[0041] Specifically, the upper section 211 of the main shaft is used to connect to the power source, so the upper and lower diameters of the upper section 211 of the main shaft vary slightly; the lower section 212 of the main shaft needs to cooperate with the pumping chamber 112, so it is designed to gradually reduce the diameter from the upper end to the lower end to facilitate installation and extracting washing liquid from the pumping chamber 112.
