Description

Technical Field

[0001] This invention relates to the field of smart bed technology, and in particular to a smart bed. Background Technology

[0002] Smart furniture is based on modern and stylish furniture, cleverly integrating combined intelligence, electronic intelligence, mechanical intelligence, and Internet of Things intelligence into furniture products, making furniture intelligent, international, and fashionable, and making home life more convenient and comfortable.

[0003] In existing technologies, smart beds include a bed frame, mattress, and pillow. The pillow can be height-adjustable, allowing it to adjust its height for different users and sleeping positions to achieve optimal comfort and play a positive role in preventing cervical spondylosis. However, it cannot treat or alleviate cervical spondylosis. The pillow can also be configured as a "health pillow," which, by designing the top surface of the pillow core with a camel-hump shape and a tongue-like feature, perfectly conforms to the head and neck, providing continuous traction to the cervical spine and potentially treating and alleviating cervical spondylosis to some extent. However, because this type of health pillow is fixed, its traction effect on the cervical spine is less effective. The mattress can be configured as a mattress with a vibrating massager, which includes a mattress body made of a flexible and elastic material. The lower surface of the mattress body has a groove for embedding the vibration module. The groove opening is provided with a matching insert pad. The vibration module is clamped and positioned in the cavity formed by the groove and the insert pad. However, because the mattress body is elastic, the vibration module is prone to displacement in the mattress body, which affects the massage experience. In addition, the vibration module in the existing technology usually uses a brushed motor, which has a short service life, thus increasing maintenance costs. Therefore, how to design a smart bed to improve the user experience is a key research direction in the industry.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of the above, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide an intelligent bed, which is equipped with a back support frame and a first lifting mechanism. The first lifting mechanism can drive the back support frame to rotate relative to the main frame, allowing the human body to be in a more comfortable lying position. Furthermore, the control system has a cervical spine reverse traction mode. The pillow drive mechanism drives the cervical support part to swing up and down through a swinging component. In the cervical spine reverse traction mode, the first lifting mechanism and the pillow drive mechanism simultaneously perform reciprocating motion, enabling the cervical support part to perform reverse traction correction on the human neck, thereby effectively treating and relieving cervical spondylosis. Additionally, the straps are detachable, facilitating strap assembly and preventing the human head from leaving the head support area during the cervical spine reverse traction mode, ensuring that the human neck remains close to the cervical support area and improving the massage effect of cervical spine reverse traction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A smart bed includes a bed frame, a mattress, a pillow, a pillow drive mechanism, and a control system. The bed frame includes a main frame and a support frame assembly disposed on the top of the main frame. The mattress is disposed on the support frame assembly. The support frame assembly includes a back support frame that is rotatable relative to the main frame. A first lifting mechanism for driving the back support frame to rotate relative to the main frame is connected between the bottom of the back support frame and the main frame. The first lifting mechanism is electrically connected to the control system. The first lifting mechanism can drive the back support frame to rotate relative to the main frame, allowing the human body to be in a more comfortable lying position.

[0008] The pillow has a head support area and a neck support area at the top, with the neck support area being higher than the head support area. The pillow has a frame inside, and the frame has a neck support part corresponding to the neck support area for traction against the arch of the human neck. The bottom of the frame is exposed at the bottom of the pillow.

[0009] The pillow drive mechanism is electrically connected to the control system. The pillow drive mechanism is set on the back support frame. The pillow drive mechanism includes a mounting base, a rotary drive device set on the mounting base, and a rotating shaft rotatably connected to the mounting base. The rotating shaft is sleeved with an eccentrically set swing member. The top of the swing member is connected to the bottom of the frame.

[0010] The pillow is detachably connected to a strap for fixing the human head in the head support area. The control system has a cervical spine reverse traction mode. In the cervical spine reverse traction mode, the first lifting mechanism and the pillow driving mechanism reciprocate simultaneously to achieve reverse traction correction of the human neck by the cervical support part, so as to better treat and relieve cervical spondylosis. In addition, the strap is detachable, which facilitates the assembly of the strap and prevents the human head from leaving the head support area in the cervical spine reverse traction mode, ensuring that the human neck is in close contact with the cervical support area and improving the massage effect of cervical spine reverse traction.

