Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1, an electronic cigarette dry-heating prevention temperature control method according to an embodiment of the present invention includes the following steps:
s1, after the power supply device of the electronic cigarette detects and acquires a dry-burning signal of the atomization device, the heating temperature of the heating body in the atomization device is reduced from the original first constant-temperature heating temperature to the second constant-temperature heating temperature.
The first constant-temperature heating temperature and the second constant-temperature heating temperature are preset in a control circuit of the power supply device or a corresponding constant-temperature heating control unit. Normally, after the power supply device of the electronic cigarette is started, the heating body is controlled to heat and atomize the cigarette liquid at the first constant temperature heating temperature. When the power supply device does not acquire the dry-burning signal, the heating body is still heated at the first constant-temperature heating temperature.
And after the power supply device acquires the dry-burning signal, the heating body is controlled to reduce the heating temperature, and the heating is carried out at the second constant-temperature heating temperature. The reduction of the constant temperature heating temperature can be achieved by adjusting the resistance value of the heating element, and the like.
The second constant temperature heating temperature is a heating temperature lower than the first constant temperature heating temperature and is a temperature safe for the atomizing device and the human body. And the second constant temperature heating temperature is lower than the dry combustion temperature threshold value, so that the problem of dry combustion can be solved, the lower temperature can be kept for heating continuously, and particularly when the atomization device is newly injected with thick smoke liquid for immediate suction, frequent start and stop are avoided, and the atomization device is not damaged.
The dry-burning signal detected and obtained by the power supply device can be obtained through various information. For example, the resistance value of the heat generating body is changed (it is judged whether or not the dry-fire resistance value threshold is reached), the temperature value of the heat generating body is judged whether or not the dry-fire temperature threshold is reached), and the like.
And S2, continuing heating the heating body at the second constant temperature until receiving a stop signal of the power supply device.
When the user sucks again, the electronic cigarette can be normally sucked because the atomized liquid infiltrates the heating body, and no dry burning warning is generated. And after receiving a stop signal of the power supply device, the heating body stops heating.
S3, when the power supply device is started again, the heating body is heated at the first constant temperature; after the power supply device detects and acquires the dry-fire signal, the process returns to step S1.
In the circulation process of the above steps S1-S3, when the power supply device detects that the number of times of acquiring the dry-fire signal of the atomizing device reaches the set number of times within the set time, the power supply device controls the heating element to stop heating, thereby indicating that the liquid amount in the atomizing device is insufficient or exhausted.
The setting time and the number of times can be specifically set according to the capacity in the atomizing device and the condition of combining the amount of each atomization. For the above-mentioned condition that the number of times of detecting the acquired dry combustion signal of the atomization device within the set time reaches the set number of times, the corresponding default mode in the power supply device is the condition that thick smoke liquid is not newly injected and is immediately sucked, that is: when the power supply device detects that the number of times of acquiring the dry burning signal of the atomization device reaches the set number of times within the set time, the situation that thick smoke liquid is newly injected and immediately sucked is eliminated, and accordingly the situation that the liquid quantity in the atomization device is insufficient or exhausted is correspondingly solved, and therefore the power supply device controls the heating body to stop heating.
Further, when the power supply device is provided with a display module such as a display screen, the power supply device can display information such as insufficient or exhausted liquid amount in the atomization device or unsmooth circulation of newly injected thick smoke liquid through the display screen, and the display mode can be at least one of various modes such as characters, liquid amount lines, light and sound, so as to inform the user.
Referring to fig. 2, an anti-dry heating temperature control method for an electronic cigarette according to another embodiment of the present invention includes the following steps:
s1, after the power supply device of the electronic cigarette detects and acquires a dry-burning signal of the atomization device, the heating temperature of the heating body in the atomization device is reduced from the original first constant-temperature heating temperature to the second constant-temperature heating temperature.
The first constant-temperature heating temperature and the second constant-temperature heating temperature are preset in a control circuit of the power supply device or a corresponding constant-temperature heating control unit. Normally, after the power supply device of the electronic cigarette is started, the heating body is controlled to heat and atomize the cigarette liquid at the first constant temperature heating temperature. When the power supply device does not acquire the dry-burning signal, the heating body is still heated at the first constant-temperature heating temperature.
And after the power supply device acquires the dry-burning signal, the heating body is controlled to reduce the heating temperature, and the heating is carried out at the second constant-temperature heating temperature. The second constant temperature heating temperature is a heating temperature lower than the first constant temperature heating temperature and is a temperature safe for the atomizing device and the human body.
The second constant temperature heating temperature is lower than the dry-burning temperature threshold value, so that the problem of dry burning can be solved, the lower temperature can be kept for continuous heating, frequent starting and stopping are avoided, and the atomizing device is not damaged.
