Implementation Method

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] like Figure 1-8 As shown, as an embodiment of the present invention, a filtering device for direct drinking water equipment, the filtering device for direct drinking water equipment includes:

[0036] A water dispenser 1 is provided with a filter structure 2 inside the water dispenser 1, and the filter structure 2 is used to filter impurities in the direct drinking water;

[0037] A sealing installation structure 3 is installed inside the filter structure 2 to achieve a sealed installation between the components of the filter structure 2 and a fixed installation between the filter structure 2 and the water dispenser 1;

[0038] Compared with the existing technology and the traditional integrated filtering design, the filtering structure 2 can facilitate the cleaning of the filter 26 by separating the filter 26 from other components, so that people can clean the filter by conventional means. By setting the sealing installation structure 3, the separate filtering structure 2 can be sealed and installed, and the filtering structure 2 after forming the "integrated" structure can also be fixedly installed with the water dispenser 1.

[0039] like Figure 1-4 As shown, as a preferred embodiment of the present invention, the filtering structure 2 includes:

[0040] The mounting plate 21 is L-shaped and has a longer end that is horizontally arranged. A mounting groove 11 is provided in the middle of the water dispenser 1. The mounting plate 21 slides along the path of the mounting groove 11. The interior of the mounting plate 21 is rotatably connected to a mounting frame 24. The middle of the mounting frame 24 is rotatably connected to a filter screen 26.

[0041] A connecting pipe 23 is fixedly installed inside the water dispenser 1, and a filter 26 is located between two segmented connecting pipes 23;

[0042] A guide plate 13 is fixedly installed on the inner side of the mounting groove 11, and a guide groove 28 is provided on the outer side of the mounting plate 21. The guide groove 28 and the guide plate 13 are slidably fitted together to provide a guide for the mounting plate 21 during the sliding process along the mounting groove 11, and at the same time, it can also avoid the imbalance of the center of gravity caused by the excessive weight of the upper half of the mounting plate 21.

[0043] A placement slot 12 is provided on one side of the water dispenser 1 , and a water outlet 22 is provided at the top of the placement slot 12 . The water outlet 22 is connected to a connecting pipe 23 . When water needs to be collected, the water cup is placed in the placement slot 12 directly below the water outlet 22 .

[0044] In addition to the above technical solution, the present invention also provides another embodiment, which differs from the above embodiment in that the filter screen 26 in the filter structure 2 is replaced with a filter element, which can also filter drinking water.

[0045] like Figure 2-8 As shown, as a preferred embodiment of the present invention, the sealing installation structure 3 includes:

[0046] A threaded rod 31 rotatably connected to the intersection of the vertical end and the horizontal end of the mounting plate 21 , wherein one end of the threaded rod 31 located inside the mounting plate 21 is fixedly connected to a worm gear 33 ;

[0047] A fixing block 32 is provided with a rectangular groove 27 in the middle of the vertical end of the mounting plate 21. The fixing block 32 slides along the path of the rectangular groove 27. A threaded groove 313 and a retaining groove 314 are provided at both ends of the fixing block 32. The threaded rod 31 is threadedly engaged with the threaded groove 313. A retaining block 315 is fixedly installed on one side of the rectangular groove 27 inside the mounting groove 11. The retaining groove 314 and the retaining block 315 are slidably engaged with each other.

[0048] An adjusting shaft 36 is rotatably connected to the interior of the mounting plate 21. One end of the adjusting shaft 36 is fixedly connected to a worm 37 and a transmission wheel 38. The worm 37 is in transmission connection with the worm wheel 33.

[0049] A transmission shaft 310 is rotatably connected to the interior of the mounting plate 21. One end of the transmission shaft 310 is fixedly connected to a second transmission wheel 311 and a transmission gear 312. The second transmission wheel 311 is connected to the first transmission wheel 38 via a transmission member 39.

[0050] The ring gear 35 is fixedly mounted on the arc-shaped outer wall of the mounting frame 24 and meshes with the transmission gear 312 for transmission;

[0051] A sealing ring 34 is slidably connected to the interior of the mounting plate 21 and threadedly engaged with the mounting frame 24. An annular groove 25 is provided in the middle of the connecting tube 23, and the sealing ring 34 is slidably engaged with the annular groove 25;

[0052] In order to avoid the difficulty of cleaning the filter device inside the water dispenser 1 due to the integrated structure, the filter structure 2 is set to a detachable structure. The mounting plate 21 is pushed inward along the mounting groove 11 in the middle of the water dispenser 1 until it is completely fitted with the inner wall of the mounting groove 11. By controlling the rotation of the adjustment shaft 36 inside the mounting plate 21, the adjustment shaft 36 drives the transmission wheel 1 38 to rotate. Since the transmission wheel 1 38 is connected to the transmission wheel 2 311 through the transmission member 39, it can further drive the transmission shaft 310 to rotate, and the transmission shaft 310 further drives the transmission wheel 310 to rotate. The dynamic transmission gear 312 rotates, and due to the meshing transmission between the transmission gear 312 and the ring gear 35, it can further drive the mounting frame 24 to rotate around the inside of the mounting plate 21. Due to the threaded fit between the mounting frame 24 and the sealing ring 34, the rotation of the mounting frame 24 can make the sealing rings 34 at both ends of the mounting frame 24 move in the vertical direction (and the movement directions are different), so that the raised portion of the sealing ring 34 forms a sliding fit with the annular groove 25 in the middle of the connecting pipe 23, and finally realize the sealed connection between the two-segment connecting pipe 23 and the filter screen 26.

