Description

Technical Field

[0001] The utility model relates to the field of cleaning equipment, in particular to a HEPA leak-proof structure used in cleaning equipment. Background Art

[0002] Most existing cleaning equipment is equipped with a dirt suction box, which has a dirt inlet and an air suction port. In order to prevent the polluted gas from being directly discharged into the air after being extracted through the air suction port, causing secondary pollution, a HEPA filter is usually installed at the air suction port to filter the gas passing through the air suction port. Usually, the dirt suction box consists of a box body and a box cover. The top side of the box cover is provided with a HEPA frame assembly slot, in which a detachable HEPA frame is installed, and in which a detachable HEPA frame is provided. In daily use, users are prone to miss installing the HEPA filter, which leads to secondary pollution, and even particulate matter is sucked into the vacuum motor, causing malfunctions.

[0006] The preferred technical solution is: an interference rod assembly groove is provided on the top side of the box cover, and the interference rod can be movably arranged in the interference rod assembly groove up and down; a spring is also provided in the interference rod assembly groove, one end of the spring is against the bottom of the interference rod assembly groove, and the other end of the spring is against the interference rod and applies a vertical upward force to the interference rod.

[0007] The preferred technical solution is: the bottom of the HEPA rack assembly groove is provided with an air outlet connected to the interior of the dirt suction box.

[0008] The preferred technical solution is: a detachable Hepa is installed in the Hepa frame.

[0009] Due to the application of the above technical solution, the utility model has the following beneficial effects:

[0010] The utility model proposes a HEPA leakage prevention structure for use in cleaning equipment, wherein an interference rod which can elastically extend and retract in a vertical direction is arranged on the top side of a box cover of a dirt suction box, and an interference block corresponding to the interference rod is arranged on the HEPA frame, that is, when the HEPA is not installed on the box cover, the interference rod is always in a state of extending out from the top side of the box cover, and the dirt suction box in this state cannot be assembled into the dirt suction box assembly groove on the cleaning equipment. This structure can prevent the dirt suction box from being installed in the cleaning equipment for use when the HEPA is not installed. BRIEF DESCRIPTION OF THE DRAWINGS
