Description

Cap, protective cover and preparation method thereof

Technical Field

The invention relates to a hat, a protective cover and a preparation method thereof, and belongs to the technical field of daily protective articles.

Background

In areas with low air temperature, people often wear hoods or masks to block cold air. Particularly, for a rider of a bicycle or a motorcycle, the rider mostly needs to wear a head cover capable of protecting the face in winter because of no windshield. Under the influence of direct sunlight, people usually need to wear sun-shading hats when going out outdoors, and need to wear a face mask when encountering sand or dust. In addition, in some special industries, it is also necessary to wear a mask. For example, welders need to avoid ultraviolet radiation, cooks need to prevent hot oil from splashing on the face, food attendants need to prevent spit from flying into dishes, doctors need to prevent infectious viruses from being introduced into the body, and so on.

In the prior art, the connection mode of the mask and the cap can be divided into a detachable mode and a non-detachable mode. For non-detachable connection, such as sewing the brim to the mask, the mask cannot be reused although the mask and the hat are tightly connected. For repeated use of the mask, it is often necessary to provide it with a detachable connection.

In a detachable connection, CN204744602U discloses a welding protection device, in which a face mask is connected with a helmet through a face mask rotating shaft. However, the mask can be detached only by taking down the cap, which is inconvenient to use. CN220520160U discloses a foam-preventing mask adapted to a head-mounted device, which is fixed by a buckle and a connecting belt, and also has the problem of inconvenient installation and disassembly.

CN 205648974U discloses that magnetic components are arranged on both sides of the face mask, so that the face mask is fixed to the cap cover through magnetism. However, the one-piece cap structure cannot effectively protect eyes.

In addition, in the prior art, a plurality of novel structures of the protective cover and the cap are proposed, but the structures are not designed simply, and the implementation has great problems, such as too many processes, too much cost and the like.

Disclosure of Invention

The invention aims to solve the technical problem that after the mask is used, the mask and the cap are inconvenient to disassemble; when the mask is ready for use, the mask and the cap are inconvenient to mount.

One of the purposes of the invention is that the mask and the hat can be assembled and disassembled by one hand on the premise that a wearer does not take off the hat.

The invention also aims to optimize the cap process, and provides a method for ensuring the cap to be produced at lower cost and simultaneously keeping better quality.

In order to solve the technical problems, the invention provides a hat which comprises a hat body and a visor, wherein a first magnetic part is arranged on the lower surface and/or inside of the visor and is used for being connected with a mask which is arranged below the visor and is provided with a second magnetic part through magnetic attraction.

In some embodiments, the visor is made of only one plastic layer, and the first magnetically attractable element is mounted to the lower surface of the plastic layer (including being directly fixed to the lower surface, embedded within the plastic layer, or partially embedded within the plastic layer).

In some embodiments, the visor includes a surface layer on the upper and lower surfaces and a core layer between the upper and lower surfaces, and the first magnetically attractive element is fixed in the core layer. The first magnetic part is arranged on the lower surface of the core layer (embedded in the core layer or embedded in the core layer, etc.).

The first magnetic part is arranged on the lower surface and comprises a first magnetic part fixed (such as adhered) on the lower surface, and the first magnetic part can form a bulge after being arranged; also includes embedding the core layer, so that the lower surface can be kept completely flat. When the first magnetic part is partially embedded in the lower surface, if the depth of the first mounting hole is the same as the thickness of the first magnetic part, the lower surface can be kept completely flat; if the depth of the first mounting hole is different from the thickness of the first magnetic member, a portion of the first magnetic member may protrude or a portion of the first mounting hole may be recessed.

In some technical schemes, the visor comprises surface layers positioned on the upper surface and the lower surface and a core layer positioned between the upper surface and the lower surface, a hot melt adhesive layer is further arranged between the surface layers and the core layer, a first mounting hole is formed in the core layer, and the first magnetic attraction piece is positioned in the first mounting hole.

In some embodiments, the core layer is made of high density polyethylene. High density polyethylene HDPE has good hot workability and is often used in the manufacture of visor caps.

In some technical schemes, a waterproof film layer is arranged between the core layer and the surface layer.

