[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figures 1 to 5The illustration shows an easy-to-install exhaust fan, comprising a fixed plate 1, an exhaust assembly 3, and a movable plate assembly 2 that can move along the fixed plate 1. The fixed plate 1 has an installation port 11 and a first adjustment part 12. The exhaust assembly 3 is installed on the installation port 11. The movable plate assembly 2 has a locking member 21, which cooperates with the first adjustment part 12 to lock or unlock the movable plate assembly 2. Because the movable plate assembly 2 can move along the fixed plate 1, and the locking member 21 cooperates with the first adjustment part 12 to lock or unlock the movable plate assembly 2, when the exhaust fan needs to be installed, the fixed plate 1 and the movable plate assembly 2 are adjusted to the corresponding position on the windowsill, and locked by the locking member 21, so that one end of the fixed plate 1 is engaged with the windowsill, and one end of the movable plate assembly 2 is engaged with the other side of the windowsill, thus completing the installation of the exhaust fan. When disassembly is required, only the locking member 21 needs to be operated to remove the exhaust fan, avoiding the need to drill through holes in the wall or glass window. Installation and disassembly are very simple and convenient.

[0030] As a specific embodiment and not a limitation, in order to lock the first movable plate 22 onto the fixed plate 1, the first adjusting part 12 is arranged along the length direction of the fixed plate 1. The movable plate assembly 2 includes the first movable plate 22, which has a first locking hole 221 corresponding to the first adjusting part 12. The locking member 21 passes through the first adjusting part 12 and engages with the first locking hole 221 for fixation. In this application, the locking member 21 is a bolt, and the first adjusting part 12 is a through groove. By passing the locking member 21 through the first adjusting part 12, one end of the locking member 21 is threaded into the first locking hole 221, and the other end of the locking member 21 abuts against the fixed plate 1. When it is necessary to lock the first movable plate 22, the locking member 21 is turned to apply force to the fixed plate 1, increasing the friction between the fixed plate 1 and the first movable plate 22, thereby locking the first movable plate 22. When it is necessary to unlock, the locking member 21 is simply turned away from the first movable plate 22 to adjust the first movable plate 22.

[0031] Furthermore, to better enable the movable plate assembly 2 to move along the fixed plate 1, a guide rail 13 is provided on the side wall of the fixed plate 1. The guide rail 13 cooperates with the side wall of the movable plate assembly 2 to allow the movable plate assembly 2 to move along the length direction of the fixed plate 1. In this application, the movable plate assembly 2 is inserted into the fixed plate 1 by means of a plug-in connection. The cooperation between the side wall of the movable plate assembly 2 and the guide rail 13 restricts the movable plate assembly 2 to move only along the direction of the guide rail 13.

[0032] In one specific implementation, to ensure more stable movement of the movable plate assembly 2 along the fixed plate 1, an abutment plate 23 extends from the side wall of the movable plate assembly 2, and the abutment plate 23 abuts against the inner wall of the guide rail 13. By placing lubricant between the abutment plate 23 and the guide rail 13, the friction between the abutment plate 23 and the guide rail 13 is reduced. The guide rail 13 wraps around the abutment plate 23, making the movement of the movable plate assembly 2 relative to the fixed plate 1 more stable and the adjustment smoother.

[0033] Furthermore, to more effectively exhaust indoor polluted air to the outside, the exhaust assembly 3 includes an air guide plate 32, which passes through the mounting opening 11 and is fixed to the fixing plate 1. The inner wall of the air guide plate 32 forms an air guide channel 321, within which a fan 31 for exhaust is installed. Because the air guide channel 321 connects the indoor and outdoor spaces, when the fan 31 is activated, it accelerates airflow, guiding the polluted indoor air from the air guide channel 321 to the outside, thus achieving the exhaust of polluted air. Additionally, multiple exhaust fans can be installed indoors to further accelerate indoor air circulation, making it easier to exhaust indoor air.

[0034] As a specific implementation and not a limitation, in order to fix the exhaust assembly 3 to the fixing plate 1, a fixing bracket 4 for fixing the exhaust assembly 3 is included. One end of the fixing bracket 4 is fixed to the outer wall of the air guide plate 32, and the other end is fixed to the fixing plate 1. The fixing bracket 4 is an L-shaped bracket. One end of the fixing bracket 4 is fixed to the outer wall of the air guide plate 32 by bolts, and the other end is fixed to the fixing plate 1 by bolts, thus achieving the fixing of the exhaust assembly 3. In addition, multiple fixing brackets 4 are provided.

[0035] Furthermore, to make the locking member 21 more stable when locked, a washer 211 is included, which is sleeved on the locking member 21. The washer 211 increases the friction between the locking member 21 and the fixing plate 1, and the washer can play a good cushioning role, so that the fixing plate 1 will not be damaged when the locking member is locked.

[0036] The specific working principle of this embodiment is as follows:

[0037] When an exhaust fan needs to be installed, the fixed plate 1 and the first movable plate 22 are placed on the windowsill, and the position of the first movable plate 22 relative to the fixed plate 1 is adjusted so that the fixed plate 1 and the first movable plate 22 are respectively engaged on the windowsill. The first movable plate 22 is then locked by the locking piece 21, thus completing the installation of the exhaust fan. When disassembly is required, simply turn the locking piece 21 to unlock the first movable plate 22, thereby disassembling it. This avoids drilling through holes in the wall or glass window, making installation and disassembly very simple and convenient.

[0038] Example 2:

[0039] Reference Figures 6 to 8 As shown, the main difference between this embodiment and Embodiment 1 is that the movable plate assembly 2 includes a second movable plate 24 that can move along the first movable plate 22. In this embodiment, a total of three plates are provided: a fixed plate 1, a first movable plate 22, and a second movable plate 24. The purpose is to accommodate the installation of some large windows. Both the first movable plate 22 and the second movable plate 24 can be adjusted to achieve installation on large windows.

[0040] As a specific implementation and not a limitation, in order to fix the second movable plate 24 on the first movable plate 22, the second movable plate 24 is provided with a second adjustment part 241 arranged along the length direction of the second movable plate 24, and the first movable plate 22 is provided with a second locking hole 222 at one end away from the first locking hole 221. The locking member 21 passes through the second adjustment part 241 and cooperates with the second locking hole 222 to fix it. In this application, the locking member 21 is a bolt, and the second adjusting part 241 is a through groove. The locking member 21 passes through the second adjusting part 241, so that one end of the locking member 21 is threadedly engaged with the second locking hole 222, and the other end of the locking member 21 abuts against the first movable plate 22. When it is necessary to lock the second movable plate 24, the locking member 21 is turned to apply force to the first movable plate 22, which increases the friction between the second movable plate 24 and the first movable plate 22, thereby locking the second movable plate 24. When it is necessary to unlock, the locking member 21 is simply turned to move away from the second movable plate 24, so that the second movable plate 24 can be adjusted.

[0041] The specific working principle of this embodiment is as follows:

[0042] When an exhaust fan needs to be installed, the fixed plate 1, the first movable plate 22, and the second movable plate 24 are placed on the windowsill. The relative positions of the fixed plate 1, the first movable plate 22, and the second movable plate 24 are adjusted so that they are snapped onto the windowsill. The locking piece 21 is then used to fix them in place, thus achieving the installation of the exhaust fan. When disassembly is required, simply turn the locking piece 21 to unlock the first movable plate 22 and the second movable plate 24, and adjust their positions to disassemble them. Because of its large range of adjustable length, it is very suitable for large windows.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
