[0033] The present application will be further described below in conjunction with the accompanying drawings.

[0034] The present application will be further described below in conjunction with the accompanying drawings.

[0035] Example 1, as Figures 1-7As shown, a one-piece foaming magnetic health care pillow, comprising a one-piece foaming pillow base 1, which is basically foamed material formed by foaming process, a plurality of magnetic particles 2 are hidden in the inside of the pillow base 1, the magnetic particles in the application are invisible or basically invisible, which are hidden and arranged in the inside of the pillow base, further, the inside of the pillow base 1 is further provided with an upper flexible limiting structure which is limited on the upper side of the magnetic particle 2 and has a deformation ability, the inside of the pillow base 1 is further provided with a lower flexible limiting structure which is limited on the lower side of the magnetic particle 2 and has a deformation ability, the magnetic particle 2 is clamped and abuts between the upper flexible limiting structure and the lower flexible limiting structure and is suspended in the upper surface part of the pillow base 1, a sandwich structure is formed between the magnetic particle 2, the upper flexible limiting structure and the lower flexible limiting structure, which is suspended in the part close to the upper surface of the pillow base 1, and it is also necessary in the upper half of the pillow base, the main purpose is to ensure that the position of the magnetic particle is close to the pillow surface, which is generally controlled within 60%~95% of the height of the pillow, for example, the center of the magnetic particle 2 can be selected at about 12cm of the height of the pillow base for a 15cm high pillow base, why is the center of the magnetic particle 2 mentioned here, because the magnetic particle 2 itself has a thickness of about 5mm, so the upper and lower centers thereof are taken as the base point, the pillow base 1 is formed with a first positioning air temporary storage hole k1 on the part corresponding to the magnetic particle 2 and located above each magnetic particle 2, which extends from the upper surface of the part to the upper surface of the magnetic particle 2 and reaches the upper flexible limiting structure, that is, the first positioning air temporary storage hole k1 is arranged on the part of the pillow base between the upper surface of the magnetic particle 2 and the upper surface of the pillow base, the first positioning air temporary storage hole k1 extends from the upper surface of the pillow base to the upper surface of the upper flexible limiting structure, here, the first positioning air temporary storage hole k1 and the magnetic particle 2 are separated by the upper flexible limiting structure, but the bottom end of the first positioning air temporary storage hole k1 is just above the magnetic particle 2, that is, the first positioning air temporary storage hole k1 is in the area above the magnetic particle 2, if the first positioning air temporary storage hole k1 is upright, the whole first positioning air temporary storage hole k1 is in the area above the magnetic particle 2, that is, the vertical projection of the first positioning air temporary storage hole k1 is completely in the vertical projection of the corresponding magnetic particle 2, although one magnetic particle can correspond to two or more first positioning air temporary storage holes k1, but this embodiment recommends using only one first positioning air temporary storage hole k1, one first positioning air temporary storage hole k1 corresponds to the upper of each magnetic particle 2, which is better controllable and more accurate in positioning, and the structure of the pillow base 1 is less damaged, and the first positioning air temporary storage hole k1 is preferably located in the central position above the magnetic particle 2,The comparison is suitable for the first positioning air temporary storage hole k1 in the upright shape, or at least the lower end of the single first positioning air temporary storage hole k1 is in the central position directly above the magnetic particles 2, that is, the lower end of the first positioning air temporary storage hole k1 is used for positioning the magnetic particles 2, which are preferably in the shape of a round cake or a rectangle, so that the axis can be easily and effectively positioned with the axis of the lower end of the first positioning air temporary storage hole k1. Therefore, the first positioning air temporary storage hole k1 is also preferably in the regular hole structure in the upright shape. In fact, our core is that the lower end of the first positioning air temporary storage hole k1 is very suitable for the positioning of the magnetic particles 2 as a positioning point. Simply put, one magnetic particle 2 corresponds to one first positioning air temporary storage hole k1, the first positioning air temporary storage hole k1 is in the middle above the magnetic particles 2, and the two are separated by the upper flexible limiting structure. In addition, the horizontal size of the first positioning air temporary storage hole k1 should be as small as possible, the magnetic particles are placed in a flat manner, and the horizontal size of the magnetic particles 2, that is, the projection size in the vertical direction, is generally about 1 square centimeter. Therefore, the average size of the horizontal cross section of the first positioning air temporary storage hole k1 is controlled to be within 0.25 square centimeters, and the horizontal cross section size of the part exposed on the surface of the pillow should be small, while the horizontal cross section size of the part close to the upper flexible limiting structure should be larger. In this way, the surface part reduces the damage of the structure opening, ensures the aesthetic degree and structural strength, and is not easy to tear and damage. In general, the horizontal cross section size of the upper part of the first positioning air temporary storage hole k1 should be as small as possible, and is preferably within 0.1 square centimeter. The specific position of this upper part can be the horizontal cross section size of a section of at least 5 millimeters long from the top of the first positioning air temporary storage hole k1, that is, the average size of the horizontal cross section of the part of at least 5 millimeters long closest to the top of the first positioning air temporary storage hole k1. If it is a cylindrical shape, it is preferably controlled to be within 0.1 square centimeter. Further, it can be controlled to be about 0.05 square centimeter and as large as possible 0.01 square centimeter. Because the first positioning air temporary storage hole k1 also has the function of temporarily storing air, it has the function of buffering. Since the foaming material is also permeable and has a large porosity, but the porosity itself is micron level, the amount of air that can be stored is relatively small. However, the size of the first positioning air temporary storage hole k1 is at least centimeter level, and the average size of the horizontal cross section is generally more than 1 square millimeter. Therefore, in the unused state, that is, the state of the pillow body not being compressed, the first positioning air temporary storage hole k1 can contain more air, and the lower side of the first positioning air temporary storage hole k1 is blocked by the magnetic particles. When the user leans on the pillow body through the head or other parts, it is against the upper side of the first positioning air temporary storage hole k1, which blocks the upper side of the first positioning air temporary storage hole k1. Therefore, the air stored in the place needs to have a process of being discharged to the horizontal surroundings through the porosity, which can play a good buffering effect.More comfortable and reliable. It should be noted here that the pillow base 1 is a structure similar to a rectangular body, the upper surface will have a slight curvature, as the main leaning surface needs to be slightly flat, here the middle of the front and rear leaning area is slightly concave, the front and rear side is slightly convex, in the unused state, the fluctuation is controlled within 1cm, and the middle is also the main area for head leaning, then the position of the pillow periphery is a circular arc transition structure, which can refer to the existing pillow shape. Therefore, the shape can refer to various shape design styles of existing pillows, but the number of magnetic particles inside needs to be sufficient, and the area covered should be more than 50% of the horizontal plane of the upper part of the pillow base 1, that is, as much as possible to lay and arrange in the horizontal direction. Of course, the magnetic particles are separated, and in addition, they are arranged as much as possible in the area extending from the center of the pillow to the periphery, and the left and right extensions are as full as possible, because the pillow is relatively long in the left and right directions, the user may move the head or multiple users use it, and the magnetic particles in the front and rear direction can be arranged as much as possible in the middle of the front and rear leaning area, because the head and neck are generally leaned in the middle, and the magnetic particles mainly act on the head and neck.

