Abstract

Disclosed are an atomizer (1) and an electronic atomization device. A first intersection (1511) of the atomizer (1) and the electronic atomization device is located between a first air outlet (12) and an atomization assembly (14), and a second intersection (1512) is located between a first air inlet (11) and the atomization assembly (14). When the first air outlet (12) is subjected to a vaping action, an airflow flowing from the first air inlet (11) to the first air outlet (12) is generated in a first airflow channel (13), and the air pressure of the first airflow channel (13) at the second intersection (1512) is greater than the air pressure of a second airflow channel (151) at the second intersection (1512). Therefore, the pressure difference between the first airflow channel (13) and the second airflow channel (151) at the second intersection (1512) can drive an accumulated liquid in the first airflow channel (13) close to the second intersection (1512) to enter the second airflow channel (151) by means of the second intersection (1512) and be absorbed by a capillary liquid absorption structure (152), and the situation where the atomizer (1) and the electronic atomization device leak the liquid can be ameliorated.

Description

TECHNICAL FIELD

BACKGROUND

A conventional electronic atomizing device such as an e-cigarette is usually configured with an atomizer. The atomizer can atomize an aerosol substrate stored in the atomizer for a user to inhale.

On the one hand, the aerosol substrate leaking to the outside of the housing exerts a negative impact on the user experience, and on the other hand, the aerosol substrate is prone to permeate into a main unit (that is, a battery assembly) of the electronic atomizing device, thereby damaging a circuit, a component, and the like in the main unit, and even scrapping the main unit in a severe case.

