[0037] In one embodiment, one end of the output shaft 32 is connected with the brush rod 21, the other end of the output shaft 32 penetrates through the adapter 4 and is connected with the power device 31, the power device 31 is used to drive the output shaft 32 to rotate, so as to drive the brush rod 21 to rotate, thereby realizing the function of automatically cleaning the bottle body. Meanwhile, the output shaft 32 is rotatably connected with the adapter 4, the adapter 4 has the liquid storage cavity 43, the liquid storage cavity 43 is communicated with the cleaning bottle 5, so as to guide the liquid in the cleaning bottle 5 into the liquid storage cavity 43, and the liquid storage cavity 43 can be used to store the liquid; the output shaft 32 is provided with the axial channel 321 and the lateral channel 322 which are communicated with each other, the axial channel 321 is communicated with the liquid outlet channel 212 of the brush rod 21, the lateral channel 322 is located in the liquid storage cavity 43 and is communicated with the liquid storage cavity 43, so that the liquid in the liquid storage cavity 43 can be guided to the axial channel 321 through the lateral channel 322, and then be guided to the liquid outlet channel 212 of the brush rod 21, and finally be sprayed out from the liquid outlet 211, thereby realizing the effect that the cleaning liquid is guided out along with the brush rod 21, and avoiding the cleaning liquid from spilling out of the bottle and polluting the environment. Moreover, since the output shaft 32 is rotatably connected with the adapter 4, the adapter 4 does not affect the rotation of the output shaft 32, thereby realizing the function that the output shaft 32 rotates while guiding the liquid, and then the functions that the brush rod 21 rotates to clean the bottle body and the cleaning liquid is sprayed into the bottle body can be realized at the same time.

[0041] In one embodiment, the limiting protruding edge 324 is connected to the through segment 323 of the output shaft 32, and in the axial direction of the output shaft 32, the limiting protruding edge 324 can abut against the adapter 4. On the one hand, the axial displacement of the output shaft 32 is limited, and the connection stability of the output shaft 32 and the power device 31 is increased. On the other hand, the limiting protruding edge 324 has a certain sealing property, and the liquid is blocked in the liquid storage cavity 43 to avoid seepage of the liquid to the outside of the adapter 4.

The fixed cover 91 and the fixed frame 92 are installed in a clamping manner, so that the installation is simpler and the disassembly is more convenient. The fixed frame 92 is used for installing the power device 31, the pump body 7 and the circuit component 20.
