[0044] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0045] Embodiment 1:

[0046] like Figure 1 As shown, this embodiment provides a large-caliber intelligent water supply meter, including: a water supply meter body 100, a water inlet pipe body 200 and a water supply filter assembly.

[0047] The water inlet pipe body 200 is connected to the water supply meter body 100 .

[0048] The water supply filter assembly is connected to the water inlet pipe body 200. The water supply meter body 100 is also connected to the water outlet pipe body, and the water supply filter assembly can also be selectively arranged on the water outlet pipe body. In addition, in order to be able to better arrange the water supply filter assembly, the caliber of the water inlet pipe body 200 needs to be set larger. Or it can be understood that: in order to be able to more easily and efficiently generate and manufacture the water supply filter assembly, the size of the water supply filter assembly needs to meet certain requirements (in short, it cannot be too small), and then in order to make the water inlet pipe body 200 match the size of the water supply filter assembly, the caliber of the water inlet pipe body 200 also needs to be set a little larger (in short, it cannot be too small).

[0049] like Figures 2 to 4 As shown, the water supply filter assembly includes: a filter housing 300 , a filter element 400 and a filter housing cover 500 .

[0050] like Figure 2 As shown, the filter housing 300 is provided with a housing cavity connected to the water inlet pipe body 200, and the top of the filter housing 300 is provided with a filter element inlet and outlet connected to the housing cavity. Specifically, the filter housing 300 can be arranged in a "U" shape. Figure 5 As shown, the first side wall (i.e., the first U-shaped side wall) of the filter housing 300 is provided with a water inlet hole 310, and the second side wall (i.e., the second U-shaped side wall) of the filter housing 300 is provided with a water outlet hole 320. The water inlet pipe body 200 includes a first pipe body connected to the first side wall of the filter housing 300 and docked with the water inlet hole 310, and a second pipe body connected to the second side wall of the filter housing 300 and docked with the water outlet hole 320. The first side wall and the second side wall of the filter housing 300 are arranged opposite to each other, and the filter housing 300 is integrally connected to the first pipe body and the second pipe body. The other end of the first pipe body is used to be connected to a tap water pipe, and the other end of the second pipe body is integrally connected to the water supply meter body 100.

[0051] The filter element 400 is disposed in the shell cavity, and the filter element 400 can be moved out of the shell cavity or moved into the shell cavity through the filter element inlet and outlet. When the filter element 400 is installed in the shell cavity, the filter element 400 just faces the water inlet hole 310 and the water outlet hole 320, and the tap water flowing through the filter housing 300 can be filtered through the filter element 400.

[0052] like Figure 1 As shown, the filter housing cover 500 is detachably connected to the filter element inlet and outlet of the filter housing 300 .

[0053] The water supply meter of this embodiment is provided with a water supply filter assembly on the water inlet pipe body 200, through which the tap water that needs to flow through the water supply meter body 100 can be filtered first, so as to prevent the tap water containing impurities and rust residues from affecting the water supply meter body 100, thereby enabling the water supply meter to be used for a long time and to always maintain the measurement accuracy.

[0054] After the water supply filter assembly has been used for a period of time, the filter element 400 can be replaced. The specific process of the replacement operation is as follows: first remove the filter shell cover 500 from the filter housing 300, then remove the old filter element 400 from the housing cavity through the filter element inlet and outlet, then install the new filter element 400 into the housing cavity through the filter element inlet and outlet, and finally connect and fix the filter shell cover 500 to the filter housing 300. The entire replacement operation of the filter element 400 is very simple.

[0055] Furthermore, the filter element 400 of this embodiment includes a filter frame 410 and a filter body 420 .

[0056] The filter frame 410 includes two vertical frames, a top frame connecting the top ends of the two vertical frames, and a bottom frame connecting the bottom ends of the two vertical frames. The vertical frames, the top frame, and the bottom frame form a frame opening arranged in the horizontal direction. In order to better assemble and connect with the filter housing 300, the shape of the frame opening can also be arranged in a "U" shape.

