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.

[0047] Reference Figures 1 to 4 As shown, a desktop water purifier provided in the present application includes a body and a raw water tank 1, the body is provided with a water tank seat 2 for supporting the raw water tank 1 and a water channel adapter assembly 4 for docking and communicating with the water outlet of the raw water tank 1, the body includes a vertical back panel 3, the water tank seat 2 has a first installation stroke and a second installation stroke, the first installation stroke and the second installation stroke are arranged at an angle, and the water tank seat 2 is installed on the main board 31 through the first installation stroke and the second installation stroke in sequence.

[0048] In the tabletop water purifier provided by the present application, the water tank seat 2 serves as the seat of the raw water tank 1, providing reliable support for the installation of the raw water tank 1 on the machine body. When the raw water tank 1 is installed on the water tank seat 2, the water channel adapter is docked with the raw water tank 1 and can guide the raw water in the raw water tank 1 to the downstream water channel components; the water tank seat 2 is installed on the vertical back plate 3 and the water channel adapter component 4 is pressed downward on the vertical back plate 3. In other words, the water tank seat 2 can be used to carry the raw water tank 1, and can also use the connection with the vertical back plate 3 to press and fix the water channel adapter component 4, thereby achieving The water tank seat 2 has multiple functions, improves the integration of component functions, helps to simplify the structure, saves the cost of accessories, and helps to ensure the installation firmness of the water circuit adapter assembly 4 on the machine body, thereby improving the sealing of the original water tank 1 and the water circuit adapter assembly 4 in the docking connection state, greatly reducing the risk of water leakage; in addition, when the original water tank 1 is removed from the water tank seat 2 and separated from the water circuit adapter assembly 4, the water tank seat 2 presses the water circuit adapter assembly 4, effectively reducing the risk of the original water tank 1 driving the water circuit adapter assembly 4 to shift. The water tank seat 2 is installed on the vertical backboard 3 through the first installation stroke and the second installation stroke in sequence, and the first installation stroke and the second installation stroke are arranged at an angle. In other words, the water tank seat 2 needs two strokes in different directions to be assembled in place, and the assembly stability is higher. Of course, the water tank seat 2 also needs to move in the opposite direction of the two strokes to be separated from the vertical backboard 3, so that the risk of the water tank seat 2 automatically separating from the vertical backboard 3 is greatly reduced, and the pressing effect of the water circuit adapter assembly 4 is reliably ensured.

[0049] Regarding the specific structure of the vertical backboard 3, as a preferred embodiment of the present application, as follows Figures 4 to 6 As shown, the vertical backboard 3 includes a main board body 31 and a bearing portion 32.

The main board body 31 extends in the vertical direction, and the bearing portion 32 is connected to the side of the main board body 31, which expands the extension area of ​​the vertical backboard 3 in the horizontal direction, creating reasonable conditions for installing the water channel adapter assembly 4 and the water tank seat 2. The water tank seat 2 is installed on the main board body 31 and presses the water channel adapter assembly 4 on the bearing portion 32. The setting of the bearing portion 32 provides a bearing space for the water channel adapter assembly 4, and facilitates the water tank seat 2 to press the water channel adapter assembly 4 above the bearing portion 32. At the same time, it is also convenient for the water channel adapter assembly 4 to form a reaction force on the water tank seat 2, and together with the water tank seat 2, the raw water tank 1 is carried to ensure that the raw water tank 1 is reliably installed.

[0050] As a preferred embodiment of this implementation, Figure 5 and Figure 6As shown, the bearing portion 32 is provided with a downwardly recessed accommodating chamber 321, the waterway adapter assembly 4 is installed in the accommodating chamber 321 and supported by the bottom surface of the accommodating chamber 321, and the top surface of the waterway adapter assembly 4 is higher than the top surface of the bearing portion 32 and is pressed by the water tank seat 2. It can be understood by those skilled in the art that the waterway adapter assembly 4 is installed in the accommodating chamber 321 and supported by the bottom surface of the accommodating chamber 321, so that the waterway adapter assembly 4 forms a partially hidden structure design, and does not protrude too high from the top surface of the bearing portion 32, which not only helps to save installation space, but also helps to lower the center of gravity of the whole machine and improve stability. In addition, by providing the bearing portion 32 with a downwardly recessed accommodating chamber 321, it is also convenient to set a notch on the wall of the accommodating chamber 321 to avoid the water outlet of the waterway adapter, so that the downstream waterway components can be connected to the waterway adapter assembly 4 below the bearing portion 32.

[0051] The present application does not limit the installation direction of the water tank seat 2. Preferably, the water tank seat 2 performs the first installation stroke in the horizontal direction to abutting position against the main board 31, and the water tank seat 2 performs the second installation stroke vertically downward from the abutting position to a pressing position where the water channel adapter assembly 4 is pressed against the bearing portion 32. When installing the water tank seat 2, it is necessary to push the water tank seat 2 horizontally forward on one side of the vertical backboard 3 until it abuts against the main board 31, and then move the water tank seat 2 vertically downward so that the water tank seat 2 presses the water channel adapter assembly 4. At this time, the water tank seat 2 is installed in place, and the water channel adapter assembly 4 is limited at the same time.

[0052] Further, regarding the connection method between the water tank seat 2 and the main board body 31, in a preferred embodiment, as Figure 6 , Figure 8 , Fig. 9 and Fig.10 As shown, the main board 31 is provided with an avoidance hole 311, and the side wall of the water tank seat 2 is provided with a buckle 21; in the abutting position, the buckle 21 extends into the avoidance hole 311; in the pressing position, the buckle 21 is snapped onto the surface of the main board 31 below the avoidance hole 311.
