The present invention provides a handle device 10.

Referring to fig. 1, 4, 5 and 9, in an embodiment of the present invention, the handle device 10 is used for a faucet 100, the faucet 100 includes a faucet body 20 and a valve core 30 disposed in the faucet body 20, the valve core 30 is connected with a valve rod 40, and the handle device 10 includes a housing 11, a handle 12 and a reset mechanism 13. The housing 11 is for fitting to the faucet body 20; a handle 12 movably mounted to the housing 11 and having an open position and a closed position relative to the housing 11, the handle 12 being adapted to be coupled to the valve stem 40; the return mechanism 13 is provided between the housing 11 and the handle 12, the return mechanism 13 includes an elastic member for providing a return force for moving the handle 12 from the open position toward the closed position, and an adjusting member 133 for adjusting the pre-compression amount of the elastic member.

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 where the valve plug 30 is disposed, wherein the housing 11 and the faucet body 20 can be assembled directly, or can be assembled indirectly through other components (such as the valve plug cover 15), for example, the housing 11 is connected to the valve plug cover 15, and the valve plug cover 15 is assembled to the faucet body 20. The handle 12 is provided with an installation position for the universal valve rod 40, and the valve rod 40 on the valve core 30 can be directly connected with the installation position on the handle 12 without changing the structures of the valve core 30 and the valve rod 40 during assembly. The handle 12 is movably coupled to the housing 11, including but not limited to, by a rotatable connection, a sliding connection, etc., so that the handle 12 can 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 valve rod 40 is moved relative to the valve core 30, so as to open and close 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.

The return mechanism 13 is elastically and telescopically disposed between the housing 11 and the handle 12, the return mechanism 13 includes an elastic member for providing a return force for moving the handle 12 from the open position toward the closed position, and an adjusting member 133 for adjusting a pre-compression amount of the elastic member. The reset mechanism 13 may be mounted in various manners, for example, the reset mechanism 13 is mounted on the housing 11, and the elastic component is elastically abutted to the handle 12; or the reset mechanism 13 is arranged on the handle 12 and enables the elastic component to be elastically abutted with the shell 11; as long as it is ensured that the return mechanism 13 is deformed telescopically to a certain extent when the handle 12 is moved 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 elastic element is compressed and deformed, and when the external force is removed, the elastic element returns to the natural extension direction, and the handle 12 is pushed to return to the closed position by the elastic force of the elastic element. Of course, in some embodiments, it is also possible that when the handle 12 moves from the closed position to the open position, the elastic element is deformed by stretching, and when the external force is removed, the elastic element returns to the natural retraction direction, so that the handle 12 is pulled to return to the closed position by the elastic force of the elastic element.

When the handle device 10 of the present invention is applied to the faucet 100, the time-delay reset function of the faucet 100 can be realized. When the water faucet 100 needs 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 elastic component is deformed under the action of an external force to accumulate elastic potential energy; when the acting force on the handle 12 is removed, the elastic component gradually recovers to deform and releases elastic potential energy, so as to drive the handle 12 to gradually return to the closed position, thereby realizing the delayed reset function of the faucet 100. Therefore, the water faucet 100 can be well applicable to use scenes in public environments, the phenomenon of water leakage caused by the fact that a user forgets to close the water faucet 100 can be avoided, and water resource waste and property loss are avoided. And adjust elastic component's precompression volume through regulating part 133, can change elastic component's elasticity size, and then can realize the regulation of time delay reset time length to satisfy different use scenes, promote the commonality. In addition, because the reset mechanism 13 is completely integrated in the handle device 10, the reset mechanism 13 is not limited by the structures of the faucet body 20 and the valve core 30, and automatic reset can be realized without the aid of the faucet body 20 and the valve core 30, so that the handle device 10 has higher universality and can be universally adapted to various types of faucets 100.

To facilitate the installation of the reset mechanism 13, as shown in fig. 1 and 4, in one embodiment, the handle 12 is provided with an installation hole 1211, a depth direction of the installation hole 1211 is consistent with a stretching direction of the elastic component, the installation hole 1211 has a first port and a second port opposite to each other, the elastic component is partially accommodated in the installation hole, one end of the elastic component extends out from the first port and abuts against the housing 11, the adjusting member 133 is provided at the second port, and the adjusting member 133 can perform position adjustment along the depth direction of the installation hole 1211.

Specifically, in the present embodiment, the handle 12 includes a main body 121 and a handle portion 122, and a mounting hole 1211 extending in the up-down direction may be provided in the main body 121, through the mounting hole 1211, not only the elastic component can be mounted, but also a certain guiding function can be provided for the telescopic movement of the elastic component. The adjusting member 133 is disposed at the second port, and the position of the adjusting member 133 along the depth direction of the mounting hole 1211 is adjusted, so that the pre-compression amount of the elastic component can be adjusted, and the adjustment of the delay reset time can be realized to meet different use scenarios.

