Description

Technical Field

[0001] The invention relates to the technical field of ceiling exhaust fan installation, in particular to an energy-saving ceiling exhaust fan which is easy to assemble and disassemble. Background Art

[0002] An exhaust fan is an air conditioning appliance that uses an electric motor to rotate the blades to drive the airflow, thereby exchanging indoor and outdoor air. It is also called a ventilation fan. The purpose of exhaust is to remove indoor dirty air and regulate temperature and humidity. It is widely used in homes and public places. Exhaust fans, also known as negative pressure fans, negative pressure fans, etc., use air convection to keep the room in a negative pressure state, forming a suction force, continuously inhaling outdoor air, and expelling the stuffy air in the room, thereby achieving the effect of ventilation and cooling.

[0003] At present, with the improvement of the quality of life, exhaust fans are widely used in construction sites, large shopping malls, and home environments. Exhaust fans are required to be installed to ventilate the indoor air. The most commonly used ones are ceiling-mounted exhaust fans. In the prior art, there are two common methods for installing exhaust fans. The first is to fix the exhaust fan to the ceiling with fixing screws, but it is necessary to carry tools to screw the fixing screws one by one during installation and disassembly, which is inconvenient during installation. The second is to directly clamp the exhaust fan on the ceiling with a spring sheet. Although the installation is simple, the exhaust fan needs to be pulled down forcefully during disassembly, which can easily cause damage to the ceiling. Therefore, the above two exhaust fan installation methods have certain defects. To this end, we propose an energy-saving ceiling exhaust fan that is easy to disassemble and assemble.

[0020] In this solution, when installing the exhaust fan, the exhaust fan is placed inside the ceiling, the fixing frame 6 is clamped at the side of the ceiling, and the extrusion plate 7 is placed at the top of the ceiling. During the installation process, the extrusion plate 7 is driven by the installation component 5 to squeeze the ceiling, so that the ceiling is clamped between the fixing frame 6 and the extrusion plate 7, thereby fixing the exhaust fan to the ceiling. When disassembling, the extrusion plate 7 can be quickly moved away from the ceiling through the quick release component 8, thereby facilitating the disassembly of the exhaust fan.

[0021] The mounting assembly 5 includes four groups of fixing seats 9 fixedly connected to the housing 1, the four groups of fixing seats 9 are respectively installed at the top positions of the four groups of fixing frames 6, and a sleeve 10 is fixedly connected to the fixing seat 9, a tension spring 11 is fixedly connected inside the sleeve 10, the end of the tension spring 11 is fixedly connected to a sliding block 12 slidably connected to the sleeve 10, the end of the sliding block 12 is fixedly connected to an extrusion column 13 fixedly connected to the extrusion plate 7, the extrusion column 13 is slidably connected to the fixing frame 6, the top of the sleeve 10 is connected to a connector 14, the end of the connector 14 is connected to a connecting pipe 15 extending to the inside of the housing 1, and the end of the connecting pipe 15 is connected to a pressure control member 16; the pressure control member 16 includes four groups of supporting seats 17 fixedly connected to the housing 1, and the four groups of supporting seats 17 are symmetrically fixed to the outer housing 1 in pairs. Inside the shell 1, a pressure-controlling tube 18 is fixedly connected to the support seat 17, and the end of the pressure-controlling tube 18 is connected to a connecting tube 19 connected to the connecting tube 15, and a moving block 20 is slidably connected inside the pressure-controlling tube 18, and a moving member 21 is installed on the moving block 20; the moving member 21 includes four groups of connecting seats 22 fixedly connected to the outer shell 1, and the four groups of connecting seats 22 are symmetrically arranged in pairs, and two groups of connecting seats 22 on the same side of the outer shell 1 are rotatably connected to threaded tubes 23, and both ends of the threaded tube 23 are threadedly connected to threaded columns 24, and the thread directions of the two groups of threaded columns 24 located at the two ends of the threaded tube 23 are opposite, and the ends of the threaded columns 24 are fixedly connected to moving columns 25 fixedly connected to the moving block 20, so as to drive the moving block 20 to move and squeeze the air pressure inside the pressure-controlling tube 18 into the inside of the sleeve 10.

[0022] In this solution, during the installation process, the threaded tube 23 is rotated, and the threaded column 24 is moved by the rotation of the threaded tube 23. When the threaded column 24 moves, the moving column 25 will drive the moving block 20 to move. The gas inside the pressure-control tube 18 is squeezed into the connecting tube 19 through the movement of the moving block 20. The gas inside the pressure-control tube 18 is squeezed into the sleeve 10 through the action of the connecting tube 19, the connecting tube 15 and the connecting head 14, so that the air pressure inside the sleeve 10 increases. The sliding block 12 is moved by the action of the air pressure, and the extrusion column 13 and the extrusion plate 7 are driven to move by the movement of the sliding block 12. The exhaust fan is installed on the ceiling through the action of the extrusion plate 7.

[0023] In this solution, the tension spring 11 will be pulled into a stretched state during the movement of the sliding block 12, so the sliding block 12 can be easily reset by the action of the tension spring 11, thereby facilitating the rapid disassembly of the exhaust fan at a later time.

