Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrical instruments, and particularly relates to an electrical instrument with an alarm function. Background Technique
[0002] Electrical instruments are the general term for general instrument devices used to measure or test voltage, current, resistance, or power.
[0003] For example, the Chinese patent with the publication number CN221039137U discloses an electrical instrument that is easy to install, including a storage component, and an instrument is placed inside the storage component. By rotating the screwing plate in the utility model, the screwing plate will drive the vertical insertion column, the horizontal connecting plate, and the vertical convex column to rotate. Since the vertical convex column is inserted into the waist-shaped hole, when the vertical convex column rotates, the vertical convex column will drive the strip-shaped moving plate, the square insertion plate, and the loop-shaped baffle to move inward, and at the same time, the return spring will contract and become shorter. Then, the instrument and the installation component are placed inside the instrument box body. When the installation component contacts the inner bottom surface of the instrument box body, the screwing plate is released at this time. Due to the elastic force of the return spring, when the screwing plate is released, the square insertion plate will move outward at this time, and the outer end of the square insertion plate will be inserted into the corresponding square installation hole, thereby realizing the installation of the instrument.
[0004] The above patent has the following problems:
[0005] There are some disadvantages in the use of this patent. For example, during the long-term use of the above electrical instrument, a large amount of heat will be generated inside it. Due to the lack of a heat dissipation component in the electrical instrument, the heat generated by the electrical instrument will accumulate a large amount inside the electrical instrument, which may damage the internal electronic components and reduce the service life of the electrical instrument. In view of this, we propose an electrical instrument with an alarm function. Content of the Utility Model
[0006] The purpose of the utility model is to provide an electrical instrument with an alarm function to solve the problems raised in the above background technique.
[0007] In view of this, the utility model provides an electrical instrument with an alarm function, including:
[0008] An electrical instrument and a housing, the housing is fixedly connected to the electrical instrument, and the electronic components of the electrical instrument in the housing are arranged in the inner cavity of the housing. Two first through grooves communicating with the inner cavity of the housing are respectively opened on both sides of the housing. A support rod is fixedly connected in the first through groove, and a fan is rotatably connected to the side of the support rod close to the electrical instrument;

By setting the dust-proof net, it is ensured that the two dust-proof nets can prevent the dust from the outside from entering the electrical instrument. By setting the drive assembly, it is ensured that the user can drive the two fans to rotate through the drive assembly, so that the two fans dissipate heat from the electronic components of the electrical instrument inside the housing.

By setting the alarm, it is ensured that when the temperature detection probe of the temperature detector detects that the temperature inside the electrical instrument is relatively high, the temperature detector will start the alarm, so that the alarm gives an alarm, enabling the user to know that the temperature inside the electrical instrument is too high.

A rotating rod is rotatably connected inside the second through groove, and both ends of the rotating rod extend into the two movable grooves and are respectively fixed to the two second sprockets;

[0023] In this technical solution, it is ensured that both ends of the rotating rod can rotate normally in the two movable grooves.
[0024] In the above technical solution, further, the output shaft of the motor is rotatably connected to the first rotating groove.
[0025] In this technical solution, it is ensured that the output shaft of the motor can rotate normally in the first rotating groove.
[0026] In the above technical solution, further, the single-chip microcomputer is electrically connected to the motor.
[0027] In this technical solution, it is ensured that the single-chip microcomputer can start the motor.
[0028] In the above technical solution, further, the temperature detector is electrically connected to the alarm, and the temperature detector is electrically connected to the single-chip microcomputer.
[0029] In this technical solution, it is ensured that the temperature detector can start the alarm to make the alarm sound, and it is ensured that the temperature detector can start the motor through the single-chip microcomputer.

[0032] 2. The electrical instrument with an alarm function, through the single-chip microcomputer, temperature detector and motor provided, ensures that the temperature detection probe on the temperature detector can detect the temperature generated by the electrical instrument during long-term operation.
