DETAILED DESCRIPTION

[0020] The technical solutions will be described clearly and completely below in combination with the drawings in the embodiments of the present application.

[0021] First embodiment: Figures 1-3 As shown, a self-adjusting bed based on temperature sensing includes, from top to bottom, an elastic layer 11, an air cushion layer 12, an upper bearing layer 13, and a lower bearing layer 14, and the four are collectively wrapped with an outer protective layer 101. A rectangular cushion ring 102 is fixedly connected between the edges of the air cushion layer 12 and the upper bearing layer 13. Two air bag cushions 2 are fixedly embedded on the air cushion layer 12, and the two air bag cushions 2 are distributed in a staggered manner. Self-adjusting units are provided outside the two air bag cushions 2.

[0022] As Figures 4-5The air bag cushion 2 comprises a plurality of air cushion pieces 21 arranged in a rectangular array, a plurality of transverse connecting strips 22 respectively fixedly connected between the transverse ends of two adjacent air cushion pieces 21, a plurality of longitudinal connecting strips 23 respectively fixedly connected between the longitudinal ends of two adjacent air cushion pieces 21, and a plurality of selection columns 24 respectively connected at the centers of the lower ends of the air cushion pieces 21. The plurality of selection columns 24 are all fixedly connected with the upper ends of the upper bearing layer 13. The air cushion piece 21 comprises a pre-pressing bladder piece 211 located outside the air cushion layer 12 and an inner fixed bladder piece 212 located inside the air cushion layer 12. The pre-pressing bladder piece 211 is of an elastic sealing structure, so that the pre-pressing bladder piece 211 can deform and change in hardness with the gravity of the human body and the filling of air. The inner fixed bladder piece 212 is of a hard structure. The upper ends of the two air bag cushions 2 are all fixedly penetrated through the upper surface of the air cushion layer 12 and extend above the air cushion layer 12, i.e., the pre-pressing bladder piece 211 is located above the air cushion layer 12. When a human body lies on the bed cushion, under the action of the gravity of the human body, the pre-pressing bladder piece 211 can deform downward, so as to facilitate the opening of the corresponding selection column 24, so that when air is filled or discharged, the air can enter the air cushion piece 21 corresponding to the human body, so as to realize targeted extrusion and effectively promote the blood circulation of the human body. At the same time, the user is not easy to have pressure sores due to long-term continuous stress in a local part. The plurality of air cushion pieces 21 on the two air bag cushions 2 are distributed in a staggered manner. The two temperature adjusting cavities are distributed in a staggered manner in the up-down direction, and the two temperature adjusting cavities are respectively arranged corresponding to the two air bag cushions 2. The end portions of the air inlet pipes 401 of the two temperature adjusting cavities are located on the same side of the upper bearing layer 13, so as to adapt to the two air bag cushions 2 distributed in a staggered manner in the up-down direction, so that the air filling and discharging operations in the two air bag cushions 2 can be independent of each other, and the alternating air filling and discharging functions can be realized.

[0023] As Figure 6 The self-adjusting unit comprises a temperature adjusting cavity arranged in the upper bearing layer 13. The temperature adjusting cavity comprises a plurality of strip-shaped cavities 41 dug in the upper bearing layer 13 and a plurality of connecting pipes 42 fixedly connected between two adjacent strip-shaped cavities 41. Two adjacent connecting pipes 42 are respectively located on the two sides of one strip-shaped cavity 41. One strip-shaped cavity 41 at the outermost side is fixedly connected with an air inlet pipe 401 at the end portion. The end portion of the air inlet pipe 401 is fixedly penetrated through the upper bearing layer 13, the lower bearing layer 14 and the outer protective layer 101 and extends below the outer protective layer 101. In use, the air inlet pipe 401 extending below the outer protective layer 101 can be connected with an air pump outside, so as to realize air filling and discharging in the air bag cushion 2. Specifically, an electromagnetic valve is connected on each of the two air inlet pipes 401. A three-way valve is connected on the air outlet of the air pump. Two idle ports of the three-way valve are respectively connected with the two air inlet pipes 401. The electromagnetic valve can be used to connect the two temperature adjusting cavities with the air pump at different times, so that the extrusion on the human body can be presented in an alternating manner.

