With the development of artificial intelligence, higher and higher requirements are placed on the convenience and reliability of detergent dispensing. In terms of operational convenience, although there are smart dispensing washing machines on the market that can store a large amount of laundry detergent for multiple washing cycles at one time, which reduces the user's operating steps to some extent, users still need to go to the market in person to buy laundry detergents in bags, bottles and other packaging methods that are not uniform, and irregularly put the right amount of detergent into the detergent storage tank of the washing machine's inherent components. In other words, a bottle or a pack of laundry detergent still needs to be dispensed multiple times.

[0003] In addition, the current delivery device has a complex structure and many parts, and requires multiple sets of molds, resulting in high manufacturing costs; the replenishing liquid is stored and transported in plastic bottles and plastic cans, which consumes plastic and is not environmentally friendly.

As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0030] See also Figure 1-Figure 7 The embodiment of the present invention provides an automatic detergent dispensing device suitable for a soft packaging bag, and the automatic detergent dispensing device suitable for a soft packaging bag includes a liquid storage tank 11, a liquid replenishing device 22 and a liquid pump 12. The specific description of each component is as follows:

[0031] The liquid storage tank 11 is used to store detergent. The liquid replenishing device 22 is connected to the liquid storage tank 11 and is used to be connected to the storage device 18. The liquid replenishing device 22 is used to replenish the detergent stored in the storage device 18 into the liquid storage tank 11 to ensure that the amount of detergent in the liquid storage tank 11 is sufficient.

[0032] The liquid pump 12 is connected to the liquid storage tank 11 and is used to be connected to the laundry device. The liquid pump 12 is used to quantitatively extract the detergent in the liquid storage tank 11 into the laundry device. For example, the amount of detergent extracted can be controlled by controlling the extraction time of the liquid pump 12 (for example, 5 seconds each time). The laundry device can be specifically a washing machine.

[0033] In the embodiment of the present invention, the storage device 18 can be specifically a soft packaging bag. The storage device 18 includes a liquid outlet 19 and a cover 20 matched with the liquid outlet 19. A hanging hole 21 is formed on the storage device 18.

[0034] By applying the technical solution of the present invention, detergent can be automatically added to the liquid storage tank 11 through the liquid replenishing device 22. The user only needs to connect the liquid replenishing device 22 to the storage device 18, and there is no need to add detergent multiple times, which is simple to operate. The detergent can be quantitatively extracted by the liquid pump 12, so that the amount of detergent can be accurately controlled. At the same time, the automatic detergent delivery device is suitable for soft packaging bags, which have low production costs and are easy to transport and store. The automatic detergent delivery device has a simple structure and low construction cost.

[0035] Furthermore, the liquid replenishing device 22 includes a liquid level control unit 13, a liquid adding probe 14, a cathode probe 16, a liquid level alarm probe 15, a solenoid valve 9, a front conduit 8, a rear conduit 10 and a liquid level alarm 1. The liquid level control unit 13 can be specifically a control chip such as a microprocessor (MCU).

[0036] The liquid level control unit 13 is respectively connected to the liquid adding probe 14, the negative electrode probe 16, the liquid level alarm probe 15, the liquid level alarm 1 and the solenoid valve 9. The solenoid valve 9 is connected to the storage device 18 through the front conduit 8, and the solenoid valve 9 is connected to the liquid storage tank 11 through the rear conduit 10. The liquid adding probe 14, the negative electrode probe 16 and the liquid level alarm probe are all extended into the liquid storage tank 11.

[0037] Furthermore, the length of the liquid adding probe 14 extending into the liquid storage tank 11 is less than the length of the negative electrode probe 16 extending into the liquid storage tank 11. The length of the liquid level alarm probe 15 extending into the liquid storage tank 11 is equal to the length of the negative electrode probe 16 extending into the liquid storage tank 11.

