[0028] The present application provides an electronic atomization device 300, see Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the electronic atomization device provided in the present application.

[0029] The electronic atomization device 300 includes a host 200 and an atomizer 100 , wherein the host 200 is connected to the atomizer 100 and supplies power to the atomizer 100 .

[0030] The electronic atomization device 300 can be used to atomize aerosol substrates such as cigarette liquid, liquid medicine or nutrient solution, that is, to atomize the liquid aerosol substrate to form an aerosol for the user to inhale. Among them, the host 200 can be detachably connected to the atomizer 100 and power the atomizer 100, so that the atomizer 100 can be replaced; or the host 200 and the atomizer 100 are an integrated structure and power the atomizer 100. The atomizer 100 is used to store the aerosol substrate and atomize the aerosol substrate to form an aerosol for the user to absorb.

[0031] The host 200 includes an electrically connected control element and a battery. The control element is also used to electrically connect to the atomizer 100 to identify status information of the atomizer 100 and control the power supply to the atomizer 100 according to the identified status information.

[0032] Combined with reference Figure 1 and Figure 2 ,in Figure 2 yes Figure 1 A schematic cross-sectional structure diagram of an embodiment of an atomizer in an electronic atomization device is shown.

[0033] like Figure 1 As shown, the nebulizer 100 includes a shell component 1 and an atomizing component 30. The shell component 1 is provided with an atomizing channel 101 and is formed with a first liquid suction chamber 102 and a second liquid suction chamber 103 spaced apart along the axis of the atomizing channel 101. The first liquid suction chamber 102 and the second liquid suction chamber 103 are both connected to the atomizing channel 101. The atomizing component 30 is arranged in the atomizing channel 101, and the atomizing component 30 is used to absorb liquid and generate an aerosol matrix in the atomizing channel 101. The first liquid suction component 11 is arranged in the first liquid suction chamber 102, and the second liquid suction component 21 is arranged in the second liquid suction chamber 103. The first liquid suction port 104 communicating with the atomizing channel 101 and the first liquid suction chamber 102 is located above the atomizing component 30, and the second liquid suction port 105 communicating with the atomizing channel 101 and the second liquid suction chamber 103 is located below the atomizing component 30.

[0034] A liquid storage chamber is provided in the housing component 1, and the atomizing component 30 absorbs liquid from the liquid storage chamber and generates an aerosol in the atomizing channel 101. The atomizing channel 101 relatively passes through the liquid storage chamber, and the first liquid absorption chamber 102 and the second liquid absorption chamber 103 are both isolated from the liquid storage chamber. The first liquid absorption member 11 located in the first liquid absorption chamber 102 and the second liquid absorption member 21 located in the second liquid absorption chamber 103 are used to absorb condensed liquid generated by aerosol condensation, large-particle aerosol matrix that is not completely atomized, and some possible leakage, so as to prevent these liquids from being accidentally inhaled into the mouth or leaking to the host 200.

[0035] The aerosol generated by the atomization component 30 may condense under certain conditions. For example, the aerosol may condense when it hits the tube wall with a lower temperature, or the large-particle aerosol matrix that is not completely atomized may easily form aggregated liquid when it contacts the tube wall. Due to the production and assembly errors of the atomizer 100, some atomizers 100 may have a higher risk of leakage, and the leaked aerosol matrix may enter the mouth or flow to the host 200, which may cause adverse effects.

[0036] If the liquid adsorbed on the tube wall of the atomization channel 101 is not disposed of in time, it may be sucked into the mouth when the atomizer 100 is used next time, or it may flow back to the atomization component 30, resulting in a poor taste of the aerosol when atomized again, or it may leak to the host 200, causing the host 200 to malfunction.

[0037] In the present application, a first liquid suction chamber 102 and a second liquid suction chamber 103 connected to the atomization channel 101 are formed on the shell component 1, and a first liquid suction port 104 and a second liquid suction port 105 are respectively provided above and below the atomization component 30, so that liquids such as condensed liquid above the atomization component 30 can flow along the tube wall of the atomization channel 101 through the first liquid suction port 104 to the first liquid suction chamber 102 and be absorbed by the first liquid suction component 11, and liquids such as leaked liquid below the atomization component 30 can flow along the tube wall of the atomization channel 101 through the second liquid suction port 105 to the second liquid suction chamber 103 and be absorbed by the second liquid suction component 21, thereby being able to extremely effectively eliminate various types of liquids in the atomization channel 101, avoiding the risk of taste degradation or damage to the host 200 caused by the presence of condensed liquid or leaked liquid.

[0038] The first liquid absorbent member 11 and the second liquid absorbent member 21 can be made of materials with excellent liquid absorption capacity such as cotton fiber or linen fiber, which can absorb liquid and prevent the liquid from flowing freely. Therefore, when the atomizer 100 is used, it can be placed in any posture, such as the atomizer 100 is inverted, horizontal or tilted, and the liquid absorbed by the first liquid absorbent member 11 and the second liquid absorbent member 21 will not leak out.

