Of course, those skilled in the art will understand that the above structure is only a specific example and schematic description and does not constitute a specific limitation of the technical solution provided in this application.

[0054] Reference Figures 1 to 12 As shown, the present application provides a desktop water purifier, including a filter unit, a pure water kettle 1, an instant heating body 2, an insulation device 3 and a water outlet 4. The filter unit is connected to the kettle body inlet of the pure water kettle 1, and the water outlet of the instant heating body 2 is connected to either the water outlet 4 or the insulation water inlet of the insulation device 3. The desktop water purifier also includes an integrated waterway plate 5, and the integrated waterway plate 5 includes a plate body 51. The plate body 51 is provided with a cold water channel 511, a hot water channel 512 and a drain outlet 513. The cold water channel 511 is used to connect the kettle body outlet of the pure water kettle 1 and the drain outlet 513, and the hot water channel 512 is used to connect the insulation water outlet of the insulation device 3 and the drain outlet 513. The drain outlet 513 is connected to the water inlet of the instant heating body 2.

[0055] In the desktop water purifier provided in the present application, the filter unit is connected with the pot body inlet of the pure water kettle 1, and the pure water filtered by the filter unit can be transported to the pure water kettle 1 for storage, and the water outlet of the heating body 2 is connected with the water outlet nozzle 4 and the heat preservation water inlet of the heat preservation device 3, so that the hot water heated by the heating body 2 can be directly transported to the water outlet nozzle 4 for discharge, or transported to the heat preservation device 3 for heat preservation storage, which can be specifically achieved through the water diversion valve 100; the plate body 51 of the integrated waterway plate 5 is provided with a cold water channel 511, a hot water channel 512 and a drain port 513, the cold water channel 511 is used to connect the pot body outlet and the drain port 513 of the pure water kettle 1, the hot water channel 512 is used to connect the heat preservation water outlet and the drain port 513 of the heat preservation device 3, and the drain port 513 is connected with the water inlet of the heating body 2. The water is transported to the instant heating body 2 through the cold water channel 511 and the drain outlet 513 for heating, and the warm water stored in the insulation device 3 can be transported to the instant heating body 2 through the hot water channel 512 and the drain outlet 513 for secondary heating. The normal temperature pure water and the warm water can also be transported to the instant heating body 2 for heating at the same time, so that the instant heating body 2 can instantly heat water of different temperatures, and then after heating per unit time, water of different temperatures is transported to the water outlet 4, so as to meet the user's various water needs and enhance the user experience. In addition, the flow path of the normal temperature pure water transported by the pure water kettle 1 to the instant heating body 2 and the flow path of the warm water transported by the insulation device 3 to the instant heating body 2 are both integrated on the plate body 51, realizing the multifunctional integration of the integrated waterway plate 5, which helps to reduce the number of water pipe accessories used, simplify the waterway structure, improve the simplicity of the waterway structure layout, and reduce the risk of water leakage.

[0056] When the desktop water purifier is working, the filtration unit (not shown in the attached drawings, it can use a reverse osmosis filter element, a composite filter element with a reverse osmosis filter element, etc.) filters the municipal tap water and other raw water into pure water, and then the pure water can be transported to the pure water kettle 1 for storage. When the instant heating body 2 needs to be heated, the pure water kettle 1 transports the pure water to the instant heating body 2 for heating. The heated pure water can be transported to the water outlet 4 or the insulation device 3 for insulation storage. When the instant heating body 2 takes water for heating again, you can choose the pure water kettle 1 or the insulation device 3 to supply water to the instant heating body 2 alone, or the pure water kettle 1 and the insulation device 3 can supply water to the instant heating body 2 together.

[0057] As a preferred embodiment of the present application, Figures 3 to 6 As shown, the integrated waterway plate 5 also includes a cold water pump 52 and a hot water pump 53 respectively mounted on the plate body 51. The cold water pump 52 is arranged on the fluid path of the cold water channel 511, and the hot water pump 53 is arranged on the fluid path of the hot water channel 512. Those skilled in the art will understand that the cold water pump 52 and the hot water pump 53 are mounted on the plate body 51. The cold water pump 52 acts on the cold water channel 511 to pump water from the pure water kettle 1 to the instant heating element 2. The hot water pump 53 acts on the hot water channel 512 to pump water from the heat preservation device 3 to the instant heating element 2. Therefore, the cold water pump 52 and the hot water pump 53 can be controlled by a program to selectively operate or operate simultaneously, thereby realizing switching between three modes: the pure water kettle 1 supplies water to the instant heating element 2 alone, the heat preservation device 3 supplies water to the instant heating element 2 alone, and the pure water kettle 1 and the heat preservation device 3 supply water to the instant heating element 2 together. The operation is convenient and simple, and the degree of automatic intelligence is high.

