Description

Technical Field

[0001] The utility model relates to the technical field of magnetic fields, and particularly relates to a magnetic field generating device. Background Art

[0002] With the continuous increase of life pressure, more and more people are suffering from sleep disorders. According to a report by the World Health Organization, about 10% to 49% of the people in the world suffer from insomnia to varying degrees. Among them, the proportion of Chinese adults with varying degrees of insomnia is as high as 38.2%. How to improve sleep has become an important topic in the field of health. The doctoral dissertation of Tianjin University, "Research on Sleep Staging and Low-frequency Magnetic Field Sleep Induction", shows that through a sleep stimulation experiment on 5 healthy people with low-frequency pulsed magnetic fields (4Hz - 12Hz), the stimulation effect was analyzed by objective indicators. The results showed that the sleep latency was shortened by 9 minutes, the total sleep time was extended by 25 minutes, and the proportion of the deep sleep period was extended by 9.9%, indicating the inducing effect of low-frequency magnetic fields on sleep. Pulsed magnetic fields can promote sleep and change the sleep structure to a certain extent.

[0003] In the current technical field, a variety of magnetic therapy devices for promoting sleep have been developed. These devices can generate a static magnetic field near the user's head by using electromagnets or permanent magnets to improve sleep quality.

[0004] CN209865044U discloses a non-contact bedside magnetic therapy device for promoting sleep, which includes: a box body structure, including a magnetic therapy box with a containing cavity and arranged close to the human head, and a bushing made of flexible material arranged in the containing cavity, and the bushing is of a double-layer structure. A magnetizer is arranged in the bushing, and the magnetizer is used to generate a magnetic field that penetrates the magnetic therapy box and magnetizes the human head to improve and enhance the human sleep quality. The negative pole of the magnetizer faces the human head; an adjusting mechanism is connected to the box body structure and is used to adjust the setting position of the magnetic therapy box so that the human head is in a predetermined magnetic field. However, this patent can only use permanent magnets as the magnetic field source because if an electromagnetic method powered by a power supply is used to generate a magnetic field, when adjusting the position of the magnetizer, the position change of the magnetizer will be accompanied by the frequent movement of the power cord, which may cause the risk of the power cord being exposed and damaged. In addition, since the magnetizer is fixedly arranged on the bedside structure and is aligned with the bedside structure in the vertical direction, and there is a certain distance between the user's head and the bedside structure, it means that after the user turns over, the head is not completely within the effective magnetic field coverage area of the magnetizer.

[0005] CN219558490U discloses a spin magnetic therapy pillow, which includes a mounting pillow core and a spin magnetic generating device. An installation cavity is formed inside the mounting pillow core, and the outside is for the head and neck to rest on. The spin magnetic generating device is arranged in the installation cavity. The spin magnetic generating device includes a magnetic field generating device and a driving motor. The magnetic field generating device is used to generate a magnetic field, and the driving motor is drivingly connected to the magnetic field generating device to drive the magnetic field generating device to rotate, so as to form a rotating magnetic field that can cover the mounting pillow core, to assist sleep and improve neurasthenia. This patent ensures that the user's head can be within the magnetic field action range by setting a spin magnetic generating device in the pillow core. However, since the magnetic field generating device rotates continuously in the pillow, vibrations may be generated during its operation and transmitted to the user's head through the pillow material, which may affect the user's sleep quality. In addition, since the magnetic field generating device is built into the pillow, an external power cord needs to be set up to supply power to it. Since the power cord cannot be laid secretly, it must be exposed on the bed. Unconscious movements of the user during sleep may press the power cord, causing it to bend or break, which may lead to potential safety hazards in the long run. At the same time, since the magnetic force generator is fixedly installed inside the pillow and cannot be disassembled, this will increase the overall height of the pillow. For users who do not need to use magnetic therapy, they cannot reduce the height of the pillow by removing the magnetic force generator, thus improving the comfort and usage experience of the pillow.

[0006] In summary, a magnetic field generating device needs to be set up, which has the following characteristics: First, it can achieve a convenient power supply design without affecting the user's sleep; second, it should have the characteristic of being easy to store, so that users can store it conveniently when not in use; finally, the device has a certain ability to adjust the magnetic field action range to ensure that the magnetic field action range can partially cover the user's head even when the head position shifts after the user turns over.

