These water meters usually contain a module box, which contains a circuit board, a display panel and other electronic components for data collection, processing and display. However, the ultrasonic water meter module box in the prior art has obvious deficiencies in waterproof performance. Since the use environment of water meters is often humid and even directly in contact with water sources, the waterproof performance of the module box is directly related to the reliability and service life of the water meter.

[0003] Existing module box designs usually use simple sealing structures, such as rubber gaskets or sealants. These methods may be effective in the short term, but over time, the sealing materials may gradually lose their waterproof effect due to aging, wear or environmental factors (such as temperature changes, chemical corrosion). Once moisture penetrates into the module box, it may cause short circuits, corrosion or damage to sensitive electronic components such as circuit boards and display panels, thus affecting the normal operation of the water meter and even causing data loss and inaccurate measurements.

[0006] The beneficial effects of the present invention are as follows: the module box structure of the ultrasonic water meter provided by the present invention realizes a multi-level, three-dimensional waterproof structure by setting the first inner barrier and the first outer barrier at the edge of the upper shell, and setting the second inner barrier and the second outer barrier at the edge of the lower shell.

[0013] From the above description, it can be seen that the beneficial effect of the present invention is that: by setting the first inner barrier 11 and the first outer barrier 12 at the edge of the upper shell 1, and setting the second inner barrier 21 and the second outer barrier 22 at the edge of the lower shell 2, a multi-level, three-dimensional waterproof structure is realized. This structural design significantly improves the sealing performance of the module box, effectively preventing external moisture from invading the interior of the installation cavity 3 through the shell gap; the inner side walls of the first inner barrier 11 and the second inner barrier 21 conflict with each other, and the inner side walls of the first outer barrier 12 and the second outer barrier 22 conflict with each other, forming a tight physical barrier, and enhancing the module box's ability to block moisture; this design not only improves the waterproof level of the module box, but also enhances the protection of sensitive electronic components such as internal circuit boards and display panels, reduces the risk of damage caused by moisture intrusion, thereby extending the service life of the water meter and improving its reliability; in addition, this structural design also takes into account the mechanical stability of the module box, and through the reasonable layout and conflict relationship of the barrier parts, the overall rigidity and impact resistance of the module box are enhanced, so that it can adapt to various harsh installation environments and conditions.

[0014] Furthermore, it also includes a first sealing member 4 , which is located between the first outer blocking portion 12 and the first inner blocking portion 11 , and the second outer blocking portion 22 is in contact with the first sealing member 4 .

[0015] As can be seen from the above description, the first sealing member 4 is located between the first outer barrier 12 and the first inner barrier 11, adding an additional waterproof layer, further improving the sealing performance of the module box. This design helps to form a more reliable seal between the barrier parts to prevent moisture penetration.

[0016] Furthermore, the first sealing member 4 is made of nitrile rubber, hydrogenated nitrile rubber, EPDM rubber, silicone rubber, chloroprene rubber, fluororubber, tetrafluoroethylene rubber, fluorosilicone rubber, perfluororubber, polytetrafluoroethylene rubber or acrylate rubber.

[0017] From the above description, it can be seen that the above materials all have good weather resistance, chemical resistance and aging resistance. The most suitable sealing material can be selected according to different usage environments and requirements to ensure long-term and effective waterproof performance.

[0018] Furthermore, a second sealing member 5 is included. The second sealing member 5 is located between the second outer barrier portion 22 and the second inner barrier portion 21 , and the first inner barrier portion 11 is in contact with the second sealing member 5 .

[0023] From the above description, it can be seen that the design of the hydrophobic holes allows the moisture that may accumulate inside to be discharged through the hydrophobic holes, reducing the internal pressure and avoiding damage to the seal due to excessive pressure, thereby improving the durability and reliability of the module box.

[0024] Furthermore, the diameter of the end of the hydrophobic hole close to the first inner barrier portion 11 is smaller than the diameter of the end of the hydrophobic hole away from the first inner barrier portion 11 .

[0025] From the above description, it can be seen that the diameter of the hydrophobic hole is designed to be small at one end and large at the other end, which helps to guide the water flow in one direction, prevent external moisture from flowing back into the module box, and promote the discharge of internal moisture.

[0026] Furthermore, the cross section of the hydrophobic hole is conical.

[0027] From the above description, it can be seen that the cross-section of the hydrophobic pore is conical, and this shape helps to optimize water flow dynamics, improve hydrophobic efficiency, reduce the retention of water molecules in the pore, and reduce the risk of water penetration.

[0028] Furthermore, a water-absorbing filler is provided in the hydrophobic hole.

[0029] From the above description, it can be known that arranging a water-absorbing filler in the hydrophobic hole can absorb the moisture discharged through the hydrophobic hole, prevent the moisture from overflowing, keep the outside of the module box dry, and reduce the impact on the surrounding environment.

[0030] Furthermore, the water-absorbing filler is a water-absorbing resin.
