技术领域technical field

本发明涉及一种真空吸尘器，更具体的是，本发明涉及一种真空吸尘器，其能够通过使用由吸尘器主体内部驱动的电机产生的吸力从待清洁表面吸入带有灰尘的空气，从吸入的空气中过滤灰尘，并将净化的空气排放至吸尘器主体外部。The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of sucking dust-laden air from a surface to be cleaned by using suction generated by a motor driven inside the main body of the cleaner, from the sucked air Dust is filtered in the middle of the vacuum cleaner, and the purified air is discharged to the outside of the main body of the vacuum cleaner.

背景技术Background technique

真空吸尘器可大致分为立式吸尘器和罐式吸尘器。立式吸尘器具有吸入口组件直接连接至吸尘器主体，而不需要使用单独的软管或延伸管的结构。这种立式吸尘器利用其重量进行清洁，并因此在清洁诸如地毯的纤维物方面很有效。罐式吸尘器具有与立式吸尘器不同的结构，其中吸入口组件与吸尘器主体流体连通。由于吸入口组件相对自由操作，所以当立式吸尘器无法进入诸如狭窄地方或阶梯的地方时，罐式吸尘器会更有效。Vacuum cleaners can be broadly classified into upright vacuum cleaners and canister vacuum cleaners. The upright vacuum cleaner has a structure in which the suction assembly is directly connected to the main body of the vacuum cleaner without using a separate hose or extension pipe. Such upright cleaners use their weight to clean and are therefore effective in cleaning fibrous objects such as carpets. Canister vacuum cleaners have a different construction than upright vacuum cleaners in that the suction inlet assembly is in fluid communication with the cleaner body. Because the suction assembly is relatively free to operate, canister vacuums are more effective in places where an upright vacuum cannot access such as narrow places or steps.

另外，如美国专利文件No.53096和No.5524321公开内容，已建议一种具有升降结构的真空吸尘器，以结合罐式和立式吸尘器的优点。该升降结构使得吸尘器主体能够与吸入口组件分离。In addition, as disclosed in US Patent Documents No. 53096 and No. 5524321, a vacuum cleaner having a lifting structure has been proposed to combine the advantages of the canister type and the upright cleaner. The lifting structure enables the main body of the vacuum cleaner to be separated from the suction port assembly.

然而，这种可转换的真空吸尘器具有一些缺陷。通常，立式吸尘器需要从吸入口组件纵向延伸的分离支撑框架，罐式需要用户在分离位置收起诸如延伸管或软管的部件，供以后使用。However, such convertible vacuum cleaners have some drawbacks. Typically, upright vacuums require a separate support frame that extends longitudinally from the suction assembly, and canisters require the user to stow away components such as extension tubes or hoses in a separate location for later use.

由于不同的流体路径基于真空吸尘器是在直立模式下还是在罐式模式下操作而形成在吸入口组件和吸尘器主体之间，所以可转换的真空吸尘器还需要流体路径转换结构，用以改变立式和罐式之间的流体路径。分离流体路径转换结构的需要使得结构变得更加复杂。另外，当用户使用罐式模式时，由于用户不得不将延伸管从吸尘器主体中分离并将其重新连接至吸尘器主体的吸入口，所以用户感到不便。Convertible vacuum cleaners also require fluid path switching structures to change the upright position since different fluid paths are formed between the suction inlet assembly and the cleaner body based on whether the vacuum cleaner is operating in upright or canister mode. Fluid path between tank and tank. The need for separate fluid path transition structures further complicates the structure. In addition, when the user uses the canister mode, the user feels inconvenience because the user has to detach the extension pipe from the cleaner main body and reconnect it to the suction port of the cleaner main body.

另一个缺陷在于：真空吸尘器通常被制成适合于成人高度的用户使用，这阻碍了用户存放吸尘器的自由度。Another disadvantage is that vacuum cleaners are usually made for users of adult height, which hinders the user's freedom of storage of the vacuum cleaner.

