[0008] With the above structure, including a support base 1 and a rotating disc 2 connected to the support base 1, and the rotating disc 2 able to rotate and swing on the support base 1, the swivel chair is not only suitable for children to sit on, but children can also sit on the rotating disc 2 and rotate and swing the chair. This is especially beneficial for children with autism, as sitting on the rotating disc 2 and rotating and swinging the chair can provide vestibular training, stimulate the vestibular system, improve balance, and allow children to experience movement in space. Furthermore, children can track objects or patterns during the rotation and swinging process, thus training their vision.

[0009] In this embodiment, a first light-emitting part 3 is also included, which is connected to the rotating disk 2. The first light-emitting part 3 is disposed around the outer edge of the rotating disk 2 or on the bottom surface of the rotating disk. With this structure, the first light-emitting part 3, which is disposed around the outer edge of the rotating disk 2, provides the swivel chair with illumination. Furthermore, when the rotating disk 2 rotates, the first light-emitting part 3 rotates along with it, creating a running light effect, greatly increasing children's interest in the swivel chair. In some embodiments, the first light-emitting part is disposed on the bottom surface of the rotating disk, which effectively prevents the light emitted by the first light-emitting part from directly shining into children's eyes, making the light received by children softer, effectively protecting children's eyes, relieving eye fatigue, and extending the time children spend playing on the swivel chair.

[0010] In this embodiment, the rotating disk 2 has a first mounting groove 21 with a first opening 211. The first light-emitting part 3 is inserted into the first mounting groove 21 through the first opening 211. It also includes a light-transmitting first lampshade 31, which covers the first opening 211. The first light-emitting part 3 is an annular first light-emitting strip or a first LED bead 32. The first mounting groove 21 is an annular groove, and the first opening 211 is an annular opening. Through this structure, the installation of the first light-emitting part 3 is effectively achieved. Furthermore, because the first light-emitting part 3 is inserted into the first mounting groove 21 through the first opening 211, and because it includes a light-transmitting first lampshade 31 covering the first opening 211, not only is the rotating disk 2 kept flat, but the first light-emitting part 3 is also protected, extending its service life.

[0011] In this embodiment, a flexible seat cushion 4 is also included, which covers the surface of the rotating disc 2. With this structure, since the seat cushion 4 covers the surface of the rotating disc 2, children can sit more comfortably on the rotating disc 2 and swing around. Specifically, the seat cushion 4 can be a sponge cushion 4, a cloth cushion 4, a gel cushion 4, a silicone cushion 4, or a rubber cushion 4. The seat cushion also has a third perforated portion, which is aligned with the first perforated portion 41, and the shape of the third perforated portion is the same as the shape of the first perforated portion.

[0012] In this embodiment, the rotating disk 2 has a first hollow portion 22. Through the above structure, the first hollow portion 22 not only makes the rotating disk 2 more breathable, but also has a weight reduction effect, which facilitates the transportation of the swivel chair.

[0013] In this embodiment, the first hollow portion 22 is arranged circumferentially around the center of the rotating disk 2; the first hollow portion 22 includes at least a first hollow opening 221 and a second hollow opening 222, the first hollow opening 221 and the second hollow opening 222 having different shapes; the rotating disk 2 also has a handrail 23; the handrail 23 has hollowed-out handle holes. Through the above structure, because the first hollow opening 221 and the second hollow opening 222 have different shapes, children can train their tracking ability by observing the first hollow opening 221 and the second hollow opening 222 when rotating the rotating disk 2, and can complete some games using the different shaped first hollow opening 221 and the second hollow opening 222. For example, during the rotation of the rotating chair, the person giving the instructions calls out to click the first hollow opening 221 or the second hollow opening 222, and the executor must accurately click the first hollow opening 221 or the second hollow opening 222 according to the instructions to complete the game, thereby effectively training the child's hand-eye coordination and tracking ability.

[0014] In this embodiment, the surface of the rotating disc 2 has a recessed decorative pattern portion 24. With this structure, the recessed decorative pattern portion 24 rotates with the swivel chair, greatly enhancing the visual effect of the rotating disc 2 and significantly increasing children's interest in the swivel chair.

