[0002] The suction pump of the vacuum cleaner that is widely circulated in the market now is a vacuum pump that uses the centrifugal vacuum principle of the single-phase motor fan blade to inhale. It has relatively large deficiencies in use, mainly due to the high power of the vacuum cleaner single machine motor, large noise, and large reactance radiation. , causing great interference to other household appliances and causing secondary pollution when the vacuum cleaner is used
Therefore, the experience of most families in the use of vacuum cleaners is not comfortable, but there is no choice, because so far there is no suitable vacuum cleaner suction pump

A vacuum cleaner and its air cylinder type circulating air return vacuum lead screw shaft cup silent suction pump, the suction pump includes a closed cylinder and a screw installed in the cylinder, the two ends of the screw are respectively fixed on the The bottom surface and the top surface of the cylinder body, and one end of which is located outside the cylinder body, is covered with a screw gear, which is connected to the output shaft of the drive motor for transmission; the bottom surface of the cylinder body is provided with a suction port. There is a first one-way valve in the suction port, which is connected to the air intake mechanism; the top of the cylinder is provided with an exhaust port; the screw is covered with a nut, and the nut is covered with a cup skeleton , the outer circumference of the cup frame is provided with a cup, which is in close contact with the inner wall of the cylinder; the cup frame is provided with a through hole, and a second one-way valve is provided on one side of the through hole; the first one-way valve and the second one-way valve Two one-way valves allow gas to flow only from the suction port to the exhaust port; the exhaust port is connected to the garbage collection port through the circulation pipe. The invention has low energy consumption and great suction, and will not cause secondary air pollution.
Description
technical field [0001] The invention relates to an air suction pump, in particular to an air cylinder type circulating air return vacuum screw shaft cup silent air suction pump and a vacuum cleaner containing the air suction pump. Background technique [0002] The suction pump of the vacuum cleaner that is widely circulated in the market now is a vacuum pump that uses the centrifugal vacuum principle of the single-phase motor fan blade to inhale. It has relatively large deficiencies in use, mainly due to the high power of the vacuum cleaner single machine motor, large noise, and large reactance radiation. , It will cause great interference to other household appliances, and produce secondary pollution when the vacuum cleaner is used. Therefore, the experience of most families in the use of vacuum cleaners is not comfortable, but there is no choice, because no suitable vacuum cleaner suction pump has appeared so far. Contents of the invention [0003] In order to solve the...
