Referring to the attached drawings, the face frame comprises a face frame body 1 capable of covering the mouth and nose, a first bag body 2 used for pressing a mask on the face of a human body is arranged on the edge of the periphery of the face frame body 1, a breathing passage 9 used for air to enter and exit is arranged in the middle of the face frame body 1, a cavity is formed in the first bag body 2, the face frame body 1 is connected with the first bag body 2, a nose groove 11 avoiding the bridge of the nose is formed in the face frame body 1, the face frame body 1 is provided with an installation structure used for being connected with a rope or an elastic belt sleeved on the head, and the face frame body 1, the first bag body 2 and the mask and the face of the human body are sequentially placed from outside to inside.
Preferably, the face frame body 1 further comprises goggles for covering eyes, a second bag body 5 is arranged at the edge of each goggle, a cavity is formed inside each second bag body 5, and the face frame body 1 is connected with the second bag bodies 5. The face frame body 1 comprises a part for covering eyes and a part for covering mouth and nose. The face frame body 1 is a transparent plane body with equal thickness at the part right in front of eyes.
Preferably, the face frame body 1 is further provided with an external structure for fixing and placing the glasses at the goggles, if the external structure is provided with an outer groove 8, the external structure comprises the outer groove 8, and the outer groove 8 and the second capsule 5 are respectively arranged on two sides of the face frame body 1. This is to facilitate the lens placement in the outer groove 8 of this outer side by the person wearing the glasses at ordinary times. Thus, the spectacle frame is not worn, and the spectacle frame and the face frame body 1 can interfere with each other.
Preferably, face frame body 1 still is provided with the built-in structure who is used for the fixed glasses of placing at the goggles position, the built-in structure includes screw post 6, lens clamp plate 15 passes through the screw connection on the screw post 6 with face frame body 1, screw post 6 sets up the homonymy at face frame body 1 with second utricule 5. This is convenient for the person wearing the glasses to place the lens in the lens pressing plate 15 fixed on the inner side. Thus, the spectacle frame is not worn, and the spectacle frame and the face frame body 1 can interfere with each other.
Preferably, the first capsule 2 and/or the second capsule 5 are filled with gas and/or liquid in the cavity thereof, and the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 5 at normal temperature and normal pressure is smaller than the maximum volume of the cavity thereof at normal temperature and normal pressure. For example, the maximum volume that can be filled inside the first capsule 2 means the volume of the first capsule 2 that can be filled with the maximum amount of water when the first capsule 2 is sealed at a temperature of 20 degrees celsius at a pressure of gas and/or liquid equal to one atmosphere inside the first capsule 2. When in use, the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 5 under normal temperature and pressure is smaller than the maximum volume of the cavity which can be filled under normal temperature and pressure. This is the case when said first and/or second capsule 2, 5 are non-elastic sealed capsules, if elastic, the volume of gas inside said first and/or second capsule 2, 5 is not certain and can fill the whole of said first and/or second capsule 2, 5. That is, if the first and/or second capsules 2, 5 are elastic, the gas and/or liquid may be under-filled, and the amount of inflation fluid and/or liquid may be selected to be one third to one half, or may be over-filled, or even over-head, such that the pressure in the first and/or second capsules 2, 5 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 first capsule 2 and/or the second capsule 5 may be gas, liquid, or liquid plus gas, and the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 5 refers to the sum of the volumes of gas and liquid, the volume of gas, the volume of liquid, and both the gas and the liquid. The liquid in the gas and/or liquid filled in the cavity of the first bag body 2 and/or the second bag body 5 comprises a high-molecular material, which can flow, high-elastic material or other soft solid materials, wherein the high-elastic material can also flow or deform to the other side under pressure, and the other soft solid materials comprise sponge, silica gel and the like.
Preferably, the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 5 at normal temperature and pressure is less than one third to one half of the maximum volume of the cavity at normal temperature and pressure. When in use, the volume of the gas and/or liquid filled in the cavity of the first capsule 2 and/or the second capsule 5 under normal temperature and normal pressure is one third to one half of the maximum volume of the cavity which can be filled under normal temperature and normal pressure, and the gas can be filled before sale or when being used by customers. For example, because the first and/or second bladders 2, 5 are not filled with gas, the first and/or second bladders 2, 5 can be inflated at the concave part of the human body under the action of small external force and deflated at the convex part of the human body, so that the mask body 1 is fully attached to the human body, and the complete sealing is realized. If the first and/or second elastic bag bodies 2 and/or 5 are elastic, the first and/or second bag bodies 2 and/or 5 can be filled with gas and/or liquid, but the external force required for making the face frame body 1 fully fit with the human body is relatively large. Of course, the volume of the gas and/or liquid filled in the cavity of the first and/or second bag 2, 5 at normal temperature and pressure may be other proportion, such as two thirds, of the maximum volume that the cavity can be filled at normal temperature and pressure.
Preferably, the first bag body 2 and/or the second bag body 5 are annular bodies with annular cavities in the middle in a tire inner tube shape or bag bodies with a plurality of bag bodies enclosed into an annular shape, and the middle of the first bag body 2 is provided with an air inlet and outlet channel.

Preferably, the gas and/or liquid with which the first capsule 2 and/or the second capsule 5 are filled in the cavities thereof is air. The gas and/or liquid in the first and/or second capsule 2, 5 may be a liquid with a high viscosity, so that the requirements on the material of the first and/or second capsule 2, 5 are not high, and water may be used, although it is preferable to use air, which is inexpensive, and the advantage of water is that some materials are permeable to air but impermeable to water. The material with air is more demanding than the material with water.
