[0034] Figure 1 A schematic diagram of the controller structure provided in the embodiment of the present application; Figure 1 As shown: the controller includes: a shell 10, a first glue pouring cavity 100, a second glue pouring cavity 110, and a battery compartment 120 are formed inside the shell 10; a first partition 130 is arranged between the first glue pouring cavity 100 and the second glue pouring cavity 110; the first partition 130 is provided with a first wire hole 131; a circuit board 140 is arranged inside the first glue pouring cavity 100; a second partition 150 is arranged between the second glue pouring cavity 110 and the battery compartment 120; the second partition 150 is provided with a second wire hole 151; the battery compartment 120 is used to install the battery 121; the first glue pouring cavity 100 is connected with the second glue pouring cavity 110 through the first wire hole 131, and the second glue pouring cavity 110 is connected with the battery compartment 120 through the second wire hole 151;
[0035] The circuit board 140 is connected to the battery 121 installed in the battery compartment 120 through a wire, so that the battery 121 supplies power to the circuit board 140; one end of the wire is fixedly connected to the circuit board 140, and the other end of the wire passes through the first wire hole 131 in sequence, passes through the second glue filling cavity 110, and passes through the second wire hole 151 to be connected to the battery 121;
[0036] The first glue potting cavity 100 and the second glue potting cavity 110 are filled with sealing colloid, and the sealing colloid immerses the upper edge of the first wire hole 131, so that the first glue potting cavity 100 and the battery compartment 120 are isolated by the second glue potting cavity 110, and the circuit board 140 is sealed and protected.
[0037] The controller includes a shell 10, and the shell 10 has a first glue filling chamber 100, a second glue filling chamber 110, and a battery compartment 120; wherein the first glue filling chamber 100 is separately arranged from the battery compartment 120. A circuit board 140 is arranged inside the first glue filling chamber 100, and the battery compartment 120 is used to install a battery 121. In actual application, the battery 121 supports replaceable, and the battery 121 can be installed in the battery compartment 120, and can also be removed from the battery compartment 120 for replacement. A first partition 130 is arranged between the first glue filling chamber 100 and the second glue filling chamber 110, and the first partition 130 has a first wire passing hole 131; a second partition 150 is arranged between the second glue filling chamber 110 and the battery compartment 120; the second partition 150 has a second wire passing hole 151; the first glue filling chamber 100 is connected with the second glue filling chamber 110 through the first wire passing hole 131, and the second glue filling chamber 110 is connected with the battery compartment 120 through the second wire passing hole 151;
[0038] The wires of the battery 121 in the battery compartment 120 pass through the second wire hole 151, through the second glue potting cavity 110, and then through the first wire hole 131 to connect to the circuit board 140. Exemplarily, a group of wires are connected to the upper end of the battery 121, one wire is connected from the positive electrode of the battery 121, and the other wire is connected from the negative electrode of the battery 121; the two wires pass through the second wire hole 151 at the same time, through the second glue potting cavity 110, and then through the first wire hole 131 to connect to the circuit board 140, and are welded to the circuit board 140. Exemplarily, the inside of the first glue potting cavity 100 and the second glue potting cavity 110 is filled with sealing colloid, and the sealing colloid submerges the upper edge of the first wire hole 131; so that the first glue potting cavity 100 and the battery compartment 120 are isolated through the second glue potting cavity 110, and the circuit board 140 is sealed and protected. It should be noted that the first glue filling cavity 100 is connected to the second glue filling cavity 110, the second glue filling cavity 110 is connected to the battery compartment 120, and the first glue filling cavity 100 and the battery compartment 120 are isolated to protect the circuit board 140 in the first glue filling cavity 100. In one example, the glue filling method of the first glue filling cavity 100 and the second glue filling cavity 110 is not limited, and the two cavities can be glued separately. The sealing colloids for the glue filling in the first glue filling cavity 100 and the second glue filling cavity 110 can be the same or different; for example, a sealing colloid with higher sealing performance is used in the second glue filling cavity 110, and a sealing colloid with slightly lower sealing effect is used in the first glue filling cavity 100 to reduce costs. The sealing colloid in this example can be any type of sealing colloid, and this example does not limit the type of sealing colloid. Specifically, the sealing colloid is a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain adhesiveness; it is mainly used to fill the configuration gap to achieve a sealing effect and prevent the leakage of substances such as gas, liquid or solid. Sealing colloids usually have good waterproof properties, can effectively prevent moisture penetration, and protect sealed objects from moisture erosion. The sealant also has a certain degree of adhesion, which can tightly bond the same or different materials together to form a stable structure. The height of the sealing colloid is to immerse the circuit board 140 inside the first glue filling cavity 100, and at the same time exceed the upper edge of the first wire hole 131. In this way, the protection of the circuit board 140 is achieved, and when the battery 121 in the battery compartment 120 is replaced, the protectiveness of the circuit board 140 inside the controller will not be damaged. In this example, by designing the position of the first wire hole and filling the first glue filling cavity, the circuit board can also have a higher degree of protection when the battery is replaced, thereby improving the reliability of the controller protection.