发明内容Contents of the invention

本发明的典型实施例克服上述的不足和以上未提到的其他缺陷。因此，本发明目的在于提供一种立式和罐式可切换式的真空吸尘器，其易于被收起并能够使用户使用的便利性最大化。Exemplary embodiments of the present invention overcome the above disadvantages and other disadvantages not mentioned above.

如果真空吸尘器处于直立模式，延伸管保持与旋转连接器连接，并相对于吸入口组件旋转，以允许吸尘器主体相对于吸入口组件转动。If the vacuum cleaner is in the upright mode, the extension tube remains connected to the swivel connector and rotates relative to the suction port assembly to allow rotation of the cleaner body relative to the suction port assembly.

真空吸尘器可通过两个步骤的操作从直立模式切换到罐式模式，该两个步骤的操作包括将延伸管从旋转连接器分离，以及将附件喷嘴连接至延伸管的一端。The vacuum cleaner can be switched from the upright mode to the canister mode in a two-step operation that includes detaching the extension tube from the swivel connector and connecting the accessory nozzle to one end of the extension tube.

本发明另一方面提供了一种真空吸尘器，其包括吸入口组件，该吸入口组件包括吸入口以及吸入通道，用于从待清洁对象吸入带有灰尘的空气；容纳灰尘分离单元和与灰尘分离单元连接的电机的吸尘器主体；操作手柄组件，该操作手柄组件中的一端通过软管与吸尘器主体流体连通，另一端与延伸管流体连通，该延伸管可与吸尘器主体连接或分离；以及携带手柄组件，该携带手柄组件沿吸尘器主体滑动，以与操作手柄组件一起或单独增加长度。如果真空吸尘器处于直立模式，延伸管与吸入口组件流体连通，被用作空气通向吸尘器主体的通道，并支撑吸尘器主体，如果真空吸尘器处于罐式模式时，延伸管从吸入口组件分离。Another aspect of the present invention provides a vacuum cleaner, which includes a suction port assembly including a suction port and a suction channel for sucking dust-laden air from an object to be cleaned; accommodating a dust separation unit and separating from dust A vacuum cleaner body with a unit-connected motor; an operating handle assembly in which one end is in fluid communication with the vacuum cleaner body through a hose and the other end is in fluid communication with an extension tube that can be attached to or detached from the vacuum cleaner body; and a carrying handle Assembly, the carrying handle assembly slides along the main body of the vacuum cleaner to increase in length together with the operating handle assembly or separately. The extension tube is in fluid communication with the suction inlet assembly, is used to channel air to and supports the vacuum cleaner body if the vacuum cleaner is in the upright mode, and is detached from the suction inlet assembly if the vacuum cleaner is in the canister mode.

携带手柄组件可包括主体部件，手柄形成在所述主体部件中，并且所述操作手柄组件插入在所述主体部件的后侧中；滑杆，所述滑杆形成在所述吸尘器主体中，以沿吸尘器主体的纵向滑动；以及操作单元，所述操作单元与滑杆连接，所述操作单元被形成在所述主体部件上，以被部分的暴露在所述吸尘器主体的外部。操作单元选择性地锁定和解锁所述滑杆和所述操作手柄组件。The carrying handle assembly may include a main body part in which a handle is formed and the operating handle assembly is inserted in a rear side of the main body part; a slide bar formed in the cleaner main body to sliding along the longitudinal direction of the cleaner main body; and an operating unit connected to the slide bar, the operating unit being formed on the main body part to be partially exposed outside the cleaner main body. An operating unit selectively locks and unlocks the slide bar and the operating handle assembly.

操作单元通过转动主体部件的暴露部分解锁操作手柄组件，并通过按压主体部件的暴露部分解锁滑杆。The operating unit unlocks the operating handle assembly by turning the exposed part of the main body part, and unlocks the slide bar by pressing the exposed part of the main body part.

