Description

Technical Field

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

[0002] A countertop water purifier is a small household water purification device used to filter and purify water to meet safe and healthy drinking standards. As people increasingly value the health of their drinking water, countertop water purifiers are gradually becoming everyday necessities.

[0003] A common type of multi-functional countertop water purifier on the market features water filtration, heating, and ice water making. The ice water making function is primarily achieved through an electronic ice tank. In this technology, the countertop water purifier uses a solenoid valve to control the supply of purified water from the filter cartridge to the electronic ice tank. Water production and replenishment occur simultaneously. However, generally, the better the filter cartridge's filtration efficiency, the slower the water production speed and the longer the replenishment time. Furthermore, air from the filtration process can easily be introduced into the electronic ice tank, leading to higher water levels and pressure, which can prevent the ice tank from filling completely and thus limit its ice water making capacity. Inaccurate water level detection within the ice tank can also occur. Utility Model Content

[0004] This application provides a countertop water purifier to solve the technical problems in existing countertop water purifiers with electronic ice tanks, such as the long time required to replenish water to the electronic ice tank during the water production process of the filter cartridge, and the easy introduction of air, which prevents the electronic ice tank from being fully filled with water.

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

[0006] A countertop water purifier includes a filter cartridge, a pure water pitcher, an electronic ice tank, and a cold water pump. The pure water outlet of the filter cartridge is connected to the pure water pitcher, and the cold water pump is connected to the ice water outlet of the electronic ice tank. The cold water pump is configured as a bidirectional check pump that cuts off the internal water flow channel when the power is off. The pure water pitcher is connected to the water inlet of the electronic ice tank, so that while the cold water pump draws water from the electronic ice tank, the pure water pitcher replenishes water to the electronic ice tank, thereby maintaining the electronic ice tank in a full water state.

[0007] The countertop water purifier provided in this application also includes the following additional technical features:

[0008] Both the water inlet and the ice water outlet are located at the top of the electronic ice tank. The ice water outlet is connected to a suction pipe, which is inserted into the electronic ice tank and extends toward the bottom of the electronic ice tank.

[0009] The outer wall of the water suction pipe and the inner wall of the ice water outlet form a suction gap for the cold water pump to draw gas from the electronic ice chamber.

[0010] The pure water outlet is connected to the water inlet, so that the filter element can replenish water to the electronic ice tank when the electronic ice tank is in a cavity state.

[0011] The countertop water purifier also includes a three-way connector, wherein the pure water outlet, the pure water pitcher, and the water replenishment inlet are respectively connected to the three interfaces of the three-way connector, so that the filter element replenishes water to the pure water pitcher through the three-way connector and the pure water pitcher and the filter element replenish water to the electronic ice tank through the three-way connector.

[0012] The tabletop water purifier also includes a water level detection device, which forms a communicating vessel structure with the pure water kettle.

[0013] The water level detection device includes a connecting pipe, a float is installed inside the connecting pipe, and a high water level detector and a low water level detector are installed outside the connecting pipe for detecting the water level by identifying the position of the float. When the low water level detector identifies the position of the float, it controls the cold water pump to cut off the power and controls the filter element to replenish water to the pure water kettle. When the high water level detector identifies the position of the float, it controls the filter element to stop replenishing water to the pure water kettle.

[0014] The tabletop water purifier also includes a water passage component, which has a water passage cavity and a first water outlet, a second water outlet, and a third water outlet respectively connected to the water passage cavity. The pure water outlet is connected to the first water outlet, the pure water kettle is connected to the second water outlet, and the connecting pipe is connected to the third water outlet.

[0015] The tabletop water purifier also includes a hot water pump and an instant heating element. The pure water kettle draws water outward into the instant heating element through the hot water pump. The water passage component is provided with a fourth water inlet that communicates with the water passage cavity, and the hot water pump is connected to the fourth water inlet.

