Description

Technical Field

[0001] This utility model belongs to the field of valve technology, specifically relating to a parallel structure push rod valve water injection assembly and system. Background Technology

[0002] Existing smart home cleaning robots, when entering the base station to replenish water and clean the bottom mop, fill the clean water tank through a water inlet on the panel. From the clean water tank, water splits into pipes A and B. Pipe A delivers water to clean the mop, while pipe B is used for daily floor cleaning. During this process, because pipe A is continuously cleaning the mop, when the water level in the clean water tank drops to a certain level, the water inlet must continue to fill the clean water tank. After filling, water filling stops, and then the clean water in the clean water tank is transferred to pipe A again. This process is repeated, meaning that water needs to be added multiple times when cleaning the mop. This increases the number of times the device works internally, resulting in low work efficiency and a complex piping distribution. Utility Model Content

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] This embodiment provides a parallel-structured push-rod valve water injection system for use in a smart home cleaning robot. It includes a push-rod valve water injection assembly, as shown in the reference... Figures 1 to 5 As shown, the push-rod valve water injection assembly includes a water injection system panel 1, a valve core assembly 2, and a cover 3.

[0033] Furthermore, the water injection system panel 1 and the upper cover 3 are welded and fixed together, and the valve core assembly 2 is disposed between the water injection system panel 1 and the upper cover 3. The water injection system panel 1 is provided with a first water inlet pipe 11 and a second water inlet pipe 12. The first water inlet pipe 11 has a first water inlet, and the second water inlet pipe 12 has a second water inlet. The valve core assembly 2 is used to open or close the flow channel, combined with… Figure 1 and Figure 3 As shown, the valve core assembly 2 includes a first valve core assembly 21 and a second valve core assembly 22 arranged side by side. A first water inlet pipe 11 is connected to the first valve core assembly 21, and a second water inlet pipe 12 is connected to the second valve core assembly 22. The cover 3 is provided with a first water outlet pipe 31 and a second water outlet pipe 32. One end of the first water outlet pipe 31 is connected to the first water inlet pipe 11, and the other end is connected to the clean water tank. When the flow channel is open, clean water flows from the first water inlet pipe 11 into the area of ​​the first valve core assembly 21, and flows from the first water outlet pipe 31 into the clean water tank of the smart home cleaning robot. One end of the second water outlet pipe 32 is connected to the second water inlet pipe 12, and the other end outputs clean water for cleaning the cleaning system of the smart home cleaning robot, such as the rags. When the flow channel is open, clean water flows from the second water inlet pipe 12 into the second valve core assembly 22, and flows out from the second water outlet pipe 32.

[0034] Valve core assembly 2 includes a push rod, a sealing ring, and an elastic element; the first valve core assembly 21 includes a first push rod 211, a first sealing ring 212, and a first elastic element 213, with the first elastic element 213 located between the first push rod 211 and the cover 3, and the first sealing ring 212 snapped onto the first push rod 211; the second valve core assembly 22 includes a second push rod 221, a second sealing ring 222, and a second elastic element 223, with the second elastic element 223 located between the second push rod 221 and the cover 3, and the second sealing ring 222 snapped onto the second push rod 221. During operation, air pressure or water pressure can be used, or a rigid component can be used to push the push rod open through face-to-face contact to achieve the water injection function. When the push rod is under pressure, the elastic element is in a compressed state, and the fluid flows down along the gap between the valve body assembly 2 and the cover 3; when water injection stops, the elastic element drives the push rod to reset, and the sealing ring on the push rod acts as a seal, cutting off the flow path and preventing liquid leakage.

[0035] Furthermore, the water injection system panel 1 is provided with an inclined surface 13, on which the first sealing ring 212 and the second sealing ring 222 abut against the inclined surface 13. The inclined surface 13 can seal and limit the first sealing ring 212 and the second sealing ring 222, achieving a good sealing effect and effectively preventing liquid leakage.

[0036] Combination Figure 4 and Figure 5 As shown, the first push rod 211 has a first end 2112 and a second end 2113. The first end 2112 is inserted into the first water inlet pipe 11, and the second end 2113 is inserted into the cover 3. The first end has a first notch 2111, and the second end 2113 has multiple through holes 2114 that can communicate with the first notch 2111. More specifically, liquid enters from the first inlet and flows into the first notch 2111, then flows into the area of ​​the first valve core assembly 21, and finally flows out from the first outlet pipe 31 along the guide post 6 and the lower limit post 34. Similarly, the second push rod 221 has a third end and a fourth end. The third end is inserted into the second inlet pipe 12, and the fourth end is inserted into the cover 3. The third end has a second notch 2211, and the fourth end has multiple through holes that can communicate with the second notch 2211. Liquid enters from the second inlet and flows into the second notch 2211, then flows into the area of ​​the second valve core assembly 22, and finally flows out from the second outlet pipe 32 along the guide post 6 and the lower limit post 34. The design of the first push rod 211 and the second push rod 221 ensures sufficient flow.

[0037] Reference Figure 4As shown, the water injection system panel 1 has an upper limit stop 14 to prevent the push rod from moving upwards beyond the movement area, thus preventing the push rod from being pushed out. The cover 3 has a lower limit stop 33 to prevent the push rod from moving downwards beyond the movement area, thus preventing the push rod from being pushed to the bottom and blocking the water outlet pipe, causing a decrease in flow. In addition, the cover 3 has a limit post 34 to prevent the push rod from moving downwards beyond the movement area, thus preventing the push rod from being pushed to the bottom and blocking the water outlet pipe. The cover 3 has a guide post 6, which is used to guide the push rod to prevent it from deviating to the left or right. The lower limit stop 33 and the guide post 6 are integrally set, and the lower limit stop 33 is located below the guide post. The terms "upper" and "lower" here refer to... Figure 4 The up and down directions shown on the paper.

[0038] Furthermore, the push rod has a first groove 4, the cover 3 has a second groove 5, one end of the elastic element is fixed in the first groove 4, and the other end is fixed in the second groove 5. This ensures that the elastic element can be in the center position and will not wobble. In this embodiment, the elastic element is specifically a spring.

[0039] In this embodiment, the push rod valve water injection assembly is assembled by first fitting the sealing ring onto the push rod, then fixing one end of the spring in the first groove 4 and the other end in the second groove 5, then placing the push rod onto the cover 3 with the spring, thus assembling the valve core assembly 2 and the cover 3. Next, the cover 3 and the water injection system panel 1 are assembled and welded together. Finally, the functionality of the inlet and outlet ends is tested. When the push-rod valve water injection assembly is working, positive pressure is first applied to the two inlet pipes of the water injection system panel (air pressure or water pressure can be used, or a rigid component can be used to push the push rod through face-to-face contact), causing the entire valve core assembly to move downwards. Liquid flows through the gaps to the first outlet pipe 31 and the second outlet pipe 32. The first outlet pipe 31 outputs clean water to the clean water tank, and the second outlet pipe 32 outputs clean water for use in the cleaning system, such as for cleaning rags. When rags need to be cleaned, clean water only needs to be continuously injected into the second inlet pipe 12, which improves work efficiency. Unlike the existing technology, it is not necessary to fill the clean water tank first and then output clean water to the A pipe to clean the rags. When the water level in the clean water tank drops to a certain level, the cleaning of the rags is stopped, and water is continuously injected into the clean water tank, which is repeated, resulting in lower work efficiency.

[0040] The push-rod valve water injection assembly in this embodiment is equipped with two independent valve core assemblies to meet different water circuit usage requirements, saving space and reducing the complexity of downstream pipeline distribution and system operation.
