Description

Technical Field

[0001] This utility model belongs to the field of water supply equipment technology, specifically relating to an automatic water replenishment device and water-using equipment. Background Technology

[0002] When automated production equipment that consumes water is in operation, a continuous water supply must be provided to ensure the equipment operates normally.

[0003] A production line often includes multiple pieces of equipment. When multiple pieces of equipment are operating at the same time, it is necessary to monitor the water usage in each water tank in real time and supply water to multiple pieces of equipment simultaneously in a timely manner. This is to prevent the water level in the tank from being too low due to untimely water replenishment, which would affect the operation of the equipment, or to prevent excessive water replenishment from causing water to overflow from the tank and be wasted.

[0004] However, existing automatic water replenishment systems are often complex in structure, which not only increases the difficulty of installation and maintenance, but may also affect the stability and reliability of the entire water supply process. Utility Model Content

[0005] This utility model addresses the aforementioned problems in the existing technology by proposing a simple automatic water replenishment device and water-using equipment.

[0006] This utility model can be achieved through the following technical solutions:

[0007] An automatic water replenishment device includes:

[0008] A water storage tank having a first inlet and a first outlet;

[0009] At least two water tanks, each water tank having a second inlet and a second outlet, the second inlet being connected to the first outlet, and the second outlet being used to connect to external equipment;

[0010] A power unit, used to transport water from the water storage tank to each of the water tanks;

[0011] The second water level control valve is installed inside the water tank and automatically controls the opening and closing of the second water inlet according to the water level changes in the water tank.

[0012] As a further improvement to this utility model, it also includes:

[0013] A filtration component configured to connect to an external water source and perform filtration;

[0014] The water delivery component connects the output end of the filter component to the first water inlet, and delivers the filtered water to the water storage tank.

[0015] As a further improvement of this utility model, the power unit is configured as an air supply assembly, which communicates with the inner cavity of the water storage tank through a gas pressurization port opened in the water storage tank, wherein,

[0016] The air supply component fills the water storage tank with gas to create positive pressure, thereby generating a pressure difference between the water storage tank and the water tank, which drives the water in the water storage tank to flow into the water tank.

[0017] As a further improvement of this utility model, the second water level control valve is configured as a second float valve, which is located near the second water inlet. As the water level in the water tank changes, the second float valve automatically opens or closes the second water inlet.

[0018] As a further improvement of this utility model, the water storage tank is provided with a first float valve, which is close to the first water inlet. As the water level in the water storage tank changes, the first float valve automatically opens or closes the first water inlet.

[0019] As a further improvement of this utility model, the air supply component includes:

[0020] An air pump is used to fill the water tank with gas.

[0021] The first pressure sensor monitors the pressure value inside the water storage tank in real time.

[0022] As a further improvement of this utility model, the water tank is equipped with a second pressure sensor, which is used to detect the pressure value inside the water tank in real time.

[0023] As a further improvement of this utility model, the first pressure sensor and the second pressure sensor are respectively connected to the control system signal. The control system adjusts the output power of the air pump based on the pressure difference detected by the first pressure sensor and the second pressure sensor.

[0024] As a further improvement of this utility model, the first water outlet is connected to a main water outlet pipe, and the water outlet end of the main water outlet pipe is connected to the second water inlet of each of the water tanks through a branch water outlet pipe.

[0025] A water-using device is also provided, having the above-mentioned automatic water replenishment device, and further comprising:

[0026] A water pumping assembly, which is connected to the second water outlet, draws water from the water tank and supplies it to various water-consuming components inside the equipment.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. Flexible multi-point water supply and intelligent water level control

[0029] By installing an independent second water level control valve (such as a second float valve) in each water tank, the system can automatically replenish water according to the actual water demand of each water tank, ensuring that the equipment does not interfere with each other and that water is supplied on demand. This design not only improves the flexibility and adaptability of the system, but also effectively prevents equipment failure and water waste caused by abnormal water levels (too low or too high), ensuring production continuity and safe operation of equipment.

