Description

Technical Field

[0001] The present invention relates to a mattress, and more particularly to a mattress and a mattress drainage control method. Background Art

[0002] A warm and cold mattress uses semiconductors, liquid media, air, etc. to heat or cool the medium through a host, and the medium is connected to the mattress through pipes that wind inside the mattress to exchange heat with the human body, thereby achieving the effect of heating or cooling.

[0003] Currently, due to its good cooling and heating effects, warm and cold mattresses have gradually replaced refrigeration and heating devices such as air conditioners, electric heaters, electric blankets, and fans as the first choice for people. Water is stored in the water tanks of the mattress and the host. If not drained regularly for a long time, the water will become smelly. Therefore, it is necessary to drain the water regularly.

[0004] During the use of a warm and cold mattress, especially during the heating cycle, the water in the warm and cold mattress needs to be heated and circulated repeatedly, which may cause scaling and requires regular replacement of clean water. Moreover, when the cooling or heating function is not required in spring and autumn, the water in the water-based blanket inside the warm and cold mattress also needs to be emptied when storing the warm and cold mattress. In the prior art, it is very troublesome to replace all the water in the host. Traditional drainage methods mostly involve unplugging the external leakage water pipes of the mattress from the water tank inlet and outlet, and the water in the mattress needs to be drained by people raising the mattress little by little. This drainage method is relatively troublesome, time-consuming and laborious, and the water is easy to spill outside and wet the floor.

The third port of the three-way valve is connected to the drain pipe, and it is used to controllably connect the first end of the water delivery pipeline with the main machine inlet pipe or connect the first end of the water delivery pipeline with the drain pipe.

[0010] In some embodiments, the pipe orifice of the main machine outlet pipe is higher than the pipe orifice of the main machine inlet pipe.

For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1. In this embodiment, a mattress is proposed. As Figure 1 shown, it includes a main body 1 and a mattress body 2. The main body 1 includes a housing 11, a water tank 12, a main body water inlet pipe 13, and a main body water outlet pipe 14. Among them, the water tank 12 is arranged inside the housing 11, and the water tank 12 is a closed water tank. The main body water inlet pipe 13 and the main body water outlet pipe 14 are respectively communicated with the water tank 12.

[0025] A water pipeline 3 is arranged inside the mattress body 2. At least the first end 31 of the water pipeline 3 is detachably connected to the main body water inlet pipe 13. The second end 32 of the water pipeline 3 is connected to the main body water outlet pipe 14. When the mattress is in normal refrigeration or heating cycle, the water in the water tank 12 enters the water pipeline 3 from the main body water outlet pipe 14 and the second end 32 of the water pipeline 3, flows through the water pipeline 3, and then circulates back to the water tank 12 from the first end 31 of the water pipeline 3 and the main body water inlet pipe 13.

[0026] The mattress in this embodiment further includes a water inlet valve 4, an air pump 5, and a water pump 6. The water inlet valve 4 is arranged in the main body water inlet pipe 13 and is used to be controlled to open or close to control the on-off of the main body water inlet pipe 13. When the water inlet valve 4 is open, the passage of the main body water inlet pipe 13 is open; when the water inlet valve 4 is closed, the passage of the main body water inlet pipe 13 is disconnected.

[0027] The air pump 5 is arranged inside the housing 11. The exhaust port of the air pump 5 is communicated with the inner cavity of the water tank 12 for containing water. The air pump 5 is used to be controlled to open or close. When the air pump 5 is open, it can inflate the water tank 12. Since the water tank 12 is a closed water tank, the air pressure in the water tank 12 increases.

[0028] The water pump 6 is connected to the main body water outlet pipe 14. The water pump 6 is used to be controlled to open or close. When the water pump 6 is open, it pumps the water in the water tank 12 out from the main body water outlet pipe 14, then enters the water pipeline 3 through the second end 32 of the water pipeline 3, flows through the water pipeline 3, and then circulates back to the water tank 12 from the first end 31 of the water pipeline 3 and the main body water inlet pipe 13. When the water pump 6 is closed, the water cannot form a cycle.

