Below with reference to Fig. 1-Fig. 4, the vibration absorber according to the dust catcher of the embodiment of the present invention is described.
As shown in Figure 1, according to the vibration absorber of the dust catcher of the embodiment of the present invention, comprising: motor cover 1, motor 2 and vibration-damped component 3, motor 2 is contained in motor cover 1, and vibration-damped component 3 is located in motor cover 1 by ledge structure 4 to weaken the vibration that motor 2 produces.Alternatively, vibration-damped component 3 is rubber member, and the scope of the hardness of rubber member is 45 ° ± 5 °.
Thus, when motor 2 runs, motor 2 itself can because motor 2 impeller (scheming not shown) rotates the centrifugal force produced produce vibration, this vibration outwards can be transmitted successively along the object around motor 2, when on vibration passing to motor cover 1, ledge structure between motor cover 1 and vibration-damped component 3, by vibration passing to vibration-damped component 3, and ledge structure 4 achieves the linear contact between motor cover 1 and vibration-damped component 3, contact compared to traditional face, greatly reduce this vibration, thus reach damping vibration and reduce the object resonated, and then reach the final object reducing noise.
According to the vibration absorber of the dust catcher of the embodiment of the present invention, by the ledge structure 4 between motor cover 1 and vibration-damped component 3, achieve the linear contact between motor cover 1 and vibration-damped component 3, thus reduce vibration and decrease resonance, and then reduce the noise of dust catcher.
According to some embodiments of the present invention, as depicted in figs. 1 and 2, vibration-damped component 3 is located between motor cover 1 and motor 2.Motor cover 1 can be one deck, also can be multilayer.Specifically, as shown in Figure 2, ledge structure 4 comprises: to be located on inner surface that first step portion 41a on one end (being such as the lower end in Fig. 1 and Fig. 2) of vibration-damped component 3 and second step portion 42a, second step portion 42a be located at motor cover 1 and to coordinate with first step portion 41a.The other end (being such as the upper end in Fig. 1 and Fig. 2) of vibration-damped component 3 is only against on motor 2.
Alternatively, ledge structure 4 is formed as the step shape being greater than three grades.That is, first step portion 41a has the multi-stage stairs being greater than 3 grades, as shown in Figure 2.Correspondingly, the second step portion 42a coordinated to first step portion 41a also has the step shape of corresponding progression.Wherein, the height of every grade of step can adjust according to specific design, contacts as long as can to ensure between motor cover 1 and vibration-damped component 3 linear.
In an alternate exemplary, ledge structure 4 around the circumferential hoop of vibration-damped component 3 around layout, as depicted in figs. 1 and 2.And in another alternate exemplary, ledge structure is that multiple and around vibration-damped component 3 axisymmetrical is arranged, such as ledge structure 4 is even number, is arranged in symmetrically respectively in the peripheral surface of vibration-damped component 3.
As shown in Figure 3 and Figure 4, according to other embodiments of the present invention, motor cover 1 comprises the first motor cover 11 and the second motor cover 12, wherein motor 2 is contained in the first motor cover 11, and the first motor cover 11 is set in the second motor cover 12, vibration-damped component 3 to be located between the first motor cover 11 and the second motor cover 12 and to be coordinated by ledge structure 4 with the first motor cover 11.
Wherein, above-mentioned " motor 2 is contained in the first motor cover 11 " mentioned is not limited to motor 2 and is directly contained in the first motor cover 11, alternatively, in example as shown in Figures 2 and 3, in the first motor cover 11, also there is interior motor cover 13, and motor 2 is directly accommodated in the inner in motor cover 13.Certainly, those skilled in the art are appreciated that interior motor cover 13 is also not limited to one deck, and in the unshowned alternate exemplary of some figure, interior motor cover 13 can comprise multilayer that is sheathed successively and that be communicated with.In addition, similarly, the second motor cover 12 may not be outermost motor cover, and the second motor cover 12 outside can also be arranged with the outer motor cover of one deck, or the inside and outside sheathed and outer motor cover of the multilayer be communicated with successively, schemes all not shown, is not described in detail at this.Outermost layer motor cover has the air that motor sucks is discharged to exhaust outlet 14 in follow-up gas extraction system (scheming not shown).In the following description, be all described for the example shown in Fig. 3, wherein the second motor cover 12 is outermost layer, therefore exhaust outlet 14 is the air outlet of the second motor cover.
As shown in Figure 4, the ledge structure 4 of the embodiment of the present invention comprises: be located at the first step portion 41b on one end (upper end as in Fig. 4) of vibration-damped component 3 and second step portion 42b, second step portion 42b to be located in one of them in the first motor cover 11 and the second motor cover 12 and to extend towards another, and second step portion 42b coordinates with first step portion 41b.Alternatively, second step portion 42b is located on the outer surface of the first motor cover 11.The inner surface of the second motor cover 12 is formed with installation portion 121, and the other end (lower end as in Fig. 4) of vibration-damped component 3 is located in installation portion 121.
Thus, when motor 2 runs, motor 2 itself can because motor 2 impeller (scheming not shown) rotates the centrifugal force produced produce vibration, this vibration outwards can be transmitted successively along the object around motor 2, when on vibration passing to the first motor cover 11, ledge structure between the first motor cover 11 and vibration-damped component 3, by vibration passing to vibration-damped component 3, and then passes to the second motor cover 12.Ledge structure 4 achieves the linear contact between motor cover 1 and vibration-damped component 3, compared to the contact of traditional face, greatly reduces this vibration, thus reaches damping vibration and reduce the object resonated, and then reach the final object reducing noise.In the process, entered in interior motor cover 13 by the air that motor 2 sucks, inwall along interior motor cover 13 flows, and to enter in the first motor cover 11 and inwall along the first motor cover 11 flows from interior air outlet 131, then enter in the second motor cover 12 from the first air outlet 111, be then discharged to from exhaust outlet 14 in the exhaust apparatus being connected to vibration absorber downstream.The vibration weakening that motor during motor rotation itself can be produced like this, prevents it from outwards transmitting, in order to avoid produce covibration, and then obtains better quiet or super-silent product.
Alternatively, ledge structure 4 is formed as the step shape being greater than three grades.That is, first step portion 41b has the multi-stage stairs being greater than 3 grades, as shown in Figure 4.Correspondingly, the second step portion 42b coordinated to first step portion 41b also has the step shape of corresponding progression.Wherein, the height of every grade of step can adjust according to specific design, contacts as long as can to ensure between motor cover 1 and vibration-damped component 3 linear.
In an alternate exemplary, ledge structure 4 around the circumferential hoop of vibration-damped component 3 around layout, as shown in Figure 3 and Figure 4.And in another alternate exemplary, ledge structure is that multiple and around vibration-damped component 3 axisymmetrical is arranged, such as ledge structure 4 is even number, is arranged in symmetrically respectively in the peripheral surface of vibration-damped component 3.
