[0002] Conventional water dispensers are top-mounted, meaning the bottled water is placed upside down on top. Changing the bottled water often requires lifting and flipping the dispenser, making it very laborious. Consequently, bottom-mounted water dispensers have gradually emerged on the market. These dispensers feature a base for discharging water, allowing bottled water to be placed underneath.

[0003] However, when a heavy object (bottled water) is pushed into the existing bottom-mounted water dispenser, the bottom surface of the bottled water and the base are in surface contact, resulting in large friction, making it difficult to push the object in, and resulting in a poor user experience.

[0033] like Figures 1-4 As shown, the present invention provides a base, which includes a base body 100 and a support plate 200. The base body 100 is provided with a plurality of first rolling elements 110. The support plate 200 is disposed on the base body 100 and is movable between a first position and a second position. The support plate 200 is provided with a loading surface and a plurality of through holes 201 located on the loading surface. The plurality of through holes 201 and the plurality of first rolling elements 110 are provided in a corresponding manner.

[0034] When the support plate 200 is in the first position, the first rolling element 110 is hidden between the loading surface and the base body 100. When the support plate 200 is in the second position, the first rolling element 110 at least partially passes through the through hole 201 and protrudes from the side of the loading surface away from the base body 100.

[0035] It should be noted that the plurality of through holes 201 and the plurality of first rolling elements 110 are correspondingly arranged, that is, generally, each through hole 201 is aligned with a first rolling element 110 so that as the support plate 200 moves, the first rolling element 110 can protrude from the loading surface.

[0036] Generally, when the support plate 200 is in the first position, it is located on the side of the first rolling element 110 facing away from the base body 100. This means that when the support plate 200 is in the first position, the first rolling element 110 is located below the support plate 200. When no heavy object (bottled water) is placed on the support plate 200, the support plate 200 is generally in the first position. However, placing a heavy object on the support plate 200 can move the support plate 200 from the first position to the second position, causing the first rolling element 110 to protrude from the load surface of the support plate 200, thereby supporting the heavy object (bottled water). This converts the original surface-to-surface contact between the heavy object (bottled water) and the support plate 200 into rolling contact, which is more conducive to the movement of the heavy object (bottled water) on the support plate 200.

[0037] That is, it can be understood that the present invention converts the original surface contact between the heavy object (bottled water) and the support plate 200 into rolling contact, and at the same time utilizes the rolling characteristics of the first rolling element 110 to enable the heavy object (bottled water) to easily slide into the center of the base, which saves more effort when replacing bottled water in the water dispenser and improves the efficiency of replacing bottled water in the water dispenser.

[0038] Typically, the first rolling element 110 is a ball bearing. Multiple first rolling elements 110 are typically arranged in an array on the base body 100 to ensure that the first rolling elements 110, after protruding from the load surface of the support plate 200, can support the heavy object (bottled water) at all locations and ensure the balance of the heavy object (bottled water). The first rolling elements 110 are typically fixedly mounted on the base body 100 and can rotate in place under the action of external forces.

[0039] When the support plate 200 is in the second position, the first rolling element 110 can partially pass through the through hole 201 and protrude from the side of the loading surface away from the base body 100, that is, the first rolling element 110 partially protrudes from the loading surface. Alternatively, the first rolling element 110 can completely pass through the through hole 201 and protrude from the loading surface.

[0040] In some embodiments, the base also includes a first elastic member 210, one end of the first elastic member 210 is connected to the base body 100, and the other end of the first elastic member 210 is connected to the support plate 200, and the first elastic member 210 is used to hover at the first position when the support plate 200 is not subjected to pressure, and to drive the support plate 200 to move toward the first position when the pressure on the support plate 200 is reduced.

[0041] It is understandable that by providing the first elastic member 210 and utilizing the elastic deformation of the first elastic member 210 , the floating position change of the support plate 200 after the pressure is applied and the pressure is released is achieved.

