Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic cigarette with an anti-condensation air passage. Background Technology
[0002] Currently, in existing e-cigarettes, the air intake vents used to provide atomized airflow to the atomizer coil are all located at the very bottom of the atomizer. The air passages used to guide airflow to activate the microphone control board to power the atomizer coil are also located at the bottom of the atomizer and connected to the air intake vents. When the vapor produced by the heating element heating the e-liquid inside the atomizer coil is discharged through the atomization passages, some of the vapor liquefies to form condensate. Under the influence of gravity, this condensate flows back within the atomization passages and then flows out of the atomizer through the air intake vents, causing leakage. Furthermore, the condensate flowing out of the atomizer can also flow into the air passages and drip onto the microphone, causing microphone malfunction or mis-activating the power board to control the atomizer coil.

[0024] It should be noted that the specification of this application contains a large number of technical features distributed across various technical solutions. Listing all possible combinations of technical features (i.e., technical solutions) would make the specification overly lengthy. To avoid this problem, the various technical features of the utility model in the above-described utility model content, the various technical features of the utility model in the various embodiments and examples below, and the various technical features of the utility model in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible.

[0025] In this utility model, the terms "upper", "lower", "top", "bottom", "inner", "outer", "side", etc. are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing and understanding the technology of this utility model, and are not intended to limit the device or component to have a specific orientation or to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] like Figure 1-5As shown, this utility model provides an electronic cigarette with an anti-condensation airflow channel, including a main unit 13 and an atomizer 1 electrically connected to the main unit 13. The atomizer 1 has an oil storage chamber 101 for storing e-liquid, an atomizing core 102 disposed in the oil storage chamber 101 for atomizing the e-liquid, and an air vent 120 for providing atomizing airflow to the atomizing core 102. The atomizer 1 has an air tube 103 vertically inserted into the air vent 120, and the main unit 13 has an air inlet 10 communicating with the air vent 120. 01. The main unit 13 has a sealing body 401 that abuts against the bottom end of the air tube 103 to block the bottom end of the air tube 103, an air sensor 1301 corresponding to the sealing body 401, and a power supply assembly 1302 that is electrically connected to the atomizing core 102. The sealing body 401 has an air guide channel 402 that communicates with the air tube 103 and the air sensor 1301. The air sensor 1301 has a microphone 8 that is used to activate the power supply assembly 1302 to supply power to the atomizing core 102 after sensing changes in airflow. It should be noted that by designing the ventilation channel 104 and ventilation space 105 of the ventilation section 120, which provides atomizing airflow to the atomizing core 102, into an L-shape that is connected horizontally and vertically, and by vertically inserting an air tube 103 that communicates with the air guide channel 402 to guide air to the air sensor 1301 into the ventilation space 105, the condensate produced by the atomizing e-liquid of the atomizing core 102 will only be stored in the ventilation space 105 after entering the ventilation space 105 due to the isolation of the air tube 103. Therefore, it will not flow out of the atomizer 1 through the air tube 103 and the ventilation section 120, causing leakage, nor will it enter the air sensor 1301 from the air guide channel 402, causing the microphone 8 to be falsely activated or malfunction.
[0027] In some embodiments, the air sensor 1301 is formed by an air groove and / or an air passage 602. In this embodiment, the air sensor 1301 is formed by an air groove and an air passage 602. The air groove is used to allow airflow and to accommodate the microphone 8, and the air passage 602 is used to allow airflow into the air groove to activate the microphone 8.
[0028] In some embodiments, the ventilation section 120 includes a ventilation channel 104 and a ventilation space 105, which are isolated from the oil storage chamber 101. The ventilation channel 104 is longitudinally arranged in the atomizer 1, and the ventilation space 105 is transversely arranged in the atomizer 1, with the ventilation channel 104 and the ventilation space 105 communicating end-to-end. The ventilation channel 104 and the ventilation space 105, arranged longitudinally and transversely in the atomizer 1 and communicating end-to-end, allow the ventilation section 120 to form an L-shape. When the condensate generated by the atomizing coil 102 atomizes the e-liquid enters the ventilation space 105, it will not flow out through the ventilation channel 104 from the air inlet 1001, preventing leakage.
[0029] In some embodiments, the atomizer 1 has a through hole 106 at its bottom end that corresponds to and communicates with the ventilation space 105. The air tube 103 is vertically inserted into the ventilation space 105 through the through hole 106, so that the ventilation space 105 communicates with the air tube 103. The side wall of the atomizer 1 has an opening 107 that communicates with the air inlet 1001 and the upper end of the ventilation channel 104. The air inlet 1001 communicates with the ventilation channel 104 through the opening 107. The through hole 106 is used for the vertical insertion of the air tube 103 into the ventilation space 105. The air tube 103 is used to isolate the condensate entering the ventilation space 105 and also to connect the ventilation space 105 and the air channel 402, so that the airflow can enter the air sensor 1301 to activate the microphone 8. The opening 107 is used to connect the air inlet 1001 and the ventilation channel 104.
[0030] In some embodiments, the lower end of the atomizing core 102 extends out of the oil storage chamber 101, the lower end of the atomizing core 102 corresponds to the ventilation space 105 and is offset from the air tube 103, the atomizing core 102 has an atomizing channel 108 communicating with the ventilation space 105, a heating core 109 is provided in the atomizing channel 108, and an oil inlet hole 110 corresponding to the heating core 109 is opened on the outer wall of the atomizing core 102. The lower end of the atomizing core 102 is misaligned with the air tube 103 to prevent the condensate generated in the atomizing channel 108 of the atomizing core 102 from dripping onto the top of the air tube 103 and then flowing out of the atomizer 1 through the air tube 103, which would cause leakage in the atomizer 1. It would also enter the air sensor 1301 through the air guide channel 402, causing the microphone 8 to be falsely activated or malfunction. The atomizing channel 108 is used for airflow and smoke exhaust. The heating core 109 is used to heat the oil storage chamber 101 to produce smoke. The oil inlet 110 is used to guide the e-liquid in the oil storage chamber 101 into the heating core 109.

