[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0032] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: an evaporation air cooler that is beneficial to reducing noise, including an air cooler body 1. A wind barrel 11 is fixedly connected to the top of the air cooler body 1 for discharging gas. A noise reduction mechanism is arranged outside the wind barrel 11 for reducing noise. The noise reduction mechanism includes two noise reduction components 2. The two noise reduction components 2 are jointly sleeved outside the wind barrel 11. Installation components 4 are arranged at the front and rear parts of the two noise reduction components 2 for cooperating with the fixation of the two noise reduction components 2. Two protection components 3 are jointly arranged on the upper parts of the two noise reduction components 2 and the number is two, for protecting the sound absorption sleeve 23 and the sound absorption cotton 24 in the outer shell 21.

[0033] As Figure 3 - Figure 5 shown, the noise reduction component 2 includes an outer shell 21 for protecting internal components and connecting various components. Galvanized iron meshes 22 are fixedly connected to the middle part of the inner wall of the outer shell 21 and the side close to the air duct for cooperating with the installation of the sound absorption sleeve 23 and the sound absorption cotton 24. A sound absorption sleeve 23 is movably connected between the outer shell 21 and the galvanized iron meshes 22 for sound absorption and noise reduction. A sound absorption cotton 24 is movably connected between the two galvanized iron meshes 22 for reducing noise.

[0034] Furthermore, a limiting groove 212 is opened in the upper part of the outer shell 21 for cooperating with the installation of the protection component 3 and for cooperating with the connection of the clamping block 33. A connection port 211 is opened in the middle of the top surface of the limiting groove 212 for cooperating with the insertion of the clamping block 33. The protection component 3 includes a clamping strip 31 for protecting the sound absorption sleeve 23 and the sound absorption cotton 24 in the outer shell 21. The two clamping strips 31 can form a ring, and the size of the ring is the same as the size of the openings on the two outer shells 21. Pulling rings 32 are fixedly connected to both ends of the top surface of the clamping strip 31 to facilitate the installation and rotation of the clamping strip 31. A clamping block 33 is fixedly connected to the middle of the clamping strip 31 for cooperating with the installation between the clamping strip 31 and the outer shell 21.

[0035] Furthermore, the installation component 4 includes a first connecting plate 41 for cooperating with the second connecting plate 42 to fix between the two noise reduction components 2. The first connecting plate 41 is fixedly connected to the housing 21 on the right side. The installation component 4 further includes a second connecting plate 42 for cooperating with the first connecting plate 41. The second connecting plate 42 is fixedly connected to the housing 21 on the left side. A bolt 43 is commonly threadedly connected between the first connecting plate 41 and the second connecting plate 42 for fixing between the first connecting plate 41 and the second connecting plate 42.

[0036] Specifically, a clamping plate 411 is fixedly connected to the upper part of the side of the first connecting plate 41 close to the second connecting plate 42 for temporarily limiting the position between the first connecting plate 41 and the second connecting plate 42. A limiting plate 412 is fixedly connected to the side of the clamping plate 411 close to the second connecting plate 42 for limiting the connection of the clamping plate 411. A clamping opening 421 is formed in the upper part of the second connecting plate 42 for cooperating with the connection of the clamping plate 411, and the clamping plate 411 is clamped thereto.

[0037] Working principle: When in use, first install the sound-absorbing sleeve 23 between the housing 21 and the galvanized iron net 22 in the middle, then install the sound-absorbing cotton 24 between the two galvanized iron nets 22, and then install the two noise reduction components 2 outside the air duct 11. When the two noise reduction components 2 are installed together, align the clamping plate 411 on the first connecting plate 41 with the clamping opening 421 on the second connecting plate 42, and insert the clamping plate 411 into the clamping opening 421. At this time, the limiting plate 412 will limit the clamping plate 411 to fix the first connecting plate 41 and the second connecting plate 42, so that the two noise reduction components 2 are connected together. Then fix the first connecting plate 41 and the second connecting plate 42 together through the bolt 43, so that the two noise reduction components 2 are fixed to the air duct 11. Then butt the two clamping strips 31 together to form a ring with the two clamping strips 31. Then align the clamping blocks 33 on the two clamping strips 31 with the connection ports 211 on the housing 21 respectively, push the clamping blocks 33 into the limiting grooves 212 through the connection ports 211, and then drive the two clamping strips 31 to rotate 90 degrees together through the pull ring 32 to make the clamping blocks 33 completely stuck with the limiting grooves 212, and the installation of the noise reduction mechanism can be completed. When it is necessary to replace the sound-absorbing cotton 24 or the sound-absorbing sleeve 23, just drive the clamping strip 31 to rotate again through the pull ring 32 to move the clamping block 33 to the connection port 211, and then pull out the clamping block 33 together with the clamping strip 31 from the connection port 211 out of the housing 21.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
