Abstract

This invention relates to the field of magnetic therapy technology and discloses a magnetic therapy bed with a multi-point dense magnetic field. The bed comprises a shell, several electromagnetic devices housed within the shell, a mattress laid on the upper surface of the shell, and a control device electrically connected to the electromagnetic devices. Each electromagnetic device includes a frame, coils wound around the frame, and magnetic needles passing through mounting holes in the hollow frame. The top wall of the shell has a clearance opening exposing the top surface of the frame. A pressure sensor is located on the top surface of the frame and is electrically connected to the control device. The lower the pressure sensed by the pressure sensor, the higher the operating power of the electromagnetic devices controlled by the control device. During use, the protrusions on the back of the body can compress the mattress and apply greater pressure to the pressure sensor, while other concave parts of the back of the body are supported by the mattress but apply less pressure to the pressure sensor. The pressure sensor thus senses different pressures, and the control device adjusts the operating power of the different electromagnetic devices according to the magnitude of the pressure.

Description

Technical Field

[0001] This invention relates to the field of magnetic therapy technology, and in particular to a magnetic therapy bed with a multi-point dense magnetic field. Background Technology

[0002] Current electromagnetic therapy devices can be used on various instruments, while magnetic therapy beds offer users convenient magnetic therapy, promoting blood circulation throughout the body, and are particularly effective for users with poor sleep quality. Patent No. 201720574353.1 discloses a magnetic therapy bed that incorporates at least two magnetic therapy modules within the bed. Each module includes a support member and at least two magnetic therapy components, which generate a magnetic field for the therapy. The magnetic therapy modules are detachably mounted to the bed and cooled by a fan.

[0003] However, when using the aforementioned magnetic therapy bed, the distance and pressure between the user's body and different electromagnetic devices vary as the user lies on the bed. This results in the treatment being more profound on the parts of the body closer to the device under the same magnetic field strength, while the treatment being shallower on the parts of the body further away. The treatment is not uniform and the therapeutic effect is poor.

[0004] Therefore, it is necessary to propose a new type of magnetic therapy bed with multi-point dense magnetic fields to solve the above problems. This addresses the issue that in traditional magnetic therapy beds, the distance and pressure between the user's body and different electromagnetic devices vary when the user is lying on the bed. This results in the treatment being more profound on the parts of the body closer to the device and shallower on the parts farther away, leading to uneven treatment and poor therapeutic effects, even under the same magnetic field strength. Summary of the Invention

[0005] This invention provides a magnetic therapy bed with a multi-point dense magnetic field, which solves the problem that in traditional magnetic therapy beds, the distance and pressure between the user's body and different electromagnetic devices are different when the user is lying on the bed. This results in the treatment being more in-depth on the parts of the body closer to the magnetic field under the same magnetic field strength, while the treatment is shallower on the parts of the body farther away, resulting in uneven treatment and poor treatment effect.

[0006] The technical problem solved by this invention is achieved by the following technical solution: A magnetic therapy bed with a multi-point dense magnetic field includes a shell, several electromagnetic devices disposed within the shell, a mattress laid on the upper surface of the shell, and a control device electrically connected to the electromagnetic devices. The electromagnetic devices include a frame, a coil wound around the frame, and a magnetic needle passing through a mounting hole in the hollow frame. The top wall of the shell has a clearance opening that exposes the top surface of the frame. A pressure sensor is disposed on the top surface of the frame. The pressure sensor is electrically connected to the control device. The lower the pressure sensed by the pressure sensor, the higher the operating power of the electromagnetic devices controlled by the control device.

[0007] Furthermore, it also includes a left-right swing assembly, which is electrically connected to the control device. The left-right swing assembly cooperates with the electromagnetic device to swing left and right. The pressure sensor includes a left pressure sensor and a right pressure sensor. The control device controls the left-right swing assembly to drive the electromagnetic device to swing left and right to adjust, so as to keep the pressure sensed by the left pressure sensor and the right pressure sensor consistent.

[0008] Furthermore, the left and right swinging assembly includes a rotating disk, an upper rack with a downwardly recessed surface on the upper surface of the rotating disk, an upper arc surface with a downwardly recessed surface on the upper surface of the rotating disk, a base fixed to the bottom of the electromagnetic device, an upper motor fixed to the base, an upper gear driven by the upper motor, and bottom pulleys located on both sides of the base. The upper gear meshes with the upper rack, the bottom pulleys abut against the upper arc surface, and the upper motor is electrically connected to the control device.

