Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the first embodiment, as shown in fig. 1, 2 and 3, the present invention includes a cooler body 1, a ventilation opening 2 is connected to the upper end of the cooler body 1, a noise reduction assembly 3 is installed at the upper end of the ventilation opening 2, and moving wheels 15 are installed at four corners of the lower end of the cooler body 1;

the subassembly 3 of making an uproar falls including falling a noise section of

thick bamboo

4, 4 lower extremes of falling a noise section of thick bamboo of making an uproar is connected with clamping ring 5, clamping

ring

5 and 2 threaded connection of vent, 4 upper end threaded connection of falling a noise section of thick bamboo of making an uproar has

end cover

6, 4 inside downside of falling a noise section of thick bamboo of making an uproar is connected with

bottom plate

7, 7 top of bottom plate is connected with upper fixed plate 8, evenly be connected with air pipe 9 between upper fixed plate 8 and the bottom plate 7, air pipe 9 outside just is located to be filled between upper fixed plate 8 and the bottom plate 7 and has inhales the sound cotton 10, can absorb the noise reduction, 8 upper ends of upper fixed plate are connected with loudspeaker cover 11, air pipe 9 upper end is located inside loudspeaker cover 11, loudspeaker cover 11 upper end is connected with connecting pipe 12, connecting pipe 12 runs through and extends to 6 outsides to the end, connecting pipe 12 outer end upper portion is connected with retaining ring 13, connecting pipe 12 inner wall connection has filter screen 14, can avoid external impurity to get into.

Second embodiment, on the basis of first embodiment, air pipe 9 includes interior body 901, interior through-hole 902 has evenly been seted up to interior body 901 outer end, interior through-hole 902 is outside and be located the outside outer body 903 of cup jointing of interior body 901, outer through-hole 904 has evenly been seted up to outer body 903 outer end, it has sponge 905 to fill between interior body 901 and the outer body 903, can absorb the weakening to the noise, and interior body 901 inner wall cross connection has spoiler 906, can block the weakening to the noise, interior through-hole 902 is the low slope column structure setting in the outer height, make things convenient for sound to get into outside body 903 inside.

The working principle is as follows: when using, when the noise that cooling machine body 1 work produced is outwards transmitted by vent 2, the noise at first gets into the space below bottom plate 7 of falling the inside below of a section of thick bamboo 4 from vent 2, then get into inside ventilation pipe 9, when the noise gets into inside ventilation pipe 9, make sound by multistage blocking under spoiler 906's effect, then sound gets into outside pipe body 903 from interior through-hole 902 inside, because the setting of sponge 905, and sponge 905 is porous structure, the noise that gets into outside pipe body 903 inside can be further absorbed, then partial noise passes outside through-hole 904 and gets into and falls a section of thick bamboo 4 inside of falling, again absorb sound under the effect of inhaling sound cotton 10, thereby can make the noise that passes vent 2 absorbed, thereby reach the purpose that reduces the noise.
