Technical Field
[0001] This utility model belongs to the technical field of blowers, specifically a blower motor assembly mounting structure, which enables the motor assembly to be quickly installed into the housing through a simple structure. Background Technology
[0002] Blowers are widely used in various places that require air exchange or exhaust gas, such as kitchens or above cooking stoves, to quickly remove exhaust gas. The existing blower includes an outer casing and a fan assembly. The fan assembly can be a single-axis fan assembly located on one side wall of the outer casing or a dual-axis fan assembly located inside the outer casing. Taking a blower with a dual-axis fan assembly as an example, its outer casing is usually composed of two semi-circular shells that can be combined with each other. The inner part of the outer casing has two roughly parallel and symmetrical vortex channels. Each vortex channel has an air inlet on one side wall of the outer casing and an air outlet for connecting a duct is formed on one side periphery of the outer casing. The dual-axis fan assembly has a motor assembly that can be installed in the center of the inner part of the outer casing. At both ends of the output shaft of the motor assembly, there are blade assemblies corresponding to the two vortex channels. This allows the dual-axis fan assembly to drive the blade assemblies on both sides to rotate at high speed in the vortex channels of the outer casing through the motor assembly. The air is introduced through the air inlet of the outer casing and discharged through the air outlet after being squeezed by the blade assembly and the vortex channel. Furthermore, the mounting design of the dual-axis fan assembly within the housing mainly involves a support ring rib formed at the center of the housing's perimeter, with several locking parts on this rib. Meanwhile, several opposing locking plates are formed at the center of the outer perimeter of the dual-axis fan assembly, allowing for the connection of the fan assembly to the locking parts of the support ring rib and the locking plates using screws or rivets. This approach not only requires more components, but the use of multiple locking devices also makes it easy for vibrations from the motor assembly to be transmitted to the housing, severely affecting the overall structural strength. It also makes the blower motor assembly prone to loosening or damage due to vibration, and may even generate resonance noise during operation.
[0003] In other words, the existing blower motor assembly installation design is not perfect, and there is a common problem that it cannot be installed quickly. It is also easy to loosen or be damaged due to vibration, and may even generate noise due to vibration. How to solve the aforementioned problems is something that the industry and users are eager to explore, and it is also the topic that this utility model aims to explore and solve.
[0004] Due to the aforementioned shortcomings and needs, the inventor of this utility model, drawing on years of experience in related technologies and product design and manufacturing, researched and created solutions to address these deficiencies and needs. Through continuous research and experimentation, a blower motor assembly installation structure was successfully developed to overcome the difficulties and inconveniences encountered during the installation of existing blower motor assemblies. Utility Model Content
[0005] Therefore, the main objective of this utility model is to provide a blower motor assembly installation structure that can effectively simplify the installation components, making the motor assembly installation simple and time-saving, and greatly improving its practicality.
[0006] Furthermore, a secondary objective of this utility model is to provide a blower motor assembly mounting structure that allows the motor assembly to be securely mounted within the housing, thereby reducing noise and damage caused by vibration, and reducing vibration during blower operation.
[0007] Therefore, this utility model mainly achieves the above-mentioned objectives and effects through the following technical means, including: An outer shell cover is composed of two opposing semi-circular shell covers. Each semi-circular shell cover has a semi-circular support portion in the middle of its inner edge. When closed, they together form a support ring rib. A vortex channel is formed on both sides of the support ring rib. An air inlet is provided at the outer end of each vortex channel. An upward-opening exhaust port is provided on the top of the outer shell cover. The exhaust port is connected to each vortex channel. The support ring rib is provided with at least three first mounting portions. Each first mounting portion has a tongue slot. A dual-axis motor assembly is disposed inside the housing cover, the dual-axis motor assembly comprising: A motor with a dual-head output shaft; Two housings are used to cover the motor and support the dual-head output shaft. Each housing has a second mounting part on its exterior that corresponds to each of the first mounting parts of the support ring rib. Each of the second mounting parts is provided with an inserting tongue for inserting into the tongue slots of each of the first mounting parts opposite to the support ring rib. The first mounting part is provided with a limiting flange and an elastic pad disposed thereon. The support part of the second mounting part can press against the elastic pad, thereby producing an elastic buffer clamping installation effect.
