[0029] In the following description, specific details such as specific system structures, techniques, etc. are presented in order to thoroughly understand the embodiments of the present application, but those skilled in the art should understand that the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits and methods are omitted to avoid unnecessary details that hinder the description of the present application.

[0030] In view of the problem of unstable liquid supply caused by the difference between the internal and external pressures of the liquid supplement bottle 200 in the related art, please refer to Figure 1 、 Figure 2 The present application provides an atomization device 1000, which comprises a liquid supplement bottle 200 and an aerosol generating device 101 used in cooperation with the liquid supplement bottle 200.

[0031] Referring to Figure 2 and Figure 3 , the aerosol-generating device 101 mainly comprises an atomizer body 1, a liquid storage member 43, a first liquid guide member 41 and a vent pipe 8. The inside of the atomizer body 1 is provided with a liquid storage cavity 11, a gas exchange cavity 13 and a liquid inlet 12, the liquid storage cavity 11 is used to provide a basis for the liquid storage member 43 to be installed in the atomizer body 1, the gas exchange cavity 13 is in communication with the outside atmosphere, and the liquid inlet 12 is used for the liquid supplement bottle 200 to be detachably connected, when the liquid supplement bottle 200 is connected to the liquid inlet 12, the liquid inlet 12 is in communication with the liquid supplement bottle 200; the liquid storage member 43 is arranged at the liquid storage cavity 11 to store the aerosol substrate; one end of the first liquid guide member 41 is connected with the liquid storage member 43, and the other end thereof is used to be inserted into the liquid supplement bottle 200 to adsorb and conduct the liquid aerosol substrate in the liquid supplement bottle 200 to the liquid storage member 43; one end of the vent pipe 8 is arranged at the gas exchange cavity 13, and the other end of the vent pipe 8 is used to be inserted into the liquid supplement bottle 200 to communicate the inside of the gas exchange cavity 13 and the liquid supplement bottle 200.

[0032] It can be understood that the vent pipe 8 can balance the pressure difference between the inside of the liquid supplement bottle 200 and the outside environment, so as to reduce the probability that the aerosol substrate in the liquid supplement bottle 200 cannot be drawn out or is excessively drawn out. Because during the suction stage, the aerosol substrate in the liquid supplement bottle 200 gradually decreases, and negative pressure is easily formed in the bottle, which causes the aerosol substrate in the bottle to be difficult to be drawn up, especially for the atomization equipment 1000 with the liquid supplement bottle 200 in the upright design, that is, the liquid inlet 12 of the aerosol-generating device 101 is designed above the liquid supplement bottle 200, and the liquid supplement bottle 200 is connected to the liquid inlet 12 in the upright design, the aerosol substrate in the liquid supplement bottle 200 of this type of atomization equipment 1000 is affected by not only the negative pressure but also the gravity, which causes the aerosol substrate to be more difficult to be drawn up. Secondly, when the outside environment is under negative pressure, the aerosol substrate in the liquid supplement bottle 200 is easy to be drawn out, especially when the liquid supplement bottle 200 is inverted, under the action of gravity, the aerosol substrate in the liquid supplement bottle 200 is more easily drawn out. If the pressure difference between the inside of the liquid supplement bottle 200 and the outside environment is balanced through the vent pipe 8, the above-mentioned situation caused by the pressure difference can be avoided. It should be noted that the vent pipe 8 is only used for gas flow and does not have the ability to flow the aerosol substrate. The inverted condition of the liquid supplement bottle 200 can be that the atomization equipment 1000 can be inverted (i.e., the liquid supplement bottle 200 is inverted) during the storage or transportation stage of the atomization equipment 1000, or the liquid supplement bottle 200 can be connected to the liquid inlet 12 of the aerosol-generating device 101 in the inverted design, or other conditions not mentioned herein, which are not limited here.

[0033] Continuing to refer to Figure 2The aerosol-generating device 101 can further include a heating core 2 connected to the liquid storage member 43, which can heat the aerosol substrate. For example, the heating core 2 can heat based on the principle of resistance heating, microwave heating, or other heating methods, which are not limited herein.

[0034] In some embodiments, the aerosol-generating device 101 can further include an air outlet 3 in communication with the outside atmosphere, which is arranged at one end of the aerosol-generating device 101, and the atomized aerosol substrate can be output to the outside through the air outlet 3. The heating core 2 and the air outlet 3 can be arranged on the same straight line to facilitate the output of the atomized aerosol substrate and avoid hindering the flow process; the straight line can be parallel or coincident with the length direction of the atomization device 1000.

