Description

Die Erfindung betrifft ein Handreinigungsgerät, insbesondere eine Klobürste, mit einem Stiel sowie einem Bürstenkopf, wobei der Stiel und/oder der Bürstenkopf eine Hohlkammer zur Aufnahme eines Reinigungsmittels aufweisen, und wobei der Bürstenkopf über mindestens eine mit der Hohlkammer kommunizierende Öffnung verfügt, um das Reinigungsmittel über diese Öffnung abzugeben.The invention relates to a hand cleaning device, in particular a toilet brush, with a handle and a brush head, the handle and / or the brush head being a hollow chamber have for receiving a cleaning agent, and the brush head having at least one with the hollow chamber communicating opening to the detergent deliver through this opening.

Ein Handreinigungsgerät bzw. eine Klobürste der zuvor beschriebenen Ausgestaltung wird im Rahmen des Gebrauchsmusters DE 86 03 096 U1 beschrieben. Am Ende des Stiels ist eine luftdichte Verschraubung angebracht, die es ermöglicht, jederzeit Reinigungs- und/oder Desinfektionsmittel in den Stiel nachzufüllen. Durch eine am Bürstenkopf durchgehende Haarbohrung tritt das Reinigungsmittel sparsam dosiert aus, sobald die Bürste mit Wasser in Berührung kommt. Bei Benutzungsende ist der Zufluss des Reinigungs- oder des Desinfektionsmittels gestoppt, da der Hohlkörper im Stiel am oberen Ende luftundurchlässig verschlossen ist.A hand cleaning device or a toilet brush of the previously described Design is within the scope of the utility model DE 86 03 096 U1 described. At the end of the stem is an airtight screw fitting attached, which enables cleaning agents and / or disinfectants at any time refill in the stem. Through a continuous on the brush head The detergent is dosed sparingly into the hair hole as soon as the brush comes into contact with water. At the end of use is the inflow of cleaning or Disinfectant stopped because the hollow body in the stem is sealed airtight at the upper end.

Ob sich mit einem solchen Handreinigungsgerät zufriedenstellende Reinigungswirkungen erzielen lassen, sei dahingestellt. Jedenfalls ist die Handhabung schon deshalb aufwendig, weil zum Nachfüllen jeweils die Schraubkappe entfernt und der Stiel mit dem Reinigungsmittel aufgefüllt werden muss.Whether satisfactory with such a hand cleaning device Let cleaning effects be achieved. In any case, the handling is therefore complex, because the screw cap is removed for refilling and fill the stem with the detergent got to.

Ähnlich bedienungsunfreundliche Handreinigungsgeräte bzw. Klobürsten werden im Rahmen der DE 200 20 681 U1 oder auch der DE 200 13 266 U1 beschrieben. Im erstgenannten Fall findet sich ein Reinigungsmittel innerhalb des Stiels. Um die Klobürste zu benutzen, wird eine Pumpe betätigt. Ähnlich geht die DE 200 13 266 U1 vor, bei welcher ein externer Nachfülltank zur Aufnahme des Reinigungsmittels vorgesehen ist.Similar user-unfriendly hand cleaning devices or Toilet brushes are in the context of DE 200 20 681 U1 or described in DE 200 13 266 U1. In the former case there is a detergent inside the stem. Around To use the toilet brush, a pump is operated. Similar DE 200 13 266 U1, in which an external Refill tank provided to hold the detergent is.

