Description

Technical Field

[0001] This application belongs to the field of pet smart product technology, specifically relating to drainage components and pet water fountains. Background Technology

[0002] Existing technology includes automatic pet water fountains that use a submersible pump as a power source to transport water stored in the tank to the water dish, creating a flow for pets to drink.

[0003] Pet water fountains with electric water pumps are prone to risks such as electric leakage and short circuits when they are submerged in water for extended periods.

[0004] There are also water dispensers that are driven by electromagnetic or magnetic forces, but their drive mechanisms are complex and difficult to disassemble, making cleaning inconvenient and prone to accumulating dirt and grime.

[0005] Some water dispensers have a filter structure in their water pumps, but the filter can become clogged, causing water flow to be obstructed. Utility Model Content

[0006] Based on the above analysis, the present invention aims to provide a flow-guiding component and a pet water fountain to solve the problems of existing water fountains, such as difficulty in cleaning, low water output efficiency, impact on energy efficiency, difficulty in disassembly, and complex structure.

[0007] The technical solution provided in this application is achieved through the following approach:

[0008] A flow-guiding component is installed in the water tank of a pet water fountain;

[0009] The main body of the diversion component has an outlet at the top and an impeller at the bottom. It rotates through indirect transmission with the drive mechanism on the water dispenser base to draw water out of the water tank.

[0010] The main body is also provided with an inner bracket, and the side wall and top wall of the inner bracket are provided with flow holes, and at least one set of filter cartridges are provided inside.

[0011] A flow channel is formed between the inner bracket and the inner wall of the main body, and the flow channel is connected to the internal space of the inner bracket through the flow hole.

[0012] The drive mechanism of this utility model is located on the base and is indirectly driven. The water tank contains only a non-electrically charged diversion component, which is not fixedly connected to the water tank, making it easy to clean and eliminating the risk of leakage or short circuit.

[0013] Compared to commercially available water dispensers, which are inconvenient to disassemble and clean due to the connection between the water pump and the water tank, this invention allows for nested water tanks. For example, the outer tank can be a frosted semi-transparent tank, while the inner tank is a bright metal tank. The outer tank forms the outer shell, and the inner tank stores water. Alternatively, either the inner or outer tank can be used independently, as long as the driving force and suction between the drive mechanism and the impeller do not affect water output. The water tank can also be made of ceramic, glass, or stone.

[0014] The internal bracket inside the main body divides the interior into two spatial areas: the flow channel and the filtration zone. The two are connected, so that even if the filtration zone is blocked, the water flow will not be affected.

[0015] The internal filter assembly of the flow diversion component enables the water dispenser to have multiple filtration methods.

[0016] In a preferred embodiment of this utility model, the upper part of the inner bracket forms a flow channel that is narrower than the flow channels in other areas, so that most of the water flow preferentially passes through the filter cartridge and then flows out from the water outlet; and when the filter cartridge is clogged, most of the water flow preferentially passes through the flow channel and then flows out from the water outlet.

[0017] The area near the outlet has a narrower flow channel, which obstructs the outflow and forces the water in the channel to flow into the filtration area first, while the filter cartridge can flow out normally when it is clogged.

[0018] In a preferred embodiment of this utility model, a lower housing is also included, and the main body is connected to the fan blade cover via the lower housing; the lower housing has a water inlet and a water outlet;

[0019] The lower housing has a cavity for accommodating the impeller; the outlet is connected to the interior of the main body.

[0020] To facilitate the rotation of the impeller and the discharge of water, the lower casing forms a receiving space and an internal channel for water inlet and outlet.

[0021] In a preferred embodiment of this utility model, a Hall level sensing area is further provided inside the main body, and the Hall level sensing area is isolated from and not connected to the inner bracket and the flow channel.

[0022] Conventional water dispensers require electronic components to be submerged in water to detect low water levels, or their manufacturing process is complex and requires perforation. This invention cleverly integrates these components into the flow-guiding part, resulting in fewer overall parts in the water dispenser. The water tank contains only the flow-guiding part, and the detachable design of the flow-guiding part facilitates cleaning.

[0023] In a preferred embodiment of this utility model, a Hall level sensing area is further provided inside the main body. The Hall level sensing area is isolated from and not connected to the inner bracket and the flow channel. The Hall area extends from top to bottom through the main body and the lower shell.

[0024] The main body and the lower housing are two separate components, and the through-type design increases the sensing range of the Hall element.

