detailed description

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

Please refer to Fig. 1 to Fig. 4 together, the air pumping box of the present utility model comprises a box body 1, a box cover 2, and this box body 1 has ring wall 11, bottom wall 12, and central has chamber 13, ring wall 11 There is an opening 14 on the upper side, and a first pivot joint 15 is provided on the upper side of the ring wall 11, a first fastening part 16 is provided in the center of the opposite side, and an accommodating part 17 capable of accommodating a control circuit board 171 is provided on the outside of the ring wall 11 A heating body 18 electrically connected to the control circuit board 171 is arranged under the bottom wall 12 , and a pressure relief valve 19 is arranged on the box body 1 .

The box cover 2 can cover the opening 14 of the box body 1, and has a plastic upper cover 21, a plastic lower cover 22, and a reinforcing plate 23. One side of the upper cover 21 has a first pivot joint with the first pivot joint 15. Two pivot joints 211, this side is the pivot joint side, and the opposite side has a second buckle joint 212 corresponding to the position of the first buckle joint 16, and this side is the buckle joint side; the upper cover is also provided with an exhaust hole 213, corresponding to Engagement posts 214 are arranged on the buckle side in the horizontal direction and close to the inner surface of the two sides of the upper cover 21; The pad body 221 is combined, and the bottom surface of the lower cover 22 is provided with an air intake hole 222 and an air pump 223.
