[0002] The present application relates to the field of e-cigarettes, and in particular to a detachable and replaceable battery e-cigarette.BACKGROUND

[0003] As an electronic product that simulates a conventional cigarette, an e-cigarette is highly similar to a conventional cigarette in terms of appearance, the state of aerosol generated during use, and the user experience, and is therefore widely used as a substitute for conventional cigarettes. An e-cigarette generally includes a housing, an atomizing assembly, and an electronic control assembly. The housing is provided with an air inlet hole and a suction hole. The atomizing assembly is disposed inside the housing and is configured to atomize e-liquid into aerosol. The electronic control assembly supplies power to and controls the atomizing assembly. During use, external air enters the atomizing assembly through the air inlet hole, carries the aerosol generated by heating the e-liquid in the atomizing assembly, and then enters the user’s mouth through the suction hole. The electronic control assembly generally includes a battery module.

[0004] In existing e-cigarettes, the battery module is generally fixedly disposed inside the housing and is not detachable. As a result, when the e-cigarette is discarded, it is difficult to disassemble and recycle the battery module, such that the discarded battery module may easily cause environmental pollution. In addition, when the battery module is damaged, the user cannot easily and quickly detach and replace the battery module.

[0005] In order to make removal and replacement of the battery module easier and more convenient, the present application provides a detachable and replaceable battery e-cigarette.

[0015] Optionally, the atomizing assembly includes a central post, oil-conducting cotton, an atomizing core, and filter cotton. The central post is disposed in the main body. The central post is provided with an oil-conducting hole for oil feeding. The atomizing core is disposed inside the central post. The oil-conducting cotton is disposed on the central post and located between the central post and the atomizing core. The filter cotton is disposed on the central post, located at the bottom of the atomizing core, and abuts against the atomizing core, and the filter cotton abuts against the oil-conducting cotton.

[0016] The main body is provided with an oil storage chamber, and the liquid in the oil storage chamber enters the atomizing assembly through the oil-conducting hole for atomization.

[0017] Optionally, the hole body of the suction hole is provided with mouthpiece oil-absorbing cotton, and the mouthpiece oil-absorbing cotton is configured to absorb oil in the aerosol passing through the suction hole.

[0018] Optionally, the main body is provided with an oil-blocking block, and the oil-blocking block is provided with an oil-blocking groove.

[0019] The oil-blocking block is fixedly provided with an air guide tube. After airflow enters the e-cigarette through the air inlet hole, the airflow enters the atomizing assembly through the air guide tube.

[0020] The circuit board is fixedly provided with and electrically connected to a light-emitting module. The main body is provided with a light-transmitting hole, and light emitted by the light-emitting module passes through the oil-blocking block and shines out of the main body through the light-transmitting hole.

[0021] The circuit board is fixedly provided with and electrically connected to a sensing module. The oil-blocking block is provided with a sensing groove. The sensing module extends through the sensing groove, and the sensing groove communicates with the suction hole.

[0022] In summary, the present application achieves at least one of the following beneficial technical effects:

[0023] When the user discards the e-cigarette and needs to disassemble the battery module for recycling, or when the battery module of the e-cigarette is damaged and needs to be detached and replaced, the cover body is detached from the main body, such that the cover body is disconnected from the main body and the battery chamber is opened. Accordingly, the user can remove the battery module from the battery chamber. After the battery module is removed from the battery chamber, the battery module is disconnected from the circuit board, thereby completing removal of the battery module. If the user needs to replace the battery module with a new one, the new battery module is reinserted into the battery chamber and the cover body is reconnected to the main body, thereby completing replacement of the battery module. It should be understood that when the battery module is inserted into the battery chamber, the battery module is electrically connected to the circuit board, thereby making removal and replacement of the battery module easier and more convenient. This improves upon the existing situation in which the battery module of an e-cigarette is generally fixed inside the housing and cannot be removed, which makes disassembly and recycling difficult when the e-cigarette is discarded, may cause environmental pollution due to discarded battery modules, and prevents the user from easily and quickly replacing a damaged battery module.BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present application will be further described in detail below with reference to FIGS. 1 to 9.

