Description

Technical Field

[0001] The present application relates to the technical field of bedding products, and in particular to a detachable multifunctional bunk mattress. Background Art

[0002] Mattresses are an everyday household item that is used for a long time in every household. In order for people to get a good sleep, mattresses are an indispensable product on the market. Although there are many types of mattresses with various materials, qualities, styles and functions on the market, and mattresses on the market can solve the sleep problems of most people, the current development of mattresses still lacks a mattress that can be used by customers in both winter and summer, can adjust the softness and hardness of the mattress, can be easily disassembled for storage or transportation, and can be easily cleaned. The mattresses in the existing technology have a single function, and when customers use them, the functions of the mattresses are complicated or difficult to achieve.

[0003] For example, a Chinese patent application numbered 200820212374.X, filed on September 26, 2008, is titled "Externally Split Combination Mattress." The patent's technical solution is as follows: an externally split combination mattress comprising a mattress core and a top pad. The mattress core is provided with a zipper, and the top pad is also provided with a zipper: the zipper on the mattress core is compatible with the zipper on the top pad. Adjacent mattress cores are provided with cooperating zippers; the top pad is provided with a zipper around each side, and the mattress core is provided with a zipper around each side that is compatible with the zipper on the top pad. The zippers around each side of the mattress core are connected to the zippers around each side of the mattress core to form a complete mattress. The top pad includes a soft top pad and a hard top pad, providing both soft and hard functions, allowing for adjustment according to personal preference.

[0004] Although the above patent realizes the combination disassembly and softness and hardness adjustment functions of the mattress, the above patent has the following shortcomings: First, the softness and hardness adjustment function is difficult to realize. The soft pad and the hard pad are respectively arranged on the upper top surface and the lower bottom surface of the mattress core. When the customer wants to realize the softness and hardness adjustment function, the soft pad and the hard pad need to be disassembled and then installed according to the customer's softness and hardness requirements. Since the mattress core itself is heavy and the disassembly and installation methods are complicated, the softness and hardness adjustment function is difficult to realize and extremely inconvenient to use; secondly, the mattress is provided with a plurality of zipper disassembly and combination methods as a whole, and the mattress core is also provided with a zipper disassembly and combination method of the mattress core. Although it is convenient for transportation, the design of the zipper is unreasonable and the disassembly method is too complicated; finally, the above patent has a single function and only realizes the combination disassembly and softness and hardness adjustment functions, and cannot achieve the effect of keeping the mattress clean and hygienic and the mattress being used in both winter and summer.
