[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figs. 1 to 4 This utility model embodiment provides a horizontal spiral-type water meter movement with self-cleaning function, characterized in that it includes:

[0025] Support assembly 1, wherein the support assembly 1 is provided with an inlet flow hole 101 and an outlet flow hole 102;

[0026] Flange cover assembly 2, which cooperates with bracket assembly 1 to form a transmission chamber, the water inlet flow hole 101 communicates with the transmission chamber, and the water outlet flow hole 102 communicates with the transmission chamber;

[0027] A rectifier assembly 3 is disposed on the support assembly 1, and a flow gap 301 is provided between the rectifier assembly 3 and the support assembly 1. The flow gap 301 is connected to the water inlet flow hole 101.

[0028] Impeller assembly 4 is disposed on the support assembly 1, and the impeller assembly 4 includes blades 401 and impeller shaft 402.

[0029] This utility model provides a horizontal screw-type water meter movement with self-cleaning function, including a bracket assembly 1, a flange cover assembly 2, a rectifier assembly 3, and an impeller assembly 4. When water flows through the water meter, it first passes through the rectifier assembly 3, which guides the water flow smoothly through the impeller assembly; simultaneously, some water flows into the transmission chamber through the flow gap 301. By providing the inlet flow hole 101 and the outlet flow hole 102 on the bracket assembly 1, it is ensured that impurities in the transmission chamber are carried away when the water flows in and out, avoiding the accumulation of dirt and impurities. Under high flow conditions, the flushing effect of the water flow is more obvious, thereby improving the water meter sensitivity, reducing dirt accumulation, improving the accuracy of long-term operation of the water meter, preventing wear or jamming of transmission parts due to long-term dirt, and extending the service life of the water meter.

[0030] In a further embodiment of this invention, the plane formed by the axis of the inlet flow hole 101 and the axis of the outlet flow hole 102 is parallel to the axis of the impeller shaft 402.

[0031] In this embodiment, the plane formed by the axis of the inlet flow hole 101 and the axis of the outlet flow hole 102 is parallel to the axis of the impeller shaft 402, ensuring that the water flow direction from the inlet and outlet flow holes 102 is consistent with the impeller shaft 402, so that the water flow is synchronized with the impeller during the operation of the water meter, reducing turbulence and unnecessary water resistance, and ensuring that the metering accuracy of the water meter is not affected.

[0032] In a further embodiment of this invention, the inlet flow hole 101 and the outlet flow hole 102 constitute a flow hole group, and there are two flow hole groups, which are symmetrically arranged.

[0033] In this embodiment, there are two sets of flow passage holes, symmetrically arranged on both sides of the transmission chamber. This ensures that the water flow is evenly distributed during the inlet and outlet processes, thereby further improving the measurement accuracy of the water meter. The number of inlet flow passage holes 101 and outlet flow passage holes 102 are equal to ensure the flow balance of the water meter during inlet and outlet processes, thus making the measurement more accurate.

[0034] In a further embodiment of this invention, the bracket assembly 1 has a water inlet end and a water outlet end, the water inlet flow hole 101 is disposed at the water inlet end, the water outlet flow hole 102 is disposed at the water outlet end, and the water inlet flow hole 101 and the water outlet flow hole 102 are symmetrically arranged.

[0035] In this embodiment, the inlet flow hole 101 and the outlet flow hole 102 are symmetrically arranged, so that the water flow can be evenly distributed during the inlet and outlet processes, thereby further improving the measurement accuracy of the water meter.

[0036] In a further embodiment of this invention, the diameter of the water inlet orifice 101 is 5 mm.

[0037] In this embodiment, the diameter of the water inlet orifice 101 is 5mm, which ensures that the water flows smoothly into the water meter and that the water flow can fully flush the parts in the transmission chamber, avoid the accumulation of dirt and impurities, prevent the transmission parts from being affected by dirt for a long time, resulting in wear or jamming, and improve the service life of the water meter.

[0038] In a further embodiment of this example, the diameter of the water outlet orifice 102 is 5 mm.

[0039] In this embodiment, the diameter of the outlet flow hole 102 is 5mm, ensuring smooth and unobstructed water flow when leaving the water meter, maintaining the efficient operation of the entire water meter system. The diameter of the outlet flow hole 102 is the same as that of the inlet flow hole 101, both being 5mm. This design allows for uniform water flow distribution during inlet and outlet processes, avoiding wear on water meter components caused by uneven water flow impact. By precisely controlling the size of the inlet and outlet holes, the metering accuracy of the water meter is ensured to be unaffected by water flow fluctuations, thus providing accurate readings under various operating conditions.

[0040] In a further embodiment of this example, the width of the flow gap 301 is 2 mm.

[0041] In this embodiment, the width of the flow gap 301 is 2mm, which ensures the sensitivity and detection accuracy of the water meter. If the width of the flow gap 301 is too small, it cannot ensure that enough water flows into the transmission chamber, thereby achieving the effect of flushing the transmission chamber. If the width of the flow gap 301 is too large, it may lead to a weakening of the water flow impact force, affecting the effect of flushing the transmission chamber.
