Description

Technical Field

[0001] This utility model belongs to the technical field of water distribution equipment, specifically relating to a multi-nozzle water distribution device. Specifically, this device can simultaneously distribute water flow through multiple nozzles or outlets to meet the concurrent usage needs of multiple users. Background Technology

[0002] A water dispenser is a device used to supply drinking water. Users typically control the nozzle to release stored water by operating a lever or pressing a button. During operation, the valve opens to dispense water, and releasing the operating component (such as a lever or button) stops the water flow, allowing users to precisely control the amount of water dispensed. Currently, many different types of water dispensers have been developed on the market. Generally speaking, they can be divided into two types based on the water supply method: storage-type and instant-drink type.

[0003] Storage-type water dispensers store purified water in a tank and supply it when the user activates the dispensing device; while instant-drink water dispensers filter raw water in real time, providing purified water without storage. In addition to room temperature drinking water, modern water dispensers typically also have heating and cooling functions: the heating system heats the purified water to provide hot water, while the cooling system cools the water to provide cold water. For example:

[0004] Australian patent document No. 2018340856 proposes a drinking water system that can supply hot and cold water according to user needs; Korean patent document No. 102053784 discloses a water storage drinking water system with anti-condensation design to avoid drain pipe blockage; Zhang's team further developed an intelligent water dispenser in US patent No. 10866599, which can receive multiple user commands and execute water dispensing according to priority.

[0005] However, none of the aforementioned systems can simultaneously provide water to multiple users on demand. In large events or public places (such as airports), participants often waste time queuing for water, negatively impacting their experience. Therefore, there is an urgent need for a water distribution device that can simultaneously meet the varying water demands of multiple users. Utility Model Content

[0007] Another objective of this invention is to provide a multi-user synchronous water supply system. This device integrates multiple water nozzles, enabling it to provide drinking water to multiple users simultaneously. Specifically, the device allows users to select a preset water volume through an interface to meet the personalized needs of different users.

[0008] Another objective of this invention is to provide a portable water distribution system. In particular, the device can be disassembled into several components to improve portability; this modular design facilitates both storage and transportation.

[0044] See Figure 1 and Figure 2 This utility model discloses a multi-nozzle water distribution device, comprising:

[0045] A base 110; a hollow column 120 extending vertically along the base 110; multiple water distribution arms 130, which extend radially outward from the column 120 on a horizontal plane and are spaced apart from each other, i.e., the multiple water distribution arms 130 are distributed circumferentially around the column 120 and located on the same horizontal plane, and each water distribution arm 130 has a water outlet nozzle 132 at its end (i.e., the end away from the column 120) facing the base 110; a water pump 140 disposed in the column 120 or the base 110; a connecting pipe 145 (preferably a flexible connecting pipe 145) connecting the water pump 140 and a water source to establish a fluid passage; a manifold 150 connecting the water pump 140 and the multiple nozzles 132 to form a water flow channel through the water pump, i.e., multiple fluid branches can be formed between the multiple nozzles 132 and the water pump 140 through the manifold 150; and multiple solenoid valves 1. 70, respectively set at the position of the manifold 150 corresponding to each nozzle 132, for regulating the water flow rate and / or water volume; control panel 160 set on each water distribution arm 130, the control panel 160 integrates a control circuit 161, the circuit is connected to the solenoid valve 170 through the microcontroller to realize the control of the water output parameters of the corresponding nozzle 132, each control panel 160 is provided with several interactive buttons 162 / 163, which can generate electrical signals corresponding to different working modes; liquid flow sensor 180 communicating with the microcontroller, used to monitor the water flow rate / water volume and generate relevant sensing signals; and power module 190 for powering each power module, the power module 190 is used to power the water pump 140, solenoid valve 170, control panel 160, control circuit 161 and liquid flow sensor 180, preferably, each control panel 160 can be configured to output equal or different water volumes at the same time.

