Background
The existing fan air outlet and the fan main body are mostly integrally formed, and the fan outlet wind shielding grille is often fixed in the fan air outlet in a threaded connection or clamping connection mode. The design mainly has two defects, one is that the curved surface of the mould of the fan main body is more, the cost is higher, and if the fan main body of a non-key part can be reduced, the cost of the mould can be reduced. Secondly, the installation of fan is troublesome, need block the grid to threaded connection's position after, just can connect through threaded connection's mode, and in actual assembly line operation, the process is a bit too much, and is consuming time long, has influenced holistic assembly efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims at providing a cost is lower before comparing, the better fan of result of use.
The utility model provides a fan, including fan housing, fan air outlet department on the fan housing is provided with a fan air outlet cover, fan housing with fan air outlet cover forms for the body coupling that divides, be provided with fixed recess on the fan air outlet, be provided with the fixing clip hole on the fixed recess, fan air outlet cover is provided with fixed fixture block behind one's back, be provided with on the fixed fixture block can with the fixing clip tooth of fixing clip hole adaptation, through the fixing clip hole with fixing clip tooth joint, thereby will fan air outlet cover joint is in on the fan housing.
Preferably, the fixing groove is annular, the fixing clamp holes are divided into two groups which are oppositely arranged on the fixing groove, and the number of the fixing clamp holes of one group of the fixing clamp holes is three.
Preferably, the fixing clip hole is disposed on the fixing groove through the fixing groove.
Preferably, the fixing clamping block is also annular, and the number and the position of the fixing clamping teeth on the fixing clamping block are consistent with those of the fixing clamping holes.
Preferably, a grille is arranged on the inner side of the fan air outlet sleeve.
The utility model discloses a fan's beneficial effect does:
the utility model discloses a fan includes fan housing, and fan air outlet department on the fan housing is provided with a fan air outlet cover, and fan housing and fan outlet cover form for the body coupling that divides.
