The buffer element flows liquid to the liquid guiding element through the liquid inlet hole, and the liquid guiding efficiency of the buffer element is lower than that of the liquid guiding element.

[0006] In one embodiment, the isolation member includes a mounting seat, a first partition seal and a second partition seal. On the side of the mounting seat facing away from the liquid storage chamber, the second partition seal encloses the end of the mounting seat to form a mounting chamber in the mounting seat. The first partition seal is arranged on the side of the mounting seat close to the liquid storage chamber. The atomization core and the buffer member are arranged in the mounting chamber. The mounting seat is located at the bottom wall of one end of the mounting chamber close to the liquid storage chamber and is provided with a connecting hole and at least one of the lower liquid channels.

The more the buffer member extends, the longer the atomization matrix penetrates, the slower the saturation rate of the atomization core, and thus the lower the probability of leakage. At the same time, the buffer member has a larger volume and a stronger liquid storage capacity, which further reduces the liquid outlet pressure of the atomization core and better reduces the probability of leakage of the atomization core; furthermore, the layout of the upper liquid storage chamber and the lower atomization assembly can effectively improve the utilization rate of the internal space of the shell.

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some, rather than all, structures related to the present application are shown in the drawings. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] Existing products have the problem of the atomization matrix penetrating the atomization core too quickly, causing oil leakage.

[0030] In the present application, a buffer is added to the outside of the atomizer core, and the buffer serves as an intermediary for the atomizer matrix to penetrate into the atomizer core. The buffer extends further away from the atomizer core and reaches directly below the liquid storage chamber. In this way, the buffer maximizes the length of the route for the atomizer matrix to penetrate into the atomizer core and the buffer intercepts more atomizer matrix, thereby preventing the atomizer core from absorbing a saturated amount of atomizer matrix too quickly and causing leakage.

[0031] Figure 1 is a cross-sectional view of an embodiment provided by the present application; Figure 2 yes Figure 1 Enlarged view of point A in the middle; Figure 4 yes Figure 1 Cross-sectional view of the atomization assembly.

[0032] This application provides an atomizing device, see Figure 1 、 Figure 2 and Figure 4 , a shell 10, in which a chamber 11 is provided.

[0033] The atomizing assembly 20 includes an atomizing core 21 , a buffer 22 and an isolating member 23 .

[0034] The isolation member 23 is arranged in the chamber 11 and partially divides the chamber 11 to form a liquid storage chamber 111. In the axial direction of the atomizer device, the projection of the liquid storage chamber 111 covers the projection of the isolation member 23. The isolation member 23 is provided with at least one lower liquid channel 40, and the lower liquid channel 40 passes through the isolation member 23 in the axial direction of the atomizer device.

[0035] The atomizer core 21 is disposed in the chamber 11 and is located on a side of the isolation member 23 away from the liquid storage chamber 111 .

[0036] The buffer member 22 is housed in the isolation member 23 and acts on the atomizer core 21 . In the axial direction of the atomizer device, the projection of the lower liquid channel 40 covers at least a portion of the projection of the buffer member 22 .

[0037] The housing 10 defines a chamber 11 therein.

[0038] The atomizer assembly 20 includes an atomizer core 21, a buffer 22 and an isolator 23. At least one lower liquid channel 40 is provided on the isolator 23. The isolator 23 is arranged in the chamber 11 and partially divides the chamber 11 to form a liquid storage chamber 111. In the axial direction of the atomizer device, the projection of the liquid storage chamber 111 covers the projection of the isolator 23 and the buffer 22.

[0039] The lower liquid channel 40 penetrates the partition 23 in the axial direction of the atomizing device.

[0040] The atomizer core is disposed in the chamber 11 and is located on a side of the isolation member 23 facing away from the liquid storage chamber 11 .

[0041] The buffer member 22 acts on the atomizer core 21 . In the axial direction of the atomizer device, the projection of the lower liquid channel 40 covers at least a portion of the projection of the buffer member 23 .

