This patent solution aims to address the problem of bacterial growth caused by residual moisture in the water pipe of existing water dispensers. Utility Model Content

[0035] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0036] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0037] Example 1

[0038] like Figure 1-5 A noise-reducing drainage pump includes a housing, a pump body 103 suitable for pressurizing and conveying a fluid, a water conduit, a solenoid valve 119, a water inlet pipe 104, and a water outlet pipe 105. The housing includes a first housing 101 and a second housing 102 that are mated together. A cavity is formed within the housing to accommodate the pump body 103, the water outlet pipe 104, a portion of the water conduit, and the solenoid valve 119. The water conduit and the solenoid valve 119 are arranged on the same side of the pump body 103. The pump body 103, the water conduit, and the solenoid valve 119 are housed in the housing and assembled into an integrated structure. The water inlet pipe 104 is suitable for introducing water into the pump body 103. The water inlet pipe 104 is exposed outside the housing. The water inlet pipe 104 and the water outlet pipe 105 are suitable for being arranged side by side front and back along the thickness direction of the pump body 103. The water outlet pipe includes a vertical section 117 and a horizontal section 118. The vertical section 117 is connected to the pump body 103. The water conduit includes a vertically arranged main passage, a first branch 108 located on one side of the main passage close to the pump body 103, a second branch 109 located on the other side of the main passage, and a third branch 110. The first branch 108 is adapted to connect the water outlet pipe 105 and the horizontal section 118, and the third branch 110 is adapted to connect the main passage and the drain port 124. The solenoid valve 119 includes a valve body 120, a piston 121, and a plug 122 disposed at the end of the piston 121. The valve body 120 includes an electromagnetic coil adapted to provide magnetic force. The piston 121 is adapted to drive the plug 122 to slide back and forth within the main passage under the drive of the magnetic force.

[0039] In this embodiment, the second branch 109 and the third branch 110 are adapted to extend out of the housing. The first branch 108 and the second branch 109 are arranged symmetrically. The third branch 110 is located above the second branch 109. The solenoid valve 119 is located above the water pipe. This design is compact and has a neat and compact structure. The main passage includes a regulating section 111 located between the first branch 108 and the third branch 110. The regulating section 111 includes a first port 112 and a second port 113. The main passage is equipped with an arcuate peripheral wall 114, which is suitable for separating the main passage into a first secondary passage 115 suitable for connecting to the first branch 108 and a second secondary passage 116 suitable for connecting to the second branch 109. The first secondary passage includes a first open end suitable for forming a first port 112. The plug 122 is suitable for sealing the first port 112 to cut off the connection between the first branch 108 and the main passage. At this time, the drainage passage is connected. The plug 122 is suitable for sealing the second port 113 to cut off the connection between the third branch 110 and the main passage. At this time, the water outlet passage is connected.

[0040] When the pump body 103 is operating, the solenoid valve 119 is closed, the plug 122 is adapted to block the third branch 110, and the outlet pipe 105, the first branch 108, and the second branch 109 form a water outlet passage, which is connected. When the pump body 103 is shut down, the solenoid valve 119 is energized and the plug 122 is adapted to block the first branch 108. The second branch 109, the main passage, and the third branch 110 form a drainage passage, and the water outlet passage is closed. After the drainage passage is connected, it is closed again 1-5 seconds later, and the water outlet passage is restored to connection.

[0041] In this embodiment, the water conduit includes a first water conduit 106 and a second water conduit 107 coaxially extended to form a main channel. The first water conduit 106 includes a first branch 108 and a second branch 109, and the second water conduit 107 includes a third branch 110. The first water conduit 106, the second water conduit 107, and the valve body 120 are sequentially connected and assembled into a single unit via a plurality of circumferentially evenly distributed or arrayed bolt structures 123. This design helps improve the integrity of the water conduit and the solenoid valve 119, reduces eccentricity during the movement of the plug 122, and facilitates maintenance of the water conduit, avoiding the difficulty of maintenance caused by an excessively long main channel.

[0042] Example 2

[0043] A noise-reducing drainage water pump, compared with Example 1, differs in that the third branch 110 is located below the first branch 108 and the second branch 109. When the drainage passage is opened and there is no external force, the water outlet passage remains unobstructed, and the water in the second branch 109 flows into the third branch 110 through the main passage under the action of gravity. The water in the vertical section 117 is suitable for flowing back to the horizontal section 118 under the action of gravity, and the water in the horizontal section 118 then flows into the third branch 110 through the main passage. This design makes it suitable for the residual water in the water outlet passage to be further and thoroughly discharged through the drainage passage under the action of gravity, thereby further improving the emptying efficiency.

[0044] Example 3

[0045] like Figure 4-5 A water dispenser includes a water heating device, a water receiving device and the noise reduction drainage water pump of Example 1. The water heating device includes a water storage container 201 suitable for storing drinking water, a base 202 suitable for supporting the water storage container 201 and a heating device suitable for heating drinking water. The water receiving device includes a storage table 203 and a water outlet 204 arranged above the storage table 203. The storage table 203 has a detachable waste water box 205 built in. The noise reduction drainage water pump is arranged inside the base 202. The water pump is suitable for pumping drinking water to the water outlet 204. The water outlet passage is connected to the water outlet through the first pipe body, and the third branch 110 directly extends into the waste water box 205.
