Description

technical field [0001] The invention relates to a water faucet, in particular to a rotary regulating type clean water faucet. Background technique [0002] In daily life, the faucet is a valve switch used to control the size of the water flow, which has the effect of saving water. There are many types of faucets. Because the water outlet pipe of the rotary control type clean water faucet can rotate freely, the direction of the water outlet can be adjusted according to the needs of use. , the most widely used in people's lives, it avoids the phenomenon of wasting water resources caused by inappropriate directions of water outlets in life. [0003] Such as figure 1 , the existing rotary adjustable water purification faucet mainly includes a faucet body 1', a water purification pipe body 2', a rotating centering 3' and a water outlet pipe 4', and the outlet of the water purification pipe body 2' and the faucet body 1' connected to the water outlet, the rotating centering 3' ...

AI Technical Summary

Problems solved by technology

[0003] like figure 1 , the existing rotary adjustable water purification faucet mainly includes a faucet body 1', a water purification pipe body 2', a rotating centering 3' and a water outlet pipe 4', and the outlet of the water purification pipe body 2' and the faucet body 1' connected to the water outlet, the rotating centering 3' is set on the water outlet of the water purification pipe body 2', and one end of the water outlet pipe 4' is provided with a swivel joint 41', and the peripheral outer wall of the swivel joint 41' is formed by There are two O-rings 5' at intervals from top to bottom. The outlet pipe 4' is rotatably arranged on the rotation centering 3' through the rotary joint 41' on it. In order to make the outlet pipe 4' longitudinally fixed but not It is still rotatable in the radial direction and is arranged on the rotary centering 3'. An axial positioning device is also provided between the rotary joint 41' and the rotary centering 3'. The axial limiting device includes a snap spring 6' and screw 7', the rotary joint 41' is located above the two O-rings 5' with a circlip groove, the circlip 6' is set in the circlip groove, and rotates on the outside of the rotation centering 3'. A screw hole is opened at the position corresponding to the circlip 6' on the joint 41'. The screw 7' is screwed in from the outside of the rotation centering 3' and then connected with the circlip 6' of the rotary joint. This axial positioning method Although the axial movement between the outlet pipe and the rotary centering is limited, this axial positioning method has the following disadvantages:

[0004] 1. The structure is complex and impractical. It is necessary to drill holes on the outer side of the rotation centering circle for screws to be screwed into the limit. The faucet is particular about appearance, and screwing the screws on the drilling holes will affect its promotion and sales. The location of the drilled hole is located on the back of the faucet. It often takes a long time to reassemble and rotate the centering. The labor cost is high. The faucet is often in contact with water. The screws are easy to rust and loosen. The axial positioning effect is not good. The phenomenon of water leakage at the position of the screw hole, poor sealing performance and short service life

[0005] 2. The manufacturing cost is high. Drilling will increase the production process of the water purification faucet, and the drilling process is complicated, and waste products are prone to appear during processing, which affects the quality of the finished product. Increase the inspection work in the later stage, reduce production efficiency, and increase production costs.

[0006] 3. The stability of the axial limit is poor and the service life is short. Since the pressure of the water is radial, using a screw to tighten a point in the radial direction of the circlip will cause uneven force, and the contact surface between the two will be distorted when rotating. A large swing is generated, which makes the rotation not smooth, and the radial pressure generated by the circlip and the O-ring is large, which is easy to be worn out, the stability of the axial limit is poor, the sealing performance is not good, and the joint of the rotation is prone to water leakage, which increases maintenance. cost, short lifespan
