[0045] In the embodiment of the present application, a desktop water purifier is provided. For the convenience of explanation and understanding, the following contents provided in the present application are all explained on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only used as a specific example and schematic description, and cannot constitute a specific limitation of the technical solution provided in the present application.

[0046] Reference Figures 1 to 11 As shown, a desktop water purifier provided in the present application includes a body 1 and a raw water tank 2 installed on the body 1, the raw water tank 2 is provided with a plug connector 21 with a raw water outlet, the body 1 is provided with a water circuit adapter assembly 3 for plugging with the plug connector 21, the water circuit adapter assembly 3 includes a plug socket 31, a one-way valve 32, a cap 33 and a sealing body 34, the plug socket 31 is provided with a water flow chamber 311 and a connecting port 312 connected to the water flow chamber 311 and used to communicate with a water pump, the cap 33 covers the one-way valve 32 and limits it to the water flow chamber 311, the plug connector 21 is inserted on the cap 33, the cap 33 is provided with a water flow port 331 for connecting the raw water outlet and the one-way valve 32, and the sealing body 34 forms a seal between the plug connector 21 and the cap 33.

[0047] In the desktop water purifier provided by the present application, the socket 31 serves as the seat body of the water path adapter assembly 3, provides reliable bearing for the one-way valve 32, the cap 33 and the sealing body 34, and can also withstand the plugging force from the plug connector 21 when the raw water tank 2 is installed on the machine body 1; the water passage chamber 311 of the socket 31 can guide the raw water discharged from the raw water outlet of the raw water tank 2 toward the connecting port 312, so as to facilitate the water pump connected to the connecting port 312 to pump water; the cap 33 covers the one-way valve 32 and limits it to the water passage chamber 311, and provides a water passage port 331 for connecting the raw water outlet and the one-way valve 32, so that the raw water outlet is unidirectionally connected to the water passage chamber 311 through the one-way valve 32, that is, the raw water tank 2 can only drain water to the water passage chamber 311, and the water passage chamber 311 cannot drain water to the water passage port 331, thereby preventing After the raw water tank 2 is removed from the body 1, the water chamber 311 is prevented from leaking upward. Moreover, when pumping water, it is only necessary to use the suction force of the water pump to generate negative pressure in the raw water tank 2, so that the raw water can push the one-way valve 32 to open and inject water into the water chamber 311. When the water pump stops and the suction force disappears, the one-way valve 32 will automatically reset to an unstressed state to cut off the connection between the raw water outlet and the water chamber 311. The structure is simple, easy to operate, and the raw water outlet is controllable; the plug connector 21 is inserted on the cap 33, and the sealing body 34 forms a seal between the plug connector 21 and the cap 33 to ensure that the raw water discharged from the raw water outlet completely enters the water chamber 311 and is discharged from the connecting port 312, effectively preventing the raw water from leaking to the outside of the body 1; the water path adapter assembly 3 has fewer overall accessories, a simple structure, and is easy to install.

[0048] Specifically, when the raw water tank 2 is installed in place on the body 1, the plug connector 21 is inserted above the cap 33, and the water outlet 331 connects the raw water outlet with the water inlet end of the one-way valve 32. At this time, the sealing body 34 forms a seal between the plug connector 21 and the cap 33. When the water pump connected to the connecting port 312 is running for suction, the raw water in the raw water tank 2 is pressurized to open the one-way valve 32, and the raw water flows toward the connecting port 312 through the water chamber 311 and is sucked by the water pump.

[0049] It should be noted that the present application does not specifically limit the installation direction of the raw water tank 2 on the body 1 and the plugging direction of the plug connector 21 and the water circuit adapter assembly 3. For ease of installation, the installation direction of the raw water tank 2 on the body 1 and the plugging direction of the plug connector 21 and the water circuit adapter assembly 3 can be the same direction. In a preferred embodiment, Figures 1 to 4 and Fig.11As shown, multiple plug connectors 21 can be set at the bottom of the raw water tank 2, and the raw water tank 2 is installed on the body 1 from top to bottom, so that the plug connector 21 is inserted into the water circuit adapter assembly 3 from top to bottom.

When the cap 33 covers the one-way valve 32 in the water chamber 311, the snap protrusion 335 cooperates with the snap hole 318 to achieve detachable fixation of the cap 33 and the socket 31, preventing the cap 33 from shifting up and down. On the basis of realizing the limitation of the cap 33, the reliability of the cap 33 limiting the one-way valve 32 is also improved.

[0053] As a preferred implementation of the present application, Figure 4 , Figure 8 and Fig. 9 As shown, the sealing body 34 includes a mounting portion 341 and a sealing portion 342 connected to each other, the mounting portion 341 is connected to the cap 33, and the sealing portion 342 forms a seal between the cap 33 and the outer wall of the plug connector 21. Specifically, the mounting portion 341 is provided to facilitate the fixed installation of the sealing body 34 on the cap 33 to prevent the sealing body 34 from being brought out when the plug connector 21 is inserted or removed. After the mounting portion 341 is installed in place on the cap 33, the sealing portion 342 is located on the inner side of the side wall 333 of the cap 33 to form a seal between the cap 33 and the outer wall of the plug connector 21 when the plug connector 21 is inserted.

[0054] In a preferred embodiment, Figure 8 and Fig. 9As shown, the sealing portion 342 is provided with a plurality of sealing lips 3421 arranged at intervals along the axial direction, and the sealing lips 3421 abut against the plug connector 21. It can be understood by those skilled in the art that the plurality of sealing lips 3421 abut against the plug connector 21 to form a multi-line seal, which effectively improves the sealing effect of the sealing portion 342 and reduces the risk of water leakage between the cap 33 and the plug connector 21. The present application schematically illustrates an embodiment in which the sealing portion 342 is provided with two sealing lips 3421, and the two sealing lips 3421 abut against the plug connector 21 in the upper and lower directions to form two seals. Of course, the sealing lips 3421 can also be other suitable numbers, which are not limited here.
