Description

Technical Field

[0001] This invention relates to the field of mattress technology, and more specifically to a magnet fixing device for a magnetic therapy mattress with full magnetic field coverage. Background Technology

[0002] Most existing magnetic therapy mattresses use static fixing structures for their magnet fixation devices. For example, the Chinese utility model patent CN223913794U discloses a magnetic therapy device fixing device for a magnetic therapy mattress. This patent discloses a multi-directional fixing structure using Velcro, snaps, and elastic cords to connect the magnetic therapy pad to the mattress body, achieving static fixation of the magnet's position. However, this type of static fixing structure has the following drawbacks: the magnet's height and position are fixed, making it impossible to dynamically adjust according to the physiological curvature and support needs of different parts of the body, such as the cervical spine and legs. It is difficult to create a supportive surface or lifting slope that conforms to the human body, affecting both the accuracy of the magnetic therapy effect and reducing user comfort. Summary of the Invention

[0003] The main objective of this invention is to provide a magnetic fixation device for a magnetic therapy mattress with full magnetic field coverage, in order to solve the problem that the existing magnetic therapy device fixation device of the magnetic therapy mattress cannot be dynamically adjusted according to the physiological curvature and support needs of different parts of the human body such as the cervical spine and legs.

[0004] To achieve the above objectives, the present invention provides a magnetic fixing device for a magnetic therapy mattress with full magnetic field coverage, comprising a mattress shell, a flexible layer and a support layer disposed inside the mattress shell, and multiple adjustment units arranged in a matrix between the support layer and the flexible layer. Each adjustment unit includes a guide tube and a telescopic rod; The guide tube is fixedly connected to the support layer. Inside the guide tube, a lifting airbag, a lower magnet part and an upper magnet part are arranged sequentially along its axial direction. One end of the telescopic rod is fixedly connected to the upper magnet part, and the other end of the telescopic rod passes through the guide tube and is connected to a bearing member. The bearing member abuts against the flexible layer. The lower magnet section and the upper magnet section are arranged opposite each other in a manner that repels magnetic forces; Multiple airbags located in the same row are connected to the same air source.

[0005] The magnetic fixation device of the magnetic field line full-coverage magnetic therapy mattress includes a mattress shell, a flexible layer and a support layer inside the mattress shell, and multiple adjustment units are arranged in a matrix between the support layer and the flexible layer. Each adjustment unit includes a guide tube and a telescopic rod; The guide tube is fixedly connected to the support layer. Inside the guide tube, a lifting airbag, a lower magnet part and an upper magnet part are arranged sequentially along its axial direction. One end of the telescopic rod is fixedly connected to the upper magnet part, and the other end of the telescopic rod passes through the guide tube and is connected to a bearing member. The bearing member abuts against the flexible layer. The lower magnet section and the upper magnet section are arranged opposite each other in a manner that repels magnetic forces; Multiple airbags located in the same row are connected to the same air source.

[0006] Preferably, the housing includes an upper housing and a lower housing that are detachably connected, with a support layer disposed in the lower housing and a flexible layer disposed in the upper housing.

[0007] Preferably, the guide tube is made of insulating material and the flexible layer is made of latex material.

[0008] Preferably, the magnet fixing device of the magnetic field line full-coverage magnetic therapy mattress also includes an integrated box, which is fixedly connected to the support layer and located on one side inside the mattress shell, with multiple air sources set inside the integrated box.

[0009] Preferably, each carrier is fixedly connected to an inclined plate on one side, and a connecting airbag is fixedly connected to the inclined plate. The end of the connecting airbag away from the inclined plate is fixedly connected to an adjacent carrier in the same column. Multiple connecting airbags and multiple lifting airbags in the same row are all connected to the same air source.

[0010] Preferably, each air source is connected to a main passage, and the end of the main passage away from the air source is connected to multiple branch passages, which are respectively connected to multiple lifting airbags located in the same row.

[0012] Preferably, the upper housing and the lower housing are detachably connected by a flexible connector.

[0013] Preferably, the gasket is made of silicone rubber.

