Dust absorption passage arranges along first direction, and gas passage arranges along second direction, and it is 5-60 degree that first direction and second direction intersect angle, due to dust absorption passage straight line, pick-up performance is good, and it is 5-60 degree that gas passage and dust absorption passage intersect angle, dust can be blown out to dust mouth, drifting dust is effective.
Gas passage number is a plurality of, and a plurality of gas passages are along the axial annular arranged in arrays of dust absorption passage, and negative pressure is evenly arranged, and negative pressure is large, and pick-up performance is good.
Entering-dust mouth becomes the little pyramidal structure of outer imperial palace, and pick-up performance is good.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 has illustrated the structural representation of dust collection equipment.
The specific embodiment
Please refer to Fig. 1, dust collection equipment, comprises a dust suction seat 1, an air pump 2, a sweep-up pipe 3 and a dress dirt container 4.
This dust suction seat 1 is established a dust absorption passage 11 and at least one gas passage 12,11 one-tenth revolving structures of this dust absorption passage, this gas passage 12 also becomes revolving structure, this dust absorption passage 11 is arranged along first direction, this gas passage 12 arranges along second direction, and this first direction and second direction intersect, and this crossing angle is 5-60 degree, one most preferred embodiment is 40-50, for example 45 degree.Among the present embodiment, this first direction is dust absorption passage 11 axis and along entering dirt direction, and this second direction is gas passage 12 axis and along airintake direction.Best, these gas passage 12 numbers are a plurality of, and the plurality of gas passage 12 is along the axial annular arranged in arrays of dust absorption passage 11.
This dust absorption passage 11 has an entering-dust mouth 111, a dust mouth 112 and and enter dirt interlude 113 between entering-dust mouth 111 and dust mouth 112.This gas passage 12 has an air intake 121, the air flue interlude 123 of a gas outlet 122 and between air intake 121 and gas outlet 122.
