Description

Technical Field

[0001] This utility model relates to the field of water purifiers, and in particular to a water tank and a countertop water purifier. Background Technology

[0002] As people's living standards continue to improve, their awareness of drinking water safety also increases, leading to the increasing popularity of water purifiers. While under-sink water purifiers are very common, countertop water purifiers (those placed on office desks or dining tables) are relatively less prevalent. A countertop water purifier typically includes a water tank, a filtration system, a water circuit board, and the main body. The water circuit board is installed on the main body and connected to the bottom of the water tank. The water tank contains raw water and has a first outlet and a first wastewater outlet. The water circuit board has a second outlet and a second wastewater outlet corresponding to the first outlet and wastewater outlet. Raw water from the tank flows from the first outlet through the second outlet into the filtration system. The purified water after filtration is left for use, while wastewater from the filtration system flows from the second wastewater outlet through the first wastewater outlet back into the water tank.

[0003] For countertop water purifiers, the water tank's sealing performance and the filtration system's lifespan are crucial performance indicators. However, current technology often suffers from suboptimal water tank sealing, and the tank's structural design can negatively impact the filtration system's lifespan. Furthermore, the water in the countertop water purifier's tank is prone to microbial contamination, leading to the growth of algae and other microorganisms, thus compromising water quality safety. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects in the existing technology where the structural design of the water tank easily affects the service life of the filtration system of the countertop water purifier and easily affects water quality safety, and to provide a water tank and a countertop water purifier.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A water tank for a countertop water purifier, the water tank comprising a tank body, the bottom of the tank body being provided with:

[0007] The first water outlet is connected to the interior of the water tank so that the raw water stored in the water tank can flow out from the first water outlet;

[0008] The first wastewater outlet is connected to the interior of the water tank so that the wastewater formed after the raw water is filtered can flow into the water tank from the first wastewater outlet.

[0009] The water tank also includes a protective element disposed inside the tank body. The protective element is a hollow columnar structure. The first end of the protective element along the axial direction is disposed at the first water outlet, and the second end extends in a direction away from the first water outlet.

[0010] Wherein, along the flow direction of the raw water, the water flow is configured to flow sequentially through the second end, the first end and the first outlet of the protective element;

[0011] The water tank also includes a sterilization component, which is installed on the tank body. The sterilization component has an electrical connection end and a sterilization end. The sterilization end is located inside the tank body, and the electrical connection end extends to the outside of the tank body and is sealed to the tank body.

[0012] In this design, raw water flows out of the tank body through the first outlet, while wastewater flows in through the first wastewater outlet. The wastewater gradually mixes with the raw water. A protective element at the first outlet ensures that water only flows into the filtration system through the protective element and the first outlet when the raw water level in the tank exceeds the height of the protective element. Therefore, the protective element limits water flow into the filtration system when the water level is low. The tank supplies water to the reverse osmosis system. As the water level in the raw water tank decreases, the concentration of the raw water and wastewater mixture increases, leading to a higher system recovery rate. A lower recovery rate better protects the reverse osmosis membrane, thus extending or ensuring the lifespan of the filtration system. In other words, by setting a protective element, the water level flowing into the filtration system is limited to a preset range, thereby ensuring the system recovery rate remains within a preset range and protecting the reverse osmosis membrane, thus extending or ensuring the lifespan of the filtration system. Furthermore, the sterilization component promptly sterilizes the water inside the tank, contributing to water quality safety.

[0013] Preferably, the sterilization component is arranged laterally relative to the box body;

[0014] And / or, along the height direction of the box body, the sterilization component is located above the protective element.

[0015] In this design, the sterilization component is positioned horizontally. This reduces the space occupied by the sterilization component along the height of the tank body and avoids impacting the top structure of the water tank, while also facilitating operation. Furthermore, positioning the sterilization component above the protective element prevents interference between them, ensuring the normal operation of the water tank.

[0016] Preferably, the outer wall surface of the box body is provided with a mounting hole and a first mounting part, and the mounting part extends outward from the position on the outer wall surface of the box body corresponding to the mounting hole;

[0017] The electrical connection end has a second mounting portion, and the sterilization end extends into the mounting hole and is disposed inside the box body. Along the extension direction of the sterilization component, one end of the second mounting portion corresponding to the first mounting portion is provided with an external thread for threaded connection with the first mounting portion.