[0014] The beneficial effects of the above scheme are: This invention achieves synchronized control of the adjustment units by connecting multiple lifting airbags located in the same row to a single air source. When the air source synchronously inflates the lifting airbags in the same row, the airbags in each guide tube expand synchronously, pushing the lower magnet, upper magnet, and telescopic rod to rise synchronously. This causes multiple supporting components in that row to jointly lift the flexible layer, forming a continuous linear raised structure on the mattress surface. This raised structure can be ergonomically designed to form a supporting curved surface at the cervical spine to support the cervical spine and maintain its physiological curvature; or to form a lifting ramp at the leg position, raising the legs higher than the upper body and promoting blood return from the lower limbs. Compared to independently controlling each adjustment unit, the synchronized structure of this invention eliminates the need for complex control logic and numerous independent air paths, reducing system complexity and manufacturing costs while ensuring consistency and synchronicity of movement within the same support area.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below. Example

[0019] like Figures 1 to 7As shown, this embodiment provides a magnetic fixing device for a magnetic therapy mattress with full magnetic field coverage. The device includes a rectangular housing 1. The housing 1 forms the outer contour and protective structure of the entire mattress. In this embodiment, the upper surface of the housing 1 is preferably made of silicone rubber, which has good flexibility and wear resistance, providing reliable protection for the internal structure while improving the user's tactile experience. Specifically, the housing 1 includes a detachably connected upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 are detachably connected by a flexible connector 7, which can be a zipper, Velcro, or snap-on structure. This detachable design facilitates the installation, maintenance, or replacement of internal components. The lower housing 12 has a support layer 3 inside, which serves as the base of the entire device. It is made of a material with a certain rigidity (such as high-density polyurethane board or wood panel) and provides a stable mounting base for multiple adjustment units 4. The upper housing 11 has a flexible layer 2 inside, which is in direct contact with the human body and is preferably made of latex material. Latex materials have excellent elasticity and breathability.

[0020] Multiple adjustment units 4 are arranged in a matrix between the support layer 3 and the flexible layer 2. These adjustment units 4 are neatly arranged in rows and columns, forming a dynamically adjustable support array. A row of adjustment units can be considered as multiple adjustment units 4 arranged along the width direction of the pad shell 1, and a column of adjustment units 4 can be considered as multiple adjustment units 4 arranged along the length direction of the pad shell 1, such as... Figures 5 to 7 As shown, each adjustment unit 4 includes a guide tube 41 and a telescopic rod 42. The guide tube 41 is a hollow cylinder, and its bottom end is fixedly connected to the upper surface of the support layer 3. The guide tube 41 is made of insulating material (such as ABS plastic or nylon) to avoid interfering with the magnetic field generated by the magnet. Inside the guide tube 41, from bottom to top along its axial direction (i.e., vertical direction), there is a lifting airbag 43, a lower magnet part 44, and an upper magnet part 45. The lower end of the telescopic rod 42 is fixedly connected to the top of the upper magnet part 45, and the upper end of the telescopic rod 42 extends upward through the top opening of the guide tube 41 and is connected to a support member 46. The top surface of the support member 46 abuts against the bottom surface of the flexible layer 2. In this embodiment, the support member 46 is a rectangular plate structure with an area larger than the cross-sectional area of ​​the telescopic rod 42, so that the lifting force generated by the telescopic rod 42 can be transmitted to the flexible layer 2 more evenly, avoiding indentation or damage to the flexible layer 2 due to excessive local stress.

[0021] The lower magnet part 44 and the upper magnet part 45 are arranged opposite each other in a magnetically repulsive manner, that is, the magnetic poles on the upper surface of the lower magnet part 44 are the same as the magnetic poles on the lower surface of the upper magnet part 45. For example, if the upper surface of the lower magnet part 44 is the N pole, then the lower surface of the upper magnet part 45 is also the N pole. This arrangement of like poles opposite each other ensures that there is always a repulsive magnetic force between the lower magnet part 44 and the upper magnet part 45. When the lifting airbag 43 is not inflated or is deflated, the lower magnet part 44 may be located at the bottom of the guide tube 41 under the action of its own weight and the gravity of the upper magnet part 45. At this time, the upper magnet part 45 is suspended above the lower magnet part 44 due to magnetic repulsion, and the telescopic rod 42 and the support member 46 are in a lower position. When the lifting airbag 43 inflates, it pushes the lower magnet 44 upward. During the ascent, the magnetic repulsion between the lower magnet 44 and the upper magnet 45 increases further, thus jointly propelling the upper magnet 45, the telescopic rod 42, and the support member 46 upward. This composite drive method of "airbag + magnetic repulsion" not only provides a larger lifting force but also utilizes the nonlinear characteristics of magnetic repulsion to make the lifting process smoother and more elastically buffered, avoiding rigid impacts and improving the user experience.

