The second PCB 102 is provided with a first connection pad group, and the first PCB 101 is provided with a second connection pad group corresponding to the first connection pad group. The second PCB 102 is soldered to the first PCB 101 by soldering the first connection pad set and the second connection pad set. It is apparent that the first connection pad group and the second connection pad group have an effect of transmitting an electric signal in addition to the effect of the fixed connection, so that the sensing unit U1 disposed on the second PCB board 102 is electrically connected with the first control unit disposed on the first PCB board 101.

In this luminous knob structure, because sensing unit U1 is set up at second PCB board 102, when sensing unit U1 need carry out the maintenance, directly with second PCB board 102 change can. And the later maintenance of the luminous knob structure is convenient. And because the second PCB 102 can be produced in a modularized manner, the assembly efficiency of the whole luminous knob structure is improved, and the production is convenient.

In order to explain the rotary light emitting function of the book light emitting knob structure, the circuit structures on the first PCB board 101 and the second PCB board 102 are explained below. In some further embodiments, the circuit structure includes: the LED lamp comprises a power supply interface CN1, a first resistor R1, an induction unit U1, a first LED lamp group and a first control unit. Wherein the first control unit includes: the second resistor R2, the third resistor R3 and the first triode Q1. The first LED light group includes: a first light emitting diode LED1, a second light emitting diode LED2, a third light emitting diode LED3 and a fourth light emitting diode LED4. The power supply interface CN1, the first resistor R1, the first LED lamp set, and the first control unit are disposed on the first PCB 101. The sensing unit U1 is disposed on the second PCB 102.

The positive electrode of the power supply interface CN1 is connected with one end of the first resistor R1, the anode of the first light emitting diode LED1, the anode of the second light emitting diode LED2, the anode of the third light emitting diode LED3 and the anode of the fourth light emitting diode LED4 respectively. The other end of the first resistor R1 is connected with the input end of the sensing unit U1, the output end of the sensing unit U1 is connected with one end of a third resistor R3, and the other end of the third resistor R3 is connected with the base electrode of the first triode Q1. The collector of the first triode Q1 is connected with one end of a second resistor R2, and the other end of the second resistor R2 is respectively connected with the cathode of the first diode, the cathode of the second diode, the cathode of the third diode and the cathode of the fourth diode. The grounding end of the sensing unit U1 and the emitter of the first triode Q1 are respectively connected with the negative electrode of the power supply interface CN 1. In actual operation, the power supply interface CN1 may be connected to a power source, and in this specific embodiment, the power source is a button cell. The base 200 is provided with a location for mounting a button cell mounted in the receiving cavity 210 of the base 200. The button cell provides electric energy for the circuit structure.

Because the trigger is arranged on the rotary shell, when the rotary shell rotates, the trigger is driven by the rotary shell and moves to the position of the sensing unit U1, so that the triggering of the sensing unit U1 is realized. When the sensing unit U1 is triggered, the output terminal of the sensing unit U1 outputs a high level, and the high level acts on the first triode Q1 through the third resistor R3, so that the first triode Q1 is turned on. Since the first transistor Q1 is turned on, the first, second, third, and fourth light emitting diodes LED1, LED2, LED3, and LED4 are turned on. By this, the function of the trigger triggering sensing unit U1 is realized, and the first control unit lights the first LED lamp group.

In some further embodiments, the sensing unit U1 is a magnetically controlled switching unit. The trigger is a permanent magnet.

In order to achieve more uniform light emitted by the first LED lamp set, in some further embodiments, the light-emitting knob structure further includes a diffusion plate (not shown) disposed in the accommodating cavity 210 of the base 200 and above the first PCB 101, where the diffusion plate is used to diffuse the light emitted by the first LED lamp set. In the receiving cavity 210 of the base 200, the first PCB 101 is fixed in the receiving cavity 210 by screws. The diffusion plate is disposed above the first PCB 101. The diffusion plate may cover the first PCB 101, and when the first LED lamp set emits light, the diffusion plate may diffuse the emitted light. The first LED lamp group is enabled to emit light more gently and uniformly, and user identification is facilitated.

In order to make the trigger the sensing unit U1 better, in some further embodiments, a window is provided on the diffusion plate. The window is located right above the sensing unit U1. By doing so, the influence of the diffusion plate on the response of the sensing unit U1 to the trigger of the trigger is reduced.

