Description

Technical Field

[0001] This utility model relates to the field of ultraviolet disinfection lamps, and more particularly to an ultraviolet disinfection lamp with a delayed start time. Background Technology

[0002] Ultraviolet (UV) disinfection lamps are lighting devices that utilize the bactericidal effect of ultraviolet light for disinfection and sterilization.

[0003] Most existing ultraviolet disinfection lamps are turned on as needed, but sometimes disinfection is required after experiments. Waiting for the disinfection to complete before turning off the lamp wastes time. If it is not turned off, it is inconvenient to return to the laboratory to turn off the lamp after disinfection.

[0004] Therefore, since most existing ultraviolet disinfection lamps are turned on as needed, which is inconvenient to use, a delayed-on ultraviolet disinfection lamp can be designed to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing ultraviolet disinfection lamps, which are mostly turned on as needed but sometimes require disinfection after experiments, it is necessary to turn them off after disinfection, which is inconvenient. Alternatively, waiting for disinfection to complete before turning off the lamp would waste the waiting time.

[0006] The technical solution of this utility model is as follows: a delayed-on ultraviolet disinfection lamp, including a four-corner base and a lamp body assembly. The upper end of the four-corner base is provided with a lamp body assembly for delayed switching. The lamp body assembly includes a hollow column, inside which is a cylinder. The upper end of the cylinder is provided with a protective cover, inside which is a rotating motor. The upper end of the rotating motor is drivenly connected to a rotating shaft. A U-shaped plate is provided on the rotating shaft. A rotating motor is provided on one side of the U-shaped plate. A rotating shaft is drivenly connected to the rotating motor. A disinfection lamp body is provided on the rotating shaft. The upper end of the disinfection lamp body is provided with a switch button. An electric slide rail is provided on the U-shaped plate. A movable slider is slidably connected to the electric slide rail. The upper end of the movable slider is provided with a telescopic rod. The front end of the telescopic rod is provided with a connecting pressing plate. The upper end of the connecting pressing plate is provided with a timer.

[0007] Preferably, the height can be adjusted according to the height requirement by setting a height adjustment. A rotating connection is set at the upper end of the height adjustment, which can rotate 360 ​​degrees. A slide rail is set on the rotating device, and a movable pressing structure is set on the slide rail. The pressing structure is controlled by a timer. The timer can be set to control the pressing structure to move on the slide rail and press the switch of the ultraviolet lamp to turn it on and off.

[0008] Preferably, the hollow column is hollow, the cylinder is located inside the hollow column, the protective cover is hollow, and the rotating motor is located inside the hollow cover.

[0009] Preferably, the U-shaped plate is U-shaped, and the electric slide rail is set on the U-shaped plate.

[0010] Preferably, the disinfection lamp body and the switch button are set as a whole, and the disinfection lamp body is fixed on the rotating shaft.

[0011] Preferably, the connecting press plate is protruding and fixedly connected to the telescopic rod, and the timer is electrically connected to the electric slide rail.

[0012] Preferably, the four-corner base is designed with protruding corners and has arc-shaped slots on all four sides.

[0013] Preferably, the lower end of the four-corner base is provided with casters, the lower end of the center of the four-corner base is provided with a support foot, and the four-corner base is located at the lower end of the hollow column.

[0014] The beneficial effects of this utility model are:

[0015] 1. By incorporating a hollow column protective cylinder, the cylinder's extension and retraction allow for automatic height adjustment. Simultaneously, a protective cover protects the rotating motor. When the motor starts, it drives the rotating shaft and the U-shaped plate connected to it, enabling directional adjustment. The rotating motor also drives the rotating shaft and the disinfection lamp body, allowing for 360-degree rotation adjustment. For delayed switch operation, a timer is set. Upon reaching the designated time, a sliding block moves along the electric slide rail, shifting the telescopic rod and connecting pressure plate. When the slider reaches the top of the switch button, the telescopic rod extends or retracts, adjusting the height of the connecting pressure plate and pressing the switch button to turn the disinfection lamp on and off. This design overcomes the shortcomings of existing UV disinfection lamps, which are typically turned on immediately after use. However, sometimes disinfection is required after experiments, and leaving the lamp on until after disinfection is inconvenient. Waiting for the lamp to finish before turning it off wastes time.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Among the currently discovered feasible technologies, ultraviolet (UV) disinfection lamps are lighting devices that utilize the bactericidal effect of ultraviolet light for disinfection and sterilization. The following is a detailed description:

[0023] principle

[0024] The working principle of ultraviolet disinfection lamps is based on the gas discharge theory. Charged particles in the dry gas form an electric current, which generates light through gas discharge.

[0025] When microorganisms are exposed to ultraviolet radiation, their deoxyribonucleic acid (DNA) absorbs the energy of ultraviolet photons, causing the formation of dimers between adjacent thymine groups on the same strand of the DNA molecule. This interferes with the double helix structure of DNA, prevents the synthesis of RNA primers, and thus interrupts the replication and transcription functions of DNA.