The top end of the support 6 is provided with a first conductive post 2 abutting against the first contact 111 and a second conductive post 3 abutting against the second contact 112. The housing 10 is used to accommodate the support 6 and the atomizer 1. The support 6 is used to install the first conductive post 2 and the second conductive post 3, and also to support and limit the atomizer 1, preventing the atomizer 1 from being excessively inserted into the housing 10. The first contact 111 and the second contact 112 are used for conductive connection to the heating element 109, and the first conductive post 2 and the second conductive post 3 are used for conductive connection to the atomizer 1.
[0032] In some embodiments, the atomizer 1 has a connecting tube 113 at its top end, the lower end of the connecting tube 113 extends into the oil storage chamber 101, a connecting channel 114 is formed inside the connecting tube 113, the upper end of the atomizing core 102 extends into the lower end of the connecting tube 113, so that the atomizing channel 108 communicates with the connecting channel 114, a mouthpiece 115 is inserted into the upper end of the connecting tube 113, and a smoking channel 116 communicating with the connecting channel 114 is opened in the mouthpiece 115. The atomizing channel 108 communicates with the smoking channel 116 through the connecting channel 114. The connecting tube 113 is used to connect the upper end of the atomizing core 102 and the lower end of the mouthpiece 115. The connecting channel 114 is used to connect the atomizing channel 108 and the smoking channel 116. The mouthpiece 115 is used to hold the mouth in the mouth to smoke. When smoking, the external airflow can enter through the air inlet 1001, and then enter the ventilation channel 104 and the ventilation space 105 through the opening 107. Then it enters the atomizing channel 108 through the ventilation space 105, and finally drives the heating core 109 to enter the smoke generated by the e-liquid. The smoke enters the user's mouth through the smoking channel 116 via the connecting channel 114 and is inhaled.
[0033] In some embodiments, the power supply assembly 1302 includes a battery cell 9 and a power board 7. The battery cell 9 is disposed in a bracket 6, and the power board 7 is disposed on the bracket 6. The battery cell 9 is electrically connected to the power board 7, and the power board 7 is electrically connected to the first conductive post 2 and the second conductive post 3. The power board 7 is provided with a button 701 and a socket 702. The housing 10 is provided with a button 11 that abuts against the button 701. The bottom end of the housing 10 is provided with a base 12, and the base 12 is provided with a socket 1201 corresponding to the socket 702. The battery cell 9 is used to supply power to the power board 7 to enable its electronic control function. The power board 7 connects to the first conductive post 2 via the first contact 111 and to the second conductive post 3 via the second contact 112 to supply power to the heating element 109 so that it heats up. The base 12 is used to seal the bottom of the outer shell 10. The button 11 is located outside the outer shell 10. Pressing the button 701 will activate the power board 7 to supply power. The charging device can be inserted into the socket 702 through the socket 1201 to charge the battery cell 9 via the power board 7.
[0034] In some embodiments, the top of the bracket 6 is further provided with a first magnet 5, and the bottom of the atomizer 1 is further provided with a second magnet 117 corresponding to the first magnet 5. The atomizer 1 is detachably attached to the upper end of the outer casing 10 by the attraction between the first magnet 5 and the second magnet 117. The top of the atomizer 1 is provided with an oil filling hole 118 communicating with the oil storage chamber 101. The top of the atomizer 1 is detachably provided with an oil plug 119 for sealing the oil filling hole 118. The first magnet 5 and the second magnet 117 are both neodymium iron boron magnets. Their strong magnetism makes the connection between the atomizer 1 and the main unit 13 more stable. Their high hardness makes them less likely to break under heavy pressure and impact. After the oil plug 119 is removed from the top of the atomizer 1, oil can be injected into the oil storage chamber 101 through the oil filling hole 118.
[0035] In some embodiments, the top of the bracket 6 is also provided with an air guide 4. The upper end of the air guide 4 is narrowed to form a sealing body 401 that abuts against the bottom end of the air tube 103.

