Description

[0002] Archimedes' principle is a fundamental principle of mechanics in physics, stating that an object immersed in a liquid (or gas) experiences an upward buoyant force equal to the weight of the liquid displaced by the object. The formula can be written as: F_buoyant = G_displaced = ρ_liquid * g * V_displaced_liquid.

[0003] In buoyancy science demonstrations, buoyancy is one of the key points. How liquid buoyancy is generated, the reasons for its generation, and the factors affecting liquid buoyancy are always challenging aspects of the demonstration. If these are not demonstrated effectively, it is difficult for the audience to understand the principles simply by explaining. Therefore, science communicators usually use physical buoyancy experiments or relevant videos to assist in the demonstration.

[0004] However, existing technologies typically demonstrate buoyancy by comparing the mass of a heavy object with buoyancy, which does not provide a very intuitive demonstration of buoyancy and prevents the target audience from gaining a flexible and profound understanding of Archimedes' principle. If the demonstration is conducted by watching related videos, the audience will have a poor experience. Summary of the Invention

Detailed Implementation

[0022] To facilitate understanding of this application, a more comprehensive description will be provided below with reference to the accompanying drawings. Preferred embodiments of this application are also given. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this application.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please refer to Figures 1 to 5 This application illustrates, through the following embodiments, a display device for simulating buoyancy, including a display stand 100, a simulation device 200, and an operating component 300, wherein:

[0025] The exhibition stand 100 includes a stand body 110 and a table surface 120. The table surface 120 is disposed on the stand body 110 and has a positioning groove 121. The operating component 300 is disposed on one side of the stand body 110. The simulation device 200 includes a submarine simulation component 210. The submarine simulation component 210 includes a first transparent water tank 211, a flexible submarine simulator 212, and a gas extraction component 213. The gas extraction component 213 is disposed inside the stand body 110. The first transparent water tank 211 is disposed on the positioning groove 121 and contains a solution. The flexible submarine simulator 212 is placed inside the first transparent water tank 211 and has a cavity inside. The gas extraction component 213 communicates with the cavity and is electrically connected to the operating component 300.

[0026] The size of the display stand 100 can be specifically designed according to the actual production batch or specified requirements. In this embodiment, the length, width, and height of the display stand 100 are 1.6m, 0.9m, and 1.6m, respectively. The first transparent water tank 211 can be made of glass, plastic, or other transparent materials. In this embodiment, preferably, the first transparent water tank 211 is made of acrylic material. Furthermore, the first transparent water tank 211 can be designed with a detachable top cover, which can be closed onto the first transparent water tank 211 during use. The size and shape of the positioning groove 121 are respectively... The size and shape of the bottom of the first transparent water tank 211 are matched, and the first transparent water tank 211 can be embedded in the positioning groove 121; the flexible submarine simulation component 212 is a model of a submarine shape, the flexible submarine simulation component 212 is made of flexible material (its density should be greater than the density of the solution), and the flexible submarine simulation component 212 has a cavity inside, the gas extraction component 213 is connected to the cavity, the gas extraction component 213 can pump air into the cavity and extract the gas in the cavity, and the gas extraction component 213 is electrically connected to the operating component 300.

[0027] In use, the user first triggers the operation component 300, which controls the gas extraction component 213 to extract gas from the cavity. At this time, the volume of the flexible submarine simulator 212 decreases, its mass remains basically unchanged, but its displacement decreases. Simultaneously, the buoyancy of the flexible submarine simulator 212 decreases, and the flexible submarine simulator 212 sinks. Then, the operation component 300 controls the gas extraction component 213 to pump air into the cavity. At this time, the volume of the flexible submarine simulator 212 increases, its mass remains basically unchanged, but its displacement increases. Simultaneously, the buoyancy of the flexible submarine simulator 212 increases, and the flexible submarine simulator 212 rises.

[0028] The user (the target audience for science education) controls the gas extraction component 213 to pump or pump air into the cavity through the operating component 300. By changing the volume of the flexible submarine simulator 212, the displacement of the flexible submarine simulator 212 is changed, thereby changing the buoyancy of the flexible submarine simulator 212.

