detailed description

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

In a first aspect, an embodiment of the invention provides an atomizer, such as an atomizer for an electronic cigarette. Referring to Figure 2, there is included a reservoir 1 for storing an aerosol-forming substrate and an atomizing assembly 2 in communication with the reservoir 1, the atomizing assembly 2 comprising a first atomizing aerosol-forming substrate a heating element 201 and a liquid guiding element 202,

The atomizer further includes a second heating element 3 for preheating the aerosol-forming substrate.

Specifically, the embodiment of the present invention is described by taking an atomizer for an electronic cigarette as an example. The liquid storage chamber 1 functions as an aerosol-forming substrate for storing electronic cigarettes, and can be variously configured according to the design requirements of the electronic cigarette. Deformation. For example, referring to Fig. 2, in one embodiment of the present invention, the liquid storage chamber 1 may be composed of an atomizing tube 101, a liquid storage tube 102, an upper cover 103 and a base 104 to form an aerosol-forming substrate. a sealing space; the liquid guiding member 202 in the atomizing assembly 2 is in communication with the liquid storage chamber 1 for absorbing the aerosol-forming substrate in the liquid storage chamber 1, and the liquid guiding member 202 may be a linear structure such as a cotton thread. The two ends respectively pass through the liquid storage tube 102 and enter the inside of the liquid storage chamber 1. The portion of the liquid guiding element 202 located in the atomizing tube contacts the first heating element 201. In a possible embodiment, the first The heating element 201 is a heating wire that is wound around the liquid guiding element 202. In other possible embodiments, the first heating element 201 may be a heat generating sheet, a heat generating plate, and a heat generating tube, which is not limited in this embodiment. The inner space of the atomization tube 101 constitutes an air flow passage 5, and the air flow direction is indicated by a broken line with an arrow in FIG. 2, and the top of the air flow passage 5 is generally provided with a cigarette holder 6 for sucking after atomization in the air flow passage 5. The gaseous aerosol forms a matrix.

It should be noted that, unless otherwise specified, the aerosol-forming substrate described in the embodiments of the present invention includes a liquid or a gel, and the aerosol-forming substrate may specifically be a smoky oil, a propylene glycol solution, a plant glyceride, a flavoring agent, Spices, etc.

During use, the aerosol-forming substrate in the reservoir chamber 1 is preheated by using the second heating element 3 located inside the reservoir chamber 1 to increase the temperature of the aerosol-forming substrate and reduce the viscosity. The fluidity is increased, and can be quickly absorbed by the liquid guiding member 202, and then the aerosol forming substrate absorbed by the liquid guiding member 202 is atomized by the first heating member 201, and the mist is sucked in the airflow passage 5 through the mouthpiece 6. The gaseous aerosol after formation forms a matrix. Thereby, it is solved that the aerosol-forming substrate is not absorbed by the liquid-conducting element 202 due to the high viscosity of the aerosol-forming substrate or the poor fluidity of the aerosol-forming substrate, so that the first heating element 201 is dry-fired.

In the embodiment of the invention described above, the first heating element 201 and the second heating element 3 are independently disposed, that is, in the embodiment of the invention, the first heating element 201 needs to be separately disposed. Second heating element 3. However, if the first heating element 201 and the second heating element 3 have only some connection relationship instead of being formed integrally, it should be considered that the first heating element 201 and the second heating element 3 are independently provided.

Regarding the shape of the second heating element 3, there is no specific limitation. For example, the second heating element 3 may be an inverted L shape, a strip shape or a sheet shape, and the second heating element 3 may also be a cylinder between the atomization tube 101 of the liquid storage chamber 1 and the liquid storage tube 102, the shape of the cylinder body should be determined according to the specific shape of the liquid storage chamber 1, when the liquid storage chamber 1 is a cylinder The cylinder may be a cylindrical cylinder correspondingly. When the liquid storage chamber 1 is a rectangular parallelepiped, the cylinder may be a rectangular parallelepiped cylinder.