[0035] For convenience of description, as shown in Figure 2 , the end of the aerosol-generating device 101 provided with the air outlet 3 is regarded as the proximal end 102, and the end of the aerosol-generating device 101 opposite to the position of the air outlet 3 is regarded as the distal end 103. At the same time, the proximal end 102 is regarded as the top, and the distal end 103 is regarded as the bottom; for the internal structure of the aerosol-generating device 101, the side close to the proximal end 102 can be regarded as the top / end / proximal end 102, and the side close to the distal end 103 can be regarded as the bottom / end / distal end 103.

[0036] First, the structure of the liquid inlet 12 can be referred to Figure 3 , the central axis of the liquid inlet 12 can be arranged parallel / coincident with the length direction of the atomization device 1000. Secondly, the liquid inlet 12 can be sealingly arranged to avoid liquid leakage. In some embodiments, as shown in Figure 3 , a sealing frame 6 is arranged above the liquid inlet 12, and at least part of the structure of the sealing frame 6 can cover the liquid inlet 12 to achieve the sealing effect. Of course, in addition to the above-mentioned way, a sealing member can also be directly arranged at the liquid inlet 12 to block the liquid inlet 12, which is not limited herein. The sealing frame 6 can be provided with a through hole in communication with the liquid inlet 12, so that the first liquid guide member 41 and the air duct 8 can pass through.

[0037] Please continue to refer to Figure 3The inside of the atomizer body 1 can also be provided with a containing position 14 for containing the liquid supplement bottle 200, and the containing position 14 is arranged between the liquid inlet 12 and the distal end 103. The containing position 14 is arranged below the liquid inlet 12, and when the liquid supplement bottle 200 is installed in the containing position 14, the bottle opening of the liquid supplement bottle 200 can be connected with the liquid inlet 12 in a detachable manner such as screwing, buckling, etc. Of course, the inside of the atomizer body 1 does not necessarily need to be provided with the containing position 14, and in some embodiments, the liquid inlet 12 can be arranged to be exposed to the atomizer body 1, and the liquid supplement bottle 200 can be connected with the exposed liquid inlet 12, and at this time the liquid supplement bottle 200 is located outside the atomizer body 1.

[0038] Please see below Figure 4 、 Figure 5 The aerosol generating device 101 can also include a second liquid guide 42 arranged in the atomizer body 1 at a position opposite to the liquid inlet 12, and the second liquid guide 42 is connected with the first liquid guide 41 and the liquid storage 43, respectively. The second liquid guide 42 can function as an aerosol substrate guide, and the aerosol substrate guided out of the liquid supplement bottle 200 by the first liquid guide 41 can flow to the second liquid guide 42, and the second liquid guide 42 can continue to guide the aerosol substrate to the liquid storage 43. Optionally, the second liquid guide 42 can be a liquid guide cotton. It should be noted that the aerosol generating device 101 is not limited to including the second liquid guide 42. In another embodiment, the structure part of the first liquid guide 41 located outside the liquid supplement bottle 200 can be directly connected with the liquid storage 43 in a liquid path, so that the aerosol substrate guided out of the liquid supplement bottle 200 can directly flow to the liquid storage 43.

[0039] Please see below Figure 4 、 Figure 5 The liquid storage 43 can have an elongated structure, and the length direction of the liquid storage 43 can be arranged perpendicular to the width direction of the atomization device 1000. In the length direction of the atomization device 1000, the liquid storage 43 can be located between the gas outlet 3 and the liquid inlet 12, and a part of the structure of the liquid storage 43 can be arranged opposite to the gas outlet 3. At the same time, the part of the structure of the liquid storage 43 is provided with a hollow channel 431 (see Figure 5 The heating chip 2 can be arranged at the hollow channel 431. It can be understood that the liquid storage 43 can not only be used for storing the aerosol substrate, but also can guide the aerosol substrate to the heating chip 2. Optionally, the liquid storage 43 can be a liquid storage cotton.

[0040] Please see below Figure 2The first liquid guide 41 is fixed relative to the atomizer body 1. The first liquid guide 41 can be a strip-shaped structure, one end of which is arranged at the accommodating position 14. When the liquid supplement bottle 200 is connected to the liquid inlet 12, a part of the structure of the first liquid guide 41 is inserted into the liquid supplement bottle 200, and the other end of the first liquid guide 41 extends above the liquid inlet 12 and is connected to the second liquid guide 42. At the same time, the first liquid guide 41 has a capillary effect, which can use the capillary effect to conduct the aerosol substrate in the liquid supplement bottle 200 to the outside of the liquid supplement bottle 200. In some embodiments, the first liquid guide 41 can be a liquid guide rod with a capillary effect.

