Description

Technical Field

[0001] This application relates to the technical field of atomization, and particularly to an external liquid storage chamber and an atomization device. Background Art

[0002] With the improvement of living quality and environmental protection concept, more and more people are aware of the harm of cigarettes to human health and the pollution of cigarette aerosol to the atmospheric environment, especially the indoor environment. It is imperative to ban smoking and reduce harm. To solve the dependence of smokers on cigarettes, a large-capacity liquid injection atomization device for replacing traditional cigarettes has emerged. In the prior art, the liquid injection atomization device includes an external liquid storage chamber and an atomizer. The atomization liquid is injected into the atomizer as an aerosol generation matrix through the external liquid storage chamber, so that the atomizer can heat and atomize the atomization liquid to generate aerosol for users to inhale.

[0003] Although the above-mentioned type of atomization device has the advantage of a large oil storage capacity, during the use of the above-mentioned type of atomization device, as the atomization liquid in the external liquid storage chamber gradually decreases, the air in the external liquid storage chamber may continuously squeeze the liquid surface of the atomization liquid under the action of negative pressure with a relatively large pressure, causing the atomization liquid to continuously transfer to the liquid storage cotton or atomization core in the atomizer. When the transferred atomization liquid exceeds the maximum liquid locking capacity of the liquid storage cotton or atomization core, the excess atomization liquid will leak from positions such as the atomization chamber, air inlet hole or electrode hole, resulting in a poor user experience. Summary of the Invention

[0004] Based on this, it is necessary to provide an external liquid storage chamber and an atomization device including the external liquid storage chamber that can solve the problem of liquid leakage easily affected by negative pressure during the use of the existing liquid injection atomization device.

One end of the exhaust pipe is inserted into the jack.

[0011] When the atomizer is used in cooperation with the external liquid storage bin, the boss cover wraps at least a part of the atomizer extending into the first liquid storage cavity in the liquid storage space.

[0015] According to another aspect of the present application, an atomization device is provided, including an atomizer and the external liquid storage bin according to any one of the above solutions. The external liquid storage bin can be connected to the atomizer to be used in cooperation with the atomizer. Wherein, the atomizer includes:

[0016] A housing, the housing is provided with an air inlet and an air outlet;

[0017] An atomization assembly, disposed within the housing, the atomization assembly includes an atomization core and an atomization tube, and the atomization core is disposed within the atomization tube;

[0052] An embodiment of the present application provides an external liquid storage chamber and an atomizing device including the external liquid storage chamber. The external liquid storage chamber is used to store the atomizing liquid and continuously supply the atomizing liquid, and the atomizing device is used to heat the atomizing liquid to form an aerosol for the user to inhale.

[0053] Hereinafter, taking the atomizing device as an electronic cigarette and the atomizing liquid as e-liquid as examples, the structure of the atomizing device in the present application will be described. This embodiment is only used as an example for illustration and will not limit the technical scope of the present application. It can be understood that in other embodiments, the atomizing device of the present application is not limited to an electronic cigarette and can also be any other atomizing device that can atomize the atomizing liquid into an aerosol, which is not limited herein.

[0054] Refer to Figures 1 to 3 , Figure 1 which shows the external view schematic diagram of the atomizing device 10 in an embodiment of the present application, Figure 2 which shows the top view of the atomizing device 10, Figure 3A cross-sectional view of the internal structure of the atomizing device 10 is shown. The atomizing device 10 provided by an embodiment of the present application includes an atomizer 100 and an external liquid storage chamber 200. The atomizer 100 is provided with an air inlet 11 and an air outlet 12 that communicate with each other. A first liquid storage cavity 201 for storing atomizing liquid is provided in the external liquid storage chamber 200. The atomizer 100 and the external liquid storage chamber 200 can be connected to each other for cooperative use. When the atomizer 100 and the external liquid storage chamber 200 are used in cooperation, the atomizing liquid in the external liquid storage chamber 200 can be guided to the atomizer 100, and the atomizer 100 can heat the atomizing liquid so that the atomizing liquid can be atomized to generate an aerosol. When the user sucks, external air enters the atomizer 100 from the air inlet 11, is mixed with the aerosol, and is inhaled by the user from the air outlet 12.

