Description

Technical Field

[0001] This application belongs to the technical field of pet intelligent supplies, and particularly relates to a magnetic drive drainage device and a water dispenser. Background Art

[0002] The existing technology is an automatic pet water dispenser that uses a submersible pump as a power device to transport the stored water in the water tank to the water tray and forms a flowing manner for pets to drink water.

[0003] The electric water pump of the pet water dispenser is immersed in water for a long time, which is prone to risks such as electric leakage and short circuit.

[0004] There are also water dispensers driven by electromagnetic or magnetic force. However, their driving mechanisms are complex and not easy to disassemble, making cleaning inconvenient and prone to dirt accumulation.

[0005] Some water dispenser water pumps have a filtering structure, but there is a problem of filter blockage, resulting in blocked water output. Summary of the Invention

[0006] In view of the above analysis, embodiments of the present invention aim to provide a magnetic drive drainage device and a water dispenser to solve problems such as difficult cleaning, low water output efficiency, affecting energy efficiency, difficult disassembly, and complex structure of existing water dispensers.

[0007] The technical solution provided by the embodiments of this application is realized through the following scheme:

[0008] A magnetic drive drainage device, the drainage device is located in the water storage tank of the pet water dispenser, and it includes a main body and a wind blade cover;

[0009] The top of the main body has an outflow part, and the bottom is detachably connected to the wind blade cover without using fasteners; wherein there is an impeller on the wind blade cover, and a plurality of magnet units are arranged at intervals on the impeller; magnetic adsorption and transmission are realized through a magnet driving part carried on the driving mechanism on the base of the water dispenser.

[0010] The cross-section of the outflow part is smaller than the cross-section of the top of the main body, and the outflow part has a necking part inside;

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

[0012] A flow channel is formed between the inner bracket and the inner wall of the main body, and the flow channel is communicated with the internal space of the inner bracket through the flow-through holes.

[0013] "Located" here means that it is in contact with the water storage tank by direct placement without additional fixing means, or the water storage tank has an indicating position for convenient direct placement thereon. During installation, when the water pump is placed in the specified area, magnetic force automatically adsorbs, and the magnetic force feedback can be felt by hand; even if the installation is not aligned, during the magnetic drive process, the non-operation problem caused by improper installation can be completely avoided through driving adsorption.

[0014] In the present invention, the impeller is arranged on the impeller disc. There is no pump body housing unit, but it is detachably connected to the water diversion main body for the upper water in a non-fastening manner, such as snap connection, or detachable connection methods such as socket connection and plug connection.

[0015] In this way, users can easily disassemble the main body and the impeller disc for cleaning. There are only these two components in the water tank, making the water tank clean and hygienic, not easy to hide dirt, and easy to clean.

[0016] The impeller disc can be directly adsorbed in the water storage tank through the driving mechanism on the base to play an auxiliary positioning role, and it is also convenient for users to take out the impeller disc for separate cleaning of the impeller. More importantly, the material of the water tank is not limited, and it can be plastic, metal, or even a combination of both, making the appearance of the water tank more liked by users.

[0017] 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 for disassembly and cleaning, in the present invention, two or more water tanks can be nested with each other. For example, the outer layer is a frosted translucent water tank, and the inner layer is a shiny metal water tank. The outer water tank forms the outer shell, and the inner water tank is used for storing water. At the same time, the inner water tank or the outer water tank can be used alone as long as the driving force and adsorption force between the driving mechanism and the impeller disc do not affect the water output. Of course, the water tank can also be made of ceramic, glass, or stone materials.

[0018] The cross-sectional area of the water outlet part is smaller than that of the main body, which is convenient for the water to have pressure and is easier to flow out. At the same time, the inner part of the water outlet part has a constriction part to further give a certain resistance to the water flow. While enhancing the water outlet pressure, more internal water flow preferentially flows into the filter chamber for filtration and then flows out.

