Description

Technical Field

[0001] This application relates to the field of aerosol generation technology, and particularly to aerosol generation apparatus. Background Technology

[0002] The aerosol generator contains an internal airflow sensor. This sensor detects changes in air pressure and triggers a controller on the circuit board to activate the atomizing component, which then atomizes the liquid matrix into an aerosol for the user to inhale. In some existing designs, one end of the airflow sensor is connected to atmospheric pressure through an air vent or charging port on the housing, while the other end is sealed with an O-ring or sealing silicone sealant on the battery holder and connected to the airflow channel inside the aerosol generator. This allows the airflow sensor to detect different air pressures on both sides during inhalation and output a trigger signal. However, improper assembly and poor sealing when installing the O-ring on the battery holder can lead to poor suction resistance. Furthermore, the dimensional requirements for the housing and battery holder are relatively high, making it unsuitable for processing and assembling irregularly shaped housings, resulting in poor sealing of the airflow sensor.

Figure 1-3As shown, 10 includes: a housing 1, an atomizing assembly 2, a battery assembly 7, a first support 3, a circuit board assembly 4, a first seal 5, and an air guide tube 6. The housing 1 has a liquid storage chamber 11 for storing a liquid matrix and an aerosol channel 12 for aerosol passage. The atomizing assembly 2 is disposed within the housing 1 and is used to atomize the liquid matrix to generate an aerosol. The battery assembly 7 supplies power to the atomizing assembly 2. The first support 3 is disposed within the housing 1 and has a first air inlet 31 and a second air inlet 32 ​​spaced apart. Both the first air inlet 31 and the second air inlet 32 ​​communicate with the aerosol channel 12, and the first air inlet 31 provides air into the aerosol channel 12. The circuit board assembly 4 is disposed at the end of the battery assembly 7 away from the atomizing assembly 2, and has an airflow sensor 41. The first seal 51 at least partially surrounds or contains the airflow sensor 41, and has a first through hole 511 communicating with one side of the airflow sensor 41. The air duct 6 is positioned away from the battery assembly 7. One end of the air duct 6 is connected to the second air inlet 32, and the other end of the air duct 6 is connected to the first through hole 511.

[0044] The aerosol generating device 10 provided in this application is provided with an air guide pipe 6. One end of the air guide pipe 6 is connected to the second air inlet 32 ​​of the first bracket 3, and the other end of the air guide pipe 6 is connected to the first through hole 511 of the first sealing member 51. This makes the airflow sensor 41 have good sealing performance. The shape of the housing 1 does not need to be considered during the design. The shape of the housing 1 is varied. The sealing performance between the housing 1 and the first bracket 3 does not need to be considered during the assembly process, making the assembly convenient.

[0045] In one embodiment of this application, the aerosol generating device 10 further includes a suction nozzle disposed at one end of the housing 1. The housing 1 includes a first snap-fit ​​portion, and the suction nozzle includes a second snap-fit ​​portion.

Based on the different properties of the liquid matrix, aerosol matrix reservoirs can be used in different fields, such as medical and electronic aerosol atomization.

[0047] In one embodiment of this application, there are two aerosol channels 12, located on opposite sides of the liquid storage chamber 11. In another embodiment of this application, the nozzle includes a guide portion, which is arc-shaped.

Part of the air entering from the air vent 13 passes through the battery housing cavity 34 and enters the aerosol channel 12 through the first air inlet 31, while the other part enters the air guide tube 6 through the second air inlet 32, thereby causing a change in air pressure at one end of the airflow sensor 41, triggering the airflow sensor 41, and the controller on the circuit board assembly 4 controls the atomizing assembly 2 to start working.

[0054] In one embodiment of this application, such as Figure 4-5 As shown, the first support 3 defines a battery receiving cavity 34 for receiving the battery assembly 7. An air path is provided between the housing 1 and the battery assembly 7 and / or the first support 3. The battery assembly 7 is connected to an electrode post via a wire, and the electrode post abuts against the atomizing assembly 2, thereby electrically connecting the battery assembly 7 and the atomizing assembly 2.

[0055] In one embodiment of this application, the air duct 6 is airtightly isolated from the air path, and there is no need to consider the sealing between the housing 1 and the first bracket 3 during the assembly process, making assembly convenient.

[0056] In one embodiment of this application, the atomizing component 2 includes a ceramic core and a heating element, the heating element being either patched or printed onto the ceramic core. In one embodiment of this application, the aerosol generating device 10 includes an electrode post, one end of which abuts against the heating element, and the other end of which passes through a wire connected to the battery assembly 7 via the first bracket 3. In one embodiment of this application, the first bracket 3 has a mounting hole 33 through which the electrode post passes. In one embodiment of this application, the second sealing member 52 has a third through hole 522 through which the electrode post can pass.

[0057] In one embodiment of this application, the air guide tube 6 and the first through hole 511 are interference-fitted. In another embodiment of this application, the air guide tube 6 and the second air inlet 32 ​​are interference-fitted.