As shown in FIG. 2, in an embodiment of the present invention, the second heating element 3 is a cylinder that is sleeved outside the atomizing assembly 2, that is, a cylinder that is sleeved outside the atomizing tube 101, and the cylinder will The liquid storage chamber 1 is partitioned into two spaces, a first annular space X1 between the atomizing tube 101 and the second heating element 3 and between the liquid storage tube 102 and the second heating element 3 a second annular space X2 having a liquid inlet hole 3a in the second heating element 3, the first annular space X1 and the second annular space X2 communicating through the liquid inlet hole 3a, wherein the liquid inlet hole 3a is located in the first The bottom of the heating element 3, in a possible embodiment, the bottom refers to the lower third of the second heating element 3; in other possible embodiments, the bottom may be the second heating Other positions of the lower portion of the component 3 are not limited in this embodiment. It can be seen that the second heating element 3 shown in Fig. 2 is in the form of a circular tube, which can make the aerosol-forming substrate located inside the liquid storage chamber 1 more uniformly heated, and can ensure the overall flow direction of the aerosol-forming substrate. The heat conducting element 3 is sufficiently absorbed and utilized.

As shown in FIG. 3, in another embodiment of the present invention, the second heating element 3 is inverted L-shaped, and is fitted to the portion of the liquid guiding member 202 shown in FIG. 3 located in the liquid storage chamber 1, as shown in FIG. The portion of the liquid guiding member 202 located in the liquid storage chamber 1 is also inverted L-shaped, so that the second heating element 3 is also absorbed by the liquid guiding member 202 after the aerosol forming substrate located near the liquid guiding member 202 can be heated. It is set to an inverted L shape, and the inverted L shape here refers to a cross-sectional view of an inverted L shape, and the specific form thereof may be a strip-shaped inverted L structure or a cylindrical inverted L structure. In the shape of the liquid guiding member 202, when the shape of the portion of the liquid guiding member 202 located in the liquid storage chamber 1 is the remaining form, for example, in the form of a straight line, the second heating element 3 may also be according to the liquid guiding member 202. The shape is adjusted accordingly, and becomes a strip or the like.

The position of the second heating element 3 inside the liquid storage chamber 1 is also not particularly limited as long as heating of the aerosol-forming substrate inside the liquid storage chamber 1 can be achieved. Specifically, in an embodiment of the present invention, the second heating element 3 is located at a communication between the liquid guiding element 202 and the liquid storage chamber 1, and the liquid guiding element 202 and the liquid storage chamber 1 are at this time. The communication is referred to in the vicinity of the communication between the liquid guiding member 202 and the liquid storage chamber 1. For example, it is a position in which the liquid element 202 is in contact with the tube wall of the atomizing tube 101 and a position within a predetermined distance from the position, that is, the communication portion herein refers not only to the contact surface where the two are in contact, but also includes The distance from the contact surface is equal to the position within the range of the distance between the atomizing tube 101 and the reservoir tube 102 of the reservoir chamber 1. Referring to Fig. 3, the second heating element 3 heats the aerosol-forming substrate located adjacent to the liquid-conducting element 202. When the fluidity of the aerosol-forming substrate located near the liquid-conducting element 202 is increased, the liquid-conducting element 202 can be absorbed sufficiently. The aerosol forms a matrix to avoid dry burning of the first heating element 201. Although the implementation of the second heating element 3 at the junction of the liquid guiding element 202 and the reservoir 1 is provided herein, the invention is not limited thereto. For example, the second heating element 3 may also be located at an upper portion, a middle portion, or a lower portion of the liquid storage chamber 1, or may be connected to the upper cover 103 and the base 104 in a top-down manner. When the number of the second heating elements 3 is two or more, that is, a plurality, the plurality of second heating elements 3 may be distributed in the liquid storage chamber 1 in a uniform or uneven manner. internal. For example, a plurality of second heating elements 3 are provided in the lower portion of the liquid storage chamber 1, or a plurality of second heating elements 3 are provided in the upper portion of the liquid storage chamber 1.

In still another embodiment of the present invention, the second heating element 3 may also be disposed on at least one cavity wall of the liquid storage chamber 1, and the at least one cavity wall is an atomization tube 101 and a liquid storage tube 102. At least one of them. At this time, the liquid storage chamber 1 which is not divided can be provided, so that the resistance at the time of loading or flowing of the aerosol-forming substrate can be reduced. For example, when the specific structure of the liquid storage chamber 1 is constituted by the atomizing tube 101, the liquid storage tube 102, and the like as described above, the second heating element 3 may be disposed on the atomizing tube 101, and may be disposed in the The liquid storage tube 102 can also be disposed on the atomization tube 101 and the liquid storage tube 102 at the same time, that is, the second heating element 3 is disposed on the inner wall of the chamber wall of the liquid storage chamber 1. Such an arrangement makes the structure of the liquid storage chamber 1 compact and saves space.

