也成爲繃緊狀態而張力施加於排塵口部，所以挾持具的安 裝方式不完全的情況，粉塵可能會從排塵口噴出。 在專利文獻1記載的吸塵器用集塵袋，由於在集塵袋 最開始就形成有排塵口，並且安裝有夾持具，所以會限定 使用夾持具的方式，使用者的選擇很少，而可能會減少使 用方便性。 在專利文獻1記載的吸塵器用集塵袋，在集塵袋的內 面附著有塵埃（垃圾），使用者很難排除該塵埃（垃圾） 〇 本發明的第一目的，要提供一種吸塵器用集塵袋及吸 塵器，其集塵袋可再次使用。 本發明的第二目的，要提供一種吸塵器用集塵袋及吸 麈器，當以可裝卸的構件將集塵袋的塵埃排出開口封閉時 ，防止：雖然已封閉但仍從塵埃排出口噴出塵埃的情形。 本發明的第三目的，要提供一種吸塵器用集塵袋及吸 塵器，使用者能選擇：將集塵袋丟棄的使用方式、以及將 集塵袋再次使用的使用方式。本發明的第四目的，要提供 一種吸塵器用集塵袋及吸塵器，容易將來自集塵袋的塵埃 排出。 [用以解決課題的手段] 本發明的吸塵器用集塵袋，在將袋構件安裝於吸塵器 而膨脹的狀態’袋構件的下側部分幾乎沒有膨脹，讓袋構 件的外表面的局部接觸於吸塵器的袋構件收容室（例如集 -6- 201143703 塵部）內的吸氣側面（例如內面）；其特徵爲：袋構件的 上下開口，袋構件的上部開口被接合，袋構件的下部開口 藉由可裝卸的構件（例如夾子）所封閉。 本發明’在袋構件的下部，朝袋構件的左右方向形成 有剪截線’藉由剪截所形成的袋構件的下部開口，藉由可 裝卸的構件（例如夾子）所封閉。 本發明，袋構件的內層，是由：含有聚四氟乙烯的材 料所構成，袋構件的下部開口，藉由可裝卸的構件（例如 夾子）所封閉。 [發明效果] 藉由本發明，藉由可裝卸的構件將袋構件的下部封閉 ’而在將袋構件內的塵埃從下部開口排出之後，能藉由可 裝卸的構件將其封閉，所以能再次使用集塵袋。 藉由本發明’袋構件在安裝於吸塵器而膨脹的狀態， 袋構件的下側部分幾乎沒有膨脹，讓袋構件的外表面的局 部接觸於吸塵器的袋構件收容室內的吸氣側面，而讓可裝 卸的構件大幅偏移或脫落等的張力，不會施加在袋構件的 形成有塵埃排出開口側，所以當以可裝卸的構件將集塵袋 的塵埃排出開口封閉時，能防止：雖然已封閉但仍從塵埃 排出口噴出麈埃的情形。 藉由本發明，在袋構件的下部，朝袋構件的左右方向 形成有剪截線，藉由剪截所形成的袋構件的下部開口，藉 由以可裝卸的構件將其封閉，使用者能選擇：將集塵袋丟 201143703 棄的使用方式、以及將集塵袋再次使用的使用方式，能提 升使用方便性。而藉由本發明，在袋構件的下部，藉由朝 袋構件的左右方向形成剪截線，則使用者能容易地辨識剪 截位置。 藉由本發明，藉由讓袋構件的內層，是由：含有聚四 氟乙烯的材料所構成，則能容易將來自集塵袋的塵埃排出 【實施方式】 本發明，在將袋構件安裝於吸塵器而膨脹的狀態，袋 構件的下側部分幾乎沒有膨脹，讓袋構件的外表面的局部 接觸於吸塵器的袋構件收容室（例如集塵部5 )內的吸氣 側面（例如內面）：其特徵爲：袋構件的上下開口，袋構 件的上部開口被接合，袋構件的下部開口藉由可裝卸的構 件（例如夾子27)所封閉。 本發明，在袋構件的下部，朝袋構件的左右方向形成 有剪截線，藉由剪截所形成的袋構件的下部開口，藉由可 裝卸的構件（例如夾子27 )所封閉。 本發明，袋構件的內層，是由：含有聚四氟乙烯的材 料所構成，袋構件的下部開口，藉由可裝卸的構件（例如 夾子2 7 )所封閉。 以下參考圖面針對本發明的實施例1、2加以說明。 [實施例1 ] -8- 201143703 第1圖是顯示本發明的實施例的吸塵器的外觀立體圖 。第2圖是從本發明的實施例的吸麈器主體的下主體殻體 3將上主體殼體4與蓋部8分離的狀態的外觀立體圖。第 3圖是本發明的實施例的吸塵器主體的中央縱剖面圖。第 2圖、第3圖是顯示集塵袋20在集塵部5內膨脹的狀態 〇 如第1圖所示，吸塵器1，在吸塵器主體2的軟管連 接口部10連接著軟管12的其中一端也就是連接接頭12a ，在軟管12的另一端連接著把手操作管13的其中一端。 在把手操作管13設置有：使用者用來切換電動送風機9 的吸入力的強弱等、吸塵器1的運轉模式的開關1 6。在 把手操作管13的另一端，連接著伸縮接頭管14的其中一 端，在伸縮接頭管1 4的另一端連接著大致T字形的地板 用的吸口 1 5。吸口 1 5與伸縮接頭管1 4與把手操作管1 3 ，藉由使用者的操作可互相裝卸，軟管12與吸塵器主體 2可藉由使用者的操作互相裝卸。伸縮接頭管1 4，可藉由 使用者的操作而伸縮。也可取代伸縮接頭管1 4，用不伸 縮的接頭管。在吸口 1 5與伸縮接頭管1 4之間’、或在伸縮 接頭管14與把手操作管13之間，也可連接與地板用的吸 口 1 5不同的輔助吸口（配件）。 如第2圖所示，吸塵器主體2，藉由上主體殻體4與 下主體殼體3與蓋部8形成外輪廓。在吸塵器主體2的後 側，內建有：產生吸引力的電動送風機9、以及用來將電 力供給到該電動送風機9的電源線1 9。電源線1 9，捲繞 -9 - 201143703 於：設置在吸塵器主體2的電源線捲線器。電動送風機9 與電源線捲線器’是鄰接配置在吸塵器主體2的左右方向 。在電動送風機9的前側’形成有集塵部（集塵室）5。 集塵部5的前側，與軟管連接口部連通’集塵部5的 後側，隔介著保護過濾器1 8而連通於電動送風機9。也 就是說，在集塵部5的前面，形成有軟管連接口部10’ 在集塵部5的後面形成有保護過濾器18。在集塵部5可 裝卸地安裝有集塵袋20。而保護過濾器1 8，並不是必須 的構造。而所謂的吸塵器主體2的前側，是配置軟管連接 口部1 0側，所謂後側爲其相反側。所謂吸塵器主體2的 上下方向，是在將吸塵器主體2橫置的狀態（使用狀態） 的上下方向。所謂吸塵器主體2的左右方向，是與前後方 向垂直且與上下方向也垂直的方向。 藉由將電動送風機9驅動時的吸氣力，從吸口 1 5將 含塵空氣吸入’將吸入的含塵空氣經由伸縮接頭管14、 把手操作管1 3、軟管1 2，從軟管連接口部1 〇吸入到吸塵 器主體2，將塵埃收集（集塵）到集塵袋20。通過集塵袋 2〇的空氣流，經由保護過濾器18被電動送風機9吸引而 升壓。沒有被集塵袋20收集的細微的灰塵，以在電動送 風機9的後側的上側配置的排氣過濾器3 2過濾收集，將 空氣朝吸塵器主體2外排氣。排氣過濾器32，其通氣阻 力較集塵袋20更阔’其集塵率也較高。 如第2圖、第3圖所示，吸塵器主體2,在上主體殼 體4與下主體殼體3與蓋部8之間配置的集塵部5內，可 -10 - 201143703 裝卸地安裝著集塵袋20。蓋部8，可轉動地安裝在上主體 殼體4的上側。集塵袋2〇的出入，是將蓋部8開啓來進 行’將集塵袋2 0插入安裝到集塵部5，將上蓋部8關閉 來進行吸塵器1的運轉。 在集塵部5內’在集麈袋2〇與電動送風機9之間， 設置有：防止將殘留於集塵部5內的塵埃吸入到電動送風 機9而用來保護電動送風機9的保護過濾器18，並且配 置除塵單元7。因爲塵埃而膨脹的袋構件21的外表面， 會接觸於除塵單元7。該除塵單元7擺動，藉由使袋構件 2 1的內側或上側的外表面振動，使附著在袋構件2 1的內 面的塵埃震落到袋構件21內。利用除塵單元7所進行的 除塵動作，是當使用者指示吸塵器1停止運轉時，或使用 者指示吸塵器1開始運轉時，或依照使用者的任意指示來 進行較佳。 下主體殼體3，具備有：使該吸塵器主體2行駛於地 板面的行駛車輪1 1、與導引車輪40。行駛車輪1 1，配置 在下主體殼體3的後部的左右側面，導引車輪40，配置 在下主體殻體3的前部的底面。並且，在上主體殼體4的 上部可自由出沒地安裝有把手6，能讓使用者搬運吸塵器 主體2。 與插入到軟管連接口部10的軟管12的連接接頭12a 、以及用來防止塵埃朝軟管1 2掉入（逆流）的單向閥3 1 成爲一體的由彈性體所構成的密封構件，抵接成氣密狀態 ，當該單向閥31開啓時，讓含塵空氣流，從流入口 3 0通 -11 - 201143703 過在集塵袋20設置的開口部26而流入到集塵袋20內 這裡與單向閥31成爲一體的密封構件，與設置在集塵 20的口板（口芯部）22緊貼，也具有讓塵埃不會溢出 功能。 接著，針對吸塵器主體2內部的配置加以說明。軟 連接口部10，從上方觀察，在吸塵器主體2的寬度方 (左右方向）的大致中央，且配置在吸塵器主體2的前 。集麈袋20的流入部也就是開口部26，也同樣地在集 部5的寬度方向（左右方向）的大致中央，且配置在集 部5內的前面。藉由這樣配置方式，則在集塵部5的入 部分不需要設置彎曲部等，可以減少通氣損失。 接著參考第3圖、第8圖針對集塵部5加以說明。 8圖是第3圖的E部的放大圖。 如第3圖所示，在集塵部5內的前下部（較流下 3 〇更下側），具有座部3 6，座部3 6具有朝下方凹入的 狀，該座部3 6的凹形狀部分可裝卸地安裝著口板22的 端。在座部36，設置有：朝吸塵器主體2的左右方向 伸的轉動軸37，座部36，可朝吸塵器主體2的前後方 傾斜動作。在轉動軸3 7周圍，安裝有環狀彈簧，藉由 狀彈簧，將轉動軸3 7朝第3圖中順時鐘方向彈壓。藉 ，將座部36的凹孔彈壓成朝向上後方向。 在集塵部5內的前面的上部（較流入口 3 0更上側 ’設置有：側剖面朝下的大致Π字型的夾板2 8。該夾 28的大致门字形的其中一端，形成卡止部3 8。在夾板 袋 的 管 向 面 塵 塵 口 第 Ρ 形 下 延 向 環 此 板 -12- 28 201143703 的大致门字型的卡止部3 8的外側，設置有：朝向外側延 伸形成的鉤部29。在夾板28的與大致门字型的卡止部38 相反側的外側，設置有：朝向外側延伸形成的補強部3 3 。藉由設置於夾板28的卡止部38來保持口板22，在將 蓋部8關閉的狀態，設置於夾板28的補強部33，藉由朝 向下方延伸的肋部34而被卡止於蓋部8的前端下部。因 此，在塵埃聚集於集塵袋20的狀態，將電動送風機9驅 動時，也將集塵袋20朝電動送風機9側拉伸，防止口板 22遠離與單向閥31成爲一體的彈性體密封構件，防止塵 埃溢出。而單向閥31的功能，是用來防止：積聚在集塵 袋20的麈埃，從設置於集塵袋20的開口部26，朝設置 於軟管12的連接接頭12a側逆流。集塵袋20，也可具備 有：在塵埃聚集於集塵袋20內之後，當將該集塵袋20丟 棄時，將設置於口板22的開口部26封閉的密封構件（沒 有圖示）。 爲了將該集塵袋20安裝於吸塵器主體2內的集塵部 5，在將轉動軸3 7作爲旋轉軸而朝電動送風機9側傾斜的 座部36，安裝集塵袋20的口板22的下端，將該口板22 與座部36朝向前方抬起，將設置於夾板28的卡止部38 鉤在口板22的上端來安裝即可。夾板28如果作成讓轉動 軸3 5可作爲旋轉軸轉動的話，則容易進行集塵袋20的安 裝。