[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figure 1As shown, the water-pumping filter structure provided in the embodiment of this utility model includes a water tank 100, a filter assembly 200, and a water pump 300. The water tank 100 has a water storage chamber 110 inside, and a drain outlet 120 at the bottom of the water tank 100, which communicates with the water storage chamber 110. The filter assembly 200 includes a barrel 210 and filter media 220. The barrel 210 is installed on the bottom inside the water storage chamber 110, as shown. Figure 1 , 2 As shown, the barrel 210 has a receiving cavity 211 inside, the filter media 220 is located in the receiving cavity 211, the barrel 210 has an inlet 212 and an outlet 213 communicating with the receiving cavity 211, the filter media 220 has an inlet surface 221 and an outlet surface 222, the inlet surface 221 is communicating with the inlet 212, and the outlet 213 is communicating with the outlet surface 222 and the drain outlet 120 respectively; the water pump 300 is located outside the water tank 100, and the inlet of the water pump 300 is communicating with the drain outlet 120.

[0032] By installing a filter assembly 200 inside the water tank 100, when the water pump 300 is started, the water in the water tank 100 is filtered by the filter material 220 and then discharged from the drain outlet 120 of the water tank 100, so that the water tank 100 can not only store water, but also perform preliminary filtration of water.

[0033] When in operation, the water pump 300 starts. Under negative pressure, the water in the water tank 100 enters the tank body 210 through the inlet 212, and then enters the filter media 220 through the inlet surface 221. The filter media 220 filters the water that has passed through it. The filtered water is discharged from the outlet surface 222, and then discharged from the water tank 100 through the outlet 213 and the drain outlet 120. The water pump 300 delivers the filtered water to other structures of the water dispenser.

[0034] Specifically, the filter media 220 can be a PP cotton filter element, a carbon rod filter element, or other filter elements with one inlet and one outlet.

[0035] Furthermore, such as Figure 2 As shown, the inlet 212 is located on the outer wall of the barrel 210, and the outlet 213 is located at the bottom of the barrel 210.

[0036] The inlet 212 and outlet 213 are configured in the above manner, which facilitates water entering the tank 210 and water exiting from the drain 120 without the need for additional piping.

[0037] Furthermore, the filter media 220 is annular, with the outer wall of the filter media 220 serving as the inlet surface 221 and the inner wall of the filter media 220 serving as the outlet surface 222. A flow cavity 400 is formed between the outer wall of the filter media 220 and the inner wall of the receiving cavity 211.

[0038] The filter media 220 adopts the above-mentioned configuration and is provided with a flow cavity 400, which facilitates water to fill the outer wall of the filter media 220 and makes full use of the filter media 220.

[0039] Furthermore, such as Figure 2 As shown, the barrel 210 includes a barrel body 214 and a barrel lid 215. The barrel lid 215 is detachably installed on the top inside the barrel body 214. The barrel body 214 and the barrel lid 215 enclose a receiving cavity 211. The water inlet 212 is located on the outer wall of the barrel body 214, and the water outlet 213 is located on the lower end face of the barrel body 214.

[0040] The barrel 210 adopts the above-mentioned configuration, which facilitates the replacement of filter media 220.

[0041] Furthermore, such as Figure 2 As shown, the bottom of the lid 215 and the bottom of the inside of the body 214 both have a first annular rib 2151 and a second annular rib 2152. The second annular rib 2152 is located inside the first annular rib 2151, and the filter material 220 is placed between the first annular rib 2151 and the second annular rib 2152.

[0042] By setting the first annular rib 2151 and the second annular rib 2152, the filter material 220 is fixed to prevent the filter material 220 from moving under negative pressure and affecting the filtration effect.

[0043] It is understandable that the upper end face of the first annular rib 2151 on the barrel body 214 is lower than the upper end face of the water inlet 212, so as to ensure that the first annular rib 2151 on the barrel body 214 will not affect the water entering the barrel body 210 from the water inlet 212.

[0044] Furthermore, such as Figure 2 As shown, a sealing ring 500 is provided between the outer wall of the first annular rib 2151 of the lid 215 and the barrel body 214 to ensure the sealing effect inside the barrel body 210.

[0045] Furthermore, the barrel 210 is detachably mounted on the water tank 100, allowing the user to choose whether to install the filter assembly 200 or to facilitate the maintenance of the filter assembly 200.

[0046] Furthermore, such as Figure 1 , 3 As shown in Figure 4, the bottom surface 111 inside the water storage chamber 110 has a sink trough 130, the drain outlet 120 is located on the sink trough 130, and the barrel 210 is detachably installed in the sink trough 130. The bottom surface 111 is higher than the bottom wall 2121 of the water inlet 212.

[0047] By providing a sink trough 130 and having a bottom surface 111 higher than the bottom wall 2121 of the inlet 212, the filter assembly 200 can drain the water in the water storage chamber 110.

[0048] Furthermore, such as Figure 3 , 5 As shown, the interior of the sink trough 130 has a plurality of first locking portions 131 spaced apart along the circumferential direction, and the outer wall of the barrel body 214 has a plurality of second locking portions 2141 spaced apart along the circumferential direction. The positions of the plurality of first locking portions 131 correspond one-to-one with the positions of the plurality of second locking portions 2141, and the first locking portions 131 and the second locking portions 2141 are rotatably locked together.

[0049] The barrel 214 is rotated and snapped into the first snap-fit ​​part 131 of the water tank 100 via the second snap-fit ​​part 2141, so that the user can install and remove the filter assembly 200 without additional tools.

[0050] Specifically, one side of the first snap-fit ​​part 131 has a groove. Before assembly, the second snap-fit ​​part 2141 of the barrel body 214 is positioned on one side of the first snap-fit ​​part 131. Then, the barrel body 214 is rotated so that the second snap-fit ​​part 2141 is rotated into the groove of the first snap-fit ​​part 131, thereby achieving a rotatable snap-fit ​​between the first snap-fit ​​part 131 and the second snap-fit ​​part 2141.

[0051] Furthermore, such as Figure 7 As shown, there are multiple water inlets 212. The multiple water inlets 212 are divided into left and right parts along the left and right directions. The multiple water inlets 212 on the left and the multiple water inlets 212 on the right are arranged at intervals along the front and back directions. The multiple water inlets 212 on the left correspond one-to-one with the multiple water inlets 212 on the right. Each water inlet 212 extends along the left and right directions.

[0052] Each inlet 212 extends in the left-right direction, and the inlet 212 on the left and the inlet 212 on the right are on the same straight line, which facilitates demolding and reduces the difficulty of mold processing.

[0053] like Figure 7 As shown, each inlet 212 extends in the left and right direction, meaning that the front sidewall 2121 and the rear sidewall 2122 of the inlet 212 are parallel to each other and both extend in the left and right direction.

[0054] Although the technical solutions of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these technical solutions without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents.
