Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of pillows, and particularly relates to a processing method of a pillow with a deformable neck support body, the pillow and a mold. BACKGROUND

[0002] In order to provide good support for the neck, the existing pillow generally sets a material with higher hardness at the neck position than other positions of the pillow. However, in order to obtain the hard support, the structure is generally in the form of a block or other shapes, and the degree of deformation is limited, which is difficult to adapt to various pillow pressure values. More specifically, in the prior art, there is a type of pillow which is provided with a cylindrical support on one side in the length direction of the pillow, and the pillow core has a corresponding through cylindrical cavity at the position on one side. In order to facilitate the placement of the cylindrical support into the cylindrical cavity, an installation port is also cut along the edge of the wall surface of the cylindrical cavity, and the production steps are more, and the material of the cylindrical support is compressed to provide support when the human body is in a pillow position, and the fitting effect and support effect on the physiological curve of the human neck are limited.

[0003] Therefore, the applicant designs a pillow with a deformable neck support body, which includes a pillow core and a deformable neck support body in the pillow core. The pillow core forms a cavity for accommodating the neck support body. The neck support body includes an upper portion, a connecting portion, and a lower portion connected in sequence (the cavity between the upper portion and the lower portion of the neck support body forms a ventilation passage). When the two parts of the pillow core are produced independently and then spliced, glue is usually used. In order to avoid or reduce the use of glue, an integrated foaming method can be used, that is, the already produced neck support body is placed in the mold when foaming the pillow core.

[0004] However, when the conventional foaming method is generated, the foaming material of the pillow core will fill the deformation space, so that the neck support body cannot be normally deformed to match the physiological curve of the human cervical spine. The technical personnel in the field need to solve the technical problem of reserving the deformation space of the neck support body when the pillow core is foamed. SUMMARY

[0005] In view of the deficiencies in the prior art that there is no pillow with a deformable neck support body and no method for assembling the pillow core and the neck support body, the present application provides a processing method of a pillow with a deformable neck support body. The present application also discloses a pillow obtained by using the processing method and a mold for processing the pillow.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: the processing method of the pillow with the deformable neck support body comprises:

[0007] Step S1, a neck support body is processed, the neck support body includes an upper portion, a lower portion, and a connecting portion connecting the two, and a deformation space is formed between the upper portion and the lower portion of the neck support body;

[0008] Step S2: Fix the airbag and neck support in the mold that forms the pillow core, and inflate the airbag so that the airbag occupies the deformation space.

[0009] Step S3: Inject raw materials into the mold for forming the pillow core to obtain the pillow core;

[0010] Step S4: Deflate the airbag to separate it from the pillow core.

[0011] As an improvement, in step S2, a hollow support column is set on the mold for forming the pillow core, and an air bladder is connected to the end of the hollow support column. The neck support body is fixed on the hollow support column.

[0012] In step S4, the airbag, hollow support, and pillow core are separated.

[0013] As an improvement, in step S2, after the airbag is inflated, a release agent is applied to the surface of the airbag.

[0014] As an improvement, check the airbag for leaks before applying the release agent.

[0015] As an improvement, in step S4, the airbag retracts into the hollow support after deflation.

[0016] As an improvement, the airbag pressure is checked after inflation to see if it is within the preset range.

[0017] As an improvement, the air pressure of the airbag is monitored during the pillow core forming process to ensure it is within the preset range.

[0018] As an improvement, there are multiple airbags; the two end faces of the airbag group formed after the multiple airbags are inflated are flush with the neck brace.

[0019] As an improvement, the manufacturing method for a pillow with a deformable neck support also includes:

[0020] Step S5: Process a breathable channel on the side of the pillow core that connects with the deformation space.

[0021] A pillow with a deformable neck support is obtained by the aforementioned processing method. The pillow includes a pillow core and a neck support. The pillow core has a cavity, and the neck support is located in the cavity. The neck support includes an upper part, a lower part, and a connecting part connecting the two. The area between the upper part and the lower part of the neck support forms a deformation space. The pillow core and / or the neck support have process release holes.

