Description

Door handle with sterilization function {Doorknob be equipped bactericidal function}

The present invention relates to a door handle equipped with a sterilization function, and more specifically, it is capable of sterilizing and sterilizing components harmful to the human body, such as various pathogenic bacteria and viruses, which are buried on door handles of various entrances and handles of public transportation means. It is about a door handle with a function.

People open and close the door when entering and exiting a building including a house, and it is common to use a handle to open and close the door.

However, since most buildings (public institutions and facilities, educational facilities, hospitals, department stores, marts, shopping malls, airports, trains, passenger terminals, etc.) or facilities are used by an unspecified number of the public, It is a situation in which various harmful components such as viruses, including various harmful pathogenic bacteria and COVID-19, are buried. This is because the above harmful components are transferred to the door handle by human activity, ie, hand contact activity. In particular, more than 60,000 harmful bacteria and various harmful substances live on the human hand. It is currently being transferred to

However, although the door handles of some buildings or facilities are cleaned by a cleaner, it is difficult to completely sterilize and disinfect various harmful components, and the door handles of most buildings or facilities are not cleaned.

In addition, although a large number of various harmful bacteria and harmful components are transferred by the user's hand to the handles of public transportation used by unspecified people, especially buses and subways, sterilization and disinfection are hardly performed.

Various germs, viruses, and harmful components buried in these door handles can be spread widely by the gripping activity of an unspecified number of people and cause various types of diseases.

In order to solve this problem, door handle products using copper (Cu) or copper alloy that can sterilize and disinfect various harmful components are being released, and copper (Cu) and silver (Ag) are used for elevator buttons, etc. Film-type products are being distributed. However, products using copper or copper alloy have a problem in that oxidation phenomenon, that is, when copper or copper alloy is exposed to air, rust occurs on the surface.

On the other hand, for products that can sterilize and disinfect the handles of public transportation, prototypes have been developed that can sterilize and disinfect by spraying disinfectant solution with a disinfectant container and pump attached to the side of the bus handle, but lack of installation space due to volume problem, It has not been commercialized due to lack of practicality such as complexity of operation.

Technically, the Republic of Korea Intellectual Property Office registered patents, registered utility models, and published patent publications describe methods for sterilizing and sterilizing pathogenic bacteria and viruses on door handles by using metals such as copper or silver, or by spraying a light source such as ultraviolet rays or a disinfectant solution. The technique is disclosed.

However, when copper or copper alloy is exposed to the air, oxidation occurs and the problem that antibacterial activity is lowered cannot be overcome.

Patent No. 10-1975517 Sterilization Handle and Patent Publication No. 10-2018-0065810 Silver nano-coated sticky tape uses the antibacterial and sterilizing power of nano silver, but has a problem in that it has somewhat lower antibacterial power than copper or copper alloy.

Patent Publication 10-2016-0127431 Y-shaped smart handle sterilization device with excellent portability and sterilization disinfection discloses a technology that can sterilize bacteria or foreign substances by spraying ultraviolet rays and disinfectant solution, but this technology also replaces ultraviolet rays You don't have the skills to do it.

coupling the male thread protruding from the lower end of the lid to the female thread formed on one inner side of the upper end of the control unit;
A method comprising: rotating a male thread protruding from the lower end of the control unit to which the lid is coupled to a female thread formed on one inner side of the upper end of the body;
Door handle equipped with a sterilization function, characterized in that coupled through. When the user approaches the door within 3m, the sensor detects it and sends a signal to the controller;
a process in which the controller receives the signal transmitted by the sensor, controls the power between the battery and the near-infrared LED, and radiates the near-infrared to the internal body;
A process in which the emitted near-infrared radiation is transmitted to the body through the optical fiber of the internal body and the near-infrared radiation hole;
A process in which near-infrared radiation is radiated and delivered to the hand of a person holding the body through the near-infrared radiation hole formed in the body;
The process of self-sterilizing the body by emitting near-infrared rays for the next user;
Door handle equipped with a sterilization function, characterized in that it can be used through. delete
