The aerosol-generating substrate includes, but is not limited to, materials for medical, health, wellness, and cosmetic purposes, e.g., aerosol-generating substrates are medical fluids, oils, and the like.

The atomizing device 100 includes a housing 10, a battery 20, an atomizer 30, and an airflow sensor 40, and the atomizer 30, the battery 20, and the airflow sensor 40 are all disposed within the housing 10.

The atomizer 30 has an air intake passage 31, and the housing 10 is provided with an air intake hole 11, the air intake hole 11 communicating with the air intake passage 31. When a user inhales at the suction nozzle of the atomizer 30, external air enters the air inlet channel 31 from the air inlet hole 11, the air flow sensor 40 can detect the change of the air pressure in the air inlet channel 31, and the atomizer 100 can control the atomizer 30 to start heating according to the detection result of the air flow sensor 40.

The atomizer 30 has a reservoir 32, which reservoir 32 may be used to store a liquid aerosol-generating substrate. The atomizer 30 comprises an atomizing core 33, and the atomizing core 33 can guide the aerosol-generating substrate in the liquid storage bin 32 to the heating surface for heating so as to atomize the aerosol-generating substrate to generate atomized gas.

In some of these embodiments, the atomizer 30 further includes an atomization seat 34, the atomization seat 34 having an atomization chamber 36, the atomization chamber 36 being communicable with the air intake passage 31, and the atomization core 33 being fixable within the atomization chamber 36. The atomizer 30 may be provided with a lower liquid channel, which may communicate the liquid reservoir 32 with the atomizing chamber 36, and the aerosol-generating substrate in the liquid reservoir 32 may be guided to the atomizing core 33 via the lower liquid channel, so that the atomizing core 33 heats and atomizes the aerosol-generating substrate.

In some of these embodiments, the airflow sensor 40 is disposed along the first direction D1 with the atomizing base 34, and the airflow sensor 40 is located at the outer periphery of the intake passage 31. The first direction D1 may be a height direction of the atomizing device 100, and the first direction D1 may be a longitudinal direction or other directions of the atomizing device 100.

In some embodiments, the atomizing base 34 may be a single structure or may be a combination of multiple structures. For example, the atomizing base 34 may include an atomizing base 342 and an atomizing base 343, the atomizing base 342 and the atomizing base 343 may be arranged along the first direction D1, and the atomizing core 33 may be disposed between the atomizing base 343 and the atomizing base 342. The atomizing top base 342 may have the above-mentioned liquid-discharging passage.

In some of these embodiments, the atomizing top seat 342 and the atomizing base 343 can be coupled by a snap-fit connection. For example, the atomizing top base 342 may be provided with a protrusion, the atomizing base 343 may be provided with a clamping groove, and the protrusion of the atomizing top base 342 may be clamped in the clamping groove of the atomizing base 343. For another example, the atomizing top base 342 may be provided with a clamping groove, the atomizing base 343 may be provided with a protrusion, and the protrusion of the atomizing base 343 may be clamped in the clamping groove of the atomizing top base 342.

In some embodiments, the atomizing base 34 is provided with an air inlet tube 341, and a part of the air inlet channel 31 is surrounded by the air inlet tube 341, that is, a pipe in the air inlet tube 341 can be used as a part of the air inlet channel 31, and the air inlet tube 341 is communicated with the air inlet hole 11, so that external air can enter the air inlet tube 341 through the air inlet hole 11. The air inlet tube 341 may be configured as an atomizing base 343.

In some of these embodiments, the battery 20 is arranged along a second direction D2 with the atomizer 30, and the second direction D2 is distinct from the first direction D1. In this way, the aerosol-generating substrate leaked from the air inlet passage 31 is made not to easily enter the air flow sensor 40 arranged parallel to and at a distance from the outflow direction thereof, and also not to easily enter the battery 20 arranged in a direction different from the outflow direction thereof with respect to the atomizer 30. In addition, the leakage or the condensate generated in the atomizer 30 is not likely to flow into the battery 20 or the airflow sensor 40 in the first direction D1.

In some of these embodiments, the second direction D2 may be perpendicular to the first direction D1, e.g., the second direction D2 may be the width or thickness direction of the aerosolization device 100, such that the battery 20 and the atomizer 30 may be disposed side-by-side to the housing 10, helping to delay the flow of aerosol-generating substrate or condensate within the housing, helping to increase the flow path resistance of the aerosol-generating substrate or condensate, and reducing the flow of aerosol-generating substrate or condensate to the battery 20.