[0058] In a preferred embodiment, if Figure 6 As shown, the plate body 51 is provided with a water mixing channel 514, and the cold water channel 511, the hot water channel 512, and the drain port 513 are respectively connected to the water mixing channel 514. The water mixing channel 514 serves as a transfer channel connecting the cold water channel 511 and the hot water channel 512 with the drain port 513. The mixing channel 514 is shared by both room temperature pure water and warm water, which improves the channel integration and simplifies the structure of the plate body 51. When the pure water kettle 1 supplies water to the instant heating body 2 alone, the room temperature pure water flows to the drain outlet 513 through the mixing water channel 514; when the heat preservation device 3 supplies water to the instant heating body 2 alone, the warm water flows to the drain outlet 513 through the mixing water channel 514; when the pure water kettle 1 and the heat preservation device 3 supply water to the instant heating body 2 together, the room temperature pure water and the warm water are pre-mixed in the mixing water channel 514 and then flow to the drain outlet 513. The pre-mixing of the room temperature pure water and the warm water in the mixing water channel 514 helps to balance the water temperature and water pressure, and effectively ensure the stability of the water outlet temperature and water flow rate of the instant heating body 2.

[0059] Regarding the assembly structure of the cold water pump 52 on the plate body 51, in a preferred embodiment, as shown in FIG. Figure 3 and Figure 6 As shown, the cold water channel 511 is provided with a pure water inlet 5111 and a cold water outlet 5112, and the mixed water channel 514 is provided with a cold water inlet 5141. The pure water inlet 5111 is connected to the kettle body outlet, and the cold water outlet 5112 is connected to the inlet end of the cold water pump 52, and the outlet end of the cold water pump 52 is connected to the cold water outlet 5112. Specifically, the inlet end and the outlet end of the cold water pump 52 can be inserted into the cold water outlet 5112 and the cold water inlet 5141 respectively. The cold water pump 52 spans the cold water channel 511 and the mixed water channel 514. The pure water output from the pure water kettle 1 enters the cold water channel 511 from the pure water inlet 5111, then enters the cold water pump 52 from the cold water outlet 5112, and then enters the mixed water channel 514 from the cold water inlet 5141, and finally is discharged from the drain outlet 513.

[0060] Regarding the assembly structure of the hot water pump 53 on the plate body 51, in a preferred embodiment, as shown in FIG. Figures 3 to 6 As shown, the apparatus further includes a connecting pipe 6, one end of which is a warm water inlet 61 connected to the heat-insulating water outlet, and the other end is a warm water outlet. The warm water outlet is connected to the inlet of the hot water pump 53 via an adapter 62. The hot water channel 512 is provided with a hot water inlet 5121, and the outlet of the hot water pump 53 is connected to the hot water inlet 5121. Specifically, the inlet and outlet of the hot water pump 53 can be inserted into the adapter 62 and the hot water inlet 5121 respectively. The hot water pump 53 spans the connecting pipe 6 and the hot water channel 512. The warm water output by the heat-insulating device 3 enters from one end of the connecting pipe 6, then enters the hot water pump 53 through the adapter 62 at the other end, then enters the hot water channel 512 from the hot water pump 53, then enters the mixed water channel 514, and finally is discharged from the drain outlet 513.

[0061] Further, if Figures 4 to 6 As shown, the plate body 51 is provided with an avoidance gap 515 at a position adjacent to the hot water inlet 5121, and the adapter 62 extends into the avoidance gap 515 and is adjacent to the hot water inlet 5121, so that the distance between the connecting pipe 6 and the mixed water channel 514 is small, which facilitates the direct connection of the two ends of the hot water pump 53 with the plate body 51 and the adapter 62 respectively, thereby improving assembly convenience, simplifying the water channel structure, and reducing the risk of water leakage.

