In the technical scheme, the first shell is provided with an assembling groove, the second shell is provided with a corresponding assembling protrusion, and the air outlet pipe is arranged on the assembling protrusion. The assembling groove is a concave opening on the first shell, and when the first shell and the second shell are assembled, the assembling protrusion of the second shell can be matched with the assembling groove of the first shell, so that the sealing of the two shells at the air suction port and the air outlet is realized.

It should be noted that the air suction port and the air outlet are respectively arranged on different shells, and the assembly groove and the assembly protrusion can enable the air outlet to be arranged at the central position on the shell of the silencer, so that the air can be discharged from the air outlet more smoothly. In addition, through setting up assembly recess and assembly arch for the position setting of gas outlet has more flexibility, is convenient for the link of muffler and other devices.

Among the above-mentioned technical scheme, the muffler still includes: and the sealing element is arranged on the first shell and/or the second shell so as to realize the sealing connection between the first shell and the second shell.

Among the above-mentioned technical scheme, first cavity and second cavity are the direction of height setting, and the height that highly is less than the second cavity of first cavity, and wherein, the muffler casing is close to one side of second cavity all located to breathing pipe and outlet duct.

In this technical scheme, first cavity and second cavity are direction of height setting, and first cavity and second cavity are with the mode of top and bottom side by side placing promptly, and one side that is close to the second cavity on the muffler casing is all located to breathing pipe and outlet duct. It will be appreciated that if the second chamber is located above the muffler shell, the gas inlet pipe and the gas outlet pipe are both located above the muffler shell, and conversely, the gas inlet pipe and the gas outlet pipe are both located below the muffler shell. Because the suction pipe is connected with the first cavity, the suction pipe extends to a section in the silencer shell and penetrates through the second cavity to be connected with the first cavity. In this way, the suction pipe utilizes partial space of the second cavity, and the space utilization rate of the silencer is improved. Meanwhile, the air suction port of the air suction pipe can be made to face upwards or downwards, and the direction differentiation requirement of the air suction port of the air suction pipe of the compressor is met.

In this technical scheme, when the device is used, fluid flows into the first cavity along with the gas sucked by the gas suction port. Because first cavity and second cavity are the direction of height setting, consequently the fluid that gets into first cavity can be in the bottom gathering of first cavity, influences the work of muffler, probably even along with gaseous follow gas outlet discharge, get into next device in, cause harm to the operation of equipment whole. Through set up the oil leak at first cavity diapire, the fluid of gathering in first cavity bottom will follow the oil leak and flow out first cavity, can not take place the gathering in first cavity. In addition, a baffle plate structure is arranged on the outer wall of the silencer shell and at the position corresponding to the oil leakage port. When fluid drips onto the housing, the fluid will flow down the outer wall of the housing to the bottom of the outer wall of the muffler. There is a possibility that the gas inside the muffler is sucked into the first chamber due to the flow of the gas. Therefore, the baffle structure is arranged at the position corresponding to the oil leakage port, when the fluid flows to the corresponding position of the oil leakage port on the outer wall of the silencer, the fluid can flow along the baffle structure due to the action of the baffle structure and is far away from the oil leakage port, and the fluid is prevented from being sucked into the first cavity from the oil leakage port.

It can be understood that the second baffle is a raised structure disposed above the first baffle, and the fluid flowing to the second baffle is blocked by the second baffle, flows along the edge of the second baffle, and is guided to both sides of the first baffle.

Generally, the second baffle may be an arcuate projection, or a chevron-shaped projection, on the outer wall of the muffler shell. The fluid flows along the second baffle plate and is further guided to the positions, far away from the first baffle plate, of the two sides of the first baffle plate, so that the flow rate of the fluid flowing to the first baffle plate is reduced, and the possibility that the fluid flows into the first cavity from the first baffle plate is further reduced.

Detailed Description

In order to make the above objects, features and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, embodiments of the present invention may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

Some embodiments according to the invention are described below with reference to fig. 1 to 6.

Example one

Meanwhile, because the air suction pipe 108 and the air outlet pipe 110 are arranged on the same side of the silencer shell 102, after the air enters from the air suction pipe 108 and passes through the first cavity 104 and the second cavity 106, the air outlet pipe 110 on the same side returns, so that the first cavity 104 and the second cavity 106 can be arranged in parallel, and because the flowing directions of the air in the first cavity 104 and the second cavity 106 are folded, the two cavities can share the space inside the cavities as the air path for the air to flow, thereby reducing the total occupied volume of the two cavities, further reducing the volume of the silencer 100, and improving the space utilization rate of the silencer 100.

The first cavity 104 and the second cavity 106 are formed by the muffler shell 102, and therefore the first cavity 104 and the second cavity 106 are formed by an internal cavity surrounded by the shell 302, which makes the structure of the muffler 100 simpler and also makes it easier to improve the air tightness of the two cavities of the muffler 100. Meanwhile, the first cavity 104 and the second cavity 106 are formed by directly adopting the shell 302, so that the internal space of the silencer shell 102 can be utilized to the maximum extent to increase the internal space of the two cavities. In addition, the first cavity 104 and the second cavity 106 are communicated with each other, so that gas can flow in from the air suction port, and is discharged from the air outlet after passing through the two cavities, thereby realizing a silencing function.

