1 / 9 SHOE WASHING SYSTEM BY MOUNTING ON AXLES

[001] Electromechanical equipment for the sanitization and maintenance of personal and household items, with emphasis on footwear; automatic cleaning systems and electronic control applied to conservation processes; compact and portable machines for domestic and professional use; automation technologies aimed at optimizing the cleaning process; sustainable solutions with the reuse of water resources in automated cleaning equipment.

[002] Currently, in the state of the art, there are several pieces of equipment designed for cleaning footwear, ranging from manual solutions to automatic machines. Many of these devices use rotating brushes to remove dirt and stains, but they are generally designed for industrial use, being large in size and having low adaptability for domestic or small-scale professional use. In addition, most existing systems do not integrate advanced electronic control functionalities to customize parameters such as time, temperature, and detergent dosage, limiting the efficiency and flexibility of the cleaning process.

[003] Another common limitation is the absence of systems that promote water reuse, resulting in higher consumption and waste of water resources. Equipment that incorporates dry cleaning methods, such as steam spraying, is rare and generally restricted to specialized industrial solutions, not accessible to the average consumer. Furthermore, many models have difficulty accommodating different sizes and types of footwear, compromising the uniformity of cleaning and the preservation of materials.

[004] Despite the existence of shoe cleaning machines on the market, the state of the art lacks a solution that provides greater cleaning efficiency, while also allowing for a compact, automated and sustainable solution that combines programmable control, adaptability to various models and sizes, and technologies for optimizing water consumption. Petition 870260000325, dated 05 / 01 / 2026, page 3 / 18 2 / 9 catering to both domestic and professional, and even industrial, use in an efficient and safe manner.

[005] The development of the present utility model was motivated by the limitations of existing equipment for cleaning footwear, which is generally bulky, poorly adaptable to different sizes and models, and has high water consumption without adequate resources for reuse, and does not allow the footwear to be efficiently cleaned inside, and also, the cleaning / hygiene on the outside is not homogeneous. In addition, the absence of programmable controls in traditional systems limits the customization of the cleaning process, reducing efficiency and increasing wear and tear on materials.

[006] The proposed model overcomes these shortcomings by integrating a compact automated system with a perforated rotating support that accommodates various footwear, and rotating bristles driven by electric motors that promote gentle and uniform cleaning. The use of embedded electronics allows for programmable adjustment of essential parameters such as washing time, temperature, rotation speed, and detergent dosage, offering greater control and efficiency in the process.

[007] Another important feature is the hydraulic system that allows for continuous circulation and reuse of water, as well as the option of dry cleaning by steam spraying, expanding the possibilities of use and reducing water consumption. These improvements make the equipment more economical, versatile, and suitable for both domestic and professional use, providing effective cleaning and preservation of footwear with less environmental impact.

[008] The device in question comprises a closed container with capacity for one or two pairs of shoes, which are positioned internally by means of a hollow and perforated rotating support (element 4 Figure 3 described as an elongated and curved object, with several small circular perforations distributed along its surface, such element Petition 870260000325, dated 05 / 01 / 2026, page 4 / 18 The main motor (3 / 9) performs rotations, with its base fixed to a support (represented by a circular shade), which allows water circulation. This support, adaptable to the size of the footwear, rotates at low speed, coupled to a common shaft or a shaft derived from the main motor.

[009] The washing is carried out by rotating bristles (Element 3 - Figure 1 - Front view of the equipment with indication of the elements), which safely penetrate the structure of the footwear, promoting cleaning without damaging the material. The brushes are driven by an electric motor (Element 5 - Figure 1 - Front view of the equipment with indication of the elements), which can operate independently or together with a differential (Element 6 - Figure 1 - Front view of the equipment with indication of the elements) to drive the rotating support (Figure 1 - Front view of the equipment with indication of the elements).

[010] The hydraulic system consists of a motor-pump assembly (element 8 - Figure 1 - Front view of the equipment with indication of the elements), which pressurizes the water and circulates it through hoses or pipes (element 9 - Figure 1 - Front view of the equipment with indication of the elements), and water can be reused through internal filtration. The system can also heat the water.

