Toilet brush set

Abstract

A toilet brush set characterized in that a hollow toilet brush (37) with an integrated mechanical catapult device, which, by being pulled upwards by hand against its spring force, brings mechanical energy into a resting state, which is then, by an abrupt release, strongly accelerated onto a metered quantity of a filled liquid agent, so that this is flung through at least one opening in the brush core (13), with a holder which, by means of a two-shell, rotatable joint formation, together with the magnetism integrated therein, enables a force-fit, but easily releasable by hand, connection between the upper holder shell (15) and the lower holder shell (18).

Description

Technical field to which the invention relates

[0001] The invention relates to toilet brush sets whose toilet brush has a better cleaning function, enhanced by the addition of liquid agents, and thereby offers further advantages in terms of handling, hygiene, well-being, sustainability and environmental protection, as well as their holders, which are easier to use, empty and clean due to their design and mechanisms. Relevant state of the art

[0002] Toilet brush sets of the commonly used design consist solely of a monolithic brush handle, a brush core to which the bristles or their commercially available alternatives are attached, and a corresponding, adapted, monolithic brush holder. Toilet brushes that can be filled with liquid cleaning agents are patented and registered as utility models, but due to their limited functionality and ease of use, they are rarely found on the market.

[0003] Contrary to the submitted invention, which catapults the liquid agent onto the bristles in a metered form, these inventions attempt to transport the liquid agent, at least as droplets, in front of the brush core. In doing so, they have not adequately considered certain physical properties, such as negative pressure in containers, the required pressure of pumps, lever arm effects, the viscosity and inertia of the liquid agent, plastic deformation and reforming, communicating vessels, and other factors.

[0004] These inventions are not based on a powerful catapult effect but on: cartridge filling, pump spray system, metering pump, pump system, nozzle system, pump device with side operation, metering button with suction opening, hose section and external closure, balloon pump handle, pressure valve and inserted pressurized gas cartridge, suction via hose, screwed-on container with nozzle, control of the outlet opening via the respective position of the elastically deformable connecting joint and other things.

[0005] The cleaning function of commonly used toilet brushes is ineffective, limited to simply shifting excrement around under the influence of the toilet flush. Several flushes are required to clean the toilet bowl and subsequently the brush itself, even to achieve a visually acceptable result. These toilet brushes have no further impact on hygiene, well-being, sustainability, or environmental protection. Using such brushes necessitates regular, intensive cleaning with manual scrapers or copious amounts of chemicals, which are then discharged into the local wastewater system for treatment. This intensive cleaning is necessary to remove stubborn limescale, urine scale, odor-causing deposits, and pathogens.

[0006] Odors during toilet use are usually altered, for personal comfort, by means of strong chemicals in the form of room sprays or scent pendants attached to the toilet rim, the substances of which also enter the wastewater with every flush, even after only urination.

[0007] The corresponding holders, either floor-standing or wall-mounted, for storing and retrieving the toilet brush, as well as collecting and emptying its dripping water, typically consist of a single, monolithic component that is cumbersome to use, empty, and clean. The other two-part holders commonly available on the market, also floor-standing or wall-mounted, are likewise cumbersome and unhygienic to handle.

[0008] Contrary to the submitted invention, which, by means of its articulated lower and upper mounting shells, its integrated magnetism, and its design closely adapted to the brush circumference, enables better hygienic handling and easier cleaning or emptying for optimized and vertical storage of the toilet brush within the upper mounting shell, the holders available on the market have an outer shell and a loose, inserted, tubular inner shell, which, due to their depth, are only difficult and unhygienic to remove and clean.Since these inner containers, for easier removal, have a low weight and their inner diameter must be significantly larger than the outer diameter of the toilet brush (to prevent the brush from unintentionally pulling the inner container along with it every time it is removed), the toilet brush can only be stored loosely and at an angle. This visual flaw, if addressed, is concealed by a holder end cap anchored in the middle of the toilet brush handle. This cap can scratch the toilet bowl during cleaning and prevents the necessary diffusion of any dripping liquid when the toilet brush is stored.

