[0034] In the maintenance and care of various types of tires, ensuring the correct air pressure is crucial for ensuring driving safety, improving fuel efficiency, and prolonging tire service life. Whether it is a bicycle, motorcycle, car, or other types of vehicles, regular check and adjustment of tire air pressure is an important part of maintaining vehicle performance. Traditionally, air pump equipment is usually equipped with plus-minus buttons, which users need to turn on first, and then manually press these buttons to set the required tire pressure value. However, users need to know or query the optimal air pressure value for their tires in advance, and manually adjust it through mechanical buttons on the air pump, making the process of inflating tires by users more cumbersome.

[0035] In view of this, please refer to Figure 1 , Figure 3 and Figure 4 , the present application proposes an inflation system 10, which comprises a magnetic field strength adjustable magnet 100 and an air pump device 200, the magnetic field strength of the magnet 100 corresponds to the target tire pressure value of the tire to be inflated; the air pump device 200 comprises an air pump body 210 and a Hall component 220, the Hall component 220 is electrically connected to the air pump body 210, the Hall component 220 is configured to detect the magnetic field strength of the magnet 100, the air pump body 210 is configured to determine the corresponding target tire pressure value according to the magnetic field strength detected by the Hall component 220, so that the air pump body 210 inflates the tire to be inflated according to the target tire pressure value. In this way, the inflation system 10 of the present application associates the magnetic field strength adjustable magnet 100 with the target tire pressure value of the tire to be inflated, and detects the magnetic field strength by using the Hall component 220 provided in the air pump device 200, realizes the automatic identification and setting of the target tire pressure value, without the need for users to manually set the target tire pressure value through mechanical buttons, making it more convenient for users to inflate tires, thereby helping to significantly improve the convenience, accuracy and intelligent level of the inflation process.

[0036] It can be understood that the user places or connects the magnet 100 with a specific magnetic field strength near or to the inflator device 200, and the inflator system 10 can collect the magnetic field signal through the Hall component 220 and determine the target tire pressure value of the tire to be inflated according to the preset magnetic field-tire pressure mapping relationship. Subsequently, the inflator body 210 performs the inflation operation according to the target tire pressure value and stops when the set pressure is reached, thereby completing an efficient and accurate inflation process. Among them, the user can magnetize the magnet according to the target tire pressure value of the tire to be inflated.

[0037] In addition, the magnet 100 can be configured with a specific magnetic field strength according to different types of tires; the Hall component 220 has high sensitivity and stability, and can accurately identify small changes in the magnetic field, ensuring the accuracy of tire pressure identification. At the same time, the entire identification process does not require external communication or complex software interaction, and the system response speed is fast, which is suitable for various portable or fixed inflator devices.

[0038] Moreover, the magnet 100 as an information carrier, its magnetic field strength is customized according to different types of tires and their recommended tire pressure values. For example, when purchasing a new tire, the user can obtain a magnet 100 that has been precisely magnetized, and the magnetic field strength of the magnet corresponds to the optimal tire pressure value of the tire. When the tire needs to be replaced or the tire pressure needs to be adjusted, the corresponding magnet 100 part can be replaced to achieve quick matching without the need to reconfigure the inflator device 200. This design greatly simplifies the user's operation steps and improves the user experience.

[0039] Please refer to Figure 1 and Figure 3 In some embodiments, the inflator system 10 further comprises a valve cap 300, and the magnet 100 is arranged on the valve cap 300, and the valve cap 300 is adapted to the tire to be inflated.

[0040] The valve cap 300 is used to be installed or connected on the tire valve, and plays a sealing and protection role, and also serves as a carrier of magnetic field information to provide the basis for identifying the target tire pressure value for the inflator device 200.

[0041] In this way, by integrating the magnet 100 into the valve cap 300, when the user dismounts the valve cap 300 and places it near or close to the inflator device 200, the Hall component 220 in the inflator device 200 can detect the magnetic field strength of the magnet 100 and determine the corresponding target tire pressure value. Since different types of tires have different recommended tire pressure ranges, the corresponding valve cap 300 can be configured with a magnet 100 with different magnetic field strengths to achieve automatic identification and accurate inflation for various tires.