[0042] Among them, the shell 10, according to the existing technology, is generally cylindrical; in this embodiment, the cross-section of the shell 10 in the width direction is elliptical. In addition, the middle part of the shell 10 is a hollow structure, thereby forming an internal chamber 11. An atomizing tube is passed through the middle of the chamber 11, and an atomizing channel 30 is formed in the middle of the atomizing tube. The atomizing tube is arranged along the length direction of the shell 10. Specifically, one end of the atomizing channel 30 is connected to one end outside the shell 10, and the other end is located inside the shell 10. In addition, a shell 101 can be set outside the shell 10, and the shell 101 and the shell 10 form a double layer of protection.

[0043] The atomizer core 21 is disposed in the chamber 11 and is located on a side of the isolation member 23 away from the liquid storage chamber 111 , and is connected in series with the atomization channel 30 .

[0044] The isolator 23 can be in a sheet shape and have an inner cross-section that matches the width of the housing 10. In this embodiment, the isolator 23 is disposed in the chamber 11 and is sleeved onto the atomizing channel 30. Thus, a connecting hole 50 is provided in the middle of the isolator 23 for sleeved onto the atomizing channel 30. The lower liquid channel 40 is a through hole that extends through the isolator 23 in the axial direction of the atomizing device (i.e., the axial direction of the housing 10).

[0045] The buffer 22 can be made of, but is not limited to, cotton or foam. For example, it can be oil-storage cotton, which not only slows down the flow of the atomized matrix toward the atomizer core 21 but also serves to store the atomized matrix. The buffer 22 is disposed around the atomizer core 21.

[0046] See also Figure 1 The end of the shell 10 where the atomizing channel 30 is connected to the outside of the shell 10 is the upper end of the shell 10. Except for the atomizing channel 30, the other positions of the end are closed, and the other end is the open lower end.

[0047] The isolator 23 enters the housing 10 from the lower end of the housing 10. The connection hole 50 of the isolator 23 in the housing 10 is sleeved on the outer wall of the atomization channel 30, and the outer peripheral side wall of the isolator 23 is in contact with the inner wall of the housing 10. As a result, a liquid storage chamber 111 is formed between the isolator 23, the inner wall of the housing 10, and the outer wall of the atomization channel 30. This liquid storage chamber 111 is located at the top of the entire chamber 11. In other words, in the axial direction of the atomization device, the projection of the liquid storage chamber 111 covers the projection of the isolator 23 and the buffer member 22. That is, in the direction of gas outlet along the atomization channel 30, the chamber 11 forms the liquid storage chamber 111 above the isolator 23.

[0048] The lower liquid channel 40 on the separator 23 now runs through the upper and lower ends of the separator 23. The atomizer core 21 is connected in series to the bottom end of the atomizer channel 30. The atomizer core 21 is located on the side of the separator 23 facing away from the liquid storage chamber 111. The buffer member 22 surrounds the atomizer core 21. Importantly, the buffer member 22 extends away from the center of the atomizer core 21, ultimately partially located at the lower end of the lower liquid channel 40 and directly below the liquid storage chamber 111. In other words, in the axial direction of the atomizer device, the projection of the lower liquid channel 40 covers at least a portion of the projection of the buffer member 22.

[0049] In addition, the side wall of the liquid storage chamber 111 and the side wall of the corresponding position of the shell 101 can be set to a transparent material to facilitate observation of the amount of atomized matrix in the liquid storage chamber 111; in addition, in order to facilitate the injection of atomized matrix into the liquid storage chamber 111, an oil filling port is set on the side wall of the liquid storage chamber 111, and the oil filling port is sealed by an oil filling silicone plug.

[0050] In particular, the lower liquid channel 40 can be opened at a position as far away from the atomizer core 21 as possible.

[0051] According to the above, the liquid storage chamber 111 is used to inject the atomized matrix, and the atomized matrix flows from the lower liquid channel 40 to the buffer 22. After passing through the buffer 22, the atomized matrix flows to the atomizing core 21 for atomization, and the atomized smoke is discharged from the upper end of the atomizing channel 30.

