Detailed ways

The utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

The utility model provides a touch-sensing faucet structure, as shown in Figures 1 to 7, including a faucet housing 1, an intelligent control module 2 and a valve box 3. One end of the faucet housing 1 is provided with a water outlet, and the other end is provided with a water outlet. A water inlet is provided, and the inside of the faucet housing 1 is a water outlet channel connecting the water inlet and the water outlet. The other end of the faucet housing 1 is installed on the basin 11 and is provided with an insulating component between the faucet housing 1 and the basin 11 . The intelligent control module 2 is located at one end of the faucet housing 1 with the water inlet. The intelligent control module 2 is electrically connected to the valve box 3 and transmits signals to control the water outlet and water stop.

The key point of this case is that the entire outer surface of the faucet housing 1 is designed as a triggering surface for touch sensing, and the sensing range is large. The specific implementation method is as follows: As shown in Figure 1, the outer surface of the faucet shell 1 is a non-insulating surface. The faucet shell 1 can be made of a non-insulating material as a whole, or only the outer surface of the faucet shell 1 is provided with a non-insulating material. Non-insulating plating to achieve its conductive properties. The faucet housing 1 is electrically connected to the intelligent control module 2 and the valve box 3 in any way. The valve box 3 has a built-in solenoid valve and is electrically connected to the intelligent control module 2 through electronic wires or wireless communication modules to control the waterway switch. When the human body touches any position on the outer surface of the faucet housing 1, the intelligent control module 2 is triggered. The intelligent control module 2 transmits the water outlet signal to the valve box 3, and the valve box 3 controls the water outlet.

As shown in Figures 4 and 5. The other end of the faucet housing 1 is installed on the basin 11 through a mounting assembly. The specific mounting assembly includes a flange seat 4 and a locking tooth tube 5 . In this embodiment, the locking tooth tube 5 is an externally threaded locking tooth tube 5. The faucet housing 1 and the flange seat 4 are provided with internal threads. The lower end of the locking tooth tube 5 is fixed to the lower part of the basin 11. The flange seat 4 is set on the upper end of the locking tooth tube 5 and is threadedly connected to the faucet housing 1, so that the faucet housing 1 is installed on the basin 11.

In order to ensure the electrical connection between the faucet housing 1 and the intelligent control module 2, the flange base 4 must also be electrically connected to the faucet housing 1 and the intelligent control module 2. Therefore, if the flange seat 4 is made of non-insulating material or its outer surface is provided with a non-insulating electroplating layer, then the flange seat 4 can be directly connected to the faucet shell 1 to achieve electrical conduction; 4 is an insulating material and cannot conduct electricity independently. It can be electrically connected to the faucet shell 1 through an electronic wire to achieve conduction.

This case does not limit the electrical connection between the intelligent control module 2 and the flange base 4. It is preferred to use an elastic ejector pin structure 7. As shown in Figure 3, the intelligent control module 2 is provided with an elastic ejector pin structure 7. When the When the flange base 4 is fastened to the intelligent control module 2, the elastic ejector pin on the elastic ejector pin structure 7 contacts the flange base 4 and is electrically connected with the flange base 4, so that the intelligent control module 2 and the faucet are connected The housing 1 realizes electrical connection.

In order to prevent the signals from the faucet housing 1 and the intelligent control module 2 from being conducted to the basin 11, causing false interference and affecting the sensing and control accuracy, this case also has an insulating component between the faucet housing 1 and the basin 11, as shown in the figure As shown in 3, the insulation assembly includes an annular insulating base 6, which is located on the upper surface of the basin 11, thereby electrically insulating the basin 11 from the faucet housing 1 above it.

In addition, the locking tube 5 will be electrically connected when connected to the flange base 4, and the locking tube 5 is usually made of conductive metal and will be in contact with the basin 11 to conduct electricity during installation. Therefore, the inventors insulated The inner ring of the base 6 extends axially to form an insulating boss 61 that wraps the locking tooth tube 5 to separate the basin 11 from the locking tooth tube 5 and thereby electrically insulate the faucet housing 1 from the locking tooth tube 5 .

The insulation component also includes an insulating isolation pad 9 or an insulating isolation ring. This is because when fixing, it is necessary to use the fixing piece 10 to cooperate with the locking tooth tube 5 to lock the basin 11 and the faucet shell 1 under the basin 11 to prevent the faucet shell 1 from shaking. When the fixing part 10 is made of non-insulating material or the surface is plated with a non-insulating coating, an insulating isolation pad 9 or an insulating isolation ring should be provided between the faucet shell 1 and the basin 11 to prevent the faucet shell 1 from intelligent control. The assembly communicates with the basin 11 through the locking tooth tube 5 .

