In an existing electronic atomization device, e-liquid storage cotton for storing an e-liquid matrix is mounted between an upper silicone component and a lower silicone component, and then a suction nozzle is mounted at the upper silicone component.
A problem of the device is that the e-liquid storage cotton is usually in close contact with an inner wall of the e-liquid storage cavity. In a vaping process, a negative pressure is easily generated inside the e-liquid storage cavity, causing a problem of poor e-liquid guide. In an environment such as a high-temperature environment, the e-liquid storage cotton may expand, causing a problem that the e-liquid storage cotton is compressed and e-liquid leaks.

Terms used in this specification of the present disclosure herein are merely intended to describe objectives of the specific implementations, but are not intended to limit the present application. A term "and/or" used in this specification includes any or all combinations of one or more related listed items.
As shown in FIG. 1 to FIG. 12, the electronic atomization device 100 includes a suction nozzle 11, a shell 12, a bottom base 13, an e-liquid storage shell 14, an upper end cap 15, a lower end cap 16, a conveying tube 17, an e-liquid storage member 18, a heating assembly 19, and a battery cell 20. The heating assembly 19 includes a base 191 and an atomization core 192.
The suction nozzle 11 has a connection tube 111 extending downward from a mouth piece end.
Upper and lower ends of the shell 12 are open ends. The suction nozzle 11 is arranged at an upper open end of the shell 12, and the bottom base 13 is arranged at a lower open end of the shell 12.
The e-liquid storage shell 14, the upper end cap 15, and the lower end cap 16 are arranged inside the shell 12.
The e-liquid storage shell 14 is approximately cylindrical. Upper and lower ends of the e-liquid storage shell 14 are also open ends. The upper end cap 15 is arranged at or covers the upper end of the e-liquid storage shell 14, and the lower end cap 16 is arranged at or covers the lower end of the e-liquid storage shell 14.
The upper end cap 15 and the lower end cap 16 are both made of sealing materials, such as silicone.
Referring to FIG. 5, a radially extending protruding portion 151 is arranged on an outer wall of the upper end cap 15.
A portion of the upper end cap 15 located above the protruding portion 151 extends into the suction nozzle 11, and an end surface of a lower end of the suction nozzle 11 is abutted against an upper surface of the protruding portion 151 to achieve sealing. The connection tube 111 is communicated with a through hole 152 of the upper end cap 15.
In a further implementation, an accommodating groove 153 is provided in an upper surface (or a surface facing away from the e-liquid storage cavity) of the upper end cap 15. An e-liquid absorbing member A is arranged in the accommodating groove 153. The e-liquid absorbing member A is provided with a through hole for allowing air flow to pass through. In this way, the e-liquid absorbing member A can absorb a condensed e-liquid matrix in the suction nozzle 11, thus preventing the condensed e-liquid matrix from being inhaled by a user.
A portion of the upper end cap 15 located below the protruding portion 151 extends into the e-liquid storage shell 14. An outer wall of this portion of the upper end cap 15 is abutted against an inner wall of the e-liquid storage shell 14 to achieve sealing. Further, a convex block is arranged on the outer wall of this portion of the upper end cap 15, to achieve a good sealing effect together with the inner wall of the e-liquid storage shell 14. An end surface of the upper end of the e-liquid storage shell 14 is abutted against a lower surface of the protruding portion 151 to achieve sealing.
Similarly, a radially extending protruding portion 161 is arranged on an outer wall of the lower end cap 16, and a portion of the lower end cap 16 located above the protruding portion 161 extends into the e-liquid storage shell 14. An outer wall of this portion of the lower end cap 16 is abutted against the inner wall of the e-liquid storage shell 14 to achieve sealing. Further, a convex block is arranged on the outer wall of this portion of the lower end cap 16, to achieve a good sealing effect together with the inner wall of the e-liquid storage shell 14. An end surface of the lower end of the e-liquid storage shell 14 is abutted against an upper surface of the protruding portion 161 to achieve sealing.
