[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present application.

[0045] An embodiment of the present application provides an electronic atomization device 1. Refer to Figure 1 and Figure 2 , the electronic atomization device 1 includes an atomizer 100 and a power supply assembly 200. The power supply assembly 200 provides power supply for the atomizer 100, and the atomizer 100 atomizes the liquid matrix stored therein to generate aerosol.

[0046] A detachable connection structure is provided between the atomizer 100 and the power supply component 200, and the detachable connection structure can be a magnetic connection or a snap connection in the prior art. In an embodiment provided in the present application, the power supply component 200 serves as a main unit and can be used in combination with different atomizers 100. Different atomizers refer to those with different liquid matrices stored inside, or the atomizer is a consumable, and the liquid matrix stored inside the atomizer cannot be replenished. Different atomizers refer to old atomizers and new atomizers. When the liquid matrix inside the old atomizer is consumed, the liquid matrix can be replenished by replacing the new atomizer.

[0047] Further referring to Figure 2 , the power supply component 200 includes components such as a housing 91, a battery 92, a main body bracket 93, a control component 94, an air flow induction switch 95, and a decorative part 96.

[0048] The inner cavity of the housing 91 is provided as a battery cavity and an atomizer receiving cavity. The battery 92 is received inside the battery cavity. One end of the atomizer receiving cavity is open, and a part of the atomizer can be received inside the atomizer receiving cavity.

[0049] The battery 92 can be a rechargeable battery or a non-rechargeable battery. In the detachable electronic atomization device 1, the battery 92 is preferably provided as a rechargeable battery.

[0050] The main body bracket 93 includes a plurality of partition plates for partitioning the internal space of the housing 91, so that the battery 92, the control component 94, and the air flow induction switch 95 can be separately fixed inside the inner cavity of the housing 91.

[0051] The control component 94 includes a control board and electrical components connected to the control board. The electrical components on the control component 94 can be customized according to the functions of the electronic atomization device 1.

[0052] The air flow induction switch 95 is fixed inside the housing 91 by means of an air flow induction switch seal 951. During the process of the user sucking the electronic atomization device 1, the sensing side of the air flow induction switch 95 senses the negative pressure formed inside the electronic atomization device 1, thereby controlling the power supply component 200 to supply power to the atomizer 100.

[0053] The decorative part 96 is connected to the housing 91 and exposed outside the housing 91, thereby enhancing the overall design aesthetic of the electronic atomization device 1.

[0054] The power supply component 200 further includes a button 961 provided on the housing 91. The button 961 is used to control the opening and closing of the electronic atomization device 1, or the button 961 can also be used to adjust the heating power of the atomizer 100.

[0055] Further referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 ,the atomizer 100 includes a housing 10, a mouthpiece 11, an atomization assembly 20, a sealing element 26, a magnetic element, and an electrode post 83.

[0056] The housing 10 includes a liquid storage cup 12. A part of the inner cavity of the liquid storage cup 12 is configured as a liquid storage chamber 120 for storing a liquid matrix. One end of the liquid storage cup 12 is provided with a mouthpiece 11, and the other end of the liquid storage cup 12 is open, which is conducive to placing the atomization assembly 20 and the sealing element 26 in the inner cavity of the housing 10.

[0057] The housing 10 further includes a base 30, and the base 30 is connected to the open end of the liquid storage cup 12.

[0058] The mouthpiece 11 is connected to one end of the housing 10. The mouthpiece 11 has a hollow mouthpiece opening 111, and the aerosol generated inside the atomizer 100 escapes through the mouthpiece opening 111. During the use of the electronic atomization device 1 by the user, the user's mouth mainly contacts the mouthpiece 11. In a preferred embodiment, the housing 10 and the mouthpiece 11 are separately formed, which is conducive to the mouthpiece 11 being made of a food-grade material. Specifically, an opening is provided at one end of the housing 10, and an inner tube communicating with the opening is provided inside the housing 10. The mouthpiece 11 is inserted into the inner tube through the opening, and a plurality of mouthpiece seals 112 are provided between the mouthpiece 11 and the inner tube. The plurality of mouthpiece seals 112 are used to seal the connection gap between the mouthpiece 11 and the housing 10. In other alternative examples, the mouthpiece 11 and the housing 10 may be integrally formed.

[0059] The atomization assembly 20 includes a liquid guiding element 21 and a heating element 22 combined on the liquid guiding element 21. The liquid matrix stored inside the liquid storage chamber 120 can flow to the liquid guiding element 21 and be provided to the heating element 22 through the liquid guiding element 21. Depending on the material used for the liquid guiding element 21, the liquid guiding element 21 includes a cotton core atomization assembly 20 or a ceramic core atomization assembly 20.

[0060] Further referring to Figure 2 and Figure 4 ,in some embodiments provided by the present application, the atomization assembly 20 is configured as a cotton core atomization assembly. The atomization assembly 20 includes a liquid guiding element 21, a heating element 22, an atomization bracket 23, a sleeve 24, and a sealing seat 25.