[0011] As a preferred embodiment, the pillow has a receiving groove for accommodating the frame. The pillow is fitted over the frame through the receiving groove. The frame includes a head support and a positioning member connected to the head support for connecting with the swinging member. The neck support extends obliquely upward from the head support. The frame is connected to the swinging member through the positioning member.

[0013] As a preferred embodiment, the transmission assembly includes a turntable, a spherical bearing, and a connecting rod. The turntable is connected to a rotary drive device, and a connecting portion is eccentrically provided on the turntable. One end of the spherical bearing is hinged to the connecting portion, and the other end of the spherical bearing is hinged to one end of the connecting rod. The other end of the connecting rod is connected to a rotating shaft, and a slot is provided at the other end of the connecting rod. Correspondingly, a locking position matching the slot is provided on the rotating shaft, and the slot is engaged with the locking position. Alternatively, the other end of the connecting rod is fixed to the rotating shaft by screws.

[0014] As a preferred embodiment, the rotary drive device includes a stepper motor and a second synchronous belt pulley reduction assembly connected to the stepper motor. The stepper motor is equipped with a silent drive chip, and the output end of the second synchronous belt pulley reduction assembly is connected to a transmission assembly.

[0015] As a preferred embodiment, the mattress contains a vibrator connected to a control system. The vibrator includes a vibrating plate, a mounting bracket mounted on the vibrating plate, and a vibrating motor mounted on the mounting bracket; wherein:

[0016] The vibrating plate is provided with a plurality of first bolts, the mounting bracket passes through the first bolts and abuts against the vibrating plate, the first bolts are connected with a first nut for fixing the mounting bracket to the vibrating plate, the mounting bracket is provided with a foldable limiting part on the side of the first nut for preventing the first nut from loosening, and the rotation of the first nut is restricted by the foldable limiting part;

[0017] The vibrating plate is provided with a cover, the mounting bracket is located inside the cover, and the cover has an installation opening on the side facing the mounting bracket. The mounting bracket is installed inside the cover through the installation opening.

[0018] As a preferred embodiment, the mounting bracket includes a horizontal plate and a vertical plate connected to the horizontal plate. The vibration motor is arranged horizontally and mounted on the vertical plate. One end of the vibration motor near the vertical plate is fixedly connected to the vertical plate. A second bolt is provided on the vibration plate, and a fixing sleeve passes through the second bolt. The second bolt is connected to a second nut for fixing the fixing sleeve to the horizontal plate. The fixing sleeve is located at the other end of the vibration motor away from the vertical plate.

[0019] As a preferred embodiment, a rubber ring is fitted on the end of the vibration motor away from the vertical plate, and the fixing sleeve presses against the rubber ring.

[0020] As a preferred embodiment, the vibration motor is a brushless motor, and the vibration motor is connected to an oscillator.

[0021] As a preferred embodiment, the mattress includes a mattress body and a mattress cover fitted over the mattress body. The mattress body includes, from bottom to top, a first PK cotton layer, an elastic layer, a second PK cotton layer, a 3D cotton layer, and a memory foam layer. The vibration plate is sandwiched between the elastic layer and the second PK cotton layer. The elastic layer has a clearance groove for the cover to avoid. The first PK cotton layer covers the clearance groove. A PK cotton body is also sandwiched between the cover and the first PK cotton layer.

[0022] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0023] Its main features include a back support frame and a first lifting mechanism. The first lifting mechanism can rotate the back support frame relative to the main frame, allowing the body to be in a more comfortable lying position. The control system also features a cervical spine reverse traction mode. The pillow drive mechanism drives the cervical support to swing up and down via a swinging component. In the cervical spine reverse traction mode, the first lifting mechanism and the pillow drive mechanism simultaneously reciprocate, enabling the cervical support to perform reverse traction correction on the neck, thus effectively treating and relieving cervical spondylosis. Furthermore, the strap is detachable, facilitating its assembly and preventing the head from leaving the head support area during the cervical spine reverse traction mode, ensuring the neck remains close to the support area and enhancing the massage effect of the cervical spine reverse traction.

