Description

Technical Field

[0001] This application relates to an airbag - type multifunctional pillow and its manufacturing method, belonging to the technical field of pillows. Background Art

[0002] With the rapid development of society, most people are in a sub - healthy state. This is mainly related to the significant decline in sleep quality caused by increased social pressure and changes in eating habits, which are subtly changing people's health status. Among them, eating habits can be adjusted and improved during daily diet, while the low sleep quality, like an "invisible hand", needs to be improved from sleeping. Therefore, nowadays people have higher and higher requirements for the functions of pillows. Not only do they need it to conform to the human body, but more importantly, they need the pillow to have the function of conveniently adjusting the height, so as to better relieve the pressure on the human head and neck and improve sleep quality.

[0003] Airbag - type pillows can adjust the height, and during sleep, the height of the pillow is always consistent with the depth of the cervical physiological curve, so that the neck muscles and ligaments can be fully relaxed, which is beneficial to human health. Currently, most airbag - type pillows are composed of an airbag and a pillow core. The airbag is embedded in the pillow core, with stable support effect and can effectively reduce the noise generated by gas flow. However, since the airbag and the pillow core are not completely fitted, the support strength of each part of the pillow is uneven during the inflation and deflation process; in addition, after long - term use, dirt and grime are likely to accumulate in the gap between the airbag and the pillow core, increasing the risk of bacterial growth, thus leading to a decline in sleep quality. Summary of the Invention

[0004] To solve the above problems, an airbag - type multifunctional pillow and its manufacturing method are provided, which can make the support strength of each part of the pillow uniform, reduce local pressure, improve the comfort of the human head and neck, and can prevent bacterial growth, which is beneficial to human health and ensures sleep quality.

The airbag multifunctional pillow reduces the pressure on the head and neck during sleep, relieves cervical fatigue, and improves sleep quality by providing precise support and intelligent adjustment.

[0027] 2. The manufacturing method of the airbag type multi-functional pillow of the present application. A suitable aging process is beneficial to the diffusion of compounding agents in latex, and there will be no phenomena of air bubbles and collapsed bubbles during molding, and it plays a certain pre-vulcanization role, reducing the shrinkage rate of the prepared sample and improving the mechanical properties; using ammonium sulfate and sodium fluorosilicate together can improve the resilience of the latex foaming material and improve the cell structure; high-speed foaming and low-speed bubble homogenization can reduce the large bubbles generated during the foaming process and increase the uniformity of the cells; a suitable gelling process can ensure that the cell structure is fixed after foaming and homogenization, prevent the cells from merging and collapsing after foaming, and ensure the cell morphology before injection molding; zinc oxide not only acts as an activator of the vulcanizing agent to promote vulcanization and curing, but also can cooperate with ammonium sulfate to promote the gelling of the latex foam. By optimizing processes such as aging, foaming, homogenization, gelling, and vulcanization, a pillow body with small permanent deformation, high resilience, and excellent mechanical properties is obtained, and the first folding airbag and the second folding airbag are respectively installed on the headrest part and the neckrest part through magic stickers. On the one hand, it can be adjusted by inflating and deflating according to user needs to ensure that the pillow always provides the best support. On the other hand, it is convenient for users to disassemble, improving the flexibility and convenience of use.

[0028] 3. The manufacturing method of the airbag type multi-functional pillow of the present application. The aldehyde group on cinnamaldehyde can react with the amino group on carboxymethyl chitosan to form a Schiff base reaction, thereby enhancing the mechanical properties of carboxymethyl chitosan. At the same time, the formed gel network can be used to load and stabilize lignin. There is a hydrogen bond interaction between the cross-linked network of cinnamaldehyde / carboxymethyl chitosan and the lignin structure, so that lignin can be effectively dispersed. Lignin, carboxymethyl chitosan, and cinnamaldehyde in this composite antibacterial agent all have antibacterial properties, and they are all of natural origin, have good compatibility with latex materials, can cooperate to antibacterial, prevent the growth of bacteria, and can slowly release active ingredients to achieve long-term antibacterial, thus effectively extending the service life of the airbag type multi-functional pillow.

