Description

Technical Field

[0001] The invention relates to the technical field of water dispensers, and in particular to a desktop water purifier. Background Art

[0002] A water dispenser is a household appliance or commercial device that is primarily used to provide clean, safe drinking water. It is connected to a water source, removes impurities and contaminants from the water through a built-in filtration system, and then stores and cools or heats the water for people to drink. There are many types of water dispensers, such as desktop water dispensers, which are designed to be placed on a desktop or countertop and are suitable for use in environments with limited space such as homes, offices, and small meeting rooms.

[0003] A water dispenser generally consists of a water tank or water jug, a filtration system, an electronic control panel, a water pump and a water outlet. Users connect the water dispenser to tap water or place bottled water. The filtration system is used to remove impurities, heavy metals, chlorine and other harmful substances in the water. The water pump transports water from the water tank to the water outlet, and users can then take water from the water outlet.

[0004] At present, according to the development of the drinking water market, water tanks are divided into raw water tanks and pure water tanks. The water in the raw water tank is filtered and pumped into the pure water tank to further ensure the health of drinking water. Both the raw water tank and the pure water tank need to be installed on the main body of the water dispenser. The existing water dispensers need to consider aesthetics and practicality, and the effective use of space is very important.

[0005] After searching, it is found that in the existing technical solutions, the tabletop water dispenser is placed on the table, the raw water tank is installed at the rear of the water dispenser, and the pure water tank is installed in front of the water dispenser. When the user stands on the side of the water receiving surface and needs to replace the raw water tank, it is blocked by the water dispenser and the disassembly and assembly of the water tank cannot be observed. In addition, the machine is integrated with multiple systems, making the machine heavy and difficult to move. It is often necessary to bend down and tilt the head to observe the disassembly of the water tank. The raw water tank connected to the rear of the water dispenser is removed. When the water in the raw water tank is replaced, the water tank is removed. , it is necessary to install it to the back of the water dispenser again, and bend down and tilt your head to observe the specific situation of the water tank installation; at the same time, the user can only bend down and tilt his head to observe the disassembly and assembly of the raw water tank from one side of the water dispenser. If the installation of the raw water tank is only observed from one side, it is impossible to know whether the raw water tank and the water inlet of the water dispenser are installed in place. If it is installed only by the user's feel, it is very easy to cause the raw water tank and the water inlet of the water dispenser to be loosely connected, and the raw water tank leaks at the water inlet of the water dispenser.

[0006] Therefore, under the premise that the water dispenser is placed on the countertop, how to reduce the difficulty of users in disassembling and assembling the raw water tank and reduce the trouble of changing water, while also ensuring that the raw water tank and the water inlet of the water dispenser are installed in place, has become a technical problem that needs to be solved urgently. Summary of the invention

[0007] The main purpose of the present invention is to provide a method for reducing the difficulty of disassembling and assembling the raw water tank for users, reducing the trouble of changing water, and also ensuring that the raw water tank and the water inlet of the drinking fountain are installed in place.

[0008] In order to achieve the above-mentioned purpose, the present invention proposes a desktop water purifier, including a water dispenser body with a water receiving surface, and also including a raw water tank group, a pure water tank group and a water supply component built into the water dispenser body, which filters the water in the raw water tank group and guides it to the pure water tank group, and guides the water in the pure water tank group to the water receiving surface; wherein the raw water tank group and the pure water tank group are arranged on adjacent sides of the water receiving surface to facilitate the replacement of the raw water tank group and the pure water tank group.

[0009] Furthermore, the water dispenser body includes an outer shell and an inner shell mounted on one side of the outer shell. The inner shell is provided with a cavity for installing an instant heating module group on one side along the water receiving surface. The instant heating module group heats the water flowing from the pure water tank group to the water receiving surface.

[0010] Furthermore, the water dispenser body also includes a support base for supporting the instant heating module group, and the support base is detachably connected to the inner shell.

[0011] Furthermore, the water dispenser body is detachably connected to at least one filter element, and the filter element is connected to a pipeline between the raw water tank group and the pure water tank group.

[0012] Furthermore, the outer shell is provided with a third installation area which is arranged transversely and capable of installing the filter element inwardly from an opening at one end.

[0013] Furthermore, the installation surface of the pure water tank group is higher than the raw water tank group, and a cavity for accommodating the filter element is provided in the lifting area of ​​the pure water tank group.

[0014] Furthermore, the inner shell includes a positioning plate and a mounting plate fixed to each other, and the mounting plate is fixed to the outer shell by means of snap-fitting and / or plug-fitting.

