Description

旋风手持真空吸尘装置 Handheld cyclonic vacuum cleaning apparatus

技术领域 FIELD

本发明涉及一种可充电手持式真空吸尘器,更具体地涉及一种将平行旋风器用作分离装置的可充电手持式真空吸尘器。 The present invention relates to a rechargeable handheld vacuum cleaner, and more particularly, to a rechargeable handheld vacuum cleaner is used as a method of parallel cyclone separation apparatus.

背景技术 Background technique

典型的手持式真空吸尘器具有与叶轮相连接的马达,所述马达可由主电源或可充电电池驱动,所述叶轮能产生一气流,所述气流先通过吸嘴,再流经灰尘杯然后进入叶轮。 Typical handheld vacuum cleaner having a motor and an impeller connected to the motor by the main drive power supply or a rechargeable battery, the impeller generates an air flow, the air flow through the first nozzle, and then flows through the dust cup and then enters the impeller . 在灰尘杯内,大多数会设置简单的过滤器,所述过滤器有时与空气的旋风运动配合在一起应用,用于使污垢和灰尘从空气中分离。 In the dust cup, it will be arranged most simple filter, the filter may be applied together with the cyclonic motion of the air, for separating dirt and dust from the air. 另一过滤器可设置在叶轮之后,用于在废气排出吸尘器之前过滤来自马达的细小灰尘或碳尘。 Another filter may be provided after the impeller for filtering fine dust or carbon dust from the motor prior to discharging the exhaust gas cleaner.

在灰尘杯中设置简单的过滤器的典型手持式真空吸尘器的一个问题是,当过滤器接收过多灰尘时,过滤器会很快地被堵塞起来,从而降低了吸尘器的性能。 Simple filter is provided in the dust cup of a handheld vacuum cleaner typical problem it is that, when receiving excessive dust filter, the filter will quickly be clogged up, thereby reducing the performance of the vacuum cleaner. 这样使得用户必须拆除并清洁所述过滤器,这是一个令用户感到不方便的步骤。 Such that the user must remove and clean the filter, which is a step to make the user feel inconvenient.

一个相连带的问题是,过滤器通常设置在灰尘杯内,而为了清洁灰尘杯,用户必须首先从灰尘杯移走过滤器。 Connected with a problem that the filter is usually disposed in the dust cup, and the cup in order to clean the dust, the user must first remove the filter from the dust cup. 这个步骤常常会令环境变脏,并且可能弄脏用户的手,从而造成卫生问题。 This step will often make the environment dirty, dirty and possibly the user's hand, causing health problems.

在配备了所谓旋风作用的典型手持式真空吸尘器的另一问题是,低效能的旋风作用使得大部分污垢和灰尘积聚于过滤器之上。 Equipped with a so-called cyclone effect Another problem with a typical handheld vacuum cleaner is inefficient cyclonic action so that the majority of dirt and dust accumulates on top of the filter. 随着过滤器被越来越多的灰尘堵塞,吸力相应逐渐丧失。 As more and more clogged the filter dust, corresponding gradual loss of suction. 在所述的吸尘器中,用户仍必须经常拆除和清洁过滤器,从而令到应用旋风器的目的被质疑。 In the vacuum cleaner, the user still must frequently remove and clean the filter, so that the application purpose of the cyclone is questioned.

旋风式分离在本领域中是公知的。 In the cyclone-like separator it is well known in the art. 它应用在真空吸尘器中也是公知的(例如,在EP 0042723B中)。 Its use in the vacuum cleaner is also known (e.g., in the EP 0042723B). 在上游设置单个旋风器和在下游设置多个平行旋风器的应用亦已经在US 3425192中被描述。 Providing a single cyclone and a plurality of parallel cyclones downstream of the application it has been also described in US 3425192 in the upstream. 应用两个或多个平行旋风器可带出较少的总空气阻力和改善旋风式分离性能。 Application of two or more parallel cyclones may bring out less total air resistance and improving the separation performance of the cyclone. 改善的分离性能源于以下的原理,对于一给定的吸入源,一个空气路径可被分成几个具有较小截面面积的空气路径,而又同时保持相同的总流速。 Improved performance stems from the separation principle, for a given suction source, an air path may be divided into several air path having a smaller cross-sectional area, but while maintaining the same total flow rate. 这意味着,每个单独的旋风器的内径可以减小,这样,当空气中的颗粒以旋转方式通过旋风器时便有较大的径向加速度。 This means that the inner diameter of each individual cyclone can be reduced, so that, when the particles in the air in a rotating manner by the cyclone will have a larger radial acceleration. 因此,相对于只使用单一个旋风器,使用多个旋风器可令较细小的灰尘也能从空气中分离。 Thus, with respect to only a single cyclone, a plurality of cyclones may also make finer dust separated from the air. 但由于真空吸尘器所吸入的颗粒大小不一,所述设计也存在实际缺点。 However, due to the suction of the vacuum cleaner particle sizes, there are practical disadvantages to the design. 一些体积大于进入个别旋风器的空气路径的颗粒会被卡住。 Some volume greater than particles enter the individual cyclone air paths get stuck. 为了克服此问题,单个大的预旋风器后面连接多个较小的平行的旋风器的布置已被使用。 To overcome this problem, the back of a single large cyclone pre-connected cyclones arranged in parallel multiple smaller has been used.

