[0002] Electronic atomizing devices have become integrated into daily life, and more and more users have become accustomed to using them.

[0003] Electronic atomizing devices include atomizers. Currently, many atomizers on the market leak during transportation. For example, during transportation, the atomizer may be exposed to high or low temperatures or even high altitude and low pressure. As a result, the liquid inside the atomizer may be affected by environmental changes, causing the sealing ring to fall off or the bottom cap to expand, resulting in oil leakage. Therefore, solving the problem of oil leakage caused by environmental changes is an urgent issue to be addressed in the industry. Utility Model Content

[0004] This application mainly provides a liquid storage tank, an atomizer, and an electronic atomizing device to solve the problem of liquid leakage caused by extreme environmental factors in the atomizer.

[0010] The sidewall of the injection hole and the sidewall of the first base share a common sidewall portion. The outer wall surface of the first housing is provided with a plurality of first buckles distributed circumferentially. The first buckles are provided at least corresponding to the common sidewall portion.

[0011] The annular wall portion is provided with a second buckle corresponding to the first buckle. The second buckle is engaged with the first buckle, thereby tightening the end face portion so that the end face portion abuts against one end of the injection hole.

[0012] In some embodiments, the outer wall surface of the first housing is further provided with a guide groove, the guide groove being provided corresponding to the common side wall portion, and the bottom wall of the guide groove being provided with the first buckle;

The atomizer includes: a liquid storage chamber as described above; an atomizing liquid chamber including a second outer shell and a second base, the second base being connected to the second outer shell and defining a second liquid storage cavity, the second outer shell being provided with a liquid-passing column and an insertion tube, the liquid-passing column communicating with the second liquid storage cavity;

[0016] The liquid-conducting column is inserted into the injection hole, the insertion tube passes through the through hole and connects to the embedded tube body, and is connected to the vent tube.

[0017] In some embodiments, the diameter of the port at the end of the embedded tube furthest from the via is smaller than the diameter of the via;

[0032] This application provides an electronic atomizing device 300, see reference. Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the electronic atomizing device provided in this application.

[0033] The electronic atomizing device 300 includes a main unit 200 and an atomizer 100. The main unit 200 is connected to the atomizer 100 and supplies power to the atomizer 100.

[0034] The electronic atomizing device 300 can be used to atomize aerosol matrices such as e-liquid, medicinal liquid, or nutrient solution, that is, to atomize liquid aerosol matrices into aerosols for users to inhale. The main unit 200 can be detachably connected to the atomizer 100 and supply power to the atomizer 100, thus allowing the atomizer 100 to be replaced; alternatively, the main unit 200 and the atomizer 100 can be integrated into one unit and supply power to the atomizer 100. The atomizer 100 stores and atomizes the aerosol matrix to form an aerosol for the user to inhale.

[0035] The main unit 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 the status information of the atomizer 100 and control the power supply to the atomizer 100 based on the identified status information.

[0036] See also Figure 1 and Figure 2 ,in Figure 2 yes Figure 1 A schematic cross-sectional view of an embodiment of the atomizer in the electronic atomizing device shown.

[0037] like Figure 1 As shown, the atomizer 100 includes a housing assembly 1 and an atomizing assembly 30. The housing assembly 1 has an atomizing channel 101 and forms a first liquid absorption chamber 102 and a second liquid absorption chamber 103 spaced apart along the axis of the atomizing channel 101. The first liquid absorption chamber 102 and the second liquid absorption chamber 103 are both connected to the atomizing channel 101. The atomizing assembly 30 is disposed in the atomizing channel 101 and is used to absorb liquid and generate an aerosol matrix in the atomizing channel 101. A first liquid absorption element 11 is disposed in the first liquid absorption chamber 102, and a second liquid absorption element 21 is disposed in the second liquid absorption chamber 103. The first liquid absorption port 104, which connects the atomizing channel 101 and the first liquid absorption chamber 102, is located above the atomizing assembly 30, and the second liquid absorption port 105, which connects the atomizing channel 101 and the second liquid absorption chamber 103, is located below the atomizing assembly 30.

