Detailed implementation manners

[0035] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] The present invention provides an electronic cigarette and its atomizing device. Among them, the structure of the electronic cigarette is as Figure 1 shown, including a mouthpiece 100, an atomizing device 200 and a power supply device (not shown in the figure). The mouthpiece 100 is covered on the upper end of the atomizing device 200, and a suction port 110 is opened on the mouthpiece 100; the atomizing device 200 is used to atomize the atomizing liquid for the user to inhale; the power supply device is used to provide power for the atomizing device 200.

[0039] The structure of the atomizing device 200 is as shown in Figures 2 - 4 shown. The atomizing device 200 includes a housing 300, an atomizing component 400, and a fixing seat 500. The atomizing component 400 includes a fixing bracket 410, a sleeve 420, and a liquid guiding member 430. As Figure 3 shown, a baffle 310 is provided inside the housing 300. The baffle 310 divides the space inside the housing 300 into an air outlet channel 311 and a liquid storage chamber 312. The central axis of the air outlet channel 311 is close to the inner wall of the housing 300, thus forming a side air outlet structure. The side air outlet structure solves the problem that the air outlet channel 311 directly leading to the suction port 110 is likely to allow the user to inhale liquefied liquid; the atomizing component 400 is located inside the housing 300 and includes a fixing bracket 410, a sleeve 420, and a liquid guiding member 430; the fixing seat 500 is hermetically provided at the lower end of the housing, and a heating element 431 is provided on the bottom surface of the liquid guiding member 430 close to the fixing seat 500. In a specific embodiment, the liquid guiding member 430 is a ceramic core, and the heating element 431 is a printed circuit. The printed circuit is printed on the bottom surface of the ceramic core close to the fixing seat 500. The printed circuit includes an iron-chromium-aluminum printed circuit or a nickel-chromium printed circuit. The printing production method of the printed circuit enables the width w of the liquid guiding member 430 to be very thin. As Figure 5 shown, it is convenient to be used in a flat atomizing device 200 and an electronic cigarette with a small specification size. For example, the width w of the liquid guiding member 430 can be less than or equal to 2.5 mm. It can be understood that in other specific embodiments, the liquid guiding member 430 can also be a cotton core, and the heating element 431 can also be a heating wire, and the heating wire can be wound around the cotton core.

[0040] In addition, as Figure 3 , Figure 4 and Figure 5As shown, the fixing base 500 is used to fix the atomization component 400 inside the housing 300. The fixing base 500 includes an integrally formed base 510 and a seat body 520. A locking buckle 521 is provided on the outer wall of the seat body 520, and a notch 320 is provided on the inner wall of the housing 300. The locking buckle 521 can cooperate with the notch 320 so that the seat body 520 is snap-connected inside the housing 300 and the fixing base 500 is closely attached to the lower end of the housing 300. The length and width dimensions of the base 510 are both larger than those of the seat body 520, and the length and width dimensions of the base 510 are larger than or equal to those of the housing 300. An air inlet hole 511 and an electrode hole 512 are provided on the base 510. The electrode hole 512 extends upward through the thickness of the seat body 520 and is used for the electrode 600 to be inserted. The electrode 600 is used for electrically connecting with the heating element 431 on the bottom surface of the liquid guiding member 430. In addition, two support columns 522 are provided on the seat body 520, and a convex buckle 523 is provided on each support column 522. The two convex buckles 523 are arranged oppositely.

