Description

TECHNICAL FIELD

[0001] The utility model relates to the field of faucet. More specifically, the utility model relates to a kind of intelligent multifunctional faucet. BACKGROUND

[0002] With the development of society and the improvement of living standards, people's requirements for life quality also improve. However, the existing traditional basin faucet and kitchen faucet only output cold water or cold and hot tap water, which is difficult to match well with high-quality life. With the improvement of living standards, people have higher requirements for drinking water quality. In order to meet the needs of the market, the existing technology has developed a water faucet that can output multiple types of water. For example, a water faucet integrated with cold and hot tap water and cold and hot clean water is disclosed in a patent with the authorization announcement number CN218845193U. The water faucet includes a faucet body and a control device. The faucet body includes a kitchen faucet structure for cold and hot tap water output and a clean water structure for cold and hot clean water output. The control device includes a valve core seat and a valve core. The kitchen faucet structure is threadedly connected with the valve core seat. The valve core is connected with the valve core seat through a pressure cap and a handle. The water faucet is a water faucet integrated with cold and hot tap water and cold and hot clean water. It also has a flushing water outlet, a micro-bubble water outlet, and a cold and hot clean water function to meet the needs of consumers. An electric control assembly for fixing a power signal line is arranged above the inner cavity. A touch panel is arranged above the electric control assembly. The water quality, temperature heating, and filter core life information of the water purifier are displayed on the touch panel through data exchange between the electric control and the water purifier. The display information on the panel includes a cold clean water key, a hot clean water key, an inlet TDS value, an outlet TDS value, a lock key, a heating key, a water temperature display, a water shortage display, and a filter core life display. When using, the required clean water state (cold water, hot water, and bubble water) and the flow rate and temperature of the clean water are selected to obtain the required clean water.

[0003] However, the above design relies entirely on the touch panel for selecting clean water. The touch panel has many problems during use, mainly as follows: on the one hand, the touch panel realizes functions by detecting touch position and touch action, which has a high probability of misoperation. Compared with traditional mechanical keys, the touch panel does not have the tactile feedback when the physical key is pressed, so the user may not be able to determine whether they have successfully triggered a function and repeat the operation, resulting in low use efficiency. On the other hand, the manufacturing process of the touch panel is relatively complex, especially for high-precision and high-sensitivity touch panels, which require advanced materials and manufacturing techniques. This makes the manufacturing cost of the touch panel relatively high, resulting in a relatively high price of the equipment using the touch panel. Moreover, when the equipment has a touch panel failure, the maintenance cost is also relatively high because professional technicians and equipment are required for maintenance.

[0004] Therefore, there is an urgent need for a non-touch panel to control the water outlet of a faucet. Utility model content