[0008] Through the specific implementation of the aforementioned technical means, the installation structure of the blower motor assembly of this utility model utilizes the fact that the outer casing is formed by two semi-circular shell covers being locked together, and that the supporting ring ribs of the outer casing have several first mounting parts and second mounting parts opposite to the dual-shaft motor assembly, so that it can be fixed in an interlocking manner. This not only simplifies the structure, but also facilitates quick installation and improves the stability of the connection, thereby effectively extending its service life, preventing damage due to vibration, reducing noise during operation, greatly improving its practicality, and further enhancing its added value and economic benefits.
[0009] Furthermore, this utility model utilizes the following technical means to further achieve the aforementioned objectives and effects; such as: The first mounting portions of each of the supporting ring ribs are arranged at equal angles, and the second mounting portions on the outside of each of the housings relative to the first mounting portions are arranged at equal angles accordingly. The dual-head output shaft has a circular fan blade at each end to generate airflow to draw in air through the air inlet and guide it to the air outlet through the vortex channel.
[0010] The elastic pad is made of rubber ring, foam pad or silicone material.
[0011] Each of the semi-circular shell covers is a one-piece molded structure made of plastic injection molding or metal molding.
[0012] Each housing has a bearing at its axis to support the dual-head output shaft, and each housing has a mating piece at its end edge that can fit together. Each mating piece has several locking parts so that a fastener can fix the motor inside the housing.
[0013] The exhaust vent is designed as an upward-facing ventilation hole and can be connected to a duct to guide the airflow outward.
[0014] Each of the housings has several ventilation holes formed on the wall surface adjacent to the circular fan blades to provide heat dissipation.
[0015] The beneficial effects of this utility model are: it effectively simplifies the installation components, making the motor assembly installation simple and time-saving, and greatly improving its practicality. It allows the motor assembly to be securely installed inside the housing, reducing noise and damage caused by vibration, and also reducing vibration when the blower is running.

All references to front and back, left and right, top and bottom, upper and lower, and horizontal and vertical are for ease of description only and are not intended to limit the present invention or restrict its components to any position or spatial orientation. The dimensions specified in the drawings and specification may be varied according to the design and requirements of specific embodiments of the present invention without departing from the scope of the patent application, and are therefore not limited to this structure in the patent application.
[0025] Regarding the composition of the blower motor assembly mounting structure of this utility model, it is as follows: Figure 1 , Figure 2 As shown, the blower includes at least a housing (100) and a dual-shaft motor assembly (500), wherein the dual-shaft motor assembly (500) is installed inside the housing (100), and a fan wheel (not shown) can be respectively installed on each shaft; The inner circumferential surface of the outer casing (100) has a ring-shaped support ring rib (105) that protrudes towards the axis, which is used to fix the dual-shaft motor assembly (500) inside the outer casing (100). The outer casing (100) has two vortex channels (101) that are roughly parallel and coaxially symmetrical on both sides of the support ring rib (105). Each vortex channel (101) has an air inlet (102) on each side wall of the outer casing (100), and an upward-opening exhaust port (103) is formed on the outer periphery of the outer contour of the outer casing (100). The exhaust port (103) connects to the two vortex channels (101) and is connected to a duct (not shown in the figure) so that gas is drawn in from the two air inlets (102) and discharged outward from the exhaust port (103) after passing through the two vortex channels (101). Furthermore, the outer casing (100) is composed of two semi-circular shell covers (10) that can be closed relative to each other. Each semi-circular shell cover (10) is an integral structure made of plastic material by injection molding or metal molding. Each semi-circular shell cover (10) has a corresponding semi-circular support portion (11) formed in the middle of its inner edge, which forms the support ring rib (105) when the semi-circular shell covers (10) are closed relative to each other. In addition, each semi-circular shell cover (10) has a corresponding support ring rib formed on both