Be provided with dust filter 27 in the above-mentioned dust storage chamber 25, provide the fan electromotor of suction structure 28 and be provided with in the Machine Room 26.
As shown in Figure 2, said fans electric machine structure 28 comprises: frame 31, motor 34, inhalator 37, inhaler cap 38 and guide type shoe 35.
Above-mentioned motor 34 comprises: stator 32, rotor 33 and motor shaft 36; Above-mentioned motor shaft 36 is pressed into the endoporus of the rotor 33 of motor 34, and utilizes nut 39 to be fixed in the end of motor 34.
Be provided with the guide type shoe 35 that is used for guiding air flow motor 34 inboards that are inhaled between above-mentioned inhalator 37 and the motor 34, the front end of guide type shoe 35 is connected with inhaler cap 38.
As shown in Figure 3, above-mentioned motor shaft 36 ends are used for fastening nut 39 threads.
Above-mentioned thread is and the opposite thread of inhalator 37 direction of rotation to its objective is to prevent that nut 39 from becoming flexible when inhalator 37 rotations.
By the vacuum cleaner with conventional fan electric machine structure that above-mentioned parts are formed, after energising, the motor shaft 36 of motor 34 begins rotation, drives inhalator 37 rotations that are fixed on the motor shaft 36 and produces suction, and by suction inlet dust, foreign matter are sucked.Dust that is inhaled into and foreign matter filter by filter 27, pass through inhalator 37, guide type shoe 35 successively through filtered air, blow to motor 34, are discharged into the dust catcher outside behind the cooling motor.
The defective of the conventional vacuum dust catcher that is made of above-mentioned parts is: when inhalator with air when motor blows, air successively rubs with the inhalator and the guide type shoe of rotation at a high speed, makes the air themperature rising, thereby motor is fully cooled off.
If a cooling electric fan is set in addition for addressing the aforementioned drawbacks, will corresponding increase manufacturing cost.
Summary of the invention
Technical problem to be solved by this invention is: a kind of vacuum cleaner that is equipped with novel fan electromotor structure is provided, make the air that is inhaled at first pass through motor, be discharged to the casing outside through guide type shoe and inhalator then, thereby motor is fully cooled off.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: comprising: casing, suction inlet, outlet, dust storage chamber, Machine Room, dividing plate, filter and fan electromotor structure.Described fan electromotor structure comprises: frame, motor, inhalator, guide type shoe and inhaler cap.Described motor comprises: stator, rotor and motor shaft, the central bore of motor shaft and rotor closely cooperates.
A through hole is arranged on the described dividing plate.
Described fan electromotor structure is positioned at the Machine Room, and motor is installed in the front end of fan electromotor structure frame, and guide type shoe, inhalator and inhaler cap are installed in the rear end of fan electromotor structure frame from inside to outside successively; The through hole on the described dividing plate is closed in the position of the front end of fan electromotor structure frame.
Described motor shaft rearward end is provided with the left-hand thread opposite with the inhalator direction of rotation.
The invention has the beneficial effects as follows: because inhalator is arranged on the rear end of fan electromotor structure, and motor closes on the through hole on the dividing plate between dust storage chamber and the Machine Room, thereby makes the cold air that is inhaled at first be used for cooling motor, has improved cooling effectiveness greatly.
And owing to be provided with the left-hand thread opposite with the motor direction of rotation in the rearward end of motor shaft, thereby nut is loosening can prevent the inhalator rotation time.

The specific embodiment
Below in conjunction with the drawings and specific embodiments this present invention is described in further detail:
As shown in Figure 4, a side of vacuum cleaner casing 23 of the present invention is provided with suction inlet 21, and its opposite side is provided with outlet 22, and the inside of casing 23 is provided with dust storage chamber 25 and the Machine Room 26 that is separated by dividing plate 24, and dividing plate 24 is provided with through hole 24a; The inside of dust storage chamber 25 is provided with filter 27, and filter 27 can be collected in the dust from suction inlet 21 inhaled airs in the dust bag, passes air into Machine Room 26; The inside of Machine Room 26 is provided with fan electromotor structure 28, so that suction to be provided.
As shown in Figure 5, described fan electromotor structure 28 comprises: frame 31, motor 34, inhalator 37, guide type shoe 35 and inhaler cap 38.Described motor comprises: stator 32, rotor 33 and motor shaft 36, motor shaft 36 closely cooperates with the central bore of rotor 33.
