The present disclosure belongs to the technical field of sports goods, and particularly relates to a sports ball.
There are a variety of ball games, including basketball, volleyball, football and table tennis, which are played during the day and night.
With the improvement of people's living standards, the existing sports balls can no longer meet the needs of consumers due to their monotonous appearance color.
In order to overcome the above shortcoming of the prior art, the present disclosure provides a sports ball, which is ultraviolet (UV)-photochromic and luminous to enhance its appearance color expression.
The present disclosure is achieved by the following technical solution. The present disclosure provides a sports ball. The sports ball includes an inflatable ball or a non-inflatable ball, where a photosensitive layer is provided on an outer side of the non-inflatable ball;
the inflatable ball includes an inner bladder; an outer side of the inner bladder is bonded to a patch layer through an adhesive layer; a valve core is fixed and penetrates from an inner side of the inner bladder to an outer side of the patch layer, such that the inner side of the inner bladder communicates with the outer side of the patch layer through the valve core; a spacer groove is formed between the outer side of the inner bladder and the patch layer; a sealing strip is bonded to an inner side of the spacer groove; and the photosensitive layer is provided on the outer side of the patch layer;
the photosensitive layer is made by uniformly mixing UV photochromic powder, a phosphor, transparent essential oil, and toluene;
the adhesive layer is made by uniformly mixing resin glue and an anti-aging agent; and
an outer side of the photosensitive layer is provided with a wear-resistant coating.
Compared with the prior art, the present disclosure has the following advantages:
The photosensitive layer is provided on the outer side of the patch layer of the inflatable ball or the outer side of the non-inflatable ball. The UV photochromic powder presents different colors in response to light, and the phosphor glows in case of dim light. This design facilitates the position determination of the ball, and enhances the appearance color expression so as to improve the ball's attraction to the consumers.
Other features, objectives, and advantages of the present disclosure will become more apparent by reading the detailed description of non-limiting embodiments with reference to the following accompanying drawings.
Reference Numerals: 1. inner bladder; 2. patch layer; 3. adhesive layer; 4. valve core; 5. spacer groove; 6. sealing strip; and 7. photosensitive layer.
Referring to
The adhesive layer 3 is made by uniformly mixing resin glue and an anti-aging agent. The resin glue is used to improve the peel resistance after bonding, and the anti-aging agent is used to prolong the aging life thereof.
A valve core 4 is fixed and penetrates from an inner side of the inner bladder 1 to an outer side of the patch layer 2, such that the inner side of the inner bladder 1 communicates with the outer side of the patch layer 2 through the valve core 4. A spacer groove 5 is formed between the outer side of the inner bladder 1 and the patch layer 2. A sealing strip 6 is bonded to an inner side of the spacer groove 5. A photosensitive layer 7 is provided on the outer side of the patch layer 2. An outer side of the photosensitive layer 7 is provided with a wear-resistant coating to protect the photosensitive layer 7.
The photosensitive layer 7 is made by uniformly mixing UV photochromic powder, a phosphor, transparent essential oil, and toluene.
An outer end of the valve core 4 is not exposed to the outer side of the patch layer 2.
An outer side of the sealing strip 6 is provided with anti-skid bumps to increase friction and facilitate use.
The outer side of the photosensitive layer 7 is provided with a wear-resistant coating.
The inflatable ball may be a basketball, a volleyball, or a football, etc.
Referring to
The photosensitive layer 7 is made by uniformly mixing UV photochromic powder, a phosphor, transparent essential oil, and toluene.
The outer side of the photosensitive layer 7 is provided with a wear-resistant coating.
The non-inflatable ball may be a table tennis ball or a bowling ball, etc.
In the present disclosure, the UV photochromic powder absorbs UV light of a specific wavelength, and changes its color by the energy of the light. When the UV light of the specific wavelength disappears, the UV photochromic powder restores its original color.
The basic principles, main features and advantages of the present disclosure are described above. For those skilled in the art, it is obvious that the present disclosure is not limited to the details of the above embodiments, and the present disclosure can be implemented in other specific forms without departing from the spirit or basic features of the present disclosure. The embodiments should be regarded as exemplary and non-limiting in every respect, and the scope of the present disclosure is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of equivalent elements of the claims should be included in the present disclosure. The reference numeral in the claims should not be considered as limiting the involved claims.
It should be understood that although this specification is described in accordance with the embodiments, not every embodiment includes only an independent technical solution. Such a description is merely for the sake of clarity, and those skilled in the art should take the specification as a whole. The technical solutions in the embodiments can also be appropriately combined to form other implementations which are comprehensible for those skilled in the art.
