Description

Technical Field

[0001] This application belongs to the field of kitchen and bathroom equipment, and in particular relates to a silicone kitchen faucet. Background Technology

[0002] Traditional kitchen faucets, especially pull-out or swivel faucets with handheld showerheads, suffer from a core problem: critical connection points (such as the showerhead latch and swivel support) experience significant mechanical stress and wear due to frequent insertion and removal, rotation, and water flow impact. This generally results in a short lifespan, causing users to face frequent repairs or replacements, leading to inconvenience and financial burdens. Therefore, it is necessary to solve these technical problems. Utility Model Content

[0003] The purpose of this application is to provide a silicone kitchen faucet to solve the technical problem of short service life of kitchen faucets in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide a silicone kitchen faucet, comprising:

[0005] The main body forms a movable handheld nozzle;

[0006] A bracket is attached to the main body and forms a snap-fit ​​portion at one end away from the main body, the snap-fit ​​portion forming an inner cavity with a constant C-shaped cross-section;

[0007] A ferrule is detachably snapped into the inner cavity and forms a bayonet for snapping into the handheld nozzle. The ferrule also forms flange edges at both ends of the bayonet in the axial direction. The flange edges, the snap-fit ​​portion forming the sidewall of the inner cavity, and the sidewall of the ferrule forming the bayonet together constitute a buffer cavity. The handheld nozzle forms a snap-fit ​​groove for snapping into the bayonet, and the flange edge abuts against the sidewall of the snap-fit ​​groove.

[0008] Optionally, a countersunk surface is formed on the bracket to accommodate the flange edge so that the flange edge is flush with the end face of the bracket in the axial direction of the inner cavity.

[0009] Optionally, a longitudinal groove communicating with the inner cavity is formed on the support;

[0010] The longitudinal groove extends in a direction parallel to the axial direction of the inner cavity, and a snap-fit ​​strip is formed on the sleeve that can be detachably snapped into the longitudinal groove.

[0011] Optionally, a rounded corner is formed on the sidewall of the longitudinal groove near the opening of the inner cavity to facilitate the insertion of the snap-fit ​​strip into the longitudinal groove.

[0012] Optionally, the sleeve is a silicone material.

[0013] Optionally, the main body is connected to a water inlet pipe, a silicone inner tube, and a protective tube fitted on the silicone inner tube. The silicone kitchen faucet also includes a rotating body coaxially connected to the end of the protective tube and through which the silicone inner tube passes.

[0014] The water inlet pipe and the silicone inner tube are sealed and connected. The rotating body is rotatably mounted on the main body and can rotate around its own central axis. The bracket is connected to the protective tube.

[0015] Optionally, a coaxial annular groove is formed on the rotating body, and the silicone kitchen faucet further includes an open retaining ring that can be detachably snapped into the annular groove;

[0016] The open retaining ring is disposed inside the main body and a positioning hole perpendicular to its own axis is formed on the open retaining ring. The main body is provided with a through threaded hole, which is coaxially corresponding to the positioning hole. The silicone kitchen faucet also includes screws that can be installed simultaneously in the threaded hole and the positioning hole.

[0017] Optionally, the silicone kitchen faucet may also include several slip rings;

[0018] The slip ring is disposed between the rotating body and the main body, and between the support and the main body, so that the rotating body and the support can rotate smoothly relative to the main body.

[0019] Optionally, a plurality of sealing rings are coaxially fitted on the rotating body;

[0020] The rotating body is sealed to the main body via the sealing ring.

[0021] The beneficial effects of the silicone kitchen faucet provided in this application are as follows: Compared with the prior art, in the silicone kitchen faucet provided in this application, since the flange edges at both ends of the sleeve and the side wall of the bracket locking part cooperate to form a buffer cavity, the elastic deformation of the sleeve caused by the impact of the handheld spray head when it is hooked into the slot can be absorbed by the buffer cavity. This avoids the impact energy being directly transmitted to the locking part, thereby preventing the locking part from bearing repeated impact stress, and fundamentally eliminating the risk of fatigue fracture or plastic deformation caused by stress concentration in the locking part. Therefore, the silicone kitchen faucet provided in this application can achieve a longer service life, which is far superior to the prior art. Attached Figure Description