[0042] In addition, the standard accessory, the air cap 300, in the existing tire maintenance process is fully utilized, without additional operation steps or complex components, the intelligent transmission of tire pressure information is realized. The user only needs to complete the regular disassembly of the air cap 300 action in the use process, which can trigger the tire pressure setting process, greatly simplifying the human-computer interaction logic, and improving the overall operation efficiency.

[0043] Moreover, the air cap 300 and the magnet 100 are fixedly assembled, ensuring the stable output of the magnetic field signal, avoiding recognition errors caused by external interference. The embodiment not only enhances the practicability of the system, but also has good compatibility, and is suitable for various bicycles, electric bicycles, motorcycles, cars and other tire systems equipped with air caps 300.

[0044] In some embodiments, the magnet 100 is arranged in the air cap 300. The magnet 100 is arranged inside the air cap 300. The air cap 300 is used to be detachably mounted on the tire valve, realizing the traditional sealing and dustproof function, and also serving as a carrier of tire pressure preset information, and transmitting the corresponding magnetic field signal to the inflator device 200 through the embedded magnet 100 inside.

[0045] In this way, the magnet 100 is arranged inside the air cap 300, which helps to protect the magnet 100 from external environment, avoiding the change of the magnetic field caused by dust, moisture or mechanical impact, so as to ensure the stability and detection accuracy of the magnetic field signal. In addition, this embedded structure design does not affect the appearance integrity of the air cap 300, and does not need to change the original operation habit of the user. The user only needs to unscrew the air cap 300 as usual and place it close to the sensing area of the inflator device 200, which can trigger the tire pressure recognition process.

[0046] Further, different types of tires correspond to different recommended tire pressure values, and the magnet 100 inside the air cap 300 can be customized according to actual needs, so that the magnetic field strength and the target tire pressure value form a one-to-one correspondence. For example, the air cap 300 suitable for mountain bikes is embedded with a low magnetic field strength magnet 100, and the air cap 300 suitable for road bikes or electric motorcycles is respectively configured with a magnet 100 of corresponding strength. In this way, no matter what type of tire the user uses, the inflator device 200 can accurately identify the magnetic field strength of the connected air cap 300 through the Hall component 220, and automatically set the matching inflation pressure value.

[0047] Please refer to Figure 2 and Figure 3In some embodiments, the inflator pump device 200 further comprises a housing 230, which is provided with a receiving space 231, and the inflator pump body 210 and the Hall assembly 220 are arranged in the receiving space 231. The housing 230 serves as the main external structure of the inflator pump device 200, not only protecting the internal components, but also providing good grip and portability for user operation.

[0048] The receiving space 231 is arranged inside the housing 230, and its shape and size are designed according to the actual structure of the inflator pump body 210 and the Hall assembly 220, to ensure stable installation of each component in the housing 230, and to maintain good electrical connection and mechanical support. The Hall assembly 220 is arranged near the outer wall of the housing 230, so that when the user brings the valve cap 300 close to or in contact with the housing 230, the magnetic field signal of the magnet 100 can be accurately detected. This layout improves the sensitivity and stability of magnetic field recognition, helping to improve the response speed and accuracy of the overall system.

[0049] In addition, the housing 230 can be provided with an adsorption area or an induction window for positioning the valve cap 300, by embedding a metal sheet or other magnetic material enhancement structure at the corresponding position of the housing 230, so that the valve cap 300 can be adsorbed on the surface of the housing 230 in a stable posture, further optimizing the reading effect of the Hall assembly 220 on the magnetic field. This design not only enhances the reliability of the system operation, but also improves the user's convenience.

[0050] Please refer to Figure 1 , Figure 2 and Figure 3 In some embodiments, the side of the housing 230 away from the receiving space 231 is provided with a mounting hole 232, and part of the valve cap 300 is embedded in the mounting hole 232. In this way, not only is the temporary fixation between the valve cap 300 and the inflator pump device 200 achieved, but also physical support and spatial positioning for stable transmission of the magnetic field signal are provided. The mounting hole 232 can be a blind hole.