設置於夾板28的鉤部29、或於補強部33、蓋部8設 置的肋部39，並不設置在口板22的寬度方向的中央附近 ，而設置在口板22的寬度方向的兩端附近。 -13- 201143703 接著，使用第4圖來說明吸塵器用的集塵袋20的槪 要。第4圖是本發明的實施例的集塵袋20的外觀立體圖 。第4圖是顯示塵埃並未聚集於集塵袋20內’集塵袋20 沒有膨脹的狀態。在集塵袋2 0沒有膨脹的狀態’集塵袋 20大致爲平面狀。第4圖（a)是顯示藉由夾子27夾持 集塵袋20的下端的狀態，第4圖（b)是顯示沒有藉由夾 子27夾持集塵袋20的下端的狀態。 集塵袋20，具備有：具有圓形的開口部26的以厚紙 或塑膠等構成的大致四邊形的口板22、以及具有與開口 部2 6對應的開口，以紙、布、獸毛或塑膠材等的不織布 等所構成的具有通氣性的袋構件21。在口板22的上端的 左右方向的大致中央，形成有1 〇mm左右的深度的缺口部 25。缺口部25，當未將集塵袋20安裝於集塵部5內時， 具有用來防止蓋部8完全關閉的蓋部封閉阻止構件的功能 。藉此，使用者能辨識出在集塵部5內沒有安裝集塵袋 20，能夠防止：在集塵部5內沒有安裝集塵袋20而吸塵 器1就運轉的情形。將口板22之中形成有缺口部25側作 爲集塵袋20的上側。袋構件21，將不同種類的不織布以 複數層（例如三層）積疊在厚度方向形成較佳。 在袋構件21的最內層的材料，使用由聚四氟乙烯所 構成的多孔質膜較佳，藉由使用由聚四氟乙烯所構成的多 孔質膜’袋構件21內面的排塵性較佳，使用者能容易將 塵埃從袋構件21內排出。即使使用者不將附著在袋構件 2 1內面的塵埃刮出，也能將塵埃從袋構件2 1內排出成可 -14- 201143703 再利用的程度，所以也能防止刮出動作伴隨的塵埃 。也可取代使用由聚四氟乙烯所構成的多孔質膜’ 構件2 1的最內面塗覆上排塵性較佳的材料。 在袋構件2 1的最外層與最內層之間的中間層 ，使用由聚四氟乙烯所構成的多孔質膜，在最內層 織布也可以。因爲由聚四氟乙烯所構成的多孔質膜 所以當較大的塵埃衝撞到由聚四氟乙烯所構成的多 時可能會破損，所以藉由在由聚四氟乙烯所構成的 膜的內側使用堅固的不織布，則可防止由聚四氟乙 成的多孔質膜破損。因此，由聚四氟乙烯所構成的 膜，在最內層或在中間層都可以，只要使用在內層 袋構件21黏接在口板22的背面側。袋構件. 板22的黏接部分，並未涵蓋口板22的全體，口相 外周部分的l〇mm〜l5mm的程度並未與袋構件21 非黏接部17)。袋構件21黏接於口板22的開口 。當口板22安裝於吸塵器1的集塵部5時，雖然 於夾板28的鉤部29卡合，而如果袋構件21黏接 22的外周端部的話，則口板22與鉤部29無法卡 可能以鉤部2 9使袋構件21損傷。因此，在本實施 板22的外周部分並未與袋構件21黏接。口板22 件21沒有黏接的部分，至少爲口板22的一片，也 鉤部29卡合側的片部是必要的，而另一片部黏接 22的端部也可以。 袋構件2 1，當展開時爲長方形，使其長方形 的揚起 而在袋 的材料 使用不 較薄， 孔質膜 多孔質 烯所構 多孔質 即可。 Η與口 i 22的 黏接（ 部週邊 與設置 至口板 合，而 例，口 與袋構 就是與 至口板 的其中 -15- 201143703 一邊與相對向邊重题，而以黏接劑黏接而形成爲筒狀體。 在該狀態，筒狀體，上下開口。然後將筒狀體折疊，將已 折疊的筒狀體的上端（上側開口部分）折返兩次，以黏接 劑（接合構件）黏接，形成折返部23。因此，袋構件21 的上端隨時封閉著。折返次數，是一次或三次以上都可以 。也可取代黏接劑，藉由訂書機的訂書針等的配件（接合 構件）來接合。另一方面，將已折疊的筒狀體的下端（下 側開口部分）折返兩次，形成折返部24。折返次數，同 樣地是一次或三次以上都可以。在折返之後，不使用黏接 劑（接合構件）黏接，藉由夾子27(夾持具）從外側將 折返部24夾入。藉此，使用者只要將夾子27卸下，將折 返部解開，則能將袋構件2 1的下端開口。夾子27具有將 袋構件21的下側開口部分封閉的封閉構件的功能。 從在口板22的開口部26的上下方向的中央也就是上 下中心線（第4圖（b )中的一點破折線），到集塵袋20 的下端的長度（集塵袋20的下部長度）li，相較於從口 板2 2的開口部2 6的上下中心線到集塵袋2 0的上端的長 度（集塵袋20的上部長度）L2，更小i〇mm左右。也就 是具有L1<L2的關係。可是爲L14L2也可以。從口板 22的開口部26的上下中心線到口板22的上端的長度、 與從口板2 2的開口部2 6的上下中心線到口板2 2的下端 的長度’大致相等。因此’口板22的上下方向的中央與 開口部26的上下方向的中央大致一致。 以該方式，不將集塵袋20的下端接合，藉由以夾子 -16- 201143703 27可裝卸地夾持，讓使用者，能將聚集於集塵袋2〇內的 塵埃從集塵袋20的下端開口排出，藉由以夾子27再次夾 持集塵袋20的下端，則能再次利用集塵袋20。因此可以 節省集塵袋20的資源避免浪費。由於將夾子27設置在與 電動送風機9的吸氣口相對向的面也就是集塵袋20的內 面（後面）以外，所以可避免：因爲夾子27妨礙吸氣或 造成氣流紊亂的情形。隨著使用時間變長，細灰塵會附著 於袋構件21，而袋構件21的通氣性降低，所以集塵袋20 的再使用次數爲兩' 三次左右較佳。並且，由於將夾子 27設置在與電動送風機9的吸氣口相對向的面也就是集 塵袋20的內面（後面）以外，所以可避免：因爲夾子27 妨礙吸氣或造成氣流紊亂的情形。 接著，第5圖爲本發明的實施例的夾子27的外觀立 體圖。第5圖（a)顯示從夾子27的其中一方觀察的立體 圖，第5圖（b)是顯示從夾子27的相反側的另一方觀察 的立體圖。第6圖是發明的實施例的集塵袋20的外觀立 體圖。第6圖是顯示在集塵袋20安裝著夾子27而並未夾 持的狀態。 夾子27是藉由合成樹脂或金屬所構成較佳。夾子27 ，具備有：棒狀的上腕構件41與棒狀的下腕構件42。上 腕構件41及下腕構件42的長度，較集塵袋20 (袋構件 21)的下端部分的左右方向的長度更長。因此，夾子27 的長度也較集塵袋20(袋構件21)的下端部分的左右方 向的長度更長。上腕構件41及下腕構件42的寬度，小於 -17- 201143703 集塵袋20的下端部分的折返寬度。可是，上腕構件4i及 下腕構件42的寬度’與集塵袋20的下端部分的折返寬度 相比’相等或較大都可以》上腕構件41的其中一端爲直 線狀，另一端_折成大致L字形。上腕構件41的彎曲成 大致L字型的部分，可轉動地與下腕構件42的另一端連 結（連結部43 )。在下腕構件42的其中一端，可轉動地 連結著剖面爲大致门字形的止動件45 (連結部46)。止 動件45，當相對於下腕構件42將上腕構件41關閉時， 將上腕構件41的其中一端保持在大致门字形的內側，具 有保持封閉狀態的功能。也可取代止動件44，利用輪橡 膠。也可取代止動件44，把用來讓上腕構件41與下腕構 件42朝相對關閉方向彈壓的彈簧等的彈性構件，設置在 連結部43附近。 在下腕構件42的其中一端與另一端的中間部分，接 合著：剖面爲大致门字型的止動件44。如第6圖所示， 止動件44，具有用來防止集塵袋20的下端偏移的功能。 也就是說，止動件44，在藉由夾子27將集塵袋20的下 端部分夾持的狀態，可防止夾子27偏移或脫落。並且， 止動件44，當將夾子安裝於集塵袋20的下端部分時，讓 使用者容易定位。也就是說，藉由將夾子27安裝於集塵 袋20的下端側，防止夾子27從集塵袋20的下端部分偏 移而脫落的情形，相反地，藉由將夾子27安裝在集塵袋 2 0的中央側，可以防止集塵袋2 0內的集塵容量變小。止 動件44的剖面，不是Π字形而爲大致L字形也可以。止 -18- 201143703 動件44，不是沿著下腕構件42延伸設置而是局部突起也 可以。可是，止動件44並不是必須的構造’沒有也可以 。在上腕構件41之中與下腕構件42的相對向面、下腕構 件42之中與上腕構件41相對向面的其中之一或兩方，也 可形成橡膠等的摩擦係數較高的可彈性變形的構件。藉由 該構件，在藉由夾子27夾持集塵袋20的下端部分的狀態 ，能防止夾子27偏移或脫落。並且藉由該構件的彈性力 ，將集塵袋20的下端部分確實地封閉，能防止塵埃從集 塵袋20的下端吸出。 如本實施例的夾子27，將集塵袋20的下端部分涵蓋 左右方向的全面夾入的話，則集塵袋20的下端部分的折 返次數爲零次也可以。也就是說，不進仃折返’在集塵袋 2 〇的下端開口的狀態，藉由夾子2 7將該開口夾入而封閉 也可以。相反的，如果將集塵袋2 0的下端部分折返一次 以上的話，則也可如夾子2 7，不將集塵袋2 0的下側部分 涵蓋左右方向的全面夾入，而將集塵袋20的下端部分的 局部封閉也可以。只要將集塵袋20的下端部分的至少50 %以上或複數部位夾入的話，則塵埃就不會從集塵袋2 0 的下端開口吸出。例如，也可取代夾子27，而使用圓夾 子或Z型夾子、轉動夾子。 第7圖是顯示本發明的實施例的集麈袋20的捆包時 的狀態的側視圖。袋構件2 1，折疊出：相對於黏接著口 板22的袋構件21的中央部分，沒有黏接口板22的袋構 件2

