Description

Technical Field

[0001] This utility model relates to the field of disinfection equipment technology, and in particular to a disinfection shoe and bag cabinet that can collect ozone. Background Technology

[0002] As people's living standards improve, the hygiene and disinfection of personal items such as shoes and bags are receiving increasing attention. Currently, shoe disinfection cabinets with ultraviolet (UV) or ozone functions are available on the market. Their basic principle is to install UV lamps inside the cabinet. While using UV light to kill bacteria, specific wavelengths of UV light excite oxygen in the air to produce ozone. The strong oxidizing properties of ozone further kill bacteria and fungi, and remove odors. These shoe and bag disinfection cabinets are typically designed for home use and are often placed in indoor spaces such as entryways, dressing rooms, and bedrooms. They require high standards in terms of equipment size, ease of use, and waste disposal methods.

[0003] However, existing shoe disinfection cabinets generally suffer from a technical flaw: residual ozone inside the cabinet cannot be effectively treated after disinfection. Most products use natural decomposition or built-in activated carbon filtration. Natural decomposition takes a long time, and users may still smell an irritating odor when opening the door; activated carbon filtration suffers from adsorption saturation and requires regular filter replacement. For the aforementioned small household devices, limitations in installation environment, size, and cost generally make it unsuitable to install external exhaust ducts, large ozone decomposition modules, or complex gas delivery mechanisms; if residual ozone is directly emitted into the room, it may cause irritating odors and affect the user experience. Therefore, how to collect and subsequently treat residual ozone inside the cabinet after disinfection while maintaining a simple device structure and ease of home use has become a problem that needs to be solved. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a disinfection shoe and bag cabinet that can collect ozone, so as to solve the problem that residual ozone in existing small household disinfection shoe cabinets is difficult to handle conveniently.

[0005] Based on the above objectives, this utility model provides a disinfection shoe and bag cabinet that can collect ozone, including a cabinet body. The inner side of the cabinet body is provided with several ultraviolet lamps for disinfecting the inside of the cabinet body and generating ozone. One side of the cabinet body is open, and a cabinet door is provided at the open. A sealing strip is provided on the edge of the cabinet door facing the open. When the cabinet door is closed, the sealing strip abuts against the edge of the open. A shelf is slidably connected inside the cabinet body, and an air duct is opened inside the cabinet body near the bottom. An ozone collection bag is detachably installed on the outside of the cabinet. The inside of the cabinet is connected to the ozone collection bag through the air passage, which is equipped with a check valve. A piston airbag is installed on the top inner side of the cabinet. A miniature fan is installed on the top of the cabinet to fill the piston airbag with outside air. When the piston airbag is inflated, the ozone-containing gas inside the cabinet can be squeezed and enter the ozone collection bag through the air passage.

[0006] According to the technical solution provided in this application, the check valve includes a base, a valve body, a ball, and a spring. The base is detachably installed at the bottom of the cabinet. The valve body is fixedly installed on the base and connected in series in the air passage. The valve body is cylindrical, and both ends of the valve body form tapered ends with reduced inner diameters. The ball is slidably installed in the valve body. One end of the spring is connected to one end of the valve body, and the other end is connected to the ball, so that the ball abuts against the corresponding tapered end and seals the valve body in its natural state.

[0007] According to the technical solution provided in this application example, the shelf is provided with several hollowed-out holes; the shelf is provided with a handle on the side edge near the cabinet door for pulling out.

[0008] According to the technical solution provided in this application example, the piston airbag includes an upper square corrugated tube and a thin film disposed at the lower end of the square corrugated tube. The upper end of the square corrugated tube is fixedly disposed on the inner top surface of the cabinet.

[0009] According to the technical solution provided in this application example, the end of the airway is connected in series with an air outlet pipe, an air inlet is provided on one side of the ozone collection bag, the air inlet is detachably connected to the air outlet pipe, and an annular sealing ring is provided on the outer periphery of the connection between the air inlet and the air outlet pipe; a sealing cap is detachably provided on the air outlet pipe.

[0010] According to the technical solution provided in this application example, an exhaust pipe is provided on the outside of the cabinet, and an air outlet is provided on one side of the ozone collection bag. The air outlet is detachably connected to the exhaust pipe, and an annular sealing ring is provided around the connection between the air outlet and the exhaust pipe. A miniature fan is provided at the end of the exhaust pipe for actively discharging ozone-containing gas from the ozone collection bag.

