[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0045] Based on the above technical problems, an embodiment of the present application provides an electronic atomization device 100, which includes a shell 110, in which a battery core 191 and an atomization core 120 for atomizing a liquid matrix to generate an aerosol are disposed.

[0046] Specifically, in this embodiment, if Figure 1-Figure 3As shown, the atomization core 120 may include a liquid absorption surface 131 for absorbing liquid matrix, an atomization surface 132 arranged opposite to the liquid absorption surface 131, and a connecting surface 133 arranged between the liquid absorption surface 131 and the atomization surface 132; wherein the atomization surface 132 is arranged facing a side wall of the shell 110 along the width or thickness direction of the electronic atomization device 100.

[0047] It is understandable that in this embodiment, since the atomizing surface 132 can be arranged facing a side wall of the shell 110 along the width or thickness direction of the electronic atomizing device 100, the atomizing core 120 can be placed vertically in the shell 110 to adapt to more internal structural forms of the electronic atomizing device 100 and correspond to the development trend of electronic atomizing technology. At the same time, the vertical arrangement of the atomizing core 120 in the shell 110 can also optimize the lateral space in the width direction or thickness direction of the electronic atomizing device 100, and can improve the passing efficiency of the aerosol at the atomizing core 120 by reducing the contact area between the atomizing core 120 and the aerosol, and further improve the atomization performance of the atomizing core 120.

[0048] It should be noted that in the embodiments of the present application, Figure 2 As shown, the housing 110 may include a first side wall 118 and a second side wall 119 arranged along the width direction or the thickness direction of the electronic atomization device 100, wherein the atomization surface 132 can be arranged facing the first side wall 118 or the second side wall 119; at the same time, in other embodiments of the present application, such as Figure 3 As shown, the atomizing core 120 may include a porous body 130, and the liquid absorption surface 131, the atomizing surface 132 and the connecting surface 133 may all be arranged on the porous body 130. At the same time, the porous body 130 may be made of a hard capillary structure such as porous ceramics, porous glass ceramics, porous glass, etc., and has a large number of microporous structures inside, so that the liquid matrix absorbed on the liquid absorption surface 131 can be transferred to the atomizing surface 132 through the microporous structure for heating and atomization. In addition, in order to ensure the oil conduction efficiency of the porous body 130, the thickness of the porous body 130 in this embodiment does not exceed 2 mm.

[0049] At the same time, in this embodiment, an electrode 140 is further provided on the connecting surface 133, and an electrode column 160 may also be provided in the shell 110, wherein one end of the electrode column 160 is electrically connected to the battery cell 191, and the other end maintains contact with the electrode 140 on the connecting surface 133 to form an electrical connection, so that the atomization core 120 can be supported by the electrode column 160, so as to further improve the stability of the assembly of internal components of the electronic atomization device 100.

[0050] It should be noted that, in further embodiments, Figure 2As shown, the electrode column 160 can extend along the longitudinal direction of the electronic atomization device 100 to provide a better supporting effect for the atomization core 120 .

[0051] In some embodiments, Figure 2 and Figure 3 As shown, the atomizing core 120 may further include a heating element 150 disposed on the atomizing surface 132, and the electrode 140 extends from the connecting surface 133 to the atomizing surface 132 to form an electrical connection with the heating element 150, thereby achieving the purpose of energizing the heating element 150 to heat the atomized liquid matrix and form an aerosol.

[0052] In other embodiments of the application, Figure 2 and Figure 3 As shown, the heating element 150 may include a heating circuit 151, and the electrode 140 may include a first electrode structure 141 and a second electrode structure 142, wherein the first electrode structure 141 and the second electrode structure 142 are respectively arranged at both ends of the porous body 130, so as to ensure that the connection area of ​​the expanded electrode column 160 is ensured, and the cost of manufacturing the electronic atomization device 100 can be further saved by reducing the arrangement amount of the electrode 140 structure. At the same time, the heating circuit 151 is electrically connected to the first electrode structure 141 and the second electrode structure 142, respectively.

[0053] It should be noted that, in the above-mentioned embodiment, the first electrode structure 141 and the second electrode structure 142 can be respectively coated at the first end 134 and the second end 135 in the form of a coating, so as to further optimize the overall volume of the atomizer core 120; at the same time, the specific preparation materials of the first electrode structure 141 and the second electrode structure 142 are not limited in this embodiment, for example, it can be one or more of the electrode 140 materials such as stainless steel, copper-based alloy, aluminum alloy or titanium alloy.

[0054] In some embodiments, Figure 2 As shown, a bracket 111 may be provided in the shell 110, and a liquid storage cavity 1111 for storing a liquid matrix is ​​defined in the bracket 111. At the same time, a mounting hole 1112 is provided on one side of the bracket 111 close to the first side wall 118. The mounting hole 1112 is used to mount the atomizer core 120, and the liquid absorption surface 131 is also arranged facing the liquid storage cavity 1111, so that the liquid matrix in the liquid storage cavity 1111 can be directly transferred to the liquid absorption surface 131 of the atomizer core 120, so as to further improve the atomization efficiency of the atomizer core 120.

[0055] For further information, please refer to Figure 2In the above embodiment, the mounting hole 1112 is arranged near the bottom of the bracket 111, and the bottom is inclined toward the mounting hole 1112 (at this time, the atomizer core 120 is located at the lowest point of the bottom), so that the liquid matrix in the liquid storage cavity 1111 can flow in a direction close to the liquid absorption surface 131, so that the liquid matrix in the liquid storage cavity 1111 can fully contact the liquid absorption surface 131, thereby further improving the atomization performance of the atomizer core 120.

