Referring to fig. 1 to 3, the color paper launcher 10 according to the preferred embodiment of the present invention includes a combustion chamber 100, a gas supply assembly 200, a gun barrel 300 and a baffle 400. Wherein:

the combustion chamber 100 is formed with a space in which a combustible gas is burned. The gas supply assembly 200 is in communication with the combustion chamber 100 and is configured to introduce a combustible gas into the combustion chamber 100. The combustion of the combustible gas in the combustion chamber 100 produces high pressure gas. The combustible gas is generally common and cheap butane, and can also be acetylene, natural gas, liquefied gas, hydrogen and the like. The barrel 300 has a hollow cylindrical structure and communicates with the combustion chamber 100. Therefore, the high-pressure gas in the combustion chamber 100 can enter into the barrel 300. The flap 400 is provided in the barrel 300. The baffle 400 is provided with a plurality of through holes 410 for allowing gas to pass through. Moreover, when the color paper 20 is loaded into the barrel 300, the color paper 20 can be carried on the baffle 400 without falling into the combustion chamber 100. Meanwhile, high-pressure air can pass through the baffle 400 through the through hole 410, so that the color paper 20 is blown up.

The high-pressure gas is used as a launching power to spray the color paper 20 out of the gun barrel 300. The combustible gas may be stored by a portable gas canister 30 and connected to the gas supply assembly 200 when needed. It can be seen that the color paper emitting device 10 does not need a compressor for emitting the color paper 20, so the overall volume and weight are reduced. Moreover, on the premise of sufficient air supply, the air supply assembly 200 can continuously supply air, and the color paper 20 can be loaded again after each shooting, so that the time interval between two shooting is short.

In addition, waste gas generated after combustion of common combustible gas is water vapor, carbon dioxide and the like, and the pollution to the environment is far less than that of gunpowder combustion, so that the environment is protected and meets the requirements.

The combustion chamber 100 may be a cavity structure formed of a high temperature resistant material such as stainless steel or ceramic. In order to ignite the combustible gas, an ignition needle 110 is also generally provided in the combustion chamber 100. The ignition needle 110 is electrically connected with the boosting module, and the main board controls the boosting module to boost when the conditions are met, so that the ignition needle 110 discharges. The combustible gas needs to be mixed with air (oxygen) in the combustion chamber 100 to smoothly perform combustion. Specifically, an auxiliary intake line may be provided to charge the combustion chamber 100 with air or oxygen.

Referring to fig. 3 again, in the present embodiment, the color paper emitting device 100 further includes a mixing tube 500, one end of the mixing tube 500 is communicated with the air supply assembly 200, the other end is communicated with the combustion chamber 100, and the side wall of the mixing tube 500 is provided with an air suction opening 510. That is, the gas supply assembly 200 is communicated with the combustion chamber 100 through the mixing pipe 500, and the combustible gas passes through the mixing pipe 500 before entering the combustion chamber 100.

The mixing tube 500 is generally a metal tubular structure. According to the venturi principle, an increase in the fluid flow rate is accompanied by a decrease in the fluid pressure. When the combustible gas supplied from the gas supply assembly 200 flows through the mixing pipe 500, a negative pressure is generated inside the mixing pipe 500 due to a relatively high gas flow rate inside the mixing pipe. At this time, the external air may enter the mixing pipe 500 through the air inlet 510, and the mixing with the combustible gas is automatically completed.

Therefore, the color paper launching device 10 only needs one set of gas supply assembly 200 to provide combustible gas, and no additional oxygen tank or auxiliary gas inlet pipeline is needed. When the combustible gas passes through the mixing tube 500, the external air is driven into the mixing tube 500 through the air suction opening 510 and is automatically mixed with the combustible gas. Therefore, the color paper emitting device 10 has a simpler overall structure, lighter weight and more convenient carrying.

Further, in the present embodiment, the plurality of suction ports 510 are spaced apart in the circumferential direction of the mixing pipe 500. Accordingly, the external air may be gushed into the mixing tube 500 along the circumference of the mixing tube 500, thereby making the air and the combustible gas mixed more uniformly, contributing to sufficient combustion of the combustible gas in the combustion chamber 100.

Referring to fig. 1 again, in the present embodiment, a rotating shaft 120 is disposed on the combustion chamber 100. The rotary shaft 120 may be provided on a side wall of the combustion chamber 100 or may penetrate the combustion chamber 100. The combustion chamber 100 can be mounted on a support or the like by rotating the shaft 120. The rotation of the rotary shaft 120 rotates the combustion chamber 100 and the barrel 300. Therefore, the emitting angle of the color paper can be adjusted accordingly.

