[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] A device for simulating and demonstrating the flow of water using an electromagnetic water meter includes: a water tank 1; an electromagnetic water meter body 2 is disposed inside the water tank 1, an output pipe 3 is disposed on one side of the electromagnetic water meter body 2, a connecting pipe 4 is disposed on the side of the electromagnetic water meter body 2 away from the output pipe 3, and a water pump 5 is disposed at the end of the connecting pipe 4 away from the electromagnetic water meter body 2; both sides of the electromagnetic water meter body 2 are provided with a disassembly and assembly mechanism 6 for quick replacement of the electromagnetic water meter body 2; a quick-replaceable filter mechanism 7 is disposed on the outer surface of the input end of the water pump 5. The user adds an appropriate amount of water to the water tank 1, then installs the electromagnetic water meter body 2 inside the water tank 1 through the disassembly and assembly mechanism 6, starts the water pump 5, and pumps the water from the water tank 1 to the electromagnetic water meter body 2, and then delivers it back into the water tank 1 through the output pipe 3, thereby enabling the electromagnetic water meter body 2 to detect and demonstrate the flow of water.

[0028] like Figure 3 and Figure 5As shown, the disassembly and assembly mechanism 6 includes: first connectors 8 fixedly connected to both sides of the electromagnetic water meter body 2; a matching second connector 9 provided on the side of the first connector 8 away from the electromagnetic water meter body 2; two buckles 10 fixedly connected to the outer surface of each first connector 8; each buckle 10 having a slot 11 inside; an L-shaped locking plate 12 fixedly connected to each second connector 9 near the slot 11; the L-shaped locking plate 12 is adapted to the buckles 10 and the slot 11; the two second connectors 9 are fixedly connected to the connecting pipe 4 and the output pipe 3 respectively; a first sealing ring 13 is embedded inside each first connector 8; a second sealing ring 14 is embedded inside each second connector 9; the first sealing ring 13 and the second sealing ring 14 are adapted to each other; the user can disassemble the electromagnetic water meter when necessary. When the main body 2 is in operation, the electromagnetic water meter main body 2 can be rotated clockwise. The electromagnetic water meter main body 2 drives the first connector 8, and the first connector 8 drives the buckle 10 to rotate. As the buckle 10 rotates, the slot 11 separates from the L-shaped locking plate 12 on the second connector 9. During installation, the user places the electromagnetic water meter main body 2 between the two second connectors 9, then brings the buckle 10 on the first connector 8 close to one end of the inclined surface of the L-shaped locking plate 12, and finally rotates the electromagnetic water meter main body 2 counterclockwise. The electromagnetic water meter main body 2 drives the buckle 10 to rotate. As the buckle 10 rotates, the slot 11 inside the buckle 10 is engaged with the outer surface of the L-shaped locking plate 12, and the first sealing ring 13 and the second sealing ring 14 can seal the connection to prevent water leakage.

[0029] like Figure 2 , Figure 4 and Figure 6As shown, the filtration mechanism 7 includes: a filter box 15 fixedly connected to the outer surface of the input end of the water pump 5; a crossbeam 16 fixedly connected to the bottom of the filter box 15; mounting plates 17 fixedly connected to both ends of the crossbeam 16; the mounting plates 17 are connected to the water tank 1 by bolts; an input pipe 18 fixedly connected to the side of the filter box 15 away from the water pump 5; a first vertical pipe 19 fixedly connected to one end of the input pipe 18 inside the filter box 15; a second vertical pipe 20 fixedly connected to one end of the output end of the water pump 5 inside the filter box 15; a filter frame 21 is provided between the first vertical pipe 19 and the second vertical pipe 20; a limiting plate 22 is fixedly connected to the top of the filter frame 21; a handle 23 is fixedly connected to the top of the limiting plate 22; filter screens 24 are fixedly connected to both sides inside the filter frame 21; and an activated carbon filter is provided between the two filter screens 24. The activated carbon layer 25 has a cotton yarn layer 26 on one side and a purification layer 27 on the side of the cotton yarn layer 26 away from the activated carbon layer 25. When the water pump 5 is running, the water inside the water tank 1 flows into one side of the filter box 15 through the inlet pipe 18 and the first vertical pipe 19. After being filtered and purified by the filter screen 24, activated carbon layer 25, cotton yarn layer 26 and purification layer 27 inside the filter frame 21, the water flows into the second vertical pipe 20. The water inside the second vertical pipe 20 flows through the electromagnetic water meter body 2 through the water pump 5. When the filter material has been used for a long time, the user can pull the handle 23. The handle 23 drives the limit plate 22, and the limit plate 22 drives the filter frame 21, thereby pulling the filter frame 21 out of the filter box 15. After replacement, the filter frame 21 can be inserted into the filter box 15.

