Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and more particularly to a sealing element for an electronic cigarette atomizer and an electronic cigarette atomizer. Background Technology

[0002] There are aerosol-providing articles, such as so-called electronic cigarette devices. These devices typically contain e-liquid, which is heated to atomize and produce inhalable vapor or aerosol. The e-liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). In addition to flavorings in the e-liquid...

[0003] Known electronic cigarette devices typically include a porous ceramic body with numerous micropores inside, used to absorb and conduct e-liquid. A heating element is disposed on one surface of the porous ceramic body to heat and atomize the absorbed e-liquid. The micropores within the porous body serve two purposes: firstly, as channels for the e-liquid to flow into the atomization surface; and secondly, as air exchange channels for replenishing the e-liquid reservoir from the outside to maintain pressure balance within the reservoir after e-liquid consumption. This results in bubbles being generated within the porous ceramic body when the e-liquid is heated and atomized, and these bubbles then emerge from the absorption surface and enter the reservoir.

[0004] In the known electronic cigarette devices described above, as the e-liquid in the internal reservoir is consumed, the reservoir gradually becomes under negative pressure. This, to some extent, hinders fluid transfer, reducing the amount of e-liquid that is transferred to the atomizing surface for vaporization through the microporous channels of the porous ceramic body. Specifically, in known electronic cigarette devices used during continuous inhalation, air outside the reservoir cannot easily enter the reservoir through the microporous channels of the porous ceramic body in a short time. This slows down the rate at which e-liquid is transferred to the atomizing surface. Insufficient e-liquid supply to the heating element leads to overheating, causing the e-liquid components to decompose and volatilize, producing harmful substances such as formaldehyde. Summary of the Invention

[0005] To address the problem of negative pressure forming in the e-liquid reservoir of existing electronic cigarettes during use, which affects the delivery of e-liquid, this invention provides an electronic cigarette atomizer and electronic cigarette that promotes smooth delivery of e-liquid.

[0116] To facilitate understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0117] This invention provides an electronic cigarette product for heating and atomizing a liquid matrix. In one embodiment, a conventional... Figure 1 and Figure 2Taking the flat cigarette shown as an example, the device includes an atomizer 100 for atomizing a liquid matrix and a power supply device 200 for supplying power to the atomizer 100. The power supply device 200 is also provided with conductive spring pins 210 for connecting and conducting electricity to the atomizer 100, and magnets 220 for magnetically attracting magnetic elements on the atomizer 100.

[0118] For a detailed description of the structure of atomizer 100, please refer to [link / reference]. Figure 3 and Figure 4 The exploded diagram and Figure 5 The cross-sectional schematic diagram shown includes:

[0119] The hollow cylindrical outer shell 10 has a proximal end and a distal end opposite each other in the axial direction. The proximal end is configured as the end for the user to inhale aerosol, and a mouthpiece A for the user to inhale is provided at the proximal end. The distal end is configured as the end for assembly and connection with the power supply device 200, and the distal end of the outer shell 10 is open, on which a removable end cap 20 is installed to facilitate opening the opening to install various functional components inside the outer shell 10.

[0120] See further Figures 3 to 5 As shown, the outer casing 10 has a liquid storage chamber 12 for storing a liquid matrix, a porous body 30 for drawing the liquid matrix from the liquid storage chamber 12, and a heating element 40 for heating and vaporizing the liquid matrix drawn by the porous body 30; specifically, in Figure 5 In the cross-sectional structural schematic diagram shown, the outer shell 10 is provided with a flue gas transmission pipe 11 arranged along the axial direction. The space between the outer wall of the flue gas transmission pipe 11 and the inner wall of the outer shell 10 forms a liquid storage chamber 12 for storing the liquid matrix. The first end of the flue gas transmission pipe 11, which is relatively close to the smoking port A, is connected to the airflow of the aerosol generated by the heating element 40, thereby transmitting the aerosol generated by the vaporization of the liquid matrix by the heating element 40 to the mouthpiece A for inhalation.