[011] The machine also features embedded electronics (element 1 - Figure 1 Front view of the equipment with indication of the elements), allowing the setting of washing time, water temperature, activation of the steam system (optional) and complete operating cycles, as well as control of the input and output of specific detergents.

[012] The equipment may include an additional configuration with dry cleaning, by steam spraying onto the rotating support, in a separate container. The structure is designed to be compact and portable, with approximate dimensions of 400 mm x 400 mm x 550 mm.

[013] The graphic representations of this model are shown in the attached set of drawings, with the following figures: Petition 870260000325, dated 05 / 01 / 2026, page 5 / 18 4 / 9 • Figure 1 - Front view in section of the equipment with the indicated internal elements. Figure 1 shows the front view of the shoe washing equipment, highlighting the internal distribution of the mechanical, electrical and hydraulic components. In the upper portion of the container body (1) are the elements responsible for the washing process. Three rotating assemblies are visible: a central brush composed of rotating bristles (3) and two hollow and perforated supports (4) intended for fitting the shoes. Both the bristles and the side supports are mounted on independent vertical shafts, all with rotational movement. The mechanical transmission is carried out by the electric motor (5), coupled to the rotation distribution and derivation bearing (6), which redistributes the torque to the different upper rotating shafts, ensuring the simultaneous operation of the bristles and supports.In the lower right part of the structure is installed the motor pump (7), responsible for recirculating the washing fluid. The motor pump is connected to a set of filters and hydraulic accessories (8), which perform the filtering and stabilization of the flow. The transport and conduction of the fluid are carried out by hoses and ducts (9 and 10), intended for drainage, reuse and hydraulic supply of the system. The body of the container (1) also houses, in its own internal compartment, the service panel, the power electronics and the control display, responsible for the operational control of the equipment. • Figure 2 - Side view of the compartment with the rotating shoe supports positioned. Figure 2 shows a side view of the equipment, highlighting the distribution of mechanical and hydraulic components along the depth of the system. In the upper region, the washing compartment is observed, where the rotating assembly is installed, consisting of a perforated shoe support and rotating bristles, both mounted on a vertical axis. These elements perform rotational movement from the torque redistributed by the distribution and derivation bearing (11), located in the lower intermediate portion of the equipment. Below the washing area is the technical compartment, responsible for hydraulic circulation and the operation of the Petition 870260000325, dated 05 / 01 / 2026, page 6 / 18 5 / 9 auxiliary systems. The filters and hydraulic accessories (10) are located here, responsible for retaining particulate residues and stabilizing the flow of the washing fluid. The fluid is transported by a set of hoses and ducts, intended for drainage, reuse and hydraulic supply of the system. These conduits connect the motor pump and filters to the reservoir and the upper compartment, ensuring continuous fluid recirculation. The arrangement shown in the side view allows visualization of the relationship between the rotating shafts, the redistribution bearing, and the entire hydraulic circuit, highlighting the functional organization and interconnection of the internal elements of the washing equipment. • Figure 3 - Technical detail of the rotating support with holes. Figure 3 shows a detailed view of element 4, corresponding to the hollow and perforated support used to fit the footwear inside the equipment. The support has an elongated and curvilinear shape, with multiple perforations distributed along its outer surface. The element is hollow, allowing the internal passage of liquids or vapor, which are distributed through its perforations during the washing or sanitizing process. The support is mounted on a vertical axis with rotational capacity, enabling the rotary movement indicated by the graphic representation in the figure. The lower part of the support is coupled to the drive assembly, which transmits the torque necessary for its continuous rotation.This rotation, combined with the injection of fluid through the perforations, contributes to the internal and external cleaning of footwear placed on the element.

[014] Furthermore, the present utility model refers to an automated system for sanitizing footwear, especially sneakers, designed to offer efficient, safe cleaning and adaptable to different shapes and sizes of footwear. The equipment consists of a closed container that houses internally a hollow and perforated rotating support (Figure 3 - Detailed view of element 4), intended for positioning the footwear during the washing process. Petition 870260000325, dated 05 / 01 / 2026, page 7 / 18 6 / 9

[015] The rotating support is attached to a central shaft, driven by an electric motor that allows controlled rotation of the support, ensuring that the footwear is uniformly exposed to mechanical and hydraulic actions during cleaning. Attached to the system are rotating bristles, also driven by an electric motor, which promote the gentle removal of dirt and residue, penetrating the weave and surfaces of the materials without causing structural damage.

