Description

Self-inflating silicone airbag cushion

[Technical Field]

The present invention relates to an air cushion, and more particularly to a self-inflating silicone airbag cushion.

【Background technique】

At present, the air-cushion products of the airbag structure have been recognized by many consumers because of their light weight and good comfort. The airbag-type air cushion products currently marketed and recognized by consumers are basically equipped with an inflator, and the airbag is leaked due to long-term use. After gas and internal helium, it is restored by the inflator, but such a product has a complicated structure, high production cost, and is easily damaged.

Airbag-type air cushion products that are currently sold on the market are basically made of rubber or other materials with good air tightness, so as to minimize the leakage of gas in the airbag and prolong the service life of the product. However, even if the airtightness of the material is good, with the extension of time, the heavy pressure during use will cause the airbag to slowly leak. After the product leaks, the airbag can not rebound and the product loses its proper value. Functional function, so the existence of defects, resulting in such a non-inflatable structure of the product has a short service life, and the quality of the use process continues to decline and other reasons are not recognized by consumers.

Therefore, the present invention has emerged.

The self-inflating silicone airbag air cushion as described above is characterized in that the substrate is provided with a through hole between each of the upper silicone airbags.

The self-inflating silicone airbag air cushion as described above is characterized in that the other side of the substrate is provided with a plurality of lower-layer silicone airbags which are independent of each other and are convex and communicate with the upper silicone airbag, and an upper airflow passage is formed between each upper silicone airbag. A lower airflow passage is formed between each of the lower silicone airbags and communicates with the upper airflow passage through the through hole. The lower silicone airbag has a wall thickness of 0.3 mm to 2 mm, a height of 3 mm to 50 mm, and a volume of 100 cubic millimeters to 300,000 cubic meters. Millimeter.

The self-inflating silicone airbag air cushion as described above, characterized in that the underlying silicone airbag has a wall thickness of 0.4 Mm~1.5mm, height 5mm~30mm, volume 200mmmm to 100000m3.

The self-inflating silicone airbag air cushion as described above is characterized in that the underlying silicone airbag has a wall thickness of 0.6 Mm~1.2mm, height 8mm~20mm, volume 400cm to 20,000mm.

The self-inflating silicone airbag air cushion as described above is characterized in that the substrate is provided with a suction cup for adsorbing the self-inflating silicone airbag air cushion to the support surface.

The self-inflating silicone airbag air cushion as described above is characterized in that the upper silicone airbag and the lower silicone airbag are provided with electronic components that are triggered to emit light or occur when the air cushion is pressed.

Compared with the prior art, the invention has the following advantages: the invention has the advantages of simple structure, no need to inflate, the airbag can adjust the air pressure by itself, and the air pressure in the airbag is always kept constant, so it can be used for a long time.

The invention adopts a silica gel material to manufacture an airbag air cushion. The molecular main chain of the silica gel material is an SI-O structure, which is completely different from the main chain CC structure of the existing rubber, elastomer and the like, and is a new material between organic and inorganic materials. . Therefore, many properties and uses of silica gel are completely different from those of commonly used rubbers and elastomers.

Silica gel has very good gas permeability (poor air tightness) and is far superior to other rubber materials. Under the same conditions, the permeability of silica gel is better than 10 times that of ordinary rubber and elastomer. The rebound elasticity of silica gel is very good. It is widely used in computer keyboards, telephone buttons, etc. Very fast rebound to the original state.

When the product is in use, the silicone airbag (including the upper silicone balloon and/or the lower silicone balloon) will slowly leak and slightly deform the upper silicone balloon after being pressed; however, after the pressure is removed, the silicone balloon should be restored to its original state, which is excellent. The resilience will create a negative pressure inside the silicone balloon (the better the resilience, the greater the negative pressure), and the suction formed by the negative pressure will slowly return the gas outside the silicone balloon into the silicone balloon to complete the automatic inflation. The invention reduces the inflatable structure on the conventional air cushion, makes the air cushion structure very simple, the production cost is greatly reduced, and the service life is long;

The upper layer silicone balloon of the present invention has a wall thickness of 0.3 mm to 2 mm, a height of 3 mm to 50 mm, a volume of 100 mm 3 to 300,000 mm 3 , and a wall thickness of less than 0.3 mm. When the product is in use, the gas in the airbag overflows too fast, which may cause the product to be used for a short time so as to lose its use value. If the wall thickness of the airbag is greater than 2mm, although the single use time of the product can be very long, when the gas inside the airbag of the product overflows, the outer wall of the airbag is too thick, so that the external gas is difficult to enter the inside of the airbag, resulting in self-inflating of the product. The time is too long to be inflated quickly; because the inside of the airbag is kept at normal pressure, if the height of a single airbag is less than 3 mm or the volume is less than 100 cubic millimeters, the airbag may have insufficient internal air and no support. If the height of a single airbag is greater than 50 mm or larger than the volume 300000 cubic millimeters, because the airbag is too large, the resilience of the airbag after compression is not enough, and the self-inflating time of the product is too long, so that the product loses the application value. The self-inflating silicone airbag air cushion of the invention has a Shore hardness of 40 to 70 degrees, and the material of the hardness range has the best resilience. When the product is used due to insufficient air pressure inside the airbag, the excellent resilience will form a negative pressure inside. The gas outside the air bag is allowed to enter the inside of the air bag to complete the inflation process.

