[0024] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 and Figure 2 As shown, the utility model provides a touch-sensitive faucet, which includes a faucet body 10, a touch panel 20, a pressure detection component 30, an elastic rubber pad 40 and a control component 60.

[0027] The touch panel 20 has a pressing surface 201 and a mounting surface 202 which are arranged opposite to each other.

[0028] The pressure detection assembly 30 includes a circuit substrate 302 and a pressure sensor 301 welded on the circuit substrate 302. The pressure sensor 301 contacts the mounting surface 202; the pressure detection assembly 30 is electrically connected to the control assembly 60 via a lead wire 303.

[0029] The faucet body 10 is provided with a cavity 101 for setting a water outlet control device. The touch panel 20 is installed at the opening of the cavity 101 through the elastic rubber pad 40, and the pressing surface 201 of the touch panel 20 faces outward. The pressing surface 201 can be deformed by force to drive the pressure sensor 301 fixedly installed on the installation surface 201 to output a signal to the control component 60 after being pressurized. The control component 60 is electrically connected to the solenoid valve set in another cavity of the faucet body 10 through the control line, connecting the water path, and allowing water to flow out from the water outlet 102.

[0030] In this embodiment, the faucet body 10 is a pure copper component or a stainless steel component. For aesthetics, waterproofing and convenient processing, an elastic rubber pad 40 is provided as a support member for installing the touch panel 20.

[0031] The mounting surface of the touch panel 20 is provided with adhesive backing 203, which is bonded to the surface of the elastic rubber pad 40. A snap-fit ​​structure 401 is provided at the connection between the elastic rubber pad 40 and the faucet body 10 to form a concave-convex fit, thereby achieving a fixed connection between the elastic rubber pad 40 and the faucet body 10. At the same time, the bottom surface of the circuit substrate 302 is in contact with the support portion 402 of the elastic rubber pad 40, and the elastic rubber pad 40 provides elastic support for the pressure detection component 30, so that when the touch panel 20 is pressed, the force of the pressure sensor 301 is limited to a suitable range, and then the accurate pressure data of pressing the touch panel 20 can be collected.

[0032] Preferably, to ensure the waterproof effect, a sealing ring 50 is further provided between the elastic rubber pad 40 and the faucet body 10. More specifically, the sealing ring 50 is fixed in the cavity of the side wall of the elastic rubber pad 40.

[0033] The control component 60 can be functionally divided into a touch action recognition unit and a water outlet control unit. The touch action recognition unit is used to fit the pressure waveform data uploaded by the pressure sensor with the pressure training model to provide a touch action recognition result; the water outlet control unit is used to perform water outlet control according to the touch action recognition result. More specifically, the touch action recognition unit includes a microprocessor, and the microprocessor is preset with a pressure training model (pressure waveform model). The collected precise pressure waveform data can be fitted with the pressure training model, and the object that touches the touch panel can be identified as a finger, water flow, etc., to achieve correct recognition and judgment of the operation, such as normal finger touch (single click, double click, long press, etc.), water flow flushing and cleaning, rag wiping and other actions, with high sensitivity, which is impossible for traditional capacitive sensing. At the same time, compared with the traditional capacitive sensing solution, the use of pressure sensors has lower power consumption.

[0034] The water outlet control unit includes a drive circuit, which is connected to the solenoid valve via a cable 601, and drives the solenoid valve to open the connecting water path according to the water outlet control signal of the processor to achieve water outlet.

[0035] In summary, the touch-sensitive faucet of the utility model has the following specific technical effects:

[0036] 1. Compared with the traditional capacitive sensing solution, it has good waterproof performance and lower power consumption;

[0037] 2. High sensitivity, even able to identify tiny pressure changes caused by water drops;

[0038] 3. Based on this circuit and mechanism, combined with software control, touch actions can be accurately identified.

[0039] In other embodiments, the pressure detection component 30 may also be installed on the touch panel 20 in the following manner to detect the pressure acting on the touch panel 20:

[0040] Method 1: The pressure detection assembly 30 is fixedly installed in the cavity of the faucet body 10, with one side of the pressure sensor 301 facing the touch panel 20; a damping material 304 (such as rubber, etc.) with different damping coefficients is set between the pressure sensor 301 and the touch panel 20 to adjust the sensitivity of the pressure detection. Figure 3 shown.

[0041] Method 2: The pressure detection assembly 30 is fixedly installed in the cavity of the faucet body 10, with one side of the circuit substrate 302 facing the touch panel 20, and damping materials 304 with different damping coefficients are arranged between the touch panel 20 and the circuit substrate 302. In this embodiment, the pressure acting on the touch panel 20 is transmitted to the circuit substrate 302 through the damping material 304, so that the circuit substrate 302 is deformed and the pressure is transmitted to the pressure sensor 301. Figure 4 shown.

[0042] Method 3: directly attach one side of the circuit substrate 302 of the pressure detection component 30 to the touch panel 20. Directly transmit the pressure on the touch panel to the pressure sensor through the circuit substrate 302. Figure 5 shown.
