Description

TECHNICAL FIELD

[0001] The utility model relates to a toxic mask technical field, concretely is a kind of toxic gas safety protection device in chemical plant. BACKGROUND

[0002] The main function of the toxic mask is to filter out toxic gases, vapors, and particulate matter from the air, preventing these harmful substances from entering the wearer's respiratory system, thereby reducing the risk of poisoning, suffocation, or other health hazards. The toxic mask is designed with a tight seal to ensure a close fit on the wearer's face, preventing gas from entering from the edges of the mask. At the same time, the built-in filter adsorbs or neutralizes toxic gases, ensuring that the air is purified before entering the wearer's respiratory tract. Common filters include activated carbon filters, chemical filter canisters, and particulate matter filters, which are designed to filter different types of toxic gases or particles. The structure of the toxic mask usually consists of a mask body, a filter, a breathing valve, and an adjustable headband. The filter is a key component that removes harmful substances through physical or chemical methods, while the breathing valve controls the airflow during inhalation and exhalation to prevent external contaminated air from entering.

Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-5The utility model provides a kind of embodiment of chemical plant toxic gas safety protection device, including gas mask body 1 and the annular hollow exhaust disc 4 of fixed ring inside gas mask body 1 one end, annular hollow exhaust disc 4 is installed on the outer wall of the side close to the opening of gas mask body 1, nose cover monomer 2, nose cover monomer 2 and gas mask body 1 between are provided with clean air zone 3, one side inside nose cover monomer 2 is installed with air pipe 7, the end of air pipe 7 extends to the inside installation of annular hollow exhaust disc 4 with annular air pipe 5, annular air pipe 5 is provided with the exhaust hole 501 of being connected with the internal cavity of annular hollow exhaust disc 4 on outer wall, the other end of air pipe 7 is installed with telescopic mouthpiece 8, telescopic mouthpiece 8 is used for user mouth to hold, the one side of the top of gas mask body 1 is installed with the one-way valve 6 for the internal gas one-way discharge of annular hollow exhaust disc 4;

[0020] Exhaled gas enters annular hollow exhaust disc 4 through air pipe 7, annular air pipe 5, and the exhaust hole 501 on the outer wall of annular air pipe 5 evenly distributes exhaled gas to the entire annular hollow exhaust disc 4, and annular hollow exhaust disc 4 is suitable for rapidly discharging a large amount of gas, preventing the accumulation of moisture and carbon dioxide in the mask, while ensuring the freshness of the air in the mask.

[0021] A plurality of through holes 201 are formed in the outer wall of nose cover monomer 2, and the through holes 201 enable the internal cavity of nose cover monomer 2 to be in communication with clean air zone 3.

[0022] The through holes 201 enable clean air zone 3 inside gas mask body 1 to be in communication with the internal cavity of nose cover monomer 2, ensuring that filtered air can pass through the through holes 201 and be inhaled by the user's nose, so that air can only be inhaled in one direction, and toxic gas is prevented from entering the respiratory tract from the outside world.

[0023] A circular notch portion for air circulation is arranged at the center position of annular hollow exhaust disc 4, and air pipe 7 and annular air pipe 5 are both made of a component of rubber material.

[0024] Telescopic mouthpiece 8 includes a corrugated telescopic tube 801 mounted at the bottom end of air pipe 7 and a tapered medical mouthpiece 802 mounted at the bottom end of corrugated telescopic tube 801, the central axis extension line of tapered medical mouthpiece 802 is perpendicular to the central axis extension line of corrugated telescopic tube 801, the user's mouth bites tapered medical mouthpiece 802, at this time, tapered medical mouthpiece 802 can be freely stretched and the angle adjusted through the arrangement of corrugated telescopic tube 801, so as to use the facial features of different users, improve the use flexibility of tapered medical mouthpiece 802, and allow the wearer to quickly guide exhaled gas into subsequent annular hollow exhaust disc 4 and discharge it through one-way valve 6.

[0025] In use, the user first wears the anti-virus mask body 1 to the face position, which seals the wearer's head and ensures that harmful substances cannot penetrate. The nose cover body 2 is designed to seal around the wearer's nose, ensuring that the wearer's breathing passage is tightly connected to the clean air area 3 inside the anti-virus mask body 1. When the wearer wears the anti-virus mask body 1, the nose cover body is in close contact with the nose, forming a complete seal. The filtered air in the anti-virus mask body 1 is inhaled through the clean air area 3 and the nose cover body 2, preventing toxic gases from entering the respiratory tract from the outside. The user's mouth bites the air inlet end of the telescopic mouthpiece 8, and the nose inhales. The exhaled gas enters the telescopic mouthpiece 8 through the mouth, i.e. the exhaled gas enters the annular hollow exhaust disc 4 through the exhaust pipe 7 and the annular air pipe 5, which are isolated from the internal chamber of the anti-virus mask body 1, and then is discharged outside the anti-virus mask body 1 through the annular hollow exhaust disc 4 and the one-way valve 6, avoiding the mixing of exhaled gas and inhaled filtered air, thereby ensuring air quality. The one-way valve 6 ensures that the exhaled gas can only flow in one direction and cannot flow back into the mask. When the wearer exhales, the one-way valve 6 opens to allow the exhaled gas to flow smoothly out of the mask. Conversely, when the wearer inhales, the one-way valve 6 closes to prevent harmful gases from entering the mask, thereby ensuring that the anti-virus mask body 1 can effectively protect the wearer's health in a high-risk environment, avoid the intrusion of toxic gases, and ensure the comfort of the wearer during long-term use.
