Example 2:
this embodiment is different from embodiment 1 described above in that the arrangement of the water bag portion is different; in the embodiment 2, the water bag portion includes a folded bag body 20, and the folded bag body 20 includes a bag bottom 201 positioned on the side of the closed side of the side cover 102, a positioning folding wall 202 positioned on the side near the first opening 12, a first folding wall 203 positioned on the side near the top cover, and a second folding wall 204 positioned on the two sides of the side cover 102.
Accordingly, the drainage openings 28 are provided on the positioning folding wall 202.
When the connecting cover is opened, the bag bottom 201, the positioning folding wall 202, the first folding wall 203 and the two second folding walls 204 can be unfolded to form the water receiving cavity 27 with the bag opening 22.
Specifically, a first magic tape 205 is arranged on the side surface of the first folding wall 203, which is back to the water receiving cavity 27, and second magic tapes 206 are arranged on the side surfaces of the second folding walls 204, which are on the two sides and face to the water receiving cavity 27; the side surface of the bag bottom 201 facing the side cover 102 on the closed side is provided with a third magic tape 207, and the side surface of the positioning folding wall 202 facing away from the water receiving cavity 27 is provided with a fourth magic tape 208.
When the folded bag body 20 needs to be unfolded, the upper part of the first folding wall 203 is partially turned over above the top cover 101, and the first magic tape 205 is adhered to the non-closed side of the top cover 101; then the fourth magic tape 208 is stuck to the front position of the positioning bracket 9 facing the first opening 12; the third hook and loop fastener 207 is fixedly adhered to the side cover 102; thereby completing the unfolding support of the folded bag body 20 to form the water receiving chamber 27.
When the foldable bag body 20 needs to be stored, the first foldable wall 203 is firstly detached to be placed on the bag bottom 201, and the first magic tape 205 faces to the upper side; then the second folding walls 206 on both sides are folded to the position of the bag bottom 204, so that the lower parts of the second folding walls 206 on both sides are adhered to the first magic tape 205, and meanwhile, the second magic tape 206 is adhered to the bag bottom 201; thereby completing the storage of the folded bag body 20.
Because the folding bag body 20 is pasted and positioned by various magic tapes, the folding bag body 20 can be detachably arranged relative to the connecting cover, so that a user can conveniently replace or clean the folding bag body.
The above is only the preferred embodiment of the present invention, and to the technical personnel in the technical field, without departing from the present invention, the embodiment can still be modified, and the corresponding modification should also be regarded as the protection scope of the present invention.
