[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods and examples. The purpose of providing the examples is only for illustration, and no limitation is imposed. In addition, the spatial orientation words such as "upper", "lower", "left", "right", "top", and "bottom" used in the description of the technical solution of the present invention are convenient for describing the relative position relationship between the components of the product, and do not mean that the product has only the orientation shown in the figure. In actual use, as the orientation of the product is different, the spatial related descriptions used to describe its orientation should also be interpreted in a similar way. In addition, the terms "first" and "second" are only used to distinguish components. It should be understood that these components should not be limited by such terms. They themselves do not mean that these elements have the aforementioned ordinal numbers, nor do they represent the arrangement order of a certain component and another component or the order of the manufacturing method.

[0023] The utility model provides a text scanning error correction teaching pen, which looks like a common writing pen, and has the functions of writing and scanning and displaying error correction information. The text scanning error correction teaching pen includes: a pen body, a wireless communication module, a power module, a display screen module, an optical scanning sensor, a button module and a writing pen module; wherein the display screen module includes a display screen and a display control circuit.

[0024] Specifically, the display screen module, the optical scanning sensor, and the button module are all connected to the wireless communication module. This embodiment uses an ultra-high sensitivity optical scanning sensor to scan the text, which can accurately capture every stroke detail of the writing, obtain a clear scanned image, and then transmit the scanned image to the wireless communication module. The wireless communication module sends the scanned image to an external server, performs image processing and analysis on the scanned image on the server side, and then performs text error correction and generates error correction information, which is transmitted back to the text scanning error correction teaching pen in a language recognizable by the display screen module. After being received by the wireless communication module, it is transmitted to the display screen module for display, such as displaying error-correct word pairs. Due to the use of a highly sensitive optical scanning sensor, a reliable data basis is provided for the server to perform accurate proofreading. It should be understood that the optical scanning sensor used in the embodiment of the utility model is a ready-made product. This optical scanning sensor integrates an optical system, a CMOS sensor, and an image processor. It can output a clear scanned image for use by scanning with a lateral movement. Its internal structure and principle will not be repeated.

[0025] It should be understood that how the server performs image processing, how to perform text correction based on the processed information, and how to generate a language recognizable by the display screen module from the correction results do not fall within the scope of the text scanning and correction teaching pen of the present invention, and can all be achieved using existing technologies, and the present invention does not impose any restrictions on this.

[0026] The display module includes a display screen and its matching display control circuit. The display screen is embedded in the middle of the pen body, and the display control circuit is built into the pen body, close to the back of the display screen. Figure 3 , the display control circuit is also connected to the wireless communication module and the key module. The information received by the wireless communication module is transmitted to the display control circuit and then displayed on the display screen. The display control circuit is a supporting circuit of the display screen. The display screen module formed by the two is a ready-made technology, so the specific circuit structure of the display control circuit is not repeated. The key module is connected to the display screen and the display control circuit at the same time, so that the display and page turning of the display screen can be operated through the key module. In some embodiments, the display screen 4 is a touch display screen; in other embodiments, the display screen 4 is a non-touch display screen. In addition to the basic power button, the key module may also include a display screen operation button, which is connected to the display screen module. Through the display screen operation button, interactive operations on the display screen such as up / down, left / right page turning, lighting / extinguishing the display screen, etc. are realized.

[0027] In some embodiments, the wireless communication module may be a Bluetooth module, and the connection with the external server is realized by Bluetooth pairing. In such an embodiment, the power button is connected to the power module and the wireless communication module at the same time, and a single click of the power button realizes power on / off, and a long press of the power button realizes Bluetooth pairing; or, the button module may also include a network pairing button, wherein the power button is connected to the power module to realize power on / off of the text scanning error correction teaching pen, and the network pairing button is connected to the Bluetooth module to realize Bluetooth pairing.

