Description

Technical Field

[0001] This application relates to the field of face mask technology, and more specifically, to a breathable protective face mask. Background Technology

[0002] Breathable protective face shields are facial protective equipment that combines protection and breathability. They typically consist of a breathable face shield body, a filter layer, and comfortable wearing components. Through filters made of special materials or breathable structures, they block harmful substances such as dust and droplets while ensuring air circulation, reducing stuffiness during wear. They are suitable for scenarios requiring prolonged protection and breathability, such as daily protection and work in lightly dusty environments.

[0003] In actual use, while some protective masks can meet basic protection needs, their breathable structure design has limitations, making it difficult to effectively block impurities while ensuring smooth airflow inside the mask. In addition, the observation components of the masks are mostly integrated structures, and their light-blocking parts are prone to reduced clarity during use. Users are also unable to quickly switch observation modes according to actual needs, which to some extent affects the ease of use.

[0004] In view of this, this application proposes a breathable protective face shield. Utility Model Content

[0005] The purpose of this application is to provide a breathable protective face shield that solves the technical problems mentioned in the background art.

[0006] This application provides a breathable protective face shield, including a face shield body, with a viewing opening extending through the upper part of the front end face of the face shield body, and an eye shield assembly provided in front of the viewing opening;

[0007] The eye mask assembly includes a fixed frame located above the front end of the mask body. A light-blocking plate is fixedly connected inside the fixed frame, and a brush ring is fixedly connected to the rear end face of the fixed frame, with the brush ring fitting snugly against the mask body.

[0008] Optionally, wrapping straps are fixedly connected to both sides of the mask body, and binding straps and wrapping rings are fixedly connected to the opposite ends of the two wrapping straps.

[0009] Optionally, the front end of one end of the strap is sewn with Velcro, and the rear end of the mask body is secured with a soft rubber ring.

[0010] Optionally, a ventilation frame that communicates with the interior of the mask body is fixedly inserted into the bottom of the mask body, and a filter screen is fixedly connected inside the ventilation frame.

[0011] Optionally, an iron sheet is fixedly connected to the lower end face of the fixed frame, an extension block is fixedly connected to the front end face of the iron sheet, and a magnet plate is magnetically attracted to the rear end face of the iron sheet, and the magnet plate is fixedly connected to the mask body.

[0012] Optionally, a connecting strip is fixedly connected to the upper end face of the fixed frame, and a flipping rod is fixedly connected to the upper end face of the connecting strip. Both ends of the flipping rod are rotatably sleeved with fixed cylinders.

[0013] Optionally, a silicone sheet is fixedly connected to the inner wall of the fixing cylinder, and the outer wall of the flipping rod is tightly fitted with the silicone sheet, and the fixing cylinder is fixedly connected to the mask body.

[0014] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0015] 1. This application utilizes a ventilation frame and an internal filter to allow air to enter from below. The filter filters out large particles, preventing them from entering the mask body. The brush ring between the fixing frame and the mask body allows air to pass through, which, combined with the air intake through the viewing port, provides a good ventilation environment inside the mask body, ensuring smooth breathing for the user. While allowing air to pass through, the brush ring also acts as a barrier, reducing the entry of small particles such as external dust into the mask body, further optimizing internal air quality.

[0016] 2. This application uses an extension block to pull the iron sheet, separating the iron sheet from the magnetic plate. Under the limiting action of the fixed cylinder, the fixed frame and the light shield can be smoothly flipped. The connecting strip and the flipping rod flip synchronously. The flipping rod rotates inside the fixed cylinder, and the silicone sheet on the inner wall of the fixed cylinder can prevent it from flipping automatically. This allows the user to switch to directly observe the external state through the viewing port at any time according to their needs, making the operation flexible and convenient.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-3 This application provides a breathable protective face mask, including a face mask body 1. A viewing opening 10 is provided through the upper front end of the face mask body 1, and an eye mask assembly 6 is provided in front of the viewing opening 10. The eye mask assembly 6 includes a fixing frame 601 located above the front end of the face mask body 1. A light shield 602 is fixedly connected inside the fixing frame 601. A brush ring 603 is fixedly connected to the rear end of the fixing frame 601, and the brush ring 603 fits snugly against the face mask body 1. A ventilation frame 7 connected to the interior of the face mask body 1 is fixedly inserted into the bottom of the face mask body 1. A filter 8 is fixedly connected inside the ventilation frame 7. Air can enter from below through the ventilation frame 7 and the internal filter 8. The filter 8 can filter large particles of impurities and prevent impurities from entering the face mask body 1. The brush ring 603 between the fixing frame 601 and the face mask body 1 allows air to pass through. Together with the air intake of the viewing opening 10, it can provide a good breathable environment for the interior of the face mask body 1 and ensure that the user can breathe smoothly. The brush ring 603 allows air to pass through while also acting as a barrier, reducing the entry of small particles such as dust into the mask body 1 and further optimizing the internal air quality.

