Description

Technical Field

[0001] The present invention relates to the field of health care, in particular to a magnetic mattress. Background Art

[0002] Magnetic therapy is a method of treating certain diseases by applying artificial magnetic fields to the body's meridians, acupuncture points, and affected areas. Hospital-provided magnetic therapy equipment is effective for hypertension, arthritis, headaches, insomnia, coronary heart disease, gastroenteritis, hemifacial spasms, sprains, cervical spondylosis, and more. It's just that for some diseases, it's a direct treatment, while for others, it's an auxiliary treatment. On May 11, 2011, the State Food and Drug Administration issued the "Guiding Principles for the Technical Review of Magnetic Therapy Product Registration" (hereinafter referred to as the "Guiding Principles"), which stated: "Magnetic fields can regulate the body's biomagnetic field, generate induced microcurrents, change cell membrane permeability, alter the activity of certain enzymes, dilate blood vessels, and accelerate blood flow, thereby achieving auxiliary therapeutic effects such as pain relief and swelling reduction."

[0003] Therefore, a mattress with magnetic therapy function has been developed in the prior art, which is used for continuous magnetic therapy during the user's sleep, thereby achieving the effect of promoting human health and improving sleep quality. Figure 1 As shown, a plurality of magnets 102 are evenly arranged at the bottom of the mattress body 101. Those skilled in the art know that the magnetic field distribution of the magnets 102 is roughly as follows: Figure 1 As shown by the dashed line in the figure (showing only the portion above magnet 102), the magnetic field strength decreases rapidly with increasing distance from magnet 102. Therefore, the magnetic field strength within the x1 range is significantly stronger than the magnetic field strength within the x2 range. Consequently, during use of existing magnetic therapy mattresses, changes in the user's sleeping position can lead to extremely unstable magnetic field strength, weakening the therapeutic effect.

[0004] In order to ensure the effectiveness of magnetic therapy, how to design a magnetic therapy mattress that can maintain a relatively stable magnetic field strength even when the user's sleeping position changes is one of the problems that needs to be solved urgently. Summary of the Invention

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a magnetic mattress that can maintain a relatively stable magnetic field strength after the user's sleeping position changes, thereby ensuring the stability of the magnetic therapy effect.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A magnetic mattress comprises a mattress base and a mattress body located above the mattress base, a cavity for accommodating a magnet being provided between the mattress base and the mattress body, a plurality of air bags being horizontally provided on the top of the mattress body, a magnet and an adjustment mechanism for driving the magnet to move being provided between any two adjacent air bags along the width direction of the mattress body within the cavity; when the pressure borne by any air bag is greater than the pressure borne by the air bag adjacent to it in the width direction, the adjustment mechanism drives the magnet to move toward the side of the air bag borne by the greater pressure.

[0008] Furthermore, the adjustment mechanism includes a sliding rod that is respectively connected to the bottom of two adjacent airbags in a sliding and sealing manner, the bottom of the sliding rod extends into the cavity, and a support seat is provided in the cavity to provide an upward support force for the sliding rod; it also includes a telescopic rod, the two ends of the telescopic rod are respectively hinged to the middle of the two sliding rods; the magnet is sleeved on the telescopic rod.

[0009] Furthermore, the telescopic rod includes a first hinge seat, a second hinge seat, and a telescopic rod body. The first hinge seat and the second hinge seat are respectively hinged to the middle part of the sliding rod at the bottom of two adjacent airbags. The free ends of the first hinge seat and the second hinge seat are respectively provided with a first sliding groove, and the two ends of the telescopic rod body are respectively slidably connected to the first sliding grooves of the first hinge seat and the second hinge seat.

[0010] Furthermore, first springs are provided on both sides of the telescopic rod and are used to apply a force to the magnet toward the middle position of the telescopic rod.

[0011] Furthermore, the first end of the spring presses against one side of the magnet, and the second end presses against the free end of the first hinge seat or the second hinge seat.

[0012] Furthermore, the support seat includes a boss arranged at the bottom of the cavity, and a second sliding groove is provided on the top of the boss for the sliding rod to slide. A second spring is provided in the second sliding groove, and the first end of the second spring is against the bottom of the second sliding groove, and the second end is against the bottom of the sliding rod.

