Description
Technical Field
[0001] This utility model belongs to the field of teaching aids technology, specifically relating to an energy conversion demonstration device for teaching. Background Technology
[0002] Energy conversion is a core concept in nature and engineering, demonstrating the transformation of energy from one form to another, and embodying the transfer and conservation of energy between different forms. It is a fundamental principle in fields such as physics, chemistry, and engineering. To help students intuitively understand this abstract concept, experiments are often used to translate theory into practice. However, most existing experimental equipment consists of single-device setups, requiring the preparation of multiple sets of equipment, which wastes time and thus affects the pace of class, exhibiting certain limitations. Utility Model Content
[0003] The purpose of this invention is to solve the problems in the background technology and provide a teaching energy conversion demonstration device. This device can simultaneously demonstrate multiple disciplines and perform multiple energy transfers, making energy conversion more intuitive.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A teaching energy conversion demonstration device includes a pressurized sprayer, a digital thermometer, a first fan, a storage bottle, and a second fan. The pressurized sprayer has three conduits installed on its upper part, each with a switch. The end of conduit one away from the pressurized sprayer is connected to the digital thermometer. The nozzle of the pressurized sprayer faces the first fan. A generator motor is connected to the shaft of the first fan, and a light bulb is connected to the generator motor. The storage bottle is connected to the pressurized sprayer through conduit two, and conduit three is connected to the blades of the second fan.
[0006] The body of the pressurized spray bottle is made of transparent material.
[0007] The storage bottle contains a liquid medium, and the pressurized sprayer is pre-filled with a liquid or solid medium. The two media stored in the storage bottle and the pressurized sprayer will undergo a chemical reaction.
[0008] The beneficial effects of the energy conversion demonstration device for teaching provided by this utility model are as follows: by setting three conduits on the pressurized spray bottle and connecting them to a digital thermometer, a storage bottle and a second fan respectively, and pointing the nozzle of the spray bottle towards the first fan, the demonstration device can intuitively reflect the conversion process of multiple energy states.

[0012] like Figure 1 As shown, the energy conversion demonstration device for teaching provided in this embodiment includes a pressurized spray bottle 1, a digital thermometer 2, a first fan 3, a storage bottle 6, and a second fan 7. The pressurized spray bottle 1 is existing technology. For ease of observation, the body 11 of the pressurized spray bottle 1 is made of transparent material. A piston 13, a handle 14, and a spout 12 are installed at the mouth of the pressurized spray bottle 1. Pressing the piston 13 can pressurize the spray bottle, and pressing the handle 14 can release the pressure from the spout 12. Three guide tubes are installed on the upper part of the pressurized spray bottle 1, and a switch is installed on each guide tube. The end of the first guide tube 15 away from the pressurized spray bottle 1 is connected to the digital thermometer 2. The pressurization... The nozzle of spray bottle 1 faces the first fan 3. The distance between the nozzle 12 and the first fan 3 is such that the blades of the first fan 3 are within the surface of the air ejected from the nozzle. A generator motor 4 is connected to the shaft of the first fan 3, and a light bulb 5 is connected to the generator motor 4. The connection between the first fan 3 and the generator motor 4, and the connection between the generator motor 4 and the light bulb 5 are existing technologies and will not be described in detail here. The storage bottle 6 is connected to the pressurized spray bottle 1 through the second conduit 16. The storage bottle 6 contains white vinegar, and the pressurized spray bottle 1 is pre-filled with baking soda. The white vinegar and baking soda will produce a chemical reaction when mixed. The third conduit 17 is connected to the blades of the second fan 7.
[0013] The method of using this utility model is as follows:
[0014] Experiment 1: Kinetic energy is converted into internal energy. By pressing the piston 13 repeatedly, the pressure of the pressurized spray bottle 1 can be increased. The gas pressure inside the pressurized spray bottle 1 increases, which will increase the temperature. At this time, when the switch on the conduit 15 is turned on, the reading of the digital thermometer 2 can be observed to rise. This process indicates that the kinetic energy of the pressurized gas is converted into the internal energy of the air.
[0015] Experiment 2: Kinetic energy is converted into wind energy. Based on Experiment 1, press the handle 14. At this time, the air in the pressurized spray bottle 1 is sprayed out through the nozzle 12 toward the first fan 3, which drives the first fan 3 to rotate. This process is represented as kinetic energy being converted into wind energy.
[0016] Experiment 3: Kinetic energy is converted into electrical energy. Based on Experiment 2, the first fan 3 rotates and drives the generator motor 4 to rotate, generating electrical energy. This process is represented as converting kinetic energy into electrical energy.
[0017] Experiment 4: Converting electrical energy into light energy. Building on Experiment 4, the current generated by generator motor 4 causes bulb 5 to light up. This process is represented as converting electrical energy into light energy.
[0018] Experiment 5: Chemical energy is converted into kinetic energy. Baking soda is first put into the pressurized spray bottle 1 and white vinegar is put into the storage bottle 6. Then, the switch on the second conduit 16 is turned on, and the storage bottle 6 is squeezed to squeeze the white vinegar into the pressurized spray bottle 1 through the second conduit 16. Then, the switch on the second conduit 16 is turned off, and the spray bottle is shaken continuously. Through the transparent bottle body 11, it can be observed that the white vinegar and baking soda are reacting violently. Then, the third conduit 17 is turned on, and the gas produced by the reaction of white vinegar and baking soda is blown out through the third conduit 17, which drives the second fan 7 to rotate. This process shows that the chemical energy produced by the violent reaction of white vinegar and baking soda is converted into kinetic energy.
[0019] The energy conversion demonstration device can complete all the experiments in one class period, and it connects multiple types of energy to explore their continuous conversion process. The data obtained is accurate, the error is reduced, the experimental time is shortened, and the effect is obvious.
[0020] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present invention should be covered within the scope of protection of the present invention.
