This application claims priority to Chinese Utility Model Patent Application No. 202220722244.0, filed Mar. 30, 2022, the entirety of which is incorporated herein by reference.
The present disclosure relates generally to the technical field of draw-out type faucets, and, specifically, to an operating mechanism and a hose drawing device.
Draw-out type faucets are often used in the sanitary industry, for example, draw-out kitchen faucets or basin faucets having a retractable hose and optional spray head. Generally, an operating mechanism is usually assembled on one side of the hose body or the housing to prevent the drawn water hose from falling back naturally. For example, an existing operating mechanism configuration can comprise a slider, a telescopic pin, a sliding pin, a ramp, and a guide member. The slider can be pushed upward by a guide sleeve on the water hose, which causes the telescopic pin to move along the ramp and extend. The sliding pin is positioned in the guide member to limit the slider to fall back and prevent the water hose from falling back by stopping the guide sleeve from falling back through the telescopic pin. When the user pulls the water hose again, the slider moves up again and the sliding pin falls along the guide member, so that the slider can fall back to the original position, and the telescopic pin moves down along the ramp and contracts, so that the water hose and the guide sleeve can fall back to the original position.
The existing operating mechanism requires a large space in the vertical direction and a complicated assembly relationship.
In view of this, it becomes necessary to provide an operating mechanism and a hose drawing device with simple structure, convenient assembly and small space occupation.
The object of the application is to overcome the shortcomings of other hose drawing mechanisms and provide an operation mechanism and a hose drawing device with simple structure, convenient assembly, and small space occupation.

For the operation mechanism and hose drawing device of the application, when the button switch is in the initial state, the top pin is separated from the hose body. When the water hose is pulled upward, the hose guide sleeve may press the button switch. The button switch moves toward the swing arm, which makes the swing arm rotate and then drives the top pin to extend toward the hose body. The button switch remains in the corresponding position, the top pin remains extended, and the falling hose guide sleeve is blocked by the top pin so as to prevent the water hose from falling back automatically. When the water hose is pulled upward again, the hose guide sleeve presses the button switch again. The button switch is reset to the initial state, and the top pin retracts and separates from the hose body under the action of the elastic member. The hose guide sleeve may fall in the hose body, and the water hose is reset.

It should be noted that, terms as used in the following description, “front”, “rear”, “left”, “right”, “up” and “down” indicate a direction in the figures, and terms “inner” and “outer” respectively indicate the direction toward or away from a geometric center of a particular part.
As shown in
The hose guide sleeve 2 is assembled in the hose body 1 with clearance, the mounting box 5 is mounted on the outside of the hose body 1, and the swing arm 6 is pivotally mounted in the mounting box 5. In examples, the mounting box 5 may be a box-type structure, which is coupled to one side of the hose body 1. The mounting box 5 has an upper guide sleeve 53 and a lower guide sleeve 54. The upper guide sleeve 53 and the lower guide sleeve 54 extend along the horizontal direction and are communicated with a channel 11 of the hose body 1, respectively.
The button switch 7 is slidably assembled in the upper guide sleeve 53. One end of the button switch 7 (i.e., a slide bar 72) is in contact with the upper end of the swing arm 6, and the opposing end of the button switch 7 (i.e., a button 71) is incorporated within the hose body 1, which will be described in greater detail below. The button switch 7 can be actuated and reset by the upwardly moving hose guide sleeve 2. The top pin 8 is slidably assembled in the lower guide sleeve 54. The top pin 8 is in contact with the lower end of the swing arm 6. The lower guide sleeve 54 is mounted with the elastic member 9 for driving the top pin 8 toward the swing arm 6.
In examples, the button switch 7 has an initial state and an actuated state. When the button switch 7 is in the initial state, the top pin 8 is separated from the hose body 1. When the button switch 7 is in the actuated state, the end of the top pin 8 is inserted into the hose body 1 and may prevent the hose guide sleeve 2 from falling down.