[0036] The special structure design, the flexible limit of the upper and lower sides makes the magnetic particles not easy to flip and move, and compared with the prior art, the structure of the gel is reduced. In the use state, after the upper surface part of the pillow body is compressed, the position of the upper surface of the magnetic particles can be closer to the human body, and the magnetic function effect is more obvious. At the same time, the first positioning air temporary storage hole k1 can not only be used for positioning, but also have a better buffering effect. Moreover, compared with the existing pillow surface slot magnetic structure, the structural integrity is better, and the process is simpler. In the foaming process, the magnetic particles can be directly suspended in the pillow body, and the position of the magnetic particles is not easy to change. The wrapping is also better, and the comfort of use is also better. When the user leans on the part of the pillow where the magnetic particles are located, there is a buffering and adapting process with the support of the pillow body and the temporary support of the air temporary storage of the first positioning air temporary storage hole k1, which has a certain protective effect on the human body and the magnetic installation structure itself, reducing the damage caused by instantaneous impact. Moreover, the aforementioned sandwiched magnetic particle installation structure also serves as a magnetic connection suspension structure, which has better stability and can maintain a good use state in a repeated extrusion and leaning state. The entire structure is more concise, does not use gel and glue, can support water immersion cleaning, and can maintain the stability of the structure. The specific implementation of the above scheme is as follows: in the original state, the pillow body 1 is located on the upper part of each magnetic particle 2 and the corresponding part of the upper and lower magnetic particle 2, and the thickness is not more than 5 cm, that is, in the unused state, the pillow of foaming material is not compressed, at this time, the thickness is the thickest, at this time, the thickness of the part of the pillow body 1 above the upper surface of the magnetic particle 2 is preferably not more than 5 cm, and the thickness of about 2 cm is generally recommended, which is easy to achieve with the existing foaming material, that is, in the unused state or under stress and extrusion, the distance between the magnetic particle and the upper surface of the pillow is controlled to ensure that the magnetic particle is not too close to the surface in the unused state, but can be very close to the human body in use. In the use state, the minimum thickness of the part of the pillow body 1 above each magnetic particle 2 and corresponding to the upper and lower magnetic particle 2 after leaning compression is not more than 10 mm, and further, it is recommended to be about 4 mm. In this way, the magnetic field of the surface of the magnetic particle can greatly exert its effect on the human body, and the comfort is also good, and the human body leaning is more comfortable, which can be selected according to the type and density of the material to ensure that the size requirement is met, that is, in the unused state, the thickness of the part of the pillow body 1 above the magnetic particle is about 2 cm, and in the use state, it is about 4 mm. Of course, this is a recommended size, which can also be selected according to the characteristics of the actual user, the use environment, the material, etc.

[0037] In addition, the aforementioned also mentioned that the size of the first positioning air temporary storage hole k1 is preferably much smaller than the size of the magnetic particles 2, which mainly refers to the horizontal transverse size, that is, the size of the horizontal cross section of the first positioning air temporary storage hole k1 is smaller than the horizontal size of the magnetic particles 2, which can also be understood as the first positioning air temporary storage hole k1 is thin.

[0038] Further, at least one section of the first positioning air temporary storage hole k1 is a tapered section with a diameter gradually increasing from top to bottom, so that the size of the hole is smaller at the top, which provides protection for the pillow itself and the user, and here the first positioning air temporary storage hole k1 can be a tapered hole with a small top and a large bottom, or a certain section of which is a tapered section, and the aforementioned refers to the diameter, that is, the horizontal cross section is a circular tapered section, which is actually a circular truncated cone section, of course, it can also be a rectangular tapered section with a rectangular horizontal cross section, in summary, at least one section of the first positioning air temporary storage hole k1 is a tapered section with a horizontal cross section gradually increasing from top to bottom, and the purpose of this is to make the surface hole part relatively small, to ensure the integrity of the surface structure of the pillow, but also to position the magnetic particles in the production process. Of course, if it is not a tapered hole, a cylindrical section can be formed on the upper side of the tapered section of the first positioning air temporary storage hole k1 and connected to the lower side to form a cylindrical section, the purpose is to have a change in the size of the horizontal cross section between the upper and lower sides, and the size gradually increases from top to bottom. The first positioning air temporary storage hole k1 is in the area directly above the magnetic particles 2, which plays a role in positioning and air temporary storage, and also facilitates cleaning.

[0039] Further, the inside of the pillow base 1 is also provided with a magnetic strip 3 extending left and right, which adopts the existing long rectangular structure and is in a flat shape, and is in contact with the lower side of the upper flexible limiting structure and suspended in the upper surface part of the pillow base 1. The pillow base 1 is located on the upper part of each magnetic strip 3 and corresponds to the upper and lower parts of the magnetic strip 3, and two or more second positioning air temporary storage holes k2 are formed from the upper surface of the part to the upper surface of the magnetic strip 3 and extend to the upper flexible limiting structure. Here, the magnetic strip 3 usually adopts a flexible magnetic strip, with a length of about 50 cm, a width of about 1.5 cm, and a thickness of about 3 mm, and the overall flexibility is good. The lower side does not recommend using the lower flexible limiting structure, and the magnetic particle size is small, the magnetic property is large, and the hardness is high, so it is easy to turn over, move, etc. The magnetic strip is relatively stable, and the compression deformation of the lower side caused by the pillow base extrusion process can be well integrated and deformed, so it can well adapt to the deformation. The second positioning air temporary storage hole k2 and the first positioning air temporary storage hole k1 have the same effect, but it is set for the magnetic strip 3, and the second positioning air temporary storage hole k2 is in the area directly above the magnetic strip 3. In addition, the difference is that each magnetic strip 3 corresponds to multiple second positioning air temporary storage holes k2, i.e. multiple second positioning air temporary storage holes k2 are arranged left and right on the upper side of the magnetic strip 3, and the second positioning air temporary storage hole k2 is used to position the magnetic strip 3. The shape of the second positioning air temporary storage hole k2 can refer to the first positioning air temporary storage hole k1. For example, the second positioning air temporary storage hole k2 can also be a tapered hole with a diameter gradually increasing from top to bottom, or at least one section of the second positioning air temporary storage hole k2 is a tapered section with a gradually increasing horizontal cross-section from top to bottom, and the multiple second positioning air temporary storage holes k2 corresponding to the upper side of each magnetic strip are arranged left and right.

[0040] And the requirement for the magnetic field is that the upper surface magnetic field strength of the magnetic particles 2 is preferably not less than 2000 Gauss and is more than three times the upper surface magnetic field strength of the magnetic strip 3. The upper surface magnetic field is the magnetic field strength at the upper surface of the magnetic particles and the magnetic strip. The magnetic field strength at the position closest to the upper surface of the magnetic particles and the magnetic strip in the space above the magnetic particles and the magnetic strip is the highest. As the height of the space increases, the magnetic field gradually decreases. Therefore, the closer to the upper surface of the magnetic particles and the magnetic strip, the higher the magnetic field. The upper surface magnetic field strength of the magnetic particles 2 is preferably more than 5000 Gauss. The magnetic field strength can be set to 6000 Gauss or 8000 Gauss. The upper surface magnetic field strength of the magnetic strip can be selected to be 700 Gauss or 800 Gauss. Therefore, the magnetic particles need to be strong magnetic materials that have a strong magnetic field and are effective for the human body. The magnetic strip is mainly used to stretch and support the pillow structure on the front and back sides to ensure a certain strength and also has a certain magnetic health care effect. Similarly, in the original state, the thickness of the pillow base 1 located on the upper part of each magnetic strip 3 and corresponding to the upper and lower parts of the magnetic strip 3 is not more than 5 cm. In the use state, the minimum thickness of the pillow base 1 located on the upper part of each magnetic strip 3 and corresponding to the upper and lower parts of the magnetic strip 3 after compression is not more than 10 mm. The specific size can be referred to the preferred setting of the distance between the upper surface of the magnetic particles and the pillow base, and the magnetic strip 3 and the second positioning air temporary storage hole k2 are also separated by the upper flexible limiting structure.

[0041] The arrangement of the magnetic particles and the magnetic strip is as follows. The magnetic particles 2 are arranged in the interval between the two front and rear magnetic strips 3. The magnetic particles and the magnetic strip are both arranged on the upper part of the pillow base. This arrangement allows the magnetic particles with a strong magnetic field to be in the middle and the magnetic strips with a small magnetic field to be in the front and back, forming a regular magnetic distribution interval. In this embodiment, two magnetic strips are arranged in front of and behind each other, and three rows of magnetic particle queues are arranged between the two magnetic strips. Each row of magnetic particle queues is arranged in multiple magnetic particles. The length of each row of magnetic particle queues and the length of the magnetic strip are controlled to be similar. The interval distance of the five rows formed by the two magnetic strips and the three rows of magnetic particle queues is consistent. This arrangement has good implementation effect. Of course, other arrangements of magnetic materials can also be used. Each magnetic particle queue generally has at least 6 magnetic particles. The total number of magnetic particles is generally more than 20, but not too many. About 30 is appropriate. Alternatively, two magnetic strips can be added to the five rows to form a seven-row structure. The two newly added magnetic strips are respectively arranged on the front side and the rear side of the five-row structure. That is, there are two magnetic strips arranged in front of and behind each other on the front side of the pillow, and there are two magnetic strips arranged in front of and behind each other on the rear side of the pillow.

