A multifunctional sprinkler structure comprises a water motor having an outlet seat and a top cover mounted to a top-end side, and two adjusting seats and a water supply seat assembled onto a bottom-end side. The bottom-end side of the water motor has a guide groove with a restrictive hole for the extension of a switch shaft there-through. The outlet seat has a water-discharge chamber with multiple barriers extending thereon corresponding to an impeller of the water motor, and an oblique-extending central guide port matching to a spray nozzle having multiple water-guiding ribs obliquely extending towards the same direction therein. Therefore, the barriers of the outlet seat and the water-guiding ribs of the spray nozzle are utilized to correspond to the direction of the water flow so that the water discharge can be easily switched to eject either in more direct and forceful column-like spray or in more expanding spray.

The invention discloses an open type water pump. The open type water pump comprises an upper housing, a lower housing and an impeller; the impeller comprises a shaft which is positioned in the center, and a plurality of axially-extended blades which are circumferentially and uniformly distributed on the circumferential surface of the shaft; the blade is axially divided into an upper section and a lower section which are interconnected; an upper storing cavity for storing the upper section of the blade is formed in the upper housing; a lower storing cavity for storing the lower section of the blade is formed in the lower housing. The open type water pump is characterized in that the upper housing and the lower housing synchronously rotate; a bottom ring for mounting and positioning the lower housing is arranged below the lower housing. The invention also discloses a water tank type cleaner using the open type water pump.

The invention belongs to the field of pumps and particularly relates to a water jet propulsion pump which comprises a pump body and a pump shaft assembly arranged at a pump cavity of the pump body. The pump shaft assembly at least comprises a pump shaft and an impeller wheel arranged on the pump shaft; the pump shaft is of a simply supported beam structure with bearings at the two ends of the pump shaft fixedly connected, the tail end of the pump shaft and a power source of the water jet propulsion pump are in normal-running fit, and the head end of the pump shaft extends in the axial direction and is in bearing fit with a bearing assembly arranged on the pump body; bounded by an impeller wheel body, the water jet propulsion pump is divided into a water inlet area and a water outlet area, wherein the water inlet area is communicated with a liquid inlet of the pump body, and the water outlet area is used for discharging water; a reflux passageway used for reducing the hydraulic thrust at the bearing assembly is arranged between the water inlet area and the water outlet area, and the water inlet area of the pump body, the water outlet area of the pump body, gaps to be lubricated of the bearing assembly and the reflux passageway are sequentially communicated and form a circular flow channel. The water jet propulsion pump is reasonable and practical in structure, wide in working usage range and long in service life, and high-efficiency work of components within the whole water outlet area of the pump body can be effectively guaranteed.
