Description

Technical Field

[0001] This invention belongs to the field of pillow technology, and more specifically, relates to a gel-cool memory foam pillow. Background Technology

[0002] Sleep pillows are essential home furnishings for ensuring sleep comfort. Memory foam pillows, relying on the viscoelasticity of the material, can conform to the contours of the head and neck and distribute pressure, making them widely used. However, pure memory foam has strong heat insulation properties, and heat is not easily dissipated after the head comes into contact with the pillow surface. Over time, this can lead to a stuffy and hot feeling on the pillow surface, affecting the sleep experience.

[0003] To address the issue of stuffiness in memory foam pillows, existing products typically incorporate a gel sheet on the surface to achieve a cooling effect. However, this large-area gel sheet in contact with the skin also suffers from poor breathability. Since existing memory foam pillows are generally placed directly on the mattress, the airflow space at the bottom is blocked. Under pressure, the ventilation structure also tends to close against the mattress surface, making it difficult to create a continuous heat dissipation pathway throughout the pillow and thus hindering the efficient removal of heat accumulated inside. Summary of the Invention

[0004] By incorporating different layers and elastic mechanisms within the pillow body, the pillow gains a cooling sensation while improving breathability, thus dissipating heat accumulated inside the pillow body and addressing the technical problems existing in the background art.

[0005] This invention is implemented as follows:

[0006] This invention provides a gel-cooling memory foam pillow, comprising a pillow body, within which a gel layer, a cushioning layer, a memory foam layer, and an elastic mechanism are respectively arranged from top to bottom. The gel layer has raised dots and heat dissipation holes. The gel layer and the cushioning layer are fixedly connected, and the cushioning layer and the memory foam layer are also fixedly connected. A groove is formed at the bottom of the memory foam layer, and ribs are provided for the support of adjacent grooves. A first through hole is formed in each groove. A connecting plate is provided between the memory foam layer and the elastic mechanism, and a protrusion is provided on the connecting plate. The protrusion is inserted into the groove, and a distance is provided between the protrusion and the bottom of the groove.

[0007] Based on the above technical solution, the gel cooling memory foam pillow of the present invention can be further improved as follows:

[0008] Furthermore, the elastic mechanism includes a support layer, support bars, and a slider. The support layer is disposed at the lower part of the protrusion, and support bars are respectively disposed on both sides of the lower part of the support layer. A sliding groove is formed on the support bar, and the slider is slidably connected to the support bar.

[0009] Furthermore, the support bar and the slider are arranged in an arc shape.

[0010] Furthermore, a connecting post is provided at the position of the corresponding protrusion at the lower part of the gel layer, and a second through hole is provided on the buffer layer. The connecting post passes through the second through hole and is connected to the buffer layer.

[0011] Furthermore, the cross-section of the connecting column is T-shaped.

[0012] Furthermore, the gel layer is a modified thermoplastic gel; the buffer layer is polyurethane foam; and the memory foam layer is polyurethane slow rebound memory foam.

[0013] Furthermore, the support layer, support strip, and slider are all made of thermoplastic elastomers.

[0014] Furthermore, the heat dissipation holes are disposed between every two of the protrusions.

[0015] Furthermore, the bottom of the heat dissipation hole has no continuous gel base plate, forming a heat dissipation channel that runs through the top and bottom.

[0016] Furthermore, the heat dissipation holes are arranged in a square shape.

[0017] Compared with existing technologies, the beneficial effects of the gel cooling memory foam pillow provided by this invention are:

[0018] It features independent gel bumps with no continuous gel base plate between the bumps. The grooves are directly open and connected to the breathable cushioning layer, allowing heat to be conducted directly downwards, preventing heat buildup on the pillow surface and significantly extending the duration of the cooling sensation. A breathable cushioning layer is placed between the gel layer and the memory foam body. On one hand, it acts as an airflow transfer layer, maintaining airflow even if there is a slight misalignment between the gel grooves and the vertical micropores of the memory foam, preventing the channels from closing under pressure. On the other hand, the cushioning layer can absorb local stress from the gel bumps, weakening the discomfort caused by the hard gel and dispersing the force at the base of the gel bumps.

[0019] The memory foam features vertical through-holes and a ventilated groove on the bottom, allowing hot air to form a continuous airflow channel from top to bottom, improving overall heat dissipation efficiency. Furthermore, the memory foam is placed directly on the rectangular frame of the elastic component, which ensures the bottom of the pillow is stably suspended, providing a stable ventilation space for the ventilation groove on the bottom of the memory foam.

