However, there are many factors affecting precision control in mechanical pumps, such as: machining precision and tightness of mechanical pumps, driving speed and valve control ratio, comprehensive working efficiency, etc. Among them, the mechanical structure in the mechanical pump feeding system is complex, with a large number of movable parts, sealing areas, and electrical control nodes, which are prone to cause equipment failures. Moreover, in the actual proportional control process, the attenuation of the driving motor speed, valve opening, and mechanical moving parts' loss and efficiency in the mechanical pump control response becomes more and more serious as the running time increases.

[0060] The working process and principle of the air pump type tobacco flavoring device provided by the present invention:

[0061] At the start of batch production, the controller simultaneously opens the first liquid injection solenoid valve 33 and the second liquid injection solenoid valve 34. Under the action of gravity, the flavor liquid in the formula stock solution tank 31 is injected into the first air pump tank 1 and the second air pump tank 2 from the bottom of the formula stock solution tank 31 through the tee liquid injection pipe 32. When the first ultrasonic liquid level sensor 13 detects that the liquid level in the first air pump tank 1 has risen to a position 60 mm away from the top cover of the first air pump tank 1, it transmits the detection signal to the controller, and the controller closes the first liquid injection solenoid valve 33, and the first air pump tank 1 completes the feeding process. Similarly, when the second ultrasonic liquid level sensor 23 detects that the liquid level in the second air pump tank 2 has risen to a position 60 mm away from the top cover of the second air pump tank 2, it transmits the detection signal to the controller, and the controller closes the second liquid injection solenoid valve 34, and the second air pump tank 2 completes the feeding process. The pre-filling processes of the first air pump tank 1 and the second air pump tank 2 are carried out simultaneously. There is a space with a height of 60 mm between the highest liquid level and the top cover as a constant pressure chamber for gas, so as to avoid a large number of bubbles being generated when the high-pressure gas pipe contacts the liquid and enters the liquid flow detector pipeline, resulting in abnormal flow detection and empty pipe state.

[0062] After the controller receives the detection signals from the first ultrasonic liquid level sensor 13 and the second ultrasonic liquid level sensor 23, it closes the first liquid injection solenoid valve 33 and the second liquid injection solenoid valve 34. Then, the controller opens the first solenoid valve 42 and the first one-way valve 14, and at the same time opens the opening of the liquid flow regulating valve 7 to 40%. The high-pressure gas in the high-pressure gas source device is decompressed by the main air source pressure reducing valve 45 and is input into the first air pump tank 1 through the first gas pipeline 41 to apply pressure to the liquid in the first air pump tank 1 and push the liquid into the tee pressure-bearing hose 9. When the fluid flow detector 5 connected to the tee pressure-bearing hose 9 detects that the empty pipe signal disappears and detects the actual liquid flow signal, it transmits the detection signal to the liquid flow digital processor 6 for processing, and the processed data is transmitted to the controller. At this time, the controller immediately closes the liquid flow regulating valve 7, and thus the pre-filling process is completed.

[0063] The controller calculates the flavor liquid feeding flow ratio used in the current batch production based on the total weight of the batch materials, the total weight of the flavor liquid, and the set flow of the electronic scale. According to the real-time incoming material flow of the electronic scale, the real-time liquid flow ratio signal is finally calculated by comparing with the flavor liquid feeding ratio. The digital processor of the liquid flow regulating valve 7 simultaneously receives the liquid flow ratio signal sent by the controller, and calculates the actual opening percentage of the valve of the liquid flow regulating valve 7 corresponding to the real-time flow digital signal sent by the liquid flow digital processor 6.

[0064] When feeding is executed, the first solenoid valve 42 remains open, and the liquid flow regulating valve 7 controls the opening degree to quickly open and execute feeding. When the first ultrasonic liquid level sensor 13 detects that the liquid level in the first air pump tank 1 drops to a position 50 mm away from the bottom of the second air pump tank 2, the controller opens the second solenoid valve 44. The high-pressure gas in the high-pressure gas source device is decompressed by the main air source pressure reducing valve 45 and is input into the second air pump tank 2 through the second gas pipeline 43 to apply pressure to the liquid in the second air pump tank 2, pushing the liquid to flow into the three-way pressure-bearing hose 9. During this process, the first air pump tank 1 and the second air pump tank 2 are fed simultaneously until when the first ultrasonic liquid level sensor 13 detects that the liquid level in the first air pump tank 1 drops to a position 30 mm away from the bottom of the first air pump tank 1, the controller closes the air supply valve of the first solenoid valve 42, opens the exhaust valve to release pressure, and at the same time opens the first liquid injection solenoid valve 33 to inject the liquid material.

[0065] The first air pump tank 1 and the second air pump tank 2 supply materials alternately and continuously as in the above feeding process.

[0066] When any ultrasonic liquid level sensor detects that the liquid level in the corresponding air pump tank does not reach 60 mm away from the top cover and lasts for 120 seconds, the controller will determine that the feeding is over. The first liquid injection solenoid valve 33 and the second liquid injection solenoid valve 34 are closed to ensure that both the first solenoid valve 42 and the second solenoid valve 42 are in the open state, and the liquid flow regulating valve 7 continues to maintain the production-set opening degree until the liquid flow detector 5 detects an empty pipe signal. After being processed by the liquid flow digital processor 6, the controller closes the first solenoid valve 42, the second solenoid valve 42, and the liquid flow regulating valve 7 after timing for 10 seconds to complete the emptying process.

[0067] The above entire control process is programmed by those skilled in the art and input into the controller to complete the entire flavoring process.

[0068] When it is necessary to repair or replace the air pump tank, first disassemble the pipelines on its top cover, manually push the handle body 8441, separate the fixed toothed plate 842 from the moving rack 841, and the moving rack 841 moves downward, causing the connecting piece 83, the first collar 81, the second collar 82, and the first air pump tank 1 and the second air pump tank 2 to move downward synchronously, creating a distance between the top cover and the components such as the pipelines above it. Then, release the handle body 8441, and the fixed toothed plate 842 resets and engages with the moving rack 841 again to be fixed. Under the action of the pin shaft 8433, the operator can rotate the two air pump tanks by a certain angle to completely avoid the components above them. At this time, it is very convenient to repair the two air pump tanks or pull out the two air pump tanks from the two collars for replacement. When the repair or replacement is completed, reverse the above operations to install the two air pump tanks into the two collars and restore them to their original installation positions.

[0069] It should be noted that the above are only the preferred embodiments of the present invention and cannot limit the scope of implementation of the present invention once and for all. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
