Description

TECHNICAL FIELD

[0001] The utility model relates to a hollow ball's complete charging device, especially a complete charging device including a hollow ball and charging at the inflation and charging port of this hollow ball. BACKGROUND

[0002] In modern life, various hollow ball products are widely used in entertainment, decoration and other fields. Traditional hollow balls, such as light charging balls, often need separate charging interfaces, and the charging interface and the inflation port are usually separately arranged.

[0003] This brings a series of problems. On the one hand, the arrangement of multiple interfaces increases the manufacturing complexity and cost of hollow balls. In the production process, the charging interface and the inflation port need to be designed and processed separately, which not only consumes more materials and working hours, but also may affect the overall sealing and durability of the hollow ball due to too many interfaces.

[0004] On the other hand, for users, when using traditional hollow balls, they need to find the corresponding interface at different positions, which is relatively cumbersome. In an emergency, when charging or inflating a light charging ball, it may waste time because the correct interface cannot be found, reducing the convenience of use. Especially in some specific situations, such as outdoor activities, emergency lighting, etc., it is particularly important to quickly find and use the appropriate interface for charging or inflating.

[0005] In addition, multiple interfaces may also affect the appearance design of the hollow ball. In order to accommodate different interfaces, the surface of the hollow ball may need to be made more convex or concave, which destroys its overall smoothness and aesthetics.

[0006] After searching the prior art, it was found that the Chinese patent "A new wired charging basketball" with patent application number 201610275089.1. Since the outer surface of the cavity and the bladder form an airtight inflation chamber in this patent, the cavity and the bladder are completely integrated to ensure the air tightness of the ball. Therefore, it is actually impossible to complete inflation at the charging port, and another inflation port must be opened, so the problem of separate arrangement of the charging interface and the inflation port in the prior art has not been solved. The patent application number of WO2019061645A1 of the patent "Intelligent charging structure of inflatable ball" is found to be 201610275089.1. Although it can be arranged at the same port, the structure is very complex, but the technical solution to be implemented is very complex and the cost is high.

[0007] In summary, the existing hollow ball charging and inflation mode has problems of complicated manufacturing, inconvenient use and influence on appearance, and an all-set charging device capable of directly charging at the inflation port of the hollow ball is urgently needed to simplify the design and use of the hollow ball and improve its convenience and practicality. Utility model content

[0008] The utility model discloses a kind of all-set charging devices of hollow ball, can directly charge at the inflation port of the hollow ball, to simplify the design and use of the hollow ball, improve its convenience and practicality.

[0009] The utility model is realized through the following ways:

[0010] An all-set charging device of hollow ball, the hollow ball has a ball bladder containing gas, comprising a gas nozzle for charging and a charger; the gas nozzle comprises a rubber pad, a gas nozzle channel, a positive spring and a negative spring, the gas nozzle channel is fixed with the rubber pad, and the outlet of the gas nozzle channel is located inside the ball bladder; the positive spring and the negative spring are sequentially located inside the gas nozzle channel; the charger comprises a needle-shaped charging head, and the length of the needle-shaped charging head is at least two centimeters. The sequentially located inside the gas nozzle channel refers to the position close to the center of the hollow ball.

[0011] The length of a conventional needle-shaped charging head is generally not more than one centimeter, but in the present patent, a longer needle-shaped charging head is needed to adapt to its structure. The positive spring and the negative spring are in the gas nozzle channel inside the hollow ball, and these springs are the contact points for charging. To ensure that the needle-shaped charging head can stably contact the springs, it needs to have sufficient length. If the needle-shaped charging head is too short, it may not accurately contact the springs, especially when the internal space shape may change after the ball bladder is inflated, or in the case of slight shaking of the device, the contact may be interrupted. A length of at least two centimeters allows the charging head to have sufficient length to insert into the gas nozzle channel and still maintain good contact with the springs under a certain degree of displacement.

[0012] As a further improvement, the gas nozzle further comprises a housing and a charging chip, the housing is fixed with the rubber pad; the charging chip is fixed on the housing and connected with the positive spring and the negative spring; the inside of the housing is in communication with the inside of the ball bladder.

[0013] Unlike some structures in the prior art that have a "cavity and ball bladder integrated to ensure the air tightness of the ball", the structure of the housing communicating with the inside of the ball bladder allows the charging port to be inserted into the inflation needle for inflation, i.e., the charging port for insertion is also the inflation port.

[0014] As a further improvement, the rubber pad comprises a rubber sheet and a rubber head, the rubber head is located inside the rubber sheet. The rubber pad is composed of a rubber sheet and a rubber head, and the rubber head is located inside the rubber sheet. This design increases the sealing performance of the air nozzle. When the air needle or needle-shaped charging head is inserted or removed, the rubber head can better adapt to the shape change and fill the gap.