[0061] The liquid guiding element 21 includes an inner liquid guiding cotton 211 and an outer liquid guiding cotton 212. The inner liquid guiding cotton 211 is fixed outside the heating element 22, and the outer liquid guiding cotton 212 is fixed outside the inner liquid guiding cotton 211. The liquid matrix inside the liquid storage cavity 120 is preferentially supplied to the outer liquid guiding cotton 212 and then supplied to the inner liquid guiding cotton 211 through the outer liquid guiding cotton 212.

[0062] The heating element 22 is made of heat-generating metal materials such as iron-chromium, nickel-chromium, titanium, 316L stainless steel, palladium-silver, tungsten alloy, etc. The heating element 22 is arranged as a sheet with a grid structure. After being wound, the heating element 22 is fixed inside the inner cavity of the inner liquid guiding cotton 211.

[0063] Both the atomization support 23 and the sleeve 24 are provided with hollow inner cavities. The sleeve 24 is sleeved outside the atomization support 23 and abuts against the outer flange of the atomization support 23. After the heating element 22 is fixed inside the inner liquid guiding cotton 211, it is placed inside the inner cavity of the atomization support 23. The bottom of the inner liquid guiding cotton 211 abuts against the inner flange of the atomization support 23, and the outer liquid guiding cotton 212 is fixed between the atomization support 23 and the sleeve 24. A plurality of first liquid guiding holes are provided on the sleeve 24, and a plurality of second liquid guiding holes are also provided on the atomization support 23. The liquid matrix inside the liquid storage cavity 120 is supplied to the outer liquid guiding cotton 212 through the plurality of first liquid guiding holes. The liquid matrix stored in the outer liquid guiding cotton 212 is supplied to the inner liquid guiding cotton 211 through the plurality of second liquid guiding holes and then supplied to the heating element 22 through the inner liquid guiding cotton 211.

[0064] The sealing seat 25 is connected to the bottom opening of the atomization support 23. Two wires are respectively connected to both sides of the heating element 22. The two wires are arranged through the sealing seat 25 and connected to the electrode posts 83 of the atomizer 100.

[0065] The atomizer 100 is further provided with an atomization airway 70. The atomization airway 70 includes an air inlet section and an air outlet section. Air enters through the air inlet section, and the aerosol generated by atomizing the atomization assembly 20 is mixed with the air and escapes through the air outlet section. The air inlet section of the atomization airway 70 is defined by the inner cavity of the atomization support 23, and the air outlet section of the atomization airway 70 is defined by the inner cavity of the sleeve 24. One end of the sleeve 24 away from the atomization support 23 is connected to the inner tube of the housing 10 and is communicated with the suction nozzle 111.

[0066] The atomizer 100 further includes a sealing element 26. The sealing element 26 is preferably made of flexible silicone material. The sealing element 26 is connected between the outer surface of the atomization assembly 20 and the inner surface of the housing 10. The sealing element 26 is located below the first liquid guiding holes on the sleeve 24. The sealing element 26 includes a fixing hole, and the bottom of the atomization assembly 20 is received in the fixing hole. A part of the base 30 is embedded in the sealing element 26 to enhance the structural strength of the sealing element 26.

[0067] The atomizer 100 further includes a liquid absorption element 80. The liquid absorption element 80 is disposed in the inner cavity of the base 30. The liquid absorption element 80 is made of fiber cotton material. The liquid absorption element 80 is disposed below the atomization airway 70 and is used to absorb the condensate flowing out from the end of the atomization airway 70.

[0068] The atomizer 100 further includes a magnetic element. The atomizer 100 is magnetically connected to a magnetic attraction element disposed inside the power supply assembly 200 through the magnetic element. In an embodiment provided by the present application, the magnetic element includes a first magnetic element 81 and a second magnetic element 82. The first magnetic element 81 is connected to the base 30 and is disposed close to one side of the base 30. The second magnetic element 82 is connected to the base 30 and is disposed close to the other side of the base 30. The first magnetic element 81 includes two cylindrical magnets. The two cylindrical magnets are spaced apart, and the spacing direction of the two cylindrical magnets is perpendicular to the spacing direction of the first magnetic element 81 and the second magnetic element 82. The second magnetic element 82 includes a magnet. The cross section of the magnet is set as a racetrack shape, and the cross-sectional area of the second magnetic element 82 is larger than the cross-sectional area of any one of the first magnetic elements 81. By providing the first magnetic element 81 and the second magnetic element 82 with different shapes on the atomizer 100, it is beneficial to improve the stability of the magnetic attraction connection between the atomizer 100 and the power supply assembly 200.

[0069] The atomizer 100 further includes two electrode posts 83. One ends of the two electrode posts 83 are electrically connected to the heating element 22 through wires, and the other ends of the two electrode posts 83 are electrically connected to the electrode posts inside the power supply assembly 200. The two electrode posts 83 are disposed close to the second magnetic element 82, and the spacing direction of the two electrode posts 83 is the same as the spacing direction of the two first magnetic elements 81. Since the magnetic attraction area of the second magnetic element 82 is relatively large, it is beneficial for the two electrode posts 83 of the atomizer 100 to maintain stable contact with the electrode posts inside the power supply assembly 200 and conduct electricity.

