Description

Disposable dust protective mask

Technical field

The utility model relates to a kind of mouth mask, and particularly a kind of human body that prevents sucks the disposable dust protective mask of dust and harmful substance.

Background technology

In general, working environments such as paper mill, textile mills, stone pit can produce many dust, and various chemical plant, welding, refinement, Metal Processing Factory such as gold-plated also can produce a large amount of toxic gases.If the constructor sucks harmful substances such as these dust for a long time, human organs such as lung will cause fatefulue disease, even also can become the cause of disease of asthma, thus need wear mouth mask in addition, thus in these hostile environments, protect the health of self.

In order to satisfy the demand, adapt to various abominable working environments, produce diversified dustproof, the poison gas protection equipment that has the mouth mask and the poison gas protection equipment of dustproof, gas defence material and filtration equipment for clarifying and be provided with the stronger dust-proof material of dust absorption function.Generally being bottom at the gas defence material---nonwoven upper berth one deck scatters the gasket material of active carbon, and carry out knitting connection in gasket material upper berth layer of non-woven fabric, make dustproof, poison gas protection equipment consistent with each other, the product of dress filter paper in also having in addition, but the price of these products is comparatively expensive, and also needs to change the gas defence material one time every 3,4 days, and its filter efficacy also falls flat, so in the working environment of paying attention to health, often use disposable dust protective mask.

Because it is disposable use, so the product quality of existing disposable dust protective mask is extremely coarse, can't reach the Expected Results of the harmful substances such as dust in the complete filtered air.

Therefore, produced multiple more efficiently product recently.That is, for several times folding filter paper forms the gauffer shape, and the both sides of filter paper are carried out heat and merged with being linked with, and forms light end, but then at the wire of the top of filter paper installation free bend, makes disposable dust protective mask.

But this product makes its face of being close to the outstanding user of face mask, and launches the gauffer part of filter paper by the wire of free bend, makes its nose of being close to the user and lower jaw position, to increase dustproof effect.But launch to be close to user's face along above-below direction owing to the filter paper of above-mentioned common anti-dust respirator, so at filter paper when above-below direction launches, form the slit during middle bent of the last one deck in filter paper two ends, can't complete closed user's nose around.

Because dust can be inhaled into human body by this slit,, and user's health constituted serious threat so its dustproof effect is not ideal enough.

In addition, being used in being linked with on this anti-dust respirator is to adjust its length according to user's facial shape, but otherwise designed is not adjusted the instrument of length, but be that length is adjusted according to instructions for use when being linked with in two ends, so when using disposable dust protective mask in advance, need suitably to adjust be linked with length, bring very big inconvenience to the user.

And, because this anti-dust respirator must install wire, so will cause serious environmental to pollute during discarded disposable dust protective mask.Especially when nose that covers the user by anti-dust respirator fully and lower jaw position since its distance is wide up and down, anti-dust respirator is hung over ear can make narrow that the amplitude that is linked with becomes, cause the filter paper both-side ends crooked and form the slit.

Therefore, No. 274873 product of the utility model patent that the applicant of this patent provides is the same, only form crooked gauffer shape in the filter paper top and the bottom, crooked filter paper both-side ends has been used lighter filter paper, and be linked with its terminus inner being provided with, make and be linked with slides within endways, carrying out high-frequency heat with filter paper then merges, thereby when crooked up and down gauffer partly launches, make it more to be close to user's nose and lower jaw position, and can not make the both-side ends bending of filter paper, make it be attached to user's cheeks fully.In addition, inner endways being linked with and can arbitrarily changing length according to user's needs of slidably reciprocating increased dustproof effect greatly, is a kind of disposable dust protective mask very easy to use.

But to the outstanding user of face contour, above-mentioned disposable dust protective mask can't bring the complete aesthetic effect at nose and lower jaw position, so probably therefore suck a large amount of dust and dust, can't reach complete dustproof effect.

