Description

Technical Field

[0001] This application belongs to the technical field of atomization, and particularly relates to an atomizer and an electronic atomization device. Background Art

[0002] The atomizer is provided with an atomization channel and an air inlet channel. External air flow is supplied to the atomization channel through the air inlet channel for the atomization component to atomize the liquid matrix into aerosol. In the electronic atomization device, there is also an air flow induction switch and an induction air duct connected to the induction side of the air flow induction switch. The part of the induction air duct arranged in the atomizer is usually combined with the air inlet channel into one channel. When the air intake of the air inlet channel is set to be adjustable, for example, when the air intake of the atomizer is set to be large, correspondingly, the air flow rate of the induction air duct connected to the air flow induction switch is also large, which further causes insufficient pressure difference between the induction side and the atmospheric pressure side of the air flow induction switch, resulting in the air flow induction switch not being triggered, and thus affecting the normal use of the electronic atomization device.

The first air inlet is connected to external air flow, and the air adjustment component is configured to be rotatable or movable relative to the base, so as to adjust the cross-sectional area of the first air outlet or the first air inlet;

Further, by arranging the atomization air passage, the induction air passage, and the intake air passage at intervals in the width direction of the atomizer, it is beneficial to prevent the condensate flowing out of the atomization air passage from directly entering the induction air passage, thereby corroding the air flow induction switch.

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.

[0050] 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. The connection structure between the atomizer 100 and the power supply assembly 200 can be set as a non-detachable connection structure, or the connection structure between the atomizer 100 and the power supply assembly 200 can be set as a detachable connection structure. The detachable connection structure can be a magnetic connection or a buckle connection in the prior art.

[0051] Continue to refer to Figure 1 and Figure 2 , in an embodiment provided by the present application, the atomizer 100 and the power supply component 200 are detachably connected. The power supply component 200 serves as the main body and can be combined with different atomizers 100. Different atomizers refer to those with different liquid matrices stored inside or the atomizer being a consumable with the liquid matrix inside not replenishable.

[0052] Further refer to Figure 2 , the power supply component 200 includes components such as a housing 91, a battery 92, a support frame 93, a control component 94, an air flow induction switch 95, and a decorative piece 96.

[0053] 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.

[0054] The support frame 93 includes a plurality of partition plates for partitioning the internal space of the housing 91, so that the battery, the control component 94, and the air flow induction switch 95 can be separately fixed inside the inner cavity of the housing 91.

[0055] 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 set as a rechargeable battery.

[0056] 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.

[0057] 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 on 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.

[0058] The decorative piece 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.

[0059] 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.

[0060] Further reference Figures 2 to 4 As shown, the atomizer 100 includes a housing 10, a mouthpiece 11, an atomization assembly 20, a sealing element 26, a base 30, a magnetic element, and an electrode post 83.

[0061] A part of the inner cavity of the housing 10 is set as a liquid storage cavity 120, and the liquid storage cavity 120 is used to store a liquid matrix. One end of the housing 10 is provided with a mouthpiece 11, and the other end of the housing 10 is open, which is beneficial to placing the atomization assembly 20 and the sealing element 26 in the inner cavity of the housing 10.

[0062] 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 beneficial to preparing the mouthpiece 11 with food-grade materials. 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.

[0063] 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 cavity 120 can flow to the liquid guiding element 21 and be provided to the heating element 22 through the liquid guiding element 21. According to the different materials 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. Further reference Figure 1 , the atomization assembly 20 is set as a cotton core atomization assembly. The liquid guiding element 21 includes an inner layer liquid guiding cotton 211 and an outer layer liquid guiding cotton 212. The inner layer liquid guiding cotton 211 is fixed outside the heating element 22, and the outer layer liquid guiding cotton 212 is fixed outside the inner layer liquid guiding cotton 211. The liquid matrix inside the liquid storage cavity 120 is preferentially provided to the outer layer liquid guiding cotton 212 and is provided to the inner layer liquid guiding cotton 211 through the outer layer liquid guiding cotton 212. The heating element 22 is made of a heating metal material such as iron chromium, nickel chromium, titanium, 316L stainless steel, palladium silver, tungsten alloy, etc. The heating element 22 is set as a sheet with a grid structure, and the heating element 22 is fixed inside the inner cavity of the inner layer liquid guiding cotton 211 after being wound.

