Description

Technical Field

[0001] The present application relates to the field of electronic atomizers, and in particular to an electronic atomizer that is easy to fill with oil. Background Art

[0002] An electronic cigarette is an electronic device, usually composed of a shell, a cigarette cartridge, a flue, an atomization assembly, a battery and other components. Its working principle is to heat the electronic cigarette oil through a heater, thereby atomizing the oil to produce smoke. Users obtain nicotine or other chemicals by inhaling this smoke without burning tobacco, thus playing the role of tobacco substitute. At the same time, different flavors of flavors can also be added to the oil to enhance the user's experience of using the electronic cigarette.

[0003] There is an existing electronic atomizer in which the cigarette cartridge is detachably connected to the shell. If the cigarette oil in the current cigarette cartridge is used up, the cigarette cartridge needs to be removed along the shell and replaced with a new one. The operation is simple. Compared with disposable electronic atomizers, electronic atomizers with replaceable cigarette cartridges have a longer service life and are conducive to promotion and application.

[0004] However, in actual application, the cigarette cartridge needs to be disassembled along the shell, so that there is a certain gap between the cigarette cartridge and the shell. Since the cigarette oil in the cigarette cartridge is in a fluid state, the cigarette oil will flow along the gap to the outer wall of the shell, which is not conducive to the smoker's grip, reducing the smoker's user experience, and there is room for improvement. Utility Model Content

[0005] In order to facilitate the oil filling of the electronic atomizer, the present application provides an electronic atomizer that is easy to fill with oil.

[0006] The electronic atomizer provided in this application is easy to fill with oil and adopts the following technical solution:

[0007] An electronic atomizer that is easy to fill with oil includes a shell, a cigarette cartridge, and an atomizer assembly. The cigarette cartridge is fixedly connected to the shell, the atomizer assembly is arranged in the shell, the atomizer assembly is used to atomize the tobacco oil in the cigarette cartridge, the cigarette cartridge is provided with an inhalation nozzle, the inhalation nozzle is used for a smoker to inhale the atomized tobacco oil, the cigarette cartridge is detachably provided with an oil filling box, the oil filling box is used to store tobacco oil, and when the oil filling box is set on the cigarette cartridge, the tobacco oil in the oil filling box will flow into the cigarette cartridge.

[0008] By adopting the above technical solution, the oil in the cigarette cartridge is atomized by the atomizer assembly. Since the cigarette cartridge is fixedly connected to the shell and an inhalation nozzle is provided on the cigarette cartridge, the user can inhale the oil atomized by the atomizer assembly through the inhalation nozzle. At the same time, a detachable oil filling box is provided on the cigarette cartridge. When the oil in the cigarette cartridge is used up, the oil filling box can be disassembled along the cigarette cartridge and replaced with a new one. The operation is simple and there is no need to replace the entire cigarette cartridge, which plays a positive guiding role in improving the convenience of filling the electronic atomizer with oil.

[0009] Preferably, a limiting hole is provided on the cigarette cartridge, the contour of the limiting hole is adapted to the contour of the oil filling box, and the tolerance fit relationship between the oil filling box and the limiting hole is a transition fit.

[0010] By adopting the above technical solution, the installation position of the oil filling box along the cigarette cartridge is limited by the limiting hole, so that the oil filling box can be stably matched with the cigarette cartridge. At the same time, because the tolerance matching relationship between the oil filling box and the limiting hole is a transition fit, it is convenient to take the oil filling box out along the limiting hole, or to install the oil filling box in the limiting hole.

[0011] Preferably, the oil filling box and the cigarette cartridge are magnetically coupled.

[0012] By adopting the above technical solution, the oil filling box and the cigarette cartridge are magnetically matched, and the magnetic force is used to achieve stable matching between the oil filling box and the cigarette cartridge, thereby reducing the probability of the oil filling box falling off along the cigarette cartridge.

[0013] Preferably, a puncture needle is provided at the abutment point between the limiting hole and the end surface of the oil filling box, and the puncture needle is used to puncture the oil filling box.

[0014] By adopting the above technical solution, after the oil filling box is inserted into the cigarette cartridge along the limiting hole, the oil filling box is punctured by the puncture needle, so that the cigarette oil in the oil filling box can flow smoothly into the cigarette cartridge.

[0015] Preferably, an oil absorber is provided in the cigarette cartridge, and when the puncture needle punctures the oil filling box, the oil absorber is used to absorb the tobacco oil in the oil filling box into the cigarette cartridge.

[0016] By adopting the above technical solution, the oil in the oil filling box is quickly sucked into the cigarette cartridge along the oil filling box through the suction provided by the oil suction component, thereby reducing the probability of the oil in the oil filling box being unable to flow smoothly into the cigarette cartridge due to the air pressure in the oil filling box and the cigarette cartridge being in a balanced state.

