Description

Technical Field

[0001] The present invention relates to a handheld electric appliance, in particular to a hair care appliance, such as a hair dryer, a curling iron, a hair straightener and the like and an external control device thereof. Background Art

[0002] In the prior art, the PCB control board and control buttons of handheld electrical appliances such as hair dryers, curling irons, and hair straighteners are all arranged on the electrical appliance body. As a result, when the user is using the handheld electrical appliance, the user cannot directly observe the buttons and can only press them blindly based on their impressions. This is applicable when the button functions are relatively simple. However, when the handheld electrical appliance has many button functions and is arranged at different positions on the electrical appliance body, the user can only suspend the use and then perform the corresponding operation after seeing the position of the buttons clearly, which brings a lot of inconvenience to the user.

[0003] Meanwhile, most of the existing handheld electrical appliances are left alone when not in use. Although some manufacturers have designed supporting stands to match the handheld electrical appliances in response to this problem, the supporting stands only have supporting or storing functions, and do not have the functions of controlling or acting as a power socket, and thus have only a single function.
