Detailed Description
The utility model is further described below with reference to the accompanying drawings and specific embodiments.
Example 1
As shown in fig. 1, the dust suction apparatus of the present embodiment includes a suction duct 10 and a fan 20. The fan 20 generally has two ports, one being an air inlet port and the other being an air outlet port. The fan 20 is an existing conventional product, and the detailed structure thereof is not described herein.
Both ends of the dust suction pipeline 10 are provided with openings, and a through channel is formed in the middle of the dust suction pipeline 10, wherein the opening at one end of the dust suction pipeline 10 is communicated with the air outlet port of the fan 20, and the opening at the other end of the dust suction pipeline 10 is a garbage outlet 11.
The middle of the dust absorption pipeline 10 is provided with an installation cylinder 30. One side of the mounting cylinder 30 is connected with the dust suction pipeline 10, and the cavity 31 inside the mounting cylinder 30 is communicated with a channel in the dust suction pipeline 10; the other side of the mounting cylinder 30 is provided with an opening as a waste inlet 32.
A garbage sweeping mechanism is further arranged in the cavity 31 of the installation cylinder 30 and is used for sweeping the fine garbage outside or near the garbage inlet 32 into the dust suction pipeline 10.
When the fan 20 works, airflow is generated in the dust collection pipeline 10, and the airflow direction is from the air outlet of the fan 20 to the garbage outlet 11, so that the fine garbage swept into the dust collection pipeline 10 is blown to the garbage outlet 11 to be discharged.
In this embodiment, the garbage sweeping mechanism is preferably a roller brush 33, and the bristles of the roller brush 33 can extend out of the garbage inlet 32. A rotating shaft penetrates through the middle of the rolling brush 33, two ends of the rotating shaft are fixed on the side wall of the installation cylinder 30, and the rolling brush 33 can be driven to rotate in the installation cylinder 30. When the rolling brush 33 rotates, the fine garbage outside or near the garbage inlet 32 is swept into the dust absorption pipeline 10, and the fine garbage swept in by the rolling brush 33 is carried to the garbage outlet 11 by the airflow blown by the operation of the fan 20. The bristles of the rolling brush 33 are soft bristles, and the bristles are dense enough to substantially close the garbage inlet 32 when the rolling brush rotates, so that the airflow blown by the fan 20 does not substantially flow out from the garbage inlet 32 to the outside, and thus fine garbage is prevented from being blown out from the garbage inlet 32.
The rolling brush 32 can be driven to rotate in a plurality of ways, and in the embodiment, any one of the following two ways is preferred:
i) one end of the rolling brush 33 is fixed with a gear 330; a toothed impeller 34 is provided in the suction duct 10, the toothed impeller 34 being located inside the gear 330 and engaging therewith. When the fan 20 rotates, the blown air blows the toothed impeller 34 to rotate, and then drives the rolling brush 33 to rotate.
II) as shown in FIG. 2, a driving motor 35 is provided at one end of the rolling brush 33, and an output shaft of the driving motor 35 is fixed with the rolling brush 33, so that the driving motor 35 directly drives the rolling brush 33 to rotate.
It is to be understood that in the present invention, fine waste can be understood as including dust, and sometimes both can be understood as equivalent, interchangeable concepts.
When the dust suction device is used, the garbage outlet 11 of the dust suction pipeline 10 can be arranged in the garbage can, so that fine garbage can be swept into the garbage can. When in actual use, the garbage can be paved with garbage bags under common conditions. Therefore, in the present invention, the fine garbage is sucked into the garbage can, which means that the fine garbage can be directly sucked into the garbage bag, and the garbage bag can be directly discarded as a disposable accessory.
Preferably, the upper end of the dust suction pipe 10 is bent to one side, so that the garbage outlet 11 at the upper end of the dust suction pipe 10 is easily placed or faces into the garbage can, and is convenient to use. The garbage outlet 11 is preferably directed downward (either vertically downward or obliquely downward). When the garbage outlet 11 is arranged in the garbage can or above the garbage can, small garbage can smoothly enter the garbage can when being discharged.
The flow velocity of the fine garbage discharged from the garbage outlet 11 is too high, so that the fine garbage is easily scattered from the garbage can or rushes out the fine garbage in the garbage can. The upper end of the dust suction pipe 10 is bent to one side, so that the air flow direction is also bent at the position, and the effect of reducing the wind speed is achieved to a certain degree. In order to further reduce the flow rate of the fine waste discharged from the waste outlet 11, a speed reducing mechanism 40 for reducing the flow rate is further provided at the waste outlet 11.
As shown in fig. 3, as a preferable scheme, the speed reducing mechanism 40 includes a wind speed reducing impeller 41 and a shaft 42 penetrating through the middle of the wind speed reducing impeller, and both ends of the shaft 42 are connected to inner walls of both sides of the dust outlet 11 of the dust collection pipeline 10. The two ends of the shaft 42 are rotatably connected with the inner walls of the two sides of the garbage outlet 11 of the dust suction pipeline 10, and at this time, the wind speed reducing impeller 41 and the shaft 42 are fixed together and cannot rotate relatively; or, the two ends of the shaft 42 are fixedly connected with the inner walls of the two sides of the garbage outlet 11 of the dust suction pipeline 10, and at this time, the wind speed reduction impeller 41 and the shaft 42 can be sleeved together in a relatively rotating manner. No matter how the wind-speed reduction impeller 41 and the middle shaft 42 are fixed, the wind-speed reduction impeller 41 can be blown to rotate when the airflow passes through, and the flow speed of the airflow is weakened and reduced in the process.