Ähnlich geht die DE 295 17 960 U1 vor, welche am oberen Ende des zur Aufnahme einer Reinigungsflüssigkeit bestimmten hohlen Stiels über eine Pumpe verfügt. Nahe dem unteren Ende des Stiels sind aus dessen inneren nach außen führende Sprühdüsen angeordnet, durch welche bei Druckbetätigung der Pumpe Reinigungsflüssigkeit auf die zu reinigende Fläche - und nicht den Bürstenkopf - gesprüht wird. Abgesehen davon, dass der Detailaufbau der Pumpe kompliziert ist, lässt sich die Reinigungsflüssigkeit nur dergestalt in den Stiel einbringen, dass eine oberseitige Überwurfmutter inklusive Pumpe entfernt wird. Das ist aufwendig und mühsam.DE 295 17 960 U1 proceeds similarly, which is at the top End of the intended for the absorption of a cleaning liquid hollow stem has a pump. Near the bottom End of the stem are leading from the inside to the outside Spray nozzles arranged, through which the pressure when the Pump cleaning liquid onto the surface to be cleaned - and not the brush head - is sprayed. Apart from this, the detailed structure of the pump is complicated only introduce the cleaning liquid into the stem in such a way that included a top nut Pump is removed. This is complex and tedious.

Ähnlich wird bei der Toilettenbürste entsprechend der DE 42 18 848 A1 vorgegangen. Auch in diesem Fall muss das Reinigungsmittel umständlich in einen hohlen Stiel eingebracht werden.The same applies to the toilet brush according to DE 42 18 848 A1. In this case too, the cleaning agent laboriously introduced into a hollow stem become.

Die WO 02/26081 A1 sieht hier zwar eine Verbesserung in der Weise vor, dass mit einem auswechselbaren Dosierbehälter innerhalb des Stiels gearbeitet wird. Dessen Handhabung und Bevorratung überzeugt jedoch nicht.WO 02/26081 A1 sees an improvement in the Way before that with an interchangeable dosing container working within the stem. Its handling and However, stocks are not convincing.

Der Erfindung liegt das technische Problem zugrunde, ein Handreinigungsgerät bzw. eine Klobürste der eingangs beschriebenen Gestaltung so weiter zu entwickeln, dass die Aufnahme des Reinigungsmittels einfach gelingt und die Handhabung gegenüber dem bisher Bekannten verbessert ist.The invention is based on the technical problem Hand cleaning device or a toilet brush of the type described above To develop design so that the The detergent is easy to absorb Handling compared to the previously known is improved.

Zur Lösung dieser technischen Problemstellung ist ein gattungsgemäßes Handreinigungsgerät bzw. eine Klobürste erfindungsgemäß dadurch gekennzeichnet, dass die Hohlkammer als Aufnahmekammer für einen Saugkolben ausgebildet ist, welcher während seines Saughubes durch die Öffnung das Reinigungsmittel in die Hohlkammer saugt und beim Druckhub das Reinigungsmittel über eine oder mehrere Auslassöffnungen abgibt.To solve this technical problem is a generic one Hand cleaning device or a toilet brush according to the invention characterized in that the hollow chamber as Receiving chamber is designed for a suction piston, which during the suction stroke through the opening Detergent sucks into the hollow chamber and during the pressure stroke the cleaning agent through one or more outlet openings emits.

Die Auslassöffnung und die Öffnung zur Aufnahme des Reinigungsmittels mögen ineinander fallen, so dass die Aufnahme des Reinigungsmittels und dessen Abgabe über ein und dieselbe Öffnung erfolgen. Üblicherweise sind die Auslassöffnung bzw. die mehreren Auslassöffnungen und die Öffnung zur Aufnahme des Reinigungsmittels jedoch als unterschiedliche Öffnungen ausgebildet.The outlet opening and the opening for receiving the cleaning agent like to fall together, so the inclusion of the cleaning agent and its delivery via one and the same Opening. Usually the outlet opening or the plurality of outlet openings and the opening for However, absorption of the cleaning agent as different Openings formed.

