Description

Technical Field

[0001] The utility model belongs to the technical field of fans, and in particular relates to an axial flow fan. Background Art

[0002] In the traditional design of axial flow fans, the cylindrical frame often adopts an integrated structure, tightly integrating key components such as fan blades and drive motors. Although such a design ensures the stability and durability of the fan structure, it also exposes some shortcomings in actual applications.

[0003] First, when the axial fan needs to be repaired or parts replaced, the traditional fixed cylindrical frame structure often makes the disassembly process complicated and time-consuming. Because the components are tightly connected, special tools are usually required for disassembly, which not only increases the difficulty of maintenance, but also may damage other parts of the fan due to improper operation.

[0004] Secondly, as the axial fan is used for a longer time, dust and dirt are easily accumulated on the fan blades and drive motor, affecting the fan's heat dissipation effect and operating efficiency. However, due to the limitations of the traditional fan structure, it is very difficult to thoroughly clean these parts, and even the fan needs to be completely disassembled, which undoubtedly increases the cost and difficulty of maintenance.

[0027] The following describes the embodiments of the present invention in detail. Figures 1 to 3 , wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0030] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0031] In the embodiment of the utility model, this case provides an axial flow fan, including a hollow cylindrical frame 100, a fan blade 200 and a drive motor 300. The cylindrical frame 100 is composed of a fixed shell 110 and a movable shell 120. The inner side wall of the movable shell 120 is fixed with a drive motor 300, and the drive end of the drive motor 300 is connected to the fan blade 200. The first end of the movable shell 120 and the first end close to the fixed shell 110 are hinged to each other so that the movable shell 120 rotates on the fixed shell 110. The second end of the movable shell 120 and the second end close to the fixed shell 110 are connected by a locking assembly 400.

[0032] Specifically, the introduction of the movable housing 120 makes the disassembly of the cylindrical frame 100 simple and quick. When maintenance or replacement of parts is required, the movable housing 120 can be easily rotated by simply unlocking the locking assembly 400, so that the internal structure of the fan is exposed, which is convenient for operators to perform disassembly and maintenance work. This not only improves the maintenance efficiency, but also reduces the risk of damaging the fan due to improper operation. The easy-to-disassemble structure makes it easier to clean and maintain the axial flow fan. During long-term use, by optimizing the design of the locking assembly 400, it is possible to ensure that the connection between the movable housing 120 and the fixed housing 110 is firm and reliable, and prevent loosening or falling off during use. This not only ensures the stability of the fan operation, but also improves its safety.

[0033] In another embodiment of the utility model, the locking assembly 400 includes a twisting assembly 410 and a clamping member 420, wherein the twisting assembly 410 is disposed at the second end of the fixed housing 110, and the clamping member 420 is disposed at the second end of the movable housing 120. The twisting assembly 410 includes a fixed rod 411 and a twisting handle 412, wherein a connecting seat 430 is disposed at the second end of the fixed housing 110, and a rotatable rotating connecting portion 440 is disposed on the connecting seat 430, wherein the other end of the rotating connecting portion 440 is connected to the fixed rod 411, and the twisting handle 412 is threadedly connected to the fixed rod 411. The second end of the movable housing 120 is connected to the clamping member 420, and an opening groove 450 is disposed at one end of the clamping member 420, wherein the fixed rod 411 is clamped in the opening groove 450. Specifically, the design of the twisting assembly 410 allows the user to operate the locking assembly 400 by a simple rotation action. By rotating the twisting handle 412, the user can easily adjust the position of the fixed rod 411, thereby locking or unlocking the movable housing 120. This operation method is intuitive and easy to master, without the need for special tools or complicated steps, which greatly improves the convenience of operation. The tightening assembly adopts the cooperation of the clamping member 420 and the fixing rod 411 to achieve a firm connection between the movable housing 120 and the fixed housing 110. The fixing rod 411 is clamped in the opening groove 450 of the clamping member 420. This design makes the connection tighter and less likely to loosen. At the same time, the fixing rod 411 of the twisting assembly 410 is connected to the twisting handle 412 by threading, which further enhances the stability of the connection and ensures that the fan will not loosen due to vibration or external force during operation.

[0034] In another embodiment of the utility model, the driving end of the driving motor 300 is connected to the rotating disk 500, and a plurality of evenly distributed fan blades 200 are connected around the rotating disk 500, and the fan blades 200 are detachably connected to the rotating disk 500. By designing the fan blades 200 and the rotating disk 500 to be detachably connected, when the fan blades 200 are worn or damaged due to long-term use, the user can easily remove and replace new fan blades 200 without replacing the entire rotating disk 500 or the driving motor 300. This design greatly simplifies the maintenance process, improves maintenance efficiency, and reduces maintenance costs.

[0035] In another embodiment of the utility model, a support seat 600 is provided on the inner wall of the movable shell 120, and a connecting seat 610 is provided at the lower end of the driving motor 300. The support seat 600 and the connecting seat 610 are connected by screws to enhance the stability between the driving motor 300 and the movable shell 120.

[0036] In another embodiment of the utility model, the outlet end of the bottom surface of the cylindrical frame 100 is connected to a protective plate 700 for preventing touching. When the axial flow fan is running, the air flow speed at its outlet end is relatively fast. If the user accidentally touches the outlet end, he may feel uncomfortable or injured. By connecting the protective plate 700 to the outlet end, the user's fingers or other objects can be effectively prevented from directly contacting the high-speed airflow, thereby greatly reducing the safety risks caused by touching.

[0037] In another embodiment of the utility model, a plurality of evenly distributed reinforcing ribs 710 are provided on the outer side wall of the cylindrical frame 100. As an additional supporting structure, the reinforcing ribs 710 can effectively disperse and withstand the vibration and impact force generated when the fan is running. By being evenly distributed on the outer side wall of the cylindrical frame 100, the reinforcing ribs 710 significantly improve the stability and rigidity of the entire structure and reduce the risk of structural loosening or deformation caused by vibration.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