[0042] Next, the specific implementation of the limiting structure is further described, wherein the upper flexible limiting structure is selected as a continuous soft pad 4 that can cover all magnetic particles 2. The continuous soft pad 4 is a whole continuous pad, that is, each part is continuous with other parts, and the continuous soft pad 4 is preferably in the shape of an approximate rectangle and can cover all magnetic particles 2 on the upper side of all magnetic particles 2. A plurality of upper and lower through foaming flow shaping holes 40 are formed on the continuous soft pad 4. Since the magnetic particles are in a suspended structure, the foaming flow shaping holes 40 can be filled with foaming material in the inverted forming process. Of course, if some foaming flow shaping holes 40 are clamped by magnetic particles or some positioning structures in both directions, it may be more difficult to fill the material. On the one hand, such foaming flow shaping holes 40 are very few, and even if there are some, they have little effect on the structure. On the other hand, even if there are such holes, as long as some positioning grooves or concave-convex structures are formed on the surface of the positioning structure or the magnetic particles to form gaps, the foaming material can still enter such holes and be filled. In this way, the continuous soft pad 4 plays the role of a steel mesh in the foaming forming process of the pillow base, and can better adhere to the foaming material on the upper and lower sides. Moreover, the continuous soft pad 4 can flow the foaming material upward and downward to form due to the presence of the foaming flow shaping holes 40. At the same time, the foaming flow shaping holes 40 can be more completely covered by the magnetic particles 2 on the upper side due to the filling of the foaming material in the foaming flow shaping holes 40. Therefore, the magnetic particles can be completely covered and hidden. Further, the magnetic particles 2 are covered with at least one complete foaming flow shaping hole 40, that is, the horizontal size of the magnetic particles 2 is greater than that of the foaming flow shaping hole 40. This is to ensure that the magnetic particles 2 cannot pass through the foaming flow shaping hole 40. The foaming flow shaping hole 40 can be a regular hole shape such as a square, a rhombus, or a circle, and the area is generally less than half of the upper surface area of the magnetic particles, for example, the area of the foaming flow shaping hole 40 is preferably one-fifth to one-tenth of the upper surface area of the magnetic particles. The continuous soft pad 4 forms an upper connecting muscle network 41 on the periphery of the foaming flow shaping hole 40. The upper connecting muscle network 41 can be understood as the solid part of the peripheral enclosure formed by the foaming flow shaping hole 40, and at least one part of the upper connecting muscle network 41 is in the area enclosed by the bottom of at least one first positioning air temporary storage hole k1. It can be seen that the first positioning air temporary storage hole k1 is separated from the lower side by the upper connecting muscle network 41, so that the first positioning air temporary storage hole k1 and the magnetic particles are respectively on the upper and lower sides of the upper connecting muscle network 41, thereby achieving the various beneficial effects described above. Such a design can make the foaming structure stronger and more stable, and the foaming shaping effect is better, just like the reinforcement of cement, which can better integrate the foaming material together.The continuous soft gasket 4 here is corresponding to all the magnetic particles, that is, one continuous soft gasket 4 covers all the magnetic particles.

[0043] And the preferred design of the lower flexible limiting structure, recommend to adopt different design ideas, specific for the lower flexible limiting structure includes a number of located in the lower side of the magnetic particles 2 abutting discrete setting of the support and reinforcement anti-turn pad 5, that is, the lower flexible limiting structure is composed of a plurality of support and reinforcement anti-turn pad 5, in addition, more important is that the softness of the support and reinforcement anti-turn pad 5 is lower than the softness of the continuous type soft pad 4, the continuous type soft pad 4 is on the upper side, the length is relatively large, and the compression deformation is the first time, and the extrusion deformation shape is relatively large, which needs a larger softness of the following deformation, and the lower part has the compression buffer of the pillow base due to the upper side, and the support and reinforcement anti-turn pad 5 is in the middle and lower thick area of the pillow base, so the support and reinforcement anti-turn pad 5 can be relatively soft. And, further optimized scheme is that each support and reinforcement anti-turn pad 5 is covered with at least one complete magnetic particle 2, here, the vertical projection area of each support and reinforcement anti-turn pad 5 is greater than the vertical projection area of the magnetic particle, for example, the horizontal size of the magnetic particle is understood as the vertical projection area of the magnetic particle, the foregoing is generally 1 square centimeter, and the vertical projection area of the support and reinforcement anti-turn pad 5 is greater than that of the magnetic particle and preferably within two times or four times, because too large effect is not ideal, for example, the horizontal area size of the support and reinforcement anti-turn pad 5 can be selected as 3 square centimeters or 4 square centimeters, further preferably, one magnetic particle is matched with one support and reinforcement anti-turn pad 5, the vertical projection shape of the support and reinforcement anti-turn pad 5 and the vertical projection shape of the magnetic particle can be selected as the same, for example, the vertical projection of the magnetic particle is circular, and the vertical projection of the support and reinforcement anti-turn pad 5 can also be selected as circular, and the magnetic particle is in the central area of the upper surface of the support and reinforcement anti-turn pad 5, and the two shaft centers are consistent, that is, each magnetic particle is attached to the center of the upper surface of the support and reinforcement anti-turn pad 5, and each support and reinforcement anti-turn pad 5 is matched with one magnetic particle. Such design makes the stability of the magnetic particle position further strengthened, and the base itself is not easy to be damaged, and each support and reinforcement anti-turn pad 5 is discrete and spaced from each other, and the spacing between the adjacent two support and reinforcement anti-turn pads 5 is generally controlled to be about 1 centimeter.This structure is similar to the structure of a big tree or a hot air balloon, and the support and reinforcement anti-overturning pad 5 is equivalent to the root system of the tree or the pulling rope around the hot air balloon. Since the support and reinforcement anti-overturning pad 5 is larger than the horizontal size of the magnetic particles and completely covers the magnetic particles on the lower side, and the hardness of the support and reinforcement anti-overturning pad 5 is relatively high, the overall magnetic particles can be effectively prevented from being affected by other magnetic particles and being overturned due to extrusion deformation on the lower side. In addition, the dispersed root system structure can still better adapt to the deformation, extrusion and diffusion on the upper side, because they are dispersed, even if the hardness is high, they can still adapt very well. Here, the hardness of the support and reinforcement anti-overturning pad 5 is greater than that of the continuous soft pad 4. The Shore D hardness of the continuous soft pad 4 can be selected to be between 30-60, and the Shore D hardness of the support and reinforcement anti-overturning pad 5 can be selected to be between 70-90. However, the entire area of the continuous soft pad 4 is about one hundred times the area of the support and reinforcement anti-overturning pad 5, for example, the area of the support and reinforcement anti-overturning pad 5 is 4 square centimeters, and the continuous soft pad 4 can be 1000-2000 square centimeters. Such a structure design is more suitable for this pillow structure.

[0044] As a preferred, the support and reinforcement anti-overturning pad 5 is formed with a plurality of auxiliary connection mesh holes 50, and the support and reinforcement anti-overturning pad 5 is formed with a lower connecting muscle network 51 at the periphery of the auxiliary connection mesh hole 50. The forming structure of the lower foaming material can also be more stable. Here, the support and reinforcement anti-overturning pad 5 is perforated with reference to the continuous soft pad 4 and forms the lower connecting muscle network 51, which is also for the compatibility of the foaming forming structure and will be more firm. The foaming material is attached and formed along the muscle network and the mesh hole and has the structure strength of the meridian and bone. Moreover, similarly, the size of the auxiliary connection mesh hole 50 is smaller than the lower surface area of the magnetic particle. Of course, generally, the upper and lower surfaces of the magnetic particle are basically the same as the design of the foaming flow and shaping hole 40. If there is optimization, the auxiliary connection mesh hole 50 can adopt a diamond hole, and the foaming flow and shaping hole 40 can adopt a hexagonal hole, but the difference between the hole areas of the two should not be too large, and the size should be kept as the same as possible. Because the overall deformation of the continuous soft pad 4 is relatively large, the adaptability of the hexagonal structure is better, and the support and reinforcement anti-overturning pad 5 is a small structure locally, so the structure with less side is relatively stable to ensure the strength. Further, the four sharp corners of the diamond hole of the auxiliary connection mesh hole 50 are directed in the left and right directions and the front and back directions, which are consistent with the direction of the pillow. In this way, the compatibility of the structure is also relatively good.

