Description

Technical Field

[0001] This invention relates to the field of heated and cooled mattress technology, specifically a mattress structure applied to heated and cooled mattresses. Background Technology

[0002] As a sleep aid device with temperature regulation, the core requirement of a heated and cooled mattress is to provide a comfortable sleep environment for users through uniform temperature conduction. However, existing heated and cooled mattresses still have many technical defects in practical applications, which seriously affect user experience and product practicality.

[0003] In terms of temperature regulation, existing heated and cooled mattresses generally adopt a long-distance single-tube circulation temperature conduction structure design. This structure results in significant energy loss of the refrigerant or heating medium during circulation, making the cooling or heating efficiency of the main use area of ​​the mattress (i.e., the area that the user's body mainly contacts) low and unable to quickly reach the set temperature. At the same time, due to the excessively long single-tube circulation path, the refrigerant or heating medium is prone to accumulation at the beginning / end of the circulation (i.e., the edge area of ​​the mattress), causing the edge area temperature to be too low or too high, forming a significant regional temperature difference and affecting sleep comfort.

[0004] In terms of energy consumption and durability, long-distance single-pipe circulation structures place high demands on the power of the drive components (water pumps). The water pumps need to continuously output large power to maintain the effective circulation of refrigerant or heat medium. This not only leads to a low energy efficiency ratio and increases user costs, but also exacerbates the wear and aging of the water pump due to long-term high-load operation, significantly shortening the service life of the water pump and even the entire mattress, and reducing product reliability.

[0005] In terms of mattress support and comfort, most existing heated and cooled mattresses use traditional fiber cotton as the covering material, which can cause discomfort when combined with the tubing of the heated and cooled mattress.

[0006] In summary, the existing heated and cooled mattresses have technical deficiencies in terms of temperature uniformity, energy efficiency, durability, and support comfort, which can no longer meet users' needs for high-quality sleep equipment. There is an urgent need to propose a heated and cooled mattress that can solve the above problems. Summary of the Invention

[0007] To address the aforementioned shortcomings, this invention proposes a mattress structure for use in heated and cooled mattresses, solving the problems of low comfort, insignificant cooling effect in key areas, and short service life of existing heated and cooled mattresses.

[0008] To achieve this objective, the present invention adopts the following technical solution: A mattress structure for use in a hot / cold mattress includes a mattress body, a water distribution connector, and several flow pipes; The surface of the pad is provided with a groove structure; The water distribution connector includes an inlet pipe and an outlet pipe. A plurality of branch pipes are arranged at intervals along the length of the inlet pipe on one side, and a plurality of return branch pipes are arranged at intervals along the length of the outlet pipe on one side. Each of the plurality of branch pipes corresponds to one of the plurality of return branch pipes. The branch pipes are connected to the corresponding return branch pipes through the flow pipes, and each flow pipe is embedded in the groove structure to form a U-shaped pipe. Several flow pipes form several U-shaped pipes of different sizes, and several U-shaped pipes are nested in order from smallest to largest.

[0009] Preferably, the groove structure includes a plurality of longitudinal grooves, a plurality of transverse grooves, and a plurality of receiving grooves, wherein the width of the longitudinal grooves and the transverse grooves is smaller than the maximum width of the receiving grooves; The longitudinal grooves are arranged along the width direction of the pad, and a plurality of the longitudinal grooves extend along the length direction of the pad and penetrate the pad. The transverse grooves are spaced apart along the length direction of the pad, and a plurality of transverse grooves extend along the width direction of the pad and penetrate the pad. The pad has corresponding receiving grooves below the longitudinal grooves and the transverse grooves, and the receiving grooves are respectively connected to the bottom of the longitudinal grooves or the transverse grooves.

[0010] Preferably, the pad is a sponge pad, and the longitudinal groove, the transverse groove and the receiving groove are all formed by CNC cutting machine. The depth of the longitudinal groove and the transverse groove is 3mm-15mm and the width is 3mm-12mm.

[0011] Preferably, the receiving groove is a teardrop-shaped groove or a circular groove.

