Description

Technical Field

[0001] The invention relates to the technical field of air pumps, and in particular to a portable air pump. Background Art

[0002] An air pump is an inflatable device used to provide air pressure to various inflatable objects such as tires, air cushions, inflatable toys, swimming rings, etc. When driving on the road, if the tire pressure is insufficient, the air pump can quickly replenish the air pressure to ensure driving safety. For people who ride bicycles or motorcycles, it is good to carry an air pump with you, which can be used when the tire is leaking or the air pressure needs to be adjusted. When camping or camping, the air pump can be used to inflate inflatable mattresses, inflatable pillows, etc. to improve comfort. At the seaside or by the swimming pool, the air pump can quickly inflate swimming rings, inflatable boats, etc., saving time and effort. For example, sports equipment that needs to be inflated, such as basketballs and footballs, can also be quickly inflated using an air pump.

[0003] The core components of the air pump are the motor and compressor, which directly determine the power and efficiency of the air pump. To increase the inflation speed, a larger motor and compressor are usually required, which increases the size of the device. Conversely, if the size of the motor and compressor is reduced, although the volume and weight can be reduced, the inflation speed will be slower. Higher inflation speed means greater power output, which generates more heat. To prevent overheating, the air pump needs to be equipped with a heat dissipation structure, such as a heat sink or fan, which also takes up additional space. Reducing the size often means a reduction in heat dissipation capacity, which may cause the air pump to fail to work efficiently for a long time. Some efficient air pumps may be equipped with a small air tank and a pressure regulator inside to ensure stable air pressure output. These components also take up space and affect the overall size of the air pump. Although removing these components can reduce the volume, it will affect the inflation performance and user experience.

[0004] Therefore, there is a balance between the volume of the air pump and the inflation speed. To increase the inflation speed while maintaining portability, it is usually necessary to optimize the design and materials. For example, using a more efficient motor, improving the compressor design, enhancing the heat dissipation structure, etc. However, these improvements often also increase costs. The portable air pumps currently on the market usually find a compromise between portability and performance to meet the needs of most users.

[0005] For example, the Chinese authorized patent "A portable multifunctional air pump for tire-specific gas" with application number CN202010482503.2 includes: a shell part, an air pump part, a control part and a battery; it is characterized in that: the air pump part consists of a sealed air pump chamber, a sealing cover, a sealing ring, an air pump, a motor, an air extraction component and an air filling component; the sealed air pump chamber is located in the base, and the motor and the air pump connected by the shaft are placed in it as a whole, and the sealing cover is sealed by the sealing ring to form a closed space; the air extraction component includes an air extraction pipe and an air extraction connecting pipe interface, one end of the air extraction component is connected to the air extraction pipe interface on the sealed air pump chamber, and the air filling component includes an air filling pipe and an air filling connecting pipe interface, and one end of the air filling component is connected to the air filling pipe interface on the air pump. The present invention mainly seals the air pump in a closed space, leaving only a dedicated air extraction pipe interface, so as to achieve the function of filling the automobile tire with tire-specific gas.

[0006] Although the above-mentioned existing technology has certain progress, it has a complex structure and a large size, and is only suitable for inflating car tires. When faced with more small-scale inflation uses, the large and complex mechanical mechanism makes it inconvenient to carry and has low stability.

[0007] In view of the above situation, in order to overcome the above technical problems, the present invention designs a portable air pump to solve the above technical problems. Summary of the invention

[0008] The technical purpose to be achieved by the present invention is to design a portable air pump that is adapted for inflating small scenes, such as sports balls, swimming rings, etc. The air pump can also be used to clean some places that are not suitable for cleaning.