[0007] In addition, on the one hand, there are differences in the understanding of those skilled in the art; on the other hand, although the applicant studied a large number of documents and patents when making this utility model, due to space limitations, all details and contents are not listed in detail. However, this does not mean that this utility model does not possess the features of these prior arts. On the contrary, this utility model already possesses all the features of the prior arts, and the applicant reserves the right to add relevant prior arts in the background art. Summary of the Utility Model

[0008] In view of the deficiencies of the prior art, this application proposes a magnetic field generating device, especially a magnetic field generating device with an adjustable magnetic field action range, aiming to solve one or more technical problems in the prior art.

[0009] In the prior art, magnetic therapy devices for promoting sleep usually generate magnetic fields by means of electromagnetic methods powered by a power supply. However, this design has significant drawbacks: the frequent movement of the power cord not only increases the risk of line exposure and damage, especially when adjusting the position of the device, but also the fixed magnetic field coverage range cannot adapt to the change in the head position caused by the user turning over, which may cause the head to move out of the effective action area of the magnetic field. The existence of these problems highlights the limitations of magnetic therapy devices in practical applications. Therefore, in order to ensure that the health benefits of magnetic therapy devices are fully realized and to maintain their operating stability, it is necessary to focus on improving the mounting structure of magnetic therapy devices to optimize their power supply mechanism and the flexibility of the magnetic field coverage range.

[0010] Therefore, in view of the above technical problems, the present utility model proposes a magnetic field generating device, which includes a magnetic generating part and an adjusting part. The magnetic generating part is connected to the adjusting part through a connecting rod. The adjusting part is configured with a clamping assembly capable of fixing the magnetic field generating device at the head of the bed. A support rod is arranged at the top of the clamping assembly. One end of the support rod away from the clamping assembly is configured with a swinging member that can rotate under the drive of a motor. The connecting rod can be detachably connected to the swinging member. The change in the magnetic field action range of the magnetic generating part on the bed body is achieved by replacing connecting rods of different lengths and / or starting and stopping the motor.

[0011] The present utility model effectively meets the storage requirements of the magnetic generating part when not in use by introducing an adjustable mechanism, and ensures a stable power supply for the magnetic generating part without affecting the user's sleep quality. In addition, the magnetic generating part is designed to have multiple specifications and can be adjusted by swinging. This feature enables the magnetic field generated by the magnetic generating part to flexibly adjust its action range even when the user's head position changes, ensuring that at least part of the head area is covered, thereby maintaining its continuous and effective magnetic field action.

[0012] According to a preferred embodiment, a magnetic box is arranged at the bottom of the connecting rod. A magnetic member for generating a magnetic field is arranged in the magnetic box. A magnetic through hole allowing magnetic induction lines to pass through is opened at the position of the magnetic box corresponding to the magnetic member. Integrating the magnetic member in the magnetic box at the bottom of the connecting rod helps to simplify the overall structure of the device, reduce the number of external components, and make the device more compact. By opening a magnetic through hole in the magnetic box, magnetic induction lines can pass through, enabling the magnetic field to be concentrated and released.

[0013] According to a preferred embodiment, one end face of the swing member is fixedly connected to the output shaft of the motor, and an insertion interface is provided on the other end face of the swing member. The insertion interface can be adapted to the insertion joint protruding from the end face of the connecting rod, so that the connecting rod is detachably connected to the swing member. By providing the mutually adapted insertion interface and insertion joint, the connecting rod can be quickly and conveniently connected or separated from the swing member. This modular design improves the flexibility and maintainability of the device. Users can replace connecting rods of different lengths or types according to needs to adapt to different usage scenarios.

[0014] According to a preferred embodiment, a wire connected to the power interface is arranged inside the connecting rod, and one end of the wire far from the power interface is electrically connected to the magnetic member. Hiding the wire inside the connecting rod not only makes the appearance of the device more tidy, but also reduces the risk of damage to the wire by the external environment, improving the safety and durability of the device.

[0015] According to a preferred embodiment, the support rod includes a cross bar and a vertical bar. Among them, the bottom end of the vertical bar can be connected to the top end of the clamping assembly, one end of the cross bar can be connected to the top end of the vertical bar, and a motor is arranged at the other end of the cross bar, and the cross bar can extend in a direction away from the head of the bed. The design of the cross bar enables it to extend in a direction away from the head of the bed. This layout provides a larger working space, enabling the device to cover a wider area and adapt to different treatment or operation requirements.

[0016] According to a preferred embodiment, a rotating member is provided at the top end of the clamping assembly. The bottom end of the vertical bar can extend into the rotating member, and the support rod can rotate around the vertical bar and rotate the magnetizing part above the head of the bed by changing the extension direction of the cross bar. The connection between the vertical bar and the clamping assembly provides a stable vertical support for the magnetizing part, ensuring the stability of the entire device during operation. This structural design helps to reduce the shaking or displacement of the device during use, improving the accuracy and safety of the operation.