[0030] 2. Simplified structure and high energy efficiency

[0031] By replacing the traditional water pump with an air delivery component (air pump + pressure difference drive), the system structure is simplified, the equipment failure rate and maintenance costs are reduced, and the output power of the air pump can be dynamically adjusted to maintain a constant pressure difference, ensuring a smooth and continuous water flow, improving energy efficiency and reducing unnecessary energy consumption and noise.

[0032] 3. Water purification and system reliability improvement

[0033] By configuring a filtration component to purify the raw water and then delivering it to the storage tank via a water delivery component, impurities are effectively prevented from entering the system. This avoids malfunctions such as float valve jamming, pipe blockage, or equipment scaling caused by water quality issues, and extends the service life of the entire water replenishment system.

[0034] 4. Modular piping design and strong expandability

[0035] The water supply network structure of the main outlet pipe and branch outlet pipes is reasonably designed, which facilitates later maintenance, cleaning and functional expansion. This design not only allows the water in the reservoir to be output through a unified main line and then distributed to each water tank according to demand, realizing multi-point synchronous water replenishment, but also allows for flexible connection of more water-using equipment, with strong adaptability and scalability.

[0036] 5. High degree of automation and closed-loop management

[0037] The entire water replenishment device achieves fully automatic water replenishment and pressure regulation through the linkage mechanism of float valve, sensor and control system, without the need for manual monitoring and operation, which greatly reduces operation and maintenance costs. At the same time, the water tank supplies water to the water-consuming components inside the equipment through the water pumping component, and builds a complete closed-loop management system from water source replenishment to actual water use, which enhances the coordination and stability of the whole system and is suitable for various industrial automation scenarios such as humidity testing equipment, cleaning equipment, cooling system, spraying equipment, etc. Attached Figure Description

[0044] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0045] like Figure 1 As shown, this utility model provides an automatic water replenishment device, comprising:

[0046] The water storage tank 100 has a first inlet 110 and a first outlet 120;

[0047] At least two water tanks 200, each water tank 200 having a second inlet 210 and a second outlet 220, the second inlet 210 being connected to a first outlet 120, and the second outlet 220 being used to connect to external equipment.

[0048] A power unit, which is used to transport water from the water storage tank 100 to each water tank 200;

[0049] The second water level control valve is installed inside the water tank 200 and automatically controls the opening and closing of the second water inlet 210 according to the water level changes in the water tank 200.

[0050] The capacity of the water storage tank 100 can be designed according to the actual water demand to ensure that it has sufficient capacity to meet the water demand of external equipment. Each water tank 200 has the capacity to store water so that the water tank 200 can have water stored for external equipment during the time when the water in the water storage tank 100 is not transferred to the water tank 200.

[0051] It should be noted that when multiple external devices are operating simultaneously, it is necessary to monitor the water usage in each water tank 200 in real time and supply water to multiple devices simultaneously in a timely manner to prevent the water level in the water tank 200 from being too low due to untimely water replenishment, which would affect the operation of the equipment, or to prevent excessive water replenishment from causing water to overflow from the water tank 200 and be wasted.

[0052] In this embodiment, during the water supply to external equipment, the water in the water storage tank 100 is continuously output to each water tank 200 through the power unit. At this time, in order to ensure that the water level in each water tank 200 can be maintained within the normal range, a second water level control valve is specially added.

[0053] Specifically, the second water level control valve has a set reference liquid level (i.e. target water level). When the water level in the water tank 200 is lower than the reference liquid level, the second water level control valve automatically opens the corresponding second water inlet 210, so that the water in the storage tank 100 can be continuously transported to the water tank 200.

[0054] When the water level in the water tank 200 is higher than the reference level, the second water level control valve automatically closes the second water inlet 210, thereby cutting off the water inlet passage from the water storage tank 100. At this time, the water in the water storage tank 100 cannot continue to flow into the water tank 200, thus avoiding the overflow caused by excessively high water levels.

[0055] In addition, since each water tank 200 is equipped with an independent second water level control valve, even if multiple water tanks 200 are in different water use states (such as some water tanks 200 are using a large amount of water, while others are fully loaded and on standby), the system can still replenish water as needed and make precise adjustments, thereby ensuring the coordinated operation of the entire water supply system.