[0041] It can be understood that in a related technology, the aerosol substrate in the upright liquid supplement bottle 200 is drawn out of the liquid supplement bottle 200 based on the principle of osmotic pressure, but is affected by gravity, and the osmotic pressure itself is limited (when the concentrations of two places are close, the transmission speed between the two places slows down), so the liquid absorption capacity will decrease significantly as the liquid level decreases. This can cause the liquid supply of the atomization device 1000 to be not timely after being puffed for a number of times, thereby causing a burnt wick, dry burning, and on the other hand, the aerosol substrate at the bottom of the liquid supplement bottle 200 cannot be drawn up, and can only be guided out by tilting the bottle body or inverting the liquid supplement bottle 200, which brings a poor user experience. In another related technology, the aerosol substrate in the liquid supplement bottle 200 is drawn out of the liquid supplement bottle 200 by a pump, but this method requires an additional power source, which is high in cost and requires additional power supply, thereby significantly reducing the total number of puffs of the atomization device 1000. However, in the present application, the aerosol substrate in the liquid supplement bottle 200 is guided out of the liquid supplement bottle 200 by capillary force. This aerosol substrate transmission method is not related to the concentration difference, so the liquid absorption capacity of the first liquid guide 41 does not become worse after the atomization device 1000 is puffed for a number of times. Secondly, since the present application realizes aerosol substrate transmission by the principle of natural phenomena, it does not rely on external energy, so it does not reduce the total number of puffs of the atomization device 1000.

[0042] As shown in Figure 2 , the first liquid guide 41 and the hollow channel 431 of the liquid storage member 43 are arranged in the width direction of the atomization device 1000, and the central axis of the first liquid guide 41 is parallel to the center line of the hollow channel 431.

[0043] Continuing to refer to Figure 2, the vent pipe 8 is relatively fixed in the atomizer body 1. The vent pipe 8 can be a strip-shaped structure and is arranged in parallel with the first liquid guide 41. One end of the vent pipe 8 is arranged at the accommodation position 14, and when the liquid supplement bottle 200 is connected to the liquid inlet 12, a part of the structure of the vent pipe 8 is inserted into the liquid supplement bottle 200, and the other end of the vent pipe 8 can pass through the liquid inlet 12 and extend to the ventilation cavity 13. Alternatively, the bottom end of the vent pipe 8 can be arranged flush with the bottom end of the first liquid guide 41.

[0044] In some embodiments, reference can be made to Figure 2 or Figure 3 On the atomizer body 1, a cover 7 is arranged above the second liquid guide 42, the cover 7 and the atomizer body 1 can jointly define a ventilation cavity 13, and there is a gap between the cover 7 and the atomizer body 1, so that the ventilation cavity 13 and the outside atmosphere are in communication. The top end of the vent pipe 8 can pass through the liquid inlet 12 and the second liquid guide 42 in sequence and extend to the ventilation cavity 13.

[0045] Please refer to the following Figure 4 , Figure 6 , the aerosol generating device 101 can further include a hollow fixing pipe 5, and the first liquid guide 41 and the vent pipe 8 are arranged in the fixing pipe 5. The fixing pipe 5 can protect the first liquid guide 41 and the vent pipe 8, and at the same time, the fixing pipe 5 can limit the aerosol substrate of the liquid supplement bottle 200 to flow into the first liquid guide 41 only from the port of the fixing pipe 5; because if the contact area between the first liquid guide 41 and the aerosol substrate is too large, the aerosol substrate is easy to flow out of the bottle, thereby causing the problem of liquid leakage. Moreover, because the vent pipe 8 can only pass gas, its diameter must be very small, resulting in that the structural strength of the vent pipe 8 is relatively weak. If the vent pipe 8 is arranged in the fixing pipe 5 as shown in Figure 6 , on the one hand, the fixing pipe 5 can prevent the structure outside the fixing pipe 5 from damaging the vent pipe 8, and on the other hand, because the structure of the first liquid guide 41 is relatively soft, it can play a buffering role. Therefore, arranging the first liquid guide 41 and the vent pipe 8 in the fixing pipe 5 can reduce the probability of damage to the vent pipe 8. Of course, the vent pipe 8 is not necessarily arranged in the fixing pipe 5, and the vent pipe 8 can also be inserted into the liquid inlet 12, as long as the two ends of the vent pipe 8 can communicate with the inside of the liquid supplement bottle 200 and the outside environment, respectively.

