Utility model content
The purpose of this utility model is to provide a kind of crossflow fan so that the motor for impeller rotation has certain
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of crossflow fan, including impeller, connect with impeller connecting shaft, for the motor of impeller high-speed rotation,
The motor is provided with close to one end of connecting shaft protrusion to be held and bearing cap that the shaft of power supply machine is worn for lid sympodium, described
Fixing sleeve is equipped with protective case, and the trapezoidal setting of interior diameter of the protective case on bearing cap, and the protective case is far from bearing cap
The through-hole worn for shaft is offered at the center of end face, be arranged in the shaft with shaft rotate synchronously and interior diameter be in
The axle sleeve of trapezoidal shape, and the one end of the protective case far from bearing cap is embedded in axle sleeve, the protective case is embedded in axle sleeve
Side circumferentially offer the collecting tank for collecting liquid water.
Using the above scheme, the setting of the protective case of the trapezoidal shape of internal diameter, to a certain extent to flowing into the liquid inside motor
State water has certain inhibition；The setting of collecting tank so that fall surface of the liquid water on the protective sleeve along protective case
Gradually it is collected into collecting tank；The setting of axle sleeve, one further hinder liquid water to enter inside motor along shaft, secondly
During impeller high-speed rotation, axle sleeve hinders dust to enter the inside of motor along shaft to a certain extent, improves motor
Preferably, the overall diameter of the protective case is in setting of successively decreasing successively along bearing cap to impeller direction.
Using the above scheme, the overall diameter of protective case successively decreases successively, convenient for falling within the liquid water on protective case surface along table
Face is faster flowed into collecting tank, accelerates gathering speed of the collecting tank to protective case surface liquid water to a certain extent.
Preferably, the impeller is horizontally arranged with several, and several impellers are parallel to each other.
Using the above scheme, the setting of impeller parallel to each other increases the intake of crossflow fan in same time and goes out
Preferably, the fixed plate and fixed block for fixing impeller and motor are provided on the outside of the impeller, and it is described
Several ventilation holes are offered in fixed plate.
Using the above scheme, the setting of ventilation hole has certain cooling effect, and then prevents crossflow fan in work
In the process, the phenomenon that temperature increases and then influences the service life of impeller on impeller is avoided.
Preferably, several described ventilation holes are parallel to each other, and the ventilation hole is laterally opened in fixed plate.
Using the above scheme, ventilation hole is laterally arranged, and in same time better heat-radiation effect, ventilation hole is set in parallel,
One has certain aesthetics, secondly being easy to open up ventilation hole by machine in operating personnel.
Preferably, the ventilation hole is arranged in long waist shaped.
Using the above scheme, the ventilation hole excellent in heat dissipation effect of long waist shaped, secondary aperture shape is relatively common, and then machine-shaping letter
It is single, conveniently, and the setting of ventilation hole size dimension, prevent the finger imbedding and contact of human body to impeller, therefore with certain peace
Preferably, end face of the fixed block far from impeller, which is screwed, is useful for the protection of protection control panel
Using the above scheme, the setting of protective shell there is certain protection to make the control panel being fixed in fixed plate
With, it prevents from surprisingly touching control panel during transport and then causes certain breakage to control panel, raising crossing current
The using effect of wind turbine.
Preferably, the corner of the fixed plate is arranged in rounding.
Using the above scheme, the setting of rounded corner so that fixed plate prevents sharp during installation or transport
Turning surprisingly hurts staff.
In conclusion the utility model has the advantages that：
1, the setting of protective case, collecting tank, the water to falling within protective case upper surface have certain collecting effect, secondly very
It hinders rainwater to be entered inside motor along shaft in big degree, and then improves making for motor on crossflow fan to a certain extent
Use the service life；
2, the setting of axle sleeve, works in coordination with protective case, further liquid water is hindered to be entered inside motor along shaft,
Simultaneously during impeller high-speed rotation, prevents dust from entering inside motor, improve the using effect of motor.

Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, 2, a kind of crossflow fan disclosed in the present embodiment, including impeller 1, turn at a high speed for impeller 1
Dynamic motor 3, fixed plate 10 and fixed block 14 for fixing impeller 1 and motor 3.
As shown in Fig. 2, fixed plate 10 is set to the surrounding of impeller 1, and the corner of fixed plate 10 is arranged in rounding.It is fixed
Block 14 is disposed in proximity to one end of motor 3, and fixed block 14 is square setting, and fixed block 14 is perpendicular to fixed plate 10.Fixed block
14 end faces far from impeller 1 are provided with the control panel 12 for controlling motor 3, one end spiral shell of the fixed block 14 far from impeller 1
Line is fixed with the protective shell 13 that certain protective role is played to control panel 12.
As shown in Fig. 2, the ventilation hole 11 that several are in long waist shaped setting is offered on 10 horizontal direction of fixed plate, several
Ventilation hole 11 is parallel to each other, and the size of ventilation hole 11 make human body finger can not imbedding and contact to impeller 1, therefore improve
The safety of crossflow fan.
As shown in Figure 2,3, motor 3 is extended with shaft 8 close to one end of impeller 1, and shaft 8 is rotated with for impeller 1
Connecting shaft 2 connect.Motor 3 is provided with the bearing cap 4 worn for shaft 8 close to one end of impeller 1, fixing sleeve on bearing cap 4
The trapezoidal shape of interior diameter equipped with protective case 5, and protective case 5 is arranged.Protective case 5 opens up at the center far from 4 one end of bearing cap
There are the through-hole 6 worn for shaft 8, and 6 rounded setting of through-hole.
As in Figure 2-4, the overall diameter of protective case 5 is arranged along motor 3 to impeller 1 in the shape that successively decreases successively, and protective case 5
One side close to impeller 1 circumferentially offers the collecting tank 9 for collecting liquid water.Turn synchronous with shaft 8 is arranged in shaft 8
Dynamic axle sleeve 7, and the interior diameter trapezoidal shape setting of axle sleeve 7, protective case 5 is far from bearing cap 4 and offers one end of collecting tank 9
It is embedded in axle sleeve 7.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but