In order to facilitate the position adjustment of the adjusting member 133 in the depth direction of the mounting hole 1211, in one embodiment, the adjusting member 133 is threadedly coupled to the mounting hole 1211. Specifically, the adjusting element 133 may be a plug disposed in the mounting hole 1211, and an outer circumferential surface of the plug is in threaded connection with an inner circumferential surface of the mounting hole 1211, so that the adjustment of the mounting position of the adjusting element 133 can be achieved only by screwing, and the adjustment of the delay reset time is further achieved, and the operation is simple and convenient. In order to facilitate the user to use the tool to screw, optionally, the side of the adjusting member 133 facing away from the elastic member 132 is provided with a sinking groove adapted to the screwing tool. Of course, the position of the adjusting member 133 may be adjusted in other manners, for example, in some embodiments, the hole wall of the installation hole 1211 may be provided with a plurality of fastening positions, the fastening positions are arranged along the depth direction of the installation hole 1211, the adjusting member 133 is provided with a clamping portion, and when the position of the adjusting member 133 is adjusted, the clamping portion of the adjusting member 133 only needs to be adjusted to be clamped with a proper fastening position.

To facilitate installation and removal of the reset mechanism 13, optionally, an adjustment member 133 is removably mounted at the second port. During assembly, the elastic component may be inserted into the mounting hole 1211 from the second port of the mounting hole 1211, and then the adjusting component 133 is sealed at the second port, so that the installation is simple and convenient. When the delayed reset function of the faucet 100 is not required to be realized, the delayed reset function can be turned off only by detaching the adjusting member 133 from the second port and detaching the elastic member. Thus, the handle device 10 can be applied to various application scenarios, for example, the handle device can be applied to a faucet 100 that needs to have a time-delay reset function in a public environment, and can also be applied to a faucet 100 that does not need to have a time-delay reset function in a household environment, thereby further improving the versatility of the handle device 10. To facilitate the fitting of the adjusting member 133 into the second port, an outer circumferential surface of one end of the adjusting member 133 adjacent to the elastic member 132 is provided with a tapered surface.

As shown in fig. 1 and 4, in one embodiment, the elastic component includes an abutting member 131 and an elastic member 132, one end of the elastic member 132 abuts against the housing 11 through the abutting member 131, and the other end of the elastic member 132 abuts against the adjusting member.

Specifically, in the present embodiment, one end of the abutting member 131 is disposed in the mounting hole 1211, and the other end of the abutting member extends out of the first port to abut against the housing 11. The propping element 131 is kept in propping contact with the shell 11 under the action of the elastic element 132, when the handle 12 is opened, the propping element 131 moves along the shell 11, the shell 11 applies pressure to the propping element 131, and the propping element 131 drives the elastic element 132 to compress, deform and 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 abutting member 131, so that the abutting member 131 is reversely reset along the housing 11. The elastic component is stretched and deformed in a manner of matching the abutting piece 131 with the elastic piece 132, and the elastic component is simple in structure and low in cost. The elastic member 132 includes, but is not limited to, a spring plate, or an elastic rubber column.

Further, the propping element 131 is provided with a receiving cavity for receiving the elastic element 132. Specifically, the abutting member 131 is a cylindrical structure with an open end and a closed end, the closed end of the abutting member 131 abuts against the stopping member 114, a receiving cavity is formed inside the abutting member 131, and the open end of the abutting member 131 is used for installing the elastic member 132 into the receiving 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 mechanism 13 is more compact, the occupied space is smaller, and the miniaturization of the handle device 10 is facilitated. And the elastic member 132 can be prevented from inclining by limiting and guiding the expansion of the elastic member 132 to a certain extent through the accommodating cavity.

In order to prevent the abutting member 131 from coming 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 one end of the abutting member 131, which is disposed in the mounting hole 1211, and a limiting step 1212 is disposed on an inner peripheral edge of the first port, where the limiting step 1212 is configured to be in limiting fit with the boss 1311. When the abutting part 131 extends to the limit position, the limit step 1212 at the first port is in limit abutment with the boss 1311 of the abutting part 131, so as to prevent the abutting part 131 from coming out of the first port.

Referring to fig. 1 and 5, in one embodiment, the handle 12 includes a main body portion 121 and a handle portion 122 connected to the main body portion 121, the housing 11 is provided with an accommodating cavity 111 for accommodating the main body portion 121, and an avoiding opening 112 communicated with the accommodating cavity 111 for moving the handle 12, the main body portion 121 is movably connected to the housing 11, the reset mechanism 13 is mounted on the main body portion 121, and the handle portion 122 extends out of the housing 11 and can swing back and forth along the extending direction of the elastic component.

