Description

One protects volume formula filer element type band snorkel mouth mask

Technical field

The utility model belongs to mouth mask, particularly relates to one and protects volume formula filer element type band snorkel mouth mask.

Background technology

Traditional mouth mask is multilayer gauze or non-woven fabrics overlap is fabricated to mouth mask, and during use, mouth mask covers mouth and nose, and hooking band is used for being hooked on ear.According to patent notes such as CN201520221891, CN201420177257, illustrate some changes to mouth mask.Below all cannot solve that existing mouth mask flow is little, respiratory resistance is big, the effective filter cloth of mouth mask utilizes insufficient problem, also have aesthetic problem, expiration can allow the problem that glasses haze, the problem wearing inconvenience, face is covered uncomfortable, feel airtight problem, mouthful mouth separation problem, and can not wear masks the problems such as feeding edge drinks water on limit.The open one of the utility model protects volume formula filer element type band snorkel mouth mask.

Summary of the invention

In order to solution problem above, the wearing mode of the large scale ground change tradition mouth mask of the utility model innovation, revolutionary mouth mask is combined with protecting volume, air purifier, air filter etc., mouth mask is worn on forehead, it is enclosed within head by elastic cord, by snorkel, filtered air is transported to nasal cavity.And protect the filter core within volume formula mouth mask, also use for reference the design of air filter or air purifier, used Wrinkled, increase effective filtration area.The utility model solves the scheme of problem and arranges the volume of protecting, headband, mouth mask filter core, snorkel, terminal air supply plant exactly, volume-mouth mask will be protected with headband to be worn on forehead, connect nose with snorkel, release mouth mask and face is taken, effectively utilize the area of forehead.Meanwhile, the volume that the protects formula mouth mask being worn on forehead, is also a kind of decoration, better appearance.

Design inspiration of the present utility model comes from a kind of device of a kind of palm size being worn over forehead position in animation " the fire shadow person of bearing ", is called " protecting volume ".Literal meaning should be a kind of device protecting forehead.This volume that protects is arranged between hair and glasses, and the most square plus some radians, main body is made of stainless steel, and is connected with a strap, ties up on the head of the person of bearing.This volume that protects does not has any actual functional capability, does not the most exist with real life, and simply animation Cosplay fan may use these equipment.It is true that in reality, the most do not protect this thing of volume.The volume that protects a kind of animation translation call.

In conjunction with our country's present case, air pollution ratio is more serious, wears mouth mask trip and the most uniquely selects.Current mouth mask is all to be worn on mouth.The skin around mouth is close to by mouth mask, it is intended to creates the space of an isolation.This space being close to cause between nose and mouth mask is the most little, and the effective area of mouth mask that air flows through can be allowed during breathing very limited.It is big that such situation has also resulted in respiratory resistance.Perhaps people's respiratory resistance of Roman nose can be a little bit smaller, because mouth mask jack-up is come by Roman nose, allows mouth mask more participate in air filtering.And mouth mask seems the most really to be adjacent to face, it is adjacent to face in other words and is not easy very much.Because the feature of face is had nothing in common with each other, even if mouth mask is soft, can not really create the space of an isolation.A lot of mouth masks of 3m, during air-breathing, air is all to enter respiratory system from the space between nose and mouth mask, air now without filtration, the dirtiest air.Major part mouth mask is not with the most just accomplishing sealing.One plastic housing mouth mask the most fiery of Singapore, main body is a plastic housing being worn over nose and mouth, and both sides arrange two pieces of filter discs, although they recognize the importance of sealing, takes plastic housing to be propped up by mouth mask filter disc, but plastic housing is not accomplished to seal too.Mouth mask does not play any effect in this case, simply comforts at heart.During expiration, air backs down mouth mask and the contact of face, can go out from each place.When there being people's wearing spectacles, the hot gas of exhalation is easy to haze through glasses.So present mouth mask did not the most just have the effect of air filtering, but also look for trouble.Decoration simply purely and warming.