The waterproof membrane layer is a hot melt adhesive layer. The hot melt adhesive layer is a plastic adhesive, and the physical state of the hot melt adhesive layer changes along with the change of temperature in a certain temperature range. After being heated, the hot melt adhesive layer can bond the surface layer and the core layer and can form a waterproof effect.

Typically, the core layer has a hardness greater than the hardness of the face layer. The core layer maintains the shape of the visor, and the surface layer is used for decorating the visor.

In some embodiments, the visor is crescent shaped. The visor can be plane or curved. When bent, the two sides of the visor are lower than the middle.

In some embodiments, the visor is structured as: including the surface course that is located upper and lower surface and the sandwich layer that is located between the upper and lower surface, still be equipped with the hot melt adhesive layer between surface course and sandwich layer, be equipped with first mounting hole (can be the through-hole that runs through the sandwich layer) in sandwich layer (sandwich layer bottom), first magnetism is inhaled the piece and is located first mounting hole.

The invention can also solve the preparation problem of the cap with the magnetic attraction function, and provides a preparation method of the cap, which comprises the following steps:

(1) a first mounting hole is formed in a core layer of the visor;

(2) mounting (preferably embedding) a first magnetic member in a first mounting hole of a core layer;

(3) arranging a hot melt adhesive layer and a surface layer on the upper and lower surfaces of the core layer, so that the hot melt adhesive layer is positioned between the core layer and the surface layer;

(4) heating to melt the hot melt adhesive layer to bond the face layer and the core layer.

Preferably, after the first magnetic member is inserted into the first mounting hole, a single-sided adhesive (e.g., PET adhesive) is used to temporarily seal the first mounting hole, so as to prevent the magnet from falling off during the next process.

Preferably, one side of the two surface layers is coated with the hot melt adhesive in advance, and then the two surface layers coated with the hot melt adhesive in advance are combined with the core layer.

The traditional sewing machine cannot perform efficient sewing operation due to the influence of the magnetic force of the first magnetic suction piece, and meanwhile, sewing can be performed by penetrating the first magnetic suction piece, so that the surface layer and the core layer are bonded by using the hot melt adhesive to replace the traditional sewing process. The invention sews two surface layers, and a gap (other three sides are sewed) to be filled into the core layer is reserved; after the core layer is arranged, the unsewn edges of the two surface layers and the cap body are sewn together. And heating to melt the hot melt adhesive, so that the surface layer and the core layer can be bonded, and the closing-in between the surface layers is realized.

In some embodiments, the hot melt adhesive generally needs to be hot-melted twice, and the first time is pre-bonding, that is, the hot melt adhesive is firstly fixed on the surface layer or the core layer through hot melting, and then the surface layer and the core layer are bonded through hot melting after the core layer is filled. For example, in the step (3), the upper and lower surfaces of the core layer are provided with the hot melt adhesive layers, and the hot melt adhesive layers are heated to be melted so as to bond the core layer and the hot melt adhesive layers on the upper and lower surfaces in advance; after the surface layer is arranged, the surface layer is heated and melted once, and the surface layer and the core layer are bonded in advance; or, arranging a hot melt adhesive layer on the inner surface of the surface layer, heating to melt the hot melt adhesive layer so as to bond the hot melt adhesive layer and the core layer in advance, and then heating and melting once after the surface layer is arranged in the surface layer so as to bond the surface layer and the core layer.

Considering that part of the magnets are not resistant to high temperature, and the heating of the hot melt adhesive in the step (4) may have adverse effect on the magnetism of the magnets, the invention provides two solutions: firstly, a high-temperature resistant magnet is adopted, so that the magnetic force of the magnet is not obviously influenced; however, such materials are expensive and cost prohibitive for conventional protective articles. Secondly, in the step (2), a first magnetic part without magnetism is selected for installation; and (5) after the hot melt adhesive is heated in the step (4), magnetizing the first magnetic suction piece. Of course, even if the first magnetic attracting member having magnetism is selected in step (2), if the magnetism is considered to have declined; and (4) magnetizing can also be carried out after the step (4).

The cap and the mask are connected through magnetic attraction to form the protective cover. The protective cover comprises a face mask and a cap with a visor, wherein the face mask is detachably connected below the visor, and the detachable connection is magnetic attraction connection.

