Fig. 1 is a schematic overall structure diagram of an atomizer provided in an embodiment of the present application, fig. 2 is a schematic exploded structure diagram of an atomizer provided in an embodiment of the present application, and in combination with fig. 1 and fig. 2, the present application discloses an atomizer 10 including an atomizing core 12, a microphone 13, a housing 11, and a power supply assembly 16. The following discussion refers to an e-cigarette as a specific atomizer.

The atomizing core 12, the microphone 13 and the power supply assembly 16 of the atomizer 10 are respectively arranged in the housing 11, and the housing 11 is provided with an atomizer air inlet 114 for introducing external air; the atomizing core 12 is provided with an atomizing core air inlet 120, after external air enters from the atomizer air inlet 114, a part of the external air is used for sensing the microphone 13 to supply power to the atomizing core 12 through the power supply assembly 16 for starting the atomizer 10, and the other part of the external air enters the atomizing core through the atomizing core air inlet 120 and is sucked out through the atomizing core air outlet 123 after being mixed with the atomized tobacco tar in the atomizing core 12.

The atomizer 10 further comprises a microphone protection structure 14 for protecting the microphone 13 and a storage cavity 15 for storing condensed oil leaked from the atomizing core 12, wherein the microphone protection structure 14 comprises a cavity 142, an air inlet 144 and an air outlet 145; the microphone 13 is disposed in the cavity 142 of the microphone protection structure 14, the microphone 13 includes an air inlet surface 131 and a sensing surface 132, the air inlet surface 131 of the microphone 13 faces the air inlet 144 of the microphone protection structure 14, the sensing surface 132 of the microphone 13 faces the air outlet 145 of the microphone protection structure 14, a microphone starting air passage 19 is formed between the sensing surface 132 of the microphone 13 and the air outlet 145 of the microphone protection structure 14, the air inlet 144 of the microphone protection structure 14 is communicated with the atomizer air inlet 114, and after external air enters from the atomizer air inlet 114, a part of the external air enters the microphone starting air passage 19 from the air inlet surface 131 and the sensing surface 132 of the microphone 13 through the air inlet 144 of the microphone protection structure 14 to be used for sensing and starting the microphone 13.

The storage cavity 15 is arranged at the end part of the air outlet 145 of the microphone protection structure 14 far away from the atomizing core 12; the storage chamber 15 includes oppositely disposed outer and inner side walls 150 and 151; the end part of the air outlet 145 of the microphone protection structure 14 is parallel to and spaced from the outer side wall 150 of the storage cavity 15, a clearance channel 21 is formed between the end part of the air outlet 145 of the microphone protection structure 14 and the outer side wall 150 of the storage cavity 15, and the end part of the air outlet 145 of the microphone protection structure 14 protrudes from the inner side wall 151 of the storage cavity 15; the air inlet 145 of the microphone protection structure 14, the atomizing core air inlet 120, the clearance channel 21 and the storage chamber 15 are communicated with each other; wherein, the direction that the miaow head started air flue 19 with clearance channel 21's direction nonparallel, just the export that the miaow head started air flue 19 does not face atomizing core 12, the condensate oil that leaks down from atomizing core 12 is difficult to get into through the export that miaow head started air flue 19 like this, avoids the condensate oil to miaow head induction circuit's influence.

For the miaow head that will start the miaow head response and start the export of air flue 19 and set up towards atomizing core 12, and miaow head 13 does not have the scheme of sheltering from, this kind of method is because the export of miaow head start air flue 19 is towards atomizing core 12, and the volume of the condensate oil that leaks from atomizing core 12 is relatively uncontrollable, probably directly drip into the export of miaow head start air flue 19 after the condensate oil leaks from atomizing core 12, influence the response of miaow head, even the condensate oil does not directly drip into miaow head start air flue 19, but reach on the plane of miaow head start air flue 19's export, so in the use of atomizer 10, because atomizer 10 rocks, get rid of the condensate oil on the plane of miaow head start air flue 19 to the export of miaow head start air flue 19 and get into miaow head 13 department along the export, thereby influence miaow head 13's response, still can damage miaow head 13's induction circuit when the above-mentioned condition is serious, produce the influence to whole atomizer 10 atomizing.

