Description

Technical Field

[0001] This invention belongs to the field of shoe washing machine technology, specifically, it relates to a fully automatic shoe washing machine that can be embedded in the floor. Background Technology

[0002] Existing standing, walk-through shoe washing machines have limitations. Because they need to support the weight of a person, the fixed support frame prevents the cleaning of dust on its surface and the shoe soles in contact with it. Secondly, the water-soaked brushes splashing water during the washing process can easily damage trouser cuffs and shoe uppers. Furthermore, most roller shoe washing machines use absorbent rollers or cotton pads to remove moisture left on the soles, or they use a continuous water storage method. The rollers cannot reach the stains in the crevices of the soles, and the wastewater from the washing cotton pads or water storage area is prone to mold growth and odor during prolonged rainy seasons. Summary of the Invention

[0003] To address the shortcomings of the existing technology, the present invention aims to provide a fully automatic, floor-mounted shoe washing machine. This machine features a simple and ingenious structure, enabling rapid cleaning of shoe soles while preventing wastewater splashing during the washing process. Furthermore, it boasts a controllable size, saves water and electricity, and can be embedded in the floor to maintain floor flatness, making it suitable for homes, shopping malls, factories, and other locations. Its integrated encapsulation design also allows it to be placed above ground.

[0004] The technical solution of the present invention is described in detail below.

[0005] An embedded, fully automatic shoe washing machine includes an inflatable water-resistant baffle layer, a shoe sole support frame, a gear track, and a drainage trough. The inflatable water-resistant baffle layer is a hollow airbag structure, positioned above the shoe sole support frame. The shoe sole support frame includes a sleeve, a steel column, and a steel square frame. The sleeve is fitted onto the steel column, and the steel column is fixed to the steel square frame. Electric push-pull rods are connected to both sides of the steel square frame. The gear track is positioned below the shoe sole support frame, with spare tracks on both outer sides for parking a cleaning brush rack and a dry wiping rack, respectively. The cleaning brush rack is equipped with brushes and spray nozzles, while the dry wiping rack is equipped with a wiping cloth and a water suction port. A drainage trough is located below the gear track. During operation, the shoe rests on the sleeve. After a seal check, the airbag inflates and wraps around the edge of the shoe sole. The cleaning brush holder moves on a gear track, driving the cleaning brush holder and dry wiping holder. This, combined with water spraying from the nozzle and brush scrubbing, cleans the sole and sleeve. The suction port and brush work together to remove and dry any remaining moisture from the sole and sleeve, achieving a thorough cleaning. After one cleaning cycle, the electric push-pull rod moves the steel frame and steel column back and forth, causing the sleeve to rotate and clean any areas not cleaned in the first cycle.

[0006] In this invention, the airbag is provided with a cover plate above the inflatable water-proof baffle layer, and the cover plate is designed to be multiple pieces or one piece depending on the physical installation position.

[0007] In this invention, a steel square frame is installed on a support frame, and a steel square frame slide groove is provided on the support frame in the direction of movement of the steel square frame.

[0008] In this invention, motors are installed inside the dry wiping frame and the cleaning brush frame, respectively, with transmission wheels and gear tracks mounted on the motor shafts. A central gear is installed at the top; four rollers are set around the central gear to support the steel frame, so as to maintain balance and reduce the rotational resistance of the gear; when working, the motor rotates to drive the transmission wheel, which in turn drives the central gear and the track gear on the gear track that meshes with the central gear to rotate, so that the dry wiping frame and the cleaning brush frame move along the gear track.

[0009] In this invention, the gear track has meshing teeth and guides. The gear track consists of multiple parallel tracks, or a single track formed by connecting multiple parallel tracks end to end through several circular arc tracks. The end of the gear track has a damping block. During operation, multiple cleaning brush holders and multiple dry wiping holders move on multiple parallel tracks to achieve parallel washing and parallel drying; or a cleaning brush holder and a dry wiping holder move along a gear track formed by a single track to perform washing and drying.

[0010] In this invention, the spray head is connected to the water pipe, and the water pipe is connected to the cleaning and pressurizing pump; the water inlet is connected to the water suction pipe, the sewage suction pump, the sewage discharge pipe, and the drainage ditch.

