AI Technical Summary

Problems solved by technology

However, if the size of the filter is increased to increase its surface area, the filter blocks the user's view, making it difficult for the user to perform his work
Also, for example, a fiber filter may be partially folded or bent if the filter comes into contact with an object

Embodiment Construction

[0024] Exemplary embodiments according to the present invention will be described below with reference to the accompanying drawings.

[0025] figure 1 is a perspective view illustrating a fiber filter of the present invention, figure 2 is a perspective view illustrating an insert-type frame made of synthetic resin used as a space holding member of a fiber filter according to an embodiment of the present invention.

[0026] refer to figure 1 and figure 2 , The fiber filter of the present embodiment is a jacket-shaped filter in which filter cloths are overlapped with each other to form a front side and a rear side, and a frame made of synthetic resin is inserted into a space between the front side and the rear side.

[0027] The filter cloths 11 on the front and rear sides may be constructed by folding the filter cloth and sealing the edges of the two overlapping portions formed by the folding.

[0028] The filter cloths 11 on the front and rear sides are constructed with ...

Abstract

A filter for a mask in which a fibrous filter is folded into filter fabrics such that an outer layer faces external air while the edge portions thereof are sealed to form a shape like an envelope, and which is provided with a connection unit for making a connection with facial fittings of the mask, the filter including a space maintainance member in a space between the overlapped layers of the filter in order to secure a passageway for air to flow towards the connection unit. A mask including facial fittings having an air intake hole connected with the filter by the connection unit and defining a closed space near a mouth or a nose of a user's face when coming close to the mouth or the nose.

Description

technical field [0001] The present invention relates to an air filter for filtering toxic chemicals or dust particles, and more particularly, to a portable face mask. Background technique [0002] A face mask is an air filter used to prevent toxic substances in the air, such as dust particles, toxic chemicals, bacteria, etc., from entering the human respiratory organs. Masks are divided into facial fiber masks and detachable filter masks. The facial fiber mask consisting only of filter fibers basically covers the respiratory organs of the face, such as the mouth or the nose, so that the user can breathe the outside air through the facial fiber mask. A detachable-filter mask includes a face securement and a filter such as a purification module detachable from the facial securement. Based on the filtering target, masks can also be divided into dust masks and gas masks. [0003] Although facial fiber masks are usually used as dust masks, detachable filter masks can also be u...
