Description

Technical Field

[0001] This invention relates to the field of bathroom equipment technology, and in particular to a hovering mechanism and a water outlet device. Background Technology

[0002] In related technologies, pull-out faucets typically achieve their pull-out function through a control box. For ease of use, the control box includes components such as ball bearings and auxiliary wheels. The suspension and reset of the spray head are achieved through the cooperation of these components, allowing the nozzle to lock and remain suspended after being pulled out a certain distance, eliminating the need for the user to continuously pull the nozzle. However, the locking and reset functions require the cooperation of auxiliary wheels, ball bearings, and auxiliary wheels. The large number of components affects the stability of the coordination, and the complex movement trajectory of the ball bearings makes implementing the suspension and reset functions difficult. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a hovering mechanism that simplifies the structure of the hovering mechanism, reduces the number of parts, simplifies the action coordination between the parts, and facilitates the realization of hovering and resetting functions.

[0004] The present invention also proposes a water outlet device having the above-mentioned hovering mechanism.

The limiting structure is provided with a locking boss and a reset boss, which are spaced apart along a first direction. The reset assembly includes a counterweight, a supporting member, and a first elastic member. The counterweight is provided with a fixing portion for fixing to a pull-out tube, and the counterweight is movable relative to the limiting structure along the first direction. The supporting member is slidably connected to the counterweight and is movable relative to the counterweight along a second direction. The supporting member abuts against the locking boss on the side facing the reset boss in the first direction, and also abuts against the surface of the reset boss in the second direction. The first elastic member is connected to the supporting member and applies a force to the supporting member along the second direction near the fixing portion, the second direction intersecting the first direction.

[0006] The hovering mechanism according to embodiments of the present invention has at least the following beneficial effects: By sliding the abutment on the counterweight, the abutment can move in a second direction, allowing it to move from the lower side of the locking boss in the first direction to the upper side. The locking boss's support of the abutment restricts the counterweight's descent under its own weight, thereby achieving hovering of the water outlet head. When the counterweight continues to move upward in the first direction, the movement of the abutment in the second direction allows it to move to abut against the surface of the reset boss in the second direction.

[0047] The hovering mechanism and water outlet device of this application according to the accompanying drawings are described below.

[0048] Reference Figures 1 to 5 and Figure 12 According to an embodiment of the present invention, the hovering mechanism 100 includes a limiting structure 200 and a reset assembly 300. The limiting structure 200 is provided with a locking boss 220 and a reset boss 230, which are spaced apart along a first direction. The reset assembly 300 includes a counterweight 310, a supporting member 320, and a first elastic member 330. The counterweight 310 is provided with a fixing part 311, which is used to fix it to the pull tube 420 so that the counterweight 310 can move relative to the limiting structure 200 in the first direction as the pull tube 420 is pulled. The supporting member 320 is slidably connected to the counterweight 310 and can move relative to the counterweight 310 in a second direction. The supporting member 320 can abut against the side of the locking boss 220 facing the reset boss 230 in the first direction and can abut against the surface of the reset boss 230 in the second direction. The first elastic member 330 is connected to the abutment member 320. The first elastic member 330 is used to apply a force to the abutment member 320 along the second direction close to the fixing part 311. The second direction intersects with the first direction.

[0049] By sliding the abutment 320 on the counterweight 310, the abutment 320 can move in the second direction, allowing it to move from the lower side of the locking boss 220 in the first direction to the upper side. The locking boss 220's support of the abutment 320 restricts the counterweight 310 from falling under its own weight, thus suspending the water outlet head 430 of the water outlet device 10. When the counterweight 310 continues to move upward in the first direction, the movement of the abutment 320 in the second direction allows it to move to abut against the surface of the reset boss 230 in the second direction. The reset boss 230's support allows the abutment 320 to move from the upper side of the locking boss 220 to the lower side under its own weight, thus resetting the water outlet head 430. Compared with the hovering mechanism in the prior art, the hovering mechanism 100 of this application embodiment has fewer parts and the action coordination between the parts is simple, making it easy to implement the hovering function and the reset function.

