Compared with the prior art, the utility model has the following characteristics and beneficial effects:

The utility model overcomes the shortcomings of short service life, unstable sterilizing effect and low efficiency of the ultraviolet lamp of the traditional disinfection and sterilization device, and solves the technical problems of improving the sterilizing efficiency and prolonging the service life of the ultraviolet lamp.

The utility model adopts a microwave electrodeless ultraviolet lamp tube, which excites the inert gas filled in the lamp under the action of microwaves to emit ultraviolet light. Since the microwave electrodeless ultraviolet lamp tube has no electrodes, the problem of the lamp tube turning black is completely solved, and the service life of the ultraviolet lamp is extended. Long service life; at the same time, the lamp can also emit vacuum ultraviolet light with higher energy, which can effectively kill pathogenic microorganisms in water under the condition of the presence of titanium dioxide catalyst, and the disinfection and sterilization effect is more significant and the efficiency is also higher.

The utility model considers various factors. Firstly, the microwave electrodeless ultraviolet lamp tube is set in the quartz sleeve, which is protected by the quartz sleeve and is not easy to be damaged. At the same time, the water temperature is relatively high due to the heating of the microwave electrodeless ultraviolet lamp tube. The microwave electrodeless ultraviolet lamp tube is set in the quartz sleeve to avoid the phenomenon of the microwave electrodeless ultraviolet lamp tube being heated and contracted by water; secondly, the microwave electrodeless ultraviolet lamp tube is rotatably installed in the shell, and the tail end protrudes The body is connected with a microwave exciter, and the microwave exciter is used to excite the electrodeless ultraviolet lamp to emit light for microbial sterilization; again, a layer of nano-titanium dioxide coating is coated on the inner wall of the housing, and the ultraviolet light undergoes a photocatalytic reaction on the surface of the nano-titanium dioxide coating, producing Hydroxyl free radicals with high oxidation activity can fully stimulate the bactericidal ability of the ultraviolet lamp to ensure the bactericidal effect; in addition, the microwave electrodeless ultraviolet lamp tube is designed in a spiral shape, so that when the water flow enters from the bottom of the shell and passes through the gap between the ultraviolet lamp and the shell from In the process of flowing out from the top of the shell, it can be fully mixed and produce a strong turbulent flow to improve the disinfection efficiency; finally, the spiral design of the UV lamp also increases the contact time and contact area between the UV lamp and water, fully prolonging the disinfection effect. The disinfection and sterilization time of the water flow improves the sterilization efficiency.

The utility model can be widely used in disinfection of water tanks.
