Description

Technical Field

[0001] This application belongs to the field of magnetic therapy device technology, and in particular relates to a magnetic therapy massage device for the waist and its adjustment method. Background Technology

[0002] Commonly available magnetic massage devices for the lower back can be categorized into automatic and passive types based on their level of automation. The former typically includes a motor and / or cylinder, requiring electricity to operate. The latter, however, has a simpler structure; the user moves and bends their lower back to achieve basic magnetic therapy with a dynamic massage effect.

[0003] The core structure of the aforementioned device consists of magnetic particles, which are typically made of artificial permanent magnets. When these magnetic particles are placed firmly and appropriately against the user's lower back, the magnetic therapy massage function becomes effective.

[0004] For example, Chinese utility model patent with authorization announcement number CN215938237U and authorization announcement date of 2022.03.04 discloses a spinal stretching magnetic therapy massager, whose main structural components include: supporting side plate, elastic feet, massage roller, arc-shaped groove, magnet, and hot stone column.

[0005] The advantages and functions of the magnetic therapy massager in this utility model patent are as follows: the massage roller is rotatably connected to the supporting side plate and comes into contact with the spine on the back of the human body, so that the massage roller can effectively fit the above-mentioned parts and improve the comfort of the spinal stretching magnetic therapy massage function.

[0006] However, in actual use, this magnetic massager still has at least the following practical problems, specifically:

[0007] First, its magnetic structure is fixed to and exposed with the massage roller, and is used to directly press against the user's waist. Therefore, the magnet is relatively easy to be bumped and broken, and the replacement operation is relatively troublesome after it is broken.

[0008] Secondly, the dynamic effect of its magnetic structure is mainly based on the rotation around the massage roller, corresponding to the waist stretching action. However, the more common and simple left and right twisting of the waist is difficult to drive the magnet to rotate, and thus can only achieve a relatively sliding massage effect, which is equivalent to the magnet sliding left and right at the waist position. This will generate greater frictional resistance, making the massage method more painful and impractical. Summary of the Invention

[0009] This application provides a magnetic therapy massage device for the waist, and the technical problem to be solved is: how to make an active magnetic therapy massage device for the waist have the dual advantages of magnetic particles that are not easily bumped and are easy to replace, and a more comprehensive active triggering magnetic particle rolling massage mode.

[0010] In addition, this application also provides a method for adjusting the above-mentioned magnetic massage device for the waist.

[0011] The technical solution adopted by this application to solve the above problems is: a magnetic massage device for the waist, the structure of which includes magnetic particles, a grooved base plate unit, a massage ball disposed on the grooved base plate unit and having the magnetic particles inside, which is used to press against the user's waist, and a detachable elastic perforated plate unit disposed on the upper surface of the grooved base plate unit, exposing the massage ball, which is used to support the user's waist.

[0012] A further preferred technical solution is that the grooved bottom plate unit includes a bottom support plate and a circular groove disposed on the upper surface of the bottom support plate for mounting the massage ball.

[0013] A further preferred technical solution is that the detachable elastic perforated plate unit includes a top elastic plate disposed on the upper surface of the bottom support plate and used to support the user's waist, and a circular opening disposed on the top elastic plate and used to expose the massage ball.

[0014] A further preferred technical solution is that: the grooved bottom plate unit further includes a permanent magnet sheet disposed on the bottom support plate and located below the circular groove; the massage ball is also provided with an internal spherical cavity for installing the magnetic particles, and the permanent magnet sheet and the magnetic particles are magnetically attracted and parallel.

[0015] A further preferred technical solution is that the grooved bottom plate unit further includes a circular protective plate disposed on the upper surface of the permanent magnet sheet and used to support the massage ball, and an integral support plate disposed on the lower surface of the permanent magnet sheet.

[0016] A further preferred technical solution is that the grooved bottom plate unit also includes a circular integral hole disposed on the circular protective plate and the permanent magnet sheet, which increases the installation height of the overall support plate by engaging the massage ball, thereby increasing the thickness of the bottom support plate in the area below the overall support plate.

