Description

Technical Field

[0001] This utility model belongs to the field of electronic circuits and LED technology, specifically a smart heating box display structure with segmented indicator lights. Background Technology

[0002] A heating box is a device used to heat items or maintain a specific temperature. It typically consists of a shell, heating element, temperature control system, and insulation material. Its core function is to convert electrical energy into heat energy through a heating element, such as a heating wire, PTC ceramic heater, or infrared heater, to heat or keep the items inside the box warm. Existing heating boxes have rudimentary displays, and some lack a heating indicator function altogether. For example, the "Heated Meal Box" disclosed in patent document "CN114176298A" uses a method where the first roll abutment and the second roll abutment abut against each other to improve the connection tightness of the heated meal box. However, from the attached... Figure 1 -5 indicates that the heated food container lacks a display screen, making it difficult for users to estimate the remaining heating time, causing inconvenience and making it difficult for users to manage their time effectively.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please refer to Figure 1-4 ;

[0020] A smart heating box display structure with segmented indicator lights includes a heating box body 1. The heating box body 1 houses an MCU module 11, a control module 2, and a timing module 3. In this embodiment, the control module 2 and the timing module 3 are packaged in a single chip, preferably a TM1640 chip. The timing module 3 has several positive and negative pins connected together. An LED strip module 4 is positioned between the positive and negative pins. The output of the MCU module 11 is electrically connected to the input of the control module 2. Specifically, the output of the MCU module 11 is connected to the DIN and SCLK pins of the TM1640 chip. The MCU module 11 transmits timing signals and data signals to the control module 2. The control module 2 controls the timing module 3 to turn on or off its positive and negative pins based on the timing and data signals. The timing module 3 controls the LED strip module 4 to be either constantly green, flashing red, or off. Through the integration of the MCU module 11... 1. The control module 2 and timing module 3, packaged with the TM1640 chip, along with the LED strip module 4, enable precise control of the segmented indicator lights. The MCU module 11 transmits data and timing signals to the TM1640 chip via DIN and SCLK pins. The control module 2 precisely turns the positive and negative pins on or off according to the signals, thereby driving the LED strip module 4 to display a solid green light, flashing red light, or off state, indicating the working status of the heating box. The high integration of the TM1640 chip simplifies circuit design and reduces power consumption and production costs. The diverse color and flashing display methods of the LED strip module 4 intuitively reflect the equipment status, improving user experience and operational safety. It is particularly suitable for intelligent heating equipment requiring clear status indication. Furthermore, the heating box body 1 is equipped with a display screen body 5, which is rotatably connected to the heating box body 1. The display screen body 5 is equipped with an adjustment module 6, and the MCU module 11 is equipped with a timing module 7. The adjustment module 6 is used to adjust the timing module 7.

[0021] Specifically, the light strip module 4 includes several display lights 41 arranged linearly. In this embodiment, the number of display lights 41 is ten. When heating begins, the first segment starts flashing red light. When one-tenth of the heating is completed, the first segment becomes constantly lit, which is green light. Then the second segment starts flashing red light. When two-tenths of the heating is completed, the second segment also becomes constantly lit green light. Then the third segment starts flashing red light. This cycle continues until the tenth segment is heated and turns green. At this point, it is a green light strip. Heating is complete, allowing the user to have a predictable waiting time.

[0022] In this embodiment, the MCU module 11 is equipped with a temperature module 8. The output terminal of the adjustment module 6 is electrically connected to the input terminal of the temperature module 8. The MCU module 11 is electrically connected to the temperature module 8. The adjustment module 6 is used to adjust the target temperature value of the temperature module 8. The temperature module 8 transmits the target temperature value to the MCU module 11. The adjustment module 6 is electrically connected to the input terminal of the temperature module 8 through its output terminal. The user can set the target temperature value of the temperature module 8 through the adjustment module 6. After receiving the input signal from the adjustment module 6, the temperature module 8 transmits the target temperature value to the MCU module 11, realizing the precise setting and dynamic feedback of the target temperature. The adjustment module 6 allows the user to flexibly adjust the target temperature value of the temperature module 8.

[0023] In this embodiment, the positive pins include SEG1, SEG2, SEG3, SEG4, and SEG5, and the negative pins include DIG12, DIG13, DIG14, DIG15, and DIG16. The indicator light 41 includes a red diode, a green diode, and a blue diode. One end of the anode of the red diode is electrically connected to the SEG3 pin, one end of the anode of the green diode is electrically connected to the SEG2 pin, and one end of the anode of the blue diode is electrically connected to the SEG1 pin. When the indicator light 41 needs to display green, the MCU module 11 generates corresponding timing signals and data signals according to the set target temperature value or working state, and transmits them to the control module 2 of the TM1640 chip through the DIN and SCLK pins. After the control module 2 parses the signals, it controls the timing module 3 to conduct the positive pin SEG3 and the corresponding negative pin, such as one of the DIG12, DIG13, DIG14, DIG15, or DIG16 pins, to form a complete current loop, thereby lighting up the green diode.
