本發明係有關於一種吸塵器用吸嘴，用於藉由一抽吸氣流吸走地面上之污物及/或灰塵，特別是粗粒及微粒，具有一用於導引該抽吸氣流的抽吸道、一包含一上殼的殼體、一抽吸腔及一密封唇，其中該抽吸腔構建於該上殼下方，該抽吸道與該抽吸腔連通，該密封唇至少部分地界定該抽吸腔。 The invention relates to a vacuum cleaner nozzle for sucking dirt and/or dust on the ground, in particular coarse particles and particles, by a suction airflow, and has a pump for guiding the suction airflow. a suction channel, a housing including an upper casing, a suction chamber and a sealing lip, wherein the suction chamber is formed below the upper casing, the suction passage is in communication with the suction chamber, the sealing lip is at least partially The suction chamber is defined.
吸塵器用吸嘴，亦稱附件或噴嘴或者視具體用途而亦稱硬地吸嘴或電動刷，已在實踐中廣為人知。具有此類吸嘴之吸塵器通常具有一基本殼體，以便容置用於產生抽吸氣流之電動抽風機馬達。吸嘴通常透過一可撓軟管及/或一操作管與吸塵器流體密封連接。就抽吸機器人而言，吸嘴通常整合在基本殼體中。吸嘴可透過刷毛及/或彈性密封唇放置在地面上。藉由抽吸氣流將自待處理即待清理之地面吸走之灰塵顆粒及/或污物顆粒聚集於通常設置在基本殼體中之集塵室中的濾塵袋。 Vacuum cleaner nozzles, also known as accessories or nozzles or hard nozzles or electric brushes, depending on the particular application, are well known in practice. A vacuum cleaner having such a nozzle typically has a basic housing for receiving an electric blower motor for generating a suction airflow. The nozzle is typically fluidly sealed to the vacuum cleaner via a flexible hose and/or an operating tube. In the case of a suction robot, the nozzle is usually integrated in the basic housing. The nozzle can be placed on the ground through the bristles and/or the elastic sealing lip. The dust particles and/or dirt particles sucked away from the floor to be treated, which is to be cleaned, are collected by a suction air flow to a dust filter bag which is usually disposed in a dust collecting chamber in the basic casing.
需要自地面吸收之污物或灰塵根據其粒度而分為粗粒與微粒。一方面揭露有為吸收粗粒而最佳化之吸嘴，亦存在用來特別有效地吸收微粒的吸嘴。舉例而言，傳統硬地吸嘴通常並非為吸走較粗污物而設計。亦存在例如藉由腳踏鍵而在吸收粗粒與吸收微粒間進行手動切換的吸嘴。為此，藉由該腳踏鍵例如可將一刷毛條伸出吸嘴，該刷毛條增大吸嘴與地面的距離，以便更好地吸收或吸取粗粒。因此，先前技術所揭露之吸嘴一般總是僅能滿足若干相互衝突之要求中的一項，亦即，要麼實施粗粒吸收，要麼實施微粒吸收，或者必須由使用者手動地在此等不同工作模式間進行切換。 Contaminants or dust that need to be absorbed from the ground are classified into coarse particles and fine particles according to their particle size. On the one hand, there are disclosed nozzles which are optimized for absorbing coarse particles, and there are also nozzles for particularly efficiently absorbing particles. For example, conventional hard nozzles are generally not designed to absorb coarser dirt. There is also a nozzle that manually switches between absorbing coarse particles and absorbing particles by, for example, a foot button. For this purpose, for example, a bristles can be extended from the nozzle by means of the foot button, which increases the distance of the nozzle from the ground in order to better absorb or absorb the coarse particles. Therefore, the nozzles disclosed in the prior art generally can only meet one of several conflicting requirements, that is, either perform coarse particle absorption or perform particle absorption, or must be manually different by the user. Switch between working modes.
有鑒於此，本發明之目的在於提供一種吸嘴，其針對粗粒及微粒皆具良好的抽吸功率。 In view of the above, it is an object of the present invention to provide a nozzle which has good suction power for both coarse particles and fine particles.
本發明用以達成上述目的之解決方案為請求項1之主題。較佳改良方案參閱附屬項。 The solution of the present invention to achieve the above object is the subject matter of claim 1. See the attached item for a better improvement.
