[0002] Fresh air sterilizers, as key equipment for improving indoor air quality, have been widely used in some enclosed spaces such as hospitals, schools, office buildings, offices, and bank lobbies. Their core function is to continuously provide clean, fresh air to the room through filtration and sterilization. During the operation of the equipment, the filters installed at the air inlet and outlet bear the heavy responsibility of intercepting pollutants such as dust, particulate matter, and some microorganisms. With the accumulation of use time, these filters will gradually become clogged and saturated, leading to a decrease in equipment efficiency, reduced air volume, increased energy consumption, and may even become a source of secondary pollution. Therefore, regularly disassembling, cleaning, or replacing these filters is an essential maintenance step to ensure the efficient and safe operation of fresh air sterilizers. However, most existing wall-mounted fresh air sterilizers require individual installation and fixing of the air inlet and outlet filters during maintenance. Maintenance personnel need to operate on each filter sequentially, and the installation and removal process often relies on specific tools to tighten or loosen them. This design makes the maintenance process cumbersome and time-consuming, placing an additional burden on users or maintenance personnel and increasing the complexity and time cost of maintenance. This problem is particularly prominent for wall-mounted models installed at higher positions. Therefore, this utility model provides a wall-mounted fresh air sterilizer that is easy to install.

[0014] The present invention will be further described below with reference to the embodiments.
[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.
[0016] Please see Figures 1-6 This utility model provides a wall-mounted fresh air disinfection machine that is easy to install, including a fresh air disinfection machine body 1. A control panel 101 is fixedly connected to the top of the front of the fresh air disinfection machine body 1. A connecting frame 2 is snapped into the bottom of the front of the fresh air disinfection machine body 1. A screen is provided inside the connecting frame 2. A docking part adapted to the connecting frame 2 is opened on the front of the fresh air disinfection machine body 1. Two docking grooves 106 are opened on both sides of the docking part facing outward. Four fixing parts 203 adapted to the docking grooves 106 are symmetrically arranged on both sides of the connecting frame 2. A limiting protrusion 1062 is provided inside each docking groove 106. A limiting groove 2032 adapted to the limiting protrusion 1062 is provided on the side of the fixing part 203 facing the limiting protrusion 1062. An auxiliary cavity 2031 is provided on the outer side of the fixing part 203. One side is provided with a guide slope 2033. The inside of the connecting frame 2 is provided with a planar cavity 2001 and an inclined cavity 2002. The first screen 201 and the second screen 202 are respectively installed inside the planar cavity 2001 and the inclined cavity 2002. The front of the docking part is provided with an air inlet frame 107 and an exhaust frame 108 aligned with the first screen 201 and the second screen 202. Both sides of the inner cavity of the planar cavity 2001 and the inclined cavity 2002 are provided with multiple fastening protrusions 204. Both ends of each screen are provided with fastening grooves 205. One side of the docking part is provided with an air intake pump 3 connected to the air intake frame 107. One side of the air intake pump 3 is provided with a disinfection box 4. One side of the disinfection box 4 is provided with a purification box 5. One side of the purification box 5 is provided with a sterilization box 6. The output end of the sterilization box 6 is fixedly connected to the exhaust frame 108. The various boxes are fixedly connected to each other through a conduit. Place the main body 1 of the fresh air disinfection machine stably in a suitable position, and prepare the connecting frame 2, the first screen 201, the second screen 202 and other components, ensuring that each component is intact and free of impurities; Insert the first screen 201 into the flat cavity 2001 of the connecting frame 2, so that the fastening grooves 205 at both ends of the screen fit tightly with the fastening protrusions 204 on both sides of the inner cavity of the flat cavity 2001; similarly, insert the second screen 202 into the inclined cavity 2002 to ensure a stable connection. Hold the connecting frame 2 and align the guide slopes 2033 on the fixing parts 203 on both sides with the docking grooves 106 on both sides of the docking part of the main body 1 of the fresh air disinfection machine. Slowly push the connecting frame 2 into the docking part. Under the action of the guide slopes 2033, the fixing parts 203 smoothly enter the docking grooves 106. As the connecting frame 2 goes deeper, the limiting protrusions 1062 inside the docking grooves 106 will be embedded in the limiting grooves 2032 on the fixing parts 203. At the same time, the auxiliary cavity 2031 can provide a certain amount of buffering and adjustment space to ensure that the connecting frame 2 and the docking part are tightly and accurately connected together. Start the air intake pump 3. Under the action of the air intake pump 3, outside air is drawn into the fresh air disinfection machine through the air intake frame 107. At this time, the first screen 201 performs preliminary filtration on the air intake, intercepting larger particles of dust, debris, etc., to prevent them from entering the subsequent processing stage, protecting the internal components of the equipment and improving the subsequent processing effect. The air, after initial filtration, enters the disinfection chamber 4 through a duct. The disinfection chamber 4 is equipped with a specific disinfection device (such as an existing ozone generator) to kill and disinfect microorganisms such as bacteria and viruses in the air, effectively reducing the content of pathogens in the air and ensuring the hygiene and safety of the air. After disinfection, the air flows into the purification box 5, which is filled with highly efficient purification materials (such as activated carbon) that can adsorb harmful gases (such as formaldehyde and benzene volatile organic compounds), odors and fine particulate matter in the air, further purifying the air and improving air quality. The purified air enters sterilization chamber 6, which uses a germicidal lamp to perform deep sterilization treatment on the air, completely eliminating residual bacteria, viruses and other microorganisms in the air, and ensuring that the output air meets a high level of cleanliness. After sterilization, the clean air is delivered to the discharge rack 108 through a duct, and then discharged into the room through the second screen 202, providing fresh, clean and healthy air to the room; The connecting frame 2 and the main body 1 of the fresh air disinfection machine are quickly connected through the cooperation of the fixing part 203 and the docking groove 106. The design of the limiting protrusion 1062 and the limiting groove 2032 ensures the accuracy and stability of the connection. There is no need to use complicated tools and cumbersome operation steps, which greatly shortens the installation time and reduces the installation difficulty. Even ordinary users can easily complete the installation. The fastening protrusions 204 on both sides of the inner cavity of the planar cavity 2001 and the inclined cavity 2002 cooperate with the fastening grooves 205 at both ends of the screen, making the installation and disassembly of the first screen 201 and the second screen 202 very convenient. The design of the planar cavity 2001 and the inclined cavity 2002 inside the connecting frame 2 results in a certain angle between the air inlet and the air outlet, effectively preventing the fresh air from being immediately re-entered into the device for disinfection. This not only improves the air treatment efficiency but also prevents the mixing of treated air with untreated air, avoids secondary pollution, and ensures a stable improvement in indoor air quality.
