Description

TECHNICAL FIELD

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

[0002] OSA is a common sleep-related breathing disorder, not only has many symptoms such as sleep apnea, night wake-up, daytime sleepiness, night sweating, attention, etc., but also easily causes many complications, which causes unpredictable harm to the user's body and psychology. OSA can cause complications such as cardiovascular disease (OSA users are very prone to develop hypertension, especially night and morning hypertension, which is also related to coronary heart disease, myocardial infarction, atrial fibrillation, heart failure and night angina), endocrine and metabolic system disease (OSA is often associated with insulin resistance, type 2 diabetes, dyslipidemia and metabolic syndrome, which can further aggravate OSA symptoms, forming a vicious cycle), nervous system disease (OSA can cause cognitive dysfunction, memory loss, attention deficit and emotional disorders such as anxiety and depression, and long-term sleep deprivation and intermittent hypoxia can also increase the risk of stroke). Treating OSA can significantly improve these main symptoms and complications. There are many ways to treat, including lifestyle changes, continuous positive airway pressure therapy, oral correction, etc. In some cases where OSA is very severe, the user needs to undergo surgery. In addition to surgical treatment, the above-mentioned treatment methods all require long-term management and treatment, so the treatment device needs to meet the requirements of effectiveness and suitability for long-term wear by the user.

[0003] Among them, continuous positive airway pressure therapy is the most acceptable and preferred treatment method for the public. Continuous positive airway pressure requires components such as continuous positive airway pressure machine (i.e. ventilator), catheter, mask, headband. Among them, the mask is usually composed of a support part and a sealing part, and there are many different styles. Including nose pillow, nasal mask, full-face mask and oral-nasal mask, to adapt to the needs and comfort of different users. When choosing a mask, many factors such as sleeping position, facial structure and personal preference need to be considered, and choosing a relatively more advantageous mask type also has a certain influence on the effect of continuous positive airway pressure therapy.

[0004] Ozone is a strong oxidizing agent that can effectively kill bacteria, viruses, mold and other microorganisms, achieving deep cleaning. After using ozone for cleaning, ozone gas will eventually decompose into oxygen, so there is usually no harmful chemical residue left after disinfection, which is more environmentally friendly than using chemical disinfectants for cleaning and disinfection.

[0005] Proper sanitization can prevent respiratory infections or complications caused by bacteria, mold, and viruses growing on the surface of the device and in the internal tubing from entering the airway of the user through the airflow. Long-term accumulation of dust, pollen, or other allergens in the uncleaned device tubing is particularly dangerous to people with allergies, and can trigger symptoms such as respiratory allergies or asthma. Regular cleaning and sanitization can also reduce the odor of the device, provide fresher airflow, and improve the user experience, thereby increasing the user's compliance with the treatment.

[0047] The ozone disinfection device has at least the following beneficial effects:

[0048] 1) The ozone disinfection device has the following beneficial effects:

[0049] 2) In the ozone disinfection device, various data of the filter material are limited to achieve better filtering effect. First, the specific surface area of the filter material is controlled in the range of 5-500 m 2 / g, preferably in the range of 50-200 m 2 / g, which not only balances the performance and cost of the ozone recovery module, but also enhances the adaptability and application range of the filter material. The filter material with large specific surface area can provide more surface for capturing and adsorbing ozone gas to ensure its cleanliness, while the filter material with moderate specific surface area can provide effective filtering effect while avoiding excessive resistance, so that the airflow can pass through the ozone filter material without obstruction. Therefore, through a large number of experiments, the specific surface area range of the optimized filter material is 5-500 m 2 / g is the more optimal effective range. The optimization of the specific surface area achieves more optimal effects in the aspects of filtration performance, versatility, air flow resistance, cost optimization, service life, environmental protection, etc. Secondly, the porosity range of the filter is specified as 10%-95%, and the porosity range thereof is preferably 50%-85%. Higher porosity can provide more ventilation space, thereby reducing air flow resistance, but can cause the structure of the filter material to be unstable, reduce its durability, and thus reduce the filtration effect. Lower porosity can more effectively adsorb or capture more ozone gas, but can cause the filtration channel to be too narrow to limit the air flow, reduce the filtration efficiency of the ozone recovery device, and too low porosity can also cause the filter material to be blocked, reducing its long-term use reliability. Therefore, it is also found through experiments that in multiple ranges, the filtration effect and use reliability and other aspects are well balanced. In addition, the gas volume sucked by the suction device is greater than or equal to the ozone gas volume generated by the ozone generation module in the same time within the working time of the ozone sterilization device. In this way, the effective action of the suction device in the working time is ensured, and the release of ozone gas with too high concentration to the external environment is avoided, which can cause harm to the environment or users.