It should be noted that the gas intake pipe 108 and the gas outlet pipe 110 can be disposed on any side of the muffler shell 102, and the effect of optimizing the structural volume can be achieved. It is apparent that the suction pipe 108 and the discharge pipe 110 are positioned to make the distance of the gas flowing in the chamber as long as possible so as to sufficiently muffle the gas.

Further, for traditional muffler 100, air suction pipe 108 and air outlet pipe 110 are arranged on the same side of muffler shell 102, so that flexibility of design of equipment using the air outlet and the air suction port on the same side is greatly increased, application range of muffler 100 is expanded, and requirement of equipment differentiation is met.

It is apparent that there is only one partition 112 between the first chamber 104 and the second chamber 106, so that the two chambers can make full use of the space in the muffler housing 102. It is apparent that the shape and position of the first and

second chambers

104 and 106 are formed differently depending on the direction and position of the partition 112 disposed in the muffler case 102, so that the positions and inner spaces of the first and second chambers can be changed by changing the position of the partition 112.

The insertion tube 114 is arranged in the silencer shell 102, and the insertion tube 114 can penetrate through the partition plate 112 to communicate the two cavities, so that after the gas enters the first cavity 104, the gas can enter the second cavity 106 through the insertion tube 114, and the insertion tube 114 can guide the flow direction of the gas, so that when the gas can smoothly enter the second cavity from the first cavity, turbulence cannot be generated, and noise is generated.

Meanwhile, because the air suction pipe 108 and the air outlet pipe 110 are arranged on the same side of the silencer shell 102, after the air enters from the air suction pipe 108 and passes through the first cavity 104 and the second cavity 106, the air outlet pipe 110 on the same side returns, so that the first cavity 104 and the second cavity 106 can be arranged in parallel, and because the flowing directions of the air in the first cavity 104 and the second cavity 106 are folded, the two cavities can share the space inside the cavities as the air path for the air to flow, thereby reducing the total occupied volume of the two cavities, further reducing the volume of the silencer 100, and improving the space utilization rate of the silencer 100.

Example four

As shown in fig. 1 to 4, the present embodiment proposes a muffler 100 including: a silencer shell 102, wherein a first cavity 104 and a second cavity 106 which are communicated with each other are formed in the silencer shell 102; an air suction pipe 108 is arranged on the silencer shell 102, and the air suction pipe 108 is communicated with the first cavity 104; the silencer shell 102 is also provided with an air outlet pipe 110, the air outlet pipe 110 is communicated with the second cavity 106, the air inlet pipe 108 and the air outlet pipe 110 are arranged on the same side of the silencer shell 102, so that a structure connected with the air inlet pipe 108 and the air outlet pipe 110 in the equipment can also be arranged on the same side of the silencer 100, the structure in the equipment can be designed to be compact, the utilization rate of the inner space of the equipment is improved, and the structure of the equipment is optimized. Meanwhile, because the air suction pipe 108 and the air outlet pipe 110 are arranged on the same side of the silencer shell 102, after the air enters from the air suction pipe 108 and passes through the first cavity 104 and the second cavity 106, the air outlet pipe 110 on the same side returns, so that the first cavity 104 and the second cavity 106 can be arranged in parallel, and because the flowing directions of the air in the first cavity 104 and the second cavity 106 are folded, the two cavities can share the space inside the cavities as the air path for the air to flow, thereby reducing the total occupied volume of the two cavities, further reducing the volume of the silencer 100, and improving the space utilization rate of the silencer 100.

EXAMPLE five

second chambers

In particular, the seal 124 may provide a protrusion and a groove at the sealed connection of the housing 302 to achieve a slotted connection. The sealing member 124 may also be a sealant, and the two housings 302 may be sealed by adhesion. Sealing rings may also be used to seal the two housings 302.

Further, the muffler 100 further includes: an oil leakage port 126 and a baffle structure 128, wherein the oil leakage port 126 is arranged on the bottom wall of the first cavity 104; the baffle structure 128 is disposed on the outer wall of the muffler shell 102 and corresponds to the oil leakage port 126.

