Description

Technical Field

[0001] This application relates to the field of water purifier technology, specifically to a countertop water purifier. Background Technology

[0002] With economic development and improved living standards, consumers are paying more and more attention to healthy water and drinking water, and their requirements for water use are also getting higher and higher. As a water treatment device that can deeply filter and purify water according to its usage requirements, water purifiers are gaining increasing recognition and favor from consumers.

[0003] Countertop water purifiers are a common type of water purifier on the market. Compared to floor-standing and under-sink models, countertop water purifiers are smaller and can be placed directly on a countertop, making them convenient to use and popular with consumers. With technological advancements, countertop water purifiers are increasingly capable of performing more and more functions. However, they also require multiple water circuit components, such as filter cartridges, water pumps, water control valves, heating elements, raw water tanks, and purified water jugs. Each water circuit component does not operate independently but needs to be connected to at least one other component. For example, the booster pump pumps raw water from the tank into the filter cartridge, the purified water produced by the filter cartridge is then diverted to the heating element and purified water jug, and the water control valve controls the flow of water. Therefore, in addition to these water circuit components, countertop water purifiers also require a water circuit board and water pipes. The water circuit board is a crucial component for connecting these water circuit components; raw water, purified water, and wastewater all flow through it. However, in most existing countertop water purifiers, the water circuit components are connected to the water circuit board via water pipes, resulting in a large number of pipe fittings installed on a single water circuit board. This makes the assembly process complex, installation difficult, and poses a significant risk of leakage. Utility Model Content

[0004] This application provides a countertop water purifier to improve the technical problems of existing countertop water purifiers, which have a large number of water pipe joints installed on the water circuit board, resulting in complicated assembly process, difficult installation, and a high risk of water leakage.

[0005] The technical solution adopted in this application is as follows:

[0006] A countertop water purifier includes a water circuit board, a filter element, a water distributor, and a booster pump. The water circuit board has a filter element mounting position, a water distributor mounting position, and a booster pump mounting position. The filter element is installed in the filter element mounting position, the water distributor is installed in the water distributor mounting position, and the booster pump is installed in the booster pump mounting position. The booster pump is connected to the filter element through the water circuit board, and the filter element is connected to the water distributor through the water circuit board. The water distributor is used to divert and discharge the pure water output from the filter element.

[0007] In this technical solution, the filter element is installed at the filter element mounting position, the water distribution component is installed at the water distribution component mounting position, and the booster pump is installed at the booster pump mounting position. This integrates the filter element, water distribution component, and booster pump onto the water circuit board. The filter element, water distribution component, and booster pump do not need to be connected to the water circuit board through water pipes and water circuit joints, reducing the use of pipe fittings. The machine assembly is more compact, which helps to simplify the assembly process and water circuit structure, reduce the installation difficulty, and the fewer pipe fittings on the water circuit board, the more it helps to reduce the risk of water leakage.

[0008] The booster pump is equipped with an inlet pipe and an outlet pipe. The inlet pipe has a pump water inlet, and the outlet pipe has a pump water outlet. The booster pump mounting position is equipped with a pump inlet port and a pump outlet port. The inlet pipe is inserted into the pump inlet port, and the outlet pipe is inserted into the pump outlet port.

[0009] In this technical solution, the inlet pipe and the outlet pipe are respectively inserted into the pump inlet and the pump outlet, realizing direct connection between the booster pump and the water circuit board. This makes the booster pump easy to install and remove from the water circuit board and facilitates maintenance. In a preferred embodiment, the booster pump can be installed above the water circuit board. This allows the weight of the booster pump to press the inlet pipe and the outlet pipe tightly against the water circuit board, improving the sealing performance of the connection between the inlet pipe and the pump inlet and the outlet pipe and the pump outlet.

