Claims

1. A powered emergency suction unit comprising a main unit and a face mask, characterised in that: The main unit includes a housing and a bottom cover, as well as a vacuum pump, a solenoid valve, and a control main board installed inside the housing. The housing is a hollow structure, and the housing and the bottom cover are sealed together. The housing and the bottom cover cooperate to form a vacuum chamber. The vacuum pump is installed above the vacuum chamber, and the air intake of the vacuum pump is connected to the vacuum chamber. The vacuum pump is electrically connected to the control main board. The bottom cover has a through-hole with an air port connected to the vacuum chamber. The solenoid valve is installed above the air port. The solenoid valve is electrically connected to the control main board and can open and close the air port under the control of the control main board. The air port is connected to the face mask.

2. An electrically powered suction unit as claimed in claim 1, characterised in that The control motherboard is mounted above the vacuum pump via a first fixed bracket, and the first fixed bracket is fixedly connected to the housing.

3. An electrically powered suction unit as claimed in claim 1, characterised in that The host also includes a power supply, which is installed outside the vacuum chamber and is electrically connected to the control motherboard, vacuum pump and solenoid valve.

4. An electrically powered suction unit according to claim 1, wherein The host also includes a pressure sensor, which is installed above the vacuum chamber and electrically connected to the control motherboard. The pressure sensing port of the pressure sensor is connected to the vacuum chamber.

5. An electric emergency suction device as described in claim 4, characterized in that, The vacuum pump's suction port and the pressure sensor's pressure sensing hole are both provided with a first seal at the connection point with the vacuum chamber, and the outer shell and the bottom cover are provided with a second seal.

6. An electrically powered suction unit according to claim 1, characterised in that The main unit also includes a top cover, which is mounted on top of the control motherboard and is fastened to the outer casing; a button is provided on the upper surface of the top cover, which is electrically connected to the control motherboard and is used to adjust the negative pressure intensity of the vacuum pump.

7. An electrically powered suction unit according to claim 1, wherein The mask includes a tongue depressor tube, the upper end of which passes through the top of the mask and is connected to the vacuum chamber via the air vent.

8. An electrically powered suction unit according to claim 1, characterised in that The solenoid valve is mounted above the air port via a second fixed bracket, which is fixedly connected to the outer casing. The solenoid valve includes a return spring and a silicone plug adapted to the air port. The return spring is used to push the silicone plug to seal the air port when the power is off. The solenoid valve has a pulling force greater than 10N, and the return force of the return spring is greater than 8N. The pulling force of the solenoid valve is always greater than the return force of the return spring.

9. An electrically powered suction unit according to claim 1, characterised in that A hanging bracket is provided on the outside of the outer casing.

10. An electrically powered suction unit according to any one of claims 1 to 9, wherein, The negative pressure intensity of the vacuum pump is between 0 and -100 kPa, and the maximum negative pressure intensity of the vacuum pump is between -60 kPa and -100 kPa; the volume of the vacuum chamber is 100-1000 cm 3 .