[0037] Please refer to the following: Figures 1 to 9 The present application provides a description of a silicone kitchen faucet according to an embodiment. The silicone kitchen faucet includes a main body 100, a bracket 200, and a retaining sleeve 300. Wherein:

[0038] The main body 100 forms a movable handheld nozzle 101; the bracket 200 is connected to the main body 100 and forms a snap-fit ​​part 201 at one end away from the main body 100, the snap-fit ​​part 201 forms an inner cavity 202 with a constant C-shaped cross section; the sleeve 300 is detachably snapped into the inner cavity 202 and forms a slot 301 for snapping the handheld nozzle 101, the sleeve 300 also forms flange edges 302 at both ends of the slot 301 in the axial direction, the flange edges 302, the snap-fit ​​part 201 form the side wall of the inner cavity 202 and the sleeve 300 form the side wall of the slot 301 together to form a buffer cavity 303, the handheld nozzle 101 forms a snap-fit ​​groove 102 for snapping into the slot 301 and the flange edge 302 is used to abut against the side wall of the snap-fit ​​groove 102.

[0039] According to the structure provided in this embodiment, in the silicone kitchen faucet provided in this embodiment, since the flange edges 302 at both ends of the sleeve 300 and the side wall of the snap-fit ​​portion 201 of the bracket 200 cooperate to form a buffer cavity 303, the elastic deformation of the sleeve 300 caused by the impact of the handheld spray head 101 when it is hooked into the slot 301 can be absorbed by the buffer cavity 303. This avoids the impact energy being directly transmitted to the snap-fit ​​portion 201, thereby preventing the snap-fit ​​portion 201 from bearing repeated impact stress. This fundamentally eliminates the risk of fatigue fracture or plastic deformation of the snap-fit ​​portion 201 due to stress concentration. On the other hand, the sleeve 300 has an easily replaceable structure; after damage, only the sleeve 300 needs to be replaced, which helps to save on usage costs. Therefore, the silicone kitchen faucet provided in this embodiment can achieve a longer service life, which is far superior to the prior art.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9 A recessed platform 203 is formed on the bracket 200 to accommodate the flange edge 302, so that the flange edge 302 is flush with the end face of the bracket 200 in the axial direction of the inner cavity 202. According to the structure provided in this embodiment, the recessed platform 203 can provide uniform axial support constraint for the flange edge 302, eliminating the stress concentration caused by the flange edge 302 being suspended, and can also effectively prevent the flange edge 302 from being accidentally touched by users, which is also conducive to further extending the service life of the silicone kitchen faucet in this embodiment.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9 A longitudinal groove 204 communicating with the inner cavity 202 is formed on the bracket 200; the longitudinal groove 204 extends in a direction parallel to the axial direction of the inner cavity 202, and a snap-fit ​​strip 304 is formed on the sleeve 300 that can be detachably snapped into the longitudinal groove 204. In this embodiment, multiple longitudinal grooves 204 can be provided around the central axis of the inner cavity 202. According to the structure provided in this embodiment, the snap-fit ​​strip 304 can form a circumferential elastic snap-fit ​​lock by embedding in the longitudinal groove 204. In this way, when the sleeve 300 undergoes elastic deformation in the buffer cavity 303, it can always maintain the preset radial orientation, completely eliminating the risk of circumferential displacement of the sleeve 300 caused by water flow impact or nozzle shaking, thereby ensuring the uniformity of deformation of the buffer cavity 303 in all directions, avoiding local stress concentration caused by the deflection of the sleeve 300, and effectively preventing the sleeve 300 from falling off the inner cavity 202 by cooperating with the flange edge 302. This also helps to further extend the service life of the silicone kitchen faucet in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9A rounded corner 205 is formed on the side wall of the longitudinal groove 204 near the opening of the inner cavity 202 to facilitate the insertion of the snap-fit ​​strip 304 into the longitudinal groove 204. According to the structure provided in this embodiment, the rounded corner 205 structure at the inlet side wall of the longitudinal groove 204 can effectively eliminate the rigid collision between the snap-fit ​​strip 304 and the edge of the longitudinal groove 204 during assembly, and avoid tearing damage caused by stress concentration at the root of the snap-fit ​​strip 304. This also helps to further extend the service life of the silicone kitchen faucet in this embodiment.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9 The sleeve 300 is made of silicone. According to the structure provided in this embodiment, the silicone sleeve 300 has better elastic deformation capability and can completely solve the failure problem of traditional materials becoming brittle and cracking in humid environments. This also helps to further extend the service life of the silicone kitchen faucet in this embodiment.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9 The main body 100 is connected to a water inlet pipe 103, a silicone inner tube 104, and a protective tube 105 fitted onto the silicone inner tube 104. The silicone kitchen faucet also includes a rotating body 106 coaxially connected to the end of the protective tube 105 and through which the silicone inner tube 104 passes. The water inlet pipe 103 and the silicone inner tube 104 are sealed and connected. The rotating body 106 is rotatably mounted on the main body 100 and can rotate around its own central axis. A bracket 200 is connected to the protective tube 105. In this embodiment, the silicone inner tube 104 can be used to deliver water in conjunction with the water inlet pipe 103, while the protective tube 105 provides good protection for the silicone inner tube 104. According to the structure provided in this embodiment, the rotating body 106 allows the protective tube 105 to rotate smoothly relative to the main body 100. This not only makes the silicone kitchen faucet in this embodiment more flexible to use but also helps to further extend its service life.