中心線（第3圖的一點破折線），是與集塵袋20的開口 部26的中心線（第4圖（b)中的一點破折線）大致一致 。另一方面，流入口 3 0的中心線（第3圖的一點破折線 )、與電動送風機9的旋轉軸的中心線（第3圖的一點破 折線）沒有一致，電動送風機9的旋轉軸的中心線位於上 側。相較於吸塵器主體2的流入口 3 0，電動送風機9的 吸氣口位於稍上側。因此，從流入口 3 0流入的空氣，朝 稍上方流動，從電動送風機9的吸氣口吸入。將集塵部5 的上面形成的蓋部8，傾斜成從後側朝前側越位於下側。 另一方面，在集麈部5的底面的前後方向的中間部，用來 將導引車輪40安裝在吸塵器主體2的底面的腳輪安裝部 47 ’朝向集塵部5的內側突出，而如果將腳輪安裝部47 去除的話’則集塵部5的底面與吸塵器主體2的前後方向 也就是水平方向大致一致。腳輪安裝部47並不是必須的 構造。 從集塵部5的前部底面到流入口 3 0的中心線的高度 (集塵部5的前部的下部高度）爲Η1，從流入口 30的中 心線到集塵部5的前部上面的高度（集塵部5的前部的上 部闻度）爲Η 2，從集塵部5的後部底面到流入口 3 0的中 心線的高度（集塵部5的後部的下部高度）爲Η3，從流 入口 3 0的中心線到集塵部5的後部上面的高度（集塵部 -21 - 201143703 5的後部的上部高度）爲H4，則集塵部5的前部的高度 以（HI + H2 )表示，集塵部5的後部的高度以（H3 + H4 )表示。集塵部5的底面（下面），與吸塵器主體2的前 後方向也就是水平方向大致一致，所以Η 1与H3。集塵部 5的上面，傾斜成朝向前方變低’所以Η2 < Η4。因此’ (Η1+Η2) < (Η3+Η4)。集塵部5的前後方向的深度 爲W的話，則W< (Η1 + Η2)。也就是說，集塵部5內 部的前後方向的深度，小於集塵部5內部的高度。並且， 在較集塵部5的上下方向中央更下側，形成有流入口 30 。以流入口 30爲基準的話，集塵部5的上側空間較寬， 下側空間較窄。也就是，相對於集塵部5的上下方向的中 央，流入口 3 0的中心線位於下側。因此，Η 1 < H2，H3 < Η4。 如第3圖所示，當在集塵部5內集塵袋20膨脹時， 與開口部26相對向的集塵袋20的內面（後面）的外表面 ，接觸於：將集塵部5的內面（後面）的內表面形成的保 護過濾器18的前面。因此，集塵袋20膨眼時的集塵袋 20的前後方向的深度，與集塵部5內的前後方向的深度 W相比爲相同或較大。集塵袋20的底面（下面）的外表 面，在袋構件21的下側部分的內部幾乎沒有膨脹的狀態 ，與集塵部5的底面（下面）的內表面接觸。這是因爲在 袋構件2 1的中央部分讓空氣容易流入，所以袋構件2 1的 中央部分會先膨脹，而讓空氣不易流入到袋構件21的下 側部分，藉由袋構件21的中央部分的膨脹妨礙袋構件2 ! -22- 201143703 的下側部分的膨脹。另一方面，袋構件21的上側部分， 集塵部5的上側空間較寬，所以藉由袋構件2 1的中央部 分的膨脹不會妨礙袋構件21的上側部分的膨脹，讓袋構 件2 1的上側部分能夠膨脹。因此，當集塵袋2 〇膨脹時從 集塵袋2 0的底面到開口部2 6的中心線的高度，與集塵部 5的下部高度HI、H3相比爲相等或較大。而集塵袋20的 折疊狀態的下部長度L1，爲L1>H1，L1>H3。夾子27 接觸於：將集塵部5的底面的局部形成的腳輪安裝部47 。另一方面’集塵部20的上面的外表面，沒有接觸於集 塵部5的上面的內表面。也就是說，即使集塵袋2〇膨脹 ’從開口部26的中心線到集麈袋20的上面的高度，也小 於集塵部5的上部高度H2、H4。相對於集塵部5的上下 方向的中央’流入口 3 0位於下側，且集塵部5內的前後 方向的深度小於上下方向的高度的情況，集塵袋20的上 面處於張開的狀態，另一方面’集塵袋20的下面是處於 有餘裕的狀態（袋構件2 1的下側部分的內部幾乎沒有膨 脹的狀態）’也就是說，施加於集塵袋2 0的下面的張力 小於施加於集塵袋20的上面的張力，所以即使夾子27的 夾持稍微放鬆’也能防止：夾子27從集塵袋20脫落，塵 埃從集塵袋20的下面漏出的情形。只要集塵袋2〇的下面 處於有餘裕的狀態’則集塵袋20的上面的外表面接觸於 集塵部5的上面的內表面也可以。 將流入口 3 0作爲基準，在集塵部5的上下空間之中 較窄側，安裝夾子2 7即可，所以例如將流入口 3 〇作爲基 -23- 201143703 準，集塵部的上側空間較窄，下側空間較寬時，則

Fig. 4 is a view of the present invention. An external perspective view of the dust bag 20 of the embodiment. Fig. 4 is a view showing that the dust does not gather in the dust bag 20, and the dust bag 20 is not inflated. The dust bag 20 is not inflated. 20 is substantially planar. Fig. 4(a) shows a state in which the lower end of the dust bag 20 is held by the clip 27, and Fig. 4(b) shows a lower end where the dust bag 20 is not held by the clip 27. The dust bag 20 includes a substantially quadrangular orifice plate 22 made of thick paper or plastic having a circular opening portion 26, and an opening corresponding to the opening portion 26, which is made of paper, cloth, and beast. A permeable bag member 21 composed of a nonwoven fabric such as wool or a plastic material. A notch portion 25 having a depth of about 1 〇 mm is formed substantially at the center in the left-right direction of the upper end of the orifice plate 22. The notch portion 25 has a function of closing the stopper member for preventing the lid portion 8 from being completely closed when the dust bag 20 is not attached to the dust collecting portion 5. Thereby, the user can recognize that the dust collecting bag 20 is not attached to the dust collecting portion 5, and it is possible to prevent the dust collector 1 from being operated without the dust collecting bag 20 being attached to the dust collecting portion 5. The side of the mouth plate 22 in which the notch portion 25 is formed serves as the upper side of the dust bag 20. The bag member 21 is preferably formed by stacking different types of non-woven fabrics in a plurality of layers (e.g., three layers) in the thickness direction. In the material of the innermost layer of the bag member 21, a porous film made of polytetrafluoroethylene is preferably used, and the dust-removing property on the inner surface of the bag member 21 made of a porous film made of polytetrafluoroethylene is preferably used. Preferably, the user can easily discharge dust from the bag member 21. Even if the user does not scrape the dust adhering to the inner surface of the bag member 21, the dust can be discharged from the bag member 21 to the extent that it can be reused from -14 to 201143703, so that the dust accompanying the scraping operation can be prevented. . Instead of using the innermost surface of the porous membrane member 21 made of polytetrafluoroethylene, a material having a better dusting property may be applied. In the intermediate layer between the outermost layer and the innermost layer of the bag member 21, a porous film made of polytetrafluoroethylene may be used, and the innermost layer may be woven. Because of the porous film made of polytetrafluoroethylene, when large dust collides with a large amount of polytetrafluoroethylene, it may be damaged, so it is used inside the film made of polytetrafluoroethylene. A strong non-woven fabric prevents damage to the porous film made of polytetrafluoroethylene. Therefore, the film made of polytetrafluoroethylene may be the innermost layer or the intermediate layer, and may be adhered to the back side of the orifice plate 22 by using the inner layer bag member 21. Bag member. The adhesive portion of