[0070] In the related art, the air inlet of the electronic atomization device is usually disposed on the power supply assembly. A communication airway is provided between the power supply assembly and the atomizer. After the air enters through the air inlet, it enters the atomizer through the communication airway between the power supply assembly and the atomizer. The air inlet cross-sectional area of the communication airway is limited, which leads to a relatively large airflow sound when the airflow enters the atomizer, thereby affecting the suction experience of the user.

[0071] In the embodiment of the present application, by improving the air inlet structure of the electronic atomization device, the airflow sound generated during the suction process of the electronic atomization device is effectively reduced.

[0072] Such as Figures 1 to 3As shown, a first notch 98 is formed at the connection between the housing 10 of the atomizer 100 and the outer housing 91 of the power supply assembly 200. The first notch 98 is used for allowing external air to enter. The atomizer 100 is provided with a second connection end 130, and the power supply assembly 200 is provided with a first connection end 210. The first connection end 210 is connected to the second connection end 130. An air guide cavity 99 is also formed between the second connection end 130 and the first connection end 210. The air guide cavity 99 is communicated with the first notch 98. The air inlet of the atomizer 100 includes the first notch 98 and the air guide cavity 99. External air flow enters the air guide cavity 99 through the first notch 98 and is then supplied to the atomizer 100.

[0073] Compared with providing a communication air passage between the power supply assembly and the atomizer, in the embodiments of the present application, through the communication structure of the first notch 98 and the air guide cavity 99 provided at the connection between the atomizer and the power supply assembly, air enters the air guide cavity 99 from the first notch 98 to form a process of air flow diffusion. Therefore, the air flow sound can be effectively weakened.

[0074] Continue to refer to Figure 1 Figure 3 、 Figure 5 and Figure 6 , the housing 10 of the atomizer 100 includes a liquid storage cup 12 and a base 30 connected to the open end of the liquid storage cup 12. The second connection end 130 is configured to be defined by the bottom end surface of the base 30. The power supply assembly 200 includes an outer housing 91 and a main body bracket 93 received inside the outer housing 91. The top end surface of the main body bracket 93 defines the first connection end 210. A first groove 34 is provided on either the bottom end surface of the base 30 or the top end surface of the main body bracket 93. The first groove 34 defines the air guide cavity 99. The first groove 34 is communicated with the first notch 98. In a preferred embodiment, the first groove 34 is provided with a flared inlet, and the inlet of the first groove 34 is communicated with the first notch 98.

[0075] External air enters the air guiding cavity 99 through the first notch 98 at the connection between the atomizer 100 and the power supply assembly 200. Since the entrance of the first groove 34 where the air guiding cavity 99 is located is set in a flared shape, it is conducive to the convergence of air at the air inlet of the atomizer 100 and then enters the internal air flow channel of the atomizer 100. An air flow diffusion process is formed at the air inlet of the atomizer 100 for the external air, so that the air flow sound generated when the external air enters the atomizer 100 during the suction process can be effectively reduced. It can be understood that setting the entrance of the first groove 34 where the air guiding cavity 99 is located in a flared shape is conducive to converging the external air into the air guiding cavity 99, thus making the flow of the external air smoother. By designing a reasonable flared entrance shape, the turbulence and vibration generated when the external air enters the opening of the atomizer 100 can be reduced, so that the air flow can be adjusted and smoothed after entering the inside of the air guiding cavity 99, and further the friction and collision between the air flow and the wall where the air inlet of the atomizer 100 is located can be reduced, thereby reducing the generation of noise.

[0076] Continue to refer to Figure 5 , the first notch 98 is provided on the side surface of the housing 10, so that a height difference is formed between the top surface where the air inlet of the atomizer 100 is located and the second connection end 130.

[0077] By arranging the top surface where the air inlet of the atomizer 100 is located on the side wall of the housing 10, the path for the external air to enter the air inlet of the atomizer 100 is made smoother. Further, raising the position of the air inlet of the atomizer 100 can prevent the condensate or liquid matrix from overflowing or being exposed from the air inlet of the atomizer 100.

[0078] Continue to refer to Figures 2 to 5 , the base 30 further includes an air guiding part 31. The air guiding part 31 is provided with a first air inlet channel 51. One end of the first air inlet channel 51 is communicated with the air guiding cavity 99, and the other end of the first air inlet channel 51 is communicated with the inner cavity of the base 30.

[0079] As Figure 2 and Figure 3 The arrow shown in indicates the air flow path for the external air to enter the atomizer 100. The external air sequentially enters the first air inlet channel 51 inside the atomizer 100 through the first notch 98 and the air guiding cavity 99. The extending direction of the first air inlet channel 51 is different from the extending direction of the first groove 34 where the air guiding cavity 99 is located, so that a tortuous air flow path is formed inside the atomizer 100, thereby making it difficult for the liquid matrix or condensate to leak to the outside through the first air inlet channel 51.

[0080] The air guiding part 31 is set as a convex column structure longitudinally extending in the inner cavity of the base 30, and the first air inlet channel 51 can be a through hole provided on the air guiding part 31.