[0050] 3) The utility model discloses an integrated sensor in the ozone disinfection device, which significantly improves the intelligence, automation and safety of the ozone disinfection device, thereby optimizing the disinfection effect and ensuring the safety and environmental protection during use. The sensor includes but is not limited to one or more of ozone concentration sensors, temperature and humidity sensors, air pressure sensors, oxygen sensors, flow sensors, volatile organic compound (VOC) sensors, particulate matter sensors, current sensors, and safety lock sensors. The integration of these sensors not only improves the multifunctionality of the device, but also provides users with a more intelligent and efficient operation experience. Specifically, the ozone concentration sensor can monitor the ozone concentration in the device in real time, ensuring that the ozone concentration during disinfection or after recovery remains at the appropriate level, preventing incomplete disinfection due to low concentration or harm to the human body or environment due to high concentration. In addition, the ozone concentration sensor can also detect whether the ozone disinfection device is leaking, thereby detecting the effectiveness of the ozone disinfection device. The temperature and humidity sensor can ensure that the ozone disinfection environment is suitable and optimize the ozone disinfection conditions, thereby improving the efficiency of ozone disinfection. The air pressure sensor and flow sensor can accurately control the distribution of airflow in the disinfection space, ensuring that the ozone gas for disinfection can accurately and meticulously disinfect every part of the components to be disinfected. The oxygen sensor can detect the oxygen content in the recovered ozone disinfection space, which helps to detect whether the ozone is completely recovered, and is beneficial to environmental protection and green design. The oxygen sensor can also be used to detect and adjust the efficiency of ozone generation, thereby adjusting the efficiency of ozone disinfection. Other sensors such as volatile organic compound (VOC) sensors and particulate matter sensors further enhance the device's monitoring of its internal environment and real-time adjustment of whether it is contaminated. The addition of current sensors and safety lock sensors further improves the safety of the device, preventing misoperation and ozone gas leakage. The configuration of one or more of these sensors enhances the intelligence and reliability of the device, providing users with a safer, more reliable, and more efficient ozone disinfection device.

[0051] 4) The filter in the ozone sterilization device of the present application is configured to be replaceable, which has multiple advantages, such as facilitating the maintenance and management of the ozone sterilization device, and improving the sterilization efficiency and service life of the ozone sterilization device. First, the replaceable filter increases the types of filters that can be used by the ozone sterilization device, and users can match filters with different internal filter materials according to different use scenarios and different use requirements. For example, standard versions of ozone filters can be used for ordinary users and in daily environments. Ozone sterilization devices used by users who use ozone devices frequently and sterilize equipment with higher pollution can use filters with higher efficient filter materials. Or users can choose filters with enhanced functions according to specific environments. For example, in a humid environment, users can use filters with enhanced drying functions. This way reduces the impact of the environment on the filter of the ozone sterilization device, to some extent, improves the service life and sterilization efficiency of the ozone sterilization device. As one of the most important functional components of the ozone sterilization device, with the gradual progress of technology, users can also upgrade the ozone sterilization device by replacing more efficient or multifunctional filters, which is advantageous to users and manufacturers, not only saving costs, but also making the device highly scalable. Second, in this way, users can replace filters according to their needs without the need for professional personnel to operate, making the maintenance of the ozone sterilization device more simple and convenient. In one way, users can replace filters by visualizing the status of the filter, which is a more intuitive and convenient way for users. Regularly replacing filters can prevent performance degradation caused by various blockages or aging of the device, effectively protecting and extending the service life of the entire ozone sterilization device. Finally, this way is an environmentally friendly design scheme for ozone sterilization devices. Only the smaller component, the ozone filter, needs to be replaced, instead of replacing the entire ozone sterilization device, reducing the number of discarded devices, and using the same ozone sterilization device with a replaced filter multiple times, which meets the concept of modern green design and is more environmentally friendly.

