Description

Technical Field

[0001] The utility model relates to the field of teaching tools, in particular to a device for demonstrating the principle of a Hero fountain. Background Art

[0002] The Hero Fountain is an ingenious mechanical device invented by the ancient European scientist Hero. Its working principle is: mainly in a closed container, it uses the water level difference between containers at different heights, and uses the potential energy of the water at high places to generate compressed air, thereby driving the water at low places to spray upwards; the most intuitive effect of the Hero Fountain is that the water column sprayed out can exceed the highest liquid level without external power, changing people's inertial thinking that "water flows to low places". When people first saw the water at low places spraying upwards like a fountain, they were surprised and thought it violated the law of conservation of energy in physics. During classroom teaching, it is difficult for teachers to make students clearly understand the principle of the Hero Fountain by just verbal description.

[0003] The prior art (announcement number: CN208985478U, announcement date: 2019.06.14) discloses a Hero fountain demonstration device, which can perform repeated experiments using a repeated inversion device, and is disassembled for easy transfer and transportation; however, its structural design is complex, and the sealing of each connection part will be relatively reduced after repeated disassembly, transfer and transportation, and there is a defect of high manufacturing cost.

[0004] Currently, there are few demonstration devices of the Hero Fountain principle on the market. Although the device can be prepared manually based on its principle, it requires the use of at least three connecting pipes, and the sealing of each connecting part is difficult to ensure. In addition, at least two bottles are required, the structure is less firm, and it is inconvenient to assemble and carry. The overall manufacturing cost is relatively high. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] A demonstration device for the principle of a Hero fountain, comprising an inner bottle, a bottle cap, a bottle with openings at both ends and an outer packaging bottle;

[0007] The bottle cap seals the bottle mouth at the top of the inner bottle, and a first conduit is installed on the bottle cap, the upper end of the first conduit is higher than the bottle cap, and the lower end of the first conduit is located at the bottom end of the inner bottle;

[0008] A second conduit is installed on the bottom side of the inner bottle, the upper end of the second conduit is located at the top of the inner bottle, and the lower end of the second conduit is arranged below the inner bottle;

[0009] The inner bottle is fixedly installed to cover the top of the bottle with openings at both ends, and the bottom of the bottle with openings at both ends is fixedly installed in the outer packaging bottle;

[0010] The inner bottle and the bottle with openings at both ends are installed in the outer packaging bottle with clearance fit.

[0011] Furthermore: the bottle cap seals the bottle mouth at the top of the inner bottle through screw fitting.

[0012] Further: a first through hole is formed on the bottle cap, and the first conduit is sealed and installed in the first through hole.

[0013] Further: a second through hole is formed on the bottom side of the inner bottle, and the second conduit is sealed and installed in the second through hole.

[0014] Furthermore: the inner bottle and the bottles with openings at both ends are sealed and connected to each other.

[0015] Further: the inner side surface of the upper end of the bottle with openings at both ends is formed with a widened inner hole, the inner diameter of the widened inner hole is larger than the inner diameter of the bottle with openings at both ends, and the inner bottle is fixedly installed in the widened inner hole.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. All parts can be fixed into the outer packaging bottle, which is convenient to carry. There is no need to assemble during use or disassemble after use. It has the advantages of high stability, good sealing and low manufacturing cost.

[0018] 2. When the water in the inner bottle runs out, the Hero fountain will automatically stop. At this time, place the outer bottle in the opposite direction, so that the water in the bottle with both ends open can flow into the inner bottle through the second conduit. There is no need to add water to the inner bottle again, which makes the sealing better. The water in the outer bottle can be poured out.

[0019] 3. Transparent materials can be used to make the inner bottle, the bottle with openings at both ends and the outer packaging bottle, so that the operating principle of the Hero Fountain can be directly observed from the outside.