[0064] The atomization assembly 20 further includes a bracket 23 and a sleeve 24. The sleeve 24 is sleeved outside the bracket 23 and abuts against the outer flange of the bracket 23. The bracket 23 has a hollow inner cavity. After the heating element 22 is fixed inside the inner liquid guide cotton 211, it is placed in the inner cavity of the bracket 23. The bottom of the inner liquid guide cotton 211 abuts against the inner flange of the bracket 23, and the outer liquid guide cotton 212 is fixed between the bracket 23 and the sleeve 24. A plurality of first liquid guide holes are provided on the sleeve 24, and a plurality of second liquid guide holes are further provided on the bracket 23. The liquid matrix inside the liquid storage cavity 120 is supplied to the outer liquid guide cotton 212 through the plurality of first liquid guide holes. The liquid matrix stored in the outer liquid guide cotton 212 is supplied to the inner liquid guide cotton 211 through the plurality of second liquid guide holes, and is supplied to the heating element 22 through the inner liquid guide cotton 211. A sealing seat 25 is further provided at the bottom opening of the bracket 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 channel 70. The atomization channel 70 includes an air inlet section and an air outlet section. Air enters through the air inlet section. 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 channel 70 is defined by the inner cavity of the bracket 23, and the air outlet section of the atomization channel 70 is defined by the inner cavity of the sleeve 24. One end of the sleeve 24 away from the bracket 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 guide 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.

[0067] The base 30 is connected to the open end of the housing 10. A part of the base 30 is embedded in the sealing element 26 to provide the structural strength of the sealing element 26.

[0068] A liquid absorption element 80 is further provided in the inner cavity of the base 30. The liquid absorption element 80 is made of a limiting cotton material. The liquid absorption element 80 is arranged below the atomization channel 70 and is used to absorb the condensate flowing out from the end of the atomization channel 70.

[0069] The atomizer 100 further includes a magnetic element, and the atomizer 100 is magnetically connected to a magnetic attraction element provided inside the power supply assembly 200 through this 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, and the cross section of this magnet is set to 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.

[0070] 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 83 inside the power supply assembly 200. The above 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 83 inside the power supply assembly 200 and conduct electricity.

[0071] The atomizer 100 is further provided with an air inlet channel 50. External air flow is provided to the atomization channel 70 through the air inlet channel 50. In the electronic atomization device 1, there is also an induction air channel 60 connected to the induction side of the air flow induction switch 95. The part of the induction air channel 60 disposed in the atomizer 100 is usually combined with the air inlet channel 50 into one channel. When the air intake volume of the air inlet channel 50 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 channel 60 connected to the air flow induction switch 95 is also large, which further causes the induction side and the atmospheric 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, and further affecting the normal use of the electronic atomization device 1.

[0072] Reference Figure 2 、 Figure 3 、 Figure 6 and Figure 9, in some embodiments of the present application, by optimizing the internal structure of the atomizer 100, the air intake volume of the air intake channel 50 of the atomizer 100 will not interfere with the air flow rate of the induction air channel 60, so that during the process of adjusting the air of the atomizer 100, the air flow induction switch 95 can work normally.

[0073] The atomizer 100 further includes an air adjustment assembly 40, which is connected to the base 30. The air adjustment assembly 40 and the base 30 jointly define an air intake channel 50. The air intake channel 50 is provided with a first air intake 51 and a first air outlet 52. The first air intake 51 is connected to the external air flow. The air adjustment assembly 40 is configured to be rotatable or movable relative to the base 30, so as to adjust the cross-sectional area of the first air outlet 52 or the first air intake 51.

[0074] Wherein, the base 30 or the air adjustment assembly 40 is further provided with an induction air channel 60. The induction air channel 60 is provided with a second air intake 61 and a second air outlet 62. The second air intake 61 is configured to be connected to the air flow induction switch 95, and the second air outlet 62 is connected to the first air outlet 52 and is connected to the air intake end of the atomization channel 70.

[0075] Along the width direction or the thickness direction of the housing 10, the atomization channel 70, the induction air channel 60 and the air intake channel 50 are arranged at intervals in sequence.

[0076] By arranging the air intake channel 50 and the induction air channel 60 at intervals, during the process of adjusting the cross-sectional area of the first air outlet 52 of the air intake channel 50 by the air adjustment assembly 40, the air flow rate inside the induction air channel 60 will not change, and thus will not interfere with the normal operation of the air flow induction switch 95. Further, by arranging the atomization channel 70 and the induction air channel 60 at intervals, the condensate flowing out of the atomization channel 70 is difficult to enter the induction air channel 60, thereby preventing the condensate from flowing into the air flow induction switch 95 through the induction air channel 60 and corroding the air flow induction switch 95.