I likes running myself, especially yearns for and running marathon.Running into mist if run marathon boundless, that really allows people be entangled with very much.Running is not configured to health？Existing mouth mask neither one is the design that runs marathon.Searching for marathon mouth mask in Taobao, result is 0.Tradition mouth mask respiratory resistance is so big, runs and just tires out dying for a moment.

Run marathon and need the biggest air intake-exhaust flow.This will design the mouth mask of a kind of super-flow.We obtain inspiration from the air filter of automobile.Automobile to be breathed hundreds of time for one second, inhales the air that several liters do not wait every time, the same with us works in severe air ambient.Automobile realizes super-flow by the large-area filter core of a kind of Wrinkled.And ensureing that inspiratory resistance is less, air-breathing is smooth and easy.

By inspiration both, we design a kind of air filtering core with Wrinkled, are worn on forehead, by the volume that the protects formula mouth mask of snorkel conveying clean air to nose.You make him protect volume or mouth mask can.

The utility model is that one protects volume formula filer element type band snorkel mouth mask.Mouth mask is worn on forehead position, then connects nose with snorkel.By arrange headband, protect volume, snorkel, mouth mask filter core, terminal air supply plant realize.Headband is connected to Hu Eshang, and the volume that will protect is tied up on user's forehead.Mouth mask filter core is arranged in the volume of protecting, and the volume of protecting arranges gas outlet and connects snorkel, and snorkel reconnects terminal air supply plant and ozone is supplied to user.It is mainly used in the mouth mask worn when running marathon.

This mouth mask passes through elastic cord, such as broadside elastic cord, is worn on the forehead position of user.Mask main body had both been protected volume main body and had both been protected volume formula mask main body, can claim volume cover main body or mask main body.Herein referred mask main body is essentially equivalent to protect volume main body.But protecting this concept of volume should be to include mask main body and decoration baffle or mouth mask support below.The volume that protects is for connecting the parts such as headband and installing port cover filter core, snorkel.Mask main body part be provided with for installing port cover filter core die cavity.Mouth mask filter core is arranged in die cavity, and cavity wall is sealed by rubber seal or silica gel sealing ring, O, y-type seal ring etc..So two sides of mouth mask filter core, one side is outside air, and one side is then to close space.The cooperation of such die cavity and sealing ring is only set, can truly realize the isolation of air.The purpose that the cooperation utilizing mouth mask and face attempts to reach isolation is the most unworkable.One gas outlet is set in mask main body part, is used for snorkel of plugging into.Two gas outlets can also be set in fact, connect two snorkels.Gas outlet can be arranged on the centre of mouth mask, or the both sides of mouth mask.Being arranged on centre, snorkel comes nasal cavity under the direction of the bridge of the nose；If being arranged on both sides, snorkel must turn round, it is also possible to snorkel connect about two gas outlets, then in the middle of the U-shaped lower position to nostril, then on snorkel, open two apertures lead to nasal cavity.Both, two U-shaped ends pick out gas port, and in bottom indirect nostril.This set is exactly conventional medical Oxygen tube, and concrete name is called medical pair of nasal obstruction oxygen inhalation tube.The most just not having snorkel, the venthole directly buying the both sides that double nasal obstruction oxygen inhalation tube plugs mask main body part is the most permissible.Gas outlet setting in mask main body is the most flexibly, almost can be arranged on any position, as long as the sealing not destroying mouth mask filter core is the most permissible.And, arranging of venthole can change two the relative spaces caused by the sealing of mouth mask filter core.If venthole is in the position of the inside relatively, then the space inside mouth mask filter core is exactly the space of clean air；If gas outlet is outside, and mouth mask filter core is inside, then air just should be drawn onto outside from the inside, and outside now is then the space of the clean air of opposing seal, and the inside of relative mask main body then leads directly to air.Our the preferably the inside (namely contacting the side of forehead) of mask main body is to close, and outside is the most open to atmosphere.It is the simplest that the inside wants straight-through air, opens several hole the most permissible on inwall.Our embodiment will have a snorkel outside, and outside, both one was headed on direction air inlet a mask main body from user, and one from user's forehead both the inside air inlet.Both are respectively arranged with pluses and minuses.

