An air inlet channel and a liquid inlet channel are separated by a gas-liquid separation member. When the atomization liquid enters the gas channel, the liquid level of the atomization liquid rises.

When the air inlet blocking member is wetted, the atomization liquid after the liquid level drops will form an oil film at the position of the air inlet hole; a sealed space is formed at the end of the gas channel. Due to the increase in air pressure in this sealed space, the liquid level of the atomization liquid located in the gas channel is driven to drop, that is, the air inlet hole is located in the sealed space, and it is difficult for the atomization liquid to pass through the air inlet hole. A good atomization effect is maintained.

Description

Technical Field

[0001] This application relates to the field of atomizers, and in particular, to an atomization core, an atomization core assembly, and an atomizer. Background Art

[0002] The electronic heating atomization technology is a technology that uses electric heating to atomize a liquid, so that the atomized liquid reaches the boiling point to generate steam, and the steam forms a special aerosol after mixing with air. Therefore, the design of the atomizer needs to consider many factors. For example, during the use of the atomizer, it is necessary to achieve the effect of no liquid leakage, or to maintain the atomization core from getting burnt during the use of the atomizer. Because, referring to Figure 1 , during the use of the atomizer, a liquid storage chamber is provided in the atomizer. The liquid storage chamber is generally used to store the atomized liquid. When the atomized liquid is consumed, the air pressure and hydraulic pressure in the liquid storage chamber change at any time. In addition, in the related art, most of the liquid guiding members used inside the atomizer not only serve as a medium for conducting the atomized liquid, but also serve as a medium for external air to enter the liquid storage chamber. Therefore, it will cause the unstable conduction of the atomized liquid by the liquid guiding material, resulting in a poor atomization effect.

[0003] In view of the above related art, the inventor found that the liquid guiding member in the atomization core of the related art is difficult to maintain the stable conduction of the atomized liquid, resulting in a poor atomization effect. Summary of the Invention

[0004] In order to maintain the atomization effect of the atomization core, this application provides an atomization core, an atomization core assembly, and an atomizer.

[0005] The atomization core, the atomization core assembly, and the atomizer provided by this application adopt the following technical solutions:

[0006] An atomization core includes a support member, a heating member, and a mounting member. The support member is provided with an accommodation cavity. The heating member is connected to the mounting member, and both the heating member and the mounting member are disposed in the accommodation cavity. An air inlet hole and a liquid inlet hole are provided on the side wall of the support member, and an air inlet is provided at the top of the support member. The air inlet is used for allowing external air to enter and enter the liquid storage chamber through the air inlet hole, and the liquid inlet hole is used for allowing the atomized liquid in the liquid storage chamber to enter the accommodation cavity.

[0007] By adopting the above technical solution, the air inlet hole is used to introduce external gas into the liquid storage chamber, and the liquid inlet hole is used to introduce the atomized liquid in the liquid storage chamber into the accommodation cavity. During the process of the atomized liquid entering the accommodation cavity, there is no interference from external gas, so that the penetration effect of the atomized liquid can be maintained, and further the atomization effect of the good atomization core can be maintained.

[0008] Optionally, a plurality of groups of the air inlet holes and the liquid inlet holes are provided, and the plurality of groups of air inlet holes and the liquid inlet holes are evenly distributed circumferentially along the axis of the support member, and the air inlet holes are located above the liquid inlet holes.

[0009] By adopting the above technical solution, multiple groups of air inlet holes and liquid inlet holes are used to improve the atomization efficiency of the atomization core. When the liquid level of the atomizing liquid in the liquid storage chamber is between the air inlet hole and the liquid inlet hole, due to the hydraulic pressure of the atomizing liquid outside the liquid inlet hole, external gas will not pass through the liquid inlet hole and will not affect the penetration of the atomizing liquid.

[0010] Optionally, the vertical projections of the air inlet hole and the liquid inlet hole do not overlap.

