Description

Technical Field

[0001] The utility model relates to the technical field of storm bottle principle demonstration, in particular to a storm bottle principle demonstration device. Background Art

[0002] A storm bottle, also known as a weather bottle, consists of a sealed glass container containing a transparent solution mixed with a variety of chemical substances. The container can produce different crystal forms as the chemical substances in the solution change with external conditions.

[0003] The existing storm bottle principle demonstration device mainly consists of a sealed glass bottle and a mixed solution. The mixed solution usually includes distilled water, ethanol, potassium nitrate, ammonium chloride and camphor. These chemicals interact in the solution to form a unique crystallization phenomenon. The working principle of the storm bottle is based on changes in external temperature and weather conditions, which cause the chemicals in the solution in the bottle to react, thereby showing different forms of crystals.

[0004] Abstract: The existing storm bottle principle demonstration device mainly relies on the changes in the external weather environment. When the ambient temperature fluctuates slightly, the temperature of the solution in the storm bottle will also be relatively stable, resulting in the crystal morphology in the storm bottle may not show obvious changes. This makes it difficult for observers to see the expected crystal morphology changes, thereby failing to achieve the simulation demonstration of the storm bottle principle and affecting the demonstration effect. Therefore, a storm bottle principle demonstration device is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems raised in the above background technology, the utility model proposes a storm bottle principle demonstration device.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: a storm bottle principle demonstration device described in the present invention comprises a base; a fixing column is fixedly connected to the base, a sliding sleeve is provided on the bottom end of the fixing column, a connecting plate is fixedly connected to the sliding sleeve, a supporting plate is fixedly connected to the connecting plate, a circular hole is provided on the supporting plate, a plurality of supporting rods are fixedly connected to the top end of the circular hole, a fixing ring is fixedly connected to the bottom end of the circular hole, a heating tube is provided in the fixing ring, three support rods are fixedly connected to the inner wall of the fixing ring, a motor is installed in cooperation with the three support rods, a fan is installed at the output end of the motor, an air vent groove is provided in the supporting plate, and the air vent groove is connected to the circular hole. During the demonstration, different solutions are mixed in the glass container, and chemical changes occur to form a unique crystallization phenomenon. Then, the motor is started to rotate, and the cooperation of the heating tube Under the action, the heated high-temperature gas can be blown to the surface of the glass container to heat the glass container. Because the solubility of the solution will change with the temperature, the solubility will increase as the temperature rises. After the glass container is heated to a high temperature, the crystals in the glass container will disappear and become transparent and clear. Then the heating tube is stopped and the motor is started alone to rotate the fan. The high-speed rotation of the fan allows the high-temperature gas to be quickly discharged from the air vent groove, so that the glass container can be cooled. As the temperature decreases, the solubility will also decrease, so that the crystallization phenomenon in the glass container reappears. By heating and cooling the glass container, the solution temperature in the storm bottle changes significantly, and then the crystal morphology in the storm bottle can be significantly changed, which allows the observer to intuitively observe the changes in the crystal morphology, thereby realizing a simulation demonstration of the storm bottle principle.

[0007] Preferably, a first screw hole is provided on the sliding sleeve, and a first locking bolt is rotatably assembled in the first screw hole, and the bottom end of the first locking bolt is in conflict with the outer surface of the fixing column. When using the device, by setting the first locking bolt, the sliding sleeve can drive the glass container to a suitable position, and then the sliding sleeve can be fixed by conflict, so that the position of the glass container can be adjusted as needed to facilitate better addition of solution into the glass container.

[0008] Preferably, four limiting rods are fixed to the top side wall of the support plate, and the four limiting rods are arranged around the circular hole. A control panel and a battery box are respectively installed on the top side of the base. When using the device, the glass container can be limited and fixed by setting the limiting rods to prevent the glass container from slipping.

[0009] Preferably, the fixed column is provided with a fixed sleeve, and a rotating ring is rotatably installed on the fixed sleeve. Limit sleeves are fixedly connected to both sides of the rotating ring, and bottles are slidably assembled in the two limit sleeves. The top ports of the two bottles are rotatably assembled with sealing covers, and the bottom ports of the two bottles are connected to discharge pipes, and the discharge pipes are equipped with one-way valves. When simulating the storm principle, the sealing cover is first opened, and a solution of potassium nitrate, ammonium chloride and distilled water is placed in one bottle, and a solution of camphor and ethanol is placed in the other bottle. Then, the bottle port is blocked by the sealing cover, and the rotating ring is rotated to make the bottle follow the movement until the material is discharged. The bottle drives the discharge pipe to rotate to the top of the glass container placed on the support plate in advance, and then the sliding sleeve is lifted upward, so that the support plate drives the glass container to move up close to the discharge pipe of the bottle. The sliding sleeve is fixed in the current position by the action of the first locking bolt, and the one-way valve is opened to allow potassium nitrate, ammonium chloride and distilled water solution to flow into the glass container. Then, the rotating ring is rotated to make the discharge pipe of another bottle rotate to the top of the glass container placed on the support plate, and the one-way valve is opened to allow camphor and ethanol solutions to flow into the glass container. The solutions are mixed in the glass container, and these chemical substances interact with each other in the solution to form a unique crystallization phenomenon.

[0010] Preferably, a second screw hole is provided on both limit sleeves, and a second locking bolt is rotatably assembled in each of the two second screw holes, and the end of the second locking bolt is in conflict with the outer surface of the bottle.

