Multiple second suction cups 201 are connected to the ends, and the upper ends of the first suction cup 2 and the second suction cup 201 are fixedly connected to the ventilation pipe 202, and the ventilation pipe 202 is provided with an air cavity 203. The second support tube 206 and the first support tube 205 are fixedly connected to the outer sides of the ventilation pipe 202 on the first suction cup 2 and the ventilation pipe 202 on the second suction cup 201 respectively, and the upper ends of the first support tube 205 and the second support tube 206 pass through the inner aluminum foil insulation layer 102 and extend to between the outer aluminum foil insulation layer 101 and the inner aluminum foil insulation layer 102.

[0024] Furthermore, the first annular metal wire 103 and the second annular metal wire 104 are fixedly connected by a plurality of connecting metal wires 105, and the outer aluminum foil insulation layer 101 together with the inner aluminum foil insulation layer 102 are stretched open by the first annular metal wire 103 and the second annular metal wire 104 and the connecting metal wires 105 therebetween. When placed on the windshield of a vehicle, the inner end surface of the heat insulation cover 1 is supported by the first support tube 205, so that the inner aluminum foil insulation layer 102 is separated from the windshield to form an air layer, thereby improving the insulation efficiency. By pressing the edge of the outer aluminum foil insulation layer 101 and bending it through the connecting metal wires 105, the edge of the inner aluminum foil insulation layer 102 is made to fit closely to the automobile glass.

[0025] Furthermore, a vent 204 is provided in the middle of the first suction cup 2 and the second suction cup 201 , and the vent 204 is communicated with the air cavity 203 inside the ventilation tube 202 .

[0026] Furthermore, the ventilation pipe 202 on the first suction cup 2 and the ventilation pipe 202 on the second suction cup 201 respectively pass through the second support pipe 206 and the first support pipe 205 to extend to the upper end and communicate with each other through the branch communication pipe 207 .

[0027] Furthermore, the air vent 202 on the second suction cup 201 is connected between the outer aluminum foil insulation layer 101 and the inner aluminum foil insulation layer 102 via an annular connecting pipe 208, and the branch connecting pipe 207 and the annular connecting pipe 208 connect the air vent 202 on all the first suction cups 2 and the air vent 202 on the second suction cups 201, so that gas exchange and balance can be easily performed on each suction cup, ensuring that each suction cup can be evenly stressed and provide stable adsorption force.

[0028] Furthermore, the upper ends of the ventilation pipes 202 on the two second suction cups 201 on both sides of the middle of the lower end surface of the inner aluminum foil insulation layer 102 pass through the outer aluminum foil insulation layer 101 and extend to the upper end and are connected with a round cap 3.

When it is necessary to remove the heat insulation cover 1, the blocking cone 301 is pulled out to connect the entire connecting pipe system with the external air, thereby releasing the adsorption force of the first suction cup 2 and the second suction cup 201, thereby facilitating the separation of the heat insulation cover 1 from the windshield.

[0030] Working principle: When in use, the outer aluminum foil insulation layer 101 together with the inner aluminum foil insulation layer 102 is stretched open by the first annular metal wire 103, the second annular metal wire 104 and the connecting metal wire 105 therebetween. When placed on the windshield of a vehicle, the inner end face of the heat insulation cover 1 is supported by the first support tube 205, so that the inner aluminum foil insulation layer 102 is separated from the windshield to form an air layer, thereby improving the insulation efficiency. By pressing the edge of the outer aluminum foil insulation layer 101 and bending the connecting metal wire 105, the edge of the inner aluminum foil insulation layer 102 is closely attached to the automobile glass. By pressing the outer side of the outer aluminum foil insulation layer 101, the gas in the first suction cup 2 and the second suction cup 201 is discharged, and a negative pressure is formed inside the suction cup. The air pipes 202 on all the first suction cups 2 and the air pipes 202 on the second suction cups 201 are connected through the branch connecting pipe 207 and the annular connecting pipe 208, so that the gas exchange and balance of each suction cup can be conveniently carried out, ensuring that each suction cup can be evenly stressed and providing a stable adsorption force. The lower end of the circular cap 3 is fixedly connected with a blocking cone 301, and the blocking cone 301 is inserted into the air cavity 203 inside the upper end of the air pipe 202 for blocking. When it is necessary to remove the heat insulation cover 1, the blocking cone 301 is pulled out to connect the entire connecting pipe system with the external air, thereby releasing the adsorption force of the first suction cup 2 and the second suction cup 201, and facilitating the separation of the heat insulation cover 1 from the windshield.
