[0023] Furthermore, the control box upper box 7 is made of transparent ABS plastic material, and a cylindrical insertion structure is adopted between the control box lower box 2 and the control box upper box 7.

[0024] Furthermore, the flip cover 5 is arranged directly above the counter assembly 10, and the flip cover 5 is made of PVC material. When viewing the mechanical character wheel reading part, the PVC rotating cover can be rotated clockwise or counterclockwise, and the entire counter assembly 10 can be viewed through a transparent window.

[0025] Furthermore, the visual window 6 is arranged just above the circuit board box 17, and the water ingress into the circuit board can be observed through the transparent control box upper box 7, which is convenient for inspection and judgment.

[0026] Furthermore, the circuit board 17 is sealed in the groove inside the control box upper box 7 by glue filling to form a waterproof sealed cavity, so that the water meter electronic components are completely sealed inside, preventing the water meter from having a service life due to moisture or water vapor, and greatly improving the waterproof performance of the water meter.

[0027] Furthermore, a plurality of sealing rubber grooves are reserved on the outer circumference of the rubber plug 12, and the rubber can be applied for secondary sealing. This is convenient for repairing and replacing the battery, and can strictly ensure the waterproof sealing performance of the battery compartment. The battery compartment has the characteristics of strong waterproof performance, simple structure and convenient replacement.

[0028] Furthermore, the water meter base case adopts an integrated 304 stainless steel case design, which is safe, environmentally friendly, has no secondary pollution, is acid and alkali resistant, will not produce corrosion and exudate at high or low temperatures, is safe and reliable, and meets food hygiene standards.

[0029] The utility model buckles the circuit board box with the control box lower box 2 into one body through a cylinder, connects and fixes the circuit board box and the control box lower box 2 through screws, and embeds the circuit board box in the housing of the control box upper box 7.
