[0057] refer to Figure 1 and Figures 3-5 Some embodiments of this application provide a gun barrel device, which includes a gun barrel 1, a smoke-generating component 2, and a light-emitting component 3. The smoke-generating component 2 includes a receiving chamber 21 disposed in the gun barrel 1 and a smoke-generating element 22. The smoke-generating element 22 includes a smoke-generating working part 220. The receiving chamber 21 is configured to contain smoke-generating material and supply smoke-generating material to the smoke-generating working part 220, which is configured to atomize the smoke-generating material to generate smoke. The light-emitting component 3 includes a light-emitting lamp 31 disposed in the gun barrel 1. Therefore, the gun barrel 1 is equipped with a light-emitting component 3 and a smoke-generating element 22. Smoke can be generated by atomizing the smoke-generating material through the smoke-generating working part 220, and a light-emitting effect can be provided by the light-emitting lamp 31 of the light-emitting component 3. Thus, the gun barrel device of this application has the effects of emitting light and smoke, which can enhance the fun and experience.

[0058] In some implementations, reference Figure 3 , Figure 4 There are multiple light-emitting lamps 31, which are arranged around the barrel 1. The light-emitting lamps 31 are color-changing LEDs, which can change to different colors, making them more playable and visually stunning. Specifically, there can be three light-emitting lamps 31, which are arranged around the mouth of the barrel 1 and emit light along the direction of the mouth of the barrel 1.

[0059] For the specific structure of the smoke generator 22, please refer to [reference needed]. Figure 5 and Figure 8In some embodiments, the smoke-generating element 22 includes an oil-guiding core wire 221 and an atomizing element 222. The oil-guiding core wire 221 is connected to the receiving chamber 21 and is configured to absorb smoke-generating material. The atomizing element 222 includes at least one of an electric heating element and an ultrasonic atomizing plate. At least one of the electric heating element and the ultrasonic atomizing plate cooperates with the oil-guiding core wire 221 to form a smoke-generating working section 220 for atomizing the smoke-generating material in the oil-guiding core wire 221 to produce smoke. Preferably, in some embodiments, the atomizing element 222 is an electric heating element, which can be an electric heating wire wound on the oil-guiding core wire 221; the oil-guiding core wire 221 can be a cotton thread or the like with the ability to absorb e-liquid. When smoke generation is required, the atomizing element 222 is energized, and the smoke-generating material present in the smoke-generating working section 220 formed with the oil-guiding core wire 221 is atomized to produce smoke. In some embodiments, the smoke-generating material can be existing atomizable e-liquid.

[0060] In some implementations, reference Figure 4 , Figure 7 and Figure 12 The gun barrel assembly also includes a circuit board 4 and a switch 5. The smoke generator 22 and the light source 31 are electrically connected to the circuit board 4; the switch 5 is also electrically connected to the circuit board 4. The switch 5 is configured to synchronously trigger or deactivate the smoke generator 22 and the light source 31, thus controlling the smoke generator 22 and the light source 31 via the switch 5 and the circuit board 4. In some embodiments, the switch 5 can be a button, an infrared switch 5 trigger with a transmitter and a receiver. The transmitter of the infrared switch 5 trigger can emit infrared light radially along the barrel 1. A perforation can be formed on the side wall of the barrel 1 to allow the infrared light to pass through, and the emitted infrared light is received by the receiver. When the gun barrel of this application is mounted on a toy gun, and a bullet is fired from the gun barrel assembly, the bullet passes through and blocks the infrared light within the barrel 1, causing the receiver to temporarily lose the infrared light, thereby triggering the circuit board 4 to control the smoke generator 22 and trigger the light source 31 to illuminate. When the triggering structure is a button (such as the trigger of a toy gun), the user can press the button to trigger the circuit board 4 to control the smoke generator 22 to work and trigger the light lamp 31 to light up.

[0061] In some implementations, reference Figure 4 , Figure 5 as well as Figures 9-11 A slot 11 is formed on the outer side of the barrel 1, and the smoke-generating component 2 is inserted into the slot 11. The installation is convenient and the smoke-generating component 2 can be fixed relatively stably on the outer side of the barrel 1.

[0062] Further, refer to Figure 5 , Figure 7 and Figures 9-11In some embodiments, the barrel assembly further includes a first conductive element 6 and a second conductive element 7. The first conductive element 6 is disposed on the barrel 1 and electrically connected to the circuit board 4; the second conductive element 7 is disposed on the barrel 1 and electrically connected to the circuit board 4; wherein, the smoke generator 22 has a first guide pin 223 and a second guide pin 224. When the smoke generator 2 is inserted into the slot portion 11, the first guide pin 223 is connected to the first conductive element 6, and the second conductive element 7 is connected to the second guide pin 224, so that the smoke generator 22 is electrically connected to the circuit board 4, thereby forming a plug-in engagement, and electrically connecting the smoke generator 22 to the circuit board 4.