In some of these embodiments, referring to fig. 3 and 4, the atomizing base 34 may include a bracket receptacle 344, the bracket receptacle 344 being located on a side of the atomizing base 34 facing away from the atomizing core 33, e.g., the bracket receptacle 344 may be located on a side of the atomizing base 343 facing away from the atomizing core 33. The bracket receiving part 344 may be provided with a receiving groove 3441, and the receiving groove 3441 may receive the air flow sensor 40. The holder receiving portion 344 may be configured as an atomizing base 343.

In some embodiments, the atomizing base 34 further has an actuation air passage 37, and the actuation air passage 37 may communicate the air inlet tube 341 with the accommodating groove 3441, so that the air flow sensor 40 can detect the air pressure change or the flow rate change of the air flow in the air inlet channel 31 through the actuation air passage 37. For example, one side of the air flow sensor 40 communicates with the air intake passage 31 through the start-up air passage 37, and the other side of the air flow sensor 40 communicates with the outside atmosphere through the air intake hole 11; when the user inhales, the air pressure on the side of the air flow sensor 40 that communicates with the start air passage 37 becomes smaller than the air pressure on the side of the air flow sensor 40 that communicates with the outside atmosphere, so that the air flow sensor 40 can detect the user's sucking action.

In some of these embodiments, the direction of extension of the actuation airway 37 is different from the direction of extension of the inlet channel 31, thereby helping to delay the flow of aerosol-generating substrate or condensate from the inlet channel 31 to the actuation airway 37, helping to increase the flow resistance of the aerosol-generating substrate or condensate, and reducing the flow of aerosol-generating substrate or condensate to the airflow sensor 40, which would otherwise cause the airflow sensor 40 to self-actuate.

In some embodiments, the extending direction of the start air passage 37 and the extending direction of the air intake passage 31 may be disposed at an angle, for example, the extending direction of the start air passage 37 and the extending direction of the air intake passage 31 may be perpendicular to each other.

In some of these embodiments, the extending direction of the intake passage 31 may be the first direction D1, and the extending direction of the activation air passage 37 may be the second direction D2.

In some of these embodiments, the bracket receiving portion 344 and the air intake tube 341 are arranged along the second direction D2, such that the arrangement of the bracket receiving portion 344 and the air intake tube 341 is adapted to the arrangement in which the air intake passage 31 and the start air passage 37 are perpendicular to each other.

In some of these embodiments, the connection bracket 70 may include a sensor collar 71, the sensor collar 71 may be sleeved outside the airflow sensor 40, and both the sensor collar 71 and the airflow sensor 40 are located within the receiving slot 3441. In this way, the sensor collar 71 contributes to improving the air tightness of the opposite sides of the air flow sensor 40 in the holder accommodating portion 344, and to improving the sensitivity of detection of the air flow sensor 40.

In some embodiments, the connection bracket 70 may further include a tube collar 72, where the tube collar 72 is connected to the sensor collar 71, and the tube collar 72 is sleeved outside the air inlet tube 341, so as to help improve the stability of connection between the connection bracket 70 and the atomizing base 34, so that the connection bracket 70 is not easy to separate from the atomizing base 34.

In some of these embodiments, the atomizing device 100 may further include a control board 50, and the air flow sensor 40 may be fixed to the control board 50, for example, the air flow sensor 40 may be fixed to a plate body of the control board 50.

In this manner, the aerosolization device 100 is facilitated to charge the battery 20 via the charging interface 51.

In some of these embodiments, the aerosolization device 100 can also be provided with a wireless charging module positioned within the housing 10 to facilitate wireless charging of the aerosolization device 100.

In some of these embodiments, the charging interface 51 and the airflow sensor 40 may be arranged along the second direction D2, and the charging interface 51 and the battery 20 may be arranged along the first direction D1. In this way, the charging interface 51 is facilitated to be located away from the air inlet channel 31, reducing the flow of aerosol-generating substrate or condensate to the charging interface 51.

In some of these embodiments, the housing 10 may be formed by a combination of multiple structures. Referring to fig. 3 and 5, for example, the atomizing device 100 may further include a first housing 12 and a second housing 13 connected, the atomizer 30 and the battery 20 may be mounted to the first housing 12, and the control board 50 and the air flow sensor 40 may be mounted to the second housing 13.

In some of these embodiments, the connection between the first housing 12 and the second housing 13 may be achieved by a snap-fit structure. For example, the first housing 12 may be provided with a protrusion, the second housing 13 may be provided with a clamping groove, and the protrusion of the first housing 12 may be clamped in the clamping groove of the second housing 13.
