The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, an electronic atomizer 100 according to an embodiment of the present disclosure is substantially cylindrical, and includes a housing 11, a suction nozzle 12, a lamp housing 13, a liquid container 14, a sealing member 15, a base 16, an atomizing core 17, a liquid blocking member 18, a liquid blocking member 19, a battery 20, a sealing member 21, and a control unit 22.

As shown in fig. 4, the housing 11 is tubular with two open ends, and has a proximal end 111 and a distal end 112.

As shown in fig. 5, the nozzle 12 has a mouth end 121 and a distal end 122, an airflow passage 123 extending from the mouth end 121 to the distal end 122, a connecting portion 124 extending from a wall of the airflow passage 123 toward the distal end 122, an abutment portion 125 radially spaced from the distal end 122, a receiving portion 1251 formed between the abutment portion 125 and the distal end 122, and a step 126. In other examples, it is also possible that the connecting portion 124 is a cantilever extending from the distal end 122 in a direction away from the distal end 122. And is not particularly limited herein.

As shown in fig. 6 to 7, the liquid container 14 is substantially cylindrical, and has an open end and a closed end opposite to the open end. After the closed end 142 of the liquid container 14 is pressed from the proximal end 111 of the housing 11, the open end 141 of the liquid container 14 is positioned at the proximal end 111 of the housing 11 such that a major portion of the liquid container 14 is received in the inner space of the housing 11.

Specifically, the liquid container 14 has a plurality of ribs 143 protruding outward from the electronic atomizer 100 on the circumferential surface or the outer surface thereof, and after the closed end 142 of the liquid container 14 is pressed from the proximal end 111 of the housing 11, the ribs 143 abut against the inner surface of the housing 11, thereby preventing the liquid container 14 from moving in the radial direction. The number of the ribs 143 is not limited herein, and in this example, 8 ribs 143 are provided at equal intervals in the circumferential direction of the liquid container 14. The open end 141 of the liquid container 14 extends in a direction out of the electronic atomization device 100 to form a flange 144. When the open end 141 of the liquid container 14 is positioned at the proximal end 111 of the housing 11, the flange 144 abuts on the end face of the proximal end 111 of the housing 11, thereby preventing the liquid container 14 from moving toward the distal end 112 of the housing 11.

The inner space of the liquid container 14 is roughly divided into a storage space 145, a receiving space 146, and a collecting space 147, and a step 148 is provided between the bottom wall 1451 of the storage space 145 and the receiving space 146. The storage space 145 is for storing liquid. An airflow hole 1471 is formed in a side wall of the liquid container 14, and the airflow hole 1471 is higher than the end surface of the closed end 142 of the liquid container 14, may be formed in a side wall of a portion of the liquid container 14 defined as the collecting space 147, may be formed in a side wall of a portion of the liquid container 14 defined as the accommodating space 146, or may span a plurality of spaces; in this example, the position of the airflow hole 1471 is provided on the side wall of the part of the liquid container 14 defined as the collection space 147, next to the housing space 146. The number of the air flow holes 1471 is not limited herein, and in this example, 4 air flow holes 1471 are provided at equal intervals along the circumferential surface of the collection space 147.

As shown in fig. 9, the base 16 has a generally tubular shape, the base 16 has a proximal end 161, a distal end 162, and a flange 163 extending outward from the electronic atomizer device 100, and after the closed end 142 of the liquid container 14 is pressed from the proximal end 111 of the housing 11, the distal end 162 of the base 16 can be directly riveted or fitted into the accommodating space 146 of the liquid container 14, so as to position the base 16 in the liquid container 14. At this time, the flange 163 abuts on the step 148, and the surface of the flange 163 is kept flush with the surface of the bottom wall 1451 of the storage space 145. A portion of the base 16 between the flange 163 and the distal end 162 having a cross-sectional area or diameter slightly larger than a corresponding cross-sectional area or diameter of the receiving space 146; thus, after riveting or assembling, interference is formed between the base 16 and the receiving space 146, thereby ensuring that a seal is maintained between the outer surface of one end of the base 16 and a portion of the inner surface of the liquid container 14, and maximally preventing liquid from flowing out from the gap therebetween.

Referring to fig. 2-3 and 9-10, the base 16 includes an air guide section (between the receiving section and the proximal end 161) and a receiving section for receiving the atomizing core 17, the receiving section having an inner diameter greater than that of the air guide section. The atomizing core 17 includes a porous base 171, a heat generating element 172, an electric wire 173, and an electric wire 174. The heating element 172 is disposed on the inner surface of the porous substrate 171 or embedded in the porous substrate 171. The

electric wires

173 and 174 are connected to the heating element 172, respectively, and are coupled to the battery 20. The atomizing core 17 is disposed in the accommodating section of the base 16, the pipe wall of the base 16 has a plurality of liquid inlets 164, the liquid inlets 164 are located above the flange 163, and the atomizing core 17 is in fluid communication with the storage space 145 through the liquid inlets 164. It should be noted that the atomizing core 17 is not limited to the case shown in fig. 10; for example, it is also possible that the usual heating element is wound around the transverse liquid transfer unit.

Further, in order to prevent the liquid from flowing downward from the atomizing core 17, a tubular liquid blocking member 18 is further provided below the atomizing core 17, and the liquid blocking member 18 is provided in the base 16 together with the atomizing core 17. The material of the liquid-blocking member 18 is not limited herein, and may be a common material, such as oil-absorbing cotton.

