[0025] The serial numbers assigned to components in this document, such as "first" and "second," are merely configured to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0026] In one embodiment, this application provides a data transmission circuit, such as... Figure 1 As shown, Figure 1 This is a schematic block diagram of a data transmission circuit according to an embodiment of this application. The data transmission circuit is applied to an atomizing device including a display component and a control component. The display component is configured to rotate relative to the control component. The data transmission circuit includes: a detection link, including a transmitting unit disposed on the display component and a receiving unit disposed on the control component; the transmitting unit is used to transmit an alignment signal during rotation, and the receiving unit is used to generate a trigger command when the alignment signal is received; a communication link, including a data transmitting end disposed on the control component and a data receiving end disposed on the display component; the data transmitting end is connected to the receiving unit and is used to transmit display data in response to the trigger command; when the transmitting unit and the receiving unit are spatially coupled, the data transmitting end and the data receiving end are in a communicable aligned state.

[0027] This embodiment provides a data transmission circuit for an atomizing device. The atomizing device includes a control component and a display component. The control component can be fixedly encapsulated inside the housing of the atomizing device and integrates conventional modules such as a microcontroller unit (MCU), a power supply, and an atomization drive circuit to realize the atomization function. The display component is a rotating module equipped with a display screen, which can rotate relative to the control component around a preset rotation axis within a preset angle range. For example, the display component can be integrated into the rotatable mouthpiece of the atomizing device. The user can rotate and adjust the mouthpiece angle according to their grip habits, and the display component rotates synchronously with the mouthpiece.

[0028] In the data transmission circuit provided in this application embodiment, the display component and the control component preferably communicate using infrared light (IR). This communication method has the characteristics of strong anti-electromagnetic interference capability, which can improve the data transmission stability between the display component and the control component.

[0029] The data transmission circuit in this embodiment includes a detection link and a communication link: the detection link includes a transmitting unit and a receiving unit, wherein the transmitting unit may include an infrared emitting tube (infrared light-emitting diode), which is fixedly soldered to the display component, and its emitting surface can be aligned with different parts as the display component rotates, for continuously emitting infrared light as an alignment signal at a preset frequency during the rotation of the display component; the receiving unit may include an infrared receiving tube matched with the infrared emitting tube, which is fixedly soldered to the side of the control component facing the display component, and the signal output terminal of the receiving unit can be electrically connected to the MCU, for outputting a high-level trigger command to the MCU when receiving an infrared alignment signal with an intensity reaching a preset threshold.

[0030] The communication link includes a data transmitter and a data receiver. The data transmitter may include an infrared communication transmitter module (infrared emitting tube) and a data processing module (MCU), which are fixedly soldered to the control component. The communication transmitter module can be electrically connected to the serial port output of the MCU's Universal Asynchronous Receiver / Transmitter (UART), enabling the communication transmitter module to transmit modulated display data in response to trigger commands received by the MCU. The display data can be the current atomizing device usage status data generated by the MCU, including but not limited to remaining battery power, cumulative number of suction ports, current heating power level, and remaining atomizing liquid. The data receiver can be an infrared communication receiver module (infrared receiving tube) matched with the infrared communication transmitter module, which is fixedly soldered to the display component. Its photosensitive surface can be aligned with different parts as the display component rotates, and it is used to receive display data during the rotation of the display component. The data receiver is electrically connected to the display element of the display component to receive the display data and transmit it to the display element. The display element can convert the display data into display content on the screen.

[0031] In this embodiment, the transmitting unit and the data receiving end are fixed to the display component, and they can be arranged on the same rotation reference plane of the display component with fixed relative positions. The receiving unit and the data transmitting end are fixed to the control component, and they can be arranged on the same fixed reference plane of the display component with fixed relative positions. The rotation reference plane and the fixed reference plane can be parallel during the rotation of the display component. When the display component rotates to the point where the transmitting unit and the receiving unit are spatially aligned (e.g., the rotation reference plane is parallel to the fixed reference plane), the infrared light emitted by the transmitting unit is incident on the photosensitive surface of the receiving unit without obstruction, and the two achieve spatial coupling. At this time, the data transmitting end and the data receiving end are exactly in a spatially aligned state, the signal transmission path is shortest and unobstructed, the signal strength is highest, and it is in the optimal state for communication.

