[0054] Based on the above technical solution, it further includes a multi-way solenoid valve 6. The multi-way solenoid valve 6 and a gas cylinder 38 are fixedly installed inside the equipment box 3. The gas cylinder 38 is communicated with the multi-way solenoid valve 6 through a pipeline, and the multi-way solenoid valve 6 is communicated with the gas joint 41 through a pipeline;

[0055] It further includes a battery 39, a controller 33, and a remote control switch 37. The battery 39 is electrically connected to the multi-way solenoid valve 6, the pulse igniter 7, the controller 33, and the remote control switch 37 respectively. The remote control switch 37 is electrically connected to the controller 33. The controller 33 is used to control the ignition of the pulse igniter 7 and the on / off of the multi-way solenoid valve 6.

[0056] Working principle:

[0057] Place the smoke cake 29 according to Figure 6They are arranged in the drawer 2 in such a way that preferably two layers of smoke cakes 29 are used at each position for placing the smoke cakes 29. By changing the number of layers of the smoke cakes 29, the burning time of the smoke cakes and the smoke emission concentration are determined.

[0058] After the drawer 2 is pushed into the smoke emission box 1, the two fixing bars 12 on the front side of the smoke emission box 1 are pulled up and locked with the buckles 13 to ensure that the drawer 2 will not slide off during the movement of the device.

[0059] During use, the valve of the gas cylinder 38 itself is opened. Preferably, the equipment box 3 can be provided with an opening (not shown in the figure) to facilitate reaching into the equipment box 3 to open or close the valve of the gas cylinder 38 itself. The switch 34 is pressed to power on the equipment in the equipment box 3.

[0060] Remotely, the remote control switch 37 is remotely controlled to close, the second relay 36 is powered on to send a signal (high level) to the controller 33, and the controller 33 controls the multi-way solenoid valve 6 to be connected to the gas connectors 41 in each drawer 2 in turn, and the controller 33 controls the pulse igniter 7 to ignite the ignition needles 45 in each drawer 2 in turn.

[0061] For example, the multi-way solenoid valve 6 first connects the gas connector 41 in the uppermost drawer 2 to the gas cylinder 38, and the combustible gas in the gas cylinder 38 enters the gas connector 41 in the uppermost drawer 2 through the solenoid valve 6. At this time, the gas connectors 41 in the other drawers 2 are not connected to the gas cylinder 38.

[0062] After the combustible gas passes through the gas through-hole 43, its diameter decreases, so the flow rate increases. After a period of time, when the combustible gas in the flame jet tube 42 reaches a certain concentration, the pulse igniter 7 energizes the ignition needle 45, and an electric spark is generated between the ignition needle 45 and the flame jet tube 42, and the electric spark ignites the combustible gas in the flame jet tube 42. The flame passes through the front end of the flame jet tube 42 and then passes through the fourth through-hole 261 to ignite the smoke cake 29 closest to the fourth through-hole 261. Among them, the fast forward flow rate of the combustible gas can prevent the flame from entering the gas through-hole 43. Among them, air enters the flame jet tube 42 through the fifth through-hole 44 to provide oxygen. Among them, the second partition plate 26 forms a combustion space with the side plate 23, the bottom plate 24 and the first partition plate 25 respectively, and the combustion space is only connected to the placement space 28 through the fourth through-hole 261, so as to prevent the flame from overflowing the space and igniting the smoke cakes 29 in other placement spaces 28.

[0063] After that, the multi-way solenoid valve 6 and the pulse igniter 7 are closed. At this time, the smoke cake 29 closest to the fourth through-hole 261 is burning, and the burning smoke cake 29 will ignite the adjacent smoke cake 29. The smoke cakes 29 are ignited one by one along an S-shaped route, and the ignition sequence is as Figure 6 shown by the arrows in

[0064] During the combustion of the smoke cake 9, the smoke passes through the first through-hole 15, the second through-hole 211, and overflows outside the smoke generating box 1 from above the side plate 23, meeting the required smoke generating demand.

[0065] After a certain period of time (when the smoke cake 29 in the topmost ignited layer is basically burned out), the second highest drawer 2 starts to be ignited, with the same principle as the topmost drawer 2. In this way, all the smoke cakes 29 in the drawers 2 are sequentially ignited one by one from top to bottom (the order can be variable), extending the smoke generating duration and also keeping the smoke generating amount consistent.

