[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model discloses a portable pulmonary function testing device, comprising: a testing device 1, wherein a rotating groove 2 is provided inside the testing device 1, and the interior of the rotating groove 2 is connected to the upper surface of the testing device 1; the rotating groove 2 provides rotation space for the air intake pipe 3, allowing the air intake pipe 3 to rotate flexibly within the testing device 1, facilitating adjustment of the gas transmission direction to adapt to different testing scenarios; simultaneously, its design of being connected to the upper surface facilitates docking of the air intake pipe 3 with external components; the output end of the testing device 1 is fixedly connected to the air intake pipe 3; the air intake pipe 3 serves as the gas output channel of the testing device 1, stably transmitting the gas generated or processed by the testing device 1 to subsequent components, ensuring the continuity and accuracy of gas transmission. For accuracy, connecting pipes 10 are fixedly connected to both the left and right sides of the outer surface of the main intake pipe 3. Connecting pipes 10 are connected to the main intake pipe 3, realizing gas diversion and transmission, evenly distributing the gas in the main intake pipe 3 to the connecting pipes 10 on both sides, providing a suitable gas flow rate for subsequent testing operations. A second mating groove 12 is provided inside the connecting pipe 10, and the interior of the second mating groove 12 is connected to the outer surface of the connecting pipe 10. The second mating groove 12 provides space for the installation and rotation of the rotating pipe 14. Its design of being connected to the outer surface of the connecting pipe 10 facilitates gas exchange between the rotating pipe 14 and the outside, while ensuring the installation stability of the rotating pipe 14 within the connecting pipe 10. The interior of the 12 is provided with a rolling groove 11, and the interior of the rolling groove 11 is connected to the interior of the second mating groove 12. The rolling groove 11 cooperates with the ball 13 in the fitting groove 15, providing a smooth track for the rotation of the rotating tube 14, allowing the rotating tube 14 to rotate flexibly within the second mating groove 12. At the same time, the connection design ensures that the ball 13 can roll freely within the rolling groove 11. The rotating tube 14 is fitted inside the second mating groove 12, achieving a tight connection with the connecting tube 10, and can rotate within the second mating groove 12 to adjust its own angle to meet the requirements of gas transmission direction and position during different detections. The rotating tube 14 has four fitting grooves 15 inside, and the inside of the fitting grooves 15 is connected to the inner wall of the rotating tube 14. The fitting grooves 15 are used to install the balls 13. The design of the fitting grooves 15 being connected to the inner wall of the rotating tube 14 allows the balls 13 to fully contact the rolling grooves 11, providing the necessary support and lubrication for the rotation of the rotating tube 14 and ensuring the flexibility of rotation. The fitting grooves 15 are rotatably connected to the balls 13, and the outer surface of the balls 13 is rotatably connected to the inner surface of the rolling grooves 11. The balls 13 roll in the rolling grooves 11, which greatly reduces the friction when the rotating tube 14 rotates, allowing the rotating tube 14 to rotate easily and smoothly, improving the operation convenience and stability of the equipment.

