Description

Technical Field

[0001] The utility model relates to the technical field of mufflers, in particular to a muffler component that is easy to disassemble and assemble. Background Art

[0002] A muffler is a device that blocks sound propagation but allows airflow to pass through. It is an important measure to eliminate aerodynamic noise. A muffler is a noise-reducing device installed on the airflow channel or in the intake and exhaust system of an aerodynamic device (such as a blower, an air compressor, a boiler exhaust port, a generator, a water pump, and other equipment with relatively loud exhaust noise). In the prior art, a muffler is generally connected by welding. For example, a patent document with a publication number of CN 219318619 U discloses a stainless steel muffler assembly and an exhaust pipe assembly, comprising a stainless steel muffler, a stainless steel pipe, a first copper sleeve, and a second copper sleeve. The first copper sleeve is fixedly connected to one end of the stainless steel muffler, the other end of the stainless steel muffler is fixedly connected to one end of the stainless steel pipe, and the other end of the stainless steel pipe is fixedly connected to the second copper sleeve. The exhaust pipe assembly includes the above-mentioned stainless steel muffler assembly, a first copper pipe and a second copper pipe, one end of the first copper pipe is fixedly connected to the first copper sleeve in the stainless steel muffler assembly, and the other end is used to connect to the stop valve, one end of the second copper pipe is fixedly connected to the second copper sleeve in the stainless steel muffler assembly, and the other end is used to connect to the four-way valve. The advantages of the utility model are: not only can the overall production cost of the air-conditioning system be reduced accordingly, but also the product welding quality can be improved and the welding consistency can be ensured. However, the assembly makes it inconvenient to disassemble and assemble the muffler and other components, and the welding connection causes the entire assembly to be replaced when a component is damaged, which wastes materials and increases costs. Utility Model Content

[0003] The utility model provides a muffler assembly that is easy to disassemble and assemble, thereby solving the problems in the prior art that the muffler is inconvenient to disassemble and assemble and cannot be reused.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A muffler assembly that is easy to disassemble and assemble, comprising:

[0006] A silencer, the silencer comprising a first silencer and a second silencer;

[0007] A connecting pipe, the connecting pipe connecting the first muffler and the second muffler;

[0008] Copper head, the copper head is installed on the muffler;

[0009] The invention is characterized in that: both ends of the connecting pipe are provided with clamping parts, and the muffler is provided with matching parts, and the clamping parts cooperate with the matching parts to realize the connection between the connecting pipe and the muffler. This connection method is not only simple and convenient, but also can effectively ensure the firmness and sealing of the connection.

[0010] Furthermore, a seal is installed on the clamping portion, and installing the seal can ensure that the sound waves inside the muffler will not be disturbed by leakage, thereby improving the overall muffler effect.

[0011] Furthermore, the muffler includes a threaded section, the connecting pipe is provided with a mating section, the mating section is provided with a thread with the same parameters as the threaded section, the mating section is threadedly connected with a fixing piece, the connecting pipe and the muffler are connected by the fixing piece, and a very strong connection can be achieved between the connecting pipe and the muffler through the threaded connection, which not only ensures a close combination between the two, but also can resist external vibration and impact, and ensure the stability of the entire muffler structure. The threaded connection has the characteristics of convenient disassembly and installation, making the maintenance and replacement of the muffler easier.

[0012] Furthermore, positioning grooves are provided at both ends of the connecting pipe, and corresponding positioning parts are provided at the mating ends of the muffler and the connecting pipe. The positioning parts are snapped into the positioning grooves. The cooperation between the positioning grooves and the positioning parts makes the installation process simpler and ensures the accuracy of the position during connection. This avoids the problem of loose connection or difficult installation due to position deviation, and improves the efficiency and accuracy of installation.

[0013] Furthermore, the connecting pipe includes a bent pipe and a connecting pipe, and the bent pipe and the connecting pipe are snap-fitted together, which makes the installation process simple and quick. The snap-fit ​​does not require complicated tools or equipment. It only requires aligning the bent pipe and the connecting pipe and gently tightening them, which greatly saves installation time and labor costs.

[0014] Furthermore, the connection end of the elbow and the connecting pipe is provided with a mounting part, and the connecting pipe is provided with a guiding part. The mounting part and the guiding part cooperate to realize the connection between the elbow and the connecting pipe, which not only improves the accuracy and stability of the connection, but also simplifies the installation process. The operator only needs to align the mounting part of the elbow with the guiding part of the connecting pipe, and then cooperate in a predetermined manner. The cooperation between the mounting part and the guiding part can also provide a certain sealing performance and reduce the risk of fluid leakage at the connection. This is crucial to ensure the normal operation and performance of the muffler.

[0015] Furthermore, a locking assembly is provided on the connecting pipe, and the locking assembly includes a button, a locking piece, an elastic piece, a pin shaft, a thrust piece and a fixed seat.

The elastic piece is sleeved on the pin shaft and limited in the fixed seat, and the locking piece is sleeved in the button and connected to the fixed seat. A locking groove is provided on the bent pipe, and the button drives the pin shaft to engage or disengage with the locking groove. When the button is pressed, the thrust piece will push the pin shaft to move in the direction of the locking groove, and the elastic piece will be compressed until the pin shaft is completely engaged in the locking groove. At this time, the locking piece and the thrust piece cooperate to lock the pin shaft to realize the connection between the bent pipe and the connecting pipe. When the bent pipe and the connecting pipe need to be separated, just press the button again, and the pin shaft will disengage from the locking groove under the push of the elastic piece, thereby realizing convenient separation.

[0016] Furthermore, the coaxiality between the connecting pipe and the first muffler is a, Φ0.1mm<a<Φ0.3mm. By setting a reasonable coaxiality, the matching accuracy between the connecting pipe and the first muffler is ensured to prevent problems such as assembly difficulties, increased vibration and noise, and performance degradation caused by imprecise matching.

[0017] Furthermore, silencer holes are staggered on the connecting pipe. The staggered silencer holes mean that these holes are not evenly distributed on the connecting pipe, but are arranged in a certain staggered pattern. This design can more effectively disperse the impact force and vibration of the fluid flow, thereby further absorbing and reducing noise.

[0018] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0019] The utility model discloses a muffler component which is easy to disassemble and assemble. Both ends of a connecting pipe are provided with clamping parts, and a matching part is provided in the muffler.