[0017] A further preferred technical solution is that the massage ball comprises a rigid hemisphere and an elastic hemisphere that are bonded or welded together;

[0018] When the rigid or elastic hemisphere is supported alone on the edge of the integral hole, the massage ball provides an elastic or rigid massage tip accordingly.

[0019] When the rigid hemisphere and the elastic hemisphere are supported together on the edge of the integral hole, the massage ball provides an eccentric massage tip.

[0020] A further preferred technical solution is that: the internal spherical cavity is also provided with lubricating oil for maintaining the parallel state between the permanent magnet sheet and the magnetic particles.

[0021] A further preferred technical solution is that the detachable elastic perforated plate unit further includes a circular hole limiting plate disposed on the lower surface of the top elastic plate and used to block the massage ball.

[0022] A method for adjusting a magnetic massage device for the waist includes the following steps:

[0023] S1. Remove the detachable flexible perforated plate unit from the grooved base plate unit;

[0024] S2. Replace with massage balls of different diameters;

[0025] S3. Reinstall the detachable elastic perforated plate unit on the grooved base plate unit, so that the detachable elastic perforated plate unit still blocks and limits the massage ball, and finally adjusts the massage intensity of the magnetic therapy massage device, or the massage intensity and magnetic therapy intensity.

[0026] The beneficial effects of this application include at least the following six points.

[0027] First, this magnetic massage device for the waist requires active activation by the user. During this process, the user's waist movements, whether up and down or left and right, can drive the massage ball to rotate, which in turn drives the magnetic particles inside. Therefore, this device combines the advantages of safe and durable magnetic particles with a more comprehensive active massage method.

[0028] Secondly, in this device, the massage ball is hollow and the magnetic particles are fixed by a permanent magnet, so that when the massage ball rotates, the magnetic particles do not follow it and are always parallel to the user's waist, thus making the magnetic poles face the waist and ultimately enhancing the intensity of the magnetic therapy function.

[0029] Third, in this device, the circular protective plate, permanent magnet sheet, and overall support plate are arranged as a single unit from top to bottom. This allows the rotating function of the massage ball to have the dual advantages of being less prone to sinking and less likely to crush the permanent magnet sheet. If the massage ball sinks significantly, its strength against the user's waist will decrease, ultimately leading to a reduction in massage intensity, which needs to be avoided.

[0030] Fourth, in this device, the massage spheres include hard hemispheres and elastic hemispheres, and are used in conjunction with the edge of the integral hole. This allows the sphere massage function to not only provide elastic or hard massage heads respectively, but also to provide eccentric massage heads, making the massage function more diverse and significantly improving the practicality of the device's massage function.

[0031] Fifth, in this device, the lubricating oil can significantly reduce the frictional resistance between the magnetic particles and the internal spherical cavity, making it easier for the magnetic particles to maintain a horizontal state, thereby ensuring that the magnetic therapy effect is always at its strongest.

[0032] Sixth, the above adjustment method is simple and convenient. It can adjust the massage intensity alone or the massage intensity and magnetic therapy intensity at the same time, thus further improving the practicality and flexibility of the device. Attached Figure Description

[0051] The following description is merely a preferred embodiment of this application and is not intended to limit the scope of this application.

[0052] As attached Figure 1 -Appendix Figure 11 As shown, a magnetic massage device for the waist includes magnetic particles 11, a grooved base plate unit 1, a massage ball 2 disposed on the grooved base plate unit 1 and having the magnetic particles 11 inside, which is used to press against the user's waist, and a detachable elastic perforated plate unit 3 disposed on the upper surface of the grooved base plate unit 1, exposing the massage ball 2, which is used to support the user's waist.

[0053] In this embodiment, the specific structure of the device includes, for example, 12 magnetic particles 11, 1 grooved base plate unit 1, 12 massage balls 2, 1 detachable elastic perforated plate unit 3, and 2 Velcro straps 6.

[0054] Among them, the magnetic particles 11 are artificial permanent magnets and are circular in shape; the main body material of the grooved bottom plate unit 1 is hard plastic and is rectangular in shape; the main body material of the massage ball 2 is relatively hard rubber; and the main body material of the detachable elastic perforated plate unit 3 is foamed sponge and is also rectangular in shape.

