[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figure 1-2 , the present utility model provides a technical solution: a sensor valve seat, including a valve seat body 1, an inlet end 2 is connected to one side of the valve seat body 1, a water flow measurement chamber 3 is fixedly connected to the upper end of the valve seat body 1, a flow sensor 4 is threadedly fixed to the upper end of the water flow measurement chamber 3, a connecting pipe 5 is threadedly connected to one side of the water flow measurement chamber 3, one end of the connecting pipe 5 is fixedly connected to an outlet chamber 6, an outlet 7 is fixedly connected to the surface of the outlet chamber 6, and a sealing end cover 8 is fixedly connected to the outer surface of the outlet 7.

[0017] In this embodiment, the flow sensor 4 is fixed to the upper end of the water flow measurement chamber 3 by threading. At this time, the sensor probe of the flow sensor 4 is located inside the water flow measurement chamber 3. Water flows into the interior of the valve seat body 1 through the water inlet end 2 and circulates into the interior of the water flow measurement chamber 3 to measure the water flow. After the measurement, the water flows through the connecting pipe 5 into the interior of the outlet chamber 6. A plurality of connection holes are provided on the surface of the outlet chamber 6, which can be connected to pipes in different directions. Unused outlets can be blocked without the need for adjustment, with a wide range of applications and better adaptability. This design method can adapt to connecting pipes in different directions without the need for matching, with better adaptability and more convenient connection, saving a lot of time.

[0018] Specifically, a filter chamber 9 is provided at the lower end of the valve seat body 1, and a filter element 10 is fixedly connected to the lower end of the filter chamber 9 by threading.

[0019] In this embodiment, through the provided filter element 10, the water flow can be filtered to a certain extent, avoiding the long-term accumulation of impurities in the water on the surface of the flow sensor 4 and affecting the accuracy of the flow sensor 4.

[0020] Specifically, the filter element 10 includes a leak-proof backing plate 11, a turning knob 12, and a threaded fixing rod 17. Threaded rings 18 are provided on the surface of the threaded fixing rod 17. A leak-proof backing plate 11 is fixedly connected to the lower end of the threaded fixing rod 17, and a turning knob 12 is fixedly connected to the lower end of the leak-proof backing plate 11.

[0021] In this embodiment, through the provided turning knob 12, it is convenient to twist the whole for installation and disassembly, facilitating cleaning.

[0022] Specifically, a hollow frame 13 is fixedly connected to the center of the upper end of the threaded fixing rod 17. A top plate 15 is fixedly connected to the upper end of the hollow frame 13. A water outlet hole 16 is fixedly opened at the center of the top plate 15. A filter cotton core 14 is fixedly sleeved on the outer surface of the hollow frame 13.

[0023] In this embodiment, when the water flow flows in from the water inlet end 2, the upper end of the filter chamber 9 is blocked by the top plate 15, so that the water flow must flow through the filter cotton core 14 to reach the hollow frame 13, and then flow through the water outlet hole 16 opened at the center of the top plate 15 into the interior of the hollow frame 13. When passing through the filter cotton core 14, impurities can be filtered and cleaned well, effectively avoiding the influence of impurities in the water on the flow sensor 4. When the water flow measured by the flow sensor 4 changes greatly, the filter element 10 can be screwed to clean the filter cotton core 14. This design method can filter impurities in the water well, avoid affecting the accuracy of the sensor, and at the same time can clean the filter screen in time and be reused, saving more costs.

[0024] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
