Description

Protective mask for preventing water mist

Technical Field

The utility model relates to the technical field of medical supplies, concretely relates to protective face mask of waterproof fog.

Background

When a medical institution checks and treats, the phenomena of body fluid, blood splash or splash are easy to occur, and if the medical institution uses the virus during the period of virus outbreak, many medical workers are infected due to poor protection. In view of this, CN111165959A in the prior art discloses a protective mask for preventing water mist, which comprises a cap body, a soft pad sewn in the cap body, an arc-shaped mask arranged at the front part of the cap body, binding bands fastened at both ends of the cap body by resin, and a high-elastic sponge strip and a rubber band with specifications matched with the binding bands. To accommodate more people, the downward extension of the curved mask is too long, and if the head is lowered downward during use, the bottom of the curved mask will rest against the chest to prevent the person from continuing to lower his head, and the field of vision will be affected.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art's not enough, provide a downward view field of vision can not receive the isolation face guard that has antifog function that influences.

The utility model relates to a protective mask for preventing water mist, which comprises a cap body, wherein the shape of the cap body is an arc shape which is jointed with the forehead, the front part of the cap body is provided with an arc-shaped mask, and two ends of the cap body are connected with elastic bandages; the middle part of the cap body is a sponge strip which is shaped, the front and the back of the arc-shaped face mask are both stuck with antifogging PET films, the arc-shaped face mask is connected with the cap body in a sliding mode along the vertical direction, and the bottom of the arc-shaped face mask is detachably connected with a flexible transparent blocking curtain.

The utility model discloses a theory of operation and beneficial effect, the protective face guard of waterproof fog of this application improves on prior art's basis, specifically all pastes at the front and the back of arc face guard and has antifog PET film. At present, when the surface of an arc-shaped mask is subjected to antifogging treatment, a high-molecular PET lens is generally adopted, namely, an antifogging agent is directly added into a PET raw material, and the mixture is subjected to extrusion molding after blending to produce an antifogging membrane; the other is that directly spraying antifogging agent on the arc face guard that has already processed, first mode is owing to increased a raw materials, need change equipment and corresponding technological parameter when mixing multiple raw materials, so the cost is higher, and the form that adopts direct spraying again can cause the influence to antifogging effect because of the spraying inequality, and based on this, this application is pasted antifogging PET film on the isolation face guard that does not have antifogging function, adopt the mode of pasting corresponding after independent processing, can not cause the influence to the extrusion moulding technology of former arc face guard, the face guard of abandoning in addition also can be peeled off antifogging PET film from the top, cyclic utilization.

In the use, because arc face guard and cap body are along vertical direction sliding connection, so can upwards perhaps slide the arc face guard as required, avoid arc face guard to support on the chest in the time of the low head, the downward field of vision of looking down causes the influence to the low head, and in order to avoid when upwards sliding the arc face guard, the neck of lower part is exposed out and is contacted with external infection source, set up the flexible curtain that keeps off of detachable in the bottom of respirator, do not influence the field of vision again when sealing the neck, flexible curtain that keeps off is made by transparent, waterproof flexible material.

The utility model discloses an isolation face guard with antifog function not only possesses antifog function, and recycle can also be taken off to this antifog PET film simultaneously, and the user can adjust arc face guard downwardly extending's length as required in addition, avoids causing the influence to the field of vision when guaranteeing to keep apart the effect.

Further, the end part of the arc-shaped face mask connected with the cap body is provided with a sliding block, and the cap body is internally provided with a sliding groove connected with the sliding block in a sliding manner. Through setting up the slider, make the slider slide in the spout, play the purpose of adjustment arc face guard extension degree downwards.

Furthermore, a limiting component for limiting the sliding block to slide in the sliding groove is arranged on the sliding block and/or the sliding groove. Through setting up spacing subassembly, carry on spacingly to the slider, make the arc face guard can keep in corresponding position department on the cap body, the contact surface of slider and spout is the curved surface in this application, and the main purpose is to increase gliding frictional force, can carry on spacingly to the slider.

Furthermore, the transparent curtain is connected with the bottom of the arc-shaped mask through a snap fastener. The snap fastener is arranged on the outward side of the arc-shaped mask, and the transparent curtain completely covers the bottom end of the arc-shaped mask.

Furthermore, a sweat absorbing belt is arranged at the position where the cap body is contacted with the human body, and a plurality of vent holes are formed in the sweat absorbing belt. The part of the cap body contacted with the human body can sweat after being worn for a long time, and in order to enhance the heat dissipation effect, the sweat absorbing belt is arranged firstly and a plurality of vent holes are arranged on the sweat absorbing belt.

Further, an air inlet hole communicated with the air vent is formed in the cap body, a small fan is arranged in the cap body, and the small fan is electrically connected with a power supply and a switch. A small fan is arranged in the cap body, and the small fan is started to enhance the circulation of air.

Furthermore, a high-elasticity sponge strip and a rubber band which are matched with the elastic bandage in specification are additionally arranged in the elastic bandage. The arrangement of the high-elastic sponge strip and the rubber band can reduce the pressing force of the elastic bandage on the head while ensuring the fixation.

Furthermore, the elastic bandage is provided with an adjusting buckle for adjusting the length. The length of the elastic bandage can be conveniently adjusted according to the head circumference of a user.
