Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of light demonstration, and more specifically to a light propagation along a straight line demonstration device. Background Art
[0002] Light propagates in a straight line in the same homogeneous medium, which is an important foundation of geometric optics and is usually referred to as the rectilinear propagation of light. Using this principle, we can solve many problems related to imaging. For example, pinhole imaging is a typical application of light propagating in a straight line. The image it forms is an inverted real image, and the shape of this image has nothing to do with the shape of the hole.
[0003] Traditionally, when demonstrating the propagation of light in a straight line, a pinhole imaging experiment is used to verify it. However, due to the brightness of the light in the room, the phenomenon demonstrated by the teacher is not clear enough for the students to see. If we use laser light to demonstrate directly, we cannot directly see the propagation path of light from the vertical plane of the light path. Also, because laser light cannot be viewed directly, it will cause damage to the eyes if it is directly illuminated from the front. Therefore, the light path is not easy to see, and the knowledge that light propagates in a straight line cannot be intuitively displayed. For this reason, it needs to be modified and optimized. Utility Model Content
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a light propagation demonstrator in a straight line, which has the advantage of being easy to observe.
[0005] To achieve the above object, the utility model provides the following technical solution: a light propagation demonstration device in a straight line, comprising a housing 1, a touch switch, and a handle, wherein the touch switch is fixedly arranged on the side of the housing 1, and the handle is fixedly arranged on the top of the housing 1;
[0006] It includes a base fixedly arranged inside the shell one, an ultrasonic oscillation module is fixedly installed on the top of the base, a fan is fixedly installed on the top of the base, a float is fixedly installed on the top of the base, a smoke outlet cover is movably installed on the top of the shell one, a mist outlet is opened on the top of the smoke outlet cover, a support plate is fixedly installed inside the mist outlet, a limiting block is fixedly installed above the support plate, a shell two is movably installed above the support plate, a battery box is fixedly installed on one side inside the shell two, a battery is fixedly installed inside the battery box, a laser module is fixedly installed on the top of the shell two, and a switch is fixedly installed on the side of the shell two.
[0007] As a preferred technical solution of the utility model, it also includes a connecting line fixedly arranged on one side of the shell, and the connecting line is located opposite to the touch switch.
[0008] As a preferred technical solution of the utility model, a water storage tank is provided inside the housing 1, and the water storage tank is located above the ultrasonic oscillation module.
[0009] As a preferred technical solution of the present utility model, the number of the ultrasonic vibration modules is four, and they are evenly fixed above the base.
[0010] As a preferred technical solution of the utility model, there are two fans, which are evenly and fixedly arranged above the base.
[0011] As a preferred technical solution of the utility model, the battery box and the laser module are connected by wires, and the battery box and the battery are movably connected.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0013] The utility model removes the smoke cover and directly adds water to the inside of the water tank. After adding water, the smoke cover is covered and connected to a 220 volt, 50 Hz power supply through a connecting line. Then, by turning on the laser light switch and then turning on the touch switch of the smoke generator, a light path can be seen after two seconds. When the device is no longer used, the power switch is directly turned off, the power is disconnected, and the laser light switch is turned off. Compared with the traditional device, the device is a perfect combination of the laser light and the smoke generator. The smoke cover of the smoke generator is cleverly designed, and the smoke generated is a hollow column. The laser light is embedded in the center of the smoke cover, and the emitted laser beam is also in the center of the hollow smoke column, so that the generated light path can be displayed 360 degrees without dead angles. The principle is that the laser light emits a laser beam, and the beam is surrounded by the generated hollow smoke column. We watch from the vertical plane of the beam. The light encounters smoke and is reflected and refracted, causing changes in light and dark, and we can see the light propagating in a straight line. Because laser is pure light with only a single frequency, it has color and is more easily detected by the human eye. This device can present the Tyndall effect in the classroom, and create a local colloidal environment in the room through a smoke generator, making the light propagation in a straight line more intuitive and visible to the naked eye, reducing the difficulty of experimental operation.

