Abstract
Description
Technical Field
[0001] This utility model relates to the field of tower fan technology, specifically a tower fan with an easily detachable fan drum. Background Technology
[0002] Tower fans derive their name from their slender and upright shape, resembling a tall building. Based on aerodynamic principles, they create a three-dimensional air exchange system between indoor and outdoor air, similar to a blower in a stove, capable of delivering air even without fan blades. Tower fans use a motor to drive a cross-flow impeller (blower), generating air pressure and centrifugal force, which is then distributed through internal airflow guide walls. Because the cross-flow impeller is typically cylindrical, tower fans create a three-dimensional wall of airflow, or "air curtain," perpendicular to the ground, which oscillates and blows air from side to side.
[0003] During the use of tower fans, it is necessary to clean the back cover or filter. Existing tower fans are fixed in multiple positions with multiple screws. When disassembling, tools are needed to disassemble them one by one. This assembly method is cumbersome and not conducive to disassembly and cleaning. Utility Model Content
[0004] The purpose of this invention is to provide a tower fan with an easily detachable blower to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tower fan with a conveniently detachable fan drum, comprising:
[0006] Base;
[0007] Mounting plate, the mounting plate is placed on top of the base, a limiting plate is fixedly connected to one side of the mounting plate, a blower is rotatably connected below the limiting plate, a polygonal column is fixedly connected to the end of the blower, and a polygonal tube that cooperates with the polygonal column is raised and lowered below the limiting plate.
[0008] An air inlet filter is placed on one side of the air outlet hood.
[0009] Preferably, an air outlet cover is fixedly connected to one side of the mounting plate where the air is vented, and a motor is fixedly connected to one side of the mounting plate.

[0021] 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.
[0022] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a technical solution: a tower fan with a conveniently detachable air blower, comprising: a base 1 having a conical structure; a mounting plate 9 rotatably mounted on the top of the base 1, a limiting plate 11 fixedly connected to one side of the mounting plate 9, an air blower 16 rotatably connected below the limiting plate 11, a polygonal column 15 fixedly connected to the end of the air blower 16, and a polygonal tube 14 that cooperates with the polygonal column 15 being raised and lowered below the limiting plate 11; and an air inlet filter 3 snapped onto one side of the air outlet hood 2.
[0023] It should be noted that the blower 16 driven by the motor 10 of this utility model rotates. The blower 16 is a metal tube with a hollow structure formed by multiple inclined plates. When the blower 16 driven by the motor 10 rotates, the blower 16 introduces air from the air inlet filter 3 and blows it out through the air outlet hood 2. When cleaning the air inlet filter 3, the fastening nut 5 on the outside of the semi-threaded post 4 at the top of the air inlet filter 3 is removed. The air inlet filter 3 is slid down and removed for cleaning. When disassembling the blower 16, the polygonal tube 14 is slid to separate from the polygonal post 15 and the middle part of the blower 16 is removed. There is no need to disassemble the limiting plate 11, which makes the disassembly and cleaning of the blower 16 simpler.
[0024] Please see Figure 2 As shown, an air outlet cover 2 is fixedly connected to one side of the mounting plate 9 where the air is vented, and a motor 10 is fixedly connected to one side of the mounting plate 9.
[0025] It should be noted that the air outlet cover 2 of this utility model has multiple air outlet holes in the middle, and the motor 10 drives the blower 16 to rotate to achieve air blowing.
[0026] Please see Figure 2 , 4 As shown, a rotating shaft 12 is rotatably connected to the middle of the limiting disk 11. A polygonal tube 14 is slidably connected to both the output end of the motor 10 and the outer side of the rotating shaft 12. A limiting groove 13 is opened on both the output end of the motor 10 and the outer side of the rotating shaft 12. A slider matching the limiting groove 13 is provided in the middle of the polygonal tube 14. A through hole is provided on the outer side of the polygonal tube 14. A threaded hole is opened on the polygonal column 15 corresponding to the position of the through hole.
[0027] It should be noted that when disassembling the blower 16, the air inlet filter 3 is removed first, then the screws on the outside of the polygonal tube 14 are removed, and then the polygonal tube 14 is slid along the limiting groove 13 to separate the polygonal tube 14 from the polygonal column 15. Then the blower 16 is removed from the middle. During installation, the blower 16 is placed between the rotating shaft 12 and the motor 10, and the polygonal tube 14 is slid down and fitted onto the outside of the polygonal column 15. Then the two are fixed with screws. The polygonal tube 14 at the output end of the motor 10 is connected to the corresponding polygonal column 15, and then the above operation is repeated.
[0028] Please see Figure 2 , 3 As shown, a fixed cover plate 8 is fixedly connected to one side of the mounting plate 9. A semi-threaded post 4 is fixedly connected to the top of the fixed cover plate 8 and the top of the limiting groove 13. When the air inlet filter 3 is combined with the fixed cover plate 8, the two semi-threaded posts 4 form a complete threaded rod. A fastening nut 5 is threadedly connected to the outer side of the threaded rod. Multiple limiting protrusions 7 are vertically installed on both sides of the fixed cover plate 8. Limiting slots 6 with openings facing upward and cooperating with the limiting protrusions 7 are provided on both sides of the air inlet filter 3. A sliding groove for the air inlet filter 3 to slide up and down is provided on one side of the fixed cover plate 8.
[0029] It should be noted that the fixed cover plate 8 and the mounting plate 9 of this utility model are connected by screws. The air inlet filter 3 is connected to the fixed cover plate 8. The air inlet filter 3 is installed into the groove on one side of the fixed cover plate 8. Then the air inlet filter 3 is slid upward so that the limiting protrusion 7 is inserted into the limiting slot 6 of the air inlet filter 3. When the air inlet filter 3 moves upward to the limit position, the air inlet filter 3 and the semi-threaded post 4 at the top of the fixed cover plate 8 form a complete threaded post. The fastening nut 5 is threaded on the outside of the semi-threaded post 4, thereby limiting the two semi-threaded posts 4 to the left and right and up and down. When disassembling, one fastening nut 5 can be removed directly, which facilitates the disassembly of the blower 16 and the cleaning of the air inlet filter 3.
