Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of oil atomization, in particular to an electronic atomization system and an atomization processing method. BACKGROUND

[0002] Most of the existing electronic atomization devices heat the aerosol generating medium to a boiling state by using a ceramic or cotton core as an electric heating element and adopting heat conduction to realize atomization. Since the boiling point of the aerosol generating medium is relatively high, the aerosol generating medium undergoes a high-temperature heating process on the electric heating element. However, the high temperature of the electric heating element may cause some effective components contained in the aerosol generating medium to decompose and deteriorate at high temperatures, resulting in changes in the aroma and smoke of the aerosol, directly affecting the smoking quality and the product use experience. In addition, long-term use may cause the materials of the electric heating element or the oil guide element to crack, fall off, carbonize or dissolve out, which may pose potential health risks.

[0049] 5、The atomization treatment method provided by the application preheats the aerosol generating medium before colliding and mixing the high-pressure airflow with the aerosol generating medium, and controls the temperature of the aerosol generating medium supplied to the jet atomization module to be between 80 DEG C and 150 DEG C. Since the minimum boiling point of the effective components such as essence and spices in the aerosol generating medium is 150 DEG C, the preheating temperature is lower than 150 DEG C, which can ensure that the essence and spices do not volatilize during the preheating process, and ensure the aroma quality at the atomization outlet. At the same time, the preheating temperature is controlled to be higher than 80 DEG C, which can reduce the viscosity of the aerosol generating medium from 200 Cp at room temperature to 20 Cp at 80 DEG C, and the viscosity is greatly reduced, which is beneficial to atomization.

[0077] In addition, the technical features involved in the different embodiments of the application described below can be combined with each other as long as there is no conflict between them.

[0078] Example One

[0079] As Figures 1 to 13 shown, the present embodiment provides an electronic atomization system, which comprises a gas supply module 10, a liquid supply module 20 and a jet atomization module 30, the gas supply module 10 is adapted to provide a high-pressure gas flow, the liquid supply module 20 is adapted to provide an aerosol generating medium; the jet atomization module 30 is adapted to collide and mix the high-pressure gas flow and the aerosol generating medium, so as to use the shear force generated by the speed difference between the high-pressure gas flow and the aerosol generating medium to shear and break the aerosol generating medium to form atomized particles.

[0080] The present embodiment uses high-speed gas assisted atomization, uses the speed difference between high-speed gas and aerosol generating medium to shear and break the aerosol generating medium, the whole atomization process is without phase change, and is always at a lower temperature for atomization, without the phenomenon of partial components of the aerosol generating medium being decomposed and deteriorated due to high temperature, with very high reduction, and without safety problems, higher safety, which can effectively avoid the defects of low safety, poor reduction and easy production of burnt smell caused by the high-temperature heating atomization method of the existing electronic atomization device.

[0081] In this embodiment, the jet atomization module 30 is the core part of the entire atomization system. The principle of jet atomization is that the high-pressure airflow has an extremely high velocity, generally greater than 200 m / s, while the velocity of the aerosol generating medium is 0.01 to 0.1 m / s, which can be ignored. The velocity difference between the high-pressure airflow and the aerosol generating medium is used to shear the aerosol generating medium. After the shearing force overcomes the viscosity and surface tension of the aerosol generating medium, the aerosol generating medium will break down into particles with a diameter of less than 10 μm, forming atomized particles.

[0082] In this embodiment, the jet atomization module 30 uses internal mixing and external mixing to mix the aerosol generating medium and high-speed, high-pressure air. The two mixing methods are described in detail below.

[0083] like Figures 2 to 6 As shown, in one embodiment of this example, the jet atomization module 30 uses an external mixing method for jet atomization.

[0084] Specifically, such as Figure 2 and Figure 3 As shown, the jet atomization module 30 includes a first jet nozzle 31 and a second jet nozzle 32. The inlet end of the first jet nozzle 31 is connected to the air supply module 10, and its outlet end is adapted to eject a high-speed airflow jet. The inlet end of the second jet nozzle 32 is connected to the liquid supply module 20, and its outlet end is adapted to eject an aerosol generating medium jet. The airflow jet from the first jet nozzle 31 and the aerosol generating medium jet from the second jet nozzle 32 form a set angle and collide and mix with each other to form atomized particles.

[0085] Optionally, the set included angle is between 0 and 90°.

[0086] Optionally, in the above embodiments, such as Figure 2 and Figure 4 As shown, there are multiple second jet nozzles 32 arranged around the first jet nozzle 31. By using multiple second jet nozzles 32, the liquid output can be increased, thereby improving the atomization efficiency. Preferably, there are two second jet nozzles 32, symmetrically arranged on both sides of the first jet nozzle 31.