[016] The hydraulic system comprises a motor pump that circulates water within the container, a heater that raises the temperature of the washing solution to improve cleaning effectiveness, filters that remove solid particles and impurities, and connections that allow for water circulation and reuse. The model also features a dry cleaning option, performed by steam spraying, expanding its functionalities.

[017] The embedded electronics programmably control various process parameters, including washing time, water temperature, brush rotation speed and dosage of specific detergents, allowing the cycle to be customized according to the type of footwear and degree of soiling.

[018] The equipment has a compact and portable structure, making it easy to use in both domestic and professional environments, and is suitable for sneakers, shoes, boots and similar footwear, as well as children's footwear. The combination of mechanical, hydraulic and electronic systems offers an integrated solution that promotes uniform cleaning, preservation of materials and operational efficiency.

[019] This model can be implemented with variations in the construction materials of the container and support, different configurations of motors and bristles (Elements 5 and 3, respectively - Figure 1 - Front view of the equipment with indication of the elements), as well as adjustments to the electronic programming for specific cycles. In addition, sensors can be incorporated. Petition 870260000325, dated 05 / 01 / 2026, page 8 / 18 7 / 9 for monitoring temperature, water level and component wear, ensuring greater control and safety during use.

[020] The container housing the system is approximately 60 cm high by 50 cm in diameter and can be made of acrylic, glass, or AISI 304 stainless steel, ensuring corrosion resistance and durability. The internal rotating support consists of a hollow, perforated structure with dimensions compatible with accommodating shoes of various sizes, constructed of AISI 304 stainless steel or liquid-resistant treated carbon. The central shaft that couples the support is driven by a 12 V DC electric motor with variable nominal torque (3 Nm, for example), allowing for variable controlled rotation (between 10 and 40 revolutions per minute).

[021] The rotating bristles are fixed to movable arms coupled to a 110 / 220 V AC motor with a power of 150 W, designed in flexible polymeric material to promote effective cleaning without damaging the surfaces of the footwear. The hydraulic system integrates a submersible motor pump with a flow rate (of 4 liters per minute), an electric heater (of 500 W) for controlling the temperature of the washing solution, and fine mesh filters for retaining solid particles. The circulation of water allows its reuse during the cycle, optimizing water consumption.

[022] The embedded electronics are based on an XYZ model microcontroller, equipped with an LCD display and a touch-sensitive button interface for programmable parameter selection, such as washing time (from 15 to 60 minutes), temperature (up to 60°C), brush rotation speed, and automatic dosing of specific detergents. Temperature and water level sensors ensure safe and efficient operation, with visual alerts in case of irregularities.

[023] The model constitutes a single integrated technical-functional unit, combining mechanical, hydraulic and electronic systems in a compact and portable structure, specially designed for the automated sanitization of footwear. It does not include independent components or devices with distinct functions, ensuring that the object has a single technical function and Petition 870260000325, dated 05 / 01 / 2026, page 9 / 18 8 / 9 defined three-dimensional body.

[024] The utility model can be implemented in various constructive forms, adapting to the specific needs of domestic, professional or industrial use. The preferred embodiment consists of a compact, portable and integrated device, composed of an acrylic or stainless steel container with approximate dimensions of 60 cm in height and 50 cm in diameter, a perforated rotating support in stainless steel or carbon steel and a system of rotating polymeric bristles driven by specific electric motors (Elements 3 and 5, respectively - Figure 1 - Front view of the equipment with indication of the elements), for controlled rotation. The structure is designed to accommodate various footwear, including sneakers, shoes and boots, ensuring uniform cleaning and preservation of the materials.

[025] Among the possible variations, different volumes stand out, impacting the size, capacities, and power of the motors for the rotating support and brushes, which can be adjusted according to the volume and type of footwear to be sanitized. The hydraulic system can vary in the capacity of the motor pump, heater power, and filter types, allowing customizations for greater efficiency or reduced water consumption. The embedded electronics can be implemented with microcontrollers of different models, interfaces with LCD or touchscreen displays, and additional sensors for enhanced process monitoring.