[0039] The atomization channel 101 , the first liquid suction chamber 102 and the second liquid suction chamber 103 are defined and formed by the structure in the housing assembly 1 . For example, the housing assembly 1 only contains a single liquid storage chamber, and the single liquid storage chamber supplies liquid to the atomization assembly 30 .

[0040] In this embodiment, refer to Figure 2The shell component 1 includes a detachably connected liquid storage tank 10 and an atomizing liquid storage tank 20, wherein a first liquid storage cavity 120 is provided in the liquid storage tank 10, and a second liquid storage cavity 220 is provided in the atomizing liquid storage tank 20. When the liquid storage tank 10 and the atomizing liquid storage tank 20 are in a connected state, the first liquid storage cavity 120 can supply liquid to the second liquid storage cavity 220, wherein the capacity of the first liquid storage cavity 120 is greater than the capacity of the second liquid storage cavity 220, that is, the first liquid storage cavity 120 serves as a main liquid storage cavity, and the second liquid storage cavity 220 serves as a secondary liquid storage cavity, and the atomizing component 30 directly consumes the aerosol matrix in the second liquid storage cavity 220, and the first liquid storage cavity 120 can replenish the second liquid storage cavity 220 with liquid.

[0041] Furthermore, since the aerosol matrix in the second liquid storage chamber 220 will absorb part of the heat generated by the operation of the atomization assembly 30, there is a risk that part of the aerosol matrix will deteriorate due to the heat. By providing the first liquid storage chamber 120 and the second liquid storage chamber 220, the aerosol matrix in the second liquid storage chamber 220 can be prevented from flowing back to the first liquid storage chamber 120, thereby preventing the deteriorated aerosol matrix from spreading.

[0042] The capacity of the first liquid storage chamber 120 can be 6-15ml, for example, it can be 6ml, 8ml, 10ml, 12ml, 13ml or 15ml; the capacity of the second liquid storage chamber 220 can be 1-3ml, for example, it can be 1.0ml, 1.5ml, 2.0ml, 2.5ml or 3.0ml.

[0043] Relatively speaking, the first liquid storage chamber 120 is of large capacity, and the second liquid storage chamber 220 is of small capacity. In the transportation scenario, the liquid storage tank 10 and the atomization liquid tank 20 are in a separated state, that is, the second liquid storage chamber 220 can be empty or carry a small amount of liquid, thereby effectively reducing the risk of leakage of the atomizer 100 due to factors such as vibration in the transportation scenario.

[0044] Combined with reference Figure 1 and Figure 2 A first liquid suction chamber 102 is provided in the liquid storage tank 10, a second liquid suction chamber 103 is provided in the atomizing liquid tank 20, and the atomizing channel 101 includes a first channel 106 provided in the liquid storage tank 10 and a second channel 107 provided in the atomizing liquid tank 20; wherein a first liquid suction port 104 is defined between the first channel 106 and the second channel 107, the atomizing assembly 30 is provided in the second channel 107, and an end of the second channel 107 away from the first channel 106 is connected to the second liquid suction chamber 103.

[0045] The first liquid suction chamber 102 and the second liquid suction chamber 103 are separately arranged in different chambers, thereby reducing the structural complexity of the shell assembly 1 and avoiding high production costs and complex assembly processes due to an overly complex structure.

[0046] Specifically, the liquid storage tank 10 is provided with a first liquid storage chamber 120, a first channel 106 and a first liquid suction chamber 102. The first liquid suction chamber 102 is isolated from the first liquid storage chamber 120. The first channel 106 passes through the first liquid storage chamber 120 and is connected to the suction nozzle at the top of the liquid storage tank 10. The first liquid suction chamber 102 is connected to a port of the first channel 106 facing the atomizing liquid tank 20. Therefore, there is no need to additionally set a hole structure on the side wall of the first channel 106 to connect the first liquid suction chamber 102, which makes the structure of the liquid storage tank 10 more concise and reliable. The second liquid suction port 105 is a port of the second channel 107 away from the first channel 106. Therefore, the second channel 107 can also be used as a complete channel without making any structural changes, which also makes the structure of the atomizing liquid tank 20 more concise and reliable.

[0047] Further, after the liquid storage tank 10 is connected to the atomizing liquid tank 20 , a first liquid suction port 104 is formed between the first channel 106 and the second channel 107 , that is, the first liquid suction port 104 is defined and formed by the gap between the first channel 106 and the second channel 107 .

[0048] In some embodiments, the first liquid suction port 104 may be defined by a gap between the first channel 106 and the second channel 107 in the axial direction, or may be defined by a gap between the first channel 106 and the second channel 107 in the radial direction.