sides of the semi-circular support portion (11). The semi-circular air duct (12) is used to form the vortex channel (101) when the semi-circular shell cover (10) is closed, and the two side walls of the semi-circular shell cover (10) are respectively formed with a semi-circular notch (13) connecting the semi-circular air duct (12) to form the air inlet (102) when the semi-circular shell cover (10) is closed. Furthermore, the semi-circular support (11) has at least three first mounting parts (16) arranged at equal angles for locking the dual-shaft motor assembly (500). like Figure 2 , Figure 3As shown, the dual-axis motor assembly (500) has a motor (50), and the motor (50) has a dual-head output shaft (51) at its shaft. The motor (50) also has two housings (53) that can be closed relative to each other. The housings (53) have a bearing (54) at their shafts to support the dual-head output shaft (51) of the motor (50). The end edges of the housings (53) are respectively formed with a mating piece (55) that can be fitted relative to each other. The housings (53) have a number of locking parts (5) arranged at equal angles on the mating pieces (55). 51) For example, screw holes or through holes, for use with a number of fasteners (552) such as screws or rivets, so that the motor (50) can be fixed inside the housings (53), and the two ends of the dual-head output shaft (51) of the motor (50) can be pivoted through the housings (53) on both sides respectively, and the two ends of the dual-head output shaft (51) can be respectively equipped with a circular fan blade disk (not shown in the figure), and the housings (53) have a second mounting part (56) relative to each of the first mounting parts (16), so that the dual-shaft motor assembly (500) can be installed inside the outer housing (100); The feature of this utility model is as follows: Figures 2 to 6 As shown, the first mounting portion (16) on the support ring rib (105) of the outer casing (100) may include tongue slots (161) on both sides, and the first mounting portion (16) has a limiting flange (162) for fitting an elastic pad (163). The elastic pad (163) is made of rubber ring, foam pad or silicone material, and the second mounting portions (56) opposite to the first mounting portions (16) each have an inserting tongue (561), so that the casing (53) can utilize the second mounting portions (561) 6) The insert tongue (561) is engaged in the opposite tongue groove (161) of the first mounting part (16) of the support ring rib (105) to generate a clamping effect, and there is a support part (562) between the insert tongues (561) on both sides of the second mounting part (56) that can press against the elastic pad (163), so that when the dual-shaft motor assembly (500) is fixed to the first mounting part (16) of the support ring rib (105) of the outer casing (100) by the second mounting part (56), an elastic buffering effect can be generated; This allows for the creation of a blower motor assembly structure with fewer components, a simplified structure, and reduced noise.
[0026] However, there is another preferred embodiment of this utility model, which is as follows: Figure 7 As shown, each of the housings (53) of the dual-shaft motor assembly (500) has a number of ventilation holes (530) formed on the wall surface adjacent to the circular fan blades, for the gas flow of the motor (50) inside the housings (53), so that the motor (50) of the dual-shaft motor assembly (500) has a heat dissipation function.
[0027] As can be seen from the aforementioned structural design and operation description, the blower motor assembly mounting structure of this utility model utilizes the outer shell cover (100) which is formed by the relative locking of the semi-circular shell cover (10). Furthermore, the outer shell cover (100) has a plurality of first mounting parts (16) and second mounting parts (56) opposite to the dual-shaft motor assembly (500) through the support ring rib (105), which allows it to be fixed by an insert method without the need to use additional fasteners such as bolts as in the present invention. This not only simplifies the structure but also facilitates quick installation and improves the stability of the connection, thereby effectively extending its service life. It also prevents damage due to vibration and reduces noise during operation, greatly enhancing its practicality.
[0028] In conclusion, it can be understood that this utility model is a highly inventive utility model. In addition to effectively solving the problems faced by the inventors, it greatly improves the efficiency. Moreover, no identical or similar products have been created or publicly used in the same technical field. Since it also improves the efficiency, this utility model meets the requirements of "novelty" and "inventiveness" for utility model patents, and therefore a utility model patent application is filed in accordance with the law.
