Description

Technical Field

[0001] The invention relates to the technical field of child safety seats, in particular to a child safety seat with an electric rotation function. Background Art

[0002] With the continuous upgrading of consumption and industry technology, parents are paying more and more attention to the safety and convenience of children sitting in child safety seats, especially child seats that combine safety and convenience are widely welcomed by parents.

[0003] The patent with the patent announcement number CN220700964U discloses a child safety seat with an electric rotation function, including a base, a rotating disk, an electric transmission assembly and a mounting cavity, wherein the rotating disk is rotationally connected to the base; the rotating disk is provided with a mounting cavity, or the base is provided with a mounting cavity, or a mounting cavity is provided between the rotating disk and the base; the electric transmission assembly is installed in the mounting cavity, the electric transmission assembly is connected to the base, and the electric transmission assembly is transmission-connected to the rotating disk to realize the electric rotation function. By utilizing the mounting cavity, the electric transmission assembly is arranged inside the mounting cavity, which can more reasonably lay out the seat structure, and there is no need to change the appearance of the child safety seat, which can reasonably utilize the space of the structure itself and maintain the compactness of the overall structure; and the mounting cavity is located at the bottom of the seat, so that when designing the structure of the electric transmission assembly, there is no need to consider the tilt angle of the seat, that is, no matter how the seat is tilted, it will not affect the normal operation of the electric transmission assembly, and the improvement is easy to achieve.

[0004] However, the device still has some shortcomings: the device can realize the rotation function of the seat, but the height of the device is difficult to raise and lower freely, resulting in parents driving alone and needing to carry the child out of the seat or bend over to adapt to the seat height when feeding the child. This increases the parents' workload and the feeding time of the child, resulting in long delays on the road and increased driving fatigue. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a child safety seat with an electric rotation function, which solves the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a child safety seat with an electric rotation function, comprising a device body, and a plurality of ventilation holes are opened at the bottom of the device body, protective pads are arranged on both sides of the inner wall of the device body, two safety belts are arranged on the vertical surface of the inner wall of the device body, a headrest is arranged above the vertical surface of the inner wall of the device body, and the headrest is located above the safety belt, an electric push rod is fixedly installed at the bottom of the device body, the top of the telescopic end of the electric push rod is fixedly connected to the bottom of the device body, a turntable is fixedly installed at the bottom of the electric push rod, a telescopic component is rotatably installed at the bottom of the turntable, and the telescopic component has a built-in micro motor , and a slide groove is arranged inside the telescopic end of the telescopic component, the top of the micro-motor output end is fixedly connected to the bottom of the turntable, two telescopic rods are fixedly installed at the top edge of the turntable, and the tops of the two telescopic ends of the telescopic rods are fixedly installed at the bottom of the device body, the telescopic rods are symmetrically distributed around the axis of the turntable, and the telescopic rods are built with springs, and the outer wall of the telescopic end of the telescopic rod away from the center of the turntable is hinged with an oblique rod through a torsion spring, and the bottom of the oblique rod is in contact with the inner wall of the slide groove of the telescopic end of the telescopic component, and a hollow plate is fixedly installed on the outer wall of the telescopic end of the telescopic rod close to the center of the turntable, and a U-shaped plate is penetrated and slidably installed inside the hollow plate close to the center of the turntable, and the top of the U-shaped plate is connected to the hollow plate A spring is arranged between the inside, and a plurality of buffer plates are fixedly installed on the outer wall of the telescopic rod near the center of the turntable. The main body of the device is installed in the rear seat of the car, and the child sits inside the main body of the device, that is, inside the protective pad and the headrest, and wears a seat belt. When the parents drive out alone and need to feed the child, the motor inside the telescopic component is started, and the output end of the motor drives the turntable to rotate, and the turntable drives the electric push rod to rotate. When the electric push rod rotates, its telescopic end drives the main body of the device to rotate to the direction facing the car door. When the height of the child needs to be adjusted to an appropriate feeding height, the electric push rod is started, and the telescopic end of the electric push rod drives the main body of the device to rise to the height required by the parents and then stops rising; and when the child is in the car, the electric push rod is driven by the electric push rod. In order to prevent children from feeling bored when riding in the vehicle, the telescopic end of the electric push rod is not set to a limit state but a buffer contraction state within a certain range. Therefore, when the child moves up and down due to boredom, the device body is pressed downward by gravity. When the device body presses the telescopic end of the electric push rod downward, it also presses the telescopic end of the telescopic rod synchronously. The telescopic end of the telescopic rod contracts downward due to gravity. When the telescopic end of the telescopic rod moves downward, it drives the inclined rod to move synchronously. At this time, the hinge shaft between the inclined rod and the telescopic end of the telescopic rod starts to rotate and moves away from the center of the electric push rod. The inclined rod pushes the telescopic end of the telescopic assembly to move synchronously, and when the telescopic rod is reset by the spring elastic force, the inclined rod is reset by the torsion spring, and so on.When the telescopic end of the telescopic rod contracts downward, it drives the hollow plate to move synchronously, and the hollow plate drives the U-shaped plate to move synchronously. When the U-shaped plate moves downward, its own arc surface will resist the buffer plate to generate a resistance force. At this time, the top of the U-shaped plate extends outward from the inside of the hollow plate through the resistance force. When the arc surface of the bottom of the U-shaped plate passes over the buffer plate, it is reset by the spring elastic force. At this time, the U-shaped plate will be re-stuck in the adjacent inside of the next buffer plate. ;

