Description

Bendable positioning structure of faucet outlet pipe

The present invention relates to a faucet structure, in particular to a bendable positioning structure of a faucet outlet pipe.

Faucets are one of the indispensable water supply tools in human life, and the development of faucets has also led to the improvement of the application of "washing methods" by humans. For example, different faucet structures are gradually applied to wash basins, kitchen sinks, and wash basins to provide consumers with more diverse special styles, which are all extended designs of faucets. Because of these faucets designed for special purposes, people's water use is more convenient.

The faucets installed on general sinks are mostly designed in a vertical style. For the convenience of water control, the water control valve is often planned to be located on the side of the faucet body, and the water outlet is located on the top of the faucet body. However, when facing the need to clean the sink after use, the water outlet of this type of faucet cannot cover the entire sink. Therefore, the industry has developed an inner tube faucet, in which a soft inner tube is installed inside the water outlet pipe, and one end of the soft inner tube is connected to the inner tube. After passing through the faucet body, the connection assembly is installed on the water outlet spiral pipe connected to the water control valve, and the other end of the soft inner pipe is assembled with a water outlet head, and the water outlet head can be sleeved and engaged on the outer end of the water outlet pipe. In this way, in addition to normal water use, when facing the need to clean the kitchen sink or other larger areas, the soft inner pipe can be pulled out from the water outlet head and the water outlet head can be extended to the desired water use location, thereby providing flexible water use patterns and giving better practical value.

However, in the conventional faucet structure, the soft inner tube inserted into the water outlet pipe will naturally fall down due to gravity, causing the soft inner tube to contact and rub against the inner wall of the water outlet pipe. When the soft inner tube is stretched outward or retracted inward, it is easy to produce a warp phenomenon due to eccentricity, resulting in the soft inner tube not sliding smoothly or even interfering and getting stuck, causing inconvenience to the user and affecting its overall practicality.

The inventor of the present invention, in view of the above-mentioned shortcomings of the known faucet structure, came up with the idea of creating a new invention. After much discussion and trial production of samples, as well as many revisions and improvements, the present invention was launched.

The present invention provides a bendable positioning structure for a faucet outlet pipe, comprising: a faucet body, which is composed of a base body with a water outlet cut-off control portion on one side, a water outlet pipe connected to the top, and a positioning piece arranged at the end of the water outlet pipe; a spring tube, which is made of a metal wire wound into a spiral tube body, and the spring tube is sleeved and assembled in the water outlet pipe, and is stopped and positioned by the positioning piece, and the spring tube is provided with large-diameter parts and small-diameter parts arranged alternately. The large diameter part is clamped against the inner wall of the water outlet pipe for positioning; and a soft inner tube can be slidably inserted into the spring tube in the water outlet pipe, and is limited by the small diameter part of the spring tube so that the soft inner tube is kept on the central axis of the water outlet pipe. One end of the soft inner tube is combined with a water outlet head on the outer side of the water outlet pipe. The water outlet head is normally sleeved and clamped on the port of the water outlet pipe, and the water outlet head together with the soft inner tube can be stretched outward according to the use requirements.

The main purpose of the bendable positioning structure of the faucet outlet pipe of the present invention is that the soft inner pipe can be slidably inserted into the spring tube in the outlet pipe to avoid the contact and friction between the soft inner pipe and the inner wall of the outlet pipe, and to ensure that when the soft inner pipe is stretched outward or retracted inward, no warping phenomenon will occur due to eccentricity, so as to ensure that the soft inner pipe slides smoothly without interference and jamming.

The following is a further description of the preferred embodiments of the present invention in conjunction with the drawings, so that those familiar with the relevant technology of the present invention can implement it according to the description of this specification.

First, please refer to the first to sixth figures, the bendable positioning structure of the faucet outlet pipe of the present invention includes: a faucet body 10, a spring tube 20 and a soft inner tube 30.

The faucet body 10 is composed of a cylindrical base 11 with a water outlet control portion 12 on one side, and a water outlet pipe 13 connected to the top. The water outlet pipe 13 is in a curved tube shape with an inner diameter D1. A positioning member 14 is arranged at the end of the water outlet pipe 13, and the positioning member 14 is ring-shaped.

The spring tube 20 is made of a metal wire wound into a spiral tube body. The spring tube 20 is set in the water outlet pipe 13 through its own elastic deformation and is stopped and positioned by the positioning member 14. The spring tube 20 is provided with a large diameter portion 21 and a small diameter portion 22 arranged alternately. The large diameter portion 21 has an outer diameter D2, which is greater than or equal to the inner diameter D1 of the water outlet pipe 13. The large diameter portion 21 is clamped against the inner wall of the water outlet pipe 13 for positioning, so that the spring tube 20 is stably fixed in the water outlet pipe 13.

The soft inner tube 30 can be slidably inserted into the spring tube 20 in the outlet pipe 13, and is limited by the small diameter portion 22 of the spring tube 20, so that the soft inner tube 30 is kept on the central axis of the outlet pipe 13. One end of the soft inner tube 30 is connected to a water outlet head 31 on the outer side of the outlet pipe 13. The water outlet head 31 is normally sleeved and clamped on the port of the outlet pipe 13, and the water outlet head 31 can be stretched outward together with the soft inner tube 30 according to the use requirements.

When in use, under normal water use conditions, the water outlet control unit 12 controls the cold and hot water inlet ratios and the water supply and stop functions, so that the water can flow out through the faucet body 10 and the soft inner tube 30, and out of the water outlet head 31 of the soft inner tube 30. When facing the need to wash the sink or other water needs in a larger range, as shown in Figure 7, the water outlet head 31 can be stretched outward together with the soft inner tube 30 to extend the water outlet to the required water position, giving a larger range of water use functions. When the water outlet head 31 is released, the soft inner tube 30 is retracted inward by the automatic recovery device (not shown in the figure), and the water outlet head 31 is linked to return to its original position. The automatic recovery device is a known technology and is not the focus of this case. Its detailed structure and operating principle will not be described here.

Furthermore, as shown in Figures 8 to 10, another embodiment of the bendable positioning structure of the faucet outlet pipe of the present invention is shown. The difference between the other embodiment and the above embodiment is that a coating layer 23 is provided on the surface of the spring tube 20, and the coating layer 23 contacts the inner wall of the outlet pipe 13 and the outer edge of the soft inner tube 30.

The structure of the above-mentioned specific embodiment can obtain the following benefits: the bendable positioning structure of the faucet water outlet pipe of the present invention, its soft inner tube 30 can be slidably inserted into the spring tube 20 in the water outlet pipe 13, and is limited by the small diameter portion 22 of the spring tube 20, so that the soft inner tube 30 is kept on the central axis of the water outlet pipe 13, so as to avoid the contact and friction between the soft inner tube 30 and the inner wall of the water outlet pipe 13, reduce the friction force when the soft inner tube 30 is pulled outward or retracted inward, ensure that when the soft inner tube 30 is stretched outward or retracted inward, no warping phenomenon will be generated due to eccentricity, ensure that the soft inner tube 30 slides smoothly, and no interference and jamming will occur, thereby improving the convenience and practicality of use.