The substrate is provided with a through hole between each upper silicone airbag. When the air cushion has a convex upper silicone airbag on one side and a flat surface on the other side, the air cushion of the self-inflating silicone airbag is placed on the ground, and the air between the air cushion and the ground can be Quickly discharge from the through hole, so that the air cushion is not easy to slide on the ground, especially when used in the bathroom, water enters between the air cushion and the floor from the through hole, and the air between the air cushion and the floor is squeezed to make the air cushion and the floor The relative position is stronger and it is less prone to slippage, which ensures safety. A suction cup is arranged on one side of the air cushion on the air cushion. When the air cushion is used, the air cushion is pressed on the support surface such as the ground to discharge the air in the suction cup. Due to the elastic recovery of the air cushion, a vacuum is formed in the suction cup to ensure the air cushion and the ground. The support surface is firmly connected and not easy to move.

When the air cushion is respectively provided with an upper layer silicone airbag and a lower layer silicone airbag, an upper airflow passage is formed between each upper silicone airbag, and each lower silicone airbag forms a lower airflow passage communicating with the upper airflow passage through the through hole. When the human body is pressed onto the air cushion, the upper silicone airbag and the lower silicone airbag are both compressed and deformed. During the deformation of the air cushion, the airflow flows from the through hole to generate a feeling of breeze blowing, which makes the human body feel very comfortable when the human body is completely pressed. After the air cushion, the airflow on both sides of the substrate flows in the upper airflow passage, the through hole and the lower airflow passage, which increases the air permeability of the air cushion, so that the human body feels comfortable and cool, and is beneficial to health.

According to different market needs, the invention adjusts the wall thickness, height, volume and hardness of the silicon material to adjust the air permeability and the charging efficiency of the airbag, thereby meeting the practical needs of customers in different fields.

【detailed description】

The present invention is further described below in conjunction with the accompanying drawings:

Example 1:

