The shaping component includes at least two shaping frames and a handle for driving the shaping frame to rotate around the plumb line. The shaping frame is provided with a shaping hole that passes through from top to bottom. The shaping hole of the shaping frame and the movement path of the transparent demonstration station intersect at the top opening of the first heating water tank.

[0009] As a further solution of the present invention: a second atomizer and a turbulent fan are further provided inside the first heating water tank.

[0010] As a further solution of the present invention: an illumination light source is further provided below the turntable on the movement path of the transparent demonstration station.

[0014] As a further solution of the present invention, the polarizer observation mirror can swing around a vertical rotation axis distributed beside the plate-type refrigerator.

[0015] As a further solution of the present invention: the polarizer viewing mirrors are provided in at least two groups.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The water in the first water tank is atomized into white gas through the first atomizer, replacing the invisible water vapor with white gas, making the demonstration safer. In addition, a resiliently adjustable pressure plate is provided at the top opening of the first water tank. By pressing the pressure plate, the audience can generate pressure changes in the first water tank, thereby forcing the atomized white gas in the first water tank to rise and be discharged through the through hole. As the audience presses the pressure plate back and forth, the through hole will continuously eject white gas, making it highly ornamental and interesting. The interactive nature of the demonstration device is not only suitable for classroom teaching, but also for autonomous interactive demonstrations in exhibition halls such as science and technology museums.

[0018] 2. The outer periphery of the pressure plate forms a sealing fit with the first water tank through a silicone plate. Compared with the sliding sealing fit between the outer periphery of the pressure plate and the first water tank, it not only has a better sealing effect, but also effectively reduces the resistance during the lifting and lowering process of the pressure plate.

[0019] 3. The first heating water tank is heated using a heating rod, generating a high-temperature airflow. At this point, the handle is turned to move one of the sculpting frames directly above the first heating water tank. Simultaneously, the turntable is rotated to move one of the transparent demonstration stations directly above the first heating water tank. The hot airflow generated by the first heating water tank then passes through the patterned holes in the sculpting frame and condenses at the transparent demonstration station to form liquid water with a specific pattern. Subsequently, the turntable is rotated to switch the transparent demonstration station above the first heating water tank, and the handle is then turned to switch the sculpting frame above the first heating water tank. This allows liquid water to condense at the transparent demonstration station to form different patterns, effectively enhancing the interactivity and fun of the liquid water demonstration.

[0020] 4. A second atomizer and a turbulent fan are also provided inside the first heating water tank. The heated water is atomized by the second atomizer, and the atomized water mist is driven upward by the turbulent fan, making it easier to condense at the transparent demonstration station, which not only improves the demonstration effect, but also reduces the heating temperature required in the first heating water tank.

[0021] 5. An illumination light source is provided below the turntable on the movement path of the transparent demonstration station, so that the audience can better observe the specific pattern of liquid water formed on the transparent demonstration station.

[0022] 6. A drying component is provided below the turntable on the movement path of the transparent demonstration station, which is used to remove liquid water from the transparent demonstration station after the demonstration so that the transparent demonstration station can be put into the next demonstration operation more quickly.

[0023] 7. A high-temperature airflow is generated through the second heating water tank, and the condensation of liquid water is demonstrated on the condensation barrel above the turntable. This allows more viewers to observe the condensation process of liquid water based on the demonstration of the condensation process on the turntable.

[0024] 8. In the solid-state demonstration component, after liquid water condenses into thin ice, the shape of the thin ice can be observed through the polarizing observation mirror set just above the refrigeration plate surface, which facilitates further observation and understanding of the internal shape of solid water.

[0025] 9. By rotating the polarizing film observation mirror, the morphological differences of thin ice in different positions can be observed, which helps the audience further understand the differences in the internal morphology of solid water. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] For ease of understanding, the specific structure and working mode of the present invention are further described below with reference to the accompanying drawings:

[0036] The specific structure of the utility model refers to Figure 1-7 As shown, its main structure includes a platform 10, on which a gas demonstration component 20, a liquid demonstration component 30 and a solid demonstration component 40 are installed.

[0037] like Figure 2 and Figure 3 As shown, the liquid demonstration assembly 30 includes a first water tank 27 and a first atomizer 26 mounted within the first water tank 27. A resiliently elevating pressure plate 21 is provided at the top opening of the first water tank 27. The outer periphery of the pressure plate 21 is sealed against the first water tank 27, and a through hole 23 is provided in the center of the pressure plate 21 for upward airflow. In this application, the first atomizer 26 atomizes the water in the first water tank 27 into white gas, which replaces invisible water vapor, enhancing the safety of the demonstration. Furthermore, the resiliently elevating pressure plate 21 is provided at the top opening of the first water tank 27. By pressing the pressure plate 21, the audience can generate pressure changes within the first water tank 27, thereby causing the atomized white gas in the first water tank 27 to rise and be discharged through the through hole 23. As the audience reciprocates, the through hole 23 continuously ejects white gas, making the demonstration highly visual and interesting. This also makes the demonstration device interactive, making it suitable not only for classroom teaching but also for autonomous interactive demonstrations in exhibition halls such as science and technology museums.

