Example 1

Referring to fig. 1 to 4, a mosquito repelling windowsill comprises a windowsill body 1, wherein a ventilation pipe 2 and a combustion box 3 are arranged in the windowsill body 1, a first air inlet 4 is arranged on the side surface of the combustion box 3, an air guide pipe 5, a partition plate 6, a support column 7 and a tension device are arranged in the combustion box, the partition plate 6 is provided with a chute 8 and a limiting block 9, a slide block 10 is arranged in the chute 8, the support column 7 is slidably connected with the slide block 10, a fixing piece 11 for fixing mosquito-repellent incense is arranged at the upper end of the support column 7, a first reel 12 is arranged at the lower end of the support column 7, the first reel 12 is connected with the tension device through a pull rope 13, the limiting block 9 is positioned on the partition plate 6 at the tail end of the chute 8, the limiting block 9 is used for contacting with one end of burning mosquito-repellent incense and limiting the rotation of, the first air inlet 4 is connected with the second air inlet 14 through an air guide pipe 5, the ventilation pipe 2 is provided with a third air inlet 16 and a micropore 17, the third air inlet 16 is located above the second air inlet 14, and the micropore 17 is communicated with the upper surface of the windowsill body 1.

In the process of repelling mosquitoes, the mosquito-repellent incense is placed on the fixing piece 11 above the supporting column 7, and the fixing piece 11 is inserted into the slot opening in the middle of the mosquito-repellent incense. The mosquito incense is rotated, the pull rope 13 is wound on the first reel 12, and the support post 7 has the tendency of moving and rotating along the sliding groove 8 under the action of the pulling device. The mosquito incense is ignited after rotating for a plurality of circles, and the burning end of the mosquito incense is propped against the limiting block 9. The mosquito-repellent incense is continuously shortened during burning, and the outer diameter of the mosquito-repellent incense is continuously reduced. Because the pull rope 13 is wound on the first reel 12, the support column 7 is rotatably connected with the slide block 10, the slide block 10 slides in the sliding groove 8, and under the action of the pulling device, the mosquito-repellent incense has the tendency of rotating and moving towards the other end of the sliding groove 8 and the tendency of rotating. When the mosquito-repellent incense burns, one end of the mosquito-repellent incense burning always props against the limiting block 9 under the action of the pulling device, so that one end of the mosquito-repellent incense burning is always positioned above the second air inlet 14. Air enters from a first air inlet 4 of the combustion chamber, is blown to a second air inlet 14 through an air guide pipe 5 and is blown to one end of the mosquito-repellent incense combustion, smoke and smell generated by the mosquito-repellent incense combustion are blown to a third air inlet 16 on the ventilation pipe 2, and finally are emitted from micropores 17 of the ventilation pipe 2. The smoke and smell diffused are spread on the window to disperse the mosquitoes. The screen window does not need to be installed on the window, and the ventilation effect of the window is improved. Especially, be fit for miniature window and use, not only make the window keep good ventilation performance, simultaneously because window opening itself is little, the mosquito repellent effect is more obvious. One end of the mosquito-repellent incense which is ignited is always positioned above the second air inlet 14 and below the third air inlet 16, so that the mosquito-repellent incense can contact with fresh air, and the burning of the mosquito-repellent incense is ensured. The hot air of combustion flows upwards, ensuring that fumes and odours enter the ventilation tube 2 from the third air inlet 16. When wind exists, air enters from the first air inlet 4, reaches the second air inlet 14 through the air guide pipe 5 and then blows towards the combustion head of the mosquito-repellent incense, enters the third air inlet 16 along with the flowing inertia of the air, then enters the ventilation pipe 2, and finally comes out from the micropores 17 of the ventilation pipe 2 to form good air circulation, so that smoke and smell generated by combustion of the mosquito-repellent incense are distributed more uniformly on a windowsill, and the mosquito-repellent effect is better.

Specifically, the third air inlet 16 is located in the middle of the ventilation pipe 2, and the micropores 17 are uniformly distributed on the ventilation pipe 2. Air enters from the third air inlet 16 and then diffuses towards the two ends of the ventilation pipe 2, and the micropores 17 are uniformly distributed on the ventilation pipe 2, so that smoke and taste are uniformly diffused, and the mosquito repelling effect is better.

The windowsill body 1 is provided with a groove for accommodating the combustion box 3, and the combustion box 3 is inserted into the groove. The burning box 3 is taken out from the windowsill, so that the mosquito-repellent incense is convenient to replace. A waterproof cover is arranged above the micropore 17, so that rainwater can be prevented from being poured into the ventilation pipe 2.

Specifically, the limiting block 9 is L-shaped. The movement of the mosquito incense in two directions is limited, and the slipping is avoided. Specifically, a fixed pulley 15 is arranged on the partition plate 6 below the limiting block 9, and the pull rope 13 is wound around the fixed pulley 15, and then two ends of the pull rope are respectively connected with the first reel 12 and the second reel 22. The direction of the pull rope 13 is changed, so that the arrangement of the tension device is facilitated, and the tension device is conveniently arranged in the middle of the combustion box 3.

Example 2

Referring to fig. 1 to 4, the present embodiment is different from embodiment 1 in that the pulling device comprises a torsion spring 18, a cylinder 19, a cone 20 and a pulling rope 21, the cylinder 19 and the cone 20 are rotatably connected to the combustion box 3, the cylinder 19 is driven by the pulling rope 21 and the cone 20, the cone 20 is connected to the partition 6 by the torsion spring 18, a second reel 22 is disposed on the cylinder 19, and the first reel 12 is connected to the second reel 22 by a pulling rope 13.

The torsion spring 18 acts on the cone 20, the cone 20 rotates under the action of torsion, the cone 20 pulls the cylinder 19 to rotate through the traction rope 21 when rotating, the second reel 22 is arranged on the cylinder 19, and the first reel 12 is pulled when the second reel 22 rotates, so that the pulling effect of the pulling device on the first reel 12 is realized. During the rotation of the cone 20, that is, during the process of releasing the elastic force of the torsion spring 18, the deformation of the torsion spring 18 itself becomes smaller when releasing the elastic force, and the torque becomes smaller, but as the cone 20 rotates, the pulling rope 21 winds from the end with the larger diameter to the end with the smaller diameter on the cone 20, and the torque applied to the cone 20 by the pulling rope 21 becomes smaller. Since the torque of the torsion spring 18 is reduced and the torque of the traction rope 21 on the cone 20 is also reduced, the tension of the traction rope 21 on the cone 20 is not changed when the forces are balanced. The pulling force of haulage rope 21 is unchangeable for the pulling force of stay cord 13 is also unchangeable, ensures that the mosquito-repellent incense receives at the pulling force unchangeable of combustion in-process support column 7, avoids too big at the initial stage of burning torsion spring 18 torsion, causes the cracked problem of mosquito-repellent incense. When the torsion spring 18 is tightened, the support post 7 is rotated. The pull rope 13 is connected with the second reel 22 on the cylinder 19, and the cylinder 19 is connected with the cone 20 by the pull rope 21, so that the stability of the rope winding process is facilitated, and the rope winding dislocation is avoided.
