Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1 to 5, a mask includes a mask body 1; the mask body 1 is of a flexible integrally-formed structure; the mask body 1 is provided with a breathable zone 11; the breathable fixed cover 2 is detachably arranged on the breathable area 11; a filter layer is arranged between the fixed cover 2 and the breathable zone 11.

It should be noted that, in the actual sale process, there may be no filter layer attached to the product, which may be purchased separately by the user. However, whether the final product is attached with a filter layer or not, if the mask body and the fixed mask structure are adopted, the protection scope of the scheme is considered.

The gauze mask body 1 of this embodiment is flexible integrated into one piece structure, and this structural feature can injection moulding obtain, and the cost of manufacture is low, and this structure can also guarantee with the facial laminating nature of user, improves sealed effect, and simultaneously, but this gauze mask's filter layer user DIY, and the material is few, can effectively reduce the filter layer cost. The mask body 1 can be repeatedly used, cleaned and disinfected, and has low manufacturing cost. The mask can effectively reduce the purchase and use cost of users.

After purchasing the product, a user needs to additionally purchase a filter layer, and the user of the filter layer can set three or more layers, such as four or five staggered layers of non-woven fabrics and melt-blown fabrics. The user cuts the filter layer into a structure with the same shape as the ventilation area 11, and then places the filter layer at the position of the ventilation area 11, and fixes the filter layer with the fixing cover 2. The fixing cap 2 should match the shape of the ventilating zone 11 as much as possible. The filter layer is replaced again after the filter is used next time. In this case, the filter layer material is few, and user's reuse cost is low. The mask body 1 can be used repeatedly, and can be cleaned and sterilized repeatedly.

Preferably, the filter layer is composed of a first non-woven fabric layer, a melt-blown fabric layer and a second non-woven fabric layer which are sequentially overlapped. Of course, the meltblown layer and the nonwoven layer are not limited to more layers and may be freely disposed according to the user's needs.

The filter layer can be any filter layer in the field, and the matching space between the fixing cover 2 and the ventilation zone 11 can be changed according to the thickness change of the filter layer.

In this embodiment, the ventilation zone 11 and the fixed cover are both provided with a plurality of hollow holes, and more preferably, the ventilation zone 11 is a protruding structure protruding out of the mask body 1; the fixed cover is clamped on the breathable zone 11. The shape of the breathable zone 11 may be circular, oval, square, triangular, etc.

Of course, in practical applications, the fixing cover may also be removable by a structure such as a screw connection, but this embodiment does not suggest this connection manner due to its flexible nature.

Preferably, the mask body 1 comprises a main body 12, connecting parts 13 arranged at two sides of the main body 12 and used for being connected with a lacing, and a fitting part 14 arranged at one side of the main body 12 close to the face of a human body; the fitting part 14 is a flexible fitting part 14 and is used for fitting the periphery of the mouth and the nose of the face of a human body; the breathable zone 11 is provided on the main body 12. The mask body 1 is integrally formed and flexible, and the mask body 1 is simple in structure and easy to demould.

In this embodiment, the main body 12 and the attaching portion 14 form an air buffer, and the attaching portion 14 is an annular ring disposed along one side of the main body 12 close to the human face; one side of the annular ring is a suspended side.

The edge design of annular circle can reduce the drawing of patterns degree of difficulty for the suspension side, and reduces gauze mask weight.

Preferably, the mask body 1 is made of TPU, and the thickness of any position of the mask body 1 is not more than 3 mm. It should be noted that the material of the mask body 1 in the present disclosure may be any optional plastic material that is harmless to human body and flexible. Because the present case adopts integrated into one piece technique, its thickness can be made very thin, and its weight can be made very light, and user's use feels good.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