[0011] According to the technical solution provided in this application example, a one-way air valve is connected in series on the exhaust pipe. The one-way air valve is located between the air outlet and the micro fan II. The air outlet end of the micro fan II is provided with a cover.

[0012] The beneficial effects of this utility model are as follows: This ozone-collecting disinfection shoe and bag cabinet, after disinfection and ozone generation via ultraviolet lamps, uses a piston airbag to compress the internal space of the cabinet, transferring the residual ozone-containing gas inside to a detachable ozone collection bag. This achieves centralized collection of residual ozone, reducing the possibility of ozone remaining inside the cabinet for extended periods or directly escaping into the room when the door is opened, thus lowering odor residue and health risks. Simultaneously, the ozone collection bag can be removed independently, allowing users to easily take the collected ozone outdoors for disposal. Alternatively, a miniature fan combined with a one-way valve can slowly discharge the ozone at a low flow rate, reducing the possibility of excessively high local concentrations due to a single release of ozone. This improves the convenience and flexibility of using this small household disinfection shoe and bag cabinet for handling residual ozone. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] like Figures 1-6 As shown, this utility model provides a disinfection cabinet for shoes and bags that can collect ozone, including a cabinet body 100. Several ultraviolet lamps 101 are installed on the inner side of the cabinet body 100 (e.g., the inner surfaces of the back panel and left and right side panels). The ultraviolet lamps 101 emit 253.7nm wavelength ultraviolet light to directly kill bacteria inside the cabinet. Additionally, some of the ultraviolet light (especially in the 185nm band) can convert oxygen in the air inside the cabinet body 100 into ozone, achieving synergistic disinfection. One side of the cabinet body 100 is open, and a cabinet door 110 is connected to the open side via a hinge. A sealing strip 111 is installed on the edge of the cabinet door 110 facing the open side. When the cabinet door 110 is closed, the sealing strip 111 abuts against the edge of the open side of the cabinet body 100, so that the cabinet door 110 and the cabinet body 100 form a relatively sealed disinfection space. A shelf 120 is slidably connected inside the cabinet 100 for storing shoes, bags, and other items. To achieve this sliding connection, guide grooves are provided between the two side edges of the shelf 120 and the inner sidewall of the cabinet 100, allowing the shelf 120 to slide relative to the cabinet 100 in the front-back direction for easy access by the user. An air duct 103 is provided inside the cabinet 100 near the bottom. Preferably, a groove 102 is also provided on the bottom surface, with the air duct 103 located in the center of the groove 102. The groove 102 serves to collect and guide airflow, facilitating the natural collection of ozone-containing gas into the air duct.

[0019] Furthermore, an ozone collection bag 200 (e.g., an airtight bag made of plastic composite film) is detachably installed on the outside of the cabinet 100. The inside of the cabinet 100 is connected to the ozone collection bag 200 via an air duct 103, and a check valve 210 is installed on the air duct 103. A piston airbag 220 is installed on the inner top surface of the cabinet 100, and a miniature fan 130 is installed on the outer side of the top of the cabinet 100 or in the internal cavity. The air outlet of the miniature fan 130 is connected to the inside of the piston airbag 220 via a pipe. When the miniature fan 130 is activated, it fills the piston airbag 220 with outside air, causing the piston airbag 220 to expand and increase in volume, thereby compressing the ozone-containing gas originally inside the cabinet 100, forcing the gas to enter the ozone collection bag 200 through the air duct 103 and the check valve 210. In this way, after disinfection, the ozone remaining in the cabinet is physically transferred to the external collection bag, and the check valve 210 can prevent the gas in the ozone collection bag 200 from flowing back into the cabinet 100.

[0020] Preferably, the miniature fan 130 is a reversible miniature fan. When the miniature fan 130 rotates forward, it fills the piston airbag 220 with outside air, causing it to expand and squeeze the ozone-containing gas inside the cabinet 100 into the ozone collection bag 200. When it is necessary to take or put away items, the miniature fan 130 rotates in reverse, drawing out the air from inside the piston airbag 220. Under the action of negative pressure, the square corrugated tube 221 and the membrane 222 actively contract and return to their original position, thereby creating sufficient operating space above the shelf 120.

