[0002] Currently, people have increasingly higher requirements for drinking water quality, and direct drinking water is gradually becoming the mainstream choice. However, existing direct drinking water storage equipment has many problems. On the one hand, most traditional storage containers are made of ordinary materials, such as common plastics, which are easily affected by the environment. Under conditions such as light and high temperature, they may release harmful substances and contaminate the direct drinking water. Moreover, their sealing performance is not good, making it difficult to effectively prevent outside air and impurities from entering, which makes the direct drinking water susceptible to secondary pollution. For example, after repeated use, some plastic water buckets will have scratches on the walls, making it easy for microorganisms to attach and grow. On the other hand, they are not good at maintaining water temperature and cannot adapt to people's diverse needs for water temperature in different seasons and environments. In summer, the high outside temperature can easily raise the temperature of the direct drinking water in the bucket, affecting the taste. In winter, the water temperature will drop rapidly, and if you want to drink warm water, you need to heat it up, which is very inconvenient. Therefore, it is necessary to design a direct drinking water preservation and storage container to solve the above problems. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A direct drinking water preservation and storage container includes a food-grade 316 stainless steel bucket 1. The food-grade 316 stainless steel bucket 1 serves as the main structure of the container, possessing extremely high chemical stability to prevent chemical reactions with the direct drinking water, thus ensuring the purity of the water from the source. The outer side of the food-grade 316 stainless steel bucket 1 is wrapped with a PEF insulation layer 3, which is tightly attached to the outside of the bucket, forming an effective temperature barrier to reduce the impact of external ambient temperature on the drinking water inside. An observation strip window 4 is provided on the side wall of the food-grade 316 stainless steel bucket 1. This allows users to easily monitor the contents of the bucket without opening it, improving usability. The observation strip window 4 and the food-grade 316 stainless steel... The interior of the bucket 1 is interconnected. This interconnected design ensures that the user can see the true state of the drinking water inside the bucket through the observation window 4, guaranteeing the accuracy of the observation results. A bucket tube 5 is connected to the center of the top of the food-grade 316 stainless steel bucket 1. The bucket tube 5, located at the top center, facilitates the use of drinking water and ensures a uniform water flow, preventing spillage. A slot 15 is provided inside the bucket tube 5, providing a precise installation position for the plug post 8 and ensuring a stable connection between the plug post 8 and the bucket tube 5. The inner wall of the food-grade 316 stainless steel bucket 1 is coated with a silver ion coating 6. The silver ion coating 6 directly contacts the drinking water and continuously exerts a bactericidal effect, preventing bacterial growth on the bucket wall. A sealing cap 14 is installed at the end of the bucket tube 5. The tight fit with the end of the tubing 5 immediately blocks external impurities from entering the tub. The outer surface of the sealing cap 14 is wrapped with an outer layer of food-locking film 2, which further enhances the sealing performance and makes the seal last longer. A plug post 8 is fixedly connected to the lower end of the sealing cap 14. This fixed connection ensures synchronized operation, improving the ease of opening and closing the container. Multiple threads 7 are engraved on the upper part of the outer surface of the plug post 8. These threads make the connection between the plug post 8 and the slot 15 inside the tubing 5 tighter and allow for easy manual tightening or loosening by the user. A groove 9 is located in the middle of the lower end of the plug post 8. The size of the groove 9 matches the short locking post 10, firmly securing the short locking post 10 and preventing... During use, the activated carbon rod 12 is wobbly. A short locking post 10 is inserted into the slot 9, allowing for quick connection between the short locking post 10 and the plug post 8 via the slot 9. This facilitates the installation and replacement of the activated carbon rod 12. The lower end of the short locking post 10 is fixedly connected to the activated carbon rod 12. This fixed connection ensures the activated carbon rod 12 remains in a stable position within the container, ensuring full contact with the drinking water. A limiting ring 11 is provided at the connection point between the activated carbon rod 12 and the short locking post 10. The limiting ring 11 restricts the position of the activated carbon rod 12, preventing it from shifting excessively due to gravity or water flow impact. Multiple activated carbon pores 13 are provided around the outer surface of the activated carbon rod 12. These pores increase the contact area between the activated carbon rod 12 and the drinking water, enabling more efficient adsorption of impurities in the water.The PEF insulation layer 3 is completely fitted and wrapped around the outer surface of the food-grade 316 stainless steel drum 1. This complete fit eliminates air gaps between the two, resulting in better insulation. The shape of the PEF insulation layer 3 matches the outer contour of the food-grade 316 stainless steel drum 1, ensuring a perfect fit and preventing any exposed areas that could affect insulation. The top of the PEF insulation layer 3 is flush with the top of the food-grade 316 stainless steel drum 1, and the bottom of the PEF insulation layer 3 extends to the bottom of the food-grade 316 stainless steel drum 1. The bottom edge is designed to fully enclose the food-grade 316 stainless steel drum 1, leaving no dead corners for insulation and improving overall insulation performance. The observation strip window 4 is vertically set along the side wall of the food-grade 316 stainless steel drum 1. This vertically set observation strip window 4 can completely display the water level changes from the bottom to the top of the drum, making it easy for users to monitor different water levels. The observation strip window 4 is 3 cm wide, ensuring a clear field of view without excessively affecting the structural strength of the food-grade 316 stainless steel drum 1. Furthermore, the inner edge of the observation strip window 4 and the silver ion coating 6... The outer surfaces are seamlessly connected. This connection design prevents drinking water from remaining at the junction of the observation window 4 and the container wall, reducing the risk of bacterial growth. The diameter of the sealing cap 14 is larger than that of the container tube 5. This larger diameter allows the sealing cap 14 to completely cover the end of the container tube 5, enhancing the overall sealing. Furthermore, the lower end face of the sealing cap 14 fits snugly against the top face of the container tube 5. This tight fit prevents air from entering through any gaps, ensuring the effectiveness of the seal. The outer layer of food-locking film 2 simultaneously wraps the top of the sealing cap 14 and the upper outer part of the container tube 5, forming a complete seal and preventing single-layer leakage. A leak appeared in the sealing of a portion of the container. The plug 8 is connected to the slot 15 inside the tubing 5 via threads 7. The threaded connection 7 provides good sealing and detachability, allowing users to easily open the container to refill drinking water as needed. The length of the plug 8 is matched to the depth of the slot 15, ensuring that the plug 8 is fully embedded in the slot 15, preventing leaks caused by loose connections. Furthermore, the outer surface of the plug 8 fits tightly against the inner wall of the slot 15, further enhancing the seal between the plug 8 and the slot 15 and preventing drinking water from leaking out.

