Description

Technical Field

[0001] This invention relates to the field of shoe washing technology, and more specifically, to a shoe washing machine. Background Technology

[0002] As people's living standards continue to improve, their demands for cleaning results are also increasing. Shoes are an indispensable part of people's lives. Due to rapid economic development, the materials used to make shoes have become more diverse, and the styles are becoming more numerous, thus increasing the difficulty of cleaning them.

[0003] The inventor's research revealed that existing shoe washing machines typically use a large-sized inner washing drum with a rotating structure, requiring an additional outer shell. This type of machine is bulky, has a complex internal structure, and occupies a significant amount of space. Furthermore, the double-layered structure of the inner drum and outer shell prevents visualization of the washing process, making it difficult to directly observe the cleaning status of the shoes. Inspection is only possible after the shoes are removed, which is quite inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a shoe washing machine that is smaller in size, simpler in structure, occupies less space, and enables visual monitoring of the cleaning process, allowing direct observation of the cleaning status of the shoes, which is very convenient.

Multiple elastic ribs are spaced apart between the top ring and the base plate. One end of each elastic rib is connected to the top ring, and the other end is connected to the middle of the base plate. The multiple elastic ribs are configured to elastically limit the movement of the shoe body to be cleaned.

[0008] In an optional embodiment, the receiving cavity is further provided with a plurality of cleaning brushes, which are inserted between the inner walls of the rotating bracket and the visible cylinder and are disposed opposite to the spray assembly on both sides of the rotating bracket.

[0010] In an optional embodiment, the shoe washing machine further includes a drying assembly, which includes a drying fan, a heating element, and an air guide sleeve. A hot air vent connected to the receiving cavity is also provided on the side wall of the main body box near the visible cylinder. The hot air vent is configured to correspond to the shoe opening of the shoe to be cleaned. One end of the air guide sleeve is connected to the air outlet of the drying fan, and the other end is connected to the hot air vent. The heating element is located at the air outlet of the drying fan and is configured to heat the air inside the air guide sleeve.

[0011] In an optional embodiment, the drying assembly further includes an ozone generator disposed within the main body housing, with the electrodes of the ozone generator disposed within the air guide sleeve, configured to generate ozone within the air guide sleeve to sterilize the shoe body to be cleaned.

[0012] In an optional embodiment, a UV lamp module is further provided on the side wall of the main body box near the visible cylinder. The UV lamp module is located in the receiving cavity and is configured to perform UV sterilization on the shoe body to be cleaned.

[0013] In an optional embodiment, the side wall of the base is further provided with a reset opening, and a reset cover is detachably provided on the reset opening.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0023] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0024] As disclosed in the background section, the existing shoe washing machine 100 is large in size and has a complex internal structure, requiring a significant amount of space for placement. Furthermore, due to the dual-layer structure of the inner cylinder and outer shell, the existing shoe washing machine 100 cannot provide visualization of the cleaning process, making it difficult to directly observe the cleaning status of the shoes. Observation is only possible after the shoes are removed, which is quite inconvenient.

[0025] Furthermore, the existing shoe washing machine 100 has a single function, which can only achieve the rinsing effect and cannot simultaneously achieve cleaning, drying, sterilization and other intelligent functions, resulting in a low level of intelligence.

[0026] To address the aforementioned problems, this invention provides a novel shoe washing machine 100. It should be noted that, without conflict, the features in the embodiments of this invention can be combined with each other.

[0027] See Figures 1 to 3This invention provides a shoe washing machine 100, which is smaller in size, simpler in structure, occupies less space, and enables visualized cleaning, allowing direct observation of the shoe's cleaning status, which is very convenient. It also integrates automated rinsing, ultrasonic cleaning, drying, and sterilization functions, resulting in a higher level of intelligence.

[0028] The shoe washing machine 100 provided in this embodiment of the invention includes a base 110, a visible cylinder 120, a rotating bracket 130, a main body box 140, a spray assembly 150, and a cover plate 160. The base 110 is placed on the ground. The visible cylinder 120 is disposed on the base 110 and has an inner cavity 121. An opening 122 is provided at the end of the inner cavity 121 away from the base 110. The rotating bracket 130 is rotatably disposed on the base 110 and disposed in the inner cavity 121, and rotates... The bracket 130 is configured to vertically hold at least two shoes 200 to be cleaned; the main body box 140 is disposed on the base 110 and connected to one side of the viewing cylinder 120; the spray assembly 150 is disposed inside the main body box 140 and extends partially into the receiving cavity 121, and is configured to rinse the shoes 200 to be cleaned; the cover 160 is detachably disposed at the loading and unloading port 122; wherein at least a portion of the sidewall of the viewing cylinder 120 is transparent and forms an observation window corresponding to the rotating bracket 130.

