Abstract: An electric tool includes an output member, a motor, and a housing. The motor includes a rotor shaft, a rotor core, and a stator component. The rotor shaft is configured to rotate around a first axis. The stator component includes a coil winding. The stator component surrounds the first axis to separate the accommodation cavity into a first space and a second space. The first space includes a first end and a second end. The motor further includes a first end cover and a second end cover. The first end cover is disposed at the first end of the first space. The second end cover is disposed at the second end of the first space. A passage is formed between the second end cover and a structure surrounding the first space, and the passage is configured to place the first space into communication with the second space.

Abstract: A dish washing device includes an inner compartment and a water collection cup arranged at a bottom part of the inner compartment, a wash pump and a heating apparatus are arranged on the water collection cup and/or a first water supply pipeline. The wash pump is used for pumping washing water inside the water collection cup to the inner compartment via the first water supply pipeline, and the heating apparatus is used for selectively heating the washing water. The heating apparatus includes a thermoelectric cooler used for heating the washing water. In comparison to heating washing water using an electric heater, thermo- electric cooler may save a large amount of power, thereby reducing the power consumption of the dishwashing device, and facilitating energy conservation and eco-friendliness.

Abstract: A power tool includes a main body and a battery pack. The main body includes a housing and a motor, a switch assembly, and an electronic control device. The electronic control device is electrically connected to the switch assembly and the motor. The electronic control device includes an electronic control assembly, a mounting base, and a connecting assembly. The electronic control assembly includes a power circuit board. The power circuit board is provided with an opening. The connecting assembly conductively connects the battery pack to the electronic control assembly, connects to the mounting base via the opening, and mates with the mounting base to form a mounting space in which the electronic control assembly is mounted.
