DETAILED DESCRIPTION

[0081] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0082] An intelligent shoe washing machine with high degree of freedom and precise cleaning, such as Figures 1 to 27 As shown, the box body 1 is provided with a microcontroller 3 and has at least one working chamber 200. The working chamber 200 has two working chambers 201, each working chamber 201 is used to place a shoe to be cleaned, and is provided with a movable telescopic spray device for extending into the shoe to be cleaned and a fixed rotating spray device located around the shoe to be cleaned. The movable telescopic spray device has a shoe-supporting spray component for spraying water and air into the inside of the shoe to be cleaned and sucking out the water inside the shoe to be cleaned, and the fixed rotating spray device has a rotating spray component 8 that can rotatably spray water and air to the outside of the shoe; the working chamber 200 is provided with an exhaust device 600 for discharging water vapor in the two working chambers 201 and a drain port 7 for discharging waste water after cleaning; the movable telescopic spray device, the fixed rotating spray device and the exhaust device 600 are all electrically connected to the microcontroller 3.

[0083] The spray assembly can spray water (for cleaning) and air (for drying). When spraying water, the mobile, retractable spray unit's shoe-stretching spray assembly, aided by a movable robotic arm, achieves precise cleaning. The fixed, rotating spray unit's rotary spray assembly, combined with the mobile, retractable spray unit's shoe-stretching spray assembly, provides comprehensive cleaning of the shoe's exterior. When airing, the spray assembly sprays dry, hot air, drying both the shoes being cleaned and the work chamber. Each working chamber has a sliding guide rail at the top, beneath which a foldable robotic arm houses a motor that allows it to extend and retract according to the type of shoe. The robotic arm is connected to the retractable shoe-stretching unit, and both contain water and air inlet pipes. The robotic arm controls the distance between the retractable shoe-stretching unit and the rotating spray assembly, providing a high degree of freedom.

[0084] More specifically:

[0085] like Figure 1 As shown, in this embodiment, the intelligent shoe washing machine 100 preferably adopts a box-type structure. The box 1 contains multiple working chambers 200 (three of which can be seen in the figure). Each working chamber 200 (with its two working chambers 201) can simultaneously clean a pair of shoes. The multiple working chambers 200 are controlled by a microcontroller 3. A control panel can also be provided on the box 1 to input control parameters to the microcontroller and / or display the shoe cleaning status. The microcontroller 3 can be an x86 architecture platform or a PLC controller platform, and includes the necessary components and equipment for normal operation.

[0086] like Figure 1 、 Figure 2 and Figure 3 As shown, in this embodiment, it is preferred that each working chamber 200 is provided with a chamber door 2. After the intelligent shoe washing machine 100 opens the chamber door 2, as shown in FIG. Figure 2As shown, the interior is a warehouse structure, and a vertical partition 4 is provided in the working chamber 200 to divide the space in the working chamber 200 into two side-by-side and relatively independent working chambers 201. A gap is provided between the top of the partition 4 and the top of the working chamber 200, and a vent 5 is formed between the two working chambers 201 for air circulation between the two working chambers 201. Figure 3 The two working chambers 201 in the same working chamber 200 have the same working environment (and the same working state), and the partition 4 can prevent a pair of shoes to be cleaned from interfering with each other during the cleaning process.

[0087] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 10 As shown, the preferred exhaust device 600 includes an exhaust port arranged on the working chamber 200, an exhaust grid 601 arranged at the exhaust port, an exhaust hood 602 arranged on the rear side of the exhaust grid 601, an exhaust hood exhaust port 603 arranged on the exhaust hood 602, an exhaust condensation ball 610 connected to the exhaust hood exhaust port 603, and an exhaust box 630 connected to the exhaust condensation ball 610.

