The first air passage 271 and the second air passage 272 constitute the air passage 270.
可选地， 第三电机罩 240包括一层罩体， 如图 2和图 5所示。 优选地， 第三电机罩 240与第二电机罩 230之间的距离范围在 5mm_40mm之间。 当然， 本发明并不限于此， 在本发明的另一些可选实施例中， 第三电机罩 240包括从内到外依次套设的多层罩体， 如图 3所示的示例中， 第三电机罩 240包括第一子罩体 241和第二子罩体 242， 此时， 在第一子罩体 241和第二子罩体 242之间还可以限定出第三风道 273， 与上述实施例中 类似， 第三风道 273可以与第二风道 272连通， 而出风口设在第二子罩体 242上以便将 第三风道 273内流动的气体排出。优选地， 第三电机罩 240中每层罩体之间的距离范围 在 5mm-40mm之间。  Optionally, the third motor cover 240 includes a layer of cover, as shown in Figures 2 and 5. Preferably, the distance between the third motor cover 240 and the second motor cover 230 ranges between 5 mm and 40 mm. Of course, the present invention is not limited thereto. In other optional embodiments of the present invention, the third motor cover 240 includes a multi-layer cover that is sequentially disposed from the inside to the outside, as in the example shown in FIG. The third motor cover 240 includes a first sub-cover 241 and a second sub-cover 242. At this time, a third air passage 273 may be defined between the first sub-cover 241 and the second sub-cover 242, and the above Similarly in the embodiment, the third air passage 273 may be in communication with the second air passage 272, and the air outlet is provided on the second sub-cover 242 to discharge the gas flowing in the third air passage 273. Preferably, the distance between each layer of the third motor cover 240 ranges from 5 mm to 40 mm.
为了描述简便， 在下面的说明中， 均以第三电机罩 240为一层进行描述。 本领域内 普通技术人员可以理解，当第三电机罩 240包括从内到外依次套设的二层及二层以上罩 体时， 其内部空气的流动与一层罩体时空气的流动方式类似， 在此不再详细列举。  For the sake of simplicity of description, in the following description, the third motor cover 240 is described as a layer. It will be understood by those skilled in the art that when the third motor cover 240 includes two or more layers of casings which are sequentially arranged from the inside to the outside, the flow of the internal air is similar to the flow of air in the case of a cover. , will not be listed in detail here.
排气装置 300设在第三电机罩 240后且包括排气罩 310， 排气罩 310与第三电机罩 240限定出排气通道 320， 排气通道 320通过出风口 260与风道 270连通且通过排气口 350与吸尘器的外部环境连通。  The exhaust device 300 is disposed behind the third motor cover 240 and includes an exhaust cover 310. The exhaust cover 310 and the third motor cover 240 define an exhaust passage 320 that communicates with the air passage 270 through the air outlet 260 and It communicates with the external environment of the cleaner through the exhaust port 350.
由此， 电机 210转动在第一电机罩 220内产生负压， 带有灰尘的空气被紊乱地吸入 集尘装置 100内， 在进气口 250处灰尘被过滤， 空气进入第一电机罩 220内。 此时， 被 电机 210吸入的紊乱气体沿着第一电机罩 220、第二电机罩 230和第三电机罩 240内共 同限定出的风道 270流动， 而且由于该风道 270足够长， 因此可以给紊乱的气流提供足 够的空间而稳定下来， 从而降低了空气的流动。 而且， 由于第一至第三电机罩之间由于 气体的运动而形成了相对的真空， 这样， 可以大大降低了空气气流和电机 210本身运转 时产生的噪音和振动， 进而达到了足够的低噪音或超静音。 然后， 气体从第三电机罩 240的出风口排出， 并通过排气通道 320后排出到大气中。 Thereby, the motor 210 rotates to generate a negative pressure in the first motor cover 220, and the dusty air is inhaled in a disorderly manner. In the dust collecting device 100, dust is filtered at the air inlet 250, and air enters the first motor cover 220. At this time, the turbulent gas sucked by the motor 210 flows along the air passage 270 defined in the first motor cover 220, the second motor cover 230, and the third motor cover 240, and since the air passage 270 is long enough, Provides sufficient space for the turbulent airflow to stabilize, thereby reducing the flow of air. Moreover, since the relative vacuum is formed between the first to third motor covers due to the movement of the gas, the air flow and the noise and vibration generated by the operation of the motor 210 itself can be greatly reduced, thereby achieving a sufficiently low noise. Or ultra-quiet. Then, the gas is discharged from the air outlet of the third motor cover 240, and is exhausted to the atmosphere through the exhaust passage 320.
