Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a compressed air pump, an air pump system, a cabin, and a vehicle. Background Technology

[0002] Currently, vehicles are typically equipped with air spring systems, which supply air for purposes such as air conditioning and interior cleaning. However, the functions of current air spring systems are limited. Utility Model Content

[0003] This application provides a compressed air pump, an air pump system, a cockpit, and a vehicle. The compressed air pump includes a first compression mechanism and a second compression mechanism. The compressed air pump can output a first output gas with a first pressure through the first compression mechanism and the second compression mechanism working in parallel for low-pressure air supply, and can output a second output gas with a second pressure through the first compression mechanism and the second compression mechanism working in series for high-pressure air supply. This allows the compressed air pump to not only provide low-pressure air supply but also high-pressure air supply, thereby increasing the variety of air supply targets and enriching its air supply functions.

[0004] In a first aspect, this application provides a compressed air pump. The compressed air pump includes: a housing having an air inlet, a first air outlet, and a second air outlet spaced apart. A first compression mechanism has a first air inlet, a first air outlet, and a second air outlet spaced apart, the first air inlet communicating with the air inlet, and the first air outlet communicating with the first air outlet. A second compression mechanism has a second air inlet, a third air inlet, a third air outlet, and a fourth air outlet spaced apart, the second air inlet communicating with the second air outlet, the third air inlet communicating with the air inlet, the third air outlet communicating with the second air outlet, and the fourth air outlet communicating with the first air outlet. The compressed air pump has a first state and a second state: In the first state, the first air inlet is connected to the air inlet port, the first air outlet is connected to the first air outlet port, the third air inlet is connected to the air inlet port, and the fourth air outlet is connected to the first air outlet port. The first compression mechanism and the second compression mechanism operate, the first compression mechanism compresses to form a first gas, the second compression mechanism compresses to form a second gas, and the first gas and the second gas are output through the first air outlet port to form a first output gas with a first pressure. In the second state, the first air inlet is connected to the air inlet port, the second air inlet is connected to the second air outlet port, the third air outlet port is connected to the second air outlet port, the first compression mechanism and the second compression mechanism operate, the first compression mechanism compresses to form a third gas, the second compression mechanism compresses the third gas to form a fourth gas, the fourth gas is output through the second air outlet port to form a second output gas with a second pressure, the second pressure being greater than the first pressure.

[0005] In this application, a gas is compressed by a compressor motor, enabling the air compressor to output both low-pressure first gas and high-pressure second gas. This integrates high and low-pressure air compressors, achieving the integration of high-pressure and low-pressure gas supply needs. In scenarios with both high and low-pressure requirements, only one air compressor is needed to meet both high-pressure and low-pressure gas supply needs. This facilitates a compact air compressor system structure and reduces the complexity and cost of the air compressor system.

[0006] In this application, by isolating and connecting the first and second compression mechanisms, parallel or series operation of the first and second compression mechanisms can be achieved, thereby realizing the output of high-pressure gas and low-pressure gas respectively. The structure is simple and conducive to miniaturization design. The series / parallel operation state of the first and second compression mechanisms can be switched by controlling the opening and closing of the second outlet and the second inlet, which is simple to implement.

[0007] In some possible implementations, the first compression mechanism and the second compression mechanism belong to the same compression motor.

[0008] In this implementation, since the first and second compression mechanisms belong to the same compression motor, they operate simultaneously in both the first and second states. In the first state, because the second compression mechanism can also independently compress gas to form low-pressure gas, it is not allowed to idle, thus avoiding energy loss caused by idling and improving the energy utilization rate of the air compressor.

[0009] In some possible implementations, the compressed air pump also includes a first check valve connected between the second outlet and the second inlet, which is used to control the opening and closing of the second outlet and the second inlet.

[0010] In this implementation, the first one-way valve controls the connection and disconnection between the second air outlet and the second air inlet, thereby enabling the switching between series / parallel operation of the first and second compression mechanisms. This allows for the switching between the first and second states of the compressed air pump without requiring additional air passage structures, simplifying the overall structure of the compressed air pump. This facilitates both high / low pressure air supply while simultaneously simplifying the pump's structure and miniaturizing its size. Furthermore, since the first one-way valve is a one-way valve, it prevents gas from flowing back into the first compression mechanism from the second compression mechanism.

[0011] In some possible implementations, the compressed air pump further includes a first control valve. The first control valve has a first inlet, a first outlet, and a second outlet. The first inlet can communicate with the first outlet, and the first inlet can also communicate with the second outlet. The first inlet is connected to an air intake port, the first outlet is connected to a first air inlet hole, and the second outlet is connected to a third air inlet hole. The first control valve is used to control the connection between the air intake port and the first air inlet hole, and also to control the connection between the air intake port and the third air inlet hole.

[0012] In this implementation, the first control valve controls the connection between the air inlet and the second compression mechanism based on their series / parallel operation. When the first and second compression mechanisms operate in parallel, the first control valve connects the air path between the air inlet and the second compression mechanism, allowing external atmosphere to enter the second compression mechanism for primary compression to form low-pressure gas. When the first and second compression mechanisms are connected in series, the first control valve disconnects the air path between the air inlet and the second compression mechanism to prevent external atmosphere from directly entering the second compression mechanism and affecting the formation of high-pressure gas.

[0013] In some possible implementations, the air inlet includes a first sub-inlet and a second sub-inlet spaced apart, with the first air inlet hole connected to the first sub-inlet and the third air inlet hole connected to the second sub-inlet.

[0014] In this implementation, by dividing the air inlet into a first sub-inlet and a second sub-inlet, the first compression mechanism and the second compression mechanism are connected to the outside with independent air paths, which is beneficial for the independent air intake control of the first compression mechanism and the second compression mechanism.

[0015] In some possible implementations, the compressed air pump further includes a third check valve connected between the first sub-inlet and the first air inlet, the third check valve being used to control the on / off state between the first sub-inlet and the first air inlet. And / or, the compressed air pump further includes a fourth check valve connected between the second sub-inlet and the third air inlet, the fourth check valve being used to control the on / off state between the second sub-inlet and the third air inlet.

[0016] In this implementation, the third and fourth check valves control the connection between the second sub-inlet and the second compression mechanism based on their series / parallel operation. When the first and second compression mechanisms operate in parallel, the fourth check valve connects the gas path between the second sub-inlet and the second compression mechanism, allowing external atmosphere to enter the second compression mechanism for primary compression to form low-pressure gas. When the first and second compression mechanisms are connected in series, the fourth check valve isolates the gas path between the second sub-inlet and the second compression mechanism to prevent external atmosphere from entering the second compression mechanism and affecting the formation of high-pressure gas.

[0017] In some possible implementations, the compressed air pump further includes a second control valve. The second control valve has a second inlet, a third inlet, and a third outlet. The second inlet and the third outlet are connected. The second inlet is connected to a first air outlet, the third inlet is connected to a fourth air outlet, and the third outlet is connected to a second air outlet. The second control valve is used to control the connection between the first air outlet and the first air outlet, and also to control the connection between the fourth air outlet and the first air outlet.

[0018] In this implementation, the second control valve controls the connection / disconnection between the first outlet and the first and second compression mechanisms based on their series / parallel operation. When the first and second compression mechanisms operate in parallel, the second control valve connects the first outlet to the gas path between them, allowing the low-pressure gases formed by the first and second compression mechanisms through primary compression to converge and be output from the first outlet. When the first and second compression mechanisms are connected in series, the second control valve disconnects the gas path between the first outlet and the second compression mechanisms to prevent leakage of gas compressed by the first compression mechanism from affecting the high-pressure gas formed by the second compression mechanism, and also to prevent leakage of high-pressure gas formed by the second compression mechanism from the first outlet, which could damage the device connected to the first outlet.

[0019] In some possible implementations, the first air outlet includes a first sub-outlet and a second sub-outlet spaced apart, the first air outlet can be connected to the first sub-outlet, and the fourth air outlet can be connected to the second sub-outlet.

