[0001] The present invention relates to the technical field of water dispensers, and in particular to a direct drinking water purifier with water purification and disinfection functions. Background Art

[0002] As people's living standards continue to improve, they are paying more and more attention to the quality and safety of drinking water, and direct drinking water purifiers have gradually become common appliances in daily life. Traditional direct drinking water purifiers mostly focus only on the purification of raw water, removing impurities, heavy metals, bacteria and other harmful substances in the water through simple filtering devices such as activated carbon filters, ultrafiltration membranes or reverse osmosis membranes to provide relatively pure direct drinking water.

[0003] However, after using the existing direct drinking water purifier filter for a period of time, impurities will accumulate seriously, causing the filter to become clogged, thereby reducing the filtration efficiency and affecting the water flow and water quality. Frequent replacement of the filter is not only costly, but the traditional manual cleaning method is cumbersome and complicated, making it difficult to completely remove the deep dirt inside the filter and unable to fully restore the filter performance.

[0004] In view of this, research and improvement are carried out on the existing problems, and a direct drinking water purifier with water purification and disinfection functions is provided, aiming to solve the problems and improve the practical value through this technology. Summary of the invention

[0018] 3. The present invention increases the internal pressure by delivering steam to the sleeve, pushing the circular plate and the slide block downward, automatically opening the drive valve, and allowing clean water to flow from the clean water tank into the steering pipe, pushing piston B to move, preventing water from entering the bottom of the water pipe. Water flows through the filter element barrel and is discharged from the drainage hole on the outer wall of the cleaning ring. The reaction force causes the cleaning ring to move downward, thereby enhancing the flushing effect of the filter element, removing impurities, improving cleaning efficiency, reducing manual maintenance, and extending the life of the filter element.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The present invention provides a direct drinking water purifier with water purification and disinfection functions, comprising a water dispenser body 1, a smart seat 2 is fixedly installed on the top of the water dispenser body 1, a placement box 3 is arranged below the front of the water dispenser body 1, an air pump 4 is fixedly installed inside the water dispenser body 1, a water storage tank 5 is fixedly installed on the top of the water dispenser body 1, a heating water bladder 6 is arranged below the water storage tank 5, a purification mechanism 7 for purifying water is arranged on one side of the heating water bladder 6, a disinfection mechanism 8 for disinfection is arranged on one side of the water dispenser body 1, and a flushing mechanism 9 for cleaning a filter element is arranged below the water storage tank 5; See also Figures 4 to 6 As shown, the purification mechanism 7 includes a shell 701 installed on the top of the heated water tank 6, the shell 701 is fixedly connected with a connecting sleeve 702 inside, the connecting sleeve 702 is movably connected with a plug 703 inside, the top of the plug 703 is fixedly installed with a spring A704, the top of the shell 701 is fixedly connected with an air pipe A705, one end of the air pipe A705 is fixedly connected with a sleeve 706, the inside of the sleeve 706 is slidably connected with a piston A707, the bottom of the sleeve 706 is fixedly connected with an ozone box 709 through a pipeline, the side wall of the ozone box 709 is fixedly connected with an air pipe B710, one end of the air pipe B710 is fixedly connected with the water storage tank 5, when the heated water tank 6 inside the water dispenser body 1 heats water, steam is generated, and when the steam pressure inside the heated water tank 6 When a certain threshold is reached, the steam will push open the plug 703 inside the shell 701. After the plug 703 is pushed open, the air pump 4 starts and begins to work. The gas generated by the air pump 4 is mixed with the steam generated by the heated water tank 6 and transmitted through the air pipe A705. The mixed gas enters the sleeve 706, increasing the air pressure inside the sleeve 706 and pushing the internal piston A707 to move downward. The movement of the piston A707 compresses the air under the sleeve 706, providing pressure for the ozone inside the ozone box 709, so that it is quantitatively transported through the air pipe B710. The ozone is transported to the water tank 5 through the air pipe B710 to disinfect and purify the pure water in the water tank 5, thereby improving the water purification efficiency. In addition, the safety of the water quality is enhanced through ozone disinfection. See also Figures 7 and 8As shown, the flushing mechanism 9 includes a filter cover 901 installed below the water storage tank 5, a filter cartridge 902 is fixedly installed inside the filter cover 901, a cleaning ring 903 is slidably connected inside the filter cartridge 902, a steering tube 906 is fixedly connected to the bottom of the filter cover 901 through a water pipe 10, a piston B907 is slidably connected inside the steering tube 906, a limit plate 908 is fixedly connected to the inner wall of the steering tube 906 away from the piston B907, the piston B907 and the limit plate 908 are fixedly connected by a spring D909, a driving valve 910 is fixedly connected to one side of the steering tube 906, during the steam delivery process, a part of the steam is transmitted to the inside of the sleeve 911 through the first connecting pipe, so that the internal pressure of the sleeve 911 increases, the gas pushes the circular plate 912 to move downward, and at the same time drives the sliding rod 913 and the pressing block 914 to move downward, and the pressing block 914 will squeeze the driving valve 910 on the flushing tube 916 during the downward movement. The switch on the surface causes the driving valve 910 to automatically open for a period of time. At this time, the clean water in the clean water tank 917 enters the interior of the steering tube 906 through the flushing pipe 916 and squeezes the piston B907 to move. The piston B907 moves toward the direction of the limit plate 908 to prevent the clean water from entering the bottom of the water supply pipe 10. The clean water enters the filter cartridge 902 and flows to the top of the filter cartridge 902. Due to the closure of the one-way valve, the clean water is discharged from the drainage hole 904 set on the outer wall of the cleaning ring 903. The thrust generated when the water flow is discharged is used to make the cleaning ring 903 move slowly downward inside the filter cartridge 902. This movement of the cleaning ring 903 promotes the flow of clean water inside the filter cartridge 902, enhances the flushing effect of the water flow on the filter element, ensures that the impurities and pollutants accumulated on the surface of the filter element are effectively removed, improves the cleaning efficiency of the filter element, and reduces the workload of manual maintenance through the automated flushing process, thereby extending the service life of the filter element.

