Description
Technical Field
[0001] The utility model relates to the application field of EVA material floor mats, in particular to a breathable EVA sheet material. Background Art
[0002] EVA is a copolymer of ethylene and vinyl acetate. The application field of EVA is quite wide. The annual market consumption in my country is constantly increasing, especially in the shoemaking industry. It is used in the soles and interior materials of mid-to-high-end tourist shoes, hiking shoes, slippers, and sandals. It is also widely used in the new energy field, such as photovoltaic materials, solar cell adhesives, etc.
[0003] According to the processing, EVA can be divided into sheets, coils, glue coating, adhesive backing, molding, and embossing. EVA sheets can be used to make floor mats. The hardness of high-foamed EVA materials is 5% to 40%. This material has good softness and elasticity and is often used to make packaging materials, shoes, toys, etc. The secondary foaming hardness of EVA materials is 40% to 55%. This material has a higher hardness and good elasticity. It is often used to make sports equipment, auto parts, etc. The single-foamed EVA material has a foaming hardness between 55% and 75%, which is relatively high and is mainly used to make harder products.
[0004] EVA can be used to make floor mats in our lives, such as floor mats inside cars, floor mats in the bathroom at home including the door, and EVA splicing crawling mats for children. The existing crawling mats have poor air permeability. When it rains, the crawling mats are not easy to dry after getting damp. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a breathable EVA sheet to solve the technical problems mentioned in the above background.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a breathable EVA sheet, comprising an upper floor mat, wherein a plurality of groups of longitudinal exhaust holes are opened inside the upper floor mat, and a plurality of groups of transverse exhaust holes are opened inside the upper floor mat, and an anti-slip protrusion is arranged on the top of the upper floor mat, a lower floor mat is arranged at the bottom of the upper floor mat, and vertical exhaust holes are opened inside the lower floor mat, and the lower floor mat and the upper floor mat are bonded as a whole.
[0007] By adopting the above technical solution, by arranging multiple groups of anti-skid protrusions on the top of the upper floor mat, the friction of the floor mat can be increased, making it difficult for users to slip, and the anti-skid protrusions and the upper floor mat are made of soft EVA material with a soft texture, which can improve the user's feeling of use. The upper floor mat is distributed with longitudinal exhaust holes and transverse exhaust holes, and the intersection nodes of the longitudinal exhaust holes and the transverse exhaust holes are located in the same vertical direction as the anti-skid protrusions. Therefore, when the user steps on it, the upper floor mat mainly acts on the anti-skid protrusions, so that when the floor mat sinks, the height of the anti-skid protrusions can make up for the height of the exhaust hole being pressed down, and the anti-skid protrusions are pressed, which is conducive to the discharge of water vapor inside the longitudinal exhaust holes and the transverse exhaust holes.
[0008] The utility model is further configured such that a node where the longitudinal exhaust hole and the transverse exhaust hole intersect is located in a vertical direction and coincides with the anti-slip protrusion.
[0009] By adopting the above technical solution, by setting the intersection nodes of the longitudinal exhaust holes and the transverse exhaust holes to overlap with the anti-slip protrusions in the vertical direction, when the anti-slip protrusions are pressed and sink, not only the longitudinal exhaust holes and the transverse exhaust holes can be squeezed, but the sinking height of the anti-slip protrusions can also compensate for the sinking height of the longitudinal exhaust holes and the transverse exhaust holes, so that the user will not sink excessively when stepping on the upper floor mat.
[0010] The utility model is further configured that the upper floor mat is made of high-foamed soft EVA material.
[0011] By adopting the above technical solution and using high-foaming soft EVA material to make the upper floor mat, the user's stepping experience is better.
[0012] The utility model is further configured that a plurality of groups of glass fiber reinforcement layers are installed on the top of the lower floor mat, and the glass fiber reinforcement layers are high-strength materials.
[0013] By adopting the above technical solution, multiple groups of glass fiber reinforcement layers are installed on the top of the lower floor mat. Glass fiber is a high-strength material that can improve the strength and toughness of the lower floor mat, thereby increasing the service life of the floor mat.
[0014] The utility model is further configured that the lower floor mat is made of secondary foamed semi-rigid EVA material.
[0015] By adopting the above technical solution, by setting the lower floor mat as a secondary foamed semi-rigid EVA material, the lower floor mat has a certain toughness and hardness, which can support the upper floor mat.