[0035] An embodiment of the present application discloses a detachable and replaceable battery e-cigarette. Referring to FIGS. 1 to 4, the detachable and replaceable battery e-cigarette includes a housing 1, an atomizing assembly 2, and an electronic control assembly 3. The housing 1 is provided with an air inlet hole 1a and a suction hole 1b. The atomizing assembly 2 is disposed in the housing 1 and is configured to atomize e-liquid into aerosol, and both the air inlet hole 1a and the suction hole 1b are in communication with the atomizing assembly 2. The housing 1 includes a main body 11 and a cover body 12. The main body 11 is provided with a battery chamber 111. The cover body 12 is detachably connected to the main body 11 and closes the battery chamber 111. The electronic control assembly 3 includes a circuit board 31 and a battery module 32. The circuit board 31 is disposed in the main body 11, and the battery module 32 is disposed in the battery chamber 111. When the battery module 32 is inserted into the battery chamber 111, the battery module 32 is electrically connected to the circuit board 31. When the battery module 32 is removed from the battery chamber 111, the battery module 32 is disconnected from the circuit board 31.

[0036] Referring to FIGS. 2 and 5, in the present embodiment, the main body 11 is provided with a snap-fit groove 112, and the cover body 12 is provided with a snap-fit block 121. When the main body 11 and the cover body 12 are detachably connected, the snap-fit block 121 extends into and snap-fit engages with the snap-fit groove 112, thereby realizing detachable connection between the main body 11 and the cover body 12. In a further embodiment, the snap-fit groove 112 includes a snap-fit section 1121 and a sliding section 1122, and the snap-fit section 1121 communicates with the sliding section 1122. After the snap-fit block 121 slides from the sliding section 1122 to the snap-fit section 1121, the snap-fit block 121 snap-fit engages with the snap-fit groove 112. After the snap-fit block 121 slides from the snap-fit section 1121 to the sliding section 1122, the snap-fit block 121 disengages from the snap-fit groove 112. It should be understood that the snap-fit block 121 can enter the snap-fit groove 112 from the sliding section 1122. In a further embodiment, a snap-fit protrusion 11211 is fixedly disposed in the groove body of the snap-fit section 1121. When the snap-fit block 121 slides to the snap-fit section 1121, the snap-fit block 121 abuts against the snap-fit protrusion 11211 so as to prevent the snap-fit block 121 from sliding from the snap-fit section 1121 to the sliding section 1122, thereby making the snap-fit engagement between the snap-fit block 121 and the snap-fit groove 112 more stable and the fit between the main body 11 and the cover body 12 more stable. It should be understood that when the user applies a relatively large force to drive the snap-fit block 121 to slide along the snap-fit groove 112, the snap-fit block 121 can disengage from the snap-fit protrusion 11211 and thus slide from the snap-fit section 1121 to the sliding section 1122. In a still further embodiment, the cover body 12 is fixedly provided with a sliding block 122, and the main body 11 is provided with a sliding groove 117. When the snap-fit block 121 slides from the snap-fit section 1121 to the sliding section 1122, the sliding block 122 slides along the groove body of the sliding groove 117, thereby making sliding of the snap-fit block 121 more stable.

[0037] Specifically, when the cover body 12 needs to be detached from the main body 11 so that the battery chamber 111 can be opened, the cover body 12 is driven to rotate relative to the main body 11, such that the cover body 12 drives the snap-fit block 121 to slide along the snap-fit groove 112. In this way, the snap-fit block 121 slides from the snap-fit section 1121 to the sliding section 1122, thereby disengaging the cover body 12 from the main body 11 so that the cover body 12 can be detached from the main body 11. When the snap-fit block 121 slides within the snap-fit section 1121, the sliding block 122 slides along the sliding groove 117 to guide movement of the snap-fit block 121, thereby improving sliding stability of the snap-fit block 121.

[0038] Referring to FIGS. 2 and 4, in the present embodiment, the cover body 12 is provided with bottom oil-absorbing cotton 123. When the cover body 12 is connected to the housing 1, the bottom oil-absorbing cotton 123 abuts against the battery module 32, thereby ensuring stability of the battery module 32 when positioned in the battery chamber 111. In addition, it should be understood that the bottom oil-absorbing cotton 123 can also absorb liquid flowing to the cover body 12, thereby keeping the battery module 32 dry.

[0039] Referring to FIG. 6, in the present embodiment, the circuit board 31 is fixedly provided with and electrically connected to two conductive metal pins 311, and the battery module 32 is fixedly provided with and electrically connected to two conductive metal rings 321. The two conductive metal rings 321 are coaxially arranged. When the battery module 32 is inserted into the battery chamber 111, the two conductive metal pins 311 respectively abut against and are electrically connected to the two conductive metal rings 321, thereby realizing electrical connection between the battery module 32 and the circuit board 31. This makes electrical connection between the battery module 32 and the circuit board 31 simpler and more convenient, thereby making removal and replacement of the battery module 32 easier and more convenient.

