Description

Technical Field

[0001] The present invention belongs to the technical field of air filtration, and particularly relates to an air filtration nasal plug. Background Art

[0002] A mask is a common daily hygienic and epidemic prevention product, worn over the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances, and is made of materials such as gauze or paper; the mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, or when working in a polluted environment such as dust, wearing a mask has a very good effect.

[0003] However, wearing a mask for a long time can cause ear pain and difficulty in breathing, with poor comfort; at the same time, it will affect facial expressions and appearance, and is not aesthetically pleasing; in addition, disposable masks waste resources, while cloth masks need to be washed frequently and are difficult to reuse.

[0004] Therefore, a new solution for an air filtration device is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an air filtration nasal plug with a simple structure, comfortable use, high efficiency and the ability to be reused.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: An air filtration nasal plug, including a nasal plug main body, characterized in that an anti-detachment sealing pad is provided on the outer wall of the nasal plug main body, an air flow groove penetrating up and down is provided on the nasal plug main body, a filter element is provided in the air flow groove, and a limiting block is circumferentially provided at the bottom of the nasal plug main body.

[0007] Further, the filter element includes a HEPA filter screen and an activated carbon layer.

[0008] Further, the material of the nasal plug main body is medical silicone.

[0009] Further, a micro fan is provided in the air flow groove The beneficial effects of the present invention are as follows: The structure is simple and comfortable to use. The medical silicone material is soft and fits the nasal cavity well. There is no need for ear hooks, avoiding ear pain and difficulty in breathing caused by long-term wearing. It is small in size and almost invisible after wearing, does not affect facial expressions and daily social interactions, and the replaceable filter element design reduces the waste of resources of disposable masks and reduces the use cost.

[0010] The above description is only an overview of the technical solution of the present invention. In order to be able to understand the technical means of the present invention more clearly and implement it according to the content of the specification, the following takes the preferred embodiments of the present invention and combines with the drawings to describe in detail as follows. Brief Description of the Drawings

[0015] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0016] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] Please refer to Figure 1 , an air-filtering nasal plug shown in a preferred embodiment of the present application, includes a nasal plug body 1. An anti-detachment sealing pad 2 is provided on the outer wall of the nasal plug body 1, and an air flow groove 3 that penetrates up and down is provided on the nasal plug body 1; Specifically, a limiting block 5 is circumferentially provided at the bottom of the nasal plug body 1, and a filter element 4 is provided in the air flow groove 3; the nasal plug is restricted by the limiting block 5 to prevent over-deep or over-shallow wearing, and the anti-detachment sealing pad 2 is used to ensure stable wearing without falling off.

[0018] More specifically, the filter element 4 includes a HEPA filter screen and an activated carbon layer, which can filter particulate matter, bacteria and viruses, can be disassembled and replaced, can use different filter elements 4 according to the usage scenario, and can be reused, and the filtering effect reaches the N95 level.

[0019] Preferably, the material of the nasal plug body 1 is medical-grade silicone, which is soft and comfortable and suitable for different nasal shapes.

[0020] In some embodiments, a micro fan is further provided in the air flow groove 3 to assist breathing.

[0021] In summary, the present invention proposes a nasal plug type air filtration and purification solution, which is comfortable to use and convenient to wear, applicable to various usage scenarios such as daily protection and medical care, and has a strong filtering effect and can be reused, having great advantages compared with the prior art.
