Referring to fig. 1-4, the present application provides an aerosol inhaler 100, wherein the aerosol inhaler 100 is used for aerosolizing a liquid for oral-nasal inhalation by a person. The liquid may be a liquid of a medicament.

The aerosol inhaler 100 includes a first housing 10, a second housing 20, a power source 30, a controller 40, a switch 50, an oscillating actuator 60, and an airflow sensing member 70. The first housing 10 forms a first airflow port 11 and a second airflow port 12, and the first airflow port 11 is communicated with the second airflow port 12 to form an airflow channel 13. The first airflow port 11 is used for an airflow channel 13 opposite to the mouth and nose. The second housing 20 is detachably connected to the first housing 10, and is configured to accommodate a liquid bottle 80, where the liquid bottle 80 is a bottle filled with the liquid. The power source 30 is electrically connected to the controller 40 for providing power to the controller 40. The switch 50 is disposed on the first housing 10, and is used for controlling the controller 40 to operate according to an operation on the switch 50. The oscillation actuator 60 is connected to the liquid bottle 80. The airflow sensing member 70 is used for sensing whether the airflow direction in the airflow channel 13 is towards the first airflow port 11 and transmitting the sensing result of the airflow direction to the controller 40. The controller 40 sends an actuating signal to the oscillating actuator 60 when the airflow direction is toward the first airflow port 11, and sends a stop signal to the oscillating actuator 60 when the airflow direction is not toward the first airflow port 11. The oscillating actuator 60 is configured to initiate oscillation in response to the actuation signal to generate a spray from the liquid in the liquid bottle 80 toward the airflow channel 13, such that the spray flows into the nose through the first airflow port 11 in the airflow direction. The oscillation actuator 60 is also used to stop oscillating the liquid in the liquid bottle 80 according to the stop signal. When the airflow direction faces to the first airflow port 11, the airflow direction is the direction of inhaling air when the mouth and the nose are opposite to the first airflow port 11, so that the liquid in the liquid bottle 80 generates spray for people to inhale; when the air flow direction is not toward the first air flow port 11, the mouth and nose are opposite to the direction of the exhaled air when the first air flow is opposite to the mouth and nose, or no mouth and nose are opposite to the direction of the exhaled air when the first air flow is opposite to the mouth and nose, the liquid in the liquid bottle 80 stops oscillating at the moment, so that excessive spray is prevented from being deposited into the mouth and nose during exhalation, or waste caused by generation of redundant spray is avoided.

In one embodiment, the first housing 10 includes a duct 14, and a first receiving body 15 and a second receiving body 16 connected to the outside of the duct 14. The air flow channel 13 is formed on the duct 14. The first air flow port 11 is formed at one end of the duct 14, the second air flow port 12 is located at the other end of the duct 14, and the second air flow port 12 includes a plurality of perforations 121 located at one end of the duct 14. The first receiving body 15 forms a first receiving groove 151 for receiving the airflow sensing member 70. The second receiving body 16 is located at one end of the duct 14 of the second air flow port 12. The second receiving body 16 forms a second receiving groove 161 and an opening 162 communicating with the second receiving groove 161. The second receiving groove 161 is used for receiving the power supply 30 and the controller 40, and the opening 162 is used for receiving the switch 50.

In one embodiment, the airflow sensing member 70 includes a first sensing member 71 and a second sensing member 72. The first sensing element 71 and the second sensing element 72 are disposed in the first receiving groove 151 side by side along the airflow channel 13, and the first sensing element 71 is located between the first airflow port 11 and the second sensing element 72. The first sensing member 71 transmits a first signal transmittable to the airflow channel 13, the second sensing member 72 transmits a second signal transmittable to the airflow channel 13 and receives the first signal, the first sensing member 71 is further configured to receive the second signal, and the airflow direction is determined to be directed toward the first airflow port 11 when a time interval T1 during which the second signal is received by the first sensing member 71 is shorter than a time interval T2 during which the first signal is received by the second sensing member 72. In one embodiment, the duct 14 forms a through hole (not shown) communicating with the first receiving groove 151 and opposite to the first sensing member 71 and the second sensing member 72, and the first signal and the second signal are transmitted to the airflow channel 13 through the through hole.

In one embodiment, the first sensor 71 and the second sensor 72 are ultrasonic sensors. The ultrasonic signal emitted from the first sensor 71, i.e. the first signal, is transmitted to the airflow channel 13 and then reflected by the opposite inner wall of the duct 14, so that the second sensor 72 senses the first signal, and similarly, the ultrasonic signal emitted from the second sensor 72, i.e. the second signal, is transmitted to the airflow channel 13 and then reflected by the opposite inner wall of the duct 14, so that the first sensor 71 senses the second signal, when the airflow direction is toward the first airflow port 11, the time interval T1 of the ultrasonic signal sensed by the first sensor 71 close to the first airflow port 11 is shorter than the time interval T2 of the ultrasonic signal sensed by the second sensor 72 far from the first airflow port 11. Thus, when the time interval T1 of the ultrasonic signal sensed by the first sensor 71 is longer than the time interval T2 hours of the ultrasonic signal sensed by the second sensor 72 of the first airflow port 11, it is determined that the airflow direction is toward the first airflow port 11.

In one embodiment, referring to fig. 5, the aerosol inhaler 100 further comprises a computing element 91 and a display screen 92. The airflow sensing member 70 also serves to sense the airflow velocity within the airflow passage 13. The calculation unit 91 is configured to calculate the amount of airflow passing through the airflow channel 13 based on the time of the airflow toward the second airflow port 12, the airflow velocity at the corresponding time, and the cross-sectional area of the airflow channel 13 when the user blows air toward the aerosol inhaler 100, thereby obtaining the vital capacity data. The display screen 92 can be used to display the vital capacity data, so that the user and the related personnel of the aerosol inhaler 100 can check the vital capacity data of the user to determine whether the medicament has a therapeutic effect. The aerosol inhaler 100 further comprises a communication interface 93, such as bluetooth, wherein the communication interface 93 is used for being in communication connection with an electronic device 200, such as a mobile phone, and transmitting the vital capacity data of the user to the electronic device 200.

The aerosol inhaler 100 generates the aerosol for inhalation when the airflow direction is toward the first airflow direction, such as when the air is inhaled through the mouth and nose, and stops oscillating the liquid in the liquid bottle 80 when the airflow direction is not toward the first airflow port 11, so as to ensure the amount of the aerosol inhaled through the mouth and nose and reduce the deposition of the aerosol into the mouth and nose during exhalation.

It will be appreciated by those skilled in the art that the above embodiments are illustrative only and not intended to be limiting, and that suitable modifications and variations to the above embodiments are within the scope of the disclosure provided that the invention is not limited thereto.