[0041] As Figure 5 shown, the fixing bracket 410 includes a plate surface 411 and insertion feet 413, and the number of the insertion feet 413 is two, symmetrically distributed at both ends of the plate surface 411. A through hole 412 is provided on the plate surface 411, and a clamping hole 414 is provided on the two insertion feet 413. The clamping hole 414 can cooperate with the convex buckle 523 on the support column 522 of the seat body 520 so that the fixing bracket 410 is snap-connected to the fixing base 500. The sleeve body 420 includes a socket surface 421 and a socket body 425. A middle hole 422 is provided at the middle position of the socket surface 421, and a socket hole 423 is provided on each of the two side edges. The socket body 425 is a ring-shaped structure. As Figure 3 shown, a cavity 426 is formed inside with a hollow interior. The cavity 426 is used for sleeving the liquid guiding member 430, and the cavity 426 is communicated with the middle hole 422. During installation, the liquid guiding member 430 is placed inside the cavity 426 of the socket body 425, and then the two insertion feet 413 of the fixing bracket 410 are respectively inserted into the two socket holes 423 on the sleeve body 420 in a matching manner, so that the plate surface 411 of the fixing bracket 410 is attached to the socket surface 421 of the sleeve body 420. Then, the insertion feet 413 of the fixing bracket 410 are snap-connected to the support columns 522 of the fixing base 500. As Figure 3 and Figure 5 shown, the outer shape structure of the socket hole 423 is consistent with that of the insertion foot 413, and the specification size of the socket hole 423 is slightly smaller than that of the insertion foot 413. In this way, it can be ensured that the socket hole 423 firmly locks the insertion foot 413 and prevents the two from loosening. At the same time, the transverse length of the liquid guiding member 430 is slightly larger than the transverse length of the cavity 426 to ensure that the socket body 425 clamps the liquid guiding member 430 and prevents the liquid guiding member 430 from loosening from the cavity 426. In a specific embodiment, the kit is made of a sealing material such as soft rubber.

[0042] As Figure 3 shown, after the atomization assembly 400 is assembled, the atomization assembly 400 is clamped at the bottom outlet of the liquid storage chamber 312 for sealing the liquid storage chamber 312. The through hole 412 of the fixing bracket 410 communicates with the middle hole 422 on the sleeve body 420 to form a liquid guiding channel 424. The atomization liquid in the liquid storage chamber 312 can enter the liquid guiding member 430 through the liquid guiding channel 424. The electrode 600 abuts against the heating member 431 on the bottom surface of the liquid guiding member 430. An atomization chamber 440 is formed by enclosing the bottom surface of the liquid guiding member 430, the support column 522, the seat body 520, and the housing 300. Additionally, as Figure 4 shown, the fixing seat 500 is provided with a side wall 513 and a blocking wall 514 at the position of the air inlet hole 511. An air vent 515 is provided at a position where the side wall 513 is close to the blocking wall 514 or at a position where the side wall 513 is connected to the blocking wall 514. The air inlet hole 511 communicates with the atomization chamber 440 through the air vent 515. With the above structural arrangement of the air inlet hole 511, external air laterally enters the atomization chamber 440 through the air inlet hole 511 and the air vent 515. It can be understood that, as Figure 3 shown, when the atomization device 200 works, the heating member 431 at the bottom of the liquid guiding member 430 conducts electricity and generates heat to heat the atomization liquid around the heating member 431, atomizing the atomization liquid. The generated atomized gas is stored in the atomization chamber 440. When the user sucks, external cold air laterally enters the atomization chamber 440 through the air inlet hole 511, and condensate is likely to be generated at the intersection of the hot and cold gases. In the traditional atomization device 200, external air enters the atomization chamber 440 directly from the air inlet hole 511, and the generated condensate is likely to flow out from the air inlet hole 511, thus causing the electrode 600 to short-circuit. Compared with the traditional atomization device 200, in the atomization device 200 of the present invention, external air laterally enters the atomization chamber 440, and the hot and cold gases intersect at the air vent 515. The condensate generated at the air vent 515 will be stored in the concave cavity 516 of the fixing seat 500 and is not likely to flow out from the air inlet hole 511, thereby avoiding the short-circuit of the electrode 600.

