Description

Technical Field

[0001] This utility model relates to the field of respirator testing technology, specifically a multifunctional integrated testing device for respirators. Background Technology

[0002] The multi-functional integrated testing device for respirators is mainly used to comprehensively test the performance parameters of various respirators. It can simulate different working conditions, quickly identify potential hazards such as equipment leakage and insufficient pressure, and ensure that respirators can be used reliably in high-risk environments such as fire fighting, chemical industry, and mining, thus protecting user safety. It is an important piece of equipment for the daily maintenance and periodic calibration of respirators.

[0003] However, in practical use, existing technologies for simulating lung contraction often employ a single linkage or cylinder for direct drive, resulting in problems such as insufficient transmission stability, limited range of respiratory parameter adjustment, and low accuracy in simulating real respiratory curves. For example, single linkage transmission is prone to generating lateral forces, leading to uneven stress on the flexible airbag and affecting the detection data. Cylinder-driven methods are difficult to accurately simulate the nonlinear flow changes during human respiration. Furthermore, most bionic heads and bionic lungs are different devices that need to be connected in series, and the connection of the airway is complex, requiring frequent insertion and removal of pipes, which affects the continuity of the detection process. In view of this, we propose a multifunctional integrated detection device for respirators. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional integrated testing device for respirators to solve the problems mentioned in the background art.

The outer wall of the driven rod is slidably connected to the upper inner wall of the body. The bionic head is connected to a bionic lung via a trachea. The upper surface of the bionic lung is fixedly connected to the lower surface of the driven rod.

[0007] Preferably, the fixing plate also includes an airflow detector, the outer wall of which is installed on the inner wall of the trachea, and motion detectors are installed on both the upper and lower sides of the front surface of the bionic lung.

[0013] Compared with the prior art, this utility model provides a multi-functional integrated testing device for respirators, which has the following beneficial effects:

[0014] 1. This multifunctional integrated detection device for respirators integrates the bionic head and bionic lung into the same device through a dual-bar assembly for respiratory rhythm. During use, the device repeatedly inserts and removes tubes between the two, while the driven rod and swing plate pull the upper side of the bionic lung, making the motion curve of the bionic lung smoother.

[0015] 2.

In turn, adjusting the slider adjusts the movement of the driven rod, enabling the device to simulate the breathing characteristics of different populations. At the same time, the guide cylinder further stabilizes the movement of the driven rod. Attached Figure Description

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a multifunctional integrated detection device for a respirator, including a body 1 for supporting the overall structure, a control panel 2 for controlling the operation of the device and simultaneously connecting to the airflow detector 611 and the motion detector 63 on the front surface of the body 1, a shielding box 3 for separating the respiratory rhythm double rod assembly 6 from the outside world fixedly connected to the upper surface of the body 1, a rotating shaft 4 for supporting the rotation of the box door 5 fixedly connected to the left side of the front surface of the shielding box 3, a box door 5 for sealing the shielding box 3 rotatably connected to the outer wall of the rotating shaft 4, a mounting platform 7 for fixing the bionic head 8 fixedly connected to the lower surface of the inner wall of the shielding box 3, a bionic head 8 for detecting the respirator installed on the upper side of the outer wall of the mounting platform 7, and a respiratory rhythm double rod assembly 6 for stabilizing and controlling the expansion and contraction of the bionic lung 62 on the upper surface of the shielding box 3.

