Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is the national phase entry of International Application PCT/CN2016/077310, filed on Mar. 25, 2016, which is based upon and claims priority to Chinese Patent Application No. 201610011197.8, filed on Jan. 8, 2016, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to goggles suitable for laboratories, chemical plants, and hospitals, and particularly to goggles, where the components of the goggles can be integrally and tightly connected with each other when changing external conditions.

BACKGROUND

In order to prevent infections or other injuries caused by potions and patient's blood spattering on the doctor's face, doctors need to wear protective eyepatches, which can be used together with masks, surgical caps, etc. It provides comprehensive protection to the doctor's head. The traditional eyepatches for medical purposes has poor air permeability and can not fit the face well, and because of their hard material, these are not comfortable to use, and get easily deformed when the external conditions change.

During the experiments in the laboratory and the production in the chemical plant, eyepatches are required. Because the various components of the existing eyepatches are assembled, they get easily deformed with the change in external conditions. As a result, the components can not be tightly connected to each other, thus generating seam and causing the harmful liquid to flow into the eyepatch and causing harm to the human body.

During the long distance transportation, the external conditions change, resulting in the deformation of the components of the assembled goggles and the weakening the protective capability.

Chinese patent No. 03237806.8 discloses a protective eyepatch, including an eyepatch frame and a lens. The lens is inserted in a groove with a certain depth at the inner side of the front end of the eyepatch frame which can cover the eyes tightly close to the periphery of eyes. On both sides of the eyepatch frame, a buckle is provided to attach to a fixed belt. On the periphery of the eyepatch frame, through holes are provided and a waterproof and breathable device is inserted in the through hole edge. The eyepatch frame includes the main eyepatch frame and the middle nose frame, and the main eyepatch frame and the middle nose frame overlap at the protuberance of the lens. However, the eyepatch needs to be provided with an additional waterproof and breathable device at the through hole, which is clamped at the through hole by the groove, thereby weakening the overall mechanical strength of the eyepatch frame. Besides, the waterproof and breathable device is composed of breathable parts and waterproof parts, the manufacturing process is complex and the usage cost is increased. The waterproof and breathable device needs to be in one-to-one correspondance with the through hole, so it is inconvenient to use. The eyepatch frame composed of the main eyepatch frame and the middle nose frame reduces the mechanical strength. After a long time of use, the joint is prone to break or produce a seam, and the droplets may enter inside the eyepatch from the seam. The protective eyepatch needs to be immersed in potions, and can not be directly and repeatedly used by high temperature sterilization, which also increases the usage cost and shortens the service life.
