Description
本發明，是有關於吸塵器的吸口體及使用其的吸塵器。 The present invention relates to a mouthpiece of a vacuum cleaner and a vacuum cleaner using the same.
習知技術的吸塵器的吸入具(吸口體)，是在具有吸入口的吸入具本體(吸口本體)，安裝了可在被掃除面上自由轉動的起毛布滾子體，且具備制動手段，可限制前述起毛布滾子體的旋轉方向的一方向的動作，但讓旋轉方向的相反方向的動作成為自由(例如專利文獻1參照)。 The suction device (suction body) of the vacuum cleaner of the prior art is a riser body (sucking body) having a suction port, and is provided with a raised fabric roller body that is freely rotatable on the surface to be cleaned, and has a braking means. The operation in one direction of the rotation direction of the raised fabric roller body is restricted, but the operation in the opposite direction to the rotation direction is free (for example, refer to Patent Document 1).
[專利文獻1]日本專利第3268514號公報 [Patent Document 1] Japanese Patent No. 3268514
但是專利文獻1的制動手段，因為是由：形成於吸入具本體(吸口本體)的起毛布滾子體周面及相面對的壁面之間的楔狀空間；及被配置於該楔狀空間內位於前述起毛布滾子體周面及前述壁面之間，在該起毛布滾子體的旋轉方向的一方向的動作時嵌入該楔狀空間內的後側來限制該起毛布滾子體的動作的制動輪所構成，所以構造複雜。且藉由沙塵等的侵入和線纏結使制動輪的動作被妨害，可能使起毛布滾子體的制動功能減損。因此在吸入具(吸口體)後退時，起毛布滾子體的旋轉被限制，吸入具(吸口體)後方的塵埃無法被集塵，在吸入具(吸口體)前進時起毛布滾子體會旋轉，而使朝吸入口被吸引的塵埃具有朝起毛布滾子體的後方掃出的可能。 However, the braking means of Patent Document 1 is formed by a wedge-shaped space formed between the peripheral surface of the raised fabric roller body and the facing wall surface of the suction device main body (suction port body); and is disposed in the wedge-shaped space. The inner surface of the raised fabric roller body and the wall surface are inserted into the rear side of the wedge-shaped space during the movement of the raised fabric roller in one direction to restrict the riser roller body. The brake wheel is constructed so that the structure is complicated. Further, the operation of the brake wheel is impaired by the intrusion of sand dust or the like and the entanglement of the wire, and the braking function of the felt roller body may be impaired. Therefore, when the suction tool (suction body) retreats, the rotation of the raising cloth roller body is restricted, and the dust behind the suction tool (suction body) cannot be collected, and the lifting cloth roller body rotates when the suction tool (suction body) advances. Therefore, the dust attracted to the suction port may be swept out toward the rear of the pile roller body.
本發明的目的是提供一種吸塵器的吸口體及使用其的吸塵器，藉由由簡單的構成，限制起毛布滾子體的旋轉方向的一方向的動作，容許旋轉方向的相反方向的動作，來提高吸口體後退時的集塵性能。 An object of the present invention is to provide a nozzle body of a vacuum cleaner and a vacuum cleaner using the same, which can restrict the movement in one direction of the rotation direction of the pile roller body by a simple configuration, and allow the movement in the opposite direction of the rotation direction to improve Dust collection performance when the mouthpiece is retracted.
本發明，其特徵為，具備：設有與清掃面大致平行的旋轉軸的第1旋轉清掃體、及將前述第1旋轉清掃體支撐的吸入室、及在前述第1旋轉清掃體的後方具有與前述旋轉軸平行的軸並與前述清掃面接觸的第2旋轉清掃體，在該第2旋轉清掃體的表面中，設置刷毛體或是彈 性體，該刷毛體或是彈性體，是設成與該吸口體的一部分接觸，在該吸口體的後退時容許前述第2旋轉清掃體的旋轉動作，且在前進時限制前述第2旋轉清掃體的旋轉動作的方式，朝圓周方向傾斜地設置。 The present invention is characterized in that the first rotating cleaning body including a rotating shaft substantially parallel to the cleaning surface, and a suction chamber for supporting the first rotating cleaning body and a rear side of the first rotating cleaning body are provided. a second rotating cleaning body that is in contact with the cleaning surface on the axis parallel to the rotating shaft, and a brush body or a bullet is provided on the surface of the second rotating cleaning body The body, the brush body or the elastic body is placed in contact with a part of the mouthpiece, and allows the rotation of the second rotating cleaning body when the mouthpiece is retracted, and restricts the second rotation cleaning during forward movement. The manner of the rotation of the body is obliquely arranged in the circumferential direction.
依據本發明的話，可提供一種吸塵器的吸口體及使用其的吸塵器，藉由由簡單的構成，限制起毛布滾子體的旋轉方向的一方向的動作，容許旋轉方向的相反方向的動作，來提高吸口體後退時的集塵性能。 According to the present invention, it is possible to provide a nozzle body of a vacuum cleaner and a vacuum cleaner using the same, which can restrict the movement in one direction of the rotation direction of the pile roller body by a simple configuration, and allow the operation in the opposite direction of the rotation direction.

For example, one second rotating cleaning element 30 is composed of a diameter of about one-half of the diameter of the first rotating cleaning element 20 and a length of substantially one third of the length of the first rotating cleaning element 20 in the axial direction. The suction port body 11 may be provided on both sides of the flow path R that holds the two second rotating cleaning elements 30.
