Gear three 3 is disposed within recess 23. The screw rod 4 is arranged at the axis of the gear 3. The upper end of the screw rod 4 penetrates through the gear III 3 to be pivoted with the top of the inner wall of the groove 23, and the gear III 3 is fixedly welded with the surface of the screw rod 4. Gear three 3 meshes with gear two 24, and gear two 24 meshes with gear one 11. Through intermeshing between the gear for the book tap handle can drive lead screw 4 to rotate when rotating, and lead screw 4 rotates simultaneously also can make the handle rotatory. When the handle is rotated by a hand, the first gear 11 drives the second gear 24 to rotate, the second gear 24 drives the third gear 3 to rotate, and the third gear 3 drives the screw rod to rotate. The lower end of the screw rod 4 extends into the water outlet tank 25, and the ball 5 is positioned in the water outlet tank 25. The ball 5 is in sliding fit with the screw rod 4, and the ball 5 and the screw rod 4 form a ball screw rod. The body of the screw rod 4 is provided with threads, and when the screw rod 4 rotates, the ball 5 can be driven to move. Since this is the prior art, it is a conventional technical means, and the specific sliding fit manner of the screw 4 and the ball 5 is the same as that of the conventional technical means, and will not be described in detail. One side of the ball 5 is welded with the inner wall of the water outlet tank 25. One side of the ball 5 is fixedly connected with the water outlet tank 25, so that the ball 5 can drive the water outlet tank 25 to move up and down in the up-and-down moving process. The surface of the screw rod 4 is connected with a resetting mechanism. The screw rod 4 can rotate back to the original position when rotating along with the handle by utilizing the reset mechanism. When the water outlet box is in work, the handle rotates to drive the screw rod 4 to rotate, so that the ball 5 descends, the water outlet box 25 moves downwards, then the handle is released to hold the handle, and the reset mechanism slowly rotates the screw rod 4 in the opposite direction. When the screw rod 4 is completely rotated back to the original position, the water outlet tank 25 is moved up to the original position.

The water outlet of the water outlet tank 25 is blocked.

The reset mechanism comprises a scroll track 6, a scroll spring 7, a plurality of elastic small blocks 8 and small bulges 9. The scroll track 6 is fixedly welded with the bottom of the inner wall of the groove 23. The scroll spring 7 is positioned in the scroll track 6, and the outer end of the scroll spring 7 is fixedly welded with the inner wall of the groove 23. The inner end of the scroll spring 7 is fixedly welded with the surface of the screw rod 4. After the screw rod 4 is rotated through the volute spiral spring 7, the screw rod 4 is pulled back to the original position, and the reset effect is achieved. When the screw rod works, the screw rod 4 rotates to pull the scroll spring 7 to be slowly contracted, so that the scroll spring 7 generates a reset reaction force. When the handle of the water faucet is loosened by hand, the volute spiral spring 7 returns to the original shape, and the inner end of the volute spiral spring 7 pulls the screw rod 4 to rotate back to the original position.

The elastic small blocks 8 are fixedly adhered along the inner wall of the scroll track 6 at equal intervals. The small bulge 9 is welded with the middle part of the spiral spring 7, and the small bulge 9 can be in surface contact with the small elastic block 8. Through the contact friction of the small bulge 9 and the surface of the small elastic block 8, the restoring speed of the volute spiral spring 7 is delayed, and the small elastic block 8 has certain elasticity, so that when the small bulge 9 passes through the small elastic block 8, the small bulge 9 cannot be clamped, and the screw rod 4 needs a certain time to be rotated back to the original position, thereby achieving the time-delay effect. When the scroll spring works, the scroll spring 7 is continuously contracted, the small bulge 9 passes through the small elastic blocks 8, and the small elastic blocks 8 are extruded and deformed, so that the small bulge 9 moves between the small elastic blocks 8 behind. When the spiral spring 7 starts to restore to the original state, the small protrusion 9 is firstly obstructed by the small elastic block 8 and then continuously moves through the small elastic block 8 under the action of the elastic force until the spiral spring 7 restores to the original state.

