Description

Video glasses

Technical Field

The utility model belongs to the technical field of the video glasses, in particular to video glasses with defogging function.

Background

The video glasses are a kind of virtual display worn on the head, and are an intelligent wearing device providing visual perception for users, and the player is designed into the glasses on the premise of playing video, also called glasses type display and portable cinema. The video glasses receive signals of output devices such as computers and game machines, and the signals are displayed in front of eyes of users on the display screen. Video glasses are becoming more and more popular due to their excellent performance in user visual experience, especially their wide application prospects in audio-visual entertainment.

Among the technique of current product, video glasses generally include glasses main part and eye-shade part, and the eye-shade is fixed at glasses main part inboard and the user face of laminating, so the eye-shade part adopts soft silica gel or materials such as sweat-absorbing sponge usually, when playing airtight shading effect, lets the user feel more comfortable. However, after the user uses the video glasses for a long time, the temperature in the eye cover rises, when hot air contacts the surface of the optical lens with lower temperature, one layer of water mist is generated on the surface of one side, close to the human eyes, of the optical lens, the eye cover is airtight, air circulation is not smooth, water vapor cannot be discharged, the image seen by the user from the video glasses is blurred, and therefore watching is affected.

Therefore, the prior art provides a solution, and an antifogging agent is provided, which utilizes a hydrophilic group in a preparation to adsorb water molecules in the air and reduce the surface tension of the water molecules, so that water vapor forms an ultrathin transparent water film on the surface of one side of an optical lens, which is close to the eyes, and the antifogging agent does not scatter incident light and interfere with the sight, thereby playing an antifogging role. However, when the method is used for defogging, a user needs to purchase an antifogging agent additionally, the use cost of the user is increased, the video glasses cannot be worn immediately after the antifogging agent is sprayed on an optical lens, and the video glasses can be worn and used after being air-dried, so that inconvenience is brought to the user. If a poor quality antifogging agent is purchased, it may also have adverse effects on the eye health of the user.

Patent application CN 201620564064.9 also provides another solution, namely to mount a fan on the eye mask. Be equipped with the fan mounting bracket in the eye-shade outside, the fan is installed on the fan mounting bracket, and two spaces intercommunication about fan mounting bracket and eye-shade are inside make the air and the external environment intercommunication in the video glasses to eliminate the fog that video glasses optical lens is close to people's eyes one side, guarantee that the user can normally watch the video. But add at the eye-shade outside and establish a fan mounting bracket, need the producer to redesign the eye-shade, make the mould, and the angle between fan mounting bracket and the eye-shade main part is close the right angle, and at the in-process of moulding plastics, the product manufacture craft of this kind of structure is more complicated, is more difficult to the drawing of patterns, and production is long consuming time, and mould maintenance frequency and cost all can increase. In addition, the eyeshade part needs to be attached to the face of a user when in use, so that the eyeshade is easily polluted and damaged, and once the condition occurs, the eyeshade needs to be replaced together with the fan, so that the use cost is further increased.

In conclusion, the prior art can not solve the problem of defogging well, so that the prior product needs to be improved.