本發明基於一種吸塵器用吸嘴，用於藉由一抽吸氣流吸走地面上之污物及/或灰塵，特別是粗粒及微粒，具有一用於導引該抽吸氣流的抽吸道、一包含一上殼的殼體、一抽吸腔及一密封唇，其中該抽吸腔構建於該上殼下方，該抽吸道與該抽吸腔連通，該密封唇至少部分地界定該抽吸腔，其特徵在於，該密封唇具有多個用來強化之彼此間隔設置之加固件。 The invention is based on a nozzle for a vacuum cleaner for sucking dirt and/or dust on the ground, in particular coarse particles and particles, by a suction airflow, having a suction channel for guiding the suction airflow a housing comprising an upper casing, a suction chamber and a sealing lip, wherein the suction chamber is formed below the upper casing, the suction passage is in communication with the suction chamber, the sealing lip at least partially defining the The suction chamber is characterized in that the sealing lip has a plurality of reinforcing members spaced apart from each other for reinforcement.
因此，本發明之關鍵點在於，設有多個將該密封唇強化之加固件，其中在該等加固件之間設有該密封唇之非強化區域。該密封唇之強化可指直接強化或間接強化，下文將對此進行詳細說明。亦即，該密封唇本身具有該等強化部(即被直接強化)，或者設有不同於該密封唇之附加部件，其將該密封唇間接強化。 Accordingly, a key point of the present invention is the provision of a plurality of stiffeners for reinforcing the sealing lip, wherein a non-reinforced region of the sealing lip is provided between the reinforcing members. The strengthening of the sealing lip may refer to direct strengthening or indirect strengthening, which will be described in detail below. That is, the sealing lip itself has such reinforcements (ie, is directly reinforced) or is provided with additional components that are different from the sealing lip, which indirectly strengthens the sealing lip.
此外，下文如此地選擇用於對該吸嘴之部件的佈置方案進行描述的術語，從而建立在該吸嘴之當其在工作模式下處於地面抽吸之狀態時的位置及定向上。亦即，該上殼在工作過程中朝上方界定該抽吸腔。 Furthermore, the terms used to describe the arrangement of the components of the nozzle are selected as follows, thereby establishing the position and orientation of the nozzle when it is in the state of ground suction in the operating mode. That is, the upper casing defines the suction chamber upwardly during operation.
根據本發明的一種較佳改良方案，該密封唇在該吸嘴之進給方向上視之朝前方界定該抽吸腔。亦即，採用此種改良方案之吸嘴的密封唇構成該抽吸腔的前界限，換言之，該密封唇就該吸嘴之工作模式下的進給方向而言設置在前部。 According to a preferred refinement of the invention, the sealing lip defines the suction chamber in the direction of the feed of the nozzle. That is, the sealing lip of the nozzle with such a modification constitutes the front limit of the suction chamber, in other words, the sealing lip is arranged at the front in terms of the feed direction in the operating mode of the nozzle.
在此情況下，該等用於強化該密封唇之彼此間隔設置之加固件如此地進行作用，使得抽吸氣流之流速在密封唇之加固區域大於未加固之情形。亦即，未加固之密封唇更容易因沿流動方向之抽吸氣流而在流動橫截面增大的情況下發生變形，從而降低流速。將密封唇加固會降低滲漏率，從而提高抽吸功率。如此便能改善微粒吸收，因為此舉進一步降低了抽吸腔內的壓力。此外，該等用於強化密封唇之加固件係彼此間隔設置，如此便能提高微粒吸收的抽吸功率，而毋需對良好的粗粒吸收造成影響。亦即， 在該等加固件之間的間隔區域內即在該密封唇之不含加固件的區域內，粗粒仍能輕易地到達位於密封唇後面之吸入口(Saugmund)下方，進而能被吸收。 In this case, the reinforcing members arranged to reinforce the sealing lips are arranged such that the flow rate of the suction air flow is greater in the reinforcing region of the sealing lip than in the unreinforced state. That is, the unreinforced sealing lip is more susceptible to deformation due to the increased flow cross section due to the suction flow in the flow direction, thereby reducing the flow rate. Reinforcing the sealing lip reduces the leakage rate and thus the pumping power. This improves particle absorption because it further reduces the pressure in the suction chamber. In addition, the reinforcing members for reinforcing the sealing lips are spaced apart from each other, so that the suction power absorbed by the particles can be increased without affecting the good coarse particle absorption. that is, In the region of the gap between the stiffeners, i.e. in the region of the sealing lip which is free of reinforcement, the coarse particles can still easily reach below the suction opening behind the sealing lip and can be absorbed.
