[0033] In the description of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise clearly defined. In addition, unless otherwise clearly defined and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.

[0035] The utility model provides a technical solution: a popular science interactive air cannon device, comprising a barrel 1 and a smoke machine 2, the barrel 1 is hollow inside and has openings at both ends, the end of the barrel 1 close to the user is sealed by a sealing component 3, the sealing component 3 is elastic, the sealing component 3 has a stretching plate 4 running through its body, a first buckle 5 is provided on a side of the stretching plate 4 facing the inside of the barrel 1, a plurality of second buckles 6 are provided on an end of the inner side wall of the barrel 1 away from the user, a rope (not shown) is connected between each second buckle 6 and the first buckle 5, and the smoke outlet of the smoke machine 2 is connected to the inside of the barrel 1 through a connecting component.

[0036] For details, see Figures 1 to 3The barrel 1 near the end of the user is equipped with an elastic sealing component 3, which includes but is not limited to Lycra cotton cloth, polyester cloth, spandex cloth, etc., which can produce a certain deformation when the stretching plate 4 is pulled. A plurality of second buckles 6 are installed near the launch port on the inner side wall of the barrel 1, and a first buckle 5 is installed on the inner side of the stretching plate 4. The first buckle 5 is connected to each second buckle 6 by a rope, and the smoke outlet of the smoke machine 2 is connected to the inside of the barrel 1 by installing a connecting component, and the connecting component includes but is not limited to a conduit, a pipe, etc. Among them, the principle of the air cannon is to utilize the principle of aerodynamics, the working medium is air, and a differential pressure device and a quick exhaust valve that can realize automatic control can instantly convert air pressure energy into air jet kinetic energy, which can generate a strong impact force. Based on this principle, when the interior of the barrel 1 of the device is filled with smoke sprayed by the smoke machine 2, the user can pull the stretch plate 4 to make the internal smoke of the barrel 1 flow toward the user (i.e., form a differential pressure). When the user releases the stretch plate 4, the sealing component 3 rebounds quickly, so that the internal smoke of the barrel 1 is sprayed toward the launch port to form an air cannon (i.e., quickly exhaust and convert the air pressure energy into air jet kinetic energy). The overall structure of the air cannon device is simple, and it is easy to assemble and disassemble, which is conducive to popular science teaching. In addition, when used with the smoke machine 2, a visible "cannonball" can be formed, and the launch effect is better, which is conducive to demonstration.

[0037] As an optional implementation, in some embodiments, the barrel 1 includes a plurality of barrels 7 with different diameters, the diameters of the barrels 7 gradually decrease in the direction away from the user, and two adjacent barrels 7 are connected by an annular baffle 8, which shields the gap between the two adjacent barrels 7.

[0038] For details, see again Figure 3 The user can increase the firing distance of the air cannon by adding multiple cylinders 7 according to the requirements of the usage scenario. For example, in some larger sites, if the air cannon needs to be fired farther, the number of cylinders 7 can be appropriately increased. At the same time, in order to avoid the air cannon being too powerful, the power of the air cannon can be appropriately reduced by reducing the diameter of the cylinder 7.

[0039] In the above embodiment, further, a support seat 9 is included, on which a support frame 10 is arranged, and the support frame 10 is fixedly connected to the outer side surfaces of the plurality of cylinders 7 through a support rod 11. Figure 2 The air cannon device is stabilized by a plurality of supporting components, which greatly improves the stability of the barrel 1 and prevents the barrel 1 from moving due to recoil when firing the air cannon. The support seat 9 is a rectangular frame (the frame design can save manufacturing materials), and the support frame 10 is a trapezoid (the trapezoidal structure has high strength and high stability).

[0040] In the above embodiment, further, a support plate 12 is provided on the support seat 9 near the user, the fog machine 2 is placed on the support plate 12, a smoke inlet is provided on the cylinder 7 near the user, and a smoke outlet of the fog machine 2 is connected to a conduit 13, which passes through the smoke inlet and enters the interior of the cylinder 7. Figure 2 The support plate 12 is installed in the support seat 9 of the rectangular frame, and the support plate 12 is close to the user, so that the smoke generated by the smoke machine 2 can better enter the largest cylinder 7. At the same time, the length of the conduit 13 can be shortened, making the layout of the entire device more beautiful.

[0041] As an optional embodiment, in some embodiments, it also includes a base 14, the interior of the base 14 is hollow, and at least one fixed seat 15 is arranged inside the base 14. A hydraulic press 16 is arranged in the fixed seat 15, and the output end of the hydraulic press 16 is connected to a lifting rod 17, and the other end of the lifting rod 17 is fixedly connected to the upper cover plate 18 of the base 14. The support seat 9 is arranged on the upper cover plate 18 of the base 14, and a button switch (not shown in the figure) is arranged on the outer side surface of the base 14. The button switch is electrically connected to the control panel of the hydraulic press 16. Pressing the button switch drives the output end of the hydraulic press 16 to move up and down, so that the lifting rod 17 is raised or lowered.

[0042] For details, see Figure 4 and Figure 5 The air cannon device can also be height-adjusted according to actual usage. In this way, when it needs to be raised or lowered, the user can press the button switch to start the hydraulic press 16 to raise or lower the lifting rod 17, thereby raising or lowering the upper cover 18, and then raising or lowering the height of the barrel 1 on the support seat 9.

[0043] As an optional implementation, in some embodiments, a first handle 19 is provided on the side of the stretch plate 4 facing the user. Figure 2 The first handle 19 is installed to facilitate the user to pull the stretching plate 4.

[0044] As an optional implementation, in some embodiments, a second handle 20 is provided on one side of the base 14. Figure 2 The second handle 20 is installed to facilitate the user to pull the base 14.

[0045] As an optional implementation, in some embodiments, the lower surface of the base 14 is provided with a universal wheel 21, and the universal wheel 21 is provided with a direction lock 22. Figure 2 The universal wheels 21 are installed to facilitate the base 14 to have better steering ability when moving, and the direction lock 22 can provide better stability when the base 14 needs to be fixed.

[0046] As an optional implementation, in some embodiments, a fog machine controller (not shown) is further included, and a control chip of the fog machine controller is connected to the controller signal of the fog machine 2. The fog machine controller facilitates the user to remotely control the fog machine 2 to spray, so that the amount of fog inside the barrel 1 can be kept at all times, so that each firing effect of the air cannon is relatively good. In addition, the fog machine controller can be connected to the fog machine 2 by wire or wireless, and can be adjusted according to the use requirements to meet the remote control.

[0047] As an optional implementation, in some embodiments, a light strip (not shown) is provided on the outer side of the annular baffle 8. The installation of the light strip can facilitate the user to use the air cannon device normally in a relatively dark environment, and can also serve as a decoration to make the appearance of the air cannon device more beautiful.
