[0039] In some preferred embodiments, the water outlet nozzle 4 is extended toward the top of the pump housing 1 , and the height of the water outlet nozzle 4 is higher than the top surface height of the pump housing 1 .
[0040] Specifically, in order to prevent water leakage and ensure sufficient drainage space of the overall structure, in the present embodiment, the water outlet 4 is extended toward the top of the pump casing 1, and the height of the water outlet 4 is higher than the top surface height of the pump casing 1, which is used to increase the water outlet space of the water outlet 4. When the height of the water outlet 4 is higher than the top surface height of the pump casing 1, the water outlet 4 is further away from the water inlet 301 at the bottom of the pump casing 1, thereby ensuring that the overall structure has sufficient drainage space to avoid accidental water leakage.

The first drainage hole corresponds to the second drainage hole and is connected. The output end of the second drainage hole is located at the lowest point of the surface of the bottom of the pump cover 2. Through the arrangement of the above structure, the exhaust hole is closer to the water tank. Compared with the arrangement of the drainage hole 5 at the side or upper part of the pump housing 1, it can not only drain water normally, but also prevent the phenomenon of water spraying due to unexpected circumstances. At the same time, it further enhances the effect of balancing air pressure, and ensures the silent effect and working stability of the overall structure during operation. More specifically, the second drainage hole is located at the lowest point of the surface edge of the bottom of the pump cover 2 to avoid the phenomenon of water spraying out of the drainage hole 5 due to low water level.

By setting the above structure, the height of the connecting portion 1102 is higher than the height of the fixing portion 1101, which can bring a more stable and firmer supporting effect to the overall structure, that is, the pump casing 1 and the fixing portion 1101 are in a relatively lower position relative to the connecting portion 1102. At this time, the center of gravity of the overall structure is lower, and it has better stability after installation, ensuring that the overall structure is in a stable connection state in the mobile air conditioner, thereby ensuring the silent effect and working stability during operation.
[0047] In some preferred embodiments, the fixing portion 1101 is integrally connected to the radial outer wall of the bottom of the pump housing 1 .

[0050] Specifically, in order to make the overall structure obtain a good supporting effect and avoid shaking or unstable connection, in this embodiment, the height of the connecting portion 1102 is between the top height of the pump housing 1 and the bottom height of the pump housing 1, and the free end of the connecting portion 1102 is provided with a mounting hole 11021 for connecting the mobile air conditioner. Through the above-mentioned structure, the height of the connecting portion 1102 is between the top height of the pump housing 1 and the bottom height of the pump housing 1, so that the mounting plate 11 is located at a reasonable installation position, with sufficient connection space, and can be more conveniently connected to the mobile air conditioner. The free end of the connecting portion 1102 is provided with a mounting hole 11021 for connecting the mobile air conditioner, which can realize a convenient detachable connection with the mobile air conditioner through bolts or other components, while ensuring the firmness and stability of the connection after installation, thereby ensuring that the overall structure plays a silent effect and drainage efficiency during drainage.

Under the connection of the graphite bearing 9, the sound emitted by the rotor 7 during operation is close to a silent state without any noise phenomenon, thereby enhancing the user experience comfort. In addition, the hierarchical connection structure of the pump casing 1, the pump cover 2, and the pump filter cover 3 is also conducive to enhancing the operational convenience of the overall structure when disassembly and assembly are required. After a period of use, it is also convenient to carry out cleaning work after disassembly; the pump cover 2 is connected to a middle cover 10 on the side facing the power assembly, and the middle cover 10 is used as a mounting carrier for the graphite bearing 9 and the rotor 7 to ensure their stable operation. An axial hole 1001 is opened at the geometric center position of the middle cover 10, and the rotating shaft 701 of the rotor 7 close to the axial hole 1001 is rotatably connected to the axial hole 1001. Through the above structure, the middle cover 10 is provided with an axial hole 1001 at the geometric center position, which is used to be rotatably connected with the rotating shaft 701 of the rotor 7 close to the axial hole 1001 on the one hand, as an installation carrier, and is used to play a positioning role, that is, it plays a positioning and connection role for the graphite bearing 9 and the rotor 7, ensuring that the graphite bearing 9 and the rotor 7 are in an accurate and reasonable installation position, so as to stably exert a silent working state and enhance the user experience comfort; the pump cover 2 is provided with a slide groove along the axial direction on the side facing the power assembly, and the radial outer wall of the middle cover 10 is provided with a slide bulge along the axial direction, and the slide bulge is adaptively connected with the slide groove.Through the above-mentioned sliding protrusion and sliding groove matching connection structure, the pump cover 2 plays a guiding and positioning role in the connection with the middle cover 10, ensuring that the middle cover 10 can be conveniently and accurately positioned and installed with the pump cover 2, and then after the middle cover 10 is installed, the positioning and installation accuracy of the graphite bearing 9 and the rotor 7 is guaranteed, ensuring that the rotor 7 has a silent effect when rotating, avoiding noise, and enhancing the user experience comfort; the depth of the water inlet 301 is greater than the axial width of the impeller 8, and the impeller 8 is located in the coverage area of the water inlet 301. Through the setting of the above-mentioned structure, the motion trajectory of the impeller 8 is located in the coverage area of the water inlet 301, which can not only play a role in drainage, but also improve the operating accuracy of the impeller 8, so that its drainage function can be fully exerted in the coverage area of the water inlet 301. At the same time, in conjunction with the filtering water inlet function of the pump filter cover 3, the stability and efficiency of the drainage process are further enhanced, thereby not only eliminating the noise during work, but also further improving the drainage efficiency.
