Abstract
Description
Technical Field
[0001] This utility model relates to the field of infrared heating source equipment, and in particular to a heating panel mounting base and an infrared heating plate. Background Technology
[0002] Infrared heating plates are non-contact heating devices commonly used in environments requiring uniform temperature or corrosion resistance. An infrared heating plate typically consists of a heating panel and a mounting base for mounting the panel. The heating panel generates infrared radiation to achieve heating after being connected to a 220V power supply. The heating panel needs to be connected to electrodes. Traditionally, mounting holes are drilled on the surface of the infrared heating plate, and the power cord is directly fixed to the electrodes using screws. This method has the following drawbacks:
[0003] 1. The hole-opening process can easily lead to local stress concentration in the infrared heating plate, especially in the edge area of the hole. Under mechanical load or thermal shock, brittle fracture is likely to occur, reducing the structural strength and reliability.
[0004] 2. The gap between the mounting hole and the screw lacks an effective seal. When the equipment is placed flat or tilted, liquid (such as the solution in water quality testing) can easily seep into the interior along the gap, causing electrode short circuits or component corrosion, which poses a safety hazard.
[0005] In addition, most existing infrared heating devices adopt an open-loop temperature control method, which indirectly controls the temperature by adjusting the input voltage. The voltage-controlled temperature method cannot provide real-time feedback of the actual temperature and is affected by factors such as environmental heat loss and changes in heating plate resistance. The temperature control accuracy is low (the deviation often exceeds ±10℃), making it difficult to meet the needs of precision heating (such as constant temperature control of digestion reactions).
[0006] The aforementioned defects severely restrict the application of infrared heating plates in precision instruments, and there is an urgent need for an installation and connection method that takes into account structural strength, sealing performance, and temperature measurement accuracy.

[0007] The purpose of this utility model is to provide a heating panel mounting base and an infrared heating plate to solve the problems existing in the prior art.

The side of the heat-transfer insulating sheet facing the opening of the receiving groove is the temperature measuring end. The body is connected to a transmission part for transmitting signals outward.
[0015] In one embodiment, the area of one side of the heat-transfer insulating sheet that is attached to the body is larger than the end face area of the first end of the body. The second limiting spring is disposed in the sensor seat, with the first end of the second limiting spring abutting against the body and the first end of the second limiting spring abutting against the sensor seat.

