Description

Technical Field

[0001] This application relates to the field of drinking water equipment technology, and in particular to water tank components and drinking water equipment. Background Technology

[0002] A water dispenser used in conjunction with a water purifier can heat the purified water, satisfying the Chinese preference for hot water. To ensure a good user experience, most water dispensers on the market have a built-in water tank to temporarily store a certain volume of purified water, ensuring a sufficient supply for users. The water tank typically has an inlet hole, which is sealed by a float under buoyancy to limit water flow. In related technologies, when using a water dispenser with a high-flow-rate water purifier, a larger inlet hole diameter is generally used to address the frequent start-stop issue of the purifier's water pump. However, this increased inlet hole diameter leads to poor sealing performance when the float seals the inlet hole under buoyancy. Utility Model Content

[0003] Based on this, it is necessary to address the issue that in related technologies, when a pipeline water dispenser is paired with a high-flow water purifier, a larger inlet diameter is generally used to solve the problem of frequent start-stop of the water purifier's water pump. However, due to the increased inlet diameter, the existing float has poor sealing performance when sealing the inlet under buoyancy. Therefore, a water tank assembly is needed.

[0004] A water tank assembly, comprising:

[0005] The water tank body has a water storage cavity and a water inlet channel communicating with the water storage cavity;

[0006] A blocking element, wherein the blocking element is disposed within the water inlet channel and is movable between a first position blocking the water inlet channel and a second position opening the water inlet channel; and,

[0007] A floating component is disposed within the water storage chamber. The floating component includes a connecting rod and a float that are interconnected. The connecting rod is driven to the sealing component. The float is configured to move the connecting rod with the water level so that when the water level reaches a predetermined level, the sealing component is driven to the first position. The height of the float is lower than the height of the sealing component.

[0008] The aforementioned water tank assembly is installed inside the water storage chamber via a float. As the float moves with the water level, it drives a connecting rod to move. When the water level reaches a predetermined level, the connecting rod can drive the sealing component to move to the first position to stop the continued intake of water into the water storage chamber. Since the height of the float is lower than the height of the sealing component, the float can be completely submerged in water when the water tank is not full, thereby providing maximum buoyancy to the connecting rod. This allows the connecting rod to drive the sealing component to block the water inlet channel, thus improving the sealing performance.

[0009] In one embodiment, the connecting rod includes a first rod segment and a second rod segment connected to each other, the first rod segment being kinetically connected to the sealing member, and the second rod segment being located below the first rod segment and connected to the float.

[0010] In one embodiment, the first rod segment is parallel to the central axis of the float, and when the sealing member is in the first position, the first rod segment extends in the horizontal direction.

[0011] In one embodiment, the link further includes a third segment, through which the second segment is connected to the first segment, and the second segment is parallel to the first segment.

[0012] In one embodiment, the water tank assembly further includes a partition connected to the inner wall of the water inlet channel and dividing the water inlet channel into a first segment and a second segment. The second segment is located below the first segment. The sealing member is disposed in the second segment. The partition has a through hole. When the sealing member is in the first position, it blocks the through hole.

[0013] In one embodiment, the partition includes an annular plate and a boss. The outer side of the annular plate is connected to the inner wall of the water inlet channel, and the boss is connected to the inner side of the annular plate and protrudes toward the sealing member. The through hole is provided on the boss, and the outer contour area of ​​the boss gradually decreases in the direction from the first hole segment to the second hole segment.

[0014] In one embodiment, the sealing member is slidably connected to the inner wall of the second hole segment, and the sealing member has a water flow channel for communicating with the water inlet channel when the sealing member is in the second position.

[0015] In one embodiment, the top wall of the water tank body is provided with a water inlet connector, the water inlet connector defines the water inlet channel, and the end of the connecting rod away from the float is rotatably connected to the water inlet connector.

[0016] In one embodiment, at least a portion of the connecting rod is located below the water inlet channel and abuts against the sealing element.

[0017] This application also provides a drinking water device that can solve at least one of the above-mentioned technical problems.

[0018] A drinking water device includes the water tank assembly described above. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] See Figure 1 and Figure 2 , Figure 1 This is a partial structural schematic diagram of a water tank assembly provided in one embodiment of this application. Figure 2 This is a partial cross-sectional schematic diagram of a water tank assembly provided in an embodiment of this application. The water tank assembly provided in an embodiment of this application includes a water tank body, a sealing member 200, and a floating member 300. The water tank body has a water storage chamber and a water inlet channel 110 communicating with the water storage chamber. The sealing member 200 is disposed within the water inlet channel 110 and is movable between a first position blocking the water inlet channel 110 and a second position opening the water inlet channel 110. The floating member 300 is disposed within the water storage chamber and includes a connecting rod 310 and a float 320. The connecting rod 310 is tractively connected to the sealing member 200, and the float 320 is configured to move with the water level, causing the connecting rod 310 to move, so that when the water level reaches a predetermined level, the sealing member 200 is driven to the first position. The height of the float 320 is lower than the height of the sealing member 200.

