Description

Technical Field

[0001] The utility model relates to the technical field of insulating glass, and particularly relates to an adjustable-pressure insulating glass. Background Art

[0002] Insulating glass is composed of two or more layers of glass plates, enclosing a hollow cavity, and the hollow cavity is supported by an aluminum frame, bonded and sealed with structural adhesive around. Dry gas is filled in the middle, and desiccant is filled in the aluminum frame to ensure the dryness of the air between the glass sheets. After retrieval, the prior art (application number: CN202021554064.3) records "an adjustable-pressure insulating glass, including at least one hollow cavity, a support frame capable of ventilating with the hollow cavity is arranged near the edge of the hollow cavity, and a structural adhesive layer is arranged outside the support frame; the adjustable-pressure insulating glass further includes a communicating pipe and a flexible air bag arranged outside the hollow cavity; the communicating pipe penetrates through the structural adhesive layer, one end is communicated with the support frame, and the other end is communicated with the flexible air bag. This application utilizes the principle of communicating vessels to connect the rigid hollow cavity and the flexible flexible air bag through the communicating pipe; when the external air pressure changes due to altitude or temperature changes, the flexible air bag deforms, adjusts the air pressure in the hollow cavity, and makes it balance with the external air pressure, avoiding the deformation of the glass plates of the insulating glass and ensuring the quality of the insulating glass products."

[0003] However, although the adjustable-pressure insulating glass in the prior art realizes the function of adjusting the internal air pressure of the insulating glass, there are still some deficiencies: the flexible air bags involved in the existing adjustable-pressure insulating glass are fixed on the glass surface in a large area, resulting in affecting the light transmittance and aesthetics of the glass. Secondly, one end of the communicating pipe is inserted into the hollow cavity of the glass from the structural adhesive at one end of the glass, resulting in damaging the flatness of the end face of the glass, and then making it inconvenient to install the glass and the window frame. Summary of the Utility Model

[0004] To overcome the defects existing in the prior art, the present utility model provides an adjustable-pressure insulating glass to solve the problems that the existing adjustable-pressure insulating glass affects the light transmittance and aesthetics of the glass and is inconvenient to install while realizing the voltage regulation function.

[0005] To achieve the above object, an adjustable-pressure insulating glass is provided, including: an insulating glass main body and a voltage regulating component. The insulating glass main body includes a hollow cavity inside, and an aluminum alloy spacer is arranged at the edge of the hollow cavity, and a drying cavity is opened inside the aluminum alloy spacer. An air flow channel is opened inside the insulating glass main body, and one end of the air flow channel is connected to the drying cavity. The voltage regulating component is installed on the outer surface of the insulating glass main body, and the voltage regulating component includes a micro air pump and an air pressure difference sensor. The inlet and outlet ends of the micro air pump are respectively connected with a first air pipe and a second air pipe. The upper end of the first air pipe is connected with a bent pipe, and the other end of the bent pipe is inserted into the outer port of the air flow channel.

[0006] Further, a desiccant is provided inside the drying chamber, and air holes are formed in the end face of the aluminum alloy spacer bar facing the hollow chamber.

[0007] Further, one detection end of the air pressure difference sensor is inserted into the hollow chamber through the hollow glass body by a pipeline, and the other detection end is in the external atmospheric environment.

[0008] Further, a sealing gasket is provided at the connection between the elbow pipe and the hollow glass body, and the sealing gasket and the hollow glass body are connected by structural adhesive. Meanwhile, sealing glue is provided at the connection between the elbow pipe and the sealing gasket.

[0009] Further, a control circuit board module is provided on the outer shell wall of the micro air pump, and the micro air pump is electrically connected to the air pressure difference sensor through the control circuit board module.

[0010] Further, a power supply box is installed on the outer shell wall of the micro air pump, a rechargeable battery is installed inside the power supply box, and a charging slot is formed on the outer wall of the power supply box.

[0011] Further, an electromagnetic valve is connected to the outside of the second air pipe, and the electromagnetic valve is electrically connected to the control circuit board module.

[0012] The beneficial effects of the present utility model are as follows:

[0013] 1. During use, the air pressure difference sensor is used to monitor the air pressure in the hollow chamber of the hollow glass body and the external atmospheric pressure. When the internal and external pressure differences are unbalanced, the micro air pump is started through the control circuit board module, and at the same time, the electromagnetic valve is opened. Then, through the first air pipe, the second air pipe, the elbow pipe and the air flow channel, the hollow chamber is evacuated or inflated to balance the internal and external pressure differences, thereby realizing the pressure regulating function.

[0014] 2. The pressure regulating component is installed at a corner of the hollow glass body, so that the area of the glass surface layer occupied is reduced, thereby ensuring the light transmittance and beauty of the hollow glass itself. At the same time, the elbow pipe is directly inserted into the hollow chamber, so that the outer edge space of the hollow glass is not occupied, which is convenient for the installation of the glass and the window sill frame.

[0015] 3. By using the air flow channel formed inside the hollow glass body and the connection between the air flow channel and the drying chamber, during the inflation process, the external air is conveyed to the drying chamber, and then dried by the desiccant inside, and then enters the hollow chamber through the through hole, which is convenient for drying and filtering the moisture carried by the external air, preventing the formation of water mist in the glass interlayer caused by the external humid air and affecting the light transmittance.

[0025] Among them, the hollow cavity 11 involved in this application is not filled with inert gas, but dry air, because the inert gas will be discharged during the exhaust pressure regulation process.
