Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pet intelligent products, and particularly relates to a magnetic driving drainage device and a water dispenser. BACKGROUND

[0002] The prior art is a pet automatic water dispenser, which uses a submersible pump as a power device to transport the stored water in a water tank to a water tray and forms a flowing mode to supply water for pets.

[0003] The pet water dispenser with an electric water pump is soaked in water for a long time, and is prone to risks such as electric leakage and short circuit.

[0004] There are also water dispensers driven by electromagnetism or magnetism, but the driving mechanism is complex and not easy to disassemble, so that cleaning is inconvenient and dirt is easily accumulated;

[0005] Some water dispensers have a filter structure, but the filter is prone to blockage, which causes water outflow to be blocked. SUMMARY

[0006] In view of the above analysis, the embodiments of the present application aim to provide a magnetic driving drainage device and a water dispenser to solve the problems of the prior art, such as inconvenient cleaning, low water outflow efficiency, affecting energy efficiency, difficulty in disassembly, and complex structure.

[0007] The technical scheme provided by the embodiments of the present application is implemented by the following scheme:

[0008] A magnetic driving drainage device is arranged in a water storage tank of a pet water dispenser, which comprises a main body and a fan blade cover.

[0009] The top end of the main body has an outflow part, and the bottom is detachably connected to the fan blade cover without using fasteners; wherein the fan blade cover is provided with an impeller, and a plurality of magnet units are arranged on the impeller at intervals; the magnetic force is adsorbed and transmitted by the magnet driving part on the driving mechanism on the base of the water dispenser.

[0010] The cross section of the outflow part is smaller than that of the top of the main body, and the outflow part has a neck part.

[0011] The main body is further provided with an inner bracket, the side wall and top wall of the inner bracket are provided with flow-through holes, and at least one group of filter core packages are arranged inside.

[0012] The inner wall between the inner bracket and the main body forms a flow channel, and the flow channel is in communication with the inner space of the inner bracket through the flow-through holes.

[0013] The 'positioning' here means that the water pump is in contact with the water tank by direct placement without additional fixing means, or the water tank has an indication position for direct placement. When installing, the water pump is placed in the designated area, and the magnetic force is automatically attracted, and the magnetic force feedback can be felt by hand. Even if there is no installation alignment, the driving adsorption completely avoids the problem of not working due to improper installation during the magnetic transmission process.

[0014] The impeller of the present application is arranged on the impeller disc, and does not have a pump body shell unit, but is directly connected with the water inlet main body in a detachable manner without fasteners, such as buckling, or easily detachable connection modes such as sleeve connection and plug-in connection.

[0015] In this way, the user can easily detach the main body and the impeller disc for cleaning, and only these two components are in the water tank, so that the water tank is clean and hygienic, and is not easy to hide dirt and is easy to clean.

[0016] The impeller disc can be directly adsorbed in the water tank by the driving mechanism on the base to play an auxiliary positioning role, and the user can also easily take out the impeller disc for separate cleaning of the impeller. More importantly, the material of the water tank is not limited, which can be plastic, metal, or even a combination of the two, so that the appearance of the water tank can be more liked by the user.

[0017] Compared with the water dispensers on the market, the connection between the water pump and the water tank has a matching relationship, which is not convenient to detach and clean. The present application can nest more than two water tanks, for example, the outer layer is a frosted translucent water tank, and the inner layer is a bright metal water tank. The outer water tank constitutes an outer shell, and the inner water tank is used for water storage. At the same time, the inner water tank or the outer water tank can be used alone, as long as the driving force and the adsorption force between the driving mechanism and the impeller disc do not affect the water outlet. Of course, the water tank can also be made of ceramic, glass, or stone material.

[0018] The outlet portion is smaller than the cross-sectional area of the main body, which facilitates the water outlet with pressure and makes it easier to flow out. At the same time, the outlet portion has a neck-in portion inside to further give the water flow a certain resistance, thereby enhancing the water outlet pressure and making more internal water flow preferentially flow into the filter bin for filtration before flowing out.

[0019] The inner bracket in the main body divides the main body into two space regions, a flow channel and a filter area, which are communicated, so that even if the filter area is blocked, the water flow is not affected.

