Dust collector

Abstract

A dust collector comprises: a first container, a vacuum motor, a first-flow guiding unit, and a second flow-guiding unit; wherein the first container is set with a first tube-body, and the vacuum motor is set on a cover-body; wherein the motor is set with a filter, wherein the first flow-guiding unit and the second flow-guiding unit are respectively detachably combined with a second container and a third container; wherein the second flow-guiding unit is located in the first flow-guiding unit, and the first tube-body sucks in air, so that the dust and debris in the air enter the first container; wherein the air sequentially passes through the first flow-guiding unit and the second flow-guiding unit to form a vortex to make the fine dust fell into the second container and the third container; and the air is finally discharged by the vacuum motor after passes through the filter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(7) The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following detailed description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

(8) The foregoing and other aspects, features, and utilities of the present invention will be best understood from the following detailed description of the preferred embodiments when read in conjunction with the accompanying drawings.

(9) Please refer to FIG. 1 and FIG. 2, the dust collector 1 of the present invention comprises: a first container 10 set with a first tube-body 11, and two ends of the first tube-body 11 are respectively located on the outer side and the inner side of the first container 10; wherein one end in the inner side of the first container 10 has a bent portion 111 that faces toward the first container 10, thereby forming a vortex when air enters; please refer to FIG. 2 and FIG. 4, in this embodiment, the bottom of the first container 10 has a through-hole 12, and the first container 10 is accommodated and set in a fourth container 14 sleeved and set with a bag-body 13; a vacuum motor 20 including an air inlet (not shown in the figure), wherein the vacuum motor 20 is set on a top surface of a cover-body 15, and the cover-body 15 is set with a through-hole 151 corresponding to the air inlet; wherein the through-hole 151 is detachably combined with a filter 16 and is located on the bottom surface of the cover-body 15; a first flow-guiding unit 30 comprising a first inner-tube 31, a plurality of first flow-guiding tubes 32, and a first outer-tube 33; wherein the first inner-tube 31 has a first convergent-portion 311, and one end of the first inner-tube 31 is combined with the bottom surface of the cover-body 15; such that the filter 16 is located in the first inner-tube 31; wherein the diameter of one end of the first inner-tube 31 combined with the cover-body 15 is larger than the other end; please refer to FIG. 4 and FIG. 5, each of the first flow-guiding tubes 32 is obliquely distributed and set on the outer side of the first inner-tube 31; wherein the first outer-tube 33 is combined on the outer side of each of the first flow-guiding tubes 32, and the length of the first outer-tube 33 is greater than the length of the first inner-tube 31; wherein the first outer-tube 33 has a second convergent-portion 331, and the bottom of the second convergent-portion 331 is set with a first sticking-engaging slot 332 for providing to detachably combine with a second container 333; a second flow-guiding unit 40 comprising a second inner-tube 41, a plurality of second flow-guiding tubes 42, and a second outer-tube 43; wherein the second inner-tube 41 is combined on the outer side of the first inner-tube 31 and is located inside the first outer-tube 33; wherein each of the second flow-guiding tubes 42 is obliquely distributed and set on the outer side of the second inner-tube 41, and the second outer-tube 43 is combined on the outer side of each of the second flow-guiding tubes 42, wherein the length of the second outer-tube 43 is greater than the length of the second inner-tube 41; wherein the second outer-tube 43 has a third convergent-portion 431, and the bottom of the third convergent-portion 431 is set with a second sticking-engaging slot 432 for providing to detachably combine with a third container 433.

(10) After the vacuum motor 20 of the dust collector 1 of the present invention is started, air enters the first container 10 from the first tube-body 11; and the dust or debris foreign matter will be retained in the first container 10 initially; then the air in the first container 10 will enter along each of the first flow-guiding tubes 32 to further retain the dust of the air in the second container 333; at the same time, the air enters the third container 433 along the second flow-guiding tubes 42 from the first flow-guiding unit 30; and the dust and the fine dust of the air are again retained in the third container 433; then, the air is discharged through the filter 16, and the filter 16 can capture finer dust of the air, making the discharged air harmless to the human body.

(11) In short, the dust collector 1 of the present invention has three containers for retaining the dust or debris foreign matter, which can purify the air by the filter 16 and simultaneously have functions of sucking dust, collecting dust, and purifying the air.

(12) Please refer to FIG. 6, after the dust collector 1 of the present invention is used, the first container 10 can be taken out; since the first container 10 and the fourth container 14 are set with the bag-bodies 13, dust and debris will fall into the bag-bodies 13; and the bag-bodies 13 can be quickly packed to be conveniently cleaned.

(13) Moreover, the first container 10 can also be not set with the through-hole 12, so that the dust and debris will fall inside the first container 10, so the dust and debris can be separately poured into the garbage bag for cleaning.