[0010] The filter element is provided with a raw water inlet, a pure water inlet, and a wastewater inlet. The raw water inlet has a raw water inlet, the pure water inlet has a pure water outlet, and the wastewater inlet has a wastewater outlet. The filter element mounting position is provided with a raw water port, a pure water port, and a wastewater port. The raw water inlet is inserted into the raw water port, the pure water inlet is inserted into the pure water port, and the wastewater inlet is inserted into the wastewater port.

[0011] In this technical solution, the raw water pipe is inserted into the raw water inlet, the pure water pipe is inserted into the pure water inlet, and the wastewater pipe is inserted into the wastewater inlet, realizing direct connection between the filter element and the water circuit board. Since the filter element is a consumable that needs to be replaced regularly, the method of connecting the filter element to the water circuit board improves the ease of disassembly and assembly of the filter element on the water circuit board, simplifies the replacement process, and reduces the difficulty of replacement.

[0012] The water distribution component is provided with an inlet connector and an outlet connector. The inlet connector is provided with a pure water inlet, and the outlet connector is provided with a pure water outlet. The installation position of the water distribution component is provided with an inlet connector and an outlet connector. The inlet connector is inserted into the inlet connector, and the outlet connector is inserted into the outlet connector.

[0013] In this technical solution, by inserting the inlet connector into the inlet water distribution port and the outlet connector into the outlet water distribution port, the water distribution component and the water circuit board are directly connected, which facilitates the installation of the water distribution component. In a preferred embodiment, the water distribution component can also be installed on the top of the water circuit board, so that the water distribution component is installed from top to bottom, and the water circuit board is used to position the water distribution component to prevent the water distribution component from shifting to the left or right.

[0014] The countertop water purifier also includes a water pump and a heating element. The water distribution component can supply water to the heating element through the water circuit board and the water pump. The water circuit board is provided with a water pump inlet and a water supply channel that connects the water outlet inlet to the water pump inlet. The water pump is plugged into the water pump inlet.

[0015] In this technical solution, the water pump is integrated into the water circuit board by plugging it into the water pump socket. The water pump does not need to be connected to the water circuit board through water pipes and water circuit connectors, which reduces the use of pipe fittings, further simplifies the assembly process and water circuit structure, reduces installation difficulty, and reduces the risk of water leakage.

[0016] The water circuit board is provided with a first pure water channel for receiving pure water produced by the filter element and a second pure water channel for conveying pure water to the water distribution component. The tabletop water purifier also includes a bridging component, which is provided with a water passage. The bridging component is connected to the water circuit board and connects the first pure water channel and the second pure water channel through the water passage.

[0017] In this technical solution, the water circuit board connects the filter element and the water distribution component through a first pure water channel, a bridging component, and a second pure water channel. Compared to using a single pure water channel to connect the filter element and the water distribution component, the first pure water channel can be expanded into a water circuit to meet other functions when needed, allowing the first pure water channel to selectively connect to the second pure water channel and other water circuits. In addition, from a manufacturing perspective, compared to manufacturing a long and winding pure water channel, manufacturing two short pure water channels and connecting them through a bridging component is a simpler process.

[0018] The tabletop water purifier also includes a wastewater valve. The water circuit board is provided with a wastewater inlet and a wastewater channel that connects the wastewater outlet of the filter element to the wastewater inlet. The inlet of the wastewater valve is plugged into the wastewater inlet.

[0019] In this technical solution, by connecting the inlet of the wastewater valve to the wastewater inlet socket, the inlet does not need to be connected to the water circuit board through water pipes and water circuit connectors, reducing the use of pipe fittings, further simplifying the assembly process and water circuit structure, reducing installation difficulty, and reducing the risk of leakage.

[0020] The water circuit board is provided with a raw water inlet, a wastewater outlet, a wastewater return outlet, and a wastewater return channel that connects the wastewater outlet and the wastewater return outlet. The tabletop water purifier also includes a raw water tank. The outlet of the wastewater valve is connected to the wastewater outlet. The wastewater return outlet is connected to the raw water tank through a first water circuit connector, which is also connected to the wastewater return outlet. The raw water tank is connected to the booster pump through a second water circuit connector, which is also connected to the raw water inlet.

