Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette and a child lock control method for an electronic cigarette. Background Art

[0002] For existing electronic cigarettes, their child lock functions are generally achieved through buttons or housing components. In the case of the button method, it is generally unlocked by long pressing or unlocking by pressing the button multiple times. However, due to easy touch, there is still a high probability of being accidentally unlocked or accidentally triggering some functions. The child lock of the housing component method generally first closes the air inlet or the smoke pipe through a lock ring, and opens the air inlet or the smoke pipe by rotating the lock ring of the housing component. Since the circuit is not disconnected in this way, on the one hand, there may be a risk of dry burning, presenting certain safety hazards. On the other hand, if the air inlet or the smoke pipe is not opened and suction is directly carried out, it is possible to directly suck out the atomized liquid in the liquid storage chamber, which will cause liquid leakage and the atomized liquid directly entering the human mouth will also cause some health problems. Summary of the Invention

[0003] In view of the above situation, it is necessary to propose an electronic cigarette with high safety and a child lock control method for an electronic cigarette.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: an electronic cigarette, comprising:

[0005] A cartridge assembly, the cartridge assembly includes a liquid storage chamber and an atomization core, and a first magnetic conductive member is provided at the bottom of the cartridge assembly, and the atomization core is electrically connected to the first magnetic conductive member;

[0006] A cigarette rod assembly, provided with an insertion cavity, and a second magnetic conductive member is provided in the insertion cavity. The cartridge assembly is rotatably inserted and connected to the cigarette rod assembly through the insertion cavity. The insertion cavity is a circular hole cavity, and the part of the cartridge assembly cooperating with the insertion cavity is in a cylindrical shape adapted to the circular hole cavity. The first magnetic conductive member and the second magnetic conductive member are magnetically connected.

[0007] The control circuit component is configured inside the cigarette rod component. The control circuit component includes a power management module, an MCU processing module, a child lock output module, a comparator, a timer, and an indicator light. The child lock output module is electrically connected to the second magnetic conductive member. The MCU processing module is electrically connected to the power management module, the child lock output module, the comparator, the timer, and the indicator light respectively. The child lock output module is preset with a connection threshold. When the first magnetic conductive member and the second magnetic conductive member are in electrical contact within a preset time threshold through plugging or rotation and the number of electrical contact times reaches the connection threshold, the comparator transmits a connection signal to the MCU processing module, causing the child lock output module to switch from the child lock off state to the connected state. The child lock output module allows the working current to be output to the atomizing core, and the indicator light emits connection information.

[0008] Further, it further includes an airflow sensing module. The airflow sensing module is electrically connected to the MCU control module. When the airflow sensing module senses the passing of airflow, it sends a working signal to the MCU processor. When the child lock output module is in the connected state, it outputs the working current to the atomizing core.

[0009] Further, the child lock output module includes a PWM switch.

[0010] Further, the power management module, the MCU processing module, the child lock output module, the comparator, and the timer are integrated to form a control circuit board.

[0011] Further, the cigarette rod component includes a housing and a partition board. The partition board divides the housing into a cartridge insertion cavity and an installation cavity. The cartridge insertion cavity is adapted to the cigarette cartridge component. The control circuit component is configured in the installation cavity. The installation cavity has an air inlet communicating with the outside. The second magnetic conductive member is configured on the partition board, and the partition board has an airway hole.

[0012] Further, the cigarette cartridge component further includes a liquid storage chamber, a smoke tube, a mouthpiece, and a base. The first magnetic conductive member is embedded in the base. The mouthpiece is connected to the liquid storage chamber. The smoke tube penetrates through the liquid storage chamber and is connected to the mouthpiece in communication. The atomizing core is configured in the smoke tube and communicates with the liquid storage space in the liquid storage chamber.

[0013] Further, the mouthpiece and the liquid storage chamber are connected in a stepped manner, and the stepped surface of the mouthpiece and the liquid storage chamber abuts against the end surface of the cigarette rod component.

[0014] The present invention also provides a child lock control method for an electronic cigarette, including the above-mentioned electronic cigarette.

[0015] Further, it further includes the following method:

[0016] A preset time threshold and a connection threshold;

[0017] Use a comparator to determine whether the number of connections between the first magnetic conductive member and the second magnetic conductive member reaches the connection threshold within the preset time threshold;

[0018] If so, enable the child lock output module to allow the circuit to be connected, the indicator light emits a connection message, and allow the child lock output module to output a working current to the atomization core.