[0055] Specifically, referring to Figure 3 and Figure 4 , the atomizer 100 includes a housing 110, an atomizing assembly 120, and a power supply assembly 130. The air inlet 11 and the air outlet 12 are respectively provided at opposite ends of the housing 110 along a vertical direction (the X direction in the figure). The atomizing assembly 120 and the power supply assembly 130 are provided in the housing 110, and the power supply assembly 130 is connected to the atomizing assembly 120. The atomizing assembly 120 is used to heat the atomizing liquid, and the power supply assembly 130 is used to provide electrical energy for the atomizing assembly 120. More specifically, the housing 110 has a first accommodation cavity 110a and a second accommodation cavity 110b that communicate with each other. The first accommodation cavity 110a is located at the top of the second accommodation cavity 110b in the vertical direction. The atomizing assembly 120 is provided in the first accommodation cavity 110a, and the power supply assembly 130 is provided in the second accommodation cavity 110b.

[0056] In a preferred embodiment, as Figure 5 shown, the housing 110 forms an installation position 13 on its outer side. The installation position 13 is located at the top of the second accommodation cavity 110b in the vertical direction and on one side of the first accommodation cavity 110a in the horizontal direction (the Y direction in the figure). The external liquid storage chamber 200 is arranged in the installation position 13, so that the external liquid storage chamber 200 is located on one side of the atomizing assembly 120 in the horizontal direction, and the external liquid storage chamber 200 is also located at the top of the power supply assembly 130 in the vertical direction. Optionally, the installation position 13 is formed by a first surface 110c and a second surface 110d that are perpendicular to each other. The external liquid storage chamber 200 also correspondingly has two surfaces that are perpendicular to each other. One surface is attached to the first surface 110c, and the other surface is attached to the second surface 110d. After the external liquid storage chamber 200 and the atomizer 100 are assembled with each other, the structure is compact and does not occupy space, so as to be convenient to carry and look beautiful.

[0057] In order to conveniently guide the atomizing liquid in the external liquid storage chamber 200 to the atomizer 100, in combination with Figure 5 andFigure 6 As shown, the atomizing device 10 provided by the present application further includes a liquid guiding rod 300. An external liquid storage chamber 200 is provided with a liquid outlet 202 communicating with the first liquid storage chamber 201 on one side corresponding to the first surface 110c. One end of the liquid guiding rod 300 is inserted into the atomizer 100 and connected to the atomizing component 120, and the relatively other end extends out of the atomizer 100 for inserting into the liquid outlet 202 and extending into the first liquid storage chamber 201. The liquid guiding rod 300 is made of a liquid-conducting material. When observed under a microscope and magnified, it can be seen that the liquid guiding rod 300 is provided with a plurality of micropores for the penetration and diversion of the atomizing liquid, so that the atomizing liquid in the first liquid storage chamber 201 can be guided by the liquid guiding rod 300 from one end of the liquid guiding rod 300 to the other end, and then can be guided into the atomizing component 120 and heated and atomized by the atomizing component 120.

[0058] Regarding the structure of the atomizing component 120, please continue to refer to Figure 3 and Figure 6 , in one embodiment, the atomizing component 120 includes an internal liquid storage chamber 121, an atomizing tube 122, and an atomizing core 123. The internal liquid storage chamber 121 includes a chamber body 1211 and a sealing member 1212 provided at the bottom of the chamber body 1211. The inner wall of the chamber body 1211 and one side of the sealing member 1212 together form a second liquid storage chamber 121a. The atomizing tube 122 is provided in the second liquid storage chamber 121a, one end of which is connected to the top of the chamber body 1211, and the relatively other end is connected to the sealing member 1212. A liquid storage cotton 124 made of fiber cotton is provided in the second liquid storage chamber 121a, so it has the functions of guiding liquid and locking liquid. The liquid storage cotton 124 wraps the tube wall of the atomizing tube 122. An air passage 122a is provided in the atomizing tube 122, which penetrates through opposite ends of itself and communicates with the air inlet 11 and the air outlet 12. The atomizing core 123 forms an atomizing chamber 123a, and the atomizing chamber 123a communicates with the air passage 122a. The atomizing tube 122 is further provided with a liquid inlet hole 122b. The atomizing core 123 is electrically connected to the power supply component 130 and is provided at a position in the air passage 122a corresponding to the liquid inlet hole 122b. One end of the liquid guiding rod 300 passes through the chamber body 1211 and contacts the liquid surface, so that one end of the liquid guiding rod 300 is indirectly connected to the atomizing core 123 through the liquid storage cotton 124.

