Description

Technical Field

[0001] This utility model relates to the field of water supply equipment technology, and in particular to a water storage tank for a water supply equipment with a filtration mechanism. Background Technology

[0002] Water storage tanks with filtration systems are crucial for ensuring water quality and safety, and are widely used in residential buildings, commercial buildings, industrial plants, and other scenarios requiring a safe and stable water supply. They bear the important responsibility of storing water and performing preliminary filtration, ensuring that the water entering the system has as few impurities as possible, providing reliable water support for people's lives and production activities. Current practical applications typically require the following technologies:

[0003] 1. High-efficiency filtration technology enables the filter components to effectively intercept various impurities in the water, ensuring the cleanliness of the water source;

[0004] 2. Reliable sealing technology prevents external pollutants from entering the water storage space through the inlet pipe, tank gaps, etc., ensuring that the water quality is not contaminated;

[0005] 3. Adaptive connection technology ensures a stable and well-sealed connection between the inlet pipe, outlet pipe and the water storage tank, facilitating the smooth entry and exit of water sources;

[0006] 4. The robust tank structure design technology enables the water storage tank to withstand a certain pressure, ensuring safety and stability during storage and water supply.

[0007] 5. Convenient maintenance technology, so that it is easy to repair and replace when filter components or other parts malfunction.

[0008] Currently, various devices and methods are used to achieve the filtration and storage functions of water storage tanks. Some tanks have a simple mesh filter structure at the inlet pipe to intercept larger particles. Others use a design with a filter cartridge installed inside the inlet pipe, relying on the fine pores within the cartridge to perform fine filtration of the water. Some tanks are also equipped with removable filter components for easy periodic removal, cleaning, or replacement.

[0009] However, the above method has a prominent problem: the filter cartridge lacks a pop-out removal function. When the filter cartridge has been used for a long time and a lot of impurities have accumulated on its surface, requiring cleaning and maintenance, it is difficult for staff to easily remove the filter cartridge. Conventional removal methods often require the use of tools to reach deep into the water inlet pipe. The operating space is narrow, which is not only extremely inconvenient to operate, but may also damage the filter cartridge and water inlet pipe due to improper operation, affecting the filtration effect and the sealing of the water storage tank, increasing maintenance costs and the risk of water pollution. Utility Model Content

[0010] To address the shortcomings of existing technologies, this utility model provides a water storage tank for a water supply device with a filtration mechanism. This solves the problem of the filter cartridge lacking a pop-out and removable function. When the filter cartridge has been used for a long time and a large amount of impurities have accumulated on its surface, requiring cleaning and maintenance, it is difficult for staff to easily remove the filter cartridge. Conventional removal methods often require tools to be inserted into the water inlet pipe, which results in a narrow operating space. This is not only extremely inconvenient to operate, but may also damage the filter cartridge and water inlet pipe due to improper operation, affecting the filtration effect and the sealing of the water storage tank, increasing maintenance costs and the risk of water pollution.

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] A water storage tank for a water supply device with a filtration mechanism includes a tank body. An inlet pipe is fixedly connected to the upper end of the tank body. An elastic mechanism for ejection and removal is provided inside the inlet pipe. The elastic mechanism includes a lifting spring and a filter cylinder. The lifting spring is fixedly connected to the inner surface of the inlet pipe, and the filter cylinder is slidably connected inside the inlet pipe. The lifting spring is sleeved on the outer surface of the filter cylinder. A locking mechanism for sliding limit is provided on the outer surface of the filter cylinder. The locking mechanism includes a locking spring and an inclined locking block. The locking spring is fixedly connected to the outer surface of the filter cylinder, and the inclined locking block is slidably connected to the outer surface of the filter cylinder.

[0013] Preferably, the snap-fit ​​spring is fixedly connected to the outer surface of the inclined snap-fit ​​block, and a snap-fit ​​groove is provided inside the water inlet pipe.

[0014] Preferably, the inclined snap-fit ​​block is snapped into the slot, and the outer surface of the filter cylinder is fixedly connected to a limit slider.