DETAILED DESCRIPTION

In order to make the objects, technical solutions and advantages of this disclosure clearer, the technical solutions of embodiments of this disclosure will be clearly and comprehensively described in the following with reference to the embodiments of this disclosure. It is apparent that the described embodiments are a part of the embodiments of this disclosure, rather than all the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of this disclosure without creative efforts shall fall within the protection scope of this disclosure. The following embodiments and features in the embodiments may be mutually combined if no conflict occurs.
FIG. 1 is a schematic structural diagram a first embodiment of an atomizer according to this disclosure.
To resolve the technical problem of severe liquid leakage of the atomizer and the electronic atomizing device in the related art, an embodiment of this disclosure provides an atomizer 1. The atomizer 1 includes a first air inlet 11 and a first air outlet 12. The atomizer 1 further includes a first airflow channel 13, the first airflow channel 13 is in communication with the first air inlet and the first air outlet 12, and an atomizing assembly 14 is arranged in the first airflow channel 13. The atomizer 1 further includes a second airflow channel 151, where the two ends of the second airflow channel 151 intersect respectively with the first airflow channel 13 to form a first intersection 1511 and a second intersection 1512, the first intersection 1511 is located between the first air outlet 12 and the atomizing assembly 14, and the second intersection 1512 is located between the first air inlet 11 and the atomizing assembly 14. The atomizer 1 further includes a capillary liquid absorbing structure 152, and the capillary liquid absorbing structure 152 is connected to the second airflow channel 151. When an inhaling action occurs at the first air outlet 12, accumulated liquid in the first airflow channel 13 that is close to the second intersection 1512 enters the second airflow channel 151 through the second intersection 1512 and is absorbed by the capillary liquid absorbing structure 152. Detailed descriptions are provided below.
In an embodiment, the atomizer 1 is a component that is configured to atomize an aerosol substrate in an electronic atomizing device. The electronic atomizing device to which the atomizer 1 of this embodiment is applied may be an e-cigarette or the like, and the atomizer 1 is configured to atomize e-liquid (that is, an aerosol substrate) for a user to inhale. Certainly, in other embodiments of this disclosure, the electronic atomizing device to which the atomizer 1 of this embodiment is applied is not limited to a product form of the e-cigarette. For example, the atomizer 1 of the electronic atomizing device may be further configured to atomize liquid medicine, or the like. The atomized liquid medicine is provided for the user to inhale, so as to assist in the user's medicine treatment. The following description is given by using an example in which a product form of the electronic atomizing device to which the atomizer 1 of this embodiment is applied is the e-cigarette, which is only for description needs and is not intended to constitute a limitation.
Specifically, the atomizer 1 includes the first air inlet 11, the first air outlet 12, and the first airflow channel 13 that is in communication with the first air inlet 11 and the first air outlet 12. When the user inhales, that is, an inhaling action occurs at the first air outlet 12, external air enters the first airflow channel 13 from the first air inlet 11 and flows toward the first air outlet 12 along the first airflow channel 13.
Further, the atomizing assembly 14 is arranged in the first airflow channel 13. The atomizing assembly 14 is a component that is configured to atomize an aerosol substrate in the atomizer 1. When the user inhales, the air entering the first airflow channel 13 from the first air inlet 11 carries the aerosol substrate atomized by the atomizing assembly 14 and flows toward the first air outlet 12, and is outputted from the first air outlet 12 for the user to inhale.
Alternatively, the atomizing assembly 14 is preferably a porous heating body, which absorbs the aerosol substrate by a capillary force and generates heat to atomize the aerosol substrate. Preferably, the atomizing assembly 14 may be a porous ceramic heating body, or the like, and a heating film may be further arranged at the bottom of the atomizing assembly 14. Certainly, in other embodiments of this disclosure, the atomizing assembly 14 may alternatively be such designed that a fiber cotton and a heating wire are matched, which is not limited herein.
The atomizer 1 further includes the second airflow channel 151. The second airflow channel 151 is spaced apart from the first airflow channel 13, and the two ends of the second airflow channel 151 intersect respectively with the first airflow channel 13 to form the first intersection 1511 and the second intersection 1512.
The atomizer 1 further includes the capillary liquid absorbing structure 152, and the capillary liquid absorbing structure 152 is connected to the second airflow channel 151 and is configured to absorb the accumulated liquid entering the second airflow channel 151.
Because the atomizing assembly 14 is arranged in the first airflow channel 13, the aerosol substrate absorbed by the atomizing assembly 14 inevitably remains in the first airflow channel 13. In addition, because a temperature of the atomized aerosol substrate is relatively high, and a temperature of an inner wall of the first airflow channel 13 is relatively low, the atomized aerosol substrate undergoes a sharp temperature drop and condenses when contacting the inner wall of the first airflow channel 13, and the condensed aerosol substrate remains in the first airflow channel 13. Therefore, the foregoing factors cause the aerosol substrate to remain in the first airflow channel 13, that is, to form the accumulated liquid. However, when too much the accumulated liquid remains in the first airflow channel 13, the accumulated liquid inevitably leaks to the outside of the atomizer 1.