[0064] In order to make the above purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiment of the utility model is explained in detail below. In the following description, a lot of specific details are set forth in order to fully understand the utility model. But the utility model can be implemented in many other ways different from the description, and the person skilled in the art can make similar improvements without departing from the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0065] Compared with the ozone disinfection device on the market, through the in-depth design and test of the ozone recovery module, the filtration of ozone gas is more thorough and efficient, so that a more environmentally friendly and safer ozone gas emission mode is realized. This meets the strict environmental protection standards, so that the utility model becomes a more environmentally friendly ozone disinfection scheme. And in one of the cases, the utility model integrates a sensor, and the sensor works with the high-efficiency filter, on the one hand, provides accurate data support for the operation of each stage of the ozone disinfection device, to a certain extent, improves the effectiveness and reliability of the ozone disinfection device. On the other hand, the intelligent design improves the overall life of the ozone disinfection device, ensuring that users have a better and more intelligent experience using the ozone disinfection device. Therefore, this design integrating intelligence, high efficiency and environmental friendliness makes the ozone disinfection device can provide a more advanced, more comfortable and friendly ozone disinfection experience for users.

[0066] The following describes several structures of the ozone disinfection device 1 of the utility model in combination with specific examples.

[0067] Example 1

[0068] The utility model provides an ozone disinfection device 1 which is convenient for users to use, improves the use convenience of users and is comfortable to wear.

[0069] Please combine Figures 1 to 10 The ozone disinfection device 1 of the present technical invention comprises an ozone generation module 2 configured to generate and output ozone gas. An ozone recovery module 3 is located downstream of the ozone generation module 2, and the ozone recovery module 3 comprises a suction device 31 and a filter 32 and is configured to suck and filter ozone gas. A control system is configured to control the operation of each component of the ozone disinfection device 1.

[0070] In particular, the ozone generation module 2 and the ozone recovery module 3 and the control system are all functional components of the ozone sterilization device 1, which are all configured to be located inside the housing 4. The housing 4 is configured to form the appearance of the ozone sterilization device 1 and is configured to protect the internal components. The housing 4 also provides stable structural support for the ozone sterilization device 1, ensuring the stability of the device during use and transportation. The housing 4 is composed of multiple walls. In some embodiments, the walls of the housing 4 include an upper cover and a lower cover, wherein the upper cover is configured to be openable, which can be in the form of a flip cover, a sliding cover or any other form. In other embodiments, the housing 4 can also be a housing 4 formed in the form of a drawer or other forms. In some embodiments, the housing 4 also forms at least one sterilization space 44, and the housing 4 constituting the sterilization space 44 is the same housing 4 as the housing 4 storing the internal components. The sterilization space 44 is configured to accommodate the equipment or accessories to be sterilized and release ozone gas in a sealed state for sterilization in the space. The sterilization space 44 and the functional components in the housing are generally arranged in two different separate spaces. In some special cases, the sterilization space and the space storing the functional components can also be communicated. In other embodiments, the sterilization space 44 can also be another housing 4 independently arranged around the housing 4 of the functional components. In this embodiment, the other housing 4 forming the sterilization space 44 can have various forms, and the constituting material can be a single-layer or multi-layer flexible material or a rigid material.

[0071] The ozone generation module 2 is configured to be located inside the housing 4 at all times and in communication with other components. The ozone recovery module 3 is one of the core functional components of the ozone sterilization device 1, which directly affects the performance, efficiency and environmental safety of the device, and is configured to recover and filter ozone gas into harmless oxygen or ozone gas with lower ozone concentration. The ozone recovery module 3 includes a suction device 31 and a filter 32. The suction device 31 can have various forms, and in this embodiment, the suction device 31 is configured as one or more fans or pumps. The filter 32 has a filter material 321 therein, which is used to adsorb and decompose ozone gas (such as activated carbon, zeolite, etc.). Figure 5The filter 32 of the ozone sterilization device 1 can have various forms. For example, in some embodiments, a combination of multiple filter materials 321 is used in the filter 32 of the ozone sterilization device 1 to achieve optimal filtering effect. The multiple filter materials 321 are combined in multiple layers, and different layers of filter materials 321 achieve different filtering effects, such as having both a physical filter layer and a chemical adsorption layer. The physical filter layer is a physical means for screening and intercepting large particulate matter such as dust and bacteria. The physical filter layer can use a HEPA filter screen, a mesh filter layer, a foam filter layer, etc. The chemical filter layer is a chemical reaction between substances. The chemical filter layer includes but is not limited to activated carbon, titanium dioxide, manganese oxide compounds, silica gel adsorption layer, etc. The use of multiple filter materials 321 can provide more comprehensive air purification effect, so that the filter 32 can not only remove large particulate matter, but also adsorb smaller ozone gas and other particles, thereby improving the purification effect and use performance of the ozone sterilization device 1. Multiple layers of the same filter material 321 can also be used to repeatedly filter a single filter material to achieve more thorough filtering effect. In other embodiments, the filter 32 can only have a single layer of filter material 321, in which case the filter material 321 needs to have strong filtering effect. The selection of the filter material 321 can include high-efficiency catalysts such as manganese dioxide, platinum, rhodium, and other noble metal catalysts, or ordinary catalysts such as activated carbon and aluminum oxide, or a combination of both. In addition, specific molecular sieve materials can also effectively adsorb ozone to purify the ozone sterilization device 1. In other forms, the filter 32 can also include HEPA filter material for adsorbing small particles to prevent the spread of harmful substances while ensuring smooth airflow. Generally, the filter material used in the filter 32 generally has one or more of the following characteristics: high porosity material (a large amount of surface area is conducive to ozone adsorption and catalytic decomposition), high stability material (capable of maintaining stability during ozone decomposition, generally a material with good high-temperature resistance and chemical stability), high catalytic activity material (the material can catalyze ozone decomposition into oxygen after surface treatment or modification), and environmentally friendly material (a non-toxic and environmentally friendly material that can safely filter ozone). The two sides of the filter 3 can also have cotton or mesh for fixing the filter material 321 to enhance the stability and reliability of the filter (as shown in FIG. 8). Figure 8 In addition, the filter material 321 can be fixed by a unique structural design.

