The ventilation system generally comprises an air suction mode and an air blowing mode, the air suction mode is relatively soft in wind force, the air blowing mode is relatively large in wind force, and children are easy to catch a cold. The application provides a child seat 100, including but not limited to the application on vehicles such as car, train, steamer and aircraft, has good ventilation heat dissipation function, is favorable to improving the comfort level that children take, is favorable to children's physical and mental health.

Referring to fig. 1 to 3, the child seat 100 provided in the present embodiment includes a seat body 110, a fan 150, and a ventilation pad 140, wherein the seat body 110 includes a seat front 101 and a seat back 103 disposed oppositely, the ventilation pad 140 is disposed on the seat front 101, and the fan 150 is mounted on the seat body 110. A siphon air channel 111 is formed between the seat front 101 and the ventilation pad 140, an air inlet 121 is formed on the seat body 110, an air outlet 165 is formed on the seat back 103, the air inlet 121 is communicated with the siphon air channel 111, the siphon air channel 111 is communicated with the fan 150, and the fan 150 is used for discharging air flow passing through the siphon air channel 111 from the air outlet 165. The fan 150 adopts an air suction mode, so that a large amount of air enters the siphon air channel 111, the air flow is increased, the ventilation and heat dissipation functions of the child seat 100 are realized, and the use comfort of the child seat 100 is greatly improved.

Referring to fig. 4 and 5, a plurality of first ventilation holes 141 are further formed in the ventilation pad 140, and the plurality of first ventilation holes 141 are communicated with the siphon air channel 111. After the fan 150 starts the air suction mode, the air not only enters the siphon air channel 111 from the air inlet 121 in a large amount, but also enters the siphon air channel 111 from the first vent hole 141, so that the air inlet amount is increased, the ventilation area is enlarged, and the ventilation and heat dissipation effects are enhanced. It is understood that the seat body 110 includes a seat part 120 and a backrest part 130 connected to each other, the seat part 120 for supporting the buttocks of the user, and the backrest part 130 for supporting the waist and the back of the user. In this embodiment, the ventilation pad 140 is laid on the front surface 101 of the seat, and partially or completely covers the seat part 120 and the backrest part 130 together, and the first ventilation holes 141 are arranged at intervals on the ventilation pad 140, that is, the first ventilation holes 141 are arranged on the ventilation pad 140 corresponding to the seat part 120 and the backrest part 130, so that air flows pass through the seat part 120 and the backrest part 130, the ventilation area is large, the ventilation effect is good, and the heat dissipation efficiency can be greatly improved after the fan 150 is turned on.

Alternatively, the shape of the first vent holes 141 may be circular, square, triangular, oval or any other shape, and the first vent holes 141 may be arranged in a rectangular array or in a circular array on the vent pad 140; the distribution may be regular and uniform, or random, and is not limited herein. In this embodiment, in order to achieve a better siphon effect and facilitate production, the first ventilation hole 141 on the ventilation pad 140 is a circular hole, and the diameter of the circular hole is smaller than or equal to 3mm, such as 1mm, 1.5mm, 2mm or 2.5 mm. The sizes of the apertures of all the first ventilation holes 141 may be equal or different, and are not particularly limited herein.

The ventilation pad 140 is provided with a plurality of bumps 143, the bumps 143 are arranged at intervals, and one ends of the bumps 143 far away from the ventilation pad 140 are arranged on the seat front 101, so that the seat front 101 and the ventilation pad 140 are arranged at intervals to form the siphon air duct 111.
