Problems solved by technology

[0004] In the existing similar aerosol generating devices, the temperature control method in the formal aerosol forming process (that is, not including the preheating process) is to gradually increase or decrease the temperature with the heating time until the aerosol is formed. until the end of the process; this method is actually only applicable to the situation where the user continues to inhale at a constant speed. For other situations, there is a phenomenon of wasting the active ingredients of the aerosol and heating energy, because no matter whether the user inhales or not, it will Continuous heating and release of volatile compounds from the aerosol-generating substrate products wastes the active ingredients of the aerosol, resulting in a poor suction experience for the user, and wastes electricity, resulting in insufficient battery life

Embodiment 1

[0105] The temperature control process in the branch preheating stage uses the preheating time as the judgment condition, and the temperature control process in the preheating stage uses reaching the last branch preheating stage as the judgment condition.

[0106] The temperature control process of the suction heating stage adopts the two parameters of the total number of suction ports and the total suction time as the end conditions of the suction heating stage at the same time. If either of the two parameters meets the end condition first, the entire temperature control process ends, and the suction branch The temperature control process in the heating stage uses the number of suction ports as the judgment condition.

[0107] Such as Figure 4 As shown, a temperature control method in the process of aerosol generation, comprising:

[0108] Step 1: The electric heating type aerosol generating device turns on the power to start the heating process.

[0109] Step 2: Call the ...

Embodiment 2

[0132] Such as Figure 5 As shown, the temperature control method in the preheating stage is the same as step 1 to step 6 in the first embodiment.

[0134] Step 7: Call the total parameters of the suction heating stage and the parameters of the suction branch heating stage 1, that is, the total number of suction ports, the total suction time, suction heating temperature 1, suction port number threshold 1, holding temperature 1, non-suction switch Holding time 1, the longest holding time 1.

[0135] Step 8: Execute the suction branch heating stage m (referring to the current suction branch heating stage, m=1 when entering this step from step 7), and control the temperature at the suction heating temperature m.

[0136] Step 9: When the aerosol generating device stops pumping, judge whether the non-puffing time reaches or exceeds the non-pu...

Embodiment 3

[0152] The temperature control process of the suction heating stage uses the total suction time as the end condition of the suction heating stage, that is, when the suction heating time reaches the total suction time, the entire heating process ends, and the temperature control process of the suction branch heating stage adopts The suction heating time or the duration of the set suction branch heating phase is used as a judgment condition.

[0153] Such as Figure 6 Shown, the temperature control method of step 1 to step 6 is the same as that of embodiment one.

[0154] Step 7: Call the total parameters of the suction heating stage and the parameters of the suction branch heating stage 1, that is, the total suction duration, suction heating temperature 1, suction heating duration 1 or suction heating time threshold 1.

[0155] Step 8: Execute the suction branch heating stage m (referring to the current suction branch heating stage, m=1 when entering this step from step 7), an...

Description

technical field [0001] The invention relates to the technical field of aerosol generation, in particular to an aerosol generation device and a temperature control method in the aerosol generation process. Background technique [0002] Traditional cigarettes directly ignite tobacco, and tobacco burns at a high temperature of 700°C to 1200°C, resulting in more than 4,000 kinds of toxic substances harmful to human body, such as tar, nicotine, phenols, alcohols, acids, aldehydes, etc. Health can be very dangerous. However, with the gradual development of the tobacco industry, heat-not-burn tobacco has become an emerging industry. Compared with the ignition temperature of traditional tobacco, the temperature of new tobacco heating appliances is controlled at 230°C to 385°C. Reduce 90% to 95% of harmful substances, without producing tar and soot, thereby reducing harm. [0003] In the existing aerosol generating device, the aerosol generating substrate product is heated by a hea...