In the application, the microphone starting air passage 19 is arranged in parallel with the outer side wall 150 of the storage cavity 15 at intervals by arranging the microphone protection structure 14 and the storage cavity 15, and a gap channel 21 is formed between the end part of the air outlet 145 of the microphone protection structure 14 and the outer side wall 150 of the storage cavity 15, so when condensed oil leaked from the atomizing core 12 drips to the microphone protection structure 14, the condensed oil can continuously flow to the storage cavity 15 along the outer wall of the microphone protection structure 14 in the direction away from the atomizing core 12 and cannot directly flow to the microphone 13 through the outlet of the microphone starting air passage 19; and miaow head start airway 19's direction with clearance passageway 21's direction nonparallel, miaow head start airway 19's export is not towards the direction of atomizing core 12 moreover, even like this atomizer 10 is under the condition of rocking, the condensate oil also is difficult to leak to miaow head start airway 19's gas outlet, even the miaow head start airway 19's gas outlet is stained with the condensate oil moreover, the condensate oil is difficult at this moment also to enter miaow head 13 along miaow head start airway 19.

The end part of the air outlet 145 of the microphone protection structure 14 protrudes out of the inner side wall 151 of the storage cavity 15, so that condensed oil in the storage cavity 15 can be blocked, the atomizer 10 is rotated clockwise, the condensed oil stored in the cavity can flow along with the condensed oil, the condensed oil is viscous, the flowing speed is slow, when the atomizer 10 is vertical, the end part of the air outlet 145 of the microphone protection structure 14 directly blocks the condensed oil leaked from the atomizing core 12, and the condensed oil is not easy to enter the microphone 13 from a port where the end surface of the end part of the air outlet 145 of the microphone protection structure 14 is communicated with the microphone starting air passage 19 after being leaked; when the atomizer 10 is in a horizontal state, the end part of the air outlet 145 of the microphone protection structure 14 is in an upward state, the condensed oil in the cavity is vertical to the end part of the air outlet 145 of the microphone protection structure 14, and the condensed oil can enter the position of the microphone 13 from the end part of the condensed oil when reaching the height of the end part of the air outlet 145 of the microphone protection structure 14; when the atomizer 10 is in an inverted state, the stored condensed oil needs to flow along the side wall of the storage cavity 15 perpendicular to the end part of the air outlet 145 of the microphone protection structure 14, and then turns after reaching a right angle formed by the end part of the microphone protection structure 14 and the side wall of the storage cavity 15, the condensed oil is likely to reach the end part of the air outlet 145 of the microphone protection structure 14, the speed is slow, and the condensed oil is not easy to bypass the end part of the air outlet 145 of the microphone protection structure 14 and enter the microphone; when the atomizer 10 is rotated, the condensed oil in the cavity flows to the inner side of the storage chamber 15 along the end of the air outlet 145 of the head protection structure 14 when the end of the air outlet 145 of the head protection structure 14 is toward the center of the earth. Therefore, even if the atomizer 10 shakes or rotates during use, the condensed oil in the storage cavity 15 can be blocked by the end of the air outlet 145 of the microphone protection structure 14, and the condensed oil flows to the outlet of the microphone starting air passage 19 along the outer side wall 150 and the inner side wall 151 of the storage cavity 15, so that the influence of the condensed oil on the microphone sensing circuit can be avoided to the greatest extent, and the atomizer 10 is guaranteed to atomize normally.

It can be seen that the microphone 13 is very important in starting the nebulization of the nebulizer 10, so that the microphone 13 needs to be protected and the sensitivity of the sensing of the microphone 13 can be ensured by different arrangements.

The atomizer air inlet 114 is arranged at the bottom of the shell 11, and the atomizing core 12 is provided with an atomizing core air inlet 120 and an atomizing core air outlet 123 for introducing external air from the atomizer air inlet 114; the end part of the air outlet 145 of the microphone protection structure 14 is suspended from the storage cavity 15; a part of air entering from the air inlet 114 of the atomizer enters the microphone starting air passage 19 through the air inlet 144 of the microphone protection structure 14 to start the microphone 13 to induce airflow negative pressure, and the power supply assembly 16 is turned on to supply power to the atomizing core 12, so that the atomizing core 12 performs atomizing work; the atomizer further comprises a main air passage 22, the main air passage 22 is communicated with the atomizer air inlet 114 and the atomizing core air inlet 120, and after entering from the atomizer air inlet, the other part of the outside air enters the atomizing core 12 from the atomizing core air inlet 120 after passing through the main air passage 22, and is mixed with the atomized tobacco tar in the atomizing core 12 for being sucked out; the casing 11 is kept away from the top of atomizer air inlet 114 is equipped with flue 17, just flue 17 with atomizing core gas outlet 123 intercommunication, in order to aspirate the gas that atomizing tobacco tar and outside air mix in the atomizing core 12, storage chamber 15 can be used to the storage from the atomizing core 12 atomizing back not by the smoke formation of suction and the condensate oil that leaks down.