[0035] like Figure 1 , Figure 2 and Figure 5 As shown, the present invention provides a gel cooling memory foam pillow, which includes a pillow body 1, the shape of which includes, but is not limited to, a rectangle;

[0036] Inside the pillow body 1, from top to bottom, there are a gel layer 11, a cushioning layer 12, a memory foam layer 13, and an elastic mechanism. The gel layer 11 has protrusions 111 and heat dissipation holes 112. The gel layer 11 and the cushioning layer 12 are fixedly connected, and the cushioning layer 12 and the memory foam layer 13 are fixedly connected. A groove is formed at the bottom of the memory foam layer, and ribs 131 are provided on the adjacent groove support. A first through hole 132 is formed in each groove. A connecting plate 140 is provided between the memory foam layer 13 and the elastic mechanism. A protrusion 1401 is provided on the connecting plate 140. The protrusion 1401 is inserted into the groove, and a distance is provided between the protrusion 1401 and the bottom of the groove to ensure the breathability of the first through hole 132.

[0037] When the gel comes into contact with the skin, it absorbs heat. If the gel is directly attached to the dense memory foam, the heat will be trapped between the two contact surfaces, causing the interface to heat up rapidly and the cooling sensation to disappear quickly. Therefore, a buffer layer 12 is provided between the gel layer 11 and the memory foam layer 13.

[0038] In some feasible ways, the pillow body 1 is placed in a position including but not limited to a bed, and the user's head contacts the heat dissipation hole 112, bringing a cooling sensation to the user. The heat from the user's head flows into the next layer through the heat dissipation hole 112 on the gel layer 11. The gel layer 11 and the buffer layer 12 are fixedly connected, and the connection position avoids the heat dissipation hole 112, so as not to block the air passage and not to affect the air permeability of the heat dissipation hole 112.

[0039] In some feasible implementations, such as Figure 3 and Figure 4 A connecting post 133 is provided at the bottom of the protrusion 111. The connection method between the connecting post 133 and the gel layer 11 includes, but is not limited to, integral molding. Correspondingly, a second through hole is provided on the buffer layer 12. The connecting post 133 is inserted into the second through hole. Since the cross-section of the connecting post 133 is T-shaped, the connecting post 133 is confined within the second through hole, facilitating the fixation of the gel layer 11 and the buffer layer 12.

[0040] In some feasible implementations, the elastic mechanism includes a support layer 14, a support bar 141, and a slider 142. The support layer 14 is disposed below the protrusion 1401, and support bars 141 are respectively disposed on both sides of the lower part of the support layer 14. A groove is provided on the support bar 141, and the slider 142 is slidably connected to the support bar 141.

[0041] When the user places their head on the pillow body 1, the memory foam layer 13 is compressed due to gravity, and then the support layer 14 presses down. The four symmetrically arranged arc-shaped sliders 142 at the bottom of the support layer 14 slide within the support bar 141 to buffer the stress. The support bar 141 and sliders 142 only undergo slight deformation, and the head pressure is still mainly borne by the memory foam. This retains the original core properties of memory foam, such as slow rebound, pressure distribution, and conforming to the contours of the head and neck. Lateral slippage is prevented through the support bar 141 and sliders 142. No glue is required for bonding, and the normal deformation of the memory foam is not restricted, ensuring the stable and reliable performance of the pillow.

[0042] In some feasible ways, the gel layer 11 is, but is not limited to, modified thermoplastic gel; the buffer layer 12 is, but is not limited to, polyurethane foam, the air pores of the buffer layer 12 reduce the direct large influx of heat into the memory foam, further delaying the heating of the gel, mainly serving as an airflow transfer layer and an interface buffer layer; the memory foam layer 13 is, but is not limited to, polyurethane slow rebound memory foam.

[0043] In some feasible ways, the materials of the support layer 14, support strip 141 and slider 142 include, but are not limited to, thermoplastic elastomers.

[0044] In some feasible methods, heat dissipation holes 112 are provided between every two protrusions 111. Multiple independent protrusions 111 are provided on the gel layer 11, and heat dissipation holes 112 are provided between every two protrusions 111. The bottom of the heat dissipation holes 112 has no continuous gel base plate, forming a heat dissipation channel that runs through the top and bottom, which facilitates heat dissipation for the user's head.

[0045] In some feasible ways, the heat dissipation holes 112 are arranged in a square shape, including but not limited to square shapes.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
