[0053] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0054] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0055] See also Figures 1 to 4 The first exemplary electronic atomization device 10 provided by an embodiment of the present invention includes a power supply assembly 20, an atomizer 30 and a buffer plug 300. The power supply assembly 20 is used to supply power to the atomizer 30. The atomizer 30 can convert electrical energy into heat energy, thereby atomizing the liquid in the atomizer 30 to form smoke that can be inhaled by the user. The atomized liquid can be an aerosol generation matrix, etc. The power supply assembly 20 includes a housing 100 and a battery 200.

[0056] See also Figures 1 to 5In some examples, an air inhalation channel 31 is provided in the atomizer 30, and the air inhalation channel 31 is connected to the outside. The housing 100 has a first end wall 111 and a second end wall 112 arranged opposite to each other, the first end wall 111 is arranged close to the atomizer 30, and the second end wall 112 is arranged away from the atomizer 30. In other words, the first end wall 111 is closer to the atomizer 30 than the second end wall 112. The housing 100 is provided with a functional channel, a receiving chamber 110 and an air inlet channel 120 which are connected in sequence. Among them, the functional channel includes an air guide channel 130 which passes through the first end wall 111 and is connected to the air inhalation channel 31, and a sub-cavity 101 which is located on the side of the first end wall 111 away from the atomizer 30. The sub-cavity 101 can be regarded as a space formed by the first end wall 111 being recessed or deformed toward the atomizer 30, and this space is used to accommodate the buffer plug 30. This space is open in the direction away from the atomizer 30 so that the air guide channel 130 is connected to the receiving chamber 110. A portion of the accommodating chamber 110 is used to accommodate the battery 200, and the remaining portion of the accommodating chamber 110 is used to transmit gas. The air inlet channel 120 is opened on the second end wall 112 and connects the outside and the accommodating chamber 110. During the inhalation process, the outside gas enters from the air inlet channel 120 and passes through the accommodating chamber 110 and the functional channel in sequence to reach the inhalation channel 31. The gas entering the inhalation channel 31 will carry smoke to be inhaled by the user.

[0057] In some examples, the buffer plug 300 is a silicone buffer plug 300, that is, the buffer plug 300 is made of silicone material, so that the buffer plug 300 has a certain flexibility and is elastically connected to the housing 100. Figure 6 and Figure 7 As shown, the buffer plug 300 includes a sealing portion 310 and a mounting portion 320, wherein the sealing portion 310 is a block structure, and the mounting portion 320 is roughly a U-shaped strip structure. The sealing portion 310 is connected to the middle portion of the mounting portion 320. The sealing portion 310 is located in the sub-cavity 101 and is arranged opposite to the air guide channel 130, that is, the sealing portion 310 is located on the side of the first end wall 111 away from the atomizer 20. A mounting hole 113 is provided on the housing 100, and the two ends of the mounting portion 320 are inserted into the mounting hole 113, so as to fix the mounting portion 320 on the housing 100. More specifically, the mounting hole 113 can be provided on the side of the first end wall 111 away from the atomizer 30.

[0058] When the battery 200 is normal, that is, the battery 200 is in a normal state, when the user draws air in the air intake channel 31, the difference between the air pressure in the accommodating chamber 110 and the air pressure in the air intake channel 31 is less than the threshold pressure, the buffer plug 300 is in the first position, and the sealing portion 310 forms a certain gap between the first position and the first end wall 111, so that the sealing portion 310 does not block the air guide channel 130, ensuring that the accommodating chamber 110 is connected to the air guide channel 130 and the sub-cavity 101 through the air guide channel 31, and the gas in the accommodating chamber 110 can enter the air intake channel 31 from the air guide channel 130 during suction. When the battery 200 is abnormal (such as explosion), that is, the battery 200 is in an abnormal state of explosion, a strong high-pressure gas is formed in the accommodating chamber 110. Due to the effect of the high-pressure gas, the difference between the air pressure in the accommodating chamber 110 and the air pressure in the air inhalation channel 31 is greater than the threshold pressure, and the buffer plug 300 itself will produce elastic deformation and move from the first station to the second station, so that the sealing part 310 can press against the first end wall 111 in the second station, thereby immediately forming a blocking effect on the air guide channel 130, and the high-temperature gas and harmful substances generated by the explosion of the battery 200 will not be able to enter the air inhalation channel 31 from the accommodating chamber 110 through the air guide channel 130, thereby preventing them from being inhaled by the user, thereby improving the safety performance of the entire electronic atomization device 10. At the same time, the high-pressure gas in the accommodating chamber 110 can be discharged from the air inlet channel 120 to prevent the gas in the accommodating chamber 110 from impacting the air inhalation channel 31, thereby improving the safety performance of the electronic atomization device 10 to a certain extent.

