Description

Electronic cigarette atomizer heating wire heating method and electronic cigarette

Technical field

[0001] The present invention relates to the field of electronic cigarette technology, and in particular, to an electronic cigarette atomizer heating wire heating method and an electronic cigarette.

Background technique

[0002] Electronic cigarette is a relatively common simulated cigarette electronic product, mainly used for smoking cessation and alternative cigarettes; the structure of electronic cigarette mainly includes battery assembly and atomizer assembly; when smoker's smoking action is detected, battery assembly Powering the atomizer assembly, the atomizer assembly is in the squirm state; when the atomizer assembly is turned on, the heating wire is heated, and the smoke oil is evaporated by heat to form an aerosol that simulates the smoke, thereby allowing the user to The electronic cigarette smoking has a feeling similar to the smoke.

[0003] The atomization temperature of the smoke oil is usually 240 ° C ~ 300 ° C, that is, under normal working conditions, the heating temperature of the heating wire for atomizing the smoke oil in the atomizer assembly is 240 ° C ~ 300 ° C . After the atomizer assembly is just turned on, the battery pack needs to preheat the atomizer heating wire so that the heating wire can quickly reach the temperature requirement of the user (such as 240 ° C ~ 300 ° C). In the early days, the battery assembly directly used a fixed power output to drive the nebulizer heating wire to preheat, for example, the battery assembly directly supplied a constant voltage of 3.6V to the heating wire. However, when the atomizer assembly is just turned on, the temperature of the heating wire is variable. Specifically, the following two conditions are included: 1) When the user is not smoking (such as 3h, 10h, etc.), the temperature of the heating wire is Ambient temperature (usually below 40 °C), 2) When the user's smoking interval is very short (such as 5s), the heating wire temperature is higher than the ambient temperature (such as 100 °C). The battery component transmits a certain amount of energy to the atomizing device heating wire (for example, all uses 3.6V full power for 2 seconds to preheat, the power is 6W); for case 1), the output to the atomizer heating wire is used. In the manner of fixed driving power, the temperature of the heating wire can rise to a normal temperature range (for example, 240 ° C to 300 ° C) required for atomization of the smoked oil in the stage of heating the atomized smoke oil, but the heating wire mentioned above The heating method requires a little longer time, and the user experience is not high enough. For the case 2), the heating wire is just turned on, and the initial temperature is high. When using this heating method to output a fixed driving power to the atomizing device heating wire吋, it is very likely that the temperature of the heating wire after heating is quite high, causing burning of cotton.

[0004] In the later stage, in view of the above problem 1), the problem of slightly longer heating time, some controllers are used in the electronic cigarette. It is used to start the smoking atomizer assembly. The battery module first performs a slightly higher power output (such as 3.7V/7 W) to drive the heating wire to heat quickly (such as Is), and then output the normal driving power ( Such as 3.6V/6W); this kind of initial conduction, output slightly higher power, can solve the problem of slightly longer preheating in the above case 1), but there is no improvement for the above case 2).

[0005] It can be seen that in the prior art, when the atomizing heating wire is just turned on and the temperature of the heating wire is high, the battery component drives the heating wire to work, which causes the temperature to rise too high or even to burn the cotton.

[0087] Embodiment 1

Referring to FIG. 1, an embodiment of the present invention provides a heating method for an electronic cigarette atomizer heating wire, and the heating method includes the following steps:

[0089] Sl, detecting an initial temperature of the heating wire for atomizing the smoke oil in the atomizer assembly after detecting the smoking signal;

[0090] S2. Calculating, according to the initial temperature and a target temperature stored in the electronic cigarette, a preheating driving power obtained to drive the heating wire to work and rise from the initial temperature to the target temperature;

[0091] S3, driving the heating wire to operate according to the preheating driving power, when the heating wire is driven by the preheating driving power, the heating is preset, the heating temperature meets the preset temperature condition, and the heating is stopped. The preheating drive power drives the heating wire to operate and drives the heating wire to operate with normal driving power.

[0092] In a specific implementation process, referring to FIG. 2, the electronic cigarette includes a battery assembly 1 and an atomizer assembly 2, and the battery assembly 1 is connected to the atomizer assembly 2 through a single-wire interface J2 and a two-wire interface J1; The atomizer assembly 2 is provided with a heating wire 21 for atomizing the smoke oil, and a temperature sensor 221 for detecting the temperature of the heating wire 21 or the ambient temperature around the heating wire 21; the battery assembly 1 is provided with: a smoking action The detecting module 101 is configured to detect a smoking action of the user, and obtain a smoking signal; and control connected to the smoking action detecting module 101 The module 102 is configured to receive and control the electronic cigarette operation based on the smoking signal; and the temperature detecting module 103 connected to the control module 102 and the temperature sensor 221 is configured to receive the atomizing heating wire issued by the control module 102. The temperature detection command of the temperature of 21, the temperature detection command is executed and the current temperature value of the heating wire 21 is obtained, wherein the temperature detecting module 103 is connected to the temperature sensor 221 via the interface J2.