就提高粗粒吸收之態樣而言，根據本發明的一種較佳改良方案，該等加固件至少部分地如此構建，從而在該密封唇的寬度上實現不同強度的強化部。根據該方案，例如可防止在該密封唇之未加固區域與加固區域間發生急劇的剛度變化。特定言之，該密封唇之剛度大小遵循某個函數，如樣條函數、正弦函數或拋物線。如此便能增大供粗粒良好地經由吸嘴進入抽吸腔的區域，從而提高粗粒吸收。由於該等原本就設置的加固件，因而抽吸腔內的負壓仍較高，故微粒吸收亦有所提高。 In a preferred refinement of the invention, in accordance with a preferred refinement of the invention, the reinforcements are at least partially constructed such that reinforcements of different strengths are realized over the width of the sealing lip. According to this aspect, for example, a sharp change in stiffness between the unreinforced region of the sealing lip and the reinforcing region can be prevented. In particular, the stiffness of the sealing lip follows a function such as a spline function, a sine function, or a parabola. This makes it possible to increase the area where the coarse particles enter the suction chamber well through the suction nozzle, thereby increasing the coarse particle absorption. Due to the originally provided reinforcing members, the negative pressure in the suction chamber is still high, so the absorption of particles is also improved.
該等用於強化該密封唇之加固件具有不同的構建方案。特定言之，該等加固件如前所述可將該密封唇間接強化或直接強化。有鑒於此，根據本發明的一種較佳改良方案，該等加固件至少部分地由若干獨立於該密封唇之支撐元件構成，該等支撐元件在該吸嘴之進給方向上自該抽吸腔內部朝外地對該密封唇進行支撐。根據本發明之此前所描述的較佳改良方案，該密封唇在該吸嘴之進給方向上朝前方界定該抽吸腔，則在此情況下係自後部支撐該等密封唇。該密封唇之該等間接強化部之作用在於，與不設支撐元件之情形相比，該等密封唇之被該等支撐元件所支撐之區域沿抽吸氣流發生變形的程度顯著降低，從而降低前述之滲漏率並提高抽吸腔內的負壓。 These reinforcements for reinforcing the sealing lip have different construction schemes. In particular, the stiffeners may indirectly strengthen or directly strengthen the sealing lip as previously described. In view of the above, according to a preferred refinement of the invention, the reinforcements are at least partially formed by a plurality of support elements which are independent of the sealing lip, the support elements being sucked in the feed direction of the nozzle The sealing lip is supported outwardly inside the cavity. According to a preferred refinement of the invention described above, the sealing lip defines the suction chamber towards the front in the feed direction of the nozzle, in which case the sealing lips are supported from the rear. The indirect strengthening portions of the sealing lip function to significantly reduce the extent to which the sealing lips are deformed by the suction airflow as compared to the case where no supporting members are provided, thereby reducing the degree of deformation of the sealing lip The aforementioned leakage rate increases the negative pressure in the suction chamber.
可以不同方式選擇該等支撐元件的大小。根據本發明的一種較佳改良方案，該等支撐元件之高度，即其在該吸嘴之工作狀態下的豎向延伸度，係如此地選擇，使得在吸嘴放置在地面上時，該等支撐元件的下端與地面間隔一定距離。儘管將支撐元件之下端放置在地面上會進一步降低抽吸氣流穿過密封唇下方的滲漏率，但即使在支撐元件之末端與地面間隔設置的情況下，亦能顯著提高抽吸腔內的負壓，而不會造成地面受損或者因吸嘴移動至地面時之摩擦噪音或刮擦噪音而造成影響。 The size of the support elements can be selected in different ways. According to a preferred refinement of the invention, the height of the support elements, ie their vertical extent in the operating state of the nozzle, is selected such that when the nozzle is placed on the ground, The lower end of the support member is spaced a distance from the ground. Although placing the lower end of the support member on the ground further reduces the leakage rate of the suction airflow through the underside of the sealing lip, even in the case where the end of the support member is spaced from the ground, the suction chamber can be significantly increased. Negative pressure without causing damage to the ground or frictional noise or scratching noise when the nozzle moves to the ground.
