[0023] The following will make an explanation of this patent in this embodiment according to the drawings and some embodiments.

[0024] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine the embodiments to elaborate on this patent in detail.

[0025] As Figures 1-3 shown, this patent relates to a children's educational toy, including a housing, a printing module, and a thermal control device.

[0026] In this embodiment, the housing includes a main housing, a top cover plate, and a fan blade device. The main housing adopts a closed hollow cavity structure, providing an internal space to accommodate the fan blade device, the thermal control device, and the transmission structure. The top cover plate is connected to the main housing through a hinge, facilitating the opening of the top cover for repair and replacement operations. The fan blade device is vertically arranged at the center position of the cavity of the main housing, including a rotating shaft and a plurality of arc-shaped fan blades. The surface of the fan blades is coated with a temperature-sensitive color-changing layer, which is attached to the blade surface through an ultrasonic welding process, making it present different colors when the temperature changes. The bottom end of the rotating shaft is connected to a driving motor through a coupling to achieve the rotation of the fan blades.

[0027] In this embodiment, the printing module includes an ink cartridge chamber installed upside down under the top cover plate, a flexible ink guide tube communicating with the ink cartridge chamber, and a nozzle assembly. The nozzle is vertically fixed directly above the fan blade, and the spraying direction is perpendicular to the surface of the fan blade, enabling the ink to be accurately printed on the surface of the fan blade. The ink cartridge chamber is installed on the inner wall of the top cover plate through a snap structure, facilitating the replacement of the ink cartridge. When the fan blade stops rotating, the nozzle can print preset patterns, characters, and numbers on the surface of the fan blade, thereby enhancing the interactive experience of children.

[0028] In this embodiment, the thermal control device includes a heating device and a heat dissipation device, and is regionally isolated by a heat insulation baffle. The heating device includes a heating chamber, a grid-shaped flow guide cover, a heating element, and a centrifugal air supply component. The heating chamber houses the heating element, and the centrifugal air supply component evenly guides the hot air to the surface of the fan blade, prompting the temperature-sensitive color-changing layer to change color; the heat dissipation device includes a heat dissipation chamber and an axial exhaust fan, which can quickly discharge the heat inside the housing, thereby reducing the temperature.

[0029] In this embodiment, the reward device includes a plurality of push buttons, a transmission mechanism, and a rotating gift box provided on the top surface of the top cover plate. The bottom of the push button is provided with an elastic reset spring, and a contact counter is installed below. When the button is operated a specific number of times, the counter will drive the transmission mechanism through a gear set. The output shaft of the transmission mechanism is connected to the rotating gift box, and the gift box rotates under the drive, aligning the item-taking port with different independent compartments, thereby providing reward items.

[0030] The children's educational toy of this patent provides an innovative structure that integrates visual stimulation and educational functions through the coordinated work of multiple components, utilizing the mutual cooperation of physical, mechanical, and thermosensitive characteristics. Its working principle is as follows:

[0031] Basic rotation principle:

[0032] The fan blade device realizes rotational motion by driving the rotating shaft through a motor, and realizes the intermittent rotation of the fan blade by controlling the start and stop of the motor.

[0033] Thermochromic mechanism:

[0034] The spectral reflection of the material molecules changes at different temperatures, thus presenting different colors. This color change process is reversible. As the temperature rises and falls, the color on the surface of the fan blade will also complete the switch within a short time, enhancing the visual effect and interactive fun of the toy.

[0035] When the thermochromic dye used in the thermosensitive material undergoes a temperature change, its molecular structure will undergo a reversible configurational change, thereby changing the light absorption and reflection characteristics, making the material present different colors. The specific principle is as follows: Low-temperature state: The dye molecules are in a stable state, and the absorption spectrum is concentrated in a specific wavelength range, and the material shows a preset color. High-temperature state: The increase in temperature causes changes in the bond angles or electron states within the molecule, changing the spectral absorption range, and the material presents another color. This process is fast and reversible, and the color change has an obvious visual impact, suitable for educational and interactive scenarios.

[0036] Window observation and safety guarantee:

[0037] The top cover plate window on the top of the housing corresponds to the rotation path of the fan blade. Children can directly observe the state of the fan blade through the window, and the transparent protective sheet embedded in the window effectively prevents children from being injured due to accidentally touching the high-speed rotating fan blade, ensuring the safety during use.

[0038] Hot air generation and action:

[0039] After the ceramic heating element in the heating cavity is powered on, it quickly heats up, and the hot air acts on the fan blade through the air supply component. This process enables the thermosensitive material to absorb heat and reach the color change threshold.