[0015] Furthermore, the positioning plate extends toward the filter element to form a filter installation area sleeved on the peripheral wall of the filter element.

[0016] Furthermore, an electronic ice bladder is installed on the side of the mounting plate away from the instant heating module group. The electronic ice bladder, the pure water tank group and the water receiving surface are connected by a pipeline, and the pure water of the pure water tank group is guided to the electronic ice bladder for cooling through a cold water pump arranged in the pipeline, and the pure water after cooling of the electronic ice bladder is discharged from the water receiving surface.

[0017] Furthermore, the water supply assembly also includes a booster pump installed on the support seat, and the booster pump boosts the water in the pipeline flowing from the raw water tank group to the pure water tank group; the instant heating module group is arranged in the same direction as the inner shell is installed into the outer shell away from the booster pump.

[0018] The above technical solution has the following advantages:

[0019] The present invention arranges the structure of the water dispenser body so that the raw water tank and the pure water tank are arranged on adjacent sides of the water receiving surface of the water dispenser body, and simplifies the distribution of the internal structure, so that the water levels of the raw water tank group and the pure water tank group are easier to observe, and it is avoided that the raw water tank and the pure water tank are arranged behind the water dispenser body to avoid the difficulty for users to move them, which will cause trouble for users to remove and replace the raw water tank group and affect the convenience of water replacement. The removal and replacement of the raw water tank group and the pure water tank group are easier to observe, and it is avoided that insufficient light behind them or obstructed vision will cause the water tank to be installed in an improper position, resulting in water leakage at the interface.

[0020] The socket design of the outer shell and the inner shell of the present invention makes the overall installation more convenient, and fully utilizes the spatial layout in structure, so that the instant heating module group and the electronic ice tank are symmetrically arranged about the mounting plate. On the one hand, the instant heating module group is suspended and assembled between the mounting plate and the water receiving surface, and the electronic ice tank is assembled behind the mounting plate. The heat dissipation mesh facilitates the heat dissipation of the electronic ice tank, avoids contact between personnel and the emitted heat, and effectively isolates users to increase the comfort of use. On the other hand, the reasonable allocation of the installation space of the instant heating module group and the electronic ice tank improves the utilization rate of the space. The pure water outlet pipe of the pure water tank group helps to branch the pipe toward the instant heating module group and the electronic ice tank, which helps to save the length of the pipe.

[0021] The present invention raises the installation platform of the pure water tank group, and arranges the filter element in the raised area. The structure of the pure water tank group is reasonably designed to free up a reasonable installation space for the filter element, thereby improving the utilization rate of the space. The raw water inlet of the filter element is placed close to the booster pump, which helps to improve the simplicity of the pipeline. At the same time, the horizontal placement of the filter element makes it more convenient for users to replace it, so as to avoid the need to use a bench to raise the filter element when replacing the vertically placed filter element.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not constitute a limitation to the present invention.

[0035] like Figure 1 and Figure 5As shown, a tabletop water purifier includes a water dispenser body 10 with a water receiving surface. The water dispenser body 10 is equipped with a water supply component that can filter the water in the raw water tank group 20 and guide it to the pure water tank group 30, and guide the water in the pure water tank group 30 to the water receiving surface; the raw water tank group 20 and the pure water tank group 30 are arranged on the adjacent sides of the water receiving surface to facilitate the replacement of the raw water tank group 20 and the pure water tank group 30. Among them, the water dispenser body 10 guides the water in the pure water tank group 30 from the water receiving surface through the water supply component for people to collect water for drinking. This application is as follows Figure 5 The water receiving area 103 shown in the figure is arranged on the water receiving surface, which is convenient for users to receive water again. When the desktop water purifier is placed, in order to ensure the convenience of use, the water dispenser body 10 is placed on the countertop or tabletop, and the water receiving surface is close to the edge of the countertop or tabletop to facilitate water receiving; the raw water tank group 20 and the pure water tank group 30 can be arranged on the same side of the water receiving surface, so that the raw water tank group 20 and the pure water tank group 30 are adjacent, and the water levels of the raw water tank group 20 and the pure water tank group 30 can be clearly seen, and it is convenient to disassemble and assemble from the side of the water dispenser body 10; it can also be arranged on both sides of the water receiving surface. In the present application, it is preferred that the raw water tank group 20 and the pure water tank group 30 are arranged on both sides of the water receiving surface. The purpose is to take into account the beauty of the overall structure and the overall water capacity of the raw water tank group 20 and the pure water tank group 30.