[0024] Secondly, by incorporating a vibrating plate, the vibration of the vibrating motor is transmitted through the vibrating plate, resulting in better transmission. When the vibrating plate is placed on the mattress, it is less likely to shift. Furthermore, the vibrating motor is mounted on a mounting frame, which is installed on the vibrating plate using bolts and nuts, making it easy to disassemble, maintain, and replace. Additionally, the mounting frame is equipped with a foldable limiting part. After the nuts are secured, the foldable limiting part can be folded to the side of the first nut, thereby preventing the mounting frame from loosening from the vibrating plate and ensuring good stability.

[0025] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0076] First, it should be noted that in the description of this invention, the terms "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0077] Please refer to Figures 1 to 12 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a bed frame 40, a pillow 10, a pillow drive mechanism 20, a mattress 50, and a control system 70.

[0078] See Figure 2 As shown, the bed frame 40 includes a main frame 41, floor feet 42 disposed at the bottom of the main frame 41, and a support frame assembly 43 disposed at the top of the main frame 41. The support frame assembly 43 includes a back support frame 431 that can be rotatably disposed relative to the main frame 41. A first lifting mechanism 44 for driving the back support frame 431 to rotate relative to the main frame 41 is connected between the bottom of the back support frame 431 and the main frame 41. The first lifting mechanism 44 is electrically connected to the control system 70. The first lifting mechanism 44 can drive the back support frame 431 to rotate relative to the main frame 41, so that the human body can be in a more comfortable lying position. The first lifting mechanism 44 can be an electric cylinder.

[0079] Specifically, the support frame assembly 43 further includes a fixed support frame 432, a thigh support frame 433, and a calf support frame 434. The back support frame 431, the fixed support frame 432, the thigh support frame 433, and the calf support frame 434 are arranged side by side with a spacing and hinged sequentially. A first lifting mechanism 44 for driving the back support frame 431 to rotate relative to the fixed support frame 432 is connected between the bottom of the back support frame 431 and the main frame 41. A second lifting mechanism (not shown in the figure) for driving the thigh support frame 433 to rotate relative to the fixed support frame 432 is connected between the bottom of the thigh support frame 433 and the main frame 41. A linkage rod (not shown in the figure) is connected between the calf support frame 434 and the main frame 41, and the thigh support frame 433 moves in conjunction with the calf support frame 434.

[0080] The top of the pillow 10 has a head support area 101 and a neck support area 102, with the neck support area 102 being higher than the head support area 101; the pillow 10 is provided with a frame 11, and the frame 11 is provided with a neck support part 111 for traction of the human neck in the neck support area 102, with the bottom of the frame 11 protruding from the bottom of the pillow 10.

[0081] See Figure 5 and Figure 6 As shown, specifically, the pillow 10 has a receiving groove 103 for accommodating the frame 11. The pillow 10 is fitted onto the frame 11 through the receiving groove 103. The frame 11 includes a head support part 112 and a positioning part 113 connected to the head support part 112 for connecting with the swinging member 24. The neck support part 111 extends obliquely upward from the head support part 112. In this embodiment, the frame 11 is made of wood. During processing, a cavity 104 is opened downward at the top of the frame 11 to form the head support part 112 and the neck support part 111. The neck support part 111 has an arc-shaped surface 114.

[0082] See Figure 6As shown, the bottom of the positioning member 113 is provided with a positioning post 115. Preferably, the frame 11 is also provided with a magnetic suction member 116 for adsorbing and fixing with the swing member 24. In this embodiment, the positioning member 113 is a metal sheet. The positioning member 113 is fixed to the top of the head support 112. The positioning post 115 is provided at the bottom of the positioning member 113 and protrudes from the bottom of the frame 11. The bottom of the frame 11 is provided with an upwardly recessed mounting groove 105 on the side of the positioning post 115. The magnetic suction member 116 is fixed in the mounting groove 105 by screws. The bottom of the mounting groove 105 is provided with a cover plate 117 for covering the mounting groove 105. The positioning post 115 is two positioned at a distance. The magnetic suction member 116 is a magnet and is provided between the two positioning posts 115.