[0029] It should be noted that the viewing cylinder 120 can be cylindrical, and the main body box 140 can be rectangular, housing the main control board and related electronic components. The shape of the base 110 matches the shapes of the viewing cylinder 120 and the main body box 140. The rotating bracket 130 is a rotatable structure, thus the cylindrical shape of the viewing cylinder 120 ensures that the distance between the inner wall of the viewing cylinder 120 and the rotating bracket 130 is uniform throughout, which is more conducive to the miniaturization of the overall structure. Two shoes 200 to be cleaned can be vertically placed on the rotating bracket 130. This embodiment of the invention avoids the use of a movable cleaning inner cylinder, employing a single-layer containment method and a vertical placement to accommodate multiple shoes 200 to be cleaned. Therefore, the volume of the viewing cylinder 120 is reduced, resulting in a smaller overall shoe washing machine 100 with a simpler structure and smaller footprint. Furthermore, the viewing cylinder 120 is equipped with an observation window, enabling visual monitoring of the cleaning process and allowing direct observation of the shoe's cleaning status, which is very convenient.

[0030] It is worth noting that the viewing cylinder 120 is fixedly mounted on the base 110, thereby forming an inner cavity 121 that can accommodate the rotating bracket 130. A support plate 119 is also provided on the bottom side of the base 110. The support plate 119 is larger than the base 110, which can increase the support area and improve support stability. The viewing cylinder 120 can be made of a transparent material, such as glass or transparent acrylic, so that the observation window can cover the entire side wall of the viewing cylinder 120, increasing the observation angle and making it more useful for real-time observation of the shoe cleaning process. Of course, in other preferred embodiments of the present invention, the viewing cylinder 120 can also adopt a partially transparent design, thereby forming an observation window on part of the side wall of the viewing cylinder 120 for more targeted observation.

[0031] See Figures 3 to 5 In some embodiments, the spray assembly 150 includes a booster pump 151 and at least two nozzle modules 152. The booster pump 151 is disposed inside the main body box 140 and connected to the multiple nozzle modules 152 via pipes. The multiple nozzle modules 152 are arranged side by side on the side wall of the main body box 140 near the visible cylinder 120, and each nozzle module 152 is provided with a spray nozzle 153, the opening direction of which is towards the rotating bracket 130. Specifically, there may be two nozzle modules 152, which are arranged in a parallel strip on the side wall of the main body box 140 near the visible cylinder 120, and each nozzle module 152 is provided with a vertical spray nozzle 153. The spray nozzle 153 can spray high-pressure water into the receiving cavity 121, thereby rinsing the shoe body 200 to be cleaned on the rotating bracket 130.

[0032] It should be noted that the booster pump 151 can be connected to an external faucet via a pipe, and the pipe is controlled by a solenoid valve. In actual use, after the faucet is turned on, the solenoid valve receives a flushing signal and releases water to the booster pump 151. After the booster pump 151 pressurizes the water, it delivers it to two spray head modules 152. Both spray head modules 152 are fixed, while the rotating bracket 130 can rotate, thereby causing the shoe body 200 to be cleaned to rotate. Subsequently, each surface of the shoe body 200 to be cleaned undergoes high-pressure spray washing through the spray nozzles 153.

[0033] In some embodiments, the rotating bracket 130 includes a base plate 131, a top ring 132, a plurality of support columns 133, and a plurality of elastic ribs 134. A rotating drive member 111 is also provided in the base 110. The rotating drive member 111 is connected to the base plate 131 and is configured to drive the base plate 131 to rotate. The plurality of support columns 133 are arranged in parallel on the edge of the base plate 131 and extend in a direction away from the rotating drive member 111. The top ring 132 is arranged near the pick-up and drop-off port 122 and is arranged opposite to the base plate 131. One end of each of the plurality of support columns 133 away from the rotating drive member 111 is connected to the top ring 132. The plurality of elastic ribs 134 are spaced apart between the top ring 132 and the base plate 131. One end of each elastic rib 134 is connected to the top ring 132 and the other end is connected to the middle of the base plate 131. The plurality of elastic ribs 134 are configured to elastically limit the shoe body 200 to be cleaned. Specifically, the base plate 131 is disc-shaped, and the top ring 132 is annular, with the outer diameter of the base plate 131 matching the outer diameter of the top ring 132. Multiple support columns 133 are evenly distributed along the edge of the base plate 131, preferably three support columns 133 arranged in an equilateral triangle on the base plate 131. The rotation drive component 111 can be a drive motor, and the bottom of the base plate 131 can be connected to the output shaft of the drive motor, allowing the drive motor to rotate the base plate 131, thereby rotating the entire rotating bracket 130. By controlling the speed of the drive motor, the functions of rotational rinsing and spin-drying can be achieved.