[0017] According to a preferred embodiment, the clamping assembly includes two relatively arranged clamping heads. The clamping assembly can be fixed at the head of the bed by clamping the two clamping heads on two sides of the head structure respectively. The clamping assembly is fixed at the head of the bed by clamping the two clamping heads on two sides of the head structure respectively. This symmetrical design provides stable support, ensuring that the device is fixed at the head of the bed without easily moving or loosening. Since the clamping heads are relatively arranged, this design enables the clamping assembly to adapt to head structures of different widths and shapes. Users can adjust the positions of the clamping heads according to the specific size and shape of the head of the bed to achieve the best fixing effect.

[0018] According to a preferred embodiment, the clamping assembly includes a baffle disposed above the chuck. The baffle can come into contact with the top surface of the headstock structure to prevent the top surface of the headstock structure from directly abutting against the inner wall surface at the top end of the clamping assembly. The provision of the baffle allows a space for the power cord to pass through between the clamping assembly and the top surface of the headstock structure, thereby preventing the power cord from being pressed by the clamping assembly and being bent or damaged.

[0019] According to a preferred embodiment, both the cross bar and the vertical bar are configured as hollow tubes, so that the power cord connected to the motor and the power interface can pass through the tubes, and the end of the power cord away from the magnetizing part passes out from the bottom end of the rotating member.

[0020] According to a preferred embodiment, a power switch for switching the on / off state of the power cord is arranged at the top end of the clamping assembly. The power cord runs inside the hollow cross bar and vertical bar, making the appearance of the device more tidy, reducing the clutter of external cables, and improving the aesthetics of the device. Hiding the power cord can reduce the risk of the cable being accidentally pulled or tripping up the user, and reduce potential safety hazards caused by the exposed cable, such as electric shock or device damage.

Detailed implementation mode

[0030] The present utility model will be described in detail below with reference to the accompanying drawings.

[0031] The present utility model relates to a magnetic field generating device, as Figure 1 shown, the device can be placed on the bed body, preferably installed on the headboard structure, and it includes a magnet generating part 100 for generating a magnetic field and an adjusting part 200 for adjusting the position of the magnet generating part 100.

[0032] Preferably, as Figure 2 shown, the magnet generating part 100 includes a connecting rod 140 and a magnetic box 110 arranged at the bottom end of the connecting rod 140. The connecting rod 140 presents a cylindrical long rod structure, and its top end is equipped with a plug connector 160, which is matched with the socket 251 arranged in the adjusting part 200 to realize the detachable connection between the connecting rod 140 and the adjusting part 200. The magnetic box 110 is designed as a hollow box body, and a magnetic component 120 for generating a magnetic field is installed inside. The magnetic component 120 can be a permanent magnet or an electromagnet to generate a constant magnetic field. If an electromagnet is selected, a wire needs to be arranged inside the connecting rod 140, the wire penetrates through the top surface of the magnetic box 110 and is electrically connected to the electromagnet, the wire extends along the length direction of the connecting rod 140 to the end far away from the magnetic box 110, and is connected to the power supply interface 150 arranged on the wall surface of the connecting rod 140. The power supply interface 150 is connected to an external power supply through the power cord 240 in the adjusting part 200, so that the electromagnet generates a magnetic field under the drive of the power supply. If a permanent magnet is selected, the connecting rod 140 does not need to be provided with a wire and a power supply interface 150, and the magnet generating part 100 can generate a constant magnetic field without relying on an external power supply.

[0033] Preferably, as Figure 3 shown, at least one magnetic component 120 is arranged in the magnetic box 110, and a magnetic through-hole 130 allowing magnetic induction lines to pass through is opened at the position corresponding to the magnetic component 120 in the magnetic box 110, so as to optimize the distribution and intensity of the magnetic field.

[0034] Preferably, as Figure 1 、 Figure 4As shown in the figure, the adjusting part 200 is equipped with a clamping assembly 210 for firmly fixing the magnetic field generating device of the present utility model to the headboard structure of the user. The top end of the clamping assembly 210 is connected to a support rod 230, and the support rod 230 includes a vertical rod 231 and a horizontal rod 232. The vertical rod 231 is a part of the support rod 230, and its function is to be connected to the rotating part 220 at the top end of the clamping assembly 210, and its length direction is consistent with the direction of gravity. The horizontal rod 232 is another part of the support rod 230, which is connected to the top end of the vertical rod 231 and the magnetic generating part 100, and its length direction is parallel to the ground (or the bed surface). Therefore, the vertical rod 231 and the horizontal rod 232 are orthogonally arranged in structure. By extending in the direction away from the headboard structure, the horizontal rod 232 can make the magnetic generating part 100 correspond to the position of the pillow on the bed, so as to ensure that the magnetic field action range of the magnetic generating part 100 includes the user's head above the pillow.