[0051] The mounting hole 232 is arranged on the outer surface of the housing 230, and its shape and size are adapted to the external contour of the valve cap 300, so that the valve cap 300 can be accurately aligned and stably embedded during the adsorption or insertion process. When the user removes the valve cap 300 from the tire, it can be directly inserted into the mounting hole 232, so that the magnet 100 and the Hall assembly 220 maintain the optimal induction distance, thereby ensuring that the inflator pump device 200 can quickly and accurately identify the corresponding tire pressure preset value.

[0052] Further, in order to enhance the connection stability between the nozzle cap 300 and the shell 230, a magnetic material or a metal sheet can be arranged around the mounting hole 232 to realize magnetic attraction fixation with the magnet 100 inside or on the surface of the nozzle cap 300. This structural design helps to improve the reliability of magnetic field detection on the one hand, and on the other hand, prevents the nozzle cap 300 from accidentally falling off during use, thereby improving the safety and convenience of the overall operation.

[0053] In addition, the position of the mounting hole 232 is preferably arranged in an area of the shell 230 that is convenient for operation and observation, such as above or on the side of the hand-held part of the shell 230, so that the user can quickly complete the placement and use of the nozzle cap 300, while not affecting the overall aesthetics and holding comfort of the inflator pump device 200.

[0054] Please refer to Figure 3 and Figure 4 In some embodiments, the inflator pump body further comprises an iron sheet 240 arranged near the mounting hole 232. The main function of the iron sheet 240 is to form a magnetic attraction cooperation with the magnet 100 in the nozzle cap 300, thereby realizing the stable connection between the nozzle cap 300 and the inflator pump device 200.

[0055] Specifically, when the user removes the nozzle cap 300 with the magnet 100 from the tire, it is partially inserted into the mounting hole 232 on the shell 230. At this time, the iron sheet 240 arranged near the mounting hole 232 generates a strong magnetic attraction force with the magnet 100, so that the nozzle cap 300 can be firmly attracted to the inflator pump device 200, avoiding falling off due to shaking or accidental touch during operation. This magnetic fixation method not only has a simple structure and convenient operation, but also does not require additional buckles or other mechanical locking mechanisms, simplifying product design and improving user convenience.

[0056] In addition, the presence of the iron sheet 240 also helps to enhance the stability of the magnetic field transmission path and improve the detection accuracy of the Hall component 220 on the magnetic field strength of the magnet 100. Since the iron sheet 240 has good magnetic conductivity, it can guide the magnetic force lines to act more concentratedly on the sensing area of the Hall component 220, thereby improving the sensitivity and consistency of the system in identifying the preset tire pressure value.

[0057] Further, the iron sheet 240 can be manufactured by stamping forming process and installed inside the shell 230 near the mounting hole 232 by insert molding, bonding or screw fixation, etc. Its shape and size are optimized according to the actual space layout to ensure that it can effectively attract the nozzle cap 300 without affecting the normal assembly and operation of other functional components.

[0058] In some embodiments, the iron sheet 240 and the magnet 100 are located on opposite sides of the shell 230 along the axial direction of the mounting hole 232, which helps to improve the adsorption strength of the magnet 100 to the iron sheet 240, so that the air cap 300 is more stably adsorbed on the inflator device 200, avoids falling off due to vibration or accidental touch, and improves the stability and safety during use.

[0059] In addition, it also helps to concentrate the magnetic force lines through the shell 230 and act on the sensing area of the Hall assembly 220, thereby improving the accuracy of tire pressure identification. Since the iron sheet 240 has good magnetic conductivity, the magnetic circuit path formed by the iron sheet 240 and the magnet 100 is more concentrated, reducing the loss of the magnetic field, and ensuring that the Hall assembly 220 can more stably and accurately read the magnetic field strength of the magnet 100.

