Description

Technical Field

[0001] The utility model belongs to the field of teaching demonstrations, and specifically relates to a device for visually demonstrating energy conversion. Background Art

[0002] Teaching demonstration refers to an activity in the process of education or training, where teachers or lecturers use various tools, materials, and methods to show, explain, and illustrate concepts, processes, skills, or theories to students. Its purpose is to enhance students' understanding, stimulate their learning interest, and promote the absorption and application of knowledge through intuitive and interactive means.

[0003] The existing Chinese patent CN107301809A discloses a teaching energy conversion demonstration device. The demonstration device includes: a transparent container for containing liquid, the transparent container including a first outlet; a blade assembly including rotatable blades, the rotatable blades being arranged at a position corresponding to the first outlet; a power generation assembly connected to the blade assembly; a light condensing assembly for converging external sunlight into a first light beam and irradiating the first light beam onto the liquid in the transparent container; when the liquid is heated to boiling and becomes hot steam under the irradiation of the first light beam, the hot steam escapes from the first outlet, causing the gas around the first outlet to expand and move upward, thereby driving the rotatable blades to rotate, and when the rotatable blades rotate, they drive the power generation assembly to generate electricity. In the above manner, the demonstration device provided by the present invention can visually reflect energy conversion.

[0004] The above demonstration device needs to rely on sunlight to be used, which has certain limitations. At the same time, the energy conversion method of the existing demonstration device is relatively single and cannot cover multiple energy conversions. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides a device for visually demonstrating energy conversion to solve the problems such as the relatively single energy conversion method of the demonstration device in the prior art and the inability to cover multiple energy conversions.

[0006] A device for visually demonstrating energy conversion includes: a mounting frame, a pressure sprayer assembly, a fan, a generator, and a light bulb mounted on the mounting frame, the generator and the light bulb being electrically connected; the generator is arranged at the rear side of the fan, the pressure sprayer assembly can drive the fan to rotate, the rotation of the fan can drive the generator to work, and the work of the generator can drive the light bulb to work.

[0007] Preferably, the pressure sprayer assembly includes a pressure sprayer, and a digital display thermometer is further arranged on the pressure sprayer, and the digital display thermometer can detect the temperature inside the pressure sprayer.

[0008] Preferably, it further includes a voltage stabilizer, which is electrically connected to the mobile phone and can be electrically connected to the generator.

[0009] Compared with the prior art, the utility model has the following beneficial effects: Through actual operation and observation, the device can intuitively display the conversion process between internal energy, mechanical energy, electrical energy and light energy. Students or observers can clearly see that when pressing the pneumatic sprayer, the internal energy is converted into mechanical energy, and then the rotation of the fan drives the generator to work, converting mechanical energy into electrical energy, and finally making the light bulb light up, realizing the conversion of electrical energy into light energy.

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0014] As Figures 1 to 2 shown:

[0015] Embodiment 1: The present utility model provides an intuitive demonstration device for energy conversion, including: a mounting bracket 1, a pneumatic sprayer assembly 2, a fan 3, a generator and a light bulb 4 mounted on the mounting bracket 1, and the generator and the light bulb 4 are electrically connected; the generator is arranged at the rear side of the fan 3, the pneumatic sprayer assembly 2 can drive the fan 3 to rotate, the rotation of the fan 3 can drive the generator to work, and the work of the generator can drive the light bulb 4 to work;

[0016] Among them, place the entire device on a horizontal tabletop. By pressing multiple times, the gas inside the pneumatic sprayer assembly 2 is compressed. Open the valve of the pneumatic sprayer assembly 2 to make the compressed gas spray out to the outside. The sprayed gas will drive the fan 3 to rotate, thereby demonstrating the process of converting internal energy into mechanical energy. The rotation of the fan 3 will cause the generator to work, and the work of the generator will cause the light bulb 4 to light up, thereby demonstrating the process of converting mechanical energy into electrical energy and light energy.

[0017] Specifically, the air pressure sprayer assembly 2 includes an air pressure sprayer 21, and a digital display thermometer 22 is further arranged on the air pressure sprayer 21. The digital display thermometer 22 can detect the temperature inside the air pressure sprayer 21.

[0018] As can be seen from the above, when pumping air into the air pressure sprayer 21 about 20 times, it can be observed that the reading of the digital display thermometer 22 increases significantly, that is, the mechanical energy of the piston is converted into the internal energy of the gas in the pot. When opening the valve of the air pressure sprayer 21 to release gas, the released gas drives the fan to rotate, and at the same time, the reading of the digital display thermometer 22 decreases significantly, that is, the internal energy of the gas in the pot is converted into the mechanical energy of the fan. The rotation of the fan makes the generator work and thus makes the light bulb emit light, that is, the mechanical energy is converted into electrical energy, and the electrical energy is further converted into light energy.

[0019] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that it further includes a voltage stabilizer. The voltage stabilizer is electrically connected to the mobile phone and can be electrically connected to the generator.

[0020] As can be seen from the above, when electrically connecting the voltage stabilizer and the generator and pumping air into the air pressure sprayer 21 about 40 times, at this time, the reading of the digital display thermometer 22 increases. When opening the valve of the air pressure sprayer 21 to release gas, the fan 3 rotates and the mobile phone shows charging. At this time, the mechanical energy of the fan 3 is converted into electrical energy and then into the chemical energy of the mobile phone.
