Referring to FIG1 , an embodiment of the present invention provides a child lock electronic cigarette, comprising an outer tube 100, a spacer layer 101, an air pressure control module 105, a heating device 107 and a battery core 109. The spacer layer 101 is connected to the inner wall of the outer tube 100, and the spacer layer 101 is used to divide the interior of the outer tube 100 into a first cavity 103 and a second cavity 106. The first cavity 103 is connected to the atmospheric pressure through the first airway 102 and the third airway 104, respectively, and the second cavity 106 is connected to the atmospheric pressure through the second airway 108. The heating device 107 is used to generate heat to heat the corresponding medium to form an aerosol; the air pressure control module 105 is connected to the heating device 107 and to the spacing layer 101, and controls the heating device 107 to generate heat when an air pressure difference is formed between the first cavity 103 and the second cavity 106, and also determines whether the air pressure difference meets a preset condition, and locks or unlocks the heating device 107 when the preset condition is met; the battery cell 109 is connected to the heating device 107 through the air pressure control module 105, is located inside the outer tube, and is used for energy supply.

In this embodiment, the child lock electronic cigarette is provided with a locked state and an unlocked state. By setting an air pressure control module between the first cavity and the second cavity to obtain the air pressure difference between the two cavities, when it is judged that the air pressure difference meets the preset condition, the heating device is controlled to lock or unlock the electronic cigarette. Therefore, the user can control the working state of the electronic cigarette by controlling the air pressure difference between the two cavities to meet the preset condition, effectively preventing minors from accidentally taking the electronic cigarette.

In one embodiment, as shown in FIG. 2 , the second cavity 106 is always connected to the atmospheric pressure through the second airway 108, and the first cavity 103 is connected to the atmospheric pressure through the third airway 104, and is also connected to the atmospheric pressure through the first airway 102. Among them, the first airway 102 is the absorption port, and the third airway 104 is the air inlet. When the user smokes the electronic cigarette, the external airflow flows from the third airway 104 through the first cavity 103, and then flows through the first airway 102 to the mouth of the smoker, so at this time the air pressure of the first cavity 103 will be lower than the atmospheric pressure of the second cavity 106. The air pressure control module 105 can sense the air pressure change between the two cavities to produce an air pressure difference and the air pressure of the first cavity 103 is less than that of the second cavity 106, and then control the heating device 107 to generate heat to generate aerosol for the user to smoke. When the electronic cigarette needs to be locked, in this embodiment, the preset value of the air pressure difference between the two cavities can be set to be greater than or equal to 2000PA. It can be set according to the actual use, but the preset value of the air pressure difference needs to be distinguished from the air pressure difference generated by the user's normal electronic cigarette smoking. Generally, the preset value of the air pressure difference is larger. At this time, the preset condition for locking can be set to, when the air pressure control module 105 detects that the air pressure of the second cavity 106 minus the first cavity 103 is greater than or equal to 2000PA three times within 2 seconds, the heating device 107 is locked and no longer generates heat. At this time, even if the air pressure control module 105 can detect that the air pressure of the first cavity 103 is less than the air pressure difference generated by the second cavity 106, it does not control the heating device 107 to generate heat. Similarly, if the heating device 107 of the current electronic cigarette is locked, the air pressure control module 105 detects the air pressure difference generated by the user's puffing action. If the air pressure of the second cavity 106 minus the air pressure of the first cavity 103 is greater than or equal to 2000PA three times within 2 seconds, the heating device 107 is unlocked. At this time, the electronic cigarette can generate aerosol for the user to inhale through normal puffing action. That is, by detecting the user's puffing action, the above-mentioned child lock electronic cigarette is locked or unlocked. The above example is only one way to realize the child lock function. Different inhalation times and time intervals can be set according to actual needs, and different preset conditions can also be set according to actual needs.

In another embodiment, referring to FIG. 3 , the electronic cigarette can also be locked or unlocked by blowing. When the user blows air from the first air channel 102 , the external airflow flows from the first air channel 102 through the first cavity 103 , and then flows through the third air channel 104 to the outside. At this time, the air pressure of the third air channel 104 will be higher than the atmospheric pressure, that is, the air pressure of the first cavity 103 is higher than the air pressure of the second cavity 106 . When the air pressure control module 105 detects that the air pressure of the first cavity 103 is greater than that of the second cavity 106 and the air pressure difference between the two cavities is greater than a preset value, (in this embodiment, the air pressure difference between the two cavities is set to be greater than or equal to 100PA, which can be set as needed in actual use, but should be distinguished from the air pressure difference generated by the user's normal electronic cigarette smoking, and the difference calculation method of the two is different), and the air pressure difference lasts for a period of time (which can be a period greater than or equal to 1 second, which can be set as needed), the preset condition for locking at this time is when the air pressure of the first cavity 103 is greater than that of the second cavity 106 and the air pressure difference is greater than or equal to 100PA for 3 times within 2 seconds, then the air pressure control module 105 locks the heating device 107 and no longer generates heat; the same is true for unlocking, that is, when the first air pressure difference between the first cavity 102 and the second cavity 106 is greater than or equal to 100PA for 3 times within 2 seconds, then the air pressure control module 105 unlocks the heating device 107 to achieve the unlocking operation of the electronic cigarette. The working state of the heating device 107 is equivalent to the working state of the electronic cigarette, that is, when the heating device 107 is in a locked state, the electronic cigarette is also in a locked state, and when the heating device 107 is in an unlocked state, the electronic cigarette is also in an unlocked state. When the electronic cigarette is in a locked state, even if there is an air pressure difference between the first cavity 103 and the second cavity 106, the heating device 107 will not work. The above example is only one way to realize the child lock function. Different blowing intervals can be set according to actual needs, and different preset conditions can be set according to actual needs for locking and unlocking the above air pressure difference.