The conveying tube 17 is located in the e-liquid storage shell 14. An upper end of the conveying tube 17 is maintained in the through hole 152 of the upper end cap 15 (that is, the upper end is connected to the upper end cap 15), and a lower end of the conveying tube 17 is accommodated in the base 191 and is abutted against an end surface of an upper end of the atomization core 192 (that is, the lower end is connected to the lower end cap 16 through the base 191). In another example, the lower end of the conveying tube 17 may be directly connected to the lower end cap 16.
Gaps defined between the inner wall of the e-liquid storage shell 14 and the outer walls of the upper end cap 15, the lower end cap 16, the base 191, and the conveying tube 17 form an e-liquid storage cavity (not shown) for storing the e-liquid matrix.
The e-liquid storage member 18 is arranged inside the e-liquid storage cavity. The e-liquid storage member 18 is configured to absorb and maintain the e-liquid matrix and is preferably made of a cotton fiber medium. A body 181 of the e-liquid storage member 18 is approximately cylindrical. The e-liquid storage member 18 has a through hole 182 through which the conveying tube 17 passes. In some embodiments, a bayonet (not shown) is formed in a side wall of the e-liquid storage member 18, so that the e-liquid storage member 18 has a shape of a C-shaped barrel, which can facilitate clamping the e-liquid storage member 18 at a periphery of the conveying tube 17.
An upper end of the e-liquid storage member 18 may keep in contact with an end surface of the lower end of the upper end cap 15, or an upper end of the e-liquid storage member 18 is at least partially spaced apart from the end surface of the lower end of the upper end cap 15 to form a cavity B. Similarly, a lower end of the e-liquid storage member 18 may keep in contact with an end surface of the upper end of the lower end cap 16, or the lower end of the e-liquid storage member 18 is at least partially spaced apart from the end surface of the upper end of the lower end cap 16 to form another cavity (not shown). In the examples of FIG. 1 to FIG. 12, the upper end of the e-liquid storage member 18 is partially spaced apart from the end surface of the lower end of the upper end cap 15 to form the cavity B, and the lower end of the e-liquid storage member 18 may keep in contact with the end surface of the upper end of the lower end cap 16. On one hand, the cavity can enlarge a volume of the e-liquid storage cavity, and on the other hand, the cavity facilitates air trapping in the e-liquid storage member 18 or release of air.
If an outer wall of the e-liquid storage member 18 is in contact with or in interference fit with the inner wall of the e-liquid storage shell 14, after the e-liquid storage member 18 absorbs the e-liquid matrix, because of air tightness of the e-liquid matrix, when the e-liquid matrix at the lower end of the e-liquid storage member 18 is consumed, a negative pressure is easily generated at the upper end of the e-liquid storage member 18, which is then not beneficial to conveying of the e-liquid matrix. To avoid this problem, in the examples of FIG. 1 to FIG. 12, on one hand, a groove 183 is further provided in the outer wall of the e-liquid storage member 18. The groove 183 is communicated to the upper and lower ends of the e-liquid storage member 18, and the groove 183 defines and forms a first air pressure balancing channel. In this way, when the negative pressure is generated at the upper end of the e-liquid storage member 18, air at the lower end of the e-liquid storage member 18 can flow upward (shown by the dashed arrow in FIG. 5) from the groove 183, so that air pressures inside and outside the e-liquid storage shell 14 is balanced, and air pressures at the upper and lower ends of the e-liquid storage member 18 are balanced through the groove 183, thereby facilitating conveying of the e-liquid matrix. In addition, due to the groove 183, a particular gap is reserved between the outer wall of the e-liquid storage member 18 and the inner wall of the e-liquid storage shell 14. In an environment such as a high-temperature environment, the gap can ensure that the e-liquid storage member 18 has a particular expansion space, which avoids a problem of e-liquid leakage caused by the e-liquid matrix flowing out from an e-liquid guide hole 191a of the atomization core 192.