[0019] The inner bracket inside the main body divides the inside of the main body into two space areas, the flow channel and the filtration area, which are connected to each other. Thus, even when the filtration area is blocked, it does not affect the outflow of water.

[0020] The filter bag assembly is arranged inside the water diversion device, making the water dispenser have multiple filtration methods.

[0021] In a preferred embodiment of the present invention, a flow channel narrower than those in other areas is formed between the upper part of the inner bracket and the interior of the main body, so that most of the water flow preferentially passes through the filter cartridge pack and then flows out from the water outlet part; when the filter cartridge pack is blocked, most of the water flow preferentially passes through the flow channel and then flows out from the water outlet part.

[0022] The area of the flow channel close to the outflow part has a narrower flow channel, which causes a certain obstruction to the outflowing water, so as to force the water in the flow channel to first flow into the filtration area, and when the filter element is blocked, it can flow out normally from the flow channel.

[0023] In a preferred embodiment of the present invention, it further includes a lower housing, and the main body is connected to the blower cover through the lower housing; the lower housing has a water inlet and a water outlet;

[0024] The lower housing has a cavity for accommodating the impeller; the water outlet is communicated with the interior of the main body.

[0025] In order to facilitate the rotation and water outflow of the impeller, a receiving space and an internal channel are formed through the lower housing for water inlet and outlet.

[0026] In a preferred embodiment of the present invention, a Hall water level sensing area is further provided inside the main body, and the Hall water level sensing area is isolated and not communicated with the inner bracket and the flow channel.

[0027] Conventional water dispensers all require electronic components to be in water to detect the low water level, or the process is very complicated and requires operations such as perforation; the present invention cleverly integrates it into the drainage component. The overall components of the water dispenser are few, and there is only the drainage component in the water tank. At the same time, the detachable method of the drainage component is convenient for cleaning.

[0028] In a preferred embodiment of the present invention, a Hall water level sensing area is further provided inside the main body, and the Hall water level sensing area is isolated and not communicated with the inner bracket and the flow channel. The Hall area penetrates through the main body and the lower housing from top to bottom.

[0029] The main body and the lower housing are two independent components, and the through design increases the sensing range of the Hall element.

[0030] The present invention also relates to a pet water dispenser, and a magnetic drive drainage device is included in the water storage tank of the water dispenser.

[0031] In a preferred embodiment of the present invention, the return port of the drinking tray is located around the drainage device, so that the returned water adheres to the outside of the drainage device and returns to the water storage tank.

[0032] The water flow returns along the outer surface of the columnar filter element, avoiding the noise generated by the water flow dropping when the water level in the water tank is low, optimizing the noise problem of the water flow of the pet water dispenser, and avoiding the disturbance of the water flow sound during daily use.

[0033] In a preferred embodiment of the present invention, the main body of the water dispenser is separately provided from the base, and the main body of the water dispenser is located on the base; a driving mechanism inside the base generates magnetic adsorption with an impeller of a drainage device inside the water storage tank and drives the impeller to rotate.

[0034] The inner water tank can be installed without damage. That is, if consumers only purchase the single-tank version and have an upgrade requirement later, they can purchase the inner water tank separately and install it without damage; the base can be replaced without damage. That is, if consumers purchase the configuration with basic functions and have an upgrade requirement later, they can achieve different functions by purchasing the base separately, install it without damage, and it is fully compatible.

[0035] In a preferred embodiment of the present invention, the base includes a current detection circuit. When the current is below the low threshold, the motor rotates slowly to assist the impeller in alignment; when the current is above the high threshold, the motor rotates at high speed to achieve the water pumping function.

[0036] The above design solves the problems of slipping, different frequencies, and inability to rotate synchronously caused by the impeller not being adsorbed after the motor starts.

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

[0038] Safety lock catches are provided on both sides of the outer water tank, which can fix the filter element tray and prevent it from being easily opened, preventing problems such as water overflow, water spillage, and the water dispenser being unable to pump water and work properly caused by pets disassembling the machine.