[0018] In this design, the aforementioned structural configuration allows the sterilization component to be easily and reliably connected to the tank body via the first and second mounting parts, simplifying the overall structure of the water tank. Furthermore, the first mounting part provides support for the sterilization component, ensuring its reliable installation on the tank body.

[0019] Preferably, along the extending direction of the sterilization component, the end of the second mounting portion away from the first mounting portion has an external hexagonal structure.

[0020] In this design, the end of the second mounting section furthest from the first mounting section (i.e., the end exposed outside the box body) is designed as an external hexagonal structure, which makes it easier to install and remove the sterilization components.

[0021] Preferably, the second end of the protective element has a notch.

[0022] In this solution, based on the preset water level, the main function of the notch is to allow water to flow in more easily when the water level inside the tank is relatively low. Therefore, even if the water tank is not necessarily flat in the installation scenario and there is a positional deviation, reliable water flow can still be achieved.

[0023] Preferably, the first water outlet and the first wastewater outlet are spaced apart in the horizontal direction, and the notch is located on the side of the protective element opposite to the first wastewater outlet.

[0024] In this design, the notch faces the opposite direction to the first wastewater outlet. Its main purpose is to prevent excessive wastewater from flowing into the first outlet, allowing the wastewater to settle and settle in the tank before entering the first outlet, thus ensuring the lowest possible level of pollutants in the raw water.

[0025] Preferably, the height of the protective element along the axial direction is adjustable;

[0026] And / or, the water tank further includes a filter element disposed within the protective element, wherein, along the direction of the original water flow, the water flow is configured to flow sequentially through the second end of the protective element, the filter element, the first end, and the first outlet.

[0027] In this solution, as mentioned earlier, by setting up a protective element, the water level flowing into the filtration system can be limited within a preset range, thereby ensuring the system recovery rate remains within a preset range. Therefore, the height of the protective element can control, adjust, or influence the overall recovery rate of the filtration system. Thus, setting the height of the protective element to be adjustable allows it to match filtration systems with different recovery rates and to adapt to water tanks of different sizes, providing a wide range of applicability. Furthermore, the filter element can intercept impurities in the water, primarily granular carbon or other debris from the water purifier's wastewater, preventing them from re-entering the system and further protecting the filtration system.

[0028] Preferably, both the first water outlet and the first wastewater outlet are equipped with waterproof components, which can switch between a first working state and a second working state.

[0029] When the waterproof component is in the first working state, the first water outlet or the first wastewater outlet on which the waterproof component is installed is in the open state.

[0030] When the waterproof component is in the second working state, the first water outlet or the first wastewater outlet on which the waterproof component is installed is in a closed state.

[0031] In this solution, the above-mentioned structural configuration allows the waterproof component to switch between a first working state and a second working state according to actual usage. For example, when the water tank is installed on the water circuit board, the waterproof component switches to the first working state, at which point the water circuit is open, and the solenoid valve inside the water purifier can supply or drain water to the system simply by opening this water circuit. When the water tank is removed from the water circuit board, the waterproof component switches to the second working state, at which point the water in the tank cannot flow out, thus preventing unwanted leakage from the water tank.

[0032] Preferably, the waterproof component includes a sealing frame, a spring, and a sealing gasket, with both ends of the spring supported between the sealing gasket and the sealing frame;

[0033] The sealing frame is installed inside the corresponding first water outlet or first wastewater outlet;

[0034] When the waterproof component is in the first working state, the sealing gasket is separated from the sealing skeleton and supported above the sealing skeleton to form a flow channel. One end of the flow channel is connected to the corresponding first water outlet or first wastewater outlet, and the other end is connected to the interior of the tank body.

[0035] When the waterproof component is in the second working state, the sealing gasket fits against the sealing skeleton to restrict the interior of the tank body from communicating with the corresponding first water outlet or first wastewater outlet.