Dabei hat es sich als vorteilhaft erwiesen, die Auslassöffnungen im Kopfbereich des Bürstenkopfes anzuordnen, um den Austritt des Reinigungsmittels an dieser Stelle zu gewährleisten. Auf diese Weise verteilt sich das Reinigungsmittel beginnend vom Kopfbereich des Bürstenkopfes über den gesamten Bürstenkopf bis hin zu seinem Tiefsten. Das ermöglicht eine besonders intensive und gleichmäßige Reinigungswirkung, weil das Reinigungsmittel praktisch automatisch über den Bürstenkopf verteilt wird. The outlet openings have proven to be advantageous to arrange in the head area of the brush head to the Ensure that the detergent escapes at this point. In this way, the detergent is distributed starting from the head area of the brush head over the entire Brush head down to its lowest point. This allows a particularly intensive and even cleaning effect, because the detergent is practically automatic the brush head is distributed.

Auch lässt sich hierdurch erreichen, dass unter Umständen schwer zugängliche Bereiche mit dem durch die Auslassöffnungen austretenden Reinigungsmittel befeuchtet werden. Hierfür sorgt die erfindungsgemäße Ausbildung des Stieles in Gestalt einer Art Spritze. Denn je nach der Geschwindigkeit, mit welcher während des Druckhubes der Saugkolben in die Aufnahmekammer eingedrückt wird, lässt sich auch die Austrittsgeschwindigkeit des Reinigungsmittels aus den Auslassöffnungen steuern. Ist diese Geschwindigkeit gering, so sickert das Reinigungsmittel aus den Auslassöffnungen auf die einzelnen Borsten des Bürstenkopfes und sorgt hier für eine gleichmäßige Benetzung. Bei erhöhter Austrittsgeschwindigkeit kann darüber hinaus das Reinigungsmittel gleichsam auf die zu reinigenden Flächen gesprüht werden. Selbstverständlich ist während des Druckhubes auch ein Wechsel der Geschwindigkeiten möglich. Das alles kann ein Benutzer steuern.It can also be done that under certain circumstances areas difficult to access with the through the outlet openings emerging detergents are moistened. The inventive design of the handle ensures this in the form of a kind of syringe. Because depending on the speed, with which the suction piston in during the pressure stroke the receiving chamber is pressed in, the Velocity of the cleaning agent out of the outlet openings Taxes. If this speed is low, so The cleaning agent seeps out of the outlet openings the individual bristles of the brush head and ensures here even wetting. With increased exit speed can also use the detergent as it were sprayed on the surfaces to be cleaned. Of course there is also a during the pressure stroke Changing speeds possible. All of this can Control users.

Dabei hängt der beschriebene Effekt fraglos auch von der Viskosität des Reinigungsmittels und/oder der Größe der Auslassöffnungen ab. Üblicherweise wird man davon ausgehen, dass das Reinigungsmittel in etwa die Eigenschaften von Wasser besitzt, weil das Reinigungsmittel nicht notwendigerweise in konzentrierter Form von dem Stiel des Handreinigungsgerätes aufgenommen wird. Vielmehr kommt an dieser Stelle zumeist eine Mischung aus Reinigungsmittel und Wasser zum Einsatz. Selbstverständlich kann auch nur mit (heißem) Wasser gereinigt werden.The effect described also depends on the Viscosity of the detergent and / or the size of the Exhaust openings. Usually one will assume that the detergent is roughly the properties of Owns water because the detergent is not necessarily in concentrated form from the handle of the hand cleaning device is recorded. Rather arrives mostly a mixture of cleaning agents at this point and water to use. Of course, only be cleaned with (hot) water.

Um die Verteilung des Reinigungsmittels auf die einzelnen Borsten des Bürstenkopfes zu vergleichmäßigen und/oder einen umfassenden Austritt im Sinne eines Sprühens zu gewährleisten, sind die mehreren Auslassöffnungen in der Regel gleichmäßig verteilt über den Umfang des Bürstenkopfes angeordnet. Dabei hat es sich ferner als günstig erwiesen, die Auslassöffnungen in mehreren Reihen anzuordnen, wobei zwischen den in den Reihen angeordneten Auslassöffnungen ein gleichmäßiger Versatz realisiert ist.To distribute the detergent to each Bristles of the brush head to even out and / or to ensure a comprehensive discharge in terms of spraying, are the multiple outlet openings in the Usually evenly distributed over the circumference of the brush head arranged. It has also proven to be beneficial arrange the outlet openings in several rows, being between the outlet openings arranged in the rows a uniform offset is realized.