[0020] In this implementation, by dividing the first air outlet into a first sub-outlet and a second sub-outlet, the first compression mechanism and the second compression mechanism are connected to an external low-pressure air supply device with independent air paths, which is beneficial for the independent air intake control of the first compression mechanism and the second compression mechanism.

[0021] In some possible implementations, the compressed air pump further includes a fifth check valve connected between the first outlet and the first sub-outlet, which controls the on / off connection between the first outlet and the first sub-outlet. And / or, the compressed air pump further includes a sixth check valve connected between the fourth outlet and the second sub-outlet, which controls the on / off connection between the fourth outlet and the second sub-outlet.

[0022] In this implementation, the fifth and sixth check valves control the airflow between the first sub-outlet and the first compression mechanism, and between the second sub-outlet and the second compression mechanism, based on the series / parallel operation of the first and second compression mechanisms. When the first and second compression mechanisms operate in parallel, the fifth check valve connects the airflow between the first sub-outlet and the first compression mechanism, and the sixth check valve connects the airflow between the second sub-outlet and the second compression mechanism. The low-pressure gas generated by the first stage of compression in the first compression mechanism and the low-pressure gas generated by the first stage of compression in the second compression mechanism can be output through the first and second sub-outlets, respectively. When the first and second compression mechanisms are connected in series, the fifth check valve isolates the airflow between the first sub-outlet and the first compression mechanism to prevent the low-pressure gas generated by the first stage of compression in the first compression mechanism from leaking out through the first sub-outlet, and the sixth check valve isolates the airflow between the second sub-outlet and the second compression mechanism to prevent the high-pressure gas generated by the second stage of compression in the second compression mechanism from leaking out through the second sub-outlet.

[0023] In some possible implementations, the compressed air pump also includes a sensor for detecting the air pressure in the air path of the compressed air pump, or for detecting the temperature of the first compression mechanism and / or the second compression mechanism.

[0024] In this implementation, the use of sensors assists in the operation of the compressed air pump. When the sensor detects the air pressure in the compressed air pump's air path, it can check whether the compressed air pressure meets expectations, allowing for adjustments to the compression power and enabling closed-loop control, thus improving the accuracy of the output air pressure. When the sensor detects the temperature of the first and / or second compression mechanisms, it allows for monitoring of the compressed air pump's operating temperature, preventing damage from excessively high operating temperatures caused by prolonged operation.

[0025] In some possible implementations, the maximum value of the first air pressure is in the range of 6 Bar to 8 Bar, so that the compressed air pump can supply low-pressure gas to the first air-consuming device. For example, the first air-consuming device can be a seat, side wing, central oxygen-generating decoration, radar cleaning device, air supply device, etc., and the compressed air pump can enable the function of the first air-consuming device by outputting a first output gas.

[0026] In some possible implementations, the second air pressure is greater than or equal to 10 Bar, enabling the compressed air pump to supply high-pressure gas to the second air-using device. For example, the second air-using device can be an air suspension with a closed air spring, and the compressed air pump can enable the function of the second air-using device by outputting a second output gas.

[0027] In some possible implementations, the second air pressure is greater than or equal to 18 Bar, enabling the compressed air pump to supply high-pressure gas to the second air-using device. For example, the second air-using device can be an air suspension with an open air spring, and the compressed air pump can enable the function of the second air-using device by outputting a second output gas.

[0028] Secondly, this application discloses a gas compression method. The compressed air pump includes a housing, a first compression mechanism, and a second compression mechanism. The housing has an inlet, a first outlet, and a second outlet spaced apart. The first compression mechanism has a first inlet, a first outlet, and a second outlet spaced apart. The second compression mechanism has a second inlet, a third inlet, a third outlet, and a fourth outlet spaced apart. The method includes:

[0029] Separate the second air outlet from the second air inlet, and separate the second air outlet from the third air outlet;

[0030] Connect the air inlet to the first air inlet and the third air inlet, and connect the first air outlet to the first air outlet and the fourth air outlet;

[0031] When the first and second compression mechanisms are in operation, the first outlet outputs gas with a first pressure.

[0032] In this application, since the first compression mechanism and the second compression mechanism work simultaneously, in the first state, the second compression mechanism can also compress the gas independently to form a low-pressure gas. Therefore, in the first state, the second compression mechanism is not allowed to idle, which avoids the energy loss caused by the idling of the compression mechanism and improves the energy utilization rate of the compressed air pump.

[0033] In some possible implementations, the air inlet includes a first sub-inlet and a second sub-inlet spaced apart;

[0034] Connecting the air inlet to the first air inlet and the first air outlet, including:

[0035] Connect the first sub-inlet to the first air intake port, and connect the second sub-inlet to the third air intake port.

[0036] In this implementation, by dividing the air inlet into a first sub-inlet and a second sub-inlet, the first compression mechanism and the second compression mechanism are connected to the outside with independent air paths, which is beneficial for the independent air intake control of the first compression mechanism and the second compression mechanism.

[0037] In some possible implementations, the first air outlet includes a first sub-outlet and a second sub-outlet spaced apart.

[0038] Connecting the first air outlet, the first air vent, and the fourth air vent, including:

[0039] Connect the first sub-air outlet to the first air outlet, and connect the second sub-air outlet to the fourth air outlet.

[0040] In this implementation, by dividing the first air outlet into a first sub-outlet and a second sub-outlet, the first compression mechanism and the second compression mechanism are connected to an external low-pressure air supply device with independent air paths, which is beneficial for the independent air intake control of the first compression mechanism and the second compression mechanism.

[0041] In some possible implementations, after the first outlet outputs gas at a first pressure, or before isolating the second outlet from the second inlet and the second outlet from the third outlet, the method further includes:

[0042] The air inlet is isolated from the third air inlet, and the first air outlet is isolated from the first air outlet and the fourth air outlet.

[0043] Connect the air inlet to the first air inlet, connect the second air outlet to the second air inlet, and connect the third air outlet to the second air outlet;

[0044] When the first and second compression mechanisms are in operation, the second outlet outputs gas with a second pressure, wherein the second pressure is greater than the first pressure.

[0045] In this implementation, the gas is compressed by a compressor motor, enabling the air compressor to output both low-pressure first gas and high-pressure second gas. This integrates high and low-pressure air compressors, achieving the integration of high-pressure and low-pressure gas supply needs. For scenarios with both high and low-pressure requirements, only one air compressor is needed to meet both high-pressure and low-pressure gas supply needs. This facilitates a compact air compressor system structure and reduces the complexity and cost of the air compressor system.

[0046] In this implementation, by isolating and connecting the first and second compression mechanisms, parallel or series operation of the first and second compression mechanisms can be achieved, thereby realizing the output of high-pressure gas and low-pressure gas respectively. The structure is simple and conducive to miniaturization design. The series / parallel operation state of the first and second compression mechanisms can be switched by controlling the opening and closing of the second outlet and the second inlet, which is also simple to implement.

[0047] Thirdly, this application provides a control device. The control device includes: at least one processor coupled to at least one memory, for executing computer instructions stored in the memory to cause the control device to perform any of the methods described in the second aspect.

[0048] Fourthly, this application provides a chip or chip system. The chip or chip system includes: at least one processing circuit, at least one processor circuit for running a computer program, causing the chip or chip system to perform any of the methods described in the second aspect.

[0049] Fifthly, this application provides a computer-readable storage medium. The computer-readable storage medium stores a computer program or instructions that, when executed on a computer, cause the computer to perform any of the methods described in the second aspect.

[0050] Sixthly, this application provides a computer program product. When the computer program product is run on a computer, it causes the computer to perform any of the methods described in the second aspect.

[0051] In a seventh aspect, this application provides an air pump system. The air pump system includes a first air-using device, a second air-using device, and a compressed air pump as described in any of the first aspects, wherein the first air-using device is connected to a first air outlet, and the second air-using device is connected to a second air outlet.

