Description
Technical field
The utility model relates to a kind of mouth mask, is specifically related to a kind of anti-dust respirator.
Background technology
Coal industry, metallurgy industry and wood furniture manufacturing working environment dust concentration are large, and workers with long time operation in the environment that this dust concentration is high is easy to suffer from all kinds of breathing problem, serious harm health.At present, the modal method of occupational disease caused for prevention dust wears mouth mask, and in prior art, mouth mask is mainly divided into two classes, one class is the Simple mask be only made up of individual layer or several layers of filtering material, and this Respirator structure is simple, cheap and easy to get, but dust-proof effect is poor, need often change.Another kind of with breather valve, the mouth mask of design comparison complexity, this kind of good dustproof effect, but expensive, carry inconvenience and often dress also uncomfortable.
Utility model content
The purpose of this utility model is exactly the defect in order to overcome prior art, provides a kind of structure relatively simple, the mouth mask of good dustproof effect.
The utility model is achieved through the following technical solutions:
A kind of anti-dust respirator, comprise mask body and be positioned at two ear-hangs in mask body, it is characterized in that, described mask body comprises skin, intermediate layer, internal layer, and described internal layer can furl the retracting device in mask body side.
Further, described retracting device is made up of slide rail, slide block and stay cord, and described slide block is positioned at slide rail inside, and described stay cord passes slide block and is fixedly connected with slide block.
Further, described slide rail comprises upper and lower two slide rails, and described stay cord, through two slide rails, forms loop.
Further, described internal layer is connected with described retracting device by described slide block.
Further, described slide block is lay respectively at least two in two slide rails.
Further, described intermediate layer is attached at inside described mask body skin.
Further, described intermediate layer is connected for detachable with described mask body skin.
Further, described stay cord part stretches out described mask body.
Further, described retracting device with inside described mask body skin by sewing up or bonding connection.
Compared with prior art, the beneficial effect that the utility model reaches is:
(1) Respirator structure of the present utility model is relatively simple, dresses Energy and comfort, good dustproof effect.
(2)retracting device is for furling mask body internal layer, and user can first furl inside mask body when leaving dust atmosphere, then the dust on the cover body skin of clean-up port, like this would not be contaminated easily with the mask body internal layer of human body close contact.
(3)in retracting device, the setting operation of slide rail, slide block, stay cord is simple, easy to use, the stay cord that user only needs pull portion structure to expose, under the drive of slide block mask body internal layer will furl in, convenient and swift.
(4)mask body intermediate layer is detachable layer, and this layer can change the intermediate layer of desired thickness or material requested pore size according to dust concentration size, dust granules size, can keep the filter effect of mouth mask the moment, extends mouth mask service life simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model mask body internal layer non-rolling when getting up;
Fig. 2 is the schematic diagram after the rolling of the utility model mask body internal layer is got up.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, a kind of anti-dust respirator that the utility model relates to comprises mask body and is positioned at two ear-hangs 2 in mask body, mask body comprises outer 1, internal layer 6, intermediate layer 7 and described internal layer 6 can furl the retracting device in mask body side, retracting device is by slide rail 4, slide block 5, stay cord 3 forms, it is inner that slide block 5 is positioned at slide rail 4, stay cord 3 passes slide block 5 and is fixedly connected with slide block 5, described wrap-up is positioned at inside mask body skin 1, with outer 1 by sew up or bonding way is connected, mask body intermediate layer 7 is attached at inside mask body skin 1, be positioned near nostril, the filter effect of dust is to external world improved while ensureing aeration.Mask body intermediate layer 7 and mask body skin 1 are detachable connections; as connected by double faced adhesive tape or VELCRO mode; mouth mask intermediate layer 7 is generally has certain thickness filtering material formation; the filter course in this intermediate layer 7 can also be the gas permeable material being soaked with water, also can protect user better like this in the environment having smog.Described mask body internal layer 6 is connected with retracting device by slide block 5, slide rail 4 comprises upper and lower two, stay cord 3 is through two slide rails, and forming loop, slide block 5 lays respectively in upper and lower two slide rails 4, totally two, stay cord 3 part extending port cover body, lay respectively at mask body both sides, corresponding with ear-hang 2, see Fig. 1 and Fig. 2.
When taking mouth mask, user can first pull side exposed pulling rod 3, and mask body internal layer 6 is pulled in side, and then removes the dust on mask body skin 1, now also can replace mask body intermediate layer 7 as required.When band muzzles, then pull opposite side exposed pulling rod 3, mouth mask internal layer 6 can be covered face.In the present embodiment, mouth mask internal layer is comfortable soft filter course, also ensure that the comfortableness that user wears while facilitating rolling.
Mask body internal layer 6 in the utility model can also form filter course by anti-biotic material, can also play antibacterial functions like this, ensure the health of user further while guarantee filter effect.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