[0121] See Figures 3 to 5 The porous body 30 shown is configured in an embodiment to be generally, but not limited to, a blocky structure; according to a preferred design of this embodiment, it includes an arched shape having a liquid-absorbing surface 31 and an atomizing surface 32 opposite to each other along the axial direction of the outer shell 10, i.e. Figure 3 The upper and lower surfaces of the base portion of the blocky porous body 30; wherein, the liquid-absorbing surface 31 is opposite to the liquid storage cavity 12, and absorbs the liquid matrix by directly or indirectly contacting the liquid matrix in the liquid storage cavity 12; the microporous structure inside the porous body 30 then conducts the liquid matrix to the atomizing surface 32 for heating and atomization to form an aerosol, which is then released or escaped from the atomizing surface 32. Figure 5In the porous body 30 structure shown, since the liquid absorption surface 31 and the atomizing surface 32 are parallel to each other, the movement direction of the liquid matrix and aerosol in the porous body 30 is perpendicular to the plane where the atomizing surface 32 is located. The movement of aerosol and liquid matrix within the porous body 30 will be smoother, and it is easier to manufacture.

[0122] Furthermore, to facilitate assembly and fixation, in Figures 3 to 5 In the preferred embodiment shown, the porous body 30 also includes a support portion 33.

[0123] In some embodiments, the porous body 30 can be made of hard capillary structures such as porous ceramics, porous glass ceramics, and porous glass. The heating element 40 is preferably formed on the atomizing surface 32 by mixing conductive raw material powder with printing additives to form a slurry, followed by sintering after printing. This ensures that all or most of its surface is tightly bonded to the atomizing surface 32, resulting in high atomization efficiency, low heat loss, and prevention or significant reduction of dry burning. In some embodiments, the heating element 40 can be made of materials such as stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, or titanium.

[0124] See further Figures 3 to 5 To assist in the installation and fixation of the porous body 30 and the sealing of the liquid storage cavity 12, a sealing mechanism is also provided inside the outer casing 10. The sealing mechanism includes a flexible silicone sleeve 50, a rigid support frame 60, and a flexible silicone seat 70, which both seals the opening of the liquid storage cavity 12 and fixes the porous body 30 inside.

[0125] In terms of specific structure and shape, the flexible silicone sleeve 50 is generally ring-shaped, with a hollow interior to accommodate the porous body 30, and is fitted onto the porous body 30 in a flexible and tight manner.

[0126] The rigid support frame 60 holds the porous body 30, which is fitted with the flexible silicone sleeve 50. In some embodiments, it may include a generally open-ended annular shape with an internal space for accommodating and holding the flexible silicone sleeve 50 and the porous body 30.

[0127] The flexible silicone seat 70 is located at the distal end of the liquid storage cavity 12, and its shape is adapted to the cross-section of the inner contour of the outer shell 10, thereby sealing the liquid storage cavity 12 to prevent the liquid matrix from leaking out of the liquid storage cavity 12. Furthermore, in order to prevent the shrinkage and deformation of the flexible silicone seat 53 of flexible material from affecting the tightness of the seal, the rigid support frame 60 is housed within the flexible silicone seat 70 to provide support for it.

[0128] After installation, to ensure smooth transfer of the liquid matrix and output of the aerosol, the flexible silicone base 70 is provided with a first liquid guiding channel 71 for the flow of the liquid matrix, the rigid support frame 60 is provided with a corresponding second liquid guiding channel 61, and the flexible silicone sleeve 50 is provided with a third liquid guiding channel 51. During use, the liquid matrix flows sequentially through the first liquid guiding channel 71, the second liquid guiding channel 61, and the third liquid guiding channel 51 to the liquid absorption surface 31 of the porous body 30 within the flexible silicone sleeve 50, such as... Figure 5 As indicated by the middle arrow R1, it is then absorbed and transferred to the atomizing surface 32 for vaporization.

