Description

Technical Field

[0001] This utility model relates to the field of disinfection and drying equipment technology, and more specifically, to an intelligent disinfection and drying shoe box. Background Technology

[0002] Foot odor is caused by bacteria on the feet. Staphylococcus epidermidis, anaerobic bacteria, fungi, and Bacillus subtilis are known to be associated with foot odor. These bacteria decompose sebum and dead cells on the feet, much like decomposing rotten flesh, ultimately turning into ammonia, which produces the odor. This odor adheres to the user's shoes, especially athletic shoes and sneakers. During exercise, the increased sweating and higher internal temperature of the shoes create a warm, moist environment inside, causing the odor to linger and be difficult to dissipate. To address this technical problem, CN117861434A discloses a smart shoebox capable of decomposing and filtering exhaust gas, comprising a box body and a filtration mechanism; the filtration mechanism includes a sterilization component and a catalyst component; the sterilization component includes an ultraviolet lamp for sterilizing the exhaust gas; the catalyst component includes a cold catalyst for purifying the air; the box body forms a gas circulation zone for shoe cleaning and a gas desiccation zone for exhaust gas accumulation; the gas circulation zone is connected to an air inlet channel, and the gas desiccation zone is connected to the gas circulation zone and an air outlet channel; a fresh air inlet is connected to the air inlet channel, and an exhaust gas outlet is connected to the air outlet channel; the ultraviolet lamp is configured to be located within the gas desiccation zone to prevent it from irradiating the shoes placed in the gas circulation zone.

[0003] However, the above-mentioned solution has some unreasonable aspects in the way the gas flow inside the shoe box is driven. For example, the gas flow inside the shoe box is achieved by relying solely on the fan assembly at the air inlet channel inside the shoe body. This makes it difficult for the gas inside the shoe box to flow smoothly and quickly from the air outlet. In addition, in the existing solution, the distance between the air inlet and the air outlet is too close, which can easily cause the fresh air intake and exhaust gas to mix, resulting in the exhaust gas repeatedly entering the shoe box. Utility Model Content

[0004] The purpose of this application is to provide an intelligent disinfection and drying shoe box and its control method, which has the advantages of improving air outlet efficiency, avoiding the mixing of fresh air and exhaust gas, and ensuring that plasma and hot air evenly cover the inside of the shoe to improve the disinfection and drying effect.

[0005] This application provides an intelligent disinfection and drying shoe box, the technical solution of which is as follows: An intelligent disinfection and drying shoe box includes an openable and closable box body suitable for placing shoes and a top cover assembly disposed on the top of the box body. The top cover assembly forms an air inlet channel and an air outlet channel communicating with the box body. The box body is characterized by further including: a plasma generator and a drying fan connected to the air inlet channel. The air inlet channel includes a first air outlet and a second air outlet corresponding to the shoe openings of two shoes placed inside the box body. The drying fan blows the plasma generated by the plasma generator into the inside of the shoes to dry and disinfect them. The air outlet channel includes a connecting section connecting to the box body and an exhaust section. An ultraviolet irradiation component is disposed at the connecting section, and a filter component is disposed in the exhaust section to filter the exhaust gas. An exhaust fan is disposed at the end of the exhaust section to allow the exhaust gas to be quickly discharged from the box body, and the exhaust efficiency of the exhaust fan is lower than the air delivery efficiency of the drying fan.

[0006] Furthermore, this application also proposes that a heating wire is provided in the air inlet channel, the heating wire is located downstream of the drying fan along the air supply path, and the plasma generator is located downstream of the heating wire and close to the first air outlet and the second air outlet.

[0007] Furthermore, this application also proposes that the top cover assembly includes a fresh air inlet connected to the air inlet channel and an exhaust gas outlet connected to the air outlet channel, with the fresh air inlet and the exhaust gas outlet located at the left and right ends of the same side of the top cover assembly to prevent cross-contamination of air.

[0008] Furthermore, this application also proposes that a control board is provided inside the upper cover assembly, and the control board is connected to the air intake path of the air intake channel and the fresh air intake.

[0009] Furthermore, this application also proposes that the upper cover assembly includes an upper cover plate and a lower cover plate, with an installation chamber formed between the upper cover plate and the lower cover plate. An air inlet channel, an air outlet channel, and a control panel are disposed in the installation chamber, and the fresh air inlet and the exhaust gas outlet are disposed on one side of the installation chamber.

