Description

Technical Field

[0001] This utility model relates to the technical field of air vortex cannons, and in particular to an air vortex cannon and an adjustable air vortex cannon device. Background Technology

[0002] Air vortex guns primarily involve fluid mechanics and aerodynamics. These guns utilize the vortex energy generated by high-speed jets of air to propel projectiles or targets. Specifically, air vortex guns generate high-speed airflow through high-pressure gases or high-pressure gases produced by gunpowder combustion. This airflow forms vortices within the barrel, and the powerful energy generated by these vortices propels the projectile or target at high speed, thus achieving the firing effect. Furthermore, the formation and changes in these vortices can be controlled by adjusting factors such as the speed and direction of the airflow, thereby achieving different trajectories and speeds for the projectile or target.

Detailed Implementation

[0031] 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.

[0032] The purpose of this invention is to provide an air vortex cannon and an adjustable air vortex cannon device to solve the problems existing in the prior art. This allows the air vortex cannon to not use an air compressor or combustible gas as a power source, and it has a simple structure, is safe and reliable, and can be used in a variety of scenarios.

[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figures 9 to 11 As shown, this embodiment provides an air vortex cannon, including a frame 1, a translation mechanism, and a compressed gas chamber 2. The translation mechanism is mounted on the frame 1. The compressed gas chamber 2 is an elastic cavity with variable volume. One end of the elastic cavity is closed, and the other end has an air port 19. The area of ​​the air port 19 is smaller than the cross-sectional area of ​​the elastic cavity. The closed end of the compressed gas chamber 2 is connected to the translation mechanism, and the air port end is fixed to the frame 1. This embodiment does not use an air compressor or combustible gas, making it safe and reliable. The air port 19 is preferably oriented horizontally.

[0036] As an optional solution, in this embodiment, the closed end of the compressed gas chamber 2 is detachably connected to the translation mechanism, and an acceleration component is connected to the closed end of the compressed gas chamber 2. The acceleration component can accelerate the reduction of the volume of the compressed gas chamber 2, and rapidly compress it before the gas flows out. The acceleration component can also be replaced by a spring, elastic steel, cylinder, hydraulic cylinder, electric push rod, or other device that can push the closed end of the compressed gas chamber 2 forward.

[0037] As an optional solution, the acceleration component in this embodiment includes an elastic element 4, a guide rod 3, and a slider 5. The guide rod 3 is arranged parallel to the frame 1 along the movement direction of the compressed gas chamber 2. One end of the elastic element 4 is fixed to the frame 1, and the other end is fixed to the slider 5. The slider 5 is slidably arranged on the guide rod 3 and connected to the closed end of the compressed gas chamber 2. When the volume of the compressed gas chamber 2 increases, the elastic element 4 is in a stretched state. When the volume of the compressed gas chamber 2 decreases, the elastic element 4 is in a rebound state. The elastic force of the elastic element 4 accelerates the rebound of the bottom cover 16 of the compressed gas chamber 2, quickly compressing the gas in the compressed gas chamber 2, which facilitates the formation of an air vortex. The specific principle behind the vortex effect generated when compressed air passes through the air inlet 19 is as follows: When the compressed air in the compressed gas chamber 2 is rapidly ejected through the circular air inlet 19, there is a velocity difference between it and the air outside the air inlet 19. According to Bernoulli's principle, the pressure of a fluid is inversely proportional to its velocity. The low-speed air (the air outside the air inlet 19) will be driven to tumble by the high-speed air (the air ejected from the air inlet 19). When the airflow passes through the air inlet 19, a velocity difference will form a vortex at the edge of the air inlet 19, and there will be a vortex at every point on the circular edge of the air inlet 19. As a result, a relatively stable annular vortex can be formed near the air inlet 19.

[0038] As an optional solution, in this embodiment, the frame 1 is a cuboid frame. The surface of the frame can be covered with a shielding plate according to aesthetic requirements. The frame can be constructed using aluminum profiles and engineering plastics, but is not limited to the above materials. It can also be made of metal plates, angle irons, etc., or manufactured using sheet metal, stamping, injection molding, and other processes.

