The device (1) includes an external clip-on connector element (13) for connection to a chlorinated water (AC) outlet hose (M2) and which is fitted to the end of the overflow pipe (LA) of the cistern (CA), thereby improving installation and providing a better finish for the installed assembly.

Description

[0001] DESCRIPTIVE REPORT

[0002] "Constructive arrangement introduced in an automatic sanitizing device for toilet flush tanks"

[0003] Introduction and objectives of the model:

[0004]

[0001] This descriptive report refers to a utility model patent application for a constructive arrangement applied to a sanitizing device. This device incorporates, externally, a clip-on connector for the overflow pipe of the flush tank, which allows for more efficient channeling of the sanitizing liquid, prevents the return of harmful gases to the flush tank, and improves the overall appearance of the device when installed.

[0005]

[0002] The new arrangement applied to the device, in addition to the overflow connector, brings a more minimalist configuration that facilitates installation and makes use more intuitive, as well as having fewer external elements that could interfere with its placement in the toilet bowl.

[0006] Technical comments

[0007]

[0003] As is known, the internal environment of the toilet bowl must be kept as deodorized and sterile as possible. To this end, various devices have been developed over time for this purpose.

[0008]

[0004] As a direct reference to the state of the art for the new constructive arrangement to be described, a patent document filed by the inventor / holder of this application is presented, in order to expose the original configuration of the device and its application for a better understanding of the improvement in the new arrangement: BR202022014620-4, entitled “CONSTRUCTIVE ARRANGEMENT INTRODUCED IN A SANITIZING DEVICE FOR A FLUSH TANK, ITS ADAPTER FOR INTERNAL FIXING AND ITS ADAPTER FOR EXTERNAL FIXING”, which claims, in summary, an improvement applied to a sanitizing device, with the main improvements being the device body featuring three clip-on fittings for fixing to a second adapter and a central recess for support for fixing to a first adapter. The second housing of the device has a short internal wall and the first housing is closed at the top by a removable cover.Flow control plates are designed to improve flow control and ensure longer contact time between water and tablets. In an optional design configuration, the device body features only the first housing for chlorine tablets, omitting the second housing, and with a reduced width accompanied by a flute that features only the first outlet channel.

[0009]

[0005] Thus, despite the excellent application of the sanitizing device described in the document above, the inventor saw a need in the market for improvements to bring technical advantages and further reduce the disadvantages of his product.

[0010]

[0006] One of the disadvantages seen so far in the device and its previous configurations is the general arrangement of its installation components, such as the liquid dispensing tube, which are exposed outside the body and can cause confusion during installation and / or hinder the installation and maintenance of the device, also presenting risks of damage when handled incorrectly by the user.

[0011]

[0007] Also, the lids of the devices presented so far do not provide an effective seal for the device, which could cause leaks and / or release particles and gases outside the flush tank, resulting in a strong smell of the chemical product in tablet form housed in the device.

[0012]

[0008] Another feature open to improvement is the connection of the chlorine outlet of the device to the overflow pipe of the flush tank, which is currently done with a simple hose, connected to said outlet and housed inside the overflow pipe without any support. This simple and direct connection may eventually allow the hose to come loose, especially when using shorter hoses, and also allows the release of gases from the chlorine into the flush tank. In addition, this direct connection with a simple hose is not visually appealing to the consumer, who could perceive the overall product as having low construction value.

[0013] Objectives of the model

[0014]

[0009] Thus, in order to solve or mitigate the problems of the state of the art, the inventor presents a new constructive arrangement applied to his device, more minimalist, beautiful and intuitive, incorporating old external elements, previously exposed, and the addition of a clip-on connector for the overflow pipe, conferring greater visual appeal and improving installation and overall use. The device's lid was also designed to allow better sealing of the device's cartridge compartments, preventing gas escape and increasing the symbolic value of the product. In addition, the clip-on connector has a housing for a protective foam to prevent gas escape from the overflow pipe and chlorine splashes into the flush tank, improving its efficiency and preventing damage to the toilet bowl.

