Referring to fig. 1-6, a schematic diagram of an electronic atomizer according to a preferred embodiment of the present invention is shown. Atomizing device, including casing 1, atomizing core subassembly 2 and sealing member 3, casing 1 be equipped with oil storage chamber 14 and respectively with inlet port 111 and venthole 121 that oil storage chamber 14 is linked together, atomizing core subassembly 2 install in the oil storage chamber 14, and one end with inlet port 111 meets, and the other end stretches into venthole 121, in order to form and run through the atomizing passageway 26 of oil storage chamber 14. The atomizing core assembly 2 is provided with an oil guide hole 25 which is communicated with the atomizing channel 26 and the oil storage cavity 14. One end of the sealing element 3 penetrates through the air outlet hole 121 and covers the atomizing core assembly 2 to seal the oil guide hole 25, and the other end of the sealing element 3 extends out of the oil storage cavity 14 from the air outlet hole 121. When the part of the sealing member 3 extending out of the oil storage chamber 14 is pulled, the sealing member 3 moves relative to the atomizing core assembly 2 and opens the oil guide hole 25, so that the atomizing passage 26 is communicated with the oil storage chamber 14. In the embodiment, the seal member 3 covers the atomizing core assembly 2 movably to seal the oil guide hole 25, so that the atomizing passage 26 and the oil storage chamber 14 are isolated, and oil in the oil storage chamber 14 cannot enter the atomizing passage 26. When a user needs to use the electronic atomization device, the oil guide hole 25 can be opened by pulling the sealing piece 3 to conduct the atomization passage 26 and the oil storage chamber 14, and the structure can effectively prevent oil from seeping out of the atomization passage 26 before use or in transportation.
In the present embodiment, as shown in fig. 2 and fig. 4 to 6, the housing 1 includes a cover 11 and a base 12, the cover 11 is provided with a mounting groove (not shown) and an air outlet 121, and the air outlet 121 is opposite to an opening end of the mounting groove. In practical application, an end of the cover body 11 opposite to the opening end is convexly provided with an air column 112, and the air column 112 extends into the mounting groove and is provided with a through air outlet 121 along the axial direction. Thus, the inner wall side of the vent column 112 forms the hole wall of the air outlet hole 121, so that the contact area between the atomizing core assembly 2 and the sealing element 3 and the hole wall of the air outlet hole 121 can be increased, and the structural stability and the joint strength are enhanced. The base 12 is provided with an air inlet hole 111, and the base 12 is installed at the open end of the installation groove and closes the open end, so that the base 12 and the cover 11 enclose an oil storage chamber 14. Wherein, the air outlet hole 121 and the air inlet hole 111 are both communicated with the oil storage cavity 14. In practical application, the periphery of base 12 has cup jointed the silica gel circle, when base 12 install in during the open end, the silica gel circle respectively with the periphery of base 12 and the inner wall elasticity butt of mounting groove to the gap between sealing base 12 and the casing 1 prevents that the fluid of filling in oil storage chamber 14 from flowing out from the clearance between base 12 and the casing 1. Furthermore, a decoration 13 adapted to the base 12 may be covered on a side of the base 12 exposed outside the oil storage cavity 14, and the decoration 13 is fastened to the periphery of the housing 1 by interference, or fastened to the periphery of the housing 1 by a buckle, so as to protect the base 12 and further prevent the base 12 from coming off the housing 1.