[0024] The respiratory rhythm dual-bar assembly 6 includes a fixing plate 64 for fixing and supporting a motor 65. The lower surface of the fixing plate 64 is fixedly connected to the upper surface of the shielding box 3. The right surface of the fixing plate 64 is fixedly connected to a motor 65 for driving a rotating shaft 66 to rotate. The outer wall of the output shaft of the motor 65 is fixedly connected to a rotating shaft 66 for driving a rotating disk 67 to rotate. The right surface of the rotating shaft 66 is fixedly connected to a rotating disk 67 for pressing a slider 610 to make the slider 610 rotate. The inner wall of the rotating disk 67 is slidably connected to a screw 92 for driving an adjusting screw 92 to rotate. The slider 610 is movable. The right surface of the slider 610 is connected to a swing rod 68 via an adjustment component 9, which drives the driven rod 69 to move vertically through its own movement. The lower inner wall of the swing rod 68 is rotatably connected to the driven rod 69, which is used to pull the upper side of the bionic lung 62 to control the breathing rhythm of the bionic lung 62. The outer wall of the driven rod 69 is slidably connected to the upper inner wall of the body 1. The bionic head 8 is connected to the bionic lung 62 via a trachea 61, which is used to keep the device within the detection range of the enhancement device. The upper surface of the bionic lung 62 is fixedly connected to the lower surface of the driven rod 69.

[0025] In one embodiment of this utility model, the fixing plate 64 further includes an airflow detector 611 for detecting the flow of gas inside the trachea 61. The outer wall of the airflow detector 611 is installed on the inner wall of the trachea 61. Motion detectors 63 for detecting the extension distance of the bionic lung 62 are installed on both the upper and lower sides of the front surface of the bionic lung 62. The thickness of the slider 610 is less than the groove width of the inner wall of the rotating disk 67. The adjusting assembly 9 includes a fixing sleeve 91 for supporting the rotation of the adjusting screw 92 and driving the swing rod 68 to move. The outer wall of the fixing sleeve 91 passes through and is rotatably connected to the upper inner wall of the swing rod 68. The inner wall of the fixing sleeve 91 is threadedly connected to an adjusting screw 92 for adjusting or fixing the slider 610 by rotating it.

[0026] In an embodiment of this utility model, a knob 93 is fixedly connected to the right surface of the adjusting screw 92 for convenient rotation by the operator. The right surface of the slider 610 is rotatably connected to the left surface of the adjusting screw 92. A guide cylinder 612 for limiting and guiding the movement of the driven rod 69 is slidably connected to the outer wall of the driven rod 69. The outer wall of the guide cylinder 612 is fixedly connected to the upper inner wall of the shielding box 3. A wear-resistant ring 613 is embedded in the inner wall of the guide cylinder 612 to support the inner wall of the adjusting screw 92 and enhance the overall strength of the device. The inner diameter of the wear-resistant ring 613 is clearance-fitted with the outer diameter of the driven rod 69.

[0027] In this invention, during use, the breathing mask is first installed on the bionic head 8. Then, the adjustment component 9 is adjusted according to the detection results. First, the knob 93 is rotated. During the rotation of the knob 93, the fixing sleeve 91 rotates, causing the slider 610 to gradually move away from the inner wall of the rotating disk 67. Then, the swing rod 68 is moved downwards. The movement of the swing rod 68 causes the driven rod 69 to move, thereby changing the maximum stroke of the bionic lung 62. This allows the device to be adjusted and adapted to different lung capacities, enhancing the applicability of the device. Then, the airflow detector 611 and motion detector 63 are turned on through the control panel 2, so that the operating data of the device can be monitored and recorded by the control panel 2. Then, gas is introduced into the breathing mask, and simultaneously through the control panel... 2. When motor 65 is turned on, its output shaft drives the rotating shaft 66 to rotate. The rotation of the rotating shaft 66 causes the rotating disk 67 to rotate as well. The inner wall of the rotating disk 67 will press the slider 610, causing the slider 610 to drive the adjusting screw 92 to rotate. The fixed sleeve 91 will move synchronously and drive one end of the swing rod 68 to perform a circular motion. Because the driven rod 69 is limited by the guide cylinder 612 and the shielding box 3, the driven rod 69 can move vertically up and down, thereby stably controlling the opening and closing of the bionic lung 62. The motion detector 63 will detect the movement distance. With the cooperation of the airflow detector 611, the operator can see more intuitive data on the control panel 2, which facilitates subsequent judgment.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
