A type of isolation protective headgear

Abstract

This application provides an isolation protective headgear, including a headgear and a protective end piece integrally formed with the headgear. The headgear comprises a double-layer headgear formed by an inner protective layer and an outer protective layer, with a support frame disposed between the inner and outer protective layers, the support frame being disposed on the inner protective layer. A support airbag is disposed through the inner wall of the outer protective layer. This utility model, by adding a support airbag and a support frame that works in conjunction with the support airbag, effectively prevents the support frame from collapsing and conforming to the face due to sweat or deformation caused by movement, enhancing airflow space and improving comfort. Furthermore, the support frame, made of lightweight materials and hollow in design, significantly reduces weight, effectively preventing headaches or skin pressure injuries caused by a heavy support frame.

Description

Technical Field

[0001] This utility model belongs to the field of isolation and protection technology, and specifically relates to an isolation and protection headgear. Background Technology

[0002] Isolation protective headgear is mainly used in medical and other environments. Through its sealed structure, it covers the head, neck and shoulders to block viruses or bacteria carried by droplets, blood, aerosols, etc., significantly reducing the risk of infection for medical staff.

[0003] The protective headgear is mainly composed of SMS composite non-woven fabric, elastic straps, and an adjustment system. However, after a period of use, the protective headgear made of SMS composite non-woven fabric will generate a lot of heat inside the headgear due to the user's breathing. This will keep the skin in a high-humidity state for a long time, disrupting the acid-base balance and making it easy to induce acne, folliculitis, or fungal infections.

[0004] Therefore, how to solve the defects in the above-mentioned technical solutions has become one of the urgent problems to be solved in the field of isolation and protection technology. Utility Model Content

[0005] In view of the problems existing in the background art, the present invention provides an isolation and protective headgear, comprising:

[0006] Headgear

[0054] This invention is mainly used for the extraction of spice raw materials in the research of seasonings.

[0055] like Figure 1-5 As shown, this embodiment provides an isolation and protective headgear 100, including a headgear 20 and a protective end 30 integrally formed with the headgear 20.

[0056] The headgear 20 includes a double-layer headgear 20 formed by combining an inner protective layer 701 and an outer protective layer 702, and a support frame 40 is provided between the inner protective layer 701 and the outer protective layer 702. The support frame 40 is attached to the inner protective layer 701 by adhesive or sewing.

[0057] Furthermore, the support frame 40 is made of lightweight material, and the support frame 40 is provided with a detachable protective mask 501 and a neck protection end 502 integrally formed with the protective mask 501;

[0058] Furthermore, the protective mask 501 near the bridge of the nose has an arc-shaped end face 503 that fits against the cheek, and a nose clip 504 is provided between the two arc-shaped end faces, with the nose clip having a length of 8mm or more. By adding the nose clip 504, pressing the nose clip to fit the curve of the bridge of the nose eliminates the gap between the mask and the nose, preventing unfiltered air such as droplets and viruses from seeping in from the bridge of the nose.

[0059] Furthermore, the support frame 40 is provided with at least one set of reinforcing ends 401, and the reinforcing ends are provided along the arc surface of the support frame 40. The reinforcing ends 401 are provided with snap-fit ​​grooves 402, and the snap-fit ​​grooves are provided with two sets of opposite and concave first end faces 4021. The second end face 4022 connected to the first end face 4021 is inclined, and the angle between the second end face and the transverse end face is 135°.

[0060] Furthermore, the inner wall of the outer protective layer 702 is provided with a support airbag 703 by adhesive or sewing, and the support airbag 703 is provided with two sets of outwardly protruding snap fasteners that extend into the snap fastener grooves and are in close contact with the first end face 4021 and the second end face 4022 respectively.

[0061] In this example, those skilled in the art should understand that the 135° inclined second end face in the snap-fit ​​groove forms a wedge fit with the protruding part of the support airbag, generating a radial component force (horizontal component force = vertical load × tan45°) when under load, causing the protruding part of the airbag to press against the first end face 4021, thus achieving mechanical self-locking.

[0062] Furthermore, a Velcro closure 704 integrally formed therewith is provided on the inner wall at the neck position of the outer protective layer 702.

[0063] An air supply pipe 60 is provided on the neck protection end 502. The air supply pipe can be fixedly connected by adhesive or other means. One end of the air supply pipe 60 passes through the air supply hole 10 provided on the protection end 30, and a control valve is provided on the air supply pipe 60 passing through the air supply hole 10.

[0064] In this embodiment, the gas supply pipe 60 can be connected to an external gas supply device, and gas can be supplied into the gas supply pipe through the external gas supply device.

[0065] Furthermore, the other end of the air supply pipe 60 is connected to the air inlet of the supporting airbag.

[0066] In this embodiment, those skilled in the art should understand that after the staff puts on the protective isolation headgear, the external air supply equipment and the support airbag are connected through the air supply pipe. The control valve on the air supply pipe is opened, and air is inflated into the support airbag through the air supply pipe. The support airbag expands continuously until the snap-fit ​​part on the support airbag snaps into the snap-fit ​​groove, forming a plug-in module with the snap-fit ​​groove, thus completing the connection between the support airbag and the support frame.

[0067] This invention adds a support airbag and a support frame that works in conjunction with the support airbag. The support frame can effectively prevent the support from collapsing and fitting the face due to sweat or deformation caused by movement, enhance airflow space, and improve comfort. At the same time, in conjunction with the support airbag, and because the support frame is made of lightweight materials and has a hollow interior, the weight is greatly reduced, which can effectively avoid headaches or skin pressure injuries caused by the weight of the support frame.

[0068] Furthermore, the Velcro 704 is used to attach and connect the cooling care storage bag 801, and the outer wall of the cooling care storage bag is provided with a wrapping layer that works in conjunction with the Velcro 704 for attachment and connection.

[0069] The cooling care storage bag 801 has a replaceable gel layer 803 inside, and the replaceable gel layer 803 preferably uses a thermally conductive gel block. The outer wall of the replaceable gel layer 803 is provided with multiple sets of outwardly protruding semi-circular friction protrusions 802. By adding friction protrusions 802 to increase the contact area with the cooling care storage bag, the replaceable gel layer can be effectively prevented from falling out of the cooling care storage bag.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not restrictive. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered by the claims of this utility model.