[0020] The filter bag assembly is arranged in the flow guide device to make the water dispenser have multiple filtering modes.

[0021] The upper part of the inner bracket forms a flow channel narrower than other areas between the inner part of the main body, so that the water flow is preferentially discharged from the outlet after passing through the filter core package; when the filter core is blocked, the water flow is preferentially discharged from the outlet after passing through the flow channel.

[0022] The area close to the outlet of the flow channel has a narrower flow channel, so that the outlet water has a certain resistance, so as to force the water in the flow channel to flow into the filtering area first, and when the filter core is blocked, the water can flow out normally from the flow channel.

[0023] The preferred embodiment of the present application also includes a lower shell, and the main body is connected through the lower shell and the blade cover; the lower shell has a water inlet and a water outlet;

[0024] The lower shell has a cavity accommodating the impeller; the water outlet is communicated with the inner part of the main body through the flow channel.

[0025] In order to facilitate the rotation of the impeller and the outlet of the water, the accommodation space and the internal passage are formed through the lower shell, and the water inlet and the water outlet are formed.

[0026] The preferred embodiment of the present application, the inner part of the main body is also provided with a Hall water level sensing area, the Hall water level sensing area is isolated and not communicated with the inner bracket and the flow channel.

[0027] The conventional water dispenser needs electronic components in water to detect low water level, or the process is very complex, which needs perforation and other operations; the present application ingeniously integrates it in the drainage component, the whole component of the water dispenser is less, and only the drainage component is in the water tank, and the detachable mode of the drainage component is also convenient for cleaning.

[0028] The preferred embodiment of the present application, the inner part of the main body is also provided with a Hall water level sensing area, the Hall water level sensing area is isolated and not communicated with the inner bracket and the flow channel, and the Hall area penetrates the main body and the lower shell from top to bottom.

[0029] The main body and the lower shell are two independent components, and the sensing range of the Hall element is increased through the penetration design.

[0030] The present application also relates to a pet water dispenser, and the water storage tank of the water dispenser comprises a magnetic driving drainage device.

[0031] The preferred embodiment of the present application, the backflow port of the water tray is located at the periphery of the drainage device, so that the backflow water adheres to the outside of the drainage device into the water storage tank.

[0032] The water flow backflows along the outer surface of the columnar filter core, avoids the noise generated by the low water level in the water tank, optimizes the noise problem of the water flow of the pet water dispenser, and avoids the disturbance of the water flow sound in daily use.

[0033] In the preferred embodiment of the present application, the water dispenser body is arranged separately from the base, and the water dispenser body is arranged on the base; the driving mechanism inside the base is magnetically attracted to the impeller of the drainage device inside the water tank, and drives the rotation of the impeller.

[0034] The inner water tank can be installed without damage, that is, if a consumer only purchases a single water tank version and has subsequent upgrade needs, the inner water tank can be purchased separately and installed without damage; the base can be replaced without damage, that is, if a consumer purchases a basic function configuration and has subsequent upgrade needs, different functions can be realized by separately purchasing the base for installation without damage, and complete adaptation.

[0035] In the preferred embodiment of the present application, the base comprises a current detection circuit, when the current is low, the motor rotates at a low speed, and the auxiliary impeller is aligned; when the current is high, the motor rotates at a high speed, and the water pumping function is realized.

[0036] The above design solves the problem of slippage, different frequencies, and inability to rotate synchronously caused by the inability of the impeller to be attracted after the motor starts.

[0037] In the preferred embodiment of the present application, the drinking tray is locked and connected between the water dispenser body and the water dispenser body through a lock.

[0038] The outer water tank is provided with safety locks on both sides, which can fix the filter tray and cannot be easily opened, preventing pets from disassembling the machine to cause water overflow, water spilling, and the problem of the water dispenser being unable to normally pump water and work.

[0039] Advantages:

[0040] (1) The present application solves the problem of daily cleaning of pet water dispensers, greatly simplifies the structure of the water pump, and reduces the number of parts that need to be cleaned and the difficulty of cleaning.