[0088] like Figure 21 and Figure 22 As shown, further preferably, a temperature and humidity sensor 6031 for sensing temperature and humidity is provided on the inner wall of the exhaust hood outlet 603, and the temperature and humidity sensor 6031 is electrically connected to the microcontroller 3. An exhaust hood inner grille 604 is provided inside the exhaust hood 602, and the exhaust hood inner grille 604 is provided with an exhaust hood inner grille steam inlet 6040 and an exhaust hood inner grille steam outlet 6041. The exhaust hood inner grille 604 is connected to an exhaust hood inner grille servo 605 for driving its rotation, as shown in FIG. Figure 22 As shown, when the exhaust hood inner grille steam inlet 6040 is aligned with the exhaust grille 601, the exhaust hood inner grille steam outlet 6041 is aligned with the exhaust hood exhaust outlet 603, forming an exhaust passage. The exhaust hood inner grille servo 605 is electrically connected to and controlled by the microcontroller 3. During cleaning, the exhaust passage is closed; during drying, the exhaust passage is open.

[0089] like Figure 10 、 Figure 11 and Figure 19As shown, the exhaust condenser ball 610 preferably has a condenser ball body, and has an exhaust condenser ball steam inlet 611, an exhaust condenser ball liquid outlet 612, and an exhaust condenser ball exhaust outlet 613. The exhaust condenser ball steam inlet 611 is connected to the exhaust hood exhaust port 603, the exhaust condenser ball exhaust port 613 is connected to the exhaust box 630 through the first exhaust pipe 620, and the exhaust condenser ball liquid outlet 612 is connected to the first liquid outlet pipe 030. The function of the exhaust condenser ball 610 is to separate the gas and liquid in the exhaust steam, condense the water vapor, and discharge it in the form of condensed water. The condenser ball body is the main place for water vapor condensation, and the water vapor can be cooled by circulating cooling water or other cooling methods.

[0090] like Figure 19 and Figure 20 As shown, the exhaust box 630 is preferably provided with an exhaust fan 631, a drain port 633 disposed below the exhaust fan 631, and an exhaust box air inlet 632 and an exhaust grille 63 disposed on both sides of the exhaust fan 631.

The exhaust box 630 is preferably fixed to the inner wall of the intelligent shoe washing machine 100, and the exhaust grille 63 is disposed on the rear wall of the intelligent shoe washing machine 100. The exhaust box 630 discharges gas from the box through the exhaust grille 63.

[0091] like Figure 12 and Figure 13 As shown, the intelligent shoe washer also includes an image recognition sensor 2040 and a sterilization lighting mechanism, both located within each working chamber 201 and electrically connected to the microcontroller 3. The image recognition sensor 2040 is used to monitor, record, and identify shoes to be cleaned. The sterilization lighting mechanism comprises a sterilization lamp 2050 for sterilizing the working chamber 200 and the shoes to be cleaned, and an illumination lamp 2051 for illuminating the working chamber 200. Furthermore, the image recognition sensor 2040 is preferably provided with an image recognition sensor protective cover 204, and the sterilization lighting mechanism is provided with a sterilization lighting cover 205 to prevent moisture from damaging these devices. Furthermore, the image recognition sensor 2040 and the sterilization lighting mechanism are preferably located at the top of the working chamber 201.

[0092] Furthermore, users can preferably view the operating status of the shoe washer in real time via a mobile phone app, and monitor the conditions inside the working chamber 200 via the image recognition sensor 2040. The intelligent shoe washer 100 can be used in the sharing economy. The video recording function can fully record the shoe cleaning process, providing evidence in the event of a dispute involving shoe damage or damage. The image recognition sensor 2040 can identify the type of shoe and intelligently provide different cleaning modes. It can also identify the degree of dirtiness of the shoe and intelligently calculate a cleaning plan based on the degree of dirtiness, thereby achieving truly precise and intelligent cleaning. Identifying the shoe type and degree of dirtiness can be achieved using image recognition algorithms, such as those based on OpenCV visual processing algorithms.

