[0038] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0039] First, when a home bathtub needs to be renovated, since the bathtub is fixed in the bathroom and cannot be moved, the device can be placed in the bathroom and moved and supported by the first universal wheel 11 under the first base 10;

[0040] After the power distribution box 13 of the equipment is powered on, the controller 14 is connected to the power distribution box 13 according to the size of the bathtub, and input control is performed through the controller 14; and the existing finished glaze spray tank body is placed on the spray structure 2 for direct use;

[0044] When the bathtub to be processed is not in a fixed state, the bearing structure 4 can be connected to the distribution box 13 for combined use, and the bearing structure 4 can be used to support the bathtub so that the bathtub has a certain height and can be rotated for easy spraying; at the same time, the material pump 15 is used to connect the corresponding paint supply nozzle 33 on the spray rack 32, and the nozzle 33 is used to perform long-term and large-scale spraying processing;
