Description

Technical Field

[0001] The utility model relates to an interactive learning device, in particular to a dust-proof intelligent point-reading device. Background Art

[0002] An intelligent point-reading device is an intelligent reading and interactive learning tool that combines optical image recognition technology and digital voice technology, and can simultaneously realize functions such as point-reading, repeating, following, recording, and entertainment. The head of the intelligent point-reading device has a recognition window. The head of the traditional point-reading device is of an open structure. Its principle is to make the light diffuse in the cavity to supplement light for the sensor by adding a light guide structure to the LED light source. In order to maximize the sampling efficiency, the sensor is usually at a relatively deep position in the cavity. The small-aperture open structure plus the light-supplementing cavity and the sensor in the deep part of the cavity result in easy accumulation of external dust and water vapor inside the cavity and inability to clean it. Over time, it will have an adverse impact on internal sensors, etc., thereby reducing the accuracy of the device and shortening its service life. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a dust-proof intelligent point-reading device, which seals the cavity where the sensor is located on the premise of ensuring the sampling and recognition function of the sensor, and avoids dust and water vapor from entering the inside of the point-reading device and affecting the working performance of components.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a dust-proof intelligent point-reading device, including a housing, a through hole is provided on the side wall of the housing, an installation chamber is provided inside the housing, an infrared recognition module facing the through hole is provided in the installation chamber, a sleeve is provided between the infrared recognition module and the through hole, an installation hole is provided at one end of the sleeve close to the through hole, and an infrared coating lens is embedded in the installation hole.

[0005] Further, a bracket is provided in the installation chamber, the infrared recognition module and the sleeve are both arranged on the bracket, and the sleeve covers the infrared recognition module.

[0006] Further, the infrared recognition module includes an infrared camera and an infrared LED facing the through hole.

[0007] Further, it further includes a light guide column, the light guide column is arranged between the infrared recognition module and the sleeve, and a camera hole is provided at a position corresponding to the infrared camera on the light guide column.

[0008] Further, an annular positioning groove is provided on the inner wall of the housing around the through hole, and the sleeve abuts against the annular positioning groove.

[0009] Further, an annular sealing groove is provided in the installation hole, and the infrared coating lens is located between the annular positioning groove and the annular sealing groove.

[0010] The beneficial effects of the present utility model are as follows: for the dust-proof intelligent point-reading device, an infrared recognition module and a sleeve are installed inside the housing. The sleeve is provided with an installation hole corresponding to the position of the through hole on the housing, and an infrared coating lens is embedded in the installation hole. The infrared coating lens is a lens with a surface coating. Through coating to increase light transmission, its infrared transmittance reaches more than 98%, enabling most of the infrared light emitted from the front of the light source to penetrate through the lens, reducing infrared light reflection, avoiding the generation of shadows in the recognition image of the infrared recognition module due to the presence of the lens, and ensuring recognition accuracy. The infrared coating lens can also make dust and water vapor fall on its surface, which can both clean the dust and water vapor and enhance the sealing performance of the housing installation chamber, preventing dust and water vapor from entering the inside of the point-reading device and affecting the working performance of the components.
