Description

Chasing type micro dust-filter

The present invention relates to the micro dust filter that a kind of articles for labour protection are spiral plate type.Be applicable to that the various people that work wear in the ash of being everlasting (powder) dirt environment.

A lot of people are operated in throughout the year and are harmful in the big environment of healthy ash (powder) dirt.Resemble the workman of exploitation worker, heading driver and cement plant, coke-oven plant, lime factory, cotton mill, brickkiln and work stone factory on the ore deposit especially; take effective safeguard procedures; to the protection health, reduce because the interior excessive caused various diseases of ash (powder) dirt of suction body is very important.But for a long time, this problem never is well solved.Its main cause is, there is not a kind of volume both little, weight is light again, carry and wear conveniently, neither influence is breathed and is not hindered the miniature protector of operate as normal to replace existing appliances for labor protection again, as: mouth mask, dustproof muzzle cover and so on, it is unimpeded both to have influenced breathing, is an impediment to the protective equipment of work again.The present invention is exactly in order to address this problem, and has designed this kind chasing type micro dust-filter.Its basic structure and operation principle by: dirt catcher is made up of two parts: the nasal obstruction (connecing the nostril semi-cylindrical hill) part and dust filtration device, both can be connected and are one, the plug of nasal obstruction part can directly insert in the nostril, the basic configuration of its plug identical with people nostril face shaping feature (or close).(connecing the nostril semi-cylindrical hill) directly withstands on the outside, nostril.The positive view plane of nasal obstruction base is provided with two micro dust devices, and its essential characteristic is: drum or other shape, and vertically be equipped with several air admission holes at a certain position on its surface.Be provided with the filter dirt sheet of a valve snail rotating plate shape in the dust filtration device, and be provided with on its surface and gather the venetian blind type dust-stopping plate arranged and to scribble one deck dust adhering agent, the center of the filter dirt sheet that spiral is tabular joins with nasal obstruction plug central opening of the seal.Like this, when the air that has ash (powder) is in dust filtration device surface perforate enters its jar, air-flow can not directly enter people's nostril but move as ring wall along the spirality cavity body, in the process of motion, because action of centrifugal force makes the dust particle in the motion break away from its original track, changes into along the tangential direction of circumference and moving, like this, airborne dust particle just constantly with its cavity in the spirotheca surface bump.In striking process, because the cavity inner wall surrounded surface is equipped with the densely covered louvre type dust-stopping plate of arranging and scribbles one deck dust adhering agent on its surface, with in respiratory, the steam that human body is breathed out condenses in its surperficial condensed water after running into the spiral plate cooling, and under the impact of Inertia in Airflow pressure, grit has just constantly been sticked on the inner wall surface of revolving the body cavity, like this, when the air that has dust advances to when revolving the body centre, the dust particle that is had in the air all has been adhered on the spirotheca louvre type dust-stopping plate surface of revolving the body cavity basically, so it can play the effect of filter dirt effectively.

The present invention is owing to adopted the spiral plate type structure, so reduced volume, owing to adopted nasal obstruction plug (or connecing the nostril semi-cylindrical hill), and hollow base, and adopt lightweight material, so alleviated its weight, owing to adopted direct air inlet dust-filtering system, air enters the amount of flow in nostril in unit interval so increased, and can prevent that airborne dust from directly entering the nostril thereby reached, and breathe unimpeded purpose.

Specific embodiments of the present invention is as follows:

A kind of scheme is: nasal obstruction plug (or connecing the nostril semi-cylindrical hill) and base single injection-molded, and preferably make hollow.Like this, be easy to alleviate himself weight and reach certain appearance feature, cost is low.The face shaping of nasal obstruction (or connecing the nostril semi-cylindrical hill) and base is preferably made with people's anterior nares external appearance characteristic and is matched (or close) in addition, like this, when the user wears, can avoid facial preceding foreign body sensation.Wear comfortable effect thereby reach.The plug ends of having a stuffy nose in addition shape is preferably made ellipse or is bordering on people nostril shape, and the end should be a bit larger tham root, also can open a criss-cross groove in its end, makes its end that certain elasticated be arranged, and is unlikely owing to self the weight nostril that comes off.Base exterior edge and thickness thereof are difficult for excessive, blocked up.Pedestal and plug are preferably made hollow body, another kind of scheme is: except that airway, nasal obstruction plug (or connecing the nostril semi-cylindrical hill) and disjunctor base all adopt injection moulding, make solid, the advantage of this kind scheme is, easily one-shot forming, technology is simple, saving of work and time, nasal obstruction (connecing the nostril semi-cylindrical hill) and base are linked as a solid integral body, and intensity is big, not fragile, shortcoming is the weight that has strengthened base, has used raw material more, and the profile of filter dirt jar is preferably made drum (post) shape, be convenient to match with its base plane, and preferably injection moulding one-shot forming, the louvre type dust-stopping plate in the filter dirt jar is preferably with filter dirt jar disjunctor single injection-molded.The size of filter dirt tank surface perforate, what are breathed the maximum of the air draught amount in the required unit interval and decide because of the reference normal human.And be preferably vertical arrangement of tank body master apparent direction.Like this, can increase and have the flowing time of ash (powder) dirt air in tank body.

Also can design a kind of micro dust filter that directly withstands on the nostril according to basic design of the present invention in addition, the primary structure of this dirt catcher, operation principle is all with above-mentioned said the same, different is to change the nasal obstruction plug into the center porose hollow nostril semi-cylindrical hill that connects, during use not trunk plug plug insert in the nostril like that, but directly two semi-cylindrical hills are withstood on the nostril, so just more reduced because the nasal obstruction plug inserts caused sense of discomfort in the nostril.After wearing, the user feels more comfortable.As accompanying drawing, shown in Figure 2.