[0021] like Figures 1 to 5 As shown, the utility model provides a light propagation demonstration device in a straight line, comprising a housing 1, a touch switch 2, and a handle 3, wherein the touch switch 2 is fixedly arranged on the side of the housing 1, and the handle 3 is fixedly arranged on the top of the housing 1;
[0022] The utility model comprises a base 17 fixedly arranged inside the shell 1, an ultrasonic oscillation module 7 is fixedly installed on the top of the base 17, a fan 5 is fixedly installed on the top of the base 17, a float 6 is fixedly installed on the top of the base 17, a smoke outlet cover 18 is movably installed on the top of the shell 1, a mist outlet 10 is provided on the top of the smoke outlet cover 18, a support plate 9 is fixedly installed inside the mist outlet 10, a limiting block 11 is fixedly installed above the support plate 9, a shell 2 12 is movably installed above the support plate 9, a battery box 13 is fixedly installed on one side inside the shell 2 12, a battery 14 is fixedly installed inside the battery box 13, a laser module 15 is fixedly installed on the top of the shell 2 12, and a switch 16 is fixedly installed on the side of the shell 2 12.
[0023] When the staff uses the device, first place the demonstrator horizontally in a suitable place, remove the smoke cover 18, and add water directly to the water storage tank 8, but do not exceed the "highest water level line". Inject pure water or tap water, and the water temperature should not exceed 40 degrees. After adding water, cover the smoke cover 18 and connect it to a 220-volt, 50-hertz power supply through the connecting line 4. Then turn on the switch 16 and then turn on the touch switch 2.

[0024] By removing the smoke cover 18, add water directly to the water tank 8. After adding water, cover the smoke cover 18 and connect the 220 volt, 50 Hz power supply through the connecting line 4. Then turn on the switch 16 and the touch switch 2. After two seconds, you can see a light path. When the device is no longer used, disconnect the connecting line 4 from the power supply and then turn off the switch 16. Compared with traditional devices, we cannot directly see the light propagation path from the vertical plane of the light path when simply using the laser light beam to study the light propagation path. Because the laser light cannot be viewed directly, it will cause damage to the eyes when it is directly illuminated from the front. Therefore, the light path is not easy to be seen. After optimization, the device has the following characteristics: the laser light emits a laser beam, and the beam is surrounded by the hollow smoke column. When we watch from the vertical plane of the beam, the light is reflected and refracted when it encounters smoke, causing changes in light and dark, and we can see the light propagating in a straight line. Because the laser is pure light with only a single frequency, it is colored, and it is easier to be detected by the human eye through the laser. The device can present the Tyndall effect in the classroom. By using a smoke generator to create a local colloidal environment indoors, the propagation of light in a straight line can be more intuitive and visible to the naked eye, thus reducing the difficulty of experimental operation.
[0025] The housing 1 further includes a connecting line 4 fixedly arranged on one side of the housing 1 , and the connecting line 4 is located opposite to the touch switch 2 .
[0026] A 220 volt, 50 Hz power source can be connected to the interior of the device via the connecting line 4, thereby powering the device.
[0027] A water storage tank 8 is provided inside the housing 1 , and the water storage tank 8 is located above the ultrasonic oscillation module 7 .
[0028] Pure water can be added into the interior of the device through the water storage tank 8, thereby increasing the content of pure water inside the device.
[0029] There are four ultrasonic vibration modules 7 , which are evenly and fixedly disposed above the base 17 .
[0030] Increasing the amount of water mist produced makes the demonstration effect better after spraying, thereby improving the working efficiency of the device.
[0031] There are two fans 5 , which are evenly and fixedly disposed above the base 17 .
[0032] After the water mist is generated, the rising speed of the water mist can be increased, thereby improving the working efficiency of the device.
[0033] The smoke outlet of the smoke outlet cover 18 is designed to be annular.
[0034] This will make the smoke emitted in a hollow column shape with the light beam in the center, ensuring 360-degree viewing without blind spots.
[0035] The battery box 13 and the laser module 15 are connected via wires, and the battery box 13 and the battery 14 are movably connected.
[0036] When the battery 14 is out of power, the battery 14 can be replaced, thereby improving the working efficiency of the device.
[0037] The working principle and use process of this utility model:
[0038] When the staff uses the device, first place the demonstrator horizontally in a suitable place, remove the smoke cover 18, and add water directly to the water storage tank 8, but do not exceed the "highest water level line". Inject pure water or tap water, and the water temperature should not exceed 40 degrees. After adding water, cover the smoke cover 18 and connect it to a 220-volt, 50-hertz power supply through the connecting line 4. Then turn on the switch 16 and then turn on the touch switch 2. After two seconds, you can see a light path. When the device is no longer in use, directly disconnect the connecting line 4 from the power supply, and then directly turn off the switch 16.