[0039] As an optional solution, in this embodiment, four sets of acceleration components are symmetrically arranged on the frame 1, or two sets can be symmetrically arranged. Two sliders 5 located on the same side of the frame 1 are grouped together, and a push rod 6 is connected to the two sliders 5 in the same group. The push rod 6 can abut against the closed end of the compressed gas chamber 2. In this embodiment, the compressed gas chamber 2 is a cylinder, and the spacing between the guide rods 3 on the same side is smaller than the diameter of the cylinder, so that the push rod 6 can be located behind the cylinder and can push the bottom cover 16 of the compressed gas chamber 2 to accelerate its rebound.

[0040] As an optional solution, in this embodiment, one end of the elastic element 4 is fixed to a fixed pulley 7, and the other end passes over another fixed pulley 7 and is connected to a movable pulley 8, so that the elastic element 4 is V-shaped, increasing the elastic force of the elastic element 4. The movable pulley 8 is connected to the slider 5. The elastic element 4 is preferably an elastic band. The elastic element 4 can be made of materials that can store elastic potential energy, such as latex rings, spandex, or spring steel. The slider 5 is preferably a linear bearing to achieve fast and smooth sliding.

[0041] As an optional solution, in this embodiment, a magnet 14 is provided on the bottom cover 16 of the compressed gas chamber 2, and an electromagnet 15 is provided on the pull rod 12 of the translation mechanism. The electromagnet 15 and the magnet 14 are positioned correspondingly. By controlling the energization and de-energization of the electromagnet 15, the connection and separation of the compressed gas chamber 2 and the translation mechanism can be realized. When the electromagnet 15 is energized, it can attract the magnet 14, thereby causing the pull rod 12 to move the compressed gas chamber 2 backward together. When the electromagnet 15 is de-energized, it can separate from the magnet 14, thereby causing the acceleration component to accelerate the compressed gas chamber 2 to rebound. The bottom cover 16 of the compressed gas chamber 2 is quickly reset under the pull of the elastic element 4 and compresses the air in the chamber. During this process, the compressed air will be ejected from the air port 19 on the panel 17 in the form of an air vortex. The magnet 14 can also be replaced with an iron plate.

[0042] As an optional solution, in this embodiment, the translation mechanism is symmetrically arranged on both sides of the frame 1. Alternatively, a design structure with a single motor and lead screw, or multiple motors and lead screws, can be adopted. The translation mechanism includes a lead screw 10, a motor 9, a sliding nut 11, and a pull rod 12. The lead screw 10 is rotatably mounted on the frame 1. A sliding nut 11 is connected to the lead screw 10, and a pull rod 12 is connected between two sliding nuts 11. The pull rod 12 is located behind the bottom cover 16 of the compressed gas chamber 2. The pull rod 12 is detachably connected to the bottom cover 16 of the compressed gas chamber 2. One end of the lead screw 10 is connected to the motor 9 through a sprocket and chain transmission mechanism 13 or a pulley and synchronous belt transmission mechanism. Two motors 9 are provided to provide sufficient power. Limit switches are provided on the frame 1, and the limit switches are located at both ends of each lead screw 10. The limit switches include photoelectric switches 28, mechanical limit switches, or magnetic switches. In this embodiment, the limit switch is a photoelectric switch 28, and the sliding nut 11 is provided with a light shield 29 that matches the photoelectric switch 28. The light shield 29 can trigger the photoelectric switch 28 to limit the movement of the pulling rod 12, so as to avoid the pulling rod 12 from colliding with the frame 1 when it moves, and increase the service life of the equipment. The translation mechanism can be replaced by an electric push rod, belt transmission mechanism, etc., which can generate more than 1000N of power, far exceeding the level of human driving. It can generate enough energy air vortex to meet the needs of interactive experience. Direct contact with the human body will have a clear airflow impact feeling.

