Description

Pocket spring assembly and pillow Technical Field The application relates to the technical field of bedding, in particular to a bagged spring assembly and a pillow. Background Pillow products in the current market mainly comprise latex pillows, memory cotton pillows and bagged spring pillows. The latex pillow is made of natural latex or synthetic latex as pillow core material, and the memory cotton pillow is made of polyurethane foam, and has linear viscoelastic property. The latex pillow and the memory cotton pillow have only single linear rigidity, and can not simultaneously meet the two contradictory requirements of initial soft fit and deep compression support. In the related art, a bag spring pillow commonly adopts an equal pitch spring. The mechanical property of the equal-pitch spring is single linearity, namely the spring constant K of the equal-pitch spring is always unchanged from the first millimeter to the last millimeter, the equal-pitch spring can only provide linear support in the whole process, and the rigidity cannot be automatically adjusted according to the compression depth. When a user sleeps on the side of the bagged spring pillow in the related technology, the weight of the head of the user is concentrated in a small area, the condition that all rings are closed easily occurs to the equal-pitch spring, so that the user generates obvious bottom touch feel, and the sleeping quality and the cervical vertebra support of the user are seriously affected. Disclosure of Invention In order to solve or partially solve the problems in the related art, the application provides a bagged spring assembly and a pillow, which can meet the supporting requirements under different sleeping postures and improve the sleeping experience of a user. The application provides a bagged spring assembly, which comprises a spring body and a wrapping bag, wherein the spring body is an unequal-pitch spring, the spring body comprises a first circle segment and a second circle segment, one end of the first circle segment is connected with one end of the second circle segment, the first circle segment is positioned above the second circle segment, the first circle segment is provided with a first pitch, the second circle segment is provided with a second pitch, the second pitch is larger than the first pitch, the overall rigidity of the spring body is changed in a step mode when the first circle segment is subjected to axial pressure to reach a closed circle state, and the wrapping bag wraps the spring body. Further, the ratio of the second pitch to the first pitch is 1.5-3. Further, the effective number of turns of the spring body is 4-8, wherein the effective number of turns of the first circle segment is 2-4, and/or the effective number of turns of the second circle segment is 2-4. Further, two opposite ends of the spring body are respectively pressed against the wrapping bags and are in a precompressed state, and in the precompressed state, the compression amount of the spring body is 20-40% of the free height of the spring body.