In some other embodiments of the present application, the upper end cap 15 further has a through hole 154. The through hole 154 communicates an inside of the e-liquid storage shell 14 with an outside. The through hole 154 defines and forms a second air pressure balancing channel for providing a path for discharging air to an outside of the e-liquid storage cavity or supplementing air to an inside of the e-liquid storage cavity. The first air pressure balancing channel is in fluid communication with the second air pressure balancing channel through the cavity B. In some optional examples, it is also feasible that the first air pressure balancing channel is in fluid communication with the second air pressure balancing channel through the e-liquid storage member 18 (the e-liquid storage member 18 has air permeability. For example: after the e-liquid matrix absorbed by a portion of the e-liquid storage member 18 close to the upper end cap 15 flows downward, the first air pressure balancing channel and the second air pressure balancing channel are communicated to each other through this portion of the e-liquid storage member 18). In some examples, it is also feasible that the first air pressure balancing channel is in direct fluid communication with the second air pressure balancing channel. Further, as can be seen in FIG. 7 to FIG. 8, the accommodating groove 153 has a plurality of space grooves C. The space grooves C are formed by being recessed in a bottom surface of a portion of the accommodating groove 153, and the space grooves C can collect the condensed e-liquid matrix in the suction nozzle 11. An opening of one end of the through hole 154 may be arranged in one space groove C. The plurality of space grooves C are spaced apart from each other in a circumferential direction of the accommodating groove 153, which can uniformly and fully collect condensate liquid.
In an alternative embodiment, as shown in FIG. 13, a groove 183a may be formed in an inner wall of the e-liquid storage member 18. Similar to the foregoing description, the air pressures at the upper and lower ends of the e-liquid storage member 18 are balanced through the groove 183.
It should be noted that, the above groove (the groove 183 or the groove 183a) may axially extend along the outer wall or the inner wall of the e-liquid storage member 18, or may bend or spirally extend from the lower end of the e-liquid storage member 18 to the upper end of the e-liquid storage member 18 and be formed in the outer wall or the inner wall of the e-liquid storage member 18, or may not be a groove, provided that a gap is reserved between the outer wall of the e-liquid storage member 18 and the inner wall of the e-liquid storage shell 14, or between the inner wall of the e-liquid storage member 18 and the outer wall of the conveying tube 17.
In another alternative embodiment, as shown in FIG. 14, the e-liquid storage member 18 and the e-liquid storage shell 14 are both approximately cylindrical, and cross sections of both the e-liquid storage member 18 and the e-liquid storage shell 14 are annular. When a portion of the conveying tube 17 is considered, a diameter of the cross section of the e-liquid storage member 18 is d1, and a diameter of the cross section of the e-liquid storage shell 14 is d2, d1 < d2. Therefore, in any cross section in the length direction of the e-liquid storage member 18, the e-liquid storage member 18 does not completely occupy the e-liquid storage cavity, and a cross sectional area of the e-liquid storage member 18 is smaller than a cross sectional area of the e-liquid storage shell 14. In this way, a particular gap is reserved between the outer wall of the e-liquid storage member 18 and the inner wall of the e-liquid storage shell 14. Through the gap between the outer wall of the e-liquid storage member 18 and the inner wall of the e-liquid storage shell 14, the air pressures at the upper and lower ends of the e-liquid storage member 18 are balanced. Similarly, a similar gap may alternatively be formed between the inner wall of the e-liquid storage member 18 and the outer wall of the conveying tube 17.