[0009] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0010] A portable air pump comprises a driving component, a movable component, an exchange component, a sealing component, a fixing bolt and an air outlet pipe. The movable component, the exchange component and the sealing component are sequentially mounted on the side of the driving component, and the components are fixed by fixing bolts to ensure the stability and reliability of the entire structure. The air outlet pipe is mounted on the side of the sealing component and is used to deliver compressed air to an object that needs to be inflated. In the working process of the air pump, the driving component plays a key role. It is mainly responsible for driving the silicone block in the movable component to open and close at an inclined angle. This movement causes the volume of the compressed cavity inside the silicone block to change. As the inclination angle of the silicone block changes continuously, the volume of the compressed cavity also increases or decreases accordingly. In the process of volume change, according to the principle that gas pressure is inversely proportional to volume, the air pressure inside the silicone block also changes accordingly. When the volume of the compressed cavity of the silicone block increases, the internal pressure decreases, forming a negative pressure environment. At this time, the outside air is sucked into the compressed cavity of the silicone block under the action of atmospheric pressure, completing the air absorption process. Then, driven by the drive assembly, the silicone block continues to change its tilt angle, gradually reducing the volume of the compressed cavity and increasing the internal air pressure. As the internal pressure increases, the air is compressed and pressurized, and finally guided to the outlet pipe through the exchange assembly and released to the outside. This process ensures that air can be continuously inhaled and pressurized, thereby achieving inflation of external equipment. The fixing bolt plays a vital role in this device. It stabilizes each component to ensure that the parts will not shift or loosen during the inflation process, thereby improving the durability and safety of the air pump. The presence of the sealing component effectively prevents air leakage during transmission and improves the efficiency and performance of the entire air pump. This design not only makes the air pump compact and easy to carry, but also simplifies the internal mechanical structure through the flexible use of silicone blocks, reduces production costs and maintenance difficulties. At the same time, the tilting movement of the silicone block is used to change the cavity volume, which reduces the friction loss of traditional piston air pumps and extends the service life of the equipment. The operation process of the entire system is smooth and efficient, and is suitable for a variety of inflation needs, such as bicycle tires, car tires, inflatable toys and outdoor equipment.

[0011] The design structure of the drive assembly is relatively compact and delicate, including a protective shell, a mounting cavity, a drive motor, a rotating shaft and an eccentric block. The protective shell is designed to be cylindrical, which plays a role in protecting the internal core components and preventing the external environment from damaging the internal structure. The interior of the protective shell is provided with a mounting cavity for accommodating and fixing the drive motor. The drive motor is the core part of the entire drive assembly, which directly provides power to enable the air pump to operate.

[0012] The installation cavity is precisely positioned so that the drive motor can be firmly installed in it to avoid loosening or displacement during operation. The output end of the drive motor is connected to the rotating shaft, which is an important medium for power transmission. Once the drive motor is started, the rotating shaft will rotate and transmit the power generated by the motor. An eccentric block is installed on the rotating shaft. This design can convert the rotational motion of the rotating shaft into an irregular motion form, providing the necessary conditions for the subsequent inflation process.

[0013] The eccentric block is installed in the middle of the rotating shaft. The purpose of this eccentric design is to generate specific mechanical movement. Through the rotation of the eccentric block, other components can be driven to tilt or swing, thereby changing the volume of the compressed cavity inside the silicone block. This series of precise designs enables the entire drive component to efficiently convert electrical energy into mechanical energy during operation, providing a continuous source of power for the operation of the air pump.

