Abstract
Description
Technical Field
[0001] This utility model relates to the field of air supply device technology, and in particular to an auxiliary air intake enhancement device and an air suspension air supply system. Background Technology
[0002] The integrated ECAS air suspension module is used to achieve automatic vehicle height adjustment. The system's compressor draws air from the atmosphere and charges the air tank. A solenoid valve switches the air path, delivering high-pressure gas to the air springs to adjust the suspension height. Existing integrated air suspension systems mostly use low-power compressors to reduce module size. The primary function of these compressors is to provide air to the suspension system; their function is singular. In the original air path topology, during normal system operation, gas only circulates between the air tank and the air springs, and gas is only released to the outside through the exhaust valve when the dryer drains water.
[0003] However, in actual use, there is a need for external inflation (such as camping mattresses, balls, emergency inflatable tools, etc.). If the exhaust gas from the above-mentioned backflush operation is used directly to inflate external equipment, there are some problems, such as insufficient air volume, low compressor flow rate, long output time; unstable pressure, high backflush gas pressure that cannot be precisely controlled, making it unsuitable for direct external use.

The nozzle structure has a flow channel that gradually narrows along the direction of the airflow channel, which is used to accelerate the flow of the working airflow and form a low-pressure zone at the outlet end of the nozzle structure.

[0012] Furthermore, the nozzle structure is provided with a conical flow channel that gradually narrows along the direction of the airflow channel, and the diameter of the nozzle structure at the end near the working airflow inlet is larger than the diameter at the end away from the working airflow inlet.
[0013] Furthermore, the nozzle structure is integrally formed or fixedly connected to the air intake.

[0028] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0030] Please refer to Figure 1 and Figure 2 This application discloses an auxiliary air intake enhancement device 01, including a flow structure 1 and a nozzle structure 5. The flow structure 1 is provided with a working airflow inlet 2, an auxiliary mixing airflow inlet 3, and an airflow outlet 4. An airflow channel is formed between the working airflow inlet 2 and the airflow outlet 4. The auxiliary mixing airflow inlet 3 connects the external atmosphere with the airflow channel. The nozzle structure 5 is disposed in the airflow channel and has a flow channel that gradually narrows along the direction of the airflow channel. This is used to accelerate the working airflow and form a low-pressure zone at the outlet end of the nozzle structure 5, so that the airflow of the external atmosphere enters the airflow channel through the auxiliary mixing airflow inlet 3 and mixes with the working airflow before being discharged from the airflow outlet 4.
[0031] It should be noted that the working airflow inlet 2 is generally supplied by a gas supply device such as compressor 02, while the auxiliary mixing inlet 3 connects to the gas in the external atmospheric environment. The airflow outlet 4 can be connected to an external device 05 to supply gas. It is worth noting that the auxiliary airflow enhancement device 01 in this invention, through the arrangement of the flow structure 1 and the nozzle structure 5, accelerates the working airflow in the flow channel within the nozzle structure 5 and forms a low-pressure zone at the outlet end. This allows the auxiliary mixing inlet 3 to draw in external airflow, mixing it with the working airflow within the airflow channel, and then discharging it through the airflow outlet 4. Through this structural design, even with a limited airflow from compressor 02, additional atmospheric air can be effectively drawn into the airflow channel, significantly increasing the total output airflow and thus solving the problem of insufficient air supply efficiency caused by the low power of existing compressor 02.
[0032] In some embodiments, please refer to Figure 1 and Figure 2The flow structure 1 includes an air inlet 6, an air guide 7, and an exhaust 8 connected sequentially along the airflow channel direction; the working airflow inlet 2 and the auxiliary mixing air inlet 3 are opened on the air inlet 6, and the airflow outlet 4 is opened on the exhaust 8; the inner diameter of the air guide 7 is smaller than the inner diameter of the air inlet 6 and the exhaust 8.
