Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model baffler.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
Please refer to Fig. 1, Fig. 1 is the structural representation of the utility model baffler.Baffler described in the utility model comprises cylindrical shell 1, suction tude 2, suction tude 31, intervalve 32, steam outlet pipe 3, the first dividing plate 5 and second partition 6, the 3rd dividing plate 7, the 4th dividing plate 8 and the 5th dividing plate 9.
Described the first dividing plate 5 is divided into the first chamber 4, anechoic chamber 21, anechoic chamber 22, anechoic chamber 23, anechoic chamber 24 and vibration chamber 25 with second partition 6, the 3rd dividing plate 7, the 4th dividing plate 8 and the 5th dividing plate 9 by described cylindrical shell 1.
Described steam outlet pipe 3 is connected with described cylindrical shell 1 from the outlet side of described cylindrical shell 1 and extends to the first chamber 4 of baffler, and the supervisor of described suction tude 2 inserts described cylindrical shell 1 inside from the inlet end of cylindrical shell 1, and extends to the vibration chamber 25 of baffler.In 21Zhi anechoic chamber, anechoic chamber 24, interior setting all has looped pipeline 41 to described suction tude 2.
Described intervalve 32 extends to vibration chamber 25 from the first chamber 4, and the body of described intervalve 32 anechoic chamber 21, anechoic chamber 22, anechoic chamber 23,24 inside, anechoic chamber is all connected with looped pipeline 61.
Described suction tude 2 on the main stem of 24 inside, 22Zhi anechoic chamber, anechoic chamber, be provided with for control exhaust stream to the second solenoid valve 12, on the byroad of 24 inside, 22Zhi anechoic chamber, anechoic chamber, be provided with for control exhaust stream to the first solenoid valve 11.During described the first solenoid valve 11 closure, the second solenoid valve 12 is opened; When described the first solenoid valve 11 is opened, described the second solenoid valve 12 cuts out.
The supervisor of suction tude 31 inserts the inside of described cylindrical shell 1 from another inlet end of cylindrical shell 1, and extends to the anechoic chamber 24 of baffler.In 21Zhi anechoic chamber, described suction tude 31 anechoic chamber 23, be provided with looped pipeline 51, on the main pipeline of 23 inside, 21Zhi anechoic chamber, described suction tude 31 anechoic chamber, be provided with for control exhaust stream to the 4th solenoid valve 14, on the byroad of 23 inside, 21Zhi anechoic chamber, anechoic chamber, be provided with for control exhaust stream to the 3rd solenoid valve 13.During described the 3rd solenoid valve 13 closure, the 4th solenoid valve 14 is opened; When described the 3rd solenoid valve 13 is opened, described the 4th solenoid valve 14 cuts out.
Especially, the first magnetic switch 11 and the 3rd magnetic switch 13 in same anechoic chamber do not opened at one time.
Described suction tude 2, suction tude 31 offer some bloops with steam outlet pipe 3 on the body of described anechoic chamber 21, anechoic chamber 22, anechoic chamber 23,24 inside, anechoic chamber.In described anechoic chamber 21, anechoic chamber 22,24 inside, 23Yu anechoic chamber, anechoic chamber be filled with silencing cotton, increases the erasure effect of anechoic chamber.
In use, exhaust enters baffler inside by suction tude 2 and suction tude 31 to the utility model baffler.Because suction tude 2 and suction tude 31 supervisors' outlet is in different anechoic chambers, and the opening time of looped pipeline is poor if having time, therefore, the gas of discharging from suction tude 2 and suction tude 31, can there is not mutual interference effect, thereby avoid the gas that enters baffler inside from various inlet pipe because mutually interfering and produce abnormal sound, cause the new not good technical problem of noise producing erasure effect.
Baffler described in the utility model is higher in engine speed, when gas discharge capacity is larger, can close the solenoid valve 13 in suction tude 31, open the solenoid valve 14 on supervisor, in like manner, can close the solenoid valve 11 in suction tude 2, open the solenoid valve 12 on supervisor, make exhaust as much as possible by the anechoic chamber of baffler and the intervalve that passes through of growing as far as possible, farthest reduce noise.
When the rotating speed of motor is lower, gas discharge capacity hour, can selectively be opened the solenoid valve on looped pipeline baffler anechoic chamber in, closes the solenoid valve on the supervisor of correspondence in baffler.The gas that manual control is entered by suction tude 31 and suction tude 2 is in the quantity of the anechoic chamber of baffler process and the length of the hush pipe passing through.Avoid engine gas discharge capacity less, still pass through the noise reduction of a plurality of anechoic chambers, cause gas to be discharged and have some setbacks, affect the technical problem of engine power.
The utility model, by changing the first suction tude of baffler and the structure of the second suction tude, is controlled exhaust in the gas flow of baffler inside, and while avoiding two suction tude air inlet, the exhaust between various inlet pipe is interfered mutually, and the abnormal voice producing.And treat the gas flow of motor when the lower and high rotating speed air displacement of slow-speed of revolution air displacement is higher with a certain discrimination, thereby while avoiding motor with low speed rotation, still pass through a plurality of anechoic chambers, and compared with the noise reduction of long hush pipe, affect the output power of motor.
These are only mode of execution of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