An operating mechanism 100 of the present application may be used for an example faucet drawing out, pause operation of the water hose 200, further illustrated in
The hose body 1 may be provided with the channel 11 such that the water hose 200 may pass through. The hose guide sleeve 2 is assembled in the channel 11 of the hose body 1 and can slide up and down in the channel 11. The lower end of the hose guide sleeve 2 may be coupled to a sleeve barrel 4, which is sleeved on the water hose 200. A snap ring 3 can be mounted at the connection between the sleeve barrel 4 and the hose guide sleeve 2, and the snap ring 3 may be used to clamp the water hose 200.
The swing arm 6 can be mounted in the mounting box 5 through a pivot shaft 61, wherein the pivot shaft 61 extends horizontally and the swing arm 6 may swing around the pivot shaft 61. The swing arm 6 can be assembled between the button switch 7 and the top pin 8. When the button switch 7 acts on the swing arm 6 to make it swing, the distance between the upper end of the swing arm 6 and the hose body 1 gradually increases and the distance between the lower end of the swing arm 6 and the hose body 1 gradually decreases, thereby driving the top pin 8 to extend toward the channel 11 of the hose body 1. As the top pin 8 acts on the swing arm 6 to make it swing, the distance between the lower end of the swing arm 6 and the hose body 1 gradually increases, and the distance between the upper end of the swing arm 6 and the hose body 1 gradually decreases, thereby driving the button switch 7 to reset.
The button switch 7 is fitted in the upper guide sleeve 53 in the way of clearance fit, and the button switch 7 may slide in the upper guide sleeve 53. One end of the button switch 7 is kept in contact with the upper end of the swing arm 6, and the other end of the button switch 7 is in the channel 11 of the hose body 1 so as to be able to be actuated by the upwardly moving hose guide sleeve 2.
The top pin 8 is assembled in the lower guide sleeve 54 with clearance and one end of the top pin 8 is kept in contact with the lower end of the swing arm 6. As the top pin 8 is driven by the swing arm 6 to slide toward the tube body 1, the opposing end of the top pin 8 may extend into the channel 11 to prevent the hose guide sleeve 2 from falling. In examples, the elastic member 9 can be assembled in the lower guide sleeve 54, which is used to drive the top pin 8 to move toward the swing arm 6, so that the other end of the top pin 8 leaves the channel 11.
In examples, as illustrated above, the button switch 7 has an initial state and an actuated state. In the initial state, the length of the button switch 7 extending into the channel 11 is longer than the length of the button switch 7 in the actuated state. The button switch 7 may be driven to slide toward the swing arm 6 by moving the hose guide sleeve 2 upward, wherein the hose guide sleeve 2 is moved in a first, upwardly motion (e.g., acting as a trigger or button-like feature) pressing the button switch, which activates the actuated state. In the actuated state, the length of the button switch 7 extending into the channel 11 is less than the length of the button switch 7 is extended into the channel 11 in the initial state, because the button switch 7 has been sliding toward the swing arm 6. In the actuated state, the button switch 7 slides toward the swing arm 6, which drives the swing arm 6 to rotate. After the swing arm 6 rotates to drive the top pin 8 to extend out into the channel 11, the button switch 7 remains in the actuated position so that the top pin 8 remains extended.
In the actuated state, the end of the button switch 7 still, at least partially, remains in the channel 11, such that the button switch 7 may be driven to slide toward the swing arm 6 by moving the hose guide sleeve 2 up again, wherein the hose guide sleeve 2 is moved in a second, upwardly motion (e.g., acting as a second trigger or button-like feature) to press the button switch an additional, second time. The button switch 7 no longer remains in the actuated position and the button switch 7 may be reset to the initial state. Thus, recalling, at least in part, the top pin 8 from the channel 11.
The lower end of the hose guide sleeve 2 will not exceed past the distance of the push button switch 7 each time the hose guide sleeve 2 is moved upward, which may prevent the end of the button switch 7 from extending into the channel 11 and from affecting the falling down of the hose guide sleeve 2.
In the initial state, the hose guide sleeve 2 is at a distance under the top pin 8. When he button switch 7 is in the initial state, the top pin 8 and the hose body 1 are in a separated state and the end of the top pin 8, facing the hose body 1, is received in the lower guide sleeve 54, which will not affect the upward movement of the hose guide sleeve 2.
