[0001] This utility model relates to the field of kitchen and bathroom appliances, specifically a kitchen faucet. Background Technology

[0002] Kitchen pull-out faucets, also known as drawer faucets, are gaining increasing market share in the kitchenware market. They achieve functions such as pull-out and gravity-assisted retraction of the spray head through a built-in hose and counterweight system.

[0003] The existing faucet nozzles are subjected to continuous force due to the pull of a weight after being extended, making it impossible to lock the position after being pulled out. When users hold items with one hand to rinse, they need to keep pulling the nozzle with the other hand, which is tiring to operate. In addition, there is no angle locking function. When washing the face or rinsing the mouth after meals, users need to manually keep the nozzle pulled out while maintaining the nozzle angle, which causes inconvenience to use. Utility Model Content

[0004] To address the above problems, this utility model provides a kitchen faucet.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a kitchen faucet, comprising a valve seat and a bent pipe mounted on the top of the valve seat. The valve seat has a switch. A flexible hose penetrates the bent pipe and valve seat. One end of the flexible hose is connected to the valve seat at its bottom outer side, and the other end extends out of the bent pipe and is connected to a spray head. A counterweight is fixed to the flexible hose at the bottom of the valve seat to apply a downward pulling force to the flexible hose inside the bent pipe. A limiting structure is provided at the end of the bent pipe for engaging with the flexible hose and the spray head. The end of the bent pipe has a pipe end base tube, and an eccentric base is fixed to the bottom of the pipe end base tube. The eccentric base has an inner cavity that extends from the inner cavity of the pipe end base tube. An operating ring is nested on the eccentric base. The operating ring is a limiting structure, and a buckle is provided at the bottom of the operating ring. Several protruding corrugated rings are provided on the flexible hose. The operating ring rotates on the eccentric base to engage the buckle with the corrugated rings.

[0006] Furthermore, the diameter of the eccentric base is larger than the diameter of the end pipe, and the axis of the eccentric base is not collinear with the axis of the end pipe.

[0007] Furthermore, the buckle is horizontally positioned at the bottom of the operating ring, and the buckle moves to the lower part of the eccentric base cavity by rotating the operating ring; the minimum distance between the outer end of the buckle and the inner wall opposite to the end of the tube is greater than the sum of the hose diameter and the thickness of the single-sided corrugated ring, but less than the sum of the hose diameter and the thickness of the two corrugated rings.

[0008] Furthermore, the operating ring is provided with a side frame on its outer side, the side frame having an inclined structural wall, the structural wall being flat, and the nozzle being provided with a fastener, the fastener having a recessed fastening groove for inserting and fastening onto the structural wall.

[0009] Furthermore, the axis of the end base pipe is vertical, the angle between the structural wall and the axis of the end base pipe is in the range of 30°-60°, and the fastener is provided with a fastening groove whose depth direction is parallel to the direction of the nozzle axis.

[0010] Furthermore, the fastener extends laterally from the nozzle and the top surface of the nozzle is in contact with the bottom of the operating ring.

[0011] Furthermore, the nozzle tip has a surrounding portion that extends upward from the connection point between the hose and the nozzle. The fastener is mounted on the surrounding portion, and the surrounding portion has an open clearance opening on the other side of the fastener. The width of the clearance opening is greater than the diameter of the hose, and the depth of the clearance opening is greater than the radius of the hose.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention features an eccentric base and an operating ring at the end of the bend. When the hose is extended, rotating the operating ring causes the buckle to engage with the corrugated ring of the hose, using mechanical engagement to resist the pull-back force of the counterweight and lock the extension length. Furthermore, the nozzle has a buckle seat that engages with the multi-position buckle slot on the side frame, allowing the nozzle to be used at the desired angle, making it more convenient to use.

[0014] Furthermore, the length locking and angle adjustment functions of this invention operate independently without interfering with each other. When the rotating operating ring releases the latch, the nozzle can still maintain the set angle, improving the convenience and stability of kitchen washing and cleaning. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] Examples, such as Figures 1-4 As shown: This utility model provides a kitchen faucet, the structure of which includes a valve seat 1 and a bent pipe 3 installed at the top of the valve seat 1. A switch 2 is provided on the valve seat 1 to control the opening or closing of the valve seat 1. The inside of the valve seat 1 is a valve body that controls the inflow and outflow of water. A flexible hose 5 penetrates the bent pipe 3 and the valve seat 1. One end of the flexible hose 5 is connected to the valve seat 1 at the bottom outside the valve seat 1. In the prior art, one side of the valve seat 1 is open to allow the flexible hose 5 to pass through. The flexible hose 5 hangs down from the connection end with the valve seat 1, and then the other end of the flexible hose 5 passes upward through the open area on one side of the valve seat 1. The hose 5 enters the bend 3, and the other end of the hose extends out of the bend 3 and is connected to the nozzle 4. A counterweight is fixed on the hose 5 at the bottom of the valve seat 1 to apply a downward pulling force to the hose 5 inside the bend 3, so that the nozzle 4 is pulled back to the end of the bend 3 and kept stable. When in use, the nozzle 4 can be pulled out with the hose 5. However, the nozzle 4 in the prior art does not have a fixed length structure or a fixed angle structure after being pulled out, which is inconvenient when in use. Therefore, in this embodiment, the end of the bend 3 is provided with a limiting structure for fastening with the hose 5 and the nozzle 4.

