Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to a Chinese patent application filed with the China Patent Office on November 4, 2022, bearing application number 202222958406.3 and entitled "Electronic Atomization Device," and to an earlier application filed with the China State Intellectual Property Office on November 4, 2022, bearing application number 202211378895.3 and entitled "Electronic Atomization Device," the entire contents of which are incorporated herein by reference.

[0002] TECHNICAL FIELD This application relates to the technical field of electronic atomization, and in particular to electronic atomization devices. [Background technology]

[0003] An electronic atomizer is an electronic product that atomizes a liquid matrix to generate an aerosol that can be inhaled by the user. Conventional electronic atomizers typically have a liquid storage pad for storing the liquid matrix attached between two upper and lower silica gel members, and a suction nozzle attached to the upper silica gel member.

[0004] The problem with this device is that the liquid storage cotton and the inner wall of the liquid storage cavity are usually in close contact with each other. During suction, negative pressure is easily generated inside the liquid storage cavity, resulting in poor liquid flow. Furthermore, in high temperature environments, the liquid storage cotton expands, compressing the liquid storage cotton and causing liquid leakage. Summary of the Invention

[0006] In another aspect, the present application provides an electronic atomization device for atomizing a liquid matrix to generate an aerosol, the device comprising: a liquid storage housing having a liquid storage cavity formed therein; a liquid storage member disposed within the liquid storage cavity, the liquid storage member including a medium for adsorbing and holding a liquid matrix, the liquid storage member having a first end and a second end opposite the first end, and a groove extending from the first end to the second end on an outer wall or an inner wall; a second air pressure balance passage in fluid communication with the groove, for providing a path for air to be discharged to the outside of the liquid storage cavity or for air to be replenished inside the liquid storage cavity.

[0007] In another aspect, the present application provides an electronic atomization device for atomizing a liquid matrix to generate an aerosol, the device comprising: a liquid storage housing having a liquid storage cavity formed therein; a liquid storage member disposed within the liquid storage cavity, containing a medium for adsorbing and retaining a liquid matrix, and having a first end and a second end opposite to the first end, wherein the cross-sectional area of ​​the liquid storage member in any cross section in the length direction of the liquid storage member is smaller than the cross-sectional area of ​​the liquid storage cavity, and a first air pressure balance passage is formed penetrating between the first end and the second end of the liquid storage member; The electronic atomization device further includes a second air pressure balance passage in fluid communication with the first air pressure balance passage for providing a path for air to be exhausted to the outside of the liquid storage cavity or for air to be replenished inside the liquid storage cavity.

[0008] The electronic atomizer provided above can balance the air pressure at both ends of the liquid storage member and the air pressure inside and outside the liquid storage housing through the air pressure balancing passage, thereby avoiding the problem of poor liquid flow caused by negative pressure inside the liquid storage housing and improving the user's inhalation experience.

In order to facilitate understanding of the present application, the present application will be described in more detail below with reference to the drawings and specific embodiments. It should be noted that when an element is described as being "fixed" to another element, it may be directly located on the other element, or there may be one or more intervening elements between them. When an element is described as being "connected" to another element, it may be directly connected to the other element, or there may be one or more intervening elements between them. The terms "upper," "lower," "left," "right," "inner," "outer," and similar expressions used herein are for illustrative purposes only.

[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. As used herein, the terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit the scope of this application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0013] 1 to 12, the electronic atomization device 100 includes a suction nozzle 11, an outer housing 12, a base 13, a liquid storage housing 14, an upper end cap 15, a lower end cap 16, a transport tube 17, a 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.

[0014] The suction nozzle 11 has a connecting pipe 111 extending downward from the opening end.

[0015] Both the upper and lower ends of the outer housing 12 are open ends. The suction nozzle 11 is provided at the upper open end of the outer housing 12, and the base 13 is provided at the lower open end of the outer housing 12.

[0016] A liquid reservoir housing 14 , an upper end cap 15 and a lower end cap 16 are disposed within the outer housing 12 .

