In related technologies, the display screen can be powered by batteries. However, if the display screen is in a display state for a long time, it is easy to waste resources. Utility Model Content

[0004] The purpose of this utility model is to provide a handwheel mechanism and a faucet, in which the display state and the off state of the display screen can be linked by the rotation of the handwheel body, so that the display screen can be in the off state when the faucet is not in use, thus saving resources.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] One aspect provides a handwheel mechanism, which includes a handwheel body, a display screen, a first sensor, a second sensor, and a valve assembly.

[0007] The valve assembly includes a valve core cover and a valve stem, the valve stem being connected to the handwheel body, and the handwheel body being capable of driving the valve stem to rotate;

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] like Figures 1 to 6As shown, this embodiment provides a faucet, which includes a faucet body 9 and a handwheel mechanism. The handwheel mechanism includes a handwheel body 1, a valve assembly 2, a display screen 3, a first sensor (not shown in the figure), and a second sensor 4. The valve assembly 2 includes a valve core cover 201, a valve stem 202, and a valve core 203. The valve core 203 is disposed inside the faucet body 9, the valve core cover 201 is fixed to the faucet body 9, and the valve stem 202 is rotatably disposed on the valve core cover 201. One end of the valve stem 202 is connected to the valve core 203 so that the valve stem 202 can pass through. The rotation of the valve stem 202 drives the valve core 203 to rotate, controlling the water flow. The other end of the valve stem 202 is connected to the handwheel body 1, which rotates on the faucet body 9, so that the valve stem 202 can be rotated through the handwheel body 1. The display screen 3 is fixed on the handwheel body 1. The first sensor is set on the display screen 3 or the handwheel body 1, and the second sensor 4 is set on the valve core cover 201, so that when the handwheel body 1 rotates relative to the valve core cover 201, the relative position of the first sensor and the second sensor 4 can change, so as to turn the display screen 3 on or off.

[0038] The above structure allows the first and second sensors to face each other when the faucet is not in use, and the display screen 3 is simultaneously turned off. When the handwheel body 1 is turned, the operator uses the faucet, and the first sensor rotates with the handwheel body 1, causing a positional shift between the first and second sensors 4, resulting in misalignment. This turns the display screen 3 on, thus linking the on / off state of the display screen 3 to the rotation of the handwheel body 1. This allows the display screen 3 to be off when the faucet is not in use, saving resources, and to be on when the faucet is in use, making it easy for the operator to observe.

[0039] like Figure 2 As shown, in some embodiments, a temperature monitoring element 10 can be installed inside the faucet body 9 to monitor the water temperature inside the faucet body 9. The temperature monitoring element 10 is connected to the display screen 3, so that the water temperature monitored by the temperature monitoring element 10 is displayed on the display screen 3. Of course, it is understood that the faucet may also include other monitoring elements, such as water quality monitoring elements, so that more information can be displayed on the display screen 3.

[0040] like Figure 4 and Figure 6As shown, in some embodiments, the handwheel body 1 has an annular structure, the valve core cover 201 is located at one end of the handwheel body 1, and the valve stem 202 extends into the handwheel body 1 and is connected to the handwheel body 1. The display screen 3 is fixed to the end of the handwheel body 1 away from the valve core cover 201, so that the display screen 3 can rotate with the handwheel body 1. It should be noted that the handwheel body 1 and the display screen 3 can be connected by detachable methods such as snap-fit, plug-in, or screw-fit, which facilitates disassembly and maintenance. In the current embodiment, the first sensor is disposed on the display screen 3, and the second sensor 4 can be disposed on the valve core cover 201, so that when the handwheel body 1 rotates, the positions of the first sensor and the second sensor 4 can change. For example, the second sensor 4 is a magnet, and the first sensor is a Hall element, which is integrated with the display screen 3; or the first sensor can be disposed on the handwheel body 1 and signal-connected to the display screen 3.

[0041] It is understandable that the display screen 3 can also be set on the side wall of the handwheel body 1, and it can also rotate with the handwheel body 1.