The dry-burning signal detected and obtained by the power supply device can be obtained through various information. For example, the resistance value of the heat generating body is changed (it is judged whether or not the dry-fire resistance value threshold is reached), the temperature value of the heat generating body is judged whether or not the dry-fire temperature threshold is reached), and the like.
And S2, continuing heating the heating body at the second constant temperature until receiving a stop signal of the power supply device.
In this embodiment, after receiving the stop signal of the power supply device, the heating element continues to heat at the second constant temperature for the set duration, so that the tobacco juice can be smoothly introduced into and infiltrate the heating element (especially when thick tobacco juice is newly injected into the atomization device and is immediately sucked), so that sufficient tobacco juice on the heating element is heated and atomized first after the power supply device is started next time. The duration can be set according to actual conditions.
And S3, when the power supply device is started again, the heating body is heated at the first constant temperature. After the power supply device detects and acquires the dry burning signal (dry burning again), the heating body is controlled to stop heating, so that the alarm of liquid shortage or exhaustion and the like in the atomization device is given.
Further, when the power supply device is provided with a display module such as a display screen, the power supply device can display information such as insufficient or exhausted liquid amount in the atomization device or unsmooth circulation of newly injected thick smoke liquid through the display screen, and the display mode can be at least one of various modes such as characters, liquid amount lines and light-up lamps, so as to inform the user.
The dry-heating prevention temperature control method of the electronic cigarette can be realized by a dry-heating prevention temperature control electronic cigarette, as shown in fig. 3 and 4, the dry-heating prevention temperature control electronic cigarette can comprise an atomizing device 10, a power supply device 20, a first constant temperature heating control unit 30 and a second constant temperature heating control unit 40. The power supply device 20 is connected with the atomization device 10, and is used for supplying power to the atomization device and controlling the atomization device to heat. The first constant temperature heating control unit 30 is connected to the power supply device 20 and the atomizing device 10, and the second constant temperature heating control unit 40 is connected to the power supply device 20 and the atomizing device 10.
The power supply device 20 controls the heating element of the atomizing device 10 to heat at the first constant temperature by the first constant temperature heating control unit 30. During normal use of the electronic cigarette, after the power supply device 20 is started, the heating body is controlled by the first constant temperature heating control unit 30 to be heated at the first constant temperature heating temperature.
After detecting and acquiring the dry-fire signal of the atomization device 10, the power supply device 20 controls the heating element to heat at the second constant-temperature heating temperature through the second constant-temperature heating control unit 40. The second constant temperature heating temperature is lower than the first constant temperature heating temperature, and the heating temperature of the heating body is reduced through control, so that continuous dry burning is avoided, and the problem of dry burning is solved.
For the detection and acquisition of the dry-burning signal, whether dry-burning occurs or not can be judged according to the resistance value change of the resistance wire (whether the resistance value threshold value of the dry-burning is reached or not) or the temperature change detected by the temperature sensor (whether the temperature threshold value of the dry-burning is reached or not) through the resistance wire or the temperature sensor arranged in the atomization device 20.
In one embodiment, as shown in fig. 3, the power supply device 20 is provided with a detection unit 21. When the detection unit 21 detects that the number of times that the power supply device 20 acquires the dry-fire signal of the atomizing device within the set time reaches the set number of times, the power supply device 20 controls the heating element to stop heating, thereby indicating that the liquid amount in the atomizing device 10 is insufficient or exhausted. The dry-heating prevention temperature control electronic cigarette of this embodiment can be used to implement the dry-heating prevention temperature control method of the electronic cigarette of the embodiment shown in fig. 1.
In another embodiment, as shown in fig. 4, the power supply device 20 is provided with a heating control unit 22. After the power supply device 20 sends the stop signal to the heating element, the heating control unit 22 controls the heating element to continue heating at the second constant temperature for the set duration. Compared with the situation of immediately stopping heating, the heating body continues to be heated at the second constant temperature according to the duration time, so that the tobacco juice can be smoothly guided into and infiltrate the heating body (particularly for thick tobacco juice), and enough tobacco juice on the heating body is heated and atomized firstly after the power supply device is started next time. The duration can be set according to actual conditions. The dry-heating prevention temperature control electronic cigarette of this embodiment can be used to implement the dry-heating prevention temperature control method of the electronic cigarette of another embodiment shown in fig. 2.
In summary, according to the dry-heating prevention temperature control method for the electronic cigarette and the dry-heating prevention temperature control electronic cigarette, when the electronic cigarette detects that the atomizing device is dry-heated, the electronic cigarette does not stop heating immediately, but reduces the constant heating temperature, so that the electronic cigarette does not scorch the smoke liquid and does not damage the atomizing device. The reduced temperature can continuously heat the tobacco juice, so that the tobacco juice can be smoothly guided to the heating body; when the user sucks the electronic cigarette again, the electronic cigarette can be normally sucked because the cigarette liquid soaks the heating body, and the dry burning alarm is not generated any more.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