[0015] Preferably, the inclined snap-fit ​​block is slidably connected to the outer surface of the limiting slider, and the upper end of the water inlet pipe is fixedly connected with a directional arrow mark.

[0016] Preferably, the directional arrow mark has an arc-shaped positioning groove inside, and a sealing ring is provided inside the arc-shaped positioning groove.

[0017] Preferably, the upper end of the water inlet pipe is provided with a sealing cap, and the sealing ring is sleeved on the inner surface of the sealing cap.

[0018] Preferably, a device base is fixedly connected to the lower end of the water storage tank body, and a water pump is fixedly connected to the upper end of the device base.

[0019] Preferably, both the water storage tank body and the water pump are equipped with liquid delivery pipes, and a water supply connection pipe is fixedly connected to the end of the water pump's outer surface away from the water storage tank body.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. As the filter cartridge is used for a long time, impurities will accumulate on its surface. At this time, the filter cartridge needs to be removed for cleaning and maintenance. The staff should press the exposed surfaces of the two inclined locking blocks with both hands to disengage the inclined locking blocks from the slots and release the locking limit on the filter cartridge. At this time, the previously contracted and stored lifting spring releases its elasticity and pops the filter cartridge upward, making it easy for the staff to remove. There is no need to reach into the water inlet pipe to retrieve it. The operation is simple and convenient.

[0022] 2. Before installing the sealing cap, first align the sealing ring with the arc positioning groove marked by the arrow at the top of the water inlet pipe. The arrow marks not only guide the installation of the filter cartridge, but also provide a convenient positioning effect for the sealing ring. Attached Figure Description

Detailed Implementation

[0031] This application provides a water storage tank for a water supply device with a filtration mechanism, effectively solving the problem of the lack of a pop-out and removable function for the filter cartridge. When the filter cartridge has been used for a long time and a large amount of impurities have accumulated on its surface, requiring cleaning and maintenance, it is difficult for staff to easily remove the filter cartridge. Conventional removal methods often require tools to be inserted into the inlet pipe, resulting in a narrow operating space. This is not only extremely inconvenient but may also damage the filter cartridge and inlet pipe due to improper operation, affecting the filtration effect and the sealing of the water storage tank, increasing maintenance costs and the risk of water pollution. As the filter cartridge is used for a long time, impurities will accumulate on its surface. At this time, it is necessary to remove the filter cartridge for cleaning and maintenance. The staff can press the exposed surfaces of the two inclined locking blocks with both hands to disengage the inclined locking blocks from the slots, releasing the locking limit on the filter cartridge. At this time, the previously contracted and stored lifting spring releases its elasticity, popping the filter cartridge upwards, making it easy for the staff to remove without having to reach into the inlet pipe. The operation is simple and convenient.