[0046] In some embodiments, the base 110 is made of lightweight, high-strength engineering plastics, such as acrylonitrile-butadiene-styrene copolymer (ABS), polyethylene terephthalate-1,4-cyclohexanediol (PETG), polylactic acid (PLA), etc. In some embodiments, the base 110 is a disc-shaped structure with a relatively large thickness to provide sufficient structural strength to support the weight of multiple containers placed on it during water dispensing. Specifically, the base 110 can be composed of an upper shell 111 and a lower shell 112, wherein the upper shell 111 has a horizontal top surface and a downwardly extending annular sidewall, and the lower shell 112 has a horizontal bottom surface and an upwardly extending annular sidewall. The two shells are joined together to form the base 110, which forms a hollow cavity inside. The top and bottom edges are machined with corresponding overlapping structures to allow the top and bottom shells to be seamlessly joined. Preferably, the cavity is provided with a reinforcing structure to enhance the stability of the base 110. For example, a raised reinforcing rib, block-shaped or strip-shaped support is provided between the inner top wall of the bottom surface and the inner bottom wall of the top surface to resist external forces. In addition, in some embodiments, the reinforcing structure of the lower housing 112 can extend to the cavity area of ​​the upper housing 111. These reinforcing structures may be provided with one or more snap-fit ​​female connectors for engaging with corresponding male connectors extending from the bottom of the lower plane of the upper housing 111, thereby achieving a tight fixation between the top and bottom bodies to achieve a tight fit. The lower plane of the lower housing 112 may also be machined to form a first through hole (preferably a through-hole first channel) for engaging with the sealing cap assembly of the drinking water bucket, thereby achieving such... Figure 5The installation and positioning of the device 100 is shown. To ensure the stability of the device 100 on the drinking water bucket, in some embodiments, the bottom of the base 110 is also provided with several elastically retractable support legs or gripping mechanisms for contacting or locking the body of the drinking water bucket. Preferably, each support leg / grip mechanism is elastically hinged to the lower surface of the lower housing 112 by a torsion spring. When the base 110 is lifted or removed from the drinking water bucket, the torsion spring can automatically drive the support legs / grip mechanism to retract into the lower housing 112. In other embodiments, the base 110 is also provided with recessed limiting grooves 113, the contour of which is adapted to the bottom of the container placed on top of the base 110, for receiving the discharged water flow. Specifically, these limiting grooves 113 are formed on the upper surface of the upper housing 111, and their contours mark the reference positioning area of ​​the container, ensuring that the discharged water flow can be accurately injected into the container during water dispensing. The slightly raised edges around the limiting grooves 113 can help fix the placement position of the container. In other embodiments, the outer edge of the upper plane is also provided with a slightly convex anti-overflow guard, which can effectively prevent liquid from splashing onto the surface of the upper housing 111 and prevent water from leaking onto the ground or the drinking water tank. A second through hole 115, coaxial with the first through hole, is provided at the center of the top surface of the base 110 for inserting the lower end of the column 120, together forming a vertical channel for drawing water from the drinking water tank. This coaxial design ensures that the fluid flows without turbulence along its path while maintaining the overall structural stability of the device.

[0047] Furthermore, in some embodiments, the hollow column 120 extending vertically from the base 110 preferably has a generally circular or square horizontal cross-section, with a closed channel 124 at its center for accommodating or housing various functional components to enable the operation of the device 100. Similarly, the column 120 is made of materials such as ABS, PETG, or PLA. The column 120 typically includes an elongated rod 121, the upper end 122 of which is connected to the water distribution arm 130, and the lower end 123 of which is connected to the second through hole 115. It should be noted that the column 120 is detachably fixed to the base 110 to improve the portability of the device. The column 120 can be connected to the base 110 by threaded engagement or snap-fit ​​engagement. In more embodiments, the column 120 employs a telescopic structure to achieve vertical height adjustment. Specifically, the column 120 may consist of two interlocking parts connected by a telescopic structure to achieve an extension function. In these embodiments, the extension of the length of the column 120 allows the device to be adapted to taller or longer containers during drainage.