[0042] In the current embodiment, in order to ensure the accuracy of sensing between the first sensor and the second sensor 4 and to minimize the distance between the first sensor and the second sensor 4, a first fixing seat 5 extending towards the display screen 3 is provided on the valve core cover 201, and the second sensor 4 is fixed on the first fixing seat 5.

[0043] like Figure 2 and Figure 5 As shown, in the current embodiment, to facilitate the connection of the valve stem 202, the valve stem 202 is connected to the inner wall of the handwheel body 1. Specifically, a connecting seat 7 is provided on the inner wall of the handwheel body 1. Exemplarily, the connecting seat 7 is integrally formed with the handwheel body 1. The connecting seat 7 is provided with a fixing hole 701, and the valve stem 202 is inserted into the fixing hole 701 to fix the connecting seat 7 and the valve stem 202. More specifically, to ensure a stable connection between the connecting seat 7 and the valve stem 202, a connecting hole 205 is provided at the top of the valve stem 202. A locking member 8 is provided on the connecting seat 7. The connecting seat 7 and the valve stem 202 can be locked and fixed in the connecting hole 205 by the locking member 8. Exemplarily, the locking member 8 is a bolt or screw, and the connecting hole 205 is a screw hole, so that the connecting seat 7 and the valve stem 202 are fixed by bolting or screwing into the screw hole. By securing the connecting seat 7 to the valve stem 202 with the locking member 8, the possibility of the handwheel body 1 disengaging along the axial direction of the valve stem 202 can be reduced. Furthermore, the outer wall of the valve stem 202 is provided with a plurality of first protrusions 204 along its circumference, and the inner wall of the fixing hole 701 is provided with a plurality of second protrusions 702 along its axial direction. The first protrusions 204 are embedded between two adjacent second protrusions 702, thereby preventing slippage between the handwheel body 1 and the valve stem 202 when they rotate, thus improving stability.

[0044] Example 2:

[0045] like Figure 7 and Figure 8 As shown, in the current embodiment, the handwheel body 1 is also a ring structure, the valve core cover 201 is located at one end of the handwheel body 1, and the display screen 3 is located at the other end of the handwheel body 1. Unlike the first embodiment, the valve core cover 201 is fixedly connected to the display screen 3, while the valve rod 202 extends into the handwheel body 1 and is connected to the handwheel body 1. At this time, the display screen 3 is fixed on the valve core cover 201. The first sensing element is set on the display screen 3 or the valve core cover 201. Thus, when the handwheel body 1 drives the valve rod 202 to rotate, neither the valve core cover 201 nor the display screen 3 rotates with the handwheel body 1. The fact that the display screen 3 does not rotate makes it convenient for the user to observe the display screen 3.

[0046] In the current embodiment, the first sensor is disposed on the display screen 3, and the second sensor 4 can be disposed on the handwheel body 1, so that when the handwheel body 1 rotates, the positions of the first sensor and the second sensor 4 can change. Exemplarily, the second sensor 4 is also a magnet, and the first sensor is also a Hall element, and is integrated with the display screen 3; or the first sensor is disposed on the valve core cover 201 and is signal-connected to the display screen 3.

[0047] To facilitate the connection between the valve core cover 201 and the display screen 3, a second fixing seat 6 extending towards the display screen 3 is provided on the valve core cover 201, and the display screen 3 is fixedly connected to the second fixing seat 6.

[0048] In the current embodiment, to facilitate the connection of the valve stem 202, the valve stem 202 is connected to the inner wall of the handwheel body 1. Specifically, the inner wall of the handwheel body 1 is also provided with a connecting seat 7, and the connection method between the connecting seat 7 and the valve stem 202 is the same as that in Embodiment 1, and will not be described again.

[0049] like Figure 8 As shown, in the current embodiment, the second sensor 4 is fixed on the side of the connecting seat 7 facing the display screen 3, thereby minimizing the distance between the first sensor and the second sensor 4 and improving the accuracy of sensing by the first sensor and the second sensor 4.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
