An automatic powder feeding and distributing device comprises a powder storage cavity 1, a driver 2, an eccentric wheel 3, a push rod 4, a stopper 5, a powder outlet cavity 6, a first switch 7 and a second switch 8;

the powder storage cavity 1 is provided with a powder inlet 11 and a powder outlet 12, the right side wall of the push rod 4 is provided with a first opening 41, the left side wall of the push rod 4 is provided with a second opening 42, the powder outlet 12 is communicated with the first opening 41, and the second opening 42 is communicated with the powder outlet cavity 6;

the eccentric wheel 3 is provided with a first bump 30, one end of the push rod 4 is provided with a sliding groove 40 along the left-right direction, the driving end of the driver 2 is connected with the eccentric wheel 3, and the first bump 30 is slidably arranged on the sliding groove 40; the other end of the push rod 4 is fixed with the blocking piece 5, the push rod 4 is arranged along the up-down direction, the other end of the push rod 4 is arranged in the powder outlet cavity 6 in a manner of sliding up and down, the blocking piece 5 is arranged in the powder outlet cavity 6, the powder outlet cavity 6 is provided with a powder feeding port 60, when the push rod 4 drives the blocking piece 5 to move upwards, the powder feeding port 60 is opened, and when the push rod 4 drives the blocking piece 5 to move downwards, the powder feeding port 60 is closed;

the left side of the push rod 4 is provided with a trigger point for turning on the first switch 7 and the second switch 8.

As shown in figures 1, 3 and 4, when the automatic feeding and distributing device is used, the powder inlet 11 is opened firstly, dish washing powder is added into the powder storage cavity 1 until the dish washing powder is filled with the whole powder storage cavity 1, at the moment, the powder inlet 11 is closed, the airtightness inside the powder storage cavity 1 is guaranteed, and the dish washing powder is prevented from being wetted and agglomerated to influence the operation of a dish washing machine. Store up the powder that washes dishes in the powder chamber 1 and pass through throw out powder outlet 12, and pass through first opening 41 is thrown in the inside of push rod 4, the inside of push rod 4 is provided with transportation channel 43, and the powder that washes dishes passes through transportation channel 43, and passes through second opening 42 is thrown in it is inside to go out powder chamber 6. Since the powder outlet chamber 6 is provided with the powder feeding port 60, in an initial state, the powder feeding port 60 is blocked by the blocking member 5, that is, in a closed state, when the driver 2 is started, the driver 2 is a motor in this embodiment, and the driver 2 drives the eccentric wheel 3 to rotate, so that the first protrusion 30 slides left and right in the chute 40, and the push rod 4 is driven to move up and down. When the push rod 4 moves upwards, the blocking member 5 moves upwards along with the push rod, the powder feeding port 60 is opened, and the dishwashing powder in the powder outlet cavity 6 is fed into a washing cavity of the dishwasher through the powder feeding port 60; when the push rod 4 moves downwards, the blocking piece 5 moves downwards along with the push rod, the powder throwing port 60 is closed, and the dish washing powder in the powder outlet cavity 6 stops throwing the powder into the washing cavity of the dish washing machine, so that the throwing of the dish washing powder can be realized. Further, when the powder feeding port 60 is in a closed state, the whole automatic feeding and dispensing device is isolated from the inner container of the dishwasher, and water vapor in the inner container of the dishwasher cannot enter the whole automatic feeding and dispensing device to achieve a sealing effect.

Because the left side of push rod 4 is provided with and opens first switch 7 with the trigger point of second switch 8, works as in the in-process of push rod 4 up-and-down motion, the left side wall of push rod 4 can touch first switch 7 or the trigger point of second switch 8 triggers first switch 7 or second switch 8, first switch 7 or second switch 8 is used for calculating the number of times of push rod 4 up-and-down motion, can control the throwing in number of times of washing the dishes powder more accurately.

In the scheme, the driver 2 drives the push rod 4 to move back and forth and also drives the stopper 5 to move back and forth, so that the powder throwing port 60 of the powder outlet cavity 6 is opened or closed, and the dish washing powder is thrown in. The first switch 7 or the second switch 8 can be triggered in the reciprocating process of the push rod 4, and accordingly repeated throwing of the dishwashing powder is further achieved.

Preferably, a transport channel 43 is arranged inside the push rod 4, and the transport channel 43 comprises a first inclined plate 431 and a second inclined plate 432;

one end of the first inclined plate 431 is fixed to the right inner wall of the push rod 4 and is located above the first opening 41, and the other end of the first inclined plate 431 is fixed to the left inner wall of the push rod 4 and is located above the second opening 42; one end of the second inclined plate 432 is fixed to the right inner wall of the push rod 4, and the end is located below the first opening 41, and the other end of the second inclined plate 432 is fixed to the left inner wall of the push rod 4, and the end is located below the second opening 42.

In this embodiment, as shown in fig. 3, the arrangement of the first inclined plate 431 and the second inclined plate 432 guides the transportation of the dishwashing powder, so that the dishwashing powder can be quickly transported from the first opening 41 to the second opening 42.

Preferably, the outer wall of the left side of the push rod 4 is provided with a second bump 44, and the cross section of the second bump 44 is triangular.

In this embodiment, as shown in fig. 2, since the second protrusion 44 is disposed on the outer wall of the left side of the push rod 4, the trigger point of the first switch 7 or the second switch 8 can be touched during the up-and-down movement of the push rod 4, so as to trigger the first switch 7 or the second switch 8. Since the cross section of the second protrusion 44 is triangular, the structure is stable, and the trigger point of the first switch 7 or the second switch 8 can be more easily touched by the vertex angle end of the triangle.

Preferably, the first switch 7 and the second switch 8 are both micro switches with contacts.

In this embodiment, as shown in fig. 1, the first switch 7 and the second switch 8 are both microswitches with contacts, and the push rod 4 touches the trigger point to turn on and off the microswitches through back and forth movement, so that the turning on and off of the first switch 7 and the second switch 8 is sensitive and convenient.
