Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of ozone disinfection device for disinfecting breathing-related device and its accessories, the device is configured to distribute ozone into the pipeline connected with breathing-related device and / or the accessory of breathing-related device, and output ozone to clean disinfect. BACKGROUND

[0002] Obstructive sleep apnea (OSA) is a common sleep breathing disease, and its proportion in respiratory-related diseases is quite significant. According to the statistics and analysis of relevant documents, according to the diagnostic criteria of American Sleep Medicine Association (AASM), it is found that about 936 million adults aged 30 to 69 in the world suffer from mild to severe OSAS, of which 425 million adults aged 30 to 69 suffer from moderate to severe OSAS. About 26% of American adults between 30 and 70 are affected by OSA, i.e. 5 or more respiratory pauses or hypopnea events occur per hour. OSA also affects 34% of men and 17% of women aged 30 to 70 in the United States. In addition, studies have shown that globally, it is estimated that about 936 million adults suffer from mild to severe OSA, of which about 425 million adults suffer from moderate to severe OSA.

[0003] There are various ways to treat obstructive sleep apnea, including lifestyle changes, oral appliance therapy, continuous positive airway pressure therapy, and various surgical treatments. Among them, continuous positive airway pressure therapy is the treatment method of choice for most users. This treatment method includes continuous positive airway pressure equipment, breathing conduit, headband, and user interface pad including mask, nasal mask, oral-nasal mask, etc. The continuous positive airway pressure equipment needs to be used by the user for a long time and for a long period, and the user needs to wear it continuously during sleep. Therefore, the cleaning of the equipment and accessories is crucial for the user.

[0004] Respiratory equipment and accessories come into prolonged contact with the user's respiratory tract. Suitable temperature and humidity conditions can create a breeding ground for bacteria, viruses, fungi, and other pathogens. Failure to regularly disinfect equipment and accessories allows these pathogens to directly enter the body through the respiratory tract, causing respiratory illnesses or other more serious infections, especially for users with weakened immune systems. Therefore, all components of respiratory equipment (such as masks, tubing, and water tanks) should be cleaned regularly. Choosing appropriate disinfection methods and materials for respiratory equipment has a significant impact on user health. Improper disinfection may cause respiratory illnesses such as pneumonia and sinusitis, and can be exacerbated by the accumulation of bacteria or mold. Furthermore, incorrect cleaning or disinfection methods may cause equipment components to age or break, affecting the normal lifespan of the equipment. Accumulated contaminants may also obstruct normal airflow, thus affecting the effectiveness of the respiratory equipment and reducing the therapeutic effect for users with sleep apnea. Therefore, regular and proper cleaning and disinfection of respiratory equipment is crucial to ensure the hygiene and functionality of the equipment and the health and safety of the user.

[0005] Ozone, as one of the most effective oxidants and disinfectants available on the market, can typically reduce the number of microorganisms by 5-6 logs within 2-3 minutes. Its action is safe and controllable, making it an ideal method for disinfecting respiratory equipment and accessories. Ozone technology is a novel disinfection method that effectively eliminates bacteria and viruses. Ozone sterilizers have become the preferred choice for some CPAP equipment users because they can penetrate equipment ducts for comprehensive disinfection and elimination of pathogens.

[0053] The ozone sterilization device of the utility model has at least the following beneficial effects:

[0054] 1) The ozone disinfection device of the utility model not only is convenient to use, but also has the function of recycling compared with the ozone disinfection device on the market, further improving the safety, effectiveness and reliability of the device on the basis of convenience. First, the portable ozone disinfection device has the characteristics of lightness and easy carrying, providing great convenience for users. Compared with the integrated ozone disinfection device on the market, the present application is more suitable for use in different scene states, such as travel, outdoor environment, etc., enhancing the use flexibility of the product and making it not limited by environmental factors. This convenient moving method can also reduce the dependence on storage and transportation conditions and reduce the cost of transportation and storage. Moreover, the ozone disinfection device of the utility model adds the recycling function compared with the existing products on the market, so that the ozone gas can be effectively treated after the use of the device, reducing the harm of ozone gas to the environment or users. The portable ozone device with ozone recycling system has environmental benefits compared with other portable ozone disinfection devices on the market under the same function, and meets the requirements of green development. The ozone recycling system can effectively convert ozone gas into oxygen after disinfection, avoiding excessive release of ozone gas into the environment. In the traditional disinfection process, ozone gas is often directly discharged after disinfection, which not only causes resource waste, but also increases the energy consumption of the device. Through the ozone recycling system, the device can maximize the recovery of ozone gas, thereby saving energy and reducing pollution during operation. The ozone recycling system in the utility model meets relevant environmental regulations, helps users meet environmental standards by reducing ozone gas leakage, and avoids environmental pollution caused by improper use of the device. In the background of the era of increasing emphasis on environmental protection, this environmentally friendly design can enhance the social responsibility of users and producers. In summary, the portable ozone disinfection device provides users with efficient and flexible disinfection experience with higher mobility and adaptability, expands its application range, and meets the requirements of users for green, efficient and convenient disinfection devices, with strong social value.

