It provides a suitable riding environment by regulating the temperature, humidity and air quality inside the carriage. Cleaning the air conditioning ventilation ducts is an important step in ensuring indoor air quality and system efficiency.
[0003] In the existing technology, when cleaning air conditioning ventilation ducts, high-pressure air guns are usually used to initially remove dust from the air conditioning ventilation ducts, and then high-pressure water guns are used to thoroughly clean the ventilation ducts. However, because the ventilation ducts are long, dust will still remain on the duct walls in areas that cannot be washed by high-pressure water guns. This dust adheres to the duct walls, resulting in incomplete cleaning, poor cleaning effect, and poor practicality. Utility Model Content

[0028] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0029] Please refer to the following: Figures 1 to 4 The present invention provides a cleaning device for ventilation ducts used in subway air conditioning systems. The cleaning device includes a telescopic structure 10 and a cleaning structure 20. One end of the telescopic structure 10 extends into the ventilation duct to be cleaned. The cleaning structure 20 is disposed on the extended end of the telescopic structure 10 and has two hinged and expandable sheet-like cleaning parts.
[0030] Two closed, sheet-like cleaning sections are pushed into the ventilation duct to be cleaned by the telescopic structure 10, open at the cleaning position and contact the duct wall, so as to complete the scraping and cleaning of the ventilation duct wall under the pull of the telescopic structure 10.
[0031] Compared with the prior art, the subway air conditioning ventilation duct cleaning device provided in this embodiment is equipped with a telescopic structure 10 that can extend into the ventilation duct to be cleaned. A cleaning structure 20 is provided on the extension end of the telescopic structure 10. The cleaning structure 20 can be pushed into the ventilation duct to be cleaned by two hinged and openable sheet-like cleaning parts when closed, along with the telescopic structure 10. It opens at the cleaning position and contacts the duct wall. Then, with the pulling of the telescopic structure 10, the duct wall of the ventilation duct is scraped and cleaned. It can thoroughly clean the dust attached to the duct wall, and the cleaning is thorough, effective, and practical.
[0032] In some embodiments, the cleaning structure 20 described above may employ, for example... Figures 1 to 4 The structure shown. See also Figures 1 to 4 The cleaning structure 20 includes a hinge plate 21 and a drive structure 22. Two hinge plates 21 are provided, each hinged to the extension end of the telescopic structure 10, and the hinge axes of the hinge plates 21 are collinear. Two drive structures 22 are provided, each corresponding to one of the two hinge plates 21, and each drive structure 22 is used to drive the corresponding hinge plate 21 to pitch and rotate.
[0033] Two hinge plates 21 are hinged to each other and both are hinged to the extension end of the telescopic structure 10. The hinge axes of each hinge plate 21 are collinear. The drive structure 22 can drive the corresponding hinge plate 21 to pitch and rotate.
[0034] In some embodiments, the telescopic structure 10 may adopt the following... Figure 1 , Figure 3 , Figure 4 The structure shown. See also Figure 1 , Figure 3 , Figure 4 The other end of the telescopic structure 10 is provided with a fixing ring 11, which is sleeved on the telescopic structure 10. The fixing ring 11 has multiple through holes that pass through the fixing ring 11 along the telescopic direction of the telescopic structure 10. The multiple through holes are evenly arranged on the fixing ring 11.
[0035] In some embodiments, the driving structure 22 described above may adopt the following... Figure 1 , Figure 3 , Figure 4 The structure shown. See also Figure 1 , Figure 3 , Figure 4 Each drive structure 22 includes two connecting ropes 221. One end of the two connecting ropes 221 is spaced apart on the corresponding hinge plate 21 along the hinge axis of the hinge plate 21, and the other end of the two connecting ropes 221 passes through the through hole.
[0036] Each hinge piece 21 is provided with a connecting unit for connecting the corresponding two connecting ropes 221.
