[0001] The utility model relates to the technical field of sponge mattresses, in particular to a heating sponge mattress. Background Art

[0002] Mattresses, as an item between the human body and the bed board, are favored by people because they can improve the comfort and quality of sleep. Mattresses can be divided into spring mattresses, palm mattresses, latex mattresses and sponge mattresses according to different materials and processes. Mattresses made of different materials can bring different sleeping effects. Among them, sponge mattresses have been widely recognized by consumers due to their high softness and low noise. In order to further improve the comfort of mattresses when using them and meet people's heating needs when sleeping in cold weather, heated mattresses have appeared.

[0003] For example, the patent document with the announcement number CN1994192B discloses an automatic temperature-controlled electric water heating mattress, which includes a mattress, a water heating system and a temperature control system; the water heating system includes a water pipe, a water adding bucket, a water jacket, and a heating pipe; the water pipe is fixed in the mattress, and the water inlet and outlet of the water pipe are respectively connected to the upper and lower parts of the water jacket, the water adding bucket is located above the water jacket and connected to the water jacket through a thin tube, and the heating pipe is located at the bottom of the water jacket; the temperature control system includes a power indication circuit, a heating circuit, and a power limiting circuit; the power indication circuit includes an indicator light, and the heating circuit includes a normally closed switch and a heating resistor; the power limiting circuit includes a diode, a voltage dividing resistor, and a light-emitting diode connected in parallel with the voltage dividing resistor, and a heating resistor in sequence; the heating resistor is placed in the heating pipe. This technical solution uses circulating hot water to heat the mattress, and uses a temperature control system to automatically control the water temperature, so that the bed surface temperature is stable and the heating effect is good.

[0004] Although the above technical solution can realize the heating of the mattress and control the temperature, when a person lies on the mattress, usually only a small area of ​​the mattress is used. During use, the above technical solution heats the entire mattress by laying water pipes in the mattress, and cannot adjust the heating area according to the use of the mattress. As a result, the water pipes need to heat the unused areas during use, resulting in heat energy waste during use and increased heating power of the mattress. Utility Model Content

[0005] The utility model aims to provide a heating sponge mattress to solve the technical problem in the prior art that the heating area cannot be adjusted according to the use of the mattress, resulting in waste of heat energy during use and increased heating power of the mattress.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a heating sponge mattress, comprising a sponge layer and a heating pipe network, wherein the heating pipe network is laid on the sponge layer, and a heat-carrying medium flows through the heating pipe network; the heating pipe network comprises a plurality of heating transverse pipes and a plurality of heating longitudinal pipes, wherein the heating transverse pipes and the heating longitudinal pipes are staggered with each other, and the intersections of the heating transverse pipes and the heating longitudinal pipes are interconnected; an input port and an output port are provided on the heating pipe network, wherein the input port and the output port are located on opposite sides of the sponge layer, and the output port is located in the middle of one side of the sponge layer, and the input port and the output port are both connected to a heating device.

[0007] The principle and advantage of this solution are: when the mattress needs to be heated, the heat carrier medium is heated by the heating device, the heated heat carrier medium is transported to the heating pipe network, the heat carrier medium is filled in the heating pipe network, the heat carrier medium emits heat on the surface of the mattress to heat the surface of the mattress, and then it is transported back to the heating device for reheating. When the heat carrier medium is filled in the heating pipe network, the sponge layer is squeezed by the human body and some areas are sunken. Under the action of gravity, the heat carrier medium preferentially flows to the sunken area of ​​the sponge layer, focusing on heating the use area of ​​the mattress.

[0008] In this solution, the heating pipe network laid on the sponge layer is connected in a staggered manner, so that the heat-carrying medium in the heating pipe network can flow freely in the horizontal and vertical directions on the surface of the sponge mattress, so that when a depression appears on the surface of the sponge layer, the heating pipe network in the depressed area can be fully filled with the heat-carrying medium for heating, thereby improving the targeted heating of the mattress surface. In addition, by arranging the output pipe in the middle of one side of the sponge layer, after the heat-carrying medium fills the heating pipe network in the depressed area of ​​the sponge layer, the output port can timely output the heat-carrying medium in the heating pipe network under the overflow effect, so that the heating pipe network area above the output port is not filled with the heat-carrying medium, so that the flow of the heat-carrying medium can be adjusted according to the actual position of the mattress, ensuring that the filling of the heat-carrying medium matches the actual situation, and realizing that the mattress is mainly heated in the use area when heating, reducing the waste of heat energy.

