[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] Example:

[0025] As attached Figure 1 To the attached Figure 5 As shown:

[0026] The utility model provides a water temperature sensor device for a gas water heater, comprising a measuring tank 21 opened in a water tank 11, a buoy 13 provided in the measuring tank 21, a water temperature sensor 14 installed on the bottom surface of the buoy 13, and since the water temperature sensor 14 is arranged in the outer shell of the water tank 11 rather than in the water tank 11, it is easier to disassemble and assemble, and the presence of the buoy 13 enables the water temperature sensor 14 to be kept below the water level, so that the reading of the water temperature sensor 14 is more accurate. Through grooves 23 connecting the water inlet pipe 151 and the water outlet pipe 152 are respectively opened on both sides of the water tank 11, and the hot water heated by the heat exchanger is discharged from the water inlet pipe 151. It flows into the water tank 11 and flows out from the outlet pipe 152 when needed; two groups of connecting grooves 22 are provided on one side of the water tank 11, and the two groups of connecting grooves 22 are connected to the measuring groove 21. The measuring groove 21 is connected through the two groups of connecting grooves 22, so that the measuring groove 21 can be connected to the water tank 11, so that the water level in the measuring groove 21 is kept level with the water level in the water tank 11. A fixing component is provided on the top of the measuring groove 21, and a signal line 37 is connected to one side of the water temperature sensor 14. A sleeve 24 is provided at the connection between the water temperature sensor 14 and the signal line 37, which improves the sealing of the connection between the water temperature sensor 14 and the signal line 37.

[0027] Among them, see Figures 1 to 3As shown, the fixed component includes a top cover 32, the bottom side of the top cover 32 is fixedly connected to the base 31, and the base 31 is connected to the buoy 13 through a nylon rope 35. When the top cover 32 is opened, the base 31 will drive the nylon rope 35 to pull out the buoy 13, which is convenient for workers to disassemble when maintenance and replacement are required.

[0028] Among them, see Figure 3 As shown, a protrusion 33 is provided on the side of the base 31, and an interface hole 25 is provided on the top of the measuring groove 21. Through the setting of the protrusion 33 and the interface hole 25, the fixing device can be more firmly set in the measuring groove 21. At the same time, such a combination can ensure that it is fixed while being convenient for disassembly. The pull ring 34 is provided on the top cover 32 to facilitate the removal of the entire fixing device.

[0029] Among them, see Figure 3 As shown, a group of limit plates 38 are provided under the base 31. The limit plates 38 are provided with a group of limit grooves 28. The nylon rope 35 is passed through the limit grooves 28. The existence of the limit plates 38 can prevent the buoy 13 from hitting the top and colliding when the water level is too high.

[0030] Among them, see Figures 2 to 3 As shown, two groups of slide grooves 26 are opened on the inner side of the measuring groove 21, and sliders 36 are provided on both sides of the buoy 13. The sliders 36 are slidably connected to the slide grooves 26. Through the cooperation between the slide grooves 26 and the sliders 36, a guiding role is played, which can further stabilize the buoy 13 and the water temperature sensor 14.

[0031] Among them, see Figure 1 As shown, a high-temperature silicone filler 39 is filled between the sleeve 24 and the signal line 37. The high-temperature silicone filler 39 can still maintain good waterproof ability in a high-temperature environment, so that the connection between the signal line 37 and the water temperature sensor 14 will not leak.

[0032] Among them, see Figure 4 and Figure 5 A card slot 27 is provided on the inner side of the measuring slot 21, and the signal line 37 is stuck in the card slot 27. The fixed signal line 37 can reduce the impact on the buoy 13. For example, if the buoy 13 is stuck, the buoy 13 cannot float up or fall smoothly. A connecting hole 29 is provided on the outer shell of the water tank 11, and the signal line 37 passes through the connecting hole 29. The diameter of the connecting hole 29 should be equal to that of the signal line 37. If it is inconsistent, waterproof tape should be used to wrap it so that the signal line 37 just blocks the connecting hole 29; since the fixing device at the top is detachable, the signal line 37 passing through the fixing device may cause water leakage, so it is chosen to pass through from the side.

[0033] The specific usage and function of this embodiment are as follows: when using the device, by opening the measuring slot 21, the buoy 13 and the water temperature sensor 14 connected to the fixing device by the nylon rope 35 are placed in the measuring slot 21, the water temperature sensor 14 and the buoy 13 are slidably connected to the slide slot 26 by the slider 36, the signal line 37 is inserted into the slot 27, and then the protrusion 33 and the interface hole 25 are aligned, the fixing device is fitted into the outer shell of the water tank 11, and after water is introduced, the measuring slot 21 and the water tank 11 are connected to form a communication. The device makes the liquid surface level, and the buoy 13 floats with the liquid surface, so that the water temperature sensor 14 can keep working normally below the liquid surface, which solves the problem that the traditional water temperature sensor cannot detect the water temperature because the water level in the water tank 11 drops below the sensor, so there is a problem of inaccurate detection in actual use; when disassembling, it is only necessary to twist and pull the pull ring 34 to take out the fixing device, and the buoy 13 and the water temperature sensor 14 can be taken out simultaneously, which reduces the complexity of disassembly and assembly of the device and improves the convenience during maintenance.

[0034] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.