[0015] As a further improvement, the shell comprises an upper edge and a peripheral wall, the upper edge is fixed between the rubber head and the rubber sheet, and the rubber head is fastened between the peripheral wall. The upper edge of the shell is fixed between the rubber head and the rubber sheet, which makes the shell and the rubber pad tightly connected. On the one hand, it enhances the stability of the entire air nozzle structure, and even if the hollow ball is hit or shaken during use, the connection between the shell and the rubber pad is not easily loosened. On the other hand, the rubber head is fastened between the peripheral wall of the shell, further improving the sealing effect. The mutual cooperation between the shell and the rubber pad ensures the reliability of the air nozzle during long-term use, whether it is inflation or charging operation, it can run stably.

[0016] As a further improvement, the charging chip is fixed between the peripheral wall. This installation method makes the charging chip have a stable position in the shell. During the daily use and charging process of the hollow ball, the charging chip will not be displaced due to shaking or other external factors, ensuring the stable connection between the charging chip and the positive and negative spring sheets.

[0017] As a further improvement, the charging chip has a hole for the needle-shaped charging head to pass through, and the positive and negative spring sheets are located inside the hole. This design cleverly provides an accurate insertion path for the charging head. The positive and negative spring sheets are located inside the hole, and when the needle-shaped charging head is inserted, they can accurately contact the spring sheets to achieve the charging function. The said inside the hole means the position close to the center of the hollow ball.

[0018] As a further improvement, it also includes a fixing frame for fixing the positive and negative spring sheets, and the fixing frame is located inside the hole. The said inside the hole means the position close to the center of the hollow ball.

[0019] This further improves the stability of the spring sheet. During long-term use, the spring sheet will not be displaced or deformed due to repeated insertion and removal of the charging head, ensuring the reliability of the charging connection. Moreover, the fixing frame can keep the spring sheet in the right position and angle, ensuring good contact with the needle-shaped charging head, improving charging efficiency and safety.

[0020] As a further improvement, the shell is cylindrical, and the rubber head is conical, with the conical side located inside the hollow ball. The conical rubber head can better surround the inserted object after the insertion operation is completed, further enhancing the sealing effect.

[0021] As a further improvement, the diameter of the needle-shaped charging head is not more than the diameter of the air needle for inflating the hollow ball.

[0022] The air needle for inflating the hollow ball is designed to inject gas into the bladder. When designing the air nozzle structure, the size of the internal channel (including the rubber pad, air nozzle channel, etc.) is adapted to the size of the air needle to ensure smooth inflation. If the diameter of the needle-shaped charging head exceeds the diameter of the air needle, it is likely to expand the air nozzle channel when inserted into the air nozzle channel, causing the air nozzle to deform and damage.

[0023] As a further improvement, the needle-shaped charging head includes a center needle, a metal shell, and an insulating layer between the center needle and the metal shell. The center needle protrudes at the end of the charging head. The design of the center needle protruding at the end of the charging head is beneficial for the center needle to first contact the positive or negative spring leaf in the air nozzle. When inserting the air nozzle for charging, the center needle can accurately position and contact the spring leaf due to the protrusion, reducing the possibility of charging failure due to poor contact.

[0024] As a further improvement, the shell and charging chip are made of high-temperature resistant materials or protected by thermal insulation materials.

[0025] In the production of hollow balls, vulcanization is a critical step that plays a crucial role in improving the performance of the rubber skin. The vulcanization process of rubber generally requires a relatively high temperature, as the vulcanization reaction needs sufficient energy to activate the chemical reaction between rubber molecules and vulcanizing agents. Generally, the vulcanization temperature can reach 140-180 degrees Celsius, and in some special vulcanization processes, the temperature may be even higher. When the hollow ball skin is vulcanized, if the shell and charging chip do not have high-temperature protection measures, high temperature will cause serious damage to them. For the charging chip, the internal integrated circuit is composed of various semiconductor materials and metal wires. High temperature will change the performance of semiconductor materials, such as silicon-based semiconductors, whose electron mobility will change at high temperatures, causing the electrical performance of the chip to fail. At the same time, the metal wires in the chip may expand and oxidize due to high temperature, causing circuit breakage or short circuit. If the shell does not have high-temperature resistance or thermal insulation protection, it may deform at high temperatures, affecting its protection of the internal charging chip and other components. Moreover, shell deformation may cause loose connections with other components, damaging the structural integrity of the entire charging device. Since the high temperature of the vulcanization process is inevitable, installing the shell and charging chip in the unvulcanized skin is a key step to ensure that they are not damaged by high temperatures in subsequent vulcanization production. In general, thermal insulation materials need to withstand temperatures of two hundred degrees.

[0026] The utility model has the following advantages: 1, simplify the manufacture, integrate the charging and the inflation function in a air cock, reduce the interface quantity, reduce the manufacturing complexity, save production material and work hours. 2, improve the convenient use, and user need not seek the charging and the inflation interface in different positions, especially in the outdoor activity, emergency lighting etc. scene, can charge fast in the inflation port, easy operation, save time. 3, improve the appearance, avoid the convex or the depression of the hollow ball surface because of multiple interfaces, keep the smoothness and the aesthetic property of the whole hollow ball. 4, guarantee performance, guarantee the overall sealing property and the durability of the hollow ball. Meanwhile, the cover and the charging chip adopt high temperature resistant material or heat insulation protection, guarantee the normal progress of manufacturing process, and improve the use safety and reliability.