[0022] As an improvement, the length of the neck support is slightly less than the length of the pillow; and / or,

[0023] The neck brace is C-shaped or U-shaped; and / or,

[0024] The pillow core completely encloses the neck support.

[0025] A mold for processing a pillow with a deformable neck support, the mold comprising:

[0026] upper mold;

[0027] Lower mold;

[0028] Hollow support column with inflation / deflation channels;

[0029] An airbag is installed at the end of a hollow support column and has an inflation / deflation channel connected to the hollow support column.

[0030] The air pump assembly inflates the airbag;

[0031] The mold cavity formed by the upper and lower molds is adapted to the shape of the pillow core, and the end of the hollow support column is located in or connected to the mold cavity.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The processing method of the pillow with a deformable neck support of the present invention involves filling the area between the upper and lower parts of the neck support by inflating the air bladder, and deflating and removing the air bladder after the pillow core is formed. This ensures that the area between the upper and lower parts of the pillow core is not filled or occupied by the expansion of the foam material after the pillow core is formed, and the neck support still has deformation space. The neck support with deformation space can provide support for the physiological curve of the neck through its own bending deformation rather than compression deformation. It also allows the neck support to tightly wrap the air bladder after the air bladder expands, thereby limiting the neck support itself. There is no need to set up additional structures for the position constraint of the neck support. The neck support is built in during the foaming of the pillow core, and the interface between the pillow core and the neck support is more firmly bonded during the foaming process. There is no need to open an installation port or installation space on the pillow core by cutting or other means. There is no need to use adhesives or other adhesive media, and there is no need to worry about displacement caused by the neck support not being firmly fixed.

[0034] 2. The pillow of the present invention has a deformable neck support body. The pillow core has a cavity, and the neck support body is located in the cavity. The neck support body includes an upper part, a lower part, and a connecting part connecting the two. The area between the upper part and the lower part of the cavity forms a deformation space. The pillow core wraps the neck support body by setting the cavity. Depending on the fixed position of the neck support body, there are process release holes on the pillow core or the neck support body to facilitate the pillow core to complete foaming and be bonded and fixed to the neck support body and then detach from the deflated air bladder.

[0035] 3. The mold for processing a pillow with a deformable neck support of the present invention provides a hollow support extending from the mold wall to the middle position of the mold cavity, and provides an air bladder at the end of the hollow support. This prevents the middle position of the mold cavity from being occupied by the expansion of the foam material. Furthermore, the expansion of the air bladder supports the deformation space of the neck support, thereby effectively constraining the position of the neck support. Attached Figure Description

[0057] The technical solutions of the embodiments of the present invention will be explained and described below. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0058] See Figures 1 to 14 The present invention discloses a method for processing a pillow with a deformable neck support. The pillow includes a pillow core and a neck support. The pillow core has a cavity, and the neck support is located in the cavity. The neck support includes an upper part, a lower part, and a connecting part connecting the two. The area between the upper part and the lower part of the cavity forms a deformation space.

[0059] The manufacturing methods for pillows with deformable neck supports include:

[0060] Step S1: Process to obtain a neck support body. The neck support body includes an upper part, a lower part, and a connecting part connecting the two. The area between the upper part and the lower part of the neck support body forms a deformation space.

[0061] Step S2: Fix the airbag and neck support in the mold that forms the pillow core, and inflate the airbag so that the airbag occupies the deformation space.

[0062] Step S3: Inject raw materials into the mold for forming the pillow core to obtain the pillow core;

[0063] Step S4: Deflate the airbag to separate it from the pillow core.

[0064] The present invention discloses a method for processing a pillow with a deformable neck support. The pillow's structure differs from existing methods, allowing the neck support to deform over a wider range and thus have broader applicability. In this method, an air bladder is inflated to fill the area between the upper and lower portions of the neck support. After the pillow core is formed, the air bladder is deflated and removed, creating a deformation space for the neck support in the area between the upper and lower portions. By inflating the air bladder to fill this area and then deflating it after the pillow core is formed, the area between the upper and lower portions is not occupied by the foamed material, ensuring the neck support still has deformation space. The air bladder's shape matches the inner wall of the neck support, i.e., the deformation space. The air bladder, through inflation, restrains the neck support in a specific position, eliminating the need for additional fixing structures in the pillow core foam mold.