[0014] Designing the rotating shaft into a symmetrical V-shape and setting the eccentric block at its symmetrical center has the following advantages: Better balance: The symmetrical V-shaped structure keeps the rotating shaft in a good balance during rotation, reducing vibration and instability during operation. This balance can reduce noise and wear during mechanical operation and improve the service life and stability of the equipment. Reduce eccentric force: The eccentric block is set at the symmetrical center, which can effectively reduce the impact of eccentric force on the rotating shaft and drive motor. Under normal circumstances, the eccentric block will generate centrifugal force, causing lateral force on the rotating shaft, which will cause vibration and bearing wear. Through the symmetrical V-shaped design, the eccentric forces offset each other on both sides, which can reduce the burden on the bearings and motors. Improve transmission efficiency: This design can more effectively convert the rotary motion of the motor into the reciprocating motion of the moving components, improving transmission efficiency. The V-shaped structure is conducive to transmitting the rotary power of the drive motor more directly to the eccentric block, reducing energy loss and making the air pump more efficient when working. Reduce wear and maintenance costs: Due to the balance and design of reducing eccentric force, the friction and wear between the rotating shaft and other components are reduced. This means that after a long period of operation, the equipment will have less wear on the bearings and other mechanical parts, extending the equipment's maintenance cycle and reducing maintenance costs. Compact structure: The symmetrical V-shaped design makes the entire drive assembly more compact while maintaining efficient operation. This helps to reduce the overall size of the air pump, enhance portability, and make it more suitable for outdoor or emergency use. Reduce the impact of vibration on other components: By accurately setting the position of the eccentric block, the impact of vibration on other components can be minimized, thereby avoiding problems such as loose bolts and seal failure caused by vibration, and improving the reliability of the entire machine.

[0015] The movable assembly is composed of a movable disk, a silicone block, a cross and a matching block, and the overall design is compact and the matching is precise. The movable disk is installed on the side of the driving assembly as the basic supporting structure of the entire movable assembly. The silicone block is tightly attached to the side of the movable disk. Driven by the movable disk, the silicone block can open and close at an inclined angle, thereby changing the volume of the internal compression cavity to achieve the purpose of inhaling and compressing air.

[0016] A cross is mounted above the silicone block. The cross helps stabilize the silicone block so that it maintains a precise trajectory during operation. A mating block is fixed at the center of the cross. The mating block enables good coordination between the drive assembly and the active assembly. The mating block converts the rotational motion of the drive assembly into the reciprocating motion of the silicone block through interaction with the eccentric block, ensuring the efficient operation of the air pump. This series of designs enables the active assembly to play a key role in the inflation process, ensuring the performance and efficiency of the air pump.

[0017] The number of the silicone blocks is 3 to 6, and a circular array is installed on the side of the movable plate. The cross can control the expansion and contraction of the silicone block, so that the volume of the cavity inside the silicone block changes.

[0018] The silicone block has an ingenious structural design and includes three main parts: a compression cavity, a positioning column and a clamping ring. The compression cavity is located inside the silicone block and is the key area for the air pump to compress air. Driven by the movable component, the volume of the compression cavity changes continuously to achieve the suction and compression of air. A positioning column is provided at the bottom of the silicone block. The function of the positioning column is to provide a fixed support point for the silicone block to ensure its stability during operation and prevent deviation or shaking.

[0019] A snap ring is installed on the positioning column, which plays a role of stabilization and locking. The radius of the snap ring is precisely set to 1.2 times the radius of the positioning column. This design provides appropriate tightening force to ensure that the silicone block will not fall off or loosen due to vibration or pressure changes during operation. At the same time, the size ratio between the snap ring and the positioning column also ensures the flexibility of the silicone block, enabling it to smoothly change the tilt angle, thereby effectively changing the volume of the compression cavity and achieving efficient air compression and release process.

[0020] The structure of the exchange assembly consists of a fixed disk, an exchange port, a fixed ring, a first control pad and a second control pad, and the overall design is intended to achieve effective control of air flow. The fixed disk is installed on the side of the active assembly as the basic support part of the exchange assembly, providing a stable support for the entire system. The exchange port is located on the surface of the fixed disk and is a channel for air circulation. Through it, air can smoothly enter and leave the compression cavity, thereby realizing the functions of inflation and deflation.

[0021] The side of the fixed plate is equipped with a fixing ring to ensure the tight connection between the components to prevent loosening or leakage during operation. This fixing ring also enhances the overall stability of the exchange assembly, ensuring that the components can maintain normal operation under high pressure and high speed operation. The No. 1 control pad is installed on the side of the fixed plate to regulate and guide the air flow. It ensures that the air can flow along the predetermined path and improve the efficiency of the air pump. The No. 2 control pad is located inside the exchange port and is specifically responsible for finely controlling the inlet and outlet of the air flow. By adjusting the position and angle of the No. 2 control pad, the size and flow rate of the air pressure can be effectively controlled to ensure that the air remains stable and controllable during the compression process of the silicone block. This design enables the air pump to maintain good performance in different environments and conditions, ensuring an efficient and safe inflation process.