[0019] Furthermore, if not, keep the child lock output module disconnected.

[0020] The beneficial effects of the present invention are as follows: By inserting or rotating the cartridge assembly, the atomization core forms a circuit or is disconnected from the control circuit assembly. By setting the connection threshold, that is, the number of times of forming a circuit, if the connection threshold is reached within the preset time, the product is unlocked, that is, the child lock output module allows a working current to be output to the atomization core, so that it can be used normally. This method has high safety. Not only a connection threshold is set, but also a time threshold is set. It must reach the connection threshold within the time threshold to be unlocked, and it will not be unlocked due to accidental touch of the switch, nor will it cause liquid leakage due to blocking the air inlet hole; moreover, the cooperation of the first magnetic conductive member and the second magnetic conductive member makes the connection between the cartridge assembly and the rod assembly stable, and it is also convenient for the cartridge assembly to rotate. Based on the circular appearance of the new cartridge-changing electronic cigarette, by single-rotating the cartridge, or rotating the cartridge left and right, or plugging and unplugging, the unlocking state / starting state of the product or the realization of other additional functions can be achieved. The present invention adopts a circular shell structure, and the child lock in the form of components realizes the unlocking of the product by rotating / plugging the circular cartridge assembly. Since the circuit and the control chip are not disconnected, the appearance of the product is more beautiful. On the basis of not changing the original appearance of the product, the use method of unlocking the electronic cigarette by rotating the cartridge is implied, and it is more difficult for minors, especially children, to unlock the product easily. On the other hand, this use method and unlocking method can add more product locking functions, such as misoperation, locking for 10 minutes - 30 minutes and other intelligent control functions. The child lock function of the electronic cigarette product is perfectly realized. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further describes in detail an electronic cigarette and a child lock control method for an electronic cigarette according to the present invention with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] Please refer to Figures 1 - 7 , an electronic cigarette, comprising:

[0037] A cartridge assembly 100, the cartridge assembly 100 includes a liquid chamber 110 and an atomization core 120. A first magnetic conductive member 141 is provided at the bottom of the cartridge assembly 100, and the atomization core 120 is electrically connected to the first magnetic conductive member 141;

[0038] The cigarette rod assembly 200 is provided with an ammunition insertion cavity 220. A second magnetic attraction and conductive member 241 is arranged in the ammunition insertion cavity 220. The cigarette cartridge assembly 100 is rotatably and pluggably connected to the cigarette rod assembly 200 through the ammunition insertion cavity 220. The ammunition insertion cavity 220 is a round hole cavity. The part of the cigarette cartridge assembly 100 that cooperates with the ammunition insertion cavity 220 is in a cylindrical shape adapted to the round hole cavity. The first magnetic attraction and conductive member 141 and the second magnetic attraction and conductive member 241 are magnetically connected.

[0039] The control circuit assembly is arranged in the cigarette rod assembly 200. The control circuit assembly includes a power management module 320, an MCU processing module 400, a child lock output module 500, a comparator 600, a timer 700, and an indicator light 800. The child lock output module 500 is electrically connected to the second magnetic attraction and conductive member 241. The MCU processing module 400 is electrically connected to the power management module 320, the child lock output module 500, the comparator 600, the timer 700, and the indicator light 800 respectively. The child lock output module 500 is preset with a connection threshold. When the first magnetic attraction and conductive member 141 and the second magnetic attraction and conductive member 241 are in electrical contact within a preset time threshold through plugging or rotation for a number of times reaching the connection threshold, the comparator 600 transmits a connection signal to the MCU processing module 400, causing the child lock output module 500 to switch from the child lock off state to the connected state. The child lock output module 500 allows a working current to be output to the atomization core 120, and the indicator light 800 emits a connection message.

