[0042] The present application provides a handle device 10.

[0043] Please refer to Figure 1 , Figure 4 , Figure 5 and Figure 9 In an embodiment of the present application, the handle device 10 is used for a faucet 100, the faucet 100 includes a faucet body 20 and a valve core 30 arranged in the faucet body 20, the valve core 30 is connected with a valve rod 40, the handle device 10 includes a housing 11, a handle 12 and a reset mechanism 13. The housing 11 is used for assembling to the faucet body 20; the handle 12 is movably mounted to the housing 11 and has an opening position and a closing position relative to the housing 11, the handle 12 is used for connecting the valve rod 40; the reset mechanism 13 is arranged between the housing 11 and the handle 12, the reset mechanism 13 includes an elastic assembly and an adjusting piece 133, the elastic assembly is used for providing a reset force for moving the handle 12 from the opening position to the closing position, and the adjusting piece 133 is used for adjusting the pre-compression amount of the elastic assembly.

[0044] Specifically, when the handle device 10 is used for the faucet 100, the housing 11 is assembled to one end of the faucet body 20 provided with the valve core 30, wherein the housing 11 and the faucet body 20 can be directly assembled, or indirectly assembled through other components (for example, a valve core gland 15), for example, the housing 11 is connected with the valve core gland 15, and the valve core gland 15 is assembled to the faucet body 20. The handle 12 is provided with a mounting position compatible with the valve rod 40, and during assembly, without changing the structure of the valve core 30 and the valve rod 40, the valve rod 40 on the valve core 30 can be directly connected with the mounting position on the handle 12. The handle 12 and the housing 11 are movably connected by means of, but not limited to, rotating connection, sliding connection and the like, so that the handle 12 can reciprocate between the opening position and the closing position relative to the housing 11. For example, Figure 6 and Figure 7As shown, when the handle 12 is moved, the valve stem 40 is moved relative to the valve core 30, thereby realizing the opening and closing of the faucet 100. When the handle 12 is in the opening position, the faucet 100 is opened; when the handle 12 is in the closing position, the faucet 100 is closed.

[0045] The reset mechanism 13 is elastically extendable and contractable between the housing 11 and the handle 12. The reset mechanism 13 comprises an elastic assembly and an adjusting member 133. The elastic assembly is configured to provide a reset force for moving the handle 12 from the opening position towards the closing position. The adjusting member 133 is configured to adjust the pre-compression amount of the elastic assembly. The reset mechanism 13 can be installed in various forms. For example, the reset mechanism 13 is installed on the housing 11 and the elastic assembly is in elastic abutment with the handle 12. Alternatively, the reset mechanism 13 is installed on the handle 12 and the elastic assembly is in elastic abutment with the housing 11. As long as the reset mechanism 13 can be deformed elastically when the handle 12 is moved relative to the housing 11, any installation form is acceptable. For example, as shown in FIG. 2, the reset mechanism 13 is installed on the housing 11 and the elastic assembly is in elastic abutment with the handle 12. Figure 4 and Figure 5 As shown, in the present embodiment, when the handle 12 is moved from the closing position to the opening position, the elastic assembly is compressed and deformed. When the external force is removed, the elastic assembly recovers the deformation towards the natural extension direction, thereby pushing the handle 12 to return to the closing position by the elastic force of the elastic assembly. Of course, in some embodiments, the elastic assembly can be stretched and deformed when the handle 12 is moved from the closing position to the opening position. When the external force is removed, the elastic assembly recovers the deformation towards the natural retraction direction, thereby pulling the handle 12 to return to the closing position by the elastic force of the elastic assembly.

