Detailed Description

The following description of the technical solutions in the embodiments of the present utility model will be clear and complete, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The embodiment of the utility model comprises the following steps:

The utility model provides a leakage-proof mechanism for a clean household appliance filtering HEPA, referring to fig. 1 and 2, comprising a machine body part 1 and a dust cup part 2, wherein a circuit board 3 is arranged on the machine body part 1, a filtering HEPA 4 is arranged in the dust cup part 2, one end of the machine body part 1, which is close to the filtering HEPA 4, is provided with an electrostatic ring 5 serving as an anode and a conductive spring plate 6 serving as a cathode, one end of the conductive spring plate 6 is provided with a conductive thimble 7, the conductive thimble 7 is positioned below the electrostatic ring 5, the upper end of the filtering HEPA 4 is provided with an upper cover 8, and when the filtering HEPA 4 is installed in the dust cup part 2, the upper cover 8 jacks up the conductive thimble 7 to enable the upper end of the conductive thimble 7 to be in contact with the electrostatic ring 5.

Preferably, two wires (not shown) are disposed in the body 1, one ends of the two wires are connected to the circuit board 3, and the other ends of the two wires are respectively connected to the electrostatic ring 5 and the conductive elastic sheet 6.
