Description

Technical Field

[0001] The invention relates to the technical field of cooling pillows, and more particularly to a ventilated support cavity cooling pillow with an airflow noise reduction structure. Background Art

[0002] When people sleep, their heads are in contact with the pillow. As sleep goes on for a long time, the head resting on the pillow for a long time will make the space between the head and the pillow become stuffy and humid, thus affecting the quality and experience of sleep.

[0003] The current ventilation pillows have the following main disadvantages:

[0004] 1. The supporting structure inside the pillowcase will cause poor ventilation due to its density, such as ventilated pillows with fan cotton, memory foam, etc. as the supporting structure;

[0005] 2. The supporting structure inside the pillowcase is either too rigid or too weak, or has an unreasonable shape and structure, which will cause a lack of comfort;

[0006] 3. With existing ventilated pillows, when the fan blows air on the pillow, the airflow will cause a lot of noise, which will reduce the sleep quality and fail to provide a good sleep guarantee.

[0007] For example, Chinese patent document: CN 214595180U, publication date: 2021.11.05, discloses a cushioning pad, which includes a ventilation layer and a breathable elastic layer, wherein the elastic layer covers the ventilation layer; the ventilation layer is a mesh structure, and a heat sink is provided on the ventilation layer; a mounting hole is provided on the ventilation layer, and the heat sink is embedded in the mounting hole, the material of the ventilation layer is thermoplastic polyester elastomer, and the inner wall of the mounting hole is interference fit with the heat sink; the cushioning pad is a seat cushion, a back cushion or a pillow, and when the cushioning pad is a seat cushion, the side of the ventilation layer on which the heat sink is installed is placed on the rear side of the seat.

[0008] In the ventilation layer of the thermoplastic polyester elastomer in this technical solution, wind cannot flow smoothly inside it, and the ventilation effect is not ideal.

[0009] Chinese patent document: CN 104622141A, publication date: 2015.05.20, discloses a pillow with fanning function, and a speed-adjustable micro fan which can deliver cyclone into the pillow when powered on, and the airflow flows out from the mesh holes of the pillow, which can play the role of ventilation, heat relief, hypnosis and health care.

[0010] The mesh plate in this technical solution is made into a hollow square main body, which has a relatively high structural strength. However, the hollow square main body does not conform to the structure of the physiological curve of the human head, shoulders and neck, thus resulting in a lack of comfort.

[0011] Chinese patent document: CN 210204263 U, publication date: 2020.03.31, discloses a source connected, a fan is arranged in the inner cavity of the bracket, an air inlet is arranged on the side of the bracket, the top of the bracket is an air outlet opening, and a mesh belt that can lean against the user's head is arranged on the air outlet opening. The fan blows the air entering from the air inlet out of the pillow through the gaps in the mesh belt.

[0012] In this technical solution, the fan is arranged in the inner cavity of the bracket without airflow buffering, which will cause huge vibration and noise, resulting in a decline in sleep quality and failure to provide a good sleep guarantee.