[0053] The filter screen 26 is made of Hastelloy material, which can improve the corrosion resistance of the filter screen.

[0054] The outer side of the mounting plate 21 is hingedly provided with a pull ring 29 , and by pulling the pull ring 29 , the mounting plate 21 can slide along the mounting groove 11 more conveniently and labor-savingly.

[0055] As the adjusting shaft 36 drives the transmission wheel 38 to rotate, the worm 37 also rotates accordingly. Due to the transmission connection between the worm 37 and the worm wheel 33, the threaded rod 31 can be further driven to rotate. Due to the threaded fit between the threaded rod 31 and the fixing block 32, the rotation of the threaded rod 31 can cause the fixing block 32 to slide vertically along the path of the rectangular groove 27, and finally form a sliding fit between the locking groove 314 and the locking block 315 below the installation groove 11, completing the fixed installation between the mounting plate 21 and the water dispenser 1. When the water dispenser 1 has accumulated a lot of dirt on the filter 26 due to long-term use of the water dispenser 1, the sealing ring 34 can be disengaged from the connecting pipe 23 by controlling the adjusting shaft 36 inside the mounting plate 21 to rotate in the opposite direction. At the same time, the locking block 315 is also disengaged from the locking groove 314. By pulling the pull ring 29, the entire mounting plate 21 can be removed from the mounting groove 11, and the filter 26 can be cleaned. After the filter 26 is cleaned, it can be installed again.

[0056] In addition to the above technical solution, the present invention also provides another embodiment, which differs from the above embodiment in that the transmission connection between the worm 37 and the worm wheel 22 is replaced by a bevel gear transmission, which can also realize the transmission connection between the adjusting shaft 36 and the threaded rod 31.

[0057] The working principle of the present invention is:

[0058] In this embodiment, in order to avoid the difficulty of cleaning the filter device inside the water dispenser 1 due to its integrated structure, the filter structure 2 is set to a detachable structure. The mounting plate 21 is pushed inward along the mounting groove 11 in the middle of the water dispenser 1 until it is completely in contact with the inner wall of the mounting groove 11. By controlling the rotation of the adjustment shaft 36 inside the mounting plate 21, the adjustment shaft 36 drives the transmission wheel 1 38 to rotate. Since the transmission wheel 1 38 is connected to the transmission wheel 2 311 through the transmission member 39, the transmission shaft 310 can be further driven to rotate. The transmission shaft 310 further drives the transmission gear 312 to rotate. Due to the meshing transmission between the transmission gear 312 and the ring gear 35, the mounting frame 24 can be further driven to rotate around the inside of the mounting plate 21. Due to the threaded fit between the mounting frame 24 and the sealing ring 34, the rotation of the mounting frame 24 can cause the sealing rings 34 at both ends of the mounting frame 24 to move in the vertical direction (and the moving directions are different), so that the protrusion of the sealing ring 34 forms a sliding fit with the annular groove 25 in the middle of the connecting pipe 23. Finally, a sealed connection between the two-segment connecting pipe 23 and the filter screen 26 is achieved, and as the adjusting shaft 36 drives the transmission wheel 38 to rotate, the worm 37 also rotates accordingly. Due to the transmission connection between the worm 37 and the worm wheel 33, the threaded rod 31 can be further driven to rotate. Due to the threaded fit between the threaded rod 31 and the fixed block 32, the rotation of the threaded rod 31 can make the fixed block 32 slide vertically along the path of the rectangular groove 27, and finally form a sliding fit between the positioning groove 314 and the positioning block 315 below the installation groove 11, completing the process of the invention. The mounting plate 21 is fixedly installed with the water dispenser 1. When a lot of dirt accumulates on the filter screen 26 due to long-term use of the water dispenser 1, the sealing ring 34 and the connecting pipe 23 can be disengaged by controlling the adjustment shaft 36 inside the mounting plate 21 to rotate in the opposite direction. At the same time, the positioning block 315 and the positioning groove 314 are also disengaged. The entire mounting plate 21 can be removed from the mounting groove 11 by pulling the pull ring 29, and the filter screen 26 can be cleaned. After the filter screen 26 is cleaned, it can be installed again.