操作单元可包括杆固定壳体，该杆固定壳体固定形成在主体部件中，以支撑滑杆；旋转部件，其可旋转形成于杆固定壳体的上部，并包括从吸尘器主体后侧突出的插销，以被插入至操作手柄组件的锁定孔；按钮部件，在该按钮部件中，其上部从主体部件的上表面突出，下部设置在旋转部件内部，以允许所述按钮部件沿所述旋转部件单独竖直地地移动；以及弹性构件，用于弹性支撑按钮部件，以允许按钮部件相对于杆固定壳体扭曲和压缩。The operation unit may include a rod fixing case fixedly formed in the main body part to support the slide rod; a rotating part rotatably formed in the upper part of the rod fixing case and including a a latch to be inserted into the locking hole of the operating handle assembly; a button part in which the upper part protrudes from the upper surface of the main body part and the lower part is provided inside the rotating part to allow the button part to move along the rotating part individually vertically moving; and an elastic member for elastically supporting the button part to allow twisting and compression of the button part relative to the lever fixing case.

因此，提供了一种具有简单结构的可切换的真空吸尘器，当在直立模式下操作时，延伸管支撑吸尘器主体，并因此消除用于支撑吸尘器主体的分离框架的需要，并且在立式和罐式模式下，在吸入口组件和吸尘器组件之间使用相同的空气通道，因此消除用于切换分离流动通道的需要。Therefore, there is provided a switchable vacuum cleaner having a simple structure, the extension pipe supports the cleaner main body when operating in the upright mode, and thus eliminates the need for a separate frame for supporting the cleaner main body, and is available in upright and canister In mode, the same air passage is used between the suction assembly and the cleaner assembly, thus eliminating the need for switching separate flow passages.

另外，通过接合延伸管和吸入口组件或使延伸管从吸入口组件分离实现立式和罐式模式之间的简单和快速的切换。Additionally, simple and quick switching between upright and canister modes is achieved by engaging or detaching the extension tube and suction port assembly.

另外，提供一种可延伸和可伸缩的操作手柄组件，并且当真空吸尘器处于操作状态时，操作手柄组件延伸，当真空吸尘器收起时，操作手柄组件被收回。结果，可减小真空吸尘器的总体高度，并因此能够不用太过担心收起真空吸尘器后的空间限制。In addition, an extendable and retractable operating handle assembly is provided, and when the vacuum cleaner is in an operating state, the operating handle assembly is extended, and when the vacuum cleaner is stowed, the operating handle assembly is retracted. As a result, the overall height of the vacuum cleaner can be reduced, and thus the space constraints of stowing the vacuum cleaner can be less of a concern.

具体实施方式Detailed ways

在说明书中限定的诸如详细结构和元件的内容为帮助全面理解本发明实施例而提供。因此，本领域技术人员可以理解，在不背离本发明的范围和精神的情况下可以对此实施例进行变更。同样，为了清楚和简明，将忽略对已知功能和结构的描述。Matters such as detailed structures and elements defined in the description are provided to assist in a comprehensive understanding of the embodiments of the present invention. Accordingly, those skilled in the art will appreciate that changes may be made in this embodiment without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

参考图1和2，根据本发明第一典型实施例的真空吸尘器，其包括清洁单元10和吸入口组件20。清洁单元10可从吸入口组件20分离，并分离地使用。Referring to FIGS. 1 and 2 , a vacuum cleaner according to a first exemplary embodiment of the present invention includes acleaning unit 10 and asuction port assembly 20 . Thecleaning unit 10 is detachable from thesuction port assembly 20 and used separately.

清洁单元10可包括吸尘器主体11，软管13，操作手柄组件15，以及延伸管17。Thecleaning unit 10 may include acleaner body 11 , ahose 13 , anoperating handle assembly 15 , and anextension pipe 17 .

吸尘器单元11可包括吸入电机12a，吸入电机12a用于在吸尘器主体11内部产生吸力；以及灰尘分离单元12b，灰尘分离单元12b用于通过吸入电机12a产生的吸力，从通过软管13吸入的空气中分离灰尘，并收集分离的灰尘。灰尘分离单元12b可适当地具有气旋结构，用于利用离心力将灰尘从吸入的空气中分离。然而，可以理解的是也可以采用其他替代方式。例如，可安装灰尘袋以收集灰尘。Thecleaner unit 11 may include asuction motor 12a for generating suction inside the cleanermain body 11; Separation of dust and collecting the separated dust. Thedust separation unit 12b may suitably have a cyclone structure for separating dust from the sucked air by centrifugal force. However, it is understood that other alternatives may also be used. For example, dust bags can be fitted to collect dust.

