BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 This is a circuit diagram of the utility model. DETAILED DESCRIPTION

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0012] Example 1

[0013] The preferred embodiment of the wire break alarm device experimenter provided by the utility model is as follows Figure 1 As shown: a disconnection alarm device experimenter, including a circuit board, on which a reed switch, a potentiometer and a buzzer are respectively installed, the two ends of the reed switch are respectively connected with a black clip wire and a yellow clip wire through electric wires, the two ends of the potentiometer are respectively connected with a red clip wire and another yellow clip wire through electric wires, through the set disconnection alarm circuit, the disconnection alarm can be effectively demonstrated in the teaching process, which is beneficial for students to effectively observe the circuit structure, improve teaching efficiency, meet people's work needs, and is worthy of popularization and use.

[0014] When in use, this application uses a normally open reed switch, connects the two ends of the reed switch to a black clip wire and a yellow clip wire, and connects the two ends of the potentiometer to a red clip wire and another yellow clip wire. After the reed switch is away from the magnet, adjust the potentiometer to make the buzzer sound. At this time, bring the magnet close to the reed switch, and the alarm circuit does not work. During this process, connect a thin copper wire between the black clip wire and the yellow clip wire. When the thin copper wire breaks, the circuit will alarm.

[0015] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0016] It should be noted that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the utility model.

[0017] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