[0046] When the handle device 10 of the present application is applied to the faucet 100, the delay reset function of the faucet 100 can be realized. When the faucet 100 needs to be used, the user only needs to exert a certain force on the handle 12 to move the handle 12 from the closed position to the open position, and in this process, the elastic component is deformed under the action of external force to accumulate elastic potential energy; when the force on the handle 12 is removed, the elastic component gradually recovers the deformation and releases the elastic potential energy, thereby driving the handle 12 to gradually return to the closed position, so as to realize the delay reset function of the faucet 100. In this way, the faucet 100 can be well applied to the use scene in a public environment, and the "running water" phenomenon caused by the user forgetting to close the faucet 100 can be avoided, and water resource waste and property loss can be avoided. And by adjusting the pre-compression amount of the elastic component by the adjusting piece 133, the elastic force of the elastic component can be changed, and the length of the delay reset time can be adjusted to meet different use scenes and improve the versatility. In addition, since the reset mechanism 13 is completely integrated in the handle device 10, the reset mechanism 13 is not limited by the structure of the faucet body 20 and the valve core 30, and the automatic reset can be realized without the help of the faucet body 20 and the valve core 30, so that the handle device 10 has higher versatility and can be universally adapted to various types of faucets 100.

[0047] In order to facilitate the installation of the reset mechanism 13, as shown in Figure 1 and Figure 4 In one embodiment, the handle 12 is provided with a mounting hole 1211, the hole depth direction of the mounting hole 1211 is consistent with the extension direction of the elastic component, the mounting hole 1211 has opposite first and second ports, the elastic component is partially accommodated in the mounting hole, one end of the elastic component extends from the first port and abuts against the housing 11, and the adjusting piece 133 is arranged at the second port and can be adjusted in position along the hole depth direction of the mounting hole 1211.

[0048] Specifically, in the present embodiment, the handle 12 includes a main body portion 121 and a handle portion 122, and the mounting hole 1211 extending in the up-down direction can be arranged in the main body portion 121. The mounting hole 1211 can not only be used to install the elastic component, but also can play a certain guiding role in the extension and retraction movement of the elastic component. The adjusting piece 133 is arranged at the second port, and by adjusting the position of the adjusting piece 133 along the hole depth direction of the mounting hole 1211, the pre-compression amount of the elastic component can be adjusted to realize the adjustment of the delay reset time and meet different use scenes.

[0049] In order to facilitate the position adjustment of the adjusting member 133 along the hole depth direction of the mounting hole 1211, in an embodiment, the adjusting member 133 is threadedly connected with the mounting hole 1211. Specifically, the adjusting member 133 can be a plug arranged in the mounting hole 1211, and the outer peripheral surface of the plug is threadedly connected with the inner peripheral surface of the mounting hole 1211. In this way, the position adjustment of the adjusting member 133 can be achieved by screwing, and the delay reset time adjustment is achieved, which is simple and convenient to operate. In order to facilitate the user to use the tool to screw, optionally, the surface of the adjusting member 133 away from the elastic member 132 is provided with a recess groove matched with the screwing tool. Of course, the position adjustment of the adjusting member 133 can also be achieved by other forms, for example, in some embodiments, a plurality of buckling positions can be arranged on the hole wall of the mounting hole 1211 along the hole depth direction of the mounting hole 1211, and the adjusting member 133 is provided with a clamping portion. When adjusting the position of the adjusting member 133, only the clamping portion of the adjusting member 133 needs to be adjusted to be clamped with the appropriate buckling position.

[0050] In order to facilitate the installation and disassembly of the reset mechanism 13, optionally, the adjusting member 133 can be detachably installed at the second port. When assembling, the elastic assembly can be inserted into the mounting hole 1211 from the second port of the mounting hole 1211, and then the adjusting member 133 is plugged at the second port, which is simple and convenient to install. When the delay reset function of the faucet 100 is not needed, the adjusting member 133 is only needed to be removed from the second port, and the elastic assembly is disassembled, so that the delay reset function is closed. In this way, the handle device 10 can be applied to various application scenarios, for example, it can be applied to the faucet 100 with delay reset function in public environment, and it can also be applied to the faucet 100 without delay reset function in household environment, which further improves the versatility of the handle device 10. In order to facilitate the assembly of the adjusting member 133 into the second port, the outer peripheral surface of the end of the adjusting member 133 close to the elastic member 132 is provided in a tapered surface.

[0051] As shown in Figure 1 and Figure 4 In an embodiment, the elastic assembly includes the abutting member 131 and the 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.

