a kind of goggles

Abstract

The invention provides a kind of goggles, which comprises a main frame of the goggles, a lens, an exhaust valve and a nose frame. Outside the lens, the lens is snapped and connected in the main frame of the goggles. The beneficial effects of the present invention are as follows: first, the exhaust valve, the nose frame and the main frame of the goggles are integrally formed, and the goggles as a whole can still be tightly connected when the external conditions change; Airflow circulation can be formed when wearing, so it is easy to wear and has good air permeability; third, the double-layer exhaust valve can effectively prevent liquids such as blood from splashing and entering the goggles.

Description

Technical field [0001] The invention relates to protective goggles suitable for laboratories, chemical plants, and hospitals, and specifically refers to a protective goggles that can maintain a tight connection as a whole when external conditions change. Background technique [0002] During the operation, doctors need to wear protective goggles in order to put medicines and the patient's blood splashed on the face to cause infection or other injuries. Generally, they can be used in conjunction with masks, surgical caps, etc., to provide comprehensive protection for the doctor’s head effect. Traditional medical eye masks have poor air permeability and cannot fit well to the face. Because of their hard materials, they are uncomfortable to use, and are prone to deformation when external conditions change. [0003] It is necessary to wear eye masks during laboratory experiments and chemical factory production. Because the components of the current eye masks are assembled, the componen...

Problems solved by technology

Traditional medical goggles have poor air permeability and cannot fit well on the face. Due to the hard material used, they are uncomfortable to use and are prone to deformation when external conditions change.

[0003] During laboratory experiments and chemical factory production, it is necessary to wear goggles. Since the components of the current goggles are assembled, the components are prone to deformation when external conditions occur, resulting in the inability to keep the components tightly connected. , resulting in gaps, allowing harmful liquids to enter the eye mask, causing harm to the human body

[0004] During long-distance transportation, external conditions change, resulting in deformation of the assembled goggle parts, resulting in weakened protection capabilities

[0005] The Chinese patent with the application number 03237806.8 discloses a protective goggle, including a goggle frame and lenses. , is provided with a buckle for connecting the fixing belt. There is a through hole around the eye mask frame, and a waterproof and breathable device is embedded in the through hole. The eye mask frame can be divided into the main eye mask frame and the nose middle frame. The protrusions of the eye mask are superimposed, but this kind of eye mask needs an additional waterproof and breathable device at the through hole, and the waterproof and breathable device is engaged in the through hole through the groove, thereby reducing the overall mechanical strength of the eye mask frame. In addition, the waterproof and breathable device Composed of breathable parts and waterproof parts, the manufacturing process is complicated, which also increases the cost of use, and the waterproof and breathable devices need to be in one-to-one correspondence with the through holes, so it is inconvenient to use. The eye mask composed of the main frame of the eye mask and the middle frame of the nose The frame reduces the mechanical strength. After long-term use, the joints are prone to breakage or gaps, and droplets may enter the inside of the glasses from the gaps. When this kind of protective goggles are disinfected, they need to be soaked in liquid medicine. Repeated use directly through high temperature sterilization, which also increases the cost of use and shortens the service life
