[0040] 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.

[0041] Reference Figures 1 to 6 As shown, a desktop water purifier provided in the present application includes a body 1 and a pure water kettle 2, a water kettle placement position is provided on the outer side of the body 1, and the pure water kettle 2 is detachably arranged at the water kettle placement position, a pure water preparation structure for preparing pure water and a water level connecting pipe 3 for measuring the water level of the pure water kettle 2 are provided in the body 1, and the desktop water purifier also includes a water path adapter 4 for connecting the pure water preparation structure with the pure water kettle 2, the water path adapter 4 is provided with a water inlet pressure stabilizing chamber 41 and a pure water inlet 431, a water kettle connecting port 421 and a connecting pipe outlet 432 respectively connected to the water inlet pressure stabilizing chamber 41, the pure water inlet 431 is connected to the pure water preparation structure, the water kettle connecting port 421 is connected to the pure water kettle 2, and the connecting pipe outlet 432 is connected to the water level connecting pipe 3.

[0042] Specifically, the present application schematically illustrates an embodiment in which the kettle placement position is located at the front side of the machine body 1 so that the pure water kettle 2 can be placed at the front side of the machine body 1, providing convenience for taking and placing the pure water kettle 2. When the pure water kettle 2 is placed at the kettle placement position, it is connected with the pure water production structure inside the machine body 1, so that the pure water produced by the pure water production structure can be transported to the pure water kettle 2 for storage, and at the same time transported to the water level connecting pipe 3, so as to detect the water level of the pure water kettle 2 through the water level connecting pipe 3. In addition, the present application does not limit the pure water production structure, for example, it can be a filtering structure capable of producing pure water, including but not limited to a reverse osmosis filter element, a composite filter element, etc.

[0043] In the desktop water purifier provided by the present application, the water path adapter 4 is used to connect the pure water production structure with the pure water kettle 2. The water path adapter 4 is provided with a water inlet pressure stabilizing chamber 41 and a pure water inlet 431, a kettle connecting port 421 and a connecting pipe outlet 432 respectively connected to the water inlet pressure stabilizing chamber 41. The pure water inlet 431 is connected to the pure water production structure, the kettle connecting port 421 is connected to the pure water kettle 2, and the connecting pipe outlet 432 is connected to the water level connecting pipe 3. Therefore, when the pure water production structure transports pure water to the pure water kettle 2, the pure water enters from the pure water inlet 431 and is first pre-stored in the water inlet pressure stabilizing chamber 41. When the water flow in the water inlet pressure stabilizing chamber 41 reaches a certain amount, the pure water is respectively It flows toward the kettle connecting port 421 and the connecting pipe outlet 432, and then enters the pure water kettle 2 and the water level connecting pipe 3 respectively, wherein the pure water entering the pure water kettle 2 is stored, and the pure water entering the water level connecting pipe 3 is used to detect the water level in the pure water kettle 2. The existence of the water inlet pressure stabilizing chamber 41 can have a good stabilizing effect on the flow rate and pressure of the pure water entering from the pure water inlet 431, achieve pressure stability and flow rate stability, balance the pure water inlet pressure, and balance the water pressure in the pure water kettle 2 and the water level connecting pipe 3 at the same time, reduce the water level difference between the pure water kettle 2 and the water level connecting pipe 3 as much as possible, and effectively improve the accuracy of the water level detection of the pure water kettle 2 by the water level connecting pipe 3.

[0044] As a preferred implementation of the present application, Figure 4 As shown, the water channel adapter 4 is further provided with a water outlet pressure stabilizing chamber 44 , and the water outlet pressure stabilizing chamber 44 connects the water inlet pressure stabilizing chamber 41 and the connecting pipe outlet 432 . Those skilled in the art can understand that the water outlet pressure-stabilizing chamber 44 connects the water inlet pressure-stabilizing chamber 41 and the connecting pipe outlet 432. In other words, the water outlet pressure-stabilizing chamber 44 constitutes an intermediate path for connecting the water inlet pressure-stabilizing chamber 41, so that when the pure water production structure transports pure water into the pure water kettle 2, the pure water enters from the pure water inlet 431 and is first pre-stored in the water inlet pressure-stabilizing chamber 41, and then flows from the water inlet pressure-stabilizing chamber 41 toward the kettle connecting port 421 and the water outlet pressure-stabilizing chamber 44 respectively. Therefore, the water inlet pressure-stabilizing chamber 41 can achieve initial pressure stabilization and flow rate stabilization for the pure water entering from the pure water inlet 431, and the water outlet pressure-stabilizing chamber 44 can stabilize the pressure and flow rate of the pure water again before entering the water level connecting pipe 3, so that the water flow is uniform and stable, thereby improving the balance of the water pressure in the pure water kettle 2 and the water level connecting pipe 3, and thereby effectively improving the accuracy of the water level detection in the pure water kettle 2 by the water level connecting pipe 3.