[0072] To ensure the effectiveness of the filter material 321, some properties of the filter material 321 in the filter 32 are limited. For example, in the present embodiment, the filtration efficiency of the ozone recovery module 3 is positively correlated with the total surface area of the filter material 321. The filtration efficiency here can be understood as the percentage of the filtration capacity of the filter material for the target substance, which can be further defined by the formula: (the mass of the ozone gas entering the filter - the mass of the filtered ozone gas) / the mass of the ozone gas entering the filter. The filter material 321 in the filter 32 has a filtration efficiency of at least 70%. The specific surface area of the filter material 321 ranges from 5-500 m 2 / g, preferably, the specific surface area thereof ranges from 50-200 m 2 / g. The specific surface area refers to the total surface area possessed by the unit mass of the material, which is usually expressed by m 2 / g (square meters / gram) or cm 2 / g (square centimeters / gram), including the external surface area of the material (the external surface of the material, such as the external part of the filter material 321) and the internal pore surface area (the surface area of the internal pores of the material, mainly existing in the porous structure). The filter material 321 with a larger specific surface area can provide a larger surface for capturing and adsorbing ozone gas, ensuring its cleanliness, while the filter material 321 with a moderate specific surface area can provide effective filtration effect while avoiding excessive resistance, so that the airflow can pass through the ozone filter material 321 without obstruction. The present utility model controls the specific surface area of the filter material 321 in the effective range through experiments to improve the reliability of the ozone sterilization device 1 (as shown in Figure 6 、 Figure 7 , Figure 7 , which shows the adsorption effect of different filter materials 321 in the ozone filter 3 on ozone gas). For example, in some embodiments, the filter material in the filter 3 can be manganese dioxide, which has a specific surface area of 50 m 2 / g-300 m 2 / g; aluminum oxide material, which has a specific surface area of 200 m 2 / g-300 m 2The porosity of the filter 32 ranges from 10% to 95%. Preferably, the porosity ranges from 50% to 85%. The porosity herein refers to the ratio of the volume of the voids in the filter material 321 to the total volume, usually expressed in percentage (%). A higher porosity means more voids in the filter material 321, which can provide more space for air flow and reduce the air flow resistance. However, a higher porosity can also result in a less stable structure of the filter material 321, which can reduce the durability of the filter material 321 and thus reduce the filtering effect. A lower porosity can result in a more effective adsorption or capture of ozone gas. However, a lower porosity can also result in a narrower filter channel, which can limit the air flow and reduce the filtering efficiency of the ozone recovery device 3. A lower porosity can also result in a clogging of the filter material 321, which can reduce the long-term reliability of the ozone recovery device 3. Figure 9 Figure 9 The porosity of the filter material 321 in the ozone filter 3 is shown in Table 1. The data in Table 1 is also tested to obtain the optimal porosity of the filter material 321. In addition, the total weight of the filter material 321 is required to be greater than 1.55 g, which is to ensure the filtering quality of the filter material 321.

[0073] The ozone recovery module 3 also has at least one gas outlet 41 configured to discharge gas. The gas outlet 41 is located downstream of the ozone sterilization space 44, specifically, the gas outlet 41 is located downstream of the filter 32. In addition, the gas outlet 41 is configured to be connected to the ozone recovery module 3 to ensure that the discharged ozone is treated to be harmless oxygen or low-concentration ozone, which can meet the environmental protection requirements.

