[0003] There are still deficiencies in the similar applications as above:

[0004] This filter screen is inserted into the water pipe in an inclined plane structure, and the contact area of the filter screen with the water source is small, so the filtering effect is not ideal. Moreover, the filter screen is only installed at the water inlet pipe part. If there is a sudden water cut-off, after the water in the water pipe flows back, the scale and impurities remaining in the water pipe will backflow into the water meter body, directly affecting the rotation speed of the impeller in the water meter body, affecting the measurement accuracy of the water meter, and reducing the service life of the water meter.

[0005] Therefore, a water meter structure with a filtering function is designed to optimize the above problems. Content of the Utility Model

[0006] The main purpose of the utility model is to provide a water meter structure with a filtering function, including a water meter body.

[0007] One end of the water meter body is provided with a water meter water inlet end, and the other end of the water meter is provided with a water meter water outlet end;

[0008] The inner wall of the water meter water inlet end is sleeved with a first filter housing, and the inner wall of the water meter water outlet end is sleeved with a second filter housing;

[0009] The output end of the water inlet pipe is communicated with the water meter water inlet end through an internal thread fixing ring. The water source enters the water meter body after being filtered by the first filter housing sleeved on the inner wall of the water meter water inlet end, and is filtered by the second filter housing sleeved inside the water meter water outlet end communicated with the other side wall of the water meter body and then conveyed to the water outlet pipe, forming a filtering state.

[0010] Preferably, a sealing joint is installed at the output end of the water inlet pipe. The top of the sealing joint is sleeved on the inner wall of the water inlet end of the water meter. An internal thread fixing ring is sleeved on the outer wall of the water inlet pipe. The internal thread fixing ring rotates and meshes with the external thread ring on the outer wall of the water inlet end of the water meter. The sealing joint connecting the water inlet pipe is fixed on the inner wall of the water inlet end of the water meter;

[0011] A sealing joint connecting the water outlet pipe is sleeved on the inner wall of the water outlet end of the water meter. The internal thread fixing ring sleeved on the outer wall of the water outlet pipe rotates and is sleeved on the outer wall of the external thread ring arranged on the outer wall of the water outlet of the water meter. The internal thread fixing ring fixes the sealing joint connecting the water outlet pipe on the inner wall of the water outlet end of the water meter.

[0012] Preferably, granular activated carbon is sleeved inside the first filter housing;

[0013] Compressed activated carbon and a PP cotton filter element are sleeved inside the second filter housing.

[0014] Preferably, a first filter screen is fixed by screws at the position where the inside of the water meter body communicates with the water inlet end of the water meter. A spring is connected between the first filter screen and the first filter housing. The spring is of a conical structure;

[0017] The top of the rotating shaft penetrates through the top wall of the water meter body and is connected to the bottom of the counting disk.

[0018] Preferably, a protective cover is hinged to the top edge of the water meter body through a hinge shaft. The counting disk is located between the top of the water meter body and the inner end of the protective cover.

[0019] Advantageous technical effects of the present utility model: At both ends of the side wall of the water meter body, the water meter inlet end and the water meter outlet are symmetrically connected. The interfaces of the water meter inlet end and the water meter outlet respectively fix the sealing joints of the inlet pipe and the outlet pipe on the inner walls of the water meter inlet end and the water meter outlet through the internal thread fixing rings sleeved on the outer walls of the inlet pipe and the outlet pipe. The disassembly is more convenient and fast, with strong sealing performance and good fixing effect. The granular activated carbon installed inside the first filter housing sleeved on the inner wall of the water meter inlet end can effectively adsorb impurities in the water source, remove the peculiar smell in the water and dissolve organic substances. The water source filtered by the granular activated carbon enters the water meter body through the first filter screen installed on the side wall of the water meter body. The first filter housing and the first filter screen are connected by a conical structure spring, which can reduce the impact of the water source on the first filter housing during the flowing process and increase the stability of the first filter housing. The impeller sleeved on the outer wall of the rotating shaft inside the water meter body rotates under the impact of the water flow, and the rotation data is transmitted to the counting disk installed at the top of the water meter body through which the rotating shaft penetrates.

