Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] A ventilating fan that can be quickly disassembled and assembled comprises a housing 1, an air inlet grille 2, an air outlet grille 3, a motor and a fan wheel 16;

[0027] The upper and lower ends of the housing 1 are connected to form an air inlet at the lower end of the housing 1 and an air outlet at the upper end of the housing 1. The motor is vertically installed in the housing 1, and the motor is not in contact with the inner wall of the housing 1 around it. A channel for airflow is formed between the motor and the inner wall of the housing 1. A wind wheel 16 is installed at the output end of the motor. The air inlet grille 2 and the air outlet grille 3 are respectively installed at the lower end and the upper end of the housing 1.

[0028] The motor drives the wind wheel 16 to rotate, thereby driving the air at the air inlet to flow to the air outlet for discharge.

[0029] The shell 1 is provided with a quick disassembly structure, which includes a torsion spring. The lower end of the shell 1 extends in all directions to form a mounting edge 4. At least two torsion springs are evenly arranged around the outer wall of the shell 1, preferably two torsion springs, which are symmetrically arranged on both sides of the shell 1. The torsion spring includes a spring body 5, and a first torsion bar and a second torsion bar 6 are connected to the spring body 5. A vertical socket 7 is provided on the outer wall of the shell 1, and the socket 7 matches the first torsion bar.

The first torsion bar is fixed on the housing 1, and the second torsion bar 6 extends downward in a natural state. When installing, hold both sides of the installation edge 4 with both hands, extend your fingers, push the corresponding second torsion bar 6 and rotate it upward, so that the second torsion bar 6 is close to the side wall of the housing 1, and then insert the upper end of the housing 1 and the torsion spring into the installation hole of the ceiling. After the upper end of the second torsion bar 6 is inserted into the installation hole, release your fingers, and the second torsion bar 6 will lose external force and return to its original position by elasticity, rotate downward, and press against the ceiling board. The inner side will drive the entire shell 1 to move upward until the mounting edge 4 is attached to the outer side of the ceiling board, so that the second torsion bar 6 and the mounting edge 4 are clamped by the elastic force of the second torsion bar 6 to fix the ceiling board at the edge of the mounting hole. When removing, it is only necessary to hold the mounting edge 4 at the lower end of the shell 1 and pull it down hard, squeeze the second torsion bar 6 and rotate it upward, so that the ventilation fan can be pulled out of the mounting hole. Through the utility model, the ventilation fan can be quickly installed and removed.