Specifically, fig. 3 isbase:Sub>A schematic side view of an atomizer provided in an embodiment of the present invention, fig. 4 isbase:Sub>A schematic cross-sectional view taken alongbase:Sub>A section linebase:Sub>A-base:Sub>A' in fig. 3, fig. 5 isbase:Sub>A partially enlarged view ofbase:Sub>A region B in fig. 3, and in conjunction with fig. 3-5, the microphone actuation air duct 19 is disposed perpendicular to an outer sidewall 150 of the storage chamber 15. If the outlet of the microphone actuation air passage 19 is inclined toward the atomizing core 12, if condensed oil drops to the outlet of the microphone actuation air passage 19, the condensed oil can more easily enter the microphone 13 along the inclined air inlet channel, thereby affecting the circuit of the microphone 13; if the outlet of the microphone starting air passage 19 inclines towards the direction far away from the atomizing core 12, the turning angle between the microphone starting air passage 19 and the clearance air passage is large, the air flow is not smooth, the air flow coming out after penetrating through the microphone 13 flows to the bottom of the atomizer 10 firstly, the time of negative pressure induction of the air flow in the microphone 13 and the atomizer 10 is prolonged, and the induction sensitivity of the microphone 13 is reduced; therefore, the microphone starting air passage 19 is perpendicular to the wall of the shell 11 cavity, air is transversely fed, and when the condensed oil atomization core 12 reaches the port of the microphone starting air passage 19 after leaking, the condensed oil atomization core is not easy to enter the microphone starting air passage 19 along the port of the microphone starting air passage 19, the air passage is ensured to be smooth, the air flow negative pressure in the atomizer 10 is quickly induced, and the induction sensitivity of the microphone 13 is ensured.

As shown in fig. 5, the microphone 13 may be arranged vertically, that is, the air inlet surface 131 and the sensing surface 132 of the microphone 13 are respectively arranged vertically to the microphone actuation air passage 19. If miaow head 13 is adopted transversely to put, then miaow head start air way 19 is parallel with miaow head 13's the direction of placing, the negative pressure that the air current formed can be in miaow head 13's response face 132 when the response face 132 of arrival miaow head 13 the top, the rete that is used for the response in the miaow head 13 is relatively weaker to the response of air current negative pressure, atomizer 10 need suck hard and just can have corresponding great air current negative pressure to start miaow head 13, and miaow head 13 vertical setting, miaow head start air way 19 is perpendicular with miaow head 13's response face 132, the air current negative pressure can be fast by miaow head 13's response face 132 discernment response after reacing miaow head start air way 19, this moment, the start-up air current that miaow head 13 needs just is relatively less, consequently, the response is more sensitive. Of course, it is also possible to arrange the microphone 13 in a horizontal manner, and the corresponding suction force is increased.

Further, in this embodiment, the diameter of the microphone starting air passage 19 is smaller than the diameter of the cavity 142 of the microphone protecting structure 14, the cavity 142 of the microphone protecting structure 14 abuts against the side wall between the air inlet surface 131 and the sensing surface 132 of the microphone 13, so that the external air is not easy to enter the microphone starting air passage 19 from the air inlet channel of the microphone 13 through the gap between the air inlet surface 131 of the microphone 13 and the side wall of the sensing surface 132, and the air entering from the air inlet 144 of the microphone protecting structure 14 is introduced into the microphone starting air passage 19 after passing through the middle of the microphone 13; furthermore, the air inlet 144 of the main air passage 22 is communicated with the air inlet 144 of the head restraint structure 14 and the atomizer air inlet 114, and the air outlet of the main air passage 22 is communicated with the atomizing core air inlet 120, wherein the main air passage 22 may be disposed at one side of the head starting air passage 19.