[0041] (2) The problem of the pet water dispenser with an electric water pump being soaked in water for a long time is solved, and the risk of electric shock and short circuit is avoided at the root.

[0064] Embodiment One

[0065] Referring to the drawings Figures 1-8 The embodiment discloses a magnetic driving drainage device, which is arranged in a water storage tank of a pet water dispenser (not shown in the figure) and comprises a main body 1 and a fan blade cover 2.

[0066] The top end of the main body 1 is provided with an outflow part 5, and the bottom is detachably connected to the fan blade cover 2 without using fasteners. A plurality of magnet units (not shown in the figure) are arranged on the impeller 6 of the fan blade cover 2. The magnetic force is adsorbed and transmitted through the magnet driving part on the driving mechanism (not shown in the figure) on the base 14 of the water dispenser.

[0067] The cross section of the outflow part 5 is smaller than that of the top of the main body 1, and the outflow part 5 is provided with a necked part 8.

[0068] The inner wall of the main body is further provided with an inner bracket 7, the side wall and the top wall of the inner bracket 7 are provided with flow-through holes 7-1, and at least one group of filter core bags (not shown in the figure) are arranged in the inner bracket 7.

[0069] The inner bracket 7-1 and the inner wall of the main body 1 form a flow channel, and the flow channel is communicated with the inner space of the inner bracket through the flow-through holes.

[0070] The inner bracket 7-1 divides the inner part of the main body 1 into two independent spaces, a first space 9 and a second space 10. The first space 9 and the main body 1 form a flow channel, and the second space 10 forms a filtering area.

[0071] The ''positioning'' here means that the water pump is in contact with the water tank by direct placement without additional fixing means, or the water tank has an indication position for direct placement.

[0072] The assembly adopts magnetic adsorption, and materials that can be penetrated by magnetic force can be used as the water tank material, greatly solving the material limitation and expanding the application scenarios.

[0073] The inner bracket 7 can be a separate component or a unit integrated in the inner cavity of the main body 1, as long as it can divide the inside of the main body into two areas.

[0074] The impeller 6 of the present application is arranged on the fan cover 2 and is not a pump body shell unit, but is detachably connected with the water inlet drainage main body in a non-fastener mode, such as buckle connection, or over sleeve connection, plug connection and the like.

[0075] In this way, the user can easily disassemble the main body and the fan cover 2 for cleaning, and only these two components are in the water tank, so that the water tank is clean and hygienic, and is not easy to hide dirt and is easy to clean.

[0076] The fan cover 2 can be directly adsorbed in the water tank by the driving mechanism on the base to play an auxiliary positioning role, and the user can also take out the fan cover 2 for separate cleaning of the impeller, and more importantly, the material of the water tank is not limited and can be plastic, metal or even a combination of the two, so that the appearance of the water tank can be more liked by the user.

[0077] Compared with the water dispensers on the market, since the connection between the water pump and the water tank has a matching relationship and is not convenient to disassemble and clean, the present application can nest more than two water tanks, for example, the outer layer is a frosted translucent water tank, and the inner layer is a bright metal water tank. The outer water tank constitutes an outer shell, and the inner water tank is used for water storage. At the same time, the inner water tank or the outer water tank can be used alone, as long as the driving force and the adsorption force between the driving mechanism and the impeller disc do not affect the water outlet. Of course, the water tank can also be made of ceramic, glass or stone material.

[0078] The outflow part 5 is smaller than the cross-sectional area of the main body 1, which facilitates the water outlet with pressure and makes it easier to flow out. At the same time, the outflow part has a neck-in part 8 inside to further give the water flow a certain resistance, thereby enhancing the water outlet pressure and making more internal water flow preferentially flow into the filter bin for filtration before flowing out.

[0079] The inner bracket 7 in the main body 1 divides the inside of the main body into two space areas, a flow channel and a filter area, which are communicated, so that even if the filter area is blocked, the water flow is not affected.

[0080] The filter package assembly (not shown in the figure) is arranged inside the drainage device, so that the water dispenser has multiple filtering modes.

