DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Technical solutions in the embodiments of the present application will be described clearly and thoroughly hereinafter with reference to the accompanying drawings. Apparently, the embodiments described herein are merely parts of but not exclusive embodiments of the present application. All alternative embodiments obtained by those skilled in the art based on the embodiments of the present application without creative works shall fall within the protection scope of the present application.

The First Embodiment

Referring to FIG. 1, an atomizer includes a housing assembly 10, an isolating assembly 20 and an atomizing assembly 30. The isolating assembly 20 is positioned within the housing assembly 10, and an air intake passage 22 is formed between the isolating assembly 20 and the housing assembly 10. The atomizing assembly 30 is positioned within the isolating assembly 20, and a liquid storage chamber 23 is formed between the atomizing assembly 30 and the isolating assembly 20. Therefore, the isolating assembly 20 can effectively isolate the air intake passage 22 from the liquid storage chamber 23, to avoid an interference between the air intake passage and the liquid storage chamber, thereby improving an operational reliability of the electronic cigarette.

Specifically, the housing assembly 10 includes an upper cover 17, a first external sleeve 241, and a bottom cover 245. The upper cover 17 and the bottom cover 245 are positioned on the upper end and the lower end of the first external sleeve 241, respectively. As shown in FIG. 1, the first external sleeve 241 defines an air intake hole 11 at an upper end of the first external sleeve 241, the air intake hole 11 fluidly communicates with the air intake passage 22, for air intake. Because the air intake hole 11 is positioned on the upper end of the first external sleeve 241, thus, even when the liquid in the liquid storage chamber 23 is leaked into the air intake passage 22 by gravity, the liquid gathers in the bottom cover 245, and does not leak out from the air intake hole 11. The bottom cover 245 is provided with an assembly protrusion 359 at an upper end of the bottom cover 245, the assembly protrusion 359 protrudes upwardly along an axial direction of the atomizer.

It should be noted that, the bottom cover 245 can be detachably assembled. If the atomizer breaks down, when the bottom cover 245 gathers a predetermined amount of leaked liquid, user can disassemble the bottom cover 245 to clear the liquid.

Alternatively, the housing assembly 10 further includes a mouth piece 18 positioned on an upper end of the upper cover 17. The mouth piece 18 can also be omitted. User can directly suck on the protrusion of the upper cover 17.

In the illustrated embodiment as shown in FIG. 1, the isolating assembly 20 includes a first internal sleeve 247 within the first external sleeve 241, the air intake passage 22 is formed between the first internal sleeve 247 and the first external sleeve 241, such that, airflow enters the atomizer via the air intake hole 11, and flows into the atomizing assembly 30 via the air intake passage 22.

In the illustrated embodiment as shown in FIG. 1, the atomizing assembly 30 includes an atomizing sleeve 31 and an atomizing head 35. The atomizing sleeve 31 is a hollow structure having two openings at opposite ends, and substantially has a trumpet shape. The atomizing sleeve 31 is positioned within the first internal sleeve 247, the upper end of the first internal sleeve 247 resists the upper cover 17, the lower end of the first internal sleeve 247 resists the lower end of the atomizing sleeve 31, (specifically, the lower end of the first internal sleeve 247 resists a trumpet opening of the lower end of the atomizing sleeve, the trumpet opening opens outwardly). Therefore, the atomizing sleeve 31, the first internal sleeve 247 and the upper cover 17 forms the liquid storage chamber 23 cooperatively. In order to improve an air-tightness between the atomizing sleeve 31 and the first internal sleeve 247, a sealing member (not shown) is positioned between the atomizing sleeve 31 and the first internal sleeve 247. The upper end of the atomizing sleeve 31 is connected to the upper cover 17. The lower end of the atomizing sleeve 31 is connected to the circumferential surface of the assembly protrusion 359. The atomizing sleeve 31 forms an atomizing chamber 244 in the inner chamber of the atomizing sleeve 31. The atomizing chamber 244 fluidly communicates with the mouth piece 18. The atomizing head 35 is positioned in the atomizing chamber 244, and the lower end of the atomizing head 35 is connected to the internal circumferential surface of the assembly protrusion 359. The smog generated by the liquid which is atomized by the atomizing head 35 can flow out via the atomizing chamber 244, and the mouth piece 18, for user to suck on.

