[0001] The present application relates to the technical field of water meters, and in particular to a smart water meter. Background Art

[0002] A water meter is an instrument used to measure the total volume of water flowing through a tap water pipe. Currently, the counter in a water meter is connected to the base meter via a retaining ring. A cylindrical cover protects the counter housing, with a boss on the bottom that snaps into the meter case for secure attachment. However, due to prolonged exposure to moisture and water, the counter or movement may malfunction and require replacement. Due to structural limitations, the cover must be removed to remove the counter, resulting in increased costs for users. Utility Model Content

[0003] The purpose of the embodiments of the present application is to provide a smart water meter, in which the base and the box body can be disassembled without destroying them, thereby improving the convenience of assembly and disassembly, and at the same time improving the convenience of replacing the counter and the movement.

[0004] To achieve the above objectives, this application adopts the following technical solutions:

[0005] In one aspect, a smart water meter is provided, comprising:

[0006] A first housing is used to accommodate a water meter movement, wherein an annular groove is provided on an outer wall of the first housing;

[0007] a second housing for accommodating an electronic display counter, wherein the second housing is mounted on the first housing so that the water meter movement and the electronic display counter are electrically connected;

[0008] The base has a first boss convexly provided on its inner wall surface and engaged with the annular groove. The base is also provided with a break so that the base has an open state and a locked state. When in the open state, the first boss is disengaged from the annular groove. When in the locked state, the first boss is engaged with the annular groove.

[0009] The box body is detachably mounted on the base and covers the outer surface of the second shell.

[0010] Furthermore, a card slot is provided on the base, an opening is formed on one side of the card slot, and a first groove corresponding to the position of the card slot is provided at the bottom of the box body. The box body can be rotated in a first direction relative to the base so that one side portion of the first groove is inserted into the card slot from the opening.

[0011] Furthermore, the box body includes an upper box and a lower box, the lower box is provided with a second boss on a side opposite to the upper box, and the inner wall surface of the upper box is provided with a second groove that cooperates with the second boss.

[0012] Furthermore, the upper surface of the upper box is provided with a first installation position for installing the remote transmission module.

[0013] Furthermore, a cover is provided on the first installation position.

[0014] Furthermore, the upper surface of the upper box is also provided with a second installation position for installing a degree dial.

[0015] Furthermore, a folding cover is hinged on the side of the upper box, and the folding cover can be covered at the second installation position.

[0016] Furthermore, it also includes a pin shaft, a first hinge hole is provided on the side of the upper box, and a second hinge hole corresponding to the first hinge hole is provided on the folding cover. The pin shaft passes through the first hinge hole and the second hinge hole so that the folding cover is hinged to the upper box.

[0017] Furthermore, the lower box is provided with a wire hole for the wires to pass through.

[0018] Furthermore, it also includes a fastener, a first locking hole is provided at each diagonal position of the base, and a second locking hole corresponding to the first locking hole is provided on the box body, and the fastener passes through the first locking hole and the second locking hole to lock the box body to the base.

[0019] The beneficial effects of this application are as follows: the first housing is used to house the water meter movement, and its outer wall is provided with an annular groove to prepare for a stable connection with the base. The second housing is responsible for housing the electronic display counter and is installed with the first housing to ensure electrical connection between the movement and the counter, thereby accurately displaying water consumption. The design of the base is particularly critical. Its inner wall is provided with a first boss that matches the annular groove of the first housing. At the same time, the base is cleverly provided with a break, allowing the base to undergo elastic deformation and switch from a locked state to an open state, thereby allowing the base to be installed on the first housing. The base then returns to the locked state under the action of elastic force, and the first boss and the annular groove tightly cooperate to ensure the stability of the structure. The box body acts as a protective layer, which is detachably mounted on the base and covered on the outer surface of the second housing, providing additional protection for the counter. During the disassembly process, the user first removes the box body, then forcibly opens the base from the break, so that the base switches from the locked state to the open state again, thereby disengaging the first boss from the annular groove, and finally removes the base. At this time, the user can easily separate the connection between the first shell, the second shell and the base, and take out the internal movement or counter for replacement without destroying any parts, which greatly reduces the user's maintenance cost.

[0020] The design of this smart water meter not only improves the ease of assembly and disassembly, but also significantly enhances the convenience of replacing the counter and movement. At the same time, the robust structural design ensures the overall stability and durability of the smart water meter. Furthermore, since no components need to be damaged during disassembly, the smart water meter can be disassembled and reassembled multiple times, extending its service life and providing users with a more convenient and efficient water meter experience.

DETAILED DESCRIPTION

[0032] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0033] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0034] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0035] like Figures 1-9 As shown, this embodiment provides a smart water meter, including: a first shell 1, a second shell 2, a base 3 and a box body 4, the first shell 1 is used to accommodate the water meter movement, and the outer wall surface of the first shell 1 is provided with an annular groove 101; the second shell 2 is used to accommodate the electronic display counter, and the second shell 2 is installed on the first shell 1 so that the water meter movement and the electronic display counter are electrically connected; a first boss 302 is convexly provided on the inner wall surface of the base 3 and is connected to the annular groove 101, and a break 301 is also provided on the base 3 so that the base 3 has an open state and a locked state. When in the open state, the first boss 302 is disengaged from the annular groove 101, and when in the locked state, the first boss 302 is stuck in the annular groove 101; the box body 4 is detachably mounted on the base 3, and the cover is provided on the outer surface of the second shell 2.