In addition, for the basic arrangement of the atomizer, it should be further explained that since the aerosol-forming substrate storage has a sealing requirement, the neighboring technician can understand that the liquid storage chamber 1 is stored by the atomizing tube 101. The liquid tube 102, the upper cover 103 and the base 104 are formed to form a sealed cavity. The upper cover 103 and the base 104 may be connected to the atomizing tube 101 and the liquid storage tube 102 in the form of threads, so as to facilitate installation and disassembly when the aerosol forming matrix is added to the liquid storage chamber 1, or in the liquid storage chamber 1 A feeding port that can be opened or closed is provided, and an aerosol forming matrix is added to the liquid storage chamber 1 through the feeding port. At the same time, in order to ensure the tightness of the liquid storage chamber 1, the joint between the atomizing tube 101, the liquid storage tube 102 and the upper cover 103 and the base 104 is sealed by a sealing member 7, which is usually sealed with rubber. The ring can also be sealed with other sealing forms such as Teflon.

Referring to FIG. 2, the liquid guiding member 202 is connected to the liquid inlet hole 3a, and the end portion 202E of the liquid guiding member 202 extends toward the bottom of the liquid storage chamber 1 to facilitate absorption of gas located at the bottom of the liquid storage chamber 1. The sol forms a matrix. The portion of the liquid guiding member 202 located in the atomizing tube 101 surrounds the first heating element 201, so that the aerosol-forming substrate absorbed on the liquid guiding member 202 can be heated uniformly. The specific form of the first heating element 201 can be Heating wire, heating tube, heating sheet and heating plate, etc., are conventional settings. The portion of the liquid guiding member 202 outside the liquid storage chamber 1 may be perpendicular to the flow direction of the air flow in the air flow passage 5. In addition, the second heating element 3 includes a heating wire, an electric heating rod, or a heating sheet electrically connected to the power source, and a metal casing that is sleeved on the heating wire, the electric heating rod, or the electric heating sheet. Here, the second heating element 3 can be a constant resistance element, that is, a heating wire, a heating rod, or a heating sheet having a constant resistance value, and the resistance value does not change with temperature, and constant power can be realized. heating. In addition, the function of the above metal casing is to protect the heating element, the electric heating rod, or the electric heating sheet and the like directly contacting the power source to generate heat, so that it does not directly contact the aerosol forming substrate, and the metal casing has good heat conduction. When the specific shapes of the directly heat generating components located in the metal casing are inconsistent, the specific shape of the entire second heating element 3 can be adjusted by the metal casing.

As a preferred embodiment of the above embodiment of the present invention, the atomizer further includes a sensor, which is a temperature sensor 4 located in the liquid storage chamber 1, and can be used for detecting the aerosol in the liquid storage chamber 1. The temperature at which the substrate is formed can also be used to detect the temperature of the second heating element 3, and can also be used to detect the temperature of the chamber wall (e.g., the atomizing tube 101, the reservoir tube 102) of the reservoir chamber 1. Therefore, the temperature sensor 4 can be located at the liquid guiding element 202, or at the second heating element 3, or on the cavity wall of the liquid storage chamber 1 (for example, the atomizing tube 101, the liquid storage tube 102). . The sensor may also be selected from at least one of a vibrating sensor, a gravity sensor, a pressure sensor, and a touch sensor, and may be disposed on the inner wall of the liquid storage chamber 1 or in the air flow passage 5 at this time.

In a second aspect, embodiments of the present invention provide an atomizing device comprising the atomizer described above, and a power source electrically coupled to the first heating element 201 and the second heating element 3 of the atomizer. Since the atomizer described above is included, damage of the atomizing assembly due to dry burning is avoided.

In a third aspect, an embodiment of the present invention provides a control method for controlling the atomizer described above. Referring to FIG. 4, the method includes the following steps:

Step a): opening the second heating element 3 to preheat the aerosol-forming substrate in the liquid storage chamber 1 with a first heating power, so that the aerosol-forming substrate is absorbed by the liquid-conducting element 202;

Step b): opening the first heating element 201 to atomize the aerosol-forming substrate absorbed by the liquid-conducting element 202.