[0052] Specifically, in the present embodiment, one end of the abutting member 131 is placed in the mounting hole 1211, and the other end extends out of the first port to abut against the shell 11. The abutting member 131 is kept in abutment with the shell 11 under the action of the elastic member 132. When the handle 12 is opened, the abutting member 131 moves along the shell 11, and the shell 11 exerts pressure on the abutting member 131, thereby causing the abutting member 131 to drive the elastic member 132 to compress and deform to store elastic potential energy. After the external force is removed, the elastic member 132 releases the elastic potential energy to gradually expand to the initial state and exerts a rebounding force on the abutting member 131 to cause the abutting member 131 to reversely reset along the shell 11. The abutting member 131 and the elastic member 132 are used in combination to realize the expansion and deformation of the elastic assembly, which is simple in structure and low in cost. The elastic member 132 includes, but is not limited to, a spring, a spring sheet, or an elastic rubber column.

[0053] Further, the abutting member 131 is provided with a receiving cavity for accommodating the elastic member 132. Specifically, the abutting member 131 has a columnar structure with one end open and the other end closed. The closed end of the abutting member 131 abuts against the stopper 114, and the inside of the abutting member 131 forms the receiving cavity. The open end of the abutting member 131 is used to mount the elastic member 132 into the receiving cavity. In this way, the elastic member 132 can be accommodated in the internal space of the abutting member 131, so that the overall structure of the reset mechanism 13 is more compact and occupies less space, which is conducive to the miniaturization of the knob device 10. Moreover, the receiving cavity can limit and guide the expansion of the elastic member 132, avoiding the inclination of the elastic member 132.

[0054] In order to avoid the abutting member 131 from being pulled out of the mounting hole 1211, as shown in Figure 1 and Figure 4 , optionally, the outer peripheral surface of one end of the abutting member 131 placed in the mounting hole 1211 is provided with a boss 1311, and the inner periphery of the first port is provided with a limiting step 1212. The limiting step 1212 is used to limit the cooperation with the boss 1311. When the abutting member 131 extends to the limit position, the limiting step 1212 at the first port limits and abuts against the boss 1311 of the abutting member 131 to prevent the abutting member 131 from being pulled out of the first port.

[0055] Please refer to Figure 1 and Figure 5 , in one of the embodiments, the handle 12 includes a main body portion 121 and a handle portion 122 connected with the main body portion 121. The shell 11 is provided with an accommodating cavity 111 for accommodating the main body portion 121, and a avoiding port 112 in communication with the accommodating cavity 111 for the handle 12 to move. The main body portion 121 is movably connected with the shell 11, the reset mechanism 13 is mounted on the main body portion 121, and the handle portion 122 extends out of the shell 11 and can swing back and forth along the expansion direction of the elastic assembly.

[0056] In the embodiment, the handle 12 comprises a main body portion 121 and a handle portion 122, wherein the main body portion 121 is mainly used for assembly connection with the shell 11, and the main body portion 121 can also be used as a mounting carrier of the reset mechanism 13; the handle portion 122 is in the shape of a long arm extending towards one side of the main body portion 121, and the handle portion 122 extends out of the shell 11 to facilitate user operation. The extending direction of the handle portion 122 is generally perpendicular to the stretching direction of the elastic assembly, and under the action of an external force, the handle portion 122 can reciprocate in the stretching direction of the elastic assembly. For example, in the embodiment, the handle device 10 is mounted on the top of the faucet body 20, the elastic assembly can stretch in the up-down direction, and correspondingly, the handle portion 122 can reciprocate in the up-down direction relative to the shell 11; when it is needed to open the faucet 100, the handle portion 122 only needs to be lifted upwards; when the external force is removed, the handle portion 122 can swing downwards 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 elastic assembly can stretch in the front-back direction, and correspondingly, the handle portion 122 can reciprocate in the front-back direction relative to the shell 11; when it is needed to open the faucet 100, the handle portion 122 only needs to be swung forwards; when the external force is removed, the handle portion 122 can swing backwards to reset to close the faucet 100. In the embodiment, the handle 12 is movably connected to the shell 11 through the main body portion 121, so that the handle portion 122 can reciprocate in the stretching direction of the elastic assembly relative to the shell 11; in this way, the handle device 10 forms a long-arm lever structure, which is more convenient and labor-saving to use, and is convenient for the elderly and children to use.

