[0026] Please see Figures 1 to 5 This embodiment provides an air column smoke machine 1, which is a device used to create stage effects. The air column smoke machine 1 includes components such as a housing 10, an oil tank 30, a nozzle 20, a smoke generator 2, a pipe assembly, a connector 5, a solenoid valve 32, and an oil pump 31. The housing 10 is a three-dimensional rectangular shape and is used to house the oil tank 30, the smoke generator 2, the connector 5, the pipe assembly, the solenoid valve 32, and the oil pump 31.

[0027] The oil tank 30 stores liquid oil for supplying to the smoke generator 2. The oil tank 30 is provided with an oil inlet 301, through which liquid oil can be poured into the oil tank 30 and also extracted from the oil tank 30 through the oil inlet 301. An oil tank handle 302 is provided on the side of the oil tank 30, which the user can grasp to place the oil tank 30 into and remove it from the housing 10.

[0028] The smoke generator 2 includes an air outlet column 21 located at its top, which is detachably connected to the nozzle 20. In this embodiment, a threaded connection is preferred, which allows for a stable connection and facilitates connection and disassembly. In other embodiments, the air outlet column 21 and the nozzle 20 may be snap-fitted or fixed with screws.

[0029] The smoke generator 2 receives liquid oil from the oil tank 30. A heater is installed inside the smoke generator 2 to raise the internal temperature, thereby heating the liquid oil received inside and atomizing it. The smoke forms a column and is ejected through the exhaust column 21 and nozzle 20 to create a unique stage effect.

[0030] Connector 5 is a three-way connector 5. In this embodiment, it is preferably a T-type three-way connector 5. Connector 5 includes a first connection port 51, a second connection port 52 and a third connection port 53 that are interconnected. The first connection port 51 is connected to the oil pump 31 and the second connection port 52 is connected to the solenoid valve 32.

[0031] The pipeline assembly is connected to the oil tank 30, oil pump 31, connector 5 and smoke generator 2, and liquid oil flows within the pipeline assembly.

[0032] Specifically, the piping assembly includes a first pipe 41, a second pipe 42, and a third pipe 43. One end of the first pipe 41 is connected to the oil inlet 301, and the other end of the first pipe 41 is connected to the oil pump 31. One end of the second pipe 42 is connected to the oil inlet 301, and the other end of the second pipe 42 is connected to the solenoid valve 32. One end of the third pipe 43 is connected to the third connection port 53, and the other end of the third pipe 43 is connected to the smoke generator 2.

[0033] Furthermore, the oil pump 31 includes a first oil pump port and a second oil pump port, the first oil pump port being connected to the first pipeline 41, and the second oil pump port being connected to the first connection port 51. The solenoid valve 32 includes a first valve port and a second valve port, the first valve port being connected to the second pipeline 42, and the second valve port being connected to the second connection port 52.

[0034] Preferably, the smoke generator 2 is provided with an oil receiving pipe 22, and the other end of the third pipe 43 is connected to the oil receiving pipe 22.

[0035] The oil pump 31 is used to control the flow of liquid oil from the oil tank 30 to the smoke generator 2. The oil pump 31 provides power to draw liquid oil from the oil tank 30 and cause the liquid oil to flow to the smoke generator 2.

[0036] The solenoid valve 32 is used to control the flow of liquid oil from the smoke generator 2 to the oil tank 30. The flow path of the liquid oil is controlled by setting the solenoid valve 32 to the open or closed state.

[0037] Specifically, when the smoke generator 2 needs to atomize the liquid oil to form a column of gas and spray it out through the nozzle 20, the oil pump 31 is turned on and the solenoid valve 32 is turned off. At this time, the liquid oil is drawn out from the oil tank 30 under the power provided by the oil pump 31 and enters the smoke generator 2 through the first pipe 41, the oil pump 31, the first connection port 51, the third connection port 53 and the third pipe 43. The smoke generator 2 is started and generates a column of gas.

[0038] When the smoke generator 2 needs to stop producing air column, the oil pump 31 is turned off, the solenoid valve 32 is opened, the oil tank 30 stops supplying liquid oil to the smoke generator 2, and because the heater generates high temperature inside the smoke generator 2, the air pressure inside the smoke generator 2 increases. Guided by the solenoid valve 32, the liquid oil remaining in the smoke generator 2 flows into the oil tank 30 through the third pipe 43, the third connection port 53, the solenoid valve 32, the second connection port, and the second pipe 42, thereby stopping the air column.

[0039] In this embodiment, the single solenoid valve 32 structure enables the liquid oil to flow out of the smoke generator 2 quickly, thereby achieving the purpose of quickly stopping the air column.