該等支撐元件可固定在該吸嘴的不同部件上。該等支撐元件較佳與該上殼連接。尤佳地，該等支撐元件與該上殼成一體。此點除提供非常穩定之構造外，亦能實現吸嘴之簡單且有效的製造過程。 The support elements can be attached to different parts of the nozzle. The support members are preferably connected to the upper casing. More preferably, the support elements are integral with the upper casing. In addition to providing a very stable construction, this also enables a simple and efficient manufacturing process of the nozzle.
除前述之間接強化外，本發明亦包括直接強化之方案。故根據本發明的一種相應之較佳改良方案，該等加固件至少部分地由該密封唇的若干加強件構成。亦即，該密封唇本身沿其寬度具不同剛度，從而形成該密封唇被加固的若干區域，該等區域被該密封唇未被如此地強化的區域隔開。 In addition to the aforementioned indirect reinforcement, the present invention also includes a direct reinforcement scheme. According to a correspondingly preferred refinement of the invention, the reinforcements are at least partially formed by a plurality of reinforcement members of the sealing lip. That is, the sealing lip itself has a different stiffness along its width, thereby forming regions where the sealing lip is reinforced, the regions being separated by the region of the sealing lip that is not so reinforced.
因而尤佳地，該等加強件由該密封唇的若干材料增厚部構成。作為替代或補充方案，該密封唇可由具不同剛度的不同材料製成。此外亦需提及的是，根據本發明的一種較佳改良方案，亦可將直接強化之方案與間接強化之方案相結合，亦即，根據此種解決方案，該密封唇既配設 有至少一支撐元件，本身又具有至少一加強件。 It is therefore particularly preferred that the stiffeners are formed by a plurality of material thickenings of the sealing lip. Alternatively or additionally, the sealing lip can be made of different materials having different stiffnesses. In addition, it should be mentioned that, according to a preferred refinement of the invention, the direct reinforcement scheme can also be combined with the indirect reinforcement scheme, that is to say, according to the solution, the sealing lip is provided There is at least one support element which in turn has at least one reinforcement member.
就本發明之吸嘴而言，透過以下方式來實現良好的粗粒吸收：該等用於強化密封唇之加固件係彼此間隔設置。亦即，在該等加固件之間，粗粒仍能輕易地在吸嘴下方進入抽吸腔，進而能被吸收。為進一步提高粗粒吸收，根據一種較佳改良方案，該密封唇具有多個縫隙。本發明發現，該等縫隙僅略微降低負壓及微粒吸收，但能顯著改善粗粒吸收，因為如此一來，粗粒便能更容易地到達吸嘴下方從而進入抽吸腔。 With regard to the nozzle of the present invention, good coarse particle absorption is achieved by the fact that the reinforcing members for reinforcing the sealing lip are spaced apart from each other. That is, between the reinforcements, the coarse particles can still easily enter the suction chamber below the suction nozzle and can be absorbed. In order to further increase the coarse particle absorption, according to a preferred refinement, the sealing lip has a plurality of slits. The present inventors have found that the gaps only slightly reduce the negative pressure and particulate absorption, but significantly improve the coarse particle absorption, as the coarse particles can more easily reach the suction nozzle and enter the suction chamber.
其中，該等縫隙之長度原則上總是相等。根據本發明的一種較佳改良方案，該等縫隙之長度在該密封唇的寬度上有所變化。如此便能(例如)與該密封唇之加固件的佈置方案相匹配。根據該方案尤佳地，該等縫隙的至少一部分，較佳所有縫隙，設置在該密封唇之該等加固件以外的區域內。此點既適用於縫隙長度總是相等的情形，又適用於縫隙長度在密封唇寬度上有所變化的情形。 The lengths of the slits are always equal in principle. According to a preferred refinement of the invention, the length of the slits varies over the width of the sealing lip. This makes it possible, for example, to match the arrangement of the sealing lip of the sealing lip. More preferably, according to the solution, at least a portion of the slits, preferably all of the slits, are disposed in regions other than the stiffeners of the sealing lip. This applies both to the case where the length of the gap is always equal and to the case where the length of the slit varies over the width of the lip.
