For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0053] like Figure 1 As shown, an embodiment of the present application provides an electronic atomization device 100, which relates to the technical field of electronic atomization and is used to atomize an aerosol matrix to form an aerosol for use by a user.

[0054] like Figures 1 to 3 As shown, the electronic atomization device 100 provided in this embodiment includes an air intake bracket 110 and an atomization assembly 120 .

[0055] The air intake bracket 110 defines an air intake channel 111, the atomizer assembly 120 has an atomizer channel 1251, the air intake bracket 110 and the atomizer assembly 120 are connected and jointly define a receiving chamber 112, a guide structure 113 and a liquid blocking structure 114 are provided in the receiving chamber 112, the guide structure 113 is used to separate the receiving chamber 112 into a guide groove 1121 and a first mounting groove 1122, the guide groove 1121 is connected between the air intake channel 111 and the atomizer channel 1251. An adsorption element 115 is provided in the first mounting groove 1122, the guide groove 1121 is connected to the first mounting groove 1122, and the liquid blocking structure 114 is located at the connecting position between the air intake channel 111 and the guide groove 1121, and is used to partially cover the guide groove 1121.

[0056] Exemplarily, the adsorption element 115 may be a component capable of absorbing liquid, such as absorbent cotton and absorbent fiber.

[0057] It should be noted that the atomizing assembly 120 is used to store aerosol matrix and can atomize the aerosol matrix into aerosol. The guiding structure 113 is used to guide the airflow in the air inlet channel 111 through the guiding groove 1121 into the atomizing channel 1251 to participate in the aerosol generation process.

[0058] In addition, the liquid blocking structure 114 partially blocks the guide groove 1121, which means that the liquid blocking structure 114 does not completely block the guide groove 1121, so that the guide groove 1121 and the air inlet channel 111 are in a connected state, thereby not affecting the airflow in the air inlet channel 111 to enter the atomization channel 1251 through the guide groove 1121.

[0059] It should be mentioned that in the related art, the electronic atomization device takes in air through the air inlet channel of the air inlet bracket, atomizes the aerosol matrix into aerosol through the atomization component, and then discharges the aerosol to the outside through the atomization channel in the atomization component for the user to inhale. In this process, a part of the aerosol will be cooled and liquefied in the atomization channel to form condensate. These residual condensate can be easily inhaled by the user and affect the taste, or flow to the air inlet channel to affect the air intake, thereby affecting the performance of the electronic atomization device and the user's experience.

[0060] It can be understood that in the electronic atomization device 100 provided in this embodiment, since the guide structure 113 divides the accommodating chamber 112 into the guide groove 1121 and the first installation groove 1122, and the guide groove 1121 is respectively connected to the air inlet channel 111 and the first installation groove 1122, on this basis, an adsorption element 115 is provided in the first installation groove 1122, and the liquid blocking structure 114 is located at the connecting position of the air inlet channel 111 and the guide groove 1121, which is used to partially block the guide groove 1121. In this way, the guide groove 1121 can collect the condensate in the atomization channel 1251, and introduce the collected condensate into the first installation groove 1122, so that the condensate is absorbed and stored by the adsorption element 115, and under the shielding of the liquid blocking structure 114, the possibility of the condensate flowing from the atomization channel 1251 into the air inlet channel 111 is reduced. As a result, the influence of the condensate on the taste and air intake of the aerosol can be effectively improved, and the performance of the electronic atomization device 100 and the user experience are improved.

[0061] like Figure 4 As shown, in one embodiment, the guide structure 113 includes two first guide portions 1131, the liquid blocking structure 114 and the two first guide portions 1131 are both arranged at one end of the air intake bracket 110 facing the atomization assembly 120, the air intake bracket 110 and the two first guide portions 1131 jointly define a guide groove 1121, the liquid blocking structure 114 and the two first guide portions 1131 jointly define an overflow channel 1141, and the end of the guide groove 1121 away from the atomization channel 1251 is connected to the first mounting groove 1122 through the overflow channel 1141.