且各第2旋轉清掃體30，是具有與第1旋轉 清掃體20的旋轉軸21平行的軸30a。在此軸30a的外周的配管體30e(第6圖參照)的外側由微細纖維形成的切斷絨頭狀的刷毛體(起毛布)30b是對於配管體30e的旋轉軸方向呈螺旋狀地捲取，此刷毛體(起毛布)30b的微細纖維是對於配管體30e朝圓周方向傾斜。此刷毛體(起毛布)30b，是設成與吸口體6的一部分接觸，在吸口體6的後退時容許第2旋轉清掃體30的旋轉動作，且在前進時限制前述第2旋轉清掃體30的旋轉動作的方式朝圓周方向傾斜地設置。在配管體30e的兩端面中，固定有支架30c、30d。且，此支架30c、30d，是將捲附的刷毛體(起毛布)30b的端部推壓防止剝離，並且兼具軸30a的軸承。軸30a及配管體30e因為是大致同心圓地具有間隙，由此配管體30e及刷毛體(起毛布)30b，是可轉動地被支撐在軸30a。如此，不是由電動機將第2旋轉清掃體30驅動，而是透過軸30a被支撐於吸口本體11，藉由與地面的接觸被旋轉驅動，就可以將第2旋轉清掃體30的構成簡略化。進一步，因為刷毛體(起毛布)30b的微細纖維是容許一方向的旋轉動作限制另一方向的旋轉動作的方式對於配管體30e朝圓周方向傾斜，所以在吸口體6的組裝時使不會誤朝相反方向安裝的方式，使支架30c及30d使用不同的顏色、改變形狀等，對應吸口本體11中的支架30c及30d的部分也藉由可對應其改變顏色和形狀，就可了解左右的安裝方向，不會誤安裝。 And each of the second rotary cleaning bodies 30 has a first rotation The shaft 30a of the cleaning body 20 in which the rotating shaft 21 is parallel. The cut pile-shaped bristle body (hairing cloth) 30b formed of fine fibers on the outer side of the pipe body 30e (refer to FIG. 6) on the outer circumference of the shaft 30a is spirally wound in the direction of the rotation axis of the pipe body 30e. The fine fibers of the bristle body (hairing cloth) 30b are inclined toward the circumferential direction of the pipe body 30e. The brush body (hair raising cloth) 30b is placed in contact with a part of the mouthpiece body 6, and allows the rotation of the second rotating cleaning body 30 when the mouthpiece body 6 is retracted, and restricts the second rotating cleaning body 30 during advancement. The manner of the rotating motion is set obliquely in the circumferential direction. Brackets 30c and 30d are fixed to both end faces of the pipe body 30e. Further, the holders 30c and 30d are bearings for pressing the end portion of the wound bristle body (hairing cloth) 30b to prevent peeling and also having the shaft 30a. Since the shaft 30a and the pipe body 30e have a gap substantially concentrically, the pipe body 30e and the bristle body (hairing cloth) 30b are rotatably supported by the shaft 30a. In this manner, the second rotating cleaning body 30 is not driven by the electric motor, but the transmission shaft 30a is supported by the suction body 11 and is rotationally driven by contact with the ground, whereby the configuration of the second rotary cleaning body 30 can be simplified. Further, since the fine fibers of the brush body (hairing cloth) 30b allow the rotation operation in the other direction to restrict the rotation operation in the other direction, the pipe body 30e is inclined in the circumferential direction, so that the assembly of the mouthpiece body 6 is not mistaken. Mounting in the opposite direction allows the brackets 30c and 30d to use different colors, shape changes, etc., and the portions corresponding to the brackets 30c and 30d in the mouthpiece body 11 can also be understood by changing the color and shape. Direction, will not be installed by mistake.
且包含支架30c及30d的第2旋轉清掃體30 的左右寬度，是比將此第2旋轉清掃體30安裝的收納室的寬度L1更短地構成。因此第2旋轉清掃體30是在左右具有間隙，可以沿著軸30a左右移動此間隙分。藉此，可以防止在清掃時地面的線屑和髪的毛等的細長的塵埃捲附在軸30a，若即使捲附在軸30a，也可以容易地去除。 And the second rotary cleaning body 30 including the brackets 30c and 30d The left and right widths are configured to be shorter than the width L1 of the storage chamber to which the second rotary cleaning body 30 is attached. Therefore, the second rotating cleaning body 30 has a gap on the left and right sides, and can move the gap portion to the right and left along the shaft 30a. Thereby, it is possible to prevent the elongate dust such as the lint on the floor and the bristles from being blown on the shaft 30a during the cleaning, and it can be easily removed even if it is wound around the shaft 30a.
又，在吸口殼10中，在吸口殼10的連結部12的下面設有毛刷驅動開關16，在毛刷驅動開關16的後方(連結部12的後端)設有車輪17。 Further, in the mouthpiece casing 10, a brush drive switch 16 is provided on the lower surface of the joint portion 12 of the mouthpiece casing 10, and a wheel 17 is provided behind the brush drive switch 16 (the rear end of the joint portion 12).
毛刷驅動開關16，是檢出吸口體6的下面是否與清掃面接觸的開關。毛刷驅動開關16，是具備車輪16a，此車輪16a是藉由彈簧等的推迫手段時常從吸口殼10(連結部12)的下面突出的方式被設置。且，被檢出車輪16a躥出未與地面接觸時，是藉由後述電路基板50(控制基板)停止電動機40的驅動。且，被檢出車輪16a被壓入並與地面接觸時，是藉由電路基板50使電動機40被驅動。 The brush drive switch 16 is a switch that detects whether or not the lower surface of the mouthpiece body 6 is in contact with the cleaning surface. The brush drive switch 16 is provided with a wheel 16a which is provided so as to protrude from the lower surface of the mouthpiece casing 10 (connection portion 12) by a pressing means such as a spring. When the detected wheel 16a is not in contact with the ground, the driving of the motor 40 is stopped by the circuit board 50 (control substrate) which will be described later. Further, when the detected wheel 16a is pressed into contact with the ground, the motor 40 is driven by the circuit board 50.