[0007] According to the above technical solution, the plurality of buffer plates are equidistantly distributed, and the arc surface of the outer wall of the buffer plate is located on the arc motion trajectory of the bottom of the U-shaped plate. An anti-infection device is provided above the turntable to prevent children from sweating when riding in the vehicle for a long time, thereby increasing the friction between the children's skin and the leather surface of the device body due to sweat stains, thereby increasing the possibility of children's skin allergies.

[0008] According to the above technical scheme, the anti-infection device includes a transmission plate, a cooling component and an ultraviolet lamp. The bottom of the transmission plate is hinged to the left side of the outer wall of the telescopic rod through a torsion spring, and the front and back sides of the cooling component are hinged to the vertical surface of the inner wall of the transmission plate through torsion springs. The top of the cooling component is in contact with the bottom surface of the device body, and the cooling component is equipped with a built-in wireless module that can be controlled by Bluetooth. Several ultraviolet lamps are fixedly installed on the edges of the inner walls on the left and right sides of the cooling component, and the ultraviolet lamps are connected to the cooling component. When the device body moves downward, it contacts the telescopic end of the telescopic rod to retract downward, and the device body synchronously contacts the cooling component, and the hinge shaft between the cooling component and the transmission plate starts to rotate. At the same time, the hinge shaft between the transmission plate and the telescopic rod rotates synchronously to cause the cooling component to slide to the left along the bottom plane of the device body, and the cooling component drives the ultraviolet lamp to move synchronously.

[0009] According to the above technical scheme, the anti-infection device also includes two horizontal plates, a rotating wheel and an octagonal reflective plate. The right sides of the two horizontal plates are fixedly installed at the left edge of the cooling assembly, and the horizontal plates are symmetrically distributed around the axis of the cooling assembly. The vertical surface of the outer wall of the rotating wheel is rotatably installed on the vertical surface of the inner wall of the horizontal plate, and the outer wall of the rotating wheel is in contact with the bottom of the device body. The octagonal reflective plates are equidistantly and rotatably installed on the vertical surface of the inner wall of the rotating wheel through springs. When the cooling assembly slides, it drives the horizontal plates to move synchronously, and the horizontal plates drive the rotating wheel to move synchronously and contact with the bottom of the device body to generate friction. At this time, the rotating wheel starts to rotate through friction, and when the rotating wheel rotates, it drives the octagonal reflective plate to make a circular motion.

[0010] According to the above technical solution, the anti-infection device also includes a fixed rod and a plurality of resistance plates, the front and back ends of the fixed rod are fixedly installed at the center of the inner wall of the rotating wheel, the plurality of resistance plates are equidistant and fixedly installed on the outer wall surface of the fixed rod, and the arc surface of the resistance plate is in contact with the inclined surface of the octagonal reflector plate, and a circulation device for fanning the air under the device body to smoothly prevent sweat from corroding the inside of the device body and causing bacterial reproduction is provided at the periphery of the cooling component. At the same time, when the rotating wheel rotates, the fixed rod is driven to rotate, and when the fixed rod rotates, the resistance plate is driven to rotate and resist the inclined surface of the octagonal reflector plate to generate thrust. At this time, the octagonal reflector plate slides away from the center of the rotating wheel through the thrust, and then the octagonal reflector plate is reset by the spring force and repeats this process repeatedly.