[0052] It can be seen that the arrangement of the upper liquid storage chamber and the lower buffer member 22 of this embodiment allows the atomized substrate to flow only from the top of the buffer member 22, effectively controlling the flow rate of the atomized substrate. Secondly, the buffer member 22 extends away from the atomizer core 21, which prolongs the travel distance of the atomized substrate from the lower liquid channel 40 to the buffer member 22 and then to the atomizer core 21, thereby preventing the atomizer core 21 from rapidly saturating at a high speed and thus preventing leakage from the atomizer core 21. Furthermore, the farther the lower liquid channel 40 is from the atomizer core 21, the greater the distance between the lower liquid point of the lower liquid channel 40 and the atomizer core 21, thus also extending the distance between the atomized substrate and the atomizer core 21.

[0053] Optionally, the atomizer core 21 includes a heating element 211 , a protective cover 213 , and a liquid guide 212 surrounding the heating element 211 .

[0054] The sheathing member 213 is provided with a liquid inlet hole 2131 , and the sheathing member 213 is sheathed outside the liquid guiding member 212 to separate the liquid guiding member 212 and the buffer member 22 . The buffer member 22 transfers liquid to the liquid guiding member 212 through the liquid inlet hole 2131 . The liquid guiding efficiency of the buffer member 22 is lower than that of the liquid guiding member 212 .

[0055] The heating element 211 is a heating wire.

[0056] The atomizer core 21 only includes a heating element 211 and a liquid guiding element 212 surrounding the heating element 211. The liquid guiding element 212 can be made of cotton, foam or other permeable materials. It should be noted that the material selection of the liquid guiding element 212 and the buffer element 22 must be such that the liquid guiding efficiency of the buffer element 22 is lower than that of the liquid guiding element 212. In this way, the buffer element 22 with low liquid guiding efficiency can slowly transfer the atomized matrix in the liquid storage chamber 111 to the liquid guiding element 212, avoiding excess atomized matrix on the liquid guiding element 212. At the same time, the liquid guiding element 212 with high liquid guiding efficiency can quickly absorb the atomized matrix stored in the buffer element 22, avoiding excess atomized matrix in the buffer element 22.

[0057] In addition to the above, the atomizer core 21 also includes a protective sleeve 213, which can be a metal tube. The sidewall of the protective sleeve 213 is provided with at least one liquid inlet hole 2131. The protective sleeve 213 isolates the buffer 22 and the liquid guide 212 to prevent direct contact between the two. Liquid can then be transferred between the buffer 22 and the liquid guide 212 only through the limited liquid inlet hole 2131, thereby achieving the purpose of controlling liquid flow efficiency. Furthermore, the aperture size of the liquid inlet hole 2131 can be adjusted according to the required liquid flow efficiency.

[0058] Optionally, the isolation member 23 includes a mounting seat 231, a first partition seal 232 and a second partition seal 233. On the side of the mounting seat 231 facing away from the liquid storage chamber 111, the second partition seal 233 is enclosed at the end of the mounting seat 231 to form a mounting chamber 2311 in the mounting seat 231. The first partition seal 232 is arranged on the side of the mounting seat 231 close to the liquid storage chamber 111, the atomizer core 21 and the buffer member 22 are arranged in the mounting chamber 2311, and the mounting seat 231 is located at the bottom wall of the mounting chamber 2311 at one end close to the liquid storage chamber 111, and a connecting hole 50 and at least one lower liquid channel 40 are provided. The connecting hole 20 connects the mounting chamber 2311 and the atomization channel 30, and the lower liquid channel 40 connects the mounting chamber 2311 and the liquid storage chamber 111.