In another alternative embodiment, as shown in FIG. 15, the e-liquid storage member 18 internally has a through hole 183c extending from the lower end of the e-liquid storage member 18 to the upper end of the e-liquid storage member 18. A shape of a cross section of the through hole 183c is not limited. For example: The cross section may be circular, elliptical, triangular, or quadrangular, or in other irregular shapes. The through hole 183c may extend or bend axially or extend spirally into the e-liquid storage member 18. Through the through hole 183c, the air pressures at the upper and lower ends of the e-liquid storage member 18 are balanced.
In still another alternative embodiment, as shown in FIG. 16, a vent tube 183d is arranged inside the groove 183. Hardness of a material of the vent tube 183d can prevent the e-liquid storage member 18 from being flattened or collapsing when the e-liquid storage member 18 expands. In this way, the air pressures at the upper and lower ends of the e-liquid storage member 18 are balanced through the groove 183 or the vent tube 183d.
It should be noted that, the vent tube 183d may be arranged in each of the gaps in the foregoing examples. That is, the vent tube 183d may be arranged between the outer wall of the e-liquid storage member 18 and the inner wall of the e-liquid storage shell 14, arranged between the inner wall of the e-liquid storage member 18 and the outer wall of the conveying tube 17, inserted in the e-liquid storage member 18, or the like.
It should be noted that, the above implementations such as the groove, the gap, the through hole, and the vent tube may be used in a combined manner.
For the through hole 154, in an alternative embodiment, it is feasible to communicate the inside of the e-liquid storage shell 14 to the outside through the through hole provided in the lower end cap 16 or the conveying tube 17. In another alternative embodiment, it is also feasible to communicate the inside of the e-liquid storage shell 14 to the outside through the gap between the upper end cap 15 and the conveying tube 17, or the gap between the lower end cap 16 and the conveying tube 17 (when the lower end of the conveying tube 17 is directly connected to the lower end cap 16), or the gap between the lower end cap 16 and the base 191 (when the lower end of the conveying tube 17 is connected to the lower end cap 16 through the base 191), or the gap between the upper end cap 15 and the e-liquid storage shell 14, or the gap between the lower end cap 16 and the e-liquid storage shell 14. Similar to the above, the foregoing through holes and the foregoing gaps may be used in a combined manner.
A lower end of the base 191 is maintained in a through hole 162 of the lower end cap 16. The base 191 internally has an accommodating cavity configured to accommodate the atomization core 192. A side wall of the base 191 has an e-liquid guide hole 191a that communicates the e-liquid storage cavity to the atomization core 192, and a sleeve (not shown) sleeves the base 191 and the conveying tube 17. The sleeve may absorb the e-liquid matrix stored in the e-liquid storage cavity and convey the e-liquid matrix to the atomization core 192 through the e-liquid guide hole 191a. In another example, the sleeve may alternatively be omitted.
The atomization core 192 is close to the lower end cap 16. The atomization core 192 includes an e-liquid guide element 1921 and a heating element 1922. The e-liquid guide element 1921 may be, for example, a cotton fiber, a metal fiber, a ceramic fiber, a glass fiber, or cellular ceramic, and is preferably made of the cotton fiber and constructed into a tubular structure extending in a longitudinal direction of the electronic atomization device 100. The heating element 1922 is a heating mesh made of a resistive material. The heating element 1922 may be arranged on an inner wall of the e-liquid guide element 1921. In other examples, the atomization core 192 may extend in a transverse direction of the electronic atomization device 100. For example: the heating element 1922 transversely passes through the base 191 after being wrapped around the e-liquid guide element 1921. The heating element 1922 is arranged in the base 191, and two ends of the e-liquid guide element 1921 may extend into the e-liquid storage cavity.
An aerosol generated by heating the atomization core 192 is conveyed from the mouth piece end of the suction nozzle 11 after passing through the conveying tube 17, the through hole 152, the through hole of the e-liquid absorbing member A, and the connection tube 111 (shown by the dashed arrow in FIG. 4), and is then inhaled by a user.
