Description

Technical Field

[0001] This utility model relates to the technical field of universal exhaust hoods, and in particular to an exhaust outlet for a universal exhaust hood. Background Technology

[0002] Universal exhaust hoods are mainly used to quickly discharge small particulate matter or gases such as dust, hot air, volatile gases, and harmful gases generated during experiments or production processes. Existing universal exhaust hoods, such as the universal exhaust hood for welding position ventilation disclosed in utility model patent CN215785560U and the universal exhaust hood equipped with an adsorption device disclosed in utility model patent CN205146858U, can all achieve universal exhaust.

[0003] However, during use, it was found that the existing universal exhaust hood has a relatively simple air outlet structure, which is not convenient to adapt to exhaust pipes of different diameters, affecting the installation effect and sealing effect, resulting in poor practicality. Therefore, there is an urgent need for a universal exhaust hood air outlet to improve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a universal exhaust hood outlet that has a fixed structure installed on the universal exhaust hood and a connecting structure installed on the exhaust pipe, so that the gas discharged from the universal exhaust hood passes through the fixed structure and the connecting structure and enters the exhaust pipe, thereby improving the practicality of the universal exhaust hood outlet.

[0005] This utility model provides a universal exhaust hood outlet, which includes a fixed structure and a connecting structure, the connecting structure being installed on the fixed structure.

[0006] The fixed structure, in conjunction with the connecting structure, connects the universal exhaust hood to the exhaust pipe.

[0007] The fixed structure is installed on the universal exhaust hood, and the connecting structure is installed on the exhaust pipe, so that the gas discharged from the universal exhaust hood passes through the fixed structure and the connecting structure and enters the exhaust pipe, thereby improving the practicality of the universal exhaust hood's air outlet.

[0008] Preferably, the fixing structure includes an air outlet fixing base, screws, and a sealing ring. The air outlet fixing base is installed on the exhaust port of the universal exhaust hood by screws, and the sealing ring is located between the air outlet fixing base and the universal exhaust hood. The sealing ring seals the gap between the air outlet fixing base and the universal exhaust hood, and the air outlet fixing base supports and fixes the connecting structure, thereby improving the practicality of the air outlet of the universal exhaust hood.

[0009] Preferably, the right end of the air outlet fixing base is provided with an annular positioning groove; the sealing ring is limited by the annular positioning groove, thereby improving the stability of the sealing ring.

[0010] Preferably, the connection structure includes a pipe connector and a clamp. One end of the pipe connector is installed on the air outlet fixing base, and the clamp is fitted onto the pipe connector. The other end of the pipe connector is fitted onto the exhaust pipe, and the clamp is locked so that the inner wall of the pipe connector is tightly fitted with the outer wall of the exhaust pipe, thereby improving the practicality of the universal exhaust hood air outlet.

[0011] Preferably, the pipe connector is made of soft rubber; this makes it easy to fit the other end of the pipe connector onto exhaust pipes of different diameters, and also makes it easy to tighten the clamp so that the inner wall of the pipe connector fits tightly against the outer wall of the exhaust pipe, thereby improving the practicality of the exhaust hood outlet.

[0012] Preferably, the outer surface of the pipe joint is provided with an annular limiting groove; the annular limiting groove facilitates the limiting of the clamp, thereby improving the locking effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the fixed structure is installed on the universal exhaust hood, and the connecting structure is installed on the exhaust pipe, so that the gas discharged from the universal exhaust hood passes through the fixed structure and the connecting structure and enters the exhaust pipe, thereby improving the practicality of the exhaust hood outlet.
