Description

Technical Field

[0001] The present invention relates to the technical field of simulated smoking, and in particular to an electronic cigarette. Background Art

[0002] E-cigarettes are electronic products with lower health impacts than traditional cigarettes. They effectively reduce the harmful effects of traditional cigarettes and offer the same smoke experience as cigarettes. They heat and atomize e-liquid, turning it into vapor for users to inhale, making them a relatively healthy product.

[0003] An electronic cigarette generally includes an oil storage cartridge, an atomizer core, and a main unit. The oil in existing oil storage cartridges is primarily in liquid form. Liquid oil is fluid, and during actual use, the oil flows directly onto the atomizer core for heating. However, the presence of liquid oil has the following disadvantages: when the seal is weak or when the device is shaken frequently, the oil can easily leak out of the cartridge housing. A small portion of the oil in existing oil storage cartridges is adsorbed on block foam, which is then composited with a heating element. This form has the disadvantages of low heating efficiency, insufficient heating, and more complex production and manufacturing. Summary of the Invention

[0004] The purpose of the present invention is to provide an electronic cigarette, aiming to solve the problems of easy leakage of existing liquid tobacco oil, low heating efficiency of tobacco oil adsorbed on block foam, and complicated production and manufacturing of the block foam and heating element.

[0005] To solve the above technical problems, the present invention is implemented as follows: an electronic cigarette comprises an oil storage cartridge, an atomizer core and a main body that are assembled and connected in sequence, the oil storage cartridge comprising a cartridge shell and oil storage cotton adsorbed with oil, the cartridge shell being provided with a through oil storage cotton mounting cavity, the oil storage cotton being mounted in the oil storage cotton mounting cavity and the oil storage cotton being provided with a through core hole, the core hole being connected to the openings at both ends of the oil storage cotton mounting cavity; the atomizer core comprising an atomizer core shell and a heating element, the atomizer core shell being provided with a heating element mounting cavity, the heating element being mounted in the heating element mounting cavity and an assembly gap being formed between the columnar side surface of the heating element and the cavity wall of the heating element mounting cavity, the cartridge shell being assembled in the assembly gap, the heating element being adapted to be embedded in the core hole, the columnar side surface of the heating element being in contact with the hole wall surface of the core hole; the main body comprising a main body shell and a power supply mounted on the main body shell, the atomizer core shell and the main body shell being assembled and connected, the power supply being electrically connected to the heating element to enable the heating element to generate heat.

[0006] Furthermore, the length of the heating element is smaller than the length of the core hole, and the cigarette cartridge housing is assembled in the assembly gap so that the heating element fits into the core hole.

[0007] Furthermore, the cigarette cartridge housing is assembled in the assembly gap and the heating element is adapted to be embedded in the middle position of the core hole.

[0008] Furthermore, the heating element and the core hole are both columnar structures.

[0009] Furthermore, the oil storage cartridge also includes two fixing plugs respectively embedded in the openings at both ends of the oil storage cotton installation cavity. The oil storage cotton is clamped between the two fixing plugs and thus installed in the oil storage cotton installation cavity. Both of the fixing plugs are provided with plug holes that pass through and are connected to the core hole. The plug hole relatively close to the heating element can allow the heating element to pass through.

[0010] Furthermore, the oil storage cartridge further includes a filter tip, which is installed in a plug hole relatively far away from the heating element, and a channel communicating with the core hole is opened on the filter tip.

[0011] Furthermore, the heating element includes a ceramic core and a heating wire. The ceramic core is a column and has a through heating wire mounting hole. The heating wire is installed in the heating wire mounting hole and the electrode pin of the heating wire extends from the end of the ceramic core. The atomizer core shell and the host shell are assembled and connected, and the power supply is electrically connected to the electrode pin extending from the end of the ceramic core.

[0012] Furthermore, the heating element further includes an input electrode, one end of the input electrode is electrically connected to the electrode pin, and the other end of the input electrode is electrically connected to the power supply.

[0013] Furthermore, the atomizer core further includes an inner sleeve, which is fixedly arranged in the heating element installation cavity, and one end of the inner sleeve is adapted to be inserted into the heating wire installation hole.