[0034] It should be noted that the inner diameter of the top ring 132 needs to be larger than the size of the shoe body 200 to be cleaned, so as to facilitate the insertion of the shoe body. The top end of the elastic rib 134 is fixedly connected to the top ring 132, and the bottom end is fixedly connected to the middle area of ​​the bottom plate 131. Multiple elastic ribs 134 can form a clamping space that can achieve elastic deformation. The shoe body 200 to be cleaned can be inserted into the top ring 132 through the loading and unloading port 122 and placed into the clamping space formed by the elastic ribs 134. The elastic ribs 134 can fix the shoe body 200 to be cleaned. In addition, the size of the bottom plate 131 is smaller than the size of two shoe bodies 200 to be cleaned side by side, so as to ensure that the two shoe bodies 200 to be cleaned are placed vertically and avoid mutual compression and obstruction.

[0035] It is worth noting that the drive motor here can control the rotation speed of the rotating bracket 130. During the rinsing stage, high-pressure water jets can be sprayed through the spray nozzle 153 to rinse the shoe body. At this time, the rotation speed of the rotating bracket 130 is relatively low to ensure the rinsing effect. During the spin-drying stage, the drive motor can drive the rotating bracket 130 to rotate at high speed, thereby generating a large centrifugal force on the shoe body to achieve the purpose of simple spin-drying.

[0036] See Figure 6In some embodiments, a plurality of cleaning brushes 112 are also provided within the accommodating cavity. These cleaning brushes 112 are inserted between the inner walls of the rotating bracket 130 and the visible cylinder 120, and are positioned opposite the spray assembly on both sides of the rotating bracket 130. The cleaning brushes 112 are configured to clean the upper of the shoe body 200 to be cleaned. Specifically, the cleaning brushes 112 can be soft nylon bristles, and each cleaning brush 112 extends vertically. Three long-bristled cleaning brushes 112 can be inserted into the visible cylinder 120. The cleaning brushes 112 can be distributed horizontally with the spray assembly 150. When the right side is spraying, the cleaning brushes 112 on the left side can assist in cleaning the shoe body. Of course, the cleaning brushes 112 are optional components and can be easily removed from the upper opening 122 when not in use.

[0037] It should be noted that the cleaning brush 112 is kept relatively fixed to the visible cylinder 120. Preferably, a fixing groove can be added to the inner wall of the visible cylinder 120 to fix the cleaning brush 112 in the circumferential direction, so as to prevent the cleaning brush 112 from rotating synchronously under the drive of the shoe body and the rotating bracket 130.

[0038] See Figure 4 , Figure 5 and Figure 7 In some embodiments, the shoe washing machine 100 further includes an ultrasonic spray assembly 170, which includes an ultrasonic generator 171 and multiple sets of ultrasonic transducers 172. Multiple sheet metal parts 173 are also embedded in the side wall of the main body box 140 near the visible cylinder 120. The multiple sets of ultrasonic transducers 172 are correspondingly disposed on the multiple sheet metal parts 173 and correspond to multiple shoe bodies 200 to be cleaned. The ultrasonic generator 171 is disposed inside the main body box 140 and electrically connected to the multiple sets of ultrasonic transducers 172. Specifically, there can be two sets of ultrasonic transducers 172, each corresponding to two shoe bodies 200 to be cleaned, and each set of ultrasonic transducers 172 can have multiple transducers, thereby improving the cleaning effect. During actual cleaning, the solenoid valve can release water into the receiving cavity 121 after receiving a water injection signal. When the water level reaches the set value, the ultrasonic washing action begins. The water level set value can be set according to the height of the largest shoe body to ensure that the water level always covers the shoe body. The ultrasonic generator 171 is a low-power, high-frequency generator, and two sets of ultrasonic transducers 172 respectively perform ultrasonic cleaning on the two shoe bodies 200 to be cleaned. An opening is formed on the side wall of the main body box 140, and the sheet metal part 173 is fixed to the opening with bolts and sealed with a silicone rubber gasket. Vibration damping can also be achieved between the bolts and the sheet metal part 173 using silicone gaskets.

