[0013] When the second cover is in the second state, the second cover is misaligned with the second pick-up / placement port so that the second pick-up / placement port is opened.

[0014] In some embodiments, the bottom shell further has a first loading and unloading port, which communicates with the first cavity. The top cover is disposed at the first loading and unloading port, and the first cover plate is movably connected to the second cover plate. The first loading and unloading port and the second loading and unloading port face the same direction.

[0015] In some embodiments, the first cover plate has a positioning cavity, and when the second cover plate is in a first state, a portion of the first cover plate is located within the positioning cavity.

[0016] In some embodiments, the first cover plate has a first guide portion and the second cover plate has a second guide portion, the first guide portion and the second guide portion being guided and engaged so that the second guide portion can move relative to the first guide portion in a first direction or a second direction that are opposite to each other;

[0017] When the second guide moves along the first direction, the second cover plate switches from the first state to the second state;

[0018] When the second guide moves along the second direction, the second cover plate switches from the second state to the first state.

[0019] In some embodiments, the first guide portion is a guide groove formed on the side wall of the first cover plate, and the second guide portion is a guide block disposed on the edge of the second cover plate.

[0020] In some embodiments, the first cover plate has a first snap-fit ​​portion, and the second cover plate has a second snap-fit ​​portion;

Subsequently, by moving the second cover plate relative to the first cover plate to the first state, the second access port is sealed by the second cover plate, and the battery can be enclosed in the second cavity. During the battery replacement process, the first cover plate always seals the first access port, avoiding the need to disassemble the second cover plate from the bottom shell and avoiding exposure of the metering component. The second cover plate is always connected to the first cover plate, thus eliminating the need to disassemble and install the first cover plate, making the battery replacement process simple and convenient.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0052] A water meter controller connects to the water meter's meter head and calculates water consumption based on the meter's readings. The controller primarily consists of a main body and a battery, which powers the main body. The battery needs to be replaced after prolonged use and depletion.

[0053] The current water meter controller has its battery located inside. When replacing the battery, multiple bolts need to be removed to remove the battery cover, which makes the battery replacement process cumbersome and inconvenient.

[0054] In the water meter controller proposed in this application, the metering component and the battery are respectively disposed in the first cavity and the second cavity of the bottom shell. The first cover plate seals the first access port, so that the metering component can be enclosed in the first cavity, thus protecting the metering component. The second cover plate is movably connected to the first cover plate, allowing the second cover plate to move relative to the first cover plate, switching between a first state and a second state. When the second cover plate moves relative to the first cover plate to the second state, the second access port is opened, and the battery in the second cavity can be removed through the second access port, and the replacement battery can be installed in the second cavity through the second access port. Subsequently, by moving the second cover plate relative to the first cover plate to the first state, the second access port is sealed by the second cover plate, and the battery can be enclosed in the second cavity. During the battery replacement process, the first cover plate always seals the first access port, avoiding the need to disassemble the second cover plate from the bottom shell and avoiding exposure of the metering component. The second cover plate is always connected to the first cover plate, thus eliminating the need to disassemble and install the first cover plate, making the battery replacement process simple and convenient.

[0055] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0056] This application discloses a water meter controller, with reference to... Figures 1 to 2 As shown, it includes a base shell 100, a metering component 400, a battery 500, a first cover plate 200, and a second cover plate 300. This water meter controller can be used in wireless earphones.

[0057] The base shell 100 is the basic component of the water meter controller of this application, and it can provide an installation base for at least some other components of the water meter controller. The base shell 100 can be made of polymer, making it relatively lightweight. Alternatively, the base shell 100 can be made of metal, which would provide better structural strength, resulting in improved durability and reliability.

[0058] The bottom shell 100 has a first cavity 110, which is a hollow structure within the bottom shell 100. The bottom shell 100 also has a first access port 120, which can be located on the surface of the bottom shell 100 and communicates with the first cavity 110, allowing the first cavity 110 to communicate with the outside of the bottom shell 100 through the first access port 120. The metering component 400 is disposed within the first cavity 110 of the bottom shell 100. Specifically, when assembling the water meter controller of this application, the metering component 400 can be installed in the first cavity 110 of the bottom shell 100 through the first access port 120.