[0065] Example 1

[0066] See Figure 1 and Figure 2 The processing method of the pillow 01 with a deformable neck support according to Embodiment 1 of the present invention includes:

[0067] Step S1: Process to obtain a neck support body. The neck support body includes an upper part 21, a lower part 22 and a connecting part 23 connecting the two. The area between the upper part 21 and the lower part 22 of the neck support body forms a deformation space.

[0068] Step S2: A hollow support column 5 is set on the mold 02 that forms the pillow core 1. The end of the hollow support column 5 is connected to the air bladder 6. The neck support is fixed on the hollow support column 5. The air bladder 6 is inflated so that the air bladder 6 completely occupies the deformation space. Check whether the air bladder 6 leaks air and check whether the air pressure of the air bladder 6 is within the preset range. When the air pressure of the air bladder 6 meets the requirements, a release agent is applied to the surface of the air bladder 6. Before the neck support is fixed on the hollow support column 5, the release agent is applied to the surface of the air bladder. By inflating the air bladder 6, applying the release agent, deflating the air bladder 6, fixing the neck support on the hollow support column 5, and inflating the air bladder 6 again, the release agent covers a larger surface of the air bladder 6. This avoids the situation where the release agent cannot completely cover the part of the air bladder surface that is in contact with the inner wall of the cavity 11 due to the obstruction of the neck support, which would cause the air bladder to stick to the foam material.

[0069] Step S3: Inject raw materials into the mold 02 that forms the pillow core 1 to obtain the pillow core 1. During the molding process of the pillow core 1, monitor whether the air pressure of the airbag 6 is within the preset range. The molding process of the pillow core 1 is a foaming process, which is a chemical reaction. At this time, the internal temperature of the pillow core 1 is relatively high, and the air expands due to heat, causing the air pressure value of the airbag 6 to increase to a certain extent. By monitoring whether the air pressure of the airbag 6 is within the preset range during the molding process of the pillow core 1, on the one hand, as the foaming process continues, the air pressure value is monitored to gradually increase, and a certain amount of air is released from the airbag to avoid the airbag rupture due to excessive air pressure. On the other hand, if the air pressure value decreases and becomes equal to atmospheric pressure, it can be identified that the airbag wall has been ruptured and damaged due to high temperature.

[0070] In this embodiment, the neck support is made of polyurethane foam material, and the raw material injected into the mold 02 is a foam mixture or a latex foam mixture.

[0071] Step S4: Deflat the airbag 6 to separate the airbag 6, hollow support column 5, and pillow core 1;

[0072] Step S5: Process a breathable channel 12 on the side of the pillow core 1 that is connected to the deformation space.

[0073] In this embodiment, there are multiple airbags 6; the two end faces of the airbag group 6 formed after the multiple airbags 6 are inflated are flush with the neck support body. By having multiple airbags 6, the volume of a single airbag 6 is reduced, avoiding the situation where the airbag 6 is too large to easily separate from the pillow 01 after deflating.

[0074] In other embodiments, after deflating, air is continuously pumped out of the airbag 6, causing it to retract into the hollow support column 5. This avoids or reduces friction between the airbag 6 and the pillow 01 during removal. By housing the airbag within the hollow support column 5, friction between the airbag 6 and the pillow core 1 or neck support is reduced when the hollow support column 5 separates from the foamed pillow core 1, thereby improving product quality by reducing friction.

[0075] See Figures 3 to 5 The pillow 01 with a deformable neck support 2 includes:

[0076] Pillow core 1;

[0077] Neck brace 2;

