A buckle plate 109 is arranged at the lower part of the spring cap 104, and the buckle plate 109 abuts against the side wall of the fixing groove 101. An extension plate 107 is arranged on one side of the buckle plate 109. The extension plate 107 is located at the upper part of the mounting groove to limit the moving path of the spring cap 104 compressing the first return spring 106 to prevent the spring cap 104 from falling into the fixing groove 101.

[0047] In this embodiment, a movable groove is provided on one side of the spring cap 104, and movable end positioning columns 105 are provided on both sides of the bottom wall in the movable groove. The movable end positioning column 105 is buckled with the first return spring 106, and the first return spring 106 is in a compressed state and is located between the movable end positioning column 105 and the fixed end positioning column 1010. Limiting columns 1011 are provided on both side ends of the extension plate 107, and the limiting columns 1011 are adapted to the limiting groove 1012 provided on the connecting seat 102. By utilizing the cooperation between the limiting groove 1012 and the limiting column 1011, the horizontal movement of the spring cap 104 on the connecting seat 102 is realized, and the extension plate 107 is fitted into the notch of the fixed groove 101 to prevent the spring cap 104 from falling downward into the fixed groove 101, and the buckle plate 109 is fixed to the inner wall of the fixed groove 101 when the external force is removed.

[0048] In this embodiment, buckle cap grooves 1013 are provided on both side walls of the lower part of the ozone disinfection module 7, and the buckle cap grooves 1013 are buckled with the elastic cap 104. External force presses the elastic cap 104 to separate the buckle cap grooves 1013 from the elastic cap. At this time, the ozone disinfection module 7 and the secondary filter element module 6 can be separated and disassembled.

[0049] In this embodiment, a sterilization device 1014 is provided in the ozone disinfection module 7, and the sterilization device 1014 includes an ozone generator. The ozone generator acts on the air flow box in the ozone disinfection module 4 to complete sterilization and disinfection. After completing the sterilization and disinfection, the air in the air flow box does not flow out of the body through the air outlet hood 8.

[0050] In this embodiment, the knob fixing structure 11 includes a bottom plate 111 arranged at the bottom of the fan module 4, the first-stage filter element module 5, the second-stage filter element module 6, and the preliminary filter module 1, and a fixing cylinder 112 is extended upward on all four sides of the top of the bottom plate 111, and a connecting column 113 is arranged in the fixing cylinder 112. The lower part of the connecting column 113 extends downward to the outside of the fixing cylinder 112, and a slot 116 is arranged at the upper part of the connecting column 113, and a plug column 115 is arranged in the slot 116. One end of the plug column 115 is connected to a fixing rod 114, and the fixing rod 114 passes through the upper wall of the fixing cylinder 112, and the end is connected to a knob seat 118, and the knob seat 118 is arranged in a connecting sleeve 119. The connecting sleeve 119 has fixing parts 1110 on all four sides, and the fixing parts 1110 are fixed to the matching grooves on the tops of the fan module 4, the first-stage filter element module 5, the second-stage filter element module 6, and the preliminary filter module 1.

[0051] In this embodiment, the cross-section of the plug post 115 is rectangular and is inserted into the rectangular slot 116. When the fixing rod 114 subsequently drives the connecting column 113 to rotate, the rectangular plug post 115 and the slot 116 will not slide relative to each other, thereby achieving synchronous rotation of the knob seat 118 and the connecting column 113.

[0052] In this embodiment, a second return spring 1111 is sleeved on the outer wall of the fixing rod 114 between the knob seat 118 and the fixing tube 112. The second return spring 1111 is in a compressed state, and a positioning screw hole 117 is provided at the lower part of the connecting column 113. A connecting screw 15 is provided in the positioning screw hole 117. The connecting screw 15 connects and fixes the connecting column 113 with the fixing hole at the bottom of the plug column 115. In this way, the second return spring 1111 is compressed and fixed through the action of the fixing tube 112.

[0053] In the specific settings of the first connecting structure and the second connecting structure of the present embodiment, buckle blocks 1112 are provided on both sides of the lower outer wall of the connecting column 113, and a buckle groove 1113 matched with the buckle block 1112 is provided on the upper inner wall of the connecting sleeve 119. A roll-out groove 1114 is connected to one side of the buckle groove 1113, and the roll-out groove 1114 extends to the upper wall opening of the connecting sleeve 119. By pressing the knob seat 118, the connecting column 113 moves downward to the connecting sleeve 119 located on the lower module. First, the buckle block 1112 on the connecting column 113 will enter the inner wall of the connecting sleeve 119 through the roll-out groove 1114, and then by rotating the knob seat 118, the knob seat 118 drives the buckle block 1112 on the connecting column 113 to rotate into the buckle groove 1113 to complete the knob fixation.