[0045] Further preferably, the periphery of the continuous soft pad 4 is formed with a plurality of upper periphery transition connecting ribs 42 integrally connected with the upper connecting rib network 41, and the periphery of the support and reinforcement anti-overturning pad 5 is formed with a plurality of lower periphery transition connecting ribs 52 integrally connected with the lower connecting rib network 51. The upper and lower periphery transition connecting ribs 42 and 52 are similar to capillaries or branches on a main road, which are designed to better extend to the foamed material around the periphery, so that the stability of the overall foamed material structure after molding is better, and it is not easy to deform and break, that is, the support and reinforcement anti-overturning pad 5 plays a better role in supporting the roots. Of course, the overall continuous soft pad 4 on the upper side also has such transition connecting ribs 52 on the four peripheries, and the foaming and molding of the pillow body around the four peripheries is more firm.

[0046] In addition, in the above structure, the material selection is recommended as follows: the pillow body 1 is made of foamed sponge or foamed latex, that is, it is foamed and molded by sponge raw materials or latex raw materials. As mentioned above, the support and reinforcement anti-overturning pad 5 has a softness less than that of the continuous soft pad 4, so the support and reinforcement anti-overturning pad 5 can be made of nylon plastic material, and the continuous soft pad 4 can be made of polyester fiber material. Further, the thickness of the support and reinforcement anti-overturning pad 5 is greater than that of the continuous soft pad 4, for example, the thickness of the support and reinforcement anti-overturning pad 5 is 1.5-2 mm. The thickness of the continuous soft pad 4 can be 0.5-1 mm.

[0047] Further, the outer end of the upper periphery transition connecting rib 42 and the lower periphery transition connecting rib 52 is a free end. As mentioned above, the lower periphery transition connecting rib 52 is designed to extend to the foamed material and be connected with the foamed material. It can be seen that one end of the lower periphery transition connecting rib 52 is integrally connected with the lower connecting rib network 51 of the main body of the support and reinforcement anti-overturning pad 5, and the other end is not connected with the lower connecting rib network 51, but is preferably a free end only connected with the foamed material, that is, it can be used as a capillary type tight connection around the pad. The upper periphery transition connecting rib 42 also has the same design idea.

[0048] Through the above design, the magnetic particles can be suspended in the complete pillow base, which can be formed at one time. The magnetic particles not only get better protection, but also can be closer to the human body for use, have better buffering when used, the magnetic field effect is better, the stability of the pillow structure is higher, and the pillow is not easy to be damaged and deformed, etc. The problems of magnetic particle turning and translocation are effectively solved, the problems of the original pillow with gel structure being easy to break and easy to produce odor are greatly improved, and the same magnetic field can be better played in the structure of the application. The whole pillow structure design concept is greatly improved, and a new production process can be formed. The comfort, stability and magnetic function of the pillow can be greatly strengthened, and the structure is simple but not simple. The cost control is also greatly strengthened, including production, later use, after-sales cost, etc.

[0049] Embodiment 2, as shown in the figure, a mold for producing a foamed pillow, this embodiment is specially designed for the pillow in embodiment 1, which can effectively produce the integrated foamed magnetic health care pillow in embodiment 1. Figures 8-16

[0050] Specifically, it includes an upper mold m1 and a lower mold m2 that can be split up and down and opened, the lower mold m2 is formed with a pillow base foaming forming groove m20 in an inverted state for foaming forming to make a pillow base, the inverted state means that the pillow base is inverted for foaming forming, the pillow base is a pillow main body support structure formed by foaming of foaming material, further, it is also a special design point of this embodiment, that is, the lower mold m2 is installed with an inner suspension positioning structure for positioning the suspension embedded built-in structure in the upper part of the groove bottom of the pillow base foaming forming groove m20, the suspension embedded built-in structure is supported by the inner suspension positioning structure and suspended in the air, then in the foaming process, the suspension embedded built-in structure is directly embedded in the pillow base, so that after foaming forming, the suspension embedded built-in structure is suspended and embedded in the foamed pillow base, and the position of the suspension embedded built-in structure in the pillow can be controlled by the left and right front and back position and the length of the upper and lower of the inner suspension positioning structure after the suspension embedded built-in structure is finally formed.

[0051] In one embodiment, the inner suspension positioning structure includes a plurality of upright positioning piles m3, the top of the positioning pile is used to place and position the suspension embedded built-in structure. The part of the positioning pile m3 in the pillow base foaming forming groove m20 is used to form the first positioning air temporary hole k1 or the second positioning air temporary hole k2 in the foaming forming, so these two holes can correspond to the positioning of the suspension embedded built-in structure in the production process, and have good use value after later forming.

[0052] ​As preferred, the positioning pile m3 is a magnetic pile that can be attracted by magnetic objects, and can be positioned and connected to the suspended embedded built-in structure by magnetic attraction. Correspondingly, the suspended embedded built-in structure includes magnetic particles and / or magnetic strips, so that the magnetic particles and the magnetic strips can be temporarily placed and connected to the positioning pile m3 by magnetic attraction, and due to the design of the structure, the demolding is not affected. The magnetic force is relatively easy to separate the positioning pile m3 from the magnetic particles and the magnetic strips. In addition, the positioning pile m3 can be electromagnetic, not permanent magnetic. For example, the external structure of the positioning pile m3 is non-ferromagnetic, such as aluminum, and an electromagnetic coil is arranged in the positioning pile m3. By charging and discharging, the magnetic attraction, repulsion, and separation operations between the magnetic objects or the ferromagnetic suspended embedded built-in structure can be performed.

[0053] The first positioning air temporary storage hole k1 corresponds to the positioning pile m3 of the magnetic particle, and the second positioning air temporary storage hole k2 corresponds to the positioning pile m3 of the magnetic strip. According to the size and arrangement of embodiment 1, each first positioning air temporary storage hole k1 and each second positioning air temporary storage hole k2 represent the position of each positioning pile m3. Therefore, it is preferred that one positioning pile m3 positions one magnetic particle, and multiple positioning piles m3 position one magnetic strip. Correspondingly, three rows of positioning pile m3 queues are arranged in the middle region of the pillow base foaming forming groove m20, each row of positioning pile m3 queues has a plurality of left and right spaced positioning piles m3, and the number and position of the positioning piles m3 in the three rows of positioning pile m3 queues correspond to the number and position of the magnetic particles. The center of the magnetic particle is generally arranged opposite to the center of the top of the corresponding positioning pile m3. Then, one more row of positioning pile m3 queues is arranged on the front side and the rear side of the three rows of positioning piles m3 in the middle region, respectively. The front and rear sides of the one row of positioning pile m3 queues are used for positioning the front and rear magnetic strips, respectively. Each of the two positioning pile m3 queues has more than three left and right spaced positioning piles m3, and the positioning piles m3 in each of the two queues support and position one magnetic strip on the lower side. Preferably, there are at least three positioning piles m3, which are respectively below the left end, the right end, and the middle of one magnetic strip. Here, the magnetic strip also needs to be placed upside down on the positioning pile m3 in the pillow forming process. If the structure of the seven rows of magnetic bodies as described above is used, two more rows of positioning pile m3 queues are needed, one on the most front side and one on the most rear side, which are used for the other two magnetic strips.

