[0025] By adopting the above technical solutions, the following beneficial effects can be formed by the present invention:

[0026] (1) In the present invention, a side connection pipe is connected to one side of the main water pipe through a water inlet three-way and a water outlet three-way. A bullet-shaped inner bullet core that bounces upward is installed in the main pipe of the water inlet three-way. And water passing holes are opened at the top end of the inner bullet core.

The water-driven impeller can drive the rotation of the filter cartridge located inside the filter box through a quick-insert component; after the water pressure drops, the purpose of connecting the water circuit in the side connection pipe to drive the filter cartridge is that the blockage of the filter holes will lead to a decrease in the filtering ability and a drop in the water pressure. By rotating the filter cartridge, on the one hand, the contact position between the filter cartridge and the main pipe of the main water pipe can be replaced, so that the filter holes at different positions enter the filtering working state. On the other hand, the outer cylinder wall of the filter cartridge can be in contact with the scraping steel brush installed inside the main water pipe to achieve the purpose of cleaning the filter holes; thus, after the filter holes on the cylinder wall of the filter cartridge are blocked and the water pressure in the main water pipe drops, the water circuit can be connected to the side connection pipe to realize the rotation of the filter cartridge and the automatic cleaning of the filter holes.

Detailed Embodiment

[0039] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] The following refers to the attached Figures 1-9 An example description is given of a water supply and drainage pipe connection structure with filtering and self-cleaning functions provided by the present invention.

[0041] Embodiment 1:

[0042] In the case of normal use of the filter holes 307, examples of the normal water supply of the main water pipe 102 are as Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 and Figure 9 shown;

[0043] The main water pipe 102 in the main pipe member 1 is connected to the outlet end on the lower side of the inlet tee 101, and the inlet end of the outlet tee 103 is connected to the outlet end of the main water pipe 102;

[0044] The outlet end on the side of the inlet tee 101 is connected to the side connection pipe member 2, and the outlet end of the side connection pipe member 2 is unidirectionally connected to the outlet end of the main pipe member 1;

[0045] A filter box 301 is connected to the main pipe of the main component 1. A filter cartridge 306 is rotatably connected inside the filter box 301. A plug-in hexagonal groove 308 is opened at the outer end of the rotating shaft of the filter cartridge 306.

[0046] An inner retaining ring 601 is fixedly connected inside the water inlet end of the water inlet tee 101. Slide columns 603 are symmetrically fixed to the outer top end of the inner elastic core 602. The inner elastic core 602 is slidably connected to the inner retaining ring 601 through the slide columns 603, so that the inner elastic core 602 can only move radially and will not rotate axially. A water passing hole 604 is opened at the top end of the main body of the inner elastic core 602. An inner fixing ring 605 is fixedly connected inside the inner elastic core 602. The water inlet end of the main water pipe 102 is fixedly connected with an inner support ring 607. One end of a compression spring 606 is clamped on one side of the inner support ring 607, and the other end is clamped on one side of the inner fixing ring 605.

[0047] Moreover, through holes are opened in the middle parts of the main bodies of the inner retaining ring 601, the inner fixing ring 605 and the inner support ring 607, which can realize the circulation of water. And the through hole in the main body of the inner retaining ring 601 does not intersect with the array of water passing holes 604. After the outer top surface of the inner elastic core 602 fits with the bottom surface of the inner retaining ring 601, it can play a role in cutting off the water circulation.

[0048] Inside the side water outlet end of the water inlet tee 101, there is a side core 701 connected to the main pipe of the water inlet tee 101. A side core hole 702 is opened in the side core 701. A lateral water passing hole 703 is opened on the side wall of the inner elastic core 602. And when the water pressure in the main component 1 is normal, the lateral water passing hole 703 is in a position where it does not communicate with the side core hole 702 downward. After the water pressure in the main component 1 drops, the lateral water passing hole 703 moves upward to communicate with the side core hole 702, which can make the water enter the side connecting pipe 201.

[0049] The water inlet end of the water inlet tee 101 and the water outlet end of the water outlet tee 103 are communicated with external pipelines.

[0050] Since the water pressure at this time is normal, the water pressure of the water passing through the water inlet tee 101 is sufficient to overcome the elastic force of the compression spring 606, so that the bottom end of the inner elastic core 602 abuts against the top end of the inner support ring 607.

[0051] At this time, there is enough gap between the top end of the inner elastic core 602 and the inner retaining ring 601. The water in the water inlet tee 101 will enter the inner elastic core 602 from the water passing hole 604, and then enter the main water pipe 102 through the through hole of the inner support ring 607. After being filtered by the filter cartridge 306 in the filter box 301, the filter holes 307 opened on the wall of the filter cartridge 306 can intercept and filter the impurities in the water, thereby improving the water supply quality of the water.

[0052] And at this time, the lateral water passing hole 703 is in a position where it faces downward and is not opposite to the side core hole 702, and the water in the water inlet tee 101 cannot enter the side connecting pipe 201.

