[0026] As Figures 1-4As shown, the present application relates to a portable air duct cleaning structure. The portable air duct cleaning structure comprises: an air duct main body 1; the air duct main body 1 refers to a channel for air circulation and circulation, which can achieve the effect of interacting with the outside air. The fixing part 2 is connected to the bottom of the air duct main body 1; by means including but not limited to: pre-embedded installation, bolt connection, it can achieve good fixing and supporting effects, and at the same time achieve the effect of installing other components. Furthermore, the fixing part 2 is a roof profile. Profiles include but are not limited to: aluminum profiles. It can well support and assemble other components.

[0027] Connector 3 is connected to the fixing member 2 on the side away from the duct body 1 and is located between adjacent duct bodies 1. The provision of connector 3 enables effective component connection, thereby achieving effective coordination between various components. Furthermore, connector 3 is a hollow mounting profile with hooks 31 on either side of its bottom. Bolting and utilizing this hollow mounting profile reduces weight and facilitates the installation of other components.

[0028] At least one integrated top plate 4 is snap-fitted to the connecting member 3; by adopting a snap-fit connection method, a good connection effect between the integrated top plate 4 and the connecting member 3 can be achieved, and the integrated top plate 4 can also be directionally rotated, thereby providing a good protection effect for disassembly and assembly. The static pressure chamber 5 is detachably connected to the air duct main body 1, and the bottom is arranged against the integrated top plate 4; by adopting a bolt and nut connection method, a good disassembly effect between the static pressure chamber 5 and the air duct main body 1 can be achieved, thereby achieving the effect of facilitating the removal of the static pressure chamber 5 from the air duct main body 1, and further achieving the effect of facilitating the cleaning of the air duct. At least one locking member 6 is fixedly provided on the fixing member 2 and connected to the end of the integrated top plate 4 away from the connecting member 3; by fixing the locking member 6 on the fixing member 2, a good locking effect can be achieved, thereby ensuring a stable installation effect.

[0029] The movably engaged connection between the connector 3 and the integrated top plate 4, and the abutment between the integrated top plate 4 and the static pressure chamber 5, facilitates disassembly, assembly, and cleaning of the air duct body 1. The movably engaged connection between the connector 3 and the integrated top plate 4 achieves a good blocking and releasing effect, thereby securing and removing the static pressure chamber 5. Simultaneously, the abutment between the integrated top plate 4 and the static pressure chamber 5 effectively secures and supports the static pressure chamber 5, further enhancing structural stability.

[0030] From the above description, it can be seen that this application achieves the following technical effects:

[0031] In the embodiment of the present application, a portable disassembly and assembly method is adopted. The air duct main body 1 is movably clamped with the integrated top plate 4 through the connecting member 3, and the integrated top plate 4 is abutted against the static pressure chamber 5, so that the air duct main body 1 is convenient for disassembly, assembly and cleaning, achieving the purpose of being easy to install and disassemble, thus realizing the technical effects of simplifying the structure, facilitating the cleaning of the air duct and improving the cleaning efficiency, and further solving the technical problems existing in the existing cleaning methods, such as large workload, long time consumption and low efficiency for disassembly and assembly; and due to the complex internal structure of the air duct, the number and size of inspection openings are limited, there are many blind areas, and it is difficult to meet the requirements of comprehensive cleaning.

[0032] Further, an opening 11 is provided on the air duct main body 1, and the opening 11 is connected to the static pressure chamber 5. By providing the opening 11, a good air circulation effect can be achieved, and at the same time, the effect of facilitating the cleaning of the air duct can also be achieved. Furthermore, a first embedded rivet nut 12 perpendicular to the air duct main body 1 and a second embedded rivet nut 13 parallel to the air duct main body 1 through a gasket are respectively provided on both sides of the opening 11. By respectively providing the first embedded rivet nut 12 and the second embedded rivet nut 13 on both sides close to the opening 11, a good pre-installation effect can be achieved, thus realizing the effect of being convenient for subsequent assembly with other components, and further realizing the effects of being easy to disassemble and assemble and saving time. At the same time, by fixedly connecting the gasket with the embedded rivet nut, the effect of being convenient for fixing and changing the direction of the nut can be achieved, thus realizing a good matching effect with other components.

