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. This has led to increasing recognition and favor for countertop water purifiers. Compared to floor-standing water purifiers, countertop water purifiers are smaller in size, take up less space, and can be placed directly on a countertop, making them convenient to use.

[0003] Compared to traditional water dispensers, countertop water purifiers offer the added function of filtering raw water into purified water. Some countertop models also include a purified water pitcher for storage, with a base on the machine for holding the pitcher. The pitcher can be easily moved from the base, essentially functioning as a portable cup, enhancing convenience. The purified water stored in the pitcher can be directly supplied to the tap or heated to boiling water using an instant heating element. Specifically, to facilitate water intake and dispensing from the pitcher, a water inlet is typically located at the bottom of the pitcher. The base has a coupling device that connects to the water inlet, and this coupling device contains a water passage chamber that connects to the water inlet at the bottom of the pitcher. The purified water inside the pitcher is then conveyed outwards through this coupling device. To facilitate monitoring of the water level in the purified water jug, some countertop water purifiers use a water level connector that connects to the bottom spout of the jug to monitor the water level. This connector is typically connected to a coupling. However, this design has certain drawbacks. For example, when the countertop water purifier draws water from the jug, the water level in the connector and the jug may change at different rates, interfering with normal operation. Countertop water purifiers generally use a pump to draw water from the jug, but the uneven distribution of the strong suction generated by the pump can cause the water level in the connector and the jug to drop at different rates. Especially when most of the strong suction acts on the end connected to the connector, the water level in the connector will drop faster than the water level in the jug, increasing the risk of the jug stopping dispensing water prematurely. Utility Model Content

[0004] This application provides a countertop water purifier to improve or solve the technical problem in existing countertop water purifiers where the water level in the communicating vessel changes at a different rate than the water level in the pure water kettle.

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

[0006] A countertop water purifier includes a body and a pure water kettle. The body has a kettle stand for placing the pure water kettle. The bottom of the pure water kettle has a bottom water outlet. The kettle stand has a coupling component for coupling and connecting with the bottom water outlet. The countertop water purifier also includes a water level connector for detecting the water level in the pure water kettle and a water pump for drawing water from the pure water kettle. The coupling component includes a coupling seat with a water passage cavity. The water passage cavity has a first water outlet and a second water outlet. The water level connector is connected to the first water outlet, and the water pump is connected to the second water outlet. The water passage cavity has a water-blocking rib, and the first water outlet and the second water outlet are distributed on both sides of the water-blocking rib.

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

[0008] The water passage cavity includes an upper cavity and a lower cavity. The cross-sectional area of ​​the upper cavity is larger than that of the lower cavity. The first water inlet and the second water inlet are located in the lower cavity.

[0009] The water-blocking rib divides the lower cavity into a first water passage area and a second water passage area. The volume of the first water passage area is smaller than the volume of the second water passage area. The first water outlet is located in the first water passage area, and the second water outlet is located in the second water passage area.

[0010] The opening position of the first water inlet is not higher than the opening position of the second water inlet in the vertical direction.

[0011] The coupling seat is provided with an outwardly extending first guide pipe, the first water inlet is formed in the first guide pipe, the first guide pipe is provided with a guide component, the guide component is provided with a Tesla valve channel, and the water passage cavity is connected to the water level connector in the forward direction through the Tesla valve channel.

[0012] The countertop water purifier also includes a filter cartridge capable of supplying water to the pure water pitcher, and the purified water outlet of the filter cartridge is connected to the second water inlet.

[0013] The coupling seat is provided with a second guide pipe extending outward, and the second water outlet is formed in the second guide pipe. The tabletop water purifier also includes a three-way connector. The purified water outlet of the filter element is connected to the first interface of the three-way connector, and the second and third interfaces of the three-way connector are respectively connected to the water pump and the second guide pipe.

[0014] The coupling component also includes a coupling cover that fits onto the top of the coupling seat. The coupling cover has a water passage for connecting the water passage cavity and the water outlet at the bottom of the kettle. A first valve body that can move up and down is installed in the water passage, and a second valve body that can move up and down is installed in the water outlet at the bottom of the kettle. The pure water kettle is placed on the kettle seat, causing the first valve body to move downward to open the water passage, and causing the second valve body to move upward to open the water outlet at the bottom of the kettle.