車輪17，是承受由操作管4***作的前後動和旋轉操作的應力使吸口體6的底面與清掃面密合，由此具有提高吸口體6的操作性能的角色。 The wheel 17 receives the stress of the forward and backward movement and the rotational operation operated by the operation tube 4, and the bottom surface of the mouthpiece 6 is brought into close contact with the cleaning surface, thereby having the function of improving the operability of the mouthpiece 6.
第4圖，是顯示取下吸口體6的上殼11B的狀態的俯視圖。 Fig. 4 is a plan view showing a state in which the upper case 11B of the mouthpiece body 6 is removed.
如第4圖所示，吸口體6，是在第1旋轉清掃體20及一對的第2旋轉清掃體30的上方，具備將第1旋轉清掃體20驅動的電動機40及將電動機40控制的電路 基板50。 As shown in FIG. 4, the mouthpiece 6 is provided above the first rotary cleaning body 20 and the pair of second rotary cleaning bodies 30, and includes a motor 40 that drives the first rotary cleaning element 20 and controls the motor 40.

電動機40，是被安裝於吸口本體11的長度方向的一端側。且，電動機40，其輸出軸40a(第5圖參照)是與吸口本體11的長度方向平行地配置。且，電動機40的輸出軸40a，是朝向長度方向的一端側延伸，在吸口本體11內的一端部(圖示右側的端部)，透過附齒皮帶40b與第1旋轉清掃體20的旋轉軸21(第5圖參照)連結。 The motor 40 is attached to one end side in the longitudinal direction of the mouthpiece body 11. Further, the motor 40 has its output shaft 40a (refer to FIG. 5) disposed in parallel with the longitudinal direction of the mouthpiece body 11. The output shaft 40a of the motor 40 extends toward the one end side in the longitudinal direction, and the one end portion (the end portion on the right side in the drawing) in the mouthpiece body 11 passes through the toothed belt 40b and the rotation shaft of the first rotary cleaning body 20. 21 (refer to Figure 5) link.
蓋構件43，是由具有合成橡膠等的彈力性的絕緣構件形成，因為利用此蓋構件43的彈力性使電動機40的一端側被支撐在收容室Q1，所以電動機40的振動不易傳到吸口殼10。 The cover member 43 is formed of an elastic insulating member having a synthetic rubber or the like. Since the one end side of the motor 40 is supported by the accommodating chamber Q1 by the elastic force of the cover member 43, the vibration of the motor 40 is not easily transmitted to the suction case. 10.
電路基板50，是被安裝於吸口本體11的長度方向的另一端側。且，電路基板50，是由其長邊朝向長度方向的方式配置的長方形狀的基板所構成，貼裝面50a是朝向垂直方向上方的方式被配置於吸口本體11內。又，貼裝面50a，並不一定要限定於朝向垂直方向上方者，對於水平方向傾斜也可以，朝向前後方向(縱方向)也可以。 The circuit board 50 is attached to the other end side of the nozzle body 11 in the longitudinal direction. Further, the circuit board 50 is formed of a rectangular substrate whose long sides are arranged in the longitudinal direction, and the mounting surface 50a is disposed in the nozzle body 11 so as to face upward in the vertical direction. Moreover, the mounting surface 50a is not necessarily limited to the upper side in the vertical direction, and may be inclined in the horizontal direction, and may be oriented in the front-rear direction (longitudinal direction).
第5圖，是第2圖的A-A剖面圖。 Fig. 5 is a cross-sectional view taken along line A-A of Fig. 2.
如第5圖所示，吸口殼10的吸口本體11，是具備：將第1旋轉清掃體20覆蓋的方式形成下部分的下殼11A、及被覆於下殼11A的上部的上殼11B。這些包含下殼11A和上殼11B的吸口殼10、及前述的吸口接頭13 的主要的零件，是輕量硬質的材料，例如，由ABS樹脂等的合成樹脂材料形成，使剛性提高。 As shown in Fig. 5, the mouthpiece body 11 of the mouthpiece casing 10 includes a lower casing 11A that forms a lower portion so as to cover the first rotary cleaning body 20, and an upper casing 11B that is coated on the upper portion of the lower casing 11A. These mouthpiece shells 10 including the lower case 11A and the upper case 11B, and the aforementioned mouthpiece joint 13 The main part is a lightweight hard material, for example, formed of a synthetic resin material such as ABS resin to improve rigidity.
下殼11A，是具有隔壁11c，將：配置有第1旋轉清掃體20的吸入室Q2、及收容有電動機40的收容室Q1區劃。隔壁11c，是具有：沿著第1旋轉清掃體20的表面形成的彎曲部11d、及沿著第2旋轉清掃體30的表面形成的彎曲部11e，彎曲部11d及彎曲部11e是連續形成。且，彎曲部11d，是在剖面視，延伸至第1旋轉清掃體20的大致前端部。彎曲部11e，是在剖面視，延伸至比第2旋轉清掃體30的後端部更後側且比軸30a更後側。 The lower case 11A has a partition wall 11c, and partitions the suction chamber Q2 in which the first rotary cleaning element 20 is disposed and the storage chamber Q1 in which the motor 40 is housed. The partition wall 11c has a curved portion 11d formed along the surface of the first rotary cleaning element 20 and a curved portion 11e formed along the surface of the second rotary cleaning body 30, and the curved portion 11d and the curved portion 11e are continuously formed. Further, the curved portion 11d extends to a substantially front end portion of the first rotary cleaning element 20 in a cross-sectional view. The curved portion 11e extends in a cross-sectional view and extends rearward of the rear end portion of the second rotating cleaning body 30 and further rearward than the shaft 30a.