[0050] Specifically, the counterweight 310 can move to a first position, a second position, and a third position in a first direction as the pull tube 420 is pulled. In the first position, the counterweight 310 is spaced apart from the locking boss 220 in the first direction. In the second position, the abutment 320 is located between the locking boss 220 and the reset boss 230, and the abutment 320 abuts against the reset boss 230 in the first direction. In the third position, the abutment 320 abuts against the surface of the reset boss 230 in a second direction. The counterweight 310 can move from the third position to the first position.

[0051] The operator pulls the pull tube 420 to move the counterweight 310 from the first position to the second position along the first direction, where it is suspended by the cooperation of the abutment 320 and the locking boss 220. When resetting is required, the operator continues to pull the pull tube 420 to move the counterweight 310 to the third position along the first direction, where the abutment 320 abuts against the reset boss 230. The reset boss 230 resolves the interference between the abutment 320 and the locking boss 220, allowing the counterweight 310 to move from the third position back to the first position, thus resetting the counterweight. It is understood that when the counterweight 310 is in the second position, the suspension mechanism 100 is in a locked state. When the counterweight 310 is in the third position and tends to move towards the first position, the suspension mechanism 100 is in a reset state.

[0052] Reference Figure 2 , Figure 3 and Figure 8 The limiting structure 200 includes a first body 210, the relative position of the first body 210 and the counterweight 310 in the second direction remains unchanged, and the locking boss 220 and the reset boss 230 are connected to the side of the first body 210 away from the fixing part 311 in the second direction. The first body 210 can be fixed to a separate fixing frame (not shown in the figure), or, in some embodiments, the first body 210 can be fixed to the base 410 of the faucet 400 (not shown in the figure), so that the first body 210 is located on one side of the pull tube 420 in the second direction, so that the first body 210 can correspond to the counterweight 310 in the first direction, ensuring that the abutment 320 can move to abut against the locking boss 220 and the reset boss 230.

[0053] The first elastic element 330 can be a conventional elastic element in the art, such as a spring, elastic plastic, or bellows. One end of the first elastic element 330 abuts against the counterweight 310, and the other end abuts against the supporting member 320. The two ends of the first elastic element 330 are distributed along the second direction to apply a force along the second direction to the supporting member 320 towards the fixing part 311. The side of the counterweight 310 where the fixing part 311 is provided also has a clearance hole or clearance groove to prevent the counterweight 310 from interfering with the locking boss 220 and the reset boss 230. The fixing part 311 can be a fastener provided on the counterweight 310.

[0054] On the other hand, since the counterweight 310 is fixed on the pull tube 420, and the limiting structure 200 and the counterweight 310 are corresponding in the first direction, the limiting structure 200 and the reset assembly 300 are both arranged along the pull tube 420, which effectively utilizes the space occupied by the pull tube 420 in the length direction, making the structure of the suspension mechanism 100 compact and occupying little space, reducing interference, so that the pull tube 420 can have a longer pull length.

[0055] Specifically, the second direction is any direction on the plane intersecting the first direction. In some embodiments, the second direction is any direction on the plane perpendicular to the first direction, to facilitate control of the movement direction of the abutment 320 and its engagement with the locking boss 220 and the reset boss 230. Further, in embodiments where the pull-out tube 420 is a cylindrical tube, the first direction is the axial direction of the pull-out tube 420, and the second direction is the radial direction of the pull-out tube 420.

[0056] Reference Figure 2 , Figure 3 and Figure 8 In a further embodiment, the first body 210 is provided with a first hole 211 extending along a first direction. The first hole 211 is used to pass through the pull-out tube 420. The locking boss 220 and the reset boss 230 are connected to the outer surface of the first body 210 in a second direction. By limiting the pull-out tube 420 through the first hole 211, it can be ensured that the counterweight 310 moves along the first direction when it moves close to the limiting structure 200 as the pull-out tube 420 moves. Furthermore, the relative positions of the locking boss 220 and the reset boss 230 with the pull-out tube 420 remain stable, improving the stability of the fit between the limiting structure 200 and the reset assembly 300.

