Description

Technical Field

[0001] The utility model relates to the technical field of electronics, and particularly relates to an atomization component and an aerosol generating device. Background Art

[0002] Currently, the common way to count the number of times a user sucks the aerosol in the atomization component is usually to set an airflow sensor or a pressure sensor in the atomization component to count the number of puffs of the user on the atomization component by using the airflow sensor or the pressure sensor. However, since there are more openings on one side of some atomization components and fewer openings on the other side, the distribution of the airflow in the atomization component is extremely uneven (for example, the change in the airflow around the airflow sensor or the pressure sensor is small or there is no change at all when the user sucks), and thus it is easy to cause the airflow sensor or the pressure sensor to be unable to effectively count the number of puffs of the user on the atomization component.

[0023] The technical solution of the present application will be described in detail below in conjunction with the embodiments.

[0024] The present application provides an atomization assembly. The atomization assembly includes:

[0025] A receiving cavity for receiving an aerosol-forming substrate;

[0026] A heating element for heating the aerosol-forming substrate to generate an aerosol for user inhalation;

[0027] An air passage having an air inlet port and an air outlet port, and air enters through the air inlet port and exits through the air outlet port when the user inhales;

[0028] A suction detection assembly including an infrared emitter and an infrared receiver disposed opposite to each other. The infrared emitter and the infrared receiver are disposed in the air passage or the receiving cavity. The infrared emitter is used to emit an infrared signal towards the infrared receiver, and the infrared receiver is used to receive the infrared signal and detect the change in the intensity of the infrared signal.

[0029] The infrared receiver can detect the change in the intensity of the infrared signal, and thus can obtain the number of times the user inhales the aerosol at the end of the second sub-airway away from the accommodation cavity.

[0030] In some embodiments, the above airway can store the aerosol.

[0031] In some embodiments, the airway includes a first sub-airway, a second sub-airway, and an accommodation cavity. The accommodation cavity is disposed between the first sub-airway and the second sub-airway. The suction detection component is disposed in the first sub-airway.

[0032] In some embodiments, the accommodation cavity, the second sub-airway, and the first sub-airway can all store the aerosol.

[0033] In some embodiments, the second sub-airway and the first sub-airway can store the aerosol.

[0034] In some embodiments, the technical concept of the present application is: Please refer to Figure 1 , the airway includes a first sub-airway 31 and a second sub-airway ( Figure 1 not shown in ); an infrared emitter 41 and an infrared receiver 42 are disposed in the first sub-airway 31 of the atomization component. When the user inhales the aerosol formed matrix or the air outlet port 62 accommodated in the accommodation cavity 10, since the external air enters the first sub-airway 31 from the air inlet port 61 of the atomization component, the concentration of the aerosol in the airway (such as the first sub-airway 31) and the accommodation cavity 10 decreases, and thus the intensity (or the number of infrared signals) of the infrared signal received by the infrared receiver 42 increases, so as to detect whether there is a suction action.

[0035] In some embodiments, the infrared emitter 41 and the infrared receiver 42 can also be disposed in the accommodation cavity 10.

[0036] In some embodiments, the aerosol can only be discharged to the outside of the atomization component through the second sub-airway.

[0037] Those skilled in the art can determine the shape and size of the accommodation cavity according to actual needs, and the shape and size thereof are not limited herein. For example, the accommodation cavity can be cylindrical.

[0038] Those skilled in the art can determine the type of the aerosol forming matrix according to actual needs. For example, the aerosol forming matrix can include at least one aerosol forming agent. An aerosol forming agent is any suitable known compound or mixture of compounds that facilitates the formation of a thick and stable aerosol during use and is substantially resistant to thermal degradation at a certain temperature. Since the specific type of the aerosol forming matrix is common general knowledge in the art, the specific composition of the aerosol forming matrix will not be described in detail herein.

[0039] It can be understood that, please refer to Figure 1, the user can obtain the aerosol in the second sub-airway by sucking the aerosol-forming substrate or the air outlet port 62 accommodated in the accommodation cavity 10.

[0040] In some embodiments, please refer to Figure 1 , the infrared emitter 41 and the infrared receiver 42 are oppositely arranged on the inner wall of the first sub-airway 31.

