Description

Technical Field

[0002] The pipeline machine has a built-in water tank for temporarily storing a certain volume of clean water so that users can get enough water when they receive water. The common way to get water on the market is to directly insert a water pipe into the water and pump the water into the next component through the action of a pump. However, after the pump stops working, the water in the water pipe will flow back to the water tank under the action of gravity, causing the water pipe to be filled with air. Therefore, in the next water collection process, the air in the water pipe needs to be exhausted before water can be supplied, which reduces the water collection efficiency and the user's water collection experience is poor. Summary of the invention

Figure 2The schematic diagram of the internal cross section of the water intake pipe in the water tank assembly provided in one embodiment of the present application. The water tank assembly provided in one embodiment of the present application includes a water tank body 100, a water intake pipe 200 and a check piece 300; the water tank body 100 has a water storage chamber 110; the water intake pipe 200 is partially accommodated in the water storage chamber 110, and the water inlet end 210 of the water intake pipe 200 extends to the bottom of the water storage chamber 110, and the water outlet end 220 of the water intake pipe 200 extends out of the water tank body 100, and a water pump is provided on the water intake pipe 200 to pump the water in the water storage chamber 110 to the water outlet end 220 of the water intake pipe 200 through the water inlet end 210 of the water intake pipe 200; the check piece 300 is installed in the water intake pipe 200 and is located on the side of the water pump close to the water inlet end 210, and the check piece 300 is used to limit the water flow in the water intake pipe 200 from flowing out through the water inlet end 210.

[0037] Specifically, in the present application, a check member 300 is provided in the water intake pipe 200, and the check member 300 is located on the side of the water pump close to the water inlet end 210. Thus, after the water pump stops working, the check member 300 can limit the water flow in the water intake pipe 200 from flowing out through the water inlet end 210, thereby preventing the water flow in the water intake pipe 200 from flowing back into the water tank body 100 under the action of gravity, thereby avoiding the presence of air in the water intake pipe 200, so that in the next water intake process, there is no need to exhaust the air in the water intake pipe 200 before water is supplied, thereby improving the water intake efficiency and user experience, and at the same time effectively preventing the water hammer effect from damaging the pipes and water pump in the water tank assembly.

[0038] Furthermore, the water tank body 100 further includes a box body 140 and a cover body 150 that are detachably connected. When the cover body 150 is connected to the box body 140 , a water storage chamber 110 is enclosed.

[0039] See also Figure 2 and Figure 3 , Figure 3 A schematic cross-sectional view of a check member in a water tank assembly provided in one embodiment of the present application. In one embodiment, the check member 300 includes a housing 310 and a blocking member 340, the housing 310 is connected to the inner wall of the water intake pipe 200, the housing 310 has a water outlet channel 333 in communication with the water storage chamber 110, the blocking member 340 is disposed in the water outlet channel 333, and the blocking member 340 is configured to move from a first position blocking the water outlet channel 333 to a second position opening the water outlet channel 333 under the action of a water pump.

[0040] Specifically, the second position is located above the first position. When the blocking member 340 is in the first position, the water outlet channel 333 can be blocked, so that the water inlet pipe and the water storage chamber 110 are blocked; when the blocking member 340 is in the second position, the water outlet channel 333 is connected, so that the water inlet pipe and the water storage chamber 110 are connected. When the water pump works to generate suction force, the blocking member 340 moves upward from the first position to the second position under the action of the water pump, so that the water outlet channel 333 is connected to take water.

[0041] See also Figure 2 and Figure 3 In one embodiment, the check member 300 further includes an elastic member 350, which is located between the housing 310 and the blocking member 340. The elastic member 350 is used to apply a thrust to the blocking member 340 toward the first position, so that after the water pump stops working, the blocking member 340 stably moves from the second position to the first position under the thrust of the elastic member 350, and stabilizes at the first position, thereby stably limiting the water flow in the water intake pipe 200 from flowing back through the water inlet end 210. Preferably, the elastic member 350 is a spring.