[0009] Preferably, as an improvement, the extension direction of the heating transverse pipe is parallel to the width direction of the sponge layer, and a plurality of heating transverse pipes are spaced apart on the upper surface of the sponge layer; the extension direction of the heating longitudinal pipe is parallel to the length direction of the sponge layer, and a plurality of heating longitudinal pipes are spaced apart on the sponge layer. This allows the heating pipe network to be evenly arranged on the surface of the sponge layer, improves the coverage of the heating pipe network on the sponge layer, ensures the heating effect, and improves the freedom of the heat medium to flow in the heating pipe network.

[0010] Preferably, as an improvement, the heating device comprises a heating tank, the output port is connected to the heating tank, and the heating tank is used to heat the heat-carrying medium output from the output port.

[0011] Preferably, as an improvement, the heating device is further provided with a liquid storage cavity, the liquid storage cavity is used to store the heat medium heated by the heating tank; the input port is connected to the liquid storage cavity. By providing the liquid storage cavity in the heating device, the heating device can adjust the amount of heat medium delivered to the heating pipe network according to the actual demand of the heating pipe network for the heat medium.

[0012] Preferably, as an improvement, a delivery pump is provided in the liquid storage chamber, and the delivery pump is used to deliver the heat-carrying medium in the liquid storage chamber to the heating network.

[0013] Preferably, as an improvement, a fixing groove is provided on the upper surface of the sponge layer, and the heating pipe network is embedded in the fixing groove, so that the heating pipe network cannot be felt during use, which improves the comfort of the mattress and reduces the pressure on the heating pipe network during use, thereby ensuring the smooth flow of the heat medium in the heating pipe network.

[0014] Preferably, as an improvement, the heating transverse pipe and the heating longitudinal pipe are both hoses, so that the heating pipe network can be recessed along with the sponge layer during use, facilitating the flow of the heat medium.

[0015] Preferably, as an improvement, the inner walls of the heating transverse tube and the heating longitudinal tube are both provided with a plurality of supporting protrusions, and the plurality of supporting protrusions are staggeredly distributed along the circumferential direction of the inner walls of the heating transverse tube or the heating longitudinal tube. When the heating pipe network is deformed by extrusion, the pipe wall of the heating pipe network can still have gaps for the heat carrier medium to flow in the heating pipe network under the action of the supporting protrusions, thereby ensuring that the heat carrier medium can flow smoothly in the heating pipe network, avoiding blockage of the heating pipe network, and improving the safety of the heating pipe network.

[0018] The following is further described in detail through specific implementation methods:

[0019] The reference numerals in the drawings of the specification include: sponge layer 1, fixing groove 101, heating pipe network 2, heating horizontal pipe 201, heating vertical pipe 202, output pipe 203, supporting protrusion 204, heating device 3, placement groove 301, and fabric layer 4.

[0020] As attached Figure 1 As shown, there is a heating sponge mattress, including a sponge layer 1 and a heating pipe network 2. The heating pipe network 2 is laid on the sponge layer 1. A heat carrier medium flows in the heating pipe network 2. The heating pipe network 2 is used to heat the surface of the sponge mattress through the heat carrier medium.

[0021] The heating pipe network 2 includes a plurality of heating transverse pipes 201 and a plurality of heating longitudinal pipes 202. The extension direction of the heating transverse pipes 201 is parallel to the width direction A of the sponge layer 1, and the plurality of heating transverse pipes 201 are spaced apart on the upper surface of the sponge layer 1; the extension direction of the heating longitudinal pipes 202 is parallel to the length direction B of the sponge layer 1, and the plurality of heating longitudinal pipes 202 are spaced apart on the sponge layer 1. The intersections of the heating transverse pipes 201 and the heating longitudinal pipes 202 are interconnected, so that the heating pipe network 2 forms a crisscross and interpenetrating transmission network on the sponge layer 1. The heating pipe network 2 can be evenly arranged on the surface of the sponge layer 1, thereby increasing the coverage of the heating pipe network 2 on the sponge layer 1 to ensure the heating effect, and increasing the degree of freedom of the heat medium flowing in the heating pipe network 2.