[0016] The countertop water purifier also includes a water outlet, and the hot water outlet of the instant heating element and the cold water pump are both connected to the water outlet.

[0017] Due to the adoption of the above technical solution, the technical effects achieved by this application include at least the following:

[0018] The countertop water purifier provided in this application includes a filter cartridge, a pure water pitcher, an electronic ice tank, and a cold water pump. The pure water outlet of the filter cartridge is connected to the pure water pitcher, which stores the pure water produced by the filter cartridge. The pure water pitcher is connected to the water inlet of the electronic ice tank, allowing the water stored in the pitcher to replenish the electronic ice tank. Therefore, compared to the method of the filter cartridge producing water while simultaneously replenishing the electronic ice tank, the water stored in the pure water pitcher replenishes the electronic ice tank more quickly and is less prone to air ingress, ensuring that the ice tank's ice-making capacity is maximized. Furthermore, when the electronic ice tank is full of water, the cold water pump draws water from the electronic ice tank while the pure water pitcher replenishes it. By controlling the water pump's pumping rate per unit time to match the water replenishment rate from the pure water pitcher, the electronic ice tank can be kept full of water without the need for an additional water level detection structure, thus helping to save on component costs. In addition, since the cold water pump is a two-way non-return pump, once the cold water pump is powered off, it cuts off the internal water flow channel, and the electronic ice tank can no longer dispense water. Even if the water circuit structure upstream of the electronic ice tank exerts water pressure on the electronic ice tank, it will not squeeze the water out of the electronic ice tank. Only when the cold water pump is pumping water will the pure water kettle replenish the electronic ice tank, effectively maintaining the electronic ice tank in a full water state.

[0019] As a preferred embodiment of this application, both the water inlet and the chilled water outlet are located at the top of the electronic chiller, allowing the water pipes connected to the electronic chiller to be centrally arranged above it, optimizing the water circuit structure and facilitating pipe connections. The chilled water outlet exits through a suction pipe. Since the suction pipe is inserted into the electronic chiller and extends towards its bottom, during water replenishment, the denser chilled water concentrates at the bottom, while the newly added, less dense room-temperature water is located at the top. This allows the suction pipe to draw out the chilled water at the bottom, minimizing the removal of the newly added room-temperature water and ensuring the chilled water outlet temperature meets the low-temperature requirements.

[0020] Furthermore, the outer wall of the suction pipe and the inner wall of the ice water outlet form an air intake gap for the cold water pump to draw in the air inside the electronic ice tank. This allows the cold water pump to draw water from the electronic ice tank while simultaneously drawing out the air that has entered the electronic ice tank, ensuring that the electronic ice tank is filled with water without accumulating air. Moreover, this design eliminates the need for separate exhaust ports and exhaust pipes on the electronic ice tank, simplifying its structure.

[0021] As a preferred embodiment of this application, the pure water outlet and the water replenishment inlet are connected, so that in addition to the pure water pitcher replenishing water to the electronic ice tank, the newly produced water from the filter cartridge can also be directly replenished into the electronic ice tank. For example, when the countertop water purifier is used for the first time after leaving the factory, part of the water produced by the filter cartridge can be replenished into the pure water pitcher, and the other part can be replenished into the electronic ice tank.

[0022] Furthermore, by connecting the pure water outlet of the filter cartridge, the pure water pitcher, and the water inlet of the electronic ice tank through a three-way connector, the three-way connector has multiple functions, including introducing the pure water produced by the filter cartridge into the pure water pitcher, introducing the pure water produced by the filter cartridge into the electronic ice tank, and introducing the water stored in the pure water pitcher into the electronic ice tank. This helps to simplify the water circuit structure of the countertop water purifier and improve the integration and compactness of the equipment.

[0023] As a preferred embodiment of this application, the water level detection device and the pure water kettle form a communicating vessel structure, which can intuitively show the water level in the pure water kettle so that water can be added in time when the water level is low and water can be stopped when the water level is high.