Preferably, the soft body part is connected with the face frame body 1 and the sealing capsule body 2 and is placed between the face frame body 1 and the first capsule body 2 and/or the second capsule body 5. The soft body part is formed by cutting out the part of the face frame body 1 close to the first capsule body 2 and/or the second capsule body 5 independently to form a part and is made of soft materials, and the soft body part can assist deformation to adapt to matching with the face.

The first and/or second bladders 2, 5 may be configured without inflation ports 13 or with inflation ports 13. The air pipe 14 is also connected with an air-entrapping balloon for air entrapping, a one-way valve is arranged between the air pipe 14 and an air outlet of the air-entrapping balloon, and a one-way valve is arranged at an air inlet of the air-entrapping balloon.
Preferably, said first capsule 2 and/or second capsule 5 are elastic capsules.
Preferably, the first and/or second capsule 2, 5 and the face frame body 1 are connected by a connecting belt 4, the connecting belt 4 includes a belt loop 20 for being sleeved on the periphery of the first and/or second capsule 2, 5, and a tail belt for being tied on the face frame body 1, and the circumference of the belt loop 20 is greater than the circumference of the cross section of the first and/or second capsule 2, 5. The tail band is connected with the face frame body 1 through the connecting band hole 10, and can be connected in an adhesive mode or in other modes.
Preferably, the first capsule 2 and/or the second capsule 5 may be provided as one capsule consisting of a plurality of small capsules.
Preferably, the gas and/or liquid filled in the cavity of the first bag body 2 and/or the second bag body 5 further comprises a high-molecular material or other soft solid materials which are in a high-elastic state at normal temperature, and the other soft solid materials comprise sponge, silica gel and the like.
Preferably, said first and/or second bladder 2, 5 is provided with a support strip against arching on the side of the face. This brace is intended to prevent the first 2 and/or second 5 bladders from having an arched channel that would allow viruses to enter the mouth when the first 2 and/or second 5 bladders are in facial engagement.
Through set up first utricule 2 and/or second utricule 5 at face frame body 1, gas and/or liquid in first utricule 2 and/or the second utricule 5 are full of the clearance fill between face frame body 1 and the gauze mask when face frame body 1 uses and keep certain pressure to first utricule 2 and/or second utricule 5 compress tightly the gauze mask and stop gas from getting in and out from the clearance between face and the gauze mask. The gas and/or liquid within the first capsule 2 and/or the second capsule 5 may be air or the like. The cost of using air is the lowest. The face frame body 1 can be made of transparent materials, so that the face can be seen clearly, and people can not be mistaken. The face frame body 1 can be made of hard materials, such as PC, ABS and PMMA.
In addition, the shape of the face frame body 1 is various, and the shape of the first capsule body 2 and/or the second capsule body 2 can be automatically adjusted to adapt to the gap between the face frame body 1 and the face when the face frame is used and is changed along with the designed shape of the face frame body 1, so that certain pressure can be filled and maintained. The first and/or second bladder 2 may be separately purchased from the outside and the first and/or second bladder 2 may be connected to the bezel body 1. Before use, the first bag body 2 and/or the second bag body 5 are inflated and sealed, and when the face frame body 1 is used, the gas and/or liquid in the first bag body 2 and/or the second bag body 5 fills the gap between the face frame body 1 and the mask and the face and keeps certain pressure, so that gas is prevented from entering and exiting from the gap between the face and the mask. Because the first bag body 2 and/or the second bag body 5 can completely fill the uneven part of the human face, the low pressure part of the first bag body 2 and/or the second bag body 5 can be automatically compensated, and the pressure of the first bag body 2 and/or the second bag body 5 on each side wall is equal. The first bag body 2 and/or the second bag body 5 can fill the gap between the human face and the face frame body 1, which is smaller than the maximum diameter formed by the gap, and as long as the gap is smaller than the specific maximum diameter, the first bag body 2 and/or the second bag body 5 block the gap to prevent air from entering and exiting. The maximum diameter that the first capsule 2 and/or the second capsule 5 can assume is the diameter of a cylinder that the first capsule 2 and/or the second capsule 5 can assume by the pressure in its cavity being greater than the local atmospheric pressure. When the face frame is not used, the air in the first bag body 2 and/or the second bag body 5 is exhausted, and the face frame occupies a small volume in the storage or transportation process.
When the first bag body 2 and/or the second bag body 5 are provided with the inflation holes 13, the first bag body 2 and/or the second bag body 5 can be inflated and sold according to the inflation requirements of the first bag body 2 and/or the second bag body 5 without the inflation holes 13 when the face frame is sold, the face frame can also be sold without inflation, the face frame is self-inflated when a user uses the face frame, the first bag body 2 and/or the second bag body 5 are folded and divided into two halves when the face frame is used, one half of the face frame is compressed and is not inflated, the other half of the face frame is inflated with gas, and the compressed half is released, so that the whole bag body is inflated with half of the gas.
Fig. 1 and 2 show that the face frame body 1 only has the mouth and nose parts, and at the moment, one capsule body is designed simply and can be used by both the person wearing glasses and the person not wearing glasses, fig. 3 and 4 show that the face frame body 1 comprises the goggles, and at the moment, a capsule body needs to be added under the goggles, so that the face frame is suitable for the person not wearing glasses to use, and the person wearing glasses can use the face frame shown in fig. 5 and 6, and the hanging rod of the glasses hung on the ears avoids contacting with the glasses frame by the capsule body, and can also realize sealing. As for the internal and external structures of the visor portion, it is necessary to remove the lenses from the frame and place them thereon.
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 adding the bag body on the face frame, and the bag body is made of plastic film, so that 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.
