Description
Technical Field
The invention relates to the technical field of atomization, in particular to an atomization device.
Background
As an aerosol is a colloidal dispersion system formed by dispersing and suspending small solid or liquid particles in a gaseous medium, the aerosol can be absorbed by a human body through a respiratory system, so that an atomization device for generating the aerosol by heating substances such as medical drugs or tobacco shreds can be applied to different fields such as medical treatment and tobacco substitute products, and the aerosol for inhalation can be delivered to users.
Taking a baking type atomization device as a cigarette substitute product as an example, the existing atomization device has two heating modes of a conduction heating mode and a hot air heating mode to bake and heat materials (such as cut tobacco).
The conduction heating mode is to heat the material in the heating container by the heat radiation principle, the optimal heat radiation radius is within 3-5mm, and the heat radiation efficiency is greatly reduced beyond the range, so that the material positioned in the center of the heating container cannot be thoroughly heated. If the temperature of the heating vessel is simply increased in order to increase the heat radiation radius, the material near the inner wall of the heating vessel will already burn out due to the too high temperature if the material in the central position has not reached the desired temperature. Therefore, the heating mode of conduction heating has a limitation that limits the capacity of the heating vessel.
The hot air heating mode mainly utilizes air preheating to heat to form hot air to heat the material in the heating container in an impact manner, so that the problem that the material in the central position of the heating container cannot be thoroughly heated is avoided. However, the air preheating takes a sufficient preheating time, and the conventional preheating time generally exceeds 60 seconds, thereby prolonging the heating time. Moreover, since the air heating is to heat the material by the impact of the hot air in one direction, there is no radiation heating, so that only the place through which the hot air passes can effectively heat the material, but other places around the periphery through which no air passes are not radiated, and therefore the material at the edge cannot be effectively heated.
Therefore, the heating mode of the conventional atomizing device cannot have the advantages of high heating speed and large heating range, so that the atomizing effect of the atomizing device is affected, and the use experience of a user is reduced.

In this way, the airflow channel is formed by dividing the airflow channel into a plurality of sub-airflow channels which are connected with each other, so that the flowing distance of the airflow in the airflow channel is prolonged, the airflow in the airflow channel can be fully heated, the temperature of the airflow entering the heating cavity 112 is higher, and the heating effect is effectively improved. Conversely, if the air flow passes through the air flow passage quickly, sufficient heating is not obtained, resulting in a lower temperature of the air flow entering the heating chamber 112, which affects the heating effect.
In particular, in some embodiments, the second heating assembly 30 includes a first flow guide 32 and a second flow guide 33 coaxially disposed with the heating cylinder 31, and the diameter of the first flow guide 32 is smaller than the diameter of the second flow guide 33, and the diameter of the second flow guide 33 is smaller than the diameter of the heating cylinder 31.

In particular, in one embodiment, the flow guide 34 is located in the third sub-airflow path between the heating cylinder 31 and the second flow guide 33. In this manner, the deflector 34 may direct the airflow to spiral, thereby further extending the flow length of the airflow.
In some embodiments, the atomizing device 100 further includes a first temperature sensing unit and a second temperature sensing unit coupled to the control unit 50, respectively.

Specifically, in one embodiment, the heat output from the first heating element 10 is 10% and the heat output from the second heating element 30 is 90%. In another embodiment, the heat output from the first heating assembly 10 is 40% and the heat output from the second heating assembly 30 is 60%. It will be appreciated that the specific values of the heat duty cycle of the first heating element 10 and the second heating element 30 are not limited, and may be set as required to meet different requirements.
Further, in some embodiments, under the control of the control unit 50, the atomizing device 100 may first be in a conduction heating mode to rapidly extract a desired substance in the material, and then be switched to a hot air heating mode to heat the remaining additive material to further extract the desired substance. Specifically, the atomizing device 100 is in the conduction heating mode for the first two minutes during heating, and then switches to the hot air heating mode.
In other embodiments, the atomizing device 100 can be switched between the conduction heating mode and the hot air heating mode rapidly, so that the problem that the material center cannot be heated effectively in a single conduction heating mode is effectively solved, and the problem that the preheating time is too long and only the hot air current is impacted but no heat radiation is caused in a single hot air heating mode is solved. In particular, the single run time of each mode may be only a few seconds, thereby enabling a fast alternating switching of the two modes.
The above-mentioned atomizing device 100, because it is equipped with the first heating component 10 that adopts conduction heating mode to heat the material and the second heating component 30 that adopts hot air heating mode to heat the material simultaneously, can switch in different heating modes as required in order to realize the material heating, has combined the advantage of two kinds of atomizing modes, has great heating range when the intensification time is short. In addition, the output duty ratio of the two modes in the mixed heating mode can be adjusted according to the requirement, substances in different temperature stages can be effectively extracted, and the material utilization rate can be improved by more than 30%. In addition, in the case of the same space, the length of the air flow passage of the atomizing device 100 is significantly increased, thereby improving the energy utilization rate by more than 1 time.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