The embodiment of the present invention controls the atomizer described above in two steps, which is based on the control of the second heating element 3 and the first heating element 201 in the atomizer to achieve the temperature of the aerosol-forming substrate. The rise, the decrease in viscosity, and the increase in fluidity are well absorbed by the liquid-conducting element 202, and then the aerosol-absorbed matrix is absorbed by the liquid-conducting element 202. Specifically, first, the second heating element 3 is first turned on to heat the aerosol-forming substrate, so that the aerosol-forming substrate is absorbed by the liquid-conducting element 202; then, the first heating element 201 is turned on again. The aerosol-forming substrate absorbed by the liquid-conducting element 202 is atomized. That is, the aerosol-forming substrate is pre-heated before atomizing the aerosol-forming substrate, and the pre-heating temperature is lower than the atomization temperature of the aerosol-forming substrate, and the effect is to increase the temperature of the aerosol-forming substrate to gas. The sol-forming substrate may be absorbed by the liquid-conducting element 202. Before the aerosol-forming substrate is atomized, the liquid-conducting element 202 is sufficiently absorbed by the aerosol-forming substrate, and then the first heating element 201 is opened to the aerosol-forming substrate. When the atomization is performed, the dry condition of the first heating element 201 can be effectively avoided, and the occurrence of burnout of the atomizer can be further avoided.

Of course, the above is only to first open the second heating element, and then turn on the first heating element to exemplify, optionally, in actual implementation, the above two steps can also be performed simultaneously, or first open the first heating element and then open the second The heating element is not limited in this embodiment.

Wherein, the first heating power described above means that the second heating element 3 can be heated to form an aerosol forming matrix, thereby increasing the fluidity of the aerosol-forming substrate, so that the aerosol-forming substrate becomes available to the liquid-conducting member 202. Better absorbed power. In particular, the first heating power can be set according to the specific form of the second heating element 3. For example, when the second heating element 3 itself is a heating element capable of adjusting the heating power, the value of the first heating power can be directly set, and the heating element capable of adjusting the heating power can be specifically a heating element with adjustable resistance. Adjusting the value of the first heating power by changing the resistance value of the heating element; when the second heating element 3 is a heating element having a fixed resistance value, the first heating power may be determined by setting a voltage preset value . The embodiment of the present invention does not specifically limit the magnitude of the first heating power as long as the first heating power enables the second heating element 3 to be heated to allow the aerosol-forming substrate to be absorbed by the liquid-conducting element 202.

In another embodiment of the invention as shown in Figure 5, step a)) is further included between step a) and step b), by step axb) it can be determined whether the aerosol-forming substrate has become available The fluid guiding element 202 absorbs.

Specifically, step axb): detecting whether the second heating element 3 reaches a first preset temperature, and if so, turning off the second heating element 3, and if not, continuing to maintain the second heating element 3 Open state. The first predetermined temperature means that the fluidity of the aerosol-forming substrate is significantly enhanced at this temperature, and can be better absorbed by the liquid-conducting member. Further, the first preset temperature may vary depending on the aerosol forming matrix, and may be, for example, 30 ° C, 40 ° C, or 50 ° C, or the like. The detecting whether the second heating element 3 reaches the first preset temperature may be implemented in various manners. For example, it may be directly detected by the temperature sensor whether the temperature of the second heating element 3 reaches the first preset temperature, or First, by detecting the time required for the temperature of the second heating element 3 to reach the first preset temperature, and indirectly detecting whether the temperature of the second heating element 3 reaches the first time by detecting whether the heating time of the second heating element 3 reaches the time A preset temperature.

In another embodiment of the present invention, as shown in FIG. 6, a step axb) is further included between step a) and step b), and it can be determined by step axb) whether the aerosol-forming substrate has become available The fluid guiding element 202 absorbs.

Specifically, step axb): detecting whether the second heating element 3 reaches a first preset temperature, and if so, turning off the second heating element 3 and issuing a warning signal to the outside, if not, continuing to maintain the The open state of the second heating element 3. The warning signal sent to the outside while the second heating element 3 is turned off can be realized by an audible and visual alarm, a vibration alarm, etc., and the user can be reminded that the aerosol-forming substrate has been heated to a good fluidity and can be The liquid guiding element 202 absorbs and also reminds the user that step b) can be entered at this time.