In view of this, in this embodiment, the second airflow channel 151 is designed. The first intersection 1511 is located between the first air outlet 12 and the atomizing assembly 14, and the second intersection 1512 is located between the first air inlet 11 and the atomizing assembly 14. That is, the first intersection 1511 is close to the first air outlet 12 relative to the second intersection 1512. In this way, when the inhaling action occurs at the first air outlet 12, the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, air pressure at the first intersection 1511 of the first airflow channel 13 is less than air pressure of the second airflow channel 151 at the first intersection 1511, and air pressure at the second intersection 1512 of the first airflow channel 13 is greater than air pressure of the second airflow channel 151 at the second intersection 1512. Therefore, a pressure difference between the first airflow channel 13 and the second airflow channel 151 at the second intersection 1512 drives accumulated liquid in the first airflow channel 13 that is close to the second intersection 1512 to enter the second airflow channel 151 through the second intersection 1512 and be absorbed by the capillary liquid absorbing structure 152 to reduce the accumulated liquid in the first airflow channel 13. Therefore, the liquid leakage of the atomizer 1 is reduced and the user experience is improved.
It should be noted that, when the inhaling action occurs at the first air outlet 12, the external air enters the first airflow channel 13 from the first air inlet 11. The air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13. In addition, part of the air entering the first airflow channel 13 from the first air inlet 11 flows into the second airflow channel 151 from the second intersection 1512, and the air in the second airflow channel 151 converges from the first intersection 1511 to the first airflow channel 13 to form a complete airflow path, as shown by dashed arrows in FIG. 1. That is, only when the inhaling action occurs at the first air outlet 12, the pressure difference is generated between the first airflow channel 13 and the second airflow channel 151 at the second intersection 1512. Therefore, the accumulated liquid in the first airflow channel 13 is driven to flow into the second airflow channel 151 through the second intersection 1512. When the inhaling action does not occur at the first air outlet 12, that is, when the user does not inhale, air pressure in the first airflow channel 13 is about one standard atmospheric pressure, namely, about 101.325 kPa, and an air pressure difference between the first airflow channel 13 and the second airflow channel 151 is not obvious. In this case, the second airflow channel 151 absorbs a relatively limited amount of the accumulated liquid in the first airflow channel 13.
In addition, in this embodiment, the second airflow channel 151 is configured to cooperate with the capillary liquid absorbing structure 152 to absorb the accumulated liquid in the first airflow channel 13, and is not a cavity used for storing the aerosol substrate of the atomizer 1. For example, in the electronic atomizing device in the product form of an e-cigarette, an e-liquid cavity is usually defined in the atomizer 1 to store e-liquid (that is, the aerosol substrate).
The first air inlet 11 and the first air outlet 12 of the atomizer 1 in this embodiment may be spaced apart along the straight-line direction, that is, the atomizer 1 in this embodiment is designed in a straight liquid form. Certainly, in other embodiments of this disclosure, the atomizer 1 may alternatively be designed in other forms than the straight liquid form, which is not limited herein.
In an embodiment, the second airflow channel 151 is connected to the capillary liquid absorbing structure 152, and is configured to absorb the accumulated liquid entering the second airflow channel 151 from the second intersection 1512.
Further, the capillary liquid absorbing structure 152 includes a plurality of capillary grooves 1521, and the capillary grooves 1521 can absorb and store the accumulated liquid entering the second airflow channel 151 from the second intersection 1512 by the capillary force, as shown in FIG. 1. In addition, the plurality of capillary grooves 1521 are spaced apart sequentially along the extension direction of the second airflow channel 151 and are in communication with the second airflow channel 151, capillary grooves 1521 that are relatively close to the second intersection 1512 are preferentially configured to absorb and store accumulated liquid entering the second airflow channel 151. A specific structural design and implementation of the capillary groove 1521 are described below.
Still referring to FIG 1, in an embodiment, the first airflow channel 13 includes an air outlet channel 131 and an atomizing cavity 132, the atomizing assembly 14 is arranged in the atomizing cavity 132. The air outlet channel 131 is in communication with the atomizing cavity 132 and the first air outlet 12, and the atomizing cavity 132 is in communication with the first air inlet 11. That is, the first air outlet 12, the air outlet channel 131, the atomizing cavity 132, and the first air inlet 11 are sequentially in communication with each other.
The cross-sectional area of the air outlet channel 131 is less than the cross-sectional area of the atomizing cavity 132. When the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, the cross-sectional area of the air outlet channel 131 is relatively small, a flow velocity of the air flow in the air outlet channel 131 is relatively high, and corresponding air pressure in the air outlet channel 131 is relatively low, which is conductive to increase a pressure difference between the air outlet channel 131 and the atomizing cavity 132, thereby making it convenient for the atomized aerosol substrate to be better provided for the user to inhale.
The cross-sections of both the air outlet channel 131 and the atomizing cavity 132 are perpendicular to their respective extension directions, an extension direction of the air outlet channel 131 is defined as a direction extending from the atomizing cavity 132 to the first air outlet 12, and an extension direction of the atomizing cavity 132 is defined as a direction extending from the first air inlet 11 to the air outlet channel 131. For example, in the atomizer 1 in the straight liquid form shown in FIG. 1, the extension directions of the air outlet channel 131 and the atomizing cavity 132 are both the direction from the first air inlet 11 to the first air outlet 12.
In addition, the first intersection 1511 is arranged in the air outlet channel 131, and the second intersection 1512 is arranged in the atomizing cavity 132. In this way, when the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, the air pressure in the air outlet channel 131 is less than the air pressure in the second airflow channel 151, and the air in the second airflow channel 151 flows into the air outlet channel 131 through the first intersection 1511. The air pressure in the atomizing cavity 132 is greater than the air pressure in the second airflow channel 151, and the air in the atomizing cavity 132 flows into the second airflow channel 151 through the second intersection 1512 to form the foregoing complete airflow path.
