[0002] At present, water flow sensors are arranged at the joints of gas water heaters. For the existing water flow sensors, generally, the inner cavity of a rotor assembly made of a magnet is arranged in the joint channel, and a Hall sensor is arranged outside the corresponding rotor assembly to judge the rotation speed of the rotor assembly, and further judge the flow rate of the water flow. For example, a built-in water flow sensor joint and a gas instantaneous water heater disclosed in the patent number CN201820849296.8.

[0003] However, this kind of water flow sensor has a single function; and since the rotor assembly is built in the joint channel, under the continuous water flow transmission, the rotor assembly is prone to wear or fouling, which affects the detection stability of the water flow sensor. At this time, to repair and replace the rotor assembly, the entire water flow sensor needs to be removed from the pipeline, and the repair is cumbersome and difficult. Therefore, further improvement is needed. Summary of the Utility Model

[0028] Embodiment

[0029] Referring to Figures 1 to 3 , a water flow sensing device with multiple functions, easy to disassemble and assemble for maintenance, proposed by the present utility model, includes: a connector pipe 10, a rotor assembly 20, and a temperature measurement module 30;

[0030] The connection pipe 10 is provided with a water flow channel 11 that runs through from front to back; a rotor connection port 12 is provided on the side of the connection pipe 10, and the rotor connection port 12 communicates with the water flow channel 11; the temperature measurement module 30 is detachably installed on the connection pipe 10 and extends into the water flow channel 11.

[0031] The rotor assembly 20 includes a rotor connection seat 21, a magnetic rotor 22 and a Hall sensor provided on the rotor connection seat 21; the rotor connection seat 21 is detachably installed on the rotor connection port 12, and the magnetic rotor 22 extends into the water flow channel 11.

[0032] In the present utility model, the rotor assembly 20 includes a rotor connection seat 21, a magnetic rotor 22 and a Hall sensor provided on the rotor connection seat 21; during the reinstallation process, the rotor connection seat 21 is detachably installed on one side of the rotor connection port 12, so that the magnetic rotor 22 and the Hall sensor can be synchronously disassembled and assembled from the side; when maintenance is required, it is not necessary to remove the flow sensor as a whole, and only the rotor connection seat 21 needs to be removed from one side, and the maintenance of the water flow sensor is simple and convenient; moreover, the temperature measurement module 30 provided on the water flow sensor can detect the water temperature of the water in the water flow channel 11, realizing the multi-functional integration of water flow detection and water flow temperature measurement.

[0033] The Hall sensor can be embedded in or bolt-mounted on the rotor connection seat 21, and the Hall sensor is not drawn in the figure.

[0034] In this embodiment, rotor limit through holes 13 are provided on the opposite sides of the cross section of the rotor connection port 12, and rotor limit grooves 211 are provided on the outer periphery of the opposite sides of the rotor connection seat 21; the U-shaped limit lock 23 can be inserted through the rotor limit through holes 13 and clamped in the rotor limit grooves 211 on both sides of the rotor connection seat 21. By using the U-shaped limit lock 23, the position of the rotor connection seat 21 can be conveniently locked and restricted, preventing the rotor connection seat 21 from detaching from the connection pipe 10.

[0035] Specifically, the U-shaped limit lock 23 includes a horizontal connection section 231 and two vertical limit sections 232; the two vertical limit sections 232 are bent and formed on both sides of the horizontal connection section 231. A metal strip can be bent to form the horizontal connection section 231 and the vertical limit sections 232 on both sides, thereby forming a "U"-shaped limit lock for limit fixation.

[0036] Furthermore, a limit hook 14 is provided on one side of the rotor connection port 12, and the horizontal connection section 231 can be snapped into the limit hook 14. The limit hook 14 has a columnar structure with an opening on one side. When installing the U-shaped limit lock 23, it can be deformed towards one side to make the horizontal connection section 231 slide in and abut and engage with the horizontal connection section 231.

[0037] In this embodiment, the rotor connection port 12 is provided with a positioning notch 15; the rotor connection seat 21 is provided with a positioning protrusion 212; the positioning protrusion 212 can be embedded in the positioning notch 15. The positioning protrusion 212 is aligned with the positioning notch 15, which can limit the relative position between the rotor connection seat 21 and the rotor connection port 12, so as to facilitate the U-shaped limit latch 23 to align with the rotor limit groove 211.

[0038] Specifically, there are two positioning notches 15, located on the opposite sides of the rotor connection port 12; correspondingly, there are two positioning protrusions 212 for the positioning notches 15. The two positioning notches 15 can better limit the rotation position of the rotor connection seat 21, and it is not easy to produce the phenomenon of rotational offset and dislocation.

[0039] Furthermore, in order to ensure the sealing performance, the rotor connection seat 21 is provided with an annular groove 213 for sleeving the sealing ring.

[0040] In this embodiment, the temperature measurement module 30 includes a temperature sensing probe 31 and a temperature measurement connection plate 32. The temperature sensing probe 31 is inserted into the water flow channel 11, and the temperature measurement connection plate 32 is detachably installed on the joint pipe 10 and can clamp the temperature sensing probe 31.

[0041] In some embodiments, the joint pipe 10 can also be provided with a sterilization component.

[0042] Furthermore, in some embodiments, the joint pipe 10 is also provided with a pressure stabilizing member 40. The pressure stabilizing member 40 can stabilize the water pressure of the water flow and avoid excessive water flow pressure.

[0043] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations and substitutions are all included in the scope defined by the claims of this application.
