[0002] In stage performances, TV variety shows, and cultural tourism projects, rapid-fire smoke is often used to create special effects. This is usually achieved using a smoke machine or a carbon dioxide column machine. The speed and force of the smoke sprayed by the smoke machine cannot match the effect of the carbon dioxide column machine. While the effect of the carbon dioxide column machine is excellent, it requires a large bottle of carbon dioxide gas as the smoke medium. In addition to being inconvenient to transport and expensive, a large bottle of carbon dioxide can only be sprayed for a very short time. Utility Model Content

[0012] This invention, employing the aforementioned structure, utilizes a high-speed fan and a smoke jet pipe to pressurize the airflow, increasing the speed and intensity of the sprayed smoke, achieving the same spraying effect as a carbon dioxide column generator.

[0019] See Figure 1-3As shown, this utility model discloses a high-speed air column jet injector, comprising a columnar smoke jet pipe 1. A high-speed fan 2 is installed on one side of the air inlet end of the smoke jet pipe 1. A mist spraying component 3 is installed inside the smoke jet pipe 1, and the mist spraying component 3 is connected to an external smoke source. An airflow divider 4 is installed at the air outlet end of the smoke jet pipe 1. By pressurizing the smoke jet pipe with the high-speed airflow of the high-speed fan, the speed and force of the sprayed smoke are increased, achieving the same spraying effect as a carbon dioxide air column generator. Furthermore, this spraying method does not rely on large bottles of carbon dioxide gas as the smoke medium, which not only facilitates transportation and reduces costs, but also allows for a longer spraying time.
[0020] In this embodiment, the smoke jet pipe 1 is assembled from a left shell 1a and a right shell 1b that cooperate with each other; the smoke jet pipe 1 is composed of a guide section 1c, an aerosol mixing section 1d, and a jet section 1e arranged sequentially along the axial direction. The left and right shell assembly structure facilitates the installation of the spray assembly and airflow divider into the smoke jet pipe. The guide section is a funnel-shaped air inlet that opens outwards at the rear end of the smoke jet pipe, used to guide the airflow and provide initial pressurization. The jet section is a tapered spray nozzle at the front end of the smoke jet pipe, with a gradually decreasing diameter to further pressurize the smoke airflow.
[0021] The high-speed fan 2 is located at the intersection of the guide section 1c and the mist mixing section 1d, and the mist spraying component 3 is located in the mist mixing section 1d in front of the air outlet of the high-speed fan 2.
[0022] In this embodiment, the mist spraying assembly 3 includes a mounting bracket 3a fixed inside the smoke spray pipe 1, an atomizing bracket 3b for fixing the atomizing pipe is mounted on the mounting bracket 3a, and a smoke disperser 3c is mounted on the atomizing bracket 3b in front of the mist outlet of the atomizing pipe. The smoke output from the atomizing pipe is dispersed by the smoke disperser 3c and then mixed with the high-speed airflow blown by the high-speed fan 2 before being output. The smoke disperser disperses the smoke output from the atomizing pipe, making the smoke distribution uniform, preventing smoke molecules from agglomerating and increasing the weight of the smoke, and facilitating the high-speed airflow to carry the smoke out.
[0023] In this embodiment, the airflow divider 4 consists of a positioning ring 4a and dividing holes 4b arranged in a grid pattern within the positioning ring 4a; high-speed smoke is output after being divided by the dividing holes 4b. The airflow divider divides and disperses the spray airflow, improving the uniformity of the spray.
[0024] In this embodiment, a waterproof motor cover 5 is provided between the high-speed fan 2 and the mist spraying assembly 3. This waterproof motor cover prevents incompletely atomized e-liquid from dripping into the high-speed fan and affecting its operation.
[0025] See Figure 4As shown, a smoke generator of this utility model includes a housing 6, and a smoke generator 7 is provided inside the housing 6. The smoke generator can be any kind of smoke generator conventional in the art. This structure is not a technical point to be protected in this application, and will not be described in detail here.
[0026] The smoke generator 7 is connected to the oil storage tank via an oil inlet pipe. Any of the aforementioned high-speed air column injectors is installed inside the housing 6. The smoke outlet of the smoke generator 7 is connected to the atomizing tube 8, and the free end of the atomizing tube 8 passes through the smoke injection tube 1 and is fixed to the misting assembly 3. A drainage groove with several evenly distributed drainage holes at the bottom is provided on the housing below the high-speed air column injector to prevent incompletely atomized e-liquid from dripping and accumulating inside the housing, causing problems.
[0027] During operation, the e-liquid in the oil storage tank is atomized by the smoke generator and then transported to the aero-mist mixing section of the smoke jet pipe through the atomizing pipe. The smoke collides and disperses with the smoke disperser, and then mixes with the high-speed airflow blown out by the high-speed fan and blown towards the jet section. The high-speed smoke is separated by the dividing hole and then output as jet smoke.
[0028] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
