Those skilled in the art should understand that this application can be implemented without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0037] A printer is a device that converts digital information from a computer or other electronic device into a physical document. Its basic working principle is to control a print head or laser through signal processing, using ink or toner to form characters or images on the paper being transported. Based on different imaging principles and printing methods, printers are mainly classified into the following categories: dot matrix printers, inkjet printers, laser printers, 3D printers, etc. This application does not limit the type of printer.

[0038] Preferably, the printing mechanism in this application can be applied to an inkjet printer. An inkjet printer is a printing device that forms text or images by ejecting ink onto a printing medium, such as paper. The working principle of an inkjet printer is mainly based on microcontroller control. When the printing paper passes through the inkjet head, the main control circuit, driven by the printing signal, uses the corresponding inkjet printing technology, such as thermal inkjet technology, to eject ink onto the printing paper at an extremely high speed, thereby achieving inkjet printing.

[0039] Figure 1 is a structural block diagram of a printing mechanism according to an exemplary embodiment. As shown in Figure 1, it may include a printing module, a support plate 9, and a printing drive module.

[0040] The printing module includes a rotating frame 2, and a fixing part 3 is provided at one end of the rotating frame 2. The fixing part 3 is used to fix the ink cartridge 1 and improve the stability of ink jetting from the ink cartridge 1.

[0041] In one possible implementation, the fixing part 3 can be equipped with different fixing components depending on the fixing method. For example, the fixing part 3 can be a magnetic fixing part, with one or more magnetic materials provided on the rotating frame 2 and the material box 1. The magnetic attraction of the magnetic materials is used to attract the material box 1 to the rotating frame 2. The positions of the magnetic fixing blocks on the rotating frame and the magnetic fixing blocks on the material box 1 correspond. This application does not limit the number or type of magnetic materials. The fixing part 3 can also be a bolt-fastening fixing part, with threaded holes provided on the rotating frame 2, and the material box 1 fixed to the rotating frame 2 by bolts and nuts. The fixing part 3 can also be a slide rail fixing part, with slide rails provided on the rotating frame 2. After the material box 1 slides to a designated position via the slide rails, it is fixed by the locking device of the fixing part 3. The fixing part 3 can also be a snap-on fixing part, i.e., a slot, which can snap the material box 1 onto the rotating frame 2 by pressing or other means. This application does not limit the specific form of the fixing part 3.

[0042] Preferably, the material box 1 can be fixed by a magnetic fixing part. This setting can increase the internal space of the printing mechanism, making the structure simple and easy to operate.

[0043] A pivot is provided on the support plate 9, and a rotating hole is provided on the rotating frame 2. One end of the rotating frame 2 is rotatably connected to the pivot, that is, one end of the pivot is fixedly set on the support plate 9, and the other end is inserted into the rotating hole of the rotating frame 2, so that the two are rotatably connected.

[0044] In one possible implementation, a printing rotation gear 8 is provided at the bottom of one end of the rotating frame 2. The printing drive module includes a transmission assembly and a drive motor. The drive motor includes a drive shaft 5 and a motor unit 6. Both the transmission assembly and the drive shaft 5 are mounted above the support plate 9, and the motor unit 6 is mounted below the support plate 9. The motor unit 6 is rotatably connected to the drive shaft 5. One end of the transmission assembly meshes with the drive shaft 5 on the drive motor, and the other end meshes with the printing rotation gear 8. The motor unit 6 is located below the support plate 9. This mounting method saves space on the upper part of the support plate 9 and also prevents the heat generated by the motor unit 6 from affecting the rotation of the components above the support plate 9 while the printing mechanism is working.

[0045] In one possible implementation, the transmission assembly may include an input gear 4 and an output gear 7. An input pivot and an output pivot may be mounted on the support plate 9, wherein the input pivot is rotatably connected to the input gear 4, and the output pivot is rotatably connected to the output gear 7. After the input gear 4 and the output gear 7 are rotatably connected, one end of the input gear 4 meshes with the drive shaft 5 of the drive motor, and the other end of the input gear 4 meshes with one end of the output gear 7; the other end of the output gear 7 meshes with the printing rotary gear 8.

[0046] In another possible implementation, the transmission assembly may also include a transmission belt. This application does not limit the specific structure of the transmission assembly. The transmission belt can be directly fitted onto the printing rotary gear 8 and the drive shaft 5. Furthermore, one end of the transmission belt can be rotatably connected to the printing rotary gear 8, and the other end can be rotatably connected to the drive shaft 5. Further, when the motor unit 6 drives the drive shaft 5 to rotate, it can drive the printing rotary gear 8 to rotate, that is, through the transmission belt's rotatable connection to the printing rotary gear 8 and the drive shaft 5, thereby driving the rotating frame 2 to reciprocate around the pivot.