[0038] The housing assembly 1 has a liquid storage chamber. The atomizing assembly 30 draws liquid from the liquid storage chamber and generates aerosol in the atomizing channel 101. The atomizing channel 101 passes through the liquid storage chamber. The first liquid suction chamber 102 and the second liquid suction chamber 103 are both isolated from the liquid storage chamber. The first liquid suction element 11 located in the first liquid suction chamber 102 and the second liquid suction element 21 located in the second liquid suction chamber 103 are used to absorb the condensate generated by aerosol condensation, large particles of aerosol matrix that are not completely atomized, and some possible leakage, thereby preventing these liquids from being accidentally inhaled into the mouth or leaking into the main unit 200.

[0039] The aerosol generated by the atomizing component 30 may condense under certain conditions. For example, the aerosol may condense when it comes into contact with the cooler tube wall, or large aerosol particles that are not fully atomized may easily form aggregated liquid when they come into contact with the tube wall. Due to manufacturing and assembly errors in the atomizer 100, some atomizers 100 may have a high risk of leakage. If the leaked aerosol matrix enters the inlet or flows to the main unit 200, it will have adverse effects.

[0040] If the liquid adsorbed on the wall of the atomizing channel 101 is not removed in time, it may be inhaled into the mouth the next time the atomizer 100 is used, or flow back to the atomizing component 30, resulting in poor aerosol taste when atomized again, or it may leak into the main unit 200, causing the main unit 200 to malfunction.

[0041] In this application, by forming a first liquid absorption chamber 102 and a second liquid absorption chamber 103 connected to the atomization channel 101 on the housing assembly 1, and by providing a first liquid absorption port 104 and a second liquid absorption port 105 above and below the atomization assembly 30 respectively, liquids such as condensate above the atomization assembly 30 can flow along the tube wall of the atomization channel 101 through the first liquid absorption port 104 to the first liquid absorption chamber 102 and be absorbed by the first liquid absorption element 11, while liquids such as leakage below the atomization assembly 30 can flow along the tube wall of the atomization channel 101 through the second liquid absorption port 105 to the second liquid absorption chamber 103 and be absorbed by the second liquid absorption element 21. This can effectively eliminate various liquids in the atomization channel 101 and avoid the risk of taste deterioration or damage to the main unit 200 caused by existing condensate or leakage.

[0042] The first liquid-absorbing element 11 and the second liquid-absorbing element 21 can be made of materials with excellent liquid absorption capacity, such as cotton fiber or flax fiber. They can absorb liquid and prevent liquid from flowing freely. Therefore, when using the atomizer 100, it can be placed in any position, such as the atomizer 100 is upside down, horizontal or tilted, and the liquid absorbed in the first liquid-absorbing element 11 and the second liquid-absorbing element 21 will not leak out.

[0043] The atomizing channel 101, the first liquid suction chamber 102, and the second liquid suction chamber 103 are defined by the structure within the housing assembly 1. For example, the housing assembly 1 may contain only a single liquid storage chamber that supplies liquid to the atomizing assembly 30.

[0044] In this embodiment, see Figure 2 The housing assembly 1 includes a detachably connected liquid storage chamber 10 and an atomizing liquid chamber 20. The liquid storage chamber 10 is provided with a first liquid storage cavity 120, and the atomizing liquid chamber 20 is provided with a second liquid storage cavity 220. When the liquid storage chamber 10 and the atomizing liquid chamber 20 are connected, the first liquid storage cavity 120 can supply liquid to the second liquid storage cavity 220. 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 the main liquid storage cavity, and the second liquid storage cavity 220 serves as the auxiliary liquid storage cavity. 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 liquid in the second liquid storage cavity 220.

[0045] Furthermore, since the aerosol matrix in the second liquid storage chamber 220 absorbs some of the heat generated by the atomizing component 30 during operation, there is a risk that some of the aerosol matrix will deteriorate due to heat. By setting up 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, thus preventing the diffusion of deteriorated aerosol matrix.

[0046] 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.

[0047] In comparison, the first liquid storage chamber 120 has a large capacity, while the second liquid storage chamber 220 has a small capacity. In the transportation scenario, the liquid storage chamber 10 and the atomizing liquid chamber 20 are in a separate state, that is, the second liquid storage chamber 220 can be empty or carry a small amount of liquid, thus effectively reducing the risk of leakage of the atomizer 100 due to vibration and other factors in the transportation scenario.

[0048] See also Figure 1 and Figure 2 The liquid storage chamber 10 is provided with a first liquid suction chamber 102, and the atomizing liquid chamber 20 is provided with a second liquid suction chamber 103. The atomizing channel 101 includes a first channel 106 disposed in the liquid storage chamber 10 and a second channel 107 disposed in the atomizing liquid chamber 20. The first channel 106 and the second channel 107 define a first liquid suction port 104. The atomizing component 30 is disposed in the second channel 107, and the end of the second channel 107 away from the first channel 106 is connected to the second liquid suction chamber 103.