the plate 22 does not cover the entirety of the mouth plate 22, and the outer peripheral portion of the mouth portion has a degree of l〇mm~l5mm which is not in contact with the bag member 21. The bag member 21 is adhered to the opening of the mouth plate 22. When the flap 22 is attached to the dust collecting portion 5 of the vacuum cleaner 1, the hook portion 29 of the cleat 28 is engaged, and if the outer peripheral end portion of the pouch member 21 is bonded, the flap 22 and the hook portion 29 cannot be jammed. The bag member 21 is damaged by the hook portion 29. Therefore, the outer peripheral portion of the present embodiment plate 22 is not bonded to the bag member 21. The portion of the mouth plate 22 member 21 that is not bonded is at least one piece of the mouth plate 22, and it is also necessary that the hook portion 29 is engaged with the side portion of the side portion, and the end portion of the other piece portion is bonded. The bag member 2 1 has a rectangular shape when unfolded, so that the rectangular shape is raised and the material of the bag is not thin, and the porous membrane of the porous membrane is porous.黏 Η 口 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 22 In this state, the cylindrical body is opened up and down. Then, the cylindrical body is folded, and the upper end (upper side opening portion) of the folded cylindrical body is folded back twice to bond (bonding) The member is bonded to form the folded portion 23. Therefore, the upper end of the bag member 21 is closed at any time. The number of times of folding is one or three times or more. It is also possible to replace the adhesive, by a stapler of a stapler or the like. The fitting (joining member) is joined. On the other hand, the lower end (lower opening portion) of the folded cylindrical body is folded back twice to form the folded portion 24. The number of times of folding back is similar to one or three times. After the folding back, the adhesive member (joining member) is not bonded, and the folded portion 24 is sandwiched from the outside by the clip 27 (clamp). Thereby, the user can remove the clip 27 and unfold the folded portion. , the lower end of the bag member 2 1 can be opened The clip 27 has a function of a closing member that closes the lower opening portion of the bag member 21. From the center in the up and down direction of the opening portion 26 of the mouth plate 22, that is, the upper and lower center lines (a point of the broken line in Fig. 4(b)) The length to the lower end of the dust bag 20 (the lower length of the dust bag 20) li is compared to the length from the upper and lower center lines of the opening portion 26 of the mouth plate 2 2 to the upper end of the dust bag 20 (the upper length of the dust bag 20) L2, which is about i〇mm or so. That is, it has L1. <L2 relationship. However, it is also possible for L14L2. The length from the upper and lower center lines of the opening portion 26 of the mouth plate 22 to the upper end of the mouth plate 22 is substantially equal to the length ' from the upper and lower center lines of the opening portion 26 of the mouth plate 2 to the lower end of the mouth plate 2 2 . Therefore, the center of the vertical direction of the mouth plate 22 substantially coincides with the center of the vertical direction of the opening portion 26. In this manner, the lower end of the dust bag 20 is not joined, and is detachably held by the clip-16-201143703 27, so that the user can collect the dust collected in the dust bag 2 from the dust bag 20. The lower end opening is discharged, and by gripping the lower end of the dust bag 20 with the clip 27, the dust bag 20 can be reused. Therefore, the resources of the dust bag 20 can be saved to avoid waste. Since the clip 27 is disposed on the surface opposite to the intake port of the electric blower 9, i.e., the inner surface (back surface) of the dust bag 20, it can be avoided that the clip 27 hinders the inhalation or causes the airflow to be disordered. As the use time becomes longer, fine dust adheres to the bag member 21, and the air permeability of the bag member 21 is lowered, so that the number of reuse of the dust bag 20 is preferably two's or so. Further, since the clip 27 is disposed on the surface opposite to the intake port of the electric blower 9, that is, the inner surface (back surface) of the dust collecting bag 20, it can be avoided that the clip 27 hinders the inhalation or causes the airflow to be