[0083] The pillow drive mechanism 20 is located on the top of the back support frame 431. The pillow drive mechanism 20 includes a mounting base 21, a rotary drive device 22 located on the mounting base 21, and a rotating shaft 23 rotatably connected to the mounting base 21. The rotating shaft 23 is sleeved with an eccentrically arranged swing member 24. The top of the swing member 24 is connected to the bottom of the frame 11. The rotary drive device 22 drives the rotating shaft 23 to rotate back and forth at a certain angle through the transmission component 30, and then drives the neck support part 111 to swing up and down through the swing member 24, thereby realizing the reciprocating reverse arch traction of the human neck, so as to better treat and relieve cervical spondylosis.

[0084] See Figure 6 As shown, specifically, the frame 11 is connected to the swing member 24 via a positioning member 113. The swing member 24 has a positioning hole 241 for the positioning post 115 to be inserted. The positioning post 115 is inserted into the positioning hole 241. The positioning post 115 and the positioning hole 241 facilitate the assembly of the pillow 10 onto the pillow drive mechanism 20. The frame 11 is magnetically connected to the swing member 24 via a magnetic suction member 116. The magnetic suction member 116 can better prevent the pillow 10 from detaching from the pillow drive mechanism 20. Furthermore, the top of the swing member 24 is an abutting plane 242, which abuts against the bottom of the frame 11.

[0085] See Figure 3As shown, the pillow 10 is detachably connected to a strap 12 for fixing the human head in the head support area. The control system 70 has a cervical spine reverse traction mode. In the cervical spine reverse traction mode, the first lifting mechanism and the pillow driving mechanism reciprocate simultaneously to achieve reverse traction correction of the human neck by the cervical support part, so as to better treat and relieve cervical spondylosis. In addition, the strap 12 is detachable, which facilitates the assembly of the strap 12. At the same time, it can prevent the human head from leaving the head support area in the cervical spine reverse traction mode, ensuring that the human neck is close to the cervical support area and improving the massage effect of cervical spine reverse traction. Specifically, the two ends of the strap 12 are magnetically attached to the pillow 10.

[0086] See Figure 5 As shown, the transmission assembly 30 includes a turntable 31, a spherical bearing 32, and a connecting rod 33. The turntable 31 is connected to the rotary drive device 22. A connecting part 311 is eccentrically provided on the turntable 31. One end of the spherical bearing 32 is hinged to the connecting part 311, and the other end of the spherical bearing 32 is hinged to one end of the connecting rod 33. The other end of the connecting rod 33 is connected to the rotating shaft 23.

[0087] Specifically, the other end of the connecting rod 33 is provided with a slot 331, and correspondingly, the rotating shaft 23 is provided with a snap-fit ​​position (not shown in the figure) that matches the slot 331. The slot 331 is snapped into the snap-fit ​​position. The slot 331 and the snap-fit ​​position can prevent the rotating shaft 23 and the connecting rod 33 from rotating relative to each other; or, the other end of the connecting rod 33 is fixed to the rotating shaft 23 by screws.

[0088] Preferably, the two swing members 24 are arranged at a distance, and the arrangement of two swing members 24 can support the pillow 10 more stably.

[0089] See Figure 5 As shown, the rotary drive device 22 includes a stepper motor 221 and a second synchronous belt pulley reduction assembly 222 connected to the stepper motor 221. The stepper motor 221 is equipped with a silent drive chip. The output end of the second synchronous belt pulley reduction assembly 222 is connected to the transmission assembly 30. The configuration of the silent drive chip in the stepper motor 221 results in lower noise during operation of the rotary drive device 22, thereby reducing the impact on sleep. The stepper motor 221 can be a 4260 model, and the silent drive chip is a TMC2240 model. In actual use, a soundproof cover 60 is installed outside the pillow drive mechanism 20 to further reduce the noise generated by the pillow drive mechanism 20 during operation.