[0029] The main body 1 is also provided with a refrigeration module and / or a heating module for cooling or heating the water in the water tank 12. When the water pump 6 is turned on, the cold / hot water in the water tank 12 is pumped out from the main body water outlet pipe 14, then enters the water delivery pipeline 3 through the second end 32 of the water delivery pipeline 3, exchanges heat with the surrounding environment when flowing through the water delivery pipeline 3, and after achieving refrigeration or heating, it circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main body water inlet pipe 13 to continue absorbing cold or heat. When the user lies on the mattress body 2, since the water delivery pipeline 3 in the mattress body 2 is very close to the human body and has a high heat exchange efficiency, the user can quickly feel cool and comfortable (when refrigerating) or warm (when heating). The water in the water delivery pipeline 3 will simultaneously absorb the heat of the human body and the environment to increase the temperature (when refrigerating) or absorb the cold of the human body and the environment to decrease the temperature (when heating), and then will circulate to the cold end of the refrigeration device 11 again to absorb cold or heat, and so on in a cycle, achieving the technical effect of continuously cooling the mattress.

[0030] When draining the mattress, the main body water inlet pipe 13 is disconnected from the first end 31 of the water delivery pipeline 3, and the water inlet valve 4 is closed to prevent the water in the water tank 12 from flowing out from the port of the main body water inlet pipe 13. Then, the air pump 5 and the water pump 6 are turned on. In this way, the water in the water tank 12 first enters the water delivery pipeline 3 and then is discharged from the first end 31 of the water delivery pipeline. At this time, only the first end 31 of the water delivery pipeline needs to be inserted into or aligned with the water receiving container to catch the discharged water, avoiding the problem of water splashing everywhere.

[0031] In some embodiments, the water inlet valve 4 can be implemented by an electromagnetic valve or a check valve. When using a check valve, it should be unidirectionally conductive from the water delivery pipeline 3 to the main body water inlet pipe 13.

[0032] In this solution, by setting the air pump 5, the air pressure in the water tank 12 can be increased. On the one hand, it can increase the water pressure when the main body water outlet pipe 14 discharges water, which is beneficial to water discharge. On the other hand, when the water level in the water tank 12 is lower than the pipe orifice of the main body water outlet pipe 14, under the action of air pressure, the gas in the water tank 12 will enter the water delivery pipeline 3 from the pipe orifice of the main body water outlet pipe 14, which helps to drain the stored water in the water delivery pipeline 3 completely. The mattress of this embodiment can drain water automatically without manual operation, solving the problems of incomplete drainage and troublesome drainage caused by the traditional method of manually raising the mattress to utilize the gravity of water for drainage.

[0033] In some embodiments, the nozzle of the main machine's water outlet pipe 14 is higher than the nozzle of the main machine's water inlet pipe 13. By setting the nozzle of the main machine's water outlet pipe 14 to be appropriately higher, when draining water, the amount of water drained from the water tank 12 into the water delivery pipeline 3 can be reduced, which helps to quickly lower the water level below the nozzle of the main machine's water outlet pipe 14, and then allows air to enter the water delivery pipeline 3 to quickly empty the stored water in the water delivery pipeline 3. As for the small amount of water remaining in the water tank 12, after the water in the water delivery pipeline 3 is emptied, the small amount of water in the water tank 12 can be poured out.

[0034] In this embodiment, it is preferred that the first end 31 of the water delivery pipeline 3 is detachably connected to the main machine's water inlet pipe 13, and the second end 32 of the water delivery pipeline 3 is detachably connected to the main machine's water outlet pipe 14. When the mattress is not in use, the water delivery pipeline 3 can be unplugged from the corresponding water pipes on the main machine, which is convenient for storage.

[0035] In some embodiments, an air inlet (not shown in the figure due to angle reasons) is provided at the top of the water tank 12, and the exhaust port of the air pump 5 is hermetically connected to the air inlet. By setting the air inlet at the top of the water tank 12, the water in the water tank 12 is prevented from flowing back to the air pump 5.

[0036] Embodiment 2: This embodiment proposes a mattress with another structural form. As shown in the figure, it includes a main machine 1 and a mattress body 2. The main machine 1 includes a housing 11, a water tank 12, a main machine's water inlet pipe 13, and a main machine's water outlet pipe 14. Among them, the water tank 12 is arranged inside the housing 11, and the water tank 12 is a closed water tank. The main machine's water inlet pipe 13 and the main machine's water outlet pipe 14 are respectively communicated with the water tank 12.