[0023] The end of the bend 3 has a tube end base 31, which has an inner cavity and is a downward extension of the end of the bend 3. An eccentric base 32 is fixedly provided at the bottom of the tube end base 31. The eccentric base 32 has an inner cavity and is an extension of the inner cavity of the tube end base 31. That is, the eccentric base 32 and the tube end base 31 share a cylindrical inner cavity. An operating ring 33 is nested on the eccentric base 32. The operating ring 33 is a limiting structure. A buckle 34 is provided at the bottom of the operating ring 33. At the same time, the hose 5 is provided with several protruding corrugated rings 51. In this embodiment, the hose 5 is a corrugated pipe. The operating ring 33 rotates on the eccentric base 32 to move the buckle 34, which was originally on the side, to the position where it engages with the corrugated ring 51.

[0024] Specifically, the diameter of the eccentric base 32 is larger than the diameter of the end base pipe 31, and the axis of the eccentric base 32 is not collinear with the axis of the end base pipe 31. In this embodiment, one side of the eccentric base 32 is in contact with the end base pipe 31, that is, the projection of the two on the horizontal plane is two internally tangent circular structures. The buckle 34 is horizontally arranged at the bottom of the operating ring 33. When not in use, the buckle 34 rotates to the side from the position where the eccentric base 32 is tangent to the end base pipe 31, until the buckle 34 does not interfere with the inner cavity of the eccentric base 32. When needed, the buckle 34 moves to the bottom of the inner cavity of the eccentric base 32 by rotating the operating ring 33.

[0025] It should be noted that the minimum distance between the outer end of the buckle 34 and the inner wall of the opposite side of the end base pipe 31 is greater than the sum of the diameter of the hose 5 and the thickness of the single-sided corrugated ring 51, but less than the sum of the diameter of the hose 5 and the thickness of the corrugated rings 51 on both sides. This ensures that after the buckle 34 is rotated to the working position, it can cooperate with the inner wall of the opposite side of the end base pipe 31 to lock the hose 5, but at the same time, it will not jam the hose 5, that is, it will not apply pressure perpendicular to the axial direction to the hose 5. This forms the function of controlling the extension length of the nozzle 4.

[0026] In this embodiment, a side frame 35 is provided on the outside of the operating ring 33. The side frame 35 can be used as a handle for the operating ring 33 to assist in rotating the operating ring 33. The side frame 35 has an inclined structural wall, which is flat. The buckle 42 is provided with a recessed buckle groove 43 for inserting and fastening to the structural wall. It should be noted that the buckle 42 extends laterally from the nozzle 4 and the top surface of the nozzle 4 is in contact with the bottom of the operating ring 33 to avoid the buckle 42 affecting the state of the nozzle 4 when it is not in use.

[0027] It should be noted that the axis of the end base pipe 31 is vertical, and the angle between the structural wall and the axis of the end base pipe 31 is in the range of 30°-60°. In this embodiment, the angle between the structural wall and the axis of the end base pipe 31 is 30°. The nozzle 4 is provided with a fastening seat 42, and the fastening seat 42 of the foundation is provided with a fastening groove 43 whose depth direction is parallel to the axis direction of the nozzle 4, so that the nozzle 4 can be engaged on the side frame 35 at a position with an angle of 30° to the vertical axis. In this embodiment, not only that, the fastening seat 42 is provided with several fastening grooves 43 so that the nozzle 4 can have multiple installation angles.

[0028] In this embodiment, the nozzle 4 has a surrounding portion at its top. The surrounding portion extends upward from the connection between the hose 5 and the nozzle 4. The surrounding portion also extends a portion of the vertical length of the entire nozzle 4. The fastener 42 is mounted on the surrounding portion. The surrounding portion has an open clearance opening 41 on the other side of the fastener 42. The width of the clearance opening 41 is greater than the diameter of the hose 5, and the depth of the clearance opening 41 is greater than the radius of the hose 5. The clearance opening 41 is used to make way for the hose 5, so that when the nozzle 4 is fastened to the side frame 35, the hose 5 has space to make way downward from the nozzle 4, avoiding the hose 5 from squeezing each other in the space between the nozzle 4 and the end of the bend 3 after bending, which would make it inconvenient to fasten the nozzle 4.

[0029] In summary, during implementation, turning on switch 2 allows water to flow through valve seat 1. Water flows through hose 5 and sprays from nozzle 4. The user holds nozzle 4 and pulls it downwards to pull nozzle 4 and hose 5 out of bend 3. To stabilize the pulled-out length, rotate operating ring 33, moving the buckle 34 at the bottom of operating ring 33 below the inner cavity of eccentric base 32, thus intersecting with hose 5. Pulling hose 5 so that buckle 34 is positioned between the two corrugated rings 51, then releasing the tension on nozzle 4 or hose 5, the retracted hose 5 is locked by buckle 34 through corrugated rings 51, thus limiting its retraction and fixing the pulled-out length. The user then needs to... When the nozzle 4 sprays water at a certain angle, if you need to wash your face in the kitchen or rinse your mouth after a meal, after the extended length is fixed, align the slot 43 on the nozzle 4's buckle 42 with the side bracket 35 and insert it so that the nozzle 4 points in the desired direction, such as towards the user's face. At this time, the user can perform convenient face washing and mouth rinsing operations. At the same time, the operating ring 33 retains the freedom of rotation on the eccentric base 32. The fixed nozzle 4 can rotate with the operating ring 33. When the rotation causes the hose 5 to disengage from the buckle 34 and retract, the nozzle 4 remains stable due to the restriction of the side bracket 35 and will not affect the nozzle 4. Thus, the nozzle 4 can be used at the required angle.

[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