[0031] Specifically, the water tank body has a water storage chamber and a water inlet channel 110. When the sealing member 200 is in the first position, it can block the water inlet channel 110 to stop water from continuing to enter the water storage chamber. When the sealing member 200 is in the second position, the water inlet channel 110 is open, and water can be replenished into the water storage chamber through the water inlet channel 110. The float 320 is installed in the water storage chamber. When the float 320 moves with the change of water level, it can drive the connecting rod 310 to move, so that when the water level reaches the predetermined water level, the connecting rod 310 can drive the sealing member 200 to move to the first position, blocking the water inlet channel 110 to stop water from continuing to enter the water storage chamber. Since the height of the float 320 is lower than the height of the sealing component 200, the float 320 can be completely submerged in water when the water tank body is not full. This provides maximum buoyancy to the connecting rod 310, so that the connecting rod 310 is transmitted to the sealing component 200 to block the water inlet channel 110, thereby improving the sealing performance of the water inlet channel 110.

[0032] When the water level in the storage chamber is low, the float 320 is at a lower height, and the sealing component 200 can move to the second position under the action of the connecting rod 310 or its own gravity to keep the water inlet channel 110 open. As the water replenishment process progresses, the water level gradually rises, and the float 320 moves with the water level, simultaneously driving the sealing component 200 to gradually move from the second position to the first position to block the water inlet channel 110.

[0033] Furthermore, the float 320 is a rotating body and has a closed cavity, which can improve the sensitivity of the float 320 to move with the water level.

[0034] See Figure 1 and Figure 2 In one embodiment, the connecting rod 310 includes a first rod segment 311 and a second rod segment 312 connected to each other. The first rod segment 311 is throttle-connected to the sealing member 200, and the second rod segment 312 is located below the first rod segment 311 and connected to the float 320.

[0035] Specifically, the float 320 is connected to the end of the second rod segment 312 away from the first rod segment 311. By positioning the second rod segment 312 below the first rod segment 311, there is sufficient distance between the float 320 and the end of the connecting rod 310 near the sealing member 200 to position the float 320. This ensures that the float 320 is located below the sealing member 200, guaranteeing that the float 320 is completely submerged in water when the water tank is not full, thereby providing maximum buoyancy to the connecting rod 310.

[0036] See Figure 1 and Figure 2 In one embodiment, the first rod segment 311 is parallel to the central axis of the float 320, and when the sealing member 200 is in the first position, the first rod segment 311 extends in the horizontal direction.

[0037] Specifically, when the sealing component 200 is in the first position, the central axis of the float 320 is parallel to the horizontal direction. That is, as long as the water in the tank body is above the top of the float 320, the float 320 can provide the maximum force to the sealing component 200 through the connecting rod 310, so that the sealing component 200 stably blocks the water inlet channel 110, thereby improving the reliability of the tank assembly.

[0038] See Figure 1 and Figure 2In one embodiment, the connecting rod 310 further includes a third rod segment 313, and the second rod segment 312 is connected to the first rod segment 311 through the third rod segment 313. The second rod segment 312 is parallel to the first rod segment 311, so that when the central axis of the float 320 is parallel to the horizontal plane, that is, when the float 320 is subjected to the maximum buoyancy, the second rod segment 312 will not be subjected to a force that moves away from the float 320, so that the second rod segment 312 is stably connected to the float 320.

[0039] Furthermore, the connecting rod 310 is provided with reinforcing ribs 314 to increase the strength of the connecting rod 310. Reinforcing ribs 314 are provided on both sides of the connecting rod 310 in the horizontal direction, and are located at the upper and lower ends of the connecting rod 310, extending along the extension direction of the connecting rod 310.

[0040] See Figure 2 and Figure 3 , Figure 3 This is a cross-sectional schematic diagram of the water inlet connector in a water tank assembly provided in one embodiment of this application. In one embodiment, the water tank assembly further includes a partition 130, which is connected to the inner wall of the water inlet channel 110 and divides the water inlet channel 110 into a first hole segment 111 and a second hole segment 112. The second hole segment 112 is located below the first hole segment 111, and a sealing member 200 is disposed in the second hole segment 112. The partition 130 has a through hole 133, and the sealing member 200 blocks the through hole 133 when it is in the first position.

[0041] Specifically, when the sealing member 200 is in the first position, it abuts against the partition 130 to block the through hole 133, thereby blocking the connection between the first hole segment 111 and the second hole segment 112, i.e., blocking the water inlet channel 110. When the water level drops and the sealing member 200 moves away from the partition 130 to the second position, it releases the through hole 133, allowing the first hole segment 111 and the second hole segment 112 to connect, thus enabling the water tank body to be replenished with water through the water inlet channel 110.

[0042] See Figure 2 and Figure 3 In one embodiment, the partition 130 includes an annular plate 131 and a boss 132. The outer side of the annular plate 131 is connected to the inner wall of the water inlet channel 110, and the boss 132 is connected to the inner side of the annular plate 131 and protrudes toward the sealing member 200. A through hole 133 is provided on the boss 132, and the outer contour area of ​​the boss 132 gradually decreases in the direction from the first hole segment 111 to the second hole segment 112.

