CONSTRUCTIONAL ARRANGEMENT APPLIED TO A WATER TANK FILTER WITH ATTACHED FLOAT

Description

/ 7 Construction arrangement applied to a water tank filter with an attached float. TECHNICAL FIELD

[001] This utility model patent application pertains to the sanitation and water supply segment, and refers more specifically to a filter with or without charcoal with an attached float, which is notably designed to be installed inside water tanks and cisterns, more precisely at the water inlet, where the passage is made from the water distribution network or own source (artesian wells, rain, etc.) to the user's plumbing, a place where conventional floats and valves are commonly placed.

[002] The solution uses a floating component coupled to the filter element, ensuring control of the filtered water flow, operating autonomously according to the water level. Furthermore, it has low-complexity elements, facilitating the replacement and ecological disposal of the refill, allowing installation and maintenance by the user themselves, without the need for technical support or high costs for replacing parts. It does not contain iron components, unlike existing ones, which eliminates the risk of rust. HISTORY OF THE TECHNIQUE

[003] Historically, rudimentary methods of water collection and storage were used by civilizations for consumption and irrigation. The use of water filtration devices only began to gain more prominence with the evolution of hydraulic engineering, especially in the Modern Age, when cities began to expand their water supply infrastructures.

[004] During the 19th century, the development of water treatment and filtration technologies became essential due to population growth and the need to ensure water potability. Activated carbon filters, for example, Petition 870240109531, dated 12 / 23 / 2024, page 5 / 20 / 7, for example, began to be used to remove impurities and improve water quality.

[005] Later, water tanks became more common, both in homes and in buildings, serving to store treated water and ensure its continuous supply, especially in areas with distribution problems.

[006] Despite advances, the use of water tanks and filters presents several challenges and problems. Water tanks can be vulnerable to contamination if they are not properly maintained, such as the accumulation of dirt and the development of bacteria.

[007] In addition, the lack of periodic maintenance can lead to problems such as blockage, leaks, and even degradation of the quality of the stored water.

[008] Finally, increased urbanization and water scarcity make the issue even more critical. The use of water tanks and filters, while essential for water distribution and quality, requires constant monitoring, investment in more advanced purification technologies, and, above all, raising public awareness about the importance of maintaining and using these networks responsibly. State of the Art Analysis

[009] Research conducted in specialized databases revealed documents related to water tank filters, such as document no. MU 8602705-0, which deals with a FILTER FOR RETAINING IMPURITIES AT THE INLET AND OUTLET OF THE WATER TANK. This filter is composed of independent parts that together form the filter body: two junctions (1), two pieces of pipe (2) welded together, two weldable reducers (3), a weldable sleeve (4), and a metal filter (5). As seen in the exploded view of Figure 01, the filter manufacturing process consists of internally welding a pipe (2) to the junction (1) and internally to the reducer (3), welding the reducer internally to the sleeve (4), inserting the metal filter (5) inside the sleeve in the protrusion (6) it has, closing the other end with another weldable reducer (2) and the junction (1), forming a single body. The joints can be opened with a thread, as it is... Petition 870240109531, dated 12 / 23 / 2024, p. 6 / 20 / 7 composed of several parts: one welded to the pipe which is male (7), which has the external thread, the sealing rubber (8) which is in a recess of the male part, the interior of the joint (9) and the female part (10) of the joint which has the internal thread, and holds all the components to the male part (7). In Figure 02 we can see that this piece can be made in a single body that can be extruded or blown, provided it has a specific shape or mold. Only the threaded joints (1) could be inserted later. In Figure 03 we have a semi-filter, with the same components as the complete filter, which is used to prevent small animals such as spiders, lizards, bats or mice from entering the water tanks through the pipe called the overflow pipe, which is the water overflow when there is a defect in the tank's float.Small animals enter, but are unable to get out due to the darkness or the water itself, so they drown and die, leaving their remains inside the box. The water can then be used for bathing, cooking, or even drinking.

[010] Document No. MU 8702712-7 concerning a WATER TANK FILTER, a Utility Model patent, which comprises an elongated and round filter 1, with a plastic coating that allows the passage of water 2, equipped with a fixed nozzle-shaped opening for water inlet 3 and a movable nozzle-shaped opening for water outlet 4, both openings with threads where they will be coupled to a threaded coupling terminal 5, allowing the filter to rotate at the outlet 4, without moving the fixed inlet 3, providing easy handling during installation.

[011] Although we find the present documents available on the market, which are in the same market segment and perform their respective functions, the proposed solutions do not present the same constructive elements, as is the case of the floating component. The absence of a float inside a tank or water tank implies a supply without level control, causing burden to the user by allowing the flow of unfiltered water.

[012] Document No. CN220424748 concerning a FLOATING BODY FILTER utility model provides a floating body filter, related to the technical field of filters, the floating body filter includes a support device, Petition 870240109531, dated 12 / 23 / 2024, page 7 / 20 / 7 drum filter device and floating body device, both ends of the drum filter device are detachably provided on the support device by means of a U-shaped connection subassembly, the floating body device is connected to the drum filter device by means of the U-shaped connection subassembly. The floating body device is detachably provided on the support device by means of a screw connection assembly.According to the floating body filter, the floating body filter can float on the water surface by means of the floating body device. The roller filtering device and the floating body device can be disassembled and assembled using the U-shaped connection assembly and the screw rod connection assembly. Disassembly and assembly are convenient, product assembly and subsequent maintenance are facilitated, and, meanwhile, in the practical application process, the floating body filter can float on the water surface. The roller filtering device and the floating body device with corresponding specifications can be selectively assembled according to actual requirements; the structure is flexible and the application range is wide.

[013] Although the present model makes use of a floating body, the document promotes a complex constructive arrangement, the assembly of which may cause harm to the user in case of malfunction, requiring expenses for repairs and a specialized maintenance team, hindering adequate water supply.

[014] Thus, it is a fact that the documents cited in the paragraphs above, despite belonging to the same field of application, do not present any of the characteristics of the object now improved, thus guaranteeing that it meets the legal requirements for patentability. BRIEF DESCRIPTION