[0081] Continue to refer Figure 2 , Figure 3 and Figure 5 The inner cavity of the atomizing bracket 23 defines a portion of the atomizing airway 70, the inlet of the atomizing airway 70 is configured to allow air to enter, and the outlet of the atomizing airway 70 is configured to allow aerosol to escape. In the embodiment provided in the present application, the atomizing airway 70 is staggered with the first air inlet channel 51, the first air inlet channel 51 is connected to the atomizing airway 70 through the inner cavity of the base 30, and the top end surface of the first air inlet channel 51 is higher than the bottom end surface of the atomizing airway 70.

[0082] like Figure 2 , Figure 3 and Figure 5 The arrows show the airflow path of external air entering the air inlet channel 50 of the atomizer 100. The external air enters the first air inlet channel 51 inside the atomizer 100 through the first notch 98 and the air guide cavity 99, and enters the atomizing air channel 70 through the inner cavity of the base 30. Since the atomizing air channel 70 is staggered with the first air inlet channel 51, and the top end surface of the air guide portion 31 defining the first air inlet channel 51 is higher than the bottom end surface of the atomizing bracket 23, the condensate flowing out through the atomizing bracket 23 is further stored in the inner cavity of the base 30.

[0083] The top end surface where the first air inlet channel 51 is located is configured as the top where the air guide portion 31 is located, and the bottom end surface where the atomizing air channel 70 is located is configured as the bottom end surface of the atomizing bracket 23 or the bottom end surface of the sealing seat 25. When the amount of condensate stored is large, since the bottom end surface where the atomizing air channel 70 is located is lower than the top end surface of the first air inlet channel 51, the condensate can be prevented from further overflowing, thereby effectively preventing the condensate from leaking to the outside through the first air inlet channel 51.

[0084] Continue to refer Figure 3 and Figure 5 The liquid absorption element 80 is disposed in the inner cavity of the base 30 and is located on one side of the air guide portion 31 .

[0085] By arranging a liquid absorption element 80 in the inner cavity of the base 30, the liquid absorption element 80 is located below the atomizing bracket 23 and on one side of the air guide portion 31, the condensed liquid flowing out from the atomizing airway 70 can be further stored in the liquid absorption element 80, further improving the anti-leakage capability of the atomizer 100.

[0086] Continue to refer Figure 2 and Figure 3, an induction air passage 60 communicating with the induction side of the air flow induction switch 95 is further provided in the electronic atomization device 1. The induction air passage 60 includes a first induction air passage 61 disposed inside the atomizer 100 and a second induction air passage 62 disposed inside the power supply assembly 200. One end of the first induction air passage 61 communicates with one end of the second induction air passage 62. During the process of a user sucking the electronic atomization device 1, a negative pressure will be formed in the first induction air passage 61. After the induction end of the air flow induction switch 95 senses that the negative pressure reaches a certain threshold, the electronic atomization device 1 is turned on.

[0087] The first induction air passage 61 is usually combined with the first air intake passage 51 into one passage. When the air intake volume of the first air intake passage 51 is set to be adjustable, for example, when the air intake volume of the atomizer 100 is set to be large, correspondingly, the air flow volume of the induction air passage 60 communicating with the air flow induction switch 95 is also large, which will cause the induction side and the normal pressure side of the air flow induction switch 95 to not form a sufficient pressure difference, resulting in the air flow induction switch 95 not being triggered, thus affecting the normal use of the electronic atomization device 1.

[0088] The first air intake passage 51 is provided with a first air intake port 511 and a first air outlet port 512. The first air intake port 511 communicates with the air guide cavity 99, and the first air outlet port 512 communicates with the inner cavity of the base 30.

[0089] The first induction air passage 61 is provided with a second air intake port 611 and a second air outlet port 612. The second air intake port 611 is configured to communicate with the second induction air passage 62, and the second air outlet port 612 communicates with the first air outlet port 512 and is connected to the air intake end of the atomization air passage 70.

[0090] In some embodiments of the present application, the structure inside the atomizer 100 is optimized, so that the air intake volume of the air intake passage 50 of the atomizer 100 does not interfere with the air flow volume of the first induction air passage 61. Thus, during the process of adjusting the air flow of the atomizer 100, the air flow induction switch 95 can work normally.

[0091] Reference Figure 2 、 Figure 4 、 Figure 5 、 Figures 7 to 10 , the atomizer 100 further includes an air flow adjusting assembly 40, and the air flow adjusting assembly 40 is connected to the base 30. The air flow adjusting assembly 40 includes an air flow adjusting member 41 and an air flow adjusting cover 42 connected to the top end of the air flow adjusting member 41.

[0092] A through hole 311 is provided inside the air guiding part 31. The air regulating member 41 is accommodated in the through hole 311 of the air guiding part 31. A first air guiding interval 312 is formed between the outer surface of the air regulating member 41 and the inner surface of the air guiding part 31. A first air outlet 512 is provided at the top end of the air guiding part 31. The first air guiding interval 312 and the first air outlet 512 define a first air inlet passage 51. The air regulating member 41 is further provided with a through hole 44, and the through hole 44 defines a first induction air passage 61. The first induction air passage 61 is closer to the atomizing assembly 20 than the first air inlet passage 51.