[0043] Additionally, as Figure 3 shown, there is a first gap 360 between the lower end of the baffle 310 and the upper end of the fixing seat 500. The seat body 520 is closely attached to the inner wall of the housing 300. As Figure 5 shown, the width of the support column 522 is smaller than the width of the seat body 520, so that there is a second gap 370 between the housing 300 and the support column 522. As Figure 6 shown, the atomization chamber 440 communicates with the air outlet channel 311 through the second gap 370 and the first gap 360 in sequence. Additionally, a liquid accumulation chamber 524 is provided in the fixing seat 500 corresponding to the position of the air outlet channel 311. The liquid accumulation chamber 524 is used to accommodate the condensate from the air outlet channel 311. As Figure 3As shown, the liquid storage chamber 524 is axially offset from the atomization channel, so that a step surface 525 is formed at the connection between the liquid storage chamber 524 and the air outlet channel 311. In this way, it can better ensure that the e-liquid in the liquid storage cavity will not be sucked out again through the air outlet channel 311. In addition, as Figure 3 shown, in a preferred embodiment, the step surface 525 is flush with the first gap 360, or the step surface 525 is located below the first gap 360, so as to ensure that the atomized gas in the atomization cavity 440 enters the air outlet channel 311 through the first gap 360, and further prevent the condensate in the liquid storage chamber 524 from being sucked out.

[0044] As Figure 2 and Figure 3 shown, an annular groove 526 is provided on the outer wall of the fixing seat 500, and an annular sealing ring 700 is arranged in the annular groove 526. The annular sealing ring 700 is in interference fit with the inner wall of the housing 300, so that the fixing seat 500 is hermetically arranged at the lower end of the housing 300, preventing the atomized gas or liquefied e-liquid in the atomization cavity 440 from overflowing from the housing 300, or the outside air from flowing into the atomization cavity 440 and affecting the draw resistance. As Figure 3 and Figure 7 shown, an air outlet 340 is provided at the upper end of the housing 300, and a column 330 is further arranged at the upper end of the housing 300. As Figure 3 shown, the column 330 extends towards the direction of the mouthpiece 100 and there is a gap between the column 330 and the inner top wall of the mouthpiece 100. The column 330 is located on one side of the suction port 110. The column 330 divides the space in the mouthpiece 100 into a gas storage cavity 120 and a liquid storage cavity 130. One end of the gas storage cavity 120 is communicated with the suction port 110, and the other end is communicated with the air outlet 340. During suction, the atomized gas flows out from the air outlet 340 to the suction port 110, and the column 330 blocks the diffusion of the atomized gas to the liquid storage cavity 130. As Figure 3 and Figure 6 shown, a gasket 331 is further provided on the upper end surface of the housing 300, which is used to prevent air from flowing into the air outlet channel 311 from the lower end of the mouthpiece 100, increasing the draw resistance, and preventing the condensate from overflowing from the lower end of the mouthpiece 100; a liquid absorbing member 131 is arranged in the liquid storage cavity 130, which is used to absorb the condensate at the suction port 110. In a specific embodiment, the liquid absorbing member 131 is a condensate absorbing cotton.

[0045] As Figure 7 and Figure 8 shown, long strip columns 332 are provided on both sides of the outer wall of the housing 300, and the long strip columns 332 are higher than the upper end surface of the housing 300. Long strip openings 140 are provided on both sides of the mouthpiece 100. As Figure 1 shown, the long strip columns 332 can be correspondingly clamped in the long strip openings 140. As Figure 7As shown, a card slot 333 is also provided on the outer wall of the housing 300 and the side of the long strip column 332. As Figure 8 shown, convex strips 150 are provided on the inner walls on both sides of the long strip opening 140 of the suction nozzle 100. When the suction nozzle 100 is clamped on the long strip column 332, the convex strips 150 are engaged with the card slots 333 in a matching manner, so that the suction nozzle 100 is snap-connected to the atomization device 200, preventing the suction nozzle 100 from falling off the upper end of the housing 300.