[0037] A water delivery pipeline 3 is arranged inside the mattress body 2, and at least the first end 31 of the water delivery pipeline 3 is connected to the main machine's water inlet pipe 13. The second end 32 of the water delivery pipeline 3 is connected to the main machine's water outlet pipe 14. The water in the water tank 12 can enter the water delivery pipeline 3 from the main machine's water outlet pipe 14 and the second end 32 of the water delivery pipeline 3, flow through the water delivery pipeline 3, and then circulate back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main machine's water inlet pipe 13.

[0038] The mattress in this embodiment further includes an air pump 5 and a water pump 6. The air pump 5 is arranged inside the housing 11, and the exhaust port of the air pump 5 is communicated with the inner cavity of the water tank 12 for containing water. The air pump 5 is used to be controlled to be turned on or off. When the air pump 5 is turned on, it can inflate the water tank 12. Since the water tank 12 is a closed water tank, the air pressure in the water tank 12 increases.

[0039] The water pump 6 is connected to the main machine outlet pipe 14. The water pump 6 is used to be controlled to be turned on or off. When the water pump 6 is turned on, the water in the water tank 12 is pumped out from the main machine outlet pipe 14, then enters the water delivery pipeline 3 through the second end 32 of the water delivery pipeline 3, flows through the water delivery pipeline 3 and then circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main machine inlet pipe 13. When the water pump 6 is turned off, the water cannot form a cycle.

[0040] In this embodiment, as Figure 2 , Figure 3 shown, the main machine 1 further includes a three-way valve 7. The three-way valve 7 is arranged at a position on the water delivery pipeline 3 close to the first end 31 of the water delivery pipeline 3, or is arranged on the main machine inlet pipe 13. It can be understood that two ports of the three-way valve 7 are connected in the main pipeline where it is located, and the third port 71 of the three-way valve 7 is connected to the drain pipe 8. The three-way valve 7 is used to be controlled to connect the first end 31 of the water delivery pipeline 3 with the main machine inlet pipe 13, or to connect the first end 31 of the water delivery pipeline 3 with the drain pipe 8.

[0041] When the three-way valve 7 is controlled to connect the first end 31 of the water delivery pipeline 3 with the main machine inlet pipe 13, after the water pump 6 is turned on, the water in the water tank 12 enters the water delivery pipeline 3 from the main machine outlet pipe 14 and the second end 32 of the water delivery pipeline 3, flows through the water delivery pipeline 3 and then circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main machine inlet pipe 13, realizing the normal cooling or heating cycle of the mattress.

[0042] When the three-way valve 7 is controlled to connect the first end 31 of the water delivery pipeline 3 with the drain pipe 8, the first end 31 of the water delivery pipeline 3 is not connected to the main machine inlet pipe 13. After the water pump 6 is turned on, the water in the water tank 12 enters the water delivery pipeline 3 from the main machine outlet pipe 14 and the second end 32 of the water delivery pipeline 3, and then is discharged from the first end 31 of the water delivery pipeline and the drain pipe 8. At this time, only the drain pipe 8 needs to be inserted into or aligned with the water receiving container to catch the discharged water, avoiding the problem of water splashing everywhere.

[0043] In some embodiments, as Figure 3 shown, the drain pipe 8 and the third port 71 of the three-way valve 7 are detachably connected, which is convenient for storage.

[0044] The main body 1 is also provided with a refrigeration module and / or a heating module for refrigerating or heating the water in the water tank 12. When the water pump 6 is turned on, the cold / hot water in the water tank 12 is pumped out from the main body outlet pipe 14, then enters the water delivery pipeline 3 through the second end 32 of the water delivery pipeline 3, exchanges heat with the surrounding environment when flowing through the water delivery pipeline 3, and after achieving refrigeration or heating, it circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main body inlet pipe 13 to continue absorbing cold or heat. When the user lies on the mattress body 2, since the water delivery pipeline 3 in the mattress body 2 is very close to the human body and has a high heat exchange efficiency, the user can quickly feel cool and comfortable (when refrigerating) or warm (when heating). The water in the water delivery pipeline 3 will simultaneously absorb the heat of the human body and the environment and heat up (when refrigerating) or absorb the cold of the human body and the environment and cool down (when heating), and then will circulate to the cold end of the refrigeration device 11 again to absorb cold or heat, and so on in a cycle, achieving the technical effect of continuously cooling the mattress.

