Description

Technical Field

[0001] The utility model relates to the technical field of water meter cores, in particular to an insertion-type water meter core. Background Art

[0002] The water meter movement is an instrument for measuring water flow, mostly the cumulative flow of water. The actual water consumption of each household is determined by the movement. However, after long-term immersion in water, the filter will be eroded by scale, and the filter holes will be attached by scale, which will greatly reduce the diameter of the filter holes. The detection end is set in the filter. After the filter holes are attached by scale, the amount of water that can pass through the filter holes per unit flow is reduced, which greatly reduces the efficiency and authenticity of the detection. Therefore, we propose an insertable water meter movement. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Example:

[0023] See also Figure 1-4 The utility model provides a technical solution for an insertable water meter movement: comprising a movement housing 1; a docking joint 2 is provided at the bottom of the movement housing 1, a filter cover 3 is provided at the bottom of the docking joint 2, water filter holes are evenly opened on the filter cover 3, and the water filter holes are elliptical; a cleaning ring 4 is sleeved on the outer side of the docking joint 2 and the filter cover 3, and the cleaning ring 4 includes an upper docking ring 7 and a lower docking ring 8;

[0024] The filter cover 3 of the docking head 2 is provided with a mounting groove 6, and the upper docking ring 7 is rotatably sleeved in the mounting groove 6 of the docking head 2; the lower mounting groove 6 is provided at the bottom of the filter cover 3 and does not contact the water filter eye, and the lower docking ring 8 is rotatably sleeved in the mounting groove 6 of the filter cover 3;

[0025] Gear grooves are equidistantly provided in the upper docking ring 7, and a drive motor 9 is provided in the inner cavity of the docking head 2. The drive motor 9 is installed on the side close to the gear groove. A transmission gear is provided on the top of the drive motor 9, and the transmission gear meshes outward in the gear groove.

[0026] Furthermore, the diameter of the filter cover 3 is the same as that of the docking head 2, and three cleaning sheets 5 are installed between the upper docking ring 7 and the lower docking ring 8;

[0027] Furthermore, the cleaning sheet 5 is pressed inwardly against the outer wall of the filter cover 3, and the diameter of the cleaning sheet 5 is half the length of the water filter eye;

[0028] Furthermore, a water disturbance groove 10 is equidistantly provided on one side of the cleaning sheet 5 close to the filter cover 3. The water disturbance groove 10 is a rectangular groove, and the inner cavity of the water disturbance groove 10 is concave inward in a trapezoidal shape. When the water disturbance groove 10 rotates, it can stimulate the surrounding water flow, thereby disturbing the water flow around the water filter eye. The fluctuation of the water flow can shake off some of the scale attached to the side wall.

[0029] Furthermore, the upper docking ring 7 and the lower docking ring 8 are both snapped into the mounting groove 6, and the depth of the snapping is 1-2 mm;

[0030] Furthermore, the movement of this solution has a scale cleaning function. The interior of the movement housing 1 is provided with electrical components, and the filter cover 3 is provided with a detection head. This part is the existing technology, so it will not be described in detail.

[0031] Furthermore, after long-term use, a lot of scale will remain on the mesh of the filter cover 3, which can easily clog the water filter, slowing down the water intake efficiency of the filter cover and affecting the authenticity of the detection.

[0032] Furthermore, a cleaning ring is provided on the outside of the filter cover 3. The cleaning ring 4 includes an upper and a lower docking ring (corresponding to the numbers 7 and 8 in the figure). A gear groove is provided on the inner side of the upper docking ring 7. A transmission gear is provided on the top of the drive motor 9. The transmission gear and the gear groove are engaged with each other. The cleaning ring 4 is driven to rotate by the drive motor 9, and the lower docking ring 8 is rotatably installed on the bottom of the filter cover 3. When the cleaning ring 4 rotates, the cleaning sheet 5 is driven to rotate synchronously. The cleaning sheet 5 rotates continuously around the filter cover 3, and the scale at the water filter eye is peeled off by scraping, which can effectively reduce the problem of scale clogging the water filter eye.

[0033] Furthermore, a delay switch is provided in the movement housing 1, and the delay switch is electrically connected to the drive motor 9. By presetting the time interval, the drive motor 9 can be restarted at intervals. The interval restart can reduce energy waste and increase the service life of the drive motor 9.

[0034] Furthermore, the driving motor 9 is a slow torque motor, which drives the cleaning ring 4 to rotate slowly to avoid excessively fast rotation speed affecting the detection efficiency;

[0035] Furthermore, the water filter uses an elliptical aperture. The elliptical shape has a larger contact area, which increases the water filtration efficiency. More water can pass through within a unit flow rate, and the processing efficiency is higher.
