[0034] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Example 1:

[0037] like Figure 1-10 As shown, a fan that is easy to clean is provided, including a fan head 1, a control component 2, a body rod 3, and a chassis 4, which are installed sequentially from top to bottom. The control component 2 includes at least a circuit board and a button for controlling the fan. The fan head 1 is not limited to being installed in a fixed or rotating manner. Fixed or rotating installation of the fan head 1 to achieve the oscillation function is a conventional technical means for fans, so it will not be described in detail. The body rod 3 is connected by a single rod or multiple rods in a detachable manner. The detachable connection of multiple rods allows the height of the fan head 1 to be adjusted. The detachable connection of multiple rods is not limited to using threaded screws.

[0038] like Figure 2As shown, the head unit 1 includes a fan blade assembly 101, an air duct 102, a rear grille 103, and a front grille 104. The fan blade assembly 101 is installed inside the air duct 102 for blowing air. The fan blade assembly 101 includes at least fan blades and a drive motor. The fan blade assembly 101 is a conventional technique for those skilled in the art, so it will not be described in detail. The air duct 102 has an annular cylindrical structure with open ends for air inlet and air outlet, respectively. The rear grille 103 and the front grille 104 are installed at both ends of the air duct 102, respectively. The rear grille 103 is conventionally fixed with screws in the art.

[0039] like Figure 2 and 3 As shown, a cleaning port 6 is provided at the top of the air duct 102 along the circumference. A baffle 5 is provided at the cleaning port 6. The baffle 5 is limited to sliding and can move along the circumference of the air duct 102 to open or seal the cleaning port 6. The cleaning port 6 is opened by sliding the baffle 5, which is used to clean the inside of the fan head 1 when the fan is off. The cleaning port 6 can be opened by sliding the baffle 5, which is convenient and quick to operate.

[0040] A limit switch 7 is installed on the inner wall of the air duct 102 near one end of the cleaning port 6. When the baffle 5 seals the cleaning port 6, the end of the baffle 5 contacts the limit switch 7, and the fan assembly 101 is energized by the control component 2. When the sliding baffle 5 opens the cleaning port 6, the contact between the baffle 5 and the limit switch 7 is canceled, and the limit switch 7 outputs a signal to the control component 2, which in turn controls the fan assembly 101 to de-energize, thus preventing the fan assembly 101 from rotating while energized when the cleaning port 6 is open, which could pose a safety hazard.

[0041] like Figure 6 As shown, the sliding baffle 5 opens the cleaning port 6, allowing access to both sides of the fan blade assembly 101 and a portion of the inner wall of the air duct 102 during cleaning, making the cleaning operation convenient and quick.

[0042] like Figure 4 and 5 As shown, the inner wall of the air duct 102 is provided with limiting ribs 9. Several limiting ribs 9 are provided and distributed on both sides of the cleaning port 6. A gap is left between the limiting ribs 9 and the inner wall of the air duct 102 for the limiting sliding installation of the baffle 5.

[0043] like Figure 7 As shown, a handle 10 is provided on the outer side of the baffle 5 near the limit switch 7, which makes it easy to pull the baffle 5 to slide.

[0044] like Figure 8As shown, a mounting base 11 is provided at the end of the baffle 5 away from the limit switch 7. A wiping strip 12 is detachably installed on the mounting base 11. The detachable installation includes, but is not limited to, using Velcro. The outer side of the wiping strip 12 is flush with the outer side of the baffle 5. The wiping strip 12 is made of nano-grip and is used to simultaneously wipe the surface covered by the baffle 5 inside the air duct 102 when the baffle 5 is pulled to open the cleaning port 6. This solves the technical problem that only part of the inner wall of the air duct 102 can be touched during cleaning. Furthermore, the wiping strip 12 is detachable, making it easy to remove, clean, or replace.

