The filtering device can connect one of its filtering channels to the inlet pipe 101 due to rotation, so that the water in the inlet pipe 101 flows into the filtering channel and then enters the water meter body 1; the driving device is arranged on the inlet pipe 101, the driving device is connected to the filtering device, and the driving device is used to drive the filtering device to rotate; one end of the backwashing pipe 4 is connected to the outlet pipe 102, and the other end of the backwashing pipe 4 is connected to the filtering channel not connected to the inlet pipe 101, and a valve 401 is provided on the backwashing pipe 4.

[0032] The anti-clogging water meter provided in the present embodiment has the following beneficial effects: compared with the prior art, the anti-clogging water meter provided in the present embodiment filters tap water through the filter channel on the filter device by setting a filter device, thereby preventing impurities from being deposited in the water meter, thereby greatly improving the service life of the water meter; at the same time, by setting a drive device and a backwashing pipe 4, the two filter channels can be used alternately, and when one of them is in use, the other can be backwashed to prevent the filter channel from being blocked.

[0033] like Figure 1 As shown, the water inlet pipe 101 includes a first inlet pipe 103 and a second inlet pipe 104, the first inlet pipe 103 is connected to the water meter body 1, and the second inlet pipe 104 is used to connect to the external water supply pipeline, and the first inlet pipe 103 and the second inlet pipe 104 are arranged at intervals. The filtering device includes a filter disc 2, the filter disc 2 has a first end face 201 and a second end face 202, the first inlet pipe 103 is pressed against the first end face 201, and the second inlet pipe 104 is pressed against the second end face 202, and the filter channel is arranged on the filter disc 2, and the two filter channels are arranged symmetrically, and the symmetry center of the two filter channels is the center of the filter disc 2. When the filter disc 2 rotates, the first inlet pipe 103 and the second inlet pipe 104 are always pressed against the filter disc 2 to prevent water leakage. At the same time, the two filter channels are arranged symmetrically, and the switching of the filter channel connected to the water inlet pipe 101 can be completed by rotating the filter disc 2 180 degrees.

[0034] In this embodiment, a mounting plate 105 is provided on both the first inlet pipe 103 and the second inlet pipe 104. A pivot hole is provided on the mounting plate 105. A pivot shaft 203 is provided at both ends of the filter disc 2. The pivot shaft 203 is coaxially arranged with the filter disc 2, and the pivot shaft 203 is inserted into the pivot hole. The arrangement of the mounting plate 105 can facilitate the rotation of the filter disc 2, and further facilitate the switching of the filter channel connected to the water inlet pipe 101.

[0035] Preferably, the driving device includes a first stepper motor 3, which is arranged on one of the mounting plates 105. The pivot shaft 203 is connected to the power output end of the first stepper motor. Each time the first stepper motor 3 is started, it drives the filter disc 2 to rotate 18 degrees, thereby completing the switching of the filter channel connected to the water inlet pipe 101.

[0036] Combination Figure 3 and Figure 4 As shown, the filter channel includes a through hole 204 and a filter assembly 205. The diameter of the through hole 204 is the same as the inner diameter of the water inlet pipe 101. The filter assembly 205 is arranged in the through hole 204 to filter the water flowing through the hole 204. The arrangement of the filter assembly 205 can facilitate the filtering of tap water.

[0038] In addition, the two dirt storage tanks 208 are arranged symmetrically, and the symmetry center of the two dirt storage tanks 208 is the center of the second end surface 202, and when the filter channel is connected to the water inlet pipe 101, the corresponding dirt storage tank 208 is arranged below the filter assembly 205. When in use, once the filter channel connected to the water inlet pipe 101 is switched, the filter channel originally connected to the water inlet pipe 101 is arranged on one side of the water inlet pipe 101, the dirt storage tank 208 rises above the through hole 204, and the opening of the dirt storage tank 208 faces downward, and the dirt in the dirt storage tank 208 is discharged under the action of gravity, so that all impurities can be taken away during backwashing.

The mounting frame 206 is annular, and the outer diameter of the mounting frame is the same as the diameter of the through hole 204. The mounting frame 206 is arranged on the side wall of the through hole 204, and the filter screen 207 is arranged on the mounting frame 206. The arrangement of the mounting frame 206 can facilitate the fixing of the filter screen 207 to the side wall of the through hole 204.

[0040] Finally, the chamfering of one end of the installation frame close to the second end surface 202 can prevent impurities from accumulating in the installation frame 206 .

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