[0077] In the embodiment provided by the present application, the atomizer 100 is set in a box shape. The width direction of the housing 10 is as Figure 3 shown by the arrow Y in the figure. Among them, the atomization channel 70 is configured to extend basically along the height direction of the housing 10, the air intake channel 50 is configured to extend basically along the height direction of the housing 10, the induction air channel 60 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 3 shown by the arrow X in the figure.

[0078] As Figure 2The airflow directions of the induction air passage 60, the intake air passage 50, and the atomization air passage 70 inside the electronic atomization device 1 are marked as shown. The top surface where the first air outlet 52 of the intake air passage 50 is located is set lower than the top surface where the second air outlet 62 of the induction air passage 60 is located.

[0079] 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 surface where the first air outlet 52 of the intake air passage 50 is located is lower than the top surface where the second air outlet 62 of the induction air passage 60 is located, the condensate will overflow from the first air outlet 52 preferentially, further preventing the condensate from entering the induction air passage 60, and thus preventing the airflow induction switch 95 from being corroded by the condensate.

[0080] Further referring to Figure 10 , the second air outlet 62 of the induction air passage 60 is arranged closer to the intake end of the atomization air passage 70 than the first air outlet 52 of the intake air passage 50.

[0081] During the process of the user sucking at the mouthpiece, negative pressure is successively formed at the mouthpiece 111 and inside the atomization air passage 70. Since the second air outlet 62 of the induction air passage 60 is arranged closer to the intake end of the atomization air passage 70 than the first air outlet 52 of the intake air passage 50, negative pressure will be formed inside the induction air passage 60 preferentially compared to the inside of the intake air passage 50. Thus, the airflow induction switch 95 can detect the negative pressure faster, thereby improving the sensitivity of the airflow induction switch 95.

[0082] Continuing to refer to Figure 2 , Figure 6 , Figure 10 and Figure 14 As shown in

[0083] , the air regulating assembly 40 includes an air regulating switch 41. The air regulating switch 41 is connected to the bottom of the base 30. By rotating the air regulating switch 41, the air regulating assembly 40 can rotate relative to the base 30 to adjust the cross-sectional area of the first air outlet 52.

[0084] The air regulating switch 41 is arranged 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. Children need to separate the atomizer 100 from the power supply assembly 200 before they can operate the air regulating assembly 40, so that the above air regulating assembly 40 has a child lock function.

[0084] Furthermore, the air regulating switch 41 is set as a rotary switch. By rotating the rotation angle of the air regulating switch 41, the cross-sectional area of the first air outlet 52 is adjusted, and the operation is simple and convenient.

[0085] In other alternative examples, the air regulating switch 41 can also be set as a sliding switch, and the sliding switch can be further set to slide along the width direction or the height direction of the housing 10 so as to adjust the cross-sectional area of the first air outlet 52.

[0086] Further referring to Figure 4 and Figure 6 , the air regulating switch 41 includes a main body portion 413 and an operating portion 411 provided at one end of the main body portion 413. The operating portion 411 protrudes relative to the bottom end surface of the base 30, which is convenient for the user to operate the air regulating switch 41. The operating portion 411 includes a first operating protrusion and a second operating protrusion arranged at intervals. The user drives the air regulating switch 41 to rotate by applying forces to the first operating protrusion and the second operating protrusion. The base 30 includes an air guiding portion 31, and the air guiding portion 31 is provided with a through hole. The air regulating switch 41 is fixed in the through hole. A flange 414 is further provided on the main body portion 413 of the air regulating switch 41, and a convex table surface is provided on the inner surface of the air guiding portion 31. The flange 414 of the air regulating switch 41 abuts against the convex table surface of the air guiding portion 31.

[0087] A plurality of sealing rings 43 are further sleeved on the outer surface of the main body portion 413. The plurality of sealing rings 43 are used to seal the connection gap between the air regulating switch 41 and the air guiding portion 31 of the base 30. The plurality of sealing rings 43 are located above the flange 414 of the air regulating switch 41, further enhancing the sealing performance of the atomizer 100.