[0024] The quick-release assembly 8 includes a sliding sleeve 26 installed inside the pressure-controlling tube 18, the sliding sleeve 26 is slidably connected to the pressure-controlling tube 18, and a first through hole 27 is provided on the sliding sleeve 26, and a second through hole 28 adapted to the first through hole 27 is provided on the pressure-controlling tube 18, and the position of the second through hole 28 corresponds to the position of the sliding sleeve 26, a connecting piece 29 is fixedly connected inside the sliding sleeve 26, and a plurality of groups of air outlet holes 30 are provided on the connecting piece 29, one end of the connecting piece 29 is fixedly connected to a first spring 31 fixedly connected to the pressure-controlling tube 18, and the other end of the connecting piece 29 is connected to a pushing member 32 extending to the inside of the threaded tube 23, and the pushing member 32 is used to drive the sliding sleeve 26 to move. The sleeve 26 moves so that the first through hole 27 and the second through hole 28 correspond; the pushing member 32 includes a sliding column 33 fixedly connected to the connecting piece 29, the sliding column 33 extends to the inside of the threaded tube 23, and the sliding column 33 is slidably connected to the moving block 20, the moving column 25 and the threaded column 24, the end of the sliding column 33 is fixedly connected to a fixed block 34, the fixed block 34 is fixedly connected to a connecting column 35, the outer side of the connecting column 35 is fixedly connected to a movable block 36 slidably connected to the threaded tube 23, the threaded tube 23 is provided with a sliding groove 37 adapted to the movable block 36, and the end of the connecting column 35 is fixedly connected to a handle 38 slidably connected to the threaded tube 23.

[0025] In the present solution, when disassembling, the two sets of handles 38 on the threaded tube 23 are moved to the two end positions, and the movement of the handles 38 causes the connecting column 35 to drive the fixed block 34 to move, and the movement of the fixed block 34 causes the sliding column 33 to move, and the movement of the sliding column 33 drives the connecting piece 29 to move, and the movement of the connecting piece 29 causes the sliding sleeve 26 to move, and when the sliding sleeve 26 moves, the first through hole 27 and the second through hole 28 correspond to each other, and after the first through hole 27 and the second through hole 28 correspond, the pressure control tube 18 is in an unsealed state, and the air pressure inside the sleeve 10 is discharged at this time, and the sliding block 12 can be pulled to reset by the action of the tension spring 11, and the resetting of the sliding block 12 causes the extrusion column 13 and the extrusion plate 7 to move in the opposite direction and reset, and after the resetting of the extrusion plate 7, the extrusion plate 7 is away from the ceiling, so the extrusion plate 7 loses the extrusion effect of the ceiling, thereby facilitating the disassembly of the exhaust fan without causing damage to the ceiling.

[0026] Working principle: when installing the exhaust fan, the exhaust fan is placed inside the top of the ceiling, the fixing frame 6 is clamped at the side position of the ceiling, and the extrusion plate 7 is placed on the top of the ceiling. During the installation process, the threaded tube 23 is rotated, and the threaded column 24 is moved by the rotation of the threaded tube 23. When the threaded column 24 moves, the moving column 25 will drive the moving block 20 to move. The movement of the moving block 20 squeezes the gas inside the pressure-controlled tube 18 into the connecting tube 19. Through the action of the connecting tube 19, the connecting tube 15 and the connecting head 14, the gas inside the pressure-controlled tube 18 is squeezed into the sleeve 10, so that the air pressure inside the sleeve 10 increases, and the sliding block 12 is moved by the action of the air pressure. The extrusion column 13 and the extrusion plate 7 are driven to move by the movement of the sliding block 12. The exhaust fan is installed on the ceiling through the action of the extrusion plate 7. The exhaust fan can be quickly installed without carrying any tools during installation. During the installation process, the sliding sleeve 26 does not move, and the second through hole can be adjusted by the action of the sliding sleeve 26. 28 is sealed, so that the pressure control tube 18 is in a sealed state, so that the air pressure is completely squeezed into the sleeve 10, and when disassembling, the two groups of handles 38 on the threaded tube 23 are moved to the two end positions, and the connection column 35 drives the fixed block 34 to move through the movement of the handle 38, and the sliding column 33 moves through the movement of the fixed block 34, and the connecting piece 29 moves through the movement of the sliding column 33, and the sliding sleeve 26 moves through the movement of the connecting piece 29. When the sliding sleeve 26 moves, the first through hole 27 and the second through hole 28 correspond to each other. After the first through hole 27 and the second through hole 28 correspond to each other, the pressure control tube 18 is in an unsealed state, and the air pressure inside the sleeve 10 is discharged at this time, and the sliding block 12 can be pulled to reset through the action of the tension spring 11, and the resetting of the sliding block 12 makes the extrusion column 13 and the extrusion plate 7 move in the opposite direction and reset. After the resetting of the extrusion plate 7, the extrusion plate 7 is away from the ceiling, so the extrusion plate 7 loses the extrusion effect of the ceiling, so that it is easy to disassemble the exhaust fan without damaging the ceiling.

[0027] In the present solution, a connecting plate 40 is fixedly connected to the side of the shell 1. By setting the connecting plate 40 on the side of the shell 1, an installation method of the exhaust fan is added, and the exhaust fan can be fixed on the wall. An anti-slip groove is provided on the outer side of the handle 38. The anti-slip groove is provided to increase the friction of the handle 38, thereby facilitating the rotation of the handle 38 and facilitating the movement of the handle 38. An anti-slip pad is provided at the bottom end of the extrusion plate 7. The anti-slip pad is provided to increase the friction between the extrusion plate 7 and the ceiling, thereby improving the stability of the exhaust fan installation.

[0028] In this solution, the end of the moving block 20 is fixedly connected to a second spring 39 fixedly connected to the connecting plate 29. Through the setting of the second spring 39, the second spring 39 is squeezed when the threaded column 24 moves, and the reaction force of the second spring 39 on the threaded column 24 can limit the threaded column 24.