Demgegenüber ist die Öffnung zur Aufnahme des Reinigungsmittels in der Regel am Tiefsten des Bürstenkopfes vorgesehen. Dadurch kann das Reinigungsmittel vorteilhaft aus einem mit dem Reinigungsmittel gefüllten Behälter angesaugt werden. Bei diesem Behälter mag es sich um einen üblichen Aufnahmebehälter für ein Handreinigungsgerät bzw. eine Klobürste handeln, in welchem das betreffende Gerät in stehender Ausrichtung bevorratet wird. Dieser Behälter bzw. Aufnahmebehälter übernimmt also im Rahmen der Erfindung eine zweifache Funktion. Er dient nicht nur dazu, das Handreinigungsgerät bzw. die Klobürste zu halten, sondern sorgt auch für die Aufnahme des Reinigungsmittels sowie ggf. dessen Vorbereitung (Mischen, unter Umständen Erwärmen etc.). Ausgehend von dem Aufnahmebehälter wird das Reinigungsmittel durch die am Tiefsten des Bürstenkopfes angeordnete Öffnung in die Hohlkammer im Stiel des Handreinigungsgerätes eingesaugt.In contrast, the opening for receiving the cleaning agent usually provided at the lowest point of the brush head. As a result, the cleaning agent can advantageously sucked into a container filled with the detergent become. This container may be a common one Container for a hand cleaning device or a toilet brush act in which the device in question Alignment is stocked. This container or receptacle therefore takes on a within the scope of the invention dual function. It not only serves the hand cleaning device or to hold the toilet brush, but also provides for the absorption of the cleaning agent and, if necessary, its Preparation (mixing, possibly heating etc.). outgoing from the receptacle is the detergent through the lowest opening of the brush head sucked into the hollow chamber in the handle of the hand cleaning device.

In diesem Zusammenhang mag die Öffnung zur Aufnahme des Reinigungsmittels zusätzlich über ein Ventil verfügen. Das Ventil stellt sicher, dass das Reinigungsmittel während des Saughubes des Saugkolbens in die Hohlkammer im Stiel des Handreinigungsgerätes eintreten kann und während des Druckhubes des Saugkolbens nicht aus dieser Öffnung entweicht. Im einfachsten Fall mag es sich bei dem Ventil um eine flexible Lippe handeln, wie mit Bezug zu der Figurenbeschreibung noch näher erläutert wird.In this context, the opening for receiving the Detergent also have a valve. The Valve ensures that the detergent is used during the Suction stroke of the suction piston into the hollow chamber in the stem of the Hand cleaning device can occur and during the pressure stroke of the suction piston does not escape from this opening. In the simplest case, the valve may be one flexible lip act as with reference to the figure description is explained in more detail.

Um die Handhabung des Saugkolbens und den damit zu realisierenden Saughub und Druckhub zu vereinfachen, verfügt der Stiel in der Regel über seitliche Haltevorsprünge. Diese Haltevorsprünge werden zumeist so genutzt, dass der Stiel zwischen Zeigefinger und Mittelfinger eingeklemmt wird, wobei sich die beiden vorgenannten Finger an den beiden seitlichen Haltevorsprüngen abstützen. Demgegenüber dient der Daumen dazu, beim Druckhub den Saugkolben mehr und mehr in die Aufnahmekammer einzudrücken.In order to handle the suction piston and the implementable with it The has to simplify suction and pressure stroke As a rule, the handle has lateral retaining projections. This Retaining tabs are mostly used so that the stem is pinched between the index finger and middle finger, the two aforementioned fingers on the two Support lateral retaining projections. In contrast serves the thumb, the suction piston more and more during the pressure stroke press into the receiving chamber.

