The second arm 32 comprises a second limiting portion 322, the second limiting portion 322 is located at one end of the second arm 32 away from the second switch assembly 34, and the second limiting portion 322 is connected with one end of the electromagnetic valve assembly 4. The first limiting portion 312 and the second limiting portion 322 are located at the same end of the electromagnetic valve assembly 4, and the first limiting portion 312 and the second limiting portion 322 are arranged at intervals, that is, a spacing D is provided between the first limiting portion 312 and the second limiting portion 322.

[0039] Please refer to Figure 2 and Figure 9 As shown, the electromagnetic valve assembly 4 comprises a valve core component 41 and a coil 42, the valve core component 41 comprises a first section 411 and a second section 412 connected with the first section 411, and the coil 42 comprises a first hole 421. The electromagnetic valve assembly 4 adopts a semi-closed structure, reduces the loss of magnetic flux, increases the attraction of the coil, and increases the reliability of opening of the cover body 2.

[0040] Please refer to Figure 9 and Figure 13As shown, the first limiting part 312 comprises a first clamping groove 3121. The first section 411 and the second section 412 are approximately cylindrical, the diameter of the first section 411 is smaller than that of the second section 412, the length of the first clamping groove 3121 in the radial direction of the first section 411 is smaller than the diameter of the second section 412, the length of the first clamping groove 3121 in the radial direction of the first section 411 is greater than the diameter of the first section 411, and the first section 411 is at least partially located in the first clamping groove 3121, so that the first limiting part 312 and the second limiting part 322 can move along the axial direction of the valve core component 41 within the range of the first section 411, and the second section 412 can block the first limiting part 312 and the second limiting part 322 from moving out of the range of the first section 411. The first limiting part 312 and the second limiting part 322 are both connected to one end of the valve core component 41 close to the second section 412, and the first limiting part 312 is closer to the second section 412 than the second limiting part 322.

[0041] Please refer to Figure 5 to Figure 7 As shown, the electromagnetic valve assembly 4 also has a power-off state, a first working current or voltage state, and a second working current or voltage state, so that the valve core component 41 has a first position L1, a second position L2, and a third position L3. The valve core component 41 is at least partially located in the first hole 421, the length of the valve core component 41 in the first hole 421 when the valve core component 41 is in the first position L1 is a first length, the length of the valve core component 41 in the first hole 421 when the valve core component 41 is in the second position L2 is a second length, and the length of the valve core component 41 in the first hole 421 when the valve core component 41 is in the third position L3 is a third length, the third length is greater than the second length, and the second length is greater than the third length. When the length of the valve core component 41 in the first hole 421 is constant, the greater the voltage of the electromagnetic valve assembly 4, the greater the force generated by the valve core component 41; when the voltage of the electromagnetic valve assembly 4 is constant, the longer the length of the valve core component 41 in the first hole 421, the greater the force generated by the valve core component 41, therefore, when the dispenser is miniaturized, the length of the valve core component 41 in the first hole 421 can be appropriately reduced, and the voltage of the electromagnetic valve assembly 4 can be increased to meet the required force of the valve core component 41; when a small voltage is used to control the electromagnetic valve assembly 4, the length of the valve core component in the first hole 421 can be extended to meet the required force of the valve core component 41.

[0042] Please refer to Figure 5As shown, when the solenoid valve assembly 4 is in the power-off state, the cover 2 is in the closed state, the first component 21 and the second component 331 are in the locked state, and the valve core component 41 is in the first position. The first elastic member 51 and the second elastic member 52 are in the reset state, at this time, the elastic force generated by the first elastic member 51 is small, and the elastic force of the first elastic member 51 is sufficient to keep the first arm 31 to keep the valve core component 41 in the first position L1; the elastic force generated by the second elastic member 52 is small, and the elastic force of the second elastic member 52 is sufficient to keep the second arm 32 to keep the second switch assembly 32 in the closed position of the brightener pouring position, and the valve core component 41 only needs to overcome the small elastic force of the first elastic member 51 and the second elastic member 52.