When the suction force of the atomizer 10 is small, the airflow inside the atomizer 10 is in a low negative pressure state, and when the airflow entering from the air inlet 114 of the atomizer is small, the hidden channel at the contact part between the microphone protection structure 14 and the microphone 13 is sealed, the differential pressure induction between the air inlet surface 131 and the induction surface 132 of the microphone 13 is sensitive, and the sensitivity of the microphone 13 is high; when atomizer 10 suction power is said greatly, the inside air current of atomizer 10 is in high negative pressure state, and from the atomizer air inlet 114 entering when being the air current, after the outside air got into, a small part can start the air flue 19 from the miaow head and get into and be used for starting miaow head 13 response, and the majority can directly enter into atomizing core 12 from main air flue 22, is difficult to appear admitting air the not enough condition, guarantees the smog volume after the atomizing.

Fig. 6 is a side view schematically showing the structure of the atomizer according to the first embodiment of the present invention, and fig. 7 is a sectional view of fig. 6 taken along the sectional line C-C', and as shown in fig. 6 and 7, in order to ensure the atomization effect, air may be supplied through the dual main air passages 22. The main air passage 22 comprises a first main air passage 220 and a second main air passage 221, and the first main air passage 220 and the second main air passage 221 are respectively arranged on two sides of the head starting air passage 19; the atomizing core air inlet 120 comprises a first air inlet 121 and a second air inlet 122, one end of the first main air channel 220 is communicated with the atomizer air inlet 114, and the other end is communicated with the first air inlet 121; and one end of the second main air passage 221 is communicated with the atomizer air inlet 114, and the other end is communicated with the second air inlet 122. Thus, compared with a single main air passage 22, the air flow entering the atomizer 10 is relatively larger if the double main air passages 22 are arranged, the air flow entering the atomizing core 12 is also relatively larger, and the concentration of the smoke oil which is mixed by the larger air flow after being atomized in the atomizing core 12 and is sucked through the flue 17 is different, so that the smoke oil can be selected according to the preference of different users. Of course, it is also possible to provide a different size of the main air passage 22 or more main air passages 22.

Further, a microphone inlet channel 10 is formed between the inlet surface 131 of the microphone 13 and the inlet 144 of the microphone protection structure 14, and it can be seen that the distance between the sensing surface 132 of the microphone 13 and the atomizing core inlet 120 is smaller than the distance between the intersection of the microphone inlet channel 20 and the main air duct 22 and the atomizing core inlet 120. That is to say, set up the response surface 132 of miaow head 13 in the position that is higher than the meeting point, the distance apart from atomizing core air inlet 120 is shorter, after inhaling a breath with atomizer 10, begins to form the negative pressure from the gas outlet 145 of atomizer 10, and the negative pressure slowly forms toward atomizer 10 bottom from top to bottom, and this negative pressure reaches the response surface 132 position of miaow head 13 earlier this moment, and consequently the sensitivity of miaow head 13 response is better, guarantees atomization effect.

In order to improve the sensitivity of the sensing of the microphone 13, an air storage cavity 23 may be disposed between the microphone actuation air passage 19 and the microphone 13, wherein the cross-sectional area of the air storage cavity 23 is larger than the cross-sectional area of the microphone actuation air passage 19 and smaller than the sensing surface 132 of the microphone 13. Because the microphone starting air passage 19 is small, the air quantity stored in the microphone starting air passage 19 is small, when the atomizer 10 sucks a breath, negative pressure is formed from the air outlet of the atomizer 10, the negative pressure is slowly formed from top to bottom towards the bottom of the atomizer 10 and reaches the horizontal plane of the microphone 13, the air quantity stored in the microphone starting air passage 19 is small, the negative pressure is not fully contacted with the air in the microphone starting air passage 19, and the negative pressure reaching the sensing surface 132 of the microphone 13 does not reach the sensing of the microphone 13 due to the influence of the airflow of the main air passage 22 on the negative pressure after reaching the atomizing core air inlet 120, so that the sensing sensitivity of the microphone 13 is influenced; therefore, the sensing surface 132 of the microphone 13 is required to be in contact with the negative pressure for sensing, a large negative pressure contact area is needed between the sensing surface 132 of the microphone 13 and the air passage of the microphone 13, and if the contact sensing area between the sensing surface 132 and the negative pressure is set according to the area of the sensing surface 132 of the microphone 13, the tightness of the microphone protection structure 14 to the side wall of the microphone 13 is poor, air leakage can be generated, air entering from the microphone air inlet channel 20 cannot pass through the air inlet surface 131 of the microphone 13, so that the sensing sensitivity of the microphone 13 is also affected, and therefore, the air storage cavity 23 is arranged between the microphone starting air passage 19 and the sensing surface 132 of the microphone 13, and the sensing sensitivity of the microphone 13 can be guaranteed.