[0057] Reference Figure 2 , Figure 3 and Figure 8In some embodiments, the locking boss 220 and the reset boss 230 are integrally formed on the first body 210 by injection molding, welding, or other methods. The locking boss 220 and the reset boss 230 are spaced apart and fixed to each other in the first direction. The locking boss 220 and the reset boss 230 can be annular bosses surrounding the outer surface of the first body 210 to improve the fault tolerance rate of the fit with the reset assembly 300. Alternatively, in some embodiments, multiple locking bosses 220 and reset bosses 230 are provided, with each locking boss 220 and each reset boss 230 surrounding the outer surface of the first body 210, and each locking boss 220 and each reset boss 230 corresponding one-to-one in the first direction, which can also improve the fault tolerance rate of the fit with the reset assembly 300. Multiple abutment members 320 can be provided and arranged around the fixing part 311. Multiple abutment members 320 can reduce the average force on a single abutment member 320, improve locking stability, reduce the possibility of damage or deformation of a single abutment member 320, and extend the service life of the suspension mechanism 100.

[0058] The locking boss 220 has a first side surface 222, located on the side of the locking boss 220 away from the first body 210. The first side surface 222 is used to abut against the abutment 320, and the distance between the first side surface 222 and the outer surface of the first body 210 is 'a'. The reset boss 230 has a second side surface 237, located on the side of the reset boss 230 away from the first body 210. The second side surface 237 is used to abut against the abutment 320, and the distance between the second side surface 237 and the outer surface of the first body 210 is 'b', satisfying a < b. Since the distance b is greater than the distance a, when the abutment 320 abuts against the reset boss 230, the distance between it and the outer surface of the first body 210 is greater. When the abutment 320 disengages from the reset boss 230, it needs to move a certain distance under the action of the first elastic member 330 before it reaches the minimum distance 'a' between the abutment 320 and the outer surface of the first body 210. Therefore, by adjusting the distance between the reset boss 230 and the locking boss 220 in the first direction, the minimum distance between the abutment 320 and the outer surface of the first body 210 is equal to or greater than 'a' when the abutment 320 moves to the side of the locking boss 220 in the first direction after disengaging from the reset boss 230. This allows the abutment 320 to move from the upper side of the locking boss 220 to the lower side of the locking boss 220, thereby achieving the reset function.

[0059] In other embodiments, reference is made to Figures 1 to 8The reset boss 230 includes a reset portion 231 and a connecting portion 232 connected to each other. The connecting portion 232 is slidably connected to the first body 210. The reset portion 231 protrudes from the connecting portion 232 on the side opposite to the first body 210. The reset boss 230 can move relative to the locking boss 220 in a first direction. The limiting structure 200 also includes a second elastic member 240 connected to the reset boss 230. The second elastic member 240 is used to apply a force to the reset boss 230 away from the locking boss 220. Under the action of the second elastic member 240, the reset portion 231 and the locking boss 220 are maintained at a distance in the first direction, so that the abutment 320 can move between the reset portion 231 and the locking boss 220 to perform a locking operation. When the counterweight 310 moves to the third position, the holding member 320 abuts against the reset part 231. At this time, the pull of the pull tube 420 is released, and the counterweight 310 will fall along the first direction under its own weight. Since the holding member 320 abuts against the reset part 231 under the action of the first elastic member 330, there is a certain friction between the holding member 320 and the reset part 231. Under the action of the friction, the reset part 231 can overcome the elastic force of the second elastic member 240 and gradually approach the locking boss 220, reducing the distance between the reset part 231 and the locking boss 220 in the first direction.

[0060] It is understandable that when the abutment 320 disengages from the abutment of the reset boss 230, the smaller the distance between the reset boss 230 and the locking boss 220 in the first direction, the easier it is for the abutment 320 to move to be parallel with the locking boss 220 in the first direction so that it can subsequently pass over the locking boss 220 along the lower side of the first direction. For example, when the abutment 320 disengages from the abutment of the reset boss 230, and the reset boss 230 and the locking boss 220 abut in the first direction, then a = b is satisfied, which allows the abutment 320 to pass over the locking boss 220 along the lower side of the first direction. Furthermore, if a < b, the movement of the abutment 320 over the locking boss 220 along the lower side of the first direction becomes more stable, preventing the abutment 320 from being unable to overtake the locking boss 220 along the lower side of the first direction due to wear and tear after long-term use. Alternatively, in some embodiments, when the abutment 320 disengages from the abutment of the reset boss 230, the reset boss 230 and the locking boss 220 abut in the first direction or have only a small gap, a ≥ b. In this case, by providing a small guide slope (not shown in the figure) on the locking boss 220, the abutment 320 can be guided to abut against the surface of the locking boss 220 in the second direction, so that the abutment 320 can overtake the locking boss 220 along the lower side of the first direction. The guide ramp connects the surface of the locking boss 220 in the second direction and the upper surface in the first direction. The distance between the guide ramp and the first hole 211 gradually decreases along the direction close to the reset boss 230. It is understandable that if the guide ramp connects the surface of the locking boss 220 in the second direction and the outer surface of the first body 210 in the second direction, it would affect the holding of the locking boss 220 against the abutment 320, thus affecting the locking effect. However, by connecting the surface of the locking boss 220 in the second direction and the upper surface in the first direction, the guide ramp provides a surface for the locking boss 220 to directly abut against the abutment 320 in the second direction, ensuring the locking effect.

