Description

Technical Field

[0001] The utility model relates to the field of disinfection equipment, in particular to a segmented ultraviolet sterilization and disinfection machine with a reflective function. Background Art

[0002] UV is a general term for ultraviolet rays: the ultraviolet wavelength range is 100nm ~ 420nm (nm is nanometer unit), and UVC is ultraviolet light with a wavelength of 200 ~ 275nm (central wavelength 254nm), and only the UVC wavelength band has the function of sterilization. The UVC germicidal lamp and UV germicidal lamp commonly referred to refer to the same product.

[0003] At present, the main germicidal lamps are UVC mercury lamp tubes as light sources and UVC-LED lamp beads as light sources. The difference between the two is:

[0004] 1: The characteristics of UVC mercury lamp light source are: low manufacturing cost, mercury-containing and not environmentally friendly, wide wavelength, royal oxygen will be produced when the wavelength reaches 180, the ultraviolet energy is relatively weak, and the sterilization time is long.

[0005] 2. The characteristics of UVC-LED lamp beads are: the wavelength is concentrated in 260-280nm, the ultraviolet energy is strong, and the sterilization is fast. Currently, there are products on the market that can achieve a sterilization rate of 99.99% in 59 seconds. LED-UVC can be easily designed with different shapes according to different application scenarios, making sterilization and disinfection in our lives more convenient and portable. In addition, LED is energy-saving and environmentally friendly. With the improvement of technology and large-scale application, it has been widely used in our lives.

[0006] Ultraviolet rays can be divided into: UVA band (wavelength: 320 ~ 400nm), UVB band (wavelength 275 ~ 320nm), UVC band (200 ~ 275nm), UVD band (100 ~ 200nm). Lamps with these wavelengths are all ultraviolet lamps!

[0007] Ultraviolet germicidal lamps can be divided into: ozone (UVC peak at 185nm) and non-ozone (UVC peak at 254nm). The 254nm wavelength ultraviolet rays emitted by non-ozone ultraviolet germicidal lamps kill bacteria by irradiating, destroying or changing the DNA (deoxyribonucleic acid) structure of microorganisms, causing the bacteria to die immediately or unable to reproduce, thus achieving the purpose of sterilization. The 185nm wavelength ultraviolet rays emitted by ozone ultraviolet germicidal lamps convert oxygen in the air into ozone (ozone has strong oxidizing properties and can effectively kill bacteria).

[0008] The main differences between germicidal lamps are:

[0009] 1. Different properties: 1. Ultraviolet germicidal lamp: a low-pressure mercury lamp; 2. Purple lamp: a device that can emit ultraviolet rays.

[0010] 2. Different functions: 1. Ultraviolet germicidal lamp: mainly used for sterilization and disinfection of water and air. The ultraviolet rays (UVC) generated by the ultraviolet germicidal lamp irradiate the water flow. When the bacteria, viruses, algae and other organisms in the water are irradiated with a certain dose of UVC (wavelength 254nm), the DNA and RNA structures of their cells are destroyed, the cells cannot regenerate, and the bacteria and viruses lose the ability to replicate themselves, thereby achieving the purpose of sterilization and disinfection. 2. Purple light: ultraviolet disinfection, ultraviolet medical treatment, ultraviolet detection and anti-counterfeiting, ultraviolet sterilization, ultraviolet curing, ultraviolet background light.

[0011] 3. Different lamp colors: 1. Ultraviolet germicidal lamp: The lamp tube is transparent. 2. Purple lamp: The lamp tube is purple.

[0012] Currently, ultraviolet sterilization and disinfection machines on the market generally use ultraviolet rays to directly irradiate the entire channel space for sterilization and disinfection. The sterilization time of such sterilization and disinfection machines is long and the effect is average. Utility Model Content

[0013] In order to solve the problem that the sterilization time of the sterilization disinfection machine in the prior art is long and the effect is average, the purpose of the utility model is to provide a segmented ultraviolet sterilization disinfection machine with a reflective function, which can reduce the sterilization time and increase the sterilization effect.

[0014] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a segmented ultraviolet sterilization and disinfection machine with a reflective function, comprising a shell, on which an air inlet and an air outlet are arranged, a plurality of reflective plates are fixed in the shell, the plurality of reflective plates are arranged at intervals, and the reflective plates are arranged between the air inlet and the air outlet; an ultraviolet lamp for emitting light is arranged between adjacent reflective plates; and a fan is installed in the shell.

[0015] Preferably, a filter screen for filtering air is provided in the housing.

[0016] Preferably, the filter is arranged at the air inlet of the shell.

[0017] Preferably, a photocatalyst plate is arranged in the housing.

[0018] Preferably, the photocatalyst plate is arranged at the air outlet of the housing.

[0019] Preferably, the catalyst plate and the fan are arranged on both sides of the reflective plate, and ultraviolet rays can be emitted from two adjacent reflective plates and irradiate the photocatalyst plate and the fan.

[0020] Preferably, the ultraviolet lamp includes at least one UVC-LED germicidal lamp bead, and the UVC-LED germicidal lamp bead is arranged on the reflective plate.

[0021] Preferably, the ultraviolet lamp comprises a UVC germicidal lamp tube, through holes are provided on the reflective plates, and the UVC germicidal lamp tube passes through the through holes on the plurality of reflective plates.

[0022] Preferably, the fan is arranged between the reflector and the air inlet.

[0023] Preferably, the air inlet is located at the bottom of the shell, and the air outlet is located at the top of the shell.

[0024] The beneficial effects of the technical solution of the utility model are as follows: the reflector has the effect of ultraviolet reflection enhancing refractive index and segmented precise sterilization, and two adjacent reflectors can refract and reflect light to each other, further improving the sterilization effect; a plurality of reflectors arranged at intervals separate the light source of the ultraviolet lamp and the air to be sterilized into multiple sections, and the air flows between the plurality of reflectors, thereby improving the air disinfection efficiency; the ultraviolet light source is located between two adjacent reflectors, thereby enhancing the disinfection of the disinfection machine; the ultraviolet light can be emitted from between two adjacent reflectors, thereby irradiating the inner cavity of the shell, thereby increasing the sterilization range of the disinfection machine; the ultraviolet lamp is arranged on a plurality of reflectors, thereby forming a strong sterilization area between two adjacent reflectors, thereby reducing the sterilization time and increasing the sterilization effect.