[0036] Based on the above scheme, the smart water meter consists primarily of four components: a first housing 1, a second housing 2, a base 3, and a case 4. The first housing 1 houses the meter's movement, and its outer wall features a carefully designed annular groove 101, which is designed to form a secure mechanical connection with the first boss 302 of the base 3. The second housing 2 houses the electronic display counter and is tightly mounted to the first housing 1, ensuring accurate data transmission between the movement and the counter through electrical connection, thereby precisely displaying water consumption.

[0037] The design of the base 3 is the key to the entire smart water meter. Its inner wall features a first boss 302 that precisely matches the annular groove 101 of the first housing 1. This design ensures the stability of the two when connected. Even more ingenious, the base 3 is also provided with a break 301, which allows the base 3 to elastically deform, allowing it to easily switch from a locked state to an open state. During assembly, the user can place the base 3 on the first housing 1, and then the base 3 automatically returns to the locked state under the action of elastic force. At this point, the first boss 302 tightly fits the annular groove 101, ensuring the stability of the structure. The box body 4 acts as a protective layer, removably mounted on the base 3 and tightly covering the outer surface of the second housing 2, providing additional protection for the counter and preventing it from damage from the external environment. During disassembly, the user first removes the box body 4, then applies a certain amount of external force, utilizing the break 301 design of the base 3, to open the base 3 from the locked state to the open state. At this point, the connection between the first boss 302 and the annular groove 101 is released, allowing the user to easily remove the base 3 from the first housing 1. Subsequently, the user can conveniently separate the first housing 1, the second housing 2, and the base 3, and remove the internal movement or counter for replacement. This entire disassembly process does not require any damage to any components, significantly reducing maintenance costs for the user and improving the maintainability and service life of the smart water meter.

[0038] In some embodiments, the base 3 is provided with a slot 303, one side of which forms an opening 304. The bottom of the box body 4 is provided with a first groove 4021 corresponding to the position of the slot 303. The box body 4 can rotate relative to the base 3 in a first direction so that one side of the first groove 4021 snaps into the slot 303 through the opening 304. The carefully designed slot 303 on the base 3 has an opening 304 formed on one side. This opening 304 design makes it easier for the box body 4 to align with the slot 303 and snap into place during installation. At the same time, the bottom of the box body 4 is also provided with a first groove 4021 that matches the position of the slot 303. The design of this first groove 4021 not only matches the shape and size of the slot 303 but also ensures that the box body 4 fits tightly with the base 3 during installation and is not prone to loosening.

[0039] To install the box body 4, the user simply rotates the box body 4 relative to the base 3 in a first direction (typically clockwise or counterclockwise). As the box body 4 rotates, one side of the first groove 4021 gradually approaches and eventually engages with the slot 303 through the opening 304 of the slot 303. During this process, the connection between the box body 4 and the base 3 gradually becomes more secure until the first groove 4021 is fully engaged with the slot 303, at which point the connection between the box body 4 and the base 3 is optimal. This design not only simplifies the installation process but also improves installation accuracy and stability. Furthermore, due to the tight fit between the slot 303 and the first groove 4021, the box body 4 is unlikely to fall off or loosen after installation, thereby ensuring the safety and reliability of the counter during long-term use.

[0040] Furthermore, this rotational snap-in design makes disassembly much more convenient. When the user needs to disassemble the case 4, they simply rotate the case 4 in the opposite direction to disengage the first groove 4021 from the snap-in slot 303. This process does not require the use of any tools or excessive force, thus significantly reducing the difficulty and cost of disassembly.

[0041] In further optimization, the box body 4 of the smart water meter is designed as a split structure, including an upper box 401 and a lower box 402. This design not only improves the overall stability of the box body 4, but also makes the installation and disassembly process more flexible and convenient. Specifically, a second boss 4022 is designed on the opposite side of the lower box 402 (i.e., the side combined with the upper box 401). This second boss 4022 has a specific shape and size, and is intended to fit tightly with the second groove 4014 provided on the inner wall of the upper box 401. When the upper and lower boxes 402 are combined, the second boss 4022 will be accurately inserted into the second groove 4014, thereby achieving a stable connection between the two. This mating connection design not only enhances the overall structural strength of the box body 4, but also ensures that the upper and lower boxes 402 are not easy to loosen or fall off after installation. At the same time, due to the close fit between the second boss 4022 and the second groove 4014, the space inside the box body 4 is also better sealed and protected, thereby effectively preventing the influence of external factors such as dust and moisture on the counter.

