The battery device is provided with a mounting chamber into which the atomizer 100 is engaged, the atomizer 100 is engaged into the mounting chamber to establish an electrical connection with the battery device, and the atomizing device is provided with an airflow channel 16, a heating device 30, and a receiving chamber configured to store tobacco products. The heating device 30 heats the adsorbed tobacco liquid when being driven by the electric power of the battery device to generate smoke for the user to smoke after the smoke flows out through the airflow passage. Here, the tobacco product may be selected from the group consisting of tobacco liquid, tobacco paste, flake-shaped tobacco filament, block-shaped tobacco filament, or a tobacco pellet or a cigarette processed from tobacco filament. In an embodiment of the present invention, the tobacco product is selected from tobacco liquid.

Referring to FIG. 1 to FIG. 5, in the embodiment of the present invention, the atomizer 100 of the electronic cigarette 1000 comprises a substrate 10, a heating device 30, and a cover member 50, wherein the substrate 10 is provided with an mounting space 11, one end of the heating device 30 is inserted into the mounting space 11 and partially extends to the outside through the substrate 10 to form a controlling member 31, and the other end is exposed to the outer surface of the substrate 10, when the controlling member 31 is pressed into the substrate 10 by an external pressing force, the heating device 30 is pushed to move toward the outside of the substrate 10 along the mounting space 11 and partially extends out of the substrate 10, and the cover member 50 is detachably mounted to the substrate 10 and covers the controlling member 31.

According to the atomizer 100 for the electronic cigarette 1000 according to the technical solution of the present invention, the substrate 10 is provided with a mounting space 11, the heating device 30 of the atomizer 100 is engaged into the mounting space 11 to form an assembling member with the substrate 10, and one end of the heating device 30 is exposed to the outside through the substrate 10 to form a controlling portion. When the heating device 30 inside the atomizer 100 is damaged and needs to be replaced, only the controlling portion needs to be pressed, so that the controlling portion pushes the heating device 30 to move toward the outside of the substrate 10 along the mounting space 11 to extend out of the substrate 10, and then is pulled out. A new heating device 30 is then inserted along the mounting space 11 so as to complete the replacement. The operation is simple, and the use cost of the user is effectively saved by only replacing the heating device 30 inside the atomizer 100. At the same time, a cover member 50 detachably mounted to the substrate 10 is provided, so that the controlling member 31 is covered during normal use, effectively preventing the phenomenon that the controlling member 31 is mishandled by an external pressing force when the electronic cigarette 1000 is put into the pocket.

Further, as shown in FIG. 2, in the embodiment of the present invention, the cover member 50 is further provided with a connecting portion 51, when the cover member 50 is mounted to the substrate 10, the connecting portion 51 is engaged with the controlling member 31 for fixedly connecting the cover member 50 with the controlling member 31, and when the cover member 50 is separated from the substrate 10, the controlling member 31 is disengaged from the connecting portion 51. Here, in the present embodiment, the cover member 50 is further provided with a connecting portion 51 so as to be fixedly connected with the controlling portion of the heating device 30 when the cover member 50 is mounted to the substrate 10, effectively enhancing the stability of the connection between the heating device 30 and the substrate 10, preventing the phenomenon that the heating device 30 is abutted against the mounting space 11 to result in a gap during a long-term use so that the heating device 30 is directly disengaged from the substrate 10.

Specifically, as shown in FIG. 2, in the embodiment of the present invention, one of the connecting portion 51 and the controlling member 31 is provided with an engaging groove 511, and the other of the connecting portion 51 and the controlling member 31 is provided with a first elastic sealing ring 311 on a part of the outer peripheral surface thereof, so that the sealing ring is interference fit with the inner groove wall of the engaging groove 511 when being engaged into the engaging groove 511. Here, in the present embodiment, the connecting portion 51 is provided with an engaging groove 511. The end of the controlling member 31 away from the heating device 30 is provided with a groove at the outer circumference thereof into which the first sealing ring 311 is sleeved. When the extending end of the connecting portion 51 is inserted into the engaging groove 511, the first sealing ring 311 is deformed by the pressing force of the inner wall of the engaging groove 511 to be closely fitted and fixed to the groove wall of the inner circumference of the engaging groove 511. At the same time, the elastic interference fit is adopted, which is convenient for the user to pull out the cover member 50.

