Technical Field
The invention belongs to a nose protection device for preventing water from entering the nose, in particular to a nose mask convenient for swimming.
Background
The standard breathing pattern of swimming in water is to inhale with the mouth and exhale with the nose (or exhale with both the mouth and the nose). This normal breathing pattern is primarily from a safety point of view, i.e. the nose is absolutely unable to enter water. The phenomenon that a person is choked by water is that water enters the airway of the person from the unobstructed nose hole. Since humans do not belong to animals living in water, the nose naturally does not have a function of closing itself to prevent water. The swimmer can only exhale with the nose and cannot inhale with the nose. For swimmers, despite breathing in a regular breathing pattern, water is not prevented from being forced or flushed into the nasal cavity during swimming. Because the long nostril of the human body is the opening condition of the gate, especially the large hole which is opened without obstruction, the water is not porous and can not be imported. Although the amount of water entering the nasal cavity sometimes does not reach a level that affects safety, it is still an insanitary concern. Especially, water in public swimming pools enters the nasal cavity, causing rhinitis or infectious diseases. The swimming pool contains chlorine chemical for disinfection, and allergic rhinitis is easy to occur after the chlorine chemical enters the nasal cavity. The nasal cavity is not easy to discharge after water enters the nasal cavity, and bacteria in the swimming pool are easy to attack through the nasal cavity. Swimmers often have a tendency to lose nasal water themselves when lowering their head, after a few hours or more after swimming. The pressure of water pressure on the nasal cavity of a swimmer is greatly increased because the swimmer usually takes the action of turning the big head down (standing upside down in water), so the swimmer needs to wear a nose clip to prevent water from entering the nasal cavity; for general swimmers, the problem of water inflow through the nose is also existed when performing forward rolling and body turning actions, but the time for handstand is relatively short. The nose clip is a traditional nose water-proof protective tool and is a nose water-proof protective tool which is universal for swimming all over the world. The principle of the nose clip is that the flesh of the two nose holes is closed after being extruded and deformed by the elasticity of the clip, namely, the flesh seals the nose holes to prevent water from entering the nasal cavity. The nose clip has poor reliability, and is difficult to position and clamp by using the lower part of a clip on two sides of the nose of a person with two inclined surfaces, and the nose clip is easy to slide down from the nose of the inclined surface by self under the lubrication action of water on the skin. Some nose clips have a thinner pull tape (the standard nose clip does not have the pull tape), but the pull tape only has the function of preventing the nose clip from falling off and ensuring that the nose clip cannot fall into water and cannot be found. Therefore, the nose clip can be used only for a short time and cannot be used for a long time. The other two nostrils are clamped, and basically dare to use the nose to exhale, and the exhalation nasal clamp falls off. There is no way to exhale using the mouth in its entirety, and the nose clip is not generally adaptable to being worn by a swimmer. The biggest defect of the nasal splint is that health is lost, a large number of capillary vessels exist on the inner membrane surface of a nasal orifice, and normal nasal organs are extruded for a long time under an abnormal state under the action of external force, so that the blood vessels are damaged easily to generate inflammation. Therefore, the rhinitis condition is aggravated when the nose clip is used by people with rhinitis, and the rhinitis is easy to obtain by people without rhinitis.
The nasal swimming mask of patent No. 201420575886.8 (my invention) solves the above problems, but the structure of the closed face of such large mask is relatively complex. In order to seal the two nasal orifices, the technical scheme that the whole nose is sealed by a solid cover is adopted, so that the weight and the protruding space of the face wear are increased, and the appearance is difficult to see. In addition, the nose mask needs to be provided with a special check valve to solve the problem of outward air exhaust of the nose, and the complexity of the structure of the nose mask is increased.
The defects of the prior art are mainly caused by conceptual errors. The muscles around the two nostril holes are mistakenly considered to be complicated in shape and are not as easily closed as the eye frames of swimming goggles. In addition, the nose is a convex organ in five sense organs, the organ is three-side leaning 'empty', has no limit object, only one side leaning 'ground' and no eye frame with limit like eyes exist, and is not fixed well.
Although the nasal swimming mask (inventor) with patent No. 2016205442370 is a brand-new invention, the sealing mode of the nasal splint and the sealing mode of the huge mask body are completely changed, the structure is not simplified to the simplest degree, and the sealing surface structure and the anti-displacement measure are opposite and have certain defects.