[0049] The first suction chamber 102 and the second suction chamber 103 are separately arranged in different chambers, which can reduce the structural complexity of the shell assembly 1 and avoid high production costs and complicated assembly processes due to overly complex structures.

[0050] Specifically, the liquid storage chamber 10 is provided with a first liquid storage cavity 120, a first channel 106, and a first suction cavity 102. The first suction cavity 102 is isolated from the first liquid storage cavity 120. The first channel 106 passes through the first liquid storage cavity 120 and connects to the suction nozzle at the top of the liquid storage chamber 10. The first suction cavity 102 and the first channel 106 are connected to one end of the atomizing liquid chamber 20. Therefore, there is no need to provide an additional hole structure on the side wall of the first channel 106 to connect to the first suction cavity 102, which makes the structure of the liquid storage chamber 10 simpler and more reliable. The second suction port 105 is one end 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 structural changes, which also makes the structure of the atomizing liquid chamber 20 simpler and more reliable.

[0051] Furthermore, after the liquid storage chamber 10 is connected to the atomizing liquid chamber 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 by the gap between the first channel 106 and the second channel 107.

[0052] In some embodiments, the first suction port 104 may be defined by the axial gap between the first channel 106 and the second channel 107, or by the radial gap between the first channel 106 and the second channel 107.

[0053] See also Figure 2 and Figure 3 ,in Figure 3 yes Figure 2 A cross-sectional view of the liquid storage chamber in the atomizer shown.

[0054] In this embodiment, the end of the first channel 106 facing the second channel 107 is a flared mouth 108, and the end of the second channel 107 facing the first channel 106 is inserted into the flared mouth 108. The first suction port 104 is the gap formed between the end of the second channel 107 and the wall of the flared mouth 108.

[0055] The small end of the flared mouth 108 has a small diameter, while the large end has a large diameter. The large end faces the second channel 107. The liquid accumulated on the first channel 106 can be guided by the flared mouth 108 to be directed outside the second channel 107 and flow to the first liquid suction member 11, thereby effectively preventing the liquid from flowing back to the second channel 107.

[0056] Optionally, both the first channel 106 and the second channel 107 are straight channels, with the diameter of the first channel 106 being 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.

[0057] See also Figure 3 and Figure 4 ,in Figure 4 yes Figure 3 The diagram shows an exploded view of the liquid storage chamber. In this embodiment, the liquid storage chamber 10 includes a first outer shell 12, a first base 13, and a fixing cover 14. The first base 13 is connected to the port of the first outer shell 12 facing the atomizing liquid chamber 20 and together they define a first liquid storage cavity 120. The side of the first base 13 facing the atomizing liquid chamber 20 is provided with a flared opening 108 and a receiving groove 130 surrounding the flared opening 108. The vent pipe 122 in the first outer shell 12 is connected to the first base 13 and communicates with the flared opening 108. The fixing cover 14 is connected to the first base 13 and seals the receiving groove 130 to form a first liquid absorption cavity 102. The fixing cover 14 is provided with a through hole 140 communicating with the flared opening 108. The second channel 107 communicates with the first channel 106 through the through hole 140. The first channel 106 includes the vent pipe 122 and the flared opening 108 that are connected.

[0058] The first outer shell 12 is provided with a suction nozzle 121 and a vent pipe 122 connected to each other. The first base 13 can be connected to the open end of the first outer shell 12 through a sealing member, or the first base 13 can be glued or fused to the open end, thereby defining a first liquid storage chamber 120 with the first outer shell 12. The vent pipe 122 is connected to the first base 13 and communicates with the flared mouth 108. The vent pipe 122 and the flared mouth 108 constitute the first channel 106.

[0059] Of course, a sealing structure is also provided between the vent pipe 122 and the first base 13 to prevent leakage.

[0060] The first base 13 has a receiving groove 130 around the flared opening 108 on the side opposite to the first liquid storage chamber 120, and the first liquid suction member 11 is housed in the receiving groove 130. A fixing cover 14 is fitted over the open end of the first outer shell 12 and seals the receiving groove 130 to form a first liquid suction chamber 102 that can accommodate the first liquid suction member 11. There is a gap between the edge of the fixing cover 14 facing the flared opening 108 and the wall of the flared opening 108, so that the first liquid suction chamber 102 can be connected to the first channel 106 through the gap, thereby facilitating the flared opening 108 to guide the liquid to the first liquid suction member 11.

