[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figure 1-4 As shown, the utility model provides an integrated water flow sensor, including a tube body 1, a water tank connector 2 is provided at the first end of the tube body 1, a water inlet connector 3 is provided at the second end of the tube body 1, a water flow pulse signal component 8 is installed at the inner middle part of the tube body 1, and a memory alloy spring assembly 7 is provided between the water tank connector 2 and the water flow pulse signal component 8. By providing the water tank connector 2, the integrated water flow sensor can be directly connected to the water inlet of the water tank, and the water inlet connector 3 can be directly connected to a conventional water pipe, so that the integrated water flow sensor can be installed on any water heater, and has good versatility.

[0019] Specifically, the water flow pulse signal component 8 adopts a commonly used product on the market, with a water wheel blade, and detects the water flow through the rotation of the water wheel blade. After the water flow is detected, a signal is output, which can control the water heater to start working. The water tank connector 2 and the water inlet connector 3 are both universal standard connectors. The diameter and length of the pipe body 1 can be adjusted as needed to meet the space for installing internal components. A temperature sensor 4 is also installed in the pipe body 1 to detect the temperature of the water entering the water tank.

[0020] In this embodiment, if Figure 1 As shown, the water flow pulse signal component 8 is electrically connected to the outside through a signal line 6 embedded in the side wall of the tube body 1, so as to facilitate the water flow pulse signal component 8 to transmit signals to the outside.

[0021] In this embodiment, if Figure 2-4 As shown, the water inlet connector 3 is sleeved and fixed on the outside of the second end of the pipe body 1, which is convenient for the installation and fixation of the water inlet connector 3. The water inlet connector 3 and the pipe body 1 can be made of different materials, and the two can be fixedly connected by welding or other methods.

[0022] In this embodiment, if Figure 2 As shown, a side tube is provided on the side wall of the tube body 1 along the radial direction, a safety valve 9 is installed in the side tube, and a safety drain 10 is provided on the side wall of the side tube, which can improve the safety of the water flow sensor. A mounting seat 5 is provided on the outside of the tube body 1, and a T-shaped slot with one end open is provided on the mounting seat 5 for convenient additional fixing.

[0023] In this embodiment, a filter screen 11 is installed inside the second end of the tube body 1 to prevent debris from entering and causing blockage.

[0024] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