[0033] Specifically, the three structural parts—intake section 6, guide section 7, and exhaust section 8—are connected sequentially along the airflow channel. The working airflow inlet 2 and the auxiliary mixing inlet 3 are located in the intake section 6, facilitating the entry of the working airflow and the external atmospheric airflow into the system. The airflow outlet 4 is located in the exhaust section 8, ensuring smooth airflow output to the corresponding external device 05. The guide section 7 connects the intake section 6 and the exhaust section 8, serving as a transition and guide. This segmented structure can be detachably connected or integrally molded; different structures help improve airflow stability and increase processing and assembly flexibility. It should be noted that in the flow structure 1, the guide section 7, as a transitional connecting section between the intake section 6 and the exhaust section 8, has an inner diameter smaller than that of both the intake section 6 and the exhaust section 8. This reduced diameter design generates a certain convergence and acceleration effect when the airflow passes through the guide section 7, making the airflow more concentrated and stable before entering the exhaust section 8. The degree of inner diameter reduction in the guide section 7 can be matched according to the output flow rate and the characteristics of the nozzle structure 5 to avoid excessive resistance while ensuring a more pronounced negative pressure area. This structure not only helps to enhance the guiding effect of airflow during the flow process, but its converging effect can also effectively improve the mixing efficiency of external atmospheric airflow and working airflow, thereby further improving the overall air supply effect of the enhancement device.
[0034] In some embodiments, please refer to Figure 1 and Figure 2 The air intake 6 is provided with an air intake chamber. The working airflow inlet 2 and the auxiliary mixing air inlet 3 are both connected to the air intake chamber. The nozzle structure 5 is disposed in the air intake chamber. One end of the nozzle structure 5 is connected to the working airflow inlet 2, and the other end of the nozzle structure 5 faces the air guide 7.
[0035] Specifically, an air intake chamber is formed inside the air intake section 6, and both the working airflow inlet 2 and the auxiliary mixing airflow inlet 3 are connected to the air intake chamber. One end of the nozzle structure 5 is connected to the working airflow inlet 2, and the other end faces the airflow guide section 7 to achieve directional injection of airflow. This air intake chamber can adopt a cylindrical or square cavity structure to ensure airflow uniformity. By arranging the nozzle structure 5 inside the air intake chamber, it is easier to concentrate and guide the airflow, thereby enhancing mixing efficiency.
[0036] In some embodiments, please refer to Figure 1 and Figure 2The nozzle structure 5 has a conical flow channel that gradually narrows along the direction of the airflow channel. The diameter of the nozzle structure 5 at the end near the working airflow inlet 2 is larger than the diameter at the end away from the working airflow inlet 2.
[0037] Specifically, the nozzle structure 5 has a conical flow channel that gradually narrows along the airflow channel direction. The diameter of the channel is larger near the working airflow inlet 2 and smaller further away from the inlet. The nozzle structure 5 can gradually reduce the cross-sectional area of the flow channel within a limited space to achieve stable acceleration of the airflow under critical conditions, ensure the formation of a low-pressure zone at the outlet end, and improve the entrainment efficiency of the external airflow.
[0038] In some embodiments, the nozzle structure 5 and the air intake 6 are integrally formed or fixedly connected.
[0039] Specifically, the nozzle structure 5 can be integrally formed with the air intake 6 by injection molding, one-piece casting, or machining, or it can be fixedly connected by means of threads, welding, or snap-fit. Different connection methods are suitable for different manufacturing needs and cost requirements. One-piece molding can improve overall strength and durability, while fixed connection facilitates later replacement or maintenance.
[0040] In some embodiments, please refer to Figure 1 and Figure 2 The auxiliary mixing air inlet 3 is located in the circumferential position of the air inlet 6, and the axial direction of the auxiliary mixing air inlet 3 is perpendicular to the direction of the airflow channel.
[0041] Specifically, the auxiliary mixing air inlet 3 is located on the circumference of the air inlet 6, with its opening direction perpendicular to the airflow channel direction. This position facilitates the uniform entry of external air into the airflow channel, reducing airflow resistance. The air inlet can adopt a circular or multi-hole structure, and the specific shape can be selected according to requirements. Through circumferential arrangement and vertical setting, external airflow can be effectively introduced without affecting the mainstream direction of the working airflow, thereby improving mixing efficiency.
