Embodiment Construction

[0038] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0039] see figure 1 ,figure 2, image 3 and Figure 4 Shown is an air curtain generating device provided by the first embodiment of the present invention. The air curtain generating device includes a blower 10 and an air guide pipe 20 . The air curtain generating device of the present invention is used to generate an air curtain 70, surround the pollution source generated by a workbench 50, and assist an exhaust machine 60 to discharge the pollution source. The number of blowers 10 is not limited, and can be used according to the actual situation of the workbench 50. Increase in area or volume.

[0040] The blower 10 is used to generate an airflow, and the blower 10 has an air outlet 11 for the airflow to blow out. The air outlet 11 communicates with an air duct 2...

Abstract

The invention discloses an air curtain generator, which comprises a blower and an air duct. The blower generates air flow, and the air duct receives the air flow generated by the blower. The air duct comprises a closed section for the air flow running through and an air outlet section. The air outlet section receives the air flow running through the closed section and is provided with a plurality of air outlets for the air flow running through, and the air outlets are arranged orderly according to the flowing paths of the air flow. The air outlet section is divided into a transition region corresponding to the closed section and a forward flow region with a closed end, wherein, the total air outlet sectional area of the unit length of the forward flow region is gradually increased from the closed end towards the transition region, and the total air outlet sectional area of the unit length of the transition region is less than or equal to the minimum value of that of the forward flow region, therefore, the air flow from the air outlet forms an air curtain with even flow rate.

Description

technical field [0001] The invention relates to an air curtain generating device, in particular to an air curtain generating device which facilitates the average flow of air flow. Background technique [0002] In many workplaces that produce harmful pollution sources, such as oil fumes, volatile organic solvents, lead, dust or specific chemical substances, local exhaust devices are generally installed above the workbench according to actual needs, and the pollution sources are discharged in a centralized manner. to maintain human health. The most common local exhaust device is the exhaust machine installed above the workbench, but the collection efficiency of this type of exhaust machine will be affected by the lateral diffusion of pollution sources or the installation height of the workbench and the exhaust machine. Cause its exhaust effect is not good. In order to solve the above problems, a kind of exhaust cabinet with back wall, side wall and front sliding door appears...
