Description
Technical field
The utility model relates to blower fan technical field, particularly relates to new medical level blower fan.
Background technique
At present, the essential characteristic of blower fan is: blower fan is the mechanical energy relying on input, improve gas pressure to supply gas side by side the machinery of body, it is a kind of driven fluid machinery, blower fan is widely used in household electric appliance, the ventilation of the equipment such as Medical Instruments, cooling, dedusting, in addition, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, air inducing, cooling, dust discharge and cooling are also the large ample scopes for abilities of blower fan one, the noise that traditional fan delivery is large is large, energy loss is large, each advantage can not perfectly be combined on same blower fan, science and technology is utilized to make up the frontier that this shortcoming is blower fan technical development.
Model utility content
Technical problem to be solved in the utility model, it is the technical deficiency for above-mentioned existence, provide new medical level blower fan, comprise A to give vent to anger end cap, impeller, impeller back-up ring, B gives vent to anger end cap, negative and positive groove, air inlet end cap, blade, the impeller of blower fan adopts forward-type, there are 12 blades, blade has tortuosity streamlined and suitable preferably, the blast of blower fan, air quantity is large, life-span is long, noise is low, run stability is good, ensure that fan has enough large air quantity and higher efficiency on the one hand, also reduce energy loss on the other hand, reduce noise, flow blower casing passes through casting, structure is simple, intensity is higher, beautiful shape.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: comprise give vent to anger end cap, impeller, impeller back-up ring, B of A and to give vent to anger end cap, negative and positive groove, air inlet end cap, blade; A end cap of giving vent to anger is matched by negative and positive groove with impeller; Impeller is socketed with impeller back-up ring and coordinates; Impeller back-up ring and B end cap of giving vent to anger is matched by negative and positive groove; A end cap and B end cap of giving vent to anger of giving vent to anger is connected by negative and positive groove; B end cap of giving vent to anger is connected by negative and positive groove with air inlet end cap; The central axis of impeller back-up ring and the central axes of air inlet end cap.
Further optimization the technical program, described impeller adopts forward-type impeller.
Further optimization the technical program, described impeller is that center of circle discrete type is evenly provided with 12 blades with medial axis.
Further optimization the technical program, described blade is bending, streamline vane.
Compared with prior art, the utility model has the following advantages: 1, impeller adopts forward-type impeller, and shape and the air moving direction under centrifugal action is completely contrary, the tortuosity of blade is less, shock between air and blade is very little, energy loss and noise less, efficiency is higher; 2, impeller adopts 12 blades, adds the flabellum number of blade, and blade can make air throw away from impeller with higher flow velocity, under the condition that rotating speed is constant, increases the air quantity of fan, makes air less at the static pressure at fan outlet place; 3, impeller adopts bending, streamline vane, and making it tortuosity streamlined and suitable preferably can improve fan efficiency greatly; 4, A end cap and B end cap of giving vent to anger of giving vent to anger is connected by negative and positive groove, and docking property is strong, good airproof performance.
Accompanying drawing explanation
Fig. 1 is the explosive decomposition figure of new medical level blower fan.
Fig. 2 is the blade wheel structure schematic diagram of new medical level blower fan.
In figure: 1, A gives vent to anger end cap; 2, impeller; 3, impeller back-up ring; 4, B gives vent to anger end cap; 5, negative and positive groove; 6, air inlet end cap; 7, blade.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with embodiment also with reference to accompanying drawing, the utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Embodiment one: shown in Fig. 1-2, comprises give vent to anger end cap 1, impeller 2, impeller back-up ring 3, B of A and to give vent to anger end cap 4, negative and positive groove 5, air inlet end cap 6, blade 7; A end cap 1 of giving vent to anger is matched by negative and positive groove 5 with impeller 2; Impeller 2 is socketed with impeller back-up ring 3 and coordinates; Impeller back-up ring 3 and B end cap 4 of giving vent to anger is matched by negative and positive groove 5; A end cap 1 and B end cap 4 of giving vent to anger of giving vent to anger is connected by negative and positive groove 5; B end cap 4 of giving vent to anger is connected by negative and positive groove 5 with air inlet end cap 6; The central axis of impeller back-up ring 3 and the central axes of air inlet end cap 6; Impeller 2 adopts forward-type impeller; Impeller 2 is that center of circle discrete type is evenly provided with 12 blades 7 with medial axis; Blade 7 is bending, streamline vane.
Working principle: after energising, connects impeller 2 by negative and positive groove 5 and rotates, formation low pressure area, center portion, outside air enters low pressure position by air inlet end cap 6, carrys out the pressure of balanced gas, forms air-breathing, unnecessary gas can be discharged to around impeller 2 by blade, makes it to become zone of high pressure, and then is discharged by A end cap 1 of giving vent to anger by gas, form exhaust, because air outlet is comparatively large, the static pressure of giving vent to anger is less, blast, the air quantity of U65 blower fan are large, and efficiency is high, and the life-span is long, noise is low, and run stability is good.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.Should be understood that, above-mentioned embodiment of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