[0061] Furthermore, the bottom wall of the accommodating tank 130 is provided with a plurality of condensation adsorption tanks 131, and a first gap 132 is formed between the first liquid suction member 11 and the outer wall surface of the flared mouth 108. The first gap 132 connects the condensation adsorption tank 131 and the first liquid suction port 104.

[0062] Specifically, the first liquid-absorbing element 11 is provided with a through hole corresponding to the horn mouth 108. A first gap 132 is formed between the inner wall surface of the through hole and the outer wall surface of the horn mouth 108. The number of condensation adsorption tanks 131 can be three or four, etc., arranged around the horn mouth 108. The tube wall of the horn mouth 108 protrudes relatively from the condensation adsorption tank 131 and is lower than the top of the receiving tank 130. Thus, when the user uses the atomizer 100 in a normal posture, the openings of the receiving tank 130 and the condensation adsorption tank 131 are both facing downwards. Large aerosol particles gathered in the condensation adsorption tank 131 cannot rise because they are blocked by the bottom of the condensation adsorption tank 131. They are also blocked laterally by the tube wall of the horn mouth 108, so it is difficult for them to flow back into the atomization channel 101 through the first gap 132.

[0063] Through the first gap 132, large aerosol particles that are not fully atomized in the atomization channel 101 can enter the condensation adsorption tank 131 through the first liquid suction port 104 and the condensation adsorption tank 131, thereby accumulating in the condensation adsorption tank 131. After condensing into liquid, they are easily absorbed by the first liquid suction element 11.

[0064] Specifically, in the aerosol components generated by the atomizing component 30 in the atomizing channel 101, some aerosol matrix may not be fully atomized due to certain conditions, resulting in large aerosol particles. These components do not fully express the taste of the aerosol matrix, and filtering them out can optimize the taste of the aerosol. The rising rate of large aerosol particles is relatively slower than that of fully atomized aerosols, so they rise relatively close to the wall of the atomizing channel 101. Therefore, they can enter the condensation adsorption tank 131 through the first liquid suction port 104 and the first gap 132.

[0065] By further forming a condensation adsorption tank 131, the first liquid suction member 11 is covered by the condensation adsorption tank 131, and the condensation adsorption tank 131 is connected to the first liquid suction port 104 through the first gap 132. In this way, large particles of aerosol that are not fully atomized can be collected through the space defined by the condensation adsorption tank 131, which can effectively reduce the content of large particles of aerosol that are not fully atomized in the aerosol generated by atomization, thereby optimizing the taste of aerosol and making the taste of the aerosol absorbed by the user more fully expressed.

[0066] See Figure 5 , Figure 5 yes Figure 2 The diagram shows a cross-sectional view of the atomizing liquid chamber in the atomizer.

[0067] The atomizing liquid chamber 20 includes a second outer shell 22, a second base 23, and a bottom cover 24. The second base 23 is connected to the second outer shell 22 and defines a second liquid storage chamber 220. The second outer shell 22 is provided with a liquid-passing column 221 and an insertion tube 222. The liquid-passing column 221 is used to be inserted 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 intake port 104 is formed between the insertion tube 222 and the wall of the horn 108. The bottom cover 24 is placed on the end of the second base 23 away from the liquid storage chamber 10 and is connected to the second base 23 to form the second liquid intake chamber 220. The second base 232 is provided with a second liquid intake port 105 that connects the atomizing component 30 and the second liquid intake chamber 103.

[0068] The second outer shell 22 has a liquid-passing column 221 and an insertion tube 222 at one end facing the liquid storage tank 10, and the other end of the second outer shell 22 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 outer shell 22 through a sealing element, or the second base 23 can be glued or fused to the open end, thereby defining a second liquid storage chamber 220 with the second outer shell 22. One end of the atomizing component 30 is connected to the second base 23, and the other end is inserted into the insertion tube 222. The second base 32 has a second liquid intake port 105 communicating with the atomizing component 30. The second channel 107 is formed by the insertion tube 222, the channel in the atomizing component 30, and the second liquid intake port 105. The atomizing component 30 and the second base 23 are sealed together to prevent leakage.

