Description

Technical Field

[0001] The present invention relates to the technical field of ceiling exhaust fan installation, and specifically provides an energy-saving ceiling exhaust fan that is convenient for disassembly and assembly. Background Art

[0002] An exhaust fan is a type of air conditioning appliance that drives air flow by an electric motor to rotate the fan blades, enabling the exchange of indoor and outdoor air. It is also known as a ventilation fan. The purpose of exhaust is to remove the dirty air indoors, regulate temperature and humidity, and is widely used in homes and public places. The exhaust fan is also called a negative pressure fan, negative pressure blower, etc. By using air convection, the indoor environment can be kept in a negative pressure state, forming a suction force that continuously sucks in outdoor air and discharges the stuffy indoor air, thereby achieving the effects of ventilation and cooling.

[0003] Currently, with the improvement of living quality, exhaust fans are widely used in construction sites, large shopping malls, and home environments. Ceiling-mounted exhaust fans are commonly used to ventilate indoor air. In the prior art, there are two common methods for installing exhaust fans. The first is to fix the exhaust fan to the ceiling through fixing screws. However, when installing and disassembling, tools need to be carried to screw the fixing screws one by one, which is inconvenient during installation. The second is to directly clamp the exhaust fan on the ceiling through spring pieces. Although the installation is simple, when disassembling, it is necessary to pull the exhaust fan downward with force, which is likely to damage the ceiling. Therefore, both of the above installation methods for exhaust fans have certain defects. For this reason, we propose an energy-saving ceiling exhaust fan that is convenient for disassembly and assembly. Summary of the Invention

[0004] The purpose of the present invention is to provide an energy-saving ceiling exhaust fan that is convenient for disassembly and assembly, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An energy-saving ceiling exhaust fan that is convenient for disassembly and assembly, including a housing, an installation component, and a quick-release component. A check valve is installed on the housing, and a wind wheel is installed inside the housing. A fixing piece fixedly connected to the housing is fixedly connected to the wind wheel. The installation component includes four fixing frames, and the four fixing frames are respectively symmetrically and fixedly installed in pairs at the bottom end of the housing. An extrusion plate is slidably connected to the fixing frame. The installation component installs the housing and the wind wheel on the ceiling through the extrusion action of the extrusion plate. The quick-release component is arranged in cooperation with the installation component, and the quick-release component is used to drive the extrusion plate to reset. Through the settings of the installation component and the quick-release component, the quick installation and disassembly of the exhaust fan can be realized.

[0006] Preferably, the installation assembly includes four fixing seats fixedly connected to the housing. The four fixing seats are respectively installed at the top positions of the four fixing frames. A sleeve is fixedly connected to the fixing seat. A tension spring is fixedly connected inside the sleeve. The end of the tension spring is fixedly connected to a sliding block slidably connected to the sleeve. The end of the sliding block is fixedly connected to a pressing column fixedly connected to the pressing plate. The pressing column is slidably connected to the fixing frame. The top of the sleeve is communicated with a connecting head. The end of the connecting head is communicated with a connecting pipe extending into the housing. The end of the connecting pipe is connected with a pressure control member, which is convenient for quickly installing the exhaust fan.

[0007] Preferably, the pressure control member includes four supporting seats fixedly connected to the housing. The four supporting seats are respectively and symmetrically fixed in pairs inside the housing. A pressure control pipe is fixedly connected to the supporting seat. The end of the pressure control pipe is communicated with a connecting pipe communicated with the connecting pipe. A moving block is slidably connected inside the pressure control pipe. A moving member is installed on the moving block, which is convenient for controlling the air pressure inside the sleeve.

[0008] Preferably, the moving member includes four connecting seats fixedly connected to the housing. The four connecting seats are arranged in pairs symmetrically. Two connecting seats on the same side of the housing are rotatably connected with a threaded pipe. Threaded columns are respectively screwed at both ends of the threaded pipe. The thread directions of the two threaded columns at both ends of the threaded pipe are opposite. The end of the threaded column is fixedly connected to a moving column fixedly connected to the moving block, which is convenient for driving the moving block to move and squeezing the air pressure inside the pressure control pipe into the sleeve.