[0046] As shown in Figure 4As shown, the fixed tube 5 can be an elongated circular tube, of course, it can also be a polygonal tubular structure, such as a square tube, etc., which is not specifically limited herein. The fixed tube 5 is fixedly connected to the atomizer body 1, and one end of the fixed tube 5 is used for being inserted into the liquid supplement bottle 200; and the end face of the end of the fixed tube 5 inserted into the liquid supplement bottle 200 is a beveled port 51, and at least a part of the structure of the first liquid guide 41 and / or at least a part of the structure of the air pipe 8 are exposed outside the fixed tube 5.

[0047] It can be understood that, since the size of the atomization device 1000 is generally small, the aperture of the fixed tube 5 is also small, and if the bottom end port of the fixed tube 5 is a flat port, a liquid film can be formed at the bottom end port of the fixed tube 5, which can prevent the aerosol substrate from flowing into the fixed tube 5. A small part of the structure of the first liquid guide 41 is exposed outside the fixed tube 5, which can appropriately increase the contact area between the first liquid guide 41 and the aerosol substrate, thereby avoiding that the conduction efficiency of the first liquid guide 41 is too low. In some embodiments, the end of the first liquid guide 41 located in the liquid storage cavity 11 can be arranged flush with the distal side 511 of the beveled port 51 of the fixed tube 5 (i.e., the side of the beveled port 51 close to the distal end 103). In addition, the design that a part of the structure of the air pipe 8 is exposed outside the fixed tube 5 can be helpful for the circulation of gas.

[0048] Please see the following Figure 7 , the end of the fixed tube 5 inserted into the liquid supplement bottle 200 is spaced apart from the bottle bottom of the liquid supplement bottle 200 by a distance H, and the distance H ranges from 0 mm to 5 mm.

[0049] It can be understood that, the fixed tube 5 is spaced apart from the bottle bottom of the liquid supplement bottle 200, which can avoid the contact between the fixed tube 5 and the liquid supplement bottle 200, and reduce the risk that the fixed tube 5 pierces the bottle bottom of the liquid supplement bottle 200; on the other hand, the spacing between the first liquid guide 41 and the bottle bottom of the liquid supplement bottle 200 should not be too large, because too large spacing can cause that the aerosol substrate at the bottom of the liquid supplement bottle 200 cannot be guided out.

[0050] Furthermore, if the distance H between the fixed tube 5 and the bottom of the liquid supplement bottle 200 is limited within 5mm, even if the liquid supplement bottle 200 is inverted, the liquid level line will be close to the proximal side 512 of the bevel 51 of the fixed tube 5, i.e. the side of the bevel 51 away from the bottom wall, so that the height difference will not be too large, and the force of the aerosol substrate being pressed towards the second liquid guide 42 will not be too large, so that the aerosol substrate will not be easily led out of the bottle, and the risk of liquid leakage will be reduced. It should be noted here that during the liquid injection stage of the atomization device 1000, the liquid supplement bottle 200 will not be filled to the brim (because the aerosol substrate will be easily squeezed out and leak if it is filled to the brim, so a certain amount of space needs to be left), so when the liquid supplement bottle 200 is inverted, a liquid level line will be formed, which is referred to herein as the inverted liquid level line 201, which can be seen in Figure 7 ; if the distance H between the fixed tube 5 and the bottom of the liquid supplement bottle 200 is limited within 5mm, as shown in Figure 7 , the inverted liquid level line 201 will generally be located between the bottom of the liquid supplement bottle 200 and the proximal side 512 of the bevel 51, so that even if the liquid supplement bottle 200 is inverted, the inverted liquid level line 201 will be close to the proximal side 512 of the bevel 51 of the fixed tube 5, thereby effectively reducing the risk of liquid leakage.

[0051] In some embodiments, the distance H between the fixed tube 5 and the bottom of the liquid supplement bottle 200 is preferably between 1.5mm and 3.5mm. In some other embodiments, the distance H is 2mm.

[0052] Please refer to Figure 2 , part of the structure of the second liquid guide 42 can be embedded in the fixed tube 5 to connect with the first liquid guide 41, and the second liquid guide 42 has another part of the structure extending out of the fixed tube 5 to connect with the liquid storage 43.

