Description

Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a temperature display faucet. Background Art

[0002] Hot and cold faucets are very common in households. The handle can not only adjust the water flow, but also adjust the water temperature. If there is no temperature display device, the temperature can only be estimated by experience or by touching the water flow with your hand.

[0003] Some thermometers on the market display the temperature through a digital display screen, but this requires power or a hydroelectric generator to be installed on the faucet, and the structure is relatively complicated. The instrument thermometer does not need to be powered on. After the probe senses the change in water temperature, it drives the pointer to change relative to the scale to display the temperature, overcoming the problem of the complex structure of the digital thermometer. Since the probe of the instrument thermometer needs to be inserted into the water cavity, the sealing between the instrument thermometer and the water cavity needs to be guaranteed. In addition, the dial scale of the instrument thermometer needs to face a specific direction as needed for easy viewing, so the problem of the instrument orientation also needs to be solved.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content