Summary of the invention

The purpose of this utility model provides and a kind ofly can overcome effectively that the problems referred to above take place, formed the consistent projection of nose and lower jaw position respectively with the user in the top and the bottom of mouth mask, and with the built-in form that is linked with this mouth mask both-side ends is carried out heat and merge, it is poor to form end respectively at each folded part of filter paper and end, so that easier cutting filter paper and carry out ultrasonic and merge, rely on the projection that is suitable for nose and lower jaw position simultaneously, do not fold mouth mask or exert pressure by force and also can make its face of more being close to the user, the disposable dust protective mask that dustproof effect is very outstanding.

The purpose of this utility model is achieved in that it comprises being linked with that the filter paper, the two ends that form the gauffer part are provided with, it is characterized in that: the filter paper in the gauffer part forms projection in two ends up and down, the projection of lower end should be bigger and wide than the projection of upper end, make its nose of being close to the user respectively and lower jaw position, and divide the formation end poor in the two ends up and down and the terminal cross-section of gauffer part.

The disposable dust protective mask that the utility model provides is provided with two projections up and down, be convenient to the cutting filter paper more, and the easier ultrasonic that carries out merges, rely on the projection that is suitable for nose and lower jaw position simultaneously, folding mouth mask or exert pressure by force and also can make its face of more being close to the user has very outstanding dustproof effect.

The specific embodiment

As shown in the figure, the utility model disposable dust protective mask comprise form that gauffer part 1,1 ' filter paper, two ends be provided be linked with 3,3 ', respectively have gauffer part 1,1 ' filter paper forms projection 5,5 ' in two ends about in the of 2, the projection 5 ' of lower end should be bigger and wide than the projection 5 of upper end, make its nose of being close to the user respectively and lower jaw position, and divide in the cross-section of gauffer part 1,1 ' two ends up and down and terminal 4,4 ' and to form end and differ from 6,6 ', so that carry out cutting and high frequency heat merges operation.

Disposable dust protective mask in the past forms positive square shape with the folding several of the side of inward at both ends up and down of tetragonal pad filter paper 2, and the inside, two ends of its filter paper 2 is provided with respectively and is linked with 3,3 ', and relies on the end portion 4,4 ' of establishing in addition to carry out the heat fusion.

The disposable dust protective mask of so making makes its nose of being close to the user respectively and lower jaw position by launching gauffer part 1,1 '.

But the anti-dust respirator of this state is not a skin of being close to the user according to comparatively outstanding nose of face and lower jaw position, and the filter paper between its formation linearity sector, coupling part, so by the slit that forms between facial curve and the straight line filter paper, various dusts and harmful substance will be inhaled into human body.

Therefore, the anti-dust respirator that the utility model provides has formed nose and the lower jaw position curve projection 5,5 ' that is suitable for the user respectively at the two ends up and down of filter paper 2, make it be close to user's facial curve to greatest extent, basically eliminate the slit between face and the filter paper, significantly reduced the phenomenon that sucks dust and harmful substance.

Because this projection 5,5 ' is not to form by simple manufacturing process, thus in order to form above-mentioned projection 5,5 ', should be according to projection 5,5 ' cutting filter paper, and adhere to this reduction part by the high frequency heat amalgamation mode.

Therefore, the end that the end that is formed at gauffer part 1, the 1 ' end at above-mentioned filter paper two ends about in the of 2 and filter paper 2 forms certain intervals differs from 6, so that cutting filter paper 2, and carrying out high-frequency heat when merging, also can avoid and gauffer part 1,1 ' operation between mutual intervention.

In addition, above-mentioned end part 4,4 ' portion within it is provided with under 3,3 ' the state of being linked with, by high frequency heat converged fixed gauffer end and filter paper 2, and above-mentioned end part 4,4 ' end also can form end and differ from 6 ', to strengthen and to be linked with the coefficient of friction between 3,3 ', can freely adjust by artificial strength and be linked with 3,3 ' length, and can prevent that weight by anti-dust respirator itself and user's motion from causing and be linked with 3,3 ' move wearing the time spent, keep more stable wearing state.

As shown in Figure 4, because disposable dust protective mask can be close to user's face more, so it is particularly remarkable to reduce the effect that sucks harmful substances such as dust by the slit.