[0036] Figure 5-Figure 7 As shown, specifically, a control circuit board is built into the water dispenser body 10, and an operation panel 106 is also provided on the water receiving surface. The control circuit board is used to display the operation panel 106. The operation panel 106 can observe the specific situation in the water dispenser body 10 at any time, which includes but is not limited to the purpose, water volume, and water temperature. The operation panel 106 is also provided with various buttons, which receive signals through the processor of the control circuit board after being pressed to quickly obtain the required instructions, such as pure water with a specific temperature and water volume. For pure water with a specific water flow, it can obtain a certain amount of pure water by installing a water level monitoring component 113 on the pure water tank group 30 and the raw water tank group 20. The water level monitoring component 113 measures the liquid level difference in the pure water tank group 30 to obtain a certain amount of pure water; in addition, the water output of the water dispenser can also be adjusted by means of an electromagnetic valve, that is, the control circuit board controls the opening and closing of the electromagnetic valve; a Hall flow meter can also be used to measure the water flow through the pulse signal generated by the rotation of the impeller in the magnetic field, thereby controlling the switch of the water pump.

[0037] Figure 5-Figure 7As shown, for a specific water outlet temperature of the pure water tank group 30, the water supply component can also adopt a combination of an electronic ice tank 110 and an instant heating module group 111. The instant heating module group 111 is a prior art, and a commercially available instant heating module is adopted, or an instant heating module applied for by the company can be adopted. The purpose is to achieve rapid heating of the water body and increase the heating rate of the water body. In the pipeline of the pure water tank group 30 flowing toward the instant heating module group 111, another pipeline flowing to the electronic ice tank 110 is also provided, and a cold water pump 114 is also installed on the pipeline. When the user issues a cold water demand instruction through the operation panel 106, the cold water pump 114 starts to work, and the filtered pure water is pumped out from the pure water tank group 30 and enters the electronic ice tank 110 for cooling. After the cooled water The hot water flows out through the water spout of the water receiving surface; the instant heating module group 111 heats the water flowing from the pure water tank group 30 to the water receiving surface. If hot water is needed, a hot water pump 115 is installed on the pipeline between the instant heating module group 111 and the water spout. The water in the pure water tank group 30 is pumped out by the hot water pump 115, heated by the instant heating module group 111, and flows from the water spout to the water receiving surface. The temperature of the water outlet from the instant heating module group 111 can also be detected by a temperature sensor. There are many types of temperature sensors, such as model DS18B20, which transmit temperature data to the processor of the control circuit board. After the processor of the control circuit board receives the water outlet temperature of the instant heating module group 111, it compares the required specific temperature with the detected temperature, and adjusts the power of the instant heating module group 111 through an algorithm, such as a PID algorithm, to reduce temperature deviation, improve the stability and response speed of the system, so as to quickly reach the temperature value preset by the operation panel 106, so that the water dispenser body 10 can flow out water of a specific temperature.

[0038] like Figure 6-Figure 8As shown, the water dispenser body 10 includes an outer shell 101 and an inner shell 107 mounted on one side of the outer shell 101. The inner shell 107 is provided with a cavity for installing the instant heating module group 111 on one side along the water surface direction, wherein the inner shell 107 can only be installed from one side of the outer shell 101. The top cover plate of the outer shell 101 is detachable, and its rear cover plate is a heat dissipation cover plate. After the heat dissipation cover plate is installed, its heat dissipation mesh dissipates heat to the water dispenser body 10, which helps to improve the heat dissipation effect of the water dispenser body 10, and the heat is dissipated from the rear part of the water dispenser body 10, which is effectively isolated from the user to increase the comfort of use. The inner shell 107 is designed with a corresponding offset according to the shape of the outer shell 101, so that its installation method is more convenient; the electronic ice container 110 is installed on the side of the inner shell 107 away from the instant heating module group 111, and two installation methods can be selected. One is to install the instant heating module group 111 between the inner shell 107 and the side wall where the water receiving surface is located, and the electronic ice container 110 is installed between the inner shell 107 and the rear side wall of the outer shell 101; the second is to install the instant heating module group 111 between the inner shell 107 and the rear side wall of the outer shell 101, and the electronic ice container 110 is installed between the inner shell 107 and the side wall where the water receiving surface is located. In this application, the first installation method is preferably used, as shown below.