[0055] 2) At the same time, this portable ozone disinfection device with recyclable performance prolongs the service life of the device and reduces the replacement cost of the device. Ozone gas has very strong oxidizing property, and when it is in long-term contact with the internal materials of the device, it is easy to cause corrosion or aging effect on the core components of the equipment, thereby causing the performance of the device to decline. Since the structure of the portable ozone disinfection device is relatively simple, in order to reduce the size of the device, it has no redundant complex structure. If the internal gas path of the device is not completely sealed, it is very likely to cause damage to the sensor or electronic components, especially some elements sensitive to oxidation reaction. The utility model not only uses corrosion-resistant materials to make the ozone disinfection device shell, but also uses the ozone recovery system to reduce the accumulation of ozone gas in the device and reduce the storage time of ozone gas in the device, prevent ozone gas from flowing back or drifting around, which is crucial to protect the internal materials of the device and prolong the service life of the device. In addition, the external disinfection space can be made of different suitable materials according to the needs of users, providing great flexibility. This diversified selection range not only provides the possibility of lower material cost and diversified manufacturing selection for merchants, but also makes the external disinfection space have different characteristics according to different materials. Such as high temperature resistance, moisture resistance, ultraviolet resistance, corrosion resistance or light weight, etc. Enhance the flexibility of production and manufacturing, more importantly, enhance the adaptability and practicality of the product. Manufacturers can also quickly adjust the scheme according to different market feedback to ensure that the product always matches the market demand, thereby improving the user experience. In addition, the optional materials and optimized design of the external disinfection space can effectively prolong the service life of the equipment and reduce the replacement cost caused by material aging or functional failure.

[0056] 3) The portable ozone disinfection device of the utility model improves the user experience of using the ozone disinfection device by carrying the ozone recovery system. In the process of using the ozone disinfection device for disinfection, if the ozone gas is not automatically recovered by the ozone recovery system, the user needs to manually collect and process the ozone gas or directly discharge it into the environment. First, the high-concentration ozone gas diffused into the environment may pose a threat to the user or the surrounding personnel and the environment. Therefore, without the ozone recovery system, the user's manual collection and processing method is an acceptable and safer ozone gas processing method, but this method requires the user to spend time, and there is still a risk of ozone gas escaping during the processing process. Therefore, the ozone recovery system is designed for the portable ozone disinfection device to further improve the convenience and effectiveness of the user by simplifying the ozone recovery processing steps. In terms of portability of the device, the utility model uses a portable external disinfection space instead of the traditional large volume and weight integrated external disinfection space, so that the external disinfection space can have multiple forms of design, and the same external disinfection space can have multiple forms of change, without being limited by the functional components and shell of the ozone disinfection device. For example, in one way, the external disinfection space is made of flexible materials such as cloth, so that the external disinfection space can be in a folded state in a non-use state. Thus, the volume of the external disinfection space can accommodate the breathing accessory in the use state is increased, and the overall volume of the ozone disinfection device in the non-use state is reduced, thereby improving the portability of the original ozone disinfection device. This flexibility not only makes the ozone disinfection device more portable in daily life, but also improves the practicality of the device, meets the diversified disinfection needs, and also allows the user to disinfect larger and more equipment or accessories, thereby improving the disinfection efficiency.

[0057] 4) The external disinfection space makes the ozone disinfection device more compact, optimized in structure and reduced in cost. Further, in combination with the advantages of the ozone recovery system, the ozone disinfection device is further reduced in cost. The ozone disinfection device of the present application has the functional components designed in a centralized manner, and the external disinfection space is designed independently and fluidly connected with the functional components. This not only reduces the internal complex wiring and component space requirement, but also reduces the matching requirement of the internal space and the disinfection space, thereby effectively reducing the volume of the shell and the amount of material used, which makes the storage and transportation of the ozone disinfection device further relatively convenient and cost controllable. The reduction in cost is also reflected in that the integrated functional components of the separate space make the maintenance and replacement of the ozone disinfection device components more convenient, reducing the difficulty of disassembly and assembly of the product. Since it is a separate component, the sealing between the two spaces does not need to be sealed and tested multiple times. In terms of production, the present application makes the assembly of the product easier, further saving the labor cost and time cost. At the same time, the portable ozone disinfection device of the present application is more convenient to use in the function collection end than the integrated ozone disinfection device, and its function is relatively more single, which can help users understand and operate more quickly, reducing the learning cost of users. This is very important and convenient for users who need to disinfect frequently and for older users. And in one embodiment, the ozone recovery system is configured to be replaced separately, which also separates the ozone recovery system, which can further improve the convenience of the device and reduce the maintenance frequency and difficulty of the user. The user only needs to check the availability of the separate components of the ozone recovery system regularly, and replace them separately when the ozone recovery device is not available.

