Description

Technical Field

[0001] This utility model relates to the field of direct drinking water machines, and in particular to a campus direct drinking water machine with a highly efficient sterilization function. Background Technology

[0002] In a school environment, drinking fountains are essential for ensuring convenient access to drinking water for teachers and students. However, current drinking fountains on the market have a number of significant problems. In scenarios where multiple taps are turned on simultaneously, insufficient water supply often occurs due to limited water supply capacity, failing to meet the needs of teachers and students. Furthermore, existing drinking fountains use relatively simple sterilization methods, making it difficult to thoroughly remove bacteria, viruses, and other microscopic impurities from the water, thus failing to adequately guarantee the quality and safety of drinking water. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a campus drinking water machine with a highly efficient sterilization function, so as to solve the problems of high bacterial infection rate, insufficient water supply from multiple faucets at the same time, and incomplete sterilization in existing campus drinking water machines.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] A campus drinking water machine with high-efficiency sterilization function includes a housing. The housing (1) is equipped with a filtration system for external water source, a heat exchanger (2), a hot water tank (3), and a range extender (4). The outlet of the filtration system is connected to the cold fluid inlet of the heat exchanger. The cold fluid outlet of the heat exchanger is connected to the hot water tank. The outlet of the hot water tank is connected to the hot fluid inlet of the heat exchanger. The hot fluid outlet of the heat exchanger is connected to the range extender. A flow-through UV sterilization lamp is provided on the pipeline between the heat exchanger and the range extender.

[0006] Preferably, the filtration system includes, in sequence, a first-stage filter cotton adsorption device, a second-stage activated carbon adsorption device, a third-stage filter cotton adsorption device, an RO membrane purification device, and a post-activated carbon adsorption device. The first-stage filter cotton adsorption device consists of two filter elements connected in parallel, and the filter elements are 5-micron PP cotton filter elements. The filter elements of the third-stage filter cotton adsorption device are 1-micron PP cotton filter elements.

[0007] Preferably, the extended-range water tank includes four faucets connected to its outer wall, two opposing UV sterilization lamps are built into both sides of the extended-range water tank, a heating rod for heat preservation is built into the extended-range water tank, and a silver ion layer is attached to the spout of each of the faucets.

[0008] Compared with the prior art, the advantages of this utility model are as follows:

[0009] 1. In terms of sterilization, this utility model achieves efficient sterilization through the coordinated operation of multiple parts of the direct drinking water machine. The raw water is initially filtered by the filtration system to intercept bacteria and other impurities, completing the first stage of sterilization; the hot water tank heats and boils the water to achieve the second stage of sterilization; the flow-through UV sterilization lamp performs the third stage of sterilization; the extended-range water tank contains a direct-beam UV lamp for the fourth stage of sterilization; and the silver ion layer at the water tap completes the final sterilization. These designs form a complete sterilization system that comprehensively and efficiently kills microorganisms in the water, ensuring the safety and hygiene of drinking water and protecting the health of teachers and students.

[0010] 2. This utility model improves the water supply stability when multiple people use water by designing an extended-range water tank. Traditional direct drinking water machines are prone to insufficient water supply when multiple taps are turned on at the same time. However, this extended-range water tank has a large water storage space and multiple external water outlets that can connect to multiple taps. When teachers and students on campus use water in a concentrated manner, it can provide a stable water supply, avoid the inconvenience of insufficient water supply, and meet the water needs of densely populated places.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 4This embodiment provides a campus drinking water dispenser with high-efficiency sterilization function, including a housing 1. The housing 1 houses a filtration system for an external water source, a heat exchanger 2, a heating tank 3, and a range extender tank 4. The entire drinking water dispenser is enclosed by the housing 1, which not only protects the internal components but also provides a stable support structure for the entire device. Inside the housing 1, the filtration system and the heating tank 3 are installed on the left and right sides of the bottom plate. The heat exchanger 2 is located in the middle of the housing, corresponding to the water receiving area. The range extender tank 4 is fixedly installed inside the housing near the top plate. All components are arranged in an orderly manner, working together to achieve the drinking water dispenser's high-efficiency sterilization and stable water supply functions.

[0018] The hot tank 3 is the tank for heating water in traditional technology. It achieves the function of boiling water by arranging electric heating rods on the inside of the tank. This is a mature technology and will not be described in detail here.

