The following detailed description of embodiments of the invention refers to the accompanying drawings. It is to be understood that the preferred embodiments of the present invention are shown in the drawings only, and are not to be considered limiting of the scope of the invention. Various obvious modifications, changes and equivalents of the embodiments of the invention shown in the drawings can be made by those skilled in the art, and all of them are within the scope of the invention.

Fig. 1 shows a schematic view of the structure of a smoke generator device 100 included in a smoke screen generation system according to the present invention. As shown, the smoke generator device 100 has a smoke generator housing 110 with a pull handle 111 disposed on the smoke generator housing 110, the pull handle 111 allowing a user to hold the device. The smoker box 110 is further provided with a box air inlet 112, and air outside the smoker device 100 enters the inside of the smoker box 110 through the box air inlet 112.

A control panel 120 is also embedded in a suitable location of the smoke generator housing 110 to provide an interface for a user to control the smoke generator device 100. For example, as shown in the drawing, a plurality of buttons 121 are provided on the control panel 120 for control. Preferably, the buttons 121 are buttons with a self-locking function, so that the buttons can be set in a self-locking state during transportation or during non-use, so as to prevent misoperation caused by accidental touch and the like.

The various components of the smoke generator device 100 are housed within a smoke generator housing 110. Specifically, as shown, the smoke generator housing 110 includes a power and electronic control module 130, and the power and electronic control module 130 may include, for example, a battery to power the operation of the smoke generator device 100. The power and electronic control module 130 may also include, for example, control circuitry to control the operation of the various components of the smoke generator device 100 and other parts of the smoke screen generation system.

A fuel tank 140 is included in the smoker box 110, the fuel tank 140 supplying fuel to a turbojet engine 160 as a power unit to power the turbojet engine 160. Fuel is supplied to the turbojet engine 160 through a fuel line 142 connected between the fuel tank 140 and the turbojet engine 160. Preferably, a fuel pump 141 is mounted in the fuel line 142 to assist in supplying fuel from the fuel tank 140 to the turbojet engine 160. Thus, the fuel pump 141 and the fuel line 142 together constitute a fuel delivery system.

The turbojet engine 160 shown is the preferred power plant, however, other types of power plants may be substituted for the turbojet engine 160, such as a micro gas turbine, and remain within the scope of this invention.

Also included in the smoker box 110 is a mist oil tank 150, the mist oil tank 150 providing mist oil to an eductor 170 also housed in the smoker box 110. The mist oil is supplied to the ejector 170 through a mist oil pipeline 152 connected between the mist oil tank 150 and the ejector 170, and specifically, the mist oil enters the ejector 170 from a mist oil inlet 172 provided on the ejector 170 through the mist oil pipeline 152. Preferably, a mist oil pump 151 is installed in the mist line 152 to assist in supplying the mist in the mist tank 150 to the ejector 170. Thus, the mist pump 151 and the mist line 152 together constitute a mist oil delivery system.

Optionally, a mixer 174 including an agent inlet 173 is further disposed on the injection device 170, and the agent inlet 173 is connected to an agent delivery device 200, which will be described below, and receives the agent from the agent delivery device 200. The mixer 174 is disposed around the injector 170 outside the injector 170, and a plurality of circumferential holes 175 are disposed between the mixer 174 and the injector 170 around the circumference of the injector 170, the circumferential holes 175 communicating the interior of the injector 170 with the mixer 174.

Preferably, the injection means 170 is designed with a smaller diameter, in the form of a constriction, at a position corresponding to the mixer 174, in particular at the portion thereof provided with the circumferential hole 175. Thus, the flow velocity of hot air flow passing through the necking part is increased, so that the hot air flow can be more fully mixed with the material agent and the like, and the mixing degree of the material agent is improved. Moreover, the accelerated flow rate can also impact the material, reducing or avoiding material blockage in the eductor 170. Similarly, the portion of the injection device 170 where the mist inlet 172 is disposed may be designed in a necking shape to enhance the atomization effect of the mist.

Fig. 2 shows a top view of a dose delivery device 200 optionally included in the smoke generating device, and fig. 3 shows a side view of the dose delivery device 200. The agent conveying device 200 includes a screw 210 and a conveyor belt 230. The two ends of the conveyor belt 230 are respectively provided with a conveyor belt driving shaft 231 and a conveyor belt driven shaft 232, and the conveyor belt driving shaft 231 drives the conveyor belt 230 to operate so as to convey the material agent from one end of the conveyor belt driven shaft 232 to one end of the conveyor belt driving shaft 231.

The screw 210 is provided at one end of the belt driving shaft 231 of the belt 230, and extends substantially in parallel with the belt driving shaft 231. The material transported on the conveyor belt 230 is fed onto the screw 210, and then, as the screw 210 rotates, the material is fed in the direction indicated by the arrow Y to the discharge opening 211, and the discharge opening 211 is communicated with the material inlet 173 of the injection unit 170 of the smoke generator unit 100, so that the material is supplied to the injection unit 170, for example, the discharge opening 211 and the material inlet 173 are connected together by a pipeline.

