Description

Technical Field

[0001] This utility model relates to the field of kitchen faucet technology, and in particular to a kitchen faucet with a magnetic suction structure. Background Technology

[0002] In modern kitchen faucet design, magnetic bracket kitchen faucets have gained widespread attention due to their convenience and flexibility. However, existing magnetic bracket kitchen faucets have several shortcomings in practical applications. Current products on the market primarily control the water flow angle using the magnetic force of the magnet itself. This method has significant drawbacks: when the magnetic force is weak, the water flow angle is easily misaligned, failing to achieve the desired water flow effect; while when the magnetic force is too strong, the suction force of the spout is too strong, requiring effort from the user and resulting in a poor user experience. Furthermore, existing products have complex structural designs and numerous parts, increasing manufacturing costs and making subsequent maintenance inconvenient. Additionally, due to sealing issues, the risk of leakage is high. These problems seriously affect the practicality and market competitiveness of the products. Therefore, effectively addressing the shortcomings of magnetic bracket kitchen faucets in terms of water flow angle stability, ease of operation, and cost control has become an urgent technical challenge. This utility model aims to provide a superior, lower-cost, and easier-to-maintain solution by optimizing the magnetic structure design and simplifying the connection method. Utility Model Content

[0003] The purpose of this utility model is to provide a kitchen faucet with a magnetic structure, which solves the problems mentioned in the background art.

[0004] This utility model is implemented as follows: a magnetic kitchen faucet includes a main body, a support body, and a spout. The main body consists of a body, a valve core, a pressure cap, a decorative cover, a handle seat, a handle rod, and related fasteners. The valve core is installed inside the main body, with its bottom surface flush against the side plane of the main body and locked in place by the pressure cap to prevent loosening or leakage. The decorative cover is threadedly locked onto the pressure cap. The handle seat is mounted on the valve core rod and secured with an M5 screw, and the handle rod is threadedly locked onto the handle seat by the M5 screw. Further, the support connector has two O-rings fitted into the O-ring groove and retaining rings installed in the retaining ring groove. The support connector passes through the upper part of the main body and inserts into the inner hole of the main body, and is locked in place by a threaded connection. An anti-wear pad is fitted onto the support head to reduce friction.

[0005] Furthermore, the support component includes a water outlet connector, a support tube, a plastic magnet sleeve, and related fasteners. The water outlet connector has an O-ring installed in the O-ring groove and is threadedly locked to one end of the water outlet hose. The water outlet connector is inserted into the inner hole of the support connector and secured with an M4 screw. The inner cavity of the front end of the support tube is fitted with a plastic magnet sleeve and secured to the support connector with an M5 screw. One end of the rubber tube passes through the water outlet hose and is inserted into the inner hole of the support tube. Specifically, the plastic magnet sleeve contains a magnet with a square groove on its front side for engaging with the protrusion of the water outlet head.

[0006] Specifically, the water outlet portion includes a water outlet head, a hose connector, a plastic clip, and related seals. The hose connector has an O-ring in the O-ring groove and is locked onto the water outlet hose by threads. The hose connector is inserted into the inner hole of the water outlet head and secured therein by the plastic clip. The water outlet head features a square boss with a magnet inside. The boss and the square groove of the plastic magnet sleeve achieve automatic alignment and attraction through the principle of opposite poles attracting. The maximum clearance between the two is 0.15mm, ensuring the stability of the water outlet angle and preventing jumping or detachment due to insufficient magnetic force.

[0007] Furthermore, the magnetic structure in this invention includes a plastic magnet sleeve and a protrusion on the water outlet. The plastic magnet sleeve contains a magnet, with a square groove designed on its front. The square protrusion on the water outlet and the square groove on the plastic magnet sleeve automatically align and attract each other using the principle of magnetic attraction between opposite poles. In particular, the gap between the two is precisely designed to ensure that there will be no jumping or detachment due to insufficient magnetic force during use.

[0008] Specifically, the snap-fit ​​connection structure in this invention uses plastic snap-fits to fix the hose connector in the inner hole of the water outlet. This design simplifies the complexity of traditional threaded connections, reduces the number of parts, lowers production costs, and improves assembly efficiency and ease of after-sales maintenance. The snap-fit ​​connection method also makes operation easier for users, enhancing the user experience.