吸尘器主体11可包括一对锁扣接合部件14a，14b，锁扣接合部件14a，14b在吸尘器主体11的一侧上竖直地对齐，用于与延伸管17锁扣接合。这里，并不限制锁扣接合部件的数目，但是可根据需要改变。例如，三个或更多锁扣接合部件，或者甚至单独一个锁扣接合部件都可形成于吸尘器主体11上，以支持吸尘器主体11和延伸管17的牢固接合。Thecleaner body 11 may include a pair ofsnap engagement members 14 a , 14 b vertically aligned on one side of thecleaner body 11 for snap engagement with theextension tube 17 . Here, the number of snap engaging parts is not limited, but may be changed as needed. For example, three or more snap engagement features, or even a single snap engagement feature, may be formed on thecleaner body 11 to support secure engagement of thecleaner body 11 and theextension tube 17 .

吸尘器主体11还可包括形成于上侧上的携带手柄11a，用于从吸入口组件20分离吸尘器主体11时，可由用户夹持，并携带吸尘器主体11。吸尘器主体11包括形成在下表面上的多个辅助轮19，用以帮助吸尘器主体11更平滑地沿地板移动。Thecleaner body 11 may further include a carryinghandle 11 a formed on the upper side for being gripped by a user and carrying thecleaner body 11 when thecleaner body 11 is separated from thesuction port assembly 20 . Thecleaner body 11 includes a plurality ofauxiliary wheels 19 formed on a lower surface to help thecleaner body 11 move more smoothly along a floor.

软管13可由柔性材料制造。软管13的一端可连接至吸尘器主体11的一侧，且软管13与灰尘分离单元12b流体连通。Thehose 13 can be manufactured from a flexible material. One end of thehose 13 may be connected to one side of the cleanermain body 11, and thehose 13 is in fluid communication with thedust separating unit 12b.

操作手柄组件15包括紧握部件15a，以被用户紧握。操作手柄组件15排列在软管13和延伸管17之间，以与两者流体连通。The operatinghandle assembly 15 includes agripping part 15a to be gripped by a user. Anoperating handle assembly 15 is arranged between thehose 13 and theextension tube 17 to be in fluid communication with both.

延伸管17扮演引导通道的角色，该引导通道将来自吸入口组件20或附件喷嘴30(图3)的灰尘引向清洁单元10。延伸管17可具有伸缩结构，从而当真空吸尘器在罐式模式下操作时，可调节长度以供使用。延伸管17可和吸尘器主体11至少一样长，以使用户能够在直立模式下来回轻松地按压吸入口组件20。Theextension pipe 17 plays the role of a guide passage that guides dust from thesuction inlet assembly 20 or the accessory nozzle 30 ( FIG. 3 ) to thecleaning unit 10 . Theextension tube 17 may have a telescoping structure so that the length can be adjusted for use when the vacuum cleaner is operating in the canister mode. Theextension tube 17 may be at least as long as thecleaner body 11 to enable the user to easily press thesuction port assembly 20 back and forth in the upright mode.

吸入口组件20可具有形成在下表面上的吸入端口20a，吸入端口20a吸入来自待清洁表面的空气和灰尘；一对主轮21a，21b，主轮21a，21b辅助吸入口组件20沿待清洁表面的运动；以及位于后侧中间的铰接部件23。Thesuction inlet assembly 20 may have asuction port 20a formed on the lower surface, which sucks air and dust from the surface to be cleaned; a pair ofmain wheels 21a, 21b, which assist thesuction inlet assembly 20 along the surface to be cleaned. and the hingedpart 23 in the middle of the rear side.