[0049] Combined with reference Figure 2 and Figure 3 ,in Figure 3 yes Figure 2 A schematic cross-sectional structural diagram of the liquid storage tank in the atomizer shown.

[0050] In this embodiment, one end of the first channel 106 facing the second channel 107 is a bell mouth 108, and one end of the second channel 107 facing the first channel 106 is inserted into the bell mouth 108. The first liquid suction port 104 is a gap formed between the end of the second channel 107 and the wall of the bell mouth 108.

[0051] The small end of the bell mouth 108 has a small diameter, and the large end thereof has a large diameter, and the large end thereof faces the second channel 107. The liquid gathered on the first channel 106 can be guided by the bell mouth 108 to the outside of the second channel 107 and flow to the first liquid absorbing member 11, thereby effectively preventing the liquid from flowing back to the second channel 107.

[0052] Optionally, both the first channel 106 and the second channel 107 are straight channels, and the diameter of the first channel 106 is larger than the diameter of the second channel 107 , thereby preventing the liquid condensed on the first channel 106 from flowing into the second channel 107 .

[0053] Combined with reference Figure 3 and Figure 4 ,in Figure 4 yes Figure 3 Schematic diagram of the exploded structure of the liquid storage tank shown. In this embodiment, the liquid storage tank 10 includes a first shell 12, a first base 13 and a fixed cover 14, the first base 13 is connected to the port of the first shell 12 facing the atomized liquid tank 20 and defines a first liquid storage chamber 120 together, a bell mouth 108 and a receiving groove 130 surrounding the bell mouth 108 are provided on the side of the first base 13 facing the atomized liquid tank 20, a vent pipe 122 in the first shell 12 is connected to the first base 13 and communicates with the bell mouth 108, the fixed cover 14 is connected to the first base 13 and covers the receiving groove 130 to form a first liquid suction chamber 102, a through hole 140 connected to the bell mouth 108 is provided on the fixed cover 14, and the second channel 107 is connected to the first channel 106 through the through hole 140, and the first channel 106 includes a vent pipe 122 and a bell mouth 108 that are connected.

[0054] The first shell 12 is provided with a connected suction nozzle 121 and a ventilation pipe 122. The first base 13 can be connected to the open end of the first shell 12 through a seal, or the first base 13 is bonded or welded to the open end, so as to define a first liquid storage chamber 120 with the first shell 12. The ventilation pipe 122 is connected to the first base 13 and connected to the bell mouth 108. The ventilation pipe 122 and the bell mouth 108 constitute the first channel 106.

[0055] Of course, a sealing structure is also provided between the vent pipe 122 and the first base 13 to prevent liquid leakage.

[0056] A receiving groove 130 is provided around the bell mouth 108 on one side of the first base 13 facing away from the first liquid storage cavity 120, and the first liquid absorbent member 11 is received in the receiving groove 130. The fixed cover 14 is provided on the open end of the first shell 12 and covers the receiving groove 130 to form a first liquid absorbent cavity 102 for receiving the first liquid absorbent member 11, wherein a gap exists between the edge of the fixed cover 14 facing the bell mouth 108 and the wall surface of the bell mouth 108, so that the first liquid absorbent cavity 102 can be connected to the first channel 106 through the gap, and the bell mouth 108 can guide the liquid to the first liquid absorbent member 11.

[0057] Furthermore, a plurality of condensation adsorption grooves 131 are disposed on the bottom wall of the accommodating tank 130 , and a first gap 132 is formed between the first liquid absorbing member 11 and the outer wall of the bell mouth 108 . The first gap 132 communicates the condensation adsorption grooves 131 and the first liquid absorbing port 104 .

[0058] Specifically, a through hole corresponding to the bell-mouth 108 is provided on the first liquid absorption member 11, and a first gap 132 is formed between the inner wall surface of the through hole and the outer wall surface of the bell-mouth 108. The number of condensation adsorption grooves 131 can be three or four, etc., arranged around the bell-mouth 108, so that the tube wall of the bell-mouth 108 is relatively protruding from the condensation adsorption groove 131 and lower than the top of the containing groove 130. Therefore, when the user uses the atomizer 100 in a normal posture, the grooves of the containing groove 130 and the condensation adsorption groove 131 are relatively facing downward, and the large particle aerosol gathered in the condensation adsorption groove 131 cannot rise due to being blocked by the bottom of the condensation adsorption groove 131, and is also blocked by the tube wall of the bell-mouth 108 laterally, so it is also difficult to flow back to the atomization channel 101 through the first gap 132.

[0059] Through the first gap 132 formed, large-particle aerosol formed in the atomization channel 101 due to insufficient atomization can enter the condensation adsorption groove 131 through the first liquid absorption port 104 and the condensation adsorption groove 131, so that it can be gathered in the condensation adsorption groove 131, and after condensing into liquid, it can be easily absorbed by the first liquid absorption member 11.