[0078] The pillow core 1 has a cavity 11, and the neck support 2 is located in the cavity 11. The neck support 2 is located at the edge of the pillow core 1 in the width direction. The neck support 2 includes an upper part 21, a lower part 22, and a connecting part 23 connecting the two. The area of ​​the cavity 11 between the upper part 21 and the lower part 22 of the neck support 2 forms a deformation space 111. When the upper part 21 and the lower part 22 are pressed close to each other and squeeze the deformation space 111, the connecting part 23 deforms. When the user lies on pillow 01, the upper part 21 and the lower part 22 are pressed close to each other, forming an opening where the connecting part 23 is not located. This opening provides space for deformation under pressure, improving the sensitivity of the deformation. This allows the upper part 21 to move away from the connecting part 23 while being pressed down. The upper part 21 can match the height of the user's neck through pressure displacement, and its convex curved support surface always conforms to and supports the curve of the user's neck. Furthermore, by bending the connecting part, it accumulates rebound force, which causes the upper part 21 to return to its unpressurized position, providing elastic support. When the opening faces the center of the pillow core 1, the upper part 21 can extend to support the back of the head. When the opening is located at the edge of the pillow core 1, the upper part 21 can extend to support the neck and shoulder transition area, and also facilitates the horizontal placement of the hollow support 5 (e.g., Figure 7 As shown, the airbag 6 enters the deformation space 111 through the opening and inflates to support the neck support 2, eliminating the need for a release hole on the neck support 2 and improving processing efficiency.

[0079] In this embodiment, the connecting portion 23 is located on the same side as the upper portion 21 and the lower portion 22, while the other side of the upper portion 21 and the lower portion 22 is an opening. The neck support 2 is approximately C-shaped. The approximately C-shaped neck support 2 also allows for a smooth connection and transition between the curved upper portion 21 and the curved connecting portion 23, reducing the possibility of the user experiencing a foreign body sensation. In addition, the small opening and large cavity of the neck support 2 facilitates the wrapping and clamping of the inflated airbag 6. The neck support 2 not only clamps the airbag 6 but is also constrained and limited by the airbag 6 itself.

[0080] In this embodiment, reference Figure 5 The cavity 11 has an egg-shaped cross-section. The volume of the cavity 11 is slightly larger than that of the neck support 2 and the deformation space 111, leaving room for the upper part 21 to move under pressure.

[0081] In other embodiments, the neck support 2 may also be U-shaped (with two bends).

[0082] In this embodiment, the pillow core 1 is integrally formed. See also... Figure 6 The process release hole only appears on the neck support body 2. At this time, the neck support body 2 is supported by the mold 02. The processing hole 221 is opened on the neck support body 2, so that the process hole 13 does not need to appear on the pillow core 1.

[0083] In other embodiments, see Figure 7The process-specific release hole can appear only on the pillow core 1. At this time, the position of the hollow support 5 corresponds to the opening of the neck support 2, and the neck support 2 is supported by the airbag 6 (in order to reduce the suspended length of the hollow support 5, the opening of the neck support 2 can be oriented towards the same side edge).

[0084] In this embodiment, the pillow core 1 has a ventilation channel 12, which includes multiple ventilation holes located on the two end face sidewalls along the length of the cavity 11. The ventilation holes can be obtained directly during the molding of the pillow core 1, or they can be obtained separately after the pillow core 1 is molded.

[0085] In this embodiment, the neck support 2 has a higher hardness than the pillow core 1. The pillow core 1 uses ordinary sponge, while the neck support 2 uses high-hardness sponge or high-resilience sponge. The pillow core 1 has a lower hardness, providing a soft support feel, while the neck support 2 has a higher hardness, providing support force. Furthermore, the upper part 21 can always maintain an upward-curving support shape, ensuring a good fit to the neck curve. The connecting part 23 can accumulate rebound force after being bent under pressure, thus providing more elastic support. Alternatively, the neck support 2 and the pillow core 1 can be made of different types of materials with different hardnesses. For example, the pillow core 1 can be made of latex, and the neck support 2 can be made of polyurethane sponge. Latex provides a softer and more breathable surface support, while polyurethane sponge provides rebound support generated by compression deformation.

[0086] Example 2

[0087] See Figures 8 to 14 The only difference between Example 2 and Example 1 is the shape of the pillow core and the neck support.

[0088] In this embodiment, the pillow core adopts an ergonomic design with a sunken fossa area and a forward-extending neck support.

[0089] See Figure 8 In this embodiment, the pillow core 1 adopts an ergonomic design with a sunken fossa area and a forward-extending neck support.

