Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0028] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] The inventors of the present application have discovered that existing electronic atomization devices usually use a constant power or constant voltage output method to make the temperature of the heating element reach a predetermined temperature, thereby heating and atomizing the atomization matrix. Since the boiling points of the flavor substances and non-flavor substances in the atomization matrix are different, the preset temperature generally takes the higher boiling point of the two as the preset temperature. Although this heating method can quickly atomize the flavor substances and non-flavor substances in the atomization matrix, due to the large amount of atomization and precipitation of the flavor substances in the atomization matrix, the user's aroma and taste will gradually fade as the number of puffs increases. The existing heating method cannot effectively control the atomization and precipitation amount of the flavor components, and the atomization effect is poor, and the user experience is not good.

[0031] To this end, the present application provides a method for controlling the heating of an electronic atomization device, see Figure 1 and 2, Figure 1 This is a schematic flow chart of a method for controlling heating of an electronic atomization device provided in one embodiment of the present application. Figure 2 The corresponding relationship diagram between the current puffing time and the temperature provided in this application, the heating control method of the electronic atomization device includes:

[0032] Step S1: In response to receiving a suction signal, the heating element is controlled to heat the substrate to be atomized based on a first control signal so that the temperature of the heating element reaches a first preset temperature, wherein the first preset temperature is the highest boiling point temperature of the flavor substance in the substrate to be atomized.

[0033] Specifically, the electronic atomization device is generally provided with airflow detection elements, heating elements, controllers and other components. When the user draws on the electronic atomization device, the airflow detection element detects the airflow change in the electronic atomization device and generates a puff signal. In response to receiving the puff signal, the controller outputs a first control signal S1 to the heating element so that the temperature of the heating element reaches a first preset temperature H1. The first preset temperature H1 is the highest boiling point temperature of the flavor substance in the matrix to be atomized, so as to fully heat the flavor substances of each component in the matrix to be atomized.

[0034] Specifically, the boiling point temperature range of the flavor substances in the matrix to be atomized is generally about 270-300 degrees Celsius, and the boiling point temperature range of the non-flavor substances is generally about 260-270 degrees Celsius. By setting the first preset temperature H1 to about 300 degrees Celsius, in the early stage of the entire inhalation process, the flavor substances in the matrix to be atomized can be heated and atomized so that the generated aerosol has a certain aroma, and the non-flavor substances in the matrix to be atomized can also be heated and atomized to ensure that the atomization amount of the generated aerosol is sufficient.

[0035] It should be pointed out that, during the preparation stage of the matrix to be atomized provided in the present application, the lowest boiling point temperature of the flavor substance in the matrix to be atomized is selected to be greater than the highest boiling point temperature of the non-flavor substance.

[0036] Step S2: After the temperature of the heating element reaches the first preset temperature, the heating element is controlled based on the second control signal to heat the substrate to be atomized within a first preset time period so that the temperature of the heating element is between the first preset temperature and the second preset temperature, wherein the second preset temperature is the lowest boiling point temperature of the flavor substance in the substrate to be atomized.

[0037] Specifically, in order to ensure that the aerosol generated after the atomized matrix is ​​atomized has a fragrance of a certain concentration and duration, after the temperature of the heating element reaches the first preset temperature H1, the temperature of the heating element needs to be maintained between the highest boiling point temperature and the lowest boiling point temperature of the flavor substance for a certain time, so that the concentration of the flavor substance in the aerosol reaches the preset concentration requirement. Therefore, the controller controls the temperature of the heating element to be between the first preset temperature H1 and the second preset temperature H2 within the first preset time period T1, so that the fragrance generated by the atomization of the flavor substance has a certain concentration and duration.

[0038] In addition, since the boiling point temperature range of the flavor substance is generally around 270-300 degrees Celsius, it takes a certain amount of time to reduce from the highest boiling point temperature to the lowest boiling point temperature. By controlling the output power of the heating element, the time for the temperature of the heating element to reduce from the highest boiling point temperature of the flavor substance to the lowest boiling point temperature is the first preset time period T1. Within the first preset time period T1, the heating element can still atomize the flavor substance, so that the aerosol generated after the atomized matrix is ​​atomized has a certain concentration of fragrance.

[0039] Step S3: After the heating element heats the substrate to be atomized within the first preset time period, the heating element is controlled to heat the substrate to be atomized based on a third control signal so that the temperature of the heating element is maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the substrate to be atomized.