[0026] Ultraviolet radiation can also generate free radicals and trigger photoionization processes. The generation of these free radicals interferes with the biochemical processes of microorganisms, making them unable to replicate and reproduce.

[0027] structure

[0028] It mainly consists of lamp tubes, ballasts, starters, and lamp holders:

[0029] Lamp tube: It is the main component of the ultraviolet lamp circuit. It consists of lamp head, filament, glass tube and other parts. The tube contains a small amount of argon gas and a thin amount of mercury vapor. Its material is generally quartz glass and the inner wall is not coated with phosphor.

[0030] Ballast: Also known as a current limiter, it consists of an iron core and an inductor coil. Its main function is to generate high voltage and limit the current passing through the lamp tube, so that the ultraviolet lamp can light up and work. Its specifications must be matched with the lamp tube power.

[0031] Starter: It consists of a neon bulb, a small capacitor, an insulating base and a housing. The neon bulb inside can automatically connect and disconnect the circuit. The small capacitor connected in parallel with the neon bulb has two main functions: first, to form an LC oscillation circuit with the ballast coil to extend the warm-up time and maintain the pulse electromotive force; and second, to absorb noise that can interfere with electronic devices such as radios and televisions.

[0032] Lamp holder: Used to fix lamp tubes and connect circuits. Common lamp holders are of two types: plug-in and open type. Their specifications must be matched with the lamp holder on the lamp tube.

[0033] Classification

[0034] Based on the different metal or compound vapors filled in the ultraviolet lamp tubes, or based on the different lamp tube materials, ozone levels, and electrodes, they can be roughly divided into the following seven categories:

[0035] Medium and high pressure mercury lamps: They have high ultraviolet output intensity and can be used for large-area, high-intensity disinfection needs, but their energy consumption is relatively high and they need to be equipped with corresponding ballasts and starting devices.

[0036] High-intensity ultraviolet disinfection lamps: These lamps produce high-intensity ultraviolet light, resulting in significant sterilization effects. They are suitable for places with high disinfection requirements, such as hospital operating rooms and laboratories, but they are relatively expensive.

[0037] Low-ozone ultraviolet lamps: During the generation of ultraviolet light, less ozone is produced, which can reduce the adverse effects of ozone on the human body and the environment, and is suitable for air disinfection in human environments.

[0038] High-ozone ultraviolet lamps: can produce more ozone. Ozone has strong oxidizing properties, which can enhance the disinfection effect. They are suitable for air disinfection and object surface disinfection in unmanned environments. However, after disinfection, ventilation is required for a period of time, and personnel can only enter after the ozone has decomposed.

[0039] Cold cathode ultraviolet lamps have advantages such as simple structure, long life, no need for preheating, and can start up quickly. They are suitable for occasions with frequent switching, such as elevators and bathrooms, but the ultraviolet output intensity is relatively low.

[0040] Hot cathode ultraviolet lamps: They have high ultraviolet output intensity and good sterilization effect, but they need to be preheated for a period of time to reach a stable working state, and their lifespan is relatively short. They are suitable for places with high requirements for disinfection effect and low usage frequency.

[0041] H-type ultraviolet lamp: This is a new type of ultraviolet lamp with advantages such as high efficiency, energy saving, and long life. Its ultraviolet output intensity and sterilization effect are superior to traditional ultraviolet lamps, and it is one of the future development directions of ultraviolet disinfection lamps.

[0042] Features

[0043] Broad bactericidal spectrum: It can kill various microorganisms, including vegetative bacteria, bacterial spores, tubercle bacilli, fungi, viruses, and rickettsiae.

[0044] Weak penetrating power: Ultraviolet radiation is electromagnetic radiation with extremely weak penetrating power. Most substances cannot penetrate it. In the air, it can be affected by dust particles and humidity. In liquids, its penetrating power also decreases with increasing depth.

[0045] The bactericidal effect is related to the irradiation dose: the bactericidal effect directly depends on the irradiation dose, which is equal to the product of the ultraviolet intensity and the irradiation time.

[0046] Precautions for use

[0047] Choose the right disinfection lamp: Select a disinfection lamp with appropriate power and size according to the size of the space to be disinfected and the frequency of disinfection.

[0048] Proper installation: Install the disinfection lamp in a suitable location, ensuring that the ultraviolet light can reach the area that needs to be disinfected. The installation height is usually 1-1.5 meters from the ground and 1-2 meters from the area to be disinfected.

[0049] Avoid human contact: Ultraviolet rays are harmful to the human body. When disinfecting, ensure that there are no people or animals in the disinfection area. People should also avoid looking directly at the ultraviolet light source. If necessary, wear protective glasses.

[0050] Control the disinfection time: Generally, it is necessary to irradiate for more than 30 minutes to achieve the disinfection effect, but it should not be irradiated for a long time to avoid damage to the items or causing safety hazards.