[0081] Preferably, the filter package assembly comprises filter materials such as coconut shell activated carbon and ion exchange resin, and is stacked in a three-dimensional multi-layer manner, can adsorb heavy metals, excessive minerals (calcium and magnesium ions), and different colors and odors, and can reduce the probability of algal and larval reproduction and delay the formation of biological membranes (sticky substances).

[0082] In the preferred embodiment of the present application, the upper part of the inner bracket 7 and the inner part of the main body 1 form a flow channel that is narrower than other areas, forming a narrowing part 11, so that most of the water flow preferentially passes through the filter cartridge package and then flows out from the outlet part; when the filter cartridge is blocked, most of the water flow preferentially passes through the flow channel and then flows out from the outlet part.

[0083] The area close to the outlet part of the flow channel has a narrower flow channel, so that the outlet water has a certain resistance, forcing the water in the flow channel to flow into the filtering area first, and when the filter cartridge is blocked, the water can flow out normally from the flow channel.

[0084] After the water flow enters the filter cartridge, it is filtered under the action of the filter material; another area directly reaches the water outlet of the filter cartridge, ensuring that the filtered water can be normally discharged, and preventing the water flow from being able to pass normally after the dirty blockage of the filter material, preventing the water from being unable to work.

[0085] The preferred embodiment of the present application further comprises a lower shell 3, and the main body 1 is connected through the lower shell 3 and the blade cover 2; the lower shell 3 has a water inlet and a water outlet 3-2;

[0086] Further, the water inlet is also provided with biochemical cotton, which is prevented from being separated by the fence 3-1. The biochemical cotton performs secondary filtration on large particles of dirt entering the water tank, allowing the water flow while preventing the impeller from being stuck and affecting work, and preventing the dirt from rising with the water flow and being drunk by the pet.

[0087] The lower shell 3 has an impeller cavity 3-4 accommodating the impeller; and the water outlet 3-2 is in communication with the inside of the main body.

[0088] In order to facilitate the rotation of the impeller 6 and the outlet of water, the lower shell 3 forms a containing space and an internal passage with water inlet and outlet.

[0089] In the preferred embodiment of the present application, the inside of the main body is also provided with a Hall water level sensing area, which is isolated and not in communication with the inner bracket and the flow channel.

[0090] The conventional water dispenser needs electronic components in water to detect low water level, or the process is very complex, needs perforation and other operations; the application ingeniously integrates the same in the drainage component, the whole component of the water dispenser is less, only the drainage component in the water tank, and the detachable mode of the drainage component is convenient for cleaning.

[0091] The Hall induction circuit board is placed in the bottom base 14, the Hall water level sensing area stores the Hall floating ball, can float with the water level in the water tank, and triggers the Hall induction circuit board in the bottom base 14 when being below the lowest water level line, and alarms low water level.

[0092] The shell of the drainage device can be plastic, and is connected with the fan blade cover 2. An internal waterway and a space for storing the Hall floating ball are reserved, and the two parts exist independently and are not connected; the waterway part connects two areas, one of which stores filter materials such as coconut shell activated carbon and ion exchange resin, and is three-dimensionally and multi-layered, can adsorb heavy metals, excessive minerals (calcium and magnesium ions), and different colors and odors, and at the same time, reduces the probability of algae and larva breeding, and delays the formation of biological membranes (sticky substances); after the water flows into the filter element through the water pump, the water is filtered under the action of the filter material; the other area directly reaches the water outlet of the filter element, ensures that the water can be normally discharged after being filtered, and prevents the water from being normally passed after the filter material is blocked by dirt, and prevents the water from being unable to be discharged and work.

[0093] In the preferred embodiment of the application, the main body further comprises a Hall water level sensing area, the Hall water level sensing area is isolated from the inner bracket and the flow channel, and the Hall area penetrates the main body and the lower shell from top to bottom.

[0094] The space for storing the floating ball is connected with the upper and lower parts, so that the floating ball can freely float with the change of the water level, that is, when the water level rises, the floating ball rises with the horizontal surface, when the water level drops, the floating ball drops with the water level, and keeps flush with the horizontal surface at all times, when the water level drops to the lower limit position, the Hall induction is triggered, the atmosphere lamp of the base starts to slowly flicker (1 second flicker 1 time), the low water level alarm is realized, and the consumer is prompted to add water, during the water adding process, when the water level is higher than the lower limit position, the Hall induction disappears, the slow flicker (1 second flicker 1 time) of the atmosphere lamp ends, and the low water level alarm is released.

