Description

Technical Field

[0001] The utility model relates to the field of bathrooms, in particular to a pull-out type water outlet mechanism and a pull-out type faucet. Background Art

[0002] Pull-out faucets are a popular design feature in modern kitchens and bathrooms, favored for their convenience and versatility. Their basic structure consists of the faucet body, pull-out hose, and spout. The faucet body is fixed to the sink or countertop, providing stable support for the entire unit. The pull-out hose is a flexible hose connected to the faucet body at one end and the spout at the other. This allows the user to freely pull the spout out of the faucet body, conveniently controlling the water flow in different directions and positions. This design greatly enhances flexibility and is particularly useful when washing large items or cleaning hard-to-reach areas.

[0003] However, traditional pull-out faucets also present some problems during use. First, when the user lets go, the water head will automatically return to the faucet body under the action of a weight or spring. However, because the connection between the water head and the pull-out tube usually uses a ball joint or a rotatable design, the direction of the water head is often not fixed after returning to its original position. This inconsistent rotation direction can cause inconvenience in use, especially when the user needs to readjust the direction of the water head when using the faucet again. This not only wastes time, but can also cause problems such as splashing water.

[0004] Furthermore, the connection between the pull-out tube and the water outlet is typically a threaded structure. While this design is secure, assembly and disassembly is time-consuming and labor-intensive. The threaded structure requires multiple manual turns to connect or disassemble, increasing the complexity of installation and maintenance. Over time, the threads may become less tight due to wear or scale accumulation, potentially leading to leaks. Therefore, improvements to this connection method are necessary to simplify assembly and disassembly and enhance the user experience. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] See Figures 1-9 A pull-out faucet, comprising a pull-out faucet body and a pull-out water outlet mechanism. The pull-out faucet body is fixedly arranged on a countertop, the pull-out faucet body comprises a curved pipe 11, the pull-out water outlet mechanism comprises a pull-out tube 21, a water outlet head 22 and a connecting cover 23, the pull-out tube 21 can be pulled out of the curved pipe 11, one end of the pull-out tube 21 is connected to the water outlet head 22, and the water outlet head 22 can be abutted against the end of the curved pipe 11. A weight is sleeved on the pull-out tube 21, and the user can freely pull the water outlet head 22 out of the curved pipe 11, conveniently using the water flow in different directions and positions. When the user lets go, the weight can drive the water outlet head 22 back to its initial position.

[0029] The water outlet head 22 includes a connecting wall 221, the wall body of the connecting wall 221 is formed with a clamping part 222, and the outer wall of the connecting wall 221 is formed with a clamping groove 2211; one end of the pull-out tube 21 can be inserted into the connecting wall 221 to be clamped with the clamping part 222, and the clamping part 222 can be pressed to release the clamping connection with the pull-out tube 21, and the connecting cover 23 is sleeved on the outside of the connecting wall 221, and the connecting cover 23 can be clamped on the connecting wall 221 through the clamping groove 2211; the outer wall of the connecting cover 23 also includes a guide slope 231, and the guide slope 231 can correspond to the positioning slope 12 of the pull-out faucet body to enable the water outlet head 22 to deflect to a preset angle on the pull-out faucet body. The water outlet head 22 and the pull-out tube 21 are connected by a snap-fitting manner, and the guide slope 231 on the outer wall of the connecting cover 23 and the positioning slope 12 on the pull-out faucet body can guide each other, so that the water outlet head 22 can be deflected to a preset angle when returning to the end of the curved pipe 11.

[0030] In this embodiment, the connecting wall 221 is cylindrical, and its bottom is connected to the internal flow channel of the water outlet head 22. When one end of the pull-out tube 21 is inserted into the connecting wall 221, the pull-out tube 21 is in fluid communication with the internal flow channel of the water outlet head 22, enabling water to flow from the water outlet head 22. The pull-out tube 21 also engages with the engaging member 222 of the connecting wall 221, thereby facilitating quick installation of the pull-out tube 21 and the connecting wall 221, without the need for threaded connection.