[0021] In this technical solution, by connecting the outlet of the wastewater valve to the wastewater inlet, the outlet does not need to be connected to the water circuit board through water pipes and water circuit connectors. The first water circuit connector is connected to the wastewater return inlet, and the second water circuit connector is connected to the raw water inlet. This reduces the use of pipe fittings, further simplifies the assembly process and water circuit structure, reduces installation difficulty, and reduces the risk of leakage.

[0022] The water circuit board is equipped with a raw water TDS detector and a pure water TDS detector. The raw water TDS detector is used to detect the TDS value of the raw water delivered from the raw water tank to the booster pump, and the pure water TDS detector is used to detect the TDS value of the pure water delivered from the filter element to the water distributor.

[0023] In this technical solution, the raw water TDS detector and the pure water TDS detector are directly integrated and installed on the water circuit board, which further enriches the integrated functions of the water circuit board. The raw water TDS detector and the pure water TDS detector can respectively perform TDS detection on the raw water and pure water flowing through the water circuit board.

[0024] The countertop water purifier includes a main support and a base plate. The main support and the base plate form a receiving cavity. The water circuit board is disposed in the receiving cavity and fixedly connected to the main support. The filter element, the water distribution component, and the booster pump are connected to the upper side of the water circuit board. The main support is provided with a filter element limiting part for limiting the filter element and a pump limiting part for limiting the booster pump. The water circuit board is provided with a fixing part for fixing the water distribution component.

[0025] In this technical solution, the filter element, water distribution component, and booster pump are connected to the upper side of the water circuit board. The gravity of the filter element, water distribution component, and booster pump is used to press the water circuit board, improving the sealing performance of each component's connection with the water circuit board and reducing the risk of leakage.

[0026] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows: the filter element is installed at the filter element installation position, the water distribution component is installed at the water distribution component installation position, and the booster pump is installed at the booster pump installation position, so that the filter element, water distribution component, and booster pump are integrated and installed on the water circuit board. The filter element, water distribution component, and booster pump do not need to be connected to the water circuit board through water pipes and water circuit joints, which reduces the use of pipe fittings, makes the machine assembly more compact, helps to simplify the assembly process and water circuit structure, reduces the installation difficulty, and the fewer pipe fittings on the water circuit board, the more it helps to reduce the risk of water leakage.

[0059] In the embodiments of this application, a countertop water purifier is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0060] Reference Figures 1 to 9As shown, the countertop water purifier provided in this application includes a water circuit board 1, a filter element 2, a water distribution component 3, and a booster pump 4. The water circuit board 1 has a filter element mounting position, a water distribution component mounting position, and a booster pump mounting position. The filter element 2 is installed in the filter element mounting position, the water distribution component 3 is installed in the water distribution component mounting position, and the booster pump 4 is installed in the booster pump mounting position. The booster pump 4 is connected to the filter element 2 through the water circuit board 1, and the filter element 2 is connected to the water distribution component 3 through the water circuit board 1. The water distribution component 3 is used to divert and discharge the pure water output by the filter element 2.

[0061] The countertop water purifier of this application has a booster pump 4 connected to a filter element 2 via a water circuit board 1. The booster pump 4 can deliver raw water to the filter element 2 for filtration through the water circuit board 1. The filter element 2 is connected to a water distributor 3 through the water circuit board 1. The purified water produced by the filter element 2 is delivered to the water distributor 3 through the water circuit board 1. The water distributor 3 then diverts the purified water out, for example, it can divert the purified water to the heating element for heating, or it can divert it to a purified water pitcher for storage, or it can directly deliver it to the faucet. Figure 1 and Figure 2 As shown, an embodiment is illustrated where a pure water pitcher 5 is installed on the water distribution component 3, and the water filtered by the filter element 2 can enter the pure water pitcher 5 through the water distribution component 3.