[0009] In view of the millions of times they are used daily, it is important to produce easy-to-use holders and toilet brushes with better cleaning performance and operation, so that fresh water consumption, wastewater reprocessing and the use of strong chemicals are minimized, while at the same time taking into account the concerns of hygiene, well-being, ease of use, sustainability and environmental protection. Technical problem to be solved

[0010] The present invention aims to provide toilet brush sets, consisting of a toilet brush and holder, with improved handling, enhanced cleaning function, as few additional but recyclable components as possible, and a replaceable brush button, which reduce water and wastewater consumption, prevent the formation of deposits and pathogens, alter odor formation, sustainably reduce wear and tear on the toilet brushes, and simplify their storage, handling, emptying, and cleaning.

[0011] For the function of such toilet brushes, a catapult construction is to be invented which uses mechanical energy to hurl a measured, liquid mass from a state of rest at high speed into the target.

[0012] For the function of such brackets, a mechanically firmly connected, but also easily detachable, shell construction is to be invented, which allows storage on the floor or on the wall. Disclosure of the invention

[0013] According to the present invention, a toilet brush with holders, which is to be filled with a liquid medium, is provided, comprising the following: a brush handle with a fillable cavity and an upper and lower opening each; a brush head with a hollow brush core and the bristles commonly used, or their commercially available alternatives, also provided with an upper and lower opening, which is attached to the lower end of the brush handle, along with a seal to prevent liquid leakage between the brush handle and the brush head; an operating rod, in a straight version, or with a specific design or supplemented with a functional, adjustable operating element, which projects beyond the upper end of the brush handle for the purpose of handling the toilet brush and has a seal attached to it at its lower end in a force-fit, adjustable manner, which is located inside the brush core;together with at least one outlet opening at its lower end, forming a closure that can be opened and closed, a return spring that uses the lower end of the brush handle as the first abutment and is fixed outside the lower end of the brush handle, on the operating rod, by the necessary second adjustable abutment, which enables the catapult-like closing of the opening(s) and as an alternative in simplified form, a monolithic operating rod with integrated but non-adjustable spring abutment, integrated but non-adjustable seal, designed locking mechanism against rotation and integrated thread for a closure part, a mounting base designed as a partial hinge, to be placed on the floor and an alternative mounting base designed as a partial hinge, to be hung on the wall, each with a force-fit connection achieved by magnetism as required,A partially hinged upper mounting shell, adapted to the brush head, which serves to hold, store and remove the toilet brush.

[0014] A key advantage of this brush is that the catapult-like closing of the dispensing opening(s) at the inner, lower end of the brush head propels the liquid cleaning agent, which has accumulated in front of the closure when it is briefly opened, through the dispensing opening(s) in a dissolved, coarsely atomized form onto the bristles. This action of the toilet brush only needs to be performed once during use, as its effect is long-lasting. This drastically minimizes the consumption of the cleaning agent and significantly enhances the cleaning performance.

[0015] An advantage with regard to the holder is that the easily and readily available, force-fit connection between the lower and upper parts of the holder ensures trouble-free, permanent removal and reinsertion of the toilet brush and allows for easy removal of the upper part of the holder with the toilet brush for emptying or cleaning purposes, without having to bend down.

[0017] The following section will first refer to the drawings. Fig. 1 - Fig. 25 referenced.