[0061] Specifically, the sliding connection between the connecting part 232 and the first body 210 can be achieved by providing a groove 212 on one of the outer surface of the first body 210 and the connecting part 232, and a sliding table (not shown in the figure) on the other. The sliding connection is achieved through the cooperation of the sliding table and the groove 212. The sliding table is confined within the groove 212 to prevent the connecting part 232 from disengaging from the first body 210. The specific confining method can refer to the conventional groove and sliding table cooperation in the art, which will not be described in detail here. The second elastic element 240 can be selected as a spring, elastic plastic, bellows, or other conventional elastic elements in the art. One end of the second elastic element 240 abuts against the locking boss 220, and the other end of the spring abuts against the reset boss 230 to apply a force to the reset boss 230 away from the locking boss 220.

[0062] Reference Figure 7 and Figure 8 In a further embodiment, the outer surface of the first body 210 is provided with a groove 212, which extends along a first direction. A reset boss 230 is sleeved on the outer surface of the first body 210, and at least a portion of the connecting portion 232 is located within the groove 212, allowing the connecting portion 232 to move within the groove 212. By configuring the reset boss 230 to be sleeved on the outer surface of the first body 210, the connecting portion 232, once located within the groove 212, will not detach from the groove 212 due to the shape limitation of the reset boss 230. Since the first body 210 needs to provide connection and sliding space for the reset boss 230, its volume is relatively large, making deformation more difficult compared to the reset boss 230. The slide groove 212 is set on the first body 210, and a part of the connecting part 232 is used as a slide protruding into the slide groove 212. When the connecting part 232 is to be assembled into the slide groove 212, it is only necessary to reset the boss 230 to overcome the deformation so that a part of the connecting part 232 can slide into the slide groove 212.

[0063] Reference Figure 7 and Figure 8 Furthermore, the reset boss 230 also includes an extension 233, which connects the reset part 231 and the connecting part 232. The reset part 231 extends in a direction away from the locking boss 220. The extension 233 is provided with an annular hole 234, which surrounds the connecting part 232 and penetrates the extension 233 in a second direction. The extension 233 ensures that the deformation of the reset boss 230 during assembly with the first body 210 only occurs in the extension 233, and the annular hole 234 reduces the difficulty of deformation, thereby reducing the difficulty of the connecting part 232 entering the slide groove 212, and thus reducing the assembly difficulty of the reset boss 230 and the first body 210.

[0064] Reference Figures 6 to 8In some embodiments, the reset boss 230 is provided with a fourth surface 235, which is located on the side of the reset boss 230 away from the locking boss 220. The distance between the fourth surface 235 and the first body 210 gradually decreases along the direction away from the locking boss 220. The fourth surface 235 is used to abut against the abutment 320. After the abutment 320 moves to the upper side of the reset boss 230 in the first direction, when the abutment 320 moves to the lower side in the first direction for reset, it can be guided by the fourth surface 235 to abut against the surface of the reset boss 230 in the second direction, instead of abutting against the surface of the reset boss 230 away from the locking boss 220 in the first direction, so that the abutment 320 is jammed. On the other hand, in the embodiment where the reset boss 230 is slidably connected to the first body 210, when the abutment 320 abuts against the fourth surface 235, the fourth surface 235 can convert the abutment force of the abutment 320 into component forces along the first direction and the second direction. The component force along the second direction can make the reset boss 230 move toward the locking boss 220. Compared with the method of using friction, the fourth surface 235 can better use the weight of the counterweight 310 to drive the reset boss 230 to move, making the movement of the reset boss 230 more stable, and can overcome the greater elastic force of the second elastic member 240, making it easier for the reset boss 230 to move to abut against the locking boss 220, so that the abutment 320 can pass over the locking boss 220 along the lower side of the first direction to reset.