此外在該吸嘴之工作狀態下視之，該等縫隙原則上可傾斜延伸，即就密封唇之表面而言與垂線成一定角度。根據一種較佳改良方案，該等縫隙豎向或大體豎向延伸。此外，該等縫隙之長度較佳為5mm至15mm，進一步較佳為8mm至12mm，尤佳為9mm至11mm。此外在為本發明之吸嘴定尺寸方面，該等加固件之寬度較佳小於等於62mm。此外，該等加固件之間距尤佳為大於等於20mm。 In addition, in the operating state of the nozzle, the gaps can in principle be extended obliquely, that is to say at an angle to the perpendicular to the surface of the sealing lip. According to a preferred refinement, the slits extend vertically or substantially vertically. Further, the length of the slits is preferably from 5 mm to 15 mm, further preferably from 8 mm to 12 mm, and particularly preferably from 9 mm to 11 mm. Further, in terms of sizing the nozzle of the present invention, the width of the reinforcing members is preferably 62 mm or less. In addition, the distance between the reinforcing members is preferably 20 mm or more.
本文所描述之吸嘴較佳係指硬地吸嘴或電動 刷。硬地吸嘴適於對硬地面，如地磚或木地板，進行抽吸，由於待抽吸之地表面非常平滑，故硬地吸嘴能實現高強度清理。電動刷一般配設有一較佳電驅動或渦輪驅動的刷子，其位於抽吸腔內並對待抽吸地面進行刷理。此類刷子將更多的污物與地面分離，再利用抽吸氣流吸收該污物並將其吸走。 The nozzle described herein preferably refers to a hard nozzle or electric brush. The hard nozzle is suitable for suctioning hard floors such as floor tiles or wooden floors. Since the surface to be sucked is very smooth, the hard nozzle can achieve high strength cleaning. The electric brush is typically provided with a preferably electrically driven or turbine driven brush that is positioned within the suction chamber and that is to be pumped to the ground. Such brushes separate more dirt from the ground and then absorb the dirt with a suction stream and suck it away.
根據本發明的一種較佳改良方案，設有一第二密封唇，其在該吸嘴之進給方向上朝後方界定該抽吸腔，其中該第二密封唇同樣具有多個用來強化之彼此間隔設置之加固件。特定言之，此種第二密封唇較佳設置在以下情形下：該吸嘴係電動刷。此外，此前就該第一密封唇而言所描述的較佳改良方案原則上亦適用於該第二密封唇。 According to a preferred refinement of the invention, a second sealing lip is provided which delimits the suction chamber in the feed direction of the nozzle, wherein the second sealing lip likewise has a plurality of reinforcing surfaces for reinforcement The firmware for the interval setting. In particular, such a second sealing lip is preferably disposed in the following situation: the nozzle is an electric brush. Furthermore, the preferred embodiment described above with regard to the first sealing lip also applies in principle to the second sealing lip.
根據本發明的另一較佳改良方案，該抽吸腔構建為在至少一側上，較佳在兩側上至少局部曝露之橫向於該吸嘴之進給方向延伸的隧道。此點在該吸嘴為電動刷時係尤佳之選。該隧道在至少一側上側向曝露，如此便能不僅在吸嘴下方進行微粒吸收，即在該隧道所形成之抽吸腔中進行微粒吸收，還能在吸嘴以外之區域內，即在該隧道側向之至少局部曝露之處，進行微粒吸收。與該吸嘴之隧道所形成之抽吸腔的物理寬度相比，上述方案可增大在地面抽吸過程中用吸嘴實施微粒去除的有效寬度。亦即，根據本發明的此種較佳改良方案，實際上亦在吸嘴附近的區域內，即在該隧道朝外曝露之處，將微粒吸走。 According to a further preferred refinement of the invention, the suction chamber is constructed as a tunnel extending on at least one side, preferably at least partially exposed on both sides, transverse to the feed direction of the nozzle. This is especially desirable when the nozzle is a power brush. The tunnel is exposed laterally on at least one side, so that not only the absorption of particles under the nozzle, that is, the absorption of particles in the suction chamber formed by the tunnel, but also in the region other than the nozzle, that is, Partial absorption of the tunnel is carried out at least partially in the lateral direction. The above solution can increase the effective width of the particle removal by the nozzle during the ground suction process as compared to the physical width of the suction chamber formed by the tunnel of the nozzle. That is, according to this preferred refinement of the invention, the particles are actually sucked away in the vicinity of the nozzle, i.e. where the tunnel is exposed outwards.

FIG. 3 is a schematic view of a sealing lip according to another preferred embodiment of the present invention; FIG. 4 is a bottom view of a nozzle constructed as an electric brush according to a preferred embodiment of the present invention; And Fig. 5 is a side view of the nozzle constructed as an electric brush shown in Fig. 4.