[0022] The control pad No. 1 and the control pad No. 2 are both made of soft materials. This material selection helps to enhance the sealing performance of the components and ensure that there will be no air leakage during the process of compressing and releasing the air. The control pad No. 2 is designed to be circular. This special shape can more flexibly adjust the flow of air, allowing the air to pass through the exchange port more smoothly. To ensure a precise fit, the outer diameter of the control pad No. 1 is exactly equal to the inner diameter of the fixed ring. This design allows the control pad No. 1 to be firmly installed inside the fixed ring to avoid displacement during operation. At the same time, the diameter of the control pad No. 2 is the same as the diameter of the exchange port, ensuring that the control pad No. 2 can fit tightly against the exchange port, thereby effectively controlling the in and out of air.

[0023] The fixing ring includes three parts: a ring body, a support block and a mounting pin. The ring body is the main part of the fixing ring, which is responsible for providing fixing and support. It is located in the middle of the exchange port to ensure that the connection with the exchange port is stable and accurate. The support block is installed on the outer side of the ring body, mainly used to enhance the contact surface between the fixing ring and the fixed disk, and improve the overall stability. The setting of the support block helps to disperse the pressure and reduce the risk of deformation or damage under high-pressure operation. The mounting pin is fixed on the ring body. Through precise positioning of the mounting pin, a close connection between the fixing ring and other components is ensured to prevent loosening or falling off during use, thereby ensuring the stability and reliability of the entire air pump system.

[0024] The sealing assembly includes three main parts: a sealing ring, a dustproof frame and an air outlet, which are designed to ensure the sealing and air circulation of the air pump. The sealing ring is installed on the side of the exchange assembly, which plays a sealing role to prevent air leakage during compression and discharge. The dustproof frame is installed inside the sealing ring. The purpose of the dustproof frame is to protect the internal components from the invasion of external dust and impurities, thereby ensuring the long-term stable operation of the air pump. The side of the dustproof frame is equipped with a dustproof net, which effectively blocks the entry of tiny particles and keeps the internal environment clean. The air outlet is set in the middle of the sealing ring and communicates with the air outlet pipe to ensure that the compressed air can flow out smoothly and be delivered to the equipment that needs to be inflated. The overall design effectively improves the working efficiency and reliability of the air pump.

[0025] The beneficial effects of the present invention are as follows:

[0026] 1. The present invention realizes an efficient inflation process through a carefully designed movable component, which specifically includes the cooperation of an eccentrically rotating rotating shaft, a cross, a silicone block and a control pad. The eccentrically rotating rotating shaft drives the cross, so that the compression cavity inside the silicone block is continuously compressed and expanded. Due to the design of the eccentric block, the rotation of the rotating shaft can be effectively converted into the reciprocating motion of the silicone block, thereby realizing efficient air compression. This design enables the silicone block to accurately adjust its volume in different working stages, thereby improving the inflation efficiency. Accurate air pressurization: The setting of control pad No. 1 and control pad No. 2 realizes precise control of air flow. Control pad No. 1 adjusts the path of air flowing into the silicone block, while control pad No. 2 is responsible for adjusting the path of air outflow. This design ensures that the air can maintain a stable pressurized output after compression, thereby meeting the requirements of different inflation needs.

