Description
Technical Field
[0001] The utility model relates to the field of faucets, in particular to an anti-freezing and water-saving faucet. Background Art
[0002] A faucet is a water outlet device for controlling the flow rate of water. The lower end of the faucet body is directly connected to the water inlet pipeline, and there is a faucet valve at the position where the faucet body communicates with the faucet neck. The faucet valve can be opened and closed by a handle. When the user opens the faucet valve through the handle, the water flow entering the faucet body from the water inlet pipeline will enter the faucet neck through the faucet valve and finally flow out through the faucet nozzle at the end of the faucet neck for use.
[0003] It can be seen from this that when the faucet is closed, the faucet valve can intercept the subsequent water flow in the faucet body, but the water flow in the faucet neck will still flow out through the faucet nozzle under the action of the inertia of water flow for use. At this time, the user has already ended the use of the water flow, resulting in the waste of this part of the water flow. In order to avoid this situation, a water-saving structure will be installed at the faucet nozzle. When the faucet valve is closed, the water-saving structure at the faucet nozzle will also close the faucet nozzle to achieve the water-saving effect. However, in the actual use of the faucet, some faucets will be installed outdoors, and the faucets outdoors are extremely vulnerable to the influence of the environment. Especially in cold winter weather, the outdoor temperature is extremely easy to reach below zero. At this time, if the water flow in the faucet neck is in a static state, it is extremely easy to be frozen by low temperature. Even if the faucet valve can be normally opened through the handle, the water flow cannot flow out through the faucet neck from the faucet nozzle, resulting in the faucet being unable to be used normally.
[0004] When it is realized that the faucet will not be used for a long time, if the water-saving structure in the faucet nozzle is actively removed to drain the water flow intercepted in the faucet neck completely, although the freezing inside the faucet neck can be avoided, the frequent disassembly and assembly of the water-saving structure will make the water use troublesome.

[0028] An installation hole 36 that fits with the inside of the faucet neck 2 is provided on the lower surface of the left end of the faucet neck 2, and the upper end of the faucet spout 3 is screwed into the installation hole 36.
[0029] The usage method of the present utility model is as follows:
[0030] When the faucet needs to be used, the faucet valve can be opened through the handle 4. After the faucet valve is opened, the water flow in the water inlet pipeline connected to the faucet body 1 will enter the faucet neck 2 through the faucet body 1. As the subsequent water flow continuously surges into the faucet neck 2, the water flow will pass through the middle of the faucet neck 2 and continue to flow towards the left end of the faucet neck 2. When the water flow passes through the middle of the faucet neck 2, the water flow will enter the communication hole 10 through the water inlet hole 11. Since the elasticity of the middle spring 17 is greater than the elasticity of the left spring 29, without external force, only relying on the water flow pressure, it is impossible to push the middle closing head 13 downward, so that the lower end hole of the communication hole 10 always remains blocked and sealed by the middle closing head 13. As the water flow continues to flow leftward, the water flow will enter the water outlet hole 24 through the water delivery hole 25. At this time, the water flow pressure is greater than the elasticity of the left spring 29, and the water flow entering the water outlet hole 24 will push the left closing head 30 downward. At this time, the left sealing cone surface 31 leaves the lower end hole of the water outlet hole 24, and the lower end hole of the water outlet hole 24 is in an open state, and the water flow can flow out to the outside through the water outlet hole 24 for use.
[0031] When the faucet is not needed, the faucet valve can be closed by the handle 4. As the faucet valve is closed, the water flow in the water inlet pipe will be retained in the faucet body 1 for the first time, and the water flow in the faucet neck 2 loses the push of the subsequent water flow, and the water pressure inside the faucet neck 2 drops sharply. At this time, the water flow pressure in the faucet neck 2 is less than the elasticity of the left spring 29, and the left opening and closing head 30 will move up and reset under the elastic action of the left spring 29, and the lower end of the water outlet 24 will be blocked and sealed by the left sealing cone surface 31 again, so that the water flow in the faucet neck 2 is retained in the faucet neck 2. When the faucet is opened again, the water flow remaining in the faucet neck 2 can be used as the first water flow, thereby saving water.