[0057] The filter body 420 is connected to the filter frame 410, and the filter body 420 is arranged in the frame opening. The filter body 420 can be a single layer or two or more layers of filter membrane. When the filter element 400 is installed into the housing of the filter housing 300, the frame opening just faces the water inlet 310 and the water outlet 320, so that the filter body 420 can effectively and comprehensively filter the tap water flowing through the filter housing 300.

[0058] like Figure 2 and Figure 5 As shown, a vertical limiting strip 330 and a bottom limiting strip 340 are provided in the shell cavity of the filter shell 300 .

[0059] like Figure 2 As shown, the vertical limiting strip 330 is connected to the vertical side wall of the housing cavity. A vertical limiting space is provided between the two vertical limiting strips 330 to allow the vertical frame of the filter frame 410 to be inserted.

[0060] The left vertical side wall of the shell cavity facing the left vertical frame is provided with two left vertical limiting strips 330, and a left vertical limiting space for allowing the left vertical frame to be inserted is provided between the two left vertical limiting strips 330, and the width of the left vertical limiting space is slightly greater than the width of the left vertical frame. The right vertical side wall of the shell cavity facing the right vertical frame is provided with two right vertical limiting strips 330, and a right vertical limiting space for allowing the right vertical frame to be inserted is provided between the two right vertical limiting strips 330, and the width of the right vertical limiting space is slightly greater than the width of the right vertical frame.

[0061] When the two vertical frames of the filter frame 410 are inserted into the two vertical limiting spaces, the vertical limiting strips 330 can vertically support the filter element 400 so that the filter body 420 of the filter element 400 can always face the water inlet hole 310 and the water outlet hole 320 .

[0062] like Figure 5 As shown, the bottom limiting strip 340 is connected to the bottom plate of the housing cavity. A bottom limiting space is provided between the two bottom limiting strips 340 to allow the bottom frame of the filter frame 410 to be inserted.

[0063] The arc-shaped bottom plate of the shell cavity facing the bottom frame is provided with two arc-shaped bottom limiting strips 340 , and a bottom limiting space allowing the bottom frame to be inserted is provided between the two bottom limiting strips 340 , and the width of the bottom limiting space is slightly larger than the width of the bottom frame.

[0064] The bottom limiting strip 340 can assist the vertical limiting strip 330 to better support the filter frame 410 vertically, thereby improving the installation stability of the filter frame 410 .

[0065] Further, such as Figure 4 As shown, the filter element 400 further includes a supporting baffle 430 .

[0066] The support baffle 430 is connected to the top frame of the filter frame 410. When the vertical frame of the filter frame 410 is inserted into the vertical limiting space until the support baffle 430 contacts the top surface of the vertical limiting strip 330, the bottom frame of the filter frame 410 is just inserted into the bottom limiting space. The shape and size of the support baffle 430 are the same as the shape and size of the filter element inlet and outlet. The support baffle 430 is located at the inner upper part of the shell cavity to prevent water from flowing upward out of the filter element inlet and outlet.

[0067] Further, such as Figure 3 As shown, the filter housing cover 500 includes: a cover plate 510 , a sealing gasket body 520 and a finger grip 530 .

[0068] The cover plate 510 is connected to the top of the filter housing 300. Specifically, a connection plate 350 is provided on the top of the filter housing 300, and a connection hole is provided on the connection plate 350; the cover plate 510 is provided with a docking hole connected to the connection hole through a connector. When the cover plate 510 is placed on the top of the filter housing 300, the cover plate 510 can be supported by the connection plate 350, and at this time, the docking hole of the cover plate 510 is exactly aligned with the connection hole of the connection plate 350, and the docking hole can be connected and fixed to the connection hole through a connector (such as a bolt and a nut), so that the cover plate 510 is connected and fixed to the connection plate 350 (i.e., the filter housing 300).

