DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0028] The embodiments of the present application provide a new type of venturi liquid suction automatic dispenser, which can solve the defect that direct injection of washing liquid into the water path often leads to uneven distribution of the washing liquid in the inner cylinder, and further makes the stirring effect in the washing process poor, and it is difficult to form abundant and lasting foam.

[0029] Referring to Figures 1 to 5 As shown in the drawings, the embodiment of the present application provides a new type of Venturi liquid suction automatic dispenser, which comprises a shell 1, a flow channel plate 4, a pipeline system and a Venturi tube 5. One side of the shell 1 is provided with a solution cavity 2, and the other side is provided with a water tank 3. In addition, a cavity cover plate 21 is arranged on the top of the solution cavity 2, which is used to close the solution cavity 2 to prevent the solution from volatilizing or being contaminated from the outside. The flow channel plate 4 is arranged on the top of the shell 1, and a detergent flow path is further arranged on the flow channel plate 4. One end of the detergent flow path is in communication with the solution cavity 2, and the other end is in communication with the water tank 3, so as to ensure that the solution can flow along the predetermined path. The pipeline system is arranged on the shell 1, and the pipeline system is used to transport the solution in the solution cavity 2 to the water tank 3 through the detergent flow path. The Venturi tube 5 is arranged on the shell 1, and the Venturi tube 5 is in communication with the water tank 3. One end of the Venturi tube 5 is provided as a water outlet end, and the other end is provided as a water inlet end.

[0030] The Venturi tube 5 is a special pipeline structure, the cross section of which suddenly narrows at a certain section, and then gradually expands. When the water flow passes through the narrowed cross section, the flow rate increases, and the pressure decreases to form a negative pressure area. This negative pressure effect can automatically suck the solution in the water tank 3. After the water inlet of the Venturi tube 5, the solution is fully mixed with the water to form abundant and lasting foam, which finally enters the inner barrel of the washing machine from the water outlet end, thereby improving the washing effect of the clothes.

[0031] In the present application, a one-way valve 50 is further connected between the Venturi tube 5 and the water tank 3. When the water inlet of the Venturi tube 5, the pipeline pressure increases, and when the pressure reaches the water pressure that opens the one-way valve 50, the one-way valve 50 is opened to release the water pressure in the waterway, thereby protecting the waterway.

[0032] In the present application, the solution cavity 2 is provided with at least two cavities, and the two cavities are respectively used to contain detergents and softening agents. A pressure sensor 20 is arranged in each cavity to accurately control the solution dispensing amount in the two cavities. In addition, each cavity is correspondingly connected with a detergent flow path to avoid mixing and cross contamination of the two solutions. The pipeline system comprises at least two pipeline units, and each pipeline unit is used to transport the solution in any cavity to the water tank 3 through the detergent flow path. Therefore, by corresponding each cavity with a detergent flow path and a pipeline unit, the dispensing amount, dispensing time and dispensing sequence of the detergents and softening agents can be independently controlled, thereby meeting the needs of different washing programs.

[0033] In the present application, the pipeline unit is provided and includes a piston pump 60 and a connecting pipe 63. The piston pump 60 is installed on the shell 1, and the piston pump 60 is provided with a liquid suction pipe and a liquid discharge pipe 62. The lotion flow path includes a liquid suction path 70 and a liquid discharge path 71. The liquid suction pipe is connected to the liquid suction path 70, and the liquid discharge pipe 62 is connected to the liquid discharge path 71. A liquid discharge port 72 is provided on the liquid discharge path 71 and is in communication with the sink 3. Then one end of the connecting pipe 63 is connected with a suction pipe 61, and the other end is in communication with the liquid suction path 70. The liquid suction pipe is in communication with the solution cavity 2.

[0034] The piston pump 60 is started, and the detergent and the softener in the cavity are transmitted from the liquid suction pipe to the connecting pipe 63, and then further from the liquid suction path 70 into the liquid suction pipe, and then discharged from the liquid discharge path 71 into the liquid discharge path 71, and finally from the liquid discharge port 72 into the sink 3. No manual intervention is required during the process, which greatly improves the automation degree of the washing process and saves manpower and time. By adjusting the pumping speed and pumping amount of the piston pump 60, the precise control of the amount of detergent and softener can be realized. This ensures that the ratio of detergent and softener in each washing program is consistent, thereby improving the washing effect.

[0035] In the present application, a water flow path 8 is further provided on the flow channel plate 4. One end of the water flow path 8 is provided with a water inlet, and the water inlet is connected with a water inlet pipe 800. The other end of the water flow path 8 is in communication with the sink 3. The bottom of the sink 3 is further connected with a cleaning through hole 9. In use, water is transported into the water flow path 8 through the water inlet pipe 800, and finally flows into the sink 3 to flush the sink 3. The flushing water can flow into the inner barrel of the washing machine through the cleaning through hole 9.

[0036] In addition, the water flow path 8 includes a first flow channel 80, a second flow channel 81 and a third flow channel 82. The water inlet is provided on the first flow channel 80. The second flow channel 81 is in communication with the sink 3. The third flow channel 82 is provided with a water outlet 820. The water outlet 820 is further connected with a water outlet pipe 821. The paths of the water flow path are clear in division of labor, and different paths have different functions and do not interfere with each other. The excess water flowing out of the water flow path 8 from the water outlet pipe 821 is discharged into the inner barrel of the washing machine, avoiding resource waste.

[0037] In the present application, the cover plate 40 is connected to the flow channel plate 4. The connection of the cover plate 40 and the flow channel plate 4 can form a closed cavity or channel, which helps to prevent solution leakage and ensure that the solution in the flow channel flows along the predetermined path. At the same time, the cover plate 40 can also isolate the flow channel plate 4 from the external environment, protecting the flow channel plate 4 from interference and damage from external factors.

[0038] In the present application, the flow channel plate 4 is further provided with an air inlet 41 and an air outlet 42. The air inlet 41 is connected with a gas-permeable tube 410, and the air outlet 42 is in communication with the water tank 3. The shell 1 is further provided with an air outlet 43. The gas-permeable tube 410 connected with the air inlet 41 can introduce external air to the flow channel plate 4 and the detergent flow path. This helps to keep the air in the detergent flow path fresh and avoid odor or bacterial growth due to lack of air circulation after long-term use. In addition, during the process of the detergent or softener being pumped out by the piston pump 60 and entering the water tank 3 through the detergent flow path, a certain pressure change may occur. By providing the air inlet 41 and the air outlet 42, the pressure inside and outside the water tank 3 can be balanced to prevent leakage or.
