[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] like Figures 1 to 3 As shown, this application provides an air inflator for inflating tires. The tire is equipped with an information storage device for storing tire information, which includes at least the tire's inflation pressure information. The air inflator for inflating tires includes a housing, an air pump assembly, an inflation hose 17, a PCB board 2, and an information reading device 4. The housing has a receiving cavity and an air inlet 11 and an air outlet 14 communicating with the receiving cavity. Preferably, the housing includes an inner shell 12 and an outer shell 18, with the outer shell 18 fitted onto the inner shell 12. The inner shell 12 has a receiving cavity and an air inlet 11 and an air outlet 14 communicating with the receiving cavity. The outer shell 18 has an air inlet 11 and an air outlet 14 communicating with the inner shell 12. The air outlet 14 corresponds to the air inlet 19 and the air outlet 14; the air pump assembly is located inside the receiving cavity; the input end of the air pump assembly is connected to the air inlet 11, and the output end of the air pump assembly is connected to the air outlet 14; one end of the inflation tube 17 is connected to the air outlet 14 and is connected to the output end of the air pump assembly; the other end of the inflation tube 17 is located outside the receiving cavity and is used to connect to the inflation connector 10; the PCB board 2 is located on the housing and is electrically connected to the air pump assembly; the information reading device 4 is located on the housing and is electrically connected to the PCB board 2; the information reading device 4 is used to read the inflation pressure information stored in the information storage device of the tire to be inflated.

[0037] Among them, such as Figures 1 to 3 As shown, the housing, serving as the main structure of the air pump, provides space to accommodate other components and protects the internal components from external environmental influences. The housing has a cavity for housing core components such as the air pump assembly and PCB board 2. The air pump assembly is the core power component of the air pump, responsible for compressing external air and outputting it through the air outlet 14. The input end of the air pump assembly is connected to the air inlet 11 of the housing for drawing in external air. The output end of the air pump assembly is connected to the air outlet 14 of the housing for outputting compressed air. The air pump assembly, controlled by the PCB board 2, adjusts the inflation pressure and inflation volume based on the tire's inflation pressure information. The inflation hose 17 is used to deliver compressed air to the tire's inflation connector 10. One end of the inflation hose 17 is connected to the air outlet 14 of the housing and communicates with the output end of the air pump assembly. The other end of the inflation hose 17 is located outside the housing and is used to connect to the tire's inflation connector 10 to achieve air delivery. The PCB board 2 is the control center of the air pump, responsible for processing the data acquired by the information reading device 4 and controlling the operation of the air pump assembly. Specifically, PCB board 2 is electrically connected to the air pump assembly, controlling the start / stop of the air pump and the inflation pressure based on the tire's inflation pressure information. PCB board 2 is also electrically connected to the information reading device 4, receiving and processing the tire's inflation pressure information. The information reading device 4 wirelessly communicates with the information storage device on the tire to obtain the tire's inflation pressure information. The information reading device 4 transmits the read inflation pressure information to PCB board 2, and PCB board 2 controls the operation of the air pump assembly based on this information. That is, when the user brings the air pump close to the tire, the information reading device 4 reads the inflation pressure information from the tire's information storage device. The information reading device 4 transmits the inflation pressure information to PCB board 2, and PCB board 2 sets the target inflation pressure based on this information. PCB board 2 starts the air pump assembly, which draws in and compresses air through the air inlet 11, and delivers the compressed air to the tire through the air outlet 14 and the inflation hose 17. When the target pressure is reached, the air pump assembly automatically stops working. After inflation is complete, the user disconnects the inflation hose 17 from the tire, completing the inflation process. With the cooperation of the information reading device 4 and the PCB board 2, the inflator can read the tire inflation pressure information and inflate the tire without manual intervention.

