Description

Aspirator

Technical field

The utility model is about a kind of aspirator that is used for intake-gas.

Background technique

General aspirator is located in the place that needs a large amount of eliminating gases or smog, it mainly will desire at short notice gas or smog to be discharged rapidly, therefore it need increase the source of suction, and traditional aspirator as shown in Figure 1, it includes a casing (10) and and is located at the interior motor (20) of casing (10), this hollow box body (10) both sides are covered with a side cover (11) respectively, and side cover (11) wall has an air sucking mouth (12) respectively, edge, air sucking mouth (13) utilizes lock member (16) lock to be provided with the wind-guiding sheath (15) of a ring-type respectively, casing (10) end face has an exhaust port (13) again, and this motor (20) center that utilizes lock member (18) to be locked in the casing (10) has an output shaft (21), this output shaft (21) two ends are respectively equipped with in opposite directions a helical impeller (25), with gas is sucked by casing (10) air sucking mouth, both sides (12), and discharge by the exhaust port (13) of casing (10).But it only can come intake-gas or smog by the air sucking mouth (12) of both sides, and can't effectively satisfy the air draught efficient of motor (20), causes unnecessary energy waste, also has influence on its pumping efficiency.

Moreover the casing of aforementioned aspirator (10) forms with plate stamping, therefore its thickness is effective, the screw support force of the interlocking motor that is formed for (20) also is restricted, and otherwise reinforcement of need, invisible the difficulty that Zeng Jia System makes, and establish Shi Gengxu at lock and carry out contraposition and instrument screw lock, also increase its assembling and the inconvenience of disassembling, moreover aspirator in the running, motor can be because of the problem of firm effect deficiency, make casing (10) produce noise, reduce its whole quality and running efficiency because of vibrations.

For this reason; there have the dealer to develop to be a kind of as second; aspirator shown in three and four figure; this aspirator includes the housing (30) and of a die casting and is located at the interior motor (40) of housing (30); wherein motor (40) has an output shaft (42) that passes case (41) two ends; output shaft (42) two ends are respectively equipped with the helical runner (not shown) of agitating gas; be formed with a disk (45) on again in motor (40) case (41); disk (45) is provided with the equidistant arms (46) of plural number; arms (46) is provided with lock shaft (47); and housing (30) is made up of all right one way or the other half shell (31) that covers relatively; it is two parallel that two halves shell (31) has respectively; and the wheel cap (32) that keeps interval trough (33); two impellers of the suitable corresponding motor (40) of two-wheeled cap (32); the both sides of two halves shell (31) wheel caps (32) outside has corresponding half mouthful (34) again; form air sucking mouth (36) for covering relatively; make the gas can be by the air sucking mouth (36) of housing (30) both sides and middle interval trough (33) air inlet; moreover two halves shell (31) is formed with the axle sleeve (35) of corresponding motor (40) lock shaft (47) respectively on interval trough (33); pull for utilizing lock member to lock relatively; motor (40) can be fixed in the housing (30) of this two halves shell (31) shape composition; and the edge, air sucking mouth (36) that aforementioned half shell (31) both sides wheel caps (32) are formed utilizes lock member (39) to lock the wind-guiding sheath (38) that is provided with a ring-type respectively, with pilot gas; and provide protective action.

Though this aspirator can overcome the problem of aforementioned conventional air output deficiency, and improve whole running efficiency, but it is when the lock dress, need shilling arms (46) lock shaft (47) of motor (40) to aim at half shell (31) axle sleeve (35) of housing (30), utilize lock member and locking instrument to carry out the screw lock operation afterwards, and the lock of adding wind-guiding sheath (38) is established work, invisible has increased lock dress and the inconvenience and the puzzlement of disassembling, lock shaft (47) owing to motor (40) directly contacts with the axle sleeve (35) of housing (30) again, and lock together, therefore when motor (40) when running up, its vibrations can be delivered on the housing (30), and the phenomenon that lock member gets loose gradually may take place, further produce the problem of undesired vibration and running noise.

In other words, existing aspirator is when assembling, need carry out contraposition, when not only unrestrained, need utilize the instrument interlocking when assembling, invisible increases assembling and the inconvenience of disassembling again, it can't avoid the problem that vibrations get loose simultaneously, produced running noise, can't satisfy the demand of actual use, so necessity of further improvement is arranged.

Edge is in this, this creator is that the problem that faces at aforementioned aspirator is deeply inquired into, and by the Yan Fa that is engaged in related industry for many years Yu System makes experience, through the constantly research and development of effort, finally success create a kind of aspirator, use the inconvenience and the puzzlement that overcome the inconvenience of dismounting in the past and easily give birth to noise.

The model utility content

Therefore, the main purpose of this creation is providing a kind of aspirator, uses dismounting and the assembling that can be convenient to operator, and can reduce unnecessary vibrations and noise, and can promote its quality and value.

For this reason, this creation mainly sees through following technological means, come this creation of specific implementation projects and usefulness: this aspirator includes a housing and and is located at motor in the housing, wherein motor has the case of a coating stator and rotor, and motor has the output shaft that two ends pass case, the output shaft two ends are respectively equipped with an impeller, and housing is made up of an all right one way or the other upper half shell that covers relatively and a lower half shell, moreover housing on, it is two parallel that lower half shell has respectively, and middle wheel cap with interval trough, wherein the impeller of the corresponding aforementioned motor of cap is taken turns in both sides, go up again, in the wheel cap of lower half shell both sides, the outside has half mouthful that is communicated with inside respectively, can keep supplying for half mouthful, lower half shell covers the back relatively and forms the air sucking mouth, and on, the lower half shell top is formed with respectively for double mouthful of the phase that covers the formation exhaust port;

Motor case outer rim is formed with one or more fixed plate, and on the housing, lower half shell has the one or more folder part of pulling respectively on interval trough, this folder part of pulling has a clip slot for the corresponding fixed plate of clamping.

By this, see through representing of this creation aforementioned techniques means, allow the shell block of this creation can utilize plural number to press from both sides the direct clamping motor of part of pulling, and need not to carry out the interlocking of contraposition and instrument, significantly promote the convenience of dismounting, and the unlikely phenomenon that gets loose arbitrarily, and can reduce unnecessary vibrations and noise, can effectively increase the surcharge of product, and promote its economic benefit.

For making your juror can further understand formation, feature and other purposes of this creation, below be some preferred embodiments of lifting this creation, and cooperate graphic detailed description as after, allow simultaneously and be familiar with this technical field person and can specifically implement.