[0069] like Figure 3As shown, the sealing gasket body 520 is connected to the bottom of the cover plate 510, and the sealing gasket body 520 is plugged into the inlet and outlet of the filter element. The shape and size of the sealing gasket body 520 are also the same as the shape and size of the inlet and outlet of the filter element. When the cover plate 510 is connected and fixed to the connecting plate 350, the sealing gasket body 520 is just plugged into the inlet and outlet of the filter element, and at this time, the sealing gasket body 520 is just abutted against the supporting baffle 430. The setting of the sealing gasket body 520 can further prevent water from flowing upward out of the inlet and outlet of the filter element, so that the water supply filter assembly has good sealing performance.

[0070] like Figure 3 As shown, the finger grip 530 is connected to the top of the cover plate 510. The finger grip 530 is bent in an arc shape, and both ends of the finger grip 530 in the length direction are connected to the cover plate 510. The provision of the finger grip 530 facilitates the operator to apply force to the cover plate 510, thereby facilitating the operator to disassemble and assemble the filter housing cover 500 and the filter housing 300.

[0071] Further, such as Figure 6 As shown, a plug-in groove 521 is provided at the lengthwise end of the sealing pad body 520. The plug-in groove 521 is arranged in a "T" shape.

[0072] The water supply and filtering assembly further includes an auxiliary lifting member 600 . The auxiliary lifting member 600 includes a plug-in frame 610 and a magnetic attraction plate 620 .

[0073] The plug-in frame 610 is detachably connected to the plug-in slot 521. The plug-in frame 610 is also arranged in a "T" shape, and the plug-in frame 610 can be inserted into the plug-in slot 521 along the length direction of the sealing gasket body 520 or can be pulled out from the plug-in slot 521 along the length direction of the sealing gasket body 520.

[0074] The magnetic plate 620 is connected to the bottom of the plug-in frame 610. A magnetic docking layer is provided on the top of the cover plate 510. When the plug-in frame 610 is inserted into the plug-in slot 521, the magnetic plate 620 is located at the bottom of the sealing gasket body 520. The magnetic plate 620 can be set to a certain thickness so that the sealing gasket body 520 can be partially inserted back into the filter inlet and outlet to enable the magnetic plate 620 to be magnetically connected to the top of the cover plate 510.

[0075] When the filter element 400 needs to be updated and replaced, first remove the connector between the cover plate 510 and the connecting plate 350, then lift the cover plate 510 through the finger grip 530, and then pull the sealing gasket body 520 out of the filter element inlet and outlet. Then insert the plug-in frame 610 of the auxiliary lifting member 600 into the plug-in slot 521 of the sealing gasket body 520, so that the bottom of the sealing gasket body 520 has a magnetic suction plate 620. Then insert the sealing gasket body 520 back into the filter element inlet and outlet until the magnetic suction plate 620 is magnetically connected to the top of the cover plate 510, and then remove the old filter element 400 from the shell cavity by magnetic suction. Then install the new filter element 400 into the shell cavity of the filter housing 300, then remove the auxiliary lifting member 600 from the sealing gasket body 520, and finally insert the sealing gasket body 520 back into the filter element inlet and outlet and connect and fix the cover plate 510 and the connecting plate 350 through the connector.

[0076] The provision of the auxiliary lifting member 600 enables the filter element 400 to be easily removed from the shell cavity.

[0077] Furthermore, the water supply meter also includes: a controller and a filtering start button.

[0078] The controller is disposed in the water supply meter body 100 , and the controller is electrically connected to the water consumption statistics component in the water supply meter body 100 .

[0079] The filter start button is connected to the water supply meter body 100 , and the filter start button is electrically connected to the controller.

[0080] After replacing the new filter element 400, press the filter start button on the water supply meter body 100, and the controller will receive a filter start signal. The controller will record the starting water consumption value when the filter start signal is received, and then the controller can know the real-time water consumption value through the water consumption statistics component. When the difference between the real-time water consumption value and the starting water consumption value is equal to the preset water consumption threshold, the controller will send the filter element replacement information to the monitoring platform through the communication module. When the monitoring platform receives the filter element replacement information, it will notify the relevant personnel to replace the filter element 400 of the water supply meter, thereby making the water supply meter more intelligent.

[0081] The above embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary persons in the art to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
