Description

Technical Field

[0001] The invention relates to a complete set of charging equipment for a hollow ball, in particular to a complete set of equipment comprising a hollow ball and a charging port for charging the hollow ball. Background Art

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

[0003] This brings a series of problems. On the one hand, the setting of multiple interfaces increases the manufacturing complexity and cost of the hollow ball. During the production process, the charging interface and the inflation port need to be designed and processed separately, which not only consumes more materials and man-hours, but may also 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 corresponding interfaces in different locations, which is cumbersome to operate. When it is urgent to charge or inflate the luminous charging ball, time may be wasted because of not being able to find the correct interface, which reduces the convenience of use. Especially in some specific occasions, 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 have more protrusions or depressions, which destroys its overall smoothness and aesthetics.

[0006] A search of the prior art revealed a Chinese patent for "A New Wired Rechargeable Basketball" with a patent application number of 201610275089.1. Since the outer surface of the cavity in the patent forms an airtight inflation chamber with the bladder, the cavity and the bladder are completely integrated to ensure the airtightness of the ball. Therefore, it is actually impossible to complete the inflation at the charging port, and a separate inflation port must be opened. Therefore, the problem of separate settings of the charging interface and the inflation port in the prior art is not solved. It was found that the patent WO2019061645A1 with a patent application number of 201610275089.1 in "An Intelligent Charging Structure for Inflatable Balls" can realize the setting of the inflation port and the charging interface at the same port, but its structure is very complicated, but the technical solution to be implemented is very complicated and costly.

[0007] In summary, the existing hollow ball charging and inflation methods have problems such as complex manufacturing, inconvenient use, and affected appearance. There is an urgent need for a charging set that can charge directly at the inflation port of the hollow ball to simplify the design and use of the hollow ball and improve its convenience and practicality. Summary of the invention

[0008] The purpose of the present invention is to design a charging set for a hollow ball, which can directly charge the hollow ball at the inflation port, so as to simplify the design and use of the hollow ball and improve its convenience and practicality.

[0009] The present invention is achieved in the following ways: A complete set of charging devices for a hollow ball, wherein the hollow ball has a bladder containing gas, and includes a gas nozzle and a charger that can be used for charging; the gas nozzle includes a rubber pad, a gas nozzle channel, a positive reed, and a negative reed, the gas nozzle channel is fixed to the rubber pad, and the outlet of the gas nozzle channel is located inside the bladder; the positive reed and the negative reed are sequentially located inside the gas nozzle channel; the charger includes 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 a position close to the center of the hollow ball.

[0010] The length of a conventional needle-shaped charging head is generally no more than one centimeter, but in this patent, in order to adapt to its structure, a longer needle-shaped charging head is required. There are positive and negative reeds in the air nozzle channel inside the hollow ball, and these reeds are the contact points for charging. In order to ensure that the needle-shaped charging head can stably contact the reeds, it needs to be of sufficient length. If the needle-shaped charging head is too short, it may not be able to accurately contact the reeds, especially when the shape of the internal space may change after the bladder is inflated, or when the device shakes slightly, the contact may be interrupted. A length of at least two centimeters allows the charging head to have sufficient length to be inserted into the air nozzle channel, and to maintain good contact with the reeds under a certain degree of displacement.

[0011] As a further improvement, the air nozzle also includes a cover shell and a charging chip, and the cover shell is fixed to the rubber pad; the charging chip is fixed on the cover shell and connected to the positive electrode reed and the negative electrode reed; the interior of the cover shell is connected to the interior of the ball bladder.

[0012] Different from some structures in the prior art in which "the cavity and the bladder are completely integrated to ensure the airtightness of the ball", a structure in which the interior of the cover is connected to the interior of the bladder allows the charging port to be inserted with an inflation needle for inflation, that is, the charging port for insertion is also the inflation port.

[0013] As a further improvement, the rubber pad includes a rubber sheet and a rubber head, and the rubber head is located on the inner side of the rubber sheet. The rubber pad is composed of a rubber sheet and a rubber head, and the rubber head is located on the inner side of 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 pulled out, the rubber head can better adapt to its shape change and fill the gap.