Certainly, in other embodiments of this disclosure, when the inhaling action occurs at the first air outlet 12, the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13. Therefore, in a direction from the first air inlet 11 to the first air outlet 12, the air pressure in the first airflow channel 13 gradually decrease. In view of this, the first intersection 1511 and the second intersection 1512 may alternatively be both arranged in the air outlet channel 131 or may be both arranged in the atomizing cavity 132. The first intersection 1511 is close to the first air outlet 12 relative to the second intersection 1512, a design for reducing the liquid leakage of the atomizer 1 in this embodiment of this disclosure may be implemented. In an exemplary embodiment, the second intersection 1512 is located at the bottom of the atomizing cavity 132, so that the accumulated liquid at the bottom of the atomizing cavity 132 may be absorbed by the capillary liquid absorbing structure 152 along the second airflow channel 151 during inhaling.
Specifically, when the air flow from the first air inlet 11 to the first air outlet 12 is generated in the first airflow channel 13, air pressure in the atomizing cavity 132 is P1, air pressure in the air outlet channel 131 is P2, and air pressure in the second airflow channel 151 is P3, P1 is greater than P3, and P3 is greater than P2.
The air pressure in the atomizing cavity 132 is greater than the air pressure in the second airflow channel 151. A pressure difference between the atomizing cavity 132 and the second airflow channel 151 at the second intersection 1512 drives the accumulated liquid in the atomizing cavity 132 that is close to the second intersection 1512 to enter the second airflow channel 151 through the second intersection 1512 and be absorbed by the capillary liquid absorbing structure 152.
In an embodiment, the accommodating space in the second airflow channel 151 and the capillary liquid absorbing structure 152 is less than the accommodating space in the atomizing cavity 132. The accommodating space is defined as space in a cavity to store the air and the aerosol substrate. A volume of the accommodating space in the second airflow channel 151 and the capillary liquid absorbing structure 152 is relatively small. When the air flow from the first air inlet 11 to the first air outlet is generated in the first airflow channel 13, a flow velocity of the air flow in the second airflow channel 151 and the capillary liquid absorbing structure 152 is relatively high, and the corresponding air pressure in the second airflow channel 151 and the capillary liquid absorbing structure 152 is relatively low, which is conductive to increase the pressure difference between the second airflow channel 151 and the atomizing cavity 132, that is, a force driving the accumulated liquid in the atomizing cavity 132 to enter the second airflow channel 151 is increased, such that the accumulated liquid in the first airflow channel 13 and especially in the accumulated liquid at the bottom of the atomizing cavity 132 is reduced, thereby alleviating the liquid leakage of the atomizer 1 and improving the user experience.
In addition, the second airflow channel 151 is spaced apart from the first airflow channel 13. Specifically, the second airflow channel 151 is spaced apart from the air outlet channel 131 and the atomizing cavity 132, and the second airflow channel 151 is in communication with the air outlet channel 131 and the atomizing cavity 132 through the first intersection 1511 and the second intersection 1512. Spacing apart is helpful to ensure the pressure difference between the second airflow channel 151 and each of the air outlet channel 131 and the atomizing cavity 132, so as to ensure that there is a sufficient pressure difference to drive the accumulated liquid in the atomizing cavity 132 to enter the second airflow channel 151, and to form the foregoing complete airflow path.
Optionally, a partition 16 may be arranged between the second airflow channel 151 and the first airflow channel 13, as shown in FIG. 1, so that the second airflow channel 151 is spaced apart from the first airflow channel 13, which is not limited herein.
It should be noted that, the atomizer 1 may further include a leak-proof cavity 15, the second airflow channel 151 and the capillary liquid absorbing structure 152 are arranged in the leak-proof cavity 15, the leak-proof cavity 15 is spaced apart from the first airflow channel 13, and the leak-proof cavity 15 intersects with and is in communication with the first airflow channel 13 through the first intersection 1511 and the second intersection 1512 respectively.
Certainly, in other embodiments of this disclosure, the second airflow channel 151 and the capillary liquid absorbing structure 152 may alternatively be designed as being integrally formed in the atomizer 1 described below instead of additionally designing the leak-proof cavity 15 in the atomizer 1 and then arranging the second airflow channel 151 and the capillary liquid absorbing structure 152 in the leak-proof cavity 15 described above.
In summary, the two ends of the second airflow channel of the atomizer provided in this disclosure intersect respectively with the first airflow channel to form a first intersection and a second intersection, the first intersection is located between the first air outlet and the atomizing assembly, and the second intersection is located between the first air inlet and the atomizing assembly. That is, the first intersection is close to the first air outlet relative to the second intersection. In this way, when an inhaling action occurs at the first air outlet, an air flow from the first air inlet to the first air outlet is generated in the first airflow channel, air pressure at the first intersection of the first airflow channel is less than air pressure of the second airflow channel at the first intersection, and air pressure at the second intersection of the first airflow channel is greater than air pressure of the second airflow channel at the second intersection. Therefore, a pressure difference between the first airflow channel and the second airflow channel at the second intersection drives accumulated liquid in the first airflow channel that is close to the second intersection to enter the second airflow channel through the second intersection and be absorbed by the capillary liquid absorbing structure to reduce the accumulated liquid in the first airflow channel especially at the bottom of the atomizing cavity. Therefore, the liquid leakage of the atomizer and the electronic atomizing device is reduced, thereby improving the user experience and reducing the risk of damage to a main unit of the electronic atomizing device caused by of an aerosol substrate permeating into the main unit.