[0032] Example

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the technical solution in this application embodiment effectively solves the problem that the filter cartridge lacks a pop-out retrieval function. When the filter cartridge has been used for a long time and a large amount of impurities adhere to its surface, requiring cleaning and maintenance, it is difficult for workers to easily remove the filter cartridge. Conventional removal methods often require tools to be inserted deep into the water inlet pipe, resulting in a narrow operating space. This is not only extremely inconvenient but may also damage the filter cartridge and water inlet pipe due to improper operation, affecting the filtration effect and the sealing of the water storage tank, increasing maintenance costs and the risk of water pollution. The overall idea is as follows: A water storage tank for a water supply device with a filtration mechanism includes a water storage tank body 11. A water inlet pipe 12 is fixedly connected to the upper end of the water storage tank body 11. An elastic mechanism for popping out and retrieving is provided inside the water inlet pipe 12. The mechanism includes a lifting spring 13 and a filter cylinder 14. The lifting spring 13 is fixedly connected to the inner surface of the water inlet pipe 12, and the filter cylinder 14 is slidably connected inside the water inlet pipe 12. The lifting spring 13 is sleeved on the outer surface of the filter cylinder 14. The outer surface of the filter cylinder 14 is provided with a sliding limit locking mechanism, which includes a locking spring 15 and an inclined locking block 16. The locking spring 15 is fixedly connected to the outer surface of the filter cylinder 14, and the inclined locking block 16 is slidably connected to the outer surface of the filter cylinder 14. The locking spring 15 is fixedly connected to the outer surface of the inclined locking block 16. A locking groove 17 is opened inside the water inlet pipe 12, and the inclined locking block 16 is locked inside the locking groove 17. A limit slider 18 is fixedly connected to the outer surface of the filter cylinder 14, and the inclined locking block 16 is slidably connected to the limit slider 18. 8. On the outer surface, align the water injection pipe with the water inlet pipe 12. The water injection pipe injects water into the water storage tank body 11 through the water inlet pipe 12. The water is stored in the water storage tank body 11. During the water injection operation, the water will be filtered through the filter cylinder 14. The small pores inside the filter cylinder 14 will block and filter impurities carried in the water. When installing the filter cylinder 14, align the arrow at the upper end of the filter cylinder 14 with the pointing arrow mark 19 on the water inlet pipe 12, and slide the filter cylinder 14 into the water inlet pipe 12. During the sliding process, the inner surface of the water inlet pipe 12 will press the inclined surface of the lower end of the inclined locking block 16 on the surface of the filter cylinder 14, thereby centering and pressing the two inclined locking blocks 16 sliding on both sides of the filter cylinder 14. Continue to slide and press the filter cylinder 14. When the filter cartridge 14 slides, it engages with the lifting spring 13 via a circumferential pin on its surface. During sliding, the lifting spring 13 is compressed and compressed to store force, preparing for the lifting operation. After the filter cartridge 14 is inserted into place, the inclined locking block 16 aligns with the slot 17 opened inside the water inlet pipe 12. The locking spring 15 pushes the inclined locking block 16 to engage with the surface of the slot 17, thereby limiting the position of the filter cartridge 14 and ensuring its stable placement. After prolonged use, a certain amount of impurities will accumulate on the surface of the filter cartridge 14. At this time, the filter cartridge 14 needs to be removed for cleaning and maintenance. During cleaning and maintenance, the operator presses the exposed surfaces of the two inclined locking blocks 16 with both hands, causing the filter cartridge 14 to lose the locking and limiting effect of the inclined locking blocks 16.At this point, the charged lifting spring 13 will pop the filter cylinder 14 upwards, allowing operators to easily remove it for maintenance without having to reach into the inlet pipe 12. The operation is simple and convenient.

[0034] A directional arrow marker 19 is fixedly connected to the upper end of the water inlet pipe 12. An arc-shaped positioning groove 21 is formed inside the directional arrow marker 19, and a sealing ring 22 is installed inside the arc-shaped positioning groove 21. A sealing cap 23 is installed at the upper end of the water inlet pipe 12, and the sealing ring 22 is fitted onto the inner surface of the sealing cap 23. During water storage operations, the sealing cap 23 needs to be installed to cover the inlet of the water inlet pipe 12 to prevent dust from entering the water source and causing contamination. Both the sealing cap 23 and the water inlet pipe 12 are flanges, and they are connected and fixed by tightening bolts. The directional arrow mark 19 connected to the upper end of the water inlet pipe 12 has an arc-shaped positioning groove 21. Before installing the sealing cover 23, the sealing ring 22 is aligned and inserted into the arc-shaped positioning groove 21. The directional arrow mark 19 not only serves as a guide for the filter cartridge 14, but also provides a convenient positioning effect for the installation of the sealing ring 22. At this time, the sealing cover 23 is aligned with the water inlet pipe 12, and the sealing ring 22 can be fitted into the arc-shaped groove in the sealing cover 23. The sealing ring 22 fills the connection gap, ensuring the sealing of the water inlet pipe 12 during storage.

[0035] A base 24 is fixedly connected to the lower end of the water storage tank body 11, and a water pump 25 is fixedly connected to the upper end of the base 24. Both the water storage tank body 11 and the water pump 25 are equipped with liquid delivery pipes 26. A water supply connection pipe 27 is fixedly connected to the end of the water pump 25 away from the water storage tank body 11. The water stored in the water storage tank body 11 can be extracted by starting the water pump 25. The water storage tank body 11 and the water pump 25 are connected by the liquid delivery pipe 26 to provide space for the movement of the water source. After the water pump 25 extracts the water source, it supplies the water source through the water supply connection pipe 27 to achieve the purpose of water supply.