[0042] See also Figure 2 and Figure 3 In one embodiment, the blocking member 340 includes a blocking block 341 and a first sealing ring 342. The first sealing ring 342 is sleeved on the blocking block 341 and connected to the blocking block 341. When the blocking member 340 is in the first position, the first sealing ring 342 elastically abuts against the inner wall of the shell 310 throughout the entire circumference to block the water outlet channel 333.

[0043] Specifically, the first sealing ring 342 can be deformed. After the water pump stops working, the sealing member 340 moves to the first position under the action of the elastic member 350, and abuts against the inner wall of the shell 310 through the entire circumference of the first sealing ring 342, thereby stabilizing the gap between the sealing member 340 and the shell 310 to improve the sealing performance of the water outlet channel 333 and prevent the water flow in the water intake pipe 200 from flowing back into the water tank body 100 under the action of gravity.

[0044] See also Figure 2 , Figure 3 and Figure 4 , Figure 4 A partial exploded schematic diagram of a backstop in a water tank assembly provided in an embodiment of the present application. In one embodiment, a circumferentially arranged abutment surface 331 is provided in the housing 310, the abutment surface 331 is used to abut against the first sealing ring 342, and in the direction from the second position to the first position, the distance between the abutment surface 331 and the axis of the water intake pipe 200 gradually decreases.

[0045] Specifically, the abutting surface 331 is an inclined surface. When the first sealing ring 342 abuts against the abutting surface 331, under the thrust of the elastic member 350, the first sealing ring 342 is subjected to increasing extrusion force, causing the first sealing ring 342 to be deformed more and more, thereby achieving a better sealing effect.

[0046] The cross-sectional area of ​​the first sealing ring 342 in its radial direction is circular, so that when the first sealing ring 342 abuts against the abutting surface 331 to be deformed, a partial area of ​​the first sealing ring 342 can fit against the abutting surface 331, thereby ensuring the sealing effect.

[0047] Furthermore, the side wall of the blocking block 341 has a first mounting groove 344 , the first sealing ring 342 is installed in the first mounting groove 344 and partially extends out of the first mounting groove 344 , and the inner contour of the first mounting groove 344 is adapted to the outer contour of the first sealing ring 342 .

[0048] See also Figure 2 , Figure 3 and Figure 4 In one embodiment, a guide hole 321 is provided on the shell 310, and a guide rod 343 is protruded on the side of the blocking member 340 facing the second position. The guide rod 343 is inserted into the guide hole 321 and is slidably connected to the hole wall of the guide hole 321 to guide the movement of the blocking member 340 between the first position and the second position.

[0049] Specifically, the guide rod 343 is connected to the side of the blocking block 341 facing the second position, and the guide rod 343 is plugged and matched with the guide hole 321, so that the blocking member 340 moves accurately toward the second position under the action of the water pump, and moves accurately toward the first position under the action of the elastic member 350, thereby improving the reliability of the water tank assembly. The guide rod 343 is inserted into the elastic member 350.

[0050] Furthermore, a boss 345 is provided on the blocking block 341, and the boss 345 is arranged around the circumference of the water intake pipe 200, and the boss 345 is arranged on the outside of the elastic member 350 to limit the displacement of the elastic member 350 relative to the blocking block 341, so that the elastic member 350 applies a stable thrust toward the second position to the blocking member 340.

[0051] See also Figure 2 , Figure 3 and Figure 4In one embodiment, the housing 310 includes an inner housing 320 and an outer housing 330, the outer housing 330 is connected to the inner wall of the water intake pipe 200, the abutment surface 331 is arranged on the outer housing 330, the inner housing 320 is inserted into the outer housing 330 and is clamped with the outer housing 330, the end of the elastic member 350 away from the blocking block 341 is connected to the inner housing 320, and the guide hole 321 is arranged on the inner housing 320. The separate arrangement of the inner housing 320 and the outer housing 330 facilitates the installation of the blocking member 340 and the elastic member 350, thereby improving the assembly efficiency. Among them, a ring-shaped protrusion 322 is also arranged on one side of the first position of the inner housing 320, and the elastic member 350 is sleeved on the protrusion 322 for guidance.