[0038] As a preferred embodiment, such as Figures 1 to 4As shown, the information storage device is an NFC storage device, preferably an NFC tag; the information reading device 4 is an NFC chip, which is used to read the inflation pressure information of the NFC storage device. In this embodiment, NFC technology is used as a means of information storage and reading. Specifically, the user only needs to bring the air pump with the NFC chip close to the NFC storage device on the tire, and with a light touch, the NFC chip can quickly read the tire pressure information of the inflation target; the obtained information is then transmitted to the PCB board 2. After receiving the tire pressure information provided by the NFC chip, the PCB board 2 automatically sets the target inflation pressure value; next, the air pump assembly starts under the control of the PCB board 2, the sucked-in air is compressed, and the compressed air is delivered to the target that needs to be inflated through the inflation tube 17. The whole process does not require complicated settings by the user. Just bring the air pump close to the NFC tag on the tire and connect it to the inflation connector 10. With a simple "touch" action, the car tire information can be read and the pressure value to be set can be automatically set. Users can directly turn on the device to start inflating the tire. Once the pressure inside the tire reaches the automatically set value, the inflator will automatically shut off, completing the inflation process. This inflator with an NFC chip is suitable for scenarios where tires have NFC tags installed.

[0039] As a preferred embodiment, such as Figures 1 to 3 and Figure 5 As shown, the information storage device is an image storage device. Preferably, the image storage device can be a QR code, barcode, or other text information. The information reading device 4 is an image acquisition device, which is used to acquire the inflation pressure information of the image storage device. Preferably, the image acquisition device can be a camera or a webcam. Specifically, the user brings the air pump close to the tire and takes a picture or scans the tire to acquire image information, which is then transmitted to the PCB board 2. Based on the result identified by the image acquisition device, the tire model and other information are confirmed, and the target inflation pressure value is automatically set. The air pump assembly is started under the control of the PCB board 2 to compress the intake air. The compressed air enters the inflation pipe 17, which delivers the compressed air to the target to be inflated. The entire process does not require complicated settings by the user. The user only needs to bring the air pump close to take a picture or scan the image storage device to confirm the relevant tire information and automatically set the appropriate tire pressure. Inflation can be started immediately upon powering on, saving time and effort. This air pump with a camera or webcam is suitable for scenarios where QR codes, barcodes, or text information are printed on the tires.

[0040] As a preferred embodiment, such as Figure 1 , Figures 3 to 5As shown, the housing is provided with a mounting groove 13, and the inflation tube 17 is inserted through the mounting groove 13 to communicate with the output end of the air pump assembly; wherein, the mounting groove 13 is used to fix one end of the inflation tube 17 to ensure that the inflation tube 17 is stably connected to the output end of the air pump assembly and to prevent the inflation tube 17 from loosening or falling off during use.

[0041] As a preferred embodiment, such as Figure 1 , Figures 3 to 5 As shown, the housing is also provided with a placement groove 15, and the end of the inflation tube 17 away from the mounting groove 13 extends into the placement groove 15. The placement groove 15 is used to place and store the end of the inflation tube 17 away from the mounting groove 13, so that the inflation tube 17 can be neatly stored when not in use, avoiding tangling or damage caused by random placement of the inflation tube 17.

[0042] It is important to note that, such as Figure 1 , Figures 3 to 5 As shown, the mounting slot 13 and the placement slot 15 provide fixed positions for the inflation hose 17 both inside and outside the housing, forming an integrated structure that enhances the overall integrity and aesthetics of the inflatable device. Specifically, during use, the user simply removes the inflation hose 17 from the placement slot 15 and connects it to the tire inflation connector 10. After use, the user stores the inflation hose 17 back in the placement slot 15, keeping the inflatable device tidy. Furthermore, the mounting slot 13 and placement slot 15 secure and store the inflation hose 17, making the overall structure of the inflatable device more compact and reducing the risk of tripping or damage caused by careless placement of the inflation hose 17.

[0043] As a preferred embodiment, such as Figures 1 to 2 As shown, an inflation channel 16 is provided between the output end of the air pump assembly and the inflation pipe 17. The inflation channel 16 has an inflation port, which is positioned away from the mounting groove 13. The inflation channel 16 ensures a tighter connection between the air pump assembly output end and the inflation pipe 17, allowing for smoother flow of compressed air from the air pump assembly output end to the inflation pipe 17, reducing airflow resistance and improving inflation efficiency. Furthermore, the fact that the inflation port is positioned away from the mounting groove 13 prevents airflow from directly impacting the mounting groove 13 or other components within the housing, reducing airflow interference with the internal structure and improving the overall stability of the inflatable device.