[0014] As a further improvement, the cover shell includes an upper edge and a peripheral wall, the upper edge is fixed between the rubber head and the film, and the rubber head is fastened between the peripheral walls. The upper edge of the cover shell is fixed between the rubber head and the film, and this connection method makes the cover shell and the rubber pad tightly combined. On the one hand, the stability of the entire air nozzle structure is enhanced. During the use of the hollow ball, even if it is hit or shaken by external force, the connection between the cover shell and the rubber pad is not easy to loosen. On the other hand, the rubber head is fastened between the peripheral walls of the cover shell, which further improves the sealing effect. This mutually coordinated structural design between the cover shell and the rubber pad ensures the reliability of the air nozzle during long-term use, and it can operate stably whether it is inflating or charging operations.

[0015] As a further improvement, the charging chip is fixed between the peripheral walls. This installation method allows the charging chip to have a stable position in the housing. During the daily use and charging of the hollow ball, the charging chip will not shift due to shaking or other external factors, ensuring a stable connection between the charging chip and the positive and negative reeds.

[0016] As a further improvement, the charging chip has a hole for the needle-shaped charging head to pass through, and the positive and negative reeds are located on the inner side of the hole. This design cleverly provides an accurate insertion path for the charging head. The positive and negative reeds are located on the inner side of the hole, and when the needle-shaped charging head is inserted, they can accurately contact the reeds to achieve the charging function. The positions located on the inner side of the hole in sequence refer to the positions close to the center of the hollow ball.

[0017] As a further improvement, it also includes a fixing frame for fixing the positive electrode spring and the negative electrode spring, and the fixing frame is located inside the hole. The inside of the hole refers to a position close to the center of the hollow ball.

[0018] The stability of the reed is further improved. During long-term use, the reed will not be displaced or deformed due to repeated plugging and unplugging of the charging head, ensuring the reliability of the charging connection. In addition, the fixing frame can keep the reed in the appropriate position and angle to ensure good contact with the needle-shaped charging head, improving charging efficiency and safety.

[0019] As a further improvement, the cover shell is cylindrical, the rubber head is conical, and one side of the cone is located inside the hollow ball. After the insertion operation is completed, the conical rubber head can better surround the inserted object and further enhance the sealing effect.

[0020] As a further improvement, the diameter of the needle-shaped charging head does not exceed the diameter of the air needle used to inflate the hollow ball.

[0021] The air needle used to inflate the hollow ball is designed to inject gas into the bladder. When designing the air nozzle structure, the size of its 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, when inserted into the air nozzle channel, it is likely to expand the air nozzle channel, causing deformation and damage to the air nozzle.

[0022] As a further improvement, the needle-shaped charging head includes a center needle and a metal shell, an insulating layer is provided between the center needle and the metal shell, and the center needle protrudes at the end of the charging head. The center needle protrudes at the end of the charging head, and this design facilitates the center needle to contact the positive reed or the negative reed in the gas nozzle first. When the gas nozzle is inserted for charging, the protruding center needle can accurately locate and contact the reed, reducing the possibility of charging failure due to poor contact.

[0023] As a further improvement, the cover shell and charging chip are made of high temperature resistant materials or protected by heat insulating materials.

[0024] In the production of hollow balls, vulcanization is a key step and plays a vital role in improving the performance of the rubber outer skin. The vulcanization process of rubber usually needs to be carried out at a higher temperature because the vulcanization reaction requires sufficient energy to activate the chemical reaction between the rubber molecules and the vulcanizing agent. Generally speaking, the vulcanization temperature can reach 140-180 degrees Celsius, and even in some special vulcanization processes, the temperature may be higher. When the outer skin of the hollow ball is vulcanized, if the cover and the charging chip are not protected by high temperature, the high temperature will cause serious damage to them. For the charging chip, the integrated circuit inside it is composed of various semiconductor materials and metal wires. High temperature can change the performance of semiconductor materials. For example, the electron mobility of silicon-based semiconductors 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 temperatures, which may lead to circuit breakage or short circuit. If the cover is not resistant to high temperatures or heat insulation protection, it may deform at high temperatures, affecting its protective effect on the internal charging chip and other components. Moreover, the deformation of the cover may cause the connection with other components to loosen, destroying the structural integrity of the entire charging device. Since high temperatures during the vulcanization process are unavoidable, the order of installing the cover and charging chip in the unvulcanized outer skin is the key to ensure that they are protected from high temperature damage during subsequent vulcanization production. Generally speaking, thermal insulation materials need to withstand temperatures of 200 degrees.

