[0027] Figures 1-7 Schematic diagram of a blow gun nozzle with an adjustable air outlet 101 according to an embodiment of the present utility model. Refer to Figure 1, the air gun nozzle with an adjustable air outlet 101 includes a main body 1, a plurality of windshields 2 and an adjusting circular plate 3. First, an annular wall surface 102 is provided on the main body 1, and an air outlet 101 is formed at the central position of the annular wall surface 102. At the same time, a plurality of assembly holes 103 are provided at equal intervals near the air outlet 101. A plurality of windshields 2 are also provided on the annular wall surface 102, and a first assembly post 201 and a second assembly post 202 are provided on each windshield 2. Moreover, as a preferred embodiment, refer to Figure 2 The first assembly post 201 is provided on the upper surface of the windshield 2, and the second assembly post 202 is provided on the lower surface of the windshield 2 and is staggered with the first assembly post 201. Among them, each first assembly post 201 is respectively combined and installed with the assembly hole 103 individually, that is, a first assembly post 201 is installed on each assembly hole 103 so that the windshield 2 is rotationally installed on the annular wall surface 102 with the assembly hole 103 as the axis. Then, an adjusting circular plate 3 is further covered on the plurality of windshields 2. A plurality of limiting holes 301 are provided on the adjusting circular plate 3. Then, each limiting hole 301 is respectively combined and installed with the second assembly post 202 individually, that is, a second assembly post 202 is installed on each limiting hole 301 so that the adjusting circular plate 3 is combined and installed on the plurality of windshields 2. Further, the second assembly post 202 can also slide in the limiting hole 301. When the adjusting circular plate 3 rotates, it drives the windshield 2 to rotate, so that the windshield 2 rotates with the assembly hole 103 as the axis under the drive of the adjusting circular plate 3 to block or expose the air outlet 101. Specifically, when the windshield 2 rotates around the assembly hole 103 towards the center of the air outlet 101, since the windshield 2 will gradually gather towards the center of the air outlet 101 and gradually block the air outlet 101, the air outlet area of the air outlet 101 will become smaller and smaller during this process, realizing the control of the air volume from large to small. On the other hand, when the windshield 2 rotates around the assembly hole 103 away from the center of the air outlet 101, since the windshield 2 will gradually move away from the center of the air outlet 101 and gradually expose the air outlet 101, the air outlet area of the air outlet 101 will become larger and larger during this process to realize the control of the air volume from small to large. Among them, refer to Figure 3 and Figure 4 When the end of the windshield 2 far from the second assembly post 202 abuts against the side wall of the main body 1 close to the annular wall surface 102, the exposed range of the air outlet 101 is the largest. In this way, the air outlet area of the air outlet 101 can be flexibly adjusted, so that when repairing different types and sizes of components, there is no need to replace the nozzle of the hot air gun, the operation is fast and convenient, and the deficiencies in the background technology are well solved, improving the efficiency. Secondly, an air inlet communicating with the air outlet 101 is further provided at the bottom of the main body 1, and the air inlet is disposed opposite to the air outlet 101.

[0028] Next, refer to Figure 1 and Figure 6 In order to facilitate the rotation of the adjusting circular plate 3, a toggle piece 302 is provided on one end of the adjusting circular plate 3, and a toggle groove 4 is provided on the outer wall of the main body 1. When the adjusting circular plate 3 is covered on the windshield 2, the toggle piece 302 will be movably installed in the toggle groove 4. When the toggle piece 302 moves in the toggle groove 4, it drives the adjusting circular plate 3 to rotate, and the windshield 2 is driven by the adjusting circular plate 3 to block or reveal the air outlet 101. In other words, when in use, the rotation amplitude of the adjusting circular plate 3 is controlled by toggling the toggle piece 302, so that the multiple windshields 2 are gradually moved away from or close to the center of the air outlet 101 to change the air outlet area of the air outlet 101. Among them, when the windshield 2 moves, two adjacent windshields 2 overlap each other, and the windshield 2 blocks or reveals the air outlet 101 by using multiple windshields 2 stacked together. For example, refer to Figure 7 When the air outlet 101 needs to be shielded, most of the positions of the adjacent wind shields 2 will overlap with each other, and the overlapping area is relatively large; Figure 4 and Figure 6 When the air outlet 101 needs to be exposed, a small portion of the adjacent wind shields 2 will overlap each other, and the overlapping area is small. In addition, the rotation of each wind shield 2 is synchronous, so that the area exposed at the air outlet 101 is centered on the air outlet 101, ensuring that the air nozzle is close to the center of the air outlet 101 to reduce the impact of uneven air discharge on subsequent component processing.

[0029] Further, as a preferred embodiment, in order to make the air volume control of the air outlet 101 more accurate, it can be achieved by increasing the number of wind shields 2. Figure 4 and Figure 5 There can be six wind shields 2 and six limiting holes 301. The six wind shields 2 are each provided with a second assembly column 202 and are slidably installed on the adjusting circular plate 3 through the second assembly column 202. The second assembly column 202 slides in the limiting holes 301 of the adjusting circular plate 3 so that the wind shields 2 are driven to rotate when the adjusting circular plate 3 rotates, thereby realizing the control of the six wind shields 2 by the adjusting circular plate 3.

[0030] Next, refer to Figure 1 , Figure 6 and Figure 7In order to place the windshield 2 in the main body 1, there is an upper cover 5 above the annular wall surface 102, and the upper cover 5 is covered on the main body 1 to form a receiving cavity 6, and the receiving cavity 6 is used to place the windshield 2. There are many ways to install the upper cover 5 on the main body 1. For example, the upper cover 5 can be embedded in the main body 1; or the upper cover 5 can be rotatably installed on the main body 1 by providing mutually matching thread structures on both the main body 1 and the upper cover 5.

[0031] Then, in order to realize the movement of the second assembly column 202 in the limiting hole 301, refer to Figure 1 The limiting hole 301 may be formed by a symmetrically arranged arc-shaped first inner wall 3011 and two long strip-shaped second inner walls 3012, wherein the second inner wall 3012 is connected between the two first inner walls 3011 to form a sliding area for the second assembly column 202. The width between the two second inner walls 3012 is larger than the width of the second assembly column 202, so that the second assembly column 202 can move more smoothly in the limiting hole 301.

[0032] In addition, in order to prevent the adjusting circular plate 3 from blocking the air outlet 101, refer to Figure 1 The adjusting circular plate 3 may be circular and have an opening 303 with the same area as the air outlet 101 at the center, so that the position of the opening 303 is opposite to the air outlet 101 to avoid the adjusting circular plate 3 affecting the air outlet 101 when rotating.

[0033] It should be noted that the air gun nozzle of the adjustable air outlet 101 is installed on the hot air gun when in use. When it is necessary to heat a larger component, refer to Figure 5 The toggle plate 302 needs to be toggled counterclockwise to gradually reduce the shielding of the wind shield 2 on the air outlet 101, thereby increasing the amount of hot air outflow and achieving heating of larger components. When it is necessary to heat smaller components, refer to Figure 7 It is necessary to turn the toggle plate 302 in a clockwise direction to gradually increase the shielding of the wind shield plate 2 on the air outlet 101, thereby reducing the output of hot air and achieving heating treatment for components with smaller sizes.

[0034] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