[0052] In this application, a compressed air pump can output two gases at different pressures to supply gas to a first gas-consuming device and a second gas-consuming device respectively, thereby achieving the supply of multiple gas pressures. This allows a single air pump system to be adapted to various application scenarios, enriching the application scenarios of air pump systems. Furthermore, for the first and second gas-consuming devices with different gas pressure requirements, a single compressed air pump can provide separate gas supplies, achieving integration of the compressed air pump to meet different gas supply needs. This results in a compact compressed air pump structure, reduced system complexity and cost, and improved space utilization in the cabin or vehicle.

[0053] Eighthly, this application provides a cockpit. The cockpit includes an air pump system as described in the seventh aspect.

[0054] In this application, since the air pump system can supply air to the first and second air-using devices with different air pressure requirements through a single compressed air pump, the compressed air pump is integrated to meet different air supply requirements, making the compressed air pump structure compact, reducing system complexity and cost, and improving the space utilization of the cabin.

[0055] Ninthly, this application provides a means of transportation. The means of transportation includes an air pump system as described in the seventh aspect, or includes a cabin as described in the seventh aspect.

[0056] In this application, since the air pump system can supply air to the first and second air-using devices with different air pressure requirements through a single compressed air pump, the compressed air pump is integrated to meet different air supply requirements, making the compressed air pump structure compact, reducing system complexity and cost, and improving the space utilization of the vehicle.

Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0080] The following section presents an application example of the compressed air pump 1 in the vehicle 1000 and the cabin 100.

[0081] Please refer to the following: Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the vehicle 1000 provided in some embodiments of this application; Figure 2 This is a schematic block diagram of the air pump system 10 provided in some embodiments of this application.

[0082] In some embodiments, the vehicle 1000 can be a vehicle, rail vehicle, ship, aircraft, etc. The vehicle can be, but is not limited to, a sedan, multi-purpose vehicle (MPV), sport / suburban utility vehicle (SUV), off-road vehicle (ORV), pickup truck, van, bus, truck, etc. Figure 1 In this embodiment, the vehicle 1000 is described as an example. Of course, other types of vehicles 1000 can also adopt a similar structure, which will not be described in detail below.

[0083] It should be noted that, Figure 1 The diagram only illustrates a portion of the structure of the vehicle 1000. In other embodiments, the vehicle 1000 may include more or fewer structures, which is not limited here.

[0084] Please see Figure 1In some embodiments, the vehicle 1000 may include a cabin 100. For example, when the vehicle 1000 is a vehicle, the cabin 100 may be the front cabin or the rear cabin of the vehicle.

[0085] For example, the vehicle 1000 may also include an air pump system 10, which may be installed inside the cabin 100 and be part of the cabin 100, or the air pump system 10 may be outside the cabin 100.

[0086] For example, the air pump system 10 can achieve air suspension adjustment, seat massage, active side wing adjustment, automatic tire inflation, central oxygen generation, radar cleaning, and external air supply by outputting gas.

[0087] Please see Figure 2 In some embodiments, the air pump system 10 may include a compressed air pump 1, a first air-consuming device 2, and a second air-consuming device 3. The compressed air pump 1 may have an inlet 111, a first outlet 112, and a second outlet 113 spaced apart. The inlet 111 is for connecting to the atmosphere, the first air-consuming device 2 is connected to the first outlet 112, and the second air-consuming device 3 is connected to the second outlet 113. The compressed air pump 1 is used to output a first output gas to the first air-consuming device 2 through the first outlet 112, and to output a second output gas to the second air-consuming device 3 through the second outlet 113. The first output gas has a first pressure, and the second output gas has a second pressure, the first pressure being different from the second pressure.

[0088] In this embodiment, the compressed air pump 1 can output two different gas pressures to supply gas to the first gas-consuming device 2 and the second gas-consuming device 3 respectively, thereby achieving the supply of multiple gas pressures. This allows a single air pump system 10 to be adapted to various application scenarios, enriching its application scope. Furthermore, the compressed air pump 1 can supply gas to the first gas-consuming device 2 and the second gas-consuming device 3 with different gas pressure requirements, achieving integration of the compressed air pump 1 to meet different gas supply needs. This makes the compressed air pump 1 more compact, reducing system complexity and cost, and improving the space utilization of the cabin 100 or vehicle 1000.

[0089] For example, the second pressure can be greater than the first pressure, the second pressure is high pressure, and the first pressure is low pressure.

[0090] In this embodiment, the compressed air pump 1 can integrate high-pressure air supply and low-pressure air supply, so that the compressed air pump 1 can be adapted to both high-pressure air supply scenarios and low-pressure air supply scenarios, effectively reducing the complexity and cost of the system.

[0091] For example, the second air-using device 3 can be an air suspension, a tire inflation device, etc., and the compressed air pump 1 can enable the function of the second air-using device 3 by outputting a second output gas.

[0092] The maximum value of the first air pressure can be in the range of 6 Bar to 8 Bar, so that the compressed air pump 1 can supply low-pressure gas to the first air-using device 2.

[0093] For example, the first air-using device 2 can be a seat, side wing, central oxygen-generating decoration, radar cleaning device, air supply device, etc., and the compressed air pump 1 can enable the function of the first air-using device 2 by outputting the first output gas.

[0094] It should be noted that the above-mentioned air pressure range refers to the maximum range of the first air pressure, and does not limit the first air pressure to between 6 Bar and 8 Bar. Understandably, the first air pressure can also be less than 6 Bar. For example, when the first air-using device 2 is a seat, if the compressed air pump 1 supplies air at the maximum value of the first air pressure, the seat will achieve the most intense massage level; if the compressed air pump 1 supplies air at a first air pressure less than 6 Bar, the seat will achieve a less intense massage level.

[0095] The value of the second air pressure can be greater than or equal to 10 Bar, so that the compressed air pump 1 can supply high-pressure gas to the second air-using device 3.

[0096] For example, the second air-using device 3 can be an air suspension, and the air spring in the air suspension is a closed air spring. The compressed air pump 1 can enable the function of the second air-using device 3 by outputting a second output gas.

[0097] The value of the second air pressure can be greater than or equal to 18 Bar, so that the compressed air pump 1 can supply high-pressure gas to the second air-using device 3.

[0098] For example, the second air-using device 3 can be an air suspension, and the air spring in the air suspension is an open air spring. The compressed air pump 1 can enable the function of the second air-using device 3 by outputting a second output gas.

[0099] In other embodiments, the compressed air pump 1 can also be applied to fields such as aerospace, industrial automation, and medical equipment.

[0100] For example, in the aerospace field, compressed air pump 1 can be used to regulate the air pressure inside an aircraft cabin; in industrial automation, compressed air pump 1 can be used for the pneumatic control of precision machinery; in medical equipment, compressed air pump 1 can be used to regulate the air pressure in operating rooms or wards.

[0101] The specific structure and air circuit design of the compressed air pump 1 in this application will be described in detail below.

[0102] Please refer to the following: Figures 3 to 5 , Figure 3 yes Figure 2 A schematic diagram of the compressed air pump 1 in some embodiments of the air pump system 10 shown; Figure 4 yes Figure 3 The diagram shown illustrates the output of low-pressure gas by the compressed air pump 1 in some embodiments. Figure 5 yes Figure 3 The diagram shown is a schematic of the compressed air pump 1 outputting high-pressure gas in some embodiments.

[0103] Please see Figure 3 In some embodiments, the compressed air pump 1 may include a housing 11 and a compressor motor 12. The housing 11 may have an air inlet 111, a first air outlet 112, and a second air outlet 113 spaced apart. The compressor motor 12 is installed inside the housing 11 and is connected to the air inlet 111, the first air outlet 112, and the second air outlet 113, respectively. The air inlet 111 is used to connect to the atmosphere, and the compressor motor 12 is used to compress gas and output a first output gas with a first air pressure through the first air outlet 112, and also to compress gas and output a second output gas with a second air pressure through the second air outlet 113.