[0015] In this embodiment, the decorative pattern portion 24 is arranged circumferentially around the center of the rotating disk 2; the decorative pattern portion 24 includes at least a first pattern 241 and a second pattern 242, the first pattern 241 and the second pattern 242 having different shapes. With this structure, because the first pattern 241 and the second pattern 242 have different shapes, children can train their tracking ability by observing the first pattern 241 and the second pattern 242 while rotating the rotating disk 2, and can complete some games using the different shapes of the first pattern 241 and the second pattern 242. For example, during the rotation of the rotating chair, the person giving the instructions calls out to click the first pattern 241 or the second pattern 242, and the player must accurately click the first pattern 241 or the second pattern 242 according to the instructions to complete the game, thereby effectively training the child's hand-eye coordination and tracking ability.

[0016] In this embodiment, a second light-emitting part 5 is also included, which is connected to the support base 1. With the above structure, because of the second light-emitting part 5, when the rotating disc 2 rotates, the child sitting on the rotating disc 2 rotates relative to the second light-emitting part 5, so that the second light-emitting part 5 observed by the child during the rotation has a marquee effect, greatly increasing the child's interest in the rotating chair.

[0017] In this embodiment, the second light-emitting portion 5 is disposed around the outer edge of the support base 1 or on the top surface of the support base 1; the support base 1 has a second mounting groove 11, the second mounting groove 11 has a second slot 111, and the second light-emitting portion 5 is inserted into the second mounting groove 11 through the second slot 111; it also includes a light-transmitting second lampshade 51, the second lampshade 51 covering the second slot 111; the second light-emitting portion 5 is an annular second light-emitting strip or a second LED bead 52, the second mounting groove 11 is an annular second mounting groove 11, and the second slot 111 is an annular second slot 111. Through the above structure, the installation of the second light-emitting portion 5 is effectively realized, and because the second light-emitting portion 5 is inserted into the second mounting groove 11 through the second slot 111; and because it also includes a light-transmitting second lampshade 51 covering the second slot 111, not only is the support base 1 kept flat, but the second light-emitting portion 5 is also protected, extending the service life of the second light-emitting portion 5. In some embodiments, the second light-emitting portion is disposed on the top surface of the support base, which can effectively prevent the light emitted by the second light-emitting portion from being blocked by the support base.

[0018] In this embodiment, the support base 1 has a second hollow portion 16. The second hollow portion 16 includes at least a third hollow opening 221 and a fourth hollow opening 222. The third hollow opening 221 and the fourth hollow opening 222 have the same shape and are symmetrically arranged. Through this structure, the third hollow opening 221 and the fourth hollow opening 222 can effectively reduce the weight of the support base 1, facilitating its transportation. Furthermore, because the third hollow opening 221 and the fourth hollow opening 222 have the same shape and are symmetrically arranged, the support base 1 is left-right symmetrical, preventing the center of gravity of the support base 1 from shifting, thus allowing the support base 1 to be more stably supported on the bottom surface, thereby enabling the support base 1 to more stably support the rotating disk 2.

[0019] In this embodiment, the swivel chair also includes a sound device 6. This structure allows the swivel chair to emit sound, such as music, during rotation, enabling children to rotate to the rhythm of the music and thus train their hearing. Specifically, the sound device 6 is a loudspeaker.

[0020] This embodiment also includes a switch device 7 and a control motherboard 71. The switch device 7, the sound device 6, and the first light-emitting part 3 are all electrically connected to the control motherboard 71. The switch device 7 is used to control the sound device 6 and the first light-emitting part 3 to be turned on or off. With the above structure, the sound device 6 and the first light-emitting part 3 can be selectively turned on or off by the switch device 7 to meet the user's needs in different scenarios. For example, at night, turning on the sound device 6 may disturb the neighbors, so the sound device 6 can be turned off.