[0129] In the aerosol output structure during suction, the flexible silicone base 70 is provided with a first insertion hole 72 for the lower end of the flue gas transmission pipe 11 to be inserted, and a corresponding second insertion hole 62 is provided on the rigid support frame 60. On the side of the rigid support frame 60 opposite to one side wall of the outer casing 10, a first airflow channel 64 is provided to connect the atomizing surface 32 with the second insertion hole 62. After installation, see... Figure 6 As shown by the middle arrow R2, the aerosol generated by the heating element 40 flows through the first airflow channel 64 to the second socket 62, and then is output to the flue gas transmission pipe 11 through the first socket 72.

[0130] Further details regarding auxiliary power supply and installation structure can be found in [reference needed]. Figures 3 to 6 As shown, the end cap 20 is provided with a first support foot 21 for supporting and fixing the sealing mechanism. In practice, it rests against the lower surface of the rigid support frame 60 to support the sealing mechanism. The end cap 20 is also provided with a first mounting hole 22 and a second mounting hole 23. The first mounting hole 22 is used to install a magnetic element 25 that is magnetically attracted to the magnet 220 on the power supply device 200. The second mounting hole 23 is used to install an electrode 26, which passes through the second mounting hole 23 and rests against both ends of the heating element 40 to supply power to the heating element 40. After the atomizer 100 is connected to the power supply device 200, the electrode 26 is electrically connected to the corresponding conductive spring pin 210 on the power supply device 200. Simultaneously, the end cap 20 is also provided with an air inlet 24 for allowing external air to enter the atomizer 100 during the suction process. See [reference needed]. Figure 6 As shown in Figure R2, external air flows through the air inlet 24 to the atomizing surface 32 and carries aerosols out.

[0131] In practice, a certain distance is maintained between the atomizing surface 32 and the end cap 20, so that at least part of the atomizing surface 32 and the end cap 20 surround and form an atomizing chamber for the aerosol to escape. Of course, the atomizing chamber is in airflow communication with the air inlet 24 on the end cap 20 to allow external air to enter into the atomizing chamber; on the other hand, it is in airflow communication with the flue gas transmission pipe 11 to output the aerosol generated and escaped on the atomizing surface 32.

[0132] When a negative pressure vacuum is created inside the liquid storage chamber 12 due to the consumption of the liquid matrix, an air channel is also provided inside the atomizer 100 to ensure that the liquid matrix can still be smoothly absorbed by the porous body 30. See further details. Figures 7 to 9 As shown; the rigid support frame 60 is provided with a through hole 63 extending along the axial direction of the atomizer 100, and the through hole 63 forms the air channel for supplementing external air into the liquid storage chamber 12; after installation, the upper end of the through hole 63 is covered by the first shielding part 73 of the flexible silicone seat 70, and the lower end is exposed without shielding, and the lower end is connected to the airflow of the atomizing chamber through the gap between it and the end cap 20 or the provided channel.

[0133] The thickness and position of the first shielding portion 73 are further designed to be approximately 0.2mm to 0.5mm thick. In more advanced embodiments, the first shielding portion 73 is even thinner than other portions, making it easier for the first shielding portion 73 to deform. Furthermore, the flexible silicone base 70 is made of a material with a Shore A hardness ranging from 20A to 40A. This allows the pressure at the upper end of the first shielding portion 73 to decrease as the negative pressure within the liquid storage chamber 12 gradually increases, through fluid transmission, thereby enabling it to form... Figure 9 The upward-curving deformation shown, along with the gap in the exposed portion at the upper end of the through-hole 63, allows external air to flow along... Figure 9 As indicated by the middle arrow R3, it enters the liquid storage chamber 12 to eliminate the negative pressure.

[0134] from Figure 4 and Figure 8 and Figure 9 As can be seen, the first shielding portion 73 of the flexible silicone seat 70 is positioned close to the first liquid guiding channel 71. This reduces the bending strength of the first shielding portion 73 by creating the first liquid guiding channel 71, making it more prone to deformation. Alternatively, several through holes, grooves, notches, and recesses can be added around the first shielding portion 73 to further reduce its bending strength and make it more susceptible to warping or deformation, such as... Figure 14 As shown.

