Description

Technical Field

[0001] This utility model relates to a kitchen and bathroom product, and more particularly to a pull-out faucet. Background Technology

[0002] Pull-out faucets, with their flexible extendable design and multi-angle rinsing capabilities, have become an important piece of equipment for enhancing convenience in modern kitchens and bathrooms. Existing pull-out faucets mostly employ a fixed weight, an independent movable weight, or a pure spring-loaded return mechanism. With a fixed weight, the pull tube and weight are relatively fixed, resulting in a shorter pull-out stroke and a smaller cleaning area. With an independent movable weight, the weight is always at the lowest point of the pull tube, distributing gravity to both sides of this point. Therefore, the return force acting on the movable side of the pull tube is approximately half the weight of the weight. Thus, a light weight results in poor return performance, while a heavy weight significantly increases cost and requires more effort, leading to a poor user experience. Pull-out faucets with a pure spring-loaded return mechanism suffer from large fluctuations in pull force and noise due to the spring's elasticity being related to the pull-out stroke, resulting in a poor user experience. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a movable weight pull-out structure to improve the reset force and reset effect, and to increase the pull-out stroke while keeping the length of the pull-out tube unchanged.

[0004] To solve the above-mentioned technical problems, this utility model provides a movable weight pull-out structure, including: a pull-out tube, a movable weight passing through the pull-out tube, and an elastic element passing through the outside of the pull-out tube; the pull-out tube is divided into a movable side and a fixed side with the lowest point when it is not pulled out as the boundary; one end of the elastic element acts on the movable weight, and the other end remains stationary relative to the fixed side of the pull-out tube.

[0005] The elastic element is used to provide resistance to the movement of the movable weight towards the fixed side when the pull tube is pulled out, so as to keep the movable weight on the movable side of the pull tube.

[0006] In a preferred embodiment: when the pull tube is not pulled out, the movable weight is located on the movable side or the lowest point of the pull tube.

[0007] In a preferred embodiment: the elastic element is a spring.

[0008] This utility model also provides a pull-out faucet, characterized by being equipped with the pull-out structure described above.

[0009] In a preferred embodiment, the faucet body, support pipe, and pull-out shower head are also included. The faucet body has a hot water inlet channel and a cold water inlet channel, and the support pipe has a mixed water outlet channel. The fixed side of the pull-out pipe is connected to the mixed water outlet channel, and the movable side passes through the faucet body and is connected to the pull-out shower head.

[0010] In a preferred embodiment: the support tube has a fixed surface, and when the pull-out tube is not pulled out, the pull-out shower head and the faucet body are limited and engaged in the opposite direction of the pull-out tube being pulled out.

[0011] In a preferred embodiment: the support pipe is a support bend, and the end of the support bend is the fixed surface, so that when the pull-out pipe is not pulled out, the water outlet surface of the pull-out shower head faces downward.

[0012] In a preferred embodiment: a temperature regulating valve core is provided inside the faucet body, the hot water inlet channel and the cold water inlet channel are respectively connected to the inlet of the temperature regulating valve core, and the outlet of the temperature regulating valve core is connected to the mixed water outlet channel.

[0013] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0014] This invention provides a movable weight pull-out structure. Compared to a traditional fixed weight, the movable weight can compress the spring to obtain an additional stroke, thus increasing the pull-out stroke. Compared to a traditional movable weight, the movable weight remains on the moving side of the pull-out tube during the pull-out process, ensuring that the weight's force acts entirely on the moving side of the pull-out tube, thereby increasing the restoring force.

[0017] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0018] refer to Figure 1 and Figure 2 This embodiment provides a pull-out faucet, including a support pipe 1, a faucet body 4, a pull-out shower head 2, and a pull-out pipe 3. The faucet body 4 has a hot water inlet channel and a cold water inlet channel, while the support pipe 1 has a mixing outlet channel. The hot water inlet channel and the cold water inlet channel are connected to a cold water angle valve and a hot water angle valve on the wall, respectively, via a cold water inlet hose 5 and a hot water inlet hose 6. The cold water inlet channel 5 and the hot water inlet channel 6 pass through a temperature-adjusting mixing valve 7 on the faucet body 4 and then exit through the mixing outlet channel, discharging temperature-adjusting water. The temperature-adjusting mixing valve 7 also has a water on / off function. Specifically, the temperature-adjusting mixing valve 7 is linked to a switch handle. By adjusting the switch handle, the flow area between the temperature-adjusting mixing valve 7 and the cold water inlet channel 5 and the hot water inlet channel 6 can be adjusted, thereby adjusting the ratio of cold water to hot water entering the temperature-adjusting mixing valve 7 and thus regulating the temperature of the mixed water. One end of the pull-out pipe 3 is connected to the mixed water outlet channel to form a fixed side 33, and the other end of the pull-out pipe 3 passes through the faucet body 1 and is connected to the pull-out shower head 2 to form a movable side 34. The pull-out pipe 3 has a lowest point when it is not pulled out, and the movable side 34 and the fixed side 33 are located on both sides of the lowest point.

[0019] A movable weight 31 and an elastic element 32 are also installed on the pull-out tube 3. One end of the elastic element 32 acts on the movable weight 31, while the other end remains stationary relative to the fixed side 33 of the pull-out tube 3. When the pull-out tube 3 is not pulled out, the movable weight 31 is located on the movable side 34 or at its lowest point. After the above arrangement, when the pull-out tube 3 is pulled out, the movable weight 31, being movably connected to the pull-out tube 3, tends to move towards the fixed end of the pull-out tube 3. Due to the presence of the elastic element 32, the elastic element 32 provides resistance to the movable weight 31 as it moves towards the fixed side 33, thereby keeping the movable weight 31 on the movable side 34 of the pull-out tube 3. Since the movable weight 31 is always located on the movable side 34 of the pull-out tube 3, the entire weight of the movable weight 31 acts on the movable side 34, thus increasing the restoring force of the pull-out tube 3 and making the restoring of the pull-out tube 3 smoother. Conversely, since the entire weight of the movable weight 31 acts on the movable side 34, a lighter movable weight 31 can achieve the same restoring force, thus reducing the resistance the user needs to overcome when pulling the pull tube 3 and improving the pull-out feel. Furthermore, because the movable weight 31 can compress the elastic element 32, causing a certain deformation, an additional pull-out stroke is obtained. Therefore, compared to the fixed weight solution, the pull-out stroke can be maximized without increasing the length of the pull tube 3.

[0020] In this embodiment, a support pipe 1 is installed on the faucet body 4. The support pipe 1 is a support bend, and the end of the support bend is a fixed surface. When the pull-out pipe 3 is not pulled out, the pull-out shower head 2 and the support pipe 1 are limited and matched in the opposite direction of the pull-out pipe 3. At this time, the water outlet surface of the pull-out shower head 2 is downward. In this way, the pull-out shower head 2 can also be used as a normal fixed faucet when it is not pulled out.

[0021] In this embodiment, the elastic element 32 is a spring, specifically a helical spring, which is sleeved and wound around the fixed side of the pull tube 3.

[0022] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