For example, the sealing and retention structure is relatively complex with two plugs projecting into the nostrils. The size and distance of the nose holes of people are too large, and the nose masks with various specifications are needed to meet the requirements of different people, so that the nose masks bring great troubles to processing, storage and sale. Meanwhile, compared with a nose clip, the structure is reformed by the dislocation and bone replacement, but still has the possibility that the nose clip can easily contact with the capillary vessels in the nose hole.
The embodiment of the structure of the convex plug is cancelled, the limiting function is lost, and the phenomenon that the sealing surface of the nose mask is easy to displace can occur. The reason for this is that the nose mask is not in the same position as the swimming goggles. The muscles on the four sides of the eyes naturally form a pit which can limit the displacement of the swimming goggles. The nose is an outwardly protruded organ, three sides around the nose are 'empty' and one side is 'ground', the natural limit condition is not provided, and in addition, the head band of the nose mask cannot be arranged too tightly, so that the sealing surface (the nose mask) can be displaced under the action of external force (water flow) during the use process, particularly during swimming, and the nose hole is exposed; another reason is that the skin surface grease contributes to the lubrication of this seal surface displacement, and therefore there is a potential for seal surfaces without the plug restriction to be displaced.
In order to solve the problem of adjusting the length of the headband, the headband can be manufactured on a plane by adopting a structure of cutting off the headband in the prior art, the headband meets the requirement of the plane of the headband, and then the headband is connected by an adjusting device, which is a device with a complex structure for the thin headband used by the nose mask.
Disclosure of Invention
Aiming at the defects, the invention aims to provide the swimming nose mask which has simpler structure, reliable positioning, good sealing effect, convenient operation and beautiful appearance; provides the swimming nose mask with simple manufacturing process and high production efficiency.
The technical scheme of the invention is that the nose mask for swimming is composed of a nose mask 2 made of silica gel and a head band 1, and is characterized in that the nose mask 2 is plate-shaped, the outer edge of the nose mask is approximately in a strip shape, the nose mask 2 has corresponding thickness, the sealing surface contacted with the nose is a rough surface, and the two ends of the transverse central line of the nose mask 2 are connected with the head band 1.
In one embodiment, the broad face of the annular head band 1 is in a plane 360 degrees from the plane of the valve 2.
In one embodiment, the rough surface of the sealing surface is a leather textured surface.
In one embodiment, the rough surface of the sealing surface is in the form of raised pits.
In one embodiment, the rough surface of the sealing surface is in the form of raised ribs.
In one embodiment, the wide face of the circular headband 1 is provided with wrinkles 6, and the circumference of the edge formed by the wrinkles of the inner bend 5 of the headband 1 is equal to the circumference of the edge of the outer bend 7 of the headband 1.
A method for manufacturing a swimming nose mask is characterized in that a wide surface of an annular head band 1 and a plane of a nose mask 2 are provided with a mold in a plane within the range of 360 degrees.
In one embodiment, the mold is opened by flattening the ferrule-shaped headband 1 into the shape of an athletic track.
The nose mask has the technical effect that the sealing surface of the nose mask is provided with a rough surface structure, so that the friction force between the sealing surface and the skin can be increased. In particular, the high points on the roughened surface of the mask under tension from the headband correspond to compression into the soft skin under a positive pressure. This is exaggerated from a microscopic perspective, and the nose mask is fixed to the nose as with the boat anchor. It is also a principle that what is physically called friction generation. The small measure can thoroughly abandon the structure with the convex plug, and has the significance of further simplifying the structure and improving the reliability and convenience of the sealing of the nose mask. With the structure that the sealing surface of the nose mask can be reliably positioned on the nose, the nose mask can be made into a plate-shaped silica gel nose mask with a structure with a corresponding thickness. Under the pulling force of the headband, including the water pressure, the plane of the plate-shaped silica gel nose mask can be automatically deformed and adjusted to have the shape of blocking muscles around the nostrils. The plate-shaped silica gel nose mask is matched with muscles around the nose holes in shape, so that the two unobstructed nose holes opened from the main door hole are blocked, any weak edge of the sealing surface of the nose mask can be opened when the nose needs to exhale outwards, and the nose mask can exhale outwards smoothly and unimpededly, so that the standard action of exhaling with the nose, which meets the swimming action requirement, is met. The silica gel nose cover is tensioned by the head band and sealed on the two nose holes at the central line, when the nose exhales outwards, the relatively thin nose cover and the head band have very good elasticity, at the moment, the nose cover overcomes the elasticity of the sealing surface, including the elasticity of the head band, and is opened easily, gas is discharged into water along the gaps around the nose cover, and when the exhaust is stopped, the silica gel nose cover is automatically closed under the action of the elasticity of the nose cover, the tension of the head band and the water pressure. Therefore, the nose mask functions as a check valve with only one opening and one closing. The significance of the nose mask is greater for the structure of the nose mask which can not be used by swimmers. For people who are not familiar with water, especially people who do not know the correct breathing