Description

Technical Field

[0001] Example embodiments of the present disclosure generally relate to the field of atomization devices, and in particular, to an atomization device and an atomization apparatus. Background Art

[0002] In recent years, the consumer group of atomization devices such as electronic cigarettes has gradually increased in the market, and they are increasingly favored by consumers. At present, mainstream electronic cigarettes on the market are usually equipped with a liquid storage tank to hold the atomization matrix. The atomization matrix in the liquid storage tank is connected to the atomization core fluid to be atomized by the atomization core to form an aerosol. However, since electronic cigarettes may have different tilt angles when in use, when the tilt angle of the electronic cigarette is large, the amount of atomization matrix flowing to the atomization core may be insufficient, resulting in a burnt smell. Summary of the invention

[0003] In a first aspect of the present disclosure, an atomizing device is provided. The atomizing device comprises: an atomizing core for atomizing an atomizing substrate; a first liquid storage tank and a second liquid storage tank, both for accommodating the atomizing substrate, and the atomizing substrate in the first liquid storage tank is fluidically connected to the atomizing core via the second liquid storage tank; and a ventilation channel, airtightly connecting the first liquid storage tank to the external atmosphere to allow gas to enter the first liquid storage tank from the external atmosphere.

The gas entering the first liquid storage tank due to the ventilation is not easy to enter the second liquid storage tank, so that the second liquid storage tank is filled with the atomizing matrix during most of the time period, and can contact the atomizing core even when the atomizing device is tilted, so that the atomizing core remains in a state of being fully infiltrated with the atomizing matrix, thereby avoiding various problems caused by dry burning of the atomizing core, and can reduce the requirements for the use angle of the atomizing device, thereby improving user experience.

[0005] In some embodiments, the atomization device further includes: an isolation component arranged between the first liquid storage tank and the second liquid storage tank to seal the first liquid storage tank and the second liquid storage tank, and includes: at least one liquid channel connecting the first liquid storage tank and the second liquid storage tank.

[0007] In some embodiments, the ventilation channel is arranged on at least one of the tank wall, the isolation component and the atomization seat of the first liquid storage tank.

[0008] In some embodiments, the cross-sectional area of ​​each of the at least one liquid channel is within 1 mm 2 ~9mm 2 within the range.

[0009] In some embodiments, the isolation component also includes an isolation plate, which is sealed and arranged between the first liquid storage tank and the second liquid storage tank; and a ventilation pipe, which extends from the isolation plate in a direction from the first liquid storage tank to the second liquid storage tank, and wherein the atomizer seat also includes a gas circulation channel, which is airtightly connected to the ventilation pipe to form a ventilation channel together with the ventilation pipe.

[0023] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

[0024] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to". The term "based on" should be understood as "based at least in part on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". Other explicit and implicit definitions may be included below. The terms "first", "second", etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.

[0025] As briefly mentioned above, currently, the structure of an atomization device (such as an electronic cigarette) generally includes a liquid storage tank and an atomization core. The liquid storage tank is used to store the atomization matrix, while the atomization core is used to heat the atomization matrix to atomize and form an aerosol.

[0026] However, during the user's use, as the atomized matrix in the liquid storage tank continues to decrease, when the user inhales upside down or lays flat, the atomized matrix flows to one side under the action of gravity, making it difficult to flow to the atomizer core. In this case, the atomizer core will produce a burnt smell during the heating process. This is because the part of the atomizer core that is not fully wetted may be overheated and cause coking. Therefore, for traditional atomization equipment, in order to ensure that the atomization core can be in good contact with the atomization matrix, the user needs to pay attention to the angle requirements of the atomization equipment when inhaling, which will affect the user's experience when using the atomization equipment.

