[0018] The temporary exhaust fan assembly provided by this utility model will be explained and described in detail below with reference to the accompanying drawings.

[0019] The temporary exhaust fan assembly provided by this utility model is mainly used for high-power experiments and other activities in small, enclosed spaces such as modular power plants. It provides temporary ventilation, can be quickly installed when needed, and can be quickly disassembled after use without damaging the structure of the enclosure. The following detailed description of this utility model is provided in conjunction with specific embodiments: This utility model provides a temporary exhaust fan assembly, such as... Figure 1 , Figure 2 As shown, it includes a mounting bracket 1 and a fan 2. The fan 2 is mounted on the mounting bracket 1. The mounting bracket 1 can be conveniently and quickly fixed to the window of the cabin. Alternatively, in a small space, the mounting bracket 1 can also be fixed to the floor and ceiling so that the fan 2 faces the air outlet.

[0020] In some embodiments, the mounting bracket 1 includes a connecting bracket 11 and a support bracket, which are connected as a whole. The connecting bracket 11 is used for mounting the fan 2. The support bracket is connected to the connecting bracket 11 and has an adjustable length. The support bracket is used to support the connecting bracket 11 between two bearing surfaces and to fix it. For example, the support bracket can be supported on the upper or lower wall or the left or right wall of the window so that the fan 2 faces the window and can exhaust indoor air through the fan 2.

[0021] In this embodiment, the fan 2 includes a housing 21, a motor, and fan blades 22. The housing 21 has a square structure with a circular ventilation channel formed at its center. The motor is mounted inside the ventilation channel via a support arm. The fan blades 22 are connected to the drive shaft of the motor, and the motor drives the fan blades 22 to rotate, providing the driving force for airflow. Optionally, the housing 21 is provided with a connection hole for connection to the connecting bracket 11. Optionally, a protective net is provided on the air inlet side of the housing 21. This can prevent foreign objects from entering the ventilation channel of the fan 2 and damaging the fan blades 22, and can also prevent the fan blades 22 from causing injury to personnel.

[0022] In some embodiments, the connecting frame 11 is a square frame structure with multiple connecting ears on the inner side of its frame. These connecting ears are used for mounting the fan 2. For example, the connecting holes on the housing 21 of the fan 2 are connected to the connecting ears via connectors. Optionally, the connecting frame 11 has one or more mounting positions, each mounting position housing one fan 2. In this embodiment, only one fan 2 is provided. In other embodiments, multiple mounting positions can be provided, allowing multiple fans 2 to be installed to improve ventilation efficiency. It is readily apparent that the number of fans 2 matches the size of the ventilation window. When the ventilation window is large, multiple fans 2 can be installed, such as two or three, while when the ventilation window is small, only one fan 2 is needed.

[0023] The support frame includes a first support section and a second support section disposed on both sides of the connecting frame 11. The first support section and the second support section are integrally connected to the connecting frame 11. Optionally, the first support section, the second support section, and the connecting frame 11 are integrally formed. The first support section includes two parallel first support rods 12, and the second support section includes two parallel second support rods 13. Optionally, the corresponding first support rods 12 and second support rods 13 are coaxial.

[0024] Optionally, the first support rod 12 and the second support rod 13 can both be configured as telescopic structures, or one of the first support rod 12 or the second support rod 13 can be configured as a telescopic structure, changing its length by telescoping, so that the first support rod 12 and the second support rod 13 can be supported between the two bearing surfaces to play a fixing role. Further, as... Figure 1 , Figure 3 As shown, both the free ends of the first support rod 12 and the second support rod 13 are provided with support plates 14, which can increase the contact area with the bearing surface and improve stability. For example, an anti-slip layer 141 can also be provided on the support plate 14 to increase the friction with the contact surface, thereby further improving stability. The anti-slip layer 141 can be, for example, a rubber pad, and anti-slip grooves or patterns can be provided on the part in contact with the bearing surface.

