DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figure 1-Figure 5The utility model provides a technical solution: a fan frame that is easy to disassemble and assemble, including a fan frame structure 100 and a fan structure 200.

[0026] See also Figures 1-4 The fan frame structure 100 includes a fan casing 110, a protective frame 140 and a quick-release part 150. The fan casing 110 is provided with an annular groove 111, and the annular groove 111 is provided with a limiting groove 112. The interior of the fan casing 110 is also provided with a cavity groove 114. A plug-in column 141 is fixed on the protective frame 140, and the plug-in column 141 is inserted into the interior of the limiting groove 112. The protective frame 140 is placed in the annular groove 111, and the quick-release part 150 is installed in the interior of the cavity groove 114. The quick-release part 150 is snapped onto the protective frame 140.

[0027] The annular groove 111 further includes a groove 113, within which an elastic member 130 is mounted. The elastic member 130 includes a T-shaped movable post 131 and a spring 132. One end of the spring 132 is fixed to the T-shaped movable post 131, and the other end of the spring 132 is fixed to the interior of the groove 113. The groove 113 is configured to match the T-shaped movable post 131. The T-shaped movable post 131 is slidably connected to the interior of the groove 113. After installation, the protective frame 140 presses the T-shaped movable post 131, causing the T-shaped movable post 131 to move toward the interior of the groove 113, squeezing the spring 132 and causing it to elastically deform. The elasticity of the spring 132 can be used to bounce the protective frame 140 upward, thereby facilitating the protective frame 140 to disengage from the annular groove 111 and facilitate assembly and disassembly. The surface of the fan housing 110 is formed with a notch 120, within which a nail hole 121 is formed. The nail hole 121 facilitates installation with external equipment.

[0028] The quick release part 150 includes a threaded column 151 and a movable insert plate 153. The threaded column 151 is rotatably connected to the interior of the cavity 114. A knob 152 is fixed to the threaded column 151. The movable insert plate 153 is threadedly penetrated on the threaded column 151. The end of the movable insert plate 153 slides through the cavity 114 and is inserted into the interior of the protective frame 140. The movable insert plate 153 is slidably connected to the interior of the cavity 114. A threaded hole matching the threaded column 151 is opened in the interior of the movable insert plate 153. The knob 152 extends to the outside. The cavity 114 A through hole matching the movable insert plate 153 is provided inside 14, and a slot 142 matching the movable insert plate 153 is provided on the surface of the protective frame 140. The end of the movable insert plate 153 is inserted into the inside of the slot 142. Here, the threaded column 151 is rotated by the knob 152 to move the movable insert plate 153 back and forth. When the movable insert plate 153 is inserted into the slot 142, the protective frame 140 can be positioned and fixed. When the movable insert plate 153 is away from the slot 142, the protective frame 140 can be easily disassembled and assembled.

[0029] See also Figures 1-4 The fan structure 200 includes a connecting frame 210 and a fan 220. The connecting frame 210 is clamped in the limiting groove 112, and the plug-in column 141 is placed on the surface of the connecting frame 210. The fan 220 is installed on the connecting frame 210. The fan 220 includes a fan motor 221 and fan blades 222. The fan motor 221 is installed on one side of the connecting frame 210, and the fan blades 222 are installed at the end of the output shaft of the fan motor 221.

[0030] Specifically, the structural principle of the fan frame that is easy to disassemble and assemble is as follows: when disassembling, the threaded column 151 is driven to rotate by rotating the knob 152, so that the movable plug plate 153 will move to one side, and its end will be out of the slot 142 on the protective frame 140. Then, under the elastic action of the spring 132, the T-shaped movable column 131 can be used to bounce the protective frame 140 upward, so that the protective frame 140 is out of the annular groove 111 and can be removed. At the same time, the connecting frame 210 is fixed to the inside of the limiting groove 112 by the plug-in column 141 on the protective frame 140, so that the fan The fan structure 200 can also be removed. When installing, first place the connecting frame 210 with the fan installed in the corresponding limit slot 112, then insert the plug-in column 141 on the protective frame 140 into the limit slot 112, and press the protective frame 140 to squeeze the elastic member 130. At this time, turn the knob 152 to insert the movable plug-in plate 153 into the slot 142 to position and fix the protective frame 140. In this way, during the cleaning, maintenance and disassembly of the fan, the disassembly and assembly operations can be completed without using specific tools, and the user can clean it more simply and conveniently.

[0031] It should be noted that the specific model and specifications of the fan motor 221 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0032] The power supply and principle of the fan motor 221 are clear to those skilled in the art and will not be described in detail here.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