[0030] like Figure 4 As shown, limit frames 28 are provided on both sides of the filter frame 21. The limit frames 28 are fixedly connected to the filter box 15. A damping pad 29 with a sealing effect is provided between the limit frame 28 and the filter frame 21. The damping pad 29 is fixedly connected to the limit frame 28, which can seal the contact between the filter frame 21 and the filter box 15 to avoid leakage and poor filtration effect.

[0031] like Figure 1 and Figure 2 As shown, support rings 30 are fixedly connected to the outer surfaces of both the output pipe 3 and the input pipe 18. A first support frame 31 is fixedly connected to the bottom of each support ring 30, and a second support frame 32 is fixedly connected to the bottom of the water pump 5. The bottoms of the first support frame 31 and the second support frame 32 are connected to the water tank 1 by bolts, which improves the stability of the internal device.

[0032] like Figure 1 and Figure 2 As shown, a water outlet 33 is provided on one side of the water tank 1, and a valve 34 is provided inside the water outlet 33 to facilitate the user to drain the water inside the water tank 1.

[0033] like Figure 1 As shown, each of the four corners of the bottom of the water tank 1 is equipped with a universal wheel 35 with a braking function. The universal wheel 35 is fixedly connected to the water tank 1, making it convenient for users to move and fix the device.

[0034] Working principle: The user adds an appropriate amount of water to the water tank 1 and then starts the water pump 5. While the water pump 5 is running, the water inside the water tank 1 flows into one side of the filter box 15 through the inlet pipe 18 and the first vertical pipe 19. After being filtered and purified by the filter screen 24, activated carbon layer 25, cotton yarn layer 26 and purification layer 27 inside the filter frame 21, the water flows into the second vertical pipe 20. The water inside the second vertical pipe 20 flows through the electromagnetic water meter body 2 through the water pump 5, and finally is delivered back into the water tank 1 through the outlet pipe 3. This allows the electromagnetic water meter body 2 to control the flow of water. The system allows for testing and demonstration. After prolonged use of the filter media, the user can pull handle 23, which in turn moves the limiting plate 22, which in turn moves the filter frame 21, thus removing the filter frame 21 from the filter box 15. After replacement, the filter frame 21 can be inserted back into the filter box 15. This system not only filters and adsorbs impurities in the water, preventing them from affecting the display results of the electromagnetic water meter, but also facilitates filter media replacement, avoiding the problem of gradually decreasing filtration efficiency with long-term use. Users can also easily disassemble the electromagnetic water meter. When the main body 2 is in operation, the electromagnetic water meter main body 2 can be rotated clockwise. The electromagnetic water meter main body 2 drives the first connector 8, and the first connector 8 drives the buckle 10 to rotate. As the buckle 10 rotates, the slot 11 separates from the L-shaped locking plate 12 on the second connector 9. During installation, the user places the electromagnetic water meter main body 2 between the two second connectors 9, then brings the buckle 10 on the first connector 8 close to one end of the inclined surface of the L-shaped locking plate 12, and finally rotates the electromagnetic water meter main body 2 counterclockwise. The electromagnetic water meter main body 2 drives the buckle 10 to rotate, and as the buckle 10 rotates, the internal... The slot 11 fits onto the outer surface of the L-shaped locking plate 12, and the first sealing ring 13 and the second sealing ring 14 can seal the connection to prevent water leakage. This simplifies the replacement process of the electromagnetic water meter, making it convenient for users to replace the electromagnetic water meter at any time, improving its practicality. It solves the problem that existing electromagnetic water meter small flow simulation display devices can provide supply simulation display according to usage needs, but the electromagnetic water meter replacement process is relatively complicated. Since multiple electromagnetic water meters need to be displayed during the simulation display, the electromagnetic water meters need to be replaced constantly, resulting in poor practicality.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
