[0045] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings.

[0046] Please also see Figure 1 and Figure 2 The embodiment of the present invention provides a silencer device 100 , which includes a housing 10 , a flow divider 20 , and a plurality of silencers 30 .

[0047] The housing 10 has a housing chamber 11 therein. The housing 10 is provided with an air inlet 12 and a first air outlet 13, each of which is connected to the housing chamber 11. The air inlet 12 and the first air outlet 13 are spaced apart. A flow divider 20 is disposed within the housing chamber 11. A curved channel 21 is defined within the flow divider 20, with the ends of the curved channel 21 connecting the air inlet 12 and the first air outlet 13, respectively. Multiple silencers 30 are spaced apart within the curved channel 21 and are all connected to the flow divider 20. The silencers 30 are used to reduce the noise of the airflow passing through the curved channel 21. Specifically, the silencers 30 are polyurethane honeycomb foam.

[0048] The above-mentioned silencer 100 is configured by providing a curved channel 21 on the flow divider 20 in the housing 10, and arranging a plurality of silencers 30 at intervals in the curved channel 21. When gas enters the curved channel 21 from the air inlet 12, the plurality of silencers 30 can cooperate to eliminate the noise of the gas passing through the curved channel 21. Since the length of the curved channel 21 is relatively long and the number of silencers 30 is set to be multiple, the silencer effect is better.

[0049] The housing 10 includes a carrier 14 and a cover 15. The carrier 14 is plate-shaped, and the accommodating cavity 11, the air inlet 12, and the first air outlet 13 are all formed on the carrier 14. The cover 15 is plate-shaped and is mounted on the carrier 14 to cover the accommodating cavity 11. The arrangement of the carrier 14 and the cover 15 facilitates the creation of the accommodating cavity 11 for placing the flow divider 20.

[0050] In this embodiment, the flow divider 20 and the carrier 14 are an integral structure. It is understood that in other embodiments, the flow divider 20 and the carrier 14 are separate structures.

[0051] The housing 10 further includes a sealing member 16, which is disposed between the carrier 14 and the cover 15 to seal the gap between the carrier 14 and the cover 15, thereby achieving a seal between the carrier 14 and the cover 15. Specifically, the sealing member 16 is a sealing strip.

[0052] The housing 10 further includes a fixing member 17 , which is generally sheet-shaped and disposed on one side of the carrier 14 . The fixing member 17 is provided with fixing holes 172 . Specifically, there are three fixing holes 172 for fixing the carrier 14 .

[0053] In this embodiment, the fixing member 17 and the supporting member 14 are an integral structure. It is understood that in other embodiments, the fixing member 17 and the supporting member 14 are separate structures.

[0054] The silencer 100 further includes a connector 40, which is disposed on the carrier 14 and communicates with the air inlet 12. By providing the connector 40, the air inlet 12 can be communicated with an external electromagnetic valve.

[0055] The flow divider 20 is provided with a plurality of groups of receiving holes 22 spaced apart along a first direction. In this embodiment, the first direction is the X-axis. Each group of receiving holes 22 is provided with a plurality of receiving holes 22 spaced apart along a second direction perpendicular to the first direction. In this embodiment, the second direction is the Y-axis. Each receiving hole 22 is connected to the curved channel 21. The plurality of silencers 30 are respectively disposed in the plurality of receiving holes 22. The provision of the plurality of receiving holes 22 facilitates the separate securing of the plurality of silencers 30.

[0056] Each accommodating hole 22 includes a connecting hole section 221 and two side hole sections 222. The connecting hole section 221 communicates with the curved channel 21. The two side hole sections 222 are symmetrically arranged relative to and connected to the connecting hole section 221. The distance between the two side hole sections 222 gradually increases along the flow direction of air in the curved channel 21. The silencer 30 is disposed within the connecting hole section 221 and the two side hole sections 222. Since the distance between the two side hole sections 222 gradually increases along the flow direction of air in the curved channel 21, the airflow noise can be dispersed and reduced, thereby changing the circulation direction of the divergent airflow ejected from the cylinder, etc.

[0057] The air inlet 12 and the first air outlet 13 are spaced apart and arranged on the same side of the housing 10. In this way, the airflow silencing length can be increased and the silencing effect is better.

[0058] The housing 10 also includes multiple second air outlets 18. These are located on adjacent sides of the housing 10 and communicate with the air inlet 12, respectively, and are all connected to the curved passage 21. The first air outlet 13 is located between the air inlet 12 and the multiple second air outlets 18. Specifically, there are multiple first air outlets 13, and both the multiple first air outlets 13 and the multiple second air outlets 18 are arranged in a mesh pattern. The provision of multiple second air outlets 18, with the second air outlets 18 located adjacent to the air inlet 12 on the housing 10, facilitates the rapid discharge of any unabated strong airflow, preventing cylinder degassing, which could affect the cylinder's movement speed.

[0059] The curved channel 21 includes a first channel 211, a second channel 212, and a third channel 213. One end of the first channel 211 communicates with the air inlet 12. The second channel 212 is located on one side of the first channel 211, and one end of the second channel 212 communicates with the end of the first channel 211 away from the air inlet 12. One end of the third channel 213 communicates with the other end of the second channel 212, and the other end of the third channel 213 communicates with the first air outlet 13. Specifically, there can be one or more second channels 212. When there are multiple second channels 212, the multiple second channels 212 are distributed in an S-shape. By providing the first channel 211, the second channel 212, and the third channel 213, the airflow muffling length can be increased, thereby improving the muffling effect.

[0060] The implementation process of the muffler device 100 of the embodiment of the present application is as follows:

[0061] Please also see Figure 3 The gas discharged from the cylinder 300 enters the curved channel 21 on the flow divider 20 in the housing 10 from the joint 40 through the solenoid valve 200. When the air flow flows in the curved channel 21, it is silenced by multiple silencers 30 and discharged from multiple first air outlets 13 and multiple second air outlets 18.

[0062] The silencer device 100 of the present embodiment utilizes an S-shaped curved channel 21 within the flow divider 20 to increase the airflow's muffled length. The layered reverse slope design disperses and reduces airflow noise, thereby redirecting the airflow generated by the cylinder 300 and other components. Furthermore, the installation of a silencer 30 within the curved channel 21 gradually transforms and attenuates the sound transmitted through the air, thereby reducing the airflow noise generated by the cylinder 300 and other components when exhausting.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be encompassed within the present invention.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
