Background technique

As people pay more and more attention to hygiene issues, "epidemic prevention" has become the focus of attention. Nowadays, alcohol is generally used for disinfection in both homes and public areas, and cutting off the transmission route is the best prevention method. As a public space, elevators are exposed to many people with buttons, and they are also the places where the virus is most likely to spread. The closed elevator space and the buttons touched by people are easy to be infected with the virus. Therefore, residents may indeed have the risk of contact transmission of the virus when taking the elevator. The traditional method, for example, uses personal items such as keys as a key tool. Although it can prevent the virus from directly contacting the human body when pressing the elevator, people will not sterilize the personal items such as keys that have been in contact with the elevator keys. The next time the item is used, there is a risk of contracting the virus.

Detailed ways

The technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments.

As shown in FIG. 1 to FIG. 2 , a method for isolating keys provided in this embodiment includes the following steps:

S1: Take a mechanical pencil 1 with a pen cap 12, remove the pen cap 12, take a cotton ball dipped in alcohol, put it into the pen cap 12, and close the pen cap 12;

S2: When it is necessary to press the elevator button, take out the automatic lead body 11 from the cap 12, and press the pencil button 113 at the top of the automatic lead body 11 to push the pencil lead 112 out of the pencil barrel 111, and then hold the pencil barrel 111 , press the elevator button with the refill 112;

S3: After finishing pressing the elevator button, cut off a small part of the end of the refill 112 that was originally in contact with the elevator button, so that the part of the refill 112 that was in contact with the elevator button was separated from the mechanical pencil 1;

S4 : retract the automatic pencil 1 , insert the automatic lead body 11 into the pen cap 12 , and sterilize the tip of the automatic lead body 11 with the alcohol cotton ball 2 pre-placed in the pen cap 12 .

In order to ensure the sterilization and disinfection effect of the alcohol cotton ball 2, further, the alcohol solubility in the alcohol cotton ball 2 is between 70% and 75%, and the alcohol at this solubility can achieve a better sterilization and disinfection effect, because the alcohol When the solubility is too low, the alcohol enters the bacteria but cannot completely solidify the protein in the bacteria, so the sterilization effect cannot be achieved. When the alcohol concentration is too high, the surface protein of bacteria rapidly reacts with alcohol under high concentration of alcohol to produce a protective film, preventing alcohol from further entering the interior of the bacteria, so that it cannot be sterilized. Therefore, the alcohol solubility is controlled between 70% and 75%, which is beneficial to improve the disinfection and sterilization effect of the cotton ball on the tip of the automatic lead main body 11 . Further, 75% medical alcohol can be used, which has the best effect.

Further, the mechanical pencil 1 includes an automatic lead body 11 and a pen cap 12 sleeved on the surface of the automatic lead body 11. The use of the mechanical pencil 1 with the pen cap 12 can be convenient to carry, and can be used after the automatic lead body 11 completes pressing the elevator button. Sterilize the tip of the pen.

Further, the automatic lead main body 11 includes a pencil holder 111, a refill 112, and a pencil button 113;

In order to improve the effect of the mechanical pencil 1 in blocking virus transmission, further, the refill 112 adopts one of "4B", "5B" or "6B" type refills 112 with soft material and high graphite content. Since the refill 112 in the mechanical pencil 1 is made of a mixture of graphite and a binder, and the "4B" or "5B" or "6B" refill 112 is softer than other types of refills 112, therefore, in After the pen core 112 is in contact with the elevator keys, the end of the pen core 112 will produce thin-layer flake graphite or graphene material, and because the graphene has the function of filtering, in the process of the pen tip and the elevator key surface contacting, the graphite is The alkene can block the bacteria and viruses on the surface of the elevator keys from spreading to the refill 112, so as to achieve the effect of the mechanical pencil 1 blocking the spread of viruses. When contacting, it is easier to produce thin-layer flake graphite or graphene material, so it has a better effect of blocking virus transmission.

Example 1: When preparing to take the elevator, take out the mechanical pencil 1 in advance, put a 75% alcohol cotton ball 2 in the cap 12 of the mechanical pencil 1, and replace the cotton ball in time. After entering the elevator, take out the mechanical pencil 1 from the cap 12, press out the pencil lead 112, touch the button with the tip of the pencil, cut off the first section of the lead 112 after use, put on the cap 12 immediately, insert the pen tip into the cap 12, alcohol cotton Ball 2 sterilizes the nib.

Example 2: Since the outbreak of the new pneumonia, housing construction departments in major urban areas have launched a grid management model for joint epidemic prevention and control in residential areas. By introducing this method of isolating the button to the property management office of the community where it is located, the property management staff advocated it for the promotion and use of the property. When residents on most elevator floors go out to buy supplies, they use a mechanical pencil 1 to isolate and press the elevator buttons to take the elevator. In the past two weeks, grid personnel have registered and checked the temperature of people entering and leaving the community, and there have been no people entering or leaving the community with symptoms of suspected new pneumonia such as fever and cough.

Embodiment 3: With the continuous promotion of this method of isolating buttons, communities in other regions also successively adopt this method to press elevator buttons in a non-contact manner. And in some other fields, when non-contact pressing of the public button is required, this method has also been used, and it has also produced a good effect on isolating the pneumonia virus.

In a method for isolating buttons provided by the present invention, by using a mechanical pencil 1 to press an elevator button, the graphite refill 112 is in contact with the elevator button to effectively achieve a bacteriostatic effect. A small section of 112 sets of refills and 1 set of mechanical pencils are carried along with the sound, the pen tip is inserted into the pen cap 12, and the alcohol cotton ball 2 plays a role of disinfection. It avoids the spread of bacteria and viruses caused by the use of other personal items that are not disinfected in time after contacting the elevator buttons.

The present invention has been described in terms of preferred embodiments, and those skilled in the art will appreciate that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited by the specific embodiments disclosed herein, and other embodiments falling within the claims of the present application all belong to the protection scope of the present invention.