[0047] The working principle of the motor unit 6 is to receive signals from the main control board 14, convert electrical energy into mechanical energy, thereby driving the transmission components, and then driving the rotating frame 2 to swing back and forth around the pivot.

[0048] The types of drive motors in a printing mechanism can be as follows: Linear motors are motors that use electromagnetic fields to generate force for linear motion. When current passes through the motor's coil, a magnetic field is generated. This magnetic field interacts with the permanent magnets in the motor, thereby producing linear motion, causing the print head to slide across the printing medium and directly output text or images.

[0049] A stepper motor controls its rotation angle by receiving pulse signals. Each pulse signal selected by the stepper motor corresponds to a fixed angle. A stepper motor typically has multiple magnetic poles and coils; the direction of rotation is controlled by changing the direction of the current in the coils.

[0050] Servo motors achieve precise position and speed control through a closed-loop control system. Servo motors are typically equipped with feedback devices such as encoders or Hall effect sensors to monitor the motor's position and speed, and feed this information back to the main control board 14. The main control board 14 adjusts the motor's current and voltage based on the feedback information to maintain stable motor operation. This application does not limit the type of motor unit 6; it can be determined according to the actual situation.

[0051] Preferably, since the stepper motor receives digital control signals, i.e., electrical pulse signals, and converts them into corresponding angular or linear displacements, the stepper motor itself is an actuator capable of digital mode conversion. The stepper motor can also achieve open-loop position control, meaning it can precisely control rotational position and speed without feedback. Furthermore, by controlling the number and frequency of pulses and the phase sequence of the motor windings, the stepper motor can precisely control the rotation angle, speed, and direction of rotation. Position errors are very small (less than 1 / 10 degree) and do not accumulate. The brushless design of the stepper motor ensures a long service life. Therefore, the stepper motor has advantages such as high precision, smooth movement, controllable speed, and long service life. Furthermore, this application preferentially uses a stepper motor as the drive motor to drive the transmission components, thereby causing the rotating frame 2 to reciprocate around the pivot.

[0052] In one possible implementation, the printing mechanism further includes a main control board 14, which can be positioned above the printing module, the print drive module, and the paper transport module. The main control board 14 is the control module of the printing mechanism, responsible for acquiring and processing printing information provided by external devices.

[0053] External devices may include, but are not limited to, smartphones, desktop computers, tablets, laptops, smart speakers, digital assistants, augmented reality (AR) / virtual reality (VR) devices, smart wearable devices, and other similar electronic devices. Optionally, the operating system running on the electronic device may include, but is not limited to, Android, iOS, Linux, Windows, etc.

[0054] The main control board 14 is also equipped with a communication module, which may include a wired communication module for data transmission with external devices via a physical data cable. Wired communication may include Universal Serial Bus (USB), High Definition Multimedia Interface (HDMI), etc., all used to connect the printing mechanism and external devices, allowing external devices to transmit printing information to the main control board 14 via wired transmission methods such as USB. This application does not limit the wired communication method of the printing mechanism. The communication module may also include a wireless communication module, such as Wi-Fi (IEEE 802.11), Bluetooth, Zigbee (IEEE 802.15.4), NFC (Near Field Communication), etc., which are not limited in this application.

[0055] Printing information may include data such as printed documents and images, as well as user-defined printing parameters, such as the number of copies and print quality; this application does not limit this. After the main control board 14 obtains printing information from an external device, this printing information is usually not directly applicable to the printing format. Therefore, the main control board 14 needs to parse and process this information, converting it into instructions that can be understood and executed by the various components inside the printer. That is, after parsing the printing information, the main control board 14 generates corresponding printing instructions. Furthermore, the main control board 14 sends the printing instructions to various modules in the printing mechanism, such as the printing module, the printing driver module, and the paper transport module.

[0056] After the print drive module receives the print command sent by the main control board 14, the motor unit 6 will drive the input gear 4 to rotate. At the same time as the input gear 4 rotates, the output gear 7 also rotates synchronously, thereby driving the print rotating gear 8 to oscillate back and forth, that is, driving the rotating frame 2 to oscillate back and forth around the pivot.

[0057] In one possible implementation, the printing mechanism further includes at least one carriage origin sensor 10, wherein the carriage origin sensor 10 is a sensor capable of detecting and determining the origin position or reference position of the carriage movement.