[0090] Specifically, the second synchronous belt pulley reduction assembly 222 includes a set of second synchronous belt pulley reduction groups. The second synchronous belt pulley reduction group is an existing mature technology and will not be described in detail here. Its reduction ratio can be 1:6. Since the stepper motor 221 has a large torque, only one set of second synchronous belt pulley reduction groups is needed. The stepper motor 221 can make the connecting rod 33 run smoothly when lifting and lowering. The stepper motor 221 realizes the rotating shaft 23 to rotate back and forth at a certain angle through a rotation mechanism in one direction. The control structure is simpler and the cost is lower. In addition, the mounting base 21 includes a base plate 211 and two side plates 212 set on the top of the base plate 211. The transmission assembly 30 is set on the top of the base plate 211 and located between the two side plates 212. The stepper motor 221 is set on one of its side plates 212. The rotating shaft 23 passes through the two side plates 212 through bearings. The two swinging members 24 are located on the outside of the two side plates 212.

[0091] See Figure 7 As shown, the rotary drive device 22 includes an external rotor motor 223 and a first synchronous belt pulley reduction assembly 224 connected to the external rotor motor 223. The output end of the first synchronous belt pulley reduction assembly 224 is connected to the transmission assembly 30. The external rotor motor 223 makes the rotary drive device 22 quieter during operation, thereby reducing the impact on sleep. Specifically, the first synchronous belt pulley reduction assembly 224 includes two sets of first synchronous belt pulley reduction groups. The first synchronous belt pulley reduction groups are existing mature technologies and will not be described in detail here. The reduction ratio can be 1:6. The transmission assembly 30 and the external rotor motor 223 are both mounted on the top of the base plate 211 via a frame.

[0092] In some other embodiments, the transmission component 30 may also be a gear combination structure, that is, the rotary drive device 22 is connected to the driving gear, the driven gear is sleeved on the rotating shaft 23, the driving gear is connected to the driven gear through multiple meshing gears, and the rotary drive device 22 drives the rotating shaft 23 to rotate back and forth at a certain angle by forward and reverse rotation.

[0093] The mattress 50 includes a mattress body 51 and a mattress cover 52 fitted over the mattress body 51. The mattress 50 is positioned on top of the support frame assembly 43. A vibrator 80 is installed inside the mattress 50 and is connected to the control system 70. The vibrator 80 provides the mattress 50 with a vibration massage function. The pillow drive mechanism 20 and the bed frame 40 are spliced ​​and arranged on top of the support frame assembly 43. The pillow 10 covers the gap between the pillow drive mechanism 20 and the mattress 50.

[0094] The vibrator 80 includes a vibrating plate 81, a mounting bracket 20 disposed on the vibrating plate 81, and a vibrating motor 83 disposed on the mounting bracket 20. The vibrating plate 81 is provided with a plurality of first bolts 811 and a second bolt 812. Specifically, there are four first bolts 811 arranged in a square, and two second bolts 812 arranged symmetrically. The arrangement of the vibrating plate 81 allows the vibration of the vibrating motor 83 to be transmitted through the vibrating plate 81, resulting in better transmission effect and preventing the vibrating plate 81 from shifting when it is placed on the mattress 50.

[0095] See Figure 8 As shown, a cover 813 is provided on the vibrating plate 81, and the cover 813 is provided with an installation port 814 for mounting the mounting bracket 20. The installation port 814 is directly opposite the vibrating plate 81.

[0096] The mounting bracket 20 is located inside the cover 813. The mounting bracket 20 is installed inside the cover 813 through the installation port 814. The cover 813 is designed to separate the mattress 50 during installation, preventing the mattress 50 from interfering with the vibration motor 83 and affecting its operation. The mounting bracket 20 passes through the first bolt 811 and abuts against the vibration plate 81. The first bolt 811 is connected to a first nut 84 for fixing the mounting bracket 20 to the vibration plate 81. The mounting bracket 20 is installed on the vibration plate 81 through the bolt and nut cooperation structure, which is easy to disassemble and easy to maintain and replace. The mounting bracket 20 is provided with a foldable limiting part 801 on the side of the first nut 84 to prevent the first nut 84 from loosening. The rotation of the first nut 84 is restricted by the foldable limiting part 801. After the nut is fixed, the foldable limiting part 801 is folded to the side of the first nut 84, thereby preventing the mounting bracket 20 from loosening from the vibration plate 81 and ensuring good stability.

