Description

Technical Field

[0001] This invention relates to the field of teaching aids technology, specifically a combined water clock exploration teaching tool. Background Technology

[0002] Water clocks in China are also called "clepsydras" or "water clocks." Based on the principle of isochronism, there are two methods for recording time by dripping water: one uses a special container to record the time it takes for the water to drain completely (outflow type), and the other uses a container with an open bottom to record how long it takes to fill (receiving type). Chinese water clocks initially used the outflow type, but later both types were used simultaneously or combined. Around 85 AD, receiving-type water clocks with a swivel on the float gradually became popular and were widely used. However, most teaching methods currently available on the market involve simply drilling holes in beverage bottles, inverting them, and marking water levels to create a rudimentary water clock. Students often fail to consider air pressure during construction, leading to changes in flow rate, and the bottles are relatively soft and easily deformed. Some teaching aids have complex structures, are difficult to assemble, and only offer one combination; multi-stage water clocks, similar to those in science museums, are also very expensive. Therefore, this paper proposes a combined water clock as an inquiry-based teaching aid to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a combined water clock exploration teaching aid to solve the problem of the inability to achieve a good balance between cost and ease of use in existing teaching aids.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A combined water clock exploration teaching aid includes a connector. The connector includes an outer fixing shell, an inner fixing tube installed on the inner side of the outer fixing shell, and hollow grooves evenly opened on the inner side of the outer fixing shell. Limiting rings are evenly installed on the top of the outer fixing shell, a top ring is installed on the top of the inner fixing tube, mounting holes are evenly opened on the outer side of the top ring, and a through-hole is installed on the inner side of the inner fixing tube.

[0006] Preferably, a first bottle body is installed at the bottom end of the connector, the inner diameter of the first bottle body is equal to the outer diameter of the outer fixed shell, an inner bracket is installed on the inner side of the connector, the outer side of the inner bracket is fitted with the connector, and a floating block structure is slidably connected to the inner side of the inner bracket.

[0007] Preferably, the first bottle body is made of a plastic bottle with the top cone-shaped structure removed, and a drain pipe is connected to the bottom of the outer side of the first bottle body.

[0008] Preferably, the upper end of the float structure is divided into a straw, and the lower end of the float structure is divided into a foam block.

[0009] Preferably, a second bottle is installed on the outer side of the bottom end face of the connector, and the inner diameter of the second bottle is equal to the outer diameter of the outer fixing shell. A third bottle is installed on the inner side of the top end face of the connector, and the cap of the third bottle is provided by perforation or by connecting tube.

[0010] Preferably, a water valve is installed in the middle part of the connecting pipe.

[0011] Preferably, the second bottle body is formed by cutting off the top conical structure of a plastic bottle, and the second bottle body is formed by cutting off the bottom structure of a plastic bottle.

[0012] Preferably, the inner support includes a bottle cap, an upper annular magnet, a lower annular magnet, and a thick straw. The thick straw passes through the inner side of the bottle cap, and the upper annular magnet and the lower annular magnet are installed on the outer side of the thick straw in an up-down arrangement. The inner sides of the upper annular magnet and the lower annular magnet are both in contact with the thick straw.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In this invention, by using a connector, a cleverly designed combination of connectors can be used to form a draining type floating arrow leak, a draining type arrow leak, a water receiving type arrow leak, a multi-stage drip leak, or a combined overflow type drip leak, based on a plastic bottle as the container. This not only has low production and usage costs, but also provides relatively stable performance in actual use, thus facilitating its use in teaching. Attached Figure Description

An inner fixing tube 3 is installed on the inner side of the outer fixing shell 2. Hollow grooves 4 are evenly opened on the inner side of the outer fixing shell 2. Limiting rings 5 ​​are evenly installed on the top of the outer fixing shell 2. A top ring 6 is installed on the top of the inner fixing tube 3. Mounting holes 7 are evenly opened on the outer side of the top ring 6. A through-hole 14 is installed on the inner side of the inner fixing tube 3.

[0025] The bottom end of connector 1 is fitted with a first bottle body 8. The inner diameter of the first bottle body 8 is equal to the outer diameter of the outer fixed shell 2. An inner support 10 is installed on the inner side of connector 1. The outer side of the inner support 10 is fitted with connector 1. A float structure 11 is slidably connected to the inner side of the inner support 10. This arrangement ensures the stability of installation and use. The first bottle body 8 is made of a plastic bottle with the top cone structure cut off. The bottom end of the outer side of the first bottle body 8 is connected to a drain pipe 9. The upper end of the float structure 11 is divided into a straw, and the lower end of the float structure 11 is divided into a foam block. The inner support 10 includes a bottle cap 19, an upper annular magnet 18, a lower annular magnet 20, and a coarse straw 17. The coarse straw 17 passes through the inner side of the bottle cap 19. The upper annular magnet 18 and the lower annular magnet 20 are installed on the outer side of the coarse straw 17 in an up-down arrangement. The inner sides of the upper annular magnet 18 and the lower annular magnet 20 are both fitted with the coarse straw 17. This arrangement can effectively reduce the cost of production and use.

[0026] Workflow: When using this device, the top of the plastic bottle is first cut off to form the first bottle body 8. Then, the float structure 11 is placed into the first bottle body 8. Next, the connector 1 is installed inside the top of the first bottle body 8. Then, the inner bracket 10 is installed inside the connector 1. When installing the inner bracket 10, the top of the float structure 11 is fitted inside the inner bracket 10, thus assembling the device. When assembling the inner bracket 10, the coarse straw 17 is passed through the bottle cap 19. Then, the coarse straw 17 is fixed by the friction between the magnets and the coarse straw 17 by the inner and outer sides of the bottle cap 19 and the outer ring magnet 18 and the lower ring magnet 20. Finally, the coarse straw 17 is fixed to the bottle cap 19 by the upper ring magnet 18 and the lower ring magnet 20.