[0017] Preferably, a convex ring is provided on the outer side wall of the oil filling box, and a clamping groove is provided on the hole wall of the limiting hole. When the end face of the oil filling box abuts against the limiting hole, the convex ring is located in the clamping groove.

[0018] By adopting the above technical solution, the cooperation between the convex ring and the clamping groove is conducive to improving the stability of the cooperation between the oil filling box and the cigarette cartridge, and reducing the probability of the oil filling box being affected by external force after being punctured by the puncture needle, causing the oil filling box to fall off along the limiting hole.

[0019] Preferably, a silicone ring is provided at the abutment point between the limiting hole and the end surface of the oil filling box.

[0020] By adopting the above technical solution, the silicone ring is helpful to increase the sealing ability of the oil filling box and the cigarette cartridge, and reduce the probability of the smoke oil in the oil filling box and / or the smoke oil in the cigarette cartridge flowing out along the gap between the oil filling box and the cigarette cartridge.

[0021] Preferably, a snap ring is provided at one end of the oil filling box away from the end abutting against the puncture needle, and the snap ring is used for allowing the smoker to take out the oil filling box along the limiting hole.

[0022] By adopting the above technical solution, when the smoker needs to replace the oil filling box, he can use his hands to pull the clamping ring, so that the oil filling box can be taken out along the limiting hole, which is easy to operate.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses an electronic atomizer that is easy to fill with oil. Figure 1-Figure 3 An electronic atomizer that is easy to fill with oil includes a shell 1, a cigarette cartridge 2, and an atomizer assembly 4. The cigarette cartridge 2 is fixedly connected to the shell 1, and the atomizer assembly 4 is arranged in the shell 1. The atomizer assembly 4 is used to atomize the smoke oil in the cigarette cartridge 2. The cigarette cartridge 2 is provided with an inhalation nozzle 3, and the inhalation nozzle 3 is used for the smoker to inhale the atomized smoke oil. The cigarette cartridge 2 is detachably provided with an oil filling box 5, and the oil filling box 5 is used to store the smoke oil. When the oil filling box 5 is set on the cigarette cartridge 2, the smoke oil in the oil filling box 5 will flow into the cigarette cartridge 2.

[0033] Specifically, the atomization assembly 4 includes an atomization part, a power supply and a control module. The atomization part and the control module are powered by the power supply, so that when the smoke oil in the cigarette cartridge 2 flows along the oil outlet to the atomization part, the atomization part can atomize the smoke oil in time, and the smoker can adjust the working state of the atomization part through the control module to meet different smoking needs. It is a conventional smoke oil atomization assembly 4 of the electronic atomizer, and its specific composition and working principle are not described here.

[0034] Therefore, when the oil in the cigarette cartridge 2 is used up, the user can disassemble the oil filling box 5 along the cigarette cartridge 2 and replace it with a new oil filling box 5 without replacing the entire cigarette cartridge 2, which plays a positive guiding role in improving the convenience of oil filling of the electronic atomizer; at the same time, compared with the electronic atomizers on the market that integrate the atomization part on the cigarette cartridge 2, the electronic atomizer of the present application does not need to replace the cigarette cartridge 2, which is conducive to maximizing the utilization rate of the atomization part. It is only necessary to mass-produce the oil filling box 5 and the cigarette cartridges 2 compatible with the oil filling box 5, which also plays a positive guiding role in reducing the production cost of the electronic atomizer.

[0035] The implementation principle of the electronic atomizer that is easy to fill with oil in the embodiment of the present application is: the oil in the cigarette cartridge 2 is atomized by the atomization component 4. Since the cigarette cartridge 2 is fixedly connected to the shell 1 and the cigarette cartridge 2 is provided with an inhalation nozzle 3, the user can inhale the oil atomized by the atomization component 4 through the inhalation nozzle 3. At the same time, a removable oil filling box 5 is provided on the cigarette cartridge 2. When the oil in the cigarette cartridge 2 is used up, the oil filling box 5 is disassembled along the cigarette cartridge 2 and replaced with a new one. The operation is simple and there is no need to replace the entire cigarette cartridge 2, which plays a positive guiding role in improving the convenience of filling the electronic atomizer with oil.

[0036] Reference Figure 2 and Figure 3 A limiting hole 6 is provided on the cigarette cartridge 2 , the contour of the limiting hole 6 matches the contour of the oil filling box 5 , and the tolerance matching relationship between the oil filling box 5 and the limiting hole 6 is a transition fit.

[0037] Specifically, the limiting hole 6 is formed by the side wall of the cigarette cartridge 2 being recessed toward the interior of the cigarette cartridge 2 (for example, the cigarette cartridge 2 is integrally formed by injection molding).

[0038] Furthermore, it should be noted that the interior of the oil filling box 5 is hollow, forming a chamber for storing e-liquid, and the external contour of the oil filling box 5 can be changed according to design requirements, and its specific shape is not described here.

