With the continuous improvement of people's material living standards, more and more people begin to pay attention to their quality of life. Sleep accounts for one third of people's life. The four piece mattress on the bed is an indispensable household product in people's daily life. With the continuous improvement of people's living standards, people have higher and higher requirements for the appearance, functionality, environmental protection characteristics and product quality of mattresses. Now, the development of mattresses is also developing in the direction of three-dimensional and multi-function. In the prior art, mattresses are generally divided into spring mattresses, palm mattresses, latex mattresses, water mattresses and air mattresses.
Four piece bed set
Among these four piece bed mattresses, spring mattresses are commonly used. A spring layer is arranged inside the spring mattress, and a suitable filling layer is arranged on the spring layer. However, with long service time, the spring is easy to rust and elastic failure. The overall structure of the existing mattress is also difficult to meet the needs of different uses, which limits the application of the existing Simmons mattress. At present, there are many mattresses on the market, but spring mattresses and pure sponge mattresses are mattresses with fixed hardness; If consumers feel uncomfortable after buying home, they can't adjust.
In view of the shortcomings of the prior art, the technician provides a four piece mattress with adjustable hardness. The mattress with adjustable hardness comprises an inflatable bag layer, an inflatable chestnut and a control device. The control device is arranged on the pipeline connecting the inflatable bag layer and the inflatable chestnut, including an air control valve and an external input response circuit; The external input response circuit is respectively connected with the air control valve and the inflatable chestnut; The external input response circuit controls the operation of the inflatable chestnut; In response to the control of the external input response circuit, the air control valve connects the inflatable bag layer with the inflatable chestnut. When the inflatable chestnut is opened, inflate the inflatable bag layer, or connect the inflatable bag layer with the outside to deflate the inflatable bag, or close the communication pipe of the inflatable bag layer to seal the inflatable bag layer, so as to realize the soft and hard adjustment of the mattress.
The inflatable bag layer comprises a left air bag and a right air bag; The left air bag and the right air bag are respectively connected with the inflatable chestnut through an air control valve, and both air control valves are connected to the same external input response circuit. It also includes a top sponge, a side bar sponge and a bottom support sponge. The inflatable bag layer is arranged in the space surrounded by the top sponge, the side rail sponge and the bottom support sponge. The hardness of the top sponge is less than that of the side bar sponge, and the hardness of the side bar sponge is less than that of the bottom support sponge. The surface of the bottom support sponge in contact with the inflatable bag layer is arranged in a wave shape.
Four strip protrusions are arranged around the top surface of the left air bag and / or right air bag of the four piece set on the bed to form a frame like support, and a plurality of strip protrusions are continuously arranged in the width direction of the area surrounded by the frame like support to form a sitting surface support. It also includes a handheld remote control device wirelessly connected with an external input response circuit; The handheld remote control device is used to start the external input response circuit, send control information to the external input response circuit according to the external input information, and receive the feedback information of the external input response circuit. The handheld remote control device has a keyboard assembly or touch screen, which is used to obtain external input information. The handheld remote control device has a display screen, which is used to display external input information and feedback information.
Compared with the prior art, the mattress with adjustable hardness has the following beneficial effects: the mattress with adjustable hardness has the advantage that consumers can select the required mattress hardness according to their personal habits to achieve good comfort. And it is divided into left and right mattresses. Two people lying on the mattress can adjust the soft and hard relatively independently according to their habits.
