For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0039] According to an embodiment of the utility model, a water meter structure is provided, comprising:

[0040] A first shell 101 has a cavity 3 inside, and an opening exposing the cavity 3 is formed on one end surface of the first shell 101;

[0041] The partition plate 2 is disposed in the cavity 3 to separate the cavity 3 into a first cavity 301 and a second cavity 302;

[0042] The antenna 4 is disposed in the first cavity 301 . The size of the first cavity 301 is adapted to the size of the antenna 4 , so that the first cavity 301 is suitable for accommodating the antenna 4 .

[0043] The water meter structure provided in this embodiment divides the cavity 3 into a first cavity 301 and a second cavity 302 by arranging a partition 2 inside the cavity 3, and makes the size of the first cavity 301 match the size of the antenna 4 so as to facilitate the placement of the antenna 4 in the first cavity 301.

[0044] Specifically, the antenna 4 includes a sheet metal antenna, a spring antenna, a PCB antenna (printed circuit board antenna), and an FPC antenna (flexible printed circuit antenna). Taking the sheet metal antenna as an example, compared with other types of antennas, the sheet metal antenna has a longer service life and better use effect. Therefore, applying the sheet metal antenna to the water meter is conducive to improving the service life and use effect of the water meter. However, the size of the sheet metal antenna is larger than that of other types of antennas, and the structure of the water meter used to place other antennas in the related art cannot be directly adapted to the sheet metal antenna.

[0045] Preferably, the plane where the partition 2 is located is perpendicular to the plane where the opening is located, and the height of the partition 2 is adapted to the depth of the cavity 3, the depth of the first cavity 301 is adapted to the height of the antenna 4, and the cross-sectional dimensions of the first cavity 301 are adapted to the cross-sectional dimensions of the antenna 4 along the direction perpendicular to the depth of the first cavity 301, so that the antenna 4 can be slidably placed in the first cavity 301 through the opening corresponding to the first cavity 301, and the second cavity 302 is suitable for placing the following circuit board 7, battery 8 and other components in the water meter. The first cavity 301 is an independent space for placing the antenna 4, and when other components of the water meter are replaced, the antenna 4 will not be affected.

[0046] In some embodiments, in combination Figures 1 to 7 As shown, a flange 5 is provided at the opening of the first cavity 301 , and the water meter structure further includes a cover plate 6 , which has a groove 601 formed thereon corresponding to the flange. The cover plate 6 is buckled onto the flange 5 through the groove 601 to cover the opening of the first cavity 301 .

[0047] The water meter structure provided in this embodiment is tightly matched with the flange 5 through the groove 601, so that the cover plate 6 is buckled on the flange 5, thereby covering the opening of the first cavity 301, thereby making the first cavity 301 an independent space.

[0048] Specifically, at least a part of the flange 5 is suitable for extending into the groove 601, and the outer wall of the flange 5 is interference-fitted with the inner wall of the groove 601, so that the cover plate 6 is buckled on the flange 5 through the interference fit between the flange 5 and the groove 601, and covers the opening corresponding to the first cavity 301, thereby preventing water from entering the first cavity 301, and forming an independent space for the first cavity 301. Preferably, the flange 5 is arranged around the opening corresponding to the first cavity 301, and the area of ​​the partition 2 close to the above opening is constructed as a part of the flange 5, which is conducive to improving the protective effect of the cover plate 6 on the antenna 4 inside the first cavity 301.

[0049] In some embodiments, in combination Figures 1 to 7As shown, the second cavity 302 includes a box-shaped space and a cylindrical space that are connected to each other. The box-shaped space is arranged corresponding to the first cavity 301. The water meter structure also includes a circuit board 7, and the circuit board 7 is arranged in the box-shaped space.

[0050] Specifically, sealant is poured into the area where the circuit board 7 is located to form a third sealant that wraps the circuit board 7, thereby achieving a waterproof effect for the circuit board 7. Since the antenna 4 cannot be sealed, the antenna 4 is placed in an independent space formed by the first cavity 301 and the cover plate 6, so that the antenna 4 can be waterproof without the need for sealing, which is conducive to ensuring the performance and service life of the antenna 4.

