Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

For further explanation of the embodiments, the drawings are provided as part of the disclosure and serve primarily to illustrate the embodiments and, together with the description, to explain the principles of operation of the embodiments, and to provide further explanation of the invention and advantages thereof, it will be understood by those skilled in the art that various other embodiments and advantages of the invention are possible, and that elements in the drawings are not to scale and that like reference numerals are generally used to designate like elements.

Referring to the attached drawings, the oral-nasal mask comprises a mask body 1 capable of covering the oral-nasal part, wherein the mask body 1 is provided with breathing holes 3 for air to enter and exit, the peripheral edge of the mask body 1 is provided with a sealed capsule body 2 which is used for being in direct or indirect contact with the face of a human body, a cavity is arranged inside the sealed capsule body 2, and the mask body 1 is connected with the sealed capsule body 2.

Preferably, the cavity of the sealed capsule body 2 is filled with gas and/or liquid, and the volume of the gas and/or liquid filled in the cavity of the sealed capsule body 2 at normal temperature and normal pressure is smaller than the maximum volume of the cavity which can be filled at normal temperature and normal pressure. For example, the maximum volume that can be filled inside the sealed capsule 2 means the volume of the sealed capsule 2 when the pressure of gas and/or liquid inside the sealed capsule 2 is equal to one atmosphere and the temperature is 20 degrees celsius, that is, the maximum volume of water that can be filled inside the sealed capsule 2. When in use, the volume of the gas and/or liquid filled in the cavity of the sealed capsule body 2 under normal temperature and normal pressure is smaller than the maximum volume of the cavity which can be filled under normal temperature and normal pressure. This is the case if the sealed capsule 2 is a non-elastic sealed capsule, and if it is elastic, the volume of gas inside the sealed capsule 2 is not certain and the whole sealed capsule 2 can be filled. That is, if the sealed capsule 2 is elastic, the gas and/or liquid therein may be under-filled, and the under-filling may also include that the amount of inflation gas and/or liquid is selected to be one third to one half, or may be over-filled, or even over-head, so that the pressure in the sealed capsule 2 is greater than a standard atmospheric pressure. Normal temperature and pressure mean a standard atmospheric pressure and a temperature of 20 ℃. For example, the gas and/or liquid filled in the cavity of the sealed capsule 2 may be gas, liquid, or liquid plus gas, and the volume of the gas and/or liquid filled in the cavity of the sealed capsule 2 refers to the sum of the volumes of gas and liquid, the volume of gas if gas, the volume of liquid if gas, and the sum of the volumes of gas and liquid if both gas and liquid are present. The gas and/or liquid contained in the cavity of the sealed capsule 2 comprises a flowable, high-elastic material of high-molecular material, which is also flowable or deformable under pressure to the other side.

Preferably, the volume of the gas and/or liquid filled in the cavity of the sealed capsule body 2 at normal temperature and normal pressure is less than one third to one half of the maximum volume of the cavity at normal temperature and normal pressure.

The sealing bag body 2 and the mask body 1 can be connected in an adhesive mode, and a belt can be arranged to wrap the sealing bag body 2 and then be fixed to the mask body 1. When the mask is used, the specially-made filter component 6 can be used, the filter component 6 is simple in structure and rapid to produce, and can be produced in large quantities in a short time, when the filter component 6 is used, the soft rubber ring 4 is placed in the soft rubber ring boss 24 in the surrounding bone 7, then the filter component 6 is placed, then the soft rubber ring 4 is placed, and then the breathing hole plug 5 is sleeved for pressing, so that outside air can only pass through the filter component 6 but not through a gap between the filter component 6 and the mask body 1, and the soft rubber ring 4 is sealed. By using the mask, the existing medical shell mask can be directly used and sleeved on the surrounding ribs 7, and then the medical shell mask is fastened by the elastic belts, and the medical shell mask can be sealed and cannot fall off due to the annular bulges or the threads arranged on the surrounding ribs 7, so that the medical shell mask can be butted with the original product. Use this face guard, can also directly use current medical shell gauze mask on the breather plug 5, because breather plug 5 has flexible glue ring 4 to seal with face guard body 1, be provided with breather plug ring 21 on the breather plug 5, when covering medical shell gauze mask on breather plug 5, breather plug ring 21 is the flexible glue preparation, just can seal medical shell gauze mask to can not drop, also can dock with original product like this.

Preferably, the gas and/or liquid filled in the cavity of the sealed capsule body 2 is air. The gas and/or liquid in the sealed capsule 2 may be a liquid with high viscosity, so that the requirement for the material of the sealed capsule 2 is not high, and water may be used, and it is better to use air, so that the cost of using air is low, and the advantage of using water is that some materials can be air-permeable but water-impermeable. The material with air is more demanding than the material with water.

When sealed utricule 2 is provided with the hole of aerifing 9, sealed utricule 2 can aerify the back and sell according to the sealed utricule 2's of no hole of aerifing requirement when the gauze mask is sold, also can not aerify and sell, aerify by oneself when for the user uses, when the gauze mask will be used, divide into two halves to sealed utricule 2 fifty percent discount, half compresses tightly and can not fill gas, and half is full of gas, loosens that half that compresses tightly, then whole utricule has just filled half gas.

Because the mask is disposable, it is not cost-effective to make a good sealing structure on the mask, but the sealing can be realized by using the capsule body which is made of plastic film, so the cost is very low. The function of the capsule can also be replaced by soft materials such as silica gel and the like, but the cost is high, the cost is not cost-effective, and the best effect is achieved by the capsule. When the mask is worn, the isolation is equivalent to the isolation from the outside, the isolation can replace the isolation at home, people still work as usual without closing villages, the influence of respiratory infectious diseases on the economy is greatly avoided, the medical expense is saved, and the national health level is improved.

In one embodiment, the material of the sealed capsule 2 is provided as a poor conductor of heat to prevent the human body from feeling cold.

In a particular embodiment, the sealing bladder 2 may be provided as a multilayer sealing bladder, although more preferably, the multilayer sealing bladder is stacked from the face to the mask.

In a particular embodiment, the sealing bladders 2 can be arranged in a plurality of rows, divided into an inner row and an outer row, with the same effect, but preferably, the plurality of rows means a plurality of rows of sealing bladders, like mosquito coils, but with only one layer between the face and the mask.

In a particular embodiment, the sealing bladders 2 may be provided as a plurality of rows of sealing bladders and as a plurality of layers of sealing bladders.

In a particular embodiment, the sealed capsule 2 may be provided as a soft material instead, such as silicone.