[0024] It is worth noting that only when the mattress is not in use, both solenoid valves will be closed at the same time, and when in use, both will not be closed at the same time. When working, the states of the two are opposite. After inflating one temperature regulating cavity, the corresponding solenoid valve is not closed first, and after an interval of at least 3-5 seconds, the state of the two solenoid valves is switched when preparing to inflate the other temperature regulating cavity, so that the air filled in the temperature regulating cavity can automatically diffuse in the interval time, and the inflation state of the corresponding air cushion piece 21 is released, preparing for the next inflation.

[0025] As Figures 7-8 , the selection column 24 includes an outer base pipe 241 fixedly connected with the lower end of the inner fixed capsule 212, a guide rod 242 fixedly connected with the inner top of the pre-pressing capsule 211, and a reverse plug ball 243 fixedly connected with the lower end of the guide rod 242. The inside of the outer base pipe 241 is drilled with a variable diameter hole, the inner diameter of the lower part of the variable diameter hole is larger than that of the upper part, the diameter of the reverse plug ball 243 is between the inner diameters of the upper and lower parts of the variable diameter hole, and the guide rod 242 is movably penetrated through the small diameter section of the outer base pipe 241 and extends into the large diameter section. When not subjected to external pressure, the reverse plug ball 243 is in contact with the variable diameter part of the outer base pipe 241. Figure 7 When not subjected to the extrusion force of the human body, when the air passes through the selection column 24, it will generate a pushing force on the reverse plug ball 243 from bottom to top, so that the reverse plug ball 243 is in contact with the variable diameter part of the variable diameter hole, so that the air cannot enter the corresponding air cushion piece 21. Figure 9 Only when subjected to the extrusion force of the human body, due to the deformation of the pre-pressing capsule 211, the reverse plug ball 243 moves away from the variable diameter part and moves upward, so that the air flow can hardly push the reverse plug ball 243, so that the gas can smoothly enter the corresponding air cushion piece 21, realizing the targeted extrusion and temperature regulation of the human body. The lower end of the outer base pipe 241 is provided with an opening, so that the air in the temperature regulating cavity can enter the air cushion piece 21 along the outer base pipe 241. The end parts of the plurality of outer base pipes 241 in the same column are fixedly penetrated through the upper bearing layer 13 and communicated with the corresponding strip-shaped cavities 41. The outside air is first introduced into the strip-shaped cavities 41 through the air pump, and then under the action of the selection column 24, it is introduced into the air cushion piece 21 corresponding to the human body, realizing the targeted and alternating extrusion of the human body, so as to promote blood circulation and reduce the occurrence of pressure sores.

[0026] A self-adjusting mattress based on temperature sensing, the method for using the same comprises the following steps: S1, when the mattress is installed on the bed frame, an air pump with an automatic temperature control unit is arranged at the bottom of the bed frame, and the air inlet pipe 401 is connected with the air pump. The automatic temperature control unit is a prior art and will not be described in detail here. In spring and autumn when the temperature is suitable, the automatic temperature control unit can be closed, so that the air enters the temperature regulating cavity at room temperature. S2, when the user lies on the mattress, due to the pressure of the human body on the mattress, the corresponding air cushion piece 21 is deformed downward under stress, and the selection column 24 is conducted. S31, in winter, the automatic temperature control unit heats the air entering the air pump, and then the air pump delivers the hot air to the temperature adjusting cavity along the air inlet pipe 401, and then the hot air moves to the air cushion piece 21 along the temperature adjusting cavity and the opened selection column 24, on the one hand, the air cushion piece 21 is hardened, so that the extrusion effect can be generated at the contact part between the human body and the mattress, on the other hand, only the part where the human body lies is heated, and the comfort of the user in winter is improved, and then the air in the corresponding temperature adjusting cavity is controlled to flow back, and the hot air is filled into another temperature adjusting cavity, so that the air cushion piece 21 on another air bag cushion 2 is hardened, and the alternating extrusion of the human body is realized, which effectively helps the blood circulation of the human body and reduces the occurrence of numbness or pressure sores caused by long-term same posture; S32, in summer, the automatic temperature control unit cools the air entering the air pump, and then the process of step S31 is repeated, so that the area where the user lies can be cooled, and the part where the user contacts the mattress is not easy to sweat, and the comfort of the user is improved.

