Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

Referring to FIG. 1 and FIG. 2 , FIG. 1 and FIG. 2 are structural schematic diagrams of two embodiments of the electronic cigarette of the present application. The electronic cigarette 100 includes: a controller 1 , a first air pressure sensor 2 and a second air pressure sensor 3 .

E-cigarettes are electronic products that mimic cigarettes and have the same look, smoke, taste and feel as cigarettes. It is a product that allows users to inhale after turning nicotine, etc. into steam by means of atomization.

Generally, electronic cigarettes are mainly composed of a smoke pipe containing nicotine solution, an evaporation device (ie atomizer) and a power supply. The atomizer is powered by a power source and can convert the liquid nicotine in the pod into mist. In the prior art, the atomizer is activated by an electronic airflow sensor (such as a microphone switch), and the power circuit will work as soon as the air is inhaled, thereby supplying power to the atomizer; there is also a manual induction that requires the user to press a button, Then smoke. Most electronic airflow sensors use inductive airflow sensors. Electronic cigarettes using this inductive airflow sensor are easy to use, but the sensitivity is inconsistent, difficult to control, and product consistency cannot be guaranteed. affect the user experience.

In the embodiment of the present application, the first air pressure sensor 2 and the second air pressure sensor 3 are respectively connected to the controller 1 . The first air pressure sensor 2 is set at a position in the electronic cigarette 100 that communicates with the surrounding air environment, and is used to detect the pressure value of the first air pressure in the surrounding air environment, and transmit the pressure value of the first air pressure to the controller 1; In product design, the first air pressure sensor 2 is installed on the PCBA of the electronic cigarette and close to the air inlet. The second air pressure sensor 3 is arranged on the airflow channel 4 of the electronic cigarette 100, and is used to detect the pressure value of the second air pressure on the airflow channel 4, and transmit the pressure value of the second air pressure to the controller 1; generally in the actual product design Among them, the second air pressure sensor 3 is installed on the PCBA of the electronic cigarette and is located at the position where the airflow channel 4 flows through. The above-mentioned controller 1 is used to control the start or stop of the atomizer 5 of the electronic cigarette 100 according to the received pressure difference between the pressure value of the first air pressure and the pressure value of the second air pressure.

Air Pressure Sensor refers to a device or device that can sense gas pressure signals and convert the gas pressure signals into usable output electrical signals according to certain rules. The first air pressure sensor 2 is used to detect the pressure value of the first air pressure of the surrounding air environment. Therefore, the first air pressure sensor 2 is arranged at a position A in the electronic cigarette 100 communicating with the surrounding air environment. The second air pressure sensor 3 is used to detect the pressure value of the second air pressure on the air flow channel 4 , therefore, the second air pressure sensor 3 is arranged on the air flow channel 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 surrounding air environment and the pressure value of the second air pressure on the airflow channel 4 . In the absence of any external pressure, the pressure value of the first air pressure in the surrounding air environment is basically the same as the pressure value of the second air pressure on the airflow channel 4, and the pressure difference is zero; when the absolute value of the pressure difference is greater than zero, it indicates The pressure value of the first air pressure of the surrounding air environment is not equal to the pressure value of the second air pressure on the airflow channel 4 . Determine a direction for the pressure, the pressure flowing in the direction of the suction nozzle is positive, and the pressure in the direction away from the suction nozzle is negative, when the pressure value of the first air pressure of the surrounding air environment is greater than the pressure value of the second air pressure on the air flow channel 4, that is When the pressure difference is greater than zero, it indicates that the direction of the pressure difference is the direction of flow to the suction nozzle, and it can be judged that the user may apply the action of "suction". The pressure value, that is, when the pressure difference is less than zero, it indicates that the direction of the pressure difference is away from the suction nozzle, and it can be judged that the user may apply the "spit" action. According to this, the controller 1 can control the atomizer 5 of the electronic cigarette 100 to start or stop.

Relatively speaking, the pressure difference between the pressure of the air pressure at the inlet of the airflow channel 4 and the pressure of the air pressure on the airflow channel 4 close to the suction nozzle 9 can accurately indicate whether the user has applied an action to the electronic cigarette, and can also accurately determine whether the user may apply an action. In one embodiment, in order to more accurately explain whether the user exerts an action on the electronic cigarette, the first air pressure sensor 2 is set at the entrance A1 of the airflow channel 4, and the second air pressure sensor 3 is set at the airflow channel 4 close to the suction nozzle 9 position B.

In another embodiment, in order to more accurately explain whether the user's action on the electronic cigarette is obvious enough to be sensed around the atomizer, the first air pressure sensor 2 is set at the entrance A1 of the airflow channel 4, and the second air pressure sensor 2 The sensor 3 is arranged at a position C above the airflow channel 4 close to the atomizer 5 .

