A liquid crystal display screen 7, an audio system 8, and a button 9 are installed on the control valve 1. The button 9 has two, namely, KEY1 and KEY2. A power amplifier module, a Bluetooth module, a voice module, a leakage detection sensor, a digital temperature sensor, a valve motor drive module, and an STM32F103C8T6 control chip are arranged inside the control valve 1; the power amplifier module, the Bluetooth module, the voice module, the leakage detection sensor, the digital temperature sensor, and the valve motor drive module are all connected to the STM32F103C8T6 control chip.

[0033] At the same time, please refer to the figure, the smart shower device based on STM32 has a control circuit corresponding to the above module, which includes a power amplifier circuit PA, a valve drive circuit VD, a main control circuit CTRL, a button circuit F4, a DS18B20 digital temperature sensor circuit F8, a buzzer circuit F9, a leakage detection circuit F10, a reset circuit RSTC, a power filter circuit PFC, a clock circuit CLK, a crystal oscillator circuit XTAL, a startup mode selection circuit BOOT and a download circuit SWD.

[0035] In the above, a quick human-computer interaction can be achieved through the voice recognition module, the water temperature can be accurately controlled by controlling the hot and cold water inlet valves, and the water speed can be accurately controlled by controlling the main valve. The user can play music through the mobile phone connected to Bluetooth. At the same time, the user can use the buttons to manually adjust the water temperature and water speed. The OLED module can display the current water temperature and water speed in real time. The leakage protection circuit is introduced, which is safer to use.

[0036] The smart shower system based on STM32 is first powered by a power supply. At this time, the power indicator light is on and the entire system is initialized, including initializing the voice recognition module, initializing the DS18B20 circuit, initializing the Bluetooth module circuit, initializing the OLED circuit, and initializing the main control chip. Then the entire system starts to run, the main control chip starts to work normally, the temperature sensor starts to collect real-time water temperature, the OLED screen displays the real-time water temperature and water speed, the voice recognition circuit stands by to detect the user's voice command and pass the command to the main control chip to achieve the effect of voice control, the Bluetooth module circuit starts to connect the user's terminal device for data communication and passes the information to the main control chip. The main control chip drives the speaker to output the corresponding audio through the power amplifier circuit. When the user says "a little hotter", the main control chip will control the hot water valve to open larger and the cold water valve to open smaller through the valve drive circuit. When the user says "a little colder", the main control chip will control the hot water valve to open smaller and the cold water valve to open larger through the valve drive circuit. When the user says "adjust to X degrees", the main control chip will control the hot water valve to open smaller and the cold water valve to open larger through the valve drive circuit. The water valve and the cold water valve are adjusted to the corresponding temperature. When the user says "a little higher", the main control chip will control the main valve to open higher through the valve drive circuit. When the user says "a little lower", the main control chip will control the main valve to open lower through the valve drive circuit. When the user says "close", the main control chip will control the main valve to close through the valve drive circuit. When the user says "open", the main control chip will control the main valve to open through the valve drive circuit. When the user says "optimal water temperature", the main control chip will control the hot water valve and the cold water valve to the temperature with the longest use time last time through the valve drive circuit. In addition, the user can also control the audio playback through voice commands such as "previous song", "next song", "pause", and "play". In addition, the user can also customize voice commands through the mobile phone.

[0037] In addition, a clamp 11 is added to the control valve 1, and the control valve 1 and the clamp 11 are connected by a plastic support rod 10. When the shower head 3 is removed from the hanger on the wall, it can be directly clamped by the clamp 11. In this way, when washing hair alone or bathing children, there is no need to hold the shower head 3 by hand to lower the height, and the plastic support rod 10 can adjust the height of the shower head 3.

[0038] Embodiment 1

[0039] See also Figure 3-4 The clamp 11 is composed of a disc 1101 and two plastic clamps 1102. The two plastic clamps 1102 are symmetrically distributed on the disc 1101. The plastic clamps 1102 are arc-shaped. The clamp 11 has the same structure and function as the pendant equipped with the bathing device itself, and both are used to clamp the shower head 3.

[0040] Embodiment 2

[0041] See also Figure 5-6The clamp 11 is composed of a disc 1101 and two elastic sheets 1103. The two elastic sheets 1103 are symmetrically distributed on the disc 1101. The clamping space formed by the two elastic sheets 1103 in a top view is thick in the middle and thin at both ends. The difference between this embodiment and the first embodiment is that the clamp 11 in this embodiment can be used not only to clamp the shower head 3, but also to clamp the water pipe 2. Under the action of the plastic support rod 10, even if the shower head 3 falls from a high place, the clamp 11 can clamp the water pipe 2 to prevent the shower head from falling directly on the ground.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