[0060] Specifically, among the aerosol components generated by the atomization assembly 30 in the atomization channel 101, some aerosol matrix may not be fully atomized due to some conditions, resulting in large-particle aerosol. This type of component does not fully express the mouthfeel of the aerosol matrix. Filtering it out will be able to optimize the mouthfeel of the aerosol. The rising rate of the large-particle aerosol is slower than the rising rate of the aerosol generated by full atomization, so it rises relatively close to the wall of the atomization channel 101, and can enter the condensation adsorption tank 131 through the first liquid suction port 104 and the first gap 132.

[0061] By further forming a condensation adsorption groove 131, the first liquid absorption member 11 is relatively covered with the condensation adsorption groove 131, and the condensation adsorption groove 131 is connected to the first liquid absorption port 104 through the first gap 132, and then the large-particle aerosol that is not fully atomized can be collected through the space defined by the condensation adsorption groove 131, which can effectively reduce the content of the large-particle aerosol that is not fully atomized in the aerosol generated by atomization, thereby optimizing the taste of the aerosol, so that the taste of the aerosol absorbed by the user is more fully expressed.

[0062] See also Figure 5 , Figure 5 yes Figure 2 A schematic cross-sectional structural diagram of the atomizing liquid tank in the atomizer shown.

[0063] The atomizing liquid tank 20 includes a second shell 22, a second base 23 and a bottom cover 24. The second base 23 is connected to the second shell 22 and defines a second liquid storage chamber 220. The second shell 22 is provided with a liquid column 221 and an insertion tube 222. The liquid column 221 is used to be plugged into the first base 13 to connect the first liquid storage chamber 120 and the second liquid storage chamber 220. The atomizing component 30 is connected to the insertion tube 222 and the second base 23. A first liquid suction port 104 is formed between the insertion tube 222 and the wall of the bell mouth 108. The bottom cover 24 is covered at one end of the second base 23 away from the liquid storage tank 10, and is connected to the second base 23 to form a second liquid suction chamber 220. The second base 232 is provided with a second liquid suction port 105 connecting the atomizing component 30 and the second liquid suction chamber 103.

[0064] The second housing 22 is provided with a liquid column 221 and an insertion tube 222 at one end facing the liquid storage tank 10, and the other end of the second housing 22 facing away from the liquid storage tank 10 is an open end. The second base 23 can be connected to the open end of the second housing 22 through a seal, or the second base 23 is bonded or welded to the open end, so as to define a second liquid storage chamber 220 with the second housing 22. One end of the atomizer assembly 30 is connected to the second base 23, and the other end thereof is inserted into the insertion tube 222, and the second base 32 is provided with a second liquid suction port 105 connected to the atomizer assembly 30, and the second channel 107 is formed by the insertion tube 222, the channel in the atomizer assembly 30 and the second liquid suction port 105. The atomizer assembly 30 and the second base 23 are sealed to prevent leakage.

[0065] In some embodiments, the second liquid storage chamber 220 can be directly used to store liquid aerosol matrix.

[0066] However, due to errors or defects in the material, process or assembly process, the sealing structure may fail or the reliability may be reduced, and there may be a risk of leakage at each connection of the second liquid storage chamber 220. Therefore, the present application further provides a liquid storage part 25 in the second liquid storage chamber 220; the atomization component 30 passes through the liquid storage part 25 and connects the insertion tube 222 and the second base 23, and the atomization component 30 is used to absorb liquid from the liquid storage part 225 in the second liquid storage chamber 220 and atomize it.

[0067] The material of the liquid storage component 25 can be polyester fiber, polypropylene fiber or non-woven fabric, etc. It has high and uniform adsorption capacity, can absorb a certain amount of aerosol matrix, and it also has good liquid conduction ability and stable liquid conduction rate, ensuring that the aerosol matrix can be smoothly transmitted to the atomization component 30.

[0068] By providing a liquid storage component 25 capable of storing aerosol matrix, the fluidity of the aerosol matrix in the second liquid storage chamber 220 is reduced, and the liquid aerosol matrix directly filled in the second liquid storage chamber 220 is reduced, thereby further reducing the risk of leakage. The liquid storage component 25 and the mist component 30 can always maintain a sufficiently large contact area, so that the atomization component 30 can be supplied with liquid more comprehensively and sufficiently, and the problem of insufficient liquid supply to the atomization component 30 due to a drop in the liquid level can be effectively eliminated.