[0059] Of course, the buffer plug 300 can also be elastically connected to the housing 100 through a spring. When the difference between the air pressure in the accommodating chamber 110 and the air pressure in the air suction channel 31 is greater than the threshold pressure, the spring produces elastic deformation, while the buffer plug 300 itself does not produce elastic deformation, so that the buffer plug 300 can overcome the elastic resistance of the spring and move from the first station to the second station. The threshold pressure can range from 1KPa to 2MPa, and its specific value can be 1KPa, 2KPa, 1.5MPa or 2MPa. The threshold pressure can also range from 2KPa to 2MPa, or from 10KPa to 1MPa. When the threshold pressure is 10KPa to 1MPa, on the one hand, it can prevent the user's suction force from being too large, causing the buffer plug 300 to move from the first station to the second station, and on the other hand, it can make the buffer plug 300 move from the first station to the second station in time to block the air guide channel 130 in the early stage of the battery 200 explosion.

[0060] See also Figure 7 and Fig. 9A recessed groove 311 is formed on the surface of the sealing portion 310 facing the first end wall 111, and the recessed groove 311 is arranged opposite to the gas guide channel 130. In the abnormal state of the battery 200 exploding, the thickness of the portion of the sealing portion 310 corresponding to the recessed groove 311 is relatively thin and relatively easier to deform. When the surface of the sealing portion 310 abuts against the first end wall 111, the bottom wall of the recessed groove 311 can be pushed into the gas guide channel 130 by the pressure of the high-pressure gas, thereby further enhancing the sealing performance of the sealing portion 310 on the gas guide channel 130.

[0061] like Figure 8 As shown, the second end wall 112 is provided with a fixing hole 112a, which connects the accommodating chamber 110 and the air inlet passage 120. The power supply assembly 20 further includes a pressure reducing plug 400, which is arranged at the fixing hole 112a. The pressure reducing plug 400 is made of a silicone material, so that the pressure reducing plug 400 has a certain degree of flexibility. Fig. 9 and Fig.10 As shown, the pressure reducing plug 400 includes a sleeve 420, a lug 430 and a leaflet 410. The sleeve 420 is inserted into the fixing hole 112a in the axial direction, and the number of the lugs 430 is two, which are arranged opposite to each other. The two lugs 430 are arranged at the same end of the sleeve 420 and extend out in the circumferential direction to be fixedly connected with the second end wall 112, so as to realize the installation of the pressure reducing plug 400 on the housing 100.

[0062] like Fig.10 and Fig.11 As shown, the sleeve 420 is arranged to form a through hole 421, and the number of the flaps 410 is multiple, and the multiple flaps 410 are arranged on the side wall of the through hole 421 at intervals along the circumferential direction, and all the flaps 410 can at least cover part of the through hole 421, and the shape of the flaps 410 can be fan-shaped. Under normal conditions, the air pressure difference acting on the flaps 410 is lower than the set value, and all the flaps 410 are arranged horizontally and can cover part of the through hole 421, and a narrow gap 411 is formed between two adjacent flaps 410.

[0063] In an abnormal state such as an explosion of the battery 200, the high-pressure gas in the accommodating chamber 110 will exert a strong pressure on the flaps 410. The pressure difference acting on the flaps 410 is higher than the set value, so that the horizontally arranged flaps 410 swing toward the air inlet channel 120 to a vertical setting and adhere to the side wall of the through hole 421. The gap 411 between the flaps 410 expands, and the entire through hole 421 will be completely open. The through hole 421 is a decompression channel 421a, which connects the accommodating chamber 110 and the air inlet channel 120. The high-pressure gas in the accommodating chamber 110 will be discharged from the air inlet channel 120 through the through hole 421 (decompression channel 421a). Since the pressure reducing channel 421a is provided and the air intake channel 120 includes a connecting section 121 directly connected to the accommodating chamber 110, the high-pressure gas in the accommodating chamber 110 can enter the air intake channel 120 from the through hole 421 in addition to entering the entire air intake channel 120 from the connecting section 121, thereby increasing the gas discharge path, so that the high-pressure gas in the accommodating chamber 110 can be quickly discharged from the air intake channel 120 in a short time, further preventing the gas in the accommodating chamber 110 from impacting in the direction of the gas guide channel 130.

