At the same time, when the frequency conversion motor 13 drives the air intake fan blades 14 to transport the gas to the inside of the pig shed body 1, the volatilization speed of the insect repellent liquid on the sponge block 21 is automatically controlled through the cooperation of the air intake fan blades 14, the insect repellent cylinder 2 and the control component 3, that is, when the power of the frequency conversion motor 13 driving the air intake fan blades 14 is increased, the insect repellent liquid on the sponge block 21 evaporates faster, and when the power of the frequency conversion motor 13 driving the air intake fan blades 14 is reduced, the insect repellent liquid on the sponge block 21 evaporates slower, and through the cooperation of the insect repellent cylinder 2 and the cleaning brush 4, the cleaning brush 4 cleans mosquitoes and other debris on the air intake filter 15 in time.

[0027] like Figures 3 to 5 As shown, a through hole is provided on the side of the insect repellent cylinder 2, a control hole is provided on the control member 3, the control hole is connected with the through hole, a control block 31 is slidably provided inside the control hole, a control groove 32 is provided in a linear array on the control block 31, and a reset unit is provided between the control block 31 and the control member 3, so that when the power of the variable frequency motor 13 driving the fan blades 14 changes, the size of the connecting aperture of the control groove 32 is automatically controlled through the cooperation of the control member 3, the control block 31 and the reset unit, thereby automatically controlling the volatilization speed of the insect repellent liquid on the sponge block 21.

[0028] like Figures 3 to 5As shown, the reset unit includes a reset plate 33, a reset rod 34, a reset block 35 and a reset spring 36. A reset cavity is symmetrically provided on the control member 3. The reset plate 33 is symmetrically provided on the control block 31. One end of the reset rod 34 is provided on the reset plate 33, and the other end of the reset rod 34 is slidably provided inside the reset cavity. The reset block 35 is provided on the rod end of the reset rod 34 located inside the reset cavity. The reset spring 36 is provided between the reset block 35 and the inner wall of the reset cavity.

[0029] like Figure 3 and Figure 4 As shown, a first connecting seat 5 is provided at the center of the fan inlet blade 14, and a threaded groove is provided on the first connecting seat 5. A threaded rod 51 is provided at the center of the insect repellent barrel 2 close to the fan inlet blade 14, and the threaded rod 51 is rotatably connected to the threaded groove, so that the insect repellent barrel 2 rotates together with the fan inlet blade 14 through the cooperation of the first connecting seat 5 and the threaded rod 51.

[0030] like Figure 3 and Figure 4 As shown, a second connecting seat 6 is provided at the center of the side of the insect repellent cylinder 2 away from the fan blades 14, and a cross slot is provided on the second connecting seat 6. A connecting ring 61 is provided at the center of the air inlet filter 15. A connecting shaft 62 is provided inside the connecting ring 61 for rotation. A cross plug block 63 is provided at the center of the side of the connecting shaft 62 close to the insect repellent cylinder 2. The cross plug block 63 is slidably connected to the cross slot, and the connecting shaft 62 is transmission-connected to the cleaning brush 4. Therefore, through the cooperation of the second connecting seat 6, the connecting ring 61, the connecting shaft 62 and the cross plug block 63, the cleaning brush 4 rotates with the insect repellent cylinder 2, so that the cleaning brush 4 can timely clean mosquitoes and other debris on the air inlet filter 15.

[0031] like Figure 3 and Figure 4 As shown, the air inlet end of the air inlet fan 12 is provided with mounting grooves in a circumferential array, the outer side of the air inlet filter 15 is provided with a mounting ring 64, and the mounting ring 64 is provided with mounting blocks 65 in a circumferential array. The mounting blocks 65 are installed in the inside of the mounting groove by mounting bolts 66, so that the air inlet filter 15 can be quickly disassembled and assembled by the cooperation of the mounting ring 64, the mounting block 65 and the mounting bolts 66, so as to facilitate the replenishment of the sponge block 21 inside the repellent tube 2 with insect repellent liquid.

[0032] like Figure 3 and Figure 4As shown, a mounting shaft 67 is provided at the center of the connecting shaft 62 away from the insect repellent cylinder 2, and the cleaning brush 4 is provided on the mounting shaft 67, so that the cleaning brush 4 rotates together with the insect repellent cylinder 2 through the cooperation on the connecting shaft 62 and the mounting shaft 67, so that the cleaning brush 4 can clean mosquitoes and other debris on the air inlet filter 15 in time.

[0033] Working principle: When the pig shed 1 is ventilated by the cooperation of the exhaust fan 11 and the air inlet fan 12, the variable frequency motor 13 inside the air inlet fan 12 will drive the air inlet fan blades 14 to transport the gas to the inside of the pig shed 1. At this time, the first connecting seat 5 connected to the air inlet fan blades 14 will drive the insect repellent cylinder 2 connected to the threaded rod 51 to rotate, and the insect repellent cylinder 2 will drive the control member 3 to rotate when it rotates. When the control member 3 rotates, the control block 31 will slide in the direction away from the control member 3 under the action of centrifugal force. When the control block 31 slides in the direction away from the control member 3, it will drive the control slot 32 to slide in the direction away from the control hole on the control member 3, so that the control hole on the control member 3 passes through the control slot 3. 2 is connected with the outside world, and then the through hole on the insect repellent cylinder 2 is connected with the outside world through the control hole and the control groove 32 on the control member 3. At this time, the insect repellent liquid on the sponge block 21 evaporates to the inside of the air inlet fan 12 through the through hole on the insect repellent cylinder 2, the control hole and the control groove 32 on the control member 3. At the same time, the airflow generated by the air inlet fan blades 14 driven by the variable frequency motor 13 is transported to the inside of the pig shed body 1. When the insect repellent cylinder 2 rotates, it will also drive the cross plug block 63 connected to the second connecting seat 6 to rotate. When the cross plug block 63 rotates, it will drive the installation shaft 67 connected to the connecting shaft 62 to rotate. When the installation shaft 67 rotates, it will drive the cleaning brush 4 to clean mosquitoes and other debris on the air inlet filter 15 in time.

[0034] When it is necessary to improve the ventilation effect of the pig shed 1, the power of the variable frequency motor 13 driving the fan blades 14 is increased, so that the rotation speed of the fan blades 14 is accelerated. When the rotation speed of the fan blades 14 is accelerated, the rotation speed of the insect repellent barrel 2 will also be accelerated. When the rotation speed of the insect repellent barrel 2 is accelerated, the control block 31 will slide a farther distance away from the control member 3 under the action of centrifugal force, thereby increasing the connecting aperture of the control groove 32, so that the insect repellent on the sponge block 21 evaporates faster, and at the same time further improves the effect of the cleaning brush 4 on cleaning mosquitoes and other debris on the air inlet filter 15.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
