[0026] The utility model is an improvement on the traditional umbrella, and is mainly composed of an umbrella cloth 1, an umbrella pole 2, an umbrella handle 3 and a one-way ventilation device. One end of the umbrella pole 2 is fixedly connected to the umbrella handle 3. The umbrella handle 3 is a hook-shaped type and can be hung on some tables or poles for easy placement. The umbrella pole 2 is fixedly connected to the umbrella cloth 1 near the other end, and the umbrella head 4 is fixedly connected to the head of the other end of the umbrella pole 2. The center of the umbrella cloth 1 is fixedly connected to the one-way ventilation device. When the umbrella is held up, when the wind blows toward the umbrella from the position below the umbrella cloth 1, the one-way ventilation device is opened by the airflow to form an opening, so that part of the airflow flows out from the opening. When the airflow slows down or when the umbrella is erected, the one-way ventilation device will close to form a complete umbrella cloth 1, so that rainwater cannot flow into it. The one-way ventilation device is mainly composed of an umbrella top 11 and a rotating piece 12. One end of the rotating piece 12 is rotatably connected to the umbrella top 11. The angle of rotation is 0° to 30°. The opening formed by this angle can allow the airflow to have enough space to pass through the umbrella cloth 1.

When it is designed as 4 rotating pieces 12, when the rotating piece is rotated to the maximum angle, the rotating piece and the umbrella top are in contact. The through hole area is large, which improves the efficiency and saves materials. As a normal rainproof tool, after the umbrella is opened, if there is a strong wind blowing the umbrella tilted, the rotating piece 12 is blown open by the airflow to form a ventilation channel, so that part of the airflow passes through it, reducing the impact of the airflow on the umbrella cloth 1. When the airflow is smooth, the umbrella can be picked up vertically normally. The rotating piece 12 falls and abuts against the umbrella top 11 through gravity and the magnetic force between the magnetic piece 1 111 and the magnetic piece 2 121, forming a sealed umbrella cloth 1, thereby completing the rainproof effect.