[0010] Furthermore, this application also proposes that a concave exhaust groove with a connecting section is formed on the lower cover plate, and the ultraviolet irradiation component is disposed at the downstream end of the exhaust groove; the first air outlet and the second air outlet are disposed on the lower cover plate and at a position away from the exhaust groove.

[0011] Furthermore, this application also proposes that the upper end of the exhaust duct is provided with a temperature detection device and a humidity detection device connected to the control board for detecting the temperature and humidity of the exhaust gas discharged from the box.

[0012] Furthermore, this application also proposes that the temperature inside the box is suitable for controlling the heat output of the heating wire through a control board to maintain a constant temperature range of 45-50°C.

[0013] Furthermore, this application also proposes that the top cover assembly is equipped with a display control screen for controlling the operation of the intelligent disinfection and drying shoe box.

[0014] Furthermore, this application also proposes that the filter assembly includes a cold catalyst filter block for filtering exhaust gas.

[0015] As can be seen from the above, the intelligent disinfection and drying shoe box provided in this application, by setting up dual air outlets for the air inlet channel corresponding to the shoe openings of the two shoes respectively, combined with the synergistic effect of the drying fan and the exhaust fan, achieves uniform coverage of the inside of the shoe with plasma and hot air, while avoiding the mixing of fresh air and exhaust gas, and has the advantages of improving air outlet efficiency and ensuring consistent disinfection and drying effects.

Detailed Implementation

[0026] Combination Figures 1 to 9 As shown, this embodiment provides an intelligent disinfection and drying shoe box, including an openable and closable box body 1 and a top cover assembly 2. The top cover assembly 2 is provided with an air inlet channel 3 and an air outlet channel 4. The air inlet channel 3 is connected to a plasma generator and a drying fan 33, and has two air outlets corresponding to the shoe openings. The air outlet channel 4 includes a connecting section 42 with an ultraviolet irradiation component 6 and an exhaust section 43 with a filter component. An exhaust fan 45 is provided at the end. The exhaust efficiency of the exhaust fan 45 is lower than the air delivery efficiency of the drying fan 33.

[0027] The plasma generator is a device that generates positive and negative ions through high-voltage discharge. Specifically, it can be implemented using a needle-shaped electrode array connected to a high-voltage transformer, generating positive and negative ions with sterilization functions by ionizing air. The drying fan 33 is a centrifugal fan with directional airflow function, specifically driven by a brushless DC motor, used to establish a positive pressure environment in the air inlet channel 3. Exhaust efficiency control refers to adjusting the motor speed to ensure the exhaust airflow is less than the intake airflow, specifically implemented using a PWM speed control module, used to maintain the pressure difference between the inside and outside of the housing 1. The ultraviolet irradiation component 6 is a sterilization device that emits ultraviolet light of a specific wavelength, used for secondary sterilization of the flowing exhaust gas. The filter component is a purification module with adsorption and decomposition functions, specifically using honeycomb cold catalyst filter blocks, used to remove odor molecules from the exhaust gas.

[0028] Specifically, when the equipment is running, the drying fan 33 drives outside air into the air inlet channel 3. After being heated, the air, carrying plasma, is injected into the shoe body through two directional air outlets. After the plasma completes sterilization and deodorization inside the shoe cavity, the exhaust gas carrying odor molecules undergoes secondary ultraviolet treatment at the connecting section 42, and is then purified by a cold catalyst filter before being discharged. The exhaust fan 45 operates at low power to ensure a positive pressure state inside the box 1, preventing untreated gas from flowing back. This pressure difference causes the gas to form a unidirectional flow path. After fresh air enters from the directional air outlets, it pushes the exhaust gas out along a preset path, effectively preventing airflow mixing.

[0029] This solution establishes forced convection through dual-fan differential pressure control. Traditional UV lamps are fixed in the de-icing zone; this solution integrates the UV components into the flow path for dynamic sterilization. Existing inlet and outlet layouts are prone to airflow short-circuiting; this solution guides gas flow in a directional manner through pressure gradients, combined with physical isolation design to block mixing channels.