[0032] The data transmission circuit of this application embodiment can operate as follows: When the user rotates the display component, the display component drives the transmitting unit and the data receiving end to rotate synchronously around a preset rotation axis. The transmitting unit continuously emits infrared alignment signals. When the display component rotates to the point where the transmitting unit is directly opposite the receiving unit, the receiving unit receives an infrared alignment signal of sufficient strength, generates a trigger command, and sends it to the MCU. After receiving the trigger command, the MCU calls up the latest display data currently stored, transmits it to the data transmitting end for modulation, and then transmits it externally. At this time, the data transmitting end and the data receiving end are directly opposite each other, and the data receiving end can stably receive the complete display data, which is then transmitted to the display element to refresh the display content.

[0033] In one optional implementation of this embodiment, the display component can be provided with multiple identical transmitting units at intervals along the rotation direction. Each transmitting unit is configured with a data receiving end, so that the display component can trigger a data transmission once every time it rotates a preset angle. This adapts to the user's usage habits, and the display data can be refreshed quickly no matter which common angle the user adjusts the display of the display component to, without having to wait for it to rotate to a single alignment position.

[0034] In this embodiment, the data transmission circuit includes a detection link and a communication link. The detection link includes a transmitting unit and a receiving unit, and the communication link includes a data transmitting end and a data receiving end. By setting up a pair of transmitting and receiving units that can synchronously transmit and receive data with the data transmitting end and the data receiving end, a trigger command is generated when the receiving unit receives the alignment signal sent by the transmitting unit. This determines that the signal transmission area of ​​the communication circuit overlaps with the signal reception area of ​​the data receiving circuit, and that the data transmitting end and the data receiving end are in an optimal data interaction position. The data receiving end can receive display data with a stronger signal strength sent by the data transmitting end. Therefore, at this time, the data transmitting end responds to the trigger command and sends display data to the data receiving end for display component display, which can ensure the stability of data transmission between the display component and the control component and guarantee the data transmission effect.

[0035] In some embodiments, such as Figure 2 As shown, Figure 2 This is a schematic diagram of the circuit structure of the data transmitter, which displays the data as an infrared light signal. The data transmitter includes a data processing module 11 and a first infrared emitting module 12. The data processing module 11 is connected to the receiving unit and the first infrared emitting module 12, and is used to generate initial data to be displayed by the display component in response to a trigger command, and control the first infrared emitting module 12 to convert the initial data into an infrared light signal and then emit it.

[0036] The data processing module 11 can be an MCU, used to generate initial data to be displayed by the display component in response to a trigger command. This initial data can be sent based on the UART communication protocol and processed by the first infrared transmitting module 12 of the data transmitting end. The first infrared transmitting module 12 can receive the initial data to be displayed by the display component through the IR_DAT terminal shown in the figure, and convert the initial data to be displayed by the display component into an infrared light signal and then transmit it for the data receiving end of the display component to receive.

[0037] In some embodiments, such as Figure 2As shown, the first infrared emitting module 12 includes: a first switch Q4 and a first infrared emitting tube D6; the first end of the first switch Q4 is connected to the data processing module 11, the second end of the first switch Q4 is grounded, the third end of the first switch Q4 is connected to the cathode of the first infrared emitting tube D6, and the anode of the first infrared emitting tube D6 is used to connect to the first power supply B1; the first switch Q4 is used to make the first infrared emitting tube D6 light up or turn off under the control of initial data, so as to emit infrared light signals.

[0038] The main functional components of the first infrared emitting module 12 include a first switch Q4 and a first infrared emitting diode D6 (infrared light-emitting diode). Specifically, the first switch Q4 can be a transistor, with its first terminal (base) being the IR_DAT terminal, connected to the data processing module 11 to receive initial data to be displayed from the display component. This terminal can be connected in series with a resistor (not shown in the figure) to ensure the transistor operates in the saturation region. Its second terminal (emitter) is grounded (chassis ground, GND). Another resistor (not shown in the figure) can be connected in parallel between the base and emitter to ensure the stability of the transistor in the off-state (i.e., the third switch Q1 is off). Its third terminal (collector) is connected to the cathode of the first infrared emitting diode D6, and the anode of the first infrared emitting diode D6 is connected to the first power supply B1. A third resistor R27 can also be connected in series between the first power supply B1 and the third terminal of the first switch Q4 to ensure that the first infrared emitting diode D6 operates within the normal voltage drop range. For example, the resistance value of the third resistor R27 can be 220Ω. Ω; When the first switch Q4 is turned on, the circuit consisting of the first power supply B1 and the first infrared emitting diode D6 is turned on, and current flows through the first infrared emitting diode D6, causing the first infrared emitting diode D6 to emit light. When the first switch Q4 is turned off, the circuit consisting of the first power supply B1 and the first infrared emitting diode D6 is turned off, and the first infrared emitting diode D6 is turned off. Therefore, by controlling the first switch Q4 to turn on or off through initial data, the first infrared emitting diode D6 can be controlled to emit light or turn off, thereby converting the initial data into an infrared light signal to be sent to the data receiving end of the display component.

