Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, but does not constitute any limitation to the present invention. figure 1 and figure 2 As shown, the present invention includes a casing 1, the bottom of the casing 1 is distributed with exhaust holes, and the center of the bottom is provided with a filter element hole for installing the filter element. A filter element is housed in the filter element hole, and the filter element can be directly loaded from the bottom of the shell 1 so that the shell 1 is buckled on the filter element, and the top of the filter element and the top of the shell 1 can also be fixed as one. The filter element is integrated by the inner core 3 and the outer core 2. The side walls of the inner core 3 and the outer core 2 are provided with air holes. For better noise reduction, the inner core 3 is made of wood, and the outer core 2 is made of metal. The absorbed no...

Abstract

The invention discloses an air pump muffler which can be used for effectively reducing noise. The air pump muffler disclosed by the invention comprises a shell, wherein vent holes are distributed at the bottom of the shell; a filter element hole is formed in the center of the bottom of the shell; a filter element is installed in the filter element hole; the filter element is formed by integrally sheathing an inner core and an outer core; air holes are formed on the side walls of the inner core and the outer core; the air holes are communicated with the inner cavity of the shell; and through holes are formed at the bottoms of the inner core and the outer core. The air pump muffler disclosed by the invention achieves three levels of filtering by adopting the inner core, the outer core and the shell and can be used for greatly reducing the noise.

Description

technical field [0001] The invention relates to a muffler, in particular to an air pump muffler. Background technique [0002] The air pump is one of the necessary safety equipment in coal mines. It not only supplies air to provide oxygen, but also discharges harmful gases or flammable and explosive gases from the underground. Therefore, the air pump needs to work continuously and uninterrupted. When working underground with a small roadway, the noise of the air pump is very loud, and the underground staff cannot communicate in a normal language. Most of them use gestures or whistles instead. In many cases, the meaning of the expression will be misunderstood or even make mistakes. , seriously affecting the normal work. Although the air pump itself has a muffler, its effect is not good. Contents of the invention [0003] The object of the present invention is to provide an air pump muffler capable of effectively reducing noise. [0004] The technical solution of the pres...
