Description
Technical Field
The utility model belongs to the technical field of ultraviolet sterilization, and particularly relates to a detector for ultraviolet sterilization.
Background
In recent years, the advantage of using ultraviolet rays to kill aquatic infectious pathogens has been widely confirmed. The ultraviolet sterilization technology is widely applied to industries such as pure water preparation, sewage treatment and the like in the industries such as food, medicine, chemical industry, electronics and the like. The ultraviolet sterilizer can sterilize fresh water, seawater, sewage and various waste water containing high-risk pathogens. Therefore, the ultraviolet sterilizer belongs to a water sterilizing product with high sterilizing efficiency, wide application field and low running cost.
In the use process of the ultraviolet sterilizer, the ultraviolet lamp tube has a certain service life, and the radiation intensity can be gradually weakened due to the increase of the use time, so that the ultraviolet sterilizer cannot perform the sterilization and disinfection function, and the ultraviolet sterilizer is subjected to radiation illuminance monitoring by the ultraviolet sterilization detector in a matched manner so as to ensure the ultraviolet sterilization effect. The ultraviolet sterilization detector is mainly an integrated design of sealing glue, and specifically comprises: placing an ultraviolet sensing device (comprising an ultraviolet sensor and a signal processing circuit board) in a shell with a cavity, and leading out a power supply line and a signal line; in addition, the shells of the ultraviolet sterilization detectors with different specifications are provided with threads with different specifications. When the ultraviolet sensing device is fixed, the ultraviolet sensor and the signal processing circuit board are fixed in the cavity by filling epoxy resin curing glue into the cavity of the shell, and the signal processing circuit board and the ultraviolet sensor are waterproof.
However, in the actual use process, due to the integrated sealing design adopted by the ultraviolet sterilization detector, when the ultraviolet sensor, the signal processing circuit board and other components fail, the whole ultraviolet sterilization detector must be replaced.
Disclosure of Invention
The utility model aims to provide a detector for ultraviolet sterilization, which solves the problem that when part of components of the current detector for ultraviolet sterilization are damaged, the whole detector for ultraviolet sterilization needs to be replaced.
The ultraviolet sterilization detector comprises a shell and a barrel, wherein one ends of the shell are open, the barrel is positioned in the shell, and the open ends of the shell and the barrel are positioned on the same side; an ultraviolet sensing device is arranged in the cylinder, and a light converging hole for ultraviolet light to pass through is formed in one end of the cylinder, which is far away from the opening; the opening end of the shell is provided with a pressure head for plugging the cylinder; an incident hole for passing ultraviolet light of the ultraviolet sterilizer is formed in one end of the shell, which is far away from the opening; the lens and the annular first waterproof gasket are sequentially arranged in the shell from bottom to top, and the first waterproof gasket is in contact with the lower surface of the barrel.
The working principle of the scheme and the beneficial effects thereof are that: before use, one end of the shell far away from the opening is fixed on the ultraviolet sterilizer. When the ultraviolet sterilizer is used, ultraviolet light emitted by the ultraviolet lamp tube of the ultraviolet sterilizer is converged on the ultraviolet sensing device through the inlet hole, the lens and the light converging hole, and the ultraviolet sensing device detects the ultraviolet intensity of the ultraviolet sterilizer. When the ultraviolet sensor or the ultraviolet sensor and the signal processing circuit board of the ultraviolet sensor are in failure, the pressure head is only required to be taken down, and the cylinder body and the ultraviolet sensor in the cylinder body are replaced. When the shell or the lens is damaged, only the corresponding damaged part needs to be replaced.
Further, an external thread is arranged on the outer wall of the shell, and the external thread is positioned at one end of the shell far away from the opening; the external thread is connected with a fixing ring through threads. In the prior art, as different external threads are arranged outside the shell of different ultraviolet sterilization detectors, the ultraviolet sterilization detectors need to process internal threads used for fixing the detectors according to the external threads, and the processing cost is high. According to the scheme, through the arrangement of the fixing ring, the fixing ring is only required to be arranged on the ultraviolet sterilizer; thus, the detector is more convenient to install.
Further, annular spacing boss has integrated into one piece on the outer wall of casing, waterproof silica gel circle has been cup jointed on the casing, waterproof silica gel circle is located between spacing boss and the external screw thread. Through the setting of waterproof silica gel circle, can further improve the waterproof performance of sealing of casing and solid fixed ring junction.
Further, an annular second waterproof gasket is arranged in the shell and is in contact with the lower surface of the lens. Through the setting of second waterproof gasket, can further strengthen waterproof performance.
Further, the lens is a quartz glass lens, a nylon plastic lens or a silica gel lens. Quartz glass lenses, nylon plastic lenses and silica gel lenses are transparent to short wave ultraviolet light.
Further, a chamfer is arranged on the side wall of the inlet hole of the shell, and the inclination of the chamfer is consistent with the incident angle of the ultraviolet sensing device. The inclination of the chamfer is consistent with the incident angle of the ultraviolet sensing device, so that the incident quantity of ultraviolet light can be improved, and a better detection effect is achieved.