[0039] In some embodiments, such as Figure 3 As shown, Figure 3 The diagram shows the circuit structure of the data receiving end, which includes a first infrared receiving module 21 and an interference processing module 22. The first infrared receiving module 21 is electrically connected to the display component through the interference processing module 22. It is used to receive infrared light signals and convert the received infrared light signals into electrical signals before transmitting them to the interference processing module 22. The interference processing module 22 is used to drive the display component to display based on the electrical signals when the voltage of the electrical signals is within the target voltage range corresponding to the infrared light signals converted from the initial data.

[0040] The data receiving end can be divided into a first infrared receiving module 21 and an interference processing module 22. The core of the first infrared receiving module 21 can be a photosensitive element (phototransistor or photodiode), which conducts after receiving light (infrared light), thereby receiving infrared light signals and converting them into electrical signals. The first infrared receiving module 21 is electrically connected to the display component through the interference processing module 22. That is, the interference processing module 22 is simultaneously connected to the first infrared receiving module 21 and the display element PB-IR of the display component. By receiving the electrical signal generated by the first infrared receiving module 21, the interference processing module 22 can drive the display element PB-IR of the display component to display when the voltage of the electrical signal is within a preset target voltage range, thereby generating new display content on the display screen of the display component. Through the interference processing module 22, the generation of display content based on the electrical signal within the target voltage range can filter out possible infrared interference signals and ensure the authenticity of the transmitted display data.

[0041] In some embodiments, such as Figure 3 As shown, the interference processing module 22 includes: a comparison submodule 221 and a second switch Q2; the comparison submodule 221 is connected to the first terminals of the first infrared receiving module 21 and the second switch Q2 respectively, and is used to output a target level signal to the second switch Q2 when the voltage of the electrical signal is within the target voltage range; the second terminal of the second switch Q2 is connected to the second power supply B2, and the third terminal of the second switch Q2 is electrically connected to the display component, and is used to connect the second power supply B2 and the display component under the control of the target level signal, so that the output signal of the second power supply B2 drives the display component to display.

[0042] The interference processing module 22 can be specifically divided into a comparison submodule 221 and a second switch Q2. The second switch Q2 can be a transistor, with its first terminal (base) connected to the comparison submodule 221, its second terminal (emitter) connected to the second power supply B2, and its third terminal (collector) electrically connected to the display component (display element PB-IR). It is also grounded through a fourth resistor R15. For example, the resistance of the fourth resistor R15 can be 10 kΩ. Based on the electrical signal within the target voltage range obtained by the first infrared receiving module 21, the comparison submodule 221 can output a target level signal to the second switch Q2. This signal is input through the first terminal of the second switch Q2 to control the on / off state of the second switch Q2. When the second switch Q2 is turned on, the second power supply B2 is connected to the display element PB-IR of the display component. The display element PB-IR receives the output signal of the second power supply B2, causing the display screen to output display content. When the second switch Q2 is turned off, the second power supply B2 is disconnected from the display component, and the display screen of the display component turns off. By controlling the turning on and off of the second switch Q2 based on the target level signal, the connection and disconnection between the second power supply B2 and the display element PB-IR of the display component can be controlled, further controlling the lighting and turning off of the display screen of the display component, thereby driving the display screen of the display component to output display content according to the display data.

[0043] In some embodiments, the lower limit of the target voltage range is the interference voltage; such as Figure 3 As shown, the comparison submodule 221 includes: a third switch Q1 and a voltage divider circuit 222; the first terminal of the third switch Q1 is connected to the first infrared receiving module 21, the second terminal of the third switch Q1 is connected to the first terminal of the second switch Q2, the third terminal of the third switch Q1 is grounded, and is connected to the third power supply B3 through the voltage divider circuit 222. The interference voltage is the voltage divider circuit 222 divides the output voltage of the third power supply B3; the third switch Q1 is used to ground the first terminal of the second switch Q2 when the voltage of the electrical signal is greater than the interference voltage, so as to receive the target level signal.

