Embodiment 2:
As shown in figure 4, present embodiments providing another wall-breaking machine noise reduction cup lid 200, the difference with embodiment 1 exists
In increasing conically shaped 210 and priming apparatus 230.
Conically shaped 210 includes big end and small end, and big end is connect with the free end of inner cylinder 1212；On the barrel of conically shaped 210
It is provided with through-hole；Priming apparatus 230 is for adding water to accommodating space 1214 automatically, to form water seal.
Such as Fig. 5, priming apparatus 230 includes adding water box 234, first connecting rod 231, second connecting rod 232, third connecting rod 233, rubber
The edge of film 236 and priming valve door 235, sheet rubber 236 is connect with conically shaped 210；And sheet rubber 236 is to conically shaped 210
Inner recess.One end of first connecting rod 231 is connect with the middle part of sheet rubber 236, the other end and second connecting rod of first connecting rod 231
232 is hinged, and the free end of second connecting rod 232 and third connecting rod 233 are hinged, the free end of third connecting rod 233 and priming valve door 235

Stifled, sheet rubber 236 can be opened baffle by first connecting rod 231, second connecting rod 232 and third connecting rod 233.
The working principle of wall-breaking machine noise reduction cup lid 200 provided in this embodiment with it is substantially similar in embodiment 1.Specifically,
When fluid temperature (F.T.) is lower in cup body 410, when the steam in cup body 410 is fewer, steam is difficult to condense in accommodating space 1214
It is gathered into water seal.At this point, high-frequency noises pass through conically shaped after using the 400 noise reduction cup lid 200 of wall-breaking machine in the present embodiment
When 210, energy is focused into small end, and then passes to sheet rubber 236, and noise drives sheet rubber 236 to move, sheet rubber 236

It is dynamic, water seal is formed so as to which the water added in water box 234 releasing to be flowed into accommodating space 1214.
In addition, since sheet rubber 236 uses there is certain thickness rubber slab to be made into, therefore its vibration will not bring and make an uproar
Sound.Again since sheet rubber 236 is to lower recess, therefore the noise of medium-high frequency is more easier to drive up sheet rubber 236, to open
Priming valve door 235.Also, due to being provided with through-hole on the barrel of conically shaped 210, steam and partial noise can also pass through taper
Micropore on cylinder 210 travels to the external world, and this prevent confined space is formed in cup body, noise and steam, which have little time outflow, to be caused
Noise and steam reverberate resonance in confined space.