[0039] Beneficial effects:

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

[0041] (2) Solves the problem of the charged water pump of the pet water dispenser being immersed in water for a long time, and fundamentally avoids risks such as electric leakage and short circuit.

[0064] Embodiment 1

[0065] See the appendix Figure 1-8 , the embodiment discloses a magnetic-driven drainage device, which is located in the water storage tank of a pet water dispenser (not shown in the figure), and includes a main body 1 and a fan cover 2;

[0066] The top end of the main body 1 has an outflow part 5, and the bottom is detachably connected to the fan cover 2 without using fasteners; wherein a impeller 6 is provided on the fan cover 2, and a plurality of magnet units (not shown in the figure) are spacedly arranged on the impeller 6; magnetic adsorption and transmission are realized by means of a magnet driving member carried on a driving mechanism (not shown in the figure) on the water dispenser base 14;

[0067] The cross-section of the outflow part 5 is smaller than the cross-section of the top of the main body 1, and a constricted part 8 is provided in the outflow part 5;

[0068] An inner bracket 7 is further provided in the main body, and through holes 7-1 are provided on the side wall and the top wall of the inner bracket 7, and at least one group of filter element packages (not shown in the figure) are provided inside;

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

[0070] The inner bracket 7-1 divides the interior of the main body 1 into two independent spaces, a first space 9 and a second space 10. A flow channel is formed between the first space 9 and the main body 1, and the second space 10 forms a filtration area.

[0071] "Located here" means that it is in contact with the water storage tank through direct placement without additional fixing means, or the water storage tank has an indicating position for convenient direct placement thereon. During installation, when the water pump is placed in the specified area, magnetic force is automatically adsorbed and the magnetic force feedback can be felt by hand; even if the installation is not aligned, during the magnetic drive process, the problem of non-operation caused by improper installation can be completely avoided through driving adsorption.

[0072] The components adopt magnetic adsorption, and any material through which magnetic force can penetrate can be used as the water tank material, greatly solving the limitation of materials and expanding the application scenarios.

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

[0074] In the present invention, the impeller 6 is provided on the impeller disc 2. There is no pump body housing unit, but it is detachably connected to the water inlet diversion main body directly in a non-fastening manner, such as snap connection, or detachable connection methods such as socket connection and plug connection.

[0075] In this way, users can easily disassemble the main body and the impeller disc 2 for cleaning. There are only these two components in the water tank, making the water tank clean and hygienic, not easy to hide dirt and easy to clean.

[0076] The impeller disc 2 can be directly adsorbed in the water storage tank through the driving mechanism on the base to play an auxiliary positioning role, and it is also convenient for users to take out the impeller disc 2 for separate cleaning of the impeller. More importantly, the material of the water tank is not limited, and it can be plastic, metal, or even a combination of both, making the appearance of the water tank more liked by users.

[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 for disassembly and cleaning, in the present invention, two or more water tanks can be nested with each other. For example, the outer layer is a frosted translucent water tank, and the inner layer is a shiny metal water tank. The outer water tank forms the outer shell, and the inner water tank is used for storing water. At the same time, the inner water tank or the outer water tank can be used alone as long as the driving force and adsorption force between the driving mechanism and the impeller disc do not affect the water output. Of course, the water tank can also be made of ceramic, glass, or stone materials.

[0078] The cross-sectional area of the outflow part 5 is smaller than that of the main body 1, which is convenient for the water to have pressure and flow out more easily. At the same time, the inner part of the outflow part has a constriction part 8 to further give a certain resistance to the water flow. While enhancing the water output pressure, more internal water flow preferentially flows into the filter chamber for filtration and then flows out.

[0079] The inner bracket 7 inside the main body 1 divides the inside of the main body into two space areas, the flow channel and the filtration area, which are connected. Thus, even when the filtration area is blocked, it does not affect the outflow of water.