[0051] In some embodiments, in combination Figures 1 to 7 As shown, a through hole 201 connecting the first cavity 301 and the box-shaped space is formed on the partition plate 2 , and a pin 401 of the antenna 4 extends through the through hole 201 into the box-shaped space so as to be suitable for connection with the circuit board 7 .

[0052] The water meter structure provided in this embodiment has a through hole 201 formed on the partition 2 to make way for the pin 401 , so as to facilitate the connection of the antenna 4 with the circuit board 7 through the pin 401 .

[0053] Specifically, one end of the pin 401 is connected to the antenna 4, and the other end passes through the through hole 201 to connect to the circuit board 7. Since part of the pin 401 is inserted into the through hole 201, the through hole 201 can also limit the pin 401, thereby improving the installation stability of the antenna 4.

[0054] The second cavity 302 includes a box-shaped space and a cylindrical space connected to each other. The box-shaped space is arranged corresponding to the first cavity 301 and is connected to the first cavity 301 through the through hole 201. The circuit board 7 is arranged in the box-shaped space so that the pin 401 passes through the through hole 201 and connects the circuit board 7 and the antenna 4. The cylindrical space of the second cavity 302 is suitable for accommodating the battery 8. Figure 3 , Figure 4 and Figure 6 As shown, two relatively arranged slot structures 10 are fixedly connected to the side walls of the box-shaped space, and a groove extending in a direction perpendicular to the plane where the opening is located is opened on the slot structure 10. The circuit board 7 is suitable for being inserted into the grooves of the two slot structures 10 through the opening corresponding to the second cavity 302, so as to facilitate the installation of the circuit board 7 in the second cavity 302. After the installation is in place, sealant is poured into the box-shaped space where the slot structure 10 is located to form a third sealing colloid that wraps the circuit board 7, thereby realizing waterproof treatment of the circuit board 7.

[0055] In some embodiments, in combination Figures 1 to 7As shown, the gap between the pin 401 and the inner wall of the through hole 201 is filled with a first sealing colloid.

[0056] The water meter structure provided in this embodiment fills the gap between the pin 401 and the inner wall of the through hole 201 with a first sealing colloid to prevent moisture in the second cavity 302 from entering the first cavity 301 through the through hole 201, thereby affecting the performance and life of the antenna 4.

[0057] Specifically, by filling the gap between the pin 401 and the inner wall of the through hole 201 with the first sealing colloid, it is possible to prevent part of the sealing colloid from entering the first cavity 301 through the through hole 201 when the circuit board 7 is being filled with glue, which is beneficial to improving the protection effect of the antenna 4.

[0058] In some embodiments, in combination Figures 1 to 7 As shown, a local area of ​​the end surface of the partition 2 facing the opening is recessed to form a groove, and the groove is connected to the through hole 201, so that the pin 401 falls into the through hole 201 through the groove.

[0059] The water meter structure provided in this embodiment forms a groove connected to the through hole 201 on the partition 2, so that the pin 401 can be slidably placed in the through hole 201 through the groove, which is beneficial to improving the convenience of operation.

[0060] Specifically, the axis of the through hole 201 is perpendicular to the plane where the partition 2 is located, and the groove penetrates the partition 2 along the axis direction of the through hole 201. When the antenna 4 is placed into the first cavity 301 through the opening, the pin 401 connected to the antenna 4 falls into the through hole 201 through the groove, which is beneficial to improve the operational convenience when installing the antenna 4.

[0061] In some embodiments, in combination Figures 1 to 7 As shown, a local area of ​​the inner wall of the first shell 101 corresponding to the first cavity 301 is recessed to form a preset groove 9, and the preset groove 9 has a connected state in which its bottom wall is destroyed to connect the inside and outside of the first shell 101; when the preset groove 9 is in the connected state, the water meter structure also includes an external antenna, one end of the external antenna is located inside the first shell 101, and the other end extends to the outside of the first shell 101 through the preset groove 9.

[0062] The water meter structure provided in this embodiment is provided with a preset groove 9 on the inner wall of the first shell 101, so that when an external antenna needs to be set, the bottom wall of the preset groove 9 is destroyed, so that the preset groove 9 passes through the first shell 101, and the external antenna passes through the preset groove 9 to the outside of the first shell 101, which is beneficial to improving the applicability and operational convenience of the water meter structure.