[0039] Figure 2 This is a top view of the controller of this application; Figure 2 As shown, a first partition 130 is disposed between the first glue potting cavity 100 and the second glue potting cavity 110 ; the circuit board 140 is disposed in the first glue potting cavity 100 ; and the second glue potting cavity 110 is connected to the battery compartment 120 .
[0040] As an example, the upper edge of the first wire hole 131 is lower than the lower edge of the second wire hole 151 ; the sealing glue layer in the second glue potting cavity 110 is higher than the upper edge of the first wire hole 131 and lower than the lower edge of the second wire hole 151 .
[0041] Specifically, the height of the first wire hole 131 should be lower than the height of the second wire hole 151, and should be below. In actual applications, when water leaks out of the battery compartment 120, since the first wire hole 131 is located lower than the second wire hole, water will not flow into the first glue filling cavity 100 through the first wire hole 131, causing damage to the circuit board 140. When glue is being poured into the first glue filling cavity 100, the sealing colloid flows into the second glue filling cavity 110 through the first wire hole 131. At this time, the height of the sealing colloid layer in the second glue filling cavity 110 is higher than the upper edge of the first wire hole 131, and lower than the lower edge of the second wire hole 151. This prevents water from leaking out of the battery compartment 120, as the water first flows into the second glue filling cavity 110, and does not affect the circuit board 140 in the first glue filling cavity 100. In this example, by designing the position of the first wire passing hole between the first glue filling cavity and the second glue filling cavity, and the position of the second wire passing hole between the second glue filling cavity and the battery compartment, and the height of the first wire passing hole is lower than the height of the second wire passing hole, water is prevented from leaking into the first glue filling cavity and affecting the circuit board, thereby improving the reliability of circuit board protection.
[0042] As another example, the bottom of the second potting cavity 110 is lower than the lower edge of the first wire passing hole 131 .
[0043] Specifically, the depth of the bottom of the second glue potting cavity 110 is lower than the lower edge of the first wire hole 131, and is located below the first wire hole 131; in actual application, when water leaks out of the battery compartment 120, the water can sink to the bottom of the bottom of the second glue potting cavity 110 and will not flow into the first glue potting cavity 100. In this example, the depth of the bottom of the second glue potting cavity is lower than the lower edge of the first wire hole, which improves the reliability of circuit board protection.
[0044] As another example, the controller further includes an upper cover 160 ; the upper cover 160 is connected to the housing 10 in a covering manner.
[0045] Specifically, the upper end of the entire controller further includes an upper cover 160 , which can be opened and closed; and when closed, the upper cover 160 covers the first glue filling cavity 100 and the battery compartment 120 .
[0046] As another example, one of the housing 10 and the upper cover 160 is provided with a sealing protrusion, and the other is provided with a sealing groove; the sealing protrusion and the sealing groove are plugged into each other; the housing 10 and the upper cover 160 are sealed by the sealing protrusion and the sealing groove.
[0047] Specifically, in combination with the above example, a sealing protrusion or a sealing groove is provided on the housing 10 of the controller, and a sealing groove or a sealing protrusion is provided on the upper cover 160 of the controller that cooperates therewith. When the upper cover 160 is closed, the housing 10 and the upper cover 160 are sealed by the sealing protrusion and the sealing groove. In this example, by providing the sealing protrusion and the sealing groove, the controller is further sealed on the basis of the glue sealing, and the reliability of the protection of the controller is further improved.
[0048] As another example, the upper cover 160 and the housing 10 are fixedly connected by screws.