In the embodiments described above, specific determinations can be made by the specific method in step axb) to determine whether the aerosol-forming substrate has become absorbing by the liquid-conducting element 202. In order to make the judging process more convenient and rapid during actual use, the process may also be to observe whether the fluidity of the aerosol-forming substrate is increased by visual observation. That is, it can be judged by visual observation whether the fluidity of the aerosol-forming substrate is increased to determine whether the aerosol-forming substrate has become absorbed by the liquid-conducting element 202, and when the fluidity of the aerosol-forming substrate is observed to increase, the gas is indicated. The sol-forming substrate has become absorbing by the liquid-conducting element 202, and the user can thus proceed to step b).

Referring to FIG. 7, in another embodiment of the present invention, after the step b), the method may further include: step c): detecting a pumping frequency of the user, if the pumping frequency is greater than the first preset frequency Using the second heating element 3 to heat the aerosol-forming substrate in the liquid storage chamber 1 at a second heating power, where heating at the second heating power may be continuous heating. The second heating power is less than the first heating power. If the pumping frequency is less than the first preset frequency, a reminder signal is sent to the outside, and the reminding signal can be sent through an audible and visual alarm, a vibration alarm, or the like. Specifically, the user may be reminded that the fluidity of the aerosol-forming substrate may be deteriorated at this time, and whether the temperature of the aerosol-forming substrate is lower than the first preset temperature, and if so, the next step is performed in the next step b. If not, it is not necessary to enter step a when the next step b is performed. The detection of the pumping frequency of the electronic cigarette user may be in various forms. Specifically, the pumping frequency of the detecting electronic cigarette user may also be detected by the cooperation of the speed measuring component and the timing component, by detecting the airflow. The gas flow rate in the channel 3 is less than the preset time value of the flow rate; if the time length is less than the time preset value, the pumping frequency is greater than the first preset frequency, and if the time length is greater than the time preset value, The pumping frequency is less than the first preset frequency. The detecting the suction frequency of the electronic cigarette user may also be indirectly reacted by the temperature measured by the temperature sensor. When the temperature sensor detects that the temperature of the second heating element 3 is below the second temperature preset value, the pumping is illustrated. The suction frequency is less than the first predetermined frequency, where the second temperature preset value may be a temperature at which the aerosol-forming substrate is not absorbed by the liquid-conducting element 202 at the temperature.

Wherein the use of the second heating element 3 to heat the aerosol-forming substrate in the liquid storage chamber 1 with a second heating power, and the second heating power is less than the first heating power, that is, by the The second heating element 3 thermally or thermally compensates the aerosol-forming substrate, and the second heating power can likewise be set according to the specific form of the second heating element 3. In actual use, the heat preservation or heat compensation of the aerosol-forming substrate by the second heating element 3 can be realized in two ways, that is, the above-mentioned automatic control by the internal detection and control mode of the electronic cigarette, Another way is to visually observe the fluidity of the aerosol-forming substrate. That is to say, whether the fluidity of the aerosol-forming substrate can be judged by visual observation to determine whether the fluidity of the aerosol-forming substrate requires heat preservation or heat compensation for the aerosol-forming substrate, when the aerosol-forming substrate is observed to have poor fluidity. , indicating that the aerosol-forming substrate has become unabsorbable by the liquid-conducting element 202, and the aerosol-forming substrate may be insulated or thermally compensated by non-automatic control, such as activation and the second heating element 3 a switch or the like connected, and when heated to a first preset temperature, the flow of the smoke liquid can be visually observed, and when the fluidity of the aerosol-forming substrate becomes good and can be absorbed by the liquid-conducting element 202, the A switch to which the second heating element 3 is connected.

The reminding signal sent to the outside, including sound and light reminders and vibration reminders, is used to remind the user that the fluidity of the aerosol-forming substrate may be deteriorated without aerosolization for a long time, and aerosol formation may occur. The substrate may need to be heated again at a first heating power.