[0065] Or, refer to Figure 6 , Figure 9 and Figure 10 In some embodiments, the abutment 320 is provided with a fifth surface 322, which is located on the side of the abutment 320 facing the locking boss 220 from the reset boss 230. The distance between the fifth surface 322 and the fixing part 311 in the second direction gradually decreases along the direction from the locking boss 220 to the reset boss 230. The fifth surface 322 is used to abut against the reset boss 230. After the abutment 320 moves to the upper side of the reset boss 230 in the first direction, when the abutment 320 moves to the lower side in the first direction to reset, it can be guided by the fifth surface 322 to abut against the surface of the reset boss 230 in the second direction, instead of abutting against the surface of the reset boss 230 away from the locking boss 220 in the first direction, so that the abutment 320 is locked.

[0066] Reference Figure 6 , Figure 9 and Figure 10In some embodiments, in addition to the fourth surface 235 on the reset boss 230, the abutment 320 is provided with a fifth surface 322. The fourth surface 235 and the fifth surface 322 are provided together to jointly play a guiding role and reduce the rigid impact between the abutment 320 and the reset boss 230. By adjusting the slope of the fourth surface 235 and the fifth surface 322, the guiding effect and the magnitude of the component forces along the first and second directions can be adjusted.

[0067] Specifically, the fourth surface 235 can be an inclined plane or a curved surface, and the fifth surface 322 can be an inclined plane or a curved surface.

[0068] Reference Figure 3 , Figure 9 and Figure 10 In some embodiments, the abutment 320 has a first surface 323 on one side of the locking boss 220 facing the reset boss 230. The distance between the first surface 323 and the fixing part 311 in the second direction gradually increases along the direction of the locking boss 220 towards the reset boss 230. The first surface 323 is used to abut against the locking boss 220 and the reset boss 230. The first surface 323 can guide the movement of the abutment 320, so that when the first surface 323 abuts against the locking boss 220, the abutment 320 can move in the second direction away from the fixing part 311, so that the abutment 320 can move between the locking boss 220 and the reset boss 230 and abut against the surface of the locking boss 220 facing the reset member in the first direction, entering a locking state. Furthermore, when the first surface 323 abuts against the guide boss, the abutting member 320 can move in the second direction away from the fixing part 311, so that the abutting member 320 can move to abut against the surface of the reset boss 230 in the second direction, so as to enter the subsequent reset state.

[0069] Reference Figure 3 and Figure 8In some embodiments, the locking boss 220 has a second surface 221 on the side opposite to the reset boss 230, and the second surface 221 gradually approaches the first body 210 along the direction opposite to the reset boss 230. The second surface 221 is used to abut against the abutment 320. The reset boss 230 has a third surface 236 on the side facing the locking boss 220, and the third surface 236 gradually approaches the first body 210 along the direction facing the locking boss 220. The third surface 236 is used to abut against the abutment 320. The second surface 221 can guide the movement of the abutment 320, so that when the second surface 221 abuts against the abutment 320, the abutment 320 can move in the second direction in the direction opposite to the fixing part 311, so that the abutment 320 can move between the locking boss 220 and the reset boss 230 and abut against the surface of the locking boss 220 facing the reset boss 230 in the first direction, entering a locking state. The third surface 236 can guide the movement of the abutment 320, so that when the third surface 236 abuts against the abutment 320, the abutment 320 can move in the second direction away from the fixing part 311, so that the abutment 320 can move to abut against the surface of the reset boss 230 in the second direction, so as to enter the subsequent reset state.

[0070] Reference Figure 3 , Figures 8 to 10 In some embodiments, in addition to the first surface 323 on the abutment 320, the locking boss 220 is provided with a second surface 221, and the reset boss 230 is provided with a third surface 236. The combined arrangement of the first surface 323, the second surface 221, and the third surface 236 can play a guiding role and reduce the rigid impact between the abutment 320 and the locking boss 220, and between the abutment 320 and the reset boss 230.