[0025] In some embodiments, such as Figure 2 , Figure 4As shown, the first support rod 12 is a sleeve structure, including a first outer tube 121 and a first inner tube 122. The first outer tube 121 is fixedly connected to the connecting frame 11, and the first inner tube 122 is telescopically disposed inside the outer tube. The overall length of the first support rod 12 can be adjusted by sliding the first inner tube 122. Multiple locking holes 1211 are distributed along the axial direction of the first outer tube 121, and an elastic locking pin is provided on the first inner tube 122. The elastic locking pin can extend through the locking holes 1211 at different positions. For example, when the elastic locking pin is pressed back, the first inner tube 122 can slide inside the first outer tube 121. When the elastic locking pin slides to the position corresponding to the locking hole 1211, it can pop out, thus locking the first inner tube 122 so that it can no longer slide through the elastic locking pin and the locking hole 1211. Optionally, a guide structure is provided between the first outer tube 121 and the second inner tube 132. For example, both the first outer tube 121 and the first inner tube 122 are recessed inward to form a concave structure, and the concave structure extends axially. The concave structure of the first outer tube 121 is embedded into the groove formed by the concave structure of the first inner tube 122, forming a sliding fit to limit the first inner tube 122 and prevent relative rotation between the first inner tube 122 and the first outer tube 121. The length of the first inner tube 122 can be quickly and extensively adjusted within a set range by means of the first support rod 12.

[0026] In some embodiments, such as Figure 2 , Figure 4 As shown, the second support rod 13 is a sleeve structure, including a second outer tube 131 and a second inner tube 132. The second outer tube 131 is fixedly connected to the connecting frame 11. The second inner tube 132 is telescopically disposed inside the outer tube. The second inner tube 132 and the second outer tube 131 can slide relative to each other to achieve telescopic movement, and the length of the second support rod 13 can be changed by telescopic movement. A connecting sleeve 133 is provided at the end of the second outer tube 131. The connecting sleeve 133 is sleeved on the outside of the second outer tube 131 and rotatably connected to the second outer tube 131. The inner wall of the connecting sleeve 133 is provided with internal threads, and the outer wall of the second inner tube 132 is provided with external threads. The second inner tube 132 and the connecting sleeve 133 are threadedly connected. Rotating the connecting sleeve 133 can cause the second inner tube 132 to extend or retract. For example, when the connecting sleeve 133 rotates clockwise, the second inner tube 132 can extend outward, and when the connecting sleeve 133 rotates counterclockwise, the second inner tube 132 retracts inward. The length of the second support rod 13 can be adjusted within a small range via the connecting sleeve 133, allowing it to contact the bearing surface and provide a certain clamping force to ensure reliable fixing. In this application, the cooperation between the first support rod 12 and the second support rod 13 enables quick installation and provides a certain clamping force to ensure reliable installation.

[0027] In some embodiments, a battery is disposed within the first outer tube 121 and / or the second outer tube 131, and the battery is electrically connected to the fan 2. Optionally, both the first outer tube 121 and the second outer tube 131 have hollow interiors, providing space for battery installation. The battery is connected to the motor of the fan 2, providing power to the motor, allowing the fan 2 to operate without an external power source. This makes the temporary exhaust fan assembly more flexible and unrestricted by location or power supply limitations. Further, depending on the battery capacity, the battery can be disposed within one of the first outer tubes 121 or the second outer tube 131, or batteries can be disposed in all of the first outer tubes 121 and the first inner tube 122. Preferably, batteries are disposed in a portion of the first outer tubes 121 or the second outer tube 131, sufficient to allow the fan 2 to operate for a certain period of time, such as 1-3 hours, avoiding excessively large batteries and thus reducing the overall weight. Optionally, the first outer tube 121 or the second outer tube 131 has a charging interface at the location where the battery is disposed, for charging the battery from an external power source. As is easy to imagine, both a battery and an external power connector can be installed simultaneously. Fan 2 can be powered by either the built-in battery or an external power source, further enriching its usage methods and making it more widely applicable.