[0039] It should be noted that during ultrasonic cleaning, the rotating bracket 130 can be slowly rotated by a drive motor, causing the dirt dislodged by the ultrasonic waves to dissolve in the water, thus achieving a cleaning effect. Furthermore, water can be discharged directly through the spray nozzle 153, or a separate drain valve and pipe can be installed for low-pressure water discharge. In addition, the high-pressure rinsing by the spray assembly 150 and the ultrasonic washing by the ultrasonic spray assembly can be performed separately; that is, the shoe body can be high-pressure rinsed first, followed by ultrasonic washing, which results in a better cleaning effect.

[0040] In some embodiments, the shoe washing machine 100 further includes a drying assembly 180, which includes a drying fan 181, a heating element 182, and an air guide sleeve 183. A hot air vent 123 communicating with the inner cavity 121 is also provided on the side wall of the main body box 140 near the visible cylinder 120. The hot air vent 123 is configured to correspond to the shoe opening of the shoe body 200 to be cleaned. One end of the air guide sleeve 183 is connected to the air outlet of the drying fan 181, and the other end is connected to the hot air vent 123. The heating element 182 is located at the air outlet of the drying fan 181 and is configured to heat the air inside the air guide sleeve 183. Specifically, the drying fan 181 is located in the bottom area of ​​the main body box 140, the heating element 182 can be a heating rod, and the air guide sleeve 183 can be a silicone sleeve, which provides better controllability of deformation and better sealing. After the drying fan 181 is started, air can be drawn in from the back, and the heating rod will generate hot air. The hot air is then transferred to the hot air outlet 123 through the silicone sleeve. The hot air is then transferred to the inner cavity 121 through the hot air outlet 123 and is used to dry the shoe body 200 to be cleaned.

[0041] It is worth noting that the hot air vent 123 dries the shoe opening of the shoe body 200 with hot air, which can quickly and effectively dry the shoe from the inside out. In order to prevent water from entering during soaking, a check valve is provided at the hot air vent 123.

[0042] In some embodiments, the drying assembly 180 further includes an ozone generator 184, which is disposed within the main body housing 140, with its electrodes disposed within an air guide sleeve 183. The ozone generator 184 is configured to generate ozone within the air guide sleeve 183 for sterilizing the shoe body 200 to be cleaned. Specifically, the ozone generator 184 is disposed near the drying fan 181, and its electrodes can be disposed within the air guide sleeve 183 near the air outlet of the drying fan 181. This allows ozone to be generated near the air outlet of the drying fan 181 and delivered to the hot air outlet 123 via the air guide sleeve 183 along with the hot air, generating ozone during drying to achieve sterilization.

[0043] It should be noted that in this embodiment, ozone is used to disinfect the inside of the shoe, while ultraviolet light is used to disinfect the shoe surface and the inner cavity 121. This avoids the proliferation of bacteria inside the inner cavity 121 caused by long-term use, making the shoe cleaner and safer.

[0044] In some embodiments, a UV lamp module 141 is also provided on the side wall of the main body box 140 near the visible cylinder 120. The UV lamp module 141 is located in the receiving cavity 121 and is configured to perform UV sterilization on the shoe body 200 to be washed. Specifically, two UV lamp modules 141 are installed on the side wall of the main body box 140. The power supply can be connected to the main control board inside the main body box 140. The UV lamp modules 141 can be turned on throughout the washing process to achieve the function of UV sterilization.

[0045] See Figure 3 , Figure 4 , Figure 5 and Figure 7 In some embodiments, the side wall of the base 110 is also provided with a reset opening 113, and a reset cover 114 is detachably provided on the reset opening 113. The base 110 is also provided with a drain pipe 115 that communicates with the inner cavity 121. A drain valve 116 is provided on the drain pipe 115. The drain valve 116 is fixedly provided at the reset opening 113 and is detachably provided with a filter mesh block 117. The filter mesh block 117 is exposed outside the reset opening 113 and is configured to filter the wastewater in the drain valve 116.

[0046] In some embodiments, a temperature sensor 185 may also be provided inside the air guide sleeve 183 to accurately measure the temperature of the hot air and feed it back to the heating element 182, thereby adjusting the heating power of the heating element 182 to prevent the hot air temperature from being too high and damaging the shoe body.