[0056] By setting a second water level control valve with a reference liquid level control function, combined with the water supply mechanism of the power unit, this utility model not only solves the problem of uneven water replenishment when multiple devices are operating in parallel, but also achieves efficient, energy-saving, intelligent and stable automatic water replenishment control, and has good application prospects.

[0057] In summary, the automatic water replenishment device provided in this embodiment has at least the following advantages:

[0058] 1. Enables multi-point independent control, improving system flexibility.

[0059] Each water tank 200 is equipped with an independent second water level control valve, which allows different devices to adjust independently according to their own water demand without interfering with each other, significantly improving the flexibility and adaptability of the system operation.

[0060] 2. Prevent equipment malfunctions caused by abnormal water levels.

[0061] The second water level control valve can effectively maintain the water level stability in the water tank 200, preventing external equipment from shutting down or being damaged due to low water level, thus ensuring production continuity and equipment safety.

[0062] 3. Avoid water waste and improve environmental performance.

[0063] By precisely controlling the water replenishment process, overflow problems caused by excessive water replenishment are prevented, thus reducing water waste.

[0064] 4. Achieve automated management and reduce manual intervention.

[0065] The entire water replenishment control mechanism operates automatically without manual intervention, reducing maintenance costs and improving the system's intelligence level.

[0066] 5. Enhance system stability and long-term operational reliability

[0067] The power unit drive, combined with the automatic water level control strategy, makes the entire water replenishment process more stable and orderly, which is conducive to the long-term stable operation of the system and is suitable for the needs of continuous operation in industrial sites.

[0068] Preferred options also include:

[0069] The filter assembly 300 is configured to connect to an external water source and perform filtration. It is used to purify the raw water entering the system, remove impurities, particulate matter and other harmful substances that may affect the operation of the equipment, and obtain pure water.

[0070] The water delivery component 310 connects the output end of the filter component 300 to the first water inlet 110 and is used to deliver the filtered water to the water storage tank 100 to ensure that the water quality entering the water storage tank 100 meets the requirements of subsequent water-using equipment.

[0071] By setting up the filter component 300 and the water supply component 310, the system can effectively prevent impurities from entering the water storage tank and the subsequent water tank 200 during the water replenishment process, avoiding malfunctions such as float valve jamming, pipe blockage or internal scaling of equipment due to water quality problems, thereby improving the stability and service life of the entire water replenishment system.

[0072] Meanwhile, a continuous supply of purified water also helps ensure the normal operation of external equipment, especially suitable for industrial scenarios with high water quality requirements, such as precision cleaning, constant humidity control, or laboratory equipment water.

[0073] The filter assembly 300 may contain a filter membrane with a low mesh size to filter impurities, or the filter assembly 300 may contain a centrifugal assembly to remove impurities by centrifugation.

[0074] Preferably, the power unit is configured as an air supply assembly 400, which communicates with the inner cavity of the water storage tank 100 through a gas pressurization port 130.

[0075] The air supply component 400 fills the water storage tank 100 with gas to create positive pressure, which creates a pressure difference between the water storage tank 100 and the water tank 200. This pressure difference drives the water in the water storage tank 100 to flow into the water tank 200. Under the action of this pressure difference, the water in the water storage tank can automatically flow to each water tank 200 without relying on a water pump, thus achieving a continuous and stable water supply process.

[0076] Using an air supply component 400 as the power unit effectively simplifies the system structure and reduces equipment failure rate and maintenance costs compared to the traditional water supply method driven by a water pump. At the same time, by adjusting the air supply of the air supply component 400, the pressure in the water storage tank can be flexibly controlled, thereby precisely regulating the water supply speed and ensuring that the water level in each water tank 200 is maintained within the set range, avoiding abnormal equipment operation due to untimely or excessive water replenishment.

[0077] Preferably, the second water level control valve is a second float valve 230, which is located near the second water inlet 210. As the water level in the water tank 200 changes, the second float valve 230 automatically opens or closes the second water inlet 210.