[0053] Embodiment 2:

[0054] On the basis of Embodiment 1, examples of the automatic cleaning work of the filter holes 307 in the present invention are as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 shown;

[0055] The water inlet end of the side connecting pipe 201 in the side connecting pipe member 2 is connected to the water outlet end on the side of the water inlet tee 101, the water outlet end of the side connecting pipe 201 is connected to the water inlet end on the side of the water outlet tee 103, and a one-way valve 202 is installed in the pipeline of the side connecting pipe 201 close to the water outlet tee 103, which only allows the water in the side connecting pipe 201 to flow in the direction from the water inlet tee 101 to the water outlet tee 103;

[0056] The filter box 301 in the cylindrical filter assembly 3 is connected in the pipeline of the main water passing pipe 102, the end cover 302 is capped at the opening on one side of the filter box 301, the filter cylinder 306 is screwed in the cavity formed by the filter box 301 and the end cover 302, the outer end center of the filter cylinder 306 is fixed with a filter cylinder shaft 305, and a plug-in hexagonal groove 308 is opened at the outer end of the filter cylinder shaft 305; a end seat 303 is fixedly installed in the middle of the main body of the end cover 302, a filter cylinder sealing ring 304 is installed and fixed in the end seat 303, and the filter cylinder shaft 305 is rotatably connected in the filter cylinder sealing ring 304; filter holes 307 are opened in the cylinder wall of the filter cylinder 306;

[0057] A detachable inner retaining cover 309 is installed in the inner hole at the inner end of the filter cylinder 306. After the inner retaining cover 309 is removed, the whole filter cylinder 306 can be cleaned;

[0058] And a scraping steel brush 310 is also fixed inside the main water passing pipe 102. The scraping steel brush 310 contacts the outer cylinder wall of the filter cylinder 306 and does not affect the flow of water in the main water passing pipe 102. After the filter cylinder 306 rotates, the blocked filter holes 307 can be cleaned;

[0059] The water moving cavity 401 in the water moving member 4 is connected in the pipeline of the side connecting pipe 201, the cavity cover 402 is capped at the opening on one side of the water moving cavity 401, and an inner rotating seat 403 is fixedly installed in the middle of the bottom end of the inner cavity of the water moving cavity 401. The inner end of the rotating shaft of the water moving impeller 404 is rotatably connected in the inner rotating seat 403;

[0060] In the middle of the main body of the cavity cover 402, a cavity seat 405 is fixedly installed. A water dynamic sealing ring 406 is installed and fixed in the cavity seat 405. The outer end of the rotating shaft of the water dynamic impeller 404 is rotatably connected in the water dynamic sealing ring 406. A rotating hexagonal groove 407 is opened at the outer end of the rotating shaft of the water dynamic impeller 404.

[0061] In the middle of the main body of the connecting column 501 in the quick-insert component 5, an internal hexagonal sliding groove 502 is horizontally opened. A middle-position plate 503 is fixedly connected to the inner middle part of the internal hexagonal sliding groove 502. The inner end of each group of hexagonal insertion columns 505 is sleeved and fixed with a hexagonal sliding column 506. The hexagonal sliding column 506 is slidably connected in the internal hexagonal sliding groove 502. An outer limit seat 504 is fixedly connected to the outer end face of the connecting column 501. The hexagonal insertion column 505 is slidably connected in the outer limit seat 504. The outer limit seat 504 can prevent the hexagonal insertion column 505 from slipping off the connecting column 501.

[0062] In the middle of the main body of the hexagonal insertion column 505, an inner groove 507 is also horizontally opened, and the inner groove 507 is in a non-through state. An inner top spring 508 is clamped between the inner bottom surface of the inner groove 507 and the side surface of the middle-position plate 503, which can make the hexagonal insertion column 505 in a state of popping outwards.

[0063] The hexagonal insertion columns 505 at both ends of the connecting column 501 can be elastically inserted into the insertion hexagonal groove 308 and the rotating hexagonal groove 407 respectively. Through the quick-insert component 5, the quick connection between the water dynamic impeller 404 and the filter cartridge 306 can be realized.

[0064] After the filter holes 307 at the current position of the filter cartridge 306 wall are used for a period of time, the filter holes 307 will be blocked by impurities. The blockage of the filter holes 307 will cause the pressure of the water body in the main water pipe 102 to drop.

[0065] After the pressure of the water body in the main water pipe 102 drops, under the action of the elastic force of the compression spring 606, the inner elastic core 602 will elastically rise, so that the lateral water passing hole 703 can be connected to the side core hole 702.

[0066] After the lateral water passing hole 703 is connected to the side core hole 702, the water body in the water inlet tee 101 will enter the side connecting pipe 201 and flow to the water outlet tee 103 through the one-way valve 202. On the one hand, it realizes the water supply function of the side connecting pipe 201. On the other hand, it can drive the rotation of the water dynamic impeller 404 in the water dynamic cavity 401. The water dynamic impeller 404 drives the rotation of the filter cartridge 306 through the quick-insert component 5, so as to drive the rotation of the filter cartridge 306.

[0067] After the filter cartridge 306 rotates, on the one hand, the unused filter holes 307 can be replaced to the used state. On the other hand, the wall of the filter cartridge 306 can be in contact with the scraping steel brush 310, and the scraping steel brush 310 is used to clean the blocked filter holes 307. The cleaned impurities will be discharged along with the water body in the main water pipe 102.

[0068] Moreover, a sewage bypass is also connected to the water outlet end of the water outlet tee 103. When the water supply valve in the water supply pipeline of the water outlet tee 103 is closed, the water body containing impurities can be discharged outward through the sewage bypass, without affecting the water quality of the water supply in the water outlet tee 103;

[0069] Therefore, after the filter holes 307 are blocked and the water pressure in the main water pipe 102 drops, the work of automatically cleaning the filter holes 307 can be formed.

[0070] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