[0033] Further, the integrated top plate 4 includes an inner installed top plate 41 with one end clamped with the hook 31 and a diffuser 42 provided at the other end. By providing the inner installed top plate 41 and the diffuser 42, good decoration and air diffusion effects can be achieved; at the same time, the method of integrating the inner installed top plate 41 and the heat diffuser can achieve the effect of saving assembly time, thus realizing the effect of improving the disassembly and assembly efficiency. The integration method can be a bolt connection or a welding method, which can achieve a good fixed connection effect, thus ensuring a stable connection effect. Furthermore, the inner installed top plate 41 adopts a split design method. The effect of being convenient for disassembly and assembly can be achieved.

[0034] Further, the static pressure chamber 5 includes: a polygonal cavity 51 formed by enclosing with aluminum plates, an extension plate 52 is arranged on one side of the cavity 51, a U-shaped support frame 53 is arranged at the bottom of the extension plate 52 and at the adjacent junction with the cavity 51, a first bolt 54 is vertically arranged at the end of the U-shaped support frame 53, and a second bolt 55 is vertically arranged on the side of the cavity 51 away from the U-shaped support frame 53. By enclosing with aluminum profiles to form the polygonal cavity 51, the effects of easy implementation and convenient operation can be achieved. At the same time, an extension plate 52 is arranged on one side of the cavity 51, which can achieve the effect of matching with the opening 11, so as to achieve the effect of tight connection. And a first bolt 54 and a second bolt 55 are respectively arranged on both sides of the cavity 51, which can achieve the effect of matching with other components, so as to achieve the effect of fixedly connecting the static pressure chamber 5 with the air duct main body 1. Further, the first bolt 54 is in threaded connection with the first embedded rivet nut 12, and the second bolt 55 is in threaded connection with the second embedded rivet nut 13. Good threaded connection effects can be achieved, so as to achieve the effect of firmly connecting the static pressure chamber 5.

[0035] Further, the bottom of the cavity 51 is press-connected with the diffuser 42 through a sealing strip. By adopting the sealing strip, the sealing performance can be improved.

[0036] Further, a fastener 7 is arranged at one end of the fixing member 2, and the fastener 7 is connected with the locking member 6. By arranging the fastener 7, good fastening effects can be achieved. Further, the end of the diffuser 42 is located above the fastener 7. The effect of further improving the locking degree can be achieved, so as to prevent the integrated top plate 4 from falling off, and further avoid the situation of personal injury.

[0037] The working principle of the present invention is as follows:

[0038] The whole vehicle air duct does not need to be provided with a separate inspection port. When the inside of the air duct needs to be cleaned, loosen the fasteners 7 on both sides, open the integrated top plate 4 to expose the bottom of the air duct, remove the bolts, and remove the static pressure chamber 5 from the air duct main body 1. After removing the structure of the static pressure chamber 5, the opening 11 of the air duct main body 1 meets the requirements of comprehensive internal cleaning. After the static pressure chamber 5 is wiped and cleaned under the vehicle, restore the static pressure chamber 5 and the interior top structure.

[0039] The present invention also has the following beneficial effects:

[0040] 1. Before opening the inspection port for cleaning, it is necessary to disassemble and remove the air outlet diffuser, interior top plate, and interior ventilation opening and their fasteners of the whole vehicle in sequence, and then open the air duct inspection port. The steps are cumbersome, the procedures are complex, and the workload is huge;

[0041] 2. When there is a maintenance opening set locally in the vehicle's air duct, it is impossible to clean all air ducts, and the inner surface of the partition in the static pressure chamber cannot be cleaned, resulting in cleaning blind spots.

[0042] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the protection scope of the present invention.