[0104] In this embodiment, the gas is compressed by the compression motor 12, so that the compression pump 1 can output both low-pressure first output gas and high-pressure second output gas. This integrates the high and low pressure pumps and the high and low pressure gas supply requirements. In scenarios with both high and low pressure requirements, only one compression pump 1 is needed to meet both high and low pressure gas supply requirements. This is beneficial for achieving a compact structure of the air pump system 10 and reducing the complexity and cost of the air pump system 10.

[0105] For example, the compressor motor 12 may include a first compression mechanism 121 and a second compression mechanism 122; in other words, the first compression mechanism 121 and the second compression mechanism 122 belong to the same compressor motor 12. The air compressor 1 has a first state and a second state. In the first state, the air compressor 1 is used to output a low-pressure first output gas; in the second state, the air compressor 1 is used to output a high-pressure second output gas.

[0106] Specifically, please refer to Figure 4In the first state, the air inlet 111 is connected to the first compression mechanism 121 and the second compression mechanism 122 respectively, and the first air outlet 112 is connected to the first compression mechanism 121 and the second compression mechanism 122 respectively. The first compression mechanism 121 and the second compression mechanism 122 are separated. The first compression mechanism 121 and the second compression mechanism 122 work in parallel. The first compression mechanism 121 compresses to form a first gas, and the second compression mechanism 122 compresses to form a second gas. The first gas and the second gas are output together through the first air outlet 112 to form the first output gas.

[0107] It should be noted that, Figure 4 The dashed line with an arrow in the middle indicates the gas flow path.

[0108] Please see Figure 5 In the second state, the air inlet 111, the first compression mechanism 121, the second compression mechanism 122 and the second air outlet 113 are connected in sequence. The first compression mechanism 121 and the second compression mechanism 122 work in series. The first compression mechanism 121 compresses to form a third gas, and the second compression mechanism 122 compresses the third gas to form a fourth gas. The fourth gas is output through the second air outlet 113 to form the second output gas.

[0109] It should be noted that, Figure 5 The dashed line with an arrow in the middle indicates the gas flow path.

[0110] In this embodiment, by separating and connecting the first compression mechanism 121 and the second compression mechanism 122, the first compression mechanism 121 and the second compression mechanism 122 can be connected in parallel or in series, thereby realizing the output of high-pressure gas and low-pressure gas respectively. The structure is simple and conducive to miniaturization design.

[0111] In this embodiment, since the first compression mechanism 121 and the second compression mechanism 122 belong to the same compression motor 12, both the first compression mechanism 121 and the second compression mechanism 122 operate simultaneously in both the first and second states. In the first state, since the second compression mechanism 122 can also independently compress gas to form low-pressure gas, it is not allowed to idle, thus avoiding energy loss caused by idling and improving the energy utilization rate of the air compressor 1.

[0112] The compressor motor 12 can be a multi-stage compressor, with the first stage being a first compression mechanism 121 and the second stage being a second compression mechanism 122. The first compression mechanism 121 and the second compression mechanism 122 can use the same compression principle to compress air, or they can use different compression principles. For example, the first compression mechanism 121 can be a rotor compression structure or an eddy current compression structure, and the second compression mechanism 122 can be a rotor compression structure or an eddy current compression structure, etc.

[0113] Please see Figure 3 The first compression mechanism 121 may have a first air inlet 1211, a first air outlet 1212, and a second air outlet 1213 spaced apart. The first air inlet 1211 is connected to the air inlet 111, and the first air outlet 1212 is connected to the first air outlet 112. The second compression mechanism 122 may have a second air inlet 1221, a third air inlet 1222, a third air outlet 1223, and a fourth air outlet 1224 spaced apart. The second air inlet 1221 is connected to the second air outlet 1213, the third air inlet 1222 is connected to the air inlet 111, the third air outlet 1223 is connected to the second air outlet 113, and the fourth air outlet 1224 is connected to the first air outlet 112.

[0114] Please see Figure 4 In the first state, the first air inlet 1211 is connected to the air inlet 111, the first air outlet 1212 is connected to the first air outlet 112, the third air inlet 1222 is connected to the air inlet 111, and the fourth air outlet 1224 is connected to the first air outlet 112. The first compression mechanism 121 and the second compression mechanism 122 work together. The first compression mechanism 121 compresses to form a first gas, and the second compression mechanism 122 compresses to form a second gas. The first gas and the second gas are output together through the first air outlet 112 to form the first output gas.

[0115] Please see Figure 5 In the second state, the first air inlet 1211 is connected to the air inlet 111, the second air inlet 1221 is connected to the second air outlet 1213, and the third air outlet 1223 is connected to the second air outlet 113. The first compression mechanism 121 and the second compression mechanism 122 work together. The first compression mechanism 121 compresses the gas to form a third gas, and the second compression mechanism 122 compresses the third gas to form a fourth gas. The fourth gas is output through the second air outlet 113 to form the second output gas.

[0116] In this embodiment, the series / parallel operation of the first compression mechanism 121 and the second compression mechanism 122 can be switched by controlling the on / off state between the second air outlet 1213 and the second air inlet 1221, which is a simple implementation method.

[0117] It should be noted that the connection between the above-mentioned vents or air ports can be achieved by using a pipe design, or by excavating a channel inside the shell 11. In other words, the thickness of the shell 11 can be thicker than shown in the figure. By excavating a channel inside the shell 11 to form an air passage, the connection between the vents or air ports can be achieved.

[0118] It should be noted that the pressure values ​​of the first gas, the second gas, and the third gas can be the same or different, and this is not limited here. That is, the compression ratios of the first compression mechanism 121 and the second compression mechanism 122 can be the same.

[0119] Please continue reading. Figure 3 In some embodiments, the compressed air pump 1 may further include a first one-way valve 13, which is connected between the second air outlet 1213 and the second air inlet 1221. The first one-way valve 13 is used to control the opening and closing of the second air outlet 1213 and the second air inlet 1221.

[0120] In this embodiment, the first one-way valve 13 controls the opening and closing of the second air outlet 1213 and the second air inlet 1221, thereby realizing the series / parallel operation switch between the first compression mechanism 121 and the second compression mechanism 122. This allows for the switching between the first and second states of the compressed air pump 1 without the need for additional air passage structures, simplifying the overall structure of the compressed air pump 1. This facilitates both high / low pressure air supply while achieving structural simplification and miniaturization of the compressed air pump 1. Furthermore, since the first one-way valve 13 is a one-way valve, it prevents gas in the second compression mechanism 122 from flowing back into the first compression mechanism 121.

[0121] For example, the first check valve 13 can be a solenoid valve, so that the first check valve 13 can be electrically connected to the control system, and the control system can realize the switching control of the first check valve 13, which is conducive to realizing intelligent control.

[0122] The control system can be integrated into the compressed air pump 1, or installed in the aforementioned air pump system 10, cabin 100, or vehicle 1000.

[0123] In some embodiments, the compressed air pump 1 further includes a first control valve 14, which has a first inlet 141, a first outlet 142, and a second outlet 143. The first inlet 141 is connected to the first outlet 142, and the first inlet 141 is also connected to the second outlet 143. The first inlet 141 is connected to an air inlet 111, the first outlet 142 is connected to a first air inlet port 1211, and the second outlet 143 is connected to a third air inlet port 1222. The first control valve 14 is used to control the connection and disconnection between the air inlet 111 and the first air inlet port 1211, and also to control the connection and disconnection between the air inlet 111 and the third air inlet port 1222.

[0124] In this embodiment, the first control valve 14 can control the connection between the air inlet 111 and the second compression mechanism 122 according to the series / parallel operation state between the first compression mechanism 121 and the second compression mechanism 122. When the first compression mechanism 121 and the second compression mechanism 122 are operating in parallel, the first control valve 14 can connect the air passage between the air inlet 111 and the second compression mechanism 122, so that external atmosphere can enter the second compression mechanism 122 to achieve primary compression and form low-pressure gas. When the first compression mechanism 121 and the second compression mechanism 122 are connected in series, the first control valve 14 can disconnect the air passage between the air inlet 111 and the second compression mechanism 122 to prevent external atmosphere from directly entering the second compression mechanism 122 and affecting the formation of high-pressure gas.