In this example, the button switch 7 can be a button, for example, a button of a ballpoint pen, that can be pressed once to operate and pressed twice to reset. In examples, on the first press, the button switch 7 can be pressed down and, in the second press, the button switch 7 is reset.
With additional reference to
When the user needs the water hose 200 to be reset, the water hose 200 can be pulled up again, which in turn moves upwardly the hose guide sleeve 2 and presses the button switch 7 again. Upon an additional activation, the button switch 7 no longer stays in the actuated position or leaves the actuated position, and no longer applies force to the swing arm 6. Under the action of the elastic member 9, the top pin 8 moves toward the swing arm 6, and the end of the top pin 8 leaves the channel 11. The top pin 8 drives the swing arm 6 to rotate, which in turn drives the button switch 7 to move toward the channel 11 and resets to the initial state. After the user releases the water hose 200, the falling hose guide sleeve 2, within the hose body 1 during the actuation state, is no longer blocked by the top pin 8, and the water hose 200 can fall and reset.
Therefore, the present disclosure provides an operating mechanism, in which a swing arm 6 is used for linkage between the button switch 7 and the top pin 8, which takes up a small space occupation, simple structure, and is easy to assemble.
In one of the examples, as shown in
A limiting guide cylinder 55 having guide grooves 551 may be fixedly mounted in the upper guide sleeve 53 of the box body 51. The limiting guide cylinder 55 may have a limiting end face 552 on its end face toward the swing arm 6. In examples, the button 71 can have a ring gear 711 coupled to it. There may be one or more bumps 712 coupled about the circumference of the surface of the ring gear 711. There may be one or more toggle teeth 722 coupled to the slide bar 72 for toggling the ring gear 711 to rotate.
The button 71 may be in a clearance fit with the limiting guide cylinder 55, such that one end of the button 71 is in the hose body 1 and the one or more toggle teeth 722 engage with the ring gear 711 and may toggle the ring gear 711 to rotate. In examples, when the button switch 7 is in the initial state, the one or more bumps 712 may be fitted in the guide grooves 551 in the way of clearance fit. When the button switch 7 is in the actuated state, the one or more bumps 712 may leave the guide grooves 551, such that the one or more bumps 712 are blocked by the limiting end face 552.
In examples, the button switch 7 may comprise a button 71 and a slide bar 72, with one end of the slide bar 72 in contact with the upper end of the swing arm 6 and the opposing end of the slide bar 72 being slidingly coupled to the button 71. The button 71 may have a central hole 714 with an opening toward the swing arm 6. the opposing end of the button 71 may extend into the channel 11 having a hemispherical end 713. One end of the slide bar 72 may be fitted to be received in the central hole 714 in the way of clearance fit, and the axial clearance between the hemispherical end 713 and the central whole 714 can be adjusted according to the working conditions to meet the need of rotating the button 71.
One end of the button 71, facing the swing arm 6, may have a ring gear 711 with one or more ring gear teeth 7111 facing the swing arm 6. The one or more ring gear teeth 7111 may have a circular angle of a. The one or more bumps 712 on the circumference surface of the ring gear 711.
In examples, a limiting guide cylinder 55 may be fixedly mounted in the upper guide sleeve 53 and guide grooves 551 may extend along the axial direction are provided on the wall of the limiting guide cylinder 55. The one or more bumps 712 may be fitted in the guide grooves 551 in the way of clearance fit. The end face of the limiting guide cylinder 55 facing toward the swing arm 6 may be a limiting end face 552, which is used to block the bump 712 from leaving the guide grooves 551 to temporarily limit the button 71 so that the button switch 7 remains in the actuated position.
When the button switch 7 is in its initial state, the one or more bumps 712 may be fitted in the guide grooves 551 in the way of clearance fit and the button 71 can only slide axially and not rotate.
In examples, when the hose guide sleeve 2 moves up to drive the button 71, the sliding distance of the button 71 along the axial direction can be greater than the distance between the one or more bumps 712 in the guide grooves 551 and the limiting end face 552. In examples. the one or more bumps 712 can be disengaged from the guide grooves 551 and the button 71 can be rotated relative to the limiting guide cylinder 55.