[0011] According to the above technical scheme, the circulation device includes a reciprocating screw, a sliding ring and a fan plate, the reciprocating screw is fixedly installed at the center of the vertical surface of the outer wall of the rotating wheel at one end near the center of the turntable, the inner wall of the sliding ring penetrates and is slidably installed on the outer wall surface of the reciprocating screw, the top of the fan plate is slidably installed at the bottom edge of the device body through a spring, and a sliding groove is provided on the outer wall of the fan plate, and the vertical surface of the fan plate near the center of the cooling component is fixedly connected to the vertical surface of the outer wall of the sliding ring. When the rotating wheel rotates, it drives the reciprocating screw to rotate, and when the reciprocating screw rotates, the reciprocating spiral groove of its outer wall restricts the sliding ring. At the same time, the limit block inside the sliding ring continuously contacts the spiral groove of the outer wall of the reciprocating screw, so that the sliding ring can slide back and forth along its surface when the reciprocating screw rotates, and when the sliding ring slides, it pushes the fan plate to slide synchronously along the bottom of the device body, and when the fan plate slides reciprocatingly, it fans the bottom of the device body and the surrounding air.

[0012] According to the above technical scheme, the circulation device also includes a rotating rod, a fixed ring, a telescopic plate and a plurality of activated carbon plates. The rotating rod is rotatably installed at one end away from the center of the cooling assembly on the vertical surface of the inner wall of the fanning plate, and a spiral groove is opened on the outer wall of the rotating rod. The inner wall of the fixed ring penetrates and is slidably installed on the surface of the spiral groove on the outer wall of the rotating rod. The bottom of the telescopic plate is fixedly installed on the top of the telescopic assembly, and the telescopic end of the telescopic plate is fixedly installed on the bottom of the outer wall of the fixed ring. Several activated carbon plates are equidistant and fixedly installed on the outer wall surface of the rotating rod. When the fanning plate slides back and forth, it drives the rotating rod to move synchronously. When the rotating rod slides back and forth, the non-self-locking spiral groove on its outer wall contacts the block on the inner wall of the fixed ring through the contact between the rotating rod and the fixed ring, prompting the rotating rod to generate a rotational force and start to rotate. The telescopic plate limits the fixed ring, and at the same time, the rotating rod drives the activated carbon plate to rotate.

[0013] According to the above technical solution, the circulation device also includes a limit plate and a plurality of L-shaped plates. The limit plate is rotatably installed on the vertical surface of the outer wall of the rotating rod on the side away from the center of the cooling component through a torsion spring. The plurality of L-shaped plates are equidistant and fixedly installed on the outer wall surface of the limit plate. The L-shaped plate is located on the movement trajectory of the edge of the activated carbon plate close to the center of the cooling component, and the L-shaped plate has toughness. When the rotating rod rotates, the limit plate remains stationary. At this time, the activated carbon plate rotates and hits the L-shaped plate. The L-shaped plate forms resistance to the activated carbon plate through the torsion force of the torsion spring between the limit plate and the rotating rod, thereby increasing the impact force of the activated carbon plate and causing the activated carbon plate to vibrate.

[0014] The present invention provides a child safety seat with an electric rotation function, which has the following beneficial effects:

[0015] (1) The present invention cooperates with an electric push rod, a turntable, a telescopic component, a telescopic rod, a diagonal rod, a hollow plate, a U-shaped plate and a buffer plate. Firstly, it is different from traditional child seats that require parents to hold their children out of the seats or bend down to adapt to the seat height. This reduces the workload of parents to a certain extent and shortens the feeding time of children in a more comfortable posture, thus avoiding long delays on the road and increasing parents' driving fatigue. Secondly, it increases the contact area between the telescopic component and the car seat when the child moves up and down inside the device body, diverting the child's attention and improving the boring riding environment while improving the overall stability and safety of the device body. Finally, it realizes step-by-step limit processing during movement on the device body, realizing multi-level limit protection, avoiding excessive up and down movement range that brings discomfort to children's riding experience, and at the same time reducing the loss of the device body to avoid sudden damage.