The battery cell 20 is arranged between the lower end cap 16 and the bottom base 13. The battery cell 20 provides electric power for operating the electronic atomization device 100. The battery cell 20 may be a rechargeable battery or a disposable battery. Preferably, the rechargeable battery is used.
An air inlet is provided in the bottom base 13, and air outside the electronic atomization device 100 may flow into the electronic atomization device 100 from the air inlet, and then flow into the atomization core 192 from the through hole 162 of the lower end cap 16. Further, an air flow sensor may further be arranged on the bottom base 13, and is configured to sense an inhalation action of a user, so as to start the atomization core 192.
As shown in FIG. 17, in another example, to prevent the e-liquid matrix from leaking through the through hole 154 in the upper end cap 15 because the e-liquid absorbing member A absorbs the e-liquid matrix in the e-liquid storage cavity through the through hole 154, or to prevent the e-liquid matrix from leaking through the through hole 154 in the upper end cap 15 because e-liquid absorbing member A damages an e-liquid sealing effect of the through hole 154 in the upper end cap 15, the e-liquid absorbing member A has a notch groove A1. The through hole 154 in the upper end cap 15 can be avoided through the notch groove A1.
In a further implementation, a space groove 155 is provided in the accommodating groove 153 of the upper end cap 15, and the space groove 155 is formed by a baffle plate protruding out of a bottom surface of the accommodating groove 153. An opening of one end of the through hole 154 is arranged in the space groove 155. The e-liquid absorbing member A is arranged outside the space groove 155. For example, the e-liquid absorbing member A is arranged at a transverse periphery of the space groove 155.
It should be noted that, if the through hole 154 is provided in the lower end cap 16, an e-liquid absorbing member A and a corresponding notch groove A1 may alternatively be arranged on a surface of the lower end cap 16 facing away from the e-liquid storage cavity.
As shown in FIG. 18 to FIG. 19, in another example, a plurality of space grooves D are provided in a surface of the upper end cap 15 facing the e-liquid storage cavity. The space grooves D are formed by being recessed in a partial surface of the e-liquid storage cavity. An opening of one end of the through hole 154 may be arranged in one space groove D. Adjacent space grooves D are spaced apart through convex ribs 156. In this way, the plurality of space grooves D are spaced apart in a circumferential direction of the accommodating groove 153, and are not communicated to each other, so as to be independent of each other. The plurality of space grooves D divide the surface of the upper end cap 15 facing the e-liquid storage cavity into a plurality of incoherent regions. Since they are not communicated to each other, it is difficult for the e-liquid matrix in one space groove D to enter another space groove D. Therefore, a flowing speed of the e-liquid matrix on the surface of the upper end cap 15 facing the e-liquid storage cavity can be reduced, and it is conductive to blocking the e-liquid matrix in another space groove D from entering a space groove D. Therefore, this is conductive to reducing the amount of the e-liquid matrix in the space groove D. For a space groove D in which the opening of one end of the through hole 154 is arranged, a speed and amount of the e-liquid matrix entering the space groove D can be limited, thereby helping prevent the e-liquid matrix from leaking through the through hole 154.
It should be noted that, if the through hole 154 is provided in the lower end cap 16, a plurality of space grooves D may alternatively be arranged on the surface of the lower end cap 16 facing the e-liquid storage cavity in this way, and an opening of one end of the through hole 154 may be arranged in one space groove D.
It should be noted that, the specification of the present application and the drawings thereof provide preferred embodiments of the present application. However, the present application may be implemented in various different forms, and is not limited to the embodiments described in this specification. These embodiments are not used as an additional limitation on the content of the present application, and are described for providing a more thorough and comprehensive understanding of the content disclosed in the present application. Moreover, various embodiments not listed above formed by further combining the foregoing technical features with each other are all construed as falling within the scope of the present application. Further, for a person of ordinary skill in the art, improvements or modifications may be made according to the above descriptions, and all these improvements and modifications shall fall within the protection scope of the appended claims of the present application.