[0009] Preferably, the quick-release assembly includes a sliding sleeve installed inside the pressure control pipe. The sliding sleeve is slidably connected to the pressure control pipe. A first through hole is opened on the sliding sleeve. A second through hole adapted to the first through hole is opened on the pressure control pipe. The position of the second through hole corresponds to the position of the sliding sleeve. A connecting piece is fixedly connected inside the sliding sleeve. Several air outlet holes are opened on the connecting piece. One end of the connecting piece is fixedly connected to a first spring fixedly connected to the pressure control pipe. The other end of the connecting piece is connected with a pushing member extending into the threaded pipe. The pushing member is used to drive the sliding sleeve to move so that the first through hole and the second through hole correspond, and the exhaust fan can be quickly disassembled.

[0010] Preferably, the pushing member includes a sliding column fixedly connected to the connecting piece. The sliding column extends into the threaded tube, and the sliding column is slidably connected to the moving block, the moving column, and the threaded column. A fixing block is fixedly connected to the end of the sliding column, a connecting column is fixedly connected to the fixing block, a movable block slidably connected to the threaded tube is fixedly connected to the outer side surface of the connecting column. A sliding groove adapted to the movable block is formed in the threaded tube, and a handle slidably connected to the threaded tube is fixedly connected to the end of the connecting column. The sliding sleeve is driven to move by the action of the pushing member, so that the first through hole and the second through hole are aligned.

[0011] Preferably, a second spring fixedly connected to the connecting piece is fixedly connected to the end of the moving block. By providing the second spring, when the threaded column moves, the second spring is compressed. The reaction force of the second spring on the threaded column can limit the threaded column.

[0012] Preferably, a connecting plate is fixedly connected to the side surface of the housing. By arranging the connecting plate on the side surface of the housing, a mounting method of the exhaust fan is increased, and the exhaust fan can be fixed on the wall surface.

[0013] Preferably, anti-slip grooves are formed in the outer side surface of the handle. By providing the anti-slip grooves, the friction of the handle is increased, so that it is convenient to drive the handle to rotate and move the handle.

[0014] Preferably, an anti-slip pad is provided at the bottom end of the pressing plate. By providing the anti-slip pad, the friction between the pressing plate and the ceiling is increased, so that the installation stability of the exhaust fan is improved.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] An energy-saving ceiling exhaust fan that is easy to disassemble and assemble provided by the present invention. When installing the exhaust fan, place the exhaust fan inside the ceiling top, clamp the fixing frame at the side position of the ceiling, and place the pressing plate at the top of the ceiling. During the installation process, rotate the threaded tube. Due to the action of the threaded tube, the threaded column moves. The movement of the threaded column drives the moving block to move. The movement of the moving block squeezes the air pressure inside the pressure control tube into the sleeve. When the air pressure inside the sleeve increases, the sliding block moves downward due to the action of the air pressure. The action of the sliding block causes the pressing column to drive the pressing plate to move. Therefore, through the action of the pressing plate, the ceiling is squeezed, making the ceiling clamped between the fixing frame and the pressing plate, thereby fixing the exhaust fan on the ceiling. When disassembling, due to the action of the quick-release component, the pressure control tube is in an unsealed state. At this time, the sliding block is reset due to the action of the tension spring inside the sleeve. Therefore, the pressing plate will move away from the ceiling, making it easy to remove the exhaust fan. By providing an installation component, the exhaust fan can be installed without carrying any tools during installation, and the exhaust fan can be quickly disassembled through the action of the quick-release component without causing any damage to the ceiling. Therefore, the problem of defects in the installation of exhaust fans in the prior art is solved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-10 , the present invention provides a technical solution: an energy-saving ceiling exhaust fan that is easy to disassemble and assemble, including an outer shell 1, an installation component 5, and a quick-release component 8. A check valve 2 is installed on the outer shell 1, and a wind wheel 3 is installed inside the outer shell 1. A fixing piece 4 fixedly connected to the wind wheel 3 is fixedly connected to the outer shell 1; the installation component 5 includes four groups of fixing brackets 6, and the four groups of fixing brackets 6 are respectively symmetrically and fixedly installed in pairs at the bottom end position of the outer shell 1. An extrusion plate 7 is slidably connected to the fixing bracket 6, and the installation component 5 installs the outer shell 1 and the wind wheel 3 on the ceiling through the extrusion action of the extrusion plate 7; the quick-release component 8 is arranged in cooperation with the installation component 5, and the quick-release component 8 is used to drive the extrusion plate 7 to reset.