[0049] After the upper cover 160 and the housing 10 are sealed, they are fixedly connected by screws to fix the upper cover 160 and the housing 10 of the controller. It should be noted that the present application does not limit the connection method of the upper cover 160 and the housing 10. For example, the upper cover 160 and the housing 10 can also be connected by gluing, ultrasonic welding, etc. In this example, after the upper cover and the housing are sealed, they are fixed by screws, which further improves the reliability of the controller protection.
[0050] Furthermore, the upper cover 160 is provided with a through hole; the controller further includes: a battery cover 161;
[0051] The battery cover 161 is detachably covered on the through hole. When the battery cover 161 is covered on the through hole, the battery compartment 120 is sealed.
[0052] Exemplarily, the controller upper cover 160 mentioned above has a through hole on the upper cover 160. The battery cover 161 can be detachably covered on the opened through hole. The battery cover 161 corresponds to the position of the battery compartment 120. When the battery cover 161 is covered on the through hole, the battery compartment 120 is in a sealed state. In this example, the sealing of the battery compartment 120 is ensured by opening a through hole on the upper cover 160 and installing the battery cover 161 on the through hole. At the same time, when replacing the battery 121, it is only necessary to open the battery cover 161 without destroying the stability of the controller.
[0053] As yet another example, the battery cover 161 and the through hole have a threaded structure, and the battery cover 161 is connected to the through hole through threads.
[0054] Specifically, the battery cover 161 and the through hole have a threaded structure, and the battery cover 161 and the through hole are connected by threads. In practical applications, the threaded connection can firmly connect two or more components through the screwing action of the thread, and has high connection strength and stability. In this example, the through hole of the battery cover 161 and the upper cover 160 is connected by threads, and the structure is more stable and has good sealing.
[0055] In conjunction with any of the preceding examples, Figure 3 This is an exploded diagram of the overall structure of the controller of this application; Figure 3 As shown, the controller includes a housing 10, a sealing protrusion is provided on the top of the housing 10, and a sealing groove is provided on the upper cover 160 matched therewith. The upper cover 160 of the controller is sealed with the housing 10 by the sealing protrusion and the sealing groove, and fixed by screws. A through hole is formed in the upper cover 160, and a battery cover 161 is detachably covered on the through hole. A circuit board 140 is provided inside the housing 10, and the circuit board 140 is provided inside the first glue filling cavity 100. A first partition 130 is provided between the first glue filling cavity 100 and the second glue filling cavity 110, and a first wire hole 131 is provided at the bottom of the first partition 130, and a battery 121 is installed inside the battery compartment 120.
[0056] Figure 4 A partial cross-sectional schematic diagram of the controller of this application; Figure 4 As shown, the controller housing 10 and the upper cover 160 are sealed and connected. After the first glue potting cavity 100 where the circuit board 140 is located is filled with glue, the sealing glue layer submerges the circuit board 140 and exceeds the upper edge of the first wire hole 131.
[0057] As yet another example, the circuit board 140 is fixedly installed in the housing 10 by means of positioning columns and screws.
[0058] The circuit board 140 of this example is installed in the housing 10 of the controller. A positioning column is provided at the lower end of the circuit board 140, and the upper end is fixed to the inside of the housing 10 by screws and positioning columns. In this example, the circuit board is fixed and sealed with the aforementioned sealing colloid, which further improves the reliability of circuit board protection.
[0059] This embodiment also provides a water meter, including the controller and the base meter in any embodiment.
[0060] The base meter is connected to the controller. In practical applications, the main function of the base meter is to accurately measure the water flow. Specifically, the base meter uses its internal mechanical structure or electronic components to accurately measure the water flow through the water meter to ensure accurate recording of the user's water consumption; it can work stably in various environments to ensure long-term accurate flow measurement. The controller can monitor the water consumption of the water meter in real time and automatically record the water consumption data, which greatly improves the efficiency of meter reading and reduces the errors and costs of manual meter reading. Through network connection, the water meter controller can realize remote control of the water meter, such as remotely switching water valves, adjusting water flow, etc., which provides great convenience for management personnel. The controller can collect and manage water meter data, including real-time monitoring of water meter data, statistics of water consumption, water consumption analysis, etc., which are of great significance for water resource management and decision-making. In this example, the base meter is connected to the controller to achieve the purpose of accurately measuring water consumption of the water meter.