[0058] In the printing mechanism of this application, the carriage origin sensor 10 can be set on the support plate 9, that is, set on both sides of the pivot. Specifically, it can be set at the leftmost origin position where the printing module can rotate. This way, when the main control board 14 drives the printing module to rotate around the pivot for printing, even if the printing module swings to the leftmost origin position, it can accurately swing back around the pivot, thereby ensuring print quality and normal operation of the printing mechanism.

[0059] The type of printhead origin sensor 10 includes a photoelectric sensor, which determines the rotational position of the print module by the obstruction or reflection of a light beam. The photoelectric sensor consists of a transmitter and a receiver. The transmitter emits a light beam; when the printer's cartridge 1 rotates to the origin position, i.e., the starting position, the light beam is obstructed or reflected by the print module, and the receiver detects this change and generates a trigger signal.

[0060] A magnetic sensor determines the rotational position of the printing module by detecting a magnetic mark. The magnetic sensor works by installing a magnetic mark on the printing module or along its rotational path; when the sensor detects this mark, it immediately generates a trigger signal. A mechanical switch detects the printing module's position through physical contact. Specifically, a mechanical switch is installed at the origin position of the printing module. When the printing module rotates to the origin position, it triggers the mechanical switch, which then generates a trigger signal. This application does not limit the type of the carriage origin sensor 10; it can be determined according to the actual situation.

[0061] The carriage origin sensor 10 monitors the rotational position of the printing module in real time. When it detects that the printing module has swung to the origin position, it automatically generates a trigger signal and transmits it to the main control board 14. After receiving the trigger signal from the carriage origin sensor 10, the main control board 14 immediately controls the drive motor to reverse, that is, controls the printing module to swing in the opposite direction around the pivot. This setting can improve the efficient and stable operation of the printing mechanism.

[0062] In one possible implementation, a corresponding carriage origin sensor 10 can be set at the rightmost origin position of the printing module's rotation in the printing mechanism. The two carriage origin sensors 10 can operate simultaneously, monitoring the origin positions on either side of the printing module's rotation, i.e., the starting and ending positions of the material box 1's movement. Thus, when the printing module rotates to the starting position, the carriage origin sensor 10 at the starting position can generate a trigger command corresponding to the starting position. Upon receiving the trigger command from the starting position, the main control board 14 immediately controls the drive motor, causing the printing module to rotate in reverse around the pivot. Similarly, the carriage origin sensor 10 at the ending position can generate a trigger command corresponding to the ending position and send it to the main control board 14. Upon receiving the trigger command from the ending position, the main control board 14 immediately controls the drive motor to rotate forward, allowing the printing module to rotate forward around the pivot.

[0063] Figure 3 is a schematic diagram illustrating the rotation angle of a printing module according to an exemplary embodiment. As shown in Figure 3, the printing module can swing left and right around a pivot, thereby achieving rotary inkjet printing. Exemplarily, the angle of rotation of the printing module around the pivot can be set to 135°. This application does not limit the rotation angle of the printing module, and it can be determined according to the actual situation.

[0064] In another possible implementation, two carriage origin sensors 10 are set. One is set at the starting position of the printing module's rotation, and the other is set at the ending position of the printing module's rotation, i.e., the origin positions on both sides of the printing module. The carriage origin sensor 10 at the starting position is used to monitor the starting position of the printing module's rotation, while the carriage origin sensor 10 at the ending position can serve as a backup carriage origin sensor 10. If the carriage origin sensor 10 at the starting position fails, the main control board 14 will immediately send a printing command to the carriage origin sensor 10 at the ending position. The carriage origin sensor 10 at the ending position will immediately monitor the printing module, thereby ensuring that the printing module can stably print in the printing area.

[0065] After receiving the trigger signal from the print head origin sensor 10 at the starting position, the main control board 14 immediately determines the preset end position based on the trigger signal, and then calculates the distance and direction that the printing module needs to swing. Further, based on the required swing distance and direction of the printing module, it controls the drive motor to rotate forward and reverse along the starting and end positions. Forward rotation can mean the printing module swings around a pivot from the starting position to the end position, and reverse rotation can mean the printing module swings around a pivot from the end position to the starting position. This application does not limit the starting and end positions.

[0066] Figure 4 is a structural diagram of a paper conveying module according to an exemplary embodiment. As shown in Figure 4, the printing mechanism further includes a paper conveying module and a paper drive motor 13. A paper conveying slot is provided on the support plate 9, which is located in front of the printing module and is used to fix the paper conveying module. The paper conveying module includes a paper drive assembly 16 and a paper drive rod 15. One end of the paper drive assembly 16 is rotatably connected to the paper drive rod 15 through a bearing or other rotating connector on the paper connecting rod 15, and the other end of the paper drive assembly 16 is rotatably connected to the paper drive motor 13 through a coupling or other rotating connector on the paper drive motor 13.