[0071] Specifically, the first surface 323 can be an inclined surface or a curved surface, the second surface 221 can be an inclined surface or a curved surface, and the third surface 236 can be an inclined surface or a curved surface.

[0072] Reference Figure 2 , Figure 7 and Figure 8In some embodiments, the hovering mechanism 100 further includes a connector 250, one end of which is connected to the first body 210, and the other end of which is provided with a thread 251 for fixed connection with the faucet 400. By providing the thread 251 on the connector 250, the assembly of the first body 210 can match the connecting threads 251 on most of the base 410 of the faucet 400, thereby improving the applicability of the hovering mechanism 100 and enabling it to be applied to pull-out faucets such as basin pull-out faucets or kitchen pull-out faucets. The connector 250 and the first body 210 can be detachably connected by snap-fit ​​or by pre-tightening components such as bolts.

[0073] Reference Figures 3 to 6 , Figure 9 and Figure 10 In some embodiments, the counterweight 310 has a sliding groove (not shown in the figure) on the side of the limiting boss 315 facing the reset boss 230. The sliding groove extends along the second direction, and the abutment 320 is disposed in the sliding groove and can move within the sliding groove. The sliding groove has an opening communicating with the outside, located on one side of the sliding groove in the first direction. After the abutment 320 is placed in the sliding groove, the opening is sealed by a baffle (not shown in the figure) to restrict the movement of the abutment 320 away from the sliding groove in the bass direction. The baffle and the sliding groove define a second hole 312. A first elastic member 330 is disposed in the second hole 312. The first elastic member 330 and the abutment 320 are arranged sequentially along the direction close to the fixing part 311. The two ends of the first elastic member 330 abut against the groove wall of the sliding groove and the abutment 320, respectively, to provide a force to the abutment 320 in the second direction close to the fixing part 311.

[0074] Reference Figures 3 to 6 , Figure 9 and Figure 10In other embodiments, the counterweight 310 is provided with a second hole 312 extending in a second direction. The abutment 320 is located in the second hole 312 and is able to move within the second hole 312. The counterweight 310 is also provided with a limiting boss 315 located in the second hole 312. The abutment 320 is located in the second hole 312 and is able to move within the second hole 312. The abutment 320 includes a second body 324 and a limiting part 321. The limiting part 321 is connected to the second body 324. The limiting boss 315 is used to abut against the limiting part 321 to limit the movement of the abutment 320 toward the fixing part 311 in the second direction. By abutting against the limiting boss 315 and the limiting part 321, the movement of the abutting member 320 away from the second hole 312 can be restricted. Furthermore, the minimum distance between the abutting member 320 and the fixing part 311 in the second direction can be limited, so that the abutting member 320 can only abut against the locking boss 220 and the reset boss 230 after moving to a certain position, and will not abut against other parts that do not need to be abutted. This reduces the friction force on the counterweight 310 and the abutting member 320 during movement, making the movement of the counterweight 310 and the abutting member 320 smoother, reducing the wear of the abutting member 320, and extending its service life.

[0075] For example, in an embodiment where a first elastic member 330 is provided, a second elastic member 240 is sleeved on the first main body 210. The two ends of the second elastic member 240 abut against the locking boss 220 and the reset boss 230, respectively. When the abutting member 320 is located between the locking boss 220 and the reset boss 230, the abutting member 320 may interfere with the second elastic member 240. By limiting the movement of the abutting member 320 in the second direction through the limiting boss 315 and the limiting part 321, the abutting member 320 can be positioned between the locking boss 220 and the reset boss 230 with a certain distance from the first elastic member 330, so as to solve the interference problem.

[0076] Specifically, the second hole 312 can pass through the counterweight 310 in the second direction to facilitate the insertion of the first elastic member 330 and the abutment member 320 into the second hole 312. Furthermore, the second hole 312 is provided with an internal thread 251 to facilitate the subsequent attachment of pre-tightening components such as bolts into the second hole 312, and to position the pre-tightening component on the side of the first elastic member 330 facing away from the fixing part 311 in the second direction, thereby restricting the movement of the first elastic member 330 and the abutment member 320 out of the second hole 312. The first elastic member 330 can be sleeved on the second body 324 and abut against the limiting part 321, so that the first elastic member 330 and the abutment member 320 are more compactly assembled.