[0069] Combined with reference Figure 3 and Figure 5 The first base 13 is also provided with a liquid injection hole 133 connected to the first liquid storage chamber 120. The liquid column 221 on the second shell 22 can be inserted into the liquid injection hole 133 to connect the first liquid storage chamber 120 and the second liquid storage chamber 220, so that the second liquid storage chamber 220 can replenish the first liquid storage chamber 120 with liquid in time.

[0070] See also Figure 2 , Figure 3 , Figure 5 and Figure 6 ,in Figure 6 yes Figure 3 The schematic diagrams of the structure of the liquid filling plug in the liquid storage tank are shown in two states (a) and (b), wherein (a) represents the state where the plug column is separated from the elastic tube, and (b) represents the state where the plug column is inserted into the elastic tube.

[0071] In this embodiment, the liquid storage tank 10 also includes a liquid injection plug 15, which includes an elastic tube 151 and a plug column 152 that are flexibly connected to each other. The elastic tube 151 is embedded in the liquid injection hole 133, and the plug column 152 is used to be plugged into the elastic tube 151, so that the first liquid storage chamber 120 becomes a liquid storage space isolated from the outside.

[0072] Among them, Figure 3 and Figure 6 As shown in (b), when the atomizing liquid tank 20 and the liquid storage tank 10 are in a separated state, the plug 152 is inserted into the elastic tube 151 to block the liquid injection hole 133; Figure 2 and Figure 6 As shown in (a), when the atomizing liquid tank 20 and the liquid storage tank 10 are in a connected state, the liquid-passing column 221 is inserted into the elastic tube 151 and the plug column 152 is separated from the elastic tube 151, thereby connecting the first liquid storage chamber 120.

[0073] like Figure 3As shown, before the liquid storage tank 10 is connected to the atomizing liquid tank 20, the aerosol matrix is ​​stored in the first liquid storage cavity 120 thereof, and the injection hole 133 is blocked by the injection plug 15, so that the liquid storage tank 10 can be transported as an independent device. Due to the blocking of the injection plug 15, the aerosol matrix in the liquid storage tank 10 can be well preserved.

[0074] During transportation, the atomized liquid tank 20 can also be sealed separately, for example, by blocking the liquid column 221 to seal the second liquid storage chamber 220, so that when the liquid storage tank 10 and the atomized liquid tank 20 are transported in a separated state, leakage can be effectively prevented.

[0075] like Figure 2 As shown, when the user needs to use it, the liquid storage tank 10 can be installed on the atomizing liquid tank 20, the liquid passing column 221 can be correspondingly inserted into the elastic tube 151, and the plug column 152 can be separated from the elastic tube 151, thereby connecting the first liquid storage chamber 120 and the second liquid storage chamber 220.

[0076] Before use, the liquid storage tank 10 and the atomized liquid storage tank 20 can be packaged independently. When needed, the liquid storage tank 10 and the atomized liquid storage tank 20 are connected to communicate with the first liquid storage cavity 120 and the second liquid storage cavity 220 .

[0077] The liquid injection plug 15 is made of elastic material, and the plug column 152 is inserted into the elastic tube 151, which can achieve good sealing of the liquid injection hole 133; and after being lifted up by the liquid passing column 221, the liquid passing column 221 can also form a sealing structure with the elastic tube 151 to avoid leakage.

[0078] See also Figure 6 In this embodiment, the liquid injection plug 15 includes an elastic portion 153 connected between the elastic tube 151 and the plug column 152. The elastic portion 153 is used to rebound and stretch when the plug column 152 is separated from the elastic tube 151, so that the plug column 152 is away from the elastic tube 151, thereby avoiding blocking the liquid hole of the elastic tube 151, so as to facilitate the first liquid storage chamber 120 to supply liquid to the second liquid storage chamber 220.

[0079] The elastic portion 153 is normally stretched so that the plug post 152 is kept away from the elastic tube 151, thereby avoiding blocking the liquid hole of the elastic tube 151. When the plug post 152 is inserted into the elastic tube 151, the elastic portion 153 will be folded. Therefore, after the plug post 152 is separated from the elastic tube 151, the folded elastic portion 153 will return to the stretched state and drive the plug post 152 away from the elastic tube 151.

[0080] Furthermore, a plurality of convex rings 154 are provided on the inner wall surface of the elastic tube 151 or the outer wall surface of the plug post 152 . The thickness of the convex rings 154 is 0.2-0.6 mm.

[0081] The number of the convex rings 154 can be two, three or four, etc. By providing a plurality of convex rings 154 and limiting the thickness of the convex rings 154 to 0.2-0.6 mm, the sealing properties and friction properties between the elastic tube 151 and the plug column 152 can be uniformed to take into account both the sealing effect and the assembly effect therebetween.