[0051] Note environmental factors: The disinfection environment should be kept clean and free of dust, debris, etc., to ensure the penetration of ultraviolet rays and the sterilization effect; when used for air disinfection, the relative humidity of the disinfection environment should be below 80%, and the temperature should be between 20℃ and 40℃.

[0052] Regular inspection and maintenance: The intensity of ultraviolet lamp irradiation will gradually decrease, so it needs to be monitored regularly. When the intensity is lower than the specified value, the lamp tube should be replaced in time. In addition, the lamp tube should be cleaned regularly to avoid affecting the transmittance of ultraviolet rays.

[0053] A delayed-time ultraviolet disinfection lamp is a disinfection device that adds a delayed-time function to a regular ultraviolet disinfection lamp.

[0054] Working principle:

[0055] The working principle of delayed ultraviolet disinfection lamps is the same as that of ordinary ultraviolet disinfection lamps. They both use the bactericidal effect of ultraviolet light to destroy the DNA structure of microorganisms, thereby achieving the effect of disinfection and sterilization. The delay function is realized through the control circuit. Users can set the start-up delay time and working duration of the disinfection lamp as needed.

[0056] advantage

[0057] High safety: The delayed start function provides users with enough time to evacuate the disinfection site, avoiding direct damage to human skin and eyes from ultraviolet rays, and effectively reducing safety risks during use.

[0058] Easy to use: The delay time and disinfection duration can be flexibly set according to different disinfection scenarios and needs, meeting the personalized disinfection needs of users, and eliminating the need for personnel to wait on-site for the disinfection lamp to turn on or off.

[0059] Wide range of applications: Suitable for various places that require ultraviolet disinfection, such as hospitals, laboratories, food processing plants, and homes. For places where personnel cannot be evacuated in time, such as operating rooms and sterile workshops, the time delay function is particularly important.

[0060] Application scenarios

[0061] For home use: It can be used to disinfect the air and surfaces of objects in various rooms such as bedrooms, living rooms, kitchens, and bathrooms. It can be used to regularly disinfect furniture, toys, tableware, etc., to protect the health of your family.

[0062] Medical facilities: Hospital wards, operating rooms, dressing rooms, treatment rooms, etc., need to be strictly disinfected when no one is around. Delayed ultraviolet disinfection lamps can automatically turn on and off according to the set time to ensure the smooth progress of disinfection and effectively prevent cross-infection.

[0063] Laboratory: In biological laboratories, chemical laboratories, and other places, it is used to disinfect experimental equipment, instruments, work surfaces, etc., to ensure the sterility and safety of the experimental environment. The delay function allows the experimenters to leave calmly after preparing the experimental materials and then start the disinfection process.

[0064] Food processing industry: Delayed ultraviolet disinfection lamps can be used in production workshops, warehouses and other areas of food processing plants to disinfect the environment and equipment during non-production hours, ensuring the hygiene and safety of the food production process and preventing bacteria and viruses from contaminating the food.

[0065] Public places such as school classrooms, libraries, offices, hotels, shopping malls, cinemas and other crowded places can use delayed ultraviolet disinfection lamps to disinfect indoor air and public facilities after closing or suspending business, providing people with a healthier and safer public environment.

[0066] Key points for purchasing

[0067] Ultraviolet (UV) intensity: UV intensity is a key factor affecting disinfection effectiveness. Disinfection lamps that meet national standards and have sufficient UV intensity should be selected. Generally speaking, the UV intensity of a UV germicidal lamp should not be less than 70 μW / cm².

[0068] Delay range and accuracy: Different delay UV disinfection lamps have different delay ranges and accuracy. Users should choose the appropriate product according to their actual needs. For example, in home use, a long delay time and high accuracy may not be necessary, while in some professional places, such as hospital operating rooms, more precise delay control and a longer delay range are required.

[0069] Lamp quality: The lamp is the core component of the ultraviolet disinfection lamp, and its quality directly affects the disinfection effect and service life. High-quality lamps should be made of quartz glass, which has good ultraviolet transmittance and stability. At the same time, attention should also be paid to whether the lamp's power, wavelength and other parameters meet the requirements.

[0070] Control methods: Common control methods include mechanical knob, touch, and remote control. Mechanical knob is simple and intuitive to operate, but its accuracy is relatively low. Touch is convenient and aesthetically pleasing, but it may cause misoperation in humid environments. Remote control is more flexible and convenient, and is suitable for places where direct operation is inconvenient. Users can choose the appropriate control method according to their usage habits and the characteristics of the place.

[0071] Brand and Quality Certification: Choosing a well-known brand of delayed-action UV disinfection lamps ensures better quality and after-sales service. In addition, you should check whether the product has passed relevant quality certifications, such as the National Compulsory Product Certification (CCC certification), to ensure the safety and reliability of the product.
