In the related art, in order to prevent water in the water wheel bin from overflowing into the distribution bin, a sealing ring is often arranged at a matching position of the water wheel bin and the distribution bin, so that the transmission device outputs power and meanwhile the water is prevented from overflowing into the distribution bin. However, after the sealing ring is arranged, the resistance of the transmission device is increased, so that the treatment agent feeding device is difficult to drive by the impeller under the condition of low water pressure, namely, the starting torque required by the treatment agent feeding device is large, the impeller cannot work normally under the condition of low water pressure, the application of the treatment agent feeding device driven by water flow is greatly limited, and if the sealing ring fails, the working reliability of the treatment agent feeding device is also influenced.

Based on this, in various embodiments of this application, form drainage structure on the water wheel storehouse, can in time remove from the water of water wheel storehouse overflow to can save seal structure's such as sealing washer setting, both can avoid giving the interior transmission's of storehouse resistance increase back to be difficult to the defect of work under the low water pressure, can not take place again because of the influence that the water of the overflow that sealed inefficacy leads to produced drive gear transmission, can widen water pressure operating range, and improve the reliability that the device was put in to the finishing agent worked.

It is understood that the water retaining ring 312 may be located in the distribution bin 1B, and the water retaining ring 32 may also be disposed between the water wheel bin 1A and the distribution bin 1B. The water retaining ring 32 is used for preventing water overflowing from the matching position of the transmission rod 31 and the upper wall body of the water wheel bin 1A from flowing upwards to the gear ring 312. It can be understood that the through hole that supplies the transfer line 31 to pass through is seted up to the upper wall body of water wheel storehouse 1A, transfer line 31 and this through hole clearance fit, when the water pressure is great in water wheel storehouse 1A, the water that does not in time drain away in water wheel storehouse 1A can upwards spill over through the clearance between this through hole and transfer line 31, at this moment, transfer line 31 can rotate under the drive of impeller 2, water blocking ring 32 that is fixed in on transfer line 31 can effectively block the water that upwards spills over and overflow to on water blocking ring 32 to avoid the water that upwards spills over to produce the influence to transmission such as gear.

Therefore, the treating agent feeding device can normally work within the water pressure range of 0.03MPa to 1.0MPa, so that the treating agent feeding device has wide application prospect, for example, the treating agent feeding device can be applied to household appliances such as washing machines or dish washing machines.

For example, the reduction mechanism 4 may comprise one or more reduction gears, so as to transmit the power of the transmission rod 31 to the dosing mechanism 5.

In some embodiments, the water pan also receives the treatment agent from the dispensing mechanism 5, and an outlet is provided on the water pan for mixing the water with the treatment agent and discharging the mixed water. Thus, the overflowing water and the thrown treating agent can be thrown into the working cavity of the washing equipment through the outlet by the water receiving tray. It is understood that in other embodiments, the water pan may also only receive water drained by the drainage structure, and water accumulated on the water pan may be cleaned periodically by manual work or an outlet for draining accumulated water may be provided on the water pan.

For example, the first vane 22 is curved in a clockwise direction, which facilitates the water flow entering from the first inlet to apply a counterclockwise pressure to the first vane 22, thereby driving the rotor 21 to rotate in a counterclockwise direction. The second vane 23 is curved in a counterclockwise direction to apply a clockwise pressure to the second vane 23 by the water flow entering from the second inlet, thereby driving the rotating body 21 to rotate in a clockwise direction. Thus, the double-sided blades of one impeller 2 can be utilized to efficiently rotate forwards or backwards under the action of water flow, and the rotating torque in different directions can be output favorably through the rotating body 21.

It will be appreciated that the baffle 24 is positioned between the first and second sets of blades to separate the first and second blades 22 and 23, reducing the likelihood that the flow entering the first inlet will act on the second set of blades and the likelihood that the flow entering the second inlet will act on the first set of blades, improving the hydrodynamic conversion efficiency.