[0062] In this technical solution, filter element 2 is installed at the filter element mounting position, water distribution component 3 is installed at the water distribution component mounting position, and booster pump 4 is installed at the booster pump mounting position, so that filter element 2, water distribution component 3, and booster pump 4 are integrated and installed on water circuit board 1. Filter element 2, water distribution component 3, and booster pump 4 do not need to be connected to water circuit board 1 through water pipes and water circuit joints, which reduces the use of pipe fittings, makes the machine assembly more compact, helps to simplify the assembly process and water circuit structure, and reduces the installation difficulty. The fewer pipe fittings on water circuit board 1, the more it helps to reduce the risk of water leakage.

[0063] As a preferred embodiment of this application, such as Figure 3 , Figure 4 and Figure 6As shown, the booster pump 4 is provided with an inlet pipe 41 and an outlet pipe 42. The inlet pipe 41 is provided with a pump water inlet, and the outlet pipe 42 is provided with a pump water outlet. The booster pump mounting position is provided with a pump inlet port 111 and a pump outlet port 112. The inlet pipe 41 is inserted into the pump inlet port 111, and the outlet pipe 42 is inserted into the pump outlet port 112. The booster pump 4 draws water in through the inlet pipe 41 and discharges it through the outlet pipe 42. Specifically, the inlet pipe 41 and the outlet pipe 42 can be inserted into the pump inlet port 111 and the pump outlet port 112, respectively, and sealing bodies are installed in the pump inlet port 111 and the pump outlet port 112. The direct connection between the booster pump 4 and the water circuit board 1 makes it easy to install and remove the booster pump 4 on the water circuit board 1 and facilitates maintenance. In a preferred embodiment, the booster pump 4 can be installed above the water circuit board 1. This allows the weight of the booster pump 4 to press the inlet pipe 41 and the outlet pipe 42 against the water circuit board 1, improving the sealing performance of the connection between the inlet pipe 41 and the pump inlet port 111 and the outlet pipe 42 and the pump outlet port 112.

[0064] As a preferred embodiment of this application, such as Figure 4 , Figure 6 and Figure 8 As shown, the filter element 2 is provided with a raw water inlet 21, a pure water inlet 22, and a wastewater inlet 23. The raw water inlet 21 is provided with a raw water inlet, the pure water inlet 22 is provided with a pure water outlet, and the wastewater inlet 23 is provided with a wastewater outlet. The raw water output by the booster pump 4 enters the filter element 2 through the raw water inlet, the pure water produced by the filter element 2 is discharged through the pure water outlet, and the wastewater produced is discharged through the wastewater outlet. The filter element installation position is provided with a raw water inlet 121, a pure water inlet 122, and a wastewater inlet 123. The raw water inlet 21 is inserted into the raw water inlet 121, the pure water inlet 22 is inserted into the pure water inlet 122, and the wastewater inlet 23 is inserted into the wastewater inlet 123. The diagram shows the raw water inlet 21, pure water inlet 22, and wastewater inlet 23 arranged in a triangular pattern, which helps save space and improve connection stability. The raw water inlet 121, pure water inlet 122, and wastewater inlet 123 should also be arranged in a triangular pattern on the water circuit board 1. In this technical solution, the raw water inlet 21 is inserted into the raw water inlet 121, the pure water inlet 22 is inserted into the pure water inlet 122, and the wastewater inlet 23 is inserted into the wastewater inlet 123, realizing direct connection between the filter element 2 and the water circuit board 1. Since the filter element 2 is a consumable that needs to be replaced regularly, the connection between the filter element 2 and the water circuit board 1 improves the ease of installation and removal of the filter element 2 on the water circuit board 1, simplifies the replacement process, and reduces the difficulty of replacement.