[0012] Preferably, the pad is divided into a tail section, a middle section, and a head section along its length, and a plurality of the transverse grooves are provided only in the tail section and the head section.

[0013] Preferably, the surface of the pad body has a connector mounting groove in the middle of the tail area, and the two sides of the connector mounting groove are respectively connected to the transverse groove.

[0014] Preferably, the water distribution connector is located in the middle of the tail section of the pad body, the inlet pipe and the outlet pipe are arranged parallel to each other and aligned, and a plurality of the branch pipes and a plurality of return pipes are arranged opposite each other; the diameter of the inlet pipe is larger than the diameter of the branch pipes, the diameter of the outlet pipe is larger than the diameter of the return pipes, and the diameter of the flow pipes is smaller than the diameters of the inlet pipe and the outlet pipe; the vertical branches of the U-shaped pipe are arranged along the length of the pad body.

[0015] Preferably, it further includes a fabric layer that covers the surface of the pad.

[0016] Preferably, the number of branch pipes and return pipes is not less than three, and the number of flow pipes is not less than three.

[0017] Preferably, it further includes an inlet extension pipe and an outlet extension pipe, one end of the inlet extension pipe being connected to the inlet pipe, the other end of the inlet extension pipe being connected to the outlet pipe of the hot and cold mattress main unit, one end of the outlet extension pipe being connected to the outlet pipe, and the other end of the outlet extension pipe being connected to the return water pipe of the hot and cold mattress main unit.

[0018] The technical solution of the present invention can include the following beneficial effects: by combining the flow pipe settings of several U-shaped pipes, multiple parallel flows are achieved, effectively reducing the output pressure of the water pump in the heating and cooling unit. Compared with the traditional long-distance single-pipe circulation, the above design allows the water pump to maintain normal operation without high power, which not only extends the service life of the water pump but also improves energy efficiency. In addition, at the physical contact level, the embedded design of the flow pipe completely eliminates the discomfort of being poked, making the contact surface more flat and comfortable. At the temperature control level, the U-shaped pipe settings make the cooling / heating effect of the key area (center) more prominent, while the temperature of the edge area is more balanced, providing users with a better comfort experience.

Detailed Implementation

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this invention, it should be understood that the terms "length", "middle", "upper", "lower", "left", "right", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] like Figures 1-5 As shown, the present invention proposes a mattress structure for use in a hot and cold mattress, comprising a mattress body 1, a water distribution connector 2, and several flow pipes 3; The surface of the pad 1 is provided with a groove structure 11; The water distribution connector 2 includes an inlet pipe 21 and an outlet pipe 22. A plurality of branch pipes 23 are arranged at intervals along the length of the inlet pipe 21 on one side. A plurality of return branch pipes 24 are arranged at intervals along the length of the outlet pipe 22 on one side. The plurality of branch pipes 23 correspond one-to-one with the plurality of return branch pipes 24. The branch pipes 23 are connected to the corresponding return branch pipes 24 via flow pipes 3, and each flow pipe 3 is embedded in the groove structure 11, forming a U-shaped pipeline (e.g., Figure 5 As shown), several of the flow pipes 3 form several U-shaped pipes of different sizes, and the several U-shaped pipes are nested in sequence from small to large.

[0025] The present invention proposes a mattress structure for use in a heated and cooled mattress. The circulation tube 3 is embedded in the groove structure 11 of the mattress body 1 to avoid direct contact with the human body, prevent the human body from being irritated, eliminate the feeling of foreign objects, and improve the comfort of the heated and cooled mattress. At the same time, by reducing the contact between the circulation tube 3 and the outside air, the generation of condensation and energy loss can be reduced, and it has a good heat preservation effect.