[0009] Through the above technical solution, this utility model achieves the following technical effects: First, by utilizing the principle of opposite magnetic poles attracting and a gap fit design, the water outlet angle between the outlet head and the support tube is ensured to be stable, avoiding jumping or detachment problems caused by insufficient magnetic force. Second, the use of a plastic magnet sleeve and a snap-fit ​​connection method reduces the number of parts, lowers production costs, and improves assembly efficiency. Third, the snap-fit ​​connection method of the outlet head makes operation easier for users, enhancing the user experience. Finally, the simplified structural design facilitates subsequent product maintenance and reduces the risk of leakage.

[0010] In summary, this utility model solves the problems of unstable water outlet angle, high cost, and inconvenient maintenance in existing magnetic bracket kitchen faucets by designing a plastic magnetic sleeve at the front end of the bracket and combining it with a snap-fit ​​connection for the water outlet. This design not only ensures the functionality and aesthetics of the product but also significantly reduces production costs, improves the user experience, and has a clear competitive advantage in the market.

[0016] This utility model relates to a magnetic kitchen faucet, combined with an attached... Figure 1 To be continued Figure 3 The document also provides a detailed description of the specific implementation method, including the component designations. This implementation method describes the overall structure, assembly process, operating principle, and practical application scenarios of the faucet.

[0017] like Figure 1As shown, the faucet of this utility model consists of a main body, a bracket, and a water outlet. The main body includes a main body 19, a valve core 20, a pressure cap 21, a decorative cover 22, a handle seat 23, a handle rod 25, and related fixing parts. The valve core 20 is installed in the inner cavity 19-1 of the main body 19, with its bottom surface 20-1 flush with the side plane 19-2 of the main body 19 and locked by the pressure cap 21 to prevent loosening or leakage. The decorative cover 22 is locked onto the pressure cap 21 by threads. The handle seat 23 is installed on the valve core rod 20-2 of the valve core 20 and fixed with an M5 screw 24. The handle rod 25 is locked onto the handle seat 23 by threads on the M5 screw 24. The bracket connector 15 has two O-rings 18 fitted in the O-ring groove 15-1, and retaining rings 12 and 13 are installed in the retaining ring grooves 15-2 and 15-3, respectively. The bracket connector 15 passes through the upper part 19-3 of the main body 19 and is inserted into the inner hole 19-4 of the main body 19, and is locked in place by a threaded connection. The anti-abrasion pad 17 is fitted onto the bracket connector 15 to reduce friction and improve durability.

[0018] The support structure includes a water outlet connector 10, a support tube 8, a plastic magnet sleeve 3, and related fasteners. The water outlet connector 10 has an O-ring 11 installed in the O-ring groove 10-1 and is threadedly locked to one end 7-1 of the water outlet hose 7. The water outlet connector 10 is inserted into the inner hole 15-6 of the support connector 15 and secured with an M4 screw 16, ensuring that the water outlet connector 10 will not detach from the inner hole of the support connector 15 or loosen, causing leakage. The inner cavity of the front end 8-1 of the support tube 8 is fitted with a plastic magnet sleeve 3, which contains a magnet 3-1. A square groove 3-2 is designed on its front side. The support tube 8 passes through the water outlet hose 7 and is then mounted on the support connector 15, secured with an M5 screw 9. One end of the rubber tube 6 passes through the water outlet hose 7 and is inserted into the inner hole 8-3 of the support tube 8, forming a complete water flow channel.

[0019] The water outlet section includes a water outlet head 1, a hose connector 5, a plastic clip 2, and related seals. The hose connector 5 has an O-ring 4 installed in the O-ring groove 5-1 and is locked to one end 7-2 of the water outlet hose 7 by threads. The hose connector 5 is inserted into the inner hole 1-1 of the water outlet head 1 and secured by the plastic clip 2. The water outlet head 1 is designed with a square boss 1-3, which encloses a magnet 1-3-1 for engaging with the square groove 3-2 of the plastic magnet sleeve 3. The clips on both sides of the plastic clip 2 are inserted into the groove 5-2 of the hose connector 5, firmly fixing the hose connector 5 in the inner hole of the water outlet head 1. The maximum clearance between the water outlet head 1 and the support tube 8 is 0.15mm, ensuring stability during use and preventing jumping or detachment due to insufficient magnetic force.