[0027] In order to solve or at least partially solve the above-mentioned problems or other potential problems of the atomizing device of the traditional solution, the embodiment of the present disclosure provides an atomizing device and an atomizing device using the atomizing device. The atomizing device implemented according to the present disclosure uses two liquid storage tanks (hereinafter referred to as the first liquid storage tank and the second liquid storage tank, respectively), and the atomizing matrix in the first liquid storage tank is connected to the atomizing core fluid through the second liquid storage tank, and the ventilation channel is ventilated for the first liquid storage tank. When the remaining amount of the atomizing matrix exceeds the volume of the second liquid storage tank, since the ventilation channel is connected to the first liquid storage tank, the gas in the ventilation channel will not enter the second liquid storage tank, and the atomizing matrix in the second liquid storage tank will not flow due to the different angles of the atomizing device, so that the atomizing matrix of the second liquid storage tank is always in contact with the atomizing core, so that no matter what posture the atomizing device is in during use, the atomizing matrix can fully infiltrate the entire atomizing core, thereby effectively avoiding the burnt smell caused by the atomizing core not being fully infiltrated. That is to say, when the user uses the atomizer device, as long as the remaining amount of the atomizer matrix exceeds the volume of the second liquid storage tank, no matter what position the atomizer device is in, a good suction effect can be obtained, thereby effectively improving the user experience. In addition, the ventilation channel can also effectively ventilate the first liquid storage tank to maintain air pressure balance, thereby improving the reliability of the atomizer device.

[0028] In some embodiments, a traditional liquid storage tank can be divided into a first liquid storage tank and a second liquid storage tank by an isolation component. The isolation component can be a separate component for dividing the liquid storage tank (as will be described below), or it can be a component formed integrally with the liquid storage tank, which will be further described below. The second liquid storage tank is arranged adjacent to the atomization core so that the atomization matrix in the first liquid storage tank is communicated with the atomization core through the second liquid storage tank, that is, the atomization matrix in the second liquid storage tank is directly in contact with the atomization core. At the same time, the ventilation channel directly ventilates the first liquid storage tank to ensure the effective pressure in the first liquid storage tank and the second liquid storage tank and the pressure balance in the two liquid storage tanks. As a result, it is not easy for gas to appear in the second liquid storage tank, that is, at least when the amount of the atomization matrix is ​​greater than the volume in the second liquid storage tank, the atomization matrix in the second liquid storage tank always remains full of oil. In this way, no matter what posture the atomizer device is in, it can ensure that the atomizer matrix in the second liquid storage tank completely soaks the atomizer core, so that the atomizer core will not dry burn and produce a burnt smell, thereby improving the reliability, stability and user-friendliness of the atomizer device.

[0029] The atomizing device according to the embodiment of the present disclosure may include an electronic cigarette, for example, a disposable electronic cigarette. It should be understood that the atomizing device according to the embodiment of the present disclosure may also include a cartridge-changing electronic cigarette, that is, the user can replace the cartridges of different flavors as needed, and the cartridge includes a liquid storage tank (such as the first and second liquid storage tanks to be described in detail below) and an atomizing core. In addition, it should also be understood that the atomizing device according to the embodiment of the present disclosure may also include any other appropriate atomizing device 100 other than the electronic cigarette.

[0030] It should be understood that the "up" and "down" mentioned herein are relative to the direction of gravity, and the direction that is the same as the direction of gravity is "down", and the opposite direction is "up". For the atomizing device 110, for the sake of ease of description, at least some of the embodiments described below will usually be described as an example in which the extension direction of the atomizing device 110 (i.e., the axial direction B) is consistent with the direction of gravity. It should be understood that the situation in which the atomizing device or atomizing device adopts other usage postures is also similar, and will not be described separately below.

[0031] The specific exemplary structure of the atomization device and the atomization equipment according to the embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. Figure 1 The overall structural diagram of the atomization device 100 according to the embodiment of the present disclosure is shown. Figure 2 An exploded view of the atomizing device 100 according to an embodiment of the present disclosure is shown. Figure 3 FIG. 1 is a cross-sectional schematic diagram of an atomization device 100 according to an embodiment of the present disclosure. Figures 1 to 3 As shown, the atomizing device 100 includes an atomizing device 110, a housing 140, and a power supply 120 arranged in the housing 140 for powering the atomizing device 110, which will be described in detail below. The housing 140 can be coupled to the atomizing device 110 in an appropriate manner. A suction nozzle 130 can also be arranged at one end of the atomizing device 110 (for example, an end away from the housing 140). The suction nozzle 130 can be integrally formed with other parts of the atomizing device 110 (for example, a part forming a liquid storage tank), or it can be formed separately and installed on other parts of the atomizing device 110 in a detachable manner. The power supply 120 can include a battery, etc. The power supply 120 and the atomizing device 110 can be arranged to be detachably coupled, so as to form, for example, a cartridge-changing atomizing device 100. When the atomizing device 110 is powered, the atomizing core therein can heat and atomize the liquid atomizing matrix in the second liquid storage tank 116 to produce an aerosol, which will be further described below.