[0054] Further, the positioning pile m3 is detachably connected to the lower mold m2 at the groove bottom of the pillow base body foaming forming groove m20, facilitating replacement and maintenance. The detachable mode can adopt the following scheme: the lower part of the outer periphery of the positioning pile m3 is formed with external threads, and the groove bottom of the pillow base body foaming forming groove m20 is provided with a bottom thread hole for screwing and disassembling the lower part of the positioning pile m3. This design allows the positioning pile m3 to be threadedly connected to the bottom thread hole, facilitating disassembly. Of course, it can also be in the form of magnetic attraction, adsorbed at the groove bottom of the pillow base body foaming forming groove m20, but the suction force here needs to be larger, and the positioning pile m3 cannot be pulled out during demolding. Of course, the positioning pile m3 can also be fixed on the groove bottom of the pillow base body foaming forming groove m20 by welding and other existing processes, which can also be used, but the flexibility is a little worse, and the detachable fixing connection mode is still recommended.

[0055] As a preferred, the positioning pile m3 is a pile structure with telescopic length up and down. The advantage of this structure is that as the foaming raw material is injected, the positioning pile m3 with the suspended embedded built-in structure will sink, which can compress the foaming raw material that first enters the pillow base body foaming forming groove m20. Because the foaming raw material that first enters has begun to foam and form, the foaming agent has begun to react to produce gas. Then, due to the gravity of the floating embedded built-in structure and the upper part of the positioning pile m3 and the pressure of the liquid foaming raw material, the gas will go up, and the density of the foaming raw material at the lower side of the pillow base body foaming forming groove m20 can be higher, and the strength of the structure of the finally formed pillow surface part can be better, which can better protect the magnetic material.

[0056] The telescopic pile structure of the positioning pile m3 can further adopt the following embodiments. The positioning pile m3 comprises a support section m31, a telescopic section m32 and a mounting section m33 connected in sequence from top to bottom. The upper part of the support section m31 is used for positioning and embedding the built-in structure. If the structure is a magnetic particle or a magnet, the support section m31 itself can be magnetic, that is, the support section m31 is a ferromagnetic body or externally non-ferromagnetic and internally provided with an existing electromagnetic device, so as to attract and position the magnetic material. The telescopic section m32 is fixed to the lower side of the support section m31 in the existing manner. The telescopic section m32 can be an elastic telescopic structure, for example, an upright spring or a damping air rod. If it is a spring, the upper and lower ends of the spring are fixed to the lower part of the support section m31 and the upper part of the mounting section m33 respectively by welding or other existing fixing methods. If it is a damping air rod, the damping air rod is placed upright, the piston rod is at the upper end and the cylinder is at the lower end. The upper end of the piston rod is fixed to the lower part of the support section m31, and the lower end of the cylinder is fixed to the upper part of the mounting section m33. The fixing method can be the existing one. Of course, it is also feasible to connect the damping air rod upside down to the support section m31 and the mounting section m33. The mounting section m33 serves as a base and is used for mounting, fixing and connecting with the lower mold m2 or can be movably connected. This design enables the positioning pile m3 to realize the telescopic function. The horizontal cross-sectional size of the magnetic particle and the magnetic strip can be greater than that of the support section m31, so as to realize the pressing of the raw material and make the upper part of the pillow more compact after forming.

[0057] Further, at least a part of the positioning pile m3 above the groove bottom surface of the pillow base foaming forming groove m20 is in an inverted conical shape. In Embodiment 1, the first positioning air temporary storage hole k1 and the second positioning air temporary storage hole k2 are mentioned. One of the functions of the positioning pile m3 is to form the first positioning air temporary storage hole k1 and the second positioning air temporary storage hole k2 during foaming. The part of the positioning pile m3 located in the pillow base foaming forming groove m20 forms the first positioning air temporary storage hole k1 and the second positioning air temporary storage hole k2. However, since the forming process is inverted, it is appropriate to design the shape of the upper part of the positioning pile m3 as an inverted conical shape, that is, the size of the horizontal cross section is large at the top and small at the bottom. This will also have a downward pressing effect. This part can be on the support section m31, that is, at least a part of the support section m31 is in an inverted conical shape. The whole can be conical, or part of it can be conical and the other part can be cylindrical. For example, the support section m31 is fixedly connected by a conical upper support section m311 and a cylindrical lower support section m312. This is beneficial to the formation of the first and second positioning air temporary storage holes and can also be used to press the foaming raw material.

[0058] Further optimization, positioning pile m3 set pressure sensor, for example, in the telescopic section m32 can be set pressure sensor, because of the detection of positioning pile m3 arrangement put in the embedded structure after the suspension and in the foaming raw materials into the forming process of the pressure, according to the detection of pressure to control the position and flow of raw material injection. And support section m31 can be configured temperature sensor, by detecting the temperature of foaming raw materials forming, to control the injection of raw materials and temperature control mechanism of temperature control of the molding process. In addition, the displacement sensor can also be set in the positioning pile m3, which can be used to detect the telescopic degree of the positioning pile m3, or in other words, to detect the height position of the magnetic particles or magnetic strips, because the telescopic process will be different, the general production demand is to keep consistent as much as possible, of course, sometimes according to the needs of different height control, but this difference is controllable. Here, if the telescopic section m32 is a spring, then this is a passive telescopic structure, which is completely passive and naturally telescopic under the pressure from above, so there will be some lack of precision control, then the installation section m33 can be designed to move up and down, for example, the bottom of the installation section m33 is connected with an existing lifting mechanism s, such as automatic control of the screw structure or air cylinder structure, which can also be a linear motor, as long as it can make the installation section m33 move up and down actively. If the telescopic section m32 is a damping air cylinder, the damping air cylinder can be electrically controlled, that is, it can be automatically controlled, so that passive and active telescopic switching can be realized. There are many existing ones, which can be controlled by electromagnetic valve, such as passive compression at the beginning of the feeding stage, according to the pressure detection, the pressure is unified as a reference to control the injection position and flow of raw materials, and then after the raw material injection, the active telescopic is adjusted to control the height position of each magnetic particle or magnetic strip to the predetermined position; of course, the position of the displacement sensor can also be detected, and then the pressure of the positioning pile m3 in different positions can be used to control the injection position and flow of raw materials, but in this case, it is better to set a pressure sensor in the support section m31, which mainly detects the hydraulic pressure of the raw materials and the gravity of the suspension structure. Because the damping air cylinder is in active telescopic, only the internal damping force can be measured. In order to achieve consistency of position, etc., some areas need more active pressure due to the flow of raw materials, so the pressure detection of multiple positions can provide a more comprehensive understanding of the internal pressure situation.

