下面详细描述本发明的实施例,所述实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,仅用于解释本发明,而不能理解为对本发明的限制。The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are intended to be illustrative of the invention and are not to be construed as limiting.
下面参考图1-图5描述根据本发明实施例的吸尘器的具体结构。A specific structure of a vacuum cleaner according to an embodiment of the present invention will be described below with reference to Figs.
如图1、图3和图5所示,根据本发明实施例的吸尘器1000包括机身组件300和尘杯组件400,尘杯组件400可拆卸地连接在机身组件300的前侧。As shown in FIGS. 1, 3, and 5, a vacuum cleaner 1000 according to an embodiment of the present invention includes a fuselage assembly 300 and a dust cup assembly 400 that is detachably coupled to a front side of the fuselage assembly 300.
尘杯组件400包括尘杯体470和旋风筒480。尘杯体470内限定出尘杯腔471,尘杯体470上设有尘杯进风口472,尘杯体470内底部构成积灰腔473,尘杯体470的对应积灰腔473的部分外周壁向外凸出形成凸起。旋风筒480设在尘杯体470内,旋风筒480上设有对应尘杯进风口472设置的旋风进管481,旋风进管481沿进风方向呈螺旋延伸,旋风筒480的底部设有连通积灰腔473的落灰孔482。The dust cup assembly 400 includes a dust cup body 470 and a cyclone cylinder 480. The dust cup body 470 defines a dust cup cavity 471, and the dust cup body 470 is provided with a dust cup air inlet 472. The bottom of the dust cup body 470 constitutes a dust collecting chamber 473, and a part of the outer circumference of the corresponding dust collecting chamber 473 of the dust cup body 470 The wall protrudes outward to form a projection. The cyclone cylinder 480 is disposed in the dust cup body 470. The cyclone cylinder 480 is provided with a cyclone inlet pipe 481 corresponding to the dust cup air inlet 472. The cyclone inlet pipe 481 extends spirally along the air inlet direction, and the bottom of the cyclone cylinder 480 is connected. The ash hole 482 of the dust collecting chamber 473.
可以理解的是,当吸尘器1000正常工作时,气流带着灰尘进入尘杯进风口472,经过旋风进管481进入旋风筒480,由于在正常状态下,旋风筒480处于倾斜状态,且旋风进管481沿进风方向呈螺旋延伸,当气流进入到圆形筒壁时,气流会迅速带着灰尘旋转同时上升,由于气流中大颗粒物重量较重,会由于自重最终大颗粒灰尘落入尘杯,实现气尘分离,由此可以提高尘杯的气尘分离效率。It can be understood that when the vacuum cleaner 1000 is working normally, the airflow enters the dust cup air inlet 472 with dust, and enters the cyclone cylinder 480 through the cyclone inlet pipe 481. Since the cyclone cylinder 480 is in a tilt state under normal conditions, the cyclone tube is circulated. The 481 spirals in the direction of the air inlet. When the airflow enters the circular cylinder wall, the airflow will rapidly rotate with the dust and rise at the same time. Due to the heavy weight of the large particles in the airflow, the large particles of dust will fall into the dust cup due to the self-weight. The separation of air and dust is achieved, thereby improving the dust separation efficiency of the dust cup.
此外,下落的灰尘将从落灰孔482进入尘杯的积灰腔473,由于尘杯体470的对应 积灰腔473的部分外周壁向外凸出形成凸起。因此,当部分旋风旋到尘杯底部时,该凸起部分可以使旋风气流紊乱,最终使得积灰腔473里的灰尘不会被再次旋起而留在尘杯中,这样避免了积灰腔473里的灰尘被二次旋起导致已收集的灰尘被二次过滤的现象发生,从而提高了尘杯组件400的过滤效率。Further, the falling dust will enter the dust collecting chamber 473 of the dust cup from the falling hole 482, and a part of the outer peripheral wall of the corresponding dust collecting chamber 473 of the dust cup body 470 protrudes outward to form a projection. Therefore, when a part of the cyclone is screwed to the bottom of the dust cup, the convex portion can turbulence of the cyclone flow, and finally the dust in the dust collecting chamber 473 is not rotated again and remains in the dust cup, thus avoiding the dust collecting chamber. The dust in the 473 is repeatedly squished to cause the collected dust to be secondary filtered, thereby improving the filtration efficiency of the dust cup assembly 400.
