Description

Technical Field

[0001] This utility model relates to the field of faucets, specifically a pull-out faucet. Background Technology

[0002] Pull-out faucets, as an important functional component in modern kitchens and bathrooms, significantly enhance user convenience with their flexible pull-out design. Their basic structure typically consists of three parts: the faucet body, the valve core assembly, and the pull-out hose and spout. The faucet body serves as the main frame, integrating hot and cold water inlet channels and a mixing chamber. The valve core, as the core control component, adjusts the mixing ratio and flow rate of hot and cold water through a mechanical structure. The pull-out hose, made of flexible material (such as stainless steel braided hose or silicone tubing), connects the valve core outlet to the spout and automatically resets after being pulled out using gravity balance or a magnetic attraction device. The spout is often designed with a dual-mode switching structure for both shower and direct current sprays to adapt to different usage scenarios.

[0003] In existing technologies, water flow control in pull-out faucets primarily relies on the mechanical operation of the valve core. Users adjust the mixing ratio of hot and cold water and the flow of water by rotating or pressing the handle to move the ceramic disc inside the valve core. However, this design has significant limitations: water temperature adjustment depends on manual operation based on user experience, lacks a real-time feedback mechanism, and poses a risk of scalding.

[0004] Although sensor control technology has been widely applied in non-pull-out faucets, the integration of sensor switches in existing pull-out faucets is insufficient. The main technical bottlenecks are: traditional valve cores cannot be adapted to electronic control signals, requiring the addition of a solenoid valve assembly within the faucet body, which increases the faucet's size and affects the smoothness of the pull-out action; and there is a lack of water temperature detection solutions, as existing temperature sensors are mostly externally placed in the inlet pipe, making it difficult to monitor the temperature of the mixed water in real time, resulting in insufficient temperature detection accuracy.

The temperature measuring component 32 includes a mounting sleeve 323, which is fitted over the temperature probe 322. The temperature probe 322 includes a radially outwardly extending mounting ring 3222. One end of the mounting sleeve 323 abuts against the mounting ring 3222. The mounting sleeve 323 is threadedly connected to the inner wall of the third port 4323 to press and fix the mounting ring 3222. The third port 4323 forms a radially inner ring 4324, and a sealing ring 324 is provided between the radially inner ring 4324 and the mounting ring 3222. In this embodiment, one end of the mounting sleeve 323 abuts against the mounting ring 3222, causing the mounting ring 3222 to press against the sealing ring 324, thereby achieving a seal.