[0053] In some embodiments, please refer to Figure 5 , among the liquid storage 43, part of the structure is arranged opposite to the liquid inlet 12, and the liquid storage 43 is provided with an embedding position 432 (please refer to Figure 5 ) at the part of the structure. The second liquid guide 42 can be installed at the structure part of the fixed tube 5 extending out of the liquid supplement bottle 200 by interference fit, and the structure part of the fixed tube 5 can extend into the liquid storage 43 through the embedding position 432, and the second liquid guide 42 is located in the embedding position 432 of the liquid storage 43 and is clamped at the embedding position 432.

[0054] As shown in Figure 5As shown, the second liquid guide 42 can include a sleeve part 421 in a cylindrical shape, and an extension part 422 connected to the sleeve part 421. The sleeve part can be sleeved on the outer periphery of the first liquid guide 41, and is arranged between the fixed tube 5 and the first liquid guide 41. The fixed tube 5 is provided with a mounting groove 53, and the extension part 422 can pass through the mounting groove 43 and be embedded in the liquid storage part 43.

[0055] In some embodiments, the fixed tube 5 is further provided with at least one flow port 52 corresponding to the position of the second liquid guide 42, which is in fluid communication with the liquid storage part 43. The aerosol substrate can flow out of the flow port 52, and after flowing out of the flow port 52, it can be absorbed by the liquid storage part 43.

[0056] Continuing to see Figure 5 , the structure part of the fixed tube 5 in which the second liquid guide 42 is embedded is further provided with a protrusion 4211 connected to the first liquid guide 41, which is arranged on the inner side of the sleeve part 421 of the second liquid guide 42, so that the outer peripheral wall surface of the first liquid guide 41 can be in close contact with the inner peripheral wall surface of the sleeve part 421 to ensure that the liquid can be guided. It can be understood that, considering the manufacturing tolerance of the sleeve part 421 and the first liquid guide 41, the sleeve part 421 and the first liquid guide 41 can not be in close contact, which can affect the liquid guiding effect, so a protrusion 4211 is designed to ensure that the first liquid guide 41 and the second liquid guide 42 are in close contact.

[0057] Of course, in this case, the part structure of the second liquid guide 42 does not need to be embedded in the fixed tube 5, and as an optional scheme, the part structure of the first liquid guide 41 can also be selected to protrude out of the fixed tube 5 to be connected to the second liquid guide 42 arranged outside the fixed tube 5.

[0058] In some embodiments, as shown in Figure 4 , the liquid supplement bottle 200 has an elongated structure, the central axis of the fixed tube 5 is parallel to the length direction of the liquid supplement bottle 200, and is perpendicular to the plane in which the liquid inlet 12 is located. The second liquid guide 42 is arranged above the liquid supplement bottle 200, the fixed tube 5 extends to the direction of the second liquid guide 42 and passes through the second liquid guide 42, and is located on the side of the second liquid guide 42 away from the liquid inlet 12. The structure part of the fixed tube 5 located in the second liquid guide 42 is arranged with a plurality of flow ports 52 arranged in a circumferential direction.

[0059] The first liquid guide 41 at the end outside the liquid supplement bottle 200 also penetrates the second liquid guide 42, and is located at the side of the second liquid guide 42 away from the liquid inlet 12. It can be understood that, among the first liquid guide 41, the structural part at the side of the second liquid guide 42 away from the liquid inlet 12 can play a role of storing liquid; on the one hand, the volume of the first liquid guide 41 is increased, and the aerosol substrate capacity that can be carried is increased, so that even if the aerosol substrate in the liquid storage cavity 11 is too much to be guided out, the second liquid guide 42 is not easy to be oversaturated; on the other hand, when the efficiency of guiding out the aerosol substrate in the liquid storage cavity 11 cannot keep up with the consumption efficiency of the heating core 2, the aerosol substrate on the structural part can be provided to the heating core 2, so as to delay the occurrence time of dry burning of the heating core 2, or reduce the probability of dry burning of the heating core 2.

[0060] In addition, the atomization device 1000 further includes a power supply module (not shown in the figure), which is used to generate working power and provide working power for the aerosol generating device 101 through electrical connection with the aerosol generating device 101. For example, the power supply module can be electrically connected with the heating core 2 of the aerosol generating device 101, so that the heating core 2 can be powered to heat.

[0061] It can be understood that the above embodiments only express the preferred embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the patent of the present application; it should be pointed out that, for ordinary skilled persons in the art, the above technical features can be freely combined without departing from the concept of the present application, and some modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, any equivalent transformation and modification within the scope of the claims of the present application shall belong to the scope of the claims of the present application.