[0011] By adopting the above technical solution, external gas will not affect the introduction path of the atomizing liquid when entering the liquid storage chamber through the air inlet hole. When the air inlet hole is directly above the liquid inlet hole, it may occur that the gas enters the atomizing liquid and interferes with the flow path of the atomizing liquid, reducing the atomizing liquid entering the liquid inlet hole, resulting in a change in the penetration of the atomizing liquid and affecting the atomization effect of the overall atomization core.

[0012] Optionally, it further includes an air inlet shielding member and a liquid guiding member. The air inlet shielding member is arranged on one side of the air inlet hole, and the air inlet shielding member is used to absorb the atomizing liquid entering the air inlet hole; the liquid guiding member is arranged on one side of the liquid inlet hole, and the liquid guiding member is used to guide the atomizing liquid entering the liquid inlet hole to the heating member.

[0013] By adopting the above technical solution, the air inlet shielding member is located on the path where the gas passes through the air inlet hole. When the air inlet shielding member adopts an oil-absorbing and breathable material, such as a liquid guiding cotton or a porous material such as porous ceramics, or a dense material with small holes. When the atomizing liquid of the atomizer enters through the air inlet hole, it will first be absorbed by the air inlet shielding member. When the air inlet shielding member is wetted, the atomizing liquid will form an oil film at the air inlet hole, and at this time, the atomizing liquid outside the air inlet hole is in a sealed environment inside the liquid storage member, thus forming a sealed liquid storage member. As the atomizing liquid inside the liquid storage member is consumed, a chamber with a relatively large pressure will be formed inside the liquid storage member. This chamber forms a negative pressure and the negative pressure makes the liquid level of the atomizing liquid below the air inlet hole. Therefore, the atomizing liquid no longer leaks to the air inlet hole. And when the oil film is broken by external gas, the external gas will preferentially enter the atomizing liquid and enter the liquid inlet hole along with the atomizing liquid, rather than directly entering the liquid inlet hole. Thus, a good atomization effect is maintained; and it is not affected by the usage amount of the atomizing liquid in the liquid storage chamber.

[0014] An atomization core assembly includes a gas-liquid separation member. The gas-liquid separation member is provided with a through cavity, and the atomization core is disposed through the through cavity. The gas-liquid separation member is used to form a stable gas channel for the path of external gas entering the liquid storage chamber, and the gas-liquid separation member is also used to form a stable liquid channel for the path of the atomizing liquid in the liquid storage chamber entering the atomization core.

[0015] By adopting the above technical solution, since the gas channel and the liquid channel are independent and stable, the inflow paths of the external gas and the atomized liquid are separated; and the liquid guiding member does not play the role of guiding the external gas, and the liquid guiding member is only used to conduct the atomized liquid, so as to maintain a good atomization effect.

[0016] Optionally, there is a spacing between the lower cavity wall of the through cavity and the lower outer wall of the support member, and the spacing forms a liquid inlet gap for the atomized liquid in the liquid storage chamber to enter the through cavity.

[0017] By adopting the above technical solution, when the atomized liquid enters the through cavity through the liquid inlet gap, the principle of a communicating vessel is formed, and when the liquid level of the atomized liquid is relatively high, it also needs to pass through the liquid inlet hole and the air inlet hole in sequence. Thus, the situation of the atomized liquid entering the air inlet hole is reduced.

[0018] Optionally, a partition portion is provided on the side wall of the through cavity, and the partition portion is used to separate the air inlet hole and the liquid inlet hole. The partition portion is vertically arranged and is disposed between the adjacent air inlet hole and the liquid inlet hole.

[0019] By adopting the above technical solution, the direction of the external gas entering the liquid inlet hole is successively to enter the accommodation cavity through the air inlet, then enter the liquid inlet gap from the air inlet hole in the accommodation cavity and then enter the atomized liquid, and then enter the liquid inlet hole from the atomized liquid. The whole path is long and not likely to occur. Therefore, the gas-liquid separation member can separate the air inlet channel and the liquid inlet channel, so as to maintain the stability of the atomized liquid passing through the liquid inlet hole, and further maintain the stability of the atomization effect.