[0042] That is, when the pressure on the support plate 200 increases, the support plate 200 will move from the first position to the second position, causing the first rolling member 110 originally located below the support plate 200 to gradually pass through the support plate 200 and come above the support plate 200, so as to contact the heavy object (bottled water) on the support plate 200. This converts the surface friction between the heavy object (bottled water) and the support plate 200 into rolling friction between the heavy object (bottled water) and the first rolling member 110, thereby reducing the friction between the heavy object (bottled water) and the base, making it easier to move to the center of the base. In other words, the present invention converts the original surface contact between the heavy object (bottled water) and the support plate 200 into rolling contact. At the same time, by utilizing the rolling characteristics of the first rolling member 110, the heavy object (bottled water) can easily slide into the center of the base, saving effort when replacing bottled water in the water dispenser and improving the efficiency of replacing bottled water in the water dispenser.

[0043] On the other hand, as the amount of water in the heavy object (bottled water) gradually decreases, the weight of the heavy object (bottled water) gradually decreases, and the pressure applied to the support plate 200 gradually decreases, so that the support plate 200 begins to move toward the first position, causing the first rolling element 110 to gradually retract to the bottom of the support plate 200, and the heavy object (bottled water) and the support plate 200 resume surface-to-surface contact, avoiding the situation where the heavy object (bottled water) is easily shaken due to the weight reduction.

[0044] Generally, the first elastic member 210 is a spring, and a plurality of springs are provided on the base. The plurality of springs are distributed in an array on the base body 100 and are connected to the support plate 200 so that all parts of the support plate 200 can be subjected to elastic action. On the one hand, the loading surface of the support plate 200 can be kept horizontal when in the first position. On the other hand, when the weight of the heavy object is gradually reduced to a certain extent, there can be sufficient elasticity to move the support plate 200 toward the first position.

[0045] Generally, when no weight is placed on the support plate 200 , the first elastic member 210 is in a compressed state, and at this time, the top of the first elastic member 210 is flush with the top of the first rolling member 110 .

[0046] In other embodiments, an electric lifting device is provided between the support plate 200 and the base, and is used to drive the support plate 200 to move between the first position and the second position. A weight sensor is also provided on the electric lifting device, and is used to detect the weight of the support plate 200. When a heavy object (e.g., bottled water) is placed on the support plate 200, the weight sensor detects that the weight of the support plate 200 exceeds a preset value, and then controls the electric lifting device to drive the support plate 200 from the first position to the second position, causing the first rolling element 110 to gradually pass through the support plate 200. When the weight sensor detects that the weight of the support plate 200 is less than the preset value, the electric lifting device is controlled to drive the support plate 200 to move toward the first position.

[0047] In some embodiments, the base also includes a first connecting rod 221 and a second connecting rod 222, one end of the first connecting rod 221 is rotatably connected to the base body 100, the other end of the first connecting rod 221 is connected to the support plate 200, one end of the second connecting rod 222 is rotatably connected to the base body 100, and the other end of the second connecting rod 222 is connected to the support plate 200, the connection between the first connecting rod 221 and the support plate 200 and the connection between the second connecting rod and the support plate 200 are respectively located at both ends of the support plate 200, the first connecting rod 221 and the second connecting rod 222 are connected to each other and are configured as follows: when the support plate 200 moves toward the second position, the first connecting rod 221 rotates accordingly and drives the second connecting rod 222 to rotate, and when the support plate 200 moves toward the first position, the second connecting rod 222 rotates accordingly and drives the first connecting rod 221 to rotate.

[0048] It is understood that the first connecting rod 221 and the second connecting rod 222 are both rotatably connected to the base body 100 and are also connected to the support plate 200. Therefore, as the support plate 200 moves between the first position and the second position, the first connecting rod 221 and the second connecting rod 222 can also rotate accordingly, and the movement direction of the support plate 200 is consistent with that of the first connecting rod 221 and the second connecting rod 222. Through configuration, the first connecting rod 221 can drive the second connecting rod 222 to rotate when the support plate 200 moves toward the second position. At the same time, because the first connecting rod 221 and the second connecting rod 222 are respectively connected to the ends of the support plate 200, the synchronous movement of the first connecting rod 221 and the second connecting rod 222 can keep the loading surface of the support plate 200 level during movement.