[0039] The inner housing 107 includes a positioning plate 1071 and a mounting plate 1073 fixed to each other. The mounting plate 1073 is fixed to the outer housing 101 by means of a snap connection and / or a plug connection. The positioning plate 1071 is attached to the inner wall of the outer housing 101 and to the side wall at the second mounting area 104. A groove for assembling a control circuit board is provided on one side of the positioning plate 1071. After the control circuit board is installed, the cover plate is closed to protect the control circuit board. The tops of the mounting plate 1073 and the positioning plate 1071 are mutually buckled with the outer housing 101, and can also be connected by a shaft. The inner shell 107 is fixed by plugging in, or combining the two. In this process, when the inner shell 107 is sleeved on the outer shell 101, the positioning plate 1071 and the mounting plate 1073 can be directly snapped or plugged into the outer shell 101 to complete the fixation; the instant heating module group 111 is arranged between the mounting plate 1073 and the side wall facing the water receiving surface, and the instant heating module group 111 is provided with hardware, which is fixedly installed with the protrusion on the mounting plate 1073, so that the instant heating module group 111 is suspended, so that the temperature of the surface of the instant heating module group 111 is separated from the inner shell 107 and the outer shell 101.

[0040] Specifically, the mounting plate 1073 is L-shaped, which limits the instant heating module group 111 to the side of the outer shell 101 facing the water receiving surface. The end of the mounting plate 1073 away from the water receiving surface has a platform, and the platform is used to install the electronic ice bladder 110. The lower end surface of the mounting plate 1073 is also equipped with a plug-in portion 1074 plugged in around the booster pump 109. The support seat 108 includes a seat body 1081, a plug-in seat 1082 fixed to the seat body 1081 and arranged on the periphery of the booster pump 109, and the top of the plug-in seat 1082 is plugged into the plug-in portion 1074. After the connection, a cavity for storing the booster pump 109 is formed between the mounting plate 1073 and the base body 1081. Since the water supplied to the electronic ice tank 110 and the water supplied to the instant heating module group 111 are both from the pure water tank group 30, multiple pipes need to be arranged at the pure water outlet of the pure water tank group 30. The electronic ice tank 110 and the instant heating module group 111 are separated from each other by the mounting plate 1073. The pure water outlet pipe of the pure water tank group 30 can form a branch between the electronic ice tank 110 and the instant heating module group 111 to maximize the use of the space inside the water dispenser body 10.

[0041] Since the heat emitted by the electronic ice container 110 during cooling needs to be discharged in time, it is installed at the rear of the water dispenser body 10. The heat dissipation mesh port of the heat dissipation cover is aimed at the fan of the electronic ice container 110, so as to facilitate the timely discharge of the heat emitted by the electronic ice container 110; and the heat emitted by the instant heating module group 111 is absorbed by the pure water in time, so there is no need for heat dissipation treatment.

[0042] like Figure 1-Figure 5 As shown, the outer shell 101 is provided with a first installation area 102 on one side of the water receiving surface, and a second installation area 104 on the other side. The first installation area 102 is used to install the raw water tank group 20, and the second installation area 104 is used to install the pure water tank group 30. The installation method of the raw water tank group 20 and the pure water tank group 30 are both detachable connections, and the installation method is as follows:

[0043] A guide rod is provided in the first installation area 102 along the height direction of the outer shell 101, so that the raw water tank group 20 can be gradually moved down from the top of the guide rod to the table of the first installation area 102 until the raw water tank group 20 is connected with the raw water inlet of the water dispenser body 10, and the guide rod plays a guiding and limiting role for the raw water tank group 20;

[0044] As an implementation method of this embodiment, the guide rod of the first installation area 102 is arranged along the width direction of the outer shell 101, so that the raw water tank group 20 can move along one end of the guide rod to the middle of the first installation area 102, and after falling at this position, it is connected with the raw water inlet of the water dispenser body 10; or the raw water inlet and the raw water outlet are arranged at the rear of the outer shell 101, so that after the raw water tank group 20 moves to the first installation area 102, it is directly connected with the raw water inlet and the raw water outlet along the moving direction, and the raw water outlet can be pumped through the pipe extending into the bottom of the raw water tank group 20; no matter what operation is performed, it is only necessary to ensure that the raw water at the bottom of the raw water tank group 20 can be pumped into the pure water tank group 30. For the installation in the width direction of the raw water tank group 20, it can be embedded in the cabinet of the desktop water purifier, so that the raw water tank group 20 can be directly pulled out horizontally to avoid interference with the cabinet panel at the top of the desktop water purifier when the raw water tank group 20 is pulled out.