[0032] Figure 4 FIG. 1 is a cross-sectional schematic diagram of an atomization device 110 according to an embodiment of the present disclosure. Figure 3 and Figure 4As shown, the atomization device 110 according to the embodiment of the present disclosure generally includes a first liquid storage tank 115, a second liquid storage tank 116 and a ventilation channel 1125. The first liquid storage tank 115 and the second liquid storage tank 116 are both used to accommodate atomized substrates, and the atomized substrates in the first liquid storage tank 115 are in fluid communication with the atomization core via the second liquid storage tank 116. The ventilation channel 1125 airtightly connects the first liquid storage tank 115 with the external atmosphere, thereby allowing gas to enter the first liquid storage tank 115 from the external atmosphere to ventilate the first liquid storage tank 115.

[0033] In some embodiments, as mentioned above, the first liquid storage tank 115 and the second liquid storage tank 116 can be formed by dividing a liquid storage tank by the isolation component 111. The isolation component 111 is arranged between the first liquid storage tank 115 and the second liquid storage tank 116 to seal the first liquid storage tank 115 and the second liquid storage tank 116, that is, the isolation component 111 isolates the liquid storage tank into the first liquid storage tank 115 and the second liquid storage tank 116. The second liquid storage tank 116 is arranged on one side adjacent to the atomization core so that the atomization matrix therein is in contact with the atomization core. Although the first liquid storage tank 115 and the second liquid storage tank 116 are arranged up and down along the axial direction B in the illustrated exemplary embodiment, it should be understood that as long as the atomization matrix in the second liquid storage tank 116 can maintain contact with the atomization core, the first liquid storage tank 115 and the second liquid storage tank 116 can also be arranged left and right in the radial direction. The concept of the present disclosure will be described below mainly using the exemplary embodiment shown in the figure in which the first liquid storage tank 115 and the second liquid storage tank 116 are arranged along the axial direction B. It should be understood that the situation in which other arrangements of the two liquid storage tanks are adopted is also similar and will not be described separately below.

[0034] In addition, the formation method of the first liquid storage tank 115 and the second liquid storage tank 116 is not limited to the above-mentioned embodiments. Specifically, as long as the first liquid storage tank 115 can be ventilated, and the atomized matrix therein can be connected to the atomization core fluid through the second liquid storage tank 116 by appropriate means, the first liquid storage tank 115 and the second liquid storage tank 116 can also be formed in other ways. For example, in some embodiments, the first liquid storage tank 115 and the second liquid storage tank 116 can also be separately formed liquid storage tanks and assembled together in an appropriate manner, or the first liquid storage tank 115 and the second liquid storage tank 116 can also be divided by a partition formed integrally with the liquid storage tank. . The following will mainly describe the concept of the present disclosure by taking the isolation of the first liquid storage tank 115 and the second liquid storage tank 116 by the isolation component 111 as an example. It should be understood that it is similar for other situations and will not be repeated separately below.

[0035] like Figure 3 and Figure 4As shown, in some embodiments, the first liquid storage tank 115 is connected to the second liquid storage tank 116 through the liquid channel 1124 of the isolation component 111, which will be described in detail below. In some embodiments, the atomization device 110 also includes an atomization seat 114, which is used to accommodate and fix the atomization core. The space formed between the isolation component 111 and the atomization seat 114 is the second liquid storage space, that is, the second liquid storage tank 116. In some embodiments, the isolation component 111 can be integrally formed with the atomization seat 114. When the atomizing device 110 is in working state, the atomizing matrix in the second liquid storage tank 116 is continuously consumed, and the atomizing matrix in the first liquid storage tank 115 can continuously provide replenishment to the second liquid storage tank 116 through the liquid channel 1124, so that the atomizing matrix in the second liquid storage tank 116 can be kept full for most of the time period. Therefore, when the atomizing device 110 is inverted for suction (which can also be understood as suction at a negative angle) or laid flat for suction, the atomizing core arranged in the atomizing seat 114 can fully contact with the atomizing matrix, thereby effectively avoiding the burning smell caused by dry burning.