[0022] An input port and an output port are provided on the heating pipe network 2, wherein the input port and the output port are respectively located at the two ends of the sponge layer 1 along the extension direction of the length direction B, wherein the input port is located on the center line of one side of the sponge layer 1, and specifically the input port and the output port are respectively located on one side of the width direction A of the sponge layer 1, wherein the output port is located in the middle of one side of the width direction A of the sponge layer 1; the input port is used to transport the heat carrier medium into the heating pipe network 2, and the output port is used to output the heat carrier medium in the heating pipe network 2; wherein the heat carrier medium can be water, mineral oil or organic matter and other materials, and preferably in this embodiment, water is used as the heat carrier medium to heat the sponge mattress. The input port and the output port are set at the two ends of the sponge mattress in the length direction B, so that the heat carrier medium can flow on the mattress along the direction of the human body lying, ensuring that the human body lying area can be fully filled with the heat carrier medium, and ensuring the heating effect of the mattress. In addition, the output port is arranged in the middle of the width direction A of the sponge layer 1, so that the output port can be at a shorter distance from the left side, the right side and the middle part of the mattress. When the left side, the right side or the middle part of the mattress is sunken when lying down, the heat carrier medium can be immediately discharged through the output port after filling the heating pipe network 2 in the sunken area, thereby avoiding that the heat carrier medium is filled in all areas of the heating pipe network 2, resulting in a reduction in the heating effect of the heat carrier medium on the mattress, while improving the utilization rate of the heat energy in the heat carrier medium.

[0023] The input port of the heating network 2 is connected to the input pipe, and the output port is connected to the output pipe 203. Both the input pipe and the output pipe 203 are connected to the heating device 3. The heating device 3 is used to heat the heat-carrying medium flowing in the heating network 2. The heating device 3 includes a heating tank. The end of the output pipe 203 away from the heating network 2 is connected to the heating tank. The heating tank is used to heat the heat-carrying medium output by the output pipe 203. In this embodiment, the heating tank heats the heat-carrying medium by an electric heating wire when heating the heat-carrying medium. A liquid storage chamber is also provided in the heating device 3. The liquid storage chamber is spaced apart from the heating tank. The liquid storage chamber is used to store the heat-carrying medium heated by the heating tank. The end of the input pipe away from the heating network 2 is connected to the liquid storage chamber. A delivery pump is installed in the liquid storage chamber. The delivery pump is used to deliver the heat-carrying medium in the liquid storage chamber to the input pipe. The input pipe is used to deliver the heat-carrying medium to the heating network 2. The specific structure of the liquid storage chamber and the delivery pump is the prior art and will not be described here. By providing a liquid storage chamber in the heating device 3 , the heating device 3 can adjust the heat medium delivered to the heating network 2 according to the actual demand of the heating network 2 for the heat medium.

[0024] The heating device 3 is located on the side of the sponge layer 1. Specifically, a placement groove 301 for placing the heating device 3 is opened on the side of the sponge layer 1, and the heating device 3 is engaged with the placement groove 301. An isolation layer is bonded to the side wall of the placement groove 301. Preferably, the isolation layer is high-density pearl cotton in this embodiment. The isolation layer is used to isolate the water vapor in the sponge layer 1 to ensure the safety of the heating device 3 in the placement groove 301.

[0025] A fixing groove 101 is provided on the upper surface of the sponge layer 1. The fixing groove 101 is recessed with the upper surface of the sponge layer 1. The size and distribution position of the fixing groove 101 match the heating pipe network 2. The heating pipe network 2 is embedded in the fixing groove 101. The fixing groove 101 is used to fix the position of the heating pipe network 2. A fabric layer 4 is also laid on the upper surface of the sponge layer 1. The fabric layer 4 completely covers the upper surface of the sponge layer 1. The thickness of the fabric layer 4 is 10-30 mm. Specifically, the thickness of the fabric layer 4 in this embodiment is 20 mm. In this embodiment, the fabric layer 4 is made of a silica gel composite material. In other embodiments, the fabric layer 4 can also be made of other materials. The heating pipe network 2 will not be felt during use, which improves the comfort of the mattress while reducing the pressure on the heating pipe network 2 during use, ensuring the smooth flow of the heat-carrying medium in the heating pipe network 2.