[0056] It should be noted that in other embodiments of the present application, Figure 2 As shown, a first sealing member 112 and a cover plate 192 may also be provided in the housing 110 , wherein the first sealing member 112 is provided between the atomizer core 120 and the mounting hole 1112 , and the cover plate 192 is covered on the bracket 111 to achieve the purpose of sealing the liquid storage chamber 1111 .

[0057] In addition, in further embodiments, see Figure 2 Combined with Figure 4 and Figure 5 A plurality of liquid guiding grooves 1113 may be formed on one side of the bottom facing the liquid storage chamber 1111, and the plurality of liquid guiding grooves 1113 are arranged one by one at intervals, so that the liquid medium in the liquid storage chamber 1111 can be dispersedly transferred to the liquid absorption surface 131 along the liquid guiding grooves 1113, so that the liquid matrix can be more evenly transferred to the liquid absorption surface 131.

[0058] In some embodiments, see Figure 2 Combined with Figure 6 An opening 170 communicating with the liquid storage chamber 1111 may be provided on the side of the bottom facing away from the liquid storage chamber 1111, and a ventilation valve 180 is provided at the opening 170. A ventilation channel 1831 is formed in the gap between the ventilation valve 180 and the wall forming the opening 170 to enable ventilation between the liquid storage chamber 1111 and the external air.

[0059] It should be noted that, in this embodiment, when the atomizer core 120 consumes the liquid matrix in the liquid storage chamber 1111, negative pressure will be generated in the liquid storage chamber 1111. At this time, external gas can enter the interior of the liquid storage chamber 1111 through the ventilation channel 1831 (such as Figure 6 The air flow direction is indicated by the arrow to balance the air pressure inside the bracket 111. It is understandable that whenever the liquid matrix inside the liquid storage chamber 1111 is consumed, the air pressure can be compensated through the ventilation channel 1831, so as to achieve the effect of smooth liquid flow in the liquid storage chamber 1111.

[0060] For further information, please refer to Figure 6The ventilation valve 180 includes a base 181 and a boss 182 formed on the base 181, wherein the boss 182 is inserted into the opening 170, and a ventilation groove 184 is formed on the outer surface of the boss 182, and the ventilation groove 184 and the wall forming the opening 170 together form a ventilation channel 1831. At the same time, an air inlet 113 and an air outlet 114 are opened at both ends of the shell 110, wherein the ventilation channel 1831 is connected with the air inlet 113, thereby achieving the purpose of connecting the liquid storage chamber 1111 with the outside air.

[0061] In some embodiments, see Figure 2 Combined with Figure 6 A protrusion 183 may also be formed on the circumference of the base 181, wherein the protrusion 183 and the boss 182 are arranged at intervals, and a liquid storage tank 185 is defined between the protrusion 183 and the boss 182. At the same time, the liquid storage tank 185 is connected to the ventilation channel 1831 and is used to store the liquid matrix leaked from the ventilation channel 1831. It can be understood that in this embodiment, when the air inside the liquid storage chamber 1111 reaches a certain volume, the gas volume inside the liquid storage chamber 1111 will expand or contract due to the temperature difference. When the gas volume inside the liquid storage chamber 1111 expands, a small amount of liquid matrix in the liquid storage chamber 1111 will be squeezed out through the ventilation channel 1831. At this time, the liquid storage tank 185 can store these squeezed liquid matrices. When the gas volume inside the liquid storage chamber 1111 shrinks, the liquid matrix stored in the liquid storage tank 185 can enter the liquid storage chamber 1111 through the ventilation channel 1831, thereby preventing the liquid storage chamber 1111 from leaking.

[0062] In some embodiments, Figure 2 As shown, an air flow channel 115 connected to the air outlet 114 is also provided in the shell 110, and the air flow channel 115 extends along the longitudinal direction of the electronic atomization device 100 and passes between the atomization surface 132 and the side wall; at the same time, the air flow channel 115 is located on one side of the liquid storage chamber 1111, and the atomization core 120 is located between the air flow channel 115 and the liquid storage chamber 1111, so that the external air entering from the air inlet 113 can flow through the air flow channel 115 and flow to the air outlet 114 in a roughly straight line, thereby reducing the number of air flow turns to avoid condensation of aerosol generated by heated atomization, thereby further improving the utilization rate of the liquid matrix.

[0063] In a further embodiment, the distance between the atomizing surface 132 and the wall forming the air flow channel 115 is between 2 mm and 5 mm.

[0064] In some embodiments, Figure 2As shown, a retaining member 116 for retaining the battery cell 191 is further provided in the shell 110, wherein the retaining member 116 is provided with an air outlet channel 1161, and the air flow channel 115 extends from the air outlet channel 1161 to the air outlet 114, so that the outside air can flow through the air inlet 113 and the air outlet channel 1161, and is heated and atomized by the atomization core 120 that receives the liquid matrix to generate an aerosol, and the generated aerosol can flow through the air flow channel 115 and finally flow out from the air outlet 114, so as to further reduce the number of air flow turns, thereby further improving the utilization rate of the liquid matrix.

[0065] In some embodiments, Figure 2 As shown, a second seal 117 may also be provided in the shell 110, and the second seal 117 is provided between the air outlet 114 and the air outlet channel 1161, so as to avoid the problem of condensation water generated by the aerosol generated by heating and atomization contacting with the normal temperature air in the shell 110.
