[0036] The following is for reference. Figure 1 and Figure 2 This invention describes a motor fixing structure according to an embodiment of the present invention.

[0037] like Figure 1 and Figure 2As shown, the motor fixing structure according to an embodiment of the present utility model includes a smoke hood 100, a fan 200, a motor 300, and a connecting component 400.

[0038] Reference Figure 3 , Figure 4 A smoke hood 100 is located above the burner. The upper side of the smoke hood 100 has a mounting plate 110 with an air intake hole 111. A fan 200 covers the air intake hole 111. The fan 200 includes a housing 210 and a fan wheel 220. The fan wheel 220 is located inside the housing 210. The airflow inside the smoke hood 100 can be drawn into the housing 210 through the fan wheel 220 and then discharged outward. A motor 300 is connected to the outside of the housing 210. The motor 300 has a motor output shaft 310, which is connected to the fan wheel 220. A motor connecting plate 320 is provided on the outside of the motor 300. A connecting assembly 400 is connected between the motor connecting plate 320 and the outer wall of the housing 210. The connecting assembly 400 includes a shock-absorbing sleeve 410. The upper side of the shock-absorbing sleeve 410 abuts against the lower side of the motor connecting plate 320, and the lower side of the shock-absorbing sleeve 410 abuts against the upper side of the housing 210.

[0039] For example, such as Figure 1 and Figure 2 As shown, the fume hood 100 is located above the burner, and the exhaust gas generated by the burner is collected in the fume hood 100. The upper side of the fume hood 100 has a mounting plate 110, and the mounting plate 110 has air vents 111. (Refer to...) Figure 3 , Figure 4 The fan 200 is fitted onto the air intake vent 111. The fan 200 includes a housing 210 and a fan wheel 220, with the fan wheel 220 located inside the housing 210. Airflow within the smoke hood 100 is drawn into the housing 210 through the fan wheel 220 and then discharged outwards, thus achieving smoke extraction. The motor 300 is connected to the outside of the housing 210. The motor 300 has a motor output shaft 310, which is connected to the fan wheel 220, allowing the motor 300 to drive the fan wheel 220 to rotate. A motor connecting plate 320 is provided on the outside of the motor 300. A connecting assembly 400 is connected between the motor connecting plate 320 and the outer wall of the housing 210. The connecting assembly 400 includes a shock-absorbing sleeve 410, with the upper side of the shock-absorbing sleeve 410 pressing against the lower side of the motor connecting plate 320 and the lower side of the shock-absorbing sleeve 410 pressing against the upper side of the housing 210. The shock-absorbing sleeve 410 can buffer the vibration transmission between the motor 300 and the fan 200.

[0040] In actual operation, the burner operates, and simultaneously the motor 300 drives the impeller 220 of the fan 200 to rotate. The exhaust gas generated by the burner forms an airflow that first gathers in the fume hood 100. Then, the airflow within the fume hood 100 is drawn into the casing 210 through the duct 111 and discharged outwards, thus achieving the exhaust function.

[0041] During the aforementioned operation, the motor 300 and the fan 200 will vibrate. This vibration is damped by the shock-absorbing sleeve 410, effectively reducing resonance caused by the vibration of the motor 300 and the fan 200. This effectively reduces the noise generated by the motor 300 and the fan 200 during operation, achieving a quiet operation.

[0042] In some embodiments of this utility model, a housing through-shaft hole 212 is provided on the housing 210, so that the motor output shaft 310 of the motor 300 can pass through the housing through-shaft hole 212 and extend into the housing 210 to connect with the impeller 220.

[0043] In some embodiments of this utility model, reference is made to Figure 6 , Figure 7 A connecting post 500 is provided on the upper side of the housing 210, and a connecting post slot 510 is provided on the side wall of the connecting post 500. A shock-absorbing sleeve retaining edge 411 is provided on the lower side of the inner side wall of the shock-absorbing sleeve 410. The connecting post slot 510 can retain the shock-absorbing sleeve retaining edge 411.

[0044] On the upper part of the housing 210, connecting posts 500 are designed as a connection structure. These connecting posts 500 are not only firmly fixed to the housing, but also serve as a structure for fixing and connecting the shock-absorbing sleeve 410. Specifically, the connecting post slot 510 on the connecting post 500 engages with the shock-absorbing sleeve retaining edge 411 on the lower end of the inner wall of the shock-absorbing sleeve 410. This structural design aims to ensure that the shock-absorbing sleeve 410 can fit tightly with the housing 210. When the connecting post slot 510 and the shock-absorbing sleeve retaining edge 411 engage, the shock-absorbing sleeve retaining edge 411 can be effectively secured, thereby ensuring the stability and shock absorption effect of the shock-absorbing sleeve 410 on the housing 210. This design not only improves the connection strength of the shock-absorbing sleeve 410 to the housing 210, but also enhances the stability and durability of the shock-absorbing sleeve 410 in various working environments.