[0060] In some embodiments, the Hall assembly 220 includes a Hall sensor 221 and a circuit board 222, and the Hall sensor 221 is arranged on the circuit board 222, and the circuit board 222 is electrically connected to the inflator body 210.

[0061] The circuit board 222 is further electrically connected to the inflator body 210 to realize the collection, processing of tire pressure identification signals and control of the working state of the inflator.

[0062] Specifically, the Hall sensor 221 is used as a magnetic field detection element to sense the magnetic field strength generated by the magnet 100 and convert the magnetic field signal into an electrical signal output. The Hall sensor 221 is fixed on the circuit board 222 by surface mounting or other reliable electronic assembly process, which ensures good stability and anti-interference ability during use. The circuit board 222 bears the core functions of signal processing, data transmission and power management, and establishes electrical connection with the controller, driving motor and other components in the inflator body 210, so as to realize the complete control logic from magnetic field identification to automatic inflation.

[0063] In actual operation, when the user embeds the air cap 300 with the magnet 100 into the mounting hole 232 on the shell 230, the magnetic field generated by the magnet 100 acts on the sensing area of the Hall sensor 221. The circuit board 222 determines the current magnetic field strength according to the voltage signal output by the Hall sensor 221, and determines the corresponding target tire pressure value through the preset magnetic field-tire pressure mapping relationship. Subsequently, the circuit board 222 transmits the target pressure value to the control system of the inflator body 210, and the inflator body 210 automatically starts and performs inflation operation until the set tire pressure is reached.

[0064] Further, the circuit board 222 can also be integrated with filtering circuits, amplification circuits, analog-to-digital conversion modules, and other functional units to improve the accuracy and stability of the detection signal of the Hall sensor 221. At the same time, the circuit board 222 is provided with a communication interface to support data interaction with an external display module, a battery management system, or a wireless connection module, thereby expanding the intelligent application capabilities of the system.

[0065] In some embodiments, the Hall sensor 221 is arranged close to the mounting hole 232 to ensure that it can efficiently and accurately detect the magnetic field strength generated by the magnet 100 in the air cap 300 inserted into the mounting hole 232. This arrangement fully considers the transmission path and attenuation characteristics of the magnetic field signal, which helps to improve the response speed and detection accuracy of the tire pressure identification system.

[0066] Specifically, the Hall sensor 221 as a magnetic field sensing element, its detection sensitivity is closely related to the distance between the measured magnet 100. By arranging the Hall sensor 221 on the circuit board 222 close to the mounting hole 232, the sensor is as close as possible to the magnetic field area where the magnet 100 is located, thereby significantly enhancing its sensing ability to the change of the magnetic field. When the user inserts the air cap 300 with the magnet 100 into the mounting hole 232, the shortest magnetic induction line path is formed between the magnet 100 and the Hall sensor 221, so that the sensor can quickly collect stable magnetic field signals.

[0067] Further, in order to optimize the magnetic field detection effect, the Hall sensor 221 can be arranged below or below the side of the circuit board 222 opposite to the center axis of the mounting hole 232, and the space layout is optimized in combination with the structure of the shell 230 to ensure that the magnet 100 can maintain the best sensing distance with the sensor after being inserted. At the same time, a shielding layer or a magnetic conductive material can be arranged around the Hall sensor 221 to reduce the influence of external interference magnetic field and improve the stability and consistency of the system operation.

[0068] In addition, since the Hall sensor 221 is arranged close to the mounting hole 232, the entire tire pressure identification process does not require the user to perform complex operations or additional action triggering, and only the regular air cap 300 placement action is required to automatically start the inflation process, thereby greatly improving the intelligent level and use convenience of the product.

[0069] In some embodiments, the air cap 300 is gap-fitted with the mounting hole 232. This fitting means that after the air cap 300 is inserted into the mounting hole 232, a certain gap is reserved between the outer wall of the air cap 300 and the inner wall of the mounting hole 232 to ensure that the air cap 300 can be smoothly inserted or taken out without applying a large force, while maintaining a relatively stable spatial position during the magnetic field detection process.

