Embodiment
Below in conjunction with the accompanying drawings, the better embodiment of power-operated mower is illustrated.
Please refer to Fig.1 to Fig. 4, disclose a kind of power-operated mower 100, including housing 110, on housing 110
A pair of of front walking wheel 120 and a pair of of rear walking wheel 130, the operation lever 140 on housing 110, on housing 110
Driving motor 150 and the cutting blade 160 driven by driving motor 150.
Supporting item 112 is equipped with housing 110, which is provided with opening 1122.Driving motor 150 bears against and is fixed on supporting item
On 112, have through the extending portion 152 of opening 1122.In this way, supporting item 112 and driving motor 150 are jointly in housing 110
A cutting chamber 114 is isolated, and drives the extending portion 152 of motor 150 to extend into cutting chamber 114, and drives motor 150
Other parts are then positioned at 114 top of cutting chamber.
Drive motor 150 that there is the output shaft 154 for the bottom for stretching out foregoing extending portion 152, for installing and driving cutting
Blade 160 carries out cutting operation.Cutting blade 160 is fixed on output shaft 154, is passed through under the drive of output shaft 154 at a high speed
The purpose of grass is cut in rotation to reach.
Front walking wheel 120 and rear walking wheel 130 make power-operated mower 100 have good mobility.Operation lever 140 is to supply
Operator is hand steered to carry out the element of operation mowing, drives the brake control of the controlling switch of motor 150, front walking wheel and rear walking wheel
System processed can be arranged in operation lever 140, and such operator may not necessarily bend over when operating power-operated mower 100, symbol
Close ergonomics.
In order to clean cutting 114 inner wall of chamber and cutting blade 160, cut in chamber 114 and be also equipped with for cleaning cutter
The nozzle 170 of piece 160 and cutting 114 inner wall of chamber.When needing cleaning, it is only necessary to connect water source, nozzle 170 is sprayed water.Spray
First 170 is generally cylindrical, and axial parallel to driving motor 150 is set, and is fixed on housing 110, and its one end extends housing
To be connected with water source outside 110.But it may be noted that there is no restriction for the shape of nozzle 170, the injector head that can carry out water spray operation is equal
It can be used.
Power-operated mower 100 further includes the water pipe 180 outside housing 110, which is connected with nozzle 170.This
Place, water pipe 180 is connected on nozzle 170, is as 100 1 annexes of power-operated mower, when use only needs directly to connect
I.e., without interim water pipe is found in water source.Water pipe 180 preferably using hose, so when not in use water pipe 180 can coil it is agglomerating
Shape, is then attached on housing 110, facilitates 100 normal operation of power-operated mower and transfer transport.Certainly, power-operated mower 100
On can be not provided with water pipe, it is ensured that 100 terminal with compact integral structure of power-operated mower is, it is necessary to interim mating when using water pipe.
Please refer to Fig.3, the top of driving motor 150 offers the air inlet 156 for radiating, and drives motor 150
The equal sealed set in bottom and side of extending portion 152, namely there is no thermovent on bottom and side.In this way, nozzle 170 is being cut
When water spray carries out cleaning operation in chamber 114, water will not enter inside driving motor 150 from extending portion 152.Meanwhile air inlet
156 outside cutting chamber 114, therefore on the one hand can ensure to drive the heat dissipation of motor 150, and on the other hand therefore water will not be from inlet air
Mouth 156 enters inside driving motor 150.
Nozzle 170 is placed in the side of the extending portion 152 of driving motor 150, the axial direction of its water spraying direction and driving motor 150
It is intersecting.In the present embodiment, the water spraying direction of nozzle 170 is perpendicular to the axial direction of driving motor 150.Further, nozzle 170
Water spraying direction be face driving motor 150 so that nozzle 170 spray water when, water be first be sprayed onto driving motor 150 extending portion
On 152 side, then a part of water can be splashed on cutting 114 inner wall of chamber and carry out cleaning work, and another part water can fall
Cleared up on to cutting blade 160.In the process, since the high speed of cutting blade 160 rotates, cutting blade 160 can also
Constantly water is thrown away, cutting 114 inner wall of chamber can thus be cleared up.It is noted that the water spraying direction of nozzle 170
Driving motor 150 can be deviated from, such water will be first ejected on 110 inner wall of housing, and cutting 114 inner wall of chamber is cleared up, from
The cleaning to cutting blade 160 can be completed after being splashed down on cutting 114 inner wall of chamber.
In addition, vertical situation is not limited between axial direction of the water spraying direction of nozzle 170 with driving motor 150, can also
It is axial direction of the water spraying direction parallel to driving motor 150 of any angle or nozzle 170.The water spraying direction of nozzle 170
During parallel to the axial direction for driving motor 150, the water spraying direction of nozzle 170 can vertically upward, can also be vertically upward.In a word
Come, position of the nozzle 170 in cutting chamber 114 is not especially limited, and the water of ejection can be penetrated any direction in housing 110
Go out, the cleaning that can reach desired was thought.In addition, one or more water outlets can be set on nozzle 170, multiple water outlets
Mouth can arbitrarily be set as needed, for example, multiple water outlets can be evenly distributed or multiple along the axial direction of driving motor 150
Water outlet is evenly arranged in the circumferential direction of nozzle 170.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