[0055] When in use, the long side of the device is perpendicular to the length of the spine. There are 6 massage balls 2 on each side of the spine. The user's waist can rotate by moving up and down or twisting left and right, which in turn drives the magnetic particles 11 inside, thereby realizing the combined function of magnetic therapy and massage. Moreover, the friction between the massage balls 2 and the user's waist is rolling friction, which is less than sliding friction, so the massage comfort is relatively high.

[0056] On the other hand, when the device is in use, the deformation of the grooved base plate unit 1 under pressure is relatively small and negligible compared to the detachable elastic perforated plate unit 3. When the device is not in use, it is not necessary for the upper end of the massage ball 2 to protrude beyond the upper surface of the detachable elastic perforated plate unit 3, as long as it ensures that when the user's waist is pressed against the detachable elastic perforated plate unit 3, the massage ball 2 can adequately and appropriately support the waist.

[0057] The grooved bottom plate unit 1 includes a bottom support plate 101 and a circular groove 102 disposed on the upper surface of the bottom support plate 101 for mounting the massage ball 2.

[0058] In this embodiment, the thickness of the bottom support plate 101 is 3-8cm, the diameter of the circular groove 102 is 1-2cm larger than the diameter of the massage ball 2, and its depth is greater than the radius of the massage ball 2, so that the massage ball 2 can rotate in any direction within the circular groove 102 without significant lateral displacement.

[0059] The detachable elastic perforated plate unit 3 includes a top elastic plate 301 disposed on the upper surface of the bottom support plate 101 and used to support the user's waist, and a circular opening 302 disposed on the top elastic plate 301 and used to expose the massage ball 2.

[0060] In this embodiment, the thickness of the top elastic plate 301 in the uncompressed state is 5-10cm, and the hook side of the nylon hook and loop fastener 6 is sewn or glued to its lower surface. The velvet side of the nylon hook and loop fastener 6 is sewn or glued to the upper surface of the bottom support plate 101.

[0061] Furthermore, the position and number of the circular openings 302 correspond to the circular grooves 102, and their diameter can be less than, equal to or greater than the diameter of the massage ball 2, ensuring that the upper end of the massage ball 2 can directly press against the user's waist.

[0062] The grooved bottom plate unit 1 also includes a permanent magnet sheet 103 disposed on the bottom support plate 101 and located below the circular groove 102; the massage ball 2 is also provided with an internal spherical cavity 4 for installing the magnetic particles 11, and the permanent magnet sheet 103 and the magnetic particles 11 are magnetically attracted and parallel.

[0063] In this embodiment, as shown in the appendix Figure 3 As shown, the first installation method of the magnetic particles 11 is as follows: during the manufacturing of the massage ball 2, the magnetic particles 11 are directly wrapped inside, and the relative positions of the two are fixed. The main advantage of this method is that the manufacturing method is relatively simple. The main disadvantage is that during the rotation of the massage ball 2 along with the magnetic particles 11, the magnetic particles 11 will not be parallel to the waist for most of the time. That is, the magnetic poles cannot be directly aligned with the waist, and the area with the densest magnetic field lines cannot provide a direct magnetic therapy effect, thus greatly reducing the intensity of magnetic therapy.

[0064] And as attached Figure 5 As shown, the second installation method of the magnetic particles 11 is as follows: the massage ball 2 is hollow, and its advantages and disadvantages are exactly the opposite of the first installation method. Therefore, the second installation method can be considered the preferred solution.

[0065] When the device is in use, the position of the magnetic particles 11 remains largely unchanged, and they slide and rub against the inner spherical cavity 4, i.e., the inner spherical surface of the massage ball 2. The magnetic poles of the magnetic particles 11 are always facing the user's waist, so the magnetic therapy intensity is relatively high.

[0066] The grooved bottom plate unit 1 further includes a circular protective plate 104 disposed on the upper surface of the permanent magnet sheet 103 and used to support the massage ball 2, and an integral support plate 105 disposed on the lower surface of the permanent magnet sheet 103.

[0067] In this embodiment, during the manufacturing of the grooved bottom plate unit 1, the entire structure with the circular protective plate 104 on top, the permanent magnet sheet 103 in the center, and the overall support plate 105 at the bottom is first connected together by bonding or welding. Then, the entire grooved bottom plate unit 1 is formed on this integral structure.

