Description

Portable core-changeable mask

Technical Field

The invention relates to a protective mask, in particular to a portable core-replaceable mask which can replace a filter core and is convenient to carry.

Background

At present, most of known protective masks are disposable protective masks and air valve protective masks, wherein the disposable protective masks are convenient to carry, but the limited use times are relatively wasted. While the air valve type protective mask can be used for a long time, the fixed air valve and the semi-hard shell type mask are inconvenient to carry.

Disclosure of Invention

In order to overcome the defects that the existing protective mask is inconvenient to carry about and can not be used for a long time, the invention provides the portable core-changing mask, which can prolong the service life by changing a filter core and realize the purpose of carrying about by folding and contracting.

The technical scheme adopted by the invention for solving the technical problems is as follows: the invention comprises a supporting seat, a ventilating cover, a filter element, a face mask, a sealing ring, an elastic band, a hinge and an air valve.

The face mask is a triangular cone-shaped cup type structure formed by a left side surface, a right side surface and a bottom surface, and is made of an airtight material. The left side surface and the right side surface of the mask are respectively provided with a left through hole and a right through hole, the periphery of the cup mouth of the upper mask of the mask is provided with a sealing ring, and the sealing ring is of an annular tubular structure which is made of elastic materials and is matched with the facial contour of the periphery of the mouth and the nose of a human body. The pipe wall at the lower end of the sealing ring is connected with an air valve which is a dual-purpose valve structure of inflation and deflation. The supporting seat is composed of a cylinder and an annular plate connected to the upper end opening of the cylinder, threads are arranged on the outer cylinder wall of the cylinder on the supporting seat, the left supporting seat and the right supporting seat are arranged in parallel and connected through hinges, and the left end head of the left supporting seat and the right end head of the right supporting seat are respectively connected with the left end head and the right end head of the elastic band. The left and right supporting seats are arranged on the outer side of the face mask, and two inner holes of the left and right annular plates on the left and right supporting seats are respectively in butt joint with two through holes on the face mask. The ventilation cover is a circular cover body structure which is formed by a cylinder and a circular plate connected to the upper end opening of the cylinder, a plurality of ventilation holes are formed in the circular plate of the ventilation cover, and threads are formed in the inner cylinder wall of the cylinder on the ventilation cover. The filter core is the circular sheet structure with ventilative lid's hole matched with, the filter core make by the material of filtration air impurity. The two filter elements are respectively arranged in the left and right ventilating covers which are respectively connected with the left and right supporting seats through threads, and the filter elements are positioned between the circular plate on the ventilating cover and the annular plate on the supporting seats.

When the mask is used, air is blown into the sealing ring through the air valve, and the mask can be opened when the sealing ring is inflated and expanded. The cup mouths of the mask are aligned to the mouth and nose positions of a user, and when the sealing ring is completely attached to the skin around the mouth and nose of the user, the elastic band can be sleeved behind the brain of the user, and the mask is fixed accordingly.

When the mask is stored, the air valve is opened, and the elastic sealing ring can automatically contract and simultaneously furl the mask. The left and right supporting seats are folded around the hinge, and the partially exposed mask is plugged into the box body formed by the left and right supporting seats, and finally the elastic band is wound on the left and right breathable covers.

The portable water filter has the advantages that the service life can be prolonged by replacing the filter element, and the portable water filter can be carried by folding and contracting.

Detailed Description

In fig. 1, 2, 3, 6 and 7, the face mask 4 is a triangular-cone-shaped cup structure formed by a left side surface, a right side surface and a bottom surface, and the face mask 4 is made of an air-impermeable material. The left side surface and the right side surface of the face mask 4 are respectively provided with a left through hole and a right through hole, a sealing ring 5 is arranged along the periphery of the cup mouth of the upper face mask 4, and the sealing ring 5 is an annular tubular structure which is made of elastic materials and is matched with the facial contour of the periphery of the mouth and the nose of a human body. An air valve 8 is connected on the pipe wall at the lower end of the sealing ring 5, and the air valve 8 is of an air inflation and deflation type dual-purpose valve structure. The supporting seat 1 is composed of a cylinder and an annular plate connected to the upper end opening of the cylinder, threads are arranged on the outer cylinder wall of the cylinder on the supporting seat 1, the left supporting seat 1 and the right supporting seat 1 are arranged in parallel and connected through a hinge 7, and the left end head of the left supporting seat 1 and the right end head of the right supporting seat 1 are respectively connected with the left end head and the right end head of the elastic band 6.