DETAILED DESCRIPTION

[0035] The utility model will be further explained in connection with specific drawings.

[0036] As Figure 7 shown, the hollow ball charging complete device includes the chargeable air cock 2 in the hollow ball and the matched charger 3. The ball bladder 1 containing gas is arranged in the hollow ball, and the air cock 2 as the key component integrates the charging and the inflation function.

[0037] As Figure 2 , Figure 3 , Figure 6 shown, the rubber pad 21 is composed of a rubber sheet 211 and a rubber head 212, and the rubber head 212 is located inside the rubber sheet 211. The rubber head 212 is designed as a conical shape, and the conical side faces the inside of the hollow ball. When the air needle or needle-shaped charging head is inserted or pulled out, the conical rubber head 212 can better adapt to the shape change, fill the gap, and enhance the sealing performance of the air nozzle 2.

[0038] The air nozzle channel 22 is fixed with the rubber pad 21, and its outlet is located inside the ball bladder 1. The positive spring 23 and the negative spring 24 are located inside the air nozzle channel 22 in turn, close to the position of the center of the hollow ball, which is the contact point for charging.

[0039] As Figure 2 , Figure 3 , Figure 4 shown, the cover 25 is cylindrical, including an upper edge 251 and a peripheral wall 252. The cover is not a complete cylinder, and the peripheral wall 252 does not completely isolate the cover 25 from the inside of the ball bladder. The channel 5 between the inside of the cover and the inside of the ball bladder is used to pass gas when inflating. The upper edge 251 is fixed between the rubber head 212 and the rubber sheet 211, and the rubber head 212 is fastened between the peripheral wall 252. This connection makes the cover 25 and the rubber pad 21 tightly combined, enhancing the stability and sealing performance of the structure of the air nozzle 2. Even if the hollow ball is hit or shaken by external force, the connection between the cover 25 and the rubber pad 21 is not easy to loosen.

[0040] The charging chip 26 is fixed between the peripheral wall 252 of the cover 25, and its position is stable and will not be displaced by external force during the daily use and charging process of the hollow ball. The charging chip 26 is provided with a hole 261 for the needle-shaped charging head to pass through, and the positive spring 23 and the negative spring 24 are located inside the hole 261, close to the center of the hollow ball. This provides an accurate insertion path for the charging head, ensuring that the charging head and the spring are in accurate contact to achieve the charging function.

[0041] It also includes a fixing frame 4 for fixing the positive spring 23 and the negative spring 24, and the fixing frame 4 is located inside the hole 261, close to the center of the hollow ball. This improves the stability of the spring, and in the case of long-term use and multiple insertion and removal of the charging head, the spring will not be displaced or deformed, ensuring the reliability of the charging connection, while ensuring that the spring is in the right position and angle, which is conducive to good contact with the charging head, improving the charging efficiency and safety.

[0042] The needle-shaped charging head of the charger 3 is at least two centimeters long, unlike the conventional needle-shaped charging head which is no more than one centimeter long. This design is to ensure that the charging head can still be in stable contact with the reed in the air nozzle 2 when the hollow ball bladder 1 changes in shape after being inflated or when the device is slightly shaken. The diameter of the needle-shaped charging head is no more than the diameter of the air needle used for inflating the hollow ball, so as to avoid expanding the air nozzle channel 22 when inserted into the air nozzle channel 22, preventing the air nozzle 2 from being deformed or damaged.

[0043] As shown in Figure 6 The needle-shaped charging head includes a central needle 31 and a metal shell 32, with an insulating layer 33 between the central needle 31 and the metal shell 32, and the central needle 31 protruding at the end of the charging head. This design allows the central needle 31 to first contact the positive reed 23 or negative reed 24 in the air nozzle 2, accurately positioning and contacting the reed when inserted into the air nozzle 2 for charging, reducing the failure rate caused by poor contact.

[0044] In the production of hollow balls, the rubber skin vulcanization process usually requires high temperature, generally 140-180 degrees Celsius. Vulcanization is crucial to improving the performance of the rubber skin, but high temperature can damage the cover 25 and the charging chip 26.

[0045] The cover 25 and the charging chip 26 are made of high-temperature resistant materials or protected by heat insulation materials that can withstand temperatures of up to 200 degrees Celsius. For example, ceramic materials such as alumina ceramic and silicon nitride ceramic can be used as the material for the cover 25, which has a high melting point, moderate or low thermal conductivity, and good chemical stability. For the charging chip 26, this high-temperature protection measure can prevent changes in the performance of semiconductor materials in its internal integrated circuits, such as changes in silicon-based semiconductor electron mobility and problems such as metal wire expansion and oxidation, to avoid circuit breakage or short circuits. At the same time, it can prevent the cover 25 from deforming and the connection from loosening, ensuring the structural integrity of the entire charging device.
