Abstract
The utility model relates to a sander, and discloses a dedusting combined unit of a sander. The dedusting combined unit for the sander comprises a dedusting channel on a machine casing, a dust sucking blade, a dust sucking channel on a bottom board and a dust sucking through hole on a lining, wherein the dedusting combined unit is provided with a dust baffle ring and a wind baffle ring, the wind baffle ring is arranged under the dust sucking blade and is connected with the bottom board, one end of the dust baffle ring is tightly connected with the bottom board, and the other end is clung to the lower portion of the machine casing. The sander can effectively control the flowing direction of dust, and has better dust sucking effect.
Description
Technical field
The utility model relates to a kind of sander, relates in particular to a kind of dust suction assembled unit that is used for sander.
Background technology
In the prior art, sander sucks in the sander by the dust suction fan blade the dust that produces in its work.After dust enters in the sander by dust suction through hole and dust absorption passage,,, enter at last in the bag dust filter that is arranged on dust discharge passage one end, finish dust suction work by being arranged on the dust discharge passage on the casing along cavity between base plate and the casing.
Yet because sander base plate when work is done parallel swing with respect to casing, thereby there is the gap in the airtight space that can't form between casing and the base plate.Therefore, dust in being inhaled into sander after, a part can overflow along the gap between casing and the base plate, can't effectively control the flow direction of dust, influences pick-up performance.Simultaneously, because the space of dust suction fan blade blade face front end is bigger, the dust-absorbing airflow that makes the rotation of dust suction fan blade form is powerful inadequately, thereby influences pick-up performance.
Summary of the invention
The utility model is at the dust suction assembled unit that is used for sander that exists in the prior art, can't effectively control the flow direction of dust, the deficiency of pick-up performance difference provides a kind of flow direction that can effectively control dust, the assembled unit that is connected of the base plate of the sander that pick-up performance is good and casing.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
The dust suction assembled unit that is used for sander, comprise dust absorption passage on dust discharge passage on the casing, dust suction fan blade, the base plate and the dust suction through hole on the liner, above-mentioned dust suction assembled unit is provided with dust-blocking ring and wind loop, wind loop is positioned at the below of dust suction fan blade and is connected with base plate, dust-blocking ring one end closely is connected with base plate, and the other end is close to the casing below.
This dust suction assembled unit that is used for sander has been set up dust-blocking ring and wind loop.Dust-blocking ring blocks the gap between base plate and the casing, effectively blocks dust, stops dust to overflow, and the flow direction of control dust improves pick-up performance.Simultaneously, wind loop can effectively improve the dust-absorbing airflow intensity that the dust suction fan blade forms, and improves pick-up performance.
Above-mentioned base plate is provided with cannelure, and dust-blocking ring one end inserts cannelure.
This connected mode is simple in structure, easy to connect.
Above-mentioned dust-blocking ring is a wool elasticity dust-blocking ring.
Careful wool closely can effectively block dust, stops dust to overflow.Simultaneously, because dust-blocking ring has good elasticity, and the wool surface has good flexibility, can not produce excessive friction when making base plate with respect to the parallel swing of casing, the normal operating efficiency of assurance sander.

Fig. 2 is the utility model base plate and vertical view after liner is connected;
Fig. 3 is the A-A cutaway view of Fig. 2.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail, but is not restriction of the present utility model:
Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the dust suction assembled unit that is used for sander, comprise dust absorption passage 10 on dust discharge passage 7 on the casing 3, dust suction fan blade 4, the base plate 5 and the dust suction through hole 9 on the liner 8, above-mentioned dust suction assembled unit also is provided with dust-blocking ring 1 and wind loop 2, described wind loop 2 is positioned at the below of dust suction fan blade 4 and is connected with base plate 5, described dust-blocking ring 1 one ends closely are connected with base plate 5, and the other end is close to casing 3 belows.
Preferably be provided with cannelure 6 on the above-mentioned base plate 5, dust-blocking ring 1 one ends insert cannelure 6, and realization is connected with base plate 5.
Above-mentioned dust-blocking ring 1 can be high-density sponge elasticity dust-blocking ring, is preferably wool elasticity dust-blocking ring.
When the sander operate as normal, the air that dust suction fan blade 4 rotates the centre of gyration part that makes dust suction fan blade 4 is forced to discharge and forms local low pressure, the dust that sander work produces enters in the sander by dust suction through hole 9 on the liner 8 and the dust absorption passage 10 on the base plate 5 under the atmospheric effect in the external world successively
The wind loop 2 that is positioned dust suction fan blade 4 belows effectively raises dust suction fan blade 4 and rotates the intensity that forms inside air-flow, has improved the effect of dust suction.Dust-blocking ring 1 blocks the gap between base plate 5 and the casing 3, because it is the wool material, careful wool closely can effectively block dust, stops dust to overflow.Simultaneously, because dust-blocking ring 1 has good elasticity, and the wool surface has good flexibility, can not produce excessive friction when making base plate 5 with respect to casing 3 parallel swings, the normal operating efficiency of assurance sander.Dust along cavity between base plate 5 and the casing 3, enters in the bag dust filter that is arranged on dust discharge passage 7 one ends by the dust discharge passage 7 that is arranged on the casing 3 after entering in the sander at last.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
