Description

Technical Field

[0001] This invention relates to the field of disinfection equipment technology, specifically a high-energy ion disinfection device for sterilizing and disinfecting the surfaces of objects such as buttons. Background Technology

[0002] During the use of elevators and bank ATMs, the buttons on these machines are exposed. Due to factors such as bacteria and viruses in the air and on the user's fingers, the surface of the buttons can become contaminated with bacteria and viruses during use, thereby increasing the risk of disease transmission.

[0003] In existing technologies, the most common disinfection method for buttons on elevators and bank ATMs is manual spraying of disinfectant. This method is not only labor-intensive but also inefficient, failing to ensure disinfection after each spray, thus compromising disinfection effectiveness. To address this, automated disinfectant spraying systems have emerged, such as the Chinese invention patent with application number CN202010436796.0, entitled "Automatic Disinfection System for Elevator Car Operating Buttons," and application number CN202220626359.X, entitled "Elevator Button Disinfection Device." Simultaneously, automated disinfectant wiping systems have also appeared, such as the Chinese invention patent with application number CN202110559025.5, entitled "A Non-Cross-Contact Elevator Floor Button System." However, these disinfection methods all rely on disinfectant solutions, which have many drawbacks such as secondary pollution, reduced lifespan of ammonium nitrate buttons, poor economic efficiency, inconvenience in subsequent ammonium nitrate button pressure after being contaminated with disinfectant, and high mechanical failure rate. Moreover, the designed structure is relatively complex, and the processing cost is too high and the processing is difficult, making it impossible to promote and apply them.

[0004] Meanwhile, existing technologies also include disinfection devices that use ultraviolet light and ozone for sterilization, such as the Chinese invention patent with application number CN202221422505.3 and patent name "A Disinfection Device for Elevator Buttons". However, ultraviolet light needs to be continuously sterilized for more than 30 minutes to achieve a sterilization effect, so it cannot be practically applied to the disinfection of elevator buttons. Moreover, its long working time makes it easy for ultraviolet light to cause harm to the human body, limiting its application scenarios and failing to meet the need for disinfection of button surfaces at any time.

[0005] Academic data shows that negative ions severely penetrate and damage bacterial cell membranes, and for viruses, they can destroy their RNA or DNA molecular chains, thereby killing bacteria and viruses. Secondly, the negative ion effect can also break gas molecular bonds, generating free radicals such as monatomic molecules, negative oxygen ions, OH ions, and free oxygen atoms. These substances have extremely strong activation and oxidation capabilities, exhibiting strong killing power against bacteria and viruses, thus improving the disinfection rate. Finally, negative ions are also beneficial to the human body and are known as "air vitamins." However, in our numerous experiments, we found that some bacteria and viruses are highly resistant to negative ions, making them difficult to kill using only negative ions, and the disinfection effect is unlikely to meet national disinfection standards. However, bacteria and viruses that are highly resistant to negative ions are more sensitive to positive ions. Alternating between positive and negative ions to bombard bacteria and viruses can ultimately achieve a near 100% disinfection rate.

[0006] Based on this, we have developed a high-energy ion disinfection device that has no internal moving mechanical parts, does not consume disinfectants, and has no toxic side effects. By placing a high-energy ion discharge head above the buttons on elevators and ATMs, and grounding the surface of the buttons while insulating the surrounding area, the device utilizes the electric field attraction of the ground to attract positive and negative ions, drawing them to the button surface. The high-energy ion discharge head then continuously releases positive and negative ions to kill bacteria and viruses on the button surface, effectively disinfecting elevator buttons. Furthermore, by incorporating sensors, the device begins continuous operation once a person enters the elevator, enabling disinfection before and after pressing the buttons. This effectively solves the aforementioned problems and has received positive user feedback in practical applications. Its simple structure and strong practicality make it suitable for widespread application. Summary of the Invention