Mask main body is provided with " day " type and buckles, and is used for connecting headband.Headband is directly through inside a day type buckles, it becomes possible to locking.We use broadside elastic cord, it is also possible to directly use cloth belt, or the silica gel headband of the luntttes of diving.Broadside elastic cord is worn more convenient and comfortable.Silica gel headband seems to compare medical type, compares clean hygiene.Day type is buckled and is also easier adjust length and then adjust degree of tightness.The various hasps that can also use rag trade case and bag industry can realize.

The fold of mouth mask filter core is to increase the key of air effective discharge area.Processing so we take fold, just as the air filter of automobile, spreading out is a lot of times of its originally occupied area.The filter cloth of mouth mask filter core we use and various can filter PM2.5's or other have various specific function.The mouth mask filter core taking fold process is arranged in mask main body by we, it is possible to the effective air that increases is by area, thus increases air mass flow, reduces respiratory resistance.The needs of marathon can be adapted to.And owing to whole filter clothes can participate in air filtering, its filter effect is also better than the mouth mask of the common form using identical filter cloth material.The air that whole lung needs will be filtered in the place of common one nostril size of mouth mask, and we have employed after fold processes the area ratio whole mouth mask of common mouth mask will the most several times.The mouth mask actual filtration area so increased is the hundred times of common mouth mask.So expiratory resistance will be greatly reduced, and charge flow rate can be greatly increased.Even if in fact not designing fold on this mouth mask filter core, mouth mask filter core is only a plane, and the effective filtration area of the mouth mask filter core being arranged in our scheme is still big than common mouth mask, still can reach the purpose of our solving practical problems.Arranging fold can allow effect more preferable.The mode that mouth mask filter core is arranged in mask main body can be that extruding is entered, it is also possible to arranges screw, it is also possible to clamp mouth mask filter core with mask main body and mouth mask split, just as the mounting means of automotive air cleaner core, clips mouth mask filter core.Multiple mouth mask filter core can be mounted side by side in one mouth mask, and function is the same or complementation can.The utility model is not related to the innovation of the material of filter cloth.

This device is additionally provided with decoration baffle, is used for covering mouth mask filter core.It is mounted with from front, the mask main body of mouth mask filter core looks that some is ugly.One decoration baffle is installed and blocks the structure within mouth mask filter core and mask main body and part.Some decorations, such as pattern and word etc. can also be printed on decoration baffle.Decoration baffle can use for reference the volume that the protects design in " the fire shadow person of bearing " so that it is more good-looking.Decorative panel can be screwed on by screw in being arranged on mask main body, or by blind rivet riveting up, or by plastic clip buckle up.When including air filtering core, the interface of snorkel outside time, decoration baffle can also be not provided with, or arranges a lot of openwork part on decorative panel.So the wind head-on blown can also can either be utilized to reduce inspiratory resistance further by oncoming blast inlet shroud when cycling, running.

Snorkel should use the material of softness, such as silicone gum rubber etc..And should there is no smell.So can adapt to the shape of face of different people.Snorkel is responsible for connecting mask main body and nasal cavity, is sucked in by ozone, muddy air exhalation is gone.Snorkel one end interface cover main body, other end connects nose.Concrete and nose connected mode can be to separate two tips of supplying gas, and leads to two nostrils respectively, it is also possible to be a big resin retainer, cover on user's nose, similar medical oxygen therapy cover.Snorkel should be the most transparent, there is sense and interference to reduce.Snorkel connects one end of nose, it is also possible to arrange one-way breather valve door, and when i.e. exhaling, waste gas does not lead to mask main body, but directly discharges at snorkel end, and during air-breathing, this valve is then automatically to remain turned-off.The design of this expiration valve can be found in the mouth mask of 3M, or the most common similar family expenses fume exhausting check valve.The nose of snorkel can also directly connect a custom-designed nostril adapter or silica gel nose cup.Come by this nostril adapter and nose communicates, and integrated one-way breather valve door function.Snorkel can also arrange many, one, nostril.