In the present embodiment, referring to fig. 2, the atomizing core assembly 2 includes a heating element 21, an oil guiding element (not shown), a sleeve 22, a sealing ring 24, and a casing 23. The heating element 21 is a hollow columnar structure formed by winding a heating wire, and has a first through hole penetrating in an axial direction. The oil guide member is sleeved on the periphery of the heating member 21, the oil guide member can be made of oil guide cotton or porous ceramic material, and can be connected with the heating member 21 in a split manner or integrally formed. The sleeve 22 is sleeved on the periphery of the oil guide to provide protection and support. One end of the sleeve 22 extends along the direction far away from the heating element 21 to form a boss seat, and the diameter of the boss seat is larger than that of the sleeve 23. The seal ring 24 is a stepped seal ring 24 adapted to the boss base, and is accommodated in the boss base and elastically abuts against an inner wall of the boss base. The jacket 23 covers the sleeve 22 from the other end of the sleeve 22, and is in interference fit with the outer periphery of the boss base to be fastened to the sleeve 22. One end of the jacket 23, which is far away from the heat generating element 21, extends into the air outlet hole 121 to form an air duct 231 communicated with the air outlet hole 121 and the first through hole respectively.
Correspondingly, the base 12 is provided with an annular accommodating groove 122 for installing the atomizing core assembly 2, and the annular accommodating groove 122 surrounds the air inlet holes 111. One end of the atomizing core assembly 2 is accommodated in the annular accommodating groove 122 and is in interference fit with the side wall of the annular accommodating groove 122 so as to be fastened on the base 12, and the air inlet 111, the first through hole, the air duct 231 and the air outlet 121 are sequentially communicated to form the atomizing channel 26. Further, the lateral wall of inlet port 111 is convexly located in annular holding tank 122, make sealing washer 24 cup joint in the lateral wall of inlet port 111 prevents that atomizing core subassembly 2 from taking place radial displacement and causing some or whole jam inlet port 111. Further, the bottom wall of the annular accommodating groove 122 is provided with at least one air vent, and the at least one air vent is communicated to the outside air. When the packing 24 is mounted in the annular receiving groove 122, the packing 24 completely fills the annular receiving groove 122 and exhausts the air in the annular receiving groove 122 through the at least one exhaust hole.
Since the diameter of the boss seat is larger than the diameter of the jacket 23, an annular gap exists between the jacket 23 and the outer periphery of the sleeve 22. In order to improve the oil guiding efficiency and prevent oil from accumulating in the gap between the casing 23 and the sleeve 22, the annular gap between the casing 23 and the sleeve 22 may be filled with an oil guiding member to absorb the oil. Correspondingly, the side walls of the sleeve 22 and the jacket 23 are respectively provided with a second through hole 221 and a third through hole 232, and the second through hole 221 and the third through hole 232 are coaxial to form an oil guide hole 25 communicating the oil storage chamber 14 and the atomizing channel 26. Thus, the oil in the oil storage chamber 14 can only enter the atomizing channel 26 through the oil guide hole 25, and then is absorbed by the oil guide member and atomized into aerosol by the heat generating member 21.
In the present embodiment, as shown in fig. 3, the sealing member 3 is made of a soft rubber material, such as silicon rubber, silicon rubber or rubber, which utilizes its compactness, softness and elasticity to achieve sealing. The seal 3 comprises a sleeve part 31 and a pull rod part 32. The pull rod portion 32 is connected to one end of the sleeve portion 31 and extends out of the reservoir chamber 14 for user operation. The sleeve part 31 is provided with a mounting hole 311 matched with the atomizing core assembly 2 along the axial direction at one end far away from the pull rod part 32. I.e. the shape and size of the mounting hole 311 is adapted to the shape and size of the jacket 23. One end of the sleeve part 31 extending into the air outlet 121 from the air duct 231 covers the atomizing core assembly 2 and closes the third through hole 232. That is, the portion of the jacket 23 extending from the third through hole 232 to the air outlet 121 is accommodated in the mounting hole 311, and the third through hole 232 is covered by the wall of the mounting hole 311. Preferably, the mounting hole 311 is in interference fit with the jacket 23, that is, a hole wall of the mounting hole 311 is elastically abutted to an outer surface of the jacket 23. Thus, the oil in the oil storage chamber 14 cannot pass through the gap between the jacket 23 and the mounting hole 311, and then enters the oil guide hole 25 through the third through hole 232, so that the oil guide hole 25 is completely closed by the seal member 3. This prevents oil in the oil reservoir chamber 14 from entering the atomization passage 26 through the oil guide hole 25 during transportation or before use by a user, and leaking out of the electronic atomization device through the atomization passage 26. On the other hand, the contact between the oil and the outside air can be completely isolated, the oil is effectively prevented from being discolored or deteriorated due to oxidation reaction, and the service life of the oil is prolonged.