[0030] In this solution, when installing the exhaust fan, place the exhaust fan inside the ceiling top, clamp the fixing bracket 6 on the side of the ceiling, and place the extrusion plate 7 on the top of the ceiling. During the installation process, drive the extrusion plate 7 to squeeze the ceiling through the action of the installation component 5, so that the ceiling is clamped between the fixing bracket 6 and the extrusion plate 7, thereby fixing the exhaust fan on the ceiling. When disassembling, through the action of the quick-release component 8, the extrusion plate 7 can be quickly separated from the ceiling, facilitating the disassembly of the exhaust fan.

[0031] The installation component 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. 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 that is slidably connected to the sleeve 10. The end of the sliding block 12 is fixedly connected to a pressing column 13 that is fixedly connected to the pressing plate 7. The pressing column 13 is slidably connected to the fixing frame 6. The top of the sleeve 10 is communicated with a connector 14. The end of the connector 14 is communicated with a connecting pipe 15 that extends into the housing 1. The end of the connecting pipe 15 is connected to a pressure control member 16; the pressure control member 16 includes four groups of support seats 17 fixedly connected to the housing 1. The four groups of support seats 17 are respectively and symmetrically fixed in pairs inside the housing 1. A pressure control pipe 18 is fixedly connected to the support seat 17. The end of the pressure control pipe 18 is communicated with a communicating pipe 19 that is communicated with the connecting pipe 15. A moving block 20 is slidably connected inside the pressure control pipe 18. 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 housing 1. The four groups of connecting seats 22 are arranged in pairs symmetrically. Two groups of connecting seats 22 on the same side of the housing 1 are rotatably connected with a threaded pipe 23. Threaded columns 24 are screwed at both ends of the threaded pipe 23. The threading directions of the two groups of threaded columns 24 at both ends of the threaded pipe 23 are opposite. The end of the threaded column 24 is fixedly connected to a moving column 25 that is fixedly connected to the moving block 20, which is convenient for driving the moving block 20 to move and squeezing the air pressure inside the pressure control pipe 18 into the sleeve 10.

[0032] In this solution, during the installation process, by rotating the threaded pipe 23, the rotation of the threaded pipe 23 causes the threaded column 24 to move. When the threaded column 24 moves, the moving column 25 will drive the moving block 20 to move. The gas inside the pressure control pipe 18 is squeezed into the communicating pipe 19 through the movement of the moving block 20. Through the action of the communicating pipe 19, the connecting pipe 15, and the connector 14, the gas inside the pressure control pipe 18 is squeezed into the sleeve 10, increasing the air pressure inside the sleeve 10. Through the action of the air pressure, the sliding block 12 moves. The movement of the sliding block 12 drives the pressing column 13 and the pressing plate 7 to move. Through the action of the pressing plate 7, the exhaust fan is installed on the ceiling.

[0033] In this solution, during the movement of the sliding block 12, the tension spring 11 will be pulled into a stretched state. Therefore, through the action of the tension spring 11, it is convenient for the sliding block 12 to reset, thus facilitating the rapid disassembly of the exhaust fan in the later stage.

[0034] The quick-release component 8 includes a sliding sleeve 26 installed inside the pressure control pipe 18. The sliding sleeve 26 is slidably connected to the pressure control pipe 18, and a first through hole 27 is formed in the sliding sleeve 26. A second through hole 28 adapted to the first through hole 27 is formed in the pressure control pipe 18. 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. A plurality of groups of air outlet holes 30 are formed in the connecting piece 29. One end of the connecting piece 29 is fixedly connected to a first spring 31 fixedly connected to the pressure control pipe 18, and the other end of the connecting piece 29 is connected to a pushing member 32 extending into the threaded pipe 23. The pushing member 32 is used to drive the sliding sleeve 26 to move so that the first through hole 27 and the second through hole 28 are aligned. The pushing member 32 includes a sliding column 33 fixedly connected to the connecting piece 29. The sliding column 33 extends into the threaded pipe 23, and the sliding column 33 is slidably connected to the moving block 20, the moving column 25, and the threaded column 24. A fixing block 34 is fixedly connected to the end of the sliding column 33. A connecting column 35 is fixedly connected to the fixing block 34. An active block 36 slidably connected to the threaded pipe 23 is fixedly connected to the outer side of the connecting column 35. A sliding groove 37 adapted to the active block 36 is formed in the threaded pipe 23, and a handle 38 slidably connected to the threaded pipe 23 is fixedly connected to the end of the connecting column 35.

