Abstract

Disclosed is a lightweight multifunctional ear protection face shield (hereinafter abbreviated as "face shield") capable of reducing droplet infection. The face shield is combined with various locking structures to form the appropriate spacing and angle between the face shield and the face, avoiding contact between the face shield and the nose and mouth to facilitate air evacuation, and prevent fogging in the eye area from entering the vision. prevent the effects of Face shields can also be used in combination with masks. At the same time, at least ⅙ of the area of the face shield is printed with a pattern to form a mouth-nose and mask blocking and mood-regulating function.

Description

The present invention belongs to the field of protective equipment and extends to a kind of face shield.

Since droplets are one of the possibilities for treatment or transmission of epidemics, masks have become a must-have and hot-selling protective item. It has become a necessary measure during work and even in daily life. However, in terms of blocking the face and eyes, the mask has a weaker ability to block the eyes and face than the face shield, and cannot significantly reduce the threat of droplet infection like the face shield. And when wearing a commercially available head-mounted face shield, the headband on the face shield deforms the hairstyle, and at the same time, the commercially available face shield has the following problems: (1) The weight makes the wearer feel uncomfortable. Troubleshoot and apply pressure. (2) Since it is separate from the mask, putting on the mask and face shield at the same time will be a terribly complicated operation. (3) The masks on the market are environmentally harsh because they are made of different composite materials. (4) When the air temperature is low, the hot air breathed by the wearer of the face shield condenses inside the face shield, which has a relatively low temperature, and fogs up, affecting the line of sight and causing inconvenience in work. Further safety hazards may occur. (5) The specifications of commercially available face shields are too large and the specifications are single, so people do not want to purchase them independently and do not want to wear face shields willingly. Accordingly, there is a need to develop a face shield that is lightweight, easy to wear, environmentally friendly, anti-fogging, and more attractive.

An object of the present invention is to solve the above problems, and at the same time, the ear straps can reduce the pressure on the wearer.

To provide an extremely lightweight composite face shield which can be repeatedly worn by a user and can protect a mask and face.

SUMMARY OF THE INVENTION The present invention provides a face shield that protects a mask. This face shield has a slot, anti-falling structure, and split elastic straps to create a space between the mask and the face shield, making it easier for air to pass through and reducing fogging around the eyes.

SUMMARY OF THE INVENTION In accordance with the present invention, a face shield is provided. This face shield can protect the mucous membrane of the face, and the slot and anti-fall structure create a space and opening angle between the face shield and the face, allowing air to pass through easily and reducing fogging in front of the eyes.

SUMMARY OF THE INVENTION In accordance with the present invention, a face shield is provided. In addition to the ear strap structure for fixing the face shield, the lower half of the face shield has a "distance fixing isolation zone" that allows you to change the radian of the face shield. At the same time as reducing the open space between the face shield and the face, the face shield itself can secure the distance from the mouth and nose.

SUMMARY OF THE INVENTION In accordance with the present invention, a face shield is provided. In addition to the ear strap structure for fixing the face shield, the upper half of the face shield has a "distance fixing isolation zone" that allows you to change the arc of the face shield. The open space between the face shield and the forehead is reduced, and the face shield itself can secure the distance from the mouth and nose. And a face shield and a baffle near the forehead reduce the risk of face contact with airgel.

According to the present invention, one or more slots are provided on both sides of the face shield through which the elastic straps pass, the elastic straps prevent the plastic sheet from sticking to the face, and secure the distance between the face shield and the face, Reduce the possibility of droplet transmission as much as possible.

In addition, the present invention can print various patterns on the basis of different mask shapes to beautify the face shield, prevent water vapor, and inspire people.

And in the situation of mask supply shortage in the market, the present invention uses a face shield to protect the mask and extend the service life of the mask. Furthermore, using only split elastic straps and using a face shield alone reduces the possibility of droplet infection.

The gist and scope of the present invention and specific examples will be described in more detail below with reference to the drawings. For ease of explanation, it should be understood that the drawings were not drawn perfectly to scale.

Example 1:
FIG. 1 is a rear view of a face shield embodying the present invention (the direction in which the inside of the face shield is seen from the wearer). The wearer passes through the anti-falling device 04 on both sides of the split elastic string 03 through the innermost slot/round hole with a diameter of 5 mm or less at both ends of the face shield, the split elastic string 03 itself remains inside the face shield, and the transparent sheet and face It acts as an insulating layer and helps keep perspiration from sticking to the seat and face.

The split ear straps go through the slots twice, through the outside of the face shield, and then over the ears. The ear straps are threaded twice through the slots and hung over the wearer's ears, keeping the face shield on the face and reducing ventilation.

Example 2:
FIG. 2 is a rear view of the face shield embodying the present invention (the direction in which the inside of the face shield is seen from the wearer). The wearer can easily position the outside of the mask toward the face shield. Both sides of the mask are near long slots inside the face shield, and the elastic straps 03 of the mask are pulled out of the face shield from the innermost long slots at both ends of the face shield. The face shield and mask are connected by mutual positioning of the ear straps and slots, and the wearer can easily put the mask and face shield together or put them down at the same time.

FIG. 3 is a rear view of the face shield embodying the present invention (the direction in which the inside of the face shield is viewed from the wearer). FIG. 4 is a bird's-eye view of a face shield embodying the present invention. As in the first embodiment, the wearer pulls out the elastic straps 03 of the mask from the innermost long slots at both ends of the face shield to the front of the face shield. After aligning the edge of the mask with the long slot, the ear straps are pulled upward and caught in a small hole or a cross-shaped non-slip structure on the long slot to avoid the ear straps from slipping. The length between the ear straps on both sides of the mask is smaller than the distance that the ear straps on both sides of the face shield can pass through the long slots. The face shield bends and separates from the mask. When wearing a face shield and mask, a space is created between the face shield and the mask, reducing the discomfort of stuffiness.