[0058] 5)The ozone disinfection device provides a modular use possibility for the user, and the design fully considers the diversity of user needs and the potential for future upgrading. The external disinfection space can be increased, reduced or replaced according to the user's needs without affecting its use. If some users have the demand for a larger external disinfection space, they can purchase a larger volume of external disinfection space or increase the number of external disinfection spaces as needed to achieve the demand, which meets the various needs of users. This modular design also greatly facilitates the iterative upgrading of the product. For the developer, it is easier to upgrade the product. When the function integrated end needs to be improved, only the related parts of the core module need to be debugged and upgraded, without changing the structure and specific circuit. At the same time, the disinfection space that cooperates with the space will not be adjusted because of the change of the internal components. In addition, if the external disinfection space needs to be upgraded, only the material, space and the like need to be researched and tested, and the structure and components of the function component end are not affected. This way of developing and testing by modules not only shortens the development cycle, but also reduces the overall development cost. In addition, for the manufacturer, the function integrated end and the external disinfection space of the portable ozone disinfection device can be produced separately without additional assembly, reducing the complexity of the assembly link and improving production efficiency. The characteristics of independent production also facilitate inventory management. Different specifications of external disinfection space can be sold or sold in combination to meet the needs of different users. This design not only provides users with more diversified choices, but also opens up a diversified sales model. BRIEF DESCRIPTION OF DRAWINGS

[0073] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to provide a sufficient understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0074] In the utility model, the functional component end (namely the end of generating and conveying ozone gas and carrying out each function reaction) in the ozone disinfection device and the external disinfection space are physically isolated, so that they are not wrapped by the same shell. In this way, the ozone disinfection device of the utility model is smaller than the popular disinfection device on the market, is convenient to carry and is convenient for the user to use. The separated external disinfection space can be made of different materials according to different user needs or various factors of manufacturer production, greatly improving the selectability of the external disinfection space. At the functional component end, because of the limitation of the external disinfection space, the internal arrangement can be more regular and more compact, and the improvement of the material of the external disinfection space can make the effectiveness and reliability of the ozone disinfection device reach a more optimal state. Therefore, the ozone disinfection device of the utility model not only improves the performance index, but also brings the user a more stable, safe and comfortable use experience.

[0075] The ozone disinfection device 1 of the utility model is described below in combination with specific examples.

[0076] Example 1

[0077] In the utility model, a kind of ozone disinfection device 1 is provided, which is convenient for user to use, improves the use convenience of user and is comfortable to wear. Specifically, please combine Figures 1 to 6 , the ozone disinfection device 1 of the embodiment, comprising: ozone generation system 21, configured to generate and output ozone gas. Ozone recovery system 3, comprising at least one pump or fan, the pump or fan is configured to suck gas. External disinfection space 4 is configured to be fluidly connected to ozone generation system 21, and is configured to accommodate breathing accessories. Wherein, ozone gas is generated from ozone generation system 21 and flows out, is recovered by ozone recovery system 3 after external disinfection space 4. Wherein, the ozone disinfection device also has at least one interface 23, the interface 23 is configured to be fluidly connected to external disinfection space 4. Wherein, the external disinfection space 4 is configured to be sealable and gas-impermeable. Wherein, the ozone disinfection device also includes an ozone operation system 22, configured to control the operation of ozone disinfection device, the ozone operation system 22 has at least one switch.