[0045] In some embodiments of this utility model, reference is made to Figure 4 , Figure 5 The connection between the housing 210 and the connecting column 500 can be either detachable or integrally formed.

[0046] In some embodiments of this utility model, reference is made to Figure 5 , Figure 7 The connecting column 500 is provided with a connecting column support boss 520, and the connecting column slot 510 is located above the connecting column support boss 520. The lower end of the shock-absorbing sleeve 410 can abut against the upper surface of the connecting column support boss 520 to provide support for the shock-absorbing sleeve 410.

[0047] A connecting column support boss 520 is designed on the connecting column 500. This boss structure is located at a specific corresponding position on the connecting column 500 to provide additional support and stability for the shock-absorbing sleeve 410. Above the connecting column support boss 520 is a connecting column slot 510, which facilitates the assembly and connection of the shock-absorbing sleeve 410. The lower end of the shock-absorbing sleeve 410 is designed to hold against the upper surface of the connecting column support boss 520. This design not only enhances the overall stability of the shock-absorbing sleeve 410 but also absorbs and reduces the impact of vibration or shock, ensuring the stability and durability of the entire structure.

[0048] In some embodiments of this utility model, a motor connection plate 320 is provided with a motor connection plate mounting hole 321, and a shock absorber sleeve groove 412 is provided on the upper side of the outer side wall of the shock absorber sleeve 410. The upper side of the shock absorber sleeve 410 is inserted into the motor connection plate mounting hole 321, and the shock absorber sleeve groove 412 can lock the hole wall of the motor connection plate mounting hole 321.

[0049] Specifically, in the motor connecting plate 320 structure on the outside of the motor 300, a motor connecting plate mounting hole 321 for connecting the shock-absorbing sleeve 410 is formed on its surface. The upper part of the outer wall of the shock-absorbing sleeve 410 is designed to have at least one shock-absorbing sleeve slot 412. Thus, during actual assembly, the upper part of the shock-absorbing sleeve 410 can be inserted into the motor connecting plate mounting hole 321, and the shock-absorbing sleeve slot 412 can effectively lock the hole wall of the motor connecting plate mounting hole 321, thereby ensuring a stable connection between the shock-absorbing sleeve 410 and the motor 300. This design not only improves the reliability of the shock-absorbing sleeve 410 connection but also absorbs and reduces vibrations generated by the operation of the motor 300, further protecting the stability and lifespan of the motor 300.

[0050] In some embodiments of this utility model, a connecting bottom post 530 is provided on the lower side of the connecting post 500, and a connecting post mounting hole 211 is provided on the upper side of the housing 210. The connecting bottom post 530 is inserted into the connecting post mounting hole 211 to ensure that the connecting post 500 is sufficiently stable and reliable after being installed on the housing 210.

[0051] In some embodiments of this utility model, the connecting bottom post 530 and the connecting post mounting hole 211 can be connected by snap-fit ​​or by welding to ensure that the connecting post 500 is sufficiently stable on the housing 210.

[0052] In some embodiments of this utility model, the connecting component 400 includes a fixing screw 420, the fixing screw 420 has a screw head 421 on its upper side and a threaded portion 422 on its lower side. The lower side of the screw head 421 can press against the upper end face of the shock-absorbing sleeve 410, and the lower side of the fixing screw 420 passes through the shock-absorbing sleeve 410 and is threadedly connected to the housing 210 through the threaded portion 422, thereby realizing the fixed installation of the connecting component 400.

[0053] The design of the connecting assembly 400 includes the shock-absorbing sleeve 410 and the fixing screw 420 as key components, with the fixing screw 420 used to secure the connecting assembly 400. The fixing screw 420 has a screw head 421 at its upper end, located at the very tip of the screw for easy torque application to tighten it. Below the screw head 421 is the main body of the screw, namely the threaded portion 422, which has a helical pattern for engaging with the threaded hole. During installation, the lower end of the screw head 421 applies pressure, pressing against the upper surface of the shock-absorbing sleeve 410 to ensure it is securely fixed in place. The lower end of the fixing screw 420 passes through the central hole of the shock-absorbing sleeve 410 and continues downward until its threaded portion 422 engages with the threaded hole on the housing 210. This connection method not only ensures the stability of the connection component 400, but also allows for easy disassembly and replacement of components such as the motor 300 and the connection component 400 when needed, improving the convenience of maintenance and repair.

