However, the bracket assembly has a simple structure and insufficient supporting force. It only connects the motor and the volute assembly. In subsequent use, the motor shakes at high speed, causing mechanical noise. Summary of the invention

[0004] In order to overcome the above-mentioned defects in the prior art, a connection assembly for a gas water heater fan is provided, which is used to support the motor and prevent the motor from shaking and generating mechanical noise.

[0013] Preferably, the fixing piece and the raised plate are both provided with a plurality of fixing holes through which the screws pass.

[0014] Preferably, the mounting plate is assembled on the smoke collecting hood by screws.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] A connection assembly for a gas water heater fan, wherein a first connection piece can firmly connect a motor and a volute to ensure stability and working efficiency therebetween; a second connection piece connects the first connection piece and a smoke hood together to form a complete gas water heater fan system, effectively enhancing the connection stability between the fan, the smoke hood and the motor, avoiding mechanical noise caused by shaking when the motor runs at high speed; reducing vibration and noise generated by the motor when working, and also extending the service life of the gas water heater.

[0017] Furthermore, the lower surface of the support plate and the upper surface of the buckle plate are fitted together, which can ensure a tight connection between the first connecting member and the second connecting member. The fitted surfaces can not only improve the stability of the connection, but also reduce the noise generated by vibration or movement during operation.

[0018] Furthermore, the cooperation of the positioning post and the positioning hole can also increase the firmness of the connection assembly. After assembly, the positioning post passes through the positioning hole to form a fixed connection structure, which can effectively prevent the connection from loosening or falling off due to vibration or external force when the water heater is working.

[0019] Furthermore, the higher positioning column can ensure that during the assembly process, the positioning column can smoothly pass through the positioning hole on the support plate without being blocked by the baffle, which makes the assembly process smoother and more accurate, and improves the assembly efficiency.

[0020] Furthermore, when the lengths of the support plate and the buckle plate are equal, the fit between them will be more uniform, and there will be no assembly imbalance or stability problems caused by one part being too long or too short. This balance ensures that the connection components can be evenly stressed during operation, reducing the stress concentration and damage risks caused by uneven stress.

[0021] Furthermore, the interlocking connection ensures a stable connection between the motor and the first connecting member. As a part of the motor, the shape and size of the convex plate match the fixing member, so that the two can be closely interlocked.

[0022] Furthermore, the connection plate is provided with a plurality of screw holes, and this design increases the reliability and stability of the connection. The plurality of screw holes are distributed at different positions, which can more evenly disperse the force between the connection plate and the volute, and reduce the risk of loose connection or damage caused by excessive local force.

[0023] Furthermore, the one-piece structure significantly improves the strength and stability of the connected components. Since there are no additional connectors or welding points, there are no potential weaknesses or risks of breakage between the parts of the one-piece molding, thus ensuring the solidity and durability of the entire assembly.

[0024] Furthermore, by providing a plurality of fixing holes on the fixing member and the convex plate and fixing with screws through these holes, the connection between the motor and the first connecting member can be ensured to be more firm and stable. This fixing method can not only withstand the vibration and impact force generated by the water heater during operation, but also effectively prevent performance degradation or safety hazards caused by loose connection.

[0025] Furthermore, the connection between the mounting plate and the smoke hood can be flexibly adjusted by means of screw assembly. During installation, the position of the mounting plate can be appropriately adjusted according to actual needs to achieve the best connection effect.

[0026] Other features and advantages of the present invention will be disclosed in detail in the following specific implementations and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0035] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the referred device or element must have a specific direction, be constructed and operated in a specific direction. Therefore, it should not be understood as a limitation on the present invention.

[0036] like Figures 1 to 4 As shown, a connection assembly for a gas water heater fan includes a first connection member 1 and a second connection member 2. The first connection member 1 is assembled between the motor 3 and the volute 4; the second connection member 2 is assembled between the first connection member 1 and the smoke hood 5; the stability and sealing of the entire fan system are ensured. The first connection member 1 includes a fixing member 1-1, a support plate 1-2 and a connecting plate 1-3; the fixing member 1-1 and the connecting plate 1-3 are vertically assembled at both ends of the support plate 1-2, and the first connection member 1 is a C-shaped structure, which can effectively withstand and disperse the vibration and stress from the fan, thereby improving the stability of the entire device; the second connection member 2 is vertically connected by the mounting plate 2-1 and the buckle plate 2-2, thereby achieving a close fit with the first connection member 1 and the smoke hood 5. Such a design not only ensures the firmness of the connection, but also facilitates installation and disassembly, and improves the convenience of repairing and replacing parts.