[0020] Optionally, a blocking portion is further provided on the side wall of the through cavity. The blocking portion is connected to the partition portion, the blocking portion is located above the air inlet hole, and the side of the blocking portion away from the cavity wall of the through cavity presses against the support member, and the side of the partition portion away from the cavity wall of the through cavity presses against the support member.

[0021] By adopting the above technical solution, when the atomization liquid enters the gas channel, the liquid level of the atomization liquid rises. At the beginning, the atomization liquid will penetrate through the air inlet hole to the air inlet shielding member. When the air inlet shielding member is wetted, the atomization liquid after the liquid level drops will form an oil film at the position of the air inlet hole; a sealed space is formed at the end of the gas channel. Due to the increase in the air pressure in this sealed space, the liquid level of the atomization liquid located in the gas channel is driven to drop, that is, the air inlet hole is located in the sealed space, and it is difficult for the atomization liquid to pass through the air inlet hole. When the atomization liquid is gradually consumed, the liquid level of the atomization liquid in the gas channel drops, the air pressure in the sealed space becomes smaller, and the gas entering from the air inlet breaks through the oil film, enabling the internal and external air to communicate. At this time, the liquid level of the atomization liquid in the gas channel rises. When the liquid level of the atomization liquid continues to be above the air inlet hole, the oil film is generated, and the above process is repeated. When the liquid level of the atomization liquid is below the air inlet hole, the gas enters the gas channel from the outside through the air inlet hole. The overall process achieves dynamic balance. When the atomization liquid enters the liquid channel, the air pressure does not change, and the liquid level of the atomization liquid is only affected by consumption, thereby maintaining a good effect of the atomization liquid entering the atomization core; and then achieving the effect of gas-liquid separation.

[0022] An atomizer includes a housing assembly, an atomization core mounting seat, and a battery assembly. The housing assembly is provided with an installation cavity. The atomization core assembly is disposed in the installation cavity. The atomization core assembly is connected to the atomization core mounting seat, and the atomization core assembly is electrically connected to the battery assembly; the atomization core mounting seat is located below the atomization core assembly, and the edge of the atomization core mounting seat is attached to the cavity wall of the installation cavity.

[0023] By adopting the above technical solution, the spatial setting of the atomization core mounting seat enables the liquid storage chamber to be set as a sealed space, maintaining the stability of the atomization liquid in the liquid storage chamber permeating to the atomization core.

[0024] Optionally, the housing assembly sequentially includes a first housing member, a second housing member, and a third housing member in the vertical direction. The first housing member is connected to the second housing member, the second housing member is connected to the third housing member. An opening is provided at the top of the first housing member, and the opening communicates with the air inlet; an air supply port is provided at the bottom of the third housing member, and the air supply port is used for external air to enter the installation cavity.

[0025] By adopting the above technical solution, both the opening and the air supply port are used for external gas to enter the atomizer to maintain a good atomization effect.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When the atomizing liquid of the atomizer enters through the air inlet hole, it will first be absorbed by the air inlet blocking member. After the air inlet blocking member is wetted, the atomizing liquid will form an oil film at the air inlet hole. At this time, the atomizing liquid outside the air inlet hole is in a sealed environment inside the liquid storage member, thus forming a sealed liquid storage member. As the atomizing liquid inside the liquid storage member is consumed, a chamber with a relatively large pressure will be formed inside the liquid storage member. This chamber forms a negative pressure, and the negative pressure causes the liquid level of the atomizing liquid to be below the air inlet hole. Therefore, the atomizing liquid no longer leaks to the air inlet hole;

[0028] 2. The air inlet channel and the liquid inlet channel are independent of each other and are difficult to interfere with each other, maintaining a good atomization effect;

[0029] 3. When the atomizing liquid enters the gas channel, the liquid level of the atomizing liquid rises. At the beginning, the atomizing liquid will penetrate through the air inlet hole to the air inlet blocking member. After the air inlet blocking member is wetted, the atomizing liquid after the liquid level drops will form an oil film at the position of the air inlet hole; making the end of the gas channel form a sealed space. Due to the increase in air pressure in this sealed space, it drives the liquid level of the atomizing liquid located in the gas channel to drop, that is, the air inlet hole is located in the sealed space, and it is difficult for the atomizing liquid to pass through the air inlet hole.