上殼11B，是具有：與連結部12一體形成將電動機40及電路基板50(第4圖參照)的上部覆蓋的本體部11f、及與此本體部11f的外側重疊配置的蓋部11g。蓋部11g，是橫跨上殼11B的前部及左右兩端部地配置(第2圖參照)。在本實施例中，保險桿11a，是藉由由下殼11A及上殼11B(蓋部11g)挾持地被保持。 The upper case 11B has a main body portion 11f that covers the upper portion of the motor 40 and the circuit board 50 (refer to FIG. 4) integrally with the connecting portion 12, and a lid portion 11g that is disposed to overlap the outer side of the main body portion 11f. The lid portion 11g is disposed across the front portion and the left and right end portions of the upper casing 11B (see FIG. 2). In the present embodiment, the bumper 11a is held by the lower case 11A and the upper case 11B (the cover portion 11g).
第1旋轉清掃體20，其將毛刷20a、20b、20c呈螺旋狀保持的芯構件22是被外嵌於旋轉軸21。如此，藉由將毛刷20a、20b、20c呈螺旋狀地配置，第1旋轉清掃體20旋轉時，可以將毛刷20a、20b、20c連續與地面M(第8圖參照)接觸，可以抑制第1旋轉清掃體20的動作時的振動。 In the first rotating cleaning body 20, the core member 22 that holds the brushes 20a, 20b, and 20c in a spiral shape is externally fitted to the rotating shaft 21. By arranging the brushes 20a, 20b, and 20c in a spiral shape as described above, when the first rotary cleaning element 20 is rotated, the brushes 20a, 20b, and 20c can be continuously brought into contact with the floor surface M (refer to FIG. 8), and can be suppressed. The vibration of the first rotating cleaning body 20 during the operation.
第2旋轉清掃體30，是透過配管體30e使剖 面大致圓形狀的刷毛體(起毛布)30b安裝在軸30a，在吸口本體11中被配置於不與第1旋轉清掃體20接觸的位置。如此，在第2旋轉清掃體30不與第1旋轉清掃體20接觸的範圍，藉由使第1旋轉清掃體20及第2旋轉清掃體30最大限度接近，就成為可將吸口本體11的前後寬度D(第2圖參照)縮短，吸口體6成為可小型輕量化。 The second rotating cleaning body 30 is cut through the pipe body 30e. The brush body (pilling fabric) 30b having a substantially circular shape is attached to the shaft 30a, and is disposed at a position where the nozzle body 11 is not in contact with the first rotary cleaning body 20. In the range in which the second rotary cleaning body 30 is not in contact with the first rotary cleaning element 20, the first rotary cleaning element 20 and the second rotary cleaning element 30 are brought into close contact with each other, so that the front and rear of the suction nozzle body 11 can be obtained. The width D (refer to FIG. 2) is shortened, and the mouthpiece body 6 is made compact and lightweight.
電動機40的定子41，其橫剖面(與輸出軸40a垂直的剖面的輪廓，剖面為圓環形剖面)是大致細長形狀。定子41，是具備：一對的圓弧部41a、及將這些的圓弧部41a連接的一對的直線部41b。又，電動機40，不限定於大致細長形狀者，圓形狀者也可以。 The stator 41 of the motor 40 has a substantially elongated shape in a cross section (a contour of a cross section perpendicular to the output shaft 40a and a cross section in a circular cross section). The stator 41 includes a pair of arc portions 41a and a pair of straight portions 41b that connect the arc portions 41a. Further, the electric motor 40 is not limited to a substantially elongated shape, and may be a round shape.
且電動機40，是在收容室Q1中，直線部41b是成為對於垂直方向的軸Z1傾斜的姿勢，即一方的圓弧部41a是朝前上方且另一方的圓弧部41a是朝後下方的方式被收容。 In the storage chamber Q1, the linear portion 41b is inclined to the vertical axis Z1, that is, one arc portion 41a is facing forward and the other arc portion 41a is facing rearward and downward. The way is contained.
且電動機40，是在收容室Q1中，電動機40(定子41)的前端部41s，是位於比第1旋轉清掃體20的後端部20s更前方地配置。 In the storage chamber Q1, the motor 40 (the stator 41) has a distal end portion 41s that is disposed further forward than the rear end portion 20s of the first rotary cleaning element 20.
由此，可以將從第1旋轉清掃體20的後端部20s朝後方突出的電動機40的距離縮短，成為可將吸口本體11的前後寬度D(第2圖參照)縮短。 Thereby, the distance from the motor 40 which protrudes rearward from the rear end portion 20s of the first rotary cleaning body 20 can be shortened, and the front-back width D (refer to FIG. 2) of the mouthpiece main body 11 can be shortened.
且電動機40，是在收容室Q1中，電動機40(定子41)的下端部41t，是位於比第1旋轉清掃體20的上端部20t更垂直方向的下方地配置。由此，可以將從 第1旋轉清掃體20的上端部20t朝上方突出的電動機40的距離縮短，可以降低從吸口本體11的清掃面的高度(最大高度)。其結果，在沙發和床台等的高度較低的間隙可以容易將吸口本體11***。 In the accommodating chamber Q1, the lower end portion 41t of the motor 40 (stator 41) is disposed below the upper end portion 20t of the first rotating cleaning element 20 in the vertical direction. From this, you can The distance of the motor 40 that protrudes upward from the upper end portion 20t of the first rotary cleaning body 20 is shortened, and the height (maximum height) from the cleaning surface of the nozzle body 11 can be reduced. As a result, the mouthpiece body 11 can be easily inserted in a gap having a low height such as a sofa or a bed.