[0025] A preferred embodiment of this utility model further includes a fan blade cover, on which the impeller is disposed; a plurality of magnet units are spaced apart on the impeller; the rotating component on the corresponding drive mechanism has a plurality of magnet units, and the two are attracted and rotated by magnetic attraction.

[0026] The impeller disc can be directly attached to the water tank via the drive mechanism on the base, serving as an auxiliary positioning tool. Users can also easily remove the impeller disc for individual cleaning of the impeller. More importantly, the material of the water tank is not limited; it can be plastic, metal, or even a combination of both, making the appearance of the water tank more appealing to users.

[0027] This utility model also relates to a pet water dispenser, wherein the water tank of the water dispenser includes a magnetically driven flow guiding component.

[0028] In a preferred embodiment of this utility model, the return port of the drinking tray is located around the periphery of the diversion component, so that the returned water adheres to the outside of the diversion component and flows into the water storage tank.

[0029] The water flows back along the outer surface of the columnar filter element, avoiding the noise caused by the water falling when the water level in the tank is low. This optimizes the noise problem of the water flow in the pet water fountain and avoids the disturbance of water flow sound during daily use.

[0030] In a preferred embodiment of this utility model, the water dispenser body and the base are separately arranged, with the water dispenser body sitting on the base; the drive mechanism inside the base magnetically attracts the impeller of the diversion component inside the water storage tank and drives the impeller to rotate.

[0031] The inner water tank can be installed without damage. If a consumer only purchases the single water tank version and has upgrade needs later, they can purchase the inner water tank separately and install it without damage. The base can be replaced without damage. If a consumer purchases the basic configuration and has upgrade needs later, they can purchase the base separately to achieve different functions. It can be installed without damage and is fully compatible.

[0032] In a preferred embodiment of this utility model, the water tray and the main body of the water dispenser are locked together by a latch.

[0033] Safety locks are installed on both sides of the outer water tank to secure the filter tray and prevent it from being easily opened, thus preventing problems such as overflow, spillage, and the water dispenser malfunctioning due to pets disassembling the machine.

[0034] Beneficial effects:

[0035] (1) It solves the problem of daily cleaning difficulties of pet water fountains, greatly simplifies the structure of the water pump, reduces the number of parts that need to be cleaned and the difficulty of cleaning.

[0036] (2) Solve the problem of pet water fountain pumps being submerged in water for a long time, thus avoiding the risk of leakage and short circuit at the source.

[0059] Example 1

[0060] See appendix Figure 1-8 The embodiment discloses a drainage component, which is disposed in the water tank of a pet water fountain (not shown in the figure).

[0061] The main body 1 of the diversion component has an outlet 5 at the top and an impeller 6 at the bottom, which is indirectly driven by the drive mechanism (not shown in the figure) on the water dispenser base 14.

[0062] The main body is also provided with an inner bracket 7, and the inner bracket 7 has flow holes 7-1 on its side wall and top wall, and at least one set of filter cartridges (not shown in the figure) is provided inside.

[0063] 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 connected to the internal space of the inner bracket through the flow hole.

[0064] Preferably, indirect transmission can be magnetic transmission, hydraulic coupling, etc.

[0065] The inner bracket 7-1 divides the interior of the main body 1 into two independent spaces, the first space 9 and the second space 10. The first space 9 forms a flow channel with the main body 1, and the second space 10 forms a filtration area.

[0066] Preferably, the diversion component is located in the water storage tank and also includes a fan cover 2, on which the impeller is disposed; multiple magnet units are spaced apart on the impeller 6; the rotating part of the corresponding drive mechanism has multiple magnet units, and the two are attracted and rotated by magnetic attraction.

[0067] The airflow assembly and the fan cover 2 are detachably connected using non-fastener methods, such as plug-in or socket connections.

[0068] Here, "placement" refers to direct placement without additional securing means to the water tank, or placement on a designated area with an indicator for easy placement. During installation, the water pump automatically attaches magnetically when placed within the designated area, and the magnetic force can be felt by hand. Even if not properly aligned, the magnetic drive ensures that misalignment will prevent malfunctions.

[0069] The components are magnetically adsorbed, and any material that can be penetrated by magnets can be used as the water tank material, which greatly solves the limitations of materials and expands the application scenarios.

[0070] 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 interior of the main body into two areas.

[0071] Preferably, the cross-section of the outflow portion 5 is smaller than the cross-section of the top of the main body 1, and the outflow portion 5 has a constriction neck 8 inside.