[0009] Furthermore, it also includes a front-to-back swing assembly, which is electrically connected to the control device. The front-to-back swing assembly cooperates with the electromagnetic device to swing back and forth. The pressure sensor also includes a front pressure sensor and a rear pressure sensor. The control device controls the front-to-back swing assembly to drive the electromagnetic device to swing back and forth to adjust so as to keep the pressure sensed by the front pressure sensor and the rear pressure sensor consistent.

[0010] Furthermore, the front-to-back swing assembly includes a rotating base, a lower rack that protrudes downward from the bottom surface of the rotating disk and is perpendicular to the upper rack, a downwardly recessed lower arc surface on the upper surface of the rotating base, a lower motor fixed on the rotating base, a lower gear driven by the lower motor, wheel supports on both sides of the rotating base, and support wheels on the wheel supports. The lower gear meshes with the lower rack, the support wheels abut against the lower bottom surface of the rotating disk, and the lower motor is electrically connected to the control device.

[0011] Furthermore, it also includes a lifting device, which, together with a control device, is used to lift the electromagnetic device. The lower the pressure sensed by the pressure sensor, the higher the electromagnetic device is raised by the control device.

[0012] Furthermore, the housing includes a head and neck shell, a shoulder and back shell, a waist and hip shell, and a leg shell arranged in sequence. The electromagnetic device is divided into a head and neck module, a shoulder and back module, a waist and hip module, and a leg module, which are respectively disposed in the head and neck shell, the shoulder and back shell, the waist and hip shell, and the leg shell. The control device includes a control box and independent head and neck control boards, shoulder and back control boards, waist and hip control boards, and leg control boards disposed in the control box.

[0013] Furthermore, it also includes a face shell, a support, and a bottom shell. The support has a module mounting cavity for accommodating the housing and a control mounting cavity for accommodating the control box. The bottom shell supports the support. The face shell covers the upper surface of the support and has an opening that exposes the top surface of the housing. The mattress covers the face shell and the surface of the housing.

[0014] Furthermore, the module mounting cavity is formed from the upper surface of the bracket, the control mounting cavity is formed from the lower bottom surface of the bracket and located on one side of the module mounting cavity, and the bottom shell is recessed upward from the bottom surface of the bottom shell to form a control shell for accommodating the control box, and the control shell extends into the control mounting cavity.

[0015] Furthermore, it also includes a cover for sealing the bottom of the control housing and a lock body for locking the cover and the control housing together.

[0016] The beneficial effects of this invention are: This invention comprises a housing, several electromagnetic devices housed within the housing, a mattress placed on the upper surface of the housing, and a control device electrically connected to the electromagnetic devices. Each electromagnetic device includes a frame, a coil wound around the frame, and a magnetic needle passing through a mounting hole in the hollow frame. The top wall of the housing has a recess exposing the top surface of the frame. A pressure sensor is mounted on the top surface of the frame, and the pressure sensor is electrically connected to the control device. The lower the pressure sensed by the pressure sensor, the higher the operating power of the electromagnetic device controlled by the control device. During use, different distances and pressures are generated between the human body and different electromagnetic devices. The protrusion on the back of the human body can compress the mattress and apply greater pressure to the pressure sensor. The other concave parts of the back of the body are supported by the mattress, but the pressure applied to the pressure sensor is relatively small. The pressure sensor thus senses different pressures, and the control device adjusts the working power of different electromagnetic devices according to the pressure level. This allows for greater working power to treat the more distant and less pressured parts of the body, compensating for the insufficient treatment depth. This solves the problem of traditional magnetic therapy beds where the distance and pressure between the body and different electromagnetic devices vary when the user is lying on the bed. As a result, under the same magnetic field strength, the parts of the body closer to the device receive deeper treatment, while the parts farther away receive shallower treatment, resulting in uneven treatment and poor treatment effect.

Detailed Implementation

[0030] To make the objectives, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0031] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 mechanical connection or an electrical 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 according to the specific circumstances. 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 indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] In this invention, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature. The terms "vertical," "horizontal," "left," "right," "above," "below," and similar expressions are for illustrative purposes only and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1, see Figures 1 to 4 A magnetic therapy bed with a multi-point dense magnetic field includes a shell 100, a plurality of electromagnetic devices 200 disposed within the shell 100, a mattress 300 laid on the upper surface of the shell 100, and a control device electrically connected to the electromagnetic devices 200. The electromagnetic device 200 includes a frame 210, a coil 220 wound around the frame 210, and a magnetic needle 240 passing through a mounting hole 230 in the hollow of the frame 210. The top wall of the shell 100 is provided with a relief opening 110 exposing the top surface of the frame 210. A pressure sensor 400 is provided on the top surface of the frame 210. The pressure sensor 400 is electrically connected to the control device. The lower the pressure sensed by the pressure sensor 400, the higher the working power of the electromagnetic device 200 controlled by the control device.

