Referring to fig. 1 to 3, an embodiment of the present invention provides a mattress with adjustable hardness, which can be applied to bed and chair products, and can also be used in the fields of medical spine correction body plasticity, etc. The soft and hard adjustable mattress and chair cushion comprises a mattress body 10, an air pressure device 20, a human physiology detection device 30 and a controller 40. The mattress body 10 comprises a support plate 11, contact air bags 12 which are sequentially arranged on the support plate 11 in the direction from the head to the tail of the bed and can sense whether the contact air bags are squashed or not, and a comfort layer 13 laid on the contact air bags 12. The gas pressure device 20 includes a gas pump 21 for supplying pressure gas to the contact airbags 12, electromagnetic gas valves 22 connected to the contact airbags 12 in one-to-one correspondence, gas pressure detectors 23 communicated with interfaces of the respective electromagnetic gas valves 22, and exhaust electromagnetic valves 24 communicated with the gas pressure detectors 23. The human physiology inspection apparatus 30 is used to inspect whether the human body 1 lying on the comfort layer 13 has a body motion. The controller 40 is used for operating the air pressure device 20 when the human physiology detecting device 30 detects a body motion.
When the human physiology inspection device 30 detects the body movement of the human body 1, the air pressure device 20 can inflate the non-squashed contact airbag 12, so that the supporting force of the corresponding area to the human body 1 is increased, and the hardness of the supporting part is enhanced. The hardness of the mattress body 10 at different positions is adjusted, so that the supporting force of the contact air bags 12 on different areas of the human body 1 is uniformly distributed. For example, the contact airbag 12 corresponding to the waist C of the human body 1 senses the non-squashed state, and the contact airbag 12 corresponding to the hip D adjacent to the back B of the waist C senses the squashed state, and at this time, the air pressure device 20 inflates the contact airbag 12 corresponding to the waist C, so that the contact airbag 12 region corresponding to the waist C has a large supporting force for the human body, and the hardness is increased. The adjustable-hardness mattress has the advantages of simple structure and low cost, and the condition that the existing mattress is high in cost due to the fact that more pressure sensing elements are arranged is avoided.
It should be noted that the human physiology detecting device 30 belongs to the prior art, and the human physiology detecting device 30 can detect the vital signs of the human body 1, and can also be used for detecting the body movement condition of the human body 1 during the sleeping process. For example, the existing Body Area Network (BAN for short, chinese name is human Body center Network). The automatic operation of the pneumatic device 20 is triggered according to each body movement of the human body 1. The pressure of each contact point air bag 12 is changed, so that the balanced and reasonable supporting force can be obtained again along with the change of body motion. Specifically, the human physiology inspection apparatus 30 may be disposed at a position of the comfort layer 13 near the waist portion C to inspect vital signs and body movement of the human body 1.
In another embodiment of the present invention, the air pump 21 comprises at least one micro air pump with constant air pressure. In order not to affect sleep, the human body 1 should be prevented from sensing the change of the adjustment process by a slow and weak change as much as possible. Therefore, the excessive air inflation speed and flow rate are not needed, the air inflation speed and flow rate are controlled to be below 80L/min, the pressure is controlled to be below 55KPA, and the noise value is less than 40 decibels, so that the air inflation device is suitable. Specifically, the contact airbag 12, the exhaust solenoid valve 24, and the gas pressure detector 23 may be connected by a gas pipe 25.
In another embodiment of the present invention, the outlet of the air pump 21, the inlet of the exhaust solenoid valve 24 and the interface of the gas pressure detector 23 are connected by a tee 26. The air pump 21 is connected with a port 26a of a tee joint 26, then a second port 26b is connected with an exhaust electromagnetic valve 24, the exhaust electromagnetic valve 24 is a normally closed electromagnetic valve and is used for being opened when exhaust is needed, a third port 26c of the tee joint 26 is connected with an electronic type gas pressure detector 23, the electronic type gas pressure detector 23 is connected with each electromagnetic valve 22 through the gas pressure detector 23, and the air charging and discharging of each contact airbag 12 are achieved through the combination of the on-off states of the exhaust electromagnetic valve 24 and any one of the electromagnetic valves 22. Meanwhile, the internal air pressure inside each contact airbag 12 is determined by an air pressure detector 23 at the outlet of the air pump 21. The inflation pressurization or the exhaust depressurization of the contact airbag 12 is formulated by controlling the open state of the exhaust solenoid valve 24. Thereby changing the pressure of a certain contact air bag 12 area in the mattress or the contact air bag 12 in the whole bed, and realizing the functions of hardness adjustment and the like.