[0014] Furthermore, the atomizer core also includes a fixing ring and a connecting terminal. The heating element mounting cavity has openings at both ends. The fixing ring is embedded in the opening of the heating element mounting cavity close to the main unit shell. The connecting terminal is fixedly arranged on the fixing ring. Both the fixing ring and the connecting terminal are provided with through holes for the input electrode to pass through. One end of the inner sleeve is adapted to be inserted into the heating wire mounting hole, and the other end of the inner sleeve is fixedly arranged on the connecting terminal.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention adsorbs the smoke oil on the oil storage cotton, and a core hole is opened on the oil storage cotton. The heating element is embedded in the core hole so that the smoke oil on the oil storage cotton can be slowly adsorbed onto the heating element. The host then controls the heating element to generate heat to heat the smoke oil. The electronic cigarette with this structure not only has good sealing and the smoke oil is not easy to leak; but also the heating element and the oil storage cotton are in contact with each other through the columnar side and are not compounded together, so the heating effect is good and the production and manufacturing are relatively simple.

[0030] like Figure 1-Figure 3As shown, an electronic cigarette 100 provided in this embodiment includes an oil storage cartridge 10, an atomizer core 20 and a host 30 that are assembled and connected in sequence. The oil storage cartridge 10 includes a cartridge shell 11 and an oil storage cotton 12 adsorbed with oil. A through oil storage cotton mounting cavity 111 is provided on the cartridge shell 11. The oil storage cotton 12 is installed in the oil storage cotton mounting cavity 111 and a through core hole 121 is provided on the oil storage cotton 12. The core hole 121 is connected to the openings at both ends of the oil storage cotton mounting cavity 111; the atomizer core 20 includes an atomizer core shell 21 and a heating element 22. The atomizer core shell 21 is provided with a heating element 22. The main unit 30 includes a main unit housing 31 and a power supply 32 mounted on the main unit housing 31. When the atomizer core housing 21 and the main unit housing 31 are assembled and connected, the power supply 32 is electrically connected to the heating element 22 to generate heat. In this embodiment, the heating element 22 and the core hole 121 are both columnar structures.

[0031] In this embodiment, the oil storage cotton 12 is foam, which is allowed to absorb a certain amount of tobacco oil before being installed in the oil storage cotton installation cavity 111. The tobacco oil is absorbed on the foam and stored in an osmotic manner, preventing the tobacco oil from flowing and leaking out of the cigarette cartridge housing.

[0032] In this embodiment, the e-liquid is arranged in the form of being adsorbed on the oil storage cotton, so that the e-liquid in the same liquid state no longer has fluidity and is stored stably. During actual use, the heating element is inserted into the core hole to heat the e-liquid. Compared with the traditional e-liquid arrangement method, this e-liquid arrangement method has the advantages of good storage stability and is not easy to leak.

[0033] In this embodiment, an outer cover 40 is further provided between the cartridge housing 11 , the atomizer core housing 21 and the main body housing 31 . The provision of the outer cover 40 can better fix the three together and enhance the sealing performance.

[0034] In this embodiment, the power source 32 is a battery, but in other embodiments, the power source may also be other conventional power devices, which will not be described in detail here.

[0035] In this embodiment, the length of the heating element 22 is less than the length of the core hole 121. When the cigarette cartridge housing 11 is assembled in the assembly gap 212, the heating element 22 is adapted to be embedded in the core hole 121. Preferably, when the cigarette cartridge housing 11 is assembled in the assembly gap 212, the heating element 22 is adapted to be embedded in the middle position of the core hole 121. In this embodiment, the heating element 22 is adapted to be embedded in the middle position of the core hole 121. During actual operation, the ceramic core 221 gradually absorbs the tobacco oil from the oil storage cotton 12 onto the ceramic core 221, and the adsorption effect is good.

[0036] In this embodiment, the heating element 22 and the core hole 121 are both columnar structures. The heating element 22 and the core hole 121 are both columnar structures and cooperate with each other to greatly increase the contact area between the two, enhance the adsorption effect, and speed up the work efficiency.

