Embodiment Construction

[0006] The present invention is an improvement to the existing cylindrical muffler. It includes a drainage tube with a connecting flange 8 and a muffler base 7. The air flow channel 4 is reserved on the circumference and outer end of the drainage tube and fixed with a connecting piece 3. There is a sleeve 5, and the connecting piece can be slat-shaped or cylindrical and fixed with screws or glue. The center of the outer end of the sleeve leaves a sound transmission channel to the periphery of the cavity of the drainage tube, and a sound-absorbing cone 6 is fixed. In order to make the length shorter, another layer of outer sleeve 2 can be installed on the outer circle of the sleeve. The head end of the outer sleeve is sleeved on the drainage tube near the flange. The inner wall of the outer sleeve and the sleeve Connecting pieces are fixed between the outer walls of the silencing channel to communicate outwardly. When working, the airflow flows back and forth in the curved airf...

Abstract

The invention discloses a sleeve muffler, which comprises a drainage tube with a flange and a muffler base. The periphery and the outer end of the drainage tube are respectively provided with a channel so as to fix a sleeve with an edge connector, and a channel is reserved from the center of a seal head of the outer end of the sleeve to the periphery of the drainage tube so as to fix a muffler cone. The invention has a compact structure, and the length of the invention is only one third of the cylindrical muffler. Moreover, the invention ensures the muffling effect and has a wide scope of installation and application.

Description

Technical field: [0001] The invention relates to a muffler, in particular to a sleeve type muffler suitable for installing on the inlet and outlet of a fan to eliminate noise and protect the environment. Background technique: [0002] Currently, there are many kinds of mufflers on the market, such as box-type mufflers, chip mufflers and cylindrical mufflers. Although they all have a certain muffling effect, the disadvantages of large storage are that they are large in size, large in length, and occupy a large space. They cannot be installed in a small space. Summary of the invention: [0003] The purpose of the present invention is to provide a sleeve type muffler with compact structure, small occupation space and wide application range. [0004] The technical scheme of the present invention is completed in the following manner, which includes a flanged drainage tube and a muffler base, characterized in that: the drainage tube is fixed on the circumference and outer end of the chan...
