Description

Technical Field

[0001] The utility model belongs to the technical field of bedding products, and particularly relates to a liquid-injected gravity blanket. Background Art

[0002] A gravity blanket can apply 7-13% of body weight to a human body during sleep. This deep pressure stimulation (DPS) can reduce sympathetic nerve excitability and promote parasympathetic nerve excitability, so that the body can quickly calm down, thereby producing a calming effect, reducing body alertness, relieving stress, and ultimately promoting sleep. However, most gravity blankets on the market currently use glass beads, ceramic beads, natural stone beads, etc. as the weight layer. For example, the gravity blanket disclosed in the patent document CN217610376U "A New Gravity Blanket" uses weight beads for weighting, but the weight beads will produce noise when they collide with each other, which will affect sleep to a certain extent. The impact sound can be avoided if the blanket is filled with liquid. For example, the patent document with document number CN213030390U "A Gravity Blanket with Adjustable Gravity" provides pressure by setting a water bag and injecting water into the water bag. However, due to the low density of water, a larger volume is often required to achieve appropriate weight distribution, which leads to a larger overall volume or thickness of the blanket, making it inconvenient to carry and use in daily life. In addition, the liquid in the water bag still has a certain sloshing sound of the liquid, and its noise reduction effect is not obvious. Utility Model Content