[0016] (2) The present invention, through the setting of the anti-infection device, cooperates with the transmission plate, cooling assembly, ultraviolet lamp, horizontal plate, rotating wheel, octagonal reflector, fixed rod and contact plate to expand the range of movement of the cooling assembly and the ultraviolet lamp, and blows and irradiates through the ventilation holes of the device body to prevent children from sweating when riding in the vehicle for a long time, thereby increasing the friction between the children's skin and the leather surface of the device body due to sweat stains, and increasing the possibility of children's skin allergies; and the octagonal reflector refracts the light of the ultraviolet lamp in a circular and sliding manner, so that the ultraviolet lamp covers a wider range of the entire device body, avoiding the existence of shadow angles that cause bacterial reproduction and endanger children's skin health.

[0017] (3) The present invention, through the arrangement of a circulation device, cooperates with a rotating wheel, a reciprocating screw, a sliding ring, a fan plate, a rotating rod, a fixed ring, a telescopic plate, an activated carbon plate, a limit plate and an L-shaped plate. Firstly, the gas circulation rate around the device body is accelerated to drive the salt generated when sweat evaporates, and at the same time, the diffusion rate of the cold air of the cooling component is accelerated to avoid the corrosion of the inside of the device body during the natural volatilization of sweat and increase the possibility of mildew; secondly, the activated carbon plate is prompted to absorb the harmful odor emitted by the leather of the device body due to summer sunlight, to avoid the health effects of children inhaling the harmful odor, and provide a safe riding environment for children; finally, the activated carbon plate is prompted to use vibration force to make the absorption process of the harmful odor by the activated carbon inside itself more uniform, to avoid the excessive saturation of the absorption of the harmful odor by individual activated carbon plates, resulting in secondary overflow of the harmful odor, and to a certain extent to extend the replacement cycle of the activated carbon plate.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-Figure 9One embodiment of the present invention is: a child safety seat with an electric rotation function, comprising a device body 1, and a plurality of vents are opened at the bottom of the device body 1, protective pads 2 are arranged on both sides of the inner wall of the device body 1, two safety belts 3 are arranged on the vertical surface of the inner wall of the device body 1, a headrest 31 is arranged above the vertical surface of the inner wall of the device body 1, and the headrest 31 is located above the safety belt 3, an electric push rod 6 is fixedly installed at the bottom of the device body 1, the top of the electric push rod 6 is fixedly connected to the bottom of the device body 1, and a turntable 7 is fixedly installed at the bottom of the electric push rod 6. A telescopic assembly 8 is rotatably installed at the bottom of the disk 7, and a micro-motor is built into the telescopic assembly 8. A slide groove is arranged inside the telescopic end of the telescopic assembly 8. The top of the micro-motor output end is fixedly connected to the bottom of the turntable 7. Two telescopic rods 9 are fixedly installed at the top edge of the turntable 7. The tops of the telescopic ends of the two telescopic rods 9 are fixedly installed at the bottom of the device body 1. The telescopic rods 9 are symmetrically distributed around the axis of the turntable 7, and a spring is built into the telescopic rods 9. The outer wall of the telescopic end of the telescopic rod 9 away from the center of the turntable 7 is hinged with an inclined rod 10 through a torsion spring. The bottom of the inclined rod 10 is connected to the inner wall of the slide groove at the telescopic end of the telescopic assembly 8. A hollow plate 11 is fixedly installed on the outer wall of the telescopic end of the telescopic rod 9 near the center of the turntable 7, a U-shaped plate 12 is penetrated and slidably installed inside the hollow plate 11 near the center of the turntable 7, a spring is arranged between the top of the U-shaped plate 12 and the inside of the hollow plate 11, and a plurality of buffer plates 13 are fixedly installed on the outer wall of the telescopic rod 9 near the center of the turntable 7. The above cooperation is different from the traditional child seat which requires the child to be carried out of the seat or the child to bend down to adapt to the seat height, which reduces the labor workload of parents to a certain extent, and shortens the feeding time of the child in a more comfortable posture. The above coordination can expand the contact area between the telescopic component 8 and the car seat when the child moves up and down inside the device body 1, divert the child's attention, improve the boring riding environment, and enhance the overall stability and safety of the device body 1; the above coordination can realize the step-by-step limit processing of the movement on the device body 1, realize multi-level limit protection, avoid the excessive up and down movement range that brings discomfort to the child's riding experience, and reduce the loss of the device body 1 to avoid sudden damage.

[0030] A plurality of buffer plates 13 are distributed at equal intervals, and the arc surface of the outer wall of the buffer plate 13 is located on the arc motion trajectory of the bottom of the U-shaped plate 12. An anti-infection device 4 is provided above the turntable 7 to prevent children from sweating when riding in the vehicle for a long time, thereby increasing the friction between the child's skin and the leather surface of the device body 1 due to sweat stains, thereby increasing the possibility of children's skin allergies.

