The present invention relates to the field of vacuum suction, and in particular to an ionization decomposition air type vacuum pump. It includes a vacuum pump, and also includes: a decomposition unit, connected to the vacuum pump, including a transfer mechanism, a decomposition mechanism and a plurality of capillaries, the decomposition mechanism is arranged beside the vacuum pump, the decomposition mechanism includes a spiral pipe, one end of the spiral pipe is connected to the input end of the vacuum pump, the transfer mechanism is arranged on the side of the spiral pipe away from the vacuum pump, the transfer mechanism includes a connecting cone, the small end of the connecting cone is connected to the other end of the spiral pipe, and a plurality of capillaries are arranged in an array at equal angles along the circumferential direction of the large end of the connecting cone; an ionization mechanism, connected to the connecting cone, including a conical electric field, a filter screen and a plurality of cleaning brushes, the conical electric field is arranged at one end of the connecting cone away from the spiral pipe, the large end of the conical electric field is connected to the connecting cone, the filter screen is coaxially fixed with the small end of the conical electric field, and a plurality of cleaning brushes are arranged in a circumferential array rotationally beside the filter screen and against the filter screen.

This invention relates to an integrally woven pile sandwich mesh fabric and its weaving method. The integrally woven pile sandwich mesh fabric is woven in one piece using a warp knitting machine equipped with no fewer than seven ground comb bars. It includes a face layer, a middle layer, and a bottom layer. The face layer is woven using the chain blocks of the jacquard or ground comb on the machine in any weave pattern. The middle layer is woven using yarns connected to the face and bottom layers in a weave pattern. The bottom layer is woven using the chain blocks of the jacquard or ground comb on the machine in any weave pattern. This invention, through reasonable process design of each comb bar, fully utilizes the advantages of jacquard and ground combs, combines the variations in yarn threading of the comb bars, and employs precise design and the use of synthetic fibers to produce an integrally woven sandwich three-dimensional pile mesh fabric with characteristics of being skin-friendly and soft, lightweight, high-performance, and structurally stable.