[0125] For example, the first control valve 14 can be a solenoid valve, that is, a two-position three-way solenoid valve with one inlet and two outlets, so that the first control valve 14 can be electrically connected to the control system. The control system can realize the linkage control of the first control valve 14 and the first check valve 13, thereby improving the efficiency of the compressed air pump 1 in outputting high / low air pressure and the efficiency of switching working states.

[0126] In some embodiments, the compressed air pump 1 may further include a second control valve 15, which has a second inlet 151, a third inlet 152, and a third outlet 153. The second inlet 151 is connected to the third outlet 153, and the third inlet 152 is connected to the third outlet 153. The second inlet 151 is connected to a first air outlet 1212, the third inlet 152 is connected to a fourth air outlet 1224, and the third outlet 153 is connected to a second air outlet 113. The second control valve 15 is used to control the connection and disconnection between the first air outlet 1212 and the first air outlet 112, and the second control valve 15 is also used to control the connection and disconnection between the fourth air outlet 1224 and the first air outlet 112.

[0127] In this embodiment, the second control valve 15 can control the connection and disconnection between the first outlet 112 and the first compression mechanism 121 and the second compression mechanism 122 according to the series / parallel operation state between the first compression mechanism 121 and the second compression mechanism 122. When the first compression mechanism 121 and the second compression mechanism 122 are operating in parallel, the second control valve 15 can connect the air passage between the first outlet 112 and the first compression mechanism 121 and the second compression mechanism 122, so that the low-pressure gas formed by the first compression mechanism 121 and the second compression mechanism 122 through primary compression can be combined and output from the first outlet 112. When the first compression mechanism 121 and the second compression mechanism 122 are connected in series, the second control valve 15 can isolate the air passage between the first outlet 112 and the first compression mechanism 121 and the second compression mechanism 122, so as to prevent the gas compressed by the first compression mechanism 121 from leaking out and affecting the high-pressure gas formed by the second compression mechanism 122, and also to prevent the high-pressure gas formed by the second compression mechanism 122 from leaking out from the first outlet 112 and damaging the device connected to the first outlet 112.

[0128] For example, the second control valve 15 can be a solenoid valve, that is, a two-position three-way solenoid valve with two inlets and one outlet, so that the second control valve 15 can be electrically connected to the control system. Through the control system, the linkage control of the first control valve 14, the second control valve 15 and the first check valve 13 can be realized, thereby improving the efficiency of the compressed air pump 1 in outputting high / low air pressure and the efficiency of switching working states.

[0129] In some embodiments, the compressed air pump 1 may further include a second one-way valve 16, which is connected between the third air outlet 1223 and the second air outlet 113. The second one-way valve 16 is used to control the on / off connection between the third air outlet 1223 and the second air outlet 113.

[0130] In this embodiment, the second one-way valve 16 is designed to control the connection / disconnection between the third outlet 1223 and the second outlet 113 according to the series / parallel operation of the first compression mechanism 121 and the second compression mechanism 122. When the first compression mechanism 121 and the second compression mechanism 122 operate in parallel, the second one-way valve 16 controls the disconnection between the third outlet 1223 and the second outlet 113 to prevent the low-pressure gas formed by the compression of the second compression mechanism 122 from leaking out through the second outlet 113. When the first compression mechanism 121 and the second compression mechanism 122 operate in series, the second one-way valve 16 controls the connection between the third outlet 1223 and the second outlet 113 so that the high-pressure gas formed by the compression of the second compression mechanism 122 can be output through the second outlet 113. In addition, the second one-way valve 16 is a one-way valve, which can realize the one-way connection between the third outlet 1223 and the second outlet 113, and can prevent external gas from entering the second control mechanism through the second outlet 113.

[0131] For example, the second check valve 16 can be a solenoid valve, so that the second control valve 15 can be electrically connected to the control system. The control system can realize the linkage control of the first control valve 14, the second control valve 15, the first check valve 13 and the second check valve 16, thereby improving the efficiency of the compressed air pump 1 in outputting high / low air pressure and the efficiency of switching working states.

[0132] Specifically, please refer to Figure 4 In the first state, the first compression mechanism 121 and the second compression mechanism 122 work in parallel. The first control valve 14 is fully open, so that the air inlet 111 is connected to the air path between the first compression mechanism 121 and the second compression mechanism 122 respectively. The second control valve 15 is fully open, so that the first air outlet 112 is connected to the air path between the first compression mechanism 121 and the second compression mechanism 122 respectively. The first one-way valve 13 is closed, so as to isolate the air path between the first compression mechanism 121 and the second compression mechanism 122. The second one-way valve 16 is closed, so as to isolate the air path between the second compression mechanism 122 and the second air outlet 113. Therefore, after the external atmosphere enters the compressed air pump 1 through the air inlet 111, it will be divided into two paths through the first control valve 14 and enter the first compression mechanism 121 and the second compression mechanism 122 respectively. The low-pressure gas formed by compression in the first compression mechanism 121 will not enter the second compression mechanism 122, so that the second compression mechanism 122 directly compresses the external atmosphere to form low-pressure gas. The low-pressure gas formed by compression in the first compression mechanism 121 and the second compression mechanism 122 will merge at the second control valve 15 and be output through the first air outlet 112.

[0133] Please see Figure 5 In the second state, the first compression mechanism 121 and the second compression mechanism 122 operate in series. The first control valve 14 is partially open, connecting the air inlet 111 with the first compression mechanism 121 and simultaneously isolating the air inlet 111 from the second compression mechanism 122. The second control valve 15 is fully closed, isolating the air inlet 112 from both the first compression mechanism 121 and the second compression mechanism 122. The first one-way valve 13 is open, connecting the air inlet 121 with the second compression mechanism 122, and the second one-way valve 16 is open, connecting the second compression mechanism 122 with the second outlet 113. Therefore, after external air enters the compressed air pump 1 through the air inlet 111, it first enters the first compression mechanism 121 for primary compression to form low-pressure gas, and then enters the second compression mechanism 122 for secondary compression to form high-pressure gas, which is then output through the second outlet 113.

[0134] Please see Figure 6 , Figure 6 yes Figure 2 The diagram shows the structure of the compressed air pump 1 in the air pump system 10 in some other embodiments. It should be noted that... Figure 6 The compressed air pump 1 shown may include Figure 3 At least some of the features of the compressed air pump 1 shown are described, and the same features will not be repeated here.

[0135] In some embodiments, the compressed air pump 1 further includes a sensor 17, which is used to detect the air pressure in the air path of the compressed air pump 1, or to detect the temperature of the first compression mechanism 121 and / or the second compression mechanism 122.

[0136] In this embodiment, the sensor 17 is used to assist the operation of the compressed air pump 1. When the sensor 17 is used to detect the air pressure in the air path of the compressed air pump 1, it can detect whether the compressed air pressure in the compressed air pump 1 meets the expectation, so as to adjust the compression power and realize closed-loop control, which helps to improve the accuracy of the output air pressure. When the sensor 17 is used to detect the temperature of the first compression mechanism 121 and / or the second compression mechanism 122, it can monitor the operating temperature of the compressed air pump 1, avoiding damage to the compressed air pump 1 due to excessively high operating temperature caused by prolonged operation.

[0137] For example, sensor 17 may include a first sensor 171, which may be installed in the air path of compressed air pump 1 to detect the air pressure value in the air path.

[0138] For example, sensor 17 may also include a second sensor 172, which may be mounted on the outer surface of the first compression mechanism 121 and / or the second compression mechanism 122 for detecting the temperature of the first compression mechanism 121 and / or the second compression mechanism 122.

[0139] It should be noted that, Figure 6 The location of sensor 17 is only for illustration. In some other embodiments, sensor 17 may be installed in other locations according to actual needs.

