Detailed Embodiments

[0016] Next, through embodiments and in combination with the drawings, the technical solutions of the present utility model will be further described.

[0017] Embodiment:

[0018] In this embodiment, a button battery heating detection device, as Figure 1 shown, includes a bottom plate 1. An adjustable load circuit, a plurality of battery slots 3 with different sizes, and cover plates 9 corresponding to each battery slot are provided on the bottom plate 1. A plurality of temperature sensor probes for detecting the side temperature of the button battery in the battery slot are provided on the cover plate.

[0019] One end of the battery slot 3 is provided with a fixed conductive sheet 4, and the second end of the battery slot is provided with a movable conductive sheet. The movable conductive sheet includes a conductive metal sheet 6 and a conductive spring 7. The conductive metal sheet 6 is fixedly arranged at the first end of the conductive spring 7, and the second end of the conductive spring 7 is electrically connected to the second end of the battery slot 3. Each battery slot can hold a plurality of button batteries 5, and the cooperation with the movable conductive sheet enables the serial number of the batteries to be arbitrarily changed during detection. In this embodiment, each battery slot 3 is connected to the adjustable load circuit through a changeover switch 2. The changeover switch 2 is a single-pole multi-throw switch. The stationary contact of the changeover switch 2 is electrically connected to the adjustable load circuit, and each moving contact of the changeover switch 2 is respectively electrically connected to each battery slot.

[0020] The adjustable load circuit includes an ammeter, a rheostat, and a light-emitting diode connected in series in sequence. In addition, a voltmeter is connected in parallel across both ends of the adjustable load circuit. The load of the adjustable load circuit can be changed through the rheostat, thereby changing the output power of the button battery. The output power of the button battery can be accurately obtained through the ammeter and the voltmeter. The light-emitting diode serves as an indicator to indicate whether the button battery is depleted of power.

[0021] The cover plate is arc-shaped. The first side of the cover plate is rotatably arranged on the bottom plate. The second side of the cover plate is provided with a first plate body, and the bottom plate is provided with a second plate body corresponding to the second side of the cover plate. Both the first plate body and the second plate body are provided with Velcro, and the first plate body and the second plate body are fixed through the Velcro. A plurality of partition edges 11 are arranged on the inner wall of the cover plate. The distance between adjacent partition edges 11 is the thickness of the button battery in the corresponding battery slot of the cover plate. When the cover plate covers the battery slot, the partition edges are embedded into the gaps between adjacent two button batteries, and the temperature sensor probe is fixedly arranged in the area between adjacent two partition edges. After the cover plate covers the battery slot, the inner wall of the cover plate is in contact with the side surface of the button battery, so that the temperature sensor probe on the cover plate is in contact with the side surface of the button battery in the battery slot to detect the temperature of the button battery. At the same time, the first plate body and the second plate body are adhered through the Velcro to fix the cover plate to ensure that the cover plate is not separated from the button battery due to misoperation or collision, affecting the detection accuracy of the temperature sensor probe. In addition, in this embodiment, in order to obtain the temperature of each button battery in a timely manner, a display screen 8 for displaying the data collected by each temperature sensor probe is also arranged on the bottom plate.