[0052] Furthermore, the outer wall of the inner shell 320 has a locking protrusion 323, and the inner wall of the outer shell 330 has a locking groove 334, and the locking protrusion 323 and the locking groove 334 are engaged with each other, so that the inner shell 320 is connected to the outer shell 330. The locking groove 334 is arranged at the end of the outer shell 330 away from the abutting surface 331, so as to facilitate deformation, so that the locking protrusion 323 extends into the locking groove 334 and abuts against the groove wall of the locking groove 334, so as to limit the inner shell 320 from coming out relative to the outer shell 330. The locking protrusion 323 and the locking groove 334 are arranged around the entire circumference of the water intake pipe 200.

[0053] Furthermore, a stopper 324 is further provided on the inner shell 320, and the stopper 324 abuts against the end surface of the outer shell 330. Preferably, the stopper 324 is provided around the entire circumference of the guide rod 343.

[0054] The inner side of the outer shell 330 is also provided with a matching groove 335, and one end of the inner shell 320 away from the stopper 324 is plugged into the matching groove 335, thereby improving the stability of the connection between the inner shell 320 and the outer shell 330. Preferably, the matching groove 335 is arranged around the entire circumference of the water intake pipe 200.

[0055] See also Figure 2 , Figure 3 and Figure 4 In one embodiment, the check member 300 also includes a second sealing ring 360, which is sleeved on the outer shell 330 and connected to the outer shell 330, and the second sealing ring 360 abuts against the inner wall of the water intake pipe 200 to seal the gap between the inner wall of the water intake pipe 200 and the outer wall of the outer shell 330, thereby preventing water from flowing through the gap between the inner wall of the water intake pipe 200 and the outer wall of the outer shell 330, so as to ensure the reliability of the check member 300 in limiting the water flow in the water intake pipe 200 from flowing back into the water tank body 100.

[0056] Furthermore, the outer wall of the housing 330 is provided with a second mounting groove 332, and the second sealing ring 360 is mounted in the second mounting groove 332 and partially extends out of the second mounting groove 332, and the inner contour of the second mounting groove 332 is adapted to the outer contour of the second sealing ring 360. The cross-sectional area of ​​the second sealing ring 360 in its radial direction is circular.

[0057] See also Figure 1 and Figure 2 In one embodiment, the check member 300 is located at the bottom of the water storage chamber 110, thereby shortening the distance between the first position and the water inlet end 210 of the water intake pipe 200, thereby reducing the gravity of the water between the first position and the water inlet end 210 of the water intake pipe 200, and thus when the blocking member 340 is located at the first position, the possibility of the water between the first position and the water inlet end 210 of the water intake pipe 200 flowing back to the water tank body 100 is reduced.

[0058] See also Figure 1 , Figure 2 and Figure 5 , Figure 5 A schematic diagram of the structure of a water intake pipe 200 in a water tank assembly provided in one embodiment of the present application. In one embodiment, a gap is provided between the end surface of the water intake pipe 200 close to the water inlet end 210 and the bottom wall of the water tank body 100 to form a water inlet 230, so that when the water level in the water tank body 100 drops to the bottom of the water storage chamber 110, the water in the water storage chamber 110 can still enter the water intake pipe 200 under the action of the water pump and be pumped out of the water tank body 100, thereby improving the utilization rate of the water in the water tank body 100.

[0059] Furthermore, a notch 240 is provided on one side of the pipe wall of the water intake pipe 200 near the water inlet end 210, so as to increase the size of the water inlet 230 in the gravity direction and improve the water intake efficiency. The number of the notches 240 is at least two, and they are evenly spaced around the circumference of the water intake pipe 200. Preferably, the number of the notches 240 is three.

