Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and in particular to a faucet with a side spray arm. Background Technology

[0002] Dual-outlet faucets are common in daily life. They consist of a main spout located at the top of the faucet body and a side spray arm. The side spray arm allows for cleaning through its spout holes, making the faucet more versatile and improving the user experience. However, in current technology, multi-outlet faucets typically use the faucet body's internal cavity as the water path. When the faucet is turned off, due to its large size, a significant amount of water remains inside. This water, under gravity, flows out from the side spray arm's spout holes. This not only wastes water but can also wet countertops or floors, causing inconvenience. Especially in kitchens, residual water may drip onto prepared food, affecting hygiene. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a faucet with a side spray arm. By optimizing the water circuit design, the faucet body is provided with an independent water outlet pipe that is connected to the side spray arm. The independent water outlet pipe has less water accumulation inside, which can effectively prevent water leakage from the water outlet of the side spray arm.

[0004] The technical solution of this utility model is as follows: A faucet with a side spray arm, comprising a faucet body, a water outlet faucet, and a side spray arm, wherein the water outlet faucet is located at the top of the faucet body, and the side spray arm is located on the side of the faucet body. A switching valve assembly is provided on the faucet body, which is connected to the cold water inlet pipe, the hot water inlet pipe, the faucet outlet pipe and the side spray outlet pipe respectively; The faucet body includes an inner tube and an outer tube, which cooperate to form a gap chamber. The inner wall of the inner tube is provided with a side spray water inlet end. The side spray water inlet end is connected to the side spray arm through the gap chamber. The side spray water outlet pipe is connected to the side spray water inlet end. The faucet water outlet pipe is connected to the faucet. Both the side spray water outlet pipe and the faucet water outlet pipe are inserted into the faucet body. The switching valve assembly includes a temperature regulating valve core and a water path switching valve core. The faucet body is equipped with a temperature regulating handwheel and a switching handwheel. The temperature regulating handwheel can drive the temperature regulating valve core to rotate to control the water outlet temperature; the switching handwheel can drive the water path switching valve core to rotate to switch the water outlet path.

[0005] Using the above technical solution, the temperature-adjusting handwheel and temperature-adjusting valve core work together to precisely adjust the water temperature, meeting the needs of different usage scenarios; the switching handwheel and water circuit switching valve core are linked to quickly switch between the faucet and side spray arm functions, improving ease of use. The water outlet path for the top faucet is: switching valve assembly → faucet outlet pipe → faucet; the water outlet path for the side spray arm is: switching valve assembly → side spray outlet pipe → side spray inlet → gap chamber → side spray arm.

[0006] Through a sophisticated water circuit optimization design, this faucet cleverly incorporates independent faucet outlet pipes and side spray outlet pipes within its body. The faucet outlet pipe is directly connected to the faucet itself, while the side spray outlet pipe is directly connected to the side spray arm. By replacing the water accumulation inside the faucet body with the outlet pipes, the small internal space of the outlet pipes reduces water accumulation and effectively prevents leakage from the outlet holes on the side spray arm, thus improving the user experience and product reliability.

[0007] A further feature of this invention is as follows: the faucet body includes a lower pipe, a main pipe, and a top pipe. The main pipe and the lower pipe are respectively located at the upper and lower ends of the inner pipe. The outer pipe has a side connector on its side. The side spray arm is mounted on the side connector. The main pipe has an assembly head on its side. The switching valve assembly is installed inside the assembly head. The temperature control handwheel and the switching handwheel are operably located on the assembly head. The top pipe is mounted on the main pipe. The water faucet is located on the top pipe.

[0008] By further modifying the design of the faucet body into a structure consisting of a lower pipe, a main pipe, and a top pipe, the overall structure becomes more rational, and the installation and disassembly of each component are facilitated. The side connector on the outer pipe facilitates the installation of the side spray arm, allowing for flexible mounting. The assembly head on the side of the main pipe provides space for the installation of the switching valve assembly, while the temperature control handwheel and switching handwheel are operably located on the assembly head, allowing users to easily adjust the temperature and switch the water flow mode.