[0067] The paper transmission assembly 16 can be a combination of multiple paper transmission gears, that is, multiple paper transmission gears transmit power through meshing. The paper transmission motor 13 drives one of the multiple paper transmission gears to rotate, and through the meshing between the gears, it drives the paper transmission rod 15 to rotate.

[0068] The paper transmission assembly 16 can also be a combination of a paper transmission gear and a paper transmission belt. The paper transmission motor 13 drives the driving gear in the paper transmission gear to rotate, and the paper transmission gear drives the driven gear in the paper transmission gear to rotate through the paper transmission belt, thereby driving the paper transmission rod 15 to rotate. This application does not limit the type of paper transmission assembly 16, and it can be determined according to the actual situation.

[0069] The printing mechanism also includes a paper tip sensor 17 and a paper storage module. The paper storage module, located below the support plate 9, can be designed as a paper tray or paper compartment for storing and supplying printing paper. An openable cover is located below the paper storage module; the cover can be made of robust metal or plastic to ensure durability and stability. Users can manually open and close the cover to place paper into the paper storage module. This application does not limit the capacity of the paper storage module; the specific number of sheets of paper it can hold can be determined based on actual needs.

[0070] In one possible implementation, a paper inlet can be provided on the outer side of the printing mechanism, and a corresponding switch module is also provided on the outside of the printing mechanism. When there is paper inside the printing mechanism, the paper inlet is in a closed state, which can effectively prevent dust from entering the interior of the printing mechanism and keep the printed paper clean. When there is no paper inside the printing mechanism, the user can open the paper inlet through the switch module. Then, the paper is pushed from the paper inlet to the paper storage module. Correspondingly, the paper is placed in the paper storage module, i.e., the accurate paper output position, by the paper limiting unit. After the user has placed the paper, the paper inlet is further closed by the switch module. This application does not limit the structure for placing the paper.

[0071] A paper tip sensor 17 is positioned at the paper output port of the paper transport module, in front of the paper drive rod, to detect the tip position of the paper, ensuring that the paper enters the printing area correctly and aligned for printing. The printing task begins after an external device sends printing information to the main control board 14. Upon receiving the printing information, the main control board 14 instructs the paper transport module to perform transport processing according to preset printing settings. Under the action of the paper transport module, the paper begins to move from the paper storage module to the printing area. Correspondingly, the main control board 14 also instructs the paper tip sensor 17, located at the paper output port of the paper transport module, to begin monitoring the paper output port. Upon detecting that paper has appeared at the output port, the paper tip sensor 17 immediately sends the paper's transport position to the main control board 14. After receiving the paper's transport position, the main control board 14 immediately sends a printing command to the printing module and the printing drive module, enabling the printing mechanism to perform rotational printing on the paper to be printed.

[0072] The paper tip sensor 17 can be a transmissive paper tip sensor. A transmissive paper tip sensor uses components such as photodiodes and photosensitive diodes to project light onto the paper surface, utilizing the transmission and reflection of light to monitor the tip position and size of the paper. The working principle of a transmissive paper tip sensor is: light shines from a light-transmitting component onto the paper surface, passes through the paper, and then strikes another photoelectric element; the tip position of the paper is determined by detecting the amount of transmitted light. The paper tip sensor 17 can also be a reflective paper tip sensor. A reflective paper sensor projects light onto the paper surface and uses the reflection of light to detect the tip position of the paper. The working principle of a reflective paper sensor is that light shines onto the paper surface and is reflected back; the intensity and duration of the reflected light are detected by a photosensitive element to determine the tip position of the paper. This application does not limit the type of paper tip sensor 17.

[0073] In one possible implementation, the printing mechanism further includes a printhead scraper 12 and an ink-absorbing cotton 11. The support plate 9 may have a scraper groove for fixing the printhead scraper 12, ensuring its stability and reducing installation and maintenance difficulty. This application does not limit the shape and size of the printhead scraper 12. Specifically, the printhead scraper 12 is located outside the carriage origin sensor 10. The ink-absorbing cotton 11 has an ink-absorbing groove, which connects it to the printhead scraper 12. Multiple printheads are located at the bottom of the ink cartridge 1, each with multiple small nozzles. If the printing mechanism is not used or turned on for a long time, dried ink may accumulate in the nozzles of the ink cartridge 1, easily causing blockages and affecting print quality. Therefore, when the printing mechanism is put into use, the main control board 14 first controls the drive motor to swing the ink cartridge 1 to the position of the printhead scraper 12. Furthermore, the printhead scraper 12 can scrape the ink from the nozzles at the bottom of the ink cartridge 1 to remove any clogging ink, thereby improving printing efficiency and accuracy in subsequent printing processes. After the printhead scraper 12 completes the scraping, the ink flows directly along the scraper 12 to the absorbent cotton 11. This design ensures smooth ink discharge and prevents ink accumulation and contamination inside the printing mechanism. Through the absorption function of the absorbent cotton 11, the entire printing mechanism remains clean and dry, thus extending its service life and improving print quality.

