Abstract

The invention discloses a wind collecting device for a window, which comprises a bracket, on which an air deflector with an arc surface structure is arranged, on which a connecting rod is connected, and a suction cup is arranged on the end of the connecting rod. The present invention adopts a wind deflector with an arc surface structure that can be fixed outside the window. After the wind deflector is fixed outside the window, the air deflector is used to guide the flow of air outside the window and change its flow direction so that more air can enter the room. , so as to increase the indoor air flow without using any energy consumption. The invention has the advantages of simple structure, no need to use electric power, low cost and good use effect.

Description

Window ventilation device

technical field

The invention relates to the mechanical field, in particular to a window wind collecting device.

Background technique

With the development of science and technology, people's living standards have been greatly improved. In terms of indoor ventilation, it is more common to use exhaust fans, and even people often choose to open windows to achieve indoor and outdoor ventilation. These methods have the defects of small ventilation and power consumption, and cannot solve the problem that there is wind outdoors but no ventilation indoors or there is wind outdoors and the indoor air intake is small. These problems bring many troubles for people's daily life.

Contents of the invention

The object of the present invention is: to provide a window wind collection device, which can increase the indoor ventilation rate under the condition of no power consumption, so as to overcome the deficiencies of the prior art.

The present invention is realized in the following way: the window wind collection device includes a bracket, an arc-shaped wind deflector is arranged on the bracket, a connecting rod is connected to the bracket, and a suction cup is arranged at the end of the connecting rod.

Both the bracket and the wind deflector are telescopic structures. Since the air deflector adopts a curved surface structure, it cannot be retracted forward and backward, so the bracket and the air deflector adopt a structure that can be stretched up and down. This structure can control the effective air guiding area of the air deflector and adjust it according to the needs of use.

Due to the adoption of the above-mentioned technical scheme, compared with the prior art, the present invention adopts a wind deflector with an arc surface structure that can be fixed outside the window. After the wind deflector is fixed outside the window, the air flow outside the window is guided by the wind deflector. Change its flow direction so that more air can enter the room, thereby increasing the indoor air flow without using any energy consumption. The invention has the advantages of simple structure, no need to use electric power, low cost and good use effect.

Accompanying drawing 1 is a structural representation of the present invention;

Accompanying drawing 2 is the side view of accompanying drawing 1;

Accompanying drawing 3 is the working schematic diagram of the present invention.

Detailed ways

Embodiments of the present invention: The structure of the window wind collecting device is as shown in Figure 1, comprises support 1, is provided with the wind deflector 2 of arc surface structure on support 1, is connected with connecting rod 3 on support 1, is connected with connecting rod 3 The end of the end is provided with a suction cup 4; the support 1 and the wind deflector 2 are telescopic structures, the support 1 and the wind deflector 2 are divided into upper and lower parts, wherein the lower half is a hollow sandwich structure, and its space can be just To accommodate the upper part, push the upper part into the lower part to achieve compression, and pull the upper part out of the lower part to restore it; the direction of expansion and contraction is shown by the arrow in Figure 2.

As shown in Figure 3, when in use, the suction cup 4 on the bracket 1 is fixed on the wall 5 (or the glass of the window) outside the window, and the air flow is changed by the wind deflector 2 after encountering the wind deflector 2 The direction allows more airflow to enter the room, thereby increasing the air circulation in the body.

Claims (2)
