正如图2至图4所示，来自电动机10背面噪声输出孔11的噪声，经过位于电动机后壳体中的电动机过滤器50，然后引入四边形输出孔71，在同电动机前壳体30连在一起，把电动机10装在内中的后壳体70上的内圆周上形成四边形输出孔71。噪声在用螺栓120配装在吸尘器主体110的空间111中的电动机外罩130中使之降低，然后流出吸尘器主体110的流出口112，如图3所示，电动机外罩130的内底部131中央有一个四边形的开孔132，用于把减弱的噪声排出外面，在四边形开孔132下面，形成有一个圆弧形，同开孔132相连通的输出管段133，使噪声可经过四边形开孔132传到电动机前壳体30。标号140和150各自表示一块丙烯板和一块无纺织物，用于形成一条通道。As shown in Figures 2 to 4, the noise from the noise output hole 11 on the back side of the motor 10 passes through the motor filter 50 positioned in the motor rear housing, then introduces the quadrilateral output hole 71, and is connected together with the motor front housing 30 A quadrilateral output hole 71 is formed on the inner circumference of the rear case 70 in which the motor 10 is housed. The noise is reduced in the motor housing 130 fitted in the space 111 of the vacuum cleaner main body 110 with bolts 120, and then flows out of the outlet 112 of the vacuum cleaner main body 110. As shown in Figure 3, there is a central part of the inner bottom 131 of the motor housing 130. The quadrangular opening 132 is used to discharge the weakened noise to the outside. Below the quadrangular opening 132, an arc shape is formed, which is connected with the output pipe section 133 of the opening 132, so that the noise can pass through the quadrangular opening 132 to Motor front housing 30 . Reference numerals 140 and 150 each denote an acrylic plate and a non-woven fabric for forming a channel.

按照本发明的噪声降低途径，从电动机底部噪声输出孔11输出的噪声，途径电动机过滤器50，再流经电动机后壳体70的四边形输出孔71。然后又经过四边形开孔132流出输出管段133，和通过由丙烯板140和非纺织物150构成的通道，排至吸尘器主体110的出口112。According to the noise reduction approach of the present invention, the noise output from the noise output hole 11 at the bottom of the motor passes through the motor filter 50 and then flows through the quadrilateral output hole 71 of the motor rear housing 70 . Then it flows out of the output pipe section 133 through the quadrangular opening 132 , and is discharged to the outlet 112 of the main body 110 of the vacuum cleaner through the channel formed by the acrylic plate 140 and the non-woven fabric 150 .

噪声的排放路途变得很长，因而噪声降低很多。The emission path of the noise becomes very long, so the noise is reduced a lot.

图5和图6示出本发明的第二个优选实施方案。在这一实施方案中，电动机外罩130在其侧壁上开有两个同电动机前壳体30紧密接触的圆孔134。这两个圆孔134彼此隔开一给定的距离。Figures 5 and 6 show a second preferred embodiment of the invention. In this embodiment, the motor housing 130 has two round holes 134 on its side wall which are in close contact with the motor front housing 30 . The two circular holes 134 are spaced apart from each other by a given distance.

按照第二个优选实施方案的噪声降低途径，来自电动机10的噪声输出孔11的噪声，途径电动机过滤器50，传至电动机后壳体70的四边形输出孔71。然后又通过电动机外罩130的圆孔134和通过由丙烯板140和非纺织物150构成的通道，排至吸尘器主体110的出口112。According to the noise reduction approach of the second preferred embodiment, the noise from the noise output hole 11 of the motor 10 passes through the motor filter 50 to the quadrangular output hole 71 of the motor rear housing 70 . Then it is discharged to the outlet 112 of the main body 110 of the vacuum cleaner through the circular hole 134 of the motor housing 130 and through the channel formed by the acrylic plate 140 and the non-woven fabric 150 .

