[0022] refer to Figure 1-4 The present application discloses an air pump device, including a shell 1, a high-pressure air pump 2 connected to the cavity wall of a accommodating cavity 11 of the shell 1, a medium-pressure air pump 3 connected to the cavity wall of the accommodating cavity 11, a low-pressure air pump 4 connected to the cavity wall of the accommodating cavity 11, a driving component 7 connected to the cavity wall of the accommodating cavity 11 and used to provide power to the high-pressure air pump 2, the medium-pressure air pump 3 and the low-pressure air pump 4, a control component 5 connected to the cavity wall of the accommodating cavity 11 and used to control the driving component 7, and a power supply 6 connected to the cavity wall of the accommodating cavity 11 and electrically connected to the control component 5. The air supply pipe of the high-pressure air pump 2, the air supply pipe of the medium-pressure air pump 3 and the air supply pipe of the low-pressure air pump 4 all extend to the outer wall of the shell 1 for connecting with the corresponding equipment to be charged.

[0023] The air pump device of the present application integrates a high-pressure air pump 2, a medium-pressure air pump 3 and a low-pressure air pump 4 in a housing 1 to meet various inflation needs. The user selects the required air pump type through the control component 5, and the control component 5 then instructs the drive component 7 to control the corresponding air pump. Among them, the high-pressure air pump 2 is suitable for equipment that requires a larger pressure, such as car tires; the medium-pressure air pump 3 is suitable for applications that require medium pressure, such as kayaks; and the low-pressure air pump 4 is mainly used in situations that require a large flow but not high pressure, such as an inflatable mattress. Through this design, the present application not only simplifies the user's operation process, but also reduces the need to carry multiple air pumps. This integrated design effectively reduces the size and weight of the equipment and increases portability.

[0024] What needs to be explained is:

[0025] Features of the high-pressure air pump 2: The high-pressure air pump 2 is capable of providing pressures up to 150PSI or higher, and is suitable for equipment that requires strict air pressure, such as car tires and bicycle tires; in order to maintain a stable high pressure, the high-pressure air pump 2 is usually designed for low flow output, which helps to more accurately control the inflation process and avoid over-inflation and potential damage. The high-pressure air pump 2 can be a vehicle-mounted air pump.

[0026] Features of the medium-pressure air pump 3: The pressure provided by the compressed air pump is generally around 20PSI, which is suitable for outdoor water sports equipment such as kayaks and paddle boards. Compared with the high-pressure air pump 2, the medium-pressure air pump 3 provides a larger flow rate so that it can be inflated to the required medium pressure more quickly, ensuring efficiency and ease of use. The medium-pressure air pump 3 can be a paddle board air pump.

[0027] Features of the low-pressure air pump 4: The low-pressure air pump 4 provides a low pressure (usually no more than 5PSI), but a large flow rate, which is very suitable for rapid inflation of large-volume items such as air mattresses and swimming rings; the flow rate enables the low-pressure air pump 4 to complete the inflation task of a large volume in a short time, greatly improving the inflation efficiency. The low-pressure air pump 4 can be a pneumatic pump.

[0028] The power source 6 may be a battery.

[0029] The medium-pressure air pump 3 is connected to the air pipe of the medium-pressure air pump 3 through the connecting pipe 8. The air pipe of the medium-pressure air pump 3 is connected to a pressure sensor (not shown in the figure) for real-time monitoring of the air pressure in the air pipe. The pressure sensor is electrically connected to the control component 5. The air pipe of the low-pressure air pump 4 is connected to a valve (not shown in the figure) for controlling the on-off of the air pipe. The valve is electrically connected to the control component 5.

[0030] In the process of using the medium-pressure air pump 3 for inflation, a large flow of gas is required to quickly fill the device to be inflated in the initial stage, so as to quickly expand the device to be inflated to the basic shape. At this time, the control component 5 instructs the valve of the low-pressure air pump 4 to close to prevent gas leakage from the low-pressure air pump 4. At the same time, the low-pressure air pump 4 works to transport gas to the gas pipe of the medium-pressure air pump 3 through the connecting pipe 8, and uses its large flow characteristics to quickly inflate. As the volume of the inflatable device is gradually filled, the pressure sensor monitors the air pressure in the gas pipe of the medium-pressure air pump 3 in real time. When the air pressure reaches the preset threshold required for the start of the medium-pressure air pump 3, the control component 5 automatically switches, turns off the low-pressure air pump 4, and starts the medium-pressure air pump 3 to continue inflating; as the medium-pressure air pump 3 is started, the gas flow decreases and the pressure increases, which is suitable for the inflation stage when the device to be inflated is about to end. During the entire inflation process, the control component 5 adjusts the working state of the switching air pump according to the feedback of the pressure sensor to ensure the efficiency and safety of the inflation process.

