[0034] An embodiment of the present application provides an electronic atomization device 100, which is used to atomize a liquid matrix to generate an inhalable aerosol, such as Figure 1 As shown, the electronic atomization device 100 includes a shell 10 and a bottom cover 20, which are connected to form an outer shell of the electronic atomization device 100. A nozzle 11 is formed on the shell 10, and a user can inhale aerosol by sucking at the nozzle 11.

[0035] like Figure 2As shown, the nozzle 11 includes a longitudinally extending tubular body 111, the tubular body 111 has an air inlet end and an air outlet end which are relatively arranged, the air inlet end is defined with an air inlet 1111 for aerosol to enter the tubular body 111, and the air outlet end is defined with an air outlet 1112 for aerosol to escape from the electronic atomization device 100, and the user can inhale the aerosol escaping from the air outlet 1112 when inhaling on the nozzle 11.

[0036] Please continue reading Figure 2 , and refer to Figure 3 and Figure 4 A liquid storage member 12 is provided in the shell 10, and the liquid storage member 12 is used to store a nebulizable liquid matrix. The liquid storage member 12 may include flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or include a capillary material with a microporous structure, such as porous ceramics, so that the liquid storage member 12 can store and maintain the nebulizable liquid matrix.

[0037] The liquid storage member 12 has a first end face 121 and a second end face 122 that are arranged opposite to each other in the longitudinal direction of the shell 10, and a first through hole 123 connecting the first end face 121 and the second end face 122. The first through hole 123 is provided with an atomization component 13 and an air guide tube 14. The atomization component 13 is used to atomize the liquid matrix to generate an aerosol, and release the generated aerosol into the first through hole 123. The air guide tube 14 connects the atomization component 13 and the tubular body 111, and further transmits the aerosol generated by the atomization of the atomization component 13 to the tubular body 111.

[0038] The atomization assembly 13 includes a liquid guide member 131 and a heating element 132. The liquid guide member 131 is formed with a second through hole 1311 that runs longitudinally therethrough, so that the liquid guide member 13 has an outer surface 1312 and an inner surface 1313. The heating element 132 is combined on the inner surface 1313. The outer surface 1312 contacts the liquid storage member 12 to absorb the liquid matrix in the liquid storage member 12, and transfers the liquid matrix to the heating element 132 on the inner surface 1313. The heating element 132 heats the liquid matrix and atomizes it to generate an aerosol.

[0039] The liquid guide member 131 may also be made of flexible fibers, such as cotton fibers, non-woven fabrics, glass fiber ropes, etc., or made of porous materials with microporous structures, such as porous ceramics, so that the liquid guide member 131 can absorb the liquid matrix from the liquid storage member 12 and transfer the liquid to the inner surface 1313, and then transfer it to the heating element 132 for heating and atomization. The heating element 132 can be combined with the liquid guide member 131 by printing, deposition, sintering or physical assembly, or wrapped on the liquid guide member 131.

[0040] Please continue reading Figure 2The electronic atomization device 100 includes a battery cell 15 and a main board 16. A controller of the electronic atomization device 100 is disposed on the main board 16. The battery cell 15 and the atomization component 13 are electrically connected to the controller, so that the controller can control the battery cell 15 to provide the atomization component 13 with the electric energy required for heating and atomization. The battery cell 15 can be a rechargeable battery cell or a non-rechargeable battery cell.

[0041] Also, please continue to read Figure 2 The bottom shell 20 is provided with an air inlet 21 for external air to enter the electronic atomization device. When the user inhales on the mouthpiece 11, a negative pressure is generated inside the electronic atomization device 100, thereby prompting the external air to enter the electronic atomization device 100 through the air inlet 21, and flow to the atomization component 13 through the internal air flow channel of the electronic atomization device 100, and then carry the aerosol generated by the atomization of the atomization component 13 through the air guide tube 14 to be transmitted to the tubular body 111, and then escape from the air outlet 1111 in the tubular body 111 for the user to inhale.

[0042] like Figure 2 As shown, the first end surface 121 of the liquid storage member 12 is disposed adjacent to the suction nozzle 11, and the first end surface 121 is formed with a protrusion 1211 extending toward the suction nozzle 11. Figure 5 As shown, the inner wall of the tubular body 111 and the nozzle 11 defines a receiving chamber 112, and at least a portion of the protrusion 1211 is connected to the receiving chamber 112 along the longitudinal direction and avoids the air inlet 1111 of the tubular body 111. Therefore, when the electronic atomization device 100 is inverted, the liquid matrix in the liquid storage member 12 will flow and concentrate on the protrusion 1211, and then drip from the protrusion 1211 into the receiving chamber 112, and the receiving chamber 112 can store the liquid matrix flowing out of the liquid storage member 12. Since the protrusion 1211 avoids the air inlet 1111, the liquid matrix can be prevented from flowing into the tubular body 111 when the electronic atomization device 100 is inverted, thereby preventing the liquid matrix from leaking through the air outlet 1112.

[0043] In some embodiments, Figure 2 As shown, the shell 10 also includes a first abutment portion 17 extending toward the protrusion 1211, and the first abutment portion 17 abuts against the end surface of the protrusion 1211, thereby keeping the liquid storage component 12 fixed. When the electronic atomization device 100 is inverted, the first abutment portion 17 can support the liquid storage component 12.

