Description

Technical Field

[0001] The present invention relates to the field of faucets, and more particularly to an intelligent multifunctional faucet. Background Art

[0002] With the development of society and the improvement of living standards, people's requirements for the quality of life are also increasing. However, the existing traditional basin faucets and kitchen faucets only output cold water or hot and cold tap water, which is difficult to match with high-quality life. With the improvement of living standards, people have put forward higher requirements on the quality of drinking water. In order to meet the needs of the market, faucets that can output multiple types of water have been developed in the prior art, such as a faucet that integrates hot and cold tap water and hot and cold purified water as one disclosed in the patent with authorization announcement number CN218845193U, which includes a faucet body and a control device. The faucet body includes a kitchen faucet structure for outputting hot and cold tap water and a water purification structure for outputting hot and cold purified water. The control device includes a valve core seat and a valve core. The kitchen faucet structure is threadedly connected to the valve core seat, and the valve core is connected to the valve core seat through a pressure cap and a handle. The faucet is an integrated hot and cold tap water and hot and cold purified water. The faucet has flushing water, micro-bubble water and hot and cold water purification functions to meet the various needs of consumers. An electronic control component for fixing the power signal line is arranged above the inner cavity, and a touch panel is arranged above the electronic control component. Through the data exchange between the electronic control component and the water purifier, the water quality, temperature heating and filter life information of the water purifier are displayed on the touch panel. The display information on the panel includes cold water purification button, hot water purification button, inlet TSD value, outlet TDS value, lock button, heating button, water temperature display, water shortage display and filter life display. When in use, select the required water purification state (cold water, hot water, bubble water) and the flow rate and temperature of the purified water to obtain the required purified water.

[0003] However, in the above design, the water purification is completely dependent on the touch panel, and there are many problems in the use of the touch panel, mainly as follows: On the one hand, the touch panel realizes its function by detecting the touch position and touch action, and its probability of misoperation is high. Compared with traditional mechanical buttons, the touch panel does not have the tactile feedback when the physical button is pressed, so that the user may not be able to determine whether he has successfully triggered a certain function during operation, and then repeat the operation, resulting in low efficiency. On the other hand, the manufacturing process of the touch panel is relatively complex, especially the high-precision and high-sensitivity touch panel, which requires the use of advanced materials and manufacturing technology. This makes the manufacturing cost of the touch panel high, which leads to a relatively high price of the equipment using the touch panel. Moreover, when the touch panel of the equipment fails, the maintenance cost is also relatively high, because its maintenance requires professional technicians and equipment.

[0004] Therefore, there is an urgent need for an intelligent multifunctional faucet that does not rely on a touch panel to control the water purification and water discharge of the faucet. Summary of the invention

During the production process, the processing accuracy of the connecting hole is strictly controlled, and the position is accurately calculated to ensure accuracy and adaptability when connected with other components;

[0060] The bottom end of the vertical pipe 41 is coaxially rotatably sealed with the top of the three-way pipe 22. Specifically, the connection can be made through a sealing rotating sleeve structure. The sleeve is made of a wear-resistant and well-sealed rubber material. While ensuring that the vertical pipe 41 can flexibly coaxially rotate relative to the three-way pipe 22, an excellent sealing effect is achieved to effectively prevent water leakage.

[0061] The tap water flow component is an existing structure, which includes a mixing valve, a tap water inlet pipe group, and a water outlet pipe, wherein the mixing valve includes a valve core seat 23, a valve core and a control handle 24, wherein the valve core seat 23 is installed on the horizontal pipe body of the three-way pipe 22 by screws, the valve core is installed on the valve core seat 23, and the control handle 24 is connected to the valve core.

The rotary push-type electronic handle 100 is provided with a display screen, which is used to display information related to faucet water purification, including functions (such as cold water purification, hot water purification or cold bubble water purification, normal temperature water purification), parameters (such as temperature, water volume, etc.), etc. The rotary push-type electronic handle 100 includes a rotary operating end and a press-rebound operating end. When the user rotates the operating end, an electrical signal is output, and the electrical signal is used to switch the water purification function or adjust related parameters. At the same time, the switching operation will be displayed on the display screen. For example, after rotating the rotary operating end to a set angle, the display screen will display the switch from cold water purification to hot water purification. When the user uses it, the user can operate the rotary operating end according to the display screen to switch to the desired function or parameter; when the user presses the press-rebound operating end When the rotary operating end is rotated, an electrical signal is output, which is used to select the required function or parameter and displayed on the display screen. For example, when the rotary operating end is rotated and the display screen displays the hot water purification function required by the user, the user presses the push-to-rebound operating end to select the hot water purification function. Then the user can rotate the rotary operating end again to switch the parameters of the hot water purification, such as temperature and water volume, and press the push-to-rebound operating end to select the required temperature and water volume, and then rotate the rotary operating end again to switch to the water outlet function, and then press the push-to-rebound operating end to discharge water. In actual use, after the intelligent multifunctional faucet is installed on the required countertop, it can be used in conjunction with a control system. The control system is connected to the display screen, the rotary push-type electronic handle 100, and the water purification device to better realize the operation of the entire faucet.
