Description

 Technical field

 The present invention relates to a generator for producing a disinfectant in an electrolytic or ionizing manner, and more particularly to a disinfectant generator controlled by a 'constant current source'.

 Background technique

 Since the development of generators for the production of disinfectants by electrolytic or ionization methods in the 1980s, to date, most of the processing power of disinfectant generators has been controlled by constant voltage sources, and individual generators have not even controlled the constant voltage sources. After decades of practice, it has been found that the disinfectant generator controlled by a constant pressure source has serious defects;

 During electrolyte electrolysis or ionization, the temperature of the solution will rise continuously due to the large amount of heat released by the chemical reaction. As the temperature increases, so does the processing current. With the extension of the processing time, the current will continue to be maintained at a higher value, which will cause the equipment to overload the operation. In the long term, this will damage the equipment, reduce the service life of the equipment, and increase costs. '

 2. The disinfectant generator controlled by a constant voltage source, during the processing, due to changes in the environment or improper human operation, the processing current will also change, making the entire device unstable.

 3. When the electrolysis or ionization device is unchanged, the effective concentration of the disinfectant, that is, the output of the disinfectant mainly depends on the processing current. The larger the processing current, the higher the concentration of the disinfectant. Therefore, when the processing current changes, the concentration of the disinfectant changes, and the effective concentration (yield) of the disinfectant cannot be guaranteed to be constant. Since the emergence of a disinfectant generator controlled by a constant pressure source in the 1980s, there has been a misconception that the higher the concentration of the disinfectant, the better. In fact, this is wrong. The higher the concentration of the disinfectant, the better, but the more stable it is to keep within the qualified concentration range.

Summary of the invention

 In view of the foregoing, an object of the present invention is to provide a disinfectant generator controlled by a constant current source. In order to achieve the above object, the present invention adopts the following design schemes: A constant-output disinfectant generator, which is composed of a constant-current power supply and an electrolytic device. It is connected to the anode of the electrolytic device, and the negative electrode of the constant current power supply is connected to the cathode of the electrolytic device.

Since the present invention uses a constant current source to control the electrolysis or ionization process of the disinfectant generator, the constant processing current is guaranteed, thereby effectively solving the processing current change caused by environmental changes or human factors. Changes in the concentration of disinfectants; effectively overcomes the problem that as the temperature of the electrolyte rises during processing, the processing current also increases, so that the equipment will not run overload and prolongs the service life of the equipment; more importantly One point is: The present invention effectively ensures that the effective concentration of the disinfectant produced in each batch, that is, the yield is constant.