[0025] In this embodiment, in an office setting, the direct drinking water preservation and storage container can efficiently preserve and store direct drinking water. Staff first prepare the drinking water, then tear off the outer layer of the sealing cap 14 wrapped with the freshness-locking film 2. Next, they rotate the sealing cap 14. Because the upper surface of the plug 8 has multiple threads 7 engraved and connects to the slot 15 inside the tubing 5 via these threads, the plug 8 can be easily removed from the slot 15. At this point, water is injected into the food-grade 316 stainless steel tubing 1 through the tubing 5. Direct drinking water is supplied, and the water level is observed through a 3-cm-wide observation strip 4 vertically along the side wall of the food-grade 316 stainless steel container 1, with its inner edge connecting to the outer surface of the silver ion coating 6. Once the water level is appropriate, water filling is stopped. Then, the plug 8 with the activated carbon rod 12 is reinserted into the slot 15. Since the length of the plug 8 matches the depth of the slot 15 and its outer surface fits tightly against the inner wall of the slot 15, the sealing cap 14 is tightened so that its lower end fits against the top surface of the container tube 5. Then... The outer surface of the sealing cap 14 is re-wrapped with an outer layer of food-locking film 2, which also wraps the top of the sealing cap 14 and the upper outer side of the tubing 5 to enhance the seal. During storage, the PEF insulation layer 3, which completely fits the outside of the food-grade 316 stainless steel tub 1, has a shape consistent with the external contour, a top flush with the top of the tub, and extends to the bottom edge of the tub, effectively insulates against external temperatures and maintains a stable water temperature inside the tub. Meanwhile, the silver ion coating 6 on the inner wall of the food-grade 316 stainless steel tub 1... Continuous sterilization prevents bacterial growth, and the activated carbon rod 12 is inserted into the slot 9 at the lower middle of the plug post 8 via the short locking post 10. The limiting ring 11 at the connection between the short locking post 10 and the activated carbon rod 12 prevents it from moving too far down. Multiple activated carbon holes 13 around the outer surface of the activated carbon rod 12 increase the contact area to absorb odors and impurities and improve the taste. When it is necessary to replace the activated carbon rod 12, open the sealing tube cover 14 according to the above steps, take out the plug post 8, and pull out the short locking post 10 from the slot 9 to replace it. The operation is convenient.

[0026] It should be noted that this utility model is a direct drinking water preservation and storage container. The food-grade 316 stainless steel bucket 1 serves as the main container, providing a stable storage space. The silver ion coating 6 on its inner wall is in direct contact with the direct drinking water, utilizing the bactericidal properties of silver ions to inhibit bacterial growth in the water. The outer PEF insulation cotton layer 3 is completely fitted and its shape is consistent with the outer contour of the bucket, with the top flush and the bottom extending to the bottom edge, effectively blocking external temperature transfer and maintaining a stable water temperature inside the bucket. The observation strip window 4, with a width of 3 cm and an inner edge connecting to the outer surface of the silver ion coating 6, is vertically set on the side wall and communicates with the interior, facilitating the observation of water level and water quality. The bucket tube 5 at the top center and the internal slot 15 provide an installation base for the plug post 8. The plug post 8 is connected to the slot 15 through the thread 7 on the upper part of its outer surface, and its length is adapted to the depth of the slot 15 and its outer surface is... The surface is tightly fitted to the inner wall to ensure a sealed connection and prevent water leakage. The slot 9 at the lower middle part is inserted into the short locking post 10 to fix the activated carbon rod 12. The limiting ring 11 at the connection between the short locking post 10 and the activated carbon rod 12 restricts the position of the activated carbon rod 12 to prevent excessive downward movement. Multiple activated carbon pores 13 on the outer surface of the activated carbon rod 12 increase the contact area with water, adsorb odors and impurities, and improve water quality. The sealing tube cap 14 installed at the end of the barrel tube 5 has a diameter larger than the barrel tube 5 and its lower end face is close to the top face to enhance the sealing effect. The outer layer of freshness-locking film 2 covering its outer surface covers the top of the sealing tube cap 14 and the upper outer side of the barrel tube 5 to further prevent air and impurities from entering. When drinking water is injected, each sealing structure prevents external pollution. The silver ion coating 6 and the activated carbon rod 12 work together to purify the water quality. The PEF heat insulation cotton layer 3 maintains the water temperature, thereby achieving long-term preservation and storage of drinking water.