[0027] 2. The overall structural design of the present invention is compact, and it fully utilizes the advantages of miniaturization, so that the air pump is small in size while maintaining high efficiency, and is easy to carry and store. The compact design also makes the device suitable for use in limited spaces, such as vehicle storage or outdoor carrying. Due to the eccentric rotation design and excellent structural coordination, the air pump generates less noise during operation. The rotation mode of the eccentric block effectively reduces vibration and noise, and improves the user experience, especially when used in places that require a quiet environment, such as homes or offices, it can significantly reduce noise interference. These design advantages work together, so that the air pump of the present invention reaches a high level in terms of performance, portability and user experience, while meeting various inflation needs, and improving the convenience and comfort of use.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] like Figure 1-9 As shown, a portable air pump includes a driving component 1, a movable component 2, an exchange component 3, a sealing component 4, a fixing bolt 5 and an air outlet pipe 6. The movable component 2, the exchange component 3 and the sealing component 4 are sequentially mounted on the side of the driving component 1, and the components are fixed by the fixing bolt 5 to ensure the stability and reliability of the entire structure. The air outlet pipe 6 is mounted on the side of the sealing component 4 to deliver compressed air to the object to be inflated. In the working process of the air pump, the driving component 1 plays a key role. It is mainly responsible for driving the silicone block 22 in the movable component 2 to open and close at an inclined angle. This movement causes the volume of the compression cavity 221 inside the silicone block 22 to change. As the inclination angle of the silicone block 22 changes continuously, the volume of the compression cavity 221 also increases or decreases accordingly. In the process of volume change, according to the principle that gas pressure is inversely proportional to volume, the air pressure inside the silicone block 22 also changes accordingly. When the volume of the compression cavity 221 of the silicone block 22 increases, the internal pressure decreases, forming a negative pressure environment. At this time, the outside air is sucked into the compression cavity 221 of the silicone block 22 under the action of atmospheric pressure, completing the air absorption process. Then, driven by the drive component 1, the silicone block 22 continues to change the tilt angle, so that the volume of the compression cavity 221 gradually decreases and the internal air pressure increases. As the internal pressure increases, the air is compressed and pressurized, and finally guided to the outlet pipe 6 through the exchange component 3 and released to the outside. This process ensures that the air can be continuously inhaled and pressurized, thereby achieving the inflation of the external equipment. The fixing bolt 5 plays a vital role in this device. It stabilizes each component to ensure that each part will not shift or loosen during the inflation process, thereby improving the durability and safety of the air pump. The presence of the sealing component 4 effectively prevents the leakage of air during the transmission process, and improves the efficiency and performance of the entire air pump. This design not only makes the air pump compact and easy to carry, but also simplifies the internal mechanical structure through the flexible use of the silicone block 22, reducing the production cost and maintenance difficulty. At the same time, the volume of the cavity is changed by the tilting movement of the silicone block 22, which reduces the friction loss of the traditional piston air pump and prolongs the service life of the equipment. The operation process of the whole system is stable and efficient, and is suitable for a variety of inflation needs, such as bicycle tires, car tires, inflatable toys and outdoor equipment.

[0042] like Figure 3-4As shown, the design structure of the drive assembly 1 is relatively compact and delicate, including a protective shell 11, a mounting cavity 12, a drive motor 13, a rotating shaft 14 and an eccentric block 15. The protective shell 11 is designed to be cylindrical, which plays a role in protecting the internal core components and preventing the external environment from damaging the internal structure. The interior of the protective shell 11 is provided with a mounting cavity 12 for accommodating and fixing the drive motor 13. The drive motor 13 is the core part of the entire drive assembly 1, which directly provides power to enable the air pump to operate.

[0043] The installation cavity 12 is precisely opened so that the drive motor 13 can be firmly installed therein to avoid loosening or displacement during operation. The output end of the drive motor 13 is connected to the rotating shaft 14, which is an important medium for power transmission. Once the drive motor 13 is started, the rotating shaft 14 will rotate accordingly to transmit the power generated by the motor. An eccentric block 15 is installed on the rotating shaft 14. This design can convert the rotational motion of the rotating shaft 14 into an irregular motion form, providing the necessary conditions for the subsequent inflation process.

