Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of breathing circuit filter.
Background technology
Along with entering increasing of airborne pollutant, air quality worse and worse, PM2.5 day by day raises as air pollution index, namely particle diameter increases less than the particle of 2 μ m in the air.Pollutant can be deposited on the upper respiratory tract after entering the human lung, and the following contamination particle of 2 μ m also can be deep in bronchiole and the alveolar, can cause diseases such as chronic bronchitis, bronchial astehma, pulmonary emphysema and lung cancer.Therefore, filter more and more for the air that sucks lung and be necessary.
In the prior art, breathing circuit filter totally can be divided into two kinds of built-in and externals.The external breathing circuit filter generally includes breathing mask and mouth mask.The mouth mask masked area is big, human body sensory is sealed vexed, comfort is poor, especially for the people of wearing spectacles and mention its inconvenience: when wearing mouth mask, the gas that people itself breathes out is most of discharges by the mouth mask periphery, steam in the breath easily on glasses condensation haze, influence people's eyesight, even the bleed accident.Breathing mask is to utilize materials such as active carbon that air is carried out adsorption filtration; its filter effect carefully; but volume is bigger; price is higher; and using whole head wraps up; human sense of comfort is not high, and this protective device is suitable for professional person or the unusual abominable situation of external environment condition, is unsuitable for using in the daily life.Built-in breathing circuit filter is with the filter microminiaturization, inserts nasal cavity, but this built-in breathing circuit filter can make the people produce sense of discomfort, and the easy contaminated filter device of nasal secretion.
The utility model content
Main purpose of the present utility model provides a kind of filtered air simple in structure, effective, wears the breathing circuit filter of Energy and comfort.
To achieve these goals, the technical scheme that adopts is: a kind of breathing circuit filter, comprise breathing equipment and filter, described breathing equipment comprises respiratory siphon, the respiratory siphon sidewall arrange two groups corresponding with the nostril and run through the through hole of respiratory siphon, corresponding every group of through hole place arranges the filter with this group through hole sealing in the respiratory siphon, be positioned at the check valve diaphragm that filter waste gas outlet end face can be covered is set on the filter waste gas outlet end face of respiratory siphon tube wall one side, the part of described check valve diaphragm and this filter waste gas outlet end face is affixed; The respiratory siphon end is communicated with filter.
That is to say that the setting of respiratory siphon sidewall runs through the through hole of respiratory siphon, through hole forms two groups of corresponding holes at the respiratory siphon sidewall, and each organizes Kong Yuyi nostril correspondence, in one group of through hole, what be positioned at the nostril end is the cleaned air import, and another hole is waste gas outlet; The check valve film sheet is set outside waste gas outlet, and the check valve diaphragm can be common plastic film, and the check valve diaphragm covers two holes outside respiratory siphon; Corresponding every group of through hole place arranges filter in the respiratory siphon, and filter is common cotton or nonwoven cloth material, and filter seals every group of through hole, covers on the check valve diaphragm on the through hole to fixedly connected with the part of filter waste gas outlet end face; The respiratory siphon two ends are communicated with filter.
Operation principle of the present utility model is: when air-breathing, the respiratory siphon internal pressure is less than atmospheric pressure, and the check valve diaphragm is closed, and air installs after filtration to filter and enters respiratory siphon, enters the nostril through filter, cleaned air import again; During expiration, the respiratory siphon internal pressure is greater than atmospheric pressure, and the check valve diaphragm is opened, and breath enters atmosphere from the respiratory siphon waste gas outlet through the check valve diaphragm.
Owing to be provided with the check valve diaphragm, when air-breathing, close, allow the people can suck the air that installs after filtration after filtering, and when exhaling, open, allow the people waste gas of breathing out easily can be entered atmosphere, strengthened people's comfort greatly; Corresponding every group of through hole place arranges filter in respiratory siphon, is in order to prevent that the check valve diaphragm from opening when changing to closure, and the air of pollution is directly sucked; Breathing equipment separates with filter, and filter can be worn at other place on one's body, and as on the belt or not on pocket, it is very convenient to make that whole breathing circuit filter carries.
