Description

Technical Field

[0001] This utility model relates to a visible optical experimental device with ultrasonic atomization optical path, belonging to the field of optical experimental tools. Background Technology

[0002] As a fundamental and comprehensive course for cultivating students' scientific thinking and practical inquiry abilities, elementary school science has always included experiments on the properties of light. Textbooks from various editions, including those from Jiangsu Education Press, Shanghai Science and Technology Press, and Hunan Education Press, have consistently featured experiments on light, such as the rectilinear propagation of light, reflection, and refraction.

[0003] In our front-line experimental teaching, we have found a common teaching difficulty in the above studies on the properties and laws of light, namely the problem that the light path is invisible.

[0004] Looking at various textbook versions and the solutions adopted by front-line teachers, they can be summarized into the following categories: 1. Creating smoke in the air by burning mosquito coils, making the light path visible. 2. Using a high-powered laser pointer to make the light path visible in the air. 3. Using a beam splitter to make the light form a straight line on a certain plane, demonstrating the propagation path of the light.

[0005] However, all of the above methods have certain shortcomings in teaching practice, and some even contain scientific errors. Specifically, the method of making the light path visible by burning incense is cumbersome because it requires burning mosquito coils or other incense, and also poses certain fire safety hazards. More importantly, the smoke produced by burning incense and mosquito coils contains certain toxic components, and students inevitably inhale this smoke during experiments, causing some health harm.

[0006] Secondly, if the smoke is too dense, the light path will not be visible; if the smoke is too thin, it will cause the light path to be discontinuous and appear as a dotted line.

[0007] Meanwhile, existing high-power laser pointers make the light path visible in the air. If students use them improperly in experimental teaching, they can easily damage their eyesight, posing a great danger.

[0008] Furthermore, the experimental method of using a beam splitter to make a laser beam form a straight line on a plane is actually an illusion of light traveling in a straight line. The essence is that the light travels to the surface of the object in a straight line, not that the light travels along such a visible straight line. Strictly speaking, this is a scientific error.

[0009] Therefore, there is a need for an optical experimental device that can make the light path visible, which will help students deepen their understanding of the rectilinear propagation, refraction, and reflection of light. Summary of the Invention

[0010] In view of this, the purpose of this utility model is to provide an ultrasonic atomization optical path visible optical experimental device, which can realize the optical path is visible, which is conducive to deepening students' understanding of the rectilinear propagation, refraction and reflection of light; it can overcome the shortcomings of the existing technology.

[0011] The objective of this utility model is achieved through the following technical solution: This utility model discloses an ultrasonic atomization optical path visible optics experimental device, which includes an open transparent box and a handheld laser pointer. An ultrasonic atomization component for filling the transparent box with water mist is installed on the side of the transparent box, and an optical auxiliary device for light refraction, reflection or dispersion is placed inside the transparent box.

[0012] The ultrasonic atomizing assembly described above includes a power supply, a circuit board connected to the power supply, an atomizing head for generating atomization, and a sponge inserted into the atomizing head. The circuit board is connected to the atomizing head via wires, and a movable connecting device for the atomizing head is provided along the transparent housing.

[0013] The aforementioned movable connection device includes a clip provided along the upper edge of the transparent housing, and a "C"-shaped bracket on which an atomizing head is fixed.

[0014] The aforementioned optical auxiliary device is a combination of one or more of water, a prism, or a plane mirror, wherein the prism has a base on its lower side and the plane mirror is movably placed at the bottom of the transparent box.

[0015] As mentioned above, a black back panel is provided on the back side of the transparent box.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses an ultrasonic atomizing component to atomize the space inside a transparent box. Then, a handheld laser pointer is used to illuminate the transparent box, and the light path is revealed through atomization. At the same time, experiments on light refraction, reflection, or dispersion are conducted using an optical auxiliary device.

[0017] 2. By soaking a sponge in water and inserting it into the atomizing head, and then turning on the switch on the circuit board, fog will be filled into the transparent box. This allows you to shine a laser pointer into the fogged transparent box to reveal the light path. At the same time, the movable connecting device facilitates the installation and removal of the atomizing head, making it easy to replace the atomizing head or place it in a specific position within the transparent box to fill a certain area with high-density fog for clearer observation of the light path in that area.

[0018] The movable connection device includes a clip provided along the upper edge of the transparent box, and a "C"-shaped bracket for fixing the atomizing head on the clip. This allows for flexible installation in a certain area of ​​the transparent box via the clip, while the "C"-shaped bracket facilitates the mounting of the atomizing head.