[0062] In this embodiment, since the liquid blocking structure 114 and the two first guide parts 1131 jointly define the overflow channel 1141, the end of the guide groove 1121 away from the atomization channel 1251 is connected to the first installation groove 1122 through the overflow channel 1141. In this way, after the condensed liquid in the atomization channel 1251 is collected by the guide groove 1121, it flows into the first installation groove 1122 through the overflow channel 1141 under the obstruction of the liquid blocking structure 114, and is thereby absorbed and stored by the adsorption element 115, thereby achieving effective collection of the condensed liquid.

[0063] like Figure 4 As shown, further, the two first guide portions 1131 are alternately provided with second guide portions 1132 on one side of the guide groove 1121, and two adjacent second guide portions 1132 are staggered to separate the guide groove 1121 into a plurality of sub-guide grooves connected in sequence.

[0064] For example, one of the first guide portions 1131 is provided with one second guide portion 1132, and another first guide portion 1131 is provided with two second guide portions 1132. The number of the second guide portions 1132 on each first guide portion 1131 can be set according to design requirements, and is not specifically limited here.

[0065] In the present embodiment, since the second guide portions 1132 are alternately arranged on one side of the two first guide portions 1131 facing the guide groove 1121, and the two adjacent second guide portions 1132 are staggered, when the condensate flows into the guide groove 1121 from the atomization channel 1251, it can slowly flow through the multiple sub-guide grooves in sequence in a serpentine path until it flows into the first installation groove 1122 from the overflow channel 1141 and is absorbed by the adsorption element 115. In this way, the condensate can be better collected, thereby improving the influence of the condensate on the taste and performance of the aerosol inhalation.

[0066] like Figure 4 As shown, further, the angle between the two first guide portions 1131 is α, which satisfies: 0°<α<180°.

[0067] Exemplarily, α can be selected from any value of 1°, 5°, 8°, 10°, 15°, 20°, 30°, 45°, 60°, 90°, 120°, 135°, 145°, 170°, 179° or any value in a range consisting of two of them.

[0068] In this embodiment, by controlling the angle α between the two first guide portions 1131 within the range of 0° to 180°, the volume of the guide groove 1121 is gradually expanded in the direction approaching the overflow channel 1141. This can reduce the flow rate of the condensate flowing toward the overflow channel 1141, allowing the condensate to be slowly absorbed by the adsorption element 115, thereby better collecting the condensate.

[0069] like Figure 4 As shown, further, the groove wall of the guide groove 1121 away from the atomization channel 1251 is the bottom wall 11211, and the bottom wall 11211 is inclined relative to the atomization channel 1251 toward the direction close to the air inlet channel 111. In this way, the phenomenon that the condensate accumulates at the end where the guide groove 1121 and the atomization channel 1251 are connected can be improved, so that the condensate can be better absorbed and stored by the adsorption element 115.

[0070] like Figure 4 As shown, further, the two first guide portions 1131 are spaced apart from one end of the liquid blocking structure 114 to form an overflow port 11212 , and one end of the guide groove 1121 away from the overflow channel 1141 is connected to the first installation groove 1122 through the overflow port 11212 .

[0071] In this embodiment, since the two first guide portions 1131 are spaced apart from one end of the liquid blocking structure 114 and form an overflow port 11212, the end of the guide groove 1121 away from the overflow channel 1141 is connected to the first installation groove 1122 through the overflow port 11212. In this way, after the condensate in the atomization channel 1251 is collected by the guide groove 1121, it can flow into the first installation groove 1122 through the overflow port 11212, and then be absorbed and stored by the adsorption element 115, thereby realizing the collection of the condensate.

[0072] like Figure 2 and Figure 5 As shown, in one embodiment, the atomizer assembly 120 includes: a liquid storage housing 121 , a first sealing element 122 , a second sealing element 123 , a liquid storage element 124 , an atomizer core 125 and a liquid guide element 126 .

