Description

Technical Field

[0001] This utility model relates to the field of direct drinking water station technology, specifically to a direct drinking water station that can adapt to water buckets of different sizes and hygiene requirements. Background Technology

[0002] Direct drinking water stations are water purification devices installed in communities, public places, and other areas. They deeply purify tap water using RO reverse osmosis or nanofiltration technology, effectively removing bacteria, heavy metals, and other harmful substances while retaining beneficial minerals such as calcium and magnesium, ensuring the water is safe for direct consumption. The equipment features intelligent management functions, supporting real-time water quality monitoring and automatic filter replacement reminders, and avoids secondary pollution through a circulating pipe network. Widely covering communities, schools, hospitals, and other scenarios, they meet residents' needs for drinking water and tea brewing, contributing to the upgrading of urban public services, reducing plastic pollution, promoting the sustainable development of differentiated water supply, and becoming an important component of modern urban healthy drinking water infrastructure.

[0003] In existing technologies, the water buckets in current direct drinking water stations are of fixed size and use standardized buckets. Some individuals need larger buckets (over 20L), which cannot be placed in the water tank, thus preventing them from drawing water. The water outlets of existing equipment are mostly exposed, directly exposed to the external environment during operation. Dust, microorganisms, and other pollutants in the air may enter the water tank when the door is open, thus contaminating the water outlet. Accidental contact by the operator during bucket replacement may also cause secondary pollution. This open structure cannot effectively block environmental pollutants, posing a risk to drinking water hygiene and safety, and does not meet the basic hygiene requirements of modern healthy drinking water equipment. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art, and thus propose a direct drinking water station that can adapt to water buckets of different sizes and hygiene standards. This invention provides two water collection methods by setting up a pure water collection tank and a mineral water collection tank, and providing side platforms on both sides, enabling water to be collected from water buckets of different sizes. The nested design of the nozzle and the rigid water pipe allows the nozzle to slide along the inner wall of the rigid water pipe. Specifically, the movement range is limited by a circular baffle. A first spring provides a restoring force, causing the nozzle to retract into the rigid water pipe when not in use, preventing nozzle contamination and improving hygiene quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A direct drinking water station adaptable to different sized water buckets and hygiene standards includes a housing and a water intake chamber housed within the housing. The water intake chamber comprises a purified water intake chamber and a mineral water intake chamber arranged side-by-side. Each of the purified and mineral water intake chambers has a front door, and their outer sides have side doors. A nozzle holder is installed inside the water intake chamber, and a water nozzle is mounted on the holder. A solenoid valve is installed inside the water nozzle. A self-expanding flexible hose is connected above the water nozzle, and the other end of the flexible hose is housed within an automatic hose reel. The water gun has a gripper at the lower end, and a side platform is provided on the side of the housing. The side platform is located below the side door. Controllers are respectively provided above the pure water intake chamber and the mineral water intake chamber. The water gun includes a rigid water pipe and a nozzle. The rigid water pipe is hollow at the top and connected to a self-expanding flexible hose. A first annular baffle is provided on the inner side below the rigid water pipe. The nozzle is located inside the rigid water pipe. A second annular baffle is provided on the outer side above the nozzle. Water holes are provided on the side wall of the nozzle. The bottom of the nozzle is closed. A first spring is provided between the first and second annular baffles.

[0007] Preferably, the rigid water pipe has two handles on its side, which are perpendicular to each other and are perpendicular to the front door and the side door, respectively. The rigid water pipe has an iron plate on its side, which is located opposite the handles.

[0008] Preferably, the outer diameter of the second annular baffle is equal to the inner diameter of the hard water pipe, the inner diameter of the second annular baffle is equal to the inner diameter of the nozzle, the outer diameter of the first annular baffle is equal to the outer diameter of the hard water pipe, and the inner diameter of the first annular baffle is equal to the outer diameter of the nozzle.

[0009] Preferably, the water holes are angled downwards.

[0010] Preferably, the gun holder includes a connector and an arc-shaped plate. One end of the connector is connected to the inside of the water intake chamber, and the other end is connected to the outer wall of the arc-shaped plate. An electromagnet is provided on the inner wall of the arc-shaped plate, and the iron sheet is placed on the inner wall of the electromagnet.

[0011] Preferably, the gripper includes a ring, and a first connecting rod is provided on the side wall of the ring. The other end of the first connecting rod is hinged to a second connecting rod. A second spring is provided on the inner side of the first connecting rod and the second connecting rod. One end of the second spring is connected to the middle of the inner side of the first connecting rod, and the other end of the second spring is connected to the middle of the inner side of the second connecting rod.