[0072] The outlet section has a smaller cross-sectional area than the main body, which makes it easier to pressurize the water and make it easier to discharge water. At the same time, the outlet section has a constriction inside, which further increases the resistance to the water flow. This increases the water pressure and allows more internal water to flow into the filter chamber for filtration before flowing out.

[0073] The impeller 6 of this utility model is mounted on the impeller disk 2 and does not have a pump body housing unit. Instead, it is directly and detachably connected to the water intake body in a non-fastener manner, such as by snap-fit, or by easy disassembly methods such as sleeve or plug-in.

[0074] This allows users to easily disassemble the main body and impeller 2 for cleaning. The water tank contains only these two parts, making the water tank clean and hygienic, less prone to dirt accumulation, and easy to clean.

[0075] The impeller disk 2 can be directly attached to the water tank through the drive mechanism on the base to play an auxiliary positioning role. Users can also easily remove the impeller disk 2 for separate cleaning of the impeller. More importantly, the material of the water tank is not limited. It can be plastic, metal, or even a combination of both, so that the appearance of the water tank can be more appealing to users.

[0076] Compared to commercially available water dispensers, which are inconvenient to disassemble and clean due to the connection between the water pump and the water tank, this invention allows for nested water tanks. For example, the outer tank can be a frosted semi-transparent tank, while the inner tank is a bright metal tank. The outer tank forms the outer shell, and the inner tank stores water. Alternatively, either the inner or outer tank can be used independently, as long as the driving force and suction between the drive mechanism and the impeller do not affect water output. The water tank can also be made of ceramic, glass, or stone.

[0077] The outlet section 5 has a smaller cross-sectional area than the main body 1, which makes it easier to pressurize the water and make it easier to discharge water. At the same time, the outlet section has a constriction neck 8 to further increase the resistance to the water flow. While increasing the water pressure, it also allows more internal water to flow into the filter chamber for filtration before flowing out.

[0078] The internal bracket 7 inside the main body 1 divides the main body into two spatial areas: the flow channel and the filtration zone. The two are connected, so that even if the filtration zone is blocked, the water flow will not be affected.

[0079] The water dispenser has multiple filtration methods because the internal filter pack (not shown in the figure) is installed in the flow diversion component.

[0080] Preferably, the filter bag assembly includes filter materials such as coconut shell activated carbon and ion exchange resin, stacked in a three-dimensional, multi-layered manner, which can adsorb heavy metals, excess minerals (calcium and magnesium ions), and off-colors and odors; at the same time, it reduces the probability of algae and larval reproduction and delays the formation of biofilm (sticky substances).

[0081] In a preferred embodiment of this utility model, the upper part of the inner bracket 7 forms a narrower flow channel than other areas between it and the interior of the main body 1, forming a narrowing portion 11, so that most of the water flow preferentially passes through the filter cartridge and flows out from the outlet; and when the filter cartridge is clogged, most of the water flow preferentially passes through the flow channel and flows out from the outlet.

[0082] The area near the outlet has a narrower flow channel, which obstructs the outflow and forces the water in the channel to flow into the filtration area first, while the filter cartridge can flow out normally when it is clogged.

[0083] After the water flows into the filter element, it is filtered by the filter media; another area leads directly to the outlet of the filter element to ensure that the filtered water can be discharged normally and to prevent the water from passing through normally after dirt and dirt clogs the filter media, thus preventing the filter from not being able to output water and thus preventing it from malfunctioning.

[0084] In a preferred embodiment of this utility model, a lower housing 3 is also included, 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;

[0085] Furthermore, a bio-sponge is installed at the water inlet, which is prevented from detaching by a grille 3-1. The bio-sponge provides secondary filtration for large particles of dirt entering the water tank, allowing water to flow through while preventing the impeller from jamming and affecting its operation, and preventing dirt from rising with the water flow and being drunk by the pet.

[0086] The lower housing 3 has an impeller cavity 3-4 that accommodates the impeller; the outlet 3 is connected to the interior of the main body.

[0087] To facilitate the rotation of the impeller 6 and the discharge of water, the lower housing 2 forms a receiving space and an internal channel for water inlet and outlet.

[0088] In a preferred embodiment of this utility model, a Hall level sensing area is further provided inside the main body, and the Hall level sensing area is isolated from and not connected to the inner bracket and the flow channel.

[0089] Conventional water dispensers require electronic components to be submerged in water to detect low water levels, or their manufacturing process is complex and requires perforation. This invention cleverly integrates these components into the flow-guiding part, resulting in fewer overall parts in the water dispenser. The water tank contains only the flow-guiding part, and the detachable design of the flow-guiding part facilitates cleaning.