[0073] Among them, the liquid storage shell 121 has a liquid storage cavity 1211 and a first opening 1212 and a second opening 1213 respectively connected to the liquid storage cavity 1211. The first sealing element 122 is blocked at the first opening 1212, and the second sealing element 123 is blocked at the second opening 1213. The second sealing element 123 and the air inlet bracket 110 are connected and jointly define the accommodating cavity 112. The liquid storage element 124 is arranged in the liquid storage cavity 1211 for storing the aerosol matrix. The atomization core 125 is provided with an atomization channel 1251, at least part of the atomization core 125 is located in the liquid storage cavity 1211, and the atomization core 125 is respectively penetrated by the first sealing element 122, the liquid storage element 124 and the second sealing element 123. The liquid guiding element 126 is connected between the outer peripheral side of the atomization core 125 and the liquid storage element 124, and is used to guide the aerosol matrix into the atomization channel 1251.

[0074] For example, the sealing element may be a sealing silicone, sealing rubber or other elastic component. The liquid storage element 124 may be a liquid storage cotton, liquid storage fiber or other component capable of absorbing liquid. The liquid conducting element 126 may be a liquid conducting cotton, liquid conducting fiber or other component capable of absorbing liquid.

[0075] It should be noted that the first sealing element 122 is sealed at the first opening 1212 , and the second sealing element 123 is sealed at the second opening 1213 , thereby sealing the liquid storage cavity 1211 to effectively reduce the possibility of leakage of aerosol matrix from the liquid storage shell 121 .

[0076] In this embodiment, the aerosol matrix stored in the liquid storage element 124 can be introduced into the atomization channel 1251 of the atomization core 125 through the liquid guide element 126. When the user starts the electronic atomization device 100, the external airflow passes through the air inlet channel 111 and the guide groove 1121 in sequence and enters the atomization channel 1251. The atomization core 125 can heat the aerosol matrix, so that the aerosol matrix is ​​atomized to form an aerosol, and the aerosol is discharged to the outside through the atomization channel 1251 for the user to inhale. In this process, a part of the aerosol will cool and liquefy to form condensate. The condensate flows into the guide groove 1121 due to gravity, and then flows into the first installation groove 1122 to be absorbed and stored by the adsorption element 115. This can improve the phenomenon that the condensate is inhaled by the user together with the aerosol and the condensate flows into the air inlet channel 111 to affect the air intake.

[0077] like Figures 3 to 5As shown, further, a mounting boss 116 is provided in the accommodating cavity 112, and the mounting boss 116 is provided with a second mounting groove 1161 and a notch 1162 connected to the second mounting groove 1161, an airflow sensor 117 is provided in the second mounting groove 1161, and a detection channel 1231 is provided on the side of the second sealing element 123 facing the air intake bracket 110, one end of the detection channel 1231 is connected to the air intake channel 111, an end of the detection channel 1231 away from the air intake channel 111 is connected to the notch 1162, and the detection channel 1231 is connected to the first mounting groove 1122 on the side facing the air intake bracket 110.

[0078] Exemplarily, the airflow sensor 117 may be a microphone, a pressure difference sensor, a flow sensor, or other element capable of detecting airflow parameters.

[0079] It is understandable that after the external airflow enters the air intake channel 111, a part of the airflow enters the atomization channel 1251 through the guide groove 1121, and the other part of the airflow enters the second installation groove 1161 through the detection channel 1231 and the notch 1162 to be detected by the airflow sensor 117. In other words, the airflow is divided into two paths after passing through the air intake channel 111, and the detection channel 1231 is connected to the first installation groove 1122 on the side facing the air intake bracket 110, so that the adsorption element 115 can also collect the condensate in the detection channel 1231, which has the effect of drying the detection channel 1231. In this way, the influence of the condensate on the airflow sensor 117 can be effectively improved, and the detection accuracy of the airflow sensor 117 for the airflow is improved.

[0080] like Figures 6 to 8 As shown, in one embodiment, the electronic atomization device 100 further includes: a main shell 130 , a suction nozzle 140 , an end cover 150 and a third sealing element 160 .