根据本发明实施例的吸尘器1000,在尘杯组件400中设置有旋风进管481成螺旋状的旋风筒480实现了高效率的气尘分离,于此同时,尘杯体470的对应积灰腔473的部分外周壁向外凸出形成凸起,避免了积灰腔473里的灰尘被二次旋起导致已收集的灰尘被二次过滤的现象发生,从而提高了尘杯组件的过滤效率。According to the vacuum cleaner 1000 of the embodiment of the present invention, the cyclone cylinder 480 in which the cyclone inlet pipe 481 is spirally disposed in the dust cup assembly 400 realizes high-efficiency air dust separation, and at the same time, the corresponding dust collecting chamber of the dust cup body 470 A part of the outer peripheral wall of the 473 protrudes outward to form a protrusion, which prevents the dust in the dust collecting chamber 473 from being secondarily swirled, so that the collected dust is secondary filtered, thereby improving the filtering efficiency of the dust cup assembly.
在一些实施例中,如图3所示,旋风筒480的底壁形成为平面。可以理解的是,在正常状态下,旋风筒480处于倾斜状态,旋风筒480的底壁形成为平面,更有利于大颗粒灰尘下滑至落灰孔482,并从落灰孔482进入积灰腔473。In some embodiments, as shown in FIG. 3, the bottom wall of the cyclone cylinder 480 is formed as a flat surface. It can be understood that, in the normal state, the cyclone cylinder 480 is in an inclined state, and the bottom wall of the cyclone cylinder 480 is formed into a plane, which is more favorable for the large particle dust to slide down to the ash hole 482 and enter the ash chamber from the ash hole 482. 473.
在一些实施例中,如图4所示,旋风筒480的外周壁上设有旋风出口483。可以理解的是,当旋风筒480正常工作时,大体积的垃圾将从旋风出口483被甩出,这样可以有效地解决旋风筒480被大体积垃圾阻塞的问题,减少了用户的倒灰次数。In some embodiments, as shown in FIG. 4, a cyclone outlet 483 is provided on the outer peripheral wall of the cyclone cylinder 480. It can be understood that when the cyclone 480 is working normally, a large volume of garbage will be taken out from the cyclone outlet 483, which can effectively solve the problem that the cyclone 480 is blocked by a large volume of garbage, and reduces the number of times of dusting by the user.
具体地,如图4所示,在进风方向上旋风出口483与旋风进管481之间的夹角大于180度。由此,可以更好地将大体积垃圾从旋风出口483被甩出。Specifically, as shown in FIG. 4, the angle between the cyclone outlet 483 and the cyclone inlet 481 is greater than 180 degrees in the air inlet direction. Thereby, it is possible to better remove large-volume garbage from the cyclone outlet 483.
在一些实施例中,如图2所示,在由中心到外周的方向上,旋风进管481的管截面面积逐渐增大。In some embodiments, as shown in FIG. 2, the cross-sectional area of the vortex inlet tube 481 is gradually increased in the direction from the center to the outer circumference.
