Description

Technical Field

[0001] The utility model relates to a drip-proof curved pipe faucet direct water outlet structure. Background Art

[0002] The existing elbow faucet has a direct water outlet structure, and the water outlet elbow directly discharges water.

[0003] The Chinese invention patent authorization announcement number is CN111021480B, and the name is a kitchen faucet. It includes a J-shaped tube body, the tube body includes a curved tube, a sealing ring is provided at the front end of the curved tube, and the tube body also includes a straight tube. The lower end of the straight tube is provided with a water outlet regulating valve, and the water outlet regulating valve includes a valve cavity, and a water outlet bin is installed on the upper part of the valve cavity, and a detergent injection device is installed above the water outlet bin. The faucet of the invention directly discharges water from the spout tube, which is one of the water outlet forms of the curved tube faucet. However, in the direct water outlet structure of this curved tube faucet, when the valve core is opened, the air in the spout tube is compressed by the water pressure; when the valve core is closed, air will remain at the highest point of the spout tube. At this time, because the air pressure inside the spout tube is greater than the external air pressure, the air in the spout tube will squeeze out the residual water. This pressure relief process is the water stopping process of the water outlet after the faucet valve core is closed, which will cause the water outlet of the spout tube to fail to stop water immediately or the water stopping time is too long.

[0004] It is necessary to design a straight water outlet structure of an elbow faucet, which can quickly stop water when the valve core is closed. Utility Model Content

[0027] Please refer to Figures 1 to 5 A preferred embodiment of a drip-proof elbow faucet direct water outlet structure, the drip-proof elbow faucet direct water outlet structure comprises a faucet body 10, a water spout pipe 20 and a drip-proof structure.

[0028] The faucet body 10 includes a faucet housing 11, a clamping ring 12 and a locking screw 13. The water inlet end of the faucet pipe 20 is provided with a water inlet joint 21, which is inserted into the top of the faucet housing 11. The outer periphery of the water inlet joint 21 is provided with a clamping ring groove 22, and the clamping ring 12 is clamped in the clamping ring groove 22. The faucet housing 11 is provided with a screw hole 14, and the locking screw 13 is threadedly engaged with the screw hole and its end is pressed against the clamping ring 12 to axially limit the water inlet joint 21. Figure 2 As shown, the clamping rings 12 are provided in two groups and are spaced apart from each other.

[0029] In this embodiment, the direct water outlet structure further includes a second sealing ring 15, which is sandwiched between the water inlet joint 21 and the faucet housing 11. Figure 2 As shown, two second sealing rings 15 are provided and are spaced apart from each other.

[0030] In this embodiment, the direct water outlet structure further includes a wear-resistant pad 16 , which is sandwiched between the water inlet joint 21 and the top end surface of the faucet housing 11 .

[0031] like Figure 4 As shown, the faucet body also includes an inner body, a valve core, a handle and other structures, which belong to the prior art and will not be described in detail.

[0032] The water inlet end of the spout pipe 20 is connected to the top of the faucet body 10. The anti-drip structure includes a water outlet joint 30 and a hose 40 that can discharge water and exhaust air at the same time. The water outlet joint 30 is fixedly connected to the water outlet end of the spout pipe 20 and is provided with an assembly cavity 31 that passes through from top to bottom. The bottom end of the hose 40 is connected to the assembly cavity 31. The hose 40 extends upward along the inner wall of the spout pipe 20 and its top end is located at the highest point of the inner wall of the spout pipe 20. When the spout pipe 20 discharges water, the air in the spout pipe 20 can be discharged along with the water flow. Figure 2 As shown, the hose 40 extends upward along the top wall of the faucet tube 20 to discharge the air at the highest point in the faucet tube 20 to the maximum extent.

[0033] In this embodiment, the water outlet joint 30 is connected to the water nozzle pipe 20 by welding.

[0034] In this embodiment, the inner wall of the assembly cavity 31 is provided with a first step surface 32 and a second step surface 33, and the hose 40 includes a hose body 41 and a hose connector 42 fixedly connected to the bottom end of the hose body 41, and the bottom end of the hose connector 42 is located in the assembly cavity 31 and the hose connector 42 is against the first step surface 32; the direct water outlet structure also includes a hollow pressure cover 50, which is installed in the assembly cavity 31 and its top end surface is limitedly matched with the second step surface 33, and the hose connector 42 is against the pressure cover 50.

[0035] In this embodiment, the pressure cover 50 is threadedly engaged with the inner wall of the assembly cavity 31 .

[0036] In this embodiment, the direct water outlet structure further includes a first sealing ring 60 , which is sandwiched between the hose connector 42 and the inner wall of the assembly cavity 31 .

[0037] In this embodiment, the direct water outlet structure further includes a bubbler 70, which is installed in the assembly cavity 31 and is located below the gland 50. Specifically, Figure 5 As shown, the inner wall of the assembly cavity 31 is further provided with a third step surface 34 , and the top end of the bubbler 70 is against the third step surface 34 .

[0038] When the water outlet pipe of the direct water outlet structure is discharging water, Figure 2 As shown, water enters the water nozzle tube 20 from the water inlet end of the water nozzle tube 20. When the water flow reaches the highest point, it enters the hose 40. At this time, the air located at the highest point of the inner wall of the water nozzle tube 20 will enter the hose 40 along with the water flow, and flow along the hose 40 through the gland 50 and the bubbler 70 before flowing out of the water nozzle tube 20. When the water nozzle tube 20 stops discharging water, no air remains in the water nozzle tube 20, so that the water can be stopped quickly.

[0039] The anti-drip structure can not only achieve rapid water stopping, but also the top of the hose 40 is located at the highest point of the inner wall of the water nozzle pipe 20, so that the air in the water nozzle pipe 20 can flow out synchronously with the water flow during the water outlet process of the water nozzle pipe 20. When the water source is turned off, since there is little or no air in the water nozzle pipe 20, the pressure relief time is very short or there is no pressure relief time, thereby reducing the water stopping time and improving the quality of the faucet. Moreover, the anti-drip structure can be assembled with the conventional water nozzle pipe of the straight water outlet structure, without the need to replace the entire faucet, with strong compatibility and reduced production costs.

[0040] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
