[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a water inlet connection device for a water heater, including a connecting pipe 1. One end of the connecting pipe 1 is welded to a flange 2. A flow meter 3 is connected to one side of the flange 2 by a sealing bolt. A filter pipe 4 is connected to the middle of the connecting pipe 1. A sealing cap 5 is threaded to the bottom of the filter pipe 4. A set of concave grooves 6 are opened on the inner sidewalls of the connecting pipe 1 and the filter pipe 4. A filter plate 7 for filtering water flow is movably inserted inside the concave groove 6. A set of threaded interfaces 8 are connected to the water inlet end of the connecting pipe 1 and the drain end of the flow meter 3.

[0023] In use, the connecting pipe 1 and the flow meter 3 are connected by a flange 2. The threaded interface 8 at the inlet of the connecting pipe 1 is used to connect to the main water supply pipe, and the threaded interface 8 at the drain of the flow meter 3 is used to connect to the inlet of the water heater, thus achieving the connection between the water heater and the main water supply pipe. Through the filter pipe 4 installed at the bottom of the connecting pipe 1, and utilizing the concave groove 6 opened on the inner side wall of the connecting pipe 1 and the filter pipe 4, the filter plate 7 is inserted into the concave groove 6, thereby achieving the effect of filtering the water flow and preventing large particles of impurities from passing through. In the event of pipe blockage or equipment damage inside the water heater, the filter pipe 4 is sealed by the sealing cover 5, which also limits the installation of the filter plate 7. When the filter plate 7 needs cleaning, simply open the sealing cover 5 and clean it directly. This allows for quick installation and removal of the filter plate 7. The main pipeline does not need to be disassembled when cleaning the filter plate 7. Furthermore, the filtration area of ​​the filter plate 7 is larger than the cross-sectional area of ​​the inner diameter of the connecting pipe 1, preventing a sudden drop in water flow due to the filter plate 7. At the same time, the filtered impurities are collected on the inside of the filter pipe 4 for easy cleaning.

[0024] The filter plate 7 includes a sealing plate 71. The outer side of the sealing plate 71 is movably fitted to the inner wall of the filter pipe 4. By setting the sealing plate 71, the impact of water on the sealing cover 5 can be reduced, and the leakage caused by the sealing cover 5 not being properly sealed due to water flow impact can be reduced. At the same time, the sealing plate 71 plays a certain supporting and limiting role. The top of the sealing plate 71 is fitted to the inside of the sealing cover 5 to prevent the filter plate 7 from moving downward and causing gaps between the filter plate 7 and the inner wall of the connecting pipe 1, thus forming a filtration blind zone.

[0025] The top of the sealing plate 71 is equipped with a fixing frame 72 that is inserted into the concave groove 6. A filter screen 73 is installed on the inner side of the fixing frame 72. The fixing frame 72 provides support and fixation for the filter, and the filter screen 73 filters the water.

[0026] The inlet end of the flow meter 3 is provided with a docking groove 9, and a sealing ring 10 is installed inside the docking groove 9. Through the connection relationship between the flow meter 3, the docking groove 9, the sealing ring 10, and the flange 2, the sealing performance when the flow meter 3 is connected to the flange 2 is increased, and leakage is avoided when the connecting pipe 1 is connected to the flow meter 3.

[0027] The outer arc surface of the connecting pipe 1 is provided with an installation groove 11. A fixing plate 12 is bolted inside the installation groove 11. A temperature sensor 13 is installed through the middle of the fixing plate 12. One end of the temperature sensor 13 extends into the interior of the connecting pipe 1. Through the connection relationship between the connecting pipe 1, the installation groove 11, the fixing plate 12, and the temperature sensor 13, the thermometer is bolted to the interior of the installation groove 11 through the fixing plate 12, and one end of the temperature sensor 13 is inserted into the interior of the connecting pipe 1, so as to achieve the effect of quick installation and removal of the temperature sensor 13, which is convenient for maintenance or replacement of the temperature sensor 13. The temperature sensor 13 is used to monitor the water temperature.

[0028] The flow meter 3 has a connection port 14 on its top. The connection port 14 and the temperature sensor 13 are electrically connected to the water heater's control system via a data cable. The flow meter 3 is electrically connected to the water heater's control system via the line connected to the connection port 14. The flow meter 3 detects the water flow velocity and flow signal and transmits it to the water heater's control system. After processing, the control system adjusts the heating power of the water heater to match the water flow requirements, avoiding excessive energy consumption due to excessive power or insufficient water heating temperature due to insufficient power. Similarly, the temperature sensor 13 transmits the original water temperature signal to the water heater, which then performs corresponding heating treatments to improve heating efficiency, reduce losses, and save costs.

[0029] Fixing lugs 15 are symmetrically installed on the outer side of the connecting pipe 1. The fixing lugs 15 have mounting holes in the middle for bolting and fixing. The entire connecting device is fixed in the designated position by the fixing lugs 15 installed on both sides of the connecting pipe 1 and the positioning screws installed in the mounting holes, so as to achieve the effect of fixed installation of the connecting device. It is worth noting that space should be reserved for the disassembly of the sealing cover 5 and the filter plate 7. The filter plate 7 can be fixed by pre-embedding the crossbeam, so that the filter pipe 4 is in a suspended state, which makes it convenient to replace the filter plate 7.

[0030] In practical use, the connecting device is fixedly installed in the designated position using the fixing ear 15. The water supply pipe is sealed and connected to the threaded interface 8 of the water inlet. Then, one end of the water inlet pipe of the hot water heater is sealed and connected to the threaded interface 8 of the water outlet, thereby achieving the effect of connecting the water inlet of the water heater to the water supply pipe. Through the filter pipe 4 set at the bottom of the connecting pipe 1, and using the concave groove 6 opened on the inner side wall of the connecting pipe 1 and the filter pipe 4, the filter plate 7 is inserted into the concave groove 6, thereby achieving the effect of filtering the water flow and preventing large particles of impurities from entering the water heater and causing pipe blockage or equipment damage. When it is necessary to clean the filter screen 73, the water valve is turned off to stop the water supply, the sealing cover 5 is opened, the filter plate 7 is pulled out from the concave groove 6, the filter plate 7 is cleaned of impurities, and then put back and the sealing cover 5 is closed, thereby achieving the effect of quickly cleaning the filter screen 73.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
