[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0026] Referring to Figures 2 - 4 , an embodiment provided by the present utility model: A household variable-frequency fan includes a base 1, a fan main body 3 is fixedly connected to the rear side of the top end of the base 1, a rear wind cover 4 is fixedly connected to the outer wall of the top end of the fan main body 3, a clamping body 6 fixedly connected to the four sides of the outer wall of the rear wind cover 4, a clamping post 7 is fixedly connected to the four sides of the inner wall of the front wind cover 5, the shapes of the clamping body 6 and the clamping post 7 are matched to connect the front wind cover 5 and the rear wind cover 4, a plurality of support plates 8 are fixedly connected to the inner wall of the front wind cover 5, the support plates 8 have the same height as the clamping post 7 and the clamping body 6, and the front wind cover 5 is located on the outer wall of the rear wind cover 4. Referring to Figure 5, on the four sides of the outer wall of the front wind cover 5, swing arms 9 are rotatably connected, including inserting rods 10 that are all slidably connected to the inner wall of the swing arms 9. On the four sides of the rear end of the rear wind cover 4, inserting holes 13 are opened. The inserting rods 10 and the inserting holes 13 are in a matching shape. At the rear ends of the inserting rods 10, handles 11 are fixedly connected. Around the outer walls of the inserting rods 10, springs 12 are wound. The rear ends of the springs 12 are fixedly connected to the front ends of the handles 11, and the front ends of the springs 12 are fixedly connected to the rear ends of the swing arms 9, which are used to strengthen the connection between the front wind cover 5 and the rear wind cover 4. At the four sides of the bottom end, universal wheels 2 are installed, which are used to facilitate the movement of the whole fan.
[0027] Specifically, when in use, the fan will blow the dust in the air into the interior, causing the interior of the front wind cover 5 and the rear wind cover 4 to accumulate dust layers. And it is not possible to clean the interior of the front wind cover 5 and the rear wind cover 4 well from the outside. At this time, the handle 11 on the swing arm 9 can be pulled backward to the rear side of the rear wind cover 4. The inserting rod 10 is driven by the handle 11 to move backward into the inserting hole 13 on the rear wind cover 4. Then the swing arm 9 is turned outward to the front wind cover 5, thus releasing the locking of the front wind cover 5 and the rear wind cover 4. Then rotate the front wind cover 5 to drive the clamping post 7 to move, so that the clamping post 7 moves out of the clamping body 6, causing the front wind cover 5 and the rear wind cover 4 to separate. At this time, the interior of the front wind cover 5 and the rear wind cover 4 can be cleaned of dust. After cleaning, the clamping post 7 on the front wind cover 5 is aligned with the clamping body 6 on the rear wind cover 4 and put in. Then rotate the front wind cover 5 to drive the clamping post 7 to move into the clamping body 6. Then pull the handle 11 to drive the inserting rod 10 to move. The handle 11 will stretch the spring 12 at the same time. After turning the swing arm 9 to the rear of the rear wind cover 4, release the handle 11, and the spring 12 will pull back the handle 11 to drive the inserting rod 10 to insert into the inserting hole 13, installing the front wind cover 5 and the rear wind cover 4 together.
[0028] Refer to Figure 1 , Figure 6 and Figure 7 , at the top end of the base 1, a water storage tank 14 is fixedly connected. At the bottom end of the inner wall of the water storage tank 14, a pump body 15 is fixedly connected. An annular water tank 17 is opened on the inner wall of the rear wind cover 4. A water outlet pipe 16 fixedly connected to the top end of the pump body 15, and the other end of the water outlet pipe 16 is fixedly connected to the inner wall of the annular water tank 17. At the bottom inner wall of the annular water tank 17, a partition plate 19 is fixedly connected. On the inner wall of the annular water tank 17 at the left end of the partition plate 19, a water inlet pipe 18 is fixedly connected. The other end of the water inlet pipe 18 is fixedly connected to the top end of the water storage tank 14, which is used to circulate the water inside the water storage tank 14 in the annular water tank 17 to reduce the temperature inside the fan.
[0029] Specifically, there are control buttons on the fan body 3. The buttons operate and control the fan body 3 and the pump body 15 through electrical connection. When the fan is in use, the pump body 15 can be started. The pump body 15 transports the water in the water storage tank 14 to the annular water tank 17 in the rear wind cover 4 through the water outlet pipe 16. The water circulates in the annular water tank 17, thereby reducing the overall temperature inside the fan and making the wind blown by the fan cooler. The partition plate 19 in the annular water tank 17 separates the bottom, so that the water can only fill the right side of the annular water tank 17, then reach the left water inlet pipe 18 from the top of the annular water tank 17, and then return to the water storage tank 14 from the water inlet pipe 18, so as to make the water circulate in the annular water tank 17.
[0030] Working principle: After long-term use, there will be dust layers inside the front wind cover 5 and the rear wind cover 4, and it is not possible to clean the inside well from the outside. At this time, the handle 11 on the swing arm 9 can be pulled backward to the rear side of the rear wind cover 4. The handle 11 drives the insertion rod 10 to move backward out of the jack 13 on the rear wind cover 4, and then the swing arm 9 is turned outward to the front wind cover 5, thus releasing the locking of the front wind cover 5 and the rear wind cover 4. Then rotate the front wind cover 5 to drive the clamping column 7 to move, so that the clamping column 7 moves out of the clamping body 6, so that the front wind cover 5 and the rear wind cover 4 are separated. At this time, the inside of the front wind cover 5 and the rear wind cover 4 can be cleaned of dust. During the use of the fan, the pump body 15 can be started. The pump body 15 transports the water in the water storage tank 14 to the annular water tank 17 in the rear wind cover 4 through the water outlet pipe 16. The water in the annular water tank 17 will reduce the overall temperature inside the fan and make the wind blown by the fan cooler. The partition plate 19 in the annular water tank 17 separates the bottom, so that the water can only fill the annular water tank 17 and reach the left water inlet pipe 18 from the top of the annular water tank 17, and then return to the water storage tank 14 from the water inlet pipe 18.
[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