[0081] Among them, the main shell 130 has an installation cavity 131 and a third opening 132 communicated with the installation cavity 131, the air inlet bracket 110 and the atomizer assembly 120 are both arranged in the accommodating cavity 112, and the air inlet bracket 110 is located between the atomizer assembly 120 and the third opening 132. The suction nozzle 140 is arranged at one end of the main shell 130 away from the third opening 132, and the interior of the suction nozzle 140 is communicated with one end of the atomizer channel 1251 away from the air inlet bracket 110. The end cover 150 is provided with an air inlet hole 1511, and is connected to one end of the main shell 130 having the third opening 132 to cover the third opening 132. The third sealing element 160 is blocked at one end of the air inlet channel 111 away from the atomizer assembly 120, and is provided with a through hole 161, one end of the through hole 161 is communicated with the air inlet channel 111, and one end of the through hole 161 away from the air inlet channel 111 is communicated with the air inlet hole 1511.

[0082] Exemplarily, the third sealing element 160 may be an elastic component such as sealing silica gel or sealing rubber.

[0083] In the present embodiment, since the third sealing element 160 blocks the end of the air inlet channel 111 away from the atomization assembly 120 and is provided with a through hole 161, and one end of the through hole 161 is connected to the air inlet channel 111, and the end of the through hole 161 away from the air inlet channel 111 is connected to the air inlet hole 1511, the situation of insufficient air intake caused by leakage of external airflow from the air inlet hole 1511 into the air inlet channel 111 can be reduced, thereby improving the performance of the electronic atomization device 100.

[0084] like Figure 2 , Figure 4 and Figure 7 As shown, it should be noted that when the mounting boss 116 and the airflow sensor 117 are provided in the accommodating cavity 112, the air intake bracket 110 defines an installation space 118, and the installation space 118 is used to place the battery 119. The mounting boss 116 is provided with a vent hole 1163 connected to the second mounting groove 1161, and the vent hole 1163 is connected to the installation space 118. The end cover 150 is provided with a charging port 1513, and the charging port 1513 is connected to the installation space 118.

[0085] It can be understood that since the second installation groove 1161 is connected to the external environment through the vent hole 1163, the installation space 118, and the charging port 1513 in sequence, after the airflow sensor 117 detects the airflow parameters, the second installation groove 1161 can be restored to atmospheric pressure, thereby improving the detection accuracy of the airflow sensor 117 for the airflow.

[0086] like Figures 9 to 11 As shown, further, the end cover 150 has an air intake direction X and a projection plane perpendicular to the air intake direction X, and the electronic atomization device 100 also includes a mounting member 170 and a rotating member 180 .

[0087] The mounting member 170 is located on the side of the end cover 150 facing the air intake bracket 110, and the third sealing element 160 is mounted on the mounting member 170. The rotating member 180 is located on the side of the third sealing element 160 away from the air intake bracket 110, and is rotatably arranged on the mounting member 170, so that the rotating member 180 can rotate relative to the end cover 150 and the third sealing element 160 along a preset direction Y, and the preset direction Y is perpendicular to the air intake direction X. The rotating member 180 is provided with a plurality of air adjustment holes 1811 passing through it, and the plurality of air adjustment holes 1811 are distributed along the preset direction Y, and the orthographic projection areas of two adjacent air adjustment holes 1811 on the projection plane are different, and the air intake hole 1511 is connected to the through hole 161 through one of the air adjustment holes 1811. When the rotating member 180 rotates a preset angle relative to the end cover 150 along the preset direction Y, the air intake hole 1511 can be aligned from one air adjustment hole 1811 to another adjacent air adjustment hole 1811.

[0088] Exemplarily, the number of the air adjustment holes 1811 can be set to two, three, four, five, etc., and can be specifically set according to the aerosol output requirements of the electronic atomization device 100. No specific limitation is made on the number of the air adjustment holes 1811 herein.

[0089] It should be mentioned that the current electronic atomization device has a constant air intake at the air inlet and cannot be adjusted, which results in the aerosol output at the nozzle being unable to be adjusted, affecting the user experience.

[0090] In this embodiment, since the rotating member 180 can rotate relative to the end cover 150 along the preset direction Y, and the orthographic projection areas of two adjacent air adjustment holes 1811 on the rotating member 180 on the projection plane are different, by rotating the rotating member 180 along the preset direction Y, the air inlet holes 1511 are aligned to different air adjustment holes 1811, so that the air intake at the position of the air inlet holes 1511 can be adjusted, so that the aerosol output of the electronic atomization device 100 can be adjusted, which can better meet the user's usage needs and improve the user's usage experience and the market competitiveness of the product.

