Description

Technical Field

[0001] The utility model relates to the field of novel electric shock demonstrator, in particular to a novel electric shock demonstrator. Background Art

[0002] Electric shock is the common name for electric injury, which usually refers to tissue damage and functional disorders caused by the human body directly touching the power source or high voltage electricity passing through the air or other conductive media to transfer current through the human body. In severe cases, cardiac and respiratory arrest may occur. High voltage electricity exceeding 1000V (volts) can also cause burns. Lightning injury (lightning strike) belongs to the category of high voltage electricity injury. There are many reasons for electric shock injuries, mainly lack of knowledge on safe use of electricity, installation and maintenance of electrical appliances and wires not in accordance with regulations, and hanging clothes on wires. High temperature, high humidity and sweating reduce the surface resistance of the skin, which can easily cause electric injury. Electric injuries can be caused by wires breaking and falling on the human body in accidents, or by lightning strikes when taking shelter under a tree or using an iron-handled umbrella during a thunderstorm.

[0003] The part about electric shock in junior high school physics textbook only talks about two types of electric shock: fire-zero and fire-ground. It is not comprehensive enough. Moreover, teachers cannot personally use AC electricity to demonstrate to students, which is not conducive to students' understanding of electric shock.

[0004] After exploring the existing Chinese patent: an electric shock demonstrator (publication number: CN104134385A) includes a wooden board, a small light bulb, a transformer, a metal rod, and a metal plate. The metal plate is placed on the wooden board. The transformer is installed on the wooden board, one end of which is connected to the mains, and the other end leads to the live wire and the neutral wire. The metal rod is installed at the lower left of the wooden board, and the metal rods are connected with steel wires. A small light bulb is installed on the steel wire, and the live wire and the neutral wire are connected with the steel wire. It also includes a toy man and a tree. The toy man's head is provided with iron wire, the left and right hands are provided with metal hooks, the soles of the feet are provided with copper plates, the left and right hand metal hooks are provided with LED light bars, the left hand metal hooks and the left foot copper plates are provided with LED light bars, the abdomen is provided with neon tubes, and the neon tube pins pass through the thighs and are connected to the soles of the feet copper plates. The tree is installed in the upper left corner of the wooden board. The electric shock demonstrator is simple and safe to operate, and the simulated phenomenon is intuitive.

[0005] The above patent is simple and safe to operate, and the simulation phenomenon is intuitive, but it needs to be moved frequently for demonstration during use. In the above patent, the staff can only hold the device by hand for movement. In case of a collision, the device will fall and cause damage to the device. Therefore, it is necessary to invent a new type of electric shock demonstrator to solve the above problem. Utility Model Content
