Description

Technical Field

[0001] The utility model relates to the field of faucet handles, and more specifically, to an electronic faucet handle and a faucet. Background Art

[0002] At present, the faucet handles on the market are mechanical handles, which are purely mechanical control structures. The faucet matched with the mechanical handle has a built-in ceramic valve core. The mechanical handle is connected to the ceramic valve core, and the valve core switch is operated by turning the mechanical handle, ultimately controlling the opening and closing of the faucet. However, after long-term use, the faucet handle of this mechanical structure is prone to mechanical wear and other problems at the valve core. In order to solve this problem, a structure of an electronic faucet handle has been developed. For example, the patent with application number 201810353737.X discloses a faucet with a rotating handle without mechanical contacts, which includes a solenoid valve, a rotating handle, a Hall switch, a magnet, an electronic touch switch, and a mixing valve. The opening and closing of the solenoid valve is controlled by the positional relationship between the Hall switch and the magnet. Specifically, when the Hall switch is close to the magnet, the corresponding solenoid valve can be controlled to open, thereby controlling the on / off of the water flow. By setting the electronic touch switch, when the touch switch is touched for the first time and the Hall switch is rotated to approach the magnet, the solenoid valve is opened. When the touch switch is touched again, the solenoid valve is closed. By adjusting the adjustment knob of the mixing valve, the ratio of cold water and hot water entering the mixing valve can be adjusted to achieve a comfortable water temperature. However, the electronic handle disclosed in the above structure can only control the opening and closing of the water flow, but cannot control the water temperature. The water temperature adjustment in the above structure still belongs to the pure mechanical structure control. When using it, since the mixing valve is set in the control box, it is necessary to find the position of the control box and then adjust the knob to adjust the water temperature, which is not convenient to use.

[0003] Therefore, there is an urgent need for a new type of faucet electronic handle, which can control the opening and closing of water flow and adjust the water temperature at the same time. Utility Model Content

DETAILED DESCRIPTION

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0032] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0033] like Figure 1-6 As shown, the utility model provides a faucet electronic handle 500, comprising:

[0034] Fixed seat;

[0035] A flow handle 2 is rotatably mounted on the fixed seat, and a magnet 4 is fixedly mounted on the flow handle 2;

[0036] A Hall switch 5 is fixed on the fixing seat and matched with the magnet 4, so that when the magnet 4 rotates with the flow handle 2 and approaches the Hall switch 5, the Hall switch 5 outputs a signal for controlling the opening of the first electric valve 200;

[0037] A rotary encoder, wherein the stator 18 is coaxially sleeved on the fixing seat and fixedly connected to the fixing seat;

[0038] The temperature control handle 3 is coaxially connected to the mover 19 of the rotary encoder, so that when the temperature control handle 3 is rotated, the encoder mover 19 is driven to rotate, thereby outputting a signal for controlling the opening of the second electric valve;

[0039] In the above technical solution, the flow handle 2 is coaxially rotatably arranged on the fixed seat, the flow handle 2 is provided with a magnet 4, and the fixed seat is provided with a Hall switch 5 adapted to the magnet 4, and the Hall switch 5 is located on one side of the magnet 4. When the flow handle 2 rotates, the magnet 4 is driven to rotate relative to the Hall switch 5. When the magnet 4 rotates with the flow handle 2 until the magnet 4 is close to the Hall switch 5, the Hall switch 5 outputs a signal for controlling the opening of the first electric valve 200. Specifically, when in use, the first electric valve 200 is an electric valve on the water outlet pipe 300 of the faucet 400. Control valve, when the magnet 4 moves to the first set position, the magnet 4 is close to the Hall switch 5, and the Hall switch 5 generates a first signal, which is used to control the first electric valve 200 to open the set opening, so that the first electric valve 200 can be opened to make the faucet 400 discharge water with a set flow rate. When the magnet 4 rotates with the flow handle 2 and then moves away from the Hall switch 5, the Hall switch 5 stops outputting the first signal, and the first electric valve 200 is closed at this time, and the faucet 400 does not discharge water. The cooperation between the magnet 4 and the Hall switch 5 can control the opening and closing of the faucet 400;

[0040] The rotary encoder (the following encoder) is a common encoder in the art, and its stator 18 is coaxially sleeved on the fixed seat, and the thermostat handle 3 is coaxially sleeved on the mover 19 of the encoder, so that when the thermostat handle 3 is rotated, the mover 19 of the encoder is driven to rotate synchronously, and then a signal for controlling the opening of the second electric valve is output; specifically, the second electric valve is a mixing valve 100 of the faucet 400 (a valve body for mixing cold and hot water, and the mixing valve 100 is an existing electric control valve), and when the second electric valve is at different openings, water of different temperatures can be output (the above are all prior arts and will not be repeated here). When in use, after the thermostat handle 3 is rotated to a set angle, the mover 19 of the encoder rotates synchronously and generates a second signal, and the second signal controls the second electric valve to open a corresponding opening (the opening corresponds to the rotation angle) so that the faucet 400 outputs water of the set temperature, each rotation angle corresponds to an opening, and each opening corresponds to a water temperature, so as to achieve stepless adjustment of the water temperature;

[0041] The beneficial effect obtained by adopting this technical solution is that by setting a fixed seat, a flow handle 2, a Hall switch 5, a magnet 4, a temperature control handle 3, and a rotary encoder, a faucet electronic handle 500 is provided, which can not only realize the electronic adjustment of the faucet 400 switch but also realize stepless adjustment of the water temperature.

At the second opening, the faucet 400 is closed. When in use, people can set the position of the Hall switch 5 according to their needs. When the flow handle 2 is in the initial position, the magnet 4 is close to the second sub-Hall switch. At this time, the first electric valve 200 is closed. The flow handle 2 is turned 30 degrees or 45 degrees to the left, and the magnet 4 is close to the first sub-Hall switch. At this time, the faucet 400 outputs the first water flow rate. The flow handle 2 is turned 30 degrees or 45 degrees to the right, and the magnet 4 is close to the third sub-Hall switch. At this time, the faucet 400 outputs the second water flow rate.
