Description

The denoising structure of food refuse disposer

Technical field

The utility model is related to a kind of food refuse disposer, the denoising structure of specifically a kind of food refuse disposer.

Background technology

Currently, general food refuse disposer is divided into two classes on the market, one kind be direct current generator driving, it is another kind of be friendship Galvanic electricity machine drives, and most intuitively difference lies in the sizes of noise for both type of drive.In general DC motor speed is fast, empty Carrying Row noise is big but processing speed is fast compared with alternating current generator, AC machine rotating speed is slow, and no-load running low noise still handles speed It spends relatively slow.Although DC generator processing speed is fast, with the rotation of motor high speed, food refuse is in grinding system high speed The noise for colliding generation is not also small, and the size of noise directly affects user experience.

Such as a kind of Chinese patent literature CN103938682A food refuse disposers disclosed in 23 days July in 2014, Include apparatus main body and rotor, apparatus main body includes processing chamber, and rotor includes armature spindle, and armature spindle is rotationally inserted in In processing chamber, further include：Cross cutter, grinding cutter head, grinding segment, fine gtinding disk, fine gtinding disk are set to grinding cutter head Downside, offer third mounting hole on fine gtinding disk, armature spindle can be inserted on third mounting hole, be opened on fine gtinding disk Equipped with multiple diameters hole is penetrated no more than 1.5mm.The patent has drawbacks described above, is asked in the process of running without solving noise Topic.

Therefore, it is further improved.

Utility model content

The purpose of the utility model is to provide simple and reasonable, easy to use, securely and reliably, noise reduction is apparent The denoising structure of food refuse disposer, to overcome deficiency in the prior art.

By a kind of denoising structure of food refuse disposer of this purpose design, including crushing chamber ontology and grinding system, It is characterized in that：The crushing chamber ontology is formed by fixedly connecting by upper crushing chamber and lower crushing chamber；The upper crushing chamber is under Sealing ring is equipped between crushing chamber；The grinding system is located in lower crushing chamber；It is provided in the upper and lower crushing chamber side wall Several sound insulation cavitys.

The sound insulation cavity is divided into sound insulation cavity A and sound insulation cavity B；The sound insulation cavity A is along side wall ring around upper powder Broken chamber setting；The sound insulation cavity B is arranged along side wall ring around lower crushing chamber.

Sound insulation cavity A the radially extending along upper crushing chamber；The sound insulation cavity B prolongs along the radial direction of lower crushing chamber It stretches；The sound insulation cavity A and sound insulation cavity B is rectangular cavity；By thin-walled phase between each sound insulation cavity A/B Every.

Each sound insulation cavity A and opposite sound insulation cavity B is aligned and connects, and forms airtight chamber；The sound insulation cavity B's Sectional area is more than the sectional area of sound insulation cavity A.

The walled thickness is greater than or equal to 2mm.

Sound insulation by filling material in the sound insulation cavity A and sound insulation cavity B.

The upper and lower crushing chamber is cylindrical shape；The upper crushing chamber is fixed on by screw in lower crushing chamber, and by Lower crushing chamber surrounds；The sealing ring interference is connected between upper and lower crushing chamber.

The upper crushing chamber is made of enhancing nylon and glass fibre；The lower crushing chamber is by glass fiber reinforcement warm Solidity plastics BMC is made.

Sound insulation cavity in the utility model in upper and lower crushing chamber changes the medium of noise transmission, and noise passes through sound insulation The inside side walls of cavity enter in sound insulation cavity, using outside side wall, there is decaying to a certain extent；And in sound insulation sky Sound insulation by filling material in chamber can make effect more notable.Acoustic material is located in airtight chamber, will not be made by external action Use long lifespan.Upper and lower crushing chamber is glass fibre material, high mechanical strength, heat-resist.
