Abstract
Description
Technical Field
[0001] This disclosure relates to the field of electronic cigarette technology, and more particularly to an electronic cigarette with adjustable vapor and intensity levels on opposite sides. Background Technology
[0002] An electronic cigarette is an electronic atomization product that uses an electrically heated atomizing core to heat e-liquid introduced into the core, forming aerosol vapor particles for the user to inhale. It typically includes a housing containing a control board, a battery, an e-liquid reservoir, and an atomizing core. Sometimes the reservoir and core are integrated into the housing, forming a one-piece electronic cigarette; other times, the reservoir and core are separate, forming a replaceable cartridge assembly used with a compatible power source / modifier. Electronic cigarettes usually have a vapor valve structure, allowing users to adjust the airflow to achieve different vapor flavors. This method has some effect on different vapor concentrations, but it's not particularly significant. Another approach is to use adjustment buttons. A long press turns the device on / off, a short press outputs low power, and another short press outputs high power, thus adjusting the concentration of aerosol vapor particles. Button adjustments usually include a display screen showing the adjustment level or LED indicator lights, with different lit pairs indicating different levels. While adjusting the output power at different levels can significantly improve the atomization concentration, this approach increases the cost of components and assembly for the display screen or LED indicator lights. Therefore, the existing technology needs to be optimized and improved to achieve both better performance and lower cost. Utility Model Content
[0003] In view of this, this disclosure proposes an electronic cigarette with adjustable power levels on both sides. The up-and-down movement of the toggle switch can provide feedback on the adjusted power output level, saving the need for a display screen or LED indicator and reducing costs.
[0004] According to one aspect of this disclosure, an electronic cigarette is provided with adjustable vapor pressure and adjustable power levels on opposite sides, including a cartridge and a main unit. The main unit has a insertion cavity, into which the cartridge is inserted and electrically connected to the main unit. The main unit includes a housing, a mounting bracket disposed within the housing, a battery cell disposed on the mounting bracket, and a control board electrically connected to the control board. The mounting bracket has a first slot and a second slot on opposite sides near its upper end. The first slot has an adjustable vapor pressure valve that can be pushed up and down, and the second slot has... It has a gear adjustment key that can be pushed up and down, and a vent is provided on the mounting bracket corresponding to the bottom of the first slot, which leads to the upper end of the mounting bracket; the control board is fixed on the front or back of the mounting bracket, and a toggle switch is provided on the side of the control board near the gear adjustment key. The gear adjustment key is connected to the toggle switch. When the gear adjustment key is pushed up and down, it drives the lever of the toggle switch to move up and down. The toggle switch is used to control the output power of the control board. Through holes are provided on both sides of the housing corresponding to the air regulating valve and the gear adjustment key.
[0005] Furthermore, the toggle switch is a horizontal surface mount single-pole double-throw switch, and the lever of the toggle switch protrudes from the edge of the control board. The gear adjustment key includes a slider body, a lug on one side of the slider body, and a protruding toggle part in the center of the front of the slider body. The lug has a hole for engaging the lever of the toggle switch, and the slider body is embedded in the second slot.
[0006] Furthermore, the slider seat body has a long slot on the edge opposite to the lug. The outer edge of the slider seat body corresponding to the long slot has an outward-protruding arc edge. The long slot provides elasticity for the arc edge. A protrusion is provided on the side wall of the second slot corresponding to the arc edge of the slider seat body. The side wall of the protrusion has three arc recesses. The arc edge of the slider seat body abuts against the arc recesses to limit the movement when pushing up and down.
[0007] Furthermore, the cartridge contains a dual-heating-mesh atomizing core. The bottom of the cartridge has a first power terminal, a second power terminal, and a third power terminal. The dual-heating-mesh atomizing core includes a first heating mesh and a second heating mesh that share a common negative electrode pin, and a first positive electrode pin and a second positive electrode pin that are individually connected to the first heating mesh and the second heating mesh, respectively. The first, second, and third power terminals are arranged in a row from left to right. The first positive electrode pin is connected to the first power terminal, the negative electrode pin is connected to the second power terminal, and the second positive electrode pin is connected to the third power terminal. The upper end of the mounting bracket has a first spring pin, a second spring pin, and a third spring pin that respectively contact and connect to the first, second, and third power terminals. The first, second, and third spring pins are electrically connected to the control board.