根据本发明实施例的吸尘器， 由于足够延长了空气流动的风道长度， 从而稳定了气 流流动， 而且大大降低了噪音。 另外， 根据本发明的吸尘器， 结构简单成本低。  The vacuum cleaner according to the embodiment of the present invention stabilizes the flow of the air flow by sufficiently lengthening the length of the air passage through which the air flows, and greatly reduces the noise. Further, the vacuum cleaner according to the present invention is simple in structure and low in cost.
如图 2所示， 根据本发明的一个实施例， 第一电机罩 220的周壁上形成有第一出气 口 221， 第二电机罩 230套设在第一电机罩 220的外部， 第二电机罩 230的周壁上形成 有第二出气口 231， 第二电机罩 230与第一电机罩 220之间限定出通过第一出气口 221 与第一电机罩 220内部连通的第一风道 271。第三电机罩 240套设在第二电机罩 230的 外部且与第二电机罩 230之间限定出通过第二出气口 231与第一风道 271连通的第二风 道 272， 其中第一风道 271和第二风道 272构成风道 270。  As shown in FIG. 2, according to an embodiment of the present invention, a first air outlet 221 is formed on a peripheral wall of the first motor cover 220, and the second motor cover 230 is sleeved outside the first motor cover 220, and the second motor cover is disposed. A second air outlet 231 is formed on the peripheral wall of the second motor cover 230, and a first air passage 271 that communicates with the inside of the first motor cover 220 through the first air outlet 221 is defined between the second motor cover 230 and the first motor cover 220. The third motor cover 240 is sleeved on the outside of the second motor cover 230 and defines a second air passage 272 that communicates with the first air passage 271 through the second air outlet 231, wherein the first wind is Lane 271 and second duct 272 form a duct 270.
由此， 如图 2中箭头所示， 气流从进气口 250处被电机 210吸入， 流入第一电机罩 220内，沿着第一电机罩 220的内壁流动，并从第一出气口 221到第一风道 271内流动， 然后从第二电机罩 230的第二出气口 230流出进入到第二风道 272内，沿着第三电机罩 240的内壁流动到出风口 260， 并流出到后面的排气罩 310中。 这样， 通过第一至第三 电机罩 220、 220、 230之间限定出的第一风道 271和第二风道 272， 实现了气流的迷宫 式流动， 延长了空气流动的风道长度， 使电机产生的噪音要通过长且曲折的风道才能传 到外界， 在风道中声音被大大减弱， 从而大大降低了噪音。  Thus, as indicated by the arrow in FIG. 2, the airflow is drawn in from the air inlet 250 by the motor 210, flows into the first motor cover 220, flows along the inner wall of the first motor cover 220, and passes from the first air outlet 221 to The first air passage 271 flows, then flows out from the second air outlet 230 of the second motor cover 230 into the second air passage 272, flows along the inner wall of the third motor cover 240 to the air outlet 260, and flows out to the rear. In the exhaust hood 310. Thus, the first air passage 271 and the second air passage 272 defined between the first to third motor covers 220, 220, 230 realize a labyrinth flow of the airflow, prolonging the air passage length of the air flow. The noise generated by the motor is transmitted to the outside through a long and tortuous air duct, and the sound is greatly reduced in the air passage, thereby greatly reducing the noise.