[0018] Accordingly, the toilet brush set comprises a toilet brush according to the preferred embodiment of the present invention, a tubular brush handle (1) for storing the liquid agent, the upper, elliptically shaped end region (24) of which is open and the lower end region of which is also open, but is provided with a sealing ring (2) to prevent the liquid agent from escaping and with an external thread (3), which in turn has an internal opening (4) for the flow of the liquid agent, an operating part (5) with at least one continuous vent opening (22), a screw cap (6), a non-continuous internal thread opening (26) and a continuous filling opening (21), which is loosely inserted into the upper, open, elliptically shaped end region (24) of the brush handle (1), wherein the shaft of the operating part (5) serves as a fitting,also elliptically shaped (23) and thus only allows axial longitudinal displacement, or prevents an unintended rotation of the operating part (5), which in turn would allow the screw cap (6) to open unintentionally, a shaped, curved operating rod (7) which at its upper end, eccentrically, is connected to the provided non-through threaded opening (26) in the operating part (5) by screwing it in, in a force-fit manner, but adjustable with regard to its final longitudinal position, and whose lower part is inserted axially through the opening in the external thread (4) of the brush handle (1), so that it protrudes unfastened (25) beyond the lower end of the brush handle (1) and does not impede the flow of the liquid medium, a shaped spiral spring (8),which uses the lower end of the brush handle as a first abutment or is placed over the protruding part of the operating rod (7) and centers the latter in its longitudinal axis, a washer (9) and a nut (10) as an adjustable second abutment, a shaped seal (11) which is attached to the lower end of the protruding operating rod (7) and is secured against possible rearward slippage by a nut (12), also as an abutment, a hollow brush core (13) with an internal thread (27) for screwing into the brush handle external thread (3) and thereby achieving slight pre-tensioning of the spring (8) or pressing the seal (11) against the outlet opening (14) which serves as a closure, a retaining upper shell (15) shaped hemispherically on the outside as a partial hinge for receiving the toilet brush (37) or the,The brush head consists of a brush core (13) and the bristles (31) anchored thereto and commonly used, or their commercially available alternatives, and is provided with an axially centrally mounted magnet (16) together with a preferably screwable, closure cover (17), a lower mounting shell (18) which is internally hemispherical, designed as a partial hinge and adapted to the upper mounting shell, serving as a floor mount (35) or wall mount (36) with suction cup attachment or screw attachment (38), for receiving the respective identical upper mounting shell (15), also provided with a preferably screwable, closure cover (20) and an axially centrally mounted magnet (19) which attracts the magnet (16) of the upper mounting shell and thus connects the upper mounting shell (15) to the lower mounting shell (18) by friction until the desired mechanical release.

[0019] The toilet brush is assembled by connecting the operating part (5) to the operating rod (1) by screwing it into the opening (26). The operating rod is then inserted from above into the brush handle (1), where it is fitted with a spring (8), a seal (11), and the corresponding mounting hardware (9), (10), (12). Screwing in the brush head (13) synchronously presses the connecting seal (2), the operating rod (7) with the seal (11), and the spring (8) into place, thus stabilizing and sealing the entire mechanism.

[0020] The toilet brush (37) is filled by means of the operating part (5), after removing the screw cap (6), preferably by inserting the nozzle of a soft bottle filled with a slightly viscous substance through the filling opening (21) of the operating part (5), whereby the air located in the cavity of the brush handle (1) and to be displaced can escape through the vent openings (22).

[0021] The toilet brush (37) is operated by manually pulling the closed operating part (5) axially upwards and then immediately releasing it.

[0022] By manually pulling the control element (5) and its force-locking transmission to the operating rod (7) against the force of the coil spring, the coil spring (8) is tensioned (29) and the operating rod (7), with the also force-locking seal (11), is moved away from the lower outlet opening (14) of the brush core, thereby allowing the liquid agent to penetrate into the front area (28) of the brush core (13). The subsequent release of the control element (5) catapults the seal (11) of the mechanical assembly back onto the outlet opening (14), thereby propelling a portion of the intruding liquid agent outwards through the outlet opening (14) in a dissolved, coarsely atomized form into the front bristle area (39), while simultaneously resealing the outlet opening (14) inside the bristle core (13).This process uses mechanical energy to propel a measured amount of liquid mass from a stationary state at high speed into the target. The stable mechanical connection of the individual components allows for easy replacement of the brush head.

