Description

Portable sterilization equipment based on contact propagation and operation method thereof

Technical Field

The invention relates to the technical field of virus epidemic prevention, in particular to portable sterilization equipment based on contact propagation and an operation method thereof.

Background

According to the diagnosis and treatment scheme for pneumonia infected by novel coronavirus (trial fifth edition), respiratory droplets and contact transmission are main transmission ways, so that an elevator serving as a public facility becomes a high-risk source of the novel coronavirus infection.

According to the public protection guideline for pneumonia infected by novel coronavirus published by the public health publishing house of people at 28.1.2020, the new coronavirus is not high temperature resistant, and other virus research results are referred to: (1) the rabies virus is not high-temperature resistant, and is inactivated at 50 ℃ for 1 hour and inactivated at 100 ℃ for 2 minutes; (2) avian influenza viruses are generally sensitive to heat, and can be inactivated by heating at 65 ℃ for 30 minutes and boiling (100 ℃) for more than 2 minutes, so that the time required for virus inactivation decreases exponentially with the increase of temperature. Therefore, it is speculated that the new coronavirus can be inactivated for 30 minutes above 56 ℃, can also be inactivated for several minutes at a high temperature of 100 ℃, and can be inactivated for ten seconds or even instantaneously at a high temperature of 500 ℃ and above 300 ℃. There is therefore a need to design a portable sterilisation device to eliminate the risk of contact propagation from direct use of the elevator keys.

Referring to fig. 1-4, a portable sterilization device based on contact propagation according to an embodiment of the present invention specifically includes a housing 7, where the housing 7 may be made of plastic or metal, an ignition device 2 is slidably connected in the housing 1, and the ignition device 2 may slide up and down in the housing 7, and is preferably a common lighter. A contact probe (in this embodiment, the contact probe 1 is sleeved on the ignition device 2) is fixedly connected to the ignition device 2. The top of the contact probe 1 is arranged right above the ignition device 2, and the bottom of the contact probe 1 is sleeved at the upper part of the body of the ignition device 2. An ignition key 3 is arranged at the end of the ignition device 2 remote from the contact probe 1. When the contact probe is used, the top of the contact probe 1 is contacted with the key and pressed down, and after the key is pressed down, the ignition device key 3 is pressed down to open the fire to sterilize and disinfect the contact probe 1. In the embodiment, the contact probe and the ignition device 2 are wrapped by the shell 7 when not in use, so that the contact probe 1 and the ignition device 2 are not in contact with the outside, and cross infection of the contact probe 1 and the ignition device 2 (most mainly the contact probe 1) when in use is avoided, for example, when an elevator is pressed, high-temperature sterilization and disinfection cannot be performed by means of ignition when the elevator is pressed due to the fact that the elevator is crowded.

In the present embodiment, the top of the contact probe 1 is a contact head (not labeled in the figure), the longitudinal cross section of the contact head is a triangular structure, the bottom of the contact probe 1 is a hollow structure, and the shape of the hollow structure matches with the shape of the body of the ignition device 1. The material of the contact probe 1 is stainless steel wire (preferably iron wire or copper wire) with a diameter of 1-3 mm. Wherein, the contact of the contact head is just positioned in the middle of the outer flame of the flame outlet of the ignition device 2. The outer flame temperature of a common lighter is about 300-.

Referring to fig. 1-4, at least one limiting ring 4 is fixedly connected to the body of the ignition device 2 (in this embodiment, two limiting rings 4 are fixedly connected to the body of the ignition device 2, and are respectively connected to the upper portion and the lower portion of the body), a connecting rod 5 is fixedly mounted on the limiting ring 4, a longitudinal hollow sliding groove 8 is formed in a housing 7, and the connecting rod 5 penetrates through the hollow sliding groove 8 in the housing 7 to be connected with an external sliding block 6. When the ignition device is used, the sliding block 6 is pressed to drive the ignition device 2 to slide upwards through the connecting rod 5 until the ignition device key 3 on the ignition device 1 extends out of the shell 7, and the ignition device 2 is retracted into the shell 7 after high-temperature sterilization and disinfection.

In this embodiment, the inner side of the sliding block 6 is disposed in the hollow sliding groove 8, and the inner side of the sliding block 6 is tightly attached to the hollow sliding groove 8, so that the sliding block 6 drives the ignition device 2 to move upward, and after the ignition device key 3 extends out of the housing 7, the ignition device 2 does not fall downward due to the friction between the sliding block 6 and the hollow sliding groove 8, and the outer side of the sliding block 6 is disposed outside the hollow sliding groove 8. When ignition is carried out, the sliding block 6 on the shell 7 is held by the palm of the hand, the ignition device key 3 is pressed by the thumb to carry out high-temperature disinfection operation, and the other four fingers in the hand can easily hold the sliding block 6 to prevent the ignition device from falling downwards.

Referring to fig. 1-4, in the present embodiment, a connecting hole (not shown) is formed in the sliding block 6 for the connecting rod 5 to pass through, and the shape of the connecting hole matches the shape of the connecting rod 5. And the end of the connecting rod 5 extends out of the outer surface of the sliding block 6, and the end of the connecting rod 5 is wrapped by a sliding sleeve (not marked in the figure). The sliding block 6 is conveniently pushed up and down when in use by the way that the tail end of the connecting rod 5 is wrapped by a sliding sleeve (not marked in the figure) through the tail end extending out of the outer surface of the sliding block 6.

The internal overall height of the housing 7 is at least the sum of the heights of the contact probe 1 and the ignition device 2, ensuring that the housing 7 can completely enclose the contact probe 1 and the ignition device 2 when no key operation is performed. The hollow chute 8 is of a rectangular structure. In this embodiment, the outer shell is made of a metal square tube product, aluminum alloy or stainless steel, the cross-sectional size of the square tube is 50 × 30 × 1.5mm, the length of the square tube is 200mm, and the size of the hollow chute 8 is 120 × 5 mm.

The embodiment of the invention also provides a key operation method based on the portable sterilization equipment, which specifically comprises the following steps: when a key is needed, the ignition device slides out of the shell; the top of a contact head of a contact probe arranged on the ignition device is used for touching and pressing a key; after the key is touched and pressed, pressing a key of an ignition device to ignite and burn a contact head of the contact probe for sterilization; after sterilization, the sliding block is slid to completely retract the contact probe into the housing. In step S3, the contact probe appears reddish or the burning time is not less than 12S, and the ignition device can be turned off.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the invention as defined by the appended claims. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