[0080] A filter pack assembly (not shown in the figure) is provided inside the drainage device, enabling the water dispenser to have multiple filtration methods.

[0081] Preferably, the filter pack assembly includes filtration materials such as coconut shell activated carbon and ion exchange resin, which are stacked in a three-dimensional multi-layer manner, capable of adsorbing heavy metals, excessive minerals (calcium and magnesium ions), abnormal colors and odors; at the same time, reducing the probability of algae and larva reproduction and delaying the formation of biofilm (sticky substances).

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

[0083] The area of the flow channel close to the outflow part has a narrower flow channel, causing a certain obstruction to the outflowing water, forcing the water in the flow channel to first flow into the filtration area, and when the filter element is blocked, it can flow out normally from the flow channel.

[0084] After the water flow enters the filter element, it is filtered under the action of the filter material; another area directly reaches the water outlet of the filter element, ensuring that the water flow can be discharged normally after filtration, and preventing the water flow from passing through normally when the filter material is blocked by dirt, preventing the inability to discharge water and the inability to work.

[0085] In a preferred embodiment of the present invention, it further includes a lower housing 3, and the main body 1 is connected to the fan cover 2 through the lower housing 3; the lower housing 3 has a water inlet and a water outlet 3-2;

[0086] Furthermore, a biochemical cotton is provided at the water inlet, and it is prevented from detaching by a fence 3-1. The biochemical cotton performs secondary filtration on the large-particle dirt entering the water tank, allowing the water flow to pass through while preventing the impeller from being stuck and affecting the operation, and preventing the dirt from rising with the water flow and being drunk by pets.

[0087] The lower housing 3 has an impeller chamber 3-4 for accommodating the impeller; the water outlet 3 is communicated with the inside of the main body.

[0088] To facilitate the rotation and water discharge of the impeller 6, a receiving space and an internal channel are formed through the lower housing 2 for water inlet and outlet.

[0089] In a preferred embodiment of the present invention, a Hall water level sensing area is further provided inside the main body, and the Hall water level sensing area is isolated and not communicated with the inner bracket and the flow channel.

[0090] Conventional water dispensers require electronic components to be in the water to detect low water levels, or the process is very complicated and requires operations such as punching. The present invention cleverly integrates them into the drainage component. The water dispenser has fewer overall components, and only the drainage component is in the water tank. At the same time, the drainage component is detachable and easy to clean.

[0091] The Hall sensor circuit board is placed inside the base 14, and the Hall water level sensing area stores the Hall float, which can float with the water level in the water tank. When it is lower than the lowest water level line, it triggers the Hall sensor circuit board in the base 14 to alarm the low water level.

[0092] The outer shell of the drainage device can be plastic and connected to the fan blade disc 2. A waterway and a space for storing the Hall float are reserved inside. These 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, which are stacked in three-dimensional multi-layers to absorb heavy metals, excessive minerals (calcium and magnesium ions), and foreign colors and odors; at the same time, it reduces the probability of algae and larvae reproduction and delays the formation of biomass film (sticky substances); after the water flows through the water pump and enters the filter element, it is filtered under the action of the filter material; the other area directly reaches the water outlet of the filter element to ensure that the water flow can be discharged normally after filtration, and prevent the water flow from passing normally after the filter material is blocked by dirt, so as to prevent the water from being unable to discharge and unable to work.

[0093] In a preferred embodiment of the present invention, a Hall water level sensing area is further provided inside the main body, the Hall water level sensing area is isolated from the inner bracket and the flow channel and is not connected to each other, and the Hall area passes through the main body and the lower shell from top to bottom.

[0094] The space for storing the float is connected up and down, which ensures that the float can float freely with the changes in water level. That is, when the water level rises, the float rises with the horizontal plane; when the water level drops, the float drops with the water level line and keeps it level with the horizontal plane at all times; when the water level drops to the lower limit, the Hall sensor is triggered, and the ambient light on the base starts to flash slowly (once per second), realizing a low water level alarm to prompt consumers to add water; during the water adding process, as the water level line rises, when the water level is higher than the lower limit, the Hall sensor disappears, the ambient light stops flashing slowly (once per second), and the low water level alarm is released.

