Abstract
Description
Technical Field
[0001] This utility model relates to the field of water dispenser sterilization, and more particularly to a water dispenser circulating water sterilization device. Background Technology
[0002] Water dispenser circulating water sterilization mainly kills bacteria, viruses and other microorganisms in the water through physical or chemical methods. Common methods include ultraviolet light using the UV-C band to destroy microbial DNA, ozone's strong oxidizing properties to destroy cell structure, silver ion antibacterial properties, or built-in filter cartridges. Some high-end models also use high-temperature circulating sterilization or electrolytic sterilization technology to ensure the hygiene and safety of drinking water.
[0003] Due to prolonged use, water dispensers are prone to developing a sticky biofilm on the inner wall of the water tank, formed by bacteria, fungi, and microbial secretions. This biofilm is dense and highly adhesive, making it difficult to completely remove with conventional physical rinsing or brief sterilization. Even with high-temperature sterilization, it may not be completely eradicated due to residues in dead corners or uneven temperatures, ultimately affecting water quality safety. Deep cleaning or strong cleaning agents are required, increasing maintenance difficulty and cost.
[0004] Therefore, in response to the problem that due to long-term use, the inner wall of the water tank of the aforementioned water dispenser is prone to the growth of a sticky biofilm formed by bacteria, fungi and microbial secretions. This biofilm has a dense structure and strong adhesion, and conventional physical rinsing or short-term sterilization is difficult to completely remove, ultimately affecting water quality safety. It requires deep disassembly and cleaning or strong cleaning agents, which increases the difficulty and cost of maintenance. Therefore, a water dispenser circulating water sterilization device can be designed. Utility Model Content
[0005] To address the issue that water dispensers, due to prolonged use, easily develop a sticky biofilm on the inner wall of the water tank, formed by bacteria, fungi, and microbial secretions. This biofilm has a dense structure and strong adhesion, making it difficult to completely remove with conventional physical rinsing or brief sterilization, ultimately affecting water quality safety. Therefore, deep disassembly and cleaning or strong cleaning agents are required, which increases the difficulty and cost of maintenance.
[0006] The technical solution of this utility model is as follows: a water dispenser circulating water sterilization device, including a water dispenser body; and a cleaning frame. A water storage tank and a hot water tank are installed inside the water dispenser body. A first cleaning frame is slidably connected inside the water storage tank, and a second cleaning frame is slidably connected inside the hot water tank. A second moving rod is fixedly connected to the bottom of the second cleaning frame, and a first moving rod is fixedly connected to the bottom of the first cleaning frame. An electric cylinder is installed inside the water dispenser body, and a connecting rod is fixedly connected to the output end of the electric cylinder. The electric cylinder is used to drive the connecting rod to move up and down. The connecting rod is fixedly connected to the first moving rod and the second moving rod.

[0007] Preferably, during daily use, the sterilization lamps inside the water storage tank and hot water tank disinfect the drinking water. At the same time, the electric cylinder drives the connecting rod to move up and down, causing the first and second moving rods to drive the first and second cleaning frames to slide up and down on the inner wall of the water tank. This effectively removes potential biofilm and prevents the accumulation of bacteria, fungi, and microbial secretions, thereby avoiding the formation of a dense and highly adhesive slimy biofilm. This solves the problem that traditional water dispensers are difficult to thoroughly clean after long-term use due to routine rinsing or brief sterilization. It not only improves water quality safety but also reduces maintenance difficulty and cost.
[0008] Preferably, a heating plate is fixedly connected to the bottom of the hot water tank, and two slide rails are fixedly connected to the inside of the water dispenser body.
[0009] Preferably, a slider is slidably connected to the inner side of the slide rail, and the slider is fixedly connected to the water storage tank and the hot water tank.
[0010] Preferably, a water tank is movably connected to the upper part of the water dispenser body, and a water pump is installed inside the water dispenser body.
[0011] Preferably, the rear end of the slide rail is movably connected to a limit block, and a filter plate is provided at the front end of the water dispenser body.
[0012] Preferably, a water collection box is movably connected inside the water dispenser body, and a fixing plate is fixedly connected inside the water dispenser body.
[0013] Preferably, the water collection box is movably connected to the fixing plate, and a limit plate is provided at the rear end of the fixing plate.