铰接部件23包括铰接轴23a，铰接轴23a相对于铰接部件23的前进方向以垂直关系设置，并具有与吸入口组件20可转地接合的两端；以及与铰接轴23a相接合的连接管23b。连接管23b与延伸管17可分离地连接，并在大约为90°的旋转角度(θ)内旋转。Thehinge part 23 includes ahinge shaft 23a, which is arranged in a vertical relationship with respect to the advancing direction of thehinge part 23, and has both ends rotatably engaged with thesuction port assembly 20; and a connectingpipe 23b engaged with thehinge shaft 23a. . Theconnection pipe 23b is detachably connected to theextension pipe 17, and rotates within a rotation angle (θ) of approximately 90°.

接管23b的旋转角度(θ)被设定为：在连接管23b处于与吸入口组件20所位于的表面成平行关系时，允许接管23b在吸入口组件20前以大约110°旋转。于是，吸尘器主体11在直立模式下相对于与地板垂直的线略微倾斜，使得吸尘器主体11的重心从吸入口组件20的后部切换至前部，因此允许吸尘器主体11牢固放置于吸入口组件20的上侧。当真空吸尘器不进行清洁操作时，这种结构防止吸尘器主体11在地板上转动，以及防止吸尘器主体11被诸如施加到吸尘器上的振动的外力影响损坏。还可采用在吸尘器主体11的下端和吸入口组件20的上端上设置的用于锁扣接合的锁扣部件的实例，用于在适当位置固定吸尘器主体11。The angle of rotation (θ) of thenozzle 23b is set to allow thenozzle 23b to rotate about 110° in front of theinlet assembly 20 when the connectingtube 23b is in a parallel relationship to the surface on which theinlet assembly 20 is positioned. Then, thecleaner body 11 is slightly inclined with respect to the line perpendicular to the floor in the upright mode, so that the center of gravity of thecleaner body 11 is switched from the rear of thesuction port assembly 20 to the front, thus allowing thecleaner body 11 to be securely placed on thesuction port assembly 20 on the upper side. This structure prevents the cleanermain body 11 from turning on the floor when the vacuum cleaner is not performing a cleaning operation, and prevents the cleanermain body 11 from being damaged by an external force such as vibration applied to the cleaner. An example of a latch member for snap engagement provided on the lower end of the cleanermain body 11 and the upper end of thesuction port assembly 20 for fixing the cleanermain body 11 in place may also be employed.

连接管23b与形成于吸入口组件20内部的流入通道20b流体连通。因此连接管23b起到引导通道的作用，该引导通道将来自吸入通道20b的灰尘和空气导向延伸管17。当真空吸尘器处于直立模式时，吸尘器主体11和延伸管17可以以预定角度向用户倾斜，以允许用户更方便地使用吸尘器。Theconnection pipe 23 b is in fluid communication with theinflow passage 20 b formed inside thesuction port assembly 20 . Theconnection pipe 23 b thus functions as a guide passage that guides the dust and air from thesuction passage 20 b to theextension pipe 17 . When the vacuum cleaner is in the upright mode, the cleanermain body 11 and theextension pipe 17 may be inclined toward the user at a predetermined angle to allow the user to use the cleaner more conveniently.

以下将详细描述根据本发明第一典型实施例的、处于直立模式和罐式模式下的真空吸尘器操作。Operations of the vacuum cleaner in the upright mode and the canister mode according to the first exemplary embodiment of the present invention will be described in detail below.

图2主要示出处于直立模式的真空吸尘器，其中，延伸管17与锁扣一接合部件14a，14b锁扣接合，并且延伸管17的一端与铰接部件23的连接管23b相接合。FIG. 2 mainly shows the vacuum cleaner in the upright mode, wherein theextension pipe 17 is snap-engaged with the snap-engagement parts 14a, 14b and one end of theextension pipe 17 is engaged with the connectingpipe 23b of thehinge part 23 .

在直立模式下，清洁单元10设置在吸入口组件的上部中，通过延伸管17与吸入口组件20流体连通。In the upright mode, thecleaning unit 10 is disposed in the upper portion of the suction port assembly, and is in fluid communication with thesuction port assembly 20 through theextension pipe 17 .