[0015] The bottom of the pure water kettle is provided with a lower top protrusion surrounding the bottom water outlet, and the water passage is provided with an upper top protrusion. The pure water kettle is placed on the kettle seat, so that the upper top protrusion pushes the second valve body to move upward to open the bottom water outlet, and the lower top protrusion pushes the first valve body to move downward to open the water passage.

[0016] The kettle base is provided with an allowance slot for the lower top protrusion to be inserted into the water passage and a limiting rib surrounding the allowance slot. The limiting rib is provided with an elastic sealing ring. The lower top protrusion is arranged around the water outlet at the bottom of the kettle. The elastic sealing ring forms a seal between the lower top protrusion and the coupling cover.

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

[0018] 1. The countertop water purifier provided in this application has a first water inlet of the coupling seat connected to a water level connector, which connects the water level connector to the pure water kettle, enabling the water level connector to monitor the water level in the pure water kettle. The second water inlet of the coupling seat is connected to a water pump, allowing the water pump to draw water from the pure water kettle through the coupling. By providing a water-blocking rib in the water passage cavity, the first and second water inlets are distributed on both sides of the water-blocking rib and are thus separated by the water-blocking rib. Under the blocking effect of the water-blocking rib on the second water inlet, the suction force generated by the water pump when drawing water is prevented from directly acting on the first water inlet and directly drawing water from the water level connector, thereby improving the problem that the water level in the water level connector drops too quickly compared to the water level in the pure water kettle.

[0019] 2. As a preferred embodiment, the water passage cavity includes an upper cavity and a lower cavity, forming a segmented design. The cross-sectional area of ​​the upper cavity is larger than that of the lower cavity, increasing the water storage capacity of the upper cavity. The first and second water inlets are located in the lower cavity. When the water pump is pumping water, the water in the lower and upper cavities gradually replenishes the second water inlet, effectively preventing the suction force of the water pump from directly acting on the first water inlet. Moreover, during the pumping process, the water in the water level connector and the water in the pure water kettle will merge together in the upper cavity before flowing towards the second water inlet, further preventing the water level connector from discharging water too quickly. The water discharging speeds of the water level connector and the pure water kettle tend to be balanced, and the water level change rates of the two are basically the same.

[0020] 3. As a preferred method, the water-blocking rib divides the lower cavity into a first water-passing zone and a second water-passing zone. The volume of the first water-passing zone is smaller than that of the second water-passing zone. The first water inlet is located in the first water-passing zone, and the second water inlet is located in the second water-passing zone. This makes the water storage capacity in the second water-passing zone greater than that in the first water-passing zone. The suction force of the water pump acts directly on the second water-passing zone. The larger water storage capacity in the second water-passing zone makes it easier to meet the water pumping demand, thereby reducing the impact of suction force on the first water-passing zone and the first water inlet located in the first water-passing zone, and further preventing the water level inside the water level connector from dropping too quickly.

[0021] 4. As a preferred method, the opening position of the first water inlet is not higher than the opening position of the second water inlet in the vertical direction. This ensures that when the water pump is pumping water, the direction of water flow from the first water inlet to the second water inlet is opposite to the direction of water flow from the water passage chamber to the second water inlet. Therefore, the water in the first water inlet is blocked from flowing upward, which greatly reduces the risk of the water pump directly and quickly pumping water from the first water inlet and avoids the water level in the water level connector from dropping too quickly compared to the water level in the pure water kettle.

[0022] 5. As a preferred embodiment, the first guide pipe is equipped with a guide component, which has a Tesla valve channel. The water passage chamber is connected to the water level connector in the forward direction through the Tesla valve channel. This allows the water to flow forward in the Tesla valve channel when the countertop water purifier adds water to the pure water pitcher and the water level connector, with minimal obstruction. However, when the water pump draws water from the pure water pitcher, the water flows backward in the water passage chamber through the Tesla valve channel from the water level connector. The resistance of the Tesla valve channel prevents the water level in the water level connector from dropping too quickly compared to the water level in the pure water pitcher.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0050] 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. It should be noted that, for ease of understanding, the accompanying drawings only schematically illustrate the core structures of the countertop water purifier that are directly or indirectly related to this solution, and other structures are omitted.

