Problems solved by technology

[0006] As far as the existing known technology is concerned, the filter material of the mask is generally fabric. The only way for this filter material to achieve high dust suppression efficiency is to increase the thickness and density, and the negative effect of increasing the thickness and density is that it will increase the dust resistance. Breathing resistance, so the air permeability is low, so when the user wears the mask, he will not breathe smoothly and feel uncomfortable

Embodiment Construction

[0071] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the filter structure proposed according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments. The instructions are as follows.

[0072] See figure 1 , Which is a schematic diagram of the filter structure of the first embodiment of the present invention; as shown in the figure, this embodiment provides a filter structure 1. The filter structure 1 includes a mask body 10 and a pleated layer 20. The pleated layer 20 has multiple Two folds 210 are arranged on the mask body 10. The mask body 10 is three-dimensional, and the fold layer 20 is also three-dimensional, such as figure 1 As shown, the mask body 10 and the wrinkle layer 20 of this embodiment are both cup-shaped, so the geometric shape (cup shape) of ...

Abstract

The invention relates to a filtering structure. The filtering structure comprises a face cover body and a fold layer. The fold layer comprises a plurality of folds and is arranged on the face cover body. The surface area of the fold layer is larger than the surface area of the face cover body. Thus, the filtering area of the filtering structure can be effectively enlarged, the filtering effect of the filtering structure is improved, and the breathability of the filtering structure is improved.

Description

Technical field [0001] The invention relates to a filtering structure, in particular to a filtering structure with good air permeability and filtering effect. Background technique [0002] Filtering structure has always been one of the daily necessities that people often use, such as masks. Nowadays, air pollution is getting more and more serious. Whether it is industrial exhaust gas or exhaust gas emitted by automobiles and motorcycles, it has a great impact on the environment. It also has a considerable impact on human health. Therefore, masks are an indispensable necessity for motorcyclists riding motorcycles. In addition, medical masks are also indispensable for medical treatment. For example, SARS and avian influenza epidemic viruses were prevalent several years ago. Because such viruses can cause death, the supply of masks was in short supply at that time. [0003] There are many types of masks nowadays, including paper masks, surgical masks, N95 masks and activated carbon m...
