[0001] The utility model relates to the technical field of cigarette flavoring experimental devices, in particular to an ejector nozzle atomization effect testing device. Background Art

[0002] The tobacco industry uses a feeding device to add a certain proportion of flavor liquid to the tobacco material. The liquid is pumped from the material tank by the feeding pump and sent to the nozzle. Under the action of the induced steam, it is sprayed on the tobacco material in the form of mist.

[0003] The atomization effect of the nozzle is related to the liquid flow rate, the injection pressure and the nozzle gap. During use, when the liquid flow rate changes while the nozzle gap remains unchanged, the atomization effect will deteriorate. The injection pressure needs to be adjusted accordingly to improve the atomization effect of the nozzle.

Therefore, the terms describing the positional relationships in the figures are only used for illustrative purposes and cannot be understood as limitations on the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] like Figure 1-Figure 2 As shown, the present invention is a device for testing the atomization effect of an ejector nozzle, comprising a movable platform 1 and a liquid feed pipeline 2, a first ejector pipeline 3, a second ejector pipeline 4 and a nozzle 5 installed on the movable platform 1.

[0031] In this embodiment, one end of the liquid feed pipeline 2 is connected to the nozzle 5, and the other end is connected to the material tank 21. The liquid feed pipeline 2 is connected to a flow meter 22 and a pump 23. The flow meter 22 is used to measure the flow rate of the liquid feed in the liquid feed pipeline 2, and the pump 23 is used to pump the liquid feed in the material tank 21 to the nozzle 5. By changing the pumping force of the pump 23, the flow rate of the liquid feed can be changed, thereby changing the value of the flow meter 22.

[0032] In this embodiment, the first ejection line 3 is connected to the nozzle 5 at one end and to the first ejection source 31 at the other end. The second ejection line 4 is connected to the nozzle 5 at one end and to the second ejection source 41 at the other end. In this embodiment, the first ejection source 31 is a steam source, and the second ejection source 41 is a compressed air source. The appropriate ejection line can be selected based on actual conditions. In other embodiments, only the first ejection line 3 may be provided, but switching ejection sources poses certain safety risks. The first ejection line 3 is connected to a first pressure gauge 32 and a first pneumatic valve 33, which is used to change the reading on the first pressure gauge 32. The second ejection line 4 is connected to a second pressure gauge 42 and a second pneumatic valve 43, which is used to change the reading on the second pressure gauge 42. During testing, the appropriate ejection line can be selected based on actual conditions. Taking the steam injection source of the first injection line 3 as an example, the pump 23 is operated while the flow meter 22 reading remains unchanged. The steam pressure in the first injection line 3 is then adjusted by varying the opening of the first pneumatic valve 33 and adjusting the first pressure gauge 32 until a satisfactory atomization effect is achieved. The corresponding value of the first pressure gauge 32 at this point is recorded. Subsequently, the pumping force of the pump 23 is varied, the flow meter 22 reading is altered, and the first pressure gauge 32 reading is again adjusted until a satisfactory atomization effect is achieved. The corresponding value of the first pressure gauge 32 at this point is recorded. This process is repeated to obtain injection pressure values ​​that match different feed flow rates. Similarly, when selecting the second injection line 4, the operating principle is the same. It is understood that injection pressure values ​​that match different feed flow rates can be obtained for different feed types. In this embodiment, the pump 23, the first pneumatic valve 33, and the second pneumatic valve 43 can be controlled by a PLC controller or by independent controllers.

[0033] In this embodiment, a receiving mechanism is provided at one end of the nozzle 5, which is used to receive the atomized liquid sprayed from the nozzle 5. The atomized liquid sprayed from the nozzle 5 can be adsorbed on the receiving mechanism, making it easy to observe the size and uniformity of the atomized particles and to judge whether the atomization effect is good.

[0034] In the present embodiment, the receiving mechanism includes a frame 61, a rolling belt 62 and a driving assembly 63. The frame 61 includes a receiving area 611 and a display area 612. The rolling belt 62 is tensioned on the frame 61 by a plurality of guide rollers 621. The driving assembly 63 is used to drive the rolling belt 62 to move from the receiving area 611 to the display area 612. In some other embodiments, the receiving mechanism can also be set to glass, cardboard, etc. In the present embodiment, by setting the rolling belt 62, the atomized liquid can be continuously sprayed on the surface of the rolling belt 62, which is convenient for observing the stability of the atomization effect. It can also avoid an unstable atomization state after adjustment, which affects the judgment of the atomization effect. In the present embodiment, the driving assembly 63 is a driving motor, and the output shaft of the driving motor is connected to one of the guide rollers 621 of the plurality of guide rollers 621 by a transmission belt.

[0035] In this embodiment, the frame 61 includes a cleaning area 613. A cleaning roller 64 is rotatably provided at one end of the cleaning area 613 away from the receiving area 611. A bracket 641 is provided between the cleaning roller 64 and the mounting frame. The bracket 641 is fixedly connected to the frame 61, and the cleaning roller 64 is rotatably connected to the bracket 641. The cleaning roller 64 is used to clean the liquid on the surface of the rolling belt 62. A drying roller 65 is rotatably provided at one end of the cleaning area 613 near the receiving area 611. The drying roller 65 is used to absorb the liquid remaining on the surface of the rolling belt 62. The cleaning roller 64 cleans the liquid adsorbed on the rolling belt 62, and the drying roller 65 absorbs the liquid remaining on the surface of the rolling belt 62, thereby ensuring the recycling of the rolling belt 62.

[0036] In this embodiment, the frame 61 is provided with a support plate at the receiving area 611 , and the support plate is used to support the rolling belt 62 in the receiving area 611 to ensure the flatness of the rolling belt 62 in the receiving area 611 .

[0037] The working principle of this utility model is as follows:

[0038] Take the steam injection source of the first injection pipeline 3 as an example:

[0039] First, the rolling belt 62 is driven by the driving motor to move in a circular motion.

[0040] Then, the pump 23 is controlled to work and the value of the flow meter 22 is kept unchanged. Steam is continuously introduced into the first ejection pipe 3 and merged with the liquid at the nozzle to be atomized through the nozzle.

[0041] Subsequently, by changing the opening of the first pneumatic valve 33, adjusting the size of the first pressure gauge 32, and adjusting the steam pressure of the first injection pipeline 3, until the size of the adsorption liquid particles on the rolling belt 62 is suitable and uniform, and the atomization effect reaches a good state, record the value of the first pressure gauge 32 corresponding to the flow meter 22 at this time.

[0042] Finally, repeat the above steps to obtain the injection pressure values ​​that match different liquid flow rates.

[0043] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and such modifications or equivalent substitutions shall be encompassed by the claims of the present invention. The techniques, shapes, and structural portions not described in detail in the present invention are well known.