Detailed implementation manners

[0042] The following Figure 2-11 further elaborates on the present application in detail.

[0043] The embodiment of the present application discloses an atomization core, an atomization core assembly and an atomizer. Among them, the atomization core is used to be placed in the atomizer.

[0044] Referring to Figure 2 and Figure 3 , an atomization core includes a support member 1, a heating member 2 and a mounting member 3. Specifically, the support member 1 is provided with an accommodation cavity 11, and both the heating member 2 and the mounting member 3 are arranged in the accommodation cavity 11. The support member 1 is hollow, and the top of the support member 1 is provided as an air inlet 12, and the air inlet 12 communicates with the outside. Moreover, the side wall of the support member 1 is provided with a liquid inlet hole 14 and an air inlet hole 13, wherein the air inlet hole 13 is located above the liquid inlet hole 14. The liquid inlet hole 14 is used for the atomization liquid in the atomizer to enter, and the air inlet hole 13 is used for the gas entering the accommodation cavity 11 from the air inlet 12 to pass through the air inlet hole 13.

[0045] Referring to Figure 3 and Figure 4 , multiple groups of liquid inlet holes 14 are provided, and the multiple groups of liquid inlet holes 14 are evenly distributed circumferentially along the axis of the support member 1. In this embodiment, four groups of liquid inlet holes 14 are provided. The air inlet holes 13 are arranged above the liquid inlet holes 14, and moreover, in this embodiment, four groups of air inlet holes 13 are also provided, and the four groups of air inlet holes 13 are evenly distributed circumferentially along the axis of the support member 1. In addition, in the vertical projection, the positions of the liquid inlet holes 14 and the air inlet holes 13 do not overlap, and the size of the air inlet holes 13 is smaller than the size of the liquid inlet holes 14.

[0046] Referring to Figure 3 and Figure 4, since the atomizing core is in the environment of the atomizing liquid, the atomizing liquid may enter the accommodating cavity 11 from the air inlet hole 13. In order to reduce the atomizing liquid of the atomizer from entering the atomizing core, in this embodiment, an air inlet shielding member 4 is provided. The air inlet shielding member 4 is arranged on the side wall of the support member 1, and moreover, the air inlet shielding member 4 is located on the path where the gas passes through the air inlet hole 13. In addition, the air inlet shielding member 4 is made of an oil-absorbing and breathable material, such as a liquid-conducting cotton or a porous material of porous ceramics, or a dense material with small holes. In this embodiment, it is preferably a liquid-conducting surface or a liquid storage cotton or a fiber woven tube. The purpose of such a setting is that when the atomizing liquid of the atomizer enters from the air inlet hole 13, it will first be absorbed by the air inlet shielding member 4. When the air inlet shielding member 4 is wetted, the atomizing liquid will form an oil film at the air inlet hole 13. At this time, the atomizing liquid outside the air inlet hole 13 is in a sealed environment inside the liquid storage member, thus forming a sealed liquid storage member. As the atomizing liquid inside the liquid storage member is consumed, a chamber with a relatively large pressure will be formed inside the liquid storage member. This chamber forms a negative pressure, and the negative pressure makes the liquid level of the atomizing liquid located below the air inlet hole 13. Therefore, the liquid does not leak to the air inlet hole 13.