The electronic cigarette in the embodiment of the present application includes a controller 1 and a first air pressure sensor 2 and a second air pressure sensor 3 respectively connected to the controller 1, wherein the first air pressure sensor 2 is set at a position in the electronic cigarette 100 that communicates with the surrounding air environment , used to detect the pressure value of the first air pressure of the surrounding air environment, and transmit 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 to detect the air flow channel The pressure value of the second air pressure on 4, and transmit the pressure value of the second air pressure to the controller 1; the controller 1 uses the pressure value between the received first air pressure value and the second air pressure value The atomizer 5 of the electronic cigarette 100 is differentially controlled to start or stop. Since the controller 1 of the electronic cigarette 100 controls the start or stop of the atomizer 5 of the electronic cigarette 100 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 airflow channel 4 , the detection of the pressure difference can be guaranteed to be consistent and controllable, and will not be affected by oil or water vapor. In this way, the sensitivity of the electronic cigarette 100 can be consistent and reliable, and will not cause false triggering or non-operation .

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 start when the pressure difference is greater than zero and greater than the predetermined pressure difference threshold. When it is equal to or less than the predetermined pressure difference threshold, the atomizer 5 of the electronic cigarette 100 is controlled not to start or to shut down. Due to the error of the detected first air pressure and the second air pressure, in order to further ensure that the atomizer 5 can really start at an appropriate time to meet the user's smoking needs, a predetermined pressure is preset in this embodiment. The difference threshold, the atomizer 5 is activated only when the pressure difference is greater than the predetermined pressure difference threshold, and when the pressure difference is equal to or less than the predetermined pressure difference threshold, the atomizer 5 of the electronic cigarette 100 is controlled not to start or close, thereby avoiding pressure Poor detection errors lead to false activation of the atomizer 5 .

The pressure value of the first air pressure is the pressure value of the first air pressure of the surrounding air environment detected in real time, and the pressure value of the second air pressure is the pressure value of the second air pressure on the airflow channel detected in real time. The real-time detection can obtain the real-time pressure difference, so that the start and stop of the atomizer 5 can be controlled in real time. That is, further, the controller 1 controls the atomizer 5 of the electronic cigarette 100 to start or stop in real time according to the real-time detected pressure difference and the predetermined pressure difference threshold.

In one embodiment, the output power of the power supply can also be adjusted according to the pressure difference, and then the amount of smoke can be adjusted. Please refer to Fig. 3, the electronic cigarette 100 also includes a power control and output circuit 6, the power control and output circuit 6 is connected to the controller 1, when the atomizer 5 is started, the controller 1 according to the real-time detected pressure difference and the controller 1 to determine the real-time output power corresponding to the pressure difference, and send the first instruction to the power control and output circuit 6, and the power control and output circuit 6 responds to the first instruction, and The real-time output power corresponding to the pressure difference is output to the nebulizer 5, so that the nebulizer 5 generates the amount of smoke corresponding to the real-time output power.

In this embodiment, the corresponding relationship between the pressure difference and the output power, and the corresponding relationship between the output power and the amount of smoke are determined in advance according to empirical values or test data. The corresponding real-time output power can be determined according to the real-time detected pressure difference, the controller 1 sends a first command to the power control and output circuit 6, and the power control and output circuit 6 responds to the first command, according to the real-time output power corresponding to the pressure difference output, so that the atomizer 5 can generate the amount of smoke corresponding to the real-time output power.

For example, preset: when there are 3-4 pressure difference units, it corresponds to 2-3 output power units; when there are 5-6 pressure difference units, it corresponds to 4-5 output power units; when there are 7-8 pressure difference units , corresponding to 6-7 output power units; 9-10 pressure difference units, corresponding to 8-9 output power units. If the real-time detected pressure difference is 4 pressure difference units, then 3 output power units will be output at this time; for another example, if the real-time detected pressure difference is 7 pressure difference units, then 6 output power units will be output at this time ;and many more.

Further, in this corresponding relationship, the greater the pressure difference, the greater the output power corresponding to the pressure difference, and the greater the amount of smoke generated by the atomizer. In this way, the user's actual smoking needs can be simulated and met, thereby improving user experience.

In one embodiment, the electronic cigarette can also judge whether the action applied by the user is "inhalation" (that is, smoking) or "breathing", which helps to accurately control the opening or closing of the atomizer. Specifically, the pressure difference is the pressure value of the first air pressure minus the pressure value of the second air pressure, and the controller 1 is configured to determine that the airflow direction of the airflow channel 4 is the direction of flow to the suction nozzle when the pressure difference is greater than zero, It is "inhalation" (smoking), and the atomizer 5 of the electronic cigarette 100 is controlled to start. When the pressure difference is less than zero, it is judged that the airflow direction of the airflow channel is the direction away from the suction nozzle, which is "blowing". Control the atomizer 5 of the electronic cigarette 100 not to start or to shut down.

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, and the controller 1 is also used to send a second instruction to the battery management circuit 8, and the battery management circuit 8 In response to the second instruction, the power supply 7 of the electronic cigarette 100 is managed.
