Description

Technical Field

[0001] This utility model relates to the field of respirator technology, specifically a comprehensive respirator testing instrument. Background Technology

[0002] The overall performance of a respirator is an important technical indicator for classifying the quality of respirator products and is used to guide the quality control of respirators. In recent years, with the rapid growth of the demand for respirators in my country and around the world, the quality of respirators has become an increasingly worrying issue, and many product quality problems of respirators have become increasingly prominent.

[0003] According to a respirator comprehensive testing instrument (announcement number: CN219245011U) published in the above application, the silicone corrugated cover used in the above application replaces the traditional cylinder. It is elastic and can realistically simulate human breathing. The silicone human head model used ensures the airtightness of the respirator mask after wearing. The pressure sampling port at the upper end of the pressure sampling tube is moved from inside the mouth of the human head model to the eye position, thereby effectively avoiding the pressure instability caused by air flow in the mouth, improving the accuracy of the test, and thus being able to test masks of different heights and types, accurately detect and improve the efficiency of the test.

[0004] However, in actual use, although the above-mentioned equipment can conduct tests on different types of masks, dust will continuously accumulate in the air chamber during the experiment, which will eventually affect the subsequent test results; in view of this, we propose a comprehensive respirator tester. Utility Model Content

[0005] The purpose of this invention is to provide a comprehensive respirator testing instrument to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a comprehensive respirator testing instrument, comprising a body, an upper mounting frame provided on the outer wall of the body, a simulated air outlet seat provided on the outer wall of the upper mounting frame, a detection and discharge assembly provided on the outer wall of the body, the detection and discharge assembly comprising a lower mounting frame, the lower mounting frame being fixedly connected to the outer wall of the body, a hydraulic rod being fixedly connected to the inner wall of the lower mounting frame, and a mounting base plate being fixedly connected to the end of the hydraulic rod;

[0007] A corrugated pipe is fixedly connected to the outer wall of the mounting base plate. The corrugated pipe is fixedly connected to the outer wall of the upper mounting frame. A discharge vertical rod is fixedly connected to the outer wall of the lower mounting frame. A side plate is fixedly connected to the outer wall of the lower mounting frame. An arc-shaped rubber block is fixedly connected to the outer wall of the side plate.

[0008] Preferably, the centerline of the upper mounting bracket is on the same straight line as the centerline of the corrugated pipe and the centerline of the lower mounting bracket.

[0009] Preferably, the mounting base plate is slidably connected to the outer wall of the discharge vertical rod, and the inner wall of the mounting base plate is adapted to the outer wall of the discharge vertical rod.

[0010] Preferably, the number of the arc-shaped adhesive blocks is several, and the several arc-shaped adhesive blocks are arranged in a linear array on the outer wall of the side plate.

[0011] Preferably, the outer wall of the corrugated pipe is provided with a guide assembly, the guide assembly includes a movable slider, the movable slider is fixedly connected to the outer wall of the corrugated pipe, and the outer wall of the lower mounting bracket is fixedly connected with a guide rod.

[0012] Preferably, the movable slider is slidably connected to the outer wall of the guide rod, and the inner wall of the movable slider is adapted to the outer wall of the guide rod.

[0013] Preferably, the centerline of the guide rod, the centerline of the bellows, and the centerline of the machine body are all on the same plane.

[0014] Compared with the prior art, the present invention provides a comprehensive respirator testing instrument, which has the following beneficial effects:

[0015] 1. In daily use, this respirator comprehensive testing instrument allows users to wear different masks on the simulated air outlet seat. Then, the hydraulic rod can be activated to extend and retract, causing the mounting base plate to deform during lifting and lowering, simulating the breathing state of the lungs. During the lifting and lowering of the mounting base plate, the discharge vertical rod guides the movement, and as the mounting base plate reaches its bottom, the discharge vertical rod thins, exposing the holes in the mounting base plate. This facilitates the discharge of debris and dust particles from the mounting base plate and the bellows. Simultaneously, the bellows is periodically agitated by the arc-shaped rubber blocks on the side plate during displacement, ultimately promoting better discharge of dust particles from the bellows through vibration, ensuring the accuracy of the simulation.

[0016] 2. In this comprehensive respirator testing instrument, when the mounting base plate and the corrugated pipe are displaced and raised, the movable slider will move synchronously on the outer wall of the guide vertical rod, so that the mounting base plate and the corrugated pipe can be raised and lowered more smoothly. This allows the airflow to be discharged smoothly and evenly when the corrugated pipe contracts and expands, which also improves the accuracy of mask testing and the overall practicality.

[0023] Furthermore, the corrugated pipe 404 is fixedly connected to the outer wall of the mounting base plate 403, the corrugated pipe 404 is fixedly connected to the outer wall of the upper mounting bracket 2, the lower mounting bracket 401 is fixedly connected to the outer wall of the discharge vertical rod 405, the lower mounting bracket 401 is fixedly connected to the outer wall of the side plate 406, and the side plate 406 is fixedly connected to the outer wall of the arc-shaped rubber block 407.

[0024] In the embodiments of this utility model, the center line of the upper mounting bracket 2, the center line of the corrugated pipe 404, and the center line of the lower mounting bracket 401 are all on the same straight line. The mounting base plate 403 is slidably connected to the outer wall of the discharge vertical rod 405, and the inner wall of the mounting base plate 403 is adapted to the outer wall of the discharge vertical rod 405. The number of arc-shaped rubber blocks 407 is several, and the several arc-shaped rubber blocks 407 are arranged in a linear array on the outer wall of the side plate 406.

[0025] Furthermore, the outer wall of the bellows 404 is provided with a guide assembly 5, which includes a movable slider 502. The movable slider 502 is fixedly connected to the outer wall of the bellows 404. The outer wall of the lower mounting bracket 401 is fixedly connected with a guide vertical rod 501. The movable slider 502 is slidably connected to the outer wall of the guide vertical rod 501, and the inner wall of the movable slider 502 is adapted to the outer wall of the guide vertical rod 501.

When the mounting base plate 403 is lifted and lowered, the discharge vertical rod 405 will guide it. When the mounting base plate 403 is moved to the bottom, the discharge vertical rod 405 will change from thick to thin. At this time, the holes of the mounting base plate 403 will be exposed, which will facilitate the discharge of debris and dust particles in the mounting base plate 403 and the bellows 404. At the same time, when the bellows 404 is displaced, it will be periodically rubbed by the arc-shaped rubber block 407 on the side plate 406. Finally, through vibration, the dust particles in the bellows 404 can be better discharged, ensuring the accuracy of the simulation.

[0027] When the mounting base plate 403 and the corrugated pipe 404 are displaced and raised, the movable slider 502 will move synchronously on the outer wall of the guide vertical rod 501, so that the mounting base plate 403 and the corrugated pipe 404 can be raised and lowered more smoothly. This allows the airflow to be discharged smoothly and evenly when the corrugated pipe 404 contracts and expands, which also improves the accuracy of mask testing and the overall practicality.

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.