[0021] In this embodiment, the switching device 7 is a push button switch 703, a toggle switch 704, a touch sensor switch 705, a push button switch 706, a rotary switch sensor 707, a gravity sensor switch 701, or a micro switch 702. Through the above structure, the switching device 7 is effectively installed, allowing for the selective installation of different types of switching devices 7 on the swivel chair, so that the swivel chair can be turned on or off using different switching devices 7.

[0022] In this embodiment, a switching device 8 is also included. The switching device 8, the sound device 6, and the first light-emitting part 3 are all electrically connected to the control motherboard 71. The switching device 8 is used to switch the sound device 6 and the first light-emitting part 3 between a first mode and a second mode. When the switching device 8 switches the sound device 6 and the first light-emitting part 3 to the first mode, the sound device 6 is turned off and the first light-emitting part 3 is turned on. When the switching device 8 switches the sound device 6 and the first light-emitting part 3 to the second mode, the sound device 6 is turned on and the first light-emitting part 3 is turned off. Through the above structure, the needs of children to use the swivel chair in various scenarios can be met by switching between different modes.

[0023] This embodiment also includes a control motherboard, a Bluetooth module 708, and a Bluetooth pairing button 709. The Bluetooth module is electrically connected to the control motherboard, the sound device, and the first light-emitting part. With this structure, the user can also pair the Bluetooth module with a mobile terminal device via the Bluetooth pairing button. After successful pairing, the user can remotely control the sound device and / or the first light-emitting part to turn on or off via the mobile terminal device.

[0024] In this embodiment, a voice recognition module 72, a switch device 7, and a control motherboard 71 are also included. The voice recognition module 72, the switch device 7, the sound device 6, and the first light-emitting part 3 are all electrically connected to the control motherboard 71. When the switch device 7 is pressed for a long time, it controls the voice recognition module 72 to turn on or off. When the switch device 7 is pressed for a short time, it switches the sound device 6 and the first light-emitting part 3 to voice control mode. When the voice recognition module 72 detects voice matching a first preset audio, it controls the first light-emitting part 3 to turn on. When the voice recognition module 72 detects voice matching a second preset audio, it controls the first light-emitting part 3 to turn on. When a voice recognition module 72 detects a voice matching a third preset audio, it controls the first light-emitting part 3 to turn off; when it detects a voice matching a fourth preset audio, it controls the sound device 6 to turn off; when it detects a voice matching a fifth preset audio, it controls the first light-emitting part 3 and the sound device 6 to turn on; when it detects a voice matching a sixth preset audio, it controls the first light-emitting part 3 and the sound device 6 to turn off. This structure allows the user to control the swivel chair via voice, where the first preset audio is for turning on the first light-emitting part 3, the second preset audio is for turning on the sound device 6, the third preset audio is for turning off the first light-emitting part 3, the fourth preset audio is for turning off the sound device 6, the fifth preset audio is for turning on both the first light-emitting part 3 and the sound device 6, and the sixth preset audio is for turning off both the first light-emitting part 3 and the sound device 6.

[0025] In this embodiment, the switching device 7 is a gravity sensor switch 701, which is a resistance strain gauge gravity sensor switch 701. The resistance strain gauge gravity sensor switch 701 includes an elastic body 73, a resistance strain gauge 74, and a detection circuit 75. The resistance strain gauge 74 is bonded to the elastic body 73. Under the action of external force, the elastic body 73 undergoes elastic deformation, causing the resistance strain gauge 74 bonded to the elastic body 73 to also deform, thereby changing the resistance value of the resistance strain gauge 74. The detection circuit 75 converts the resistance change into an electrical signal to turn the sound device 6 and / or the first light-emitting part on or off by detecting the change in gravity. The support base 1 is divided into three parts; it includes a base portion 12 and a first support rod portion 13, the base portion 12 being connected to the first support rod portion 13, and also includes a second support rod portion 14, which is detachably connected to the rotating disk 2; the second support rod portion 14 is sleeved and connected to the first support rod portion 13, and the second support rod portion 14 can rotate on the first support rod portion 13; a resistance strain gauge gravity sensor switch 701 is disposed between the first support rod portion 13 and the second support rod portion 14, and the second support rod portion 14 or the second support rod portion 14 abuts against the elastic body 73 of the resistance strain gauge gravity sensor switch 701. The above structure effectively realizes the setting of the switch device 7. When a child sits on the swivel chair, the gravity sensor switch 701 senses the change in gravity and automatically turns on the sound device 6 and / or the first light-emitting part 3 without manual adjustment. When the child leaves the swivel chair, the gravity sensor switch 701 senses the change in gravity and automatically turns off the sound device 6 and / or the first light-emitting part 3 to save energy and make it safer, preventing the situation where the child forgets to turn off the switch after using the swivel chair.

