Description

Technical Field

[0001] This application generally relates to the field of disinfection machine technology, and specifically to an ultraviolet disinfection machine. Background Technology

[0002] An ultraviolet (UV) sterilizer is a device that uses the bactericidal effect of ultraviolet light to kill bacteria, viruses, and other microorganisms. Its main function is to use the energy of UV photons to destroy the DNA (deoxyribonucleic acid) structure of various viruses, bacteria, and other pathogens, causing the DNA and nucleoprotein chains and other structural chains to break or undergo chemical polymerization reactions, thereby losing their ability to reproduce and replicate, thus achieving the effect of killing viruses and bacteria.

[0003] In existing technologies, ultraviolet lamps are connected to lamp holders via connectors, and the connectors and lamp holders are connected by snap-fit. However, this connection method makes it easy for there to be a gap between the connectors and the lamp holders, which causes the light to flicker. This results in unstable ultraviolet intensity received by different areas on the surface of the object being disinfected or in different areas of the space, thus failing to achieve the desired disinfection effect; and it can also easily damage the lamps.

[0034] Example 1

[0035] Please refer to Figures 1-7 This application provides an ultraviolet sterilizer, comprising:

[0036] Mounting column 1;

[0037] A plurality of ultraviolet lamp tube assemblies are provided, and the plurality of ultraviolet lamp tube assemblies are evenly arranged around the mounting column 1 in a circumferential direction.

[0038] The ultraviolet lamp assembly includes:

[0039] Lamp holder 2, which is rotatably mounted on the mounting post 1, has an installation space inside and a first opening at the bottom;

[0040] An ultraviolet lamp tube 3 is provided at one end of which a connecting part 31 is provided. The connecting part 31 passes through the first opening and is detachably electrically connected to the installation space. A connector 4 is sleeved on the outside of the connecting part 31.

[0041] Locking member 5 is sleeved on the outside of the ultraviolet lamp tube 3. The locking member 5 is threadedly connected to the outer wall of the lamp holder 2, and the locking member 5 abuts against the bottom end face of the connecting member 4.

[0042] Specifically, the rotation direction of the lamp holder 2 is parallel to the tangential direction of the mounting post 1; the outer contour dimension of the connecting part 31 is larger than the outer contour dimension of the lamp tube part of the ultraviolet lamp tube 3. In this embodiment, the connector 4 is snapped onto the outside of the connecting part 31. The outer contour dimension of the connector 4 is larger than the outer contour dimension of the connecting part 31 and smaller than the inner contour dimension of the locking member 5.

[0043] Specifically, in this embodiment, such as Figures 3-5As shown, the locking member 5 is a rotating locking cap, which is movably sleeved on the outside of the ultraviolet lamp tube 3. The end of the rotating locking cap away from the lamp holder 2 is bent inward to form a limiting edge. The inner wall of the rotating locking cap is provided with internal threads, and the outer surface of the lamp holder 2 is provided with external threads. When the ultraviolet lamp tube 3 is installed, the rotating locking cap is threadedly connected to the lamp holder 2, and the limiting edge abuts against the bottom end face of the connector 4 to lock the ultraviolet lamp tube 3.

[0044] Specifically, in this embodiment, three ultraviolet lamp tube assemblies are provided, and the interval between two adjacent ultraviolet lamp tube assemblies is 120°;

[0045] Working principle: Compared with the prior art where the connector 4 and lamp holder 2 are connected by a snap-fit, this application inserts the connector 31 of the ultraviolet lamp tube 3 into the installation space when installing the ultraviolet lamp tube 3. Then, the connector 4 is sleeved on the outside of the connector 31, and finally the ultraviolet lamp tube 3 is locked by the locking member 5. This makes the connection between the ultraviolet lamp tube 3 and the lamp holder 2 stable and free of play. When the ultraviolet lamp tube 3 is in use, it will not cause light flickering, so as to ensure that the ultraviolet intensity received by different areas of the surface of the object being disinfected or the space is stable, thereby improving the disinfection effect. At the same time, the lamp tube will not flicker during use, reducing the probability of lamp tube damage.

