Description

Technical Field

[0001] The invention relates to the field of faucet technology, specifically a self-resetting faucet. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water and thus save water. Faucets are constantly being updated and replaced, evolving from old-fashioned cast iron faucets to electroplated knob faucets, and then to stainless steel single-temperature single-control faucets, stainless steel dual-temperature dual-control faucets, and semi-automatic kitchen faucets. Currently, there are various ways to open faucets, with push-button and knob being the most common.

[0003] In the prior art, self-resetting faucets are designed to save water in order to prevent users from forgetting to turn off the tap. However, the biggest inconvenience of such faucets is that the action must be quick when cleaning, otherwise the tap must be pressed repeatedly. They cannot adjust the water flow time according to the user's usage. Therefore, we propose a self-resetting faucet to solve this problem. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a self-resetting faucet.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution: a self-resetting faucet, comprising a stem and a pressure cap, wherein a connecting rod is fixedly installed at the upper end of the stem, and a pressure cap is provided on the connecting rod; a rotating ring is fixedly sleeved on the side wall of the connecting rod, and the rotating ring is disposed inside the pressure cap; a support plate is symmetrically installed on the lower side wall of the rotating ring inside the pressure cap, and the support plate slides against the lower side of the rotating ring; an arc-shaped block is fixedly installed on the outer side wall of the stem, and an arc-shaped groove is formed on the upper end face of the arc-shaped block; sliding air holes are symmetrically formed on the bottom walls on both sides of the bottom end of the arc-shaped groove; each of the two sliding air holes is provided with a vent hole; one of the vent holes is provided with an airflow limiting mechanism, and a micro air return hole is formed on the arc-shaped block located on one side of the airflow limiting mechanism; an L-shaped rod is fixedly installed on the outer side wall of the pressure cap, and a piston plate is rotatably installed on one end of the L-shaped rod, and the piston plate is slidably disposed in the arc-shaped groove.

[0006] Preferably, the limiting device includes a placement groove, which is formed on the surface of the rod body. A vertical rod is disposed in the placement groove. A support block is fixedly connected to the inner wall of the placement groove. A movable groove is formed on the surface of the rod body. A compression spring is fixedly connected to the inner wall of the movable groove. A push block is fixedly connected to the upper end of the compression spring. A push plate is fixedly connected to the side wall of the push block. The bottom end of the vertical rod penetrates the upper surface of the support block and extends into the movable groove, where it is fixedly connected to the push block. A hollow limiting rod is placed in the placement groove and is fixedly connected to the inner wall of the arc-shaped block.

[0007] Preferably, the upper sidewall of the pressure cap is provided with a pointer, the pointer is arranged in an arc shape, and both ends of the pointer are provided with pointing arrows.

[0008] Preferably, the airflow limiting mechanism includes a vent pipe, which is fixedly inserted into a vent hole, and a limiting rod is fixedly installed on the inner side wall of the vent pipe. A spring telescopic rod is fixedly installed on the side wall of the limiting rod, and an airflow blocking plate is fixedly installed at one end of the spring telescopic rod.

[0009] Preferably, limit blocks are symmetrically installed on both sides of the inner side of the arc-shaped groove, and the two limit blocks are respectively located on one side of the two sliding air holes.

[0010] Preferably, a torsion spring is fixedly installed on the inner side wall of the bottom end of the pressure cap, and the torsion spring is slidably sleeved on the outside of the connecting rod, with one end of the torsion spring fixedly installed on the upper side of the rotating ring.

[0011] Preferably, an arc-shaped plate is fixedly installed inside the arc-shaped groove, and an arc-shaped opening is provided on the arc-shaped plate, through which the L-shaped rod slides.