[0059] When the atomizing liquid in the external liquid storage chamber 200 is guided by the liquid guiding rod 300 from one end located in the external liquid storage chamber 200 to one end located in the atomizer 100, the atomizing liquid enters the second liquid storage chamber 121a, is adsorbed by the liquid storage cotton 124, and then the liquid storage cotton 124 guides the atomizing liquid adsorbed on itself to the atomizing core 123 again. The atomizing core 123 heats the atomizing liquid to form an aerosol in the atomizing chamber 123a.

[0060] For the power supply component 130, the power supply component 130 includes a battery, a circuit board, an air flow sensor, etc. The specific structure can refer to the prior art and will not be elaborated here. Of course, the power supply component 130 may not be provided in the atomizer 100, and the atomizer 100 may be externally connected to a power source to supply electrical energy to the atomization core 123, which is not limited herein.

[0061] Refer to Figure 7 , Figure 7 FIG. shows a schematic internal structure diagram of the external liquid storage chamber 200 in an embodiment. In the embodiment shown in the figure, the external liquid storage chamber 200 includes a housing assembly 210, and the first liquid storage chamber is surrounded by the housing assembly 210. Specifically, the housing assembly 210 includes a housing 211 and a sealing seat 212. The liquid outlet 202 is opened on the housing 110. The bottom end of the housing 211 has an opening, and the sealing seat 212 is connected to the housing 211 and closes the opening of the housing 211, so that the inner wall of the housing 211 and one side of the sealing seat 212 together form the first liquid storage cavity 201. Preferably, at least a part of the sealing seat 212 is made of silica gel material, so as to achieve a better sealing effect.

[0062] It can be understood that the atomizer 100 and the external liquid storage chamber 200 can be detachably connected or non-detachably connected. For example, the housing assembly 210 can be detachably connected to the atomizer 100 by means of buckles or magnetic attraction. When the atomizer 100 and the external liquid storage chamber 200 are not connected to each other, the atomizer 100 and the external liquid storage chamber 200 can be transported and shipped separately. For the atomizer 100, the atomization liquid may not be injected into the liquid storage cotton 124 of the atomizer 100 or only a small amount of atomization liquid may be injected, and a sealing plug can also be used to seal one end of the liquid guiding rod 300 extending outside the atomizer 100. And as Figure 8 shown, a sealing film 203 can be provided at the position of the liquid outlet 202 of the external liquid storage chamber 200. The sealing film 203 can be used to close the liquid outlet 202 when the external liquid storage chamber 200 is not used in cooperation with the atomizer 100, so as to prevent the atomization liquid in the first liquid storage cavity 201 from leaking out of the liquid outlet 202 during transportation of the external liquid storage chamber 200. Moreover, the sealing film 203 can also be used to be punctured by the atomizer 100 when the external liquid storage chamber 200 is used in cooperation with the atomizer 100, so that the first liquid storage cavity 201 communicates with the inside of the atomizer 100.

[0063] In order to facilitate puncturing the sealing film 203 when the atomizer 100 is used in cooperation with the external liquid storage chamber 200, in a preferred embodiment, as Figure 5As shown, the atomizer 100 further includes a piercing member 400, which is disposed at the mounting position 13, and is provided with through holes penetrating both ends of the piercing member 400, the liquid guide rod 300 is disposed in the through hole, and the end of the piercing member 400 away from the housing 110 of the atomizer 100 is sharp. In this way, when the external liquid storage tank 200 is connected to the atomizer 100, the piercing member 400 can pierce the sealing film 203, so that the end of the liquid guide member extending outside the atomizer 100 can be conveniently inserted into the liquid outlet 202.

[0064] In this way, through the above-mentioned arrangement, the atomizer 100 and the external liquid storage tank 200 can be transported and shipped separately. When transported and shipped separately, the atomized liquid can be sealed separately in the external liquid storage tank 200, so that the external liquid storage tank 200 has good sealing properties, so that no atomized liquid will leak out of the atomizer 100 and the external liquid storage tank 200. At the same time, since the atomized liquid entering the second liquid storage chamber 121a is locked in the liquid storage cotton 124, the risk of leakage can be further reduced.