[0064] When the leaflets 410 are fan-shaped, the gaps 411 formed between all the leaflets 410 will be radial, that is, one end of all the gaps 411 is located on the central axis of the sleeve 420, and the other ends of the gaps 411 are evenly distributed on the same circumference. For example, when the number of leaflets 410 is four, the gaps 411 will be cross-shaped and radial, and the lines connecting the positions of the other ends of the gaps 411 form a square. For another example, when the number of leaflets 410 is three, the lines connecting the positions of the other ends of the gaps 411 form an equilateral triangle; when the number of leaflets 410 is six, the lines connecting the positions of the other ends of the gaps 411 form a regular hexagon.

[0065] See also Figures 2 to 4 In some examples, the power supply assembly 20 also includes a USB charging plug 520, which is disposed in the air intake passage 120. When the USB charging plug 520 is connected to an external charging device through the power supply assembly 20 line, the external charging device can charge the battery 200 through the USB charging plug 520, so that the battery 200 can be recycled multiple times.

[0066] like Figure 4As shown in , in some examples, the housing 100 includes a first abutting portion 141 and a second abutting portion 142, the number of the first abutting portion 141 and the second abutting portion 142 are two respectively, the two first abutting portions 141 are arranged opposite to each other in the left and right directions, the two second abutting portions 142 are arranged opposite to each other in the front and back directions, the second abutting portion 142 is connected between the first abutting portions 141, and the second abutting portions 142 and the second abutting portions 142 are jointly arranged to form a receiving hole 140, and the atomizer 30 is received in the receiving hole 140. The first abutting portion 141 protrudes a first length h relative to the bottom wall of the receiving hole 140, and the second abutting portion 142 protrudes a second length H relative to the bottom wall of the receiving hole 140, and the second length H is greater than the first length h. When the atomizer 30 is located in the receiving hole 140, the atomizer 30 abuts against the tops of the first abutting portion 141 and the second abutting portion 142 at the same time, that is, the first abutting portion 141 and the second abutting portion 142 can limit the installation of the atomizer 30. Figure 3 As shown in FIG. 1 , a groove 32 is formed on the side circumference of the atomizer 30 , and the second abutting portion 142 can cooperate with the groove 32 .

[0067] See also Fig.12 and Fig.13 In some examples, a detachable connection is formed between the atomizer 30 and the housing 100. For example, the power supply assembly 20 further includes a magnetic member 510, which may be a permanent magnet. The magnetic member 510 may be embedded in the housing 100, and the surface of the magnetic member 510 may be flush with the bottom wall of the receiving hole 140. When the atomizer 30 is received in the receiving hole 140, the magnetic member 510 forms a certain magnetic attraction force on the atomizer 30, so that the atomizer 30 is stably and reliably fixed on the housing 100, which is also conducive to the installation and removal of the atomizer 30 on the housing 100.

[0068] See also Fig.14 Of course, the air inlet channel 120 of the second example electronic atomization device provided in this embodiment is not provided on the power supply assembly 20, but directly provided on the atomizer 30. The other structures of the second example electronic atomization device are the same as those of the first example electronic atomization device 10. Therefore, when the air inhalation channel 31 is inhaled, the external gas does not need to enter the air inhalation channel 31 from the air inlet channel 120 through the accommodating chamber 110 and the air guide channel 130, but directly enters the air inhalation channel 31 through the air inlet channel 120 on the atomizer 30.

[0069] The present invention also provides a power supply component, the power supply component includes the embodiment as shown in Figures 1 to 13The housing 100, battery 200 and buffer plug 300 shown in the figure. The housing 100 of the power supply assembly 20 may be provided with an air inlet channel 120, a receiving chamber 110, a sub-chamber 101 and an air guide channel 130. When the air inlet channel 31 is sucked, the external gas enters the air inlet channel 31 through the receiving chamber 110, the sub-chamber 101 and the air guide channel 130 from the air inlet channel 120. Of course, it may also be as Fig.14 As shown in , the housing 100 of the power supply assembly may not have an air inlet passage 120 .