由于为电机12a供电并且电机12a产生吸力，来自待清洁表面的室内灰尘和空气通过吸入口20，然后通过吸入通道20b被吸入。As themotor 12a is powered and themotor 12a generates suction, house dust and air from the surface to be cleaned passes through thesuction port 20 and then is sucked through thesuction channel 20b.

带有灰尘的空气在流入到灰尘分离单元12b中之前，依次通过连接管23b，延伸管17，操作手柄15以及软管13。灰尘在灰尘分离单元12b内部与空气分离，并被收集到设在灰尘分离单元12内部的灰尘收集区域(未示出)中。清洁后的空气穿过电机12a，并通过形成于吸尘器主体11的区域上的排放孔(未示出)排放至外部，该吸尘器主体11与电机12a相邻。The dust-laden air passes through theconnection pipe 23b, theextension pipe 17, the operatinghandle 15 and thehose 13 in sequence before flowing into thedust separation unit 12b. The dust is separated from the air inside thedust separation unit 12b and collected into a dust collection area (not shown) provided inside the dust separation unit 12 . The cleaned air passes through themotor 12a, and is discharged to the outside through a discharge hole (not shown) formed in the area of the cleanermain body 11 adjacent to themotor 12a.

用户可将吸尘器切换成在罐式模式下操作，以清洁某些对于相对较大和较重的立式吸尘器来说难以覆盖的地方。Users can switch the vacuum cleaner to operate in canister mode to clean certain spots that are difficult for relatively large and heavy upright vacuum cleaners.

因此，如图2所示，用户使延伸管17从铰接部件23的连接管23b分离，并因此使清洁单元10从吸入口组件20完全分离。如图3所示，然后用户使延伸管17从吸尘器主体11的锁扣-接合部件14a，14b分离，然后，需要时，将比吸入口组件20相对较小且较轻的附件喷嘴30连接至延伸管17的一端。Therefore, as shown in FIG. 2 , the user detaches theextension pipe 17 from theconnection pipe 23 b of thehinge part 23 , and thus completely detaches thecleaning unit 10 from thesuction port assembly 20 . As shown in Figure 3, the user then detaches theextension tube 17 from the snap-engagement parts 14a, 14b of thecleaner body 11 and then, if desired, attaches theaccessory nozzle 30, which is relatively smaller and lighter than thesuction inlet assembly 20, to the One end ofextension tube 17.

切换成罐式吸尘器的真空吸尘器开始通过附件喷嘴30利用吸力从吸入口组件20周围吸入空气和灰尘，随着为吸入电机12a供电而开始驱动时产生该吸力。The vacuum cleaner switched to a canister cleaner starts to suck in air and dust from around thesuction port assembly 20 through theattachment nozzle 30 with the suction force generated as thesuction motor 12a starts to be driven with power.

带有灰尘的空气进入附件喷嘴30，并依次通过延伸管17，操作手柄组件15，以及软管13，并进入灰尘从空气中分离的灰尘分离单元12b。然后，灰尘在设置在灰尘分离单元12b内部的灰尘收集区域(未示出)中被收集，并且净化的空气通过吸入电机12a，并然后通过形成于部分的吸尘器主体11中的排放孔(未示出)排放至外部，该吸尘器主体11与吸入电机12a相邻The dust-laden air enters theattachment nozzle 30, passes through theextension pipe 17, the operatinghandle assembly 15, and thehose 13 in sequence, and enters thedust separation unit 12b where the dust is separated from the air. Then, the dust is collected in a dust collection area (not shown) provided inside thedust separation unit 12b, and the purified air passes through thesuction motor 12a, and then passes through a discharge hole (not shown) formed in part of the cleanermain body 11. out) to the outside, the vacuum cleanermain body 11 is adjacent to thesuction motor 12a

