[0025] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] like Figures 1-4 As shown, the present invention provides a technical solution including an installation component 1, and a fan component 2 is provided inside the installation component 1.
[0027] The mounting assembly 1 includes a mounting pipe 101, an air duct 102 is provided inside the mounting pipe 101, a U-shaped mounting plate 103 is slidably installed inside the air duct 102, and oblique hanging grooves 104 are provided at the top and bottom edges of the front side of the U-shaped mounting plate 103. A sliding groove 105 is provided in the middle of the bottom surface inside the air duct 102. A threaded rod 106 is rotatably installed in the sliding groove 105. A threaded slider 107 is threadedly sleeved on the body of the threaded rod 106. The top surface of the threaded slider 107 is fixedly connected to the middle of the bottom surface of the U-shaped mounting plate 103.
[0028] The fan assembly 2 includes a smoke exhaust fan body 201, and inclined mounting plates 203 are fixedly installed on the top and bottom of the back of the smoke exhaust fan body 201.
[0029] In this embodiment, two inclined mounting plates 203 correspond one-to-one with two inclined mounting slots 104. The inclined mounting plates 203 are movably inserted into the inclined mounting slots 104. The dimensions of the exhaust fan body 201 are adapted to the dimensions of the duct 102. The top, bottom, and two sides of the exhaust fan body 201 are all in contact with the inner wall of the duct 102. The vertical displacement of the exhaust fan body 201 can be restricted by the duct 102. Therefore, the inclined mounting plates 203 cannot detach from the inclined mounting slots 104, thereby allowing the exhaust fan body 201 to be stably installed in the duct 102.
[0030] The vertical part of the T-shaped handle 108 has a threaded fixing rod 109 threadedly inserted at one end of the front, and a fixing threaded opening 110 is provided at the bottom of the front of the installation pipe 101.
[0031] Ventilation panels 202 are provided on the front and back center of the exhaust fan body 201. Several fan-shaped openings are provided on the front of both ventilation panels 202, and the fan-shaped openings are distributed in a ring on the front of the ventilation panels 202.
[0032] One end of the threaded fixing rod 109 is threaded into the fixing threaded port 110, and the threaded slider 107 is slidably installed in the slide groove 105. The T-shaped handle 108 can be fixed by threading one end of the threaded fixing rod 109 into the corresponding fixing threaded port 110, thereby improving the stability of the structure.
[0033] Working principle: Take out the exhaust fan body 201 and align the two oblique hanging plates 203 fixed on its back with the oblique hanging slots 104 on the front of the U-shaped mounting plate 103. After alignment, insert the oblique hanging plates 203 into the oblique hanging slots 104. The oblique hanging plates 203 can stably hang the exhaust fan on the front of the U-shaped mounting plate 103. Then, hold the T-shaped handle 108 and rotate it. The rotation of the T-shaped handle 108 can drive the threaded rod 106 to rotate. The rotation of the threaded rod 106 can cause the threaded slider 107 with its threaded sleeve to move in the sliding groove 105. The movement is achieved by using the threaded slider 107 to move the U-shaped mounting plate 103 into the air duct 102. This movement of the U-shaped mounting plate 103 allows the exhaust fan body 201, which is mounted on its front side, to enter the air duct 102. Once the exhaust fan body 201 is fully inside the air duct 102, its installation is easily completed. The air duct 102 restricts the vertical displacement of the exhaust fan body 201, preventing the inclined mounting plate 203 from detaching from the inclined mounting slot 104. This ensures the exhaust fan body 201 is stably installed within the air duct 102.
[0034] It also allows for convenient disassembly and installation of the exhaust fan body 201. By rotating the threaded rod 106, the U-shaped mounting plate 103 is moved to the front end of the duct 102. At this time, the exhaust fan body 201, which is attached to the front of the U-shaped mounting plate 103, will protrude out of the duct 102. Subsequently, the staff can easily disassemble the exhaust fan body 201 and perform maintenance on it without having to go into the duct 102, making it more practical.
[0035] Although the utility model has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the utility model, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the utility model all belong to the range of protection required by the utility model.