[0031] When in use, the device body 1 is installed in the rear seat of the car, and the child sits inside the device body 1, that is, inside the protective pad 2 and the headrest 31, and fastens the seat belt 3. When the parents drive alone and need to feed the child, the motor inside the telescopic component 8 is started, and the output end of the motor drives the turntable 7 to rotate, and the turntable 7 drives the electric push rod 6 to rotate. When the electric push rod 6 rotates, its telescopic end drives the device body 1 to rotate to the direction facing the car door. When the height of the child needs to be adjusted to an appropriate feeding height, the electric push rod 6 is started, and the telescopic end of the electric push rod 6 drives the device body 1 to rise to the height required by the parents and then stops rising. The above cooperation is different from the traditional child feeding chair. The seat requires the parents to carry the child out of the seat or bend over to adapt to the seat height, which reduces the workload of parents to a certain extent, shortens the feeding time of the child in a more comfortable posture, avoids long delays on the road and increases the driving fatigue of parents; and in order to prevent the child from feeling bored while riding in the vehicle, the telescopic end of the electric push rod 6 is not set to a limit state but a buffer contraction state within a certain range. Therefore, when the child moves up and down due to boredom, the device body 1 is pressed downward by gravity. When the device body 1 presses the telescopic end of the electric push rod 6 downward, it also presses the telescopic end of the telescopic rod 9. The telescopic end of the telescopic rod 9 is contracted downward by gravity. When the telescopic end of the telescopic rod 9 contracts downward, it drives the inclined rod 10 to move synchronously. At this time, the hinge shaft between the inclined rod 10 and the telescopic end of the telescopic rod 9 starts to rotate and moves away from the center of the electric push rod 6. The inclined rod 10 pushes the telescopic end of the telescopic assembly 8 to move synchronously, and when the telescopic rod 9 is reset by the elastic force of the spring, the inclined rod 10 is reset by the torsion spring, and so on. Through the above cooperation, the contact area between the telescopic assembly 8 and the car seat is expanded when the child moves up and down inside the device body 1, the child's attention is diverted to improve the boring riding environment, and the overall stability and safety of the device body 1 are improved; when the telescopic end of the telescopic rod 9 contracts downward, it drives the hollow plate 11 to move synchronously When the U-shaped plate 12 moves, the hollow plate 11 drives the U-shaped plate 12 to move synchronously. When the U-shaped plate 12 moves downward, its own arc surface will resist the buffer plate 13 to generate a resistance force. At this time, the top of the U-shaped plate 12 extends outward from the inside of the hollow plate 11 through the resistance force. When the arc surface of the bottom of the U-shaped plate 12 passes over the buffer plate 13, it is reset by the spring force. At this time, the U-shaped plate 12 will be re-stuck in the adjacent inside of the next buffer plate 13. Through the above cooperation, the movement on the device body 1 is limited step by step, and multi-level limit protection is realized to avoid excessive up and down movement, which brings discomfort to the children's riding experience. At the same time, the loss of the device body 1 is reduced to avoid sudden damage.

[0032] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes an infection prevention device 4;

[0033] The anti-infection device 4 includes a transmission plate 41, a cooling component 42 and an ultraviolet lamp 43. The bottom of the transmission plate 41 is hinged to the left side of the outer wall of the telescopic rod 9 by a torsion spring, and the front and back sides of the cooling component 42 are hinged to the vertical surface of the inner wall of the transmission plate 41 by torsion springs. The top of the cooling component 42 is in contact with the bottom surface of the device body 1, and the cooling component 42 is equipped with a wireless module that can be controlled by Bluetooth. Several ultraviolet lamps 43 are fixedly installed on the inner wall edges on both sides of the cooling component 42, and the ultraviolet lamps 43 are connected to the cooling component 42. The above coordination expands the activity range of the cooling component 42 and the ultraviolet lamp 43, and air is blown and irradiated through the ventilation holes of the device body 1 to prevent children from sweating while riding in the vehicle for a long time, thereby increasing the friction between the children's skin and the leather surface of the device body 1 due to sweat stains, thereby increasing the possibility of children's skin allergies.

