Exhaust gas filter of dust collector

Abstract

The invention discloses an exhaust gas filter of a dust collector, which comprises a filter core frame, a filter core, a button and a spring frame, wherein a pull handle and a button groove are formed at one end of the filter core frame, and a filter core frame body is formed at the other end of the filter core frame and is connected with the spring frame; the filter core is installed in the filter core frame, and a chock block and a contact point are formed at one side of the filter core; a spring is arranged in the spring frame; the contact point is a strip protrusion with certain inclination, and the inclination direction of the contact point faces to the other side of the filter core; and one end of the spring is fixed on the spring frame, and the other end of the spring is in contactwith the chock block. In the invention, because the exhaust gas filter is arranged, the closure without a container is avoided, thereby eliminating the hidden trouble caused by incorrect manipulation.

Description

technical field [0001] The invention belongs to a vacuum cleaner, in particular to a filter exhaust device of the vacuum cleaner. Background technique [0002] Vacuum cleaner is a kind of household appliance for indoor cleaning and sanitation, which is used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe. [0003] When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air inside the vacuum cleaner, forming an instantaneous vacuum inside the vacuum cleaner, and forming a relatively high negative pressure diffe...

AI Technical Summary

Problems solved by technology

[0009] In the exhaust filter device of the vacuum cleaner, since the filter element is installed in the filter element compartment or not installed in the filter element compartment, the rear cover can be covered, so when the user is using the vacuum cleaner, after cleaning the filter element, if he forgets to put the filter element into the filter element In the bin, the back cover can still be closed, forming a "closed without container", in this case, if you continue to use the vacuum cleaner, it will cause adverse consequences