The bill has a certain stiffness to maintain the basic shape of the cap. In the prior art, it is usually necessary to provide a hard material layer in the visor, such as a plastic layer, cardboard, wood, etc. Because the visor is hard, the mask is connected below the visor through magnetic attraction, and when the mask needs to be detached, the mask can be detached from the visor by directly pulling the mask downwards with force; when the helmet is required to be installed, the helmet cover is close to the visor, and the helmet cover can be adsorbed and fixed by the magnetic force of the visor. Thus, the mask can be detached and installed without taking off the cap.

In some embodiments, the thickness of the hard material layer is 1-15mm, preferably 2-12mm, and more preferably 4-8 mm.

In some embodiments, the first magnetically attractable element can be completely encapsulated within a plastic layer (core layer) of the visor. Thus, the rusting can be prevented to the maximum extent, but the plastic layer with the thickness less than 1.5mm is difficult to prepare in the prior art based on the factors of the flowability of the plastic and the like. And first magnetism is inhaled the piece and is encapsulated in the plastic layer that is greater than 1.5mm thickness, and magnetic loss is very big, and it is limited to inhale the adsorption affinity of piece to the second, has influenced the stability of face guard installation.

In the detachable connection mode, in addition to the magnetic connection, if other detachable modes are attached, the technical problems of inconvenient detachment and installation still exist.

In some technical schemes, a first magnetic part is embedded in the visor, a mask connecting part is arranged at the upper edge of the mask body, a second magnetic part is arranged in the mask connecting part, and the mask is fixed below the visor through the magnetic attraction between the first magnetic part and the second magnetic part.

At the moment, the first magnetic attraction piece is positioned in the cap, the first magnetic attraction piece cannot influence the attractiveness of the cap, but an interlayer exists between the first magnetic attraction piece and the second magnetic attraction piece, so that the magnetic attraction acting force is reduced to a greater or lesser extent.

In some technical schemes, a hat connecting piece is arranged on the lower surface of the visor, and a first magnetic piece is arranged on the hat connecting piece; the upper edge of the mask body is provided with a mask connecting piece, the mask connecting piece is provided with a second magnetic attraction piece, and the mask is fixed below the visor through the magnetic attraction force between the first magnetic attraction piece and the second magnetic attraction piece.

At the moment, the first magnetic attraction piece is positioned on the lower surface of the hat, the distance between the first magnetic attraction piece and the second magnetic attraction piece is short, the magnetic attraction acting force is large, the attractiveness of the hat is affected by the exposed first magnetic attraction piece, and the protruding first magnetic attraction piece is easy to rust. Meanwhile, the fixing mode of the cap connecting piece and the cap peak is also required to be considered.

In some technical solutions, the first magnetic attraction pieces are magnetic blocks, and the first magnetic attraction pieces are distributed on both sides of a central line of the visor (i.e., a bilateral symmetry axis of the visor) and a central line of the visor. Compare with the magnetic stripe (being bar magnet) of equal width and thickness, the magnetic attraction of magnetic block is less, but if the installation magnetic stripe, then when needs installation face guard, because the magnetic stripe does not have the selectivity to the absorption of piece is inhaled to the second magnetism, the face guard from any position all can be adsorbed by first absorption accessory (magnetic stripe), just also can't realize locate function.

Similarly, in some embodiments, the second magnetic element is a magnetic block.

In some embodiments, the first magnetic attraction members are disposed on both sides of the centerline of the visor and the centerline of the visor. This allows the visor to be stressed evenly. Likewise, in some embodiments, the second magnetic attachment is disposed on both sides of the centerline of the cap bill and the centerline of the cap bill when the mask is installed on the cap bill.

In some technical schemes, the number of the first magnetic suction pieces is the same as that of the second magnetic suction pieces, and the installation positions of the first magnetic suction pieces and the second magnetic suction pieces are up-down corresponding.

In some technical schemes, the number of the magnetic blocks is 2-5. The magnetic blocks are respectively distributed on the central line and two sides of the central line, most areas have no magnetic attraction force, a wearer takes up the mask after wearing the hat and gets close to the visor, the mask can be adsorbed by the magnetic attraction force at the moment, and the second magnetic attraction piece on the mask is easily adsorbed by the first magnetic attraction piece on the visor, so that automatic positioning is realized. The number of the magnetic blocks is more preferably 3, and the automatic positioning function is optimal after tests.