[0095] The main body and the lower shell are two independent components, and the sensing range of the Hall element is increased through the penetration design.

[0096] The Hall water inlet and outlet 3-5 are arranged at the bottom of the Hall area of the lower shell 3, and the main body is also provided with a flow port at the top of the Hall area, so that the water inlet and outlet are guaranteed through the up-down arrangement, and the Hall floating ball can keep flush with the horizontal line.

[0097] In addition, the drainage device is embedded with the filter core disc of the water dispenser, two protrusions are reserved on the top of the main body 1, and two grooves are reserved on the inner side of the top of the filter core disc, so that even if the assembly is not installed correctly in place, when the filter core disc is installed, the main body can be limited to be correctly returned to the place together with the impeller assembly, and is guided along the grooves to ensure that it is installed to the correct position.

[0098] Specifically, the drainage device is a flat columnar structure as a whole, the bottom is cylindrical, and the top is conical. Figure 1 The general shape is shown.

[0099] Embodiment two

[0100] Referring to Figures 5-8 The application also relates to a pet water dispenser, which comprises a magnetic driving drainage device in a water storage tank.

[0101] The pet water dispenser can be powered or can be installed with a battery or a rechargeable battery.

[0102] The battery version can be configured, and a 5000mAh or 10000mAh rechargeable battery is built-in.

[0103] In a preferred embodiment of the application, the backflow port of the water tray is located on the periphery of the drainage device, so that the backflow water adheres to the outer side of the drainage device and enters the water storage tank.

[0104] The water tray adopts a 360° backflow mode, that is, water can backflow from 360°, which reduces the risk of water overflow compared with the traditional pet water dispenser which only has 1-3 backflow ports; meanwhile, in the filter core disc part, in addition to the conventional four backwater ports, two additional backwater ports are reserved on the higher part of the two sides for backflow.

[0105] Specifically, the filter core disc and the water tray are included, the filter core disc is provided with a filter core groove 19 and a second protrusion 22, biochemical cotton is placed in the filter core groove 19, four first backwater ports 20 are arranged near the outflow part, and two second backwater ports 21 are arranged at the edge of the filter core disc. The backwater ports are all located above the drainage device, and the backflow water backflows along the edge of the drainage device. The second backwater port 21 can avoid the situation that the water tension is too large to backflow.

[0106] The biochemical cotton is placed in the filter core disc, allows water flow while intercepting large-particle dirt (hair, dust, mucus, and small-particle food residues), and prevents most large-particle dirt from entering the water tank and polluting the water tank.

[0107] Preferably, the second protrusion 22 lifts the water tray, and the water tray is smaller than the filter core disc, so that a backflow channel 16 is formed between the two around the area, and 360° backflow is realized.

[0108] The water dispenser comprises a base 14 and a water dispenser body 13; the two are independent separable components;

[0109] The driving mechanism is located in the base 14, and preferably, the driving mechanism is a motor, and a rotating part is arranged on an output shaft of the motor, and a plurality of magnet units are arranged on the rotating part.

[0110] The impeller is provided with four magnets, and the upper part of the power motor rotor is nested with a plastic part (i.e. the rotating part), and the plastic part is provided with four magnets corresponding to the magnets in the impeller; two of the magnets have the same magnetic pole, and the other two magnets have opposite magnetic poles; the magnetic force penetrates the water tank, so that the impeller is prevented from being completely attracted by the magnets above the motor and cannot rotate; and the impeller can be attracted by a certain magnetic force and rotate with the motor.

[0111] Preferably, the components (spray head, water tray) directly contacting the mouth and tongue of the pet during the pet drinking process are made of food-grade 304 stainless steel and food-grade ceramic material, so as to avoid bacterial growth and dirt accumulation, facilitate cleaning, and thus avoid the occurrence of pet skin diseases; at the same time, the inner water tank is made of food-grade 304 stainless steel and food-grade ceramic material, so as to avoid bacterial growth at the source and facilitate cleaning, thereby avoiding the occurrence of pet skin diseases.