method for swimming, the two nose holes opened in the large opening are completely shielded by the nose mask with the shape slightly larger than the shape of the nose holes, so that water can be completely prevented from entering the nasal cavity, and the occurrence of a water choking event is avoided, thereby being a safe protection measure. This is the only suitable protective gear for a non-swimmer. Because the protective tool of the nose clip can not be worn (can not be worn, can not be worn and can not be used) by a swimmer. The nose mask is not worn by a swimmer, and has no special point, and the two nose holes are shielded by the silica gel nose mask with the plate type structure, so that the state that the swimmer can not inhale air is achieved. The use of the mask can cultivate the breathing action which is not normalized by the swimmer (the swimming breathing action is an important technique which should be mastered by the swimmer, and the nose mask can force the swimmer not to use the nose to inhale). The nose mask with a simplified structure into a plate structure can be popularized as a sanitary appliance like the invention of a mask. The wearing mask is a sanitary appliance on the land; the nose cover is a sanitary tool in water. As whatever water enters the nasal cavity is an unsanitary and unhealthy thing. Therefore, the nose mask which is simple in structure and easy to wear is a novel sanitary protective clothing for swimming, can effectively protect the health of a swimmer, and enables swimming sports to be healthier and civilized like the invention of swimming goggles.
The nose mask with the silica gel plate-shaped structure is further simple in structure and almost has no any complex parts when being processed; when in use, the nose cover is aligned to the nose hole, and the head band is sleeved on the swimming cap according to the angle of 45 degrees, which is not like a nose clip and makes people not know how to wear the swimming cap; the user wears a silicon nose mask in a plate shape, which gives little feeling. The only sensation was that inhalation was not possible with the nose, as if rhinitis was obtained, and the nose was not breathable. The habit required to develop by swimming breathing regulation is that the person can only exhale and cannot inhale; the user wears a plate-shaped silica gel nose mask and only uses a thin and long head band to hang on the nose under relatively slight tension. Different from swimming pool, the requirement of pulling force of the head belt is large, and the swimming goggles are tightly buckled on the eye frames. The difference is mainly due to the different sealing requirements and principles, so that the eye frame is not marked after the swimming goggles are used.
The structure of combining the silica gel plate-shaped nose mask and the thin headband fully overcomes the prejudice of the concept of sealing the nostril channel. It is a simple technique that has not been used for years to close the two ostia, but it is stubborn to use the nasal splint to close the two open ostia in a painful squeezing manner. This is also a technical prejudice for the skilled man worldwide (as can be seen from the use of such painful and unsightly nose clips by athletes all over the world in swim style); the nose clip is used for clipping the nose flat by strong pressure, the water is prevented from entering the nose through the painful body deformation, and the situation that the nose is pinched by hands to prevent the nose from ventilating is solved. The two nose holes can be lightly blocked by a soft silica gel nose mask, and the soft silica gel nose mask is not used by a simple method when being placed, which belongs to a technical bias; the nose can be placed in a mode that the blocked nose can exhale without closing the nose completely; the nose is put on the nasal obstruction device to keep the original shape of the nose, and the simple method for blocking the nasal ostia of the five sense organs of a normal person is not needed, and the nose of the person is required to be pinched flat to take off the image of the person. The technical prejudice is that it is impossible to block the nasal orifice with a silica gel plate-like nasal valve. Under the action of the concept, the muscles at the two nostrils are thought to be more complicated than the eye frame muscles in shape, and the closing cannot be carried out at all without a limit backer.
The fact that a silica gel plate with the shape and size of the two nose holes and an annular thin head band are finished is how easy and beautiful swimming protectors. The nose mask and the head band are made into a whole, and almost no place can be seen to influence the five sense organs of a human. Especially, the colored nose mask is manufactured, like a wearing mask, the pull rope is used for covering the nose mask below the nose hole, the whole five sense organs still keep the original shape, and the five sense organs of a person are not influenced. The appearance of the nose mask is the same as that of swimming goggles, and the nose mask is a decoration for swimmers. It makes sense to replace the traditional, painful, disfiguring nose clip with such painless ornamentation. The most important significance is that unlike the nose clip which can not use the nose to exhale, the nose mask of the invention is a swimming nose protector which can keep the same with the swimming standard breathing mode; due to the different sealing concept of the nose mask, the elastic force requirement of the headband is different. In order to ensure the smooth opening of the nose mask, the thin and easy deformation of the head band is the structural characteristic of the nose mask, and the structural characteristic determines that a new manufacturing method can be used for opening the die so as to simplify the die. It will be apparent to those skilled in the art that the split headband can be connected by an adjustment device to form a circular headband, which is the only manufacturing method that achieves the purpose of adjusting the length of the headband while the wide side of the headband is in a plane. For closed loop headband without adjustment means made on one plane, it is considered by those skilled in the art to be impossible; second, it is not possible to have a swimming harness headband without an adjustment device.