[0040] Heat dissipation:

[0041] The heat dissipation fan on the other side discharges the heat in the housing through the suction and exhaust action. The function of the heat dissipation fan helps to quickly reduce the temperature of the fan blade when needed, making it return to the original color and providing a new visual effect for subsequent operations.

[0042] Inkjet printing principle:

[0043] When the fan blade stops, the surface of its blade is precisely aligned with the spraying path to ensure the accurate position of the printed pattern or character.

[0044] Application of volatile ink:

[0045] Ink characteristics: The inkjet printing device uses volatile ink, and the ink naturally volatilizes without leaving permanent marks on the surface of the fan blade.

[0046] Reusable: Since no ink residue remains after evaporation, new text or patterns can be printed repeatedly on the fan blade surface.

[0047] 4. Literacy function:

[0048] Interactive learning: Letters, numbers, Chinese characters or simple patterns can be printed on the fan blades, and children can observe and perform recognition, spelling or matching tasks.

[0049] Dynamic changes: The color of the fan blades changes to present text with different color contrasts, adding dynamic interactive elements to the literacy process and enhancing the fun and attractiveness of learning.

[0050] 1. Conventionality of inkjet printing technology:

[0051] The inkjet printing device described in this embodiment belongs to the existing technology. Its core technologies include ink delivery, precise control of the injection head, and positioning of the injection path, which are common knowledge known to technicians in this field and have been widely used in traditional inkjet printing equipment. Therefore, its internal details will not be described in detail.

[0052] 2. Mature application of volatile ink:

[0053] As a widely used consumable material, volatile ink has been maturely applied in the fields of electronic paper and children's learning tools and belongs to the prior art. Its formula design (such as adding volatile solvents) and usage are well known to those skilled in the art.

[0054] Basic operation steps

[0055] 1. Start-up and temperature control color change effect display

[0056] Press the power switch of the toy to start the fan device and the heating device.

[0057] The motor starts to drive the rotating shaft, driving the fan blades to rotate. At the same time, the ceramic heating element in the heating device starts to heat up, and the air supply component blows hot air toward the rotating fan blades.

[0058] The fan blades are made of heat-sensitive material. As the temperature rises, the fan blades gradually change into different colors. Children can observe this dynamic effect through the transparent window on the top cover.

[0059] If cooling is required during the process, the cooling fan can be turned on. The cooling fan quickly discharges the hot air in the shell, lowers the surface temperature of the fan blades, and restores them to their original color, making it easier to perform temperature-controlled color change display.

[0060] 2. Inkjet pattern generation interaction

[0061] When the fan blades rotate intermittently, the fan blades are precisely aligned with the nozzles when they stop, and the inkjet printing device can be started. The nozzles absorb volatile ink from the ink tank through the ink conduit and directly act on the surface of the fan blades.

[0062] After use, the ink will gradually evaporate and the pattern on the fan blade surface will automatically disappear, making it easy to use again.

[0063] 3. Use of scoring and feedback functions

[0064] The points system adopts a three-level linkage mechanism:

[0065] Pressing the button triggers the contact counter (count value +1 each time you press it).

[0066] When the accumulated number reaches the set number (such as 5 times), the bevel gear set drives the second transmission shaft to rotate.

[0067] The energy storage flywheel drives the gift box ratchet to rotate 60°.

[0068] The gift box is driven to rotate so that the access port is aligned with different independent compartments, and the hatch of the corresponding compartment is aligned with the access port, so that the built-in reward items can be taken out.

[0069] Multi-function interactive mode description

[0070] 1. Linkage between temperature control mode and inkjet mode

[0071] The temperature-controlled color change can be combined with the inkjet pattern generation function to form a unique interactive mode. For example, the fan blade is first heated to a certain temperature by a heating device, and its color change effect is observed, and then the inkjet device is started to form an ink pattern on the fan blade after the color change.

[0072] 2. Application of intermittent rotation mode

[0073] If you want to create special pattern effects through rotation at different speeds and timings, you can switch to the intermittent motor drive mode. In this mode, the rotating shaft will drive the fan blades in a preset intermittent mode, and the fan blades will present a "stop-move-stop" rotation state.

[0074] By coordinating the ejection timing of the inkjet printing device, local patterns can be generated, further enhancing the fun and challenge of the game.

[0075] By integrating temperature-controlled color change, inkjet printing and scoring feedback functions, this children's educational toy can not only provide a rich visual and tactile experience, but also enhance children's creativity, observation and reaction ability through multi-mode interaction. The toy is cleverly designed, safe and reliable, suitable for children of different ages to carry out educational and entertainment activities, and can also be used as an interesting tool for parent-child interaction.
