Description

Sign pen degassing unit

Technical Field

The utility model belongs to the technical field of disinfecting and sterilizing equipment, a disinfecting and sterilizing technology of stationery is related to, a sign pen degassing unit specifically says so.

Background

The sign pen is a tool which is frequently used by the public, in particular to public service windows such as banks, administrative centers and the like, the use frequency of the sign pen is very high, and if the sign pen cannot be sterilized simply and quickly, the sign pen can be easily used as a virus transmission medium.

At present, various patent technologies for disinfecting sign pens are available, such as:

chinese patent application No. 201820095594.2 discloses an office stationery disinfecting device, particularly for disinfecting sign pens. In this patent, the disinfectant solution can be injected onto the sponge on the inner surface of the collar. When the pen is inserted into the lantern ring, disinfectant is smeared on the pen holder through the sponge to be disinfected. The sterilized sign pen can be placed on the tray for use. The patent also discloses sterilizing by irradiating the articles on the tray with an ultraviolet light lamp. This patent has the following problems: 1. after the pen holder is coated with the disinfectant, the disinfectant can not be used immediately and can be used only after being dried or wiped; the disinfection of the pen insertion lantern ring, the supply of disinfectant, the placement of the disinfected pen and the like need manual participation, which can cause secondary pollution and is inconvenient to use; 2. although ultraviolet lamps are used for sterilization, there is no protection for the ultraviolet lamps. Potential safety hazards exist when the device is used in public places.

Chinese patent (patent application number: 201711280689.8) discloses a multifunctional sign pen with a novel structure, wherein a pen core is spirally wound on the periphery of an outer sleeve. When signing, the pen core is pulled down for use; an ultraviolet lamp is installed in the inner sleeve, and the ultraviolet rays can irradiate the external pen holder and the pen core through the transparent inner sleeve to sterilize the sign pen. When the pen is used, a user holds the spiral pen core with hands, so that the use experience is not good; the ultraviolet lamp inside irradiates outwards, the ultraviolet ray needs to penetrate through the inner sleeve and the outer sleeve, and the ultraviolet ray attenuation outside the spiral pen core which needs to be sterilized is the largest, so the sterilization effect is influenced.

Chinese patent application No. 201420471894.8 discloses a pen grip sterilizer. The sterilizer consists of a power supply, a sterilizing barrel, a vibration inductive switch on the sterilizing barrel and an ultraviolet sterilizing lamp in the sterilizing barrel. When the pen disinfection device is used, a pen is placed into the disinfection cylinder, and the ultraviolet disinfection lamp is started to disinfect the pen by knocking the disinfection cylinder. However, the outside of the disinfection cylinder cannot be disinfected, and the disinfection cylinder must be contacted when in use, so that the risk of virus transmission still exists.

Chinese patent (patent application No. 201020580460.3) discloses a novel disinfection pen container, which comprises a container body and a base, wherein a plurality of through holes for inserting pens are arranged in the container body in the vertical direction, a plurality of ultraviolet disinfection lamp tubes are arranged in the through holes, and spring pressing sheets for detecting whether the pens are put into the through holes are arranged at the bottoms of the through holes. The device adopts an ultraviolet lamp tube for disinfection. The ultraviolet lamp tube has low light intensity, and long irradiation time is required for thorough sterilization; the ultraviolet lamp tube contains mercury, which pollutes the environment once it is broken. Furthermore, the user still needs to grasp the end of the pen when inserting and removing it, which is not sterilized in the device. There is still a risk of virus transmission.

In summary, the main problems of the prior art are: 1. the disinfection time is long, or the disinfection process needs manual participation, and the use is inconvenient; 2. the sterilization is not thorough, and sterilization dead angles exist, so that cross infection is possibly caused.
