The water tank module 300 may be detachably connected to the water purification module 100. The water tank module 300 may include one or more of a water tank or a pressure tank. The tank module 300 may be used to store raw water. When the water purification module 100 requires water production, the water tank module 300 may provide raw water for the water purification module 100. Illustratively, the example of including a tank within the tank module 300 may include, in addition to the tank, accessories that cooperate with the tank, such as one or more of a suction pump, a level switch, or a water inlet solenoid valve. The accessories are used with the tank to further improve the functionality of the tank module 300. The tank module 300 may have a tank outlet 302. The tank outlet 302 may be provided at the bottom of the tank module 300, and raw water in the tank module 100 may be supplied to the water purification module 100 by gravity. The water purification module 100 may have a raw water inlet 101. Taking the water purification module 100 with a pre-filter as an example, the raw water inlet 101 of the water purification module 100 may be communicated with a water inlet of the pre-filter. The tank outlet 302 may communicate with the raw water inlet 101 when the tank module 300 is connected to the water purification module 100. Illustratively, as shown in fig. 3 to 4, the connection of the water tank module 300 to the water purification module 100 may be achieved by a waterway interface connection.

Illustratively, a first sensor and a first communication circuit may be disposed on the heating base 210. The first sensor may be configured to detect first kettle information on the heating base 210 and generate a first signal to the first communication circuit. A controller and a second communication circuit may be provided in the water purification module 100. The second communication circuit may establish communication with the first communication circuit when the heating base 210 is connected to the water purification module 100. The second communication circuit receives the first signal and sends it to the controller when the heating base 210 is connected to the water purification module 100. The controller can be used for controlling the desktop water purifier to stand by based on the first signal. In one embodiment, the first sensor may comprise one or more of a contact switch, a proximity switch, a pressure sensor, or a weight sensor. When the first sensor comprises a contact switch or a proximity switch, the first sensor may generate a corresponding electrical signal when the hot water kettle 220 is placed on the heating base 210. In this case, the first hot water kettle information includes information on whether the hot water kettle 220 is present on the heating base 210. When the first sensor comprises a pressure sensor or a weight sensor, the pressure sensor or the weight sensor may be used to detect the pressure or the weight carried by the heating base 210, respectively, and generate a corresponding electrical signal. In this case, the first hot water kettle information includes pressure information and weight information on the heating base 210. The first signal includes first hot water kettle information. For example, the first communication circuit and the second communication circuit may employ various existing communication circuits. When the heating base 210 is connected to the water purification module 100, the first communication circuit and the second communication circuit may be wired through their respective electrical connectors, so as to transmit electrical signals between the first communication circuit and the second communication circuit. Of course, in other embodiments, the first communication circuit and the second communication circuit may also implement the transfer of the electrical signal by means of a wireless connection, such as a bluetooth connection or a wireless network connection. The first sensor may generate a first electrical signal when the hot water kettle 220 is placed on the heating base 210. In one embodiment, the first electric signal may be used as a standby signal of the desktop water purifier. After the controller receives the first electric signal, the desktop water purifier can be controlled to enter a standby state. The standby state can be a preparation state for the desktop water purifier to enter water making or heating operation and the like. In some embodiments, the standby state may also include a state in which the amount of water, the temperature of water, etc. in the hot water kettle 220 is detected. The controller can automatically control water making or heating and the like according to the detection result. The user can also control water making or heating and the like in a manual mode.

It should be noted that the controller may be built by using electronic components such as a timer, a comparator, a register, and a digital logic circuit, or may be implemented by using processor chips such as a single chip microcomputer, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), and an Application Specific Integrated Circuit (ASIC), and peripheral circuits thereof.

Therefore, with the desktop water purifier provided with the device, the controller controls the desktop water purifier to enter a standby state through the first signal generated by the first sensor so as to enable the desktop water purifier to be started and prepared. Therefore, the desktop water purifier can start to work at any time according to the instruction of the user.