[0017] The liquid storage housing 14 is generally cylindrical. Both the top and bottom ends of the liquid storage housing 14 are open. An upper end cap 15 is provided on the upper end of the liquid storage housing 14 or covers the upper end of the liquid storage housing 14, and a lower end cap 16 is provided on the lower end of the liquid storage housing 14 or covers the lower end of the liquid storage housing 14.

[0018] Both the upper end cap 15 and the lower end cap 16 are made of a sealing material such as silica gel.

[0019] Referring to FIG. 5, the outer wall of the upper end cap 15 has a protrusion 151 extending in the radial direction.

[0020] The partial upper end cap 15 located above the protrusion 151 is inserted into the suction nozzle 11, and the end face of the lower end of the suction nozzle 11 abuts against the upper surface of the protrusion 151 to form a seal. The connecting pipe 111 communicates with the through hole 152 of the upper end cap 15.

[0021] In a further embodiment, the upper surface of the upper end cap 15 (or the surface opposite to the liquid storage cavity) has a receiving groove 153 in which a liquid-absorbing member A having a through-hole through which an airflow passes is provided, so that the liquid-absorbing member A can suck up the condensed liquid matrix in the suction nozzle 11 and further prevent the condensed liquid matrix from being inhaled by the user.

[0022] The partial upper end cap 15 located below the protrusion 151 is recessed into the liquid storage housing 14. The outer wall of this partial upper end cap 15 abuts against the inner wall of the liquid storage housing 14 to form a seal, and the outer wall of this partial upper end cap 15 has bumps to form a good seal with the inner wall of the liquid storage housing 14. The end face of the upper end of the liquid storage housing 14 abuts against the underside of the protrusion 151 to form a seal.

[0023] Similarly, the outer wall of the lower end cap 16 has a radially extending protrusion 161, and the partial lower end cap 16 located above the protrusion 161 extends into the liquid storage housing 14. The outer wall of this partial lower end cap 16 abuts against the inner wall of the liquid storage housing 14 to form a seal, and the outer wall of this partial lower end cap 16 has a bump, which forms a good seal with the inner wall of the liquid storage housing 14. The end face of the lower end of the liquid storage housing 14 abuts against the upper surface of the protrusion 161 to form a seal.

[0024] The transport pipe 17 is located within the liquid storage housing 14. The upper end of the transport pipe 17 is held within the through-hole 152 of the upper end cap 15 (i.e., connected to the upper end cap 15), and the lower end of the transport pipe 17 is housed within the base 191 and abuts against the end surface of the upper end of the atomizing core 192 (i.e., connected to the lower end cap 16 via the base 191). In another example, the lower end of the transport pipe 17 may be directly connected to the lower end cap 16.

[0025] The gap between the inner wall of the liquid storage housing 14, the upper end cap 15, the lower end cap 16, the base 191, and the outer wall of the transport tube 17 defines a liquid storage cavity (not shown) for storing the liquid matrix.

[0026] The liquid storage member 18 is disposed within the liquid storage cavity. The liquid storage member 18 is adapted to adsorb and retain the liquid matrix and is preferably made of a cotton fiber medium. The body 181 of the liquid storage member 18 is generally cylindrical. The liquid storage member 18 has a through-hole 182 through which the transport tube 17 passes. In some embodiments, a locking hole (not shown) is formed in the side wall of the liquid storage member 18, thereby forming the liquid storage member 18 into a C-shaped tube, which can be easily attached to the outer periphery of the transport tube 17.

[0027] The upper end of the liquid storage member 18 may maintain contact with the lower end surface of the upper end cap 15, or may be at least partially spaced apart from the lower end surface of the upper end cap 15 to form a cavity B. Similarly, the lower end of the liquid storage member 18 may maintain contact with the upper end surface of the lower end cap 16, or may be at least partially spaced apart from the upper end surface of the lower end cap 16 to form another cavity B (not shown). In the example of FIGS. 1 to 12, the upper end of the liquid storage member 18 is at least partially spaced apart from the lower end surface of the upper end cap 15 to form cavity B, but the lower end of the liquid storage member 18 may maintain contact with the upper end surface of the lower end cap 16. The cavity described above can increase the volume of the liquid storage cavity while also facilitating the release of air or gas trapped within the liquid storage member 18.