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

[0096] The bottom of the lower shell 3 located in the Hall area is provided with Hall water inlet and outlet 3-5, and the top of the main body located in the Hall area is also provided with a flow port. The up and down settings can ensure the inlet and outlet of water, so that the Hall float can be consistent with the horizontal line.

[0097] In addition, the drainage device is fitted into the filter element tray of the water dispenser. There are 2 protrusions reserved at the top of the main body 1, and 2 grooves are reserved on the inner side of the top of the filter element tray. In this way, even if the components are not installed correctly in place, when installing the filter element tray, it can limit the correct positioning of the main body together with the impeller assembly, and guide it along the grooves to ensure installation in the correct position.

[0098] Specifically, the overall shape of the drainage device is a flat columnar structure, with a cylindrical bottom and a conical top, as shown in Figure 1 which shows the general outer shape.

[0099] Embodiment 2

[0100] See Figure 5-8 , the present invention also relates to a pet water dispenser, and a magnetically driven drainage device is included in the water storage tank of the water dispenser.

[0101] The pet water dispenser can work by plugging in, or can be installed with batteries, or a rechargeable setting;

[0102] There is a configurable battery version with a built-in rechargeable battery of 5000 mAh or 10000 mAh.

[0103] In a preferred embodiment of the present invention, the return port of the drinking water tray is located around the drainage device, so that the returned water fits along the outside of the drainage device into the water storage tank.

[0104] The water tray adopts a four-sided return method, that is, the water can return from 360°. Compared with the design of traditional pet water dispensers that only retain 1-3 return ports, the risk of water overflow is reduced; at the same time, in the filter element tray part, in addition to the conventional 4 reserved water return ports, 2 additional water return ports are reserved at higher positions on both sides for water return.

[0105] Specifically, it includes a filter element tray and a drinking water tray. The filter tray is provided with a filter element slot 19 and a second protrusion 22. A biochemical cotton is placed in the filter element slot 19. There are 4 first water return ports 20 arranged near the outflow part, and 2 second water return ports 21 arranged at the edge position of the filter element tray. The water return ports are all located above the drainage device, and the returned water flows back along the edge of the drainage device. The setting of the second water return port 21 can avoid the situation where the water tension is too large and the water cannot return.

[0106] The biochemical cotton is placed in the filter element tray. While allowing water to pass through, it intercepts large particle dirt (hair, dust, mucus, small particle food residues), preventing most of the large particle dirt from entering the water tank and polluting the water tank.

[0107] Preferably, the second protrusion 22 jacks up the drinking water tray, and the drinking water tray is smaller than the filter element tray, so that a return channel 16 is formed in the surrounding area between the two to achieve 360° return.

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

[0109] The driving mechanism is located inside the base 14. Preferably, the driving mechanism is a motor. A rotating part is provided on the output shaft of the motor, and a plurality of magnet units are provided on the rotating part.

[0110] Among them, the impeller is built-in with 4 magnets. A plastic part (i.e., the rotating part) is nested above the rotor of the power motor. The plastic part is built-in with 4 magnets, corresponding to the magnets inside the impeller; 2 of the magnets have the same magnetic poles, and the other 2 magnets have opposite magnetic poles. The magnetic force penetrates the water tank, which can prevent the impeller from being completely attracted and stuck to the magnet above the motor, resulting in inability to rotate; and there can be a certain magnetic force for adsorption, and it rotates as the motor rotates.

