Description

Technical Field

[0001] The invention relates to the field of atomizers, and in particular to an electronic cigarette atomizer with a protective function. Background Art

[0002] The atomizer is an important component of the electronic cigarette. It mainly evaporates the e-liquid by heating to produce an atomization effect for smokers to inhale and get the smoking experience. Therefore, smokers will use e-cigarettes to quit traditional smoking, reduce their dependence on traditional cigarettes, and reduce the harm of traditional cigarettes to smokers' bodies.

[0003] However, compared to traditional cigarettes, e-cigarettes use e-liquid, and the solvent in the e-liquid is affected by the environment and becomes viscous. The viscosity of the e-liquid directly affects the atomization of the e-liquid, which in turn affects the smoking experience. When the e-cigarette is not used for a long time and there is still e-liquid in the atomizer, the oil-absorbing cotton in the atomizer will easily transfer the e-liquid from the oil storage chamber to the position of the heating wire. If the heating wire fails to atomize the e-liquid in time, the oil-absorbing cotton will absorb too much e-liquid and leak, causing the e-liquid to corrode related components in the atomizer and clog the atomizer, resulting in the e-liquid being sucked into the mouth, resulting in a poor smoking experience. Summary of the invention

[0023] A positioning block made of silicone material is provided at the lower part of the screw rod 9 to prevent the movable disk 4 from being separated from the screw rod 9 due to excessive rotation.

[0024] The outer surface of the movable disk 4 is provided with a plurality of anti-skid grooves for increasing the friction between the user's hand and the movable disk 4 , so as to facilitate the user to rotate the movable disk 4 .

[0025] Each limiting block 12 is provided with an arcuate surface 1202 at one end away from the wedge surface 1201, which is used to temporarily store the smoke oil that penetrates from the oil storage cavity along the oil absorption cotton 7 when the limiting block 12 clamps the oil absorption cotton 7 to interrupt the transmission of the smoke oil from the oil storage cavity to the heater Ⅰ8.

[0026] It also includes a heater II 101; the portion of the oil-absorbing cotton 7 located in the isolation cabin 11 is surrounded by two symmetrically arranged heaters II 101; and the heater I8 is electrically connected to all the heaters II 101.

[0027] The heater II 101 is located near the lowest point of the arc surface 1202 and is used to preheat the overflowed smoke oil when the infiltrated smoke oil overflows onto the arc surface 1202 after the limit block 12 clamps the oil-absorbing cotton 7.

[0028] It also includes hook claws 102 ; a plurality of hook claws 102 are arranged on one side of each limit block 12 close to the oil-absorbing cotton 7 ; and all the hook claws 102 are connected to the oil-absorbing cotton 7 .

[0029] The working steps of the above embodiment are: Before using the atomizer, the user first manually unscrews the mouthpiece 2 from the housing 1, and then pours the oil into the annular oil storage chamber. This is the top filling method. When the volume of the oil filled reaches three-quarters of the volume of the oil storage chamber, the filling is stopped. Then the user screws the mouthpiece 2 onto the housing 1 and places the atomizer vertically upward. After the bubbles in the oil are fully overflowed and the oil-absorbing cotton 7 in the oil removal chamber fully absorbs the oil, the oil diffuses to the oil-absorbing cotton 7 wound by the heater Ⅰ 8. The smoke oil on the oil-absorbing cotton 7 starts to atomize, and the user can inhale the smoke generated by the atomization core 5 through the cigarette holder 2 to get a feeling similar to that of real smoking.

[0030] During normal use, the user will not use the atomizer for a long time to inhale smoke, and will put down the atomizer and the cigarette holder at this time. When the atomizer is not used for a long time, the oil-absorbing cotton 7 continues to absorb the smoke oil, so that the oil-absorbing cotton 7 is swollen. When the atomizer is needed again, the heater Ⅰ8 does not fully atomize the smoke oil on the swollen oil-absorbing cotton 7. Considering that after the oil-absorbing cotton 7 is full of smoke oil, the smoke oil is not atomized and discharged in time, and the oil-absorbing cotton 7 at the atomizer core 5 will leak smoke oil, which will not only waste the smoke oil, but also corrode the electronic components in the atomizer and the cigarette holder. Therefore, after the user finishes using the atomizer each time, he only needs to pull the atomizer out of the cigarette holder, and then the user manually grabs the movable disk 4 and rotates the movable disk 4. Figure 4 As shown, when viewed from top to bottom, the movable disk 4 rotates clockwise, and the upper part of the screw rod 9 is fixedly connected to the two hook rods 10, and the hook rod 10 is slidably connected to the atomizer core 5, and the hook rod 10 can only slide up and down. Therefore, when the movable disk 4 is rotated, the screw rod 9 moves downward, thereby driving the hook rod 10 to move downward, and the pointed cone on the upper part of the hook rod 10 drives the corresponding limit block 12 to slide along the isolation cabin 11 in the direction away from each other, and the clamping block 1001 slides downward in the corresponding clamping groove 1203, so the limit block 12 begins to squeeze the oil-absorbing cotton 7. After the limit block 12 clamps the oil-absorbing cotton 7, the supply of smoke oil from the oil storage chamber to the heater Ⅰ8 is interrupted, and then the atomizer is inserted back into the cigarette rod, thereby avoiding the leakage of smoke oil, resulting in waste of smoke oil, and corrosion of the heater Ⅰ8 and related electronic components.

