Description

Technical Field

[0001] This application relates to the field of disinfection equipment technology, and in particular to a portable ultraviolet ozone dual-effect disinfection machine. Background Technology

[0002] While ultraviolet (UV) disinfection is effective at killing some bacteria and viruses, its effectiveness is greatly affected by the angle and distance of irradiation, making it difficult to achieve complete coverage for irregularly shaped or differently sized items. Ozone disinfection, with its strong oxidizing properties and wide disinfection range, is less effective when used alone in certain scenarios, and ozone leakage can irritate the respiratory tract. Furthermore, most existing disinfection devices are bulky and have limited functionality, failing to meet the needs for convenient and efficient disinfection in various scenarios, such as travel and office work. A compact, portable device capable of combining multiple disinfection methods is needed. It is against this backdrop that the portable UV-ozone dual-effect disinfection machine has emerged, aiming to overcome the shortcomings of traditional disinfection methods and provide users with a higher-quality, more comprehensive, and convenient disinfection experience.

[0003] A search revealed Chinese Patent Publication No. CN203555980U, which discloses an ultraviolet sterilization and disinfection device. The device includes a housing, a sterilization and disinfection unit, an electrical device, and an airflow circulation device located within the housing. The sterilization and disinfection unit comprises a sterilization and disinfection module, which is a detachable, embedded structure. Each sterilization and disinfection module includes at least one detachable, embedded ultraviolet module. The detachable, embedded ultraviolet module includes one or more ultraviolet light sources, which are connected to the electrical device to obtain power. This invention simplifies the assembly and maintenance of the ultraviolet sterilization and disinfection device, allows for the design of devices with different functions within the same housing, reduces the design and development costs of the housing, and enables adjustments to the sterilization and disinfection performance according to the application requirements.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: the devices only possess a single ultraviolet disinfection function, resulting in a limited disinfection method. When faced with a diverse array of bacteria, viruses, and other microorganisms, they cannot guarantee comprehensive and efficient disinfection. Furthermore, they lack portability, failing to meet people's needs for disinfection anytime, anywhere. Utility Model Content

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a portable ultraviolet ozone dual-effect disinfection machine.

[0035] Please see Figure 1 A portable ultraviolet ozone dual-effect disinfection machine includes a disinfection machine base 1, an ozone disinfection component 2 is installed inside the disinfection machine base 1, and an ultraviolet disinfection component 3 is installed on its top.

[0036] Please see Figures 2 to 4The ultraviolet disinfection component 3 includes a servo motor 301, a lead screw 302, a bearing top bracket 303, a housing 304, an internally threaded lifting plate 305, a slot 306, a transparent protective cover 307, an ultraviolet lamp 308, and a limiting rod 311. The servo motor 301 is fixed to the top of the ozone disinfection component 2, and its output end is connected to the lead screw 302. The top of the lead screw 302 is movably connected to the bearing top bracket 303. The housing 304 is fixed to one side of the bearing top bracket 303, and a limiting rod 311 is provided inside it. The internally threaded lifting plate 305 slides with the limiting rod 311 through the slot 306 and is threaded onto the side of the lead screw 302. The transparent protective cover 307 is fixed to the top of the internally threaded lifting plate 305, and an ultraviolet lamp 308 is installed inside it. A ballast is provided at the bottom of the ultraviolet lamp 308.

[0037] The ultraviolet disinfection component 3 also includes air outlets 309 symmetrically opened on both sides of the housing 304, and a limiting ring 310 fixed to the top of the housing 304. The limiting ring 310 is used to limit the upward stroke of the internal thread lifting plate 305.

[0038] The ozone disinfection assembly 2 includes a filter element 201, an extraction pipe 202, an air pump 203, an ozone generator 204, a sealing partition 205, and a one-way valve 206. The filter element 201 is installed on the side of the disinfection machine base 1 and is connected to the extraction pipe 202, the air pump 203, and the ozone generator 204 in sequence. The sealing partition 205 is fixed between the disinfection machine base 1 and the outer shell 304, and a one-way valve 206 is installed in the opening at the top of the partition. The one-way valve 206 only allows gas from the disinfection machine base 1 to flow into the outer shell 304.

[0039] The air pump 203 is sealed to the ozone generator 204 via a hose, and the air inlet of the air pump 203 is equipped with an anti-backflow structure.

[0040] The transparent protective cover 307 is made of high-transmittance quartz glass, and its outer surface is coated with an explosion-proof film.