[0009] A further feature of this invention is that the temperature control handwheel has an inner hole in the middle, and the inner hole wall has internal teeth. The temperature control valve core has external teeth on its outer periphery. The temperature control valve core is coaxially arranged in the inner hole of the temperature control handwheel and achieves synchronous rotation through the meshing of the internal and external teeth.

[0010] By further modifying the above-mentioned design, an inner hole is created in the center of the temperature-regulating handwheel, with internal teeth designed on the inner hole wall. Simultaneously, external teeth are provided on the outer periphery of the temperature-regulating valve core. This allows the temperature-regulating valve core to be coaxially positioned within the inner hole of the handwheel. This design utilizes the meshing of the internal and external teeth to achieve synchronous rotation of the handwheel and the valve core. When the user rotates the handwheel, the valve core rotates synchronously, thereby precisely controlling the outlet water temperature and providing the user with a more convenient and accurate operating experience.

[0011] A further feature of this invention is as follows: the water circuit switching valve core is provided with a shaft head, and the inner side of the end face of the switching handwheel is provided with a shaft hole. The shaft head is inserted into the shaft hole and abuts against it through a limiting plane. The end face of the switching handwheel is fixedly connected to the shaft head by screws. The switching handwheel is located on the outer end side of the assembly head, and the temperature adjustment handwheel abuts against the end face of the assembly head.

[0012] By further configuring the above-mentioned design, the switching handwheel is positioned on the outer end of the assembly head, and a shaft head is provided on the water circuit switching valve core. A shaft hole is also provided on the inner end face of the switching handwheel. The shaft hole fits over the shaft head and engages with a limiting plane, allowing both to rotate synchronously. Screws are used to further secure the handwheel to the water circuit switching valve core. Simultaneously, the temperature control handwheel rests between the switching handwheel and the end face of the assembly head. This structural layout not only optimizes space utilization but also ensures a stable connection between all components. When the user operates the switching handwheel, the water circuit switching valve core moves synchronously, enabling rapid water circuit switching. The abutting design of the temperature control handwheel further enhances the overall structural stability and ease of operation, providing users with a smoother and more reliable user experience.

[0013] A further feature of this invention is that an anti-wear ring A is provided between the temperature control handwheel and the outer stepped surface A of the assembly head, and an anti-wear ring B is provided between the switching handwheel and the outer stepped surface B of the temperature control handwheel.

[0014] By further configuring the components as described above, and by installing anti-wear ring A between the temperature control handwheel and the outer surface A of the assembly head, and anti-wear ring B between the switching handwheel and the outer surface B of the temperature control handwheel, friction and wear between components are effectively reduced, and the durability of the components is improved. At the same time, the anti-wear rings also further enhance the sealing between the components, prevent water leakage, and improve the overall performance of the product.

[0015] A further feature of this invention is that the switching handwheel is located outside the temperature control handwheel, a lever is provided on the outer periphery of the temperature control handwheel, and anti-slip texture is provided on the outer periphery of the switching handwheel.

[0016] With the above-mentioned further design, by placing the switching handwheel on the outside of the temperature control handwheel, users can quickly locate and operate the corresponding handwheel according to their needs, improving ease of use. A lever is provided on the outer periphery of the temperature control handwheel, allowing users to more precisely control the rotation angle of the handwheel and achieve accurate water temperature adjustment. Furthermore, anti-slip textures are provided on the outer periphery of the switching handwheel to prevent slippage during operation.

[0017] A further feature of this invention is that the water tap is a pull-out tap.

[0018] By further modifying the faucet to a pull-out design, the range of uses and flexibility of the faucet are greatly expanded. Users can easily pull the faucet out to different positions and angles according to their actual needs, making it convenient to clean or fill water in various hard-to-reach areas, such as the corners of the kitchen sink or the corners of the bathroom.

The top pipe 160 is installed on the main pipe 150, and the water outlet faucet 200 is located on the top pipe 160. The top pipe 160, the main pipe 150, the inner pipe 110, and the lower pipe 140 are integrally formed or separately connected by threads. The inner pipe and the outer pipe are integrally formed or separately connected by threads.