In some technical solutions, the surface layers (upper and lower surfaces) of the visor are made of cotton material (or other material), a core layer is arranged in the surface layers, usually made of plastic, and then the core layer and the surface layers are sewn. The core layer is often made of High Density Polyethylene (HDPE) due to its good thermoformability.

In some technical schemes, the visor comprises surface layers positioned on the upper surface and the lower surface and a core layer positioned between the upper surface and the lower surface, the first magnetic attraction piece is fixed in the core layer, and a waterproof film layer is arranged between the core layer and the surface layers. Because the magnet is easy to corrode, if the magnet arranged in the hat is corroded seriously, the attraction force of the first magnetic part can be reduced, and the connection between the mask and the hat is not firm. Meanwhile, the rust becomes more serious after being washed by water. The rusty spots exude to yellow the hat, the beauty is affected, and the wearing experience is rapidly reduced.

Generally, after the first magnetic member is installed in the first installation hole, a layer of glue (preferably single-sided glue) is adhered to the surface of the first installation hole, so that the first magnetic member can be temporarily fixed for manufacturing in the next process. The first magnetism is inhaled all around and the top of piece and is plastics (first mounting hole is not the through-hole) this moment, and only the lower surface of first magnetism is inhaled the piece and is contacted air and moisture easily, has great corrosion risk. It is very necessary to make waterproof on the lower surface of the first magnetic attraction piece. When first mounting hole is the through-hole, the upper and lower surface of first magnetism piece all need set up the waterproof layer.

The waterproof rete can be set up at the lower surface of first magnetism piece of inhaling, and waterproof rete is located first magnetism and inhales between the piece and the surface course promptly. The waterproof membrane layer can be a hot melt adhesive layer, and the surface layer and the core layer can be firmly bonded after being heated.

In some technical schemes, a hot melt adhesive layer is arranged between the surface layer and the core layer in an area where the first magnetic attraction piece is arranged, and the surface layer and the core layer can be sewn in the area where the first magnetic attraction piece is not arranged. Therefore, the surface layer and the core layer can be prevented from being not tightly attached, and the generation of empty bulge of the cap peak can be prevented.

In some technical schemes, the waterproof film layer adopts a hot melt adhesive layer, and the surface layer and the core layer are bonded through the hot melt adhesive layer. This eliminates the need for any stitching. The surface layer may be pre-stitched for aesthetic purposes, but it does not serve as a stitching function.

In some technical schemes, the waterproof membrane layer adopts a single-sided adhesive and a hot melt adhesive layer. Firstly, sealing a first mounting hole (a first magnetic part is mounted in the hole) by using adhesive tape or adhesive tape with single-sided adhesive; and sealing the hot melt adhesive layer. The double-layer sealing realizes better waterproof effect. The single-sided adhesive can be PET (polyethylene terephthalate) single-sided adhesive.

Therefore, in some technical solutions, the cap bill of the present invention has a structure of: the magnetic attraction piece comprises surface layers positioned on the upper surface and the lower surface and a core layer positioned between the upper surface and the lower surface, wherein a first mounting hole is formed in the core layer, and a first magnetic attraction piece is embedded into the first mounting hole; sealing the first mounting hole through an adhesive tape; and a hot melt adhesive layer is arranged between the surface layer and the core layer.

Preferably, a first mounting hole is formed in the cap peak for mounting the first magnetic piece.

Preferably, a second mounting hole is formed in the mask connecting piece and used for mounting the second magnetic piece.

The preparation method of the protective cover comprises the following steps: the cap, the mask body and the mask connecting piece are prepared respectively, then the mask body is fixed on the mask connecting piece to obtain the mask, and then the mask is arranged below the visor of the cap in a magnetic attraction mode.

In some technical schemes, the mask connecting piece is prepared in an injection molding mode, and the second magnetic part is embedded into the second mounting hole. At the moment, a second mounting hole does not need to be formed in advance, the second magnetic part is fixed in the injection mold in advance, after injection molding is carried out, the second magnetic part is embedded into the mask connecting piece, and the hole position where the second magnetic part is located is the second mounting hole.