[0028] In some embodiments, the wireless communication module can be WiFi communication, and WiFi connection is achieved by operating the touch display screen or pressing buttons on the non-touch display screen; alternatively, a network configuration QR code is set on the pen body, and the user can scan the QR code to connect the text scanning and error correction teaching pen to the WiFi network, thereby achieving communication with an external server.

[0029] In some embodiments, the power module includes a battery and a power management circuit. The power management circuit may adopt a known circuit structure, and its main purpose is to optimize battery charge / discharge management, improve battery efficiency, and extend battery life. In a preferred embodiment, a magnetic charging base compatible with the power module may also be provided. The power module of the text scanning and error correction teaching pen may be brought close to the magnetic charging base to be attracted for wireless charging. To achieve magnetic charging, Figure 2 The power module of this embodiment may further include a magnetic part, a magnetoelectric conversion device and a rectifier. The magnetic part such as a magnet is used to adsorb the magnetic charging base; the main function of the magnetoelectric conversion device is to convert magnetic energy into electrical energy using the principle of electromagnetic induction, which is usually composed of one or more coils. When the magnet adsorbs the energized magnetic charging base, an induced current can be generated in the coil close to the magnet; the rectifier is connected between the magnetoelectric conversion device and the battery, and is used to convert the alternating current generated by the magnetoelectric conversion device into direct current and provide it to the battery.

[0030] In some embodiments, the text scanning and error correction teaching pen of the utility model can also quickly save the paper text after error correction in electronic form to other electronic devices. The specific implementation method is: setting a Type-C interface and a memory, the Type-C interface is connected to the memory, the memory is connected to the optical scanning sensor, the optical scanning sensor scans the text to obtain a scanned image which can be temporarily stored in the memory, and the required text image can be exported to a computing device (such as a tablet computer, a laptop computer, a desktop computer, etc.) by connecting a data cable through the Type-C interface. In addition, the Type-C interface can also be connected to a power module to provide wired fast charging.

[0031] The text scanning error correction teaching pen provided by the embodiment of the utility model can especially improve the use experience of paper writing / reading. Specifically: the user can use the writing pen head provided by the user to write, and in the writing process, for example, each time a paragraph is written, the user turns around and scans the written content with the optical scanning sensor at the other end, and provides the written text in electronic form to an external server for text error correction, and displays the error correction result through the display module, so that the user can write and check at the same time, and timely obtain the error information of the text writing, and correct it in time. Finally, the satisfactory text after error correction can be scanned and saved to other devices through the Type-C interface. In order to avoid the device from transmitting the scanned image to the server for error correction during the process of scanning and correcting the text, the key module can further include an error correction switch button, which is used to control whether the data path between the wireless communication module and the optical scanning sensor is connected or not. When the error correction switch button is operated to cut off the data path between the wireless communication module and the optical scanning sensor, the scanned text will no longer be transmitted to the server for error correction, and the user can then implement the saving operation of the corrected text.

[0032] It should be understood that the text scanning and error correction teaching pen of the present invention is not limited to paper texts. By replacing the paper writing pen head with a capacitive pen, it is also applicable to the scanning of electronic texts such as electronic writing boards. The capacitive pen can be fixedly set on the pen body, and the paper writing pen head is preferably connected to the end of the pen body in a detachable manner, so that it can be replaced after use.

[0033] In addition, since the processing of the scanned image and the error correction of the processed text information in the utility model are not performed in the text scanning error correction teaching pen terminal, but are handled by an external server, there is no need to place a complex data processing module inside the pen body, so that the text scanning error correction teaching pen of the utility model can have a smaller and more delicate pen body, which is easy to carry and hold; the pen body can be designed into a cylindrical or triangular prism shape to adapt to the usage habits of different users. Furthermore, in order to avoid grip discomfort caused by long-term use, the ergonomic optimization design can also be performed on the pen body gripping part, such as a concave arc design that adapts to the fingers.

[0034] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For technicians in the technical field to which the present invention belongs, several equivalent substitutions or obvious variations can be made without departing from the concept of the present invention, and the performance or use is the same, which should be regarded as belonging to the protection scope of the present invention.
