Description

Technical Field

[0001] This utility model relates to the technical field of window openers, and in particular to a temperature-controlled automatic window opening system. Background Technology

[0002] An electric window opener consists of a motor, gearbox, and chain inside a housing. The high-speed motor is slowed down by the gearbox, increasing the output force, which opens or closes the window via the chain. The advantages of using an electric window opener are easy installation, simple wiring, and electric power; opening or closing only requires controlling the current, making it widely applicable. However, in the event of a power outage such as a fire, the window opener cannot open the window, and the dense smoke generated by the fire cannot be discharged, easily causing smoke inhalation or even death to occupants. Therefore, improvements are needed. Utility Model Content

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements.

[0022] Refer Figures 1 to 4 As shown, a temperature-controlled automatic window-opening system includes a window sash 2 hinged to a window frame 1, and a gas spring 3 and a window opener 4 connected between the window frame 1 and the window sash 2. The window opener 4 is fixed to the window frame 1 through a first bracket, and one end of its drive chain is connected to the window sash 2 through a temperature-controlled connecting device 5.

[0023] In this technical solution, the window frame, window sash, gas spring and window opener are all existing structures. The window sash is hinged to the window frame through conventional hinges, etc. The two sides of the window sash are respectively hinged to the piston rod of the gas spring through conventional hinge seats and hinge pins, etc. The other end of the gas spring housing (the end away from the telescopic end of the piston rod) is respectively hinged to the window frame through conventional hinge seats and hinge pins, etc. The temperature-controlled connecting device disconnects the connection between the drive chain and the window sash in cases such as a fire, and the gas spring automatically opens the window sash, which is beneficial to the discharge of thick smoke indoors. This temperature-controlled automatic window-opening system has a simple structure and can achieve automatic window opening in high-temperature situations such as a fire, avoiding the situation where thick smoke generated by an indoor fire cannot be discharged, etc., and improving the survival rate of people in cases such as a fire.

[0024] Exemplarily, refer to Figures 1 to 4 As shown, the temperature-controlled connecting device 5 includes a connecting bracket 51 fixed to the window sash 2, a connecting piece 52 connected to the drive chain, and a temperature-controlled connecting head 53 connected between the connecting bracket 51 and the connecting piece 52.

[0025] In this technical solution, the connecting bracket is a conventional L-shaped structure, which can directly utilize existing angle iron, etc., and is fixed to the corresponding side of the window sash with bolts. The connecting piece is a conventional metal sheet, etc., and the connecting bracket and the connecting piece are connected through the pin of the drive chain and the temperature control connector to realize the normal driving of the window opener. In case of fire, the temperature control connector will disconnect the connection between the connecting bracket and the connecting piece, and open the window sash through the gas spring.

[0026] For example, see Figures 1 to 4 As shown, the temperature control connector 53 includes a housing 531 suspended on the connecting bracket 51 and a connecting post 532 telescopically connected to the housing 531. The connecting post 532 is slidably inserted into the connecting bracket 51 and the connecting piece 52.

[0027] In this technical solution, the housing includes an upper housing and a lower housing that are riveted together. The connecting post is encapsulated inside the housing. The connecting post is slidably disposed inside the housing, with one end extending out of the housing. The extended part is slidably inserted into the connecting bracket and the connecting piece to realize the connection between the connecting bracket and the connecting piece. The housing is disposed on the connecting bracket by conventional male and female posts and bolts.

[0028] For example, see Figure 3 and Figure 4 As shown, a temperature control cavity is provided inside the housing 531, and the connecting column 532 abuts against the top wall of the temperature control cavity through the temperature-sensing glass ball 533.

[0029] In this technical solution, the two ends of the temperature-sensing glass ball are respectively abutted against the top wall of the temperature control cavity and the top of the connecting column. In the event of a fire or other situation, the temperature-sensing glass ball will break and will no longer be able to provide support for the connecting column.

[0030] For example, see Figure 3 and Figure 4 As shown, the top of the housing 531 is provided with a temperature sensing hole that connects to the temperature control cavity.

[0031] In this technical solution, the temperature sensing hole connects the space inside the shell to the outside, ensuring that the temperature sensing glass ball is in full contact with the outside air and that the temperature sensing glass ball breaks in time in the event of a fire.

[0032] For example, see Figure 3 and Figure 4 As shown, a limiting gasket 534 is provided between the top of the temperature-sensing glass ball 533 and the top wall of the temperature control cavity.

[0033] In this technical solution, the limiting gasket restricts the position of the temperature-sensing glass ball to prevent it from coming out of the temperature-sensing hole and out of the housing.

[0034] For example, see Figure 3 and Figure 4 As shown, the top of the connecting column 532 is provided with a positioning hole corresponding to the temperature-sensing glass ball 533.

[0035] In this technical solution, the shape and size of the positioning hole are determined according to the corresponding outer contour of the temperature-sensing glass column, and it is sufficient to accommodate the temperature-sensing glass column. This ensures full contact between the temperature-sensing glass ball and the connecting column, and at the same time, avoids the connecting column from being incorrectly retracted into the housing due to tilting of the temperature-sensing glass ball. In addition, the positioning hole can also accommodate the debris after the temperature-sensing glass ball breaks, so as to avoid interfering with the sliding of the connecting column.

[0036] For example, see Figure 3 and Figure 4 As shown, an annular boss protrudes from the top outer wall of the connecting column 532, and a spring 535 is provided between the annular boss and the bottom wall of the temperature control cavity.

[0037] In this technical solution, before the temperature-sensitive glass ball breaks, the end of the connecting column extends out of the shell under the action of the temperature-sensitive glass ball, and squeezes the spring through the annular protrusion. After the temperature-sensitive glass ball breaks, the spring releases elastic potential energy, which facilitates the connecting column to quickly retract into the shell, thereby disconnecting the connection between the connecting bracket and the connecting piece, and thus opening the window sash through the gas spring.

[0038] In summary, the temperature-controlled automatic window opening system of this utility model has a simple structure and can automatically open windows in high-temperature situations such as fires, preventing the dense smoke generated by indoor fires from being unable to be discharged, and improving the survival rate of people in fire situations.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0040] The above description is only a specific embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