[0023] See also Figure 6 As shown, the sleeve 706 and the steam box 801 are fixedly connected via the gas pipe D809, a one-way air intake valve is fixedly installed at the bottom of the sleeve 706, and a solenoid valve is provided at the connection between the gas pipe D809 and the sleeve 706, which can quickly release pressure as needed.

[0024] See also Figures 1 to 3As shown, the disinfection mechanism 8 includes a steam box 801 fixedly installed on one side of the water dispenser body 1, a fixed plate 802 is fixedly installed on one side of the steam box 801, a conduction rod 803 is movably connected to the top of the fixed plate 802, a pressure relief valve 804 is fixedly installed on the top of the conduction rod 803, and the steam box 801 and the conduction rod 803 are fixedly connected via an air pipe C807.

When the pressure inside the sleeve 706 reaches a certain threshold, the solenoid valve inside the sleeve 706 opens, so that the gas in the sleeve 706 is transported to the steam box 801 through the gas pipe D809 for storage. When it is necessary to disinfect the cup in the placement box 3, the cup is taken out of the placement box 3 and placed above the disinfection plate 805 of the disinfection mechanism 8, and the cup is placed downward on the top of the pressure plate 806 so that the inner bottom end of the cup contacts the top of the pressure plate 806, and then the cup is pressed downward so that the inner bottom end of the cup drives the disinfection plate 805 to press the pressure relief valve 804 through the pressure plate 806. When the pressure relief valve 804 is under force, the steam inside the steam box 801 is discharged through the conduction rod 803, and the steam is ejected through the exhaust holes on the surface of the sterilization plate 805 to sterilize the inside of the cup. After sterilization, the cup is scrubbed with a brush 808 to further improve the sanitary quality. The sterilization mechanism 8 utilizes the high temperature and pressure of the steam to sterilize the cup, and at the same time combines the physical scrubbing of the brush 808 to achieve deep cleaning and disinfection of the cup, which not only improves the sterilization efficiency, but also reduces the use of chemical disinfectants by physical means, which is more environmentally friendly and safe.

[0026] See also Figure 8 As shown, the outer wall of the cleaning ring 903 is provided with multiple sets of drainage holes 904 , a spring C905 is provided between the cleaning ring 903 and the filter element cover 901 , and a one-way valve is installed inside the cleaning ring 903 .

