ИзЪбретение относитс к устройствам дл спасени жизни и может быть использовано как средство охраны труда в сельском хоз йстве при работе в запьшенной атмосфере при наличии в воздухе вредных ветесте.Seizure refers to life-saving devices and can be used as a means of occupational safety in agriculture when working in a clean atmosphere when there is harmful vetest in the air.
Известны прибо1 а дл зашиты органов дыхани , содержсшшб маску с обтюратором , устройства дл подведени .и распределени воздуха и.элементы креплени 1.Known are devices for protecting the respiratory organs, containing a mask with a obturator, devices for air inlet and air distribution, and fastening elements 1.
Такие приборы недостаточно удобны в° эксплуатации.Such devices are not convenient enough in ° operation.
Известна также защитна маска, родержаща корпус с обтифатором, ограничивающим подмасочное пространство , верхн Чисть которого сообщена через воздухоподвод цйе кана .лы с источником, а нижн вблизи подбородочной стенки - с выпускным отверстием 2j.A protective mask is also known, which holds the body with an obturator, limiting the submask space, the upper part of which communicates through the air duct of the canal with the source, and the lower one near the submental wall - with the outlet port 2j.
Основншл недостатком такой маски вл етс непрерывна подача воздуха . Это вызывает пульсацию давлени воздуха в подмасочном пространстве, затрудн ет лдахание, неблагопри тно вли ет на 1дазиологические функции организма. The main disadvantage of this mask is the continuous flow of air. This causes the air pressure to pulsate in the masked area, makes it difficult to read, and adversely affects the body's environmental functions.
Целью изобретений вл етс уменьшение нагрузки на органы дыхани иThe aim of the inventions is to reduce the load on the respiratory system and
повышение эффективности их зациты путем/интенсификации сброса углекислоты при выдохе.increasing the efficiency of their reactions by means of / intensifying the discharge of carbon dioxide during expiration.
Дл этого маска снабжена струйным элементом, имеющим питающий канал , по два перепускных и управл ющих канала и установленные в последних регулируемые дроссели, при этом один из перепускных каналов служит дл For this, the mask is equipped with an inkjet element having a supply channel, two bypass and control channels, and adjustable throttles installed in the latter, one of the bypass channels serving
o подсоединени воэдухоподвод щих каналов и сообщен управл ющим каналом на участке подключени .к питающему каналу с подмасочным пространством, а другой - дл эжекции газа, сбрасы5 ваемого через выходное отверстие, и сообщен управл ющим каналом в средней части со своим участком в месте подключени к питгиощему каналу.o connecting the air ducting channels and communicating with the control channel at the connection site to the supply channel with submask space, and the other for ejecting gas discharged through the outlet opening, and communicating with the control channel in the middle part with its section at the connection point to the power supply channel.
При этом один из управл ющих кана0 лов сообщен с предлицевым участком подмасочного пространства напротив рта, а перепускной канал, служащий дл эжекции сбрасываемого газа, проложен в подбородочной стенке корпуса.At the same time, one of the control channels is connected to the pre-face area of the masked area opposite the mouth, and the bypass channel, which serves to eject the discharged gas, is laid in the submental wall of the body.