[0044] The lower limit of the target voltage range is the interference voltage. The interference processing module 22 can filter electrical signals below the interference voltage to remove infrared interference. It can be understood that when the data transmitter transmits display data to the data receiver based on the alignment signal, the data transmitter and the data receiver are aligned and their physical distance is closest during the rotation of the display component. At this time, the display data is sent as an infrared light signal. Theoretically, the radiation energy of the infrared interference will only be lower than the energy of the infrared light signal transmitting the data. Therefore, the lower energy infrared interference and the higher energy display data can be distinguished by the interference voltage.

[0045] The comparison submodule 221 may specifically include a third switch Q1 and a voltage divider circuit 222. The third switch Q1 may specifically be a transistor, with its first terminal (base) connected to the first infrared receiving module 21 to receive the electrical signal generated by the first infrared receiving module 21. The third terminal (emitter) of the third switch Q1 is grounded and connected to the third power supply B3 through the voltage divider circuit 222. The specific value of the interference voltage can be determined by the voltage divider circuit 222 dividing the output voltage of the third power supply B3.

[0046] The second terminal (collector) of the third switch Q1 is connected to the first terminal of the second switch Q2 through the fifth resistor R14. The first terminal of the second switch Q2, after passing through the fifth resistor R14, is also connected to the second power supply B2 through the eighth resistor R12. When the voltage of the electrical signal input to the first infrared receiving module 21 is greater than the interference voltage, causing the third switch Q1 to conduct, the first terminal (base) of the second switch Q2 is grounded through the fifth resistor R14 and the voltage divider circuit 222. The electrical signal with a voltage greater than the interference voltage is converted into a target level signal for reception by the second switch Q2, thus achieving signal filtering within the target voltage range. The aforementioned fifth resistor R14 and eighth resistor R12 ensure that the second switch Q2 operates within the normal voltage drop range. For example, the resistance value of the fifth resistor R14 can be 1 kΩ, and the resistance value of the eighth resistor R12 can be 10 kΩ.

[0047] In some embodiments, such as Figure 3 As shown, the voltage divider circuit 222 includes a first resistor R7 and a second resistor R13; the third terminal of the third switch Q1 is grounded through the first resistor R7 and connected to the first terminal of the second resistor R13, and the second terminal of the second resistor R13 is connected to the third power supply B3.

[0048] The voltage divider circuit 222 specifically includes a first resistor R7 and a second resistor R13. The third terminal (emitter) of the third switch Q1 is grounded through the first resistor R7 and connected to the first terminal of the second resistor R13. The second terminal of the second resistor R13 is connected to the third power supply B3. Through the first resistor R7 and the second resistor R13, a simple and stable voltage divider circuit 222 can be implemented, assisting the interference processing module 22 in generating a target level signal to control the second switch Q2. For example, the resistance of the first resistor R7 can be 200 Ω, and the resistance of the fifth resistor R13 can be 1 kΩ.

[0049] In some embodiments, such as Figure 3 As shown, the first infrared receiving module 21 includes: a first infrared receiving tube D92; the anode of the first infrared receiving tube D92 is connected to the second power supply B2, and the cathode of the first infrared receiving tube D92 is connected to the interference processing module 22 and grounded.

[0050] The first infrared receiving module 21 may specifically include a first infrared receiving tube D92 (photodiode), whose anode is connected to the second power supply B2. This second power supply B2 can be the same as the second power supply B2 connected to the second switch Q2 mentioned above; that is, the second power supply B2 is simultaneously connected to the anode of the first infrared receiving tube D92 and the second terminal of the second switch Q2. The cathode of the first infrared receiving tube D92 can be connected to the interference processing module 22, specifically through a sixth resistor R5 connected to the first terminal of the third switch Q1. The sixth resistor R5 ensures that the third switch Q1 operates within the normal voltage drop range, and its resistance value can be 1 kΩ. When the first infrared receiving tube D92 receives infrared light, it becomes conductive, connecting the second power supply B2 and the first terminal of the third switch Q1, allowing the first terminal of the third switch Q1 to receive an electrical signal. When the first infrared receiving tube D92 has no infrared light to receive, it becomes deactivated, and the second power supply cannot output a voltage signal to the first terminal of the third switch Q1. At this time, the interference processing module 22 has no input signal. By controlling the conduction and cutoff of the first infrared receiver tube D92 through infrared light signals, the electrical signal converted by the first infrared receiver tube D92 can be controlled to be input to the interference processing module 22, thereby further controlling the display content of the display screen of the display component; the cathode of the first infrared receiver tube D92 can also be grounded through the seventh resistor R1. Through the voltage division of the seventh resistor R1, the electrical signal converted by the first infrared receiver tube D92 can enter the interference processing module 22. For example, the resistance value of the seventh resistor R1 can be 1 kΩ.

