Vacuum cleaners generally use a motor to rotate at a high speed to generate air negative pressure in the sealed casing to absorb dust. Portable vacuum cleaners are a type of vacuum cleaner that is popular with users because of its light weight and compactness, especially in applications where space is small.
请参考图 1 , 图 1为现有技术中一种典型吸尘器收集装置的结构示意 图, 图中箭头所示方向为吸尘器工作时尘屑的运动方向。  Please refer to FIG. 1.

但是, 随着尘屑的增多, 收集到集尘室 12里的尘屑容易受动力电机的 影响, 产生向过滤器 11移动的趋势, 使尘屑粘附在过滤器 11上, 阻塞过 滤器 11的滤网。 这样不仅会增加动力电机的电耗, 增大吸尘器的噪音, 降 低除尘效率; 而且会影响过滤器 11的使用寿命, 增加过滤器 11的维护频 次, 并增加清洁成本。  However, as the amount of dust increases, the dust collected in the dust collecting chamber 12 is easily affected by the power motor, and tends to move toward the filter 11, so that the dust adheres to the filter 11, and the filter 11 is blocked. Filter. This not only increases the power consumption of the power motor, increases the noise of the vacuum cleaner, and reduces the dust removal efficiency; it also affects the service life of the filter 11, increases the frequency of maintenance of the filter 11, and increases the cleaning cost.
请参考图 2和图 3, 图 2为现有技术中一种收集装置的结构示意图; 图 3为图 2所示收集装置的工作状态示意图; 其中实线箭头所示方向为动 力部件形成的动力方向, 虚线箭头所示方向为尘屑的运动方向。  2 and FIG. 3, FIG. 2 is a schematic structural view of a collecting device in the prior art; FIG. 3 is a schematic view showing the working state of the collecting device shown in FIG. 2; wherein the direction indicated by the solid arrow is the power formed by the power component Direction, the direction indicated by the dotted arrow is the direction of movement of the dust.
专利号为 ZL201020289589.9的专利申请中, 发明人将进入集尘室 12 的风道改造为螺旋风道, 使尘屑进入集尘室 12后, 在过滤器 11的外周形 成如图 3所示的螺旋风,从而使尘屑尽可能远在送至集尘室 12的端部,远 离过滤器 11 , 以延长过滤器 11 的使用寿命, 降低吸尘器的噪音和电耗, 降低吸尘的成本。 In the patent application with the patent number ZL201020289589.9, the inventor transforms the air duct entering the dust collecting chamber 12 into a spiral air passage, so that the dust enters the dust collecting chamber 12, and is in the outer circumference of the filter 11. The spiral wind is as shown in FIG. 3, so that the dust is sent as far as possible to the end of the dust collecting chamber 12, away from the filter 11, to extend the service life of the filter 11, and reduce the noise and power consumption of the vacuum cleaner. Reduce the cost of vacuuming.
但是, 在一些尘屑较多的场合, 图 2和图 3所示的收集装置 4艮难满足 吸尘要求, 使吸尘器的适用性受到影响。  However, in the case where there is a lot of dust, the collecting device shown in Figs. 2 and 3 is difficult to meet the dust collecting requirements, and the applicability of the vacuum cleaner is affected.
因此,如何延长过滤器的使用寿命的基础上,提高吸尘器的工作效率, 提高收集装置的适用性, 是本领域技术人员目前需要解决的技术问题。 发明内容  Therefore, how to extend the service life of the filter, improve the working efficiency of the vacuum cleaner, and improve the applicability of the collecting device are technical problems that need to be solved by those skilled in the art.

Filtered through the second filter to ensure that the airflow into the power components is clean and free of impurities, thereby extending the life of the power components. Wherein, a wind deflector is arranged between the first filter and the second filter, so that the gas flowing out of the first filter cannot enter the second filter in the radial direction, but enters the second air inlet passage and the axial direction in the axial direction. The second dust collecting chamber finally enters the second filter. At the same time, at least one of the first air inlet passage and the second air inlet passage has a spiral structure, so that the dust moves into the air passage from the dust suction pipe, and gradually moves toward the space along the spiral air passage, from the first After coming out of the air passage and/or the second air inlet passage, under the inertia of high-speed rotation, the spiral line will continue to advance in the first dust collecting chamber and/or the second dust collecting chamber, and gradually become spatially Keep away from the trend at the end of the duct, thus moving away from the filter and reducing the possibility of dust adhering to the filter, so as to extend the life of the filter and reduce the frequency of filter maintenance, thus reducing the cleaning cost. Moreover, the filter can be kept clean for a long time to reduce the power consumption of the vacuum cleaner, reduce the noise of the vacuum cleaner, and improve the working efficiency of the vacuum cleaner.

