Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, a water pump provided by the present utility model includes:

[0027] Casing 1;

[0028] Water pumping mechanism 2, and the water pumping mechanism 2 is arranged inside the casing 1;

[0029] Filling mechanism 3, and the filling mechanism 3 is arranged inside the casing 1. The filling mechanism 3 includes a bottom filling ring 31. The top of the bottom filling ring 31 is fixedly connected with a connecting rod 32. The surface of the connecting rod 32 is movably connected with a rotor protection ring 33. A baffle 34 is arranged on the left side of the rotor protection ring 33. A weight reduction groove 35 is opened on the right side of the baffle 34.

[0030] Refer toFigure 1 The casing 1 includes a base 101. The top of the base 101 is movably connected to a housing 102, and the top of the housing 102 is movably connected to a top cover plate 103. The filling mechanism 3 is disposed inside the housing 102.

[0031] As a technical optimization solution of the present utility model, by providing the casing 1, the pumping mechanism 2 and the filling mechanism 3 can be wrapped. The user first installs the pumping mechanism 2 and the filling mechanism 3 inside the housing 102, then installs the top cover plate 103 on the top of the housing 102, and then installs the base 101 on the bottom of the housing 102.

[0032] Reference Figure 3 The pumping mechanism 2 includes a rotor 21. The output end of the rotor 21 is fixedly connected to a rotating rod 22. The bottom of the rotating rod 22 is movably connected to a water suction blade 23. The rotor 21 is disposed inside a rotor protection ring 33.

[0033] As a technical optimization solution of the present utility model, by providing the pumping mechanism 2, the inside can be pumped. The user drives the rotor 21, the rotor 21 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the water suction blade 23 to rotate. The water at the bottom of the base plate 1011 is pumped through the rotation of the water suction blade 23.

[0034] Reference Figure 6 The base 101 includes a base plate 1011. The bottom of the base plate 1011 is fixedly connected to a support plate 1012. A water inlet hole 1013 is formed in the bottom of the base plate 1011. The height of the support plate 1012 is less than one millimeter.

[0035] As a technical optimization solution of the present utility model, by providing the base 101, the housing 102 can be supported. Since the height of the base plate 1011 is less than one millimeter, it will be pumped out when the water level is higher than one millimeter, thus ensuring that the height of the residual water does not exceed one millimeter.

[0036] Reference Figure 4 The top of the top cover plate 103 is provided with a bolt 4. The bottom of the bolt 4 penetrates through the top cover plate 103 and extends into the inside of the baffle 34.

[0037] As a technical optimization solution of the present utility model, by providing the bolt 4, the baffle 34 can be fixed to prevent the baffle 34 from shaking.

[0038] Reference Figure 4 The top of the top cover plate 103 is fixedly connected to a handle 5. The surface of the handle 5 is provided with anti-slip lines.

[0039] As a technical optimization solution of the present utility model, by providing a handle 5, the contact area between the top cover plate 103 and the hand can be increased, thereby facilitating the user to lift the top cover plate 103.

[0040] The working principle and usage process of the present utility model: During use, the user installs the bottom filling ring 31 on the top of the base plate 1011, then sleeks the rotor protection ring 33 on the surface of the connecting rod 32. The rotor protection ring 33 fixes the bottom filling ring 31 through the connecting rod 32. Then, the baffle 34 is installed at the bottom of the top cover plate 103 to block the water outlet of the top cover plate 103 and adjust the size of the water outlet at the top of the top cover plate 103. The space inside the housing 102 is reduced by the bottom filling ring 31, and the efficiency of the pumping mechanism 2 is increased by reducing the space. The rotor 21 drives the rotating rod 22 to rotate through the output end, and the rotating rod 22 drives the water absorbing blade 23 to rotate. The water inlet hole 1013 on the base plate 1011 is pumped by the rotation of the water absorbing blade 23. Since the height of the base plate 1011 is less than one millimeter, it will be pumped out when the water level is higher than one millimeter, thus ensuring that the height of the residual water does not exceed one millimeter.

[0041] In summary: For this water pump, by providing the filling mechanism 3, the inside of the casing 1 can be filled, the volume inside the casing 1 can be reduced to increase the efficiency of the pumping mechanism 2, and then the size of the water outlet of the casing 1 is adjusted by the baffle 34 in the filling mechanism 3, and the suction force is adjusted by adjusting the size of the water outlet of the casing 1. When the user uses the water pump, there will be no water residue higher than one millimeter at the bottom of the water pump, which can ensure the height of the residual water and thus ensure the normal use of the user.
