A smoke generating device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1, a smoke generating device according to an embodiment of the present invention includes a heater 1, an oil inlet channel 2, an accumulator 3, a swash plate pump 4, and a first valve 5.

The heater 1 is provided with a heating channel, when the smoke oil flows through the heating channel, the heater 1 works and transfers heat to the smoke oil, the temperature of the smoke oil is increased, the smoke oil is converted into smoke, and finally the smoke oil is discharged from an outlet of the heating channel. The heater 1 can increase the temperature of the heating channel in an electromagnetic induction heating mode, and then the heating channel transfers heat to the smoke oil in a heat transfer mode; the heat may also be transferred to the heating channel by heat transfer to increase the temperature of the heating channel, or by radiation heating to increase the temperature of the heating channel. In the present embodiment, the specific heating method of the heater 1 is not limited.

The oil inlet channel 2 can be communicated with a smoke oil supply source 6 and inlets of the heating channels, the smoke oil supply source 6 can be a container containing smoke oil, when the swash plate pump 4 arranged on the oil inlet channel 2 works, the smoke oil can be driven to be transferred to the inlets of the heating channels from the smoke oil supply source 6 through the oil inlet channel 2, the smoke oil is heated and converted into smoke after entering the heating channels, and then the smoke oil is sprayed from outlets of the heating channels to form smoke columns.

When the swash plate pump 4 works, smoke oil can be driven to be transferred into a pressurizing cavity of the energy accumulator 3 communicated with the oil inlet channel 2 through the smoke oil supply source 6 through the oil inlet channel 2. The check valve 7 arranged on the oil inlet passage 2 between the swash plate pump 4 and the pressurizing chamber can prevent the smoke oil in the pressurizing chamber from flowing back into the swash plate pump 4.

In the preparation stage of the smoke generating device for spraying smoke, the swash plate pump 4 conveys smoke oil into the pressurizing chamber of the energy accumulator 3 so as to increase the pressure of liquid in the oil inlet channel 2, specifically, the pressure of liquid in the oil inlet channel 2 between the one-way valve 7 and the pressurizing chamber to a preset value. In one embodiment, the smoke generating device further comprises a pressure sensor 8, wherein the pressure sensor 8 is capable of collecting information on the pressure of liquid in the oil inlet channel 2 between the one-way valve 7 and the pressurizing chamber in the oil inlet channel 2.

When the smoke column needs to be sprayed, the first valve 5 arranged on the oil inlet channel 2 in front of the inlet of the heating channel is opened, the energy accumulator 3 releases pressure, smoke oil in the pressurizing cavity and smoke oil in the oil inlet channel 2 between the one-way valve 7 and the first valve 5 are enabled to be rapidly transferred to the heating channel, and therefore the smoke column is rapidly formed. In the process of continuously spraying the smoke column, the energy accumulator 3 can also relieve flow fluctuation in the oil inlet channel 2 in the working process of the swash plate pump 4, so that the spraying height of the smoke column can be kept in a set range. If the spray of the smoke column needs to be suspended, the first valve 5 is closed, the smoke oil is stopped from entering the heating channel, and meanwhile, the swash plate pump 4 can continue to work until the pressure of the liquid in the oil inlet channel 2 between the one-way valve 7 and the pressurizing chamber reaches a preset value.

Under the conditions that the smoke oil in the smoke oil supply source 6 is exhausted and then is added again, or the smoke oil in the oil inlet channel 2 at the front end of the swash plate pump 4 contains bubbles and the swash plate pump 4 is drier, the working pressure of the energy accumulator 3 can cause the swash plate pump 4 to difficultly suck the smoke oil in the smoke oil supply source 6 and complete pressurization, and continuous idle rotation can damage the smoke oil supply source 6. Thus, in this embodiment, the smoke generating device further comprises a first oil return channel 9, the first oil return channel 9 communicating the pressurizing chamber and the output end of the swash plate pump 4; and a second valve 10, said second valve 10 being arranged on the first oil return channel 9. When the smoke oil in the smoke oil supply source 6 is exhausted and then the smoke oil is added again, or when the smoke oil in the oil inlet channel 2 at the front end of the swash plate pump 4 contains bubbles and the swash plate pump 4 is drier, the first valve 5 is closed, the second valve 10 is opened, the smoke oil contained in the pressurization cavity is discharged through the first oil return channel 9, the energy accumulator 3 is depressurized, the swash plate pump 4 is started at the moment, the swash plate pump 4 can easily extract the smoke oil in the smoke oil supply source 6 and drive the smoke oil to be discharged through the oil inlet channel 2 and the first oil return channel 9, and the second valve 10 can be closed after the smoke oil is fully filled in the swash plate pump 4 and the pipeline so as to stop the smoke oil from being discharged through the first oil return channel 9; the swash plate pump 4 continues to work, transfers the fog oil to the energy accumulator 3 for pressurization until the pressure of the liquid in the oil inlet channel 2 between the check valve 7 and the pressurization chamber reaches a preset value, and the preparation action is completed. Therefore, the problem that the swash plate pump 4 is difficult to suck the smoke oil in the smoke oil supply source 6 and complete the pressurization action due to the remaining working pressure of the energy accumulator 3 is solved, and meanwhile, the swash plate pump 4 is prevented from being damaged due to continuous idling.

In one embodiment, the smoke generating device further comprises a second oil return channel 11, said second oil return channel 11 being in communication with the inlet of the heating channel; a third valve 12, said third valve 12 being arranged on the second oil return channel 11. When the smoke generating device stops spraying smoke, if the device is shut down, the third valve 12 is opened, smoke oil in the heating channel can be discharged through the second oil return channel 11, and the smoke oil is prevented from being crystallized and blocking the heating channel. After the smoke oil is exhausted, the third valve 12 is closed.

In one embodiment, the heater 1 has at least two heating channels, each heating channel has an inlet in communication with the oil inlet channel 2 and an outlet in communication with a single nozzle 13 of the heater 1. The oil inlet channel 2 comprises oil inlet branch channels 14 with the same quantity as the heating channels, and each oil inlet branch channel 14 is respectively communicated with the corresponding heating channel. The smoke generating device further comprises fourth valves 15, the number of the fourth valves is the same as that of the heating channels, and each fourth valve 15 is arranged on an oil inlet sub-channel in front of an inlet of the corresponding heating channel and used for opening and stopping smoke oil from entering the heating channel.

By adopting a plurality of heating channels, the spraying amount of the smoke can be flexibly adjusted, and the quantity of the opened fourth valve 15 is in positive correlation with the spraying amount of the smoke under the condition that the output flow of the swash plate pump 4 meets the requirement. For example, only one fourth valve 15 is opened, and the aerosol oil is heated and atomized only through the corresponding one heating channel; if two fourth valves 15 are opened, the smoke oil can be heated and atomized through corresponding two heating channels at the same time, and the output flow of the swash plate pump 4 is large, so that the smoke oil can be conveyed to a plurality of heating channels at the same time, and the spray amount of smoke can be remarkably increased when the two fourth valves 15 are opened (relative to the condition that one fourth valve 15 is opened), so that the smoke column is larger. The first valve 5 is closed, so that the smoke can be immediately sprayed, and the operation is simple.

Preferably, the first valve 5, the second valve 10, the third valve 12 and the fourth valve 15 are all solenoid valves.