[0028] If the outer wall of the liquid storage member 18 and the inner wall of the liquid storage housing 14 maintain contact or are tightly fitted together, after the liquid storage member 18 absorbs the liquid matrix, the liquid matrix is ​​consumed at the lower end of the liquid storage member 18 due to the impermeability of the liquid matrix, which can easily create negative pressure at the upper end of the liquid storage member 18, further hindering the transport of the liquid matrix. To avoid this problem, in the example shown in Figures 1 to 12, the outer wall of the liquid storage member 18 further includes a groove 183 that connects the upper and lower ends of the liquid storage member 18 and defines a first air pressure balance passage. In this way, if negative pressure is created at the upper end of the liquid storage member 18, air at the lower end of the liquid storage member 18 can flow upward through the groove 183 (as shown by the dashed arrows in Figure 5), maintaining the balance of air pressure inside and outside the liquid storage housing 14. The groove 183 also maintains the balance of air pressure at the upper and lower ends of the liquid storage member 18, further benefiting the transport of the liquid matrix. In addition, the groove 183 provides a certain gap between the outer wall of the liquid storage member 18 and the inner wall of the liquid storage housing 14. In high temperature environments, this gap ensures that the liquid storage member 18 has a certain expansion space, thereby preventing the liquid matrix from leaking out of the liquid guide hole 191a of the atomizing core 192 and causing liquid leakage.

[0029] In some other embodiments of the present application, the upper end cap 15 further includes a through hole 154, which connects the interior of the liquid storage housing 14 with the outside, defines a second air pressure balance passage, and provides a path for air to be discharged to the outside of the liquid storage cavity or for air to be replenished within the liquid storage cavity. The first and second air pressure balance passages are in fluid communication with each other through the cavity B. In some alternative examples, the first and second air pressure balance passages may be in fluid communication with each other through the liquid storage member 18 (the liquid storage member 18 itself is permeable, and for example, when the liquid matrix absorbed in the portion of the liquid storage member 18 close to the upper end cap 15 flows downward, the first and second air pressure balance passages are in fluid communication with each other through this portion of the liquid storage member 18). In some examples, the first and second air pressure balance passages may be in direct fluid communication with each other. Furthermore, as can be seen from Figures 7 and 8, the storage groove 153 has multiple space grooves C, each formed by a recess in part of the bottom surface of the storage groove 153, and the space grooves C can collect the condensed liquid matrix in the suction nozzle 11.The opening at one end of the through hole 154 can be provided in one of the space grooves C, and the multiple space grooves C are spaced apart from each other in the circumferential direction of the storage groove 153, allowing the condensed liquid to be collected uniformly and sufficiently.

[0030] 13, a groove 183a may be formed in the inner wall of the liquid storage member 18. As described above, the groove 183 maintains balance of the air pressure at the upper and lower ends of the liquid storage member 18.

[0031] It should be noted that the above-mentioned groove (groove 183 or groove 183a) may extend axially along the outer or inner wall of the liquid storage member 18, or may extend curvedly or spirally from the lower end of the liquid storage member 18 to the upper end of the liquid storage member 18 and be formed on the outer or inner wall of the liquid storage member 18, or it does not have to be a groove, as long as there is a certain gap between the outer wall of the liquid storage member 18 and the inner wall of the liquid storage housing 14, or between the inner wall of the liquid storage member 18 and the outer wall of the transport pipe 17.