[0065] As a preferred embodiment of this application, such as Figure 4 , Figure 6 and Figure 9 As shown, the water distribution component 3 has an inlet connector 31 and an outlet connector 32. The inlet connector 31 has a pure water inlet, and the outlet connector 32 has a pure water outlet. The water distribution component mounting position has an inlet connector 131 and an outlet connector 132. The inlet connector 31 is inserted into the inlet connector 131, and the outlet connector 32 is inserted into the outlet connector 132. It should be noted that the pure water outlet is only one of the water outlets of the water distribution component 3. In other embodiments, the water distribution component 3 may also have other water outlets. These water outlets can discharge water through the water circuit board 1 or directly to the water circuit components. In this technical solution, by inserting the inlet connector 31 into the inlet water distribution port 131 and the outlet connector 32 into the outlet water distribution port 132, the water distributor 3 and the water circuit board 1 are directly connected, facilitating the installation of the water distributor 3. In a preferred embodiment, the water distributor 3 can also be installed on top of the water circuit board 1, with the water distributor 3 installed from top to bottom. The water circuit board 1 is used to position the water distributor 3, preventing it from shifting left or right. In the aforementioned embodiment where a pure water pitcher 5 is installed on the water distributor 3, the water filtered by the filter element 2 can directly enter the pure water pitcher 5 through the water distributor 3. The pure water in the pure water pitcher 5 can also be transported to other components such as the heating element through the outlet connector 32 of the water distributor 3 and the water circuit board 1.

[0066] Furthermore, such as Figure 2 , Figure 3 and Figure 6 As shown, the countertop water purifier also includes a water pump 6 and a heating element 7. The water distribution component 3 can supply water to the heating element 7 through the water circuit board 1 and the water pump 6. The water circuit board 1 is provided with a water pump inlet 14 and a water supply channel connecting the water outlet inlet 132 to the water pump inlet 14. The water pump 6 is plugged into the water pump inlet 14. Specifically, when the water pump 6 pumps water, the pure water filtered by the filter element 2 is first delivered to the water distribution component 3, and then enters the heating element 7 through the water distribution component 3 and the water pump 6. In this technical solution, by plugging the water pump 6 into the water pump inlet 14, the water pump 6 is integrated and installed on the water circuit board 1. The water pump 6 does not need to be connected to the water circuit board 1 through water pipes and water circuit connectors, reducing the use of pipe fittings, further simplifying the assembly process and water circuit structure, reducing installation difficulty, and reducing the risk of leakage.

[0067] Furthermore, the water circuit board 1 is provided with a first pure water channel for receiving the pure water produced by the filter element 2 and a second pure water channel for conveying pure water to the water distribution component 3, such as... Figure 5As shown, the countertop water purifier also includes a bridging component 8. The bridging component 8 has a water passage, and it is connected to the water circuit board 1, connecting the first pure water channel and the second pure water channel through the water passage. In this technical solution, the water circuit board 1 connects the filter element 2 and the water distributor 3 through the first pure water channel, the bridging component 8, and the second pure water channel. Compared to using a single pure water channel to connect the filter element 2 and the water distributor 3, the first pure water channel can be expanded to meet other functions when needed, allowing the first pure water channel to selectively connect to the second pure water channel and other water channels. Furthermore, from a manufacturing perspective, manufacturing two short pure water channels and connecting them through the bridging component 8 is simpler than manufacturing a long and winding pure water channel. Specifically, the bridging component 8 can be fixed to the water circuit board 1 with screws to ensure that the bridging component 8 can be securely installed on the water circuit board 1.

[0068] As a preferred embodiment of this application, such as Figure 5 and Figure 7 As shown, the countertop water purifier also includes a wastewater valve 9. The water circuit board 1 is provided with a wastewater inlet 15 and a wastewater channel connecting the wastewater outlet of the filter element 2 to the wastewater inlet 15. The inlet of the wastewater valve 9 is plugged into the wastewater inlet 15. The wastewater valve 9 is used to control the opening and closing of the wastewater discharge path produced by the filter element 2. When the wastewater valve 9 is open, wastewater can be discharged. In this technical solution, by plugging the inlet of the wastewater valve 9 into the wastewater inlet 15, the inlet does not need to be connected to the water circuit board 1 through water pipes and water circuit connectors, reducing the use of pipe fittings, further simplifying the assembly process and water circuit structure, reducing installation difficulty, and reducing the risk of leakage.