[0059] The mounting seat 231 can be a columnar structure. A countersunk hole is provided at the bottom end of the mounting seat 231. The second partition seal 233 is enclosed at the bottom of the mounting seat 231, thereby forming a mounting cavity 2311 in the mounting seat 231. The mounting cavity 2311 opens downward, and the buffer member 22 mates with the mounting cavity 2311 and is disposed within the mounting cavity 2311. It can also be seen that the connecting hole 50 and the lower liquid channel 40 are both provided at the bottom of the mounting cavity 2311. The key point is that the connecting hole 50 and the lower liquid channel 40 extend through the bottom of the mounting cavity 2311. Similarly, the connecting hole 50 is also sleeved on the outer wall of the atomizing channel 30. The mounting seat 231 of this embodiment provides installation space for the atomizer core 21 and the buffer member 22. However, because the mounting cavity 2311 opens away from the liquid storage chamber 111, the atomizer core 21 is located within the isolation member 23 and is also located on the side of the isolation member 23 facing away from the liquid storage chamber 111. In addition, if the atomizer core 21 is completely located outside the isolation member 23 , the isolation member 23 is a sheet-like structure in which the mounting cavity 2311 is not provided.

[0060] Optional, combined Figure 5 and Figure 6 The first partition seal 232 includes a base ring 2321, and a first sealing ring 2322 arranged on the outside of the base ring 2321 and / or a second sealing ring 2323 arranged on the inside of the base ring 2321. The first sealing ring 2322 is arranged between the mounting seat 231 and the inner wall of the chamber 11, and the second sealing ring 2323 is sealed and arranged between the connecting hole 50 and the outer wall of the atomization channel 30.

[0061] The first partition seal 232 plays a sealing role, so the first partition seal 232 can be made of rubber or silicone.

[0062] It is understandable that the base ring 2321 can be selected as a ring structure.

[0063] First, combine Figure 5 The first isolation seal 232 includes a base ring 2321 and a first sealing ring 2322 disposed on the outer periphery of the base ring 2321. The base ring 2321 is mounted on top of the mounting seat 231. Note that the base ring 2321 does not block the lower liquid channel 40 and the connection hole 50. The first sealing ring 2322 is located between the mounting seat 231 and the inner wall of the chamber 11. The first sealing ring 2322 seals the gap between the mounting seat 231 and the inner wall of the chamber 11, preventing leakage.

[0064] Second, combine Figure 5Based on the first embodiment, the first partition seal 232 further includes a second sealing ring 2323 disposed on the inner ring of the base ring 2321. Similarly, the second sealing ring 2323 is disposed on the inner wall of the connecting hole 50. When the connecting hole 50 of the mounting base 231 is sleeved on the atomizing channel 30, the second sealing ring 2323 is used to seal the gap between the wall of the connecting hole 50 and the outer wall of the atomizing channel 30, similarly preventing leakage of the atomized matrix within the liquid storage chamber 111.

[0065] In addition, combined Figure 4 and Figure 5 In order to improve the reliability of the installation of the first partition seal 232 on the mounting seat 231, a plug-in block 80 is provided at the top of the connecting hole 50 of the mounting seat 231, and a plug-in groove 81 for plugging in the plug-in block 80 is provided at the bottom of the second sealing ring 2323. The plug-in block 80 is plugged into the plug-in groove 81, thereby completing the plug-in fit between the first partition seal 232 and the mounting seat 231.

[0066] Optional, combined Figure 8 The second partition seal 233 includes a peripheral sealing ring 2331 , a support ring 2332 and / or an insertion protrusion 2333 .

[0067] The peripheral sealing ring 2331 is sealingly disposed between the mounting seat 231 and the inner wall of the chamber 11 , and the peripheral sealing ring 2331 is located at one end of the mounting seat 231 away from the liquid storage chamber 111 .

[0068] The support ring 2332 is disposed on the inner side of the outer sealing ring 2331 , and the support ring 2332 is supported on an end of the buffer member 22 away from the liquid storage chamber 111 .

[0069] The insertion protrusion 2333 is disposed on the supporting ring 2332 , and the insertion protrusion 2333 is inserted into the buffer member 22 and abuts against an end of the atomizer core 21 away from the liquid storage chamber 111 .

[0070] The second partition seal 233 also plays a sealing role, so the second partition seal 233 can be made of rubber or silicone.