[0014] The beneficial effects of this utility model are:
[0015] During daily use, the sterilization lamps in the water storage tank and hot water tank disinfect the drinking water. At the same time, the electric cylinder drives the connecting rod to move up and down, causing the first and second moving rods to drive the first and second cleaning frames to slide up and down on the inner wall of the water tank. This effectively removes potential biofilm and prevents the accumulation of bacteria, fungi, and microbial secretions, thus avoiding the formation of a dense and highly adhesive biofilm. This solves the problem that traditional water dispensers are difficult to clean thoroughly after long-term use due to routine rinsing or brief sterilization. It improves water quality safety and reduces maintenance difficulty and cost. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-3 This utility model provides an embodiment: a water dispenser circulating water sterilization device includes a water dispenser body 1; it also includes a cleaning frame. A water storage tank 2 and a hot water tank 3 are disposed inside the water dispenser body 1. A first cleaning frame 5 is slidably connected inside the water storage tank 2, and a second cleaning frame 7 is slidably connected inside the hot water tank 3. A second moving rod 8 is fixedly connected to the bottom of the second cleaning frame 7, and a first moving rod 4 is fixedly connected to the bottom of the first cleaning frame 5. An electric cylinder 9 is disposed inside the water dispenser body 1, and a connecting rod 6 is fixedly connected to the output end of the electric cylinder 9. The electric cylinder 9 is used to drive the connecting rod 6 to move up and down. The connecting rod 6 is fixedly connected to the first moving rod 4 and the second moving rod 8. Next, a sterilization lamp 10 is fixedly connected inside the water storage tank 2, and the same sterilization lamp 10 is fixedly connected inside the hot water tank 3. During daily use, the sterilization lamps 10 in the water storage tank 2 and the hot water tank 3 disinfect the drinking water. At the same time, the electric cylinder 9 drives the connecting rod 6 to move up and down, so that the moving rod 1 4 and the moving rod 2 8 drive the cleaning frame 1 5 and the cleaning frame 2 7 to slide up and down on the inner wall of the water tank, effectively removing potential biofilm and preventing the accumulation of bacteria, fungi and microbial secretions. This avoids the formation of a dense and sticky biofilm, solving the problem that traditional water dispensers are difficult to clean thoroughly after long-term use due to routine rinsing or short-term sterilization. This not only improves water quality safety but also reduces maintenance difficulty and cost.
[0024] Please see Figures 1-5In this embodiment, a heating plate 16 is fixedly connected to the bottom of the hot water tank 3, and two slide rails 11 are fixedly connected to the inner side of the water dispenser body 1. The heating plate 16 at the bottom of the hot water tank 3 heats the drinking water in the hot water tank 3. A slider 12 is slidably connected to the inner side of the slide rail 11. The slider 12 is fixedly connected to the water storage tank 2 and the hot water tank 3. When the water storage tank 2 and the hot water tank 3 need to be removed, the water storage tank 2 and the hot water tank 3 are pulled outwards, so that the slider 12 slides on the slide rail 11. A water bucket 13 is movably connected to the upper end of the water dispenser body 1. A water pump 14 is installed inside the water dispenser body 1. The drinking water flows down from the water bucket 13 and enters the water storage tank 2. Then, the water pump 14 is used to pump the drinking water in the water storage tank 2 into the heating tank.
[0025] Please see Figures 2-5 In this embodiment, a limiting block 15 is movably connected to the rear end of the slide rail 11, and a filter plate 17 is provided at the front end of the water dispenser body 1. The limiting block 15 is fixed to the slide rail 11 by bolts to fix the position of the water storage tank 2 and the hot water tank 3. A water collection box 18 is movably connected inside the water dispenser body 1, and a fixing plate 19 is fixedly connected inside the water dispenser body 1. When wastewater is splashed on the water dispenser, the filter plate 17 filters out the impurities in the wastewater, and then the wastewater is collected by the water collection box 18. The water collection box 18 is movably connected to the fixing plate 19. A limiting plate 20 is provided at the rear end of the fixing plate 19, and the water collection box 18 is placed on the fixing plate 19. When it is necessary to remove and clean the water collection box 18, the limiting plate 20 is removed from the fixing plate 19, and then the collection box is removed. During installation, the limiting plate 20 is fixed to the fixing plate 19 by external bolts.
[0026] During operation and daily use, the sterilization lamps 10 inside the water storage tank 2 and hot water tank 3 disinfect the drinking water. Then, the electric cylinder 9 drives the connecting rod 6 to move up and down. The connecting rod 6, along with the moving rod 1 4 and the moving rod 2 8, drives the cleaning frame 1 5 and the cleaning frame 2 7 to move up and down, cleaning the water storage tank 2 and hot water tank 3 to prevent biofilm growth. When it is necessary to remove the water storage tank 2 and hot water tank 3, pull them outwards to allow the slider 12 to slide on the slide rail 11 for removal. During installation, the limit block 15 is fixed to the slide rail 11 with bolts to secure the water storage tank 2. At the location of the hot water tank 3, drinking water flows downward from the water bucket 13 into the water storage tank 2. Then, the water pump 14 pumps the drinking water in the water storage tank 2 into the heating tank. The heating plate 16 at the bottom of the hot water tank 3 heats the drinking water in the hot water tank 3. When wastewater is splashed on the water dispenser, the filter plate 17 filters out the impurities in the wastewater. Then, the wastewater is collected by the collection box. When it is necessary to remove and clean the collection box 18, the limiting plate 20 is removed from the fixing plate 19, and then the collection box is removed. During installation, the limiting plate 20 is fixed to the fixing plate 19 by external bolts.
[0027] Through the above steps, during daily use, the sterilization lamps 10 in the water storage tank 2 and the hot water tank 3 disinfect the drinking water. Then, the electric cylinder 9 drives the connecting rod 6 to move up and down. The connecting rod 6, along with the moving rod 1 4 and the moving rod 2 8, drives the cleaning frame 1 5 and the cleaning frame 2 7 to move up and down, cleaning the water storage tank 2 and the hot water tank 3 to prevent biofilm growth. This solves the problem that due to long-term use, the inner wall of the water tank is prone to the growth of a sticky biofilm formed by bacteria, fungi, and microbial secretions. This biofilm has a dense structure and strong adhesion, and conventional physical rinsing or short-term sterilization is difficult to completely remove, ultimately affecting water quality safety. Deep disassembly and cleaning or strong cleaning agents are required, which increases the difficulty and cost of maintenance.
