[0017] In the accompanying drawings, the components represented by the reference numerals are listed as follows:

[0018] 1. Air duct body, 2. Metal dustproof layer. DETAILED DESCRIPTION

[0019] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0020] like Figure 1 As shown, an embodiment of the present application provides an air duct, comprising: an air duct body 1 and a metal dustproof layer 2.

[0021] The air duct body 1 is a plastic part, and the metal dustproof layer 2 is arranged on the inner surface of the air duct body 1, so that the air duct forms an imitation metal air duct.

[0022] The air duct provided in the embodiment of the present application has a metal dustproof layer 2 added to the inner surface of the air duct body 1, so that the air duct forms an imitation metal air duct with the characteristics of high conductivity and high surface finish of metal. Therefore, the high conductivity of the metal can be relied on to weaken the electrostatic effect of dust, and the high surface finish of the metal can be relied on to reduce the contact area with the dust, thereby achieving the purpose of dust prevention, which is beneficial to avoiding the problem of dust adsorption in the air duct causing dirt blockage and bacterial growth, and is beneficial to the health of users.

[0023] In some exemplary embodiments, the metal dustproof layer 2 completely covers the inner surface of the air duct body 1, so that the entire air duct can have a good dustproof effect.

[0024] In other exemplary embodiments, the metal dustproof layer 2 partially covers the inner surface of the air duct body 1. For example, the metal dustproof layer 2 may be provided only in the areas of the air duct that are easy to absorb dust (such as the turning area or the area with convex or concave positions), while the metal dustproof layer 2 is not required to be provided in the areas that are not easy to absorb dust, which is conducive to reducing the production cost of the air duct.

[0025] In some exemplary embodiments, the metal dustproof layer 2 and the air duct body 1 are an integrated structure.

[0026] In other words, the metal dustproof layer 2 is tightly connected to the air duct body 1 and cannot be separated. In this way, the connection strength between the metal dustproof layer 2 and the air duct body 1 is high, and the reliability of use is strong.

[0027] For example, the metal dustproof layer 2 can be prepared on the air duct body 1 by means of thermal spraying, electroplating, vapor deposition, etc., with the air duct as the base.

[0028] In other exemplary embodiments, the metal dustproof layer 2 and the air duct body 1 are a split assembly structure.

[0029] In other words, the metal dust layer 2 and the air duct body 1 are separately formed and then assembled together. When the metal dust layer 2 is prepared separately, a common preparation method of a metal plate or sheet can be used, and the metal dust layer 2 and the air duct body 1 are fixed together by conventional gluing (such as using adhesives, double-sided tape), snaps, fasteners (such as screws), magnetic attraction, thermal bonding, etc., which is conducive to reducing the manufacturing cost of the air duct.

[0030] In some exemplary embodiments, the hardness of the metal dustproof layer 2 is greater than 50 HV. This can prevent the dust from being constantly disturbed in the airflow, resulting in large friction, causing the surface of the metal dustproof layer 2 to be scratched and affecting the surface finish of the metal dustproof layer 2, thereby facilitating the long-term dustproof effect of the metal dustproof layer 2.

[0031] In some exemplary embodiments, the surface finish of the metal dustproof layer 2 is greater than or equal to level 6. This can reduce the friction between the dust and the metal dustproof layer 2, which is conducive to improving the long-term dustproof effect of the metal dustproof layer 2.

[0032] In some exemplary embodiments, the surface resistivity of the metal dustproof layer 2 is less than 100Ω, which facilitates the metal dustproof layer 2 to quickly conduct away static electricity and avoid local accumulation of static electricity, which is conducive to improving the long-term dustproof effect of the metal dustproof layer 2.

[0033] In some exemplary embodiments, the metal dustproof layer 2 is: a pure metal layer, a metal alloy layer or a metal oxide layer.

[0034] In other words, the main component of the metal dustproof layer 2 is metal, but the existence form of the metal is not limited, and the processing method is not limited. It can be pure metal, metal alloy, or metal oxide. In the embodiment of the present application, the pure metal layer, metal alloy layer, and metal oxide layer are all metal dustproof layers 2 prepared using existing materials and existing processes, and do not involve improvements to the material itself and the process itself.

[0035] In some exemplary embodiments, the metal dustproof layer 2 is: a galvanized sheet layer, an aluminum foil layer, a steel sheet layer or an aluminum-magnesium alloy layer.

[0036] Of course, the metal dustproof layer 2 is not limited to the above-mentioned ones, and may also be an alloy layer or an oxide layer including the above-mentioned metals.

[0037] In some exemplary embodiments, the material of the plastic part includes at least one of the following: ABS (terpolymer of acrylonitrile-butadiene-styrene), PS (Polystyrene), AS (acrylonitrile-styrene copolymer), PP (Polypropylene), SAN (styrene-acrylonitrile copolymer). These materials are all existing materials.

[0038] In other words, the plastic part may be ABS plastic, PS plastic, AS plastic, PP plastic, SAN plastic, or an alloy plastic including any of the above plastics.