[0042] In some embodiments, please refer to Figure 1 and Figure 2 An air intake connection pipe 9 is provided on the outer side of the air intake part 6. The air intake connection pipe 9 is connected to the working airflow inlet 2, and a threaded interface is provided on the outside of the air intake connection pipe 9.
[0043] Specifically, the air inlet connecting pipe 9 connects to the working airflow inlet 2, serving as the connection channel between the external compressor 02 providing the working airflow and this device. The threaded interface can be internal or external threaded, or a quick-connect fitting can be used. Different interface designs can be adapted to different air pipes or fittings, facilitating installation and replacement. This structure improves the compatibility of the device with working airflow supply equipment, expanding its application range.
[0044] In some embodiments, please refer to Figure 1 and Figure 2 The section of the exhaust section 8 near the airflow outlet 4 has a conical structure.
[0045] Specifically, the conical outlet design allows for a more stable discharge of the mixed airflow and facilitates matching with the interface of external inflation devices, such as inflation nozzles or hose connections.
[0046] Please refer to Figure 3 and Figure 4 This application embodiment also provides an air suspension air supply system, including a compressor 02, an air suspension module and any of the above-described auxiliary air intake enhancement devices 01, wherein the compressor 02 is connected to the auxiliary air intake enhancement device 01 and the air suspension module via pipelines.
[0047] It is worth noting that the system includes a compressor 02, an air suspension module, and an auxiliary air intake enhancement device 01. The compressor 02 is connected to the enhancement device and the suspension module via pipelines. This ensures the air supply needs of the suspension module under normal operating conditions, while simultaneously providing increased airflow to the required external device 05 through the enhancement device. The system achieves dual functions without increasing the power and size of the compressor 02, enhancing its application value and versatility. Compared to traditional technologies, this system can directly provide a stable airflow to the required external device 05 through the compressor 02 alone, expanding the system's functionality. The air suspension module includes an air tank and air springs, etc. It should be noted that other related equipment and their arrangement in the system can be designed and arranged according to corresponding requirements, as long as the requirements are met; no further restrictions are specified here.
[0048] In some embodiments, please refer to Figure 3 and Figure 4 A first control switch module is provided between the compressor 02 and the auxiliary air intake enhancement device 01; a second control switch module is provided between the compressor 02 and the air suspension module.
[0049] It should be noted that the first control switch module is located between the compressor 02 and the auxiliary air intake enhancement device 01, and the second control switch module is located between the compressor 02 and the air suspension module. By setting up two separate control switch modules, the system can switch between air suspension air supply and external device 05 inflation, ensuring the stability and safety of air supply under various operating conditions. Specifically, the first control switch module includes a first control valve 03, used to control the opening and closing of the airflow to its auxiliary air intake enhancement device 01, so as to realize the inflation of the external device 05; the second control switch module includes multiple sets of second control valves 04, which are respectively used to control the gas exchange between the air spring and the air tank in the air suspension module, so as to realize the raising and lowering of the vehicle height.
[0050] In summary, the auxiliary air intake enhancement device in this invention, through the arrangement of a flow structure and a nozzle structure, accelerates the working airflow within the flow channel of the nozzle structure and forms a low-pressure zone at the outlet. This allows the auxiliary mixing air intake to draw in external airflow, mixing it with the working airflow within the airflow channel before discharge through the airflow outlet. This structural design effectively draws in additional atmospheric air into the airflow channel even with limited compressor airflow, significantly increasing the total output airflow and solving the problem of insufficient air supply efficiency caused by the low power of existing compressors. The air suspension air supply system in this invention combines a compressor, an air suspension module, and an auxiliary air intake enhancement device. This allows the compressor to not only perform the conventional air supply function of the air suspension module but also provide enhanced airflow to external devices through the auxiliary air intake enhancement device, enabling a single compressor to be used in dual applications under different operating conditions. This system improves the flow rate and efficiency of external air supply without increasing the compressor's size or power, shortens inflation time, and expands the application scenarios of the air suspension module.