[0045] In this solution, by setting the air pump 5, when the air pump 5 is turned on, it can increase the air pressure in the water tank 12. On the one hand, it can increase the water pressure when the water flows out of the main body outlet pipe 14, which is beneficial to the discharge of water. On the other hand, when the water level in the water tank 12 is lower than the pipe orifice of the main body outlet pipe 14, under the action of air pressure, the gas in the water tank 12 will enter the water delivery pipeline 3 from the pipe orifice of the main body outlet pipe 14, which helps to drain the stored water in the water delivery pipeline 3 completely. The mattress of this embodiment can drain water automatically without manual operation, solving the problems of incomplete drainage and troublesome drainage caused by the traditional method of manually raising the mattress to drain water by the gravity of the water itself.

[0046] In some embodiments, the pipe orifice of the main body outlet pipe 14 is higher than the pipe orifice of the main body inlet pipe 13. As Figure 4 shown, by setting the pipe orifice of the main body outlet pipe 14 to be appropriately higher, with a height difference h, when draining water, it can reduce the amount of water drained from the water tank 12 into the water delivery pipeline 3 for drainage, which helps to quickly lower the water level below the pipe orifice of the main body outlet pipe 14, and then air enters the water delivery pipeline 3 to quickly empty the stored water in the water delivery pipeline 3. As for the small amount of water remaining in the water tank 12, after the water in the water delivery pipeline 3 is emptied, just pour out the small amount of water in the water tank 12.

[0047] In this embodiment, it is preferably that the first end 31 of the water delivery pipeline 3 is detachably connected to the main body inlet pipe 13, and the second end 32 of the water delivery pipeline 3 is detachably connected to the main body outlet pipe 14. When the mattress is not in use, the water delivery pipeline 3 is unplugged from the corresponding water pipes on the main body, which is convenient for storage.

[0048] In some embodiments, an air inlet (not shown in the figure due to angle reasons) is provided at the top of the water tank 12, and the exhaust port of the air pump 5 is hermetically connected to the air inlet. By arranging the air inlet at the top of the water tank 12, the water in the water tank 12 is prevented from flowing back to the air pump 5.

[0049] Embodiment 3. In this embodiment, a mattress with another structural form is proposed. As Figure 5 shown, it includes a main unit 1 and a mattress body 2. The main unit 1 includes a housing 11, a water tank 12, a main unit water inlet pipe 13, and a main unit water outlet pipe 14. Among them, the water tank 12 is arranged inside the housing 11, and the water tank 12 is a sealed water tank. The main unit water inlet pipe 13 and the main unit water outlet pipe 14 are respectively communicated with the water tank 12.

[0050] A water delivery pipeline 3 is arranged inside the mattress body 2, and at least the first end 31 of the water delivery pipeline 3 is detachably connected to the main unit water inlet pipe 13. The second end 32 of the water delivery pipeline 3 is connected to the main unit water outlet pipe 14. When the mattress is in normal refrigeration or heating cycle, the water in the water tank 12 enters the water delivery pipeline 3 from the main unit water outlet pipe 14 and the second end 32 of the water delivery pipeline 3, flows through the water delivery pipeline 3, and then circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main unit water inlet pipe 13.

[0051] An air pump 5 is arranged inside the housing 11, and the exhaust port of the air pump 5 is communicated with the inner cavity of the water tank 12 for containing water. The air pump 5 is used to be controlled to be turned on or off. When the air pump 5 is turned on, it can inflate the water tank 12. Since the water tank 12 is a sealed water tank, the air pressure in the water tank 12 increases.

[0052] The mattress of this embodiment further includes a main unit drain pipe 9 and a drain valve 10. The main unit drain pipe 9 is communicated with the water tank 12, and the drain valve 10 is connected to the main unit drain pipe 9. When the mattress is in normal refrigeration or heating cycle, the drain valve 10 is closed.

[0053] A water pump 6 is connected to the main unit water outlet pipe 14. The water pump 6 is used to be controlled to be turned on or off. When the water pump 6 is turned on, the water in the water tank 12 is pumped out from the main unit water outlet pipe 14, then enters the water delivery pipeline 3 through the second end 32 of the water delivery pipeline 3, flows through the water delivery pipeline 3, and then circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main unit water inlet pipe 13. When the water pump 6 is turned off, the water cannot form a cycle.