disordered. . Next, Fig. 5 is an external perspective view of the clip 27 of the embodiment of the present invention. Fig. 5(a) shows a perspective view seen from one of the clips 27, and Fig. 5(b) is a perspective view showing the other side of the opposite side of the clip 27. Fig. 6 is a perspective view showing the appearance of the dust collecting bag 20 of the embodiment of the invention. Fig. 6 is a view showing a state in which the clip 27 is attached to the dust bag 20 without being held. The clip 27 is preferably made of synthetic resin or metal. The clip 27 is provided with a rod-shaped upper wrist member 41 and a rod-shaped lower wrist member 42. The lengths of the upper wrist member 41 and the lower wrist member 42 are longer than the length of the lower end portion of the dust bag 20 (the bag member 21) in the left-right direction. Therefore, the length of the clip 27 is also longer than the length of the lower end portion of the dust bag 20 (the bag member 21) in the left-right direction. The width of the upper wrist member 41 and the lower wrist member 42 is smaller than the folding width of the lower end portion of the dust collecting bag 20 of -17-201143703. However, the width ' of the upper wrist member 4i and the lower wrist member 42 may be 'equal or larger than the folding width of the lower end portion of the dust bag 20'. The upper end of the upper wrist member 41 is linear, and the other end is folded into a substantially L. Glyph. The portion of the upper wrist member 41 that is bent into a substantially L shape is rotatably coupled to the other end of the lower wrist member 42 (coupling portion 43). At one end of the lower wrist member 42, a stopper 45 (coupling portion 46) having a substantially gate-shaped cross section is rotatably coupled. The stopper 45, when the upper wrist member 41 is closed with respect to the lower wrist member 42, holds one end of the upper wrist member 41 inside the substantially gate-shaped shape, and has a function of maintaining the closed state. Instead of the stopper 44, a wheel rubber can also be used. Instead of the stopper 44, an elastic member such as a spring for biasing the upper wrist member 41 and the lower wrist member 42 in the relative closing direction may be provided in the vicinity of the joint portion 43. At the intermediate portion of one end and the other end of the lower wrist member 42, a stopper 44 having a substantially gate-shaped cross section is joined. As shown in Fig. 6, the stopper 44 has a function for preventing the lower end of the dust bag 20 from being displaced. That is, the stopper 44 prevents the clip 27 from being displaced or peeled off by sandwiching the lower end portion of the dust bag 20 by the clip 27. Further, the stopper 44 allows the user to easily position when the clip is attached to the lower end portion of the dust bag 20. That is, by attaching the clip 27 to the lower end side of the dust bag 20, the clip 27 is prevented from being displaced from the lower end portion of the dust bag 20 and is detached, and conversely, the clip 27 is attached to the dust bag. The center side of 20 can prevent the dust collecting capacity in the dust collecting bag 20 from becoming small. The cross section of the stopper 44 may be a U-shape instead of a U-shape. -18-201143703 The movable member 44 may not be extended along the lower wrist member 42 but may be partially protruded. However, the stopper 44 is not an essential configuration 'No. One or both of the opposing faces of the upper wrist member 41 and the lower wrist member 42 and the opposing faces of the lower wrist member 42 and the upper wrist member 41 may also form a flexible rubber having a high coefficient of friction such as rubber. Deformed component. With this member, the state in which the lower end portion of the dust bag 20 is held by the clip 27 can prevent the clip 27 from being displaced or dropped. Further, the lower end portion of the dust collecting bag 20 is surely closed by the elastic force of the member, and dust can be prevented from being sucked from the lower end of the dust collecting bag 20. In the clip 27 of the present embodiment, when the lower end portion of the dust bag 20 is completely sandwiched in the left-right direction, the number of times of folding of the lower end portion of the dust bag 20 may be zero. In other words, in the state where the lower end of the dust bag 2 is opened, the opening is closed by the clip 27, and the