[0044] The eccentric block 15 is installed in the middle of the rotating shaft 14. The purpose of this eccentric design is to generate a specific mechanical movement. Through the rotation of the eccentric block 15, other components can be driven to tilt or swing, thereby changing the volume of the compression cavity 221 inside the silicone block 22. This series of precise designs enables the entire drive component 1 to efficiently convert electrical energy into mechanical energy during operation, providing a continuous source of power for the operation of the air pump.

[0045] Designing the rotating shaft 14 into a V-shape that is symmetrical up and down, and setting the eccentric block 15 at its symmetrical center, has the following advantages: Better balance: The symmetrical V-shaped structure enables the rotating shaft 14 to maintain a good balance during the rotation process, reducing vibration and instability during operation. This balance can reduce noise and wear during mechanical operation and improve the service life and stability of the equipment. Reduce eccentric force: The eccentric block 15 is set at the symmetrical center, which can effectively reduce the influence of eccentric force on the rotating shaft 14 and the drive motor 13. Under normal circumstances, the eccentric block 15 will generate centrifugal force, causing the rotating shaft 14 to generate lateral force, which in turn causes vibration and bearing wear. Through the symmetrical V-shaped design, the eccentric forces offset each other on both sides, which can reduce the burden on the bearings and motors. Improve transmission efficiency: This design can more effectively convert the rotational motion of the motor into the reciprocating motion of the movable component 2, thereby improving transmission efficiency. The V-shaped structure is conducive to transmitting the rotational power of the drive motor 13 more directly to the eccentric block 15, reducing energy loss, and making the air pump more efficient when working. Reduce wear and maintenance costs: Due to the design of balance and reduced eccentric force, the friction and wear between the rotating shaft 14 and other components are reduced. This means that after the equipment has been running for a long time, the bearings and other mechanical parts will wear less, which extends the maintenance cycle of the equipment and reduces maintenance costs. Compact structure: The upper and lower symmetrical V-shaped design makes the entire drive assembly 1 more compact while maintaining efficient operation. This helps to reduce the overall size of the air pump, enhance portability, and make it more suitable for outdoor or emergency use. Reduce the impact of vibration on other components: By accurately setting the position of the eccentric block 15, the impact of vibration on other components can be minimized, thereby avoiding problems such as loose bolts and seal failure caused by vibration, thereby improving the reliability of the entire machine.

[0046] like Figure 5 As shown, the movable assembly 2 is composed of a movable disk 21, a silicone block 22, a cross 23 and a matching block 24, and the overall design is compact and the matching is precise. The movable disk 21 is installed on the side of the driving assembly 1 as the basic support structure of the entire movable assembly 2. The silicone block 22 is tightly attached to the side of the movable disk 21. Driven by the movable disk 21, the silicone block 22 can open and close at an inclined angle, thereby changing the volume of the internal compression cavity 221 to achieve the purpose of inhaling and compressing air.

[0047] A cross 23 is installed above the silicone block 22. The design of the cross 23 helps stabilize the silicone block 22 so that it maintains a precise motion trajectory during operation. A matching block 24 is fixed at the center of the cross 23. The existence of the matching block 24 enables good coordination between the drive component 1 and the movable component 2. The matching block 24 converts the rotational motion generated by the drive component 1 into the reciprocating motion of the silicone block 22 through interaction with the eccentric block 15, ensuring the efficient operation of the air pump. This series of designs enables the movable component 2 to play a key role in the inflation process, ensuring the performance and efficiency of the air pump.

[0048] There are 3 to 6 silicone blocks 22 installed in a circular array on the side of the movable plate 21. The cross 23 can control the expansion and contraction of the silicone block 22, so that the volume of the cavity inside the silicone block 22 changes.

[0049] like Figure 6 As shown, the silicone block 22 has an ingenious structural design and includes three main parts: a compression cavity 221, a positioning column 222 and a clamping ring 223. The compression cavity 221 is located inside the silicone block 22 and is the key area for the air pump to compress air. Driven by the movable component 2, the volume of the compression cavity 221 changes continuously to achieve the suction and compression of air. A positioning column 222 is provided at the lower part of the silicone block 22. The function of the positioning column 222 is to provide a fixed support point for the silicone block 22 to ensure its stability during operation and prevent displacement or shaking.