[0059] Of course, in order to better achieve installation, the lower die m2 is provided with an assembly slot hole m200 extending upward and downward for inserting the positioning pile m3 for assembly. The assembly slot hole m200 is provided in a part below the groove bottom of the pillow base body foaming groove m20 of the lower die m2, which can be a through hole extending upward and downward. In this way, the positioning pile m3 can be conveniently inserted upward and downward for installation or movement, etc. If the above structure is adopted, the installation section m33 and the telescopic section m32 are generally recommended to be cylindrical and have a horizontal cross section with a size larger than that of the support section m31. Therefore, the lower part of the assembly slot hole m200 is used for installing and connecting the installation section m33. The size of the lower part of the assembly slot hole m200 is correspondingly larger. If the installation section m33 is fixed and does not need to be lifted, a thread can be provided on the periphery of the installation section m33 for direct installation and connection in the lower part of the assembly slot hole m200. The lower part of the assembly slot hole m200 is formed with a corresponding thread. In this way, the installation section m33 can be connected through the thread. Of course, the existing pin shaft structure or other existing module installation assembly structure can also be used for installation and connection. As long as the installation section m33 is installed in the lower part of the assembly slot hole m200, if the bottom of the installation section m33 is connected to the lifting mechanism s, the lifting mechanism s is installed and connected with the lower part of the assembly slot hole m200, and the installation and connection mode adopts the existing fixed mode. The telescopic section m32 can smoothly extend and contract in the middle part of the assembly slot hole m200. Therefore, the size of the assembly slot hole m200 in this part can also be slightly larger.But the assembly slot hole m200 upper part through the part of the support section m31 requires higher, because on the one hand, the support section m31 can be lifted, on the other hand, the raw materials are required to try not to leak down into the assembly slot hole m200, so here the assembly slot hole m200 upper part of the size of the part through the support section m31 can be up and down, try to ensure consistency, except that the assembly slot hole m200 upper part of the inner wall can be embedded in the groove O type sealing ring, to ensure that the support section m31 can move up and down and avoid the raw materials down, here, if the support section m31 is a whole cylinder, the assembly is relatively simple, as long as the size is consistent, and if the support section m31 is fixedly connected by the upper part of the taper support section m311 and the lower part of the cylindrical support section m312, the cylindrical support section m312 is as a moving section that can be lifted with the telescopic section m32, the cylindrical support section m312 is consistent with the size of the upper part of the assembly slot hole m200 and the cylindrical support section m312 is up and down through the upper part of the assembly slot hole m200 and ensures that the cylindrical support section m312 has a part above the groove bottom of the pillow base foaming forming groove m20, the lower end of the cylindrical support section m312 is fixedly connected with the upper end of the telescopic section m32, for example, the lower end of the cylindrical support section m312 is fixedly connected with the upper end of the piston rod of the damping gas rod, the fixed mode can adopt the existing detachable fixing mode such as screw connection, pin connection, key connection, which is appropriate, convenient to disassemble and assemble. Further, the lower end of the taper support section m311 and the upper end of the cylindrical support section m312 are also preferably detachably connected, which is convenient for operation and assembly. The preferred mode is that a screw hole extending upward and downward is formed in the top part of the cylindrical support section m312, a threaded column is integrally connected to the bottom of the taper support section m311, and the threaded column is screwed with the screw hole. Of course, other installation methods can also be used, but this method can ensure better continuity of the structure and look like an integral part without protruding or recessed structure. The top of the taper support section m311 can form a slot or a cross slot for easy operation, and this does not affect the placement and positioning of the magnetic material. Of course, the taper support section m311, the cylindrical support section m312, the telescopic section m32 and the mounting section m33 can have space inside instead of being solid, because sensors, wires and other components can be placed therein. In addition, wire holes can be formed in the bottom of the taper support section m311, the top of the cylindrical support section m312, and the end or side of the telescopic section m32 and the mounting section m33 for wire drawing. Of course, the wires can also be partially routed in the assembly slot hole m200 or in the lower part of the lower die. As long as it does not affect the structure in the pillow base foaming forming groove m20.

[0060] The aforementioned positioning pile m3 is generally separately arranged, and one positioning pile m3 is composed of one supporting section m31, one telescopic section m32 and one mounting section m33. Next, another embodiment of the positioning pile m3 is provided, and the lower parts of the assembly grooves m200 can also be communicated, that is, a communication space t1 capable of communicating the lower parts of the assembly grooves m200 is arranged on the lower die, so that the use of the telescopic section m32 and the mounting section m33 can be reduced, that is, the number of the supporting sections m31 is relatively large, which is reasonably selected according to the number of the magnetic objects, but the number of the telescopic section m32 and the mounting section m33 can be reduced, and a plurality of supporting sections m31 can share one telescopic section m32 and one mounting section m33. The specific implementation is that the bottoms of the plurality of supporting sections m31 are fixedly connected to the upper side of a communication rod t2 which transversely passes through the communication space through the existing mounting mode, and then the lower side of the communication rod t2 is used for being connected and fixed to the telescopic section m32 and the mounting section m33, and the connection mode adopts the existing fixing mode or the mounting mode as described above. This embodiment is very suitable for the case where the control precision requirement is not very high, can reduce a lot of structure and control, and can reduce the production difficulty, and is suitable for the needs of high-end customers.

[0061] As preferred, the mold can be configured with a positioning mold m4, which is transferred and positioned by a mechanical hand clamping delivery or other existing positioning clamping device, of course, manual methods can also be used. The positioning mold m4 forms a magnet positioning hole m40 for the magnetic particles or magnetic strips to be placed and vertically penetrated. The positioning mold m4 can adopt a cuboid template, but the overall size of the template is smaller than the overall size of the pillow base foaming forming groove m20 and can be placed in the pillow base foaming forming groove m20. The lower surface of the positioning mold m4 is used to attach the continuous soft gasket 4. During the production of the pillow, the continuous soft gasket 4 is pre-set at the lower surface of the positioning mold m4. The outer peripheral part of the positioning mold m4 can be connected with some existing clamping mechanism or vacuum suction device, etc. which can tension and release the continuous soft gasket 4. Therefore, the continuous soft gasket 4 is locked on the lower side of the positioning mold m4 by the aforementioned clamping mechanism or vacuum suction device. Then, the magnetic particles and magnetic strips are placed from top to bottom into the corresponding magnet positioning hole m40. The existing infrared or laser positioning structure is set on the mold and the positioning mold m4, so that the positioning mold m4 is accurately moved to the upper side of the positioning pile m3. The continuous soft gasket 4 is attached to the top of the positioning pile m3, and the magnetic particles and magnetic strips are pressed on the upper side of the continuous soft gasket 4 and can be attracted due to magnetic attraction. Then, the clamping mechanism or vacuum suction device is released, and the positioning mold m4 is moved upward, so that the continuous soft gasket 4 and the magnetic particles and magnetic strips are left on the upper side of the positioning pile m3 and placed on the upper side of the positioning pile m3. Of course, the positioning mold can not be used, for example, the magnetic particles and magnetic strips and the continuous soft gasket 4 can be placed directly by manual or other direct positioning automatic devices.

[0062] As preferred, the upper mold m1 and the lower mold m2 are hingedly connected at the rear side, i.e. hingedly connected by a hinge or a hinge structure. The front side of the upper mold m1 and the lower mold m2 is provided with an opening and closing mechanism which can be opened and closed and loose. The opening and closing mechanism can adopt an existing structure, for example, a clamping plate is fixed on the front side of the upper mold m1 and the lower mold m2 respectively, and then the structure of the upper and lower penetrating bolts and the distribution of the nuts is used to open and close. Of course, a power structure such as a pneumatic cylinder can also be used to push the upper mold m1 to open and close. The main function is to open and close.

[0063] As preferred, the lower surface of the lower mold m2 is a flat pressing surface that can close the upper side of the pillow base foaming molding groove m20, which is to ensure that the pillow bottom surface is flat, and the groove bottom surface of the pillow base foaming molding groove m20 does not need to be flat because it is the real surface of the pillow and can have a slightly arc-shaped surface.

[0064] More importantly, the upper side of the upper mold m1 is provided with a temperature control mechanism. The foaming process needs to have good stable control of the temperature to ensure that the product after foaming has higher stability. The temperature control mechanism is preferably a water temperature control mechanism. The temperature control mechanism includes a water pipe m10 integrally connected at the upper surface part of the upper mold m1. The material of the water pipe m10 and the upper mold m1 is the same, which is metal, such as steel or aluminum alloy. The lower mold also adopts the same material. The water pipe m10 includes a front pipe segment m11, a rear pipe segment m12, a left pipe segment m13, and a right pipe segment m14. The left end of the front pipe segment m11 can be in communication with the front end of the left pipe segment m13. The left end of the rear pipe segment m12 can be in communication with the rear end of the left pipe segment m13. The right end of the rear pipe segment m12 can be in communication with the rear end of the right pipe segment m14. The front end of the right pipe segment m14 is close to but slightly separated from the right end of the front pipe segment m11, for example, separated by about 5 cm. In this way, one of the right end of the front pipe segment m11 and the front end of the right pipe segment m14 serves as the water inlet end and the other serves as the water outlet end for external water pipe connection. Of course, other connection methods can also be used, but the important design is that among the four pipe segments, the adjacent two ends of two adjacent pipe segments serve as free ends as water inlet and outlet ends.

[0065] In this way, the overall design of the mold is very suitable for the production of the foaming pillow of embodiment 1. Not only is the setting of the magnets more scientific and reasonable, and the suspension structure is more beneficial to the human body and the structure itself, but also the cost is greatly controlled. Moreover, the mold has better controllability for foaming, better effective control of various conditions for foaming, control of the physical properties of the foaming material itself, higher controllability for production, and suitability for production of pillows of various qualities.

