The present utility model proposes a handle device 10.

Referring to fig. 1, 4, 5 and 9, in one embodiment of the present utility model, the handle device 10 is used for a faucet 100, the faucet 100 includes a faucet body 20 and a switch assembly 30 disposed in the faucet body 20, the switch assembly 30 is connected with a control lever 40, and the handle device 10 includes a housing 11, a handle 12 and a reset assembly 13. The housing 11 is for fitting to the tap body 20; the handle 12 is movably mounted on the housing 11 and has an open position and a closed position relative to the housing 11, the handle 12 being provided with a mounting location for connecting the control lever 40; a return assembly 13 is resiliently telescopically arranged between the handle 12 and the housing 11, the return assembly 13 being adapted to provide a return force for moving the handle 12 from the open position towards the closed position.

Specifically, when the handle device 10 is used in the faucet 100, the housing 11 is assembled to the end of the faucet body 20 provided with the switch assembly 30, wherein the housing 11 and the faucet body 20 may be directly assembled, or may be indirectly assembled through other components (such as the gland 15), for example, the housing 11 is connected to the gland 15, and the gland 15 is assembled to the faucet body 20. The handle 12 is provided with a mounting location for the universal control lever 40, and the control lever 40 on the switch assembly 30 can be directly connected with the mounting location on the handle 12 without changing the structures of the switch assembly 30 and the control lever 40 during assembly. The switch assembly 30 may be a valve core disposed in the faucet body 20, the control lever 40 may be a valve stem connected to the valve core, and the handle 12 may be movably connected to the housing 11 by a rotational connection, a sliding connection, or the like, so that the handle 12 may reciprocate between an open position and a closed position relative to the housing 11. As shown in fig. 6 and 7, when the handle 12 is moved, the control lever 40 is moved relative to the switch assembly 30, thereby opening and closing the faucet 100, when the handle 12 is in the open position, the faucet 100 is opened, and when the handle 12 is in the closed position, the faucet 100 is closed.

A return assembly 13 is resiliently telescopically arranged between the housing 11 and the handle 12, the return assembly 13 being adapted to provide a return force for moving the handle 12 from the open position towards the closed position. The reset assembly 13 is mounted in various manners, for example, the reset assembly 13 is mounted on the shell 11 and elastically abuts against the handle 12; or the reset component 13 is arranged on the handle 12 and elastically abuts against the shell 11; so long as it is ensured that the reset assembly 13 is capable of undergoing a certain amount of telescopic deformation when the handle 12 moves relative to the housing 11. For example, as shown in fig. 4 and 5, in the present embodiment, when the handle 12 moves from the closed position to the open position, the restoring member 13 is compressively deformed, and when the external force is removed, the restoring member 13 returns to the deformed state in the natural extension direction, and the handle 12 is pushed to return to the closed position by the elastic force of the restoring member 13. Of course, in some embodiments, when the handle 12 moves from the closed position to the open position, the reset assembly 13 is stretched and deformed, and when the external force is removed, the reset assembly 13 returns to the deformed state toward the natural retraction direction, and the handle 12 is pulled to return to the closed position by the elastic force of the reset assembly 13.

When the handle device 10 of the utility model is applied to the faucet 100, the delay reset function of the faucet 100 can be realized. When the faucet 100 is needed to be used, a user applies a certain acting force to the handle 12 to enable the handle 12 to move from the closed position to the open position, and in the process, the reset assembly 13 deforms under the action of external force to store elastic potential energy; when the acting force on the handle 12 is removed, the reset component 13 gradually recovers the deformation and releases the elastic potential energy, so as to drive the handle 12 to gradually return to the closed position, thereby realizing the time-delay reset function of the faucet 100. Therefore, the faucet 100 can be well suitable for use in public environment, and can avoid water leakage caused by the fact that a user forgets to close the faucet 100, and avoid water resource waste and property loss. In addition, since the reset assembly 13 is completely integrated in the handle device 10, the reset assembly 13 is not limited by the structures of the faucet body 20 and the switch assembly 30, and automatic reset can be realized without the faucet body 20 and the switch assembly 30, so that the handle device 10 has higher universality and can be universally adapted to various types of faucets 100.

