Abstract
Description
Technical Field
[0001] This utility model relates to the field of controller technology, and in particular to a rotary controller. Background Technology
[0002] Household appliances typically use controllers to adjust their functions. For example, appliances such as induction cookers, water heaters, and refrigerators usually have control knobs to adjust parameters such as time, speed, and temperature.
[0003] Traditional rotary controllers use a lever to activate microswitches to adjust parameters. Specifically, a rotary controller requires a lever and multiple microswitches. By rotating the lever, different microswitches are activated, thereby adjusting the parameters. However, these microswitches can only be adjusted to specific parameters at the contact points and cannot adjust arbitrary parameters. Furthermore, long-term use may lead to problems such as poor contact. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] like Figure 1-5 As shown, this embodiment provides a rotary controller, including a fixed base 1, a control board 2, a display panel 3, and a rotating ring 4. The control board 2 is fixed on the top of the fixed base 1, and a Hall element 5 is fixed on the control board 2. The display panel 3 is fixed above the control board 2. The rotating ring 4 is rotatably sleeved around the fixed base 1, the control board 2, and the display panel 3. A magnetic ring 6 is fixed on the inner side of the rotating ring 4.
[0026] Specifically, the Hall element 5 can be fixed at the bottom edge of the control board 2, and the magnetic ring 6 is sleeved on the outside of the control board 2 and rotates relative to the Hall element 5. The positions of the fixed base 1, the control board 2, and the display panel 3 are relatively fixed. The rotating ring 4 can rotate around the outer periphery of the fixed base 1, the control board 2, and the display panel 3. The magnetic ring 6 inside the rotating ring 4 rotates with the rotating ring 4, that is, the magnetic ring 6 rotates relative to the Hall element 5, thereby causing the Hall element 5 to generate a sensing signal. Based on this sensing signal, the functional parameters of the electrical appliance can be controlled. Because the strength of the sensing signal is related to the degree of rotation of the magnetic ring 6, the functional parameters of the electrical appliance can be arbitrarily adjusted by the degree of rotation of the magnetic ring 6. At the same time, this sensing is non-contact sensing, which has a longer service life than contact sensing.
[0027] A support frame 7 is fixed on the control board 2, and the display panel 3 is fixed above the support frame 7. The support frame 7 supports the display panel 3 and the control board 2, making the connection more stable.
[0028] As a preferred method, refer to Figure 2 The control board 2 is equipped with LED beads 8, and a light shield 9 is located above the control board 2. The light shield 9 is fixed to the support frame 7, and a light-transmitting hole 10 is opened on the light shield 9, which is located directly above the LED beads 8. The control board 2 controls the LED beads 8 to work. The LED beads 8 shine upwards onto the light shield 9, and the light is emitted from the light-transmitting hole 10. The shape of the light-transmitting hole 10 is the parameter to be displayed. The light shines on the display panel 3 and finally passes through the display panel 3.
[0029] As another preferred method, refer to Figure 3 A digital display screen 11 is provided above the control panel 2. The digital display screen 11 is fixed on the support frame 7. The function parameters are directly displayed on the digital display screen 11. The display on the digital display screen 11 can be seen through the display panel 3.
[0030] refer to Figure 4 and Figure 5 A gear structure 12 is provided on the fixed base 1. A rotating plate 13 extends inward from the bottom of the rotating ring 4. At least one actuating spring 14 is fixed on the rotating plate 13. The actuating spring 14 includes a serrated structure 1401, which meshes with the gear structure 12. When the rotating ring 4 rotates, the actuating spring 14 rotates accordingly. The serrated structure 1401 continuously meshes with each tooth of the gear structure 12, increasing the rotational resistance. The rotating ring 4 will not rotate on its own when not under force, ensuring the reliability of rotation.
[0031] The actuating spring 14 includes two spring rods 1402, which are respectively located at both ends of the sawtooth structure 1401. The outer ends of the spring rods 1402 are fixed to the rotating plate 13, and the rotating plate 13 has through holes 15 for the sawtooth structure 1401 to pass through. By increasing the elasticity of the actuating spring 14 through the spring rods 1402, the sawtooth structure 1401 can smoothly enter and exit each tooth of the gear structure 12. By positioning the sawtooth structure 1401 between the two spring rods 1402, the force on the sawtooth structure 1401 is ensured to be uniform, so as to smoothly realize clockwise and counterclockwise rotation.
[0032] A rotating hole 16 is provided at the center of the rotating plate 13. A limiting ring 17 is provided on the fixed base 1. The limiting ring 17 is fitted into the rotating hole 16. A limiting block 18 extends outward from the top of the limiting ring 17, and the bottom surface of the limiting block 18 contacts the edge of the rotating plate 13. When the rotating ring 4 rotates, the rotating plate 13 on it will rotate along the limiting ring 17. At the same time, the edge of the rotating plate 13 will rotate along the bottom surface of the limiting block 18. The limiting ring 17 and the limiting block 18 can restrict the position of the rotating plate 13 and increase the stability of the rotating ring 4 and the rotating plate 13 during rotation.
[0033] The fixed base 1 is provided with a limiting protrusion 19 and / or a limiting boss 20, and the rotating plate 13 is provided with a guide groove 21 for the limiting protrusion 19 and / or the limiting boss 20 to be inserted. The limiting protrusion 19 and / or the limiting boss 20 provide a guiding function for the rotation of the rotating plate 13, further increasing the stability of the rotating plate 13 when it rotates.
[0034] refer to Figure 2 An embedded base 22 is fixed under the fixed base 1. A first connecting hole 23 is opened at the center of the embedded base 22, and a second connecting hole 24 is opened at the center of the fixed base 1. The second connecting hole 24 is connected to the first connecting hole 23. The embedded base 22 is used to install the rotary controller on the electrical appliance. Wires and other components are passed through both the second connecting hole 24 and the first connecting hole 23 to achieve an electrical connection between the rotary controller and the electrical appliance.
[0035] The rotating ring 4 includes an outer ring 401 and an inner ring 402. The top of the outer ring 401 is provided with a first pressing ring 403 extending inward. The inner ring 402 is sleeved and fixed inside the outer ring 401. The top of the inner ring 402 is provided with a second pressing ring 404 extending inward. The outer periphery of the display panel 3 is located between the first pressing ring 403 and the second pressing ring 404.
[0036] The edge of the display panel 3 is defined between the first retaining ring 403 and the second retaining ring 404, which minimizes the area of the display panel 3 that is obstructed, resulting in a better display effect. At the same time, a limiting groove is formed between the first retaining ring 403 and the second retaining ring 404, which guides the rotation of the top of the rotating ring 4. The uniformity of light can also be increased by setting a diffuse reflector 25 below the display panel 3. The diffuse reflector 25 can be fixed on the support frame 7.
[0037] This invention achieves rotation of the magnetic ring 6 relative to the Hall element 5 by fixing a magnetic ring 6 on the rotating ring 4 and a Hall element 5 on the control plate 2, thereby generating a sensing signal from the Hall element 5. The functional parameters of the electrical appliance can be arbitrarily adjusted by the degree of rotation of the magnetic ring 6. At the same time, this sensing is non-contact sensing, which has a longer service life compared to contact sensing. By setting a gear structure 12 on the fixed base 1 and fixing a toggle spring 14 on the rotating plate 13, the meshing of the toggle spring 14 and the gear structure 12 is achieved, increasing the rotational resistance of the rotating ring 4 and ensuring the reliability of rotation.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