[0045] Furthermore, if Figure 4As shown, a pressure stabilizing hole 433 connected to the connecting pipe outlet 432 is provided on the wall of the water outlet pressure stabilizing chamber 44. When water flows from the water inlet pressure stabilizing chamber 41 into the water outlet pressure stabilizing chamber 44, the water will not rush directly to the connecting pipe outlet 432, but will flow slowly under the action of the pressure stabilizing hole 433, reducing water flow fluctuations and achieving pressure stability. Therefore, the pressure stabilizing hole 433 helps to further balance the water pressure of the water level connecting pipe 3 and the pure water kettle 2, so as to achieve the purpose of accurately detecting the water level of the pure water kettle 2.

[0046] Furthermore, if Figure 4 As shown, the outlet pressure stabilizing chamber 44 surrounds the outside of the inlet pressure stabilizing chamber 41 along the circumference of the inlet pressure stabilizing chamber 41. By making the outlet pressure stabilizing chamber 44 surround the outside of the inlet pressure stabilizing chamber 41, the space in the outlet pressure stabilizing chamber 44 is effectively increased, so that the pressure is stabilized by using a large space cavity, which helps to improve the pressure stabilization effect.

[0047] As a preferred implementation of the present application, Figure 2 , Figure 4 and Figure 5 As shown, the water channel adapter 4 is also provided with a pure water outlet 434 connected to the water inlet pressure stabilizing chamber 41, and the pure water outlet 434 is used to connect to the instant heating body of the desktop water purifier. The pure water outlet 434 is used to connect to the instant heating body of the desktop water purifier, so that the pure water kettle 2 can not only serve as a water flow transfer structure to guide the pure water produced by the pure water production structure into the pure water kettle 2, but also enable the pure water kettle 2 to transport pure water to the instant heating body through the water inlet pressure stabilizing chamber 41 and the pure water outlet 434, thereby forming a water path transfer structure to guide the pure water in the pure water kettle 2 into the instant heating body, thereby improving the functional integration of the water path adapter 4; in addition, because the pure water needs to pass through the water inlet pressure stabilizing chamber 41 when the pure water kettle 2 transports pure water to the instant heating body, therefore, under the action of the pressure stabilizing and flow rate stabilizing of the water inlet pressure stabilizing chamber 41, the pure water flow rate of the pure water kettle 2 to the instant heating body is uniform and stable, effectively ensuring the stability of the water outlet temperature and water outlet flow rate of the instant heating body.

[0048] Furthermore, if Figure 4 As shown, the pure water outlet 434 and the kettle connecting port 421 are respectively located at opposite ends of the water channel adapter 4, and the opening direction of the pure water outlet 434 is parallel to the opening direction of the kettle connecting port 421. It can be understood by those skilled in the art that by making the opening direction of the pure water outlet 434 parallel to the opening direction of the kettle connecting port 421, in the process of the pure water kettle 2 transporting pure water to the outlet, the pure water flows in a straight line as much as possible, reducing the turning phenomenon of the water flow, helping to shorten the flow path, so that the pure water flows stably into the instant heating body, and effectively ensuring the stability of the water outlet temperature and water outlet flow of the instant heating body.

