[0034] It also includes a wind negative pressure system, which includes a wind collecting structure 2; the wind collecting structure 2 is set to a trumpet-type wind collecting structure 2 with a large opening area at one end and a small opening area at the other end. The end of the wind collecting structure 2 with a large opening area serves as an air inlet, and the other end with a small opening area serves as an air outlet; the wind collecting structure 2 is provided with an opening on the lower side surface at one end of the air outlet as an air intake; the wind collecting structure 2 is provided with a horizontal surface on the lower side surface at one end of the air outlet at the air intake; the air intake is a horizontally arranged opening; the air outlet is connected to the air intake; a one-way valve 5 with a conducting direction toward the air intake is provided between the air outlet and the air intake; the wind negative pressure system also includes a wind-converting system, and the action execution mechanism 3 of the wind-converting system drives the wind collecting structure 2 to be connected; first, by setting the wind collecting structure 2, the trumpet-type structure will collect more wind, and in the channel When the size is reduced, the wind flow rate will increase, and the flowing wind will form negative pressure. The air intake of the wind collecting structure 2 is set horizontally, and the air intake of the wind collecting structure 2 on the lower side of the air outlet will inhale air to the air outlet of the ventilation duct 1 due to the negative pressure, and discharge the air, bacteria and viruses in the hospital, without consuming electricity to drive, saving electricity. Secondly, a one-way valve 5 with the conduction direction facing the air intake is set between the air outlet and the air intake to prevent wind from flowing back into the ventilation duct 1 and affecting the ventilation effect of the ventilation duct 1. Finally, through the wind system, the wind collecting structure 2 can be automatically adjusted, and the air inlet is facing the opposite wind, thereby improving the wind collecting effect of the wind collecting structure 2 and thus improving the air intake effect at the air intake of the wind collecting structure 2. The wind system is a system commonly used in wind turbines 33 to ensure that the wind turbines 33 can continuously adjust their direction to adapt to changing wind directions.

[0035] The air outlet and the air intake are connected via a rotating structure, so that the air collecting structure 2 can rotate on the ventilation duct 1, making it convenient for the air collecting structure 2 to adjust its direction toward the incoming wind.

[0036] The lower side of the wind collecting structure 2 is at the air intake, and is a structure with a gradually increasing height from the air inlet to the air intake; the gradually increasing height from the air inlet to the air intake gradually increases the wind speed entering the wind collecting structure 2, thereby improving the air intake effect of the air intake.

[0037] Two wind collecting structures 2 are provided, and the two wind collecting structures 2 are assembled in reverse, and the air outlets of the two wind collecting structures 2 are connected; by providing two wind collecting structures 2, the wind negative pressure system can accept positive and reverse winds, thereby improving the wind collection effect of the wind collecting structure 2, reducing the adjustment angle required for the wind system, and making the wind collecting device operate more stably.

[0038] The area of the air inlet is greater than 3 times the area of the air outlet; the area of the air outlet is greater than 1 times the area of the air outlet and less than 1.5 times the area of the air outlet; ensuring that the wind collecting structure 2 can collect enough wind.

[0040] When in use, the wind system of the wind negative pressure system adjusts the direction of the air inlet of the wind collecting device through the action actuator 3, so that the air inlet can be adjusted to the direction of the opposite wind in real time. The wind is accelerated through the trumpet structure of the wind collecting device and blown out from the other end of the wind collecting structure 2 through the air intake. The accelerated wind forms a negative pressure, so that the air intake has suction. The air intake sucks out the air through the air outlet of the ventilation duct 1, exhausts the fresh air system of the hospital, and discharges the air, bacteria and viruses in the hospital. Since there is no need to use a fan, energy is saved.

[0046] When in use, the wind vane 4 is blown to rotate, and the rotation signal is sent to the wind control terminal through the angle sensor. The wind control terminal controls the operation of the motor 33 according to the model of the angle sensor received. The motor 33 drives the gear 32 to rotate, and the gear 32 drives the ring gear 31 to rotate.