[0022] The switching valve assembly 400 includes a temperature regulating valve core 401 and a water path switching valve core 402. The faucet body 100 is provided with a temperature regulating handwheel 500 and a switching handwheel 600. The temperature regulating handwheel 500 can drive the temperature regulating valve core 401 to rotate to control the outlet water temperature. The switching handwheel 600 can drive the water path switching valve core 402 to rotate to switch the outlet water path. The adjustment by the handwheel driving the valve core is a conventional design. The specific structure of the adjustment by the valve core will not be described in detail. The main improvement is in the installation of the handwheel. The temperature regulating handwheel 500 and the switching handwheel 600 are operably set on the assembly head 151. The temperature control handwheel 500 has an inner hole 510 in the middle, and the inner hole 510 has internal teeth 511 on the hole wall. The temperature control valve core 401 has external teeth 401a on its outer periphery. The temperature control valve core 401 is coaxially arranged in the inner hole 510 of the temperature control handwheel 500 and achieves synchronous rotation through the meshing of the internal teeth 511 and the external teeth 401a. The switching handwheel 600 is located on the outer end of the assembly head 151. A shaft head 4021 is provided on the water circuit switching valve core 402. A shaft hole 601 is provided on the inner side of the end face of the switching handwheel 600. The shaft head 4021 is inserted into the shaft hole 601 and engages with it through a limiting plane A. Limiting planes A are provided on the outer periphery of the shaft head 4021 and the inner wall of the shaft hole 601. The end face of the switching handwheel 600 is fixedly connected to the shaft head 4021 by screws 610. The temperature regulating handwheel 500 abuts against the end face of the switching handwheel 600 and the assembly head 151. An anti-wear ring A700 is provided between the temperature regulating handwheel 500 and the outer stepped surface A151a of the assembly head 151, and an anti-wear ring B800 is provided between the switching handwheel 600 and the outer stepped surface B520 of the temperature regulating handwheel 500. The switching handwheel 600 is located outside the temperature control handwheel 500. The temperature control handwheel 500 has a toggle block 530 on its outer periphery, and the switching handwheel 600 has anti-slip texture 620 on its outer periphery.

[0023] The internal pipe connection of the faucet of this utility model is as follows: the faucet outlet pipe 430 passes through the inside of the main pipe 150 and the top pipe 160, so that its lower end is connected to the faucet outlet of the switching valve assembly 400 and its upper end is connected to the faucet 200; the side spray outlet pipe 440 passes through the inside of the main pipe 150, so that one end is connected to the side spray outlet of the switching valve assembly 400 and the other end is connected to the side spray inlet 111 on the inner pipe 110; the side spray arm 300 is installed on the side connector 121 of the outer pipe 120, at which time the side spray arm 300 is connected to the gap chamber 130.

[0024] When using the faucet of this utility model, First, by rotating the temperature control handwheel 500, the internal teeth 511 on the inner wall of the inner hole 510 of the temperature control handwheel 500 mesh with the external teeth 401a on the outer periphery of the temperature control valve core 401, thereby driving the temperature control valve core 401 to rotate, thereby adjusting the mixing ratio of cold water and hot water entering the faucet, so as to control the outlet water temperature. When it is necessary to switch the water outlet path, the user rotates the switching handwheel 600. Since the shaft hole 601 on the inner side of the end face of the switching handwheel 600 abuts against the shaft head 4021 on the water circuit switching valve core 402 through the limiting plane A and is fixedly connected by screws 610, rotating the switching handwheel 600 will drive the water circuit switching valve core 402 to rotate. After the water circuit switching valve core 402 rotates, it will cause the water flow direction to change. When switching to the top faucet water outlet mode, the water flows from the cold water inlet pipe 410 and the hot water inlet pipe 420. After passing through the switching valve assembly 400, the water flows out from the faucet outlet pipe 430 and then out through the faucet 200. When switching to the side spray mode, the water enters from the cold water inlet pipe 410 and the hot water inlet pipe 420, passes through the switching valve assembly 400 and flows out from the side spray outlet pipe 440. The water from the side spray outlet pipe 440 enters the gap chamber 130 from the side spray inlet end 111 on the inner pipe 110, then reaches the side spray arm 300 through the gap chamber 130, and finally sprays out from the multiple outlet holes on the side spray arm 300.