[0093] By separating the first induction air passage 61 and the first air inlet passage 51, the interference caused by the change in the air flow rate inside the first air inlet passage 51 to the first induction air passage 61 is effectively reduced. Further, by setting the second air outlet 612 of the first induction air passage 61 to be closer to the atomizing assembly 20 than the first air outlet 512 of the first air inlet passage 51, that is, closer to the air inlet end of the atomizing air passage 70, when the user is sucking, negative pressure is successively formed at the suction nozzle 111 and in the atomizing air passage 70. Since the second air outlet 612 of the first induction air passage 61 is set closer to the air inlet end of the atomizing air passage 70 than the first air outlet 512 of the first air inlet passage 51, negative pressure will be preferentially formed inside the induction air passage 60 compared to the inside of the air inlet passage 50, improving the sensitivity of the air flow induction switch 95.

[0094] Continue to refer to Figure 10 , the air regulating member 41 is fixed on the air guiding part 31 of the base 30, and the top of the air regulating member 41 abuts against the sealing element 26, so that the air regulating assembly 40 can be stably accommodated inside the housing 10.

[0095] Continue to refer to Figure 4 、 Figure 5 and Figure 10 , the through hole 44 extends along the central axis of the air regulating assembly 40. The through hole 44 includes a first through hole passing through the air regulating member 41 and a second through hole provided at the center of the air regulating cover 42. The second air inlet 611 is located at the bottom of the air regulating member 41, and the second air outlet 612 is located above the air regulating cover 42. During the rotation of the air regulating assembly 40 relative to the base 30, the cross-sectional areas of the second air inlet 611 and the second air outlet 612 remain unchanged. Therefore, even if the atomizer 100 is set to the fully open state and external air flows into the air inlet passage 50, and the induction air passage 60 is arranged close to the atomizing air passage 70, the negative pressure generated inside the atomizing air passage 70 will preferentially extend into the induction air passage 60, and thus will not affect the normal operation of the air flow induction switch 95.

[0096] Refer to Figure 5, along the width direction or the thickness direction of the housing 10 of the atomizer 100, the atomization airway 70, the first induction airway 61, and the first air intake passage 51 are sequentially arranged at intervals.

[0097] By arranging the first air intake passage 51 and the first induction airway 61 of the atomizer 100 at intervals, during the process of the air volume adjusting assembly 40 adjusting the air volume of the first air intake passage 51, the air volume inside the first induction airway 61 will not change, and thus will not interfere with the normal operation of the air flow induction switch 95.

[0098] Furthermore, by arranging the atomization airway 70 and the first induction airway 61 at intervals, the condensate flowing out through the atomization airway 70 is difficult to enter the first induction airway 61, thereby preventing the condensate from flowing into the air flow induction switch 95 through the first induction airway 61 and corroding the air flow induction switch 95.

[0099] In the embodiment provided by the present application, the atomizer 100 is arranged in a box shape, and the width direction of the housing 10 is as Figure 5 shown by the arrow Y in the figure, wherein the atomization airway 70 is configured to extend basically along the height direction of the housing 10, the first air intake passage 51 is configured to extend basically along the height direction of the housing 10, the first induction airway 61 arranged on the atomizer 100 is configured to extend basically along the height direction of the housing 10, and the height direction of the housing 10 is as Figure 5 shown by the arrow X in the figure.

[0100] As Figure 2 , Figure 3 and Figure 5 shown in the figure, the air flow directions of the first induction airway 61, the air intake passage 50, and the atomization airway 70 inside the electronic atomization device 1 are marked, wherein the top end surface where the first air outlet 512 of the first air intake passage 51 is located is lower than the top end surface where the second air outlet 612 of the first induction airway 61 is located.

[0101] It can be understood that if there is a relatively large amount of condensate stored in the inner cavity of the base 30, since the top end surface where the first air outlet 512 of the first air intake passage 51 is located is lower than the top end surface where the second air outlet 612 of the first induction airway 61 is located, the condensate will overflow from the first air outlet 512 first, further preventing the condensate from entering the induction airway 60, and thus preventing the air flow induction switch 95 from being corroded by the condensate.

[0102] The air regulating member 41 is disposed at the bottom of the base 30, that is, at the bottom of the atomizer 100. When the user does not use the electronic atomization device 1, a part of the atomizer 100 is received in the atomizer 100 receiving cavity of the power supply assembly 200. A child needs to separate the atomizer 100 from the power supply assembly 200 before being able to operate the air regulating assembly 40, thereby enabling the above-mentioned air regulating assembly 40 to function as a child lock.

[0103] In some embodiments, the air regulating member 41 is configured as a rotary switch. By rotating the rotation angle of the air regulating member 41, the cross-sectional area of the first air outlet 512 is adjusted, which is simple and convenient to operate.

[0104] In other alternative examples, the air regulating member 41 can also be configured as a sliding switch. The sliding switch can be further configured to slide along the width direction or the height direction of the housing 10 to adjust the cross-sectional area of the first air outlet 512.

[0105] Further referring Figure 4 and Figure 6 , the air regulating member 41 includes a main body portion 413 and an operating portion 411 disposed at one end of the main body portion 413. The operating portion 411 protrudes relative to the bottom end surface of the base 30, facilitating the user to operate the air regulating member 41. The operating portion 411 includes a first operating protrusion and a second operating protrusion disposed at intervals. The user drives the air regulating member 41 to rotate by applying a force to the first operating protrusion and the second operating protrusion. A flange 414 is further disposed on the main body portion 413 of the air regulating member 41, and a convex table surface is disposed on the inner surface of the air guiding portion 31. The flange 414 of the air regulating member 41 abuts against the convex table surface of the air guiding portion 31.