在此主题上已有大量的专利被公布。 On this theme has a large number of patents have been published. EP 0042723讨论了单个旋风器或串联布置的两个旋风器。 EP 0042723 discusses a single cyclone, or two cyclones arranged in series. GB 2372435描述了多个分离器、将它们连接的空气路径、和与真空吸尘器的外侧表面的关系的布置。 GB 2372435 describes a plurality of separators, an air path which they are attached, and the outer surface of the arrangement relationship with the vacuum cleaner. 而WO 00/24519是以更窄的范围描述空气路径的特性的另一实例。 WO 00/24519 is another example of the described characteristics of the air path narrower range.

市场上存在着双旋风分离器真空吸尘器,一个是直立方式,一个是柱体方式。 There is a double cyclone vacuum cleaners on the market, one is the upright position, the column is a way. 两个都以平行布置的双旋风分离器为特征,而且无上游分离器阶段。 Two double cyclones are arranged in parallel is characterized, and no upstream separator stage. 两个旋风器具有直的本体,并且与单独的集尘室连通。 Two cyclone has a straight body and in communication with a separate dust collecting chamber. 通向旋风器的空气入口为T形,从而使空气分成两股个别的气流并沿切线方向进入这两个旋风器之中。 Leading to the cyclone air inlet T-shaped, so that the air flow into two individual and enters into the two cyclone tangentially. US 3425192也描述了于第二阶段中应用直而平行的旋风器。 US 3425192 also describes the application of the second phase is straight and parallel to the cyclone. 所以,平行的旋风器在本领域中是已知的,而本发明亦是建基于相关的运作原理。 Therefore, parallel cyclones are known in the art, and the present invention is founded on the principle of operation is also relevant.

为了获得良好的吸入和旋风性能,完全密封的空气路径是重要的。 To obtain good suction performance and a cyclone, an air path is completely sealed important. 所以在灰尘杯6和主壳体1之间设置了过滤器密封条22和集尘室密封条19以确保没有空气泄漏。 Therefore, between the main housing 6 and the dust cup 1 is provided with a filter seal 22 sealing strip 19 and the dust collection chamber to ensure that no air leaks. 参看图4,当灰尘杯6连接到主壳体1上时,过滤器18位于表面34和保护杆50之间。 Referring to Figure 4, when the dust cup 6 is connected to the main housing 1, the filter 18 is positioned between the surfaces 34 and 50 protect the rod. 并且,围绕表面34的过滤器密封条22与接触表面33相接触。 The sealing strip 22 is in contact with the contact surface 33 around the surface 34 of the filter. 由于过滤器密封条22由弹性材料制成,所以过滤器密封条22和接触表面33之间不存在空气的泄漏。 Since the filter 22 is made of a weather strip of an elastic material, so there is no leak filter seal between the air 22 and the contact surface 33. 当灰尘杯6连接至主壳体1时,空气会聚室60便在分离器顶部65和漏斗形入口27之间形成,来自个别的旋风器的空气路径在其中会聚成单一的空气路径,并且被引导到漏斗形入口27之中。 6 when the dust cup 1 is connected to the main housing, an air chamber 60 will converge at the top of the separator 65 and 27 is formed between the funnel-shaped inlet, an air path from the individual cyclone in which air converge into a single path, and is being guided to the inlet funnel 27. 与此同时,凸面36与集尘室开口35啮合。 At the same time, the dust collecting chamber 36 and the convex engagement opening 35. 由于凸面36和集尘室开口35之间存在着富弹性的集尘室密封条19,因此空腔30和空腔31被密封。 Rich dust collecting chamber due to the presence of the elastic sealing strip 19 between the convex surface 35 and the dust collection chamber opening 36, so the cavity 30 and the cavity 31 is sealed.

