Problems solved by technology
However, the above-mentioned cooling technology has the following problems: the utilization rate of the cooling air is low, and the cooling effect of the battery pack is generally not good. As a result, the power supply cannot be normal, so that the lawn mower stops working; in addition, the poor cooling effect of the battery pack will also lead to problems such as short battery cycle life and low capacity utilization, which will not only increase the cost of use, but also reduce work efficiency
[0003] Therefore, how to avoid affecting the normal use of the lawn mower due to the poor cooling effect of the battery pack is a technical problem that those skilled in the art need to solve at present.

The invention discloses an electric lawnmower, which has a power head, and the power head includes a housing, at least one battery pack and a motor are arranged inside the housing; any battery pack is provided with several battery pack air inlets, and the housing There is a first air inlet corresponding to the air inlets of all the battery packs for the cooling air to enter the casing, and there is a gap between any battery pack air inlet and its corresponding first air inlet to guide the external cooling air into the casing. The air duct in the battery pack, the bottom of any battery pack is provided with a battery pack air outlet for the cooling air after cooling the batteries in the battery pack to flow to the motor. The above-mentioned electric lawn mower can greatly improve the cooling effect of the battery pack, and at the same time improve the utilization rate of the cooling air, so as to solve the problem in the prior art that the lawn mower is shut down due to over-temperature protection when the ambient temperature is high. The setting method can improve the working efficiency of the lawn mower, prolong the cycle life of the battery cell and increase the capacity utilization rate of the battery cell.
Description
technical field [0001] The invention relates to the technical field of gardening tools, in particular to an electric lawnmower. Background technique [0002] In the electric lawn mowers of the prior art, for the cooling of the key components involved in the power head, that is, the battery pack, the controller and the mowing motor, most of them adopt the scheme of adding an impeller at the output end of the mowing motor. , The adsorption force generated by the impeller and the cutting blade draws the cooling air from the air inlet, and then flows through the surface of the battery pack, controller and mowing motor, and achieves the cooling effect by taking away the heat dissipated. However, the above-mentioned cooling technology has the following problems: the utilization rate of the cooling air is low, and the cooling effect of the battery pack is generally not good. As a result, the power supply cannot be normal, so that the lawn mower stops working; in addition, the poor...