[0023] The toilet brush holder (35) is operated, as usual (32), by manually inserting and removing the toilet brush (37) into the upper holder shell (15) by grasping the brush handle (1). The attraction of the two magnets (16) and (19) ensures a positive connection between the upper and lower holder shells, which also provides sufficient resistance to the compressed bristles (31), allowing the toilet brush (37) to stand upright and stably, when it is pulled out. To remove (33) the upper holder shell (15), which is designed as a partial hinge, the toilet brush (37), acting as a lever arm, simply needs to be pushed slightly to the side. This causes the lower holder shell (18) to support the upper holder shell, creating a pivot point (30) that overcomes the attractive force of the two magnets (16) and (19).The manual lifting (34) of the toilet brush (37) held by the brush handle (1), with the upper holder shell (15) carried along or still attached by the crushed bristles (31), for the purpose of emptying, removing and cleaning is then easily possible while standing, without having to bend over. Description of a second way of carrying out the invention

[0024] The following refers to the drawings Fig. Reference is made to pages 26-27.

[0025] Accordingly, the toilet brush set comprises a toilet brush according to the simplified embodiment and, to distinguish it from the preferred embodiment of the present invention, a tubular brush handle (54) for storing the liquid medium, the upper end of which is closed but includes openings for the operating rod (39), the vent (41) (42) and the filling (40), an operating rod (39), only one washer and a longer seal (43).

[0026] The assembly is carried out by inserting the operating rod (39) through the upper opening (42) and then through the opening (41), which prevents it from twisting, in order to then be fitted with a spring (8) and a seal (43) at the bottom. Screwing in the brush head (13) synchronously presses the seal (43) against the positively connected operating rod (39) and the spring (8), thus stabilizing and sealing the entire mechanism.

[0027] After filling this toilet brush through the opening (40), it is operated by manually pulling the operating rod (39) axially upwards and then immediately releasing it. Description of a third way to implement the invention

[0028] The following refers to the drawings Fig. Reference is made to pages 28-30.

[0029] Accordingly, the toilet brush set comprises a toilet brush according to a further embodiment and, to distinguish it from the embodiments of the present invention described above, a continuously straight and axially mounted operating rod (48), an operating part (46) mounted outside the upper end of the brush handle (55) and attached to the operating rod, a spiral spring (47) fixed to the operating rod (48) by means of a nut (49) and washers (50) + (51) and a permanently attached closure (58).

[0030] The assembly is carried out by inserting the operating rod (48) into the brush handle (55) from above after the operating part (46) has been assembled, along with the spring (47) and the fastening parts (49-51), in order to then be fitted at the bottom with a spring and a seal and the associated fastening material.

[0031] This toilet brush is operated by manually pulling the control part (46) axially upwards in two steps. To fill the toilet brush, the weaker spring (47) in the control part (46) is tensioned so that a sufficient distance is created between the brush handle edge and the underside of the control part (52), allowing the nozzle of a soft bottle filled with slightly viscous cleaning fluid to be inserted through the filling opening (57). To dispense the cleaning fluid, the control part (46) is pulled (50) until the stronger spring located in the brush core is also tensioned, and then the control part is released.

[0032] The following refers to the drawings Fig. Reference is made to pages 31-36.

[0033] Accordingly, the toilet brush set comprises a toilet brush according to a further embodiment and, to distinguish it from the embodiments of the present invention described above, an operating element (60) partially inserted within the upper area of ​​the brush handle (59), a continuously straight and axially mounted operating rod (58) to which the operating element (60) is movably attached upwards, a spiral spring (61), a fastening nut (62) and two washers (63) + (64).

[0034] The assembly process is analogous to the third method.

[0035] This toilet brush is operated by manually pulling the control element (60) upwards in two steps. To fill the toilet brush, the weaker spring (61) in the control element (60) is tensioned so that a sufficient distance (65) is created between the edge of the brush handle and the recess in the control element (60). This allows the nozzle of a soft bottle filled with a slightly viscous cleaning agent to be inserted through the filling opening (65). To dispense the cleaning agent, the control element (60) is pulled (66) until the stronger spring (67) located in the brush core is also tensioned and then released.
