Description

Technical Field

[0001] This utility model relates to the field of air conditioning air supply system technology, and in particular to an automotive air conditioning duct structure. Background Technology

[0002] An automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air inside a vehicle. A modern air conditioning system consists of a refrigeration system, a heating system, ventilation and air purification devices, and a control system. The duct structure in an automotive air conditioning system refers to a pipe system composed of copper or aluminum pipes and high-pressure rubber hoses. Through these pipes, the various components of the automotive air conditioning system are connected to form a closed system.

[0003] As the usage time increases, an odor may be detected from the air outlet of the air conditioning system's duct structure. This is usually due to condensate remaining in the pipes combining with airborne microorganisms to produce an odor. Additionally, smoke, dust, and exhaust gases from the outside air enter the duct through the air intake channel. These pollutants and odors are discharged from the air outlet through the duct structure after the air conditioning system is started. Therefore, in order to reduce the discharge of such pollutants, dust and odor removal filters are usually installed in the duct.

[0004] In related technologies, one can refer to the Chinese utility model patent with authorization announcement number CN217319977U, which discloses a dual-zone air conditioning duct structure for automobiles, including a main air duct and a side air duct, with a wind speed regulating cylinder between the main air duct and the side air duct, a filter plate inside the main air duct, and multiple activated carbon mesh plates inside the side air duct.

[0005] Airflow originates from the main duct, passes through the fan speed regulating cylinder, and exits through two side ducts. The filter plate in the main duct filters the air, while the activated carbon plate in the side ducts purifies it. When cleaning or replacing the filter plate and activated carbon plate, the main duct, side ducts, and fan speed regulating cylinder must all be disassembled. Then, the filter plate in the main duct and the activated carbon plate in the side duct must be disassembled sequentially. Because the side duct is relatively long, disassembling the activated carbon plate is quite troublesome, which increases the cleaning time of the main duct and side ducts, thus reducing the convenience of cleaning the car's air conditioning ducts. Utility Model Content

[0006] To improve the ease of cleaning automotive air conditioning ducts, this utility model provides an automotive air conditioning duct structure.

[0007] The automotive air conditioning duct structure provided in this application adopts the following technical solution:

[0008] An automotive air conditioning duct structure includes a main air duct and side air ducts disposed on the main air duct. The main air duct is used to connect to an air conditioning outlet. Both ends of the side air ducts are connected to air outlet pipes. The main air duct and the side air ducts are detachably connected by a connecting pipe. The connecting pipe is provided with a purification component for purifying the gas.

[0009] By adopting the above technical solution, the gas flows from the air conditioning outlet through the main air duct and connecting pipe to the side air duct. The purification component removes dust and purifies the airflow. The purified gas then escapes into the vehicle interior through the air outlet pipe after passing through the side air duct. During cleaning, only the connecting pipe needs to be disassembled for cleaning or replacement, without the need to disassemble the entire air duct structure. This saves time in cleaning the car air conditioning duct and improves the convenience of cleaning the car air conditioning duct.

[0010] Optionally, the side air duct is provided with a connector, and the two ends of the connector are respectively connected to the main air duct and the connector. The side air duct is provided with a diverter plate, which extends into the connector and divides the space in the connector and the side air duct into a first chamber and a second chamber that are symmetrically arranged on the left and right. The first chamber and the second chamber are respectively connected to two air outlet pipes.

[0011] By adopting the above technical solution, the gas is diverted by the diverter plate after passing through the main air duct and the connector. Part of the diverted gas escapes from the corresponding air outlet pipe after passing through the first chamber, and the other part escapes from the other air outlet pipe after passing through the second chamber. The diverter plate improves the uniformity of gas distribution, thereby enabling multiple side air ducts to work through one main air duct, which simplifies the duct layout and improves the convenience of cleaning the automotive air conditioning duct.

[0012] Optionally, the two ends of the connecting pipe are respectively inserted into the main air duct and the connector and are tightly fitted with the main air duct and the connector, and the two ends of the connecting pipe are provided with sealing rings.

[0013] By adopting the above technical solutions, the direct-insertion design improves the convenience of installing and disassembling the connecting pipe, while the sealing ring improves the sealing performance of the connection between the connecting pipe and the main air duct and the connector.

[0014] Optionally, the purification component includes:

[0015] A dustproof filter plate, wherein the dustproof filter plate is disposed inside the connecting pipe;

[0016] An activated carbon plate is disposed inside a connecting pipe and spaced apart from a dust filter plate, with the activated carbon plate located between the dust filter plate and the connector.