[0032] The purpose of this utility model is to provide a heating panel mounting base and an infrared heating plate to solve the problems existing in the prior art. It can install the heating panel without the need for a hole-making process and ensure a stable power supply to the heating panel.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0034] Example 1
[0035] like Figures 1-6As shown, this utility model provides a heating panel mounting base, including a base 1, on which a receiving groove 10 is provided. The receiving groove 10 has a conductive device mounting position 101 and a temperature measuring device mounting position 102. The conductive device 2 is disposed within the conductive device mounting position 101, and has a power supply terminal and a wiring terminal. The power supply terminal is located within the receiving groove 10 and faces the opening of the receiving groove 10. The temperature measuring device 3 is disposed within the temperature measuring device mounting position 102, and has a temperature measuring terminal, which is located within the receiving groove 10 and faces the opening of the receiving groove 10. The receiving groove 10 is used to mount a heating panel 4. The side of the heating panel 4 with electrodes enters the receiving groove 10 through the opening. The power supply terminal of the conductive device 2 located within the receiving groove 10 can contact the electrodes of the heating panel 4, achieving conductivity. This eliminates the need for drilling holes in the heating panel 4, ensuring the integrity of the heating panel 4 and preventing obvious, easily cracked areas or leakage holes. The measuring end of the temperature measuring device 3 can be directly attached to the heating panel 4 to achieve reliable contact heat conduction. The measured temperature of the temperature measuring device 3 can accurately reflect the real-time temperature of the heating panel 4, and the temperature measurement result is intuitive and accurate.
[0036] In one embodiment, the conductive device 2 includes a terminal block 201 and a conductive element 202. The terminal block 201 is disposed within the conductive device mounting position 101, and the conductive element 202 is disposed within the terminal block 201. One end of the conductive element 202 exposed in the receiving groove 10 is a conductive end. The terminal block 201 is used to mount the conductive element 202, serving a fixing function. Simultaneously, the terminal block 201 is made of insulating material to prevent breakdown of the conductive element 202 when energized, ensuring safe use.
[0037] In one embodiment, the conductive element 202 is a conductive post. The first end of the conductive post is a power supply terminal, extending beyond the top surface of the terminal block 201. The second end of the conductive post is a connection terminal, extending beyond the bottom surface of the terminal block 201. The first end of the conductive post extending beyond the terminal block 201 ensures that, during the installation of the heating panel 4, the power supply terminal first contacts the electrodes of the heating panel 4, preventing poor contact. The second end of the conductive post extending beyond the terminal block 201 facilitates connection to an external power supply wire. It is understood that the conductive element 202 can also be other types of electrode structures.
[0038] In one embodiment, the conductive post includes a post head 2021 and a post body 2022. The bottom surface of the post head 2021 is fixedly connected to the top surface of the post body 2022. The bottom surface area of the post head 2021 is larger than the top surface area of the post body 2022. The top surface of the post head 2021 is the power supply terminal, and a portion of the post head 2021 extends out of the top surface of the terminal block 201. The bottom surface of the post body 2022 is the wiring terminal, and a portion of the post body 2022 extends out of the bottom surface of the terminal block 201. A first limiting spring 203 is sleeved on the post body 2022. The first end of the first limiting spring 203 abuts against the bottom surface of the post head 2021, and the second end of the first limiting spring 203 abuts against the inner side of the bottom surface of the terminal block 201. Under normal conditions, the first limiting spring 203 is in a compressed state. Here, "normal state" refers to the state where the conductive post is fixedly installed in the terminal block 201 after the heating panel mounting base is assembled. The compressed first limiting spring 203 can provide a thrust to the column head 2021. When the conductive column is kept in a fixed state, the first limiting spring 203 does not function. When the conductive column is loose, the first limiting spring 203 can push the column head 2021 to fit against the heating panel 4 to avoid poor contact.
[0039] In one embodiment, the temperature measuring device 3 includes a temperature sensor 301 and a sensor base 302. The temperature sensor 301 is disposed in the sensor base 302, and the first end of the temperature sensor 301 is the temperature measuring end.
[0040] In one embodiment, the temperature sensor 301 includes a body 3011 and a heat-transfer insulating sheet 3012. The body 3011 has a sheet-like structure and is disposed on the sensor base 302. The heat-transfer insulating sheet 3012 covers the surface of the body 3011 and is bonded to the surface of the body 3011. The side of the heat-transfer insulating sheet 3012 facing the opening of the receiving groove 10 is the temperature measuring end. The body 3011 is connected to a transmission part for transmitting signals outward. When an abnormal discharge occurs in the heating panel 4, the heat-transfer insulating sheet 3012 can prevent the body 3011 from being broken down by the current. The heat-transfer insulating sheet 3012 can be a ceramic sheet or made of other materials with good heat transfer and insulation properties.
[0041] In one embodiment, the area of one side of the heat transfer insulating sheet 3012 that is combined with the body 3011 is larger than the end face area of the first end of the body 3011. The second limiting spring 303 is disposed inside the sensor seat 302. The first end of the second limiting spring 303 abuts against the body 3011 and the sensor seat 302. Under normal conditions, the second limiting spring 303 is compressed. "Normal conditions" here refers to the state where the body 3011 is fixedly installed in the sensor seat 302 after the heating panel mounting base is assembled and the heating panel 4 is installed. When no pressure is applied, the first end of the second limiting spring 303 extends out of the sensor seat 302. The heating panel 4 presses against the heat transfer insulating sheet 3012 and the body 3011, causing the second limiting spring 303 to compress. The compressed second limiting spring 303 provides a thrust to the body 3011, which in turn presses against the heat transfer insulating sheet 3012. At this time, the heat transfer insulating sheet 3012 adheres to the heating panel 4, and the body 3011 adheres to the heat transfer insulating sheet 3012, preventing poor contact. In one embodiment, the body 3011 is a thermocouple. It is understood that the body 3011 can also be other hardware capable of temperature measurement. The body 3011 can be bonded to the first end of the second limiting spring 303, or other fixed connection methods can be used to connect the body 3011 and the second limiting spring 303.
[0042] In one embodiment, there are two conductive devices 2, which are disposed at the bottom of the receiving groove 10, and one temperature measuring device 3, which is disposed at the bottom of the receiving groove 10 and located in the middle position.
[0043] Example 2
[0044] like Figures 1-6 As shown, this utility model also provides an infrared heating plate, including a heating panel 4 and the heating panel mounting base mentioned above. The heating panel 4 is bonded and fixed in the receiving groove 10. The electrodes of the heating panel 4 are in contact with the power supply end of the conductive device 2, and the heating panel 4 is in contact with the temperature measuring end of the temperature measuring device 3.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).