[0065] Furthermore, because the external liquid storage tank 200 can be transported separately and is well sealed, liquid atomized liquid can be directly stored in the external liquid storage tank 200, thereby increasing the utilization rate of the atomized liquid and improving the suction experience.

[0066] Furthermore, the liquid guiding rod 300 can also stably and evenly guide the liquid atomized liquid in the first liquid storage chamber 201 into the atomizing core 123 of the atomizing assembly 120, thereby being more conducive to improving the inhalation experience.

[0067] It is understandable that in other embodiments, the end of the liquid-guiding rod 300 extending into the atomizer 100 may also be directly connected to the atomizer core 123, which is not limited here. For example, the atomizer assembly 120 may not be provided with a built-in liquid storage tank 121, and only the atomizer tube 122 and the atomizer core 123 may be provided, and the end of the liquid-guiding rod 300 extending into the atomizer 100 is inserted into the liquid inlet hole 122b, and the atomized liquid is directly introduced into the atomizer core 123 by the liquid-guiding rod 300.

[0068] It is worth noting that, as described in the background technology, as the atomized liquid in the external liquid storage tank 200 is gradually consumed and reduced, the air in the external liquid storage tank 200 may continuously squeeze the liquid surface of the atomized liquid with a large pressure under the action of negative pressure, so that the atomized liquid is continuously transmitted to the liquid storage cotton 124 or the atomization core 123 in the atomizer 100. When the transmitted atomized liquid exceeds the maximum liquid locking capacity of the liquid storage cotton 124 or the atomization core 123, the excess atomized liquid will leak out from the atomization chamber 123a, the air inlet 11 or the electrode hole, resulting in a poor user experience.

[0069] Therefore, to solve this problem, as an improvement to the above embodiments, in some embodiments, please continue to refer to Figure 7 , the external liquid storage chamber 200 further includes an exhaust pipe 220 disposed in the first liquid storage cavity 201. One end of the exhaust pipe 220 is located near the liquid outlet 202, and the other end is located near the cavity wall of the first liquid storage cavity 201. By such an arrangement, when the external liquid storage chamber 200 is used in cooperation with the atomizer 100, the air in the first liquid storage cavity 201 (that is, the air between the liquid level of the atomizing liquid and the cavity wall of the first liquid storage cavity 201) can be guided by the exhaust pipe 220 to near the liquid outlet 202 and discharged from the liquid outlet 202 to the outside of the external liquid storage chamber 200 and then to the external environment, thereby achieving the balance between the air pressure in the first liquid storage cavity 201 and the air pressure of the external environment, avoiding the accumulation of a large amount of air near the liquid level of the atomizing liquid, and thus being able to avoid the air in the first liquid storage cavity 201 continuously squeezing the liquid level of the atomizing liquid with a large pressure, and further being able to avoid the phenomenon of liquid leakage during the process of the atomizing device 10 cooperating with the external liquid storage chamber 200.

[0070] Preferably, in order to better fix the exhaust pipe 220, as shown in Figure 9 and Figure 10 , a boss 2121 is provided on the bottom wall of the first liquid storage cavity 201 (that is, one side surface of the sealing seat 212 for forming the first liquid storage cavity 201) near the liquid outlet 202. Figure 8 and Figure 9 , the boss 2121 is cylindrical, and a ventilation groove 205 communicating with the first liquid storage cavity 201 is provided on the boss 2121. The ventilation groove 205 is opened upward as shown in the figure, and a jack 204 communicating with the ventilation groove 205 is provided on the side wall of the boss 2121. One end of the exhaust pipe 220 is inserted into the jack 204, so that the exhaust pipe 220 can be firmly fixed, and the inner cavity of the exhaust pipe 220 can be communicated with the liquid outlet 202 through the jack 204 and the ventilation groove 205 in sequence. Under the guidance of the exhaust pipe 220 and the ventilation groove 205, the air between the liquid level of the atomizing liquid and the cavity wall of the first liquid storage cavity 201 can flow through the inner cavity of the exhaust pipe 220, the jack 204 and the ventilation groove 205 in sequence and be guided to near the liquid outlet 202. Since the liquid guiding rod 300 itself has a plurality of micropores, air can penetrate into the atomizer 100 through the liquid guiding rod 300 and finally be discharged to the external environment.