[0078] The ozone disinfection device 1 is divided into two main parts, namely the functional component end including the shell 2 and the external disinfection space 4. Among them, the ozone generation system 21 and the ozone recovery system 3 belong to the components of the functional component end. These functional components have an independent shell 2 that wraps them. The shell 2 is configured to wrap and support functional components such as ozone generation system 21 and ozone recovery system 3. The shell 2 also provides stable structural support for the ozone disinfection device 1, ensuring the stability of the ozone disinfection device 1 during use and transportation, and avoiding interference from the external environment. The form of the above-mentioned shell 2 can have diversity, and can be designed according to the layout of the internal functional components and the specific functional requirements of the ozone disinfection device 1. Make it meet the needs of stable structure, and improve the maintainability of the equipment. For example, the shell 2 designed by modularization can be quickly disassembled, which is convenient for users or professional maintenance personnel to overhaul or replace internal components. At the same time, it can also adjust the appearance design or size specification according to market demand, improve user experience and market adaptability. High-concentration ozone can cause irritation or damage to the respiratory tract, eyes, and skin of the human body. Long-term exposure to a high-concentration ozone environment can also cause damage to the respiratory system. Therefore, the shell 2 of the functional component end needs to have ozone resistance and sealing performance. The sealing performance may not be formed by the shell 2, but also can be a pipeline that controls ozone gas in the shell 2, so that it does not flow out of the external environment. The material of the shell 2 can have multiple choices. In general cases, the shell 2 can include but not limited to one or more of engineering plastics such as ABS, PC, PPS, PP, metal materials, composite materials, materials with special coatings or plating films. The specific material of the shell 2 of the ozone disinfection device 1 can be considered in combination with various factors according to different use scenarios, market demand, etc.

[0079] The ozone generation system 21 is separated from the external disinfection space 4 and is fluidly connected to the ozone recovery system 3. The ozone recovery system 3 is configured to be downstream of the ozone generation system 21. Here, the downstream is defined in terms of the gas flow path, i.e. it can be understood that the ozone recovery system 3 can be located anywhere downstream of the ozone generation system 21 after the ozone is generated. The ozone recovery system 3 comprises at least one pump or fan, and at least one recovery device. The ozone recovery system 3 is configured to be connected to the ozone generation system 21 and to recover and filter the ozone gas. The pump or fan is configured to draw the ozone gas in the external disinfection space 4 into the ozone recovery device. The recovery device comprises at least one layer of recovery material configured to filter or decompose the ozone gas after disinfection into harmless oxygen gas, preventing the ozone from entering the external environment. In the case of multiple layers of recovery material in the recovery device, the multiple layers of recovery material can have different filtering functions, such as having a physical filter layer, a chemical adsorption layer, an antibacterial layer, etc. In general, the recovery material has manganese-containing particulate matter for catalyzing the decomposition of ozone gas, and in other cases, any other form of any material that catalyzes the decomposition of ozone gas can be used in the recovery device, such as activated carbon, noble metal oxidants, activated alumina, carbon-based composite materials, or transition metal oxides, etc.

[0080] The components at the end of the functional part are connected by the ozone distribution pipeline, which is used to connect the components and make the ozone gas flow between the components. The ozone distribution pipeline is made of corrosion-resistant and impermeable materials to avoid leakage of ozone during transmission and protect the safety of the device and the user. The ozone distribution pipeline is flexibly arranged according to the layout of the functional components in the independent housing 2 to realize the ozone gas conveying path under different spatial layouts. In some embodiments, the ozone distribution pipeline can also be used with check valves or regulating valves, which are configured to control the flow of gas and prevent the backflow of ozone gas, further increasing the safety and reliability of the ozone disinfection device 1.

[0081] In addition, the independent housing 2 of the functional component end also comprises at least one interface 23, which is configured to be connected with the hose 5 and is configured to be fluidly connected to the external disinfection space 4. The hose 5 here can be understood as any tube that can be used to transport ozone gas and can have any form. The ozone disinfection device 1 also comprises at least one gas discharge port, which is located downstream of the external disinfection space 4 and can be located on any component in the external disinfection space 4, the housing 2, or the ozone recovery system 3. The gas discharge port is usually configured to be connected with the ozone recovery system 3, so as to ensure that the discharged ozone is recovered to harmless oxygen or low-concentration ozone, which can meet the environmental protection requirements.

[0082] The external disinfection space 4 is a key point in the utility model for improving the user experience, which is a space for receiving and accommodating breathing-related equipment or accessories thereof and is configured to be fluidly connected to the ozone generation system 21 and is configured to accommodate breathing accessories. As an independent module, the external disinfection space 4 can be replaced and maintained individually in the utility model. This mode is equivalent to modular design of the external disinfection space 4. The external space can have various forms of design and can provide flexible choices for users according to different needs. Users can choose external disinfection spaces 4 of different sizes, functions, and materials, and users can choose to use one or more external disinfection spaces 4 to match the functional component end. When the functional component end of the ozone disinfection device 1 is matched with multiple external spaces, the matching form here can be to use a flow divider (such as a three-way joint 231 or a four-way joint) at the interface 23 of the housing 2 or the hose 5 port, so as to realize the distribution of ozone gas to multiple external disinfection spaces 4 (such as Figure 4 .

