A Low Noise Piston Pump Blowing Vacuum Cleaner

Abstract

The invention discloses a low-noise piston pump blowing dust collector. The low-noise piston pump blowing dust collector comprises a piston, an air cylinder, a motor and a single chip microcomputer, wherein a thread screw rod is fixed on the axis of a cavity of the air cylinder, and is connected with an output shaft of the motor by a speed reducing gear; the piston is arranged in the air cylinder and a thread hole is formed in the center of the piston; the thread screw rod penetrates through the thread hole; an air suction pipe opening is formed in one end of the air inlet pipe and the other end of the air inlet pipe is communicated with pipelines at the two ends of the air cylinder respectively; air inlet valves are arranged at the communicated parts; one end of an air outlet pipe is connected with an air blowing pipe opening and the other end of the air outlet pipe is communicated with pipelines at the two ends of the air cylinder respectively, and air outlet valves are arranged at the communicated parts; a magnet is fixed on the piston; Hall sensors are arranged at the two ends of the air cylinder; the two Hall sensors and the motor are connected with the single chip microcomputer. The two sides of the air cylinder corresponding to the two surfaces of the piston are sufficiently utilized: one side adopts positive pressure to blow the air and one side adopts negative pressure to blow the air, so that an air blowing and suction zero-damage dust removing function is realized. Strong air suction flow is generated without high-speed rotation so that the large noises annoying people are radically eliminated.

Description

technical field [0001] The invention relates to a low-noise piston pump vacuum cleaner. Background technique [0002] Due to its wide range of applications and large household popularity, vacuum cleaners have been continuously updated and their functions have been continuously expanded. [0003] For a long time, although vacuum cleaners have been constantly innovating, the annoying problem of high noise in household vacuum cleaners has not been fundamentally resolved; the reason is that strong suction is generated by the high-speed rotation of the fan blades, which inevitably produces mechanical noise from the high-speed rotation of the motor and wind noise from high-speed airflow. [0004] In order to adapt to the exquisite life of modern people, it is required to remove dust from many fine facilities without damage, such as dust removal for precious sculpture collections, wall hanging calligraphy and paintings, audio equipment, or electrical circuit boards, so as to avoid...

[0003] For a long time, although vacuum cleaners have been constantly innovating, the annoying problem of high noise in household vacuum cleaners has not been fundamentally resolved; the reason is that strong suction is generated by the high-speed rotation of the fan blades, which inevitably produces mechanical noise from the high-speed rotation of the motor wind noise

[0004] In order to adapt to the exquisite life of modern people, it is required to remove dust from many fine facilities without damage, such as dust removal for precious sculpture collections, wall hanging calligraphy and paintings, audio equipment, or electrical circuit boards, so as to avoid the typical problems of conventional vacuum cleaners, namely : If the distance is a little far away, the dust removal suction is not enough; when the suction nozzle is close to being blocked, the suction suddenly increases unexpectedly, which often causes major damage to the paper or the delicate parts of the equipment, such as the blade of the computer cooling fan being sucked off, the important paper being sucked, the sound The speaker is damaged, or the circuit board is damaged, etc.