[0068] The circular protective plate 104 and the overall support plate 105 can be made of either metal or hard plastic. Their main functions are similar: the circular protective plate 104 prevents the massage ball 2 from directly pressing against the permanent magnet sheet 103, otherwise the relatively fragile permanent magnet sheet 103 will break due to excessive pressure. The direct function of the circular protective plate 104 is to increase the pressure-bearing area.

[0069] Correspondingly, the overall support plate 105 is used to prevent the permanent magnet sheet 103 from directly pressing the bottom support plate 101 area below it. Otherwise, the hard plastic material in this area is also prone to collapse and crack due to excessive pressure. The direct function of the overall support plate 105 is to increase the pressure-bearing area.

[0070] Specifically, the number of circular protective plates 104 is the same as that of permanent magnet pieces 103, but the overall support plate 105 is only one whole plate with a rectangular shape, which further increases the pressure-bearing area. This is also the meaning of the word "whole" in the overall support plate 105.

[0071] The grooved bottom plate unit 1 also includes a circular integral hole 106 disposed on the circular protective plate 104 and the permanent magnet sheet 103, which increases the installation height of the overall support plate 105 by engaging the massage ball 2, thereby increasing the thickness of the bottom support plate 101 in the area below the overall support plate 105.

[0072] In this embodiment, the forming method of the circular integral hole 106 can be, for example, that the circular protective plate 104 is a ring-shaped plate and the permanent magnet sheet 103 is a ring-shaped magnet. For details, please refer to the attached document. Figure 6 .

[0073] The term "integral" in "integral circular hole 106" refers to the fact that both the circular protective plate 104 and the permanent magnet sheet 103 have circular holes, so that the bottom of the massage ball 2 can enter the integral circular hole 106 relatively large.

[0074] Accordingly, the first main function of the circular integral hole 106 is:

[0075] Under the premise that the thickness of the bottom support plate 101 remains unchanged and the massage ball 2 can still be stably supported, the height of the overall structure of the circular protective plate 104, permanent magnet sheet 103 and overall support plate 105 can be appropriately raised, so that the material thickness in the area below the overall support plate 105 increases, making it more difficult for the overall support plate 105 to deform or crack this area, and ultimately extending the effective service life of the device.

[0076] Specifically, the bottom height of the circular groove 102 can be located within the area of ​​the upper surface of the circular protective plate 104 and the upper surface of the overall support plate 105.

[0077] The massage ball 2 includes a rigid hemisphere 201 and an elastic hemisphere 202 that are bonded or welded together.

[0078] When the rigid hemisphere 201 or the elastic hemisphere 202 is supported alone on the edge of the integral hole 106-1, the massage ball 2 is provided with an elastic or rigid massage tip accordingly.

[0079] When the rigid hemisphere 201 and the elastic hemisphere 202 are supported together on the integral hole edge 106-1, the massage ball 2 provides an eccentric massage end.

[0080] In this embodiment, the main functions of the combined use of the rigid hemisphere 201 and the elastic hemisphere 202 include the following two:

[0081] First, the operation of inserting the magnetic particles 11 into the massage ball 2 is relatively simple and convenient. The hard hemisphere 201 and the elastic hemisphere 202 can be welded or bonded together to effectively install the magnetic particles 11.

[0082] Second, the massage ball 2 is allowed to provide two different elastic hemispheres with completely different tactile sensations, namely, as shown in the attached figure. Figure 8 As shown, when the elastic hemisphere 202 is on top, its upper end is deformed under pressure, corresponding to the aforementioned deformation amount, and can also be described as follows: Figure 9 As shown, the rigid hemisphere 201 is on top, and its deformation is negligible. However, the elastic hemisphere 202 below is compressed, causing the rigid hemisphere 201 to move downward as a whole. Corresponding to the aforementioned deformation, the sphere rolling massage method becomes more diversified, improving the practicality of the device.

[0083] In addition, the following two points need to be specifically noted:

[0084] Firstly, the rigid hemisphere 201 is made of metal or rigid plastic, while the elastic hemisphere 202 is made of common elastic rubber, which has greater elasticity than the top elastic plate 301.

