Description

Technical Field

[0001] This invention relates to the field of air pulse output equipment technology, and specifically to a portable continuous air output device for air pulse equipment. Background Technology

[0002] In practical applications, air pulse equipment often requires the use of miniaturized, portable air output devices, especially in field or on-site environments where there is no fixed power supply and the working space is limited. There is a pressing need for compatible devices that can stably output pulsed air, are easy to carry, and can be quickly connected to the air pulse equipment. Currently available air output devices for air pulse equipment generally suffer from incompatibility with these application requirements. Most devices, in pursuit of higher output power, are bulky and cumbersome, resulting in extremely poor portability and failing to meet the needs of mobile air pulse equipment operations. Furthermore, they lack convenient connection structures, making docking with the air pulse equipment cumbersome, and the connection lacks stability, easily leading to detachment or seal failure during operation.

[0003] Some miniaturized devices, due to unreasonable transmission structure design, struggle to achieve stable pulsed air output within a compact space. The pulse frequency and pressure fluctuations of the output airflow are significant, failing to provide the required air source support for gas pulse equipment. Furthermore, many of these small devices lack gas pressure monitoring capabilities, making it impossible for operators to monitor gas delivery parameters in real time and adjust them precisely according to the operational status of the gas pulse equipment. Some devices also rely on external power supply, further limiting their portability. In addition, the sealing structures of existing devices are mostly designed for large equipment; miniaturization reduces sealing performance, making gas leakage during transmission and output prone to occur. This not only reduces delivery efficiency but also affects the operational stability of the gas pulse equipment. Some devices also have loose assembly layouts, making them susceptible to component loosening and malfunctions during transport, resulting in insufficient overall reliability and failing to fully meet the core usage requirements of gas pulse equipment: small size, portability, stable pulsed air delivery, and convenient connection. Therefore, based on the aforementioned problems and deficiencies, those skilled in the art propose a portable continuous air output device solution for gas pulse equipment that can solve these issues.

[0030] The portable continuous air output device for air pulse equipment disclosed in this embodiment has a core component of a pulse gas output device 1. A housing 2 is fixedly connected to the top end face of the pulse gas output device 1. A lithium battery 7 is fixed to the left side of the top surface of the housing 2, and a digital display screen 8 is fixed to the right side of the top surface of the pulse gas output device 1. An inlet pipe 4 and an output pipe 5 are respectively mounted at the front and rear ends of the pulse gas output device 1, with a gas pressure sensor 6 fixed through the top of the output pipe 5. The pulse gas output device 1 consists of a chamber 1-1 and end caps 1-2. End caps 1-2 are fixed to the upper and lower end faces of the chamber 1-1, respectively. Two symmetrical semi-circular spaces are arranged inside the chamber 1-1. A driven gear column 1-3 and a driving gear column 1-6 are rotatably disposed within the inner cavity of the chamber 1-1, meshing and rotating within the semi-circular spaces to form a pulsed air output structure. Sealing gaskets are installed between the upper and lower end faces of the hull 1-1 and the end cover 1-2. Shaft seats are installed on the left and right sides of the end faces of the end cover 1-2 that are close to each other. The driven gear column 1-3 and the driving gear column 1-6 are respectively rotatably assembled on the corresponding shaft seats, and the rotation trajectory of the two is restricted by the shaft seats. The top of the driving gear column 1-6 is fixedly connected to the transmission shaft 1-5, which extends through to the top of the hull 1-1. The bottom end of the driven gear 1-4 is fixedly connected to the top end of the transmission shaft 1-5. When the driving gear column 1-6 rotates, it can drive the transmission shaft 1-5 and the driven gear 1-4 to rotate synchronously.