[0012] Preferably, the lower end of the second connecting rod is provided with a reverse arc, and a rubber pad is provided on the outer surface of the arc.

[0013] Preferably, the controller is electrically connected to the solenoid valve, the automatic hose reel, the main door, the side door, and the electromagnet.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model provides two water intake methods by setting up a pure water intake chamber and a mineral water intake chamber, and setting side platforms on both sides, which can accommodate water buckets of different sizes. The nested design of the nozzle and the rigid water pipe allows the nozzle to slide along the inner wall of the rigid water pipe. Specifically, the movement range can be limited by a ring-shaped baffle. The first spring provides a restoring force, so that the nozzle retracts into the rigid water pipe when not in use. The closed structure of the water gun effectively prevents dust and microorganisms from adhering during the period of non-use, avoids nozzle contamination, and improves hygiene quality.

[0016] 2. This utility model features two handles, allowing the operator to retrieve water from either the front or side door without adjusting their grip. The symmetrical arrangement of the iron plate and electromagnet avoids interference from the magnetic adsorption by the handle structure, improving the stability of the water gun in a suspended state and effectively preventing accidental detachment when not in use.

[0017] 3. This utility model features downward-sloping water holes. When the water gun is in operation, the water flow forms a directional spray trajectory through the downward-sloping water holes, preventing splashing or large-area contact with air caused by horizontal or vertical spraying. When not in operation, the downward-sloping hole shape creates a downward-sloping shielding surface at the opening of the water hole, reducing the deposition area of ​​dust or microorganisms at the edge of the hole.

[0018] 4. This utility model uses a first connecting rod and a second connecting rod to form a hinged arm. The synergistic effect of the hinged arm and the spring enables dual adaptive adjustment of the clamping angle and clamping force, eliminating clamping failure caused by size differences while maintaining structural symmetry.

[0026] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0027] like Figures 1-6 As shown, a direct drinking water station adaptable to different sized water buckets and hygiene standards includes a housing 1 and a water intake chamber 2 disposed within the housing 1. The water intake chamber 2 includes a purified water intake chamber 21 and a mineral water intake chamber 22 arranged side by side. A front door 3 is provided on the front of each of the purified water intake chamber 21 and the mineral water intake chamber 22, and a side door 4 is provided on the outer side of each. A water gun holder 6 is disposed inside the water intake chamber 2, and a water gun 5 is disposed on the water gun holder 6. A solenoid valve is disposed inside the water gun 5. A self-expanding flexible hose 10 is connected above the water gun 5, and the other end of the self-expanding flexible hose 10 is disposed inside an automatic hose reel. The lower end of the gun 5 is provided with a gripper 7, and the side of the box 1 is provided with a side platform 8, which is located below the side door 4. Controllers 9 are respectively provided above the pure water intake chamber 21 and the mineral water intake chamber 22. The water gun 5 includes a rigid water pipe 51 and a gun head 54. The upper part of the rigid water pipe 51 is hollow and connected to the self-expanding flexible hose 10. A first annular baffle is provided on its lower inner side. The gun head 54 is located inside the rigid water pipe 51. A second annular baffle is provided on the upper outer side of the gun head 54. Water holes 541 are provided on the side wall of the gun head 54. The lower part of the gun head 54 is closed. A first spring 55 is provided between the first annular baffle and the second annular baffle.

[0028] It should be noted that the pure water tank 21 and the mineral water tank 22 provide different water qualities to meet the user's needs for water quality selection. When the user places a small water bucket, he / she can open the front door 3, put the water bucket into the water tank 2, remove the water gun 5 and insert it into the water bucket to start adding water. For large water buckets, the user opens the side door 4, places the water bucket on the side platform 8, pulls out the self-retracting hose 10 so that the water gun 5 reaches above the bucket opening, and the clamp 7 fixes the bucket opening before water can be added.

[0029] like Figures 2-4As shown, the rigid water pipe 51 has two handles 52 on its side, which are perpendicular to each other. The two handles 52 are perpendicular to the main door 3 and the side door 4, respectively. The rigid water pipe 51 has an iron plate 53 on its side, which is located opposite the handles 52.

[0030] It should be noted that the operator does not need to adjust their grip posture to complete the water dispensing operation through the front door 3 or the side door 4 due to the discomfort caused by different door opening directions. The symmetrical layout of the iron plate 53 and the electromagnet 63 avoids interference from the grip structure on the magnetic adsorption, thereby improving the stability of the water gun 5 in the suspended state and effectively preventing accidental detachment when not in use.

