Description

Technical Field

[0001] The invention relates to the technical field of air cannons, and in particular to a handheld air cannon. Background Art

[0002] The air cannon is based on the principles of aerodynamics, using air pressure differences to allow air to flow rapidly to generate wave energy. In order to facilitate the observation of the vortex ring state generated by the air cannon, smoke is filled in the air cannon as a medium. Existing smoke-generating devices are separated from the air cannon. If solid smoke cakes are used to generate smoke, the solid smoke cakes need to be ignited before use, and then thrown into the air cannon. After use, the smoke cakes need to be extinguished in time. If smoke oil is used to generate smoke, an external smoke machine is required to fill the air cannon with smoke; the former has the problem of complex operation, and the ignited smoke cakes have certain safety hazards. The latter is suitable for larger air cannons, and must be used near the smoke charger, resulting in a poor gaming experience. Summary of the invention

[0003] The purpose of the present invention is to provide a handheld air cannon to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a handheld air cannon, comprising a handle, a shell fixedly connected to the handle, a tarpaulin installed on the shell, a receiving groove opened in the handle, a control panel fixedly connected in the receiving groove, the control panel electrically connected to a key panel, the key panel electrically connected to an electromagnetic pump and a smoke bin, and the key panel, the electromagnetic pump and the smoke bin are all fixedly connected in the receiving groove, the output end of the electromagnetic pump is conductively connected to the input end of the smoke bin, and the output end of the smoke bin is arranged in the shell.

[0005] Preferably, a rib plate is provided in the accommodating groove, a first mounting hole is provided in the accommodating groove, and a second mounting hole is provided on the shell.

[0006] Preferably, the control board is electrically connected to a battery, and the battery is fixedly connected in the receiving slot.

[0007] Preferably, a power switch and a start button are electrically connected to the keypad.

[0008] Preferably, a mounting groove is provided on the shell, a fixing ring is clamped and fixed in the mounting groove, and the fixing ring is sleeved in the tarpaulin, and the tarpaulin is squeezed and fixed in the mounting groove through the fixing ring.

[0009] Preferably, a limiting flange is provided in the installation groove, a plurality of elastic blocks are evenly distributed on the fixing ring, and the elastic blocks are clamped on the limiting flange.

[0010] Preferably, a through hole is provided on the shell at a position corresponding to the tarpaulin.

[0011] The handheld air cannon provided by the present invention has the advantages that: the present invention integrates a smoke bin as a smoke-generating module into the air cannon circuit system, utilizes the smoke bin to generate smoke, and delivers the smoke into the shell through the airflow generated by the electromagnetic pump, thereby realizing automatic smoke filling. Compared with the method of using an external smoke filling device to fill smoke, this design is conducive to the miniaturization and portability of the air cannon, is conducive to improving the gaming experience, and is safer and more convenient than smoke cakes.