[0012] Preferably, the vertical rod extends into the hollow limiting rod, and the vertical rod matches the hollow limiting rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this invention, the pressure cap drives the L-shaped rod and piston plate to rotate to the left, and then the pressure cap is pressed down, and the faucet starts to flow water. During the downward movement of the pressure cap, the L-shaped rod will move downward, and then the L-shaped rod will drive the piston plate to slide in the sliding air hole on the side with the airflow restriction mechanism. In this way, the air in the sliding air hole will be discharged through the vent pipe and the micro air return hole. Then, during the resetting process of the pressure cap, the air can only flow back to the sliding air hole through the micro air return hole, so that the pressure cap reduces the rebound speed under the traction of the piston plate and L-shaped rod, thereby prolonging the water flow time of the faucet, avoiding the user from pressing repeatedly, and making it convenient for the user to use this type of faucet.

[0015] 2. In this invention, when the user needs a normal water flow time, rotating the pressure cap moves the L-shaped rod and piston plate to the right, causing the piston plate to enter the sliding air hole on the side without the airflow restriction mechanism, thus maintaining the normal water flow time. This allows the user to select the water flow time according to their needs, ensuring the self-resetting faucet's good water-saving effect. 3. In this invention, by setting a hollow limiting rod, a movable groove, and a push block in conjunction with a push plate, the user can easily move the push block up and down using the push plate. When the push block moves up and down, it causes the vertical rod to move up and down. When the vertical rod enters the hollow limiting rod, it acts as a limit, facilitating the installation of the arc-shaped block on the rod. When the vertical rod moves out of the hollow limiting rod, the user can easily remove the arc-shaped block from the rod, facilitating installation and disassembly. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0028] Please see Figures 1-9 A self-resetting faucet includes a stem 1 and a pressure cap 2. A connecting rod 8 is fixedly installed at the upper end of the stem 1, and the pressure cap 2 is provided on the connecting rod 8. A rotating ring 11 is fixedly sleeved on the side wall of the connecting rod 8, and the rotating ring 11 is located inside the pressure cap 2. A support plate 10 is symmetrically installed on the lower side wall of the rotating ring 11 inside the pressure cap 2, and the support plate 10 slides and abuts against the lower side of the rotating ring 11. An arc-shaped block 4 is fixedly installed on the outer side wall of the stem 1, and an arc-shaped groove 13 is opened on the upper end surface of the arc-shaped block 4. Sliding air holes 15 are symmetrically opened on the bottom walls on both sides of the bottom end of the arc-shaped groove 13, and a vent hole 12 is opened in each of the two sliding air holes 15.

[0029] like Figure 4 As shown, an airflow limiting mechanism is provided in one of the vent holes 12, and a miniature return air hole 21 is provided on the arc-shaped block 4 located on one side of the airflow limiting mechanism. An L-shaped rod 7 is fixedly installed on the outer wall of the pressure cap 2, and a piston plate 14 is rotatably installed on one end of the L-shaped rod 7. The piston plate 14 is slidably disposed in the arc-shaped groove 13.

[0030] Furthermore, the limiting device includes a placement groove 23, which is formed on the surface of the rod body 1. A vertical rod 24 is provided in the placement groove 23. A support block 25 is fixedly connected to the inner wall of the placement groove 23. A movable groove 26 is formed on the surface of the rod body 1. A compression spring 27 is fixedly connected to the inner wall of the movable groove 26. A push block 28 is fixedly connected to the upper end of the compression spring 27. A push plate 29 is fixedly connected to the side wall of the push block 28. The bottom end of the vertical rod 24 passes through the upper surface of the support block 25 and extends into the movable groove 26 and is fixedly connected to the push block 28. A hollow limiting rod 22 is placed in the placement groove 23 and is fixedly connected to the inner wall of the arc-shaped block 4.

[0031] Furthermore, the upper side wall of the pressure cap 2 is provided with a pointer 3. The pointer 3 is arranged in an arc shape, and both ends of the pointer 3 are provided with indicating arrows. Large and small text markings are provided at both ends of the pointer 3, which makes it convenient for users to identify and use.