[0097] See Figure 9 As shown, specifically, the mounting frame 20 includes a horizontal plate 821 and a vertical plate 822 connected to the horizontal plate 821. The vibration motor 83 is arranged horizontally and mounted on the vertical plate 822. The horizontal plate 821 is provided with a supporting reinforcing plate 823 corresponding to the vertical plate 822. One end of the vibration motor 83 near the vertical plate 822 is fixedly connected to the vertical plate 822. A second bolt 812 is provided on the vibration plate 81. A fixing sleeve 85 passes through the second bolt 812. The second bolt 812 is connected to a second nut 86 for fixing the fixing sleeve 85 to the horizontal plate 821. The fixing sleeve 85 is located at the other end of the vibration motor 83 away from the vertical plate 822. The fixing sleeve 85 can prevent the vibration motor 83 from tilting up during use, so that the vibration motor 83 can be stably mounted on the mounting frame 20.

[0098] Furthermore, the mounting bracket 20 is provided with four mounting positions 802, the mounting positions 802 are inserted through the first bolt 811, and the foldable limiting parts 801 are arranged at intervals on the sides of the mounting positions 802.

[0099] Preferably, a rubber ring 90 is fitted on the other end of the vibration motor 83 away from the vertical plate 822, and the fixing sleeve 85 presses against the rubber ring 90. The rubber ring 90 can protect the vibration motor 83 during startup and prevent the fixing sleeve 85 from scratching the vibration motor 83. In this embodiment, the vibration motor 83 is a brushless motor. Compared with brushed motors, brushless motors have a longer lifespan and lower maintenance costs. The vibration motor 83 is connected to an oscillator 831.

[0100] See Figure 10 and Figure 11 As shown, the pad 80 includes a first PK cotton layer 511, an elastic layer 512, a second PK cotton layer 513, a 3D cotton layer 514, and a memory foam layer 515 arranged sequentially from bottom to top. The vibrating plate 81 is sandwiched between the elastic layer 512 and the second PK cotton layer 513. The elastic layer 512 has a clearance groove 501 for the cover 813 to pass through. The first PK cotton layer 511 covers the clearance groove 501. A PK cotton body 516 is also sandwiched between the cover 813 and the first PK cotton layer 511. The first PK cotton layer 511, the second PK cotton layer 513, and the PK cotton body 516 clamp and fix the vibrator to the pad 80. The PK cotton layer has a higher hardness than the elastic layer 512, so that the vibrator can be stably placed in the pad 80. The elastic layer 512 can be a sponge layer or a spring layer. PK cotton, 3D cotton, and memory foam are all existing known materials and will not be described in detail here.

[0101] The key design focus of this invention is:

[0102] Its main features include a back support frame and a first lifting mechanism. The first lifting mechanism can rotate the back support frame relative to the main frame, allowing the body to be in a more comfortable lying position. The control system also features a cervical spine reverse traction mode. The pillow drive mechanism drives the cervical support to swing up and down via a swinging component. In the cervical spine reverse traction mode, the first lifting mechanism and the pillow drive mechanism simultaneously reciprocate, enabling the cervical support to perform reverse traction correction on the neck, thus effectively treating and relieving cervical spondylosis. Furthermore, the strap is detachable, facilitating its assembly and preventing the head from leaving the head support area during the cervical spine reverse traction mode, ensuring the neck remains close to the support area and enhancing the massage effect of the cervical spine reverse traction.

[0103] Secondly, by incorporating a vibrating plate, the vibration of the vibrating motor is transmitted through the vibrating plate, resulting in better transmission. When the vibrating plate is placed on the mattress, it is less likely to shift. Furthermore, the vibrating motor is mounted on a mounting frame, which is installed on the vibrating plate using bolts and nuts, making it easy to disassemble, maintain, and replace. Additionally, the mounting frame is equipped with a foldable limiting part. After the nuts are secured, the foldable limiting part can be folded to the side of the first nut, thereby preventing the mounting frame from loosening from the vibrating plate and ensuring good stability.

[0104] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