[0048] In some embodiments, a plurality of water distribution arms 130 extend horizontally around the upper end of the column 120 (i.e., the end away from the base 110). The length of the water distribution arms 130 preferably does not exceed the radius of the base 110 to ensure that the nozzle 132 can be accurately aligned with the container opening to achieve precise water supply. The number of water distribution arms 130 is preferably 2 to 8, more preferably 3 to 4. For embodiments with more water distribution arms 130, the length of the water distribution arms 130 can be increased accordingly, so that the nozzles 132 on each water distribution arm 130 are more radially spaced, thereby forming a larger space between two adjacent water distribution arms 130, which facilitates placing the container on the base 110; preferably, a plurality of water distribution arms 130 are arranged radially at equal intervals around the column 120, that is, multiple water distribution arms 130 are evenly arranged along the circumference of the column 120, and the internal space of each water distribution arm 130 is connected to the cavity 124 inside the column to form a continuous pipeline space to accommodate the solenoid valve 170, control panel 160, control circuit 161, lighting module 200, manifold 150 and nozzles 132, etc. (see details) Figure 5 Preferably, a through hole is provided at the bottom of the free end of the water distribution arm 130 suspended above the base 110 for mounting the nozzle 132. At least two function buttons are provided on the top surface of the water distribution arm 130 to form the core operating interface of the control panel 160; these buttons allow the user to interact and select the operating mode. Specifically, these buttons are connected to the control circuit 161 arranged below, triggering different signals to select the mode, together forming the operating components of the control panel 160.

[0049] In some embodiments, such as Figure 5As shown, the water pump 140 in this device is housed inside the column 120 and is used to drive the liquid (e.g., water) through the entire system and maintain a stable flow of water within the system, ensuring that each outlet receives the required amount of water when the corresponding solenoid valve 170 is opened. More preferably, the water pump 140 ensures that the liquid flows at the expected flow rate and pressure, thereby enabling precise water flow measurement and control of the device. By maintaining a stable water flow output, the water pump 140 ensures efficient and reliable operation of the device. Preferably, the water pump 140 is directly or indirectly electrically connected to the power module 190 to obtain driving power and draws water from the drinking water tank through a hose. The water pump 140 includes a pump body with an inlet at the bottom and an outlet at the top. The inlet is connected to a connecting pipe 145, and the outlet is connected to a manifold 150, thereby establishing a fluid passage. Specifically, the water pump 140 draws water from the drinking water tank through the connecting pipe 145 and then directs the water flow to the nozzle 132, dispensing water when the user issues a command through the control panel 160. Connecting pipe 145 and / or manifold 150 can be securely connected to water pump 140 via a connector. In some embodiments, water pump 140 is a variable displacement pump, and the flow rate of the device can be adjusted not only by solenoid valve 170 but also directly by control panel 160, realizing the dual flow control function of device 100. In other embodiments, water pump 140 is preferably a metering pump, delivering water at a fixed or preset flow rate, in which case the flow rate and volume of the water are completely controlled by solenoid valve 170.

[0050] In some embodiments, the connecting pipe 145 is preferably a silicone tube, one end of which is connected to the inlet of the water pump 140, and the other end is immersed in the drinking water tank to establish a fluid passage. It should be noted that the connecting pipe 145 may be composed of multiple segments rather than a single integral structure. For example, in an embodiment where the column 120 and the base 110 are separable, the connecting pipe 145 may include: a first pipe segment, one end of which is fixed to a first sprinkler (not shown) in the first through hole of the base 110, and the other end is immersed in the drinking water tank; a second pipe segment, one end of which is connected to a second sprinkler (not shown) in the second through hole 115, and the other end is fixed to the inlet of the water pump 140; and an optional intermediate pipe segment for connecting the two sprinklers (the first pipe segment and the second pipe segment). In other embodiments, the connecting pipe 145 is a single silicone tube, one end of which is inserted into the drinking water tank, and the other end passes through the first through hole and the second through hole 115 sequentially before being fixed to the inlet of the water pump 140. Preferably, the end of the connecting pipe 145 extending into the drinking water tank is provided with a countersunk structure to optimize the utilization rate of water resources in the tank. The branch pipes of the manifold 150 can also adopt a segmented structure to achieve fluid connection between the water pump 140 and each nozzle 132. Specifically, the first branch section of the manifold 150 extends from the outlet of the water pump 140 to the distributor 151; subsequently, it divides into multiple branch sections: after branching from the manifold 150, they lead to each distribution arm 130, and finally connect to the corresponding nozzle 132. Several sections of the manifold 150 are made of food-grade plastics, including but not limited to polypropylene (PP), high-density polyethylene (HDPE), low-density polyethylene (LDPE), nylon, etc., to ensure that the transported water flow is not contaminated by device components.

