Description

Helmet used when myopia person wears mask

Technical Field

The invention belongs to the technical field of A42B3/00 helmets, and particularly relates to a helmet used by myopia people when wearing a mask.

Background

The new mandatory national standard of electric bicycle safety technical specification is implemented in 2019 from 4 months, and the electric bicycle is required to be ridden by a safety helmet. On the other hand, as the haze weather in China increases day by day, when people go out, the consciousness of wearing the mask to prevent haze is gradually strengthened. When the myopia person wears the mask, the hot air generated by nose breathing easily atomizes the lenses of the myopia glasses, so that the user cannot see clearly the things in front. This phenomenon is more pronounced when the helmet is worn. How to solve the technical problem that when a person wears the mask, the lenses of the myopia glasses are atomized by breathing gas, and the technical problem needs to be solved when the person with myopia wears the mask to ride the electric bicycle.

Disclosure of Invention

The invention aims to provide a helmet for a myopia person to wear a mask, aiming at overcoming the defects of the prior art, and the helmet can prevent the mouth and nose breathing from generating fog on lenses of myopia glasses.

The technical solution of the invention is as follows:

helmet that uses when myopia personage wears gauze mask, including helmet shell and helmet lens, two clearances have been seted up in parallel on the helmet lens, and the inboard of helmet lens is provided with the elastic seal strip that corresponds with the clearance, and the elastic seal strip card realizes the sealed to the clearance in the clearance, the one end and the helmet lens swing joint of elastic seal strip, and the other end of elastic seal strip is the free end.

The invention conception of the invention is as follows: after the elastic seal strip is pulled out from the gap, the elastic seal strip can be bent towards the face from bottom to top. The free end of the elastic seal presses the mask at the positions on the two sides of the nose of the user, so that the upper part of the mask can be tightly attached to the face of the user, the breath of the nose rushes out from the upper edge of the mask, and the influence of the breath on the glasses is reduced. Because the mask is made of one layer of cloth, the mask has the function of assisting in fixing the free end of the elastic sealing strip, so that the free end of the elastic sealing strip is not easy to slide on a human face, and the compression effect of the elastic sealing strip on the upper portion of the mask is ensured. Meanwhile, after the elastic sealing strip leaves the gap, outside air enters from the gap in the riding process of a user, and air exchange occurs between the inside air and the outside air, so that the glasses can be further prevented from generating fog. If the rider does not wear the mask, the elastic seal is clamped in the gap, which is the same as that of a normal helmet.

As an improvement, a steel sheet is arranged inside the elastic seal. The steel sheet can strengthen the force and the deformation recovery performance of the elastic seal after deformation.

As a further improvement, the elastic seal comprises a sheet-shaped body and a strip-shaped body used for being clamped into the gap, wherein the strip-shaped body is arranged along the length direction of the sheet-shaped body and protrudes out of the outer surface of the sheet-shaped body. The free end of the elastic seal is twisted to make the outer side of the sheet and the strip contact with the human face together, and the elastic seal is twisted and tensioned between the helmet lens and the human face, so that the elastic seal can generate transverse tension to make the mask transversely attached to the human face, and further prevent the breath from rushing to the lens of the spectacles.

As a further improvement, the two gaps on the helmet lens are vertically arranged and are spaced by 3-6 cm. The distance between the two gaps is determined according to the structure of the human face.

In conclusion, the invention has the beneficial effects that: simple structure, modern design, convenient to use can prevent the lens of the aerial fog myopia glasses of breathing when riding passerby and wearing gauze mask, also can strengthen the helmet and ride passerby's head stability, improve passerby's safety and health.

Detailed Description

The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

Example 1

As shown in fig. 1, the helmet for a myopic person wearing a mask according to the present invention includes a helmet shell 1 and a helmet lens 2, where the helmet shell 1 and the helmet lens 2 are of a common structure in the prior art. The invention is only improved for the helmet lens 2.

As shown in fig. 1 and 2, two gaps 3 are arranged on the helmet lens 2 in parallel, the two gaps 3 on the helmet lens 2 are vertically arranged, and the gaps 3 enable air to circulate inside and outside the helmet. The width of the gap 3 is preferably 0.1-0.2 cm, and if the gap is too wide, the air flow inside and outside the helmet is large, and the face of a person is easy to be cooled when the air temperature is low. Because the mask has the function of keeping warm, the mask can resist some cold air entering the helmet from the gap 3 when the temperature is lower.

The apex of the gap 3 is located at the center of the helmet lens 2, so that the line of sight of the rider is not affected.

The inboard of helmet lens 2 is provided with the elasticity strip of paper used for sealing 4 that corresponds with clearance 3, and elasticity strip of paper used for sealing 4 card realizes the sealed to clearance 3 on clearance 3, the one end and the helmet lens 2 swing joint of elasticity strip of paper used for sealing 4, and the other end of elasticity strip of paper used for sealing 4 is the free end.

As shown in fig. 3, a steel sheet 41 is provided inside the elastic seal 4 to secure elasticity of the elastic seal 4. The outside of elastic seal 4 is wrapped up by silica gel to guarantee the travelling comfort. The elastic seal 4 comprises a plate 42 and a strip 43 for snapping into the gap 3, the top of the plate 42 is hinged to the helmet lens 2, and the plate 42 can rotate around the hinge point at a certain angle. The strip 43 is provided along the longitudinal direction of the sheet 42 and projects from the outer surface of the sheet 42, and the strip 43 is engaged with the gap 3.

The outer wall of a common mask is non-smooth, the free end of the elastic seal strip 4 is abutted against the mask, the free end is not prone to sliding, and in addition, the elastic force of the elastic seal strip 4 makes the elastic seal strip 4 not prone to moving after being abutted against the mask.

The spacing between the two gaps 3 can be chosen within 3-6 cm, depending on the volume of the helmet. Since the sheet-like body 42 can rotate around the hinge point at a certain angle, the elastic seal 4 has strong adaptability to the size of the human face.

Because the elastic seal 4 has a certain deformation capability, the free end of the elastic seal 4 is twisted towards the nose before the elastic seal 4 is pressed against the mask, and the twisting direction of the free end is shown in fig. 3. The free end of the elastic seal 4 is twisted and then abutted against the mask, the strip 43 and the outer side of the sheet 42 are pressed on the face of a person, the torsion of the elastic seal 4 stretches the mask transversely towards the two sides of the nose, the upper edge of the mask is favorably attached to the face of a rider, and the breathing gas can be further prevented from leaking upwards from the upper edge of the mask.
