Abstract
Description
Technical Field
[0001] This utility model relates to a muffler, and more particularly, to an easy-to-clean muffler. Background Technology
[0002] A muffler is a device used to reduce noise and is widely used in various fields. Its principle is to reduce the sound energy and achieve the purpose of noise reduction by making sound waves reflect and interfere during propagation through internal structural design. Mufflers used in automobiles often generate dust and impurities during exhaust, and these dust and impurities can easily remain inside the muffler, affecting its performance. However, mufflers are generally made of one piece, which requires cleaning the entire muffler during cleaning. Furthermore, when the muffler is blocked, it needs to be cut open for treatment, which is very troublesome. Utility Model Content
[0003] Therefore, it is necessary to provide an easy-to-clean muffler.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an easy-to-clean muffler includes a cylinder, an end cap, an air inlet pipe, a partition, bolts, a baffle plate, sound insulation cotton, an exhaust pipe, and a buffer chamber. The end cap is detachably installed on the cylinder. One end of the cylinder is provided with an air inlet pipe, and the other end is provided with an exhaust pipe. The air inlet pipe is provided through the end cap. A partition is provided inside the cylinder. The cylinder is divided into two buffer chambers by the partition. The baffle plate is fixedly installed on the outside of the cylinder by bolts. Sound insulation cotton is placed inside the baffle plate. The partition plate and the sound insulation cotton are connected to divide the inside of the cylinder to form a buffer chamber.
[0005] Furthermore, the partitions are spaced in three intervals.
[0006] Furthermore, the barrier plates are spaced three apart, and each barrier plate is fixed to the cylinder by two bolts.
[0007] Furthermore, the air intake pipe is installed through the end cap, and a filter cotton is fixedly installed at the inner port of the air intake pipe.
[0008] Furthermore, a sound-absorbing layer is fixedly applied to the surface of the partition.
[0009] Furthermore, the cylinder body and the end cap are connected by bolts, snaps, or latches.
[0010] The beneficial effects of this utility model are as follows: This utility model provides an easy-to-clean muffler. By setting a baffle, the muffler cylinder is divided into different buffer chambers, and the baffle is arc-shaped, so that the sound waves are attenuated and weakened multiple times. At the same time, with the help of sound insulation cotton and filter cotton, the noise is further reduced. In addition, since the end cap and baffle are detachable, it is convenient for operators to clean and replace the filter cotton in the air intake pipe and the sound insulation cotton in the baffle. Attached Figure Description
[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0012] Figure 1 This is a structural schematic diagram of an easy-to-clean muffler according to the present invention.
[0013] The component names and their numbers in the diagram are as follows:
[0014] 1. Cylinder body; 2. End cap; 3. Air inlet pipe; 4. Filter cotton; 5. Partition plate; 6. Bolt; 7. Barrier plate; 71. Fixing hole; 8. Sound insulation cotton; 9. Exhaust pipe; 10. Buffer chamber. Detailed Implementation
[0015] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0016] like Figure 1 As shown, the present invention provides an easy-to-clean muffler, comprising a cylinder 1, an end cap 2, an air inlet pipe 3, a filter cotton 4, a partition 5, bolts 6, a barrier plate 7, sound insulation cotton 8, an exhaust pipe 9, and a buffer chamber 10. One end of the cylinder 1 is provided with an opening, and the end cap 2 is detachably installed at the opening of the cylinder 1. The detachable connection structure between the end cap 2 and the cylinder 1 can be achieved by using bolt connection, snap-fit connection, or fastener connection as in the prior art.
[0017] The air inlet pipe 3 is fixedly installed on the end cover 2. A filter cotton 4 is fixedly installed at the inner interface of the air inlet pipe 3. When the gas enters the cylinder 1, the dust and impurities in the gas will be intercepted by the filter cotton 4 inside the air inlet pipe 3, so as to reduce the amount of debris entering the cylinder 1 and ensure that the noise reduction function of the silencer is not affected.
[0018] The partition 5 is fixedly installed on the inner wall of the cylinder 1. There are three partitions 5 in total. Each pair of adjacent buffer chambers is separated by the partition 5. The partition 5 is arc-shaped. A baffle 7 is fixedly installed on the outside of the cylinder 1 and extends into the inside of the cylinder 1. The baffle 7 extends into the inside of the cylinder 1 to form a groove. Sound insulation cotton 8 is installed in the groove. Part of the sound insulation cotton 8 is located in the groove. Part of the sound insulation cotton 8 extends into the inner cavity of the cylinder 1 and abuts against the partition 5. Together with the partition 5, the inside of the cylinder 1 is divided into two adjacent buffer chambers 10.
[0019] The baffle plate 7 extends along the outer side of the cylinder 1 to form an extension. The extension is provided with a fixing hole 71. The bolt 6 is connected to the fixing hole 71 and fixedly installed on the cylinder 1. The surface of the baffle plate 5 is covered with a sound-absorbing layer. The sound-absorbing material used in the sound-absorbing layer is ultra-fine glass fiber cotton, which has a good sound absorption and noise reduction effect.
[0020] When gas enters the buffer chamber 10 inside the cylinder 1 from the air inlet pipe 3, it enters the next buffer chamber 10 through the sound insulation cotton 8. Because the partition 5 is arc-shaped, the sound waves are fully reflected and interfered with after contacting the partition 5, and then enter the next chamber through the sound insulation cotton 8.
[0021] After the muffler has been used for a period of time, dust accumulates inside the cylinder 1 to a certain extent. In order to avoid affecting the exhaust and muffler effect, the cylinder 1 needs to be disassembled for cleaning. Remove the end cap 2 from the cylinder 1, clean the air intake pipe 3 on the end cap 2, and replace the filter cotton 4 on the air intake pipe 3. Then install it on the cylinder 1. Remove the bolts 6 on the baffle plate 7, clean or replace the sound insulation cotton 8 in the groove of the baffle plate 7. Repeat the operation three times. Finally, install it on the cylinder 1. After installation, the muffler continues to work.
[0022] This utility model discloses an easy-to-clean muffler. By setting a partition 5, the inside of the muffler cylinder 1 is divided into different buffer chambers 10. The partition is arc-shaped, which causes the sound waves to be attenuated and weakened multiple times. At the same time, with the help of sound insulation cotton 8 and filter cotton 4, the noise is further reduced. In addition, since the end cap 2 and the baffle plate 7 are detachable, it is convenient for operators to clean and replace the filter cotton 4 in the air inlet pipe 3 and the sound insulation cotton 8 in the baffle plate 7.
[0023] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