[0016] The utility model is further configured that the anti-skid protrusions are provided in multiple groups, and the multiple groups of anti-skid protrusions are made of the same material as the upper floor mat.
[0017] By adopting the above technical solution and providing multiple groups of anti-slip protrusions, the friction of the upper floor mat can be increased to prevent users from falling.
[0018] The utility model is further configured that the vertical exhaust holes are provided with a plurality of groups, and the plurality of groups of vertical exhaust holes are distributed between two adjacent groups of glass fiber reinforced layers.
[0019] By adopting the above technical solution and providing a plurality of groups of vertically distributed vertical exhaust holes, part of the water vapor of the upper floor mat can be discharged from the vertical exhaust holes.
[0020] The utility model is further configured that a grid-shaped base is provided at the bottom of the lower floor mat, and the grid-shaped base is provided with a plurality of groups of air-permeable grooves.
[0021] By adopting the above technical solution, the grid-shaped base can support the lower floor mat and facilitate the discharge of water vapor from the lower floor mat.
[0022] The utility model is further configured such that a plurality of groups of vertical exhaust holes are evenly distributed inside the grid-shaped base.
[0023] By adopting the above technical solution, multiple groups of vertical exhaust holes are evenly distributed inside the grid-shaped base, so that water vapor from the lower floor mat enters the grid-shaped base through the vertical exhaust holes and is then discharged to the outside.
[0024] The utility model is further configured that the grid-shaped base is a one-time foamed hard EVA material.
[0025] By adopting the above technical solution, by setting the grid-shaped base to be a hard EVA material, since the grid-shaped base is in contact with the ground, the grid-shaped base has high hardness, is wear-resistant, and has a long service life.
[0026] In summary, the utility model mainly has the following beneficial effects:
[0027] 1. The utility model can increase the friction of the floor mat by arranging multiple groups of anti-skid protrusions on the top of the upper floor mat, so that the user is not easy to slip, and the anti-skid protrusions and the upper floor mat are made of soft EVA material with soft texture, which can improve the user's feeling of use. The upper floor mat is distributed with longitudinal exhaust holes and transverse exhaust holes, and the intersection nodes of the longitudinal exhaust holes and the transverse exhaust holes are located in the same vertical direction as the anti-skid protrusions. Therefore, when the user steps on the upper floor mat, the anti-skid protrusions mainly act on the anti-skid protrusions, so that when the floor mat sinks, the height of the anti-skid protrusions can make up for the height of the exhaust holes under pressure, and the anti-skid protrusions are under pressure, which is conducive to the discharge of water vapor inside the longitudinal exhaust holes and the transverse exhaust holes.
[0028] 2. The utility model provides a lower floor mat, which is made of semi-rigid EVA material and has a certain hardness. It is bonded with the upper floor mat to improve the overall firmness of the floor mat. Multiple groups of glass fiber reinforcement layers are installed in the lower floor mat to further improve the strength of the floor mat. The lower floor mat is provided with vertical exhaust holes, which is conducive to the downward penetration of water vapor in the upper floor mat.
[0029] 3. The utility model arranges a grid-shaped base at the bottom of the lower floor mat. The grid-shaped base is made of hard EVA material, which has a relatively high hardness and can effectively support the floor mat. The grid-shaped base has multiple sets of air permeable grooves, which are conducive to the discharge of humid air. At the same time, the floor mat can be rolled up as a whole along the axial direction of the air permeable grooves, so that the user can reduce the occupied space when rolling up the floor mat.

[0039] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1
[0040] A breathable EVA sheet, such as Figure 1-7 As shown, it includes an upper floor mat 1, a plurality of groups of longitudinal exhaust holes 3 are opened inside the upper floor mat 1, and a plurality of groups of transverse exhaust holes 4 are opened inside the upper floor mat 1, the longitudinal exhaust holes 3 and the transverse exhaust holes 4 can help the upper floor mat 1 to discharge water vapor, and the top of the upper floor mat 1 is provided with an anti-skid protrusion 2, the anti-skid protrusion 2 can increase the friction of the upper floor mat 1, thereby preventing the user from falling, a lower floor mat 5 is provided at the bottom of the upper floor mat 1, and vertical exhaust holes 9 are opened inside the lower floor mat 5, and the lower floor mat 5 and the upper floor mat 1 are bonded as a whole, and the vertical exhaust holes 9 can help the upper floor mat 1 and the lower floor mat 5 to discharge water vapor.
