Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] As attached Figure 1 Appendix Figure 2 and attached Figure 3 As shown, a bag-type ventilated thermoelectric air-conditioned seat includes a thermoelectric cooling module 1, a fan 4, an air guide bag 15, a dual ventilation duct 16, and a connector 11. The thermoelectric cooling module 1 is used to cool or heat the air. The thermoelectric cooling module 1 includes a thermoelectric device 3 and a housing. The thermoelectric device 3 is installed inside the housing. The housing is connected to the outlet of the fan 4 through an air duct connecting pipe 5. The housing and the air duct connecting pipe 5 are sealed together. Sealing straps 6 are installed at both ends of the air duct connecting pipe 5. A heat-insulating adhesive surface 13 is installed between the outer side of the thermoelectric device 3 and the housing. Heat-insulating foam 14 is inserted inside the thermoelectric device 3 to improve energy efficiency and prevent condensation.

[0030] The housing includes an upper housing 8 and a lower housing 9, which are fixedly connected by multiple sets of bolts 7. A double exhaust port 2 is installed on one side of the upper housing 8 to exhaust the air after heat exchange.

[0031] As attached Figure 4 and attached Figure 5 As shown, the air guide bag 15 is arranged in the back of the seat and inside the seat cushion, and is connected to the outlet of the fan 4 through the dual ventilation channels 16 to achieve uniform airflow distribution.

[0032] As attached Figure 1 and attached Figure 3 As shown, the connector 11 is connected to an external control unit and is used to monitor the operation of the thermoelectric cooling module 1 and the fan 4. Multiple sets of connecting wires 10 are connected between the connector 11, the fan 4, and the thermoelectric device 3. The multiple sets of connecting wires 10 in the same direction are covered with sleeves 12 to ensure the safety and cleanliness of the wiring. The thermoelectric device 3 is a semiconductor thermoelectric element that achieves cooling or heating based on the Peltier effect. It has the advantages of fast response, no vibration, and long life.

[0033] The specific usage method is as follows:

[0034] After the system is powered on, the external control unit starts the fan 4 and the thermoelectric device 3 via connector 11. The fan 4 sends air into the thermoelectric cooling module 1, where it is cooled or heated, and then transported to the air duct 15 through the dual ventilation channels 16, finally exiting through small holes on the seat surface to achieve heat exchange with the occupant. Users can adjust the airflow and temperature settings through the control unit to obtain the best comfort experience.