The upper surface of the second magnetic part can be directly contacted with the lower surface of the visor, and the magnetic attraction force can be ensured to be maximum at the moment. The side of piece is inhaled to the second magnetism is equipped with the recess, through injection moulding, and the plastics of face guard connecting piece can get into the recess when melting, and the back is inhaled to plastics, inhales the recess play of piece at the second and will form the arch, inhales the piece firmly with the second and fix in the second mounting hole. And if the second magnetic part is fixed in the second mounting hole through glue, when the mask (the mask body and the mask connecting part) is taken down, the second magnetic part is likely to fall off from the second mounting hole.

The injection molding temperature is higher and reaches 200 ℃ or even 240 ℃, and the second magnetic part is easy to demagnetize during molding.

In some technical schemes, a connecting column is arranged on the mask connecting piece, a connecting hole is arranged at the upper part of the mask body, and the connecting column penetrates through the connecting hole to enable the mask body to be fixed on the mask connecting piece.

When the mask is used, the mask can be close to the visor by one hand, so that the mask is automatically adsorbed; when the mask is not used, the mask can be taken down by directly pulling downwards with force. Therefore, the binding force between the mask and the mask connecting piece should be greater than the magnetic attraction force between the first magnetic attraction piece and the second magnetic attraction piece, so as to avoid only tearing the mask off, and the mask connecting piece is still attracted. Therefore, the connecting column and the connecting hole of the invention need to be stressed.

Because the connecting holes are stressed, the connecting holes are prevented from being too close to the upper edge of the mask body and 2mm-10mm, preferably 3-8mm, for example 4mm, 5mm and 6mm away from the upper edge of the mask body. This is related to the material and thickness of the mask.

In some technical schemes, 2-5 connecting columns are arranged. The connecting columns are preferably 3-4, and are also distributed in the middle and on both sides of the mask connecting piece. The height of the connecting column is generally set to 4-8 mm.

In order to enable the mask body to be attached to the face of a human body, the vertical direction of the mask body is vertical, and the left direction and the right direction of the mask body are set to be curved and have a certain radian. In some embodiments, the mask is transparent and flexible. The mask body is typically a layer of poly (ethylene terephthalate-1, 4-cyclohexadienedimethylene terephthalate) film (PETG film for short).

The flat PETG film is arranged on the mask connecting piece, and the curved mask which is attached to the face can be formed. Therefore, the mask connecting member needs to be designed to be curved so as to be attached to the face after the mask body is installed. Typically, the medial portion of the mask attachment member is relatively flat to fit the wearer's forehead and the sides of the mask attachment member are curved rearwardly (relative to the front, rear, left and right sides of the wearer after normal wear) to protect the sides and ears of the wearer.

In some embodiments, the side edges and lower edges of the mask body are free of frames or supports. Because the magnetic attraction effect of the upper edge can firmly fix the mask, frames or supporting pieces do not need to be arranged in other areas, and the sight of a wearer cannot be influenced.

In some technical schemes, the face guard includes the face guard body and is located the face guard connecting piece of the upper border of face guard body, and the piece is inhaled to the top surface installation (the preferred mounting means of embedding) second magnetism of face guard connecting piece, inhales the magnetic attraction between the piece through first magnetism and the second and fixes the face guard in the below of visor.

In some technical schemes, the face mask connecting piece is provided with a connecting column and a mounting groove, the connecting column is positioned on the side wall of the mounting groove, the top of the face mask body is provided with a connecting hole, the upper edge of the face mask body is mounted in the mounting groove, and the connecting column penetrates through the connecting hole to fix the face mask body on the face mask connecting piece.

In some technical schemes, the lateral walls of the two sides of the mounting groove are respectively a first guide plate and a second guide plate, and the connecting column is located on the first guide plate.

In some embodiments, the mask body may be colored, translucent, or opaque, or may be designed to have some protective function (e.g., uv-absorbing) as desired.

In some embodiments, the mask attachment member is designed as a hollow structure. This reduces the weight of the mask attachment. If the mask body and the mask connecting piece are too heavy, a large pulling force can be formed at the visor of the wearer, and the comfort level of the wearer is reduced.

In the present invention, it should be noted that the directional terms such as front, back, left, right, side, etc. are described in terms of the direction of the wearer after the hat is worn by the wearer in a correct manner.

