Problems solved by technology
In order to solve the above problems, the Chinese Patent Publication No. CN202545359U discloses a ventilator with a multifunctional air inlet interface, which is provided with a square flange and a circular air inlet pipe corresponding to the square connecting pipe and the circular connecting pipe respectively. However, the size of its square flange is fixed, and due to the existence of various models and errors in production, the square connecting pipe that needs to be installed often cannot match the fixed square flange, and accurate connection cannot be achieved , it is necessary to align the misaligned through holes when connecting, which requires re-cutting the through holes, which reduces the work efficiency, so it is necessary to improve

The invention provides a ventilator with a multifunctional air inlet connector. The ventilator comprises a shell and a motor driving an impeller in the shell to rotate. An air inlet is formed in the shell. The part, on the periphery of the air inlet, of the side wall of the shell is fixedly connected with an air inlet cylinder. An annular connecting flange is fixedly connected to the inner side wall of the outer end of the air inlet cylinder. Through holes are formed in the annular connecting flange. Four sliding rails are fixedly connected to the part, on the outer side of the air inlet cylinder, of the side wall of the shell and form a rectangular shape. A plurality of guiding grooves perpendicular to the longitudinal direction of each sliding rail are formed in the sliding rail. Each sliding rail is movably provided with a connecting plate parallel to the longitudinal direction of the sliding rail. Adjusting plates are connected to the connecting plates on one pair of opposite sliding rails in the four sliding rails. Adjusting through grooves are formed in each adjusting plate, and the corresponding connecting plates are provided with fastening grooves corresponding to the adjusting through grooves. The ventilator can adapt to square connecting pipes with different sizes, and the connecting efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of fan equipment, in particular to a fan with a multifunctional air inlet interface. Background technique [0002] The connecting pipes of the air inlet pipes of the existing ventilators are all round connecting pipes or square connecting pipes, which need one-to-one correspondence. It is very troublesome to match or connect the circular connecting pipe to a square connecting pipe to be connected with the air inlet pipe of the ventilator. In order to solve the above problems, the Chinese Patent Publication No. CN202545359U discloses a ventilator with a multifunctional air inlet interface, which is provided with a square flange and a circular air inlet pipe corresponding to the square connecting pipe and the circular connecting pipe respectively. However, the size of its square flange is fixed, and due to the existence of various models and errors in production, the square connecting pipe that needs to be in...
