[0023] It should be noted that: in this embodiment, the second solenoid valve 9 is in a normally closed state, and when cleaning and replacing the filtering component 6, the second solenoid valve 9 needs to be opened alternately. At the same time, the flow meter 10 can detect the heating volume, and when the filtered heating volume reaches the set value, an alarm is given to ensure that the filtering component 6 is cleaned in time.

[0024] In this implementation scheme: two groups of filtering components 6 are provided. During actual use, the start and stop of specific solenoid valves can be controlled to alternately clean the two groups of filtering components 6 without shutting down the machine. At the same time, the filtering box 5 is easy to disassemble, and it is convenient to replace and maintain the filtering component 6, so as to ensure a good experience for users.

[0025] As Figure 2 shown;

[0026] In an optional embodiment, the quick-connection component 3 includes a first limit ring 301 provided at the end of the third heating and ventilation pipe 4 and a second limit ring 302 provided at one end of the second heating and ventilation pipe 2 and the fourth heating and ventilation pipe 7. A locking ring 303 that is rotationally connected and matched with the second limit ring 302 is rotatably provided at the end of the third heating and ventilation pipe 4. Metal gaskets 11 are provided between the abutting surfaces of the second heating and ventilation pipe 2 and the third heating and ventilation pipe 4 and between the abutting surfaces of the third heating and ventilation pipe 4 and the fourth heating and ventilation pipe 7.

[0027] In this embodiment: The metal gasket 11 is placed at the end of the third HVAC pipe 4, and the locking ring 303 is screwed and fixed to the second limiting ring 302, so as to achieve the sealing and fixing of the third HVAC pipe 4 to the second HVAC pipe 2 and the fourth HVAC pipe 7 respectively.

[0028] As Figure 3 shown;

[0029] In an alternative embodiment, the filter box 5 includes symmetrically arranged first sealing boxes 501 and second sealing boxes 502, and both the first sealing box 501 and the second sealing box 502 are detachably fixed through the flange plates 503 on their outer sides.

[0030] In this embodiment: Using bolts and flange plates 503 can ensure the quick disassembly and installation of the first sealing box 501 and the second sealing box 502.

[0031] As Figure 4 shown;

[0032] In an alternative embodiment, the filter assembly 6 includes a mounting frame 601 disposed inside the first sealing box 501 and the second sealing box 502, and a plurality of filter plates 602 are equidistantly inserted through the mounting frame 601.

[0033] In this embodiment: By pulling the mounting frame 601, all the filter plates 602 can be taken out from the first sealing box 501 and the second sealing box 502, so as to achieve quick replacement and cleaning.

[0034] The working principle and usage process of the present utility model: During actual use, the first solenoid valve 8 and the second solenoid valve 9 are electrically controlled through an external control box. During actual use, the second solenoid valve 9 is in a normally closed state, and the heating air is discharged into the first HVAC pipe 1 in the arrow direction. The heating air enters the filter box 5 through the second HVAC pipe 2 and the third HVAC pipe 4, so as to clean the heating air by using the filter plates 602. The cleaned heating air enters the first HVAC pipe 1 again along the third HVAC pipe 4 and the fourth HVAC pipe 7; when it is necessary to disassemble one of the filter boxes 5, it is necessary to first open the second solenoid valve 9 directly above this filter box 5 and close the first solenoid valve 8 corresponding to and communicating with this filter box 5. At the same time, select and remove the locking ring 303 to disassemble this filter box 5. After cleaning and installing this filter box 5, close the corresponding second solenoid valve 9 and open the first solenoid valve 8. The disassembly method of the other filter box 5 is the same.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