Referring to fig. 1 and 5, in one embodiment, the handle 12 includes a main body 121 and a handle portion 122 connected to the main body 121, the housing 11 is provided with a receiving cavity 111 for receiving the main body 121, and an escape opening 112 communicating with the receiving cavity 111 for moving the handle 12, the main body 121 is movably connected to the housing 11, the reset assembly 13 is elastically and telescopically arranged between the main body 121 and the housing 11, and the handle portion 122 extends out of the housing 11 and can reciprocate along the telescopic direction of the reset assembly 13.

In this embodiment, the handle 12 includes a main body 121 and a handle 122, where the main body 121 is mainly used for being assembled with the housing 11, and meanwhile, the main body 121 may be used as an installation carrier of the reset assembly 13, the handle 122 is in a long arm shape extending toward one side of the main body 121, and the handle 122 protrudes out of the housing 11 to facilitate the operation of a user. The extension direction of the handle 122 is substantially perpendicular to the extension direction of the reset assembly 13, and the handle 122 can swing reciprocally along the extension direction of the reset assembly 13 under the action of external force. For example, in the present embodiment, the handle device 10 is mounted on the top of the faucet body 20, the reset assembly 13 can be extended and retracted along the up-down direction, and accordingly, the handle 122 can be reciprocally swung along the up-down direction relative to the housing 11, and when the faucet 100 needs to be opened, only the handle 122 needs to be lifted upwards; when the external force is removed, the handle 122 may swing downward to reset to close the faucet 100. In some embodiments, the handle device 10 is mounted on the side of the faucet body 20, the reset assembly 13 can be extended and retracted along the front-back direction, and accordingly, the handle 122 can be reciprocally swung along the front-back direction relative to the housing 11, and when the faucet 100 needs to be opened, only the handle 122 needs to be swung forwards; when the external force is removed, the handle 122 may swing back to reset to close the faucet 100. In this embodiment, the handle 12 is movably connected with the housing 11 through the main body 121, so that the handle 122 can swing reciprocally along the extension direction of the reset assembly 13 relative to the housing 11, and thus, the handle device 10 forms a long-arm lever structure, which is easier and more labor-saving to use and is convenient for the elderly and children to use.

To facilitate assembly of the handle 12 and the housing 11 while enabling the handle 12 to reciprocate in a predetermined direction, in some embodiments, one of an inner wall surface of the accommodating chamber 111 and an outer side surface of the body portion 121 is provided with a track groove 113, and the other is provided with a protrusion 123, and the protrusion 123 is movably disposed in the track groove 113 to movably connect the body portion 121 with the housing 11.

For example, as shown in fig. 1 to 3, in the present embodiment, the track groove 113 is provided on the inner wall surface of the accommodating chamber 111 of the housing 11, the protrusion 123 is provided on the outer side surface of the main body 121 of the handle 12, and when assembling, the protrusion 123 is engaged into the track groove 113, so that the handle 12 and the housing 11 can be assembled, and the operation is simple and convenient. When the faucet 100 is turned on, the user applies a force to the handle 12 toward the open position, and the protrusion 123 is movable from the first end to the second end of the track groove 113; when the external force is removed, the handle 12 moves toward the closed position under the action of the reset assembly 13, and the protrusion 123 can move from the second end to the first end of the track groove 113. The handle 12 can be precisely switched between the open position and the closed position by the mating guiding action of the track grooves 113 and the protrusions 123. In order to further ensure the assembly reliability of the handle 12 and the housing 11, optionally, track grooves 113 are respectively provided on opposite sides of the accommodating cavity 111, and protrusions 123 are respectively provided on opposite sides of the main body 121, and the two protrusions 123 are slidably engaged with the two track grooves 113 in a one-to-one correspondence. Of course, in some embodiments, the positions of the track groove 113 and the protrusion 123 may be interchanged, the protrusion 123 is provided on the inner wall surface of the accommodating cavity 111 of the housing 11, and the track groove 113 is provided on the outer side surface of the main body 121 of the handle 12, which may achieve the above-mentioned effects. The shape of the track groove 113 may be designed according to a specific movement track of the handle 12, for example, in this embodiment, the handle 12 may swing along an arc track relative to the housing 11, and accordingly, the track groove 113 is disposed in an arc groove.

