For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1As shown, the utility model discloses a ventilation bag for facilitating replacement of activated carbon, comprising a ventilation bag body 1 arranged on a car seat 20, one end of the ventilation bag body 1 is provided with a ventilation connection port 2, and the ventilation connection port 2 is connected to a fan. The fan can convey wind into the ventilation bag body 1, and then blow it out through the ventilation bag body 1, forming an air circulation.

[0031] like Figure 2 , Figure 3 As shown, the ventilation bag body 1 includes a honeycomb air permeable layer 3, an elastic support layer 4, an activated carbon layer 5, an elastic air inlet layer 6 and a bottom support layer 7 in sequence from the side close to the human body. Figure 4 , Figure 5 As shown, the honeycomb breathable layer 3 includes a plurality of hexagonal holes 8 connected to each other, and a support column 9 is arranged at the center of the hexagonal hole 8, and the support column 9 is connected to the six sides of the hexagonal hole 8 through a connecting piece 10. The honeycomb breathable layer 3 is made of latex, and the hexagonal holes 8 of the honeycomb breathable layer 3 are arranged perpendicular to the elastic support layer 4. The six sides of the hexagonal holes 8 are vertical on the ventilation bag body 1, and the support columns 9 and the connecting piece 10 cooperate with the six sides of the hexagonal holes 8 to support the human body. When the human body sits or leans on the seat 20, the honeycomb breathable layer 3 of the ventilation bag body 1 between the human body and the seat 20 is not easy to be completely flattened, and the wind can be blown out from the hexagonal holes 8. The use of latex and the human body pressing on it can improve the comfort of sitting.

[0032] like Figure 6 As shown, the elastic support layer 4 includes a rubber pad 11 with a plurality of air holes 12, and a support spring 13 is arranged in the air holes 12 of the rubber pad 11, and both ends of the support spring 13 are connected to the rubber pad 11 through a support plastic ring 14. The rubber pad 11 and the support spring 13 can play a supporting role, and the support spring 13 and the plastic ring can not only make the support spring 13 more firmly and stably fixed, but also play a role in supporting the air holes 12, so that the air holes 12 will not be unable to ventilate due to squeezing.

[0033] The activated carbon layer 5 includes two layers of breathable cloth 15, and activated carbon 16 is arranged between the two layers of breathable cloth 15. The other end of the ventilation bag body 1 is provided with a replacement opening with an opening and closing function, and the activated carbon layer 5 is connected to the replacement opening, and a zipper 17 is arranged at the replacement opening. Opening the zipper 17 facilitates the replacement of the activated carbon 16. By providing the activated carbon layer 5, the odor in the car can be removed and the air in the car can be kept fresh.

[0034] The elastic air inlet layer 6 includes two layers of steel wire mesh 18, and a plurality of connecting springs 19 are arranged between the two layers of steel wire mesh 18. Wrapping cloth is arranged on all four sides of the elastic air inlet layer 6, and the wrapping cloth at one end of the elastic air inlet layer 6 is provided with a connecting opening, and the connecting opening is connected to the ventilation connection port 2. The steel wire mesh 18 and connecting spring 19 structure of the elastic air inlet layer 6 adopt the structure of the spring layer of the existing spring mattress. The elastic air inlet layer 6 plays a supporting role, so that when the human body is pressed on the ventilation bag body 1, it will not affect the ventilation connection port 2 to transport air to the ventilation bag body 1. The ventilation connection port 2 can be set at a suitable position of the ventilation bag body 1 to facilitate connection with the fan.

[0035] The bottom support layer 7 is made of rubber material, and a plurality of rubber particles are arranged on the side of the bottom support layer 7 close to the car seat 20. The bottom support layer 7 with rubber particles can prevent the ventilated bag body 1 from sliding on the seat 20. A strap can also be arranged on the ventilated bag body 1 to tie the ventilated bag body 1 and the seat 20 together to prevent them from moving around.

[0036] Therefore, the utility model adopts a ventilation bag of the above structure which is convenient for replacing activated carbon. Through the multi-layer structure of honeycomb air permeable layer 3, elastic support layer 4, activated carbon layer 5, elastic air inlet layer 6, and bottom support layer 7, a fan is cooperated to blow air continuously to the ventilation connection port 2, which can not only enable the driver to maintain a comfortable driving state on the car seat 20, but also purify the air in the car and remove odors in the car.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