[0074] The ozone generation module 2, the suction device 31, and the filter 32 are in communication with each other. The three components can be connected through an ozone distribution pipeline 45. The ozone distribution pipeline 45 is configured as a conduit in any form that allows gas to pass through, which is used to connect the components and allow the gas to flow between the components through the distribution pipeline 45. The ozone distribution pipeline 45 is made of a corrosion-resistant and impermeable material to avoid leakage of ozone during transmission and to protect the safety of the device and the user. The ozone distribution pipeline 45 is flexibly arranged according to the layout of the functional components in the independent housing 4 to realize the ozone gas conveying path under different spatial layouts. In some embodiments, the ozone distribution pipeline 45 can also be used with a check valve or a regulating valve, which is configured to control the flow of the gas flow and prevent the backflow of the ozone gas, which can further increase the safety and reliability of the ozone sterilization device 1.

[0075] ​In general, the ozone generation module 2 and the ozone recovery module 3 are in the same space in the ozone disinfection device 1. The relative positions of the ozone generation module 2, the suction device 31, and the filter 32 can have various forms of relative position arrangements. Among them, the suction device 31 and the filter 32 are located downstream of the ozone generation module 2. The downstream is defined in terms of the flow route of the ozone gas, that is, it can be understood that the suction device 31 and the filter 32 can be present at any position after the ozone gas flows out of the ozone generation module 2. In one form, the suction device 31 is located downstream of the filter 32, in which form, the ozone gas is first filtered by the filter 32, thus to some extent, it also avoids high-concentration ozone gas or particulate matter entering the suction device 31, which can make the suction device 31 less contaminated and thus prolong its service life. In another case, the suction device 31 can also be located upstream of the filter 32.

[0076] In addition to the above components, the housing 4 of the ozone disinfection device 1 generally also includes a control system, which is responsible for coordinating and managing the smooth operation of the above-mentioned components, and automatically adjusting the working state of the ozone generation module 2, the suction device 31, the filter 32 and other components according to the preset working mode, to ensure that the device performs the disinfection process efficiently and safely. In addition, in some cases, the control system also has a fault diagnosis function, which can detect abnormal conditions in time and trigger an alarm or a shutdown protection to prevent equipment damage or harm to the environment and users. When the ozone disinfection device 1 has an alarm function, the alarm function is generally matched with the user operation interface. Specifically, when the device fails, the alarm system can be linked with other components in the housing 4, so as to quickly locate and pretreat the problem part, avoid more serious damage to the device due to continuous action, and also facilitate the subsequent maintenance personnel to locate and treat the device. This alarm system improves the safety guarantee for the user, optimizes the user experience, and enables the product to perform effective disinfection in a safer and more reliable manner. The alarm system can also be matched with the above-mentioned user operation interface to remind the user.

[0077] In addition, the ozone disinfection device 1 can also have an ozone operation system designed to provide users with a more convenient operation experience and rich functional feedback. The operation system includes but is not limited to one or more display screens, indicator lights, buttons, interfaces, etc. Design, these components provide users with more convenient operation and more rich function indication. The display screen, indicator light and other user operation interfaces can display the working progress of the ozone disinfection device 1, including the percentage of the total working time or the countdown of the working time, and can also be used to indicate parameter settings and fault warning information, so that users can clearly understand the current working progress and running state of the equipment. Among them, the design of the indicator light can prompt the user to the state of the device through different colors or flashing modes. In other embodiments, the ozone disinfection device 1 can not have a related ozone operation system for control, and can have other control forms such as a voice system.

[0078] In the utility model, the ozone gas volume generated by the ozone generation module 2 in the use time of the ozone disinfection device 11 is sufficient to make the ozone concentration in the external disinfection space 44 not less than the concentration value that can kill the conventional bacteria in the respiratory related equipment and its accessories, and ensure that the bacteria in the respiratory related equipment and its accessories can be completely killed. The accessories include but are not limited to masks, nasal masks, hoses and frames commonly used with respirators. And in the working time of the ozone disinfection device 1, the gas volume sucked by the suction device 31 is greater than or equal to the ozone gas volume generated by the ozone generation module 2 at the same time, which ensures that the ozone gas in the external disinfection space 44 can be completely converted into harmless gas by the filter device, preventing harm to the human body or the environment.