[0041] In some embodiments, the infrared emitter and the infrared receiver are oppositely arranged on the inner wall of the second sub-airway.

[0042] In some embodiments, the infrared emitter and the infrared receiver are oppositely arranged on the inner wall of the accommodation cavity, wherein the aerosol-forming substrate in the accommodation cavity cannot be arranged on the emission path of the infrared signal to prevent the infrared signal from not being received by the infrared receiver.

[0043] It should be noted that both the infrared emitter and the infrared receiver are existing technologies in the art, so the principles and specific structures of the infrared emitter and the infrared receiver will not be elaborated here.

[0044] In some embodiments, there is a preset distance perpendicular to the flow direction of the aerosol between the infrared emitter and the second infrared emitter.

[0045] Those skilled in the art can determine the preset distance according to actual needs. For example, the preset distance can be equal to the inner diameter of the first sub-airway or the inner diameter of the second sub-airway.

[0046] In some embodiments, please refer to Figure 1 , one end of the accommodation cavity 10 is hermetically connected to the first sub-airway 31. The other end of the accommodation cavity 10 is hermetically connected to the second sub-airway.

[0047] In some embodiments, please refer to Figure 1 , the airway further includes an air inlet port 61 and an air outlet port 62; wherein, the air inlet port 61 is used to connect the first sub-airway 31 to the outside of the atomization component; the air outlet port 62 is used to connect the second sub-airway to the outside of the atomization component.

[0048] In some embodiments, the air inlet port 61 is integrally connected to the end of the first sub-airway 31 far from the accommodation cavity 10.

[0049] In some embodiments, the air inlet port 61 is detachably connected to the end of the first sub-airway 31 far from the accommodation cavity 10.

[0050] In some embodiments, the air outlet port 62 is integrally connected to the end of the second sub-airway far from the accommodation cavity 10.

[0051] In some embodiments, the air outlet port 62 is detachably connected to the end of the second sub-airway far from the accommodation cavity 10.

[0052] In some embodiments, a one-way valve is provided in the first sub-airway, and the one-way valve is used to prevent the aerosol from being discharged from the intake port to the outside of the atomization assembly.

[0053] In some embodiments, the suction detection assembly includes an infrared emitter and an infrared receiver that are oppositely arranged. The infrared emitter and the infrared receiver are located between the one-way valve and the accommodation chamber.

[0054] In some embodiments, please refer to Figure 1 , when the user does not suck the aerosol in the second sub-airway through the aerosol formation matrix or the air outlet port 62 accommodated in the accommodation chamber 10, the aerosol generated by heating the aerosol formation matrix in the accommodation chamber 10 by the heating element 20 can enter the first sub-airway 31 and the second sub-airway; when the user sucks the aerosol in the second sub-airway through the aerosol formation matrix or the air outlet port 62 accommodated in the accommodation chamber 10, the aerosol generated by heating the aerosol formation matrix by the heating element 20 and the aerosol in the first sub-airway 31 both flow to the second sub-airway.

[0055] In some embodiments, the controller is further configured to record the number of suction times according to the intensity change of the infrared signal detected by the suction detection assembly.

[0056] In some embodiments, please refer to Figure 1, when the heating element 20 heats the aerosol-forming substrate in the accommodation cavity 10 and the user does not suck the aerosol in the second sub-airway through the aerosol-forming substrate or the air outlet port 62 accommodated in the accommodation cavity 10, the aerosol generated by the aerosol-forming substrate will gradually diffuse throughout the airway, that is, the accommodation cavity 10, the first sub-airway 31 and the second sub-airway. In some embodiments, the above aerosol can even fill the entire airway. Since the aerosol partially fills or fills the first sub-airway 31, especially the space between the infrared emitter 41 and the infrared receiver 42, the intensity of the infrared signal received by the infrared receiver 42 gradually decreases. When the user sucks the aerosol in the second sub-airway through the aerosol-forming substrate or the air outlet port 62 accommodated in the accommodation cavity 10, due to the negative pressure in the second sub-airway, the external air will enter the first sub-airway 31 through the air inlet port 61, and the aerosol in the first sub-airway 31 will be sucked towards the second sub-airway together with the air entering the first sub-airway 31, and finally be inhaled into the user's mouth through the aerosol-forming substrate or the air outlet port 62 accommodated in the accommodation cavity 10. At this time, the intensity of the infrared signal received by the infrared receiver 42 gradually increases. Therefore, the start of the decrease in the intensity of the infrared signal received by the infrared receiver 42 can be used as the starting mark for the user to complete a complete suction action; and the end of the increase in the intensity of the infrared signal received by the infrared receiver 42 can be used as the end mark for the user to complete a complete suction action, that is, the time period from the start of the decrease in the intensity of the infrared signal received by the infrared receiver 42 to the end of its increase can be used as the time for the user to complete a complete suction action. And this time can be used to effectively count the number of times the user sucks the aerosol in the atomization component.