As shown in fig. 4-5, since the air duct 231 extends into the air outlet 121, the sleeve portion 31 is partially received in the air outlet 121, is located between the outer periphery of the air duct 231 and the inner wall of the air outlet 121, and is elastically abutted against the inner wall of the air outlet 121 and the outer periphery of the air duct 231, so as to fill the gap between the air outlet 121 and the air duct 231, and prevent the oil in the oil storage chamber 14 from flowing out from the gap between the air outlet 121 and the air duct 231. In practical applications, the length of the sleeve portion 31 received in the air outlet 121 may be adapted to the length of the air duct 231 extending into the air outlet 121. The length of the sleeve part 31 accommodated in the air outlet pipe can be longer than the length of the air guide pipe 231 extending into the air outlet hole 121 or extending out of the oil storage cavity 14 from the air outlet hole 121.
In this embodiment, the mounting hole 311 may be a through hole penetrating the sealing member 3, that is, the mounting hole 311 extends to the pull rod portion 32 and penetrates the pull rod portion 32. The mounting hole 311 may be a blind hole, that is, the pull rod 32 is a solid rod structure, which is connected to the sleeve portion 31 and closes one end of the mounting hole 311, so that the mounting hole 311 is a blind hole. Preferably, the pull rod portion 32 is a solid rod structure, so that the portion of the pull rod portion 32 extending out of the oil reservoir 14 can withstand greater tensile forces, preventing damage during the tensile process. On the other hand, the pull rod part 32 closes the mounting hole 311 to form a blind hole, and when the atomizing core assembly 2 is loaded into the mounting hole 311 from the open end of the blind hole, the atomizing core assembly 2 can be positioned by using the end surface of the pull rod part 32 (the closed end of the blind hole). When the end surface of the air duct 231 abuts against the end surface of the pull rod portion 32 (the closed end of the blind hole), the atomizing core assembly 2 is mounted in place. The blind end of blind hole can also restrict atomizing core subassembly 2 at axial direction's displacement for atomizing core subassembly 2 centre gripping is favorable to keeping the stability of atomizing core subassembly 2 position between this blind end and base 12 on axial direction.
Further, as shown in fig. 4, at least one third protruding ring 321 is circumferentially disposed on the outer periphery of the pull rod portion 32, and the at least one third protruding ring 321 is located outside the oil storage chamber 14. This increases the roughness of the surface of the pull rod portion 32, and facilitates the user's exertion. In practical applications, a groove, a rib, a bump, a hob line or other structures may be further disposed on the outer circumferential surface of the pull rod portion 32 to increase the surface roughness of the pull rod portion 32, or the outer shape of the pull rod portion 32 is set to a shape convenient for a user to hold, so as to facilitate the application of force by the user. When the pull rod portion 32 is pulled, the pull rod portion 32 drives the sleeve portion 31 to move relative to the atomizing core assembly 2 and the housing 1, and gradually opens the oil guide hole 25, so that the oil storage chamber 14 and the atomizing passage 26 are communicated through the oil guide hole 25, and therefore oil in the oil storage chamber 14 can enter the atomizing passage 26 through the oil guide hole 25, and is absorbed by the oil guide member, and then is atomized into aerosol by the heat generating member 21.