[0040] By plugging or rotating the cigarette cartridge assembly 100, the atomization core 120 forms a circuit or is disconnected from the control circuit assembly. By setting the connection threshold, that is, the number of times of forming a circuit, if the connection threshold is reached within a preset time, the product starts to unlock, that is, the child lock output module 500 allows a working current to be output to the atomization core 120, so that it can be used normally. This method has high safety. Not only a connection threshold is set, but also a time threshold is set. It must reach the connection threshold within the time threshold to unlock, and it will not be unlocked due to accidental touch of the switch, nor will it cause liquid leakage due to blocking the air inlet hole 230. Moreover, the cooperation of the first magnetic attraction and conductive member 141 and the second magnetic attraction and conductive member 241 makes the connection between the cigarette cartridge assembly 100 and the cigarette rod assembly 200 stable, and it also facilitates the rotation of the cigarette cartridge assembly 100. Based on the prototype of the novel cartridge-changing electronic cigarette with a round appearance, the unlocking state / starting state / or other additional functions of the product can be realized by single-rotating the cigarette cartridge, or rotating the cigarette cartridge left and right, or plugging and unplugging.

[0041] It can be understood that the connection threshold is greater than 1, that is, at least 2 or more, preferably 3, that is, rotate two and a half circles in one direction, rotate three and a half circles left and right, or plug and unplug 3 times to achieve unlocking. Simply, if the time threshold is set to 3 minutes and the connection threshold is set to 3 times, that is, within 3 minutes after the first contact between the first magnetic attraction and conductive member 141 and the second magnetic attraction and conductive member 241, contact twice more to unlock the product.

[0042] Please refer to Figure 4 , further including an air flow sensing module 900, which is electrically connected to the MCU control module. When the air flow sensing module 900 senses the passing of air flow, it sends a working signal to the MCU processor. When the child lock output module 500 is in a connected state, it outputs a working current to the atomizing core 120. The air flow sensing module 900 generally includes a microphone for sensing air flow, replacing the traditional switch. That is, when the child lock output module 500 is in the unlocked mode (connected state), when the air flow sensing module 900 senses the passing of air flow, the MCU processor enables the child lock output module 500 to output a working current to the atomizing core 120, and the atomizing core 120 generates heat to atomize the atomizing liquid in contact with it. Simply, a traditional switch button can also be used to replace the air flow sensing module 900.

[0043] Specifically, the child lock output module 500 includes a PWM switch. That is, the mode is switched through the PWM switch, generally including a disconnection mode and an unlocking mode. In the disconnection mode, the circuit is completely disconnected, waiting for the first magnetic conductive member 141 and the second magnetic conductive member 241 to contact again. When the preset connection threshold is reached within the predetermined time threshold, the unlocking mode is switched, and the indicator light 800 generally does not display at this time; in the unlocking mode, the child lock output module 500 allows the output of a working current to the atomizing core 120. When the air flow sensing module 900 senses the air flow or the switch button is activated, a working current is output to the atomizing core 120, and the atomizing core 120 atomizes, and the indicator light 800 emits a connection signal, generally a color light. Specifically, a restriction mode can also be set as needed. The restriction mode is between the disconnection mode and the unlocking mode. That is, when the child lock is in the disconnection mode, the first magnetic conductive member 141 and the second magnetic conductive member 241 contact again, triggering the restriction mode, and being in a state of waiting for the unlocking mode to be turned on. The indicator light 800 emits an unlocking information (flashing, or emitting other lights such as a yellow light).

[0044] Preferably, the power management module 320, the MCU processing module 400, the child lock output module 500, the comparator 600, and the timer 700 are integrated to form a control circuit board. Integrating to form a control circuit board is convenient for installation.

[0045] Please refer to Figures 1 - 3, the cartridge rod assembly 200 includes a housing 210 and a partition plate 240. The partition plate 240 divides the housing 210 into a cartridge insertion cavity 220 and an installation cavity. The cartridge insertion cavity 220 is adapted to the cartridge assembly 100. The control circuit assembly is disposed in the installation cavity. The installation cavity has an air inlet hole 230 communicating with the outside. The second magnetic conductive member 241 is disposed on the partition plate 240, and the partition plate 240 has an airway hole 242. It can be understood that the cartridge insertion cavity 220 of the cartridge rod assembly 200 is a round hole, and the outer contour of the liquid storage chamber 110 of the cartridge assembly 100 that cooperates with the cartridge insertion cavity 220 is cylindrical, so as to facilitate rotation. It can be understood that the mouthpiece 130, the smoke pipe 150, the airway hole 242, and the air inlet hole 230 communicate to form an airway. The installation cavity can be configured with a battery 310 as needed. The battery 310 is electrically connected to the power management module 320. Generally, a charging interface 320 can also be configured as needed.