[0031] A fixed bracket is mounted on the right side wall of the chamber 1-1, on which the servo frequency converter motor 1-8 is installed. The top output shaft of the servo frequency converter motor 1-8 is fixed to the drive gear 1-7 via a coupling. The drive gear 1-7 meshes with the driven gear 1-4. The servo frequency converter motor 1-8 drives the drive gear 1-7 to rotate, which in turn drives the driven gear 1-4, the transmission shaft 1-5, and the driving gear column 1-6 to rotate. During the rotation of the driving gear column 1-6, it meshes with the driven gear column 1-3 for transmission. Air inlet and outlet ports are provided on both the front and rear end faces of the chamber 1-1. Connecting heads 3 are fixed to the air inlet pipe 4 and the outlet pipe 5 via bolts. The air inlet pipe 4 and the outlet pipe 5 are respectively fixed to the front and rear side walls of the chamber 1-1 via corresponding connecting heads 3, achieving communication and fixation between the air inlet pipe 4 and the outlet pipe 5 and the chamber 1-1. An opening is provided on the top surface of the outlet pipe 5, and a gas pressure sensor 6 is embedded through this opening. The gap between the opening and the gas pressure sensor 6 is filled and sealed with industrial sealant to achieve a sealed fit between the two. A control motherboard is fixedly connected to the top surface of the inner cavity of the outer casing 2. Control buttons are installed on the front side wall of the outer casing 2 and are electrically connected to the control motherboard. The control motherboard is electrically connected to the servo frequency converter motors 1-8, the lithium battery 7, the digital display screen 8, and the gas pressure sensor 6. The control buttons can trigger the control motherboard to issue commands to regulate the display status of the digital display screen 8 and the operating status of the servo frequency converter motors 1-8. The signal detected by the gas pressure sensor 6 is transmitted to the control motherboard, processed, and displayed on the digital display screen 8. A charging port is provided on the front of the drive gear 1-7 and is electrically connected to the lithium battery 7. Electrical energy can be input to the lithium battery 7 through the charging port, and the lithium battery 7 provides working power for the control motherboard, the servo frequency converter motors 1-8, the digital display screen 8, and the gas pressure sensor 6. The end cover 1-2 is fixedly connected to the chamber 1-1 by fasteners, and a sealing gasket is attached to the mating surface between the chamber 1-1 and the end cover 1-2 to prevent gas leakage from the mating surface. The bearing seat and end cover 1-2 are embedded, and the inside of the bearing seat is adapted to the ends of the driven gear column 1-3 and the driving gear column 1-6 to ensure coaxiality during rotation. The connection between the bracket and the cabin 1-1 is tight. After the servo frequency converter motor 1-8 is fixed on the bracket, its output shaft is aligned with the center line of the coupling. The two ends of the coupling are fixed to the output shaft of the servo frequency converter motor 1-8 and the drive gear 1-7, respectively, to reduce vibration interference during power transmission. The connector 3 is fitted with the mating surface of the air inlet and outlet ports of the cabin 1-1. The bolts are evenly distributed around the circumference of the connector 3. After tightening the bolts, the connector 3 is firmly connected to the air inlet and outlet ports. The air inlet pipe 4 and the output pipe 5 are inserted into the corresponding connector 3 and fixed, realizing communication with the internal space of the cabin 1-1.

[0032] The detection end of the gas pressure sensor 6 extends into the output tube 5, and its signal output end is connected to the control motherboard via a wire hidden in the internal gap between the housing 2 and the pulse gas output device 1. Control buttons are evenly arranged along the front sidewall of the housing 2, each button corresponding to a specific function. Operators can start / stop the device and adjust its operating parameters by pressing the control buttons. The electrodes of the lithium battery 7 are connected to the power interface of the control motherboard via wires. The control motherboard integrates a signal processing module, a drive module, and a power management module. The signal processing module receives and converts the detection signal transmitted by the gas pressure sensor 6. The drive module adjusts the operating status of the servo frequency converter motors 1-8 according to the processed signal and the instructions from the control buttons. The power management module distributes the output power of the lithium battery 7 to ensure stable power supply to all electrical components. The digital display screen 8 faces outwards for easy observation of relevant data. Its data receiving end is connected to the control motherboard via a data transmission line, receiving and displaying information such as gas pressure, battery level, and operating parameters of the servo frequency converter motors 1-8 in real time. The charging port interface adopts an anti-misinsertion structure. After an external charging device is inserted into the charging port through an adapter, it can charge the lithium battery 7. The relevant status during the charging process is displayed on the digital display screen 8. A sealing sleeve is installed at the penetration point between the drive shaft 1-5 and the top of the chamber 1-1. The sealing sleeve fits the outer circumference of the drive shaft 1-5 to prevent gas leakage from the chamber 1-1 through the penetration point. The tooth profiles of the driven gear column 1-3 and the driving gear column 1-6 are adapted to the semi-circular space inside the chamber 1-1. When the two mesh and rotate, they can change the volume of the corresponding area inside the chamber 1-1, which, together with the air intake pipe 4 and the output pipe 5, realizes the intake and pulsed output of gas. After the assembly of all the components of the entire device, a complete portable structure is formed. The fixing method of each connection part ensures the structural stability of the device during use. The coordinated cooperation of each functional component realizes continuous pulsed air output, meeting the usage requirements of air pulse equipment.