[0023] Both sides of the mask body 1 are fixedly connected with wrapping straps 2. The ends of the two wrapping straps 2 that are far apart from each other are fixedly connected with straps 3 and wrapping rings 5 ​​respectively. The front end of one end of the strap 3 is sewn with Velcro 4. The rear end of the mask body 1 is snapped with a soft rubber ring 9. The soft rubber ring 9 at the back of the mask body 1 fits the face, which can enhance the sealing and fit when wearing, and improve the comfort when using it. The wrapping straps 2 on both sides pass through the wrapping rings 5 ​​through the straps 3 and are then fixed by Velcro 4. The tightness can be flexibly adjusted to ensure that the mask body 1 fits the head firmly and is not easy to loosen.

[0024] A metal sheet 604 is fixedly connected to the lower end face of the fixed frame 601. An extension block 605 is fixedly connected to the front end face of the metal sheet 604. A magnetic plate 606 is magnetically attracted to the rear end face of the metal sheet 604, and the magnetic plate 606 is fixedly connected to the mask body 1. A connecting strip 607 is fixedly connected to the upper end face of the fixed frame 601. A flipping rod 608 is fixedly connected to the upper end face of the connecting strip 607. Fixed cylinders 609 are rotatably sleeved at both ends of the flipping rod 608. A silicone sheet 610 is fixedly connected to the inner wall of the fixed cylinder 609, and the outer wall of the flipping rod 608 is connected to the silicone sheet 610. The fixed cylinder 609 is fixedly connected to the mask body 1. The iron plate 604 is pulled by the extension block 605, so that the iron plate 604 is separated from the magnetic plate 606. Under the limiting action of the fixed cylinder 609, the fixed frame 601 and the light shield 602 can be flipped smoothly. The connecting strip 607 and the flipping rod 608 flip synchronously. The flipping rod 608 rotates inside the fixed cylinder 609. The silicone sheet 610 on the inner wall of the fixed cylinder 609 can prevent it from flipping automatically. It is convenient for users to switch to directly observe the external state through the viewing port 10 at any time according to their needs. The operation is flexible and convenient.

[0025] The adsorption and separation design of the iron sheet 604 and the magnetic plate 606 is simple to operate and can quickly fix and open the light shield 602, improving the convenience of use.

[0026] Working principle: The user puts the mask body 1 on his / her face. The soft rubber ring 9 at the back of the mask body 1 fits into the user's face. The mask body 1 covers the user's face. The wrapping straps 2 on both sides of the mask body 1 are tied around the back of the user's head. The strap 3 on one side of the wrapping strap 2 is passed through the wrapping loop 5 on the other side of the wrapping strap 2. After tightening the strap 3, the Velcro 4 is attached together to fix the mask body 1 in place. When the user breathes normally, air enters through the ventilation frame 7 below the mask body 1. The filter 8 inside the ventilation frame 7 filters out large particles of impurities. At the same time, air can also pass through the brush ring 603 between the fixed frame 601 and the mask body 1. Air can enter the mask body 1 through the viewing port 10, thus achieving good ventilation. When the user needs a clear view, the iron plate 604 can be pulled by the extension block 605. The iron plate 604 separates from the magnetic plate 606. Under the limit of the fixed cylinder 609, the iron plate 604 drives the fixed frame 601 and the light shield 602 to flip. The flipping of the fixed frame 601 drives the connecting strip 607 and the flipping rod 608 to flip synchronously. The two ends of the flipping rod 608 rotate in the two fixed cylinders 609 respectively. The silicone sheet 610 on the inner wall of the fixed cylinder 609 provides good anti-slip effect and prevents the flipping rod 608 from flipping automatically. When the fixed frame 601 and the light shield 602 are flipped open, the user can directly observe the external situation through the viewing port 10. When light blocking is required, the fixing frame 601 and the light-blocking plate 602 are flipped over to cover the viewing opening 10, and the iron sheet 604 and the magnetic plate 606 are attracted together.
