[0001] This utility model belongs to the field of dispenser technology, specifically relating to a dispenser with a dual-throw independent dispensing cavity structure. Background Technology

[0002] Dishwashers typically use dispensers to automatically dispense detergent, making it easier and faster to add detergent and wash dishes. Existing patent CN222828557U discloses a dispensing system and a dishwasher using this system, including a housing with a liquid storage chamber; a liquid inlet connected to the liquid storage chamber on the side wall of the housing, and a dispensing port for dispensing liquid to the outside of the housing; a liquid pump located within the housing and adapted to draw liquid from the liquid storage chamber and pump it to the dispensing port; and a liquid inlet channel connected to the liquid storage chamber. However, the existing dispensing system only has a single dispensing chamber, making it unable to dispense multiple detergents and lacking versatility. Therefore, a dispenser with a dual-dispensing independent chamber structure is needed to overcome these difficulties. Summary of the Invention

[0003] This invention addresses the problems existing in the prior art by designing a distributor with a dual-injection independent dispensing chamber structure. This invention sets multiple temporary storage chambers in the main box and uses an electromagnetic drive device to drive the sealing valve core to switch the flow channel, so that each temporary storage chamber can dispense liquid to the main outlet, which has good versatility.

[0004] The objective of this invention is achieved through the following technical solution: a dispenser with a dual-dispensing independent dispensing chamber structure, comprising a main box body, a detergent powder placement trough within the main box body, and a sliding cover movable relative to the detergent powder placement trough on the main box body; a first dispensing port and a second dispensing port separated within the main box body, and a dispensing cover rotatably connected to the second dispensing port on the main box body; a first temporary storage chamber, a second temporary storage chamber, a first dispensing chamber, and a second dispensing chamber arranged side by side within the main box body; a sealing valve core component penetrating the first temporary storage chamber, the second temporary storage chamber, the first dispensing chamber, and the second dispensing chamber within the main box body; an electromagnetic drive device connected to the sealing valve core component within the main box body, which, when operating, drives the sealing valve core component to move along the temporary storage chamber within the main box body; an elastic component for automatic reset of the sealing valve core component is provided between the electromagnetic drive device and the sealing valve core component; and a main dispensing port for discharging liquid is provided on the main box body.

The third through hole is located between the first temporary storage chamber and the first liquid outlet chamber. A transition chamber is provided between the first liquid outlet chamber and the electromagnetic drive device, and the fourth through hole is located between the first liquid outlet chamber and the transition chamber. The sealing valve core in the main housing passes through the first through hole 17, the second through hole, the third through hole, and the fourth through hole in sequence. A second liquid outlet is provided between the second liquid outlet chamber and the main liquid outlet for connecting the two, and a first liquid outlet is provided between the transition chamber and the main liquid outlet for connecting the two.

[0007] Preferably, the sealing valve core is provided with a sealing head, a first sealing ring, a second sealing ring, and a third sealing ring in sequence along its axial direction. The end of the sealing valve core near the electromagnetic drive device is provided with an annular sealing portion. The sealing head is disposed adjacent to the first through hole 17. The first sealing ring is disposed in the second liquid outlet chamber and can move relative to the second liquid outlet chamber. The second through hole and the third through hole are disposed opposite to each other, and the second sealing ring is disposed between the second through hole and the third through hole. The third through hole and the fourth through hole are disposed opposite to each other, and the third sealing ring is disposed between the third through hole and the fourth through hole. The annular sealing portion is disposed in the transition chamber and can move relative to the transition chamber.

[0008] Preferably, the outer contour of the sealing head is adapted to the outer contour of the first through hole 17; the outer diameter of the first sealing ring is larger than the outer diameter of the second through hole; the outer diameter of the second sealing ring is larger than the outer diameter of the second through hole, and the outer diameter of the second sealing ring is also larger than the outer diameter of the third through hole; the outer diameter of the third sealing ring is larger than the outer diameter of the third through hole, and the outer diameter of the third sealing ring is also larger than the outer diameter of the fourth through hole.

[0009] Preferably, the main box body is provided with a liquid inlet vent, and the liquid inlet vent is connected to the first self-inlet chamber and the second self-inlet chamber; the main box body is also provided with a liquid outlet vent adjacent to the liquid inlet vent, and the liquid outlet vent is connected to the main liquid outlet.