[0013] Furthermore, the airbag is formed by a frame with an upper opening provided on the upper surface of the mattress body and a flexible member above the mattress body being sealed and connected.

[0014] Furthermore, the flexible member is made of TPU laminated fabric or PVC laminated fabric.

[0015] Furthermore, the flexible member is provided with a downwardly extending connecting portion at an edge position corresponding to the frame, the upper edge of the frame is provided with a slot for accommodating the connecting portion, sealant is provided between the connecting portion and the slot, and each side of the frame is also provided with at least one fixing bolt that passes through both the side of the frame and the connecting portion.

[0016] Furthermore, a downwardly extending reinforced sealing portion is provided at the bottom of the airbag corresponding to the outer edge of the slide bar.

[0017] The present invention has the following advantages compared to the prior art:

[0018] The operating principle of the present invention is that the pressure differential between the two airbags activates the bottom adjustment mechanism, driving the magnets toward the side of the airbag experiencing greater pressure. Therefore, when a user lies on the mattress, the magnets located outside the user's body edge will shift in response to the pressure differential created by the body on the airbags, moving toward the body's side. This creates a denser distribution of magnets along the body's contours, strengthening the magnetic field locally, particularly in the torso. Furthermore, as the user's sleeping position changes, the pressure on the magnetic airbags changes accordingly, causing the magnets to shift accordingly, thus maintaining a relatively stable magnetic field.

[0038] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0039] Example 1:

[0040] See also Figure 2 This embodiment provides a magnetic mattress, including a mattress base 1 and a mattress body 2 located above the mattress base 1, and a cavity 3 for placing a magnet 5 is provided between the mattress base 1 and the mattress body 2.

[0041] The mattress body 2 is horizontally arranged with several air cells 4 on top. When a user lies on the mattress, the mattress remains essentially stationary along its length. However, their position across the width of the mattress changes with their sleeping posture. To address this, this embodiment includes magnets 5 and an adjustment mechanism 6 for driving the movement of these magnets within the cavity 3, between any two adjacent air cells 4 along the width of the mattress body 2.

[0042] When the pressure on any air cell 4 is greater than that on its adjacent air cell in the width direction, the adjustment mechanism 6 drives the magnet 5 toward the air cell 4 experiencing the greater pressure. This allows the magnet located near the user's body to move toward the user as they lie on the mattress. If the user's sleeping position changes, the air cell experiencing the primary pressure also shifts, causing the corresponding magnet to shift with the body's swaying.

[0043] like Figure 3 As shown, to achieve displacement of the magnet 5 in response to pressure changes in the airbags 4, the adjustment mechanism 6 includes a slide rod 61 that is slidably and sealingly connected to the bottoms of two adjacent airbags (including the first airbag 4a and the second airbag 4b). The bottom of the slide rod 61 extends into the cavity 3, and a support seat 62 is provided in the cavity 3 to provide upward support for the slide rod 61. The adjustment mechanism 6 also includes a telescopic rod 63, the ends of which are hinged to the middle portions of the two adjacent slide rods 61; the magnet 5 is mounted on the telescopic rod 63.

[0044] In the above embodiment, the magnet 5 is mounted using the telescopic rod 63 in order to adapt to the height difference between two adjacent slide rods 61, which will cause the distance between the two hinge points to change. Figure 3 As shown, the telescopic rod 63 includes a first hinge seat 631, a second hinge seat 632, and a telescopic rod body 633; ​​the first hinge seat 631 and the second hinge seat 632 are respectively hinged to the middle part of the slide rod 61 at the bottom of two adjacent airbags 4, and the free ends of the first hinge seat 631 and the second hinge seat 632 are respectively provided with a first sliding groove, and the two ends of the telescopic rod body 633 are respectively slidably connected to the first sliding grooves of the first hinge seat 631 and the second hinge seat 632.