The above-mentioned insulating components are provided to electrically insulate the faucet shell 1 and other conductive parts from the basin 11 to avoid false interference of signals and improve the control accuracy of the faucet's water inlet and outlet. In addition, during daily use, due to water spray, Due to splashing and other reasons, water often accumulates on the surface of the basin 11, and the user may get an electric shock. Although the power is very small, in order to avoid the possibility of electric shock as much as possible and improve the safety of use, the setting of the insulating components is very important. important.

The intelligent control module 2 in this case uses an MCU (Microcontroller Unit) controller.

In order to facilitate the installation of the intelligent control module 2, the inventor also provides an annular light ring 8 between the flange base 4 and the insulating base 6, and the intelligent control module 2 is placed in the annular light ring 8. The flange base 4, the annular light ring 8, the intelligent control module 2, and the insulating base 6 can be fixedly connected through the locking barrel 5. The flange base 4 is fixedly connected to the faucet shell 1, and then fixed through the locking barrel 5. On the basin 11, lock the connection.

The touch-sensitive faucet structure also includes a power module 12. The power module 12 is electrically connected to the valve box 3 and supplies power to the valve box 3 to ensure the normal use of the faucet structure. The power module 12 can be a battery box, a power adapter, a rechargeable battery, etc.

The working principle of this touch-sensitive faucet structure is as follows:

1. In terms of structure:

The faucet shell 1 is made of non-insulating material or has a non-insulating electroplating layer on its outer surface, and is electrically connected to the intelligent control module 2 in various ways, so that the outer surface of the faucet shell 1 is a triggering surface for touch induction, and the faucet shell 1 1 needs to be insulated from the basin 11 to prevent signals from being conducted to the basin 11 and causing false interference.

2. Electronic working principle:

Working principle: The human body is a conductor. When a finger approaches or comes into contact with the touch area of the faucet housing 1, the capacitance will increase. The change in capacitance will slightly change the frequency of the internal induction oscillator. The change in frequency can be sensed by measuring it. Touch action. The reference clock can generate a fixed time period through an internal programmable divider. During this time period, the action of the touch key can be determined by counting the clock cycles generated by the sensing oscillator within this fixed time period.

Environmental adaptation: As shown in the flow chart in Figure 7, an environment correction is performed when power is first turned on. The intelligent control module sends a command to close the solenoid valve. The indicator light flashes 5 times, and then enters sleep state to determine whether the sleep time reaches 32 milliseconds. Otherwise, it goes to sleep again; if it is, it enters the valve opening state, and then determines whether it enters the valve opening state.

Water discharge protection: If the valve enters the open state, the valve opening time is determined. If the valve open state reaches 180 seconds, that is, a single cumulative water discharge is 180 seconds, an instruction to close the solenoid valve and the indicator light will be sent to automatically stop the water discharge to prevent forgetting to turn off the water. A water leak has occurred.

If the valve opening time does not reach 180 seconds, it will be judged whether there is induction. If there is no induction for 240 milliseconds continuously, the environment will be calibrated, and then it will be judged whether there is no induction for 630 milliseconds continuously. If so, it will enter the dormant state, otherwise it will enter the valve opening state. The program is set to calibrate the environment value and update the reference value every 240 milliseconds (the time can be adjusted according to the project) before entering the sensing state, so as to adapt to the parameters in different installation and use environments, thereby filtering out non-artificial errors caused by environmental reasons. interference and reduce false triggering.

If the valve opening time does not reach 180 seconds, it is judged that there is induction. Then by judging the induction time, it is judged whether the induction is effective. The judgment method is as follows:

Software reset: When it is in the sensing state continuously for ≥5 seconds, it is judged that the environment has changed significantly or it is not used normally. At this time, the software is reset to recalibrate the current environment and restore the normal use of the product.

Accidental water discharge protection: If the single induction time is less than 2 seconds, it is judged that the induction is valid, and the command to close the solenoid valve and the indicator light is sent to stop the water discharge; if the induction time is ≥ 2 seconds and < 5 seconds, the induction is judged to be invalid, and the valve opening preparation is re-entered. , to prevent the water from being accidentally triggered when swinging the faucet.

The above are only preferred embodiments of the present utility model and are not restrictions on the design of this case. All equivalent changes made based on the key design elements of this case fall within the scope of protection of this case.
