Abstract
The utility model discloses a draught fan which comprises a shaft, a support, an impeller arranged on the shaft and a machine shell. The shaft is a fixed shaft and is connected with the impeller through a bearing, the support comprises a shaft sleeve fixedly connected with the shaft and a shaft bar connected to the shaft sleeve, the machine shell is movably connected with the centrifugal end of the impeller, a cleaner is further arranged between the impeller and the shaft bar, the cleaner comprises a cleaning blade and a cleaning bar, and the cleaning blade and the impeller are identical in structure. The cleaner is arranged between the impeller and the shaft bar, when retention dust exists on the impeller, the cleaner can be rotated to clean the impeller, the dust drops in the machine shell, due to the fact that the machine shell and the centrifugal end of the impeller are movably connected, after the dust is cleaned, the machine shell can be taken down to discard the dust, the operation is simple, and the cleanliness degree is high.
Description
Technical field
The utility model relates to a kind of blower fan, is specifically related to a kind of blower fan of axial flow.
Background technique
The blower fan of types such as that existing blower fan mainly contains is centrifugal, axial flow, diagonal flow type and cross-flow type, axial fan is because simple in structure, solid and reliable, characteristics such as noise is little, the function range of choice is wide, be widely used in metallurgy, chemical industry, light industry, food, medical reaching, place ventilation or reinforcement heat radiations such as civil building.
Existing blower fan such as Chinese patent CN202073840U disclose a kind of blower fan on the market, comprise axle and the impeller that is loaded on this, and casing, and casing is core structure, and the centrifugal end of inner and impeller is solidly installed; Axle is stationary axle, and is connected with impeller by bearing.This blower fan is to have characteristics such as compact structure, and applied range.Yet, existing blower fan not during working procedure impeller tend to accumulate a lot of dusts, not only influence the blower fan overall appearance in the course of time, but also influence its working life.
The model utility content
The utility model is at the problem of the existing easy dust stratification dirt of blower fan, and purpose is to provide a kind of blower fan that can in time clean dust on the impeller.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of blower fan, comprise axle, support, be installed in impeller and casing on this, described axle is stationary axle, and be connected with described impeller by bearing, described support comprises the axle sleeve of fixedlying connected with axle and the axle bar that is connected on the axle sleeve, the centrifugal end of described casing and impeller flexibly connects, also be provided with cleaner between described impeller and the axle bar, described cleaner comprises cleaning blade and the cleansing bar identical with blade wheel structure.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in: be provided with cleaner between impeller and axle bar, when on the impeller laying dust being arranged, can rotate cleaner impeller is cleaned, dust is fallen in the casing, because the centrifugal end of casing and impeller flexibly connects, after having cleaned dust, casing can be taken off, outwell dust, simple to operate, turbidity test are high.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the structural representation of cleaner.
Among the figure: casing 1, axle 2, bearing 3, impeller 4, axle sleeve 5, support 6, axle bar 7, cleaner 8, cleaning blade 81, cleansing bar 82.
Embodiment
Below in conjunction with drawings and the specific embodiments structure of the present utility model is described further.
As shown in Figure 1 and Figure 2, a kind of blower fan, comprise axle 2, support 6, be installed in this impeller 4 and casing 1 on 2, described axle 2 is stationary axle, and is connected with described impeller 4 by bearing 3, described support 6 comprises the axle sleeve 5 of fixedlying connected with axle 2 and is connected axle bar 7 on the axle sleeve 5, the centrifugal end flexible connection of described casing 1 and impeller 4, also be provided with cleaner 8 between described impeller 4 and the axle bar 7, described cleaner 8 comprises cleaning blade 81 and the cleansing bar 82 identical with impeller 4 structures.
When on the impeller 4 laying dust being arranged, owing to be provided with cleaner 8 between impeller 4 and axle bar 7, when blower fan rotated, cleaner 8 kept static, and blower fan is when quitting work, can clean by 8 pairs of impellers 4 of hand rotation cleaner, dust is fallen in the casing 1, because the centrifugal end of casing 1 and impeller 4 flexibly connects, after having cleaned dust, casing 1 can be taken off, outwell dust, simple to operate, turbidity test are high.
