Ventilating fan convenient to install

Abstract

The invention relates to a ventilating fan, in particular to a ventilating fan convenient to install. The ventilating fan comprises an outer frame, a casing, a rotating device and a motor box, whereinthe outer wall of the casing is provided with a sealing layer, and the casing is internally provided with a filter screen and the motor box. The filter screen and the casing are fixedly connected bya movable fixed seat. The motor box is internally provided with a motor and sound insulating cotton. The bottom of the motor box is provided with a smoke concentration sensor, and the base surface ofthe casing is provided with the outer frame. An oil tank is arranged at the bottom of the outer frame, the base surface of the oil tank is provided with a handle, and the outer frame is internally provided with the rotating device. The rotating device comprises a fan blade and a rotating head. The rotating head and the motor are connected by a rotating shaft in the rotating mode, and the rotatinghead is internally provided with a controller. One side of the outer frame is provided with a plug, the plug and the outer frame are linearly connected by a wire, and the top of a blocking piece is provided with a solar electronic board. The fan is simple in structure and convenient to install and achieves a certain promotion effect.

Description

technical field [0001] The invention relates to a ventilation fan, in particular to a ventilation fan which is easy to install. Background technique [0002] There are three types of ventilating fans: discharge type, suction type, and combination type. The discharge type enters the air from the natural air inlet and discharges the dirty air through the ventilation fan. The suction type sucks in fresh air through the ventilation fan and discharges the dirty air from the natural exhaust port. The combination type is that the suction and exhaust are completed by the ventilation fan, and the motor drives the fan blade to rotate and drive the airflow to exchange indoor and outdoor air. It is also called a ventilation fan. The purpose of ventilation is to remove indoor dirt. Air, adjust temperature, humidity and sensory effects, ventilation fans are widely used in homes and public places, but the functions of ventilation fans on the market are relatively single, and at the same ti...

Problems solved by technology

[0002] Ventilation fans have three types of ventilation: discharge, suction, and combined use. The discharge type enters the air from the natural air inlet and discharges the dirty air through the ventilation fan. The suction type sucks in fresh air through the ventilation fan and discharges the dirty air from the natural exhaust port. The combination type is that the suction and exhaust are completed by the ventilation fan, and the motor drives the fan blade to rotate and drive the airflow to exchange indoor and outdoor air. It is also called a ventilation fan. The purpose of ventilation is to remove indoor dirt. Air, adjust temperature, humidity and sensory effects, ventilation fans are widely used in homes and public places, but the functions of ventilation fans on the market are relatively single, and at the same time it is not easy to install, so an easy-to-install ventilation fan is needed to improve the above problems