It should be noted that, in the present invention, the "visor" is substantially the same as the "visor" in the prior art, and refers to the front edge of the cap. The "brim" includes the peripheral edge of the cap, and thus the "brim" includes the "bill" of the present invention.

The height of the mask body of the invention can be designed at will, for example, the lower edge of the mask body can reach the forehead, or the eyes, or the nose, or the mouth, or the chin or even exceed the chin. Can be designed according to different protection requirements.

In some technical schemes, when the mask body is not arranged on the mask connecting piece, the mask body is of a planar membrane structure; the mask body is arranged behind the mask connecting piece and is bent into an arc-shaped sheet structure matched with a human face.

The invention has the beneficial effects that:

1. the cap can be detached and installed by one hand on the premise that a wearer does not take off the cap.

2. The positioning design of cap and face guard can make the face guard have high accuracy when installing, need not inhale the piece with the second magnetism on the face guard and inhale the piece with first magnetism very accurately and align, also can be according to the guide of magnetic attraction, fix a position automatically, and can be adsorbed the visor very accurately.

3. The hot melt adhesive layer arranged in the cap can protect the first magnetic attraction piece from being rusted, and can ensure that the surface layer and the core layer are firmly adhered, so that the cap peak does not generate hollowing; meanwhile, the influence on the sewing of the visor and the sewing efficiency due to the existence of the first magnetic suction piece is avoided.

4. The preparation method of the hat has ingenious conception, provides a practical and efficient production method, ensures the quality of the hat and can keep lower production cost.

For example, "up" is a direction toward the head of the human body, "down" is a direction toward the feet of the human body, "left" is a direction toward the left hand of the human body, "right" is a direction toward the right hand of the human body, "front" is the front of the line of sight of the human body, and "back" is a direction opposite to the direction of the line of sight of the human body. These illustrations are merely for the convenience of describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced devices or elements must be in a particular orientation, constructed and operated in a particular orientation, and are not to be construed as limiting the invention.

Fig. 1 is a schematic view showing a cap 1 and a mask 2, wherein the cap has an outer shape which is not clearly distinguished from a general baseball cap, and the cap includes a cap body 11 and a visor 12.

A mask 2, which may be referred to collectively as a shield, i.e., the combination of the cap 1 and the mask 2, is provided under the visor 12 shown in fig. 1. In the embodiment, the cap 1 and the mask 2 are connected in a magnetic attraction manner. For convenience of use, this connection is referred to only as a magnetic attachment.

In certain embodiments, the first magnetically attractable element 13 within the cap bill 12 is mounted within the cap bill 12. referring to FIG. 2, the perspective of the cap bill 12 is shown directly in FIG. 2 for ease of description (the first magnetically attractable element 13 within the cap bill is not actually visible in the perspective view of FIG. 2).

In some embodiments, the visor 12 includes a surface layer located on the upper and lower surfaces and a core layer located between the upper and lower surfaces, the surface layer is a cotton cloth layer, the core layer is a high density polyethylene layer, a hot melt adhesive layer is further disposed between the cotton cloth layer and the high density polyethylene layer, a first mounting hole is disposed on the lower surface of the high density polyethylene layer, and the first magnetic attraction element 13 is located in the first mounting hole.

In some embodiments, the first magnetic attachment 13 is secured to the lower surface of the cap bill 12, as best seen in the bottom view of the cap bill, FIG. 3. Wherein the first magnetic attraction piece 13 can be adhered to the lower surface of the visor 12. However, this method can cause the first magnetic attraction piece 13 to be easily rusted, and the protruding first magnetic attraction piece 13 also affects the appearance.

As shown in fig. 2 and fig. 3, the first magnetic element 13 is a magnetic block (the shape of the magnetic block is not required, and may be square, circular, oval, etc.). The first magnetic elements 13 are three in number and are distributed in the middle and two sides of the visor, specifically, one magnetic block is located on the center line of the visor (i.e., the left and right symmetry axes of the visor), and the other two magnetic blocks are located on the left and right sides near the left and right edges of the visor.

In some embodiments, the first magnetic element 13 can be installed near the front edge of the cap bill, in the middle of the cap bill, or at the back edge of the cap bill.

In some embodiments, the first magnetic element 13 is an elongated magnet, but this will have some adverse effect on the positioning of the mask.

