Example one

As shown in fig. 1 and 2, an embodiment of the present invention provides a ventilation liner mechanism, including: the mattress comprises a bottom pad 100, a flexible inner pad 200 and a surface pad 300, wherein the flexible inner pad 200 is arranged between the bottom pad 100 and the surface pad 300;

the base pad 100 is provided with a first vent hole 101, the flexible inner liner 200 is provided with a second vent hole 201, the surface layer pad 300 is provided with a third vent hole 301, and the first vent hole 101, the second vent hole 201 and the third vent hole 301 are sequentially in fluid communication.

When the ventilation liner mechanism is reclined, the flexible inner liner 200 is squeezed between the base mat 100 and the skin mat 300. The gas in the second vent hole 201 is pushed into the first vent hole 101 and the third vent hole 301; during rebound of the flexible inner liner 200, the gas in the first vent hole 101 and the third vent hole 301 flows into the second vent hole 201. Thus, the ventilation performance of the ventilation liner mechanism can be enhanced in the process of the flexible inner liner 200 being compressed and rebounded, thereby avoiding the problem of poor riding comfort due to sultry of the skin contacting the skin sheet 300.

In the embodiment of the present invention, the aperture of the first ventilation hole 101 is smaller than the aperture of the second ventilation hole 201.

Specifically, when the flexible inner liner 200 is compressed, the inner space of the second vent hole 201 is reduced, and a part of the gas in the second vent hole 201 may be pushed into the first vent hole 101. Since the first vent hole 101 has a small aperture, the external air can flow into the first vent hole 101 at a fast flow rate, and when the flexible inner cushion 200 is compressed, only a small amount of air is discharged through the first vent hole 101, and another part of the air in the second vent hole 201 is blown onto the body of the occupant through the third vent hole 301.

Further, the aperture of the second ventilation hole 201 is larger than that of the third ventilation hole 301.

Specifically, when flexible inner liner 200 is compressed, the gas in second ventilation hole 201 is extruded to third ventilation hole 301 in, because the aperture of third ventilation hole 301 is less, the gas velocity of flow that gets into third ventilation hole 301 is very fast, and then makes gas blow to the passenger with higher speed to improve ventilation cooling effect.

Further, the base mat 100 is provided with a groove 110, the flexible inner liner 200 is installed in the groove 110, and the surface mat 300 covers the groove 110.

Specifically, the surface layer cushion 300 covers the opening of the groove 110, and an inner cavity for accommodating the flexible inner pad 200 is formed between the base cushion 100 and the surface layer cushion 300. The flexible inner cushion 200 is bent and the child can sit on the ventilation cushion mechanism and the back of the child can lean on the ventilation cushion mechanism.

It should be noted that the flexible inner liner 200 can be selected from PU, EPS, EPP, EPO, or EPE. The flexible inner liner 200 is soft in texture, can be compressed when squeezed, and can rebound when pressure is reduced.

Example two

As shown in fig. 1, fig. 2 and fig. 3, the embodiment of the present invention provides a seat, including: the seat body 400 and the ventilation liner mechanism provided in the first embodiment, the base pad 100 is mounted on the seat body 400.

Specifically, ventilation liner mechanism installs in the district of taking of seat body 400, the embodiment of the utility model provides a seat possesses ventilation liner mechanism's beneficial effect, no longer gives unnecessary details here.

In the embodiment of the present invention, the seat portion of the seat body 400 is provided with a fourth ventilation hole 401, and the fourth ventilation hole 401 is in fluid communication with the first ventilation hole 101.

The plurality of fourth ventilation holes 401 are formed in the backrest of the seat body 400, the fourth ventilation holes 401 are arranged at intervals, external air can flow into the first ventilation hole 101 through the fourth ventilation holes 401, and humid hot gas on the surface of the skin can sequentially flow through the third ventilation holes 301, the second ventilation holes 201, the first ventilation hole 101 and the fourth ventilation holes 401 to be discharged.

Further, the seat body 400 is mounted with a fan 500, and the fan 500 is in fluid communication with the first vent hole 101.

In this embodiment, the damp and hot air on the back of the passenger can flow through the third vent hole 301, the second vent hole 201, the first vent hole 101 and the fourth vent hole 401 in sequence along with the air flow of the air conditioner in the vehicle, and the fan 500 is additionally arranged to provide airflow power, so that the ventilation efficiency is improved.

Further, a seat back outer shell 600 is installed on a side of the seat body 400 facing away from the bottom cushion 100, and the seat back outer shell 600 has a decorative effect on the back of the seat body 400.

Further, the seat back housing 600 is provided with a fifth vent hole 601, and the fifth vent hole 601 is in fluid communication with the fourth vent hole 401.

The third ventilation hole 301, the second ventilation hole 201, the first ventilation hole 101, the fourth ventilation hole 401 and the fifth ventilation hole 601 are sequentially in fluid communication, and the damp and hot air on the back of the child is taken away in a ventilation mode, so that the riding comfort is improved.

As shown in fig. 1, the seat back of the seat body 400 is provided with a first side guard portion 410 and a second side guard portion 420, and the seating area of the seat body 400 is located between the first side guard portion 410 and the second side guard portion 420.

Specifically, the child is seated in the seating area, the first side guard 410 is secured to the right side of the child, and the second side guard 420 is secured to the left side of the child, so that the child can be restrained in the seating area.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