[0022] To achieve synchronized adjustment across rows, this device connects the lifting airbags 43 of multiple adjustment units 4 located in the same row to the same air source. For example, in the width direction of the mattress, each row of adjustment units 4, corresponding to different areas of the human body such as the cervical spine, waist, and legs, is equipped with an independent air source. When the mattress needs to be adjusted to the "cervical spine support curve" mode, the controller activates the row or multiple air sources corresponding to the cervical spine area, simultaneously inflating all the lifting airbags 43 in that row. These lifting airbags 43 expand synchronously, pushing their respective lower magnet 44, upper magnet 45, telescopic rod 42, and support member 46 to rise synchronously, thereby forming a continuous and uniformly high linear protrusion on the mattress surface. This protrusion perfectly conforms to the physiological curvature of the human cervical spine, providing precise and comfortable support. Similarly, when the mattress needs to be adjusted to the "leg lift ramp" mode, multiple air sources corresponding to the calf and thigh areas can be activated sequentially or simultaneously. This causes the adjustment units 4 of these air sources to rise gradually or synchronously from the ankle to the knee, forming a smooth lift ramp on the mattress surface. This effectively promotes blood flow back to the lower limbs and relieves leg fatigue. An air pump can be used as the air source.

[0023] To achieve centralized management of the gas source and pipelines, this device also includes an integrated housing 6. The integrated housing 6 is fixedly connected to the support layer 3 and is located on one side of the housing 1 (e.g., at the foot of the bed). Multiple gas sources (such as miniature air pumps or gas cylinders) and their corresponding control valves are integrated within the integrated housing 6. This integrated design not only saves internal space and facilitates installation and maintenance, but also effectively reduces noise generated by the gas sources during operation, minimizing interference with the user.

[0024] Please refer to Figure 3 In a preferred embodiment, each support member 46 has a slanted plate 461 fixedly connected to one side. A connecting airbag 462 is fixedly connected to the slanted plate 461. The end of the connecting airbag 462 away from the slanted plate 461 is fixedly connected to an adjacent support member 46 in the same column. Furthermore, multiple connecting airbags 462 and multiple lifting airbags 43 in the same row are all connected to the same air source. This structural design aims to solve the problem of gaps or discontinuities between adjacent support members 46 in the column direction that may occur due to single-row lifting. When the air source inflates the lifting airbags 43 in a certain row, it also simultaneously inflates the connecting airbags 462 in that row. After inflation, the connecting airbags 462 expand laterally, spreading the adjacent support members 46 in the same column apart, maintaining continuous and stable support in the column direction, thereby forming a continuous raised curved surface or slant on the mattress surface, further improving the uniformity and integrity of the support, and avoiding local "discontinuity".

[0025] Regarding gas path connections, such as Figure 4 As shown, each air source is connected to a main passage (not shown in the figure). The end of the main passage furthest from the air source is connected to multiple branch passages (not shown in the figure), each branch passage corresponding to one of the multiple lifting airbags 43 located in the same row. The branch passages are flexible hoses (such as PU hoses or silicone hoses) to accommodate minor displacements that may occur during the lifting and lowering of the adjustment unit 4. Each main passage is equipped with a pressure relief valve. When it is necessary to release the support mode and restore the flexible layer 2 to its flat state, the controller opens the pressure relief valve, allowing the gas in the lifting airbag 43 and the connecting airbag 462 to be quickly discharged through the main passage and the pressure relief valve. The lifting airbag 43 contracts, the lower magnet part 44 descends, and the flexible layer 2 subsequently returns to its flat state.

[0026] In summary, the magnetic fixation device of the magnetic field line full-coverage magnetic therapy mattress of the present invention, through the matrix arrangement of the adjustment units 4 and the use of a row-linked controlled airbag drive method, combined with magnetic repulsion suspension support, not only achieves dynamic adjustment of the mattress surface shape, enabling the formation of precise support curves or lifting slopes according to the needs of different parts of the body, but also features a compact structure, simple control, and stable operation, significantly improving user comfort while ensuring the accuracy of the magnetic therapy effect. Furthermore, the inclusion of connecting airbags 462 further ensures the continuity and integrity of the support surface.

[0027] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