[0008] Furthermore, the mounting bracket is provided with a mounting cavity on the other side of the control board. A MEMS airflow sensor is installed in the mounting cavity and is electrically connected to the control board. The bottom of the mounting cavity is provided with a sensor airflow activation channel that connects to the upper end of the mounting bracket.
[0009] Furthermore, a silicone sealing ring is provided on the outer wall of the mounting bracket near its upper end. The silicone sealing ring is an independent component sleeved on the mounting bracket, or the mounting bracket and the silicone sealing ring are integrally molded by secondary injection molding.
[0010] Furthermore, the air regulating valve includes an elongated valve body with at least one air inlet. A protruding push button is provided on the elongated valve body below the air inlet, which pushes the elongated valve body up and down to adjust the size of the air inlet relative to or offset from the through hole position on the side wall of the outer shell, thereby adjusting the air intake volume when the electronic cigarette is in use.
[0011] The beneficial effects of this utility model are as follows: The electronic cigarette designed using this technical solution is primarily a cartridge-type electronic cigarette. This type of electronic cigarette is typically flat and elongated. An airflow valve and a speed adjustment button are respectively located on both sides of the main body of the electronic cigarette, with their positions near the top conforming to the ergonomics of holding the electronic cigarette when in use. The thumb and forefinger can selectively or simultaneously operate the airflow valve and the speed adjustment button. This allows for selective adjustment of the airflow volume or speed level during use, producing more diverse variations in atomization concentration and improving the user experience. Furthermore, the speed adjustment button and the horizontally mounted single-pole double-throw switch on the edge of the control panel serve as a toggle switch. When toggled, the toggle switch lever moves up and down, providing a direct and tactile change in position. This eliminates the need for a display screen or LED indicator light for speed status feedback, saving on display screen or LED indicator light components and reducing assembly steps, thus saving costs.

[0020] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.
[0021] Please refer to the attached diagram in the instruction manual. Figures 1 to 8 This technical solution discloses an electronic cigarette with adjustable airflow and power level on opposite sides. It includes a cartridge 1 and a main unit 2. The main unit 2 has a insertion cavity 201, into which the cartridge 1 is inserted and electrically connected to the main unit 2. The main unit 2 includes a housing 21, a mounting bracket 22 within the housing 21, a battery cell 23 and a control board 24 mounted on the mounting bracket 22, with the battery cell 23 electrically connected to the control board 24. The mounting bracket 22 has a first slot 221 and a second slot 222 on opposite sides near its upper end. The first slot 221 has a vertically movable airflow valve 25, and the second slot 222 has a vertically movable power level adjustment button 26. A ventilation channel 2201 connecting to the upper end of the mounting bracket 22 is provided at the bottom of the first slot 221.
[0022] The control board 24 is fixed to the front or back of the mounting bracket 22. A toggle switch 241 is provided on the side of the control board 24 near the gear adjustment key 26. The gear adjustment key 26 is connected to the toggle switch 241. When the gear adjustment key 26 is pushed up and down, it drives the lever of the toggle switch 241 to move up and down. The toggle switch 241 is used to control the output power of the control board 24. Through holes are provided on both sides of the housing 21 corresponding to the air regulating valve 25 and the gear adjustment key 26.
[0023] In this embodiment, the toggle switch 241 is a horizontal surface-mount single-pole double-throw switch. The lever of the toggle switch 241 protrudes from the edge of the control plate 24. The gear adjustment key 26 includes a slider seat 261, a lug 262 on one side of the slider seat 261, and a protruding actuating part 263 in the center of the front of the slider seat 261. The lug 262 has a hole for engaging the lever of the toggle switch 241. The slider seat 261 is embedded in the second slot 222. By moving the slider seat 261 up and down, the lever of the toggle switch 241 can be moved up and down to adjust the gear. For example, moving it to the top gear turns off the power, moving it to the middle gear outputs low power, and moving it to the bottom gear outputs high power.