[0059] The bottom shell 100 also has a second cavity 130, which is a hollow structure within the bottom shell 100 and is separated from the first cavity 110. The bottom shell 100 also has a second access port 140, which can be located on the surface of the bottom shell 100 and communicates with the second cavity 130, allowing the second cavity 130 to communicate with the outside of the bottom shell 100 through the second access port 140. The battery 500 is disposed within the second cavity 130 of the bottom shell 100. Specifically, when assembling the water meter controller of this application, the battery 500 can be installed in the second cavity 130 of the bottom shell 100 through the second access port 140.

[0060] Battery 500 is electrically connected to metering component 400, enabling battery 500 to power metering component 400. Metering component 400 can also be electrically connected to the meter head of the water meter, allowing signals detected by the sensor inside the meter head to be transmitted to metering component 400, which can then calculate the actual water flow data based on the electrical signals transmitted from the meter head.

[0061] The first cover plate 200 is detachably disposed on the bottom shell 100, and the first cover plate 200 blocks the first access port 120 of the bottom shell 100. In this way, the metering component 400 can be enclosed in the first cavity 110 by the first cover plate 200, so that the bottom shell 100 and the first cover plate 200 can surround the metering component 400 to fully protect the metering component 400. Specifically, when assembling the water meter controller of this application, the metering component 400 can be installed in the first cavity 110 through the first access port 120 first, and then the first cover plate 200 can be connected to the bottom shell 100 to seal the metering component 400 in the first cavity 110.

[0062] The second cover plate 300 is movably connected to the first cover plate 200, allowing the second cover plate 300 to move relative to the first cover plate 200. This allows the relative position of the second cover plate 300 and the first cover plate 200 to change, enabling the second cover plate 300 to switch between a first state and a second state. When the second cover plate 300 moves to the second state relative to the first cover plate 200, the second access port 140 of the bottom shell 100 is misaligned with the second cover plate 300, ensuring that the second cover plate 300 does not obstruct the second access port 140. The second access port 140 is then opened, allowing the battery 500 inside the second cavity 130 of the bottom shell 100 to be removed through the second access port 140, and the replacement battery 500 to be installed into the second cavity 130 through the second access port 140.

[0063] When the second cover plate 300 moves to the first state relative to the first cover plate 200, the second take-out port 140 of the bottom shell 100 is opposite to the second cover plate 300, so that the second cover plate 300 blocks the second take-out port 140 and the second take-out port 140 is closed, so that the battery 500 can be sealed in the second cavity 130 of the bottom shell 100.

[0064] Therefore, when it is necessary to replace the battery 500 in the second cavity 130 of the bottom housing 100, the second cover 300 can be moved relative to the first cover 200 to switch to a second state, allowing the battery 500 to be removed and a new battery 500 to be installed in the second cavity 130. Subsequently, the second cover 300 can be moved relative to the first cover 200 to a first state, blocking the second access port 140 and sealing the battery 500 within the second cavity 130. During the battery 500 replacement process, the first cover 200 remains connected to the bottom housing 100 to block the first access port 120, eliminating the need to disassemble the first cover 200 from the bottom housing 100 and preventing the metering component 400 from being exposed. The second cover 300 also remains connected to the first cover 200, avoiding the need to disassemble and reinstall the second cover 300, thus making the battery 500 replacement process simple and convenient.

[0065] In addition, a lead seal 900 can be provided at the connection between the first cover plate 200 and the bottom shell 100, so that the lead seal 900 will not be damaged when the battery 500 is replaced, thus avoiding the risk of the metering component 400 being damaged or modified.

[0066] In some implementations, reference Figure 1As shown, to make the structure of the water meter controller of this application more compact, the orientation of the first access port 120 and the second access port 140 can be set to be the same, so that the first cover plate 200 and the second cover plate 300 can be located on the same side of the bottom shell 100, making the structure of the water meter controller of this application more compact. In addition, both the first cover plate 200 and the second cover plate 300 can be flat plate structures, which simplifies the structure of the first cover plate 200 and the second cover plate 300, thereby reducing the cost of the water meter controller of this application.