[0044] Further in some embodiments, Figure 2 and Figure 3As shown, the protrusion 1211 includes a first protrusion 1211a and a second protrusion 1211b, and there are two corresponding first abutting portions 17, one of which abuts against the first protrusion 1211a, and the other first abutting portion 17 abuts against the second protrusion 1211b, and the first protrusion 1211a and the second protrusion 1211b are symmetrically arranged about the axial center line of the tubular body 111, so that both sides of the liquid storage component 12 are subjected to the force applied by the first abutting portion 17, thereby making the liquid storage component 12 balanced and firmly fixed in the electronic atomization device 100.

[0045] In some embodiments, Figure 3 As shown, the first end surface 121 includes a portion of the arc surface 1212, and the arc surface 1212 is arranged between the protrusion 1211 and the first through hole 123, so that when the electronic atomization device 100 is inverted, the liquid matrix flows out of the first through hole 123, and the arc surface 1212 can guide the outflowing liquid matrix to the protrusion 1211. Alternatively, in some embodiments, the liquid matrix flowing out of the first through hole 123 can also be guided to the protrusion 1211 by means of an inclined surface.

[0046] In some embodiments, Figure 2 and Figure 6 As shown, the housing 10 further includes a second abutting portion 18 extending toward the liquid storage member 12 and abutting against the liquid storage member 12. A liquid guiding groove 181 extending to the first end surface 121 of the liquid storage member 12 is formed on the surface of the second abutting portion 18. The liquid guiding groove 181 is disposed adjacent to the air inlet 111. The condensed liquid formed by the mixture of the high-temperature aerosol generated by the atomizing assembly 13 and the external cold air will adhere to the inner wall of the tubular body 111. Since the liquid guiding groove 181 is disposed adjacent to the air inlet 111, the condensed liquid will be absorbed by the liquid storage member 12 along the liquid guiding groove 181 under the capillary force of the liquid storage member 12, thereby slowing down the condensed liquid in the tubular body 111 from being inhaled by the user when the user inhales.

[0047] Further in some embodiments, Figure 7 As shown, the end face of the air inlet end of the tubular body 111 is formed with a notch 1113 arranged opposite to the liquid guide groove 181, and the condensate in the tubular body 111 can flow into the liquid guide groove 181 through the notch 1113, that is, the notch 1113 can guide the condensate into the liquid guide groove 181, which is beneficial to the smooth flow of the condensate into the liquid guide groove 181.

[0048] And, in some embodiments, as Figure 7As shown, the tubular body 111 includes a side wall 1114 extending between the air inlet end and the air outlet end, and the side wall 1114 and the end surface of the air inlet end are connected with an inclined surface 1115, and the inclined surface 1115 extends to the notch 1113. Therefore, when the electronic atomization device 100 is inverted, the liquid matrix stored in the receiving chamber 12 will flow back along the tubular body 111, and the inclined surface 1115 can guide the refluxed liquid matrix to the notch 1113, and further guide it to the liquid guide groove 181 through the notch 1113, and finally flow back to the liquid storage member 12 through the liquid guide groove 181.

[0049] In some embodiments, Figure 2 and Figure 6 As shown, the first abutment portion 17, the second abutment portion 18 and the first end surface 121 of the liquid storage member 12 define a chamber 124, and the air inlet 1111 of the tubular body 111 is located in the chamber 124, that is, the aerosol is first transmitted to the chamber 124 through the air duct 14, and then enters the tubular body 111 through the air inlet 111. The chamber 124 reduces the contact space of the aerosol, thereby reducing the generation of condensate.

[0050] Further in some embodiments, Figure 8 As shown, in order to avoid a pressure difference between the inside of the chamber 124 and the outside of the chamber 124, which would cause the liquid matrix to leak out of the liquid storage member 12 due to the pressure difference, the first abutting portion 17 and the second abutting portion 18 define a ventilation opening 171. By providing the ventilation opening 171, the air pressure between the inside of the chamber 123 and the outside of the chamber 124 can be balanced.

[0051] Alternatively, in some embodiments, the vent opening 171 is disposed on the first abutting portion 17, that is, the vent opening 171 is defined by the first abutting portion 17. Alternatively, in some embodiments, the vent opening 171 is disposed on the first abutting portion 18, and further defined by the second abutting portion 18.

[0052] It should be noted that the atomizer assembly 13 of the present application does not necessarily need to be arranged in the liquid storage component 12. In some embodiments, the atomizer assembly 13 can also be arranged outside the liquid storage component 12. It is only necessary to enable the liquid matrix in the liquid storage component 12 to be transferred to the atomizer assembly 13 to be atomized to produce an aerosol.

[0053] And, it should be noted that the electronic atomization device 100 may not include the battery core 15, and the electronic atomization device 100 may be powered by an external power supply assembly. Specifically, a conductive contact (not shown) may be provided on the electronic atomization device 100, and a power supply terminal (not shown) may be provided on the power supply assembly. The electronic atomization device 100 is connected to the external power supply assembly by a detachable connection method, such as a magnetic connection, a snap connection, etc. When the electronic atomization device 100 is connected to the external power supply assembly, the power supply terminal of the power supply assembly can be in contact with the conductive contact to achieve electrical connection, so that the power supply assembly can provide electrical energy to the electronic atomization device 100.

[0054] Furthermore, it should be noted that, in the electronic atomization device 100 in the above embodiment, the nozzle 11 and the housing 10 may be integrally formed, or the nozzle 11 may be mounted on the housing 10 .

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Under the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above, which are not provided in detail for the sake of simplicity. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