[0035] During use, different distances and pressures are generated between the human body and different electromagnetic devices 200. The protrusions on the back of the human body can compress the mattress 300 and apply greater pressure to the pressure sensor 400, while other concave parts on the back of the human body are supported by the mattress 300 but apply less pressure to the pressure sensor 400. The pressure sensor 400 thus senses the different pressures, and the control device adjusts the working power of different electromagnetic devices 200 according to the pressure magnitude. This enables greater working power to treat the parts of the human body that are further away and under less pressure, thus compensating for the insufficient treatment depth. This solves the problem of traditional magnetic therapy beds where the distance and pressure between the human body and different electromagnetic devices are different when the user is lying on the bed. This results in deeper treatment for parts of the human body that are closer to the device under the same magnetic field strength, while the treatment for parts of the human body that are further away is shallower, less uniform, and less effective.

[0036] Preferably, when the pressure sensed by the pressure sensor is lower than a preset value, it is determined that the human body is not on the electromagnetic device 200, and the electromagnetic device 200 can be turned off, thereby reducing power consumption and increasing service life.

[0037] See Figure 9 The housing 100 includes a head and neck housing 120, a shoulder and back housing 130, a waist and hip housing 140, and a leg housing 150 arranged in sequence. The electromagnetic device 200 is divided into a head and neck module 250, a shoulder and back module 260, a waist and hip module 270, and a leg module 280, which are respectively disposed in the head and neck housing 120, the shoulder and back housing 130, the waist and hip housing 140, and the leg housing 150. The control device includes a control box 800 and independent head and neck control boards 810, shoulder and back control boards 820, waist and hip control boards 830, and leg control boards 840 disposed in the control box 800.

[0038] In use, different control boards individually control their respective modules, providing targeted magnetic therapy to the head and neck, shoulders and back, waist and hips, and legs. Because the distance and pressure between these four body parts and the pressure sensors differ significantly, independent control boards allow each to have a specific operating power range, resulting in more sensitive control, reduced load pressure, increased lifespan, and easier independent disassembly and maintenance without affecting the operation of other modules, thus reducing maintenance costs.

[0039] See Figure 10 and Figure 11 It also includes a face shell 900, a support 910, and a bottom shell 920. The support 910 is provided with a module mounting cavity 911 for accommodating the housing 100 and a control mounting cavity 912 for accommodating the control box 800. The bottom shell 920 supports the support 910. The face shell 900 covers the upper surface of the support 910. The face shell 900 is provided with an opening 930 that exposes the top surface of the housing 100. The mattress 300 covers the face shell 900 and the surface of the housing 100.

[0040] The module mounting cavity 911 can support the housing 100 in a flat state, the face shell 900 further protects the housing 100, and the opening 930 exposes the housing 100, allowing the electromagnetic device 200 to be closer to the mattress 300, making the treatment more in-depth and more energy-efficient.

[0041] The module mounting cavity 911 is formed from the upper surface of the bracket 910, the control mounting cavity 912 is formed from the lower bottom surface of the bracket 910 and located on one side of the module mounting cavity 911, and the bottom shell 920 is recessed upward from the bottom surface of the bottom shell 920 to form a control shell 940 for accommodating the control box 800, and the control shell 940 extends into the control mounting cavity 912.

[0042] The control housing 940 is located at the bottom of the base housing 920, allowing the control box 800 to be installed and removed from below the base housing 920, facilitating the disassembly and maintenance of the control boards inside the control box 800. The control mounting cavity 912 and the module mounting cavity 911 are offset from each other to avoid magnetic field interference between the module and the control board.

[0043] It also includes a cover 950 for sealing the bottom of the control housing 940 and a lock body for locking the cover 950 to the control housing 940. This facilitates the protection of the control box 800 and each control board located at a low position, preventing children from opening it and getting electric shocks, and ensuring electrical safety.

[0044] Example 2, see Figure 5 and Figure 6 Unlike Embodiment 1, this embodiment also includes a left-right swinging component 500, which is electrically connected to the control device. The left-right swinging component 500 works in conjunction with the electromagnetic device 200 to swing left and right. The pressure sensor 400 includes a left pressure sensor 410 and a right pressure sensor 420. The control device controls the left-right swinging component 500 to drive the electromagnetic device 200 to swing left and right to adjust, so as to keep the pressure sensed by the left pressure sensor 410 and the right pressure sensor 420 consistent.

