Abstract
The utility model relates to the field of respiratory protection, and discloses a medical power air supply protective mask with a face shield fogging prevention function. The medical protective mask solves the problems that when the medical protective mask is used, a large amount of humid gas exhaled by a human body can cause the face shield to be fogged, and the sight of medical staff is blurred, and has the advantages of convenience in wearing and low cost.
Description
Technical Field
The utility model relates to the personal protection field and the medical field, in particular to a medical power air supply protective mask with a face shield fogging prevention function.
Background
The medical protective mask is used for providing safe and effective protection for a wearer, and in a real working environment, due to long-time work, a large amount of humid gas exhaled by a human body can cause face shielding fogging, so that visual influence and obstacle can be brought to a medical worker who wears the medical mask, and then work is hindered.
SUMMERY OF THE UTILITY MODEL
The utility model provides a medical power air supply protective mask with a function of preventing face shield fogging, and aims to solve the problems that when a medical protective mask is used in the prior art, a large amount of humid gas exhaled by a human body can cause face shield fogging and cause blurred vision of medical care personnel.
The utility model adopts the specific scheme that: the utility model provides a medical power air supply protective face mask with prevent face shield fogging function, the face guard includes the baffle, baffle one end is connected with the face shield, sets up the through-hole on this baffle.
The end face of the other end of the baffle is a circular arc-shaped end face.
And the end face is provided with a silica gel pad.
The bottom of the plate body of the baffle is provided with a groove, and a water absorption cotton sliver is placed in the groove.
The groove is a trapezoidal groove.
The number of the through holes is 3-5, and the through holes are uniformly distributed on the plate body of the baffle plate.
The face screen is connected with an elastic apron.
The baffle is obliquely and upwards arranged on the panel, and the included angle between the baffle and the panel is 100-120 ℃.
Compared with the prior art, the utility model has the following beneficial effects:
1. according to the utility model, the baffle is arranged on the face screen of the air supply protective mask, the baffle firstly contacts warm and humid gas exhaled by a human body, the temperature of the baffle is lower, water drops are generated on the inner side of the baffle, the exhaled humid gas is prevented from going further upwards, water mist is prevented from being generated on the face screen at the visual field, a clear visual field is provided for medical workers, and the problem that the face screen is fogged and the sight of the medical workers is blurred due to the fact that a large amount of humid gas is exhaled by the human body when the medical protective mask is used is solved.
2. The utility model is provided with three through holes which promote the circular flow of the gas from top to bottom and prevent the exhaled gas from gathering at the front end of the baffle.
3. The trapezoidal groove is formed in the bottom of the baffle, so that the water absorption cotton sliver can be clamped conveniently, the water absorption cotton sliver is prevented from falling off, and water drops condensed by exhaled air are adsorbed by the water absorption cotton sliver.

Wherein the reference numerals are respectively:
1. the helmet comprises a face screen, 2 an elastic apron, 3 a helmet body, 4 an air inlet pipeline, 5 a through hole, 6 a baffle, 7 a groove, 8 and a water absorption cotton sliver.
Detailed Description
The present invention will be described in further detail below with reference to the attached drawings, and it should be clearly understood herein that the described embodiments are not all embodiments, but are merely illustrative and not restrictive of the present invention.
The utility model provides a medical power air supply protective mask with a face shield fogging prevention function, wherein an air inlet pipeline 4 is arranged on a mask body 3 of the mask. The face guard includes baffle 6, 6 one end of baffle is connected with face screen 1, sets up through-hole 5 on this baffle 6. The end face of the other end of the baffle 6 is a circular arc-shaped end face. And the end face is provided with a silica gel pad. The bottom of the plate body of the baffle 6 is provided with a groove 7, and a water-absorbing cotton sliver is placed in the groove 7. The groove 7 is a trapezoidal groove, and a water absorbent cotton sliver can be placed in the trapezoidal groove to fall off. After a human body wears the protective mask, the baffle plate is firstly contacted with warm and humid air exhaled by the human body, the temperature of the baffle plate is low, water drops are generated on the inner side of the baffle plate, the exhaled humid air is prevented from going further upwards, water mist is prevented from being generated on a face screen at the visual field, and a clear visual field is provided for medical staff.
The number of the through holes 5 is 3-5, and the through holes are uniformly distributed on the plate body of the baffle 6. The gas on baffle upper portion circulates to the baffle lower part through the through-hole on the baffle, promotes gaseous from the top down circulation flow, prevents that expired gas from gathering at the baffle front end, and for preventing the drop of water that the inboard production of baffle from flowing down along the baffle, the cotton sliver that absorbs water is used for adsorbing the drop of water, convenient change.
The face screen 1 is connected with an elastic apron 2. The elastic apron provides all-round protection for medical personnel wearing the mask.
The baffle 6 is obliquely and upwards arranged on the panel 1, and the included angle between the baffle 6 and the panel 1 is 100-120 ℃. The baffle that the slope upwards set up can effectively prevent to wear the in-process and cause the problem of collision to the face, sets up the silica gel pad that can prevent at the baffle terminal surface simultaneously that the baffle from extrudeing, colliding the bridge of the nose, plays the cushioning effect.
The drawings and the explanation are only for one embodiment of the present invention, but the specific protection scope of the present invention is not limited to the above explanation, and any simple replacement or change within the technical idea of the present invention and the technical solution according to the present invention should be within the protection scope of the present invention.