[0032] Furthermore, such as Figure 3 and Figure 4 As shown, the airflow limiting mechanism includes a vent pipe 17, which is fixedly inserted into the vent hole 12. A limiting rod 18 is fixedly installed on the inner side wall of the vent pipe 17, and a spring telescopic rod 19 is fixedly installed on the side wall of the limiting rod 18. An airflow blocking plate 20 is fixedly installed at one end of the spring telescopic rod 19. During the downward movement of the piston plate 14, the air in the sliding vent 15 will push the airflow blocking plate 20 in the vent pipe 17 to move, so that the vent pipe 17 can be ventilated. In this way, the air in the sliding vent 15 will be discharged through the vent pipe 17 and the micro return vent 21. Then, during the reset of the pressure cap 2, the piston plate 14 moves upward, and the airflow blocking plate 20 will be reset under the action of the spring telescopic rod 19, thus limiting the airflow direction.

[0033] Furthermore, such as Figure 2 As shown, limit blocks 16 are symmetrically installed on both sides of the inner side of the arc groove 13, and the two limit blocks 16 are located on one side of the two sliding air holes 15 respectively. The limit blocks 16 can ensure that the piston plate 14 can be accurately aligned with the sliding air holes 15 after the rotation angle, thus facilitating operation by the user.

[0034] Furthermore, such as Figure 2 As shown, a torsion spring 9 is fixedly installed on the inner side wall of the bottom end of the pressure cap 2, and the torsion spring 9 is slidably sleeved on the outside of the connecting rod 8. One end of the torsion spring 9 is fixedly installed on the upper side of the rotating ring 11. Through the torsion spring 9, when the pressure cap 2 drives the L-shaped rod 7 and the piston plate 14 to slide out of the sliding air hole 15, the elastic force of the torsion spring 9 will automatically drive the pressure cap 2 to rotate on the connecting rod 8, thereby driving the L-shaped rod 7 and the piston plate 14 to the middle position of the arc groove 13 for easy movement next time.

[0035] Furthermore, such as Figure 1 As shown, an arc plate 5 is fixedly installed inside the arc groove 13, and an arc-shaped slot 6 is opened on the arc plate 5. An L-shaped rod 7 is slidably installed through the arc-shaped slot 6. The arc plate 5 can protect the components inside the arc block 4.

[0036] Furthermore, the vertical rod 24 extends into the hollow limiting rod 22, and the vertical rod 24 matches the hollow limiting rod 22.

[0037] Working principle: When the user needs water for a longer period of time, they rotate the pressure cap 2 according to the indicator 3 on the pressure cap 2. The pressure cap 2 will rotate on the connecting rod 8, causing the pressure cap 2 to drive the L-shaped rod 7 and piston plate 14 to rotate to the left. The piston plate 14 moves to the left within the arc groove 13 on the arc block 4. Then, the pressure cap 2 is pressed down, causing it to move downwards, and the faucet starts to dispense water. During the downward movement of the pressure cap 2, the L-shaped rod 7 will move downwards, and then the L-shaped rod 7 will drive the piston plate 14 to slide in the sliding air hole 15 on the side with the airflow limiting mechanism. During the downward movement, the air in the sliding air hole 15 will push the airflow blocking plate 20 in the vent pipe 17 to move, allowing air to pass through the vent pipe 17. Air in the vent 15 is discharged through the vent pipe 17 and the micro air return hole 21. Then, during the reset of the cap 2, the piston plate 14 moves upward, and the airflow blocking plate 20 is reset by the spring telescopic rod 19. In this way, air can only flow back to the sliding vent 15 through the micro air return hole 21, which reduces the rebound speed of the cap 2 under the traction of the piston plate 14 and the L-shaped rod 7, thereby extending the water flow time of the faucet. When the user needs the water flow time to be normal, the cap 2 is rotated to move the L-shaped rod 7 and the piston plate 14 to the right, so that the piston plate 14 enters the sliding vent 15 on the side without the airflow restriction mechanism. In this way, the cap 2 will not be pulled when it rebounds, thus maintaining the normal water flow time.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