[0029] The buoyancy simulation device provided in this application is simple and convenient to operate. It demonstrates Archimedes' principle to users (scientific education subjects) through the rising and sinking of the flexible submarine simulator 212, allowing users (scientific education subjects) to experience and deepen their understanding of Archimedes' principle more intuitively. At the same time, the direct participation of scientific education subjects can enhance their experience.

[0030] Specifically, the operating component 300 can be two switches, and the gas extraction component 213 can have an air pump 2131. When the user (the target audience) turns on the first switch, the air pump 2131 extracts the gas from the cavity. When the user (the target audience) turns on the second switch, the air pump 2131 pumps air into the cavity. The forward extraction and reverse inflation of the air pump 2131 are controlled by the two switches. This is existing technology and can be achieved by conventional means by those skilled in the art.

[0031] Furthermore, in some specific embodiments, the gas delivery component 213 includes an air pump 2131 and a flexible vent pipe 2132. One end of the flexible vent pipe 2132 is connected to the air pump 2131, and the other end of the flexible vent pipe 2132 is connected to the cavity. The air pump 2131 is electrically connected to the operating component 300.

[0032] In this embodiment, the flexible venting tube 2132 can be a rubber hose, one end of which is connected to the cavity, and the other end of which is connected to the air pump 2131. The air pump 2131 is connected to the operating component 300. In use, triggering the operating component 300 (switch) causes the air pump 2131 to inflate the cavity through the rubber hose, causing the flexible submarine simulator 212 to rise; triggering the operating component 300 (switch) causes the air pump 2131 to extract gas from the cavity through the rubber hose, causing the flexible submarine simulator 212 to sink.

[0033] In the above text, the solution can be water. To improve the floating or sinking effect of the flexible submarine simulator 212, in some preferred embodiments, the density of the solution is less than that of water. The solution can be alcohol, vegetable oil, sesame oil, etc., and in this embodiment, silicone oil is preferred.

[0034] Preferably, a sealing ring 1211 is fitted onto the positioning groove 121. The sealing ring 1211 fitted onto the positioning groove 121 can provide a fastening effect, making the first transparent water tank 211 more stable when placed in the positioning groove 121.

[0035] The above embodiments change the volume of the flexible submarine simulator 212 to change its displacement, thereby changing the buoyancy and enabling the simulator 212 to rise and sink. To further explore how changing the solution density can alter buoyancy, in some optional embodiments, the simulation device 200 also includes a ship simulation component 220. This component includes a second transparent water tank 221, a ship simulator 222, and a bubble generator 223. The second transparent water tank 221 is disposed on the platform 120 and contains a solution (which can be water). The ship simulator 222 is placed inside the second transparent water tank 221. The bubble generator 223 is disposed within the platform 110 and communicates with the bottom of the second transparent water tank 221. Initially, the ship simulator 222 floats on the surface of the solution within the second transparent water tank 221.

[0036] In this embodiment, the material used to make the second transparent water tank 221 can be the same as that used to make the first transparent water tank 211. Preferably, the second transparent water tank 221 is made of acrylic material. The height of the second transparent water tank 221 is slightly lower than that of the first transparent water tank 211, and the second transparent water tank 221 has no top cover. The ship simulation component 222 is a model of a ship. In the initial stage, the ship simulation component 222 floats on the solution. Preferably, the solution is silicone oil. The bubble generator 223 is used to pump air into the second transparent water tank 221, and the gas is injected from the bottom of the second transparent water tank 221. At this time, the gas will generate bubbles in the solution.

[0037] When in use, the science popularizer first turns on the bubble generator 223, which pumps air into the second transparent water tank 221. Several bubbles are generated in the second transparent water tank 221, the density of the solution in the second transparent water tank 221 decreases, the buoyancy of the ship simulation component 222 decreases, and the ship simulation component 222 sinks.