[0024] Please refer to Figure 7 , Figure 8 In a preferred embodiment, the slider seat 261 has a long slot 264 on the edge opposite to the lug 262. The outer edge of the slider seat 261 corresponding to the long slot 264 has an outwardly protruding arc-shaped convex edge 265. The long slot 264 provides elasticity for the arc-shaped convex edge 265. A protrusion 2221 is provided on the side wall of the second slot 222 corresponding to the arc-shaped convex edge 265 of the slider seat 261. The side wall of the protrusion 2221 has three arc-shaped recesses 2222. The arc-shaped convex edge 265 of the slider seat 261 abuts against the arc-shaped recesses 2222 to achieve a limit position when pushing up and down. By setting the long slot hole 264 and the arc protrusion 265, a protrusion 2221 and a corresponding arc recess 2222 for limiting the gear position are provided on the side wall of the second slot 222. This achieves a tactile feeling of a gear position limit when the slider seat 261 is pushed, and maintains the assembly stability of the gear adjustment key 26, making it less prone to loosening.
[0025] Preferably, the cartridge 1 contains a dual-heating-mesh atomizing core 10. The bottom of the cartridge 1 has a first power terminal 11, a second power terminal 12, and a third power terminal 13. The dual-heating-mesh atomizing core 10 includes a first heating mesh and a second heating mesh that are connected to a common negative electrode pin, and a first positive electrode pin and a second positive electrode pin that are connected to the first heating mesh and the second heating mesh, respectively. The first power terminal 11, the second power terminal 12, and the third power terminal 13 are arranged in a row from left to right. The first positive electrode pin is connected to the first power terminal 11, the negative electrode pin is connected to the second power terminal 12, and the second positive electrode pin is connected to the third power terminal 13. The upper end of the mounting bracket 22 has a first spring pin 27, a second spring pin 28, and a third spring pin 29 that are respectively in contact with and connected to the first power terminal 11, the second power terminal 12, and the third power terminal 13. The first spring pin 27, the second spring pin 28, and the third spring pin 29 are electrically connected to the control board 24. When the power output is high, the first heating grid and the second heating grid work simultaneously, while when the power output is low, only the first heating grid or the second heating grid works alone.
[0026] In one embodiment, the mounting bracket 22 has a mounting cavity 223 on the opposite side of the control board 24. A MEMS airflow sensor is installed in the mounting cavity 223 and is electrically connected to the control board 24. The bottom of the mounting cavity 223 has a sensor airflow activation channel 2202 that connects to the upper end of the mounting bracket 22.
[0027] Furthermore, a silicone sealing ring 224 is provided on the outer wall of the mounting bracket 22 near its upper end. The silicone sealing ring 224 is an independent component sleeved on the mounting bracket 22, or the mounting bracket 22 and the silicone sealing ring 224 are integrally molded by secondary injection molding.
[0028] Furthermore, the air regulating valve 25 includes an elongated valve body with at least one air inlet on it. A protruding push button is provided on the elongated valve body below the air inlet, which pushes the elongated valve body up and down to adjust the size of the air inlet relative to or offset from the through hole on the side wall of the outer shell 21, thereby adjusting the air intake when the electronic cigarette is in use.
[0029] The electronic cigarette designed in this scheme features a vapor control valve 25 and a power level adjustment button 26 on both sides of the main unit 2. These positions, near the top, conform to the ergonomics of holding the electronic cigarette correctly. The thumb and forefinger can selectively or simultaneously operate the vapor control valve 25 and the power level adjustment button 26. This allows for selective adjustment of the airflow volume or power level, resulting in more diverse vapor concentration variations and enhancing the user experience.
[0030] In this design, the gear adjustment button 26 and the horizontal patch single-pole double-throw switch located on the edge of the control board 24 serve as a toggle switch 241. When the gear adjustment button 26 is toggled, it causes the lever of the toggle switch 241 to move up and down, providing a direct and tactile change in position. This eliminates the need for a display screen or LED indicator light in the electronic cigarette to provide feedback on the gear status, saving on display screen or LED indicator light components and reducing the corresponding assembly steps, thus saving costs.