[0011] In this invention, the brush is a self-rotating brush, which is mounted on a cleaning brush holder via an adjustable height rotating shaft. The rotation of the brush is driven by a rotary motor. The brush bristles and brush head are designed as an integrated unit to prevent dirt accumulation in the gaps of the embedded brush head. The shape of the brush head conforms to the curvature of the shoe sole and the sleeve, so that the sleeve can be cleaned while cleaning the shoe sole. The bristles of the brush are made of non-absorbent material, and the bristles are fine, dense and long, forming a capillary structure between the bristles.

[0012] In this invention, the bottom of the drainage trough is arc-shaped, and a sewage outlet is set in the center of the arc-shaped bottom. A track support is set inside the drainage trough, and the upper part of the track support is connected to the bottom of the gear track.

[0013] In this invention, multiple air inlets and outlets are staggered and arranged on the drainage trough. A fan and drying heating wire are installed outside the air inlets, and a baffle plate is provided at each air inlet. Baffle plates can also be installed at the air outlets. Air flows independently through the inlets and outlets.

[0014] In this invention, the entire internal surface of the shoe washing machine is coated with a hydrophobic material.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The shoe washing machine of the present invention has a simple structure and is easy to operate. It can clean every corner of the shoe sole and the shoe washing machine frame, and brush over every part of the shoe sole and contact with the shoe sole, so as to achieve quick drying and cleaning of the shoe sole and the inside of the shoe washing machine and prevent mold growth. The shoe washing machine of this invention has a thin overall thickness, which can be embedded into various floor structures such as ceramic tiles, wooden floors, and underfloor heating to ensure a flat floor. It is suitable for homes, shopping malls, factories, etc. Attached Figure Description

Detailed Implementation

[0026] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1-8 As shown, the present invention provides a fully automatic shoe washing machine that can be embedded in the ground, which includes an inflatable water-proof baffle layer 1, a shoe sole support frame 3, a dry wiping frame 4, a cleaning brush frame 5, a gear track 9, a track support 93, and a drainage trough 9.

[0028] Inflatable water-resistant baffle layer 1: Primarily used to prevent water from seeping into the shoe edges. Inflatable water-resistant baffle 1 employs a hollow airbag structure with a cover plate on top. Depending on the physical installation location, the cover plate can be designed as multiple pieces or a single piece. Before operation, the airbag is empty, and the cover plate is placed over the shoe washing machine. During operation, the cover plate opens, the shoe falls into the hollow section, and the airbag is inflated by a small air pump to enclose the shoe's bottom edge, preventing soiling of the trouser legs and shoe uppers. After the shoe is removed, inflation continues to seal the shoe placement area, facilitating cleaning of the shoe washing machine's interior. After use or self-cleaning, the air in the airbag is sucked out, the cover plate is replaced, and the ground returns to its normal level.

[0029] The shoe sole support frame 3 includes a support frame, a steel square frame 33, steel columns 32, and a sleeve 31. The sleeve 31 is fitted onto the steel column 32, but there is no connection between the sleeve 31 and the steel column 32. The steel column 32 is fixed to the steel square frame 33. Electric push-pull rods 2 are connected to both sides of the steel square frame 33 to drive it to move back and forth. The steel square frame 33 is installed on the support frame, and the support frame has steel square frame grooves along the direction of movement of the steel square frame. The shoe washing machine is equipped with sensors that automatically detect when shoes fall onto the sleeve, such as gravity sensors, lasers, and ultrasonic sensors. When a shoe falls onto the sleeve 31, it is cleaned. The electric push-pull rod 2 drives the steel square frame 33 to move back and forth. When the steel column 32 moves, the friction between the sole and the sleeve 31 will cause the sleeve 31 to rotate. When the moving distance of the steel square frame 33 is set to half the diameter of the sleeve 31, the upward-facing side of the sleeve 31 will face downward, and the uncleaned part of the sole will also separate from the sleeve 31 for cleaning. The steel material used in the sole support frame 3 can be replaced with alloy, carbon fiber, hard plastic, or other materials.