[0106] A plurality of air regulating member seals 43 are further sleeved on the outer surface of the main body portion 413. The plurality of air regulating member seals 43 are used to seal the connection gap between the air regulating member 41 and the air guiding portion 31 of the base 30. The plurality of air regulating member seals 43 are located above the flange 414 of the air regulating member 41, further enhancing the sealing performance of the atomizer 100.

[0107] The air regulating member 41 is configured to be rotatable relative to the base 30. The air regulating member 41 drives the air regulating cover 42 to rotate or move, thereby changing the relative position between the air regulating cover 42 and the first air outlet 512 to adjust the airflow flowing out through the first air inlet passage 51. In a specific embodiment, the air regulating member 41 is configured to be rotatable relative to the base 30, thereby driving the air regulating cover 42. The air regulating cover 42 is disposed at the top end surface where the first air outlet 512 is located. During the rotation of the air regulating cover 42, the cross-sectional area of the first air outlet 512 not blocked by the air regulating cover 42 changes, thereby adjusting the airflow flowing out through the first air inlet passage 51.

[0108] It is understandable that, compared with setting the air regulating cover 42 at the first air inlet 511 of the air inlet passage 50, that is, at least a part of the air regulating cover 42 is exposed on the bottom end surface of the base 30, the air regulating cover 42 is prone to misoperation when the electronic atomization device is shaken by an external force. In the embodiments of the present application, the air regulating cover 42 is installed in the inner cavity of the base 30, and the air regulating cover 42 is driven by the air regulating member 41 to rotate to adjust the cross-sectional area of the first air outlet 512, which can effectively avoid misoperation.

[0109] In some embodiments provided by the present application, the cross-section of the first air outlet 512 provided on the air guiding portion 31 of the base 30 is set to be fan-shaped, the air regulating cover 42 is provided with a second notch 421, the cross-sectional area of the second notch 421 is not less than the cross-sectional area of the first air outlet 512, the atomizer 100 has an open state and a closed state. When the atomizer 100 is in the open state, the first air outlet 512 is configured to be completely staggered from the air regulating cover 42, and the suction resistance of the atomizer 100 is the smallest, as Figures 7 to 10 shown. When the atomizer 100 is in the closed state, the first air outlet 512 is configured to be completely blocked by the air regulating cover 42, and the atomizer 100 cannot work properly, as Figures 11 to 15 shown.

[0110] Continuing to refer to Figures 7 to 10 , when the atomizer 100 is in the open state, the connection line between the two operation protrusions of the air regulating member 41 is arranged at an angle with the width direction of the housing 10.

[0111] Continuing to refer to Figures 11 to 15 , when the atomizer 100 is in the closed state, the connection line between the two operation protrusions of the air regulating member 41 coincides with the width direction of the housing 10. By judging the position state of the two operation protrusions, it can be known whether the air regulating member 41 rotates in place.

[0112] Referring to Figures 7 to 10 and Figures 16 to 19 , the open state of the atomizer 100 includes a first open state and a second open state, and the suction resistance in the first open state is less than the suction resistance in the second open state. When the atomizer 100 is in the first open state, as Figures 7 to 10 shown, the first air outlet 512 is completely staggered from the air regulating cover 42, the cross-sectional area of the first air outlet 512 is in the maximum state, correspondingly, the air intake volume of the air inlet passage 50 is in the maximum state, and the suction resistance of the atomizer 100 is the smallest; when the atomizer 100 is in the second open state, as Figures 16 to 19 shown, at least a part of the first air outlet 512 is staggered from the air regulating cover 42. For example, when the atomizer 100 is in a semi-open state, the cross-sectional area of the first air outlet 512 staggered from the air regulating cover 42 occupies half of the total cross-sectional area of the first air outlet 512.

[0113] Further referring to Figures 7 to 10 , when the atomizer 100 is in the fully open state, the connection line between the two operating protrusions of the air regulating member 41 coincides with the thickness direction of the housing 10, where the thickness direction of the housing 10 is as shown by the arrow Z in Figure 9 . By judging the position state of the two operating protrusions, it can be further known whether the air regulating member 41 rotates in place.

[0114] Further referring to Figures 16 to 19 , when the atomizer 100 is in the partially open state, the connection line between the two operating protrusions of the air regulating member 41 is arranged at an angle with the width direction or the thickness direction of the housing 10. By judging the position state of the two operating protrusions, it can be further known whether the air regulating member 41 rotates in place.

[0115] It can be understood that the relative position state between the two operating protrusions of the air regulating member 41 and the housing 10 can be adjusted according to design requirements. For example, when the atomizer 100 is in the closed state, the connection line between the two operating protrusions can be set to be parallel to the thickness direction of the housing 10, and when the atomizer 100 is in the fully open state, the connection line between the two operating protrusions can be set to be parallel to the width direction of the housing 10.