[0083] The ozone disinfection device 1 designed in this way reduces the need for sealing points (such as Figure 8 , Figure 9 indicated in the dashed box in Figure 8 . In the ozone disinfection device 1 of the functional component end and the disinfection space integrated in the existing market, the sealing points required by the whole device are at least four (such as Figure 9 indicated in the dashed box), that is, the sealing of the disinfection space and the functional component end is increased. Therefore, the ozone disinfection device 1 of the utility model makes the assembly and disassembly of the product more simple and also makes it more effective.

[0084] The external disinfection space 4 is made of a material that is sealed and resistant to ozone, ensuring that ozone can effectively act during disinfection without leakage, and avoiding aging or degradation of the external disinfection space 4 due to long-term contact with ozone gas. The material of the external disinfection space 4 needs to have multiple properties to ensure efficient, safe and durable use of the disinfection process (such as Figure 5 As shown, the external disinfection space can also have various forms). In one form, the external disinfection space 4 is of a flexible material, which can be a cloth in a foldable form. The cloth can also have the feature of light weight, making it easy for users to store and carry on a daily basis (such as Figure 7 In some cases, this cloth can be repeatedly washed and used to achieve a higher service life of the ozone disinfection device 1. The cloth can have a single layer or multiple layers, and in one form, the external ozone disinfection space 4 is a collection of multiple layers of material, and the different layers of cloth can have different effects to combine to form a more suitable external disinfection space 4. In the case of the external disinfection space 4 being such a flexible material, the material of the external disinfection space 4 can include polyester fiber, nylon, polyester, or neoprene and their composite materials, or coated cloth. In other forms, the external disinfection space 4 can also be a rigid material other than cloth, such as a plastic material (including but not limited to HDPE, PP, PC, PVC), a metal material (including but not limited to stainless steel, aluminum alloy), a silica gel and rubber material, a glass material, or a variety of composite materials. In this form, the external disinfection space 4 can also be in a single layer or multiple layers. When the external disinfection space 4 is in a non-cloth form, the portability of the external disinfection space 4 can be achieved through structural design, such as through structures to achieve foldable, detachable, etc. forms of the external disinfection space. Or using a quick assembly or simple fixing mechanism (such as a slide rail, buckle or magnetic connection) can make the assembly and disassembly of the disinfection space more efficient, to further improve the portability and operational convenience of the disinfection space in the case of a rigid material. To further meet environmental requirements, the external ozone disinfection space 4 can also use recyclable or biodegradable materials, such as bioplastics, high-performance composites, or recycled polymers. These materials not only reduce environmental burden through recycling or natural degradation at the end of the product life cycle, but also reduce dependence on non-renewable resources during the production process.

[0085] In addition, the external disinfection space 4 has an opening, specifically, the external disinfection space 2 has at least one opening that can be switched between open and closed states (such as Figure 3 When the external disinfection space 4 is of a flexible material, its opening form can include but is not limited to a zipper, a magic tape, a drawstring, a buckle, or a suitable elastic seal, etc. various forms or combinations of various forms (such as Figure 6The opening of the external disinfection space 4 can include, but is not limited to, a hinge type, a sliding cover type, a buckle type, a rotating type, a bolt type, a flip cover type, a spring cover type, or a threaded type, or a combination of multiple forms. The opening needs to ensure the airtightness of the external disinfection space 4 when the ozone disinfection device 1 is in operation, so the opening can also be in a form that can be sealed multiple times to further ensure the airtightness of the ozone gas. The interface between the external disinfection space and the hose can be the same as the opening, or can be in a separate form. The interface also has various forms, including but not limited to elastic deformation connection, structural connection, and adhesion.

[0086] In this embodiment, various data of the external disinfection space 4 are limited, for example, the volume of the ozone gas generated by the ozone generation system 21 is at least one-third of the volume of the external disinfection space 4. This volume is the minimum volume to ensure that the ozone gas can cover the external disinfection space 4, thereby achieving effective disinfection. In addition, the volume of the gas sucked by the pump or fan during operation is greater than or equal to the volume of the external disinfection space 4, thereby ensuring the effective recovery of ozone gas in the external disinfection space 4 by the ozone recovery system 21, which is one aspect of the effectiveness of the ozone disinfection device 1. In addition, in the present application, the volume of the ozone gas generated by the ozone generation system 21 during the use of the ozone disinfection device 1 is sufficient to ensure that the ozone concentration in the external disinfection space 4 is not less than the concentration value that can kill the regular bacteria in the breathing-related equipment and its accessories, thereby ensuring that the bacteria in the breathing-related equipment and its accessories can be completely killed. The accessories include, but are not limited to, masks, nasal masks, hoses 5, and frames commonly used with respirators. In addition, the gas suction volume of one or more fans or pumps in the ozone operation system 22 is not less than the ozone gas volume generated by the ozone generation system 21, thereby ensuring that the ozone gas in the external disinfection space 4 can be completely converted into harmless ozone gas by the filtering device, thereby preventing harm to the human body or the environment.