[0112] Preferably, the spray head is integrally stamped or formed by high-temperature firing of food-grade 304 stainless steel or food-grade ceramic, and has a smooth and round structure without dead angles, so as to be not easy to accumulate dirt and easy to clean; the water tray is integrally stamped and formed by edge rolling of food-grade 304 stainless steel or formed by high-temperature firing of food-grade ceramic, and has a smooth and round structure without dead angles, so as to be not easy to accumulate dirt and easy to clean; the outer water tank is integrally injection molded by food-grade ABS, and has a smooth and round structure, and the bottom convex part is rounded without dead angles, so as to be not easy to accumulate dirt and easy to clean; the inner water tank is integrally stamped and formed by edge rolling of food-grade 304 stainless steel or formed by high-temperature firing of food-grade ceramic, and has a smooth and round structure, and the bottom convex part is rounded without dead angles, so as to be not easy to accumulate dirt and easy to clean.

[0113] The water flow returns along the outer surface of the column drainage device, so as to avoid noise generated by water flow falling when the water level in the water tank is low, optimize the noise problem of the water flow of the pet water dispenser, and avoid the disturbance of the water flow sound in daily use.

[0114] In the preferred embodiment of the present application, the water dispenser body 13 and the base 14 are separately arranged, and the water dispenser body 13 is arranged on the base 14; the driving mechanism in the base 14 and the impeller of the drainage device in the water tank are magnetically attracted and driven to rotate.

[0115] The inner water tank can be installed without damage, that is, if a consumer only purchases a single water tank version and has subsequent upgrade needs, the inner water tank can be purchased separately and installed without damage; the base can be replaced without damage, that is, if a consumer purchases a basic function configuration and has subsequent upgrade needs, different functions can be realized by separately purchasing a base for installation without damage, and complete adaptation.

[0116] In a preferred embodiment of the application, the base comprises a current detection circuit, when the current is low, the motor rotates at low speed, and the auxiliary impeller is aligned; when the current is high, the motor rotates at high speed, and the water pumping function is realized.

[0117] Whether it is working normally is determined by detecting the current size. If the magnet above the motor in the bottom shell normally attracts the magnet in the impeller, it drives normal rotation, and the load current value is relatively high. If it does not normally attract, it slips, which is equivalent to no-load current, and the value is relatively small. The difference between the load current and the no-load current is safe, and can be realized by current detection, with a very low false alarm probability. Therefore, whether it slips is determined by detecting the current size. If it is detected that it slips, that is, the no-load current is relatively low, the motor will automatically slow down and try to attract the impeller; once it is attracted (although at low speed), it is equivalent to a relatively large load current, and the motor will automatically speed up.

[0118] The above design solves the problems of slipping, different frequencies, and unable to rotate synchronously caused by the impeller failing to attract after the motor starts.

[0119] In a preferred embodiment of the application, the water tray is locked and connected with the water dispenser main body 13 through a lock catch 17.

[0120] The safety lock catch 17 is arranged on both sides of the water dispenser main body 13, can fix the filter core tray and cannot be easily opened, prevents pets from disassembling the machine to cause water overflow, water spilling, and the water dispenser cannot normally pump water and work.

[0121] The water dispenser main body 13 here is an outer water tank, and the main electronic components of the application are integrated on the base 14. The main body only has a water tank, a filter disc, a water tray, and an internal drainage device, which are all non-electric, and the main machine and the base can be designed to be separable, facilitating cleaning of the whole machine. The main machine can be completely flushed and cleaned, which is convenient for users to use.

[0122] The water storage tank also only has a drainage device unit, which is also a non-electric design, and the drainage device is also convenient to disassemble and clean.

[0123] The safety buckle of the outer water tank is preferably made of PP material and is designed in a segmented manner, and the total number of components is two; while being compatible with different water tanks, the PP material can achieve safe locking, and due to the material characteristics, a certain deformation space is reserved to prevent breakage; the connection between the two components adopts a metal rotating shaft, which increases rigidity while rotating flexibly without obstruction; the safety buckle and the water tank connection part also adopt a metal rotating shaft, which increases rigidity while rotating flexibly without obstruction.

