[0002] As a simple and easy-to-use device, fans are widely used. In daily life, we often use fans to update the air in the house. When in use, the fan needs to use an air outlet duct to transport air to indoors or outdoors. When the fan is needed to input air from the outside to the indoor, a filter structure needs to be installed on the air outlet duct to filter out dust and lint in the air through the filter to improve the quality of the air input to the room. The filter structure needs to be cleaned regularly to ensure its filtering effect, but in the existing air outlet duct assembly structure, it is not convenient to disassemble and install the filter.

[0009] Preferably, the bracket includes limit frames arranged on both sides of the filter frame, and the cross-section of the limit frames is concave.

[0010] Preferably, the filter frame is in a square frame shape, and limiting columns are provided at the four corners.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] The utility model provides a first notch and a second notch so that the bracket can enter and exit the ventilation pipe body. Since the support rod is slidably connected to the sliding groove, the bracket can move along the sliding groove, or enter and exit the ventilation pipe body along the sliding groove, and the bracket is pressed by the pressing block so that it cannot move along the sliding groove, so as to achieve the purpose of fixing the bracket. The bracket of the utility model is easy to pull out and fix, and the filter frame is inserted into the bracket for easy removal and loading. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an air outlet duct assembly of a ventilator, in order to facilitate the disassembly and assembly of the filter screen for cleaning, the utility model includes a ventilation duct body 1 and a filtering mechanism, the ventilation duct body 1 has a cross-section in the shape of a square, and the ventilation duct body 1 is respectively provided with a first notch 11 and a second notch 12 on two adjacent side surfaces, the first notch 11 is communicated with the second notch 12, the filtering mechanism includes a bracket 2 that can pass through the first notch 11 and the second notch 12, a filter screen frame 3 is inserted in the bracket 2, the bracket 2 includes a support rod arranged outside the ventilation duct body 1, the filtering mechanism also includes a first limiting unit 4 and a second limiting unit 5 for positioning the bracket 2 in the ventilation duct body 1, the first limiting unit 4 includes two limiting plates 41, the limiting plate 41 is provided with a sliding groove 42, the support rod is slidably connected to the sliding groove 42, and the second limiting unit 5 includes a pressing block 51 for pressing the bracket 2.

[0022] Specifically, the utility model provides the first notch 11 and the second notch 12 so that the bracket 2 can enter and exit the ventilation duct body 1. Since the support rod is slidably connected to the sliding groove 42, the bracket 2 can move along the sliding groove 42, or can enter and exit the ventilation duct body 1 along the sliding groove 42, and the bracket 2 is pressed by the pressing block 51 so that it cannot move along the sliding groove 42, so as to achieve the purpose of fixing the bracket 2. The bracket 2 of the utility model is convenient to be pulled out and fixed, and the filter frame 3 is inserted into the bracket 2, which is convenient to take out and load.

[0023] Furthermore, two limiting plates 41 are disposed below the first notch 11 , the two limiting plates 41 are disposed on both sides of the first notch 11 , and the support rod is disposed between the two limiting plates 41 .

[0024] Furthermore, the cross section of the sliding groove 42 is L-shaped. Specifically, when the support rod moves to the end of the sliding groove 42 away from the ventilation pipe body 1, the bracket 2 has enough space for movement, so that the bracket 2 can rotate.