[0091] like Fig.12 and Fig.13 As shown, in a specific embodiment, the end cover 150 is provided with a first clamping portion 1512, and a plurality of first clamping grooves 1812 are provided on the side of the rotating member 180 facing the end cover 150, and the plurality of first clamping grooves 1812 are distributed along a preset direction Y. When the rotating member 180 rotates along the preset direction Y relative to the end cover 150 by a preset angle, the first clamping portion 1512 can slide out from one first clamping groove 1812 and be clamped into another adjacent first clamping groove 1812.

[0092] Exemplarily, the number of the first card slots 1812 can be set to two, three, four, five, six, etc., which can be specifically set according to the number of the air adjustment holes 1811. No specific limitation is made to the number of the first card slots 1812 herein.

[0093] In this embodiment, since a first clamping portion 1512 is provided on the end cover 150, and a plurality of first clamping grooves 1812 are provided on the side of the rotating member 180 facing the end cover 150, on this basis, the plurality of first clamping grooves 1812 are distributed along a preset direction Y. Thus, when the rotating member 180 rotates by a preset angle along the preset direction Y relative to the end cover 150, the air inlet 1511 can be aligned from one air regulating hole 1811 to another adjacent air regulating hole 1811, and at the same time, the first clamping portion 1512 can slide out from one first clamping groove 1812 and be clamped into another adjacent first clamping groove 1812, which can achieve a positioning effect during the air intake volume adjustment process, so that the air inlet 1511 can be more accurately and quickly aligned to a specific air regulating hole 1811, and the first clamping portion 1512 can provide the user with force feedback and gear sense during the process of sliding out and clamping into the first clamping groove 1812, thereby improving the user's usage experience.

[0094] like Fig.12 and Fig.13 As shown, further, the first clamping portion 1512 and each first clamping groove 1812 are both elliptical, and the orthographic projection areas of the first clamping portion 1512 and the first clamping groove 1812 on the projection plane gradually decrease along the air intake direction X.

[0095] In this embodiment, since the first clamping portion 1512 and each first clamping slot 1812 are both elliptical, and the orthographic projection areas of the first clamping portion 1512 and the first clamping slot 1812 on the projection plane gradually decrease along the air intake direction X, that is, the cross-sectional areas of the first clamping portion 1512 and the first clamping slot 1812 gradually decrease in the air intake direction X, the first clamping portion 1512 is easier to slide out of the first clamping slot 1812 or be clamped into the first clamping slot 1812, thereby improving the smoothness of the first clamping portion 1512 sliding out of and being clamped into the first clamping slot 1812.

[0096] Of course, for the above embodiments, the first clamping portion 1512 and each first clamping slot 1812 may also be circular, polygonal, etc., and the orthographic projection areas of the first clamping portion 1512 and the first clamping slot 1812 on the projection plane gradually decrease along the air intake direction X, which also improves the smoothness of the first clamping portion 1512 sliding out and clamping into the first clamping slot 1812.

[0097] In another specific embodiment, the end cover 150 is provided with a plurality of first card slots 1812 distributed along a preset direction Y, and a first card connection portion 1512 is provided on the side of the rotating member 180 facing the end cover 150. In this way, when the rotating member 180 rotates by a preset angle relative to the end cover 150 along the preset direction Y, the first card connection portion 1512 can slide out from one first card slot 1812 and be snapped into another adjacent first card slot 1812, which can also provide force feedback and gear sense to the user, and facilitate the user to accurately and quickly align the air inlet 1511 to a specific air adjustment hole 1811.

[0098] like Fig.12 and Fig.13 As shown, in a specific embodiment, the end cover 150 includes a cover body 151 and a surrounding plate 152, the surrounding plate 152 is connected to one end of the main shell 130 having a third opening 132, the cover body 151 is provided with an air inlet hole 1511, the surrounding plate 152 and the cover body 151 are connected and jointly define an open cavity 1521, the mounting member 170 and the rotating member 180 are both located on the side of the cover body 151 facing the open cavity 1521, the side of the surrounding plate 152 facing the open cavity 1521 is provided with a first arc guide surface 1522, the side of the rotating member 180 away from the mounting member 170 is provided with a first arc sliding surface 1813, the first arc sliding surface 1813 is fitted to the first arc guide surface 1522, the mounting member 170 is provided with a second arc guide surface 1721, the rotating member 180 is provided with a second arc sliding surface 1814, and the second arc sliding surface 1814 is fitted to the second arc guide surface 1721.