[0043] As an optional solution, in this embodiment, the compressed gas chamber 2 includes a bottom cover 16, a panel 17, and a flexible sealing cylinder 18. The bottom cover 16 and the panel 17 are arranged opposite to each other and are sealed together by the flexible sealing cylinder 18. The panel 17 is provided with an air port 19, the area of ​​which is smaller than that of the panel 17. The shape of the air port 19 is circular to facilitate the formation of a stable vortex ring. The flexible sealing cylinder 18 is made of airtight fabric, flexible plastic, or corrugated pipe. In this embodiment, steel wire nylon cloth is used, but other soft, airtight, and wear-resistant materials can also be selected.

[0044] In this embodiment, there is a pressure difference between the inside and outside of the air inlet 19 and the diameter is suitable. The air inlet 19 can form a flow velocity difference, which can generate a vortex. The air inlet 19 in this embodiment is designed as a simple circle. A special kit can also be designed based on the Venturi tube to enhance the air mass. The diameter of the air inlet 19 is related to the airflow velocity. An appropriate diameter of the air inlet 19 can be selected according to the airflow velocity to generate an air vortex ring.

[0045] In this embodiment, the energization of the electromagnet 15 connects the pull rod 12 to the magnet 14 of the bottom cover 16. The slider 5 of the translation mechanism drives the pull rod 12 and the compressed gas chamber 2 to move backward along the frame 1. The volume of the compressed gas chamber 2 increases, and the power storage action is performed until the limit switch at the end of the lead screw 10 is triggered. The power storage is completed, and the control unit 30 can control the electromagnet 15 to be de-energized, that is, the electromagnet 15 on the pull rod 12 separates from the bottom cover 16. The compressed gas chamber 2 will rebound rapidly under the drive of the acceleration component, thereby compressing the air in the compressed gas chamber 2. The compressed air can form a flow velocity difference at the air port 19 and form an air vortex to be ejected.

[0046] Example 2

[0047] like Figures 1 to 8 As shown, this embodiment provides an adjustable air vortex cannon device, including the air vortex cannon, pitch mechanism, horizontal rotation mechanism, and control unit 30 described in Embodiment 1 above. The air vortex cannon is a mechanically driven type. A pitch mechanism is located at the bottom of the air vortex cannon and is connected to the horizontal rotation mechanism. The air vortex cannon, pitch mechanism, and horizontal rotation mechanism are all communicatively connected to the control unit 30. In this embodiment, the pitch mechanism and horizontal rotation mechanism are equivalent to a two-axis gimbal structure, directly mounted on a flat platform, allowing for free horizontal rotation and at least 90° pitch swing, enabling the firing of air vortex rings at any angle above the mounting surface. By controlling the forward and reverse rotation of the motor 9, the firing angle of the entire device in two dimensions can be controlled. The control unit 30 is connected to a power supply, which uses a safe low-voltage DC 24V power supply, ensuring safety, controllability, and powerful performance, making it convenient for interactive experiences in densely populated places such as science museums and amusement parks.

[0048] As an optional solution, in this embodiment, the pitch mechanism includes a base 20 and a telescopic mechanism 21. One side of the base 20 is hinged to the bottom side of the frame 1 of the air vortex gun. One end of the telescopic mechanism 21 is hinged to the middle of the base 20, and the other end is hinged to the side opposite to the hinged side of the frame 1. The base 20 and the frame 1 are hinged by a hinge 22. The base 20 is a frame with the same shape and size as the bottom of the frame 1. The telescopic mechanism 21 is a hydraulic rod, an electric push rod, or a pneumatic cylinder. Limit switches are installed at the top and bottom of the push rod of the telescopic mechanism 21 to facilitate limiting the telescopic mechanism 21. The limit switches and the telescopic mechanism 21 are all communicatively connected to the control unit 30.