The vent is cut, and the start and end points of any of the beveled vents radially or axially isolate the first filter and the second filter. The sealing plate can effectively prevent the airflow still carrying dust from flowing directly to the second filter through the top of the windshield, reducing the load of the second filter and prolonging the service life of the second filter. At the same time, since the first filter and the second filter are radially or axially isolated from the starting point and the end point of the bevel vent, the dust entering between the second filter and the wind deflector can be made from the second air inlet passage. The second dust collecting chamber can be inserted through the oblique vent, and the dust in the second dust collecting chamber can not enter the second filter through the oblique vent, further reducing the load of the second filter and enhancing the dust removal of the collecting device. effect.

Two or more spiral winds are formed inside the first filter 23, and the dust removal efficiency is further improved on the premise of increasing the dust removal area of the second filter 25.
因此, 本发明所提供的收集装置中, 第二过滤器 25可以为一个, 也可 以为两个或多个, 同理, 第三过滤器 31也为一个、 两个或多个。 当第二过 滤器 25为一个时, 第三过滤器 31可以为一个, 形成一个第一过滤器 23、 一个第二过滤器 25和一个第三过滤器 31的形式,第三过滤器 31也可以为 多个, 且多个第三过滤器 31均勾地分布于第二过滤器 25的内部; 当第二 过滤器 25为两个或多个时,第三过滤器 31可以与第二过滤器 25—一对应, 套设于第二过滤器 25的内部; 同时, 第二过滤器 25为两个或多个时, 第 三过滤器 31也可以为一个, 该第三过滤器 31设于距离动力部件进风口最 近的第二过滤器 25的内部,或者如第二种具体实施方式那样设于第二过滤 器 25的中心处, 确保进入动力部件的气流是经过第三过滤器 31过滤的气 体, 提高洁净度。  Therefore, in the collecting device provided by the present invention, the second filter 25 may be one, or two or more, and the third filter 31 may also be one, two or more.

请参考图 10至图 12, 图 10为本发明所提供挡风板与密封板第一种具 体实施方式的立体结构示意图; 图 11为图 10所示挡风板与密封板的俯视 图;图 12为本发明所提供挡风板与密封板第二种具体实施方式的立体结构 示意图。 Please refer to FIG. 10 to FIG. 12 , FIG. 10 is a first type of windshield and sealing plate provided by the present invention. FIG. 11 is a top view of the windshield and the sealing plate shown in FIG. 10; and FIG. 12 is a perspective structural view of the second embodiment of the windshield and the sealing plate provided by the present invention.
在第四种具体的实施方式中,挡风板 26的顶端固定连接有密封板 27 , 该密封板 27与挡风板 26至少一者具有连通第一过滤器 23和第二过滤器 25的斜切通风口, 且任一斜切通风口的起点和终点均沿径向或轴向隔离第 一过滤器 23和第二过滤器 25。 密封板 27可以有效避免仍携带有尘屑的气 流直接经挡风板 26的顶部回流至第二过滤器 25 , 减小第二过滤器 25的负 荷, 延长第二过滤器 25的使用寿命。 同时, 由于斜切通风口的起点和终点 均沿径向或轴向隔离第一过滤器 23和第二过滤器 25 , 可以使从第二进风 通道进入第二过滤器 25和挡风板 26之间的尘屑可以经斜切通风口甩入第 二集尘室 24, 在第二集尘室 24中的尘屑却不能经斜切通风口进入第二过 滤器 25 , 进一步减小第二过滤器 25的负荷, 增强收集装置的除尘效果。  In the fourth specific embodiment, the top end of the wind deflector 26 is fixedly connected with a sealing plate 27, and at least one of the sealing plate 27 and the wind deflector 26 has an oblique relationship between the first filter 23 and the second filter 25. The vents are cut, and the start and end points of either of the beveled vents isolate the first filter 23 and the second filter 25 radially or axially. The sealing plate 27 can effectively prevent the air flow still carrying the dust from flowing directly to the second filter 25 through the top of the wind deflector 26, reducing the load of the second filter 25 and prolonging the service life of the second filter 25. Meanwhile, since the first filter 23 and the second filter 25 are radially or axially isolated from both the start point and the end point of the bevel vent, the second filter 25 and the wind deflector 26 can be accessed from the second air inlet passage. The dust between the dust can be plunged into the second dust collecting chamber 24 through the oblique vent, and the dust in the second dust collecting chamber 24 cannot enter the second filter 25 through the oblique vent, further reducing the second filter 25 The load enhances the dust removal effect of the collection device.
