This utility model discloses a masterbatch hot melt filtering device, including a device body. A support rod is fixedly connected to the right side of the device body. A fixing plate is installed through the outer ring of the support rod near the right side. A limiting plate is fixedly installed through the outer ring of the support rod and is located on the left side of the fixing plate. A fastening nut is threadedly connected to the right side of the support rod and is located on the right side of the fixing plate. A groove is opened through the device body, and a filter frame is installed through the groove. A hydraulic telescopic rod is fixedly connected to one side of the filter frame through a connecting sealing plate. Two filtering positions are set on the filter frame, one for normal filtration and the other for standby filtration. When the filter screen needs to be replaced, the filter frame is adjusted under the action of the hydraulic telescopic rod, so that the standby filtration position replaces the normal filtration position. The normal filter screen is pushed out of the device body for subsequent filter screen disassembly and replacement, reducing long-term downtime.

The utility model discloses a disinfection device for air purifier belongs to air purifier disinfection field, aims at solving the user under prior art filter screen needs to dismantle multilayer buckle, screw or complex shell subassembly when replacing, and the operation process is complicated, especially for the old user or the person of limited physical existence obvious inconvenience, and more importantly, filter screen in long -term use will cause dust, aging to lead the efficiency to drop, and these components in the prior art structure are often blocked by the outer end filter screen or the body frame, and the filter screen system needs to be disassembled when disassembling and cleaning or replacing, not only increased the operation difficulty, also can cause the normal filter screen to be damaged because of frequent disassembly and assembly. Including air purifier shell, the upper end of air purifier shell is installed with upper cover, the inside of upper cover is provided with suction mechanism, the inside of air purifier shell is provided with dismounting mechanism, and the dismounting mechanism includes the upper limit ring that fixedly connected in the top of air purifier shell inside.