[0031] After the limit block 12 clamps the oil-absorbing cotton 7, the oil storage cavity will also make the oil-absorbing cotton 7 located in the isolation cabin 11 absorb the smoke oil, so an arc surface 1202 is provided on the limit block 12. After the limit block 12 clamps the oil-absorbing cotton 7, two adjacent arc surfaces 1202 form a bowl shape, such as Figure 5As shown, the leaked smoke oil can be temporarily stored. Then, considering that after the electronic cigarette is exposed to the air, the solvent evaporates, making the smoke oil gradually become viscous, and the ambient temperature also affects the viscosity of the smoke oil. The lower the temperature, the greater the viscosity of the smoke oil. Therefore, the temporarily stored smoke oil is easy to become viscous, and the corresponding limit blocks 12 stick together and are not easy to separate, and the oil-absorbing cotton 7 is not easy to restore to its original state, which affects the user's use of the atomizer to smoke again. The oil storage chamber is insufficient to supply the smoke oil at the heater I 8 through the oil-absorbing cotton 7, so a heater II 101 is set at the arc surface 1202. When using it again, it is only necessary to pull the atomizer out of the cigarette rod again, and then the user rotates the movable disk 4 counterclockwise to drive the screw 9 to move upward, and synchronously makes the hook rod 10 return to its original state. The hook rod 10 moves upward, synchronously driving the card block 1001 to move upward in the card slot 1203, and the card block 1001 pulls back and resets the limit block 12. At the same time, the hook claw 102 on the limit block 12 also pulls open the flattened oil-absorbing cotton 7, making the oil-absorbing cotton 7 fluffy, which is convenient for the oil-absorbing cotton 7 to absorb the tobacco oil, and then allows the tobacco oil to flow into the area of ​​the heater I 8. When the user presses the start button, the heater II 101 located at the bottom of the bowl-shaped arcuate surface 1202 heats up and starts to preheat the retained tobacco oil, reducing the viscosity of the tobacco oil. The tobacco oil can be absorbed by the oil-absorbing cotton 7 and then diffused to the position of the heater I 8, thereby reducing the waste of tobacco oil and the corrosion of related electronic components caused by the leakage of tobacco oil.

[0032] Second embodiment On the basis of the first embodiment, according to Figure 2-Figure 4 As shown, it also includes a blocking ring 201; a plurality of straight slide grooves 5001 are opened on the upper part of the atomizer core 5; the atomizer core 5 is detachably connected to the blocking ring 201; a plurality of protrusions are arranged on the blocking ring 201, and each protrusion is slidably matched with a straight slide groove 5001.

[0033] The inner ring of the retaining ring 201 is provided with a flange extending downwards, which is used to block the flow of smoke oil toward the central hole of the retaining ring 201.

[0034] The working steps of the above embodiment are: On the basis of the above embodiment, it should also be considered that when the atomizer is not used for a long time, the atomizer is generally placed horizontally. In combination with the position where the smoke oil seeps out to the arc surface 1202 in the above embodiment, the smoke oil gradually increases at the arc surface 1202, and then the seeped smoke oil flows to the side wall of the atomizer core 5. At this time, if the user grabs the atomizer and installs it on the cigarette rod to smoke, the user absorbs the smoke oil mist from the atomizer core 5 through the cigarette holder 2 and the conduit 6. It is very easy to suck out the smoke oil that seeps into the side wall of the atomizer core 5. Even if filter cotton is provided at the mouthpiece 2, the smoke oil sucked out will easily block the mesh of the filter cotton when passing through the filter cotton, causing the user to feel strenuous and have a poor experience when inhaling the smoke oil mist, and the filter cotton has to be replaced regularly, which is time-consuming and laborious. Therefore, a detachable retaining ring 201 is installed on the upper part of the atomizer core 5, so that the smoke oil leaking out of the atomizer core 5 will not flow out of the atomizer core 5 in any placement state.

[0035] Finally, considering that many parts are integrated in the atomizer core 5, the shell 1 and the fixing seat 3 are set to be detachable, and the atomizer core 5 and the conduit 6 are set to be detachable. Therefore, when the atomizer needs to be maintained, the various detachable parts can be removed with the help of professional maintenance personnel, and then the parts that need to be cleaned and replaced can be processed. For example, the atomizer core 5 is prone to accumulate smoke oil. After removing the conduit 6, the retaining ring 201 can be taken out along the straight groove 5001, and then the atomizer core 5 and the retaining ring 201 can be cleaned. Then, only the corresponding parts need to be reset and can be reused, which greatly reduces the difficulty of maintenance, thereby reducing the failure rate of the atomizer when in use and greatly improving the user experience.
