Cooling lawn mower

Abstract

The invention discloses a cooling lawn mower. The cooling lawn mower comprises a main shell, the main shell is provided with a cutting cavity and a motor fan cover, a motor fan cavity is formed in themotor fan cover, a motor is connected in the motor fan cover, fan blades are connected to an output shaft of the motor, a base and a power supply device are connected to the motor fan cover, a firstcooling cavity is formed between the base and the power supply device, a circuit board is arranged in the first cooling cavity, and the base is provided with a plurality of first air holes and secondair holes. According to the cooling lawn mower, the first cooling cavity, the motor fan cavity and the cutting cavity form a cooling channel through the second air holes and the motor fan cover, the fan blades conduct air extraction on the cooling channel, and air enters the cooling channel from the first air holes to cool all components and then is discharged; the cooling effect is good, it is unnecessary to independently arrange cooling devices nearby the components, the size of the cooling lawn mower is reduced, and the production cost of the cooling lawn mower is reduced.

Description

technical field [0001] The invention belongs to the field of lawnmowers, in particular to a heat dissipation lawnmower. Background technique [0002] At present, in order to make the battery pack and the circuit board dustproof and waterproof, the electric lawn mower usually needs to install a protective cover on the top of the battery pack and the circuit board to protect the components. However, the electric lawn mower is working. Battery packs, circuit boards, and motors will generate a lot of heat, which will accumulate in the protective cover. If the heat accumulates for a long time, it will cause abnormalities in electronic components such as battery packs. Working in an abnormal environment for a long time will reduce the service life of the motor. [0003] In order to dissipate heat, the existing electric lawn mowers install a heat sink near each electronic component that needs heat dissipation. Too many heat sinks will increase the production cost of the electric la...

Problems solved by technology

[0002] At present, in order to make the battery pack and circuit board dustproof and waterproof, electric lawn mowers usually need to set a protective cover on the top of the battery pack and circuit board to protect the components. However, when the electric lawn mower is working, Battery packs, circuit boards and motors will generate a lot of heat, which will accumulate in the protective cover. If the heat accumulates for a long time, it will cause abnormalities in electronic components such as battery packs. Working in an abnormal environment for a long time will reduce the service life of the motor.

[0003] In order to dissipate heat, the existing electric lawn mowers install a heat sink near each electronic component that needs heat dissipation. Too many heat sinks will increase the production cost of the electric lawn mower, and at the same time, too many heat sinks will increase the The size of the lawn mower makes the electric lawn mower heavy and inconvenient to use
