Abstract
The utility model provides a silencer for sewing machines, and comprises a vent pipe (20) and a suction pipe (22), wherein the bottom of the vent pipe is provided with a small aperture channel (202) forming a small angle with the suction pipe. Through providing the vent pipe with the aperture channel with a small inclination, the suction pipe can produce strong suction force when the airflow enters and at the same time the noise is reduced.
Description
Technical field
The utility model relates to a kind of use in sewing machine muffler.
Background technology
Can produce great noise when unnecessary line bits that the collection Sewing machines produces and cloth bits in operating process.For reducing noise, industry usually adopts muffler.
As shown in Figure 1, existing muffler comprises the breather pipe 10 and the suction line 12 of connection, and breather pipe 10 is 45 ° with suction line 12, and breather pipe 10 is used for the air communication mistake, and suction line 12 is used to draw cloth bits etc.Suction line 12 has one and inhales cloth bits mouth 120.When air-flow enters breather pipe 10, produce backflow suction with absorption cloth bits, yet, make that the suction that produces is less, and noise is very big because suction cloth bits mouth 120 is bigger.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiency that above-mentioned prior art exists, and the use in sewing machine that a kind of suction is strong, noise is little muffler is provided.
For solving the problems of the technologies described above, the utility model provides a kind of use in sewing machine muffler, comprises breather pipe and suction line, and the bottom of described breather pipe is provided with a small-bore duct, is a low-angle with described suction line.
Further, the top of described breather pipe is cylindrical, is provided with described suction line is vertical.
Described further low-angle is the unspecified angle between 10 °～30 °.
The utlity model has following useful effect: simple in structure, effectively overcome the defective of existing muffler, by have the small-bore duct of less gradient in the breather pipe setting, make to produce strong suction when air-flow enters air intake duct that noise is but very little simultaneously.
Description of drawings
Fig. 1 is the structural representation of existing muffler.
Fig. 2 is a cross-sectional view of the present utility model.
Fig. 3 is a schematic perspective view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Please be simultaneously with reference to Fig. 2, shown in Figure 3, the utility model use in sewing machine muffler comprises breather pipe 20 and suction line 22, the top 200 of breather pipe 20 is cylindrical, with suction line 22 vertical settings; The bottom of breather pipe 20 is a small-bore duct 202, and itself and suction line 22 are 10 ° of settings.
During use, air-flow enters from breather pipe 20, is blown into air intake duct 22 through duct 202, and will produce strong suction this moment, and reduced many noises.
Be understandable that it is a specific embodiment of the present utility model that small-bore duct 202 is 10 ° with air intake duct 22, from not limiting the utility model.Reach preferable effect, the angle that duct 202 and air intake duct 22 are is between 10 °～30 °.
The utility model makes can produce strong suction when air-flow enters air intake duct that noise is but very little simultaneously by have the small-bore duct of less gradient in the breather pipe setting.
Claims (3)