在本发明中,灰尘杯6中包括了具有两个平行旋风器的旋风器系统。 In the present invention, the dust cup 6 includes a cyclone system with two parallel cyclones. 如图5和图6中所示,带有灰尘的空气透过入气通道开口8,经入气通道20流向T形双分叉处51,在这里,气流被分成两股。 As shown in FIGS. 5 and 6, the air with dust through the air passage opening 8, into the air flow through the passage 20 T-shaped bifurcated at 51, where the gas flow is divided into two. 如图5中所示,有一壁55存在于T形双分叉处51的下面,这使得带有灰尘的空气分成两股气流,并且分别通过旋风器开口40和旋风器开口41进入旋风器46和旋风器47。 As shown in FIG. 5, there is present in the wall 55 below bifurcated at T-51, which makes the dust laden air into two streams, respectively 41 and enters the cyclone 46 by the cyclone and the cyclone 40 openings and the cyclone 47. 所述壁55优选是平坦的,以避免污垢物质在此处被卡住。 The wall 55 is preferably flat to avoid fouling substances stuck here. 如图6中所示,带有灰尘的空气沿切线方向流到旋风器47和旋风器46的内表面上,并且分别在个别旋风器内形成涡流43和涡流42。 As shown in FIG. 6, the air in the tangential direction with a dust cyclone 47 and flows on the inner surface of the cyclone 46, and 43 are respectively a vortex and a vortex 42 within cyclone individual. 这使得比空气重的灰尘颗粒透过离心力的作用移向涡流外面,这现象通常称为旋风式分离,并且为本领域的技术人员所公知。 This makes the dust particles heavier than air vortex toward the outside through centrifugal force, which phenomenon is commonly referred to cyclonic separation, and known to those skilled in the art.

下面描述其中任何一个旋风器中的气流路径。 Will be described below wherein the air flow path of any one cyclone. 如图5中所示,在旋风器46内的末端壁56上存在涡流停止器64。 As shown in FIG. 5, the presence of the vortex stop 64 on the end wall 56 of the cyclone 46. 涡流停止器64和涡流42的中心占是同心的,因此,处于涡流42中心,较为清洁的空气将首先与涡流停止器64碰撞,气流随即反向到相反方向并进入回流管37,同时间,灰尘39继续向着末端壁56流动并沿切线方向逸入集尘室9。 The central vortex vortices 42 and stop 64 are concentric account, therefore, at the center of the vortex 42, a more clean air to the vortex stopper 64 first impact the gas flow to the opposite direction and then reverse into the return pipe 37, the same time, dust 39 flows continue toward end wall 56 and a tangential escape in the dust collecting chamber 9. 如前所述,集尘室9经由灰尘释放孔连接至旋风器本体。 As described above, the dust discharge hole 9 via the dust collecting chamber is connected to the cyclone body. 图中示出灰尘39透过惯性作用,经旋风器末端44逸入空腔30。 39 is shown the dust through inertia, Yi by the cyclone 44 into the tip cavity 30. 在正常操作期间,灰尘杯6连接到主壳体1上,从而使空腔30被密封。 During normal operation, the dust cup 6 is connected to the main housing 1, so that the cavity 30 is sealed. 图6也示出旋风器47内部的构造和气流。 FIG 6 also shows the internal structure of the cyclone 47 and the gas flow. 在旋风器47内,存在旋风器开口41、旋风器末端45、和位于末端壁57上的涡流停止器63。 In the cyclone 47, the presence of the opening 41 of the cyclone, the cyclone tip 45, located on the end wall 57 of the vortex 63 is stopped. 用涡流43表示的旋风式分离的原理也与旋风器46中相同。 Cyclonic principle of separation vortex 43 is also represented by the same 46 in the cyclone.

图6示出在每个旋风器内都存在具有锥形端的回流管。 Figure 6 shows the return pipe are present having a tapered end in each cyclone. 以旋风器46为例,回流管37具有锥形端58。 In an example cyclone 46, the return pipe 37 has a tapered end 58. 在一个优选实施例中,锥形端58具有几个狭缝54,所述狭缝54允许气流进入回流管37。 In a preferred embodiment, the tapered end 58 having several slits 54, the slits 54 allows airflow into the return pipe 37. 狭缝的另一功能是充当为一粗略的安全过滤器,确保没有大颗粒进入回流管37内。 Another function is to act as a slit coarse safety filter to ensure that no large particles 37 into the return pipe. 并且,例如网格等其它过滤装置可用于代替狭缝或与狭缝组合使用以提供更好的过滤效果。 And, for example, the filter mesh, and other devices may be used in place of the slit or slits used in combination with better filtering effect. 在旋风器47内,设有狭缝53的锥形端59具有相同构造。 In the cyclone 47, a slit 53 of the tapered end 59 has the same configuration.