[0040] It is understood that in this embodiment, the pipeline assembly, connector 5, solenoid valve 32 and oil pump 31 are provided in two sets so that the liquid oil can be supplied from the oil tank 30 to the smoke generator 2 and returned from the smoke generator 2 to the oil tank 30 more quickly. In some embodiments, one or more sets are provided.

[0041] Furthermore, a thermostat is installed inside the smoke generator 2. The thermostat is used to monitor the temperature inside the smoke generator 2. When the temperature of the smoke generator 2 reaches a certain limit, the thermostat takes measures to stop heating the generator to prevent the smoke generator 2 from being damaged due to excessive temperature.

[0042] Furthermore, a cooling fan 33 is provided on the outside of the smoke generator 2. The cooling fan 33 is used to reduce the temperature inside the chassis 10 to prevent the temperature inside the chassis 10 from becoming too high.

[0043] The air column smoke machine 1 also includes a light panel 24. Multiple light panels 24 are arranged around the nozzle 20. When the nozzle 20 sprays out an air column 21, the light panel 24 emits light to create a unique stage effect in conjunction with the air column.

[0044] Furthermore, a cylindrical protective cover 23 is provided around the outside of the nozzle 20 to prevent damage to the nozzle 20.

[0045] In order for the exhaust column 21 to extend outside the housing 10 and connect with the nozzle 20, the upper end face 101 of the housing 10 is provided with an opening 1011. The exhaust column 21 extends outside the housing 10 through the opening 1011, thus creating a gap between the exhaust column 21 and the housing 10. In order to prevent liquid from entering the interior of the housing 10 through this gap and causing damage to the smoke generator 1, a sealing module is detachably provided between the exhaust column 21 and the housing 10. The sealing module is used to seal the gap between the exhaust column 21 and the housing 10 to ensure that the smoke generator 2 maintains good waterproof function.

[0046] The sealing module is located between the lower end of the nozzle 20 and the upper end face 101 of the housing 10. The nozzle 20 fixes the sealing module to prevent it from loosening or falling off.

[0047] The sealing module includes a pressure plate 61, a heat insulation plate 62, and a sealing plate 63. The pressure plate 61 is located on the top layer, the sealing plate 63 is located on the bottom layer, and the heat insulation plate 62 is located between the pressure plate 61 and the sealing plate 63. The pressure plate 61 is pressed and fixed by the nozzle 20. The sealing plate 63 contacts the upper end face 101 of the casing 10 to seal the gap between the air column 21 and the upper end face 101 of the casing 10. When the air column range hood 1 is in a high-temperature environment for a long time, the heat insulation plate 62 can prevent the external high temperature from corroding the sealing plate 63, thereby extending the life of the sealing plate 63.

[0048] Furthermore, the sealing module is connected to the air outlet column 21 via a sleeve-fitting method. The pressure plate 61, heat insulation plate 62, and sealing plate 63 have circular holes at their centers. The air outlet column 21 is cylindrical. This structure allows for a seamless connection between the pressure plate 61, heat insulation plate 62, and sealing plate 63 and the air outlet column 21. When the sealing module is damaged due to long-term use, simply align the nozzle 20 with the air outlet column 21 and unscrew it. Remove the old sealing module, install the new sealing module, and finally screw the nozzle 20 back on.

[0049] Instead of the common method of sealing the gap between the air column 21 and the casing 10 with glue, the removable sealing module can be replaced more easily, ensuring the long-term stable use of the air column range hood 1.

[0050] The housing 10 is detachably provided with movable handles 102 on both sides along its length. The movable handles 102 allow the user to easily lift the air column range hood 1. In some embodiments, casters may be provided at the bottom of the housing 10 to facilitate the movement of the air column range hood 1.

[0051] The chassis 10 has a control panel 71 on its side in the width direction. The control panel 71 is electrically connected to the various integrated modules installed inside the chassis 10. Users can view information such as the usage time of the air column smoke machine 1, the temperature of the smoke generator 2, and the remaining oil level in the oil tank 30 through the control panel 71 so as to intervene in a timely manner. At the same time, the control panel 71 can control the running time of the smoke generator 2, the number of air column ejections and the interval time, the opening and closing of the solenoid valve 32, and the opening and closing of the oil pump 31.

[0052] Below the control panel 71 are a power interface 72 and a start switch 73. The power interface 72 is used to receive external power and supply power to the components on the air column range hood 1. The start switch 73 determines whether the air column range hood 1 is in a usable state when it is turned on or off.

[0053] Furthermore, ventilation holes are provided on the bottom and sides of the chassis 10, which allow air to circulate between the inside and outside of the chassis 10, thereby reducing the temperature inside the chassis 10.

[0054] Furthermore, the bottom surface of the chassis 10 is detachably provided with a base 103, which is used to support the chassis 10, and multiple bases 103 are provided.

[0055] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
