DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-4 The utility model provides a technical solution: an anti-scaling water distributor, comprising an inlet pipe 1, an outlet pipe 2, and a filter cylinder 3. The filter cylinder 3 can be detachably installed between the adjacent ends of the inlet pipe 1 and the outlet pipe 2. Filter nets 4 are placed at both ends of the filter cylinder 3. The inner wall of the inlet pipe 1 close to the filter cylinder 3 and the inner wall of the outlet pipe 2 close to the filter cylinder 3 are respectively formed with baffles 5 by metal welding;

[0022] The water inlet pipe 1 and the water outlet pipe 2 are respectively welded by metal to form a first connecting plate 6 at one end close to the filter cylinder 3. The two ends of the filter cylinder 3 are convex structures. The two ends of the filter cylinder 3 are respectively installed on the inner wall of the water inlet pipe 1 and the water outlet pipe 2 by threads. The filter screens 4 at the two ends of the inner wall of the filter cylinder 3 are respectively in conflict with the side surfaces of the two sets of baffles 5.

[0023] A detachably installed filter cylinder 3 is provided between the water inlet pipe 1 and the water outlet pipe 2, so that the filter screens 4 at both ends of the filter cylinder 3 can be tightly connected to the inner walls of the water inlet pipe 1 and the water outlet pipe 2 respectively through the external sealing ring 7, so that the water entering the water distributor is filtered twice, thereby achieving the effect of preventing scale in the water distributor;

[0024] The filter cylinder 3 can be quickly disassembled and assembled with the inner wall of one end of the water inlet pipe 1 and the water outlet pipe 2 through the threaded groove 31 opened on the periphery of the convex structure at the end, and the two ends of the filter cylinder 3 can respectively position the two groups of filter screens 4 against the inner wall baffles 5 at one end of the water inlet pipe 1 and the water outlet pipe 2, and are sealed and assembled with fixing bolts 34 through the external connecting plate, sealing ring 7 and rubber pad 33. This makes the filter cylinder 3 detachable and assembled between the water inlet pipe 1 and the water outlet pipe 2, so as to clean the impurities in the water filtered by the two groups of filter screens 4. Compared with the existing anti-scaling water distributor, the convex structure inside the water inlet pipe 1 and the filter screen 4 inside the shell can be disassembled to clean the impurities in the water filtered inside.

[0025] Among them, one end of the water inlet pipe 1 is integrally formed with a water inlet joint 11 through mold die-casting, and one end of the water outlet pipe 2 is integrally formed with a water outlet joint 21 through mold die-casting. The water inlet joint 11 at one end of the water inlet pipe 1 and the water outlet joint 21 at one end of the water outlet pipe 2 are both convex structures. Water can be introduced into the water distributor through the water inlet joint 11, and filtered twice through the filter nets 4 at both ends of the filter cylinder 3 to filter out impurities in the water, thereby having an anti-scale effect on the inside of the water distributor.

[0026] Among them, thread grooves 31 are respectively opened on the periphery of the convex structures at both ends of the filter cylinder 3, and the filter cylinder 3 is threadedly connected with the water inlet pipe 1 and one end of the water outlet pipe 2 through the thread grooves 31 at both ends. The filter cylinder 3 can be quickly disassembled and assembled with the inner wall of one end of the water inlet pipe 1 and the water outlet pipe 2 through the thread grooves 31 opened on the periphery of the convex structures at the ends.

[0027] Among them, the outer edges of the convex structures at both ends of the filter cylinder 3 are respectively integrally formed with second connecting plates 32 by metal welding, and rubber pads 33 are bonded to the outside of the second connecting plates 32. The connection between the water inlet pipe 1 and one end of the filter cylinder 3 and the connection between the water outlet pipe 2 and one end of the filter cylinder 3 are respectively provided with sealing rings 7. When the convex structures at both ends of the filter cylinder 3 are respectively threadedly connected with the inner walls of one end of the water inlet pipe 1 and the water outlet pipe 2 through the threaded grooves 31, the connection between the filter cylinder 3 and the water inlet pipe 1 and the water outlet pipe 2 is sealed and connected through the sealing ring 7, and after further sealing and connecting through the rubber pad 33 at the connection between the first connecting plate 6 and the second connecting plate 32, the connecting plates are connected with fixing bolts 34, which enables the two ends of the filter cylinder 3 to be sealed and assembled with the two ends of the water inlet pipe 1 and the water outlet pipe 2, thereby ensuring the sealing of the water distributor assembly.

[0028] Among them, a fixing bolt 34 is installed through a thread on the outer periphery of the connection between the second connecting plate 32 and the first connecting plate 6, and the rubber pad 33 located on the same side is located on the outside of the sealing ring 7 and conflicts with the sealing ring 7. The connection between the filter cylinder 3 and the water inlet pipe 1 and the water outlet pipe 2 is sealed by the sealing ring 7, and is further sealed by the rubber pad 33 at the connection between the first connecting plate 6 and the second connecting plate 32.

[0029] Working principle: When cleaning the impurities filtered inside the two sets of filter screens 4 inside the anti-scale water distributor, first loosen and disassemble the fixing bolts 34 at the connection between the water inlet pipe 1 and the filter cylinder 3. At this time, the rubber pad 33 between the water inlet pipe 1 and the connecting plate of the filter cylinder 3 can be separated. Then, the sealing ring 7 on the outer side of the convex structure of the filter cylinder 3 can be removed, and the threaded groove 31 at the connection between the water inlet pipe 1 and the filter cylinder 3 can be rotated and disassembled. At this time, the filter screen 4 on one side of the baffle plate 5 on the inner wall of the water inlet pipe 1 can be taken out, and the water impurities filtered at the convex structure between the water inlet pipe 1 and the water inlet joint 11 can be poured out and cleaned;

[0030] Similarly, the fixing bolt 34 at the connection between the outlet pipe 2 and one end of the filter cylinder 3 can be disassembled, and the filter screen 4 on one side of the baffle plate 5 on the inner wall of the outlet pipe 2 can be taken out, and the impurities in the filtered water between the outlet pipe 2 and the filter cylinder 3 can be poured out and cleaned;

[0031] When assembling the anti-scaling water distributor, the convex structures at both ends of the filter cylinder 3 can be threadedly connected to one end of the inner wall of the water inlet pipe 1 and the water outlet pipe 2 through the outer threaded groove 31 respectively, and the filter cylinder 3 is sealed and connected with the water inlet pipe 1 and the water outlet pipe 2 at the connection through the sealing ring 7, and is further sealed and connected through the rubber pad 33 at the connection between the first connecting plate 6 and the second connecting plate 32, and then the connecting plates are connected with fixing bolts 34, so that the two ends of the filter cylinder 3 can be sealed and assembled with the two ends of the water inlet pipe 1 and the water outlet pipe 2, thereby ensuring the sealing of the water distributor assembly.

[0032] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