[0111] Preferably, during the pet's drinking process, the components (spray head, water tray) that are in direct contact with the pet's mouth and tongue are made of food-grade 304 stainless steel and food-grade ceramic materials, which can avoid the growth of bacteria and the accumulation of dirt, and are easy to clean, so as to 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 materials, which can avoid the growth of bacteria at the source and is easy to clean, thus avoiding the occurrence of pet skin diseases;

[0112] Preferably, the spray head is formed by integrally stamping food-grade 304 stainless steel or by high-temperature firing of food-grade ceramic. The structure is smooth and round without dead corners, not easy to accumulate dirt and easy to clean by water washing; the water tray is formed by integrally stamping + curling of food-grade 304 stainless steel or by high-temperature firing of food-grade ceramic. The structure is smooth and round without dead corners, not easy to accumulate dirt and easy to clean by water washing; the outer water tank is formed by integrally injection molding food-grade ABS. The structure is smooth and round, and the raised part at the bottom is rounded, without dead corners, not easy to accumulate dirt and easy to clean by water washing; the inner water tank is formed by integrally stamping + curling of food-grade 304 stainless steel or by high-temperature firing of food-grade ceramic. The structure is smooth and round, and the raised part at the bottom is rounded according to the fillet, without dead corners, not easy to accumulate dirt and easy to wash by water.

[0113] The water flow returns along the outer surface of the column drainage device, avoiding the noise generated by the water flow dropping when the water level in the water tank is low, optimizing the noise problem of the water flow of the pet water dispenser, and avoiding the disturbance of the water flow sound during daily use.

[0114] In the preferred embodiment of the present invention, the water dispenser main body 13 is separately provided from the base 14, and the water dispenser main body 13 is located on the base 14; the driving mechanism inside the base 14 generates magnetic adsorption with the impeller of the drainage device inside the water storage tank and drives the impeller to rotate.

[0115] The inner water tank can be installed without damage. That is, if consumers only purchase the single water tank version and have an upgrade requirement later, they can purchase the inner water tank separately and install it without damage; the base can be replaced without damage. That is, if consumers purchase the configuration with basic functions and have an upgrade requirement later, they can achieve different functions by purchasing the base separately, install it without damage, and it is fully compatible.

[0116] In a preferred embodiment of the present invention, the base includes a current detection circuit. When the current is below the low threshold, the motor rotates at a low speed to assist the impeller in aligning; when the current is above the high threshold, the motor rotates at a high speed to achieve the water pumping function.

[0117] By detecting the magnitude of the current to determine whether it is working properly. For the magnet above the motor in the bottom case, if it normally adsorbs the magnet in the impeller and drives it to rotate normally, the load current value will be relatively high. If it does not adsorb normally and slips, it is equivalent to no-load current and will be relatively small. The difference between the load current and the no-load current is safe and can be achieved through current detection, and the false alarm probability is very low. Therefore, it is by detecting the magnitude of this current to determine whether there is slippage. If slippage is detected, that is, the no-load current is relatively low, the motor will automatically reduce its speed and try to adsorb the impeller; once adsorbed (although at a low speed), which is equivalent to a relatively large load current, the motor will automatically increase its speed.

[0118] The above design solves the problems of slippage, different frequencies, and inability to rotate synchronously caused by the impeller not being adsorbed after the motor starts.

[0119] In a preferred embodiment of the present invention, the drinking tray is locked and connected to the water dispenser main body 13 through a lock 17.

[0120] Safety locks 17 are provided on both sides of the water dispenser main body 13, which can fix the filter element tray and prevent it from being easily opened, thus preventing problems such as water overflow, water spillage, and the water dispenser being unable to pump water and work properly caused by pets disassembling the machine.

[0121] Here, the water dispenser main body 13 is the outer water tank. The main electronic components of the present invention are integrated on the base 14. The main body only has a water tank, a filter tray, a drinking tray, and an internal drainage device, all of which are non-electrified. Moreover, the main machine and the base are designed to be separable, which is convenient for cleaning the whole machine. The main machine can be flushed with water as a whole, which is convenient for users to use.