[0039] Therefore, the installation position of the oil filling box 5 along the cigarette cartridge 2 is limited by the limiting hole 6, so that the oil filling box 5 can be stably matched with the cigarette cartridge 2. At the same time, because the tolerance matching relationship between the oil filling box 5 and the limiting hole 6 is a transition fit, it is convenient to take the oil filling box 5 out along the limiting hole 6, or to install the oil filling box 5 in the limiting hole 6.

[0040] Correspondingly, the oil filling box 5 is magnetically coupled to the cigarette cartridge 2. A magnetic ring 7 is installed at the bottom of the limiting hole 6, and a metal ring that magnetically cooperates with the magnetic ring 7 is installed on the end surface of the oil filling box 5 that abuts the bottom of the limiting hole 6. When the oil filling box 5 is inserted into the cigarette cartridge 2 along the limiting hole 6, the metal ring can abut against the magnetic ring 7, and the magnetic force provided by the magnetic ring 7 attracts the metal ring, so that the oil filling box 5 can be stably installed in the limiting hole 6, reducing the probability of the oil filling box 5 falling off along the limiting hole 6.

[0041] At the same time, a convex ring 10 is provided on the outer wall of the oil filling box 5, and a snap-fit ​​groove 11 is provided on the wall of the limiting hole 6. When the end face of the oil filling box 5 abuts the limiting hole 6, the convex ring 10 is located in the snap-fit ​​groove 11. The convex ring 10 is formed by a circumferential protrusion on the outer wall of the oil filling box 5, and the snap-fit ​​groove 11 is formed by a circumferential depression on the inner wall of the limiting hole 6. The shape of the snap-fit ​​groove 11 is adapted to the shape of the convex ring 10. When the smoker inserts the oil filling box 5 into the limiting hole 6, when the convex ring 10 and the snap-fit ​​groove 11 are snap-fitted, it means that the end face of the oil filling box 5 facing the bottom of the limiting hole 6 can just abut against the limiting hole 6, further reducing the probability of the oil filling box 5 falling off along the limiting hole 6 when the electronic atomizer is subjected to external force, thereby improving the stability of the oil filling box 5 when it is installed on the cigarette cartridge 2.

[0042] On the other hand, a silicone ring 12 is provided at the abutment point between the limiting hole 6 and the end face of the oil filling box 5. When the oil filling box 5 is located in the limiting hole 6, the end face of the oil filling box 5 facing the bottom of the limiting hole 6 can abut against the silicone ring 12. The silicone material has the characteristics of being soft and easy to deform, and the gap between the oil filling box 5 and the limiting hole 6 is filled to reduce (or avoid) the amount of oil in the cigarette cartridge 2 and / or the oil filling box 5 flowing out along the gap.

[0043] Reference Figure 2 and Figure 3 A puncture needle 8 is provided at the abutment point between the limiting hole 6 and the end surface of the oil filling box 5 , and the puncture needle 8 is used to puncture the oil filling box 5 .

[0044] Specifically, the puncture needle 8 can be made of metal material, or the puncture needle 8 and the cigarette cartridge 2 can be integrally formed by injection molding. When the oil filling box 5 moves along the limiting hole 6 toward the bottom of the limiting hole 6, the puncture needle 8 punctures the sealing film of the oil filling box 5 (after the oil filling box 5 is filled with cigarette oil, the oil filling box 5 will be sealed by a sealing device, such as aluminum foil or plastic film, to prevent the cigarette oil in the oil filling box 5 from leaking out), thereby opening the sealing film to facilitate the cigarette oil in the oil filling box 5 to flow into the cigarette cartridge 2.

[0045] Furthermore, the smoke cartridge 2 is provided with an oil absorbing member 9. After the puncture needle 8 punctures the oil filling box 5, the oil absorbing member 9 is used to draw the smoke liquid in the oil filling box 5 into the smoke cartridge 2. The oil absorbing member 9 may be a low-density oil-absorbing cotton pad, which has a weak adsorption capacity but can still provide a certain liquid adsorption capacity. The suction provided by the oil absorbing member 9 quickly draws the smoke liquid in the oil filling box 5 along the oil filling box 5 into the smoke cartridge 2, reducing the probability of the smoke liquid in the oil filling box 5 being unable to flow smoothly into the smoke cartridge 2 due to the balanced air pressure in the oil filling box 5 and the smoke cartridge 2.

[0046] Reference Figure 1 and Figure 3The end of the oil filling box 5 away from the puncture needle 8 is provided with a snap ring 13, which is used for the smoker to remove the oil filling box 5 along the limiting hole 6. When the smoker needs to replace the oil filling box 5, he can use his hand to pull the snap ring 13, so that the oil filling box 5 can be removed along the limiting hole 6, which is easy to operate.

[0047] The above are all 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 based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