Referring to fig. 4, as another preferred scheme, the speed reducing mechanism 40 is a speed reducing air nozzle 43 connected to the waste outlet 11 of the dust collecting duct 10, and a plurality of dense air holes 430 are further formed thereon. The airflow carrying the fine garbage in the dust suction duct 10 is discharged through the plurality of ventilation holes 430 of the speed-reducing air nozzle 43, and the flow rate of the airflow can be weakened and reduced.
Preferably, the speed-reducing air nozzle 43 is a box body shaped like a V, the rear side wall of the middle part of the speed-reducing air nozzle 43 is connected with the upper end of the dust suction pipeline 10, and a cavity 431 communicated with the dust suction pipeline 10 is arranged inside the speed-reducing air nozzle 43. The plurality of air holes 430 are formed on the sidewall of the speed-reducing tuyere 43. The apertures of the plurality of air holes 430 on the side wall of the speed-reducing air nozzle 43 are small, the aperture is preferably less than or equal to 1mm, and the fine garbage is not easy to be rapidly sprayed out from the air holes 430, but loses most of kinetic energy and falls into the garbage can under the action of gravity. At the same time. Since the speed-reducing tuyere 43 is substantially V-shaped, the front side wall thereof also has a certain effect on speed reduction.
Further, the lower side wall of the velocity-reducing tuyere 43 is provided with a large opening 432, so that the airflow carrying the fine garbage is mainly directed downward when being discharged from the garbage outlet 11. It should be understood that the waste outlet 11 is not intended to mean a hole or an opening at this time, but includes the concept of a plurality of ventilation holes 430 on the side wall of the speed-reducing tuyere 43 and a larger opening 432 at the lower side wall of the speed-reducing tuyere 43.
It will be readily understood that the specific structure of the speed reducing mechanism 40 is not limited in the present invention, and those skilled in the art can adopt other structure of speed reducing mechanism in case of reducing the flow rate to make the fine garbage smoothly drop into the garbage can when the fine garbage is discharged from the garbage outlet 11.
Compared with the prior art, the dust suction device has the advantages that fine garbage such as dust can be directly discharged into the garbage can while dust is sucked, the dust bag does not need to be cleaned manually like the existing dust collector, the dust suction device is clean and sanitary, and the dust suction device is very convenient to use.
Example 2
As shown in fig. 5, the dust-absorbing trash can of this embodiment includes a can 50 and a dust-absorbing device, and a receiving cavity 51 for laying a trash bag (not shown) is formed in the middle of the can 50.
Preferably, the sidewall of the tub 50 has a certain thickness. The dust suction device is embedded in the sidewall of the tub 50. A first opening 52 is formed at a front side edge of a lower portion of the tub 50, and a second opening 53 is formed at an inner side of an upper portion of the tub 50. The dust inlet 32 of the dust extraction device is located at the first opening 52 and the dust outlet 11 of the dust extraction device is located inside the second opening 53, emerging from the second opening 53. The waste outlet 11 faces the interior of the receiving cavity 51 of the can 50. The dust collection trash can of the embodiment can be used as a common trash can and can also be used as a dust collector. A garbage bag is generally laid in the can body 50, and the fine garbage sucked by the dust suction device is directly discharged into the garbage bag, so that the garbage bag can be discarded along with the garbage.
Referring to fig. 6, in the present preferred embodiment, the dust suction duct 10 is composed of three main parts, including a first duct section 101, a second duct section 102 and a third duct section 103, which are sequentially communicated, wherein:
the second pipe section 102 is located inside the first opening 52, and the installation cylinder 30 is connected to the front side of the second pipe section 102, so that the garbage inlet 32 on the front side of the installation cylinder 30 is located right at the first opening 52;
the first pipe section 101 is arranged in the right edge of the lower part of the barrel 50, one end of the first pipe section 101 is communicated with the air outlet port of the fan 20, and the other end of the first pipe section 101 is bent towards one end of the second pipe section 102 and is connected with the second pipe section;
the third pipe section 103 is approximately vertically arranged in the side wall of the barrel body 50, and the lower end of the third pipe section 103 is bent towards the other end of the second pipe section 102 and is connected with the other end; the upper end of the third pipe segment 103 is provided with the garbage outlet 11, and extends into the accommodating cavity 51 in the barrel 50 from the second opening 53 at the inner side of the upper part of the barrel 50.
The lower bent part of the dust collection pipeline 10 is less, and only the joint of the second pipe segment 102 and the first pipe segment 101 and the third pipe segment 103 is bent. Because the second pipe section 102 and the first pipe section 101 are correspondingly located at two adjacent side edges, the turning radii of the two positions are large, so that the airflow is smoother when passing through, and the blowing of the fine garbage at the garbage inlet 32 into the garbage can is facilitated.
As shown in fig. 7, a third opening 55 is further disposed on an inner wall of the barrel 50 as an air suction opening, and the third opening 55 is communicated with an air inlet of the fan 20. Therefore, when the garbage bag is laid in the accommodating cavity 51, the air in the accommodating cavity 51 is sucked away by the fan 20, so that the effect of stabilizing the garbage bag can be achieved, and the garbage bag is prevented from being blown up by the airflow blown out from the garbage outlet 11 to influence the use; at the same time, the fine garbage discharged from the garbage outlet 11 is prevented from being scattered outside the can 50.
The embodiments of the present invention are merely illustrative, and not restrictive, of the scope of the claims, and other substantially equivalent alternatives may occur to those skilled in the art and are within the scope of the present invention.