[0071] Of course, the fixing method of the exhaust pipe 220 is not limited to this. The exhaust pipe 220 can also be fixed on the cavity wall of the first liquid storage cavity 201 so that the exhaust pipe 220 extends along the cavity wall of the first liquid storage cavity 201, as long as the air between the liquid level of the atomizing liquid and the cavity wall of the first liquid storage cavity 201 can be guided to near the liquid outlet 202.

[0072] Further, in order to ensure that as much air as possible discharged from the ventilation groove 205 can enter the liquid outlet 202, in a preferred embodiment, as Figure 11 shown, the end of the piercing member 400 extending outside the atomizer 100 is provided with an exhaust groove 401 communicating with the through hole. When the atomizer 100 is used in cooperation with an external liquid storage chamber 200, the exhaust groove 401 communicates with the first liquid storage cavity 201. Preferably, the opening of the exhaust groove 401 and the ventilation groove 205 provided on the boss 2121 are oppositely arranged in the vertical direction, so that the inner cavity of the exhaust pipe 220 communicates with the through hole through the exhaust groove 401. In this way, the air discharged from the ventilation groove 205 is directly opposite to the exhaust groove 401, thereby ensuring that as much air as possible can be discharged from the liquid outlet 202 to the outside of the external liquid storage chamber 200, and the boss 2121 can also support the piercing member 400.

[0073] It can be understood that the number of the exhaust pipes 220 is not limited. There can be only one exhaust pipe 220, or there can be several exhaust pipes 220. When the number of the exhaust pipes 220 is several, at least one end of the exhaust pipe 220 far from the liquid outlet 202 is located at a position close to the top wall of the first liquid storage cavity 201, and at least one end of the other exhaust pipe 220 far from the liquid outlet 202 is located at a position close to the side wall of the first liquid storage cavity 201. In this way, during the use of the atomization device 10, regardless of whether the atomization device 10 is placed upright (i.e., the opening of the air outlet 12 is along Figure 2 and Figure 3 the vertical direction upward in Figure 2 and Figure 3 or placed horizontally (i.e., the opening of the air outlet 12 is along

[0074] For example, in the embodiment shown in Figure 12 , the liquid outlet 202 is provided on the side wall of the housing 211. All the exhaust pipes 220 include a first exhaust pipe 221 and a second exhaust pipe 222. Combining Figure 7 and Figure 12As shown, there is one first exhaust pipe 221 and two second exhaust pipes 222. The first exhaust pipe 221 is bent and extended so that the end of the first exhaust pipe 221 away from the liquid outlet 202 is located at a position close to the top wall of the liquid storage cavity; the two second exhaust pipes 222 are symmetrically arranged with the central axis of the boss 2121 as the axis of symmetry, and each second exhaust pipe 222 extends along the radial direction of the boss 2121. One of the second exhaust pipes 222 is also parallel to a part of the first exhaust pipe 221, so that the ends of the two second exhaust pipes 222 away from the liquid outlet 202 are respectively located at positions close to the opposite side walls of the liquid storage cavity.

[0075] Thus, as Figure 12 shown, when the atomizing device 10 is placed upright, the end of the first exhaust pipe 221 away from the liquid outlet 202 is exposed above the liquid level of the atomizing liquid; as Figure 13 and Figure 14 shown, when the atomizing device 10 is placed horizontally and regardless of whether the opening of the air outlet 12 faces Figure 13 the left side in Figure 14 or the right side in

[0076] In some other embodiments, the number of the first exhaust pipe 221 and the second exhaust pipes 222 is not limited. For example, the second exhaust pipes 222 can be an even number, and all the second exhaust pipes 222 are arranged in pairs. The two second exhaust pipes 222 in each pair are symmetrically arranged with the central axis of the boss 2121 as the axis of symmetry. As long as when the atomizing device 10 is placed horizontally or placed at an angle relative to the horizontal plane, the ends of the second exhaust pipes 222 away from the liquid outlet 202 are exposed above the liquid level of the atomizing liquid.

