[0024] In order to make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0025] Embodiment 1

[0026] Figures 1-6 Shown is a schematic diagram of the overall structure of an embodiment of a permanent magnet DC booster pump of the present utility model. Please refer to Figures 1-5 , a permanent magnet DC booster pump in this embodiment includes a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 form a cavity, and a pump body 3 is installed in the cavity. A mounting plate 4 is detachably connected to the outer wall of the first housing 1 for mounting the first housing 1 on the wall. In this embodiment, a positioning groove 11 is provided on the first housing 1, and a through hole 111 is provided at the top of the positioning groove 11;

[0027] On one side wall of the mounting plate 4 close to the first housing 1, there is a hanging ear 41 corresponding to the positioning groove 11; the hanging ear 41 is connected with the positioning groove 11 in a matching manner, and the end of the hanging ear 41 extends into the through hole 111. Corresponding positioning columns 7 are provided in the inner cavities of the housing 1 and the second housing 2 for connecting the first housing 1 and the second housing 2.

[0028] Specifically, mounting holes are provided on the mounting plate 4, and the mounting plate is fixed to the wall through the mounting holes.