[0077] Reference Figure 2 , Figure 3 and Figure 9In some embodiments, the counterweight 310 is provided with a third hole 313 and a fourth hole 314, both extending along the first direction and sequentially connected along the direction from the reset boss 230 toward the locking boss 220. The locking boss 220 and the reset boss 230 are movable within the third hole 313, and the fixing part 311 is disposed within the fourth hole 314. By providing the fourth hole 314 and the fixing part 311 within it, the counterweight 310 can be fitted and fixed onto the pull tube 420, resulting in a more even force distribution on the pull tube 420. The third hole 313 provides movement space for the abutment 320 and the limiting structure 200.

[0078] Specifically, the fixing part 311 can be a protrusion provided in the fourth hole 314, which provides interference pre-tightening to the pull-out tube 420. Alternatively, the fixing part 311 can be an adhesive layer bonded to the pull-out tube 420. Alternatively, when the pull-out tube 420 is a metal tube, the fixing part 311 can be a connection structure welded to the pull-out tube 420.

[0079] Furthermore, refer to Figure 1 , Figure 2 and Figure 11The counterweight 310 includes a third body 316 and a fourth body 318. A third hole 313 and a fourth hole 314 are defined between the third body 316 and the fourth body 318. The third body 316 and the fourth body 318 are rotatably connected on one side in a second direction, allowing the third body 316 to be either engaged or disengaged. The third body 316 and the fourth body 318 are detachably connected on the other side in the second direction, allowing them to be relatively fixed after being engaged. The third body 316 and the fourth body 318 facilitate the assembly of the counterweight 310. During assembly, the third body 316 and the fourth body 318 are flipped open, so that the pull-out tube 420 is positioned between the third body 316 and the fourth body 318, and the pull-out tube 420 is positioned such that the fourth hole 314 is defined after the third body 316 and the fourth body 318 are engaged. After positioning, the third body 316 and the fourth body 318 are fitted together to clamp the pull-out tube 420. Then, the third body 316 and the fourth body 318 are fixed relative to each other, thus assembling the counterweight 310 with the pull-out tube 420. The detachability of the third body 316 and the fourth body 318 facilitates the assembly of the counterweight 310, allowing adjustment of its position on the pull-out tube 420. Furthermore, flipping the counterweight 310 so that the fourth hole 314 is located between the limiting structure 200 and the third hole 313 prevents the locking boss 220 from interfering with the counterweight 310, preventing the holding member 320 from engaging with the locking boss 220, thereby disabling the hovering and reset functions. Further, fixing the counterweight 310 in the position where it abuts against the locking boss 220 disables the pull-out function of the faucet 400.

[0080] Specifically, the rotational connection between the third body 316 and the fourth body 318 can be achieved through a hinge, or by connecting the third body 316 and the fourth body 318 with a deformable elastic rib 340, so that the third body 316 and the fourth body 318 can rotate apart relative to each other, and can automatically return to the attached state under the action of the elastic rib 340. The detachable connection between the third body 316 and the fourth body 318 can be achieved through the connection of pre-tightening components such as bolts, or by having a slot 319 in one of the third body 316 and the other with a buckle 317, and the detachable connection is achieved by the buckle 317 and the slot 319 engaging.

[0081] Reference Figure 12According to an embodiment of the present invention, the water outlet device 10 includes a faucet 400 and a suspension mechanism 100 as described in the above embodiment. The faucet 400 includes a base 410, a pull-out tube 420, and a water outlet head 430. The base 410 is provided with a mounting hole 411, and the pull-out tube 420 passes through the mounting hole 411. One end of the pull-out tube 420 is connected to the water outlet head 430, and the other end of the pull-out tube 420 is fixedly connected to a fixing part 311. A limiting structure 200 is fixed to the base 410. By applying the suspension mechanism 100 of the present application embodiment, the structure of the suspension mechanism 100 can be simplified while realizing the suspension and reset functions, thereby reducing the number of parts of the water outlet device 10, facilitating the assembly of the water outlet device 10, ensuring the locking effect in the suspension state, and facilitating the use of the pull-out function.

[0082] Specifically, the pull-out pipe 420 can be used as a water outlet pipe for water discharge, or in some embodiments, the water outlet pipe can be another pipe that passes through the pull-out pipe 420.

[0083] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
