Description

Technical Field

[0001] This utility model relates to the field of air conditioning repair equipment technology, and in particular to an air conditioning vent repair device. Background Technology

[0002] The air outlets / return vents of a central air conditioning system are crucial components for air circulation. Due to long-term operation, dust, bacteria, mold, and other pollutants easily accumulate inside the vents and connected ducts, severely impacting indoor air quality and human health, reducing heat exchange efficiency, and increasing energy consumption. Currently, routine cleaning, inspection, and maintenance (collectively referred to as oversight) of air conditioning vents primarily relies on manual methods. Workers typically use simple tools such as handheld lights, rags, brushes, and high-pressure air guns, reaching inside the vent grilles to perform the work. The existing technology suffers from the following problems: In pursuit of aesthetics, building renovations often employ recessed, elongated, or small-sized air vents. The gaps in these vents are extremely narrow, typically only 1-2 centimeters wide, making it difficult for conventional tools to penetrate them, and even arms cannot directly enter. This results in only a rough cleaning of the near-end area of ​​the vent, leaving contaminants deep within the duct walls, corners, and dead zones ineffective. The cleaning effect is significantly reduced, and bacterial growth remains unaddressed. Furthermore, workers cannot directly observe the contamination level and internal structure of the vent from the outside, relying heavily on feel and experience, leading to considerable uncertainty and missed areas. Existing tools are not specifically designed for vent maintenance; their functions are fragmented, often requiring multiple tool changes for cleaning, lighting, and inspection. Operators must repeatedly insert and remove tools, a cumbersome process that makes the entire maintenance operation time-consuming, labor-intensive, inefficient, and costly. Utility Model Content

[0003] The main purpose of this utility model is to provide an air conditioning vent inspection and maintenance device, which can effectively solve the problems of incomplete cleaning of air conditioning vents, blind operation, scattered functions, and low efficiency in the prior art.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, an air conditioning vent inspection device includes an operation panel 1. An insertion detection plate 2 is fixedly installed on one side of the operation panel 1, and a display panel 4 is fixedly installed on the other side of the operation panel 1. An air tester 3 is installed at the end of the insertion detection plate 2 away from the operation panel 1. The operation panel 1 has a sliding hole 11 that runs through the front and back. The insertion detection plate 2 has a compression groove 21 that runs through the top and bottom. A sliding hole 22 that runs through the sliding hole 11 is opened on the rear side of the inner wall of the compression groove 21. A pull-out slide rod 23 is slidably installed in the inner cavity of the sliding hole 22. The front end of the pull-out slide rod 23 extends through the compression groove 2. The inner cavity of the control panel 1 has a pull ring 231 fixedly installed on the rear end of the pull slide rod 23 through the sliding hole 11. The pull slide rod 23 has a vertically through groove 232. A limit slide rod 233 is fixedly installed between the front and rear sides of the inner wall of the groove 232. A slider 234 is slidably installed on the outer wall of the limit slide rod 233. Elastic plates 235 are fixedly installed at both the upper and lower ends of the slider 234. The ends of the two elastic plates 235 away from the slider 234 are fixedly connected to the frontmost sides of the upper and lower ends of the pull slide rod 23. Cleaning cotton strips 236 are adhered to the surface of the two elastic plates 235. To clean the inner wall of the air duct, pull the ring 231 to move the sliding rod 23 backward. The slider 234 will press against the rear side of the squeezing groove 21, thereby causing the elastic plate 235 to bend and the cleaning cotton strip 236 on its surface to contact the inner wall of the air duct. Since the elastic plate 235 has a certain elasticity, the cleaning cotton strip 236 can adapt to the inner wall surface with different curvatures to achieve effective wiping. Repeatedly pushing and pulling the sliding rod 23 can complete multiple cleanings of the inner wall of the air duct.

[0017] like Figure 4 As shown, the upper and lower ends of the insertion detection plate 2 are provided with two positioning holes 25 on the rear side of the extrusion groove 21, and the inner cavity of the upper and lower positioning holes 25 is fitted with positioning blocks 242. A cleaning mounting plate 24 is fixedly installed on one end of the positioning block 242. The two cleaning mounting plates 24 are located on the upper and lower sides of the insertion detection plate 2, respectively, and the side of the two cleaning mounting plates 24 away from the insertion detection plate 2 is glued with air guide plate cleaning cotton 241. The front and rear sides of the positioning block 242 are fixedly installed with arc rubber pads 243 to enhance the sealing and stability when the connection is made. The left and right ends of the insertion detection plate 2 are fixedly installed with light strip fixing plates 26. LED light strips 261 are fixedly installed on the three sides of the light strip fixing plates 26 for lighting inside the air vent, which facilitates direct inspection of the situation inside the dim air vent.