[0037] During installation, first assemble the first connecting member 1 on the motor 3. The fixing member 1-1 is in the shape of a groove, which is engaged with the convex plate 3-1 provided on the motor 3. The fixing member 1-1 and the convex plate 3-1 are both provided with a plurality of fixing holes 1-1-1. Screws pass through the fixing holes 1-1-1 to fix the fixing member 1-1 and the convex plate 3-1. Among them, the size of the convex plate 3-1 matches the groove depth of the fixing member 1-1, so that the connection is more stable. It is fixed by screws, which is easy to disassemble and install, and provides convenience for subsequent maintenance and replacement of parts.

[0038] Furthermore, a plurality of screw holes 1-3-1 are provided on the connecting plate 1-3 at the other end of the first connecting member 1, and the connecting plate 1-3 and the volute 4 are connected through the plurality of screw holes 1-3-1 and screws; thus, the connection between the first connecting member 1 and the volute 4 is more firm and stable. By providing a plurality of screw holes 1-3-1 on the connecting plate 1-3 and connecting it with the volute 4 through screws, multi-point fixation is achieved, thereby dispersing the force at the connection and enhancing the stability of the connection; the design of the plurality of screw holes 1-3-1 also provides greater flexibility, and an appropriate number of screws can be selected for fixing according to actual needs to adapt to different installation environments and requirements. At the same time, the connection method of the screw holes and screws is simple and reliable, and is easy to install and disassemble, which is conducive to subsequent maintenance and replacement of parts.

[0039] After assembling the first connector 1, assemble the second connector 2 between the first connector 1 and the smoke hood 5. The buckle plate 2-2 is equipped with a positioning column 2-2-2. The support plate 1-2 is provided with a positioning hole 1-2-1 through which the positioning column 2-2-2 passes. The cooperation between the positioning column 2-2-2 and the positioning hole 1-2-1 realizes the precise positioning between the first connector 1 and the second connector 2, thereby avoiding performance problems caused by installation deviation and increasing the stability of the connection. The positioning column 2-2-2 not only plays a positioning role, but also provides a certain supporting force after passing through the positioning hole 1-2-1 to prevent relative movement or loosening between the first connector and the second connector.

[0040] The lower surface of the support plate 1-2 is fitted with the upper surface of the buckle plate 2-2, and baffles 2-2-1 are provided on both sides of the buckle plate 2-2. The baffles 2-2-1 provided on both sides of the buckle plate 2-2 further enhance the stability and safety of the connection. The baffles 2-2-1 can effectively prevent the buckle plate 2-2 from being displaced or deformed when subjected to external forces, thereby ensuring the stability and durability of the connection.

[0041] Among them, the height of the positioning column 2-2-2 is higher than the height of the baffle 2-2-1, ensuring that the positioning column 2-2-2 can pass through the positioning hole 1-2-1 of the support plate 1-2 and form an effective support with the lower surface of the support plate 1-2. This support effect not only enhances the stability of the connection, but also effectively prevents the connection parts from relative movement or dislocation when subjected to external forces. The length of the support plate 1-2 is equal to the length of the buckle plate 2-2, so that the support plate 1-2 and the buckle plate 2-2 can be completely fitted when connected to form a tight connection surface, making the first connection part 1 and the second connection part 2 more stable, while making the connection assembly more beautiful and coordinated in appearance.

[0042] Furthermore, the positioning column 2-2-2, the mounting plate 2-1 and the buckle plate 2-2 are an integrally formed structure, and the fixing member 1-1, the support plate 1-2 and the connecting plate 1-3 are an integrally formed structure, which means that these components are formed as a whole during the manufacturing process without additional connection or assembly steps. This design reduces the seams and potential weaknesses between the components, thereby improving the strength and durability of the entire connection assembly.

[0043] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