[0135] In addition to the surface shielding method that differs from the first shielding portion 73 being in close contact with the port of the through hole 63; see further... Figures 7 to 9As shown, the rigid support frame 60 is provided with a first recessed structure 65, and a through hole 651 opposite to the second insertion hole 62 is also provided in the first recessed structure 65. The through hole 651 is in airflow communication with the second insertion hole 62 and then in airflow communication with the air inlet 24 and even the outside air. Therefore, air can be introduced into the liquid storage chamber 12 through the through hole 651 to eliminate the negative pressure in the liquid storage chamber 12. In order to assist the airflow communication between the through hole 651 and the liquid storage chamber 12, the support frame 60 is provided with a ventilation groove 66, which extends from the first recessed structure 65 to the second liquid guiding channel 62. It is an air channel for the air from the flue gas transmission pipe 11 to enter the liquid storage chamber 12.

[0136] A second blocking portion 52 is provided at the upper end of the flexible silicone sleeve 50, which can extend into the first recessed structure 65. After installation, the second blocking portion 52 of the flexible silicone sleeve 50 extends upward into the first recessed structure 65 and blocks the through hole 651. Of course, it also blocks the port of the vent groove 66. Figure 8 As shown. Furthermore, when the liquid storage chamber 12 becomes negative pressure, the second shielding part 52 deforms and contracts downwards through the pressure transmission of the fluid. Figure 9 The state shown exposes a portion of the previously blocked through-hole 651 and the port of the vent 66, thereby allowing the through-hole 651 to connect with the liquid storage chamber 12 of the vent 66, thus enabling external air to flow along... Figure 9 As indicated by the middle arrow R4, the liquid enters the storage chamber 12, which reduces the negative pressure to some extent.

[0137] In terms of design, see Figure 10 As shown, the second shielding portion 52 of the flexible silicone sleeve 50 is located between the two third fluid channels 51, and its deformation is facilitated by reducing its bending strength. Simultaneously, its thickness is reduced to approximately 0.2–0.5 mm, and the material is used in the range of Shore A hardness 20A to 40A. Furthermore, to enhance its deformation tendency under lower pressure, the second shielding portion 52 itself is not planar, but rather has an undulating, wave-like shape. A second recessed structure 521, opposite in direction to the protrusion, is provided in the center of the second shielding portion 52. This second recessed structure 521 serves to reduce the thickness of the second shielding portion 52 and further reduce its bending strength, making it easier to deform.

[0138] Or in Figure 11 In another embodiment of the flexible silicone sleeve 50a shown, a plurality of second recessed structures 521a are provided on the second shielding portion 52a, which protrudes at least partially relative to the other portions, so that it is in the shape of a wave extending along the cross-sectional direction of the atomizer 100, in order to reduce the bending strength of the second shielding portion 52a and make it easier to deform.

[0139] exist Figure 12 and Figure 13 In another variable embodiment shown, an air passage is formed between the rigid support frame 60a and the flexible silicone seat 70a to allow external air to enter when the liquid reservoir 12 is under negative pressure; specifically,

[0140] In one embodiment, a groove 63a extending along the length direction is provided on the outer wall of the first end of the rigid support frame 60a along the width direction. After installation, an air channel is formed between the groove 63a and the inner wall of the flexible silicone seat 70a for air in the atomizing chamber to enter the liquid storage chamber 12. A first blocking part 73a is provided on the flexible silicone seat 70a to cover the port of the groove 63a. The first blocking part 73a can be slightly tilted or bent into the liquid storage chamber 12 when there is negative pressure inside the liquid storage chamber 12, thereby opening the port of the groove 63a.