The atomizing head 35 includes a supporting pipe 351, a liquid guiding member 352, a heater 353, and an electrode contacting member 354 electrically connected to the heater 353. When the supporting pipe 351 is assembled in the atomizing sleeve 31, the lower end of the supporting pipe 351 is connected to the internal circumferential surface of the assembly protrusion 359. The liquid guiding member 352 is sleeved on the heater 353, the supporting pipe 351 is sleeved on the liquid guiding member 352, the internal circumferential surface of the liquid guiding member 352 abuts the heater 353, the circumferential surface of the liquid guiding member 352 abuts the supporting pipe 351. The atomizing sleeve 31 defines a liquid intake hole 311, the supporting pipe 351 defines a liquid passing hole 355, thus the liquid in the liquid storage chamber 23 flows to the liquid guiding member 352 via the liquid intake hole 311 and the liquid passing hole 355. The heater 353 can be driven by the electric to heat up the liquid in the liquid storage chamber 23 to form the smog. The electrode contacting member 354 is positioned on the lower end of the supporting pipe 351, the electrode contacting member 354 passes through the assembly protrusion 359 and extends into the bottom cover 245. An insulating member (not labeled) is positioned between the electrode contacting member 354 and the supporting pipe 351. The electrode contacting member 354 defines a ventilation hole 356 fluidly communicating with the atomizing chamber 244. The bottom cover 245 defines a ventilation groove 243 which fluidly communicates with the air intake passage 22 and the ventilation hole 356. Outside airflow flows into the atomizing chamber 244 via the air intake hole 11, the air intake passage 22, the ventilation groove 243 and the ventilation hole 356. The airflow is mixed with the smog and flows out from the mouth piece 18 for user to suck on. Because the outside airflow flows into the atomizer via the lower end of the atomizing chamber 244 and flows out from the upper end of atomizing chamber 244, the airflow flows through the whole atomizing head 35; thus, the outside airflow can completely carries the smog generated from the liquid which is atomized by the atomizing head 35, the flavor is improved, a waste of the smog is avoided. Thus, the following situation can be avoided: when the smog cannot be carried out completely, the residual smog is condensed to form liquid after the electronic cigarette is disused, and causes the atomizing chamber 244 to produce liquid accumulation. Further, even if the liquid accumulation is formed, user can disassemble the bottom cover 245 to clear the liquid.

The Second Embodiment

The second embodiment provides another atomizer, the specific structure is illustrated as follows:

Referring to FIG. 2 through FIG. 6, the atomizer includes a housing assembly 10, an isolating assembly 20 and an atomizing assembly 30. The isolating assembly 20 is positioned in the housing assembly 10, and an air intake passage 22 is formed between the isolating assembly 20 and the housing assembly 10. The atomizing assembly 30 is positioned in the isolating assembly 20, and a liquid storage chamber 23 is formed between the atomizing assembly 30 and the isolating assembly 20. Therefore, the isolating assembly 20 can effectively isolate the air intake passage 22 from the liquid storage chamber 23, to avoid an interference between the air intake passage and the liquid storage chamber, thereby improving an operational reliability of the electronic cigarette.

The difference between the first embodiment and the second embodiment is that, in the second embodiment, beside the upper cover 17, the first external sleeve 241, and the bottom cover 245, the housing assembly 10 further includes a second external sleeve 27. Besides the first internal sleeve 247, the isolating assembly 20 further includes a second internal sleeve 26. Besides the atomizing sleeve 31 and the atomizing head 35, the atomizing assembly 30 further includes a ventilation pipe 25. An additional air intake passage 221 is formed between the second internal sleeve 26 and the second external sleeve 27. An additional liquid storage chamber 211 is formed between the second internal sleeve 26 and the ventilation pipe 25. The second internal sleeve 26 is positioned on the upper end of the first internal sleeve 247, the second external sleeve 27 is positioned on the upper end of the first external sleeve 241, the ventilation pipe 25 is positioned on the upper end of the atomizing sleeve 31, thereby causing the additional air intake passage 221 to fluidly communicate with the air intake passage 22, causing the additional liquid storage chamber 211 to fluidly communicate with the liquid storage chamber 23, The lumen of the ventilation pipe 25 fluidly communicates with the atomizing chamber 244. Therefore, when user expect to increase the liquid storage volume, the second internal sleeve 26 and the ventilation pipe 25 can be assembled, thereby the additional liquid storage chamber 211 can be obtained. At the time, the user can further assembly the second external sleeve 27 for improve an integrality of the appearance of the atomizer.

Referring to FIG. 12 and FIG. 13, the first internal sleeve 247 is provided with a plurality of protruding flanges 248 at an external surface of the first internal sleeve 247. The protruding flange 248 extends along an axial direction of the first internal sleeve 247. The number of the plurality of protruding flanges 248 is at least two, the plurality of protruding flanges 248 are uniformly disturbed on the circumferential surface of the first internal sleeve 247. The plurality of protruding flanges 24 are spaced from each other. Every two adjacent protruding flanges 248 forms a ventilation recess 249 there-between, the air intake passage 22 is formed between the ventilation recess 249 and the first external sleeve 241. The protruding flange 248 tightly engages the first external sleeve 241 for fixing the first internal sleeve 247. The upper end of the first internal sleeve 247 is provided with a dome 246, the external circumference of the dome 246 is provided an assembly groove 2462, the assembly groove 2462 is arranged along the circumferential direction of the first internal sleeve 247. The center of the dome 246 defines an assembly hole 2461 and a liquid passing groove 2463, the liquid passing groove 2463 is positioned between the assembly groove 2462 and the assembly hole 2461. The second internal sleeve 26 extends into the assembly groove 2462. Alternatively, when the first internal sleeve 247 is processed, the protruding flange 248 can be formed on the first internal sleeve 247 by injection molding or stamping.