显然, 密封板 27可以不存在, 即挡风板 26的顶端为通孔, 这样也能 实现本发明的目的, 也应该在本发明的保护范围之内。  Obviously, the sealing plate 27 may be absent, i.e., the top end of the wind deflector 26 is a through hole, which also achieves the object of the present invention and should be within the scope of the present invention.
请参考图 13 , 图 13为本发明所提供挡风板与密封板第三种具体实施 方式的立体结构示意图。  Referring to FIG. 13, FIG. 13 is a perspective structural schematic view showing a third embodiment of the windshield and the sealing plate provided by the present invention.
在第三种具体的实施方式中,本发明所提供的挡风板 26上设有斜切通 风口,斜切通风口的数目可以为多个,各斜切通风口沿挡风板 26的周向均 勾分布,且密封板 27具有向底端凹陷的中心凹坑。从第二进风通道中进入 挡风板 26与第二过滤器 25中间的灰尘可以经挡风板 26上的斜切通风口甩 出, 同时密封板 27的中心凹坑可以收集第二集尘室 24中的尘屑, 使在第 二集尘室 24中收集到的尘屑聚集在一起, 减少在第二集尘室 24中飞扬的 可能, 减少二次污染。 特别在吸尘管 21向上, 例如将该收集装置应用在便 携式吸尘器中, 当用于吸附天花板、 窗帘等高处的尘土时, 密封板 27上的 中心凹坑可以有效将收集到的尘土接住, 避免灰尘进入动力部件, 可以进 一步提高吸尘器的除尘效果。  In a third specific embodiment, the windshield 26 provided by the present invention is provided with a beveled vent, and the number of the beveled vents may be plural, and each of the beveled vents is distributed along the circumferential direction of the wind deflector 26, And the sealing plate 27 has a central recess recessed toward the bottom end. The dust entering the middle of the wind deflector 26 and the second filter 25 from the second air inlet passage can be pulled out through the oblique cut vent on the windshield 26, while the central recess of the sealing plate 27 can collect the second dust collecting chamber The dust in 24 collects the dust collected in the second dust collecting chamber 24, reduces the possibility of flying in the second dust collecting chamber 24, and reduces secondary pollution. Particularly in the upward direction of the dust suction pipe 21, for example, the collecting device is applied to a portable vacuum cleaner, and when used for absorbing dust at a height such as a ceiling or a curtain, the central pit on the sealing plate 27 can effectively collect the collected dust. , to prevent dust from entering the power components, can further improve the dust removal effect of the vacuum cleaner.