[0070] The gap fit design helps improve the convenience of user operation and the flexibility of system adaptation. When the user removes the valve cap 300 from the tire valve, it can be directly aligned with the mounting hole 232 on the shell 230 of the inflator device 200 and easily inserted therein without worrying about the difficulty of plugging due to size error or assembly deviation. This structural design not only reduces the processing precision requirement of the product, but also improves the universality between different batches and different types of valve caps 300 and mounting holes 232.

[0071] Further, the gap fit also provides a stable physical space environment for the magnetic field transmission between the magnet 100 and the Hall sensor 221. Even if the valve cap 300 has a slight offset in the mounting hole 232, it will not significantly affect the detection effect of the Hall component 220 on the magnetic field strength, thereby ensuring the accuracy and consistency of the tire pressure identification.

[0072] In some embodiments, the inflator body 210 is used to deliver compressed gas to the tire to be inflated and automatically control the start and stop of the inflation process according to the target tire pressure value. The inflator body 210 includes a motor, a pump assembly, a pressure sensor, a controller, and corresponding electrical connection structures, which work together to achieve intelligent detection and accurate adjustment of the tire pressure.

[0073] The motor is a driving power source, usually a direct-current brushless motor or a micro permanent magnet motor, which has the advantages of small size, high efficiency, and low noise, and can meet the requirements of power consumption and endurance of portable devices. The output shaft of the motor is connected with the pump assembly to drive the piston or diaphragm reciprocating motion, thereby sucking external air and outputting it to the inside of the tire after compression.

[0074] The pump assembly is composed of an air inlet valve, an air outlet valve, a cylinder, and a sealing element, etc., which is responsible for converting the mechanical energy provided by the motor into gas pressure energy. Its structural design fully considers the sealing and durability to ensure stable gas supply performance under the conditions of long-time continuous operation or frequent start-stop.

[0075] The pressure sensor is arranged near the air outlet of the pump and is used to monitor the current pressure value inside the tire in real time and feed back the collected pressure signal to the controller. The controller compares the data fed back by the pressure sensor with the target tire pressure value, and when the target pressure is reached, the motor stops running to complete the inflation operation; if the detected pressure does not meet the requirements, the inflation state is maintained until the set requirements are met.

[0076] In addition, the inflator pump body 210 is electrically connected with the Hall assembly 220 through the circuit board 222, receives the magnetic field signal identified and converted by the Hall sensor 221, and analyzes the corresponding target tire pressure value. The control logic does not require manual input of parameters by the user, and can realize full-process automation from tire pressure identification to inflation execution, significantly improving the intelligent level and use convenience of the product.

[0077] In some embodiments, the inflator system 10 further comprises a magnetizing device configured to perform a magnetizing operation on the magnet 100, thereby providing a technical means for the user to flexibly adjust the magnetic field strength of the magnet 100, so that the magnet 100 can be matched with the recommended tire pressure value corresponding to different types of tires according to actual application requirements.

[0078] Specifically, the magnetizing device includes a magnetizing coil, a control circuit, and a power module. The magnetizing coil is arranged around the magnet 100 and is used to generate a high-strength magnetic field in a powered state, thereby changing the internal magnetic domain arrangement state of the magnet 100 and obtaining a magnetization effect with a specific direction and strength. The control circuit is used to adjust the current size and duration applied to the magnetizing coil to accurately control the magnetic field strength finally reached by the magnet 100. The power module provides stable power support for the entire magnetizing process, ensuring the consistency and repeatability of the magnetizing results.

[0079] In this way, by introducing the magnetizing device, the user can perform targeted magnetizing treatment on the magnet 100 according to the type of the tire to be inflated and its recommended tire pressure value. For example, when a tire with a higher recommended tire pressure value is replaced, the user can place the magnet 100 in the magnetizing device and set the corresponding magnetizing parameters, so that the magnet 100 obtains a higher magnetic field strength; conversely, the magnetic field strength can be reduced to adapt to the tire with low tire pressure requirements. This flexible magnetic field adjustment mechanism significantly improves the universality and application range of the system.