[0026] Secondly, the core improvement of this invention lies in the combination of several U-shaped flow pipes 3 to achieve multi-path parallel operation, effectively reducing the output pressure of the water pump in the heating and cooling unit. Compared with the traditional long-distance single-pipe circulation, the above design allows the water pump to maintain normal operation without high power, thus extending the service life of the water pump and improving energy efficiency. In addition, the several U-shaped pipes are nested in order of increasing size, with the smaller U-shaped pipes being short pipes and the larger U-shaped pipes being long pipes. The short pipes have low resistance and high flow rate, providing a stronger water flow to the key areas (the main usage area of ​​the mattress structure - the middle area), making the cooling / heating effect of the middle area of ​​the mattress structure more obvious; the long pipes are responsible for the circulation of the edge areas. The above layout ensures the cooling effect of the main usage area while preventing the edge areas from becoming too cold.

[0027] The mattress structure proposed in this invention, at the physical contact level, completely eliminates discomfort by embedding the circulation tube 3, making the contact surface flatter and more comfortable; at the temperature control level, the cooling / heating effect in the key area (center) is more prominent, while the temperature in the edge area is more even, providing users with a better comfort experience and solving the problems of low user comfort, insignificant cooling effect in key areas, and short service life of existing hot and cold mattresses.

[0028] To further explain, the groove structure 11 includes a plurality of longitudinal grooves 111, a plurality of transverse grooves 112 and a plurality of receiving grooves 113, wherein the width of the longitudinal grooves 111 and the transverse grooves 112 is smaller than the maximum width of the receiving grooves 113. The longitudinal grooves 111 are arranged along the width direction of the pad 1, and a plurality of the longitudinal grooves 111 extend along the length direction of the pad 1 and penetrate the pad 1. The transverse grooves 112 are arranged at intervals along the length direction of the pad 1, and a plurality of the transverse grooves 112 extend along the width direction of the pad 1 and penetrate the pad 1. The pad 1 has receiving grooves 113 respectively below the longitudinal grooves 111 and the transverse grooves 112, and the receiving grooves 113 are respectively connected to the bottom of the longitudinal grooves 111 or the transverse grooves 112.

[0029] The groove structure 11 is divided into a transverse groove 112, a longitudinal groove 111, and a receiving groove 113. The transverse groove 112 and the longitudinal groove 111 are used to provide openings for the flow pipe 3 to be embedded in the receiving groove 113, which can effectively prevent the flow pipe 3 from detaching from the pad 1 and ensure that the pad 1 has good support capacity.

[0030] Furthermore, the pad 1 can be a soft material such as a latex pad, a sponge pad, or a composite fiber cotton pad. Preferably, the pad 1 is a sponge pad 1. The longitudinal groove 111, the transverse groove 112, and the receiving groove 113 are all formed by CNC cutting machine. The depth of the longitudinal groove 111 and the transverse groove 112 is 3mm-15mm, and the width is 3mm-12mm.

[0031] The pad 1, through the arrangement of longitudinal grooves 111 and transverse grooves 112, achieves a grid-like groove structure. In practical applications, the pad 1 can be cut into a grid pattern using a CNC cutting machine according to the actual water channel requirements of the heating / cooling mattress. This process is not only more economical and efficient, but also allows for flexible adjustment of the flow pipe 3's orientation based on specific layout requirements. After cutting, the flow pipe 3 is arranged according to design requirements. The proposed pad 1 provides great flexibility in the arrangement of the flow pipe 3, solving the problem of complex production of existing pads 1 suitable for heating / cooling mattresses.

[0032] Furthermore, the receiving groove 113 can be a teardrop-shaped groove, a circular groove, or a square groove. Preferably, it is a teardrop-shaped groove or a circular groove, which can fit and limit the flow tube 3, extending the service life of the pad 1.

[0033] To further explain, the pad 1 is divided into a tail area 101, a middle area 102 and a head area 103 along its length or width direction, and a plurality of the transverse grooves 112 are only provided in the tail area 101 and the head area 103.

[0034] Preferably, the pad 1 is a one-piece pad 1. However, in other embodiments, the pad 1 can also be a spliced ​​pad 1. Specifically, the pad 1 is divided into sections. The tail section 101 and the head section 103 are respectively provided with a transverse groove 112 and a longitudinal groove 111, while the middle section 102 is only provided with a longitudinal groove 111. Compared with the middle section 102, the tail section 101 and the head section 103 can use a higher density sponge pad 1 to provide better deformation resistance, avoid the design of interlaced grooves reducing the service life of the pad 1, and provide users with a better comfort experience. It should be noted that the above-mentioned tail section and head section are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the head section is used for supporting the human head and the tail section is used for supporting the human feet. In specific use, the head section can also be used for supporting the human feet, and the tail section can be used for supporting the human head.

