Description

Technical Field

[0001] The utility model relates to the technical field of household articles, in particular to a bread pillow core with adjustable length. Background Art

[0002] A pillow is a bedding used to support the head during sleep, usually filled with soft materials such as cotton, down, memory foam, latex or other synthetic materials, and wrapped in a cloth cover for people to use comfortably; existing pillows are usually fixed in size and suitable for use by one person alone.

[0003] However, in family life, when couples, lovers or parents sleep with their children, they sometimes need to sleep closer together. At this time, sharing a pillow will result in the pillow being not long enough for two people to share. Multiple pillows arranged in sequence or with overlapping edges will result in an uneven surface, which will seriously affect sleep.

[0004] Therefore, a pillow with adjustable length is needed according to usage requirements. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an adjustable-length bread pillow core which is simple, efficient, safe, reliable and easy to operate by embedding the two ends of the inflatable pillow core into the inner tube of the inflatable pillow core and adjusting the length of the bread pillow core through a limiting ring and a limiting belt.

[0006] The utility model is realized through the following technical scheme, providing a bread pillow core with adjustable length, including an inflatable pillow core, the inflatable pillow core is a tubular structure, and an inflation valve is provided on the inflatable pillow core, and the outer surface of the inflatable pillow core is covered with a pillowcase; by embedding the two ends of the inflatable pillow core into the inner tube of the inflatable pillow core, the length of the bread pillow core is adjusted by a limiting ring and a limiting belt.

[0007] As an optimization, the inflatable pillow core includes a plurality of air bags A connected in sequence, and an inflation valve is provided on each air bag A. The position of the gas in the inflatable pillow core is limited by the plurality of air bags A connected in sequence to prevent the inflatable pillow core from deforming at will.

[0008] As an optimization, the airbag A extends axially along the inflatable pillow core, and the airbags A are connected in sequence along the circumference of the inflatable pillow core; the airbag A extending axially along the inflatable pillow core plays a certain supporting role on the middle part of the inflatable pillow core.

[0009] As an optimization, the airbag A extends around the axis of the inflatable pillow core, and the airbags A are connected in sequence along the axial direction of the inflatable pillow core; the airbags A extending around the axis of the inflatable pillow core prevent gas from flowing to both sides of the inflatable pillow core.

[0010] As an optimization, the inflation valve is a one-way check valve with its opening facing the inside of airbag A, and the inflation valve is connected to an inflation nozzle in turn; each airbag A is inflated simultaneously through the inflation nozzle and the inflation valve to ensure that the air pressure inside each airbag A is the same, thereby preventing the inflatable pillow core from being deformed due to different air pressures, thereby affecting sleep.

[0011] As an optimization, an exhaust valve is provided on the airbag A. The exhaust valve is a one-way check valve with its opening facing the outside of the airbag A. The exhaust valve is connected to an exhaust nozzle in turn. Each airbag A is exhausted at the same time through the exhaust nozzle and the exhaust valve, making exhaust more convenient.

[0012] As an optimization, airbags B extending along the circumference of the inflatable pillow core are provided at both ends of the inflatable pillow core, and airbags B are provided with valve nozzles; separate supporting forces are applied to the two ends of the inflatable pillow core through airbags B to prevent the two ends of the inflatable pillow core from being unable to support the head due to the gas flow in airbags A.

[0013] The beneficial effects of the utility model are as follows: by embedding the two ends of the inflatable pillow core into the inner tube of the inflatable pillow core, the length of the bread pillow core is adjusted by the limiting ring and the limiting belt; the position of the gas in the inflatable pillow core is limited by a plurality of air bags A connected in sequence to prevent the inflatable pillow core from deforming at will; the air bags A are inflated at the same time by the inflation nozzle and the inflation valve to ensure that the air pressure in each air bag A is the same to prevent the inflatable pillow core from deforming due to different air pressures, thereby affecting sleep; the air bags A are exhausted at the same time by the exhaust nozzle and the exhaust valve to make exhaust more convenient; a separate supporting force is applied to the two ends of the inflatable pillow core by the air bag B to prevent the two ends of the inflatable pillow core from being unable to support the head due to the flow of gas in the air bag A.