从电动机后壳体70的四边形输出孔71输出的噪声，传至同前壳体30接触的电动机外罩130的圆孔134，由于噪声的排放途径变长了，因而导致噪声的降低。The noise output from the quadrangular output hole 71 of the motor rear housing 70 is passed to the circular hole 134 of the motor housing 130 in contact with the front housing 30, and the emission path of the noise becomes longer, thereby reducing the noise.

图7和图8示意地示出本发明的第三个优选实施方案的真空吸尘器电动机的噪声降低机构。第三个优选实施方案的电动机外罩130，在它同电动机前壳体30相接触，又同电动机密封件和相连接的下侧面开有一个半圆形出口135。7 and 8 schematically show a noise reduction mechanism for a vacuum cleaner motor according to a third preferred embodiment of the present invention. The motor housing 130 of the third preferred embodiment has a semicircular outlet 135 on the lower side where it is in contact with the motor front housing 30 and connected with the motor seal.

按照第三个优选实施方案的噪声降低途径，来自电动机10的噪声输出孔11的噪声，途径电动机过滤器50，传至电动机后壳体70的四边形输出孔71，然后又通过电动机外罩130的半圆形出口135。随后，噪声又经过由丙烯板140和非纺织物150构成的通道排放至吸尘器主体110的出口112。According to the noise reduction approach of the third preferred embodiment, the noise from the noise output hole 11 of the motor 10 passes through the motor filter 50 to the quadrilateral output hole 71 of the motor rear housing 70, and then passes through the half of the motor housing 130. Circular exit 135. Then, the noise is discharged to the outlet 112 of the cleaner main body 110 through the passage formed by the acrylic plate 140 and the non-woven fabric 150 .

从电动机后壳体70的四边形输出孔71输出的噪声，输经同电动机前壳体30接触的电动机外罩130的半圆形出口135，因此，形成的通道是同第二个优选实施方案的通道相似。The noise output from the quadrangular output hole 71 of the motor rear housing 70 is transmitted through the semicircular outlet 135 of the motor housing 130 in contact with the motor front housing 30, therefore, the passage that is formed is the same as the passage of the second preferred embodiment resemblance.

图9和图10示出了本发明的第四个优选实施方案。电动机外罩130沿其圆周有两条翻边136，同电动机后壳体70的后侧73和前侧做成的一个凹槽72相接触，这两条翻边136使电动机外罩130同电动机后壳体70的外圆周形成一个空间137，并由切开翻边136和空间137的一个预定部分形成一个排出口138。9 and 10 show a fourth preferred embodiment of the present invention. The motor cover 130 has two flanges 136 along its circumference, which are in contact with a groove 72 made on the rear side 73 and the front side of the motor rear housing 70. These two flanges 136 make the motor housing 130 and the motor rear housing A space 137 is formed on the outer circumference of the body 70, and a discharge port 138 is formed by cutting out the flange 136 and a predetermined portion of the space 137. As shown in FIG.

在第四个优选实施方案中的噪声降低机构中，从电动机10的噪声输出孔11输出的噪声，途经电动机过滤器50，流过电动机后壳体70的四边形输出孔71，然后转向180度，沿电动机外罩130的空间137，流出排出口138，再流经由丙烯板140和非纺织物150构成的通道，送出吸尘器主体110的出口112。In the noise reduction mechanism in the fourth preferred embodiment, the noise output from the noise output hole 11 of the motor 10 passes through the motor filter 50, flows through the quadrilateral output hole 71 of the motor rear housing 70, and then turns 180 degrees, Along the space 137 of the motor housing 130 , it flows out of the discharge port 138 , and then flows through the channel formed by the acrylic plate 140 and the non-woven fabric 150 , and is sent out to the outlet 112 of the cleaner main body 110 .

如上所述，由电动机运行时产生的噪声的排放途径，通过改变电动机外罩130的形状可有多种的变化途径，使之通道变长，因而真空吸尘器操作时从外部听到的噪声就可大大地降低了。As mentioned above, the discharge path of the noise generated when the motor is running can be changed in many ways by changing the shape of the motor housing 130, so that the passage becomes longer, so that the noise heard from the outside during the operation of the vacuum cleaner can be greatly improved. lowered.
