DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a PAO detection clean bench, such as Figure 1-4 As shown, the PAO detection clean bench includes: a workbench 1 for PAO detection, on which a static pressure box 2 is installed; a quick-connect connector 3 installed on the top of the static pressure box 2; a plug-in plug 4 arranged on the air inlet end of the quick-connect connector 3; a pull ring 5 fixed on the top of the plug 4; and a purification mechanism arranged in the static pressure box 2 for purifying gas.

[0022] It should be noted that traditional clean benches often use a more complicated injection method when injecting PAO. Operators need to use a variety of tools and equipment and go through multiple steps to complete the injection process. This not only requires operators to have high professional skills, but also increases the probability of errors during operation, further increasing the difficulty and complexity of detection; secondly, due to the cumbersome injection method, operators often need to adjust the position or angle of the clean bench many times to ensure that the PAO aerosol can be accurately injected. This adjustment not only consumes a lot of time and energy, but may also affect the stability and performance of the clean bench, especially when conducting batch testing. This frequent adjustment has become a key factor restricting work efficiency; in addition, the inconvenient PAO injection method may also cause aerosol leakage or uneven distribution. During the injection process, if the operation is improper or the equipment is not well sealed, the PAO aerosol may leak out from the injection port or other gaps, posing potential risks to the operating environment and personnel. At the same time, uneven aerosol distribution will also affect the accuracy and reliability of the test results, making it difficult for the test results to truly reflect the filtration performance of the clean bench. In summary, there are many inconveniences in the injection of PAO in the traditional clean bench, which not only increases the difficulty and complexity of the test, reduces work efficiency, but also may have a negative impact on the accuracy and reliability of the test results. Therefore, improvements and innovations are made to these problems, and a new type of clean bench with a convenient PAO injection function is developed, which is of great significance for improving the detection efficiency, ensuring the safety of operation, and improving the accuracy of the performance evaluation of the clean bench.

[0023] In this embodiment, the workbench 1 for PAO detection is the basic structure of the clean bench, which is used to provide a stable working platform to meet the needs of PAO detection.

[0028] In a further preferred embodiment of the utility model, a main power switch 13 is provided on the top of the static pressure box 2, an operation panel 14 is provided on one side of the workbench 1, and a plurality of universal casters 15 are symmetrically provided on the bottom of the workbench 1.

[0029] In this embodiment, a main power switch 13 is arranged on the top of the static pressure box 2, so that the startup and shutdown of the equipment are more convenient; the operator can control the power status of the entire workbench with just one button, without having to operate multiple switches separately; this not only improves work efficiency, but also reduces the possibility of misoperation and enhances the safety of the equipment; an operation panel 14 is arranged on one side of the workbench 1, which concentrates the main control buttons and display screen of the equipment; the design of the operation panel 14 enables the operator to easily adjust the working parameters of the equipment, monitor the equipment status, and perform necessary operations; this centralized control method simplifies the operating process and improves the intuitiveness and convenience of the operation; a number of universal casters 15 are symmetrically arranged at the bottom of the workbench 1, so that the entire workbench can be easily moved and positioned; the design of the universal casters 15 enables the workbench to adapt to different working environments and layout requirements, and is convenient for the operator to move it to the designated position. At the same time, the flexibility of the casters also improves the maneuverability of the equipment, and facilitates the transportation and storage of the equipment.

[0030] In a further preferred embodiment of the utility model, an operating port for personnel operation is provided on one side of the static pressure box 2, a glass sliding door 16 is provided on the inner side of the operating port, an electric telescopic rod for regulating the movement of the glass sliding door 16 is fixedly installed on the inner side of the static pressure box 2, and the output shaft of the electric telescopic rod is fixedly connected to the glass sliding door 16.

The output shaft of the electric telescopic rod is fixedly connected to the glass sliding door 16, and the opening and closing of the glass sliding door 16 are driven by the telescopic movement of the telescopic rod; this electric control method makes the operation more convenient and avoids the inconvenience and errors that may be caused by manual operation; at the same time, the precise control of the electric telescopic rod also ensures the sealing of the sliding door when it is closed, and prevents external pollutants from entering the plenum box 2.

[0032] In a further preferred embodiment of the utility model, an air inlet matched with the pre-filter 6 is arranged on the top of the static pressure box 2, and a diffuser mesh plate is arranged above the air inlet.

[0033] In this embodiment, an air inlet compatible with the pre-filter 6 is provided at the top of the static pressure box 2. This air inlet serves as the entrance for air to enter the static pressure box 2, and its design needs to match the size and shape of the pre-filter 6 to ensure that the air can smoothly pass through the pre-filter 6 for preliminary filtration. By reasonably designing the size and position of the air inlet, the air flow path can be optimized and the filtering efficiency of the entire purification mechanism can be improved; a diffuser mesh plate is provided above the air inlet. The function of the diffuser mesh plate is to evenly distribute the air entering the static pressure box 2 to avoid the situation where the local flow rate is too high or too low; through the diffuser effect of the mesh plate, the air can pass through the pre-filter 6 more evenly, thereby improving the filtering effect; at the same time, the diffuser mesh plate can also prevent large particles or foreign matter from directly entering the static pressure box 2, thereby protecting the pre-filter 6.