In addition, a first communication groove 185 is provided on the portion of the separating member 184 facing the first intersection 1511, so that the first airflow channel 13 intersects with the second airflow channel 151 to form the first intersection 1511. A second communication groove 186 is provided on the portion of the separating member 184 facing the second intersection 1512, so that the first airflow channel 13 intersects with the second airflow channel 151 to form the second intersection 1512. The second communication groove 186 may also be a groove body similar to a capillary groove, which also absorbs the accumulated liquid in the first airflow channel 13 by the capillary force.
FIG. 4 shows a situation in which the atomizing cavity 132 and part of the air outlet channel 131 of the first airflow channel 13 are defined in the leak-proof component 18.

In addition, FIG. 4 further shows a situation in which the second airflow channel 151 and the capillary liquid absorbing structure 152 are arranged on two opposite sides of the first airflow channel 13 in the leak-proof component 18. Further, the second airflow channels 151 and the capillary liquid absorbing structures 152 on the two opposite sides of the first airflow channel 13 in the leak-proof component 18 are preferably arranged in mirror symmetry. Further, two sides of the leak-proof component 18 in a predetermined direction are respectively provided with a first intersection 1511 and a second intersection 1512. In addition, the two sides of the leak-proof component 18 in the predetermined direction are respectively provided with a first communication groove 185 and a second communication groove 186 that are respectively provided facing the first intersection 1511 and the second intersection 1512.