opening is closed. Conversely, if the lower end portion of the dust bag 20 is folded back more than once, the lower side portion of the dust bag 20 may not be fully sandwiched in the left and right direction, and the dust bag may be folded. Partial closure of the lower end portion of 20 is also possible. When at least 50% or more of the lower end portion of the dust bag 20 is sandwiched, the dust is not sucked from the lower end opening of the dust bag 20. For example, instead of the clip 27, a round clip or a Z-shaped clip can be used, and the clip can be rotated. Fig. 7 is a side view showing a state in which the stacking bag 20 of the embodiment of the present invention is bundled. The bag member 2 1, folded out: with respect to the central portion of the bag member 21 of the adhesive port 22, the upper side portion of the bag member 21 without the adhesive interface plate 22, and the lower portion of the bag member 21 without the adhesive interface plate 22 - 19- 201143703 Side section. That is to fold twice. It is preferable to fold the bag member 21 first and then fold the lower side portion of the bag member 21. That is, the lower side portion of the piece 21, that is, the clip 27 is located outside. When it is put into a box or a bag, etc., the bag member is folded in a state of being folded without being toughened, and is attached to the dust collecting body. However, it is also possible to separate the bag 20 from the clip 27 to place a sub-bag or the like. In this case, the clip 27 is attached to the dust collecting ridge end portion, and the lower side portion of the bag member 21 is folded again, and is preferably attached to the dust collecting portion 5. By placing the lower side clip 27 of the bag member 21 on the outside, when the dust bag 20 sucks in dust and expands on the upper side portion of the bag member 21, the portion of the lower side portion of the bag member 21 in which the clip 27 is placed is opened first. . By letting L1 <L2, the opened portion is short, and when the dust bag 20 inhales the dust, it is easy to open. However, in the dust collecting portion 5, the dust collecting bag 20 is swollen, and the upper side portion of the bag member 21 is opened toward the rear side of the bag member 21, and the upper portion of the bag member 21 is inward (expanded). The lower side portion of the bag member 21 is opened toward the rear side with respect to the bag structure and the central portion, and the lower side portion of the bag member 21 is not opened (no expansion) and is still closed. By keeping the inside of the lower portion of the ridge unopened and keeping closed, the tension caused by almost no expansion is applied to the grip portion of the clip 27 (returning, so even if the grip of the clip 27 is slightly relaxed, it can be prevented: The dust bag 20 is detached, and the dust leaks from the lower end of the dust bag 20 to the upper side. The bag 21 is in the state 21, and the portion 5 is preferably inserted into the box 20 to be subdivided. In other words, when the first expansion is performed, the central part of the state will be inflated, and the part is also opened in the inner part of the cloth 21, and the other part is 2, because there is a violent violent violent circumcision. Fig. 3 is a view showing the dimensional relationship between the inside of the dust collecting portion 5 of the cleaner main body 2 and the dust collecting bag 20. The center in the vertical direction of the inflow port 30 of the cleaner body 2 is the center line (the one-point broken line in Fig. 3), and is the center line of the opening portion 26 of the dust collecting bag 20 (the point in Fig. 4(b) is broken. The fold line) is roughly the same. On the other hand, the center line of the inflow port 30 (the one-point broken line in FIG. 3) does not match the center line of the rotating shaft of the electric blower 9 (the one-point broken line in FIG. 3), and the rotating shaft of the electric blower 9 The center line is on the upper side. The suction port of the electric blower 9 is located slightly above the inlet 30 of the cleaner body 2. Therefore, the air that has flowed in from the inflow port 30 flows slightly upward and is sucked from the intake port of the electric blower 9. The lid portion 8 formed on the upper surface of the dust collecting portion 5 is inclined so as to be located on the lower side from the rear side toward the front side. On the other hand, in the intermediate