Description

Technical Field

[0001] The utility model relates to the technical field of built-in venetian blinds, in particular to a built-in venetian blinds with an air pressure balancing function. Background Art

[0002] Insulating glass windows are commonly used in modern buildings for energy conservation, offering excellent thermal and sound insulation, and are often integrated with Venetian blinds for enhanced functionality. However, existing insulated Venetian blinds are often susceptible to temperature fluctuations during use, particularly when the window size is large, leading to increased deformation.

[0003] Specifically, during the cold winter months, the air inside insulating glass windows contracts due to thermal expansion and contraction, causing the glass panels to sag inward. Meanwhile, during the hot summer months, the air inside expands, potentially causing the glass panels to bulge. This problem not only affects the aesthetics and service life of the windows, but can also negatively impact their sealing and thermal insulation properties.

[0004] The primary cause of these issues is the pressure differential between the inside and outside of the window. When the outside temperature fluctuates significantly, the volume of air inside the insulating glass window changes accordingly, causing the glass panels to expand and contract. Therefore, there is an urgent need for a solution to adjust the air pressure inside the insulating glass window in real time to adapt to environmental changes and prevent window deformation.

[0065] The inner side of the top frame 11 is provided with an equipment installation groove 113. The top and bottom surfaces of the equipment installation groove 113 are provided with guide limit grooves 114 along the extension direction of the groove body. The equipment installation groove 113 is provided with a cover plate 115. In addition, a layer of heat insulation board 116 is also installed in the equipment installation groove.

[0066] The specific structure of the electric curtain driving device 40 is as follows:

[0067] The electric curtain driving device 40 includes a driving motor 41 , a motor base 42 , a venetian blind rotating shaft 43 , a rotating shaft end base 44 and a turning winding base 45 .

[0068] like Figure 4 As shown, the top and bottom surfaces of the motor seat 42 and the shaft end seat 44 are provided with guide rails 421 that match the guide limit groove 114, the guide rails 421 are inserted into the guide limit groove 114, and the motor seat 42 and the shaft end seat 44 are respectively placed at the two ends of the equipment installation groove 113; the drive motor 41 is installed in the motor seat 42, one end of the venetian blind shaft 43 is connected to the shaft of the drive motor 41, and the other end is inserted into the shaft end seat 44, the flip winding seat 45 includes two, and both are installed on the venetian blind shaft 43, and the drive rope of the venetian blind 30 is wound around the flip winding seat 45.

[0069] like Figure 5 As shown, the specific structure of the shaft end seat 44 is as follows: the shaft end seat 44 includes a bearing end 441 and a seat cavity 442; the control system 70, the MPPT charging controller 62 and the battery storage unit 63 are all installed in the seat cavity 442.

[0070] The specific installation locations of the air pressure sensor and micro solenoid valve are as follows: Figure 6 As shown: The first air pressure sensor 51 includes two, which are fixed on the top frame 11 and the bottom frame 12 respectively, and can detect the pressure difference in the vertical direction caused by airflow, temperature changes or other environmental factors. The sensors at the top and bottom can ensure that the air pressure changes inside the entire cavity are detected, especially the possible differences between the upper and lower parts. Among them, a first air vent 21 and a second air vent 22 are provided on the inner side of the bottom frame 12 and the corresponding glass panel 20. The second air pressure sensor 52 is installed in the bottom frame 12, corresponding to the first air vent 21, and is sealed with sealant.

[0071] In addition, the inner cavity of the bottom frame 12 is filled with silica gel desiccant for absorbing water vapor of the inflowing gas.

[0072] like Figure 7 As shown, the working principle of the utility model is as follows:

[0073] The photovoltaic panel 61 collects solar energy and converts it into electrical energy. The MPPT charge controller 62 uses the electrical energy output by the photovoltaic panel 61 to charge the battery storage unit 63. The battery storage unit 63 then powers the control system 70, the drive motor 41, the micro-solenoid valve 53, the first air pressure sensor 51, the second air pressure sensor 52, and so on. The two first air pressure sensors 51 respectively collect the air pressure values at the top and bottom of the hollow interlayer and transmit the signals to the control system 70, which calculates the average air pressure in the hollow interlayer. The second air pressure sensor 52 collects the air pressure value outside the hollow interlayer and transmits the signal to the control system 70, which calculates the absolute value of the difference between the average air pressure in the hollow interlayer and the external air pressure. When this absolute value is greater than a preset value, the control system 70 sends a control signal to the micro-solenoid valve 53 to open the valve. Then, when the absolute value of the difference between the internal and external air pressures is less than the preset value, the valve is closed.

[0074] The relevant preset values require adaptability experiments and calculations based on the actual window size and the toughness of the glass.