[0051] like Figures 1 to 10As shown, the tabletop water purifier provided in this application includes a body 1 and a pure water kettle 2. The body 1 is provided with a kettle seat 11 for placing the pure water kettle 2. The bottom of the pure water kettle 2 is provided with a bottom water outlet 21. The kettle seat 11 is provided with a coupling member 3 for coupling and docking with the bottom water outlet 21. The tabletop water purifier also includes a water level connector 4 for detecting the water level in the pure water kettle 2 and a water pump (not shown in the figure) for drawing water from the pure water kettle 2. The coupling member 3 includes a coupling seat 31. The coupling seat 31 is provided with a water passage cavity 311. The water passage cavity 311 is provided with a first water outlet 312 and a second water outlet 313. The water level connector 4 is connected to the first water outlet 312. The water pump is connected to the second water outlet 313. The water passage cavity 311 is provided with a water-blocking rib 314. The first water outlet 312 and the second water outlet 313 are distributed on both sides of the water-blocking rib 314.

[0052] The countertop water purifier of this application includes a pure water pitcher 2 for storing filtered pure water and discharging it. A coupling 3 serves as the inlet and outlet for the pure water pitcher 2, integrating a water level connector 4, the pure water pitcher 2, and a water pump. The first inlet 312 of the coupling 31 connects to the water level connector 4, enabling communication between the connector and the pitcher, thus allowing the connector to monitor the water level within the pitcher. The second inlet 313 of the coupling 31 connects to the water pump, allowing the pump to operate via the coupling. Component 3 draws water from the pure water kettle 2; by providing a water-blocking rib 314 in the water passage cavity 311, the first water inlet 312 and the second water inlet 313 are distributed on both sides of the water-blocking rib 314 and are thus separated by the water-blocking rib 314. Under the blocking effect of the water-blocking rib 314 on the second water inlet 313, the suction force generated by the water pump when drawing water is prevented from directly acting on the first water inlet 312 and directly and quickly drawing water from the water level connector 4, thereby improving the problem that the water level in the water level connector 4 drops too quickly compared to the water level in the pure water kettle 2.

[0053] As a preferred embodiment of this application, such as Figure 3 , Figure 4 and Figure 5As shown, the water passage cavity 311 includes an upper cavity 3111 and a lower cavity 3112. The cross-sectional area of ​​the upper cavity 3111 is larger than the cross-sectional area of ​​the lower cavity 3112. The first water inlet 312 and the second water inlet 313 are located in the lower cavity 3112. Those skilled in the art will understand that the water passage 311 includes an upper cavity 3111 and a lower cavity 3112, forming a segmented design. The cross-sectional area of ​​the upper cavity 3111 is larger than that of the lower cavity 3112, increasing the water storage capacity in the upper cavity 3111. The first water inlet 312 and the second water inlet 313 are located in the lower cavity 3112. When the water pump is pumping water, the water in the lower cavity 3112 and the upper cavity 3111 is gradually replenished into the second water inlet 313, effectively preventing the suction force of the water pump from directly acting on the first water inlet 312. Moreover, during the process of the water pump pumping water, the water in the water level connector 4 and the water in the pure water bottle 2 will merge together in the upper cavity 3111 before flowing towards the second water inlet 313, further preventing the water level connector 4 from discharging water too quickly. The water level connector 4 and the pure water bottle 2 tend to be balanced, and their water level change rates are basically the same.

[0054] Furthermore, such as Figures 3 to 7 As shown, the water-blocking rib 314 divides the lower cavity 3112 into a first water passage area 31121 and a second water passage area 31122. The volume of the first water passage area 31121 is smaller than the volume of the second water passage area 31122. The first water inlet 312 is located in the first water passage area 31121, and the second water inlet 313 is located in the second water passage area 31122. Those skilled in the art will understand that, typically, after the water pump stops pumping, some undischarged water remains in the water passage chamber 311. This water is mainly stored in the lower chamber 3112. Therefore, by making the volume of the first water passage zone 31121 smaller than the volume of the second water passage zone 31122, the water storage capacity in the second water passage zone 31122 is greater than that in the first water passage zone 31121. The suction force of the water pump acts directly on the second water passage zone 31122. The larger water storage capacity in the second water passage zone 31122 makes it easier to meet the pumping demand of the water pump, thereby reducing the impact of suction force on the first water passage zone 31121 and the first water outlet 312 located in the first water passage zone 31121, and further preventing the water level inside the water level connector 4 from dropping too quickly.