[0077] Referring to Figure 15 、 Figure 16 and Figure 17 In a preferred embodiment, in addition to the boss 2121, a boss cover 2122 is provided at the bottom wall of the first liquid storage cavity 201 (that is, one side surface of the sealing seat 212 for forming the first liquid storage cavity 201) at a position close to the liquid outlet 202. The boss cover 2122 encloses a liquid storage space 206 in the first liquid storage cavity 201, and the boss cover 2122 is provided with a jack 204 communicating with the liquid storage space 206; one end of the exhaust pipe 220 is inserted into the jack 204; combined with Figure 15 and Figure 16As shown, at least a part of the boss 2121 is located in the liquid storage space 206, so that the ventilation groove 205 formed on the boss 2121 communicates with the liquid storage space 206. And a first gap 207 is formed between one side of the boss cover 2122 and the side wall of the first liquid storage cavity 201, and the liquid storage space 206 communicates with the part of the first liquid storage cavity 201 excluding the liquid storage space 206 through the first gap 207. In Figure 17 In the embodiment of, the boss 2121 is composed of two convex pieces 2121a arranged at intervals, and the two convex pieces 2121a jointly form the ventilation groove 205. Of course, the boss 2121 can also be the cylindrical structure mentioned in the previous embodiment, which is not limited here.

[0078] When the atomizer 100 is used in cooperation with the external liquid storage bin 200, the boss cover 2122 wraps at least a part of the piercing member 400 and the liquid guiding rod 300 extending into the first liquid storage cavity 201 in the liquid storage space 206. In this way, with the boss cover 2122, under the barrier of the boss cover 2122, a liquid storage space 206 with a volume much smaller than the volume of the first liquid storage cavity 201 is formed by the boss cover 2122. A small part of the atomized liquid in the first liquid storage cavity 201 can first flow into the liquid storage space 206, so that only a small part of the atomized liquid in the liquid storage space 206 exerts pressure on the end of the liquid guiding rod 300 extending into the first liquid storage cavity 201. Therefore, the pressure of the atomized liquid on the liquid guiding rod 300 can be reduced, and further leakage caused by continuous extrusion of the liquid guiding rod 300 can be avoided.

[0079] It can be understood that for the above embodiments, the boss cover 2122 can open an insertion hole 204 on its top wall or on its side wall, so that the exhaust pipe 220 can be connected to the top wall of the boss cover 2122 or to the side wall of the boss cover 2122. For example Figure 15 and Figure 16 In, only the first exhaust pipe 221 is shown. One end of the first exhaust pipe 221 is connected to the top wall of the boss cover 2122, and the other end extends in the vertical direction to a position close to the top wall of the first liquid storage cavity 201. If there is also a second exhaust pipe 222, one end of the second exhaust pipe 222 can be connected to the side wall of the boss cover 2122 and extend in the horizontal direction, so that the other end extends to a position close to the side wall of the first liquid storage cavity 201.

[0080] It can also be understood that in another embodiment, only the boss cover 2122 can be provided without the boss 2121. When the atomizer 100 is used in cooperation with the external liquid storage bin 200, the boss cover 2122 only wraps at least a part of the piercing member 400 and the liquid guiding rod 300 extending into the first liquid storage cavity 201 in the liquid storage space 206.

[0081] Further, in order to better fix the exhaust pipe 220, refer toFigure 18 , on the basis of the above embodiments, a fixing block 2123 is further provided on the side wall of the first liquid storage chamber 201. A positioning groove 208 matching the diameter of the single exhaust pipe 220 is formed between the fixing block 2123 and the side wall of the first liquid storage chamber 201. The exhaust pipe 220 is clamped in the positioning groove 208, so as to prevent the exhaust pipe 220 from shaking randomly in the first liquid storage chamber 201.

[0082] Furthermore, in terms of the structure of how the air discharged from the exhaust pipe 220 passes through the liquid outlet 202 and is discharged to the external environment, as Figure 19 and Figure 20 shown, the liquid guide rod 300 is provided with a first air guide groove 301. The liquid storage cotton 124 has air guide holes 1241 communicating with the external environment. One end of the first air guide groove 301 extends into the atomizer 100 and communicates with the air guide holes 1241, and the other end communicates with the first liquid storage chamber 201. In this way, the negative pressure generated in the first liquid storage chamber 201 can be communicated with the ambient air pressure through the air guide holes 1241 and the exhaust pipe 220, so as to maintain a balanced state and reduce the risk of liquid leakage caused by pressure imbalance. In the embodiment shown in the figure, the first air guide groove 301 penetrates through the opposite ends of the liquid guide rod 300. Of course, the first air guide groove 301 can also only extend to the middle of the liquid guide rod 300, but as long as it communicates with the air guide holes 1241, it is not limited here.

