[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention aims to solve the problems that there is usually no positioning structure between air ducts. During the installation and fixing process, it is difficult to accurately find the proper position of the air duct without positioning, which increases the installation difficulty, is prone to deviation during the installation process, and it is difficult to ensure the installation accuracy. Moreover, when the inside of the air duct needs to be cleaned, other tools are required to clean the inside of the air duct, which is not convenient for cleaning. It provides a Figures 1 - 4 quick-connect type air duct based on modular design as shown in the figure, including a first air duct 1 and a second air duct 11. Connecting plates 23 are provided at one end of the first air duct 1 far from the second air duct 11 and at one end of the second air duct 11 close to the first air duct 1. A clamping block 24 is fixedly connected to one end of the two connecting plates 23 close to each other. The cross-section of the clamping block 24 is a right trapezoid. The second air duct 11 is connected to the inner wall of the first air duct 1 through two clamping blocks 24. The air duct is composed of a plurality of first air ducts 1 and second air ducts 11. When the first air duct 1 and the second air duct 11 are installed, they are connected in sequence at the head and tail. The clamping block 24 on the second air duct 11 is inserted into the inner wall of the first air duct 1. Through the clamping block 24, the proper positions of the first air duct 1 and the second air duct 11 can be accurately found, realizing quick positioning connection, reducing the installation difficulty, not being prone to deviation, ensuring the installation accuracy, and being convenient and fast to install.

[0025] In the present invention, moving plates 32 are slidably arranged on the top and bottom surfaces of the outer walls of the first air duct 1 and the second air duct 11. A second connecting rod 33 is fixedly connected to the side wall of the moving plate 32. The second connecting rod 33 passes through the corresponding first fixing plate 2 and is fixedly connected to the connecting plate 23. The second fixing plate 21 is located between the first fixing plate 2 and the second fixing plate 21. When cleaning the air duct, the cooperation between the second connecting rod 33 and the moving plate 32 can prevent the annular plate 3 from falling off from the inside of the first air duct 1 and the second air duct 11, and the annular plate 3 can also be moved by pushing the moving plate 32, which is convenient for the staff to use.

[0026] It should be noted that a hole is provided in the middle of the second fixing plate 21, and the free end of the second connecting rod 33 passes through the hole of the second fixing plate 21, so as to realize further positioning.

[0027] It should also be noted that a slot 22 is formed on the side wall of the first fixing plate 2, and the connecting plate 23 is inserted into the slot 22. When installing the air duct, the connecting plate 23 is inserted into the slot 22, so that the first fixing plate 2 and the second fixing plate 21 are more closely attached.

[0028] In the present utility model, a first connecting rod 31 is fixedly connected to one side of the right-angle side of the clamping block 24, and an annular plate 3 is fixedly connected to the end of the first connecting rod 31. The two annular plates 3 are respectively slidably connected inside the first air duct 1 and the second air duct 11, and the annular plate 3 is in the shape of a funnel. When cleaning the inside of the air duct, due to the modular design, the first air duct 1 and the second air duct 11 can be respectively removed from the entire air duct. During cleaning, the clamping block 24 is pulled, the movement of the clamping block 24 drives the movement of the first connecting rod 31, and the movement of the first connecting rod 31 drives the movement of the annular plate 3. The annular plate 3 scrapes off the dust on the inner walls of the first air duct 1 and the second air duct 11. Without using other tools, the dust inside the air duct can be cleaned, which is convenient and fast.

[0029] It should be noted that the first air duct 1 and the second air duct 11 are installed in the direction of air flow. The wide part of the annular plate 3 is the air inlet direction. During use, the air flows towards the narrow part of the annular plate 3, which can enhance the air flow speed in each section of the first air duct 1 and the second air duct 11, thereby avoiding the adhesion of stubborn dust on the inner walls of the first air duct 1 and the second air duct 11, and making the subsequent cleaning more labor-saving.

[0030] Furthermore, the outer walls of the two annular plates 3 are respectively in close contact with the inner walls of the first air duct 1 and the second air duct 11. During cleaning, the dust on the inner walls of the first air duct 1 and the second air duct 11 can be better scraped off, improving the cleaning efficiency.

[0031] In the present utility model, a first fixing plate 2 is fixedly connected to one end of the first air duct 1 and the second air duct 11, and a second fixing plate 21 is fixedly connected to the other end of the first air duct 1 and the second air duct 11. The second fixing plate 21 on the first air duct 1 and the first fixing plate 2 on the second air duct 11 are connected by bolts. The first fixing plate 2 and the second fixing plate 21 are fixedly installed by bolts, making the installation of the first air duct 1 and the second air duct 11 more firm.
