Description

Technical Field

[0001] The utility model relates to the technical field of infrared temperature measuring equipment, in particular to a laser display integrated infrared temperature measuring device. Background Art

[0002] Traditional laser infrared temperature measuring devices usually include an infrared temperature measuring head, a laser transmitting head and a translucent reflective sheet. The laser transmitting head and the infrared temperature measuring head are respectively facing the two sides of the translucent reflective sheet. The laser can be reflected on the reflective sheet, and the infrared can pass through the reflective sheet and be captured by the infrared temperature measuring head, so that the trajectory of the laser and the trajectory of the infrared are coaxial. The laser can be projected at the temperature measurement point, and the user can know the temperature measurement position at this time.

[0003] However, the above structure is only for single-point temperature measurement. As users' requirements increase, users need to measure the temperature of a certain area of ​​an object. Therefore, multiple infrared temperature measuring heads need to be configured to collect the temperatures of different points in the area respectively. The laser transmitter head can only form a single-point projection, and users cannot accurately know the area where the temperature is detected. If a diffuse lens is used to disperse the laser projection to the temperature measurement area, the pixel is low, which affects the visual experience. If multiple laser transmitter heads are used, heat will be generated during operation, affecting the accuracy of the infrared temperature measuring head detection. Utility Model Content