[0024] Furthermore, as the water pump operates and continuously replenishes the electronic ice tank with water from the pure water jug, causing the water level to drop continuously, in order to prevent the water in the pure water jug ​​from being drained, the water pump is powered off when the position of the float is detected by the low water level detection device. The water pump stops pumping water and the pure water jug ​​stops discharging water, thus keeping the water level in the pure water jug ​​at a low water level. Attached Figure Description

[0042] 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.

[0043] like Figures 1 to 9 As shown, the countertop water purifier provided in this application includes a filter cartridge 1, a pure water pitcher 2, an electronic ice tank 3, and a cold water pump 4. The pure water outlet of the filter cartridge 1 is connected to the pure water pitcher 2. The cold water pump 4 is connected to the ice water outlet 31 of the electronic ice tank 3. The cold water pump 4 is configured as a bidirectional check pump that cuts off the internal water flow channel when the power is off. The pure water pitcher 2 is connected to the water inlet 32 ​​of the electronic ice tank 3, so that while the cold water pump 4 draws water from the electronic ice tank 3, the pure water pitcher 2 replenishes water to the electronic ice tank 3, thereby maintaining the electronic ice tank 3 in a full water state.

[0044] The countertop water purifier provided in this application includes a filter cartridge 1, a pure water pitcher 2, an electronic ice tank 3, and a cold water pump 4. The filter cartridge 1 is used to filter raw water into pure water. The pure water outlet of the filter cartridge 1 is connected to the pure water pitcher 2, which can store the pure water produced by the filter cartridge 1. The pure water pitcher 2 can also be used to supply water to the water outlet 30 of the countertop water purifier. The pure water pitcher 2 is connected to the water inlet 32 ​​of the electronic ice tank 3, so that the water stored in the pure water pitcher 2 can be used as a water source to replenish the electronic ice tank 3. Therefore, compared with the method of making water from the filter cartridge 1 while replenishing water into the electronic ice tank 3, the water stored in the pure water pitcher 2 replenishes the electronic ice tank 3 faster and is less likely to introduce air, ensuring that the ice water making capacity of the electronic ice tank 3 can be maximized. Furthermore, when the electronic ice tank 3 is full of water, the cold water pump 4 draws water from the electronic ice tank 3 while the pure water jug ​​2 replenishes water to the electronic ice tank 3. By controlling the water flow rate of the cold water pump 4 to match the replenishment rate of the pure water jug ​​2 per unit time, the electronic ice tank 3 can remain fully filled without the need for an additional water level detection structure, thus saving on component costs. Specifically, the water flow rate of the cold water pump 4 can be controlled by adjusting its power, the diameter and length of the water pipe, and other suitable methods. Additionally, since the cold water pump 4 is a bidirectional check pump, once the power to the cold water pump 4 is cut off, the internal water flow channel is interrupted, and the electronic ice tank 3 can no longer dispense water. Even if the upstream water system exerts water pressure on the electronic ice tank 3, it will not force water out of the electronic ice tank 3. The pure water jug ​​2 will only replenish water to the electronic ice tank 3 when the cold water pump 4 is drawing water, effectively maintaining the electronic ice tank 3 as a full water tank.

[0045] As a preferred embodiment of this application, such as Figures 2 to 4 As shown, both the water inlet 32 ​​and the ice water outlet 31 are located at the top of the electronic ice tank 3. The ice water outlet 31 is connected to a suction pipe 5, which is inserted into the electronic ice tank 3 and extends towards the bottom of the electronic ice tank 3. Those skilled in the art will understand that the location of both the water inlet 32 ​​and the ice water outlet 31 at the top of the electronic ice tank 3 allows the water pipe structure connected to the electronic ice tank 3 to be centrally arranged above the electronic ice tank 3, optimizing the water path structure. Water exits through the ice water outlet 31 via the suction pipe 5. Because the suction pipe 5 is inserted into the electronic ice tank 3 and extends towards the bottom of the electronic ice tank 3, during the water replenishment process, the denser ice water concentrates at the bottom of the electronic ice tank 3, while the newly added, less dense room-temperature water is located at the top of the electronic ice tank 3. Therefore, the suction pipe 5 can extract the ice water at the bottom, minimizing the extraction of the newly added room-temperature water from above, ensuring that the ice water outlet temperature meets the low-temperature requirements.

