Description

Pneumatic height-adjustable backrest connecting pillow

Technical Field

The utility model belongs to bedding, in particular to a pneumatic adjusting pillow and a backrest connecting pillow with the height of the backrest.

Background

In a long life, the sleep occupies one third of the life, so that one third of the sleep time of a person is spent in bed, the pillow is an indispensable tool in bed, and the sleep quality of the person is directly influenced by the height of the pillow. Ancient people say that sleeping is the most enjoyable life, and the three essences of health preservation say: "sleeping" is the most enjoyable life. Ancient people have a word: the immortal foraging sleeping party … … has the effect of sleeping enough, is refreshing, not less than invisible people, and is important for people how much sleep is. The height and hardness of the pillow directly affect the sleeping quality and the health of people. People can feel in person, the pillow is higher and comfortable when sleeping, and is lower and comfortable when sleeping, and the height difference of the pillow needed is larger when people lie on side and lie on back due to the difference of the head-shoulder distances. However, the pillows used by us at present are uniform and different in size, and the comfort level does not meet the demand of us at will. Sometimes, the user feels dizziness, neck ache and uncomfortable feeling when sleeping in the morning at night. Sometimes, after waking up, people find that the neck cannot be moved and bounced, and only one posture can be kept, which is commonly called as the stiff neck, and the stiff neck is the expression of acute dislocation of the cervical vertebra, and all the phenomena are caused by improper pillow, so that the pillow with the height capable of being adjusted randomly is the requirement of sleeping of a human body. When the user does not sleep, the user sometimes sits on a bed to rest, and also needs a proper backrest when the user rests on the bed, the backrest is different from one person to another, the backrest is different in requirements, sometimes high or low, and therefore the backrest with the height capable of being adjusted at will is the requirement when the user rests on the bed. The pillow and the backrest are combined into a whole, and the height of the backrest is adjustable and the backrest is connected with the pillow, so that the pillow is convenient and practical and becomes the best choice.

The patent office discloses a height-adjustable pillow, which is published under the publication number CN209391581, wherein a motor transmission rod rotates to drive a telescopic rod to stretch and retract, and a supporting plate is driven to move up and down, so that the height of the pillow is adjusted, and the requirement of a human body is met. It can be seen that the pillow has a complex structure, is provided with a motor and a plurality of mechanical rotating parts, has impractical thickness and hardness, and does not have the function of a backrest.

The patent office also discloses another patent "back pillow", publication No. CN108601456, in which the back is comfortable to use, but too high as a pillow and cannot be adjusted, so it is not comfortable to use.

In hot weather in summer or when having a fever and a cold, people's head cooling can make whole health temperature descend, can make the brain become clear, uses ice cap to patient in the hospital also this reason, also has in ancient times to pour into cold water into the porcelain pillow and make the way of head cooling. The backrest and the pillow disclosed above have no refrigeration function.

Therefore, the conjoined pillow which is made of natural rubber, has the height adjusted by the air pressure and has the refrigeration function and is connected with the backrest into a whole, is convenient and practical and is certainly popular with users.