[0051] It should be noted that each branch of the manifold 150 is equipped with an independent solenoid valve 170. This solenoid valve 170 is electrically connected to the control circuit 161 of the corresponding control panel 160 and is operated via interactive buttons 162 / 163 on the water distribution arm 130. As the core component controlling water flow, the solenoid valve 170 precisely regulates the water flow through the device 100 by opening and closing the valve body driven by an electromagnetic coil. When current passes through the electromagnetic coil, the generated magnetic field drives the plunger to move, thus opening and closing the solenoid valve 170. This mechanism can precisely control the flow rate and direction of water towards the nozzle 132. Typically, each branch of the manifold 150 connected to the nozzle 132 is equipped with an independent solenoid valve 170. When the control circuit 161 receives an opening signal from the control panel 160, it energizes the electromagnet to generate a magnetic field, driving the plunger to open the valve port and allow water to flow through. When a closing signal is received, the power is cut off, and the valve core resets to cut off the water flow. Depending on the implementation method, each solenoid valve 170 achieves differentiated opening control by adjusting the current intensity of the input solenoid coil according to the mode selected by the user through the control panel 160 of the corresponding water distribution arm 130. In another implementation method, the device 100 can use a valve body control with a standard opening degree, but achieves precise regulation of the water output by adjusting the opening duration and / or power supply duration of the solenoid valve 170 (matching the mode selected by the user). Figure 5 As shown, each solenoid valve 170 is located at the end of the fluid branch (i.e., upstream of the nozzle 132) to precisely control the water flow rate and / or total water output of the corresponding nozzle 132.

[0052] To achieve precise flow and / or water volume control, this device preferably includes a liquid flow sensor 180. In some embodiments, the flow sensor 180 monitors the flow parameters of each outlet in real time, and this information is transmitted to a control circuit 161. This circuit dynamically adjusts the operating states of the solenoid valve 170 and the water pump 140 to maintain the required flow rate and pressure. Alternatively, the microcontroller of the control circuit 161 can process this information or signal to dynamically adjust the operating states of components such as the solenoid valve 170 and the water pump 140, thereby ensuring efficient system operation and maintaining the required flow rate and direction. Figure 5In the illustrated embodiment, sensor 180 may be located on a section of hose 145 upstream of the inlet of water pump 140, i.e., on the connecting pipe 145 and before the inlet of water pump 140, to generate a signal related to the flow rate of water and transmit the signal to power circuit 191 and / or control circuit 161. When a signal indicating that a selected amount of water has been discharged is received, control circuit 161 or power circuit 191 may stop the operation of water pump 140, or independent control circuit 161 may close the corresponding solenoid valve 170. In further embodiments, branches of manifold 150 may be configured with liquid flow sensors 180 to measure the flow rate of water or liquid flowing through them and transmit the generated signal to the corresponding control circuit 161 to maintain the open state of solenoid valve 170 or trigger solenoid valve 170 to close. In some embodiments, the solenoid valve 170 is configured to discharge water at a rate of approximately 0.5 liters to 1.2 liters per minute.

