Description

Technical Field

[0001] This utility model relates to the field of scientific demonstration technology, specifically a liquid water demonstration component. Background Technology

[0002] Water exists in three states: gaseous, liquid, and solid.

[0003] Since liquid water is the most common substance in daily life, demonstrations of liquid water primarily focus on its condensation process. Most existing demonstrations of liquid water, such as those described in Chinese Patent Publication No. CN211207719U entitled "Demonstrator of the Three States of Water," use a rain cover to simulate rainfall. This involves placing a transparent cover over the outlet of a high-temperature gas source, and observing the condensation of water vapor in the air on the inner wall of the cover to demonstrate the liquid state of water. Clearly, this demonstration process is rather simplistic and lacks interactivity with the audience, thus requiring further improvement. Utility Model Content

[0004] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a liquid water demonstration component with a reasonable structure and the ability to form a good interaction with the audience.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A liquid water demonstration component includes a turntable mounted on a platform. The turntable is rotatable around its own vertical axis, and several transparent demonstration stations are eccentrically arranged on the turntable surface. Below the turntable, a modeling component and a first heating water tank are arranged in sequence. A heating rod is installed inside the first heating water tank. The modeling component includes at least two modeling frames and a handle for driving the modeling frames to rotate around a vertical line. The modeling frames are provided with vertically penetrating modeling holes. The movement paths of the modeling holes of the modeling frames and the transparent demonstration stations intersect at the top opening of the first heating water tank.

[0007] As a further embodiment of this utility model, the first heating water tank is also equipped with a second atomizer and a turbulence fan.

[0008] As a further improvement of this utility model, a lighting source is also provided below the turntable on the movement path of the transparent demonstration station.

[0009] As a further improvement of this utility model, a drying component is also provided below the turntable on the movement path of the transparent demonstration station.

[0010] As a further embodiment of this invention: the drying assembly includes a drying fan and / or a scraper.

[0011] As a further embodiment of this utility model: a through hole is provided at the center of the turntable, and a condensation tank is provided at the center of the upper part of the turntable, passing through the through hole and fixed to the platform. A second heating water tank is installed at the bottom opening of the condensation tank, and a heating rod is also installed in the second heating water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The first water tank is heated by a heating rod, generating a high-temperature airflow. Turning the handle moves one of the decorative frames directly above the tank. Simultaneously, rotating the turntable moves one of its transparent demonstration positions directly above the tank. The hot airflow from the tank passes through patterned holes in the decorative frames and condenses at the transparent demonstration position, forming specific patterns of liquid water. Rotating the turntable again switches the transparent demonstration position above the tank, and then rotating the handle again switches the decorative frame, resulting in different patterns of liquid water condensing at the demonstration position. This effectively enhances the interactivity and fun of the liquid water demonstration.

[0014] 2. The first heating water tank is also equipped with a second atomizer and a turbulence fan. The heated water is atomized by the second atomizer and the atomized water mist is driven to rise by the turbulence fan, making it easier to condense at the transparent demonstration station. This not only improves the demonstration effect but also reduces the temperature required to be heated in the first heating water tank.

[0015] 3. Lighting sources are installed below the turntable along the movement path of the transparent demonstration station to facilitate better observation of the liquid water forming specific patterns on the transparent demonstration station.

[0016] 4. A drying component is installed below the turntable on the movement path of the transparent demonstration station 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.

[0017] 5. A high-temperature airflow is generated by the second heating water tank, and the condensation of liquid water is demonstrated on the condensation tank above the turntable. This allows more viewers to observe the condensation process of liquid water, building upon the turntable demonstration. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0028] The specific structure of this utility model is as follows: Figure 1 , Figure 4 and Figure 5 As shown, its main structure includes a platform 10 and a liquid demonstration component 30 mounted on the platform 10.

[0029] like Figure 4 and Figure 5As shown, the liquid demonstration component 30 includes a turntable 31 mounted on the tabletop of the platform 10. The turntable 31 can rotate around its own vertical axis, and several transparent demonstration stations 311 are eccentrically arranged on the surface of the turntable 31. Below the turntable 31, a shaping component 33 and a first heating water tank 34 are arranged in sequence, and a heating rod is arranged inside the first heating water tank 34. The shaping component 33 includes at least two shaping frames 332 and a handle 331 for driving the shaping frames 332 to rotate around the vertical line. The shaping frames 332 are provided with vertically penetrating shaping holes, and the movement paths of the shaping holes of the shaping frames 332 and the transparent demonstration stations 311 intersect at the top opening of the first heating water tank 34. In this application, the shaping frame 332 is a frame structure with a specific pattern shaping hole formed in the middle. Specifically, the specific pattern can be a five-pointed star pattern, a triangle pattern, or an animal pattern, etc. In actual implementation, the shaping patterns of different shaping frames 332 are preferably set to be different. In use, the first heating water tank 34 is heated by a heating rod, generating a high-temperature airflow. Then, turning the handle 331 moves one of the decorative frames 332 directly above the first heating water tank 34. Simultaneously, turning the turntable 31 moves one of its transparent demonstration stations 311 directly above the first heating water tank 34. The hot airflow from the first heating water tank 34 passes through the patterned holes in the decorative frame 332 and condenses at the transparent demonstration station 311, forming liquid water with a specific pattern. Subsequently, turning the turntable 31 switches the transparent demonstration station 311 above the first heating water tank 34, and turning the handle 331 again switches the decorative frame 332 above the first heating water tank 34, allowing liquid water to condense into different patterns 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 this application, the first heating water tank 34 is located inside the platform 10. The heated hot air will cool down and condense at the transparent demonstration station 311 of the turntable 31, which has a high level of demonstration safety.

