Abstract
A fan with a shell and a flow deflector split in structure comprises a stator (1), a rotor (2), a check valve (3), the shell (4), the flow deflector (5), a fan blade (6) and a shaft (7). The shaft (7) is located at the central axis of the rotor (2) which is connected to the shaft (7) in a pressed manner, the stator (1) is located on the outer side of the rotor (2) and is pressed in the flow deflector (5), the flow deflector (5) is in threaded connection with the shell (4), the fan blade (6) is connected with the shaft (7), a winding nested in a groove of the stator (1) is connected with a power supply, and each of the stator (1), the rotor (2), the check valve (3), the shell (4), the flow deflector (5), the fan blade (6) and the shaft (7) is located in the shell (4). The fan is simple in structure, convenient to mount, exchange and maintain and quite wide in market prospect.
Description
Technical field
The utility model relates to structural design and the applied technical field of blower fan, and it is the blower fan of Split type structure that a kind of housing and guide plate are provided especially.
Background technique
The blower fan generally adopting at present all adopts housing and guide plate integral structure, utilizes mould one-step die casting, and precision is lower, and the key propertys such as the air quantity of blower fan and blast are had a negative impact.And blower fan does not possess automatic protection function, when blower fan is worked, ubiquitous foreign matter enters and air inversion phenomenon.
People urgently wish to obtain the blower fan that the good housing of a kind of technique effect and guide plate are Split type structure.
Model utility content
It is good that order of the present utility model is to provide a kind of technique effect, the blower fan that housing and guide plate are Split type structure.
Described housing and guide plate are that the blower fan of Split type structure is constructed as follows: stator 1, rotor 2, one-way valve 3, housing 4, guide plate 5, flabellum 6 and axle 7; Described axle 7 is positioned at rotor 2 central axis, and rotor 2 is crimped on axle 7, stator 1 is positioned at rotor 2 outsides, stator 1 is fitted in guide plate 5, described guide plate 5 and with housing 4 be split-type structural, described guide plate 5 adopts and is threaded with housing 4, described flabellum 6 adopts and is threaded with axle 7, the winding embedding in stator 1 groove is connected with power supply, described stator 1, rotor 2, one-way valve 3, housing 4, guide plate 5, flabellum 6 and axle 7 are all positioned at housing 4, and described one-way valve 3 is fixed on one end of housing 4.
Described housing and guide plate are that the blower fan of Split type structure belongs to phase asynchronous blower fan.
When described housing and guide plate are the blower fan work of Split type structure, blower fan passes into three-phase 400Hz symmetrical current, thereby in air gap, set up rotating magnetic field, this rotating magnetic field induction electromotive force produce corresponding electric current in rotor bar in the rotor bar of short circuit, rotating magnetic field in this electric current and air gap interacts and produces electromagnetic torque, rotor rotates under the effect of this torque, and rotor drives flabellum rotation to produce Air Flow, realizes blower fan function.
The blower fan generally using at present all adopts housing and guide plate integrative-structure, utilizes mould one-step die casting.And the housing of the blower fan that housing described in the utility model and guide plate are Split type structure and guide plate adopt Split type structure, the two employing is threaded, so just can utilize machining mode to process housing and guide plate, effectively avoided that die-casting process precision is lower, die casting depanning success rate is lower and die cast after the problem of secondary mechanical processing.This structure can be generalized in the design of other blower fans.
Described housing and guide plate are that the air quantity of the blower fan of Split type structure is greater than 330m
3/ h, blast be greater than 2000Pa, rotating speed be greater than 20000rpm, can be under-55 ℃～85 ℃ conditions stable operation, simple in structure, be convenient to install, exchange and maintenance, there are boundless market prospects, there is comparatively huge economic value and social value.
Accompanying drawing explanation
Fig. 1 is the blower fan structure schematic diagram that housing and guide plate are Split type structure.
Fig. 2 is one-way valve structures schematic diagram.
