Abstract

The invention relates to the field of household appliances, in particular to a dust collector air pressure detection protection system and a dust collector. The system comprises an air pressure detection module, a converter, a comparator and a controller; the air pressure detection module can detect the air pressure value of an air pressure sensitive position of the dust collector in real time during operation of the dust collector and converts the air pressure value into an electric signal; the converter is used for converting the electric signal into a digital signal reflecting the air pressure value; the comparator is used for comparing the digital signal with each preset critical value of the comparator to obtain a corresponding comparison result; the controller is used for receiving the comparison results output by the comparator, and outputting a corresponding control instruction to each executive component of the dust collector according to a comparison result; compared with theprior art, the technical effect are that the suction force of the dust collector is adjusted according to the change of the air pressure value in the dust collector detected in real time, and therefore it is effectively avoided that when a head filter of the dust collector is blocked or an air inlet is blocked, the suction force is reduced or a motor is damaged.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a vacuum cleaner air pressure detection and protection system and a vacuum cleaner. Background technique [0002] The people's need to improve the home environment, the frequency of use of vacuum cleaners is becoming more and more frequent. The principle of use of the vacuum cleaner is to use the vacuum formed by the suction motor inside the vacuum cleaner to suck external dust and other debris into the dust bucket through the main suction port, and the inhaled air is filtered and discharged from the tail of the machine. If the filter is polluted or the air inlet is blocked, the suction of the vacuum cleaner will weaken and the air pressure will increase. Not only will the cleaning work not be completed, but more seriously, the motor will be damaged. [0003] Existing vacuum cleaners usually use an air pressure switch for air pressure detection. When the filter is polluted, f...