圖1以透視圖的形式示出本發明的一較佳實施例中之構建為硬地吸嘴的吸嘴1的底面。圖1所示吸嘴1與其在工作狀態下之位置相反，即底面朝上。吸嘴1具有上殼2，該上殼中設有一渾圓形抽吸道口3。自抽吸道口3出發，吸嘴1之抽吸道過渡為一未進一步繪示之抽吸管。 Figure 1 shows, in perspective view, the underside of a nozzle 1 constructed as a hard suction nozzle in a preferred embodiment of the invention. The nozzle 1 shown in Fig. 1 is in a position opposite to its working state, that is, the bottom surface faces upward. The suction nozzle 1 has an upper casing 2 in which a circular suction passage opening 3 is provided. Starting from the suction channel 3, the suction channel of the nozzle 1 transitions into a suction tube which is not further illustrated.
圖1中在上殼2上方，即在吸嘴1之工作狀態下在該上殼2下方，構建有一抽吸腔4，在吸嘴1之真正意義上之工作模式下的進給方向上視之，該抽吸腔朝前被一密封唇5界定。本文中之“前”此一名稱係指某個區域，其在抽吸工作模式下在吸嘴1之地面清理過程中表示前區域。 In Fig. 1, above the upper casing 2, i.e. under the upper casing 2 in the operating state of the suction nozzle 1, a suction chamber 4 is constructed, in the direction of the feed in the true sense of operation of the nozzle 1 The suction chamber is defined forward by a sealing lip 5. The term "front" in this context refers to an area that indicates the front area during the surface cleaning of the nozzle 1 in the suction mode of operation.
密封唇5在一側上配設有若干縫隙6，在另一側上 具有若干加固件7。該等加固件7與上殼2成一體且彼此間隔設置。該等加固件7之高度低於密封唇5之高度。亦即，當密封唇5在吸嘴1之工作過程中放置在待抽吸地面上時，該等加固件7與地面間隔一定距離。 The sealing lip 5 is provided with a plurality of slits 6 on one side and on the other side There are several reinforcements 7. The reinforcing members 7 are integral with the upper casing 2 and are spaced apart from each other. The height of the stiffeners 7 is lower than the height of the sealing lip 5. That is, when the sealing lip 5 is placed on the ground to be sucked during the operation of the suction nozzle 1, the reinforcing members 7 are spaced apart from the ground.
在該等加固件7彼此間隔一定距離的區域內，密封唇5配設有分別構建為一縫隙對的縫隙6。亦即，在每兩個加固件7之間的間隔區域內各設有兩個縫隙6。該大體呈三角形之抽吸腔4朝後及側向被一雙列刷毛8界定。 In the region where the stiffeners 7 are spaced apart from each other, the sealing lip 5 is provided with a slit 6 which is formed as a pair of slits, respectively. That is, two slits 6 are provided in each of the spacing regions between the two reinforcing members 7. The generally triangular suction chamber 4 is defined rearwardly and laterally by a double row of bristles 8.
自圖2可看出該等加固件7相對密封唇5之設置方案以及該等縫隙6在本發明的一較佳實施例中的分佈。如圖2所示，密封唇5在其兩側各被一加固件7界定。該等加固件7皆側向伸出密封唇5之末端。圖2中之定向與圖1中之定向相同。亦即，在抽吸刷之工作過程中，朝向地面之區域在圖2中同樣指向上方。 The arrangement of the stiffeners 7 relative to the sealing lip 5 and the distribution of the slits 6 in a preferred embodiment of the invention can be seen in Figure 2. As shown in Figure 2, the sealing lip 5 is bounded on each side by a stiffener 7. The stiffeners 7 project laterally beyond the end of the sealing lip 5. The orientation in Figure 2 is the same as the orientation in Figure 1. That is, during the operation of the suction brush, the area facing the ground is also pointed upward in FIG.
圖3示出密封唇5及用於強化該密封唇5之加固件7的一替代性實施方式。如圖3所示，縫隙6具有不同長度且並非僅設置在該等加固件7之間之間隔區域所界定的區域內。其中，該等加固件7不具圖2所示之平直形狀，而是呈彎曲形狀。如此便能對密封唇5進行沿該密封唇5之寬度有所變化的強化。 FIG. 3 shows an alternative embodiment of the sealing lip 5 and the reinforcement 7 for reinforcing the sealing lip 5. As shown in Figure 3, the slits 6 have different lengths and are not only disposed within the area defined by the spacing regions between the stiffeners 7. Among them, the reinforcing members 7 do not have the straight shape shown in FIG. 2, but have a curved shape. In this way, the sealing lip 5 can be reinforced with a variation along the width of the sealing lip 5.
