Embodiment
About aforementioned and other technology contents, characteristics and effect of the present invention, in the detailed description of following cooperation two preferred embodiments with reference to the accompanying drawings, can clearly present.
Before the present invention is described in detail, be noted that in the following description content similarly assembly is to represent with identical numbering.
Consult Fig. 2 and Fig. 4, first preferred embodiment with casing device 2 of dust removal apparatus of the present invention comprises a casing 3, a fan 4 and a dust removal apparatus 5.
The method of reduction case fan absorption dust of the present invention comprises following steps:
Step 61: interference in air flow assembly 52 is arranged at casing 3 internal faces and is positioned at the upstream end of fan 4, flow to the air-flow of fan 4 in order to interference.In the present embodiment, be to use a lamellar body as interference in air flow assembly 52, this lamellar body is to become to be obliquely installed, and above-mentioned plane of inclination 521 is a side surface of lamellar body.
Step 62: will stick assembly 51 and be arranged at casing 3 internal faces and be positioned at gas channel 31, and be positioned at the downstream part of interference in air flow assembly 52, this sticks assembly 51 in order to stick dust.Stick that assembly 51 has stickiness towards a side 511 of gas channel 31 and in order to stick dust.And in the present embodiment, stick assembly 51 and be one and stick in the two-sided tape of casing 3 internal faces, but not as limit.
When fan 4 runnings, can form owing to the effect of fan 4 suctions in the gas channel 31 toward fan 4 airflow flowing, and when air-flow gas during by interference in air flow assembly 52, the design meeting of the plane of inclination 521 of interference in air flow assembly 52 forms the air-flow that passes through and disturbs, make air-flow form turbulent flow at interference in air flow assembly 52 top ends, because this turbulent flow can slow down the speed that air-flow flows toward fan 4, therefore, just can allow the dust that carried secretly by air-flow have an opportunity at this moment, and be attached on the side 511 of sticking assembly 51 because of self gravitation falls.So, just can reduce dust that air-flow carries secretly along with air flow stream is attached on the fan 4 toward fan 4, and then avoid fan 4 to influence its exhausting usefulness because of too much dust adheres to.
What remark additionally is, owing to considering that sticking assembly 51 can stick a lot of dusts in use for some time and need to change, in the present embodiment, casing 3 comprises a housing 32 and a movable plate 33, housing 32 has an opening 321, and movable plate 33 is incorporated into housing 32 separably and covers opening 321.Interference in air flow assembly 52 with stick the internal face that assembly 51 all is connected in movable plate 33, so in use for some time, movable plate 33 can be taken off will stick assembly 51 by housing 32 and change, and that interference in air flow assembly 52 more can be designed to movable plate 33 is one-body molded.
Consult Fig. 3, be second preferred embodiment with casing device 2 of dust removal apparatus of the present invention, the difference of itself and first preferred embodiment is the position that is provided with of interference in air flow assembly 52.
In the present embodiment, interference in air flow assembly 52 is connected in housing 32 internal faces and only sticks assembly 51 and is arranged at movable plate 33 internal faces.Because the working principle of second preferred embodiment is identical with the working principle of first preferred embodiment, in this no longer repeat specification.
In sum, the present invention is by the setting of interference in air flow assembly 52, disturb the air-flow that flows to fan 4 by this, and then the dust that carried secretly by air-flow is fallen within stick assembly 51 and attached to and stick assembly 51, the dust that the reduction air-flow is carried secretly is sent to fan 4 and is attached to fan 4, really can effectively reach the dust absorption that reduces fan 4, so can reach purpose of the present invention really.
The above-described content of thought, it only is preferred embodiment of the present invention, can not limit scope of the invention process with this, promptly every claims scope and invention description content are done according to the present invention simple equivalent variations and modification all still belong in the scope that patent of the present invention contains.