[0070] like Fig.15 and Fig.16 As shown, a first exemplary electronic atomization device 10 provided by another embodiment of the present invention includes an atomizer 700, a buffer plug 800 and a power supply assembly 900. The atomizer 700 includes a shell assembly 600, an atomization assembly 710 and a base assembly 720. The power supply assembly 900 includes a housing 910 and a battery 21, and the housing 910 is provided with a receiving cavity 911, and the battery 21 is located in the receiving cavity 911. The housing assembly 600 can be integrally formed with the housing 910, and the atomizer 700 can atomize a liquid represented by an aerosol generating matrix to form a smoke for the user to inhale.

[0071] See also Fig.15 and Fig.16 In some examples, the housing assembly 600 may be roughly tubular, and the housing assembly 600 includes a shell 610 and a nozzle 620. The shell 610 forms a tube cavity, and the atomizer assembly 710 and the base assembly 720 are accommodated in the tube cavity. The nozzle 620 is inserted at the end of the housing 610, and an air inhalation hole 621 connected to the outside is opened at the nozzle 620. The smoke formed by the atomizer 700 atomizing the liquid flows through the air inhalation hole 621, and the user inhales the smoke in the air inhalation hole 621 at the nozzle 620.

[0072] See also Fig.16 and Fig.17 In some examples, the atomization assembly 710 includes a heating unit 750 and a liquid storage unit 760. The liquid storage unit 760 includes a glass fiber tube 762 and a liquid storage member 761. The glass fiber tube 762 has good structural strength. The glass fiber tube 762 is arranged to form a channel 640 for gas circulation. The channel 640 is connected to the air intake hole 621 and together forms an air intake channel 601. The air intake channel 601 is used for gas and smoke to pass through. The gas and smoke in the air intake channel 601 can be sucked by the user at the air intake hole 621. The liquid storage member 761 is sandwiched between the glass fiber tube 262 and the outer shell 610. The liquid storage member 761 can be made of cotton products. The liquid can penetrate into the liquid storage member 761, so that the liquid storage member 761 has a storage function for the liquid. The heating unit 750 includes a liquid guide strip 752 and a heating wire 751. The heating wire 751 can be spiral, see Fig.18 and Fig. 22 , the heating wire 751 is wound around the middle of the liquid-conducting strip 752 and is located in the air intake channel 601, the heating wire 751 is connected to the battery 21, and when the battery 21 supplies power to the heating wire 751, the heating wire 751 generates heat. The two ends of the liquid-conducting strip 752 respectively pass through the glass fiber tube 262 and are inserted into the liquid storage part 261. For example, the liquid-conducting strip 752 may include a horizontal strip 752a and two vertical strips 752b, the two vertical strips 752b are respectively connected to the two ends of the horizontal strip 752a and extend toward the same side of the horizontal strip 752a, so that the liquid-conducting strip 752 forms a U-shaped structure, the horizontal strip 752a is located in the air intake channel 601, the heating wire 751 is wound around the horizontal strip 752a, and the two vertical strips 752b are respectively inserted into the liquid storage part 261. The entire liquid guiding strip 752 has a good liquid guiding function, and the liquid in the liquid storage member 761 is transferred to the horizontal strip 752a through the vertical strip 752b. When the heating wire 751 generates heat, the heating wire 751 atomizes the liquid on the horizontal strip 752a to form smoke for the user to inhale.

[0073] See also Fig.16 and Fig.17 In some examples, the base assembly 720 includes a mounting portion 722 and an insertion portion 721 connected to each other, the cross-sectional dimension of the mounting portion 722 is larger than the cross-sectional dimension of the insertion portion 721, the mounting portion 722 and the insertion portion 721 are coaxially arranged, and the battery 21 is arranged opposite to the mounting portion 722, for example, the battery 21 is located below the mounting portion 722. The insertion portion 721 is inserted into the air inlet channel 601. See also Fig.19 and Fig. 20 A large hole 742 is provided in the mounting portion 722, and a small hole 741 is provided in the insertion portion 721. Obviously, the cross-sectional size (caliber) of the large hole 742 is larger than the cross-sectional size (caliber) of the small hole 741. The large hole 742 and the small hole 741 can both be coaxially arranged circular holes, etc. At this time, the large hole 742 and the small hole 741 together form a stepped hole, and the top wall 742a of the large hole 742 forms a stepped surface.