[0019] The filtration system includes, in sequence, a first-stage filter cotton adsorption device 5, a second-stage activated carbon adsorption device 6, a third-stage filter cotton adsorption device 7, an RO membrane purification device 8, and a post-activated carbon adsorption device 9. The first-stage filter cotton adsorption device 5 consists of two filter elements connected in parallel to obtain a larger filtration flow rate. The filter element is a 5-micron PP cotton filter element. The filter element of the third-stage filter cotton adsorption device 7 is a 1-micron PP cotton filter element.

[0020] After the raw water enters, it will be initially filtered through the first-stage filter cotton adsorption device. After filtration, it will be adsorbed by the second-stage activated carbon adsorption device to adsorb pigments and odors. Then it will be deeply filtered through the third-stage filter cotton adsorption device. After these three stages of filtration, the water will enter the RO membrane purification device to focus on purifying microscopic impurities such as bacteria and viruses. This is the first stage of sterilization, which achieves the effect of filtration from the water source.

[0021] The outlet of the filtration system is connected to the cold fluid inlet of heat exchanger 2, the cold fluid outlet of heat exchanger 2 is connected to the hot tank 3, the outlet of hot tank 3 is connected to the hot fluid inlet of heat exchanger 2, and the hot fluid outlet of heat exchanger 2 is connected to the range extender tank 4. In order to achieve the effect of direct drinking, the boiled water needs to be cooled down. By using the boiled water to preheat the low-temperature purified water, the two can exchange heat, which not only achieves the effect of cooling the direct drinking water, but also uses heat to heat up the purified water, thereby effectively saving resources. Of course, the boiling water in the hot tank is a high-temperature sterilization, which is the second stage of sterilization, mainly to kill some residual bacteria in the water.

[0022] A flow-through UV sterilization lamp 10 is installed on the pipeline between the heat exchanger 2 and the extended water tank 4. This is a three-stage sterilization process, which sterilizes the drinking water that flows into the extended water tank.

[0023] The extended range water tank 4 has two opposing UV lamps 12 built into its sides, which is the fourth stage of sterilization, further and continuously sterilizing the warm water stored in the extended range water tank 4.

[0024] The extended range water tank 4 has a built-in heating rod for heat preservation (not shown in the figure). The heating rod can be installed horizontally near the bottom of the extended range water tank. The heating rod heats the final drinking water to maintain a constant temperature, ensuring that the water temperature reaches the required temperature when it is dispensed.

[0025] The range extender water tank 4 connects to the four faucets 11 on the outer wall of the machine body. Each faucet 11 has a silver ion layer attached to its water nozzle (not shown in the figure). This is the fifth stage of sterilization. Silver ions can effectively inhibit bacteria present in the water flow by destroying their cell membranes and inactivating the substances inside the cells to carry out the final sterilization effect.

[0026] The design of the extended-range water tank 4 greatly improves the water supply stability of the water purifier in scenarios with multiple users. Traditional water purifiers often suffer from insufficient water supply when multiple taps are turned on at the same time due to limitations in water storage and supply capacity. However, the extended-range water tank 4 of this water purifier has a large water storage space and multiple external water outlets that connect to multiple taps 11. When teachers and students on campus use water in a concentrated manner and multiple taps are turned on at the same time, the extended-range water tank 4 can continuously and stably supply water to each tap, ensuring that each user can obtain sufficient water. This effectively avoids the inconvenience caused by insufficient water supply, greatly improves the user experience, and meets the needs of concentrated water use in densely populated places such as campuses.

[0027] In summary, this invention achieves highly efficient sterilization through the synergistic action of multiple components. After the raw water enters the drinking water machine, it first undergoes multiple filtration stages in the filtration system, removing various impurities and initially intercepting bacteria and viruses, completing the first stage of sterilization. The heating tank heats the water to a boil, using high temperature to kill a large number of bacteria, achieving the second stage of sterilization. Before entering the extended-range water tank 4, the water undergoes a third stage of sterilization using a flow-through UV sterilizing lamp 10, reducing residual bacteria. The UV sterilizing lamps 12, built into both sides of the extended-range water tank 4, comprehensively sterilize the water stored in the tank, ensuring the fourth stage of sterilization. Finally, a silver ion layer is applied to the water spout of the faucet 11, providing a final line of sterilization for the flowing water. This series of multi-part, multi-layered sterilization designs forms a complete closed-loop sterilization system, capable of comprehensively and efficiently killing bacteria, viruses, and other microorganisms in the water, ensuring the safety and hygiene of the drinking water ultimately obtained by users, and providing strong protection for the health of teachers and students on campus.

[0028] In addition, the heating rod inside the range extender tank 4 can maintain the temperature of the warm water buffer tank, and can also be electrically heated to boiling water when necessary to meet the demand for boiling water supply.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