[0082] See also Figure 2 and Figure 3 The end surface of the first base 13 facing the first liquid storage chamber 120 is provided with a liquid collecting groove 134 connected to the liquid injection hole 133, and the end of the liquid injection hole 133 is formed with a retaining edge 135 for stopping the elastic tube 151, so that the elastic tube 151 is lower than the end surface of the first base 13. The retaining edge 135 can stop the elastic tube 151 to prevent the elastic tube 151 from sliding into the first liquid storage chamber 120. The elastic part 153 and at least part of the plug column 152 are located in the liquid collecting groove 134.

[0083] The liquid collecting tank 134 is relatively located at the bottom of the first liquid storage chamber 120 , and is easy to collect aerosol matrix, thereby avoiding waste caused by excessive aerosol matrix remaining in the first liquid storage chamber 120 .

[0084] In addition, the liquid collecting groove 134 can also accommodate the stretched elastic portion 153 and part of the plug column 152 to reduce the space occupied by the elastic portion 153 and the plug column 152 in the first liquid storage chamber 120 , thereby increasing the effective capacity of the first liquid storage chamber 120 .

[0085] In this embodiment, a plurality of groups of liquid injection holes 133, liquid collecting grooves 134 and liquid injection plugs 15 are evenly distributed along the circumferential direction on the first base 13, and a corresponding number of liquid passing columns 221 are also provided on the second shell 22, so as to satisfy the all-round liquid supply to the second liquid storage chamber 220 under various different tilting postures by evenly distributing the plurality of groups of liquid injection holes 133, liquid collecting grooves 134 and liquid injection plugs 15.

[0086] See also Figure 2 , Figure 3 and Figure 5 The insertion tube 222 is inserted into the bell mouth 108 through the through hole 140 on the fixed cover 14, and forms a first liquid suction port 104 between the bell mouth 108 and the wall surface, and the first channel 106 and the second channel 107 are relatively disconnected. The condensed liquid on the wall surface of the second channel 107 cannot flow directly along the wall surface toward the suction nozzle 121 under the action of suction. The condensed liquid will enter the first liquid suction port 104 after encountering the first liquid suction port 104 in the upward flow structure.

[0087] like Figure 2As shown, due to the stop limit of the end face of the second shell 22 and the length limitation of the insertion tube 222, a first liquid suction port 104 is formed between the end of the insertion tube 222 and the wall of the bell mouth 108, wherein the end face of the insertion tube 222 facing the bell mouth 108 is provided with an air hole 223 and a protrusion 224 arranged around the air hole 223, the air hole 223 is connected to the bell mouth 108, the outer diameter of the protrusion 224 is smaller than the maximum inner diameter of the bell mouth 108, and the first liquid suction port 104 is formed between the protrusion 224 and the end face of the insertion tube 222 and the inner wall of the bell mouth 108.

[0088] like Figure 5 As shown, the insertion tube 222 is a tube structure, and one end of the atomizer assembly 30 is sleeved in the insertion tube 222. An air hole 223 is provided on the end surface of the insertion tube 222. The diameter of the air hole 223 is smaller than the inner diameter of the tube body in the insertion tube 222, and an annular protrusion 224 is provided around the edge of the air hole 223. The outer diameter of the protrusion 224 is smaller than the maximum inner diameter of the bell mouth 108, that is, smaller than the inner diameter of the large end of the bell mouth 108, so that the inner wall surface of the bell mouth 108 can drain the liquid to the outside of the air hole 223 and the protrusion 224, and the protrusion 224 can also block the liquid from flowing from the outside to the air hole 223, thereby effectively preventing the condensate from flowing back into the atomizer assembly 30.

[0089] The connection relationship between the liquid storage tank 10 and the atomizing liquid tank 20 can be realized by the connection relationship between the liquid passing column 221 and the liquid injection hole 133; alternatively, the liquid injection plug 15 is installed on the liquid injection hole 133, that is, the elastic tube 151 is installed in the liquid injection hole 133, then the liquid passing column 221 is connected to the elastic tube 151, and the connection relationship between the liquid storage tank 10 and the atomizing liquid tank 20 can be realized.

[0090] Further, see Figure 2 The insertion tube 222 passes through the through hole 140 and is buckled on the fixed cover 14, further strengthening the connection relationship between the liquid storage tank 10 and the atomizing liquid tank 20 to achieve the child lock function, preventing children from separating the liquid storage tank 10 and the atomizing liquid tank 20 due to misoperation, thereby causing the aerosol matrix in the liquid storage tank 10 or the atomizing liquid tank 20 to leak. The leakage not only causes waste but may also enter sensitive parts such as children's eyes. Therefore, the locking achieved between the insertion tube 222 and the fixed cover 14 can prevent children from easily disassembling and separating the liquid storage tank 10 and the atomizing liquid tank 20, thereby avoiding the potential risks caused by this.

[0091] Optionally, the insertion tube 222 is buckled on the through hole 140 . For example, a protruding structure is provided on the side wall of the insertion tube 222 . After passing through the through hole 140 , the protruding structure can be reversely stopped on the through hole 140 .

