Description

Technical Field

[0001] The present application relates to the technical field of aerosol atomization, and in particular to an aerosol generating device. Background Art

[0002] An aerosol generating device is a device that heats liquid and atomizes it into an aerosol. It is widely used in the fields of medicine, industry, agriculture, scientific research, electronic cigarettes, etc.

[0003] Aerosol generating devices are usually of two types: a separate atomizing component and a combined atomizing component. In an atomizer with a separate atomizing component, the atomizing component needs to be activated before use. After activation, the atomizing component is connected to the oil storage space of the atomizer, and the aerosol generating oil can enter the atomizing component. When the atomizer is not in use, the atomizing component is isolated from the oil storage space, which can effectively prevent the aerosol generating oil from leaking from the atomizing channel of the atomizing component. However, in daily life, the current atomizer with a separate atomizing component is easily started by mistake when not in use, the electric heating element in the atomizing component is dry-burned, and the atomizing component is easily damaged.

[0004] In response to the above-mentioned problem of being mistakenly started, some aerosol generating devices set a switch element on the atomizer circuit to be linked with the isolation piece of the atomizer. The isolation piece can realize the conduction and isolation between the atomization channel and the oil storage space. When the isolation piece is in the isolation position, the switch element disconnects the atomizer circuit. At this time, the atomizer circuit will not be mistakenly started, the electric heating element cannot be started, and the atomizer is not prone to dry burning. When the isolation piece is in the conducting position, the switch element connects the atomizer circuit, which does not affect the normal operation of the atomizer. However, a linkage mechanism needs to be set between the switch element and the isolation piece. The setting of the switch element and the linkage mechanism increases the complexity of the structure and the cost is relatively high. Summary of the invention

The first oil inlet channel 41 is connected to the oil storage chamber 11, and the first air inlet channel 42 is connected to the outside atmosphere. The linkage component 4 has a conducting position and an isolating position during the movement.

[0064] When the linkage component 4 is in the conducting position, the first oil inlet channel 41 is connected to the atomizing channel 12, so that the aerosol-generated oil in the oil storage chamber 11 can enter the atomizing channel 12, and the first air inlet channel 42 is connected to the atomizing channel 12, so that the outside air can enter the atomizing channel 12;

[0065] When the linkage component 4 is in the isolation position, the first oil inlet channel 41 and the atomization channel 12 are separated by the blocking component 3 to prevent the aerosol-generated oil in the oil storage chamber 11 from entering the atomization channel 12, and the first air inlet channel 42 and the atomization channel 12 are separated by the blocking component 3 to prevent outside air from entering the atomization channel 12.

[0066] The aerosol generating device of the present invention integrates the first oil inlet channel 41 and the first air inlet channel 42 on the linkage component 4, and utilizes the cooperation of the linkage component 4 and the barrier component 3 to realize the connection and isolation between the oil storage chamber 11 and the atomization channel 12, and at the same time realizes the connection and isolation between the external atmosphere and the atomization channel 12; wherein, when the linkage component 4 is in the connection position, the first oil inlet channel 41 is connected to the atomization channel 12, so that the atomization channel 12 and the oil storage chamber 11 are connected through the first oil inlet channel 41, and the oil in the oil storage chamber 11 can enter the atomization channel 12 through the first oil inlet channel 41. At the same time, the first air inlet channel 42 is connected to the atomization channel 12, so that the atomization channel 12 and the external atmosphere are connected through the first air inlet channel 42, so that the external air can enter the atomization channel 12, so that the air pressure in the atomization channel 12 changes, and the air pressure sensor of the aerosol generating device senses the air pressure drop in the atomization channel 12, so that the atomization core 2 is controlled by the atomization core 2 circuit and starts During the heating operation, the atomizer core 2 heats and atomizes the oil entering the atomizer channel 12 to form an aerosol; when the linkage component 4 is in the isolation position, the first oil inlet channel 41 is not connected to the atomizer channel 12, so that the atomizer channel 12 is separated from the oil storage chamber 11 to prevent the aerosol-generated oil in the oil storage chamber 11 from entering the atomizer channel 12.

At this time, the atomizer core 2 circuit will not be mistakenly started, and the atomizer core 2 cannot be started. Based on the fact that the problem of the atomizer core 2 being mistakenly started can be avoided only through the cooperation of the blocking component 3 and the linkage component 4, fewer parts are required, the structure is simplified, and the cost can be reduced, which is more conducive to the promotion and application of the aerosol generating device.

[0067] See also Figure 4 and Fig.11 In one embodiment, the blocking component 3 has a connecting channel 31, a first sealing portion 32, a second sealing portion 33, an oil passage port 34 and an air passage port 35.
