Description

Technical Field

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

[0002] A faucet, also known as a water valve, mainly functions to control the size of the water flow switch, including increasing / decreasing the water flow size and opening / closing the water flow. Currently, faucets are often used in household life. For example, a household water heater. When the faucet of the water heater discharges hot water, a large amount of water vapor will be generated, so it is also called a steam faucet. Of course, steam faucets are also used in other life or work scenarios.

[0003] For steam faucets, in many usage scenarios, a temperature sensor is required to measure the current steam or water flow temperature of the steam faucet through the temperature sensor. The temperature sensor set on the steam faucet needs to upload the measured temperature data, so the temperature sensor needs to be electrically connected to the main control board or the upper computer through a cable. Moreover, the steam temperature of the steam faucet may be relatively high. If the cable is directly placed within the steam range, it is easy for the cable to be affected by heat, resulting in damage to the cable or even melting of the cable material and causing pollution. If the steam faucet is applied to some food (such as beverages) equipment, there may also be potential food safety problems. Therefore, it is necessary to isolate the steam and the cable well to avoid the cable being affected by the steam. Currently, existing steam faucets often do not notice this problem and do not have corresponding structures; or, existing steam faucets use cables made of high-temperature resistant materials to solve this problem, but this method is costly.

[0004] In addition, the pipeline connecting the steam nozzle in existing steam faucets is often a single pipeline, and the pipeline used is a stainless steel metal pipe. The single stainless steel pipe is easily affected by steam. Once the steam sprays and contacts the metal pipe, due to the relatively high steam temperature, the outer wall temperature of the metal pipe is also relatively high, and the outer wall temperature will be higher than the human body temperature. If a user (or operator) accidentally touches the metal pipe, it is easy to cause scalding and trigger a safety accident. Content of the Utility Model