[0057] Please refer to Figure 4 and Figure 5 In one of the embodiments, the shell 11 comprises a stopper 114 arranged in the accommodating cavity 111, and the stopper 114 has a first stop surface 1141 and a second stop surface 1142 arranged obliquely relative to the first stop surface 1141. The first stop surface 1141 can be arranged in the shape of a plane, and the second stop surface 1142 is arranged in the shape of an inclined surface obliquely relative to the first stop surface 1141. When the handle 12 is in the closed position and the elastic assembly is in the stretched state and abuts against the first stop surface 1141, the handle 12 can be kept in the stable closed position without the action of an external force. When an external force is applied to the handle 12 to move towards the open position, the elastic assembly can move from the first stop surface 1141 to the second stop surface 1142 and be gradually compressed under the action of the second stop surface 1142. When the handle 12 is in the open position and the elastic assembly is in the compressed state and abuts against the second stop surface 1142. When the external force is removed, the elastic assembly is gradually stretched and moves along the second stop surface 1142 to the first stop surface 1141, thereby realizing the time-delay reset function of the handle device 10.

[0058] In order to facilitate the assembly of the handle 12 and the shell 11, and at the same time enable the handle 12 to swing back and forth along a preset 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, which is movably arranged in the track groove 113 to movably connect the main body 121 and the shell 11.

[0059] For example, as shown in Figures 1 to 3 , in the present embodiment, the inner wall surface of the accommodating cavity 111 of the shell 11 is provided with a track groove 113, and the outer side surface of the main body 121 of the handle 12 is provided with a protrusion 123. When assembling, the protrusion 123 is clamped into the track groove 113, thereby realizing the assembly of the handle 12 and the shell 11, which is simple and convenient. When the faucet 100 is opened, the user applies a force to the handle 12 towards the opening position, and the protrusion 123 can 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 closing 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. Through the cooperation and guidance of the track groove 113 and the protrusion 123, the handle 12 can be accurately switched between the opening position and the closing position. In order to further ensure the assembly reliability of the handle 12 and the shell 11, the opposite sides of the accommodating cavity 111 are provided with track grooves 113, and the opposite sides of the main body 121 are provided with protrusions 123, and the two protrusions 123 and the two track grooves 113 are correspondingly and slidingly connected. Of course, in some embodiments, the positions of the track groove 113 and the protrusion 123 can also be interchanged, and the inner wall surface of the accommodating cavity 111 of the shell 11 is provided with a protrusion 123, and the outer side surface of the main body 121 of the handle 12 is provided with a track groove 113, which can also achieve the above-mentioned effect. The shape of the track groove 113 can be designed according to the specific movement track of the handle 12. In the present embodiment, the track groove 113 is an arc-shaped groove, and the handle 12 can rotate around the arc center of the track groove 113 relative to the shell 11.

[0060] Further, as shown in Figure 4 and Figure 5 , please refer to Figure 1 , Figure 4 and Figure 6In order to facilitate the assembly of the handle 12 and the valve rod 40, in one embodiment, the handle 12 is provided with a socket 124 for the valve rod 40 to be inserted, and a connecting hole 125 for the fastener 14 to be inserted, the connecting hole 125 extending along the radial direction of the socket 124 and communicating with the socket 124, and the fastener 14 is used to lock the valve rod 40 in the socket 124. In the assembly, the end of the valve rod 40 away from the valve core 30 is inserted into the socket 124 of the main body 121, and then the fastener 14 is inserted into the connecting hole 125, and the end of the fastener 14 is used to abut against the valve rod 40, which is simple and convenient. And by providing such a universal mounting position on the handle 12, without changing the structure of the valve rod 40 of the faucet 100, the valve rod 40 can be quickly assembled. In order to facilitate the assembly of the fastener 14, the fastener 14 can be a threaded fastener 14 such as a screw or a bolt, and the connecting hole 125 is a threaded hole matched with the fastener 14.

[0061] In addition, in the prior art, some faucets 100 with a delay reset function often cannot realize the switching of cold and hot water paths, and are only suitable for single water path.