[0051] In some embodiments, the alignment signal is an infrared light signal; such as Figure 4 As shown, Figure 4 The circuit structure diagram of the transmitting unit is shown. The transmitting unit includes: a second infrared transmitting module; the second infrared transmitting module is electrically connected to the display component and is used to transmit infrared light signals during the rotation of the display component around the first direction.

[0052] The transmitting and receiving units can use infrared communication, so the alignment signal can be an infrared light signal. Specifically, the transmitting unit can include a second infrared emitting module, the core component of which can be a light-emitting diode. The second infrared emitting module is electrically connected to the display component and can continuously emit infrared light signals as the display component rotates around the first direction. When the transmitting unit and the receiving unit are spatially coupled, the energy of the infrared light signal received by the receiving unit reaches its maximum, and the infrared light signal received by the receiving unit at this time is the alignment signal.

[0053] In some embodiments, such as Figure 4As shown, the second infrared emitting module includes: a second infrared emitting tube D1; the anode of the second infrared emitting tube D1 is connected to the fourth power supply B4, the cathode of the second infrared emitting tube D1 is grounded, and the second infrared emitting tube D1 is used to receive the output signal of the fourth power supply B4 and emit light during the rotation of the display component around the first direction to emit an infrared light alignment signal.

[0054] The second infrared emitting module may specifically include a second infrared emitting diode (LED) D1, whose anode is connected to a fourth power supply B4 via a ninth resistor R6. The ninth resistor R6 is used for current limiting to ensure that the second infrared emitting diode D1 operates within its normal voltage drop range. For example, the resistance of the ninth resistor R6 can be 1 kΩ. The cathode of the second infrared emitting diode D1 is grounded. It is understood that when the driving component of the display assembly (e.g., a motor) drives the display assembly to rotate, the fourth power supply B4 is always connected to the second infrared emitting diode D1. The voltage signal output by the fourth power supply B4 generates a voltage drop across the second infrared emitting diode D1, causing it to continuously emit infrared light signals. A voltage-stabilizing capacitor C47 can be connected in parallel with the branch containing the ninth resistor R6 and the second infrared emitting diode D1 to prevent drastic voltage changes in this branch.

[0055] In the display component, the second power supply B2, the third power supply B3, and the fourth power supply B4 can be powered by the same power supply. For example, the voltage amplitude output by the second power supply, the third power supply, and the fourth power supply B4 can all be 5V.

[0056] In some embodiments, such as Figure 5 As shown, Figure 5 The circuit structure diagram of the receiving unit is shown below. The receiving unit includes: a second infrared receiving module 13; the second infrared receiving module 13 is connected to the data transmitting end and is used to output a trigger command to the data transmitting end when it receives the infrared light signal emitted by the transmitting unit.

[0057] The receiving unit may include a second infrared receiving module 13, the core component of which may be a photosensitive element (photodiode or phototransistor). The second infrared receiving module 13 is connected to the data transmitting end. By receiving infrared light signals, the receiving unit can output a trigger command to the data transmitting end, thereby driving the data transmitting end to output display data.

[0058] In some embodiments, such as Figure 5 As shown, the second infrared receiving module 13 includes: a second infrared receiving tube D5; the anode of the second infrared receiving tube D5 is connected to the data transmitting end, the cathode of the second infrared receiving tube D5 is grounded, and the second infrared receiving tube D5 is used to obtain a trigger command by photoelectric conversion of the received infrared light signal emitted by the transmitting unit when it receives the infrared light signal, and output the trigger command to the data transmitting end.

