In specific embodiments more of the present invention, as depicted in figs. 1 and 2, silencing apparatus 100 also comprises warn device 7, and warn device 7 is electrically connected with detection device 6, and warn device 7 sends alert messages by according to the testing result of detection device 6.Thus, user can judge whether to need to open outlet 201 to get rid of the liquid in noise elimination cavity 2 according to alert messages, thus hydrops can be got rid of in time, completely.
Particularly, as depicted in figs. 1 and 2, warn device 7 comprises display device 71, and display device 71 is electrically connected with detection device 6 testing result showing detection device 6, and wherein, the testing result that display device 71 shows is the alert messages that above-mentioned warn device 7 sends.Thus, user can observe alert messages in time.
Wherein, display device 71 can show the amount of liquid in noise elimination cavity 2, and wherein, display device 71 can be various types of parts with Presentation Function, does not do concrete restriction here.Such as, display device 71 can be LED, and LED shows amount of liquid, when amount of liquid is lower than predetermined value with different colors, LED is shown in green, and when amount of liquid meets or exceeds this predetermined value, LED is shown in red, thus, display device 71 structure is simple, with low cost.Again such as, display device 71 can be the display device that can show amount of liquid in digital form, wherein, when there is not hydrops in noise elimination cavity 2, display device 71 is shown as " 0 ", when amount of liquid reaches predetermined value, display device 71 is shown as " 100 ", and thus, user can understand the actual liquid amount in noise elimination cavity 2 at any time.Here the predetermined value hydrops referred in noise elimination cavity 2 needs amount of liquid when getting rid of, and predetermined value is specifically set by practical situations, is not construed as limiting here.
Further, as shown in Figure 1, warn device 7 also comprises alarm 72, and alarm 72 is connected when reaching predetermined value with the testing result detected at detection device 6 with detection device 6, alarm 72 is reported to the police.Here, the mode that alarm 72 is reported to the police is the alert messages that above-mentioned warn device 7 sends.Thus, alert messages directly, effectively can be conveyed to user.
Alternatively, alarm 72 can be buzzer, and when amount of liquid reaches predetermined value, buzzer sounds.Certainly, alarm 72 is not limited to buzzer, and such as alarm 72 also can be flashing lamp etc.
Advantageously, warn device 7 is suitable for being arranged in cockpit, thus is convenient to user and obtains alert messages in time.Certainly, the mounting point of warn device 7 is not limited thereto, and such as, when warn device 7 is buzzer, warn device 7 is suitable for any position being fixed on automobile.
In one particular embodiment of the present invention, detection device 6 is inductive type pressure transducer 61.Thus, detection device 6 cost is not high, install easily, and testing result can be converted to electrical signal output by inductive type pressure transducer 61, thus be convenient to the transmission of Detection Information, process, storage, display, record and control etc., and then realize automatic detection and the automatic control function of silencing apparatus 100.
Particularly, inductive type pressure transducer 61 has dynamometry end face, and dynamometry end face extend in shell 1, and dynamometry end face directly can contact with the liquid converged in shell 1.When amount of liquid changes, the hydraulic pressure that hydrops is applied to dynamometry end face also can change.Inductive type pressure transducer 61 can detect the pressure change on dynamometry end face, and pressure signal is converted to electrical signal output.
Alternatively, inductive type pressure transducer 61 is fixed on the outer side wall of shell 1, thus facilitates installation and the replacing of inductive type pressure transducer 61.Wherein, shell 1 is provided with perforate (scheming not shown), and the dynamometry end face of inductive type pressure transducer 61 through perforate, and stretches in shell 1 and contacts with hydrops.
Wherein, inductive type pressure transducer 61 make use of Wheatstone bridge principle.Specifically, when hydrops in noise elimination cavity 2 is less and when cannot contact with inductive type pressure transducer 61, dynamometry end face is stressed is 0, and the electric bridge of inductive type pressure transducer 61 inside is in state of equilibrium, inductive type pressure transducer 61 Non voltage output.When hydrops increase and with dynamometry end contact after, the stressed of dynamometry end face changes, and the bridge balance of inductive type pressure transducer 61 inside is broken, and now has voltage to export.
More specifically, as shown in Figure 3, the signal that inductive type pressure transducer 61 exports is analogue signal, and the value of electrical signals exported is directly proportional to the amount of force that hydrops applies.When amount of liquid reaches predetermined value, the value of electrical signals that inductive type pressure transducer 61 exports is maximum, and now, warn device 7 sends alert messages.
In other embodiments of the present invention, as shown in Figure 1, counterpart 9 is bolt 91, now, outlet 201 is formed as tapped hole, when warn device 7 sends alert messages, user directly can back out bolt 91 and discharge hydrops to open outlet 201, after hydrops is discharged completely, again bolt is installed back original position.Thus make shell 1 and counterpart 9 structure simply, with low cost, and the process opened with close of outlet 201 is simple, easy.
In specific embodiments more of the present invention, as depicted in figs. 1 and 2, shell 1 comprises the first housing 11 and the second housing 12, suction tude 3 and steam outlet pipe 4 extend in the first housing 11, the diapire of the first housing 11 is provided with opening 101, on the diapire that second housing 12 is located at the first housing 11 and by conducting in opening 101 and the first housing 11, outlet 201 is located on the diapire of the second housing 12.
Thus, first housing 11 and the second housing 12 limit closed noise elimination cavity 2, thus coordinate suction tude 3 and steam outlet pipe 4 to eliminate the noise to the waste gas entered in noise elimination cavity 2, liquid gravitate in first housing 11 converges in the second housing 12 automatically, thus is convenient to concentrating and discharge of the liquid in silencing apparatus 100.
Particularly, the second housing 12 is removably located on the diapire of the first housing 11, and thus, when hydrops reaches a certain amount of, user topples over hydrops after directly can pulling down the second housing 12, thus hydrops can be got rid of completely.In addition, containing a large amount of impurity in the waste gas that suction tude 3 is discharged, therefore when on the diapire that the second housing 12 is removably located at the first housing 11, the second housing 12 can be pulled down the impurity in rear cleaning first housing 11 and the second housing 12.
Further, between the first housing 11 and the second housing 12, be provided with Sealing 102, thus ensure the sealing of noise elimination cavity 2, and then ensure the noise elimination effect of silencing apparatus 100.
In specific embodiments more of the present invention, as depicted in figs. 1 and 2, silencing apparatus 100 also comprises dividing plate 5, and dividing plate 5 is provided with the through hole 51 run through on the thickness direction of dividing plate 5, and dividing plate 5 is located at opening 101 place.The inner space of the first housing 11 and the second housing 12 is separated by dividing plate 5, converges at the second housing 12 after the liquid stream via through holes 51 in the first housing 11.Owing to containing a large amount of impurity in the waste gas that suction tude 3 is discharged, therefore the setting of dividing plate 5 can avoid impurity buildups to affect liquid pools and eliminating in the second housing 12.
Particularly, dividing plate 5 is removably located at opening 101 place, and now, user after pulling down the second housing 12, dividing plate 5 successively, can clear up the impurity in the first housing 11.