[0030] Through the above technical solutions, this application achieves efficient gas replacement within the shoe cavity, ensuring that the disinfection medium fully contacts the inside of the shoe. The exhaust gas treatment system eliminates the risk of odor leakage through multi-stage purification, and the pressure control system effectively prevents the mixing of fresh air and exhaust gas. The directional air supply structure improves plasma utilization, and the dynamic sterilization process enhances the treatment effect on flowing exhaust gas.

[0031] Combination Figures 1 to 4 As shown, in this embodiment, the box 1 is equipped with an opening and closing door or a pull-out door to facilitate the insertion and removal of the shoes. When closed, the box 1 forms a relatively sealed space, allowing gas to enter only through the air inlet channel 3 and exit through the air outlet channel 4, preventing gas from escaping from other locations. An upper cover assembly 2 is provided above the box 1. The upper cover assembly 2 includes an upper cover plate 21 and a lower cover plate 22, forming an installation chamber 23 between the upper cover plate 21 and the lower cover plate 22. The air inlet channel 3, the air outlet channel 4, and the control panel 5 are disposed within the installation chamber 23, and the fresh air inlet 36 and the exhaust gas outlet 44 are located on one side of the installation chamber 23. Here, the space between the installation chamber 23 and the box 1 is separated by the lower cover plate 22.

[0032] The installation chamber 23 refers to the enclosed space formed by the upper cover plate 21 and the lower cover plate 22, which is used to centrally accommodate the air inlet channel 3, the air outlet channel 4, the control panel 5, and other components. The fact that the fresh air inlet 36 and the exhaust gas outlet 44 are located on the same side of the installation chamber 23 means that they are located in the same edge area of ​​the cover plate assembly, physically separated by left-right spacing. Preferably, the fresh air inlet 36 and the exhaust gas outlet 44 are located at the left and right ends of the same side of the upper cover assembly 2 to prevent cross-contamination of airflow.

[0033] Specifically, the air inlet channel 3 and the air outlet channel 4 are integrated inside the mounting chamber 23, forming independent airflow channels to avoid interference from the external environment. The control board 5 is fixed in the airflow path area within the mounting chamber 23, for example, by screws to a protrusion on the inner wall of the cover plate, and is connected to the heating wire 31 and fan of the air inlet channel 3 via wires. The fresh air inlet 36 is located on the left edge of the lower cover plate 22, and the exhaust outlet 44 is located on the right edge of the same side, with a distance of 10-15 cm between them, forming a physical isolation between the air inlet and exhaust outlets. The airtight connection between the cover plates is achieved inside the mounting chamber 23 through sealing strips to prevent airflow leakage.

[0034] This design places both air intake and exhaust air on the same side but separately on the left and right, shortening the duct length and preventing gas mixing through spatial isolation. This achieves physical isolation between the intake and exhaust airflows, allowing fresh air to enter from the left, be heated and treated with plasma, and then be vertically delivered downwards to the shoe body, while exhaust air exits from the right after undergoing ultraviolet disinfection. The two airflow paths do not intersect within the chamber. The structural design of the mounting chamber 23 allows the control board 5 and the duct components to form a modular assembly unit, facilitating overall disassembly and maintenance.

[0035] In this embodiment, the fresh air inlet 36 refers to the channel opening for introducing external air, which can be implemented using a rectangular opening structure with a dustproof mesh. It is connected to the air inlet channel 3 to introduce untreated gas. The exhaust gas outlet 44 refers to the channel opening for discharging treated gas, which can be implemented using a circular opening structure with a baffle plate. It is connected to the air outlet channel 4 to discharge filtered and disinfected gas. The fresh air inlet 36 and the exhaust gas outlet 44 are located at opposite ends on the same side of the upper cover assembly 2. Because they are on the same side but located at opposite ends, the fresh air and exhaust gas will not cross or mix during flow, thereby avoiding the backflow of treated gas or contamination of untreated gas.

