Detailed Description

The present invention is further illustrated by the following examples, which are only a part of the examples of the present invention, and these examples are only for explaining the present invention and do not limit the scope of the present invention.

As shown in fig. 1 and 2, an infrared thermometer includes an upper casing 1, a lower casing 2, a face cover 5, an LED indicator lamp 3 and an infrared sensor 4, where the upper casing 1 is provided with a first mounting groove 11 and a second mounting groove 12, the bottom of the first mounting groove 11 is parallel to the bottom of the second mounting groove 12, the LED indicator lamp 3 is mounted in the first mounting groove 11, the infrared sensor 4 is mounted in the second mounting groove 12, the LED indicator lamp 3 is located right above the infrared sensor 4, so that light emitted by the LED indicator lamp is horizontally parallel to infrared light emitted by the infrared sensor during measurement, the face cover 5 covers the LED indicator lamp and the infrared sensor and is fixedly connected to the upper casing 1, and the upper casing 1 is fixedly connected to the lower casing 2. The LED indicating lamp and the infrared sensor are mounted on the upper shell, light emitted by the LED indicating lamp is horizontally parallel to infrared light emitted by the infrared sensor during measurement, and when the infrared thermometer is used, the light emitted by the LED indicating lamp is emitted within an actual measurement position range, so that a measurement result of the infrared thermometer can be ensured to be correct. By checking the position of the light point emitted by the LED indicating lamp, whether the actual measurement result is correct or not can be known. The first mounting groove is in contact with the second mounting groove, so that the mounting distance between the LED indicating lamp and the infrared sensor is small, and the light ray position of the LED indicating lamp can be ensured to be a measuring point of the infrared sensor.

Further, the LED lamp also comprises a convex lens 7, wherein the convex lens 7 is arranged right in front of the LED indicating lamp 3, so that light rays emitted by the LED indicating lamp form a beam of light rays parallel to the infrared measuring direction of the infrared sensor after passing through the convex lens.

Install pilot lamp mounting panel 6 on the epitheca 1, LED pilot lamp 3 is installed and is fixed on pilot lamp mounting panel 6, and pilot lamp mounting panel 6 passes through the screw fixation on epitheca 1, and convex lens 7 shroud is in the top of LED pilot lamp 3, makes the LED pilot lamp see through convex lens and shines to the measuring point.

As shown in fig. 4, a layer of stickers 71 with patterns is stuck on the outer surface of the convex lens 7, and the stickers can be designed into different patterns according to the requirements, so that the stickers can project different patterns by irradiating through the indicator lamp, thereby increasing the interest of the product.
