In this embodiment, the number of the water pipes 2 is 2, the water pipes are a first water pipe 22 and a second water pipe 23, the first water pipe 22 and the second water pipe 23 are horizontally embedded in the mattress body 1 in parallel, and the second water pipe 23 is used as a spare water pipe; of course, the amount of water in the spare water pipe may be 2, 3 or more.

A water pump, a heating device and a refrigerating device are arranged in the external water tank 5, the water pump is used for driving water flow circulation in the water pipe 2 and the external water tank 5, and the heating device is an electric heating wire; the refrigerating device is a refrigerating sheet; the electric heating wire is made of metal, can normally work in a water environment and can quickly raise the temperature of water; the refrigerating piece is a semiconductor refrigerating piece and is a heat transfer tool, the semiconductor refrigerating piece comprises two ceramic pieces, N-type and P-type semiconductor materials (bismuth telluride) are arranged between the two ceramic pieces, when a thermocouple pair formed by connecting one N-type semiconductor material and one P-type semiconductor material has current flowing through, heat transfer can be generated between the two ends, the heat can be transferred from one end to the other end, and thus temperature difference is generated to form a cold end and a hot end; the cold end can be used as a refrigerating device in the external water tank 5.

The external main control computer is a processing module and a temperature setting module, and specifically, the processing module can be a single chip microcomputer;

the flow monitoring device 3 is a flow sensor, the flow detecting device 3 includes a first flow sensor 31 and a second flow sensor 32, and the first flow sensor 31 is disposed at the water inlets of the first water pipe 22 and the second water pipe 23; the second flow sensor 32 is disposed at the outlet of the first water pipe 22 and the second water pipe 23.

The electromagnetic valve 4 comprises a first electromagnetic valve 41 and a second electromagnetic valve 42, and the first electromagnetic valve 41 is arranged at the water inlet and the water outlet of the first water pipe 22 and the second water pipe 23; the second electromagnetic valve 42 is disposed at the water outlet of the first water pipe 22 and the water outlet of the second water pipe 23.

The first flow sensor 31 and the second flow sensor 32 are used for monitoring the flow rate of the inlet and the outlet of the first water pipe 22 per unit time and transmitting flow rate signals to the external master controller, and the external master controller analyzes the flow rate signals;

the first electromagnetic valve 41 at the inlet of the first water pipe 22 and the second electromagnetic valve 42 at the outlet are in an open state, and if the flow rate of the inlet detected by the first flow sensor 31 in unit time is equal to or within an allowable deviation range (the allowable deviation range refers to the upper and lower 20ml/min of the flow rate of the inlet or the outlet), the external master controller determines that the first water pipe 22 is normal, that is, no water leakage or blockage occurs;

if the flow rate per unit time of the inlet detected by the first flow sensor 31 and the flow rate per unit time of the outlet detected by the second flow sensor 32 are outside the allowable deviation range (the allowable deviation range refers to the upper and lower 20ml/min of the flow rate of the inlet or the outlet), the inlet flow rate is greater than the outlet flow rate, the external master controller determines that the first water pipe 22 leaks water or is blocked halfway, and in order to ensure that the mattress can continue to be used normally, the external master controller controls the first electromagnetic valve 41 at the inlet and the second electromagnetic valve 42 at the outlet of the first water pipe 22 to be closed, controls the first electromagnetic valve 41 at the inlet and the second electromagnetic valve 42 at the outlet of the second water pipe 23 to be opened, the water in the water tank flows from the main water pipe 21 through the second water pipe 23 so that the mattress continues to operate normally.

The waterproof sealing bag 24 is vacuum-wrapped on the surface of each water pipe 2. The waterproof sealing bag 24 is tightly attached to the surface of the water pipe 2, and when the water pipe 2 is broken, water continues to be in the waterproof sealing bag 24 and cannot permeate into the filler in the mattress.

A water pump is arranged in the external water tank 5 and is connected with the main water pipe 21. The water pump realizes water circulation.

The water pipe 2 is embedded in the mattress body 1 in an S shape.

The surface of the mattress body 1 is provided with a plurality of pressure sensors 6, and each pressure sensor 6 is connected to the external master controller.

In this embodiment, the number of the pressure sensors 6 is 8, and the pressure sensors are uniformly distributed on the surface of the mattress, however, more pressure sensors 6 may be provided to more accurately sense the pressure.

The mattress body 1 surface is provided with temperature sensor 7, temperature sensor 7's quantity is 3, evenly distributed in mattress body 1's centre. The mattress user may also set a desired temperature value in the temperature setting module.

The temperature sensor 7 is used for monitoring the temperature of the surface of the mattress; the external master controller obtains the temperature sensor 7, when the surface of the mattress reaches the temperature set by the user, the water in the water tank stops heating, and when the temperature of the surface of the mattress exceeds or is lower than the temperature set by the user, the water in the water tank is refrigerated or heated to the temperature value set by the user.

The pressure sensor 6 is used for sensing the pressure change of a human body to the mattress, and the pressure sensor 6 obtains a pressure value and a pressure change value and transmits the pressure value and the pressure change value to the external main controller; furthermore, the external main controller judges the change range and the change frequency of the pressure value within a certain time (such as 30 minutes) in the past by the user based on the pressure value and the pressure change value; when the variation range is larger than the predetermined variation range threshold value and the variation frequency is larger than the predetermined variation frequency threshold value, the user is considered to be in a non-sleep state (namely, a sleep stage of lying on the bed); when the variation range is larger than the variation range threshold value, but the variation frequency is lower than the variation frequency threshold value, the current user is considered to be in a light sleep state (namely, all light sleep states in the whole sleep process); when the variation range is smaller than the variation range and the variation frequency is lower than the variation frequency threshold, the current user is considered to be in the deep sleep state (i.e. all the deep sleep states in the whole sleep process). The turning over action frequency of the human body on the mattress body 1 is more and the action amplitude is larger when the human body is in the stage of falling asleep; when the patient is in the shallow sleep stage, the number of turning-over actions of the human body is less than that of the preparation for the sleep stage; during the deep sleep stage, the turn-over action times and action amplitude of the human body are obviously reduced relative to the former two stages; furthermore, the frequency and amplitude of the turning actions of the human body can cause the vibration of the mattress body 1 and simultaneously cause the change of the range and frequency of the pressure value of the mattress body 1 caused by the human body. Therefore, different sleep stages of the human body can be judged according to the change range and the change frequency of the pressure value of the human body to the mattress body 1; when the user gets into the deep sleep stage, for guaranteeing the sleep quality, outside master controller will the temperature of the water of outside water tank 5 descends 2-3 degrees centigrade, and the temperature of mattress body 1 is to descending 2-3 degrees centigrade promptly.

The present invention is not limited to the above-described embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present invention.