[0036] From the above description, it can be seen that as long as the atomizing matrix of the second liquid storage tank 116 is always kept full, the atomizing core will not dry burn due to some angle problems such as the tilt of the atomizing device 110. In other words, the smaller the volume of the second liquid storage tank 116, the longer the time period that can avoid the atomizing core from dry burning. Therefore, in order to extend the time that the atomizing core will not dry burn as much as possible to improve the user experience, in some embodiments, the volume of the second liquid storage tank 116 can be greater than the volume of the first liquid storage tank 115.

[0037] As mentioned above, the ventilation channel 1125 can connect the first liquid storage tank 115 and the external atmosphere in an airtight manner, thereby ensuring that air is replenished for the first liquid storage tank 115 when the atomized matrix in the first liquid storage tank 115 is consumed, ensuring the pressure balance between the first liquid storage tank 115 and the second liquid storage tank 116 and the positive pressure state of the entire liquid storage tank, thereby ensuring the reliable output of the atomized matrix and further ensuring the reliability of the atomization device.

[0038] In some embodiments, the ventilation channel 1125 will not leak the atomized matrix in the first liquid storage tank 115 to the outside, which can be achieved by appropriate structures or components. For example, in some embodiments, at least a portion of the ventilation channel 1125 along the extension direction can have a capillary size, thereby only allowing gas to pass without allowing the atomized matrix to flow out. In some embodiments, alternatively or additionally, the atomizing device may also include a one-way valve or the like arranged at an appropriate position in the ventilation channel 1125.

[0039] In some embodiments, the ventilation channel 1125 can connect the first liquid storage tank 115 to the external atmosphere via the atomizer seat 114. For example, in some embodiments, the isolation component 111 may include an isolation plate 1121 and a ventilation tube 1123. In some embodiments, the isolation plate 1121 may also include an isolation sealing silicone 112 at least on the outside, and the circumferential wall of the isolation sealing silicone 112 abuts against the side wall of the first liquid storage tank 115, which is used to provide a sealed isolation between the first liquid storage tank 115 and the second liquid storage tank 116. Of course, in some alternative embodiments, the isolation sealing silicone 112 can also be integrally formed with the isolation plate 1121, that is, the isolation plate 1121 can also be made of an elastic material including a silicone material, which is not specifically limited in the present disclosure. In some embodiments, the isolation plate 1121 also has a smoke channel hole 1126 at the central position, which is used to connect the smoke channel 131 of the suction nozzle 130 to pass through.

[0040] In some embodiments, the ventilation tube 1123 extends from the isolation plate 1121 in a direction from the first liquid storage tank 115 to the second liquid storage tank 116. The internal passage defined by the ventilation tube 1123 forms a part of the ventilation channel 1125. Another part of the ventilation channel 1125 is formed on the atomizer seat 114. Specifically, another part of the ventilation channel 1125 is formed by a gas circulation channel on the atomizer seat 114. The gas circulation channel of the atomizer seat 114 is airtightly connected to the ventilation tube 1123, so that the gas circulation channel and the ventilation tube 1123 together form the ventilation channel 1125. For example, in some embodiments, the ventilation tube 1123 mentioned above extending from the isolation plate 1121 to the atomizer seat 114 is airtightly connected to the opening of the gas circulation channel on the atomizer seat 114 (the ventilation hole 1141 to be mentioned below), so that the first liquid storage tank 115 is ventilated through the gas circulation channel of the atomizer seat 114 and the ventilation tube 1123 of the isolation plate 1121.

