Plasma tube with built-in resistor

Abstract

The invention discloses a plasma tube with a built-in resistor. The plasma tube is characterized in that an electric heating wire is wound on the outer side of a heating ceramic tube, and the outer side of the electric heating wire and the outer side of the heating ceramic tube are wrapped with a thermal shrinkage insulating bushing through a thermal shrinkage technology to form a resistor assembly; a tungsten filament is wound on the spiral groove of an external threaded ceramic tube, and a stainless steel cylinder which is curled into a cylinder shape is attached to the inner wall of the external threaded ceramic tube to form an ion tube assembly; and the resistor assembly is arranged in the ion tube assembly to form the plasma tube with the built-in resistor. According to the invention, during working, the plasma tube is matched with a direct-current power supply and a high-voltage oscillation circuit for use; the heat energy of the resistor assembly removes water mist on the surface of the ion tube assembly so as to greatly reduce the oscillation starting load of the high-voltage oscillation circuit, and when the medium discharges, the heat energy emitted by the resistor assembly plays a role in promoting the discharge of the medium; and the plasma tube has the advantages of being simple in structure, convenient to use, wide in application range and high in working efficiency.

Description

technical field [0001] The invention relates to the field of plasma technology, in particular to a plasma tube with built-in resistance. Background technique [0002] With the improvement of people's living standards, the degree of attention to hygiene and health is also increasing, and products such as air humidifiers, negative oxygen ion generators and air purifiers for home use have also emerged as the times require. These products are related to the rapid development of plasma technology. The development is inseparable. Most of the plasma tubes in the prior art are a form of dielectric discharge formed by the combination of inductance and capacitance. The problem is that when encountering an environment with high humidity and low temperature, especially central air-conditioning refrigeration When the air outlet is under normal conditions, the humidity of the air conditioner is relatively high, and the water molecules in the air and the air conditioner will be adsorbed to...

[0002] With the improvement of people's living standards, the degree of attention to hygiene and health is also increasing, and products such as air humidifiers, negative oxygen ion generators and air purifiers for home use have also emerged as the times require. These products are related to the rapid development of plasma technology. The development is inseparable. Most of the plasma tubes in the prior art are a form of dielectric discharge formed by the combination of inductance and capacitance. The problem is that when encountering an environment with high humidity and low temperature, especially central air-conditioning refrigeration When the air outlet is under normal conditions, the humidity of the air conditioner is relatively high, and the water molecules in the air and the air conditioner will be adsorbed to the surface of the ceramic tube and the quartz glass tube, causing the load current to increase, resulting in the failure of the high-voltage oscillating line to vibrate, and the performance of the product is reduced. How to solve the problem of how to solve the normal operation of the plasma tube in the environment of high humidity and low temperature is an urgent problem
