For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances. Example one:

[0043] Referring to Figures 1-5, the present invention is a noise reduction structure for intelligent garbage can, including base 1 and fan 2 arranged in base 1. The base 1 is provided with sound-absorbing material 3 for absorbing noise. The sound-absorbing material 3 has good effect on absorbing middle and high frequency sound, which can effectively absorb the noise of the air inlet, thereby reducing the overall noise value and improving the user experience. The sound-absorbing material 3 can be porous material such as sound-absorbing cotton. The installation of sound-absorbing material 3 on the base 1 can

[0044] Reduce the noise by 2-3 decibels.

[0045] Referring to Figure 3, the base 1 is provided with a mounting groove 11 for fixing the sound-absorbing material 3. The sound-absorbing material 3 can be detachably arranged in the mounting groove 11. The installation of the mounting groove 11 can facilitate the fixation of the sound-absorbing material 3 and the positioning and installation of the sound-absorbing material 3.

[0046] Referring to FIG. 2 and FIG. 3, the mounting groove 11 is provided with a protective cover 4 for detachable fixing of the sound-absorbing material 3. The protective cover 4 is arranged to fix the sound-absorbing material 3, so that the sound-absorbing material 3 is more convenient to install and remove, and the sound-absorbing material 3 is convenient to replace.

[0047] Referring to FIG. 4 and FIG. 5, the protective cover 4 is provided with a plurality of protective cover sound transmission holes 41. The protective cover sound transmission holes 41 arranged on the protective cover 4 can conveniently make the noise pass through the protective cover 4 into the microporous structure of the sound-absorbing material 3, so as to avoid the influence of the protective cover 4 on the noise transmission.

[0048] Referring to FIG. 2, the fan 2 is provided with a fan air inlet 21. The sound-absorbing material 3 is arranged opposite to the fan air inlet 21. The sound-absorbing material 3 is arranged opposite to the fan air inlet 21, which can better absorb the noise passing out of the fan air inlet 21.

[0049] Referring to FIG. 2, the sound-absorbing material 3 has a thickness of 1mm.

[0050] Referring to FIG. 2, the sound-absorbing material 3 is a porous structure. The porous structure is convenient for absorbing noise. The sound wave penetrates into the pores of the sound-absorbing material 3, and the pores are mostly open pores internally interconnected, which is subjected to air molecular friction and viscous resistance, and makes the fine fibers vibrate mechanically, so as to convert the sound energy into heat energy. The sound absorption coefficient of such porous sound-absorbing material generally gradually increases from low frequency to high frequency, so the sound absorption effect of high frequency and medium frequency sound is better. Embodiment two:

[0051] Referring to FIG. 6-9, the noise reduction structure for the intelligent garbage can comprises a base 1 and a fan 2 arranged in the base 1. The fan 2 is provided with a sound-absorbing material 3 for absorbing noise. The sound-absorbing material 3 has good sound-absorbing effect on medium and high frequency noise, can effectively absorb the noise of the air inlet, thereby reducing the overall noise value and improving the user experience. In this embodiment, the sound-absorbing material 3 is arranged on the fan 2, so that the sound-absorbing material 3 is closer to

[0052] the noise source fan 2, and the effect is better. The arrangement of the sound-absorbing material 3 on the fan 2 can reduce the noise by 2-3 decibels.

[0053] Referring to FIG. 6 and FIG. 7, the fan 2 is provided with a sound-absorbing cavity 22 for fixing the sound-absorbing material 3. The sound-absorbing material 3 is detachably arranged in the sound-absorbing cavity 22. The sound-absorbing cavity 22 cooperates with the sound-absorbing material 3, the noise enters the sound-absorbing cavity 22,

[0054] and repeatedly vibrates in the sound-absorbing cavity 22, converts the sound energy into mechanical energy, thereby reducing the noise,

[0055] The sound-absorbing material 3 can absorb a part of sound waves of a specific frequency, so that the noise reduction effect is better.

[0056] Referring to Figs. 6 and 7, the cover plate 5 is detachably arranged on the fan 2. The sound-absorbing cavity 22 is arranged in the cover plate 5. The sound-absorbing cavity 22 and the sound-absorbing material 3 are convenient to disassemble and maintain.

[0057] Referring to Figs. 6 and 7, the back plate 6 is arranged between the fan 2 and the cover plate 5. The back plate 6 is provided with a plurality of back plate sound-permeable micro-holes 61.

[0058] The cover plate 5 is convenient to detachably fix. The back plate sound-permeable micro-holes 61 are arranged to facilitate the noise of certain specific frequency to enter the sound-absorbing cavity 22 through the micro-holes and repeatedly vibrate in the sound-absorbing cavity 22, so as to convert the sound energy into mechanical energy, thereby reducing the noise. For the sound-absorbing material of the same sparsity, generally speaking, the thicker the thickness is, the better the sound-absorbing effect is.

[0059] Referring to Figure 6 and Figure 7 , the sound-absorbing material 3 is a porous structure. The porous structure is convenient to absorb noise. The sound waves penetrate into the pores of the sound-absorbing material 3, and the pores are mostly open pores internally interconnected, which are subjected to air molecular friction and viscous resistance, and make the fine fibers vibrate mechanically, so as to convert the sound energy into heat energy. The sound-absorbing coefficient of such porous sound-absorbing material generally gradually increases from low frequency to high frequency, so the sound absorption effect of high frequency and medium frequency sound is good. Example three:

[0060] Referring to Figs. 10 and 11, the noise reduction structure for the intelligent garbage can includes the base 1 and the fan 2 arranged in the base 1. The base 1 is provided with the sound-absorbing material 3 for absorbing noise. The porous structure of the sound-absorbing material 3 absorbs the medium-high frequency noise generated during the operation of the fan 2, which can effectively absorb the noise, thereby reducing the overall noise value and improving the user experience.

[0061] Referring to Figure 10 and Figure 11The base 1 is provided with a flow channel side wall 13 for fixing the fan 2. The sound absorbing material 3 is arranged on the flow channel side wall 13. The flow channel side wall 13 is arranged to facilitate fixing the sound absorbing material 3 and the fan 2, and is also used to connect the base air inlet and the fan air inlet, facilitating air intake of the fan 2 and preventing foreign matter and liquid from entering the fan 2 through the gap between the base 1 and the fan 2. The sound absorbing material 3 arranged on the flow channel side wall 13 can absorb the noise generated during operation of the fan 2 and the noise generated when the air flow enters the fan 2 from the base air inlet. The sound absorbing material can be cut into the required shape according to requirements. The sound absorbing material used in this embodiment is a regular long strip.

[0062] Referring to Figure 10 and Figure 11 , the sound absorbing material 3 has a thickness of 10 mm. For the same kind of sparse sound absorbing material, generally speaking, the thicker the sound absorbing material is, the better the sound absorbing effect is.

[0063] Referring to Figure 10 and Figure 11 , the sound absorbing material 3 has a porous structure. The porous structure facilitates absorption of noise. Sound waves penetrate into the pores of the sound absorbing material 3, and the pores are mostly open pores that are internally interconnected, and are subjected to air molecular friction and viscous resistance, and small fibers are mechanically vibrated, so that sound energy is converted into heat energy. The sound absorption coefficient of such porous sound absorbing material generally gradually increases from low frequency to high frequency, so the sound absorbing effect on high frequency and medium frequency sound is good.