[0038] In this embodiment, the buoyancy is changed by altering the density of the solution, causing the ship simulator 222 to sink. In the previous embodiment, the displacement of the flexible submarine simulator 212 was changed by altering its volume, thereby changing its buoyancy and causing the flexible submarine simulator 212 to float or sink. By setting up the submarine simulator 210 and the ship simulator 220, objects can float and sink in two different ways, further improving the user's (science popularization target's) experience and enhancing the quality of science popularization.

[0039] Considering that when the bubble generator 223 is connected to the second transparent water tank 221, using a pipe to connect them will result in the bubbles generated in the second transparent water tank 221 being relatively concentrated and not evenly distributed. Furthermore, in some preferred embodiments, a countersunk hole 122 is provided on the platform 120. The countersunk hole 122 includes a first hole 1221 and a second hole 1222. The diameter of the first hole 1221 is larger than the diameter of the second hole 1222. The second hole 1222 is located below the first hole 1221 and extends in a conical shape towards the inner bottom of the platform 120 and passes through the inner bottom of the platform 120. A conical vent 2211 is provided on the bottom surface of the second transparent water tank 221 extending downward. A vent hole 2212 is provided on the bottom surface of the second transparent water tank 221 at a position corresponding to the conical vent 2211. The second transparent water tank 221 is placed in the first hole 1221. The air outlet of the bubble generator 223 is connected to the conical vent 2211.

[0040] The shape and size of the first hole 1221 match the shape and size of the bottom of the second transparent water tank 221, allowing the bottom of the second transparent water tank 221 to fit snugly inside the first hole 1221. The second hole 1222 is located below the first hole 1221, and the diameter of the first hole 1221 is larger than the diameter of the second hole 1222. The first hole 1221 passes through the platform 120, thus primarily supporting the second transparent water tank 221. The second hole 1222 extends conically towards the inner bottom of the platform 120, passing through the inner bottom of the platform 120 and reaching into the platform body 110. A conical vent 2211 extends downward from the bottom surface of the second transparent water tank 221. When the second transparent water tank 221 is placed inside the first hole 1221, the size, shape, and height of the conical vent 2211 match the size, shape, and height of the second hole 1222, respectively. The vent 2212 is located on the bottom surface of the second transparent water tank 221, corresponding to the conical vent 2211. The outlet end of the bubble generator 223 is connected to the conical vent 2211. In use, the bubble generator 223 is turned on, and the gas enters the conical vent 2211 from the outlet end of the bubble generator 223. The gas in the conical vent 2211 then enters the second transparent water tank 221 through the vent 2212 on the bottom surface of the second transparent water tank 221, generating bubbles.

[0041] The advantage of this arrangement is that the gas generated by the bubble generator 223 first enters the conical vent 2211, and then passes through the vent 2212 at the bottom of the second transparent water tank 221. Since there are multiple vents 2212, when the gas enters the vent 2212, the generated bubbles can be evenly distributed at the bottom of the second transparent water tank 221 and gradually rise, changing the density of the solution.

[0042] Furthermore, in some specific embodiments, the bubble generator 223 includes an air pump 2231, which is disposed within the platform 110. The air outlet of the air pump 2231 passes through the second hole 1222 via an air inlet pipe 2232 and communicates with the air vent 2211. The air pump 2231 is equipped with a manual operating component 400 (which may be a switch). The air pump 2231 is used to provide gas, causing bubbles to be generated in the second transparent water tank 221. It should be noted that the operating component on the air pump 2231 can be electric or manual. In this embodiment, a manual operating component 400 is preferred to increase the participation of the user (the target audience for science education). Specifically, when the user (the target audience for science education) triggers the manual operation device 400, the air pump 2231 generates gas, which enters the conical air inlet 2211 through the air inlet pipe 2232, enters the second transparent water tank 221 through the vent hole 2212, and generates bubbles.

[0043] Considering that the solution in the second water tank may flow back into the air inlet pipe 2232, in some preferred embodiments, a one-way valve 2233 is provided on the air inlet pipe 2232.

[0044] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