[0045] The pressure conditions of two adjacent airbags (including the first airbag 4a and the second airbag 4b) mainly include the following three types:

[0046] Case 1: If Figure 3 As shown, the first airbag 4a and the second airbag 4b are not subjected to external pressure. At this time, the two adjacent sliding rods 61 maintain the same height, the telescopic rod 63 maintains a horizontal state, and the magnet 5 is located in the middle of the telescopic rod 63.

[0047] Case 2: If Figure 8 As shown, the first airbag 4a and the second airbag 4b are both subjected to external pressure, and the external pressures on the two are basically equal (for example, the human body part 8 is exactly in the middle of the first airbag 4a and the second airbag 4b). At this time, the two adjacent sliding rods 61 also maintain the same height, the telescopic rod 63 remains horizontal, and the magnet 5 is located in the middle of the telescopic rod 63.

[0048] In the above two cases, in order to ensure that the magnet 5 can be located in the middle of the telescopic rod 63, a first spring 64 for applying a force to the magnet 5 toward the middle position of the telescopic rod is provided on both sides of the telescopic rod 63. The first spring 64 of this embodiment is a compression spring, and the first end of the first spring 64 is pressed against one side of the magnet 5, and the second end is pressed against the free end of the first hinge seat 631 or the second hinge seat 632.

[0049] Case 3: If Figure 9 As shown, the first airbag 4a and the second airbag 4b are both subjected to external pressure and the external pressures on the two are not equal (for example, the position of the human body part 8 is biased towards the first airbag 4a), or only one of the airbags is subjected to external pressure, resulting in a height difference between the two adjacent slide bars 61 (the slide bar 61 corresponding to the airbag subjected to greater external pressure is lower), and the telescopic rod 63 is tilted toward the side of the airbag subjected to greater external pressure. At this time, the magnet 5 moves toward the side of the first airbag 4a subjected to greater external pressure, and the magnetic field on the human body part 8 located above the first airbag 4a increases.

[0050] like Figure 3 As shown, in order to support the sliding rod 61, the support seat 62 includes a boss 621 arranged at the bottom of the cavity 3, and the top of the boss 621 is provided with a second sliding groove 622 for the sliding rod 61 to slide, and a second spring 623 is provided in the second sliding groove 622. The first end of the second spring 623 is against the bottom of the second sliding groove 622, and the second end is against the bottom of the sliding rod 61.

[0051] like Figure 4 and Figure 5 As shown, the airbag 4 is formed by a frame 41 with an upper opening provided on the upper surface of the mattress body 2 and a flexible member 42 above the mattress body 2, which is sealed and connected. In order to ensure both the comfort and sealing of the mattress, the flexible member 42 is made of TPU laminated fabric or PVC laminated fabric. It is worth noting that Figure 5 Each frame 41 has two small holes, one for mounting a slide rod 61, and the other for mounting an air nozzle 7, which facilitates inflating the airbag 4 and adjusting the air pressure. It is worth noting that the inflation port of the air nozzle 7 is connected to the outside of the mattress base or mattress body via a connecting pipe, thereby facilitating inflation. For clarity, the connecting pipe for inflation is not shown in the drawings of this embodiment.

[0052] In order to ensure the sealing connection between the flexible member and each upper edge of the frame, the flexible member 42 is provided with a downwardly extending connecting portion 421 corresponding to the edge position of the frame 41, and the upper edge of the frame 41 is provided with a card slot 411 for accommodating the connecting portion 421. A sealant (not shown in the figure) is provided between the connecting portion 421 and the card slot 411. Each side of the frame 41 is also provided with at least one fixing bolt 43 that passes through the side of the frame 41 and the connecting portion 421 at the same time, so as to prevent the flexible member 42 from detaching from the frame 41 when the airbag 4 is under excessive pressure.

