Description

Technical Field

[0001] The present invention relates to the technical field of toy manufacturing, and in particular to an object launcher device and a use method thereof. Background Art

[0002] For many years, toy projectiles have been popular with children of all ages. Typically, projectiles fire projectiles using solid fuel rocket engines. However, there are many dangers when using solid fuel engines. For example, in a solid fuel rocket device, once the fuel is ignited, it generally will not stop unless the entire fuel supply is exhausted.

[0003] Other launching devices, such as projectile launchers, use a pressure tank that contains pressurized air or water that is discharged through a nozzle as a method of propelling the projectile. However, because these types of launchers are fully pressurized, they generally cannot be removed from the launcher without completing the launch, and there is a risk that the pressurized container will explode. Summary of the invention

[0040] The present invention provides a Figure 1 The projectile launcher device shown in the embodiment of FIG. The object launcher device uses an aerosol spray device 13 containing a flammable liquid as a propellant to launch a launched object 15; the device includes a chamber 3 and a launch tube 1, the launch tube 1 has an open bottom end 9 and an open top end 4, and the open bottom end 9 of the launch tube 1 is fixedly connected to the opening in the chamber 3. It should be understood that the launch tube 1 has a substantially constant cross-section, and the open top end 4 of the launch tube 1 has a screen 2 (a blocking strip may also be used) thereon to prevent foreign matter and fuel from entering the launch tube 1.

[0041] The chamber 3 has a volume of at least one liter, and in one embodiment, it may have a conical top end 4 and a conical bottom end 9; the chamber 3 is located above the base 8 of the object launcher device; the chamber 3 has an input port 5, which is configured to be connected to an aerosol spray device 13, allowing the chamber 3 to be filled with a flammable liquid, thereby producing a mixture of air and atomized flammable liquid 14; the chamber 3 is also provided with a pressure reducing valve 12, which can prevent the chamber 3 from being over-pressurized.

[0042] In one embodiment, an air pump 11 is connected to the chamber 3 to pump air into the chamber 3, which may flush out old or burned propellant fuel.

[0043] The shape of the lower chamber, i.e. the conical bottom end 9, acts as an inverted bazooka, which amplifies the pressure, resulting in increased efficiency and the rocket or projectile rising; the shape of the upper chamber, i.e. the conical top end 4, consolidates the pressure by focusing it into an inverted funnel, which has a concentrating and amplifying effect, and can increase the pressure that causes the launched object to rise.

[0044] A spark gap 10 is disposed inside the chamber 3, and the spark gap 10 is connected to a spark power source 7, such as a power supply, by at least two wires 16; the wires 16 have a sufficient length to allow the spark power source 7 to maintain a safe distance, such as at least 3 feet, from the chamber 3 and the projected object 15. The spark power source 7 can be activated to trigger the spark gap 10 to ignite, for example, by using a switch or button.

[0045] The launched object 15 has a closed top end 4 and an open bottom end 9 and is shaped to fit over the launch tube 1 in a slidable manner.

[0046] In one embodiment, the activation device 6 may be in the form of a lever, for example; an aerosol spray device 13 containing a flammable liquid is included in the device so as to be manipulated in a controlled manner, and the aerosol spray device 13 fills the chamber 3 with the flammable liquid.

[0047] In one embodiment, the input port 5 configured to connect to the aerosol spray device 13 has a specially keyed nozzle; in this embodiment, the specially keyed nozzle will only connect to a specific aerosol spray device 13 .

[0048] In one embodiment, the combustible liquid consists of hydrotreated light distillates (petroleum), butane, hydrofluorocarbon 152a, propane, fragrance, isobutane, and cinnamamide.

[0049] In one embodiment, it can be Figure 2 Shown using Figure 1 An object launcher device, comprising:

[0050] If necessary, the step of removing the launched object 15 from the launch tube 1 (step 101);

[0051] pumping air into the chamber 3 using the air pump 11 (step 102) to expel some residual propellant, such as residual propellant from a previous launch or a failed launch or an aborted launch;

[0052] The launched object 15 is placed on the launch tube 1 (step 103);

[0053] spraying the flammable liquid in the aerosol spray device 13 into the chamber 3, for example by using the activation device 6 of the aerosol spray device, thereby generating a mixture of air and atomized flammable liquid 14 in the chamber 3 (step 104);

[0054] Point the object device and the launched object 15 in a direction other than downward (step 105);

[0055] Preferably, multiple chambers can be stacked separately and fueled separately, in which way the pressure and volume of the reaction can be greatly increased, thereby launching a launch object 15 with a larger payload.

[0056] The spark power source 7 may be activated by using a switch (step 106), thereby generating a spark across the spark gap 10. By this operation, the mixture of air and atomized flammable liquid 14 is ignited, causing a rapid expansion of the exhaust gas in the chamber 3. The exhaust gas then passes rapidly through the launch tube 1, causing the launched object 15 to move rapidly away from the object launcher device.

[0057] In one embodiment, Figure 1 The object launcher device also uses a device that can be used as Figure 3 The method shown is used to safely abort a launch and includes the following steps:

[0058] If there is a launched object 15, then remove the launched object 15 from the launch tube 1 (step 201);

[0059] Air is then pumped into the chamber 3 using the air pump 11 (step 202), thereby expelling residual or burned propellant, such as residual propellant from a previous launch or a failed launch or an aborted launch;

[0060] The launched object 15 is placed on the launch tube 1 (step 203);

[0061] spraying the flammable liquid from the aerosol spray device 13 into the chamber 3, for example by using the activation device 6 of the aerosol spray device, thereby generating a mixture of air and atomized flammable liquid 14 in the chamber 3;

[0062] To abort the launch attempt, the launched object 15 may be removed from the launch tube 1 (step 205).

[0063] Air may be pumped into the chamber 3 using the air pump 11 (step 206 ), thereby expelling the mixture of air and atomized flammable liquid 14 out of the chamber 3 .

[0064] The above-described apparatus and method for using the device provide for safe, reliable, repeatable and entertaining launching of objects.
