Abstract
The utility model discloses a noise-reduction smoke discharging pipe which comprises a hollow smoke discharging cavity. A pair of inlet connecting pipes is arranged at the head of the smoke discharging cavity. A pair of outlet connecting pipes are arranged at the tail of the smoke discharging cavity. An 'X'-shaped silencing connecting pipe is arranged between the inlet connecting pipes and the outlet connecting pipes. Sound absorbing foam is disposed in the smoke discharging cavity. By the double inlets, the double outlets and the 'X'-shaped silencing connecting pipe, distribution and remixing of air flows is achieved, and accordingly air flow pulsation phase in two passages is offset, and vibration and noise of smoke discharging are lowered greatly. In addition, by the sound absorbing foam disposed in the smoke discharging cavity, vibration and noise are further lowered.
Description
Technical field
The utility model relates to a kind of fume extractor, or rather, is a kind of noise reduction formula smoke-ejecting pipe.
Background technique
Smoke-ejecting pipe is a kind of device that is specifically designed to discharging waste gas or useless cigarette, is used for all trades and professions.Existing smoke-ejecting pipe adopts single tube directly to discharge fume more, and vibrations and noise that pulse pneumatic brings are very big, and the life-span is also very short.
Summary of the invention
The utility model mainly is to solve the existing in prior technology technical problem, thereby a kind of noise reduction formula smoke-ejecting pipe is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of noise reduction formula smoke-ejecting pipe, described noise reduction formula smoke-ejecting pipe comprises the smoke extraction chamber of a hollow, the head of described smoke extraction chamber is provided with a pair of inlet connection, and the afterbody of smoke extraction chamber is provided with a pair of discharge connection, and the noise reduction that is provided with one " X " shape between described inlet connection and the discharge connection is taken over.
As the utility model preferred embodiment, be provided with sound-absorbing foam in the described smoke extraction chamber.
The two entrances of noise reduction formula smoke-ejecting pipe utilization of the present utility model and two outlets, the noise reduction of utilization " X " shape are simultaneously taken over air-flow are shunted and mixing again, thereby offset the pulsation phase of the air-flow in two passages, greatly reduce vibrations and the noise of smoke evacuation.In addition, owing to be provided with sound-absorbing foam in the smoke extraction chamber, vibrations and noise have further been reduced.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the perspective view of noise reduction formula smoke-ejecting pipe of the present utility model;
Fig. 2 is the perspective view of the noise reduction formula smoke-ejecting pipe among Fig. 1, and be another visual angle this moment;
Fig. 3 is that noise reduction formula smoke-ejecting pipe among Fig. 2 is along the sectional view of A-A line;
Wherein,
1, noise reduction formula smoke-ejecting pipe; 2, smoke extraction chamber; 21, sound-absorbing foam; 3, inlet connection; 4, discharge connection; 5, noise reduction is taken over.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As shown in Figure 1 to Figure 3, noise reduction formula smoke-ejecting pipe 1 of the present utility model comprises the smoke extraction chamber 2 of a hollow, the head of this smoke extraction chamber 2 is provided with a pair of inlet connection 3, and the afterbody of smoke extraction chamber 2 is provided with a pair of discharge connection 4, and the noise reduction that is provided with one " X " shape between inlet connection 3 and the discharge connection 4 takes over 5.
Be provided with sound-absorbing foam 21 in this smoke extraction chamber 2.
The above only is embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
