The purpose of this utility model is achieved by following technical proposals.

The utility model includes plug, temperature control switch, control box, metal buttocks model, temperature sense probe, aluminium foil heating The structures such as piece, outer layer insulation material, steam generator, safety valve, steam output switch, air pressure valve.

Described plug is connected with one end of aluminium foil heating plate, and being inserted on socket can power to aluminium foil heating plate.

Described temperature control switch is connected with temperature sense probe and aluminium foil heating plate, is realized by adjusting temperature control switch to aluminium The switch of paper tinsel heating plate and to temperature adjustment.

Described steam generator is connected by steam output switch with buttocks model, and steam is adjusted by baroswitch Air pressure in generator, so as to which caused steam is transported in the buttocks model of uniform small pores by conduit, simulate human body Humidity.

Described temperature sense probe is placed between metal buttocks model and aluminium foil heating plate to sense Current Temperatures, from And ensure the normal work of temperature control switch.

Described aluminium foil heating plate one side band glue, is close on metal buttocks model, the heating for metal buttocks model.

Shown outer layer insulation material is coated on outside metal buttocks model, plays certain insulation effect.

The utility model has advantages below compared with existing test device：Simulate the simulation human buttock of human buttock Moulding, surface temperature and body weight, can be tested, safety simple to operate with the thermal comfort of unlike material office chair, and increase is real The accuracy and science tested.