[0066] When some of the drawers 2 are not ignited, the remote control switch 37 can be controlled to disconnect through the remote control, thus stopping the subsequent ignition.

[0067] After use, rotate to close the valve of the gas tank 38, turn off the switch 34, open the buckle 13 and turn down the fixing strip 12, then pull out the drawer 2 and pour out the burned smoke cake 29 from the drawer 2.

[0068] Under good sunlight conditions, the photovoltaic panel 31 can be rotated and opened for the battery 39 to be charged, with sunlight directly shining on the surface of the photovoltaic panel 31 approximately.

Among them, the guide rail 11 is a horizontal partition that divides the smoke generating box 1 into multiple layers.

[0088] Arrange the smoke cakes 29 in the drawers 2 in the Figure 6 way. It is preferred to use two layers of smoke cakes 29 at each position for placing the smoke cakes 29. By changing the number of layers of the smoke cakes 29, the burning time of the smoke cakes and the smoke emission concentration are determined.

[0089] After the drawer 2 is pushed into the smoke generating box 1, pull up the two fixing strips 12 on the front side of the smoke generating box 1 and lock them with the buckle 13 to ensure that the drawer 2 will not slide off during the movement of the device.

[0090] When in use, open the valve of the gas tank 38 itself. Preferably, the equipment box 3 can be provided with an opening (not shown in the figure) to facilitate reaching into the equipment box 3 to open or close the valve of the gas tank 38 itself. Press the switch 34 to power on the equipment in the equipment box 3.

[0091] Remotely use the remote control to remotely control the remote control switch 37 to close. The second relay 36 is powered on and sends a signal (high level) to the controller 33. Then, the push rod of the electric push rod 87 moves downward. By pulling the steel cable 92, the second sealing plate 9 is pulled upward until the sixth through hole 90 coincides with the first through hole 15 on the left side. Then, the electric push rod 87 stops moving and maintains its position. Among them, the second sealing plate 9 moves upward along the guide rail 91, and the guide rail 91 keeps it attached to the smoke generating box 1. Then, the first sealing plate 84 corresponding to the layer where the smoke cake 29 needs to burn is driven by the motor to rotate downward and stops blocking and sealing the first through hole 15 on the right side. Then, the controller 33 controls the multi-way solenoid valve 6 to be connected to the gas joint 41 in the drawer 2, and the controller 33 controls the pulse igniter 7 to ignite the ignition needle 45 in the drawer 2.

[0092] For example, the multi-way solenoid valve 6 first connects the gas connector 41 in the uppermost drawer 2 to the gas tank 38. The combustible gas in the gas tank 38 enters the gas connector 41 in the uppermost drawer 2 through the solenoid valve 6. At this time, the gas connectors 41 in the drawers 2 of other layers are not connected to the gas tank 38.

[0093] After the combustible gas passes through the gas through-hole 43, its diameter decreases, so the flow rate increases. After a period of time, when the combustible gas in the flame jet tube 42 reaches a certain concentration, the pulse igniter 7 energizes the ignition needle 45, and an electric spark is generated between the ignition needle 45 and the flame jet tube 42. The electric spark ignites the combustible gas in the flame jet tube 42. The flame passes through the front end of the flame jet tube 42 and then passes through the fourth through-hole 261 to ignite the smoke cake 29 closest to the fourth through-hole 261. Among them, the fast forward flow rate of the combustible gas can prevent the flame from entering the gas through-hole 43. Among them, air enters the flame jet tube 42 through the fifth through-hole 44 to provide oxygen. Among them, the second partition 26 forms a combustion space with the side plate 23, the bottom plate 24, and the first partition 25 respectively. The combustion space is only connected to the placement space 28 through the fourth through-hole 261, so as to prevent the flame from overflowing the space and igniting the smoke cakes 29 in other placement spaces 28.

[0094] After that, the multi-way solenoid valve 6 and the pulse igniter 7 are closed. At this time, the smoke cake 29 closest to the fourth through-hole 261 is burning, and the burning smoke cake 29 will ignite the adjacent smoke cake 29. The smoke cakes 29 are ignited one by one along an S-shaped route, and the ignition sequence is as Figure 6 shown by the arrow in.