[0071] First, the first barrier seal 232 includes at least a peripheral sealing ring 2331, which is positioned between the mounting base 231 and the inner wall of the chamber 11. Similarly, the second barrier seal 233 also prevents leakage through this gap. Furthermore, the first sealing ring 2322 and the peripheral sealing ring each provide balanced support for the mounting base 231 at its upper and lower ends.

[0072] Secondly, based on the first embodiment, the second partition seal 233 also includes a support ring 2332. For example, the support ring 2332 is arranged at one end of the inner side of the outer sealing ring 2331. When the outer sealing ring 2331 is surrounded by the outer wall of the mounting seat 231, the support ring 2332 is supported on the lower end of the buffer 22 away from the liquid storage chamber 111 (that is, it is used to enclose below the countersunk hole to form the mounting chamber 2311). Thus, the support ring 2332 can support the buffer 22 so that it does not fall out of the mounting chamber 2311.

[0073] Third, based on the first and second embodiments of the present invention, the second partition seal 233 further includes an insertion protrusion 2333. In combination with the first and second embodiments of the present invention, the peripheral sealing ring 2331 is arranged on the outer ring of the support ring 2332, and the insertion protrusion 2333 is arranged on the inner ring of the support ring 2332. In this way, when the peripheral sealing ring 2331 surrounds the outer wall of the mounting seat 231, the support ring 2332 is supported on the lower end of the buffer 22 away from the liquid storage chamber 111, and at the same time, the insertion protrusion 2333 is inserted into the buffer 22 and abuts against the atomizer core 21. In more detail, the insertion protrusion 2333 abuts against the atomizer cotton of the atomizer core 21, so that the insertion protrusion 2333 can support the atomizer core 21 from the bottom.

[0074] In the above description, the first partition seal 232 and the first partition seal 232 are first installed on the mounting seat 231 and then installed together into the chamber 11 .

[0075] In addition, compression protrusions may be provided on the inner and outer side walls of the first sealing ring 2322 , the second sealing ring 2323 and the outer sealing ring 2331 , and the compression protrusions are used to form an extrusion seal with the nearest wall surface.

[0076] Optional, combined Figure 2 and Figure 6 The inner diameter of the lower liquid channel 40 gradually increases from the end close to the liquid storage chamber 111 to the end away from the liquid storage chamber 111.

[0077] Alternatively, tightening holes 41 are respectively provided at both ends of the lower liquid channel 40 , and the diameter of the tightening holes 41 gradually decreases from the outside to the inside.

[0078] The radius of the lower liquid channel 40 gradually increases from top to bottom, which can be understood as the lower liquid channel 40 being a trumpet-shaped hole in the opposite direction of the flow of the atomized matrix. The reverse trumpet hole usually increases the resistance to the flow of the atomized matrix (especially liquid), which may reduce the flow speed, minimize the speed of liquid outflow and the spray effect, and thus effectively control the flow rate or prevent the liquid from flowing out of the lower liquid channel 40 too quickly, so as to achieve more uniform and controlled penetration of the atomized matrix into the buffer 22.

[0079] In addition, combined Figure 7The two tightening holes 41 at both ends of the lower liquid channel 40 are two trumpet holes, the large diameter end of the upper trumpet hole serves as the liquid inlet end, and the large diameter end of the lower trumpet hole serves as the liquid outlet end (that is, the two tightening holes 41 located at both ends of the lower liquid channel 40 are in the direction from the outer end of the lower liquid channel 40 to the midpoint of the lower liquid channel 40, and the diameters of the two tightening holes 41 gradually decrease). The small diameter ends of the two trumpet holes can be connected or connected through a straight hole. The function of the two trumpet holes is that the upper one can be used to centrally introduce liquid, and the lower one can be used to control the flow rate.

[0080] Optionally, there are multiple lower liquid channels 40 , and the multiple lower liquid channels 40 are evenly arranged along the circumference of the isolation member 23 .

