The third sensor is a temperature sensor for detecting the temperature of the atomizing chamber.

When a starting signal is acquired, the third sensor detects the temperature of the atomizing chamber, and when the temperature of the atomizing chamber is lower than the first heating temperature, the heating body starts to work to heat the atomizing chamber until the temperature of the atomizing chamber reaches a second heating temperature; when the temperature of the atomizing chamber reaches the second heating temperature, the heating body stops working, and the atomizing chamber is gradually and naturally cooled; when the temperature of atomizer chamber reduces to the third heating temperature, the heat-generating body begins work again in order to heat the atomizer chamber, reaches the second heating temperature again until the temperature of atomizer chamber, and wherein, the third heating temperature is higher than first heating temperature and is less than the second heating temperature to avoid continuously heating up the dry combustion method condition appearing to the atomized liquid in the atomizer chamber, lead to producing burnt flavor or harmful substance, and then influence the taste or cause the harm to human health.

and S11, detecting the viscosity of the atomized liquid stored in the liquid storage assembly.

when the viscosity of the atomized liquid is smaller than a preset threshold value, the micro-pump assembly is controlled to directly output the atomized liquid to the atomization assembly.

Specifically, the atomized liquid often has certain viscosity, and the viscosity of atomized liquid can be obviously reduced through the heating of certain temperature to promote the mobility and the permeability of atomized liquid, avoid causing the micropump subassembly to take place to block up and break down.

For example, the temperature for preheating the atomized liquid may be 25 to 100 ℃. The temperature for preheating the atomized liquid may be, but is not limited to, 25 ℃, 30 ℃, 40 ℃, 50 ℃, 60 ℃, 70 ℃, 80 ℃, 90 ℃ and 100 ℃.

And the micro-pump assembly 12 is used for transmitting the atomized liquid stored in the liquid storage assembly 11 to the atomization assembly 13.

Specifically, the micro-pump assembly 12 not only has a small volume, but also can precisely control the flow rate of the micro-pump assembly 12 to ensure that the atomized liquid is uniformly, continuously, precisely and slightly output.

And the atomizing assembly 13 is used for atomizing the atomized liquid transmitted to the atomizing assembly 13.

Specifically, since the flow rate of the micro pump assembly 12 can be accurately controlled, and the flow rate of the micro pump assembly 12 is a relatively fixed value, the flow rate of the micro pump assembly 12 refers to the amount of liquid passing through the micro pump assembly 12 in a unit time, the consumption value of the atomized liquid output to the atomizing assembly 13 after a single operation of the micro pump assembly 12 can be more accurately calculated according to the time data and the flow rate of the micro pump assembly 12, and finally, the residual value of the atomized liquid can be more accurately obtained by subtracting the consumption value of the atomized liquid from the original capacity value of the atomized liquid.

And the control unit 203 is used for controlling the micro-pump assembly 12 to work according to the time data and controlling the atomizing assembly 13 to start working according to the starting signal.

Specifically, firstly, when the receiving unit 201 receives the time data, the control unit 203 controls the micro-pump assembly 12 to operate according to the time data, and outputs the atomized liquid stored in the liquid storage assembly 11 to the atomizing assembly 13; then, when the receiving unit 201 receives the start signal, the control unit 203 controls the atomizing assembly 13 to start atomizing the atomized liquid; the calculation unit 202 then obtains the consumption value and the residual value of the atomized liquid through calculation.

Further, the atomizing assembly 13 may include, but is not limited to, a third sensor, an atomizing chamber, and a heat generator.

When the receiving unit 201 acquires the starting signal, the third sensor detects the temperature of the atomizing chamber, and when the temperature of the atomizing chamber is lower than the first heating temperature, the heating body starts to work to heat the atomizing chamber until the temperature of the atomizing chamber reaches the second heating temperature; when the temperature of the atomizing chamber reaches the second heating temperature, the heating body stops working, and the atomizing chamber is gradually and naturally cooled; when the temperature of atomizer chamber reduces to the third heating temperature, the heat-generating body begins work again in order to heat the atomizer chamber, reaches the second heating temperature again until the temperature of atomizer chamber, and wherein, the third heating temperature is higher than first heating temperature and is less than the second heating temperature to avoid continuously heating up the dry combustion method condition appearing to the atomized liquid in the atomizer chamber, lead to producing burnt flavor or harmful substance, and then influence the taste or cause the harm to human health.