[0031] like Figures 3-5 As shown, the outer diameter of the second annular baffle is equal to the inner diameter of the hard water pipe 51, the inner diameter of the second annular baffle is equal to the inner diameter of the nozzle 54, the outer diameter of the first annular baffle is equal to the outer diameter of the hard water pipe 51, the inner diameter of the first annular baffle is equal to the outer diameter of the nozzle 54, and the water hole 541 is inclined downward.

[0032] It should be noted that during the extension and retraction adjustment of the nozzle 54, the contact interface between the water flow channel and the external environment is continuously sealed to avoid water leakage caused by poor sealing. At the same time, it prevents dust, microorganisms and other pollutants from entering the interior of the water nozzle 5 through the gaps between the components, ensuring the equipment sealing reliability and drinking water hygiene and safety when taking water from buckets of different heights.

[0033] like Figure 6 As shown, the fixed gun holder 6 includes a connector 61 and an arc-shaped plate 62. One end of the connector 61 is connected to the inside of the water intake chamber 2, and the other end is connected to the outer wall of the arc-shaped plate 62. An electromagnet 63 is provided on the inner wall of the arc-shaped plate 62, and the iron sheet 53 is placed on the inner wall of the electromagnet 63. The combination of electromagnetic adsorption and curved surface limiting allows for single-handed operation to complete the picking and placing action, while avoiding the physical wear problem of mechanical buckles.

[0034] like Figure 3 and Figure 4 As shown, the gripper 7 includes a ring 71, a first connecting rod 72 is provided on the side wall of the ring 71, and a second connecting rod 73 is hinged to the other end of the first connecting rod 72. A second spring 74 is provided on the inner side of the first connecting rod 72 and the second connecting rod 73. One end of the second spring 74 is connected to the middle of the inner side of the first connecting rod 72, and the other end of the second spring 74 is connected to the middle of the inner side of the second connecting rod 73. A reverse arc is provided at the lower end of the second connecting rod 73, and a rubber pad 75 is provided on the outer surface of the arc.

[0035] It should be noted that the first connecting rod 72 and the second connecting rod 73 constitute a hinge arm. The synergistic effect of the hinge arm and the spring enables dual adaptive adjustment of the clamping angle and clamping force, eliminating clamping failure caused by size differences while maintaining structural symmetry. The reverse arc at the lower end of the second connecting rod 73 can be adapted to water inlets of different sizes on the bucket.

[0036] The controller 9 is electrically connected to the solenoid valve, the automatic hose reel, the main door 3, the side door 4, and the electromagnet 63.

[0037] This utility model discloses the method of using the device.

[0038] 1. Users can choose between pure water tank 21 and mineral water tank 22 according to their needs, and choose whether to take water from the water tank 2 or place it on the side platform 8 to take water, depending on the size of the water bucket they bring;

[0039] 2. The user swipes their card and opens the corresponding main door 3 or side door 4 by pressing the button on the controller 9. If the main door 3 is opened, the user places the water bucket in the water inlet 2, holds the handle 52 facing the main door 3, and releases the water gun 5 from the fixed gun holder 6. The user inserts the rigid water pipe 51 of the water gun 5 into the water inlet of the water bucket, and the clamp 7 clamps the outer wall of the water inlet of the water bucket. By pressing the button on the controller 9, the solenoid valve opens. Under the action of water pressure, the nozzle 54 compresses the first spring 55 and moves downward to expose the water hole 541, and begins to drain water until the bucket is full.

[0040] 3. If the side door 4 is open, place the bucket on the side platform 8, hold the handle 52 facing the side door 4, and release the water gun 5 from the fixed gun holder 6. The self-extending hose 10 can ensure that the water gun 5 can move a long distance. Insert the rigid water pipe 51 of the water gun 5 into the water inlet of the bucket. The clamp 7 clamps the outer wall of the water inlet of the bucket. By operating the button on the controller 9, the solenoid valve is opened. Under the action of water pressure, the gun head 54 compresses the first spring 55 and moves downward, exposing the water hole 541, and starts to drain water until it is full of water.

[0041] 4. After filling the water tank, return the water gun 5 to the gun holder 6, and at the same time, the automatic hose reel retracts the self-extending hose 10, remove the water tank, close the main door 3 or the side door 4, and take out the water card.

[0042] It is recommended to use a plug-in card reader. The water card can only be dispensed after the user resets the water gun 5, removes the water bucket, and closes the main door 3 or the side door 4.
