Description

Technical Field

[0001] This utility model relates to the field of child car seat technology, and in particular to a ventilated child car seat. Background Technology

[0002] Children's bodies are more vulnerable, and they are easily seriously injured in the event of a vehicle collision or sudden braking. Child seats are designed according to children's physical characteristics, providing effective restraint and cushioning to reduce the risk of injury in accidents. They can properly secure a child's body position, preventing them from colliding with hard objects inside the vehicle or being ejected from the vehicle. Children of different ages have different levels of physical development, and child seats are available in various types and sizes to meet the needs of children of different ages.

[0003] Some child car seats may have poorly breathable surface materials, such as some artificial leather or plastic. These materials can hinder airflow when in contact with a child's body, causing heat and moisture to accumulate, resulting in a stuffy feeling. This stuffiness is especially noticeable in hot weather or during long periods of sitting. Therefore, most child car seats are designed with ventilation systems. However, since children's bodies are weaker than adults, prolonged exposure to ventilation systems can cause their backs to become too cold, leading to chills. This is especially true in air-conditioned environments, where the combined effect of ventilation makes children more susceptible to feeling cold. Excessive ventilation can also affect local blood circulation in children. Prolonged exposure to cold air blowing directly on the back can cause muscle tension and vasoconstriction, thus affecting normal metabolism and physiological functions. Utility Model Content

[0004] The purpose of this invention is to provide a ventilated child seat to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ventilated child seat, comprising:

[0007] A seat body, wherein a backrest is provided on the seat body;

[0008] The air duct is installed in the inner cavity of the seat body, and the opening of the air duct is provided with several swingable blades;

[0009] The mounting slot is set on the air duct, and a moving block that drives the blade to swing is slidably arranged in the mounting slot.

[0010] Preferably, the duct is connected to a fan, and the opening of the duct is gradually enlarged.

[0011] Preferably, grooves are symmetrically arranged on the inner wall of the duct opening, and sliding blocks are slidably arranged in each groove, with several connecting shafts arranged on each sliding block.

[0012] Preferably, the opening of the duct is also provided with several support rods, all of which are rotatably connected to the blades.

[0013] Preferably, each blade has a symmetrically formed connecting groove, and the connecting groove is slidably connected to the connecting shaft.

[0014] Preferably, a fixing block is fixedly installed on the air duct, and a drive shaft is rotatably installed through the fixing block.

[0015] Preferably, the drive shaft is externally connected to an external drive, and a crank is fixedly mounted on the drive shaft.

[0016] Preferably, a fixed shaft is provided on the crank, offset from the axis of the drive shaft.

[0017] Preferably, the groove above the air duct and the mounting groove at the top of the air duct are interconnected, and the movable block in the mounting groove is fixedly connected to the sliding block in the groove.

[0018] Preferably, the movable block is provided with a sliding groove, which is slidably connected to the outer surface of the fixed shaft.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] By combining air ducts with oscillating blades, the ventilation of the seat can be significantly improved, especially in hot summer months, providing children with a cooler and more comfortable sitting experience. Avoiding prolonged exposure of the same area of ​​the back to excessive cooling can cause discomfort or pain. The oscillating blades ensure even airflow distribution across the back, preventing localized overcooling and thus improving overall comfort.

[0021] The sliding block is positioned within the mounting slot, and its movement causes the blades to oscillate. This oscillation allows air to be distributed more evenly throughout the seat, improving ventilation efficiency. The oscillation also prevents airflow from being directed at the same spot on the back for extended periods, reducing discomfort and improving child comfort. Compared to fixed-direction airflow, oscillating blades generate less noise, providing a quieter riding environment for children.

[0022] By adjusting the rotation speed of the drive shaft, the oscillation speed of the blades can be changed. This adjustable blade oscillation speed allows the child seat to be flexibly adjusted according to different environments and needs. For example, in hot summers or enclosed spaces, the blade oscillation speed can be increased to enhance ventilation; while in cool spring and autumn seasons or well-ventilated environments, the blade oscillation speed can be slowed down to avoid over-ventilation.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0032] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0033] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0034] Please see Figures 1-5 A ventilated child seat includes: a seat body 1, which is designed in an ergonomic shape for children and equipped with non-slip foot pads on the bottom to ensure the seat is stable and does not easily slide. The edges of the seat are rounded to prevent injury to children during use. The seat body 1 has a backrest 2, the angle of which is freely adjustable to accommodate the needs of children of different ages. Parents can easily adjust the backrest 2 angle using a simple buckle or knob design to provide optimal sitting posture support for the child.

