[0002] With the rapid development of science and technology and the economy, it is inevitable that e-cigarettes will gradually replace cigarettes. E-cigarettes have a similar appearance and taste to cigarettes, and can produce smoke just like real cigarettes. Moreover, e-cigarettes do not contain harmful components such as tar and particulate matter, and do not produce lingering secondhand smoke. They do not affect the health of smokers or those around them, and are therefore very popular.

[0003] Existing electronic cigarettes include a casing, a liquid reservoir, an atomizer core, a control board, and a light source. The casing includes an outer tube and a translucent end cap at the end of the outer tube. The liquid reservoir is located inside the outer tube, the atomizer core is located inside the liquid reservoir, the control board is located inside the outer tube and electrically connected to the atomizer core, and the light source is located on the side of the control board facing the end cap. When smoking, the light source emits light, which shines out from the translucent end cap to mimic a real cigarette. However, in this structure, when the light source is emitting light, the emitted light shines directly into the eyes of people around the user, creating a glaring bright spot that results in a poor user experience.

[0027] Please refer to Figures 1-9 This application provides an electronic atomizing device, which includes an oil cup assembly 1, an atomizing assembly 2, and a battery assembly 3. The oil cup assembly 1 is detachably connected to the atomizing assembly 2 and is used to provide e-liquid. It includes an oil storage sleeve 11, a second sealing seat 12, a sealing plug 13, and a support base 14. The oil storage sleeve 11 has a main oil storage chamber 111 for storing e-liquid for atomization by the atomizing assembly 2. Preferably, the oil storage sleeve 11 is made of a transparent material, thus facilitating user observation of the remaining e-liquid in the main oil storage chamber 111. The second sealing seat 12 is inserted into one end of the main oil storage chamber 111 to seal the e-liquid within it.

[0028] The second sealing seat 12 is provided with an oil outlet 121 and an oil filling hole 122. The oil outlet 121 penetrates the two opposite end faces of the second sealing seat 12 and communicates with the main oil storage chamber 111. A sealing piece 123 is provided inside the oil outlet 121 to prevent the e-liquid in the main oil storage chamber 111 from flowing out of the oil outlet 121. The oil filling hole 122 is arranged side by side with the oil outlet 121 at intervals. The oil filling hole 122 penetrates the two opposite end faces of the second sealing seat 12 and communicates with the main oil storage chamber 111.

[0029] During production, e-liquid is injected into the main oil storage chamber 111 through the oil injection hole 122. The first end of the sealing plug 13 is inserted into the oil injection hole 122, and the second end of the sealing plug 13 abuts against the support base 14. Therefore, the sealing plug 13 is not easily removed, preventing unauthorized removal and subsequent injection of unknown liquids, thus improving safety. The support base 14 is fitted onto one end of the second sealing seat 12 and connected to the oil storage sleeve 11 to prevent the second sealing seat 12 from falling out of the oil storage sleeve 11.

[0030] The electronic atomizing device of this embodiment includes a first state and a second state. In the first state, the oil cup assembly 1 and the atomizing assembly 2 are separated, and the sealing plate 123 prevents the e-liquid in the main oil storage chamber 111 from flowing out of the oil outlet 121. That is, before the user uses it, the oil cup assembly 1 and the atomizing assembly 2 are not connected together, and they can be placed in the same packaging box or separately in different packaging boxes. When the user needs to smoke, the oil cup assembly 1 and the atomizing assembly 2 are connected, and the atomizing assembly 2 passes through the sealing plate 123 to communicate with the main oil storage chamber 111. The e-liquid in the main oil storage chamber 111 flows into the atomizing assembly 2 through the oil outlet 121.

[0031] The atomizing assembly 2 is connected to the battery assembly 3 and is used to atomize e-liquid. It includes an atomizing cup 21, a porous wicking element 22, an atomizing base 23, an atomizing coil 24, and a mounting base 25. The atomizing cup 21 is located inside one end of the battery assembly 3. An oil guide tube 211 is provided on the end face of the atomizing cup 21 facing the oil cup assembly 1. A secondary oil storage chamber 212, communicating with the oil guide tube 211, is provided inside the atomizing cup 21. In the first state, the secondary oil storage chamber 212 stores e-liquid, thus effectively preventing insufficient e-liquid supply and dry burning of the atomizing coil 24 when vaping begins. In the second state, the oil guide tube 211 passes through the sealing plate 123 to communicate with the main oil storage chamber 111, and the e-liquid in the main oil storage chamber 111 flows to the secondary oil storage chamber 212 through the oil guide tube 211.

[0032] A porous wicking element 22 is located within the secondary oil storage chamber 212 to absorb e-liquid. It can be made of materials such as cotton or porous ceramic. The porous wicking element 22 effectively absorbs the e-liquid, thus preventing leakage. An atomizer base 23 is inserted into the opening of the secondary oil storage chamber 212 to seal it. It can be made of materials such as silicone or rubber, thus improving sealing performance. An atomizer coil 24 is located within the secondary oil storage chamber 212 and inserted into the atomizer base 23. It atomizes the e-liquid within the secondary oil storage chamber 212. It can consist of a fixing tube, a wicking element, and a heating element in contact with the wicking element. The wicking element can be made of materials such as cotton, non-woven fabric, or porous ceramic, and the heating element can be a heating mesh or heating wire. The fixing seat 25 is fitted onto one end of the atomizing seat 23 and connected to the atomizing cup 21. A first oil-absorbing cotton block 26 is provided between the fixing seat 25 and the atomizing seat 23. The first oil-absorbing cotton block 26 is used to absorb leaked e-liquid.