[0069] In some embodiments, the second liquid storage chamber 220 can be directly used to store liquid aerosol matrix.

[0070] However, due to errors or defects in materials, processes, or assembly, the sealing structure may fail or its reliability may be reduced, which may lead to leakage at the various connections of the second liquid storage chamber 220. Therefore, this application further provides a liquid storage component 25 in the second liquid storage chamber 220; the atomizing component 30 passes through the liquid storage component 25 and is connected to the insertion tube 222 and the second base 23. The atomizing component 30 is used to draw liquid from the liquid storage component 225 in the second liquid storage chamber 220 and atomize it.

[0071] The liquid storage component 25 can be made of polyester fiber, polypropylene fiber or non-woven fabric, etc. It has high adsorption capacity and uniform adsorption capacity, and can adsorb a certain amount of aerosol matrix. It also has good liquid conduction capacity and stable liquid conduction rate, ensuring that the aerosol matrix can be smoothly transferred to the atomizing component 30.

[0072] By setting up a liquid storage component 25 that can store the aerosol matrix, the fluidity of the aerosol matrix in the second liquid storage chamber 220 is reduced, and the amount of liquid aerosol matrix directly filled in the second liquid storage chamber 220 is reduced, thereby further reducing the risk of leakage. In addition, the liquid storage component 25 and the atomizing component 30 can always maintain a sufficiently large contact area, thereby providing a more comprehensive and sufficient liquid supply to the atomizing component 30, effectively eliminating the problem of insufficient liquid supply to the atomizing component 30 due to a drop in liquid level.

[0073] See also Figure 3 and Figure 5 The first base 13 is also provided with an injection hole 133 that connects to the first liquid storage chamber 120. The liquid column 221 on the second outer shell 22 can be inserted into the 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 in a timely manner.

[0074] See Figure 2 , Figure 3 , Figure 5 and Figure 6 ,in Figure 6 yes Figure 3 The diagram shows two states of the injection plug in the liquid storage tank, namely (a) and (b), where (a) represents the state where the plug is detached from the elastic tube and (b) represents the state where the plug is inserted into the elastic tube.

[0075] In this embodiment, the liquid storage chamber 10 further includes an injection plug 15, which includes an elastic tube 151 and an insertion post 152 that are flexibly connected. The elastic tube 151 is embedded in the injection hole 133, and the insertion post 152 is used to be inserted into the elastic tube 151, so that the first liquid storage chamber 120 becomes a liquid storage space isolated from the outside.

[0076] Among them, such as Figure 3 and Figure 6 As shown in (b), when the atomizing liquid chamber 20 and the storage chamber 10 are in a separated state, the plug 152 is inserted into the elastic tube 151 to seal the injection hole 133; Figure 2 and Figure 6 As shown in (a), when the atomizing liquid chamber 20 and the storage chamber 10 are connected, the liquid column 221 is inserted into the elastic tube 151, and the plug column 152 is disengaged from the elastic tube 151, thereby connecting the first storage chamber 120.

[0077] like Figure 3As shown, before the storage tank 10 is connected to the atomizing liquid tank 20, its first storage chamber 120 stores an aerosol matrix, and the injection hole 133 is blocked by the injection plug 15. Thus, the storage tank 10 can be transported as an independent device. Due to the blocking of the injection plug 15, the aerosol matrix in the storage tank 10 can be well preserved.

[0078] During transportation, the atomizing liquid chamber 20 can also be sealed separately, for example, by blocking the liquid column 221 to seal the second liquid storage chamber 220. Therefore, when the liquid storage chamber 10 and the atomizing liquid chamber 20 are transported in a separate state, leakage can be effectively prevented.

[0079] like Figure 2 As shown, when the user needs to use it, the liquid storage chamber 10 can be installed on the atomizing liquid chamber 20, and the liquid column 221 can be inserted into the elastic tube 151 accordingly, so that the plug column 152 is disengaged from the elastic tube 151, thereby connecting the first liquid storage chamber 120 and the second liquid storage chamber 220.

[0080] Before use, the liquid storage chamber 10 and the atomizing liquid chamber 20 can be independently sealed. When needed, the liquid storage chamber 10 and the atomizing liquid chamber 20 are connected to connect the first liquid storage chamber 120 and the second liquid storage chamber 220.

