[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. 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 implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.
[0025] Explanation of scientific principles:
[0026] 1. Birefringence refers to the phenomenon that a single incident light ray produces two refracted light rays.
[0027] 2. Iceland spar, with the chemical composition of CaCO 3 , is colorless, transparent and pure calcite. Due to its special physical properties, it is called a special non-metallic mineral. It was first discovered in Iceland, so it is called "Iceland spar". It has the highest birefringence and polarization properties among white transparent crystal minerals, that is, through it, an object can be seen as a double image.
[0028] As Figure 1 - Figure 2 shown, the present utility model provides a scientific experiment device for expressing the principle of mineral birefringence, including a device body 1, an Iceland spar mineral plate 2 and a light source mechanism arranged in the device body 1. The device body 1 is in a cube structure. The device body 1 has a first experimental side 11 and a second experimental side 12 arranged vertically, and a first observation side 13 and a second observation side 14 arranged vertically and transparently. Both the first experimental side 11 and the second experimental side 12 are provided with opaque experimental areas; the light source mechanism includes a bidirectional red light source 3 and a control switch 4. The bidirectional red light source 3 can emit light rays towards the first experimental side 11 and the second experimental side 12 respectively. The Iceland spar mineral plate 2 is detachably installed between the second experimental side 12 and the bidirectional red light source 3. The control switch 4 is arranged on the top surface of the device body 1 and is electrically connected to the bidirectional red light source 3.
[0029] This utility model adopts a bidirectional red light source 3, using red light as the light source, avoiding the potential safety risks that may be brought by using high-intensity light sources, and effectively protecting the eyes of students. Moreover, the bidirectional red light source 3 enables the light to be emitted towards the first experimental side 11 and the second experimental side 12 respectively, facilitating the observation of the birefringence phenomenon. Students can easily control the opening and closing of the bidirectional red light source 3 through the control switch 4, without complex operation steps and without the need for manual instructions, which is convenient for students' autonomous learning and practice.
[0030] Iceland spar birefringence, as a unique optical phenomenon, demonstrates the unique physical properties of Iceland spar. Through the scientific experiment device provided by this utility model, students can operate it by themselves, more directly feel the principle of mineral birefringence, and thus deepen their understanding of the microscopic structure and optical properties of substances.
[0031] It should be noted that the bidirectional red light source 3 and the control switch 4 adopt existing technologies and will not be elaborated here.
[0032] As an optional implementation manner, the side length of the device body 1 is 10 cm.
[0033] With such a setting, students can clearly observe the birefringence phenomenon on the second experimental side 12 while it is convenient for handling and carrying.
[0034] As an optional implementation manner, black cardboard is laid on the experimental areas of the first experimental side 11 and the second experimental side 12.
[0035] Furthermore, a first black cardboard 111 is laid on the experimental area of the first experimental side 11, and a second black cardboard 121 is laid on the experimental area of the second experimental side 12. The first black cardboard 111 and the second black cardboard 121 are circular.
[0036] The bidirectional red light source 3 is adaptively arranged with the first black cardboard 111 and the second black cardboard 121.
[0037] The first black cardboard 111 and the second black cardboard 121 can absorb most of the light, reduce the interference of stray light, and thus enhance the observation effect of the experiment, that is, the light emitted by the bidirectional red light source 3 can form a clear and obvious single red dot on the first black cardboard 111 and a clear and obvious double red dots on the second black cardboard 121.
[0038] When the bidirectional red light source 3 irradiates on the first experimental side 11, since no Iceland spar mineral plate 2 is installed on the first experimental side 11, the light emitted by the bidirectional red light source 3 directly irradiates on the first black cardboard 111, forming a single, bright red dot.
[0039] When the bidirectional red light source 3 irradiates the second experimental side 12, since the Iceland spar mineral plate 2 is installed in front of the second experimental side 12, the light emitted by the bidirectional red light source 3 will undergo double refraction when passing through the Iceland spar mineral plate 2, and the light is decomposed into two beams, which propagate along different directions respectively. Therefore, two red dots will be displayed on the second black cardboard 121. This visually demonstrates the double refraction characteristics of Iceland spar and helps students understand the double refraction principle.
[0040] As an alternative implementation, a slot 15 is provided on the inner wall of the device body 1, and the Iceland spar mineral plate 2 is detachably connected to the slot 15.
[0041] Furthermore, the slots 15 are oppositely arranged on the first observation side 13 and the first experimental side 11 and extend in the vertical direction, so that the Iceland spar mineral plate 2 can be inserted and fixed into the slots 15 from top to bottom, and the position of the slots 15 will not interfere with the light irradiating the first black cardboard 111. Among them, the slot 15 is a prior art and can be set according to the usage requirements, and will not be elaborated here.
[0042] The Iceland spar mineral plate 2 is designed to be detachable, which is convenient for students to take out for touch observation, increasing the interest of the experiment and enabling students to more intuitively feel the physical properties of Iceland spar, such as hardness, luster, etc. At the same time, after taking out the Iceland spar mineral plate 2, since there is no double refraction medium, the light forms a single red dot on the second experimental side 12, and the double refraction principle can be further understood through comparison.
[0043] As an alternative implementation, the Iceland spar mineral plate 2 is arranged parallel to the second observation side 14, so that when the light undergoes double refraction after passing through the Iceland spar mineral plate 2, the two refracted lights can be clearly projected onto the second observation side 14 to form double red dots.
[0044] As an alternative implementation, the thickness of the Iceland spar mineral plate 2 is 1 cm.
[0045] The Iceland spar mineral plate 2 set in this way can provide a clear and obvious double refraction effect. At the same time, it is convenient for students to take out the Iceland spar mineral plate 2 for touch observation, and more intuitively feel the physical properties of Iceland spar, such as hardness, luster, etc., enhancing the experience and interest of the experiment.
[0046] As an alternative implementation, it further includes a voice explanation mechanism, which includes a speaker, an explanation button and a control chip. The speaker and the explanation button are arranged on any side or the top surface of the device body 1 and are respectively electrically connected to the control chip.
[0047] Furthermore, the speaker and the explanation button can be arranged on the top surface of the device body 1 and will not interfere with the experimental operation.
[0048] When the student presses the explanation button, the loudspeaker is triggered to play the pre-recorded voice explanation content, which helps the student better understand and master the experimental content and improve the effect of experimental teaching. The voice explanation content includes the introduction of the scientific experimental device, the explanation of the birefringence principle, the description of the experimental operation steps, etc., which can be specifically designed according to the usage requirements. Among them, the specific circuit connection relationship between the loudspeaker and the explanation button and the control chip is the prior art and will not be elaborated here.
[0049] As an optional implementation manner, a two-dimensional code 5 is provided on the outer wall surface of any side or the top surface of the device body 1. The mobile terminal scans the two-dimensional code 5 to obtain information about the birefringence principle and the scientific experimental device, which helps the student better understand and master the experimental content and improve the effect of experimental teaching. Among them, the two-dimensional code 5 adopts the prior art and will not be elaborated here.