Referring to fig. 4 and 5, in one embodiment, the housing 11 includes a stopper 114 disposed in the accommodating cavity 111, the reset assembly 13 is elastically and telescopically mounted on the main body 121, and one end of the reset assembly 13 abuts against the stopper 114. Specifically, the housing 11 may include a housing body and a stopper 114, the housing body is hollow and cylindrical, a receiving cavity 111 is formed in the housing body, and a top surface and a side surface of the housing body are provided with a relief opening 112 for the handle 12 to move. The stopper 114 is provided to extend from a side of the top of the housing 11 toward the inside of the accommodation chamber 111. When the handle 12 is assembled with the housing 11, the main body 121 of the handle 12 is disposed in the accommodating cavity 111, the reset assembly 13 is mounted on the main body 121, and one end of the reset assembly 13 is elastically abutted against the stop member 114. When the handle 12 is rotated to the open position, the return assembly 13 can move along with the handle 12, and the return assembly 13 is compressively deformed by the stopper 114 due to the restriction of the stopper 114. When the force applied to the handle 12 is removed, the reset assembly 13 gradually resumes its shape and moves in the opposite direction along the stop 114 to bring the handle 12 to reset automatically.

Further, as shown in fig. 4 and 5, the stopper 114 has a first stopper surface 1141 and a second stopper surface 1142 disposed obliquely to the first stopper surface 1141. The first stop surface 1141 may be disposed in a plane, and the second stop surface 1142 is disposed in a slope inclined with respect to the first stop surface 1141. When the handle 12 is in the closed position, the reset assembly 13 is in an extended state and abuts the first stop surface 1141, so that the handle 12 can be maintained in a stable closed position without external force. When a force is applied to handle 12 to move toward the open position, return assembly 13 may move from first stop surface 1141 to second stop surface 1142 and be progressively compressed by second stop surface 1142. When the handle 12 is in the open position, the reset assembly 13 is in a compressed state and abuts the second stop surface 1142. When the external force is removed, the reset assembly 13 gradually expands and moves along the second stop surface 1142 to the first stop surface 1141, thereby implementing the time-lapse reset function of the handle apparatus 10.

In order to facilitate the installation of the reset assembly 13, as shown in fig. 1 and 4, in one embodiment, the handle 12 is provided with a mounting hole 1121 for accommodating the reset assembly 13, the depth direction of the mounting hole 1211 is consistent with the telescopic direction of the reset assembly 13, the housing is provided with a stop 114, the mounting hole 1211 is provided with a first port, and one end of the reset assembly 13 extends from the first port and abuts against the stop 114. For example, in the present embodiment, the handle 12 includes a main body 121 and a shank 122, a mounting hole 1211 extending in the up-down direction may be provided in the main body 121, a top end of the mounting hole 1211 forms a first port, the reset assembly 13 is mounted in the mounting hole 1211, and a top end of the reset assembly 13 may protrude from the first port to abut against the stopper 114. By providing the mounting hole 1211 in the body portion 121, not only can the reset module 13 be mounted, but also the telescopic movement of the reset module 13 can be guided to a certain extent.

The reset assembly 13 can be realized in various modes, as long as the telescopic deformation can be realized. As shown in fig. 1 and 4, in one embodiment, the reset assembly 13 includes an abutment member 131 and an elastic member 132, one end of the abutment member 131 is disposed in the mounting hole 1211, the other end extends out of the first port to abut against the stop member 114, and the elastic member 132 is disposed in the mounting hole 1211 and abuts against a side of the abutment member 131 facing away from the stop member 114. In the present embodiment, the propping member 131 keeps abutting against the stop member 114 under the action of the elastic member 132, when the handle 12 is opened, the propping member 131 moves along the stop member 114, the stop member 114 applies pressure to the propping member 131, and the propping member 131 drives the elastic member 132 to compress and deform to store elastic potential energy; when the external force is removed, the elastic member 132 releases the elastic potential energy to gradually extend to the initial state, and applies a rebound force to the abutment member 131, so that the abutment member 131 is reversely reset along the stop member 114. The telescopic deformation of the reset assembly 13 is realized by adopting the mode of matching the propping piece 131 and the elastic piece 132, the structure is simple, and the cost is lower. The elastic member 132 includes, but is not limited to, a spring plate, or an elastic rubber column.

