The whole atomizer 300 is detachably connected to the housing 100 at two positions, namely, the normal position 11 and the inverted position 12, and referring to fig. 3 and 5, when the atomizer 300 is located at the normal position 11, the suction nozzle end face 324 faces upward and is arranged opposite to the battery assembly 200, the connection end face 364 faces downward and is arranged opposite to the battery assembly 200, the battery assembly 200 is inserted into the insertion hole 362, the electrode posts 230 on the battery assembly 200 are electrically connected with the electrode contacts 365 on the base assembly 360 in an abutting manner, at this time, the atomizer 300 is in a working or standby state, and a user can suck smoke generated by the atomizer 300. When the battery pack 200 is fitted into the insertion hole 362, the stopper surface 221 of the boss portion 220 abuts against the stopper 366 located in the insertion hole 362, and the flange 363 is compressed to be tightened against the side peripheral surface 223 of the boss portion 220 (the side peripheral surface 223 is connected to the stopper surface 221), in short, the flange 363 tightens against the boss portion 220, which arrangement can serve three functions: firstly, the battery assembly 200 can be positioned by abutting the limiting surface 221 and the limiting block 366, so that the electrode column 230 and the electrode contact 365 are just in an abutting state, and the damage to the electrode column 230 and the electrode contact 365 caused by large abutting pressure generated by inaccurate positioning is prevented; meanwhile, the silicone seat 361 has certain flexibility, and does not wear the electrode column 230 or cause elastic fatigue of the electrode column 230. Secondly, the connection end surface 364 of the silicone seat 361 and the mounting surface 212 of the main body portion 210 are spaced from each other without contacting each other by the limiting action of the limiting stopper 366. Thirdly, when the limiting surface 221 abuts against the limiting block 366, the flange 363 contracts due to the pressing of the boss part 220, so that the flange 363 grips the boss part 220 to seal the insertion hole 362, that is, the boss part 220 seals a part of the insertion hole 362 to form a circulation chamber 362a, the circulation chamber 362a simultaneously communicates with the sensing air passage 222 and the air inlet hole 325, and at this time, the circulation chamber 362a also communicates with all the smoke passages 302. Therefore, when the user sucks, the air flowing in from the air inlet 325 will carry the air in the circulation chamber 362a and the sensing air channel 222 to be sucked by the user through the smoke channel 302, so that a certain negative pressure is provided in the circulation chamber 362a, and after the air pressure sensor 215 accurately senses the negative pressure, the battery assembly 200 can be controlled to supply power to all the atomizing assemblies 350, so that all the atomizing assemblies 350 atomize the liquid at the same time.

Under the condition that the atomizer 300 is located at the right position 11, the convex column 110 on the housing 100 is just abutted to the stop end 211b of the sliding groove 211, which is close to the atomizer 300, so that one end of the battery assembly 200, which is far away from the atomizer 300, is exposed out of the accommodating cavity 101, at this time, a user can apply upward pushing force to the part of the battery assembly 200, which is exposed out of the accommodating cavity 101, so as to push the battery assembly 200 to slide upward, because the limiting surface 221 of the boss part 220 applies upward pushing force to the limiting block 366, under the action of the pushing force, the elastic clamping column 322 on the atomizer 300 is separated from being matched with the clamping hole 120 of the housing 100, so that the connection relationship between the atomizer 300 and the housing 100 is released, and the atomizer 300 can be conveniently taken out of the accommodating cavity 101. In the process that the battery assembly 200 slides upwards, the battery assembly 200 pushes the atomizer 300 to also slide upwards, when the convex column 110 on the housing 100 is just abutted against the limit end 211a of the sliding groove 211 far away from the atomizer 300, the upward sliding stroke of the battery assembly 200 reaches the limit, the battery assembly 200 stops sliding, and at this time, the battery assembly 200 pushes most of the atomizer 300 to be exposed out of the accommodating cavity 101, so that a user can directly hold the exposed part of the atomizer 300 to take away the atomizer 300. Of course, for convenience of suction, when the atomizer 300 is in the upright position 11, the nozzle end surface 324 of the mounting case 320 may be located outside the accommodation chamber 101, and the nozzle end surface 324 may be spaced apart from the end surface of the housing 100. In short, a portion of the atomizer 300 is exposed out of the accommodating chamber 101.