[0034] The anti-infection device 4 also includes two horizontal plates 44, a rotating wheel 45 and an octagonal reflector 46. The right sides of the two horizontal plates 44 are fixedly installed on the left edge of the cooling component 42, and the horizontal plates 44 are symmetrically distributed around the axis of the cooling component 42. The vertical surface of the outer wall of the rotating wheel 45 is rotatably installed on the vertical surface of the inner wall of the horizontal plate 44, and the outer wall of the rotating wheel 45 is in contact with the bottom of the device body 1. The octagonal reflectors 46 are equidistantly and rotatably installed on the vertical surface of the inner wall of the rotating wheel 45 through springs.

[0035] The anti-infection device 4 also includes a fixed rod 47 and a plurality of contact plates 48. Both ends of the fixed rod 47 are fixedly installed at the center of the inner wall of the rotating wheel 45. The plurality of contact plates 48 are equidistant and fixedly installed on the outer wall surface of the fixed rod 47. The arc surface of the contact plate 48 contacts the inclined surface of the octagonal reflector 46. A circulation device 5 is provided at the periphery of the cooling component 42 to fan the air under the device body 1 smoothly to prevent sweat from corroding the inside of the device body 1 and causing bacterial reproduction. Through the above cooperation, the octagonal reflector 46 is prompted to perform circular and sliding refraction of the light of the ultraviolet lamp 43, so that the ultraviolet lamp 43 has a wider overall coverage range of the device body 1 to avoid the existence of shadow angles that cause bacterial reproduction and endanger children's skin health.

[0036] When in use, the device body 1 moves downward, and the telescopic end of the telescopic rod 9 shrinks downward, and the device body 1 synchronously resists the cooling component 42, and the hinge shaft between the cooling component 42 and the transmission plate 41 starts to rotate. At the same time, the hinge shaft between the transmission plate 41 and the telescopic rod 9 rotates synchronously to cause the cooling component 42 to slide to the left along the bottom plane of the device body 1, and the cooling component 42 drives the ultraviolet lamp 43 to move synchronously. The above cooperation expands the activity range of the cooling component 42 and the ultraviolet lamp 43, and blows and irradiates through the ventilation holes of the device body 1 to prevent children from sweating when riding in the vehicle for a long time, thereby increasing the friction between the child's skin and the leather surface of the device body 1 due to sweat stains, and increasing the possibility of children's skin allergies; when the cooling component 42 slides, it drives the horizontal plate 44 to move synchronously, and the horizontal plate 44 drives the rotating wheel 45 to move synchronously and contacts with the bottom of the device body 1 to generate friction. At this time, the rotating wheel 45 starts to rotate due to the friction. When the rotating wheel 45 rotates, it drives the octagonal reflector 46 to make a circular motion. At the same time, when the rotating wheel 45 rotates, it drives the fixing rod 47 to rotate. When the fixing rod 47 rotates, it drives the contact plate 48 to rotate and contacts the inclined surface of the octagonal reflector 46 to generate thrust. At this time, the octagonal reflector 46 slides away from the center of the rotating wheel 45 through the thrust. Then the octagonal reflector 46 is reset by the spring elastic force and reciprocates. Through the above cooperation, the octagonal reflector 46 is prompted to perform a circular and sliding refraction of the light of the ultraviolet lamp 43, so that the ultraviolet lamp 43 has a wider overall coverage of the device body 1 to avoid the existence of shadow angles that cause bacteria to multiply and endanger children's skin health.

[0037] See also Figure 1-Figure 9 , based on the above embodiment, another embodiment of the present invention further includes a circulation device 5;

[0038] The circulation device 5 includes a reciprocating screw 51, a sliding ring 52 and a fanning plate 53. The reciprocating screw 51 is fixedly installed at the center of the vertical surface of the outer wall of the rotating wheel 45 at one end near the center of the turntable 7. The inner wall of the sliding ring 52 penetrates and is slidably installed on the outer wall surface of the reciprocating screw 51. The top of the fanning plate 53 is slidably installed at the bottom edge of the device body 1 through a spring, and a sliding groove is provided on the outer wall of the fanning plate 53. The vertical surface of the fanning plate 53 on one side near the center of the cooling component 42 is fixedly connected to the vertical surface of the outer wall of the sliding ring 52. Through the above cooperation, the gas circulation rate around the device body 1 is accelerated to drive the salt generated when the sweat evaporates, and at the same time, the diffusion rate of the cold air of the cooling component 42 is accelerated to avoid the erosion of the inside of the device body 1 during the natural evaporation of sweat, increasing the possibility of its mildew.