[0046] Furthermore, such as Figure 4As shown, the outer wall of the suction pipe 5 and the inner wall of the ice water outlet 31 form an air intake gap 6 for the cold water pump 4 to draw gas from the electronic ice tank 3. This allows the cold water pump 4 to draw water from the electronic ice tank 3 while simultaneously drawing out the air that has entered the electronic ice tank 3, ensuring that the electronic ice tank 3 is filled with water without accumulating air. Moreover, this design eliminates the need for a separate exhaust port or exhaust pipe on the electronic ice tank 3, simplifying its structure. In a preferred embodiment, the suction pipe 5 can have multiple outwardly protruding protrusions. These protrusions connect to the inner wall of the ice water outlet 31, fixing the suction pipe 5 in place, while adjacent protrusions form the air intake gap 6 for the cold water pump 4 to draw gas. Specifically, when the tabletop water purifier is used for the first time after leaving the factory, there will inevitably be a lot of air in the electronic ice tank 3. Therefore, after the cold water pump 4 removes all the air through the air intake gap 6, the water can be used to fill the electronic ice tank 3 with water, so that after the cold water pump 4 stops pumping water, the electronic ice tank 3 remains full of water.

[0047] In a preferred embodiment of this application, the pure water outlet is connected to the water inlet 32, allowing the filter cartridge 1 to replenish water to the electronic ice tank 3 when the electronic ice tank 3 is in an empty state. This design allows not only the pure water pitcher 2 to replenish water to the electronic ice tank 3, but also the newly produced water from the filter cartridge 1 to be directly added to the electronic ice tank 3. For example, when the countertop water purifier is used for the first time after leaving the factory, part of the water produced by the filter cartridge 1 can be added to the pure water pitcher 2, and the other part to the electronic ice tank 3. However, because the electronic ice tank 3 contains a large amount of air during the first use, as the water level rises, this air is compressed, increasing the pressure inside the electronic ice tank 3. This prevents the water produced by the filter cartridge 1 from filling the electronic ice tank 3 completely. Only after the cold water pump 4 removes the air can the pure water pitcher 2 fill the electronic ice tank 3 with water.

[0048] In a preferred embodiment, such as Figure 5 , Figure 6 and Figure 7As shown, the countertop water purifier also includes a three-way connector 7. The pure water outlet, the pure water pitcher 2, and the water inlet 32 ​​are respectively connected to the three ports of the three-way connector 7, allowing the filter cartridge 1 to replenish water to the pure water pitcher 2 through the three-way connector 7, and allowing the pure water pitcher 2 and the filter cartridge 1 to replenish water to the electronic ice tank 3 through the three-way connector 7. Those skilled in the art will understand that by connecting the pure water outlet of the filter cartridge 1, the pure water pitcher 2, and the water inlet 32 ​​of the electronic ice tank 3 through the three-way connector 7, the three-way connector 7 has multiple functions, including introducing the pure water produced by the filter cartridge 1 into the pure water pitcher 2, introducing the pure water produced by the filter cartridge 1 into the electronic ice tank 3, and introducing the water stored in the pure water pitcher 2 into the electronic ice tank 3. This helps simplify the water circuit structure of the countertop water purifier and improves its integration and compactness. Moreover, the water inlet of the pure water pitcher 2, which connects to the three-way connector 7, is not only a water inlet for inlet water but also an outlet for outlet water to the electronic ice tank 3.

