Description

Mask integrated protective clothing with air inlet and exhaust design

Technical Field

The invention belongs to protective clothing suitable for epidemic prevention, and particularly relates to mask integrated protective clothing with an air inlet and exhaust design.

Background

The positive pressure protective clothing is high in protection efficiency and comfortable in body feeling of a user due to the internal positive pressure, and is a new trend of epidemic prevention products. The known positive pressure protective clothing technology is designed for a non-skull-top exhaust passage, and a head air chamber and a body air chamber are directly communicated in a penetrating way, such as:

the positive pressure protective clothing (CN 111135493A) has the functions of gas defense, purification, ventilation, exhaust and heat dissipation, the cap body and the neck of the protective clothing are in loose design, the cap body is isolated from the head and the neck by gas after inflation, and the air chamber at the head of the protective clothing is directly communicated with the air chamber at the body; although the protective clothing is provided with the air outlets at the mouth and nose, the air outlets at the ears, the air outlets at the inner sides of the elbows, the air outlets of the chest, the back and the popliteal fossa, all the air outlets are provided with filter screens for isolating viruses when air flows reversely, and the air flow is small. The technology lacks a directional internal circulation air passage design, and the problems of unsmooth air flow internal circulation and unsmooth air exhaust cannot be solved well, such as body hot flashes and body-exhausted foul smell ascending.

A protective clothing with air-flow internal circulation and its air-flow internal circulation method (CN111567918A), the cap and neck of the protective clothing are designed loosely, the air chamber of the head and the air chamber of the body are directly communicated; in the technology, two pressing leg tubes 321, two pressing sleeve tubes 322 and a pressing header tube 323 are communicated with each other to form a pressing air tube 320; the two aspiration leg tubes 421, two aspiration sleeve tubes 422, aspiration main tube 423 and aspiration head sleeve 424 are connected to form the aspiration trachea 420. The technology adopts a plurality of groups of built-in air pipes for pressing in and sucking out, solves the problem of smooth internal circulation of air flow, but 11 air pipes are difficult to process, high in price and not suitable for disposable use in protective clothing, and wearers squat, stand, sit, lie, walk and lift the arms to press the air pipes, so that the actions are not changed and the wearing is uncomfortable.

Disclosure of Invention

In order to solve the problems, the invention provides a mask integrated protective garment with an air inlet and exhaust design, which comprises a skull top air inlet pipe, a skull top exhaust passage, a crotch exhaust pipe, a sealing joint, an inner cap suture line, an outer cap suture line, a mask air chamber and a body air chamber.

The whole protective clothing air chamber is separated into a mask air chamber and a body air chamber by the inner and outer cap sewing lines, and the mask air chamber is communicated with the body air chamber through the skull top exhaust passage.

The cranial air inlet pipe is hermetically connected with an external air supply device, and airflow enters the mask air chamber from the cranial air inlet pipe and enters the body air chamber through the cranial air exhaust passage.

The air inlet pipe head of the crotch exhaust pipe is positioned at the front crotch part in the protective clothing, and the air outlet pipe head at the other end penetrates out of the protective clothing through the sealing joint and is connected with the external air suction device in a sealing manner, so that the damp and hot air in the body air chamber is discharged, the problem of sultry and humidity in the protective clothing is solved, and the problem that the turbid air discharged by the human body enters the mask air chamber in an upward manner is solved.

Furthermore, the outer cap and the inner cap on the two sides of the cranial crown air inlet pipe are sewn at the position of the cranial crown to form an inner cap sewing line and an outer cap sewing line, the front ends of the outer cap and the inner cap are sewn into a whole, and the whole protective clothing air chamber is separated into a mask air chamber and a body air chamber.

Furthermore, the outer cap and the inner cap on the two sides of the skull top air inlet pipe are sewed at the back of the neck, the skull top air inlet pipe is limited and fixed, the outer cap and the back end of the inner cap are sewed into a whole, and an air cavity between the outer cap and the inner cap forms a skull top exhaust passage.

Furthermore, the outer cap and the inner cap above the 1 intersection point are not sewed, an opening between the outer cap and the inner cap is not only a through hole for the skull top air inlet pipe to enter the mask air chamber, but also an air outlet for the mask air chamber to be communicated with the skull top air outlet passage, and the skull top air outlet passage is communicated with the body air chamber.

The invention has the beneficial effects that: the invention can discharge the air in the mask to the back through the skull top exhaust passage, thereby improving the problem that the back of a wearer is sultry and moist, and improving the problem that the carbon dioxide instantaneously exhaled by the wearer is increased in concentration and cannot be discharged in time. The exhaust pipe on the crotch can exhaust damp and hot gas in the protective clothing, so that the problem that the lower limbs of epidemic prevention personnel wearing the protective clothing are sultry and damp is solved, and the problem that foul smell exhausted from the body goes upwards is solved.