Auch beim Ansaugen des Reinigungsmittels können die Haltevorsprünge vorteilhaft genutzt werden. Hier wird man zumeist mit deren Hilfe mit der einen Hand den Stiel festhalten, während die andere Hand den Saugkolben während des Saughubes aus der Aufnahmekammer herauszieht. Insgesamt hat es sich in diesem Zusammenhang als günstig erwiesen, wenn die Haltevorsprünge über eine konvexe Oberfläche mit in Richtung zum Bürstenkopf ausgebildeter Krümmung verfügen, weil dann eine besonders ergonomisch günstige Gestaltung vorliegt.The holding projections can also be used when sucking in the cleaning agent be used to advantage. Here you mostly get hold the handle with one hand, while the other hand holds the suction piston during the Pulls suction strokes out of the receiving chamber. Overall in this context it turned out to be favorable if the holding projections over a convex surface with in Have a curvature towards the brush head, because then a particularly ergonomically favorable design is present.

Schließlich empfiehlt die Erfindung, den Stiel aus Kunststoff, Metall, Holz oder einer Kombination der vorgenannten Materialien auszubilden. Dadurch lässt sich das Handreinigungsgerät optisch besonders ansprechend gestalten. Die gleichen Materialien können prinzipiell auch für den Saugkolben zum Einsatz kommen. Denkbar ist es hier unter anderem, den Stiel aus einem durchsichtigen Kunststoff zu produzieren, während der Saugkolben ebenfalls aus Kunststoff besteht. Dadurch kann das Einsaugen des Reinigungsmittels in das Handreinigungsgerät bzw. die Klobürste besonders vorteilhaft beobachtet werden. Auch liegt es natürlich im Rahmen der Erfindung, nur einen Schlitz des Stieles durchsichtig zu gestalten, um den betreffenden Saugvorgang (und natürlich auch das Austreten des Reinigungsmittels) zu beobachten.Finally, the invention recommends the plastic handle, Metal, wood or a combination of the above Train materials. This allows the hand cleaning device make it visually appealing. The In principle, the same materials can also be used for the suction piston are used. It is conceivable here, among other things, the stem from a clear plastic produce while the suction piston is also made of plastic consists. This can suck up the detergent especially in the hand cleaning device or the toilet brush be observed advantageously. It is also natural, of course in the context of the invention, only a slit of the stem transparent to make the suction process in question (and of course the detergent will leak) too observe.

Es versteht sich, dass der Saugkolben gegebenenfalls mit einer fußseitigen Dichtungsausbildung ausgerüstet ist, um zu verhindern, dass das Reinigungsmittel seitlich am Saugkolben vorbeitreten kann. Diese Gefahr besteht natürlich insbesondere beim Druckhub. Schließlich wird man in der Regel auch dafür sorgen, dass der Saugkolben nicht vollständig aus der Aufnahmekammer bzw. Hohlkammer herausgezogen werden kann. Das lässt sich beispielsweise mit Hilfe von Anschlägen erreichen.It is understood that the suction piston may also be used a base seal formation is equipped to to prevent the detergent on the side of the suction piston can step forward. Of course there is a danger especially with the pressure stroke. Eventually you will be in the Usually also ensure that the suction piston is not complete pulled out of the receiving chamber or hollow chamber can be. This can be done, for example, with the help of attacks.