[0036] Compared to existing technologies, the current solutions have excessively close proximity between the fresh air inlet and the exhaust outlet, leading to overlapping airflow paths and the potential re-entry of some exhaust gas into the recirculation area. This application addresses this by placing the air inlet and outlet on the same side, maintaining the structural compactness of the top cover assembly 2 while utilizing spatial separation to prevent airflow intersections, ensuring complete separation of fresh air and exhaust gas in the flow direction. This effectively prevents the mixing of external air and treated exhaust gas during flow, avoiding secondary pollution caused by exhaust gas re-entering the shoe box. Simultaneously, this layout optimizes the independence of the airflow path, improves gas circulation efficiency, and ensures that the inside of the shoe remains clean and dry at all times.

[0037] Combination Figure 8 As shown, in this embodiment, a heating wire 31 is provided in the air inlet channel 3. The heating wire 31 is located downstream of the drying fan 33 along the air supply path. The plasma generator is located downstream of the heating wire 31 and close to the first air outlet 34 and the second air outlet 35.

[0038] The heating wire 31 is a resistance wire element used to heat the flowing air. It can be made of nickel-chromium alloy wound into a spiral structure and positioned behind the drying fan 33 along the airflow path, allowing the airflow to be pressurized by the fan before being heated. The plasma generator is a component that generates positive and negative ions through high-voltage discharge. It can be implemented using a discharge module composed of needle-shaped electrodes connected to a high-voltage transformer. Positioned behind the heating wire 31, it allows hot air carrying plasma to directly act on the inside of the shoe. This also prevents the generated positive and negative ions from being adsorbed by the heating wire 31, reducing ion loss.

[0039] Specifically, when the drying fan 33 operates, it pushes air through the heating wire 31 to form hot air, which then enters the plasma generator and mixes with ionized gas. Because the plasma generator is close to the air outlet, the airflow carrying heat and active particles can quickly enter the interior space of the shoe. The heating wire 31 is located downstream of the fan, avoiding the impact of high temperatures on the motor. Simultaneously, the temperature gradient decreases as the hot air flows through the plasma region, which helps maintain stable plasma generation. Through this arrangement, the heated, humid air comes into full contact with the plasma, accelerating the evaporation of moisture inside the shoe and enhancing the inactivation of microorganisms. The positive and negative ions generated by the plasma generator 32 can disinfect harmful gases such as bacteria and viruses in the air, while also initiating oxidation-reduction reactions against odor-causing substances.

[0040] Compared to existing technologies, current solutions do not optimize the order of the heating and plasma components, resulting in low heat exchange efficiency and uneven plasma distribution. This application adjusts the positional relationship between the heating wire 31 and the plasma generator, allowing the hot air to complete the heating process before ionization, thus avoiding the dilution of plasma concentration by the low-temperature airflow. Simultaneously, it shortens the plasma action path, reducing the natural attenuation of active particles during transport. This achieves rapid drying and efficient disinfection of the humid air inside the shoe, effectively preventing the mixing of fresh air and exhaust gas along the flow path. The synergistic effect of hot air and plasma improves the temperature control accuracy of the shoe's internal environment, and the active particles directly act on the microbial aggregation area, solving the problems of low drying efficiency and incomplete disinfection caused by unreasonable airflow organization in traditional solutions.

[0041] Combination Figures 2 to 4 As shown, in this embodiment, a control board 5 is provided inside the upper cover assembly 2, and the control board 5 is connected to the air intake path between the air intake channel 3 and the fresh air intake 36.

[0042] The control board 5 refers to the electronic control unit used to control the operation of the system, which can be a microcontroller or a PCBA board, and can adjust the wind speed, temperature, opening and closing, etc. The air inlet path refers to the flow trajectory of fresh air entering the air inlet channel 3 from the outside. The air outlet channel 4 is equipped with an independent housing structure to isolate it from the air inlet channel 3. In one embodiment, the control board 5 can be located on the air inlet path, allowing the airflow to dissipate heat from the control board 5. Since a filter screen is provided at the fresh air inlet 36, dust can be prevented from affecting the PCBA board. Preferably, a protective housing can also be provided on the PCBA board, which also serves the functions of heat dissipation and protection.

[0043] Specifically, the control board 5 is integrated at the upstream end of the air inlet channel 3. When the fresh air enters the air inlet channel 3, it flows over the surface of the control board 5, carrying away the heat generated during its operation. The filter plate at the fresh air inlet 36 adopts a detachable honeycomb structure, which blocks dust while maintaining unobstructed airflow. When the drying fan 33 is started, fresh air is directed to the inside of the shoe body along a preset path, while exhaust gas is discharged through an independent air outlet channel 4, forming a unidirectional circulation between the two airflows.