電樞44是可旋轉自如地被支撐在定子41的內部。在定子41的內周中，形成於場磁用的瓦狀的2個磁鐵45是在圓周方向隔有間隔地被固定。即，本實施例的電動機40，其槽的個數是7個，磁鐵45被設置2個的2極7槽的馬達。又，前述的槽的數量，不限定於7個，設成其他的個數(例如8個)也可以。 The armature 44 is rotatably supported inside the stator 41. In the inner circumference of the stator 41, the two magnets 45 formed in the shape of the field magnet are fixed at intervals in the circumferential direction. That is, in the electric motor 40 of the present embodiment, the number of slots is seven, and the magnet 45 is provided with two two-pole seven-slot motors. Further, the number of the above-described grooves is not limited to seven, and may be other numbers (for example, eight).
且吸口本體11的上殼11B，是在圓弧部41a的附近及直線部41b的附近，具有大致沿著圓弧部41a及直線部41b的形狀。且，吸口本體11的下殼11A，是在第1旋轉清掃體20的後方，具有從藉由下殼11A及上殼11B所構成的收容室Q1朝下方彎曲延伸的外圍壁11h。此外圍壁11h，是沿著第2旋轉清掃體30的曲面(表面)延伸，外圍壁11h的下端部11h1，是下降至第2旋轉清掃體30的軸30a的大致高度位置地延伸。 The upper casing 11B of the mouthpiece body 11 has a shape substantially along the arc portion 41a and the straight portion 41b in the vicinity of the circular arc portion 41a and in the vicinity of the linear portion 41b. The lower casing 11A of the mouthpiece body 11 has a peripheral wall 11h which is bent downward from the storage chamber Q1 including the lower casing 11A and the upper casing 11B, behind the first rotary cleaning body 20. Further, the surrounding wall 11h extends along the curved surface (surface) of the second rotary cleaning body 30, and the lower end portion 11h1 of the peripheral wall 11h extends to a substantially height position of the shaft 30a of the second rotary cleaning body 30.
第6圖，是第2圖的B-B剖面圖。 Fig. 6 is a cross-sectional view taken along line B-B of Fig. 2.
如第6圖所示，電路基板50，是在收容室Q1中，使貼裝面成為垂直方向(上下方向)向上地配置。即，電路基板50，不是配置於第1旋轉清掃體20的後方，而是配置於比第1旋轉清掃體20的上端部20t更上側。又，電路基板50，是藉由無圖示的定位手段和螺 固，使位置不偏離的方式被固定於吸口本體11內。且，在本實施例中，雖舉例說明了將電路基板50水平配置的情況的例，但是將電路基板50對於水平方向傾斜的狀態下配置的構成也可以，使電路基板50的貼裝面朝向前後方向的方式，將電路基板50立起的狀態下配置也可以。 As shown in FIG. 6, the circuit board 50 is placed in the storage chamber Q1 so that the mounting surface is oriented in the vertical direction (vertical direction). In other words, the circuit board 50 is disposed not on the rear side of the first rotating cleaning body 20 but on the upper side of the upper end portion 20t of the first rotating cleaning element 20. Moreover, the circuit board 50 is provided by a positioning means and a screw (not shown). The solid is fixed in the mouthpiece body 11 in such a manner that the position is not deviated. In the present embodiment, an example in which the circuit board 50 is horizontally arranged is exemplified, but the circuit board 50 may be disposed in a state of being inclined in the horizontal direction, and the mounting surface of the circuit board 50 may be oriented. The front-back direction may be arranged in a state in which the circuit board 50 is raised.
第2旋轉清掃體30，其在配管體30e的外側由微細纖維形成的切斷絨頭狀的刷毛體(起毛布)30b是呈螺旋狀地捲取，此刷毛體(起毛布)30b的微細纖維是對於配管體30e朝圓周方向傾斜。在配管體30e的兩端面中，固定有支架30c、30d。且，此支架30c、30d，是兼具：捲附的起毛布30b的端部的剝離防止、及軸30a的軸承。此起毛布30b的先端，是具有可與隔壁彎曲部11e的表面接觸的刷毛高度。因此，第2旋轉清掃體30旋轉時，在刷毛體(起毛布)30b及隔壁彎曲部11e的表面之間，摩擦阻力會發生，但是微細纖維因為是對於配管體30e朝圓周方向傾斜，所以在旋轉方向W2中，雖摩擦阻力小可自由地旋轉，但是在旋轉方向W3中，摩擦阻力大幾乎成為鎖定狀態。即，刷毛體(起毛布)30b，是設成與隔壁彎曲部11e接觸，在吸口體6的後退時容許朝第2旋轉清掃體30的旋轉方向W2的旋轉動作，且在前進時限制朝前述第2旋轉清掃體30的旋轉方向W3的旋轉動作的方式朝圓周方向傾斜地設置。 The second rotating cleaning body 30 is wound in a spiral shape by a cut pile-shaped bristle body (hairing cloth) 30b formed of fine fibers on the outer side of the pipe body 30e, and the fine body of the bristle body (hairing cloth) 30b The fiber is inclined in the circumferential direction with respect to the pipe body 30e. Brackets 30c and 30d are fixed to both end faces of the pipe body 30e. Further, the brackets 30c and 30d have both the peeling prevention of the end portion of the wound fleece fabric 30b and the bearing of the shaft 30a. The tip end of the raised fabric 30b has a bristle height which is in contact with the surface of the partition curved portion 11e. Therefore, when the second rotating cleaning body 30 rotates, frictional resistance occurs between the surface of the bristle body (hairing cloth) 30b and the partition wall bending portion 11e. However, since the fine fibers are inclined in the circumferential direction with respect to the pipe body 30e, In the rotation direction W2, although the frictional resistance is small, the rotation resistance can be freely rotated. However, in the rotation direction W3, the frictional resistance is almost the locked state. In other words, the brush body (hair raising cloth) 30b is provided in contact with the partition wall bending portion 11e, and is allowed to rotate in the rotation direction W2 of the second rotary cleaning body 30 when the mouthpiece body 6 is retracted, and is restricted to the aforementioned direction during advancement. The rotation operation of the second rotating cleaning body 30 in the rotation direction W3 is inclined in the circumferential direction.
