The end of the transmission element 1027 near the surface 1012 is engaged with the driving button 1022, so that when the driving button 1022 is pressed by a user, the transmission element 1027 can be driven to move away from the surface 1012. Drive element 1027 is also in driving engagement with dosing pump 200, so that upon movement of drive element 1027, dosing pump 200 can be driven to pump the treatment agent outwardly. Specifically, the driving button 1022 drives the dispensing pump 200 to operate through the transmission element 1027, when the driving button 1022 is pressed, the transmission element 1027 is adapted to move away from the appearance surface 1012, and during the movement of the transmission element 1027, an external force can be applied to the dispensing pump 200 through the transmission element 1027 in transmission fit with the dispensing pump 200, so as to drive the dispensing pump 200 to pump out the treatment agent.

As shown in fig. 6 and 7, the dispensing device 100 further includes: a valve assembly 400, the valve assembly 400 being movably disposed at the dosing aperture 307 for opening or closing the dosing aperture 307. The opening and closing of the dispensing hole 307 can be controlled by controlling the movement of the valve assembly 400 at the dispensing hole 307. Thus, by controlling the opening and closing of the injection hole 307, the injection amount of the treatment agent can be controlled more favorably, and a more favorable injection effect can be achieved.

The driving part 102 can move under the driving of external force, the driving part 102 can be matched with the valve assembly 400, and the movement of the driving part 102 can drive the valve assembly 400 to open the feeding hole 307.

In other embodiments, the driving part 102 can drive the valve assembly 400 to open the dosing hole 307 and control the dosing pump 200 to operate, and the treating agent pumped by the dosing pump 200 can directly enter the dosing cavity 302 through the open dosing hole 307, so that the dosing of the treating agent is realized. That is, the valve assembly 400 and the dispensing pump 200 can be driven by one driving part 102 to work together, so that the number of driving structures in the dispensing device 1000 is reduced, the overall structure of the dispensing device 1000 is simpler, the manufacturing cost is reduced, and the valve assembly 400 and the dispensing pump 200 work together, so that the dispensing hole 307 is opened by the valve assembly 400 when the treating agent needs to be dispensed, the leakage of the dispensing device 1000 is avoided, and the device is more reliable overall. In addition, because the valve assembly 400 and the feeding pump 200 work together, the treating agent can be fed discontinuously in the washing process, the situation of liquid leakage can not occur in the feeding process, and the washing effect of the washing equipment is improved.

According to some embodiments of the present invention, the driving member 102 has a driving surface 1025, and the driving surface 1025 can be slidably engaged with the valve assembly 400 to drive the valve assembly 400 to open the aperture 307 by the driving surface 1025 in a state where the driving member 102 is pressed.

Specifically, during the process of moving the driving part 102 in the oblique downward direction, the driving surface 1025 moves simultaneously, and as the height of the driving surface 1025 is gradually reduced, the valve assembly 400 is pushed to move, so that the valve assembly 400 opens the inlet hole 307.

Thus, the driving surface 1025 can transmit the movement trend of the driving member 102 to the movement direction of the valve assembly 400 to the valve assembly 400 under the condition that the movement direction of the driving member 102 is different from the movement direction of the valve assembly 400, so as to drive the valve assembly 400 by the driving member 102.

Referring to fig. 5 and 6, according to some embodiments of the present invention, the valve assembly 400 is movable in an up-down direction, and the driving surface 1025 is located above the valve assembly 400 and extends obliquely downward in a direction close to the valve assembly 400 in a state where the driving member 102 is in the initial position.

It can be understood that, in the initial position, the contact point between the driving member 102 and the valve assembly 400 is located at the highest position, and as the driving member 102 moves obliquely downward along the installation channel 1011, the contact point between the driving member 102 and the valve assembly 400 is located at a gradually lower position, so that the valve assembly 400 moves downward under the driving of the driving member 102, and therefore, the driving surface 1025 can convert the trend of the downward movement of the driving member 102 into the trend of the downward movement of the valve assembly 400, and push the valve assembly 400 to move downward, so as to control the opening and closing of the charging hole 307 by controlling the movement of the valve assembly 400.

In addition, the driving surface 1025 extends obliquely downwards along the direction close to the valve assembly 400, so that the valve assembly 400 is prevented from being stressed transversely, the valve assembly 400 is prevented from being bent, and the moving reliability of the valve assembly 400 is prevented from being influenced.

As shown in fig. 5 and 6, in the initial position of the driving member 102, the driving surface 1025 has a position limiting portion 10251 at an end thereof away from the valve assembly 400, and the position limiting portion 10251 can cooperate with the valve assembly 400 to limit the displacement of the driving member 102.

Specifically, when the user presses the driving member 102, and the driving member 102 moves obliquely downward for a certain distance, the limiting portion 10251 is adapted to abut against the valve assembly 400, so that the valve assembly 400 limits the driving member 102 to continue moving obliquely downward, the driving member 102 can move within a certain displacement range, the driving member 102 is prevented from being jammed, and the reliability of the dispensing device 1000 is improved.

As shown in fig. 5 and 6, the driving surface 1025 extends obliquely upward along the moving direction of the driving member 102, so that the driving surface 1025 can convert the trend of the driving member 102 moving obliquely downward into the trend of the valve assembly 400 moving downward, pushing the valve assembly 400 to move downward, and controlling the opening and closing of the charging hole 307 by controlling the movement of the valve assembly 400.

Referring to fig. 5 and 6, the outlet 201 of the dosing pump 200 is located above the dosing hole 307 so that the treatment agent dosed by the dosing pump 200 can flow downwards under the influence of gravity and enter the dosing chamber 302 through the dosing hole 307, avoiding the treatment agent to be retained in the dosing device 1000.

As shown in fig. 5-7, according to some embodiments of the present invention, a valve assembly 400 includes: a movable valve plate 401 for opening and closing the discharge hole 307. By controlling the movement of the valve plate 401, the opening and closing of the throwing hole 307 can be controlled.

In order to ensure the sealing effect of the valve plate 401 against the shot hole 307, the diameter of the valve plate 401 is larger than the diameter of the shot hole 307. Specifically, the valve member 401 is located below the charge hole 307, so that the charge pump 200 can be avoided, the valve assembly 400 controls the opening and closing of the charge hole 307 by moving up and down, the charge hole 307 can be opened when the valve member 401 moves down, and the charge hole 307 can be closed when the valve member 401 moves up.

In some embodiments, the valve assembly 400 further comprises a pushing member 402, the pushing member 402 is connected to the valve plate 401, and the pushing member 402 can be moved by the driving part 102 to move the valve plate 401.

Specifically, one end of the pushing member 402 can pass through the nozzle body 301 to connect with the valve sheet 401 located below the discharge hole 307, and the other end of the pushing member 402 can cooperate with the driving surface 1025 of the driving part 102, so that the driving part 102 can drive the pushing member 402 to move downward and drive the valve sheet 401 to move to open and close the discharge hole 307.

As shown in fig. 7, in some embodiments, the nozzle body 301 has a mounting hole 3013, and the pushing member 402 is inserted into the mounting hole 3013, so that the pushing member 402 can be connected to the valve plate 401 located below the feeding hole 307.

Referring to fig. 1, a second reset element 1032 is disposed between the pushing element 402 and the nozzle body 301 to drive the pushing element 402 to drive the valve plate 401 to close the aperture 307.