[0030] Gear track 6: Gear track 6 is a continuous track, formed by connecting several parallel straight tracks end to end via several circular arc tracks. Gear track 6 is located below the shoe sole support frame 3. Spare tracks are provided on both outer sides of the track for alternately parking the dry wiping brush frame 4 and the cleaning brush frame 5. The height of the brush 51 on the cleaning brush frame 5 is adjusted by an adjustable height rotating shaft 53. The hollow pipe 54 contains water pipes and wires. Water is supplied to the water pipe by a pressure pump 7 (if water can be sprayed out, the pressure pump 7 can be omitted), and then enters the water spray head 52. The water pipe can be directly connected to the water input. The water spray head 52 works in conjunction with the brush 51. The water spray head 52 works before the brush 51. Once the cleanliness is achieved, the water spraying stops, and the brush 51 stops rotating. During the brushing process, the wastewater generated flows downwards under gravity and converges, then is discharged through the drain outlet 94. The brush 51 features an integrated bristle and brush head design, replacing traditional embedded bristle brushes. This prevents water from seeping into the embedded groove of the brush head, thus preventing mold growth. Driven by a motor, the brush head 5 rotates rapidly around its center, and the bristles of the brush 51 spread and interlaced along the center, ensuring thorough cleaning of the area directly opposite the brush. The edge of the brush 51 can cover the sleeve 31, with slightly shorter bristles at the edge for easier cleaning of the sleeve 31. A stain sensor at the bottom of the brush 51 detects water flowing onto it, indicating whether it is properly cleaned. The brush 51 is fixedly mounted on a cleaning brush holder 5, which houses a sealed motor 55. A multi-stage transmission gear 56 is mounted on the motor shaft, driving a central gear 57 located below the center of the cleaning brush holder 5. During operation, the motor 55 drives the multi-stage transmission gears, ultimately driving the central gear 57, which meshes with the track gear 61 on the gear track, allowing it to move along the gear track. Four rollers 58 are also provided around the gear core of the track. These rollers 58 support the cleaning brush frame 5 and maintain its balance, while also reducing the rotational resistance of the gear. Continuous or discrete guide blocks 62 are provided on the gear track. These guide blocks are achieved through protrusions on both sides of the gear, keeping the cleaning brush frame 5 moving along the center of the gear track and preventing the track gear from deviating from the track. Damping blocks 63 at the end of the track provide buffering and stopping. After the cleaning brush frame 5 moves along the track once, the telescopic rod pushes the steel square frame 33, causing the sliding sleeve 31 to slide half a diameter away. Due to the friction with the sole of the shoe, the unwashed (upward-facing) sleeve 31 turns downward, exposing the unwashed sole for continued cleaning. The gear track provides a sturdy support, is not easily deformed, and is corrosion-resistant, ensuring even force on the brush. The vacuum suction port 41 and the brush 42 are installed on the dry wiping frame 4. The suction port 41 absorbs water under low pressure. Water enters the water collection device inside the wastewater pump 8 through the suction pipe 71. The water in the water collection device can flow back to the drain port 94 below the shoe washing machine through the downward-sloping drain pipe 72. The brush 42 is located on one side of the suction port. The dry wiping frame 4 moves using the same gear meshing method as the cleaning brush frame 5. The brush 42 is installed on the dry wiping frame 4. The bristles of the brush 42 have an ultra-fine diameter and tiny spacing. They can be arranged in a uniform array or randomly staggered. The fine and dense bristles form a capillary effect, absorbing the residual water left in the depressions of the shoe sole.

[0031] The above-mentioned movement of brush 51 and brush 42 is achieved by the cooperation of gear track, track gear 61, central gear 57 and transmission wheel 56, based on the cooperation of gear-type power wheel and gear track; a roller brush can also be used to replace the existing brush 51 and brush 42.

[0032] In another embodiment, the gear track 6 can be designed as multiple parallel tracks, with each track equipped with a cleaning brush holder 5 and a dry wiping holder 4. Damping blocks are located at both ends of each track. The dry wiping holder 4 is located in a dedicated parking area at one end of the gear track, and the cleaning brush holder 5 is located in a dedicated parking area at the other end of the gear track. Each cleaning brush holder 5 is equipped with a water spray head 52 and a brush 51. Multiple cleaning brush holders 5 can move forward and backward, performing brushing work in parallel. Multiple water spray heads 52 distribute water from a single water pipe. After brushing, the brush holders are removed from the sole working area and moved to one end of the track. Each dry wiping holder 4 is equipped with a water suction port 41 and a brush 42. All water collected by the water suction ports 41 is channeled to a single water pump. The brush 42 then wipes away any remaining water from the sole in parallel. After wiping, the brush holder returns to its parking area.