[0040] Referring to FIG. 7, in the present embodiment, the hole body of the suction hole 1b is provided with mouthpiece oil-absorbing cotton 1b1. The mouthpiece oil-absorbing cotton 1b1 is configured to absorb oil contained in the aerosol passing through the suction hole 1b, thereby making the aerosol passing through the suction hole 1b purer and improving the taste of the aerosol.

[0041] Referring to FIGS. 2 and 3, in the present embodiment, the atomizing assembly 2 includes a central post 21, oil-conducting cotton 22, an atomizing core 23, and filter cotton 24. The central post 21 is disposed in the main body 11. The central post 21 is provided with an oil-conducting hole 211 for introducing oil. The atomizing core 23 is disposed inside the central post 21. The oil-conducting cotton 22 is disposed on the central post 21 and located between the central post 21 and the atomizing core 23. The filter cotton 24 is disposed on the central post 21, located at the bottom of the atomizing core 23, and abuts against the atomizing core 23, and the filter cotton 24 abuts against the oil-conducting cotton 22. The main body 11 is provided with an oil storage chamber 113, and liquid in the oil storage chamber 113 enters the atomizing assembly 2 through the oil-conducting hole 211 for atomization. Specifically, the oil storage chamber 113 is located between the main body 11 and the central post 21, and a sealing block 114 is disposed between the main body 11 and the central post 21 so that liquid in the oil storage chamber 113 cannot seep out through the gap between the main body 11 and the central post 21. It should be understood that the atomizing core 23 is internally integrated with a heating wire for heating, and the heating wire is electrically connected to the circuit board 31 so as to heat the liquid entering the atomizing assembly 2 into aerosol for user inhalation.

[0042] Referring to FIGS. 8 and 9, in the present embodiment, the main body 11 is provided with an oil-blocking block 115, and the oil-blocking block 115 is provided with an oil-blocking groove 1151. The oil-blocking block 115 is fixedly provided with an air guide tube 1152. After airflow enters the e-cigarette through the air inlet hole 1a, the airflow enters the atomizing assembly 2 through the air guide tube 1152. The circuit board 31 is fixedly provided with and electrically connected to a light-emitting module 312. The main body 11 is provided with a light-transmitting hole 116, and light emitted by the light-emitting module 312 passes through the oil-blocking block 115 and shines out of the main body 11 through the light-transmitting hole 116. The circuit board 31 is fixedly provided with and electrically connected to a sensing module 313. The oil-blocking block 115 is provided with a sensing groove 1153, and the sensing module 313 extends through the sensing groove 1153. The sensing groove 1153 communicates with the suction hole 1b. The sensing module 313 is configured to sense airflow in the suction hole 1b. When the user inhales through the suction hole 1b so that airflow in the suction hole 1b flows rapidly, the sensing module 313 detects the user’s inhalation action through the rapid airflow and transmits a corresponding signal to the circuit board 31. The circuit board 31 controls the atomizing assembly 2 to operate and atomize the liquid into aerosol for user inhalation.

[0043] The implementation principle of the detachable and replaceable battery e-cigarette according to the embodiment of the present application is as follows. When the user discards the e-cigarette and needs to detach the battery module 32 for recycling, or when the battery module 32 of the e-cigarette is damaged and needs to be detached and replaced, the cover body 12 is detached from the main body 11, such that the cover body 12 is disconnected from the main body 11 and the battery chamber 111 is opened. Accordingly, the user can detach the battery module 32 from the battery chamber 111 and remove it from the battery chamber 111. After the battery module 32 is removed from the battery chamber 111, the battery module 32 is disconnected from the circuit board 31, thereby completing removal of the battery module 32. If the user needs to replace the battery module 32 with a new battery module 32, the new battery module 32 is reinserted into the battery chamber 111 and the cover body 12 is reconnected to the main body 11, thereby completing removal and replacement of the battery module 32. It should be understood that when the battery module 32 is inserted into the battery chamber 111, the battery module 32 is electrically connected to the circuit board 31, thereby making removal and replacement of the battery module 32 easier and more convenient. This improves upon the problem in existing e-cigarettes in which the battery module 32 is generally fixed inside the housing 1 and cannot be removed, thereby making disassembly and recycling difficult when the e-cigarette is discarded, causing discarded battery modules 32 to easily pollute the environment, and preventing the user from easily and quickly detaching and replacing the battery module 32 when it is damaged.

[0044] The foregoing embodiments are merely preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall fall within the scope of protection of the present application.
