Description

Technical Field

[0001] This utility model relates to a temperature measurement and display control module. Background Technology

[0002] Currently, non-contact temperature measurement technology has been applied in fields such as kitchen appliances, for example, in range hoods to achieve automatic on / off and temperature adjustment. However, existing solutions typically separate the temperature measurement module from the display and control module, for example, placing the display and control components on the display panel. This separate design makes it impossible to effectively indicate the specific functional status of the temperature measurement module to the user, resulting in a less intuitive user experience and poor interactivity. Users find it difficult to intuitively understand the current operating status of the temperature measurement module (such as on, off, or temperature level), affecting the overall interactive experience of the product. Therefore, there is a need for an integrated module that highly integrates temperature measurement, touch control, and status display functions to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a highly integrated and intuitive temperature measurement and display control module to overcome the shortcomings of the above-mentioned technologies.

[0004] To achieve the above objectives, this utility model designs a temperature measurement and display control module, including a filter, a thermopile sensor, and a PCB board. It also includes conductive foam, a ring-shaped lamp post, and a metal sleeve. The metal sleeve is vertically mounted on the PCB board, serving as the structural center of the temperature measurement and display control module and providing mechanical support. Its lower end face is electrically connected to the PCB board. The thermopile sensor is housed inside the metal sleeve and electrically connected to the PCB board. The thermopile sensor receives external infrared energy radiation and converts the thermal signal into an electrical signal for output. The lower end face of the conductive foam is adhesive, allowing it to adhere tightly to the upper end face of the metal sleeve. The filter is tightly attached to the conductive foam, covering the opening at the top of the conductive foam. The filter is conductive and, in addition to filtering out ineffective energy, also serves as a touch button. When a user touches the filter, the human body charge passes sequentially through the filter, conductive foam, and metal sleeve to the PCB board. The ring-shaped lamp post is sleeved outside the metal sleeve and conductive foam, and it contains built-in LED beads with its lower end face electrically connected to the PCB board.

[0005] A further solution is a temperature measurement and display control module designed in this utility model, wherein the metal sleeve is made of conductive metal material, which is used to protect the thermopile sensor from thermal shock while also serving as a conductive post to connect the conductive foam and the PCB board.

[0006] A further solution is a temperature measurement and display control module designed in this utility model. A touch control circuit is set on the PCB board, integrating a central processing unit U1 and a touch chip U2. A thermopile sensor is electrically connected to the touch control circuit. The thermopile sensor contains a thermopile chip and an NTC sensor. The NTC sensor performs differential sampling through pins 6 and 7 of U1, while the thermopile chip performs differential sampling through pins 8 and 9 of U1. The thermal sensing signal is processed by U1 and converted into temperature data. LEDs are connected to the display output pins 25, 26, 27, and 28 of U1. The touch chip U2 detects the electrical signal obtained by SW1 sensed through the touch filter. When a touch signal is received, U2 outputs a high level, and U1 controls pins 25, 26, 27, and 28 to light up the LEDs, allowing the thermopile sensor to operate normally. When another touch signal is received, U1 controls the LEDs to turn off, and the thermopile sensor stops working.

[0007] A further improvement is that the temperature measurement and display control module designed in this utility model has a filter material that can transmit both visible light and infrared light.

[0008] This invention discloses a temperature measurement and display control module that highly integrates temperature measurement, touch sensing, and status indication functions into a compact module. The module boasts an ingenious structure and excellent functional synergy. The metal sleeve serves multiple functions, including structural support, thermal protection, and touch conductivity, significantly improving the module's reliability, accuracy, and user experience. Users can directly operate the module at the temperature measurement point and receive intuitive status feedback, resulting in a simple and efficient interaction process. Attached Figure Description

[0010] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0011] Example 1.

[0012] Please refer to Figure 1 This embodiment describes a temperature measurement and display control module, including a filter 1, a thermopile sensor 5, a PCB board 6, conductive foam 2, a ring lamp post 3, and a metal sleeve 4. Please refer to [reference needed]. Figure 2 and Figure 3 The metal sleeve 4 is vertically mounted on the PCB board 6, with its lower end face electrically connected to the PCB board 6. The thermopile sensor 5 is housed inside the metal sleeve 4 and electrically connected to the PCB board 6. The metal sleeve 4 is made of conductive metal material and serves to provide mechanical support for the entire temperature measurement and display control module and protect the thermopile sensor 5 from thermal shock. The lower end face of the conductive foam 2 is adhesive, allowing it to adhere tightly to the upper end face of the metal sleeve 4. The filter 1 is tightly attached to the conductive foam 2 and covers the opening above the conductive foam 2. The annular lamp post 3 is sleeved on the outside of the metal sleeve 4 and the conductive foam 2. The annular lamp post 3 has a built-in LED light and its lower end face is electrically connected to the PCB board 6. The filter 1 is tightly attached to the conductive foam 2 and covers the opening at the top of the conductive foam 2. The filter 1 is conductive and, in addition to filtering out invalid energy, also serves as a touch button. When a user touches the filter 1, the human body charge passes through the filter 1, the conductive foam 2, and the metal sleeve 4 in sequence to reach the PCB board 6. The thermopile sensor 5 receives external infrared energy radiation and converts the thermal signal into an electrical signal for output. The material of the filter 1 can transmit both visible light and infrared radiation.

[0013] Please refer to Figure 4 A touch control circuit is provided on the PCB board 6. The touch control circuit integrates a central processing unit U1 and a touch chip U2. The thermopile sensor 5 (S1 in the circuit diagram) is electrically connected to the touch control circuit. The central processing unit U1 integrates ADC sampling and conditioning functions. S1 is the thermopile sensor 5, which contains a thermopile chip and an NTC sensor. The NTC sensor performs differential sampling through pins 6 and 7 of the central processing unit U1, while the S1 thermopile sensor 5 performs differential sampling through pins 8 and 9. The thermal sensing signal is calculated and converted into temperature data after passing through the central processing unit U1. The display output pins 25, 26, 27, and 28 of the central processing unit U1 are respectively connected to LED1, LED2, and LED3 in the ring-shaped light column 3. Touch chip U2 is used to detect electrical signals from SW1. SW1 is a filter, which is replaced by metal sleeve 4 here. When a touch signal is received, U2 outputs a high level. At this time, the central processing unit U1 controls pins 25, 26, 27, and 28 respectively to light up the LEDs of LED1, LED2, and LED3, and the S1 thermopile sensor 5 works normally. When a touch signal is received again, the central processing unit U1 controls the LEDs to turn off, and the S1 thermopile sensor 5 stops working.

[0014] Please refer to Figure 5 Infrared energy reaches thermopile sensor 5 through filter 1. The infrared energy is converted into a microvolt-level small signal and then sent to ADC signal conditioning unit. The ADC signal conditioning unit converts the analog signal into a digital signal and then sends it to central processing unit U1. The display driver is used to display whether the current temperature measurement display control module is on or off, or to display different color states according to the temperature signal output by central processing unit U1.
