The utility model discloses use the detergent dispenser shown in figure 1 to be vertical (refer in particular to along the vertical of gravity direction) the state of putting, the detergent dispenser is in this vertical state of putting promptly when the operation.

The liquid of the utility model refers in particular to a detergent or a rinsing agent.

As shown in fig. 1-17, a detergent dispenser comprises a housing 1, a liquid storage chamber 2 and a metering chamber 3 inside the housing 1, a drive assembly 4, and one or more dosing mechanisms 5 adapted to dose a liquid; the shell 1 is provided with a filling opening 6. The liquid storage cavity 2 is used for storing liquid with a plurality of doses and is used for putting the liquid for a plurality of times; the metering cavity 3 is used for storing liquid with single input amount, determining the single input amount, and the liquid adding port 6 is used for adding liquid into the liquid storage cavity 2.

Each feeding mechanism 5 comprises a liquid inlet 501 communicated with the liquid storage cavity 2 and the metering cavity 3, a feeding opening 502 communicated with the metering cavity 3 and the washing pool, and a moving member 503 positioned in the metering cavity 3; the moving member 503 is driven by the driving assembly 4 to close or open the liquid inlet 501 and the feeding port 502.

The heights of the liquid inlet 501 or the lower edges 9 of the liquid inlets of different throwing mechanisms 5 are different along the gravity direction, and the heights of the throwing ports 502 or the upper edges 10 of the throwing ports of different throwing mechanisms 5 are different along the gravity direction. The hydraulic pressure at the opening edge is made unequal, that is, when the liquid inlet 501 or the feeding port 502 is opened, the liquid can spontaneously flow or enter the metering cavity 3 from the liquid storage cavity 2 or be discharged to the washing tank from the metering cavity 3 depending on the pressure difference existing at different positions of the edge of the liquid inlet 501 or the feeding port 502. The explanation for this feature is as follows: taking liquid inlet 501 as an example, when putting in mechanism 5 and only setting up one, liquid inlet 501 has only one, then this liquid inlet lower limb 9 is highly inequal along the direction of gravity, when putting in mechanism 5 and being provided with a plurality ofly, liquid inlet 501 also has a plurality ofly correspondingly, can design into the structure that the lower limb is highly inequal along the direction of gravity with every liquid inlet 501 this moment, or the lower limb of every liquid inlet 501 itself is highly equalling along the direction of gravity, but different liquid inlet lower limb 9 is highly inequally along the direction of gravity.

every inlet (501) or different input mechanism's (5) inlet lower limb (9) are along the direction of gravity highly inequality, every input mouth (502) or different input mechanism's (5) input mouth upper limb (10) are along the direction of gravity highly inequality.

2. The detergent dispenser of claim 1, wherein: the feeding port (502) is positioned below the liquid inlet (501), and the moving member (503) performs reciprocating linear motion between the feeding port (502) and the liquid inlet (501).

3. The detergent dispenser of claim 2, wherein: the moving piece (503) is made of flexible materials.

4. The detergent dispenser of claim 3, wherein: the moving piece (503) comprises a connecting sleeve (5031) connected with the driving component (4), an upper cover opening (5032) positioned at one end of the connecting sleeve (5031) and suitable for sealing the liquid inlet (501), and a lower cover opening (5033) positioned at the other end of the connecting sleeve (5031) and suitable for sealing the putting-in opening, wherein the upper cover opening (5032) and the lower cover opening (5033) are made of flexible materials.

5. The detergent dispenser of claim 2, wherein: the moving piece (503) is a sealing plate (13) connected with the driving component (4), and when the sealing plate (13) moves upwards, the sealing plate (13) can seal the liquid inlet (501); when the closing plate (13) moves downwards, the closing plate (13) can close the throwing opening (502).

6. The detergent dispenser of claim 2, wherein: the moving piece (503) is an upper sealing plate (14) and a lower sealing plate (15) which are connected with the driving component (4), and when the upper sealing plate (14) and the lower sealing plate (15) move upwards, the upper sealing plate (14) can seal the liquid inlet (501); when the upper closing plate (14) and the lower closing plate (15) move downwards, the lower closing plate (15) can close the throwing opening (502).

7. A detergent dispenser as claimed in any of claims 1 to 6, wherein: the height of the highest point of the upper surface (7) of the metering cavity is not higher than the height of the highest point of the lower edge (9) of the liquid inlet in the plurality of feeding mechanisms (5); the height of the lowest point of the lower surface (8) of the metering cavity is not lower than the height of the highest point of the upper edge (10) of the throwing port in the plurality of throwing mechanisms (5).

8. The detergent dispenser of claim 7, wherein: the feeding mechanism (5) is provided with one, and the lower edge (9) of the liquid inlet and the upper edge (10) of the feeding port are both curve structures with unequal heights along the gravity direction.

9. The detergent dispenser of claim 7, wherein: the two feeding mechanisms (5) are arranged, the heights of the lower edges (9) of the liquid inlets of the two different feeding mechanisms (5) are different along the gravity direction, and the heights of the upper edges (10) of the feeding ports of the two different feeding mechanisms (5) are different along the gravity direction.

10. The detergent dispenser of claim 9, wherein: each liquid inlet lower edge (9) and each throwing-in opening upper edge (10) are straight lines with the same height along the gravity direction.

11. A detergent dispenser as claimed in any of claims 1 to 6, wherein: the drive assembly (4) comprises an actuator (401) and a drive rod (402) connecting the actuator (401) and a moving member (503).

12. The detergent dispenser of claim 11, wherein: the actuator (401) is an electric motor, a solenoid valve or a wax motor.

13. The detergent dispenser of claim 1, wherein: a sealing cover is arranged at the liquid feeding port (6).