[0044] This solution physically separates the air intake and exhaust paths, completely isolating fresh air from polluted exhaust fumes. Simultaneously, the integration of the control board 5 with the fresh air path enables self-heating of the equipment, preventing performance degradation of electronic components due to high temperatures. The filter further ensures the cleanliness of the air entering the shoebox, preventing secondary pollution.

[0045] Combination Figures 6 to 7 As shown, in this embodiment, a concave exhaust groove 41 with a connecting section 42 is formed on the lower cover plate 22, the ultraviolet irradiation component 6 is disposed at the downstream end of the exhaust groove 41, and the first air outlet 34 and the second air outlet 35 are disposed on the lower cover plate 22 and away from the exhaust groove 41.

[0046] The concave exhaust channel 41 refers to a flow channel with a downwardly recessed structure. Specifically, this can be achieved by injection molding an arc-shaped groove on the surface of the plastic lower cover plate 22. This structure guides the exhaust gas along the channel, preventing diffusion. The ultraviolet irradiation component 6 is located at the downstream end of the exhaust channel 41, meaning that the ultraviolet lamp or LED bead is installed at the end of the channel. It can be connected to the end of the exhaust channel 41 by clips or adhesive, ensuring that the exhaust gas flows through the ultraviolet irradiation area before being discharged, without directly irradiating the shoe body. The first air outlet 34 and the second air outlet 35 are located away from the exhaust channel 41, meaning that the two air outlets are distributed on the opposite side or diagonally opposite side of the lower cover plate 22 where the exhaust channel 41 is located. Specifically, the mold design can maintain a distance of at least 15 cm between the air outlets and the exhaust channel 41, thus avoiding intersection of the air intake and exhaust paths. The ultraviolet irradiation component 6 can also use a front-mounted ultraviolet lamp (UVC) in the 200nm-280nm band. The function of the front-mounted ultraviolet lamp is to perform secondary sterilization and odor decomposition on the exhaust gas. Preferably, ultraviolet light in the 254nm-270nm band is most effective for ozone decomposition, ensuring that ozone does not escape from the outside of the device.

[0047] Specifically, the arc-shaped inner wall of the concave exhaust channel 41 can constrain the flow direction of the exhaust gas, concentrating it into the connecting section 42 and preventing it from dissipating in all directions. The ultraviolet irradiation component 6 covers the entire cross-section of the channel in the working area at the end of the exhaust channel 41, ensuring that all the exhaust gas flowing through it receives ultraviolet radiation for sterilization. The first air outlet 34 and the second air outlet 35 are located on the side of the lower cover plate 22 away from the exhaust channel 41, allowing fresh air to enter from one side of the shoe box and blow directly into the inside of the shoe, while the exhaust gas is discharged from the other side, forming a unidirectional flow path. This layout completely isolates the fresh air and exhaust gas in space, avoiding airflow mixing that would reduce disinfection efficiency.

[0048] Compared to existing technologies, the air outlet duct 4 of current shoe boxes relies solely on a single fan to drive airflow, and the close proximity of the air inlet and outlet causes airflow short-circuiting. This solution constructs a directional airflow channel through a concave exhaust groove 41, combined with the terminal layout of the ultraviolet component, ensuring thorough disinfection of the exhaust gas before it is discharged. Simultaneously, the distance between the air inlet and the exhaust groove 41 creates spatial isolation, eliminating the crossover of fresh air and exhaust gas in their flow paths.

[0049] Through the above technical solution, this application can effectively prevent the mixing and crossflow of fresh air and exhaust gas inside the shoe box, ensuring that the disinfected exhaust gas is fully treated with ultraviolet sterilization before being discharged. The guiding function of the concave exhaust groove 41, combined with the partitioned layout of the air supply and exhaust vents, forms a unidirectional and efficient airflow circulation path, which allows the humid air inside the shoe to be quickly replaced, while avoiding direct ultraviolet radiation to the shoe body, which can cause material aging.

[0050] Combination Figure 4As shown, in this embodiment, a temperature detection device 9 and a humidity detection device connected to the control board 5 are arranged at the upper end of the exhaust trough 41 to detect the temperature and humidity of the exhaust gas discharged from the box 1.

