[0002] In actual application, the detergent dispenser significantly improves the intelligence level and user experience of washing machines. Users no longer need to worry about the amount of detergent to be dispensed each time, nor do they need to worry about poor washing results or damage to clothes due to excessive or insufficient detergent. In addition, the intelligent dispensing function can also help reduce washing costs and improve washing efficiency, making it an ideal choice for modern family laundry.

[0003] When the existing washing machine dispenser is in use, the laundry detergent is discharged into the water delivery pipe through the delivery pipe, and finally the laundry detergent follows the water flow into the washing machine drum to remove stains and dirt from the clothes inside. However, in the absence of water, the residual laundry detergent will condense at the one-way valve in the pipe, and finally cause the pipe to be blocked, affecting the normal discharge of the laundry detergent. In addition, it is not easy to disassemble the one-way valve during unblocking and maintenance, thereby affecting the normal use of the washing machine dispenser. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5 As shown, the utility model is a liquid one-way valve anti-blocking assembly, comprising: an anti-blocking unit 1, a conveying unit 2 and a connecting unit 3, wherein the conveying unit 2 is clamped on the top of the anti-blocking unit 1, and the connecting unit 3 is fixedly connected to one end of the anti-blocking unit 1;

[0026] The anti-blocking unit 1 includes a protective shell 11, and the upper and lower end surfaces of the protective shell 11 are both provided with plug-in slots 12, one end surface of the protective shell 11 is symmetrically provided with a second plug-in hole 15, one end surface of the protective shell 11 is provided with a threaded hole 14 at the edge of the second plug-in hole 15, one end surface of the protective shell 11 is symmetrically provided with a first plug-in hole 13 at the edge of the threaded hole 14, and both end surfaces inside the plug-in slot 12 are provided with wedge-shaped card slots 16;

[0027] The conveying unit 2 includes a plug-in block 28, a limited position slide 21 is symmetrically provided on the top surface of the plug-in block 28, a pull ring 22 is arranged at the center of the top surface of the plug-in block 28, a wedge-shaped locking block 24 is slidably clamped inside the limited position slide 21, a push plate 23 is fixedly connected to the top of the wedge-shaped locking block 24, a return spring 29 is fixedly connected to one end of the wedge-shaped locking block 24, an interface pipe 25 is arranged at the bottom of the plug-in block 28, a tensioning spring 27 is arranged inside one end of the interface pipe 25, and a one-way valve plate 26 is fixedly connected to one end of the tensioning spring 27.

[0028] The connecting unit 3 includes a plug-in frame 31, a connecting block 32, a fastening bolt 33 and a connecting pipe 34. The connecting block 32 is arranged on the outer surface of one end of the connecting pipe 34. The plug-in frame 31 is evenly arranged on the outer surface of the connecting block 32. The fastening bolt 33 is rotatably clamped on the outer surface of the connecting block 32.

[0029] The plug-in block 28 of the utility model is clamped at the upper and lower ends of the protective shell 11 through the plug-in groove 12, which can facilitate the quick connection and removal of the conveying unit 2 and the anti-blocking unit 1. The wedge-shaped locking block 24 is clamped with the inside of the plug-in groove 12 through the wedge-shaped clamping groove 16, and the plug-in block 28 can be quickly locked inside the plug-in groove 12. The fastening bolt 33 is threadedly connected to the protective shell 11 through the threaded hole 14, and one end of the connecting pipe 34 can be fixedly connected to the protective shell 11. The plug-in frame 31 is slidably plugged with one end face of the protective shell 11 through the first plug-in hole 13, which can limit the connection of one end of the connecting pipe 34. One end of the connecting pipe 34 is sleeved on the outer surface of the interface pipe 25 through the second plug-in hole 15, which can ensure that the laundry detergent is transported to the inside of the drain pipe.

[0030] The working principle of the utility model is as follows: when using the washing machine, the laundry detergent is added into the dispenser, and then the dispenser is started to transport the laundry detergent into the interface pipe 25 through the connecting pipe 34, and finally the one-way valve plate 26 is pushed to open, so that the laundry detergent flows into the drain pipe and follows the water flow into the washing machine drum. After long-term use, the residual laundry detergent will condense inside the interface pipe 25, thereby affecting the normal opening of the one-way valve plate 26 and the normal discharge of the laundry detergent. Therefore, when the interface pipe 25 is unblocked, the conveying unit 2 needs to be removed for cleaning and unblocking. When the conveying unit 2 is removed, the fastening bolt 33 is first rotated in the opposite direction to separate it from the threaded hole 14, and then the plug-in frame 31 is pulled to separate it from the first plug-in hole 13, and finally one end of the connecting pipe 34 is driven to separate from the interface pipe 25, and then the two sets of push plates 23 are pressed to slide close to each other, so that the push plates 23 drive the wedge-shaped locking block 24 to slide inside the limiting slide 21, and at the same time The reset spring 29 is squeezed to shrink until the wedge-shaped locking block 24 is separated from the wedge-shaped slot 16 on the inner surface of the plug-in slot 12, and then the pull ring 22 is pulled to drive the plug-in block 28 to disengage from the inside of the plug-in slot 12, and then the inside of the interface pipe 25 can be cleaned and dredged. After cleaning, the bottom of the plug-in block 28 is symmetrically plugged into the plug-in slot 12. At the same time, the edge of the plug-in slot 12 will squeeze the wedge-shaped locking block 24 to shrink and slide until the wedge-shaped locking block 24 is aligned with the one-way valve plate 26. The wedge-shaped locking block 24 will be engaged with the wedge-shaped slot 16 under the push of the reset spring 29, and then one end of the connecting pipe 34 is sleeved with the interface pipe 25 inside the second plug-in hole 15, and then the plug-in frame 31 is aligned and plugged with the first plug-in hole 13, and the fastening bolt 33 is threadedly connected with the threaded hole 14. Therefore, through the coordinated connection between the anti-blocking unit 1, the conveying unit 2 and the connecting unit 3, it is convenient to dredge, replace and repair the one-way valve inside the washing machine dispenser, thereby ensuring the normal use of the washing machine.

[0031] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