[0087] The ozone disinfection device can also have an ozone operation system 22, including one or more display screens, indicator lights, buttons, etc. designed to provide users with more convenient operation and more comprehensive function instructions. The display screen, indicator light, etc. user operation interface can display the working progress of the ozone disinfection device 11, including the percentage of the total working time or the countdown of the working time. In other embodiments, the operation system 22 in the ozone disinfection device 1 is in other forms such as voice control in addition to the display screen, indicator light, button. In some cases, an important function of the ozone operation system 22 is the alarm function, which is configured to inform the user visually or aurally when the device has an abnormality or when the user has not used it correctly, thereby preventing potential greater harm from occurring. When the device malfunctions, the alarm system can also interact with other components in the ozone operation system 2, thereby quickly locating and pre-processing the problem area, avoiding more serious damage to the device due to continuous action, and also facilitating the maintenance personnel's maintenance positioning and processing of the device. The alarm system improves the safety protection for users, optimizes the user experience, and enables the product to effectively disinfect in a safer and more reliable manner. The alarm system can also cooperate with the above-mentioned user operation interface to remind the user.

[0088] In this embodiment, the disinfection path of the ozone disinfection device 1 is that the ozone generation system 21 in the shell 2 generates ozone gas and delivers it to the interface 23 through the ozone distribution pipeline, and then transmits the ozone gas to the external disinfection space 4 through the hose 5 connected with the interface 23 for disinfection of the breathing-related equipment or accessories. The ozone gas after disinfection is collected to the ozone recovery system 3 in the shell 2 through one or more fans or pumps along with the same hose 5, and then discharged from the gas outlet after reaction.

[0089] In other embodiments, the ozone disinfection device 1 is also equipped with sensors, including but not limited to one or more of ozone sensors, temperature and humidity sensors, air pressure sensors, oxygen sensors, flow sensors, volatile organic compound sensors, particulate matter sensors, ultraviolet light sensors, current sensors, and safety lock sensors. The sensors can be configured to be used in cooperation with the alarm system to effectively improve the safety and intelligent level of the ozone disinfection device 1. The sensors can also interact with components such as the ozone generation system 21 in the functional component end to achieve the output of the intelligent ozone concentration that can be adjusted by the user, giving the user more operating space. At the same time, it can also reduce the waste of energy or consumables, improve the safety and reliability of the equipment, and enhance the user's trust in the product. The sensors can be placed anywhere in the ozone disinfection device, and the sensors placed in different positions can have different functions.

[0090] In some other embodiments, the hose 5 for recovering ozone gas is not the same as the hose 5 for delivering ozone to the external sterilization space 4 (as shown in Figure 2 , Figure 11 .

[0091] In some other embodiments, the ozone distribution pipeline is not provided inside the housing 2, which is made of ozone-resistant material and is configured to be airtight, and the ozone gas generated by the ozone generation system 21 in the housing 2 directly circulates in the housing 2.

[0092] Embodiment 2

[0093] The ozone sterilization device 1 of the present embodiment comprises: an ozone generation system 21 configured to generate and output ozone gas. An ozone recovery system 3 comprising at least one pump or fan configured to suck gas. An external sterilization space 4 configured to be fluidly connected to the ozone generation system 21 and configured to accommodate a breathing accessory. Wherein the ozone gas is generated and flows out from the ozone generation system 21, passes through the external sterilization space 4 and is recovered by the ozone recovery system 3. Wherein the ozone sterilization device further comprises at least one interface 23 configured to be fluidly connected to the external sterilization space 4. Wherein the external sterilization space 4 is configured to be sealable and gas-impermeable. Wherein the ozone sterilization device further comprises an ozone operation system 22 configured to control the operation of the ozone sterilization device, and the ozone operation system 22 comprises at least one switch.