[0037] Two connecting ropes 221 can be spaced apart on the corresponding hinge pieces 21 along the direction of the hinge axis. This can be understood as one end of each connecting rope 221 being connected to the end of the corresponding hinge piece 21 away from its hinge end, which makes it convenient for the connecting ropes 221 to be pulled to open the hinge pieces 21.
[0038] In some embodiments, the connection unit described above may employ, for example... Figure 1 , Figure 2 , Figure 4 The structure shown. See also Figure 1 , Figure 2 , Figure 4 Each connecting unit is a fastening screw 211, which is threadedly connected to the hinge plate 21 and is used to clamp one end of the corresponding connecting rope 221 onto the hinge plate 21.
[0039] The connecting unit is a fastening screw 211, which can be understood as a screw with a threaded connection at the corner of the hinge plate 21, which can clamp one end of the corresponding connecting rope 221 onto the hinge plate 21.
[0040] In some embodiments, the telescopic structure 10 may adopt the following... Figure 1 , Figure 3 , Figure 4 The structure shown. See also Figure 1 , Figure 3 , Figure 4 The telescopic structure 10 includes multiple sleeves 12, which are sequentially fitted together. The innermost sleeve 12 is the insertion end, and the fixing ring 11 is fitted onto the outermost sleeve 12.
[0041] Multiple sleeves 12 are sequentially fitted, allowing adjacent inner sleeves 12 to extend. These multiple sleeves 12 can be understood as multi-segment telescopic sleeves 12, a device whose length can be freely adjusted. Typically composed of multiple sleeves 12, they achieve telescopic movement through a specific mechanism, including an outer tube, an inner tube, and connecting components. The outer tube serves as the outer shell of the entire device, providing support and protection. The inner tube is located inside the outer tube and slides relative to it through a specific connection method, thereby changing the overall length. Connecting components, such as threads or snap-fits, are used to fix or limit the relative position between the inner and outer tubes. Multi-segment telescopic sleeves 12 are existing technology and will not be described in detail here.
[0042] In some embodiments, the sleeve 12 may be adopted as follows: Figure 1 , Figure 3 , Figure 4 The structure shown. See also Figure 1 , Figure 3 , Figure 4 Each sleeve 12 has a larger diameter at one end and a smaller diameter at the other end, which is used to prevent it from detaching from the adjacent outer sleeve 12 when the adjacent inner sleeve 12 extends.
[0043] In some embodiments, the sleeve 12 may be adopted as follows: Figure 1 , Figure 2 The structure shown. See also Figure 1 , Figure 2 The innermost sleeve 12 has a hinge block 121 on its extended end. The hinge block 121 is hinged to two hinge pieces 21, and the hinge axis is collinear with the hinge axis of the two hinge pieces 21.
[0044] The hinge block 121 can be fixed on the protruding end of the innermost sleeve 12, and the two hinge pieces 21 will extend into the ventilation duct as the protruding end of the innermost sleeve 12 extends.
[0045] In some embodiments, the hinge piece 21 may be as follows: Figure 1 , Figure 3 , Figure 4 The structure shown. See also Figure 1 , Figure 3 , Figure 4 Each hinge piece 21 has a cleaning layer on its edge, which is used to abut against the wall of the ventilation duct to be cleaned when the two hinge pieces 21 are opened.
[0046] When the two hinge plates 21 are open, the cleaning layer can come into contact with the wall of the ventilation duct to be cleaned, and scrape off the dust on the wall of the ventilation duct to be cleaned.
[0047] The cleaning layer is made of soft silicone strips, which can scrape off dust from the walls of ventilation ducts.
[0048] In some embodiments, the hinge piece 21 may be as follows: Figure 3 The structure shown. See also Figure 3 Each hinge piece 21 is provided with an adsorption piece 212, which is used to close the two hinge pieces 21.
[0049] The adsorption piece 212 is a magnetic piece that can close the two hinge pieces 21.
[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