After the distal end 162 of the base 16 is riveted to the receiving space 146 of the liquid container 14, the liquid can be injected into the storage space 145 from the open end 141 of the liquid container 14. After the liquid is injected, the storage space 145 is sealed by the sealing member 15 and the suction nozzle 12 is attached to the base 16. In this example, the longitudinal length of the base 16 is sufficiently long to allow, on the one hand, the proximal end 161 of the base 16 to be connected to the mouthpiece 12 after the distal end 162 of the base 16 is riveted to the receiving space 146 of the fluid container 14; on the other hand, as can be seen in the figures, the wall of the base 16 above the atomizing core 17 forms an airflow channel, thus eliminating the need for a separate airflow tube between the proximal end 161 of the base 16 and the mouthpiece 12. It is also readily envisioned that a separate air flow tube could be provided between the proximal end 161 of the base 16 and the suction nozzle 12.

Further, in order to prevent the liquid from flowing down or leaking from the gap between the liquid container 14 and the housing 11, a tubular liquid blocking member 19 is further provided at the closed end 142 of the liquid container 14. The material of the liquid blocking member 19 can be referred to as the liquid blocking member 18.

As shown in fig. 8, the sealing member 15 is disposed between the storage space 145 and the suction nozzle 12. The seal 15 includes an inner tube 151, an outer tube 152, a receiving portion 153 formed between the inner tube 151 and the outer tube 152, an extending portion 1521 extending from an end surface of the outer tube 152 in a direction toward the suction nozzle 12, and a protruding portion 1522 extending from a circumferential surface of the outer tube 152 in a direction toward the outside of the electronic atomizing device 100. The material of the sealing member 15 may be a common material, such as silicone.

When the storage space 145 is sealed by the seal 15, the inner tube 151 is fitted to the base 16, and the protrusion 1522 abuts against the inner surface of the liquid container 14, thereby providing a good sealing effect. The connecting portion 124 of the suction nozzle 12 cooperates with the position-limiting portion 165 of the base 16 to connect the suction nozzle 12 to the base 16, and the position-limiting portion 165 is disposed adjacent to the proximal end 161 and protrudes from the circumferential surface of the base 16 toward the outside of the electronic atomization device 100; the position-limiting portion 165 is used for limiting the position of the connecting portion 124 so as to limit the upward movement, i.e., the separation from the proximal end 161 of the base 16, of the connecting portion 124 of the suction nozzle 12, thereby realizing the child-lock function. The number of the connection portions 124 is not limited herein.

The distal end 122 of the nozzle 12 is received in the receiving portion 153 of the seal 15; the extension portion 1521 of the seal 15 is housed in the housing portion 1251 of the suction nozzle 12; the abutting portion 125 of the suction nozzle 12 abuts against the end surface of the outer tube 152 of the seal 15; the step 126 of the suction nozzle 12 abuts the flange 144 of the fluid container 14, which further positions the open end 141 of the fluid container 14 at the proximal end 111 of the housing 11.

Further, below the stopper 165, the base 16 further has an airflow hole 166, and the airflow hole 166 is provided at a position satisfying the following condition: when the suction nozzle 12 is attached to the base 16, the airflow aperture 166 is positioned above the seal 15. Thus, when the air flow flows from the base 16 to the suction nozzle 12, the air flow can flow from the air flow hole 166 of the base 16 to the gap between the inner tube 151 of the sealing member 15 and the connecting portion 124 of the suction nozzle 12, and further to the nozzle end 121. The pressure of the sealing member 15 against the storage space 145 can be reduced by the air flow hole 166, preventing liquid leakage.

As shown in fig. 11, the proximal end 131 of the globe 13 is inserted from the distal end 112 of the housing 11 and housed in the housing 11, and the distal end 132 of the globe 13 is held or abutted on the end face of the distal end 112 of the housing 11. An air inlet hole 133 is provided on the distal end 132 of the lamp housing 13.

As shown in fig. 12 to 13, the sealing member 21 has a proximal end 211, a distal end 212, a receiving portion 213, an airflow hole 214 extending from the proximal end 211 to the distal end 212, and a projection portion 215 projecting from the circumferential surface of the sealing member 21 in a direction out of the electronic atomizer 100. The material of the seal 21 can be as shown with reference to the seal 15.

A seal 21 is disposed within the housing 11 between the battery 20 and the lamp housing 13. The projection 215 of the seal 21 abuts against the inner wall or surface of the housing 11, thereby providing a good sealing effect. The control unit 22 is at least partially housed in the housing 213 of the seal 21, and in this example, the control unit 22 includes an airflow sensor and a control chip, and is integrally formed by the airflow sensor and the control chip. The control chip adopts ASIC design, can avoid the phenomenon of crashing of MCU scheme.

Fig. 3 shows the airflow path of the electronic atomization device 10. Specifically, when a user inhales aerosol, an air flow flows in from the air inlet hole 133 of the lamp shade 13, and after the control unit 22 senses the inhaled air flow, the control heating element 172 starts heating to heat the liquid transferred by the porous substrate 171 and generate inhabitable aerosol; subsequently, the air flow flows into the battery 20 from the air flow hole 214 of the sealing member 21, passes through the gap between the battery 20 and the housing 11, flows into the air flow hole 1471 on the collecting space 147, and flows into the atomizing core 17 through the liquid blocking member 18; the aerosol generated by the heating element 172 is then heated and mixed with the air flow, and flows through the (air guide) wall of the base 16 into the mouthpiece 12 for inhalation by the user.

Wherein the condensed liquid generated by the atomizing core 17 can be blocked by the liquid blocking member 18, and further, the condensed liquid which is not blocked by the liquid blocking member 18 can be collected in the collecting space 147, preventing the condensed liquid from flowing into the battery 20.

It should be noted that, in other examples, it is also possible that there is no collection space 147, and the position of the airflow hole 1471 may be provided on the side wall of the portion of the liquid container 14 defined as the housing space 146; alternatively, both ends of the liquid container 14 are open, and the air flow holes 1471 are not required.
