[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A balancing hemisphere includes a base 1, a honeycomb skeleton structure 2 that is snapped onto the top of the base 1, an inner plate structure 3 that is snapped onto the top of the honeycomb skeleton structure 2, an inflatable hemisphere 4 that is snapped onto the top of the inner plate structure 3, an annular ring 5 that is wrapped around the outer edge of the inflatable hemisphere 4, a cleaning component 6 that is mounted on the top pivot of the annular ring 5, bolt fasteners 7 that are provided at the bottom of the base 1, and handles 8 that are provided on both sides of the honeycomb skeleton structure 2.

[0025] Furthermore, an inflatable hemisphere 4 is snapped onto the top of the internal plate-like structure 3. The inflatable hemisphere 4 serves as the main contact surface for users' balance training. An annular ring 5 is wrapped around its outer edge, protecting the edge of the hemisphere 4 and providing a mounting base for the cleaning component 6. The cleaning component 6 is mounted on the top pivot of the annular ring 5. The cleaning component 6 includes a connecting shaft 601, an arc-shaped seat 602, a pull rod 603, a tension spring 604, and a filling sponge brush 605. The connecting shaft 601 is located on the outer wall of the annular ring 5, connecting it to the arc-shaped seat 602, allowing the arc-shaped seat 602 to rotate flexibly around the connecting shaft 601. A tension spring 604 is installed inside the arc-shaped seat 602, and the pull rod 603 is movably connected to the tension spring 604. 604 provides adjustable pressure for the filling sponge brush 605, ensuring that it can closely adhere to the surface of the inflatable hemisphere 4 for cleaning. The filling sponge brush 605 is internally engaged with the arc-shaped base 602. The outer wall of the filling sponge brush 605 has a limiting groove, and the pull rod 603 is engaged and fixed with the limiting groove. At the same time, the inner wall of the arc-shaped base 602 is provided with a magnetic adsorption layer, and magnetic material is embedded in the edge of the filling sponge brush 605. The double fixing method ensures the stability of the filling sponge brush 605 during the cleaning process and prevents it from falling off.

[0026] Furthermore, connecting rods are provided on both sides of the annular ring 5, and the connecting shaft 601 is sleeved on the connecting rods, which further enhances the stability of the cleaning component 6 during installation. The annular ring 5 is also provided with a liquid injection hole, which is connected to the liquid guiding channel inside the filling sponge brush 605. Users can inject cleaning liquid through the liquid injection hole to make the filling sponge brush 605 perform better during cleaning.

[0027] Furthermore, the bottom of the base 1 is provided with bolt fasteners 7. The edge of the inflatable hemisphere 4 is connected to the base 1 through the bolt fasteners 7. The bolt fasteners 7 are bolt assemblies with adjustable tightness. By rotating the adjusting nut, the tightness of the connection between the inflatable hemisphere 4 and the base 1 can be finely adjusted to ensure that the overall structure can maintain good stability in different usage scenarios.

[0028] Furthermore, the honeycomb-shaped frame structure 2 has handles 8 on both sides. The surface of the handles 8 is decorated with anti-slip textures, which are wavy or serrated, effectively increasing friction and making it easier for users to grip during balance training, thus improving comfort and safety. The bottom of the base 1 has an anti-slip pad with a replaceable modular design. The pad connects to the base 1 via magnetic attraction or slots, allowing users to replace it with pads of different anti-slip properties depending on the usage scenario, such as smooth or rough surfaces, further enhancing the stability of the balance hemisphere.

[0029] The outer wall of the inflatable hemisphere 4 is coated with a fluoropolymer nanomaterial coating. Utilizing its superhydrophobic and superoleophobic properties, it makes it difficult for stains to adhere to the surface of the inflatable hemisphere 4, reducing stain accumulation, lowering the difficulty of cleaning, and further improving the product's cleaning convenience and hygiene.

[0030] Working Principle: In use, first, align the honeycomb frame structure 2 with the locking part on the top of the base 1, and gently press to ensure a secure connection. Ensure the honeycomb frame structure 2 is accurately positioned on the base 1 and will not shift. Place the inner plate structure 3 on top of the honeycomb frame structure 2, connecting it using the same locking method. Ensure the vent holes on the inner plate structure 3 correspond to the interior of the subsequently installed inflatable hemisphere 4 to ensure unobstructed air pressure balance. Lock the inflatable hemisphere 4 onto the top of the inner plate structure 3, ensuring a tight fit. Then, use the bolt fasteners 7 and adjust the nut to connect the edge of the inflatable hemisphere 4 to the base 1. Adjust the tightness according to actual usage requirements to ensure overall structural stability and reliability. Inflate the hemisphere. An annular ring 5 is wrapped around the outer edge of the hemisphere 4, so that the annular ring 5 fits tightly against the edge of the inflatable hemisphere 4, providing a stable installation base for the cleaning component 6. The connecting shaft 601 is installed on the connecting rod on the outer wall of the annular ring 5. Then, the arc-shaped seat 602 is connected to the annular ring 5 through the connecting shaft 601, ensuring that the arc-shaped seat 602 can rotate flexibly around the connecting shaft 601. Next, a tension spring 604 is installed inside the arc-shaped seat 602, and the pull rod 603 is movably connected to the tension spring 604. Finally, the filling sponge brush 605 is snapped into the arc-shaped seat 602, so that the pull rod 603 is engaged and fixed with the limiting groove on the outer wall of the filling sponge brush 605. At the same time, the magnetic adsorption layer on the inner wall of the arc-shaped seat 602 and the magnetic material on the edge of the filling sponge brush 605 attract each other, doubly fixing the filling sponge brush 605.

[0031] Secondly, handles 8 are installed on both sides of the honeycomb skeleton structure 2 to ensure that the handles 8 are firmly installed and that the anti-slip texture on the surface is reasonably oriented to facilitate user grip. Depending on the usage scenario, a suitable anti-slip pad is selected and installed on the bottom of the base 1 by magnetic attraction or slot to complete the overall assembly of the balance hemisphere.

[0032] Finally, when stains appear on the surface of the inflatable hemisphere 4 and need cleaning, first inject an appropriate amount of cleaning fluid through the injection hole on the annular ring 5, allowing the cleaning fluid to enter the filling sponge brush 605 through the liquid guide channel. Hold the pull rod 603 and push the arc-shaped seat 602 to rotate around the connecting shaft 601, so that the filling sponge brush 605 fits tightly against the surface of the inflatable hemisphere 4 and wipes and cleans along the surface of the inflatable hemisphere 4 to remove stains. If the filling sponge brush 605 has been used for a long time or is damaged, it can be removed from the arc-shaped seat 602 by separating the pull rod 603 from the limiting groove and using the interaction force between the magnetic adsorption layer on the inner wall of the arc-shaped seat 602 and the magnetic material of the filling sponge brush 605. Replace or clean it. After cleaning and drying, reinstall it back into the arc-shaped seat 602 according to the installation steps.
