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, the present invention constructs a temperature control method for a split-type electronic atomizer including an atomizer and a power supply, including steps S10, S20, and S30.
The step S10 includes: temperature characteristic parameters of a heating body in the atomizing device are obtained. The temperature characteristic parameters are used for representing resistance change characteristics of the heating body at different temperatures.
Step S20 includes: and calculating the target resistance value of the heating element according to the temperature characteristic parameters and the target temperature of the heating element.
Because the relationship between the temperature of some heating elements and the resistance thereof is determined by the material of the heating element itself, for the embodiment in which the temperature of some heating elements and the resistance thereof are in a linear relationship or tend to be in a linear relationship, in step S10, the temperature characteristic parameter includes a reference temperature reference value, a temperature coefficient, and a resistance reference value corresponding to when the heating element reaches the reference temperature reference value. Accordingly, in step S20, the expression of the target resistance value is: ri = (Ti-T0) × K + R0; wherein Ri is a target resistance value, ti is a target temperature, K is a temperature coefficient, and R0 is a resistance value reference value. In addition, in the related art, the resistance value of the commonly used heat generating body generally increases as the temperature thereof increases.
In some embodiments, the heat generating body may be a heating wire.
In order to improve the calculation accuracy of the target resistance value, in some embodiments, the temperature characteristic parameter further includes a resistance value compensation coefficient which changes along with the change of the use time; correspondingly, the expression of the target resistance value is: ri = (Ti-T0) × K + J × R0, wherein J is a resistance compensation coefficient.
For some embodiments in which the temperature and the resistance of the heating element material are obviously in a nonlinear relationship, in S10, the temperature characteristic parameter includes a temperature and resistance characteristic relation. Accordingly, in S20, the method includes: and substituting the target temperature into the temperature characteristic relational expression to calculate the target resistance value.
Since the types of the atomized liquids are different, the optimal heating temperatures are also different, and in order to enhance the user experience, in some embodiments, the step S20 further includes: and determining the target temperature of the heating body according to the type of the atomized liquid of the atomization device.
The step S30 includes: and acquiring the real-time resistance value of the heating element, and controlling the power supply device to perform constant-temperature heating treatment on the heating element according to the real-time resistance value and the target resistance value so as to stabilize the real-time resistance value within the allowance range of the target resistance value.
In some embodiments, as shown in fig. 2, step S30 includes step S31, step S32, and step S33.
Step S31 includes: the real-time resistance value of the heating element is acquired based on the set frequency, and step S32 is executed.
Step S32 includes: and judging whether the real-time resistance value is larger than the target resistance value, if so, reducing the heating power of the heating element, and otherwise, increasing the heating power of the heating element. Specifically, when the real-time resistance value is larger than the target resistance value, the real-time temperature of the heating element is higher than the target temperature, and because the atomization device works, the heating element needs to exchange heat with the atomization liquid, so that the heating power of the heating element can be properly reduced to avoid sudden drop of the real-time temperature caused by taking away a large amount of heat of the heating element due to heat exchange, and thus, on one hand, the basic heat required by the atomization process is guaranteed, and on the other hand, the heating effect is prevented from being reduced due to continuous temperature rise of the heating wire; when the real-time resistance value is not larger than the target resistance value, the real-time temperature of the heating element is not yet reached to the target temperature, and in order to enable the heating element to be heated to the target temperature as soon as possible, the heating power of the heating element can be properly improved.
Step S33 includes: the power supply device is controlled to heat the heating element according to the adjusted heating power, and the process returns to S31.
It can be understood that, by repeatedly executing steps S31 to S33, the real-time resistance value of the heating element can be stabilized within the allowance range of the target resistance value, and the larger the set frequency in step S31 is, the faster the response speed of adjusting the heating power is, thereby reducing the fluctuation range of the real-time temperature, and finally improving the control precision of the real-time temperature.
In order to further stabilize the real-time resistance value of the heating element within the margin range of the target resistance value quickly and accurately, in some embodiments, the step S32 further includes: the adjustment value for the reduction and/or increase of the heating power is set based on the difference between the real-time resistance value and the target resistance value. Specifically, the adjustment value increases as the difference between the real-time resistance value and the target resistance value increases.
In order to avoid the situation that the real-time temperature reached by the heating element is inaccurate when the temperature characteristic parameter of the heating element of the new atomizing device is different from the temperature characteristic parameter of the heating element of the old atomizing device after the atomizing device is replaced, in some embodiments, the temperature control method of the split type electronic atomizing device further includes step S40. The step S40 includes: when the atomizing device replacement command is acquired, the power supply device is prohibited from heating the heating element, and the process returns to step S10. Specifically, each time the atomizer is installed (i.e., electrically connected to the power supply device), an atomizer replacement command is generated to update the temperature characteristic parameters, so as to ensure that the temperature characteristic parameters used in step S20 are matched with the atomizer. It will be appreciated that in this embodiment, the temperature characteristic of the atomizer is only obtained once the atomizer has been electrically connected.
Even if the heating elements made of the same material are manufactured by the same process technology, parameter errors cannot be avoided, and in order to further improve the accuracy of the temperature characteristic parameters of the heating elements and improve the control accuracy of real-time temperature, in some embodiments, the temperature control method of the split type electronic atomization device further comprises step S01. Step S01 includes: the temperature characteristic test is carried out on the heating body of the atomizing device before the atomizing device leaves a factory so as to obtain the temperature characteristic parameter, and the temperature characteristic parameter is stored in a memory arranged in the atomizing device.
Referring to fig. 3, the present invention also constructs a split type electronic atomizer including a power supply device, an atomizer, and a control unit provided in the power supply device.
The control unit comprises a parameter acquisition unit, a resistance value calculation unit and a heating control unit.
The parameter acquisition unit is used for acquiring the temperature characteristic parameters of a heating body in the power supply device.
The resistance value calculating unit is used for calculating the target resistance value of the heating element according to the temperature characteristic parameter and the target temperature of the heating element.
The heating control unit is used for obtaining the real-time resistance value of the heating body and controlling the power supply device according to the real-time resistance value and the target resistance value so as to perform constant-temperature heating treatment on the atomizing device.
In some embodiments, the two-piece electronic atomizer further comprises a memory for storing temperature characteristic parameters, an encryption memory, or a two-dimensional code tag. The type of the encrypted storage may be RJGT101. In addition, the memory (including the encryption memory) and the two-dimensional code label can be arranged in the atomization device, so that the heating element and the corresponding temperature characteristic parameter are bound and arranged, and the temperature characteristic parameter of the heating element is convenient to update when the atomization device is replaced.
In some embodiments, the split type electronic atomization device further comprises a wireless communication unit, and the parameter acquisition unit acquires the temperature characteristic parameter through the wireless communication unit. It can be understood that the benefit of using the wireless communication mode to carry out information interaction is that the workload of secondary development can be effectively reduced when the existing split type electronic atomization device is upgraded and modified. Alternatively, the wireless communication unit may be a bluetooth communication module or an RFID communication module.
Specifically, for the embodiment of the storage, the wireless communication unit includes a first wireless communication unit and a second wireless communication unit, the first wireless communication unit is connected with the storage, and the second wireless communication unit is connected with the parameter obtaining unit, so that the storage and the parameter obtaining unit realize information interaction; for the embodiment of the two-dimension code label, the wireless communication unit is arranged in the power supply device and is connected with the parameter acquisition unit, and after the temperature characteristic parameters stored in the two-dimension code are acquired through the mobile phone, the temperature characteristic parameters are sent to the parameter acquisition unit through the mobile phone.