显然, 斜切通风口可以设在密封板 27上, 也可以设在挡风板 26上, 还可以同时设在密封板 27上和挡风板 26上, 只要斜切通风口能连通第一 过滤器 23和第二过滤器 25即可。 同时, 斜切通风口的起点和终点均沿径 向或轴向隔离第一过滤器 23和第二过滤器 25 , 以密封板 27为例, 可以理 解为密封板 27包括主体部和遮挡部(如图 10 ), 主体部与挡风板 26垂直, 遮挡部与主体部固定连接且呈预定角度, 主体部上设有若干通风口, 遮挡 部沿轴向挡住通风口, 形成斜切通风口。 密封板 27也可以为图 12所示的 结构,该密封板 27沿其厚度方向斜切,使尘屑不能沿轴向直接进入挡风板 26的内部。 斜切通风口设于挡风板 26上与设于密封板 27上类似, 只是沿 径向隔离第一过滤器 23和第二过滤器 25 , 在此不再赘述。 Obviously, the beveled vents may be provided on the sealing plate 27, or on the windshield 26, or on the sealing plate 27 and the wind deflector 26, as long as the beveled vents can communicate with the first The filter 23 and the second filter 25 are sufficient. At the same time, the starting point and the ending point of the beveling vents both radially and axially isolate the first filter 23 and the second filter 25, taking the sealing plate 27 as an example. It can be understood that the sealing plate 27 includes a main body portion and a shielding portion (such as 10), the main body portion is perpendicular to the wind deflector 26, the shielding portion is fixedly connected to the main body portion at a predetermined angle, and the main body portion is provided with a plurality of vents, and the shielding portion blocks the vent opening in the axial direction to form a bevel vent. The sealing plate 27 may also be of the structure shown in Fig. 12, which is chamfered in the thickness direction thereof so that dust does not directly enter the inside of the wind deflector 26 in the axial direction. The beveled vents are disposed on the wind deflector 26 similarly to those disposed on the sealing plate 27, except that the first filter 23 and the second filter 25 are radially separated, and will not be described herein.
请参考图 14, 图 14为本发明所提供第二过滤器和挡风板一种具体实 施方式的爆炸结构示意图。  Please refer to FIG. 14, FIG. 14 is a schematic diagram of an exploded structure of a second embodiment of the present invention and a wind deflector according to the present invention.
在一种优选的实施方式中, 第二进风通道的数目可以为两个或多个, 各第二进风通道均环绕第二过滤器 25的底端, 且其入口沿第二过滤器 25 的周向均匀分布。 如图 14所示, 第二过滤器 25的底部设有两个螺旋凸起 34, 两螺旋凸起 34均环绕第二过滤器 25 , 与挡风板 26配合形成两个螺旋 的进风通道; 其起点为第二进风通道的入口, 且两起点之间有预定距离, 具体可以以第二过滤器 25中心对称; 其终点均为第二过滤器 25的底端。 增多第二进风通道可以增加单位时间内第二过滤器 25的通风量,提高收集 装置的工作效率, 进而提高收集装置的适用性。 同时, 第二进风通道的入 口沿第二过滤器 25 的周向均匀分布可以使气流在收集装置中保持均匀分 布, 使气流更稳定。  In a preferred embodiment, the number of the second air inlet passages may be two or more, each of the second air inlet passages surrounds the bottom end of the second filter 25, and the inlet thereof is along the second filter 25. The circumferential direction is evenly distributed. As shown in FIG. 14, the bottom of the second filter 25 is provided with two spiral protrusions 34, both of which surround the second filter 25, and cooperate with the wind deflector 26 to form two spiral air inlet passages; The starting point is the entrance of the second air inlet passage, and there is a predetermined distance between the two starting points, specifically, the center of the second filter 25 is symmetrical; the end point is the bottom end of the second filter 25. Increasing the second air inlet passage can increase the ventilation amount of the second filter 25 per unit time, improve the working efficiency of the collecting device, and further improve the applicability of the collecting device. At the same time, the uniform distribution of the inlet of the second air inlet passage along the circumferential direction of the second filter 25 allows the air flow to be evenly distributed in the collecting device to make the air flow more stable.
另夕卜,图中第二进风通道由图中的螺旋凸起 34与挡风板 26配合形成, 显然,第二进风通道也可以在第二过滤器 25的底部由凹槽形成, 即在第二 过滤器 25的底部实体内部形成螺旋通道,这样也能满足本发明的需要,也 应该在本发明的保护范围之内。 但是, 图中所示的第二进风通道, 其结构 相对筒单, 易于加工实现, 有利于降低收集装置的生产成本。  In addition, the second air inlet passage is formed by the spiral protrusion 34 in the figure and the wind deflector 26. Obviously, the second air inlet passage can also be formed by the groove at the bottom of the second filter 25, that is, The formation of a spiral passage inside the bottom body of the second filter 25 also satisfies the needs of the present invention and is also within the scope of the present invention. However, the second air inlet passage shown in the figure has a relatively simple structure and is easy to process, which is advantageous for reducing the production cost of the collecting device.