[0041] The following will be combined Figure 4 and Figure 5 The specific structure of the ventilation tube 1123 and the atomization seat 114 will be described. Figure 5 Shows Figure 4 The enlarged schematic diagram of the A part in the middle. Figure 5 As shown, in some embodiments, the gas flow channel of the atomizer seat 114 mentioned above may include a gas exchange hole 1141, a microchannel 1143 and a connecting channel 1142. The gas exchange hole 1141 is aligned with the gas exchange tube 1123 of the isolation plate 1121. If there are multiple gas exchange holes 1141, the number and position of the gas exchange holes 1141 correspond to the number and position of the gas exchange tube 1123 of the isolation plate 1121.

[0042] The microchannel 1143 is at least partially formed in the circumferential side wall of the atomizer seat 114. The connecting channel 1142 is arranged to connect at least one ventilation hole 1141 to the microchannel 1143 via the side wall of at least one ventilation hole 1141. In this way, the ventilation channel 1125 is formed by the ventilation tube 1123 of the isolation plate 1121, the ventilation hole 1141 on the atomizer seat 114, the microchannel 1143 and the connecting channel 1142. When the atomized matrix of the first liquid storage tank 115 flows to the second liquid storage tank 116, the negative pressure generated by the first liquid storage tank 115 causes the external gas to pass through the microchannel 1143, the connecting channel 1142 and the ventilation hole 1141 and the ventilation tube 1123 of the isolation plate 1121 and finally enter the first liquid storage tank 115.

[0043] The ventilation tube 1123 is sealed and connected to the atomizer seat 114. To this end, in some embodiments, at least the portion of the ventilation tube 1123 adjacent to the atomizer seat 114 and / or the atomizer seat 114 are made of elastic materials such as silicone at least in the circumferential portion of the ventilation hole 1141. In some embodiments, the ventilation tube 1123 can also be made of elastic materials as a whole, or the end of the ventilation tube 1123 abutting the atomizer seat 114 is made of elastic materials such as silicone, and the present disclosure does not specifically limit this. In some alternative embodiments, the isolation component 111 can also be made of elastic materials as a whole. In some further alternative embodiments, a removably sealed silicone 113 is also configured between the isolation component 111 and the atomizer seat 114, and the circumferential wall of the sealing silicone 113 abuts against the side wall of the second liquid storage bin 116, for providing a sealed connection between the ventilation tube 1123 of the isolation component 111 and the ventilation hole 1141 of the atomizer seat 114. In some embodiments, a smoke channel outlet 1145 is further provided at the center of the atomizer seat 114 , which is connected to the entrance of the smoke channel 131 of the suction nozzle 130 .

[0044] In some embodiments, the ventilation tube 1123 may have a circular cross-sectional shape. The ventilation tube 1123 having a circular cross-sectional shape is conducive to forming a liquid film, thereby effectively preventing the atomized substrate from flowing to the outside through the ventilation tube 1123. In some embodiments, the cross-sectional area of ​​the ventilation tube 1123 is the same along the direction from the first liquid storage tank 115 to the second liquid storage tank 116.

[0045] The above mainly describes an exemplary embodiment of a solution in which the ventilation channel 1125 connects the first liquid storage tank 115 to the external atmosphere via the atomizer seat 114. It should be understood that the above embodiment is only illustrative and is not intended to limit the scope of protection of the present disclosure. As long as the first liquid storage tank 115 can be connected to the external atmosphere, the ventilation channel 1125 can also be implemented by other appropriate structures.

[0046] For example, for the solution that the ventilation channel 1125 connects the first liquid storage tank 115 and the external atmosphere via the atomizer seat 114, in some alternative embodiments, the gas flow channel of the atomizer seat 114 may also include an extension tube extending toward the first liquid storage tank 115 and extending to the isolation plate 1121, and the structure of the extension tube may be similar to the structure of the ventilation tube 1123 mentioned above, except that it is a part of the atomizer seat 114 in this embodiment. In such an embodiment, a vent hole is provided at a position aligned with the extension tube on the isolation plate 1121, and the vent hole and the gas flow channel of the atomizer seat 114 including the extension tube together form the gas flow channel 1125.

[0047] In such an embodiment, in order to achieve sealing, at least the portion of the extension tube adjacent to the isolation plate 1121, and / or the isolation plate 1121 at least in the circumferential portion of the vent hole is made of an elastic material such as silicone to achieve airtight connection between the extension tube and the vent hole.

