Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 and 2, fig. 1 and 2 are schematic structural diagrams of two embodiments of an electronic cigarette of the present application, where the electronic cigarette 100 includes: a controller 1, a first air pressure sensor 2 and a second air pressure sensor 3.
The electronic cigarette is an electronic product simulating a cigarette, and has the same appearance, smoke, taste and sensation as the cigarette. It is a product which is absorbed by users after nicotine and the like are changed into steam by means of atomization and the like.
Generally, an electronic cigarette mainly comprises a smoke tube for containing nicotine solution, an evaporation device (namely, an atomizer) and a power supply part. The atomizer is powered by a power supply and can convert liquid nicotine in the cartridge into mist. In the prior art, when the atomizer is started by an electronic airflow sensor (such as a microphone switch), a power circuit works by inhaling air, so as to supply power to the atomizer; there is also a manual sense that requires the user to press a button and then smoke. The electronic airflow sensor mostly adopts an inductive airflow sensor, an electronic cigarette adopting the inductive airflow sensor is convenient to use, but has inconsistent sensitivity and is not easy to control, the consistency of products cannot be guaranteed, and after oil or water vapor is fed, the electronic cigarette is easy to automatically trigger by mistake or does not work, so that the user experience is influenced.
In the present embodiment, the first air pressure sensor 2 and the second air pressure sensor 3 are connected to the controller 1, respectively. The first air pressure sensor 2 is arranged at a position, communicated with the ambient air environment, in the electronic cigarette 100, and is used for detecting a pressure value of first air pressure of the ambient air environment and transmitting the pressure value of the first air pressure to the controller 1; typically in actual product design, the first air pressure sensor 2 is mounted on the PCBA of the e-cigarette and close to the air inlet. The second air pressure sensor 3 is arranged on the air flow channel 4 of the electronic cigarette 100, and is used for detecting a pressure value of second air pressure on the air flow channel 4 and transmitting the pressure value of the second air pressure to the controller 1; typically in actual product design, the second air pressure sensor 3 is mounted on the PCBA of the e-cigarette and is located where the airflow channel 4 flows through. The controller 1 is configured to control the atomizer 5 of the electronic cigarette 100 to start or close according to a pressure difference between the received pressure value of the first air pressure and the received pressure value of the second air pressure.
The Air Pressure Sensor (Air Pressure Sensor) refers to a device or apparatus capable of sensing a gas Pressure signal and converting the gas Pressure signal into a usable output electrical signal according to a certain rule. The first air pressure sensor 2 is configured to detect a pressure value of a first air pressure of the ambient air environment, and therefore, the first air pressure sensor 2 is disposed at a position a in the electronic cigarette 100, where the first air pressure sensor communicates with the ambient air environment. The second air pressure sensor 3 is for detecting a pressure value of the second air pressure on the air flow passage 4, and therefore, the second air pressure sensor 3 is provided on the air flow passage 4. The pressure difference between the pressure value of the first air pressure and the pressure value of the second air pressure is the difference between the pressure value of the first air pressure of the ambient air environment and the pressure value of the second air pressure on the air flow channel 4. In the absence of any externally applied pressure, the pressure value of the first air pressure of the ambient air environment is substantially the same as the pressure value of the second air pressure on the air flow channel 4, the pressure difference being zero; an absolute value of the pressure difference being greater than zero indicates that the pressure value of the first air pressure of the ambient air environment is not equal to the pressure value of the second air pressure on the air flow channel 4. The method comprises the steps of determining a direction for pressure, wherein the pressure flowing to the direction of the suction nozzle is positive, the pressure opposite to the direction of the suction nozzle is negative, when the pressure value of first air pressure of the surrounding air environment is larger than the pressure value of second air pressure on the air flow channel 4, namely the pressure difference is larger than zero, the direction of the pressure difference is the direction flowing to the suction nozzle, judging that a user possibly applies 'sucking' action, and when the pressure value of the first air pressure of the surrounding air environment is smaller than the pressure value of the second air pressure on the air flow channel 4, namely the pressure difference is smaller than zero, the direction of the pressure difference is the direction deviating from the suction nozzle, judging that the user possibly applies 'spitting' action. Accordingly, the controller 1 can control the atomizer 5 of the electronic cigarette 100 to be turned on or off.
In contrast, the comparison of the pressure difference between the pressure of the air pressure at the inlet of the air flow channel 4 and the pressure of the air pressure near the suction nozzle 9 on the air flow channel 4 can accurately indicate whether the user applies an action to the electronic cigarette, and can also accurately determine the action that the user may apply, in one embodiment, to indicate whether the user applies an action to the electronic cigarette more accurately, the first air pressure sensor 2 is disposed at the inlet a1 of the air flow channel 4, and the second air pressure sensor 3 is disposed at the position B of the air flow channel 4 near the suction nozzle 9.
In another embodiment, to more accurately illustrate whether the user's action on the e-cigarette is sufficiently distinct to be sensed around the nebulizer, the first air pressure sensor 2 is disposed at the inlet a1 of the airflow channel 4, and the second air pressure sensor 3 is disposed at the position C of the airflow channel 4 near the top of the nebulizer 5.