[0079] In this embodiment, the disinfection path of the ozone disinfection device 1 is that the ozone generation module 2 in the shell 4 generates ozone gas and delivers it to the interface 42 through the ozone distribution pipeline 45, and then transmits the ozone gas to the external disinfection space 44 through the hose connected with the interface 42 for disinfection of the respiratory related equipment or accessories. The ozone gas after disinfection is recycled to the ozone recycling module 3 in the shell 4 through one or more suction devices 31 and the same hose, and then discharged from the shell 4. The hose here can be understood as any pipe that can be used to deliver gas, which can have any form.

[0080] In other embodiments, during the working time of the ozone disinfection device 1, the suction device 31 and the filter 32 are in the same running state or non-running state. It can be understood that the suction device 31 and the filter 32 are configured to act simultaneously.

[0081] In other embodiments, during the ozone recycling step, the hose for recycling ozone gas and the hose for delivering ozone to the external disinfection space 44 are not the same.

[0082] In some other embodiments, the ozone sterilization device 1 can be equipped with more than one filter 32, and multiple filters 32 can be placed at different locations of the ozone sterilization device 1. For example, in one of the cases, the ozone sterilization device 1 has at least two filters 32, and is configured to be connected to the ozone sterilization space 44 and the hose respectively. The two filters 32 can have the same or different effects.

[0083] In some other embodiments, the filter 32 has a self-cleaning technology, such as blowing back by air flow or vibration to remove particles attached to the filter 32, thereby prolonging the service life of the filter 32.

[0084] Embodiment 2

[0085] The ozone sterilization device 1 of the present embodiment comprises: an ozone generation module 2 configured to generate and output ozone gas. An ozone recovery module 3 located downstream of the ozone generation module 2, the ozone recovery module 3 comprising a suction device 31 and a filter 32, and being configured to suck and filter ozone gas. A control system configured to control the operation of the components of the ozone sterilization device 1. The control system comprises at least one sensor.

[0086] The difference between the present embodiment and Embodiment 1 is that the ozone gas further comprises at least one sensor (such as Figure 11 The sensor shown in Figure 11 The sensor shown in the present embodiment is an ozone concentration sensor. The ozone concentration sensor is configured to be able to monitor the concentration of ozone gas at various places of the ozone sterilization device 1 in real time, to ensure that the concentration of ozone gas generated by the ozone generation module 2 is within the normal range, and to prevent potential health or ecological hazards to users or the environment caused by abnormal ozone control system. In addition, the ozone concentration sensor can be linked with other components in the housing 4, such as the ozone generation module 221, to achieve an output of 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 sense of trust in the product. The sensor in the ozone sterilization device 1 can also be used in cooperation with an alarm system. The alarm function is configured to inform the user in a visual or audible manner when the sensor detects an abnormality or when the user does not use it correctly, thereby preventing the occurrence of potentially greater harm. The abnormal conditions include excessively high ozone concentration, excessively high component temperature, filter 32 failure or blockage, abnormal current, component function failure, seal leakage, etc.

[0087] The sensor can be located at any position of the ozone sterilization device 1 to achieve different effects, for example, it can be located in the sterilization space to ensure that the ozone concentration during the sterilization process is always within the effective and safe range, preventing the release of ozone concentration that is too high from causing harm to the environment or the ozone concentration that is too low resulting in poor sterilization effect. The sensor can also be located at the ozone gas recovery position to monitor the quality of the recovered air to ensure that the residual ozone has been completely removed.

[0088] In other embodiments, the sensors of the ozone control system can also have other types, including but not limited to one or more of temperature and humidity sensors, air pressure sensors, oxygen sensors, flow sensors, volatile organic compound (VOC) sensors, particulate matter sensors, current sensors, and safety lock sensors.

[0089] Embodiment 3

[0090] The ozone sterilization device 1 of the present embodiment comprises: an ozone generation module 2 configured to generate and output ozone gas. An ozone recovery module 3 located downstream of the ozone generation module 2, the ozone recovery module 3 comprising a suction device 31 and a filter 32, and being configured to suck and filter ozone gas. A control system configured to control the operation of the components of the ozone sterilization device 1. The filter 32 of the ozone sterilization device 1 is configured to be replaceable.