[0025] The present invention has the following advantages: 1. Simplified manufacturing, integrating the charging and inflation functions into one air nozzle, reducing the number of interfaces, reducing manufacturing complexity, and saving production materials and working hours. 2. Improved ease of use. Users do not need to find charging and inflation interfaces in different locations. Especially in outdoor activities, emergency lighting and other scenarios, they can quickly charge at the inflation port, which is simple to operate and saves time. 3. Improved appearance, avoiding bulges or depressions on the surface of the hollow sphere due to multiple interfaces, and maintaining the overall smoothness and aesthetics of the hollow sphere. 4. Guaranteed performance, ensuring the overall sealing and durability of the hollow sphere. At the same time, the cover and the charging chip are made of high temperature resistant materials or heat insulation protection, which ensures the normal progress of the manufacturing process and improves the safety and reliability of use.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with the specific drawings.

[0028] like Figure 7 As shown, the hollow ball charging device comprises a rechargeable gas nozzle 2 in the hollow ball and a matching charger 3. A bladder 1 for containing gas is provided in the hollow ball, and the gas nozzle 2 is a key component, integrating charging and inflation functions.

[0029] like Figure 2 , Figure 3 , Figure 6As 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 to be conical, with its conical side facing 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.

[0030] The air nozzle channel 22 is fixed to the rubber pad 21, and its outlet is located inside the ball bladder 1. The positive electrode spring 23 and the negative electrode spring 24 are located in sequence inside the air nozzle channel 22, close to the center of the hollow ball, and they are contact points for charging.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, the cover 25 is cylindrical and includes an upper edge 251 and a peripheral wall 252. The cover is not a complete cylindrical shape, and the peripheral wall 252 does not completely isolate the cover 25 from the inside of the bladder. The channel 5 between the inside of the cover and the inside of the bladder is used to pass the 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 method makes the cover 25 and the rubber pad 21 tightly combined, and enhances the stability and sealing of the air nozzle 2 structure. 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.

[0032] The charging chip 26 is fixed between the peripheral walls 252 of the cover 25, and its position is stable, and it will not be displaced by external forces 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 electrode reed 23 and the negative electrode reed 24 are located inside the hole 261, close to the center of the hollow ball, providing an accurate insertion path for the charging head, ensuring that the charging head and the reed are in accurate contact to achieve the charging function.

[0033] It also includes a fixing frame 4 for fixing the positive electrode reed 23 and the negative electrode reed 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 reed, and the reed will not be displaced or deformed in the case of long-term use and multiple plugging and unplugging of the charging head, ensuring the reliability of the charging connection, while ensuring that the reed is in a suitable position and angle, which is conducive to good contact with the charging head, and improving charging efficiency and safety.

[0034] The needle-shaped charging head of the charger 3 is at least two centimeters long, which is different from the conventional needle-shaped charging head that does not exceed one centimeter. This design is to ensure that the charging head can still stably contact the reed in the air nozzle 2 when the shape of the internal space of the hollow ball bladder 1 changes after inflation or the device shakes slightly. The diameter of the needle-shaped charging head does not exceed the diameter of the air needle used to inflate the hollow ball, so as to avoid stretching the air nozzle channel 22 when inserted into the air nozzle channel 22, and prevent the air nozzle 2 from being deformed or damaged.

[0035] like Figure 6 As shown, the needle-shaped charging head includes a center needle 31 and a metal shell 32. An insulating layer 33 is provided between the center needle 31 and the metal shell 32, and the center needle 31 protrudes at the end of the charging head. This design allows the center needle 31 to first contact the positive reed 23 or the negative reed 24 in the gas nozzle 2, and can accurately locate and contact the reed when inserted into the gas nozzle 2 for charging, thereby reducing the possibility of charging failure caused by poor contact.

[0036] In the production of hollow balls, the vulcanization process of the rubber outer skin usually requires a relatively high temperature, generally 140-180 degrees Celsius. Vulcanization is essential for improving the performance of the rubber outer skin, but high temperatures can damage the cover 25 and the charging chip 26.

[0037] The cover 25 and the charging chip 26 are made of high temperature resistant materials or protected by heat insulating materials, and the heat insulating materials need to be able to withstand a high temperature of 200 degrees. For example, ceramic materials, such as alumina ceramics and silicon nitride ceramics, can be used as the cover 25 material, 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 the performance of the semiconductor materials in its internal integrated circuit from changing, such as changes in the electron mobility of silicon-based semiconductors and expansion and oxidation of metal wires, thereby avoiding line disconnection or short circuit. At the same time, it can prevent the cover 25 from deformation and loose connections, thereby ensuring the structural integrity of the entire charging device.