[0041] The base 1 of the disinfection machine is also equipped with a control module, which is electrically connected to the servo motor 301, the ultraviolet lamp 308 and the ozone generator 204 respectively, and is used to coordinate the start and stop sequence of ultraviolet and ozone disinfection modes.

[0042] The base of the sterilizer 1 has a rechargeable battery pack embedded in its bottom, and its side wall has a USB-C charging port and a mode switching button.

[0043] The sealing partition 205 divides the interior of the sterilizer base 1 into an air pump 203 chamber and an ozone reaction chamber, and the one-way valve 206 is a duckbill-shaped one-way valve, which is installed at an angle in the hole of the sealing partition 205.

[0044] The ultraviolet lamps 308 are arranged in a ring array, and their ballasts are fixed in the bottom groove of the internal threaded lifting plate 305 through a waterproof connector.

[0045] Further explanation is needed: The primary function of the UV disinfection component 3 is to provide efficient UV disinfection. The servo motor 301, lead screw 302, and internally threaded lifting plate 305 work together. When the servo motor 301 starts, its output drives the lead screw 302 to rotate. Since the lead screw 302 and the internally threaded lifting plate 305 are threadedly connected, the rotation of the lead screw 302 is converted into the vertical linear motion of the internally threaded lifting plate 305. The UV lamp 308, fixed to the top of the internally threaded lifting plate 305, can then flexibly adjust its height. This design allows the disinfection machine to precisely position the UV lamp 308 according to the height of the items to be disinfected, providing comprehensive UV disinfection of items of different heights without blind spots. This greatly improves the flexibility and applicability of disinfection, enabling efficient disinfection of both large and small items.

[0046] Meanwhile, the ultraviolet disinfection component 3 also has the function of protecting and ensuring the efficient transmission of ultraviolet rays. The housing 304 has a limiting rod 311 inside. The internal threaded lifting plate 305 slides with the limiting rod 311 through the slot 306 to ensure the stability of the lifting process. The transparent protective cover 307 fixed on the top of the internal threaded lifting plate 305 is made of high light transmittance quartz glass and coated with an explosion-proof film layer on the outer surface. It can protect the internal ultraviolet lamp 308 from collision damage and ensure that the ultraviolet rays penetrate with the highest efficiency to reliably disinfect the items. The air outlets 309 on both sides are conducive to gas circulation. The limiting ring 310 on the top precisely limits the upward stroke of the internal threaded lifting plate 305, ensuring the safety and stability of the entire component operation.

[0047] The implementation principle of a portable ultraviolet ozone dual-effect disinfection machine according to an embodiment of this application is as follows:

[0048] First, when the equipment is turned on, the control module located inside the disinfection machine base 1 starts. Then, the ozone disinfection component 2 starts working. The filter element 201 installed on the side of the disinfection machine base 1 first filters the outside air to remove impurities. The filtered air passes through the air extraction pipe 202 and is then transported to the ozone generator 204 by the air pump 203. Ozone is generated in the ozone generator 204 to perform preliminary disinfection of the space where the equipment is located.

[0049] Secondly, the servo motor 301 in the ultraviolet disinfection component 3 is started. The output end of the servo motor 301 drives the lead screw 302 to rotate. Since the lead screw 302 is threadedly connected to the internal thread lifting plate 305, the rotational motion of the lead screw 302 is converted into the vertical linear motion of the internal thread lifting plate 305. This is used to adjust the height of the ultraviolet lamp 308 fixed on the top of the internal thread lifting plate 305 to accommodate items to be disinfected at different heights.

[0050] Next, once the UV lamp 308 is adjusted to the appropriate height, it begins to emit UV light. The ballast fixed at the bottom of the UV lamp 308 ensures stable light emission. Meanwhile, the transparent protective cover 307 not only protects the UV lamp 308, but also, because it is made of high-transmittance quartz glass, ensures that the UV light can penetrate efficiently to disinfect items.

[0051] Next, during the operation of the UV disinfection component 3, the internal thread lifting plate 305 slides with the limiting rod 311 inside the housing 304 through the slot 306 to ensure the stability of the lifting process. In addition, the limiting ring 310 at the top of the housing 304 restricts the upward stroke of the internal thread lifting plate 305 to prevent it from rising excessively and ensure the safe operation of the equipment.

[0052] Finally, the ozone generated by the ozone disinfection component 2 flows into the outer shell 304 through the one-way valve 206 in the top opening of the sealed partition 205, and works in conjunction with the ultraviolet disinfection to achieve dual-effect ultraviolet and ozone disinfection, killing bacteria, viruses and other microorganisms in all directions, and completing the efficient disinfection of items.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