In use of the apparatus, fluid will flow into the first chamber 104 along with the gas drawn through the suction port. Because the first cavity 104 and the second cavity 106 are arranged in the height direction, the fluid entering the first cavity 104 is gathered at the bottom of the first cavity 104, which affects the operation of the silencer 100, and even the fluid may enter the next device along with the gas discharged from the gas outlet, which may cause damage to the overall operation of the equipment. By providing the oil drain 126 at the bottom wall of the first cavity 104, the fluid collected at the bottom of the first cavity 104 will flow out of the first cavity 104 through the oil drain 126, and will not be collected in the first cavity 104. Further, a baffle structure 128 is provided on the outer wall of the muffler case 102 at a position corresponding to the oil drain port 126. When fluid drips onto the housing 302, the fluid will flow down the outer wall of the housing 302 to the bottom of the outer wall of the muffler 100. There is a possibility that the gas flowing inside the muffler 100 is sucked into the first chamber 104. Therefore, the baffle structure 128 is disposed at a position corresponding to the oil leakage port 126, and when the fluid flows to the position corresponding to the oil leakage port 126 on the outer wall of the muffler 100, the fluid flows along the baffle structure 128 and is away from the oil leakage port 126 due to the action of the baffle structure 128, so that the fluid is prevented from being sucked into the first cavity 104 from the oil leakage port 126.

Further, the baffle structure 128 includes: the first baffle 130 is disposed around the oil leakage port 126, and the first baffle 130 separates the fluid flowing near the oil leakage port 126 from the oil leakage port 126. When the fluid flows to the first baffle 130, the first baffle 130 causes the fluid to flow down the first baffle 130. Since the first baffle 130 is disposed around the oil leakage port 126, the fluid flowing down along the first baffle 130 passes through the height of the oil leakage port 126, and flows through the lower end of the first baffle 130 and leaves the first baffle 130 after flowing to a position below the height of the oil leakage port 126. It will be appreciated that the first baffle 130 prevents fluid from flowing to the vicinity of the oil drain 126 and not to the oil drain 126.

The second baffle 132 is disposed above the first baffle 130, and is capable of guiding the fluid to both sides of the first baffle 130. It is understood that the second baffle 132 is a convex structure disposed above the first baffle 130, and after the fluid flows to the second baffle 132, the fluid is stopped by the second baffle 132, flows along the edge of the second baffle 132, and is guided to both sides of the first baffle 130. Generally, the second baffle 132 may be an arcuate projection, or a chevron-shaped projection, on the outer wall of the muffler shell 102. The fluid flows along the second baffle 132 and is directed to the sides of the first baffle 130 away from the first baffle 130, thereby reducing the flow of fluid to the first baffle 130 and further reducing the likelihood that fluid will flow from the first baffle 130 into the first chamber 104.

Further, a partition 112 is provided on the shell a, and the partition 112 divides the space inside the shell a into an upper chamber and a lower chamber. A cannula 114 is provided on the septum 112 for connecting the upper chamber (i.e., the second chamber 106) and the lower chamber.

Further, there are two oil leakage baffles (i.e. baffle structures 128) on the shell a, and one is an arc-shaped baffle (i.e. second baffle 132), which is located at the back of the shell a; one is a cylindrical baffle (i.e., first baffle 130) located on the underside of the curved baffle, at the bottom of shell a.

Further, shell a has a recessed opening (i.e., fitting groove 120) and corresponding shell B has a protruding opening (i.e., fitting protrusion 122), and shell a and shell B are installed in a left-right matching manner, and the recessed opening and the protruding opening are installed in a matching manner to form a closed cavity.

Further, shell B has a recess therein that mates with the baffle 112 on shell a. The partition 112 is fitted into the groove to divide the inner space of the muffler case 102 into upper and lower chambers.

Furthermore, an air outlet pipeline (an air outlet pipe 110) is arranged on the convex opening of the shell B, the inlet of the air outlet pipeline is communicated with the upper cavity in the shell A, and the outlet of the air outlet pipeline faces upwards.

Wherein the inlet line comprises a flare 134 and a straight tube section 136. The shell A is provided with a yielding concave port, and the corresponding shell B is provided with a convex port; the periphery of the shell A is provided with a convex plate, and the periphery of the corresponding shell B is provided with a groove matched with the convex plate; the convex plate and the groove are used as a sealing element 124, so that the shell A and the shell B are installed in a left-right matching mode, the concave opening and the convex opening are installed in a matching mode, and the convex plate and the groove are installed in a matching mode to form a closed cavity.

Shell a has a partition 112 and shell B has a recess that mates with partition 112 on shell a. The partition 112 divides the interior of the muffler shell 102 into two chambers: an upper cavity and a lower cavity. The partition 112 is provided with a cannula 114, the uppermost end of the cannula 114 is inserted into the upper chamber, and the lowermost end of the cannula 114 is inserted into the lower chamber, for connecting the upper chamber and the lower chamber. The straight tube section 136 on the inlet tube is inserted lowermost into the lower cavity.

When fluid flows, the fluid flows from the inlet tube, through the flare 134 and the straight tube section 136 into the lower cavity, and then through the cannula 114 into the upper cavity. And finally out through an outlet pipe.

The back of the shell A is provided with an arc baffle, the bottom of the shell A is provided with a columnar baffle, and the lower end of the shell A is provided with an oil leakage hole (namely an oil leakage hole 126); when lubricating oil flows from top to bottom through the outside back of shell A, the arc baffle disperses the lubricating oil, and the wall surface flows to the outer surface of the columnar baffle, so that the lubricating oil is prevented from being sucked from outside to inside through the oil leakage hole.