Further, the desktop water purifier can further comprise a heating control element and a water purifying control element which can be controlled by a user. The heating control member and the water purification control member may be disposed on the water purification module 100, on the heating base 210, or in any other suitable position. The controller can also be used for activating the heating control element and the water purifying control element when the desktop water purifier is in a standby state. The heating manipulation control and the water purification manipulation control may be operated in response to a manipulation of a user when activated. When the heating control part and the water purification control part are not activated, even if the user performs corresponding operation on the heating control part and the water purification control part, the controller can not control the heating module and the water purification module to perform corresponding operation. The heating module may be activated by the heating control to heat the water in the hot water kettle 220. The water purification module can be started through the water purification control piece so as to prepare water purification in the hot water kettle 220. For example, the heating control and the water purification control may include one or more of a manual operation button or a voice recognition component. When desktop purifier standby, heating control spare and water purification control spare can be activated, that is to say, when desktop purifier is in standby state, heating control spare and water purification control spare can respond to user's operation and generate corresponding signal of telecommunication, and the controller can carry out corresponding operation according to signal of telecommunication control water purification module and heating module. It can be understood that the first electric signal for enabling the desktop water purifier to enter the standby state can be regarded as a protection switch, and only after the user places the hot water kettle 220 on the heating base 210, the user can further operate the water making or heating, so that the situation that the hot water kettle 220 is not placed on the heating base 210 is prevented, the user performs misoperation on the heating operation control component or the water purifying operation component, and the use safety of the desktop water purifier is improved.

Illustratively, the first sensor may comprise a weight sensor. The weight sensor may be used to weigh the hot water kettle 220. In this case, the first hot water kettle information includes the weight of the hot water kettle 220. In one embodiment, the controller may determine from the first kettle information whether the weight of the kettle 220 is above a first weight threshold. The first weight threshold may be the weight of the hot water kettle 220 when empty. When no hot water kettle 220 is placed on the heating base 210, the controller will not control the desktop water purifier to enter a standby state.

The advantage of using a weight sensor for the first sensor is that the first signal generated by the first sensor comprises weight information of the hot water kettle 220, so that wires or connections for transmitting electrical signals between the hot water kettle 220 and the heating base 210 can be avoided. On the one hand, can make things convenient for thermos 220 to take from heating base 210 like this, on the other hand, even the overflow phenomenon appears in thermos 220, also can not cause the soaking to the link between thermos 220 and the heating base 210, improved the safety in utilization.

Illustratively, the heating module 200 may also include a tray. The tray may be disposed on the heating base 210 concentrically with the hot water kettle 220 placement area on the heating base 210. The hot water kettle 220 may be placed on the tray when connected to the heating base 210. The first sensor may be located between the tray and the heated base 210. The first sensor may be used to weigh the tray and the hot water kettle 220. The tray may have a disk-like structure, which may function to support the hot water kettle 220. Further, the storage tray may be provided with a positioning portion, and when the hot water kettle 220 is placed on the storage tray, the positioning portion may fixedly connect the hot water kettle 220 and the storage tray relatively. In one embodiment, the positioning portion may include a protrusion provided at the center of the tray, and the bottom of the hot water kettle 220 may be provided with a recess, and the protrusion on the tray and the recess on the bottom of the hot water kettle 220 may be engaged when the hot water kettle 220 is placed on the tray. The area of the storage tray may be larger than that of the bottom surface of the hot water kettle 220, and a bead extending upward may be provided around the storage tray to prevent the hot water kettle 220 from overflowing out of the storage tray.

It can be seen that the tray can be used to hold the hot water kettle 220 so that the hot water kettle 220 may be more stably placed on the first sensor. Further, since the heating module 200 is provided with the storage tray, water overflowing from the hot water kettle 220 can be collected through the storage tray, the overflowing water is prevented from contacting the first sensor, and the first sensor is protected.

For example, a second sensor may be disposed on the heating base 210, the hot water kettle 220 and/or the water purification module 100. The second sensor may be used to detect second kettle information on the heating base 210 and generate a second signal to the first communication circuit. The second communication circuit may establish communication with the first communication circuit when the heating base 210 is connected to the water purification module 100. The second communication circuit receives a second signal and sends it to the controller when the heating base 210 is connected to the water purification module 100. The controller may be configured to control the water purification module 100 to be shut down when it is determined that the hot water kettle 220 on the heating base 210 is full of water based on the second signal. In one embodiment, the second sensor may comprise a level sensor, such as a level switch, a pressure sensor, or a weight sensor. The second sensor may be disposed within the hot water kettle 220 when the second sensor comprises a level switch that generates a second signal indicative of full water when the hot water kettle 220 is full of water. In this case, the second hot water kettle information includes information that the hot water kettle 220 on the heating base 210 is full of water. When the level sensor is a level meter, a second sensor may be provided on the hot water kettle 220 or the water purification module 100. In this case, the second hot water kettle information includes the liquid level information inside the hot water kettle 220. The second sensor may be disposed within the hot water kettle 220 when the second sensor comprises a level switch that generates a second signal indicative of full water when the hot water kettle 220 is full of water. In this case, the second hot water kettle information includes that the hot water kettle 220 on the heating base 210 is full of water. When the second sensor includes a pressure sensor or a weight sensor, the second sensor may be disposed on the heating base 210. A pressure sensor or a weight sensor may be used to detect the pressure or weight carried by the heating base 210, respectively, and generate a corresponding electrical signal. In this case, the second hot water kettle information includes pressure information and weight information on the heating base 210. The second signal includes second hot water kettle information. The controller controls the water purification module 100 to stop producing water into the hot water kettle 220 after determining that the hot water kettle 220 is full of water according to the second signal.