[0049] Likewise, the second connecting rod 222 can drive the first connecting rod 221 to rotate when the support plate 200 moves toward the first position, and can also ensure that the loading surface of the support plate 200 remains horizontal during the movement.

[0050] Specifically, the first connecting rod 221 and the second connecting rod 222 are arranged crosswise and connected, so that the connection points of the first connecting rod 221 and the second connecting rod 222 with the support plate 200 are respectively located at the two ends of the support plate 200, so that the rotation of the first connecting rod 221 and the second connecting rod 222 can maintain the loading surface of the support plate 200 horizontal. The first connecting rod 221 has a pressing portion on one side, and the second connecting rod 222 has a groove on one side. The pressing portion and the groove are connected, so that when the support plate 200 moves toward the second position, the first connecting rod 221 rotates accordingly and drives the second connecting rod 222 to rotate. When the support plate 200 moves toward the first position, the second connecting rod 222 rotates accordingly and drives the first connecting rod 221 to rotate.

[0051] In some embodiments, the base includes a front shovel member 400, which is arranged on one side of the base body 100 and connected to the base body 100. The front shovel member 400 has a slope portion 401, and the top of the slope portion 401 is flush with the loading surface of the support plate 200 in the first position.

[0052] It is understandable that the slope portion 401 of the front shovel 400 is used to allow heavy objects (bottled water) to slide or roll along the slope portion 401 from the ground to the support plate 200, which can avoid the situation of directly carrying the bottled water and placing it, saving manpower.

[0053] Furthermore, in some embodiments, a plurality of second rolling elements 410 are further provided on the front shovel member 400 , and the plurality of second rolling elements 410 all protrude from the broken surface of the slope portion 401 .

[0054] It can be understood that multiple second rolling members 410 are provided on the front shovel member 400 and protrude from the slope portion 401, which can play an auxiliary role when the heavy object (bottled water) moves from the slope portion 401 to the support plate 200, reduce friction work, and thus save manpower.

[0055] Generally, the second rolling element 410 is also a ball.

[0056] In some embodiments, the base further includes a clamping device, which is provided on the base body 100 and is used to clamp the heavy object on the support plate 200. That is, the heavy object (barreled water) is fixed by the clamping device to prevent it from shaking on the support plate 200.

[0057] In some embodiments, the clamping device includes two oppositely arranged first clamping arms 300, the first clamping arms 300 are rotatably connected to the base body 100, and the first clamping arms 300 are configured to rotate between a third position and a fourth position. When the first clamping arm 300 is in the third position, the clamping device is in an open state, and when the first clamping arm 300 is in the fourth position, the clamping device is in a clamping state.

[0058] Generally, the two first clamping arms 300 are disposed on both sides of the support plate 200 , so that the two first clamping arms 300 can clamp the heavy objects on the support plate 200 .

[0059] Specifically, a connecting shaft 330 is provided at the bottom of the first clamping arm 300 , and a connecting hole is provided on the base body 100 . The connecting shaft 330 is rotatably connected to the connecting hole to realize the rotatable connection between the first clamping arm 300 and the base body 100 .

[0060] In some embodiments, a third rolling member 310 is provided on the first clamping arm 300, and a first groove and a second groove spaced apart from each other are provided on the base body 100. The third rolling member 310 can move between the first groove and the second groove as the first clamping arm 300 moves between the third position and the fourth position. When the first clamping arm 300 is in the third position, the third rolling member 310 is in the first groove. When the first clamping arm 300 is in the fourth position, the third rolling member 310 is in the second groove.

[0061] The third rolling element 310 is configured to retract into the first clamping arm 300 when moving between the first groove and the second groove, and protrude from the bottom of the first clamping arm 300 when in the first groove and the second groove and cooperate with the first groove and the second groove.