Specifically, as shown in FIG. 2 or FIG. 3, in the embodiment of the present invention, a stepped limiting portion 32 is formed at a transition between the heating device 30 and the controlling member 31, the substrate 10 is correspondingly provided with an avoidance hole 13 and a limiting groove 14 into which a part of the limiting portion 32 is engaged, when the heating device 30 is mounted to the mounting space 11, the controlling member 31 extends out of the substrate 10 through the avoidance hole 13, and the limiting portion 32 is elastically clamped in the limiting groove 14, so that the heating device 30 is limited to the mounting space 11. Here, in the present embodiment, the controlling member 31 is provided on the extending main body of the heating device 30, a stepped limiting portion 32 is formed at a transition between the heating device 30 and the controlling member 31, and a neck is provided in the limiting portion 32. A second elastic sealing ring 321 is sleeved in the neck. One end of the controlling member 31 is received in the outside of the substrate 10 through the avoidance hole 13, the limiting portion 32 formed by the extending head end of the controlling member 31 is engaged into the limiting groove 14, and the second sealing ring 321 is fitted to the inner groove wall surface of the limiting groove 14 and is elastically clamped in the limiting groove 14, so that the heating device 30 is detachably mounted in the mounting space 11. The connection is relatively stable and external dust is effectively prevented from flowing into the mounting space 11 through the avoidance hole 13. When the disassembly is required, the controlling member 31 only needs to be pressed to move the controlling member 31 to the inside of the mounting space 11, so that the limiting portion 32 sleeved with the second sealing ring 321 is disengaged from the limiting groove 14, and the heating device 30 is pulled out from the substrate 10. No screws, snaps or threads are required for fixing, which is convenient to mount and disassemble.

Further, as shown in FIG. 3, in the embodiment of the present invention, the end of the heat-generating device 30 away from the controlling member 31 is further provided with an elastic limiting base 33, and when the heating device 30 is mounted to the mounting space 11, an outer peripheral surface of the limiting base 33 is interference fit with an inner wall of the mounting space 11, so that the heating device 30 is limited to the substrate 10. Here, in the present embodiment, the end of the heating device 30 away from the limiting portion 32 is sleeved with the limiting base 33. The limiting base 33 may be made of elastic silicone or elastic plastic. In the present embodiment, the elastic silicone is used. The outer peripheral surface of the limiting base 33 is fitted to the inner wall of the mounting space 11 and is elastically abutted against the inner wall of the mounting space 11. The end of the heating device 30 provided with the controlling member 31 and the end opposite to the controlling member 31 are elastically clamped to the substrate 10 to further enhance the connection strength between the heating device 30 and the substrate 10, preventing the phenomenon that the heating device 30 is disengaged from the substrate 10 by the small external force.

Specifically, as shown in FIG. 2, in the embodiment of the present invention, the substrate 10 is further convexly provided with a supporting member 12 at both sides adjacent to the controlling member 31, and the outer peripheral surface of the supporting member 12 is closely fitted to the inner wall of the cover member 50 so that the cover member 50 is fixedly mounted to the substrate 10. Here, in the present embodiment, the substrate 10 is further convexly provided with a supporting member 12 at both sides adjacent to the controlling member 31. A supporting space is formed between the two supporting members 12, and the surface of the extending end of the supporting member 12 is flush with or higher than the surface of the controlling member 31 extending beyond the substrate 10, so that the controlling member 31 is received in the supporting space. When the cover member 50 is disengaged from the substrate 10, if the pressing force applied by the controlling member 31 is biased, or the applied force has a large area, the object that applies the external pressure is abutted against the supporting member 12 to restrict the pressing force from being applied on the controlling member 31, thereby effectively preventing the phenomenon that when the cover member 50 is disengaged from the substrate 10, the controlling member 31 is placed in the pocket and is erroneously pressed into the substrate 10 by the external pressing force so that the heating device 30 is disengaged from the substrate 10. At the same time, the outer peripheral surface of the supporting member 12 is closely fitted to the inner wall of the cover member 50, effectively reinforcing the friction between the cover member 50 and the supporting member 12, thereby enhancing the connection strength between cover member 50 and the substrate 10, and preventing the phenomenon that the cover is disengaged from the substrate 10 by a small external force.

Specifically, as shown in FIG. 4, in the embodiment of the present invention, the thickness of the supporting member 12 is gradually increased from the end of the supporting member 12 away from the substrate 10 toward the end of the substrate 10; here, in the present embodiment, the supporting member 12 is integrally formed with the substrate 10, and while the supporting member 12 is extended outwardly from one end of the substrate 10, the thickness value H of the supporting member 12 is gradually reduced and the overall shape is curved. When the substrate 10 is inserted into the inner chamber of the cover member 50, the end of the supporting member 12 having a small thickness is first inserted into the cover member 50. As the substrate 10 is gradually inserted into the cover member 50, the thickness of the supporting member 12 is gradually increased, so that the outer peripheral surface of the supporting member 12 is gradually closely fitted to the inner wall of the cover member 50, which is convenient for the user to mount and disassemble.

Further, as shown in FIG. 1 or FIG. 2, in the embodiment of the present invention, the supporting member 12 is provided with two notches 121 in the engaging direction in which the substrate 10 is inserted into the cover member 50, so that when the cover member 50 is mounted to the substrate 10, the outer surface of the supporting member 12 is pressed to be elastically deformed toward the notches 121. Here, in the present embodiment, the size value of the supporting member 12 is larger than the size value of the corresponding position of the inner wall chamber of the cover member 50. The supporting member 12 is provided with two notches 121 in the engaging direction in which the substrate 10 is inserted into the cover member 50, so that the portion of the supporting member 12 provided with the notches 121 forms an elastic wall that can swing toward the notches 121. When the supporting member 12 is inserted into the cover member 50, the elastic wall is pressed to move toward the inside of the notches 121, and the elastic wall is closely fitted to the inner wall of the cover member 50 under the elastic restoring force, thereby further facilitating mounting the cover member 50 to the substrate 10 and further enhancing the connection strength between the cover member 50 and the substrate 10 at the same time.

