Description

Technical Field

[0001] The present application relates to the field of smoke exhaust fans, and more particularly, to a fire smoke exhaust fan. Background Art

[0002] The main function of a smoke exhaust fan is to discharge the internal smoke. This technology is already very mature and is mainly used in the fields of fire smoke exhaust, production waste gas discharge, and ventilation. However, under normal circumstances, if the indoor air is normal, continuously operating the smoke exhaust fan for a long time will also affect the surrounding environment, and continuously using the smoke exhaust fan under fatigue conditions will also affect its service life.

[0003] The structure of the product can refer to a fire smoke exhaust fan disclosed in Chinese Patent Document No. 202320885895.6, which includes a wind barrel, a fan, a mounting seat, a smoke sensor switch, a smoke detector, a monitor, and a reminder. The fan is arranged inside the wind barrel, the mounting seat is arranged on the wind barrel, the smoke sensor switch is arranged on the mounting seat and electrically connected to the fan, the smoke detector is arranged on the mounting seat, the monitor is arranged on the wind barrel, and the reminder is arranged on the wind barrel. The reminder includes a fixed box, a working device, and a reminder ball. The fixed box is arranged on the wind barrel, the working device is arranged on the fixed box, and the reminder ball is arranged on the working device and slidably penetrates through the fixed box. The present utility model relates to the field of smoke exhaust fan design, and more particularly, to a fire smoke exhaust fan.

[0004] Both ends of the smoke exhaust pipe are provided with protective covers. However, in this patent, the two protective covers are separately arranged, and when disassembling, they also need to be disassembled separately, which is rather inconvenient.

[0005] Now, a fire smoke exhaust fan with convenient disassembly is provided. Summary of the Utility Model

A second installation strip is fixedly connected to the exhaust pipe. The fixing rod is slidably installed on the second installation strip, and the fixing rod is slidably installed with the second installation strip. The fixing rod passes through the second installation strip. A fixing groove corresponding to the fixing rod is provided on the first installation strip. A fixing spring is fixedly connected between the second installation strip and the first installation strip.

[0012] Further, the fixing spring is sleeved on the fixing rod.

[0013] Further, a pull ring is fixedly connected to the fixing rod.

[0014] Further, a limiting disc is fixedly connected to the output shaft of the exhaust fan motor. A fixing ring is fixedly connected to the exhaust fan, and the fixing ring corresponds to the limiting disc. A connecting piece is fixedly connected to the fixing ring. A third fixing bolt is threadedly connected to the connecting piece, and the third fixing bolt is threadedly connected to the output shaft of the exhaust fan motor.

[0015] Further, a baffle is provided in the exhaust pipe. The output shaft of the exhaust fan motor penetrates through the baffle, and the output shaft of the exhaust fan motor is rotatably connected to the baffle. A fixing strip is fixedly connected between the baffle and the exhaust pipe.

[0016] Furthermore, the fixing springs are provided in two numbers, and the two springs are symmetrically arranged between the first mounting strip and the second mounting strip.

[0017] Furthermore, a handle is fixedly connected to the connecting strip.

[0018] The beneficial effect of the present application lies in: providing a fire exhaust fan that is convenient to disassemble. BRIEF DESCRIPTION OF THE DRAWINGS