[0036] In this design, the aforementioned structural configuration simplifies the waterproof component's structure. Adjusting the position of the sealing gasket and sealing frame reliably regulates the component's operating state, simplifying the overall water tank structure and ensuring its sealing performance. When the water tank is installed on the water circuit board, the spring releases the sealing gasket, switching the waterproof component to its first operating state. In this state, the water circuit is open, allowing the solenoid valve inside the water purifier to supply or drain water to the system simply by opening this circuit. When the water tank is removed from the water circuit board, the sealing frame falls, and the spring moves downwards, firmly pressing the sealing gasket against the sealing frame. The waterproof component switches to its second operating state, preventing water from flowing out of the tank and thus preventing unwanted leakage.

[0037] Preferably, the tank body is further provided with a heat exchanger inlet and a heat exchanger outlet, both of which can be opened and closed; wherein, the heat exchanger inlet is used to connect the interior of the tank body with the inlet of the external heat exchanger, and the heat exchanger outlet is used to connect the outlet of the external heat exchanger with the interior of the tank body.

[0038] And / or, the water tank further includes a top cover, which is detachably mounted on the top of the tank body, and the top cover is provided with a vent hole communicating with the interior of the tank body.

[0039] In this design, the aforementioned structure is used, with the tank body additionally equipped with an openable and closable heat exchanger inlet and outlet. Depending on actual requirements, the water tank can be connected to an external heat exchanger, thereby expanding its applicability and meeting diverse usage needs. Furthermore, the vent ensures that the internal pressure of the water tank matches the external pressure, preventing the tank from expanding and rupturing during operation or being damaged by negative pressure.

[0040] Preferably, the top cover has a front end and a rear end in the horizontal direction, the front end and the rear end of the top cover have different cross-sectional dimensions, and a protrusion is provided on the front end or the rear end of the top cover, and a corresponding recess is provided on the box body to cooperate with the protrusion.

[0041] In this design, the aforementioned structural arrangement, with different cross-sectional dimensions at both ends of the top cover, facilitates quick differentiation between the two ends, preventing reverse installation and thus enabling rapid assembly of the top cover and the box body. Furthermore, the protrusions and recesses not only aid in positioning the top cover and box body during installation but also prevent incorrect installation, further ensuring that reverse installation does not occur.

[0042] This utility model also provides a countertop water purifier, including a filtration system. The countertop water purifier also includes the aforementioned water tank. The first water outlet is connected to the inlet of the filtration system, and the first wastewater outlet is connected to the wastewater outlet of the filtration system.

[0043] In this solution, as mentioned above, the structural design of the water tank can improve or guarantee the service life of the filtration system. Therefore, the countertop water purifier including the water tank can improve or guarantee the service life of the filtration system.

[0044] Preferably, the countertop water purifier further includes a water circuit board, which is snapped into the bottom of the main body of the tank and has a second water outlet and a second wastewater outlet. The second water outlet is connected between the first water outlet and the inlet of the filtration system, and the second wastewater outlet is connected between the first wastewater outlet and the wastewater outlet of the filtration system.

[0045] The bottom of the box body is provided with a first magnetic element, and the water circuit plate is provided with a second magnetic element on the side facing the box body. The first magnetic element and the second magnetic element attract each other.

[0046] In this solution, based on the interlocking connection between the body and the water circuit board, the connection reliability between the body and the water circuit board can be further improved by setting a first magnetic element and a second magnetic element that can magnetically attract each other, which is beneficial to improving the reliability of the countertop water purifier.

[0047] The positive and progressive effects of this utility model are as follows:

[0048] In this application, raw water flows out of the tank body from the first outlet, and wastewater flows into the tank body from the first wastewater outlet. The wastewater flowing into the tank body gradually mixes with the raw water. By setting a protective element at the first outlet, water will only flow into the filtration system through the protective element and the first outlet when the raw water level in the tank is greater than the height of the protective element. Therefore, by setting a protective element, the flow of water into the filtration system can be restricted when the water level is low. The water tank supplies water to the reverse osmosis system. As the water level in the raw water tank decreases, the concentration of the mixture of raw water and wastewater increases, resulting in a higher system recovery rate. A lower system recovery rate better protects the reverse osmosis membrane, thus helping to improve or ensure the service life of the filtration system. In other words, by setting a protective element, the water level flowing into the filtration system can be limited within a preset range, thereby ensuring that the system recovery rate is within a preset range, which helps to protect the reverse osmosis membrane of the filtration system, thereby improving or ensuring the service life of the filtration system. The sterilization component can sterilize the water in the tank body in a timely manner, thus helping to ensure water quality safety. Attached Figure Description

[0092] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment as an example.