[0054] In this embodiment, the upper and lower sides of the fan module 4, the primary filter element module 5, and the secondary filter element module 6 are provided with circuit wiring heads 13 and data signal transmission connectors 14. The top sides of the primary filter module 1 are provided with circuit wiring heads 13 and data signal transmission connectors 14. The circuit wiring heads 13 and data signal transmission connectors 14 at the bottom of the fan module 4 are connected to the circuit wiring heads 13 and data signal transmission connectors 14 at both sides of the top of the primary filter module 1. The circuit wiring heads 13 and data signal transmission connectors 14 at the top of the fan module 4 are connected to the circuit wiring heads 13 and data signal transmission connectors 14 at both sides of the top of the primary filter module 1. The circuit wiring head 13 and the data signal transmission connector 14 at the top of the first-level filter element module 5 are connected with the circuit wiring head 13 and the data signal transmission connector 14 at the bottom of the second-level filter element module 6, and the circuit wiring head 13 and the data signal transmission connector 14 at the top of the second-level filter element module 6 are connected with the circuit wiring head 13 and the data signal transmission connector 14 at the bottom of the ozone disinfection module 7. This ensures the transmission of electricity and the data collection of each module can be timely transmitted to the output device for output display.

[0055] In this embodiment, the fan module 4, the primary filter element module 5, the secondary filter element module 6, and the primary filter module 1 are all provided with a signal recording board 1015, and the signal recording board 1015 is used to record the usage time of the module, and the time is recorded and read through the internal NFC chip. For example, when the filter element is replaced, the signal recording board 1015 is connected to the NFC chip on the filter element to identify the usage time. The time for a new replacement is zero. If it has been used before and is now replaced in the disinfector, the output time of the signal recording board 1015 is the cumulative time used before.

[0056] Specifically, the power socket 12 transmits external electricity to the disinfection machine, and realizes independent power supply to each module through the circuit terminal 13, so that the signal recording board 1015 in each module can work, and the data signal transmission connector 1015 realizes the transmission of the data signal collected by each layer, and transmits the signal to the control main board 16 for recording.

[0057] When the internal filter element is replaced according to the technical solution, first, an external force is applied to press the spring cap 104 to separate the buckle cap groove 1013 from the spring cap. At this time, the ozone disinfection module 7 and the secondary filter element module 6 can be separated and disassembled, and then the knob fixing structure 11 is rotated. Secondly, the buckle block 1112 on the connecting column 113 will be separated from the buckle groove 1113 through the reverse rotation of the knob seat 118, and the buckle block 1112 will slide out of the roll-out groove 1114. Under the action of the second reset spring 1111, the modules are disassembled to replace the filter element or other components. After a certain period of time, the knob seat 118 is rotated again, and the knob seat 118 drives the buckle block 1112 on the connecting column 113 to rotate into the buckle groove 1113 to complete the knob fixation.

[0058] The disinfection system of the rotary air disinfector includes a control mainboard 16 arranged on one side of the air flow box and a display screen 9 located on the outer wall of the ozone disinfection module. The control mainboard 16 is respectively connected to the fan module 4, the sterilization device, the display screen 9, and the signal recording board 1015. The fan module 4 is connected to the negative ion generator to mix the negative ions in the air. The sterilization device is connected to the ozone generator to sterilize and disinfect the air in the air flow box. The signal recording board 1015 is connected to the NFC chip. The NFC chip is easy to be identified by the signal recording board, and the cumulative usage time of the NFC chip under the module is recorded. The above-obtained usage time records are summarized by the control mainboard 16, and finally the output value is displayed on the display screen 9 for the user to read.

[0059] In the disinfection system of this embodiment, the entire operation process can be controlled by a computer, and with the addition of a PLC, etc., automated operation control can be achieved. In each operation link, sensors can be set to provide signal feedback to achieve sequential execution of steps. These are all common knowledge of current automated control and will not be described in detail in this embodiment.
