Description

Technical Field

[0001] The utility model relates to the field of atomization equipment, in particular to an aerosol generator. Background Art

[0002] Most existing aerosol generators utilize a heating wire or tube for atomization. Atomizer flows into the heating wire or tube, where it is heated, forming a high-temperature gaseous atomizer. Under pressure, external cooling air enters the aerosol generator and mixes with the high-temperature gaseous atomizer. The high-temperature gaseous atomizer then rapidly condenses upon contact with the external cooling air, forming mist. However, since external cooling air typically enters the aerosol generator through an air inlet and blows toward the heating wire at its base, this can easily lead to atomizer leakage from the air inlet. Furthermore, the lack of cooling air at the top of the heating wire causes uneven heat dissipation, making it prone to overheating and burning, thus affecting the heating of the atomizer.

[0033] The embodiment of the present invention provides an aerosol generator 100. The aerosol generator 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0034] See also Figures 1 to 7 The aerosol generator 100 includes a shell and an atomizing assembly 10. The shell includes a base 20 and an outer shell 30. The bottom of the outer shell 30 is in contact with the base 20 and together they form a liquid storage tank 50. The liquid storage tank 50 is used to store the atomizer.

[0035] The atomizing assembly 10 is accommodated in the housing 30 , and includes an atomizing portion 11 , a substrate 12 located at the bottom of the atomizing portion 11 , a top cover 13 located at the top of the atomizing portion 11 , and a heating device 14 located in the atomizing portion 11 .

[0036] See also Figures 3 to 6 , the atomizing portion 11 is respectively provided with an atomizing bin 111 and a mist outlet channel 112 located at the top of the atomizing bin 111. The atomizing agent is heated and atomized by the heating device 14 in the atomizing bin 111 and can be discharged from the mist outlet channel 112. In an embodiment of the present utility model, the inner wall of the atomizing bin 111 is roughly truncated cone-shaped, and the inner wall of the mist outlet channel 112 is roughly cylindrical. The inner diameter of the mist outlet channel 112 is smaller than the top diameter of the atomizing bin 111, and a baffle 113 is protruded from its bottom toward the atomizing bin 111. Such a setting can prevent the atomizing agent in the atomizing bin 111 from being sprayed out due to lack of time for heating.

[0037] The atomizing unit 11 is provided with a through hole 114 at the connection with the top cover 13, and the mist outlet channel 112 is connected to the through hole 114. When the aerosol generator 100 is in operation, the atomizing agent is heated and atomized by the heating device 14. The mist in the atomizing unit 11 and the high-temperature liquid atomizing agent form a mixed mist that can be discharged from the mist outlet channel 112 and the through hole 114.

[0038] See also Figure 1 and Figure 5 The bottom of the substrate 12 is provided with an air guide column 121 facing downward. An air inlet 125 is provided in the air guide column 121.

That is, the atomizing agent forms mist after undergoing a "liquid-gas-liquid" physical change in the atomizing section 11. The size of the mist particles and the mist concentration can be adjusted by controlling the airflow speed of the cooling gas. The cooling gas can be air, an inert gas, or carbon dioxide, and other types of gases can also be selected as needed.

[0039] An air outlet channel 131 is provided in the middle of the top cover 13, and the air outlet channel 131 is connected to the through hole 114. The vaporized atomizer can be converted into mist and discharged from the through hole 114 and the air outlet channel 131. A liquid replenishing port 132 is also provided on the top cover 13.

In the embodiment of the present invention, the heating element 143 can be made of a metal with good heat resistance. Specifically, the material of the heating element 143 can be stainless steel, nickel alloy, or tungsten wire. The shape of the heating element 143 can be designed to be one or more of a spiral, tubular, mesh, and sheet shape according to actual conditions.

[0041] Preferably, the heating device 14 further includes an oil guide member 144. In the embodiment of the present utility model, the oil guide member 144 is filled in the gap between the liquid inlet 115 and the heating member 143. The oil guide member 144 can be made of a flexible fiber fabric material with good temperature resistance or a solid material with tiny gaps, so that the atomizer can penetrate from the wetter side (i.e., the liquid storage tank 50) to the drier side (i.e., the atomizing portion 11) through the capillary principle, thereby facilitating heating by the heating member 143. Specifically, the flexible fabric material can be cotton, glass fiber, asbestos and other materials, and the solid material with tiny gaps can be porous ceramics with abundant gaps, diatom mud, gypsum, cement and other materials.

[0042] Preferably, both the positive electrode connecting plate 141 and the negative electrode connecting plate 142 are provided with an air outlet 145, which passes through the substrate 12 and communicates with the air inlet 125.

In the embodiment of the present invention, the air outlet 145 is provided on both sides of the heating element 143. On the one hand, it can prevent the atomizer from leaking from the bottom air inlet 125; on the other hand, it can make the heat dissipation of the heating element 143 more uniform, prevent the heating element 143 from overheating and burning, and better heat the atomizer.

[0043] See also Figures 2 to 7The base 20 is provided with a receiving portion 21 facing the atomizing portion 11, and the substrate 12 is fixed in the receiving portion 21. In the embodiment of the utility model, the receiving portion 21 abuts against the inner wall of the outer shell 30, and the base 20 is connected to the outer shell by gluing. Furthermore, a sealing member 22 is provided at the connection position between the base 20 and the outer shell 30, and the sealing member 22 is used to prevent the atomizer in the liquid storage tank 50 from leaking. An air inlet channel 25 is also provided at the bottom of the base 20, and the air guide column 121 is accommodated in the air inlet channel 25. External cooling air can enter the air inlet 125 of the air guide column 121 through the air inlet channel 25.

On the one hand, this can prevent the atomizer from leaking out from the bottom air inlet 125; on the other hand, it can make the heat dissipation of the heating element 143 more uniform, prevent the heating element 143 from overheating and burning, and can also better heat the atomizer. In addition, the oil supply scheme of the aerosol generator 100 of the present invention adopts the capillary principle. The atomizer in the liquid storage tank 50 is continuously infiltrated into the heating device 14 of the atomization tank 111 under the attraction of the oil guide 144, and the "liquid-gas-liquid" atomization process is continuously repeated, so that the aerosol generator 100 provided by the present invention can ensure the continuous supply of atomizer during the atomization process.