[0017] By adopting the above technical solution, the dust filter plate removes dust from the air discharged from the air conditioning vent. The dust-removed air is then purified by the activated carbon plate before passing through the connector and side air duct in sequence and being discharged into the vehicle interior through the air outlet pipe. The dust filter plate and activated carbon plate work together to improve the air conditioning air purification effect. During cleaning, simply move the connecting pipe away from the main air duct and the connector, and then clean the dust filter plate and activated carbon plate inside the connecting pipe. Then, reinstall the new or cleaned connecting pipe between the main air duct and the connector. This improves the convenience of cleaning the car air conditioning duct and enhances the air conditioning air purification effect.

[0018] Optionally, the dust filter plate is detachably disposed in the connecting pipe via a first connecting assembly, and the activated carbon plate is detachably disposed in the connecting pipe via a second connecting assembly.

[0019] By adopting the above technical solution, after removing the connecting tube, the dust filter plate and activated carbon plate can be disassembled, cleaned, or replaced by opening the first connecting component and the second connecting component respectively, without having to replace the entire connecting tube, thereby reducing the consumption of parts and thus reducing costs.

[0020] Optionally, the first connection component includes:

[0021] Internal thread, wherein the internal thread is provided inside the connecting pipe;

[0022] External thread, which is provided on the dust filter plate and mates with the internal thread.

[0023] By adopting the above technical solution, the dust filter plate is placed inside the connecting pipe, and then the dust filter plate is rotated so that the external thread and the internal thread are connected together through thread engagement. Disassembly can be performed by rotating in the opposite direction, thereby improving the convenience of dust filter plate disassembly and assembly, and thus improving the convenience of cleaning the car air conditioning duct.

[0024] Optionally, the outer surface of the activated carbon plate has a mounting groove, the inner surface of the connecting pipe has a positioning groove, and the second connecting assembly includes:

[0025] A connecting spring, wherein the connecting spring is disposed in a mounting groove;

[0026] A connecting post is located at the end of the connecting spring away from the inner wall of the mounting groove. During installation, the connecting post is inserted into the positioning groove to position the activated carbon plate.

[0027] By adopting the above technical solution, the connecting column is pressed to squeeze the connecting spring into the installation groove, the activated carbon plate is placed in the connecting tube, and then the activated carbon plate is pushed to the positioning groove. The connecting spring returns to its deformation and drives the connecting column to be inserted into the positioning groove to position the activated carbon plate. When disassembling, the activated carbon plate is pulled or pushed to drive the connecting spring to pull the positioning column out of the positioning groove, and then the activated carbon plate can be directly pulled out of the connecting tube. This realizes the installation, positioning, disassembly and replacement of the activated carbon plate, thereby improving the convenience of installing and removing the activated carbon plate, and thus improving the convenience of cleaning the automotive air conditioning duct.

[0028] Optionally, both the dust filter plate and the activated carbon plate are provided with cross grooves to facilitate the connection of external disassembly tools.

[0029] By adopting the above technical solution, the cross groove facilitates the connection of external tools that can be used for leverage, thereby improving the ease of disassembly and assembly of activated carbon plates and dust filter plates.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Gas flows from the air conditioning outlet through the main air duct and connecting pipe to the side air duct. The purification component removes dust and purifies the air. The purified gas then escapes into the vehicle interior through the air outlet pipe after passing through the side air duct. During cleaning, only the connecting pipe needs to be disassembled for cleaning or replacement. There is no need to disassemble the entire air duct structure, which saves time in cleaning the car air conditioning duct and thus improves the convenience of cleaning the car air conditioning duct.

[0032] 2. The dust filter removes dust from the air vents. The dust-removed air is then purified by the activated carbon plate before passing through the connector and side duct and finally being discharged into the vehicle's interior through the exhaust pipe. The dust filter and activated carbon plate work together to improve the air purification effect. To clean, simply detach the connecting pipe from the main duct and connector, then clean the dust filter and activated carbon plate inside the connecting pipe. Reinstall the new or cleaned connecting pipe between the main duct and connector. This improves the convenience of cleaning the car's air conditioning ducts and enhances the air purification effect.

A sealing ring 321 is fixed on the outer surface of the insertion part 32.

[0045] Reference Figure 2 and Figure 4 The purification component 4 includes a dust filter plate 41 and an activated carbon plate 42. The dust filter plate 41 is circular and has multiple filter holes (not shown in the figure) for filtering dust. The dust filter plate 41 is detachably installed in the connecting pipe 3 through the first connecting component 6.

[0046] Reference Figure 2 , Figure 4 and Figure 5 The first connecting component 6 includes an internal thread 61 and an external thread 62. The internal thread 61 is located inside the connecting part 31, and the external thread 62 is located on the outer surface of the dust filter plate 41 and mates with the internal thread 61. A cross groove 63 is provided at the center of the dust filter plate 41 to facilitate the connection of external disassembly tools. During installation, the dust filter plate 41 is rotated so that the external thread 62 and the internal thread 61 are connected together by the thread. During disassembly, the external thread 62 is rotated in the opposite direction, thereby improving the ease of disassembly and assembly of the dust filter plate 41.

