Description

Technical Field

[0001] The utility model relates to the technical field of medical cleaning and disinfection, in particular to a fan-filter integrated structure for a cleaning and disinfecting device. Background Art

[0002] Current washer-disinfectors with a capacity of approximately 500L utilize two vortex-type fans and a high-efficiency filter. The high-efficiency filter is installed separately in the filter box. The filter box has two connectors on the back, connected to the air inlets of the two fans with hoses. The air outlets of the two fans are then connected to the heating box. This method consumes a lot of space, and replacing the filters requires removing multiple screws. During installation, the filters are tightened with screws, which can sometimes cause problems, resulting in gaps between the filters and the filter box. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] like Figure 1-3 As shown, a fan-filter integrated structure for a cleaning and disinfecting device includes a fan, a filter box 12 and a filter box cover 1, the fan 4 is arranged in the filter box 12, the air outlet 2 is arranged at the top of the filter box cover 1, a sealing gasket 3 is arranged between the filter box cover 1 and the filter box 12, a mounting frame 13 is arranged at the lower end of the filter box 12, a tray 11 is arranged on the mounting frame 13, the tray 11 is connected to the high-efficiency filter 5, the upper end of the high-efficiency filter 5 is connected to the inside of the filter box 12, the lower end of the high-efficiency filter 5 is connected to the cam 9, the cam 9 is arranged on the rotating shaft 8, nuts 7 are arranged at both ends of the rotating shaft 8, and a fixing frame 6 is arranged at the lower end of the mounting frame 13.

[0016] The blower is a compact brushless DC high-pressure blower installed in the same housing as the HEPA filter. As shown in the figure, the HEPA filter is mounted at the bottom of the filter housing. The HEPA filter is mounted on a tray mounted to the bottom of the housing, with two cams holding the bottom of the tray in place. To disassemble, use a wrench to turn the nut. The nut and cam are welded to the shaft, which rotates around the mounting holes in the housing. Turning the nut rotates the cam, allowing the filter housing to be removed and pulled out using the tray. The two blowers are mounted on the filter housing cover, which is secured to the housing with a gasket. The cover includes an aviation plug for the blower wiring to ensure a tight seal. This creates a sealed space for the blowers, eliminating the need for any piping to connect to the blower inlet, ensuring that the air drawn into the blower is filtered air. Simply connect the blower outlet to the two outlets on the filter housing cover, which in turn connects the two outlets to the heating housing.