[0087] Alternatively, in another variation, there may be multiple first jet nozzles 31, and one or more corresponding second jet nozzles 32.

[0088] In this embodiment, the jet atomization module 30, by adopting the above-described structural design, enables the high-pressure gas to form a single or multiple jets of airflow, and the aerosol generating medium to form a single or multiple jets of aerosol generating medium.

[0089] Alternatively, in another variant, as shown in Figure 2 and Figure 5 The second jet nozzle 32 is in the form of an annular structure arranged around the first jet nozzle 31. The second jet nozzle 32 has an annular jet chamber with a plurality of jet outlets arranged thereon at intervals, which jet outlets jet the aerosol generating medium beam towards the center, so as to collide and mix with the high-speed airflow beam jetted by the first jet nozzle 31, thereby realizing jet atomization.

[0090] In another variant, as shown in Figure 2 and Figure 6 The second jet nozzle 32 and the first jet nozzle 31 are both in the form of an annular structure, and there are at least two of each. The second jet nozzle 32 and the first jet nozzle 31 are designed in the form of a sleeve ring structure arranged alternately from the inner line to the outer layer. Due to the sleeve ring design, the inner and outer sides of the aerosol generating medium are sheared, thereby improving the atomization efficiency.

[0091] In the above-mentioned scheme, the high-speed airflow beam and the aerosol generating medium beam can be in the form of a cylinder or a circular ring or other special-shaped ring structure, and the equivalent diameter of the airflow beam and the aerosol generating medium beam ranges from 0.1 mm to 1 mm.

[0092] The external mixing jet atomization provided by the embodiment is that the high-pressure gas and the aerosol generating medium are jetted out through their respective nozzles and then mixed. The first jet nozzle 31 and the second jet nozzle 32 each have a separate jet outlet, and the high-speed airflow beam and the aerosol generating medium beam exchange momentum and then break up.

[0093] Optionally, the jet outlet is a fine hole with a diameter less than or equal to 0.5 mm. The size of the hole diameter directly affects the jet effect and the gas and liquid supply pressure. The larger the hole diameter, the worse the atomization effect, and the greater the gas and liquid supply pressure. Therefore, in the embodiment, the hole diameter of the jet outlet is less than or equal to 0.5 mm, which can ensure sufficient atomization effect and reduce the gas and liquid supply pressure.

[0094] As shown in Figure 7 and Figure 8 In another embodiment of the embodiment, the jet atomization module 30 adopts an internal mixing mode for jet atomization.

[0095] Specifically, as shown in Figure 7As shown, the jet atomization module 30 comprises an atomization cavity 301 and a jet orifice 331 formed on the atomization cavity 301, the atomization cavity 301 is in communication with the gas supply module 10 and the liquid supply module 20 respectively, the aerosol generating medium introduced into the atomization cavity 301 is mixed with the high-pressure gas flow to form atomized particles; the jet orifice 331 is in communication with the inside and outside of the atomization cavity 301, and is suitable for spraying the atomized particles formed in the atomization cavity 301.

[0096] Further, the jet atomization module 30 comprises an atomization seat 33, an air inlet channel 332 and a liquid inlet plug 34, the atomization seat 33 has an atomization cavity 301 with an open top; the air inlet channel 332 is formed on the peripheral wall of the atomization seat 33 and is suitable for introducing a high-pressure gas flow into the atomization cavity 301; the liquid inlet plug 34 is inserted into the atomization seat 33 and has a hollow liquid inlet channel 341 in the inside, the upper end of the liquid inlet plug 34 is in interference fit with the atomization seat 33 and is in communication with the liquid supply module 20, and the lower end of the liquid inlet plug 34 is in clearance fit with the atomization seat 33 and is in communication with the atomization cavity 301.

[0097] In the above scheme, the atomization seat 33 has a cylindrical peripheral wall, the liquid inlet plug 34 is configured as a hollow columnar structure, the liquid inlet plug 34 comprises an interference section 342 and a non-interference section 343 with a reduced outer diameter, wherein the outer diameter of the interference section 342 is greater than the inner diameter of the cylindrical peripheral wall, the outer diameter of the non-interference section 343 is smaller than the inner diameter of the cylindrical peripheral wall, and the interference section 342 is located at the upper part of the atomization seat 33 and is in interference fit with the inner peripheral wall of the atomization seat 33 to close the open top of the atomization cavity 301.

