Description

Protection face screen of splash function is prevented in filtration

Technical Field

The utility model belongs to the technical field of human protection, concretely relates to protection face screen of splash function is prevented in filtration.

Background

Since the epidemic situation of coronavirus pneumonia in the early 2020, 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 utility model aims to provide a protective face screen with the function of filtering and preventing splashing, which can solve the problem of side leakage of gas of the existing mask, can play the role of preventing splashing and protecting eyes while continuously providing clean air for a user, and effectively prevent the infection of spray; 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 realize the purpose, the utility model discloses the technical scheme who takes does:

the utility model provides a protection face screen of splash function is prevented in filtration, 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 the edge of buffering sealing washer 1 and 3 inside walls of transparent face screen, transom 4.

The buffer sealing ring 1 and the buffer sealing interlayer 8 are made of elastic materials, and the elastic materials comprise medical silica gel or rubber.

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 utility model has the advantages 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.

To sum up, the utility model has the advantages of simple structure, high-efficient practical, protective properties is strong and economy is practiced thrift, accords with national resources cyclic utilization's policy, can form the product rapidly and solve the urgent need at present.