In the case of a non-rotated handle, the spiral spring 7 is in a slightly tensioned state, so that the spiral spring 7 always has a force pulling the screw 4. When the water tap is not used, the spiral spring 7 always pulls the screw rod 4, so that the screw rod 4 keeps a state of moving the water outlet tank 25 to the highest position. The function of avoiding water leakage is achieved.

This external time delay tap sets up time delay device 2 in the tap outside, becomes assembled, convenient to detach change with tap. The integrated faucet delay assembly is prevented from being damaged and then being discarded integrally to cause waste. The faucet handle is matched with the screw rod 4 through a plurality of gears, so that the handle and the screw rod 4 synchronously rotate, the water outlet tank 25 is controlled to move up and down under the matching of the screw rod 4 and the ball 5, and the purpose of controlling the faucet to discharge water is achieved. Under the matching of the scroll spring 7, the small elastic block 8 and the small bulge 9, the screw rod 4 can slowly rotate to achieve the effect of time delay.

The water inlet cavity 21 is internally provided with a U-shaped pipe 26, and the U-shaped pipe 26 is placed in an inverted manner. The U-shaped pipe 26 is fixedly welded with the inner wall of the water inlet cavity 21. The water inlet end of the U-shaped pipe 26 is vertically downward, the appearance end of the U-shaped pipe 26 is vertically downward, and the water outlet end of the U-shaped pipe 26 extends into the water outlet tank 25. The water inlet end of the U-shaped pipe 27 is higher than the water outlet end, water continuously enters the water inlet cavity 21, and water in the water inlet cavity 21 can slowly enter the U-shaped pipe 27 when the water enters the U-shaped pipe 27

When the liquid level in the water inlet cavity 21 is flush with the rear part of the U-shaped pipe 26, the water in the U-shaped pipe 26 flows to the water outlet end of the U-shaped pipe and is discharged into the water outlet tank 25 from the water outlet end. When the liquid level of the water inlet cavity 21 exceeds the U-shaped pipe 27, a siphon effect is formed because the water inlet end of the U-shaped pipe is higher than the water outlet end of the U-shaped pipe. At this time, even if water does not flow into the inlet chamber 21, the water in the inlet chamber 21 is discharged into the outlet tank 25 by a siphon effect.

The delay device 2 further comprises a connecting tube 27, one end of the connecting tube 27 is communicated with the water inlet chamber 21, and the other end of the connecting tube 28 is communicated with the water outlet chamber 22. The inlet chamber 21 is communicated with the external pressure through the connecting pipe 27, so that the inlet chamber 21 is prevented from being closed and the siphon effect cannot be formed.

The working principle is as follows: when the water-saving water faucet is used, a handle on the water faucet 1 is rotated by hand, water flows into the water inlet cavity 21 of the time delay device 2 from a pipeline, the liquid level in the water inlet cavity 21 is continuously increased along with the continuous injection of the water, and the water is discharged into the water outlet tank 25 through the U-shaped pipe 26. Meanwhile, the handle drives the first gear 11 to rotate, the first gear 11 drives the second gear 24 to rotate, the second gear 24 drives the third gear 3 to rotate, the third gear drives the screw rod 4 to rotate, the screw rod enables the balls 5 to slide downwards to drive the water outlet tank 25 to descend, and the volute spiral spring 7 rotates along with the screw rod 4 to contract. After the hands are released, the volute spiral spring 7 starts to restore, the screw rod 4 is slowly made to rotate reversely under the matching of the small bulge 9 and the small elastic block 8, the water outlet tank 25 is slowly driven to ascend when the screw rod 4 rotates reversely until the screw rod 4 returns to the original position, the water outlet tank 25 moves to the highest position, the faucet is closed, and the handle 11 returns to the original position.

To sum up, this external time delay tap sets up time delay unit 2 in the tap outside, becomes assembled, convenient to detach change with tap. The integrated faucet delay assembly is prevented from being damaged and then being discarded integrally to cause waste. The faucet handle is matched with the screw rod 4 through a plurality of gears, so that the handle and the screw rod 4 synchronously rotate, the water outlet tank 25 is controlled to move up and down under the matching of the screw rod 4 and the ball 5, and the purpose of controlling the faucet to discharge water is achieved. Under the matching of the scroll spring 7, the small elastic block 8 and the small bulge 9, the screw rod 4 can slowly rotate to achieve the effect of time delay.