In order to increase the functionality of the present luminous knob structure, in some further specific embodiments, the first PCB board 101 is further provided with a second LED lamp set and a second control unit, where the second LED lamp set and the sensing unit U1 are connected to the second control unit, respectively, and the second control unit is configured to light the second LED lamp set when the sensing unit U1 is not triggered, and the second control unit is configured to extinguish the second LED lamp set when the sensing unit U1 is triggered.

The second LED lamp group includes: a fifth light emitting diode LED5, a sixth light emitting diode LED6, a seventh light emitting diode LED7 and an eighth light emitting diode LED8. The second control unit includes: a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a second transistor Q2, and a third transistor Q3.

One end of the anode of the fifth light emitting diode LED5, the anode of the sixth light emitting diode LED6, the anode of the seventh light emitting diode LED7, the anode of the eighth light emitting diode LED8 and one end of the fifth resistor R5 are respectively connected with the positive electrode of the power supply interface CN 1.

The base of the third triode Q3 is connected with one end of a fourth resistor R4, and the other end of the fourth resistor R4 is connected with the output end of the sensing unit U1.

The emitter of the third triode Q3 and the emitter of the second triode Q2 are respectively connected with the cathode of the power supply interface CN1, the collector of the second triode Q2 is connected with one end of a sixth resistor R6, and the other end of the sixth resistor R6 is respectively connected with the cathode of a fifth light emitting diode LED5, the cathode of a sixth light emitting diode LED6, the cathode of a seventh light emitting diode LED7 and the cathode of an eighth light emitting diode LED8.

In this embodiment, the present light-emitting knob structure has two light-emitting states, and the first state is indicated by the second LED lamp group, and the second state is indicated by the first LED lamp group. In the first state, the knob housing 100 is in an initial state. At this time, the trigger does not trigger the sensing unit U1. At this time, the output end of the sensing unit U1 outputs a low level, and under the action of the low level, the first triode Q1 is turned off, and at this time, the first LED lamp set is not energized and is not turned on. Namely the first light emitting diode LED1, the second light emitting diode LED2, the third light emitting diode LED3 and the fourth light emitting diode LED4 do not emit light. The low level acts in the third transistor Q3 through the fourth resistor R4, so that the third transistor Q3 is turned off. Since the third transistor Q3 is turned off, the potential of the collector of the third transistor Q3 is pulled high. At this time, the potential of the collector of the third transistor Q3 forms a high level, which acts in the base of the second transistor Q2, so that the second transistor Q2 is turned on. Since the second transistor Q2 is turned on, the second LED lamp group is lighted. That is, the fifth light emitting diode LED5, the sixth light emitting diode LED6, the seventh light emitting diode LED7, and the eighth light emitting diode LED8 emit light. The first state is indicated by the illumination of the second LED lamp set.

When the knob housing 100 is rotated, the trigger is driven by the rotating housing and moves to the sensing unit U1, thereby triggering the sensing unit U1. When the sensing unit U1 is triggered, the output terminal of the sensing unit U1 outputs a high level, and the high level acts on the first triode Q1 through the third resistor R3, so that the first triode Q1 is turned on. Since the first transistor Q1 is turned on, the first, second, third, and fourth light emitting diodes LED1, LED2, LED3, and LED4 are turned on. Since the high level output from the output terminal of the sensing unit U1 acts on the third transistor Q3 through the fourth resistor R4, the third transistor Q3 is turned on. At this time, the collector of the third transistor Q3 is pulled low to form a low level. The low level acts in the second transistor Q2 such that the second transistor Q2 is turned off. So that the second LED lamp set is not energized and is not illuminated. Namely, the fifth, sixth, seventh and eighth light emitting diodes LED5, LED6, LED7 and LED8 do not emit light. The second state is indicated by the illumination of the first LED lamp set.

In order to facilitate better identification of the first state and the second state, in some further embodiments, the light emitted by the first LED lamp set is red light. And the light emitted by the second LED lamp group is blue light.

In order to facilitate the installation of the base 200 on the barbecue oven, the luminous knob structure further comprises a cushion (not shown) which is arranged at the bottom of the base 200. Wherein, the cushion is silica gel material component.

In some further embodiments, the diffuser plate is a PC material member.

While the preferred embodiments of the present utility model have been illustrated and described, the utility model is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the utility model, and these are intended to be included within the scope of the present utility model as defined in the appended claims.