[0095] When the smoke cake 29 is burning, the solenoid valve 57 is opened, and the compressed air in the compressed air source 86 enters the compressed gas inlet 56 through the pipeline and the solenoid valve 57 in sequence. Then the compressed air is ejected from the nozzle 51 at a high speed, forming a low pressure in the suction chamber 53. The flue gas generated by the burning of the smoke cake 29 is inhaled into the suction chamber 53 from the flue gas inlet 52 after passing through the smoke generating box 1, the first through-hole 15 on the right side, and the smoke collecting box 8 in sequence. The flue gas and the compressed air are mixed in the mixing chamber 54 and finally ejected from the diffuser chamber 55. The movement direction of the flue gas is as Figure 11 shown by the arrow in. Among them, the compressed air source 86 is a high-pressure gas cylinder or an air compressor.

[0096] The injection speed and height of the flue gas are increased by the injection pump 5, and a certain negative pressure is generated in the corresponding layer of the smoke generating box 1, so that the outside air is sucked into the corresponding layer from the first through hole 15 on the left for the continued burning of the tobacco cake 29. It should be noted that since the torch head 4 is located on the left and the injection pump 5 is located on the right, under the airflow from left to right, it is convenient for the tobacco cake 29 on the left side of the channel 20 to ignite the tobacco cake 29 on the right side of its channel 20. Because in the preferred solution, the distance between the adjacent first partition plates 25 on the left and right sides is the diameter of the tobacco cake 29, thus avoiding the left and right displacement of the tobacco cake 29. This results in a gap between the tobacco cakes 29 on both sides of the channel 20, and the airflow facilitates the movement of the sparks over a greater distance to ignite the tobacco cake 29 on the right side of the channel 20.

[0097] After a certain period of time (when the tobacco cake 29 in the layer where ignition occurred last is basically burned out), the second highest drawer 2 starts to be ignited, and the principle is the same as that of the topmost drawer 2. In this way, all the tobacco cakes 29 in all the drawers 2 are sequentially ignited one by one from top to bottom (the order can be variable), extending the duration of smoke generation and also keeping the smoke generation amount consistent. It should be noted that the first sealing plate 84 corresponding to the layer where combustion is completed will be driven by the motor 85 to rotate upward and reset, thus blocking the first through hole 15 on the right side to prevent air from directly entering the smoke collecting box 8 from the first through hole 15 on the right side to dilute the flue gas.

[0098] When it is necessary to stop the combustion during the burning process of the tobacco cake 29 in a layer, the push rod of the electric push rod 87 resets upward, and the second sealing plate 9 resets downward under its own weight to block the first through hole 15 on the left side. The injection pump 5 extracts the air in this layer, and the air and oxygen content in this layer decrease, and the burning tobacco cake 29 is extinguished, thus aborting the smoke generation in this layer.

[0099] After use, rotate to close the valve of the gas tank 38, turn off the switch 34, and the second sealing plate 9 and the first sealing plate 84 are respectively driven to move to their initial positions. The compressed air source 86 stops supplying gas to the injection pump 5, and other electrical equipment stops working. Finally, open the buckle 13 and turn the fixing strip 12 downward, then pull out the drawer 2 and pour out the burned tobacco cake 29 from the drawer 2.

[0100] Under good sunlight conditions, the photovoltaic panel 31 can be rotated and opened, and the battery 39 is charged, with sunlight directly irradiating the surface of the photovoltaic panel 31. Among them, the battery 39 supplies power to all the electrical equipment.

[0101] When the battery 39 has a low power or no power:

[0102] At this time, the air compressor serving as the compressed air source 86 cannot work, and the normally closed solenoid valve 57 blocks the compressed gas inlet 56. At this time, if there is still a small amount of power, normal electric ignition can be carried out. If there is no power, the initial tobacco cake 29 can be manually ignited.

[0103] At this time, the upward jet pump 5 is equivalent to a chimney. When the smoke cake 29 burns, the negative pressure generated in the layer by the chimney effect causes the flue gas and air to move, which can also increase the speed and height of the flue gas, but it is not as good as using compressed gas.

[0104] The present invention has been described by way of example above, but the present invention is not limited to the above specific embodiments. Any modification or variation based on the present invention falls within the scope of protection required by the present invention.
