wherein, an air inlet 21 is provided on the sidewall of the cold/heat source accommodating bag 20, a plurality of micro fans 30 (preferably 5V dc fans for the convenience of the cushion in use at the right time) are embedded on the inner wall, meanwhile, a plurality of air duct hoses 40 communicated with the inner space of the cold/heat source accommodating bag 20 through the micro fans 30 are embedded in the cushion body 10, and correspondingly, a plurality of air outlet holes 11 communicated with the corresponding air duct hoses 40 are provided on the surface of the cushion body 10 and along the arrangement path of the air duct hoses 40.

Therefore, when the ventilating seat cushion is actually used, the seat cushion can be laid on a carrying tool such as a cart seat or a safety seat, the cold/heat source accommodating bag 20 is suspended at the foot end side of the seat, then frozen mineral water and the like are used as a cold source to be placed in the cold/heat source accommodating bag 20, namely, after the micro fan 30 is started, air in the external environment is firstly sucked into the cold/heat source accommodating bag 20 through the air inlet hole 21 and is subjected to heat exchange with the cold source to cool the air, then the cooled air is pushed along the air duct hose 40 by the micro fan 30 and finally is discharged from the surface side of the seat cushion body 10 through the air outlet hole 11, so that the back, the hip and other parts of an infant can be effectively cooled, skin diseases such as miliaria, eczema and the like caused by damp heat are avoided, and the riding comfort of the seat is enhanced; the whole ventilating seat cushion can adopt personal articles such as frozen mineral water in daily life as a cold source, and the use cost of the seat cushion can be effectively reduced. Of course, in the case where the ambient temperature is low, such as in winter, a water bottle or the like, such as water filled with hot water, may be employed as the heat source medium, thereby achieving the heating and ventilating function of the seat cushion.

In order to enhance the practical performance of the whole seat cushion, especially to improve the convenience of the operation and control of the seat cushion, the seat cushion of this embodiment further includes a power supply interface (not shown in the figure, which may be a USB interface or a DC interface, etc. according to the actual situation, so that the user can use a device such as a mobile phone charger, etc. as a power supply) and a control switch 52 embedded in the seat cushion body 10 to sequentially connect the power supply interface, the control switch 52 and the micro fans 30, wherein, in order to avoid that the whole seat cushion cannot perform the cooling or heating function due to the failure of one of the micro fans 30, the micro fans 30 of this embodiment are connected in parallel or in a mixed manner.

In order to prevent the air outlet 11 from being blocked due to the contact pressure of the infant body during the actual use of the seat cushion, thereby affecting the air outlet effect, as shown in fig. 4, a plurality of massage protrusions 12 are disposed on the surface of the seat cushion body 10, and the air outlet 11 is distributed in the area enclosed by the plurality of massage protrusions 12. Therefore, the height difference formed by the massage bulges 12 and the air outlet holes 11 on the surface of the seat cushion body 10 can effectively prevent the air outlet holes 11 from being blocked when the seat cushion is taken, and the air outlet effect of the seat cushion is ensured. Of course, as one preferred scheme, while having the massage protrusions 12, each of the air outlets 11 may also have a hollow protrusion 13 (as shown in fig. 5) having a top surface flush with the top surface of the massage protrusion 12, and the peripheral surface of each of the hollow protrusions 13 is provided with an air outlet micro-hole 14 for communicating with the corresponding air duct hose 40 through the air outlet 11, so as to ensure the air outlet effect of the seat cushion.

Therefore, the air quantity of the individual air outlet holes 11 is avoided as much as possible by utilizing the aperture difference between the air outlet holes 11 at different positions, so that the comfortableness of the seat cushion is improved by enhancing the uniformity of the air outlet of the seat cushion.

In order to prevent the air duct hose 40 from being squeezed to affect the air transportation when the seat cushion body 10 is in use, as a preferred scheme, the seat cushion body 10 of the present embodiment mainly comprises a peripheral fabric layer e and a plurality of flexible supporting frameworks f sewn in the peripheral fabric layer e, and the air duct hose 40 is disposed in the flexible supporting frameworks f. Therefore, the flexible supporting framework f can be used for providing structural protection for the air duct hose 40, and the air duct hose 40 is prevented from being subjected to excessive extrusion force, so that structural conditions are created for ensuring smooth air conveying; in practice, the flexible supporting skeleton f of the present embodiment may be made of a material such as a thickened sponge layer or a flexible plastic material having a hardness slightly larger than that of the air duct hose 40, in consideration of the condition that the infant is light in weight.

In addition, in order to optimize the structure of the whole ventilation seat cushion to the maximum extent, the cold/heat source accommodating bag 20 of the present embodiment includes a bag body portion 22 sewn to the bottom end side of the seat cushion body 10 and having a port, a bag cover portion 23 sewn to the port edge of the bag body portion 22 and having one side edge integrally connected to the bag body portion 22 through a hook and loop fastener or a zipper (not shown), a supporting plate portion 24 disposed on the inner wall of one side of the bag body portion 22 for positioning and assembling the micro fan 30, and a heat insulating layer portion 25 (which may be made of an aluminum foil material according to actual conditions) disposed on the inner wall of the bag cover portion 23 and on the other inner walls of the bag body portion 22, wherein the air inlet holes 21 are opened on the bottom side wall of the bag body portion 22 and/or on the side wall opposite to the supporting plate portion 24 and distributed through the heat insulating layer portion 25. Therefore, a cavity structure for placing a cold and heat source can be formed by the bag cover part 23 and the bag body part 22, and the external air can be ensured to contact and exchange heat with the cold and heat source to the maximum extent by utilizing the corresponding relation of the directions between the air inlet holes 21 and the micro-fans 30, so that conditions are created for improving the heat exchange efficiency; in addition, the heat insulation layer 25 can reduce the loss of cold or heat to the maximum extent, thereby improving the utilization rate of the cold or heat.