[0035] Preferably, as Figure 1 、 Figure 4 shown, the rotating part 220 can be a ball bearing or a sliding bearing, and the vertical rod 231 connected to the rotating part 220 can rotate around its own axis. The rotation of the vertical rod 231 can change the position of the horizontal rod 232, so that it can be switched between a state perpendicular to the headboard structure and a state parallel to the headboard structure. When the user has no need to use the magnetic field generating device, the user can rotate the support rod 230 to store the magnetic generating part 100 from above the bed to above the headboard structure, reducing the occupation of the space above the bed by the magnetic generating part 100.

[0036] Preferably, as Figure 1 、 Figure 2 shown, a motor 260 and a swinging part 250 that can be driven by the motor 260 to rotate at a certain angle are arranged at one end of the horizontal rod 232 away from the vertical rod 231. The connecting rod 140 in the magnetic generating part 100 realizes the detachable connection between the magnetic generating part 100 and the horizontal rod 232 through the cooperation between the plug joint 160 at its top end and the socket 251 on the end face of the swinging part 250 facing away from the motor 260. The motor 260 has an output shaft in the same extending direction as the horizontal rod 232, and the center of one end face of the swinging part 250 is fixedly connected to the driving shaft, so that the swinging part 250 can rotate to the same extent as the rotation of the output shaft of the motor 260.

[0037] Preferably, during sleep, the user may unconsciously turn over, resulting in the head deviating from the magnetic field action range of the magnetic part 120. In this application, through the drive of the motor 260, the magnetic generating part 100 connected to the motor 260 realizes as Figure 4 and Figure 5A certain degree of swing shown in the figure. The swing of the magnet generating part 100 can synchronously change its magnetic field action range. Compared with the magnet generating part 100 with a fixed position, the magnetic field action range of the magnet generating part 100 that has experienced a swing cycle will increase significantly, which can ensure that the user's head with a position offset is at least partially within the effective magnetic field range during the swing cycle, thereby improving the utilization efficiency of the magnet generating part 100. The angle and frequency of the swing can be controlled by simply designing the operating parameters of the motor 260. In addition, the connecting rod 140 provides at least three length options (long, medium, short), and the user can select a connecting rod 140 with an appropriate length to connect to the swinging part 250 according to the height of the headboard structure. It should be clear that the present utility model does not technically improve the working principle of existing magnetic therapy products (whose core components are electromagnets or permanent magnets). The present utility model focuses on designing a kit for supporting the use of these magnetic therapy products, aiming to provide convenient storage and power supply solutions, and allowing users to adjust the magnetic field coverage position of the magnetic therapy products according to personal needs to meet specific treatment or comfort requirements.

[0038] Preferably, as Figure 6 , Figure 7 shown, both the cross bar 232 and the vertical bar 231 are configured as hollow tubes, so that the power cord 240 connected to the motor 260 and the power supply interface 150 can pass through the tube body, and the end of the power cord 240 far from the magnet generating part 100 can pass out from the bottom end of the rotating part 220 and be connected to an external power supply. The top of the clamping assembly 210 is configured with a power switch 270 for switching the on / off state of the power cord 240. The number of power switches 270 can be set to one to simultaneously control the on / off of the power cord 240 connected to the motor 260 and the power cord 240 connected to the magnetic part 120; the number of power switches 270 can also be set to two to separately control the on / off of the power cord 240 connected to the motor 260 and the power cord 240 connected to the magnetic part 120.

[0039] Preferably, as Figure 4 , Figure 7 shown, the clamping assembly 210 includes two relatively arranged chucks 211, and the two chucks 211 can be respectively clamped on two sides of the headboard structure to fix the entire clamping assembly 210 at the headboard position. In particular, the clamping assembly 210 further includes a baffle 212 arranged above the chuck 211, and the baffle 212 can contact the top surface of the headboard structure. The setting of the baffle 212 enables a space for the power cord 240 to pass through to be reserved between the clamping assembly 210 and the top surface of the headboard structure, thereby preventing the power cord 240 from being bent or damaged due to being pressed by the clamping assembly 210.
