Description

Technical Field

[0001] This utility model relates to the field of experimental technology for exploring the power of air, and in particular to an experimental device that can be combined for exploring the power of air. Background Technology

[0002] Air is ubiquitous in our lives, yet intangible; it is the gas surrounding the Earth. Layered and covering the Earth's surface, it is transparent, colorless, and odorless. Primarily composed of nitrogen and oxygen, it plays a vital role in human survival and production. Air is a mixture of gases in the Earth's atmosphere, mainly composed of nitrogen, oxygen, rare gases (helium, neon, argon, krypton, xenon, radon), carbon dioxide, and other substances (such as water vapor and impurities). Nitrogen comprises approximately 78% by volume, oxygen approximately 21%, rare gases (helium, neon, argon, krypton, xenon, radon) approximately 0.934%, carbon dioxide approximately 0.04%, and other substances (such as water vapor and impurities) approximately 0.02%.

[0003] Air contains various forms of energy. For example, blowing air onto an object can cause it to move, and when an object moves, it is subject to air resistance.

[0004] To help children better understand the power of air, they are usually taken to science museums to observe and learn from professional equipment, or to conduct experiments using professional equipment. However, these methods are not only cumbersome and costly, but the professional equipment is also not easy to carry. Therefore, we propose an experimental device that can be combined to explore the power of air. Utility Model Content

[0005] The purpose of this invention is to provide an experimental device that can be combined to explore the power of air. By setting up an experimental mechanism, a support assembly and stepped rods are used to support a small ball, and an air blowing assembly is used to blow air onto the ball. The movement of the ball helps children understand the power of air.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an experimental device that can be assembled to explore the power of air, comprising a small ball, with an experimental mechanism disposed below the small ball, the experimental mechanism comprising:

[0007] The support assembly is provided on both sides of the bottom of the ball;

[0008] Multiple stepped rods are connected between adjacent support assemblies, and the support assemblies cooperate with the multiple stepped rods to support the ball;

[0009] An air blowing assembly is located on one side of the bottom of the ball and is used to blow the ball.

[0010] Preferably, the bracket assembly includes a side plate, a stepped groove formed on one side of the side plate, and a plurality of connecting holes formed on the top side of the side plate.

[0011] Preferably, the air blowing assembly is composed of an L-shaped air blowing tube, wherein one end of the L-shaped air blowing tube is configured as the air blowing end, and the other end of the L-shaped air blowing tube is configured as the air outlet end.

[0012] Preferably, the overall outline of the side plate is set as a right-angled triangle, and the stepped groove is opened on the inclined side of the side plate.

[0013] Preferably, the stepped rod includes a connecting rod and hemispherical protrusions connected to both ends of the connecting rod, and the two hemispherical protrusions are integrally formed with the connecting rod.

[0014] Preferably, the distribution profile of the plurality of connecting holes changes with the distribution profile of the stepped groove, and the ball rests between two adjacent connecting rods.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] By connecting the stepped rods to two support components, the design is assembled. A small ball is then placed on the two adjacent stepped rods at the bottom. The child then uses the air blowing component to blow air onto the bottom of the ball, causing it to rise along the stepped rods. The child can blow different volumes of air using the air blowing component, resulting in different upward speeds and paths for the ball. This helps the child understand concepts such as airflow, wind speed, and pressure. The design uses an experimental mechanism, with support components and stepped rods to support the ball, and the air blowing component to blow air onto the ball, allowing the child to understand the power of air through the ball's movement. The overall structure is simple, easy to disassemble and assemble, convenient for children to operate independently, and easy to carry. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-3 An experimental apparatus for exploring the power of air, shown, includes a small ball 3. An experimental mechanism is positioned below the ball 3, comprising: a support assembly 1, with support assemblies 1 on both sides of the bottom of the ball 3; multiple stepped rods 2, connected between adjacent support assemblies 1, with the support assemblies 1 and the stepped rods 2 working together to support the ball 3; and an air blowing assembly 4, located on one side of the bottom of the ball 3, used to blow air onto the ball 3. When assembling and using the experimental mechanism, the stepped rods 2 are used in conjunction with... Two support components 1 are connected to form a single unit. Then, a small ball 3 is placed on two adjacent step rods 2 at the bottom. The child then uses the blowing component 4 to blow air onto the bottom of the small ball 3, causing the small ball 3 to rise along the step rods 2. The child can blow out different flow rates of air through the blowing component 4, resulting in the small ball 3 rising at different speeds and along different paths along the step rods 2. This helps the child understand concepts such as airflow, wind speed, and pressure. The overall design is simple, easy to assemble and disassemble, and therefore easy to carry.

[0023] It should be further explained that the support assembly 1 includes a side plate 101, a stepped groove 102 formed on one side of the side plate 101, and a plurality of connecting holes 103 formed on the top side of the side plate 101; the side plate 101 is used for support, and the connecting holes 103 are used for connecting the stepped rod 2.

[0024] Furthermore, the stepped rod 2 includes a connecting rod 201 and hemispherical protrusions 202 connected to both ends of the connecting rod 201. The two hemispherical protrusions 202 are integrally formed with the connecting rod 201. One end of each connecting rod 201 is inserted into the interior of the corresponding connecting hole 103, and each connecting rod 201 and the corresponding connecting hole 103 are interference fit. By inserting the hemispherical protrusions 202 at the end of the connecting rod 201 into the connecting hole 103, the connecting rod 201 and the connecting hole 103 are stably connected, thereby making the stepped rod 2 and the side plate 101 stably connected. This completes the splicing of the stepped rod 2 and the support assembly 1, forming an experimental mechanism.

[0025] It should be noted that the blowing assembly 4 is composed of an L-shaped blowing tube 401, wherein one end of the L-shaped blowing tube 401 is set as the blowing end 402, and the other end of the L-shaped blowing tube 401 is set as the air outlet end 403; the child puts the blowing end 402 on the L-shaped blowing tube 401 in his mouth to blow air, so that air is discharged from the air outlet end 403, thereby blowing the ball 3.

[0026] Furthermore, the overall outline of the side plate 101 is set as a right triangle, and the stepped groove 102 is opened on the inclined side of the side plate 101; the right triangle side plate 101 is easy to be placed stably on the placement plane.

[0027] Furthermore, the distribution contour of the multiple connecting holes 103 changes with the distribution contour of the stepped groove 102, and the ball 3 rests between two adjacent connecting rods 201; this facilitates the connection of the stepped rod 2 with the side plate 101, so that the stepped rod 2 forms a stepped distribution, thereby making it easier for the ball 3 to rise under the blowing of the air blowing component 4.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
