Technical Field
[0001] This utility model relates to water meters, and more specifically, to a single-jet water meter. Background Technology
[0002] As a crucial water consumption measuring instrument, the accuracy, measurement range, reliability, lifespan, functionality, and manufacturing cost of water meters all affect water metering, water billing, and their value in water control, conservation, and management. Single-jet water meters typically offer high accuracy, accurately measuring water flow. Their relatively simple structure and cost-effectiveness are also advantageous. Furthermore, single-jet water meters exhibit low pressure loss, enabling long-term use under various environmental conditions.

Detailed Implementation
[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0027] like Figures 1 to 2As shown, a single-jet water meter includes a water meter housing 1, a water meter cover 2 covering the surface of the water meter housing 1, a retaining ring 3 on the inner wall of the water meter housing 1, a base 4 movably connected to the retaining ring 3, a circuit board assembly 5 on the inner wall of the base 4, a sealing ring 6 sleeved on the outer periphery of the base 4, the sealing ring 6 sealingly connected to the water meter cover 2, the sealing ring 6 being disposed on the surface of the water meter housing 1, and an inlet and an outlet opening on the periphery of the water meter housing 1, with an inlet pipe 7 and an outlet pipe 8 respectively provided on the inlet and outlet.
[0028] The inlet pipe 7 and outlet pipe 8 extend to the outside of the water meter housing 1, and their ends are provided with threaded connection structures for connecting to external pipes. The water meter housing 1 provides support for the water meter cover 2, which can protect the corresponding components, reduce dust entry, improve overall durability, and keep the tap water entering the water meter clean. The retaining ring 3 provides support for the retaining seat, and the movable connection between them facilitates component replacement. The circuit board assembly 5 is a PCBA, which is short for Printed Circuit Board Assembly 5 manufacturing process. It refers to the process of assembling components on a blank PCB board using surface mount technology or dual in-line package technology. The PCBA comes with a battery, and the sealing ring 6 can maintain good sealing between the base 4 and the water meter cover 2.
[0029] like Figures 2 to 3 As shown, the inner wall of the retaining ring 3 is fixedly connected with several first retaining plates 9, and the base 4 is fixedly connected with several second retaining plates 10. The first retaining plates 9 and the second retaining plates 10 are staggered. The inner wall of the retaining ring 3 is also provided with a fixing plate 11 for abutting against the second retaining plates 10. The fixing plate 11 is located at the bottom of the first retaining plates 9. The fixing plate 11 provides good support for the base 4. Through the staggered intersection and snapping between the first retaining ring 3 and the second retaining ring 3, a good positioning effect is achieved, which facilitates the installation of the base 4 and prevents misinstallation.
[0030] like Figure 4 As shown, an inlet stop ring 12 is provided on the inlet pipe 7. Several inlet stops 13 are provided on the inlet stop ring 12. Each inlet stop 13 is provided with an inlet column 14. The inlet column 14 is elastically connected to an inlet spring 15. The inlet spring 15 is fixedly connected to an inlet support plate 16. The inlet support plate 16 is fixedly connected to one side of the inlet stop ring 12.
[0031] Tap water can enter the inlet pipe 7 through the inlet stop 13 on the inlet stop ring 12. When there is no tap water flowing in the pipe, the inlet spring 15 releases its elastic force, causing the inlet column 14 to start moving and blocking the inlet stop 13 of the inlet stop ring 12. When tap water flows, the pressure of the tap water causes the inlet column 14 to move, the inlet stop 13 is opened, the inlet spring 15 is compressed, and the tap water enters the inlet pipe 7.
[0032] like Figure 5 As shown, a water outlet stop ring 17 is provided on the inner wall of the water outlet pipe 8 facing the water inlet pipe 7. Several water outlet stops 18 are provided on the water outlet stop ring 17, and a water outlet column 19 is provided on each water outlet stop 18. A water outlet spring 20 is elastically connected to the water outlet column 19. The water outlet spring 20 is fixedly connected to a water outlet support plate 21. The water outlet support plate 21 is fixedly connected to one side of the water outlet stop ring 17.
[0033] Tap water can enter the outlet pipe 8 through the outlet stop 18 of the outlet stop ring 17. When there is no tap water flowing in the pipe, the outlet spring 20 releases its elastic force, causing the outlet column 19 to start moving and blocking the outlet stop 18 of the outlet stop ring 17. When tap water flows, the pressure of the tap water causes the outlet column 19 to start moving, the outlet stop 18 is opened, the outlet spring 20 is compressed, and the tap water enters the outlet pipe 8.
[0034] like Figure 2 and Figure 6 As shown, a water filter port 22 is provided at the bottom of the water meter housing 1. A water filter column 23 is provided on the water filter port 22. A water filter spring 24 is elastically connected to the water filter column 23. A water filter support plate 25 is fixedly connected to the water filter spring 24. The water filter support plate 25 is fixedly connected to the bottom of the water meter housing 1.
[0035] When the tap water in the pipeline begins to flow, the tap water enters the water meter housing 1 through the inlet pipe 7, and the water pressure opens the filter port 22, causing the filter column 23 to be displaced and the filter spring 24 to be compressed. It can be opened for sampling or pressure relief when needed.
[0036] like Figure 2 and Figure 6 As shown, a water filter box 26 is provided at the bottom of the water meter housing 1; the water filter box 26 can store the tap water flowing out of the water meter housing 1.
[0037] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
