Detailed Description

Example 1

As shown in fig. 1-3, a mask auxiliary device for use in conjunction with a mask in special weather includes a flexible roll film fixedly connected above a nose bridge strip of the mask; the telescopic rolling film comprises a shell 1, a clockwork spring 2, a rope frame 3 and a waterproof film 4; the waterproof film 4 is a PE plastic film; the shell 1 is strip-shaped (shown as rectangle, or cylinder or other shapes), is symmetrically distributed across the bridge of the nose, and is provided with a strip-shaped film outlet groove 1-1 at the front side (the front side takes the wearing direction of human body as the reference); a winding column 5 which is transversely fixed is arranged in the shell 1, and core discs 6 for fixedly sleeving the clockwork spring 2 are arranged at two ends of the winding column 5; the rope frame 3 consists of ropes on two sides and a transverse rope at the end part, the outer side of the transverse rope at the outer end part is fixedly connected with a stop plate 7 with the width larger than that of the film outlet groove 1-1, and a pull ring 8 is arranged on the stop plate 7; the periphery of the waterproof film 4 is fixedly connected with the rope frame 3; the end part of the clockwork spring 2 is fixedly connected with the rope ends of the ropes on the two sides of the rope frame 3, and the waterproof film 4 in the rope frame 3 is wound on the winding column 5 through the torsion of the clockwork spring 2.

With the above structure, the waterproof film 4 and the rope frame 3 form an integral extending surface, and the connection between the side rope of the rope frame and the spring 2 makes the spring have two states: initial state: when the clockwork spring 2 contracts, the waterproof film 4 and the rope frame 3 are wound on the winding column 5 and the core plate 6, and the transverse rope at the outer end of the rope frame 3 is clamped at the opening 1-1 of the film outlet groove through the stop plate 7. An extension state: the pull ring 8 pulls the outer end transverse rope, so that the rope frame 3 drives the waterproof film 4 to expand outwards to form a shielding surface for shielding outside rain and snow. To make the shield face more stable in the extended state: and locking buttons 9 for braking the clockwork spring 2 are arranged at two ends of the shell 1. In order to make the extended shielding surface more three-dimensional and better wrap the nose and mouth of the human body, it is preferable that: the mask comprises a sticking hook which is stuck on the surface of the lower jaw of the mask, and the sticking hook is hung through a pull ring 8 to realize external wrapping.

When the mask is used in rainy days, a large amount of rainwater on the front side flows away from the surface of the waterproof film 4, and a small amount of rainwater on the upper side of the shell 1 can flow down along the two sides of the cheek of a human body, so that rainwater cannot be accumulated or blocked at the mask corresponding to the mouth and the nose, and normal breathing of a user cannot be influenced.

With the above structure, the waterproof film 4 is the main shielding surface, and whether the rope frame 3 is stretched stably can determine the state of the shielding surface, in order to achieve a more stable stretching state, the film outlet groove 1-1 is set as a narrow edge for only the waterproof film 4 to extend out, and two end parts of the film outlet groove 1-1 are extended out of the guide grooves for the ropes at the side of the rope frame 3 to extend out (as shown in fig. 4).

In order to make the application range of the auxiliary device wider and be suitable for various types of masks and different environments, the telescopic rolling film and the masks are detachably connected, wherein the connection comprises but is not limited to physical bonding, mechanical screw connection and buckle connection.

Preferably: at least one side surface of the shell 1 is a frustum, and the bottom of the shell is provided with a water outlet 1-2. The design 1-2 of the conical water outlet ensures that water cannot accumulate inside the shell 1 in the using process, and the shell can be quickly dried through the water outlet 1-2 after the use is finished; the better design is that two sides of casing 1 all are equipped with toper outlet 1-2, and the design of casing 1 bottom surface is the arc, and casing 1 inside at this moment is present the passageway that becomes the circulation, and the drainage in the use and after the use dries the effect better.

In addition, the invention also discloses a using method of the mask auxiliary device, which comprises the following steps:

s1, fixedly buckling a telescopic roll film at a nose bridge strip of the mask;

s2, pulling the pull ring 8 to a proper length, and pressing the locking button 9, wherein the waterproof film 4 overcomes the spring 2 and is pulled out of the shell 1 along the film outlet groove 1-1 under the action of the rope frame 3 to be in a plane extension state;

s3, adhering the adhesive hook to a proper position of the lower jaw of the mask, hooking the pull ring 8 on the adhesive hook, covering the mouth and nose positions of the mask with the front surface of the waterproof film 4, slightly dropping the side surface under the action of gravity of the rope frame 3, and adjusting to a proper position to shield rainwater on the side surface and leave a sufficient air flowing space;

s4, after the water-proof film is used up, the pull ring 8 is loosened, the locking button 9 is released, the water-proof film 4 retracts into the shell 1 under the torsion force of the clockwork spring 2, the sticking hook and the telescopic film are taken down, the side-standing water outlet 1-2 of the shell 1 of the telescopic film is downward until the inside of the shell is dried.

Example 2

As shown in fig. 5, the present embodiment is optimized based on embodiment 1, specifically as follows:

the shell 1 is in a two-end type, is symmetrical left and right, has two downward ends, and is integrally in an eave triangle shape to adapt to the facial features of a human body;

a middle rope is additionally arranged on the rope frame 3, based on the structure of the shell 1 of the I, the film outlet groove 1-1 and the winding column 5 are in a left-right two-section type, the middle parts of the film outlet groove and the winding column are connected through a core disc 6, the inner end of the middle rope is connected with the middle core disc 6 (the core disc 6 is designed into a trapezoidal structure), and the waterproof film 4 is divided into a left waterproof film and a right waterproof film;

and III, the pull ring 8 is provided with 3 connecting points which are respectively the center of the two outer end ropes of the rope frame 3 and the middle rope.