[0049] Furthermore, if Figure 4 and Figure 5As shown, the water channel adapter 4 is provided with a pure water outlet pipe 435, one end of the pure water outlet pipe 435 is connected to the pure water outlet 434, and the other end extends toward the inside of the water inlet pressure stabilizing chamber 41. The pure water outlet pipe 435 is provided with a flow limiting hole 436 that connects to the water inlet pressure stabilizing chamber 41. Those skilled in the art can understand that, by connecting one end of the pure water outlet pipe 435 to the pure water outlet 434 and extending the other end toward the inside of the water inlet pressure stabilizing chamber 41, the pure water outlet pipe 435 is provided with a flow limiting hole 436 connected to the water inlet pressure stabilizing chamber 41. On the one hand, when the pure water kettle 2 outputs pure water to the instant heating body, the pure water can be stabilized in advance in the water inlet pressure stabilizing chamber 41 to achieve pressure stability and flow rate stability, and then further stabilized in the pure water outlet pipe 435 to improve the uniformity and stability of the pure water flow rate. In addition, through the setting of the flow limiting hole 436, the pure water output from the pure water kettle 2 to the instant heating body is limited, so that the flow limiting hole 436 can stabilize the water outlet flow rate, and then stabilize the water flow rate entering the instant heating body, thereby ensuring the stability of the water outlet temperature and water outlet flow rate of the instant heating body. Specifically, the flow limiting hole 436 can not only serve as a path for the water inlet pressure stabilizing chamber 41 to connect to the pure water outlet pipe 435, but also serve as a path for the water inlet pressure stabilizing chamber 41 to connect to the water outlet pressure stabilizing chamber 44, so that pure water can enter the water outlet pressure stabilizing chamber 44 from the flow limiting hole 436, reducing the number of openings inside the water path adapter 4, which helps to simplify the structure.

[0050] As a preferred implementation of the present application, Figure 2 and Figure 4 As shown, the pure water inlet 431 is located at the top of the water channel adapter 4, and the connecting pipe outlet 432 is located at the bottom of the water channel adapter 4. Through this arrangement, the pure water transported by the pure water production structure enters the water inlet pressure stabilizing chamber 41 from the top of the water channel adapter 4, and enters the water level connecting pipe 3 from the bottom of the water channel adapter 4, realizing the top-in and bottom-out structural design. Therefore, gravity can be used to make the pure water enter from the pure water inlet 431 and then be discharged from the connecting pipe outlet 432 with less obstruction, which helps to stabilize the water pressure, thereby improving the balance of the water pressure in the pure water kettle 2 and the water level connecting pipe 3, and thereby effectively improving the accuracy of the water level detection in the pure water kettle 2 by the water level connecting pipe 3.

[0051] As a preferred implementation of the present application, Figures 2 to 6As shown, the water circuit adapter 4 includes an upper cover 42 and a lower cover 43, the upper cover 42 and the lower cover 43 are connected and matched to form the water inlet pressure stabilizing chamber 41, the kettle connecting port 421 is arranged on the upper cover 42, and the pure water inlet 431 and the connecting pipe outlet 432 are arranged on the lower cover 43. By making the water circuit adapter 4 composed of the upper cover 42 and the lower cover 43 that are separately arranged, it is helpful to process and form, especially the processing and forming of the internal structure of the upper cover 42 and the lower cover 43, and the processing difficulty is reduced. In order to ensure the sealing of the splicing of the upper cover 42 and the lower cover 43, the two can be connected into one by welding.

[0052] Furthermore, if Figures 4 to 6 As shown, the upper cover 42 is provided with a first cylindrical docking portion 422, the lower cover 43 is provided with a second cylindrical docking portion 437 and a third cylindrical docking portion 438 located in the second cylindrical docking portion 437, the first cylindrical docking portion 422 is provided with a positioning flange 423 extending outwardly along the circumferential direction, the positioning flange 423 and the second cylindrical docking portion 437 are connected so that the first cylindrical docking portion 422 and the third cylindrical docking portion 438 are plugged and docked to cooperate to form the water inlet pressure stabilizing chamber 41. Specifically, when the positioning convex edge 423 and the second cylindrical docking portion 437 are connected to enable the first cylindrical docking portion 422 and the third cylindrical docking portion 438 to be plugged and docked, the interior of the first cylindrical docking portion 422 and the third cylindrical docking portion 438 cooperate to form an inlet water pressure stabilizing chamber 41, and the positioning convex edge 423 and the second cylindrical docking portion 437 cooperate to seal the space between the second cylindrical docking portion 437 and the third cylindrical docking portion 438 to form a water outlet pressure stabilizing chamber 44 surrounding the outer periphery of the water inlet pressure stabilizing chamber 41, and the water inlet pressure stabilizing chamber 41 and the water outlet pressure stabilizing chamber 44 are connected via the flow limiting hole 436 provided on the pure water outlet pipe 435.