[0054] The main unit 1 is also provided with a refrigeration module and / or a heating module for cooling or heating the water in the water tank 12. When the water pump 6 is turned on, the cold / hot water in the water tank 12 is pumped out from the main unit water outlet pipe 14, then enters the water pipe line 3 through the second end 32 of the water pipe line 3. When flowing through the water pipe line 3, it exchanges heat with the surrounding environment to achieve refrigeration or heating, and then circulates back to the water tank 12 from the first end 31 of the water pipe line 3 and the main unit water inlet pipe 13 to continue absorbing cold or heat. When the user lies on the mattress body 2, since the water pipe line 3 in the mattress body 2 is very close to the human body and the heat exchange efficiency is high, the user will quickly feel cool and comfortable (when refrigerating) or warm (when heating). The water in the water pipe line 3 will simultaneously absorb the heat of the human body and the environment to increase the temperature (when refrigerating) or absorb the cold of the human body and the environment to decrease the temperature (when heating), and then will circulate to the cold end of the refrigeration device 11 again to absorb cold or heat, and so on in a cycle, achieving the technical effect of continuously cooling the mattress.

[0055] When the mattress drains water, the drain valve 10 is opened, the water tank 12 is communicated with the main unit drain pipe 9, and the water in the water tank 12 is discharged through the main unit drain pipe 9. At this time, only the first end 31 of the water pipe line 3 needs to be inserted into or aligned with the water receiving container to catch the discharged water, avoiding the problem of water splashing everywhere.

[0056] When the mattress drains water, it also includes turning on the air pump 5 and the water pump 6. A part of the water in the water tank 12 enters the water pipe line 3 through the main unit water outlet pipe 14 and the second end 32 of the water pipe line 3, and then circulates from the first end 31 of the water pipe line and the main unit water inlet pipe 13 to the water tank 12. When the water level in the water tank 12 is lower than the pipe orifice of the main unit water outlet pipe 14, the air pump 5 can increase the air pressure in the water tank 12. Under the action of the air pressure, the gas in the water tank 12 will enter the water pipe line 3 from the pipe orifice of the main unit water outlet pipe 14, which helps the stored water in the water pipe line 3 to be completely circulated back to the water tank 12 for complete discharge.

[0057] The mattress of this embodiment can drain water automatically without manual operation, solving the problems of incomplete drainage and troublesome drainage caused by the traditional method of manually raising the mattress to drain water by the gravity of the water itself.

[0058] In some embodiments, the pipe orifice of the main unit water outlet pipe 14 is higher than the pipe orifice of the main unit water inlet pipe 13. By setting the pipe orifice of the main unit water outlet pipe 14 appropriately higher, the drainage volume of the water entering the water pipe line 3 from the water tank 12 can be reduced when draining water, which helps the water level to quickly drop below the pipe orifice of the main unit water outlet pipe 14, and then air enters the water pipe line 3 to quickly empty the stored water in the water pipe line 3. As for the water in the water tank 12, it can be completely discharged through the main unit drain pipe 9 after the water in the water pipe line 3 is emptied.

[0059] In some embodiments, the nozzle of the main machine water inlet pipe 13 is higher than the nozzle of the main machine drain pipe 9, that is, the nozzle of the main machine drain pipe 9 is the lowest, which is conducive to discharging the water in the water tank 12 completely.

[0060] In some embodiments, an air inlet (not shown in the figure due to angle reasons) is provided at the top of the water tank 12, and the exhaust port of the air pump 5 is hermetically connected to the air inlet. By arranging the air inlet at the top of the water tank 12, the water in the water tank 12 is prevented from flowing back to the air pump 5.

[0061] In some embodiments, the first end 31 of the water delivery pipeline 3 is detachably connected to the main machine water inlet pipe 13, and the second end 32 of the water delivery pipeline 3 is detachably connected to the main machine water outlet pipe 14. When the mattress is not in use, the water delivery pipeline 3 is unplugged from the corresponding water pipes on the main machine, which is convenient for storage.

[0062] Embodiment 4, this embodiment proposes a mattress drainage control method, as Figure 5 shown, the mattress involved in the mattress drainage control method includes: a main machine 1 and a mattress body 2, and the main machine 1 includes a housing 11, a water tank 12, a main machine water inlet pipe 13 and a main machine water outlet pipe 14. Among them, the water tank 12 is arranged in the housing 11, and the water tank 12 is a closed water tank. The main machine water inlet pipe 13 and the main machine water outlet pipe 14 are respectively communicated with the water tank 12.

