Description

Breathable filter device with cloth coating

The present invention relates to a respiratory filtration device, and more particularly to a respiratory filtration device coated with a cloth.

With the recognition of diseases and the general level of health education, various types of masks have become one of the indispensable items in people's lives. In order to effectively prevent people from inhaling harmful substances in the air, most types of masks are stacked with a plurality of layers of filter membranes. However, people wearing such a multi-layered mask are prone to sultry feelings, but will reduce people's willingness to wear masks. In addition, since the masks are mostly active inhalation and exhalation, the mask of the multi-layer filter membrane relatively increases the force when inhaling, so that the general inspiratory volume without the mask can be achieved, so the above problems remain to be solved.

In the prior art, for example, the Republic of China New Patent Publication No. M481748 provides a "breathing filter device" having a filter module, a connecting bend, an adjustable bend and a mask assembly. The user can directly extend the gap between the free end of the adjustable bend and the free end of the connection bend by rotating the adjustable bend to directly wear the respiratory filter device on the shoulder or head of the user. In order to carry this breathing filter device for various tasks. The above creation provides the filtered air to the user through the filter module, and overcomes the difficulty of sultry heat and inhalation, however, since the adjustable bend and the connecting bend are made of hard plastic, once worn, The user's head and neck are quite large and awkward. In addition, although the connecting curved portion and the adjustable curved portion are arc-shaped, they cannot be adjusted to the shoulder according to the shoulder shape of different users, and the excessively large volume is reduced, thereby reducing the user's willingness to wear. .

In view of this, how to reduce the volume of the respiratory filter device carried by the shoulder to increase the user's willingness to wear, the prior art needs to be improved.

In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a breathing filter device with a fabric covering, which is covered by a cloth and supported by a user's shoulder by a flap to reduce the burden on the user. effect.

In order to achieve the above-mentioned creative purposes, the technical means employed in the present invention is to provide a breathable filter device having a fabric covering, comprising a filter, a cloth assembly and a mask assembly. The filter comprises an air outlet and an air inlet connected to each other. The cloth assembly includes a bag body and two flaps. The bag body comprises a top end, a bottom end and a through hole; the top end forms an opening; the bottom end is opposite to the top end, the bottom end is a closed end, and the top end forms a first portion with the bottom end An accommodating space; the first accommodating space is in communication with the opening of the top end to partially cover the outer side of the filter; the perforation is corresponding to the air inlet of the filter disposed in the first accommodating space . Each of the fins includes an engaging end and a free end; the engaging end is engaged with the top end of the bag body to connect the flaps to the bag body; the free end is opposite to the engaging end and at the engaging end A second accommodating space is formed between the second accommodating space and the first accommodating space of the bag body. The mask assembly includes a connecting tube and a mask; the connecting tube is disposed in the second receiving space of any one of the flaps, and one end of the connecting tube is filtered with the first receiving space disposed in the bag body The air outlet of the device is connected, and the other end of the connecting tube is passed through the free end of the airfoil; the mask has an exhalation space, and the mask is connected to one end of the free end of the connecting tube and the fin Connected.

Preferably, each of the flaps of the fabric assembly further includes a weight, and the weight is disposed in the second accommodating space and adjacent to the free end.

Preferably, one of the fins further includes a through hole, and the through hole is disposed at the free end and the connecting tube is disposed through the through hole.

Preferably, the bag body further comprises a cover body formed by extending the top end of the bag body, and the cover body can close the opening at the top end.

More preferably, the cover body is provided with a connecting member, and the top end of the bag body is provided with a joint member which is detachably connected to the joint member.

Preferably, the free ends of the fins comprise a fastener, and the fasteners are detachably coupled to each other.

Preferably, each of the fins further includes a support member disposed in the second accommodating space and interposed between the engaging end and the free end.

More preferably, the support member is a wire, a plastic sheet or a plastic elbow.

The advantage of this creation is that the fabric-covered breath filter device of the present invention is used to cover the filter and the two flaps are supported on the shoulder of the user to reduce the burden on the user, thereby making the creation lighter. Clumsy and increase the willingness of users to wear.