[0093] like Figures 14-18 As shown, the preferred mobile telescopic spray device includes a telescopic shoe stretcher unit 2003 and a shoe stretcher moving unit. The shoe stretcher spray assembly is mounted on the telescopic shoe stretcher unit 2003. The shoe stretcher moving unit is disposed within a working chamber 201 and connected to the telescopic shoe stretcher unit to drive the telescopic shoe stretcher unit to move. Furthermore, the telescopic shoe stretcher unit preferably includes a shoe stretcher head 2010, a shoe stretcher middle 2020, and a shoe stretcher rear 2030, which are connected in sequence. The rear end of the shoe stretcher rear 2030 is provided with a push-button switch 2033 for controlling the opening and closing of the mobile telescopic spray device.

[0094] like Figure 14 、 Figure 15 and Figure 16 As shown, the shoe hanger moving unit includes a moving guide rail 2000 arranged at the top of the working chamber 201 (a first air inlet and exhaust pipe 01 is arranged in the moving guide rail 2000), a robotic arm base 2001 slidably connected to the moving guide rail 2000, a screw mechanism for driving the robotic arm base 2001 to slide on the moving guide rail 2000, and a two-link telescopic robotic arm 2002 connected to the bottom of the robotic arm base 2001. The screw mechanism and the two-link telescopic robotic arm 2002 are both moved by motor control, for example: the motor controls the screw mechanism to drive the robotic arm base 2001 to slide back and forth; the motor is set at the two joints of the two-link telescopic robotic arm 2002, and controls the two-link telescopic robotic arm 2002 to achieve bending of the robotic arm.

[0095] like Figure 14 and Figure 15 As shown, the rear portion 2030 of the shoe rack is preferably connected to a two-link retractable robotic arm 2002, and the positional relationship and distance between the shoes to be cleaned and the spray assembly are controlled by moving the guide rail 2000, the robotic arm base 2001, the two-link retractable robotic arm 2002, and the retractable shoe rack unit 2003.

[0096] like Figure 16 、 Figure 17 and Figure 18 As shown, the rear portion 2030 of the shoe tree preferably includes an inner wall positioning rod 2031 extending in the forward and backward direction. The middle portion 2020 of the shoe tree slides forward and backward on the inner wall positioning rod 2031. An adjustment spring 2032 is sleeved on the inner wall positioning rod 2031. The adjustment spring 2032 contacts a retaining ring 2023 on the middle portion 2020 of the shoe tree to adjust the position of the middle portion 220 on the rear portion 2030 of the shoe tree. Passive adjustment can be used. For example, in a default state, the adjustment spring 2032 is in an extended state. When a shoe is mounted on the telescopic shoe tree unit 2003, the shoe tree head 2010 contacts the inner wall of the shoe, squeezing it backward. The shoe tree head 2010 applies a backward force to the middle portion 2020, which in turn transmits the force to the adjustment spring 2032 via the retaining ring 2023. Alternatively, active adjustment can be used, for example, through active control via a rack and pinion structure and a drive motor. Preferably, the rear portion 2030 of the shoe support is provided with a limiting ring cover mounting portion 2034, such as Figure 9 As shown, it is used to install a limit cover 2035. The limit cover 2035 has a limit opening 2036. The limit opening 2036 is used to engage the limit ring 2023 on the middle portion 2020 of the shoe tree to prevent the middle portion 2020 from falling off the extendable rear portion 2030 of the shoe tree. The push-type switch 2033 on the rear end of the shoe tree rear portion 2030 is pressed when a shoe is installed, energizing the working circuit to perform functions such as cleaning, drying, and disinfecting the shoes. If a shoe falls off, the switch is released, the shoe washer stops working, and the user is notified of the abnormal state of the shoe washer through a warning sound, a warning light, and a mobile phone app.

[0097] like Figure 17 and Figure 18 As shown, the shoe tree's middle portion 2020 is primarily a hollow cylinder.
