The terms used herein in the description of the present invention are for the purpose of describing specific embodiments only, and are not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

如图1-3所示，本发明一实施例中，提供一种吸尘装置100，包括外壳10、电源16及均设于外壳10内的气流发生器30和第一气尘分离件50。As shown in FIGS. 1-3 , in an embodiment of the present invention, adust suction device 100 is provided, which includes ahousing 10 , a power source 16 , anairflow generator 30 and a first air-dust separatingmember 50 both disposed in thehousing 10 .

电源16用于向气流发生器30供电，气流发生器30提供带动外界气流流入吸尘器的气流吸力，第一气尘分离件50具有位于气流发生器30上游的第一气尘分离腔52。气流发生器30工作时产生的气流吸力，带动外界气流进入第一气尘分离腔52进行气尘分离，完成灰尘分离的干净空气从第一气尘分离腔52流出后经过气流发生器30排向外界，如此完成吸尘工作。The power source 16 is used to supply power to theairflow generator 30 . Theairflow generator 30 provides airflow suction to drive the external airflow into the vacuum cleaner. The airflow suction generated when theairflow generator 30 is working drives the external airflow into the first air-dust separation chamber 52 for air-dust separation. Outside, vacuuming is done in this way.

如图2及图7所示，一些实施例中，第一气尘分离件50围绕气流发生器30的外周设置，且第一气尘分离件50内部形成有第一气尘分离腔52。这样，第一气尘分离腔52围绕于气流发生器30外周，可以通过第一气尘分离腔52吸收气流发生器30工作时产生的噪音，降低吸尘装置100的噪音。并且，第一气尘分离件50与气流发生器30之间形成有位于气流发生器30下游并与气流发生器30连通的排气通道60，从第一气尘分离腔52流出的干净空气经过气流发生器30后进入排气通道60，从排气通道60排向外界。同时，气流发生器30与第一气尘分离件50之间围设形成排气通道60，相当于排气通道60位于气流发生器30外周，可进一步吸收气流发生器30工作时产生的噪音，进一步降低吸尘装置100的噪音，提高静音性，方便用户使用吸尘器。As shown in FIGS. 2 and 7 , in some embodiments, the first air-dust separation member 50 is disposed around the outer periphery of theairflow generator 30 , and a first air-dust separation chamber 52 is formed inside the first air-dust separation member 50 . In this way, the first air-dust separation cavity 52 surrounds the outer periphery of theairflow generator 30 , and the noise generated by the air-flow generator 30 can be absorbed through the first air-dust separation cavity 52 to reduce the noise of thedust collecting device 100 . In addition, anexhaust channel 60 located downstream of theairflow generator 30 and communicated with theairflow generator 30 is formed between the first air-dust separatingmember 50 and theairflow generator 30, and the clean air flowing out from the first air-dust separating chamber 52 passes through Theairflow generator 30 then enters theexhaust passage 60 and is discharged from theexhaust passage 60 to the outside. At the same time, anexhaust channel 60 is formed between theairflow generator 30 and the first air-dust separation member 50, which is equivalent to theexhaust channel 60 being located on the outer periphery of theairflow generator 30, which can further absorb the noise generated by theairflow generator 30 when it is working. The noise of thevacuum cleaner 100 is further reduced, the quietness is improved, and it is convenient for the user to use the vacuum cleaner.

如图4-5所示，具体地，第一气尘分离件50包括多个第一子气尘分离件51，第一气尘分离腔52包括多个形成于每个第一子气尘分离件51内的第一子气尘分离腔521。多个第一子气尘分离件51围绕气流发生器30的外周呈环形排布连接，每个第一子气尘分离件51内的第一子气尘分离腔521对流入的气流进行气尘分离，通过多个第一子气尘分离腔521高效地进行气尘分离。同时，通过多个围绕于气流发生器30外周的第一子气尘分离腔521吸收气流发生器30产生的噪音。As shown in FIGS. 4-5 , specifically, the first gas-dust separation member 50 includes a plurality of first sub-gas-dust separation members 51 , and the first gas-dust separation chamber 52 includes a plurality of first gas-dust separation members formed in each of the first sub-gas-dust separation members 51 . The first sub-gas-dust separation chamber 521 in thecomponent 51. A plurality of first sub-gas anddust separation members 51 are arranged and connected in a ring shape around the outer periphery of theairflow generator 30, and the first sub-gas anddust separation chamber 521 in each first sub-gas anddust separation member 51 performs gas-dust separation on the inflowing airflow. The gas and dust are efficiently separated through the plurality of first sub-gas-dust separation chambers 521 . At the same time, the noise generated by theairflow generator 30 is absorbed through a plurality of first sub-gas-dust separation chambers 521 surrounding the outer periphery of theairflow generator 30 .