请参考图 15 , 图 15为本发明所提供收集装置第五种具体实施方式的 结构示意图; 图中箭头所示方向为收集装置工作时气流的流动方向。  Referring to FIG. 15, FIG. 15 is a schematic structural view of a fifth embodiment of the collecting device according to the present invention; the direction indicated by the arrow in the figure is the flow direction of the airflow when the collecting device is in operation.
在第五种具体的实施方式中, 本发明所提供的收集装置还可以包括设 于第一过滤器 23 顶端的锥形导风罩, 该锥形导风罩的出口与第二集尘室 24连通。 收集装置工作时, 气流依次经过吸尘管 21、 第一进风通道、 第一 过滤器 23、 第二进风通道和锥形导风罩, 然后进入第二集尘室 24和第二 过滤器 25 , 即自第二进风通道流出的气体先经过锥形导风罩, 形成更强的 螺旋趋势, 使尘屑更多地在螺旋气流中远离第二过滤器 25 , 降低第二过滤 器 25的负荷,延长第二过滤器 25的使用寿命, 降低第二过滤器 25的更换 频次, 降低收集装置的维护成本。 In a fifth specific embodiment, the collecting device provided by the present invention may further include a conical air hood provided at the top end of the first filter 23, the outlet of the conical air hood and the second dust collecting chamber. 24 connected. When the collecting device is in operation, the airflow sequentially passes through the dust suction pipe 21, the first air inlet passage, the first filter 23, the second air inlet passage, and the tapered air hood, and then enters the second dust collecting chamber 24 and the second filter. 25, that is, the gas flowing out from the second air inlet passage first passes through the conical air hood to form a stronger spiral tendency, so that the dust is more away from the second filter 25 in the spiral air flow, and the second filter 25 is lowered. The load increases the service life of the second filter 25, reduces the frequency of replacement of the second filter 25, and reduces the maintenance cost of the collection device.
请参考图 16, 图 16为本发明所提供第二过滤器一种具体实施方式的 结构示意图。  Please refer to FIG. 16, FIG. 16 is a schematic structural view of a second embodiment of the second filter provided by the present invention.
在一种具体的实施方式中,本发明所提供的第二过滤器 25的过滤孔可 以是条状孔。经过第一过滤器 23过滤后, 大部分尘屑中发丝等体积较大的 杂质已经过滤掉,进入第二过滤器 25的可能性较小。 而条状孔相对于点状 孔其加工工艺更筒单, 成本更低, 适用于更多材质, 可以进一步降低收集 装置的加工难度和成本。 显然, 第一过滤器 23和第三过滤器 31也可以采 用条状孔型的过滤器。  In a specific embodiment, the filter holes of the second filter 25 provided by the present invention may be strip holes. After being filtered by the first filter 23, a large volume of impurities such as hair in most of the dust has been filtered out, and it is less likely to enter the second filter 25. The strip hole is more compact and less expensive than the point hole, and is suitable for more materials, which can further reduce the processing difficulty and cost of the collecting device. Obviously, the first filter 23 and the third filter 31 can also adopt a strip-shaped filter.
除了上述收集装置, 本发明还提供一种包括上述收集装置的吸尘器, 该吸尘器的动力部件与收集装置中的第二过滤器 25的出口端连接,动力部 件工作时,在收集装置中形成负压,使尘屑进入第一集尘室 22和第二集尘 室 24, 达到吸尘清洁的技术效果。 吸尘器其他各部分的结构请参考现有技 术, 本文不再赘述。  In addition to the above collecting device, the present invention also provides a vacuum cleaner including the above collecting device, the power component of the vacuum cleaner is connected to the outlet end of the second filter 25 in the collecting device, and a negative pressure is formed in the collecting device when the power component operates The dust enters the first dust collecting chamber 22 and the second dust collecting chamber 24 to achieve the technical effect of vacuum cleaning. Please refer to the existing technology for the structure of other parts of the vacuum cleaner, and will not repeat them in this article.