[0140] Please refer to the following: Figures 7 to 9 , Figure 7 yes Figure 2 A schematic diagram of the structure of the compressed air pump 1 in the air pump system 10 shown in some other embodiments; Figure 8 yes Figure 7 The diagram shown illustrates the output of low-pressure gas by the compressed air pump 1 in some embodiments. Figure 9 yes Figure 7 The diagram shown illustrates the output of high-pressure gas by the compressed air pump 1 in some embodiments. It should be noted that... Figure 7 The compressed air pump 1 shown may include Figure 3 and Figure 6At least some of the features of the compressed air pump 1 shown are described, and the same features will not be repeated here.

[0141] In some embodiments, the air inlet 111 may include a first sub-inlet 1111 and a second sub-inlet 1112 spaced apart, the first air inlet 1211 being able to communicate with the first sub-inlet 1111, and the third air inlet 1222 being able to communicate with the second sub-inlet 1112.

[0142] In this embodiment, by dividing the air inlet 111 into a first sub-inlet 1111 and a second sub-inlet 1112, the first compression mechanism 121 and the second compression mechanism 122 are connected to the outside with independent air passages, which is beneficial to the independent air intake control of the first compression mechanism 121 and the second compression mechanism 122.

[0143] For example, the compressed air pump 1 may further include a third check valve 18a and a fourth check valve 18b. The third check valve 18a is connected between the first sub-inlet 1111 and the first air inlet 1211, and is used to control the on / off state between the first sub-inlet 1111 and the first air inlet 1211. The fourth check valve 18b is connected between the second sub-inlet 1112 and the third air inlet 1222, and is used to control the on / off state between the second sub-inlet 1112 and the third air inlet 1222.

[0144] In this embodiment, the third one-way valve 18a and the fourth one-way valve 18b can control the connection between the second sub-inlet 1112 and the second compression mechanism 122 according to the series / parallel operation state between the first compression mechanism 121 and the second compression mechanism 122. When the first compression mechanism 121 and the second compression mechanism 122 are operating in parallel, the fourth one-way valve 18b can connect the air passage between the second sub-inlet 1112 and the second compression mechanism 122, so that external atmosphere can enter the second compression mechanism 122 to achieve primary compression and form low-pressure gas. When the first compression mechanism 121 and the second compression mechanism 122 are connected in series, the fourth one-way valve 18b can disconnect the air passage between the second sub-inlet 1112 and the second compression mechanism 122 to prevent external atmosphere from entering the second compression mechanism 122 and affecting the formation of high-pressure gas.

[0145] Among them, the third check valve 18a and the fourth check valve 18b can be solenoid valves, so that the third check valve 18a and the fourth check valve 18b can be electrically connected to the control system, so that the control system can realize the linkage control of the third check valve 18a and the fourth check valve 18b, thereby improving the efficiency of the compressed air pump 1 in outputting high / low air pressure and the efficiency of working state switching.

[0146] Specifically, please refer to Figure 8In the first state, the first compression mechanism 121 and the second compression mechanism 122 work in parallel. The third one-way valve 18a controls the air passage connection between the first sub-inlet 1111 and the first compression mechanism 121, and the fourth one-way valve 18b controls the air passage connection between the second sub-inlet 1112 and the second compression mechanism 122, so that both the first compression mechanism 121 and the second compression mechanism 122 can directly compress the external atmosphere to form low-pressure gas.

[0147] Please see Figure 9 In the second state, the first compression mechanism 121 and the second compression mechanism 122 operate in series. The third one-way valve 18a controls the air passage between the first sub-inlet 1111 and the first compression mechanism 121, and the fourth one-way valve 18b controls the air passage between the second sub-inlet 1112 and the second compression mechanism 122. Therefore, external atmosphere cannot directly enter the second compression mechanism 122 through the second sub-inlet 1112. It can only enter the first compression mechanism 121 through the first sub-inlet 1111 to form low-pressure gas, and then undergo secondary compression through the second compression mechanism 122 to form high-pressure gas.

[0148] Please refer to the following: Figures 10 to 12 , Figure 10 yes Figure 2 A schematic diagram of the structure of the compressed air pump 1 in the air pump system 10 shown in some other embodiments; Figure 11 yes Figure 10 The diagram shown illustrates the output of low-pressure gas by the compressed air pump 1 in some embodiments. Figure 12 yes Figure 10 The diagram shown illustrates the output of high-pressure gas by the compressed air pump 1 in some embodiments. It should be noted that... Figure 10 The compressed air pump 1 shown may include Figure 3 and Figure 6 At least some of the features of the compressed air pump 1 shown are described, and the same features will not be repeated here.

[0149] In some embodiments, the first air outlet 112 may include a first sub-outlet 1121 and a second sub-outlet 1122 that are spaced apart, the first air outlet 1212 being able to communicate with the first sub-outlet 1121, and the fourth air outlet 1224 being able to communicate with the second sub-outlet 1122.

[0150] In this embodiment, by dividing the first air outlet 112 into a first sub-outlet 1121 and a second sub-outlet 1122, the first compression mechanism 121 and the second compression mechanism 122 are connected to the external low-pressure air supply device with independent air paths, which is beneficial to the independent air intake control of the first compression mechanism 121 and the second compression mechanism 122.

[0151] For example, the compressed air pump 1 may further include a fifth check valve 19a and a sixth check valve 19b. The fifth check valve 19a is connected between the first air outlet 1212 and the first sub-outlet 1121, and is used to control the on / off state between the first air outlet 1212 and the first sub-outlet 1121. The sixth check valve 19b is connected between the fourth air outlet 1224 and the second sub-outlet 1122, and is used to control the on / off state between the fourth air outlet 1224 and the second sub-outlet 1122.

[0152] In this embodiment, the fifth one-way valve 19a and the sixth one-way valve 19b can control the air passage connection between the first sub-outlet 1121 and the first compression mechanism 121, and between the second sub-outlet 1122 and the second compression mechanism 122, according to the series / parallel operation state between the first compression mechanism 121 and the second compression mechanism 122. When the first compression mechanism 121 and the second compression mechanism 122 are operating in parallel, the fifth one-way valve 19a can connect the air passage between the first sub-outlet 1121 and the first compression mechanism 121, and the sixth one-way valve 19b can connect the air passage between the second sub-outlet 1122 and the second compression mechanism 122. The low-pressure gas formed by the first compression mechanism 121 and the low-pressure gas formed by the first compression mechanism 122 can be output through the first sub-outlet 1121 and the second sub-outlet 1122, respectively. When the first compression mechanism 121 and the second compression mechanism 122 are connected in series, the fifth check valve 19a can isolate the air passage between the first sub-outlet 1121 and the first compression mechanism 121 to prevent the low-pressure gas formed by the first compression mechanism 121 in the first stage of compression from leaking out through the first sub-outlet 1121. The sixth check valve 19b can isolate the air passage between the second sub-outlet 1122 and the second compression mechanism 122 to prevent the high-pressure gas formed by the second compression mechanism 122 in the second stage of compression from leaking out through the second sub-outlet 1122.

[0153] Among them, the fifth check valve 19a and the sixth check valve 19b can be solenoid valves, so that the fifth check valve 19a and the sixth check valve 19b can be electrically connected to the control system, so that the control system can realize the linkage control of the fifth check valve 19a and the sixth check valve 19b, thereby improving the efficiency of the compressed air pump 1 in outputting high / low air pressure and the efficiency of working state switching.

[0154] Specifically, please refer to Figure 11 In the first state, the first compression mechanism 121 and the second compression mechanism 122 work in parallel. The fifth one-way valve 19a controls the gas path connection between the first sub-outlet 1121 and the first compression mechanism 121, and the sixth one-way valve 19b controls the gas path connection between the second sub-outlet 1122 and the second compression mechanism 122, so that both the first compression mechanism 121 and the second compression mechanism 122 can directly output gas for primary compression to form low-pressure gas.