[0047] Reference Figure 2 and Figure 5The activated carbon plate 42 is disposed inside the connecting pipe 3 and spaced apart from the dust filter plate 41. The activated carbon plate 42 is located between the dust filter plate 41 and the connector 22. The activated carbon plate 42 has multiple vent holes (not shown in the figure) for gas to pass through. The activated carbon plate 42 is detachably disposed inside the connecting pipe 3 through the second connecting assembly 7. Four mounting grooves 421 are symmetrically opened on the outer surface of the activated carbon plate 42. The connecting part 31 has four positioning grooves 311. The second connecting assembly 7 has four grooves, which correspond one-to-one with the positioning grooves 311 and the mounting grooves 421.

[0048] Reference Figure 2 and Figure 5 The following description focuses on the second connecting component 7. The second connecting component 7 includes a connecting spring 71 and a connecting post 72. The connecting spring 71 is fixed to the inner wall of the corresponding mounting groove 421 and extends horizontally. The connecting post 72 is fixed to the end of the connecting spring 71 away from the inner wall of the mounting groove 421 and extends horizontally. When the connecting post 72 is pressed to squeeze the connecting spring 71, the connecting post 72 can retract into the mounting groove 421. During installation, the connecting post 72 is inserted into the positioning groove 311 to position the activated carbon plate 42. The center of the activated carbon plate 42 is also provided with a cross groove 63 for easy access to external disassembly tools.

[0049] Reference Figure 2 , Figure 4 and Figure 5 During installation, first press the connecting post 72 back into the mounting groove 421, then place the activated carbon plate 42 into the connecting part 31, push the activated carbon plate 42 to the positioning groove 311 with a tool, rotate the activated carbon plate 42 to make the connecting post 72 pop out and insert into the positioning groove 311, then rotate the dust filter plate 41 to make the internal thread 61 and the external thread 62 mate, then insert one end of the connecting tube 3 into the main air duct 1 or the connector 22, tap the connecting tube 3 to make it fit tightly and then connect the other end, and finally install the entire air duct structure into the frame.

[0050] Reference Figure 1 , Figure 2 and Figure 3 The dust filter plate 41 removes dust from the air discharged from the air conditioning outlet. The air after dust removal is then purified by the activated carbon plate 42 before flowing through the connector 22 into the side air duct 2 and the branch air duct 5. Finally, it is discharged into the vehicle interior through the air outlet duct 21. The dust filter plate 41 and the activated carbon plate 42 work together to improve the air purification effect of the air conditioning gas, eliminating the need to install air purification components in the side air duct 2.

[0051] Reference Figure 2 and Figure 3During disassembly, the side air duct 2 and branch air duct 5 are removed from the vehicle frame. Then, the connector 22 is disengaged from the connecting pipe 3. Next, the connecting pipe 3 is disengaged from the main air duct 1. Then, the dust filter plate 41 and activated carbon plate 42 inside the connecting pipe 3 can be replaced as needed. After cleaning, the new connecting pipe 3 or the cleaned connecting pipe 3 can be reinstalled between the main air duct 1 and the connector 22. Therefore, during cleaning, only the connecting pipe 3 needs to be disassembled for cleaning or replacement. There is no need to disassemble the entire air duct structure, which saves time in cleaning the car air conditioning air duct and improves the convenience of cleaning the car air conditioning air duct.

[0052] The working principle of this application embodiment is as follows:

[0053] The dust filter plate 41 removes dust from the air discharged from the air conditioning outlet. The air after dust removal is then purified by the activated carbon plate 42 before flowing through the connector 22 into the side air duct 2 and the branch air duct 5. Finally, it is discharged into the vehicle interior through the air outlet duct 21. The dust filter plate 41 and the activated carbon plate 42 work together to improve the air conditioning air purification effect, eliminating the need to install air purification components in the side air duct 2.

[0054] During disassembly, the side air duct 2 and branch air duct 5 are removed from the vehicle frame. Then, the connector 22 is disengaged from the connecting pipe 3. Next, the connecting pipe 3 is disengaged from the main air duct 1. Then, the dust filter plate 41 and activated carbon plate 42 inside the connecting pipe 3 can be replaced as needed. After cleaning, the new connecting pipe 3 or the cleaned connecting pipe 3 can be reinstalled between the main air duct 1 and the connector 22. Therefore, during cleaning, only the connecting pipe 3 needs to be disassembled for cleaning or replacement. There is no need to disassemble the entire air duct structure, which saves time in cleaning the car air conditioning air duct and improves the convenience of cleaning the car air conditioning air duct.
