Abstract
The utility model relates to a grass pruning machine with a rear-mounted motor, which comprises a casing. A motor and a fan are disposed in the casing, the motor is provided with an output shaft, the fan is mounted on the output shaft of the motor, a volute is formed in the casing, and the fan is enclosed in the volute which adopts the output shaft of the motor as a center. The grass pruning machine can effectively increase air outlet effect, obviously reduces temperature of the motor, and increases radiating effect.
Description
Technical field
The utility model relates to electric tool, relates in particular to a kind of rearmounted motor mower.
Background technology
In view of the rearmounted motor mower of selling on the market, the power of motor has all surpassed 1000W, power is big more, and to bring problem be exactly that the temperature rise of motor is high more, this just requires that there is higher requirement in the air channel of the casing of rearmounted motor mower, and prior art substantially all adopts at the two ends of motor and has air inlet and air outlet, adopts traditional air channel, air-out effect is poor, and its radiating effect is not obvious, and air-out effect is poor, causes motor temperature can not fall.
The utility model content
The technical problems to be solved in the utility model is: a kind of rapid heat dissipation, rearmounted motor mower that air-out efficient is high are provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of rearmounted motor mower, comprise housing, be provided with motor and fan in the housing, this motor has output shaft, described fan is installed on the motor output shaft, is formed with spiral case in the described housing, and it is in the spiral case at center that described fan is enclosed in described motor output shaft.
According to another embodiment of the present utility model, rearmounted motor mower comprises that further described housing is provided with air inlet and air outlet, described motor is between air inlet and air outlet, be formed with the air channel between described air inlet and the described air outlet, described air outlet is positioned at the opening part of spiral case.
According to another embodiment of the present utility model, rearmounted motor mower comprises that further the direction of described air outlet is perpendicular to ground surface.
According to another embodiment of the present utility model, rearmounted motor mower comprises that further it is in the spiral case of equal angles spiral at center that described fan is enclosed in described motor output shaft.
According to another embodiment of the present utility model, rearmounted motor mower comprises that further described fan is a centrifugal fan.
The utility model has solved the defective that exists in the background technology, can effectively improve air-out effect by the utility model, obviously reduces motor temperature, improves radiating effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the part-structure schematic diagram of the utility model preferred embodiment;
Fig. 3 is the cross-sectional schematic of spiral case part among Fig. 1;
Wherein: 1, housing, 11, spiral case, 13, air inlet, 15, air outlet, 17, the air channel, 3, motor, 31, output shaft, 5, fan.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-3, a kind of rearmounted motor mower, comprise housing 1, be provided with motor 3 and fan 5 in the housing 1, this motor 3 has output shaft 31, described fan 5 is installed on motor 3 output shafts 31, is formed with spiral case 11 in the described housing 1, and it is in the spiral case 11 at center that described fan 5 is enclosed in described motor 3 output shafts 31.Effectively improve housing 1 air-out efficient by spiral case 11, reduced the temperature of motor 3 in the housing 1.And in the spiral case 11 of the equal angles spiral that it is the center that described fan 5 is preferably enclosed in described motor 3 output shafts 31.
Wherein, described housing 1 is provided with air inlet 13 and air outlet 15, and described motor 3 is formed with air channel 17 between described air inlet 13 and the described air outlet 15 between air inlet 13 and air outlet 15, and described air outlet 15 is positioned at the opening part of spiral case 11.In addition, fan 5 is a centrifugal fan.By spiral case 11 wind of air inlet 13 17 is directed to air outlet 15 along the air channel, has improved the flow velocity of wind, make motor 3 cool off fast.
Because the distinguished and admirable speed of air outlet 15 is very fast, when air outlet 15 comes out, may damage the user, so the direction of the preferred described air outlet 15 of the utility model is perpendicular to ground surface as foreign material.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