Referring to FIG. 5 and FIG. 6, the atomizing sleeve 31 has a substantially convex shape. The upper end of the atomizing sleeve 31 extends into the assembly hole 2461, the ventilation pipe 25 extends into the upper end of the atomizing sleeve 31, for the lumen of the ventilation pipe 25 to fluidly communicate with the atomizing chamber 244. The atomizing head 35 is positioned in the atomizing chamber 244, and specifically positioned on the lower end of the atomizing sleeve 31. The liquid storage chamber 23 and the additional liquid storage chamber 211 are communicated with each other via the liquid passing groove 2463, causing the liquid in the additional liquid storage chamber 211 to flow into the liquid storage chamber 23 via the liquid passing groove 2463, thereby accomplishing a replenishment for the liquid storage chamber 23. In the illustrated embodiment, in order to facilitate for user to observe the liquid volume in the additional liquid storage chamber 211, in order to timely supply the liquid, the second internal sleeve 26 and the second external sleeve 27 are made of transparent or translucent materials, for example, the material is glass. Accordingly, in the first embodiment, the first internal sleeve 241 and the first internal sleeve 247 are made of transparent or translucent materials, facilitating for user to observe the liquid in the liquid storage chamber 23.

The difference between the first embodiment and the second embodiment is further that, in the second embodiment, the atomizing head 35 has a structure different from that in the first embodiment. As shown in FIG. 7 through FIG. 11, the atomizing head 35 includes an assembly seat 357, a liquid guiding member 352 and a heater 353. The assembly seat 357 is provided with an assembly post 358 protruding upwardly from an upper end of the assembly seat 357 along an axial direction of the assembly seat 357. The heater 353 is wound about the liquid guiding member 352, and opposite ends of the heater 353 are fixed to the assembly post 358.

Because the structure of the atomizing head 35 is different from that in the first embodiment, therefore, the matching mode between the atomizing head 35 and the first internal sleeve 347, the atomizing sleeve 31 and the bottom cover 245 is different from that in the first embodiment.

Specifically, the assembly seat 357 includes a first isolating plate 333 and a second isolating plate 332. Both the first isolating plate 333 and the second isolating plate 332 extend outwardly along a radial direction of the assembly seat 357. The first isolating plate 333 is positioned above the second isolating plate 332. The first isolating plate 333 has an external diameter less than that of the second isolating plate 332. The lower end of the atomizing sleeve 31 tightly engages the circumferential surface of the first isolating plate 333. The lower end of the first internal sleeve 247 tightly engages the circumferential surface of the first isolating plate 333. The upper end of the assembly seat 357 defines a liquid intake groove 32 fluidly communicating with a gap 334 between the first isolating plate 333 and the second isolating plate 332. Opposite ends of the liquid guiding member 352 are latched in the liquid intake groove 32. Therefore, the liquid in the liquid storage chamber 23 flows into the gap 334 between the first isolating plate 333 and the second isolating plate 332, and can be absorbed by the liquid guiding member 352 which is clamped by the liquid intake groove 32. The assembly seat 357 further defines an air passing hole 34 extending along an axial direction of the assembly seat 357, the air passing hole 34 cuts through opposite ends of the assembly seat 357. The air passing hole 34 fluidly communicates with the atomizing chamber 244 and the air intake passage 22. The air passing hole 34 is isolated from the gap 334 between the first isolating plate 333 and the second isolating plate 332, for isolating the liquid storage chamber 23 from the air intake passage 22. The assembly seat 357 is provided with a connecting post 36 protruding from a lower end surface of the assembly seat 357. The connecting post 36 protrudes downwardly along an axial direction of the assembly seat 357. At least a part of the connecting post 36 extends out of the bottom cover 245, the part of the connecting post 36 extending out of the bottom cover 245 is provided with a plurality of external threads which is configured to engage the battery assembly.