Referring to fig. 4, when the atomizer 300 is in the resting state of being stopped, the atomizer 300 may be connected to the housing 100 as well, at this time, the atomizer 300 is in the inverted position 12, at the inverted position 12, the suction nozzle end surface 324 faces downward and is disposed facing the battery assembly 200, the connection end surface 364 faces upward and is disposed opposite to the battery assembly 200, and the connection end surface 364 is flush with the end surface of the housing 100, or the connection end surface 364 is spaced from the end surface of the housing 100 and is located in the accommodating cavity 101, so that the whole atomizer 300 does not have a portion exposed out of the accommodating cavity 101, and the occupied space of the whole electronic atomization device 10 during carrying and storage is reduced as much as possible. In colloquial, when the nebulizer 300 is connected to the housing 100 in the upright state (operating state), the nebulizer 300 is in the upright position 11; when the nebulizer 300 is connected to the housing 100 in an inverted state (resting state), the nebulizer 300 is in the inverted position 12.

When the atomizer 300 is at the inverted position 12, the suction nozzle end face 324 is located in the accommodating cavity 101, obviously, the opening 323b of the suction nozzle hole 323 on the suction nozzle end face 324 is also located in the accommodating cavity, that is, the housing 100 forms a protection function for the suction nozzle hole 323, which effectively prevents foreign dust or liquid drops and other impurities from invading into the atomizer 300 from the suction nozzle hole 323 to form pollution, and when the atomizer 300 is used again, the user can be prevented from inhaling the above impurities from the suction nozzle hole 323 to form harm to human health, thereby improving the sanitary safety of the whole electronic atomization device 10 in the using process. Meanwhile, the boss part 220 of the battery pack 200 is received in the suction nozzle hole 323, and the suction nozzle end surface 324 of the mounting case 320 is in contact with the mounting surface 212 of the main body part 210, so as to limit the battery pack 200, so that the electrode column 230 is not in contact with the bottom wall 323a of the suction nozzle hole 323, that is, the end of the electrode column 230 keeps a set distance from the bottom wall 323a of the suction nozzle hole 323, and the electrode column 230 is prevented from being damaged due to collision between the electrode column 230 and the bottom wall 323a of the suction nozzle hole 323. Further, the contact between the nozzle end face 324 and the mounting surface 212 can provide a sealing function for the opening 323b of the nozzle hole 323, so that the battery module 200 can further protect the nozzle hole 323, and foreign matter such as dust and liquid drops can be more prevented from entering from the nozzle hole 323. In other embodiments, for example, the opening 323b of the nozzle hole 323 on the nozzle end surface 324 may be located outside the receiving cavity 101, but the main body portion 210 or the boss portion 220 of the battery assembly 200 may block the nozzle hole 323, and also prevent the impurities from entering into the nozzle hole 323. For another example, when the suction nozzle end face 324 is positioned in the accommodation chamber 101, the main body portion 210 or the boss portion 220 of the battery pack 200 blocks the suction nozzle hole 323, and the suction nozzle hole 323 is doubly protected by both the battery pack 200 and the case 100, so that the foreign matter is more difficult to enter from the suction nozzle hole 323.

When the atomizer 300 is in the inverted position 12, the protruding column 110 on the housing 100 is just abutted to the stopping end 211b of the sliding groove 211, which is close to the atomizer 300, as in the case when the atomizer 300 is in the upright position 11, so that the end of the battery pack 200, which is far away from the atomizer 300, is exposed to the accommodating cavity 101. When a user applies upward pushing force to the part of the battery assembly 200 exposed out of the accommodating cavity 101, the mounting surface 212 of the main body portion 210 applies upward pushing force to the suction nozzle end surface 324 of the mounting shell 320, so that the elastic clamping columns 322 are disengaged from the clamping holes 120, the connection relationship between the atomizer 300 and the housing 100 is released, when the upward sliding stroke of the battery assembly 200 reaches the limit, the battery assembly 200 stops sliding, the battery assembly 200 pushes most of the atomizer 300 to be exposed out of the accommodating cavity 101, and the user can conveniently and directly hold the exposed part of the atomizer 300 to take away the same.

