Abstract
The utility model discloses an electric tool heat radiating system, which comprises a fan, an air inlet and an air outlet at least. Wherein, the air inlet is composed of a water retaining element and the air outlet includes a wind board and an air shield. The wind board top and the air shield top have a curved surface. The waterproof radiating system can reversely discharge water flow and has simple structure and reliable function.
Description
Technical field
The utility model relates to a kind of cooling system that is used for electric tool, especially has the cooling system of water-proof function.
Background technology
For the motor to electric tool dispels the heat, a cover cooling system often is set in electric tool, its cooling system comprises air inlet, fan and air outlet.But traditional cooling system does not have water-proof function or can not satisfy the waterproof demand preferably, when some instrument needs water to come cutter cooled off in cutting process, can cause water to enter electric tool inside, make electric tool can not normally use or cause nonvolatil damage.For example electric tool such as makita 4100NH owing in use can need constantly to carry out water-cooled, is used to cool off its blade and tangent plane, so just is easy to cause water to enter cutting machine inside, thereby has influenced the normal use of cutting machine.Can the situation that water enters motor interior not appear because of sleety weather even do not need to carry out under the situation that the electric tool of water-cooled works out of doors yet.
The utility model content
The purpose of this utility model is to provide a kind of cooling system with water-proof function that is used for electric tool, and simple in structure, reliable in function.
For achieving the above object, the cooling system that is used for electric tool that the utility model disclosed comprises: at least one fan, an air inlet, an air outlet, described air inlet comprises a dash element, described air outlet comprises a wind deflector, a wind scooper, and described wind deflector top and described wind scooper top are curved surface.
The utlity model has following advantage: this cooling system has water-proof function, and can be with the reverse drainage of current, and is simple in structure, reliable in function.
Description of drawings
Below in conjunction with accompanying drawing cooling system of the present utility model is described in further detail, wherein:
Fig. 1 is the stereogram that comprises the electric circular saw of the related cooling system of the embodiment of the utility model first-selection;
Fig. 2 is the explosive view of the electric circular saw among Fig. 1;
Fig. 3 is the cutaway view of the electric circular saw among Fig. 1;
Fig. 4 is the fundamental diagram of the air outlet of the electric circular saw among Fig. 1.
The specific embodiment
As Figure 1-3, the cooling system of electric circular saw 100 comprises a fan 12, one air inlets 1, one air outlet 2, air inlet 1 comprise a dash element 9, and air outlet 2 comprises a wind deflector 5, one wind scooper 6 constitutes the reclinate ventilating duct 20 in end between wind deflector 5 and the wind scooper 6.In the present embodiment, the top 61 of the top 51 of wind deflector 5 and wind scooper 6 is a cambered surface.Sealing ring 4 is sealed in wind deflector 5 and wind scooper 6 between gear-box 3 and the casing 8, and wind deflector 5 is provided with wind-guiding leaf 52, described wind-guiding leaf 52 help air outlet 2 air draft this be one of them embodiment.Air inlet 1 is arranged on hood 10 places of electric circular saw 100, and its dash element 9 is one to have the screen pack of water-proof function, makes water can not enter the internal structure 7 of electric circular saw 100 from air inlet 1.The dash element has in mechanical field very widely to be used, therefore, the filter in the utility model be not limited to mentioned above and accompanying drawing shown in structure, can be other frame modes that the mechanical field technical staff knows fully.
As shown in Figure 4 be the fundamental diagram of the air outlet 2 of electric circular saw 100.When electric circular saw 100 operate as normal, fan is activated the motor 14 that is used for electric circular saw 100 and cools off, thereby hot blast is from discharging between wind deflector 5 and the wind scooper 6.When the air outlet 2, because of the top of wind deflector 5 and wind scooper 6 is cambered surfaces, so it can make current can not enter in the electric circular saw 100 the reverse drainage of current, thereby can not destroy the normal use of machine as current.
For the utility model, the top of wind deflector 5 and wind scooper 6 is that cambered surface is a kind of optimal way of the present utility model.The utility model also can wind deflector 5 and the top of wind scooper 6 be set to other curved surface, such structure can reach the purpose of this utility model equally, protected by the utility model.
The utility model is not limited to the above-mentioned specific embodiment.Those of ordinary skill in the art can understand at an easy rate that under the prerequisite that does not break away from the utility model principle and category, bracing frame regulating system of the present utility model also has a lot of the modification and alternate embodiments.Protection domain of the present utility model is determined by claim.
Claims (4)
