Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to an axial flow fan that can provide illumination. Background Technology

[0002] An axial fan is a type of fan that operates based on the axial airflow direction. Its working principle is mainly to generate airflow by rotating blades. The blades push the air to flow in the same direction as the axis, thereby realizing functions such as air delivery, ventilation, and cooling. It is widely used in industrial ventilation, building ventilation, cooling systems, aerospace, agricultural temperature control and other fields.

[0003] As application scenarios continue to expand, some axial fans are being used in dimly lit environments, such as basements, underground parking lots, mines, and inside industrial equipment. These applications create lighting requirements for axial fans, necessitating illumination to assist in determining whether the ground is dry, the degree of dust removal, ventilation efficiency, whether the axial fan is operating normally, the condition of the internal ductwork, and even the effectiveness of heat dissipation. Existing axial fans used in these scenarios typically require additional lighting equipment, which presents inconvenience. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an axial flow fan that can be illuminated, with an illumination unit provided on the air outlet side of the axial flow fan to illuminate the space in the direction of the axial flow fan's airflow, which facilitates the normal use and maintenance of the axial flow fan in dim scenes, and utilizes the airflow of the axial flow fan to dissipate heat from the illumination unit, thereby slowing down the aging of the illumination unit due to its own heat generation.

[0005] An illuminated axial flow fan includes a fan casing, a fixed cylinder, a support rib, a motor, fan blades, an illumination bracket, an illumination unit, and an illumination switch unit. The fixed cylinder and the support rib are both located inside the fan casing. The two ends of the support rib are fixed to the outer wall of the fixed cylinder and the inner wall of the fan casing, respectively. The motor is fixed to the fixed cylinder, with one end of the motor having an output shaft facing the air inlet side of the fan casing. The fan blades are drive-connected to the output shaft of the motor. The illumination bracket is located near the air outlet side of the fan casing and is fixed to the fan casing. The backlight side of the illumination unit is fixed to the illumination bracket, and the light-emitting side of the illumination unit faces the air outlet side of the fan casing. The illumination switch unit is located outside the fan casing and is fixed to the fan casing. The illumination switch unit is electrically connected to the illumination unit.

[0006] The axial flow fan with illumination described in this utility model has an illumination unit installed on the air outlet side of the axial flow fan to illuminate the space in the direction of the axial flow fan's airflow, which facilitates the normal use and maintenance of the axial flow fan in dimly lit scenes. Furthermore, the airflow of the axial flow fan is used to dissipate heat from the illumination unit, slowing down the aging process of the illumination unit due to its own heat generation.

[0007] Furthermore, it also includes a heat sink, which is located between the lighting unit and the lighting bracket. One side of the heat sink is flush against the lighting unit, and the other side is fixed to the lighting bracket. By providing a heat sink, the heat dissipation efficiency of the lighting unit is improved, further slowing down the aging process of the lighting unit due to its own heat generation.

[0008] Furthermore, it also includes a heat-conducting sheet located between the lighting unit and the heat sink, with both sides of the heat-conducting sheet respectively in close contact with the lighting unit and the heat sink. The heat-conducting sheet improves the heat transfer efficiency between the lighting unit and the heat sink, thereby improving the heat dissipation efficiency of the lighting unit and further slowing down the aging process of the lighting unit due to its own heat generation.

[0009] Furthermore, the lighting bracket includes support legs and a top plate. The two ends of the support legs are fixed to the top plate and the air duct, respectively. The top plate has ventilation holes. The backlight side of the lighting unit is fixed to the top plate and covers the ventilation holes. A gap is provided between the lighting unit and the ventilation holes. The ventilation holes on the top plate and the gap between the lighting unit and the top plate allow for smooth airflow between them, improving the heat dissipation efficiency of the lighting unit.

[0010] Furthermore, it also includes a light guide plate, which is located between the lighting unit and the air outlet side of the air duct, and is fixed to the lighting bracket. The light guide plate improves the uniformity of the lighting light, concentrates the light, and reduces light loss, thereby ensuring the lighting effect. It also reduces the energy consumption of the lighting unit, thus reducing the heat generated by the lighting unit.

[0011] Furthermore, it also includes a lampshade, which is fixedly mounted on the light-emitting side of the lighting unit. The lampshade serves to protect against water, insects, and dust, preventing damage to the lighting unit from moisture, insects, dust, etc., and preventing a deterioration in lighting and heat dissipation effects due to moisture, insects, dust, etc.

[0012] Furthermore, the lighting unit is arranged along the axis of the motor's output shaft. This arrangement minimizes any interference or obstruction of the airflow from the axial fan.

[0013] Furthermore, it also includes a fan bracket, which comprises a support portion and two connecting portions. One end of each connecting portion is fixed to the support portion, and the air duct is located between the other ends of the two connecting portions. The other end of each connecting portion is pivotally connected to the outer wall of the air duct. The fan bracket facilitates adjustment of the angle of the axial fan's airflow and the lighting.

[0014] Furthermore, it also includes a protective box. The lighting switch unit includes a lighting button and a lighting switch circuit board. The lighting switch circuit board is located inside the protective box, and the lighting button passes through the protective box and is electrically connected to the lighting switch circuit board. The protective box serves two purposes: firstly, it protects the lighting switch circuit board, and secondly, it acts as a fireproofing element. When the lighting switch circuit board catches fire, the protective box limits the spread of the fire and may even extinguish it.

[0015] Furthermore, it also includes a socket located outside the air duct, which is electrically connected to the motor, the lighting unit, and the lighting switch unit. Providing a socket allows workers to directly connect other tools to the axial fan for operation, improving the convenience of using and maintaining the axial fan.

[0016] The beneficial effects of this application are as follows:

[0017] 1. Install a lighting unit on the air outlet side of the axial fan to illuminate the space in the direction of the axial fan's airflow, which facilitates the normal use and maintenance of the axial fan in dimly lit scenes.