且因為將刷毛體(起毛布)30b均等地捲附在軸30a的全圓周方向，所以容易保持吸入室Q2的氣密， 且可以減小從吸入室Q2漏出的噪音和藉由流動於間隙的氣流所發生的噪音。 Further, since the brush body (pilling fabric) 30b is equally wound around the entire circumferential direction of the shaft 30a, it is easy to maintain the airtightness of the suction chamber Q2. It is also possible to reduce the noise leaking from the suction chamber Q2 and the noise generated by the air flow flowing through the gap.
且第2旋轉清掃體30，是如第3圖所示，在左右具有間隙，但是吸口體6與地面M接觸地清掃時，因為是藉由吸引在中央部被吸近，將流速快的中央側的間隙塞住的方式移動，所以可以抑制漏出噪音。 In the second rotating cleaning element 30, as shown in FIG. 3, when there is a gap between the right and left sides, the suction body 6 is cleaned in contact with the floor M, and the center of the flow velocity is fast because it is sucked in the center portion by suction. The side gap is moved in such a way that it can suppress leakage noise.
第7圖，是將本發明的實施例的吸口體遠離地面的狀態的側面圖。 Fig. 7 is a side view showing a state in which the mouthpiece of the embodiment of the present invention is separated from the ground.
如第7圖所示，吸口體6是與地面M未接觸情況時，第1旋轉清掃體20的下端部20u，是位於比第2旋轉清掃體30的下端部30u更垂直方向的下方。且，設在連結部12的下面的車輪16a會突出，使毛刷驅動開關16成為斷開(OFF)，停止第1旋轉清掃體20的動作。 As shown in Fig. 7, when the mouthpiece 6 is not in contact with the floor M, the lower end portion 20u of the first rotary cleaning element 20 is located below the lower end portion 30u of the second rotary cleaning body 30. Further, the wheel 16a provided on the lower surface of the coupling portion 12 is protruded, and the brush drive switch 16 is turned OFF, and the operation of the first rotary cleaning body 20 is stopped.
第8圖，是本發明的實施例的吸口體與地面接觸的狀態的側面圖。 Fig. 8 is a side view showing a state in which the mouthpiece of the embodiment of the present invention is in contact with the ground.
如第8圖所示，吸口體6與地面M接觸的話，車輪16a被壓入，毛刷驅動開關16成為導通(ON)，第1旋轉清掃體20朝W1方向(圖示逆時針方向)旋轉。此時，與地面M接觸的領域的毛刷20a、20b、20c是藉由彎曲，就可以將毛刷20a、20b、20c及地面M的接觸量充分地確保，可以將地面M的塵埃有效地撥入。 As shown in Fig. 8, when the mouthpiece 6 is in contact with the floor M, the wheel 16a is pushed in, the brush drive switch 16 is turned on, and the first rotary cleaning body 20 is rotated in the W1 direction (counterclockwise direction). . At this time, the brushes 20a, 20b, and 20c in the field in contact with the floor M can sufficiently ensure the contact amount of the brushes 20a, 20b, and 20c and the floor M by bending, and the dust of the floor M can be effectively Dial in.
同樣地，第2旋轉清掃體30是藉由與地面M接觸，與地面M接觸的領域的刷毛體(起毛布)30b是藉 由彎曲，可以將刷毛體(起毛布)30b及地面M的接觸阻力充分地確保。 Similarly, the second rotating cleaning body 30 is a body of the brush body (hairing cloth) 30b that is in contact with the ground M by contact with the ground M. By the bending, the contact resistance of the bristle body (hairing cloth) 30b and the floor surface M can be sufficiently ensured.
第9圖，是本發明的實施例的吸口體6為後退的狀態的側面圖。 Fig. 9 is a side view showing a state in which the mouthpiece 6 of the embodiment of the present invention is retracted.
如第9圖所示，第2旋轉清掃體30，是刷毛體(起毛布)30b及隔壁彎曲部11e的接觸阻力因為是比刷毛體(起毛布)30b及地面M的接觸阻力小，所以朝由W3顯示的旋轉方向旋轉，將地上的塵埃DS朝吸入室Q2內導入。被導入的塵埃DS，是從吸入室Q2(第6圖參照)通過流路R(第3圖參照)朝吸口接頭13的通路搬運，其後，通過延長管5、操作管4及管部3朝吸塵器本體2的集塵部2b被吸引(第1圖參照)。藉由集塵部2b使塵埃被去除的空氣，是通過無圖示的過濾器及電動送風機2a內，朝吸塵器本體2的外部被排出(第1圖參照)。 As shown in Fig. 9, the contact resistance of the brush body (pilling fabric) 30b and the partition wall bending portion 11e in the second rotary cleaning body 30 is smaller than the contact resistance between the brush body (hair cloth) 30b and the floor M, so Rotating in the direction of rotation indicated by W3, the dust DS on the ground is introduced into the suction chamber Q2. The introduced dust DS is conveyed to the suction port 13 through the flow path R (refer to FIG. 3) from the suction chamber Q2 (refer to FIG. 6), and then passes through the extension pipe 5, the operation pipe 4, and the pipe portion 3. The dust collecting portion 2b of the cleaner body 2 is sucked (refer to FIG. 1). The air in which the dust is removed by the dust collecting portion 2b is discharged into the outside of the cleaner body 2 through a filter (not shown) and the electric blower 2a (refer to Fig. 1).