可选地， 第一出气口 221包括多个第一出气孔 2211， 如图 2和图 5所示， 多个第一 出气孔 2211在第一电机罩 220的部分周壁上沿轴向和周向均匀分布。 进一步地， 第二 出气口 231包括多个第二出气孔 2311， 多个第二出气孔 2311在第二电机罩 230的部分 周壁上沿轴向和周向均匀分布。优选地， 第二出气口 231与第一出气口 221在径向方向 上相对远离设置。 当然， 第一出气口 221和第二出气口 231还可以分别均为一个开口。  Optionally, the first air outlet 221 includes a plurality of first air outlets 2211. As shown in FIG. 2 and FIG. 5, the plurality of first air outlets 2211 are axially and circumferentially on a part of the peripheral wall of the first motor cover 220. Evenly distributed. Further, the second air outlet 231 includes a plurality of second air outlets 2311, and the plurality of second air outlets 2311 are evenly distributed in the axial direction and the circumferential direction on a part of the peripheral wall of the second motor cover 230. Preferably, the second air outlet 231 and the first air outlet 221 are disposed relatively far apart in the radial direction. Of course, the first air outlet 221 and the second air outlet 231 may each be an opening.
在本发明一个具体的优选实施例中， 多个第一出气孔分布在第一电机罩 220的一半 周壁上， 多个第二出气孔分布在第二电机罩 230的另一半周壁上， 如图 2和图 5所示。 由此， 风道足够延长， 从而使得气流可以有尽可能大的空间稳定下来， 并减小噪音。  In a specific preferred embodiment of the present invention, the plurality of first air outlets are distributed on one half of the peripheral wall of the first motor cover 220, and the plurality of second air outlets are distributed on the other half of the second motor cover 230, as shown in the figure. 2 and Figure 5 are shown. Thereby, the air duct is sufficiently extended, so that the air flow can be stabilized as much as possible and the noise is reduced.
根据本发明的一些实施例， 如图 1和图 4所示， 在从出风口 260到远离出风口 260 的方向上、 排气通道 320的横截面积逐渐变大。 由此， 从出风口 260排出的空气， 在排 气通道 320内流动时， 由于排气通道 320的横截面积逐渐变大， 可以改变空气气流的流 速或频率， 从而大大地降低了空气气流本身产生的噪音和振动， 进而使得吸尘器的静音 效果更加明显。 其中， 本领域内普通技术人员可以理解， 排气罩 310的外形可以根据具 体产品的外形来设计， 只要能使排气通道 320的横截面积逐渐增大即可。 According to some embodiments of the present invention, as shown in FIGS. 1 and 4, the cross-sectional area of the exhaust passage 320 gradually increases in a direction from the air outlet 260 to away from the air outlet 260. Thereby, the air discharged from the air outlet 260 is in the row When flowing in the gas passage 320, since the cross-sectional area of the exhaust passage 320 is gradually increased, the flow rate or frequency of the air flow can be changed, thereby greatly reducing the noise and vibration generated by the air flow itself, thereby further improving the mute effect of the vacuum cleaner. obvious. It can be understood by those skilled in the art that the outer shape of the exhaust hood 310 can be designed according to the shape of the specific product as long as the cross-sectional area of the exhaust passage 320 can be gradually increased.
在其中一些优选实施例中， 排气装置 300还包括排气网板 330， 如图 4所示， 排气 网板 330设在第三电机罩 240的出风口 260上，且排气网板 330具有多个排气网孔 331。 由此， 通过设在出风口 260上的排气网板 330， 作为排气装置的第一层排气结构， 用于 降低从进气装置 200中排气气体的流速， 将其分流， 并改变其频率。 然而经过排气通道 320后， 进一步对气体流速进行降速， 并进一步改变其频率。  In some preferred embodiments, the exhaust device 300 further includes an exhaust stencil 330. As shown in FIG. 4, the exhaust stencil 330 is disposed on the air outlet 260 of the third motor cover 240, and the exhaust stencil 330 There are a plurality of exhaust mesh holes 331. Thus, the exhaust layer stencil 330 provided on the air outlet 260 serves as a first layer exhaust structure of the exhaust device for reducing the flow rate of the exhaust gas from the intake device 200, diverting it, and changing Its frequency. However, after passing through the exhaust passage 320, the gas flow rate is further reduced and the frequency is further changed.