[0088] Further referring to Figure 3 , Figure 4 , the air regulating switch 41 further includes an air regulating cover 42. The air regulating cover 42 is connected to one end of the air regulating switch 41. An operating portion 411 is provided at the other end of the air regulating switch 41. An air outlet hole 32 is provided on the top of the air guiding portion 31 of the base 30. The air regulating cover 42 is located above the top end surface of the air guiding portion 31. The air regulating cover 42 is set to be able to block the air outlet hole 32. The unblocked part of the air outlet hole 32 forms the first air outlet 52. By rotating the air regulating assembly 40, the cross-sectional area of the air outlet hole 32 covered by the air regulating cover 42 can be adjusted.

[0089] It can be understood that, compared with setting the air regulating cover 42 at the first air inlet 51 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 be misoperated when the electronic atomization device is shaken by an external force. In the embodiment 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 switch 41 to rotate to adjust the cross-sectional area of the air outlet hole 32, which can effectively avoid misoperation.

[0090] In a specific implementation, the cross-section of the air outlet hole 32 provided on the air guiding part 31 of the base 30 is set as a sector. The air adjusting cover 42 is provided with a notch, and the cross-sectional area of the notch is not less than the cross-sectional area of the air outlet hole 32. The atomizer 100 has an open state and a closed state. When the atomizer 100 is in the closed state, as Figures 5 to 8b shown, the air adjusting cover 42 is configured to completely block the air outlet hole 32; when the atomizer 100 is in the open state, as Figures 8a to 11 shown, the notch provided on the air adjusting cover 42 is arranged to face at least part of the air outlet hole 32, so that at least part of the air outlet hole 32 is available for external air flow to flow out.

[0091] Further referring to Figures 5 to 8b , when the atomizer 100 is in the closed state, the connection line between the two operation protrusions of the air adjusting switch 41 coincides with the width direction of the housing 10. By judging the position state of the two operation protrusions, it can be further known whether the air adjusting switch 41 rotates in place.

[0092] Further referring to Figures 9 to 12 , when the atomizer 100 is in the open state, the connection line between the two operation protrusions of the air adjusting switch 41 is arranged at an angle with the width direction of the housing 10.

[0093] Referring to Figures 9 to 16 , 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 8a to 11 shown, the air outlet hole 32 is completely staggered from the air adjusting cover 42, and the cross-sectional area of the first air outlet 52 is in the maximum state. Correspondingly, the air intake volume of the air intake 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 12 to 15 shown, at least part of the air outlet hole 32 is staggered from the air adjusting cover 42. For example, when the atomizer 100 is in a semi-open state, the cross-sectional area of the air outlet hole 32 staggered from the air adjusting cover 42 occupies half of the total cross-sectional area of the air outlet hole 32.

[0094] Further referring to Figures 9 to 12 , when the atomizer 100 is in the fully open state, the connection line between the two operation protrusions of the air adjusting switch 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 operation protrusions, it can be further known whether the air adjusting switch 41 rotates in place.

[0095] Further referring to Figures 13 to 16When the atomizer 100 is in a partially open state, the line between the two operating protrusions of the gas regulating switch 41 is set at an angle with the width direction or the thickness direction of the shell 10. By judging the position state of the two operating protrusions, it can be known whether the gas regulating switch 41 is rotated into place.

[0096] It is understandable that the relative position between the two operating protrusions of the above-mentioned air regulating switch 41 and the shell 10 can be adjusted according to design requirements. For example, when the atomizer 100 is in a closed state, the line between the two operating protrusions can be set to be parallel to the thickness direction of the shell 10. When the atomizer 100 is in a fully open state, the line between the two operating protrusions can be set to be parallel to the width direction of the shell 10.

[0097] In other optional examples, a plurality of spaced apart air outlet holes 32 are provided on the air guide portion 31 of the base 30, and the relative position state between the air regulating cover 42 and the plurality of air outlet holes 32 is controlled by rotating the air regulating assembly 40. For example, when the atomizer 100 is in a closed state, the air regulating cover 42 completely blocks the plurality of air outlet holes 32; when the atomizer 100 is in a fully open state, the air regulating cover 42 is completely staggered from the plurality of air outlet holes 32; when the atomizer 100 is in a partially open state, the air regulating cover 42 blocks a portion of the air outlet holes 32, and another portion of the air outlet holes 32 are staggered from the air regulating cover 42.

