Description
Technical Field
The utility model relates to a cleaning equipment technical field especially relates to a FFU decides and protects structure.
Background
The FFU is a fan filtering unit in Chinese, the FFU which is universal in the market at present is directly horizontally placed on the framework, the filter screen is pressed by the self gravity of the FFU, no fastening measure is provided, and when the FFU is used, the FFU easily slides transversely and radially, so that the FFU is installed insecurely.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a FFU decides and protects structure has solved when using FFU, causes FFU horizontal, radial slip's problem easily
In order to achieve the above purpose, the utility model adopts the technical scheme that:
the utility model provides a FFU decides and protects structure, including air supply filter unit, air supply filter unit's bottom is provided with the location protection piece, the location protection piece is the bar form, be provided with a plurality of waist type hole on the location protection piece, be provided with a plurality of and waist type hole complex reference column on the air supply filter unit, wherein, the vertical setting in waist type hole, just the diameter of the main part of reference column is less than the aperture in waist type hole the tip of reference column is provided with spacing portion.
Furthermore, the positioning protection sheet is provided with a fixing protrusion, and a fixing groove matched with the fixing protrusion is formed in the filter below the air supply filter unit.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
the utility model discloses a FFU decides and protects structure, owing to be provided with the location protection piece in the bottom of air supply filter unit, the gravity lapse that the location protection piece passes through self, and location protection piece joint can prevent air supply filter unit's horizontal, radial slip through the location protection piece on the filter of air supply filter unit lower extreme this moment, makes air supply filter unit installation more firm.