[0035] In this solution, during disassembly, the two handles 38 on the threaded pipe 23 are moved towards both ends. The movement of the handles 38 causes the connecting column 35 to drive the fixing block 34 to move. The movement of the fixing block 34 causes the sliding column 33 to move. The movement of the sliding column 33 drives the connecting piece 29 to move. The movement of the connecting piece 29 causes the sliding sleeve 26 to move. When the sliding sleeve 26 moves, the first through hole 27 and the second through hole 28 are aligned. After the first through hole 27 and the second through hole 28 are aligned, the pressure control pipe 18 is in an unsealed state. At this time, the air pressure inside the sleeve 10 is discharged. The action of the tension spring 11 can pull the sliding block 12 to reset. The reset of the sliding block 12 causes the extrusion column 13 and the extrusion plate 7 to move in the reverse direction and reset. After the extrusion plate 7 is reset, the extrusion plate 7 moves away from the ceiling. Therefore, the extrusion plate 7 loses the extrusion effect of the ceiling, making it convenient to disassemble the exhaust fan without damaging the ceiling.

[0036] Working principle: When installing the exhaust fan, place the exhaust fan inside the ceiling top, clamp the fixing bracket 6 at the side position of the ceiling, and place the pressing plate 7 at the top of the ceiling. During the installation process, by rotating the threaded tube 23, the rotation of the threaded tube 23 causes the threaded column 24 to move. When the threaded column 24 moves, it will cause the moving column 25 to drive the moving block 20 to move. Through the movement of the moving block 20, the gas inside the pressure control tube 18 is squeezed 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 control tube 18 is squeezed into the sleeve 10, increasing the air pressure inside the sleeve 10. Through the action of the air pressure, the sliding block 12 moves. The movement of the sliding block 12 drives the extrusion column 13 and the pressing plate 7 to move. Through the action of the pressing plate 7, the exhaust fan is installed on the ceiling. During installation, the exhaust fan can be quickly installed without carrying any tools. And during the installation process, the sliding sleeve 26 does not move. Through the action of the sliding sleeve 26, the second through hole 28 can be sealed, making the pressure control tube 18 in a sealed state. Therefore, all the air pressure is squeezed into the sleeve 10. And when disassembling, move the two groups of handles 38 on the threaded tube 23 towards both ends. The movement of the handles 38 causes the connecting column 35 to drive the fixing block 34 to move. The movement of the fixing block 34 causes the sliding column 33 to move. The movement of the sliding column 33 drives the connecting piece 29 to move. The movement of the connecting piece 29 causes the sliding sleeve 26 to move. When the sliding sleeve 26 moves, the first through hole 27 and the second through hole 28 are aligned. After the first through hole 27 and the second through hole 28 are aligned, the pressure control tube 18 is in an unsealed state. At this time, the air pressure inside the sleeve 10 is discharged. Through the action of the tension spring 11, the sliding block 12 can be pulled back to its original position. The reset of the sliding block 12 causes the extrusion column 13 and the pressing plate 7 to move in the reverse direction and reset. After the pressing plate 7 is reset, the pressing plate 7 moves away from the ceiling. Therefore, the pressing plate 7 loses the squeezing effect of the ceiling, making it easy to disassemble the exhaust fan without damaging the ceiling.

[0037] In this solution, a connecting plate 40 is fixedly connected to the side of the housing 1. By setting the connecting plate 40 on the side of the housing 1, a new installation method for the exhaust fan is added, enabling the exhaust fan to be fixed on the wall. Anti-slip grooves are provided on the outer side of the handle 38. Through the setting of the anti-slip grooves, the friction of the handle 38 is increased. Therefore, it is convenient to drive the handle 38 to rotate and move the handle 38. A non-slip pad is provided at the bottom of the pressing plate 7. Through the setting of the non-slip pad, the friction between the pressing plate 7 and the ceiling is increased. Therefore, the installation stability of the exhaust fan is improved.

[0038] In this solution, a second spring 39 fixedly connected to the connecting piece 29 is fixedly connected to the end of the moving block 20. Through the arrangement of the second spring 39, when the threaded column 24 moves, the second spring 39 is squeezed, and the reaction force of the second spring 39 on the threaded column 24 can play a role in limiting the threaded column 24.
