Background technology:

Pre-school education is the initial stage of educational activities and the first stage of education in life. As the saying goes, the plan for a day lies in the morning, and the plan for a year lies in the spring. As the initial education of life, preschool education mainly includes sports, intellectual education, moral education and aesthetic education. Among them, intellectual education points to the process of human cognitive development, cultivating cognitive interests and habits, and developing intelligence for the purpose. The contents of intellectual education mainly include sensory education, the cultivation of language communication ability, the promotion of children's understanding of the environment, and the cultivation of children's ability to solve problems; aesthetic education, which points to the development process of people's aesthetic ability, with the cultivation and development of people's aesthetic ability as the main goal. The content of moral education mainly includes natural beauty, social beauty, artistic beauty, formal beauty and so on. Writing training is indispensable to intellectual education, and there is no shortage of languages. And aesthetic education is not without drawing training. For the object of preschool education for children, these contents need to have a certain degree of interest, in order to attract children's attention and improve the effect of education.

There are two types of equipment that provide these trainings: paper and electronic equipment; however, the paper after the paper has been trained is often not reused, and the cumulative cost is extremely high. For picture training, paper cannot directly and clearly modify the painted colors, and the training effect is poor. For electronic equipment, the cost of a single piece is extremely high, and the touch of writing cannot be really substituted in writing training, so the training effect is not good. In the drawing training, the details of the drawn picture cannot be controlled, and it is also difficult to simulate the shade change of the color in the reality, thus the training effect is not good. Coupled with the diversity of content that can be carried by electronic devices, it is possible to encroach on young children's time, thereby reducing the initiative to complete the learning goals set for them.

Technical realization elements:

The purpose of the present invention is to solve the above problems and provide a multi-layer interspersed core-changing educational and puzzle writing suit.

The technical scheme of the present invention is: a multi-layer interspersed core-changing educational puzzle writing suit, which is characterized in that it comprises a card-inserting writing board, a variety of plastic puzzle cards with the same size, and a magnetic identification block;

The card insertion writing board includes a frame assembly, a whiteboard and a bracket installed in the frame assembly, and is characterized in that: the frame assembly includes a square upper frame and a square lower frame with matching sizes, the outer edge of the inner surface of the upper frame is provided with a circle of outer convex edge armour, the outer surface of the upper frame is provided with a door-shaped boss, and a card insertion slot is provided between the bottom surface of the boss and the outer surface of the upper frame, the outer edge of the inner surface of the lower frame is provided with an outer convex edge B with the same size as the outer convex edge A, the middle of the inner surface of the upper frame is provided with a circle of inner convex edge A, a clamping groove A is formed between the inner side of the inner convex edge A and the inner edge of the upper frame, and the middle of the inner surface of the lower frame is provided with an inner convex edge B with the same size as the inner convex edge A, A clamping groove B is formed between the inner side of the inner convex edge B and the inner edge of the lower frame, the size of the outer convex edge A is the same as the size of the inner convex edge B, and the size of the clamping groove A is the same as the size of the clamping groove B The same, one end of the outer surface of the upper frame and the position corresponding to the entrance of the card slot are provided with multiple friction protrusions;

A plurality of connecting bosses are evenly distributed in the groove formed between the outer convex edge A and the inner convex edge A. A plurality of connecting cylinders matching the size of the connecting bosses are evenly distributed in the groove formed between the outer convex edge B and the inner convex edge B. The connecting cylinders are inserted into the grooves on the connecting bosses to fixedly connect the upper frame and the lower frame, the above-mentioned whiteboard is clamped between the clamping groove A and the clamping groove B, the whiteboard includes cardboard and two thin iron sheets, the size of the thin iron sheet is the same as the size of the cardboard, the two thin iron sheets are symmetrically pasted on the front and back of the cardboard, the surface of the thin iron sheet is coated with white paint;

The puzzle card is inserted into the card slot of the card writing board and covers the whiteboard in the middle of the card writing board. The lower surface of the outer end of the puzzle card is pressed on the above-mentioned friction protrusion, and the identification block with magnetic force is magnetically attracted to the whiteboard.

Preferably, the puzzle card is a scene game card, and the scene on the upper surface of the scene game card is a farm, a zoo, or a family.

Preferably, the identification block with magnetic force is the same as the animal or character on the scene game card, and the identification block with magnetic force is magnetically attracted to the scene game card and covers the character or animal on the surface thereof.

Preferably, the puzzle card is a life common sense cognitive card, and the upper surface of the life common sense cognitive card is provided with an ambulance, a police car, a thermometer or a clock without a pointer.

Preferably, the puzzle card is a game card, and the game on the game card is a Gobang game, Sudoku game and a coloring game.

Preferably, the puzzle card is a learning card, which includes a math interest learning card, a Chinese phonetic learning card, an English writing practice learning card or a curriculum planning card.

The beneficial effects of the present invention are: the multi-layer interspersed core-changing educational puzzle writing suit of the present invention includes a card insertion writing board, a magnetic identification block, and a puzzle insertion card. The card writing can be directly written or painted. Wipe and modify; the puzzle card can be inserted into the card insertion slot of the card insertion tablet, and then learn, play, paint, learn common sense of life, etc. on the puzzle card; the identification block with magnetic force is used in conjunction with the card, and the identification block with magnetic force can be adsorbed on the animal or character of the puzzle card for identification, thus improving the learning and discrimination ability of children.

The invention can not only bring intuitive feelings to writing training and drawing training, improve the training effect, but also can be reused, the overall cost is low, and the increased interest of the identification block with magnetic force can improve the attention of young children, thereby improving the initiative to complete the learning goals set for them.
