[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] This invention discloses a robotic sterilization machine, such as... Figure 1 and Figure 2 As shown, the system includes: a disinfection mechanism 1 and a robotic mechanism 2 for intelligent control of the disinfection components. The disinfection mechanism 1 includes a blower assembly 11 for providing air pressure, a first assembly 12 for providing hydrogen peroxide, and a second assembly 13 for providing ozone. The first assembly 12 includes a material box 121 disposed on the blower assembly 11 for containing hydrogen peroxide. The material box 121 has three outlets 122, and each outlet 122 has an outlet pipe 123 for facilitating the passage of hydrogen peroxide. One end of the blower assembly 11 has three air outlets 1141. A first air outlet pipe 14 is connected to each air outlet 1141. One end of the first air outlet pipe 14 is fixedly connected to a first fixing member 15. The first fixing member 15 is connected to the outlet pipe 123. The system includes a reaction tube 16, which houses an ultraviolet lamp 161 for decomposing hydrogen peroxide. Inside the reaction tube 16 is a mounting bracket 162 for securing the ultraviolet lamp 161. The mounting bracket 162 is snap-fitted into the reaction tube 16. At the other end of the reaction tube 16 is a second fixing member 17, which is also snap-fitted into the reaction tube 16. The second fixing member 17 has three second air outlet pipes 18. The second assembly 13 includes three gas pipes 131 connected to the side wall of the second fixing member 17. The other end of each gas pipe 131 is connected to an ozone generator 132 for generating ozone. The other end of each second air outlet pipe 18 is a reaction hood 19 for providing a gas reaction environment. The side wall of the reaction hood 19 has an outlet 191 to facilitate the passage of hydroxyl radicals generated during the gas reaction. In this implementation, the ultraviolet wavelength of the ultraviolet lamp 161 is 254 nm. The ultraviolet lamp 161 is positioned in the center of the reaction tube 16, with a distance of 5 cm or less from the tube wall. This allows the hydrogen peroxide to be fully decomposed by UVC ultraviolet light, maximizing the generation of hydroxyl radicals. Both the discharge pipe 123 and the gas pipe 131 are flexible tubes. Alternatively, they can be made of shaped stainless steel, with the interior treated with an anti-corrosion material.

[0026] It should be noted that the blower assembly 11 provides air pressure to draw hydrogen peroxide from the material box 121 into the reaction tube 16, where it is decomposed by irradiation through the ultraviolet lamp tube 161. Ozone is generated by the ozone generator 132. Through the blowing action of the blower assembly 11, the mixed gas after decomposition of hydrogen peroxide and ozone are blown into the reaction hood 19 for reaction, releasing hydroxyl radicals for disinfection. The process is intelligently controlled by the robot mechanism 2, thereby enhancing the air disinfection performance and improving intelligence.

[0027] In the specific implementation process, the discharge port 122 and the air outlet 1141 correspond one-to-one, and there can be multiple discharge ports 122 and air outlets 1141, which can be increased or decreased according to the actual disinfection requirements. Multiple air outlets 191 are provided and are circumferentially distributed at equal intervals to facilitate the 360-degree discharge of generated hydroxyl radicals through the reaction hood 19.

[0028] like Figure 1 and Figure 2 As shown, the blower assembly 11 includes a blower base plate 111 connected to the robot mechanism 2, an air intake hood 112 on the blower base plate 111 for facilitating air passage, a fan 113 fixedly mounted on the air intake hood 112, and a buffer cover 114 on the air intake hood 112 for buffering the air pressure generated by the fan 113. The buffer cover 114 is detachably connected to the air intake hood 112.

[0029] like Figure 1 and Figure 2 As shown, the side of the air intake shroud 112 is provided with several air intake holes 1121 at equal intervals.

[0030] like Figure 1 and Figure 2 As shown, the material box 121 is provided with a feed port for convenient injection of hydrogen peroxide, and the feed port is provided with a threaded sealing cap 124. In actual implementation, the sealing cap 124 adopts an electronic lock, and the consumable is marked with a unique identification number. The user needs to enter the unique identification number on a monitor, mobile terminal, or other mobile terminal before the sealing cap 124 can be opened to replace the consumable.

[0031] like Figure 1 and Figure 2 As shown, the discharge port 122 is equipped with a suction rod for conveniently sucking out hydrogen peroxide from the material box 121.

[0032] like Figure 1 and Figure 2 As shown, a UVA ultraviolet lamp is installed inside the reaction chamber 19, and the inner wall of the reaction chamber 19 is coated with titanium dioxide. The following reaction is produced:

[0033] UVC + O3 = O2 + O·

[0034] UVC + H₂O₂ = 2HO·

[0035] OH· + OH· = H2O2

[0036] UVA + TiO2 = 2OH· (under humid conditions)

[0037] UVA + TiO2 + O2 = H2O2

[0038] UVA + TiO2 + H2O = H2O2

[0039] like Figure 1 and Figure 2 As shown, the robot mechanism 2 includes a robot body 21 fixedly connected to the blower assembly 11. The bottom of the robot body 21 is provided with driving wheels 22 for moving the robot body 21, and the bottom of the robot body 21 is provided with a robot motor 23 for driving the driving wheels 22 to move.

[0040] like Figure 1 and Figure 2 As shown, the bottom of the robot body 21 is equipped with casters 24 for easy movement of the robot body 21. The casters 24 are omnidirectional wheels. It should be noted that the disinfection robot can expand the disinfection range; the 360-degree air vents can enhance the disinfection effect.

[0041] like Figure 1 and Figure 2 As shown, a liquid level sensor for detecting the hydrogen peroxide volume inside the material box 121 is provided on the outer wall of the material box 121. The external sensor is not subject to liquid corrosion, which facilitates the design of the product shape and is not limited by the structure.

[0042] like Figure 1 and Figure 2 As shown, the diameters of the first air outlet pipe 14, the reaction pipe 16, and the second air outlet pipe 18 gradually increase in sequence.

[0043] In practical implementation, this invention uses Bluetooth, WIFI or 4G modules to transmit information on disinfection status, consumable replacement status, air quality, and control of disinfection equipment via APP or WeChat mini program or other Internet modes to achieve human-computer interaction, making it convenient for customers to use.

[0044] Working principle: The blower assembly 11 provides air pressure to draw hydrogen peroxide from the material box 121 into the reaction tube 16, where it is decomposed by irradiation through the ultraviolet lamp tube 161. Ozone is generated by the ozone generator 132. Through the blowing action of the blower assembly 11, the mixed gas after decomposition of hydrogen peroxide and ozone are blown into the reaction hood 19 for reaction, releasing hydroxyl radicals for disinfection. The system is intelligently controlled by the robot mechanism 2, thereby enhancing the air disinfection performance and improving intelligence.

[0045] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
