[0034] Please refer to Figures 1 to 6 The electronic atomizer 1 of this utility model embodiment includes a main housing 10, an atomizing device 12 and a battery 14 disposed inside the main housing 10, a circuit board 102 disposed between the atomizing device 12 and the battery 14, and a bracket 105 disposed between the circuit board 102 and the atomizing device 12; a gap 106 is left between the battery 14 and the main housing 10, a bottom cover assembly 103 is provided at one end of the main housing 10, an air inlet 107 is provided on the bottom cover assembly 103 corresponding to the gap 106, an air inlet channel 1051 is provided on the bracket 105 corresponding to the gap 106, and a first passage is opened on the circuit board 102 corresponding to the air inlet channel 1051. The first through hole 1023 and the air intake channel 1051 pass through the first through hole 1023. An air intake space 1054 is defined within the air intake channel 1051. The air intake port 107, the gap 106 and the air intake space 1054 are connected in sequence. The gap 106 is set to isolate the battery 14 from the path through which external air enters the electronic atomizer 1, so as to avoid the influence of condensation on the battery 14 and other electrical components, and protect the battery 14. At the same time, the air intake channel 1051 passes through the first through hole 1023 on the circuit board 102, which can also avoid the influence of condensation on the circuit board 102, protect the circuit board 102 and extend its service life.

[0035] Further, please refer to Figure 2 and Figure 5 The main housing 10 also includes a mouthpiece 100, which is located on the side of the atomizing device 12 away from the battery 14. An airflow space 1052 is formed between the bracket 105 and the atomizing device 12. The atomizing device 12 includes a refilling component 120 and an atomizing component 121 arranged at intervals. The atomizing component 121 and the mouthpiece 100 together define an atomization channel 1210. The air inlet 107, the gap 106, the air inlet channel 1051, the airflow space 1052 and the atomization channel 1210 are connected in sequence. The atomizing component 121 has a separate atomization channel 1210 to ensure that outside air only flows into the atomizing component 121 and does not enter the refilling component 120, thus preventing the e-liquid in the refilling component 120 from flowing back.

[0036] Furthermore, please combine Figure 4 and Figure 5A conductive ring 140 is provided at one end of the battery 14 near the circuit board 102, and a spring pin 1022 is provided on the circuit board 102 corresponding to the conductive ring 140; the spring pin 1022 is used to electrically connect to the battery 14, eliminating the need for complicated wire connections and making installation simpler.

[0037] Furthermore, the atomizing assembly 121 includes an atomizing core 1211 and a heating wire 1212 disposed within the atomizing core 1211. The atomizing core 1211 is disposed within the atomizing channel 1210. The bracket 105 has a wire hole 1053 corresponding to the heating wire 1212. The heating wire 1212 passes through the wire hole 1053 and is electrically connected to the circuit board 102. The heating wire 1212 passes directly through the bracket 105, avoiding excessive winding, making the internal structure simpler and simplifying the installation steps.

[0038] Furthermore, a first absorbent cotton 1050 is provided in the airflow space 1052; the first absorbent cotton 1050 can absorb the condensation water generated by the cold air, prevent it from entering the atomization channel 1210, ensure that the e-liquid is fully burned, and improve the user's vaping experience.

[0039] Furthermore, the circuit board 102 is electrically connected to a control button 1021; the control button 1021 is used to adjust the heating power of the atomizing component 121, thereby changing the combustion effect of the e-liquid and enriching the user experience.

[0040] Specifically, a microphone 1020 is electrically connected to the circuit board 102. The microphone 1020 is an airflow sensor used to sense changes in airflow within the electronic atomizer 1 in order to adjust the combustion command for the e-liquid.

[0041] Specifically, a lower oil seal 104 is provided between the atomizing device 12 and the circuit board 102. The lower oil seal 104 is provided with an oil plug 1040 corresponding to the oil supply pipe 125. The oil plug 1040 blocks the lower end of the oil supply pipe 125 to prevent oil from leaking into the circuit board 102 and causing pollution.

[0042] Furthermore, please combine Figure 6 The main housing 10 has a suction nozzle 100 and a bottom cover assembly 103 on opposite sides. The bottom cover assembly 103 includes a connector 1030 fixedly connected to the main housing 10 and an end cover 1031 detachably connected to the connector 1030. The end cover 1031 and the connector 1030 are respectively provided with a snap-fit ​​block 1032 and a snap-fit ​​slot 1033. The end cover 1031 abuts against the battery 14. The detachable end cover 1031 makes it convenient for users to replace the battery 14 or charge the battery 14. At the same time, the end cover 1031 abuts against the battery 14 so that the battery 14 is always electrically connected to the circuit board 102, ensuring the stability of the connection.

[0043] Understandably, the connector 1030 may be integrally formed with the main housing 10.

[0044] Further, please refer to Figure 4 and Figure 5 The electronic atomizer 1 also includes an oil cup 11. The main housing 10 has a mounting slot 101 corresponding to the oil replenishment component 120. The oil cup 11 is detachably installed in the mounting slot 101. The oil cup 11 is used to continuously supply e-liquid to the atomizing device 12. The detachable oil cup 11 is easy to replace, which improves the durability of the electronic atomizer 1.