[0037] like Figure 3 、 Figure 4 and Figure 5 As shown, the oil storage smoke cartridge 10 also includes two fixing plugs respectively embedded in the two end openings of the oil storage cotton mounting cavity 111 (these two fixing plugs are respectively a first fixing plug 13 and a second fixing plug 14, the first fixing plug 13 is embedded in the upper end opening of the oil storage cotton mounting cavity 111, and the second fixing plug 14 is embedded in the lower end opening of the oil storage cotton mounting cavity 111). The oil storage cotton 12 is clamped between the first fixing plug 13 and the second fixing plug 14 and thus installed in the oil storage cotton mounting cavity 111. The first fixing plug 13 and the second fixing plug 14 are both provided with plug holes that pass through and are connected to the core hole 121, and the plug holes relatively close to the heating element 22 can allow the heating element 22 to pass through.

[0038] like Figure 4 and Figure 5 As shown, the oil storage cartridge 10 also includes a filter 15, which is installed in the plug hole relatively far away from the heating element 22, and has a channel 151 connected to the core hole 121. The filter is a filter cotton, and the filter is set to filter the water vapor generated when the oil is heated.

[0039] like Figure 6 and Figure 7 As shown, the heating element 22 includes a ceramic core 221 and a heating wire 222. The ceramic core 221 is a column and a through heating wire mounting hole 2211 is opened on the ceramic core 221. The heating wire 222 is installed in the heating wire mounting hole 2211 and the electrode pin of the heating wire 222 extends from the end of the ceramic core 221. When the atomizer core housing 21 and the host housing 31 are assembled and connected, the power supply 32 is electrically connected to the electrode pin extending from the end of the ceramic core 221.

[0040] In this embodiment, the ceramic core has a penetration function, which can slowly absorb the tobacco oil on the oil storage cotton into the ceramic core, and then transfer the tobacco oil to the heating wire through the penetration function of the ceramic core.

[0041] Preferably, the heating element 22 further includes an input electrode 223 , one end of the input electrode 223 is electrically connected to the electrode pin, and the other end of the input electrode 223 is electrically connected to the power source 32 .

[0042] like Figure 6 and Figure 7 As shown, the atomizer core 20 further includes an inner sleeve 23 , which is fixedly disposed in the heating element mounting cavity 211 , and one end of the inner sleeve 23 is adapted to be inserted into the heating wire mounting hole 2211 .

[0043] like Figure 6 and Figure 7 As shown, the atomizer core 20 also includes a fixing ring 24 and a connecting terminal 25. The heating element mounting cavity 211 has openings at both ends. The fixing ring 24 is embedded in the opening of the heating element mounting cavity 211 close to the main body shell 31. The connecting terminal 25 is fixedly set on the fixing ring 24. Both the fixing ring 24 and the connecting terminal 25 are provided with through holes for the input electrode 223 to pass through. One end of the inner sleeve 23 is adapted to be inserted into the heating wire mounting hole 2211, and the other end of the inner sleeve 23 is fixedly set on the connecting terminal 25.

[0044] like Figure 3 As shown, when the electronic cigarette in this embodiment is actually used, the host with a battery is installed together with the atomizer core through the connecting terminal. After the host and the atomizer core are installed together, the battery is electrically connected to the input electrode, and the battery can control the heating wire to heat it; the cigarette cartridge with oil storage cotton is installed together with the upper end of the atomizer core. After the cigarette cartridge and the atomizer core are installed together, the oil storage cotton is put on the ceramic core, and the tobacco oil on the oil storage cotton is transferred to the heating wire through the ceramic core. The battery controls the heating wire to heat the tobacco oil, thereby achieving atomization.

[0045] In this embodiment, the host has a conventional button and LED function indicator. The specific working principle is: press the button five times within two seconds, the LED indicator flashes for five seconds and then goes out, the host is started, and the airflow working mode is entered. Inhale from the atomizer core end, the LED indicator gradually goes out, and a new cartridge begins to be used. After counting 50 times, the LED indicator flashes 10 times, prompting the replacement of the cartridge, and the host is shut down at the same time; the host is in the off state, and a long press for three seconds enters the atomizer core self-cleaning mode. The LED indicator will flash continuously for two minutes. In the cleaning mode, the atomizer core will be heated multiple times, and the user will assist in blowing to clear the smoke generated during the cleaning process of the atomizer core. The host in this embodiment is an advanced multi-functional host, but is not limited to this. In other embodiments, the host can also directly adopt a simple conventional ordinary version of the host, which will not be described in detail here.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