[0040] Specifically, after the heating element heats the substrate to be atomized within the first preset time period T1, the generated aerosol has a certain aroma that can meet the user's taste requirements. In order to prevent the flavoring substance in the substrate to be atomized from being heated and atomized during the entire suction process, resulting in excessive precipitation of the flavoring substance, the controller outputs a third control signal S3 to control the heating element so that the temperature of the heating element is maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavoring substance in the substrate to be atomized, that is, the temperature of the heating element is lower than the lowest boiling point temperature of the flavoring substance in the substrate to be atomized. Among them, the highest boiling point temperature of the non-flavoring substance is the third preset temperature H3, and the lowest boiling point temperature of the non-flavoring substance is the fourth preset temperature H4.

[0041] By maintaining the temperature of the heating element between the third preset temperature H3 and the fourth preset temperature H4, the flavor substance in the matrix to be atomized cannot be heated and atomized by the heating element within the range of the third preset temperature H3 and the fourth preset temperature H4, thereby avoiding excessive consumption of the flavor substance in the matrix to be atomized.

[0042] It is understandable that the time it takes for a user to take a puff of the electronic atomization device is generally maintained at about 3-5s. To ensure the atomization effect, after the temperature of the heating element drops to the range of the third preset temperature H3 and the fourth preset temperature H4, the controller outputs a third control signal S3 to control the temperature of the heating element to maintain in the range of the third preset temperature H3 and the fourth preset temperature H4, to ensure that during the puffing process, the heating element can continue to heat the atomized non-flavor substance to produce an aerosol for the user to inhale, but the flavor substance in the matrix to be atomized is not consumed in this process, so that the flavor substance can act on the user's puffing process for a long time, avoiding the flavor substance in the matrix to be atomized from being consumed too quickly while a certain content of non-flavor substance is still present, affecting the user's subsequent puffing experience.

[0043] In one embodiment, a detection unit is further provided in the electronic atomization device, and the detection unit is used to detect the concentration of flavor substances in the aerosol. When the concentration of flavor substances in the aerosol detected by the detection unit reaches a preset threshold, the controller outputs a third control signal S3 so that the temperature of the heating element is between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substances in the matrix to be atomized.

[0044] In another embodiment, the controller outputs a third control signal S3 after the first preset time period T1, controlling the temperature of the heating element to be between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized. For example, during the 0.6-1 second period when the user draws on the electronic atomization device, the controller controls the temperature of the heating element to be between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized.

[0045] Specifically, the heating control method of the electronic atomization device provided in the present application has a control process divided into at least three stages: in the first stage Q1, the heating element is allowed to reach the first preset temperature H1 first to heat the flavor substance in the matrix to be atomized to generate an aerosol with fragrance; in the second stage Q2, the power output is reduced to control the temperature of the heating element to be between the first preset temperature H1 and the second preset temperature H2 in the first time period T1, so that the aerosol generated after the matrix to be atomized is atomized has a fragrance of a certain concentration and duration; in the third stage Q3, the temperature of the heating element is between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized, and the heating element only heats the atomized non-flavor substance, thereby preventing excessive precipitation of the flavor substance; reducing the waste of flavor substances, ensuring that the flavor substances have a certain concentration every time the user draws on the electronic atomization device, and improving the user experience.

[0046] In one embodiment, step S1 includes: based on a first control signal, controlling the heating element to operate at a constant first power so that the temperature of the heating element reaches a first preset temperature.

[0047] Specifically, the value range of the first power P1 is 6-12W, and the controller uses a constant first power P1 in the first stage Q1 to make the temperature of the heating element reach the first preset temperature H1. For example, the first power P1 can be 6W, 8W, 10W or 12W. Figure 3 , which is a corresponding relationship diagram between the current puff time and the output power of the electronic atomization device provided in one embodiment of the present application. Based on the first control signal S1, the controller outputs a constant first power P1 of 8.5W in the 0th to 0.1s of the current puff, thereby controlling the temperature of the heating element to reach the first preset temperature H1.

[0048] In another embodiment, step S1 includes: based on the first control signal, controlling the first power of the heating element to increase linearly so that the temperature of the heating element reaches a first preset temperature.

[0049] Specifically, the value range of the first power P1 is 6-12W, and the controller uses the linearly increasing first power P1 in the first stage Q1 to make the temperature of the heating element reach the first preset temperature H1. Figure 4 , which is a corresponding relationship diagram between the current puff time and the output power of the electronic atomization device provided in another embodiment of the present application. Based on the first control signal S1, the controller linearly increases the first power P1 output from 6W to 8W within 0.05-0.3s of the current puff, thereby controlling the temperature of the heating element to reach the first preset temperature H1.