如图6中所示,被清洁过的空气通过分别的回流管末端48和回流管末端49离开旋风器46和旋风器47。 As shown in FIG. 6, the cleaned air passes through the return pipe 48 at each end thereof and the return conduit 49 the end away from the cyclone 46 and a cyclone 47. 分离器顶部65和漏斗形入口27形成空气会聚室60,以会聚旋风器46和旋风器47的下游空气路径,使之成为单一空气路径。 Top separator 65 and the funnel-shaped inlet 27 converge to form an air chamber 60 to the air path downstream of the converging cyclone 47 and the cyclone 46, into a single, air paths. 过滤器18位于灰尘杯6的后部位置处。 Filter 18 is located at a rear position 6 of the dust cup.

在本发明中,旋风器系统被设计成为将灰尘39收集于独立的集尘室9,且所述集尘室9远离旋风器46和旋风器47。 In the present invention, the cyclone system is designed to separate the dust 39 collected in the dust collecting chamber 9 and 9 remote from the cyclone dust collecting chamber 46 and cyclone 47. 在图5中可看到旋风器系统和集尘室9的构造的清楚图示,而图8示出传统的旋风器系统的灰尘存放方法与本发明的旋风器系统不同。 Can be seen clearly illustrating the configuration of a cyclone and baghouse system 9 in FIG. 5, and FIG. 8 shows a conventional cyclone dust storage system and method of the present invention, the cyclone system are different. 在传统的旋风器系统中,一般而言,不存在独立的集尘室,而马达前过滤器32则位于旋风器本体68内。 In a conventional cyclone system, in general, there is no separate dust collecting chamber, and the front motor filter 32 is located at the cyclone body 68. 由此看到,旋风器本体和集尘室其实是相同的部分。 Thus seen, the cyclone body and the dust collection chamber is in fact the same parts. 这使得越来越多的灰尘39积聚于过滤器之上,而并没有真正透过旋风作用被分离。 This makes more and more dust accumulates on top of the filter 39, and are not actually separated via cyclonic action. 本发明采用了远离旋风器设置的独立灰尘存放器,并配合高效的旋风器系统。 The present invention uses a separate cyclone dust away from the receiving means provided, and with high efficiency cyclone system. 结果,大多数的灰尘将透过旋风器而被分离,只有少数的灰尘(主要是非常微小的灰尘)会经过所述系统进入过滤器中。 As a result, most of the dust will be separated through cyclone dust only a few (mostly very fine dust) will pass through the filter into the system. 因此,用户将不必经常清洁过滤器,并体验到恒定的吸力,以及更便利的清洁灰尘杯的方法。 Thus, the user would not have to frequently clean the filter, a constant suction and experience, and more convenient method of cleaning the dust cup.

本发明提供了干净而快速的灰尘去除过程,这与传统的手持式真空吸尘器相比是一项改进。 The present invention provides a clean and quick dust removal process which compared to traditional handheld vacuum cleaner is an improvement. 具有集尘室开口35的集尘室9与真空吸尘装置的灰尘杯6一起设置。 Dust collecting chamber having a dust collecting chamber 9 is provided with an opening 35 of the dust cup of the vacuum suction device 6. 因此,只要将灰尘杯6简单地从主壳体1分离,便可从集尘室9排出积聚在空腔30和空腔31内的灰尘39。 Therefore, if the dust cup 6 easily separated from the main body 1, the dust 39 can accumulate in the discharge cavity 30 and the cavity 31 from the dust collecting chamber 9. 这令到清洁集尘室9变成为更方便和更卫生的过程,因为用户不必接触或去除任何与灰尘所接触的部分或过滤器。 This makes the cleaning of the dust collecting chamber 9 becomes more convenient and hygienic process, because the user does not have to touch or remove any part of or in contact with the filter dust. 用于替代集尘室开口35的另一开口装置可以是位于集尘室9上的可移动的门。 Another alternative for the dust collecting chamber opening device opening 35 may be located on the dust collecting chamber 9 the movable door.

在本发明中,一些有用的配件工具被设计出来,以提高真空吸尘装置的功能。 In the present invention, useful tool accessories is designed to improve the function of the vacuum suction apparatus. 图7示出把杆67和地板吸嘴66。 Figure 7 shows the bar 67 and the floor nozzle 66.