[0090] See Figure 9 In this embodiment, the upper part 21 of the neck support 2 is lower in the middle and higher at both ends along its length. The curvature of the upper part 21 of the neck support 2 presents a structure with higher sides and a lower middle, providing stable support while also providing a wrap-around neck support effect. The sunken fossa area of ​​the pillow core 1 corresponds to the middle of the neck support 2.

[0091] See Figures 10 to 14 In this embodiment, mold 02 includes:

[0092] Upper mold 3;

[0093] Lower mold 4;

[0094] Hollow support column 5 has an inflation / deflation channel;

[0095] Airbag 6 is installed at the end of hollow support column 5 and connected to the inflation / deflation channel of hollow support column 5;

[0096] The air pump assembly inflates the airbag 6;

[0097] Solenoid valve;

[0098] Air pressure detection component, which detects the air pressure in airbag 6;

[0099] Controller, which controls the solenoid valve and air pump assembly.

[0100] In this embodiment, the air pressure detection component is integrated into the controller, and each airbag 6 is connected to the air pressure detection component through multiple independent air pressure detection pipelines.

[0101] In this embodiment, the hollow support column 5 is disposed on the lower mold 4, and the hollow support column 5 and the lower mold 4 are an integral structure. The lower mold 4 has a corresponding opening. The hollow support column 5 is tubular, with one end located in the mold cavity, and the other end of the tubular shape integrally connected to the cavity wall of the lower mold 4. The lower mold 4 is provided with a corresponding opening that communicates with the inflation / deflation channel of the hollow support column 5, so that the air pump assembly can be connected to the airbag 6 through the opening and the inflation / deflation channel, or the air pump assembly can be connected to the airbag 6 through an air pipe located within the opening and the inflation / deflation channel.

[0102] In other embodiments, the hollow support column 5 and the lower mold 4 are independent and separable structures. The lower mold 4 has mounting holes for the hollow support column 5 to pass through. The hollow support column 5 passes through the mounting holes from bottom to top, so that the end of the hollow support column 5 is located in the mold cavity. By further configuring the hollow support column 5 as a detachable and assembleable structure, the hollow support column 5 can be replaced as a whole, facilitating the processing of different models of pillows 01. It also facilitates the easy removal of the pillow 01 after first separating the hollow support column 5 and its end airbag 6 from the mold 02 from top to bottom.

[0103] In this embodiment, the hollow support column 5 has threads at its end, and the air inlet of the airbag 6 is fitted onto a ring nut (not shown in the figure). By rotating and tightening the ring nut onto the threads, the airbag 6 can be fixed to the end of the hollow support column 5. The detachable structure for fixing the airbag 6 to the hollow support column 5 also facilitates replacement of the airbag 6 if it is damaged.

[0104] In this embodiment, the air pump assembly is connected to the airbag 6 via a solenoid valve, and air is also released via the solenoid valve. The solenoid valve is connected to the controller via an independent circuit, allowing the controller to adjust the energization / de-energization state of the solenoid valve based on data from the air pressure detection assembly. A two-position three-way solenoid valve is selected.

[0105] In this embodiment, the shapes of the mold cavities of the upper mold 3 and the lower mold 4 are adapted to the shape of the pillow core 1. Other specific structures of the upper mold 3 and the lower mold 4 can be found in the accompanying drawings and prior art.

[0106] In this embodiment, the hollow support column 5 is stepped, and its support for the neck support body 2 is achieved by... Figure 5 The pillow core 1 and the neck support 2 have different shapes.

[0107] In this embodiment, in order to separate the hollow support column 5 and the airbag 6 from the pillow 01, the mold 02 also includes a lifting mechanism for driving the hollow support column 5 to rise and fall.

[0108] In other embodiments, to avoid or reduce friction between the airbag 6 and the pillow 01, an air pump is provided to extract air from the airbag 6, causing the airbag 6 to retract into the hollow support column 5.

[0109] In this embodiment, the dimensions of the neck support 2 and the pillow core 1 are for illustrative purposes only and do not necessarily correspond to the actual dimensions.

[0110] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes, but is not limited to, the content described in the above specific embodiments. Any modifications that do not depart from the functional and structural principles of the present invention will be included within the scope of the claims.