可选地， 排气网孔 331的截面形状为圆形、 多边形、椭圆形或其他形状。进一步地， 在排气网板 330的排气气流方向上， 排气网孔 331的截面逐渐增大， 图未示出。  Alternatively, the cross-sectional shape of the exhaust mesh 331 is circular, polygonal, elliptical or other shape. Further, in the direction of the exhaust gas flow of the exhaust screen 330, the cross section of the exhaust mesh 331 gradually increases, not shown.

In an alternative example, a plurality of exhaust mesh openings 331 are evenly arranged in rows and columns on the exhaust stencil 330. In another alternative example, a plurality of exhaust mesh openings 331 are evenly spaced on the exhaust stencil 330 in a radially spaced annular shape.
如图 1和图 4所示， 在本发明的一些实施例中， 排气口 350处设置有过滤件 340， 即排气通道 320的远离出风口 260的一端处设置有过滤件 340。 可选地， 过滤件 340为 HEPA滤网。 由此， 从排气通道 320中排出的气体从 HEPA滤网流出，流回到大气环境中。 优选地， 在空气的流动方向上、邻近排气口 350的排气通道 320内可以设置多个依次并 排的过滤件 340 (图未示出） 。  As shown in Figures 1 and 4, in some embodiments of the present invention, a filter member 340 is disposed at the exhaust port 350, i.e., a filter member 340 is disposed at an end of the exhaust passage 320 remote from the air outlet 260. Optionally, filter element 340 is a HEPA filter. Thereby, the gas discharged from the exhaust passage 320 flows out of the HEPA filter and flows back to the atmosphere. Preferably, a plurality of sequentially arranged filter members 340 (not shown) may be disposed in the exhaust passage 320 adjacent to the exhaust port 350 in the flow direction of the air.
下面再参考图 1-图 5对根据本发明实施例的吸尘器的工作过程进行具体描述， 其中 以第三电机罩 240包括一层罩体为例进行说明。  The operation of the vacuum cleaner according to the embodiment of the present invention will be specifically described below with reference to Figs. 1 to 5, wherein the third motor cover 240 includes a cover body as an example for description.

如图 1和图 2中箭头所示， 气流从进气口 250处被电机 210吸入， 流入第一电机罩 220内，沿着第一电机罩 220的内壁流动，并从第一出气口 221到第一风道 271内流动， 然后从第二电机罩 230的第二出气口 230流出进入到第二风道 272内，沿着第三电机罩 240的内壁流动到出风口 260。  As shown by the arrows in FIGS. 1 and 2, the airflow is sucked from the air inlet 250 by the motor 210, flows into the first motor cover 220, flows along the inner wall of the first motor cover 220, and passes from the first air outlet 221 to The first air passage 271 flows and then flows out of the second air outlet 230 of the second motor cover 230 into the second air passage 272, and flows along the inner wall of the third motor cover 240 to the air outlet 260.
此时， 空气气流从设在出风口 260上的排气网板 330排出， 排气网板 330上具有多 个排气网孔 331， 从而降低了从进气装置 200中排气气体的流速， 将其分流， 并改变其 频率。 然后， 经过排气网板 330的气体在排气通道 320内流动， 由于排气通道 320的横 截面积逐渐变大， 进一步改变了空气气流的流速或频率， 从而大大地降低了空气气流本 身产生的噪音和振动， 进而使得吸尘器的静音效果更加明显。 根据本发明实施例的吸尘器中集成装置的具体构成以及进气、排气装置的其他构成以及 操作对于本领域普通技术人员而言都是已知的， 这里不再详细描述。 At this time, the air flow is exhausted from the exhaust mesh plate 330 provided on the air outlet 260, and the exhaust mesh plate 330 has a plurality of exhaust mesh holes 331, thereby reducing the flow rate of the exhaust gas from the intake device 200. Divert it and change its frequency. Then, the gas passing through the exhaust grid 330 flows in the exhaust passage 320, and the cross-sectional area of the exhaust passage 320 gradually becomes larger, further changing the flow rate or frequency of the air flow, thereby greatly reducing the air flow itself. The noise and vibration make the vacuum cleaner's mute effect more obvious. The specific configuration of the integrated device in the cleaner according to the embodiment of the present invention and other configurations and operations of the intake and exhaust devices are known to those skilled in the art and will not be described in detail herein.
