Abstract
The utility model relates to an engine accessory, in particular to a power engine muffler, which comprise a shell, a silencing baffle and an adsorption silencing chamber which are arranged in the shell, an air inlet and an air outlet which are arranged on the shell, wherein the bowl-shaped baffle is arranged in the adsorption silencing chamber, and the adsorption silencing chamber is divided into an upper adsorption chamber and a lower adsorption chamber by the adsorption silencing chamber; the upper adsorption chamber is communicated with the lower adsorption chamber, and the lower adsorption chamber is communicated with the air outlet; the upper part of the bowl-shaped baffle is connected onto the silencing baffle, and the bottom of the bowl-shaped baffle is connected with an exhaust bent pipe of the engine; and the exhaust bent pipe of the engine is connected with the bottom of the bowl-shaped baffle through a heat insulation sleeve. With the structure, the power engine muffler has the advantages that: the surface temperature of the muffler shell is reduced, the silencing effect is improved, the service life of the muffler is prolonged, and the service cost is reduced.
Description
Technical field
The utility model relates to motor and uses accessory, specifically is a kind of surface temperature and power engine baffler that reduces user cost of reducing.
Technical background
In the available dynamic technical field of engines, baffler generally is installed is reduced noise, improve engine power and play effect in energy saving and environmental protection.But the baffler of existing technology generally is to adopt dividing plate that enclosure interior is isolated into the absorption silencing cavity, carries out exhaust through suction port and the relief opening that is arranged on the housing, and this structure has reached the effect that reduces noise, improves engine power to a certain extent; But because the outlet pipe of this structure is directly installed on the housing; And the high-temperature tail gas from motor is directly discharged after adsorbing silencing cavity; Make casing surface temperature than higher, be easy to take place the scald accident, Security is low; The working life of baffler is shorter, and replacement cost is just than higher; And high-temp waste gas holdup time in baffler is shorter, and noise reduction is minimum can only to reach 80 decibels, and its erasure effect is poor; Because casing surface temperature is higher, thereby influences connected efficiency of engine and reduce output power, because motor is in the hot environment for a long time, shorten the working life of motor.
In sum, the power engine of existing technology is higher with the muffler shell surface temperature, working life is short and user cost is high.
Summary of the invention
The purpose of the utility model provides a kind of surface temperature and power engine baffler that reduces user cost of reducing.
For realizing that the technological scheme that the utility model purpose adopts is: a kind of power engine baffler comprises housing, is arranged on the silencing board in the housing and adsorbs silencing cavity, is arranged on suction port and relief opening on the housing; Wherein: be provided with a bowl type dividing plate in the said absorption silencing cavity, bowl type dividing plate will adsorb silencing cavity and be isolated into adsorbent chamber and following adsorbent chamber, and last adsorbent chamber communicates with following adsorbent chamber, and following adsorbent chamber communicates with relief opening; The top of bowl type dividing plate is connected on the silencing board, and the bottom of bowl type dividing plate is connected with the engine exhaust bend pipe.Said engine exhaust bend pipe is connected bowl bottom of type dividing plate through collet.
Because said structure, the utility model reduced muffler shell surface temperature, improved erasure effect, prolonged the working life of baffler and reduced user cost.
Description of drawings
The device of the utility model can further specify through the indefiniteness embodiment that accompanying drawing provides.
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure: 1, housing; 2, absorption silencing cavity; 3, bowl type dividing plate; 4, go up adsorbent chamber; 5, following adsorbent chamber; 6, engine exhaust bend pipe; 7, collet; 8, flange plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to accompanying drawing 1, the power engine baffler in the accompanying drawing 1 comprises housing 1, is arranged on the silencing board in the housing 1 and adsorbs silencing cavity 2, is arranged on suction port and relief opening on the housing 1; Wherein: be provided with a bowl type dividing plate 3 in the said absorption silencing cavity 2, bowl type dividing plate 3 will adsorb silencing cavity 2 and be isolated into adsorbent chamber 4 and following adsorbent chamber 5, and last adsorbent chamber 4 communicates with following adsorbent chamber 5, and following adsorbent chamber 5 communicates with relief opening; The top of bowl type dividing plate 3 is connected on the silencing board, and the bottom of bowl type dividing plate 3 is connected with engine exhaust bend pipe 6.In the using process, the tail gas that motor is discharged no longer is directly to discharge through the relief opening that adsorbs silencing cavity 2 and communicate with absorption silencing cavity 2, but earlier through last adsorbent chamber 4; Through following adsorbent chamber 5, after the relief opening discharge, compared with prior art; The holdup time of waste gas in baffler prolongs, and the low energy of noise reduction reaches 70 decibels, makes when having improved sound-absorbing effect; Can also reduce the temperature of waste gas, also just make the temperature on baffler surface reduce, improve the power of motor; Can also prolong the working life of baffler, reach the purpose that reduces user cost.
For further reducing the muffler shell surface temperature, improve engine power, the bend pipe 6 of engine exhaust described in the foregoing description is connected bowl bottom of type dividing plate 3 through collet 7.Because setting up of collet 7, the temperature of engine exhaust bend pipe 6 has no longer been transmitted on the muffler shell 1, effectively reduces the surface temperature of muffler shell 1.
For ease of connecing with engine exhaust port, the inlet end of the said engine exhaust bend pipe 6 of said structure is provided with flange plate 8.
In sum, this structure reduced muffler shell surface temperature, improved erasure effect, prolonged the working life of baffler and reduced user cost.
