Description

Muffler for motor and smoke ejector connection structure
Technical field
The utility model is about a kind of engine smoke discharging device structure, especially with regard to a kind of muffler for motor and smoke evacuation Device connection structure.
Background technique
Many engine smoke discharging devices are all very long, and occupied space is big, and weight is also very big, fixes and supports this smoke ejector just Become the problem of engine producer and vehicle factor.Smoke ejector is connect with silencer by exhaust connection, in order to solve because The problem of smoke ejector and silencer are broken caused by engine luggine, by the way that wave is arranged between smoke ejector and exhaust connection Line pipe carrys out transition.However, structure is complicated for bellows, manufacture is difficult, considerably increases the production cost of engine.Even if using Bellows, which carrys out transition, can not fully eliminate the power that part directly contacts generation, under the vibration of vehicle and engine, eliminate the noise All there is the risk of fracture in device and exhaust connection and smoke discharging.
The information disclosed in the background technology section is intended only to increase the understanding to the general background of the utility model, and It is not construed as recognizing or implying in any form that information composition is already known to those of ordinary skill in the art existing Technology.
Utility model content
The purpose of this utility model is to provide a kind of muffler for motors and smoke ejector connection structure, can effectively solve The problem of silencer, exhaust connection and smoke ejector caused by stress are broken caused by certainly being vibrated due to engine and vehicle.
To achieve the above object, the utility model provides a kind of muffler for motor and smoke ejector connection structure, comprising: Silencer;Smoke ejector, is provided with smoke ejector interface, and smoke ejector interface is hollow bell-mouth structure of air;And exhaust connection, The leading portion of exhaust connection is connect with silencer, and the tailpipe section of exhaust connection is inserted into smoke ejector interface, and tailpipe section with Smoke ejector interface does not contact.
In a preferred embodiment, bell-mouth structure of air includes tubaeform upper section and cylindrical body lower section.
In a preferred embodiment, the end of tailpipe section extend into tubaeform upper intersegmental part, and with tubaeform upper section Inner wall do not contact.
In a preferred embodiment, it is welded with snap ring on smoke ejector, smoke ejector is fixed on vehicle by snap ring.
In a preferred embodiment, the leading portion of exhaust connection is fixedly connected by flange with silencer.
In a preferred embodiment, the quantity of snap ring is two.
Compared with prior art, muffler for motor and smoke ejector connection structure according to the present utility model: by that will arrange Cigarette device interface is set as the hollow bell-mouth structure of air of non-contact type, can effectively solve the problem that caused by being vibrated due to engine and vehicle The problem of silencer caused by stress, exhaust connection and smoke ejector are broken.And the smoke ejector structure of the utility model is simple, Light-weight, easily manufactured, low cost can fix simply on vehicle, and contactless with engine, dismounting is simple, convenient and efficient. Due to not having bellows, heat-insulated package is simply, conveniently, at low cost.
Detailed description of the invention
Fig. 1 is shown according to the muffler for motor and smoke ejector connection structure stereochemical structure of one embodiment of the utility model It is intended to.
Fig. 2 is the main view of the muffler for motor and smoke ejector connection structure according to one embodiment of the utility model.
Fig. 3 is schematic diagram of the Fig. 2 along the direction A-A.
Main appended drawing reference explanation:
1- silencer, 2- smoke ejector, 21- smoke ejector interface, 22- snap ring, 211- is tubaeform upper section, under 212- cylindrical body Section, 3- exhaust connection, 31- tailpipe section.
Specific embodiment
With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail, it is to be understood that this is practical Novel protection scope is not limited by the specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " includes " or its change Changing such as "comprising" or " including " etc. will be understood to comprise stated element or component, and not exclude other members Part or other component parts.
As shown in Figure 1 to Figure 3, knot is connected with smoke ejector according to the muffler for motor of the preferred embodiments of the present invention Structure, comprising: silencer 1, smoke ejector 2 and exhaust connection 3.Wherein, smoke ejector 2 is provided with smoke ejector interface 21, smoke ejector Interface 21 is hollow bell-mouth structure of air.3 leading portion of exhaust connection is connect with silencer 1, the tailpipe section 31 of exhaust connection 3 It is inserted into smoke ejector interface 21, and tailpipe section 31 is not contacted with smoke ejector interface 21.
In above scheme, bell-mouth structure of air includes tubaeform upper section 211 and cylindrical body lower section 212.The end of tailpipe section 31 It is extend into tubaeform 211 inside certain depth of upper section, and is not contacted with the inner wall of tubaeform upper section 211.Preferably, tailpipe section 31 End extend into the depth inside tubaeform upper section 211 be less than or equal to tubaeform 211 length of upper section half.
It is welded with snap ring 22 on smoke ejector, smoke ejector 1 is fixed on vehicle by snap ring 22.Preferably, the number of snap ring Amount is two.
