To 360 ° of waterproof.
Technical scheme: for solving above-mentioned technical problem, a kind of waterproof machine of the present invention, be connected with body including body
Electric machine casing, described electric machine casing rear end is connected with motor rear cover, and electric machine casing rear end is provided with air intake passage, before electric machine casing
End is provided with air-out passage, is provided with air inlet, is provided with splash guard, wind above air inlet in motor rear cover below motor rear cover
Entered in air intake passage along splash guard by air inlet.
Preferably, described splash guard comprises the first waterproof curved surface, the second waterproof curved surface, first waterproof curved surface one end extends
There is erecting bed, erecting bed is connected with motor rear cover, the first waterproof curved surface other end is connected with one end of the second waterproof curved surface, second
The outer surface of the waterproof curved surface other end is the concave arc shape stretching out.
Preferably, described air inlet is provided with screen pack, screen pack is provided with filter paper, filter paper because there is filter opening,
So wind can not be affected entering in motor, and a large amount of water droplets can be slowed down and enter in motor.
Preferably, dust block board is alternately provided with described motor rear cover and splash guard, dust block board and splash guard are respectively mounted
There is absorbent wool, by entering into eolian " s " type in air intake passage, and because dust block board is provided with absorbent wool, can be by
Moisture in wind and marble dust adsorb in absorbent wool, enter into air-dried dry in motor and without powder, improve electric
The security performance of machine, extends the service life of motor.
Beneficial effect: the waterproof machine of the present invention, even if by being provided with splash guard so that water droplet enters in air inlet
Air inlet, due to the stop of splash guard, will not enter in air intake passage；And due to being provided with filter paper in air inlet, block
Substantial amounts of water droplet enters, and the water droplet of only minority enters in motor rear cover；Alternately it is provided with due on motor rear cover and splash guard
Dust block board, dust block board is provided with absorbent wool, by entering in air intake passage of eolian " s " type, because dust block board is provided with suction
Water cotton, can adsorb the moisture in wind and marble dust in absorbent wool, enter into air-dried dry in motor and also without
Powder, improves the security performance of motor, extends the service life of motor.
Brief description
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the partial sectional view of Fig. 1；
Fig. 3 is the structural representation of the splash guard in Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings the present invention is further described.
As shown in Figure 1 to Figure 3, a kind of waterproof machine, the electric machine casing 2 being connected with body 1 including body 1, described motor
Housing 2 rear end is connected with motor rear cover 3, and electric machine casing 2 rear end is provided with air intake passage 4, and electric machine casing 2 front end is provided with air-out and leads to
Road, is provided with air inlet 6 below motor rear cover 3, be provided with splash guard 5 in motor rear cover 3 above air inlet 6, wind pass through into
Air port 6 enters in air intake passage 4 along splash guard 5.
In the present invention, described splash guard 5 comprises the first waterproof curved surface 51, the second waterproof curved surface 52, the first waterproof curved surface
51 one end are extended with erecting bed, and erecting bed is attached by screw thread with motor rear cover 3, the first waterproof curved surface 51 other end and
One end of two waterproof curved surfaces 52 connects, and the appearance periphery of the second waterproof curved surface 52 other end is the concave arc shape stretching out.
In the present invention, at described air inlet 6, screen pack is installed, screen pack is provided with filter paper, filter paper is because there is filter
Hole enters in motor it is possible to not affect wind, and can slow down a large amount of water droplets and enter in motor.
In the present invention, described splash guard 5 is arranged on motor rear cover 3, and motor rear cover 3 and splash guard 5 are alternately installed
Have and be mounted on absorbent wool on dust block board 7, dust block board 7 and splash guard 5, wind is led to by the air intake that enters into that air inlet 6 becomes " s " type
In road 4, and because splash guard 5 is provided with absorbent wool, the moisture in wind and marble dust can be adsorbed in absorbent wool,
Enter into air-dried dry in motor and without powder, improve the security performance of motor, extend the service life of motor.
Motor is made up of motor rear cover 3, electric machine casing 2, drive end bearing bracket and corresponding electric elements substantially, simultaneously for guaranteeing
The temperature rise of motor not can exceed that setting, and motor generally all can be provided with air inlet 6, fan blade and air outlet, motor work
When making, fan blade rotates with motor shaft, and cold wind enters from motor rear cover 3, and motor braking produces the rotation through fan blade for the heat energy by heat
Wind is sent at drive end bearing bracket, and our seen motor rear covers 3 are all the fronts that air outlet slabbing is located at motor rear cover 3,