[0141] At the same time Figure 12 and Figure 13 In the rigid support frame 60a, a protruding rib 67a extending along the length direction is provided on the outer wall of the second end along the width direction. After installation, the protruding rib 67a prevents the outer wall of the second end of the rigid support frame 60a from completely fitting with the inner wall of the flexible silicone seat 70a, thus maintaining a certain gap. This gap forms an air channel for external air to enter the liquid storage chamber 12. Of course, the first blocking part 73a opposite to the protruding rib 67a covers the port of the air channel formed by the protruding rib 67a, and when the liquid storage chamber 12 is under negative pressure, it slightly tilts or bends into the liquid storage chamber 12, thereby opening the port of the air channel formed by the protruding rib 67a.

[0142] Further in Figure 13 In the preferred embodiment shown, to facilitate the upward tilting or bending deformation of the first shielding portion 73a under negative pressure in the liquid storage chamber 12, the flexible silicone seat 70a is provided with reinforcing grooves 74a located on both sides of the first shielding portion 73a along the thickness direction. These reinforcing grooves 74a allow the first shielding portion 73a to be mostly suspended or suspended, thus making it easier to tilt or bend. In a variant implementation, the reinforcing grooves 74a can be replaced with several perforations. These perforations reduce the connection area between the first shielding portion 73a and other parts, lowering its bending strength and promoting its ease of deformation.

[0143] exist Figure 14In another preferred embodiment shown, the reinforcing structure 74b of the flexible silicone seat 70b surrounding the first shielding portion 73b can be a hole, groove, or a notch formed by extending outward from the first liquid guiding channel 71, etc., close to or surrounding the first shielding portion 73b. The purpose of these structures is to reduce the bending strength of the first shielding portion 73b, making it more prone to warping and deformation. Similarly, a recess 741b can also be provided on the first shielding portion 73b, which can also reduce the bending strength of the first shielding portion 73b.

[0144] Of course Figure 12 and Figure 14 In the preferred embodiment shown, the first shielding portions 73 / 73a form a suspended connection with the other portions of the flexible silicone seat 70 / 70a as shown in the figure through the grooves, notches and other structures surrounding them, which makes it easier to warp or bend and deform.

[0145] Or in Figure 14 and Figure 15 In another variation shown, the channel for replenishing air into the liquid storage chamber 12 is formed on the porous body 30b. Specifically... Figure 14 In the process, the porous body 30b is provided with a hole 33b that runs through the length of the atomizer 100, and the hole 33b serves as a channel for replenishing air into the liquid storage chamber 12; the corresponding flexible silicone sleeve 50b is provided with a third blocking portion 53b that extends along the cross-sectional direction of the atomizer 100 and covers the hole 33b, and the third blocking portion 53b can be deformed upward or bent in response to the negative pressure of the liquid storage chamber 12, thereby opening the hole 33b so that external air can be replenished into the liquid storage chamber 12.

[0146] Or in the above Figure 14 and Figure 15 In other variant implementations, the air channel is formed between the porous body 30b and the flexible silicone sleeve 50b, such as a groove structure on the inner wall of the porous body 30b and / or the flexible silicone sleeve 50b, etc.

[0147] Figure 17A schematic diagram of the structure of a flexible silicone seat 70c according to another alternative embodiment is shown. It has a first blocking portion 73c corresponding to the through hole 63 of the support frame 60. At least a portion of the blocking portion 73c opposite to the port of the through hole 63 forms a protrusion 731c that faces away from the through hole 63 and into the liquid storage cavity 12. Furthermore, the protrusion 731c can be cut or slit 732c formed by cutting, scratching or other means. In the non-suction state, the first blocking portion 73c itself is closed by the pressure of the liquid matrix. When the negative pressure inside the liquid storage cavity 12 gradually increases to a certain level during the suction process, the cut or slit 732c can expand and thus open the port of the through hole 63, thereby replenishing air into the liquid storage cavity 12.

[0148] Or in yet another alternative implementation, Figure 18 A schematic diagram of another atomizer 100d is shown; the through hole 63d of the support frame 60d serves as a channel for replenishing air to the liquid storage chamber 12; a flexible material blocking plug 73d is provided at the port of the through hole 63d, which is blocked by a spring element 74d with elastic force against the through hole 63d; when the negative pressure inside the liquid storage chamber 12 gradually increases to a certain level during the suction process, and the external air pressure is greater than the elastic force of the spring element 74d, the blocking plug 73d will be forced open, allowing external air to enter the liquid storage chamber 12. When the negative pressure inside the liquid storage chamber 12 drops to a certain level, the elastic force of the spring element 74d will cause the blocking plug 73d to close the through hole 63d again.