[0044] As a preferred embodiment, such as Figures 1 to 2As shown, the air pump assembly includes a piston mechanism 8 and a driver 7. The suction end of the piston mechanism 8 is connected to the air inlet 11, and the inflation end of the piston mechanism 8 is connected to the inflation port. The driver 7 drives the piston mechanism 8 to perform piston movement to inflate the tire through the inflation port. Specifically, the driver 7 drives the piston mechanism 8 to move away from the inflation port, and the suction end of the piston mechanism 8 draws in external air through the air inlet 11. The driver 7 drives the piston mechanism 8 to move towards the inflation port, compressing the drawn-in air. The compressed air is delivered to the inflation port through the inflation end of the piston mechanism 8 and enters the tire through the inflation tube 17. The driver 7 continuously drives the piston mechanism 8 to perform reciprocating motion until the tire reaches the target inflation pressure. That is, the piston mechanism 8 compresses air and delivers it to the inflation port through reciprocating motion, which can quickly inflate the tire and shorten the inflation time. By controlling the piston mechanism 8 through the driver 7, the air pump can accurately adjust the inflation pressure according to the tire inflation pressure information to avoid over-inflation or under-inflation.

[0045] As a preferred embodiment, such as Figures 1 to 2 As shown, the driver 7 includes a motor 71, a gear 72, and a connecting rod 73. The output end of the motor 71 is connected to the input end of the gear 72, the output end of the gear 72 is connected to one end of the connecting rod 73, and the other end of the connecting rod 73 is connected to the piston cylinder of the piston mechanism 8. When the motor 71 starts, its output end drives the gear 72 to rotate. The gear 72 transmits the rotational motion of the motor 71 to the connecting rod 73. The connecting rod 73 converts the rotational motion into linear reciprocating motion, driving the piston cylinder of the piston mechanism 8 to move. The reciprocating motion of the piston cylinder realizes the intake, compression, and discharge of air, completing the inflation process. This enables rapid air compression and delivery, improving inflation efficiency.

[0046] As a preferred embodiment, such as Figures 1 to 2 As shown, the bottom of the housing has a storage cavity for placing the inflation connector 10; the bottom of the housing also has a movable plate 9 corresponding to the storage cavity, the movable plate 9 being connected to the housing via a hinge to open or close the storage cavity. This storage cavity is designed to safely store the inflation connector 10 when not in use, and the user can open or close the storage cavity by flipping the movable plate 9 for easy access to the inflation connector 10.

[0047] As a preferred embodiment, such as Figures 1 to 5 As shown, it also includes a control panel 5, which is located in the housing and electrically connected to the PCB board 2. Users can directly operate the air pump through the control panel 5, such as starting or stopping the inflation pressure, making it more convenient and faster for users to perform various operations when using the air pump.

[0048] As a preferred embodiment, such as Figures 1 to 5 As shown, a display screen 3 is provided on one side of the control panel 5, and the display screen 3 is electrically connected to both the PCB board 2 and the control panel 5. The display screen 3 can display information such as inflation pressure, inflation time, and battery level in real time, allowing users to easily understand the inflation status. Users can also view the operation results in real time through the display screen 3, such as whether the inflation pressure has reached the target value.

[0049] As a preferred embodiment, such as Figures 1 to 5 As shown, it also includes a power module 1, which is located in the receiving cavity and electrically connected to the PCB board 2, providing stable power support for the inflatable bank and ensuring its normal operation. Preferably, the power module 1 can be battery powered, allowing the inflatable bank to be used without an external power source, suitable for outdoor or vehicle-mounted scenarios. Preferably, the housing also has a USB interface 6 to support USB charging or vehicle charging, further improving portability.
