Polyurethane batting

Abstract

This application discloses a polyurethane pouch, belonging to the field of polymer material technology. It includes an outer shell with a functional cavity in the middle, the cavity being an open structure. A breathable layer is sewn into the middle of the outer shell at the functional cavity, and a moisture-absorbing layer is inserted inside the breathable layer. A heating wire assembly is fixedly installed inside the moisture-absorbing layer. Several sets of ventilation holes are formed on the outer periphery of the breathable layer. An upper mounting cavity and a lower mounting cavity are formed inside the outer shell. The upper mounting cavity is located above the breathable layer, and the lower mounting cavity is located below it. The upper mounting cavity is filled with an upper polyurethane core, and the lower mounting cavity is filled with a lower polyurethane core. This application enhances the evaporation of moisture inside the outer shell and the evaporation of moisture in the moisture-absorbing layer, restoring the moisture-absorbing capacity of the layer. Simultaneously, moisture is discharged through the ventilation holes, which helps keep the inside of the polyurethane pouch dry and maintains user comfort.

Description

Technical Field

[0001] This application relates to the field of polymer materials technology, and in particular to a polyurethane cotton pack. Background Technology

[0002] Polyurethane foam pillows, also known as memory foam pillows, utilize slow rebound properties to adjust their shape according to body temperature and pressure, precisely conforming to the curves of the head and neck, effectively dispersing pressure points, and relieving cervical fatigue. They are especially suitable for people with cervical discomfort or those who prefer to sleep on their side, as they can reduce muscle tension during sleep.

[0003] In actual use, in environments with poor ventilation and high humidity, the polyurethane foam pack is prone to becoming damp and moldy due to its porous structure and high water absorption. It may also emit an unpleasant odor, affecting the user's experience and potentially posing a threat to the user's health.

[0004] Therefore, this application provides a polyurethane foam pack. Utility Model Content To address the shortcomings of existing technologies, this application provides a polyurethane foam pack that overcomes these deficiencies. The purpose is to solve the problem that, in practical use, in environments with poor ventilation and high humidity, the polyurethane foam pack's porous structure and high water absorption cause it to easily become damp and moldy, emitting unpleasant odors, affecting the user experience, and potentially posing a health threat.

[0006] By adopting the above technical solution, the upper and lower polyurethane cores provide good support during use. The functional cavity is located in the middle of the outer cover, creating an air circulation channel. The moisture-absorbing layer enhances the absorption of moisture inside the outer cover, and the ventilation holes enhance ventilation of the moisture-absorbing layer, thereby promoting moisture removal. In humid weather, the heating wire group inside the moisture-absorbing layer can be activated to enhance the evaporation of moisture inside the outer cover and the moisture in the moisture-absorbing layer, restoring the moisture-absorbing capacity of the layer. At the same time, moisture is discharged from the ventilation holes, which helps to keep the inside of the polyurethane padding dry and maintain user comfort.

[0007] As a preferred technical solution of this application, a zipper is sewn on the outer periphery of the breathable layer, and the zipper is C-shaped.

[0008] By adopting the above technical solution, the moisture-absorbing layer can be easily maintained by unzipping the zipper, thus improving its practicality during use.

[0009] As a preferred technical solution of this application, an electrical connector is fixedly installed on one side of the breathable layer, and the electrical connector is electrically connected to the heating wire assembly.

[0010] By adopting the above technical solution, the heating wire assembly can be turned on and off by connecting to an external power source via an electrical connector, thus improving the portability of controlling the heating wire assembly.

[0011] As a preferred technical solution of this application, an activated carbon layer is fixedly installed on the side of the upper polyurethane core and the lower polyurethane core near the outer jacket, and the activated carbon layer is fixedly installed with the outer jacket.

[0012] By adopting the above technical solution, the odors inside the upper and lower polyurethane cores are adsorbed through the adsorption effect of the activated carbon layer, further improving the practicality during use.

[0013] As a preferred technical solution of this application, a neck support is fixedly connected to the top of the outer garment.

[0014] By adopting the above technical solution, the thickness of the neck area is increased by the neck support, which provides better support for the cervical spine and better relieves cervical fatigue.

[0015] As a preferred technical solution of this application, the top of the coat is provided with a headrest area, and the top of the coat is provided with a number of ventilation holes in the middle of the headrest area.

[0016] By adopting the above technical solution, the ventilation holes promote heat dissipation in the headrest area, reducing sweating and discomfort caused by stuffiness of the head, and helping to keep the upper and lower polyurethane cores dry.

[0017] As a preferred technical solution of this application, the outer garment is made of spring spun fabric.

[0018] By adopting the above technical solution, the spring spun fabric has excellent breathability and durability, and is easy to clean and maintain, thus improving its practicality in use.

[0019] The beneficial effects of this application are: 1. During use, the upper and lower polyurethane cores provide good support. The functional cavity is located in the middle of the outer cover, creating an air circulation channel. The moisture-absorbing layer enhances the absorption of moisture inside the outer cover, and the ventilation holes enhance ventilation of the moisture-absorbing layer, thereby promoting the expulsion of moisture. In humid weather, the heating wire group inside the moisture-absorbing layer can be turned on to enhance the evaporation of moisture inside the outer cover and the moisture in the moisture-absorbing layer, restoring the moisture-absorbing capacity of the layer. At the same time, moisture is discharged from the ventilation holes, which helps to keep the inside of the polyurethane padding dry and maintain the comfort of use.