[0010] Preferably, the electromagnetic drive device is a solenoid valve, and the elastic component includes a pull rod, a tension spring, and a torsion member; one end of the pull rod is connected to the solenoid valve, and the other end of the pull rod is connected to a sealing valve core, the sealing valve core being integrally sleeved and installed on the pull rod; the main housing is provided with a bushing integrally formed therewith, the bushing being disposed on the outer layer of the pull rod and the sealing valve core; the torsion member is rotatably connected to the main housing, a tension spring is provided between the torsion member and the main housing, and the end of the torsion member abuts against the pull rod.

[0011] Preferably, the pull rod is provided with a hollow groove, and the end of the torsion member is provided with a contact point, which abuts against the inner wall of the hollow groove; one end of the tension spring is mounted on the torsion member, and the other end of the tension spring is mounted on the main box.

[0012] Preferably, the end of the sealing valve core is provided with a protective sleeve disposed adjacent to it, and the protective sleeve is installed between the sealing valve core and the pull rod; both ends of the protective sleeve are provided with protrusions, and the bushing is provided with grooves, with the protrusions of the protective sleeve disposed within the grooves of the bushing. By providing the protective sleeve and the bushing, it is convenient to limit and guide the pull rod and the sealing valve core, thereby making the direction of movement of the sealing valve core more precise.

[0013] By default, the electromagnetic drive device is in a de-energized state. The torsion member pushes the pull rod away from the solenoid valve under the action of the tension spring. At this time, the sealing head blocks the first through hole 17, the second through hole is blocked by the second sealing ring, and the third through hole is blocked by the third sealing ring. The first temporary storage chamber and the second temporary storage chamber are not connected to the main liquid outlet, so the detergent cannot be discharged at this time, and the operator can add new detergent. After the dishwasher door is opened, the dispenser is in a flat position. At this time, the first and second self-dispensing chambers expel air from the main compartment through the dispensing vent, allowing for the smooth dispensing of detergent. Open the dispensing cap and add the first type of detergent to the first dispensing port. The first detergent will flow into the first self-dispensing chamber and then enter the first temporary storage chamber through the first flow hole. The first temporary storage chamber and the first self-dispensing chamber can then store the first type of detergent. Similarly, add the second type of detergent to the second dispensing port. The second detergent will flow into the second self-dispensing chamber and then enter the second temporary storage chamber through the second flow hole. The second temporary storage chamber and the first self-dispensing chamber can then store the second type of detergent.

[0014] After the dishwasher door is closed, the dispenser is in an upright position, and the electromagnetic drive is switched to the energized state. The liquid outlet vent in the main chamber is connected to the main liquid outlet, which facilitates air return to the main chamber, thus making the detergent dispensing smoother. After the electromagnetic drive is energized and engaged, the pull rod drives the sealing valve core to move towards the electromagnetic valve. At this time, the pull rod overcomes the elasticity of the tension spring, and the tension spring is in a stretched state. At this time, the first through hole 17 and the third through hole are in the open state, and the second through hole and the fourth through hole are in the closed state. Then the second temporary storage chamber is connected to the second liquid outlet chamber, and the second type of detergent flows from the second liquid outlet chamber along the second liquid outlet to the main liquid outlet, so that the second type of detergent can be discharged smoothly. At this time, some of the first type of detergent will flow into the first outlet chamber, and the first type of detergent will be temporarily stored in the first outlet chamber and the first temporary storage chamber. When the electromagnetic drive device is de-energized again, the first outlet chamber and the transition chamber are connected, and the first type of detergent flows from the transition chamber along the first outlet to the main outlet. In this way, by switching the power on and off of the electromagnetic drive device, different types of detergent can be discharged from the corresponding first temporary storage chamber or second temporary storage chamber.

[0015] When the electromagnetic drive device is de-energized again, the first through hole 17, the second through hole, and the third through hole will return to their initial sealed state. This ensures that even if the dishwasher door is reopened, the liquid in the first and second self-filling chambers will not flow out of the dispenser, facilitating the user's next liquid refill. The dispenser of this invention is connected to the extraction device inside the dishwasher, allowing the extraction device to automatically extract detergent when the flow channel corresponding to the main liquid outlet is opened.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The main box of the present invention is provided with two independent first temporary storage chambers and second temporary storage chambers. The two chambers do not interfere with each other, so that two different types of detergents can be added to the dispenser, which is more versatile; 2. The sealing valve core is moved by the electromagnetic drive device to switch the conduction state between the first temporary storage chamber and the main liquid outlet, or to switch the conduction state between the second temporary storage chamber and the main liquid outlet, so that it is convenient to add detergent and the user experience is better.