[0093] Specifically, the electronic cigarette is provided with a check button (not shown in FIG. 2) connected to the smoking action detecting module 101 for indicating that the user smokes in the closed state and that the user is not smoking in the broken state, or Provided with a smoking action detecting module 101 for detecting a negative pressure, indicating that the user smokes and no negative pressure is detected, indicating a negative pressure sensor for non-smoking (eg, a microphone, not shown in FIG. 2) In the embodiment, the negative pressure refers to an atmospheric pressure of the electronic cigarette in which the atmospheric pressure in the electronic cigarette is less than the atmospheric pressure outside the electronic cigarette; when the shut-off button is detected to be closed or the negative pressure sensor is detected Detecting the negative pressure 吋, the smoking action detecting module 101 generates a smoking signal indicating that the user is smoking; the control module 102 sends the temperature detecting command to the temperature detecting module 103 based on the smoking signal indicating that the user is smoking, The temperature detecting module 103 is caused to execute the temperature detecting command and acquire the current temperature value of the heating wire 21.

[0094] Wherein, the temperature sensor 221 can use any temperature detecting component, such as a thermal resistance type component (such as a thermal resistance, a thermistor), a thermal expansion type temperature component (such as a bimetal, a temperature switch), and a thermoelectric effect type. Components (such as thermocouples). Specifically, taking the temperature sensor 221 as a thermistor as an example, as shown in FIG. 3, the atomizer heating wire 21 can be wound around the temperature sensor 221 (ie, the thermistor), and the thermistor can also be It is disposed at a position close to the periphery of the atomizing heater heating wire 21 to realize temperature detection of the atomizing device heating wire 21 by the temperature sensor 221.

[0095] In a specific implementation process, the electronic cigarette detects the initial temperature of the heating wire by using a thermistor whose resistance value is proportional to the temperature, that is, the temperature sensor 221 can be a PTC type thermistor (ie, the temperature rises). The sorghum resistance is increased or the NTC type thermistor (ie, the temperature rises and the resistance decreases). Referring to FIG. 4, the step S2 includes the sub-steps: S25: reflecting the initial temperature of the thermistor The initial resistance value is converted into an initial voltage signal; S26, based on the initial voltage signal and the target temperature, calculating a preheating driving power that drives the heating wire to operate and rises from the initial temperature to the target temperature. That is, the temperature sensor 221 detects the temperature of the atomizing heating wire 21, and its resistance value changes with the temperature value of the atomizing heating wire, and the temperature detecting module 103 detects the voltage value across the temperature sensor 221, The temperature value of the heating wire 21 is determined. [0096] Next, after performing the above step S2, the control module 102 calculates the heating wire 21 from the initial temperature to the reference based on the initial temperature and the target temperature, based on the fastest preheating time (such as Is). The preheating drive power required for the target temperature. Further, still referring to FIG. 2, the control module 102 is further connected to the battery module 104 (including the battery, the battery control unit, and the battery charging unit); the battery assembly 1 is further provided with the control module 102 and the atomizing heating wire 21. The atomizer driving module 105 is configured to cooperate with the battery module 104 under the control of the control module 102, and drive the atomizing heating wire 21 to generate heat according to different initial driving temperatures of the atomizing heating wire 21, The atomizer drive module 105 is connected to the heating wire 21 through the interface J1.

[0097] In the specific implementation process, on the basis of the electronic cigarette hardware structure shown in FIG. 2, the present invention actually provides two schemes for heating the atomizing heating wire, which is embodied in the above step S3:

[0098] 1) A measurement standard for converting the driving power of the heating wire 21 from the preheating driving power to the normal driving power by heating the turns:

Referring to FIG. 5, in the step S3, the heating wire is driven to operate according to the preheating driving power, and when the heating wire is heated at the preheating driving power, the preset time is stopped, and the stopping is performed. The preheating driving power drives the heating wire to operate, and the driving of the heating wire is driven by a normal driving power, including the following substeps:

[0100] S31. Estimating the preset time based on the preheating driving power.

[0101] S32, driving the heating wire to operate with the preheating driving power, and when the heating wire heats the predetermined turn in the preheating driving power, stopping driving power with the preheating The heating wire is driven to operate, and the heating wire is driven to operate with the normal driving power.

[0102] 2) The heating temperature is used as the measurement standard for the driving power of the heating wire 21 to be converted from the preheating driving power to the normal driving power:

Referring to FIG. 6, in the step S3, the heating wire is driven based on the preheating driving power, and when the heating wire is driven by the preheating driving power, the heating temperature satisfies a preset temperature condition. Stop driving the heating wire with the preheating driving power, and drive the heating wire to operate with normal driving power, including the following substeps:

[0104] S33, driving the heating wire to operate based on the preheating driving power, and monitoring the heating temperature of the heating wire; S34: When the heating temperature meets the preset temperature condition, stop driving the heating wire to operate with the preheating driving power, and drive the heating wire to operate with the normal driving power.

[0106] For the above scheme 1), although the preheating driving power is calculated based on the fastest preheating time, the calculation standard is based on the standard state of the electronic cigarette factory, the atomizing heating wire (ie, zero) In the actual application, the heating wire 21 is worn out and the ambient temperature is indefinite. Therefore, in order to accurately measure the heating wire 21 according to the actual situation, the standard value such as the state of wear and the standard ambient temperature (for example, 20 ° C) is present. Heating is performed to raise the temperature of the heating wire 21 to an appropriate temperature range.