Tracheae is picked in described adapter one end, nostril, and other end is divided into two parts and leads to nostril.One-way breather valve door it is also provided with, it is ensured that during expiration, waste gas can quickly be discharged in the adapter of nostril.Two channel ends towards nostril are provided with seal member, it is ensured that the sealing between nostril adapter and nostril.This seal member can be sponge, it is also possible to be silica gel sealing ring.We term it silica gel nasal obstruction.

So nostril adapter both can be single parts, it is also possible to integrate with snorkel.

Described silica gel nose cup covers on nose.Similar with Medical oxygen-absorption cover but do not cover face, it is simply that a little bit smaller, only cover nose.On medical breathing machine, Medical oxygen-absorption equipment, this nose cup is called lung ventilator nose cup or ventilator mask, lung ventilator silica gel nose cup.This nose cup is specially designed for patient's long periods of wear of respiratory disease.Coordinate with lung ventilator, provide clean oxygen to patient.When the nose cup using this bell-type rather than the nostril adapter filling in nostril, need to be fixed by nose cup, be pressed on nose.Can use and binding device is set at nose cup again, both include that headband had two fixing bandages altogether, mode fix nose cup.Can also be that described snorkel is changed to hard plastic hollow pipe, such as hollow aluminum pipe, hollow copper pipe or the hollow plastic pipe with plasticity.(plasticity: suffered external force has the character that can forever retain deformation after exceeding its elastic limit .) this hard plastic hollow pipe, has preferable toughness, it is possible to carry out permanent being plastically deformed under sufficiently large External Force Acting, and keep this state.Preferably use hollow aluminum pipe, there is preferably deformation and keep the ability of deformation.Thus can be only with a headband, then nose cup leans on the pressure of snorkel to be fixed on nose by nose cup.Both, described snorkel both can be the soft elastic materials such as silicone tube, it is also possible to is the toughness plastic materials such as aluminum pipe.Snorkel now is the equal of hard tube.The purpose being plastically deformed mainly facilitates user oneself to adjust the position of nose cup and the compactness contacted.If snorkel is rigidity completely, volume and nose cup are protected in fixing connection, then nose cup is by bad adjustment position.

The most do not hide face due to the utility model, so user can also use nose, exhale with face, the most more efficient, it is more suitable for horse race.The most also one-way breather valve is avoided the need for.

The aspirating end of snorkel can also is that and is connected with face, because compared clean through filtered air, it is possible to as diving oxygen tank is the same with the connected mode of face, be contained in in the registered permanent residence by a device sucked.Now snorkel is exactly to be connected with oral cavity adapter.Correlation technique refers to diving field.This device general call in diving field is called " respiratory siphon " and " being difficult to articulate ".Adopt and can also be vented by face air-breathing nose in this way, it is also possible to outlet valve is set.Current mouth mask all can not realize muzzle and separate with breathing mask.And no matter our utility model is to use nostril adapter or be connected with face, muzzle can be realized and separate.Such equipment is more needed during motion.

Above-described nostril adapter, tip of supplying gas, nose cup, oral cavity adapter, be terminal air supply plant at this summary and induction.

Mask main body can be a part, it is also possible to be several assembling parts.In mask main body, the die cavity for installing port cover filter core can take up whole mask main body, it is also possible to only accounts for sub-fraction.Particularly, two or more cavitys can be set in mask main body, interconnect, thus multiple mouth mask filter core is installed, pass air through multistage filtering.Such as we will design a kind of sweet osmanthus mouth mask filter core, while filtering noxious refuse, using the teaching of the invention it is possible to provide light ecosystem fragrance of osmanthus.We will design a kind of special except formaldehyde for another example, or sweat fishy smell, or the mouth mask filter core of pollen, selects for special circumstances such as new house finishing, gymnasium exercise, times in spring.When multiple mouth mask filter core being installed in mask main body, if thickness low LCL front and back, it is also possible to the die cavity about design.

Protect the part that volume contacts with forehead, it is also possible to padded coaming is set, such as sponge, foamed silica gel, bipeltate etc., allow wear more comfortable.

It is true that by above-described mouth mask, the volume of protecting can also be worn on the back side of head when that user wearing.Now snorkel will be grown a bit, deform, and curved curved go, and be thrown to above nose.This is the predictable added beneficial effect of the design.