[0055] In a preferred embodiment, the opening position of the first sprue 312 is not higher than the opening position of the second sprue 313 in the vertical direction. Figure 4 and Figure 7The diagram illustrates a configuration where the first water inlet 312 and the second water inlet 313 are at the same vertical height. Alternatively, the first water inlet 312 could be positioned lower than the second water inlet 313. Those skilled in the art will understand that when the water pump draws water, the water flowing into the water passage 311 flows from top to bottom towards the second water inlet 313. By ensuring that the opening of the first water inlet 312 is not higher than the opening of the second water inlet 313 vertically, if the water flowing from the first water inlet 312 towards the second water inlet 313, it must flow from bottom to top and over the baffle 314. This is opposite to the direction of water flow from the water passage 311 towards the second water inlet 313, thus blocking the upward flow. Therefore, the risk of the water pump rapidly drawing water directly from the first water inlet 312 is greatly reduced, preventing the water level in the water level connector 4 from dropping too quickly compared to the water level in the pure water kettle 2.

[0056] As a preferred embodiment of this application, such as Figure 3 , Figure 6 and Figure 7 As shown, the coupling seat 31 is provided with an outwardly extending first guide pipe 315, the first water inlet 312 is formed inside the first guide pipe 315, the first guide pipe 315 is provided with a guide member 5, the guide member 5 is provided with a Tesla valve channel 51, and the water passage 311 is forwardly connected to the water level connector 4 through the Tesla valve channel 51. Those skilled in the art will understand that, because the water passage 311 is forwardly connected to the water level connector 4 through the Tesla valve channel 51, when the countertop water purifier adds water to the pure water jug ​​2 and the water level connector 4, the water flows forward within the Tesla valve channel 51 with minimal resistance. However, when the water pump draws water from the pure water jug ​​2, the water flows backward through the Tesla valve channel 51 from the water level connector 4 to the water passage 311. Under the resistance of the Tesla valve channel 51, the water level in the water level connector 4 is prevented from dropping too quickly compared to the water level in the pure water jug ​​2.

[0057] In a preferred embodiment of this application, the countertop water purifier further includes a filter cartridge (not shown in the drawings) capable of supplying water to the pure water pitcher 2, with the purified water outlet of the filter cartridge connected to the second water inlet 313. Those skilled in the art will understand that when the water level in the pure water pitcher 2 is too low, water needs to be added. Therefore, by connecting the purified water outlet of the filter cartridge to the second water inlet 313, the purified water filtered by the filter cartridge is replenished into the pure water pitcher 2 through the coupling member 3. This allows the coupling member 3 to integrate multiple functions, including water replenishment, water dispensing, and connecting the pure water pitcher 2 to the water level connector 4. This integration of functions simplifies the structure of the countertop water purifier and reduces the failure rate.

[0058] Furthermore, such as Figure 2 and Figure 3As shown, the coupling seat 31 is provided with an outwardly extending second guide pipe 316, and the second water inlet 313 is formed inside the second guide pipe 316. The countertop water purifier also includes a three-way connector 7. The purified water outlet of the filter element is connected to the first interface of the three-way connector 7, and the second and third interfaces of the three-way connector 7 are respectively connected to the water pump and the second guide pipe 316. In addition, to facilitate the connection between the filter element and the three-way connector 7, the countertop water purifier can also include a two-way connector 6. One interface of the two-way connector 6 is connected to the purified water outlet of the filter element, and the other interface of the two-way connector 6 is connected to the first interface of the three-way connector 7. The filter element, coupling element 3, and water pump are connected through the cooperation of the two-way connector 6 and the three-way connector 7, so that the filter element replenishes water to the pure water jug ​​2 through the two-way connector 6 and the three-way connector 7, and the water pump draws water from the pure water jug ​​2 through the three-way connector 7.