[0063] In some implementations... Figures 3-7 The containment chamber 21 and the smoke generator 22 are arranged around the barrel 1. The side wall of the barrel 1 is provided with a smoke hole 12. The smoke generator 220 faces or passes through the smoke hole 12. The smoke generated by the smoke generator 220 can enter the barrel 1 more easily through the smoke hole 12 and then be discharged from the barrel 1, better simulating the effect of smoke coming out of the barrel 1 when firing a bullet.

[0064] In some implementations... Figures 3-5 , Figures 9-11 The barrel assembly also includes a blower 8. The blower 8 is located outside the barrel 1, and the smoke-generating working part 220 is located in the air outlet path of the blower 8. The blower 8 is configured to blow air into the interior of the barrel 1 through the smoke hole 12, thereby further accelerating the diffusion of smoke and its rapid discharge from the nozzle of the barrel 1, so as to better simulate the effect of rapid smoke emission from the nozzle of the barrel 1 when firing a bullet.

[0065] To centralize airflow. In some implementations, refer to Figures 9-11 The blower 8 includes an air outlet 81, and the gun barrel assembly also includes an air guide duct 13. One end of the air guide duct 13 is connected to the air outlet 81, and the other end of the air guide duct 13 is connected to the smoke hole 12. By adding the air guide duct 13, the air outlet 81 of the blower 8 blows air into the air guide duct 13, and the air is concentrated and guided to the smoke hole 12 by the air guide duct 13. At the same time, since the smoke generating part 220 is located on the air outlet path of the blower 8, the smoke generated by the smoke generating part 220 can be quickly blown into the interior of the gun barrel 1 through the smoke hole 12, and then emerges from the nozzle of the gun barrel 1.

[0066] In some implementations, reference Figure 6 The air duct 13 and the gun barrel 1 are integrally formed, which can reduce the number of parts and reduce the assembly process steps.

[0067] In some implementations, reference Figure 5 , Figure 8 , Figure 9The containment chamber 21 contains a sealed oil storage cavity 211, which stores e-liquid. The outer wall of the containment chamber 21 is recessed to form a groove 212, which is separated from the oil storage cavity 211. The groove 212 covers the smoke hole 12, and the smoke generating unit 220 is located in the groove 212. The air duct 13 is connected to the groove 212, thus forming a connected channel between the smoke hole 12, the groove 212, and the air duct 13. The air duct 13 is connected to the groove 212 and blows air into the groove 212. The smoke generated by the smoke generating unit 220 in the groove 212 is first concentrated in the groove 212, and then blown further into the smoke hole 12 and the interior of the barrel 1 by the air duct, and finally discharged from the nozzle of the barrel 1.

[0068] In some embodiments, the barrel assembly may also include a battery electrically connected to the circuit board 4, thereby providing power to at least one of the fan 8, the light lamp 31, and the atomizing element 222.

[0069] refer to Figures 1-3 In some embodiments, the barrel assembly further includes a housing 9, which includes a first end cap 91, a second end cap 92, and a sleeve 93 with openings at both ends. The barrel 1 is coaxially and fixedly connected to the second end cap 92. The barrel 1, the smoke-generating component 2, and the light-emitting component 3 are inserted through the sleeve 93. The second end cap 92 is placed on one end of the sleeve 93, and the first end cap 91 is placed on the other end of the sleeve 93. The overall structure is assembled, and the sleeve 93 can play a protective role.

[0070] Some embodiments of this application also provide a toy gun that includes the barrel device of any of the above embodiments.

[0071] In some embodiments, the barrel assembly may be the entire barrel 1 of a toy gun, with the smoke-generating component 2 and the light-emitting component 3 disposed on the barrel 1.

[0072] In other embodiments, the barrel assembly may be designed similarly to a silencer. The barrel assembly may be a separate design, and in use, the barrel assembly is inserted in series into one end of the muzzle of the toy gun.

[0073] In some embodiments, the circuit board 4 may also include a first plug-in terminal 41 and a second plug-in terminal 42. The muzzle of the toy gun may have a third plug-in terminal and a fourth plug-in terminal (not shown in the figure). The toy gun may also include a battery, with its two ends connected to the third plug-in terminal and the fourth plug-in terminal respectively. In use, the barrel assembly is connected in series to the muzzle of the toy gun. The first plug-in terminal 41 and the third plug-in terminal are connected. The second plug-in terminal 42 and the fourth plug-in terminal are connected, thereby connecting the battery to the circuit board 4, which can provide power to the smoke-generating component 2 and the light-emitting component 3.

[0074] Finally, it should be noted that the technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