[0091] The difference between the present embodiment and Embodiment 1 is that the filter 32 can be replaced, and is configured in a modular design to facilitate user maintenance (such as replacement of the filter 32). Figure 12The service life of the filter 32 is mainly affected by the concentration of the ozone gas, the frequency of use and the working conditions. Generally speaking, as the ozone sterilization device 1 is continuously used, the filter 32 will gradually adsorb the ozone gas, and thus its filtering effect will decrease over time. In order to ensure the effectiveness and safety of the ozone sterilization device 1, in the present embodiment, the housing 4 is designed in cooperation with the filter 32 to achieve convenient replacement of the filter 32. In one case, the housing 4 is provided with a closable and openable panel at the installation position of the filter 32, which can be easily opened by the user to take out and replace the filter 32. The filter 32 itself adopts a detachable and assembled structure design, so that the replacement process is quick and simple. Through this modular structure, the user can regularly check the service status of the filter 32 and determine whether the filter 32 can continue to be used. The user can also quickly replace the filter 32 when the filter 32 is invalid or reaches the service life, without the need to disassemble or discard the entire device. This not only improves the maintenance efficiency of the equipment, but also reduces the maintenance cost. In addition, the replaceable design of the filter 32 also enhances the sustainability of the equipment, so that the ozone sterilization device 1 can maintain high sterilization efficiency and environmental performance during long-term use. The user can keep the equipment in the best working state through simple operation, ensuring the stability and reliability of long-term use.

[0092] In other embodiments, the ozone recovery module 3 or the filter 32 is configured as an independent part that is not combined with other functional components in the housing 4. For example, when the sterilization space 44 of the ozone sterilization device 1 is external, that is, the sterilization space 44 is separated from other components of the ozone sterilization device 1 as a separate part. In this case, the ozone recovery module 3 or the filter 32 can be configured as a separate component connected to the sterilization space 44. In this case, the ozone generation module 2 and the ozone recovery module 3 are in different spaces of the ozone sterilization device 1.

[0093] In addition, the technical features in the above embodiments can be combined as needed to obtain an ozone sterilization device 1 including all or part of the above technical features.

[0094] The ozone sterilization device 1 of the present application has at least the following beneficial effects:

[0095] 1) The present technology invention compares the existing market ozone disinfection device 1, using more efficient filtering technology to bring users a better experience, making the removal of ozone more thorough, thereby significantly improving the environmental friendliness of the exhaust air. Specifically, the filter 32 of the present application adopts an optimized material and structural design. These materials can have multiple layers combined to achieve different filtering functions, such as having a physical filter layer, a chemical adsorption layer, etc. at the same time. At the same time, its structure is scientifically designed, which effectively improves the efficiency of ozone decomposition and filtration. In addition, the ozone disinfection device 1 of the present application reduces the need for frequent replacement of the ozone disinfection device 1 or the filter 32 through the optimized design of the filter 32, maximizes the use efficiency of each layer of filtering material, thereby reducing the use cost and material waste, reducing the maintenance cost of the device, making it more environmentally friendly. Through this innovative design, not only the overall performance of the ozone disinfection device is improved, but also the requirements of environmental protection and sustainable development are further met. It not only has a breakthrough in function, but also makes a positive contribution to environmental protection, resource conservation and sustainability, making it a more efficient, safe and environmentally friendly disinfection solution.

[0096] 2) In the present application, various data of the filtering material 321 are limited to achieve better filtering effect. First, the specific surface area of the filtering material 321 is controlled in the range of 5-500m 2 / g, preferably, the specific surface area thereof is in the range of 50-200m 2 / g, which not only balances the performance and cost of the ozone recovery module 3, but also enhances the adaptability and application range of the filtering material 321. The filtering material 321 with larger specific surface area can provide more surface for capturing and adsorbing ozone gas to ensure its cleanliness, while the filtering material 321 with moderate specific surface area can provide effective filtering effect while avoiding excessive resistance, so that the airflow can pass through the ozone filtering material 321 without obstruction. Therefore, through a large number of experimental verification, the specific surface area of the filtering material 321 is in the range of 5-500m 2 / g is the more optimal effective range. The optimization of the specific surface area achieves more optimal effects in the aspects of filtration performance, versatility, air flow resistance, cost optimization, service life, environmental protection, etc. Secondly, the porosity range of the filter 32 is specified as: 10%-95%, and the porosity range thereof is preferably: 50%-85%. A higher porosity can provide a larger ventilation space, thereby reducing the air flow resistance, but can cause the structure of the filter material 321 to be unstable, reduce the durability thereof, and thus cause the filtration effect to be reduced. A lower porosity can more effectively adsorb or capture more ozone gas, but can cause the filtration channel to be too narrow to limit the air flow, reduce the filtration efficiency of the ozone recovery device 3, and a too low porosity can also cause the filter material 321 to be blocked, reduce the long-term use reliability thereof. Therefore, it is also obtained through experiments that a good balance between the filtration effect and the use reliability, etc. is achieved in multiple ranges. In addition, it is specified that the volume of the gas sucked by the suction device 31 is greater than or equal to the volume of the ozone gas generated by the ozone generation module 3 in the same time within the working time of the ozone sterilization device 1. In this way, the effective action of the suction device 31 in the working time is ensured, and the release of the ozone gas with too high concentration to the external environment is avoided, which can cause harm to the environment or the user.