[0037] As Figures 1-3 shown, the present application provides a multi-functional airbag pillow, including a pillow body. The pillow body includes an integrally formed headrest part 1 and neckrest part 2, which are used to support the head and neck respectively, improving the comfort of use; a first folding airbag 3 is embedded in the headrest part 1, and a second folding airbag 4 is embedded in the neckrest part 2.

The first connecting part 6 and the second connecting part 8 are provided with a hook surface 9 of Velcro, and the first folding part 5 and the second folding part 7 are provided with a loop surface 10 of Velcro that connects to the hook surface 9 of Velcro, ensuring that the airbag remains stable during the inflation and deflation processes, avoiding displacement, so that the support strength of each part of the pillow is uniform, and at the same time, it is convenient to disassemble and assemble, improving the practicality of the pillow;

[0038] Pressure sensors 11 are provided at the tops of the first folding airbag 3 and the second folding airbag 4, and inflation and deflation assemblies are provided at the bottoms of the first folding airbag 3 and the second folding airbag 4. The pressure sensors 11 are electrically connected to the inflation and deflation assemblies, realizing real-time monitoring and automatic adjustment of the support strength of the head and neck, reducing the pressure on the cervical vertebrae and the head, and providing a comfortable sleep experience for users.

[0039] Further, the inflation and deflation assembly includes an air tube 12, an air pump 13, and a control valve 14. One end of the air tube 12 is connected through the bottom of the first folding airbag 3 and the second folding airbag 4, and the other end is connected to the air pump 13. The control valve 14 is communicatively disposed on the air tube 12. The air pump 13 inflates or deflates the airbag through the air tube 12, and the control valve 14 precisely regulates the air flow to ensure that the airbag can quickly and stably reach the target pressure, improving the user experience.

[0040] Further, a main control circuit board 15 is provided inside the air pump 13. The main control circuit board 15 is electrically connected to the pressure sensor 11. The main control circuit board 15 can receive the data of the pressure sensor 11 in real time, precisely adjust the inflation and deflation operations of the air pump 13, dynamically adjust the airbag pressure, and ensure that the pillow always provides the best support.

[0041] Further, a conversion module for inflation and deflation is installed inside the control valve 14. The conversion module includes an inflation valve 16 and a deflation valve 17. The main control circuit board 15 is electrically connected to the inflation valve 16 and the deflation valve 17 respectively. The main control circuit board 15 can intelligently switch the working states of the inflation valve 16 and the deflation valve 17 according to the data of the pressure sensor 11, quickly adjust the airbag pressure, and ensure that the height and hardness of the pillow always adapt to the user's needs.

[0042] When pressure is applied to the top of the first folding airbag 3 and / or the second folding airbag 4, the pressure sensor 11 transmits a piezoelectric signal to the main control circuit board 15. The main control circuit board 15 analyzes the piezoelectric signal and drives the inflation and deflation assembly to work. During inflation, the conversion module on the control valve 14 rotates to connect the inflation valve 16 to the air tube 12, and the air pump 13 works to transport gas into the first folding airbag 3 and / or the second folding airbag 4. When the pressure sensor 11 senses the disappearance of pressure and deflation is required, the conversion module on the control valve 14 rotates to connect the deflation valve 17 to the air tube 12, the air pump 13 stops working, and the gas in the first folding airbag 3 and / or the second folding airbag 4 is released.

[0043] During the working process of this airbag multi-functional pillow, the air pump 13 provides a gas source and transports gas to the first folding airbag 3 and the second folding airbag 4 through the air tube 12. The pressure sensor 11 continuously detects the pressure of the first folding airbag 3 and the second folding airbag 4 and transmits the signal to the main control circuit board 15. The main control circuit board 15 analyzes the signal according to the preset logic and issues a control command to drive the opening and closing of the inflation valve 16 or the deflation valve 17, thereby realizing the adjustment of the air pressure in the first folding airbag 3 and the second folding airbag 4 to adapt to the depth of the cervical physiological curve, enabling the human body to be fully relaxed and conducive to improving sleep quality.

[0044] In this application, the preset logic in the main control circuit board 15 is prior art and will not be described in detail here.