In examples, when the button switch 7 is first actuated or pressed by the hose guide sleeve 2, the button switch 7 may be actuated, and the hose guide sleeve 2 moves up to drive the button 71 to act. Then, the slide bar 72 slides outwardly relative to the channel 11 and drives the swing arm 6 to swing, so that the top pin 8 extends into the channel 11. The one or more bumps 712 are removed from the guide grooves 551, while the ramp 7221 of the toggle teeth 722 act on the ring gear teeth 7111 to make the button 71 rotate. After the button 71 is turned a degree(s), the one or more bumps 712 may be no longer aligned with the guide grooves 551 but correspond to the limiting end face 552. After the button 71 is turned a degree(s), the toggle teeth 722 engage with the next ring gear teeth 7111, and the button 71 moves backward toward the channel 11. Thus, the one or more bumps 712, blocked by the limiting end face 552, keep the button switch 7 in the actuated position and keep the swing arm 6 against the top pin 8 so that its end remains in the channel 11 to prevent the hose guide sleeve 2 from falling.
In examples, when the button switch 7 is acted or pressed by the hose guide sleeve 2 for the second time, the button 71 may slide toward the swing arm 6 once again. The ramp 7221 of the toggle teeth 722 act on the ring gear teeth 7111 to make the button 71 rotate a degree(s) (again). The one or more bumps 712 leave the limit end 552 and align with the guide grooves 551. Then, the one or more bumps 712 may enter into the guide grooves 551. The button 71 may no longer hold the slide bar 72. In example. the top pin 8 may retract and rotate against the swing arm 6, under the action of the elastic member 9, and the button 71 slides toward the channel 11 to reset to the initial state.
In one of the examples, as shown in
In examples, when the button switch 7 is in the actuated state, the one or more bumps 712 may be blocked by the first limiting face 5521, which may be a concave surface recessed toward the channel 11 and facilitate keeping the hemispherical end 713 of the button 71, at least partially, in the channel 11 so that it can be pressed or actuated by the hose guide sleeve 2 that moves up, again.
When the upwardly moving hose guide sleeve 2 presses or actuates the button 71 for the second time, the button 71 may be rotated under the action of the toggle teeth 722. The one or more bumps 712 cross over the second limiting face 5522 and enter into the next guide groove 551 and, thus, can be reset.

An operating mechanism 100 of the present application may be used for an example faucet drawing out, pause operation of the water hose 200, further illustrated in
In examples, the water hose 200 is provided with a weight 300. The hose guide sleeve 2, the snap ring 3 and the sleeve barrel 4 may be sleeved on the water hose 200, which passes through the channel 11 of the hose body 1. A faucet may be attached to the upper end of the water hose 200. In the initial state, the hose guide sleeve 2 is under the top pin 8.
In examples, when the user needs to pull up the water hose 200, the hose guide sleeve 2 moves up and over the top pin 8, the hose guide sleeve 2 is in contact with the button switch 7 and presses the button switch 7. The button switch 7 slides toward the swing arm 6, which in turn drives the swing arm 6 to rotate and drives the end of the top pin 8 into the channel 11. The button switch 7 remains in the actuated position and the top pin 8 remains extended. After the user releases the water hose 200, the water hose 200 drives the hose guide sleeve 2 to fall under the action of the weight 300, and the falling hose guide sleeve 2 is blocked by the top pin 8. Thus, forcing the water hose 200 to stop or cease from falling back into or through the channel 11, allowing the user to continue to use the faucet in the extended or actuated position.
In examples, when the user needs the water hose 200 to be reset, the water hose 200 is pulled up once again, forcing the hose guide sleeve 2 to lift upwardly and press the button switch 7 again. Thus, the button switch 7 no longer stays in the actuated position or leaves the actuated position and no longer applies a force to the swing arm 6. Under the action of the elastic member 9, the top pin 8 moves toward the swing arm 6 and the end of the top pin 8 leaves the channel 11. The top pin 8 drives the swing arm 6 to rotate, which drives the button switch 7 to move toward the channel 11 and resets to the initial state. After the user releases the water hose 200, the falling hose guide sleeve 2 is no longer blocked by the top pin 8 and the water hose 200 falls, which returns the hose guide sleeve 2 to its original position.