第10圖，是本發明的實施例的吸口體6為前進的狀態的側面圖。 Fig. 10 is a side view showing a state in which the mouthpiece 6 of the embodiment of the present invention is advanced.
如第10圖所示，第2旋轉清掃體30，因為刷毛體(起毛布)30b及隔壁彎曲部11e的接觸阻力是比刷毛體(起毛布)30b及地面M的接觸阻力大所以不旋轉，可以防止朝吸入室Q2內被吸引的塵埃朝吸口本體11的後方被掃出。特別是藉由第1旋轉清掃體20的旋轉朝吸入室Q2內被吸引的塵埃是朝後方被彈開，可以抑制朝吸口本體11的後方躥出。 As shown in Fig. 10, the second rotating cleaning body 30 does not rotate because the contact resistance between the bristle body (hair raising cloth) 30b and the partition wall bending portion 11e is larger than the contact resistance between the brush body (hair raising cloth) 30b and the floor surface M. It is possible to prevent the dust sucked into the suction chamber Q2 from being swept out toward the rear of the mouthpiece body 11. In particular, the dust sucked into the suction chamber Q2 by the rotation of the first rotary cleaning body 20 is bounced toward the rear, and it is possible to suppress the rearward suction toward the suction nozzle main body 11.
被吸引的塵埃DS，是從吸入室Q2(第6圖參照)通過流路R(第3圖參照)朝吸口接頭13的通路搬運，其後，通過延長管5、操作管4及管部3朝吸塵器本體2的集塵部2b被吸引(第1圖參照)。藉由集塵部2b使塵埃被去除的空氣，是通過無圖示的過濾器及電動送風機2a內，朝吸塵器本體2的外部被排出(第1圖參照)。 The sucked dust DS is conveyed from the suction chamber Q2 (refer to FIG. 6) through the flow path R (refer to FIG. 3) to the suction port 13 and then passes through the extension pipe 5, the operation pipe 4, and the pipe portion 3. The dust collecting portion 2b of the cleaner body 2 is sucked (refer to FIG. 1). The air in which the dust is removed by the dust collecting portion 2b is discharged into the outside of the cleaner body 2 through a filter (not shown) and the electric blower 2a (refer to Fig. 1).
如此，依據本實施例的話，藉由在第1旋轉清掃體的後方設有與地面M接觸的第2旋轉清掃體30，將吸口體6後退時(將吸口體6朝後方拉引時)，第2旋轉清掃體30是藉由與地面M的接觸阻力而旋轉，就可以將吸口本體11的後方的塵埃朝吸入室Q2內吸入。 According to the present embodiment, when the second rotary cleaning body 30 that is in contact with the floor surface M is provided behind the first rotary cleaning body, when the mouthpiece body 6 is retracted (when the mouthpiece body 6 is pulled rearward), The second rotary cleaning body 30 is rotated by the contact resistance with the floor surface M, so that the dust behind the nozzle body 11 can be sucked into the suction chamber Q2.
且將吸口體6前進時(將吸口體6朝前方推壓時)，第2旋轉清掃體30的旋轉因為被限制，所以可以防止藉由第1旋轉清掃體20朝吸入室Q2內被撥入的塵埃，朝吸口本體11的後方被掃出。 When the mouthpiece 6 is advanced (when the mouthpiece 6 is pushed forward), the rotation of the second rotary cleaning body 30 is restricted, so that it can be prevented from being dialed into the suction chamber Q2 by the first rotary cleaning body 20. The dust is swept out toward the rear of the mouthpiece body 11.
且依據本實施例的話，因為不必要設置可動部作為限制第2旋轉清掃體30的旋轉方向的手段，所以構造簡單。且，藉由沙塵等的侵入，使限制功能減損的可能性也變小。 Further, according to the present embodiment, since it is not necessary to provide the movable portion as a means for restricting the rotation direction of the second rotary cleaning body 30, the structure is simple. Moreover, the possibility of derogating the restriction function is also reduced by the intrusion of dust or the like.
且在本實施例中，第2旋轉清掃體30的刷毛體(起毛布)30b的先端，是具有可與隔壁彎曲部11e的表面整體接觸的刷毛高度，但是不一定必要與隔壁彎曲部11e的表面整體接觸，如第11圖所示，在隔壁彎曲部11e 的內側設置剖面形狀大致三角形狀的突起35a、35b、35c，藉由使這些的突起及刷毛體(起毛布)30b的先端接觸的方式設定刷毛高度，在旋轉方向W2中，摩擦阻力小幾乎可自由地旋轉，但是在旋轉方向W3中，摩擦阻力大幾乎成為鎖定狀態。 In the present embodiment, the tip end of the bristle body (hair raising cloth) 30b of the second rotary cleaning element 30 has a bristle height that can be in contact with the entire surface of the partition wall bending portion 11e, but does not necessarily have to be the partition wall bending portion 11e. The entire surface is in contact, as shown in Fig. 11, at the partition curved portion 11e The protrusions 35a, 35b, and 35c having substantially triangular cross-sectional shapes are provided on the inner side, and the height of the bristles is set such that the protrusions and the tip end of the bristle body (hairing cloth) 30b are in contact with each other, and the frictional resistance is small in the rotation direction W2. It rotates freely, but in the rotational direction W3, the frictional resistance is almost a locked state.