[0099] In the present embodiment, since the rotating member 180 is attached to the first arc guide surface 1522 of the enclosure 152 through the first arc sliding surface 1813, and is attached to the second arc guide surface 1721 of the mounting member 170 through the second arc sliding surface 1814, when the rotating member 180 is rotated, under the guidance of the first arc guide surface 1522 and the second arc guide surface 1721, the rotating member 180 can rotate stably and smoothly along the preset direction Y relative to the end cover 150, so that the air inlet 1511 can be aligned to different air adjustment holes 1811, so as to facilitate the adjustment of the air intake volume.

[0100] like Fig.12 and Fig.13 As shown, further, the mounting member 170 includes a mounting portion 171, a guide portion 172 and two limiting portions 173, the third sealing element 160 is mounted on the mounting portion 171, a second arc guide surface 1721 is provided on the outer peripheral side of the guide portion 172, the two limiting portions 173 are respectively provided on the outer peripheral side of the guide portion 172, and the two limiting portions 173 are spaced apart in the preset direction Y.

[0101] In this embodiment, the guide portion 172 cooperates with the enclosure 152 to guide the rotating member 180 to rotate relative to the rotating member 180 along the preset direction Y. Two limiting portions 173 are provided on the outer peripheral side of the guide portion 172, and the two limiting portions 173 are spaced apart in the preset direction Y. Thus, when the rotating member 180 rotates relative to the end cover 150 along the preset direction Y, the rotating member 180 can abut from one limiting portion 173 to another limiting portion 173 to limit the rotation angle of the rotating member 180 relative to the end cover 150 along the preset direction Y, thereby limiting the position of the rotating member 180. At the same time, the installation portion 171 is provided to facilitate the assembly of the third sealing element 160.

[0102] Furthermore, a plurality of first saw teeth are arranged along the second circular arc guide surface 1721 , a plurality of second saw teeth are arranged along the second circular arc sliding surface 1814 , and a tooth groove is arranged between every two adjacent first saw teeth.

[0103] In this embodiment, by providing the first saw teeth and the second saw teeth, and by providing a tooth groove between each two adjacent first saw teeth, when the rotating member 180 rotates relative to the end cover 150 along the preset direction Y, the second saw teeth can slide out of one tooth groove and snap into another adjacent tooth groove. This can improve the problem of the rotating member 180 not rotating smoothly due to the possible excessive fit between the second arc sliding surface 1814 and the second arc guide surface 1721.

[0104] like Fig.13 As shown, further, the rotating member 180 includes a rotating part 181 and an operating part 182, the rotating part 181 is provided with a first arc sliding surface 1813 and a second arc sliding surface 1814, one end of the operating part 182 is connected to the rotating part 181, the enclosure 152 is provided with an arc-shaped through hole 1523 connected to the open cavity 1521, the rotating part 181 is located in the open cavity 1521, and the part of the operating part 182 away from the rotating part 181 is penetrated by the arc-shaped through hole 1523.

[0105] In this embodiment, an arc-shaped through hole 1523 is provided on the enclosure 152, and one end of the operating portion 182 is connected to the rotating portion 181, and the portion of the operating portion 182 away from the rotating portion 181 is passed through the arc-shaped through hole 1523. In this way, it is convenient for the user to drive the rotating member 180 to rotate relative to the end cover 150 through the operating portion 182, which makes it more convenient to use and improves the user experience.

[0106] like Figures 14 to 17As shown, further, a second clamping portion 1722 is provided on the second arc guide surface 1721, and a plurality of second clamping grooves 1815 are provided along the second arc sliding surface 1814, and the plurality of second clamping grooves 1815 are distributed along the preset direction Y. When the rotating member 180 rotates by a preset angle along the preset direction Y relative to the end cover 150, the second clamping portion 1722 can slide out of one second clamping groove 1815 and clamp into another adjacent second clamping groove 1815.