[0122] There is also only one unit of the drainage device in the storage water tank, which is also designed to be non-electrified. The drainage device is also convenient for disassembly and cleaning.

[0123] Preferably, the safety buckle of the outer water tank is made of PP material and is designed in sections, with a total of 2 components. While being compatible with different water tanks, the PP material can achieve safe locking and also has a certain deformation space due to its material properties to prevent breakage. The connection between the 2 components uses a metal rotating shaft, which increases rigidity while allowing for flexible rotation without obstruction. The connection part between the safety lock and the water tank also uses a metal rotating shaft, which increases rigidity while allowing for flexible rotation without obstruction.

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

[0125] The structural design for the non-destructive installation of the water tank: The edge of the filter element tray is designed with a card slot reserved on the inner side. When the outer water tank is used alone, the card slot can completely fix and tighten the outer water tank to prevent the outer water tank from deforming and place it stably. When the outer water tank and the inner water tank are used in combination, the edge can be placed stably, and the structural design realizes the compatibility of the two different usage methods. The safety buckle of the outer water tank is designed in sections, with a total of 2 components. The upper component has an interference fit design. In this way, when the outer water tank is used alone, while leaving a certain amount of movement space, it can effectively fix the outer water tank and the filter element tray. When the outer water tank and the inner water tank are used in combination, the height difference increases, and the interference fit design makes up for the movement space and can still effectively fix the outer water tank and the filter element tray to achieve the compatibility of the design. The water pump base is compatible with the outer water tank and the inner water tank. Installation designated positions are set at the bottoms of both water tanks, which are visible to the naked eye for auxiliary positioning. At the same time, the thicknesses of the outer water tank and the inner water tank are controlled to ensure that whether the outer water tank is used alone or in combination with the inner water tank, the magnetic force can effectively adsorb the impeller to achieve the compatibility of the structure.

[0126] The structural design part of the base compatible with the battery version and the basic version: The base structure reserves battery installation positions, which are designed according to a 50000mAh battery, with 1 on each of the left and right sides, for a total of 2 reserved. When the battery is not needed, the battery accessories can be removed. When the battery is needed, the 5000mAh battery can be selected for single power supply or 2 5000mAh batteries can be connected in parallel or in series to supply power to form a larger battery capacity.

[0127] An ambient light is provided on the base 14. The outer water tank is made of a transparent material or undergoes a transparent frosted treatment. The ambient light remains constantly on in the plugged-in state and can be turned off by pressing a button. At the same time, the ambient light gives users a good visual experience and brings a pleasant mood.

[0128] There is also a radar sensing module installed inside the water dispenser base. After the radar sensing module detects a moving object, water is discharged for 10 - 30 seconds. When the water discharge action is executed, the ambient light is lit for 3 seconds and can be turned off by pressing a button; through the above settings, power can be saved, especially in the battery-powered state.

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

[0130] Specifically, when the device triggers a low battery alarm (battery level ≤ 20%), the ambient light flashes quickly (flashing once every 0.5 seconds), and even when the ambient light is in the off state, an alarm is given; when the device triggers a low water level alarm (water level lower than the lower limit value), the ambient light flashes quickly (flashing once every 1 second), and even when the ambient light is in the off state, an alarm is given; when the device is charging, the ambient light flashes in a breathing pattern (gradually turning off / on within 1 second), and even when the ambient light is in the off state, a reminder is given.

[0131] The base structure reserves battery installation positions. The size is designed according to a 50000mAh battery, with 1 on each of the left and right sides, for a total of 2 reserved; when it is not possible to be plugged in at all times during use, 5000mAh batteries can be selected to be powered separately or two 5000mAh batteries can be connected in parallel or in series to form a larger battery capacity.

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

[0133] The above-described specific implementation manners further elaborate on the purpose, technical solutions, and beneficial effects of the present application. It should be understood that the above is only the specific implementation manners of the present application and is not used to limit the protection scope of the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