[0098] Further integration Figure 1 , Figure 2 and Figure 3 As shown in the figure, a connection opening 98 is formed after the atomizer 100 and the power supply assembly 200 are connected, and external air can enter the air inlet channel 50 through the connection opening 98. The air regulating switch 41 is accommodated in the through hole of the air guide portion 31 of the base 30, and the air regulating switch 41 can rotate relative to the air guide portion 31 of the base 30. An air guiding gap is formed between the inner surface of the air guide portion 31 and the outer surface of the air regulating switch 41, and the air guiding gap forms a part of the air inlet channel 50. The part of the air guiding gap located on the bottom end surface of the base 30 forms the first air inlet 51. Therefore, during the rotation of the air regulating switch 41, the cross-sectional area of ​​the first air inlet 51 remains unchanged, and the air regulating switch 41 further drives the air regulating cover 42 to rotate during the rotation, and the air regulating cover 42 can adjust the cross-sectional area of ​​the air outlet hole 32 during the rotation.

[0099] The arrangement structure of the air inlet channel 50 allows the air inlet channel 50 to extend substantially along the height direction of the housing 10 , so that the airflow inside the atomizer 100 flows more gently, which is beneficial to reducing the noise generated by the airflow and improving the user experience.

[0100] Further references Figure 2, the above-mentioned air regulating switch 41 is fixed on the air guiding part 31 of the base 30, and the top of the air regulating switch 41 abuts against the sealing element 26, so that the air regulating assembly 40 can be stably received inside the housing 10.

[0101] Continue to refer to Figures 5 to 16 As shown, the air regulating assembly 40 is provided with a through hole 44 extending along its central axis, and the through hole 44 is defined as an induction air passage 60. The through hole 44 includes a first through hole penetrating the air regulating switch 41 and a second through hole provided at the center of the air regulating cover 42. The second air inlet 61 is located at the bottom of the air regulating switch 41, and the second air outlet 62 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 61 and the second air outlet 62 remain unchanged. Therefore, even if the atomizer 100 is set to the fully open state and external air flows into the intake passage 50, and the induction air passage 60 is arranged close to the atomization passage 70, the negative pressure generated inside the atomization 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.

[0102] Refer to Figure 17 , the through hole 44 provided on the air regulating switch 41 is located between two operation protrusions. On the bottom end surface of the base 30, a first magnetic element 81, an air regulating switch 41, two electrode posts 83, and a second magnetic element 82 are sequentially arranged. The air regulating switch 41 is provided with a first through hole and two operation protrusions located on both sides of the first through hole. A bottom air inlet 33 is also provided between the operation switch and the base 30, and the bottom air inlet 33 is located between the two first magnetic elements 81.

[0103] At one end of the air regulating switch 41 away from the operation part 411, a first buckle part 4121 and a second buckle part 4122 are arranged at intervals. The air regulating cover 42 is snapped onto the air regulating switch 41 through the first buckle part 4121 and the second buckle part 4122, so that the air regulating cover 42 can be stably connected to the air regulating switch 41.

[0104] At one end of the air regulating switch 41 away from the operation part 411, a first convex column 4131 and a second convex column 4132 are also provided. A first interval and a second interval are formed between the first buckle part 4121 and the second buckle part 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 set higher than the top end surfaces of the first buckle part 4121 and the second buckle part 4122. The top end surfaces of the first convex column 4131 and the second convex column 4132 abut against the sealing element 26.

[0105] Further, air guiding intervals are respectively formed between both sides of the first convex post 4131 and the first snap portion 4121 and the second snap portion 4122, and air guiding intervals are respectively formed between both sides of the second convex post 4132 and the first snap portion 4121 and the second snap portion 4122. The air guiding intervals define the second air outlet 62 of the induction air passage 60.

[0106] Continue to refer to Figure 2 , an air passage seal 97 is further provided on the power supply assembly 200. The air passage seal 97 is made of flexible silica gel material. The air passage seal 97 is provided with induction air holes, and the induction air holes are communicated with the sensing end of the air flow induction switch 95. A part of the top surface of the air passage seal 97 can be inserted into the through hole 44 of the air adjustment switch 41, so as to seal the bottom of the induction air passage 60 defined by the air adjustment switch 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.

[0107] In other alternative examples, the air passage seal 97 provided on the power supply assembly 200 and the air adjustment switch 41 can be integrally provided, further saving the internal space of the electronic atomization device 1.