[0035] A ventilated child seat further includes: an air duct 3, which is disposed within the inner cavity of the seat body 1. The air duct 3 is cleverly integrated into the inner cavity of the seat body 1, without occupying external space, while ensuring smooth airflow. Several oscillating blades 8 are provided at the opening of the air duct 3. The combination of the air duct 3 and the oscillating blades 8 significantly improves the ventilation effect of the seat, especially in hot summers, providing children with a cooler and more comfortable sitting experience. Furthermore, when airflow is directed at the same part of the back for a prolonged period, it may cause that area to become excessively cooled, even causing discomfort or pain. The oscillating blades 8 ensure that the airflow is evenly distributed on the back, avoiding localized excessive cooling, thereby improving overall comfort.

[0036] A ventilated child seat further includes: a mounting groove 10, which is disposed on an air duct 3. A movable block 11, capable of oscillating blades 8, is slidably disposed within the mounting groove 10. The movable block 11, slidably disposed within the mounting groove 10, can oscillate the blades 8 by moving. Through the oscillation of the blades 8, air can be more evenly distributed throughout the seat, thereby improving ventilation efficiency. The oscillation of the blades 8 prevents airflow from being directed at the same area of ​​the back for extended periods, reducing discomfort and improving the child's riding comfort. Compared to a fixed-direction airflow, the oscillating blades 8 generate less noise when creating airflow, providing a quieter riding environment for the child.

[0037] The air duct 3 is connected to an external fan, and its opening gradually widens. As the core component of the ventilation system, air duct 3 is responsible for delivering air to all parts of the seat. The airflow generated by the fan propels the air through the interior of air duct 3, thus achieving ventilation. The gradually widening opening of air duct 3 helps reduce airflow resistance at the opening, improving airflow efficiency. Simultaneously, the gradually widening opening allows for a more even distribution of airflow across the seat, further enhancing ventilation.

[0038] Furthermore, grooves 4 are symmetrically arranged on the inner wall of the opening of the air duct 3, and sliding blocks 5 are slidably arranged in each groove 4. Several connecting shafts 6 are arranged on each sliding block 5. Several support rods 7 are also provided at the opening of the air duct 3, and each support rod 7 is rotatably connected to the blades 8. Connecting grooves 9 are symmetrically opened on each blade 8, and the connecting grooves 9 are slidably connected to the connecting shafts 6. When the fan starts, the generated airflow pushes the air inside the air duct 3. As the airflow flows, when the sliding blocks 5 slide in the grooves 4, they drive the connecting shafts 6 to move. The movement of the connecting shafts 6 pushes the blades 8 through the connecting grooves 9, causing the blades 8 to rotate on the support rods 7. The rotation of the blades 8 changes the direction and speed of the airflow, allowing the air to be more evenly distributed throughout the seat.

[0039] It should be noted that the length of the connecting groove 9 is greater than the diameter of the connecting shaft 6, ensuring that the blade 8 will not be subject to resistance during rotation, improving the flexibility of the blade 8 rotation, helping to ensure smooth airflow, improving ventilation efficiency, and reducing noise caused by resistance.

[0040] Furthermore, a fixing block 13 is fixedly installed on the duct 3, and a drive shaft 14 is rotatably mounted through the fixing block 13. An external drive is connected to the drive shaft 14, and a crank 15 is fixedly installed on the drive shaft 14. A fixed shaft 16 is mounted on the crank 15, offset from the axis of the drive shaft 14. The groove 4 above the duct 3 and the mounting groove 10 at the top of the duct 3 penetrate each other, and the moving block 11 in the mounting groove 10 is fixedly connected to the sliding block 5 in the groove 4. A sliding groove 12 is formed on the moving block 11, and the sliding groove 12 is slidably connected to the outer surface of the fixed shaft 16.

[0041] The rotation of the drive shaft 14 causes the crank 15 at the bottom of the drive shaft 14 to rotate synchronously. When the crank 15 rotates, the fixed shaft 16 slides in the groove 12 of the moving block 11 and drives the moving block 11 to slide back and forth. This causes the sliding block 5 in the groove 4 driven by the moving block 11 to move synchronously, causing the connecting shaft 6 to slide in the connecting groove 9 of the blade 8 and drive the blade 8 to swing back and forth. The swinging of the blade 8 can effectively stir the surrounding air and increase the air circulation. A well-ventilated child seat can improve the comfort of children and reduce the stuffiness and discomfort caused by sitting for a long time.

[0042] It is worth mentioning that the oscillation speed of the blades 8 can be changed by adjusting the rotation speed of the drive shaft 14. This function of adjusting the oscillation speed of the blades 8 allows the child seat to be flexibly adjusted according to different environments and needs. For example, in hot summers or enclosed spaces, the oscillation speed of the blades 8 can be increased to enhance ventilation; while in cool spring and autumn seasons or well-ventilated environments, the oscillation speed of the blades 8 can be slowed down to avoid over-ventilation.