[0094] The difference between the present embodiment and Embodiment 1 is that the ozone recovery system 3 is configured to be connected to the external sterilization space 4 and to recover and filter (as shown in Figure 13 Figure 14 ​The ozone recovery system 3 is arranged at the end of the external disinfection space 4 as a separate component in this embodiment. This design optimizes the structure of the ozone disinfection device 1, as the ozone gas does not need to return to the functional component end but is directly recovered and discharged, making the disinfection process more efficient and convenient. In this embodiment, the path of the ozone gas is as follows: the ozone generation system 21 in the shell 2 generates ozone gas and delivers it to the interface 23 through the ozone distribution pipeline, and then the ozone gas is transmitted to the external disinfection space 4 through the hose 5 connected to the interface 23 to disinfect the breathing-related equipment or accessories, and the disinfected ozone gas is directly discharged from the external disinfection space 4 or the ozone recovery system 3 connected to the external disinfection space 4, without returning to the shell 2 at the functional component end. This design makes the shell 2 at the functional component end smaller in size as it no longer needs to include the ozone recovery system 3 component, thereby making the overall structure more compact and significantly improving portability, making it more suitable for users who travel or use the device temporarily. In addition, the simplified functional component end reduces complexity, reduces potential failure rates, improves the reliability and durability of the device, and thus prolongs the service life of the product. This modular design also brings convenience in maintenance and replacement, and users or maintenance personnel can individually inspect, replace or upgrade the ozone recovery system 3, avoiding the need to disassemble the entire device, improving maintenance efficiency. This design enables higher flexibility and efficiency in production, use and maintenance of the equipment.

[0095] In addition, the technical features in each of the above embodiments can be combined as needed to obtain an ozone disinfection device 1 that includes all or part of the above technical features.

[0096] The ozone disinfection device 1 of the present application has at least the following beneficial effects:

[0097] 1) The utility model discloses not only convenient ozone disinfection device 1 is used, and relative to the ozone disinfection device on the market, added the function of recyclable, further improved the security, effectiveness and reliability of the device on the basis of convenience. First, the ozone disinfection device 1 of convenience has the characteristics of light and easy to carry, provides great convenience for the user. Compared with the integrated ozone disinfection device on the market, the present application is more suitable for use in different scene states, such as travel, outdoor environment, etc., enhances the use flexibility of the product, and makes it not limited by environmental factors. This kind of convenient movement can also reduce the dependence on storage and transportation conditions, reduce the cost of transportation and storage. Moreover, the ozone disinfection device 1 of the utility model adds the recyclable function compared with the existing products on the market, so that the ozone gas can be effectively treated after the use of the device 1, reducing the harm of ozone gas to the environment or the user. The portable ozone device 1 with ozone recovery system 3 has environmental benefits compared with other portable ozone disinfection devices on the market in the same function, and meets the requirements of green development. The ozone recovery system 3 can effectively convert ozone gas into oxygen after disinfection, avoiding excessive release of ozone gas into the environment. In the traditional disinfection process, ozone gas is often directly discharged after disinfection, which not only causes resource waste, but also increases the energy consumption of the device. Through the ozone recovery system 3, the device can maximize the recovery of ozone gas, thereby saving energy and reducing pollution during operation. The ozone recovery system in the utility model meets relevant environmental regulations, reduces the leakage of ozone gas, helps users meet environmental standards, and avoids environmental pollution caused by improper use of the device. In the background of the era of attaching great importance to environmental protection, this kind of environmental design can enhance the social responsibility of users and producers. In summary, the portable ozone disinfection device provides efficient and flexible disinfection experience for users with higher mobility and adaptability, expands its application range, and meets the requirements of users for green, efficient and convenient disinfection devices, with strong social value.

[0098] 2) At the same time, the portable ozone disinfection device 1 with recyclable performance prolongs the service life of the device and reduces the replacement cost of the device. Ozone gas has extremely strong oxidizing property, and when it is in long-term contact with the internal materials of the device, it is easy to cause corrosion or aging effect on the core components of the equipment, thereby causing the performance of the device to decline. Since the portable ozone disinfection device 1 has a relatively simple structure, in order to reduce the size of the device, it has no redundant complex structure. If the internal gas path of the device is not completely sealed, it is extremely likely to cause damage to the sensor or electronic components, especially some elements sensitive to oxidation reaction. The utility model not only uses corrosion-resistant materials to manufacture the ozone disinfection device 1 shell 2, but also uses the ozone recycling system 3 to reduce the accumulation of ozone gas in the device and reduce the storage time of ozone gas in the device, prevent ozone gas from flowing back or drifting around, which is crucial to protect the internal materials of the device and prolong the service life of the device. In addition, the external disinfection space 4 can be made of different suitable materials according to the needs of users, providing great flexibility. This diversified selection range not only provides the possibility of lower material cost and diversified manufacturing selection for merchants, but also makes the external disinfection space have different characteristics according to different materials. For example, high temperature resistance, moisture resistance, ultraviolet resistance, corrosion resistance or light weight, etc. The flexibility of production and manufacturing is enhanced, and more importantly, the adaptability and practicality of the product are enhanced. Manufacturers can also quickly adjust the scheme according to different market feedback to ensure that the product always meets the market demand, thereby improving the user experience. In addition, the optional materials and optimized design of the external disinfection space 4 can effectively prolong the service life of the equipment and reduce the replacement cost caused by material aging or functional failure.