In fact, the size of the head of the person is within a corresponding range, and due to the special nature of the mask closure, the range of spring force requirements is relatively within an area that is not as thin as the headband of swimming goggles would require. The nose mask headband of the invention is just like a swimming cap, and has only one specification, but is suitable for all people. The thin nature of the headband readily deforms the elongated structure and can be machined completely in one plane. In accordance with the above concepts, the headband of the present invention directly produces a closed circular headband with a broad face in a plane. The structure not only saves plastic parts required by the adjusting device, but also has the characteristics of simpler structure, simple processing technology, convenient use and attractive package. The structure is simple, and only one annular head belt is provided with the plate-shaped nose mask for blocking the nose holes. Simply speaking, the swimming cap is a circular ferrule, and the swimming cap can be hung on the top of the swimming cap by sleeving on the head of the circular ferrule; during processing, the annular head band is flattened into a track-and-field runway shape for processing, and mass production can be realized by a pair of simple dies; in order to open the track-and-field-track-shaped headband and change the track-and-field-track-shaped headband into a normally used annular headband, a corrugated structure is arranged on the wide surface at the curve of the track shape, namely, the annular headband with the wide surface all perpendicular to the horizontal plane is folded into a corrugated shape, and the wide surface all parallel to the horizontal plane. The wrinkle structure enables the wide surface part of the curve and the headband at the rear part to stand together after being opened, so that the longitudinal line of each wide surface of the headband can be parallel to the plane of the nose mask, and the nose mask can be used only by sleeving the headband on the head of a swimmer; when swimming, the nose cover ensures that the two nose holes are blocked without water inlet and the breath is smooth under the elastic action of the head belt; the annular head band is flattened into the shape of the track and field sports track to open the die, so that the area of the die can be reduced, the cost of the die is saved, and the production efficiency is improved; the wide surfaces of the two 'runway curves' are provided with a wrinkle structure, a planar annular head band comes out of the planar mould, and the wrinkle structure is changed into a three-dimensional annular head band after the annular head band is opened, namely the wide surface longitudinal line of the whole annular head band is parallel to the plane longitudinal line of the nose mask, or the wide surface and the plane of the nose mask are all perpendicular to the horizontal plane, so that the head band in the shape of a sleeve head required by use is formed; the annular head band is flattened into a nose mask in the shape of a track and field sports track and is packaged in the natural state of the product. For example, the nose mask, the trademark on the nose mask and the head band can display all the characteristics of the product on one plane by using plastic suction for packaging, and the nose mask is simple and attractive.

Detailed Description
Referring to fig. 1, the nose mask 2 and the headband 1 are made as a single ferrule made of silicone material. The sealing surface of the nose cup 2 is provided with a leather pattern, which is only slightly rougher than the smooth surface, but which is sufficient to ensure that the nose cup cannot be displaced for soft skin. The rough surface can ensure the positioning and sealing effect and does not influence the wearing comfort of a user; in a second embodiment of the rough surface of the nose mask, the sealing surface can be provided with pits, the rough surface of the pits is rougher than that of the leather surface, and the height of the pits is controlled according to the precondition of comfortable wearing of a user; in a third embodiment, a plurality of ridges may be provided on the sealing surface, in the same manner. The sealing surface can be arranged on the front and back surfaces of the nose cover, so that a user can wear the nose cover conveniently without dividing the front and back surfaces. The other side of the nose mask is provided with a trademark, and the nose mask is also a sealing surface which can be used on two sides. The third embodiment is the above third embodiment, that is, the concave-convex structure of the trademark is formed by providing the sealing surface with the striated edge, which is also a way of rough surface.