[0081] The injection plug 15 is made of elastic material. The plug post 152 is inserted into the elastic tube 151 to achieve a good seal for the injection hole 133. After being pushed up by the liquid-conducting column 221, the liquid-conducting column 221 can also form a sealing structure with the elastic tube 151 to avoid leakage.

[0082] See Figure 6 In this embodiment, the injection plug 15 includes an elastic part 153 connected between the elastic tube 151 and the insertion post 152. The elastic part 153 is used to rebound and extend when the insertion post 152 is disengaged from the elastic tube 151, so that the insertion post 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.

[0083] The elastic part 153 is normally extended, keeping the plug 152 away from the elastic tube 151, thereby avoiding blocking the liquid hole of the elastic tube 151. When the plug 152 is inserted into the elastic tube 151, the elastic part 153 will fold. Therefore, after the plug 152 is removed from the elastic tube 151, the folded elastic part 153 will return to the extended state and drive the plug 152 away from the elastic tube 151.

[0084] Furthermore, the inner wall surface of the elastic tube 151 or the outer wall surface of the plug 152 is provided with a plurality of protruding rings 154, the thickness of which is 0.2-0.6mm.

[0085] The number of protruding rings 154 can be two, three, or four, etc. By setting multiple protruding rings 154 and limiting the thickness of the protruding rings 154 to 0.2-0.6mm, the sealing and friction properties between the elastic tube 151 and the plug post 152 can be uniformly balanced, so as to take into account both the sealing effect and the assembly effect between them.

[0086] See Figure 2 and Figure 3 The end face of the first base 13 facing the first liquid storage chamber 120 is provided with a liquid collection groove 134 communicating with the injection hole 133. The end of the injection hole 133 is formed with a stop edge 135 for the elastic tube 151, so that the elastic tube 151 is lower than the end face of the first base 13. The stop 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 post 152 are located in the liquid collection groove 134.

[0087] The liquid collection tank 134 is located at the bottom of the first liquid storage chamber 120. It is easy to collect aerosol matrix, which can avoid waste caused by too much aerosol matrix remaining in the first liquid storage chamber 120.

[0088] In addition, the liquid collection tank 134 can also accommodate the extended elastic part 153 and part of the plug 152, so as to reduce the space occupied by the elastic part 153 and the plug 152 in the first liquid storage chamber 120 and increase the effective capacity of the first liquid storage chamber 120.

[0089] In this embodiment, the first base 13 is provided with a plurality of injection holes 133, liquid collection grooves 134 and injection plugs 15 evenly distributed along the circumference, and the second outer shell 22 is also provided with a corresponding number of liquid columns 221, so as to meet the omnidirectional liquid supply to the second liquid storage chamber 220 under various tilting postures by evenly distributing a plurality of injection holes 133, liquid collection grooves 134 and injection plugs 15.

[0090] See Figure 2 , Figure 3 and Figure 5 The insertion tube 222 is inserted into the flared mouth 108 through the through hole 140 on the fixing cover 14, and forms a first suction port 104 between it and the wall of the flared mouth 108. The first channel 106 and the second channel 107 are also relatively disconnected. The condensate on the wall of the second channel 107 cannot flow directly along the wall to the suction nozzle 121 under the action of suction. When the condensate encounters the first suction port 104 in the upward flow, it will enter the first suction port 104.

[0091] like Figure 2As shown, due to the stop limit of the end face of the second outer 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 surface of the flared mouth 108. The end face of the insertion tube 222 facing the flared 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 flared mouth 108. The outer diameter of the protrusion 224 is smaller than the maximum inner diameter of the flared mouth 108. 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 surface of the flared mouth 108.

[0092] like Figure 5 As shown, the insertion tube 222 is a tube structure, and one end of the atomizing component 30 is fitted inside the insertion tube 222. The end face of the insertion tube 222 is provided with an air hole 223. The diameter of the air hole 223 is smaller than the inner diameter of the tube body in the insertion tube 222. 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 flared mouth 108, that is, smaller than the inner diameter of the large end of the flared mouth 108. Thus, the inner wall of the flared mouth 108 can guide the liquid to the outside of the air hole 223 and the protrusion 224. The protrusion 224 can also block the liquid from flowing from the outside into the air hole 223, thereby effectively preventing the condensate from flowing back into the atomizing component 30.

[0093] The connection between the liquid storage chamber 10 and the atomizing liquid chamber 20 can be achieved by the connection between the liquid-conducting column 221 and the liquid injection hole 133; or, 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-conducting column 221 is connected to the elastic tube 151, which can realize the connection between the liquid storage chamber 10 and the atomizing liquid chamber 20.