Specifically, as shown in FIG. 2, in the embodiment of the present invention, the cover member 50 is provided with two air inlets 52, the two notches 121 are communicated with the outside airflow through the two air inlets 52, respectively, the substrate 10 is provided with an airflow passage 16, one end of the airflow passage 16 is communicated with the two notches 121, and the other end is communicated with an internal chamber of the heating device 30 for providing a working airflow to the heating device 30. Here, in the present embodiment, the cover member 50 is provided with two air inlets 52, and the substrate 10 is provided with an airflow passage 16. Air passing holes 1211 communicated with the airflow passage 16 are provided in the two notches 121. When the cover member 50 is mounted to the substrate 10, the external airflow enters the notch 121 from the air inlet 52, and then enters the airflow passage 16 through the air passing hole 1211 to flow into the inner wall chamber of the heating device 30 for providing a working airflow to the heating device 30.

Specifically, as shown in FIG. 2, in the embodiment of the present invention, the substrate 10 is provided with an oil storage chamber 15 communicated with the mounting space 11, the heating device 30 comprises a heating base 34 and an air outlet pipe, the heating base 34 is provided with an atomizing chamber 341 communicated with the airflow passage 16 and an oil guiding hole 342 communicated with the atomizing chamber 341, the air outlet pipe is mounted to the heating base 34 and is communicated with the atomizing chamber 341, when the heating device 30 is mounted to the mounting space 11, the oil guiding hole 342 is communicated with the oil storage chamber 15, and the air outlet pipe extends out of the substrate 10 to form the controlling member 31. Here, in the present embodiment, the heating device 30 comprises a heating base 34 and an air outlet pipe fixedly mounted to the heating base 34. The heating base 34 is provided with an atomizing chamber 341 and a heating element therein. The tobacco liquid in the oil storage chamber 15 flows into the atomizing chamber 341 through the oil guiding hole 342, and the heating element heats the tobacco liquid in the atomizing chamber 341 when being driven by the electric power of the battery device to generate smoke. The air outlet pipe is hollow, and one end of the air outlet pipe is communicated with the atomizing chamber 341, and the other end passes outside the substrate 10 to form a controlling member 31. The connecting portion 51 provided by the cover member 50 has a through hole to form a suction port 53 for the user to smoke. The manner of forming the controlling member 31 through the air outlet pipe eliminates the need to additionally provide the controlling member 31, effectively saving the internal occupied space, thereby reducing the product volume and facilitating the user to carry.

Further, as shown in FIG. 3, in the embodiment of the present invention, the heating base 34 is provided with an air inlet 343, the limiting base 33 is provided with an air inlet passage 332, when the heating base 34 is mounted to the limiting base 33, the air inlet passage 332 is communicated with the air inlet 343, and when the heating device 30 is mounted to the mounting space 11, the limiting base 33 is partially inserted into the airflow passage 16 of the substrate 10, so that the airflow passage 16 is communicated with the air inlet 343 through the air inlet passage 332. Here, it can be understood that the suction port 53 of the electronic cigarette 1000 is generally provided such that the top end is prevented from being contaminated by external articles when placed. In the present embodiment, the outer circumference of the end of the heating base 34 away from the air outlet pipe is provided with an air inlet 343, and the limiting base 33 is provided with an air inlet passage 332. When the limiting base 33 is sleeved to the heating base 34, the air inlet passage 332 is communicated with the air inlet 343, and the limiting base 33 is further provided with an air guiding column 331 communicated with the air inlet passage 332. When the heating device 30 is mounted to the substrate 10, the air guiding column 331 is engaged into the airflow passage 16 provided in the substrate 10. Therefore, the external air flows into the notch 121 through the air inlet 52, flows into the airflow passage 16 through the air passing hole 1211, and finally flows into the air inlet passage 332 through the air guiding column 331 to be communicated with the air inlet 343 of the heating base 34 to form a manner that air enters from the top of the electronic cigarette 1000. Therefore, when the user smokes, under the force of gravity, the tobacco liquid cannot flow into the air passing hole 1211 through the airflow passage 16 to result in oil leakage, effectively preventing the phenomenon that the atomizer 100 leaks oil into the battery device to damage the electronic components inside the battery device.

It can be understood that, in the actual application, the airflow passage 16 can be provided with two air guiding pipes in the substrate 10. One end of the two air guiding pipes is communicated with the two air passing holes 1211, and the other end is communicated with the two air guiding column 331 to form two independent airflow channels 16. Two air guiding pipes are also provided inside the substrate 10. One end of the two air guiding pipes is communicated with the air guiding column 331 after being communicated with each other, and the other end is communicated with the two air passing holes 1211 to form the airflow passage 16. The above manner is within the scope of protection of the present invention.

Referring to FIG. 5, the present invention further provides an electronic cigarette 1000. The electronic cigarette 1000 comprises a battery device and an atomizer 100 of the electronic cigarette 1000.
