Abstract

The present disclosure illustrates a sensor-controlled nasal aspirator including a distance sensing unit, a micro processing unit and an air pump. The distance sensing unit is configured to sense a distance between a target object and the distance sensing unit. The micro processing unit is configured to store a preset distance, and receive and process the distance transmitted from the distance sensing unit, and transmit an action command signal when the distance is not higher than the preset distance. The air pump is configured to receive the action command signal and performs a target action according to the action command signal.

Claims

1. A sensor-controlled nasal aspirator, comprising:

a suction head arranged for aligning with a target object

a distance sensing unit for continuously sensing a distance between the target object and the distance sensing unit;

a micro processing unit operatively linked to the distance sensing unit to store a preset distance, receive and process the distance transmitted from the distance sensing unit, wherein the micro processing unit transmits an action command signal when the distance is not larger than the preset distance; and

an air pump operatively linked to the micro processing unit, wherein the air pump is activated for extracting air at the suction head to the target object when the air pump receives the action command signal from the micro processing unit.

2. The sensor-controlled nasal aspirator according to claim 1, further comprising a switch unit being actuated to control the micro processing unit in an on-and-off manner.

3. The sensor-controlled nasal aspirator according to claim 2, wherein the switch unit is a button switch.

4. The sensor-controlled nasal aspirator according to claim 1, wherein the distance sensing unit is an infra-red sensor or an ultrasound sensor.

5. The sensor-controlled nasal aspirator according to claim 1, further comprising a display unit operatively linked to the micro processing unit, wherein the display unit displays indicators for remained power and suction strength of the sensor-controlled nasal aspirator.

6. The sensor-controlled nasal aspirator according to claim 1, wherein the micro processing unit transmits a stop command signal to the air pump to deactivate the air pump when the distance is larger than the preset distance so as to stop extracting air at the suction head to the target object.

7. The sensor-controlled nasal aspirator according to claim 1, wherein the micro processing unit stores a preset distance range, and determines whether an absolute value of a difference between the distance and the preset distance is out of the preset distance range;

and

wherein according a determination result, the micro processing unit enables the distance sensing unit to resume sensing the distance or transmits the action command signal to the air pump to perform the target action.