The predetermined direction (as shown by an arrow X in FIG. 4) is perpendicular to a direction (as shown by an arrow Y in FIG. 4) along the second airflow channels 151 on the two sides of the first airflow channel 13 in the leak-proof component 18, and is perpendicular to an extension direction (as shown by an arrow Z in FIG. 4) of the first airflow channel 13 in the leak-proof component 18.
Still referring to FIG 4, in an embodiment, the plurality of capillary grooves 1521 surrounding the outer periphery of the first airflow channel 13 are provided on the outer wall of the leak-proof component 18, and the capillary grooves 1521 can absorb and store the accumulated liquid entering the second airflow channel 151 from the second intersection 1512 by the capillary force.
Specifically, a plurality of fins 1522 surrounding the outer periphery of the first airflow channel 13 are arranged on the outer wall of the leak-proof component 18, and the capillary grooves 1521 are formed between the adjacent fins 1522. In addition, the fin 1522 abuts against the inner wall of the housing 17 to ensure that the capillary groove 1521 can absorb and store the accumulated liquid by the capillary force.
Further, the plurality of capillary grooves 1521 are spaced apart and are parallel to each other along the extension direction of the second airflow channel 151. After the capillary grooves 1521 that are relatively close to the second intersection 1512 are filled up with the accumulated liquid, the capillary grooves 1521 that are relatively far away from the second intersection 1512 continue to absorb the accumulated liquid until a storage amount of the accumulated liquid in the plurality of capillary grooves 1521 reaches saturation. In addition, after the storage amount of the accumulated liquid in the plurality of capillary grooves 1521 reaches saturation, the leak-proof component 18 is optionally detached for cleaning, so as to be used again, or the atomizer 1 is optionally replaced with a new one, which is not limited herein.
It should be noted that, a portion of the leak-proof component 18 where the second airflow channel 151 and the capillary liquid absorbing structure 152 are located may be a detachable structure. In this way, the second airflow channel 151 and the capillary liquid absorbing structure 152 can be easily assembled into the leak-proof component 18, and it is also convenient to clean the leak-proof component 18 as described above. Certainly, in other embodiments of this disclosure, the portion of the leak-proof component 18 where the second airflow channel 151 and the capillary liquid absorbing structure 152 are located and the original leak-proof component 18 may alternatively be an integral structure and cannot be disassembled or assembled, which is not limited herein.
Reference is made to FIG. 5 and FIG. 6. FIG. 5 shows a situation of accumulated liquid in the first airflow channel 31 when the frequency of the user inhaling a conventional atomizer 3 reaches 60, 90 and 120. FIG. 6 shows a situation of accumulated liquid in the first airflow channel 13 when the frequency of the user inhaling the atomizer 1 reaches 60, 90 and 120 of according to this embodiment. In addition, FIG. 6 further shows a situation in which the capillary liquid absorbing structure 152 absorbs the accumulated liquid when the frequency of the user inhaling the atomizer 1 reaches 60, 90 and 120 of according to this embodiment. It can be seen that the accumulated liquid in the first airflow channel 13 of the atomizer 1 of this embodiment is significantly reduced.
In summary, in the atomizer provided in this disclosure, a portion of the first airflow channel that is in communication with the first intersection is close to the first air outlet relative to a portion of the first airflow channel that is in communication with the second intersection along an extension direction of the first airflow channel. In this way, when the user inhales, an air flow from the first air inlet to the first air outlet is generated in the first airflow channel, and air pressure of a portion of the first airflow channel that is in communication with the second intersection is greater than air pressure at the second intersection of the second airflow channel. That is, there is a pressure difference between two sides of the second intersection, and the pressure difference between the two sides of the second intersection drives the accumulated liquid in the first airflow channel to flow into the second airflow channel through the second intersection and be absorbed by the capillary liquid absorbing structure to reduce the accumulated liquid in the first airflow channel especially at the bottom of the atomizing cavity. Therefore, the liquid leakage of the atomizer is reduced and the user experience is improved.