如上所述，由于延伸管17可在直立模式下作为框架使用，避免了用于支撑位于吸入口组件20之上的吸尘器主体11的分离框架的需要，因此吸入口组件20可以更简单设计制造，As mentioned above, since theextension pipe 17 can be used as a frame in the upright mode, avoiding the need of a separate frame for supporting thecleaner body 11 above thesuction port assembly 20, thesuction port assembly 20 can be designed and manufactured more simply,

由于吸尘器主体11被制成在直立模式下以预定角度(θ)围绕吸入口组件20旋转，从而允许用户更方便操作吸入口组件20，因此使真空吸尘器更加便于使用。Since the cleanermain body 11 is made to rotate around thesuction port assembly 20 at a predetermined angle (θ) in the upright mode, thereby allowing a user to more conveniently manipulate thesuction port assembly 20 , the vacuum cleaner is more convenient to use.

根据本发明典型实施例的真空吸尘器还通过简单的两个步骤操作易于在立式和罐式模式之间变换，该两个步骤的操作包括将延伸管17接合至连接管23b或从连接管23b分离，以及将吸尘器主体11接合至吸入口组件20或从吸入口组件20分离。Vacuum cleaners according to exemplary embodiments of the present invention are also easy to change between upright and canister modes by a simple two-step operation comprising engaging theextension tube 17 to or from the connectingtube 23b detaching, and coupling the cleanermain body 11 to thesuction port assembly 20 or separating from thesuction port assembly 20 .

以下将描述根据本发明第二典型实施例的真空吸尘器处于罐式模式和直立模式下的操作。Operations of a vacuum cleaner in a canister mode and an upright mode according to a second exemplary embodiment of the present invention will be described below.

参照图11，当真空吸尘器在直立模式操作下时，吸尘器主体200的下部锁定在支撑部件120(图1)中。延伸管320的一端穿过第二延伸管支撑部件243(图2)，并且操作手柄组件300插入操作手柄组件400的后壳体413中。Referring to FIG. 11 , when the vacuum cleaner is operated in the upright mode, the lower portion of thecleaner body 200 is locked in the support member 120 ( FIG. 1 ). One end of theextension pipe 320 passes through the second extension pipe support part 243 ( FIG. 2 ), and theoperation handle assembly 300 is inserted into therear case 413 of theoperation handle assembly 400 .

该插入包括将操作手柄组件300的突出对307和309插入到引导孔对414e和414f中，和使将操作手柄组件300的突出301压住插销434f的倾斜表面434g和434h，插销434f突出通过后壳体413的引导孔414d，并被定位于后壳体413的孔414c中。The insertion includes inserting the pair of protrusions 307 and 309 of theoperating handle assembly 300 into the pair ofguide holes 414e and 414f, and pressing the protrusions 301 of theoperating handle assembly 300 against theinclined surfaces 434g and 434h of thelatch 434f that protrudes through the back. Theguide hole 414d of thehousing 413 is positioned in thehole 414c of therear housing 413 .

通过弹性件439被横向弹性支撑的插销434f以预定角度沿引导孔414d转动，且然后，当突出301插入到孔414c中时，沿引导孔414d回转，以被插入突出301的锁定孔303中。Thelatch 434f laterally elastically supported by theelastic member 439 rotates along theguide hole 414d at a predetermined angle, and then, when the protrusion 301 is inserted into thehole 414c, turns along theguide hole 414d to be inserted into the locking hole 303 of the protrusion 301 .

根据操作手柄组件300插入携带手柄组件400中的运动，延伸管320的一端插入延伸管容纳部件121的穿孔121a中。According to the motion of inserting theoperating handle assembly 300 into the carryinghandle assembly 400 , one end of theextension tube 320 is inserted into the throughhole 121 a of the extensiontube receiving part 121 .

然后，如图11所示，用户将操作手柄组件300举至其身高处，以使真空吸尘器沿地板方便地移动。以下将描述改变操作手柄组件300的高度的过程。Then, as shown in FIG. 11 , the user lifts theoperating handle assembly 300 to his height to conveniently move the vacuum cleaner along the floor. The process of changing the height of theoperating handle assembly 300 will be described below.

