Description

Ultraviolet light sterilization device

The invention relates to a sterilizing device, in particular to an ultraviolet ray sterilizing device, which can continuously change the irradiation angle when the ultraviolet light is irradiated, reduce the irradiation dead angle, and improve the sterilization rate.

It is well known that many infections and diseases are caused by microorganisms. The existing two microbial treatment procedures are disinfection and sterilization. Disinfection refers to the process of reducing the amount of microorganisms in a sample, and sterilization is the elimination of the order of microorganisms in a sample. However, considering the cost, time and risk of regional sterilization methods such as extremely high/low temperature sterilization, ionizing radiation, antimicrobial chemicals, etc., in most places, such as hospitals, physician offices or other medical sites, usually only Disinfection, sterilization has little effect. For example, medical facilities such as hospitals or clinics often use disinfectants to wipe the operating room to contact the surface or floor of the patient's items for "disinfection" rather than "sterilization."

The disadvantage of the disinfection procedure is that the disinfectant does not guarantee that all microorganisms can be killed, and only the amount of microorganisms can be reduced. In this way, the microorganisms that survive the disinfection process not only cause potential dangers in the operating room such as the medical field, but the surviving microorganisms after the disinfectant disinfection will multiply or divide the offspring that can survive the disinfection process, in other words. Microbial genes are genetically resistant to disinfection, and new disinfectants or disinfection techniques must be used to inhibit new strains.

On the other hand, sterilization destroys all microorganisms in an area or on the surface, for example, the high heat generated by high-temperature and high-pressure steam in a pressure cooker to sterilize the equipment in the pressure cooker, and another known sterilization method. It is a kind of sterilizing method that is effective for destroying microorganisms or reducing the number of microorganisms on the surface of air, water or objects, and its sterilization effect must be based on the intensity of ultraviolet rays and the time of irradiation, more precisely, nowadays It has been found that the proliferation/split of bacteria, bacterial spores, fungal spores and viruses becomes sluggish under ultraviolet light, because ultraviolet light with a wavelength of 185 nm and 265 nm in ultraviolet light is deoxyribonucleic acid (DNA). Absorption, which causes the two thymines that are phase-bonded in the DNA to be deaminated and form a TT bond (ie, a genetic mutation), which prevents the DNA from replicating and rendering the microorganism unable to multiply.

However, although most experiments have confirmed that ultraviolet light can effectively sterilize the environment, today's hospitals use ultraviolet ray sterilization methods to place ultraviolet light tubes on the ceiling of the clinic, and select personnel in a fixed-time clearance room. The ultraviolet light tube is turned on for sterilization, but due to the arrangement of various items in the medical treatment room, the ultraviolet light tube on the ceiling is irradiated with a dead angle, so that the bacteria that irradiate the dead angle are not killed, and the unkilled ones are not killed. Bacterial reproduction progeny may still gradually increase the resistance to ultraviolet light, resulting in a reduction in the effect of ultraviolet light sterilization; in addition, because excessive ultraviolet light will also affect the human genome and cause lesions, therefore, the number of ultraviolet light The method of sterilizing the tube cannot be used in an open space such as a waiting room where people often enter and exit, so that an open space such as a waiting room in a hospital is likely to become a dead space for bacterial growth.

In view of the above technical defects in sterilizing a fixed ultraviolet lamp tube, the main object of the present invention is to provide an ultraviolet light sterilizing device which can reduce the dead angle of ultraviolet light irradiation and improve the sterilization rate to the environment.

The main technical means for achieving the above purpose is that the ultraviolet sterilizing device comprises: a cover; at least one movable arm is disposed at a periphery of the cover; at least one ultraviolet light tube is set to the at least a controller is disposed on the cover and electrically connected to the at least one ultraviolet tube and the at least one movable arm to illuminate the ultraviolet lamp and control the movable arm to move.

Since the plurality of movable arms of the present invention are pivotally moved, the irradiation angle of the ultraviolet light after the ultraviolet lamp is fixed on the movable arm is continuously changed, thereby reducing the ultraviolet light irradiation dead angle and improving the sterilization rate.

Moreover, another object of the present invention is to provide an ultraviolet light sterilizing device having an air filter function, and can be used for an open space where people often enter and exit, and further provided at least one closable cover on the cover. a curtain, and an air passage is formed inside, the air passage forms an air inlet and an air outlet on the outer surface of the cover; when the shade is opened, the at least one ultraviolet light tube is exposed to the cover, and when the blind is closed Having the at least one ultraviolet tube illuminate the air passage; and providing a fan in the air passage of the cover, the fan being electrically connected to the control air to draw air from the air inlet when the curtain is closed After blowing through the air passage of the ultraviolet lamp, it is blown out by the air outlet.

Thus, the present invention allows the controller to drive the plurality of shades to close the cover and drive the fan to operate, so that the ultraviolet light emitted by the ultraviolet light tube only illuminates the air passage in the cover body, and the air is driven by the fan. The air inlet is inhaled, and the air passage is blown out by the ultraviolet light and then blown out from the air outlet to sterilize the surrounding air, so that the ultraviolet light does not affect the human body, and can be used in an open space such as a waiting room where people often enter and exit.