[0053] In some embodiments, multiple control panels 160 are respectively disposed on each water distribution arm 130. Each control panel 160 is provided with multiple buttons for user operation, used to switch the start and stop states of water dispensing. Buttons 162 / 163 also allow the user to select an operating mode before starting the water dispensing operation. The operating modes include a first mode, a second mode, and a third mode, corresponding to dispensing water through the nozzle 132 at a first water volume, a second water volume, and a third water volume, respectively. Preferably, the first water volume is greater than the second water volume, and the second water volume is greater than the third water volume. More preferably, the first water volume is 1500 ml to 2000 ml, the second water volume is 800 ml to 1200 ml, and the third water volume is 100 ml to 500 ml. Figure 3The diagram illustrates an embodiment of the user interface for the control panel 160, including interactive buttons for mode selection. Specifically, the control panel 160 includes a first button and a second button, where the first button is used for mode selection, and the second button is used to control the start and stop of the water dispensing operation after mode selection. The panel also features three different icons 164, representing the first mode, second mode, and third mode, respectively. Pressing the first button illuminates an indicator light to display the current selection. Repeatedly pressing the first button cycles through the first, second, and third modes. After selecting the desired mode, the user can press the second button to initiate the water dispensing operation in that selected mode. When the control panel 160 is activated, the water pump 140 starts, simultaneously opening the corresponding solenoid valve 170. Once the water volume corresponding to the selected mode has been completely discharged, the device 100 will stop the operation of the corresponding water distribution arm 130. In more embodiments, the pumping rate of the water pump 140 can be set to be higher than the allowable flow rate of the solenoid valve 170, thereby ensuring that the system can still maintain a stable flow distribution when multiple control panels 160 start discharging water simultaneously. The valve opening duration and opening size ultimately determine the total amount of water delivered to the container, thus preventing container overflow even when there is a large flow at the water pump 140 end. The user can press the second button again before the water discharging operation ends to achieve an emergency stop. In some embodiments, if the second button is activated directly without selecting a mode through the first button, the system will default to triggering the first mode. In addition, the activated control panel 160 can automatically switch to sleep mode after no button operation is detected for a continuous period of time (preferably 1 to 5 minutes); pressing any button can wake up the corresponding control panel 160. Furthermore, the control circuit 161 or control circuit 161 board of each control panel 160 is usually responsible for managing and coordinating the various components of the system. This circuit precisely controls the operation of the solenoid valve 170, power supply circuit 191, lighting module 200 or backlight assembly, and water pump 140 by processing signals from sensor 180 and other input terminals. Through the analysis and processing of these signals, control circuit 161 ensures that the device always maintains a highly efficient and accurate operating state, and maintains precise control of the required flow rate and direction.

[0054] In further embodiments, the device also includes a lighting module 200 for backlighting at least one interactive button (partial structure as shown in the image). Figure 4(As shown). For example, the mode selection button (i.e., the first button) and the selected mode are illuminated by the lighting module 200. The lighting module 200 is arranged close to the lower side of the top panel of the arm body, and the icon 164 and / or the button are at least partially made of light-transmitting material or treated with light-transmitting technology. In addition, in some embodiments, the lighting module 200 may illuminate the icon 164 and / or the button with at least two levels of brightness. Specifically, when the control panel 160 is active, the button and icon 164 are illuminated at a first brightness level (lower brightness), which is lower than the second brightness level, and the lighting module 200 illuminates the icon 164 corresponding to the selected mode at the second brightness level, thereby clearly indicating the currently selected mode. Similarly, when the water dispensing operation is in progress, the second button is illuminated at the second brightness level, and switches back to the first brightness level after the operation stops.

[0055] As described in the foregoing embodiments, the power module 190 provides power (but is not limited to) to the following components for operation: water pump 140, solenoid valve 170, control panel 160, lighting module 200, control circuit 161, and sensor 180. Preferably, the power module 190 further includes a power circuit 191 for regulating the power supplied to the water pump 140, solenoid valve 170, control panel 160, lighting module 200, control circuit 161, and sensor 180. The power circuit 191 ensures that power is supplied to the components without causing damage through voltage regulation. The power circuit 191 can also communicate with the control panel 160 or control circuit 161, and stop supplying power to the water pump 140 upon receiving a cut-off signal when a selected amount of water has been discharged. In some embodiments, the power module 190 further includes a rechargeable battery 193 with an input port for receiving power from an external power source for charging. In some specific embodiments, the rechargeable battery 193 may serve as the sole power source for driving the various components of the device. Preferably, the rechargeable battery 193 has a capacity of 1000 to 5000 mAh. However, in other embodiments, the power supply circuit 191 can operate directly using an external power supply via the input port. More preferably, the input port is a USB-C interface, which enables fast charging based on the Power Delivery (PD) protocol with the support of the power supply circuit 191. When the input port is not in use, a sealing ring can be configured for visual concealment.