[0030] Based on the above, such as Figure 5 As shown, the first heating water tank 34 is also equipped with a second atomizer 341 and a turbulence fan 342. The heated water is atomized by the second atomizer 341 and the atomized water mist is driven to rise by the turbulence fan 342, making it easier to condense at the transparent demonstration station 311. This not only improves the demonstration effect but also reduces the temperature required to be heated in the first heating water tank 34.

[0031] Based on the above, such as Figure 5As shown, a lighting source and a drying assembly 36 are also provided below the turntable 31 along the movement path of the transparent demonstration station 311. The lighting source allows viewers to better observe the specific patterns of liquid water formed on the transparent demonstration station 311. The drying assembly 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 more quickly. Specifically, the drying assembly 36 includes a drying fan and / or a scraper. The drying fan increases the airflow rate, thereby increasing the evaporation rate of the liquid water; and / or the scraper physically removes the liquid water, both of which enable the transparent demonstration station 311 to dry quickly.

[0032] Based on the above, such as Figure 5 As shown, a through hole is provided at the center of the turntable 31, and a condensation tank 32, which passes through the through hole and is fixed to the platform 10, is provided at the center of the upper part of the turntable 31. A second heating water tank 35 is installed at the bottom opening of the condensation tank 32, and a heating rod is also installed inside 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 tank 32. Thus, based on the demonstration of the liquid water condensation process on the turntable 31, it is easier for more viewers to observe the condensation process of liquid water.

[0033] The liquid demonstration component 30 in this application can also be combined with the gaseous demonstration component 20 and the solid demonstration component 40 to form a three-state water demonstration device. In order to facilitate a further understanding of the technical solution described in this application, the three-state water demonstration device formed by the combination of the gaseous demonstration component 20, the liquid demonstration component 30 and the solid demonstration component 40 will be further described in this application.

[0034] The gaseous demonstration component 20, the liquid demonstration component 30, and the solid demonstration component 40 are all mounted on the platform 10.

[0035] like Figure 2 and Figure 3As shown, the liquid demonstration component 30 includes a first water tank 27 and a first atomizer 26 installed inside the first water tank 27. A resiliently adjustable 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 to the first water tank 27, and a through hole 23 for airflow is provided in the middle of the pressure plate 21. In this application, the water in the first water tank 27 is atomized by the first atomizer 26 to form white vapor. Using white vapor instead of water vapor, which is invisible to the naked eye, ensures a high level of safety in the demonstration. Furthermore, the resiliently adjustable pressure plate 21 at the top opening of the first water tank 27 allows viewers to press the pressure plate 21, causing a pressure change within the first water tank 27, thereby expelling the atomized white vapor through the through hole 23. As viewers repeatedly press the pressure plate 21, white vapor continuously sprays out from the through hole 23, providing high visual appeal and entertainment value. This also enhances the interactivity of the demonstration device, making it suitable not only for classroom teaching but also for autonomous interactive demonstrations in science museums and other exhibition halls.

[0036] Based on the above, such as Figure 3 As shown, a vertically arranged guide telescopic rod 24 is installed inside the first water tank 27. A return spring 25 for driving the pressure plate 21 to rise is sleeved on the guide telescopic rod 24, ensuring the stability of the lifting and lowering movement of the pressure plate 21. In addition, the outer periphery of the pressure plate 21 forms a sealed fit with the first water tank 27 through a silicone plate 22. Compared with the sliding seal fit between the outer periphery of the pressure plate 21 and the first water tank 27, this not only provides a better sealing effect but also effectively reduces the resistance during the lifting and lowering process of the pressure plate 21.

[0037] like Figure 6 and Figure 7 As shown, the solid-state demonstration component 40 includes a second water tank 44 installed inside the platform 10 and a plate-type cooler 41 installed on the platform surface of the platform 10. The cooling plate surface of the plate-type cooler 41 is arranged parallel to the platform surface to hold liquid water and condense the liquid water into thin ice. The second water tank 44 is connected to a nozzle 43 that can spray water onto the cooling plate surface. After the liquid water condenses into thin ice, the morphology of the thin ice can be observed through a polarizing observation lens 42 set directly above the cooling plate surface, which facilitates further observation and understanding of the internal morphology of the solid water.

[0038] Based on the above, such as Figure 7 As shown, the polarizing observation mirror 42 can swing around a vertical axis distributed beside the plate cooler 41. By rotating the polarizing observation mirror 42, the morphological differences of thin ice at different locations can be observed, facilitating viewers' further understanding of the differences in the internal morphology of solid water. Furthermore, as... Figure 6 As shown, the polarizing observation lens 42 is set to at least two sets, which can be used for observation by multiple people.