[0019] 3. The optical auxiliary device is a combination of one or more of the following: water, a prism, or a plane mirror. The prism has a base on its lower side, and the plane mirror is movably placed at the bottom of the transparent box. Water is placed inside the transparent box, positioned to the middle, with mist above the water. A handheld laser pointer can then be used to illuminate the water. By observing the changes in the light path in the mist and water, the refraction of light in water can be directly observed. Simultaneously, the prism facilitates the observation of the visible light portion after dispersion, while the plane mirror at the bottom of the transparent box facilitates the observation of light reflection. Water, prisms, and plane mirrors can be placed individually in the transparent box or in combination. For example, the combination of water and a plane mirror allows observation of both refraction and reflection of light. Depending on the specific light combination experiment, other combinations may be used, such as water and a prism, a prism and a plane mirror, or water, a prism, and a plane mirror.

[0020] 4. A black backplate is provided on the back of the transparent box, so that the light path can be better observed through the black backplate when observing the light path.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0029] like Figures 1-5 As shown, this utility model discloses an ultrasonic atomization optical path visible optics experimental device, which includes a transparent box 1 without a cover and a handheld laser light 2. An ultrasonic atomization component 3 for atomizing the interior of the transparent box 1 is movably connected to the upper edge of the transparent box 1. Optical auxiliary devices for light refraction, reflection or dispersion can be selectively placed inside the transparent box 1. With this structure, the space inside the transparent box 1 can be atomized by the ultrasonic atomization component 3, and then the handheld laser light 2 can be used to irradiate the transparent box 1 to reveal the optical path through atomization. At the same time, experiments on light refraction, reflection or dispersion can be performed by the optical auxiliary devices.

[0030] Furthermore, the ultrasonic atomizing component 3 includes a power supply 4, a circuit board 5 connected to the power supply 4, an atomizing head 6 for generating atomization, and a sponge 7 inserted into the atomizing head 6. The circuit board 5 is connected to the atomizing head 6 via wires. A movable connecting device for the atomizing head 6 is provided along the upper edge of the transparent housing 1. In use, by soaking the sponge in water and then inserting it into the atomizing head 6, and activating the switch on the circuit board 5, mist can be filled into the transparent housing 1. This allows the light path to be displayed by illuminating the transparent housing 1 after it has been filled with mist using a handheld laser light 2. At the same time, the movable connecting device facilitates the installation and removal of the atomizing head 6, making it convenient to replace the atomizing head 6 or to place the movable atomizing head 6 at a certain position in the transparent housing 1 to fill a certain area with high-density mist, so as to observe the light path of a certain area more clearly. Specifically, the movable connection device includes a clip 8 provided along the upper edge of the transparent box 1, and a "C"-shaped bracket 9 for the atomizing head 6 fixed on the clip 8. In this way, the clip 8 can be flexibly installed in a certain area of ​​the transparent box 1, and the "C"-shaped bracket 9 can facilitate the mounting of the atomizing head 6.

[0031] Furthermore, the optical auxiliary device is a combination of one or more of water, a prism 10, or a plane mirror 11. The prism 10 has a base on its lower side, and the plane mirror 11 is movably placed at the bottom of the transparent box 1. By placing water inside the transparent box 1, with the water level reaching the middle of the box and mist above it, a handheld laser pointer 2 can be used to illuminate the water. By observing the changes in the light path in the mist and in the water, the refraction effect of light in water can be directly observed. Simultaneously, the prism 10 facilitates the observation of the visible light portion after dispersion, while the plane mirror 11 at the bottom of the transparent box 1 facilitates the observation of light reflection. Water, prism 10, and plane mirror 11 can be placed individually in the transparent box 1 or in combination. For example, the combination of water and plane mirror 11 allows observation of both light refraction and light reflection. Depending on the light combination experiment, such as the combination of water and prism 10, the combination of prism 10 and plane mirror 11, or the combination of water, prism 10, and plane mirror 11, the experiment can be conducted.

[0032] Furthermore, a black backplate is provided on the back side of the transparent box 1, so that the optical path can be better observed through the black backplate when observing the optical path.

[0033] This device successfully overcomes the teaching challenge of making light paths invisible by using an ultrasonic atomization module to create a water mist of suitable concentration in the air. The experimental setup uses water as the experimental material, avoiding the potential for injury associated with high-powered laser pointers and overcoming the health hazards of using harmful gases such as mosquito coil smoke to reveal the light path. It also corrects the scientific error of using a beam splitter to make the light path visible. The compact and flexible nature of this device allows students to verify the straight-line characteristics of any segment of the light path, overcoming the limitation of other experimental setups that can only verify the straight-line propagation of a specific segment of the light path. This makes student experimental investigations more comprehensive and their conceptual construction more rigorous. The device also achieves visible light paths in experiments involving light dispersion and light recombination.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to restrict the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments without departing from the technical solution of the present utility model and based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
