[0002] The production of printed circuit boards (PCBs) generates a significant amount of waste gas. This waste gas originates primarily from various stages of the production process, including solvent usage, process steps, and the materials themselves. When heat is required during processing, thermal waste gas is generated. Because this waste gas contains many harmful substances, it cannot be discharged directly into the air and must be collected and treated in a centralized manner.

[0003] In the prior art, there is an adaptive exhaust gas collection hood device with a publication number of CN215508276U, which includes: a workbench, a plastic mounting frame, an adaptive gas collection hood body, an adaptive pressure difference adjustment frame structure, a connecting hose, a detachable dust curtain structure, a rope connecting frame structure, a high-elasticity spring pull rope, a lifting frame, a connecting rod and a triangular slot. The plastic mounting frame is arranged on the upper part of the workbench, the adaptive gas collection hood body is integratedly arranged on the upper part of the plastic mounting frame, the adaptive pressure difference adjustment frame structure is installed in the upper middle position of the adaptive gas collection hood body, and the left side of the connecting hose is connected to the adaptive pressure difference adjustment frame structure; by setting an outlet pipe and an electric air volume regulating valve, the electric air volume regulating valve can adjust the size of the collected air volume, which is convenient for the staff to automatically adjust the collection position according to the demand for air volume.

[0004] However, in the above scheme, when the collected exhaust gas contains water vapor, the water vapor will gather at the bottom of the adaptive gas collection hood body. When the gathered water vapor condenses into water droplets, the water droplets will fall onto the workbench below the adaptive gas collection hood body, thereby affecting the work on the workbench. Utility Model Content

[0005] The purpose of the utility model is to provide a hanging type hot exhaust gas collecting device, which can prevent water droplets formed on the bottom of the gas collecting hood from dripping downwards.

[0006] To achieve the above-mentioned purpose, a suspended hot exhaust gas collection device is provided, which includes: a frame; an air collecting hood, which is connected to the frame, a connecting tube is provided in the air collecting hood, a plurality of air holes are opened on the circumference of the connecting tube, an inverted funnel-shaped water collecting plate is provided at the bottom of the connecting tube, an annular water collecting trough is provided at the bottom of the air collecting hood, the edge of the water collecting plate is located above the water collecting trough, an outlet pipe is connected to the outside of the air collecting hood, and the outlet pipe is connected to the water collecting trough; a collecting component, which includes a collecting pipe, an exhaust fan and a collecting tank, one end of the collecting pipe is connected to the connecting tube, the collecting pipe is provided with an exhaust fan in series, the exhaust fan is connected to the frame, and the other end of the collecting pipe is connected to the collecting tank; a cooling component, which is connected to the air collecting hood.

[0008] By setting up a water collecting plate and a water collecting trough, when the exhaust gas contains water vapor, the water vapor gathers at the bottom of the water collecting plate, and the gathered water vapor condenses into water droplets. The water droplets drip along the water collecting plate into the water collecting trough, and the water in the water collecting trough is discharged through the outlet pipe, thereby preventing the water droplets formed at the bottom of the gas collecting hood from dripping downwards, and preventing the water droplets from affecting the work below the device.

During this process, the slider moves up and down along the mounting tube, and the first damping spring above the slider is compressed or stretched, and the first damping spring below the slider is stretched or compressed. When the first damping spring is compressed or stretched, it can absorb energy, thereby reducing the vibration of the hood and preventing the vibration of the hood from being transmitted to the fixed plate through the support rod.