可选地，每个第一子气尘分离件51为旋风分离器，当带有灰尘和赃物的气流进入旋风分离器后螺旋向下转动，而灰尘和赃物在转动过程中因为质量较大可以获得较大的离心力，最后撞击到旋风分离器的内壁后在自身重力作用下掉入集尘腔，同时干净的空气由旋风分离器排出，如此实现气尘分离。Optionally, each first sub-air-dust separation part 51 is a cyclone separator. When the airflow with dust and dirt enters the cyclone separator, it rotates downward, and the dust and dirt can be rotated during the rotation process because of their large mass. A large centrifugal force is obtained, and finally it hits the inner wall of the cyclone and falls into the dust collection chamber under the action of its own gravity. At the same time, the clean air is discharged from the cyclone, thus realizing the separation of gas and dust.

如图2-3所示，一些实施例中，吸尘装置100还包括具有第二气尘分离腔41的第二气尘分离件40，第二气尘分离件40上开设有与第二气尘分离腔41连通的进气口43，且第二气尘分离腔41位于第一气尘分离腔52上游并与第一气尘分离腔52连通。也就是说，在第一气尘分离件50之前还设置有第二气尘分离件40，气流发生器30产生的气流吸力，带动气流先由进气口43进入第二气尘分离件40进行一次气尘分离，然后再进入第一气尘分离件50再进行次气尘分离，如此实现对空气二次气尘分离，气尘分离率更高，分离效果更好。As shown in FIGS. 2-3 , in some embodiments, thedust collector 100 further includes a second air-dust separation member 40 having a second air-dust separation chamber 41 , and the second air-dust separation member 40 is provided with a second air-dust separation member 40 . Thedust separation chamber 41 communicates with theair inlet 43 , and the second gas anddust separation chamber 41 is located upstream of the first gas anddust separation chamber 52 and communicates with the first gas anddust separation chamber 52 . That is to say, a second air-dust separation member 40 is also provided before the first air-dust separation member 50, and the air suction force generated by theairflow generator 30 drives the air flow to enter the second air-dust separation member 40 through theair inlet 43 first. The primary gas and dust are separated, and then enter the first gas anddust separation member 50 for secondary gas and dust separation, thus realizing the secondary gas and dust separation of the air, the gas and dust separation rate is higher, and the separation effect is better.

进一步地，外壳10与第一气尘分离件50之间形成有进气通道12，进气通道12连通于第一气尘分离腔52和第二气尘分离腔41之间，第二气尘分离腔41内的气流通过进气通道12进入第一气尘分离腔52。并且，第一气尘分离件50围绕气流发生器30的外周设置，而位于第一气尘分离件50与外壳10之间的进气通道12，也会围绕于第一气尘分离件50外，进而位于气流发生器30外周，如此还可通过进气通道12吸收气流发生器30产生的噪音。Further, anair intake channel 12 is formed between thehousing 10 and the first air anddust separation member 50 , and theair intake channel 12 is communicated between the first air anddust separation chamber 52 and the second air anddust separation chamber 41 . The air flow in theseparation chamber 41 enters the first gas anddust separation chamber 52 through theair intake passage 12 . In addition, the first air-dust separation member 50 is disposed around the outer circumference of theairflow generator 30 , and theair intake passage 12 located between the first air-dust separation member 50 and thehousing 10 also surrounds the outside of the first air-dust separation member 50 . , and then located on the outer periphery of theairflow generator 30 , so that the noise generated by theairflow generator 30 can also be absorbed through theair intake passage 12 .

具体地，气流发生器30外依次围设有位于气流发生器30与第一气尘分离件50之间的排气通道60、位于第一气尘分离件50内的第一气尘分离腔52、及位于第一气尘分离件50与外壳10之间的进气通道12，即排气通道60、第一气尘分离腔52及进气通道12由内向外依次排布在气流发生器30外周，对气流发生器30产生的噪音进行多层吸收，有效降低吸尘装置100工作时传递出的噪音，提高用户的使用体验。Specifically, theairflow generator 30 is provided with anexhaust passage 60 located between theairflow generator 30 and thefirst dust separator 50 and a firstdust separator cavity 52 located in thefirst dust separator 50 in sequence. , and theair intake channel 12 between the first air-dust separation member 50 and thehousing 10, namely theexhaust air channel 60, the first air-dust separation chamber 52 and theair intake channel 12 are sequentially arranged in theairflow generator 30 from the inside to the outside. At the outer periphery, the noise generated by theairflow generator 30 is absorbed in multiple layers, which effectively reduces the noise transmitted by thevacuum cleaner 100 during operation and improves the user experience.

