Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device for direct drinking water equipment which is easy to clean. Background Art

[0002] Direct drinking water equipment is a device used to directly provide drinking water that meets health standards after filtering, purifying and disinfecting tap water or other water sources. It can remove impurities, odors, discoloration, bacteria, viruses and other harmful substances in the water, making the water clear, transparent, good-tasting, safe and hygienic. However, the existing filtering devices used in direct drinking water equipment need to be manually disassembled and cleaned after long-term use. The cleaning steps are cumbersome and inefficient.

[0003] In order to address the above problems, a Chinese patent with the existing announcement number CN219662978U proposes a filtering device for direct drinking water equipment. The device supplies liquid water from a liquid supply pipe, and the liquid water flows out of the liquid supply pipe to act on the filter net. The filter net rotates around the rotating rod as the axis and drives the bristles to rotate to clean the inner circumference of the ring net.

[0004] However, although the above-mentioned filtering device for direct drinking water equipment can act on the filter screen through liquid water flowing out from the liquid supply pipe, the filter screen rotates with the rotating rod as the axis and drives the bristles to rotate to clean the inner circumference of the ring network. However, the filtering device for direct drinking water equipment will drive the bristles to clean the ring network when liquid water enters the box body, which makes the bristles run continuously, increases the running load of the bristles, and causes the service life of the bristles to be shortened. Therefore, the utility model provides a filtering device for direct drinking water equipment that is easy to clean to meet the needs. Utility Model Content

[0035] like Figures 1 to 7 As shown, an embodiment of the utility model provides a filtering device for a direct drinking water equipment that is easy to clean, including a main body 1, a filtering mechanism 6 is provided on the main body 1, a filter cartridge 12 is provided in the filtering mechanism 6, a rotating shaft 14 is rotatably connected to the filter cartridge 12, a plurality of cleaning rods 16 that are in contact with the inner wall of the filter cartridge 12 are provided along the circumference direction of the rotating shaft 14, a filter net 15 is provided between the cleaning rods 16 and the rotating shaft 14, a first water inlet pipe 7 that is connected to the filter cartridge 12 is penetrated at the bottom of the filtering mechanism 6, a second water inlet pipe 8 that is connected to the filter cartridge 12 is provided at the side of the filtering mechanism 6, and a drain pipe 11 is penetrated on the filtering mechanism 6, the drain pipe 11 is connected to a sewage pipe 2 and a water outlet pipe 5, a second valve 4 and a first valve 3 are provided on the sewage pipe 2 and the water outlet pipe 5 respectively, and an adjusting mechanism 9 for controlling the opening and closing of the first valve 3 and the second valve 4 is provided on the filtering mechanism 6.

[0036] Specifically, the opening and closing of the two valves are adjusted in opposition by the adjusting mechanism 9, and the connection between the external pipeline and the two water inlet pipes is changed at the same time, thereby reducing the operating load of the brush 17, avoiding the large operation range of the brush and shortening its service life, and solving the problem that the existing direct drinking water equipment uses a filter device that drives the bristles to clean the ring network when liquid water enters the box, which causes the bristles to continue to operate, increases the operating load of the bristles, and shortens the service life of the bristles.

[0037] It should be noted that the first water inlet pipe 7 is arranged parallel to the filter screen 15, and the second water inlet pipe 8 is arranged vertically to the filter screen 15. At the same time, a certain gap is reserved between the filter screen 15 and the top of the filter cartridge 12 to avoid that the water flow discharged into the filter cartridge 12 along the first water inlet pipe 7 can be alleviated, thereby minimizing the rotation amplitude of the filter screen 15 and the rotating shaft 14 when the filter cartridge 12 does not need to be cleaned; further, the first water inlet pipe 7 and the second water inlet pipe 8 can be connected to an external high-pressure water pipe, and the connection method thereof is the prior art. This embodiment aims to improve a filtering device for direct drinking water equipment proposed in the Chinese patent with announcement number CN219662978U. Compared with the former, this embodiment can minimize the loss of bristles.

[0038] like Figure 4 and Figure 5As shown, in this embodiment, the bottom of the filter cartridge 12 is a hollow structure with an opening at the bottom, and the bottom of the filter cartridge 12 is fixedly connected to the bottom of the filter mechanism 6. A plurality of filter holes are penetrated through the filter cartridge 12, and a plurality of filter holes are also penetrated through the filter screen 15. The diameter of the filter holes on the filter screen 15 is smaller than the diameter of the filter holes on the filter cartridge 12.