[0093] like Figures 1 to 11 As shown, this embodiment provides a water tank 1 and a countertop water purifier, the countertop water purifier including the water tank 1. Specifically, regarding the water tank 1, as... Figures 1 to 10 As shown (where, Figures 3 to 5 The diagram only schematically shows a portion of the structure of the water tank 1 (the sterilization component 70, the first mounting part 108, and the mounting hole 107 are not shown). The water tank 1 includes a tank body 10, with a first water outlet 101 and a first wastewater outlet 102 at the bottom. The first water outlet 101 communicates with the interior of the water tank 1, allowing the raw water stored in the water tank 1 to flow out from the first water outlet 101; the first wastewater outlet 102 communicates with the interior of the water tank 1, allowing wastewater formed after the raw water is filtered to flow into the water tank 1 from the first wastewater outlet. The water tank 1 also includes a protective element 20 disposed within the tank body 10. The protective element 20 has a hollow cylindrical structure, with its first end located at the first water outlet 101 along the axial direction, and its second end extending in a direction away from the first water outlet 101. Along the flow direction of the raw water, the water flow is configured to sequentially pass through the second end, the first end, and the first water outlet 101 of the protective element 20. The water tank 1 also includes a sterilization component 70, which is installed on the tank body 10. The sterilization component 70 has an electrical connection end and a sterilization end. The sterilization end is located inside the tank body 10, and the electrical connection end extends to the outside of the tank body 10. The electrical connection end is sealed to the tank body 10.

[0094] In this embodiment, raw water flows out of the tank body 10 from the first outlet 101, and wastewater flows into the tank body 10 from the first wastewater outlet 102. The wastewater flowing into the tank body 10 gradually mixes with the raw water. By setting a protective element 20 at the first outlet 101, water will only flow into the filtration system through the protective element 20 and the first outlet 101 when the level of the raw water in the tank 1 is greater than the height of the protective element 20. Therefore, by setting the protective element 20, the flow of water into the filtration system can be restricted when the water level is low. The tank 1 supplies water to the reverse osmosis system. As the water level in the raw water tank 1 decreases, the concentration of the mixture of raw water and wastewater increases, resulting in a higher system recovery rate. A lower system recovery rate better protects the reverse osmosis membrane, thus improving or ensuring the service life of the filtration system. In other words, by setting the protective element 20, the water level flowing into the filtration system can be limited within a preset range, thereby ensuring the system recovery rate is within a preset range, which helps protect the reverse osmosis membrane of the filtration system and improves or ensures the service life of the filtration system. In addition, the sterilization component 70 can sterilize the water inside the tank body 10 in a timely manner, which helps to ensure the safety of water quality.

[0095] like Figure 1 , Figure 2 and Figure 9 As shown, in this embodiment, the sterilization component 70 is arranged laterally relative to the box body 10. Optionally or alternatively, the sterilization component 70 is located above the protective element along the height direction of the box body 10.

[0096] The horizontal arrangement of the sterilization component 70 reduces the space it occupies in the height of the tank body 10 and avoids affecting the top structure of the water tank 1, making operation convenient. Furthermore, positioning the sterilization component 70 above the protective element prevents interference between them, ensuring the normal operation of the water tank 1.

[0097] Furthermore, the outer wall surface of the box body 10 is provided with a mounting hole 107 and a first mounting portion 108, the mounting portion extending outward from the position on the outer wall surface of the box body 10 corresponding to the mounting hole 107. The electrical connection end has a second mounting portion 701, the sterilization end extends into the mounting hole 107 and is disposed inside the box body 10, and along the extending direction of the sterilization component 70, one end of the second mounting portion 701 corresponding to the first mounting portion 108 is provided with an external thread for threaded connection with the first mounting portion 108.

[0098] The sterilization component 70 can be easily and reliably connected to the tank body 10 via the first mounting part 108 and the second mounting part 701, which helps to simplify the overall structure of the water tank 1. In addition, the first mounting part 108 can provide a certain degree of support for the sterilization component 70, so that the sterilization component 70 can be reliably installed on the tank body 10.

[0099] In other alternative embodiments, the sterilization component 70 may also be arranged at other angles relative to the box body 10, such as vertically or at an angle.

