Description

Technical Field

[0001] This utility model relates to the field of air vents, and more particularly to a zero-leakage air vent with a leak detection indicator. Background Technology

[0002] In cleanrooms, medical operating rooms, and other environments with extremely high requirements for air cleanliness and airtightness, air vent systems must use built-in filters to intercept pollutants such as dust and microorganisms in the air, while ensuring zero leakage of the entire vent. If there is a leak in the filter or the connection of the vent, unfiltered polluted air will directly seep into the clean area, leading to a decrease in product yield or cross-infection.

[0003] The current mainstream vent leakage detection solutions in the industry mainly rely on external mobile detection devices or fixed single-point detection structures.

[0004] However, external mobile detection devices are cumbersome to operate and prone to blind spots, while fixed single-point detection has a limited detection range and cannot locate the leak. Therefore, a zero-leakage air outlet with a leak detection indicator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a zero-leakage air outlet with a leak detection indicator, which aims to solve the problem that the prior art cannot fully detect leaks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a zero-leakage air outlet with a leak detection indicator, comprising an air outlet body, a fixing plate fixedly connected to the bottom of the inner wall of the air outlet body, a bearing provided on the top of the fixing plate, the outer wall of the bearing fixedly connected to the top of the fixing plate, and a spiral rod fixedly connected to the inner wall of the bearing, and a handle fixedly connected to the top of the spiral rod.

[0007] The outer wall of the spiral rod is threaded with a spiral sleeve, and the outer wall of the spiral sleeve is fixedly connected to a mounting base. The mounting base has mounting holes on its front and back sides, and a detection device is fixedly installed on the inner wall of the mounting hole.

[0008] As a further description of the above technical solution: the bottom of the inner wall of the air outlet body is fixedly connected to a limiting groove, the side of the mounting base is fixedly connected to a limiting block, and the outer wall of the limiting block is slidably connected to the inner wall of the limiting groove.

[0009] As a further description of the above technical solution: a position indicator device is fixedly installed on the inner wall of the air outlet body, and the position indicator device is signal connected to the detection device.

[0010] As a further description of the above technical solution: a glass door is hinged to the front of the air vent body, and a handle is provided on the front of the glass door.

[0011] As a further description of the above technical solution: the inner wall of the air vent body is fixedly connected with a fixing buckle, and the air vent body is fixedly connected with an installation plate through the fixing buckle.

[0012] As a further description of the above technical solution: the front of the mounting plate is rotatably connected with two rotating buckles, which are located at the top and bottom of the front of the mounting plate, respectively.

[0013] As a further description of the above technical solution: the front side of the mounting plate is fixedly connected with four positioning pins, which are symmetrically arranged on both sides of the front side of the mounting plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the transmission structure of the handle, the screw rod, and the screw sleeve drives the mounting base and the detection device to slide up and down along the air outlet body, which can cover the entire end face and edge sealing area of ​​the filter, completely eliminating blind spots such as the top and corners; at the same time, the detection device and the position indicator are linked, and once a leak is detected, the position indicator can provide real-time feedback on the current position of the detection device, directly locking the leak point and providing accurate guidance for subsequent maintenance.

[0016] 2. In this utility model, the testing process does not require disassembling the air vent or using an external mobile instrument. Simply open the front glass door and turn the handle to drive the testing device to complete the full range of testing. The operation steps are simplified, and the testing time for a single test is greatly shortened compared to traditional external testing, reducing the impact on cleanroom production and operating room surgery arrangements.

The mounting base 7 has mounting holes on its front and back sides to facilitate the installation and testing of the detection device 8. The detection device 8 is fixedly installed on the inner wall of the mounting hole. The bottom of the inner wall of the air outlet body 1 is fixedly connected to a limiting groove 9. The side of the mounting base 7 is fixedly connected to a limiting block 10, and the outer wall of the limiting block 10 is slidably connected to the inner wall of the limiting groove 9 to limit the mounting base 7, so that the mounting base 7 can only rise and fall but cannot rotate, thereby making the rising and falling of the spiral sleeve 6 more stable. The inner wall of the air outlet body 1 is fixedly installed with a position indicator 11, and the position indicator 11 is signal connected to the detection device 8, which can effectively display the position information of the inspection device.

[0023] Reference Figure 1 The air vent body 1 has a glass door 12 hinged to its front, and a handle 13 is provided on the front of the glass door 12 for easy opening. A fixing buckle 15 is fixedly connected to the inner wall of the air vent body 1. An installation plate 14 is fixedly connected to the air vent body 1 through the fixing buckle 15. The installation plate 14 is used to install the filter. Two rotating buckles 16 are rotatably connected to the front of the installation plate 14.

[0024] Working principle: The filter is installed by rotating the buckle 16 and mounting plate 14. When leakage detection of the filter is required, the glass door 12 is opened and the handle 5 is turned. The handle 5 drives the spiral rod 4 to rotate. Under the action of the limit groove 9 and the limit block 10, the spiral sleeve 6 is adjusted to rise and fall. The rise and fall of the spiral sleeve 6 drives the mounting base 7 to rise and fall, thereby driving the detection device 8 to perform detection and conduct a comprehensive inspection of the filter. When a leak is detected, the position indicator device 11 senses the position of the detection device 8 to determine the location of the leak.