[0007] The purpose of this invention is to provide a high-energy ion disinfection device for sterilizing and disinfecting the surfaces of objects such as buttons. This device utilizes a high-energy ion discharge head positioned above the buttons on elevators and ATMs. The positive and negative ions released cyclically from this discharge head kill bacteria and viruses on the button surfaces. Specifically, the button surfaces are electrically grounded and insulated around their perimeter. The electric field attraction of the ground on the positive and negative ions draws the ions released from the discharge head towards the button surfaces, achieving precise control over the trajectory and target of the ions, thus improving the sterilization rate of bacteria and viruses on the button surfaces. Simultaneously, the cyclic release of positive and negative ions also provides effective disinfection for a small number of bacteria and viruses resistant to negative ions, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A high-energy ion disinfection device for sterilizing and disinfecting surfaces such as buttons, comprising:

[0010] A conductive disinfection layer covers the button surface and is grounded, used to adsorb high-energy ions released by the disinfection head;

[0011] A disinfection head is disposed on the periphery of the conductive disinfection layer and is used to circulate positive and negative high-energy ions to the surface of the conductive disinfection layer.

[0012] A high-energy ion generator, wherein the high-energy ion generator is used to control the release of high-energy ions from the sterilization head;

[0013] A controller for controlling the opening and closing of a high-energy ion generator.

[0014] As a further aspect of the present invention: the conductive disinfection layer includes a conductive layer and an insulating layer, the insulating layer covers the surface of the button, the conductive layer is disposed on the surface of the insulating layer, and the conductive layer is grounded through a grounding wire.

[0015] As a further embodiment of the present invention: the disinfection head includes an insulating sheath, a high-voltage wire and a discharge head. The insulating sheath is disposed on the outside of the insulating layer, and a high-voltage wire is disposed inside the insulating sheath. One end of the high-voltage wire is electrically connected to the discharge head disposed on the front side of the insulating sheath, and the discharge head is correspondingly disposed above the conductive layer. The other end of the high-voltage wire is electrically connected to a high-energy ion generator.

[0016] As a further aspect of the present invention: the controller is connected to a sensor, which is used to directly or indirectly monitor whether a user is present around the button.

[0017] As a further aspect of the present invention, the discharge head is a carbon fiber bundle.

[0018] As a further aspect of the present invention: the discharge head is a stainless steel negative ion needle.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. A conductive disinfection layer is placed on the button surface. A high-energy ion generator is controlled by a controller. The high-energy ion generator can circulate positive and negative high-energy ions onto the surface of the conductive disinfection layer through a disinfection head. The conductive layer on the surface of the conductive disinfection layer uses the electric field attraction of the earth on positive and negative ions to attract the positive and negative ions released by the discharge head to the surface of the conductive layer. This achieves precise control over the trajectory and target of the positive and negative ions, improving the disinfection rate of bacteria and viruses on the conductive layer surface, thus achieving the disinfection of bacteria and viruses on the button surface. At the same time, the circulating release of positive and negative ions also has a good disinfection effect on a few bacteria and viruses that are resistant to negative ions.

[0021] 2. By connecting the controller to the sensor, it is possible to monitor whether there are users around the button. For example, when a person enters the elevator, the elevator interior lights will turn on. The sensor can detect the elevator interior lights and transmit the signal to the controller, thereby enabling the controller to automatically control the high-energy ion generator to work. When a person enters the elevator, the high-energy ion generator can continuously disinfect the button surface through the disinfection head, which is easy to operate.

[0022] In summary, this invention uses positive and negative ion sterilization and disinfection, which effectively disinfects the button surface and enables automatic disinfection after pressing. This replaces the traditional method of disinfection with disinfectant, avoids secondary pollution, eliminates the need for manual disinfection, does not affect the normal use of the button, and does not cause harm to the human body. Furthermore, this invention has a simple structure, low processing cost, and strong practicality. Attached Figure Description

The insulating layer 9 covers the surface of the elevator button 8, and the conductive layer 7 is disposed on the surface of the insulating layer 9. The conductive layer 7 is grounded through a grounding wire 10. Figure 2 The conductive layers 7 are electrically connected to each other through wires 11 and electrically connected to the original ground wire in the elevator through grounding wire 10, so as to achieve grounding of the conductive layers 7.