[0050] In yet another embodiment, step S1 includes: based on the first control signal, controlling the first power of the heating element to increase in a stepwise manner so that the temperature of the heating element reaches a first preset temperature.

[0051] Specifically, the value range of the first power P1 is 6-12W, and the controller uses the first power P1 with a step-by-step increase in the first stage Q1 to make the temperature of the heating element reach the first preset temperature H1. Figure 5 , which is a corresponding relationship diagram between the current puffing time and the output power of the electronic atomization device provided in another embodiment of the present application, the controller increases the first power P1 output from 6W to 8W in a step-by-step manner at the 0th to 0.55th second of the current puffing based on the first control signal S1, thereby controlling the temperature of the heating element to reach the first preset temperature H1. Among them, the value range of the first difference A1 between the Nth first power P1 and the N-1th first power P1 is 0.5-1W, which can be selected according to actual conditions. It can be understood that if the value of the first difference A1 is large, the time for the temperature of the heating element to reach the first preset temperature H1 is faster, and if the value of the first difference A1 is small, the time for the temperature of the heating element to reach the first preset temperature H1 is slower.

[0052] In one embodiment, step S2 includes: based on the second control signal, controlling the second power of the heating element to decrease stepwise within a first preset time period so that the temperature of the heating element is between the first preset temperature and the second preset temperature.

[0053] Specifically, the controller uses the second power P2 which decreases in a stepwise manner in the second stage Q2 so that the temperature of the heating element is between the first preset temperature H1 and the second preset temperature H2. Figure 3 Based on the second control signal S2, the controller outputs a second power P2 from 8.5W to 6.5W in a stepwise manner at the 0.1-0.55s of the current puff, thereby controlling the temperature of the heating element to decrease from the first preset temperature H1 to the second preset temperature H2. Figure 4 , based on the second control signal S2, the controller outputs a second power P2 in a step-by-step manner from 8W to 6.5W at the 0.3-0.8s of the current puff, thereby controlling the temperature of the heating element to drop from the first preset temperature H1 to the second preset temperature H2. Among them, the value range of the second difference A2 between the Nth second power P2 and the N-1th second power P2 is 0.5-1W, which can be selected according to actual conditions. It can be understood that if the value of the second difference A2 is large, the faster the time for the temperature of the heating element to drop from the first preset temperature H1 to the second preset temperature H2, the shorter the time of the first preset time period T1; if the value of the first difference A1 is small, the slower the time for the temperature of the heating element to drop from the first preset temperature H1 to the second preset temperature H2, the longer the time of the first preset time period T1.

[0054] In one embodiment, the controller can control the size of the second difference A2 by detecting the concentration of the flavor substance in the aerosol detected by the detection unit, thereby controlling the time that the temperature of the heating element is maintained between the first preset temperature H1 and the second preset temperature H2, so that the generated aerosol has a certain concentration of fragrance.

[0055] In another embodiment, step S2 includes: based on the second control signal, controlling the second power of the heating element to decrease linearly within a first preset time period so that the temperature of the heating element is between the first preset temperature and the second preset temperature.

[0056] Specifically, the controller uses the linearly decreasing second power P2 in the second stage Q2 to make the temperature of the heating element between the first preset temperature H1 and the second preset temperature H2. Figure 5 Based on the second control signal S2, the controller linearly decreases the second power P2 output from 8W to 6.5W at 0.55-0.7s of the current puff, thereby controlling the temperature of the heating element to decrease from the first preset temperature H1 to the second preset temperature H2.

[0057] Specifically, in the heating control method of the electronic atomization device provided in the present application, the first stage Q1 and the second stage Q2 are basically maintained for a total of about 0.5-0.8s. During this time period, it can be ensured that the aerosol generated after the atomization matrix is ​​atomized has a certain concentration of fragrance, thereby ensuring the user experience.

[0058] In one embodiment, step S3 includes: based on a third control signal, controlling the third power of the heating element to switch between at least two sub-powers so that the temperature of the heating element is maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized within a second preset time period.