The sleeve 911 is fixedly connected to the air pipe D809 through a first connecting pipe.

[0029] See also Figures 7 and 8 As shown, one end of the driving valve 910 is fixedly connected to the flushing pipe 916, and a clean water tank 917 is fixedly installed inside the water dispenser body 1. The flushing pipe 916 and the clean water tank 917 are fixedly connected via a second connecting pipe. The flushing pipe 916 facilitates the transportation of clean water required for cleaning, and the clean water tank 917 can provide clean water required for cleaning.

[0030] See also Figure 2 As shown, a box door is hinged on the front of the placement box 3, and a placement rack is fixedly installed inside the placement box 3.

[0031] Working principle: When in use, when the heating water tank 6 inside the water dispenser body 1 heats water, steam will be generated. When the steam pressure inside the heating water tank 6 reaches a certain threshold, the steam will push open the plug 703 inside the shell 701. After the plug 703 is pushed open, the air pump 4 starts and starts working. The gas generated by the air pump 4 is mixed with the steam generated by the heating water tank 6 and transmitted through the air pipe A705. The mixed gas enters the sleeve 706, which increases the air pressure inside the sleeve 706 and pushes the internal piston A707 downward. The movement of the piston A707 compresses the air under the sleeve 706, providing pressure for the ozone inside the ozone box 709, so that it is quantitatively transported through the air pipe B710. The ozone is transported to the water storage tank 5 through the air pipe B710 to disinfect and purify the pure water in the water storage tank 5, thereby improving the water purification efficiency. In addition, the safety of the water quality is enhanced through ozone disinfection. At the same time, when the pressure inside the sleeve 706 reaches a certain threshold, the solenoid valve inside the sleeve 706 opens, so that the gas in the sleeve 706 is transported to the steam box 801 for storage through the gas pipe D809. When the cup in the placement box 3 needs to be sterilized, the cup is taken out of the placement box 3, placed on the sterilization plate 805 of the sterilization mechanism 8, and the cup is placed downward on the top of the pressing plate 806 so that the inner bottom end of the cup contacts the top of the pressing plate 806, and then the cup is pressed downward so that the inner bottom end of the cup drives the sterilization plate 805 to press the pressure relief valve 804 through the pressing plate 806. When the pressure relief valve 804 is stressed, the steam inside the steam box 801 is discharged through the conduction rod 803, and the steam is ejected through the exhaust holes on the surface of the sterilizing plate 805 to sterilize the inside of the cup. After sterilization, the cup is scrubbed with a brush 808 to further improve the sanitary quality. The sterilizing mechanism 8 utilizes the high temperature and pressure of the steam to sterilize the cup, and at the same time combines the physical scrubbing of the brush 808 to achieve deep cleaning and sterilization of the cup, which not only improves the sterilization efficiency, but also reduces the use of chemical disinfectants by physical means, which is more environmentally friendly and safe. In addition, during the steam delivery process, a portion of the steam is transmitted to the interior of the sleeve 911 through the first connecting pipe, so that the internal pressure of the sleeve 911 increases, and the gas pushes the circular plate 912 to move downward, while driving the sliding rod 913 and the pressing block 914 to move downward. During the downward movement of the pressing block 914, the switch on the surface of the driving valve 910 on the flushing pipe 916 is squeezed, so that the driving valve 910 automatically opens for a period of time. At this time, the clean water in the clean water tank 917 enters the interior of the steering pipe 906 through the flushing pipe 916 and squeezes the piston B907 to move. The piston B907 moves toward the limit plate 908 to prevent the clean water from entering the water delivery pipe 10. At the bottom, clean water enters the filter cartridge 902 and flows to the top of the filter cartridge 902. Due to the closure of the one-way valve, the clean water is discharged from the drainage hole 904 set on the outer wall of the cleaning ring 903. The thrust generated when the water flows out is used to make the cleaning ring 903 move slowly downward inside the filter cartridge 902. This movement of the cleaning ring 903 promotes the flow of clean water inside the filter cartridge 902, enhances the flushing effect of the water flow on the filter element, ensures that the impurities and pollutants accumulated on the surface of the filter element are effectively removed, improves the cleaning efficiency of the filter element, and reduces the workload of manual maintenance through the automated flushing process, thereby extending the service life of the filter element.