[0116] In other alternative examples, a plurality of spaced first air outlets 512 are provided on the air guiding portion 31 of the base 30, and the relative position state between the air regulating cover 42 and the plurality of first air outlets 512 is controlled by rotating the air regulating assembly 40. For example, when the atomizer 100 is in the closed state, the air regulating cover 42 completely blocks the plurality of first air outlets 512; when the atomizer 100 is in the fully open state, the air regulating cover 42 is completely staggered from the plurality of first air outlets 512; when the atomizer 100 is in the partially open state, the air regulating cover 42 blocks a part of the first air outlets 512, and the other part of the first air outlets 512 is staggered from the air regulating cover 42.

[0117] Further in combination with Figure 1 、 Figure 2 and Figure 3As shown in the figure, after the atomizer 100 and the power supply assembly 200 are connected, a notch 98 is formed, and external air can enter the intake passage 50 of the atomizer 100 through the notch 98. The air regulating member 41 is accommodated in the through hole 311 of the air guiding portion 31 of the base 30, and the air regulating member 41 can rotate relative to the air guiding portion 31 of the base 30. A first air guiding interval 312 is formed between the inner surface of the air guiding portion 31 and the outer surface of the air regulating member 41. The first air guiding interval 312 forms a part of the intake passage 50, and the part of the first air guiding interval 312 located on the bottom end surface of the base 30 forms a first air inlet 511. Therefore, during the rotation of the air regulating member 41, the cross-sectional area of the first air inlet 511 remains unchanged, and during the rotation of the air regulating member 41, the air regulating cover 42 is further driven to rotate. During the rotation of the air regulating cover 42, the cross-sectional area of the adjustable first air outlet 512 can be adjusted.

[0118] The above-mentioned structure of the intake passage 50 is arranged such that the intake passage 50 extends substantially along the height direction of the housing 10, making the airflow inside the atomizer 100 flow more smoothly, which is beneficial to reducing the noise generated by the airflow and improving the user experience.

[0119] Reference Figure 6 Referring to, on the bottom end surface of the base 30, a first magnetic element 81, an air regulating member 41, two electrode posts 83, and a second magnetic element 82 are arranged in sequence. The air regulating member 41 is fixed on the base 30. The through hole 44 provided on the air regulating member 41 is located between two operation protrusions, and the first groove 34 that defines the air guiding cavity 99 is located between the two first magnetic elements 81.

[0120] Continue to refer to Figure 10 、 Figure 14 and Figure 19 , at one end of the air regulating member 41 away from the operation portion 411, a first buckle portion 4121 and a second buckle portion 4122 are arranged at intervals. The air regulating cover 42 is snapped onto the air regulating member 41 through the first buckle portion 4121 and the second buckle portion 4122, so that the air regulating cover 42 can be stably connected to the air regulating member 41.

[0121] At one end of the air regulating member 41 away from the operation portion 411, a first convex column 4131 and a second convex column 4132 are further provided. A first interval and a second interval are formed between the first buckle portion 4121 and the second buckle portion 4122. The first convex column 4131 is located in the first interval, the second convex column 4132 is located in the second interval, and the top end surfaces of the first convex column 4131 and the second convex column 4132 are arranged higher than the top end surfaces of the first buckle portion 4121 and the second buckle portion 4122. The top end surfaces of the first convex column 4131 and the second convex column 4132 abut against the sealing element 26.

[0122] Further, second air guiding intervals are formed between the two sides of the first convex post 4131 and the first and second snap portions 4121 and 4122 respectively, and between the two sides of the second convex post 4132 and the first and second snap portions 4121 and 4122 respectively. The second air guiding intervals define the second air outlet 612 of the first induction air passage 61.

[0123] Continue to refer to Figure 2 and Figure 3 , an air guiding post 97 is further provided on the power supply assembly 200. The air guiding post 97 is made of flexible silica gel material. The air guiding post 97 is provided with induction air holes. The end of the induction air holes is communicated with the sensing end of the air flow induction switch 95. The induction air holes define the second induction air passage 62. A part of the top surface of the air guiding post 97 can be inserted into the through hole 44 of the air regulating member 41. The air guiding post 97 seals the bottom of the induction air passage 60 defined by the air regulating member 41, preventing liquid from entering the induction air holes of the power supply assembly 200 through the connection between the atomizer 100 and the power supply assembly 200, and further corroding the air flow induction switch 95.

[0124] In other alternative examples, the air guiding post 97 provided on the power supply assembly 200 and the air regulating member 41 can be integrally provided, further saving the internal space of the electronic atomization device 1.

[0125] As Figure 20 shown by the arrow, the route map of the condensate overflowing from the inside of the atomizer 100 through the atomization air passage 70 to the outside is marked. Since the top surface where the second air outlet 612 of the first induction air passage 61 is located is higher than the top surface where the first air outlet 512 of the first intake passage 51 is located, when there is a large amount of condensate accumulated in the inner cavity of the base 30, for example, the condensate reaches the dotted line position as Figure 20 shown, the condensate preferentially enters the first intake passage 51 through the first air outlet 512, effectively preventing the condensate from entering the first induction air passage 61. Further, the first convex post 4131 and the second convex post 4132, the first snap portion 4121 and the second snap portion 4122 provided at the top of the first induction air passage 61 will further block the condensate from entering the induction air passage 60.