[0063] Specifically, the preset groove 9 is formed by a local area of ​​the inner wall of the first shell 101 being recessed, so the wall thickness of the first shell 101 at the preset groove 9 is less than the wall thickness of other areas. When it is necessary to set an external antenna, a force is applied to the area of ​​the first shell 101 corresponding to the preset groove 9 to destroy the bottom wall of the preset groove 9, so that the preset groove 9 connects the inside and outside of the first shell 101, wherein the bottom wall of the preset groove 9 cannot be restored once it is destroyed. The external antenna is a linear antenna connected to the circuit board 7, and a corrugated tube is to be sleeved on the outer peripheral side of the linear antenna, which requires a certain reserved space, so the preset groove 9 is set on the inner wall of the first cavity 301. The end of the external antenna away from the circuit board 7 passes through the through hole 201 to enter the first cavity 301, and continues to pass through the preset groove 9 in a connected state, thereby extending to the outside of the first shell 101, at which time the first sealing colloid is suitable for blocking the pin 401 and the gap between the external antenna and the inner wall of the through hole 201. When there is no need to set up an external antenna, the bottom wall of the preset groove 9 is not destroyed to ensure the airtightness of the first cavity 301. When an external antenna is needed, it is only necessary to destroy the bottom wall of the preset groove 9 to achieve the internal and external connection of the first shell 101, so that the external antenna can pass through the first shell 101, thereby improving the applicability of the water meter structure and the convenience of operation.

[0064] In some embodiments, in combination Figures 1 to 7 As shown, when the preset groove 9 is in a connected state, the second sealing colloid is filled between the external antenna and the inner wall of the preset groove 9 .

[0065] The water meter structure provided in this embodiment fills the second sealing colloid in the gap between the inner wall of the preset groove 9 and the external antenna to ensure the waterproofness of the first cavity 301, which is beneficial to protecting the antenna.

[0066] Specifically, when the bottom wall of the preset groove 9 is destroyed to connect the inside and outside of the first shell 101, and an external antenna is inserted into the preset groove 9, sealant is filled into the gap between the external antenna and the inner wall of the preset groove 9 to form a second sealing colloid, thereby ensuring the sealing effect of the first cavity 301, which is beneficial to ensuring the protection effect of the antenna 4.

[0067] In some embodiments, in combination Figures 1 to 7 As shown, the water meter structure also includes a battery 8 , which is located in the cylindrical space and electrically connected to the circuit board 7 .

[0068] Specifically, the battery 8 is suitable for providing power to the circuit board 7. Since the battery 8 needs to be replaced frequently, the antenna 4 that cannot be sealed with glue is arranged inside an independent first cavity 301. Therefore, when the battery 8 or other components of the water meter structure are replaced, the waterproof measures of the antenna 4 will not be affected, which is conducive to ensuring the service life and use effect of the antenna 4.

[0069] In some embodiments, in combination Figures 1 to 7 As shown, the water meter structure further includes a second shell 102 , which is fixedly connected to the first shell 101 to cover the opening of the cavity 3 .

[0070] Specifically, the second shell 102 is arranged on the opening side of the first shell 101, and is detachably connected to the first shell 101, so as to facilitate the disassembly and assembly of the components inside the water meter structure. The first shell 101 and the second shell 102 are snap-fitted and connected to form the shell 1 of the water meter structure. The first shell 101 and the second shell 102 can be detachably connected in the form of a snap connection, or threaded holes can be opened at corresponding positions of the first shell 101 and the second shell 102 to facilitate detachable connection by fastening screws. When the second shell 102 is in a connected state with the first shell 101, the second shell 102 is suitable for covering the opening of the first shell 101 to protect the components inside the first shell 101. As a feasible implementation form, the first shell 101 is constructed as a lower shell, and the second shell 102 is constructed as an upper shell. An opening exposing the cavity 3 is formed on the upper end surface of the lower shell, and the partition 2 is arranged in the vertical direction, so that the first cavity 301 is formed as a vertical space, which is suitable for the case where the antenna 4 is installed vertically.

[0071] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. Although the embodiments of the present utility model are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present utility model, and such modifications and variations are all within the scope defined by the present utility model.