The air guide channel 402 extends from the top of the sealing body 401 into the first air groove 402, so that the two ends of the air guide channel 402 are respectively connected to the air tube 103 and the first air groove 402. The top of the bracket 6 is also provided with a second air groove 601. The microphone 8 is disposed in the second air groove 601. The power board 7 is also electrically connected to the microphone 8. The bottom wall of the second air groove 601 is provided with an air passage 602 that communicates with the first air groove 402. The first air groove 402, the second air groove 601, and the air passage 602 constitute the air sensor 1301. The air guide 4 and the sealing body 401 are both made of silicone. The sealing body 401 abuts against the bottom of the air tube 103 to prevent air leakage when the airflow enters the air guide channel 402 from the air tube 103, and to prevent liquid or dust from entering the air guide channel 402. By designing the first air groove 402 and the second air groove 601 and connecting them through the air passage 602, the airflow sensitivity is strong, and the microphone 8 can be more sensitive in the second air groove 601. The power board 7 is also used to power the microphone 8 to enable the function of powering the power board 7 to control the airflow sensing.

The upper end of the air channel 402 communicates with the air tube 103 to connect the air tube 103 and the first air groove 402.
[0040] like Figure 6 As shown in the specific embodiment of this utility model, the airflow direction during the use of the electronic cigarette is specifically described. When smoking through the mouthpiece 115, the external airflow can enter through the air inlet 1001, and then enter the ventilation channel 104 and the ventilation space 105 through the opening 107. In the ventilation space 105, part of the airflow will enter the first air groove 402 through the air tube 103 from the air guide channel 402, and then enter the second air groove 601 through the air passage 602. After the microphone 8 senses the change in airflow in the second air groove 601, it will activate the power board 7 to power the heating core 109 to make it heat up. At the same time, another part of the airflow in the ventilation space 105 will enter the atomization channel 108, and then drive the heating core 109 to heat the smoke generated by the e-liquid. The smoke is then inhaled through the smoking channel 116 through the connecting channel 114.
[0041] like Figure 7 As shown in the specific embodiment of this utility model, the condensate generated in the smoking channel 116 and atomization channel 108 after the electronic cigarette is used is specifically described. After smoking, the smoke will liquefy and generate condensate when it passes through the atomization channel 108 and smoking channel 116. Under the action of gravity, the condensate will flow back into the ventilation space 105 through the atomization channel 108. Since the air tube 103 is vertically inserted into the ventilation space 105, the condensate will be isolated in the ventilation space 105 by the air tube 103. Therefore, it will not flow out of the atomizer 1 through the air tube 103, the ventilation channel 104 and the opening 107, causing leakage. It will also not enter the first air slot 402 through the air guide channel 402 through the air passage 602 and then enter the second air slot 601 through the air passage 602, causing the microphone 8 to mistakenly activate the power board 7 to power the heating core 109, or cause the microphone 8 to malfunction.
[0042] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