[0098] Preferably, the upper end of the interference section 342 is provided with an annular blocking boss 344 in the circumferential direction, the blocking boss 344 blocks the open top edge of the atomization seat 33 to prevent gas or atomized particles from escaping through the gap between the liquid inlet plug 34 and the atomization seat 33, further ensuring the sealing of the atomization cavity 301.

[0099] Preferably, the inner circumferential side of the open top edge of the atomization seat 33 is further formed with an annular clamping boss 333, and the outer periphery of the interference section 342 is correspondingly recessed to form an annular clamping groove, after the liquid inlet plug 34 is inserted into the atomization seat 33, the annular clamping boss 333 is clamped in the annular clamping groove, realizing the clamping fit of the atomization seat 33 and the liquid inlet plug 34, improving the stability of the fit of the atomization seat 33 and the liquid inlet plug 34, and further improving the sealing effect of the atomization cavity 301.

[0100] Optionally, in the present embodiment, the upper part of the interference section 342 is further connected with a connecting section suitable for connecting with the liquid supply module 20, and the outer diameter of the connecting section is smaller than the outer diameter of the interference section 342.

[0101] Further, in the embodiment, the non-interference section 343 of the liquid inlet plug 34 includes a cylindrical portion and a tapered tip portion. The non-interference section 343 can increase the available space of the atomization cavity 301 in a limited space by adopting the structure design of the tapered tip portion, thereby improving the atomization efficiency.

[0102] Optionally, in the embodiment, the jet orifice 331 is configured on the bottom wall of the atomization seat 33. Of course, the jet orifice 331 can also be configured on the peripheral wall of the atomization seat 33. The embodiment does not limit the position of the jet orifice 331, as long as the jet orifice 331 can communicate with the atomization cavity 301 and ensure that the atomized particles in the atomization cavity 301 can be sprayed out of the jet orifice 331.

[0103] Further, the jet orifice 331 includes a cylindrical aperture section and a tapered aperture section. The cylindrical aperture section is located on the side close to the atomization cavity 301, and the aperture of the cylindrical aperture section is less than or equal to 0.5 mm. The tapered aperture section is located on the side away from the atomization cavity 301, and the aperture of the tapered aperture section gradually increases from the direction in which the atomized particles are sprayed out, so that the atomized particles are sprayed outwards in a divergent manner.

[0104] Optionally, from the direction in which the aerosol generating medium enters, the liquid inlet channel 341 includes a first cylindrical aperture section, a tapered reduced-diameter section, and a second cylindrical aperture section connected in sequence. The aperture of the second cylindrical aperture section is smaller than that of the first cylindrical aperture section. By adopting the above structure design, the pressure of the aerosol generating medium in the liquid inlet channel 341 can be improved.

[0105] Optionally, the first cylindrical aperture section is formed in the interference section 342, and the tapered reduced-diameter section and the second cylindrical aperture section are formed in the non-interference section 343.

[0106] Preferably, in combination with the structures shown in Figure 7 and Figure 8 , the aperture of the second cylindrical aperture section is less than or equal to 0.5 mm, and the outlet of the second cylindrical aperture section is directly opposite the jet orifice 331 and has a set gap H with the jet orifice 331. Preferably, the set gap H is 0.1 mm. Since the high-pressure airflow in the atomization cavity 301 will converge at the jet orifice 331 under the action of pressure difference, by adopting the above structure design, the aerosol generating medium flowing out of the liquid inlet channel 341 can be sheared and broken into atomized particles by a large amount of high-pressure and high-speed airflow at the jet orifice 331, thereby improving the breaking effect of the aerosol generating medium, so that the diameter of the atomized particles is reduced, and the atomization effect is better.

[0107] Optionally, the cylindrical peripheral wall comprises a clearance fit section adapted to clearance fit with the liquid inlet plug 34, and a plurality of air inlet channels 332 are formed on the outer periphery of the clearance fit section of the cylindrical peripheral wall and are arranged in a circumferentially spaced manner along the cylindrical peripheral wall.

[0108] Optionally, the air inlet channel 332 is a hollow tubular structure integrally formed on the outer peripheral wall of the atomization seat 33, and preferably, there are two air inlet channels 332 symmetrically arranged on the peripheral wall of the atomization seat 33. More preferably, the central axis of the air inlet channel 332 is arranged at an angle of 90° with the central axis of the atomization seat 33.