[0063] A water delivery pipeline 3 is arranged in the mattress body 2, and at least the first end 31 of the water delivery pipeline 3 is detachably connected to the main machine water inlet pipe 13. The second end 32 of the water delivery pipeline 3 is connected to the main machine water outlet pipe 14. When the mattress is in normal refrigeration or heating cycle, the water in the water tank 12 enters the water delivery pipeline 3 from the main machine water outlet pipe 14 and the second end 32 of the water delivery pipeline 3, flows through the water delivery pipeline 3 and then circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main machine water inlet pipe 13.

[0064] An air pump 5 is arranged in the housing 11, and the exhaust port of the air pump 5 is communicated with the inner cavity of the water tank 12 for containing water. The air pump 5 is used to be controlled to be turned on or off. When the air pump 5 is turned on, it can inflate the water tank 12. Since the water tank 12 is a closed water tank, the air pressure in the water tank 12 increases.

[0065] The mattress of this embodiment further includes a main machine drain pipe 9 and a drain valve 10. The main machine drain pipe 9 is communicated with the water tank 12, and the drain valve 10 is connected to the main machine drain pipe 9. When the mattress is in normal refrigeration or heating cycle, the drain valve 10 is closed.

[0066] The water pump 6 is connected to the main machine outlet pipe 14. The water pump 6 is used to be controlled to open or close. When the water pump 6 is opened, the water in the water tank 12 is pumped out from the main machine outlet pipe 14, then enters the water delivery pipeline 3 through the second end 32 of the water delivery pipeline 3, and after flowing through the water delivery pipeline 3, it circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main machine inlet pipe 13. When the water pump 6 is closed, the water cannot form a cycle.

[0067] The mattress drainage control method includes: Receiving a drainage control command; Controlling the drainage valve 10 to open, controlling the water pump 6 and the air pump 5 to open. When the water level is not lower than the pipe orifice of the main machine outlet pipe 14, a part of the water in the water tank 12 enters the water delivery pipeline through the main machine outlet pipe 14 and circulates back to the water tank 12 through the main machine inlet pipe 13.

[0068] When the water level is lower than the pipe orifice of the main machine outlet pipe 14, the gas in the water tank 12 enters the water delivery pipeline through the main machine outlet pipe 14, squeezing the residual water in the water delivery pipeline 3 to circulate back to the water tank 12 through the main machine inlet pipe 13, and the water in the water tank 12 is discharged through the main machine drain pipe 9.

[0069] The main machine 1 is also provided with a refrigeration module and / or a heating module for refrigerating or heating the water in the water tank 12. When the water pump 6 is opened, the cold / hot water in the water tank 12 is pumped out from the main machine outlet pipe 14, then enters the water delivery pipeline 3 through the second end 32 of the water delivery pipeline 3, exchanges heat with the surrounding environment when flowing through the water delivery pipeline 3, realizes refrigeration or heating, and then circulates back to the water tank 12 from the first end 31 of the water delivery pipeline 3 and the main machine inlet pipe 13 to continue absorbing cold or heat. When the user lies on the mattress body 2, since the water delivery pipeline 3 in the mattress body 2 is very close to the human body and the heat exchange efficiency is high, the user can quickly feel cool and comfortable (when refrigerating) or warm (when heating). The water in the water delivery pipeline 3 will simultaneously absorb the heat of the human body and the environment to warm up (when refrigerating) or absorb the cold of the human body and the environment to cool down (when heating), and then will circulate back to the cold end of the refrigeration device 11 to absorb cold or heat again, and so on in a cycle, achieving the technical effect of continuously cooling the mattress.

[0070] When the mattress is draining water, the drainage valve 10 is opened, the water tank 12 is communicated with the main machine drain pipe 9, and the water in the water tank 12 is discharged through the main machine drain pipe 9. At this time, only the first end 31 of the water delivery pipeline 3 needs to be inserted into or aligned with the water receiving container to catch the discharged water, avoiding the problem of water splashing everywhere.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, for those of ordinary skill in the art, it is still possible to modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions required to be protected by the present invention.