The mask body 21 shown in fig. 1 is unfolded into a transparent film having a thickness of about 2mm after being sequentially detached from the cap 1 and the mask attachment 22, and the flat film structure can be bent to fit the face of the wearer.

In some embodiments, it is desirable to design the mask attachment 22 as shown in FIG. 4, which requires securing the mask body 21 on the one hand and magnetically attaching the visor 12 on the other hand.

As shown in fig. 4 and 5, a second mounting hole 23 is formed on the upper surface of the mask connecting member 22 for mounting a second magnetic member. The second magnetic suction pieces are the same as the first magnetic suction pieces in number and attract each other. The bottom of the face guard connecting piece 22 is provided with a mounting groove, the upper edge of the face guard body 21 is arranged in the mounting groove, the two side groove walls of the mounting groove are respectively a first guide plate 24 and a second guide plate 25, and the first guide plate 24 and the second guide plate 25 are parallel or basically parallel to the face guard body 21 to be mounted. The first guide plate 24 is provided with a connecting column 26 (the first guide plate 24 is perpendicular to the connecting column 26), the height of the connecting column 26 (the direction perpendicular to the first guide plate 24) is generally set to be 4-8mm, holes are formed in the upper edge of the mask body to form connecting holes matched with the connecting column 26, and therefore the mask body 21 can be fixed on the mask connecting piece 22 through the connecting column 26. To facilitate the installation of the mask body 21, the lower edge of the connecting post 26 is chamfered to have a slope.

The following description will be made of a method for manufacturing a cap and a mask according to an embodiment: firstly, forming 3 holes (namely first mounting holes) with the size slightly larger than that of a first magnetic part on a core layer of a visor, and embedding the 3 first magnetic parts into the first mounting holes; the PET single-sided adhesive is sealed at the first mounting hole, and the magnet can be prevented from falling off in the process of entering the next working procedure; coating hot melt adhesive on one surface of the two surface layers in advance, sewing the two surface layers which are pre-coated with the hot melt adhesive, and leaving one side of the surface layers to be not sewn for filling the core layer; and (3) putting the core layer provided with the first magnetic part into the surface layer, sewing the core layer with the cap body, heating to about 150 ℃ after sewing to melt the hot melt adhesive, and firmly bonding the core layer and the surface layer.

Because the surface of the first magnetic part of the cap is not only pasted with PET single-sided adhesive; and a layer of hot melt adhesive is also arranged, and the two layers of materials have waterproof effects, so that the first magnetic suction piece of the cap does not worry about contact with moisture. According to the invention, the prepared cap sample is put into a washing machine for washing, and water cannot enter the first mounting hole; the sample was washed with water 20 times, and the first magnetic attraction member was not found to be corroded.

The first magnetic part uses a high-temperature-resistant magnet, for example, the magnet can resist 120 ℃, the heating time required for melting the hot melt adhesive is short (generally dozens of seconds), the magnetism of the high-temperature-resistant magnet is not seriously influenced by the high temperature in a short time, and meanwhile, the high-temperature-resistant magnet can be directly used when the price of the high-temperature-resistant magnet is not high.

The mask connecting piece can adopt a common process of melting and post-forming (generally called injection molding), and the structure of some mask connecting pieces is not convenient to form due to the hollow design, and certain problems exist in the flowing aspect of common plastics, so that the mask connecting piece can be produced by adopting a 3D printing technology. And a second magnetic piece is arranged on a second connecting hole reserved in the mask connecting piece, and PET single-sided adhesive is pasted for fixing.

When the face guard connecting piece adopts injection moulding, because the temperature of moulding plastics is higher, and the holding time of high temperature is longer, it is great to inhale the magnetism influence of piece to the second, and to the protection casing, the price of ultra-high temperature magnet (for example temperature resistant 200 ℃) can be very expensive, consequently, can use earlier to take not magnetic second to inhale the piece and mould plastics, inhale the piece to the second again and magnetize after waiting to form.

The upper edge of the mask body is fixed on the mask connecting piece, and the mask can be assembled; then the protective cover is absorbed on the visor, and the installation of the protective cover can be completed. When the mask is not used, the mask can be taken down by directly pulling downwards with force. When the mask is used again, the mask is directly adsorbed on the visor.