[0042] Furthermore, a first mounting position 4011 for mounting a remote transmission module has been added to the upper surface of the upper box 401. This design enables the water meter to have remote communication capabilities, thereby realizing remote transmission and monitoring of data. The first mounting position 4011 is designed on the upper surface of the upper box 401, and its shape and size match the remote transmission module to ensure that the remote transmission module can be securely installed in this position. The remote transmission module typically includes key components such as a communication module and a data processing module, which are used to realize the remote collection, transmission, and processing of water meter data. To protect the remote transmission module from interference and damage from the external environment, a cover 5 is also provided on the first mounting position 4011. This cover 5 is made of waterproof material and has excellent sealing properties. It can effectively prevent external factors such as dust and moisture from invading the interior of the first mounting position 4011, thereby ensuring the normal operation and long-term stability of the remote transmission module.

[0043] The design of cover 5 also takes installation convenience into consideration. Users can open or close cover 5 with simple operations (such as rotating or snapping), making it easy to install or remove the remote transmission module. This design not only improves installation efficiency but also reduces maintenance costs.

[0044] In addition, the upper surface of the upper box 401 is provided with a second mounting position 4012 for mounting the dial 7. A foldable cover 6 is hingedly attached to the side of the upper box 401, which can be placed over the second mounting position 4012. The upper surface of the upper box 401 not only features the first mounting position 4011 for mounting the remote transmission module, but also includes a second mounting position 4012 for mounting the dial 7. This design allows the water meter to display both the traditional dial 7 reading and the remotely transmitted digital reading, providing users with a more comprehensive and intuitive understanding of water usage. Specifically, the second mounting position 4012 is cleverly designed on the upper surface of the upper box 401, its shape and size matching the dial 7 to ensure that it can be securely installed in this position. The dial 7 includes key elements such as a pointer and scale, which provide a visual display of the water meter reading. To protect the dial 7 from external interference and damage and to enhance user convenience in viewing the reading, a foldable cover 6 is hingedly attached to the side of the upper box 401. The design of the folding cover 6 not only takes into account the functionality of protecting the dial 7 but also takes into account ease of use. With a simple folding operation, the user can open or close the cover, conveniently viewing or protecting the dial 7. When the user needs to check the water meter reading, the user simply opens the folding cover 6 to clearly see the reading on the dial 7. When not needed, the user can close the folding cover 6 to protect the dial 7 from external damage.

[0045] To achieve a secure and flexible hinged connection between the folding cover 6 and the upper case 401, a key component, the hinge pin 8, is incorporated. The following is a detailed description of this design: First, a first hinge hole 4013 is designed on the side of the upper case 401. This hole is not only precisely positioned but also precisely dimensioned to ensure a smooth and secure insertion of the hinge pin 8. Furthermore, the shape and depth of the first hinge hole 4013 are optimized to provide sufficient support and stability, preventing the hinge pin 8 from loosening or falling off during use. Second, a second hinge hole 601 is also provided on the folding cover 6, corresponding to the first hinge hole 4013. The alignment and fit of these two holes are crucial to ensuring a smooth hinged connection between the folding cover 6 and the upper case 401. The shape, size, and location of the second hinge hole 601 match those of the first hinge hole 4013, ensuring that the hinge pin 8 can pass through both holes simultaneously, thus achieving a secure connection between the folding cover 6 and the upper case 401. Finally, the pin 8, a key component connecting the folding cover 6 and the upper box 401, has been meticulously designed in terms of material, size, and shape. Pin 8 is typically made of high-strength, corrosion-resistant materials to ensure sufficient strength and stability during use. Furthermore, the diameter and length of pin 8 are precisely calculated to ensure it fits snugly through the first hinge hole 4013 and the second hinge hole 601, while providing sufficient rotational flexibility.

[0046] During assembly, the user simply aligns the second hinge hole 601 of the folding cover 6 with the first hinge hole 4013 of the upper case 401 and then passes the pin 8 through both holes. This process requires no tools or excessive force, significantly reducing assembly difficulty and cost. Furthermore, thanks to the tight fit and flexible rotation of the pin 8, the folding cover 6 can be easily switched between open and closed positions, providing a more convenient and comfortable user experience.

[0047] Generally speaking, the lower box 402 defines a cable hole 4023 for routing cables. The location, shape, and size of the cable hole 4023 are carefully designed based on factors such as the type, number, and diameter of the cables. The cable hole 4023 is typically positioned appropriately within the lower box 402 to ensure smooth routing of the cables without obstruction or damage. Furthermore, the shape and size of the cable hole 4023 are optimized to provide ample space for the cables and to ensure they are not excessively squeezed or bent during routing.

[0048] Optionally, fasteners 9 are further included. A first locking hole 305 is provided at a diagonal position on the base 3, and a second locking hole 403 corresponding to the first locking hole 305 is provided on the box body 4. The fasteners 9 pass through the first and second locking holes 305, 403 to lock the box body 4 to the base 3. By providing corresponding first and second locking holes 305, 403 on the base 3 and box body 4, respectively, and using the fasteners 9 to lock the box body 4 to the base 3 through these two holes, the design of this smart water meter not only improves the connection stability between the box body 4 and the base 3, but also reduces the difficulty and cost of assembly. This design further enhances the overall structural strength and operational reliability of the smart water meter, providing users with a safer, more stable, and more efficient water meter experience.