[0046] In some embodiments, the other end of the connecting portion 31 is provided with a contact 311 that is electrically connected to the ultraviolet lamp tube 3.

[0047] Specifically, such as Figure 6 As shown, in this embodiment, the other end of the connecting part 31 is provided with a contact 311, and the ultraviolet lamp tube 3 is electrically connected to the contact 311. When the ultraviolet lamp tube 3 is inserted into the connecting installation space, the ultraviolet lamp tube 3 is electrically connected to the power supply device through the contact 311.

[0048] In some embodiments, the mounting post 1 is further provided with a plurality of first handles 6, which are alternately arranged with the lamp holder 2; the two ends of the lamp holder 2 are connected to the first handles 6 through a damping component.

[0049] Specifically, in this embodiment, the mounting column 1 is provided with a plurality of first handles 6; in this embodiment, the first handle 6 is a ring structure, and when it is necessary to move the ultraviolet sterilizer, the first handle 6 can be held to pull the ultraviolet sterilizer to any position;

[0050] Specifically, in this embodiment, the first handle 6 and the lamp holder 2 are alternately arranged, and the two ends of the lamp holder 2 are rotatably connected to the first handle 6 through a damping assembly; in this embodiment, the damping assembly includes: a first fixing member 14, a damping rotating shaft 16, and a second fixing member 15. The first fixing member 14 is fixedly disposed inside the lamp holder 2, and the second fixing member 15 is fixedly disposed inside the first handle 6. The first fixing member 14 and the second fixing member 15 are connected by the damping rotating shaft 16; Figure 7 As shown, the damping shaft 16 includes: a shaft core and a housing, which are rotatably connected. Friction is generated between the shaft core and the housing through a damping material (such as rubber or grease) to provide rotational resistance. The shaft core is fixedly connected to the first fixing member 14, and the housing is fixedly connected to the second fixing member 15.

[0051] When the lamp holder 2 is manually rotated, it allows the lamp holder 2 to move freely relative to the first handle 6, thereby driving the ultraviolet lamp tube 3 to rotate to any height. At the same time, when the specified height is reached, the damping shaft provides damping torque to balance the torque of other external forces on the lamp holder 2, so that the ultraviolet lamp tube 3 stays at that height position, thereby achieving a better disinfection and sterilization effect for a large area.

[0052] In some embodiments, a second handle 7 is provided on the outer wall of the lamp holder 2.

[0053] Specifically, such as Figure 1 As shown, the outer wall of the lamp holder 2 is provided with a second handle 7 to facilitate pulling the ultraviolet lamp tube 3 to a specified height, so as to avoid the operator manually pulling the ultraviolet lamp tube 3 and causing damage to the ultraviolet lamp tube 3; at the same time, after the ultraviolet disinfection machine completes disinfection and sterilization, the temperature of the ultraviolet lamp tube 3 is high, and by pulling the second handle 7, the ultraviolet lamp tube 3 is reset to prevent the operator from being burned by the ultraviolet lamp tube 3.

[0054] In some embodiments, a photocatalyst plate 8 is provided between adjacent ultraviolet lamp assemblies.

[0055] Specifically, a photocatalyst plate 8 is provided between adjacent ultraviolet lamp tube components. The photocatalyst plate 8 can effectively disinfect and sterilize the surrounding air under the light of the ultraviolet lamp tube 3.

[0056] Specifically, the photocatalyst plate 8 is bolted to the mounting post 1 and is arranged along the length direction of the mounting post 1. The photocatalyst plate 8 has strip-shaped holes and round holes along the width direction and multiple sets along the length direction for air to pass through.

[0057] In some embodiments, the mounting post 1 includes a first tube 11 and a second tube 12, the first tube 11 being disposed at the bottom of the second tube 12; the first tube 11 having a plurality of ballasts corresponding to the ultraviolet lamp tube 3 inside, the mounting space having a first connector 17, the second tube 12 having a wire inside, one end of the wire being connected to the ballast, the other end of the wire being connected to the first connector 17, and the contact 311 being detachably electrically connected to the first connector 17.