[0062] Specifically, the first clamping arm 300 has a blind hole arranged in the vertical direction, and a third elastic member 301 is arranged in the blind hole. A fixing plate 320 connected to the first clamping arm 300 is arranged on the outside of the blind hole. The fixing plate 320 is used to fix the third rolling member 310 between the third elastic member 301 and the fixing plate 320, and when the third rolling member 310 is pressurized, the third elastic member 301 can be compressed and retracted into the blind hole, so that the first clamping arm 300 can rotate relative to the base body. At the same time, a reducing hole is provided on the fixing plate 320, which is used to allow the third rolling member 310 to partially protrude from the fixing plate 320 under the action of the third elastic member 301 when it is not compressed, so as to better cooperate with the first groove and the second groove.

[0063] Specifically, the fixing piece 320 is fixed to the first clamping arm 300 by screws.

[0064] It can be understood that by rotating the first clamping arm 300, the third rolling element 310 is forced to be compressed and thus retracted into the first clamping arm 300, so that the first clamping arm 300 can be rotated between the third position and the fourth position; and after rotating to the third position or the fourth position, due to the structural characteristics of the groove, it is relatively lower than the plane of the base body 100, so that the third rolling element 310 is not compressed, thereby protruding from the bottom of the first clamping arm 300 and forming a concave-convex fit with the first groove and the second groove. Through the concave-convex fit of the first groove and the third rolling element 310, the first clamping arm 300 can be fixed in the third position and not easily shaken. Through the concave-convex fit of the second groove and the third rolling element 310, the first clamping arm 300 is not easily shaken, thereby restricting the movement of the first clamping arm 300 to ensure the clamping force for heavy objects (bottled water).

[0065] In other embodiments, a protruding third rolling member 310 is provided on the base body. The third rolling member 310 is configured to remain protruding when the first clamping arm 300 is in the third and fourth positions, thereby limiting the position of the first clamping arm 300. The third rolling member 310 is further configured to retract into the base body 100 when the first clamping arm 300 passes the third rolling member 310, allowing the third rolling member 310 to rotate between the third and fourth positions. After the first clamping arm 300 passes the third rolling member 310, the third rolling member 310 protrudes from the surface of the base body 100.

[0066] It should be noted that when the third rolling element 310 is in the protruding state, it is generally in an incompletely protruding state.

[0067] Specifically, the base body is provided with a fixed structure, and a third elastic member 301 is disposed between the fixed structure and the third rolling member 310. Furthermore, the base body is provided with a vertical channel, and the third rolling member 310 is disposed in the channel so that the third rolling member 310 can be pressed and moved in the vertical direction. When the first clamping arm 300 rotates onto the third rolling member 310, the first clamping arm 300 applies a vertical force to the third rolling member 310, causing the third rolling member 310 to retract into the base body. The first clamping arm 300 can rotate past the third rolling member 310. After the first clamping arm 300 rotates past the third rolling member 310, the pressure on the third rolling member 310 disappears, and the third elastic member 301 then drives the third rolling member 310 into a protruding state, thereby limiting the position of the first clamping arm 300.

[0068] In some embodiments, the present invention further provides a water dispenser, comprising a water dispenser body and the above-mentioned base, wherein the water dispenser body is provided with a receiving cavity, and the base is provided in the receiving cavity.

[0069] Since the water dispenser includes the base of the above embodiment or the combined embodiment, it has at least some or all of the beneficial effects of the above base, which will not be described in detail here.

[0070] In some embodiments, the base is slidably connected to the water dispenser body so that the base can slide out of and into the accommodating cavity.

[0071] Generally, two sides of the base are slidably connected to two sides of the water dispenser body respectively, so that the base is slidably connected to the water dispenser body.

[0072] That is, when the bottled water needs to be replaced, the base is slid out of the accommodating cavity, and after the bottled water is replaced, the base is slid into the accommodating cavity.

[0073] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the application concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