[0026] The heating transverse pipe 201 and the heating longitudinal pipe 202 in the heating pipe network 2 are both rubber hoses, wherein the inner walls of the heating transverse pipe 201 and the heating longitudinal pipe 202 are integrally formed with a plurality of supporting protrusions 204, as shown in the attached Figure 2As shown, a plurality of support protrusions 204 are staggeredly distributed along the circumferential direction of the inner wall of the heating transverse tube 201 or the heating longitudinal tube 202, and two adjacent support protrusions 204 are spaced apart from each other. The support protrusion 204 is a cone, and the central axis of the support protrusion 204 is located on the diameter of the heating transverse tube 201 or the heating longitudinal tube 202, and the height of the support protrusion 204 along its own central axis is less than the diameter of the heating transverse tube 201 or the heating longitudinal tube 202. When in use, the heating pipe network 2 can be sunken along with the sponge layer 1 to facilitate the flow of the heat carrier medium. At the same time, by arranging the support protrusions 204 in the heating pipe network 2, when the heating pipe network 2 is squeezed and deformed, the pipe wall of the heating pipe network 2 can ensure that the heat carrier medium can flow smoothly in the heating pipe network 2 under the action of the support protrusions 204, avoiding the blockage of the heating pipe network 2 and improving the safety of the heating pipe network 2.

Preferably, in this embodiment, the temperature sensor is a temperature sensor of model E52-P5AY-40, and the pressure sensor is a pressure sensor of model FST800-1500. The control unit is electrically connected to the detection unit and the heating device 3, and the control unit is used to control the operation of the delivery pump according to the detection value of the pressure sensor. Specifically, when the pressure sensor detects the pressure value of the heat-carrying medium at the input port of the heating pipe network 2, it analyzes whether the heating pipe network 2 is squeezed and blocked. When the heating pipe network 2 is squeezed and blocked, the operation of the delivery pump is controlled to avoid excessive pressure in the heating pipe network 2 causing damage to the heating pipe network 2; the control unit also adjusts the heating power of the heating device 3 according to the detection result of the temperature sensor, and the control unit is also used to adjust the heating power of the heating device 3 according to the user's adjustment temperature, wherein the control content of the control unit on the delivery pump and the heating device 3 is the prior art, which will not be repeated here. The processing chip of the control unit may be a microprocessor or a single-chip microcomputer. Preferably, in this embodiment, a single-chip microcomputer of model STM32F103 is selected as the processing chip of the control unit.

[0028] The specific implementation process is as follows:

[0029] When the mattress needs to be heated, the heat medium is heated by the heating device 3, and the heated heat medium is transported to the heating pipe network 2 through the input pipe, and the heat medium is filled in the heating pipe network 2. After the heat medium radiates heat on the surface of the mattress to heat the surface of the mattress, the heat medium is transported back to the heating device 3 through the output pipe 203 for reheating. When the heat medium is filled in the heating pipe network 2, the sponge layer 1 is squeezed by the human body and some areas are sunken. Under the action of gravity, the heat medium preferentially flows to the sunken area of ​​the sponge layer 1, and focuses on heating the use area of ​​the mattress.

[0030] Compared with the prior art, the present solution connects the heating pipe network 2 laid on the sponge layer 1 in a vertical and horizontal manner, so that the heat-carrying medium in the heating pipe network 2 can flow horizontally and vertically on the surface of the sponge mattress, ensuring that when a depression appears on the surface of the sponge layer 1, the heating pipe network 2 in the depression area can be fully filled with the heat-carrying medium for heating, thereby improving the pertinence when heating the mattress surface. Furthermore, by arranging the output pipe 203 in the middle of one side of the sponge layer 1, after the heat-carrying medium is filled in the heating pipe network 2 in the depression area of ​​the sponge layer 1, the output pipe 203 can timely output the heat-carrying medium in the heating pipe network 2 through overflow, so that the flow of the heat-carrying medium can be adjusted according to the actual position on the mattress, ensuring that the filling of the heat-carrying medium matches the actual situation.

[0031] The above are only embodiments of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