[0031] In some embodiments, when the medium-pressure air pump 3 is used, the low-pressure air pump 4 may be used first until the pressure reaches 0.5-0.8 PSI and then switched to the medium-pressure air pump 3 .

[0032] The connecting pipe 8 may also be provided with a valve, so that when the low-pressure air pump is used, the valve in the connecting pipe 8 can be closed by the control component to prevent the airflow of the low-pressure air pump 4 from being output from the air pipe of the medium-pressure air pump 3 through the connecting pipe 8.

[0033] The valve may be a solenoid valve.

[0034] In some embodiments, the low-pressure air pump 4 can not only realize inflation, but also inhale air to realize the storage and compression of swimming rings, inflatable beds, clothes, etc.

[0035] The control component 5 includes a controller 51 connected to the cavity wall of the accommodating cavity 11 and a control panel 52 connected to the outer wall of the shell 1 and electrically connected to the controller 51 . The pressure sensor, valve, power supply 6 and drive component 7 are all electrically connected to the controller 51 .

[0036] The controller 51 is electrically connected to the pressure sensor, valve, power supply 6 and drive assembly 7 to achieve precise control of the air pump. At the same time, the control panel 52 connected to the outer wall of the housing 1 provides the user with an intuitive and easy-to-operate interface, which can be a touch screen or physical buttons, allowing the user to easily select different air pump operation modes and set specific inflation pressures. The user selects the desired air pump type and sets the inflation pressure through the control panel 52, and the controller 51 receives these input instructions and controls the corresponding air pump to start or stop.

[0037] The driving assembly 7 includes a first motor connected to the cavity wall of the accommodating cavity 11 and a second motor 71 connected to the cavity wall of the accommodating cavity 11. The high-pressure air pump 2 and the medium-pressure air pump 3 are connected to the first motor, and the low-pressure air pump 4 is connected to the second motor 72. The first motor 71 and the second motor 72 are all electrically connected to the controller 51.

[0038] The first motor is connected to the high-pressure air pump 2 and the medium-pressure air pump 3, and is used to handle inflation tasks that require higher pressure, such as the inflation of car tires and kayaks. The design of this motor emphasizes high torque and moderate speed to ensure inflation efficiency and stable operation of the equipment while maintaining higher pressure. The second motor 72 is connected to the low-pressure air pump 4 for large flow and low pressure inflation requirements, such as inflatable mattresses or swimming rings. This motor design focuses on high speed and low torque to quickly complete large volume inflation.

[0039] The first motor can be connected to the high-pressure air pump 2 and the medium-pressure air pump 3 at the same time through a gear box, a coupling and other devices.

[0040] The connecting pipe 8 includes a first pipe 81 integrally formed with the air delivery pipe of the medium-pressure air pump 3 and a second pipe 82 integrally formed with the pump body of the low-pressure air pump 4. The first pipe 81 and the second pipe 82 are connected via a flange.

[0041] The shell 1 is a rectangular parallelepiped as a whole, and the high-pressure air pump 2, the medium-pressure air pump 3 and the low-pressure air pump 4 can be arranged on one side of the inner wall of the accommodating chamber 11, so that the air pipe of the high-pressure air pump 2, the air pipe of the medium-pressure air pump 3 and the air pipe of the low-pressure air pump 4 extend from the side wall of the same side of the shell 1, which is convenient for users to use; in addition, the pipe openings of the air pipe of the high-pressure air pump 2, the air pipe of the medium-pressure air pump 3 and the air pipe of the low-pressure air pump 4 can be provided with internal or external threads, which are convenient for threaded connection with the equipment to be charged, and this connection method is more stable.

[0042] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0043] The above is a relatively specific and detailed description of the present application through general description and specific embodiments. It should be understood that, based on the technical concept of the present application, several conventional adjustments or further innovations can be made to these specific embodiments; however, as long as they do not deviate from the technical concept of the present application, the technical solutions obtained by these conventional adjustments or further innovations also fall within the scope of protection of the claims of the present application.