[0057] It should be noted that the principle of the infrared receiver to obtain the number of times the user sucks the aerosol can refer to the working principle of existing smoke alarms.

[0058] It should be noted that the specific determination process of the above "time period from the start of the decrease in the intensity of the infrared signal received by the infrared receiver to the end of its increase" belongs to the common knowledge in the art, so the specific process of the infrared receiver to determine the "time for the user to complete a complete suction action" will not be described here.

[0059] In some embodiments, the atomization component further includes a controller. The controller is used to adjust the energy input to the heating element according to a preset power-time relationship curve, so as to increase the temperature of the heating element, and then heat the aerosol-forming substrate in the accommodation cavity through the heating element.

[0060] In some embodiments, the controller may further be configured to adjust the power output to the heating element according to the change in the intensity of the infrared signal detected by the suction detection component. For example, the temperature of the heating element is adjusted by using the time period during which the infrared rays received by the infrared receiver start to decrease and then increase in number and / or the magnitude of the intensity change, that is, the power output to the heating element is adjusted. Furthermore, after the user completes a complete suction action, the controller can calculate the value of the energy to be replenished to the heating element, thereby preparing for the user to complete the next complete suction action. It should be noted that those skilled in the art can specifically determine the value of the energy to be replenished to the heating element according to actual needs or actual production experience. For example, it can be determined according to the ratio of the above-mentioned time period to a reference time (such as five seconds): for example, if the above-mentioned time period is equal to the reference time, the power output to the heating element can be adjusted to replenish one unit of energy to the heating element (those skilled in the art can set the magnitude of one unit of energy by themselves); if the above-mentioned time period is equal to twice the reference time, the power output to the heating element can be adjusted to replenish two units of energy to the heating element. For another example, the ratio of the intensity change to a preset intensity change reference value can also be taken into account, that is, if the above-mentioned time period is equal to the reference time and the ratio of the intensity change to the preset intensity change reference value is also equal to 1, the power output to the heating element can be adjusted to replenish one unit of energy to the heating element; if the above-mentioned time period is equal to twice the reference time and the ratio of the magnitude of the intensity change to the preset intensity change reference value is equal to 1 / 2, the power output to the heating element can be adjusted to replenish one unit of energy to the heating element.

[0061] In some embodiments, a cooling section is provided in the second sub-airway. The cooling section is used to reduce the temperature of the aerosol.

[0062] In some embodiments, a filtering section is provided in the second sub-airway. The filtering section is used to filter solid particles in the aerosol. For example, filter cotton can be filled in the filtering section to filter solid particles in the aerosol.

[0063] It should be noted that the specific settings of the cooling section and the filtering section both belong to the prior art in this field, so they will not be elaborated here.

[0064] It can be seen that in some embodiments, in the atomization component of the present application, by arranging the infrared emitter and the infrared receiver in the airway or the accommodation cavity, the infrared emitter is used to emit infrared signals towards the infrared receiver, and the infrared receiver is used to receive the infrared signals and detect the change in the intensity of the infrared signals to obtain the number of times the user sucks the aerosol at the end of the second sub-airway away from the accommodation cavity. That is, the atomization component of the present application can effectively count the number of puffs of the user on the atomization component.

[0065] It can be seen that in some embodiments, the capacity and intensity of the user's inhalation of the aerosol can be determined according to the change in the intensity of the infrared signal received by the infrared receiver (such as the amount of intensity reduction), providing the possibility for further intelligent adjustment of the temperature of the heating element.