[0074] The ink cartridge 1 is a component in the printing mechanism used to store and supply the ink or toner required for printing. The ink cartridge 1 can refer to an ink cartridge, i.e., a component in an inkjet printer used to store printing ink. The ink cartridge 1 can also refer to a toner cartridge, i.e., used to store solid toner. This application does not limit the specific type of ink cartridge 1. Preferably, this application uses an ink cartridge as the material for the ink cartridge 1 of the printing mechanism. Ink cartridges can be divided into black ink cartridges or color ink cartridges according to color. Black ink cartridges are mainly used for printing black text and images. Color ink cartridges can contain different colors of ink, such as cyan, magenta, yellow, etc., used for printing color graphics and photos, meeting richer printing needs. This application does not limit the type of ink cartridge; the specific type can be determined according to the actual situation. This application does not limit the arrangement or number of printheads on the ink cartridge.

[0075] After receiving printing information from an external device, the main control board 14 converts the printing information into a dot matrix format, determining which positions require ink ejection and which do not. The main control board 14 sends printing commands to the drive motor, which then rotates forward and backward, causing the printing module to swing around a pivot. Simultaneously, the main control board 14 also sends printing commands to the paper drive motor 13, which adjusts the paper position so that the paper moves forward at a constant speed each time the printing module rotates from the starting position to the ending position.

[0076] The ink cartridge 1 of the printing mechanism can employ thermal inkjet technology. Inside the printhead of ink cartridge 1, each nozzle is connected to a miniature heating resistor. When current passes through this resistor, it rapidly heats to a very high temperature, typically 300°C. At this point, the heating resistor causes the ink in contact to evaporate instantaneously, forming a bubble. This bubble rapidly expands, pushing the surrounding ink towards the nozzle. As the bubble expands, it ejects a small droplet of ink, typically a few picoliters in volume, from the nozzle and onto the printed paper. The bubble then cools and bursts, creating a negative pressure within the nozzle, attracting new ink to fill the nozzle, ready for the next ejection.

[0077] The ink cartridge 1 of the printing mechanism can also employ piezoelectric inkjet technology. The ink cartridge 1 is equipped with a printhead drive unit, which is connected to the main control board 14. The main control board 14 sends electrical signals to the printhead drive unit based on dot matrix data. These electrical signals can precisely control the timing of ink droplet ejection from each nozzle on the printhead in the ink cartridge 1. The printhead drive unit is equipped with one or more piezoelectric crystals, which are connected to the nozzles, and can be configured so that each nozzle corresponds to one piezoelectric crystal. After the main control board 14 sends an electrical signal to the piezoelectric crystal, the piezoelectric crystal deforms, thereby squeezing the ink in the ink chamber out of the nozzle and ejecting it at extremely high speeds, such as thousands of drops per second, onto a flat surface to form text or patterns. This application does not limit the printing technology used for sampling in the ink cartridge 1; the specific technology can be determined according to the actual situation.

[0078] In one possible implementation, the printing mechanism further includes a battery module and a port substrate. The battery module provides a stable power supply to components such as the main control board 14 and the printing drive module. The battery module is also connected to the port substrate, which has a charging interface. This charging interface typically uses a recognized charging protocol, such as USB or Type-C, to ensure compatibility with various charging devices. When the printing mechanism's power is low, the user can insert a charging cable into the charging interface to connect the battery module to a charging device for charging. This application can also install a wireless charging receiver inside the printing mechanism, which is connected to the charging module. When the printing mechanism's power is low, the user can place a dedicated wireless charging adapter at a designated location on the printing mechanism to begin the wireless charging process. This application does not limit the method of charging the battery module.

[0079] This application employs a rotary oscillating inkjet printing mechanism, enabling the printing module to achieve large-scale printing within a smaller space. This significantly reduces the overall size of the printing device, making the printing mechanism more compact and allowing for the integration of more functional modules within a limited space. Consequently, integrating this printing mechanism into a portable inkjet printer enhances the user experience, allowing users to directly print images or text outdoors or in other scenarios.