[0155] Please see Figure 12 In the second state, the first compression mechanism 121 and the second compression mechanism 122 operate in series. The fifth check valve 19a controls the gas path isolation between the first sub-outlet 1121 and the first compression mechanism 121, and the sixth check valve 19b controls the gas path isolation between the second sub-outlet 1122 and the second compression mechanism 122. Therefore, it is possible to prevent the low-pressure gas formed by the first compression mechanism 121 during the first stage of compression from leaking out through the first sub-outlet 1121, and it is also possible to prevent the high-pressure gas formed by the second compression mechanism 122 during the second stage of compression from leaking out through the second sub-outlet 1122.

[0156] Please refer to the following: Figures 13 to 15 , Figure 13 yes Figure 2 A schematic diagram of the structure of the compressed air pump 1 in the air pump system 10 shown in some other embodiments; Figure 14 yes Figure 13 The diagram shown illustrates the output of low-pressure gas by the compressed air pump 1 in some embodiments. Figure 15 yes Figure 13 The diagram shown illustrates the output of high-pressure gas by the compressed air pump 1 in some embodiments. It should be noted that... Figure 13 The compressed air pump 1 shown may include Figure 3 and Figure 6 At least some of the features of the compressed air pump 1 shown are described, and the same features will not be repeated here.

[0157] In some embodiments, the air inlet 111 may include a first sub-inlet 1111 and a second sub-inlet 1112 spaced apart, a first air inlet 1211 connected to the first sub-inlet 1111, and a third air inlet 1222 connected to the second sub-inlet 1112. A third one-way valve 18a is connected between the first sub-inlet 1111 and the first air inlet 1211, and is used to control the on / off state between the two. A fourth one-way valve 18b is connected between the second sub-inlet 1112 and the third air inlet 1222, and is used to control the on / off state between the two. The first air outlet 112 may include a first sub-outlet 1121 and a second sub-outlet 1122 spaced apart, a first air outlet 1212 connected to the first sub-outlet 1121, and a fourth air outlet 1224 connected to the second sub-outlet 1122. The fifth one-way valve 19a is connected between the first vent 1212 and the first sub-outlet 1121, and is used to control the opening and closing of the connection between the first vent 1212 and the first sub-outlet 1121. The sixth one-way valve 19b is connected between the fourth vent 1224 and the second sub-outlet 1122, and is used to control the opening and closing of the connection between the fourth vent 1224 and the second sub-outlet 1122.

[0158] In this embodiment, the third one-way valve 18a and the fourth one-way valve 18b can control the on / off connection between the second sub-inlet 1112 and the second compression mechanism 122 according to the series / parallel operation state between the first compression mechanism 121 and the second compression mechanism 122. The fifth one-way valve 19a and the sixth one-way valve 19b can control the air passage connection between the first sub-outlet 1121 and the first compression mechanism 121, and between the second sub-outlet 1122 and the second compression mechanism 122 according to the series / parallel operation state between the first compression mechanism 121 and the second compression mechanism 122. When the first compression mechanism 121 and the second compression mechanism 122 are operating in parallel, the third one-way valve 18a can connect the first sub-inlet 1112 and the second compression mechanism 122. The gas path between the compressors includes a fourth one-way valve 18b that connects the gas path between the second sub-inlet 1112 and the second compression mechanism 122, a fifth one-way valve 19a that connects the gas path between the first sub-outlet 1121 and the first compression mechanism 121, and a sixth one-way valve 19b that connects the gas path between the second sub-outlet 1122 and the second compression mechanism 122. This allows external air to enter the first compression mechanism 121 and the second compression mechanism 122 respectively to achieve primary compression and form low-pressure gas. The low-pressure gas formed by the primary compression of the first compression mechanism 121 and the low-pressure gas formed by the primary compression of the second compression mechanism 122 can be output through the first sub-outlet 1121 and the second sub-outlet 1122 respectively. When the first compression mechanism 121 and the second compression mechanism 122 are connected in series, the third one-way valve 18a can connect the air passage between the first sub-inlet 111 and the first compressor, the fourth one-way valve 18b can disconnect the air passage between the second sub-inlet 1112 and the second compression mechanism 122 to prevent external atmosphere from entering the second compression mechanism 122 and affecting the formation of high-pressure gas, the fifth one-way valve 19a can disconnect the air passage between the first sub-outlet 1121 and the first compression mechanism 121 to prevent the low-pressure gas formed by the first compression stage of the first compression mechanism 121 from leaking out through the first sub-outlet 1121, and the sixth one-way valve 19b can disconnect the air passage between the second sub-outlet 1122 and the second compression mechanism 122 to prevent the high-pressure gas formed by the second compression stage of the second compression mechanism 122 from leaking out through the second sub-outlet 1122.

[0159] Specifically, please refer to Figure 14In the first state, the first compression mechanism 121 and the second compression mechanism 122 operate in parallel. The third one-way valve 18a controls the air passage connection between the first sub-inlet 1111 and the first compression mechanism 121, and the fourth one-way valve 18b controls the air passage connection between the second sub-inlet 1112 and the second compression mechanism 122, so that both the first compression mechanism 121 and the second compression mechanism 122 can directly perform primary compression on the external atmosphere to form low-pressure gas. The fifth one-way valve 19a controls the air passage connection between the first sub-outlet 1121 and the first compression mechanism 121, and the sixth one-way valve 19b controls the air passage connection between the second sub-outlet 1122 and the second compression mechanism 122, so that both the first compression mechanism 121 and the second compression mechanism 122 can directly output primary compression to form low-pressure gas.

[0160] Please see Figure 15 In the second state, the first compression mechanism 121 and the second compression mechanism 122 operate in series. The third one-way valve 18a controls the air passage between the first sub-inlet 1111 and the first compression mechanism 121, and the fourth one-way valve 18b controls the air passage between the second sub-inlet 1112 and the second compression mechanism 122. Therefore, external atmosphere cannot directly enter the second compression mechanism 122 through the second sub-inlet 1112. It can only enter the first compression mechanism 121 through the first sub-inlet 1111 to form low-pressure gas, and then undergo secondary compression through the second compression mechanism 122 to form high-pressure gas. The fifth check valve 19a controls the gas path isolation between the first sub-outlet 1121 and the first compression mechanism 121, and the sixth check valve 19b controls the gas path isolation between the second sub-outlet 1122 and the second compression mechanism 122. Therefore, it can prevent the low-pressure gas formed by the first compression stage of the first compression mechanism 121 from leaking out through the first sub-outlet 1121, and it can also prevent the high-pressure gas formed by the second compression stage of the second compression mechanism 122 from leaking out through the second sub-outlet 1122.

[0161] The structure of the compressed air pump provided in this application in some embodiments has been described above. Next, a method for gas compression using the compressed air pump provided in the embodiments of this application will be introduced.

[0162] Please see Figure 16 , Figure 16 This is a schematic flowchart of some embodiments of the gas compression method provided in this application.

[0163] In some embodiments, the gas compression method may include the following steps.

[0164] Step S10: Isolate the second air outlet 1213 from the second air inlet 1221, and isolate the second air outlet 113 from the third air outlet 1223.

[0165] Please refer to the following: Figure 3By controlling the first one-way valve 13 to close, the second air outlet 1213 and the second air inlet 1221 are isolated, that is, the air path between the first compression mechanism 121 and the second compression mechanism 122 is isolated. By controlling the second one-way valve 16 to close, the second air outlet 113 and the third air outlet 1223 are isolated, that is, the air path between the second compression mechanism 122 and the second air outlet 113 is isolated.

[0166] Step S20: Connect the air inlet 111 to the first air inlet 1211 and the third air inlet 1222, and connect the first air outlet 112 to the first air outlet 1212 and the fourth air outlet 1224.

[0167] In some examples, please refer to [the relevant documentation]. Figure 3 By controlling the first control valve 14 to be fully open, the air inlet 111 is connected to the first air inlet 1211 and the third air inlet 1222 respectively, thus ensuring that the air passages between the air inlet 111 and the first compression mechanism 121 and the second compression mechanism 122 are all connected. By controlling the second control valve 15 to be fully open, the first air outlet 112 is connected to the first air outlet 1212 and the fourth air outlet 1224 respectively, thus ensuring that the air passages between the first air outlet 112 and the first compression mechanism 121 and the second compression mechanism 122 are all connected.