[0047] Referring to Figure 4 , it further includes a liquid guiding member 5. The liquid guiding member 5 is used to guide the atomizing liquid entering the accommodating cavity from the liquid inlet hole 14 to the heating member 2. Specifically, the liquid guiding member 5 is arranged inside the accommodating cavity 11, and the liquid guiding member 5 is located on one side of the liquid inlet hole 14. In this embodiment, the liquid guiding member 5 is made of multiple layers of liquid-conducting cotton sheets or porous ceramics or a combination of both. In this embodiment, it is preferably multiple layers of liquid-conducting cotton sheets. Moreover, the porosity of the liquid guiding member 5 is between 30% and 80%, and its micropore gaps are generally distributed between 1 and 100 μm. In addition, in this embodiment, the thickness of the air inlet shielding member 4 is within 2 / 3 of the thickness of the liquid guiding member 5.

[0048] The purpose of such a setting is that since the thickness of the shielding object at the position of the air inlet hole 13 is less than the thickness of the shielding object at the position of the liquid inlet hole 14, when the external atomizing liquid is consumed, the negative pressure of the external atomizing liquid decreases. The gas entering from the air inlet 12 will preferentially break through the oil film at the air inlet hole 13 so that the gas enters the position where the external atomizing liquid is stored, rather than entering from the position of the liquid inlet hole 14 with a relatively thick position. In addition, the horizontal height of the liquid inlet hole 14 is located below the air inlet hole 13, and the area of the liquid inlet hole 14 is also larger than the area of the air inlet hole 13. Therefore, the oil film pressure at the liquid inlet hole 14 is greater than the oil film pressure at the air inlet hole 13, and the gas can only enter the position where the atomizing liquid is stored from the air inlet hole 13. Therefore, only the atomizing liquid can pass through the liquid inlet hole 14, so the liquid inlet hole 14 is only used as an inlet channel, thus separating the inflow path of the external gas and the inflow path of the atomizing liquid. The liquid guiding member 5 does not play the role of guiding the external gas. The liquid guiding member 5 is only used to conduct the atomizing liquid, so as to maintain a good atomizing effect; and it is not affected by the usage amount of the atomizing liquid in the liquid storage bin 100.

[0049] The implementation principle of the atomization core in the embodiment of the present application is as follows: The horizontal height of the liquid inlet hole 14 is below the air inlet hole 13, and the area of the liquid inlet hole 14 is also larger than that of the air inlet hole 13. Therefore, the oil film pressure at the liquid inlet hole 14 is greater than the oil film pressure at the air inlet hole 13, and gas can only enter the position where the atomization liquid is stored from the air inlet hole 13. The liquid guiding member 5 does not play the role of guiding external gas. The liquid guiding member 5 is only used to conduct the atomization liquid, so as to maintain a good atomization effect; and it is not affected by the usage amount of the atomization liquid in the liquid storage chamber 100. Therefore, only the atomization liquid can pass through the liquid inlet hole 14, so the liquid inlet hole 14 is only used as a liquid inlet channel, thereby separating the inflow path of external gas and the inflow path of the atomization liquid.

[0050] Embodiment Two:

[0051] Refer to Figure 5 and Figure 6 A kind of atomization core assembly includes the above atomization core, and also includes a gas-liquid separation member 6.

[0052] Refer to Figure 7 and Figure 8 wherein, the atomization core is inserted through the gas-liquid separation member 6, and the gas-liquid separation member 6 is used to form stable gas channels 7 and liquid channels 8 for the gas entry path and the liquid entry path.

[0053] Refer to Figure 7 and Figure 9 The gas-liquid separation member 6 is provided with a through cavity 61, and the atomization core is inserted through the through cavity 61. Moreover, a partition portion 62 is provided on the side wall of the through cavity 61, and the partition portion 62 is used to separate the air inlet hole 13 and the liquid inlet hole 14. Specifically, in this embodiment, the partition portion 62 includes a first partition unit 621 and a second partition unit 622, and a liquid inlet gap 63 is formed between the first partition unit 621, the second partition unit 622, the outer wall of the atomization core and the wall of the through cavity 61. The atomization liquid can enter the liquid channel 8 from the liquid inlet gap 63, and then the atomization liquid flows into the liquid guiding member 5 from the liquid inlet hole 14, and the liquid guiding member 5 guides the atomization liquid to the heating member 2 for heating atomization.