[0060] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 , Figure 6 A top view of a water tank assembly in an embodiment of the present application. In one embodiment, the entire circumferential end surface of the water intake pipe 200 close to the water inlet end 210 has a gap with the bottom wall of the water tank body 100, and a baffle 120 is provided on the bottom wall of the water tank body 100. The baffle 120 is arranged on one side of the water intake pipe 200, and the baffle 120 is used to abut against the water intake pipe 200 to limit the deflection of the water intake pipe 200 relative to the bottom wall of the water tank body 100.

[0061] Specifically, the lower end of the water intake pipe 200 is suspended, and the baffle 120 is arranged to prevent the water tank assembly from tilting during transportation, installation and use, resulting in failure to fill water, thereby improving the reliability of the water tank assembly.

[0062] Furthermore, the number of baffles 120 is at least three, and they are evenly spaced around the circumference of the water intake pipe 200 to stably limit the side of the water intake pipe 200 close to the water inlet end 210, and facilitate the passage of water through the gaps between adjacent baffles 120. Preferably, the baffles 120 are arc-shaped and fit the outer contour of the water intake pipe 200.

[0063] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment, a groove 130 is provided on the bottom wall of the water tank body 100. The groove 130 is recessed downward relative to the bottom wall of the water tank body 100. The groove 130 is located below the water inlet 230 of the water intake pipe 200. Therefore, when there is insufficient clean water in the water tank body 100, the clean water will flow to the groove 130 and be sucked up by the water intake pipe 200, thereby facilitating the drainage of the water in the water storage chamber 110 and improving the utilization rate of the water in the water tank body 100.

[0064] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment, the bottom wall of the groove 130 has a drainage hole 134 connected to the water storage chamber 110, and the drainage hole 134 is spaced apart relative to the water intake pipe 200. The water tank assembly also includes a valve cover, which is detachably connected to the water tank body 100 and is used to block the drainage hole 134.

[0065] Specifically, when the purified water in the water tank body 100 needs to be replaced, the valve cover can be removed relative to the water tank body 100 , so that the purified water in the water storage chamber 110 can be discharged through the drainage hole 134 .

[0066] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 In one embodiment, in a direction perpendicular to the arrangement direction of the water inlet 230 and the drainage hole 134, the groove 130 has first side walls 131 arranged opposite to each other. In the arrangement direction of the water inlet 230 and the drainage hole 134, the distance between the two first side walls 131 gradually decreases, and the height of the bottom wall of the groove 130 gradually decreases, thereby forming a convergent type, which facilitates the water in the groove 130 to flow out toward the drainage hole 134.

[0067] Furthermore, one end of the two first side walls 131 away from the water intake pipe 200 is connected to the hole wall of the drainage hole 134, so as to facilitate the water in the groove 130 to flow out toward the drainage hole 134. The groove 130 further includes an arcuate wall 133, which is connected to one end of the two first side walls 131 away from the drainage hole 134 and matches the contour of the drainage hole 134. In the direction of gravity, the arcuate wall 133 is located outside the outer wall of the water intake pipe 200.

[0068] See also Figure 1 , Figure 2 , Figure 3 and Figure 6 The present application also provides a drinking water device, including the above-mentioned water tank assembly. By arranging a check piece 300 in the water intake pipe 200, and the check piece 300 is located on the side of the water pump close to the water inlet end 210, after the water pump stops working, the check piece 300 can limit the water flow in the water intake pipe 200 from flowing out through the water inlet end 210, thereby preventing the water flow in the water intake pipe 200 from flowing back into the water tank body 100 under the action of gravity, thereby preventing the water intake pipe 200 from being filled with air, so that in the next water intake process, the air in the water intake pipe 200 does not need to be discharged before water is supplied, thereby improving the water intake efficiency and user experience of the drinking water device.