[0053] It is worth mentioning that Figure 6 and Figure 7 As shown, to facilitate installation between the flexible member 42 and the frame 41, the flexible member 42 is provided with a first folded edge 44 along the vertical direction on the first side and a second folded edge 46 along the horizontal direction on the second side. During installation, the first folded edge 44 along the vertical direction is first aligned with the inner edge of the frame 41 on the first side of the mattress body 2, and then the fixing bolt 45 is screwed in horizontally. When the airbag 4 inflates, the vertical first folded edge 44 will compress the gap between it and the inner edge of the frame 41, preventing air leakage. Then, along the direction from the first folded edge 44 to the second folded edge 46, the connecting portion 421 is sequentially placed into the slot 411 and the corresponding fixing bolts 43 are screwed in to secure it. Finally, the second folded edge 46 along the horizontal direction on the second side is aligned with the outer wall of the frame 41 on the second side of the mattress body 2, and then the fixing bolt 46 is screwed in vertically.

[0054] Please refer to Figure 4 In order to strengthen the sealing connection strength of the slide rod 61, a downward extending reinforcing sealing portion 611 is provided at the bottom of the airbag 4 corresponding to the outer edge of the slide rod 61. The reinforcing sealing portion 611 is a sleeve that is slidingly and sealingly connected to the slide rod 61.

[0055] Example 2:

[0056] This embodiment also provides a method for adjusting the magnet of an airbag-based magnetic mattress, including the following:

[0057] Please refer to Figure 2 and Figure 3 , a number of air bags 4 are arranged horizontally on the top of the mattress body 2; the bottom of each air bag 4 is slidably and sealedly connected to a slide rod 61, and the bottom of the slide rod 61 extends to the bottom of the mattress body into the cavity 3 for placing the magnet 5; a telescopic rod 63 is arranged between two adjacent slide rods 61 in the width direction of the mattress, and the two ends of the telescopic rod 63 are respectively hinged to the middle parts of the two adjacent slide rods 61; a support seat 62 is provided in the cavity 3 to provide an upward support force for the slide rod 61, and the magnet 5 is mounted on the telescopic rod 63.

[0058] The use of the telescopic rod 63 to mount the magnet 5 is to adapt to the height difference between two adjacent slide bars 61, which will cause the distance between the two hinge points to change. Figure 3 As shown, the telescopic rod 63 includes a first hinge seat 631, a second hinge seat 632, and a telescopic rod body 633; ​​the first hinge seat 631 and the second hinge seat 632 are respectively hinged to the middle part of the slide rod 61 at the bottom of two adjacent airbags 4, and the free ends of the first hinge seat 631 and the second hinge seat 632 are respectively provided with a first sliding groove, and the two ends of the telescopic rod body 633 are respectively slidably connected to the first sliding grooves of the first hinge seat 631 and the second hinge seat 632.

[0059] According to the different stress conditions of two adjacent airbags in the width direction of the mattress, this adjustment method has the following three states:

[0060] 1. If Figure 3 As shown, when two adjacent airbags are not subjected to external pressure, the two adjacent sliding rods 61 maintain the same height, the telescopic rod 63 maintains a horizontal state, and the magnet 5 is located in the middle of the telescopic rod 63.

[0061] 2. If Figure 8 As shown, when the two adjacent airbags are both subjected to external pressure, and the external pressures on both are basically equal (for example, the human body part 8 is exactly in the middle of the first airbag 4a and the second airbag 4b), the two adjacent sliding rods 61 also maintain the same height, the telescopic rod 63 remains horizontal, and the magnet 5 is located in the middle of the telescopic rod 63.

[0062] 3. If Figure 9 As shown, when two adjacent airbags are both subjected to external pressure and the external pressure on one of the airbags is significantly greater than the external pressure on the other airbag, or when only one of the airbags is subjected to external pressure, a height difference occurs between the two adjacent slide bars 61 (the slide bar 61 corresponding to the airbag subjected to greater external pressure is lower), and the telescopic rod 63 tilts toward the side of the airbag subjected to greater external pressure. At this time, the magnet 5 moves toward the side of the first airbag 4a subjected to greater external pressure, and the magnetic field on the human body part 8 located above the first airbag 4a increases.

[0063] In order to ensure that the magnet 5 can be located in the middle of the telescopic rod 63 in the first two states, a first spring 64 for applying a force to the magnet 5 toward the middle position of the telescopic rod is provided on both sides of the telescopic rod 63. The first spring 64 of this embodiment is a compression spring, and the first end of the first spring 64 is pressed against one side of the magnet 5, and the second end is pressed against the free end of the first hinge seat 631 or the second hinge seat 632.