[0083] On this basis, please continue to refer to Figure 19 and Figure 20 , the atomization assembly 120 further includes an air guide pipe 125. The air guide pipe 125 extends vertically and is wrapped in the liquid storage cotton 124. The air guide holes 1241 penetrate through the opposite ends of the air guide pipe 125 in the vertical direction. The purpose of setting the air guide pipe 125 is that the material of the liquid storage cotton 124 is relatively soft. To prevent the hole walls of the air guide holes 1241 from sticking to each other, setting the air guide pipe 125 can expand the air guide holes 1241, so as to prevent the air guide holes 1241 from being blocked.

[0084] In the specific implementation manner of how the first air guide groove 301 communicates with the air guide holes 1241, the liquid storage cotton 124 is provided with a second air guide groove 1242 communicating with the first air guide groove 301. The second air guide groove 1242 and the air guide holes 1241 both penetrate through the liquid storage cotton 124 and are parallel to each other. A second gap 120a is formed between the top of the liquid storage cotton 124 and the top wall of the built-in liquid storage bin 121. The second air guide groove 1242 and the air guide holes 1241 communicate with each other through the second gap 120a. Of course, it can also be to open another groove in the liquid storage cotton 124, and the first air guide groove 301 and the second air guide groove 1242 communicate with each other through this groove, which is not limited here.

[0085] In the implementation manner of how the air guide holes 1241 communicate with the external environment, in combination with Figure 4 ,Figure 19 and Figure 20 As shown in Figure 20 , an air passage groove 1212a communicating with the external environment can be opened on the built-in liquid storage chamber 121, and the air guide hole 1241 communicates with the air passage groove 1212a. Specifically, the air passage groove 1212a is opened on the seal 1212 and penetrates through the seal 1212; the housing 110 includes a first housing 111 and a second housing 112 that are detachably connected to each other, and a gap 110e communicating with the external environment is formed between the first housing 111 and the second housing 112, and the gap 110e communicates with the air passage groove 1212a.

[0086] From Figure 20 the air flow direction indicated by the dotted arrow in Figure 20 , and combined with Figure 4 it can be seen that the air discharged from the exhaust pipe 220 and the ventilation groove 205 sequentially passes through the first air guide groove 301, the second air guide groove 1242, the second gap 120a formed between the liquid storage cotton 124 and the top wall of the built-in liquid storage chamber 121, the air guide hole 1241, the air passage groove 1212a, and the gap 110e formed between the first housing 111 and the second housing 112 and is discharged to the external environment, or the air inside the first liquid storage chamber 201 itself can pass through the air guide hole 1241, the air passage groove 1212a, and the gap 110e formed between the first housing 111 and the second housing 112 and is discharged to the external environment, so as to achieve the balance of the environmental pressure and the pressures in the first liquid storage chamber 201 and the second liquid storage chamber 121a.

[0087] In other embodiments, holes communicating with the outside can also be opened in the housing 110, and it is also possible to make the holes communicate with the air passage groove 1212a, which is not limited here.

[0088] Thus, it can be seen that the atomizing device 10 provided in this application, by arranging the exhaust pipe 220 in the external liquid storage chamber 200, with one end of the exhaust pipe 220 located near the liquid outlet 202 of the external liquid storage chamber 200 and the other end located near the wall of the first liquid storage chamber 201, can avoid a large amount of air from gathering near the liquid surface of the atomizing liquid. Therefore, it can avoid the air in the first liquid storage chamber 201 from continuously squeezing the liquid surface of the atomizing liquid with a large pressure, and further reduce the risk of liquid leakage to the lowest level, solving the problem that the existing liquid injection type atomizing device 10 is prone to liquid leakage under the influence of negative pressure during use, and greatly improving the user experience.

[0089] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered as the scope described in this specification.

[0090] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patented application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
