EMBODIMENTS

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0017] Please refer to Figures 1-4 , this embodiment provides an air disinfection machine, including a housing 1, and an automatic walking base 2 is provided at the bottom of the housing 1. Among them, the automatic walking base 2 is a prior art and can be obtained by custom purchase, so it will not be described in detail. A spray hood 8 is provided at the top of the housing 1, and a plurality of atomizing nozzles 9 with changeable spray directions are evenly arranged on the spray hood 8. Specifically, as Figure 1 and Figure 2 shown, a plurality of fish-eye bearings 17 are evenly arranged on the spray hood 8. The atomizing nozzle 9 passes through the fish-eye bearing 17 and is fixedly connected to the fish-eye bearing 17. The tail of the atomizing nozzle 9 is connected to a solenoid valve 18. The input end of the solenoid valve 18 is connected to a hose 10, and the hose 10 is connected to a shunt head 11. The shunt head 11 is arranged in the spray hood 8 and fixed to the top of the housing 1. As Figure 3 shown, the shape of the shunt head 11 corresponds to that of the spray hood 8, both are hemispherical. A shunt main port 13 connected to the liquid supply assembly is provided at the bottom of the shunt head 11. A plurality of shunt cavities 12 are evenly opened in the shunt head 11. Both ends of the shunt cavity 12 are respectively connected to the shunt main port 13 and the hose 10, and are used to evenly shunt the disinfectant liquid output by the liquid supply assembly to each atomizing nozzle 9. A connection seat 19 sleeved on the periphery of the hose 10 is fixedly provided at the bottom of the solenoid valve 18. A plurality of variable-direction electric telescopic rods 16 are evenly hinged on the connection seat 19. The upper ends of the variable-direction electric telescopic rods 16 are hinged to the inner wall of the spray hood 8. By controlling the expansion and contraction of the variable-direction electric telescopic rods 16, the atomizing nozzle 9 is driven to rotate.

[0018] The liquid supply assembly is arranged in the housing 1, and it includes a liquid storage tank 3 arranged in the housing 1. A liquid pump 4 is arranged in the liquid storage tank 3. The liquid pump 4 is connected to the shunt main port 13 through a liquid pipe 5. In order to achieve better liquid output, a pressurizing fan 14 is provided at the top of the liquid storage tank 3. The pressurizing fan 14 can be obtained by direct purchase, and its air outlet is communicated with the inside of the liquid storage tank 3. A liquid level gauge 15 connected to the liquid storage tank 3 is also provided on the outside of the housing 1, which is convenient for observing the content of the disinfectant liquid in the liquid outlet tank 3.

[0019] In order to better monitor the disinfectant concentration in the environment, a disinfectant concentration detector 7 is provided on the housing 1. According to the chemical disinfection method, this detector is preferably a peracetic acid concentration detector assembled by direct purchase, and the technology is mature and will not be described in detail.

[0020] In addition, in practical applications, as a conventional setting familiar to those skilled in the art, a liquid injection port 6 corresponding to the liquid storage tank 3 needs to be provided on the outer shell 1 for timely replenishment of the disinfectant. At the same time, as Figure 4 shown, a main controller 20 also needs to be provided on the outer shell 1, which is electrically connected to the self-propelled base 2, the disinfectant concentration detector 7, the pressure blower 14, the variable-direction electric telescopic rod 16, and the electromagnetic valve 18 for regulating the operation of the disinfection machine. The control program can be set by coding at the factory, which is a conventional design for those skilled in the art and will not be elaborated in this application.

[0021] To enable those skilled in the art to better understand this application, the working principle of this air disinfection machine will be described below: This air disinfection machine is put into large public places such as banks and shopping malls for use when there is no one in the store at night. The self-propelled base 2 has the same working principle as an existing self-propelled vehicle and is obtained by customized purchase to drive the disinfection machine to move forward automatically. Under the regulation of the main controller 20, the liquid pump 4 operates to pump the disinfectant liquid into the flow splitter 11 through the liquid pipe 5. The disinfectant liquid is split by the flow splitter 11 and enters each atomizing nozzle 9. The atomizing nozzle 9 atomizes the disinfectant liquid and sprays it out. At the same time, the variable-direction electric telescopic rod 16 alternately extends and retracts, and with the cooperation of the fisheye bearing 17, the atomizing nozzle 9 swings to achieve omnidirectional spray disinfection. At the same time, the disinfectant concentration detector 7 can also detect the concentration of the disinfectant liquid in the air. It can correspondingly only open a part of the electromagnetic valves 18 to make some atomizing nozzles 9 spray to achieve local disinfection. It can also control the electromagnetic valves 18 to alternately open and close in a cycle through the main controller 20, and the single atomizing nozzle 9 sprays alternately to extend the spraying time and make the spraying more uniform. This control can be obtained by coding, which is a conventional setting and will not be elaborated.

[0022] It should be noted that the above embodiments only specifically and clearly describe the technical solutions and technical features of this application. For those skilled in the art, the solutions or features that belong to the prior art or common general knowledge are not described in detail in the above embodiments.

[0023] In addition, the technical solution of this application is not limited to the above embodiments. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