The electronic cigarette comprises a controller 1 and a first air pressure sensor 2 and a second air pressure sensor 3 which are respectively connected with the controller 1, wherein the first air pressure sensor 2 is arranged at a position, communicated with the ambient air environment, in the electronic cigarette 100 and used for detecting a pressure value of first air pressure of the ambient air environment and transmitting the pressure value of the first air pressure to the controller 1; the second air pressure sensor 3 is arranged on the air flow channel 4 of the electronic cigarette 100, and is used for detecting a pressure value of second air pressure on the air flow channel 4 and transmitting the pressure value of the second air pressure to the controller 1; the controller 1 is configured to control the atomizer 5 of the electronic cigarette 100 to start or close according to a pressure difference between the received pressure value of the first air pressure and the received pressure value of the second air pressure. Because the controller 1 of the electronic cigarette 100 controls the atomizer 5 of the electronic cigarette 100 to start or close according to the pressure difference between the pressure value of the first air pressure of the ambient air environment and the pressure value of the second air pressure on the air flow channel 4, the detection of the pressure difference can be ensured to be consistent and controllable without being influenced by oil feeding or water vapor, and by means of the mode, the electronic cigarette 100 has good sensitivity consistency and high reliability, and can not cause false triggering or work.
In one embodiment, the controller 1 stores a predetermined pressure difference threshold, and the controller 1 is configured to control the atomizer 5 of the electronic cigarette 100 to be activated when the pressure difference is greater than zero and greater than the predetermined pressure difference threshold, and to control the atomizer 5 of the electronic cigarette 100 not to be activated or closed when the pressure difference is equal to or less than the predetermined pressure difference threshold. Because the detected pressure values of the first air pressure and the second air pressure have errors and the like, in order to further ensure that the atomizer 5 can be really started at a proper time to meet the smoking requirement of a user, a predetermined pressure difference threshold value is preset in the embodiment, the atomizer 5 is started only when the pressure difference is greater than the predetermined pressure difference threshold value, and when the pressure difference is equal to or less than the predetermined pressure difference threshold value, the atomizer 5 of the electronic cigarette 100 is controlled not to be started or closed, so that the atomizer 5 is prevented from being started by mistake due to the detection error of the pressure difference.
The pressure value of the first air pressure is a pressure value of the first air pressure of the ambient air environment detected in real time, and the pressure value of the second air pressure is a pressure value of the second air pressure on the air flow channel detected in real time. Real-time detection allows real-time pressure differentials to be obtained, allowing real-time control of the activation and deactivation of the atomizer 5. That is, further, the controller 1 controls the atomizer 5 of the electronic cigarette 100 to be turned on or off in real time according to the pressure difference detected in real time and the predetermined pressure difference threshold value.
In one embodiment, the output power of the power supply may be adjusted according to the magnitude of the pressure difference, and the amount of smoke may be adjusted. Referring to fig. 3, the electronic cigarette 100 further includes a power control and output circuit 6, the power control and output circuit 6 is connected to the controller 1, after the atomizer 5 is started, the controller 1 determines real-time output power corresponding to the pressure difference according to the pressure difference detected in real time and the corresponding relationship between the pressure difference and the output power stored in the controller 1, and sends a first instruction to the power control and output circuit 6, and the power control and output circuit 6 responds to the first instruction and outputs the real-time output power corresponding to the pressure difference to the atomizer 5, so that the atomizer 5 generates smoke amount corresponding to the real-time output power.
In the present embodiment, the correspondence between the pressure difference and the output power, and the correspondence between the output power and the smoke amount are determined in advance based on empirical values or experimental data. The corresponding real-time output power can be determined according to the pressure difference detected in real time, the controller 1 sends a first instruction to the power control and output circuit 6, the power control and output circuit 6 responds to the first instruction and outputs the real-time output power according to the pressure difference, and therefore the atomizer 5 can generate the smoke amount corresponding to the real-time output power.
For example, it is preset that: when 3-4 pressure difference units are used, 2-3 output power units are corresponded; when 5-6 pressure difference units are used, 4-5 output power units are corresponded; when 7-8 pressure difference units are used, 6-7 output power units are corresponded; 9-10 pressure difference units, corresponding to 8-9 output power units. The pressure difference detected in real time is 4 pressure difference units, and 3 output power units are correspondingly output at the moment; for another example, if the pressure difference detected in real time is 7 pressure difference units, then 6 output power units are correspondingly output at this time; and so on.
Further, in this correspondence, the larger the pressure difference, the larger the output power corresponding to the pressure difference, and the larger the amount of mist generated by the atomizer. Through the mode, the actual smoking requirement of the user can be simulated and met, and therefore the user experience is improved.
In one embodiment, the e-cigarette may also determine whether the action applied by the user is "inhaling" (i.e., drawing a cigarette) or "blowing," which helps to accurately control the opening or closing of the nebulizer. Specifically, the pressure difference is the pressure value of the first air pressure minus the pressure value of the second air pressure, the controller 1 is configured to determine that the air flow direction of the air flow channel 4 is the direction toward the suction nozzle, i.e., "suck" (smoke), to control the atomizer 5 of the electronic cigarette 100 to start when the pressure difference is greater than zero, and determine that the air flow direction of the air flow channel is the direction away from the suction nozzle, i.e., "blow", to control the atomizer 5 of the electronic cigarette 100 not to start or close when the pressure difference is less than zero.
Referring to fig. 4, in an embodiment, the electronic cigarette 100 further includes a battery management circuit 8, the battery management circuit 8 is connected to the controller 1, the controller 1 is further configured to send a second instruction to the battery management circuit 8, and the battery management circuit 8 is configured to manage the power supply 7 of the electronic cigarette 100 in response to the second instruction.
Further, the battery management circuit 8 performs charge management, discharge management, and safety monitoring management on the power supply 7 of the electronic cigarette 100. In one embodiment, the power source 7 is a lithium battery.