[0059] Specifically, the value range of the third power P3 is 4-7W, and the third power P3 uses two sub-powers of different powers to be output alternately, so that after the temperature of the heating element is reduced from the first preset temperature H1 to the second preset temperature H2, the temperature of the heating element is maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized within the second preset time period T2. Among them, the temperature of the heating element is maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized within the second preset time period T2, which can ensure that the heating element can fully heat the non-flavor substance to generate aerosol of a certain concentration, and ensure the user's satisfaction with the aerosol generated by the non-flavor substance in the atomized matrix.

[0060] See also Figure 3 , Figure 4 and Figure 5In the embodiment of the present application, the two sub-powers are 6.5W and 6W respectively, one of which is lower and less than the average power of the third power P3, which will cause the temperature of the heating element to drop; while the other sub-power is higher and higher than the average power of the third power P3, which will cause the temperature of the heating element to rise. By alternating the output of two sub-powers of different powers, the temperature of the heating element in the third stage Q3 is maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized.

[0061] See also Figure 6 , is a flow chart of a method for controlling heating of an electronic atomization device provided by another embodiment of the present application, which further includes after steps S1-S3:

[0062] Step S4: After the second preset time period, in response to the continued existence of the inhalation signal, the heating element is controlled to operate at a constant fourth power based on a fourth control signal, and the fourth power is less than the minimum sub-power of at least two sub-powers of the third power, so that the temperature of the heating element continues to be maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized.

[0063] Specifically, the second preset time period T2 may be 3s or 4s. For example, the second preset time period T2 is 3s. Since the time for a user to take a puff of the electronic atomization device is generally maintained at about 3-5s, after 3s of the user taking a puff of the electronic atomization device, it is basically at the end of this puff. If the controller maintains a high power output, part of the generated aerosol may not be sucked out of the electronic atomization device by the user, resulting in waste. In addition, the aerosol that is not sucked out will form condensate, blocking the airway of the electronic atomization device, which may cause the electronic atomization device to be unusable in severe cases. Therefore, after the second preset time period T2 when the user takes the puff, the controller detects the continued existence of the puff signal through the airflow detection element, and outputs the fourth power P4 based on the fourth control signal to make the heating element operate at a constant fourth power P4, and the fourth power P4 is less than the minimum sub-power of at least two sub-powers of the third power P3, and the value range of the fourth power P4 is 4-5W, so that the temperature of the heating element continues to be maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized, specifically, the temperature of the heating element is maintained at about the lowest boiling point temperature of the non-flavor substance.

[0064] See also Figure 3 , Figure 4 and Figure 5In this embodiment of the present application, the fourth power P4 is 4.5W. Specifically, the controller outputs the fourth power P4 based on the fourth control signal to ensure that the temperature of the heating element is maintained at the low boiling point temperature of the non-flavor substance, thereby reducing the amount of aerosol that is heated and atomized by the substrate to be atomized, avoiding the waste of the substrate to be atomized and the formation of condensate.

[0065] The heating control method of the electronic atomization device provided in the present application has a control process divided into four stages: the first stage Q1 allows the heating element to reach the first preset temperature H1 first to heat the flavor substance in the matrix to be atomized and generate an aerosol with fragrance; the second stage Q2 reduces the power output and controls the temperature of the heating element to be between the first preset temperature H1 and the second preset temperature H2 in the first time period T1, so that the aerosol generated after the matrix to be atomized has a certain concentration and duration of fragrance; the third stage Q3 makes the temperature of the heating element between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance in the matrix to be atomized, and the heating element only heats the atomized non-flavor substance, thereby preventing the excessive precipitation of the flavor substance; reducing the waste of flavor substances, ensuring that the flavor substances have a certain concentration every time the user draws the electronic atomization device, and improving the user experience. The fourth stage Q4 further reduces the power output so that the temperature of the heating element is maintained between the highest boiling point temperature and the lowest boiling point temperature of the non-flavor substance, avoiding the waste of the matrix to be atomized and the formation of condensate, and improving the user experience.

[0066] See also Figure 7 , is a schematic diagram of the structure of an electronic atomization device provided in an embodiment of the present application, wherein the electronic atomization device 10 comprises a heating element 11 and a battery assembly 12, wherein the heating element 11 is used to heat and atomize the substrate to be atomized, for example, the solid substrate to be atomized of plant leaves with a specific aroma is baked in a heating-not-burning manner so that the solid substrate to be atomized of the leaves is baked to form an aerosol, and further, the solid substrate to be atomized of plant leaves can be added with flavoring substances, and heated and mixed in the aerosol at the same time, so that the aerosol has the desired aroma.