[0059] The second infrared receiving module 13 may specifically include a second infrared receiving tube D5. The anode of the second infrared receiving tube D5 is connected to the data transmitting end (specifically, an MCU) through the IR_R port, and the cathode of the second infrared receiving tube D5 is grounded. When no infrared light signal is received, the second infrared receiving tube D5 is turned off, and the MCU pulls up the voltage of the IR_R port. When the second infrared receiving tube D5 receives an infrared light signal, the second infrared receiving tube D5 is turned on, and the MCU is grounded through the IR_R port, causing the voltage of the MCU's IR_R port to decrease, generating a trigger command. When the receiving unit and the transmitting unit are spatially coupled, Figure 4 The second infrared emitter D1 and Figure 5 When the second infrared receiver D5 is rotated to the alignment position, it starts to conduct after receiving infrared radiation. At this time, because the second infrared receiver D5 is conducting, the voltage of the IR_R port is pulled low. The MCU uses this voltage (trigger signal) to determine whether the control component and the display component have entered the optimal data transmission position.

[0060] In this embodiment, the data transmission circuit includes a detection link and a communication link. The detection link includes a transmitting unit and a receiving unit, and the communication link includes a data transmitting end and a data receiving end. By setting up a pair of transmitting and receiving units that can synchronously transmit and receive data with the data transmitting end and the data receiving end, a trigger command is generated when the receiving unit receives the alignment signal sent by the transmitting unit. This determines that the signal transmission area of ​​the communication circuit overlaps with the signal reception area of ​​the data receiving circuit, and that the data transmitting end and the data receiving end are in an optimal data interaction position. The data receiving end can receive display data with a stronger signal strength sent by the data transmitting end. Therefore, at this time, the data transmitting end responds to the trigger command and sends display data to the data receiving end for display component display, which can ensure the stability of data transmission between the display component and the control component and guarantee the data transmission effect.

[0061] In one embodiment, such as Figure 6 As shown, Figure 6 This is a block diagram of an atomizing device provided in an embodiment of the present application. The atomizing device includes any of the data transmission circuits described in the above embodiments.

[0062] The atomizing device includes a control component, a display component, and a data transmission circuit as described in any of the above embodiments. The display component is configured to rotate relative to the control component. The beneficial effects of the atomizing device are similar to or the same as those of the data transmission circuit described above, and will not be repeated here.

[0063] In one embodiment, such as Figure 7 As shown, Figure 7This application provides a flowchart of a data transmission method according to an embodiment of the present application. The method is applied to any of the data transmission circuits described in the preceding embodiment or the atomizing device described in the following embodiment. The method includes: Step 101: In the data transmission circuit, the data transmitting end on the communication link responds to the trigger command generated by the receiving unit on the detection link and transmits display data to the data receiving end on the communication link; the trigger command is data generated by the receiving unit when it receives the alignment signal transmitted by the transmitting unit on the detection link during rotation.

[0064] In the data transmission method provided in this application embodiment, the detection link uses infrared light as an alignment signal, and the communication link uses infrared light to transmit display data. The specific process is as follows: After the atomizing device is powered on, the emitting unit (infrared emitting tube) located on the display component continuously emits infrared alignment signals at a preset frequency; when the display component rotates, the emitting unit rotates synchronously around the rotation axis with the display component.

[0065] The receiving unit (infrared receiver tube) of the control component detects the intensity of the incident infrared light signal in real time. When the display component rotates to the point where the transmitting unit and the receiving unit are spatially coupled, the intensity of the infrared light signal detected by the receiving unit reaches the preset trigger threshold, and then a trigger command is generated and sent to the data transmitting end on the control component side.

[0066] After receiving the trigger command, the data transmitter (infrared communication transmitter module, which may include an infrared transmitter tube) on the control component side responds to the trigger command, retrieves the latest display data stored in the control component, modulates the display data into an infrared light signal, and then transmits it to the outside. At this time, because the data transmitter and data receiver are perfectly aligned when the transmitter and receiver are coupled, the transmission path of the infrared communication signal is optimal and the signal strength is the highest.

[0067] After receiving the infrared communication signal, the data receiving end (infrared communication receiving module, which may include an infrared receiving tube) of the display component demodulates the display data and transmits the display data to the display element of the display component to refresh the display content of the screen.

[0068] This method avoids the transmission process when the communication link is misaligned by first confirming the alignment status through detection link and then triggering the data transmission timing design. This effectively improves the data transmission stability between the rotating display component and the fixed control component, avoids problems such as display stuttering and content corruption, and significantly improves the display effect of the display component.