[0108] As Figure 18 shown by the arrow marked, the figure shows the route map of the condensate overflowing from the inside of the atomizer 100 through the atomization channel 70 to the outside. Since the top surface where the second air outlet 62 of the induction air passage 60 is located is higher than the top surface where the first air outlet 52 of the air intake passage 50 is located, when more condensate accumulates in the inner cavity of the base 30, the condensate preferentially enters the air intake passage 50 through the first air outlet 52. 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 induction air passage 60 will further block the condensate from entering the induction air passage 60.

[0109] As Figure 3 、 Figure 4 、 Figure 19 、 Figure 20 、 Figure 21 、 Figure 22a and Figure 22b shown, the atomizer 100 is provided with a liquid injection structure. A liquid injection hole 14 is provided at one end of the housing 10, and a sliding cover 131 and a liquid injection hole seal 132 for sealing and opening the liquid injection hole 14. The sliding cover 131 and the liquid injection hole seal 132 are connected to form a sliding cover assembly 13. The sliding cover assembly 13 and the mouthpiece 11 are located at the same end of the housing 10. By driving the sliding cover assembly 13 to slide away from the mouthpiece 11, the liquid injection hole 14 can be opened. By driving the sliding cover assembly 13 to slide towards the side close to the mouthpiece 11, the liquid injection hole 14 can be closed.

[0110] A boss portion 133 is provided on the back surface of the sliding cover assembly. The boss portion 133 is provided on the liquid injection hole seal 132. The liquid injection hole 14 is provided as a counterbore. The boss portion 133 is configured to be embedded into the liquid injection hole 14, so as to seal the periphery of the liquid injection hole 14, and further enable the sliding cover assembly 13 to stably seal the liquid injection hole 14.

[0111] At least a part of the top end surface of the housing 10 is recessed inward to form a groove 15. The groove 15 extends to the side portion of the housing 10. The sliding cover assembly 13 is configured to slide within the groove 15.

[0112] Compared with arranging the above-mentioned sliding cover assembly 13 on the front side surface, the rear side surface, the left side surface and the right side surface of the housing 10, the space where the sliding cover assembly 13 can be installed and slide is limited, which makes the liquid injection operation of the user inconvenient. By arranging the above-mentioned sliding cover assembly 13 on the top end surface of the housing 10, the sliding range of the sliding cover assembly 13 is larger and the operation is convenient.

[0113] 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 set in the style of an operation indication arrow, and is used to prompt the user of the operation direction of the sliding cover assembly 13.

[0114] Continue to refer to Figure 21 , Figure 22a and Figure 22b , a sliding guide groove 134 is further provided inside the groove 15. The sliding guide groove 134 is located on both sides of the 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 groove 15 of the housing 10.

[0115] A limiting groove 136 is further provided inside the groove 15. The limiting groove 136 is further recessed from the bottom wall where the groove 15 is located. Correspondingly, a limiting protrusion 137 is provided on the back surface of the sliding cover assembly 13. 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 groove 15 of the housing 10.

[0116] Continue to refer to Figure 22bA plurality of damping ridges 138 are provided on the back of the sliding cover assembly 13, and the plurality of damping ridges 138 are provided on the injection hole seal 132. The plurality of damping ridges 138 are provided to contact with the shell 10 to prevent a gap from being formed between the bottom end surface of the sliding cover assembly 13 and the shell 10, thereby causing the sliding cover assembly 13 to shake in the groove 15.

[0117] refer to Figures 23 to 26 As shown, when the injection hole 14 of the atomizer 100 is in a closed state, one side of the sliding cover assembly 13 abuts against a side wall where the groove 15 is located, the limiting protrusion 137 set on the sliding cover 131 abuts against a side wall where the limiting groove 136 is located, and the boss portion 133 set on the injection hole seal 132 forms a stable circumferential seal with the injection hole, thereby preventing the liquid matrix inside the liquid storage chamber from leaking. The top surface of the ridge 135 set on the sliding cover 131 abuts against the bottom wall where the sliding guide groove 134 is located, and the damping ridge 138 set on the injection hole seal 132 keeps in contact with the housing 10, thereby preventing the sliding cover assembly 13 from shaking in the 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 ridge 138 and the housing 10, the sliding cover assembly 13 can be stably accommodated in the groove 15 without shaking.

[0118] refer to Figures 27 to 30 As shown, when the injection hole 14 of the atomizer 100 is in an open state, the boss portion 133 provided on the injection hole seal 132 is completely offset from the injection hole, and the boss portion 133 is further accommodated 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.