portion in the front-rear direction of the bottom surface of the collecting portion 5, the caster mounting portion 47' for attaching the guide wheel 40 to the bottom surface of the cleaner body 2 protrudes toward the inside of the dust collecting portion 5, and if When the caster attachment portion 47 is removed, the bottom surface of the dust collecting portion 5 and the front-rear direction of the cleaner body 2 substantially coincide with each other in the horizontal direction. The caster mounting portion 47 is not an essential configuration. The height from the front bottom surface of the dust collecting portion 5 to the center line of the inflow port 30 (the lower portion height of the front portion of the dust collecting portion 5) is Η1, from the center line of the inflow port 30 to the front portion of the dust collecting portion 5 The height (the upper portion of the front portion of the dust collecting portion 5) is Η 2, and the height from the bottom surface of the rear portion of the dust collecting portion 5 to the center line of the inflow port 30 (the lower portion height of the rear portion of the dust collecting portion 5) is Η3. The height from the center line of the inflow port 30 to the upper portion of the rear portion of the dust collecting portion 5 (the upper height of the rear portion of the dust collecting portion-21 - 201143703 5) is H4, and the height of the front portion of the dust collecting portion 5 is (HI) + H2 ) indicates that the height of the rear portion of the dust collecting portion 5 is represented by (H3 + H4 ). The bottom surface (lower surface) of the dust collecting portion 5 substantially coincides with the front-rear direction of the cleaner body 2, that is, the horizontal direction, so Η 1 and H3. The upper surface of the dust collecting portion 5 is inclined so as to become lower toward the front. < Η 4. Therefore’ (Η1+Η2) < (Η3+Η4). If the depth of the dust collecting portion 5 in the front-rear direction is W, then W < (Η1 + Η2). That is, the depth in the front-rear direction of the inner portion of the dust collecting portion 5 is smaller than the height inside the dust collecting portion 5. Further, an inflow port 30 is formed below the center of the dust collecting portion 5 in the vertical direction. When the inflow port 30 is used as a reference, the upper side space of the dust collecting portion 5 is wide, and the lower side space is narrow. That is, the center line of the inflow port 30 is located on the lower side with respect to the center of the dust collecting portion 5 in the vertical direction. Therefore, Η 1 < H2, H3 < Η 4. As shown in Fig. 3, when the dust bag 20 is inflated in the dust collecting portion 5, the outer surface of the inner surface (back surface) of the dust collecting bag 20 facing the opening portion 26 is in contact with the dust collecting portion 5 The inner surface of the inner face (back) forms the front of the protective filter 18. Therefore, the depth of the dust collecting bag 20 in the front-rear direction when the dust collecting bag 20 is swollen is the same as or larger than the depth W in the front-rear direction in the dust collecting portion 5. The outer surface of the bottom surface (lower surface) of the dust bag 20 is almost inflated in the lower portion of the bag member 21, and is in contact with the inner surface of the bottom surface (lower surface) of the dust collecting portion 5. This is because air is easily allowed to flow in the central portion of the bag member 21, so that the central portion of the bag member 21 first expands, and air is less likely to flow into the lower portion of the bag member 21, by the central portion of the bag member 21. The expansion hinders the expansion of the underside portion of the bag member 2! -22- 201143703. On the other hand, in the upper side portion of the bag member 21, the upper side space of the dust collecting portion 5 is wide, so that the expansion of the central portion of the bag member 21 does not hinder the expansion of the upper side portion of the bag member 21, so that the bag member 2 1 The upper side portion can expand. Therefore, the height from the bottom surface of the dust collecting bag 20 to the center line of the opening portion 26 when the dust collecting bag 2 is inflated is equal to or larger than the lower portions HI and H3 of the dust collecting portion 5. The lower length L1 of the folded state of the dust bag 20 is L1 > H1, L1 > H3. The