[0017] In this embodiment, two wall hooks 103 are symmetrically fixedly connected to the back of the main body 1 of the fresh air disinfection machine. The wall hooks 103 have connecting holes 104 inside, and the top of the inner cavity of the connecting holes 104 has a locking part 105. Before installing the wall-mounted fresh air disinfection machine, it is necessary to determine a suitable installation position. Use a level to determine two installation points on the selected wall surface that correspond to the positions of the wall hooks 103, and ensure that the two installation points are on the same horizontal line to ensure that the fresh air disinfection machine is horizontally stable after installation. According to the size of the expansion screws, use an electric drill to drill holes of appropriate depth and diameter on the wall surface. During the drilling process, pay attention to keeping the electric drill vertical to avoid tilting the holes and affecting the installation effect. Insert the expansion screws one by one into the drilled holes, and use a screwdriver or special tool to tighten the expansion screws so that the expansion screws expand and fix in the wall, providing a stable support for subsequent installation. Ensure that both expansion screws are installed firmly and without loosening. The staff then lifts the main body 1 of the fresh air sterilizer, aligning the two wall hooks 103 on the back with the two expansion screws on the wall. They then slowly lower the main body 1, allowing the heads of the expansion screws to enter the connection holes 104 of the wall hooks 103. During placement, the staff should adjust the position of the main body 1 to ensure it fits snugly against the wall. Simultaneously, the staff should allow the heads of the expansion screws to slide smoothly into the locking part 105 at the top of the inner cavity of the connection hole 104. When a "click" is heard or the main body 1 feels clearly in place, it indicates that the heads of the expansion screws have engaged with the locking part 105, and the main body 1 is now properly installed.
[0018] The working principle and usage process of this utility model are as follows: First, install the wall-mounted fresh air disinfection machine. First, determine a suitable installation location. Use a level to mark two installation points on the wall that correspond to the wall hook 103 and ensure that they are level. Drill suitable holes according to the size of the expansion screws. Keep the electric drill vertical and insert the expansion screws and tighten them to ensure that they are secure and not loose. Two people lift the main body 1 of the fresh air disinfection machine and align the wall hook 103 with the expansion screws. Slowly lower it so that it enters the connection hole 104 and slides into the locking part 105. When you hear a "click" or feel that it is in place, the installation is complete. Prepare intact and impurity-free components such as connecting frame 2, first screen 201, and second screen 202. Insert the first screen 201 into the plane cavity 2001 of connecting frame 2 and the second screen 202 into the inclined cavity 2002 to ensure a stable connection. Hold connecting frame 2 and guide the inclined surface 203 of the fixing part 203 to align with the docking groove 106. Slowly push it in, and the limiting protrusion 1062 will be embedded into the limiting groove 2032 for a tight and accurate connection. When the air intake pump 3 is started, outside air is drawn in through the air intake frame 107. The first screen 201 initially filters out large particles of dust and debris. The air enters the disinfection box 4 through the duct and is disinfected and sterilized by the ozone generator. After disinfection, it flows into the purification box 5, where activated carbon adsorbs harmful gases, odors and fine particles. Then it enters the sterilization box 6, where it is deeply sterilized by photocatalysis. Finally, the clean air is discharged into the room through the exhaust frame 108 through the duct and passes through the second screen 202.
[0019] It should be noted in the above scheme that the circuit connection of the air pump 3, disinfection box 4, purification box 5 and sterilization box 6 is laid out and installed in accordance with conventional electrical connection specifications. The components are connected in series with appropriate wires to ensure that the power can be transmitted to each device stably and safely, and to ensure its normal operation. At the same time, in order to prevent safety hazards such as short circuits and overloads, corresponding protection devices such as fuses and circuit breakers are installed in the circuit. When the circuit is abnormal, these protection devices can cut off the power supply in time to avoid equipment damage or even serious consequences such as fire. Meanwhile, the ozone generator inside the disinfection box 4, the activated carbon filled in the purification box 5, and the photocatalytic sterilization device used in the sterilization box 6 are all existing publicly available technologies. These disinfection tools are widely used in the market and are technically mature and reliable. The ozone generator can produce ozone with strong oxidizing properties, which can effectively kill bacteria, viruses and other microorganisms in the air. Activated carbon, with its porous structure, has a strong adsorption capacity and can adsorb harmful gases and odors in the air. The germicidal lamp kills bacteria. Since these technologies are well known to the public and have undergone a lot of verification and improvement in practical applications, they are not described in detail in this solution.