[0018] The cleaning cotton 241 on the air guide plate 24 can be used to clean the surface of the air guide plate. The cleaning plate 24 is fixed by the positioning block 242 and the positioning hole 25. It is easy to install and disassemble, and easy to replace or clean the cleaning cotton.

[0019] like Figure 5As shown, a C-shaped mounting plate 27 is fixedly installed at the front end of the insertion detection plate 2. The C-shaped mounting plate 27 consists of a vertical plate and two horizontal plates on the front side of the vertical plate. The air tester 3 is located between the two horizontal plates. The upper horizontal plate has a threaded hole 271 that runs vertically through it. A threaded rod 272 is installed in the inner thread of the threaded hole 271. A pressure plate 273 is fixedly installed at the bottom of the threaded rod 272. A rubber pad is fixedly glued to the bottom of the pressure plate 273. The rubber pad is in contact with the upper surface of the air tester 3. A knob 274 is fixedly installed at the top of the threaded rod 272. A data transmission wire 31 is electrically connected to one side of the air tester 3. The other end of the data transmission wire 31 passes through to the rear side of the operation plate 1 and is electrically connected to the signal input terminal of the display panel 4 to realize real-time data transmission and display. When using this air conditioning vent inspection device, the operator first inserts the detection plate 2 into the grille gap of the air conditioning vent. By holding the operating plate 1 and pushing it forward, the detection plate 2 gradually enters the air duct. At this time, the air quality data detected by the air quality tester 3 can be observed in real time through the display panel 4. The air quality tester 3 is a KT01 PM2.5 tester. The device uses infrared technology, and detects the diffuse reflection light intensity of particulate matter through infrared light-emitting diodes and phototransistors installed diagonally in the cavity. It can identify fine particles such as tobacco smoke. The body dimensions are 98×61×22 mm. Measuring 130g in size and compact in shape, this device allows for easy and direct insertion into the air vent for PM2.5 testing of the air conditioning source. The air quality tester 3 is inserted between the two vertical plates of the C-shaped mounting plate 27. A rotating knob 274 drives the threaded rod 272 to rotate, which in turn controls the downward movement of the pressure plate 273 via the threaded connection between the threaded rod 272 and the threaded hole 271. This process securely installs the air quality tester 3 by pressing it firmly with a rubber pad. The tester's position can be changed or adjusted as needed. The data transmission cable 31 transmits the test data to the display panel 4 in real time, allowing maintenance personnel to intuitively understand the internal environmental conditions of the air vent.

[0020] The working principle of this air conditioner vent inspection device will be explained in detail below.

[0021] like Figure 1-5As shown, when using this air conditioning vent inspection device, the operator first inserts the detection plate 2 into the grille gap of the air conditioning vent. By holding the operating plate 1 and pushing it forward, the detection plate 2 gradually enters the air duct. At this time, the air quality data detected by the air quality tester 3 can be observed in real time through the display panel 4. The air quality tester 3 is a KT01 model PM2.5 tester. The device uses infrared technology and detects the diffuse reflection light intensity of particulate matter through infrared light-emitting diodes and phototransistors installed diagonally in the cavity. It can identify fine particles such as tobacco smoke. The device has a body size of 98×61×22mm and a weight of 130g. It is small and flexible, making it convenient to directly enter the air vent for PM2.5 detection of the air conditioning air source. If it is necessary to clean the inner wall of the air duct, the pull ring 231 can be pulled to make it extend. The slide bar 23 moves backward, causing the cleaning cotton strip 236 at its front end to contact the inner wall of the air duct. Due to the elasticity of the elastic plate 235, the cleaning cotton strip 236 can adapt to the inner wall surface with different curvatures, achieving effective wiping. Repeatedly pushing and pulling the slide bar 23 can complete multiple cleanings of the inner wall of the air duct. The cleaning cotton 241 on the air guide plate of the cleaning mounting plate 24 can be used to clean the surface of the air guide plate of the air outlet. The cleaning mounting plate 24 is fixed by the positioning plug 242 and the positioning hole 25, which is convenient for installation and disassembly, and easy to replace or clean the cleaning cotton. The air tester 3 is firmly installed by the C-shaped mounting plate 27 and the threaded clamping structure. The position of the tester can be replaced or adjusted as needed. The data transmission wire 31 transmits the detection data to the display panel 4 in real time, which makes it convenient for maintenance personnel to intuitively understand the internal environmental conditions of the air outlet.