[0027] Through the setting of the self-adjusting unit, on the one hand, the temperature of the air entering the mattress can be automatically adjusted according to the environmental temperature, so that the temperature of the contact part between the mattress and the human body is increased in winter, and the temperature of the contact part between the mattress and the human body is reduced in summer, so that the self-adaptive adjustment of the temperature is realized, on the other hand, the contact part between the human body and the mattress can be alternately extruded, so that the blood circulation is effectively promoted, and the part of the human body is not easy to appear numbness or pressure sores caused by long-term immobility, compared with the existing technology, the energy consumption of the long-term bedridden user using the mattress can be effectively reduced while ensuring the comfort.

[0028] The second embodiment is as follows: The second embodiment is as follows:

[0029] Figure 10 It is shown that the self-adjusting unit includes an air inlet pipe 201 fixedly connected with the air cushion piece 21 in the middle of the most edge column, a plurality of horizontal pipes 202 fixedly connected between the horizontal ends of the selection column 24, and a plurality of vertical pipes 203 fixedly connected between the vertical ends of the selection column 24, the end of the air inlet pipe 201 is fixedly connected through the upper bearing layer 13, the lower bearing layer 14 and the outer protective layer 101 and extends to the lower side of the outer protective layer 101, and the air inlet pipe 201 is communicated with the corresponding air cushion piece 21, such as Figure 11 The connection points of the horizontal pipe 202 and the vertical pipe 203 with the selection column 24 are located on the large diameter section of the variable diameter hole, and the lower end of the outer base pipe 241 is a sealed structure, such as Figures 11-12In the embodiment, the air inlet pipe 201 is connected to an air pump. In use, under the action of the air pump, air first enters the first air cushion piece 21, and then diffuses between the longitudinal guide pipe 203 and the transverse guide pipe 202 in the whole through area through the corresponding selection through column 24. The selection through column 24 in the selection communication area of the mattress subjected to the pressure of the human body is conducted, so that air can flow reversely into the corresponding air cushion piece 21, realizes the targeted resistance to the user, and promotes blood circulation in a targeted manner, such as Figure 13 The air chamber cushion 2 is divided into a through area located in the middle and two selection communication areas located on both sides of the through area. The distribution range of the through area is not less than 1 / 4 of the whole area of the air chamber cushion 2. Whether it is a single bed mattress or a double bed mattress, the use probability of the middle part of the mattress is relatively large. Therefore, the area can be completely communicated, so that air can always enter the through area in the middle of the mattress, and the effect of keeping the user warm in winter or taking away heat in summer is better.

[0030] The selection through column 24 corresponding to the through area is not provided with a guide rod 242 and a reverse blocking ball 243, so that the plurality of air cushion pieces 21 on this side can directly enter air. The selection through column 24 corresponding to the selection communication area is provided with a guide rod 242 and a reverse blocking ball 243. The use rate of this part of the area is relatively low. According to the actual stress condition, selective communication can be realized to improve the adaptability of the whole.

[0031] It is worth noting that the through area is only a selectable setting based on the commonly used area. In specific implementation, the through area can also not be provided.

[0032] Compared with the first embodiment, the setting of the temperature adjusting cavity is cancelled, so that the air consumption is lower, and the energy consumption of the air pump is lower. In specific implementation, a suitable embodiment can be selected according to actual needs.

[0033] The above is only a preferred specific embodiment of the present application; includes all the protection scope of the present application. Any person skilled in the art can make equivalent replacement or change according to the technical solution and the improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