[0067] Specifically, the thickness direction of the metering component 400 in this application can be set to be consistent with the orientation of the first loading / unloading port 120, so that the metering component 400 can be laid flat in the first cavity 110 of the bottom shell 100. The battery 500 can be a cylindrical structure, and the direction of the axis of the battery 500 can be set to be consistent with the orientation of the second loading / unloading port 140.

[0068] In some implementations, reference Figure 4 As shown, the first cover plate 200 of this application may also be provided with a positioning cavity 210, which is also a cavity structure within the first cover plate 200. When the second cover plate 300 is in the first state, part of the second cover plate 300 is located within the positioning cavity 210 of the first cover plate 200. In this way, the inner wall of the positioning cavity 210 can limit the second cover plate 300, making the structure more stable when the second cover plate 300 is in the first state.

[0069] Specifically, when the second cover plate 300 switches from the first state to the second state, the second cover plate 300 can move in a direction away from the positioning cavity 210, causing the second cover plate 300 to detach from the positioning cavity 210. When the second cover plate 300 switches from the second state to the first state, the second cover plate 300 can move in a direction toward the positioning cavity 210, causing a portion of the second cover plate 300 to enter the positioning cavity 210.

[0070] In some implementations, reference Figures 2 to 4 As shown, to enable the second cover plate 300 to be movably connected to the first cover plate 200, allowing the second cover plate 300 to switch between a first state and a second state, the first cover plate 200 may include a first guide portion 220, and the second cover plate 300 may include a second guide portion 310. The first guide portion 220 and the second guide portion 310 are guided and engaged in opposite directions, allowing the second guide portion 310 to move relative to the first guide portion 220 along either the first or second direction. Both the first and second directions are opposite to each other. Figure 4 The X-axis direction is parallel.

[0071] When the second guide portion 310 moves along the first direction, the second cover plate 300 switches from the first state to the second state, causing the second cover plate 300 and the second access port 140 of the bottom shell 100 to gradually misalign until the second cover plate 300 and the second access port 140 of the bottom shell 100 are completely misaligned, thus fully opening the second access port 140. During this process, the first guide portion 220 always slides along the first direction, ensuring that the second cover plate 300 can always slide stably along the first direction, preventing the second cover plate 300 from tilting.

[0072] When the second guide portion 310 moves along the second direction, the second cover plate 300 switches from the second state to the first state, causing the second cover plate 300 to gradually face the second loading / unloading opening 140 of the bottom shell 100 until the second cover plate 300 and the second loading / unloading opening 140 of the bottom shell 100 are completely facing each other, thus completely closing the second loading / unloading opening 140. During this process, the second guide portion 310 always slides along the second direction, allowing the second cover plate 300 to slide stably along the second direction and preventing the second cover plate 300 from tilting.

[0073] Specifically, the first guide portion 220 can be a guide groove provided on the first cover plate 200, with one end of the guide groove extending to the surface of the first cover plate 200 to form an opening. The second guide portion 310 is a guide block provided on the surface of the second cover plate 300, with the guide block movably embedded in the guide groove, so that the guide block can move in the guide groove along a first direction and a second direction that are opposite to each other.

[0074] The second cover plate 300 is switched between the first state and the second state by moving the second cover plate 300. This makes the process of switching the second cover plate 300 between the first state and the second state simple and efficient. During this process, the first cover plate 200 does not move. The first cover plate 200 can always keep the first loading and unloading port 120 of the bottom shell 100 blocked, so as to avoid the metering component 400 being exposed.

[0075] In some implementations, reference Figures 4 to 7 As shown, the first cover plate 200 of this application may also be provided with a first snap-fit ​​portion 230, and the second cover plate 300 may also be provided with a second snap-fit ​​portion 320. When the second cover plate 300 is in the first state, the first snap-fit ​​portion 230 and the second snap-fit ​​portion 320 snap-fit ​​together, so that the second cover plate 300 and the first cover plate 200 can be further fixed together. Correspondingly, the second cover plate 300 can be relatively fixed to the bottom shell 100, so that the second cover plate 300 is stably connected to the first cover plate 200 when it is in the first state, and thus the second cover plate 300 can stably maintain the first state.