Referring to fig. 3 and 5, in another embodiment of the present invention, the contact airbag 12 includes a strip-shaped airbag body 121, a first conductive portion 122 mounted on an inner upper surface of the airbag body 121, and a second conductive portion 123 mounted on an inner lower surface of the airbag body 121, where the first conductive portion 122 and the second conductive portion 123 are used for sensing that the airbag body 121 is pressed when the first conductive portion 122 abuts against the second conductive portion 123. This structure is easy to mold and can sense whether the airbag body 121 is crushed. Referring to fig. 1 and 5(b), after the air pump 21 inflates the airbag body 121, the airbag body 121 overcomes the external force, the first conductive portion 122 and the second conductive portion 123 are separated, so that the first conductive portion 122 and the second conductive portion 123 are not conducted, and the controller 40 obtains a signal whether the airbag body has been completely turned to be not squashed. Referring to fig. 5(a), when a sufficiently large external force F acts on the surface of the airbag body 121, the upper and lower inner surfaces of the airbag body 121 contact each other, and the sensing is performed by the first conductive part 122 and the second conductive part 123 contacting each other. When the conductive portion is only in the single contact mode, the gas pressure detector 23 can be used to acquire the internal minimum pressure data at the moment when the airbag body 121 is expanded to be turned to be non-squashed through gas filling in the originally squashed state of the airbag body 121. Specifically, referring to fig. 3, the airbag body 121 is provided with an air nozzle 124 for connecting with the air tube 25, so that the assembly is easy, and the inflation and deflation of the airbag body 121 can be realized.
Referring to fig. 4, in another embodiment of the present invention, the first conductive portion 122 is planar, and the second conductive portion 123 includes at least two spaced strip-shaped conductive portions. This configuration is easy to mold, saves material, and ensures reliable conduction between the first conductive part 122 and the second conductive part 123 when the upper and lower inner surfaces of the airbag body 121 are in contact with each other. It is understood that the specific structure of the first conductive portion 122 and the second conductive portion 123 may also be in other forms.
In another embodiment of the present invention, the first conductive portion 122 and the second conductive portion 123 can be made of conductive ink, conductive silver paste, mirror silver ink, graphene material or single-arm carbon nanotube aqueous slurry, and the conductive performance is good. The inner surface of the airbag body 121 is coated with a large-area or multi-point conductive material as needed, or is formed by attaching a metal conductor to the inner wall of the airbag body 121.
Referring to fig. 2 and 3, in another embodiment of the present invention, the length direction of the contact airbag 12 is perpendicular to the direction from the head to the tail of the bed, and the contact airbag 12 is obliquely stacked when not inflated. The scheme is easy to arrange, the contact air bags 12 are obliquely overlapped and pressed, the center distance L between the adjacent contact air bags 12 is closer after the contact air bags 12 are inflated, the pivots of the human body 1 are applied to the human body 1 within the range of the same length, so that the use is more comfortable, and the problem that the comfort degree is influenced by overlarge air bag distance when the air bags are inflated to be round can be avoided. Specifically, the contact airbags 12 have the same and uniformly distributed internal volume, and can provide supporting force for the human body 1 lying on the comfort layer 13 after the contact airbags 12 are inflated. The contact bladder 12 may be square, trapezoidal, circular or other in cross-section.
Referring to fig. 1 and 3, in another embodiment of the present invention, the first conductive portion 122 and the second conductive portion 123 are respectively connected to the controller 40 through wires 125. This structure is easy to assemble, and allows the airbag main body 121 to have a function of sensing whether or not it is crushed in an airtight state. When the airbag body 121 is inflated, the airbag body 121 overcomes the external force, the first conductive part 122 and the second conductive part 123 start to be gradually separated, and the on-off signal of the controller 40 is sent by the lead wires 125 respectively led out from the first conductive part 122 and the second conductive part 123, so that whether the signals are completely converted into the signals which are not squashed can be obtained.