[0066] Embodiment 3, referring to the drawings in Embodiments 1 and 2, a manufacturing process of the integrated foaming magnetic health-care pillow, which is very suitable for producing the pillow in Embodiment 1, the mold in the process can also use the mold in Embodiment 2, and the specific embodiments involved in Embodiments 1 and 2 can also be applied to this embodiment.

[0067] The specific process of this embodiment is as follows: including steps: S1, the mold is opened and a layer of upper flexible limiting structure is suspended and laid in the pillow base foaming forming groove m20 of the mold; S2, a plurality of inverted magnetic particles located at the upper side surface of the upper flexible limiting structure are arranged in the pillow base foaming forming groove m20 of the mold; S3, the mold is closed and foaming material is filled into the pillow base foaming forming groove m20 to form an integrated foaming magnetic health-care pillow; S4, demolding. The upper flexible limiting structure is separated from the pillow base foaming forming groove m20 by a certain distance, so that the upper flexible limiting structure is close to the surface part of the formed pillow, which is consistent with the design idea of the mold, and an inverted pillow is formed to facilitate the smooth implementation of the forming process, including the design of the suspension structure. Of course, the upper flexible limiting structure needs to be supported by the corresponding suspension structure, and the specific embodiments will be provided later. The inverted magnetic particles refer to the front surface of the magnetic particles facing upward, of course, the front and back surfaces of the magnetic particles have different magnetic poles, but the magnetic field strength is the same. However, the periphery of the front surface of the magnetic particles will be provided with a round corner or a chamfer to remove sharp edges, because the front surface of the magnetic particles is closer to the user during use, one is to reduce the discomfort of leaning against the force hitting the edge, and one is to reduce the damage caused by the magnetic particles during the extrusion deformation process on the upper side of the pillow body. The front surface will remove these sharp edges on the periphery, and in this process, it is inverted and formed, so accordingly, the magnetic particles also need to be inverted and placed, that is, the front surface faces downward and abuts against the upper flexible limiting structure, and then after all the magnetic particles are inverted and arranged on the upper side of the upper flexible limiting structure, the foaming material is put in for foaming. The foaming material can use existing sponge foaming raw materials or latex foaming raw materials, etc., which can be selected according to different needs. After the foaming forming is completed, the mold is demolded, which can be demolded by hand or by clamping equipment.

[0068] As preferred, in step 1, the upper flexible limiting structure is a continuous soft pad 4, and the vertical projections of all magnetic particles in the up-down direction all fall within the area where the continuous soft pad 4 is located. As can be seen, the projection of the magnetic particles in the vertical direction falls within the vertical projection of the continuous soft pad 4, that is, after forming, the continuous soft pad 4 can completely cover and shield all the magnetic particles on the upper side, avoiding the magnetic particles not being covered by the continuous soft pad 4 to cause the aforementioned magnetic displacement and other problems. Moreover, it is better for the integrity of the pillow structure, reducing the instability of the fragmented structure.

[0069] As preferred, the pillow base foaming forming groove m20 is provided with several vertical positioning piles m3 on the groove bottom part, which extend upward and are used for supporting the suspended continuous soft pad piece 4 and positioning the suspended magnetic particles inside the pillow base, the positioning piles m3 are magnetic piles that can be attracted by magnetic objects, the magnetic particles are placed on the positioning piles m3 through the positioning mold m4, the positioning mold m4 is provided with the magnetic positioning holes m40 that are vertically through and are used for placing the magnetic particles from up to down, here, the positioning mold m4 is also mentioned in the foregoing embodiment, which can be used in this process, the magnetic particles are placed on the positioning piles m3 through the positioning mold m4, the positioning mold m4 is movable and is moved by manual or mechanical equipment, the positioning mold m4 is fixedly connected with the handle or support table and other convenient carrying structures on the side, which is used for the circulation of the manual or mechanical equipment, of course, if the magnetic positioning hole m40 is circular and is used for placing the magnetic particles, the magnetic positioning hole m40 is aligned with the top center of the positioning pile m3, each magnetic positioning hole m40 is vertically aligned with the corresponding positioning pile m3, so the layout of the magnetic positioning hole m40 for placing the magnetic particles is consistent with the layout of all the positioning piles m3 for positioning the magnetic particles, to be exact, the number and layout of the hole center are consistent with the top center of the positioning pile m3, in fact, it is the positioning of the two layouts, which can be realized by the existing infrared or laser equipment. It is mentioned above that the size of the positioning mold m4 is smaller and can be placed in the pillow base foaming forming groove m20, but the horizontal size of the positioning mold m4 can be larger than the size of the pillow base foaming forming groove m20, especially the length size of the positioning mold m4 in the left-right direction can be larger than the length size of the pillow base foaming forming groove m20 in the left-right direction, so that the positioning mold m4 can be placed on the lower mold m2 of the mold, but in this structure, the positioning area of the positioning mold m4 is smaller than the horizontal size of the pillow base foaming forming groove m20, so that the lower side of the positioning mold m4 can form the downward protruding extension block m44, the extension block m44 is also provided with holes, which are the extension holes of the magnetic positioning hole m40 downward extending and communicating, the horizontal size of the extension hole is consistent with the horizontal size of the magnetic positioning hole m40 vertically corresponding and communicating.

[0070] As preferred, the continuous soft pad piece 4 is pre-tensioned at the lower surface of the positioning mold m4, after the continuous soft pad piece 4 is placed on the positioning pile m3 with the positioning mold m4, that is, in the embodiment in step 1, the upper flexible limiting structure adopts the continuous soft pad piece 4 and is pressed and adhered on all the positioning piles m3 with the positioning mold m4, then the magnetic particles are placed on the positioning piles m3 from up to down through the magnetic positioning hole m40 on the positioning mold m4, here, the magnetic particles are fixed on each positioning pile m3 through the continuous soft pad piece 4 and magnetic attraction, here, the positioning mold m4 is preferably made of non-ferromagnetic material, for example, non-magnetic steel or aluminum.

[0071] Further, the continuous soft gasket 4 is formed with a plurality of upper and lower through foaming flow shaping holes 40, and the continuous soft gasket 4 is formed with an upper connecting muscle network 41 at the periphery of the foaming flow shaping holes 40. In step S1, one part of the upper connecting muscle network 41 is abutted between the top of the positioning pile m3 and the magnetic particle. In the specific pattern of the continuous soft gasket 4, the magnetic particle is positioned separately from the top of the positioning pile m3, but because of sufficient magnetic attraction, it can still be well attracted and abutted. In this case, if a complete foaming flow shaping hole 40 is clamped between the positioning pile m3 and the magnetic particle, the forming process will affect the foaming material from entering the foaming flow shaping hole 40. In order to reduce this situation, some measures can be taken, for example, the upper part of the positioning pile m3 is a support section m31, and it is best not to abut the complete foaming flow shaping hole 40, but can abut the connecting part of the upper connecting muscle network 41 at the junction of a plurality of foaming flow shaping holes 40, so that each foaming flow shaping hole 40 can have a gap, so that the foaming material can enter the foaming flow shaping hole 40. However, if the size of the top surface of the support section m31 is large, it is inevitable that the entire foaming flow shaping hole 40 will be blocked. At this time, linear grooves can be formed on the front surface of the magnetic particle, so that the upper connecting muscle network 41 where the foaming flow shaping hole 40 clamped by the top surface of the support section m31 and the magnetic particle does not block the inflow and outflow of the foaming material to the foaming flow shaping hole 40. In this way, the foaming flow shaping hole 40 can still be filled with material. Or a groove is formed on the top surface of the support section m31, for example, the top of the support section m31 can form a linear groove or a cross-shaped groove, that is, the positioning groove d, so that there is space for the foaming material to flow into the complete foaming flow shaping hole 40 that is abutted. That is, the upper connecting muscle network 41 where the complete foaming flow shaping hole 40 abutted between the top of the positioning pile m3 and the magnetic particle has a part horizontally and transversely intersected with the positioning groove, and the positioning groove can extend from one complete foaming flow shaping hole 40 to an incomplete foaming flow shaping hole 40. The incomplete foaming flow shaping hole 40 is a foaming flow shaping hole 40 that is not clamped by the top of the positioning pile m3 and the magnetic particle. It is best that the linear groove or the cross-shaped groove is transversely through the top of the support section m31 in the horizontal direction, so that the foaming material can flow in the side surface. Of course, other embodiments can also be used to fill the foaming flow shaping hole 40 with sufficient foaming material.