[0045] Key references Figure 9 Here, it is understandable that the bracket 200 forms an annular connecting part 206 at one end near the main body 100. At least one section of the inner wall of the annular connecting part 206 has an internal thread that engages with the corresponding external thread on the rotating body 106, thereby connecting the bracket 200 and the rotating body 106 as one unit. At least one section of the protective tube 105 passes through the annular connecting part 206 and extends into the rotating body 106, and is fixedly connected to the rotating body 106 (existing kitchen faucet connection technology can be used). The front end of the silicone inner tube 104 is usually provided with a connector and a sealing ring 500 is fitted on the connector. The connector of the silicone inner tube 104 is sealed with the corresponding inner cavity on the main body 100 through the sealing ring 500 and can be rotatably engaged. In this way, the silicone inner tube 104 can rotate smoothly with the rotating body 106, the protective tube 105, and the bracket 200, which is convenient to use.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9 The rotating body 106 has a coaxial annular groove 107. The silicone kitchen faucet also includes an open retaining ring 108 that can be detachably snapped into the annular groove 107. The open retaining ring 108 is disposed inside the main body 100 and has a positioning hole 109 perpendicular to its own axis. The main body 100 has a through threaded hole 110, which is coaxially corresponding to the positioning hole 109. The silicone kitchen faucet also includes a screw 111 that can be simultaneously installed in the threaded hole 110 and the positioning hole 109. According to the structure provided in this embodiment, the open retaining ring 108 connected to the main body 100 by the screw 111 cooperating with the threaded hole 110 and the positioning hole 109 can not only allow the rotating body 106 to rotate smoothly around its own central axis, but also effectively prevent it from moving along the axial direction. This also helps to further extend the service life of the silicone kitchen faucet in this embodiment.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9 The silicone kitchen faucet also includes several slip rings 400; the slip rings 400 are disposed between the rotating body 106 and the main body 100, and between the annular connecting portion 206 of the bracket 200 and the main body 100, so that the bracket 200 and the protective tube 105 can rotate smoothly relative to the main body 100. According to the structure provided in this embodiment, the slip rings 400 can significantly reduce the frictional loss between the rotating body 106 and the bracket 200 and the main body 100, which also helps to further extend the service life of the silicone kitchen faucet in this embodiment.

[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 9 A plurality of sealing rings 500 are coaxially fitted on the rotating body 106; the rotating body 106 is sealed to the main body 100 through the sealing rings 500. According to the structure provided in this embodiment, the sealing rings 500 fitted on the rotating body 106 can effectively prevent water from leaking from the gap between the rotating body 106 and the main body 100, which also helps to further extend the service life of the silicone kitchen faucet in this embodiment.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