[0100] As a preferred configuration, along the extension direction of the sterilization component 70, the end of the second mounting portion 701 furthest from the first mounting portion 108 has an external hexagonal structure.

[0101] The end of the second mounting part 701 that is far from the first mounting part 108 (i.e. the end exposed outside the box body 10) is set as an external hexagonal structure, which can facilitate the installation and removal of the sterilization component 70.

[0102] like Figure 1 , Figure 2 and Figure 10 As shown, as an example, this embodiment provides a structure for a sterilization component 70. Specifically, the sterilization component 70 includes a power cord 702, a transparent glass tube 704, a mercury lamp 703, a first sealing element 705, a second sealing element 706, and a pagoda spring 707. The mercury lamp 703 and the pagoda spring 707 are installed inside the transparent glass tube 704, with the pagoda spring 707 supported between the tail end of the mercury lamp 703 and the bottom wall of the transparent glass tube 704. The power cord 702 passes through a second mounting portion 701 and is connected to the mercury lamp 703. The second mounting portion 701 is specifically configured as a hollow fixing nut, through which the power cord 702 passes. A first sealing element 705 is provided between the fixing nut and the transparent glass tube 704, and a second sealing element 706 is provided between the transparent glass tube 704 and the outer wall of the housing body 10.

[0103] The power cord 702 is connected to an external power source.

[0104] It should be noted that in other alternative embodiments, other structural forms of sterilization components 70 in the prior art can also be used, as long as they are applicable to sterilizing the water inside the tank body 10.

[0105] like Figure 2 As shown, in this embodiment, as a preferred arrangement, the central axis of the protective element 20 is parallel to the central axis of the box body 10, and both are arranged in a vertical direction.

[0106] like Figures 2 to 4 , Figure 8As shown, the second end of the protective element 20 has a notch 201. With this configuration, based on the preset water level, the main function of the notch 201 is to allow water to flow in more easily when the water level in the tank body 10 is relatively low. Therefore, even if the water tank 1 is not necessarily flat in the installation scenario and there is a positional deviation, reliable water flow can still be achieved.

[0107] As an example, in this embodiment, the notch 201 is actually a U-shaped groove, and there is only one notch 201. The U-shaped groove is recessed downward from the top surface of the protective element 20. In an alternative embodiment, the notch 201 can also be set to other shapes, and correspondingly, the number of notches 201 can also be set to multiple. Multiple notches 201 can be arranged at intervals along the circumference of the protective element 20, or they can be scattered on the wall surface of the protective element 20.

[0108] At least as Figure 1 As shown in Figure 5, the first outlet 101 and the first wastewater outlet 102 are arranged at intervals along the horizontal direction, and the notch 201 is provided on the side of the protective element 20 away from the first wastewater outlet 102.

[0109] With this configuration, the orientation of the notch 201 is opposite to that of the first wastewater outlet 102. Its main function is to prevent excessive wastewater from flowing into the first outlet 101, allowing the wastewater to settle and settle in the water tank 1 before entering the first outlet 101, thus ensuring that the pollutants in the raw water are minimized.

[0110] In a preferred configuration, the protective element 20 can be configured to have an adjustable height along the axial direction. As previously mentioned, by setting the protective element 20, the water level flowing into the filtration system can be limited within a preset range, thereby ensuring the system recovery rate remains within a preset range. Therefore, the height of the protective element 20 can control, adjust, or influence the overall recovery rate of the filtration system. Thus, setting the height of the protective element 20 to be adjustable allows it to match filtration systems with different recovery rates and also enables it to adapt to water tanks 1 of different specifications, thus providing a wide range of applications.

[0111] Alternatively or alternatively, at least as Figure 3 and Figure 4 As shown, the water tank 1 also includes a filter element 30, which is disposed within the protective element 20. The water flow is configured to sequentially pass through the second end of the protective element 20, the filter element 30, the first end, and the first outlet 101, along the direction of the raw water flow. The filter element 30 intercepts impurities in the water, which may primarily be particulate carbon or other debris from the wastewater of the water purifier, preventing them from re-entering the system and further protecting the filtration system.

[0112] As an example, the filter element 30 corresponds to a filter screen with a mesh size of around 70.