一些实施例中，吸尘装置100还包括引流件70，引流件70设于外壳10内。并且，第一气尘分离件50的排气口与气流发生器30的吸气口位于外壳10内的同一端，引流件70设于气流发生器30的吸气侧且具有连通第一气尘分离件50的排气口与气流发生器30的吸气口的引流通道72，第一气尘分离件50中排出的干净空气通过引流通道72流向气流发生器30。同时，第一气尘分离件50的排气口位于气流发生器30的吸气侧，引流通道72只需在气流发生器30的吸气端设置，便可连通第一气尘分离件的排气口与气流发生器30的吸气口，引流通道72较短，气流的流动阻力较小，加速气流流速，提高吸气流量。In some embodiments, thedust suction device 100 further includes adrainage member 70 , and thedrainage member 70 is disposed in thehousing 10 . In addition, the exhaust port of the first air-dust separation member 50 and the suction port of theairflow generator 30 are located at the same end in thecasing 10, and thedrainage member 70 is arranged on the suction side of theairflow generator 30 and has a connection with the first air-dust. The exhaust port of theseparation member 50 and thedrainage channel 72 of the suction port of theairflow generator 30, the clean air discharged from the first air-dust separation member 50 flows to theairflow generator 30 through thedrainage channel 72. At the same time, the exhaust port of the first air-dust separation member 50 is located on the suction side of theairflow generator 30, and thedrainage channel 72 only needs to be provided at the suction end of theairflow generator 30 to communicate with the exhaust port of the first air-dust separation member. The air port and the suction port of theairflow generator 30, thedrainage channel 72 is shorter, the flow resistance of the airflow is smaller, the airflow velocity is accelerated, and the suction flow rate is increased.

具体地，气流发生器30包括电机和连接于电机输出端的风叶，电机工作时带动风叶旋转，进而形成带动气流进入吸尘装置100的气流吸力。其中，气流发生器30具有风叶的一端为吸气端，将气流发生器30具有风叶的一端设置为与第一气尘分离件50的排气端位于同一侧，如此便可将气流发生器30的吸气端与第一气尘分离件50的排气端设置于同一侧，减小气流在第一气尘分离件50与气流发生器30之间流动的阻力。Specifically, theairflow generator 30 includes a motor and a fan blade connected to the output end of the motor. The motor drives the fan blade to rotate during operation, thereby forming an airflow suction force that drives the airflow into thedust collector 100 . Wherein, the end of theairflow generator 30 with the fan blades is the suction end, and the end of theairflow generator 30 with the fan blades is located on the same side as the exhaust end of the first air-dust separation member 50, so that the airflow can be generated. The suction end of thedevice 30 and the exhaust end of the first air-dust separation member 50 are arranged on the same side, so as to reduce the resistance of the airflow flowing between the first air-dust separation member 50 and theairflow generator 30 .

更具体地，吸尘装置100还包括前置过滤器32，前置过滤器32套设于气流发生器30的吸器端，即前置过滤器32套设于气流发生器30具有风叶的一端，且前置过滤器32与引流通道72连通，以过滤由引流通道72流向气流发生器30内的气流，防止气流发生器30内部积聚灰尘。而且，壳体10上开设有与气流发生器30的吸气端对应的安装口15，前置过滤器32可拆卸地装配于安装口15内，在需要清洗前置过滤器32时，可从壳体10的安装口15处方便地拆卸前置过滤器32。More specifically, thedust collector 100 further includes a pre-filter 32, and the pre-filter 32 is sleeved on the suction end of theairflow generator 30, that is, the pre-filter 32 is sleeved on the end of theairflow generator 30 with a fan blade. , and the pre-filter 32 communicates with thedrainage channel 72 to filter the airflow flowing into theairflow generator 30 from thedrainage channel 72 to prevent dust from accumulating inside theairflow generator 30 . Moreover, thehousing 10 is provided with aninstallation port 15 corresponding to the suction end of theairflow generator 30, and the pre-filter 32 is detachably assembled in theinstallation port 15. When the pre-filter 32 needs to be cleaned, it can be removed from the The pre-filter 32 is easily disassembled at theinstallation port 15 of thehousing 10 .

进一步地，引流件70与外壳10之间围设形成有与排气通道60的出口连通的引流腔74，外壳10上开设有与引流腔74连通的排气孔14。将引流件70设于气流发生器30的吸气侧后，引流件70外壁与外壳10内壁之间还围设形成与排气通道60的出口连通的引流腔74，通过引流腔74将排气通道60中的干净空气通过排气孔14排向外部。如此，引流件70不仅自身内部形成引流通道72，引流件70还与外壳10之间界定形成引流腔74，实现多重功能。Further, adrainage cavity 74 that communicates with the outlet of theexhaust passage 60 is formed between thedrainage member 70 and thecasing 10 , and thecasing 10 is provided with anexhaust hole 14 that communicates with thedrainage cavity 74 . After thedrainage member 70 is arranged on the suction side of theairflow generator 30, adrainage cavity 74 is also formed between the outer wall of thedrainage member 70 and the inner wall of thehousing 10, which is communicated with the outlet of theexhaust passage 60, and the exhaust is discharged through thedrainage cavity 74.
