[0031] Working principle: before using the centrifugal pump with convertible water volume, the overall condition of the device needs to be checked to determine whether it can work normally, according to Figure 1 - Figure 5As shown, a filter assembly 2 is installed inside and outside the water tank 1. During use, water is added to the water tank 1 through the inlet pipe 101, and the water flows through the filter screen. The drive motor 103 is started to rotate the impeller 105, which transports the water flow. After a period of use, some dirt accumulates on one side of the filter screen, which can be discharged by opening the drain port 1011. During filter screen installation, the telescopic spring 209 is in a compressed state, and the elastic potential energy of the telescopic spring 209 is not too small. The reaction force of the telescopic spring 209 ensures that the cover plate 203 is tightly attached to the water tank 1. A sealing gasket is provided at the bottom of the cover plate 203 to ensure the airtightness of the filter screen installation. When disassembling and cleaning the filter screen... Rotating the push rod 212 drives the turntable 211 on the rotating rod 210 to rotate. The turntable 211 can rotate at an offset, so that the turntable 211 can push the movable rod 205 upward to continue compressing the telescopic spring 209, causing the moving positioning block 207 of the rotating rod 210 to disengage from the positioning groove 208, so that the cover plate 203 loses its limit. Moreover, the movement of the movable rod 205 is achieved by rotating the push rod 212, which can be operated with less effort. Afterwards, the cover plate 203 can be lifted and the filter screen can be pulled out for cleaning. The filter assembly 2 makes it convenient for users to clean the filter screen and disassemble the filter screen. When the filter screen is installed on the water tank 1, it can ensure the sealing of the water tank 1 and prevent water leakage, thus improving practicality.

[0032] When conveying water, the water flow is separated by the partition 106 to form two channels. When the water flow rate of the pump body 102 is switched, pressing down the handle 115 causes the sliding rod 112 to move down, which in turn causes the positioning rack 114 to move down and compress the return spring 113, causing the rotating shaft 108 to lose its limit. Turning the knob 109 causes the rotating shaft 108 to rotate, which causes the baffle 107 to rotate and block one of the channels. After blocking, the handle 115 can be released. Under the action of the return spring 113, the positioning rack 114 engages with the limit gear 110, thereby positioning the rotating shaft 108 and realizing the conversion of the water volume of the pump body 102, thus improving its applicability.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