[0032] When the user finds that the outdoor temperature is too low and he does not use the faucet for a long time, the water in the faucet neck 2 can be drained, which effectively avoids the situation where the water in the faucet neck 2 freezes and the faucet cannot be used normally. When the water in the faucet neck 2 needs to be drained, the limit cover 15 can be held and pressed down. When the limit cover 15 moves down, the middle spring 17 is compressed. When the limit cover 15 moves down a certain stroke, the internal thread 16 of the inner wall of the cover opening at the lower side of the limit cover 15 will contact the external thread 9 on the outer wall of the upper end of the water diversion body 8. At this time, the limit cover 15 can be rotated to make the limit cover 15 screwed to the outside of the upper end of the water diversion body 8. Since the lower end of the water diversion body 8 is restricted from moving downward by the bottom of the positioning hole 6, the limit cover 15 can be easily screwed to the water diversion body 8. Outside the upper end of the water body 8, when the limit cover 15 moves downward, the lifting rod 12 will move downward with the middle opening and closing head 13 along the trajectory of the lifting hole 14, and the middle opening and closing head 13 will be away from the lower end opening of the connecting hole 10. When the limit cover 15 is screwed and fixed to the upper end of the water diversion body 8, the middle opening and closing head 13 remains in a fixed state, and the lower end opening of the connecting hole 10 remains in a normally open state. At this time, the water flow remaining in the faucet neck 2 can be discharged to the outside through the water inlet hole 11, the connecting hole 10, the gap between the outer wall of the middle opening and closing head 13 and the inner wall of the drainage hole 7, and the lower end opening of the drainage hole 7 in sequence, and finally the water flow in the faucet neck 2 is drained, and the drainage hole 7 can also be used for water discharge. When it is inconvenient for the faucet mouth 3 to discharge water, the drainage hole 7 can be used to discharge water to ensure normal water use.
[0033] From the above, it can be seen that the utility model can utilize the water-saving structure at the left end of the faucet neck 2 to achieve a water-saving effect, and can utilize the drainage hole 7 in the middle of the faucet neck 2 for drainage. When drainage is needed, it is only necessary to press down the limit cover 15 and screw the limit cover 15 to the outside of the upper end of the water diversion body 8, so that the water in the faucet neck 2 can be drained through the drainage hole 7. The whole drainage process is extremely simple and can effectively ensure the drainage efficiency. As the water in the faucet neck 2 is drained, it can effectively avoid the water trapped in the faucet neck 2 by the water-saving structure from freezing, resulting in the faucet being unable to discharge water normally.
[0034] A connection hole 19 is provided at the center of the limit cover 15. The upper end of the lifting rod 12 passes upward through the connection hole 19 and is screwed with a middle nut 20 that fits against the upper surface of the limit cover 15. On the inner walls of the left and right sides of the lower end orifice of the connection hole 19, there are symmetrically arranged limit grooves 21. On the left and right sides of the lifting rod 12, there are limit portions 22 that match the limit grooves 21. The existence of the limit portions 22 can fix the limit cover 15 on the lifting rod 12, preventing the limit cover 15 from rotating around the lifting rod 12, thereby ensuring the stability when the limit cover 15 is fixed to the lifting rod 12 under the action of the middle nut 20.
[0035] On the outer wall of the lower end of the water-saving seat 23, there is a positioning portion 32 that fits against the lower surface of the faucet nozzle 3. On the outer wall of the positioning portion 32, there is a hexagon-shaped clamping surface 33. The existence of the positioning portion 32 can ensure that the water-saving seat 23 is screwed into the faucet nozzle 3 in place, avoiding the situation where the water-saving seat 23 goes too deep into the faucet nozzle 3. And the existence of the clamping surface 33 facilitates disassembly and assembly. The user can use a corresponding wrench to clamp on the clamping surface 33, and then easily rotate the positioning portion 32, thereby easily rotating the water-saving seat 23 to complete the disassembly and assembly of the water-saving seat 23.
[0036] At the center of the lower surface of the left opening and closing head 30, there is a pull ring 34, which facilitates the user to pull down the left opening and closing head 30 through the pull ring 34, thereby discharging all the water remaining in the water outlet hole 24 to the outside, effectively avoiding the situation of freezing due to water remaining in the water outlet hole 24.
[0037] On the outer wall of the upper end of the water distribution body 8, there is a hexagon-shaped disassembly and assembly surface 35. When the user disassembles and assembles the water distribution body 8, the corresponding wrench can be clamped on the disassembly and assembly surface 35 to quickly complete the disassembly and assembly of the water distribution body 8.
[0038] On the lower surface of the left end of the faucet neck 2, there is a mounting hole 36 that fits against the inside of the faucet neck 2. The upper end of the faucet nozzle 3 is screwed into the mounting hole 36. This fixing method facilitates the disassembly and assembly of the faucet nozzle 3, thereby facilitating the maintenance and replacement of the faucet nozzle 3 and the water-saving structure.