[0048] The above mainly describes a plurality of embodiments in which the ventilation channel 1125 connects the first liquid storage tank 115 with the external atmosphere via the atomizer seat 114. Of course, it should be understood that, as long as the first liquid storage tank 115 can be connected with the external atmosphere, the arrangement of the ventilation channel 1125 is not limited thereto. The ventilation channel 1125 can be arranged in any other appropriate manner.

[0049] For example, in some alternative embodiments, the ventilation channel 1125 may also be arranged on the wall of the first liquid storage tank 115. For example, the ventilation channel 1125 may have ventilation holes on the wall, and a one-way valve may be arranged in the ventilation holes to allow outside air to enter, while blocking the atomized substrate in the first liquid storage tank 115 from flowing out, thereby achieving ventilation while preventing leakage of the atomized substrate. In some embodiments, the wall of the first liquid storage tank 115 where the ventilation channel 1125 is arranged may include a wall of the first liquid storage tank 115 adjacent to the smoke channel 131.

[0050] The concept of the present disclosure will be described below mainly by taking a portion of the ventilation channel 1125 as an example, in which the ventilation tube 1123 extending from the isolation component 111 to the atomizer seat 114 is shown in the figure. It should be understood that other situations are similar and will not be described separately below.

[0051] In some embodiments, the isolation component 111 may further include at least one liquid tube 1122. The liquid tube 1122 may extend from the isolation plate 1121 in a direction from the first liquid storage tank 115 to the second liquid storage tank 116. The internal channel defined by the liquid tube 1122 is the liquid channel 1124 mentioned above. Figure 6, an embodiment in which the number of liquid tubes 1122 and corresponding liquid channels 1124 is two is shown. It is understandable that the number of at least one liquid tube 1122 and the number of corresponding at least one liquid channel 1124 may also be other numbers, for example, 1, 2 or 3 liquid tubes 1122 and corresponding liquid channels 1124 may be included, and the present disclosure does not specifically limit this.

[0052] The liquid channel 1124 may also take other forms besides the liquid tube 1122. For example, in some embodiments, the liquid channel 1124 may also be only a liquid hole formed in the isolation plate 1121, that is, there is no liquid tube 1122 extending downward from the isolation plate 1121. In the above embodiment, by providing a liquid tube extending in the direction from the first liquid storage tank 115 to the second liquid storage tank 116, it is possible to block the atomization matrix in the second liquid storage tank from flowing to the first liquid storage tank when the atomization device is tilted to a certain extent, thereby further reducing the possibility of dry burning of the atomization core. The concept of the present disclosure will be mainly described below by taking the example of the liquid channel 1124 being defined by the liquid tube 1122. It should be understood that the same is true for other situations, and they will not be described separately below.

[0053] In the embodiment of the present disclosure, the cross-sectional area of ​​each liquid channel 1124 is 1 mm 2 ~9mm 2 In this way, when the remaining amount of atomized matrix in the first liquid storage tank 115 and the second liquid storage tank 116 is small, the opening of the liquid channel 1124 may not be immersed in the atomized matrix. However, due to the small cross-sectional area of ​​the liquid channel 1124, under the action of the surface tension of the liquid, a liquid film will be formed at the opening of the liquid channel 1124, and the liquid film can further hinder the gas in the first liquid storage tank 115 from entering the second liquid storage tank 116, thereby further reducing the possibility that the atomized matrix in the second liquid storage tank 116 does not contact the atomization core. For example, the cross-sectional area of ​​each liquid channel 1124 in the liquid tube 1122 close to the first liquid storage tank 115 can be 2mm 2 , 3mm 2 , 4mm 2 , 5mm 2 , 6mm 2 , 7mm 2 , 8mm 2 or 9mm 2 In some embodiments, in order to facilitate the flow of the atomized substrate from the first liquid storage tank 115 to the second liquid storage tank 116 , the cross-sectional area of ​​each liquid channel 1124 may be gradually reduced in the direction from the first liquid storage tank 115 to the second liquid storage tank 116 .