[0092] See also Figure 2 Zhihe Figure 7 , Figure 7 yes Figure 3 Schematic diagram of the structure of the fixed cover in the liquid storage tank shown.

[0093] In this embodiment, the fixed cover 14 includes a cover body 142 and an embedded tube body 144. The cover body 142 is provided with a through hole 140 and a through hole 141 corresponding to the injection hole 133. The cover body 142 covers the first shell 12 and the first base 13. The embedded tube body 144 is connected to the edge of the through hole 140 and extends toward the first base 13. The outer wall surface of the insertion tube 222 is provided with a flange 227, and the flange 227 is buckled on the end of the embedded tube body 144.

[0094] The fixed cover 14 is a metal cover, which can be made of stainless steel, aluminum alloy or copper alloy by stamping process. The metal cover has high mechanical strength and rigidity, and can withstand large mechanical stress, so as to correct the end shape of the first shell 12 and the first base 13, and reduce the risk of failure of the sealing structure between the first shell 12 and / or the first base 13 due to deformation of the end shape of the first shell 12 and / or the first base 13. In addition, the production and processing cost of the metal cover is also low. Under the above requirements, its thickness is set to be thin, and it can provide good support for the first shell 12 and the first base 13 to prevent deformation, and can also provide sufficient strength to connect with the insertion tube 222 on the second shell 22.

[0095] In this embodiment, the liquid storage tank 10 is a replaceable component, and can be replaced after the aerosol matrix therein is consumed. During replacement, a certain force is applied to separate the liquid storage tank 10 and the atomizing liquid tank 20, which will destroy the structure of the fixed cover 14, and the replaced liquid storage tank 10 is waste. The new liquid storage tank 10 is then connected to the atomizing liquid tank 20, and the fixed cover 14 in the new liquid storage tank 10 is connected to the insertion tube 222 on the second shell 22 to form a child lock structure again, that is, the child lock structure can prevent children from separating the liquid storage tank 10 and the atomizing liquid tank 20, and the child lock structure can also be destroyed under the force of an adult to separate the liquid storage tank 10 and the atomizing liquid tank 20.

[0096] The cover body 142 covers the first shell 12 and the first base 13, and covers the accommodating groove 130 on the first base 13. The cover body 142 also abuts against one end of the liquid injection hole 133, and the embedded tube body 144 is connected to the edge of the through hole 140 and extends toward the first base 13, so that the first base 13 and the fixed cover 14 define a first liquid suction chamber 102, and the first liquid suction chamber 102 is connected to the ventilation pipe 122 in the first shell 12.

[0097] The cover body 142 specifically abuts against one end of the tube wall of the liquid injection hole 133, and the liquid column 221 is also inserted into the elastic tube 151 through the through hole 141, thereby being equivalent to cooperating to block the through hole 141, thereby preventing the liquid in the first liquid absorption chamber 102 and the first liquid absorption member 11 from leaking from the through hole 141.

[0098] The space defined between the embedded tube body 144 and the cover body 142 can accommodate and fix the position of the first liquid absorbent member 11 . The embedded tube body 144 extends toward the first base 13 to form a barrier wall to prevent liquid from leaking from the through hole 140 .

[0099] Specifically, the embedded tube body 144 is spaced apart from the bell mouth 108 and is located below the bell mouth 108 to form a gap, so that the first liquid suction chamber 102 is connected to the ventilation tube 122 through the bell mouth 108, and the flange 227 on the insertion tube 222 is also located at the gap, so as to be buckled with the end of the embedded tube body 144, that is, the gap also forms a connection structure that cooperates with the flange 227.

[0100] The port diameter of the embedded tube body 144 away from the through hole 140 is smaller than the diameter of the through hole 140, thereby forming a closed setting, that is, the aperture of the embedded tube body 144 is in a contracted shape from one end of the through hole 140 to the other end; the flange 227 on the outer wall of the insertion tube 222 can pass through the through hole 140 and be buckled on the end of the embedded tube body 144 away from the through hole 140 to prevent the insertion tube 222 from being disengaged relative to the embedded tube body 144.

[0101] In other words, when the flange 227 is buckled onto the end of the embedded tube 144 away from the through hole 140 , the end of the embedded tube 144 is also locked onto the insertion tube 222 to further enhance the connection strength between them and improve the structural stability of the child lock structure.

[0102] The cover body 142 includes an annular wall portion 145 and an end face portion 146, the annular wall portion 145 is vertically connected to the edge of the end face portion 146, and the end face portion 146 is provided with a through hole 140 and a through hole 141; the side wall of the injection hole 133 and the side wall of the first base 13 have a common side wall portion 136, and the outer wall surface of the first shell 12 is provided with a plurality of first buckles 124 distributed along the circumferential direction, and the first buckle 124 is at least arranged corresponding to the common side wall portion 136; the annular wall portion 145 is provided with a second buckle 147 corresponding to the first buckle 124, and the second buckle 147 is buckled with the first buckle 124, so that the end face portion 146 can be tightened so that the end face portion 146 abuts against one end of the injection hole 133.