[0034] Detailed description of the model

[0035]

[0011] In accordance with the attached figures, the “CONSTRUCTIVE ARRANGEMENT INTRODUCED IN AUTOMATIC SANITIZING DEVICE FOR TOILET FLUSH TANK”, the subject of this patent application, consists, as shown in figures 1 to 7, of a device (1) designed to be installed in flush tanks and to retain the replacement water coming from the float (BO), in order to either mix it with disinfectant product (PD), releasing it directly into the water of the flush tank (CA), or mix it with chlorine tablets (PC), individually, releasing it directly into the toilet bowl (VA). This action is performed to promote complete sanitization of the toilet bowl (VA) during and after flushes for an extended period and in an efficient manner.

[0036]

[0012] As a novelty of this new arrangement, the device ( 1 ) presents a more minimalist configuration, free of external components that hinder its handling and installation, making its application easier and more intuitive, in addition to bringing greater resistance and useful life to the product.

[0037] Preferred configuration:

[0038]

[0013] The device (1) is designed in a box-shaped shell-type body, which has a pair of internal housings, a first housing (2) for disinfectant tablet (PD) and a second housing (3) for chlorine tablet (PC). Said housings (2 and 3) are open at the top and arranged side by side in the box body of the device (1), the first housing (2) having a lower water outlet (2a) for the flow of water with disinfectant (AD). The device (1) is closed at the top by a tight-fitting lid (11) that covers its housings (2 and 3), said lid being either hinged or fitted to the device (1).

[0039]

[0014] Both housings (2 and 3) are positioned close to the front face (1a) of the device (1), maintaining a rear spacing in the housing body. In the new configuration, this rear space receives a first internal channel (4), preferably horizontal, which connects a side water inlet (5), located on the side face of the device body (1), to the rear water inlet (6) of the first housing (2). At a certain coincident point, the aforementioned internal channel (4) has a deviation that connects it to the water inlet (7) of the second housing (3). The aforementioned rear space of the device (1) also has a second internal channel (8), preferably parallel to the first (4), connecting a side water outlet (9), also located on the side face of the device body (1), to the rear water outlet (10) of the second housing (3).

[0040]

[0015] The side water inlet (5) of the first internal channel (4) is for connection to the hose (M1) coming from the float (BO) of the flush tank (CA) and may have a connector nozzle (not shown). The side water outlet (9) of the second internal channel (8) is for connection to the hose (M2) for chlorinated water outlet (AC) and may also have a connector nozzle (not shown).

[0041]

[0016] In this configuration, therefore, the rear internal channels (4 and 8) replace the old external flute of the previous configurations of the device, performing the same function, but with added technical advantages in improving its construction, manufacturing, installation and use.

[0042]

[0017] The water outlet (2a) of the first housing (2) is preferably positioned outside the latter, in a channel or duct (2b) also located in the rear space of the device body (1) and connected to said housing (2) by a channel or opening (2c). This configuration outside the housing prevents the water outlet (2a) from being blocked by the pellet (PD) or loose pieces thereof, ensuring good water flow indefinitely.

[0043]

[0018] Preferably, each housing (2 and 3) has the floor, where the tiles (PC and PD) are supported, at an incline or slope facing its respective water outlet (2a and 10), to direct the water and avoid unnecessary accumulation.

[0044]

[0019] The cover (11) of the device (1) may be fixed to the device's own box body (1) for tilting or by a tight fit or be fixed to the flush box cover (CA) when there is a modification in this cover for fitting and supporting the device (1). Preferably, the cover (11) of the device (1) has a raised contour (12) coinciding with the upper edges of each housing (2 and 3) to promote an efficient seal when the cover (11) is closed.

[0045]

[0020] As illustrated in figures 8 to 12, the device (1) in its new arrangement includes an external clip-on connector element (13), this being a centrally hollow tubular body, equipped with an external upper inlet connector nozzle (14) for connection to the chlorinated water outlet hose (M2), which extends in an internal channel (15) into the body of the connector (13) and, after bending, is directed downwards to its water outlet nozzle (16), for the flow of chlorinated water (AC). Said connector (13) is manufactured in a diameter such that it allows its fitting onto the end of the overflow pipe (LA) of the flush tank (CA) and preferably adopting a clip-on element for a firm and stable fit to the latter.