[0076] The first snap-fit ​​portion 230 can be disposed within the mounting cavity of the first cover plate 200, and the second snap-fit ​​portion 320 can be disposed on the side of the second cover plate 300 facing the mounting cavity. When the second cover plate 300 is in the first state, a portion of the second cover plate 300 is located within the mounting cavity, allowing the first snap-fit ​​portion 230 and the second snap-fit ​​portion 320 to engage.

[0077] Specifically, the first latching part 230 can be configured as a latching groove formed in the mounting cavity, and the second latching part 320 can be configured as a deformable buckle. The latching groove is oriented in the first direction. Correspondingly, when the battery 500 casing moves to the first state along the second direction, the buckle can move toward the latching groove. The buckle is deformed by the pressure of the inner wall of the latching groove, so that the buckle can be latched into the latching groove, thereby fixing the buckle in the latching groove.

[0078] When the second cover plate 300 moves to the second state along the first direction, the buckle can move away from the slot. The buckle is deformed by the inner wall of the slot, so that the buckle can be released from the slot.

[0079] Of course, in other embodiments, the first snap-fit ​​part 230 may also be a buckle provided in the mounting cavity, and the second snap-fit ​​part 320 may also be a slot provided on the surface of the second cover plate 300, so that the first snap-fit ​​part 230 and the second snap-fit ​​part 320 can also snap-fit ​​together.

[0080] In some implementations, reference Figure 8 As shown, to enable the first cover plate 200 to be movably connected to the second cover plate 300, the second cover plate 300 can switch between a first state and a second state. The first cover plate 200 and the second cover plate 300 can also be rotatably connected, allowing the second cover plate 300 to rotate relative to the first cover plate 200 to either the first state or the second state. The second cover plate 300 is configured to rotate relative to the bottom shell 100 along mutually opposing third or fourth directions, thereby allowing the second cover plate 300 to switch between the first state and the second state. When the second cover plate 300 rotates around the third or fourth direction, it rotates around... Figure 8 Rotation along the Y-axis.

[0081] For details, please refer to Figure 9 As shown, a pivot 340 can be provided on the edge of the second cover plate 300. The pivot 340 of the second cover plate 300 can be inserted through the first cover plate 200, so that the second cover plate 300 can rotate relative to the first cover plate 200.

[0082] When the second cover plate 300 rotates relative to the first cover plate 200 in a third direction, the second cover plate 300 can switch from the first state to the second state, causing the second cover plate 300 to be misaligned with the second access port 140 of the bottom shell 100. In this way, the second access port 140 is opened, and the battery 500 can be taken out or placed in the second cavity 130 of the bottom shell 100 through the second access port 140.

[0083] When the second cover plate 300 rotates relative to the first cover plate 200 in the fourth direction, the second cover plate 300 can switch from the second state to the first state, so that the second cover plate 300 is opposite to the second take-out port 140 of the bottom shell 100. In this way, the second take-out port 140 is closed and the battery 500 is sealed in the second cavity 130 of the bottom shell 100.

[0084] It should be understood that when the second cover plate 300 rotates in a third direction, the second cover plate 300 and the second access port 140 of the bottom shell 100 gradually misalign until the second cover plate 300 and the second access port 140 are completely misaligned, thus fully opening the second access port 140. When the second cover plate 300 rotates in a fourth direction, the second cover plate 300 and the second access port 140 of the bottom shell 100 gradually face each other until the second cover plate 300 and the second access port 140 of the bottom shell 100 are completely facing each other, thus sealing the second access port 140.

[0085] Since the second cover plate 300 is rotatably connected to the first cover plate 200, the second cover plate 300 and the first cover plate 200 are always connected when the second cover plate 300 switches between the first state and the second state. In this way, the second cover plate 300 will not separate from the first cover plate 200, avoiding the mutual disassembly and assembly of the second cover plate 300 and the first cover plate 200, and further improving the battery 500 replacement efficiency.