[0054] Refer to Figure 6 The number of the partition portions 62 is set according to the number of the liquid inlet holes 14. In this embodiment, four groups of partition portions 62 are provided. The four groups of liquid inlet holes 14 are respectively located within the vertical projection ranges of the four groups of different partition portions 62.

[0055] Refer to Figure 8 and Figure 10, a barrier portion 64 is further provided on the side wall of the through cavity 61. The barrier portion 64 is connected to the first partition unit 621 of a group of partition portions 62 and the second partition unit 622 of another group of partition portions 62, and the barrier portion 64 is located above the air inlet hole 13. Therefore, when the atomized liquid enters the gas passage 7, the liquid level of the atomized liquid rises. At the beginning, the atomized liquid will penetrate through the air inlet hole 13 to the air inlet shielding member 4. When the air inlet shielding member 4 is wetted, the atomized liquid after the liquid level drops will form an oil film at the position of the air inlet hole 13; a sealed space is formed at the end of the gas passage 7. Due to the increase in the air pressure in this sealed space, the liquid level of the atomized liquid located in the gas passage 7 is driven to drop, that is, the air inlet hole 13 is located in the sealed space, and it is difficult for the atomized liquid to pass through the air inlet hole 13. When the atomized liquid is gradually consumed, the liquid level of the atomized liquid in the gas passage 7 drops, the air pressure in the sealed space becomes smaller, and the gas entering from the air inlet 12 breaks through the oil film, enabling the internal and external air to communicate, and the external gas enters the liquid storage chamber 100. At this time, the liquid level of the atomized liquid in the gas passage 7 rises. When the liquid level of the atomized liquid continues to be above the air inlet hole 13, the oil film is generated, and the above process is repeated. When the liquid level of the atomized liquid is below the air inlet hole 13, the gas passes through the air inlet hole 13 from the outside and enters the gas passage 7. The overall process achieves dynamic balance, and the external gas will not interfere with the atomized liquid entering the atomization core, maintaining a stable atomization effect.

[0056] Refer to Figure 6 and Figure 9 , since there is no barrier portion 64 to block the upper and lower sides of the first partition unit 621 and the second partition unit 622 in the same group of partition portions 62, therefore, when the atomized liquid enters the liquid passage 8, the air pressure will not change, and the liquid level of the atomized liquid is only affected by consumption, thereby maintaining a good effect of the atomized liquid entering the atomization core.

[0057] The implementation principle of an atomization core component in an embodiment of this application: When the atomization liquid enters the gas passage 7, the liquid level of the atomization liquid rises. At the beginning, the atomization liquid will penetrate through the air inlet hole 13 to the air inlet shielding member 4. When the air inlet shielding member 4 is wetted, the atomization liquid after the liquid level drops will form an oil film at the position of the air inlet hole 13; a sealed space is formed at the end of the gas passage 7. Due to the increase in air pressure in this sealed space, the liquid level of the atomization liquid located in the gas passage 7 is driven to drop, that is, the air inlet hole 13 is located in the sealed space, and it is difficult for the atomization liquid to pass through the air inlet hole 13. When the atomization liquid is gradually consumed, the liquid level of the atomization liquid in the gas passage 7 drops, the air pressure in the sealed space becomes smaller, and the gas entering from the air inlet 12 breaks through the oil film, enabling the internal and external air to communicate. At this time, the liquid level of the atomization liquid in the gas passage 7 rises. When the liquid level of the atomization liquid continues to be above the air inlet hole 13, an oil film is generated, and the above process is repeated. When the liquid level of the atomization liquid is below the air inlet hole 13, gas enters the gas passage 7 from the outside through the air inlet hole 13. The overall process achieves dynamic balance. When the atomization liquid enters the liquid passage 8, the air pressure does not change, and the liquid level of the atomization liquid is only affected by consumption, thereby maintaining a good effect of the atomization liquid entering the atomization core; and then achieving the effect of gas-liquid separation.