[0035] Preferably, the plurality of transverse grooves 112 located in the tail area 101 are divided into a plurality of transverse first grooves 1121 and a plurality of transverse second grooves 1122, and the interval length between the plurality of transverse first grooves 1121 is smaller than the interval length between the plurality of transverse second grooves 1122. The transverse first groove 1121 is used to accommodate the initial and final sections of the flow pipe 3 and the water distribution connector 2, and the transverse second groove 1122 is used to accommodate the inner transverse section in the U-shaped pipe. The inner transverse section is basically located within the effective use area of ​​the heating and cooling mattress. Through the above-mentioned setting of different intervals, the flow can be effectively and quickly diverted, while avoiding the water flow peristalsis caused by the dense arrangement of inner transverse sections in the use area.

[0036] Furthermore, the surface of the pad 1 has a connector mounting groove 114 in the middle of the tail area 101, and the two sides of the connector mounting groove 114 are respectively connected to the transverse groove 112. The connector mounting groove 114 is used to place the water distribution connector 2, preventing the water distribution connector 2 from protruding completely from the surface of the pad 1, reducing the number of protrusions on the surface of the pad 1, and further improving the user's comfort when using the pad 1.

[0037] To further explain, the water distribution connector 2 is located in the middle of the tail section 101 of the pad body 1, such as... Figure 6 As shown, the inlet pipe 21 and the outlet pipe 22 are arranged parallel to each other and aligned, and a plurality of branch pipes 23 and a plurality of return branch pipes 24 are arranged opposite each other; the diameter of the inlet pipe 21 is larger than the diameter of the branch pipes 23, the diameter of the outlet pipe 22 is larger than the diameter of the return branch pipes 24, and the diameter of the flow pipes 3 is smaller than the diameter of the inlet pipe 21 and the outlet pipe 22; the vertical branches of the U-shaped pipe are arranged along the length direction of the pad body 1.

[0038] The water distribution connector 2 is located in the middle of the tail section 101 of the mattress body 1. The vertical branches of the U-shaped pipe are arranged along the length of the mattress body 1, forming symmetrical loops on the left and right sides. The combination of thick and thin pipes for water supply disperses the water flow, reduces the resistance of the heating and cooling mattress system, reduces the workload of the water pump, and further extends the service life of the water pump. The combination of thick and thin pipes can also further reduce the turbulence of water flow in the usage area, providing a more comfortable experience for highly sensitive individuals.

[0039] In a preferred embodiment, such as Figure 7 As shown, it also includes a fabric layer 4, which covers the surface of the pad 1. The fabric layer 4 provides multiple functions of heat preservation and comfort, while also concealing the groove structure 11 on the surface of the pad 1. In a specific embodiment, the fabric layer 4 can be made of a blend of cotton, Tencel, bamboo fiber, and polyester fiber, which is a breathable, skin-friendly fabric with temperature control properties.

[0040] Furthermore, the number of each of the branch pipes 23 and the return branch pipes 24 is not less than three, and the number of the flow pipes 3 is not less than three. Preferably, the number is four or five. In specific embodiments, both the water distribution connector 2 and the flow pipes 3 can be made of materials such as ABS, PP, and PE.

[0041] Furthermore, the system also includes an inlet extension pipe 5 and an outlet extension pipe 6. One end of the inlet extension pipe 5 is connected to the inlet pipe 21, and the other end is connected to the outlet pipe 22 of the heating / cooling mattress main unit. One end of the outlet extension pipe 6 is connected to the outlet pipe 22, and the other end is connected to the return pipe of the heating / cooling mattress main unit. This achieves connection with the heating / cooling mattress main unit. It should be noted that the mattress structure proposed in this invention is applicable to existing heating / cooling mattress main units on the market.

[0042] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