[0081] Among them, combined Figure 6 The number of liquid discharge channels 40 is at least two. The liquid discharge channels 40 can be conventional through holes or can be the trumpet-shaped ones mentioned above. The key point is that, taking two liquid discharge channels 40 as an example, the reason for designing two liquid discharge channels 40 is that during the use of the atomizer, the discharge of the atomized matrix in the liquid storage chamber 111 and the return of air are carried out simultaneously. If only one liquid discharge channel 40 is opened, the discharge and return of air will be carried out simultaneously in the same liquid discharge channel 40, which will lead to the phenomenon of bubble jamming. The poor return of air caused by the bubble jam affects the discharge of liquid and ultimately affects the atomization. Therefore, the two liquid discharge channels 40 can ensure that the discharge of liquid and the return of air are carried out simultaneously, reducing the probability of bubble jamming.

[0082] It is understandable that there may be three or more lower liquid channels 40 ; the plurality of lower liquid channels 40 may be evenly or symmetrically spaced along the circumference of the connecting hole 50 .

[0083] Optional, see Figure 1 The chamber 11 is formed with a liquid collecting chamber 112 below the atomizing core 21 .

[0084] The atomizing device further includes a liquid absorbing assembly 60 , which includes a first liquid absorbing member 61 . The first liquid absorbing member 61 is disposed in the liquid collecting chamber 112 . In the axial direction of the atomizing device, the projection of the atomizing core 21 covers the projection of the first liquid absorbing member 61 .

[0085] It can be understood from the above that the atomizer assembly 20 is installed from the bottom of the housing 10 , and therefore the liquid collecting chamber 112 is not used to collect the leaked liquid dripping from the atomizer assembly 20 .

[0086] For example, the first absorbent member 61 may be absorbent cotton or foam. In the axial direction of the atomizer device, the projection of the atomizer core overlaps the projection of the first absorbent member 61. This means that the first absorbent member 61 below the atomizer core 21 can absorb dripping liquid. In this embodiment, the first absorbent member 61 can be bonded to the inner wall of the liquid collection chamber 112.

[0087] Alternatively, after the atomizer assembly 20 is installed, an oil collecting cup may be installed in the liquid collecting chamber 112 to replace the liquid suction assembly 60 , and the dripping liquid may fall into the oil collecting cup. The oil collecting cup may be fixed in the liquid collecting chamber 112 of the housing 10 by snap-fitting.

[0088] Optionally, the liquid absorbing assembly 60 further includes a second liquid absorbing member 62 . The second liquid absorbing member 62 is disposed in the liquid collecting chamber 112 and connected to the first liquid absorbing member 61 .

[0089] The second liquid absorbing member 62 is disposed in the liquid collecting chamber 112 and connected to the first liquid absorbing member 61 .

[0090] Similarly, the second absorbent member 62 can be absorbent cotton or absorbent foam, and the first absorbent member 61 can be bonded to the inner wall of the liquid collection chamber 112. Importantly, the second absorbent member 62 abuts against the first absorbent member 61 and can be used to absorb liquid from the first absorbent member 61, thereby increasing the overall oil collection capacity. In addition, the second absorbent member 62 and the first absorbent member 61 are arranged separately to accommodate the space within the liquid collection chamber 112. The separate arrangement can effectively position the second absorbent member 62 and the first absorbent member 61 according to their spatial position within the liquid collection chamber 112 without bending or squeezing the two, thereby ensuring the liquid storage capacity of the second absorbent member 62 and the first absorbent member 61.

[0094] The battery assembly 70 includes a battery body 71 and a circuit board 72. The battery body 71 is connected to the circuit board 72, and the circuit board 72 has two external output pins. The heating element of the above-mentioned atomization device has two corresponding external input pins, and one output pin is connected to one input pin, thereby realizing the heating and atomization of the heating element.

[0095] In addition, the battery assembly 70 also includes a bottom cover 73, in which the battery body 71 and the circuit board 72 are both arranged. The bottom cover 73 is detachably connected to the lower end of the shell 10. At this time, the output pin and the input pin are connected using the existing abutment connection method; in addition, it can be known that the external switch button on the circuit board is used to control the power on and off of the heating element.

[0096] It should be noted that an air inlet is provided on the bottom cover 73 or the lower end of the shell 10 so that external air can enter the shell 10. This is a prior art and will not be described again here.
