Embodiment 1

[0036] Such as figure 1 As shown, a noise reduction housing of the present invention has an inner cavity for accommodating a sound source, including

[0037] Outer shell 13;

[0038] The inner shell 12 is provided with at least one layer, and is arranged in the outer shell 13. At least one layer of the inner shell 12 is provided with a number of sound-absorbing holes, and one end port of the sound-absorbing hole facing inward The area is large, and the area of ​​the port facing outward is small. The sound-absorbing hole is designed as a structure with a large inside and a small outside, so that the sound from the sound source is directly transmitted to the inner shell 12, and is reflected or refracted through the sound-absorbing hole. During the transmission process, the sound source gradually decreases, forming the first Layer sound-absorbing structure. When the sound source passes through the inner shell 12, the outer shell 12 is designed to block and reflect each other, ...

Embodiment 2

[0043] A device equipped with a motor according to the present invention includes a motor 2 and a noise reduction housing 1 as described in Embodiment 1. The noise reduction housing 1 has an opening at one end and a shaft hole at the other end. The casing, the motor 2 is inserted into the inner cavity through the opening, and the motor shaft passes through the shaft hole. This can reduce the noise generated by the motor 2 running at high speed. There are various structures of the noise reduction housing 1. In this embodiment, preferably, the outer housing 13 includes a bottom, and an outer side wall arranged around the bottom on the bottom. The inner housing 12 In order to surround the inner wall on the bottom, the bottom is provided with a shaft hole, the other side of the noise reduction housing 1 opposite to the bottom forms the opening, and the sound-absorbing hole is set on the inner shell 12 . This can not only reduce the noise generated by the motor, but also dissipat...

Abstract

The invention provides a noise reduction housing and a device equipped with a motor. The noise reduction housing, having an inner cavity accommodating a sounding source, includes an outer layer housing and an inner layer housing. The inner layer housing is at least provided with one layer, and is arranged in the outer layer housing. The at least one layer of the inner layer housing is equipped with a plurality of noise reduction holes. The opening of one inward-facing end of each noise reduction hole has a large area, and the opening of the other outward-facing end of each noise reduction hole has a small area. The device equipped with a motor includes a motor, and is provided with the above noise reduction housing. One end of the noise reduction housing has an opening, and the other end of the noise reduction housing is provided with a casing with a shaft hole. The motor is inserted into the inner cavity through the opening, and a motor shaft passes through the shaft hole. The noise reduction housing has a great noise reduction effect, is simple in structure and low in cost, and helps to enhance heat dissipation effects of the motor when being used for the device equipped with the motor.

Description

technical field [0001] The invention relates to the field of noise reduction devices, in particular to a noise reduction housing and a device equipped with a motor. Background technique [0002] With the continuous improvement of the industry level, the market competition of cooking machine products is becoming increasingly fierce. Consumers have higher and higher requirements for cooking machines in the process of using products. The existing cooking machines include a shell, a motor installed in the shell, a motor cover set on the motor, and an impeller driven by the motor, etc. Because the motor cover of the existing cooking machine is only a common cover body, therefore, when the cooking machine is working, the noise generated when the motor inside the cooking machine rotates at a high speed cannot be obviously reduced, thereby reducing the user's good experience. [0003] Chinese patent document CN203147182U discloses a noise-reducing structure for a silent cover of a...
