Abstract
The utility model discloses an engine exhaust pipe muffler, in particular to an engine exhaust pipe muffler mounted vertically, belonging to the vehicle fitting technical field, which comprises a muffler case and a muffler intake pipe, wherein the lower part of the muffler case is provided with a chamber separated by a horizontal water eliminator, the bottom of the chamber is arranged with a drain valve, the periphery of the water eliminator is provided with through holes, the orifice of the muffler intake pipe is higher than the inner surface of the muffler case and lower than the lower surface of the water eliminator. The engine exhaust pipe muffler can avoid water entering into engines.
Description
(1) technical field
The utility model relates to a kind of engine exhaust muffler pipe, and especially vertically the engine exhaust muffler pipe of installing belongs to the car accessories technical field.
(2) background technique
The engine exhaust muffler pipe is installed on the waste pipe, is mainly used in the operational noise that reduces motor, and specific targets are to make its noise less than 85dB.But for the upwards vertical baffler of installing of some relief openings, on rainy day, rainwater is easy to enter motor by baffler, has had a strong impact on the working life of motor.Although at present for the baffler of installing straight up, its relief opening is made forward or structure backward usually, be provided with the rain-baffling device of turriform above perhaps.For relief opening mounting type forward, motor can make its exhaust pressure increase because of the blast in the vehicle driving process, and energy consumption increases, and the effect and bad of keeping off the rain; For relief opening mounting type backward, because the flow-disturbing effect of outlet pipe self, the gas that circles round still carries a spot of water and enters outlet pipe; And, can have same problem for the rain-baffling device that is provided with turriform, the air-flow in the vehicle traveling process can carry some moisture and enter outlet pipe.The structure of simple change relief opening can not avoid water to enter motor fully.
(3) summary of the invention
The occasion that the utility model vertically fixes a silencer at present motor car engine can't be avoided having the defective that moisture enters motor on rainy day, and a kind of engine exhaust muffler pipe of avoiding moisture to enter motor is provided.
The technical solution adopted in the utility model is:
The utility model engine exhaust muffler pipe, comprise suppressor case and baffler suction tude, described muffler shell bottom is provided with the cavity that is divided into by horizontally disposed manger board, and this cavity bottom is provided with drain valve, and wherein the manger board periphery is provided with through hole; The described baffler suction tude mouth of pipe is higher than described suppressor case internal surface, and is lower than the manger board lower surface.
Above-mentioned engine exhaust muffler pipe, described cavity are that the bottom is that segment shape, taper, frustoconic shape or cross section are the structure of wedge shape.
The utility model engine exhaust muffler pipe is the improvement design on the basis that enters engine structure in existing waterproof, and what mainly consider is the handling problem that has after some water enter, thereby thoroughly solves in the problem of overcast and rainy motor from the relief opening water inlet.
The lower housing portion of the utility model engine exhaust muffler pipe is provided with the cavity that is divided into by horizontally disposed manger board, and this cavity is used for the water that enrichment is come in by muffler tail pipe.Wherein the manger board periphery is provided with through hole, is used for exhaust, and after current get off, can be along this through hole to dirty, and can not flow directly in the silencing apparatus suction tude.This baffler suction tude mouth of pipe is higher than described suppressor case internal surface, and is lower than the manger board lower surface, and this of described cavity section zone is the water of the multipotency enrichment of this cavity.And this cavity bottom is provided with drain valve, after the parking, opens this drain valve, and the water that bleeds off the inside gets final product.On the basis of original waterproofing design, the water of coming in can be not a lot, even if so mileage is long, described cavity also can hold these water, thereby thoroughly solve motor in overcast and rainy problem from the relief opening water inlet.
(4) description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, suppressor case, 2, through hole, 3, manger board, 4, the silencing apparatus suction tude, 5, cavity, 6, drain valve.。
(5) embodiment
Specify structural principle of the present utility model below in conjunction with Figure of description:
With reference to explanation accompanying drawing 1, present embodiment engine exhaust muffler pipe, comprise suppressor case 1 and baffler suction tude 4, described muffler shell 1 bottom is provided with the cavity 5 that is divided into by horizontally disposed manger board 4, this cavity bottom is provided with drain valve 6, and wherein the manger board periphery is provided with through hole 2; Described baffler suction tude (4) mouth of pipe is higher than described suppressor case internal surface, and is lower than the manger board lower surface.
In order to obtain the effect of reasonable enrichment water, to be convenient to water and to flow out, described cavity 5 is that segment shape, taper, frustoconic shape or cross section are the structure of wedge shape for the bottom, these four kinds of structures all are beneficial to enrichment water, and also are beneficial to the outflow of water.
Claims (2)
1. engine exhaust muffler pipe, comprise suppressor case (1) and baffler suction tude (4), it is characterized in that: described muffler shell (1) bottom is provided with the cavity (5) that is divided into by horizontally disposed manger board (4), this cavity bottom is provided with drain valve (6), and wherein the manger board periphery is provided with through hole (2); Described baffler suction tude (4) mouth of pipe is higher than described suppressor case internal surface, and is lower than the manger board lower surface.
2. engine exhaust muffler pipe according to claim 1 is characterized in that; Described cavity (5) is that segment shape, taper, frustoconic shape or cross section are the structure of wedge shape for the bottom.