[0038] On the basis of the above, if Figure 3 As shown, a vertically arranged guide telescopic rod 24 is mounted within the first water tank 27. A return spring 25 is sleeved on the guide telescopic rod 24 to drive the pressure plate 21 upward, ensuring the stability of the lifting motion of the pressure plate 21. Furthermore, the outer periphery of the pressure plate 21 forms a sealed fit with the first water tank 27 via a silicone plate 22. This not only provides a better sealing effect than a sliding seal between the outer periphery of the pressure plate 21 and the first water tank 27, but also effectively reduces resistance during the lifting and lowering of the pressure plate 21.

[0039] like Figure 4 and Figure 5As shown, the liquid demonstration assembly 30 includes a turntable 31 mounted on the surface of the table 10. The turntable 31 can rotate about its own vertical axis, and a number of transparent demonstration stations 311 are eccentrically arranged on the surface of the turntable 31. Below the turntable 31, a shaping assembly 33 and a first heating water tank 34 are arranged in sequence. The first heating water tank 34 contains a heating rod. The shaping assembly 33 includes at least two shaping frames 332 and a handle 331 for driving the shaping frames 332 to rotate about the vertical line. The shaping frames 332 are provided with shaping holes extending vertically. The shaping holes of the shaping frames 332 and the movement paths of the transparent demonstration stations 311 intersect at the top opening of the first heating water tank 34. In this application, the shaping frames 332 are frame structures with shaping holes formed in a specific pattern in the middle. Specifically, the specific pattern can be a five-pointed star pattern, a triangle pattern, or an animal pattern. In actual implementation, the shaping patterns of different shaping frames 332 are preferably set to be different. During use, the first heating water tank 34 is heated by the heating rod, causing it to generate a high-temperature airflow. At this time, the handle 331 is turned to move one of the shaping frames 332 to the position directly above the first heating water tank 34. Simultaneously, the turntable 31 is turned to rotate one of the transparent demonstration stations 311 of the turntable 31 to the position directly above the first heating water tank 34. At this time, the hot airflow generated by the first heating water tank 34 passes through the shaping holes with a specific pattern in the shaping frame 332 and condenses to form liquid water with a specific pattern at the transparent demonstration station 311. Thereafter, the turntable 31 is turned to switch the transparent demonstration station 311 located above the first heating water tank 34. The handle 331 is then turned to switch the shaping frame 332 located above the first heating water tank 34. Liquid water with different patterns can be condensed at the transparent demonstration station 311, effectively enhancing the interactivity and fun of the liquid water demonstration process. In the liquid demonstration component 30 of the present application, the first heating water tank 34 is located inside the platform 10. The heated hot air flow will cool down and condense at the transparent demonstration station 311 of the turntable 31, which has higher demonstration safety.

[0040] On the basis of the above, if Figure 5 As shown, a second atomizer 341 and a turbulent fan 342 are also provided inside the first heating water tank 34. The heated water is atomized by the second atomizer 341, and the atomized water mist is driven to rise by the turbulent fan 342, making it easier to condense at the transparent demonstration station 311, which not only improves the demonstration effect, but also reduces the heating temperature required in the first heating water tank 34.

[0041] On the basis of the above, if Figure 5As shown, an illumination light source and a drying component 36 are further provided below the turntable 31 on the movement path of the transparent demonstration station 311. The provision of the illumination light source facilitates the audience to better observe the liquid water of the specific pattern formed on the transparent demonstration station 311. The drying component 36 is used to remove the liquid water from the transparent demonstration station 311 after the demonstration, so that the transparent demonstration station 311 can be put into the next demonstration operation more quickly. Specifically, the drying component 36 includes a drying fan and / or a scraper, which increases the air flow rate by the drying fan, thereby increasing the evaporation rate of the liquid water; and / or physically scrapes off the liquid water by the scraper, both of which can make the transparent demonstration station 311 dry quickly.

[0042] On the basis of the above, if Figure 5 As shown, a through hole is provided at the center of the turntable 31. A condensation barrel 32 is provided at the center of the upper portion of the turntable 31, passing through the through hole and fixed to the platform 10. A second heating water tank 35 is mounted at the bottom opening of the condensation barrel 32. A heating rod is also mounted in the second heating water tank 35. A high-temperature airflow is generated by the second heating water tank 35, and the condensation of liquid water is demonstrated on the condensation barrel 32. This facilitates more viewers to observe the condensation process of liquid water based on the demonstration of the condensation process of liquid water on the turntable 31.

[0043] like Figure 6 and Figure 7 As shown, the solid-state demonstration assembly 40 includes a second water tank 44 mounted inside the platform 10 and a plate-type cooler 41 mounted on the surface of the platform 10. The cooling plate of the plate-type cooler 41 is arranged parallel to the surface and is used to hold liquid water and condense it into thin ice. A nozzle 43 is connected to the second water tank 44, spraying water onto the cooling plate. After the liquid water condenses into thin ice, the shape of the thin ice can be observed through a polarizing observation mirror 42 located directly above the cooling plate, facilitating further understanding of the internal structure of the solid water.

[0044] On the basis of the above, if Figure 7 As shown, the polarizer observation mirror 42 can swing around the vertical axis distributed beside the plate-type refrigerator 41. By rotating the polarizer observation mirror 42, the morphological differences of thin ice at different positions can be observed, which helps the audience to further understand the differences in the internal morphology of solid water. In addition, Figure 6 As shown, the polarizer viewing mirrors 42 are provided in at least two groups, which can be used for joint observation by multiple persons.

[0045] Of course, it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, but also encompasses the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