[0031] Combination Figure 1 and Figure 4 The device also includes a disinfection head 12, which is disposed on the periphery of the conductive disinfection layer and is used to cyclically release positive and negative high-energy ions to the surface of the conductive disinfection layer. Figure 4 Preferably, to avoid interfering with the operator pressing the elevator button 8, the disinfection heads 12 are symmetrically arranged on both sides of the elevator button 8, that is, one disinfection head 12 is arranged on each side of the conductive disinfection layer. The disinfection heads 12 are fixedly mounted on the elevator panel 3. Preferably, combined with Figure 1 The disinfection head 12 includes an insulating sleeve 4, a high-voltage wire 5, and a discharge head 6. The insulating sleeve 4 is disposed on the outside of the insulating layer 9. Fixing the insulating sleeve 4 to the elevator panel 3 can fix the disinfection head 12. The high-voltage wire 5 is disposed inside the insulating sleeve 4. One end of the high-voltage wire 5 is electrically connected to the discharge head 6 disposed on the front side of the insulating sleeve 4. The discharge head 6 is disposed above the conductive layer 7. The discharge head 6 can be made of carbon fiber bundle or stainless steel negative ion needle. In this embodiment, the discharge head 6 is preferably made of carbon fiber bundle. The other end of the high-voltage wire 5 is electrically connected to the high-energy ion generator 2. Specifically, in conjunction with Figure 4 Each elevator button 8 is equipped with a disinfection head 12 on both sides, and the high-energy ion generator 2 is connected in parallel with multiple disinfection heads 12 via a high-voltage line 5.

[0032] This device also includes a high-energy ion generator 2, which is used to control the release of high-energy ions from the disinfection head 12. Specifically, in conjunction with... Figure 1 The high-energy ion generator 2 is obtained directly by purchase. By setting a positive high-voltage generator and an internal high-voltage generator inside, the discharge head 6 can cyclically release positive and negative high-energy ions. The high-energy ion generator 2 in this application preferably adopts a high-power small-particle-size negative ion generator with product number FZ-MA220V-007 and applicable area of ​​40㎡.

[0033] Combination Figure 1This device also includes a controller 1, which controls the opening and closing of the high-energy ion generator 2. The controller 1 is directly purchased and contains a single-board computer. The controller 1 controls the high-energy ion generator 2 via the single-board computer, a conventional technique familiar to those skilled in the art, and will not be described in detail. Preferably, to achieve the effect of timely automatic disinfection after pressing the button, the controller 1 is connected to a sensor. The sensor is used to directly or indirectly monitor whether there is a user around the button. This sensor is an AS0-AS-20 photosensitive sensor, which can be installed on the outside of the elevator panel 3 or inside the elevator near the light. The sensor installation is a conventional setup familiar to those skilled in the art, and will not be described in detail. When a passenger enters the elevator, the lights inside the elevator are turned on. The sensor senses the light, indirectly monitoring the presence of a user around the button and transmitting the signal to the controller 1. 1. This controls the high-energy ion generator 2 to operate, which in turn causes the discharge head 6 to release positive and negative high-energy ions. The positive and negative high-energy ions are adsorbed by the conductive layer 7, achieving disinfection and sterilization of the surface of the conductor layer 7. That is, when the elevator light is on, the elevator button 8 is disinfected. It should be noted that, as a conventional design familiar to those skilled in the art, in order to directly monitor whether passengers have entered the elevator, the above-mentioned sensor can be an infrared sensor to directly detect whether there are passengers in the elevator. If there are people in the elevator, the infrared sensor transmits a signal to the controller 1. The controller 1 controls the high-energy ion generator 2 to operate and perform disinfection. When there is no one in the elevator, the infrared sensor outputs a signal to the controller 1 to control the high-energy ion generator 2 to stop working, which saves energy. Infrared sensors can be purchased, and their use and installation principles are conventional technologies familiar to those skilled in the art, and will not be described in detail here.
