[0092] Compared with the first embodiment, the axial length of the fully extended heat conduction member 120 and its heat conduction portion 102a in this embodiment is longer in the axial direction, so more heat can be conducted into the airflow channel 105, The heat is dissipated by the circulating airflow in the airflow channel 105 . The bracket tooth gap 1025 of the insulating bracket 1024 in this embodiment is the same as the structure and position in the aforementioned first embodiment, and will not be repeated here.

[0093] Compared with the first embodiment and the second embodiment, the heat conduction element 120 in this embodiment fully extends to the entire inner cavity of the motor in the axial direction, and the heat conduction material part of the heat conduction element 120 is longer in the axial direction. , so more heat can be conducted to the airflow channel 105 , and the air flow in the airflow channel 105 can be used for heat dissipation.

Abstract

The invention discloses a garden tool, comprising: a housing, a tool accessory, an output shaft, a motor and an airflow passage, wherein the housing includes an air inlet and an air outlet, and the airflow passage is formed between the air inlet and the air outlet The motor includes a motor shaft, a stator and a rotor; the electric tool also includes a heat conduction element, which is arranged between the rotor and the stator to conduct heat between the rotor and the stator into the airflow channel. The invention also provides a hair dryer. The electric tool of the present invention conducts the heat inside the motor to the airflow channel through the heat conducting member, and utilizes the circulating airflow in the airflow channel to dissipate heat from the motor, thereby improving the heat dissipation efficiency of the motor and effectively protecting the motor.

Description

technical field [0001] The invention relates to the field of garden tools, in particular to a hair dryer. Background technique [0002] For some existing electric tools, there is a lot of dust or metal debris in the use environment, which is easy to affect the use of electric tools, such as angle grinders, sanders and other grinding tools, hair dryers and other garden tools. [0003] Taking a blower as an example, the blower is a garden tool that can be operated by a user to blow grass clippings, leaves, etc. to clean the yard or garden. The blower is provided with an air inlet and an air outlet, and the fan is driven by the motor to generate a blowing air flow, thereby cleaning fallen leaves and debris in the courtyard or garden. [0004] When the hair dryer is working, the environment where dust, debris or fine particles are relatively large, in order to prevent the debris scattered in the space from entering the housing of the hair dryer through the air inlet at the same...