[0036] To address the problems existing in the prior art, this utility model provides a water storage tank for a water supply device with a filtration mechanism. As the filter cylinder 14 is used for a long time, impurities will accumulate on its surface. At this time, the filter cylinder 14 needs to be removed for cleaning and maintenance. The operator presses the exposed surfaces of the two inclined locking blocks 16 with both hands to disengage the inclined locking blocks 16 from the locking groove 17, thereby releasing the locking limit on the filter cylinder 14. At this time, the previously contracted and stored lifting spring 13 releases its elastic force and pops the filter cylinder 14 upward, making it easy for the operator to remove. There is no need to reach into the water inlet pipe 12 to retrieve it, making the operation simple and convenient.

[0037] Working principle:

[0038] The first step involves installing a water pump 25 on a device base 24 fixedly connected to the lower end of the water storage tank body 11. The water storage tank body 11 and the water pump 25 are connected through a liquid delivery pipe 26. When water supply is required, the water pump 25 is started, and the water stored in the water storage tank body 11 is drawn out through the liquid delivery pipe 26 under the action of the water pump 25. Then, the water is supplied through the water supply connection pipe 27 fixedly connected to the outer surface of the water pump 25 away from the water storage tank body 11, thus achieving the purpose of water supply. When the water injection pipe is aligned with the water inlet pipe 12 to inject water into the water storage tank body 11, the water passes through the filter cylinder 14. The small holes in the filter cylinder 14 play a role in blocking and filtering impurities carried in the water, thus achieving preliminary filtration of the water entering the water storage tank.

[0039] The second step is to install the filter cartridge 14. Align the arrow at the top of the filter cartridge 14 with the directional arrow mark 19 on the inlet pipe 12, and then slide the filter cartridge 14 along the inlet pipe 12. During the sliding process, the inner surface of the inlet pipe 12 presses against the inclined surface at the lower end of the inclined locking block 16 on the surface of the filter cartridge 14, causing the two inclined locking blocks 16 to press towards the middle. At the same time, the filter cartridge 14 is connected to the lifting spring 13 through the circumferential pin on its surface, and the lifting spring 13 is compressed to contract and store force. After the filter cartridge 14 is inserted into place, the inclined locking block 16 aligns with the slot 17 inside the water inlet pipe 12. The locking spring 15 pushes the inclined locking block 16 into the slot 17, thereby limiting the position of the filter cartridge 14 and ensuring its stable placement inside the water inlet pipe 12. With prolonged use, impurities will accumulate on the surface of the filter cartridge 14. At this time, the filter cartridge 14 needs to be removed for cleaning and maintenance. The operator presses the exposed surfaces of the two inclined locking blocks 16 with both hands to disengage them. Once the filter cartridge 14 is released from the slot 17, the previously compressed lifting spring 13 releases its force, ejecting the filter cartridge 14 upwards for easy removal by staff. This eliminates the need to reach into the inlet pipe 12, making the operation simple and convenient. During water storage, to prevent dust from entering and contaminating the water source, a sealing cap 23 is installed to cover the inlet of the inlet pipe 12. Both the inlet pipe 12 and the sealing cap 23 are flange structures, connected by tightening bolts. Before installing the sealing cap 23, first align the sealing ring 22 and insert it into the arc positioning groove 21 opened in the arrow mark 19 at the upper end of the water inlet pipe 12. The arrow mark 19 serves as a guide for the installation of the filter cartridge 14 and also provides a convenient positioning effect for the sealing ring 22. After aligning the sealing cap 23 with the water inlet pipe 12, the sealing ring 22 is fitted into the arc groove in the sealing cap 23 to fill the gap between the two, thereby ensuring the sealing of the water inlet pipe 12 during water storage.

[0040] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