[0046] Please refer to Figures 1 - 3 , the cartridge assembly 100 further includes a liquid storage chamber 110, a smoke pipe 150, a mouthpiece 130, and a base 140. The first magnetic conductive member 141 is embedded in the base 140. The mouthpiece 130 is connected to the liquid storage chamber 110. The smoke pipe 150 penetrates through the liquid storage chamber 110 and communicates with the mouthpiece 130. The atomization core 120 is disposed in the smoke pipe 150 and communicates with the liquid storage space in the liquid storage chamber 110. In particular, the mouthpiece 130 and the liquid storage chamber 110 are integrally formed. It can be understood that the top and the peripheral wall of the liquid storage chamber 110 can be integrally formed or hermetically detachably connected. When the mouthpiece 130 and the liquid storage chamber 110 are integrally formed, the top and the peripheral wall of the liquid storage chamber 110 are integrally formed. The base 140 is generally configured with a liquid injection hole as needed, so as to facilitate liquid injection. The liquid injection hole generally adopts a normally closed liquid injection hole, and liquid injection is performed through a syringe. A liquid injection plug can also be configured as needed. The top of the smoke pipe 150 is generally detachably and hermetically connected to the top of the liquid storage chamber 110, so as to facilitate the installation of the atomization core 120.

[0047] Please refer to Figures 1 - 3 , the mouthpiece 130 and the liquid storage chamber 110 are connected in a stepped manner, and the stepped surface of the mouthpiece 130 and the liquid storage chamber 110 abuts against the end surface of the cartridge rod assembly 200. The stepped surface prevents the cartridge assembly 100 from excessively squeezing the second magnetic conductive member 241.

[0048] It can be understood that the first magnetic conductive member 141 and the second magnetic conductive member 241 can be made of a magnetic and conductive material, or can be made of a magnetic material internally and a conductive material externally, that is, a material with excellent conductivity such as copper, silver, or gold is electroplated on the magnetic material.

[0049] It can be understood that generally two first magnetic conductive members 141 are provided, which are the first pole and the second pole respectively, corresponding to the first pin and the second pin of the atomization core 120, that is, the first pin is electrically connected to the first pole, and the second pin is electrically connected to the second pole; similarly, two second magnetic conductive members 241 are correspondingly provided. The first pole and the second pole are generally powered by a circuit that does not require positive and negative poles to be distinguished, so as to facilitate the 360-degree arbitrary rotation of the cartridge assembly 100.

[0050] Generally, the MCU controller uses a single-chip microcomputer, preferably the NY8B062D single-chip microcomputer.

[0051] Please refer to Figures 1 - 7 , the present invention also provides a child lock control method for an electronic cigarette, including the above-mentioned electronic cigarette.

[0052] Furthermore, the following methods are also included:

[0053] Preset a time threshold and a connection threshold;

[0054] The comparator 600 is used to judge whether the number of connections between the first magnetic conductive member 141 and the second magnetic conductive member 241 reaches the connection threshold within the preset time threshold;

[0055] If so, the child lock output module 500 allows the circuit to be connected, the indicator light 800 emits a connection message, and the child lock output module 500 is allowed to output a working current to the atomization core 120.

[0056] Furthermore, if not, the child lock output module 500 remains disconnected.

[0057] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0058] In addition, if there are descriptions such as "first" and "second" in the embodiments of the present invention, the descriptions of "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0059] In summary, the present invention provides an electronic cigarette and a child lock control method for an electronic cigarette. By plugging or rotating the cartridge assembly, the atomizer core and the control circuit assembly form a loop or disconnect. By setting the connection threshold, that is, the number of times the loop is formed, if the connection threshold is reached within a preset time, the product starts to unlock, that is, the child lock output module allows the output of the working current to the atomizer core, so that it can be used normally. This method is highly safe. Not only is the connection threshold set, but also the time threshold is set. The connection threshold must be reached within the time threshold to unlock. It will not be unlocked due to accidental touch of the switch, nor will it cause leakage due to the closure of the air inlet hole; and the cooperation of the first magnetic conductive part and the second magnetic conductive part makes the connection between the cartridge assembly and the cigarette rod assembly stable, and also facilitates the rotation of the cartridge assembly. Relying on the circular appearance of the new cartridge-changing electronic cigarette as a prototype, the unlocking state / starting state / or other incidental functions of the product can be controlled by rotating the cartridge alone, rotating the cartridge left and right, or plugging and unplugging.

[0060] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