[0050] A snap ring 223 is installed on the positioning column 222, which plays a role of stabilization and locking. The radius of the snap ring 223 is precisely set to 1.2 times the radius of the positioning column 222. This design provides appropriate tightening force to ensure that the silicone block 22 will not fall off or loosen due to vibration or pressure changes during operation. At the same time, the size ratio between the snap ring 223 and the positioning column 222 also ensures the flexibility of the silicone block 22, allowing it to smoothly change the tilt angle, thereby effectively changing the volume of the compression cavity 221 and achieving an efficient air compression and release process.

[0051] like Figure 7 As shown, the structure of the exchange component 3 is composed of a fixed disk 31, an exchange port 32, a fixed ring 33, a first control pad 34 and a second control pad 35. The overall design is intended to achieve effective control of air flow. The fixed disk 31 is installed on the side of the movable component 2 as the basic support part of the exchange component 3, providing a stable support for the entire system. The exchange port 32 is located on the surface of the fixed disk 31 and is a channel for air circulation. Through it, air can smoothly enter and leave the compression cavity 221, thereby achieving the functions of inflation and deflation.

[0052] The side of the fixed disk 31 is equipped with a fixing ring 33 to ensure the tight connection between the components and prevent loosening or leakage during operation. This fixing ring 33 also enhances the overall stability of the exchange component 3, ensuring that the components can maintain normal operation under high pressure and high speed operation. The No. 1 control pad 34 is installed on the side of the fixed disk 31 to adjust and guide the air flow. It ensures that the air can flow along a predetermined path and improve the efficiency of the air pump. The No. 2 control pad 35 is located in the exchange port 32 and is specifically responsible for finely controlling the inlet and outlet of the air flow. By adjusting the position and angle of the No. 2 control pad 35, the size and flow rate of the air pressure can be effectively controlled to ensure that the air remains stable and controllable during the compression process of the silicone block 22. This design enables the air pump to maintain good performance in different environments and conditions, ensuring an efficient and safe inflation process.

[0053] The control pad No. 1 34 and the control pad No. 2 35 are both made of soft materials. This material selection helps to enhance the sealing performance of the components and ensure that there will be no air leakage during the process of compressing and releasing the air. The control pad No. 2 35 is designed to be circular. This special shape can more flexibly adjust the flow of air, allowing the air to pass through the exchange port 32 more smoothly. To ensure a precise fit, the outer diameter of the control pad No. 1 34 is exactly the same as the inner diameter of the fixed ring 33. This design allows the control pad No. 1 34 to be firmly installed inside the fixed ring 33 to avoid displacement during operation. At the same time, the diameter of the control pad No. 2 35 is the same as the diameter of the exchange port 32, ensuring that the control pad No. 2 35 can fit tightly against the exchange port 32, thereby effectively controlling the in and out of air.

[0054] like Figure 8 As shown, the fixing ring 33 includes three parts: a ring body 331, a support block 332 and a mounting pin 333. The ring body 331 is the main part of the fixing ring 33, which is responsible for providing fixing and supporting functions. It is located in the middle of the exchange port 32 to ensure that the connection with the exchange port 32 is stable and accurate. The support block 332 is installed on the outer side of the ring body 331, mainly used to enhance the contact surface between the fixing ring 33 and the fixed disk 31, and improve the overall stability. The setting of the support block 332 helps to disperse the pressure and reduce the risk of deformation or damage under high-pressure operation. The mounting pin 333 is fixed on the ring body 331. Through the precise positioning of the mounting pin 333, the tight connection between the fixing ring 33 and other components is ensured to prevent loosening or falling off during use, thereby ensuring the stability and reliability of the entire air pump system.

