Description
Technical Field
The present invention relates to a fan with direction sensing, and more particularly to a fan with direction sensing, which can adjust the operation mode of the fan according to the direction of use.
Background
A heat dissipation fan is usually installed in a conventional electronic device, such as a server, a host of a personal desktop computer, an all-in-one computer (AIO), a notebook computer, a display, etc., and heat generated by the electronic device during operation is dissipated to the outside by an air flow generated by the heat dissipation fan. The conventional single heat dissipation fan only has a single operation function, such as a function of increasing or decreasing the speed of the heat dissipation fan or a function of rotating the heat dissipation fan forward or backward. Therefore, when a user needs the cooling fan with the functions of speed-up and speed-down operation and forward/reverse rotation, the user needs to purchase two cooling fans with different functions to install the cooling fans together, which results in poor convenience and increased use cost. In addition, some electronic devices (such as notebook computers, tablet computers, smart phones or smart watches) have a thin structure, so that the space inside the electronic device is limited, and two cooling fans with different functions cannot be installed at the same time, so that a user must choose one function (such as a lifting operation function, a forward rotation function or a reverse rotation function) and abandon the other function (such as a forward rotation function, a reverse rotation function or a lifting operation function).
Although the manufacturers have developed the heat dissipation fans with two functions to solve the above-mentioned functions of the heat dissipation fan, another problem is that users must go through complicated and tedious steps each time they want to switch the current lifting operation function of the heat dissipation fan to the forward rotation function of another heat dissipation fan, and also have some professional users to switch the functions of the heat dissipation fan, for example, after the professional users spend a long time inputting new instructions (such as forward rotation function instructions) again to the connected heat dissipation fan through an external computer each time, the heat dissipation fan can be switched to the forward rotation function through the instructions inputted by test verification, if the lifting operation function is switched back, another related instruction must be inputted again, and most of the users generally do not know how to change the functions of the heat dissipation fan by inputting instructions to the heat dissipation fan, therefore, the problems of poor convenience in use, failure to switch the fan function immediately and long function switching time are caused.