[0109] Optionally, the gap between the outer diameter of the non-interference section 343 of the liquid inlet plug 34 and the inner peripheral wall of the atomization seat 33 is less than or equal to 0.5 mm, and preferably equal to 0.5 mm. With such a design, when the high-pressure gas enters the inside of the atomization cavity 301 from the narrow gap, a larger pressure can be formed, the gas flow rate can be increased, and thus the shear force on the aerosol generating medium can be increased, and the atomization effect can be improved.

[0110] Optionally, as shown in Figure 1 the electronic atomization system of the present embodiment further comprises a preheating module 40 arranged between the liquid supply module 20 and the jet atomization module 30 and adapted to preheat the aerosol generating medium supplied to the jet atomization module 30.

[0111] The electronic atomization system of the present embodiment preheats the aerosol generating medium by the preheating module 40 arranged between the liquid supply module 20 and the jet atomization module 30, and the preheated aerosol generating medium is then supplied to the jet atomization module 30, thereby reducing the viscosity of the aerosol generating medium supplied to the jet atomization module 30, and significantly improving the breaking effect of the aerosol generating medium during jet atomization, reducing the diameter of the atomized particles, and improving the atomization effect.

[0112] As shown in Figure 12 , the 25℃ aerosol generating medium before preheating still has a significant stringing phenomenon, as shown in Figure 13 , the 60℃ aerosol generating medium after preheating is obviously in a misty state. In combination with Figure 1 and Figure 11 , the present embodiment preheats the aerosol generating medium by the preheating module 40, and when the temperature is less than 80℃, the viscosity of the aerosol generating medium decreases significantly with the increase of the temperature. By preheating the aerosol generating medium by heating, the maximum temperature of the preheating module 40 is <150℃, which avoids the volatilization of the effective components in the aerosol generating medium, and at the same time, the temperature of the tobacco tar supplied to the jet atomization system is controlled to be >80℃, which can ensure that the viscosity of the aerosol generating medium is reduced from 200Cp at room temperature to below 50Cp.

[0113] In addition, due to the high gas flow rate, the aerosol generating medium is obviously cooled, and the air is preheated, thereby reducing the heat exchange between the air and the aerosol generating medium and ensuring the temperature of the atomization outlet 80 of the aerosol generating medium.

[0129] Example Two

[0130] In combination Figures 1 to 13 The embodiment shown provides an atomization processing method applied to the electronic atomization system of the above embodiment one, and the method comprises the following steps:

[0131] The high-pressure airflow collides with the aerosol generating medium for mixing;

[0132] The shear force generated by the speed difference between the high-pressure airflow and the aerosol generating medium is used to shear and break the aerosol generating medium to form atomized particles.

[0133] Optionally, the following steps are performed before the high-pressure airflow collides with the aerosol generating medium for mixing:

[0134] The aerosol generating medium is preheated, and the temperature of the aerosol generating medium supplied to the jet atomization module 30 is controlled to be between 80℃ and 150℃;

[0135] The gas flow rate is controlled to be between 100m / s and 340m / s.

[0136] The atomization processing method provided by the embodiment preheats the aerosol generating medium before the high-pressure airflow collides with the aerosol generating medium for mixing, and controls the temperature of the aerosol generating medium supplied to the jet atomization module 30 to be between 80℃ and 150℃. Since the minimum boiling point of the effective components such as flavoring spices in the aerosol generating medium is 150℃, preheating at a temperature lower than 150℃ can ensure that the flavoring spices do not volatilize during preheating, ensuring the aroma quality at the atomization outlet 80. At the same time, controlling the preheating temperature to be higher than 80℃ can reduce the viscosity of the aerosol generating medium from 200Cp at room temperature to 20Cp at 80℃, which is a large decrease in viscosity and is conducive to atomization.

[0137] Optionally, the following steps are performed after the atomized particles are formed:

[0138] The atomized particles are collected and slowed down, and the atomized particles are heated again.

[0139] The atomization treatment method provided by the embodiment adopts a jet flow atomization mode for low-temperature atomization, and utilizes gas-assisted crushing. The crushing principle is the speed difference between the high-speed airflow and the aerosol generating medium (wherein the speed of the liquid aerosol generating medium is 0.01-0.1 m / s, which can be ignored, and the gas flow rate is 100-340 m / s, which is the speed difference), a relatively large shear force is generated to shear and crush the aerosol generating medium. The entire atomization process does not change phase, and is always atomized at a relatively low temperature, and the phenomenon that part of the components of the aerosol generating medium are decomposed and deteriorated due to high temperature does not occur, the reduction is extremely high, and it is safer.

Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments cannot be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the present application.