[0043] Please refer to Figure 6 As shown, when the solenoid valve assembly 4 is in the first working current or voltage state, the voltage of the solenoid valve assembly 4 is low, the valve core component 41 moves from the first position L1 to the second position L2, and the valve core component 41 drives the first switch assembly 33 through the first arm 31, so that the first component 21 and the second component 331 are partially displaced, but the cover 2 does not open the containing cavity 13. At this time, the first elastic member 51 receives a greater elastic force relative to the power-off state of the solenoid valve assembly 4, and the second elastic member 52 has no change or a small change that can be ignored relative to the power-off state of the solenoid valve assembly 4, and the valve core component 41 overcomes the elastic force generated by the first elastic member 51. The first limiting portion 312 and the second limiting portion 322 are in contact under the driving of the valve core component 41. At this time, the resistance to overcome the elastic force generated by the first elastic member 51 and drive the first arm 31 is small, and the solenoid valve assembly 4 needs to generate a greater force relative to the power-off state of the solenoid valve assembly 4 to drive the first arm 31, so that the starting voltage of the solenoid valve assembly 4 is low, which improves the reliability of the solenoid valve assembly 4 and reduces the energy consumption.

[0044] Please refer to Figure 7 As shown, when the solenoid valve assembly 4 is in the second working current or voltage state, the voltage of the solenoid valve assembly 4 is increased compared to the first working current or voltage state, the valve core component 41 continues to move, and the valve core component 41 moves from the second position L2 to the third position L3. The valve core component 41 drives the first switch assembly 33 through the first arm 31, so that the first component 21 is separated from the second component 331, the cover 2 opens the containing cavity 13, and the dishwashing powder starts to be poured. And the first limiting portion 312 and the second limiting portion 322 are in abutment, the valve core component 41 drives the first arm 31, the first arm 31 drives the second switch assembly 34 through the second arm 32, or the valve core component 41 directly drives the second switch assembly 34 through the second arm 32. At this time, the first elastic member 51 and the second elastic member 52 are both stretched and deformed under stress, and the valve core component 41 needs to generate a greater force relative to the low-voltage power-on state of the solenoid valve assembly 4 to overcome the elastic force generated by the first elastic member 51 and the second elastic member 52.

[0045] When the valve core component 41 moves from the second position L2 to the third position L3, the cover 2 opens the accommodating cavity 13, and when the valve core component 41 moves to the third position L3, the first component 21 has been separated from the second component 331 at this time, and the position of the second component 331 relative to the first component 21 has a certain margin, which improves the reliability of the opening of the cover 2. At the same time, while ensuring the reliability of the opening of the cover 2, the distance of the movement of the valve core component 41 is small, which can reduce the design size of the electromagnetic valve assembly 4, and is conducive to the miniaturization of the dispenser.

[0046] Please refer to Figure 5 When the cover 2 opens the accommodating cavity 13 for a period of time, the electromagnetic valve assembly 4 is switched from the second working current or voltage state to the power-off state, the first arm 31 is reset under the action of the first elastic member 51, the second arm 32 is reset under the action of the second elastic member 52, and the first arm 31 drives the valve core component 41 to move from the third position L3 to the first position L1. In the process of opening the cover 2, when the valve core component 41 moves from the first position L1 to the third position L3, the electromagnetic valve assembly 4 is immediately switched from the power-on state to the power-off state, and the power-on time of the electromagnetic valve assembly 4 is short. After the electromagnetic valve assembly 4 is powered off, the first arm 31, the second arm 32, the first elastic member 51, the second elastic member 52 and the valve core component 41 are reset.