[0099] 3) The portable ozone disinfection device 1 of the utility model carries ozone recovery system 3, improve the user experience of using ozone disinfection device 1. In the process of disinfection of user using ozone disinfection device 1, if there is no ozone recovery system 3 to automatically recycle ozone gas, then the user needs to manually collect ozone gas for processing, or directly discharge to the environment. First, high concentration ozone gas diffuses to the environment may threaten the user or the surrounding personnel and the environment. The user manually collects the processing mode is an acceptable safer ozone gas processing mode, but this way needs to spend the time of user, and in the processing process, ozone gas still has the risk of diffusion. Therefore, the portable ozone disinfection device 1 is designed with ozone recovery system 3, which further improves the convenience and effectiveness of the user by simplifying the ozone recovery processing steps. In terms of portability of the device, the utility model uses portable external disinfection space 4 instead of traditional larger volume and weight integrated external disinfection space, so that the external disinfection space 4 can have multiple forms of design, and the same external disinfection space 4 can have multiple forms of change, without being limited by the functional components and shell 2 of the ozone disinfection device 1. For example, in one way, the external disinfection space 4 is made of flexible materials such as cloth, so the external disinfection space 4 can be in a folded state in a non-use state. Thus, the volume of the external disinfection space 4 can be increased in the use state, and the overall volume of the ozone disinfection device 1 in the non-use state is reduced, thereby improving the portability of the ozone disinfection device 1. This flexibility not only makes the ozone disinfection device 1 more portable in daily life, but also improves the practicality of the device, meets the diversified disinfection needs, and also enables the user to disinfect larger and more equipment or accessories, thereby improving the disinfection efficiency.

[0100] 4) The external disinfection space 4 makes the ozone disinfection device more compact, optimized in structure and reduced in cost. Further, in combination with the advantages of the ozone recovery system, the ozone disinfection device 1 is further reduced in cost. The ozone disinfection device 1 of the present application has the functional components designed centrally, and the external disinfection space 4 is designed independently and fluidly connected with the functional components. This not only reduces the internal complex wiring and component space requirement, but also reduces the matching requirement of the internal space and the disinfection space, thereby effectively reducing the volume of the shell 2 and the amount of material used, which makes the storage and transportation of the ozone disinfection device 1 further relatively convenient and cost controllable. The reduction in cost is also reflected in that the integrated functional components of the separate space make the maintenance and replacement of the components of the ozone disinfection device 1 more convenient, reducing the difficulty of disassembly and assembly of the product. Since it is a separate component, the sealing between the two spaces does not need to be structurally designed and tested multiple times. In terms of production, the present application makes the assembly of the product easier, further saving labor cost and time cost. At the same time, the portable ozone disinfection device 1 of the present application is more convenient to use in terms of function collection end compared to the integrated ozone disinfection device 1, and its function is relatively more single, which can help users understand and operate more quickly, reducing the learning cost of users. This is very important and convenient for users who need to disinfect frequently and for older users. And in one embodiment, the ozone recovery system 3 is configured to be replaced separately, which also separates the ozone recovery system 3, which can further improve the convenience of the device and reduce the maintenance frequency and difficulty of the user. The user only needs to check the availability of the separate components of the ozone recovery system 3 regularly, and replace them separately when the ozone recovery device 1 is not available.

[0101] 5) The ozone disinfection device 1 provides a modular use possibility for the user, and the design fully considers the diversity of user needs and the potential for future upgrades. The external disinfection space 4 can be increased, reduced or replaced according to the user's needs without affecting its use. If some users have the need for a larger external disinfection space 4, they can purchase a larger volume of external disinfection space 4 or increase the number of external disinfection spaces 4 as needed to achieve, adapting to the diverse needs of users. This modular design also greatly facilitates the iterative upgrade of the product. For the developer, it is easier to upgrade the product. When the function integration end needs to be improved, only the related components of the core module need to be debugged and upgraded, without changing its structure and specific circuit. At the same time, it will not adjust the disinfection space 4 that cooperates with the space because of the change of the internal components. In addition, if the external disinfection space 4 needs to be upgraded, only the material, space, etc. of the external disinfection space 4 needs to be researched and tested, and the structure and components of the function component end have no effect. This way of developing and testing by module not only shortens the development cycle, but also reduces the overall development cost. In addition, for the manufacturer, the function integration end and the external disinfection space 4 of the portable ozone disinfection device 1 can be produced separately without additional assembly, reducing the complexity of the assembly process and improving production efficiency. The characteristics of independent production also facilitate inventory management. Different specifications of external disinfection spaces can be sold or sold in combination to meet the needs of different users. This design not only provides users with more choices, but also opens up a diversified sales model.
