Thus, features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features.

[0034] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" 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 a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The following is combined with Figures 1 to 8 The technical solution of the present invention is further illustrated by specific implementation methods.

[0036] A ventilation fan applied to an integrated ceiling comprises a ventilation fan 10 and four mounting structures 20, wherein the ventilation fan 10 is mounted on the integrated ceiling through the mounting structures 20, and the integrated ceiling comprises a plurality of keels 9 arranged at intervals;

[0037] The ventilation fan 10 includes a square shell 11, and the mounting structure 20 includes a mounting frame 21 and a mounting clip 22. The mounting clip 22 is installed at the bottom of the mounting frame 21, and the mounting frame 21 is snap-mounted on the shell 11. The mounting clip 22 is snap-mounted on the keel 9. The four mounting frames 21 are respectively installed at the four corners of the shell 11, and the two mounting clips 22 on the same side are installed on the same keel 9.

[0038] The present invention designs an independent mounting structure 20 so that the ventilating fan 10 can be installed on the integrated ceiling without any modification or drilling, which not only protects the integrity of the ventilating fan 10 but also avoids performance loss or safety hazards that may be caused by modification.

[0039] Each mounting structure 20 includes a mounting frame 21 and a mounting buckle 22, and the four mounting structures 20 are respectively mounted at the four corners of the ventilating fan housing 11. This layout helps to evenly distribute the weight and force of the ventilating fan 10, thereby enhancing the structural stability and safety of the ventilating fan 10 on the integrated ceiling. The mounting frame 21 is snap-mounted to the housing 11 of the ventilating fan, and the mounting buckle 22 is snap-mounted to the keel 9 of the integrated ceiling. This design greatly simplifies the installation process. There is no need to use a large number of screws for fixing. You only need to snap the mounting structure 20 into the keel 9, thereby saving installation time and labor costs.

[0040] Since the mounting structure 20 is designed independently of the ventilating fan 10, it can be applied to ventilating fans 10 of various specifications and models. As long as the housing shape and size of the ventilating fan 10 meet the requirements, it can be conveniently installed on the integrated ceiling through the mounting structure 20. This improves the versatility and flexibility of the ventilating fan 10.

[0041] Since the ventilation fan 10 is conveniently fixed to the keel 9 of the integrated ceiling through the mounting structure 20, when the ventilation fan 10 needs to be maintained or replaced, it can be easily disassembled and reinstalled without disassembling the entire integrated ceiling, thereby saving maintenance costs and time.

[0042] In summary, the present invention effectively improves the installation flexibility, compatibility, structural stability and safety of the ventilation fan 10 in an integrated ceiling environment by designing an independent installation structure 20, while facilitating subsequent maintenance and replacement, and has important practical application value.

[0043] Further, the housing 11 includes four side walls 111 and four mounting flanges 112, the four side walls 111 form a square, one mounting flange 112 is arranged at the bottom of one side wall 111, the mounting flange 112 extends toward the outside of the housing 11, and the four mounting frames 21 are respectively installed at both ends of two oppositely arranged mounting flanges 112;

[0044] The mounting frame 21 includes a horizontal base plate 211, two limiting plates 212 and a clamping block 213; the horizontal base plate 211 is horizontally extended, and the two limiting plates 212 are relatively parallelly arranged on both sides of the top of the horizontal base plate 211 to form a limiting portion 2101; the clamping block 213 includes a vertical plate 2131 and a horizontal plate 2132, the vertical plate 2131 is vertically arranged on the top surface of the horizontal base plate 211, the horizontal plate 2132 is arranged on the top of the vertical plate 2131, the horizontal plate 2132 is perpendicular to the vertical plate 2131, the horizontal plate 2132 extends toward the direction of the limiting portion 2101, and the clamping block 213 and the horizontal base plate 211 form a clamping portion 2103; the bottom of the end of the horizontal base plate 211 away from the limiting plate 212 is a buckle mounting portion 2104, and the buckle mounting portion 2104 is used to install the mounting buckle 22;

[0045] When the mounting frame 21 is connected to the shell 11, the top surface of the horizontal base plate 211 abuts against the bottom surface of the mounting flange 112, and the two limit plates 212 respectively abut against the two sides of the mounting flange 112, one limit plate 212 is located inside the shell 11, and the other limit plate 212 is located outside the shell 11, the vertical plate 2131 abuts against one end of the mounting flange 112, and the bottom surface of the horizontal plate 2132 abuts against the top surface of the mounting flange 112, and the buckle mounting portion 2104 is located on the outside of the shell 11, and the mounting buckle 22 provided at the same end of the two relatively arranged mounting flanges 112 is installed on the same keel 9.

