Embodiment 1

[0044] refer to Figure 1-5 , the present invention is a noise-reducing structure for an intelligent trash can, comprising a base 1 and a fan 2 disposed in the base 1 . The base 1 is provided with a sound-absorbing material 3 for absorbing noise. The sound-absorbing material 3 has a good sound-absorbing effect on medium and high frequencies, and can effectively absorb the noise of the air suction port, thereby reducing the overall noise value and improving user experience. The sound-absorbing material 3 can be porous materials such as sound-absorbing cotton. Installing the sound-absorbing material 3 on the base 1 can reduce the noise by 2-3 decibels.

[0045] refer to image 3 , The base 1 is provided with an installation groove 11 for fixing the sound-absorbing material 3 . The sound-absorbing material 3 is detachably arranged in the installation groove 11 . Setting the installation groove 11 can facilitate the fixing of the sound-absorbing material 3 and facilitate the ...

Embodiment 2

[0052] refer to Figure 6-9 , the present invention is a noise-reducing structure for an intelligent trash can, comprising a base 1 and a fan 2 disposed in the base 1 . The fan 2 is provided with a sound-absorbing material 3 for absorbing noise. The sound-absorbing material 3 has a good sound-absorbing effect on medium and high-frequency noise, and can effectively absorb the noise from the air suction port, thereby reducing the overall noise value and improving 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 the noise source fan 2, and the de-drying effect is better. The fan 2 is provided with the sound-absorbing material 3, which can reduce the noise by 2-3 decibels.

[0053] refer to Image 6 with Figure 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-a...

Embodiment 3

[0058] refer to Figure 10 with Figure 11 , the present invention is a noise-reducing structure for an intelligent trash can, comprising a base 1 and a fan 2 disposed in the base 1 . The base 1 is provided with a sound-absorbing material 3 for absorbing noise. The porous structure of the sound-absorbing material 3 absorbs the medium and high-frequency noise generated during the operation of the fan 2, and can effectively absorb the noise, thereby reducing the overall noise value and improving user experience.

[0059] refer to Figure 10 with Figure 11 , the base 1 is provided with a channel side wall 13 for fixing the fan 2 . The sound-absorbing material 3 is disposed on the sidewall 13 of the flow channel. The side wall 13 of the flow channel is convenient for fixing the sound-absorbing material 3 and the fan 2. The side wall 13 of the flow channel is also used to connect the air suction port of the base and the air inlet of the fan, so as to facilitate the air intake...

Abstract

The invention discloses a noise reduction structure for an intelligent trash can and the intelligent garbage can with the noise reduction structure. The noise reduction structure comprises a base and a draught fan arranged in the base and further comprises a porous sound absorption material arranged on the base or the draught fan and used for absorbing noise, and an installation groove used for fixing the porous sound absorption material is formed in the base. The porous sound absorption material is detachably arranged in the installation groove. Firstly, the porous sound absorption material is arranged in the base, and therefore the noise of an air suction port of the draught fan can be effectively absorbed; secondly, the draught fan is provided with the porous sound absorption material and a sound absorption cavity, noise with certain specific frequencies enters the cavity through micropores, sound energy is converted into mechanical energy through repeated oscillation, and the noise is reduced; thirdly, the noise in the operation process of the draught fan can be effectively absorbed and can be reduced to 66 decibels or below at most; and fourthly, the draught fan is arranged below a closed area, and the situation that due to the fact that liquid falls into the draught fan through a base air suction port, electronic components in the draught fan and the trash can are damaged by damp is prevented.

Description

【Technical field】 [0001] The invention relates to the technical field of fans, in particular to the technical field of noise reduction fans. 【Background technique】 [0002] Existing smart trash cans realize the bag spreading by fan rotating to form a negative pressure area near the suction port and drag the garbage bags to cover the body of the trash can. The trash can uses the static pressure provided by the fan to drag the garbage bags to the trash can Inside. When the static pressure of the fan is too large and the air volume is small, the working condition of the fan is relatively bad at this time, the speed is high, and the air volume is small, so the eddy current noise is relatively large, and the noise value at this time is relatively high, which can reach more than 72 decibels at most. The noise is more obvious when in use. However, there is no special de-drying mechanism in the existing fan, so that the noise of the existing fan is relatively high during operation...