Optionally, an end of the abutment member 131 facing away from the stop member 114 is provided with a receiving cavity for receiving the elastic member 132. Specifically, the propping member 131 has a cylindrical structure with one end open and one end closed, the closed end of the propping member 131 is propped against the stop member 114, a containing cavity is formed inside the propping member 131, and the open end of the propping member 131 is used for installing the elastic member 132 into the containing cavity. In this way, the elastic member 132 can be accommodated in the inner space of the abutting member 131, so that the overall structure of the reset assembly 13 is more compact, the occupied space is smaller, and the miniaturization of the handle device 10 is facilitated. And the accommodating cavity can play a certain limiting and guiding role on the expansion and contraction of the elastic piece 132, so that the elastic piece 132 is prevented from tilting.

In order to avoid the abutment member 131 from falling out of the mounting hole 1211, as shown in fig. 1 and 4, optionally, a boss 1311 is disposed on an outer peripheral surface of an end of the abutment member 131 disposed in the mounting hole 1211, and a limit step 1212 is disposed on an inner peripheral edge of the first port, and the limit step 1212 is configured to be in limit fit with the boss 1311. When the propping piece 131 extends to the limit position, the limit step 1212 at the first port is in limit abutment with the boss 1311 of the propping piece 131, so as to prevent the propping piece 131 from being separated from the first port.

In one embodiment, as shown in fig. 4, the end of the mounting hole 1211 facing away from the first port is provided with a second port, and the reset assembly 13 further includes a blocking plug 133 mounted at the second port, and the end of the elastic member 132 facing away from the abutting member 131 abuts against the blocking plug 133.

In this embodiment, during assembly, the abutting member 131 and the elastic member 132 can be sequentially inserted into the mounting hole 1211 from the second port of the mounting hole 1211, one end of the abutting member 131 extends from the first port, and the blocking plug 133 is blocked at the second port, so that the operation is simple and convenient, and the assembly of the reset assembly 13 is convenient. When the time delay reset function of the faucet 100 is not required, the time delay reset function can be turned off by only removing the reset assembly 13 from the mounting hole 1211 or separately removing the elastic member 132. In this way, the handle device 10 can be suitable for various application scenarios, for example, can be applied to a faucet 100 with a time-delay reset function in a public environment, and can also be applied to a faucet 100 without a time-delay reset function in a household environment, thereby further improving the universality of the handle device 10. To facilitate the fitting of the blocking plug 133 into the second port, the outer peripheral surface of the blocking plug 133 near one end of the elastic member 132 is provided in a tapered surface.

In addition, in the prior art, some faucets 100 with a delayed reset function often cannot be adjusted in the length of the delayed reset time. If the delayed reset time is too short, the tap 100 is automatically reset and closed in the water using process, so that the user experience is affected; if the time delay reset time is too long, the faucet 100 needs to be reset and closed for a long time after the user uses the faucet, which causes unnecessary water resource waste.

To enable delayed reset time adjustment of the handle assembly 10 and faucet 100, in one embodiment, the position of the plug 133 along the depth of the mounting hole 1211 is adjustable. Thus, the user only needs to adjust the position of the blocking plug 133 along the hole depth direction of the mounting hole 1211, and then can adjust the compression amount of the elastic member 132 through the blocking plug 133, so as to realize the adjustment of the delayed reset time, so as to meet different use scenes.

There are various ways of achieving the position adjustment of the blocking plug 133, and as shown in fig. 4, in an embodiment, the outer circumferential surface of the blocking plug 133 is screwed with the inner circumferential surface of the mounting hole 1211. So, only need through the mode of screwing up shutoff stopper 133, just can realize the mounted position adjustment of shutoff stopper 133, and then realize time adjustment that resets of time delay, easy operation is convenient. To facilitate screwing by the user using the tool, the face of the closure plug 133 facing away from the elastic element 132 is optionally provided with a countersink adapted to the screwing tool.