[0033] Workflow description of this technical solution:

[0034] The operator issues a start command by pressing the control button on the front side wall of the outer casing 2. The command is transmitted to the control mainboard at the top of the inner cavity of the outer casing 2. After receiving the command, the control mainboard distributes the power of the lithium battery 7 to the various electrical components through the power management module, providing power to the servo frequency inverter motors 1-8, the digital display screen 8, and the gas pressure sensor 6. The drive module of the control mainboard drives the servo frequency inverter motors 1-8 to start running according to the start command. The top output shaft of the servo frequency inverter motors 1-8 drives the coupling to rotate, and the coupling further drives the drive gear 1-7 to rotate. The drive gear 1-7 meshes with the driven gear 1-4, driving the driven gear 1-4 to rotate synchronously. The driven gear 1-4 drives the drive gear column 1-6 to rotate through the transmission shaft 1-5. The driving gear 1-6 rotates within the semi-circular space of the inner cavity of the chamber 1-1 and meshes with the driven gear 1-3. During this meshing and rotation, the volume of the corresponding area inside the chamber 1-1 changes, creating negative pressure that draws in outside air. This outside air enters through the intake pipe 4, passes through the connector 3, and enters the air inlet and outlet ports at the front and rear ends of the chamber 1-1, ultimately entering the interior of the chamber 1-1. As the driving gear 1-6 and driven gear 1-3 continue to mesh and rotate, the compressed air inside the chamber 1-1 enters the output pipe 5 through the air inlet and outlet ports and the connector 3, and is output in a pulsed manner from the output pipe 5, meeting the requirements of the gas pulse equipment. During the gas output process, the gas pressure sensor 6 continuously monitors the gas pressure inside the output pipe 5. The gas pressure is detected and converted into an electrical signal, which is then transmitted to the signal processing module of the control mainboard. The signal processing module processes the signal and transmits the relevant pressure data to the digital display screen 8. The digital display screen 8 displays real-time information such as gas pressure, lithium battery level 7, and operating parameters of the servo frequency converter motors 1-8. Operators can issue adjustment commands by pressing control buttons based on the information displayed on the digital display screen 8. Upon receiving the command, the control mainboard adjusts the operating speed of the servo frequency converter motors 1-8 through the drive module, thereby adjusting the meshing rotation speed of the drive gear column 1-6 and the driven gear column 1-3, achieving adjustment of the output gas pulse frequency and pressure. During operation, the upper and lower end faces of the chamber 1-1 and the end cover 1-2... The sealing gasket between the two parts prevents gas from leaking from the joint surface. The sealing sleeve at the penetration point between the drive shaft 1-5 and the top of the chamber 1-1 prevents gas from leaking from the penetration point. The industrial sealant between the top opening of the output pipe 5 and the gas pressure sensor 6 fills the gap to avoid gas leakage affecting the detection accuracy and output effect. When the device finishes working or needs to be stopped, the operator presses the control button to issue a stop command. After receiving the command, the control motherboard drives the servo frequency conversion motor 1-8 to stop running, the drive gear column 1-6 and the driven gear column 1-3 stop meshing and rotating, the gas intake and output process ends, and the control motherboard cuts off the power supply to each electrical component (the digital display screen 8 can retain a low power display state to display basic information such as battery level).If the lithium battery 7 has insufficient power, the digital display screen 8 will show a low battery warning. In this case, an external charging device needs to be connected via the charging port to charge the lithium battery 7. Once charging is complete, the device can be restarted.