[0031] The electromagnetic drive device 12 is a solenoid valve, and the elastic component 13 includes a pull rod 131, a tension spring 132, and a torsion member 133. One end of the pull rod 131 is connected to the solenoid valve, and the other end of the pull rod 131 is connected to the sealing valve core 11. The sealing valve core 11 is integrally sleeved on the pull rod 131. The main housing 1 is provided with a bushing 26 integrally formed therewith. The bushing 26 is located on the outer layer of the pull rod 131 and the sealing valve core 11. The torsion member 133 is rotatably connected to the main housing 1. A tension spring 132 is provided between the torsion member 133 and the main housing 1. The end of the torsion member 133 abuts against the pull rod 131. The pull rod 131 has a hollow groove 134, and the end of the torsion member 133 has a contact point 30, which abuts against the inner wall of the hollow groove 134. One end of the tension spring 132 is mounted on the torsion member 133, and the other end of the tension spring 132 is mounted on the main housing 1. The end of the sealing valve core 11 has a protective sleeve 27 arranged adjacent to it, and the protective sleeve 27 is installed between the sealing valve core 11 and the pull rod 131. Both ends of the protective sleeve 27 have protrusions, and the bushing 26 has a groove. The protrusions of the protective sleeve 27 are located in the groove of the bushing 26.

[0032] The specific operation process of this embodiment is as follows: In the default state, the electromagnetic drive device 12 is in the power-off state. The torsion member 133 pushes the pull rod 131 away from the solenoid valve under the action of the tension spring 132. At this time, the sealing head 111 blocks the first through hole 17, the second through hole 18 is blocked by the second sealing ring 112, and the third through hole 19 is blocked by the third sealing ring 113. The first temporary storage chamber 7 and the second temporary storage chamber 8 are not connected to the main liquid outlet 14, so the detergent cannot be discharged at this time, so the operator can add new detergent. After the dishwasher door is opened, the dispenser is in a flat position. At this time, the first self-dispensing chamber 15 and the second self-dispensing chamber 16 expel the air from the main body 1 through the liquid dispensing vent 24, so that the detergent can be dispensed smoothly. Open the liquid dispensing cover 6 and add the first type of detergent into the first liquid dispensing port 4. The first type of detergent will flow into the first self-dispensing chamber 15 and then enter the first temporary storage chamber 7 along the first flow hole 28. At this time, the first temporary storage chamber 7 and the first self-dispensing chamber 15 can store the first type of detergent. Similarly, add the second type of detergent into the second liquid dispensing port 5. The second type of detergent will flow into the second self-dispensing chamber 16 and then enter the second temporary storage chamber 8 along the second flow hole 29. At this time, the second temporary storage chamber 8 and the second self-dispensing chamber 16 can store the second type of detergent.

[0033] After the dishwasher door is closed, the dispenser is in an upright position, and the electromagnetic drive device 12 is switched to the energized state. The liquid outlet vent 25 in the main chamber 1 is connected to the main liquid outlet 14, which facilitates air return to the main chamber 1, thus making the detergent dispensing smoother. After the electromagnetic drive device 12 is energized and engaged, the pull rod 131 drives the sealing valve core 11 to move in the direction of the electromagnetic valve. At this time, the pull rod 131 overcomes the elastic force of the tension spring 132, and the tension spring 132 is in a stretched state. At this time, the first through hole 17 and the third through hole 19 are in the open state, and the second through hole 18 and the fourth through hole 20 are in the closed state. Then the second temporary storage chamber 8 is connected to the second liquid outlet chamber 10, and the second type of detergent flows from the second liquid outlet chamber 10 along the second liquid outlet 21 to the main liquid outlet 14, so that the second type of detergent can be discharged smoothly. At this time, some of the first type of detergent will flow into the first outlet chamber 9, and the first type of detergent will be temporarily stored in the first outlet chamber 9 and the first temporary storage chamber 7. When the electromagnetic drive device 12 is de-energized again, the first outlet chamber 9 and the transition chamber 23 are connected, and the first type of detergent flows from the transition chamber 23 along the first outlet 22 to the main outlet 14. In this way, by switching the power on and off of the electromagnetic drive device 12, different types of detergent can be discharged from the corresponding first temporary storage chamber 7 or second temporary storage chamber 8.

[0034] When the electromagnetic drive device 12 is de-energized again, the first through hole 17, the second through hole 18, and the third through hole 19 will return to their initial sealed state. This ensures that even if the dishwasher door is reopened, the liquid in the first self-filling chamber 15 and the second self-filling chamber 16 will not flow out of the dispenser, facilitating the user's next liquid replenishment. The dispenser of this invention is connected to the extraction device inside the dishwasher, allowing the extraction device to automatically extract detergent when the flow channel corresponding to the main liquid outlet 14 is opened.