[0168] In other examples, please refer to [reference needed]. Figure 7 and Figure 13 The air inlet 111 includes a first sub-inlet 1111 and a second sub-inlet 1112 spaced apart. By controlling the third one-way valve 18a and the fourth one-way valve 18b to open, the first sub-inlet 1111 is connected to the first air inlet 1211, and the second sub-inlet 1112 is connected to the third air inlet 1222. That is, the air passage between the first sub-inlet 1111 and the first compression mechanism 121 is connected, and the air passage between the second sub-inlet 1112 and the second compression mechanism 122 is connected.

[0169] In yet another example, please refer to Figure 10 and Figure 13 The first air outlet 112 includes a first sub-outlet 1121 and a second sub-outlet 1122 spaced apart. By controlling the fifth one-way valve 19a and the sixth one-way valve 19b to open, the first sub-outlet 1121 is connected to the first air outlet 1212, and the second sub-outlet 1122 is connected to the fourth air outlet 1224. That is, the air passage between the first sub-outlet 1121 and the first compression mechanism 121 is connected, and the air passage between the second sub-outlet 1122 and the second compression mechanism 122 is connected.

[0170] In step S30, the first compression mechanism 121 and the second compression mechanism 122 operate, and the first outlet 112 outputs gas with a first pressure.

[0171] In some examples, please refer to [the relevant documentation]. Figure 4 and Figure 8 Since both the first compression mechanism 121 and the second compression mechanism 122 can be directly connected to the outside atmosphere, the first compression mechanism 121 and the second compression mechanism 122 can achieve primary compression to form low-pressure gas, which is then combined to the first outlet 112 for output.

[0172] In other examples, please refer to [reference needed]. Figure 11 and Figure 14 The low-pressure gas formed by the first compression mechanism 121 through primary compression is output through the first sub-outlet 1121, and the low-pressure gas formed by the second compression mechanism 122 through primary compression is output through the second sub-outlet 1122.

[0173] In this embodiment, since the first compression mechanism 121 and the second compression mechanism 122 work simultaneously, in the first state, the second compression mechanism 122 can also compress gas independently to form low-pressure gas. Therefore, in the first state, the second compression mechanism 122 is not allowed to idle, thus avoiding energy loss caused by the idling of the compression mechanism and improving the energy utilization rate of the compressed air pump 1.

[0174] Step S40: Isolate the air inlet 111 from the third air inlet 1222, and isolate the first air outlet 112 from the first air outlet 1212 and the fourth air outlet 1224.

[0175] In some examples, please refer to [the relevant documentation]. Figure 3 By controlling the separation between the first inlet 141 and the second outlet 143 in the first control valve 14, the air inlet 111 and the third air inlet 1222 are separated, that is, the air path between the air inlet 111 and the second compression mechanism 122 is disconnected. By controlling the second control valve 15 to be fully closed, the first outlet 112 is isolated from both the first outlet 1212 and the fourth outlet 1224, that is, the air path between the first outlet 112 and both the first compression mechanism 121 and the second compression mechanism 122 is disconnected.

[0176] In other examples, please refer to [reference needed]. Figure 7 and Figure 13 The air inlet 111 includes a first sub-inlet 1111 and a second sub-inlet 1112 spaced apart. By controlling the fourth one-way valve 18b to close, the second sub-inlet 1112 is isolated from the third air inlet 1222, that is, the air path between the second sub-inlet 1112 and the second compression mechanism 122 is isolated.

[0177] In yet another example, please refer to Figure 10 and Figure 13The first air outlet 112 includes a first sub-outlet 1121 and a second sub-outlet 1122 spaced apart. By controlling the fifth one-way valve 19a and the sixth one-way valve 19b to close, the first sub-outlet 1121 is isolated from the first air outlet 1212, and the second sub-outlet 1122 is isolated from the fourth air outlet 1224. That is, the air path between the first sub-outlet 1121 and the first compression mechanism 121 is isolated, and the air path between the second sub-outlet 1122 and the second compression mechanism 122 is isolated.

[0178] Step S50: Connect the air inlet 111 to the first air inlet 1211, connect the second air outlet 1213 to the second air inlet 1221, and connect the third air outlet 1223 to the second air outlet 113.

[0179] In some examples, please refer to [the relevant documentation]. Figure 3 By controlling the connection between the first inlet 141 and the first outlet 142 in the first control valve 14, the air inlet 111 is connected to the first air inlet 1211, thus achieving air passage connection between the air inlet 111 and the first compression mechanism 121. By controlling the opening of the first one-way valve 13, the second air outlet 1213 is connected to the second air inlet 1221, thus achieving air passage connection between the first compression mechanism 121 and the second compression mechanism 122. By controlling the opening of the second one-way valve 16, the third air outlet 1223 is connected to the second air outlet 113, thus achieving air passage connection between the second compression mechanism 122 and the second air outlet 113.

[0180] In other examples, please refer to [reference needed]. Figure 7 and Figure 13 By controlling the opening of the third one-way valve 18a, the first sub-inlet 1111 is connected to the first air inlet 1211, that is, the air passage between the first sub-inlet 1111 and the first compression mechanism 121 is connected.

[0181] In step S60, the first compression mechanism 121 and the second compression mechanism 122 operate, and the second outlet 113 outputs gas with a second pressure.

[0182] Please refer to the following: Figure 5 , Figure 9 , Figure 12 and Figure 15 The first compression mechanism 121 can perform primary compression of externally introduced gas to form low-pressure gas, and the second compression mechanism 122 can further perform secondary compression to form high-pressure gas, so that the high-pressure gas can be output through the second outlet 113.

[0183] In this embodiment, the gas is compressed by the compression motor 12, so that the compression pump 1 can output both low-pressure first output gas and high-pressure second output gas. This integrates the high and low pressure pumps and the high and low pressure gas supply requirements. In scenarios with both high and low pressure requirements, only one compression pump 1 is needed to meet both high and low pressure gas supply requirements. This is beneficial for achieving a compact structure of the air pump system 10 and reducing the complexity and cost of the air pump system 10.

[0184] It should be noted that steps S10 to S30 correspond to the first state of the compressed air pump 1, and steps S40 to S60 correspond to the second state of the compressed air pump 1. The gas compression method can include any one of steps S10 to S30 and steps S40 to S60, that is, compressing to form low-pressure gas or high-pressure gas. The gas compression method can also include steps S10 to S30 and steps S40 to S60 simultaneously, that is, it can realize the conversion between compressing to form low-pressure gas and high-pressure gas during the compression stroke. The order of steps S10 to S30 and steps S40 to S60 is not limited, that is, it can be converted from the first state to the second state, or vice versa.

[0185] In some examples, when transitioning between the first state and the second state, between steps S30 and S40 or between steps S60 and S10, the operation of the first compression mechanism 121 and the second compression mechanism 122 may be stopped to ensure a more stable transition between the first state and the second state.

[0186] In other examples, when transitioning between the first state and the second state, it is not necessary to stop the operation of the first compression mechanism 121 and the second compression mechanism 122 between steps S30 and S40 or between steps S60 and S10, so as to make the transition between the first state and the second state smoother.

[0187] The execution and storage entities of the above gas compression method will be introduced next.

[0188] Please see Figure 17 , Figure 17 This is a schematic block diagram of a control device 2000 provided in an embodiment of this application.

In one example, one or more processors can acquire control information. In another example, one or more processors can control the compressed air pump 1 to be in a target state based on the control information. Exemplarily, in a specific implementation, the control device 2000 can be a controller for the compressed air pump 1, or it can be a chip or processor 2003 disposed in the controller.

[0193] Please see Figure 18 , Figure 18 This is a schematic block diagram of a control device 2000 provided in another embodiment of this application.

In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a type of microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. These logical relationships are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field-programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor 2003 loading a configuration document to configure the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), tensor processing unit (TPU), deep learning processing unit (DPU), etc.
