[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a self-controlled flow-limiting faucet, including: a faucet body 1, a water inlet pipe 2 connected to one end of the faucet body 1, a water outlet pipe 3 connected to the bottom end of the faucet body 1, and a valve stem 4 connected to the inner side of the faucet body 1.

[0025] Specifically, such as Figure 2 As shown, a fastening cap 5 is connected to the outside of the water outlet pipe 3, and the water distribution pipe 6 is fixedly connected to the inside of the water outlet pipe 3. The fastening cap 5 is used to lock the water outlet pipe 3 and the water nozzle body 1.

[0026] An automatic flow limiting component is provided on the inner side of the outlet pipe 3. The automatic flow limiting component includes a water distribution pipe 6. A conical elastic diaphragm 8 is connected to the bottom end of the water distribution pipe 6. A flow limiting orifice plate 11 is connected to the bottom end of the conical elastic diaphragm 8. The automatic flow limiting component is used for automatic flow limiting of the water faucet.

[0027] Specifically, such as Figure 4 As shown, a cross-shaped partition 7 is fixedly installed on the inner side of the water distribution pipe 6, and a conical elastic diaphragm 8 is connected to the bottom end of the cross-shaped partition 7. The cross-shaped partition 7 is used to divert and regulate the flow direction of the water.

[0028] Specifically, such as Figure 4 As shown, the inner side of the conical elastic diaphragm 8 is provided with a diversion groove 9. There are three diversion grooves 9 arranged in a ring. The conical elastic diaphragm 8 is conical, and the tip extends three diversion grooves 9, which facilitates the adjustment of the opening and closing amplitude of the conical elastic diaphragm 8.

[0029] Specifically, such as Figure 4 As shown, an elastic cavity tube 10 is fixedly connected to the outer side of the bottom end of the conical elastic diaphragm 8, and a flow limiting plate 11 is fixedly connected to the bottom end of the elastic cavity tube 10. The conical elastic diaphragm 8 and the elastic cavity tube 10 are made of rubber, which will deform when impacted by water flow to offset the impact force of water flow.

[0030] A locking connection assembly is provided on the inner side of the faucet body 1. The locking connection assembly includes a handle 14 and a locking plate 15 is provided on the inner side of the handle 14. The locking connection assembly is used to lock the faucet.

[0031] Specifically, such as Figure 2 As shown, a fitting rubber ring 12 is sleeved on the inner side of the valve stem 4. The fitting rubber ring 12 fits on the inner side of the water nozzle body 1 and the valve stem 4 to improve the sealing of the adjustment. A sealing cap 13 is connected to the top of the outer side of the valve stem 4. The sealing cap 13 is used to limit the rotation position of the valve stem 4. The handle 14 is rotatably connected to the top of the valve stem 4. After the handle 14 is rotated, it is used to rotate the valve stem 4 to adjust the opening and closing of the water nozzle body 1.

[0032] Specifically, such as Figure 2 As shown, the locking plate 15 is fixedly connected to the outside of the water nozzle body 1. The shape of the locking plate 15 is adapted to the internal slot of the handle 14. The locking plate 15 has a hole inside for inserting a spring lock to lock it.

[0033] Specifically, such as Figure 2 As shown, a valve ball 17 is fixedly connected to the bottom end of the valve stem 4, and a sealing seat 16 is connected to the outside of the valve ball 17. The sealing seat 16 fits against both sides of the valve ball 17 to improve the sealing performance of the valve ball 17 during adjustment.

[0034] In this embodiment: a water distribution pipe 6 is installed inside the outlet pipe 3 to divert the water flow. Then, the water flow is automatically regulated under high water pressure by the elastic blocking of the conical elastic diaphragm 8 and the elastic cavity tube 10, so that the water flow is diverted after being blocked, thus achieving the effect of automatic regulation and preventing splashing. A locking plate 15 is set on the outside of the water nozzle body 1 to lock and limit the handle 14 when it is rotated to the locked position. The inner side of the locking plate 15 is provided with a hole adapted to the spring lock hook for locking the handle 14 to prevent accidental operation.

[0035] The specific steps of this solution are as follows: During the installation of the faucet, the inlet pipe 2 and outlet pipe 3 are installed separately. The outlet pipe 3 is tightened by tightening the cap 5. Inside the faucet body 1, the valve stem 4 connects to the valve ball 17 to control the water flow switch. The rotation of the valve stem 4 is controlled by the handle 14. When not in use, the handle 14 can be locked on the outside of the locking plate 15 to prevent accidental activation. During the use of the faucet, the water pressure will vary. When the water pressure is low, the water flows through the distribution pipe 6. The flow is diverted and slowed down by the cross-shaped partition 7, and then flows directly through the holes inside the conical elastic diaphragm 8 and out through the flow-limiting orifice plate 11. When the water pressure is high, the opening inside the conical elastic diaphragm 8 is difficult to adapt to the flow rate, which will squeeze the conical elastic diaphragm 8, causing the diversion groove 9 to expand and the elastic cavity tube 10 to be compressed, so that the bottom of the conical elastic diaphragm 8 is inserted into the middle of the flow-limiting orifice plate 11. The elastic compression relieves the water pressure, slows down the water flow, and improves the self-control flow-limiting effect of the water nozzle.

[0036] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.

[0037] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