[0039] The circulation device 5 also includes a rotating rod 54, a fixed ring 55, a telescopic plate 56 and a plurality of activated carbon plates 57. The rotating rod 54 is rotatably mounted on the vertical surface of the inner wall of the fanning plate 53 at one end away from the center of the cooling assembly 42, and a spiral groove is opened on the outer wall of the rotating rod 54. The inner wall of the fixed ring 55 penetrates and is slidably mounted on the surface of the spiral groove on the outer wall of the rotating rod 54. The bottom of the telescopic plate 56 is fixedly mounted on the top of the telescopic assembly 8, and the telescopic end of the telescopic plate 56 is fixedly mounted on the bottom of the outer wall of the fixed ring 55. A plurality of activated carbon plates 57 are equidistant and fixedly mounted on the outer wall surface of the rotating rod 54. Through the above cooperation, the activated carbon plates 57 are prompted to absorb the harmful odor of the leather emitted by the device body 1 due to sunlight in summer, so as to prevent children from inhaling harmful odors and causing health effects, thereby providing a safe riding environment for children.

[0040] The circulation device 5 also includes a limit plate 58 and a plurality of L-shaped plates 59. The limit plate 58 is rotatably installed on the vertical surface of the outer wall of the rotating rod 54 away from the center side of the cooling component 42 through a torsion spring. The plurality of L-shaped plates 59 are equidistantly and fixedly installed on the outer wall surface of the limit plate 58. The L-shaped plate 59 is located on the movement trajectory of the edge of the activated carbon plate 57 close to the center side of the cooling component 42, and the L-shaped plate 59 has toughness. Through the above coordination, the activated carbon plate 57 is prompted to use vibration force to make the absorption process of harmful odors by the activated carbon inside itself more uniform, thereby avoiding excessive saturation of absorption of individual activated carbon plates 57, resulting in secondary overflow of harmful odors, and to a certain extent extending the replacement cycle of the activated carbon plate 57.

[0041] When in use, the rotating wheel 45 drives the reciprocating screw rod 51 to rotate when the rotating wheel 45 rotates. When the reciprocating screw rod 51 rotates, the reciprocating spiral groove on its outer wall restricts the sliding ring 52. At the same time, the limit block inside the sliding ring 52 constantly contacts the spiral groove on the outer wall of the reciprocating screw rod 51, so that the sliding ring 52 can slide back and forth along its surface when the reciprocating screw rod 51 rotates. When the sliding ring 52 slides, it pushes the fan plate 53 to slide synchronously along the bottom of the device body 1. When the fan plate 53 slides back and forth, it fans the bottom of the device body 1 and the surrounding air. Through the above cooperation, the gas circulation rate around the device body 1 is accelerated to drive the salt generated when the sweat evaporates, and at the same time, the diffusion rate of the cold air of the cooling component 42 is accelerated, so as to avoid the corrosion of the inside of the device body 1 during the natural volatilization of sweat and increase the possibility of its mildew; when the fan plate 53 slides back and forth, it drives the rotating rod 54 to move synchronously. When the rotating rod 54 slides back and forth, the non-self-locking spiral groove on its outer wall contacts the block on the inner wall of the fixing ring 55 to drive the rotating rod 54 generates a rotating force and starts to rotate, and the telescopic plate 56 limits the fixed ring 55, and at the same time, the rotating rod 54 drives the activated carbon plate 57 to rotate. Through the above cooperation, the activated carbon plate 57 is prompted to absorb the harmful odor emitted by the leather of the device body 1 due to the summer sunlight, so as to prevent children from inhaling harmful odors and causing health effects, and provide a safe riding environment for children; when the rotating rod 54 rotates, the limiting plate 58 remains stationary. At this time, the activated carbon plate 57 rotates and hits the L-shaped plate 59. The L-shaped plate 59 forms a resistance to the activated carbon plate 57 through the torsion force of the torsion spring between the limiting plate 58 and the rotating rod 54, thereby increasing the impact force of the activated carbon plate 57 and causing the activated carbon plate 57 to vibrate. Through the above cooperation, the activated carbon plate 57 is prompted to use the vibration force to make the absorption process of the harmful odor by the activated carbon inside itself more uniform, so as to avoid the excessive saturation of the absorption of the harmful odor by individual activated carbon plates 57, and to a certain extent, the replacement cycle of the activated carbon plate 57 is extended.