[0033] The gear track is supported by track support column 93, which is connected to the center of the gear track. The isolation space provides ventilation and isolation from sewage. The track support column 93 has an arc-shaped bottom, and the sewage outlet 94 is located in the center of the arc-shaped bottom.

[0034] After the shoes are removed, the air bladder continues to inflate, cleaning the bladder and drying it with air. The air inlets 91 and 95 are staggered to allow airflow through every corner of the shoe washer. In dry weather, heating is not required; only ventilation is needed, allowing the shoe to be ready for the next use. In case of continuous rainy weather, a heating and drying function is activated, blowing hot air. The dry air flows along the water-absorbing brush pipes. To prevent water from flowing backwards or splashing onto the fan and heating elements, a water baffle 92 is installed at the air inlet 91. The baffles are arranged in an arc shape, providing both water protection and ventilation. The fan and drying heating elements are located on the outside of the air inlet 91, i.e., the exterior of the shoe washer. A baffle can also be installed at the air outlet 95, allowing independent airflow at the air inlet 91 and outlet 95.

[0035] The device's embedded chip control board can connect to intranets, internet, and mobile phones, integrating into a whole-house smart control system. It is compatible with both human-loaded and non-human-loaded cleaning functions. Because the inflatable airbag baffle restricts shoe movement, it can fix the shoe's position when no weight is applied, enabling non-human-loaded cleaning.

[0036] Install the inflatable airbag and check for a tight seal. If the seal meets the standard, the work can begin. If the seal does not meet the standard, the detected problem will be displayed.

[0037] A steady-state operating parameter judgment mechanism is set, and the circuit has upper limits for withstand voltage and current. Operation stops when the total current, voltage, or sealing exceeds the threshold. Operation stabilizes when all indicators are within the threshold range.

[0038] like Figure 9 The diagram illustrates the workflow of the shoe washing machine. When not in use, the machine has a cover plate on top, the color and material of which match the interior design. The power switch is off; when needed, it can be manually turned on. An intelligent sensor can be used to detect if someone enters the machine. The cover plate can be set to open only when someone enters the room, or manually. One-way triggering means the cover opens only when someone enters the room; it remains closed by default when someone leaves. It can also be set to open when someone enters or leaves the room. The machine activates the shoe sole cleaning function only after a confirmation of entry and exit. Upon detecting a shoe, the airbag inflates, a seal check is performed, and cleaning begins. A wastewater sensor detects wastewater feedback parameters and determines the forward speed. After the brushes have cleaned once, the embedded chip controls the electric push-pull rod to push the steel frame 33, causing the sleeve 31 to reverse and clean areas not cleaned in the first pass. After cleaning, the brushes wipe the shoes, and the machine rotates to wipe again. Once cleaning and wiping are complete, the machine notifies the user to remove the shoes.

[0039] The shoe washing machine of this invention uses rollers 59 to support a steel frame that moves along a gear track, cleaning the soles of shoes and every corner of the machine's support frame. An integrated, self-rotating, staggered brush, combined with a micro-bristle absorbent wipe, can brush every part of the sole and the area in contact with it. A bristle wipe 42 replaces absorbent cotton to wipe away moisture from the crevices of the sole, and is easy to clean and dry. A gear-type power wheel and a gear track, combined with a circular support wheel, ensure the smooth movement of the brush 51. The drainage system uses an arc-shaped design, with hydrophobic material sprayed onto the inner wall of the machine and the inside and outside of the pipes, and vertical brushes and drains. The entire device features a separate ventilation duct design, preventing air exchange with the ground and avoiding backflow of cleaning air into the room. The air inlet 91 and outlet 95 provide staggered ventilation, blowing air to every corner of the machine's interior. A water-resistant baffle prevents moisture from contaminating the ventilation or heating devices while allowing airflow. It also features drying and disinfection functions, making it suitable for rainy seasons.

[0040] The above are preferred embodiments of the present invention, but are not limited thereto. Those skilled in the art can easily understand the spirit of this application based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this application, they are all within the scope of patent protection.