用户拉操作手柄组件300，以使延伸管320延伸。也就是说，用户沿按钮部件435的轴向竖直地按压按钮部件435，以操作锁定设备(未示出)释放滑杆420。The user pulls on theoperating handle assembly 300 to extend theextension tube 320 . That is, the user presses thebutton part 435 vertically in the axial direction of thebutton part 435 to operate the locking device (not shown) to release theslide bar 420 .

用户保持按压通过弹性构件439弹性支撑的按钮部件435，并拉操作手柄组件300，使得操作手柄组件300与携带手柄组件400一起，从吸尘器主体200上部被释放，其中携带手柄组件400与操作手柄组件300相接合。然后，当用户停止按压按钮部件435时，按钮部件435通过弹性构件439的返回力作用返回至原始位置。The user keeps pressing thebutton part 435 elastically supported by theelastic member 439, and pulls the operatinghandle assembly 300, so that the operatinghandle assembly 300 and the carryinghandle assembly 400 are released from the upper part of the vacuum cleanermain body 200, wherein the carryinghandle assembly 400 and theoperating handle assembly 300 engaged. Then, when the user stops pressing thebutton part 435 , thebutton part 435 returns to the original position by the returning force of theelastic member 439 .

结果，用户可以将真空吸尘器的操作手柄组件300举至身高处，并可将真空吸尘器作为立式真空吸尘器使用。As a result, the user can lift theoperating handle assembly 300 of the vacuum cleaner to a height and use the vacuum cleaner as an upright vacuum cleaner.

以下将参照图12描述真空吸尘器从直立模式切换至罐式模式的过程。The process of switching the vacuum cleaner from the upright mode to the canister mode will be described below with reference to FIG. 12 .

当用户以预定角度转动按钮部件435的旋转杆436a时，使旋转部件435的插销434f沿引导孔414d转动，并从锁定孔303分离。When the user rotates therotation lever 436 a of thebutton part 435 at a predetermined angle, thelatch 434 f of therotation part 435 is rotated along theguide hole 414 d and separated from the lock hole 303 .

用户使旋转杆436a保持在旋转位置中，并向上手拉操作手柄组件300，使得突出对307和309从引导孔对414e和414f中分离。在此过程中，当操作手柄组件300的突出301从414c分离时，插销434f沿引导孔414d运动，并返回至初始位置。The user holds therotation lever 436a in the rotation position and manually pulls the operatinghandle assembly 300 upward, disengaging the pair of protrusions 307 and 309 from the pair ofguide holes 414e and 414f. During this process, when the protrusion 301 of theoperating handle assembly 300 is separated from 414c, thelatch 434f moves along theguide hole 414d, and returns to the original position.

如上所述，用户可通过简单地旋转按钮部件435和拉或推操作手柄组件300将真空吸尘器从直立模式切换至罐式模式。As described above, the user can switch the vacuum cleaner from the upright mode to the canister mode by simply rotating thebutton member 435 and pulling or pushing the operatinghandle assembly 300 .

为收起真空吸尘器，参照图12，用户将操作手柄组件300锁定至携带手柄组件400，将延伸管320插入到延伸管支撑部件241和243中，将软管310插入到第一和第二管支撑部件245和247中，并推操作手柄组件300，以减小延伸管320的长度，并随后减小真空吸尘器的总体重量。To put away the vacuum cleaner, referring to FIG. 12, the user locks the operatinghandle assembly 300 to the carryinghandle assembly 400, inserts theextension tube 320 into the extensiontube support members 241 and 243, inserts thehose 310 into the first and secondtubes Support members 245 and 247, and push theoperating handle assembly 300 to reduce the length of theextension tube 320, and subsequently reduce the overall weight of the vacuum cleaner.

如在第一典型实施例中一样，由于吸入口组件100不需要用于支持吸尘器主体200的分离框架部件，因此可以实现简单的结构。As in the first exemplary embodiment, since thesuction port assembly 100 does not require a separate frame part for supporting the cleanermain body 200, a simple structure can be achieved.
