Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a water meter pre-filter. Background Technology

[0002] With the rapid development of IoT technology, NB-IoT (Narrowband Internet of Things) smart water meters are becoming increasingly common and an important component of modern urban water supply management. Smart water meters achieve accurate water measurement and real-time monitoring through remote data transmission, greatly improving the efficiency and accuracy of water resource management. However, water quality remains a key factor affecting the performance and lifespan of water meters.

[0003] Impurities and particulate matter in the water can not only clog the internal structure of the water meter, leading to inaccurate measurement, but also accelerate the aging and damage of the water meter. Therefore, installing a filter before the water meter to pre-treat the water entering the meter is a necessary measure to ensure the normal operation of the water meter and extend its service life.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integrally formed structures. Those skilled in the art can understand the specific meaning of these terms in this patent based on the specific circumstances.

[0022] like Figure 1 and Figure 2 As shown, the water meter pre-filter of this practical design includes a filter housing 1, which is divided into an upper inlet chamber and a lower outlet chamber. A filtration channel is reserved between the upper inlet chamber and the lower outlet chamber. A filter element 2 is installed in the filtration channel. The filter housing 1 is also equipped with an inlet pipe connector 3 connected to the upper inlet chamber and a drain pipe connector 4 connected to the lower outlet chamber.

[0023] The upper inlet chamber receives incoming water through inlet pipe connector 3, while the lower outlet chamber discharges filtered water through drain pipe connector 4. A filtration channel is provided between the two chambers, containing a filter element 2 to intercept and remove impurities and particulate matter from the water. When water flows into the upper inlet chamber through inlet pipe connector 3, it is filtered by the filter element 2, and the clean water flows into the lower outlet chamber, ultimately being discharged through drain pipe connector 4, thus achieving the purpose of pre-treating the water entering the water meter.

[0024] In one embodiment, the filter element 2 is a cylindrical filter element, and a hollow filter element placement cylinder 100 is provided in the filtration channel of the filter housing 1. A receiving seat 5 for abutting the water inlet of the filter element 2 is also provided in the lower outlet cavity of the filter housing 1. To achieve stable installation and positioning of the filter element, a hollow filter element placement cylinder 100 is specially provided in the filtration channel, providing a suitable installation environment for the filter element.

[0025] Specifically, the inlet of the filter element placement cylinder 100 is equipped with a hollow bracket 6, and a screw hole is pre-drilled in the center of the hollow bracket 6; a locking bolt 7 is installed inside the receiving seat 5, which passes through the filter element 2 and is threadedly connected to the screw hole of the hollow bracket 6. This bolt passes through the filter element 2 and is threadedly connected to the screw hole of the hollow bracket 6, thus achieving a stable installation of the filter element.

[0026] Specifically, the receiving seat 5 also has raised ribs 5.1 for positioning the inner ring of the filter element 2. This not only enhances the stability of the filter element but also ensures the accuracy of the filter element during installation, preventing it from shifting or loosening during use.

[0027] This embodiment achieves stable installation and precise positioning of the cylindrical filter element 2 within the filter housing 1 through the coordinated operation of components such as the filter element placement cylinder 100, the hollow bracket 6, the locking bolt 7, and the protruding rib 5.1 on the receiving seat 5, thereby ensuring the filtration effect and long-term use of the filter.

[0028] In one embodiment, the bottom of the filter housing 1 has a maintenance port facing the filter element 2, and a removable maintenance cover 8 is installed inside the maintenance port; the maintenance cover 8 is also equipped with a spring that abuts against the receiving seat 5 to improve compressive strength and stability. When the user needs to maintain the filter element, he / she can simply open the maintenance cover 8 to expose the filter element 2, thereby facilitating cleaning or replacement.

[0029] As one implementation, the filter housing 1 is also equipped with a pressure gauge 9 for detecting the water pressure in the upper inlet chamber, so that the user can intuitively understand the water pressure status at the filter inlet, thereby timely monitoring and judging the working status of the filter and the stability of the water supply system.

[0030] As one implementation, the filter housing 1 is also provided with a filter mounting bracket 10, which makes it convenient for users to install the filter securely on the wall, thereby saving space and ensuring the stable operation of the filter.

[0031] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise expressly specified and limited, the terms "installed," "connected," or "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection via an intermediate medium; or a connection within two elements. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0032] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