[0024] To make the technical solutions of the present utility model clearer and more definite to those skilled in the art, the present utility model will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present utility model are not limited thereto.

[0025] As Figures 1-3 shown, in the present utility model, we fix the sealing joint 19 connected to the output end of the water inlet pipe 18 by screwing the internal thread fixing ring 17 sleeved on the outer wall of the water inlet pipe 18 onto the inner wall of the water inlet end 2 of the water meter. The internal thread fixing ring 17 sleeved on the outer wall of the water inlet pipe 18 is screwed tightly to engage with the external thread provided at the front end of the outer wall of the water inlet end 2 of the water meter. The internal thread fixing ring 17 sleeved on the outer wall of the water outlet pipe 20 is screwed tightly to engage with the external thread provided on one side of the outer wall of the water outlet 3 of the water meter. The fixing effect is good, the sealing performance is strong, and the disassembly is more convenient and fast.

[0026] As Figures 1-2 shown, the granular activated carbon 5 installed in the first filter housing 4 sleeved on the inner wall of the water inlet end 2 of the water meter can quickly adsorb large particle impurities in the water source, remove the peculiar smell in the water and dissolve organic substances. The water source filtered by the first filter housing 4 enters the water meter body 1 through the first filter screen 7 fixed by screws at the adjacent position between the side wall of the water meter body 1 and the water inlet end 2 on one side of the first filter housing 4. The first filter housing 4 sleeved on the inner wall of the water inlet end 2 of the water meter is connected to one side of the first filter screen 7 through the spring 6 with a conical structure. The tension of the spring 6 is used to reduce the impact of the water source on the first filter housing 4 during the flowing process, prevent the first filter housing 4 from hitting the first filter screen 7 connected to one end of the side wall of the water meter body 1 back and forth, and improve the stability of the use of the first filter housing 4 and the first filter screen 7.

[0027] As Figures 1-3 shown, a rotating shaft 10 is fixed on the top of the fixed seat 9 installed in the middle of the inner bottom of the water meter body 1. The impeller 8 sleeved on the outer wall of the rotating shaft 10 rotates automatically through the fluidity of water. The first filter screen 7 and the second filter screen 11 installed on both ends of the side wall of the water meter body 1 by screws are used to isolate the first filter housing 4 and the second filter housing 12 sleeved in the water inlet end 2 and the water outlet 3 of the water meter respectively, which are connected to the side walls of the first filter screen 7 and the second filter screen 11. The first filter screen 7 and the second filter screen 11 can effectively protect the impeller 8 sleeved on the outer wall of the rotating shaft 10 in the water meter body 1 from being adsorbed by scale and impurities;

[0028] One side of the second filter screen 11 is connected to the second filter housing 12 through a spring 6 with a conical structure to relieve the impact of water flow. The compressed activated carbon 13 and the pp cotton filter element 14 installed in the second filter housing 12 absorb heavy metals and fine particles in the water. In case of sudden water cut-off, it can prevent the impurities in the water pipe from flowing back into the water meter body 1 when the water source flows back in time, ensure the accuracy of the rotation of the impeller 8 sleeved on the outer wall of the rotating shaft 10 in the water meter body 1, and extend the service life of the water meter.

[0029] As Figure 1 shown, the top of the rotating shaft 10 installed in the water meter body 1 penetrates through the top wall of the water meter body 1 and is connected to the counting disk 15, enabling the timely viewing of the water meter usage progress. The protective cover 16 hinged to the top edge of the water meter body 1 by a hinge shaft is clamped on the top of the water meter body 1. The protective cover 16 has good compressive resistance and effectively protects the counting disk 15 installed on the top of the water meter.

[0030] The above are only further embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and concept of the present utility model, makes equivalent substitutions or changes, and all belong to the protection scope of the present utility model.