[0021] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, the air passage 103 is located inside the bottom of the cabinet 100, and a check valve 210 is provided in the middle of the air passage 103. The check valve 210 includes a base 211, a valve body 212, a ball 213, and a spring 214. The base 211 is detachably installed at the bottom of the cabinet 100, and the valve body 212 is fixedly installed on the base 211 and connected in series in the air passage 103. The valve body 212 is cylindrical, and both ends of the valve body 212 form tapered ends with a reduced inner diameter; the ball 213 is slidably disposed inside the valve body 212, and one end of the spring 214 is connected to one end of the valve body 212, and the other end is connected to the ball 213. In its natural state, the spring 214 pushes the ball 213 against the corresponding tapered end to seal the valve body 212. When the internal air pressure of the cabinet 100 increases due to the expansion of the piston airbag 220, the ozone-containing gas pushes the ball 213 away from the conical end against the elastic force of the spring 214, causing the valve body 212 to open, and the ozone-containing gas enters the ozone collection bag 200 through the air passage 103; when the internal air pressure drops to close to the external air pressure, the ball 213 presses against the conical end under the action of the spring 214, thereby preventing the gas in the ozone collection bag 200 from flowing back into the cabinet 100.

[0022] Preferably, the shelf 120 has several perforated holes, which allow gas to circulate vertically within the cabinet 100. Since the piston airbag 220 is located above the shelf 120, these perforated holes also allow ozone gas squeezed down from the piston airbag 220 to pass smoothly through the shelf 120 to the air duct 103 inlet at the bottom. A handle 121 is provided on the edge of the shelf 120 near the cabinet door 110 for easy access to items.

[0023] Preferably, the piston airbag 220 includes an upper square corrugated tube 221 and a membrane 222 disposed at the lower end of the square corrugated tube 221. The upper end of the square corrugated tube 221 is fixedly disposed on the inner top surface of the cabinet 100, and the lower end opening is sealed with a flexible membrane 222 (e.g., a silicone membrane or a rubber membrane). The square corrugated tube 221 itself has a retractable and foldable corrugated structure, which can extend downwards when inflated, while the membrane 222 bulges downwards first under air pressure. The advantage of this composite structure is that after the membrane 222 expands, it fits more closely to the top contour of the shoe bag on the lower shelf 120, which can locally compress the space around the shoe bag and reduce gas dead zones; while the square corrugated tube 221 extends downwards as a whole, efficiently filling the volume of the upper part of the cabinet, so that most of the ozone-containing gas in the cabinet is pushed to the bottom air passage 103. The air intake pipe of the miniature fan 130 can be disposed on the top or side of the cabinet 100, as long as it can introduce outside air into the piston airbag 220.

[0024] Preferably, an outlet pipe 104 is connected in series at the end of the air duct 103, and the outlet pipe 104 extends out from the side wall or bottom of the cabinet 100. An air inlet 201 is provided on one side of the ozone collection bag 200, and the air inlet 201 is detachably fitted onto the outside of the outlet pipe 104. An annular sealing ring 3 is fitted around the joint between the air inlet 201 and the outlet pipe 104. The annular sealing ring 3 can be made of elastic rings such as rubber rings or silicone rings. During installation or removal, the user can open the annular sealing ring 3 to fit into or remove it from the joint. After installation, the annular sealing ring 3 tightens the joint between the air inlet 201 and the outlet pipe 104 by its own elastic contraction force, so as to improve the connection stability and reduce gas leakage from the joint. A sealing cap 1041 is detachably installed on the vent pipe 104. The sealing cap 1041 is connected to the vent pipe 104 or the cabinet 100 via a flexible connecting strip to prevent the sealing cap 1041 from being lost. When the ozone collection bag 200 is separated from the vent pipe 104, the sealing cap 1041 can cover the end of the vent pipe 104 to reduce the escape of residual gas inside the cabinet 100 and prevent external dust from entering the vent pipe 104.