[0046] The long plate-like structure of the mounting frame 21, and the limiting portion 2101, the locking portion 2103 and the snap-on mounting portion 2104 arranged along the length direction make the various functional areas of the mounting frame 21 clearer and make the installation process of the mounting frame 21 simpler and faster. The limiting portion 2101 can act on the inner and outer sides of the mounting flange 112 to ensure that the mounting frame 21 and the shell 11 (ventilation fan 10) will not rock relative to each other back and forth; the abutting portion 2103 can abut on one end of the mounting flange 112, and the two mounting frames 21 at both ends of the mounting flange 112 work together to prevent the shell 11 (ventilation fan 10) from moving left and right. This multiple limiting and abutting design significantly improves the stability of the ventilation fan 10 during installation and reduces the risk of loosening due to vibration or external force; finally, after the mounting frame 21 is snap-fitted to the shell 11 (mounting flange 112), the snap-fitting mounting portion 2104 of the mounting frame 21 is located on the outside of the shell 11, and the mounting buckle 22 is installed on the snap-fitting mounting portion 2104 located at the bottom of the mounting frame 21, so that the ventilation fan can be snapped onto the keel 9 of the integrated ceiling through the mounting buckle 22.

[0047] By installing two mounting brackets 21 at the two ends of two mounting flanges 112 disposed opposite to each other, and installing the mounting buckles 22 at the same end of the two mounting flanges 112 disposed opposite to each other on the same keel 9, it not only saves space, but also makes the installation of the ventilating fan 10 on the integrated ceiling more compact and neat, and also improves the stability of the ventilating fan 10 on the integrated ceiling, and enhances its wind pressure resistance and service life. At the same time, this installation method is also convenient for later maintenance and replacement, and reduces the use cost.

[0048] It is worth noting that the mounting flange 112 at the bottom of the housing 11 is not a modified structure of the exhaust fan 10, and the mounting flange 112 extending horizontally outward is commonly present in the outer shell structure of the exhaust fan 10. The mounting flange 112 is used to connect with the ceiling during the installation of a traditional gypsum ceiling or a wooden frame ceiling; or in the installation of an integrated ceiling, the mounting flange 112 is connected to the integrated ceiling by screws.

[0049] Further, the mounting frame 21 is composed of a horizontal base plate 211, two limiting plates 212 and a clamping block 213, forming a multiple limiting and supporting structure. The horizontal base plate 211 provides a stable base, and the two limiting plates 212 limit the mounting flange 112 from both sides (inside and outside), effectively preventing the ventilation fan 10 from moving forward and backward during the installation process. The inverted L-shaped design of the vertical plate 2131 and the horizontal plate 2132 of the clamping block 213 further enhances the fixing effect of the mounting frame 21 on the mounting flange 112, so that the ventilation fan 10 can be more firmly installed on the integrated ceiling.

