Embodiment Construction

[0009] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0010] figure 1 The human body position sensing electric fan shown is composed of a fan blade 1 , two infrared heat source probes 2 , a motor 3 , a main control panel 4 , and a bracket 5 . One of the infrared heat source probes 2 is located directly in front of the fan blade 1, which can detect the position of the human body to determine whether there is a human body in the wind direction, and at the same time judge the function correspondence between the wind speed and the alignment time according to the temperature The relationship can be adjusted by buttons on the main control panel 4. There is also an infrared heat source probe 2 on the main control panel 4. This wide-angle infrared heat source probe 2 can determine the distribution of human body heat sources in the room, so as to determine the magnitude of the fan's rotation, and increase ...

Abstract

The invention discloses a human body position sensing electric fan which consists of fan blades (1), two infrared heat source probes (2), a motor (3), a master control panel (4) and a bracket (5), wherein one infrared heat source probe (2) is positioned in right front of the fan blades (1) and can be used for sensing the position of a human body so as to determine whether a human body exists in the wind direction or not; and meanwhile, the grade of the wind speed and the aligning time can be judged according to the magnitude of the temperature; the other infrared heat source probe (2) is arranged on the master control panel; and the infrared heat source probe (2) with a wide angle can be used for determining the distribution of a heat source in a room so as to decide the amplitude of a fan rotating head. Therefore, according to the human body position sensing electric fan disclosed by the invention, the wind sweeping range can be determined according to the existing position of the human body; and meanwhile, the wind force is increased for the direction in which persons exist, and the wind force is reduced in the direction in which no person exists so as to save energy sources.

Description

technical field [0001] The invention relates to a human body position induction electric fan, in particular to a human body position induction electric fan which determines the position of the human body through a heat source so as to stay for a longer time in the state of shaking the head. Background technique [0002] In the hot summer, the electric fan is cool. However, in the state of shaking the head, people often feel that the residence time is too short, and they are removed without cooling down. The existing electric fans have a fixed speed and range of rotation, and lack of flexibility. And blowing directly to it can easily cause diseases such as colds. In order to achieve coordination in the middle, the electric fan is required to have a certain degree of selectivity for air supply. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art and provide a fan which can determine the range of air supply ...