In the present embodiment, the handle 12 includes a main body portion 121 and a handle portion 122, wherein the main body portion 121 is mainly used for assembling and connecting with the housing 11, the main body portion 121 can also be used as a mounting carrier of the reset mechanism 13, the handle portion 122 is in a shape of a long arm extending toward one side of the main body portion 121, and the handle portion 122 extends out of the housing 11 for facilitating the operation of the user. The extension direction of the handle 122 is substantially perpendicular to the extension direction of the elastic assembly, and the handle 122 can swing back and forth along the extension direction of the elastic assembly under the action of external force. For example, in the embodiment, the handle device 10 is installed on the top of the faucet body 20, the elastic component can be extended and retracted in the up-down direction, accordingly, the handle 122 can be swung back and forth in the up-down direction relative to the housing 11, and when the faucet 100 needs to be opened, the handle 122 only needs to be lifted up; when the force is removed, handle 122 may be swung down to reset to shut off faucet 100. In some embodiments, the handle assembly 10 is mounted on the side of the faucet body 20, the elastic component can be extended and retracted along the front-back direction, 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 forward; when the force is removed, handle 122 may be swung back to reset to shut off faucet 100. In this embodiment, the handle 12 is movably connected to the housing 11 through the main body 121, so that the handle 122 can swing back and forth along the extending direction of the elastic component relative to the housing 11, and thus the handle device 10 forms a long-arm lever structure, which is easy and labor-saving to use and is convenient for the elderly and children to use.

Referring to fig. 4 and 5, in one embodiment, the housing 11 includes a stopper 114 disposed in the receiving cavity 111, and the stopper 114 has a first stop surface 1141 and a second stop surface 1142 disposed obliquely to the first stop surface 1141. The first stop surface 1141 may be disposed in a plane, and the second stop surface 1142 is disposed in an inclined plane inclined with respect to the first stop surface 1141. When the handle 12 is in the closed position, the resilient member is extended and abuts the first stop surface 1141 such that the handle 12 is maintained in a stable closed position without external forces. When a force is applied to handle 12 toward the open position, the resilient member may move from first stop surface 1141 to second stop surface 1142 and may be gradually compressed by second stop surface 1142. When the handle 12 is in the open position, the resilient member is in a compressed state and abuts the second stop surface 1142. When the external force is removed, the elastic member gradually extends and moves along the second stop surface 1142 to the first stop surface 1141, thereby implementing the delayed reset function of the handle device 10.

In order to facilitate the assembly of the handle 12 and the housing 11 and to enable the handle 12 to swing back and forth along a predetermined direction, in some embodiments, one of the inner wall surface of the accommodating cavity 111 and the outer side surface of the main body 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 main body 121 and 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 cavity 111 of the housing 11, the protrusion 123 is provided on the outer side surface of the body portion 121 of the handle 12, and when assembling, the protrusion 123 is snapped 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 may move from the first end to the second end of the track groove 113; when the external force is removed, the handle 12 moves towards the closed position under the action of the reset mechanism 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 accurately switched between the open position and the closed position by the matching guiding action of the track groove 113 and the convex part 123. In order to further ensure the reliability of the assembly of the handle 12 and the housing 11, optionally, two opposite sides of the accommodating cavity 111 are respectively provided with the track grooves 113, two opposite sides of the main body portion 121 are respectively provided with the protrusions 123, and the two protrusions 123 are slidably engaged with the two track grooves 113 in a one-to-one correspondence manner. Of course, in some embodiments, the positions of the track groove 113 and the protrusion 123 can be interchanged, and the protrusion 123 is disposed on the inner wall surface of the accommodating cavity 111 of the housing 11, and the track groove 113 is disposed on the outer side surface of the main body portion 121 of the handle 12. The shape of the track groove 113 may be designed according to a specific motion track of the handle 12, and optionally, in this embodiment, the track groove 113 is an arc-shaped groove, and the handle 12 can rotate around an arc center of the track groove 113 relative to the housing 11.

Further, as shown in fig. 4 and 5, referring to fig. 1, 4 and 6, in order to facilitate the assembly of the handle 12 with the valve stem 40, in one embodiment, the handle 12 is provided with a socket 124 into which the valve stem 40 is inserted, and a connection hole 125 into which the fastener 14 is inserted, the connection hole 125 extending in a radial direction of the socket 124 and communicating with the socket 124, and the fastener 14 is used for locking the valve stem 40 in the socket 124. During assembly, one end of the valve rod 40, which is far away from the valve core 30, is inserted into the insertion hole 124 of the main body part 121, the fastener 14 is inserted into the connecting hole 125, and the end part of the fastener 14 is used for jacking the valve rod 40, so that the assembly is simple and convenient. And the handle 12 is provided with the universal mounting position, so that the valve rod 40 can be quickly mounted without changing the structure of the valve rod 40 of the water faucet 100. To facilitate assembly of the fastener 14, the fastener 14 may alternatively be a threaded fastener 14 such as a screw or bolt, and the connecting hole 125 is a threaded hole adapted to the fastener 14.

In addition, in the prior art, some faucets 100 with the delayed reset function often cannot realize the switching of the hot and cold water paths, and are only suitable for a single water path.