[0103] The end face portion 146 is flat, and the annular wall portion 145 is annular and relatively arranged around the embedded tube body 144; the injection hole 133 is arranged relatively close to the edge of the first base 13, so that there is a common side wall portion 136 shared with the side wall of the first base 13. This arrangement can enhance the structural strength of the injection hole 133, and the connection relationship between the annular wall portion 145 and the first shell 12 can provide a certain pulling force so that the end face portion 146 can better abut against one end of the injection hole 133 to avoid leakage from the through hole 141.

[0104] For example, the number of the injection holes 133 can be two, and the number of the first clips 124 can be four, wherein the two first clips 124 are arranged corresponding to the common side wall portion 136 of the injection holes 133, the number of the second clips 147 is also four and their positions correspond to the first clips 124, wherein the two second clips 147 are arranged on the corresponding common side wall portion 136.

[0105] like Figure 4 As shown, the outer wall surface of the first housing 12 is further provided with a guide groove 126, the guide groove 126 is provided corresponding to the common side wall portion 136, and the bottom wall of the guide groove 126 is provided with a first buckle 124; Figure 7 As shown, the annular wall portion 145 is provided with a guide portion 148 that slidably cooperates with the guide groove 126 , and a second buckle 147 is provided on the guide portion 148 .

[0106] The cooperation between the guide groove 126 and the guide portion 148 can locate the position of the fixed cover 14. At the same time, the sliding cooperation can effectively improve the assembly efficiency between the fixed cover 14 and the first shell 12, so that the through hole 141 can be easily aligned with the injection hole 133, and the embedded tube body 144 can be aligned with the bell mouth 108.

[0107] See also Figure 5 The inner wall surface of the second shell 22 is provided with a ventilation groove 225 connecting the insertion tube 222 and the liquid-passing column 221. A second gap 226 is formed between the outer wall surface of the atomizer assembly 10 and the inner wall surface of the insertion tube 222. The ventilation groove 25 is connected to the second gap 226. The second gap 226 is connected to the channel in the atomizer assembly 30. Then, the second gap 226, the ventilation groove 225 and the liquid-passing column 221 constitute a ventilation channel to replenish air in time when the air pressure in the first liquid storage chamber 120 or the second liquid storage chamber 220 is unbalanced. That is, the ventilation channel can replenish air to the first liquid storage chamber 120 and the second liquid storage chamber 220 to avoid poor liquid flow due to imbalance in the air pressure in the chamber.

[0108] The bottom cover 24 is connected to the second base 23 and the second housing 22, and a second liquid absorption chamber 220 is formed between the bottom cover 24 and the second base 23. The second liquid absorption member 21 is accommodated in the second liquid absorption chamber 220. When the leaked liquid or condensed liquid in the channel defined by the atomizing assembly 30 flows downward, it can flow to the second liquid absorption chamber 220 through the second liquid absorption port 105 and be absorbed by the second liquid absorption member 21.

[0109] The bottom cover 24 is provided with an air intake column (not shown) offset relative to the second liquid suction port 220. The air intake column is a tube structure with an air intake hole at the top thereof. The air intake column protrudes from the bottom wall of the bottom cover 24, thereby preventing the liquid on the bottom wall of the bottom cover 24 from leaking out from the air intake column. The second liquid suction member 21 is arranged around the air intake column, and the air intake column is connected to the second liquid suction port 105, so that after the liquid comes down from the second liquid suction port 105, it is blocked by the air intake column and avoids leaking from the air intake hole, but can flow to the second liquid suction member 21, thereby effectively preventing leakage.

[0110] Different from the prior art, the present application discloses an atomizer and an electronic atomization device. By forming a first liquid suction chamber and a second liquid suction chamber connected to the atomization channel on the housing assembly, and respectively setting a first liquid suction port and a second liquid suction port above and below the atomization assembly, the condensed liquid and other liquids above the atomization assembly can flow along the tube wall of the atomization channel through the first liquid suction port to the first liquid suction chamber and be absorbed by the first liquid suction member, and the leaked liquid and other liquids below the atomization assembly can flow along the tube wall of the atomization channel through the second liquid suction port to the second liquid suction chamber and be absorbed by the second liquid suction member, thereby being able to effectively eliminate various types of liquids in the atomization channel, avoiding the risk of taste degradation or damage to the host due to the presence of condensed liquid or leaked liquid, and being able to effectively improve the quality of the atomizer.

[0111] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