[0055] like Fig. 9As shown, the sealing assembly 4 includes three main parts: a sealing ring 41, a dustproof frame 42 and an air outlet 43, which are intended to ensure the sealing and air circulation of the air pump. The sealing ring 41 is installed on the side of the exchange assembly 3, and it plays a sealing role to prevent air leakage during compression and discharge. The dustproof frame 42 is installed inside the sealing ring 41. The purpose of the dustproof frame 42 is to protect the internal components from the invasion of external dust and impurities, thereby ensuring the long-term stable operation of the air pump. The side of the dustproof frame 42 is equipped with a layer of dustproof net, which effectively blocks the entry of tiny particles and keeps the internal environment clean. The air outlet 43 is arranged in the middle of the sealing ring 41 and communicates with the air outlet pipe 6 to ensure that the compressed air can flow out smoothly and be delivered to the equipment that needs to be inflated. The overall design effectively improves the working efficiency and reliability of the air pump.

[0056] During operation of the present invention, a button battery or other type of power supply component is arranged in the installation cavity 12. The main function of the power supply component is to provide the necessary power for the drive motor 13. When the user starts the air pump, by turning on the power switch, the current will flow into the drive motor 13, so that it starts to operate. The drive motor 13 is the power source of the air pump, and its function is to convert electrical energy into mechanical energy and drive the rotating shaft 14 to rotate.

[0057] The rotating shaft 14 is designed as an eccentric structure, which means that an eccentric force is generated during its rotation, thereby driving the relevant components to move. The eccentric block 15 is provided to improve the stability of the system. By changing the rotation center of the rotating shaft 14, the eccentric block 15 can effectively reduce the vibration that may be generated by the eccentric rotation. This design ensures that the air pump remains stable during operation, reduces noise, and extends the service life of the equipment.

[0058] One end of the rotating shaft 14 is connected to the cross 23. As an important connecting component, the cross 23 transmits the rotational motion of the rotating shaft 14 to the silicone block 22. The design of the cross 23 enables the rotational motion to be effectively converted into mechanical motion, thereby driving the silicone block 22 to compress and recover. A compression cavity 221 is provided inside the silicone block 22, and its volume changes continuously with the movement of the silicone block 22. When the silicone block 22 is compressed, the volume of the cavity decreases and the air is compressed; when the silicone block 22 recovers, the volume of the compression cavity 221 increases, forming a negative pressure, thereby inhaling outside air.

[0059] In this process, air enters from the exchange port 32, which is designed to guide the air to the inside of the fixed disk 31. The fixed disk 31 is provided with a fixed ring 33, and the middle gap of the fixed ring 33 allows the compressed air to be discharged smoothly. The compressed air is discharged through the air outlet 43, which is connected to the air outlet pipe 6, and the air outlet pipe 6 is responsible for conveying the pressurized air to external equipment or inflatable objects.

[0060] In addition, the first control pad 34 is installed on the mounting pin 333. Its design ensures that the gas can only enter the interior of the fixed disk 31 from the outside, preventing gas backflow or leakage. At the same time, the second control pad 35 is installed on the reverse side of the fixed disk 31, and is specifically responsible for discharging the gas from the interior of the fixed disk 31 to the air outlet 43. The coordinated use of these two control pads ensures the accuracy of the air flow path of the air pump, improves the inflation efficiency, and maintains the stability and reliability of the inflation process. The overall design enables the air pump to efficiently and smoothly complete the air compression and discharge tasks during operation.

[0061] A dustproof net is provided inside the dustproof frame 42, which can effectively intercept dust, debris and tiny particles that enter the air pump. If these debris enter the air pump, they may cause wear, blockage or damage to the components, thereby affecting the performance and service life of the air pump. The dustproof net ensures the normal operation of the air pump by keeping the internal environment clean. The design of the dustproof frame 42 not only provides a physical barrier, but also stabilizes the structure to prevent external impacts from damaging internal components. The air pump may encounter vibrations or slight impacts during use. The dustproof frame 42 can absorb these impact forces and protect the internal precision components from damage.