[0113] like Figure 2 , Figure 3 and Figure 5 As shown, a waterproof component 40 is installed at both the first water outlet 101 and the first wastewater outlet 102. The waterproof component 40 can switch between a first working state and a second working state. Specifically, when the waterproof component 40 is in the first working state, either the first water outlet 101 or the first wastewater outlet 102 with the waterproof component 40 installed is in the open state. When the waterproof component 40 is in the second working state, either the first water outlet 101 or the first wastewater outlet 102 with the waterproof component 40 installed is in the closed state.

[0114] This configuration allows the waterproof component 40 to switch between a first and a second working state depending on actual usage. For example, when the water tank 1 is installed on the water circuit board 2, the waterproof component 40 switches to the first working state, at which point the water circuit is open, and the solenoid valve inside the water purifier can supply or drain water to the system simply by opening this water circuit. When the water tank 1 is removed from the water circuit board 2, the waterproof component 40 switches to the second working state, at which point the water in the water tank 1 cannot flow out, thus preventing unwanted outflow from the water tank 1.

[0115] As an example, such as Figure 2 , Figure 7 and Figure 8 As shown, the waterproof component 40 includes a sealing frame 401, a spring 402, and a sealing gasket 403. The two ends of the spring 402 are supported between the sealing gasket 403 and the sealing frame 401. The sealing frame 401 is installed inside the corresponding first water outlet 101 or first wastewater outlet 102. When the waterproof component 40 is in its first working state, the sealing gasket 403 is separated from the sealing frame 401 and supported above the sealing frame 401 to form a flow channel. One end of the flow channel is connected to the corresponding first water outlet 101 or first wastewater outlet 102, and the other end is connected to the interior of the tank body 10. When the waterproof component 40 is in its second working state, the sealing gasket 403 is in contact with the sealing frame 401 to restrict communication between the interior of the tank body 10 and the corresponding first water outlet 101 or first wastewater outlet 102.

[0116] In this embodiment, the above-described structure simplifies the waterproof component 40. Adjusting the positional relationship between the sealing gasket 403 and the sealing frame 401 reliably adjusts the working state of the waterproof component 40, simplifying the overall structure of the water tank 1 and ensuring its sealing performance. When the water tank 1 is installed on the water circuit board 2, the spring 402 releases the sealing gasket 403, and the waterproof component 40 switches to its first working state. At this time, the water circuit is open, and the solenoid valve inside the water purifier can supply or drain water to the system simply by opening this water circuit. When the water tank 1 is removed from the water circuit board 2, the sealing frame 401 falls, and the spring 402 moves downwards as well. The sealing gasket 403 firmly presses against the sealing frame 401, and the waterproof component 40 switches to its second working state. At this time, water in the water tank 1 cannot flow out, thus preventing unwanted leakage from the water tank 1.

[0117] In alternative embodiments, other structural forms of the waterproof component 40 may also be used, as long as the waterproof component 40 can be switched between the first working state and the second working state as needed.

[0118] Furthermore, such as Figures 1 to 5 As shown, the tank body 10 is also provided with a heat exchanger inlet 103 and a heat exchanger outlet 104, both of which can be opened and closed; wherein, the heat exchanger inlet 103 is used to connect the inside of the tank body 10 with the inlet of the external heat exchanger, and the heat exchanger outlet 104 is used to connect the outlet of the external heat exchanger with the inside of the tank body 10.

[0119] In this embodiment, with the above-described structure, the tank body 10 is further provided with a heat exchanger inlet 103 and a heat exchanger outlet 104 that can be opened and closed. According to actual setup requirements, the water tank 1 can be connected to an external heat exchanger, thereby expanding the applicability of the water tank 1 and meeting different usage needs.

[0120] Furthermore, in this embodiment, the heat exchanger inlet 103 and the heat exchanger outlet 104 are also equipped with the aforementioned waterproof components 40.

[0121] Furthermore, such as Figure 2 and Figure 3 As shown, the outlet end of the heat exchanger outlet 104 is also provided with a hollow columnar extension 105. The extension 105 allows the hot water flowing out of the heat exchanger outlet 104 to be delivered to a higher position, so that the hot water is on top and the cold water is on the bottom, which is more conducive to meeting the usage requirements.

