[0029] Please combine Figure 1-Figure 5 The first embodiment of the utility model provides a closed environment deodorization and disinfection device 1, which includes a box body 10 and a transfer unit 11, an ultraviolet disinfection unit 12, and a high-energy ion disinfection unit 13 and an active deodorization unit 14 arranged in sequence near the ultraviolet disinfection unit 12. The transfer unit 11 includes a fan 110, and the fan 110 is provided with an air inlet 111 and an odor treatment channel connected to the air inlet 111, and a filter element is arranged near the air inlet 111. The ultraviolet disinfection unit 12, the high-energy ion disinfection unit 13 and the active deodorization unit 14 are arranged in sequence in the odor treatment channel according to the order of odor treatment.

[0030] Specifically, a deodorization and disinfection device 1 for a closed environment in an embodiment of the utility model can be used for deodorization and disinfection treatment in toilets, farms or garbage transfer stations; it should be noted that a closed environment refers to a space that is relatively isolated from the external environment. If the air quality in a closed environment is polluted, it will not only affect the comfort of people or poultry, but may also pose a threat to their health.

[0031] Preferably, the entire device can achieve human-machine coexistence, and it does not require the user to leave to sterilize and disinfect the odor generated in the air, which is harmless to the human body and has higher flexibility; it can be explained that the closed environment deodorization and disinfection equipment 1 is mainly used for deodorization and disinfection of toilets, especially for public toilets with many squatting seats, units or mobile toilets with heavy odors and relatively closed environments, and with a larger flow of people. Environmental disinfection and deodorization in an unmanned environment is not conducive to air purification, so the ability to purify odors while users are using it can improve the purification efficiency. This equipment can also reduce the risk of cross-infection among toilet users, while effectively and automatically disinfecting and sterilizing the environment.

[0032] It can be explained that in a closed environment, due to factors such as dense crowds and poor air circulation, microorganisms such as bacteria and viruses are easy to breed, resulting in poor air quality and even causing various diseases; the deodorization and sterilization equipment provided in this embodiment is used for disinfection and sterilization, and the disinfection and sterilization time is pre-set according to the temperature, and the time and frequency of disinfection and sterilization are reasonably arranged to ensure the hygiene and safety of the environment; specifically, according to the 24-hour timing, deodorization is carried out from 5 am to 10:30 pm, and disinfection is carried out from 12 pm to the morning location, so as to work in advance and avoid odors in the environment.

[0033] As an optional implementation, the closed deodorizing and sterilizing device 1 is designed to be wall-mounted, which reduces the floor space occupied by the entire box 10 and improves the space utilization rate of the toilet.

[0034] The material of the filter element can be a fiber filter element, wherein the fiber filter element is suitable for filtering particulate matter, and common fiber materials include paper filter elements, cotton cores, etc.

[0035] It is explained that a filter element is arranged at the air inlet 111 of the fan 110, which can first filter pollutants such as dust, bacteria, and particulate matter in the air to keep the air inside the fan 110 clean, thereby improving the working efficiency of the fan 110 and reducing energy consumption; it can also protect the fan 110, prevent pollutants from entering the inside of the fan 110, reduce wear and failure of the fan 110, and extend its service life.

[0036] It can be understood that the design of the box 10 can be used for closed treatment of each environment that requires deodorization and disinfection, that is, the transfer unit 11, the ultraviolet disinfection unit 12, the high-energy ion disinfection unit 13 and the active deodorization unit 14 are designed in a unified manner, and the air entering the closed deodorization and disinfection equipment is disinfected and sterilized by ultraviolet rays in combination with the high-energy ion disinfection unit 13, and then the odor in the air is thoroughly oxidized by the active deodorization unit 14 to restore fresh air, and then discharged back to the original environment to ensure the freshness of the ambient air. This setting can completely change the odor in the environment, and the fresh air restoration can be completed inside the box 10, and there is no need to discharge it into the atmosphere for dilution, thereby not causing new environmental pollution; and the functions of disinfection and sterilization coexist, and there is no need to manually spray disinfectants, which reduces costs, reduces interference from human factors, and reduces the risk of cross-infection among users in the current environment.

[0037] Furthermore, the box body 10 is provided with a louvered air outlet 100 , and the louvered air outlet 100 , the odor treatment passage and the air inlet 111 are designed to be interconnected.

[0038] It is explained that the louver air outlet 100 and the air inlet 111 are interconnected through an odor treatment channel, and the ultraviolet disinfection unit 12, the high-energy ion disinfection unit 13 and the active deodorization unit 14 are arranged in the odor treatment channel in sequence according to the order of odor treatment to realize the circuitous movement of air flow, achieve deodorization and disinfection of each mechanism combination, and improve the air purity after disinfection.

[0039] Furthermore, a filter is provided near the louver air outlet 100 .

[0040] As an optional implementation, the filter element and the air inlet 111, as well as the louvered air outlet 100 and the filter screen, can be detachably connected to facilitate cleaning and replacement, making the use more convenient and practical.

[0041] It is explained that the louver air vent 100 is the air outlet after the air treatment is completed, and the filter is set at the air outlet to filter the odor after the treatment again, so as to improve the purity of the fresh air as much as possible, and during the whole treatment process, it does not need to be discharged into the atmosphere for dilution, so as not to cause secondary pollution to the environment.

[0042] Furthermore, the ultraviolet disinfection unit 12 includes an ultraviolet chip 120 and a reflection plate 121 for reflecting ultraviolet light, and a reflection surface of the reflection plate 121 faces the high-energy ion disinfection unit 13 .