[0045] In use, the left pressure sensor 410 and the right pressure sensor 420 on each electromagnetic device 200 sense the pressure. When one of the pressures is low, it indicates that the human body is further away from the electromagnetic device 200. The control device then controls the left and right swinging component 500 to swing the electromagnetic device 200 to keep the pressure sensed by the left pressure sensor 410 and the right pressure sensor 420 consistent. This allows each electromagnetic device 200 to produce a uniform magnetic therapy effect on the human body. Moreover, because the force on the human body is uniform, the user's body feels more comfortable.

[0046] The left-right swinging assembly 500 includes a rotating disk 510, an upper rack 520 with a downwardly recessed surface on the upper surface of the rotating disk 510, an upper arc surface 530 with a downwardly recessed surface on the upper surface of the rotating disk 510, a base 540 fixed to the bottom of the electromagnetic device 200, an upper motor 550 fixed to the base 540, an upper gear 560 driven by the upper motor 550, and bottom pulleys 570 located on both sides of the base 540. The upper gear 560 meshes with the upper rack 520, the bottom pulleys 570 abut against the upper arc surface 530, and the upper motor 550 is electrically connected to the control device.

[0047] When the left-right swing component 500 swings, the upper motor 550 drives the upper gear 560, and the upper gear 560 moves relative to the upper rack 520, thereby causing the base 540 to move relative to the rotating disk 510, and the electromagnetic device 200 swings left and right accordingly.

[0048] It also includes a front-to-back swing assembly 600, which is electrically connected to the control device. The front-to-back swing assembly 600 works in conjunction with the electromagnetic device 200 to swing back and forth. The pressure sensor 400 also includes a front pressure sensor 430 and a rear pressure sensor 440. The control device controls the front-to-back swing assembly 600 to drive the electromagnetic device 200 to swing back and forth to adjust, so as to keep the pressure sensed by the front pressure sensor 430 and the rear pressure sensor 440 consistent.

[0049] During use, the front pressure sensor 430 and the rear pressure sensor 440 on each electromagnetic device 200 sense the pressure. When one of the pressures is low, it indicates that the human body is further away from the electromagnetic device 200. The control device then controls the front and rear swinging component 600 to swing the electromagnetic device 200 to keep the pressure sensed by the front pressure sensor 430 and the rear pressure sensor 440 consistent. This allows each electromagnetic device 200 to further produce a uniform magnetic therapy effect on the human body. Moreover, because the human body is subjected to uniform force, the user's physical experience is more comfortable.

[0050] The front-to-back swing assembly 600 includes a rotating base 610, a lower rack 620 protruding downwards from the bottom surface of the rotating disk 510 and perpendicular to the upper rack 520, a downwardly recessed lower arc surface 630 on the upper surface of the rotating base 610, a lower motor 640 fixed on the rotating base 610, a lower gear 650 driven by the lower motor 640, wheel supports 660 on both sides of the rotating base 610, and a support wheel 670 on the wheel support 660. The lower gear 650 meshes with the lower rack 620, the support wheel 670 abuts against the lower bottom surface of the rotating disk 510, and the lower motor 640 is electrically connected to a control device.

[0051] When the swing assembly 600 swings, the lower motor 640 drives the lower gear 650, which moves relative to the lower rack 620, thereby causing the rotating disk 510 to move relative to the rotating seat 610, and the electromagnetic device 200 swings back and forth accordingly.

[0052] Example 3, see Figure 7 Unlike Embodiment 1 and Embodiment 2, this embodiment also includes a lifting device 700. The lifting device 700 and the control device are used to lift the electromagnetic device 200. The lower the pressure sensed by the pressure sensor 400, the higher the electromagnetic device 200 is raised by the control device.

[0053] During use, the pressure sensor 400 on each electromagnetic device 200 senses the pressure. When the pressure of some electromagnetic devices 200 is too low, it indicates that the human body is further away from the electromagnetic device 200. The control device then controls the lifting device 700 to raise the electromagnetic device 200 to keep the pressure sensed by each pressure sensor 400 consistent. This allows each electromagnetic device 200 to produce a uniform magnetic therapy effect on the human body, avoiding the discomfort caused by concentrated pressure and magnetic field strength. At this time, because the human body is subjected to uniform force, the user feels more comfortable.

[0054] Example 4, see Figure 8 Unlike other embodiments, the top of the lifting device 700 is fixedly connected to the front and rear swing assembly 600.

[0055] This allows for the simultaneous raising, lowering, and swinging of the electromagnetic device 200, further ensuring that the electromagnetic device 200 provides uniform magnetic therapy to the human body.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