clip 27 is in contact with a caster attachment portion 47 formed by partially forming the bottom surface of the dust collecting portion 5. On the other hand, the outer surface of the upper surface of the dust collecting portion 20 does not contact the inner surface of the upper surface of the dust collecting portion 5. That is, even if the dust bag 2 is inflated 'the height from the center line of the opening portion 26 to the upper surface of the collecting bag 20 is smaller than the upper heights H2 and H4 of the dust collecting portion 5. The center of the dust collecting portion 5 in the vertical direction is located on the lower side, and the depth in the front-rear direction of the dust collecting portion 5 is smaller than the height in the vertical direction, and the upper surface of the dust collecting bag 20 is opened. On the other hand, the lower surface of the dust collecting bag 20 is in a state of being marginal (the inside of the lower side portion of the bag member 21 is hardly expanded). That is, the tension applied to the lower surface of the dust collecting bag 20 Since the tension applied to the upper surface of the dust collecting bag 20 is smaller, even if the clamping of the clip 27 is slightly relaxed, it is possible to prevent the clip 27 from coming off the dust collecting bag 20 and the dust leaking from the lower surface of the dust collecting bag 20. The outer surface of the upper surface of the dust bag 20 may be in contact with the inner surface of the upper surface of the dust collecting portion 5 as long as the lower surface of the dust bag 2 is in a sufficient state. By using the inflow port 30 as a reference, the clip 2 can be attached to the narrow side of the upper and lower spaces of the dust collecting portion 5. Therefore, for example, the inflow port 3 is used as the base 23-201143703, and the upper space of the dust collecting portion is used. When the space on the lower side is narrow, the lower end of the bag 20 is joined at any time by an adhesive or the like, and the upper end of the clip 20 may be held by the clip 27. [Embodiment 2] Next, another embodiment of the dust bag 20 will be described. An external perspective view of the dust collecting bag of the second embodiment of the ninth invention. The folded portion 24 is folded back twice in the same manner as the folded portion 23, and is formed by bonding (joining member). That is, the upper end of the lower bag member 21 of the bag member 21 is similarly closed at any time. The cutting line 48 along the left-right direction is formed (printed) to a level of several mm above the folded portion 24 of the bag member 2 1 . In the vicinity of the 4 8 (upper or lower side), the "cutting line" is printed. The surface of the bag member 21 is more than 20 mm above the cut line 48, and a folding line 49 along the left-right direction is formed (printed), and the surface of the folding line 49 is 20 mm higher than the upper side, and is formed (printed left and right direction). The folding line 50. The folding line 49, the folding line 50 (upper or lower side, preferably the text of the "folding line" between the folding line 49 and the folding line 50 is preferred. The cutting line 48 or The folding line stacking wire 50 may be replaced by a stamper, and the recessed portion may be added by a stamper. Instead of the folding line 49 and the folding line 50, two of them may be formed to form one, or none of them may be used. When the cutting line 4 8 is formed, when the user removes the dust collecting bag 20 angstroms and the dust collecting bag 20 is reused, the dust collecting bag can be used as the adhesive end by scissors. , with the surface of the surface of the cut line and the vicinity of the edge of the text, the print 49, the fold type can also be used, the dust inside is easy to distinguish. 24-201143703 50, dust bag will be collected to identify the cutting position. By forming the folding line 49 and the folding line 50, the user can remove the dust in the dust collecting bag 20, and the dust collecting bag 20 can be easily cut out after being cut with scissors. In this way, the upper and lower ends of the dust bag 20 are joined, and the lower portion of the dust bag 20 forms a cut line 48 or a fold line 49, and is folded; the user can freely choose: the dust bag 20 is no longer used and will be discarded. The manner of use and the manner in which the dust in the dust bag 20 is removed from the dust bag 20 is used.
