What is a thermostatic shower

Thermostatic shower is another name for a thermostatic faucet for showers, also known as a thermostatic shower faucet or a thermostatic shower faucet. In the home, there are generally four places to use hot and cold water mixing faucets: kitchen, wash basin, bathtub, shower room.
Among them, because the mixed warm water used for the shower is sprayed directly on the human body through the shower, maintaining a constant temperature can greatly improve the safety and comfort of the shower, and the use of a constant temperature mixed faucet equipped with a shower head can achieve this purpose.

The earliest hot and cold water mixing faucet is the double handle mixer, the user needs to turn the knob that controls cold and hot water to adjust the intake of hot and cold water, so as to mix into warm water that requires temperature; The second generation of hot and cold water mixing faucet is a single lever mixer, its core is a ceramic plate temperature control valve core, the user swings the handle left and right to adjust the temperature of the mixed water, and the up and down swing handle can adjust the amount of water output. However, when the water pressure of hot or cold water suddenly changes, or the temperature of hot water suddenly changes, the above two faucets must be manually operated to readjust the water temperature.
The thermostatic faucet can automatically balance the water pressure of cold and hot water in a very short time through the thermostatic adjustment valve core that comes with the faucet, so as to maintain the stability of the outlet water temperature, and there is no need for manual adjustment at all.
Thermostatic faucets first appeared in Europe, and in 2014, there were two main automatic temperature adjustment methods, which adopted different thermostatic valve cores:
One is a paraffin element (Wax Element) spool.
The paraffin temperature sensing component works by pouring high-purity special paraffin wax into a small copper container covered with a rubber sensor sheet. Due to the change of water temperature, the volume of paraffin wax in the container also increases and shrinks, and then the mixing ratio of hot and cold water is adjusted by driving the spring to push the piston through the sensing plate at the mouth of the container. In 2014, this constant temperature valve core was mainly adopted by European manufacturers.
Another thermostatic spool uses Shape Memory Alloys (SMA) springs.
The most important part of the SMA thermostatic valve core is the shape memory alloy spring, which is made of nickel-titanium (Ni-Ti) alloy to change its shape by sensing the temperature of warm water after mixing, thereby pushing the piston to adjust the mixing ratio of hot and cold water. The SMA thermostatic spool reacts extremely fast and reacts extremely sensitively around 40°C, which can meet the needs of users for stepless fine-tuning. In 2014, this thermostatic valve core was mainly adopted by Japanese manufacturers.
Since the constant temperature valve spool is a very precise device, no matter which form is used, the internal processing of the valve core constant temperature faucet shell is also very precise, and the tolerance of all internal processing dimensions should be limited to ±0.1mm, and the tolerance of important dimensions must be controlled within ±0.05mm.
Thermostatic shower faucets are suitable for showers in homes, hotels, public baths, and barber shops where water pressure is constantly changing.