[0031] The connecting cover 23 can rotate along the engaging groove 2211 to engage with the connecting wall 221. The inner wall of the connecting cover 23 includes a raised portion 232. When the connecting cover 23 rotates to a pressing position, the raised portion 232 corresponds to and presses against the engaging member 222. In this embodiment, a connecting space 233 is formed on the inner wall of the connecting cover 23. The connecting space 233 has a first width dimension and a second width dimension, with the first width dimension being greater than the second width dimension. The raised portion 232 is formed on either side of the second width dimension of the connecting space 233. A locking block 234 is provided on either side of the first width direction of the connecting space 233, and the locking block 234 is connected to the engaging groove 2211. The connecting space 233 is elliptical, oval, or spindle-shaped, with the raised portions 232 formed on the two smaller width sides.

[0032] The coupling groove 2211 includes a first coupling groove 2212 extending axially and a second coupling groove 2213 extending circumferentially, the second coupling groove 2213 is connected to the first coupling groove 2212, and the connecting cover 23 is axially sleeved on the outside of the connecting wall 221 so that the coupling block 234 moves along the first coupling groove 2212 to the corresponding second coupling groove 2213; the connecting cover 23 rotates so that the coupling block 234 moves along the second coupling groove 2213.

[0033] One end of the pulling tube 21 includes a rotatably arranged clamping ring 211, and a clamping block 212 is provided on the clamping ring 211, which can be clamped with the clamping part 222. The inner wall of the connecting wall 221 is formed with a guide groove 2214 corresponding to the clamping part 222, and the lower end of the guide groove 2214 corresponds to the clamping part 222. The upper end of the guide groove 2214 is formed at the upper end of the connecting wall 221, and the width of the guide groove 2214 gradually decreases in the direction from its upper end to its lower end; the clamping block 212 can be guided to the clamping part 222 by the guide groove 2214. The wall of the connecting wall 221 is provided with a through hole 2215. The clamping member 222 further includes a cantilever 2221. One end of the cantilever 2221 is connected to one side of the through hole 2215. The inner side of the cantilever 2221 is recessed relative to the inner wall of the connecting wall 221 to form a clamping hole 2222. The clamping block 212 can be clamped into the clamping hole 2222. The other end of the cantilever 2221 protrudes from the outer wall of the connecting wall 221 to form a protrusion 2223. The protrusion 2223 can be compressed to drive the clamping block 212 out of the clamping hole 2222. The lower end of the clamping block 212 is triangular, and the upper end of the clamping block 212 is an elastic cantilever 2121, which is clamped into the clamping hole 2222.

[0034] During installation, the connection cover 23 can be first attached to the outside of the connection wall 221. The block 234 of the connection cover 23 is first moved along the first slot 2212 to the corresponding second slot 2213. At this point, the connection cover 23 is axially attached to the outside of the connection wall. Subsequently, the connection cover 23 can be rotated until the block 234 engages with the engaging position at the end of the second slot 2213. At this point, the two sides of the connection space 233 corresponding to the first width dimension correspond to the outside of the engaging member 222, and the protrusion 2223 on the cantilever 2221 is not pressed. In this embodiment, there are two engaging slots 2211, two blocks 234, and two engaging members 222, and they are arranged 180 degrees apart.

[0035] One end of the pull-out tube 21 can be inserted into the corresponding connecting wall 221. At this time, the lower end of the clamping ring 211 corresponds to the guide groove 2214. Due to the guiding effect of the guide groove 2214, the clamping ring 211 can rotate relative to the pull-out tube 21. The insertion movement of the pull-out tube 21 can rotate the clamping ring 211 to the clamping hole 2222 corresponding to the lower end of the guide groove 2214, and the installation is completed. The water outlet head 22 can rotate relative to the pull-out tube 21 by means of the clamping ring 211, and the pull-out tube 21 is sealed and connected to the internal flow channel of the water outlet head 22.

[0036] The guide slope 231 on the outer wall of the connecting cover 23 can be positioned with the positioning slope 12 so that the water outlet head 22 has a unique orientation relative to the pull-out faucet body.

[0037] When it is necessary to separate the pull-out tube 21 from the water outlet head 22, it is only necessary to rotate the connecting cover 23 until the block 234 corresponds to the first slot 2212. At this time, the raised parts 232 on both sides of the connecting space 233 corresponding to the first width dimension press against the protrusion 2223 of the cantilever 2221. At this time, the inner side of the cantilever 2221 presses the elastic cantilever 2121, so that the elastic cantilever 2121 leaves the connecting hole 2222. At this time, the pull-out tube 21 can be directly pulled out.

[0038] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