Therefore, whether the hot water kettle 220 is full of water or not can be detected by arranging the second sensor, and the water is prevented from overflowing from the hot water kettle 220 when the water purification module 100 produces water to the hot water kettle 220.

Further, the second sensor and the first sensor may be the same weight sensor. In one embodiment, the second sensor may also be a weight sensor and be identical to the first sensor. The functions of the first sensor and the second sensor are realized by using the same weight sensor, so that the number of parts of the desktop water purifier can be reduced, and the control logic can be relatively simple. The controller can realize the above-mentioned functions of preventing water overflow and preventing misoperation only by judging whether the weight borne by the heating base 210 is less than the weight when the kettle is empty or whether the weight reaches the weight when the kettle is full according to the information of the hot water kettle detected by the weight sensor.

Illustratively, the filter assembly 110 may further include a reverse osmosis filter cartridge 111 and a booster pump 112. The outlet of the booster pump 112 may be connected to the raw water port of the reverse osmosis cartridge 111. The pure water port of the reverse osmosis cartridge 111 may be connected to the pure water outlet 102. The water purification that reverse osmosis filter element 111 accessible reverse osmosis membrane preparation can directly be drunk, and booster pump 112 can improve the water pressure of the raw water that gets into reverse osmosis filter element 111 to improve the filterable efficiency of reverse osmosis filter element 111, improve pure water system water speed.

Illustratively, in embodiments where the desktop water purifier includes a tank module 300 and a reverse osmosis cartridge 111, the tank module 300 may have not only a tank outlet 302, but also a tank return 303. The tank outlet 302 may be used to allow raw water in the tank module 300 to enter the water purification module 100. The tank return port 303 may be used to receive concentrated water generated by the water purification module 100 when filtering. The water purification module 100 may have a raw water inlet 101 and a concentrated water outlet 103. The raw water inlet 101 may be communicated to an inlet of the booster pump 112, and the concentrated water outlet 103 may be communicated to a concentrated water port of the reverse osmosis filter element 111. Wherein, when the water tank module 300 is connected to the water purification module 100, the water tank outlet 302 may communicate with the raw water inlet 101. The tank return port 303 may communicate with the concentrate outlet 103. In one embodiment, the tank module 300 may have a raw water tank and a rich water tank disposed therein in spaced relation to each other. The raw water tank may be used to provide raw water to the water purification module 100, and the concentrated water tank may be used to receive concentrated water filtered by the water purification module 100. Wherein the raw water and the concentrated water are separately provided. The user can process according to the water level condition of each water tank, such as adding raw water into the raw water tank or discharging concentrated water in the concentrated water tank. In another embodiment, the water tank module 300 may not distinguish between raw water and concentrated water, and the water tank outlet 302 and the water tank return 303 may both communicate with the same water tank. The water purification module 100 can extract raw water from the water tank, and the concentrated water generated by the water purification module 100 after filtration can be returned to the water tank and mixed with the raw water in the water tank to form new raw water to be taken by the water purification module 100 again. The user can judge whether need to change the water in the water tank according to the residual water volume in the water tank, or the TDS value of the water in the water tank.

With this arrangement, the water tank module 300 can receive the concentrated water generated by the reverse osmosis cartridge 111 upon filtration, rather than being discharged directly. Like this, can avoid being connected desk-top purifier and water drainage pipe to the position can be moved at will when realizing desk-top purifier and using, and need not consider for the emission of dense water, has improved the user and has experienced desk-top purifier's use, has also improved the flexibility of desk-top purifier when using.