[0051] The temperature detection device 9 is a sensor used to measure changes in exhaust gas temperature. It can be implemented using a thermistor or thermocouple and is installed upstream of the airflow path in the exhaust duct 41 to capture exhaust gas temperature data undisturbed by the external environment. The humidity detection device is a sensor used to measure exhaust gas humidity parameters. It can be implemented using a capacitive or resistive humidity sensor and is installed alongside the temperature detection device 9 in the same area of ​​the exhaust duct 41 to synchronously acquire exhaust gas humidity information. The upper orientation of the exhaust duct 41 refers to the opening direction at the connection between the exhaust duct 41 and the housing 1. It can be designed as a vertically upward or inclined upward structure to create a stable airflow path for the exhaust gas entering the exhaust duct 41, preventing the detection devices from being obstructed by foreign objects.

[0052] Specifically, when exhaust gas enters the exhaust duct 41 from the housing 1, the temperature detection device 9 and the humidity detection device simultaneously collect the temperature and humidity data of the exhaust gas and transmit the data to the control board 5 in real time. The control board 5 determines whether there is a risk of overheating inside the housing 1 based on the received temperature data. For example, if the temperature exceeds a preset threshold, it automatically reduces the power of the heating wire 31. Simultaneously, it monitors the dryness of the shoe body through humidity data. When the humidity drops to a set range, the control board 5 can adjust the speed of the exhaust fan 45 or stop the drying process. Because the detection device is located upstream of the exhaust duct 41, it can accurately reflect the state of the exhaust gas about to be discharged, avoiding control errors caused by detection delays.

[0053] Compared to existing technologies, current solutions lack exhaust gas status monitoring devices and rely solely on fixed wind speeds or timed airflow control, making it impossible to dynamically adjust equipment operation based on actual drying needs. This application, however, monitors exhaust gas temperature and humidity in real time, enabling the control board 5 to accurately determine the shoe drying progress, avoiding energy waste from over-drying. Temperature feedback also prevents excessive heat inside the box 1 from damaging the shoe material. Furthermore, existing technologies typically place the detection device inside the box 1, which is easily affected by shoe obstruction or moisture condensation, impacting measurement accuracy. This application moves the detection point to the upstream end of the exhaust channel 41, avoiding direct contact with the shoe while ensuring the data reflects the true exhaust gas status. This solves the problem of exhaust gas stagnation caused by low gas flow efficiency in the exhaust channel 4. By dynamically adjusting the exhaust fan 45 speed through real-time monitoring of the exhaust gas status, the exhaust gas discharge speed matches the drying progress. Simultaneously, detecting exhaust gas humidity determines the shoe's dryness, preventing secondary pollution caused by mixing fresh air with incompletely dried exhaust gas. In addition, the coordinated operation of the temperature detection device 9 and the humidity detection device enables closed-loop control of temperature and humidity inside the box 1, ensuring a safe and efficient drying process.

[0054] During operation, the temperature inside the chamber 1 is controlled by the control board 5 to maintain a constant temperature range of 45-50℃ by controlling the heat output of the heating wire 31. After the shoes have finished drying, deodorizing, and sterilizing, and after the shoes are removed, the entire device can be set to work continuously for 5-30 minutes to thoroughly remove and decompose residual gases and odors remaining in the chamber, filter, and air duct, ensuring the cleanliness of the device before the next operation.

[0055] The control board 5 can be implemented using a microcontroller with a PID algorithm. It dynamically adjusts the working state of the heating wire 31 by acquiring the detection data from the temperature sensor in real time and outputting the corresponding pulse width modulation signal. The constant temperature range refers to the stable temperature range maintained by closed-loop control. Specifically, it can be achieved by setting the temperature threshold and hysteresis control parameters. This temperature range can ensure the thermal environment required for plasma disinfection while avoiding thermal deformation of common shoe materials.

