For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0025] like Figures 1 to 3 As shown, a simulated vortex demonstration device, wherein this embodiment includes a base 1 and a transparent cup body 2 installed on the base 1, a water circulation chamber 11 connected to the transparent cup body 2 and an air chamber 12 arranged on the side of the water circulation chamber 11 are provided in the base 1, a vortex generating mechanism 3 for simulating the formation of a vortex in the transparent cup body 2 is provided in the water circulation chamber 11, and a floating luminous member 4 for floating on the water body is provided in the transparent cup body 2, a bubble stone 5 connected to the air chamber 12 is embedded in the bottom of the transparent cup body 2, and an air pump 6 connected to the air chamber 12 for generating gas and transmitting it to the air chamber 12 to generate bubbles through the bubble stone 5 is provided outside the base 1.

[0026] In this embodiment, water is injected into the transparent cup body 2 fixed on the base 1, and the base 1 is divided into two layers of chambers, namely, a water circulation chamber 11 directly connected to the transparent cup body 2 and an air chamber 12 surrounding the water circulation chamber 11. A vortex generating mechanism 3 is arranged in the water circulation chamber 11 to drive the water to form a vortex in the transparent cup body 2, which intuitively shows the dynamic process of the vortex from scratch and gradually developing. An air pump 6 connected to the air chamber 12 in the base 1 is installed outside the base 1. The air pump 6 can continuously compress the external air and transport it to the inside of the air chamber 12. A ring-shaped bubble stone 5 is arranged on the side of the bottom of the transparent cup body 2 corresponding to the air chamber 12. The gas generated by the air pump 6 is transported to the bubble stone 5 located at the bottom of the transparent cup body 2 through the air chamber 12. The bubble stone 5 is a material designed with many tiny pores. When the high-pressure gas passes through these micropores, the pressure drops suddenly, and the gas is released from each pore to form many tiny bubbles. Many bubbles are spherical due to surface tension and begin to rise. A floating luminous member 4 is provided in the transparent cup body 2 and can float on the water in the cup. The floating luminous member 4 and the rising numerous bubbles move with the vortex motion and can be seen to descend with the vortex with the naked eye. When the vortex is eliminated, the bubbles return to their original positions due to buoyancy, which makes it easy for students to observe the flow pattern inside the vortex.

[0027] like Figure 1 As shown, in this embodiment, a fixed flange 7 is further provided between the base 1 and the transparent cup body 2, and a connecting port 71 for connecting the water circulation chamber 11 and the transparent cup body 2 is further provided at the center of the fixed flange 7, and the diameter of the connecting port 71 is smaller than the diameter of the floating luminous member, and the vortex production mechanism includes a submersible pump 31 and a water outlet pipe 32 arranged in the water circulation chamber 11, one end of the water outlet pipe 32 is connected to the submersible pump 31, and the other end is plugged into the transparent cup body 2. Specifically, when the submersible pump 31 located in the water circulation chamber 11 is started, its built-in impeller begins to rotate, and the water body is extracted from the transparent cup body 2 through the connecting port 71, and the water flow is sent to the water outlet pipe 32 by pressurization, and then injected into the cup body. When the water flow is injected into the transparent cup body 2 at a certain speed and angle, according to the principle of momentum conversion and water body continuity, the water flow forms a downward flow in the central area of ​​the cup body, while in the peripheral area, due to the effect of friction and pressure difference, the water flow flows upward. In this way, the water forms a spiral vortex flow in the cup.

[0028] like Figure 2As shown, the floating light-emitting member 4 of this embodiment includes a transparent lampshade 41 and a lamp holder 42 disposed in the transparent lampshade 41, and LED light boards 421 and power supply components 422 electrically connected to the LED light boards 421 are disposed on both sides of the lamp holder 42, and a hollow cavity 43 for providing buoyancy is disposed in the transparent lampshade 41. The transparent lampshade 41 is composed of two semicircular shells 411, and a sealing ring 412 for preventing water from entering is also disposed between the shell and the lamp holder 42. The floating light-emitting member 4 is mainly composed of a transparent lampshade 41 and an internal lamp holder 42. The transparent lampshade 41 is formed by splicing two semicircular shells 411, and is a hollow structure in the shell, which can ensure good light transmittance while floating on the water body, allowing the light to be evenly scattered, and LED light boards 421 are installed on both sides of the lamp holder 42, which can ensure 360-degree omnidirectional light emission, and a plurality of battery holders are disposed on the lamp holder 42, and a plurality of button batteries for powering the LED light boards 421 are disposed in the battery holder. A sealing ring 412 is disposed between the semicircular shells 411 to prevent moisture from penetrating into the internal circuit.

[0029] like Figure 1 As shown, the top of the transparent cup body 2 of this embodiment is provided with a water inlet 8 and a top cover 9 detachably connected to the transparent cup body 2 for closing the water inlet 8. The water in the transparent cup body 2 can be changed and the inside of the transparent cup body 2 can be cleaned at the water inlet 8 by opening the top cover 9.

[0030] In summary, the beneficial effects of this embodiment are as follows: this embodiment can simulate the formation of a vortex in the transparent cup body 2 through the submersible pump 31, the connecting port 71, and the water outlet pipe 32, while the air pump 6 and the bubble stone 5 can generate bubbles in the cup body, and the movement trajectory in the vortex can be observed in conjunction with the floating luminous part 4.

[0031] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