[0024] There are two connecting pipes 10, and the number of rotating pipes 14 corresponds to the number of connecting pipes 10. Two connecting pipes 10 and two corresponding rotating pipes 14 work together to achieve dual-path gas flow transmission, increasing the efficiency and stability of gas transmission. The symmetrical design ensures the balance of the equipment. The size of the rotating pipe 14 matches the size of the rotating groove 2. This matching relationship ensures that the rotating pipe 14 will not interfere with the rotating groove 2 during rotation, guaranteeing that the rotating pipe 14 can rotate freely within the rotating groove 2. This also makes the entire gas transmission system structure more compact and reasonable. The main inlet pipe 3 is located inside the rotating groove 2, making its rotation more stable. The moving groove 2 provides some protection for the main air intake pipe 3, preventing it from being interfered with by external factors and ensuring the stability of gas transmission. A display screen 4 is fixedly connected to the upper surface of the detector 1. The display screen 4 is fixed to the upper surface of the detector 1, allowing users to intuitively view test data and equipment status information, providing a clear interactive interface for easy understanding of test results. Four control buttons 5 are located on the side wall of the display screen 4, and all four control buttons 5 are connected to the upper surface of the detector 1. In conjunction with the display screen 4, users can operate the control buttons 5 to perform various function settings and operations on the detector 1, such as starting the test and viewing historical data, achieving effective interaction between the user and the detector 1. A power interface 6 is provided on the side wall. This provides a channel for the detector 1 to connect to an external power source, ensuring a stable power supply and maintaining its normal operation. This is crucial for the continuous operation of the equipment. The detector 1 has two first mating grooves 7 inside, both of which are connected to the front surface of the detector 1. These first mating grooves 7 provide installation space for components such as the limiting belt 9. Their connection to the front surface of the detector 1 facilitates the installation and use of the limiting belt 9, providing a basis for limiting items placed on the front surface of the detector 1. The two first mating grooves 7 are symmetrically arranged on the left side of the front surface of the detector 1. This symmetrical arrangement of the first mating grooves 7 ensures that the limiting belt 9 effectively controls the items. The balance and stability of the limiting mechanism allow the item to be uniformly limited, preventing it from shifting to one side. Positioning pins 8 are fixedly connected to the upper and lower sides of the inner surfaces of the two first mating grooves 7. These positioning pins 8 provide a track for the limiting belt 9 to be fixed and slidable, ensuring that the limiting belt 9 can slide stably within the first mating grooves 7, providing reliable support for the item's limitation. A limiting belt 9 is provided between the two positioning pins 8, and the inside of the limiting belt 9 is slidably connected to the positioning pins 8. Through this slidable connection, the limiting belt 9 can be adjusted in position as needed, limiting the item placed on the front surface of the detector 1, preventing it from moving randomly during the detection process, and ensuring the accuracy of the detection and the cleanliness of the equipment.

[0025] Working Principle: First, insert the power plug into the power interface 6 on the side wall of the detector 1 to power the detector and put the equipment into working condition. The power interface 6 provides the necessary power support for the normal operation of the detector 1. Check whether the main air intake pipe 3, connecting pipe 10, rotating pipe 14 and other components are securely connected, ensuring that the ball bearing 13 can roll flexibly in the rolling groove 11 and that the limit belt 9 can slide freely on the positioning pin 8. Since the main air intake pipe 3 is located in the rotating groove 2, the main air intake pipe 3 can be rotated within the allowable range of the rotating groove 2 according to the actual testing needs to initially adjust the gas transmission direction. The rotating groove 2 provides rotation space for the main air intake pipe 3. By using the ball bearing 13 in the fitting groove 15 to roll in the rolling groove 11, the rotating pipe 14 can be flexibly rotated to a suitable angle to accurately adjust the gas transmission path. The second mating groove 12 in the connecting pipe 10 provides installation space for the rotating pipe 14 to ensure its rotation. To ensure stability during operation, press the control button 5 on the side wall of the display screen 4 to start the detection function of the detector 1. The control button 5 is used for user operation of the detector. The display screen 4 displays the detection data and equipment status in real time. The gas generated or processed by the detector 1 enters the main air intake 3 through the output end, and then is split into the connecting pipes 10 on the left and right sides through the main air intake 3. Finally, it is transmitted to the detection part through the rotating pipe 14. Place the auxiliary items required for detection (such as disposable mouthpieces) on the front surface of the detector 1, slide the limit belt 9 to move it on the positioning pin 8 to limit the items and prevent them from moving during the detection process. The first mating groove 7 provides the installation position for the limit belt 9 and other components. Press the control button 5 again to stop the detection work of the detector 1. Rotate the main air intake 3 and the rotating pipe 14 to return them to a position that is easy to store, reducing the space occupied by the detector and making it convenient to carry and store.