此外，圖4示出本發明的一較佳實施例中之構建為電動刷的吸嘴10。該吸嘴10同樣被自底部示出且除一前密封唇5外亦具一後密封唇9，該等密封唇共同地對抽吸腔4之前部與後部進行界定。抽吸腔4中設有一刷子11，其可藉 由一未進一步繪示之電驅動裝置而橫向於吸嘴10之進給方向轉動，從而對待抽吸地面進行刷理，如此便能去除地面上的更多污物及灰塵。 Furthermore, Figure 4 shows a nozzle 10 constructed as an electric brush in a preferred embodiment of the invention. The nozzle 10 is likewise shown from the bottom and has a rear sealing lip 9 in addition to a front sealing lip 5 which collectively defines the front and rear portions of the suction chamber 4. a brush 11 is provided in the suction chamber 4, which can be borrowed It is rotated transversely to the feed direction of the nozzle 10 by an electric drive unit, not further illustrated, so that the ground to be sucked is brushed, so that more dirt and dust on the ground can be removed.
第一密封唇5及第二密封唇9二者各具多個用來強化之彼此間隔設置之加固件7。該等密封唇5、9以及加固件7的佈置方案原則上與圖2所示佈置方案相同，但加固件7之數目有所增大。此外，該等密封唇5、9配設有此處未繪示之若干縫隙，以便吸收粗粒，上文已作詳細說明。 The first sealing lip 5 and the second sealing lip 9 each have a plurality of reinforcing members 7 which are arranged to be spaced apart from one another. The arrangement of the sealing lips 5, 9 and the stiffener 7 is in principle identical to the arrangement shown in Figure 2, but the number of stiffeners 7 is increased. Furthermore, the sealing lips 5, 9 are provided with a number of slits not shown here in order to absorb the coarse particles, as explained in detail above.
如圖5所示，本實施例的另一實質之處在於，抽吸腔4構建為在兩側上局部曝露之橫向於吸嘴10之進給方向延伸的隧道。圖5並非如其他附圖般示出處於仰臥位的吸嘴10，而是示出該吸嘴10處於真正意義上之工作模式時的定向。亦即，吸嘴10以其底面放置在待抽吸地面上。如圖5所示，吸嘴10之殼體12在其朝向地面的一側上具有一側向孔口13。圖5在一側上示出此種情形；但該等孔口13係設置在吸嘴10的兩側上。 As shown in Fig. 5, another essential feature of the present embodiment is that the suction chamber 4 is constructed as a tunnel that is partially exposed on both sides and extends transversely to the feed direction of the nozzle 10. Figure 5 does not show the nozzle 10 in the supine position as shown in the other figures, but rather shows the orientation of the nozzle 10 when it is in the true working mode. That is, the suction nozzle 10 is placed with its bottom surface on the ground to be suctioned. As shown in Figure 5, the housing 12 of the nozzle 10 has a lateral opening 13 on its side facing the ground. Figure 5 shows this on one side; however, the apertures 13 are provided on both sides of the nozzle 10.
採用吸嘴10之殼體12的側向孔口13後，便能不僅在吸嘴10下方進行微粒吸收。確切言之，本發明之該較佳實施例中之吸嘴10在殼體12以外之區域內亦具抽吸效果。亦即，除在吸嘴10下方外，亦在吸嘴10以外，即吸嘴10側向之緊鄰吸嘴10之殼體12中之側向孔口13的區域內，吸收微粒。此舉可增大吸嘴10之有效抽吸寬度並能吸收更多微粒。 With the lateral opening 13 of the housing 12 of the nozzle 10, not only the absorption of particles under the nozzle 10 can be performed. Specifically, the nozzle 10 of the preferred embodiment of the present invention also has a suction effect in an area other than the housing 12. That is, in addition to the suction nozzle 10, particles are also absorbed outside the suction nozzle 10, i.e., the side of the suction nozzle 10 that is adjacent to the lateral opening 13 in the casing 12 of the suction nozzle 10. This increases the effective suction width of the nozzle 10 and absorbs more particles.
