Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 In this embodiment of the utility model, a folding electric fan with mosquito-repellent function includes a base 1, a battery 2 disposed inside the base 1, a storage slot 3 on the top of the base 1, a telescopic tube 4 disposed inside the storage slot 3, one end of the telescopic tube 4 being rotatably connected to the base 1, and the other end of the telescopic tube 4 being rotatably connected to a protective mesh cover 9, a fan 10 installed inside the protective mesh cover 9, a box 17 fixedly installed on the rear wall of the protective mesh cover 9, a slot 18 penetrating through the side wall of the box 17, an electric heating element 20 fixedly connected inside the box 17 via a heat insulation seat 19, the electric heating element 20 being a PTC heating element with automatic constant temperature function, an electric mosquito repellent pad 22 disposed inside the slot 18, and the electric mosquito repellent pad 22 being attached to the electric heating element 20, and a switch 11 installed on the outer wall of the protective mesh cover 9.

[0022] This utility model, by adopting the above-mentioned solution, such as Figure 6 As shown, when the electric fan is not in use, the telescopic tube 4 can be retracted to its shortest length and rotated into the storage slot 3, so that the protective net cover 9 is attached to the base 1, thereby greatly reducing the storage space occupied by the electric fan. With the battery 2, the electric fan can run normally for a period of time without relying on an external power source, making it convenient to carry and use when going out.

[0023] When the telescopic tube 4 is not rotated outside the storage slot 3, the protective net cover 9 can be rotated on the telescopic tube 4 to stand up, so that the electric fan can be used as a table fan.

[0024] By rotating the telescopic rod 4 to a vertical position and then rotating the protective mesh cover 9 to make it stand up, this electric fan can be used as a floor fan, thus meeting the different usage needs of users.

[0025] By activating the electric heating element 20, the electric mosquito repellent tablet 22 can be heated, thereby causing the insecticide components inside the electric mosquito repellent tablet 22 to volatilize outward, so as to achieve the effect of repelling and killing mosquitoes. When the fan 10 is running, it can blow the volatilized insecticide far away, so that the insecticide can quickly spread indoors.

[0026] Specific combination Figure 3 and Figure 4 In one embodiment of the present invention, a plurality of trapezoidal strips 21 are fixedly installed on the inner wall of the slot 18 away from the electric heating element 20, the electric mosquito coil 22 is located between the trapezoidal strips 21 and the electric heating element 20, and a plurality of ventilation holes 23 are provided through the outer wall of the slot 18.

[0027] With the trapezoidal strip 21 in place, after the electric mosquito coil 22 is inserted into the slot 18, the trapezoidal strip 21 can press the electric mosquito coil 22 tightly against the surface of the electric heating element 20 to ensure the heating effect of the electric mosquito coil 22.

[0028] Specific combination Figure 3 and Figure 4 Based on the previous embodiment, a rotating shaft 24 is rotatably installed on the outer wall of the box 17. A knob 26 is fixedly connected to one end of the rotating shaft 24 outside the box 17, and a plurality of rollers 25 are fixedly sleeved on the other end of the rotating shaft 24 inside the box 17. Anti-slip textures are provided on the outer peripheral wall of the rollers 25. The electric mosquito coil 22 is located between the rollers 25 and the electric heating element 20, and the rollers 25 are in contact with the electric mosquito coil 22.

[0029] When the electric mosquito repellent pad 22 is inserted into the slot 18, the roller 25 will be in close contact with the surface of the electric mosquito repellent pad 22. When it is necessary to move the electric mosquito repellent pad 22, simply turn the rotating shaft 24 by the knob 26 to drive the roller 25 to rotate, which will drive the electric mosquito repellent pad 22 to move out of the slot 18, thus making it easy to take the electric mosquito repellent pad 22 out of the slot 18.

[0030] Specific combination Figure 1 , Figure 2 and Figure 6In one embodiment of this utility model, the telescopic tube 4 includes a sleeve 12, an inner tube 13, and a core tube 14. The inner tube 13 is located inside the sleeve 12, and the core tube 14 is located inside the inner tube 13. A second conduit 6 is fixedly connected to one end of the core tube 14 outside the inner tube 13. A first conduit 5 is fixedly connected to one end of the sleeve 12 away from the second conduit 6. The first conduit 5 is rotatably connected to the base 1 via a damping shaft. The second conduit 6 is connected to a hollow connecting seat 7 via a damping shaft. The hollow connecting seat 7 is fixedly connected to a protective mesh cover 9. A groove 8 is provided at the top of the base 1 corresponding to the hollow connecting seat 7.

[0031] Furthermore, both the sleeve 12 and the inner tube 13 have a hand-tightening bolt 16 inserted through a threaded hole on the outer wall of the end facing the second conduit 6.

[0032] The hand-tightening bolt 16 facilitates locking the length of the inner tube 13 on the sleeve 12, and also facilitates locking the length of the core tube 14 on the inner tube 13, thereby making it easy to fix the length of the telescopic tube 4 to prevent the telescopic tube 4 from shrinking without human intervention. The use of the damping shaft enables a certain rotational damping between the telescopic tube 4, the base 1, and the hollow connecting seat 7, so as to prevent the base 1 and the protective net cover 9 from rotating relative to the telescopic tube 4 without human intervention.

[0033] Specific combination Figure 2 In one embodiment of this utility model, a wire 15 is provided inside the telescopic tube 4. One end of the wire 15 passes through the first conduit 5 into the base 1, and the other end of the wire 15 passes through the second conduit 6 and the hollow connecting seat 7 into the protective net cover 9. The portion of the wire 15 located inside the telescopic tube 4 is spiral-shaped.

[0034] By using the above-mentioned method to lay out the wire 15, the exposed wire 15 can be avoided, thereby improving the aesthetics of the electric fan. In addition, the wire 15 located inside the telescopic tube 4 is spiral-shaped, thus avoiding interference between the wire 15 and the telescopic tube 4.

[0035] Although the present invention 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 invention should be included within the protection scope of the present invention.