[0054] In some embodiments of this utility model, the motor connecting plate mounting hole 321 has an upper end face and a lower end face of the motor connecting plate mounting hole wall, and the shock-absorbing sleeve groove 412 has an upper end face and a lower end face of the shock-absorbing sleeve groove. When the fixing screw 420 is tightened, the lower side of the screw head 421 presses against the upper end face of the shock-absorbing sleeve 410, and the upper end face of the motor connecting plate mounting hole wall also presses against the upper end face of the shock-absorbing sleeve groove, and the lower end face of the motor connecting plate mounting hole wall also presses against the lower end face of the shock-absorbing sleeve groove, ensuring that the shock-absorbing sleeve 410 and the motor connecting plate 320 are firmly connected.

[0055] In some embodiments of this utility model, the shock-absorbing sleeve 411 has an upper end face and a lower end face of the shock-absorbing sleeve side wall, and the connecting post groove 510 has an upper end face and a lower end face of the connecting post groove. When the fixing screw 420 is tightened, the lower side of the screw head 421 presses against the upper end face of the shock-absorbing sleeve 410, the upper end face of the shock-absorbing sleeve side wall also presses against the upper end face of the connecting post groove, and the lower end face of the shock-absorbing sleeve side wall also presses against the lower end face of the connecting post groove, ensuring that the shock-absorbing sleeve 410 and the connecting post 500 are firmly connected.

[0056] In some embodiments of this utility model, the shock-absorbing sleeve 410 is fitted onto the outside of the fixing screw 420, and the upper side of the connecting column 500 is provided with a connecting column screw hole 540, and the threaded part 422 of the fixing screw 420 is threadedly connected to the connecting column screw hole 540.

[0057] The smoke exhaust fan according to a second aspect embodiment of the present invention includes the motor fixing structure according to the first aspect embodiment of the present invention described above. (Refer to...) Figure 1 , Figure 2The mounting plate 110 has a sloping structure and is inclined from the upper front side to the lower rear side.

[0058] According to the embodiment of this utility model, the exhaust fan, by adopting the aforementioned motor fixing structure, effectively reduces the resonance phenomenon caused by the vibration of the motor 300 and the fan 200. This effectively reduces the noise generated by the motor 300 and the fan 200 during operation, achieving a quiet operation. Furthermore, the inclined design of the mounting plate 110 ensures that after the airflow enters the smoke hood 100, the fan 200 draws in air, and the vertical upward direction of the airflow is angled away from the direction of airflow entering the fan 200. This reduces the impact of smoke on the top of the smoke hood 100, further reducing noise, improving the vibration and noise of the exhaust fan, and enhancing the user experience.

[0059] In some embodiments of this utility model, reference is made to Figure 3 , Figure 4 The smoke hood 100 has a horizontal mounting edge 120 on its lower side. A horizontal mounting edge screw hole 121 is provided on the horizontal mounting edge 120. A smoke hood screw 140 is inserted into the horizontal mounting edge screw hole 121. The smoke hood 100 is fixedly installed by the smoke hood screw 140.

[0060] In some embodiments of this utility model, a side fixing member 130 is provided on the horizontal mounting edge 120. The side fixing member 130 has an "L" shaped structure and has a horizontal part 131 and a vertical part 132. The horizontal part 131 is connected to the horizontal mounting edge 120, and a vertical screw hole 133 is provided on the vertical part 132. A smoke hood screw 140 is also inserted into the vertical screw hole 133.

[0061] In some embodiments of this utility model, a bend 610 and a smoke exhaust pipe 600 are provided on the rear side of the housing 210. The outer side of the housing 210 and the lower side of the smoke exhaust pipe 600 are connected by the bend 610. In this way, the bend 610, which is an inclined pipe section, and the smoke exhaust pipe 600, which is a straight pipe section, cooperate to reduce the resistance of the smoke during exhaust and make the exhaust smoother.

[0062] In some embodiments of this utility model, the elbow 610 is integrally formed by die casting, which ensures higher processing precision, facilitates smoother smoke exhaust, and can meet the needs of water heaters with different structures.

[0063] In some embodiments of this utility model, a top support 150 is provided on the upper side of the smoke hood 100 to assist in fixing the fan 200. In this way, even if the area of ​​the mounting plate 110 is small, it can be ensured that the fan 200 is fixed firmly and reliably on the mounting plate 110.

[0064] In some embodiments of this utility model, a damper plate connecting shaft 621 is provided inside the smoke exhaust pipe 600, and an openable damper plate 620 is provided on the damper plate connecting shaft 621, serving as an opening and closing device for the smoke collection hood 100. When the damper plate 620 blocks the smoke exhaust pipe 600, external airflow or foreign objects cannot pass through the smoke exhaust pipe 600 and enter the smoke collection hood 100. Conversely, when the fan 200 is working, the airflow of the smoke collection hood 100 can pass through the fan 200 and enter the smoke exhaust pipe 600, then force open the damper plate 620 to achieve smoke exhaust.

[0065] Other components and operations of the exhaust fan according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
