Abstract

A breathing mask structure, comprising: the combination part is provided with the combination groove, and the elastic ring is fixed in the combination groove, and when the combination part is sleeved on the mask body through the elastic ring, the mask opening is affected by the elastic ring The elastic pressing of the elastic ring further uses the elastic force of the elastic ring to push the opening of the mask, so that the first buckle part is tightly fastened to the first buckle groove of the assembly to improve the bonding strength, and the elastic ring can pass through the mask body. The tight pressure can achieve the effect of effective air tightness, and the rigid structure of the assembly is used to produce the effect of facilitating the application of force by the hand, so that the combination groove of the assembly can be easily inserted into the mask opening of the mask body, that is, through the mask body. The assembly also achieves the function of easy disassembly and cleaning, and directly achieves the effect of stable airtightness after being installed.

Description

Respiratory mask structure

The present invention relates to a breathing mask structure

According to a conventional breathing mask structure, it includes a mask body and a cover body, the mask body is made of plastic material, the mask body is formed with a mask opening at one end, and a cover body is made of silicone material, the cover A ring is formed at one end of the body, and the cover body is fitted with the opening of the mask to form an airtight effect with the mask body through the elasticity of the silicone rubber. There are some shortcomings, the main reasons are as follows: the cover is used to cover the user's mouth and nose, so it is easily contaminated by sweat, moisture and saliva, and must be removed for cleaning after a period of use. Knowing that the mask body is directly removed for cleaning. Since the entire cover body is made of elastic body, it is difficult for the user to force the ring to fit the opening of the mask, and it is necessary to continuously press different parts of the mask body to gradually squeeze. After pressing it to an ideal position, the ring mouth can be easily deformed, so that the user cannot be sure whether it is completely installed, so there is a disadvantage that it is difficult to install the mask body back to the mask body after cleaning.

In view of this, the inventor of the present invention has been engaged in the manufacture, development and design of related products for many years, aiming at the above-mentioned goals, after detailed design and careful evaluation, finally came up with a practical invention.

The technical problem to be solved by the present invention is to provide a breathing mask structure in view of the above-mentioned deficiencies in the prior art.

A mask body is made of a hard material, and a mask opening is formed at one end of the mask body, and a plurality of first buckles are protruded from the mask body adjacent to the mask opening, and an assembly is made of a hard material, The assembly is recessed with a coupling groove along the opening shape of the mask, and an elastic ring is fixed in the coupling groove, and the assembly has a plurality of first buckle grooves at the coupling groove, and the assembly uses the coupling groove. The opening of the mask is sleeved, so that the first buckle portion is fastened and fixed in the first buckle groove, and the elastic ring is pressed by the opening of the mask to form an airtight and firm combination, and the assembly is attached to the first buckle groove. A ring groove is concavely formed on the opposite surface, and the assembly is provided with a plurality of second buckle grooves at the ring groove. A plurality of second buckle parts are protruded from the ring opening, and the cover body is inserted into the ring groove with the ring opening, and is fastened to the second buckle groove with the second buckle parts.

The elastic ring is made of silicone material, and is combined with the assembly by injection molding.

The mask body is protruded with a plurality of protruding strips on the outer surface, and the assembly penetrates the coupling groove to form a plurality of gaps, and the protruding strips are inserted into the gaps to form a limiting function.

The mask body is protruded with a buckle on both sides, and the buckles are connected with each other by an elastic band.

One end of the mask body is extended with an arm, and two hooks are formed at the end of the arm, and the two hooks are connected with each other with a belt.

An elastic pad is fixed at the end of the support arm.

The assembly is formed with an inner sidewall surface in the combining groove, and the elastic ring is attached and fixed to the inner sidewall surface.

The assembly is formed with a groove bottom surface in the combination groove, the groove bottom surface is surrounded by a positioning groove adjacent to the inner side wall surface, and the elastic ring extends a bottom ring, and the bottom ring is accommodated at the positioning groove The mask opening presses the bottom ring, and the bottom ring elastically pushes the first buckle portion against the first buckle groove.

The mask body and the assembly are both made of plastic material.

The first main purpose of the present invention is that the assembly is provided with the coupling groove, and the elastic ring is fixed in the coupling groove. The elastic extrusion of the elastic ring further utilizes the elastic force of the elastic ring to push the opening of the mask, so that the first buckle portion is tightly fastened to the first buckle groove of the assembly to improve the bonding strength, and the mask body can also pass through the mask body. The tight pressure of the elastic ring achieves the effect of effective airtightness, and when the cover needs to be removed for cleaning, the assembly can be removed together, and the hard structure of the assembly can be used to facilitate hand force after cleaning. The effect of this is that the combination groove of the assembly can be easily inserted into the mask opening of the mask body, and the ideal airtight effect can be achieved by the cooperation of the elastic ring and the mask opening. The result is that the assembly can be easily disassembled and cleaned at the same time, and the effect of stable airtightness can be achieved directly after the assembly is installed.

The second main purpose of the present invention is that the coupling groove is formed with an inner sidewall surface and the groove bottom surface, and the positioning groove is further recessed on the groove bottom surface, and the elastic ring is directly fixed on the inner sidewall surface and the groove bottom surface by injection molding. The positioning groove forms a firm joint state, and the bottom ring of the elastic ring protrudes from the bottom surface of the groove, thereby providing a space for extrusion and deformation to the bottom surface of the groove, so as to ensure the effective structural strength under the condition of sufficient structural strength. Improve its elasticity and air tightness.
