In order to describe the structure and characteristics of the present utility model in detail, the following preferred embodiments are given below and described with reference to the accompanying drawings.

As shown in Figures 1 to 3, an electronic water temperature display 1 provided by the present invention includes a pipe body 10, a control device 20, a temperature sensor 30 and a display device 40, wherein:

The pipe body 10 is provided with threaded sections 11 at both ends of the pipe body 10 for connection with showers and water pipes. The pipe body 10 can be made of commonly used water pipe materials such as copper, stainless steel, hard plastic or PVC.

The control device 20 includes a circuit board arranged in the tube body 10, and the circuit board is provided with a main logic chip 21, as shown in Figure 4, the main logic chip 21 is an instruction type microcontroller, especially equipped with a liquid crystal display Reduced Instruction Microcontroller for drives. For example, the TM8726 chip produced by Ten Speed Technology is a four-bit single chip specially designed for power-saving battery applications. The chip contains ROM, RAM, Clock, I/O and LCD drivers. The working voltage can be from 1.5 V to 5V, the internal Data Bus is 8 bits, and each instruction is 16 bits. It is a simplified instruction architecture (RISC), that is, each row of instructions occupies 2 Bytes (16 bits), and the efficiency is quite high. Of course, the present invention can also adopt any microcontroller known in the art that can realize the same function. The circuit board is also provided with a power supply 22 for supplying power to the main logic chip 21. The power supply 22 can adopt button batteries and dry batteries of other types, such as AAA, AA, etc., or reusable rechargeable batteries. Since the control device 20 is disposed in the pipe body 10, it needs to be waterproofed. The waterproof treatment is to use soft materials such as PVC or rubber to make a waterproof sealing ring, set it in the gap between the control device 20 and the pipe body 10 to prevent water infiltration, and then apply some waterproof grease such as silicone grease ), etc., to obtain a better sealing effect. Ultrasonic melting technology can also be used to weld and seal the contact surface between the plastic shell and the shell. The utility model can adopt various existing waterproof treatment measures, and is not limited to the above methods.

The temperature sensor 30 , the probe is arranged in the pipe body 10 , detects the temperature of the water flowing through the pipe body 10 , and inputs the measured data into the main logic chip 21 of the control device 20 .

The display device 40 is disposed on the outer surface of the pipe body 10 after waterproof treatment, and receives and displays the temperature data output by the control device 20 . The display device 40 may be a liquid crystal display or an LED display.

As shown in FIG. 5 , the control device 20 of the present invention can also be connected with an alarm device 23 . Alarm device 23 can adopt various modes such as sound alarm device, luminous alarm device or vibration alarm device that can attract the user's attention, and both can only be provided with a kind of device wherein, also can be provided with multiple devices. Various alarm devices are arranged on the circuit board, and its connection methods can be completed by those of ordinary skill in the art, and will not be described in detail here. The upper and lower limits of the temperature are preset in the main logic chip 21. Once the temperature measured by the temperature sensor 30 exceeds the upper and lower limits, the main logic chip 21 will issue an alarm command and start the alarm device 23 to alarm. In order to facilitate the user to set the upper and lower limit temperature, a button 24 connected to the main logic chip 21 can also be set on the front panel of the display device 40 or on the adjacent tube body 10 to modify the upper limit temperature set in the main logic chip 21. , The lower limit temperature value.

The display device 40 of the present invention can also include an illuminating device 41, which is arranged on one side or around the display device 40, so that the user can clearly see the temperature displayed on the display device 40 even in a dimly lit bathroom. The illuminating device 41 may adopt high-brightness, low-energy-consumption LED lamps. In order to achieve the effect that the lighting device 41 is automatically turned on when water flows through, the main logic chip 21 is also connected to a water flow sensor 26 . The probe part of the water flow sensor 26 is arranged in the pipe body 10, and the signal of water flowing through the pipe body 10 can be input to the main logic chip 21 at any time, and the main logic chip 21 controls the opening of the lighting device 41 according to the received water flow signal. The utility model can also not use the water flow sensor 26 to turn on the lighting device 41, but a vibration sensor (not shown) connected with the main logic chip 21 is set in the pipe body 10. The vibration generated by the flow can be detected by the vibration sensor, and the information is transmitted to the main logic chip 21, and the main logic chip 21 sends an instruction to turn on the lighting device 41, so that the user can observe the temperature of the water.

The working process of the present utility model is shown in Figure 6, and the temperature sensor 30 transmits the detected water temperature to the main logic chip 21 in real time, and after processing, it is sent to the display device 40 (liquid crystal display) for display. At the same time, the main logic chip 21 also determines whether to turn on the lighting device according to the signal transmitted by the water flow sensor 26 (or the vibration sensor). The main logic chip 21 will also compare the water temperature data detected in real time with the upper and lower limit data preset or input by the user. Once it is concluded that it is not in the upper and lower limit range, the alarm device 23 needs to be activated immediately to report to the police to ensure User Safety.

The installation of the utility model is very convenient, as shown in Fig. 1 and Fig. 2, the user only needs to loosen the screws connecting the water pipe at the end of the shower, and connect the threaded sections 11 at both ends of the utility model to the end of the shower and the screw of the water pipe respectively. Then, the utility model can be installed between the two without other complicated operations, which greatly simplifies the complex installation process of the existing shower thermometer that needs to be installed on the wall with a display device, and anyone can easily complete the assembly , It relieves the user's worries about the inconvenience of installation when purchasing. Moreover, the utility model can be installed in any threaded place in the shower and the hot water pipeline, such as being connected between the faucet and the water pipe (as shown in Figure 7), and can also be connected between the hot water pipe in the wall Between the water outlet of the water heater and the shower water pipe (as shown in Figure 8), it can also be connected between the water heater outlet pipe and the water pipe (as shown in Figure 9).

The utility model can also adopt the mode of being directly installed on the shower. As shown in Figure 10, the shower head with electronic water temperature display provided by the utility model includes: a shower head 50, a display device 40 after waterproof treatment is embedded in its back, a temperature sensor 30 and a water flow The probe of the sensor 26 is arranged in the inner cavity of the shower, and the control device 20 is embedded in the back of the shower 50 after being waterproofed. The only difference between this embodiment and the above-mentioned embodiment is that the pipe body 10 is not needed, but the control device 20 and the display device 40 are directly embedded on the shower 50, and the user only needs to replace a shower, and the installation more convenient. In this embodiment, a vibration sensor (not shown) can also be arranged on the shower 50. Once the user holds the shower 50 in his hand, it can be detected by the vibration sensor, and the information can be transmitted to the main logic chip. 21. The main logic chip 21 issues an instruction to turn on the lighting device 41, so that the user can observe the temperature of the water.

To sum up, this embodiment can also realize the same display of water temperature as the previous embodiment, and the function of alarming when the water temperature exceeds or falls below a preset temperature.