[0045] like Figure 3 As shown, an inner lining plate 8 is fixedly provided on the inner wall of the air duct 102. The inner lining plate 8 is located in the moving area of ​​the baffle 5 inside the air duct 102 and fully covers the moving area of ​​the baffle 5. The baffle 5 is fitted to the inner wall of the inner lining plate 8, and the wiping strip 12 is fitted to wipe the inner lining plate 8. The movement of the baffle 5 against the inner lining plate 8 improves its movement stability. The movement of the baffle 5 against the inner lining plate 8 generates friction, avoiding friction between the baffle 5 and the air duct 102 and causing wear to the air duct 102.

[0046] like Figure 3 and 9 As shown, the end edge of the front mesh cover 104 installed in the air duct 102 is provided with a first slot 13. Multiple first slots 13 are provided. The back edge of the front mesh cover 104 is provided with a first buckle 14. Multiple first buckles 14 are provided and are adapted to the multiple first slots 13. The first buckles 14 are in an "L" shape. Aligning the first buckle 14 with the first slot 13 and rotating the front mesh cover 104 completes the snap-fit ​​and fixation of the front mesh cover 104. The snap-fit ​​and fixation are convenient and quick, and it is easy to remove the front mesh cover 104 to inspect or clean the inside of the machine head 1. The snap-fit ​​and fixation of the front mesh cover 104 can completely expose the front side of the fan blade of the fan blade assembly 101, further improving the convenience of cleaning.

[0047] In some embodiments, such as Figure 2 , 9 As shown in Figure 10, it also includes an aromatherapy pad 16. The front mesh cover 104 has an installation area in the middle, and the installation area of ​​the front mesh cover 104 has a second slot 15. The back of the aromatherapy pad 16 has a second buckle 17. The aromatherapy pad 16 is fastened to the installation area in the middle of the front mesh cover 104 by the second buckle 17 and the second slot 15. The back of the aromatherapy pad 16 is connected to the outside of the fan, ensuring that the fan blows air through the aromatherapy pad 16 and diffuses it into the air.

[0048] In some embodiments, such as Figure 1 As shown, it also includes an electric mosquito killer 18, which is mounted on the fan, including but not limited to being mounted outside the control component 2.

[0049] In some implementations, such as Figure 1As shown, there is a gap between the upper part of the control component 2 and the head 1. A humidifier 19 is installed on the upper part of the control component 2. The humidifier 19 is not limited to being embedded inside the control component 2, with the output end facing upward. A removable top cover is provided on the top of the humidifier 19, and the top cover is located outside the control component 2 for disassembly and water filling. The humidifier 19 can be replaced with a night light to enable it to function as a night light for nighttime use.

[0050] If the upper part of the control component 2 is configured as a humidifier 19, such as Figure 3 As shown, the bottom of the air duct 102 is provided with several moisture inlets 20. The humidifier 19 blows moisture upward through the moisture inlets 20 and mixes with the air blown out by the fan blade assembly 101 to form humid air, which further reduces the temperature of the blown air and improves the cooling effect.

[0051] Example 2:

[0052] like Figure 11 As shown, it also includes a storage basket 21, which is detachably mounted on the body rod 3 for placing items.

[0053] like Figure 12 As shown, the storage basket 21 has a circular structure. The storage basket 21 has a radial insertion channel 23 along its outer edge. Limiting strips 24 are provided on both sides of the inner side of the insertion channel 23. The length direction of the limiting strips 24 is parallel to the depth direction of the storage basket 21. A support plate 22 is fixedly provided on the outer wall of the body rod 3. The insertion channel 23 of the storage basket 21 passes through the body rod 3, and the limiting strips 24 also pass through the body rod 3 to achieve the locking and limiting of the storage basket 21. The bottom of the storage basket 21 is attached to the upper part of the support plate 22 and is supported by the support plate 22. The storage basket 21 can be removed by pulling it, eliminating the need for installation of the storage basket 21 or for removing the storage basket 21 for cleaning. The setting of the storage basket 21 enables the fan to have a storage function, enhancing its practicality.

[0054] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
