[0020] 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 the embodiments.

[0021] Refer to Figures 1-4, a water pump housing, comprising a housing 1, a base 2 and a clamping component 4. The base 2 is arranged at the bottom of the housing 1 for accommodating and protecting the internal components of the water pump. A clamping piece 3 is arranged at the bottom end of the base 2, and a clamping component 4 is slidably engaged with the clamping piece 3. The clamping component 4 includes a clamping ring 401. A guiding groove ring 403 is formed inside the clamping ring 401. Sliding grooves 404 are formed on both side walls of the guiding groove ring 403. Three clamping grooves 402 are formed on the cross section of the clamping ring 401. Each clamping groove 402 communicates with the guiding groove ring 403. The clamping grooves 402 and the guiding groove ring 403 form a clamping groove. The clamping piece 3 is engaged in the clamping groove. The number of the clamping pieces 3 is three. The clamping piece 3 is in an "L" shape. The short board of the clamping piece 3 is engaged on the clamping groove 402, and the long board of the clamping piece 3 is engaged on the guiding groove ring 403. When the clamping piece 3 is inserted into the clamping groove, it slides into the guiding groove ring 403 and is finally clamped into the clamping groove 402 to realize clamping and fixing, so that the housing 1 can be quickly installed and disassembled. During disassembly, only reverse operation is needed, saving the time and effort for installation and maintenance.

[0022] A clamping bar 5 is slidably engaged with the guiding groove ring 403. Limiting bars 6 are arranged on both sides of the clamping bar 5. The limiting bars 6 are engaged in the sliding grooves 404. The sliding grooves 404 are used to guide the sliding of the clamping bar 5. The clamping bar 5 is in a semi-circular arc shape. Limiting bars 6 are arranged on both the upper and lower sides of the clamping bar 5. The clamping bar 5 is slidably connected to the sliding groove 404 through the limiting bars 6. The number of the clamping bars 5 is three. The three clamping bars 5 are arranged in a surrounding shape inside the guiding groove ring 403. After the clamping piece 3 is inserted into the clamping groove, the clamping bar 5 can slide in the guiding groove ring 403, so that the two ends of the clamping bar 5 contact the short board of the clamping piece 3, further fixing the clamping piece 3 and preventing it from loosening or falling off during use;

[0023] A row of water inlet holes 8 are formed through the chamber 7. The water inlet holes 8 are used for the entry of water. A driver 9 is installed at the bottom of the inner wall of the chamber 7. A blade 10 is installed on the driving rod of the driver 9. The chamber 7 is in a cylindrical shape with an open top end.