[0049] As an optional solution, in this embodiment, the control unit 30 is located inside the control box. Both the control box and the ultrasonic ranging sensor 27 are mounted on the frame 1 of the air vortex cannon. The ultrasonic ranging sensor 27 is located behind the bottom cover 16 of the air vortex cannon and is used to detect the position of the bottom cover 16. The control box contains a nine-axis sensor and a temperature sensor, both of which are communicatively connected to the control unit 30. In this embodiment, both the control unit 30 and the ultrasonic ranging sensor 27 are located behind the frame 1 of the air vortex cannon. The nine-axis sensor consists of three core components: an accelerometer, a gyroscope, and a magnetometer. It is used to calculate the current attitude of the air vortex cannon. The accelerometer measures the acceleration changes of the object in three-dimensional space, providing basic data for attitude measurement; the gyroscope focuses on capturing angular velocity, accurately calculating angle changes by sensing the object's rotational speed; and the magnetometer uses the Earth's magnetic field to determine direction. These three sensors each perform their specific functions while working together to improve the stability and accuracy of the measurement. The temperature sensor measures the temperature inside the control box. Because the multiple motors and drive mechanisms inside the equipment generate a lot of heat during operation, and the operating speed of the equipment will be reduced when the ambient temperature is too high, the temperature sensor measures the temperature inside the control box in real time, which can prevent the motors and drive mechanisms from operating at high power in high-temperature environments and extend their service life.

[0050] As an optional solution, the horizontal rotation mechanism in this embodiment includes an external gear bearing turntable 24, a pinion, and a motor 9. A base plate 23 is disposed in the middle of the base 20, and the base plate 23 is rotatably connected to the external gear bearing turntable 24. The external gear bearing turntable 24 is located below the base plate 23. The rotating shaft of the motor 9 passes through the base plate 23 and is connected to the pinion 25. The motor 9 is fixedly disposed on the base plate 23, and the pinion 25 meshes with the external gear ring of the external gear bearing turntable 24. Two sets of pinion 25 and motor 9 are symmetrically arranged. The diameter of the external gear ring is larger than the diameter of the pinion 25, which facilitates the speed reduction adjustment of the motor 9. An electric slip ring 26 is disposed on the base plate 23. The inner ring of the external gear bearing turntable 24 is located at the center of the base 20. The motor 9 is a stepper motor, which can realize precise control of the position and speed of the motor 9, which facilitates precise control of the rotation angle of the air vortex gun. The stepper motor can be replaced by a DC motor, DC geared motor, brushless motor, brushless geared motor, servo motor, servo geared motor, or other similar equipment. The power supply and communication lines of the equipment on both sides of the base plate 23 can be connected through the slip ring 26. When the equipment rotates, the connection of the circuit can be guaranteed, avoiding the risk of the cable breaking due to tangling and twisting.

[0051] The adjustable air vortex cannon device in this embodiment incorporates sensors such as an accelerometer, angular velocity meter, gyroscope, ultrasonic rangefinder, temperature sensor, and limit switch. The control unit 30's circuitry is connected to multiple sensors, enabling precise determination of the device's current attitude and the relative positions of its components. This allows for closed-loop control and fully digital control of all components. The device can be connected to various control schemes, including remote control follow-up control, remote control button control, computer control, or other intelligent devices. Wireless communication of the control unit 30 can utilize radio frequency communication; wired communication can employ differential bus communication (485 communication), allowing multiple devices to be connected to the same communication line. Devices can be configured with different addresses; a control command will only respond when its address matches the device's address. One-to-one operation means a one-to-one correspondence between the control command and device address; one-to-many operation means multiple devices can be configured with the same address and respond synchronously. Alternatively, intelligent devices such as computers can be used to issue control commands with different addresses, thereby controlling multiple devices.

[0052] In this embodiment, the adjustable air vortex cannon device is designed based on Bernoulli's principle in air. It measures 60cm*50cm*50cm, has a small volume, and is easy to arrange and install. It does not fire any physical material, and there is no risk of electric shock or explosion if any component is damaged. The air vortex ring can automatically control and adjust the firing direction for contact interaction. Direct contact with the human body will produce a noticeable airflow impact sensation, enhancing the gaming experience. It can be deployed in densely populated places such as science museums and amusement parks.

[0053] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