[0107] Exemplarily, the number of the second slots 1815 can be set to two, three, four, five, etc., which can be specifically set according to the number of the air adjustment holes 1811 and is not limited here.

[0108] In this embodiment, since a second clamping portion 1722 is provided on the second circular arc guide surface 1721, and a plurality of second clamping grooves 1815 are provided on the second circular arc sliding surface 1814, on this basis, the plurality of second clamping grooves 1815 are distributed along a preset direction Y. Thus, when the rotating member 180 rotates by a preset angle along the preset direction Y relative to the end cover 150, the air inlet 1511 can be aligned from one air regulating hole 1811 to another adjacent air regulating hole 1811. At the same time, the second clamping portion 1722 can slide out from one second clamping groove 1815 and clamp into another adjacent second clamping groove 1815. This can achieve a positioning effect during the air intake volume adjustment process, so that the air inlet 1511 can be more accurately and quickly aligned to a specific air regulating hole 1811. In addition, the second clamping portion 1722 can provide the user with force feedback and a sense of gear position during the process of sliding out and clamping into the second clamping groove 1815, thereby improving the user's usage experience.

[0109] It should be understood that in the electronic atomization device 100 provided in this embodiment, the combination of the first clamping portion 1512 and the first clamping slot 1812 can be set separately, or the combination of the second clamping portion 1722 and the second clamping slot 1815 can be set separately. Of course, the second clamping portion 1722 and the second clamping slot 1815 can also be set while the first clamping portion 1512 and the first clamping slot 1812 are set, which are all within the scope of the present application.

[0110] In another specific embodiment, a rotating shaft is provided on the side of the end cover 150 facing the rotating member 180. The rotating member 180 is hinged on the rotating shaft and can rotate around the rotating shaft along a preset direction Y, so that the rotating member 180 can also rotate relative to the end cover 150, thereby facilitating the alignment of the air inlet hole 1511 to different air adjustment holes 1811 to achieve the adjustment of the air intake volume.

[0111] like Fig.13 and Fig.17As shown, in a specific embodiment, the air inlet hole 1511 and each air regulating hole 1811 are circular, and the aperture of each air regulating hole 1811 is smaller than or equal to the aperture of the air inlet hole 1511 .

[0112] In the present embodiment, since the air inlet hole 1511 and each air adjusting hole 1811 are circular, and the orthographic projection areas of two adjacent air adjusting holes 1811 on the projection plane are different, the apertures of the two adjacent air adjusting holes 1811 are different. On this basis, the aperture of each air adjusting hole 1811 is less than or equal to the aperture of the air inlet hole 1511. In this way, the air intake volume when the air inlet hole 1511 is aligned to different air adjusting holes 1811 is different. The user can adjust the air intake volume of the air inlet hole 1511 by rotating the rotating part 180, so that the aerosol output at the nozzle 140 position of the electronic atomization device 100 can be adjusted, thereby better meeting the user's usage needs.

[0113] Of course, for the above embodiments, the air inlet hole 1511 and each air adjustment hole 1811 may also be elliptical or polygonal such as a square, rectangle, hexagon, etc. When the air inlet hole 1511 is aligned to different air adjustment holes 1811, the air intake volume can also be adjusted. No specific restrictions are made on the shapes of the air inlet hole 1511 and the air adjustment hole 1811.

[0114] like Fig. 9 and Fig.11 As shown, in a specific embodiment, a plurality of air regulating holes 1811 are spaced apart in a preset direction Y, and the air intake volume can be adjusted by rotating the rotating member 180 so that the air intake holes 1511 are aligned to different positions of the air regulating holes 1811 .

[0115] Of course, for the above embodiment, multiple air adjustment holes 1811 can also be connected in sequence in the preset direction Y to form an arc-shaped hole with a gradually changing cross-sectional area, that is, the orthographic projection area of ​​the arc-shaped hole on the projection plane gradually changes along the preset direction Y. In this way, by rotating the rotating part 180, the orthographic projection area of ​​the arc-shaped hole aligned with the air inlet hole 1511 changes, so the air intake volume can also be adjusted.