Im Ergebnis wird ein Handreinigungsgerät bzw. eine Klobürste zur Verfügung gestellt, die durch eine frappierend einfache Aufnahme des Reinigungsmittels überzeugt. Denn dieses wird im Zuge eines Saughubes von dem Saugkolben in den hohlen Stiel eingesaugt und während eines Druckhubes des Saugkolbens über die Auslassöffnungen abgegeben. Die Vorbereitung des Reinigungsmittels erfolgt hiervon getrennt, nämlich in dem Behälter bzw. Aufnahmebehälter für das Handreinigungsgerät. Ein umständliches Auf- und/oder Nachfüllen der Hohlkammer im Innern des Stieles ist also nicht erforderlich. Auch ist die Bedienung äußerst einfach, wozu insbesondere die Haltevorsprünge beitragen, die gleichsam ein Widerlager für einzelne Finger oder eine Hand des Benutzers zur Verfügung stellen. Hierin sind die wesentlichen Vorteile zu sehen.The result is a hand cleaning device or a toilet brush provided by a striking easy absorption of the cleaning agent is convincing. Because this is in the course of a suction stroke from the suction piston in sucked the hollow stem and during a pressure stroke of the suction piston through the outlet openings. The Preparation of the detergent is done separately, namely in the container or receptacle for the hand cleaning device. A cumbersome opening and / or Refilling the hollow chamber inside the stem is so not mandatory. Operation is also extremely simple, to which in particular the holding projections contribute as it were an abutment for individual fingers or a hand of the user. Here are the main ones See benefits.

Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellenden Zeichnung näher erläutert; es zeigen:

In den Figuren ist ein Handreinigungsgerät dargestellt, bei dem es sich im Ausführungsbeispiel um eine Klobürste handelt. Selbstverständlich mag man das dargestellte Handreinigungsgerät prinzipiell auch nicht nur zur Reinigung von Toiletten einsetzen, sondern es sind jedwede Verwendungszwecke denkbar, bei denen per Hand ein Reinigungsmittel auf eine Bürste und/oder eine zu reinigende Fläche aufzubringen ist und die Bürste in Verbindung mit dem Reinigungsmittel für die reinigende Wirkung sorgt. A hand cleaning device is shown in the figures, at which is a toilet brush in the exemplary embodiment. Of course you like the hand cleaning device shown in principle not only for cleaning of toilets, but there are any uses conceivable, where a cleaning agent by hand to be applied to a brush and / or a surface to be cleaned and the brush in connection with the detergent ensures the cleaning effect.

Das dargestellte Handreinigungsgerät verfügt in seinem grundsätzlichen Aufbau über einen Stiel 1 sowie einen Bürstenkopf 2 mit Borsten 3. Die Borsten 3 sind über die gesamte freiliegende Oberfläche des nahezu kugelförmigen Bürstenkopfes 2 mehr oder minder gleichmäßig verteilt. Darüber hinaus verfügt der Bürstenkopf 2 über mehrere Öffnungen 4, 5, und zwar eine Öffnung 4 zur Aufnahme eines Reinigungsmittels und eine Vielzahl von Auslassöffnungen 5 zur Abgabe des Reinigungsmittels.The hand cleaning device shown has in his basic structure via a stem 1 and a Brush head 2 with bristles 3. The bristles 3 are over the entire exposed surface of the nearly spherical Brush head 2 more or less evenly distributed. In addition, the brush head 2 has several openings 4, 5, namely an opening 4 for receiving a Detergent and a variety of outlet openings 5 for dispensing the cleaning agent.

Die Auslassöffnungen 5 finden sich ausweislich der Fig. 3b im Rahmen des Ausführungsbeispiels im Kopfbereich des Bürstenkopfes 2. Man erkennt, dass die Auslassöffnungen 5 gleichmäßig über den Umfang des Bürstenkopfes 2 verteilt angeordnet sind und mehrere Reihen formen. Im Rahmen der Darstellung sind zwei Reihen an Auslassöffnungen 5 realisiert, wobei die jeweiligen Auslassöffnungen 5 versetzt zueinander und gleichmäßig verteilt angeordnet sind. Das ist jedoch nicht zwingend. Jedenfalls finden sich die Auslassöffnungen 5 jeweils zwischen den Borsten 3, die zu Borstenbüscheln zusammengefasst sind.The outlet openings 5 can be found in FIG. 3b in the context of the embodiment in the head area of the Brush head 2. It can be seen that the outlet openings 5 evenly distributed over the circumference of the brush head 2 are arranged and form several rows. As part of the Illustration shows two rows of outlet openings 5, the respective outlet openings 5 offset from one another and are evenly distributed. This is however not mandatory. In any case, there are the outlet openings 5 each between the bristles 3, which form tufts of bristles are summarized.