[0097] 3) The utility model discloses an integrated sensor in the ozone disinfection device 1, significantly improve the intelligentization, automation and security of ozone disinfection device 1, thereby optimize the disinfection effect, and ensure the security and environmental protection in the use process. The sensor includes but is not limited to one or more of ozone concentration sensor, temperature and humidity sensor, barometric pressure sensor, oxygen sensor, flow sensor, volatile organic compound (VOC) sensor, particulate matter sensor, current sensor, safety lock sensor. The integration of these sensors not only improves the multifunctionality of the device, but also provides users with a more intelligent and efficient operation experience. Specifically, the ozone concentration sensor can monitor the ozone concentration in the device in real time, ensure that the ozone concentration during disinfection or after recovery remains at the appropriate level, prevent incomplete disinfection caused by too low concentration or harm to the human body or environment caused by too high concentration. In addition, the ozone concentration sensor can also detect whether the ozone disinfection device 1 is leaking, thereby detecting the effectiveness of the ozone disinfection device 1 disinfection. The temperature and humidity sensor can ensure that the ozone disinfection environment is suitable, and adjust and optimize the ozone disinfection conditions, thereby improving the efficiency of ozone disinfection. The barometric pressure sensor and flow sensor can accurately control the distribution of airflow in the disinfection space 44, ensuring that the ozone gas for disinfection can accurately and meticulously disinfect every part of the component to be disinfected. The oxygen sensor can detect the oxygen content in the recovered ozone disinfection space 44, which helps to detect whether the ozone is completely recovered, and is beneficial to environmental protection and green design. The oxygen sensor can also be used to detect and adjust the efficiency of ozone generation, thereby adjusting the efficiency of ozone disinfection. Other sensors such as volatile organic compound (VOC) sensor, particulate matter sensor, etc. further enhance the monitoring of the internal environment of the device and the real-time adjustment of whether it is polluted. The addition of current sensor and safety lock sensor is to further improve the use safety of the device, prevent misoperation and ozone gas leakage. The configuration of one or more of these sensors enhances the intelligence and reliability of the device, and can provide users with a safer, more reliable and more efficient ozone disinfection device 1.

[0098] 4) The filter 32 in the ozone sterilization device 1 of the present application is configured to be replaceable, which has multiple advantages, such as facilitating the maintenance and management of the ozone sterilization device 1, and improving the sterilization efficiency and service life of the ozone sterilization device 1. First, the replaceable filter 32 increases the types of filters 32 that can be used by the ozone sterilization device 1, and users can match filters 32 with different internal filter materials 321 according to different use scenarios and different use requirements. For example, standard versions of ozone filters 32 can be used for ordinary users and in daily environments. For users who use ozone devices frequently and use ozone sterilization devices 1 to sterilize equipment with higher pollution, filters 32 with higher efficient filter materials 321 can be used. Or users can choose filters 32 with specific function-enhanced filter materials 321 according to specific environments, such as in humid environments, filters 32 with dry function-enhanced filter materials 321 can be used. This way reduces the influence of the environment on the filter 32 of the ozone sterilization device 1, to some extent, improves the service life and sterilization efficiency of the ozone sterilization device 1. As one of the most important functional components in the ozone sterilization device 1, with the gradual progress of technology, users can also upgrade the ozone sterilization device 1 by replacing more efficient or multifunctional filters 32, which is advantageous to users and manufacturers, not only saving costs, but also making the device more scalable. Second, in this way, users can replace the filter 32 according to their needs without the need for professional personnel to operate, making the maintenance of the ozone sterilization device 1 more simple and convenient. In one way, users can replace the filter 32 by visualizing the status of the filter 32, which is a more intuitive and convenient way for users. Regularly replacing the filter 32 can also prevent performance degradation caused by various blockages or aging of the device, effectively protecting and extending the service life of the entire ozone sterilization device 1. Finally, this way is an environmentally friendly design of the ozone sterilization device 1. Only the smaller component, the ozone filter 32, needs to be replaced, instead of replacing the entire ozone sterilization device 1, reducing the number of discarded devices, and using the same ozone sterilization device 1 with a replaced filter 32 multiple times, which meets the concept of modern green design and is more environmentally friendly.