[0047] In some embodiments, a water level sensor 142 is also provided inside the main body box 140, which is communicatively connected to a solenoid valve. The water level sensor 142 forms a communication device with the receiving cavity 121 through a pipe. When the water level reaches the soaking water level, that is, after submerging the shoe body, the solenoid valve is closed to stop the water from flowing out.

[0048] In some embodiments, a humidity sensor 118 is also provided at the end of the drain pipe 115 near the visible cylinder 120. The humidity sensor 118 is communicatively connected to the heating element 182 and the drying fan 181. After drying reaches a certain level, the humidity at the drain pipe 115 will also decrease accordingly, and drying can be stopped.

[0049] In some embodiments, a turbidity sensor 143 is also provided in the bottom area of ​​the main body box 140. The turbidity sensor 143 can extend into the receiving cavity 121. If a large amount of contaminants is detected during the water filling and rinsing process, a cleaning cycle can be repeated.

[0050] See Figure 1 and Figure 3 In some embodiments, the cover plate 160 is hinged to the top of the main body box 140, and a metal sensor 161 is provided on the cover plate 160. A corresponding metal sheet 144 is provided on the main body box 140. The metal sensor 161 is configured to sense the metal sheet 144 when the cover plate closes the loading / unloading opening 122. Specifically, the cover plate 160 has a flip-top structure, which can block the loading / unloading opening 122 to prevent cleaning liquid from splashing out during the cleaning process. Furthermore, the metal sheet 144 can be a stainless steel sheet, and the sensing distance between the metal sensor 161 and the stainless steel sheet is 1mm. When the cover plate 160 is closed, the shoe washing machine 100 can work normally, while when the cover plate 160 is flipped up, the shoe washing machine 100 does not work and an alarm is triggered.

[0051] In some embodiments, a washing tank is also provided inside the main body box 140, and a plug is provided on the side of the main body box 140. The washing liquid can be poured into the washing tank by opening the plug. The design capacity of the washing tank can be between 0.2-0.5L. After the washing liquid is poured in, the washing liquid is pumped into the receiving cavity 121 by a peristaltic pump.

[0052] The shoe washing machine 100 provided in this embodiment of the invention has the following cleaning steps: First, the shoe body 200 to be cleaned is inserted into the rotating bracket 130 through the loading / unloading port 122, and the limiting rib is installed and used to limit the movement. Then, the cover plate 160 is placed on top for cleaning. During the actual cleaning process, a rough spray is first performed using the spray nozzle 153 for high-pressure rinsing to remove surface dirt and large particles of mud and sand. Then, the shoe body is drained once to remove the dirt. Next, the shoe body is soaked in water with detergent added. Once the water level covers the shoe body, drainage is stopped and ultrasonic washing is performed to remove stubborn deposits. After ultrasonic washing, a second drainage is performed to remove the dirt again. After draining, a fine spray is performed using the spray nozzle 153 for high-pressure rinsing to remove stubborn stains and detergent. Then, the shoe body is soaked in water again to rinse and remove detergent, followed by a third drainage. After draining, the shoe body is centrifuged and then dried with hot air while undergoing ozone sterilization. Finally, the shoe body is removed, completing the cleaning process.

[0053] In summary, the shoe washing machine 100 provided in this embodiment of the invention has a viewing cylinder 120 fixedly mounted on a base 110. The viewing cylinder 120 has an inner cavity 121, and the top of the inner cavity 121 is provided with a pick-up and drop-off port 122 for inserting and removing shoes 200 to be washed. A rotating bracket 130 is rotatably mounted on the base 110, located in the inner cavity 121, and capable of vertically placing at least two shoes 200 to be washed. A main body box 140 is compactly connected to the viewing cylinder 120 and mounted on the base 110. The main body box 140 is also provided with a spray assembly 150 for rinsing. The pick-up and drop-off port 122 is detachably provided with a cover plate 160. The viewing cylinder 120 forms an observation window for directly observing the shoes 200 to be washed. Compared to existing technologies, this invention avoids the use of a movable inner cleaning cylinder, employing a single-layer containment method and a vertical placement to accommodate multiple shoes 200 to be cleaned. Therefore, the volume of the visible cylinder 120 is reduced, resulting in a smaller overall shoe washing machine 100 with a simpler structure and smaller footprint. Furthermore, the visible cylinder 120 is equipped with an observation window, enabling visual monitoring of the cleaning process and direct observation of the shoe's cleaning status, which is very convenient. It also integrates automated rinsing, ultrasonic cleaning, drying, and sterilization functions, resulting in a higher level of intelligence.