[0026] In this embodiment, the rotating disk 2 and the supporting base 1 are set at an inclined angle; the diameter of the first hollow portion 22 ranges from 1mm to 1000mm; the width of the rotating disk (2) ranges from 1mm to 1000mm; the width of the supporting base (1) ranges from 1mm to 1000mm; and the height of the swivel chair ranges from 1mm to 1000mm. Specifically, the width of the rotating disk 2 ranges from 200mm to 600mm; the width of the supporting base 1 ranges from 200mm to 600mm; and the height of the swivel chair ranges from 1mm to 500mm. Through the above structure, the swivel chair within this size range can effectively match different user groups and maintain the breathability of the swivel chair. Furthermore, because the rotating disk 2 and the supporting base 1 are set at an inclined angle, children sitting on the rotating disk 2 can make the swivel chair rotate automatically by their own weight, allowing children to more easily rotate and sway on the rotating disk 2. The rotating disk 2 and the supporting base 1 are set at an acute angle, an obtuse angle, or a right angle.

[0027] In this embodiment, a plurality of reinforcing ribs 141 extend from the sidewall of the second support rod portion 14; specifically, the plurality of reinforcing ribs 141 are arranged sequentially around the sidewall of the second support rod portion 14; the reinforcing ribs 141 are triangular in shape. Through the above structure, the reinforcing ribs 141 can effectively improve the strength of the second support rod, so that the second support rod can more stably support the rotating disk 2.

[0028] In this embodiment, a first connector 142 is also included. A support plate 143 is provided on the second support rod portion 14. The bottom of the rotating disk 2 has multiple mounting posts 25. The support plate 143 has multiple first mounting holes 144, and the mounting posts 25 have second mounting holes 251. The first connector 142 passes through the first mounting holes 144 and the second mounting holes 251 in sequence to connect the support plate 143 to the rotating disk 2. A stop protrusion 26 extends from the bottom of the rotating disk 2, forming a limiting groove 261. The mounting posts 25 are located within the limiting groove 261, and the support plate 143 is located within the limiting groove 261. The top surface of the support plate 143 abuts against the bottom surface of the mounting posts 25. With the above structure, since the mounting column 25 is located in the limiting groove 261 and the support plate 143 is located in the limiting groove 261, the top surface of the support plate 143 abuts against the bottom surface of the mounting column 25, effectively completing the connection between the second support rod part 14 and the base, preventing the position of the support rod and the base from shifting, and the design of the support plate 143 effectively increases the contact surface between the second support rod and the rotating disk 2, making the connection between the second support rod part 14 and the base more stable.

[0029] In this embodiment, the support base 1 has a receiving cavity 15 for accommodating electronic components. With the above structure, electronic components such as sound devices and batteries can be housed within the receiving cavity 15, effectively protecting these components.

[0030] In this embodiment, the rotating disk is a circular rotating disk, an airplane-shaped rotating disk, a butterfly-shaped rotating disk, an elliptical rotating disk, a fish-shaped rotating disk, a flower-shaped rotating disk, a penguin-shaped rotating disk, a cloud-shaped rotating disk, a claw-shaped rotating disk, a bowl-shaped rotating disk, a dinosaur-shaped rotating disk, a turtle-back-shaped rotating disk, or a rocket-shaped rotating disk.