[0045] Specifically, the oil cup 11 includes a cup shell 111 with a cup opening 110 at one end and a plunger assembly 112 disposed at the cup opening 110. When not installed, the plunger assembly 112 seals the e-liquid in the oil cup 11, preventing leakage. During installation, the oil cup 11 is simply inserted into the mounting slot 101, eliminating the need for manual opening and making operation convenient. Simultaneously, the cup opening 110 of the oil cup 11 is in an inverted state during installation, allowing the e-liquid in the oil cup 11 to continuously and stably flow into the oil replenishment assembly 120, ensuring continuous combustion of the e-liquid.

[0046] Specifically, the inner wall of the mounting groove 101 is provided with a limiting protrusion 1011, and the cup shell 111 is provided with a limiting groove 113 corresponding to the limiting protrusion 1011; the cooperation between the limiting groove 113 and the limiting protrusion 1011 can fix the oil cup 11 in the mounting groove 101, so that the oil cup 11 will not easily fall off, thus improving the structural stability; the end of the cup shell 111 away from the cup opening 110 is provided with a handle 1110; the handle 1110 makes it convenient for users to take out and replace the oil cup 11, which is convenient for daily use.

[0047] Furthermore, the bottom wall of the mounting groove 101 is also provided with a second through hole 1010. The oil replenishment assembly 120 includes an oil replenishment tube 125 and an oil control cotton 126 disposed inside the oil replenishment tube 125. Part of the oil replenishment tube 125 extends into the mounting groove 101 through the second through hole 1010. The oil control cotton 126 is disposed inside the oil replenishment tube 125 to facilitate the e-liquid flowing from the oil cup 11 into the oil replenishment tube 125 more evenly. When the oil cup 11 is connected to the oil replenishment assembly 120, the oil replenishment tube 125 will squeeze the main housing 1 when it extends into the oil filling channel. The air inside the tube causes the e-liquid to enter the refill tube 125 very quickly, which may cause it to rush out of the tube 125, resulting in splattering. The e-liquid control cotton 126 slowly absorbs the e-liquid, thus slowing down the flow of the e-liquid and preventing splattering, resulting in more even refilling. At the same time, there is a pressure relationship between the inside and outside of the refill tube 125, which is determined by the e-liquid density of the e-liquid storage cotton 122 and the e-liquid control cotton 126. When the e-liquid in the storage cotton 122 is insufficient, the e-liquid in the e-liquid control cotton 126 is automatically replenished according to the pressure relationship.

[0048] For specific details, please refer to... Figure 7The portion of the oil replenishment pipe 125 that extends into the mounting groove 101 is defined as the first part 1250, and the portion set inside the main housing 10 is defined as the second part 1251. The side wall of the second part 1251 is provided with at least two oil seepage holes 1252 at equal intervals around the second part 1251. Providing oil seepage holes 1252 at equal intervals on the side wall can further improve the oil replenishment speed while ensuring uniform oil replenishment, and also ensures that the oil is more evenly distributed in the oil storage cotton 122.

[0049] Understandably, when the oil cup 11 is inserted into the mounting slot 101, the first part 1250 can push the plunger assembly 112 to open the cup opening 110, allowing the e-liquid to flow into the oil replenishment assembly 120.

[0050] Specifically, the first part 1250 has a notch 1256 at the end away from the second through hole 1010; the notch 1256 is set to allow more of the oil control cotton 126 to come into contact with the e-liquid and increase the oil seepage rate.

[0051] For details, please refer to Figure 5 and Figure 7 The main housing 10 also includes an inner housing 13. An oil-storing cotton 122 is disposed inside the inner housing 13. A sealing element 123 is fixed in the inner housing 13. A pressure-stabilizing space 124 is defined between the sealing element 123 and the oil-storing cotton 122. A vent hole 1255 is provided on the side wall of the oil supply pipe 125 corresponding to the pressure-stabilizing space 124. It can be understood that the vent hole 1255 is provided to adjust the pressure inside and outside the oil supply pipe 125 so that the e-liquid can flow smoothly into the oil-controlling cotton 126.

[0052] Specifically, the two opposite sides of the oil seepage hole 1252 are long sides 1253, and the other two opposite sides are short sides 1254. The length of the long side 1253 is greater than the length of the short side 1254. The axis of the long side 1253 and the oil supply pipe 125 (e.g.) Figure 7 The center line L) is parallel; this setting is to ensure that the e-liquid seeping out of the oil control cotton 126 can follow the direction of e-liquid falling, and will not cause uneven seepage of oil on both sides of the oil replenishment tube 125.

[0053] Furthermore, a second absorbent cotton 1213 is provided inside the atomizing channel 1210, which abuts against the inner wall of the atomizing channel 1210. Unburned e-liquid in the atomizing core 1211 will flow down along the inner wall of the atomizing channel 1210, and the second absorbent cotton 1213 can completely absorb it, preventing the e-liquid from contaminating other components and improving the service life of the electronic atomizer 1.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