[0058] Specifically, in this embodiment, three ballasts are provided inside the first tube body 11. The ballasts are arranged one-to-one with the ultraviolet lamp tube 3. The ballasts play a starting role and a current limiting role for the ultraviolet lamp tube 3 to ensure that the ultraviolet lamp tube 3 can start and work stably and reliably.

[0059] Specifically, the second tube 12 has a wire inside, which connects the ballast to the ultraviolet lamp 3 to supply power to the ultraviolet lamp 3.

[0060] In some embodiments, the outer wall of the second tube 12 is provided with a plurality of protective members 9, and the protective members 9 are provided one-to-one with the ultraviolet lamp tube 3; the protective members 9 are used to prevent the ultraviolet lamp tube 3 from colliding with the second tube 12 when the ultraviolet lamp tube 3 is retracted.

[0061] Specifically, in this embodiment, three protective components 9 are provided, and the three protective components 9 are respectively provided one-to-one with the three ultraviolet lamp tubes 3; when the ultraviolet lamp tubes 3 are retracted, the protective components 9 abut against the ultraviolet lamp tubes 3 to avoid the ultraviolet lamp tubes 3 colliding with the second tube body 12 and causing damage to the ultraviolet lamp tubes 3 and the second tube body 12.

[0062] In some embodiments, the bottom of the mounting post 1 is provided with casters 10.

[0063] Specifically, the bottom of the mounting column 1 is equipped with casters 10, which can move the ultraviolet sterilizer so that it can be easily moved to the designated location wherever sterilization is needed.

[0064] In some embodiments, a display control system is provided on the top of the mounting column 1.

[0065] Specifically, the top of the mounting column 1 is equipped with a display control system. The display control system can control the opening and closing of any ultraviolet lamp 3 and can count the cumulative usage time of each ultraviolet lamp 3, so as to make it easy to understand the usage time of the ultraviolet lamp 3 and replace it in time when the ultraviolet lamp 3 reaches the end of its life.

[0066] Specifically, the display control system includes a display screen 13 to realize control operations; as follows:

[0067] When the operator presses the power button, display screen 13 turns on. The operator can select the timer duration as needed: 30 minutes, 60 minutes, 90 minutes, or 120 minutes. After selection, a countdown begins after 20 seconds, accompanied by a beeping sound to remind the operator to leave as soon as possible. When the countdown reaches 10 seconds, the person icon on display screen 13 begins to flash, and the beeping sound becomes faster, reminding those present to leave even faster. When the countdown ends, the ultraviolet lamp 3 turns on, entering the sterilization and disinfection mode.

[0068] This application has three ultraviolet lamp tube assemblies, namely three ultraviolet lamp tubes 3. If the operator needs to turn off one or two of them, they only need to press the corresponding number 1 / 2 / 3 to select to turn the corresponding ultraviolet lamp tube 3 on or off. When the ultraviolet lamp tube 3 is in the on state, the corresponding button is displayed in orange-red. When the ultraviolet lamp tube 3 is in the off state, the corresponding lamp tube button is displayed in white. When the operator needs to check the usage time of a certain ultraviolet lamp tube 3, press the view button in the lower right corner. The corresponding ultraviolet lamp tube 3 will flash once, indicating that the current time displayed is the cumulative usage time of the corresponding ultraviolet lamp tube 3.

[0069] When the UV lamp 3 reaches the end of its lifespan and needs to be replaced, the corresponding UV lamp 3 button will flash to remind the operator that the UV lamp 3 has reached the end of its lifespan and needs to be replaced in time. After replacing the UV lamp 3 with a new one, the operator can press the corresponding button for 3 seconds and hear a beeping sound to reset the UV lamp 3's timer and start the timer again.

[0070] In this embodiment, a human body sensing device is also provided on the mounting column 1. The human body sensing device is connected to the display control system. The human body intelligent sensing device uses a microwave sensing sensor to detect human activity. When a human body or moving object enters its working area, it sends a signal to the display control system.