進一步說明詳細的話，第2旋轉清掃體30的旋轉驅動力，是刷毛體(起毛布)30b及地面M的摩擦力，第2旋轉清掃體30的旋轉制動力，是刷毛體(起毛布)30b及突起35a、35b、35c的摩擦力。起毛布30b的微細纖維是對於配管體30e朝圓周方向傾斜，該傾斜的方向，是以刷毛體(起毛布)30b與地面接觸的位置，從吸口體6的前方朝向後方。因此，將吸口體6前進時，起毛布30b及地面M的摩擦力即第2旋轉清掃體30的旋轉驅動力變小，刷毛體(起毛布)30b及突起35a、35b、35c的摩擦力即第2旋轉清掃體30的旋轉制動力變大，第2旋轉清掃體30的旋轉被限制。相反地將吸口體6後退時，刷毛體(起毛布)30b及地面M的摩擦力即第2旋轉清掃體30的旋轉驅動力變大，刷毛體(起毛布)30b及突起35a，35b、35c的摩擦力即第2旋轉清掃體30的旋轉制動力變小，第2旋轉清掃體30可旋轉。 Further, the rotational driving force of the second rotating cleaning body 30 is the frictional force of the brush body (pilling fabric) 30b and the floor surface M, and the rotational braking force of the second rotating cleaning body 30 is the brush body (hairing cloth) 30b. And the frictional force of the protrusions 35a, 35b, 35c. The fine fibers of the raised fabric 30b are inclined toward the circumferential direction of the pipe body 30e, and the direction of the inclination is a position where the brush body (hair raising cloth) 30b comes into contact with the ground, and is directed rearward from the front side of the mouthpiece body 6. Therefore, when the mouthpiece 6 is advanced, the frictional force of the raised fabric 30b and the floor M, that is, the rotational driving force of the second rotary cleaning body 30 is reduced, and the frictional force of the brush body (hair cloth) 30b and the protrusions 35a, 35b, 35c is The rotational braking force of the second rotary cleaning body 30 is increased, and the rotation of the second rotary cleaning body 30 is restricted. On the other hand, when the mouthpiece 6 is retracted, the frictional force of the brush body (hair cloth) 30b and the floor surface M, that is, the rotational driving force of the second rotary cleaning body 30 is increased, and the brush body (hair cloth) 30b and the protrusions 35a, 35b, 35c The frictional force of the second rotary cleaning body 30 is reduced, and the second rotary cleaning body 30 is rotatable.
又，在本實施例中，在第2旋轉清掃體30的旋轉方向W3時，成為幾乎鎖定狀態，但是不一定必要鎖定，在吸口體6前進的狀態下第2旋轉清掃體30的旋轉，是與自由時相比較慢的話，藉由第1旋轉清掃體20 就可以防止朝吸入室Q2內被撥入的塵埃朝吸口本體11的後方被掃出。 In the present embodiment, the second rotating cleaning body 30 is in a nearly locked state when it is in the rotational direction W3 of the second rotating cleaning body 30. However, the second rotating cleaning body 30 is rotated in a state in which the mouthpiece 6 is advanced. If it is slower than the free time, the first rotating cleaning body 20 It is possible to prevent dust that has been dialed into the suction chamber Q2 from being swept out toward the rear of the mouthpiece body 11.
又，在本實施例中，雖在第2旋轉清掃體30的表面設置刷毛體(起毛布)30b，刷毛體(起毛布)30b，是設成與吸口體6的一部分接觸，在吸口體6的後退時容許旋轉動作，且在前進時限制旋轉動作的方式朝圓周方向傾斜設置，但是不限定於此。只要可由簡單的構成，達成旋轉時，限制一方向的旋轉，容許另一方向的旋轉的效果的構件、安裝方式即可。例如，即使將本實施例的刷毛體(起毛布)30b作成彈性體也可達成上述效果。 Further, in the present embodiment, the bristle body (pilling fabric) 30b is provided on the surface of the second rotary cleaning element 30, and the bristle body (pilling fabric) 30b is provided in contact with a part of the mouthpiece body 6, and the mouthpiece body 6 is provided. The rotation operation is allowed to be reversed, and the manner of restricting the rotation operation during the forward movement is inclined in the circumferential direction, but the invention is not limited thereto. As long as the rotation can be achieved, it is sufficient to limit the rotation in one direction and to allow the effect of the rotation in the other direction. For example, the above effects can be achieved even if the bristle body (hairing cloth) 30b of the present embodiment is made into an elastic body.
依據如以上所述本形態例的話，由簡單的構成，在前進時因為第2旋轉清掃體30是幾乎固定而與地面接觸，所以將從前方吸入的塵埃從第2旋轉清掃體30朝後方排出困難，且，在後退時第2旋轉清掃體30旋轉就可以將吸口體6的後方的塵埃朝吸入室Q2搬運，可以抑制塵埃的吸剩。且，在本實施例中雖說明了第1旋轉清掃體、及使用將此旋轉驅動的電動機的情況，但是使用藉由吸塵器本體2的電動送風機2a發生的吸引力將第1旋轉清掃體驅動的話，即使沒有第1旋轉清掃體仍可獲得同樣的效果。 According to the present embodiment, as described above, the second rotating cleaning body 30 is almost fixed and comes into contact with the ground during the forward movement. Therefore, the dust sucked from the front is discharged rearward from the second rotary cleaning body 30. When the second rotating cleaning body 30 is rotated, the dust behind the mouthpiece 6 can be conveyed to the suction chamber Q2, and dust absorption can be suppressed. In the present embodiment, the first rotating cleaning body and the motor that is driven by the rotation are described. However, when the first rotating cleaning body is driven by the suction force generated by the electric blower 2a of the cleaner body 2, the first rotating cleaning body is driven. The same effect can be obtained even without the first rotating cleaning body.