[0046] In addition, as Figure 3 shown, an arc-shaped air passage 341 exists between the air outlet passage 311 and the air outlet 340. On the one hand, the arc-shaped air passage 341 can extend the residence time of the atomized gas in the air outlet passage 311. On the other hand, it can prevent direct air outlet. When the atomized gas collides with the inner wall of the air storage cavity 120, the condensation of small particle aerosol is further accelerated, avoiding the small particle aerosol in the atomized gas from being inhaled into the mouth of the smoker through the air outlet 340 of the suction nozzle 100, the air storage cavity 120 and the suction port 110.

[0047] It should be noted that in the Figure 6 and Figure 7 shown embodiments, the suction nozzle 100 is snap-connected to the housing 300. It can be understood that in other embodiments, the suction nozzle 100 can also be connected to the housing 300 in other ways. In one embodiment, as Figure 9 shown, the upper end of the housing 300 is recessed inward to form a housing groove 350, the upper end of the suction nozzle 100 is recessed inwardly to be provided with a suction nozzle groove 160, and a plug body 161 is provided at the bottom of the suction nozzle groove 160. The plug body 161 is clamped in the housing groove 350. The plug body 161 is integrally formed with the suction nozzle 100, and the suction nozzle 100 is connected to the housing 300 through the plug body 161. The materials of the suction nozzle 100 and the housing 300 are different. The suction nozzle can be made of soft rubber material. During manufacturing, the suction nozzle 100 and the cartridge housing 300 can be integrally injection-molded by a two-shot injection molding machine. As Figure 8 shown, an opening 162 is provided on the side wall 513 of the suction nozzle groove 160 close to the air outlet passage 311. The opening 162 communicates the suction nozzle groove 160 and the air outlet passage 311, and the other end of the suction nozzle groove 160 communicates with the suction port 110. In another embodiment, an opening can also be provided at the upper end of the liquid storage chamber 312. At this time, the plug body 161 has two functions. One is to seal the opening of the liquid storage chamber 312, and the other is to fixedly connect the suction nozzle 100 to the upper end of the housing 300.

[0048] In a specific embodiment, the liquid guiding member 430 is a ceramic core, the atomizing liquid in the liquid storage chamber 312 is e-liquid, and the e-liquid can contact the ceramic core through the liquid guiding channel 424. The ceramic core has many pores, and the e-liquid can penetrate into the pores of the ceramic core. When manually sucking, the electrode 600 connected to the power supply device is energized. The energization of the electrode 600 makes the heating member 431 conduct electricity and generate heat, heating the e-liquid on the periphery of the heating member 431 to atomize the e-liquid, and generating atomized smoke stored in the atomization chamber 440. As Figure 3 shown, when manually sucking, air enters the atomization chamber 440 from the air inlet hole 511 and the ventilation openings 515 on the side, pushing the atomized smoke in the atomization chamber 440 to enter the mouth of the smoker through the air outlet channel 311 and the suction port 110, completing the entire sucking process. During the sucking process, the high-temperature atomized smoke will cool and generate condensate when encountering normal-temperature air or the inner wall of the housing 300. The condensate in the atomization chamber 440 is stored in the concave cavity 516 of the fixing seat 500, the condensate in the air outlet channel 311 is stored in the liquid accumulation chamber 524, and the condensate at the top suction nozzle 100 is stored in the liquid absorbing member 131.

[0049] The electronic cigarette and its atomization device 200 of the present invention, by reasonably setting the structure of the atomization assembly and the mutual cooperation relationship between the atomization assembly and the housing and the fixing seat, enable the entire atomization device 200 to be made thinner and the structure to be more simplified, facilitating assembly or disassembly. In addition, the side air outlet structure also solves the problem that the air outlet channel 311 directly leading to the suction port 110 is likely to allow the user to inhale liquefied liquid. In addition, when the liquid guiding member 430 is a ceramic core, compared with a cotton core, the ceramic core has a better oil locking effect, uniform heating, fast heating speed, and at the same time avoids the problems of carbonization and aging of the cotton core during long-term heating, which affects the taste.

[0050] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described.