The agent delivery device 200 further comprises a driving mechanism 220, and the driving mechanism 220 can be used for driving the screw 210 and the conveyor belt 230 to operate so as to deliver the agent. One exemplary configuration of the drive mechanism 220 can be seen in fig. 3, the drive mechanism 220 having a motor gear 221, the motor gear 221 being coupled to an output shaft of a drive motor (not shown). Further, a screw gear 222 is provided at one end of the screw 210, and a driving shaft gear 223 is provided at one end of the belt driving shaft 231. The motor gear 221 is engaged with at least one of the screw gear 222 and the axle shaft gear 223.

For example, the motor gear 221 may be engaged with both the screw gear 222 and the driving shaft gear 223, such that the screw gear 222 and the driving shaft gear 223 may be driven by the motor gear 221 to rotate the screw 210 and the belt driving shaft 231, and the belt driving shaft 231 rotates to drive the belt 230 to run.

Alternatively, the motor gear 221 may be engaged with one of the screw gear 222 and the driving shaft gear 223, and the screw gear 222 and the driving shaft gear 223 are engaged with each other. Thus, motor gear 221 can drive one of screw gear 222 and drive shaft gear 223 to rotate and in turn indirectly drive the other of screw gear 222 and drive shaft gear 223 to rotate. In this way, the screw 210 and the belt driving shaft 231 are also driven to rotate, and the belt 230 is driven to run via the belt driving shaft 231.

The driving mechanism 220 composed of the motor gear 221, the screw gear 222 and the driving shaft gear 223 can realize synchronous operation of the screw 210 and the conveyor belt 230, and realize the conveyance of the feed from the conveyor belt 230 to the screw 210 and then to the injection device 170.

The drive mechanism 220 may take other forms besides the disclosed gear train transmission structure, such as a sprocket drive mechanism, a pulley drive mechanism, and the like.

Preferably, as another embodiment of the dosage delivery device 200 shown in fig. 4, a plurality of baffles 233 may be disposed on the conveyor belt 230. The baffles 233 can improve the delivery capacity of the conveyor 230, thereby increasing the amount of the agent delivered.

The operation of the smoke screen generation system of the present invention will now be described in detail.

Fig. 5 shows a smoke screen generation system comprising a smoke generator device 100 and a charge delivery device 200. In the preferred construction shown in the drawings, the smoking device 100 and the charge delivery device 200 are arranged in a vertical orientation with the charge delivery device 200 being located above the smoking device 100.

During operation of the smoke screen generation system, an operator operates the button 121 on the control panel 120 to activate the fuel pump 141, such as by activating the fuel pump 141 via the power and control module 130. Fuel from the fuel tank 140 is thus delivered to the turbojet engine 160 by the fuel pump 141 via the fuel line 142. The turbojet engine 160 is fueled by fuel to produce a hot gas stream having a velocity. The hot gas stream is delivered to the eductor inlet 171 of the eductor 170 and travels towards the portion where the mist inlet 172 and/or the dose inlet 173 are located.

The fog oil pump 151 can be started by the operator through the operation of the corresponding button 121 on the control panel 120, and under the action of the fog oil pump 151, the fog oil in the fog oil tank 150 is conveyed to the fog oil inlet 172 on the ejector 170 through the fog oil pipeline 152. The incoming mist from the mist inlet 172 mixes with the hot gas stream from the turbojet engine 160, is sufficiently atomized, and is discharged from the eductor outlet 176. The atomized fog oil forms a smoke screen capable of effectively shielding visible light.

Alternatively, the mist oil in the mist oil tank 150 may be replaced with other types of reagents such as insecticide and disinfectant, and the corresponding injection device 170 may be adjusted to a corresponding type. In this manner, the smoke generator device 100 may be used for decontamination, pest control, and the like.

Further, the feeding device 200 can be started, that is, the motor is turned on to drive the motor gear 221 connected to the motor to rotate, and the motor gear 221 further drives the screw gear 222 and the driving shaft gear 223 to rotate. The screw 210 and the conveyor belt 230 are thereby driven to move, the feed is conveyed by the conveyor belt 230 onto the screw 210 and is supplied via the screw 210 from the feed inlet 173 to the mixer 174 of the eductor 170, after being sufficiently dispersed in the mixer 174, the feed is supplied to the eductor 170 via the plurality of peripheral ring holes 175 between the mixer 174 and the eductor 170. The charge is then mixed with the hot gas stream from the turbojet engine 160 to form a uniform smoke curtain.

The agent may be a substance having infrared interference properties such that the resulting smoke screen forms an effective infrared interference smoke screen.

Alternatively, the smoke screen generation system may operate only by operating the material delivery device 200 to deliver material, such as material having infrared interference characteristics, to the eductor device 170 to generate an infrared interference smoke screen. At this time, the mist oil is not supplied to the ejector air inlet 171 of the ejector 170, and thus no visible light shielding smoke is generated. It can be seen that the construction of the smoke screen generation system of the present invention allows for the delivery of both smoke screens in combination, and optionally the delivery of only a single smoke screen.
