There is spiral shape water guide sector, spiral shape water guide sector is arranged between cylinder 1 and downcomer 11, and flowing water is led in the spiral shape water guide sector
To the inner wall of downcomer 11.
During use, the water flow to fall in downcomer 11 is when spiral shape water guide sector is flowed, helically formula
Water is got rid of the inner wall to downcomer 11 by the centrifugal force of rotational flow, generation, is allowed the water to flow down along the inner wall of downcomer 11, effectively be subtracted
Few huge noise caused by water falls vertically under the effect of gravity.
A kind of specific embodiment as above-mentioned technical proposal, the spiral shape water guide sector include that several do not connect each other
Continuous spiral weather board 2, several described spiral weather boards 2 equidistantly around distribution and are fixed on institute around the axis of the cylinder 1
On the outer wall for stating cylinder 1, spiral weather board 2 is abutted far from the side of the cylinder 1 with the inner wall of downcomer 11.
When the water in fish jar enters downcomer 11 from the upper end of downcomer 11, water flow can directly with spiral weather board 2
Surface contacts and in the surface flow of spiral weather board 2, and when flowing along spiral weather board 2, water flow generates centrifugal force, makes water flow
The inner wall to the downcomer 11 abutted with spiral weather board 2 is got rid of, so that water flow is adsorbed on inner wall and is flowed along inner wall, effectively reaches
The effect of noise reduction.
As a kind of preferred embodiment to above-described embodiment, the spiral weather board 2 includes the torsion of spiral setting
Bent plate, one end of the twisted board is to the other end in reverse twist.Water flow is distorting when flowing on spiral weather board 2
Under the action of plate, keep the speed of water flow different on spiral weather board 2, effectively guides water fluid flow.
In this embodiment, preferably, the spiral water guide sector further includes the rib 3 that the outer wall of cylinder 1 is arranged in,
Baffle 9 is connected between rib 3 and spiral weather board 2, baffle 9 extends to the top of rib 3 from the top of spiral weather board 2,
Form apopore 4 between two neighboring baffle 9, form collector nozzle 8 between the lower end of the lower end barrel of rib 3, collector nozzle 8 with
Apopore 4 is connected to.
Water toward it is dirty when under the action of baffle 9, so that water flow is accurately dropped on spiral weather board 2, in water pump
When power is small, also the lesser water flow of dropping velocity can effectively be enable to flow on spiral weather board 2.
Preferably, in above-described embodiment, the cylinder 1 is additionally provided with placement circle, and the placement circle is arranged in the baffle 9
Outside, the placement circle are placed on the downcomer 11.Preferably, it places circle to be integrally formed with baffle 9, improves baffle 9, rib
3 and spiral weather board 2 intensity, meanwhile, be placed on the top of downcomer 11 by the way that circle will be placed, facilitate installation.
Preferably, in one embodiment, the inner wall of the cylinder 1 is provided with several protrusions 5 abutted with inner tube 10,
The respiratory slot 6 flowed for air is formed between adjacent protrusion 5, the respiratory slot 6 extends to its bottom from the top of cylinder 1 and passes through
Wear the cylinder 1.Due to water flow can spiral flow when it is unavoidable will form turbulent flow, if the inner wall of cylinder 1 with it is interior
The outer wall of pipe 10 directly abuts, then can generate great aerial respiration sound, cause noise, by by 1 set of cylinder in inner tube 10
When, abutting protrusion 5 with inner tube 10 makes to form the respiratory slot 6 flowed for air between the inner cavity of cylinder 1 and the outer wall of inner tube 10,
During draining, respiratory slot 6 plays respiration to air, effectively improves air circulation effect, air is discharged, effectively
Reduce the noise that air generates.
In turn, it is preferable that referring to Fig.1, the length of the rib 3 is adjustable, during actual use, due to water pump function
The size of rate can make the speed of water flow different, when water flow enters from apopore 4 to be come out from collector nozzle 8, if from being lauched
The water velocity of mouth 8 is less than the speed of water inlet, and it will cause water accumulations, and water is caused to form turbulent flow, generates noise, passes through adjusting
The length of rib 3 can make the width of collector nozzle 8 so as to adjust the water velocity of collector nozzle 8, it is made to cooperate the water pump of different capacity
Water speed, thus adjust adjust apopore 4 on water level conditions, prevent water level do not had cylinder 1 top even respiratory slot 6 is flooded
Not yet, muffler is made to fail.As an implementation, in the present embodiment, the fin 3 is processed and formed at one time, in practical work
When making, user can as needed be cut fin 3, be used cooperatively it.
Preferably, the top of the cylinder 1 is additionally provided with several ventilation ports 7, and the ventilation port 7 is connected to respiratory slot 6,
The setting of several ventilation ports 7 interval.During installation, the upper end of inner tube 10 will be connected with water pipe head 13, water pipe head
13 bottom end has certain probability that can abut with the top of muffler during cooperation, so that the respiratory slot 6 of silencer be made to close
It closes, the effect of air-breathing cannot be generated, therefore, several ventilation ports 7 are set on the top of cylinder 1, so that respiratory slot 6 is passed through
Ventilation port 7 is connected to outside air, reaches the function of air-breathing, to guarantee to reach erasure effect.
In the present embodiment, a kind of preferred improved procedure, the ventilation port 7 are higher than the top of the spiral shape water guide sector
Water flow when there be not the bottom of ventilation port 7 when water level is excessively high, can be flowed out by ventilation port 7 from ventilation port 7, prevent water level by portion
Continue to rise to close all respiratory slots 6.
Referring to Fig. 2 and Fig. 3, a kind of discharge structure, including inner tube 10, muffler, downcomer 11 and outer tube 12 are described to disappear
Sound device is set in inner tube 10, and downcomer 11 is set in outside muffler, and the spiral shape water guide sector of muffler is interior with downcomer 11
Wall abuts, and outer tube 12 is set in outside downcomer 11.Water flows downward from downcomer 11, adsorbs water flow by spiral shape water guide sector
On the inner wall of downcomer 11, effectively reduce since generated noise is flowed in natural disorder to water flow under the effect of gravity.
Preferably, water pipe head 13 is connected in said inner tube 10, the bottom of water pipe head 13 is far from the muffler
Top.It prevents the bottom of water pipe head 13 from blocking the air-permeating hole 6 in cylinder 1, sound deadening is effectively ensured.
Preferably, the top of the outer tube 12 is equipped with protective cover 14, and it is ventilative that several are provided on the protective cover 14