[0059] As a preferred embodiment of this application, such as Figure 1 , Figure 8 , Figure 9 and Figure 10 As shown, the coupling member 3 also includes a coupling cover 32 that fits onto the top of the coupling seat 31. The coupling cover 32 has a water passage 321 for connecting the water passage cavity 311 and the water outlet 21 at the bottom of the kettle. A first valve body 8 that can move up and down is installed in the water passage 321, and a second valve body 9 that can move up and down is installed in the water outlet 21 at the bottom of the kettle. Figure 8 The diagram shows the purified water jug ​​2 placed on the jug base 11. At this position, the first valve body 8 moves downwards to open the water passage 321, and the second valve body 9 moves upwards to open the bottom water inlet 21. The bottom water inlet 21 connects to the water cavity 311 through the water passage 321. Furthermore, springs can be installed between the first valve body 8 and the coupling seat 31, and also between the second valve body 9 and the purified water jug ​​2. When the purified water jug ​​2 is removed from the jug base 11, the two springs respectively drive the first valve body 8 and the second valve body 9 to reset, thereby closing the bottom water inlet 21 and the water passage 321 to prevent leakage. The coupling seat 31 and the coupling cover 32 are separate designs. During assembly, the spring can be pre-installed in the coupling seat 31, and then the coupling cover 32 can be installed. Regarding the fitting method of the coupling seat 31 and the coupling cover 32, in a preferred embodiment, they can be threaded together or fitted with a screw thread and a groove. Alternatively, they can be welded together.

[0060] Regarding the method of placing the pure water kettle 2 on the kettle base 11 to achieve the downward movement of the first valve body 8 and the upward movement of the second valve body 9, in a specific embodiment, the first valve body 8 and the second valve body 9 can be made to contact and abut against each other, so that the first valve body 8 pushes the second valve body 9 upward, and the second valve body 9 pushes the first valve body 8 downward. In a preferred embodiment, such as... Figure 9 and Figure 10As shown, the bottom of the pure water kettle 2 is provided with a lower top protrusion 22 surrounding the bottom water inlet 21, and the water passage 321 is provided with an upper top protrusion 322. The pure water kettle 2 is placed on the kettle base 11, so that the upper top protrusion 322 pushes the second valve body 9 upward to open the bottom water inlet 21, and the lower top protrusion 22 pushes the first valve body 8 downward to open the water passage 321. The independently designed upper top protrusion 322 and lower top protrusion 22 have simple structures and occupy little space, which helps to simplify the structure of the first valve body 8 and the second valve body 9, and thus helps to miniaturize the design of the pure water kettle 2 and the kettle base 11. Moreover, the pushing stroke of the upper top protrusion 322 on the second valve body 9 and the pushing stroke of the lower top protrusion 22 on the first valve body 8 are both rigid structure strong pushing strokes, which improves the reliability of operation.

[0061] Furthermore, such as Figure 9 and Figure 10 As shown, the kettle base 11 is provided with an avoidance socket 111 for the lower top protrusion 22 to be inserted into the water passage 321 and a limiting rib 112 surrounding the avoidance socket 111. An elastic sealing ring 10 is provided in the limiting rib 112. The lower top protrusion 22 is arranged around the water outlet 21 at the bottom of the kettle. The elastic sealing ring 10 forms a seal between the lower top protrusion 22 and the coupling cover 32. Those skilled in the art will understand that by forming a seal between the elastic sealing ring 10 and the coupling cover 32, on the one hand, when the pure water bottle 2 is placed on the bottle holder 11, the elastic sealing ring 10 can prevent water from leaking outward through the mating gap between the lower top protrusion 22 and the coupling cover 32; on the other hand, during the process of removing the pure water bottle 2 from the bottle holder 11, the lower top protrusion 22 slides upward along the elastic sealing ring 10. During this sliding process, the elastic sealing ring 10 can still tightly adhere to the lower top protrusion 22 and continue to provide a sealing effect. When the lower top protrusion 22 disengages from the elastic sealing ring 10, the first valve body 8 and the second valve body 9 have respectively sealed the water passage 321 and the bottom water outlet 21 of the bottle, thereby preventing water leakage. The elastic sealing ring 10 is confined within the limiting rib 112, ensuring reliable installation and also helping to improve the sealing effect. Specifically, the elastic sealing ring 10 can also be fastened to the top of the coupling cover 32 to further improve the installation reliability and sealing effect.