[0050] The structural design of the mounting frame 21 makes the installation process of the mounting frame 21 and the housing 11 more intuitive and simple. The installer only needs to place the horizontal base plate 211 of the mounting frame 21 on the bottom surface of the mounting flange 112, and then adjust the position of the limit plate 212 and the clamping block 213 so that they fit tightly with the mounting flange 112. This design reduces the complexity and uncertainty of the installation process and improves the convenience and operability of the installation. Please refer to Figure 6 and Figure 7 , Figure 7 B-1, B-2 and B-3 are Figure 6 Schematic diagram of the assembly process of the mounting frame 21 and the shell 11 at B in the middle. Specifically, as shown in B-1, the mounting frame 21 moves upward from the bottom of the mounting flange 112, so that the two limiting plates 212 of the limiting portion 2101 are respectively located at the front and rear (inside and outside) sides of the mounting flange 112, so that the mounting frame 21 and the shell 11 are in the state shown in B-2; as shown by the arrow in B-2, the mounting frame 21 is moved to the left, so that the clamping block 213 moves to the state shown in B-3, at this time, the vertical plate 2131 of the clamping block abuts against the end of the mounting flange 112, and the bottom surface of the horizontal plate 2132 abuts against the top surface of the mounting flange 112. The state of B-3 belongs to the installation connection between the mounting frame 21 and the shell 11. Since the clamping portion 2103 is buckled on the end, top surface and bottom surface of the mounting flange 112, the mounting frame 21 cannot be separated from the shell 11 at the bottom, ensuring the stability and firmness of the connection between the mounting frame 21 and the shell 11. When removing, the mounting frame 21 only needs to slide rightward relative to the mounting protrusion 112 (shell 11) to disengage the mounting protrusion 112 from the buckle of the abutting portion 2103, and the mounting frame 21 can move downward and disengage from the mounting connection with the shell 11.

[0051] Further, by refining the structure of the mounting frame 21, such as the horizontal base plate 211 abutting against the bottom surface of the mounting flange 112, the limiting plate 212 limiting the two sides of the mounting flange 112, the vertical plate 2131 abutting against one end of the mounting flange 112, and the bottom surface of the horizontal plate 2132 abutting against the top surface of the mounting flange 112, high precision is ensured during the installation process. This precise installation positioning helps to reduce installation errors and improve the use effect of the ventilation fan.

[0052] Furthermore, the two ends of the mounting protrusion 112 are respectively provided with a frame mounting hole 1121, and the horizontal base plate 211 is provided with two mounting holes 2110, one of the mounting holes 2110 is located at the limiting portion 2101, and the other mounting hole 2110 is located at the buckle mounting portion 2104;

[0053] The mounting frame 21 is connected to the housing 11 through a fastener passing through the mounting hole 2110 located at the limiting portion 2101 and the frame mounting hole 1121;

[0054] The mounting frame 21 is connected to the mounting buckle 22 via a fastener passing through a mounting hole 2110 located on the buckle mounting portion 2104 .

[0055] By respectively providing frame mounting holes 1121 at both ends of the mounting flange 112 and providing two mounting holes 2110 (one at the limiting portion 2101 and the other at the buckle mounting portion 2104) on the horizontal base plate 211, the mounting frame 21 can be firmly connected to the housing 11 and the mounting buckle 22 through fasteners (such as screws). This not only improves the stability and reliability of the installation, but also ensures the stability and safety of the ventilating fan 10 after installation.

[0056] By respectively setting frame mounting holes 1121 at both ends of the mounting flange 112, and setting corresponding mounting holes 2110 on the horizontal substrate 211, and then using fasteners (such as screws) to pass through the mounting holes 2110 located at the limiting portion 2101 and the frame mounting holes 1121, it can be ensured that the connection between the mounting frame 21 and the shell 11 is more secure. This design, based on the original connection method of the snap-on structure, cooperates with the locking of the fasteners to further strengthen the connection strength between the mounting frame 21 and the shell 11, effectively prevent the mounting frame 21 from loosening or falling off during the installation process, and improve the overall stability of the ventilation fan.

[0057] A mounting hole 2110 is also provided on the horizontal base plate 211 at the position of the clip mounting portion 2104, so that the mounting frame 21 and the mounting clip 22 are connected by fasteners (such as screws), which can ensure the rapid assembly of the mounting structure 20 and ensure the compatibility of mounting clips 22 of different sizes (different mounting clips 22 are used for different sizes of keels) with the mounting frame 21.

[0058] Furthermore, the material of the mounting frame 21 is plastic.

[0059] Plastic material has the characteristics of light weight and high strength, which makes the mounting frame 21 relatively light while maintaining sufficient strength. This is not only conducive to reducing the overall weight of the ventilating fan and reducing the load-bearing pressure on the integrated ceiling, but also helps to improve the convenience of installation and disassembly. In addition, plastic material has good insulation properties, which makes the mounting frame 21 have certain advantages in electrical safety. During the operation of the ventilating fan 10, the plastic mounting frame 21 can effectively isolate the current and prevent electrical failures or electric shock accidents.