[0122] like Figure 1 , Figure 2 and Figure 6As shown, the water tank 1 also includes a top cover 50, which is detachably installed on the top of the tank body 10, and the top cover 50 is provided with a vent 501 that communicates with the interior of the tank body 10. The vent 501 is provided to ensure that the pressure inside the water tank 1 is consistent with the external pressure, preventing the water tank 1 from expanding and cracking or being damaged by negative pressure during operation.

[0123] Furthermore, the top cover 50 has a front end and a rear end along the horizontal direction, with different cross-sectional dimensions at the front and rear ends. A protrusion 502 is provided on either the front or rear end of the top cover 50, and a corresponding recess 106 is provided on the box body 10 to mate with the protrusion 502. The different cross-sectional dimensions at the two ends of the top cover 50 facilitate quick differentiation between them, preventing reverse installation and thus enabling rapid installation of the top cover 50 and the box body 10. Additionally, the protrusion 502 and the recess 106 facilitate positioning of the top cover 50 and the box body 10 during installation and also prevent incorrect installation, further preventing reverse installation.

[0124] Furthermore, the portion of the top cover 50 that connects to the box body 10 has a mounting groove 503, which facilitates the installation and mating of the top cover 50 and the box body 10.

[0125] In this embodiment, the countertop water purifier includes the aforementioned water tank 1 and a filtration system (shown in the figure). The first water outlet 101 is connected to the inlet of the filtration system, and the first wastewater outlet 102 is connected to the wastewater outlet of the filtration system. As mentioned above, the structural design of the water tank 1 can improve or guarantee the service life of the filtration system. Therefore, the countertop water purifier including the water tank 1 can improve or guarantee the service life of the filtration system.

[0126] As an example, water tank 1 is made of PP material, which can solve the problem of drinking water hygiene and safety. Furthermore, to better observe the water level in water tank 1, water tank 1 is transparent.

[0127] like Figure 11 As shown, the countertop water purifier also includes a water circuit board 2, which is snapped onto the bottom of the main body 10 and has a second water outlet and a second wastewater outlet. The second water outlet connects the first water outlet 101 and the inlet of the filtration system, and the second wastewater outlet connects the first wastewater outlet 102 and the wastewater outlet of the filtration system. Figure 11 The image only schematically shows the water tank 1; the aforementioned sterilization component 70, the first mounting part 108, and the mounting hole 107 are not shown.

[0128] Combination Figure 2 , Figure 3 and Figure 5It is understood that a first magnetic element 60 is provided at the bottom of the box body 10, and a second magnetic element (not shown in the figure) is provided on the side of the water channel plate 2 facing the box body 10. The first magnetic element 60 and the second magnetic element attract each other.

[0129] In this embodiment, based on the snap-fit ​​connection between the box body 10 and the water circuit board 2, the connection reliability between the box body 10 and the water circuit board 2 can be further improved by setting a first magnetic element 60 and a second magnetic element that can magnetically attract each other, which is beneficial to improving the reliability of the countertop water purifier.

[0130] As an example, both the first magnetic element 60 and the second magnetic element are magnets.

[0131] In the water tank 1 disclosed in this embodiment, raw water flows out of the tank body 10 from the first outlet 101, and wastewater flows into the tank body 10 from the first wastewater outlet 102. The wastewater flowing into the tank body 10 gradually mixes with the raw water. By setting a protective element 20 at the first outlet 101, water will only flow into the filtration system through the protective element 20 and the first outlet 101 when the height of the raw water in the water tank 1 is greater than the height of the protective element 20. Therefore, by setting the protective element 20, the flow of water into the filtration system can be restricted when the water level is low. The water tank 1 supplies water to the reverse osmosis system. As the water level in the raw water tank 1 decreases, the concentration of the mixture of raw water and wastewater increases, resulting in a higher system recovery rate. A lower system recovery rate better protects the reverse osmosis membrane, which is beneficial for improving or ensuring the service life of the filtration system. In other words, by setting the protective element 20, the water level flowing into the filtration system can be limited within a preset range, thereby ensuring the system recovery rate is within a preset range. This helps protect the reverse osmosis membrane of the filtration system, thus improving or guaranteeing the service life of the filtration system. In addition, the sterilization component 70 can sterilize the water inside the tank body 10 in a timely manner, thereby helping to ensure water quality safety.