[0086] In some implementations, reference Figure 8 As shown, the first cover plate 200 of this application may include a first limiting part 240, and the second cover plate 300 may include a second limiting part 330. When the second cover plate 300 is in the first state, the first limiting part 240 and the second limiting part 330 cooperate to limit each other, so that the first limiting part 240 can limit the second limiting part 330 in the fourth direction. Correspondingly, it can limit the second cover plate 300, so that the second cover plate 300 cannot continue to rotate in the fourth direction, thus avoiding excessive rotation of the second cover plate 300 in the fourth direction.

[0087] Specifically, the first limiting part 240 can be a first limiting surface formed on the first cover plate 200, and the second limiting part 330 can be a second limiting surface on the second cover plate 300. When the second cover plate 300 is in the first state, the first limiting surface and the second limiting surface abut against each other, which can make the second cover plate 300 more stable in the first state.

[0088] In some implementations, reference Figure 1 As shown, in order to enable the battery 500 to be electrically connected to the metering component 400, the water meter controller of this application may also be provided with a connecting line 600, the two ends of the connecting line 600 being connected to the metering component 400 and the battery 500 respectively, so that the metering component 400 and the battery 500 are electrically connected, and the battery 500 can supply power to the metering component 400.

[0089] The bottom shell 100 may be provided with a wire harness groove 150, which is located between the first cavity 110 and the second cavity 130. Part of the connecting wire 600 can be snapped into the wire harness groove 150, which can fix the connecting wire 600, thereby making the connecting wire 600 more stably connected to the battery 500 and the metering component 400.

[0090] When replacing the battery 500, the connecting wire 600 can be separated from the battery 500. Due to the limiting effect of the wire harness slot 150, the other end of the connecting wire 600 can remain connected to the metering component 400 and be relatively fixed, which makes it easy to reconnect the new battery 500 to the connecting wire 600.

[0091] In some implementations, reference Figure 1 and Figure 8 As shown, the water meter controller of this application may also include multiple fasteners 700. A portion of the fasteners 700 are detachably inserted through the first cover plate 200 and the bottom shell 100 to fix the first cover plate 200 and the bottom shell 100. This makes the connection between the bottom shell 100 and the first cover plate 200 more stable, and when it is necessary to separate the first cover plate 200 from the bottom shell 100, some of the fasteners 700 can be disassembled.

[0092] Among the multiple fasteners 700, another number of fasteners 700 are detachably inserted through the second cover plate 300 and the bottom shell 100 to fix the second cover plate 300 and the bottom shell 100, so that when the second cover plate 300 is in the first state, the connection between the second cover plate 300 and the bottom shell 100 is stable.

[0093] Specifically, a fixing member 700 can be installed between the second cover plate 300 and the bottom shell 100. In this way, when it is necessary to switch the second cover plate 300 to the second state, only one fixing member 700 needs to be removed to allow the second cover plate 300 to move relative to the first cover plate 200, thereby improving the efficiency of the second cover plate 300 switching from the first state to the second state.

[0094] The fastener 700 is secured with bolts. Correspondingly, the first cover plate 200 and the bottom shell 100 have corresponding screw holes, and the second cover plate 300 and the bottom shell 100 also have corresponding screw holes. In addition, a lead seal 900 can be provided on the surface of the fastener 700. When the fastener 700 is disassembled, the lead seal 900 needs to be broken to determine whether the fastener 700 has been disassembled, and thus whether the metering component 400 in the first cavity 110 of the bottom shell 100 is exposed.

[0095] In some implementations, reference Figure 1 As shown, the water meter controller of this application may also include a protective shell 800, which may be disposed within the bottom shell 100 and the first cavity 110, and the protective shell 800 partially shields the metering component 400. Adhesive may be injected into the first cavity 110 to seal the metering component 400, thereby improving the waterproof performance of the water meter controller of this application.

[0096] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0097] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0098] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0099] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