[0058] Embodiment Three:

[0059] Refer to Figure 11 , an atomizer, including a housing assembly 9, the above-mentioned atomization core component, an atomization core mounting seat 10, and a battery assembly 011. Among them, the housing assembly 9 is provided with an installation cavity 91, and the atomization core component, the atomization core mounting seat 10, the battery assembly 011, and the control component are all placed in the installation cavity 91.

[0060] Refer to Figure 11 , the housing assembly 9 sequentially includes a first housing member 92, a second housing member 93, and a third housing member 94 from top to bottom in the vertical direction. The installation cavity 91 is opened in the second housing member 93. Moreover, the atomization core mounting seat 10 is arranged in the installation cavity 91, and the atomization core mounting seat 10 is detachably connected to the side wall of the installation cavity 91, so that the installation cavity 91 is divided into a first chamber 911 and a second chamber 912. The first chamber 911 is used for storing atomization liquid, and the second chamber 912 is used for storing the battery assembly 011 and the control component.

[0061] Refer to Figure 11 , the atomization core component penetrates through the first chamber 911, and the atomization core component is connected to the first housing member 92. One end of the first housing member 92 away from the second housing member 93 is provided with an opening, and the opening communicates with the air inlet 12. External gas can enter the air inlet 12 from the opening. The atomized gas after the internal atomization liquid is atomized can also flow out from the opening through the air inlet 12.

[0062] Refer to Figure 11, the outer wall of the atomization core assembly, the bottom wall of the first housing member 92, the upper surface of the atomization core mounting seat 10, and the inner wall of the first chamber 911 form a liquid storage chamber 100 for storing atomization liquid. Therefore, the liquid storage chamber 100 is in a sealed state, and the atomization liquid in the liquid storage chamber 100 is affected by the negative pressure of the sealed chamber.

[0063] Referring to Figure 11 , in order to maintain a good liquid inlet effect, in this embodiment, there is a gap between the bottom wall of the atomization core assembly and the upper surface of the atomization core mounting seat 10.

[0064] Referring to Figure 11 , since the atomizer needs external gas to enter the atomizer during the atomization process, a gas supply port 941 is provided at the bottom of the third housing member 94, and the gas supply port 941 is used to connect the second chamber 912 with the outside.

[0065] Referring to Figure 11 , the battery assembly 011 includes a battery member and a switch member. Among them, the battery member is electrically connected to the switch member. In this embodiment, the switch member adopts an induction switch, and moreover, the switch member is arranged on one side of the gas supply port 941. When there is air flow at the gas supply port 941, the induction switch is activated, and the atomizer performs the atomization function.

[0066] The implementation principle of an atomizer in an embodiment of the present application: The atomization core assembly is fixed at the upper and lower ends, and moreover, the outer periphery of the atomization core assembly is sealed, thereby forming a sealed liquid storage chamber 100. In addition, there is a gap for the atomization liquid to enter the atomization core between the lower part of the gas-liquid separation member 6 and the atomization core mounting seat 10. When starting to use, the atomization liquid enters the liquid channel 8 and the gas channel 7 through the gap. The atomization liquid is first introduced to the heating member 2 through the liquid inlet hole 14 by the liquid guiding member 5 for atomization. When the usage amount of the atomization liquid is small, a small amount of atomization liquid will be absorbed by the air intake shielding member 4 through the air permeable hole, and then the atomization liquid will form an oil film at the air intake hole 13; at this time, a sealed space is formed in the air intake channel, and the negative pressure generated in the sealed space makes the liquid level of the atomization liquid in the sealed space located below the air intake hole 13. As the atomization liquid is consumed, the negative pressure in the sealed space decreases, and external gas passes through the air intake hole 13, causing the oil film at the air intake hole 13 to break. The external gas enters the liquid storage chamber 100 through the gas channel 7 and then enters the liquid channel 8, and the air intake channel and the liquid channel 8 are separated and do not interfere with each other. Therefore, it can be ensured that the liquid inlet rate of the atomization core will not change due to the amount of liquid and air pressure in the liquid storage chamber 100.

[0067] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