As shown in FIG. 1 to FIG. 2, a self-inflating silicone airbag air cushion includes a silica gel substrate 1. The substrate 1 is provided with a plurality of upper and lower silicone airbags 2 which are independent and convex on one side, and the upper silicone airbag 2 The wall thickness is 0.3 mm to 2 mm, the height is 3 mm to 50 mm, and the volume is 100 mm 3 to 300,000 mm 3 . The hardness of the self-inflating silicone airbag cushion is 40 to 70 degrees Shore hardness. The substrate 1 is provided with a through hole 6 between each of the upper silicone airbags 2. When the self-inflating silicone airbag cushion is placed on the ground, the air between the air cushion and the ground can be quickly discharged from the through hole 6 to make the air cushion. It is not easy to slide on the ground, especially when used in the bathroom, water enters between the air cushion and the floor from the through hole 6, and the air between the air cushion and the floor is squeezed out, so that the relative position between the air cushion and the floor is stronger, and it is not easy to appear. Sliding ensures safety. The upper silicone balloon 2 is a hemisphere, and may have other shapes such as a square. Now all kinds of air cushions on the market are made of airtight rubber materials, but even if the rubber material is airtight, the pressure will increase with time and other factors. Slow air leak, because the rubber airbag can not inhale the gas to return to the original state after the gas leaks, so that the air cushion quickly loses its intended function, so those skilled in the art have been working hard to find a material with better air tightness (such as rubber). The material is used to manufacture the air cushion, and the inventors overcome the above-mentioned technical prejudice, and specially use the airtight silica gel to manufacture the air cushion, which solves the problem that the airbag leaks and then returns to the original state, because the silica gel and the rubber material have the essence. The difference: 1. Silica gel is obtained by gradually extracting silica (silica) which is abundant in nature. Rubber is basically obtained from petroleum (except natural rubber); 2. The molecular backbone of silica gel is the SI-O structure, and the main chain structure of the rubber is C-C structure (including natural gelatin). Therefore, the burning of silica gel is white smoke, and the burning of rubber is black smoke, which is very obvious. From the above two points, it can be seen that the silica gel and the rubber material are two different materials. The performance and characteristics are very different. The two materials have obvious essential differences in use and cannot be interchanged. Silicone is very breathable and far superior to rubber. Under the same conditions, the permeability of silica gel is generally more than 10 times that of rubber material. In addition, the rebound resilience of silica gel is very good. After compression, it can rebound very quickly to the original state. The upper silicone balloon 2 will leak slowly after being pressed. The air and the upper silicone airbag 2 are deformed, but after the pressure is removed, the upper silicone airbag 2 is restored to its original state, and its excellent resilience will form a suction force inside the upper silicone airbag 2, so that the gas outside the upper silicone airbag 2 slowly enters the upper layer again. In the silicone airbag 2, the inflation is completed, so in the process of using the self-inflating silicone airbag air cushion of the present invention, when the human body is pressed on the air cushion, the upper silicone airbag 2 is deformed. When the human body leaves the air cushion, the upper silicone airbag 2 self-inhales and returns to the original state. The inflatable structure on the traditional air cushion is reduced, the air cushion structure is very simple, the production cost is greatly reduced, and the service life is long; the upper silicone airbag 2 has a wall thickness of 0.3 mm to 2 mm, a height of 3 mm to 50 mm, and a volume of 100 cubic millimeters. Up to 300,000 cubic millimeters, if the wall thickness is less than 0.3mm When the product is in use, the gas in the airbag overflows too fast, which may cause the product to be used for a short time so as to lose its use value. If the wall thickness of the airbag is greater than 2mm, although the single use time of the product can be very long, when the gas inside the airbag of the product overflows, the outer wall of the airbag is too thick, so that the external gas is difficult to enter the inside of the airbag, resulting in self-inflating of the product. The time is too long to be inflated quickly; and because the inside of the airbag is kept at atmospheric pressure, if the height of a single airbag is less than 3 mm or the volume is less than 100 cubic millimeters, the airbag may have insufficient internal air and no support, if the height of a single airbag is greater than 50 mm or volume If it is larger than 300,000 cubic millimeters, the airbag will be too large, resulting in insufficient resilience after compression of the airbag. The self-inflating time of the product is too long, so that the product loses its application value. In addition, the self-inflating silicone airbag cushion has a Shore hardness of 40 to 70 degrees, and the material in this hardness range has the best resilience. When the product is used due to insufficient air pressure inside the airbag, its excellent resilience will form a negative pressure inside, so that The gas outside the air bag enters the inside of the air bag to complete the inflation procedure. Further, the upper layer of the silicone airbag 2 has a wall thickness of 0.4. Mm~1.5mm, height 5mm~30mm, volume 200mmmm to 100000m3. More preferably, the upper layer of the silicone airbag 2 has a wall thickness of 0.6. The mm~1.2mm, the height is 8mm~20mm, and the volume is 400mmmm to 20,000cm. The upper silicone airbag 2 has the best self-inflating and self-rebound characteristics in the above size range.

Due to the elastic recovery of the air cushion, a vacuum is formed in the suction cup 7, so that the air cushion is firmly connected to the support surface such as the ground and is not easily moved.

Example 3:

As shown in FIG. 5 to FIG. 7, the difference between Embodiment 3 and Embodiment 1 is:

The other surface of the substrate 1 is provided with a plurality of lower-layer silicone airbags 3 which are independent of each other and are in contact with the upper silicone airbag 2, and the lower silicone airbag 3 has a wall thickness of 0.3 mm to 2 mm and a height of 3 mm to 50 mm. a volume of 100 cubic millimeters to 300,000 cubic millimeters, an upper airflow passage 5 is formed between each of the upper silicone airbags 2, and a lower airflow passage 4 communicating with the upper airflow passage 5 through the through holes 6 is formed between each of the lower silicone airbags 3, The lower silicone balloon 3 described above has a hemisphere or other shape such as a square. When the human body is pressed onto the air cushion, the upper silicone airbag 2 and the lower silicone airbag 3 are both compressed and deformed. During the deformation of the air cushion, the airflow flows from the through hole 6 to generate a feeling of breeze blowing, so that the human body feels very comfortable when the human body After being completely pressed into the air cushion, the airflow on both sides of the substrate 1 flows in the upper airflow passage 5, the through hole 6 and the lower airflow passage 4, which increases the air permeability of the air cushion, so that the human body feels comfortable and cool, and is beneficial to health. Further, the underlying silicone balloon 3 has a wall thickness of 0.4. Mm~1.5mm, height 5mm~30mm, volume 200mmmm to 100000m3. More preferably, the underlying silicone balloon 3 has a wall thickness of 0.6. The mm~1.2mm, the height is 8mm~20mm, the volume is 400mmmm to 20,000cm3, and the lower silicone airbag 3 has the best self-inflating and self-rebound characteristics in the above size range.