Demgegenüber ist die Öffnung 4 zur Aufnahme des Reinigungsmittels am Tiefsten des Bürstenkopfes 2 vorgesehen. Durch diese Öffnung 4 gelangt das Reinigungsmittel in den hohl ausgebildeten Stiel 1. Tatsächlich verfügt der Stiel 1 über eine Hohlkammer 6 in seinem Innern, die mit den betreffenden Öffnungen 4, 5 kommuniziert, d. h. verbunden ist. Grundsätzlich mag auch der Bürstenkopf 2 ergänzend oder alternativ über die Hohlkammer 6 verfügen. Auch mehrere Hohlkammern 6 sind denkbar. Der Öffnung 4 ist ein lediglich angedeutetes Ventil 7 im Innern des Bürstenkopfes 2 zugeordnet, welches als Gummilappen ausgebildet ist.In contrast, the opening 4 for receiving the cleaning agent provided at the lowest of the brush head 2. By this opening 4 passes the cleaning agent into the hollow trained stem 1. Actually, stem 1 has a hollow chamber 6 in its interior, which with the concerned Openings 4, 5 communicated, i. H. connected is. In principle, the brush head 2 may also be supplementary or alternatively have the hollow chamber 6. Several too Hollow chambers 6 are conceivable. The opening 4 is only one indicated valve 7 assigned inside the brush head 2, which is designed as a rubber rag.

Die Hohlkammer 6 ist als Aufnahmekammer 6 für einen Saugkolben 8 ausgeführt, welcher sich in der Hohlkammer 6 auf und nieder bewegen kann. Damit der Saugkolben 8 unverlierbar in der Hohlkammer 6 gehalten wird, verfügt die Hohlkammer 6 über kopfseitige Anschläge 9. Eine fußseitige Dichtungsausbildung 10 an dem aus Kunststoff bestehenden Saugkolben 8 sorgt dafür, dass das Reinigungsmittel nicht seitlich am Saugkolben 8 vorbei aus dem Stiel 1 austreten kann.The hollow chamber 6 is a receiving chamber 6 for a suction piston 8 executed, which is in the hollow chamber 6 and can move down. So that the suction piston 8 cannot be lost is held in the hollow chamber 6, the hollow chamber 6 via stops on the head side 9. A seal on the foot side 10 on the plastic suction piston 8 ensures that the detergent is not on the side can exit the stem 1 past the suction piston 8.

Im Rahmen eines Saughubes entsprechend der Fig. 1 nimmt der Stiel 1 bzw. die Aufnahmekammer 6 durch eine Aufwärtsbewegung des Saugkolbens 8 Reinigungsmittel durch die Öffnung 4 auf. Bei diesem Vorgang taucht der Bürstenkopf 2 in einen mit dem Reinigungsmittel gefüllten Behälter 11 ein, der im Detail in Fig. 3a dargestellt ist. Der Behälter 11 besitzt eine an die Kugelform des Bürstenkopfes 2 angepasste halbkugelförmige Wanne 12, die mit dem Reinigungsmittel gefüllt ist. Dadurch kann bei einer Saugbewegung des Saugkolbens 6 das Reinigungsmittel über die Öffnung 4 bei geöffnetem Ventil 7 in den Stiel 1 bzw. die Aufnahmekammer 6 eintreten.
Bei einem Druckhub und geschlossenem Ventil 7 tritt das Reinigungsmittel dagegen über die Auslassöffnungen 5 nach außen aus, wie dies in der Fig. 2 gezeigt ist. Das hat zur Folge, dass sich das Reinigungsmittel auf den Borsten 3 des Bürstenkopfes 2 verteilt und/oder gegen eine zu reinigende Fläche gesprüht wird. Das hängt von der Geschwindigkeit ab, mit welcher der Saugkolben 8 in der Aufnahmekammer 6 beim Druckhub bewegt wird. In the course of a suction stroke according to FIG. 1, the handle 1 or the receiving chamber 6 receives cleaning agent through the opening 4 by an upward movement of the suction piston 8. In this process, the brush head 2 is immersed in a container 11 filled with the cleaning agent, which is shown in detail in FIG. 3a. The container 11 has a hemispherical trough 12 which is adapted to the spherical shape of the brush head 2 and is filled with the cleaning agent. As a result, during a suction movement of the suction piston 6, the cleaning agent can enter the stem 1 or the receiving chamber 6 via the opening 4 when the valve 7 is open.
With a pressure stroke and closed valve 7, on the other hand, the cleaning agent exits to the outside via the outlet openings 5, as is shown in FIG. 2. The result of this is that the cleaning agent is distributed on the bristles 3 of the brush head 2 and / or is sprayed against a surface to be cleaned. This depends on the speed at which the suction piston 8 is moved in the receiving chamber 6 during the pressure stroke.