Referring to FIG. 8, in still another embodiment of the present invention, after the step b), the method further includes: step c): detecting a user's pumping frequency, if the pumping frequency is greater than the first preset frequency, Then, the second heating element 3 is used to heat the aerosol-forming substrate in the liquid storage chamber 1 , and if the pumping frequency is less than the first predetermined frequency, a warning signal is sent to the outside. Wherein, the embodiment of the present invention does not specifically define the manner of intermittently utilizing the frequency of the second heating element 3 and whether it is a constant period, but must satisfy the heat preservation effect or heat compensation effect on the aerosol-forming substrate to make the aerosol A state in which the matrix remains absorbing by the liquid guiding member 202 is formed. For example, in particular, the intermittent heating of the aerosol-forming substrate in the liquid storage chamber 1 by the second heating element 3 can also be realized in two ways, one way being through the interior of the electronic cigarette. The detection control mode realizes automatic control, that is, when detecting that the user's pumping frequency is greater than the first preset frequency, the second heating element 3 periodically heats the aerosol-forming substrate in a manner that the second predetermined frequency is turned on. The opening power of the second heating element 3 is not limited herein. For example, the heating power of the second heating element 3 may be a third heating power between the first heating power and the second heating power, or may be the first heating. Power or second heating power. Another way is to observe whether the fluidity of the aerosol-forming substrate is deteriorated by visual observation. When the fluidity of the aerosol-forming substrate is observed to be deteriorated, it indicates that the aerosol-forming substrate has become difficult to be absorbed by the liquid-conducting element 202, The aerosol-forming substrate is thermally or thermally compensated by means of non-automatic control, such as a switch or the like connected to the second heating element 3, and when heated to a first preset temperature, the smoke can be visually observed. In the case of liquid flow, when the fluidity of the aerosol-forming substrate becomes good and can be absorbed by the liquid-conducting element 202, the switch connected to the second heating element 3 is turned off, and the process of visual observation may not be a constant period. The frequency at which the second heating element 3 is used at intervals is also not constant.

In another embodiment of the present invention as shown in FIG. 9, before step a), the method further includes:

Step 1a): It is judged whether the sensor for detecting an external signal detects an external signal, and if so, proceeds to step a), if not, the second heating element is not turned on. Specifically, in the embodiment, the electronic cigarette is further provided with a sensor for detecting an external signal, and the sensor for detecting the external signal may be various, such as a vibration sensor, a gravity sensor, a pressure sensor, and a touch. According to different types of sensors, detecting the corresponding external signal can be used as a trigger condition for entering step a). For example, after detecting an external signal such as an external force grip by a pressure sensor, the step can be entered. a); after the vibration sensor detects a vibration of a predetermined amplitude or frequency of the outside, it can proceed to step a).

It can be understood by those skilled in the art that, in general, the step a) is adopted by means of opening the control switch, and the control switch can be in various forms, for example, the control switch can be one, and the control switch can be detected. It is determined whether or not to enter step a) by the length of time pressed by the outside world. Then, whether or not the other steps such as step b) can be determined by detecting the length of time that the control switch is pressed by the outside; the control switch can also be multiple. Different control switches are used to determine the steps to go. In addition, by using the control switch to enter the respective steps corresponding thereto, correspondingly, the respective steps corresponding thereto can also be exited by the control switch.

It will be understood by those skilled in the art that in the above-described embodiments, when the second heating element 3 is plural, in step a), at least one second heating element 3 has a first heating power. Heating the aerosol-forming substrate in the liquid storage chamber 1 and at least one of the first heating element 3 is required to preheat the aerosol-forming substrate in the liquid storage chamber 1 at a second heating power The heating element 3 heats the aerosol-forming substrate in the liquid storage chamber 1 with a second heating power. For example, when the second heating element 3 is four, a second heating element 3 may be used for the first heating. The gas is heated to the aerosol-forming substrate in the liquid storage chamber 1. When necessary, the other three second heating elements 3 heat the aerosol-forming substrate in the liquid storage chamber 1 at a second heating power. That is, heat preservation.

The above is exemplified only by automatically controlling the second heating element 3. In actual implementation, it is also possible for the user to determine whether to open the second heating element 3 according to subjective judgment.

Moreover, since the same component of the liquid smoke has different viscosity at different ambient temperatures, in order to save electrical energy, before the second heating element 3 is turned on, the ambient temperature can also be detected first, and the ambient temperature is pre-empted. When the temperature is set, it indicates that the temperature is higher at this time, and the viscosity of the smoke liquid is good. At this time, step b) can be directly performed. Conversely, if the ambient temperature does not reach the preset temperature, the second heating element 3 can be turned on first. I will not repeat them here.