[0047] In some embodiments, please refer to Figure 6 When the electromagnetic valve assembly 4 is in the first working current or voltage state, the valve core component 41 moves from the first position L1 to the second position L2, the valve core component 41 drives the first switch assembly 33 through the first arm 31, so that the first component 21 is separated from the second component 331, and the cover 2 opens the accommodating cavity 13. At this time, the first elastic member 51 receives a greater elastic force relative to the electromagnetic valve assembly 4 in the power-off state, the second elastic member 52 has no change or a change that can be ignored relative to the electromagnetic valve assembly 4 in the power-off state, and the valve core component 41 only needs to overcome the elastic force generated by the first elastic member 51 and the resistance of the rotation of the first arm 31 to open the cover 2. Under the driving of the valve core component 41, the first limiting portion 312 and the second limiting portion 322 abut, the distance of the movement of the valve core component 41 is maximum, which can improve the cover-opening margin of the second component 331 relative to the first component 21, and improve the reliability of the opening of the cover 2.

[0048] Please refer to Figure 5As shown, when the cover 2 opens the accommodating cavity 13 for a period of time, the electromagnetic valve assembly 4 is switched from the first working current or voltage state to the power-off state, the first arm 31 is reset under the action of the first elastic member 51, and the first arm 31 drives the valve core component 41 to move from the second position L2 to the first position L1. During the opening of the cover 2, when the valve core component 41 moves from the first position L1 to the second position L2, the electromagnetic valve assembly 4 is immediately switched from the first working current or voltage state to the power-off state, the energization time of the electromagnetic valve assembly 4 is short, and the energy consumption is reduced. During the whole opening process of the cover 2, the second elastic member 52 has no change or the change is small and negligible, and the electromagnetic valve assembly 4 does not need to overcome the elastic force of the second elastic member 52. Only the elastic force generated by the first elastic member 51 and the resistance to drive the first arm 31 to rotate, the electromagnetic valve assembly 4 needs to generate a smaller force, so that the starting voltage of the electromagnetic valve assembly 4 is lower, so that the electromagnetic valve assembly 4 can overcome the elastic force generated by the first elastic member 51 and the resistance to drive the first arm 31 to rotate to drive the first arm 31 to move, thereby improving the reliability of the electromagnetic valve assembly 4 in operation and reducing energy consumption.

[0049] Please refer to Figure 7 As shown, during the process of putting in the detergent, the electromagnetic valve assembly 4 is first switched from the power-off state to the first working current or voltage state, and then to the second working current or voltage state, the valve core component 41 moves from the first position L1 to the second position L2, and the voltage of the electromagnetic valve assembly 4 is increased, so that the valve core component 41 moves from the second position L2 to the third position L3, the first limiting portion 312 and the second limiting portion 322 abut, the valve core component 41 drives the first arm 31, the first arm 31 drives the second switch assembly 34 through the second arm 32, or the valve core component 41 directly drives the second switch assembly 34 through the second arm 32. At this time, the first elastic member 51 and the second elastic member 52 are both stretched and deformed under stress, and the valve core component 41 needs to generate a greater force relative to the low-voltage energization state of the electromagnetic valve assembly 4 to overcome the elastic force generated by the first elastic member 51 and the second elastic member 52. Due to the fluidity of the brightener, the duration of the energization of the electromagnetic valve assembly 4 can be used to control the amount of the brightener put in each time, and the number of times of turning on the electromagnetic valve assembly 4 can be used to further control the total amount of the brightener put in.

[0050] And when the cover 2 is opened, the voltage required by the electromagnetic valve assembly 4 is relatively low compared with the voltage required for putting in the detergent, which improves the stability of opening the cover and improves the diversity of the electromagnetic valve assembly 4. During the opening process, the electromagnetic valve assembly 4 does not drive the second arm 32 to move, which can reduce the leakage of the brightener during the non-pouring period.

[0051] Please refer to Figure 5As shown, the valve core component 41 is connected to the first arm 31 away from one end of the third connecting part 311, the valve core component 41 drives the first arm 31 to rotate around the connection between the first connecting part 11 and the third connecting part 311, at the same time, the first arm 31 drives the first switch assembly 33, the first switch assembly 33 drives the second component 331, the second component 331 is disengaged from the locking state with the first component 21, so that the cover 2 is opened when the dishwashing powder is put into the containing cavity 13.
