And then the pipeline is clamped and fixed through the iron clamping pieces, so that the redundant part is stored, and the pipeline is prevented from being bent during air exhaust.

Description

Technical Field

[0001] The utility model relates to the technical field of oil smoke air ducts, in particular to an air duct structure for a range hood. Background Art

[0002] The range hood duct is an important component of the range hood, and it has a crucial impact on the exhaust effect and overall performance of the range hood. The range hood duct refers to the channel inside the range hood used to guide and transport oil smoke. Its main function is to effectively collect the oil smoke generated by the stove and exhaust it outdoors through the duct, thereby keeping the kitchen air clean and reducing the harm of oil smoke to human health and pollution to the kitchen environment. However, the currently used range hood duct with telescopic performance needs to be trimmed during installation if it is too long, and then it needs to be connected after trimming. The sealing effect after connection is very poor and prone to air leakage. If it is not trimmed and installed, the excess pipe will swing due to the airflow when the range hood is started, and it is easy to bend, affecting the exhaust effect. To this end, we propose a range hood duct structure. Utility Model Content

[0003] The main purpose of the utility model is to provide an air duct structure for a range hood, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A range hood air duct structure includes a check valve, the upper end of the check valve is connected to an aluminum foil steel wire hose, the upper end of the aluminum foil steel wire hose is connected to a flue joint, and a pipeline storage structure is set up on the upper surface of the check valve around the aluminum foil steel wire hose.

[0006] Preferably, fixing holes are provided on the surfaces of the check valve and the flue joint near the four corners.

[0007] Preferably, the check valve is sealed and connected to the range hood air outlet by screws passing through the fixing hole, and the flue joint is sealed and connected to the public exhaust duct interface by screws passing through the fixing hole.

[0008] Preferably, the pipe storage structure includes a support frame, a neodymium magnet, a limiting slide rail, an iron clip and a slide hole. The upper surface of the support frame is fixedly installed with neodymium magnets near both sides. The front and rear ends of the neodymium magnets are fixedly connected to the limiting slide rail, and the lower surface of the iron clip is provided with slide holes near both sides.

[0009] Preferably, there are two iron clips, and both are slidably mounted on the surfaces of the limiting slide rails in front of and behind the neodymium magnet respectively through sliding holes.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the utility model, the range hood air duct structure can be installed without trimming the air duct pipe, thus ensuring the original good sealing performance of the air duct when it leaves the factory. The excess aluminum foil and steel wire hose can be folded and stored inside the support frame through the pipe storage structure, and then clamped and fixed with iron clips to store the excess part, thereby avoiding bending of the pipe during exhaust.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] like Figure 1-3 As shown, a range hood air duct structure includes a check valve 1, the upper end of the check valve 1 is connected to an aluminum foil steel wire hose 2, the upper end of the aluminum foil steel wire hose 2 is connected to a flue joint 3, and a pipe storage structure 4 is arranged on the upper surface of the check valve 1 around the aluminum foil steel wire hose 2;

[0018] Fixing holes 11 are provided on the surfaces of the check valve 1 and the flue joint 3 near the four corners; the check valve 1 is sealed with the range hood outlet by screws passing through the fixing holes 11, and the flue joint 3 is sealed with the public exhaust duct interface by screws passing through the fixing holes 11; the pipeline storage structure 4 includes a support frame 41, a neodymium magnet 42, a limiting slide rail 43, an iron clip 44 and a sliding hole 45, and the upper surface of the support frame 41 is fixedly installed with neodymium magnets 42 near both sides, and the front and rear ends of the neodymium magnets 42 are fixedly connected to the limiting slide rails 43, and the lower surface of the iron clip 44 is provided with sliding holes 45 near both sides; there are two iron clips 44, and they are slidably installed on the surface of the limiting slide rails 43 in front of and behind the neodymium magnet 42 through the sliding holes 45.

[0019] It should be noted that the utility model is a range hood air duct structure. When in use, the check valve 1 is connected to the smoke outlet of the range hood, and the flue joint 3 is connected to the public exhaust duct port. Then the installer shrinks the excess aluminum foil steel wire hose 2 toward the inside of the support frame 41 for storage. After storage, the two iron clips 44 are slid toward the aluminum foil steel wire hose 2 through the limiting slide rail 43 and clamped in the concave part of the aluminum foil steel wire hose 2. At this time, the neodymium magnet 42 respectively absorbs the front and rear iron clips 44 and fixes them, thereby clamping the excess shrunken aluminum foil steel wire hose 2 in the lower part to the inside of the support frame 41 to complete the installation.
