Description

Aerosol generating device

The embodiments relate to an aerosol generating device, and more particularly, to an aerosol generating device capable of generating a high-quality aerosol.

In recent years, there is an increasing demand for alternative methods to overcome the shortcomings of general cigarettes. For example, there is an increasing demand for a method of generating an aerosol by heating an aerosol-generating material rather than a method of generating an aerosol by burning a cigarette.

Korean Patent Application Publication No. 10-2015-0030733 describes a vaporizer that generates steam by using a heating element disposed on a passage through which air flows. In such a vaporizer, the contact time between the heating element and the air is very short, and it is difficult to generate a large amount of steam.

Korean Patent Publication No. 10-1949064 describes an aerosol generating system having a passage for introducing outside air into a heater. In such an aerosol generating system, external air introduced to the heater through the passage is discharged to the outside after only contacting the heater for a short time. For this reason, the contact time between the heater and air is very short, making it difficult to generate a large amount of steam.

Korean Patent Publication No. 10-1969566 describes a cigarette inhalation device in which a spiral airflow is applied to a part of a nozzle section that transmits steam generated from a nebulizer to a user. The spiral airflow of such a cigarette inhaler does not participate in the operation of the atomizer generating steam, but only serves to promote mixing of the steam generated from the atomizer and the smoke generated from the heated cigarette. Therefore, in the process of generating steam by the atomizer, it is difficult to generate a large amount of steam because the air introduced from the outside contacts the heater for only a short time.

The liquid delivery means 111 is connected to the upper wall 135. Both ends of the liquid delivery means 111 pass through the upper wall 135 and remain in contact with the aerosol-generating material 160. The liquid delivery means 111 maintains a state in which the aerosol-generating material 160 is absorbed, so when heat is generated by the heater 110 surrounding the liquid delivery means 111, the liquid delivery means 111 absorbs and holds The aerosol-generating material 160 is vaporized to generate an aerosol.

Arrangement positions and structures of the heater 110 and the liquid delivery means 111 shown in FIG. 5 are exemplary and may be variously modified. For example, the heater 110 may be disposed adjacent to the liquid delivery means 111 without being wound around the liquid delivery means 111. In addition, the structure of the liquid delivery means 111 can be transformed into a mesh shape or a plate shape, and the heater 110 and the liquid delivery means 111 can be integrated into one component. Yes (for example, it may be implemented as a metal mesh heater).

Since the air introduced into the case 100 from the outside of the case 100 through the delivery passage 122 is supplied to the heating passage 121, the air is transferred to the heating passage 121 with the liquid delivery means 111 and the heater. An atmosphere in which the aerosol and air generated from the liquid delivery means 111 can be naturally mixed is created around the 110.

A terminal 110c is installed at the lower end of the case 100. The terminal 110c is installed to be exposed from the bottom of the case 100 to the outside so as to be electrically connected to the power supply unit on the main body side. The terminal 110c performs a function of transferring electricity supplied from the main body to the heater 110.

The plurality of contact holding portions 130 formed on each of the upper wall 135 and the lower wall 136 may be formed at positions corresponding to each other with the heater 110 interposed therebetween.

Since the upper wall 135 and the lower wall 136 forming the heating passage 121 include a plurality of contact holding portions 130, the time for the air to stay in the heating passage 121 may increase.

Assuming that the contact holding unit 130 is not installed on the upper wall 135 and the lower wall 136, the air introduced into the heating passage 121 through the delivery passage 122 is not affected by the user's suction operation.

Due to this action, a sufficient time for contact between the air and the heater 110 in the heating passage 121 is not secured, and the air is immediately discharged to the outside of the case 100, so that the air in contact with the heater 110 is generated. It is not possible to form an atmosphere of sufficiently heated temperature for this. As a result, the aerosol generated by the heating action of the heater 110 is not sufficiently heated, so that the aerosol is converted into droplets (liquid droplets) while in contact with air of a relatively low temperature.

However, according to the aerosol generating apparatus according to the above-described embodiment, the contact holding unit 130 confines and holds the air around the heater 110 in the heating passage 121, thereby preventing the flow of air existing around the heater 110. It can perform the action of stagnating or retarding some. For this reason, the temperature of the air around the heater 110 may be maintained at a sufficiently high temperature for generating an aerosol. 'Part of the air flow is stagnating' means that the air flow stops, or stops. Also,'part of the air flow is retarded' means that the air flow is slowed down and the speed is lowered.

In addition, since the contact holding unit 130 holds the air around the heater 110, the temperature of the heater 110 increases, and sufficient air is immediately supplied to the heater 110 while performing a heating action to generate an aerosol. Can be. As described above, since a sufficient amount for the generation of aerosol and air in an optimally heated state may be supplied to the heater 110, a high-quality aerosol may be generated.
