DETAILED DESCRIPTION

[0024] In home use, due to the small area of ​​the room, which is not as wide as public places, and the horsepower of household fans is weak, in order to better cool down, the fan is generally placed very close to people to operate, which will increase the risk of objects being sucked into the fan, causing danger to people and increasing the possibility of fan damage. Generally, improved household fans do not have protection functions and cannot protect people when the fan is placed very close to people. There is a chance that objects will get close to the fan during human activities, which may cause damage to the fan and danger to people.

[0025] like Figure 1-Figure 4 As shown, at least a base assembly 100 is included. The base assembly 100 has an outward extension function and can be locked at a specified position to expand the protection range. Specifically:

[0026] The base assembly 100 includes a fan body 101, which is the main body of the electric fan. A slide groove 102 is provided on the left side of the fan body 101. A slide rod 103 is slidably connected in the slide groove 102. A top frame 104 is provided above the slide rod 103. The sliding top frame 104 expands the protection range of the fan body 101. When in use, the fan body 101 will not be directly contacted, thereby reducing the possibility of objects being caught by the fan blades and increasing safety.

[0027] The dust blocking assembly 200 is slidably connected to the base assembly 100 and can block the left side of the base assembly 100 to protect it and prevent dust from blocking the flow of wind;

[0028] The dust-swatting component 300 can cover the dust-blocking component 200 and can shake off the dust on the dust-blocking component 200 by sliding;

[0029] The dust blocking assembly 200 includes a block 201, a slot 105 is provided on the top of the top frame 104, the block 201 is slidably connected to the slot 105, a clamp ring 202 is provided at the bottom of the block 201, the clamp ring 202 can be slid out to facilitate dust cleaning, and a plurality of filter plates 203 are provided inside the clamp ring 202. After the top frame 104 is extended, the overall area where dust will fall increases, affecting the normal use of the fan body 101. The filter plate 203 can block dust from entering the interior during ventilation, thereby preventing dust from entering the fan body 101. The assembly 300 includes a rotating disk 301, a connecting rod 302 is provided on one side of the rotating disk 301, a rotating shaft 303 is provided on the rear side of the connecting rod 302, a rotating hole 106 is provided on the left side of the top frame 104, the rotating shaft 303 is rotatably and slidably connected with the rotating hole 106, the rotating disk 301 can be inserted into the inside of the clamping ring 202, and the rotating disk 301 can be controlled by sliding and rotating to block dust when not in use, and after the clamping ring 202 is extended, the rotating disk 301 can be slid to beat multiple filter plates 203 for dust cleaning;

[0030] To fix the turntable 301, two sliding holes 304 are provided inside the connecting rod 302, and an insert block 305 is slidably connected in one of the sliding holes 304. A slot 107 is provided on the left side of the top frame 104. The insert block 305 can be connected to different slots 107 to fix the turntable 301 above or below the rotating shaft 303.

[0031] Considering that the top frame 104 may be loose, a plug rod 108 is slidably connected to one side of the top frame 104, and a plurality of plug holes 109 are provided on one side of the fan body 101. The plug holes 109 are adapted to the plug rods 108. The plug rods 108 are plugged into different plug holes 109 to fix the position of the top frame 104.

[0032] In order to prevent the clamping ring 202 from loosening, a groove 204 is opened on one side of the clamping block 201. A baffle 205 is slidably connected in the groove 204. The baffle 205 is hung with the top frame 104 to limit the clamping ring 202.

[0033] The improvement of this embodiment is that the fan body 101 is protected by sliding and positioning the top frame 104, and dust can be blocked and removed by sliding the plurality of filter plates 203 and the rotating disk 301, so that the top frame 104 will not affect the normal cooling rate of the fan body 101;

[0034] In summary, the working principle of the present invention is as follows: first, pull out the insert block 305 from the current sliding hole 304. When in use, first slide and rotate the connecting rod 302 to rotate the turntable 301 to the bottom of the rotating shaft 303. Then, insert the insert block 305 through another sliding hole 304 and insert it into the slot 107. Then, slide the top frame 104 to the left. The sliding insert rod 108 is inserted into the nearest socket 109 to fix the position of the top frame 104. If dust is needed, slide the baffle 205 and then slide the retaining ring 202 to the left. After extending the retaining ring 202, the turntable 301 can be reset. Sliding the turntable 301 and tapping the retaining ring 202 can be used for dust cleaning.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