[0149] The above atomizers and electronic cigarettes utilize the flexibility of flexible silicone components to respond to the negative pressure of the liquid reservoir and generate elastic deformation, thereby opening the air channel. This allows external air to enter the liquid reservoir, partially relieving the negative pressure and ensuring smooth transfer of the liquid matrix.

[0150] Of course, in the above implementation, the flexible component itself has a certain resistance to deformation, so that when the liquid storage chamber 12 is not being pumped, the air channel inside is normally closed, and the liquid storage chamber 12 maintains a certain negative pressure. Only when the negative pressure inside the liquid storage chamber 12 increases to exceed a certain critical threshold during the pumping process, the flexible component responds to the above negative pressure change and deforms to allow air to enter. In this way, it can prevent the oil storage chamber 12 from being in a constant atmospheric pressure state and avoid the liquid matrix from directly leaking through the porous body 30.

[0151] Further in Figure 19 The illustrated embodiment proposes a structure with a porous body 30c and a flexible silicone sleeve 50c that provides a better sealing effect and prevents leakage of liquid matrix between the joints of the components; specifically,

[0152] Porous body 30c includes:

[0153] The base portion 310c, which extends along the cross-sectional direction of the atomizer 100, can have its upper and lower surfaces used as the liquid absorption surface and atomizing surface as described above, respectively.

[0154] First extension arm 320c and second extension arm 330c; formed by the base portion 310c extending upward along the length direction of the atomizer 100; in Figure 19 In the preferred embodiment shown, the first extension arm 320c and the second extension arm 330c are respectively disposed on opposite sides of the base portion 310c along the thickness direction of the atomizer 100.

[0155] Further in Figure 19 In the preferred embodiment shown, the porous body 30c further includes a support portion 340c extending along the cross-sectional direction of the atomizer 100 between the first extension arm 320c and the second support portion 320c.

[0156] The flexible silicone sleeve 50c is generally hollow and cylindrical, wrapping around the porous body 30c.

[0157] The outer surface of the flexible silicone sleeve 50c is provided with several raised ribs to improve the sealing effect after installation. These ribs mainly seal the liquid matrix transfer channel between the support frame 60 and the porous body 30c, preventing leakage through the gaps between the support frame 60 and the porous body 30c during liquid transfer. Therefore, in implementation, the several raised ribs together form a closed ring, completely surrounding or enclosing the liquid transfer channel, thereby achieving a better sealing effect. Specifically, this includes:

[0158] The first rib 510c consists of two segments, which are respectively disposed on the two outer side walls of the flexible silicone sleeve 50c along the width direction; and in the figure, the first rib 510c extends along the thickness direction.

[0159] Furthermore, in the assembled position, the first protruding rib 510c corresponds to or overlaps with the base portion 310c of the porous body 30c, thereby enabling the first protruding rib 510c to be supported by the base portion 310c and to tightly abut against the inner wall of the support frame 60.

[0160] The second rib 520c consists of two segments, which are respectively set on the top wall surface of the flexible silicone sleeve 50c on both sides near the thickness direction. In the figure, it is constructed to extend along the width direction and is positioned opposite the support portion 340c. After installation, the support portion 340c can provide support so that the second rib 520c can tightly abut against the inner wall of the support frame 60.

[0161] The third rib 530c comprises four segments, specifically disposed on the two outer side walls of the flexible silicone sleeve 50c along its thickness direction (the two opposite segments of the third rib 530c are obscured and not shown in the figure); and has a first end connected to the first rib 510c and a second end connected to the second rib 520c along its length direction. After installation, the third rib 530c is supported by the outer side walls of the first extension arm 320c and the second extension arm 330c, so that the third rib 530c abuts tightly against the inner wall of the support frame 60.