[0039] like Figures 4 to 6 As shown, in the present embodiment, the rotating shaft 14 extends to the top of the filter cartridge 12 and is rotatably connected to the top of the filter mechanism 6, and a plurality of cleaning rods 13 are fixedly connected along the circumference direction of the rotating shaft 14, and a plurality of bristles that fit the outer wall of the filter cartridge 12 are fixedly connected along the length direction of the cleaning rod 13 and the cleaning rod 2 16, and the cleaning rod 13 and the cleaning rod 2 16 are both L-shaped structures. Specifically, the length of the cleaning rod 13 is less than the length of the cleaning rod 2 16, and the cleaning rod 13 and the cleaning rod 2 16 are relatively arranged on the outer wall and the inner wall of the filter cartridge 12, and the bottom end of the cleaning rod 13 will not collide with the second water inlet pipe 8. The arrangement of the cleaning rod 13 and the cleaning rod 2 16 can achieve simultaneous cleaning of the inner wall and the outer wall of the filter cartridge 12, thereby improving the cleaning effect of the filter cartridge 12.

[0040] like Figures 3 to 5 As shown, in the present embodiment, the end of the second water inlet pipe 8 facing away from the filter cartridge 12 is connected with a connecting pipe 10, and the connecting pipe 10 is a funnel-shaped structure with a cross-sectional area gradually increasing from one end connected to the second water inlet pipe 8 to the other end. Specifically, the setting of the connecting pipe 10 is conducive to increasing the pressure of water discharged to the second water inlet pipe 8, thereby increasing the amplitude of the movement of the filter screen 15 and increasing the cleaning effect on the filter cartridge 12.

[0041] like Figure 7 As shown, in this embodiment, the regulating mechanism 9 includes a bevel gear 1 91, which is sleeved on the regulating shaft of the first valve 3, a bevel gear 2 92, which is sleeved on the regulating shaft of the second valve 4, the bevel gear 2 92 is meshed with the bevel gear 1 91, and a threaded rod 93, which is threadedly connected to the filter mechanism 6, one end of the threaded rod 93 is fixedly connected to the regulating shaft of the first valve 3, and the other end extends to the outside of the body 1. Specifically, the first valve 3 and the second valve 4 can be ball valves, butterfly valves, etc. in the prior art. The regulating mechanism 9 can adjust the opening and closing of the first valve 3 and the second valve 4, that is, when the first valve 3 is opened, the second valve 4 is closed, and vice versa. At the same time, the installation method of the first valve 3, the second valve 4 and the regulating mechanism 9 is the prior art.

[0042] like Figure 1 As shown, in this embodiment, a placement box 18 is provided on the main body 1 , and the inlet ends of the first water inlet pipe 7 and the second water inlet pipe 8 are both located in the placement box 18 .

[0043] Working principle:

[0044] When the filter cartridge 12 needs to be cleaned, the water pipe of the external high-pressure water source is connected to the second water inlet pipe 8, and the threaded rod 93 is rotated at the same time, so that the threaded rod 93 drives the bevel gear 1 91 and the bevel gear 2 92 to rotate, and the bevel gear 1 91 drives the first valve 3 to close, and the bevel gear 2 92 drives the second valve 4 to open, so that the drain pipe 11 and the sewage outlet are connected. At this time, the water flows into the filter cartridge 12 through the second water inlet pipe 8, and pushes the filter screen 15 to drive the rotating shaft 14 to rotate, so that the cleaning rod 13 and the cleaning rod 2 16 drive the bristles to clean the outer wall and the inner wall of the filter cartridge 12, and the cleaned water flows to the drain pipe 11, and then is discharged along the sewage outlet. Similarly, when it is not necessary to clean the filter cartridge 12, the first valve 3 is opened by adjusting the adjustment mechanism 9, and the second valve 4 is closed at the same time. Then, the water pipe of the external high-pressure water source is connected to the first water inlet pipe 7. Since the first water inlet pipe 7 is arranged in parallel with the filter screen 15, the water flow will not greatly push the filter screen 15 and the rotating shaft 14 to rotate, thereby avoiding the large range of movement of the brush and causing its service life to be shortened, reducing the operating load of the brush 17, and solving the problem that the existing direct drinking water equipment filtering device will drive the bristles to clean the ring network when liquid water enters the box, which makes the bristles continue to operate, increases the operating load of the bristles, and shortens the service life of the bristles.
