DETAILED DESCRIPTION

[0032] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0033] Referring to Figures 1-4 , a kind of sterilization device, including lamp tube 100, ultraviolet lamp, spiral scale removal brush 300 and rotating shaft 400, lamp tube 100 is quartz lamp tube, the water inlet end and the water outlet end of two ends of lamp tube 100 respectively, rotating shaft 400 is installed in lamp tube 100 along the axis of lamp tube 100, spiral scale removal brush 300 is installed on rotating shaft 400, spiral scale removal brush 300 has spiral brush sheet 310, the outer end portion in the radial direction of spiral brush sheet 310 is soft glue material, and it is abutted on the inner wall of lamp tube 100, spiral scale removal brush 300 can be driven to rotate by water flow, ultraviolet lamp is located at the outside of lamp tube 100, the position of ultraviolet lamp corresponds with the position of spiral scale removal brush 300, the direction of illumination of ultraviolet lamp is towards spiral scale removal brush 300. Water inlet end of lamp tube 100 is water inlet, when water body flows, ultraviolet lamp has passed through power on, is in sterilization state. Water body flow drives spiral scale removal brush 300 to rotate, because spiral spiral brush sheet 310 blocks the flow of water, water flow is directly axially impacted spiral brush sheet 310, spiral brush sheet 310 will be driven by the resultant force of water flow rotation, to drive spiral scale removal brush 300 to rotate.

[0034] In some embodiments of the utility model, still include memory alloy spring 500 and reset spring 600, spiral scale brush 300 is sleeved on the pivot 400, spiral scale brush 300 can move along the pivot 400 axially, one end of pivot 400 is equipped with first limit flange 410, and the other end is equipped with second limit flange 420, memory alloy spring 500 and reset spring 600 are sleeved on the pivot 400, and memory alloy spring 500 and reset spring 600 are located at both ends of spiral scale brush 300 respectively, wherein memory alloy spring 500 is abutted between first limit flange 410 and spiral scale brush 300, and reset spring 600 is abutted between second limit flange 420 and spiral scale brush 300. Cold water is not easy to scale and breed covering, and if there is cold water flow, it is easy to scrape off. But when the water flow is static, especially when hot water is stored in the pipeline, the water temperature is still relatively high, the molecular movement is relatively fast, and the water hardness is high, scale will be attached to the pipe wall. If not used for a long time, scale will be obvious, and the next time the water flow is difficult to easily scrape off the scale. In order to solve the problem that hot water is easy to scale when static, the utility model sets memory alloy spring 500 and reset spring 600 at both ends of pivot 400 respectively, when the temperature of incoming water is less than the deformation temperature of memory alloy spring 500, that is, cold water, memory alloy spring 500 is in compression state, water flow directly impacts spiral scale brush 300 to rotate and scrape off the adhering matter of the pipe wall. When the temperature of incoming water is greater than the deformation temperature of memory alloy spring 500, that is, hot water, memory alloy spring 500 deforms, reset spring 600 is compressed, memory alloy spring 500 pushes spiral scale brush 300 to move axially, water flow directly impacts spiral scale brush 300 to rotate and scrape off the adhering matter of the inner wall of lamp tube 100. When hot water flow is static, the water temperature will slowly decrease, the deformation stiffness of memory alloy spring 500 will slowly become soft, and reset spring 600 will push spiral scale brush 300 to move axially and slowly reset, which will scrape the inner wall of lamp tube 100, until the temperature decreases to normal temperature, and the normal temperature water is not easy to adhere to the pipe wall, which prevents the problem of scale formation when high-temperature water is static.
