Description

Technical Field

[0001] This utility model relates to the field of ozone sterilization technology, and in particular to a direct drinking water ozone sterilization device that can prevent water from siphoning in. Background Technology

[0002] With the improvement of people's living standards and the enhancement of health awareness, the demand for direct drinking water is increasing. Direct drinking water systems provide people with convenient, fast, and safe drinking water, and are gradually becoming an indispensable part of modern life. In the development of direct drinking water systems, ensuring the safety and hygiene of water quality has always been a key issue. Ozone has strong oxidizing properties and can quickly destroy the cell membranes and nucleic acid structures of bacteria, viruses, and other microorganisms, thereby achieving the purpose of sterilization and disinfection. Compared with traditional sterilization methods such as chlorine disinfection, ozone sterilization has the advantages of fast sterilization speed, good effect, no residue, and no harmful by-products. It can effectively ensure the microbial safety of direct drinking water and improve the quality of direct drinking water. Therefore, ozone sterilization technology has been widely used in direct drinking water systems and has become one of the important means to ensure the quality of direct drinking water.

[0003] Existing ozone sterilization devices for direct drinking water may experience siphon water ingress during use. Siphon water ingress can cause a series of serious problems. On the one hand, it may re-contaminate the sterilized drinking water, undermining the effectiveness of ozone sterilization and affecting water quality safety. On the other hand, siphon water ingress may also damage the ozone generator, such as causing moisture to get into the ozone generator and other equipment, affecting its normal operation and service life, increasing maintenance costs and the risk of system failure. Therefore, we have launched a new ozone sterilization device for direct drinking water that can prevent siphon water ingress. Utility Model Content

[0004] The main purpose of this invention is to provide a direct drinking water ozone sterilization device that can prevent siphon water ingress, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An ozone sterilization device for direct drinking water that prevents siphoning water ingress includes a base. An ozone generator is fixedly installed on the upper left side of the base, and a purified water tank is fixedly installed on the upper right side of the base. An inlet pipe is fixedly connected to the upper left side of the outer surface of the purified water tank. A mixing pipe is fixedly connected to the left end of the inlet pipe. A connecting cylinder is fixedly connected to the upper part of the outer surface of the mixing pipe. An anti-siphoning mechanism is installed inside the connecting cylinder. A flexible hose is fixedly connected to the upper end of the connecting cylinder. The end of the flexible hose away from the connecting cylinder is fixedly connected to the ozone generator. A connecting pipe is fixedly connected to the left end of the mixing pipe. A connecting seat is fixedly connected to the left end of the connecting pipe. A connecting groove is opened at the left end of the connecting seat. A limit groove is opened at the upper end of the connecting seat. A connecting mechanism is engaged in the connecting groove. A water supply pipe is fixedly connected to the left end of the connecting mechanism.

[0007] Preferably, the anti-siphon mechanism includes a micro motor, the output end of which is fixedly connected to a rotating rod, a sealing block is fixedly connected to the outer surface of the rotating rod, and a sealing ring is fixedly connected to the outer surface of the sealing block.

[0008] Preferably, the micro motor is fixedly installed on the front of the outer surface of the connecting cylinder, and the rear end of the rotating rod is movably connected to the rear wall of the inner surface of the connecting cylinder.

[0009] By adopting the above technical solution, the sealing block can be rotated by driving a micro motor, which can open or close the inside of the connecting cylinder.

[0010] Preferably, the sealing block is located inside the connecting cylinder, and the outer surface of the sealing ring is in close contact with the inner wall of the connecting cylinder.

[0011] By adopting the above technical solution, the inside of the connecting cylinder can be sealed by tightly adhering the sealing ring to the inner wall of the connecting cylinder, thereby avoiding siphoning and preventing water from flowing back into the ozone generator and causing damage to the ozone generator.