[0072] As a preferred embodiment, the temperature of the mold is controlled between 25-55 degrees Celsius, and the temperature of the foaming material when injected is controlled between 15-30 degrees Celsius. This can be selected according to the material, and the general recommendation is that the initial injection temperature of the material is lower than the control temperature of the mold, that is, a heating foaming process.

[0073] Further, before step S2, the back of the magnetic particle is pre-connected with a support and anti-inversion pad 5, and after the magnetic particle is placed upside down on the upper side of the continuous soft pad 4 in step S2, the support and anti-inversion pad 5 is on the upper side of the magnetic particle. The pre-connection can be that the back of the magnetic particle is directly bonded to one side surface of the support and anti-inversion pad 5, so that after the magnetic particle is placed upside down, the support and anti-inversion pad 5 is attached. The bonding method can use environmentally friendly glue, or if the support and anti-inversion pad 5 is made of plastic, it can be slightly softened, then the magnetic particle is placed on the support and anti-inversion pad 5, and the upper side of the support and anti-inversion pad 5 is cooled and solidified to connect, of course, a screw or the like can also be used to pass through the support and anti-inversion pad 5 and lock into the back of the magnetic particle, and the back of the magnetic particle is provided with a corresponding hole, of course, other connection methods can also be used.

[0074] Further, in step S2, a plurality of magnetic strips are also arranged in the pillow base foaming forming groove m20 of the mold and are suspended in the pillow base foaming forming groove m20 and are located at the upper side surface of the flexible limiting structure. In step S2, the magnetic strips can be arranged first and then the magnetic particles, or the magnetic particles can be arranged first and then the magnetic strips, or the magnetic particles and the magnetic strips can be arranged simultaneously or staggered. The magnetic strips can also be arranged on the positioning stake m3 through the positioning mold m4. Some of the magnetic body positioning holes m40 opened on the positioning mold m4 are long rectangular, and these holes are used for positioning the magnetic strips from top to bottom. The difference is that the magnetic particles and the positioning stake m3 are one-to-one corresponding, that is, one magnetic particle corresponds to one positioning stake m3, while the magnetic strips correspond to multiple positioning stakes m3, and when arranging, the magnetic strips are also placed upside down on the positioning stake m3, the front edge of the magnetic strip is generally rounded or chamfered, and each magnetic strip is supported and positioned by a row of left and right spaced positioning stakes m3, each row of positioning stakes m3 supports and positions one magnetic strip from below, and there are preferably at least three positioning stakes m3, which are below the left end, right end and middle of one magnetic strip, and the magnetic strip does not need the support and anti-inversion pad 5.

[0075] As a preferred embodiment, in step S3, the foaming material is injected into the base foaming forming groove m20 through a syringe. The syringe can use existing foaming material injection equipment, and the injection of the foaming material can be operated by manual or robotic means.

[0076] Further, in step S3, the foaming material is injected into the base foaming forming groove m20 by a first feeding speed to submerge the upper flexible limiting structure, then the foaming material is injected into the base foaming forming groove m20 by a second feeding speed to submerge the magnetic particles, and then the foaming material is injected into the base foaming forming groove m20 by a third feeding speed until the base foaming forming groove m20 is filled, and the first feeding speed is greater than the second feeding speed. Here, a faster speed is needed for feeding at the beginning of the first stage to make the foaming material flow flat, and the flow flat process is automatically horizontally extended by the meridians of the upper flexible limiting structure to better flow flat, and the aforementioned first, second and third feeding speeds refer to the feeding speed of the overall injector, because the injector here includes multiple injection components, and the injection mode of the injector at each stage needs to be different as much as possible. For example, the injector includes multiple injection guns or nozzles, further, in the first stage, the injector includes multiple injection guns for injecting foaming material at the peripheral positions of the base foaming forming groove m20, and the injection guns are sprayed into the base foaming forming groove m20 at intervals between the periphery of the base foaming forming groove m20 and the periphery of the upper flexible limiting structure, in this stage, the injection speed of all injection guns involved in the injector is generally about 30 cm³ / s, then at least one injection gun is arranged in front, back, left and right until the foaming material submerges the upper flexible limiting structure and the injection gun is removed; in the second stage, the injection gun is moved to the upper side of the magnetic particles to inject the foaming material against the magnetic particles, because the number of magnetic particles is relatively large, the operation of the injection gun is relatively difficult, a vertical nozzle p1 can be used, the nozzle is installed on a pipe rack p2, the number and position of the nozzles p1 installed on the pipe rack p2 correspond one by one with the positioning piles m3, the nozzles p1 spray the foaming material against the central upper surface of the magnetic particles, which needs to maintain the consistency of the injection pressure of each nozzle, this is suitable for the telescopic positioning pile m3, the sensor of the positioning pile m3 detects the pressure on each magnetic particle to maintain consistency as much as possible, so that the magnetic particles can press the foaming material below to a certain extent to achieve the effect of initial foaming and gas exhaust, but the injection pressure should not be too large, otherwise it will cause splashing overflow, if there is a magnetic strip, the injection pressure of the nozzles p1 against the upper surface of the magnetic strip can be kept consistent, it can not be consistent with the injection pressure of the nozzles p1 against the magnetic particles, the process is suitable for relatively regular pillow, if the pillow is not too regular, such as the pillow with large amplitude of arc-shaped concave-convex surface, then the height of the positioning pile m3 and the injection pressure of the nozzle in this stage can be adjusted according to the actual situation, different parameters can be designed according to the position of each magnetic particle, the injection pressure is usually between several hundred and several thousand pascals, and the overall injection speed in this stage is usually about 15 cm³ / s, and the foaming material can be submerged in the magnetic particles.Then it is the third stage, at this time, the injection of foaming material can still be carried out by using the spray pipe p1, but the number of the spray pipe p1 at this time is less than that of the second stage, and the number of the second stage is close to the number of the positioning pile m3, so generally more than 20, and the number of the third stage is generally about 5, and the outlet diameter of the spray pipe p1 of the third stage is larger than that of the second stage, at this time, the injection pressure is not as large as that of the second stage, only the outlet quantity is large, the injection pressure is less than 100 Pa, but the outlet diameter needs to be much larger than the outlet diameter of the spray pipe p1, and the total injection speed is generally about 15-20 cm³ / s, then the several spray pipes p1 at this stage are arranged in the middle of the front and back of the magnetic particle area and are arranged at intervals left and right, so that the several spray pipes p1 can divide the corresponding several radiation areas, at this time, the pressure received by each positioning pile m3 in each area can be detected, and the average pressure of the area can be calculated, if the pressure of a certain area is small, the discharge speed of the spray pipe p1 in the area can be increased, otherwise it can be reduced, so that the pressure of each area is relatively uniform, and the filling material in each area is more uniform, and finally the height position of the positioning pile m3 itself can be adjusted, so that the density and uniformity of the finally formed pillow are more controllable and reasonable. When the foaming material fills the base foaming forming groove m20 in the third stage, the upper mold is closed, the mold temperature is controlled according to the foregoing temperature control, and the molding is completed, generally in 5-10 minutes, then the water temperature of the temperature control mechanism can be cooled, and the cooling time is several minutes, or the water can be drained, and the natural cooling time is about ten minutes, then the demolding is carried out, since the foaming material has good flexibility after foaming, so the foregoing manual lifting or the use of existing equipment for grabbing has little effect on the temporary storage hole structure.

[0077] Through the above production process, the foaming pillow with more stable and reliable structure and comfort can be produced, the process controllability is higher, the details of pillow production are paid more attention to, and one process can be directly completed, without turning and slotting, so that the production efficiency is greatly improved, and the quality is better.

[0078] The above merely illustrates the specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