[0043] Specifically, the sealing member 200 includes a piston 230. As the sealing member 200 moves closer to the through hole 133 to the first position, the contact force between the piston 230 and the boss 132 increases. Because the outer contour area of ​​the boss 132 gradually decreases in the direction from the first hole segment 111 to the second hole segment 112, the piston 230 can deform and fit against the outer contour of the boss 132, thereby improving the sealing performance of the through hole 133 and the sealing effect of the water inlet channel 110. Preferably, the outer contour of the boss 132 is arc-shaped.

[0044] See Figure 2 and Figure 3 In one embodiment, the sealing member 200 is slidably connected to the inner wall of the second hole segment 112, and the sealing member 200 has a water flow channel for communicating with the water inlet channel 110 when the sealing member 200 is in the second position.

[0045] Specifically, the sealing component 200 is slidably connected to the inner wall of the second hole section 112, thereby playing a guiding role. As the connecting rod 310 moves with the float 320, the sealing component 200 can move stably along the extension direction of the second hole section 112 to accurately seal the through hole 133 and ensure the sealing effect of the water inlet channel 110.

[0046] Furthermore, the sealing component 200 also includes a sealing block 220 and multiple protrusions. The sealing block 220 has a mounting groove 221 for accommodating the piston 230, and the sealing block 220 abuts against the connecting rod 310. The multiple protrusions are connected to the outer wall of the sealing block 220 and abut against the inner wall of the second hole section 112. The protrusions are spaced apart to form a water flow channel, so that when the sealing component 200 is in the second position, the water tank body can enter water through the water inlet channel 110. Preferably, the protrusions are evenly arranged around the circumference of the sealing block 220.

[0047] The sealing block 220 is also provided with a groove that communicates with the mounting groove 221, so as to make the sealing component 200 lightweight.

[0048] See Figure 1 and Figure 2 In one embodiment, the top wall of the water tank body is provided with a water inlet connector 120, which defines a water inlet channel 110, and the end of the connecting rod 310 away from the float 320 is rotatably connected to the water inlet connector 120.

[0049] Specifically, the end of the first rod segment 311 away from the second rod segment 312 is rotatably connected to the water inlet connector 120. The transmission position of the connecting rod 310 and the sealing block 220 is located on the side near the float 320 at the rotatable connection between the first rod segment 311 and the water inlet connector 120, thereby forming a lever structure, increasing the driving force at the transmission position of the connecting rod 310 and the sealing block 220, so as to improve the driving force of the driving piston 230 to block the through hole 133 and ensure the sealing effect of the water inlet channel 110.

[0050] See Figure 1 and Figure 2 In one embodiment, at least a portion of the connecting rod 310 is located below the water inlet channel 110 and abuts against the sealing member 200. Thus, when the float 320 moves upward with the water level, causing the connecting rod 310 to move, the connecting rod 310 can exert an upward thrust on the sealing member 200, causing the sealing member 200 to move towards a first position to block the water inlet channel 110. Conversely, when the water level drops and the float 320 moves downward, the sealing member 200 moves from the first position to a second position by its own weight or the force of water pressure.

[0051] See Figure 1 , Figure 2 and Figure 3 In one embodiment, the water inlet connector 120 is provided with a stop portion 121, which is used to abut against the connecting rod 310 to restrict the end of the connecting rod 310 near the float 320 from moving away from the water inlet channel 110, so as to restrict the sealing member 200 from coming out through the outlet end of the water inlet channel 110.

[0052] Specifically, the stop part 121 is used to abut against the end of the connecting rod 310 away from the float 320. When the water level drops and the float 320 moves down, the stop part 121 can stop the stroke of the float 320's rotation, preventing the float 320 from rotating too much and causing the float 320 to float upward in the opposite direction, and also preventing the sealing part 200 from falling out of the water inlet channel 110 due to the excessive rotation angle of the float 320.

[0053] Furthermore, the stop 121 is used to abut against the upper end of the connecting rod 310, thereby preventing interference with the connecting rod 310 extending into the water inlet connector 120 and rotating through the water inlet connector 120.

[0054] See Figure 2 and Figure 3 In one embodiment, the blocking block 220 has an abutment surface 210 on the side opposite to the piston 230. The abutment surface 210 is arc-shaped and is used to abut against the connecting rod 310. As the connecting rod 310 moves with the float 320, the connecting rod 310 can always maintain line contact with the abutment surface 210, thereby stably applying driving force to the blocking member 200.

[0055] See Figures 1-3 This application also provides a drinking water device, including the aforementioned water tank assembly. In this application, a float 320 is installed inside the water storage chamber. As the float 320 moves with the water level, it drives a connecting rod 310 to move. When the water level reaches a predetermined level, the connecting rod 310 can drive the sealing member 200 to move to a first position to stop further water intake into the water storage chamber. Because the height of the float 320 is lower than the height of the sealing member 200, the float 320 is completely submerged in water when the water tank is not full. This provides maximum buoyancy to the connecting rod 310, enabling it to transmit power to the sealing member 200 to block the water inlet channel 110, thereby improving the sealing performance.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