[0069] Furthermore, such as Figure 5 and Figure 7As shown, the water circuit board 1 is provided with a raw water inlet 16, a wastewater outlet 17, a wastewater return outlet 18, and a wastewater return channel that connects the wastewater outlet 17 and the wastewater return outlet 18. The tabletop water purifier also includes a raw water tank 100. The outlet of the wastewater valve 9 is connected to the wastewater outlet 17. The wastewater return outlet 18 is connected to the raw water tank 100 through a first water circuit connector 200. The first water circuit connector 200 is connected to the wastewater return outlet 18. The raw water tank 100 is connected to the booster pump 4 through a second water circuit connector 300. The second water circuit connector 300 is connected to the raw water inlet 16. Specifically, the raw water tank 100 can store tap water. The booster pump 4 can draw water from the raw water tank 100 and enter the filter element 2 through the water circuit board 1. The wastewater produced by the filter element 2 can be controlled by the wastewater valve 9 to return to the raw water tank 100, thereby realizing wastewater recycling. By connecting the outlet of the wastewater valve 9 to the wastewater inlet 15, the outlet does not need to be connected to the water circuit board 1 through water pipes and water circuit connectors. The first water circuit connector 200 is connected to the wastewater return inlet 18, and the second water circuit connector 300 is connected to the raw water inlet 16. This reduces the use of pipe fittings, further simplifies the assembly process and water circuit structure, reduces installation difficulty, and reduces the risk of leakage.

[0070] Furthermore, such as Figure 5 As shown, the water circuit board 1 is equipped with a raw water TDS detector 400 and a pure water TDS detector 500. The raw water TDS detector 400 is used to detect the TDS value of the raw water delivered from the raw water tank 100 to the booster pump 4, and the pure water TDS detector 500 is used to detect the TDS value of the pure water delivered from the filter element 2 to the water distributor 3. In this technical solution, the raw water TDS detector 400 and the pure water TDS detector 500 are directly integrated and installed on the water circuit board 1, further enriching the integrated functions of the water circuit board 1. The raw water TDS detector 400 and the pure water TDS detector 500 can respectively detect the TDS of the raw water and pure water flowing through the water circuit board 1 and feed back to the control unit of the countertop water purifier for TDS detection.

[0071] As a preferred embodiment of this application, such as Figure 2 , Figure 3 and Figure 4As shown, the countertop water purifier includes a main support 600 and a base plate 700. The main support 600 and the base plate 700 form a receiving cavity. The water circuit plate 1 is disposed in the receiving cavity and fixedly connected to the main support 600. The filter element 2, the water distributor 3, and the booster pump 4 are connected to the upper side of the water circuit plate 1. The main support 600 is provided with a filter element limiting part for limiting the filter element 2 and a pump limiting part 602 for limiting the booster pump 4. The water circuit plate 1 is provided with a fixing part 603 for fixing the water distributor 3. In this technical solution, the filter element 2, the water distributor 3, and the booster pump 4 are connected to the upper side of the water circuit plate 1. The gravity of the filter element 2, the water distributor 3, and the booster pump 4 presses the water circuit plate 1, improving the sealing performance of each component's connection with the water circuit plate 1 and reducing the risk of leakage. Preferably, the filter element limiting part can be provided with an assembly cavity 601, in which the filter element 2 is installed. The assembly cavity 601 limits the filter element 2, ensuring stable installation and facilitating plug-in replacement. Since the booster pump 4 is a heavy water system component, the pump limiting part 602 limits its position, ensuring stable installation. Specifically, the booster pump 4 can be fixed to the pump limiting part 602 with screws. The water distribution component 3 can be fixed to the fixing part 603 with screws.