[0056] Specifically, the control board 5 continuously monitors the temperature inside the housing 1 using a temperature sensor. When the detected temperature is below 45°C, the control board 5 increases the power output of the heating wire 31 to raise the airflow temperature; when the temperature exceeds 50°C, it reduces the heating power or stops supplying power. This adjustment process forms a closed-loop control through a real-time feedback mechanism, limiting temperature fluctuations within a preset range. A plasma generator located downstream of the heating wire 31 can continuously generate highly active ions in a stable temperature environment of 45-50°C. This temperature range is below the softening critical temperature of synthetic leather, fabrics, and other shoe materials, preventing high temperatures from causing the shoe to delaminate or deform.

[0057] This solution uses closed-loop feedback control and constant temperature range setting to keep temperature fluctuations within ±2.5℃. While ensuring the efficiency of microbial inactivation, it avoids heat damage to materials, solving the problem of insufficient disinfection effect or high temperature damage to shoe materials caused by unstable internal temperature control of shoe boxes. Through precise constant temperature control, the inside of the shoe body is maintained in the optimal temperature range for effective disinfection without damaging the materials, ensuring the safety and consistent treatment effect of different shoe materials such as sports shoes and leather shoes during the drying and disinfection process.

[0058] Combination Figures 1 to 2 As shown, in this embodiment, a display control screen 8 is also provided on the upper cover assembly 2 for controlling the operation of the intelligent disinfection and drying shoe box.

[0059] Among them, the display control screen 8 refers to an interactive interface that integrates touch and display functions. Specifically, it can be implemented using a capacitive touch screen combined with an LCD screen, with its surface covered with an anti-fogging treatment layer to adapt to the humidity environment inside the shoe box. This feature integrates the operation interface and status display on the same plane, enabling users to monitor and adjust the device's operating parameters in real time.

[0060] Specifically, the display control screen 8 and the circuit control module of the upper cover assembly 2 are connected via a flexible ribbon cable. The screen automatically activates to display the current operating mode when the shoebox is started. When the user selects the drying temperature setting via touch, the control signal is transmitted to the heating wire 31 drive circuit via the internal bus, simultaneously displaying the difference between the set value and the actual temperature on the screen in digital form. During the sterilization program, the working status of the ultraviolet component is dynamically displayed via icons. When the filter component needs to be replaced, a prompt message pops up on the screen accompanied by a buzzer reminder.

[0061] In some specific embodiments, the display control screen 8 can be installed at the front edge of the upper cover assembly 2, with its tilt angle set at 15-30 degrees to the horizontal plane to optimize the viewing angle. The screen surface is treated with a hydrophobic coating to prevent condensation droplets from affecting touch sensitivity. By integrating the display control screen 8, parameter settings, mode switching, and fault alarm functions are centralized in a single interactive interface, eliminating redundant steps that require users to repeatedly confirm button functions during operation.

[0062] In this embodiment, the filtration assembly includes a cold catalyst filter block 7 for filtering exhaust gas.

[0063] Among them, the cold catalyst filter block 7 refers to a porous material structure that decomposes organic pollutants in exhaust gas through catalytic oxidation reaction under normal temperature conditions. Specifically, it can be realized by using a honeycomb ceramic carrier loaded with nano-titanium dioxide and noble metal catalysts. Its surface has a high specific area and active sites to promote the oxidative decomposition of ammonia and sulfides.

[0064] Specifically, when exhaust gas containing bacterial metabolites passes through the cold catalyst filter block 7, the catalyst promotes the reaction of ammonia and oxygen to produce nitrogen and water, while simultaneously decomposing volatile organic compounds into carbon dioxide and water. Since the cold catalyst maintains its catalytic activity at room temperature, no additional heating device is required, avoiding the energy consumption required by traditional high-temperature catalysis. The chemical stability of the cold catalyst ensures that it will not become ineffective due to adsorption saturation during long-term use, continuously purifying the exhaust gas emitted from the shoebox and thus blocking the diffusion paths of odorous substances and microorganisms. This solution, through the catalytic decomposition mechanism of the cold catalyst, converts odorous substances into harmless substances at room temperature, avoiding the problem of high replacement frequency of adsorption materials and achieving complete elimination of organic pollutants. It effectively solves the problem of secondary pollution caused by residual odorous substances such as ammonia in the exhaust gas, converting harmful components into harmless products through catalytic oxidation reactions, while reducing the maintenance requirements of the filter components and improving the sustainable operation capability of the shoebox exhaust gas purification system.