[0080] In addition, the magnetizing device can be integrated inside the inflator pump device 200 or provided as a separate accessory for the user to use. If an integrated design is adopted, the target tire pressure level can be selected through the operation interface, and the magnetizing setting of the magnet 100 can be automatically completed by the system; if an external form is adopted, it is convenient for the user to flexibly deploy between different devices, improving the maintainability and expansion capability of the overall system.

[0081] Please refer to Figure 5 The present application also provides an inflating method applied to the inflator system 10 of any of the above embodiments. The inflator pump body 210 is provided with a controller electrically connected to the Hall assembly 220. The controller is used to perform the following method, which includes steps 010, 020, and 030.

[0082] Step 010: Detect the magnetic field strength of the magnet 100 by the Hall component 220.

[0083] Specifically, when the user places the component (e.g. the valve cap 300) carrying the magnet 100 close to or inserts it into the mounting hole 232 of the inflator 200, the Hall component 220 begins to sense the magnetic field generated by the magnet 100. The Hall sensor 221 in the Hall component 220 outputs a voltage signal proportional to the magnetic field strength in response to the magnetic field, thereby achieving accurate collection of the magnetic field strength.

[0084] This step can also be completed by a non-contact detection method, without the user needing to perform complex operations or additional input parameters, and only a regular placement action is needed to trigger the detection process. The Hall component 220 converts the collected magnetic field signal into a digital electrical signal and transmits it to the controller as basic data for subsequent identification of the target tire pressure value.

[0085] Step 020: Determine the corresponding target tire pressure value based on the detected magnetic field strength.

[0086] Specifically, the Hall component 220 converts the collected magnetic field strength signal into an electrical signal and transmits it to the controller. The controller has a pre-set mapping relationship between the magnetic field strength and the tire pressure value, which can be stored in the storage module of the controller through experimental calibration or pre-shipment writing. The controller looks up the matching target tire pressure value in the mapping relationship according to the received magnetic field strength data and takes it as the set pressure value for this inflation operation.

[0087] In order to improve the recognition accuracy and system adaptability, the controller can also perform filtering processing, temperature compensation, and non-linear correction operations on the original signal output by the Hall component 220 to eliminate the influence of environmental interference or sensor errors. In addition, the controller supports switching functions for multiple mapping relationships, such as setting different magnetic field-tire pressure correspondence tables for different types of tires (such as bicycles, motorcycles, cars, etc.), thereby achieving more extensive application adaptation capabilities.

[0088] Further, this step also includes an abnormality identification mechanism. If the controller detects that the magnetic field strength is outside the pre-set range or does not detect a valid magnetic field signal, it can be determined that the magnet 100 is abnormal or not placed correctly, and the user is prompted to check through the display module or sound, preventing false identification from causing incorrect inflation.

[0089] Step 030: Inflate the tire to be inflated according to the target tire pressure value.

[0090] Specifically, the controller compares the target tire pressure value obtained with the current tire air pressure fed back by the pressure sensor in real time, and generates a corresponding control signal to start or stop the air pump body 210 to work. When it is detected that the current tire air pressure is lower than the target tire pressure value, the controller drives the motor to operate, and the air pump assembly delivers compressed air to the inside of the tire; when the tire air pressure reaches the target value, the controller immediately issues an instruction to stop the motor from running, thereby completing a complete and accurate inflation process.

[0091] Further, during the inflation process, the inflation system 10 continuously collects tire internal air pressure data through the pressure sensor and feeds it back to the controller in real time, forming a closed-loop control logic. This design ensures that even in the presence of interference factors such as changes in ambient temperature and fluctuations in air pump output, high inflation accuracy and stability can be maintained.

[0092] In addition, in order to improve user experience and safety, the system also has an overpressure protection mechanism. If the tire air pressure exceeds the set target value by a certain threshold during the inflation process, the controller can judge it as an abnormal situation and automatically cut off the air source or prompt the user to check the tire status, preventing the tire from being damaged or causing safety hazards due to overinflation.