[0032] In another alternative embodiment, as shown in FIG. 14, both the liquid storage member 18 and the liquid storage housing 14 are substantially cylindrical, and the cross-sections of both the liquid storage member 18 and the liquid storage housing 14 are annular. Considering the portion of the transport pipe 17, the diameter of the cross-section of the liquid storage member 18 is d1, the diameter of the cross-section of the liquid storage housing 14 is d2, and d1 < d2. Therefore, in any cross-section in the longitudinal direction of the liquid storage member 18, the liquid storage member 18 does not completely occupy the liquid storage cavity, and the cross-sectional area of the liquid storage member 18 is smaller than the cross-sectional area of the liquid storage housing 14. In this way, there is a certain gap between the outer wall of the liquid storage member 18 and the inner wall of the liquid storage housing 14. The gap between the outer wall of the liquid storage member 18 and the inner wall of the liquid storage housing 14 maintains the air pressure balance at both the upper and lower ends of the liquid storage member 18. Similarly, a similar gap can also be formed between the inner wall of the liquid storage member 18 and the outer wall of the transport pipe 17.

[0033] In yet another alternative embodiment, as shown in FIG. 15, the liquid storage member 18 has a through hole 183c extending from the lower end to the upper end of the liquid storage member 18. The cross-sectional formation of the through hole 183c is not limited, and for example, it may be circular, elliptical, triangular, quadrangular, or other irregular shapes. The through hole 183c may extend axially, bend, or extend spirally within the liquid storage member 18. The through hole 183c further maintains the air pressure balance at both the upper and lower ends of the liquid storage member 18.

[0034] In yet another alternative embodiment, as shown in FIG. 16, a ventilation pipe 183d is provided in the concave groove 183. Regarding the hardness of the material of the ventilation pipe 183d, it is only necessary to avoid being crushed or falling off due to the expansion of the liquid storage member 18. In this way, the concave groove 183 or the ventilation pipe 183d maintains the air pressure balance at both the upper and lower ends of the liquid storage member 18.

[0035] It should be noted that any of the gaps in the above examples may be provided with a vent pipe 183d, i.e., the vent pipe 183d may be provided between the outer wall of the liquid storage member 18 and the inner wall of the liquid storage housing 14, between the inner wall of the liquid storage member 18 and the outer wall of the transport pipe 17, or inserted into the liquid storage member 18.

[0036] It should be noted that the above embodiments of grooves, gaps, holes, vent tubes, etc. can be used in combination.

[0037] Regarding the through hole 154, in an alternative embodiment, the inside of the liquid storage housing 14 may be connected to the outside via a through hole opened in the lower end cap 16 or the transport pipe 17. In another alternative embodiment, the inside of the liquid storage housing 14 may be connected to the outside via a gap between the upper end cap 15 and the transport pipe 17, or a gap between the lower end cap 16 and the transport pipe 17 (when the lower end of the transport pipe 17 is directly connected to the lower end cap 16), or a gap between the lower end cap 16 and the base 191 (when the lower end of the transport pipe 17 is connected to the lower end cap 16 via the base 191), or a gap between the upper end cap 15 and the liquid storage housing 14, or a gap between the lower end cap 16 and the liquid storage housing 14. As described above, the above-mentioned through holes and gaps may be used in combination.

[0038] The lower end of the base 191 is held in the through hole 162 of the lower end cap 16. The base 191 has a cavity for accommodating the atomizing core 192. The side wall of the base 191 has a liquid guide hole 191a that connects the liquid storage cavity with the atomizing core 192, and a sleeve (not shown) is fitted over the base 191 and the transport pipe 17. The sleeve can suck in the liquid matrix stored in the liquid storage cavity and transport it to the atomizing core 192 through the liquid guide hole 191a. In another example, the sleeve may be omitted.

[0039] The atomizing core 192 is located near the lower end cap 16. The atomizing core 192 includes a liquid-guiding element 1921 and a heating element 1922. The liquid-guiding element 1921 may be made of, for example, cotton fiber, metal fiber, ceramic fiber, glass fiber, porous ceramic, etc., but is preferably made of cotton fiber and has a tubular structure extending in the vertical direction of the electronic atomizing device 100. The heating element 1922 is a heat-generating mesh made of a resistive material. The heating element 1922 may be located on the inner wall of the liquid-guiding element 1921. In another example, the atomizing core 192 may be arranged to extend in the horizontal direction of the electronic atomizing device 100. For example, the heating element 1922 may be wound around the liquid-guiding element 1921 and then pass laterally through the base 191, but the heating element 1922 may be located within the base 191, and both ends of the liquid-guiding element 1921 may extend into the liquid storage cavity.

