Description

Protection face screen with gas filtering capability

Technical Field

The invention belongs to the technical field of human body protection, and particularly relates to a protective face screen with a gas filtering function.

Background

Since the occurrence of new coronavirus epidemic situation, various masks and protective screens become necessities of medical workers, even ordinary people; even if the existing mask is of the N95 grade, both sides of the nose wing, cheeks and chin of the existing mask have air leakage, and along with breathing, a part of air flow always passes through the most unobstructed gap, so that the filtering effect in actual use is lower than that in laboratory detection; moreover, when people only wear the mask, the infection probability can be caused by the contact of the spray with eyes, if the mask and the splash-proof goggles are worn, the wearing and the taking off are troublesome, and especially, medical workers need to spend more time to wear protective articles; the market needs a product that can be worn and taken off easily and simultaneously protect the nasal cavity and eyes, and the product is tightly attached to the face of a person, so that the cleanliness of inhaled gas is ensured by the filtering layer to the maximum degree of airflow.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention aims to provide a protective face screen with a gas filtering function, which can solve the problem of gas side leakage of the existing mask, can play a role of splash prevention and eye protection while continuously providing clean air for a user, and effectively prevent droplet infection; the dressing and the taking off are convenient, and the sterilization and the repeated use can be realized; the novel protective device has the advantages of simple structure, high efficiency, practicability, strong protective performance, economy and saving, accords with the policy of national resource recycling, and can quickly form a product to solve the immediate urgency.

In order to achieve the purpose, the invention adopts the technical scheme that:

the utility model provides a protection face screen with gas filtering capability, includes buffering sealing washer 1, be equipped with transparent face screen 3 in the middle of buffering sealing washer 1, transparent face screen 3 both sides are equipped with fixed band 2, and the lower part is equipped with transom 4 in the transparent face screen 3, and the sealed interlayer 8 of buffering is equipped with on buffering sealing washer 1 and the 3 inside walls of transparent face screen, transom 4 reason.

The buffer sealing ring 1 and the buffer sealing interlayer 8 are made of elastic materials.

The ventilation window 4 comprises a clamping groove 5 which is fixedly integrated with the buffer sealing ring 1, a replaceable sterile filter sheet 6 and a detachable clamping strip 7 which is embedded in the clamping groove 5.

The ventilation window 4 may be provided in plurality, at least one.

The size of the sterile filter sheet 6 is larger than or equal to that of the clamping groove 5.

The invention has the beneficial effects that:

1. the buffering sealing ring 1 made of the elastic material can be attached to the face of a user, and the situation that the protection is not tight due to side leakage is prevented. Buffer seal interlayer 8 can laminate user's face, wears two spaces about forming between transparent face screen 3 and the people's face in back, prevents that exhaled gas from blocking the water smoke of sight on transparent face screen upper portion formation.

2. The transparent panel 3 can conveniently observe external things while effectively blocking external pollution.

3. The ventilation window 4 is fixed on the ventilation window through the matching of the clamping groove 5 and the clamping strip 7, and the sterile filter sheet 6 is used for blocking and filtering external polluted air.

4. The sterile filter sheet 6 can be replaced, and the face screen can be reused after being disinfected, so that the sterilization device is economical and economical.

In conclusion, the invention has the advantages of simple structure, high efficiency, practicability, strong protective performance and economy, accords with the policy of national resource recycling, and can quickly form a product to solve the immediate urgency.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1 and 2, a protective face screen with gas filtering function, including buffering sealing washer 1, be equipped with transparent face screen 3 in the middle of buffering sealing washer 1, transparent face screen 3 both sides are equipped with fixed band 2, and transparent face screen 3 middle and lower part is equipped with transom 4, and buffering sealing spacer 8 is equipped with on buffering sealing washer 1 and 3 inside walls of translucent cover, transom 4 reason, can avoid the gas of mouth nose exhalation to form water smoke on the transparent face screen of eye, blocks the sight.

The buffering seal ring 1 and the buffering seal interlayer 8 are made of elastic materials and can be tightly attached to the face, so that external pollutants are effectively blocked.

Referring to fig. 3, the ventilation window 4 includes a clamping groove 5 fixed with the buffer sealing ring 1, a replaceable sterile filter sheet 6 and a detachable clamping strip 7 embedded in the clamping groove 5.

The ventilation window 4 can be provided with a plurality of at least one ventilation window, so that the ventilation property can be improved while the polluted air is effectively blocked.

The working principle of the invention is as follows:

when the face screen fixing band is used, the face screen is pressed close to a proper position of the face, the face screen fixing band is sleeved at a fixed position behind the head, and after the use is finished, the fixing band is taken off upwards from the back of the head, so that the face screen is separated from the face; wherein transom 4 compresses tightly aseptic cassette 6 through the cooperation of draw-in groove 5 with card strip 7 and is fixed in 4 windows of transom, and the separation filters outside polluted air, separates draw-in groove 5 and card strip 7, can take off used aseptic cassette 6, changes after new aseptic cassette 6, compresses tightly draw-in groove 5 and card strip 7 fixedly once more, and used repeatedly after the protection face screen can disinfect.

The above embodiments are only intended to illustrate the technical solutions of the present invention, but not to limit the same, and it should be understood by those skilled in the art that the technical solutions described in the foregoing embodiments can be modified or some technical features can be equivalently replaced, and the modifications or the replacements do not make the essence of the corresponding technical solutions depart from the scope of the present invention.
