[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The utility model provides an embodiment: an air-conditioning ventilation noise reduction structure, comprising a soundproof cover 1 and an air-conditioning body 3, the air-conditioning body 3 is arranged inside the soundproof cover 1, the bottom of the air-conditioning body 3 is fixedly connected with a support plate 4, the bottom four corners of the support plate 4 are fixedly connected with a fixed block 5, the left and right sides of the inside of the soundproof cover 1 are slidably connected with a silencer plate 6, the top of the silencer plate 6 is provided with two card slots 15, the top of the soundproof cover 1 is provided with two limit grooves 11 on the left and right sides, the inside of the limit groove 11 is fixedly connected with a spring 12, the other end of the spring 12 is fixedly connected with a limit block 13, the outside of the limit block 13 is fixedly connected with a card block 14, and the inside of the soundproof cover 1 is installed with a cleaning component 8.

[0026] Specifically, by placing the air-conditioning body 3 inside the soundproof cover 1, the noise generated during the operation and ventilation can be reduced, thereby reducing noise pollution. The air-conditioning body 3 can be fixed by the support plate 4 to avoid shaking during operation, thereby ensuring the stability of the structure. The fixing blocks 5 at the four corners of the bottom play a supporting role. At the same time, rubber pads are arranged around the fixing blocks 5 to reduce the noise generated by vibration and effectively achieve the effect of noise reduction. The sound-absorbing panels 6 on both sides of the air-conditioning body 3 can absorb the diffused noise, thereby reducing the noise of air-conditioning ventilation. By pulling the pull rod 7, the pull rope 10 can be driven to move, thereby making the limit blocks 13 connected to the two ends of the pull rope 10 slide inside the limit groove 11, and compressing the spring 12, thereby making the card block 14 disengage from the card groove 15. At this time, the sound-absorbing panel 6 can be taken out from the inside of the soundproof cover 1 by the handle 9, and then the operation of replacing the sound-absorbing panel 6 can be realized to prevent the sound-absorbing effect of the sound-absorbing panel 6 from decreasing after long-term use, resulting in the weakening of the noise reduction effect of the overall structure. At the same time, the card connection method is convenient for disassembly, and replacement is time-saving and labor-saving.

[0027] Reference Figure 4 The cleaning component 8 includes a motor 801, which is fixedly connected to the bottom of the sound insulation cover 1. The output end of the motor 801 is fixedly connected to a threaded rod 802, the external thread of the threaded rod 802 is connected to a threaded sleeve 803, and the external part of the threaded sleeve 803 is fixedly connected to a cleaning rod 804. A guide rod 806 is fixedly connected to one side of the interior of the sound insulation cover 1, and a slider 805 is slidably connected to the outside of the guide rod 806; the other end of the cleaning rod 804 is fixedly connected to the outside of the slider 805, and the surface of the cleaning rod 804 is in contact with the outer surface of the ventilation fence 2; the other end of the threaded rod 802 is rotatably connected to the inner top of the sound insulation cover 1.

[0028] Specifically, the motor 801 is fixed inside the soundproof cover 1 so that the motor 801 is stable and not prone to shaking during operation, thereby ensuring the operating effect of the structure. Then, the motor 801 drives the threaded rod 802 to rotate, thereby moving the threaded sleeve 803 and driving the cleaning rod 804 to move. At this time, the slider 805 slides along the guide rod 806 to guide the cleaning rod 804. The surface of the cleaning rod 804 is covered with a brush and is tightly attached to the surface of the ventilation bar 2, so that the ventilation bar 2 can be cleaned by the brush on the surface of the cleaning rod 804, reducing the accumulation of dust on the ventilation bar 2, thereby making the ventilation effect better, improving the smoothness of air flow, and avoiding more noise generated by the operation of the machine.

[0029] Reference Figure 2 , Figure 3 and Figure 5The front end of the soundproof cover 1 is fixedly connected with a ventilation fence 2, and the outside of the soundproof plate 6 is fixedly connected with a handle 9; one end of the limit block 13 is fixedly connected with a pull rope 10, and the top of the soundproof cover 1 is slidably connected with a pull rod 7, and the outside of the pull rope 10 is slidably connected to the inside of the pull rod 7; the outside of the spring 12 is slidably connected to the inside of the limit groove 11, and the outside of the limit block 13 is slidably connected to the inside of the limit groove 11; the longitudinal section of the clamping block 14 is set to be square, and the clamping block 14 and the clamping slot 15 are plug-in fit.

[0030] Specifically, the ventilation fence 2 can ensure smooth ventilation of the air conditioner and achieve a certain isolation effect. The handle 9 can be used to pull the silencer 6 to move it, so that it can be taken out of the soundproof cover 1 to achieve the replacement operation, which extends the service life of the device. The pull rope 10 can be driven to move by pulling the pull rod 7, so that the block 14 is disengaged from the slot 15, thereby completing the disassembly of the silencer 6. The spring 12 slides inside the limit slot 11, so that the spring 12 is restricted when moving, and pressure can be generated on it by the limit block 13 to make it shrink, and it can be restored after the pull rope 10 is loosened, so that the block 14 is inserted into the slot 15 to fix the silencer 6.

[0031] Working principle: When using this structure, the air conditioner body 3 is placed in the soundproof cover 1 and fixed by the support plate 4. At the same time, the four corners of the bottom of the support plate 4 are connected with fixing blocks 5 to support it. By installing silencer plates 6 on both sides of the air conditioner body 3, part of the noise generated during its operation can be absorbed, which has a certain noise reduction effect and reduces the negative impact of noise on the human body. By pulling the pull rod 7 and then driving the pull rope 10 to move, the limit blocks 13 connected to the two ends of the pull rope 10 slide inside the limit groove 11, thereby disengaging the card block 14 from the card groove 15, so that the silencer can be removed by the handle 9. The plate 6 is taken out from the inside of the soundproof cover 1 to realize the replacement operation, so as to prevent the sound absorption effect of the sound-absorbing plate 6 from decreasing after long-term use, thereby weakening the noise reduction effect. The motor 801 drives the threaded rod 802 to rotate, so that the threaded sleeve 803 moves, and at the same time drives the cleaning rod 804 to move. At this time, the slider 805 slides along the guide rod 806, which guides the cleaning rod 804, so that the ventilation fence 2 can be cleaned by the brush on the surface of the cleaning rod 804, so as to avoid excessive dust accumulation on its surface, which affects the ventilation volume and causes the noise generated during ventilation to increase, thereby affecting human health.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