[0074] See also Fig.19 and Fig. 20 In some examples, the buffer plug 800 may be a silicone plug, that is, the buffer plug 800 may be made of silicone material, and the buffer plug 800 is located in the large hole 742, and the position where the buffer plug 800 maintains a set distance from the top wall 742a of the large hole 742 is defined as the first station 11, and the position where the buffer plug 800 abuts against the top wall 742a of the large hole 742 is defined as the second station 12. In order to fix the buffer plug 800 on the base assembly 720, the buffer plug 800 may include a cylindrical first blocking portion 810, and the first blocking portion 810 forms an interference fit relationship with the large hole 742.

[0075] A flow guide channel is formed between the side wall of the large hole 742 and the outer wall of the buffer plug 800. The large hole 742, the small hole 741 and the flow guide channel together form a functional channel 740 for gas to pass through. Fig.17 and Fig.18 The air inlet passage 120 is opened on the housing 910 (such as Fig.15 ), the air inlet channel 120 is connected with the accommodating chamber 911, and the functional channel 740 is connected with the accommodating chamber 911 and the air inhalation channel 601 at the same time. When the user inhales at the air inhalation hole 621, the external gas enters the air inhalation channel 601 through the air inlet channel 120, the accommodating chamber 911, and the functional channel 740 in sequence. Finally, the external gas entering the air inhalation channel 601 will be mixed with the smoke and inhaled by the user at the air inhalation hole 621. The buffer plug 800 opens the guide channel at the first station 11 to connect the accommodating chamber 911 with the air inhalation channel 601 through the functional channel 740, and the buffer plug 800 blocks the guide channel at the second station 12, so that the accommodating chamber 911 cannot be connected to the air inhalation channel 601 through the functional channel 740.

[0076] See also Fig.19 and Fig.21 , the guide channel can be a plurality of grooves 744 opened on the side wall of the large hole 742, the plurality of grooves 744 are evenly spaced along the circumference of the large hole 742, the grooves 744 extend along the axial direction of the large hole 742 to a set length, that is, the grooves 744 are vertically arranged, and the upper ends of the grooves 744 can extend to the top wall 742a of the large hole 742. When the buffer plug 800 is located at the first station 11, the external gas passing through the air inlet channel 120 can enter the small hole 741 from the grooves 744, so as to enter the air intake hole 621 through the air intake channel 601 and be sucked by the user. At this time, the conduction effect of the grooves 744 on the gas can make it impossible for the buffer plug 800 to block the entire functional channel 740, that is, the buffer plug 800 opens the functional channel 740. Refer to Fig. 20 When the buffer plug 800 is located at the second station 12, the upper end of the buffer plug 800 abuts against the top wall 742a of the large hole 742 to form a sealing effect, and the external gas passing through the air inlet channel 120 can no longer enter the small hole 741 and the air intake channel 601 through the groove 744. At this time, the functional channel 740 will lose the function of conducting gas, that is, the buffer plug 800 blocks the entire functional channel 740. Of course, the guide channel can be a groove opened on the buffer plug 800, and the structure of the groove can be the same as the structure of the groove 744 on the side wall of the large hole 742. In other examples, the guide channel is arranged inside the buffer plug 800, and the guide channel is a through hole that passes through the two end faces of the buffer plug 800, and the axial projection of the through hole is located outside the outline of the small hole 741. When the buffer plug 800 abuts against the top wall 742a of the large hole 742, the top wall 742a will close the through hole of the buffer plug 800, thereby blocking the guide channel.

[0077] When the battery 21 works normally, the difference between the air pressure in the accommodating chamber 911 and the air pressure in the suction channel 601 is less than the threshold pressure. Under the action of friction, the buffer plug 800 is in the first position 11 and the functional channel 740 is open, and the user can inhale smoke from the suction nozzle 620. When the battery 21 explodes under extreme conditions, the difference between the air pressure in the accommodating chamber 911 and the air pressure in the air inhalation channel 601 is greater than the threshold pressure. Under the impact of the explosion, the buffer plug 800 will overcome the friction and move upward at the first station 11. Due to the limiting effect of the top wall 742a of the large hole 742, the buffer plug 800 abuts against the top wall 742a of the large hole 742 and stops moving. At this time, the buffer plug 800 is in the second station 12 and blocks the functional channel 740. The high-temperature gas and harmful substances generated by the explosion of the battery 21 will not be able to enter the air inhalation channel 601 from the accommodating chamber 911 through the functional channel 740, thereby preventing them from being inhaled by the user, thereby improving the safety performance of the entire electronic atomization device 20. The threshold pressure can range from 1KPa to 2MPa, and its specific value can be 1KPa, 2KPa, 1.5MPa or 2MPa. The threshold pressure may also range from 2 KPa to 2 MPa, or from 10 KPa to 1 MPa.

