Description

Quick defogging type goggles for medical epidemic prevention

Technical Field

The utility model relates to a goggles especially relates to a quick defogging type medical treatment goggles for epidemic prevention.

Background

Along with the outbreak of novel coronavirus epidemic situation, because novel coronavirus's infectivity is strong, the morbidity is high, except wearing the gauze mask protection, in the crowded public place of people, for individual protection safety, still need to wear goggles to prevent that novel coronavirus from invading the human body through the mucous membrane of eyes.

Because the goggles are worn closely on the face of a person, air is confined to the wearer's face and the space inside the goggles. After wearing for a long time, the shoes are easy to fog, thereby influencing people to be unable to see objects in front clearly and increasing danger for walking and doing things.

Patent publication No. CN2532831 discloses goggles, which are goggles for industrial purposes for protecting the eyes of a wearer from toxic splashes, chips, dust, or the like generated during production such as painting or grinding work. The goggles realize the function of preventing fogging by controlling the amount of air entering the inside of the goggle body through the air breather arranged on the top surface of the goggle body by using the throttle valve.

However, the throttle valve of the patent has no function of filtering viruses, and cannot block the invasion of novel coronavirus to eyes; in sudden environmental changes, such as sudden outdoor entry into the room in winter, a large amount of fog may develop on the lens of the goggles within a few seconds, and the fog cannot be quickly eliminated.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Example 1

The utility model provides a quick defogging type goggles for medical epidemic prevention, as shown in fig. 1-6, including lens 1, picture frame 2 and mirror area connecting piece 3, lens 1 is installed to picture frame 2, and the bilateral symmetry of picture frame 2 is provided with mirror area connecting piece 3, and mirror area connecting piece is used for being connected with the mirror area, and the mirror area is not drawn in the picture, and the mirror area is used for binding user's head, makes picture frame and people's head closely laminate.

When the user wears the ocular protection for a long time, since the sealed space between the ocular protection and the head of the user is a space, the temperature of the sealed space is easily increased, causing the skin in contact with the sealed space to sweat, thereby easily fogging the lens.

In order to make this device can get rid of the fog fast effectively, still include gasbag 4, filter mounting 5, filter piece 6, be provided with first bleeder vent 7 and second bleeder vent 8 on the left and right sides face of picture frame 2 respectively, first bleeder vent is for ventilating with the external world, the purpose is in order to discharge the air in the confined space, gasbag 4 is connected with the left surface of picture frame 2, and the business turn over gas port and the second bleeder vent 8 intercommunication of gasbag 4, filter mounting 5 fixes filter piece 6 on the right flank of picture frame 2, and filter piece 6 can cover first bleeder vent 7 completely, can ensure external air can not be directly be connected with the confined space through covering completely, external air must can get into the confined space after filtering through filtering piece 6.

Example 2

On the basis of embodiment 1, the upper and lower both ends symmetry of the first bleeder vent 7 of picture frame 2 side is provided with compresses tightly recess 21, and it comprises 3 layers of non-woven fabrics at least to filter piece 6, and this recess can be taken in and filter piece 6's marginal portion, plays the effect of pressing filter piece 6 in first bleeder vent 7 limit and encloses, ensures that the outside air can not directly get into in the confined space. Set up the symmetry at the upper and lower both ends of filtering mounting 5 and have the portion of compressing tightly 51, the material of filtering mounting 5 is plastics, and the material of picture frame 2 also is plastics, filters the portion of compressing tightly 51 of mounting 5 and the cooperation of compressing tightly recess 21 of picture frame 2 side, and this cooperation is closely cooperated, is difficult for making to filter mounting 5 landing.

The air bag 4 is an ellipsoid, an annular convex part 41 is arranged at the air inlet and outlet end of the air bag 4, an annular groove 81 is arranged in the second air hole 8, the annular convex part 41 of the air bag 4 is tightly matched with the annular groove 81 of the mirror frame 2, the annular groove 81 is used for clamping the annular convex part 41 of the air bag 4, the air bag 4 is made of rubber materials, and the annular convex part 41 of the air bag 4 is easily clamped in the annular groove 81 during assembly; in order to prevent the entry of outside air, the edge of the annular protrusion 41 of the airbag 4 and the frame 2 may be provided with a glass cement, or a cement substance like a glass cement.

When the filter piece 6 is made of a thick material, the width of the pressing groove 21 on the side surface of the frame 2 can be larger than the thickness of the pressing part 51 of the filter fixing piece 5, so that the pressing operation is convenient; meanwhile, the depth of the pressing groove 21 on the side surface of the lens frame 2 can be made larger than the length of the pressing part 51 of the filtering fixing piece 5 extending into the pressing groove 21.

This device is when actual production, and one set of this device can join in marriage 5 piece at least and filter

piece

6, and 6 use when filtering and exceed 4 hours after, will change to prevent novel coronavirus's invasion better, this device also can effectively prevent other viruses. When the filter fixing piece 5 is replaced, the filter piece 6 is clamped into the pressing groove 21 in a clamping mode, and the filter fixing piece 5 is directly pulled out forcibly.

When the device is used indoors or contacted with people suffering from novel coronavirus, the material of the filtering piece 6 is required to be replaced by the material similar to the N95 mask, and when the material is not available, a user can cut the N95 mask into the size of the filtering piece 6 to use.

When the user is in the ambient temperature sudden change from low to high, for example in winter, especially in northern area, carry out indoor from the open air, can produce a large amount of fog suddenly on the lens of goggles, the user can get rid of the fog through the mode of pressing the gasbag fast to make the lens turn back to clear state again, and then can guarantee user's safety, be unlikely to the user and can not produce danger such as tumble because of seeing the east and west suddenly, collision. The device is used outdoors for a long time, and can remove fog in a mode of pressing the air bag quickly when fog exists, generally speaking, the device is provided with the first air hole 7 and the filter piece 6 originally, and the probability of generating fog is much lower than that of a common goggles product when the external environment changes little.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