[0049] As a preferred embodiment of this application, the tabletop water purifier further includes a water level detection device. The water level detection device and the pure water kettle 2 form a communicating vessel structure, which can intuitively show the water level in the pure water kettle 2 so that water can be added in time when the water level is low and water can be stopped when the water level is high.

[0050] Regarding the structure of the water level detection device, in a preferred embodiment, such as Figure 2 and Figure 8As shown, the water level detection device includes a connecting pipe 81, a float 82 inside the connecting pipe 81, and a high water level identifier 83 and a low water level identifier 84 outside the connecting pipe 81 for detecting the water level by identifying the position of the float 82. When the low water level identifier 84 detects the position of the float 82, it controls the cold water pump 4 to cut off the power and controls the filter element 1 to replenish water to the pure water kettle 2. When the high water level identifier 83 detects the position of the float 82, it controls the filter element 1 to stop replenishing water to the pure water kettle 2. Specifically, the high water level identifier 83 and the low water level identifier 84 can be connected to a circuit board with a reed switch and a resistor inside. The magnetic float 82 activates the reed switch to detect the water level. As the cold water pump 4 operates, water continuously flows into the electronic ice tank 3, causing the water level in the pure water jug ​​2 to drop. To prevent the pure water jug ​​2 from drying out, the cold water pump 4 is de-energized when the low water level detection component 84 identifies the position of the float 82. The cold water pump 4 stops pumping water, and the pure water jug ​​2 stops discharging water, thus keeping the water level in the pure water jug ​​2 at a low level. When the filter cartridge 1 replenishes water to the pure water jug ​​2, the high water level detection component 83 identifies the position of the float 82 and controls the filter cartridge 1 to stop replenishing water to the pure water jug ​​2, thus keeping the water level in the pure water jug ​​2 at a high level. In other embodiments, the water level detection device can also be equipped with other water level detection structures besides high and low water levels, such as a water level detection structure for detecting the intermediate water level between high and low water levels.

[0051] Furthermore, such as Figure 2 as well as Figures 5 to 9 As shown, the countertop water purifier also includes a water-passing component 9. The water-passing component 9 has a water-passing chamber and a first water inlet 91, a second water inlet 92, and a third water inlet 93 respectively connected to the water-passing chamber. The pure water outlet is connected to the first water inlet 91, the pure water pitcher 2 is connected to the second water inlet 92, and the connecting pipe 81 is connected to the third water inlet 93. The water-passing component 9 integrates multiple functions, including connecting the filter element 1 to the pure water pitcher 2 and connecting the filter element 1 to the connecting pipe 81. The pure water produced by the filter element 1 can simultaneously enter the pure water pitcher 2 and the connecting pipe 81 through the water-passing component 9, ensuring that the pure water pitcher 2 and the connecting pipe 81 achieve water level detection through the communicating vessel principle.

[0052] Furthermore, such as Figure 5 and Figure 6As shown, the countertop water purifier also includes a hot water pump 10 and an instant heating element 20. The pure water kettle 2 draws water from the hot water pump 10 into the instant heating element 20. The water passage component 9 is provided with a fourth water inlet 94 communicating with the water passage cavity, and the hot water pump 10 is connected to the fourth water inlet 94. The water passage component 9 integrates multiple functions. In addition to connecting the filter element 1 to the pure water kettle 2 and the connecting pipe 81 respectively, it also connects the pure water kettle 2 to the instant heating element 20, so that the hot water pump 10 draws water from the pure water kettle 2 into the instant heating element 20 for heating, enabling the countertop water purifier to provide hot water in a short time.

[0053] Furthermore, such as Figure 5 and Figure 7 As shown, the countertop water purifier also includes a water outlet 30. The hot water outlet of the instant heating element 20 and the cold water pump 4 are both connected to the water outlet 30, so that the hot water from the instant heating element 20 and the ice water from the electronic ice tank 3 are discharged through the same water outlet 30.