During use of the electronic atomizer device 10, the atomizer 300 is placed in the right position 11 when suction is required. After the suction is finished and the suction is not performed for a long time, the battery assembly 200 may be pushed upward, so that the elastic locking pillar 322 is separated from the locking hole 120 to release the connection relationship between the atomizer 300 and the housing 100, and the atomizer 300 in the normal position 11 is pushed out of the accommodating cavity 101 by the battery assembly 200. Next, the user takes out the nebulizer 300 from the accommodation chamber 101 and turns it from the upright state to the inverted state, and then reconnects the nebulizer 300 in the inverted state to the housing 100, i.e., causes the elastic latching columns 322 to be re-engaged with the latching holes 120, thereby preventing foreign substances from entering the nozzle holes 323. When the suction is needed again, the battery assembly 200 is also pushed upwards, so that the elastic clamping column 322 is separated from the clamping hole 120 to release the connection relationship between the atomizer 300 and the housing 100, and the atomizer 300 at the inverted position 12 is pushed out of the accommodating cavity 101 by the battery assembly 200. Then, the user takes out the nebulizer 300 from the accommodation chamber 101 and turns it from the inverted state to the upright state, and then, connects the nebulizer 300 in the upright state with the housing again, and can perform suction again.

Therefore, the battery assembly 200 is slidably connected to the housing 100, and the atomizer 300 can be quickly mounted and dismounted only by pushing the battery assembly 200 to slide in the accommodating cavity 101 without other complicated parts and structural designs, so that the structure of the whole electronic atomization device 10 is simplified, and the electronic atomization device 10 is more convenient to use.

When the liquid storage cylinder 340 forms two independent liquid storage cavities 341 by arranging the liquid separation plate 342, each liquid storage cavity 341 corresponds to one atomizing assembly 350. When the user sucks, the air pressure sensor 215 can sense the existence of negative pressure through sensing the air passage 222 and the circulating cavity 362a, so that the battery assembly 200 can supply power to the two atomizing assemblies 350 simultaneously, the two atomizing assemblies 350 atomize liquid simultaneously to form smoke, and compared with one atomizing assembly 350, the amount of smoke generated by the two atomizing assemblies 350 working simultaneously is increased, so that the concentration of the smoke is increased. Meanwhile, the two liquid storage cavities 341 can contain liquids with different tastes, and the smoke with different tastes is mixed in the suction nozzle hole 323 to be sucked by a user, so that the tastes of the electronic atomization device 10 can be enriched, and the taste diversity is improved. In other embodiments, the number of both reservoirs 341 and atomizing assembly 350 may be one or greater than two. When less smoke concentration is required, or only one flavor is required, one atomizer 350 can be turned on alone.

When the number of the atomizing assemblies 350 is two, the number of the first electrode 231 as the positive electrode is one, the first electrode 231 is disposed centrally on the boss portion 220, and the first electrode 231 as the positive electrode is electrically connected to all the atomizing assemblies 350 at the same time, that is, all the atomizing assemblies 350 share one first electrode 231. The number of the second electrodes 232 as the negative electrodes is two, the two second electrodes 232 are symmetrically distributed on two sides of the first electrode 231, and the two second electrodes 232 are electrically connected to different atomizing assemblies 350 respectively. The number of the sensing electrodes 233 is also two, and the two sensing electrodes 233 are positioned at the outermost edge and are also symmetrically arranged with respect to the first electrode 231. By providing the sensing electrode 233, taste information of the smoke generated by the different atomizing assemblies 350 can be recognized.