[0012] Preferably, the connecting mechanism includes a connecting block, a through connecting channel is provided in the middle of the left end of the connecting block, a sealing gasket is fixedly connected to the right end of the connecting block, a groove is provided in the upper end of the connecting block, a spring is fixedly connected to the lower wall of the groove, and a limit block is fixedly connected to the upper end of the spring.

[0013] Preferably, the left end of the connecting block is fixedly connected to the water supply pipe, and the connecting block is engaged with the connecting groove, and the sealing gasket is tightly fitted to the right wall of the connecting groove.

[0014] By adopting the above technical solution, the sealing gasket is tightly attached to the right wall of the connecting groove, which can improve the connection sealing performance.

[0015] Preferably, the lower part of the limiting block is movably connected to the groove, and the upper part of the limiting block is engaged with the limiting groove.

[0016] By adopting the above technical solution, the limiting block automatically pops out of the limiting groove under the elastic force of the spring, so that the external water supply pipe can be quickly connected.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up an anti-siphon mechanism, water is sent into the mixing pipe through the water supply pipe and the connecting pipe. At the same time, the ozone generator is started. The ozone generator sends ozone into the mixing pipe through the hose to mix with the water to form ozone water. This ozone water is then sent into the purified water tank through the water inlet pipe to sterilize the water in the purified water tank. After the ozone is added, the micro motor is started. The micro motor drives the rotating rod to rotate, which in turn drives the sealing block to rotate. This makes the sealing ring tightly adhere to the inner wall of the connecting cylinder, thus sealing the inside of the connecting cylinder and preventing siphoning. This prevents water from flowing back into the ozone generator and damaging it, and extends the service life of the ozone generator.

[0019] 2. By setting up a connecting mechanism, pressing down on the limiting block moves it into the groove and compresses the spring. Then, the connecting block is inserted into the connecting groove. The limiting block automatically pops out of the limiting groove under the spring force, and the sealing gasket is tightly attached to the right wall of the connecting groove, allowing the external water supply pipe to be quickly connected. Traditional external water supply pipes are generally connected by bolts. Threaded connections require precise alignment and tightening of the external thread of the water supply pipe with the internal thread of the purified water tank interface. Precisely aligning the threads and starting to tighten is difficult and time-consuming, increasing the difficulty and workload of installation. When the purified water tank needs to be repaired or replaced, disassembling the threaded connection may become difficult due to rust, corrosion, or tight meshing of the threads caused by long-term use. Compared with the traditional threaded connection method, the external water supply pipe connection is simpler and more convenient, and it is also easier to disassemble later.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] An ozone sterilization device for direct drinking water that prevents siphoning water intake includes a base 1. An ozone generator 2 is fixedly installed on the upper left side of the base 1. A purified water tank 3 is fixedly installed on the upper right side of the base 1. An inlet pipe 4 is fixedly connected to the upper left side of the outer surface of the purified water tank 3. A mixing pipe 5 is fixedly connected to the left end of the inlet pipe 4. A connecting cylinder 6 is fixedly connected to the upper part of the outer surface of the mixing pipe 5. An anti-siphoning mechanism 7 is installed inside the connecting cylinder 6. A flexible hose 8 is fixedly connected to the upper end of the connecting cylinder 6. The end of the flexible hose 8 away from the connecting cylinder 6 is fixedly connected to the ozone generator 2. A connecting pipe 9 is fixedly connected to the left end of the mixing pipe 5. A connecting seat 10 is fixedly connected to the left end of the connecting pipe 9. A connecting groove 11 is opened on the left end of the connecting seat 10. A limiting groove 12 is opened on the upper end of the connecting seat 10. A connecting mechanism 13 is engaged and connected in the connecting groove 11. A water supply pipe 14 is fixedly connected to the left end of the connecting mechanism 13.

