Especially in cold winter or hot summer, if the temperature of seat can be adjusted according to user's demand, avoid the user to be in for a long time under the uncomfortable temperature and produce tired sense, can more accord with humanized design theory.

To this end, the present embodiment provides a seat, which includes a seat body and a seat temperature adjusting device provided on the seat body. The traditional seat temperature adjusting mode is divided into a cooling part and a heating part, and the resistance wire and the fan are used for cooling and heating adjustment, but the traditional seat temperature adjusting mode is not ideal in structural arrangement and using effect.

In view of the above problems, the present embodiment provides a seat temperature adjustment device, which can be applied to various fields such as public service places, offices, and homes, especially to an automotive interior system. The present embodiment is exemplified by the application of the seat temperature adjusting apparatus to a vehicle seat.

To increase the soft comfort of the seat, the seat assembly 1 is also provided with padding 12. The inner container block is embedded in the filler 12, so that the filler 12 and the liquid block 11 form a whole. The shape of the liquid slug 11 depends on the design of the seat and, in this embodiment, with continued reference to fig. 1-3, the shape and size of the liquid slug 11 depends on the design of the seat back 3 and seat cushion 4. In addition, the inner container blocks can be designed into different shapes according to the arrangement position and the modeling design of the filler 12, as shown in fig. 2, the inner container blocks on the chair back 3 are circular, and a plurality of circular inner container blocks are embedded in the filler 12 of the chair back 3; as shown in fig. 3, the inner bag blocks on the seat cushion 4 are square, and a plurality of square inner bag blocks are embedded in the filler 12 on the seat cushion 4.