Through the above two embodiments, two operations are performed at the same time: first, the third airway 104 is sealed by hand while blowing or inhaling in the first airway 102; second, the air pressure difference between the two cavities meets the preset conditions. Through these two operations, the heating device 107 of the electronic cigarette can be locked or unlocked, thereby controlling the operation of the electronic cigarette. The user can control the operation of the electronic cigarette by controlling the air pressure difference between the two cavities, effectively preventing minors from accidentally taking the electronic cigarette.

In one embodiment, as shown in FIG4 , the air pressure control module 105 includes an air pressure sensing module 406 and a control module 407. The air pressure sensing module 406 is used to generate a first control signal according to the air pressure difference formed when the air pressure of the first cavity 103 is less than the air pressure difference formed with the second cavity 106 when the user smokes the electronic cigarette, and to generate a second control signal when the air pressure difference between the first cavity 103 and the second cavity 106 meets the preset conditions of the aforementioned blowing or inhaling locking and unlocking. The control module 407 is connected to the air pressure sensing module 406 and the heating device 107, controls the heating device 107 to generate heat according to the first control signal, and locks or unlocks the heating device 107 according to the second control signal. The first and second control signals are in parallel, and this embodiment does not exclude the situation where the two signals exist at the same time, but the control module 407 will only respond to the first control signal to control the heating device 107 when the heating device 107 is unlocked.

In this embodiment, the air pressure sensing module 406 can accurately sense the air pressure difference between the first cavity 103 and the second cavity 106 and generate a control signal so that the control module 407 controls the heating device 107 according to the control signal. Through the above connection relationship, the air pressure difference between the two cavities can be accurately and effectively sensed, and the air pressure difference is converted into a control signal so that the control module 407 controls the heating device, which can improve the accuracy of the sensed voltage difference and improve the coordination between the modules.

In one embodiment, referring to Figure 4 again, the air pressure sensing module 406 includes an airflow sensor 401, a detection module 405 and a capacitance value reading module 402, wherein the airflow sensor 401 is used to detect the air pressure difference between the first cavity 103 and the second cavity 106, and generate a capacitance change value corresponding to the air pressure difference; the capacitance value reading module 402 is connected to the airflow sensor 401, and is used to read the capacitance change value generated by the airflow sensor 401 and convert it into a numerical output; the detection module 405 is connected to the capacitance value reading module 402, generates a first control signal according to the capacitance change value, and generates a second control signal when it is judged through the capacitance change value that the air pressure difference between the first cavity 103 and the second cavity 106 meets the preset conditions for the aforementioned blowing or inhalation locking and unlocking.

In this embodiment, the airflow sensor 401 includes but is not limited to a capacitive microphone and a micro-electromechanical system microphone. The airflow sensor 401 can accurately detect the air pressure difference between the first cavity 103 and the second cavity 106, and generate a capacitance change value based on the air pressure difference. The capacitance value reading module 402 reads the capacitance change value and converts it into a processable numerical output, and the detection module 405 judges and generates a control signal based on the processed numerical value, thereby enhancing the stability of the conversion processing between the signals.

In one embodiment, referring to FIG. 4 again, the control module 407 further includes a controllable switch 404, which is electrically connected to the heating device 107 (i.e., the controllable switch 404 is connected to the heating device 107 through the battery cell 109), and is opened or closed in response to the second control signal. When the controllable switch 404 is closed, the energy supply of the battery cell 109 and the heating device 107 is connected. At this time, the control module 407 can control the heating device 107 to heat in response to the first control signal, corresponding to the unlocked state of the heating device 107; when the controllable switch 404 is disconnected, the heating device 107 cannot obtain energy from the battery cell 109, and then the control module 405 cannot control the heating device 107 to heat in response to the first control signal, corresponding to the locked state of the heating device 107.

The controllable switch 404 includes but is not limited to a field effect transistor, a thyristor, a relay, and a triode.

In one embodiment, referring to FIG. 4 again, the child lock electronic cigarette further includes: an indicator light 403 , connected to the air pressure control module 105 , located on the outer wall of the outer tube 100 , for indicating the working status of the entire child lock electronic cigarette.

Among them, the form of the indicator light 403 is not limited, and it can be an LED indicator light, or any other device that can achieve the indication function, and the LED lights can be set in multiples as needed; for example, an LED can be set to be always on to indicate that the controllable switch in the heating device is in a closed state, and the LED can be always closed to indicate that the controllable switch in the heating device is in an open state. Another LED is set to light up in a preset time period to indicate that the heating element is heating, and the LED light is off in a preset time period to indicate that the heating element is not heating. It should be noted that when some indicator lights include multiple small LED lights and the lighting and extinguishing of the LED lights contain multiple circuit structures, a part of the LED lights can be set to indicate the state of the controllable switch, and another part can be set to indicate whether the heating element is heating or not heating. This embodiment does not limit the structure of the indicator light 403.

In this embodiment, the indicator light 403 is arranged on the outer wall of the outer tube 100, so that the user can clearly understand the working status of the child lock electronic cigarette when using the electronic cigarette, which is convenient for use.

In one embodiment, as shown in FIG. 6 , the outer tube 100 of the electronic cigarette includes a first end, and the electronic cigarette further includes: an upper sealing plug 601 ; a mouthpiece 602 , including two ends, one end of which is connected to the upper sealing plug 601 , and the other end is connected to the first end of the outer tube 100 .