[0030] In this embodiment, the anti-siphon mechanism 7 includes a micro motor 71, the output end of which is fixedly connected to a rotating rod 72, a sealing block 73 is fixedly connected to the outer surface of the rotating rod 72, and a sealing ring 74 is fixedly connected to the outer surface of the sealing block 73. The micro motor 71 is fixedly installed on the front of the outer surface of the connecting cylinder 6, the rear end of the rotating rod 72 is movably connected to the inner rear wall of the connecting cylinder 6, the sealing block 73 is located inside the connecting cylinder 6, and the outer surface of the sealing ring 74 is tightly fitted to the inner wall of the connecting cylinder 6.

[0031] The above solution works as follows: After ozone is released, the micro motor 71 is activated, which drives the rotating rod 72 to rotate. The rotating rod 72 then drives the sealing block 73 to rotate, causing the sealing ring 74 to fit tightly against the inner wall of the connecting cylinder 6. This seals the inside of the connecting cylinder 6, preventing siphoning and preventing water from flowing back into the ozone generator 2 and causing it to be damaged.

[0032] In this embodiment, the connecting mechanism 13 includes a connecting block 131. A through connecting channel 132 is provided in the middle of the left end of the connecting block 131. A sealing gasket 133 is fixedly connected to the right end of the connecting block 131. A groove 134 is provided in the upper end of the connecting block 131. A spring 135 is fixedly connected to the lower wall of the groove 134. A limit block 136 is fixedly connected to the upper end of the spring 135. The left end of the connecting block 131 is fixedly connected to the water supply pipe 14, and the connecting block 131 is engaged with the connecting groove 11. The sealing gasket 133 is tightly fitted with the right wall of the connecting groove 11. The lower part of the limit block 136 is movably connected to the groove 134, and the upper part of the limit block 136 is engaged with the limit groove 12.

[0033] The above solution involves pressing down on the limiting block 136, causing it to move into the groove 134 and compress the spring 135. Then, the connecting block 131 is inserted into the connecting groove 11. Under the elastic force of the spring 135, the limiting block 136 automatically pops out of the limiting groove 12, and the sealing gasket 133 is tightly attached to the right wall of the connecting groove 11, allowing the external water supply pipe 14 to be quickly connected.

[0034] It should be noted that this utility model is a direct drinking water ozone sterilization device that can prevent siphon water ingress. During use, by pressing down on the limiting block 136, it moves deeper into the groove 134 and compresses the internal spring 135. Then, the connecting block 131 is inserted into the connecting groove 11. At this time, the compressed spring 135 will use its elastic force to push the limiting block 136 to automatically pop out of the limiting groove 12. At the same time, the sealing gasket 133 will also fit tightly against the right groove wall of the connecting groove 11, which provides convenience for the quick connection of the external water supply pipe 14. Compared with the traditional method of using bolts to connect the external water supply pipe 14, this method avoids the tedious and precise alignment and tightening operation of the external thread of the water supply pipe 14 with the internal thread of the purified water tank 3 interface. The traditional threaded connection method is not only difficult to align, but also time-consuming and laborious in the tightening process, which increases the difficulty and workload of installation, especially when the purified water tank 3 needs to be repaired or replaced. When replacing the thread, long-used threads may become difficult to disassemble due to rust, corrosion, or tight meshing. However, with this new connection method, the connection of the external water supply pipe 14 becomes simple and quick, and it also facilitates subsequent disassembly. Once the external water supply pipe 14 is connected, water will be sent into the mixing pipe 5 through the water supply pipe 14 and the connecting pipe 9. At this time, the ozone generator 2 is started, and ozone will be sent into the mixing pipe 5 through the hose 8 to mix with the water to form ozone water. This ozone water is then sent into the purified water tank 3 through the inlet pipe 4 to sterilize the water. After the ozone is released, the micro motor 71 is started. The micro motor 71 will drive the rotating rod 72 to rotate, which in turn will drive the sealing block 73 to rotate. At this time, the sealing ring 74 will tightly fit against the inner wall of the connecting cylinder 6, effectively sealing the inside of the connecting cylinder 6, thereby preventing siphoning and avoiding water backflow into the ozone generator 2, which could damage the equipment and further extend the service life of the ozone generator 2.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