[0090] The Hall sensor circuit board is placed inside the base 14. The Hall water level sensing area stores the Hall float ball, which can float with the water level in the water tank. When the water level is lower than the minimum water level line, the Hall sensor circuit board inside the base 14 is triggered to alarm the low water level.

[0091] The outer shell of the flow-inducing component can be plastic and is connected to the fan blade plate 2. Internally, it has a reserved water channel and a space for storing a Hall effect float; these two parts exist independently and are not connected. The water channel connects two areas. One area stores filter materials such as coconut shell activated carbon and ion exchange resin, stacked in multiple layers in a three-dimensional manner. This allows for the adsorption of heavy metals, excess minerals (calcium and magnesium ions), and unpleasant colors and odors; it also reduces the probability of algae and larval reproduction and slows down the formation of biofilms (sticky substances). After the water flows through the pump into the filter element, it is filtered by the filter media. The other area leads directly to the filter element's outlet, ensuring that the filtered water can be discharged normally and preventing dirt from clogging the filter media, allowing water to flow through normally and preventing the filter from failing to output water or malfunctioning.

[0092] In a preferred embodiment of this utility model, a Hall level sensing area is further provided inside the main body. The Hall level sensing area is isolated from and not connected to the inner bracket and the flow channel. The Hall area extends from top to bottom through the main body and the lower shell.

[0093] The space for storing the float is vertically connected, ensuring that the float floats freely with changes in water level. When the water level rises, the float rises with the water level; when the water level falls, the float falls with the water level line, always remaining level with the water level. When the water level drops to the lower limit, a Hall sensor is triggered, and the ambient light on the base begins to flash slowly (once per second), triggering a low water level alarm and prompting the consumer to add water. During the water adding process, as the water level line rises, when the water level exceeds the lower limit, the Hall sensor disappears, the slow flashing of the ambient light (once per second) stops, and the low water level alarm is deactivated.

[0094] The main body and the lower housing are two separate components, and the through-type design increases the sensing range of the Hall element.

[0095] The lower housing 3 is provided with Hall inlet and outlet ports 3-5 at the bottom of the Hall zone, and the main body is also provided with a flow port at the top of the Hall zone. The vertical arrangement ensures the inflow and outflow of water, so that the Hall float can be kept in line with the horizontal line.

[0096] In addition, the flow-guiding component fits into the filter disc of the water dispenser. The top of the main body 1 has two protrusions, and the inner side of the top of the filter disc has two grooves. This way, even if the component is not installed correctly, when installing the filter disc, the main body and impeller assembly can be restricted to return to the correct position, and the grooves can be used to guide the assembly to ensure that it is installed in the correct position.

[0097] Specifically, the drainage component has a flat, cylindrical structure overall, with a cylindrical bottom and a conical top. See [link / reference needed]. Figure 1 The general shape is shown.

[0098] Example 2

[0099] See Figure 5-8 This utility model also relates to a pet water dispenser, wherein the water tank of the water dispenser includes a magnetically driven flow-guiding component.

[0100] Pet water fountains can be plugged in, or installed with batteries, or have a rechargeable design;

[0101] Configurable battery version, with a built-in 5000mAh or 10000mAh rechargeable battery.

[0102] In a preferred embodiment of this utility model, the return port of the drinking tray is located around the periphery of the diversion component, so that the returned water adheres to the outside of the diversion component and flows into the water storage tank.

[0103] The water tray uses a four-sided return system, meaning water can return from 360°. Compared to traditional pet water fountains that only have 1-3 return ports, this reduces the risk of overflow. In addition, in the filter tray, besides the standard 4 return ports, there are 2 additional return ports on the higher parts of both sides for return.

[0104] Specifically, the system includes a filter disc and a drinking water tray. The filter disc has a filter cartridge groove 19 and a second protrusion 22. Biochemical cotton is placed inside the filter cartridge groove 19. Four first return water inlets 20 are located near the outlet, and two second return water inlets 21 are located at the edge of the filter disc. All return water inlets are located above the drainage assembly, and the return water flows back along the edge of the drainage assembly. The second return water inlets 21 prevent excessive water tension from preventing water from returning.

[0105] The bio-cotton, placed inside the filter tray, allows water to flow through while intercepting large particles of dirt (hair, dust, slime, small food residue), preventing most of these large particles from entering the water tank and contaminating it.