[0041] See also Figure 3 The node where the longitudinal exhaust holes 3 and the transverse exhaust holes 4 intersect is located in the vertical direction and coincides with the anti-slip protrusion 2. By setting the intersection node of the longitudinal exhaust holes 3 and the transverse exhaust holes 4 to coincide with the anti-slip protrusion 2 in the vertical direction, when the anti-slip protrusion 2 is pressed and sunken, not only the longitudinal exhaust holes 3 and the transverse exhaust holes 4 can be squeezed, but also the sunken height of the anti-slip protrusion 2 can make up for the sunken height of the longitudinal exhaust holes 3 and the transverse exhaust holes 4, so that the user will not sink excessively when stepping on the upper floor mat 1.
[0042] See also Figure 3 The upper floor mat 1 is made of high-foamed soft EVA material. By using high-foamed soft EVA material to make the upper floor mat 1, the user's stepping experience is better.
[0043] See also Figure 4 A plurality of glass fiber reinforced layers 6 are installed on the top of the lower floor mat 5. The glass fiber reinforced layers 6 are high-strength materials. By installing a plurality of glass fiber reinforced layers 6 on the top of the lower floor mat 5, glass fiber is a high-strength material, which can improve the strength and toughness of the lower floor mat 5, thereby improving the service life of the floor mat.
[0044] See also Figure 5 The lower floor mat 5 is a secondary foamed semi-rigid EVA material. By setting the lower floor mat 5 to be a secondary foamed semi-rigid EVA material, the lower floor mat 5 has a certain toughness and hardness, which can support the upper floor mat 1.
[0045] See also Figure 2 There are multiple groups of anti-skid protrusions 2, and the multiple groups of anti-skid protrusions 2 are made of the same material as the upper floor mat 1. By setting multiple groups of anti-skid protrusions 2, the friction of the upper floor mat 1 can be increased to prevent users from falling.
[0046] See also Figure 5 There are multiple groups of vertical exhaust holes 9, and the multiple groups of vertical exhaust holes 9 are distributed between two adjacent groups of glass fiber reinforced layers 6. By setting multiple groups of vertically distributed vertical exhaust holes 9, part of the water vapor of the upper floor mat 1 can be discharged from the vertical exhaust holes 9. Embodiment 2
[0047] A breathable EVA sheet, such as Figure 6-7 As shown, a grid base 7 is provided at the bottom of the lower floor mat 5, and the grid base 7 is provided with multiple groups of breathable grooves 8. The grid base 7 can support the lower floor mat 5 and facilitate the discharge of water vapor from the lower floor mat 5.

By evenly distributing the plurality of vertical exhaust holes 9 inside the grid-like base 7, the water vapor of the lower floor mat 5 enters the grid-like base 7 through the vertical exhaust holes 9 and is then discharged to the outside.
[0049] See also Figure 7 The grid-shaped base 7 is a one-time foamed hard EVA material. By setting the grid-shaped base 7 to be a hard EVA material, since the grid-shaped base 7 is in contact with the ground, the grid-shaped base 7 has high hardness, is wear-resistant, and has a long service life.
[0050] The working principle of the utility model is as follows: when the floor mat is damp and there is a lot of humid air inside, the user steps on the anti-skid protrusion 2, causing the anti-skid protrusion 2 to sink, thereby squeezing the longitudinal exhaust holes 3 and the transverse exhaust holes 4, so that part of the water vapor inside the upper floor mat 1 is discharged through the longitudinal exhaust holes 3 and the transverse exhaust holes 4, and part of it flows to the vertical exhaust holes 9 of the lower floor mat 5, and then the water vapor is discharged to the ground, and the water vapor can also be discharged from the ventilation groove 8.
[0051] When the user needs to roll up the floor mat, the user can simply roll up the floor mat with the multiple air permeable grooves 8 as the axis. Since the upper floor mat 1 is made of soft EVA and the lower floor mat 5 is made of semi-hard EVA, there will be no obstruction to rolling up, and the grid-like base 7 is separated by multiple groups of air permeable grooves 8, which will not affect the rolling up.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
