Abstract
The utility model provides a filter element for a mask. The filter element comprises four layers of filter screens, wherein the first layer is a non-woven fabrics filter screen; the second layer is a gauze filter screen; the third layer is a teflon film filter screen; the fourth layer is another non-woven fabrics filter screen; the four filter screens are sewed together through threads. The filter element provided by the utility model is simple in structure and reasonable in design, and is excellent in filtration effect.
Description
Technical field
The utility model relates to a kind of suction-self filtering type against particle respirator, is specifically related to a kind of mouth mask filter element.
Background technology
Fine particle claims again particulate, fine grained, refers to that particle diameter in atmosphere is less than the particle (aerosol) of 2.5 μ m.Although fine particle is content component seldom in earth atmosphere composition, but compare with thicker Atmospheric particulates, fine particle particle diameter is little, be rich in a large amount of poisonous and harmful substances and the time of staying in atmosphere is long, fed distance is far away, thus larger on the impact of health and atmosphere quality.There is research surface, the particle of 10 μ m diameters is deposited on the upper respiratory tract conventionally, particle below 2.5 μ m can be deep into bronchiole and alveolar, and fine particle enters human body after alveolar, directly affect the ventilatory function of lung, make body easily be in anaerobic condition, once and this fine particle enter alveolar, be adsorbed on alveolar and be difficult to drop, this absorption is irreversible.Therefore, for fine particle, the respiratory system protection of human body is had important practical significance, and current used cotton yarn mouth mask can not play real filtration to fine particle.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of anti-dust respirator filter element filtering for fine particle.
To achieve these goals, the utility model is realized by the following technical solutions: a kind of mouth mask filter element, it comprises: described filter element comprises 4 layers of screen pack, ground floor be nonwoven layer screen pack, the second layer be gauze layer screen pack, the 3rd layer for polytetrafluoroethylene film layer screen pack, the 4th layer be nonwoven layer screen pack.Between four layers of screen pack, pass through fine rule close joint together.
On described filter element, be provided with an alarm set for detection of described filter element usage degree, by shifting to an earlier date setup and use threshold value on described alarm set, when described filter element reaches use threshold value, described alarm set is made prompting by turn colors to user, and described alarm set is arranged on the marginal portion of described filter element.
The beneficial effects of the utility model: the utility model is simple in structure, reasonable in design, can reach good filtration.
Accompanying drawing explanation
Fig. 1 is cross-section structure enlarged diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further explained, as shown in Figure 1, a kind of mouth mask filter element, it comprises 4 layers of screen pack, ground floor be nonwoven layer screen pack 1, the second layer be gauze layer screen pack 2, the 3rd layer for polytetrafluoroethylene film layer screen pack 3, the 4th layer be nonwoven layer screen pack 4.Between four layers of screen pack, pass through fine rule close joint together.
On filter element, be provided with an alarm set 5 for detection of described filter element usage degree, alarm set 5 is arranged on the marginal portion of institute's filter element, by shifting to an earlier date setup and use threshold value on alarm set 5, when filter element reaches use threshold value, alarm set 5 is made prompting by turn colors to user.User is according to the prompting changing filter element of alarm set 5.
The beneficial effects of the utility model: the utility model is simple in structure, reasonable in design, can reach good filtration.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