[0046]

[0021] The outlet nozzle (16) of the connector (13) is preferably positioned below the tubular body, i.e., extending beyond its lower edge. Internally, the body of the connector (13) adopts a base (17) that supports and projects downwards a clipping stop (18), preferably rectangular in shape and equipped with friction ribs (not shown) which remains positioned close to the inner wall of the tubular body, so as to allow the tight insertion of the overflow pipe (LA) of the flush tank (CA). Said clipping stop (18) extends beyond the lower edge of the tubular body so that its total length allows a slight deformation due to pressure when the overflow pipe (LA) is inserted.On its upper edge, the tubular body of the connector (13) adopts an annular stop (19) to receive between it and the base (17) a round foam (20), of dedicated sponge type, inserted by said annular stop (19) and limited laterally by the inner walls of the connector body (13).

[0047]

[0022] The device (1) defined herein may adopt any means of fixation already provided for in previous devices defined by the same inventor, such as gluing, claw support, support adapted to the flush tank lid (CA), screwing to the flush tank (CA) or any other possible, with or without modifications to the toilet bowl (VA) and its flush tank (CA). That is, the characteristics of this new constructive arrangement allow any coupling configuration of the device (1) to the flush tank (CA) identified in its previous counterparts. It also allows the device (1) to be fixed in this way to any internal or external part of the flush tank (CA).

[0048]

[0023] Finally, as illustrated in figure 16 and detail B, the device may have an optional configuration (30) where the external connector (13) is attached below to the body of the device (1), preferably just below the second housing (3) of the latter, where the water inlet of the connector (13) is the same water outlet channel of said housing (3). Installation and use:

[0049]

[0024] According to figures 13 to 17, this new arrangement applied to the sanitizing device (1) allows its installation, by any means of fixation provided for in its prior inventions by the same inventor, without external components, such as the flute, which could hinder handling.

[0050]

[0025] After fixing the device ( 1) by any possible means, and in any position relative to the flush tank (CA), a first hose (M l) will connect the float outlet (BO) of the flush tank (CA) to the side water inlet (5) of the first internal channel (4) of the device ( 1) to allow clean water (AL) to enter the housings (2 and 3) through their respective inlets (6 and 7).

[0051]

[0026] In parallel, the connector element (13) is fitted by pressure into the overflow pipe (LA) of the flush tank (CA), stabilized by the pressure of the clipping stop (18) and the internal walls of its tubular body, as illustrated in figure 17 and its detail C. With this, a second hose (M2) will connect the lateral water outlet (9) of the device (1) to the inlet (14) of the connector (13), allowing the flow of chlorinated water (AC) from the second housing (3), through its outlet (10), directly into the overflow pipe (LA), without the hose coming loose and without water escaping, in an action controlled and stabilized by the connector (13). In this action, and throughout the operation of the device (1), the foam or sponge (20) of the connecting element (13) ensures the blocking of the exit of gases resulting from the action of chlorine, improving the installation, a better finish of the assembly and preventing damage to the flush tank (CA) by splashes of chlorine or excess gases.At the same time, this sponge (20) allows water to enter the overflow pipe in case of an internal leak due to a malfunction of the float (BO).

[0052]

[0027] As is normal, the disinfectant water (AD) automatically mixed in the first housing (2) of the device (1) falls by gravity into the flush tank (CA) through its respective outlet (2a) for disinfection of the bowl (VA) on the next flush.

[0053]

[0028] When the device is optionally configured (30), its installation is further simplified, simply attaching the connector (13) to the overflow pipe (LA), which already provides support for the body of the device (1), followed by connecting the first hose (M1) from the float outlet (BO) to the side water inlet (5). In this configuration, therefore, the chlorinated water (AC) falls from its housing (3) directly onto the connector (13), directing it to the overflow pipe (LA) without the need for connection via the second hose (M2).