在一些实施例中,如图5所示,机身组件300上设有扣件310,尘杯组件400可拆卸地连接在机身组件300的前侧。尘杯组件400包括尘杯手柄体420、尘杯手柄盖430、尘杯释放按钮440、按钮复位弹性件450和装配螺钉460。尘杯手柄体420位于机身组件300的前侧,尘杯手柄体420上设有装配孔422。尘杯手柄盖430盖合在尘杯手柄体420上,尘杯手柄盖430与尘杯手柄体420之间限定出手柄内腔,尘杯手柄盖430上设有导向螺柱431和按钮出孔432,导向螺柱431上设有正对装配孔422的装配螺纹孔4311。尘杯释放按钮440可滑动地设在手柄内腔内,尘杯释放按钮440的一部分配合在按钮出孔432内,尘杯释放按钮440上设有卡件441,卡件441伸出手柄内腔且与扣件310相扣合,卡件441上设有外套在导向螺柱431上的导向孔442。按钮复位弹性件450连接在尘杯释放按钮440和手柄内腔的内壁之间。装配螺钉460穿过装配孔422且连接在装配螺纹孔4311内,导向螺柱431的延伸方向与卡件441的扣合方向相一致。In some embodiments, as shown in FIG. 5, the fuselage assembly 300 is provided with a fastener 310 that is detachably coupled to the front side of the fuselage assembly 300. The dust cup assembly 400 includes a dust cup handle body 420, a dust cup handle cover 430, a dust cup release button 440, a button reset elastic member 450, and an assembly screw 460. The dust cup handle body 420 is located on the front side of the body assembly 300, and the dust cup handle body 420 is provided with a mounting hole 422. The dust cup handle cover 430 is closed on the dust cup handle body 420. The dust cup handle cover 430 and the dust cup handle body 420 define a handle inner cavity. The dust cup handle cover 430 is provided with a guiding stud 431 and a button exit hole. 432. The guiding stud 431 is provided with a fitting threaded hole 4311 facing the mounting hole 422. The dust cup release button 440 is slidably disposed in the inner cavity of the handle, a part of the dust cup release button 440 is fitted in the button outlet hole 432, and the dust cup release button 440 is provided with a card member 441, and the card member 441 extends out of the handle cavity. And engaging with the fastener 310, the card member 441 is provided with a guiding hole 442 on the guiding stud 431. The button return elastic member 450 is coupled between the dust cup release button 440 and the inner wall of the handle lumen. The assembly screw 460 passes through the fitting hole 422 and is connected in the fitting screw hole 4311, and the extending direction of the guide stud 431 coincides with the fastening direction of the card member 441.
可以理解的是,尘杯组件400上的卡件441与机身组件300上的扣件310相配合,可将尘杯组件400锁死在机身组件300上。如图4所示,当按下尘杯组件400上的尘杯 释放按钮440时,卡件441从扣件310中脱离出来,此时可将尘杯组件400从机身组件300上拆下。由此,尘杯组件400和机身组件300解锁的操作非常简单,用户可以方便快捷地将尘杯组件400和机身组件300解锁。It will be appreciated that the clip 441 on the dust cup assembly 400 cooperates with the fastener 310 on the body assembly 300 to lock the dust cup assembly 400 to the body assembly 300. As shown in Figure 4, when the dust cup release button 440 on the dust cup assembly 400 is pressed, the card member 441 is disengaged from the fastener 310, at which point the dust cup assembly 400 can be removed from the body assembly 300. Thus, the operation of unlocking the dust cup assembly 400 and the body assembly 300 is very simple, and the user can quickly and easily unlock the dust cup assembly 400 and the body assembly 300.
可以理解的是,卡件441上设有外套在导向螺柱431上的导向孔442,且导向柱的延伸方向与卡件441的扣合方向一致,因此,导向螺柱431可以对卡件441的活动起到导向作用,避免由于用户按压尘杯释放按钮440时,卡件441发生歪斜导致卡件441和扣件310出现“卡死”现象。It can be understood that the card member 441 is provided with a guiding hole 442 on the guiding stud 431, and the extending direction of the guiding post is consistent with the fastening direction of the card member 441. Therefore, the guiding stud 431 can be opposite to the card member 441. The activity plays a guiding role to prevent the card member 441 and the fastener 310 from being "snapped" due to the skew of the card member 441 when the user presses the dust cup release button 440.
此外,由于导向螺柱431设置尘杯手柄盖430上,尘杯手柄体420上设有正对导向螺柱431的装配孔422,尘杯释放按钮440上的卡件441上设有外套在导向螺柱431上的导向孔442,且导向螺柱431上设有装配螺纹孔4311,因此,在安装过程中,导向螺柱431穿过尘杯释放按钮440后正对装配孔422设置,再将装配螺钉460穿过装配孔422与导向螺柱431上的装配螺纹孔4311配,由此实现尘杯手柄盖430、尘杯手柄体420和尘杯释放按钮440的连接。也就是说,导向螺柱431能够起到连接尘杯手柄盖430、尘杯手柄体420和尘杯释放按钮440作用。In addition, since the guide stud 431 is disposed on the dust cup handle cover 430, the dust cup handle body 420 is provided with an assembly hole 422 facing the guide stud 431, and the card member 441 on the dust cup release button 440 is provided with a jacket on the guide. a guiding hole 442 on the stud 431, and the guiding stud 431 is provided with a fitting threaded hole 4311.