[0045] As an implementation method of this embodiment, the table top of the first installation area 102 may also be provided with a protrusion or a groove that complements the raw water tank group 20, so that the raw water tank group 20 can be firmly installed on one side of the water dispenser body 10, and connected to the raw water inlet and the raw water outlet along the moving direction of the raw water tank group 20, which will not be repeated here.

[0046] The above installation method is also applicable to the second installation area 104 and the pure water tank group 30, except that the pure water tank group 30 is connected to the pure water inlet and the pure water outlet in the second installation area 104.

[0047] like Figure 6-Figure 8 As shown, the water dispenser body 10 also includes a support base 108 supporting the instant heating module group 111, and the support base 108 is detachably connected to the inner shell 107. The water supply assembly also includes a booster pump 109 installed on the support base 108. The booster pump 109 is used to pressurize the water in the pipelines of the raw water tank group 20 and the pure water tank group 30 in sequence. The direction of the instant heating module group 111 away from the booster pump 109 is arranged in the same direction as the inner shell 107 is installed into the outer shell 101. Among them, when the inner shell 107 is sleeved in the outer shell 101, the electronic ice bladder 110 and the instant heating module group 111 are directly installed between the inner shell 107 and the outer shell 101, the inner shell 107 and the support base 108 are assembled with each other, and the booster pump 109 is installed in the space between the inner shell 107 and the support base 108, so that the entire assembly process is simpler and faster.

[0048] like Figure 1-Figure 5As shown, the water dispenser body 10 is detachably connected with at least one filter element 40, and the filter element 40 is connected to the pipeline between the raw water tank group 20 and the pure water tank group 30. The outer shell 101 is provided with a third installation area 105 which is horizontally arranged and can install the filter element 40 inward from the opening at one end. The water flowing from the raw water tank group 20 to the pure water tank group 30 is filtered by the filter element 40. A plurality of filter elements 40 can be provided to improve the filtering effect on the raw water tank group 20. For the present application, in order to facilitate the replacement of the filter element 40, only a single filter element 40 is provided in the present application.

[0049] like Figure 5-Figure 8 As shown, the installation surface of the pure water tank group 30 is higher than the raw water tank group 20, and a cavity for accommodating the filter element 40 is provided in the lifting area of ​​the pure water tank group 30, and the third installation area 105 is provided in the cavity. Since the water of the pure water tank group 30 comes from the filtration of the raw water tank group 20, the filter element 40 cannot filter the water of the raw water tank group 20 and flow into the pure water tank group 30. Therefore, the water capacity of the pure water tank group 30 is smaller than the water capacity of the raw water tank group 20. Therefore, the installation surface of the pure water tank group 30 is raised, and the lifted area is designed as the third installation area 105 of the filter element 40, so as to more effectively utilize the space of the water dispenser body 10 and compress the volume of the product. A support plate 1083 is provided at a position of the seat body 1081 close to the filter element 40, and the positioning plate 1071 extends toward the direction of the filter element 40 to form a sleeve on the peripheral wall of the filter element 40, and a filter installation area 1072 accommodating the water inlet of the pure water tank group 30 is provided on its side wall, and the filter installation area 1072 is placed on the support plate 1083, and the top of the filter installation area 1072 is limited by the installation platform of the second installation area 104, so that its position can be directly fixed after the inner shell body 107 and the outer shell body 101 are assembled, and the filter element 40 can extend into the filter installation area 1072 from the open end of the third installation area 105, so that the installation of the filter element 40 is more precise.

[0050] After the filter element 40 filters the raw water, there is still water that fails to pass through the reverse osmosis membrane of the filter element 40 and cannot flow into the pure water tank group 30. Therefore, this part of the water needs to be returned to the raw water tank group 20. A reflux valve 112 is also connected to the pipeline between the wastewater discharge port of the filter element 40 and the raw water tank group 20. Under the action of the booster pump 109, the reflux valve 112 is opened by the control circuit, so that the remaining wastewater in the filter element 40 flows from the reflux valve 112 to the raw water tank group 20. Therefore, a wastewater return port is also set in the first installation area 102 of the present application.