Referring to fig. 19 to 23, in some embodiments, the atomizer 300 further includes a liquid absorbing assembly 370, the liquid absorbing assembly 370 includes an ejector 371, a liquid absorbing member 372, an elastic member 373, and a closing member 375, and the liquid absorbing member 372 may be made of absorbent cotton, so that the liquid absorbing member 372 has a good liquid absorbing function. The surface of the bottom wall 323a of the ejector 371 facing the nozzle hole 323 is concavely formed with a sunken groove 371a, the liquid absorbing piece 372 is embedded in the ejector 371 by matching with the sunken groove 371a, so that the liquid absorbing piece 372 is closer to the bottom wall 323a of the nozzle hole 323 relative to the ejector 371, and meanwhile, the liquid absorbing piece 372 can also be arranged close to the side wall of the nozzle hole 323, so that the liquid absorbing piece 372 can rapidly absorb condensate on the side wall of the nozzle hole 323. The ejector 371 may further have an air outlet 371b, and the air outlet 371b communicates with the suction nozzle hole 323. The pushing member 371 is slidably disposed in the nozzle hole 323, and when the pushing member 371 slides, the liquid absorbing member 372 can slide in the nozzle hole 323 along with the pushing member 371, so that the liquid absorbing member 372 can absorb the condensate on the sidewall of the nozzle hole 323 to the maximum extent. Since the condensate is absorbed in the liquid absorbing member 372 and the condensate absorbed in the liquid absorbing member 372 cannot penetrate the pushing member 371, the user cannot suck the condensate in the nozzle hole 323 during the suction process, thereby improving the hygienic safety of the whole atomizer 300 during use.

The side wall of the nozzle hole 323 is provided with a limit protrusion 376, the limit protrusion 376 is arranged close to the nozzle end face 324, for example, the surface of the limit protrusion 376 may be flush with the nozzle end face 324, and when the pushing member 371 abuts against the limit protrusion 376 in the case that the pushing member 371 slides close to the nozzle end face 324, the pushing member 371 stops sliding, that is, the limit protrusion 376 limits the limit stroke of the pushing member 371 sliding close to the nozzle end face 324, and the whole liquid absorbing assembly 370 can also be prevented from falling out of the nozzle hole 323.

Be provided with sand grip 374 on the diapire of nozzle hole 323, elastic component 373 can be the spring, and the spring housing is established on sand grip 374, and sand grip 374 plays the guide orientation effect to the spring, and the lower extreme of spring and the diapire butt of nozzle hole 323, the upper end of spring can with push up piece 371 butt. The sealing element 375 can be a sealing ring which is sleeved on the ejector 371 and is abutted between the ejector 371 and the side wall of the suction nozzle hole 323, and the condensate on the side wall can be prevented from flowing out of the suction nozzle hole 323 through the arrangement of the sealing element 375.

With respect to the atomizer 300 including the wicking assembly 370, when the atomizer 300 is in the upright position 11, the mist generated by the atomizing assembly 350 can be drawn by the user through the nozzle hole 323 and the outlet hole 371 b. Meanwhile, due to the absorption effect of the liquid absorbing piece 371 on the condensate, the condensate in the suction nozzle hole 323 can not be sucked into the oral cavity of the user, and the safety and the sanitation of the atomizer 300 are further improved. Of course, the air outlet 371b may be eliminated on the basis of the good air permeability of the ejector 371. When the atomizer 300 is in the inverted position 12, the electrode column 230 may be received in the air outlet hole 371b of the ejector 371. Meanwhile, the limiting surface 221 of the boss portion 220 is abutted against the surface of the pushing piece 371, the pushing piece 371 moves towards the direction close to the bottom wall of the suction nozzle hole 323, the elastic piece 373 is gradually compressed, the pushing piece 371 drives the liquid absorbing piece 372 to contact the bottom wall of the suction nozzle hole 323, at the moment, the condensate on the bottom wall 323a and the side wall of the suction nozzle hole 323 is completely absorbed by the liquid absorbing piece 372, the condensate is prevented from contacting the battery pack 200 to corrode the battery pack 200, and the service life of the battery pack 200 and the service life of the electronic atomization device 10 are prolonged. When the atomizer 300 is at the inverted position 12, the stopper surface 221 of the boss portion 220 abuts against the ejector 371 so that the mounting surface 212 of the body portion 210 and the nozzle end surface 324 are not in contact with each other, but are spaced apart from each other at a predetermined distance. When the atomizer 300 needs to be ejected out of the accommodating cavity 101, the battery pack 200 can be pushed, and the limit surface 221 applies an upward acting force to the ejector 371, so that the connection between the atomizer 300 and the housing 100 is released and the atomizer 300 is ejected out of the battery pack 200.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
