The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 4, a noise reduction filter structure includes a filter element 1, a support member 2 sleeved on an outer ring of the filter element 1, and a sound absorption member 3 disposed on one side of the filter element 1; the filter element 1 is used as a conventional air filtering material, and various filter element 1 materials on the market such as asbestos and the like can be adopted according to actual requirements and different characteristics of the filter element 1 materials. This embodiment is in order to increase noise reduction effect in the air inlet department of filter, one side at filter core 1 sets up inhales sound piece 3 (inhale sound piece 3 in this embodiment can be by the sponge, the asbestos, the foam, materials such as organic fiber constitute, can select according to actual need and cost, the corresponding sound effect of inhaling of homoenergetic reaching material, and consider the density of different materials simultaneously, need to guarantee not causing the influence to air cleaner's the admitting air, and be located filter core 1 and keep away from support piece 2's one end, and inhale and set up a plurality of sound absorption posts 4 on the terminal surface of sound piece 3 one end dorsad filter core 1.

Each sound absorption column 4 in this embodiment all is hemispherical structure, and each sound absorption column 4 and inhale the setting of sound between 3 and be four prismatic table column structure supporting seat 5 (the material of supporting seat 5 can with sound absorption column 4, inhale the material of sound 3 the same, convenient processing, production, integrated into one piece), through the different structures of sound absorption column 4 and supporting seat 5, the cooperation of length, and inhale the surface of sound 3, the three can be in the use, absorb, the noise that the filtration comes from the different wave bands that external and air cleaner inside propagation comes, sound absorbing effect is obvious.

Considering that the filter element 1 and the sound absorbing material are usually made of soft materials, in this embodiment, the support member 2 is disposed outside the filter element 1 and is made of hard materials, or can be replaced by a plastic-coated member, and the support member 2 has a circular ring structure and is matched with the filter element 1; one end of the support piece 2 facing the sound absorption column 4 is provided with a clamping groove 9, and the axial section of the support piece 2 is in a structure like a Chinese character 'ji', so that the support piece 2 can be clamped at the port of the air inlet pipe of the air filter like a cover mounting mode when being mounted, and the mounting mode is simple and rapid.

Meanwhile, the annular positioning groove 11 for embedding the support member 2 is formed in the outer circumferential surface of the filter element 1, so that the support member 2 and the filter element 1 are assembled.

In order to further improve the sound effect of this embodiment, avoid the draw-in groove 9 of hard material to increase the transmission of sound wave, this embodiment intussuseption in draw-in groove 9 is inhaled sound cotton 7, and inhales the surface of sound cotton 7 and has laid a plurality of sound of inhaling protrudingly 8, and respectively inhale protruding 8 staggered arrangements of sound, utilize the material characteristic of inhaling sound cotton 7, and respectively attract absorption, the interference of bellied sound wave, avoid the sound wave to propagate through draw-in groove 9.

Simultaneously, this embodiment has all seted up a plurality of sound holes 6 of inhaling on the surface of sound column 4 and supporting seat 5, through inhaling seting up of sound hole 6, can further improve this embodiment to the absorption of the inside noise of air cleaner, makes the not absorbed sound wave transmit each other, offset between each sound column 4 and supporting seat 5 of inhaling, will pass to the noise volume of external world and minimize. In addition, the end surface of the sound absorbing piece 3 opposite to one end of the sound absorbing column 4 can be designed into a concave arc surface structure, so that the surface area of the position is increased, and the sound absorbing and noise reducing effects of the position are further improved.

This embodiment easy dismounting only needs to inhale sound piece 3 towards air cleaner's inside, utilizes draw-in groove 9 on the support piece 2, the card in the mouth of pipe of intake pipe can, there is filter core 1's existence, inside the particle impurity that has still reduced external major possession was inhaled air cleaner, the life of extension equipment.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