[0051] Specifically, the filter element 40 of the present application is placed horizontally, which is helpful for users to replace it, and the specific method and position are as follows:

[0052] Embodiment 1:

[0053] like Figure 1 , Figure 2 and Figure 7As shown, the filter element 40 is installed from the third installation area 105 on the water outlet side of the water dispenser body 10, so that the filter element 40 extends from the open end of the third installation area 105 of the outer shell 101 to the filter installation area 1072, and after the filter element 40 is installed in place, it is buckled through the end cover to improve the overall appearance, and the water inlet and outlet ends of the filter element 40 are facing the rear of the water dispenser body 10, that is, close to the branch pipe of the pure water tank group 30, which helps to save the length of the pipe.

[0054] Embodiment 2:

[0055] like Figure 3 and Figure 7 As shown, the filter element 40 is installed from the side of the water outlet surface of the water dispenser body 10, so that the filter element 40 extends from the open end of the third installation area 105 of the outer shell 101 to the filter installation area 1072, and is buckled through the end cover after the filter element 40 is installed in place to improve the overall aesthetics. The water inlet and outlet ends of the filter element 40 face the raw water tank group 20, and the support plate 1083 also changes its position following the filter installation area 1072. After the inner shell 107 and the support seat 108 are installed, the space reserved under the installation plate 1073 is convenient for the piping of the booster pump 109 and the filter element 40, thereby improving the compactness of the pipeline layout and providing space utilization.

[0056] Embodiment three:

[0057] like Figure 4 As shown, the filter element 40 can be installed from the side opposite to the water outlet surface of the water dispenser body 10, that is, the filter element 40 is installed from the rear of the water dispenser body 10, so that the filter element 40 extends from the open end of the third installation area 105 of the outer shell 101 to the filter installation area 1072, and after the filter element 40 is installed in place, it is buckled through the end cover to improve the overall appearance. This solution can effectively hide the filter element 40 to prevent the user from buckling the end cover without reason, which may easily cause the filter element 40 to loosen and affect the impurity removal effect of the raw water.

[0058] For the above three implementations, no matter which scheme is used, the filter element 40 is placed horizontally to prevent the original filter element 40 from being taken out from the top of the water dispenser body 10. The filter element 40 itself has a certain length. If the water dispenser body 10 is placed a little higher, the user may even need to use a stool to take out the filter element 40, which increases the difficulty of the user's replacement of the filter element 40 and greatly affects the user's experience.

[0059] like Figure 5 and Fig. 9As shown, the raw water tank group 20 includes a raw water tank body 201 and a raw water tank cover 202 on the top. A raw water tank return port 203 and a raw water tank outlet 204 are also provided at the bottom of the raw water tank body 201. The raw water tank outlet 204 is used to supply water to the pure water tank group 30, and the water flows into the pure water tank group 30 after being pressurized by the booster pump 109 and removed by the filter element 40. The waste water of the filter element 40 is connected to the raw water tank return port 203 through a pipeline, and is opened or closed by the reflux valve 112 on the pipeline, so that the remaining waste water of the filter element 40 can flow back into the raw water tank body 201.

[0060] like Figure 5 , Figure 8 and Fig.10 As shown, the pure water tank group 30 includes a pure water tank body 301 and a pure water tank cover 302 that is snapped on the top, a pure water tank handle 305 is also installed on the side of the pure water tank body 301, and a pure water tank water inlet 303 and a pure water tank water outlet 304 are also provided at the bottom of the pure water tank body 301, the pure water tank water inlet 303 and the pure water tank water outlet 304 are both connected to the outer shell 101 through the mounting platform of the second mounting area 104 and the filter mounting area 1072, the pure water tank water inlet 303 is connected to the pure water outlet of the filter element 40, and the pure water tank water outlet 304 is connected to the water inflow pipeline of the instant heating module group 111.

[0061] During use, the raw water tank group 20 flows out through the raw water tank outlet 204, and after being pressurized by the booster pump 109 and removed by the filter element 40, it flows from the pure water tank inlet 303 to the pure water tank group 30, completing the filtration of raw water to pure water; if the user needs to drink water, the pure water in the pure water tank group 30 flows out from the pure water tank outlet 304, and is quickly heated by the instant heating module group 111, and after rapid heating, it flows from the hot water pump 115 to the water nozzle of the water receiving surface, and at the same time, the value detected by the temperature sensor at the water outlet end of the instant heating module group 111 is displayed in real time on the operation panel 106, and the user can also adjust the temperature as needed; if cold water is needed, the pure water outflow pipeline of the pure water tank outlet 304 opens the cold water pump 114 from the branch, and the cold water pump 114 guides the pure water to the electronic ice tank 110, and the water after refrigeration and cooling flows out through the water outlet nozzle.

[0062] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