[0043] It is explained that the ultraviolet chip 120 mainly uses far ultraviolet rays for disinfection and sterilization. Among them, far ultraviolet rays are also called C waves or sterilizing ultraviolet rays. The ultraviolet radiation with a wavelength of 200-280nm is mainly used for disinfection and sterilization. The ultraviolet rays with a wavelength of 253-257nm have the best sterilization effect.

[0044] Specifically, air enters the interior of the box 10 through the air inlet 111 of the fan 110, and flows along the odor treatment channel to the ultraviolet disinfection unit 12 for disinfection and sterilization with far ultraviolet rays, and then is transmitted to the high-energy ion disinfection unit 13 through the reflective surface of the reflective plate 121. The position between the reflective plate 121 and the high-energy ion disinfection unit 13 allows the air after disinfection to extend its residence time in the ultraviolet disinfection unit 12 and the high-energy ion disinfection unit 13, so that the air can be fully sterilized and disinfected by ultraviolet rays, thereby ensuring the sterilization effect of the ultraviolet disinfection unit 12.

[0045] Furthermore, the box 10 also includes a control system, which includes a controller and a control panel, and the controller and the control panel are electrically connected.

[0046] It can be explained that the controller can send the received signal to the control panel for display in a timely manner to facilitate monitoring by the staff. The staff can also send commands to the controller through the control options on the control panel to facilitate management and control by the staff. This setting helps the staff to grasp the operating status of the deodorization and disinfection equipment 1 in each closed environment at any time.

[0047] Furthermore, the high-energy ion disinfection unit 13 is an ion generating device. When the controller, the ion generating device and the ultraviolet disinfection unit 12 cooperate with each other to operate, the ion concentration in the odor treatment channel reaches or exceeds a first preset level.

[0048] It is explained that the ionization generating device is used to carry out the air ionization process. The first preset level means that if the ion concentration in nature is 800 / cubic centimeter, of which 400 are positive ions and 400 are negative ions; it can be explained that the use of electric ion technology can artificially realize the efficient and harmless ionization process of self-purification of natural air, and maintain the ion life of about 2.5 hours and control the ion concentration as needed, so as to produce positive and negative ions similar to those in nature, so as to achieve the purpose of purifying indoor polluted air, and can make the indoor air reach the level of park air quality.

[0049] Furthermore, the ion generating device forms an ion curtain in the odor treatment channel, and the ions of the ion curtain include any one of photohydrogen ions, photoplasma and negative oxygen ions.

[0050] It is explained that any type of ion in the ion curtain processes the air in the odor treatment channel, among which photohydrogen ions are hydrogen ions generated by photoionization, have higher energy, can react with organic matter in the odor, decompose organic molecules, and thus remove the source of odor; photoplasma is a charged particle generated by photoionization, has higher energy and activity, can undergo oxidation reaction with organic molecules in the odor, oxidize the organic matter into harmless substances, and thus eliminate odor; negative oxygen ions are oxygen molecules or oxygen ions with negative charge, have strong chemical activity, can react with organic matter, bacteria, viruses, etc. in the odor, oxidize, decompose or kill these harmful substances, and thus improve air quality; specifically, by generating an ion curtain, ions can react with organic matter or harmful substances in the odor, thereby purifying the air and removing odor, which can effectively improve air quality and provide a fresher and healthier environment.

[0051] Specifically, when the controller, the ion generator and the ultraviolet disinfection unit 12 cooperate with each other to operate, the ion concentration in the odor treatment channel reaches or exceeds the first preset level, and the air disinfected by the ultraviolet disinfection unit is transmitted to the ion generator, that is, the bipolar high-energy ions generated in the far ultraviolet light and the ion generator are used to disinfect and sterilize the air entering the box 10, wherein the bipolar high-energy ions are generated by the far ultraviolet light and the strong electric field, and the strong electric field can produce an ionization effect, decomposing the oxygen molecules in the air into oxygen ions and free electrons. These charged particles have higher energy and can produce The far-ultraviolet light and strong electric field technology can induce ionization to further enhance the sterilization effect. Therefore, the bipolar high-energy ions generated by the far-ultraviolet light and the strong electric field are used to disinfect and sterilize the air entering the equipment. It can effectively sterilize the microorganisms in the air, including bacteria, viruses, fungi, etc., and reduce the risk of transmission of pathogens in the air and cross-infection. The sterilization effect is more lasting, which can eliminate microorganisms in the air and prevent them from multiplying again, keeping the air clean and hygienic. Moreover, the far-ultraviolet light and strong electric field technology does not require the use of chemical agents, is pollution-free to the environment, harmless to the human body, and can effectively protect the air quality and reduce the spread of pathogens.

[0052] Furthermore, the active deodorizing unit 14 includes a water tank 141 and an atomizer 142 , and the atomizer 142 is electrically connected to the controller.

[0053] It is explained that the active deodorization unit 14 utilizes a high-intensity electric field and water to produce active water with strong oxidizing properties, that is, in this way, active water mist with strong oxidizing properties is produced to remove odors and harmful gases in the air; wherein, the strong electric field ionizes the oxygen molecules in the air to generate active oxygen, which can react with the odors and harmful gases in the air, and then the water mist produced by the cooperation of the water tank 141 and the atomizer 142 is mixed with the active oxygen to adsorb or decompose the odors and harmful gases; and the control system can more easily control the operation of the active deodorization unit 14, so that the active deodorization unit 14 can effectively remove odors in the air and improve the indoor air quality.

[0054] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