[0124] The water dispenser adopts a double-layer water tank design, the outer water tank can be used alone or in combination with the inner water tank, and various combinations of appearance effects can be generated by combining the different colors and process treatments of the two water tanks.

[0125] The structure design of the water tank allows for lossless installation, the edge of the filter disc is designed with a reserved clamping groove on the inner side, when the outer water tank is used alone, the clamping groove can completely fix and tighten the outer water tank to prevent deformation and stable placement; when the outer water tank and the inner water tank are used in combination, the edge can be placed stably, and the structure design realizes compatibility of the two different use modes; the safety buckle of the outer water tank is designed in a segmented manner, and the total number of components is two, the upper component is designed with an interference, so that when the outer water tank is used alone, a certain activity space is left while the outer water tank can be effectively fixed with the filter tray; when the outer water tank and the inner water tank are used in combination, the height difference increases, and the interference design compensates for the activity space, so that the outer water tank can still be effectively fixed with the filter tray, realizing the compatibility of the design; the water pump base is compatible with the outer water tank and the inner water tank, and the bottom of the two water tanks is provided with a designated installation position, which can be seen by the naked eye, and auxiliary positioning; the thickness of the outer water tank and the inner water tank is controlled at the same time, as long as it is ensured that whether the outer water tank is used alone or in combination with the inner water tank, the magnetic force can effectively attract the impeller, realizing the compatibility of the structure;

[0126] The structure design part of the base compatible with the battery version and the basic version: the base structure reserves a battery installation position, the size is designed according to a 50000mAh battery, and there is one on each of the left and right sides, a total of two; when the battery is not needed, the battery accessory is removed, and when the battery is needed, a 5000mAh battery can be selected for single power supply or two 5000mAh batteries can be connected in parallel or series to form a larger battery capacity;

[0127] The base 14 is provided with an atmosphere lamp, the outer water tank is made of transparent material or transparent frosted treatment, the atmosphere lamp is kept on in the plugged state, and can be turned off by pressing the key; at the same time, the atmosphere lamp can make the user have a good visual effect and bring a pleasant mood.

[0128] The base of the water dispenser is also provided with a radar sensing module. When the radar sensing module detects a moving object, water is discharged for 10-30 seconds, and the atmosphere lamp is lit for 3 seconds when the water discharge action is performed, and can be turned off by a button. Through the above settings, electricity can be saved, especially in the battery power supply state.

[0129] Regardless of the plugged-in state or the battery power supply state, the atmosphere lamp also has several control modes: when a moving object is detected, the atmosphere lamp is lit for N seconds; when the power value is lower than the power threshold, the atmosphere lamp flashes at a first speed; when the water level is lower than the water level threshold, the atmosphere lamp flashes at a second speed; when the device is charging, the atmosphere lamp gradually turns off / turns on.

[0130] Specifically, when the device triggers a low power alarm (power ≤ 20%), the atmosphere lamp flashes quickly (1 flash in 0.5 seconds), even in the atmosphere lamp off state, an alarm is given; when the device triggers a low water level alarm (water level is lower than the lower limit value), the atmosphere lamp flashes quickly (1 flash in 1 second), even in the atmosphere lamp off state, an alarm is given; when the device is charging, the atmosphere lamp breathes (gradually turns off / turns on in 1 second), even in the atmosphere lamp off state, a prompt is given.

[0131] The base structure reserves battery mounting positions, the size is designed according to a 50000mAh battery, there are 1 on the left and right sides, a total of 2 are reserved; when it cannot meet the requirement of being plugged in at all times, a 5000mAh battery can be selected for individual power supply or 2 5000mAh batteries can be connected in parallel or series to form a larger battery capacity.

[0132] Preferably, in order to facilitate the positioning of the water storage tank, the top of the base 14 is also provided with a positioning part 18, which can be a protrusion, a groove, or other limiting parts such as columns, points, ribs, walls, etc. Of course, both can be sleeved.