[0062] In a preferred embodiment, the plate body 51 is placed horizontally, and the cold water pump 52 and the hot water pump 53 are both installed on the upper side of the plate body 51. It will be understood by those skilled in the art that, compared to placing the plate body 51 vertically and mounting the cold water pump 52 and the hot water pump 53 on the side of the plate body 51 or on the bottom of the plate body 51, the present application places the plate body 51 horizontally, and the cold water pump 52 and the hot water pump 53 are both installed on the upper side of the plate body 51. On the one hand, the cold water pump 52 and the hot water pump 53 are both installed on the same side of the plate body 51, making the overall structure of the integrated waterway board 5 compact and taking up less space during installation; on the other hand, the cold water pump 52 and the hot water pump 53 are both installed on the upper side of the plate body 51, so that the gravity of the cold water pump 52 and the hot water pump 53 can be used to press the positions where the cold water pump 52 and the hot water pump 53 are respectively connected to the plate body 51, which helps to improve the connection stability and sealing effect of the connection and reduce the risk of water leakage.

[0063] As a preferred embodiment of the present application, Figures 7 to 9 As shown, the tabletop water purifier further includes a water channel adapter 7, which is provided with a water passage cavity 71 and a pure water inlet 72, a kettle communication port 73, and a pure water outlet 74 respectively connected to the water passage cavity 71. The filter unit is connected to the pure water inlet 72, the kettle communication port 73 is connected to the kettle body inlet, and the pure water outlet 74 is connected to the cold water channel 511. The water channel adapter 7 is not only a transfer structure connecting the filter unit with the pure water kettle 1, but also a transfer structure connecting the pure water kettle 1 with the instant heating body 2, thereby improving the functional integration of the water channel adapter 7. When the pure water kettle 1 transports pure water to the instant heating body 2, the pure water first enters the water flow chamber 71 from the kettle connecting port 73. When the water flow in the water flow chamber 71 reaches a certain amount, it flows toward the pure water outlet 74. Therefore, the existence of the water flow chamber 71 can have a better stabilizing effect on the flow rate and pressure of the pure water entering from the pure water kettle 1, achieve stable pressure and flow rate, balance the water inlet pressure, and make the pure water flow rate of the pure water kettle 1 to the instant heating body 2 uniform and stable, effectively ensuring the stability of the water outlet temperature and water outlet flow of the instant heating body 2.

[0064] Further, if Figure 2 、 Figure 7 、 Figure 8 and Figure 9As shown, the desktop water purifier also includes a water level connecting pipe 8 for measuring the water level in the pure water kettle 1. The water channel adapter 7 is provided with a water level measuring port 75 connected to the water flow chamber 71, and the water level connecting pipe 8 is connected to the water level measuring port 75. Specifically, while the pure water produced by the filtration unit is transported toward the pure water kettle 1 through the water channel adapter 7, the pure water in the water flow chamber 71 also enters the water level connecting pipe 8 through the water level measuring port 75, so as to detect the water level of the pure water kettle 1 through the water level connecting pipe 8. The presence of the water flow chamber 71 can have a good stabilizing effect on the flow rate and pressure of the pure water entering from the pure water inlet 72, thereby achieving stable pressure and flow rate, balancing the pure water inlet pressure, and balancing the water pressure in the pure water kettle 1 and the water level connecting pipe 8, thereby minimizing the water level difference between the pure water kettle 1 and the water level connecting pipe 8, and effectively improving the accuracy of the water level detection in the pure water kettle 1 by the water level connecting pipe 8.

[0065] As a preferred embodiment of the present application, Figures 10 to 12 As shown, the desktop water purifier also includes a bracket 9, which is provided with a first installation cavity 92 and a second installation cavity 93 separated by a partition 91. The heat preservation device 3 is provided in the first installation cavity 92, and the integrated waterway plate 5 is provided in the second installation cavity 93. The pure water kettle 1 is located on the outside of the bracket 9. The bracket 9 is provided with a first avoidance gap 94 and a second avoidance gap 95. The kettle body outlet and the cold water channel 511 are connected at the first avoidance gap 94, and the heat preservation water outlet and the hot water channel 512 are connected at the second avoidance gap 95. It can be understood by those skilled in the art that, by providing the bracket 9, installation space and structural support can be provided for multiple accessories including the heat preservation device 3 and the integrated waterway plate 5, thereby improving installation stability and assembly efficiency.