[0106] Preferably, the second protrusion 22 lifts the drinking tray, and the drinking tray is smaller than the filter tray, so that the surrounding area between the two forms a return channel 16 to achieve 360° return.

[0107] The water dispenser includes a base 14 and a main body 13; the two are independent and separable components.

[0108] The drive mechanism is located inside the base 14. Preferably, the drive mechanism is a motor, and a rotating part is provided on the output shaft of the motor, and multiple magnet units are provided on the rotating part.

[0109] The impeller has four built-in magnets, and a plastic part (i.e., the rotating part) is nested above the rotor of the power motor. The plastic part also has four built-in magnets, which correspond to the magnets in the impeller. Two of the magnets have the same magnetic poles, and the other two have opposite magnetic poles. The magnetic force penetrates the water tank, which prevents the impeller from being completely attracted to the magnets above the motor and thus unable to rotate. At the same time, it can also be attracted by a certain magnetic force and rotate with the motor.

[0110] Preferably, the parts that come into direct contact with the pet's mouth and tongue during the drinking process (spray nozzle, water tray) are made of food-grade 304 stainless steel and food-grade ceramic materials to prevent bacterial growth and dirt accumulation, and to facilitate cleaning, thereby preventing pet skin diseases; at the same time, the inner water tank is made of food-grade 304 stainless steel and food-grade ceramic materials to prevent bacteria from growing at the source, and to facilitate cleaning, thereby preventing pet skin diseases.

[0111] Preferably, the spray nozzle is made of food-grade 304 stainless steel through one-piece stamping or food-grade ceramic through high-temperature firing, with a smooth and rounded structure without dead corners, making it less prone to dirt accumulation and easy to clean with water; the water tray is made of food-grade 304 stainless steel through one-piece stamping and edge rolling or food-grade ceramic through high-temperature firing, with a smooth and rounded structure without dead corners, making it less prone to dirt accumulation and easy to clean with water; the outer water tank is made of food-grade ABS through one-piece injection molding, with a smooth and rounded structure, and the bottom protrusion has rounded corners, making it less prone to dirt accumulation and easy to clean with water; the inner water tank is made of food-grade 304 stainless steel through one-piece stamping and edge rolling or food-grade ceramic through high-temperature firing, with a smooth and rounded structure, and the bottom protrusion has rounded corners, making it less prone to dirt accumulation and easy to clean with water.

[0112] The water flows back along the outer surface of the column diversion component, avoiding the noise caused by the water falling when the water level in the tank is low. This optimizes the noise problem of the pet water fountain and avoids the disturbance of water flow noise during daily use.

[0113] In a preferred embodiment of this utility model, the water dispenser body 13 and the base 14 are separately arranged, with the water dispenser body 13 sitting on the base 14; the drive mechanism inside the base 14 magnetically attracts the impeller of the diversion component inside the water storage tank and drives the impeller to rotate.

[0114] The inner water tank can be installed without damage. If a consumer only purchases the single water tank version and has upgrade needs later, they can purchase the inner water tank separately and install it without damage. The base can be replaced without damage. If a consumer purchases the basic configuration and has upgrade needs later, they can purchase the base separately to achieve different functions. It can be installed without damage and is fully compatible.

[0115] In a preferred embodiment of this utility model, the base includes a current detection circuit. When the current threshold is low, the motor rotates at low speed to assist the impeller in alignment; when the current threshold is high, the motor rotates at high speed to realize the pumping function.

[0116] The system determines whether the motor is operating normally by detecting the current. If the magnet above the motor inside the casing properly attracts the magnet inside the impeller, driving it to rotate normally, the load current will be relatively high. If it fails to attract the magnet properly, resulting in slippage, the current will be relatively low, equivalent to an open-circuit current. The difference between the load current and the open-circuit current is safe and can be detected by current sensing with a very low probability of false alarms. Therefore, the system determines whether slippage is occurring by detecting this current. If slippage is detected, meaning the open-circuit current is low, the motor will automatically slow down and attempt to attract the impeller; once attracted (albeit at low speed), which is equivalent to a higher load current, the motor will automatically increase its speed.

[0117] The above design solves the problems of slippage, different frequencies, and inability to rotate synchronously caused by the impeller's inability to adhere after the motor starts.

[0118] In a preferred embodiment of this utility model, the water tray and the water dispenser body 13 are locked together by a latch 17.

[0119] Safety locks 17 are installed on both sides of the main body 13 of the water dispenser, which can fix the filter tray and prevent it from being easily opened, thus preventing problems such as overflow, spillage, and the water dispenser malfunctioning due to pets disassembling the machine.

