Technical Field

[0001] The utility model belongs to the technical field of invoice issuance and printing, and specifically relates to a mobile invoicing handheld device equipped with a solar charging panel. Background Art

[0002] A mobile invoicing handheld device equipped with a solar charging panel combines portability and environmentally friendly energy utilization, aiming to solve the charging problem of traditional invoicing devices when used outdoors or in environments with unstable power supply. By integrating a solar charging panel, the device can automatically charge under light conditions, extend the use time, reduce dependence on external power sources, improve the device's endurance and operational flexibility, and is particularly suitable for outdoor sales, mobile services, and field office scenarios.

[0003] The existing VAT special invoice self-service invoicing machine (Announcement No.: CN207149012U) generally has the following problems in use:

[0004] 1. When charging is not possible when going out for invoicing, insufficient power will affect the efficiency of invoicing: The soil is too dry: Invoicing interruption: Insufficient power will cause the device to suddenly shut down or fail to operate normally, directly interrupting the invoicing process, and unable to provide invoices to customers in a timely manner, affecting customer experience and satisfaction. Reduced work efficiency: Frequent device shutdown and restart will waste time, reduce invoicing work efficiency, prolong customer waiting time, and reduce service quality, so a mobile invoicing handheld device equipped with a solar charging panel is urgently needed.

[0005] 2. Inability to upload invoicing data in real time, inconvenient to backtrack when invoicing errors occur: Data loss: If the device fails or runs out of power, the data that has not been uploaded may be lost, resulting in the inability to backtrack and restore the original invoicing information, affecting the integrity of financial records. Difficulty in correcting errors: Due to the inability to backtrack and check invoicing records in real time, invoicing errors may not be discovered for a long time, and the correction process is complicated and time-consuming, increasing the workload and the difficulty of error correction. Therefore, there is an urgent need for a mobile invoicing handheld device that can upload invoicing data in real time.

[0006] 3. When the invoice paper is used up, it is inconvenient to replace it: Poor customer experience: Failure to provide invoices to customers in a timely manner will lead to longer waiting time for customers, a worse experience, and may cause customer dissatisfaction and damage the company's reputation. Reduced business efficiency: Frequently dealing with the problem of running out of invoice paper, especially when the replacement process is cumbersome, will greatly reduce the efficiency of invoicing and service, and affect the smoothness of the work process. Therefore, there is an urgent need for a mobile invoicing handheld device that is convenient for replacing invoice paper. Utility Model Content

[0039] Detailed description of the equipment operation process

[0040] This embodiment describes in detail the operation process of a mobile invoicing handheld device that integrates multiple advanced technologies, from startup to completion of a series of operations for invoicing, to ensure efficient and convenient use of the device.

[0041] 1. Equipment startup: The operator presses the power button of the equipment, and the equipment switches from standby mode to working mode. After the built-in electronic board receives the power signal, it starts all functional modules of the equipment. The data display screen lights up, showing the startup interface and operation prompts.

[0042] 2. Data input: The operator enters the relevant information required for invoicing, such as customer information, product or service details, quantity and amount, etc. through the data input button. The location and design of the data input button make the operation simple and fast. The input information is displayed in real time on the data display screen, which is convenient for the operator to confirm the correctness of the input.

[0043] 3. Data verification and confirmation: After the operator confirms that all the input data is correct, he / she submits the data by pressing the confirmation button. The submitted data is transmitted to the electronic board for processing and storage. At the same time, the remote data transmission module starts working and uploads the invoicing data to the backend server or cloud in real time to ensure the security and traceability of the data.

[0044] 4. Invoicing and printing: After the electronic board processes the data, it instructs the printing module to start printing the invoice. The printing module uses the MP-B20 thermal printer module from Seiko Instruments to ensure fast and clear printing. The invoice paper enters the printing module from the storage bin through the invoice paper fixing rod for printing. The invoice paper rotation motor uses the 24H670S stepper motor from Nidec Corporation to ensure accurate positioning and stable rotation of the invoice paper during the printing process. After printing, the invoice is smoothly output from the ticket outlet at the front end of the invoice paper storage bin.

[0045] 5. Paper replenishment: When the device detects that the paper is running out, it will prompt the operator to replace the paper through the data display screen. The operator presses the storage cover and uses the cover insertion connection to open the cover. Put the new paper roll into the storage bin and fix it on the paper fixing rod. After the cover is closed, the device is ready to continue printing.

[0046] 6. Solar charging: In outdoor or powerless environments, the solar panel on the top of the device starts working and charges the device battery through the solar panel connection. The solar panel can automatically charge under light conditions, extend the battery life of the device, and ensure that the device has sufficient power during long-term use.

[0047] 7. Remote data upload and monitoring: During the entire invoicing process, the remote data transmission module continues to work and uploads the invoicing data to the cloud in real time. The backend management system can monitor the invoicing status of each device in real time to ensure the integrity and security of the data. Operators can also query and manage data through the backend system to facilitate error tracing and statistical analysis.

[0048] 8. Equipment charging: When charging is needed, the operator can connect the charger through the charging port at the bottom of the device. The charging port is directly connected to the device battery, ensuring a fast and efficient charging process. The device can still work normally during the charging process without affecting the invoicing operation.

[0049] 9. Equipment shutdown: After completing all invoicing work, the operator presses the power button to shut down the equipment. The equipment enters standby mode and all functional modules stop working to ensure the preservation of battery energy.