The motor is started to make the fan rotate. With the cooperation of the heating tube, the heated high-temperature gas can be blown to the surface of the glass container to heat the glass container. Because the solubility of the solution changes with the temperature, the solubility will increase as the temperature rises. After the glass container is heated to a high temperature, the crystals in the glass container will disappear and become transparent and clear. Then the heating tube is stopped and the motor is started alone to make the fan rotate. The high-speed rotation of the fan allows the high-temperature gas to be quickly discharged from the air vent groove, thereby cooling the glass container. Because the temperature drops, the solubility will also drop, so that the crystallization phenomenon in the glass container reappears. By heating and cooling the glass container, the temperature of the solution in the storm bottle changes significantly, and then the crystal morphology in the storm bottle changes significantly, which enables the observer to intuitively observe the change in the crystal morphology, thereby realizing a simulation demonstration of the storm bottle principle.

After a chemical change occurs and a unique crystallization phenomenon is formed, the motor 11 is started to rotate the fan 12. With the cooperation of the heating tube 10, the heated high-temperature gas can be blown to the surface of the glass container to heat the glass container. Because the solubility of the solution changes with temperature, the solubility will increase as the temperature rises. After the glass container is heated to a high temperature, the crystals in the glass container will disappear and become transparent and clear. Then the heating tube 10 is stopped and the motor 11 is started alone to rotate the fan 12. The high-speed rotation of the fan 12 allows the high-temperature gas to be quickly discharged from the air vent groove 13, thereby cooling the glass container. Because the temperature decreases, the solubility will also decrease, so that the crystallization phenomenon in the glass container reappears.

[0022] The fixed column 2 is provided with a fixed sleeve 15, and a rotating ring 16 is rotatably installed on the fixed sleeve 15. Limit sleeves 17 are fixed on both sides of the rotating ring 16. Bottles 18 are slidably installed in the two limit sleeves 17. The top ports of the two bottles 18 are rotatably equipped with sealing covers 21. The bottom ports of the two bottles 18 are connected to discharge pipes 19, and the discharge pipes 19 are equipped with a one-way valve 20. Second screw holes are provided on the two limit sleeves 17. Second locking bolts 22 are rotatably installed in the two second screw holes, and the ends of the second locking bolts 22 are in conflict with the outer surfaces of the bottles 18. When simulating the storm principle, the sealing covers 21 are first opened, and a solution of potassium nitrate, ammonium chloride and distilled water is placed in one bottle 18, and a solution of camphor and ethanol is placed in the other bottle 18, and then the sealing covers 21 are passed through the sealing covers 21. The port of the material bottle 18 is sealed, and then the rotating ring 16 is rotated to make the material bottle 18 move with it until the material bottle 18 drives the discharge pipe 19 to rotate to the top of the glass container placed on the support plate 5 in advance, and then the sliding sleeve 3 is lifted upward so that the support plate 5 drives the glass container to move up close to the discharge pipe 19 of the material bottle 18, and the sliding sleeve 3 is fixed in the current position by the first locking bolt 6, and the one-way valve 20 is opened to allow potassium nitrate, ammonium chloride and distilled water solution to flow into the glass container, and then the rotating ring 16 is rotated to make the discharge pipe 19 of another material bottle 18 rotate to the top of the glass container placed on the support plate 5, and the one-way valve 20 is opened to allow camphor and ethanol solutions to flow into the glass container, so that the solutions are mixed in the glass container, and these chemical substances interact in the solution to form a unique crystallization phenomenon.

[0023] Working principle: Since the existing storm bottle principle demonstration device mainly relies on the changes in the external weather environment, when the ambient temperature fluctuates slightly, the temperature of the solution in the storm bottle will also be relatively stable, resulting in the crystal morphology in the storm bottle may not show obvious changes, which makes it difficult for observers to see the expected crystal morphology changes, thereby failing to achieve the simulation demonstration of the storm bottle principle and affecting the demonstration effect; Therefore, in order to solve the above problems, a storm bottle principle demonstration device is proposed; when simulating the storm principle, first open the sealing cover 21, put a solution of potassium nitrate, ammonium chloride and distilled water into a material bottle 18, and the other material bottle 18 is put into camphor and ethanol solution, and then the port of the bottle 18 is sealed by the sealing cover 21. Then the rotating ring 16 is rotated to make the bottle 18 move with it until the bottle 18 drives the discharge pipe 19 to rotate to the top of the glass container pre-placed on the support plate 5. Then the sliding sleeve 3 is lifted upward to make the support plate 5 drive the glass container to move close to the discharge pipe 19 of the bottle 18. The sliding sleeve 3 is fixed in the current position by the first locking bolt 6. The one-way valve 20 is opened to allow potassium nitrate, ammonium chloride and distilled water solution to flow into the glass container. Then the rotating ring 16 is rotated to make the discharge pipe 19 of the other bottle 18 Go to the top of the glass container placed on the support plate 5, open the one-way valve 20, and let the camphor and ethanol solutions flow into the glass container to mix the solutions in the glass container. These chemical substances interact with each other in the solution to form a unique crystallization phenomenon. Then start the motor 11 to rotate the fan 12. With the cooperation of the heating tube 10, the heated high-temperature gas can be blown to the surface of the glass container to heat the glass container. Because the solubility of the solution changes with temperature, the solubility will increase as the temperature rises. After the glass container is heated to a high temperature, the crystals in the glass container will disappear and become transparent and clear. Then stop the heating tube 10 and start the motor 11 separately to rotate the fan 12. The high-speed rotation of the fan 12 allows the high-temperature gas to be quickly discharged from the air vent groove 13, thereby cooling the glass container. As the temperature decreases, the solubility will also decrease, and the crystallization phenomenon in the glass container will reappear. By heating and cooling the glass container, the temperature of the solution in the storm bottle will change significantly, and the crystal morphology in the storm bottle will change significantly. This allows the observer to intuitively observe the change in the crystal morphology, thereby realizing a simulation demonstration of the storm bottle principle.
