Problems solved by technology

Since the filter element 5 often absorbs dust and causes blockage, it needs to be cleaned frequently. The operator can only rely on estimation to clean the filter element, and cannot accurately grasp whether the filter element is blocked, resulting in a decline in the filtering and cleaning ability.

Abstract

The invention discloses a filtering core blockage alarm device of a dust collecting barrel filtering device. The filtering device comprises a barrel body, an upper cover and a filter. The filter comprises a filtering bowl, a filtering core and a filter support. The filter also comprises the filtering core blockage alarm device arranged on the filter support. The filtering core blockage alarm device comprises a buzzer arranged on the filter support, and a micro-switch which is fixed on the bottom of the filter support and is connected with the buzzer. When a filtering core is blocked, due to a negative pressure generated in a cavity of the filtering core, the filtering core moves upwardly to press the micro-switch to turn on and make the buzzer give an alarm to remind a manipulator of cleaning the filtering core, thereby preventing the problem of a reduced filtering cleaning capability caused by filtering core blockage.

Description

technical field [0001] The invention belongs to a vacuum cleaner filter device, and in particular relates to a filter blockage alarm device of the filter device which gives an alarm when the filter core is blocked. 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. 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 insi...