[0033] The battery assembly 3 includes a battery sleeve 31, an end cap 32, a fixing bracket 33, a control board 34, a charging interface 35, and a battery 36. The first end and the second end of the battery sleeve 31 are positioned opposite each other. The end cap 32 covers the first end of the battery sleeve 31 and includes an end wall and a side wall connected to the end wall. The side wall has a light guide hole 321. The atomizing assembly 2 is located inside the second end of the battery sleeve 31. The fixing bracket 33 is located within the space formed by the battery sleeve 31 and the end cap 32. It has a second clearance hole 331, a first air guide groove 332, a second air guide groove 333, and a fixing hole 334. The wall of the fixing hole 334 has a limiting ring 3341. The control board 34 is located inside the battery sleeve 31 and mounted on the fixing bracket 33. The control board 34 is electrically connected to the atomizing core 24 and the battery 36, and is used to control the battery 36 to supply power to the atomizing core 24 when the user smokes. The control board 34 is provided with a first clearance hole 341 and a first air guide hole 342. The second clearance hole 331 is positioned corresponding to the first clearance hole 341 and is provided at intervals.

[0034] The charging interface 35 is fixed to one end of the control board 34 and located inside the end cover 32. The battery 36 is located inside the battery sleeve 31 and passes through the first clearance hole 341 and the second clearance hole 331. Therefore, the cross-sectional area of ​​the battery sleeve 31 can be reduced, resulting in a smaller overall size, making it easier for users to carry, and the battery 36 is positioned more reliably. The first air guide groove 332 is located at the end face of the fixed bracket 33 and communicates with the atomizing component 2. The first air guide groove 332 contains a second oil-absorbing cotton block 37, which is used to absorb e-liquid leaking from the atomizing component 2. The second air guide groove 333 is located on the side of the first air guide groove 332 facing away from the atomizing component 2 and communicates with the first air guide groove 332.

[0035] The battery assembly 3 also includes a light source 381 and a light guide 382. The light source 381 is mounted on the control board 34 and is used to emit light to the light guide 382; it can be a light-emitting diode (LED). The light guide 382 is mounted on the mounting bracket 33 and is used to guide the light emitted by the light source 381 to the light guide hole 321, thus allowing observation of the electronic atomization device's operating status and adding to the enjoyment. The first end of the light guide 382 is inserted into the light guide hole 321, and the second end of the light guide 382 is fixed to the mounting bracket 33, with the end face of the second end of the light guide 382 facing the light source 381. This ensures not only reliable fixation but also better light guidance.

[0036] In this embodiment, the end face of the light guide 382 facing the light source 381 is the light-inlet surface. Since the light-inlet surface is flat, it is less prone to dust accumulation. The light-emitting diodes are spaced apart from the light-inlet surface, resulting in relatively small intensity differences in the areas of the light entering the light-inlet surface. The end face of the light guide 382 facing away from the light source 381 is the light-emitting surface. Since the light-emitting surface is curved, it can scatter the light. When the battery assembly 3 is placed vertically with the end cap 32 facing downwards, the width of the upper end of the light guide 382 is greater than the width of the lower end, and the height of the light source 381 is higher than the geometric center of the light guide 382, ​​thus preventing excessive brightness at the lower end of the light guide 382. Furthermore, the light guide 382 is provided with a limiting step 3821. The light guide 382 passes through the fixing hole 334, and the limiting ring 3341 abuts against the limiting step 3821 to prevent the light guide 382 from moving towards the light source 381. Therefore, it is easier to assemble the light guide properly.

[0037] When the battery assembly 3 is placed vertically with the end cap 32 facing downwards, the distance from the upper edge of the light-emitting surface to the light source 381 is greater than the distance from the lower edge of the light-emitting surface to the light source 382. The battery 36 is located between the atomizing assembly 2 and the light source 381, and the orthographic projection of the light source 381 onto the plane containing the end face of the battery 36 lies within the end face of the battery 36. Therefore, oil droplets are less likely to fall onto the light source 381, thus better protecting the light source 381.

[0038] The battery assembly 3 also includes an airflow sensor 383 and a first sealing seat 384. The airflow sensor 383 is mounted on the first side of the control board 34 and covers the first end opening of the first air guide hole 342. The first sealing seat 384 is provided with a second air guide hole 3841. The first sealing seat 384 is mounted on the second side of the control board 34 and covers the second end opening of the first air guide hole 342 and the opening of the second air guide groove 333. The airflow sensor 383 communicates with the second air guide groove 333 through the first air guide hole 342 and the second air guide hole 3841. This structure has the advantages of good sealing performance and easy assembly. In this embodiment, when the electronic atomizing device is placed vertically and the end cap 32 faces downward, the height of the second air guide hole 3841 is higher than the bottom wall of the second air guide groove 333. Therefore, leaked e-liquid is less likely to flow into the airflow sensor 383, extending the service life of the electronic atomizing device.

[0039] During assembly, the battery 36 is first inserted into the first clearance hole 341 of the control board 34, and then the battery 36 and the control board 34 are inserted together into the battery sleeve 31. The two do not interfere with each other, thus facilitating assembly. Furthermore, compared to the parallel arrangement of the battery 36 and the control board 34, this invention is smaller and easier to carry.

[0040] In summary, this invention uses a light source 381 mounted on a control board 34 to emit light from a light guide 382. The light guide 382 is mounted on a fixed bracket 33 and extends into the light guide hole. The end face of the light guide 382 facing the light source 381 is the light-inlet surface, which is flat. The end face of the light guide 382 facing away from the light source 381 is the light-outlet surface, which is curved. When the battery assembly 3 is placed vertically and the end cap 32 faces downwards, the width of the upper end of the light guide 382 is greater than the width of the lower end, and the height of the light source 381 is higher than the geometric center of the light guide 382. Therefore, the light emitted by the light source 381 is emitted relatively evenly from the side, preventing glare for those nearby and providing a good user experience.
