Description

Technical Field

[0001] The utility model relates to an interactive learning device, in particular to an 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 achieve many 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 an open structure. Its principle is to make the light diffuse in the cavity by adding a light guide structure to the LED light source to supplement the light for the sensor. In order to maximize the sampling efficiency, the sensor is usually in a deeper position in the cavity. The small-diameter open structure, together with the light supplement cavity and the sensor in the deep cavity, causes external dust and water vapor to easily accumulate inside the cavity and cannot be cleaned. Over time, it will have an adverse impact on internal sensors, etc., resulting in reduced accuracy and shortened service life of the device. In order to prevent dust and water vapor from entering the sensor and affecting its performance, it is necessary to seal the sensor itself or its cavity. However, the sensor is an important functional component of the intelligent point reading device. The simple sealing means adopted in the prior art will induce the problem of infrared reflection, which will in turn affect its sampling and recognition function and reduce the quality of the device. Summary 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. On the premise of ensuring the sampling and recognition function of the sensor, the sensor itself is sealed to prevent dust and water vapor from entering the interior of the point reading device and affecting the working performance of the components.