[0025] Preferably, an exhaust pipe 105 is provided on the outer side of the cabinet 100 (e.g., the side opposite to the exhaust pipe 104), and an exhaust nozzle 202 is provided on one side of the ozone collection bag 200. The exhaust nozzle 202 is detachably fitted onto the outer side of the exhaust pipe 105. An annular sealing ring 3 is fitted around the joint between the exhaust nozzle 202 and the exhaust pipe 105. The annular sealing ring 3 can be made of elastic rings such as rubber rings or silicone rings. During installation or disassembly, the user can open the annular sealing ring 3 to fit into or remove it from the joint. After fitting, the annular sealing ring 3 tightens the joint between the exhaust nozzle 202 and the exhaust pipe 105 by its own elastic contraction force, thereby improving the connection stability and reducing gas leakage from the joint. The ozone collection bag 200 can be made of a flexible bag body, and the inlet 201 and outlet 202 can be made of flexible nozzles. After collection is completed, the user can directly remove the ozone collection bag 200 and seal the inlet 201 and outlet 202 by bending, knotting, tightening or clamping to reduce ozone gas leakage. A miniature fan 230 is provided at the end of the exhaust pipe 105 for actively discharging the ozone gas from the ozone collection bag 200.

[0026] Preferably, a one-way valve 106 is connected in series on the exhaust pipe 105. The one-way valve 106 is located between the outlet 202 and the miniature fan 230, allowing gas to flow from the ozone collection bag 200 to the miniature fan 230, preventing backflow of external gas. The outlet end of the miniature fan 230 is equipped with a cover 231. Normally, the cover 231 is closed to prevent accidental ozone leakage from the collection bag. When emission is required, the user opens the cover 231 and controls the miniature fan 230 to operate at a lower speed or in an intermittent working mode, allowing ozone to be discharged at a smaller flow rate. Due to the presence of the one-way valve 106, even if the miniature fan 230 stops, the pressure inside the bag is unlikely to cause ozone backflow, thereby reducing the possibility of excessively high local ozone concentrations due to a single emission.

[0027] Working principle: The user places the items to be disinfected on the shelf 120 and closes the cabinet door 110. The sealing strip 111 abuts against the open edge of the cabinet body 100. The ultraviolet lamp 101 is activated, and the 253.7nm ultraviolet light directly sterilizes the items. At the same time, the 185nm ultraviolet light converts the oxygen in the cabinet into ozone, achieving synergistic disinfection. After disinfection, the ultraviolet lamp 101 is turned off, and the miniature fan 130 is activated to inflate the piston airbag 220. The membrane 222 first expands and adheres to the top of the shoes and bags. Then, the square corrugated tube 221 extends downward, squeezing the ozone-containing gas in the cabinet through the hollow holes of the shelf 120 into the groove 102 and the air passage 103, and then into the ozone collection bag 200 through the check valve 210. During collection, the air pressure inside the cabinet 100 pushes the ball 213 to overcome the elastic force of the spring 214 to open the valve 212. After collection is complete, the check valve 210 closes under the action of the spring 214 to prevent the gas in the ozone collection bag 200 from flowing back. After most of the ozone in the cabinet 100 has been transferred, the user can open the cabinet door 110. At this time, the micro fan 130 reverses to draw out the gas in the piston airbag 220, causing it to actively contract, making ample operating space above the shelf 120 so that the shoes and bags can be taken out. The ozone in the ozone collection bag 200 can be removed and taken outdoors for discharge, or it can be slowly released indoors at a low wind speed by the micro fan 230 in conjunction with the one-way valve 106.

[0028] Furthermore, it should be noted that the ultraviolet lamp 101, miniature fan 130, miniature fan 230, and compatible controllers, power supplies, switches, and other electrical components involved in this utility model can all be commonly used components in the field. Specific models can be selected based on the size of the cabinet 100, the capacity of the ozone collection bag 200, and the usage scenario. The power supply and control connections between the various electrical components can be set according to the actual working sequence. For example, it can be set so that after the ultraviolet lamp 101 completes disinfection, the ultraviolet light automatically stops; then the miniature fan 130 starts and runs until ozone collection is complete; subsequently, if the user opens the cover 231 to initiate the emission command, the miniature fan 230 can run intermittently until the gas in the bag is discharged. The above electrical connection methods are all conventional settings that those skilled in the art can make based on the working principle of this utility model, and will not be elaborated further here.

[0029] Those skilled in the art should understand that the above embodiments are merely illustrative of the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can be combined with each other. For example, the shape of the groove 102, the position of the air duct 103, the capacity of the ozone collection bag 200, the specific shape of the piston airbag 220, the specific installation method of the check valve 210, and the relative positions of the one-way air valve 106 and the micro fan 230 can all be adjusted according to the size of the cabinet 100 and the usage requirements. All omissions, modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