[0040] The aerosol generated by heating the atomizing core 192 passes through the transport tube 17, the through hole 152, the through hole of the liquid-absorbing member A, and the connecting tube 111 (as shown by the dashed arrow in Figure 4), and is then sent from the mouth end of the suction nozzle 11 and is then inhaled by the user.

[0041] The battery cell 20 is disposed between the lower end cap 16 and the base 13. The battery cell 20 provides power for operating the electronic atomization device 100. The battery cell 20 may be a rechargeable battery or a disposable battery. A rechargeable battery is preferably used.

[0042] The base 13 is provided with an air intake port, through which air from outside the electronic atomization device 100 can flow into the electronic atomization device 100 and then into the atomization core 192 through the through-hole 162 in the lower end cap 16. Furthermore, the base 13 may be provided with an airflow sensor to detect the user's inhalation and activate the atomization core 192.

[0043] As shown in FIG. 17 , in another example, the liquid-absorbing member A has a notch groove A1 that can avoid the through-holes 154 of the upper end cap 15, so as to prevent the liquid matrix from leaking through the through-holes 154 of the upper end cap 15 by absorbing the liquid matrix in the liquid storage cavity through the through-holes 154, or to prevent the liquid matrix from leaking through the through-holes 154 of the upper end cap 15 by destroying the liquid sealing effect of the through-holes 154 of the upper end cap 15.

[0044] In a further embodiment, the accommodation groove 153 of the upper end cap 15 is provided with a space groove 155 constituted by a baffle protruding from the bottom surface of the accommodation groove 153. The opening of one end of the through hole 154 is provided within the space groove 155, and the liquid-absorbing member A is provided outside the space groove 155; for example, the liquid-absorbing member A is provided on the outer periphery of the space groove 155 in the lateral direction.

[0045] It should be noted that if the through holes 154 are provided in the lower end cap 16, the surface of the lower end cap 16 opposite the liquid storage cavity may also be provided with a liquid absorbing member A and a corresponding notched groove A1.

[0046] 18 and 19, in another example, the surface of the upper end cap 15 facing the liquid storage cavity has a plurality of space grooves D formed by recessing a portion of the surface of the liquid storage cavity, and the opening of one end of the through hole 154 can be located in one of the space grooves D. Adjacent space grooves D are spaced apart by protruding ribs 156. Thus, the plurality of space grooves D are spaced apart from one another in the circumferential direction of the receiving groove 153 and do not communicate with one another, making them independent of one another. The plurality of space grooves D divide the surface of the upper end cap 15 facing the liquid storage cavity into a plurality of discontinuous sections that do not communicate with one another, making it difficult for the liquid matrix in one space groove D to enter another space groove D. This reduces the flow rate of the liquid matrix on the surface of the upper end cap 15 facing the liquid storage cavity and helps to block the liquid matrix in other space grooves D from entering one space groove D, thereby helping to reduce the amount of liquid matrix in that space groove D. For one of the space grooves D where an opening at one end of the through hole 154 is provided, the speed and amount of the liquid matrix entering the space groove D is limited, which helps to prevent leakage of the liquid matrix through the through hole 154.

[0047] It should be noted that when the through hole 154 is provided in the lower end cap 16, a plurality of space grooves D can also be provided in the surface of the lower end cap 16 facing the liquid storage cavity, and the opening at one end of the through hole 154 can be provided in one of the space grooves D.

[0048] It should be noted that although the specification and drawings of this application show preferred embodiments of the present application, the present application can be realized in many different forms and is not limited to the embodiments described herein, and these embodiments do not further limit the content of the present application. The purpose of providing these embodiments is to make the disclosure of this application more complete and comprehensive. In addition, various embodiments not listed above in which the above technical features are further combined with each other are also considered to be within the scope of the description of this application. Furthermore, those skilled in the art may make improvements and modifications based on the above description, and all such improvements and modifications are intended to fall within the scope of the appended claims.
