Detailed Embodiments

[0021] The present utility model will be further described below with reference to the accompanying drawings.

[0022] A ventilation device for both normal and epidemic prevention use, comprising a box body 14, a wind blocking component 3, a filter sheet 12 and an exhaust fan 13. An air inlet 10 and an air outlet 11 are provided on the box body 14. The filter sheet 12 is arranged at the air inlet 10, and the exhaust fan 13 is arranged at the air outlet 11. A first air outlet 1 and a second air outlet 2 are provided in the middle of the box body 14. The first air outlet 1 is used for normal exhaust, that is, at this time the ward is a normal ward, and the second air outlet 2 is used for epidemic exhaust, that is, at this time the ward is converted into a negative pressure ward. The air at the air inlet 10 in the box body 14 can only flow to the air outlet 11 through the first air outlet 1 or the second air outlet 2. The wind blocking component 3 is slidably installed in the box body 14. By moving the wind blocking component 3, ventilation of the first air outlet 1 or the second air outlet 2 is achieved, so that the ventilation device is applicable to a normal ward or a negative pressure ward.

[0023] A constant air volume valve 4 is provided in the second air outlet 2. The constant air volume valve 4 is an electric valve to ensure that when the second air outlet 2 ventilates, the negative pressure requirement in the ward is met.

[0024] At least two mounting plates 5 are provided in the box body 14. The two mounting plates 5 partition the box body 14. The air inlet 10 and the air outlet 11 are located on both sides of the mounting plate 5. Two air duct pipes 6 are provided between adjacent mounting plates 5. The first air outlet 1 and the second air outlet 2 are formed in the ventilation device through the two air duct pipes 6.

[0025] Both ends of the air duct pipe 6 extend out of the mounting plate 5. A curled edge 7 is provided on one side of the air duct pipe 6. The wind blocking component 3 is arranged on the side of the curled edge 7 of the air duct pipe 6. One side of the air duct pipe 6 is closed by the wind blocking component 3 abutting against the curled edge 7. The curled edge 7 is arc-shaped to prevent the air duct pipe 6 from damaging the rubber pad 3-2 on the wind blocking plate 3-1 during the movement of the wind blocking component 3.

[0026] The wind blocking component 3 includes a wind blocking plate 3-1 and a driving member. Guide rails 8 are respectively installed at the upper and lower ends of the box body 14. The wind blocking plate 3-1 is slidably installed in the ventilation device through the guide rails 8. The driving member is connected to the wind blocking plate 3-1 to drive the wind blocking plate 3-1 to slide in the ventilation device.

[0027] Two travel switches 9 are provided in the guide rail 8. The travel switches 9 are adapted to the wind blocking plate 3-1 to limit the movement stroke of the wind blocking plate 3-1. When the wind blocking plate 3-1 abuts against one of the travel switches 9, the wind blocking plate 3-1 covers the first air outlet 1 and the second air outlet 2 ventilates. When the wind blocking plate 3-1 abuts against the other travel switch 9, the wind blocking plate 3-1 covers the second air outlet 2 and the first air outlet 1 ventilates, so that the ventilation device meets the ventilation requirements of both a conventional ward and a negative pressure ward.

[0028] One side of the wind deflector 3-1 is provided with a rubber pad 3-2, and the rubber pad 3-2 is adapted to the first air outlet 1 or the second air outlet 2. The rubber pad 3-2 has a certain elasticity. When the wind deflector 3-1 abuts against the first air outlet 1 or the second air outlet 2, the deformation of the rubber pad 3-2 is used to ensure the sealing performance of the connection between the wind deflector 3-1 and the first air outlet 1 or the second air outlet 2.

[0029] The driving member includes a driving motor 3-3, a lead screw 3-4 and a slider 3-5. The driving motor 3-3 is fixed inside the ventilation device. The lead screw 3-4 is connected to the driving motor 3-3. The slider 3-5 is installed on the lead screw 3-4 by threads, and the slider 3-5 is connected to the wind deflector 3-1.