[0064] In this embodiment, the airbag 4 and the support base 62 are the same as those in the previous embodiment and will not be described in detail here.

[0065] Example 3:

[0066] Based on the magnetic mattress of Example 1, this embodiment further proposes a method for manufacturing a magnetic mattress based on airbags, which specifically includes the following steps:

[0067] S1. Forming a plurality of frames 41 arranged horizontally on the mattress body 2;

[0068] S2. Lay the flexible member 42 on the mattress body 2, so that each frame 41 is sealed and connected with the flexible member 42 to form a plurality of air cells 4 arranged in a horizontal direction;

[0069] S3. Install support bases 62 on the mattress base 1 at positions corresponding to each airbag;

[0070] S4. Vertically set the slide rod 61 on the support base 62. At the same time, set the magnet 5 on the telescopic rod 63, and respectively connect the two ends of the telescopic rod 63 to the middle of the two adjacent slide rods 61 to form a hinge structure.

[0071] S5, such as Figure 12 As shown, the mattress body 2 with the airbag 4 formed in S2 is placed on the mattress base 1, and the upper end of the slide rod 61 is connected to the airbag 4 in a one-to-one sliding and sealing manner;

[0072] S6. Inflate the airbags 4 to make the air pressure in all the airbags 4 equal.

[0073] Please refer to Figure 6 、 Figure 7 and Figure 10 The specific process for sealing the frame 41 and the flexible member 42 in step S2 is as follows: First, align the first vertical fold 44 with the inner edge of the frame 41 on the first side of the mattress body 2. Then, screw in the fixing bolt 45 horizontally. When the airbag 4 inflates, the vertical first fold 44 will compress the gap between it and the inner edge of the frame 41, preventing air leakage. Then, from the first fold 44 to the second fold 46, sequentially insert the connecting portion 421 into the slot 411 and screw in the corresponding fixing bolt 43 to secure it. Finally, align the second horizontal fold 46 on the second side with the outer wall of the frame 41 on the second side of the mattress body 2, and then screw in the fixing bolt 46 vertically.

[0074] Please refer to Figure 11 The specific method of installing the sliding rod 61 and the telescopic rod 63 in step S4 is as follows:

[0075] The telescopic rod 63 includes a first hinge seat 631, a second hinge seat 632, and a telescopic rod body 633; ​​the first hinge seat 631 and the second hinge seat 632 are respectively hinged to the middle portion of the slide rod 61 at the bottom of two adjacent airbags 4, and the free ends of the first hinge seat 631 and the second hinge seat 632 are respectively provided with a first sliding groove, and the two ends of the telescopic rod body 633 are respectively slidably connected to the first sliding grooves of the first hinge seat 631 and the second hinge seat 632;

[0076] In order to adapt to the length of the telescopic rod 63 and the distance between the two adjacent sliding rods 61, when installing the telescopic rod 63, the first hinge seat 631 is first hinged to the sliding rod 61 installed on the support seat 62, and then the first end of the telescopic rod body 633 is slid to the bottom of the first slide groove of the first hinge seat 631, and then the second hinge seat 632 is hinged to the other sliding rod 61 that is not installed on the support seat 62. While the sliding rod 61 is downwardly installed on the support seat 62, the second hinge seat 632 is sleeved on the second end of the telescopic rod body 633 to finally complete the installation.

[0077] In order to ensure that the magnet 5 can be located in the middle of the telescopic rod 63 under normal circumstances, a first spring 64 is provided on both sides of the magnet 5 on the telescopic rod 63 for applying a force to the magnet 5 toward the middle position of the telescopic rod. The first spring 64 of this embodiment is a compression spring, and the first end of the first spring 64 is pressed against one side of the magnet 5, and the second end is pressed against the free end of the first hinge seat 631 or the second hinge seat 632.

[0078] Therefore, while the magnet 5 is sleeved in S4 , the first springs 64 are also sleeved on both sides of the magnet 5 .

[0079] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