[0078] Therefore, at the first station 11, since the buffer plug 800 forms an interference fit relationship with the large hole 742, there is sufficient static friction between the buffer plug 800 and the large hole 742. When the battery 21 is normal, the buffer plug 800 will be fixed to the first station 11 under the action of the static friction. When the battery 21 explodes, under the action of the explosion impact force, the buffer plug 800 will overcome the static friction and move from the first station 11 to the second station 12, thereby blocking the functional channel 740.

[0079] See also Fig.23 and Fig.24In some examples, a conical hole 743 may also be provided on the base assembly 720, and the conical hole 743 becomes a part of the functional channel 740. The conical hole 743 is located between the large hole 742 and the small hole 741. For example, the upper end (small head end) of the conical hole 743 is connected to the small hole 741, and the lower end (large head end) of the conical hole 743 is connected to the large hole 742, so that the conical hole 743 is connected to the large hole 742 and the small hole 741 at the same time. At the same time, the buffer plug 800 also includes a second sealing portion 820 connected to the first sealing portion 810. The shape of the second sealing portion 820 is roughly conical and adapted to the shape of the tapered hole 743. Under the action of the explosion impact force of the battery 21, while the first sealing portion 810 abuts against the top wall 742a of the large hole 742, the second sealing portion 820 will form a certain interference fit with the tapered hole 743. At this time, the first sealing portion 810 abuts against the top wall 742a of the large hole 742 to form a first seal for the functional channel 740, and the second sealing portion 820 will cooperate with the tapered hole 743 to form a second seal for the functional channel 740, that is, the buffer plug 800 forms a double seal on the functional channel 740, further strengthening the sealing effect of the buffer belt on the functional channel 740, more effectively preventing high-temperature gas and harmful substances from entering the air inlet channel 601 from the functional channel 740, and further improving the safety performance of the electronic atomization device 20.

[0080] See also Fig.16 In some examples, the atomizer assembly 710 may further include a stopper 730, which may be connected to the end of the mounting portion 722 of the base assembly 720, that is, the stopper 730 is located below the mounting portion 722 and above the battery 21, so that the stopper 730 is arranged opposite to the battery 21, and the positive projection of the stopper 730 on the mounting portion 722 covers the entire functional channel 740. Therefore, through the blocking effect of the stopper 730, the liquid leaked from the functional channel 740 will stay on the stopper 730, preventing the leaked liquid from entering the battery 21 and causing damage to the battery 21.

[0081] See also Fig.25 Of course, the air inlet channel 120 of the second example electronic atomization device provided in this other embodiment is opened on the atomizer 700, and the other structures of the second example electronic atomization device are the same as those of the first example electronic atomization device 10. Therefore, when the air inhalation channel 601 is inhaled, the external gas does not need to enter the air inhalation channel 601 from the air inlet channel 120 through the accommodating cavity 911 and the functional channel 740, but directly enters the air inhalation channel 601 from the air inlet channel 120 on the atomizer 700. Or the air inlet channel 120 can also be compared to Fig.25The position shown is closer to the power supply assembly 900 and is located below the buffer plug 800. In this case, when the air intake channel 601 is sucked, the external gas enters from the air intake channel 120, passes through the functional channel 740 first, and then enters the air intake channel 601.

[0082] The present invention also provides an atomizer, the atomizer comprising: Figures 15 to 24 The housing assembly 600, the atomizing assembly 710, the base assembly 720 and the buffer plug 800 in the electronic atomizing device shown in the figure. When the air inhalation channel 601 is sucked, the external gas enters the air inhalation channel 601 from the air inlet channel 120 through the functional channel 740. Of course, it can also be as follows Fig.25 As shown in FIG. 7 , the air inlet channel 120 is opened on the atomizer 700 , and the external gas directly enters the air inlet channel 601 from the air inlet channel 120 .

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