The gas supply assembly 200 includes a gas inlet pipe 210, a nozzle 220, and a bottle opener 230. The nozzle 220 and the bottle opener 230 are connected to the nozzle 220 at both ends of the air inlet pipe 210, respectively. The bottle opener 230 is used to fix and open the gas tank 30. When not in use, the gas tank 30 storing the combustible gas may be separated from the gas supply assembly 200. Thus, the color paper emitting device 10 is more convenient to transport. While the tank 30 for storing combustible gas is readily available, for example, butane gas tanks are sold in general supermarkets. When in use, the gas tank 30 is abutted with the bottle opener 230, and the combustible gas can be sprayed from the nozzle 220 to the combustion chamber 100 through the gas inlet pipe 210. Further, the nozzle 220 has a small diameter, so that the flow rate of the combustible gas can be increased.

Specifically, the mixing tube 500 is configured to interface with the nozzle 220. Because the nozzle 220 can promote the velocity of flow of combustible gas, so in the combustible gas gets into the mixing tube 500 through the nozzle 220, can make and form stronger negative pressure in the mixing tube 500, and then promote the air input of the interior air of mixing tube 500.

Further, in the present embodiment, the air supply assembly 200 includes an electromagnetic valve 240 disposed on the air inlet pipe 210 and used for controlling the on/off of the air inlet pipe 210.

The electromagnetic valve 240 can be electrically connected to a corresponding main board, and the main board controls the electromagnetic valve 240 to open or close according to a preset program or a control instruction, so as to control the amount of the combustible gas entering the combustion chamber 100, and further change the spraying height of the color paper 20 by changing the on-off time of the electromagnetic valve 240, thereby achieving different effects. Specifically, the longer the solenoid valve 240 is opened, the more combustible gas is introduced into the combustion chamber 100, and ultimately the higher the spray height of the color paper 20.

Further, in the present embodiment, the air supply assembly 200 further includes a pressure sensor 250 for detecting an intake pressure in the intake pipe 210 and a reminder (not shown), wherein the reminder is turned on when the intake pressure is smaller than a preset pressure.

The reminder may be a vibrator, a buzzer, or a display screen. The intake pressure detected by the pressure sensor 250 may reflect the pressure value within the gas tank 30. When the air inlet pressure is lower than the preset pressure, the combustible gas in the air tank 30 is about to be exhausted, so that the reminder is started, and a user can be reminded of replacing the air tank 30 in time.

Further, in this embodiment, the gas supply assembly 200 further includes a check valve 260 disposed on the gas inlet pipe 210, and the check valve 260 allows the combustible gas to flow toward the nozzle 220. The check valve 260 can prevent the air flow from being guided into the air tank 30, and prevent backfire, thereby effectively reducing potential safety hazards.

The barrel 300 is generally formed of a stainless steel material and may have a hollow cylindrical configuration. In this embodiment, barrel 300 comprises two parts, a body section 310 and an extension section 320. The main body section 310 is communicated with the combustion chamber 100, and the extension section 320 is sleeved on the main body section 310. Wherein, the inner wall of the extension section 320 near one end of the main body section 310 forms an annular step (not shown), and the baffle 400 is supported against the annular step and clamped on the surface of the main body section 310 against the annular step. The gun barrel 300 is provided in two parts, which facilitates installation of the baffle 400.

The baffle 400 is also made of a high temperature resistant material, generally stainless steel, so that it has high mechanical strength while being resistant to high temperature. The plurality of through holes 410 may be uniformly distributed in the baffle 400. The aperture of the through hole 410 is small, so that the color paper 20 can be prevented from passing through, and the baffle 400 is equivalent to a filter screen.

In this embodiment, the flap 400 is located at the end of the barrel 300 remote from the combustion chamber 100. On the one hand, the baffle 400 is closer to the exit of the barrel 300, which further facilitates rapid loading of the color paper 20. On the other hand, the color paper 20 is loaded and is located far from the combustion chamber 100. Therefore, the combustible gas that is not sufficiently combusted in the combustion chamber 100 will have sufficient time to sufficiently combust in the barrel 300 before contacting the color paper 20. Thus, when the high-pressure gas emits the color paper 20, no flame will be generated, thereby preventing the color paper 20 from being ignited.

When the color paper launching device 10 is used, the color paper 20 is firstly loaded into the gun barrel 300 and is supported on the baffle 400, and combustible gas is filled into the combustion chamber 100 through the gas supply assembly 200. The combustible gas is combusted in the combustion chamber 100 to form high-pressure gas, and the high-pressure gas is used as launching power to spray the color paper 20 from the gun barrel 300. As can be seen, the gas supply assembly 200 can supply gas to the combustion chamber 100 through the portable gas canister 30 without using a compressor, so that the overall volume and weight are reduced. Moreover, the air supply assembly 200 can continuously supply air, and the color paper 20 can be loaded again after each shooting, so that the time interval is short. Therefore, the color paper emitting device 100 is more convenient to use.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
