Description

The core device of a multifunctional faucet

Technical field

The invention relates to a multifunctional faucet, in particular to a core device of the multifunctional faucet.

Background technique

At present, a multi-functional faucet is obtained by using (220V) mains electricity to directly act on tap water through a graphite electrode resistant to electrochemical corrosion. It has the multi-functions of "instant heating, magnetization, and sterilization". Dry burning", due to the inherent characteristics of "magnetization" and low surface energy of graphite, scale induration is simulated. As a "multifunctional faucet", it has unique advantages. Its core device is a pair or a group of electrodes. The patent "a "Multi-functional faucet" (patent number: ZL201220226509.4) provides such a core device. In this patent, a group of electrodes are fixed at a certain distance in an insulated and vertically placed container with a closed top, and a "cross" is formed between the electrodes. Groove" water channel, the spacing of "cross groove" is 2-6mm, and a "vertical lift exhaust port" is set in the middle of "cross groove", and the "vertical lift exhaust port" can be changed by changing the upper part of the container" The size of the "air chamber" is used to change the "draft" area of the electrode, thereby adjusting the size of the power to adapt to different water qualities. However, it has such problems. First, the "core device" must be used "vertically", otherwise the power adjustment method It will not be effective, which makes its structure have greater limitations. Furthermore, for the heating power of the "core device", the hardness of the water, the relative projected area of the electrodes and the load per unit projected area are proportional to the heating power. Proportional, the electrode spacing is inversely proportional to the heating power, among them, for the "multifunctional faucet", the "water hardness" in nature ranging from 40-800mg/L (calculated as COCa ₃ ) is an uncontrollable variable, and " The load per unit area should also be regarded as an uncontrollable variable, especially for graphite electrodes. Practice has shown that a reasonable unit area load should not be greater than 160W/cm ² . Excessive surface load will affect the service life of the electrode, (surface load 200W / ^cm2 , continuous use for 10 hours, the electrode loss exceeds 1%) The other two adjustable variables are "electrode spacing", and the other is "relative projected area". "That is to adapt to different water qualities by adjusting the "relative projected area" under the condition of a fixed "electrode spacing" (2-6mm). 3.4kW as an example) If the "electrode distance" is set to 2mm for 40mg/L softer water, the power of 3.4kW is obtained. When it corresponds to harder water (800mg/L), adjust the power to 3.4kW when "Load" will increase nearly 20 times, which will cause serious wear and tear on the electrodes. If the "electrode distance" is set to 6mm for 800mg/L hard water, the power will be 3.4kW, when it corresponds to soft water (40mg/L) , when the power is adjusted to 3.4kW, the "relative projected area" will increase nearly 20 times, making the bulky, and at the same time causing the adjustment mechanism to be cumbersome. Or based on harder water quality, it should be To adapt to the water quality with large-span changes, it will bring the disadvantages of bulky and cumbersome adjustment mechanism or shorten the service life of the electrode.

Contents of the invention

The present invention provides a core device of a multifunctional faucet, which determines a relative projected area of 25 square centimeters (136W per square centimeter load) on the basis of 3.4kW power, and actually measures relatively soft water quality (40mg/L). When the distance is -1.1mm, the power can reach 3.4kW. The measured water quality is relatively hard (800mg/L). When the distance reaches 10.5-10.6mm, the power can reach 3.4kW. That is, if the water quality of 40-800mg/L is to meet the required The power is 3.4kW, which can be realized only by adjusting the electrode spacing from 1.0mm to 10.6mm. Its structure does not limit the use orientation. Since the invention adapts to different water quality by adjusting the electrode spacing, it maintains a relatively reasonable surface power Load, although the spacing adjustment also requires a certain amount of space, but at most one-third of the original volume needs to be increased.

The technical solution adopted by the present invention to solve its technical problems is: it fixes the "insulating piston sleeve" with electrodes embedded in it in a shell, and the "insulated piston" embedded with electrodes passes through the silicone ring and the inner wall of the "insulated piston sleeve". Closely fit, fix an adjusting screw at the center of the outside of the "insulating piston", set an adjusting nut on the shell corresponding to the axis of the adjusting screw, set up a water inlet and a water outlet on the "insulating piston sleeve", the two stages of the power supply are respectively connected to the The two electrodes are sealed and connected, which forms the "core device" of the multi-functional faucet. When corresponding to different hardness water quality, you only need to turn the adjusting nut to adjust the distance between the electrodes to get the required power. In order to prevent the leakage of strong current, the water inlet and outlet should be Adding a "water resistance attenuation type" anti-electricity wall, due to the large water hardness span makes the power change range is large, in order to prevent the "overcurrent" danger caused by misoperation, a current limiting switch can be added on the circuit, the beneficial effect of the present invention Yes, while maintaining the long life of the electrodes, the required power can be obtained by adjusting the distance between the electrodes in a timely manner. It is suitable for heating, magnetizing or sterilizing tap water with large-span changes in water hardness.