Referring to FIG. 7 and FIG. 11, when the connecting post 36 engages the battery assembly via threads, in order to avoid a following rotation of the atomizing head 35 which influences the assembly procedure, the peripheral of the atomizing head 35 is provided with a first positioning member 331, accordingly, the first internal sleeve 247 is provided with a second positioning member 28 engaging the first positioning member 331, for limiting a circumferential direction rotation of the atomizing head 35. Specifically, the first positioning member 331 is a positioning cutout on the second isolating plate 332, the second positioning member 28 is a positioning protrusion on the first internal sleeve 247, the positioning protrusion latches in the positioning cutout, for limiting a relative rotation between the atomizing head 35 and the first internal sleeve 247.

In the atomizing head 35 in the illustrated embodiment, user can replace the heater 353 and/or the liquid guiding member 352 by a self-reliance, and a dripping function can also be achieved, i.e. the liquid is not dripped into the liquid storage chamber 23 and the additional liquid storage chamber 211, on the contrary, the liquid is directly dripped on the liquid guiding member 352. When user want to achieve a liquid dripping function or replace the heater 353 of the atomizing assembly 30 or replace the liquid guiding member 352 of the atomizing assembly 30, merely the bottom cover 245 is rotated to open, thus the atomizing head 35 together with the bottom cover 245 can be taken down, therefore, a liquid dripping operation or an replacement operation can be performed, it is easy and convenient.

Not only that, the difference between the second embodiment and the first embodiment, in the second embodiment, the housing assembly 10 further includes a connecting member 13 and an adjusting member 14, the air intake hole 11 is positioned on the connecting member 13, the adjusting member 14 is rotatably positioned on the connecting member 13 to adjust an air intake volume of the air intake hole 11. By a control of a relative position between the adjusting member 14 and the air intake hole 11, an effective air intake volume of the air intake hole 11 can be changed.

As shown in FIG. 4, the upper end of the second external sleeve 27 and the upper end of the second internal sleeve 26 extend into the lower end of the connecting member 13. The upper cover 17 covers the upper end of the connecting member 13. The connecting member 13 defines an air intake hole 11, for air intake. Therefore, air enters the atomizer by the air intake hole 11, and passes through the additional air intake passage 221, and flows into the air intake passage 22, and then the air enters into the atomizing chamber 244 via the air passing hole 34, the air is mixed with the smog, and flows out through the lumen of the ventilation pipe 25 and the upper cover 17.

In the illustrated embodiment as shown in FIG. 14, the connecting member 13 includes a bottom plate 131, an air outlet conduit 132, and a spacer bush 133, the air outlet conduit 132 and the spacer bush 133 are axially positioned on the bottom plate 131, and a spacer bush 133. The spacer bush 133 is positioned outside the air outlet conduit 132. The air outlet conduit 132 is sleeved on the ventilation pipe 25. The air intake hole 11 is positioned on a region of the bottom plate 131 outside the spacer bush 133. The bottom plate 131 defines a liquid injection hole 134 on a region between the spacer bush 133 and the air outlet conduit 132, the liquid injection hole 134 fluidly communicates with the additional liquid storage chamber 211. Therefore, the spacer bush 133 completely isolates the air intake hole 11 from the liquid injection hole 134, guaranteeing an independence of the liquid intake and the air intake.

In the specific embodiment as shown in FIG. 14 and FIG. 15, the regulating ring has a first limiting member 143, the connecting member 13 has a second limiting member 135 engaging the first limiting member 143, when the first limiting member 143 contacts a side of the second limiting member 135, the air passing cutout 141 is completely fluidly communicated with the air intake hole 11, when the first limiting member 143 contacts an opposite side of the second limiting member 135, the air passing cutout 141 is staggered from the air intake hole 11. By a configuration of the first limiting member 143 and the second limiting member 135, a rotatably relative position between the adjusting member 14 and the connecting member 13 can be effectively controlled, a reliable regulating of an air intake volume of the air intake hole 11 can be accomplished.

Specifically, the first limiting member 143 is a limiting protrusion on the regulating ring, the second limiting member 135 is a limiting slidable groove on the connecting member 13, the limiting protrusion is slidable in the limiting slidable groove. When the regulating ring is rotated to drive the limiting protrusion to contact a side of the limiting slidable groove, the air passing cutout 141 is aligned to the air intake hole 11, at the time, the air intake hole 11 is completely opened. When the regulating ring is rotated to drive the limiting protrusion to contact an opposite side of the limiting slidable groove, the air passing cutout 141 is staggered from the air intake hole 11, at the time, the air intake hole 11 is completely closed. The positions of the limiting protrusion and the limiting slidable groove can be exchanged, i.e. the first limiting member 143 is a limiting slidable groove, the second limiting member 135 is a limiting protrusion, a same limiting effect can be achieved.

Taking an air-tightness into consideration, the housing assembly 10 further includes a sealing ring 15, the sealing ring 15 is sleeved on the external side of the spacer bush 133 and is positioned above the regulating ring, allowing the air passed through the air passing cutout 141 to flow to the air intake hole 11, referring to FIG. 4.