[0094] Further, see Figure 2 The insertion tube 222 passes through the through hole 140 and is fastened to the fixing cover 14, further strengthening the connection between the liquid storage tank 10 and the atomizing liquid tank 20 to realize the child lock function, preventing children from separating the liquid storage tank 10 and the atomizing liquid tank 20 due to accidental operation, which could lead to leakage of the aerosol matrix in the liquid storage tank 10 or the atomizing liquid tank 20. Leakage not only causes waste but may also enter sensitive parts such as children's eyes. Therefore, the locking between the insertion tube 222 and the fixing cover 14 can prevent children from easily disassembling and separating the liquid storage tank 10 and the atomizing liquid tank 20, avoiding the potential risks.

[0095] Optionally, the insertion tube 222 is fastened to the through hole 140. For example, the side wall of the insertion tube 222 is provided with a protruding structure, which can be blocked in the opposite direction on the through hole 140 after passing through the through hole 140.

[0096] See Figure 2 Zhihe Figure 7 , Figure 7 yes Figure 3 The diagram shows the structure of the fixed cover in the liquid storage tank.

[0097] In this embodiment, the fixing 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 outer shell 12 and the first base 13. The embedded tube body 144 is connected to the edge of the through hole 140 and extends to the first base 13. The outer wall surface of the insertion tube 222 is provided with a flange 227, which is fastened to the end of the embedded tube body 144.

[0098] The fixing cover 14 is a metal cover, specifically made of materials such as stainless steel, aluminum alloy, or copper alloy by stamping. The metal cover has high mechanical strength and rigidity, capable of withstanding significant mechanical stress. This allows it to correct the end shapes of the first outer shell 12 and the first base 13, reducing the risk of sealing failure due to deformation of the end shapes of the first outer shell 12 and / or the first base 13. Furthermore, the metal cover has lower manufacturing costs, a thinner thickness while meeting the above requirements, and provides good support for the first outer shell 12 and the first base 13 to prevent deformation. It also provides sufficient strength to connect with the insertion tube 222 on the second outer shell 22.

[0099] In this embodiment, the liquid storage tank 10 is a replaceable component. After the aerosol matrix inside is consumed, it can be replaced. During replacement, a certain force is applied to separate the liquid storage tank 10 and the atomizing liquid tank 20, which will damage the structure of the fixing cover 14. The replaced liquid storage tank 10 is a waste. The new liquid storage tank 10 is then connected to the atomizing liquid tank 20. The fixing cover 14 in the new liquid storage tank 10 is connected to the insertion tube 222 on the second outer shell 22, forming 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. Under the force of an adult, the child lock structure can also be destroyed to separate the liquid storage tank 10 and the atomizing liquid tank 20.

[0100] Cover 142 covers the first outer shell 12 and the first base 13, and seals the receiving groove 130 on the first base 13. Cover 142 also abuts against one end of the injection hole 133, and the embedded tube 144 is connected to the edge of the through hole 140 and extends to the first base 13. Thus, the first base 13 and the fixed cover 14 define and form the first liquid suction chamber 102, which is connected to the vent tube 122 in the first outer shell 12.

[0101] The cover 142 is specifically abutted against one end of the wall of the injection hole 133. The liquid column 221 is also inserted into the elastic tube 151 through the through hole 141, which is equivalent to sealing the through hole 141 and preventing the liquid in the first liquid suction chamber 102 and the first liquid suction member 11 from leaking from the through hole 141.

[0102] The space defined between the embedded tube 144 and the cover 142 can accommodate and fix the position of the first liquid suction member 11. The embedded tube 144 extends towards the first base 13 and can form a barrier wall to prevent liquid from leaking from the through hole 140.

[0103] Specifically, the embedded tube 144 is spaced apart from and located below the flared opening 108 to form a gap, so that the first suction chamber 102 is connected to the vent tube 122 through the flared opening 108, and the flange 227 on the insertion tube 222 is also located at this gap, thereby fastening to the end of the embedded tube 144, that is, the gap also forms a connection structure that mates with the flange 227.

[0104] The diameter of the end of the embedded tube 144 away from the through hole 140 is smaller than the diameter of the through hole 140, thus forming a tapered design. That is, the diameter of the embedded tube 144 is tapered 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 fastened to the end of the embedded tube 144 away from the through hole 140 to prevent the insertion tube 222 from disengaging from the embedded tube 144.