The nose mask 2 is connected with two ends of the annular headband 1 at two ends of a longitudinal center line to form a closed loop. The center line of the longitudinal end of the nose mask 2 and the center lines of the wide faces of the two ends of the head band 1 are on the same line, and the connecting part of the end point of the head band 1 and the nose mask 2 is provided with a circular arc connection to increase the strength, or a triangular wide face end connection mode can be adopted; the plane of the nose mask 2 is in the same plane with the wide face of the headband 1. The plate-shaped nose mask 2 has a corresponding thickness, which means that the plate-shaped nose mask 2 can be automatically adjusted to a closed surface adapted to the shape of muscles around the nasal orifices under the tension of the headband on the plane, so as to achieve the effect of closing the two nasal orifices. The nose mask 2 can be ensured not to be folded into wrinkles in the longitudinal direction, which influences the sealing of the nose mask 2; when the nose is used for exhausting, the nose is easy to deform to generate an exhaust channel, and the exhaust is stopped to automatically close and seal; the appearance 3 of the upper end of the nose cover 2 is in a circular arc shape which is similar to the shape of the upper part of the nose, and the nose hole can be sealed according to the principle. Because the noses of people are different in size, the requirement of all people can be met by taking an approximate value, the requirement is not completely matched with the noses from the sealing point of view, the nose cover 2 can be slightly longer, namely is in a strip shape, a certain adjusting space is left, and the two nose holes can be reliably closed; the lower end profile 9 of the mask 2 is inwardly directed in a small circular arc to fit over the lower part of the nose, i.e. the upper part of the lips. The nose hole surface is matched with the folding angle at the upper part of the lips, can also reach a bending state when in use, and is bent into a bending shape with curvature like the sealing surface of a swimming goggles for sealing. In short, a strip-shaped silicone plate is the main body shape of the nose mask 2, and the upper end shape 3 of the nose mask 2 and the lower end shape 9 of the nose mask 2 in a longitudinal plate shape can be slightly adjusted.
Either the swimming goggles or the headband of the nasal mask of the present invention require a wide face and a narrow face to distribute pressure against the skin with the wide face. The headband 1 of the present invention does not require as much elastic force as swimming goggles, and can appropriately reduce the thickness of the narrow side and increase the width of the wide side to reduce the pressure on the skin, thereby improving the comfort level. Therefore, the structure of the nose mask headband 1 is a thin long-strip ring-shaped elastic band, which is the preferred embodiment of the present invention.
For a headband with an adjustment device that directly connects the two end structures of the headband 1, it is not easy to manufacture the wide face of the headband on one plane. However, the basic requirement of such a construction is to be achieved by providing an adjustment device which requires an extra length of the headband 1, which is relatively complicated.
The present invention adopts a method of manufacturing all the wide faces of the headband 1 and the plane of the nose mask 2 on a plane within 360 degrees. In order to reduce the area of the die, the die is designed into an annular ring structure in the shape of a track and field runway.
As for the structure that the two ends of the circular head band 1 are directly connected with the two ends of the nose mask 2, the invention adopts the method that the circular head band is flattened into the shape of the track and field sports to open the mould, namely the head band 1 is directly manufactured into the shape of the track and field sports. The annular head band 1 is made in the shape of a runway bend, so that the mould is simplest and the processing is simplest. In order to solve the problem that the headband 1 does not conform to the actual three-dimensional shape caused by the 'runway curve' on the plane, wrinkles 6 can be arranged on the plane of the inner curve, and the length of the wrinkles 6 is calculated in advance, so that the perimeter of the edge of the headband 1 of the inner curve 5 (the inner diameter of the curve) of the wide face of the headband is equal to the perimeter of the edge of the outer curve 7 (the outer diameter of the curve). After the headband 1 with the wrinkles 6 is unfolded, the
When the headband 1 is not pulled like swimming goggles, it does not need strict requirements for adjustment length like swimming goggles, which is the fundamental reason why the nose mask can use the circular headband 1 without adjustment length. Thus, designing the endless headband 1 to be of an average length is fully satisfactory for the general needs of swimmers. The swimming goggle headband is also a special difference with the swimming goggle headband with large elasticity and is a special difference of the design concept.
In order to make the headband 1 suitable for being worn by children or people with a particularly small head shape, or for a person with special needs to conveniently adjust the length of the circular headband 1, a plurality of raised edges are arranged on the back headband 1 (under the circular track), the structure can tie the two folded headband 1 by wires to reduce the length of the standard headband 1, and the raised edges are the limiting device adjusting devices. Of course, it is also an embodiment that the headband 1 is provided with the adjusting tab disconnected at the rear.
The headband 1 can also be provided with branch strips near the passing ears, and earplugs are arranged on the branch strips, namely, the swimming nose mask and the earplugs are combined together to facilitate the requirements of the swimmers. The earplug can be mounted by bonding or sleeving and is fixed by elasticity.
