The utility model discloses in, the motor is located outside the wind field that the fan formed, and is located the motor installation shell, and inside the dust in the wind field was difficult for adhesion and motor or entered into the motor to realize preventing dust of fan.
Description
Technical Field
The utility model relates to a fan, more specifically say, relate to a dustproof fan.
Background
Most of the existing fans used in daily life are in two structural forms of axial flow fans and volute fans. The two types of fans are characterized in that the motor is positioned in a wind field formed by the fans. Because there is the dust in the air, the fan is used for a long time, and the dust in the air can the adhesion with the outside of motor, influences the heat dissipation of motor, enters into inside the motor even, influences the lubrication etc. of motor rotor bearing and influences the normal work of motor and uses.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that the motor of current fan advances the dust easily and influences the problem of normal use, and provides a dustproof fan, avoids the dust in the wind field that the fan during operation fan formed to enter into the motor.
The utility model discloses a realize that the technical scheme of its purpose is like: the utility model provides a structure dustproof fan, includes the terminal flabellum of motor, fixed mounting motor shaft, its characterized in that still includes the air duct pipe, fixes at the outside motor installation shell of air duct pipe, motor fixed mounting is in the motor installation shell, the pivot of motor passes the lateral wall of air duct pipe and stretches into in the air duct pipe. The utility model discloses in, the motor is located outside the wind field that the fan formed, and is located the motor installation shell, and inside the dust in the wind field was difficult for adhesion and motor or entered into the motor to realize preventing dust of fan.
In the above dustproof fan, the air duct pipe is arc-shaped, and further, the air duct pipe is a 90-degree arc pipe.
In the dustproof fan, the air duct pipe is a pipe with a uniform cross section.
In the dustproof fan, the tail end of the motor rotating shaft installation fan blade is close to the air outlet of the air duct pipe and is positioned at the central part of the air duct pipe.
In the dustproof fan, the hole on the air duct pipe for the motor rotating shaft to penetrate is internally provided with the dustproof ring.
In the dustproof fan, the outer surface of the motor installation shell is provided with the raised radiating fins.
Compared with the prior art, the utility model, the motor of fan is located the wind field outside that the fan formed, and inside dust in the wind field can not entered into the fan, it is dustproof to realize the fan.
Drawings
Fig. 1 is a schematic structural view of the dustproof fan of the present invention.
Fig. 2 is a schematic sectional view of the dustproof fan of the present invention.
Fig. 3 is a schematic view of the structure of the motor mounting housing of the dustproof fan of the present invention.
Part names and serial numbers in the figure:
the dust-proof device comprises a motor 1, a dust ring 2, an air duct pipe 3, a bolt 4, a motor mounting shell 5 and fan blades 6.
Detailed Description
The following description of the embodiments refers to the accompanying drawings.
As shown in fig. 1 to 3, the dustproof fan in this embodiment includes a motor 1, a fan blade 6 fixedly mounted at a terminal of a motor rotating shaft 11, an air duct pipe 3, and a motor mounting case 5 fixed outside the air duct pipe 3, wherein a raised heat dissipation fin is disposed on an outer surface of the motor mounting case 5.
The air duct pipe 3 is a 90-degree arc pipe, and is a pipe with an equal cross section, and one end of the air duct pipe is used for air inlet and the other end of the air duct pipe is used for air outlet.
The motor 1 is fixedly arranged in the motor mounting shell 5 through a bolt 4, the motor mounting shell 5 is fixedly connected with the air duct pipe in an assembling way, a rotating shaft 11 of the motor 1 penetrates through the side wall of the air duct pipe 3 to extend into the air duct pipe 3, and the tail end of a fan blade mounted on the rotating shaft 11 of the motor is close to the air outlet of the air duct pipe 3 and is positioned at the central part of the air duct pipe 3. And a dustproof ring 2 is arranged in a hole on the air duct pipe 3 for the motor rotating shaft 11 to penetrate through.
Compared with the existing fan, the dustproof fan in the embodiment has the advantages that the motor of the fan is located outside a wind field formed by the fan, dust in the wind field cannot enter the fan, and the dustproof effect of the fan is achieved.