[0038] Furthermore, a threaded joint 7 is provided at one end of the front conduit 8 , and the front conduit 8 is connected to the opening of the storage device 18 via the threaded joint 7 .

[0039] Furthermore, the automatic detergent dispensing device further comprises a liquid extraction pipe 17 and a liquid outlet pipe 3. The liquid extraction pump 12 is connected to the liquid storage tank 11 via the liquid extraction pipe 17, and the liquid extraction pump 12 is connected to the laundry device via the liquid outlet pipe 3.

[0040] Furthermore, the automatic detergent dispensing device further comprises a liquid discharge control switch 2, which is connected to the liquid pump 12 and is used to control the start of the liquid pump 12. That is, after the user presses the liquid discharge control switch 2, the liquid pump 12 extracts a fixed amount of detergent into the laundry device.

[0041] Furthermore, the automatic detergent dispensing device further comprises a back plate 6 . The liquid storage tank 11 , the liquid replenishing device 22 and the liquid pump 12 are all mounted on the back plate 6 .

[0042] Furthermore, the automatic detergent dispensing device further comprises a hook 5, which is disposed on the back plate 6. Accordingly, the storage device 18 comprises a hanging hole 21, through which the hook 5 hangs the storage device 18.

[0043] Furthermore, the automatic detergent dispensing device also includes a housing 4 , and the liquid level alarm 1 and the liquid outlet control switch 2 are both arranged on the outside of the housing 4 .

[0044] See also Figure 5-Figure 7 , the working principle of the present invention is as follows:

[0045] like Figure 5As shown, when there is no liquid in the liquid storage tank 11, the liquid adding probe 14 and the negative electrode probe 16 are in a disconnected state, and the liquid level control unit 13 controls the solenoid valve 9 to be in a connected state; at the same time, the liquid level alarm probe 15 and the negative electrode probe 16 are in a disconnected state, and the liquid level control unit 13 controls the liquid level alarm 1 to alarm. At this time, the cover 20 on the liquid outlet 19 of the storage device 18 is unscrewed, and the liquid outlet 19 is tightened to the threaded joint 7, with the liquid outlet 19 facing downward, and the hanging hole 21 is hung on the hook 5. At this time, the liquid in the storage device 18 flows into the liquid storage tank 11 through the front conduit 8, the solenoid valve 9, and the rear conduit 10 due to gravity, and the liquid level in the liquid storage tank 11 gradually rises.

[0046] like Figure 6 As shown, when the liquid level continues to rise, when the liquid level alarm probe 15 and the negative electrode probe 16 contact the liquid at the same time, the circuit is connected, the liquid level control unit 13 controls the liquid level alarm 11 to stop the alarm, and the liquid level continues to rise.

[0047] like Figure 7 As shown, when the liquid level continues to rise, the liquid adding probe 14 and the cathode probe 16 simultaneously contact the liquid, the circuit is connected, and the liquid level control unit 13 controls the electromagnetic valve 9 to close. At this time, the liquid in the storage device 18 no longer flows out.

[0048] Furthermore, when the user turns on the liquid discharge control switch 2, the liquid pump 12 works to deliver the detergent in the liquid storage tank 11 to the laundry machine through the liquid discharge pipe 3. At this time, the liquid level in the liquid storage tank 11 gradually decreases until the liquid adding probe 14 cannot touch the liquid, the circuit is disconnected, the liquid level control unit 13 controls the solenoid valve 9 to connect, and the liquid in the storage device 18 flows into the liquid storage tank 11 again, and the liquid level rises until the liquid level control unit 13 controls the solenoid valve 9 to close. This cycle works in this way, and finally the liquid in the soft bag flows out completely. At this time, the liquid level in the liquid storage tank 11 continues to decrease until the liquid level alarm probe 15 cannot touch the liquid, the circuit is disconnected, and the liquid level control unit 13 controls the liquid level alarm 1 to alarm, prompting to change the storage device 18.
