As shown in Figure 4, according to an embodiment of the present utility model, the motor cover 100 of dust catcher may further include the 3rd motor cover 70 with the second motor cover 20 one, the 3rd motor cover 70 can be set in the outside of the second motor cover 20 and and the second motor cover 20 between limit in the second air channel 402, the three motor cover 70 that are communicated with the first air channel 401 by the second gas outlet 21 and be formed with the air outlet departing from the second gas outlet 21.
Alternatively, the 3rd motor cover 70 can comprise one deck cover body, as shown in Figure 4.Preferably, the distance range between the 3rd motor cover 70 and the second motor cover 20 is between 5mm-40mm.Certainly, the utility model is not limited to this, in other optional embodiment of the present utility model, the 3rd motor cover 70 comprises from inside to outside multilayer cover body successively, for example, the 3rd motor cover 70 can comprise the first sub-cover body and the second sub-cover body, now, between the first sub-cover body and the second sub-cover body, can also there is the 3rd air channel, with similar in above-described embodiment, the 3rd air channel can be communicated with the second air channel 402, and air outlet is located on the second sub-cover body to gas mobile in the 3rd air channel is discharged.Preferably, in the 3rd motor cover 70 distance range between every layer of cover body between 5mm-40mm.
As shown in Figure 1, according to an embodiment of the present utility model, the first gas outlet 11 comprises the first venthole of multiple strips that in axial direction extend, the second gas outlet 21 comprises multiple the second ventholes, and multiple the second ventholes are uniformly distributed along the axial and circumferential directions on the part perisporium of the second motor cover 20.Preferably, the second gas outlet 21, that is to say relative to setting in the radial direction with the first gas outlet 11, multiple the second ventholes with multiple the first ventholes relative to setting in the radial direction.Certainly, the first gas outlet 11 and the second gas outlet 21 can also be respectively an opening.
In concrete preferred embodiment of the utility model, multiple the first ventholes are distributed on the half perisporium of the first motor cover 10, and multiple the second ventholes are distributed on second half perisporium of the second motor cover 20.Thus, air channel enough extends, thereby makes air-flow can have large as far as possible spatial stability to get off, and reduces noise.According to an embodiment of the present utility model, the first motor cover 10, the second motor cover 20 and coaxial setting of the 3rd motor 70 covers.
As shown in Figure 4, easy in order to describe, in the following description, be all described taking the 3rd motor cover 70 as one deck.Those skilled in the art are appreciated that in the time that the 3rd motor cover 70 comprises that from inside to outside successively two layers and two layers are with upper outlet body, its inner air flow with one deck cover body time air the type of flow similar, no longer itemize at this.
The first motor cover 10 is interior can be provided with the blower fan with motor, the air being sucked by blower fan enters in the first motor cover 10, inwall along the first motor cover 10 flows, and interior mobile from 11 to first air channels 401, the first gas outlet, then flow out and enter in the second air channel 402 from the second gas outlet 21 of the second motor cover 20, inwall along the 3rd motor cover 70 flow to air outlet, and flows out in exhaust apparatus below.Like this, by the first air channel 401 between the first to the 3rd motor cover 10,20,70 and the second air channel 402, the labyrinth type that has realized air-flow flows, extend the air channel length of Air Flow, enough spaces are provided and settle out therefore can to disorderly air-flow, thereby reduce flowing of air.And, due between the first to the 3rd motor cover because the motion of gas has formed relative vacuum, like this, can greatly reduce noise and vibration that air draught and motor when running itself produces, and then obtain better quiet or super-silent product.
Comprise the motor cover 100 of the utility model above-described embodiment according to dust catcher of the present utility model.
According to the dust catcher of the utility model embodiment, there is the motor cover 100 of the utility model above-described embodiment, the first motor cover 10 and the second motor cover 20 are structure as a whole, by coordinating motor wrapped up with motor front shroud 30, form a motor cover with sandwich construction, enhance productivity, reduce production costs.
Below referring again to Fig. 1-Fig. 4 to being specifically described according to the course of work of the dust catcher of the utility model embodiment, wherein comprise that taking the 3rd motor cover 70 one deck cover body describes as example.
First, electric machine rotation is in the interior generation negative pressure of the first motor cover 10, be drawn into mussily and be positioned at through hole 31 dust collect plant before with the air of dust, be filtered entering the front dust of through hole 31, air enters in the first motor cover 10 the then inwall along the first motor cover 10 and flows, and interior mobile from 11 to first air channels 401, the first gas outlet, then flow out and enter in the second air channel 402 from the second gas outlet 21 of the second motor cover 20, flow to air outlet along the inwall of the 3rd motor cover 70 and discharge.
Be all known for those of ordinary skills according to other formations of the concrete formation of integrating device in the dust catcher of the utility model embodiment and air inlet, exhaust apparatus and operation, be not described in detail here.
In the description of this description, the description of reference term " embodiment ", " some embodiment ", " illustrative examples ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.