[0020] The core technology of this invention lies in the design of the magnetic attraction structure. The magnet 3-1 inside the plastic magnetic sleeve 3 and the magnet 1-3-1 inside the water outlet head 1 generate attraction through the principle of opposite poles attracting. When the water outlet head 1 approaches the front end of the support tube 8, the square protrusion 1-3 of the water outlet head 1 automatically aligns and is drawn into the square groove 3-2 of the plastic magnetic sleeve 3. Simultaneously, under the guidance of the magnetic force and the groove, the outer surface of the water outlet head 1 automatically flattens against the arc-shaped surface of the plastic magnetic sleeve 3, maintaining perpendicularity to the product. This design not only ensures the stability of the water outlet angle but also solves the problem of jumping or falling off caused by insufficient magnetic force in traditional magnetic faucets.

[0021] In practical applications, users only need to bring the water outlet 1 close to the front end of the support tube 8 to complete the adsorption operation. Due to the snap-fit ​​connection, the hose connector 5 can be quickly fixed in the inner hole of the water outlet 1, simplifying the complexity of traditional threaded connections. Users can disassemble and assemble without additional tools, improving ease of operation and user experience. Furthermore, the design of the plastic magnet sleeve 3 makes the magnet smaller, further reducing production costs, while also reducing the number of parts, improving assembly efficiency and the convenience of after-sales maintenance.

[0022] The entire faucet's operating process is as follows: S1 After the water source is turned on, the water flows through the main body 19 into the bracket connector 15, and then through the outlet connector 10 into the outlet hose 7. S2 The water flows through the hose connector 5 into the outlet head 1 and is sprayed out through the outlet head 1. S3 The user can adjust the position of the outlet head 1 as needed and attach it to the plastic magnet sleeve 3 at the front end of the bracket tube 8. S4 When it is necessary to disassemble or replace the outlet head 1, the user only needs to apply a little force to remove the outlet head 1 from the plastic magnet sleeve 3, and then quickly disassemble the hose connector 5 through the plastic clip 2. S5 When reinstalling, insert the hose connector 5 into the inner hole of the outlet head 1 and fix it with the plastic clip 2, and then bring the outlet head 1 close to the front end of the bracket tube 8 to complete the attachment.

[0023] The advantages of this invention are multifaceted. First, by utilizing the principle of magnetic attraction between opposite poles and a gap-fit ​​design, the water outlet angle between the spout 1 and the support tube 8 is ensured to be stable, avoiding the jumping or detachment problems caused by insufficient magnetic force in traditional magnetic faucets. Second, the application of the plastic magnet sleeve 3 and the snap-fit ​​connection method reduces the number of parts, lowers production costs, and improves assembly efficiency. Third, the snap-fit ​​connection method of the spout 1 makes operation easier for users, enhancing the user experience. Finally, the simplified structural design facilitates subsequent product maintenance and reduces the risk of leakage.

[0024] In practical applications, this invention is suitable for home kitchens, restaurant kitchens, and other places requiring efficient faucet operation. For example, in a home kitchen, users can easily adjust the position of the water outlet 1 to meet different washing needs; in a restaurant kitchen, chefs can quickly disassemble and replace the water outlet 1 to adapt to different cleaning tasks. Furthermore, due to its lower production and maintenance costs, this invention has a significant competitive advantage for large-scale production and sales.

[0025] In summary, this utility model solves the problems of unstable water outlet angle, high cost, and inconvenient maintenance in existing magnetic bracket kitchen faucets by designing a plastic magnet sleeve 3 at the front end of the bracket and combining it with the snap-fit ​​connection of the water outlet head 1. This design not only ensures the functionality and aesthetics of the product but also significantly reduces production costs, improves the user experience, and has a clear competitive advantage in the market.