[0060] Furthermore, the mounting buckle 22 includes a buckle plate 221 and two elastic arms 222, and the two elastic arms 222 are respectively arranged at two ends of the bottom of the buckle plate 221;

[0061] The top end of the elastic arm 222 is connected to the buckle plate 221, the middle part of the elastic arm 222 is protruding with a buckle portion 2221, the bottom end of the elastic arm 222 is provided with a handle portion 2222, and the handle portion 2222 extends in the opposite direction of the protruding buckle portion 2221, and the buckle portions 2221 of the two elastic arms 222 are arranged opposite to each other.

[0062] The mounting buckle 22 adopts a structural design of a buckle plate 221 and two elastic arms 222. The buckle portion 2221 of the elastic arm 222 can be firmly clamped on the keel 9 or other fixed structures, effectively preventing the ventilation fan from loosening or falling off during the installation process. This design improves the stability of the connection between the ventilation fan and the integrated ceiling, ensuring the stable operation of the ventilation fan 10. A handle portion 2222 is provided at the bottom end of the elastic arm 222, which is convenient for the installer to operate easily during the installation or disassembly process. By pulling the handle portion 2222, the elastic arm 222 can be elastically deformed, thereby conveniently clamping in or out of the keel 9. This design simplifies the installation steps and improves the convenience and efficiency of installation.

[0063] Furthermore, the buckle plate 221 is provided with a buckle mounting hole 2211 , and the mounting buckle 22 is connected to the mounting frame 21 through a fastener passing through the buckle mounting hole 2211 .

[0064] By providing the buckle mounting hole 2211 on the buckle plate 221 and using fasteners to connect the mounting buckle 22 to the mounting frame 21, the accuracy and stability during the installation process can be ensured. The use of fasteners provides a stable fixing force to prevent the mounting buckle 22 from shifting or loosening during the installation process, thereby improving the overall stability of the ventilator.

[0065] The mounting buckle 22 is connected to the mounting frame 21 by fasteners (such as screws) to form a more compact and stable structural whole. This design can not only enhance the wind pressure resistance and earthquake resistance of the ventilation fan, but also reduce the noise and vibration problems caused by structural looseness, thereby improving the reliability and service life of the product.

[0066] Furthermore, the ventilation fan 10 also includes a cover plate 12 and two torsion springs 13. The two torsion springs 13 are symmetrically arranged on the cover plate 12. The cover plate 12 is buckled to the lower part of the shell 11 through the torsion springs 13. The bottom of the cover plate 12 is flush with the bottom of the integrated ceiling.

[0067] The cover plate 12 is designed to cover the lower part of the ventilating fan housing 11 and be flush with the bottom of the integrated ceiling, thereby achieving a seamless connection between the ventilating fan and the integrated ceiling visually and improving the overall aesthetics and coordination.

[0068] The cover plate 12 is buckled to the lower part of the housing 11 by the torsion spring 13, which increases the stability of the ventilation fan structure and prevents the cover plate 12 from being easily opened due to vibration or external force. The elasticity and resilience of the torsion spring 13 ensure the stability of the cover plate 12 when closed, and improve the overall durability and safety of the ventilation fan 10.

[0069] Furthermore, the torsion spring 13 includes a torsion spring body 131 and two torsion arms 132, the torsion spring body 131 is a columnar spring structure, the two torsion arms 132 are arranged at both ends of the torsion spring body 131, the torsion spring body 131 is installed on the top surface of the cover plate 12, and the two torsion arms 132 extend upwardly and tilted toward each other;

[0070] The housing 11 is provided with a slot 113 , and the slot 113 is used to accommodate an end of the torsion arm 132 away from the torsion spring body 131 .

[0071] The design of the torsion spring 13 makes the connection between the cover plate 12 and the housing 11 more stable. The torsion spring body 131 is a columnar spring structure that provides a stable elastic force, while the two torsion arms 132 extend upward and tilt toward each other. During installation, the two torsion arms 132 extending toward each other are relatively close to each other, and the ends of the two torsion arms 132 are inserted into the slots 113 of the housing; after the torsion arms 132 are released, the torsion arms 132 are pressed against the slots 113 under the action of elastic force, effectively preventing the cover plate 12 from loosening or falling off under vibration or external force.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way.