Der Stiel 1 verfügt in seinem Kopfbereich über seitliche Haltevorsprünge 13, die jeweils spiegelsymmetrisch zu einer Symmetrieachse S angeordnet sind, auf welcher auch die Öffnung 4 befindlich ist, über welche das Reinigungsmittel in die Aufnahmekammer 6 angesaugt wird. Die beiden Haltevorsprünge 13 verfügen über eine konvexe Oberfläche und eine Krümmung in Richtung zum Bürstenkopf 2. Dadurch sind die beiden Haltevorsprünge 13 in der Lage ein Widerlager für einzelne Finger oder die gesamte Hand eines Bedieners beim Saughub und auch beim Druckhub zur Verfügung zu stellen. Das ist einleitend bereits beschrieben worden.The stem 1 has lateral in its head area Holding projections 13, each mirror-symmetrical to one Axis of symmetry S are arranged, on which also the opening 4 is located, via which the cleaning agent in the receiving chamber 6 is sucked. The two retaining tabs 13 have a convex surface and a Curvature in the direction of the brush head 2 two retaining projections 13 capable of an abutment individual fingers or the entire hand of an operator when Suction stroke and also to provide the pressure stroke. This has already been described in the introduction.

Der Stiel 1 mag aus durchsichtigem Kunststoff gefertigt sein. Es sind aber auch Ausgestaltungen aus Metall oder Holz denkbar sowie Kombinationen der vorgenannten Werkstoffe. Dagegen wird man den Saugkolben 8 überwiegend aus Kunststoff im Zuge eines Spritzgießvorganges herstellen. In diesem Zusammenhang kann dann auch die Dichtungsausbildung 10 in einem Zug mit realisiert werden. Das gilt ebenso für einen oberseitigen Knauf 14, der dafür sorgt, dass der Saugkolben 8 nur soweit in die Aufnahmekammer 6 eintaucht, wie dies in der Fig. 2 dargestellt ist. Der Knauf 14 begrenzt also den Weg des Saugkolbens 8 beim Druckhub. Demgegenüber stellen die Anschläge 9 sicher, dass der Weg des Saugkolbens 8 beim Saughub begrenzt wird. Der Saugkolben 8 wird folglich unverlierbar in der Aufnahmekammer 6 des Stieles 1 gehalten.The handle 1 may be made of transparent plastic his. But there are also designs made of metal or Wood conceivable as well as combinations of the aforementioned materials. In contrast, the suction piston 8 will predominantly be made Manufacture plastic in the course of an injection molding process. In The seal formation can then also be used in this connection 10 can be realized in one go. This also applies to a top knob 14, which ensures that the Suction piston 8 only so far immersed in the receiving chamber 6, as shown in FIG. 2. Knob 14 limits thus the path of the suction piston 8 during the pressure stroke. In contrast, the stops 9 ensure that the path of the Suction piston 8 is limited during the suction stroke. The suction piston 8 is consequently captive in the receiving chamber 6 of the Stem 1 held.