[0162] according to Figure 19 In a preferred embodiment, the third rib 530c has four segments, which are then connected to form a closed shape by means of the first rib 510c, the second rib 520c, and the third rib 530c disposed on the flexible silicone sleeve 50c. Of course, the closed shape formed by the ribs is a non-planar closed loop with a span along the length direction of the atomizer 100.

[0163] At the same time, according to Figure 19 In the preferred embodiment, the third rib 530c is inclined outward along the width direction.

[0164] Further in Figure 19 In the preferred embodiment shown, the flexible silicone sleeve 50c is provided with a receiving hole 540c located between two opposing second ribs 520c. In this embodiment, the receiving hole 540c is opposite to the through hole 651 on the rigid support frame 60, so that the condensate of the aerosol transmitted in the flue gas transmission pipe 11 can fall downward and be received and absorbed by the support part 340c through the receiving hole 540c.

[0165] Figure 20 A schematic diagram of another optional embodiment of the flexible silicone sleeve 50d with raised ribs to improve the sealing effect is presented. In this embodiment, there are two mutually separated and each closed annular raised ribs; specifically:

[0166] A first closed loop is formed by a first protruding rib 510d disposed on a side wall in a width direction, a second protruding rib 520d disposed on the top, and two third protruding ribs 530d located on two side walls in the thickness direction.

[0167] Similarly, it also includes a second closed loop composed of another fourth rib 511d, a fifth rib 521d, and two sixth ribs 531d.

[0168] Of course, the closed rings formed by the above-mentioned ribs are independent of each other and are symmetrically arranged on the flexible silicone sleeve 50d along the width and thickness directions.

[0169] exist Figure 20In the preferred embodiment shown, the rib structure arrangement has two symmetrical closed rings, each surrounding one of the two fluid communication ports 51d, thereby preventing leakage from the gap between the support frame 60 and the porous body 30c during the transfer of the liquid matrix.

[0170] And according to Figure 20 In the preferred embodiment shown, the flexible silicone sleeve 50d has channel portions 540d formed by recesses on both sides along its thickness direction, which provide aerosol output during suction, forming part of the airflow path R2 during suction. The third rib 530d and the sixth rib 531d are respectively arranged on both sides of this channel portion 540d.

[0171] Further according to Figure 19 and Figure 20 In the preferred embodiment shown, the extension path of the formed closed annular rib completely passes through the entire outer surface of the flexible silicone sleeve 50c / 50d, that is, a portion of the closed ring extends on the left and right outer side walls along the width direction, the front and rear outer side walls along the thickness direction, and the outer surface of the top wall of the flexible silicone sleeve 50c / 50d.

[0172] exist Figure 21 In another alternative embodiment shown, of the two closed annular ribs of the flexible silicone sleeve 50e, the second rib 520e comprises two parts that are at a certain angle to each other; the corresponding fifth rib 521e similarly has two parts that are at a certain angle to each other.

[0173] Of course, in that Figure 21 In the flexible silicone sleeve 50e shown, the second rib 520e and the fifth rib 521e are both supported by the support portion 340c.

[0174] And in that Figure 21 The flexible silicone sleeve 50e shown in the embodiment Figure 21 Two closed rings formed by several convex ribs connected in sequence can be connected.

[0175] At the same time, in the above Figures 19 to 21 In the preferred embodiment shown, the above-mentioned ribs are symmetrically arranged along the thickness or width direction of the atomizer 100.

[0176] The above electronic cigarette atomizer adopts a structure that is compatible with the porous body 30 / 30c with the support part 33 / 340c. The flexible silicone sleeve 50c / 50d / 50e is provided with ribs that correspond to each part of the porous body 30 / 30c. This allows the porous body 30 / 30c to be tightly abutted against the rigid support frame 60 / 60a after assembly, thus isolating the liquid channel and improving the sealing effect.

[0177] It should be noted that the preferred embodiments of the present invention are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