[0105] In other words, when the flange 227 is fastened to the end of the embedded tube 144 away from the through hole 140, the port of the embedded tube 144 is also locked to the insertion tube 222 to further enhance the connection strength between them and improve the structural stability of the child lock structure.

[0106] The cover 142 includes an annular wall portion 145 and an end portion 146. The annular wall portion 145 is vertically connected to the edge of the end portion 146. The end 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 share a common side wall portion 136. The outer wall surface of the first outer shell 12 is provided with a plurality of first buckles 124 distributed circumferentially. The first buckles 124 are provided at least 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. The second buckle 147 is engaged with the first buckle 124, thereby tightening the end portion 146 so that the end portion 146 abuts against one end of the injection hole 133.

[0107] The end face 146 is flat, and the annular wall portion 145 is annular and is 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 it shares a common side wall portion 136 with the side wall of the first base 13. This arrangement can enhance the structural strength of the injection hole 133, and the connection between the annular wall portion 145 and the first outer shell 12 can provide a certain tensile force so that the end face 146 can better abut against one end of the injection hole 133, avoiding leakage from the through hole 141.

[0108] For example, there may be two injection holes 133 and four first buckles 124, with two first buckles 124 corresponding to the common sidewall portion 136 of the injection holes 133. There may also be four second buckles 147, with their positions corresponding to the first buckles 124, and two second buckles 147 on the corresponding common sidewall portion 136.

[0109] like Figure 4 As shown, the outer wall surface of the first outer casing 12 is also provided with a guide groove 126, which 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; as Figure 7 As shown, the annular wall portion 145 is provided with a guide portion 148 that slides with the guide groove 126, and a second buckle 147 is provided on the guide portion 148.

[0110] The fit between the guide groove 126 and the guide part 148 can position the fixed cover 14. At the same time, the sliding fit can effectively improve the assembly efficiency between the fixed cover 14 and the first outer shell 12, so that the through hole 141 can be easily aligned with the injection hole 133 and the embedded tube 144 can be aligned with the flared mouth 108.

[0111] See Figure 5 The inner wall of the second outer shell 22 is provided with a ventilation groove 225 that connects the insertion tube 222 and the liquid column 221. A second gap 226 is formed between the outer wall of the atomizing component 10 and the inner wall of the insertion tube 222. The ventilation groove 25 connects to the second gap 226, which is connected to the channel inside the atomizing component 30. Thus, the second gap 226, the ventilation groove 225 and the liquid 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 caused by air pressure imbalance in the chamber.

[0112] The bottom cover 24 connects the second base 23 and the second outer shell 22, and forms a second liquid suction chamber 220 between the bottom cover 24 and the second base 23. The second liquid suction member 21 is housed in the second liquid suction chamber 220. When the leaked liquid or condensate in the channel defined by the atomizing component 30 flows downward, it can flow through the second liquid suction port 105 to the second liquid suction chamber 220 and be absorbed by the second liquid suction member 21.

[0113] The bottom cover 24 is provided with an air inlet column (not shown) offset relative to the second liquid suction port 220. The air inlet column is a tube structure with an air inlet hole at its top. The air inlet column protrudes from the bottom wall of the bottom cover 24, thereby preventing liquid on the bottom wall of the bottom cover 24 from leaking outward from the air inlet column. The second liquid suction member 21 is arranged around the air inlet column. The air inlet 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 inlet column and prevents it from leaking out of the air inlet hole, but can flow to the second liquid suction member 21, which can effectively prevent leakage.

[0114] Unlike existing technologies, this application discloses a liquid storage tank, an atomizer, and an electronic atomizing device. A fixing cover is further provided at the end where the first outer shell and the first base connect. This fixing cover has high mechanical strength and rigidity, providing sufficient force to fasten and correct the first outer shell and the first base, preventing leakage under extreme environments such as high and low temperatures or high altitude and low pressure, thus improving the reliability of the sealing structure between the first outer shell and the first base. Furthermore, by defining the specific structure of the fixing cover and its cooperation with the first base, a first liquid absorption chamber is formed between the first base and the fixing cover, communicating with the vent pipe in the first outer shell. This first liquid absorption chamber is used to collect condensate condensed on the vent pipe, preventing leakage caused by condensate from affecting the taste of the generated aerosol.

[0115] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