[0078] Specifically, when the water level in the water tank 200 drops, the float drops along with the water level. At this time, the second inlet 210 opens, allowing water in the reservoir to flow into the water tank 200 under the action of pressure difference. Conversely, as the water level in the water tank 200 rises to the set reference level, the float blocks the second inlet 210, preventing water from continuing to flow into the water tank 200.

[0079] Based on the characteristic that the float naturally rises and falls with the water level, the second float valve 230 can realize fully automatic opening and closing control of the second inlet 210 without the need for external power drive or complex control system support, which simplifies the overall design and improves the reliability of the system.

[0080] By properly setting the position and action threshold of the float, the water level in the water tank 200 can be precisely controlled to ensure that it is always maintained within an ideal range. This avoids the problem of insufficient water supply to the equipment due to low water level, and also prevents the risk of overflow caused by high water level.

[0081] Similarly, the water storage tank 100 is equipped with a first float valve 140, which is located near the first water inlet 110. As the water level in the water storage tank 100 changes, the first float valve 140 automatically opens or closes the first water inlet 110.

[0082] By setting the first float valve 140, the water level in the water storage tank 100 can always be maintained within the normal range, ensuring that the water demand of external equipment will not be affected by the low water level, and that it will not overflow due to the high water level.

[0083] Preferably, the air supply assembly 400 includes:

[0084] An air pump is used to fill the water storage tank 100 with gas.

[0085] The first pressure sensor 410 monitors the pressure value inside the water storage tank 100 in real time.

[0086] Meanwhile, a second pressure sensor 240 is installed inside the water tank 200. The second pressure sensor 240 is used to detect the pressure value inside the water tank 200 in real time.

[0087] The first pressure sensor 410 and the second pressure sensor 240 establish signal connections with the control system. The control system calculates the actual pressure difference between the water storage tank 100 and the water tank 200 based on the pressure values ​​collected by the two sensors, and dynamically adjusts the output power of the air pump accordingly to achieve precise control of the air supply.

[0088] For example, when the pressure difference is lower than the set threshold, the control system will increase the operating frequency of the air pump and increase the pressure in the water tank 100 to restore normal water supply power; while when the pressure difference is too large, the air pump power will be appropriately reduced to avoid excessive pressurization and energy waste.

[0089] By configuring the first and second air pressure sensors 240 and linking them with the control system, the system can sense the pressure changes between the water storage tank 100 and the water tank 200 in real time, and maintain a constant and appropriate pressure difference by controlling the output power of the air pump, so as to ensure that the water flows continuously and smoothly from the water storage tank 100 to each water tank 200, and avoid the problem of unstable water supply caused by pressure fluctuations.

[0090] Furthermore, this solution is applicable to scenarios where multiple devices with different installation heights and water loads supply water simultaneously, demonstrating strong adaptability and scalability.

[0091] Preferably, the first outlet 120 is connected to the main outlet pipe 500, and the outlet end of the main outlet pipe 500 is connected to the second inlet 210 of each water tank 200 through the branch outlet pipe 510, forming a water supply network structure from the main trunk to the branches. This design allows the water in the reservoir to be output through a unified main line and then distributed to each water tank 200 according to demand, realizing multi-point synchronous water replenishment, meeting the continuous water replenishment needs when multiple external devices are operating in parallel, and significantly improving the water supply efficiency and response speed of the system.

[0092] This utility model also provides a water-using device, which includes the above-mentioned automatic water replenishment device, and further includes:

[0093] The water pumping assembly (not shown in the figure) is connected to the second water outlet 220. The water pumping assembly draws water from the water tank 200 and supplies it to the various water-consuming components inside the equipment.

[0094] By configuring the pumping components, the entire water-using equipment not only has the ability to automatically replenish water, but also can efficiently deliver the replenished water to various water-consuming components, thus constructing a complete water supply system from water storage and replenishment to water use, and improving the overall system's coordination and stability.

[0095] The pumping component can be an independently installed structure or an external device containing other water conveyance power components.