As shown in fig. 4 to 6, since the sleeve portion 31 not only functions to close/open the oil guide hole 25 but also serves to fill the gap between the air outlet hole 121 and the atomizing core assembly 2, the seal member 3 cannot be completely pulled out of the housing 1 when the pull rod portion 32 is pulled, and it is necessary to keep a part of the seal member 3 sandwiched between the air guide hole and the atomizing core assembly 2. Preferably, the sealing member 3 covers the outer periphery of one end of the atomizing core assembly 2 (i.e. the outer periphery of the sleeve portion 31), and is sequentially provided with at least one first convex ring 312, a breaking portion 313, at least one second convex ring 314 and a limiting boss 315 along the axial direction. The outer diameter of the limiting boss 315 is larger than the aperture of the air outlet 121. Therefore, the limiting boss 315 cannot extend into the air outlet hole 121 in the moving process of the sealing element 3, but abuts against the end surface of the air outlet hole 121 (i.e., the end surface of the vent column 112 extending into the oil storage chamber 14) to limit the sealing element 3. When the sealing member 3 is in a state of closing the oil guiding hole 25, the at least one first convex ring 312 is clamped between the air outlet hole 121 and the atomizing core assembly 2 (i.e. the air guiding pipe 231) to fill a gap between the air outlet hole 121 and the atomizing core assembly 2. When the sealing element 3 is pulled and moves relative to the atomizing core assembly 2 to the position-limiting boss 315 to abut against the end surface of the air outlet hole 121, the sealing element 3 is separated from the oil guide hole 25, so that the oil guide hole 25 is opened, and the at least one second flange 314 is clamped between the air outlet hole 121 and the atomizing core assembly 2 to fill the gap between the air outlet hole 121 and the atomizing core assembly 2, and simultaneously, the sealing element 3 is disconnected from the disconnection portion 313. Namely, the broken part 313 side, namely, the part including the first convex ring 312 and the pull rod part 32 is separated from the sealing member 3; the other side of the break 313, i.e., the portion including the second bead 314 and the retaining boss 315, continues to remain in the reserve chamber 14.
In this embodiment, the first convex ring 312 and the second convex ring 314 are additionally arranged on the periphery of the sealing element 3, so that the sealing element 3 forms spaced surface contact with the at least one first convex ring 312 and the at least one second convex ring 314 respectively in two positions, thereby not only increasing the acting force between the sealing element 3 and the air outlet 121 and improving the sealing performance, but also reducing the actual contact area between the sealing element 3 and the air outlet 121, and being beneficial to reducing the pulling resistance. In practical application, the number and the diameter of the two convex rings can be set according to practical situations.
The breaking portion 313 is a recessed portion disposed along the circumferential direction of the sealing member 3, and the thickness of the recessed portion is smaller than the thickness of other portions of the sealing member 3, so that the thickness of the recessed portion is the smallest and most easily broken when the sealing member 3 is under tension. Preferably, the breaking part 313 is a triangular slot with a sharp corner pointing towards the center, which can generate stress concentration around the circumference formed by the sharp corner when the sealing member 3 is under tension, so that the sealing member 3 is more easily broken from the breaking part 313. The breaking part 313 is arranged, so that after a user pulls the sealing piece 3 to open the oil guide hole 25, the sealing piece 3 is directly broken from the breaking part 313, the sealing function is continuously realized, and the operation is simple. It should be noted that, in practical applications, the length of the sleeve portion 31 may be increased appropriately, so that when the sealing member 3 moves to open the oil guide hole 25, the sleeve portion 31 at least partially protrudes from the air outlet hole 121 out of the oil storage chamber 14. Thus, even if there is no break portion 313 or the break portion 313 fails to break, the user can open the air outlet 121 by shearing the sleeve portion 31, and thus the electronic atomizing device can be normally used.
The invention also provides an aerosol generator which comprises a power supply device and an electronic atomization device, wherein the power supply device is detachably connected with the electronic atomization device to provide power for the electronic atomization device. The specific structure of the electronic atomization device refers to the above embodiments, and since the aerosol generator adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