[0054] During the use of the atomizing device 110, the ventilated gas enters the first liquid storage tank 115 from the outside through the venting channel 1125, and bubbles are generated in the atomized matrix of the first liquid storage tank 115. When the atomized matrix of the first liquid storage tank 115 flows to the second liquid storage tank 116 through the liquid channel 1124, due to the surface tension of the bubbles, the bubbles will not flow to the second liquid storage tank 116 through the liquid channel 1124. Therefore, in the case where the amount of the atomized matrix is ​​greater than the volume of the second liquid storage tank 116, the gas entering the first liquid storage tank 115 due to the venting is not easy to enter the second liquid storage tank 116, so that at least in this case, the second liquid storage tank 116 is always kept full of oil, so that the problem of insufficient contact between the atomizing core and the atomizing matrix mentioned above can be effectively avoided in most of the time period.

[0055] Figure 6 Although the embodiment in which the isolation component 111 includes a ventilation tube 1123 and a liquid tube 1122 extending from the isolation plate 1121 in the direction from the first liquid storage tank 115 to the second liquid storage tank 116 is shown, it should be understood that this is only illustrative and is not intended to limit the scope of protection of the present disclosure. In some alternative embodiments, the isolation component 111 may also include the ventilation tube 1123 or the liquid tube 1122 or not include the ventilation tube 1123 and the liquid tube 1122.

[0056] For example, in some alternative embodiments, the isolation component 111 may also only include a liquid hole for connecting the first liquid storage tank 115 and the second liquid storage tank 116 (as mentioned above), but does not include the ventilation pipe 1123 and the liquid pipe 1122. In such an embodiment, as mentioned above, the ventilation channel 1125 can be arranged on the tank wall of the first liquid storage tank 115.

[0057] In some alternative embodiments, in addition to the liquid hole, the isolation component 111 may also include the vent mentioned above. In such an embodiment, as mentioned above, the vent and the gas flow channel of the atomizer seat 114 jointly define the ventilation channel 1125, that is, the gas flow channel of the atomizer seat 114 may include an extension tube extending toward the first liquid storage tank 115 and extending to the isolation plate 1121 and aligned with the vent.

[0058] In some alternative embodiments, the isolation component 111 may also include a ventilation tube 1123 or a liquid tube 1122 extending from the isolation plate 1121 in a direction from the first liquid storage tank 115 to the second liquid storage tank 116 .

[0059] Figure 7 FIG. 1 is a schematic diagram showing the structure of the atomizer seat 114 according to an embodiment of the present disclosure. Figure 7As shown, in some embodiments, in addition to the gas circulation channel mentioned above, the atomizer seat 114 also includes a circulation channel 1144 that connects the atomizer core and the second liquid storage tank 116 fluid. In order to facilitate the flow of the atomized matrix, the inlet of the circulation channel 1144 can be at least partially aligned with at least one liquid channel 1124 in the axial direction B. The atomized matrix of the first liquid storage tank 115 flows to the second liquid storage tank 116 through the liquid channel 1124, and the atomized matrix contacts the atomizer core through the circulation channel 1144. One end of the liquid tube 1122 located in the second liquid storage tank 116 does not need to abut against the top of the atomizer seat 114, and it is only necessary that the channel of the liquid tube 1122 is at least partially arranged relative to the circulation channel 1144 to allow the atomized matrix to flow in.

[0060] It can be seen from the above description that when the atomizer device 110 of the embodiment of the present disclosure is inverted for suction (which can also be understood as suction at a negative angle) or flat for suction or suction at any other appropriate angle, the gas entering the first liquid storage tank 115 due to ventilation is not easy to enter the second liquid storage tank 116, so that during most of the time period, the atomization matrix in the second liquid storage tank 116 can always remain in a full oil state, so the atomization core can maintain sufficient contact with the atomization matrix in the second liquid storage tank 116, avoiding the phenomenon of dry burning of the atomization core, thereby further improving the user experience.

[0061] The above descriptions of various implementations of the present disclosure are exemplary, non-exhaustive, and not limited to the disclosed implementations. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described implementations. The selection of terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the various implementations disclosed herein.
