[0022] 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.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a loudspeaker with an insect-proof structure, comprising a base 1, a sound tube 2, and a protective cover 5. The sound tube 2 is mounted on the top of the base 1, and the outer wall of the sound tube 2 is provided with sound holes 3. Several sound holes 3 are arranged in a ring on the outer wall of the sound tube 2. A loudspeaker 4 is mounted at the center of the top of the base 1. The protective cover 5 is provided on the outer side of the sound tube 2, and an insect-proof component is provided on the right side of the protective cover 5. The insect-proof component includes an insertion hole 6, a medicine cartridge 7, an insect repellent paste 8, a volatilization tank 9, a bellows 10, a wind chamber 11, a fan 12, an air inlet 13, and a through groove 14. The top right side of the protective cover 5 is provided with an insertion hole 6, and a medicine cartridge 7 is provided inside the insertion hole 6. The insertion hole 6 is provided with internal threads, and the surface of the medicine cartridge 7 is provided with external threads. The medicine cartridge 7 is provided with insect repellent paste 8. The outer side wall of the medicine cartridge 7 is provided with a volatilization groove 9. The top of the protective cover 5 is equipped with a bellows 10, and the bellows 10 is provided with an air chamber 11. The air chamber 11 is equipped with a fan 12. The top of the air chamber 11 is provided with an air inlet 13. Several air inlets 13 are provided at the top of the air chamber 11. The several air inlets 13 are symmetrically distributed. The bottom of the air chamber 11 is provided with a through groove 14.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, when in use, the cartridge 7 is inserted into the insertion hole 6 on the outer wall of the protective cover 5 and fixed by the thread. The insect repellent paste 8 inside the cartridge 7 can evaporate outward along the evaporation groove 9 and disperse along the sound hole 3, which can assist in insect repellent treatment. If the fan 12 is turned on, the airflow can be accelerated to enter the protective cover 5 and the inner side of the sound tube 2 along the air inlet hole 13 and the through groove 14, and then discharged along the sound hole 3. During this process, the evaporation of the insect repellent paste 8 can be accelerated. Insect repellent treatment is carried out through the airflow and the insect repellent paste 8.

[0025] The top of the inside of the sound tube 2 is provided with a mounting bracket 16, a reinforcing rod 17 is fixed to the outer wall of the mounting bracket 16, and an electric push rod 15 is installed at the top of the mounting bracket 16. The top of the electric push rod 15 is fixedly connected to the top of the inside of the protective cover 5.

[0026] Specifically, such as Figure 1 As shown, when in use, when the electric push rod 15 is extended, the protective cover 5 can be pushed to move upward along the sound tube 2. During this process, the sound hole 3 on the surface of the sound tube 2 is exposed, and the horn can be used. Conversely, when the horn is not needed, the electric push rod 15 can be extended. At this time, the protective cover 5 can be driven to move downward. The protective cover 5 covers the outside of the sound tube 2, which can prevent foreign objects from entering the interior of the device through the sound hole 3.

[0027] An insert 18 is provided on the outer side of the base 1. A mounting base 19 is fixed at the bottom end of the insert 18. A mounting hole 20 is provided on the top surface of the mounting base 19. A locking hole 21 is provided on the right side of the insert 18. A locking bolt 22 is provided inside the locking hole 21.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, in use, first install the mounting base 19. The mounting holes 20 on the surface of the mounting base 19 are matched with screws and other accessories to complete the installation of the mounting base 19. Then, the base 1 can be inserted into the insert 18 on the surface of the mounting base 19. Tighten the locking bolt 22 on the side end, which is pressed against the surface of the base 1 to help fix the base 1 inside the insert 18 and complete the installation. Conversely, tighten the locking bolt 22 until it is loose, and after loosening the fixation of the base 1, the base 1 can be pulled out from the inside of the insert 18 to complete the disassembly of the speaker.

[0029] Working principle: In use, first install the mounting base 19. The surface of the mounting base 19 has multiple sets of mounting holes 20. The mounting holes 20 cooperate with screws and other anchors to fix it in place where it is needed. Then, directly insert the base 1 into the insert 18 on the surface of the mounting base 19 and tighten the locking bolt 22 on the side to secure it. Insert the cartridge 7 through the insert 6 on the outside of the protective cover 5. Rotate the cartridge 7 to install it via the thread. Activate the electric push rod 15 to extend, pushing the protective cover 5 upwards along the sound tube 2, exposing the sound hole 3. The sound can then be used. During this process, the insect repellent inside the cartridge 7... The paste 8 can evaporate outward along the evaporation groove 9 and drift along the sound hole 3, which can assist in insect repellent treatment. If the fan 12 is started, the airflow can be accelerated to enter the protective cover 5 and the inner side of the sound tube 2 through the air inlet 13 and the through groove 14, and then be discharged through the sound hole 3. During this process, the evaporation of the insect repellent paste 8 can be accelerated. While the insect repellent treatment is carried out through the airflow and the insect repellent paste 8, heat dissipation can also be assisted. If the horn is not needed, the electric push rod 15 can be directly started to shorten, and the protective cover 5 can be moved down and reset to cover the outside of the sound tube 2, which can prevent foreign objects from entering the interior of the device through the sound hole 3 and protect the device.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