[0120] The main body 13 of the water dispenser is the outer water tank. The main electronic components of this utility model are integrated on the base 14. The main body only has the water tank, filter plate, drinking plate and internal diversion components, all of which are non-electric. The main unit and the base are designed to be detachable, which facilitates the cleaning of the whole machine. The main unit can be rinsed with water to clean it, which is convenient for users.

[0121] The water storage tank contains only one unit, the diversion component, which is also designed to be non-electric. The diversion component is also easy to disassemble and clean.

[0122] Preferably, the safety buckle of the outer water tank is made of PP material and has a segmented design with a total of 2 components. While being compatible with different water tanks, the PP material can achieve a safe lock, and due to the material properties, it also retains a certain deformation space to prevent breakage. The connection between the two components is made of metal shaft, which increases rigidity while allowing for flexible and unobstructed rotation. The connection between the safety buckle and the water tank also uses metal shaft, which increases rigidity while allowing for flexible and unobstructed rotation.

[0123] This utility model 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. By combining the different colors and processes of the two water tanks, various combined appearance effects can be produced.

[0124] The water tank features a non-destructive installation design. The filter disc's edge has a pre-drilled groove on the inner side. When the outer water tank is used alone, the groove completely secures and tightens it, preventing deformation and ensuring stable placement. When the outer and inner water tanks are used together, the edges can be placed stably, allowing for compatibility between two different usage methods. The outer water tank's safety buckle is a segmented design with two components. The upper component has an interference fit, allowing for some movement when using the outer water tank alone while effectively securing it. The tank and filter tray; when the outer and inner water tanks are used together, the height difference increases, but the interference fit design compensates for the lack of movement space and still effectively fixes the outer water tank and filter tray, achieving design compatibility; the water pump base is compatible with both the outer and inner water tanks, and the bottom of both tanks has designated installation positions that are visible to the naked eye to assist in positioning; at the same time, the thickness of the outer and inner water tanks is controlled to ensure that the magnetic force can effectively attract the impeller whether the outer water tank is used alone or in combination with the inner water tank, achieving structural compatibility;

[0125] The base is compatible with both the battery version and the basic version. The base structure is designed with a reserved battery installation position, and the size is designed according to a 50000mAh battery. There is one on each side, for a total of two reserved positions. When the battery is not needed, the battery accessories can be removed. When the battery is needed, you can choose to use a 5000mAh battery to power the device alone or two 5000mAh batteries in parallel or series to power the device, thus forming a larger battery capacity.

[0126] The base 14 is equipped with an ambient light, and the outer water tank is made of transparent material or transparent frosted finish. The ambient light stays on when plugged in and can be turned off by pressing a button. At the same time, the ambient light provides users with a good visual experience and brings them a pleasant mood.

[0127] The water dispenser base is also equipped with a radar sensor module. When the radar sensor module detects a moving object, water will be dispensed for 10-30 seconds. During the water dispensing action, the ambient light will light up for 3 seconds, and can be turned off via a button. These settings can save electricity, especially when the device is powered by battery.

[0128] Whether plugged in or battery powered, the ambient light also has several control modes: when a moving object is detected, the ambient light illuminates for N seconds; when the battery level is below a threshold, the ambient light flashes at a first speed; when the water level is below a threshold, the ambient light flashes at a second speed; and when the device is charging, the ambient light gradually turns off / on.

[0129] Specifically, when the device triggers a low battery alarm (battery level ≤ 20%), the ambient light flashes rapidly (once every 0.5 seconds), and the alarm will still sound even if the ambient light is off; when the device triggers a low water level alarm (water level below the lower limit), the ambient light flashes rapidly (once every 1 second), and the alarm will still sound even if the ambient light is off; when the device is charging, the ambient light flashes in a breathing pattern (gradually turning off / on within 1 second), and the alert will still sound even if the ambient light is off.

[0130] The base structure has reserved battery installation positions, designed for a 50000mAh battery, with one on each side, for a total of two. When it is not possible to plug in at all times, you can choose to use a single 5000mAh battery for power supply or two 5000mAh batteries in parallel or series to form a larger battery capacity.

[0131] Preferably, to facilitate the positioning of the water storage tank, the top of the base 14 is also provided with a positioning part 18. The positioning part 18 can be a protrusion, a groove, or other limiting components, such as a column, point, rib, wall, etc. Of course, the two can also be nested together.

[0132] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this application. It should be understood that the above description is only a specific embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
