Embodiment one:

It as shown in Figure 1 and Figure 2, is the complete machine structure schematic diagram of the utility model embodiment one and silencing means structural representation Figure.A kind of soy bean milk making machine, including head 1 and cup body 2, the head 1 are buckled on the cup body 2, are provided with motor in the head 1 3, the 3 periphery suit silencing means 4 of motor, the silencing means 4 includes the second ring of the first annular plate 41 of internal layer, outer layer Silencing cavity 43 made of shape plate 42 and first annular plate and the second annular slab enclose, the first annular plate are equipped with multiple first Through-hole 411, the first through hole 411 are connected to silencing cavity 43.

The present embodiment reduces noise transmission intensity by being set with silencing means in motor periphery.The sound wave of noise passes through the When one through-hole, for sound wave because vibration generates friction in first through hole, sound can be converted into heat energy dissipation.The present embodiment is in the first ring Be provided with closure member above and below shape plate and the second annular slab, by internal layer and outer layer link together and with internal layer and outer layer A closed cavity is collectively formed, the sound wave after first through hole weakens enters silencing cavity, in noise reduction intracavity reflecting, decaying Silencing cavity is spread out of again, is substantially reduced by the noise of silencing means.

Specifically, second annular slab 42 is equipped with the second through-hole 421.Silencing means is that package is sleeved on the outer of motor Enclose, motor can generate a large amount of heat during the work time, therefore the heat dissipation problem of motor should be paid attention to, two pieces of annular slabs it is logical Hole can be radiated simultaneously with sound-deadening and noise-reducing.And sound wave, when passing through the second through-hole, sound wave and the second through-hole friction can convert sound At thermal energy, noise reduction, enters inside head via the sound wave after the second through-hole again, and acoustic wave segment and head lower cover collide, can be with Reflection and decaying many times is obtained, so that the noise of outflow head is greatly diminished.

Specifically, second through-hole 421 is shifted to install with the first through hole 411.Second through-hole is in addition to radiating also The sound of sound wave can be converted into the effect of thermal energy, but if first through hole is overlapped with the position of the second through-hole, for along vertical It directly can be directly pierced by from the second through-hole in the sound wave that the first perforated plate direction enters first through hole, i.e., the sound wave does not have in silencing cavity There are reflection and decaying, noise reduction effect will receive influence.Therefore shifted to install when second through-hole of the present embodiment and first through hole, make The sound wave obtained into silencing cavity sufficiently can reflect and decay.