[0085] Secondly, the second function mentioned above applies to the circular protective plate 104 regardless of whether the circular integral hole 106 is opened.

[0086] On the other hand, the second main function of the circular integral hole 106 is that it needs to be used in conjunction with the rigid hemisphere 201 and the elastic hemisphere 202, as follows:

[0087] As attached Figure 10As shown, the rigid hemisphere 201 and the elastic hemisphere 202 are supported together on the edge of the integral hole 106-1. Due to the difference in hardness between the two, the entire massage ball 2 will shift and move to the above-mentioned eccentric position a, so that the massage ball 2, which could only roll in place, also has a slight shifting effect, further enhancing the diversity of rolling massage methods.

[0088] Accordingly, the following two points also need to be explained:

[0089] First, the above-mentioned eccentricity of the massage ball 2 refers to the fact that its center does not coincide with the central axis of the integral hole edge 106-1. This eccentricity is relatively small, occurs repeatedly and disappears quickly, so it does not affect the parallel use effect of the magnetic particles 11.

[0090] Secondly, the specific position and effective length of the elastic hemisphere 202 pressed on the edge 106-1 of the overall hole are uncertain, which makes the above-mentioned eccentricity phenomenon more variable and diverse, and ultimately makes the rolling massage method more delicate and practical.

[0091] The internal spherical cavity 4 is also provided with lubricating oil 5 to maintain the parallel state of the permanent magnet sheet 103 and the magnetic particles 11.

[0092] In this embodiment, the lubricating oil 5 is a commercially available product, which is installed together with the magnetic particles 11 into the internal spherical cavity 4. The main function of the lubricating oil 5 is to further reduce the sliding friction intensity between the lower edge of the magnetic particles 11 and the internal spherical cavity 4, thereby slowing down the wear of both the magnetic particles 11 and the inner spherical surface of the massage ball 2.

[0093] Furthermore, as shown in the attached document. Figure 11 As shown, the magnetic particle 11 has at least one rounded chamfer edge. By selecting the orientation of the magnetic poles of the permanent magnet sheet 103, the chamfered position is the only position where the magnetic particle 11 directly contacts the internal spherical cavity 4. This can further reduce the wear rate of the magnetic particle 11 and the inner spherical surface of the massage ball 2, which further improves the practicality of the device.

[0094] The detachable elastic perforated plate unit 3 also includes a circular hole limiting plate 303 disposed on the lower surface of the top elastic plate 301 and used to block the massage ball 2.

[0095] In this embodiment, the position and number of the circular holes on the circular hole limiting plate 303 are consistent with those of the circular groove 102. However, the diameter of the circular holes is smaller than that of the circular groove 102, and also smaller than the diameter or outer diameter of the massage ball 2. This makes it less likely for the massage ball 2 to fall out or be lost even if the device is stored upside down or without the permanent magnet 103.

[0096] On the other hand, the diameter of the circular opening 302 is greater than or equal to the diameter of the circular hole in the circular hole limiting plate 303.

[0097] A method for adjusting a magnetic massage device for the waist includes the following steps:

[0098] S1. Remove the detachable elastic perforated plate unit 3 from the grooved bottom plate unit 1;

[0099] S2. Replace with massage balls of different diameters;

[0100] S3. Reinstall the detachable elastic perforated plate unit 3 on the grooved bottom plate unit 1, so that the detachable elastic perforated plate unit 3 still blocks and limits the massage ball 2, and finally adjusts the massage intensity of the magnetic therapy massage device, or the massage intensity and magnetic therapy intensity.

[0101] In this embodiment, the massage ball 2 and the magnetic particles 11 therein are considered as a whole structure and are used interchangeably.

[0102] The 12 massage balls 2 mentioned above may differ in diameter / outer diameter, material, and magnetic field strength of their internal magnetic particles. That is, massage balls 2 of different specifications and types can be used interchangeably to ensure that the above-mentioned various rolling massage functions are effective or partially effective.

[0103] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various modifications can be made without departing from the spirit of this application. These are non-inventive modifications and are protected by patent law as long as they are within the scope of the claims of this application.