[0126] As shown in Figure 20 , Figure 21 , Figure 22a and Figure 22bAs shown, in some embodiments provided by the present application, the atomizer 100 is configured as a liquid injection structure. At one end of the housing 10, there is a liquid injection hole 14, as well as a sliding cover 131 and a liquid injection hole seal 132 for sealing and opening the liquid injection hole 14. The sliding cover 131 is connected to the liquid injection hole seal 132 to form a sliding cover assembly 13. The sliding cover assembly 13 and the nozzle 11 are located at the same end of the housing 10. By driving the sliding cover assembly 13 to slide away from the nozzle 11, the liquid injection hole 14 can be opened. By driving the sliding cover assembly 13 to slide towards the nozzle 11, the liquid injection hole 14 can be closed.

[0127] A boss portion 133 is provided on the back surface of the sliding cover assembly 13. The boss portion 133 is provided on the liquid injection hole seal 132. The liquid injection hole 14 is configured as a counterbore. The boss portion 133 is configured to be embedded in the liquid injection hole 14 to seal the periphery of the liquid injection hole 14, so that the sliding cover assembly 13 can stably seal the liquid injection hole 14.

[0128] At least a part of the top surface of the housing 10 is recessed inward to form a second groove 15. The second groove 15 extends to the side of the housing 10. The sliding cover assembly 13 is configured to slide within the second groove 15.

[0129] Compared with setting the above-mentioned sliding cover assembly 13 on the front side, rear side, left side and right side of the housing 10, the space where the sliding cover assembly 13 can be installed and slide is limited, which makes it inconvenient for the user to perform the liquid injection operation. By setting the above-mentioned sliding cover assembly 13 on the top surface of the housing 10, the sliding range of the sliding cover assembly 13 is larger and the operation is convenient.

[0130] Reference Figure 22a , a sliding portion 139 is further provided on the sliding cover 131. The sliding portion 139 protrudes relative to the outer surface of the sliding cover 131. In a preferred embodiment, the sliding portion 139 is configured in the form of an operation indication arrow to prompt the user of the operation direction of the sliding cover assembly 13.

[0131] Continuing to refer to Figure 21 , Figure 22a and Figure 22b , a sliding guide groove 134 is further provided inside the second groove 15. The sliding guide groove 134 is located on both sides of the second groove 15. Correspondingly, convex ribs 135 are provided on both sides of the sliding cover 131. The convex ribs 135 are configured to slide within the sliding guide groove 134. In other alternative examples, a sliding guide groove 134 is provided on the sliding cover assembly 13. The sliding guide groove 134 is located on both sides of the sliding cover 131. Correspondingly, convex ribs 135 are provided in the second groove 15 of the housing 10.

[0132] Inside the second groove 15, a limiting groove 136 is further provided. The limiting groove 136 is formed by further recessing the bottom wall where the second groove 15 is located. Correspondingly, on the back surface of the sliding cover assembly 13, a limiting protrusion 137 is provided. The limiting protrusion 137 is configured to slide within the limiting groove 136. The distance that the limiting groove 136 extends along the width direction of the housing 10 is set as the sliding stroke of the sliding cover 131. In other alternative examples, a limiting groove 136 is provided on the sliding cover assembly 13, and a limiting protrusion 137 is provided in the second groove 15 of the housing 10.

[0133] Continue to refer to Figure 22b , on the back surface of the sliding cover assembly 13, a plurality of damping ridges 138 are provided. The plurality of damping ridges 138 are provided on the liquid injection hole seal 132. The plurality of damping ridges 138 are arranged to contact the housing 10, so as to prevent a gap from being formed between the bottom end surface of the sliding cover assembly 13 and the housing 10, which may cause the sliding cover assembly 13 to shake within the second groove 15.

[0134] Refer to Figures 23 to 26 As shown, when the liquid injection hole 14 of the atomizer 100 is in the closed state, one side of the sliding cover assembly 13 abuts against one side wall where the second groove 15 is located. The limiting protrusion 137 provided on the sliding cover 131 abuts against one side wall where the limiting groove 136 is located. The boss portion 133 provided on the liquid injection hole seal 132 forms a stable circumferential seal with the liquid injection hole, thereby preventing the liquid matrix inside the liquid storage cavity from leaking. The top end surface of the ridge 135 provided on the sliding cover 131 abuts against the bottom wall where the sliding guide groove 134 is located. The damping ridges 138 provided on the liquid injection hole seal 132 are in contact with the housing 10, further preventing the sliding cover assembly 13 from shaking within the second groove 15. Through the top limiting effect between the ridge 135 and the sliding guide groove 134 and the bottom limiting effect formed between the damping ridges 138 and the housing 10, the sliding cover assembly 13 can be stably received in the second groove 15 without shaking.

[0135] Refer to Figures 27 to 30 As shown, when the liquid injection hole 14 of the atomizer 100 is in the open state, the boss portion 133 provided on the liquid injection hole seal 132 is completely offset from the liquid injection hole. The boss portion 133 is further received in the limiting groove 136 to avoid interference between the boss portion 133 and the housing 10. The limiting protrusion 137 provided on the sliding cover abuts against the other side wall where the limiting groove 136 is located.
