As a kind of improvement project, be respectively arranged with convex tendon on the relative internal face of said casing, said convex tendon is connected to the both sides of said flexible holder respectively.
As a kind of improvement project, said motor is laterally placed.
As a kind of improvement project, said motor only by the front end of motor and said flexible holder against with the rear end of motor through snubber block and said rear wall against.
As a kind of improvement project, said supporting seat offers groove, and said support portion is stuck in this groove.
As a kind of improvement project; Said casing comprises accommodating chamber and dust-separating appliance; Said accommodating chamber holds said motor and motor inner cover; Said flexible holder is arranged at the side of accommodating chamber near dust-separating appliance, and it specifically is that the said internal face of plate, top board, base plate, left plate and right panel and said accommodating chamber afterwards has the gap that the internal face of said back plate, top board, base plate, left plate and right panel and said casing has the gap.
As a kind of improvement project, the cross section of said flexible holder is arch.
As a kind of improvement project, said housing is the cavity structure with opening, and said opening is positioned at second end, the said said opening of flexible holder shutoff and be connected in said second end.
As a kind of improvement project; Said housing comprises rear wall and sidewall, and this rear wall is positioned at said first end, and this sidewall extends and cylindrical and surround said cavity with said rear wall around the circumference of rear wall; Said opening and said rear wall are arranged at sidewall over against, said support portion and near said rear wall.
Compared with prior art, the present invention has the following advantages:
1. because the support portion of motor inner cover of the present invention connects the supporting seat of casing, flexible holder is against casing and motor, and said motor inner cover only connects supporting seat by said flexible holder against said casing and support portion and is connected with casing; Like this; A strong point is only arranged, and flexible holder and casing be flexible the contact, so; Can significantly reduce the noise that vibrations and friction cause, noise is little.
Since said motor only by the front end of motor and said flexible holder against and the rear end of motor be connected and be connected with first end of said housing through snubber block with said motor inner cover; Like this; Noise can be between the housing of motor inner cover and motor outer surface bounce-back and being weakened, further reach the purpose that reduces noise.

Fig. 3 is the partial enlarged drawing of A part among Fig. 2.
The specific embodiment
By specifying technology contents of the present invention, structural feature, being reached purpose and effect, will combine embodiment and conjunction with figs. to specify below.
See also Fig. 1 to Fig. 3, dust catcher of the present invention comprises casing 1, comprises the motor inner cover and the motor 3 of housing 21 and flexible holder 22.Said casing 1 comprises accommodating chamber 11 and dust-separating appliance 12; Also be provided with supporting seat 13 and be positioned at the convex tendon 14 on the relative internal face; Concrete, said supporting seat 13 protrudes out and is positioned at accommodating chamber 11 to the top of accommodating chamber 11 from the bottom of accommodating chamber 11, offers groove on the supporting seat 13; Convex tendon 14 is arranged on the relative internal face of accommodating chamber 11.Said housing 21 has the first relative end and second end, such as, said first end is the left side of the drawing of Fig. 1 and Fig. 2, and second end is the right side of drawing, and first end of housing 21 is provided with said support portion 23.In the present embodiment; Said housing 21 is the cavity structures with opening 213, and said opening 213 is positioned at second end, such as; Said housing 21 comprises rear wall 211 and sidewall 212; This rear wall 211 is positioned at said first end, and this sidewall 212 extends and cylindrical and surround said cavity with said rear wall 211 around the circumference of rear wall 211, said opening 213 and said rear wall 211 over against.Offer groove on the said rear wall 211, be provided with said snubber block 24 in each groove.Said support portion 23 is arranged on the sidewall 212 and near said rear wall 211, in concrete embodiment, said support portion 23 protrudes out to the outside of housing 21 from said sidewall 212 and forms.Said flexible holder 22 is connected in second end of housing 21, processes by expanded material, such as; Polyurethane material also can be processed by elastomeric material, is used for damping; In the present embodiment, the cross section of said flexible holder 22 is arch, the said opening 213 of shutoff and be connected in said second end; Concrete, this flexibility holder 22 has contact site 221, the sidewall 212 of this contact site 221 and housing 21 against and the said opening 213 of shutoff.
Please continue to consult Fig. 1 and Fig. 2, when motor inner cover of the present invention was assembled in dust catcher, the rear end of said motor 3 was connected with said snubber block 24; The front end of motor 3 and said flexible holder 22 against; As shown in Figure 2, with said contact site 221 against, thus; Said motor 3 only by the front end of motor 3 and said flexible holder 22 against and the rear end of motor 3 be connected with first end of said housing 21 through snubber block 24 and be connected with said motor inner cover and surrounded by said motor inner cover; Like this, noise can be between the outer surface of the housing 21 of motor inner cover and motor 3 bounce-back and being weakened, can reduce noise.Said motor 3 is placed horizontally in the said motor inner cover, and is concrete, and with whole dust catcher as a reference, the rotating shaft of motor 3 is positioned at horizontal level.The support portion 23 of motor inner cover is connected with said supporting seat 13, such as, support portion 23 is stuck in the groove of supporting seat 13.Said convex tendon 14 is connected to the both sides of said flexible holder 22 respectively, such as, the width of flexible holder 22 makes said flexible holder 22 to establish with convex tendon 14 cards less times greater than the distance between two convex tendons 14.Said motor inner cover only 23 is connected said supporting seats 13 and is connected with described casing 1 against casing 1 and support portion by described flexible holder 22, thereby said accommodating chamber 11 holds said motor 3 and motor inner cover; Said flexible holder 22 is arranged at the side of accommodating chamber 11 near dust-separating appliance 12; Through such setting, the front portion of said motor inner cover is flexible the contact with casing 1, and only there is a strong point at the rear portion; Therefore, can significantly reduce the noise that vibrations and friction cause.
